Abstract
The invention discloses a suction head specially used for induced abortion operation. The suction head is a communicated pipeline and comprises a suction head top end, a catheter and a suction head tail part, wherein the suction head top end is inwards sunken, and a suction hole is formed in a sunken part; the suction head tail part is connected with a connection head; the other end of the connection head is connected with a negative pressure aspirator; an air inlet pipe is arranged on the catheter; an air inlet valve is arranged on the air inlet pipe. According to the novel suction head provided by the invention, the switchable air inlet valve and an expanded nut with a filter net are arranged at the tail end. The suction head is simple in structure, convenient to use, economical and practical; when the suction head gets into and gets out of a uterine cavity, the operation that a rubber pipe is repeatedly kneaded by an operator with a hand is avoided; tissues aspirated from the uterine cavity are directly taken out from the filter net, and the time of taking out a sample from a negative pressure aspirator bottle is saved; the whole operation is simple and quick.
Description
Technical field
The present invention relates to field of medical products, especially relate to a kind of medical operation suction nozzle.
Background technology
Known, department of obstetrics and gynecology during to the capable artificial abortion operation of women gestation, connect rubber tube with suction nozzle, and the other end of its rubber tube connects vacuum extractor.When sensation official jargon, dwindle gradually, palace wall is close to suction nozzle, represents that pregnant tissue exhausts, and now, takes off suction nozzle after needing first to clutch rubber tube with hands again, notices that each suction nozzle is not with negative pressure into and out of neck tube.Otherwise will cause the damage to cervical canal, cause the post-operative complication such as postoperative amenorrhea.Also organizing of sucking-off need be poured out from suction pump bottle, and after filtering with filter, ability inspection group's fabric also send pathologic finding.Complex operation.
Summary of the invention
in order to overcome the deficiency in background technology, the invention discloses a kind of medical operation suction nozzle.
In order to realize described goal of the invention, the present invention adopts following technical scheme: a kind of medical operation suction nozzle, and a pipeline for being connected, comprises suction nozzle top, conduit and suction nozzle afterbody; Suction nozzle top caves inward, and recess arranges sucker; Described suction nozzle afterbody is connected with union joint, and the other end of union joint connects vacuum extractor, on described conduit, air inlet pipe is set, and is installed into air valve in air inlet pipe.
Suction nozzle afterbody of the present invention is provided with drainage screen.
Drainage screen of the present invention is arranged in union joint, and union joint inside is provided with screw thread; Suction nozzle tailing screw flight is set on suction nozzle afterbody, and union joint is in mating connection by internal whorl and suction nozzle tailing screw flight.
Two parts before and after union joint of the present invention is divided into, front and rear is flexibly connected, and drainage screen is installed in junction.
Owing to having adopted technique scheme, the present invention has following beneficial effect: the invention provides a kind of novel suction nozzle, tail end is with intake valve that can switch, and with the union joint that expands of drainage screen.This sucker structure is simple, easy to use, economical and practical.When suction nozzle turnover uterine cavity, save with hands and repeatedly pinch rubber tube.In uterine cavity, the tissue of sucking-off directly takes out from filter screen, saves the time of taking out specimen from vacuum extractor bottle.Make whole operation simple, quick.
The head of suction nozzle is consistent with traditional artificial abortion's suction nozzle, and top is round and smooth, and the inside recess of arc has a slotted eye.Tail end first has an air intake valve, when suction nozzle turnover cervical canal, can open air intake valve, allows air enter, and cervical canal place does not have negative pressure, reduces intrauterine adhesion and damage.When inhaling intrauterine pregnant thing, valve closing, forms negative pressure.With the end of filter screen, can be thicker than the suction nozzle of front end, expand, inside there is filter screen, filter pregnant thing, the pregnant thing of sucking-off is filtered at this, screw is outwarded winding, and directly takes out from here, send pathologic finding after perusal.The tail end of union joint connects vacuum extractor.

The specific embodiment
Explanation the present invention that can be detailed by the following examples, discloses object of the present invention and is intended to protect all technological improvements in the scope of the invention.
The present invention includes suction nozzle top 1; Sucker 2; Conduit 3; Air inlet pipe 4; Intake valve 5; Suction nozzle tailing screw flight 6; Union joint 7, drainage screen 8.Described suction nozzle top 1 caves inward, and recess arranges sucker 2, and described suction nozzle afterbody is connected with union joint 7, and the other end of union joint 7 connects vacuum extractor, on described conduit 3, air inlet pipe 4 is set, and is installed into air valve 5 in air inlet pipe 4.Described suction nozzle afterbody is provided with drainage screen 8.Described drainage screen 8 is arranged in union joint 7, and union joint 7 inside are provided with screw thread; Suction nozzle tailing screw flight 6 is set on suction nozzle afterbody, and union joint 7 is in mating connection by internal whorl and suction nozzle tailing screw flight 6.Two parts before and after described union joint 7 is divided into, front and rear is flexibly connected, and drainage screen 8 is installed in junction.
During use, the tail end of union joint connects vacuum extractor.When suction nozzle turnover cervical canal, can open intake valve 5, allow air enter, cervical canal place does not have negative pressure, reduces intrauterine adhesion and damage.When intrauterine pregnant thing enters conduit 3 by sucker 2 from suction nozzle top 1, intake valve 5 cuts out, and forms negative pressure.Suction nozzle tail end, can be thicker than the suction nozzle of front end, expand, when sucking-off gestation thing, the pregnant thing of sucking-off is placed in drainage screen 8, and after operation, by union joint 7, therefrom portion is separately, by drainage screen 8, from the interior taking-up of union joint 7, pregnant thing directly takes out from here, send pathologic finding after perusal.After cleaning up, be arranged on union joint 7 in order to using next time.
Part not in the detailed description of the invention is prior art.
