Abstract
ASPIRATE RECEIVER
Abstract of the Disclosure The aspirate receiver comprises a bowl with a cap. The interior of the bowl communicates with a source of vacuum and is connected, via a through hole in the caps to an aspi-ration tip. The bowl with the cap is accommodated in a hous-ing with a cover concentrically with said housing. An annular gap is established between an inner wall of the housing and an outer wall of the bowl, said gap communicating with a source of vacuum. The through hole in the bowl cap is coaxial with the annular gap. The cover of the housing is provided with a sleeve. One end of the sleeve is adapted for connect-ion to the proximal end of the aspiration tip, while the other end of the sleeve facing inwards the housing is arrang-ed coaxially with the hole in the bowl cap and is encompass-ed by said bowl.

The known device is also disadvantageous in that the cylindrical meshy element is difficult to be cleaned of the solid aspirate particles stuck thereto.
Besides, when being removed from the cylindrical element such particles are damaged, which interferes with their subsequent histological examination.
It is an object of the invention to provide an aspirate receiver whose application makes it possible to contain the entire aspirate obtained in the course of vacuum aspiration of the uterine contents and to make an individual quantitative and qualitative analysis of the aspirate collected.
It is another object of the invention to cut down the time spent for postoperative bowl treatment in order to ensure uninterrupted operation of the aspirate receiver.
The foregoing object is accomplished by an aspirate receiver comprising:
a) an aspirate collecting bowl provided with a cap and defining a longitudinal axis;
the bowl comprisinq a bottom and a wall having an inner and an outer surface and defining an interior;
said interior of said bowl communicating with a source of vacuum and receiving an aspirate;
b) a through hole in said cap of said bowl;
the cap preventing arbitrary decantation and interacting with the inner surface of said bowl;
c) a hollow housing provided with a cover and defining an interior, accommodatinq concentrically said bowl with said cap;
said housing and said cover comprising a wall having an inner and an outer surface to isolate said interior from the environment;
d) a through hole in said housing in communication with said vacuum source;

f) an annular space defined between the inner wall surface of said housing and cover and the outer wall surface of said bowl, said space concentric with said through hole in said cap, with said space communicating with said source of vacuum.
More specifically the aspirate receiver comprises, a bowl provided with a cap, the interior of said bowl communicating with a source of vacuum and being .
connected, via a through hole in the bowl cap, to an aspiration tip, according to the invention, the bowl with the cap is accommodated in a housing provided with a cover and arranged concentrically with the housing so that an annular gap is established between the housing inner wall surface and the bowl outer wall surface, said gap communicating with a source of vacuum, while the through hole in the bowl cap is concentric with the annular gap, and the housing cover is provided with a sleeve whose one end is adapted for connection to the proximal end of the aspiration tip, while the other sleeve end, facing the housing inwards, is arranged coaxially with the hole in the bowl cap and is -enveloped by said bowl. ~

_ 4 _ 1328389 Such a construction arrangement of the aspirate receiver makes it possible to collect the sspirate resulting from tho surgery performed, completely and ~ithout 1089. This in turn ensbles one to effect its quantitsti~e and qualitative snaly-sis w$thout delay.
Such sn embodiment of the aspi~a~o receiver pre~Qnts the aepirste from getting into the co~mecting sleme~t~ and the va-cuum ~ystem elements, whi¢h is of great importance in AIDS
preYention, since it svolds any propagation of the infection contained in blood stains and spla~he~ and coagulated blood clots depo3ited upon the connecting elements whi¢h are hard--of-~¢oe~& for postoperstive treatment.
In addition, the bowl of the herein-proposed sspirstor re¢eiver i~ e~y-to-withdrsw from the housing, it is readily and rapidly di~infected, after which the bowl is resdy to use aBain without any danger of infection propagation. This ¢ut~ down the postoperati~e bowl treatment time, thus en~ur-ing uninterrupted operation of the aspirate receiver.
It i~ also e~pedient that the clear passage area of the sleeYe end,adapted to communi¢ate with the pro~im~l end of the aspiration tip,be in ex¢ess of the clear passage area of the sl~eve e~d facing the housing interior.
Su¢h a ¢onstru¢tion arrangement of the sleeve favours proper holding o~ the aspiration tip and prevent~ the aspirate irom ~plashing oYor the bowl inner walls, ~hich enables one to collect tho aspirate result~nt rrom tho ~urgery without 1088.

Claims (2)
1. An aspirate receiver comprising:
a) an aspirate collecting bowl provided with a cap and defining a longitudinal axis;
the bowl comprising a bottom and a wall having an inner and an outer surface and defining an interior;
said interior of said bowl communicating with a source of vacuum and receiving an aspirate;
b) a through hole in said cap of said bowl;
the cap preventing arbitrary decantation and interacting with the inner surface of said bowl;
c) a hollow housing provided with a cover and defining an interior, accommodating concentrically said bowl with said cap;
said housing and said cover comprising a wall having an inner and an outer surface to isolate said interior from the environment;
d) a through hole in said housing in communication with said vacuum source;
e) a sleeve of said housing cover arranged on said bowl coaxially with the longitudinal axis of said cap and having a distal end and a proximal end;
said distal end adapted for connection of an aspiration tip, and said proximal end facing the housing inwardly and coaxially with said through hole in said cap;
f) an annular space defined between the inner wall surface of said housing and cover and the outer wall surface of said bowl, said space concentric with said through hole in said cap, with said space communicating with said source of vacuum.
a) an aspirate collecting bowl provided with a cap and defining a longitudinal axis;
the bowl comprising a bottom and a wall having an inner and an outer surface and defining an interior;
said interior of said bowl communicating with a source of vacuum and receiving an aspirate;
b) a through hole in said cap of said bowl;
the cap preventing arbitrary decantation and interacting with the inner surface of said bowl;
c) a hollow housing provided with a cover and defining an interior, accommodating concentrically said bowl with said cap;
said housing and said cover comprising a wall having an inner and an outer surface to isolate said interior from the environment;
d) a through hole in said housing in communication with said vacuum source;
e) a sleeve of said housing cover arranged on said bowl coaxially with the longitudinal axis of said cap and having a distal end and a proximal end;
said distal end adapted for connection of an aspiration tip, and said proximal end facing the housing inwardly and coaxially with said through hole in said cap;
f) an annular space defined between the inner wall surface of said housing and cover and the outer wall surface of said bowl, said space concentric with said through hole in said cap, with said space communicating with said source of vacuum.
2. An aspirate receiver as set forth in claim 1 in which a cross-sectional area of said distal end of said sleeve intended for connection with the aspiration tip, is greater than said cross-sectional area of proximal end of said sleeve.
