Abstract
The invention concerns a one-piece dispensing device which can be used for the contamination-free administration of medicaments (cytostatica) and is particularly suitable for use in ambulant treatment. The aim of the invention is to design a connector for connecting medicament (cytostatica) containers to the instruments by which the medicaments are administered, the connector being designed to prevent, without a complex apparatus, contamination of the medicament container surroundings during connection of the container and until its disposal. This is achieved according to the invention by the provision of at least one coupling member (1) to create a non-releasable connection with a medicament container, said coupling member (1) having an insertion pin (2) and barbed surfaces (10) to accommodate the medicament container. The coupling member (1) is non-releasably connected via a hose (3, 31) to a flexible container (4; 41) which can be filled exclusively with gas until the device is first used. The container (4; 41) is non-releasably connected to a further tubular outlet (6) and a mechanically actuated stop valve (5, 7) is incorporated in each of the connecting ducts (3, 31, 6).
Description
ONE-PIECE DISPENSING DEVICE FOR THE
CONTAMINATION-FREE ADMINISTRATION QF
MEDl~AME~TS ~ OSTATICA) 5 BACKGROUND OF T~E INVENTION
The invention relates to a one-piece dispensillg device for co~ tion-free ~-lmini~ tion of me~ir~rnents ~cytostatica), pa~ticularly for use in ambulant tre~tm~nt For mixin~ and transferring ph~ ceutical solutions from one 10 container to at least another one it is requ~ed to embody the connection in such a manner that an escape of ph~rm~ceutic agents and, thus, a coll~ ;on of the colltailler s~face and of the health care workers is elimin~te~l ~n par~cula~ w~ respect to the mi~m~
and ~(iminictration of highly toxic cyto~tatic solutions which can 15 cause diseases when escaping uncontrolled a col-t~ tion-free transfer and mixin-~ is required.
According to the state of art the ir~sion solution and the dry or liquid form drugs are ~timixed by a syringe and by the removal from and the addition to, respec~vely, di~ l cc)nt~inerS~ before the the 20 ixed infusion solution is ready for infi~ion. Coll~lnin~tions cannot be elim;n~te~l due to the pressu~e possibly occ~ng in the diE~lelll containers and to the free h~n~llin~ of the syringe. Such a practice requires working ullder respective suction apparatus which is considerably disturbing in medical work. F~ llelmore, particularly embodied injection ports on in~usion containers have been proposed, which improve the mixin~ of the agents mentioned but do not elimiTt~te the problem of c~ t;l~;on. A fu~er improvement of the same object is kllo~ from tlle EP 0 363 770 A1 whi~ discloses s a co.nnector for ph~ ceutic sol~;on~, and from EP0330130 a container for infilsion solutions. The co~ector described in the EP 0 363 770 subst~nti~lly cQnsists in a tubu~ar coupli~g portion and a shuto-ff device for closing the fo~ r. With said solution the coupling portion is constituted of a ~llow insertion pin a~d a hollow o portion attached thereto which pe~ s insertion into a hose-like connectQr of a cont~in~r. The hQl;low part~on is closed by a stop-cock detachable from out~ide. It tumed Ollt when operating said solution that even when employ~g connected cont~iners having a ~bber stopper seal an em~ssion ~aerosols cam~t be elim;n~te~ for sure.
Furthermore, connectors are known from the US Patent Specification 4,675,020 and ~om the EP 0 028 198 which do not solve the problem of co"~ tiQn as desired a~ ~X;onally~ ~ust as the other ill~e~tional solutiQns do, only permit the con~ection of two cont~iners filled with ph~rrn~ceutic solutions. This involves that such solutions are not or on~y cor~itionally applicable when, for example, the dissolving of an agent req~res two solvents.
SU~MARY OF TEll~ IN~NTION
It is an object of the invention to provide a connector for joining drug ` 218895~
(cytostatica) cont~iners to an ~(lmini~tration system which elimin~tes any co~ t;on of the drug container ambience from the connecting state u~ to the removal of residuals and which does without consideldble e~elldiL~es in al~pa~ s.
BRIEF DE:SCRIPTIONS OF TEE~ INVENTION
The object of the invention is re~ e~ by the features of the claims.
The invention provides a con~ector which is particularly ap~cable in ambulant tre~t~ent and which, when used, does not put high le4uL~ entC to the medical care wo~cers and releases the latter from any co~ on problems.
