Abstract

An induced abortion subpressure suction apparatus is provided, which relates to a medical instrument. When the utility model is used to repeatedly conduct the induced abortion operation, the uterine cavity is always isolated with the outside air, which guarantees the safety of the patients and is convenient in use and safe in operation. The utility model comprises a sucker and a subpressure injector and the sucker is connected with the subpressure injector. An intersecting line of a suction hole and a spatula is an arc mouth; a check valve is provided on the suction hole and a T-shaped handle is provided on the rear end of the piston pull rod of the subpressure injector. When the utility model is used to carry out the induced abortion uterine curettage and the subpressure injector needs to be changed, the check valve should be shut to avoid that the positive pressure air rinses the residue like blood in the uterine cavity into the abdominal cavity after entering the uterine cavity, which could become a hidden trouble causing the endometrium allotopia. The arc mouth between the spatula and the suction hole avoids that the spatula is broken in the uterine cavity during operation and danger occurs because of the stress concentration caused by the taper angle between the spatula and the suction hole. The T-shaped handle is arranged to make the operation accurate and convenient.

Description

Novel artificial miscarriage vacuum extractor

Technical field:

This utility model relates to a kind of medical apparatus and instruments.Particularly a kind of novel artificial miscarriage vacuum extractor.

Background technology:

Present artificial abortion operation, the vacuum extractor for artificial abortion of employing is; Vacuum artificial abortion's negative pressure catheter by negative pressure syringe that has check spring and minor diameter is formed by connecting through connection-peg, and it constitutes; Catheter proximal end is provided with inhales hole and spatula, the hole of its rear end and connection-peg is tight fit, be provided with annular convex rib behind the joint in the stomidium, be tight fit with the syringe front end, be provided with symmetric cavity in the piston handle vertically, constitute by the forward and backward plectane that is connected respectively of gusset, plate both sides, garden are provided with two parallel planes, its perpendicular bisector is divided angle between two gussets equally, plectane two parallel plane ends are the stiff end of clamping check spring respectively, check spring contracts and places in the cavity, and the front end of piston handle is provided with the piston that is sliding fit with the syringe endoporus.

Use this vacuum extractor for artificial abortion, at first conduit is inserted in the uterine cavity, along with the operation technique of scraping and inhaling of catheter proximal end suction hole and spatula, the pulling syringe, utilize the negative pressure of moving generation in the syringe behind the piston, with the embryonal tissue in the uterine cavity scrape and inhalation syringe in.After syringe is filled embryonal tissue, syringe is taken off from conduit, full thing is wherein outwelled, again syringe is connected with conduit again, repeat operation technique.

In the use of this vacuum extractor for artificial abortion, when operation needs repetitive operation, must be with syringe with after conduit separates, full thing in the syringe could be poured out, when taking off syringe, conduit communicates with air, owing to be negative pressure state in the conduit, extraneous positive pressure air then enters uterine cavity by conduit.After positive pressure air enters uterine cavity, residues such as uterine cavity inner blood are poured the abdominal cavity, become and cause endometriotic hidden danger.

Summary of the invention:

The present invention aims to provide a kind of novel artificial miscarriage vacuum extractor.When using this utility model to repeat artificial abortion operation, it is isolated that uterine cavity and outside air remain isolation, guaranteed patient's safety.And, easy to use, handling safety.

The technical solution of the utility model is;

It comprises suction pipe and negative pressure syringe, and suction pipe links to each other with the negative pressure syringe; Its suction pipe front end is provided with inhales hole and spatula, and the intersecting lens of inhaling hole and spatula is an arc port; On suction pipe, be provided with check-valves; The pitch brace rear end of negative pressure syringe is provided with T type handle.As Fig. 1, shown in Figure 2.

When using this utility model to implement artificial abortion operation, at first open the check-valves on the suction pipe, suction pipe is probeed in anemia of pregnant woman's the cavity of uterus, implement the dilatation and curettage, after embryonal tissue scrapes, utilize the negative pressure syringe with embryonal tissue's inhalation syringe.After in the negative pressure syringe, being full of embryonal tissue,, the negative pressure syringe is taken off, repeat after full thing wherein can being outwelled, also can exchange new negative pressure syringe for and repeat operation, finish until operation with the closure of check ring on the suction pipe.

This utility model in use, owing on suction pipe, be provided with check-valves, therefore, when operation needs repeatable operation, closing of check-valves makes when exchanging the negative pressure syringe for, keeps the state isolated with air in the uterine cavity, avoided because suction pipe when communicating with air, the positive pressure air in the external world enters the uterine cavity that is negative pressure state by conduit.After also having avoided positive pressure air to enter uterine cavity, residues such as uterine cavity inner blood are poured the abdominal cavity, become and cause endometriotic hidden danger.

Because the intersecting lens of suction of the present utility model hole and spatula is an arc port, therefore, in the operation of artificial abortion operation, can not produce stress concentration because of inhaling the wedge angle that exists between hole and the spatula, make that in the operation of dilatation and curettage, spatula fractures in uterine cavity, causes danger.

Because the T type handle of back end of tie rod setting of the present utility model makes that operation is more accurate, when having avoided spurring the negative pressure syringe piston in the operation, the phenomenon of the match slippage of living makes operation technique accurate, and is convenient.

In sum, when using this utility model to repeat artificial abortion operation, uterine cavity and isolate from outer air have guaranteed patient's safety.And, easy to use, handling safety.

Description of drawings:

Fig. 1 is a whole generalized section of the present utility model.

Fig. 2 is suction of the present utility model hole and spatula sketch map.

Among the figure:

The 1-suction pipe, 2-negative pressure syringe, the 3-spatula, 4-inhales the hole, the 5-arc port,

The 6-check-valves, 7-piston, 8-pull bar, 9-T type handle.

The specific embodiment:

Adopt external diameter Φ=6mm, the suction pipe 1 of internal diameter Φ=4mm is provided with spatula 3 at the front end of suction pipe 1, inhales hole 4, spatula with inhale formation arc port 5 between the hole, check-valves 6 is set on the suction pipe 1; The employing capacity is the negative pressure syringe 2 of 60ml, and the rear end at the pull bar 8 of the piston 7 of negative pressure syringe 2 is provided with T type handle 8.

When using this utility model to implement the artificial abortion dilatation and curettage, when negative pressure syringe 2 needs to change, check-valves 6 cuts out, to have avoided because suction pipe 1 when communicating with air, the positive pressure air in the external world enters the uterine cavity that is negative pressure state by suction pipe 1.After also having avoided positive pressure air to enter uterine cavity, residues such as uterine cavity inner blood are poured the abdominal cavity, become and cause endometriotic hidden danger.

The arc port that forms between spatula and the suction hole makes stress disperse, and has avoided because the wedge angle between spatula and the suction hole produces stress concentration, and spatula fractures in uterine cavity in the operation thereby make, and causes danger.

The setting of T type handle makes operation technique accurate, and is convenient.
