TRANSFUSI ON DEVICE FOR BOTTLES CONTAI NI NG MEDICALLY
ACTIVE LIOUID
SPECI FI CATI ON
BACKGROUND OF ~HE INVENTION
The invention relates to a transfusion device for bottles filled with medieally aetive liguids whieh are dispensed in a steady flow of drip~ while the bottle is held inverted. The device eomprises a connector section adapted to the opening of the bottle, a tube attached to this connector ~-~
and used for delivering the liquid to patient, and also a closable air duet.
When in use for tube feeding of patients, the eonnectors of transfusion devices of the kind referred to here are forced onto the openings of, for example, crown cap bottles containing the nutrient liquid. When the eonnectors are forced onto the bottles, it often happens that liquid runs -into the air duet, even if the latter is fitted with a riser tube that extends deep into the bottle.
When this occurs it can prevent any further ventilation -~
from taking place and the flow of liquid ceases. In addition, the liquid - which may be sticky - very often escapes from ;~
the out~ide opening of the air duct. This makes it very ;
awkward and unhygienic to handle the bottles and the transfusion device. ;~
~ SUMMARY OF THE INVENTION
The of the invention is to improve the above-mentioned transfer deviee in such a manner that ventilation i6 maintained at all times and no liquid eseapes through the air duct.
This task is accomplished in the device according to the invention by using a hydrophobic filter to close off the opening of the air duct inside the bottle. In general terms, the invention provides a transfusion device for bottles filled with a medically active liquid or the like whioh is dispensed in a steady flow of drips while the bottles are held inverted, the device comprising, in combination~
(a) a connector section ineluding conneeting means for ~ ~-h ~ ) 5~ 7 )~
connecting the device to a respective bottle, said connector section further including with a tube for delivering the liquid from a reepective bottle to a patient;
(b~ an air duct including an exterior air inlet, closure means for selectively closing or opening said air inlet, and an air discharge end having an air discharge opening, said air duct being arranged such that the air discharge opening is disposed in the interior of a 10respective bottle when the device is installed; and (c) a hydrophylic filter covering said air discharge end.
Even when transfusion devices equipped with a hydrophobic filter in the manner according to the invention are removed several times and fitted on other bottles, it is no longer possible for liquid to enter into the air duct.
Ventilation is therefore guaranteed at all times and no liquid can escape into the environment.
Using hydrophobic filters to close off air ducts in ;~
liquid-filled bottles is, in principle, a known practice in the field of infusion technology. However, in this known aase, it is the other, namely the outer end of the air duct which i8 closed off with a filter in order to prevent foreign bodies from penetrating into the 6ystem from outside. In the known case, no thought is given to the need to prevent liquid from entering into the air duct from inside the bottle itself. The designers of such bottles went to great lengths to prevent the filter from becoming directly wetted by the liquid. Although in the devioe according to the invention the filter comes into direct contact with the liquid when the ~;
connector is fitted onto the bottle, tests have shown that the filter remains fully effective.
In accordance with a further refinement of the -~
invention, the air duct possesses inside the bottle a riser~;
tube whose free end is fitted with a hydrophobic filter. By arranging the hydrophobic filter so that it is "up" (when the 2 ~ r~ ~7 bottle is inverted for use), the necessary difference between the air inlet and the liquid outlet (this difference should be as large as possible) is obtained, thereby guaranteeing trouble-free functioning in all cases.
Further characteristic features and possible applications of the invention are apparent from the description of the embodiments depicted in the drawings. ; - -BRIEF DESCRIPTION OF THE DRAWIN~S

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Flgure 1 shows the es~ential parts of a transfusion device for a bottlé 1 filled with a mediaally active liquid ~
which is dispensed in a steady flow of drips, the bottle is --25 held in the inverted position. -The transfusion device is provided with a connector piece 3 adapted to fit the opening of the bottle, and having a flange section 4 engaging the edge of the bottle 2 and also provided with an opening 5 through which the liquid can pass.
The connector is integrally linked with a drip chamber 6 at the outlet l of which a tube 8 is attached for delivering the fluid to a patient. The further configuration of this delivery tube 8 is known and requires no further description here.
In order to ventilate the interior of the bottle when the liquid drains from it, the transfu~ion device is provided ;~
with an air duct 9 which opens into a short socket 10 in the flange section 4. A normally generally upright portion, in the embodiment shown, a ri~er tube 11, is fitted in this socket, and the upper end of the riser tube is closed by a hydrophobic filter 12. In the embodiment according to Fig. 1, ;`
the filter 12 is fitted over the riser tube 11. The filter 12 -consists of a filter housing with a filter element 1~, whose throughflow direction i6 coaxial with the axis of the rlser tube.
In an initial embodiment, the air duct 9 may advantageously be designed in such a way that it can be 20 closed on the air inlet side, e.g. by means of a pendant plug -~
14 bearing a pin 15 shaped to fit the air duct.
In a second embodiment, the air duct 9 is left pexmanently open because the plug 14 with the pin 15 are no longer provided. This latter configuration is preferred as far as manufacture by the injection moulding process is concerned.
According to a form of the invention as illustrated in Figure la, the filter element 13 may also be inserted ' .: ''; '~ ..'~'.
,''. '..: ~ ~, r~ 7 , , directly into the upper end of the riser tube 11, so that it is flush with the air discharge opening of the riser tube 11. ~ -As a result, there is no need for a filter housing.
In accordance with a further embodiment of the invention, as illustratad in Figure lb, the filter element 13 is fitted peripherally in the wall of a filter housing having the shape of an end cap, and the throughflow direction of the filter i8 perpendicular to the axis of the riser tube.
Thi~ latter configuration according to Figure lb permits unwanted liquid on the filter to drain off reliably after the riser tube has been immersed in the contents of the bottle.
Figure 2 depicts another possible configuration of a connector section of a transfusion device according to the invention. Parts which are identical with the embodiment lS illustrated in Figure 1 are identified by the same reference numbers.
In the configuration shown in Fig. 2, the hydrophobic filter 12 is fitted directly, i.e. without a riser tube, to the connector section 3. In principle, this could be done by ~-~
20 attaching the filter 12 directly to the normally generally -upright socket 10. However, it is more favourable to extend the air duct 9 by means of another type of a normally generally upright portion, in thi~ case a short ventilation : . , tube or tubular projection 16, for example made of plastic, on which the filter 12 is then fitted. The filter element 13 can also be inserted into the short ventilation tube 16 (in the manner illustrated in Figure la). It is also, in ~;
principle, conceivable to attach the filter in the same way ~
~ ; ' ' ' . . . ' . ' ' . .: . ' . ", i ' ., . . ' 2 ~ 7 .