D~T~ 1) DES~RIPTION OF TIIE INV~NTION
The invention will be e~lained in more detail by the following embo~liment~
There is shown in Fig. 1 an embo~lim~nt of the inventiQn for ~imini~tering drugs ~cytostatica) in liquid form, Fig. 2 an embo~1iment for dissolving drugs sold in s~}id form (cytostatica) and for mixin~ two ~quid ~ugs, respectively, Fig. 3 an embodiment particularly for dissolving drugs sold in solid form, in whi-ch a supply mealls for variable amo~ts of solvents is provided, and Fig. 4 a detailed representation of a one piececoupling according to the invention.
~n Fig. 1 a connector is shown COll~liSil~g a coupling nlel~
s which L~cludes an in~rtion pin 2. Said coupling member~ ~ia a hose connection 3, 31, is non-detachably coPnected by adhesives or by welding to a flexible cont~ r 4 which permits filling wit-h a gas. A
mecha~cally operable stop valve 5 is provided in said hose connection. Furthermore, the flexible cont~incr 4 also i~ erably o non-det~çh~bly provided with a hose-~ke outlet 6. A further mech~nir~l stop valve 7 is int~ ng~l in the outlet 6. The outlet 6 permits appen ling of not shown hose connection to p~ti~nt~, such as conventional catheters. Said coupling member 1 consists of a cup-shaped inelasti~ hoElow body l l wE~ch has an interior reception profile 12. The hollow body 11 is prc~lably and additionally coated with not shown e~astic seali,lg mearls. Said reception profile 12 tapers towards int~rior an~ carrLes barbed areas 13. ~n order to ~ nini~ter a drug (cytostatica) a~7ailable in cont~iners~ the neck of which permits insertion iato the c~upling member 1, the drug 20 container 100, schematically indicated in ~g. 3, is inserted into the coupling member 1 and ~}resscd on the latter. Typically the height of the pe~ lion depth ofthe illsellioll pm 2 l~lali~e to the b~l,ed area 13 is so defined that~ wh~ the insertion pin 2 has pierced the insertion base of the drug container 1~0, the barbed areas 13 ca~ch corresponding counter areas of the neck of the drug container 100 and thus non-detachably connect the latter to the coupling member 1.
Thus it is e~ured that d~ing connection and infi~sion subsequently callied out neiLL~r the hea~ care workers nor the e.,vilollll.cl~t is 5 cc,~ te~l by aerosoLs or t~e like P~ tecl from the drug contzliner.
Subsequent to the established connection of the drug Cont~iner 100 a path is opened via a mechanica~y operable stop valve S to a sterile flexible receptacle 4 which is, for example, f~led wit~ air. It is feasible to press the air into the dr~g container 100 and subsequently 10 the rc.lu~ed de~leable dosage of the liquid d~ug is wilhd~w~ from and released into, respectively, the receptacle 4. Only then the path for the drug to the patient is opened via the hose-like outlet 6 which can be turned On by a stop valve 7. Conduction means attached to the outlet 6 and conventionally connected to an adapter ph~g no~zle 15 61 of the outlet 6 are not represented in more detail.
In Fig 2 a further inventio~l so~tion is sho~ ~1ilT~,;"g from the solution of Fig. 1 by a di~er~l~ embo~ P.nt above the hose-connection 31 along a line X-X. Typically, two hose connections 32 20 branch off from the hose co~nection 31, no~detachably connected to the latter, each of which includes a meehanica~y operable stop valve S and 51, respectively. In a ~refe.~dble embodilllent both hose-connections 32 are each provided with a coupling member 1 in analogy to Fig. 1. Said embodiment particularly is sl~itable for ` 2188953 ~lmini~tering drugs (cytostatica) on sale in dry form, such as powder. The procedure is as follows: at f~st the first coupling member 1 is connected to a cont~;ner with an a~propl;ate solvent inside and, subsequently, the second co~li~ ber 1 is co~ ected 5 with a cont~iner cort~inin~ the drug to be p~se~l into solution. After opening the stop valve 51 an ay~ro~liate volume of the solvent passes into the flexible receptacle 4, the stop valves 7 and 5 being in the OFF-state. Then the stop valve 51 is closed and the stop valve 5 opened to release the path to the container wit~ the drug (cytostatica) 10 to be passed into solution, the flexible receptacle 4 being kept under pressure. Subsequent to the solution process the dissolved drug is p~ illed to return to the receptacle 4. The valves S and 51 are set to the OFF-state and the dissolved drug can be ~(lmini~tered as described in analogy to Fig. 1. It is obvious also to emp-loy the S embodiment according to Fig. 2 for dosed mi~in~ of two liquid drugs the cont~iners of which are connectable to said first and said second coupling member 1.
