Description

2~13323 DEVICB FOR TR~T~ENT OF SI~SITID~S
The present invontion relatos generally to mo-dicino, more specifically to otDrhinolaryngology and has particular rs~eronce to a metbod for troat-m~nt of sinusitides.
Enown in tho art is a devico for treatment of sinusitidos, comprising an oblDng tubular body having tWD longitudinal passages. An infiatablo cuff is providod on said body botween its ends, and an in~latablo balloDn is lDcated at one of body ~nds. One of said longitudinal passagss i9 for air supply to the inflatablo balLoon, while tho other passago is for aspiratiDn of the pathologic contents and for administering medicinal agents. Tho other passage terminates bet;-Jean tho cuff and tbe balloon and communicatas, through its end Dpening, with the outside surface of the body (SU,A,1,311,714).
Whon applying tho aforssaid devico, tho inflatablo balloon and cuff are set in the choana and in the nasal vastibulo, respectively, in~lated so as to form an ~nclos~d space, and tb~ pathologic cDntents ars aspiratod through tho otber passa~o. How~ver, whon purulent or mucopurulent s~cr~tion passes along tho modian nasal passa~e and over ths ~ucosa to got into tho opening Df the socond longitudinal passag- of tho dcvico, part of th- contonts romains inovitably on the mucosal surface and may thero-foro got again intD tho sinuscs during subsequcnt administration of medicinal agents through the other passage of the housing. ~hat is wh~ trcatment with the aid of the aforediscussed device prov~s to be inadequa-tely effectual.
Said t~chnical problem is solved due to the fact that in a device for treatment of sinusitides, compri-sing an oblDng flexible tubular body, an in~latable cuff provided on the bod~ between its ends, and an inflatable baIloDn provided at one of tbe body ends and communi-cating with the first of two longitudinal passages provi-ded in the body, while the second passage terminates between the cuff and the balloon and communicates with the bodg surface through its end opening, according to the invention, a third passage is prDvided in the body, communicating with the outside body surface through an opening in tbe body side wall, said opening being lDcated betwee~ the end Dpening of the second passage and the inflatable balloon.
Said third passage enables one to wash tbe nasal cavities by feeding an irrigant to the posterior por-tions of the nasal cavity and by its simultaneous eva-cuation therefrom, which ensures removal of a part Df the pathDlDgic contents that has settled on the nassl mucosa, tbus adding to tbe efficacy of ~reat~ent of si-nusitides.
In what follows tbe invention is illustrated by a description of a specificj tbough not limiti~g, embodi-

3 2 ment o~ a device for treatment of sinusitides to be badwith reference to the acco~panying drawings, wherein:
~ IG. 1 is a sectiDnal view of a device for treatment of sinusitides, accDrdi~g to the inventiDn; and FIG. 2 is a device of FIG. 1 while insta~led in a patient.
Now referring tD tbe accompanying drawings, FIG. 1 presents the de~ice for treatment of sinusitides, which compri~es an oblong tubular bDd~ 1 ~ade of natural rubber and reinforced from inside with a hollow rod or a tube made of an elastic material 80 as to be a flexible struc-ture. The aforesaid bollow rod defines one of the pas-- sages.
A througb passage 3 i9 provided inside the body 1, ru~ning parallel to the hollow rod 2 and communicating with an inflatabLe balloon 4, provided st tbat e~d Df tbe bDdy 1 which is intended for insertion into the nasopbarynx, as it is best seen from FIG. 2. The pas-sage 3 communicates, at the opposite end, with an adapter 5 for introducing a syringe. The bollow rod 2 is stopped witb a plug 6 at one of its ends, wbile its opposite end extends from the bod~`1 and has an adapter 7 for a syringe (omitted in the Drawing). An opening 8 i9 provided in the side wall ~f the body 1 clDse tD the inflatable balloon 4 aimed at communicating tbe bore of the bollow rod 2 with the outside surface o~ tbe bod~ 1. Tne body 1 bas a sbort tubular segment 9 estab-lishing a passage 10 having an end Dpening 11 that co~-municates with the outside surface of the passage 10. A
cuff 12 i8 prDvided between tbe ends of the body 1 in the zone cf the tubular segment 9 said cuf~ com~lunicati~g with an air source through its own tube 13.
~ reatment with the aforedescribed device is carried out as fDllDws.
once the affected nasal passage has been anesthe-tized and dehematized with a 2-percent Dicaine (tetracaine hydrochloride) solution doped with an Adrenlalin (ep~ep-hrine) solution (one drop of 0.1-percent Adrenalin per milliliter of 2-percent Dicaine), the nasal passage is to be clear.ed by blowin patient's nDse. Then the de-vice is inserted into -~he nsal cavity through the infe-rior seg~ent Df the commDn nasal meatus as far as tbe nasopharynx.
While so doing the inflatable balloon 4 i9 passed, in a deflated state, as far as tbe choana, while the cuff 12 is passed along tbe body 1-and introduced inbo the vestibule of the nose in accordance with the indi-vidual dimensiDns of the com~Dn ~asal meatus Df a pa-tient. Next the balloon 4 and the cuff 12 are i~flated, thus obstructing the cavity, whereupon the corresponding adapters are stDpped with their respective plugs. After that a 20-ml syringe or the nozzle Df an electric as-piratDr (omitted in the Drawing) is connected to an adapter 14 of tbe passa~e 10. Then a negative pressure of 0.4 , to 0.6 atm is established in the nasal cavity, whareby the pathDlogic contents are urged to pass from the para-nasal sinuses into the rarefied space tD be sucked into the syringe or the receptacle o~ an electric aspirator.
As soon as t~e negative pressure thus built up results no longer in admission of the pathologic secretion into the syringe or tbe elactric aspiratDr receptacle, a syrin-ge filled with an antiseptic solution is connected tD
the adapter 7 of tbe ~ube 2. The antiseptic is injected through the bollow rod or the tube ~ simultaneousl~
with building-up a negative pressure in the nasal cavity through the passage 10. Such irrigation resuLts in final evacuation of purulent or mucopurulent secretiDn from ths nasal cavity. The fact that the li~uid passes through the nasal cavity fro~ behind for~ard and that a negative pressure i8 created simultaneously, contributes to a higher aspiration efficienc~, since the effect of a water-jet pump is added tD that o-f a negative pressure.
It is worth notinO that aspiration and irrigation are performed witb the patient in the sitting posture, his/her head inclined ta the side opposite to tbat of tbe affected nasal passage Once the lavage has been compLeted, which is evi-denced b~ evacuation of the antiseptic solution free from foreign admixtures, ~e patient is to be put in a lateral position witb his/her head drooping to the side vf the affected nasal cavity and a medicinal sub-o stance is adminiqtered to the paranasal sinuses with theaid of any known technigue.
~ hus, the herein-proposed metbod for treatLent of sinusitides and a device ~or carrying ssid method into ef~ect make it pDssible to completely evacuate pathologic contents from the nasal cavity, thus preventing said contents from returning into tbe paranasal sinuses and contributing to a higher efficiency of the therapy of sinusitis.