as depicted in Figure lb.
In the embodiments according to Figures 1 and 2 the filters are preferentially fitted so that the filter element 13 is flush with the outlet opening of the riser tube 11 or of the ventilation tube 16. It is also fundamentally possible to fit the filter element at a slight angle to the said tubes.
An integral type of construction is al60 in principle - -possible. In this case, the ventilation tube 16 shown in Figure 2 could be designed as a hydrophobic tubular part with an integrated filter element.
In the embodiment according to Figure 2 the air bubbles must pass through the liquid. In the case of high viscosity liquids it is not always certain that this will happen.
Therefore, in such cases the design shown in Figure 2 should ideally be used in pump-operated transfusion devices.
The filter materials preferentially used are the usual -~
plastic materials which are licensed for medical applications ~-~
or are certified as compatlble with foodstuffs. Hydrophobic, microporous membranes which are advantageously used to ventilate infusion solutions and which are used in infusion ~ -devioes are the materials of ahoioe. These membranes allow air to pass through under sterile conditions and they normally possess a mean pore size of 0.2-0.5 ~m.
The invention may be advantageously used as a transfusion device for bottles containing nutrient liquids - ~ -for tube feeding purposes. However, they may also be similarly used in infusion devices or in medication bottles ~ H

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS
Flgure 1 shows the es~ential parts of a transfusion device for a bottlé 1 filled with a mediaally active liquid ~
which is dispensed in a steady flow of drips, the bottle is --25 held in the inverted position. -The transfusion device is provided with a connector piece 3 adapted to fit the opening of the bottle, and having a flange section 4 engaging the edge of the bottle 2 and also provided with an opening 5 through which the liquid can pass.
The connector is integrally linked with a drip chamber 6 at the outlet l of which a tube 8 is attached for delivering the fluid to a patient. The further configuration of this delivery tube 8 is known and requires no further description here.
In order to ventilate the interior of the bottle when the liquid drains from it, the transfu~ion device is provided ;~
with an air duct 9 which opens into a short socket 10 in the flange section 4. A normally generally upright portion, in the embodiment shown, a ri~er tube 11, is fitted in this socket, and the upper end of the riser tube is closed by a hydrophobic filter 12. In the embodiment according to Fig. 1, ;`
the filter 12 is fitted over the riser tube 11. The filter 12 -consists of a filter housing with a filter element 1~, whose throughflow direction i6 coaxial with the axis of the rlser tube.
In an initial embodiment, the air duct 9 may advantageously be designed in such a way that it can be 20 closed on the air inlet side, e.g. by means of a pendant plug -~

In accordance with a further embodiment of the invention, as illustratad in Figure lb, the filter element 13 is fitted peripherally in the wall of a filter housing having the shape of an end cap, and the throughflow direction of the filter i8 perpendicular to the axis of the riser tube.
Thi~ latter configuration according to Figure lb permits unwanted liquid on the filter to drain off reliably after the riser tube has been immersed in the contents of the bottle.
Figure 2 depicts another possible configuration of a connector section of a transfusion device according to the invention. Parts which are identical with the embodiment lS illustrated in Figure 1 are identified by the same reference numbers.
In the configuration shown in Fig. 2, the hydrophobic filter 12 is fitted directly, i.e. without a riser tube, to the connector section 3. In principle, this could be done by ~-~
20 attaching the filter 12 directly to the normally generally -upright socket 10. However, it is more favourable to extend the air duct 9 by means of another type of a normally generally upright portion, in thi~ case a short ventilation : . , tube or tubular projection 16, for example made of plastic, on which the filter 12 is then fitted.

In the embodiments according to Figures 1 and 2 the filters are preferentially fitted so that the filter element 13 is flush with the outlet opening of the riser tube 11 or of the ventilation tube 16. It is also fundamentally possible to fit the filter element at a slight angle to the said tubes.
An integral type of construction is al60 in principle - -possible. In this case, the ventilation tube 16 shown in Figure 2 could be designed as a hydrophobic tubular part with an integrated filter element.
In the embodiment according to Figure 2 the air bubbles must pass through the liquid. In the case of high viscosity liquids it is not always certain that this will happen.