Fig. 3 shows a particula~ly advantageou~ inventional ~imini.~tering 20 device, comprising acoupl~ngmember 1 also including an insertion y~in 2. Said couplir~g member 1 is non-detachably connected by adhesives or welding to a flexible gas-filled self-~uyyollmg receptacle 41 via a hose-comlection 31. A m~ch~nically operable stop valve S is provided within the hose-connection. Furthe~ore, in 218895~
analogy to Fig. 1, said receptacle 41 is, preferably non-detachably, provided with a hose-lil~e outlet 6, integrated i-nto which is a further mechanical stop valve 7.
In a further p~i~;ul~l~ adv~eous elllbo-l"~ "t of the pre~ent s invention, a secon~ hase-connectiQn 32 br~nrh~s off the hose-connection 31, also non-detachably comlectec~ with one another. A
no~Llulll valve 52 is ~ovided in said second hose-connection 32 operating as a mechanical stop valve with the locking ef~ect in opposite direction to the flexible lece~tacle 41. The nollre~ l valve o 52 is provided with a socket 521 adal~ted for receivillg a cone-shaped connection piece 9. Said socket 521 prefer~kly is embodied as a Luer-lock joint which in particular is æd~pte~ for receiving the tapering end portions of a conventi~n~l syringe. Furthermore, it is feasible to insert an ana-logous stop valYe S between the nonreturn 15 valve and the hose co~ection 3.
According to the invention, the Luer-lock Joint is ~l~fel~bly embodied in such a m~nner that the same when inserted into the non~ valve opens the latter via the nozzle end-portion 9 of the syrirlge when the comlection is effected. The proposed solution is 20 particularly suited for ~mini~tration of drt~gs ~cytostatica) which are at one`s disposal in dry form, such as powder. ~he proceeding is as follows: at f~rst the contailler 100 which colllaills the dr~g to be dissolved is connected by exer~g pressure in a direction indicated by the ar~ow; the path to the hose GQMle~ion 31 beiIlg sti~l closed by -the stop valve 5. T~en a syringe which is conventionally and variably filled with a sodium chloride solution, depe~ing on the dosage of the dry form drug to be dissolved, is inserted via its nozzle end portion 9 into the Luer-lock jomt 521 to effect colllact with the same and to 5 open the nol~e~ , valve 52. The solvent is now pe~ d to enter the flexible and self-supporting gas-, preferably, air-filled receptacle 41. Subsequently, the synnge is removed a-nd the nol~el~ valve 52 ensures a col.l1...;ll~t;or~free seal towa-rds ambience. When it is required that the syringe or any other replacement cont~iner for the l0 solvenl remain in the colll~ected state a further stop valve 5 has to be provided between the no~ valve 52 and the hose comlectiQn 31.
Said stop valve 5 has to be closed after the solvent has been filled in the receptacle 41. Only then the first stop valve 5 to the coupling member 1 is opened, an a~ r~pliate dosage ~f the solvent is pressed 15 into the container with the drug to be dissolved and, after dissolution, the solution is ~ s~lled into the receptacle 41. The dlug container 100 rem~in~ in an ~irt;ght an~ non-det~ch~Je con~ectiQn wi:th the member 1 and the fi~st stop valve 5 is closed. It lies within the scope of the invention to embody the st~ valve 5 as a three-way valve 20 installed adjacent the receptacEe 41 in the h~}se connection 31.
The release of the dissolved dr~g to the patient is obtained by o~ening the stop valve 7.
In contrast to the embot1imPnt accor~g to Fig. 2 where the so~ent for m;~ing solutions have to be at one`s disposal in doses as on sale 21889~3 -and in prepared cont~iners, what might, in particular, involve difficulties in small medical practices due to the fact that, for example, sodium chloride solutions as rule are only available in large fillin~, in contrast ~ elo the e~bo-l;"~e.ll accor~i~g to Fig 3 has s the advantage that, due to the illvel~ional embollim~nt of a second connection port, a co.~l~,,,it~t;on-fFee coupling of a conventional syringe with variable dosage is feasible. Furt~e-more, the range of d-rug doses to be dissol~ed is e~ten~1e~ at will.
o Fina-lly, Fig. 4 le~r~se.ll~ a partiaLly se-;liollall~ view of a coupling member 1 in more detaiL. ALl elem~nt~ ~lesipn~te~l nameLy~ insertion pin 1, hollow body 1.1, reception profile 12, and a connection piece 8, which ~refelably are made of plastics, according to the invention are embodied as one piece, that is, also the insertion pin 2 is integral 15 part of the coupling member 1. Preferably, it is feasible to ".~.".r~clule the entire coup~g ~mber 1 as a one-piece injection-moulded member. The notches 21 shown which also are generated with the plastics inJection moulding of t~e cou~ling member 1 are a~apted to receive corres~nding co~lel~aFts on the drug container.
The illv~lllional subject matter is not restricted to the number of colmeclions disclosed. It, however, is esse~ial that a flexible receptacle 4, 41 pe...~ ;..E gas filling is employed which is provided wi~ at least two connection lines which permit a selective opening ` 2188953 -and closing to a definitely embodied coupling means and in direction of the dlug delivery, respectively. TypicalIy, the entire ~flmini~tration system including the already gas-filled (~lef~.dbly air) receptacle can be made available in sterile folm or it is feasible to fill the r~ceptacle 5 with a gas only prior to appL;cation.
The entire fe~ es disclosed in the specification, in the attached claims and represented in the dr~gs can be essential for the i,~ve~tion individualIy an~l in any combination.

A fu~er improvement of the same object is kllo~ from tlle EP 0 363 770 A1 whi~ discloses s a co.nnector for ph~ ceutic sol~;on~, and from EP0330130 a container for infilsion solutions. The co~ector described in the EP 0 363 770 subst~nti~lly cQnsists in a tubu~ar coupli~g portion and a shuto-ff device for closing the fo~ r. With said solution the coupling portion is constituted of a ~llow insertion pin a~d a hollow o portion attached thereto which pe~ s insertion into a hose-like connectQr of a cont~in~r. The hQl;low part~on is closed by a stop-cock detachable from out~ide. It tumed Ollt when operating said solution that even when employ~g connected cont~iners having a ~bber stopper seal an em~ssion ~aerosols cam~t be elim;n~te~ for sure.
Furthermore, connectors are known from the US Patent Specification 4,675,020 and ~om the EP 0 028 198 which do not solve the problem of co"~ tiQn as desired a~ ~X;onally~ ~ust as the other ill~e~tional solutiQns do, only permit the con~ection of two cont~iners filled with ph~rrn~ceutic solutions. This involves that such solutions are not or on~y cor~itionally applicable when, for example, the dissolving of an agent req~res two solvents.
SU~MARY OF TEll~ IN~NTION
It is an object of the invention to provide a connector for joining drug ` 218895~
(cytostatica) cont~iners to an ~(lmini~tration system which elimin~tes any co~ t;on of the drug container ambience from the connecting state u~ to the removal of residuals and which does without consideldble e~elldiL~es in al~pa~ s.
BRIEF DE:SCRIPTIONS OF TEE~ INVENTION
The object of the invention is re~ e~ by the features of the claims.
The invention provides a con~ector which is particularly ap~cable in ambulant tre~t~ent and which, when used, does not put high le4uL~ entC to the medical care wo~cers and releases the latter from any co~ on problems.
D~T~ 1) DES~RIPTION OF TIIE INV~NTION
The invention will be e~lained in more detail by the following embo~liment~
There is shown in Fig. 1 an embo~lim~nt of the inventiQn for ~imini~tering drugs ~cytostatica) in liquid form, Fig. 2 an embo~1iment for dissolving drugs sold in s~}id form (cytostatica) and for mixin~ two ~quid ~ugs, respectively, Fig. 3 an embodiment particularly for dissolving drugs sold in solid form, in whi-ch a supply mealls for variable amo~ts of solvents is provided, and Fig. 4 a detailed representation of a one piececoupling according to the invention.
~n Fig. 1 a connector is shown COll~liSil~g a coupling nlel~
s which L~cludes an in~rtion pin 2. Said coupling member~ ~ia a hose connection 3, 31, is non-detachably coPnected by adhesives or by welding to a flexible cont~ r 4 which permits filling wit-h a gas. A
mecha~cally operable stop valve 5 is provided in said hose connection. Furthermore, the flexible cont~incr 4 also i~ erably o non-det~çh~bly provided with a hose-~ke outlet 6. A further mech~nir~l stop valve 7 is int~ ng~l in the outlet 6. The outlet 6 permits appen ling of not shown hose connection to p~ti~nt~, such as conventional catheters. Said coupling member 1 consists of a cup-shaped inelasti~ hoElow body l l wE~ch has an interior reception profile 12. The hollow body 11 is prc~lably and additionally coated with not shown e~astic seali,lg mearls. Said reception profile 12 tapers towards int~rior an~ carrLes barbed areas 13. ~n order to ~ nini~ter a drug (cytostatica) a~7ailable in cont~iners~ the neck of which permits insertion iato the c~upling member 1, the drug 20 container 100, schematically indicated in ~g. 3, is inserted into the coupling member 1 and ~}resscd on the latter. Typically the height of the pe~ lion depth ofthe illsellioll pm 2 l~lali~e to the b~l,ed area 13 is so defined that~ wh~ the insertion pin 2 has pierced the insertion base of the drug container 1~0, the barbed areas 13 ca~ch corresponding counter areas of the neck of the drug container 100 and thus non-detachably connect the latter to the coupling member 1.
Thus it is e~ured that d~ing connection and infi~sion subsequently callied out neiLL~r the hea~ care workers nor the e.,vilollll.cl~t is 5 cc,~ te~l by aerosoLs or t~e like P~ tecl from the drug contzliner.
Subsequent to the established connection of the drug Cont~iner 100 a path is opened via a mechanica~y operable stop valve S to a sterile flexible receptacle 4 which is, for example, f~led wit~ air. It is feasible to press the air into the dr~g container 100 and subsequently 10 the rc.lu~ed de~leable dosage of the liquid d~ug is wilhd~w~ from and released into, respectively, the receptacle 4. Only then the path for the drug to the patient is opened via the hose-like outlet 6 which can be turned On by a stop valve 7. Conduction means attached to the outlet 6 and conventionally connected to an adapter ph~g no~zle 15 61 of the outlet 6 are not represented in more detail.
In Fig 2 a further inventio~l so~tion is sho~ ~1ilT~,;"g from the solution of Fig. 1 by a di~er~l~ embo~ P.nt above the hose-connection 31 along a line X-X. Typically, two hose connections 32 20 branch off from the hose co~nection 31, no~detachably connected to the latter, each of which includes a meehanica~y operable stop valve S and 51, respectively. In a ~refe.~dble embodilllent both hose-connections 32 are each provided with a coupling member 1 in analogy to Fig. 1. Said embodiment particularly is sl~itable for ` 2188953 ~lmini~tering drugs (cytostatica) on sale in dry form, such as powder. The procedure is as follows: at f~st the first coupling member 1 is connected to a cont~;ner with an a~propl;ate solvent inside and, subsequently, the second co~li~ ber 1 is co~ ected 5 with a cont~iner cort~inin~ the drug to be p~se~l into solution. After opening the stop valve 51 an ay~ro~liate volume of the solvent passes into the flexible receptacle 4, the stop valves 7 and 5 being in the OFF-state. Then the stop valve 51 is closed and the stop valve 5 opened to release the path to the container wit~ the drug (cytostatica) 10 to be passed into solution, the flexible receptacle 4 being kept under pressure. Subsequent to the solution process the dissolved drug is p~ illed to return to the receptacle 4. The valves S and 51 are set to the OFF-state and the dissolved drug can be ~(lmini~tered as described in analogy to Fig. 1. It is obvious also to emp-loy the S embodiment according to Fig. 2 for dosed mi~in~ of two liquid drugs the cont~iners of which are connectable to said first and said second coupling member 1.
Fig. 3 shows a particula~ly advantageou~ inventional ~imini.~tering 20 device, comprising acoupl~ngmember 1 also including an insertion y~in 2. Said couplir~g member 1 is non-detachably connected by adhesives or welding to a flexible gas-filled self-~uyyollmg receptacle 41 via a hose-comlection 31. A m~ch~nically operable stop valve S is provided within the hose-connection. Furthe~ore, in 218895~
analogy to Fig. 1, said receptacle 41 is, preferably non-detachably, provided with a hose-lil~e outlet 6, integrated i-nto which is a further mechanical stop valve 7.
In a further p~i~;ul~l~ adv~eous elllbo-l"~ "t of the pre~ent s invention, a secon~ hase-connectiQn 32 br~nrh~s off the hose-connection 31, also non-detachably comlectec~ with one another. A
no~Llulll valve 52 is ~ovided in said second hose-connection 32 operating as a mechanical stop valve with the locking ef~ect in opposite direction to the flexible lece~tacle 41. The nollre~ l valve o 52 is provided with a socket 521 adal~ted for receivillg a cone-shaped connection piece 9. Said socket 521 prefer~kly is embodied as a Luer-lock joint which in particular is æd~pte~ for receiving the tapering end portions of a conventi~n~l syringe. Furthermore, it is feasible to insert an ana-logous stop valYe S between the nonreturn 15 valve and the hose co~ection 3.
According to the invention, the Luer-lock Joint is ~l~fel~bly embodied in such a m~nner that the same when inserted into the non~ valve opens the latter via the nozzle end-portion 9 of the syrirlge when the comlection is effected. The proposed solution is 20 particularly suited for ~mini~tration of drt~gs ~cytostatica) which are at one`s disposal in dry form, such as powder. ~he proceeding is as follows: at f~rst the contailler 100 which colllaills the dr~g to be dissolved is connected by exer~g pressure in a direction indicated by the ar~ow; the path to the hose GQMle~ion 31 beiIlg sti~l closed by -the stop valve 5. T~en a syringe which is conventionally and variably filled with a sodium chloride solution, depe~ing on the dosage of the dry form drug to be dissolved, is inserted via its nozzle end portion 9 into the Luer-lock jomt 521 to effect colllact with the same and to 5 open the nol~e~ , valve 52. The solvent is now pe~ d to enter the flexible and self-supporting gas-, preferably, air-filled receptacle 41. Subsequently, the synnge is removed a-nd the nol~el~ valve 52 ensures a col.l1...;ll~t;or~free seal towa-rds ambience. When it is required that the syringe or any other replacement cont~iner for the l0 solvenl remain in the colll~ected state a further stop valve 5 has to be provided between the no~ valve 52 and the hose comlectiQn 31.
Said stop valve 5 has to be closed after the solvent has been filled in the receptacle 41. Only then the first stop valve 5 to the coupling member 1 is opened, an a~ r~pliate dosage ~f the solvent is pressed 15 into the container with the drug to be dissolved and, after dissolution, the solution is ~ s~lled into the receptacle 41. The dlug container 100 rem~in~ in an ~irt;ght an~ non-det~ch~Je con~ectiQn wi:th the member 1 and the fi~st stop valve 5 is closed. It lies within the scope of the invention to embody the st~ valve 5 as a three-way valve 20 installed adjacent the receptacEe 41 in the h~}se connection 31.
The release of the dissolved dr~g to the patient is obtained by o~ening the stop valve 7.
In contrast to the embot1imPnt accor~g to Fig. 2 where the so~ent for m;~ing solutions have to be at one`s disposal in doses as on sale 21889~3 -and in prepared cont~iners, what might, in particular, involve difficulties in small medical practices due to the fact that, for example, sodium chloride solutions as rule are only available in large fillin~, in contrast ~ elo the e~bo-l;"~e.ll accor~i~g to Fig 3 has s the advantage that, due to the illvel~ional embollim~nt of a second connection port, a co.~l~,,,it~t;on-fFee coupling of a conventional syringe with variable dosage is feasible. Furt~e-more, the range of d-rug doses to be dissol~ed is e~ten~1e~ at will.
o Fina-lly, Fig. 4 le~r~se.ll~ a partiaLly se-;liollall~ view of a coupling member 1 in more detaiL. ALl elem~nt~ ~lesipn~te~l nameLy~ insertion pin 1, hollow body 1.1, reception profile 12, and a connection piece 8, which ~refelably are made of plastics, according to the invention are embodied as one piece, that is, also the insertion pin 2 is integral 15 part of the coupling member 1. Preferably, it is feasible to ".~.".r~clule the entire coup~g ~mber 1 as a one-piece injection-moulded member. The notches 21 shown which also are generated with the plastics inJection moulding of t~e cou~ling member 1 are a~apted to receive corres~nding co~lel~aFts on the drug container.
The illv~lllional subject matter is not restricted to the number of colmeclions disclosed. It, however, is esse~ial that a flexible receptacle 4, 41 pe...~ ;..E gas filling is employed which is provided wi~ at least two connection lines which permit a selective opening ` 2188953 -and closing to a definitely embodied coupling means and in direction of the dlug delivery, respectively. TypicalIy, the entire ~flmini~tration system including the already gas-filled (~lef~.dbly air) receptacle can be made available in sterile folm or it is feasible to fill the r~ceptacle 5 with a gas only prior to appL;cation.
The entire fe~ es disclosed in the specification, in the attached claims and represented in the dr~gs can be essential for the i,~ve~tion individualIy an~l in any combination.
