Description
Technical field
This utility model relates to a kind of gynicologycal medical apparatus, specifically disposable two-chamber miscarriage pipet.
Background technology
Existing Double-lumen decompression aspiration tube for abortion is the structure of annulus cover annulus, for ensureing to attract the looped pipeline of this structure leading portion of effect to remove a part, because this pipe is the disposable technique extruded, tube wall is thinner again, the processing technique more complicated of follow-up removal looped pipeline, and percent defective is high; The cross section that looped pipeline is formed after removing, forms barrier, the attraction effect of impact supervisor; This structure causes the contact area of attraction and supervisor also can affect attraction effect comparatively greatly.
Utility model content
The purpose of this utility model is to provide disposable two-chamber miscarriage pipet, and this two-chamber miscarriage pipet simplifies technique, decreases rapidoprint while enhancing productivity, and reduces the circulating resistance of attraction, ensures that suction catheter attracts smoothness in use.
The technical scheme in the invention for solving the technical problem is: disposable two-chamber miscarriage pipet, its structure comprises supervisor and looped pipeline, described looped pipeline is arranged on supervisor's inner chamber, described supervisor one end is closed, other end opening, the blind end of supervisor is arc end, be provided with and the suction port be responsible for inner chamber and communicated in the side of supervisor's blind end, described looped pipeline is the discharge chamber that the dividing plate being circular arc by a cross section connects and composes with supervisor's inwall, described dividing plate one end is closed with the arc end of supervisor's inner chamber, the other end extends to the opening of supervisor's inner chamber and closes, on the sidewall of described supervisor, corresponding looped pipeline discharge chamber place is respectively equipped with steam vent and air inlet, described steam vent communicates with air inlet through the discharge chamber of looped pipeline.
Further, the opening of described supervisor is connected with handle, and described handle is hollow and two ends communicate, and supervisor's opening communicates with intracavity of handle.
Further, supervisor's inner chamber is divided into discharge chamber and attracts chamber by described dividing plate, and described discharge chamber and attraction chamber are two individual cavity.
Further, described supervisor and looped pipeline are that medical macromolecular materials are made.
The beneficial effects of the utility model are:
1, because this suction catheter adopts annulus to be nested with the structure of crescent looped pipeline, and one end of crescent looped pipeline is the blind end being responsible for inner chamber with circular ring type is directly tightly connected, the looped pipeline avoided in existing suction catheter needs many step operations to remove the part of looped pipeline leading portion in the course of processing, simplify processing technique, looped pipeline front section need not be removed again, enhance productivity; The looped pipeline leading portion that it also avoid existing structure on the other hand removes the rear barrier formed, and the contact area of attraction and supervisor is reduced, reduces circulating resistance, and attract smooth, attraction effect is better.
2, because the dividing plate of the looped pipeline employing circular arc in this suction catheter is divided into discharge chamber and attraction chamber supervisor's inner chamber, while guarantee attraction is effective, making material is also saved.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the top view of Fig. 1;
Fig. 3 is the upward view of Fig. 1;
Fig. 4 is sectional view of the present utility model.
In figure: 1 supervisor, 2 looped pipelines, 3 handles, 4 suction ports, 5 air inlets, 6 steam vents, 7 dividing plates.
Detailed description of the invention
With reference to Figure of description, disposable two-chamber miscarriage pipet of the present utility model is described in detail below.
As Fig. 1, Fig. 2, Fig. 3, shown in Fig. 4, disposable two-chamber miscarriage pipet of the present utility model, its structure comprises supervisor 1 and looped pipeline 2, described looped pipeline 2 is arranged on supervisor 1 inner chamber, described supervisor 1 one end is closed, other end opening, the blind end of supervisor is arc end, be provided with in the side of supervisor 1 blind end and the suction port 4 be responsible for inner chamber and communicated, described looped pipeline 2 is discharge chambers that the dividing plate 7 being circular arc by a cross section connects and composes with supervisor's inwall, described dividing plate 7 one end is closed with the arc end of supervisor's 1 inner chamber, the looped pipeline avoided in existing suction catheter needs many step operations to remove the part of looped pipeline leading portion in the course of processing, simplify processing technique, looped pipeline front section need not be removed again, enhance productivity, the other end extends to the opening of supervisor's inner chamber and closes, and on the sidewall of described supervisor 1, corresponding looped pipeline discharge chamber place is respectively equipped with steam vent 6 and air inlet 5, and described steam vent 6 communicates with air inlet 5 through the discharge chamber of looped pipeline 2.Be finally ensure pressure in patient uterine in attraction process by the effect of steam vent aerofluxus by the discharge chamber of air inlet, looped pipeline, reduce the misery of patient.Described supervisor and looped pipeline are that medical macromolecular materials are made.
Because the looped pipeline in this suction catheter just have employed, the dividing plate of circular arc realizes, so cost savings rapidoprint, reduces cost.
The opening of described supervisor 1 is connected with handle 3, and described handle 3 communicates for hollow and two ends, is responsible for 1 opening with handle 3 inner chamber to communicate, and handle free end connection negative pressure device, realizes vacuum suction.
Supervisor's inner chamber is divided into discharge chamber and attracts chamber by described dividing plate, and described discharge chamber and attraction chamber are two individual cavity.Because looped pipeline is the discharge chamber be connected to form with supervisor's inwall by dividing plate, the cross section of dividing plate is crescent, because attract the liquid of being not only also to be inconjunction with embryonal tissue through the suction port of supervisor front end in operation process, structure in the past makes attraction large at the circulating resistance of supervisor's inner chamber, easy blocking, attraction effect is bad, operating time is long, misery is brought to patient, and this meniscate dividing plate makes attraction and supervisor's lumen contact area reduce, circulating resistance is little, attracts smooth, shorten pull up time, decrease misery to patient.
The above, just explain through diagrams principles more of the present utility model, this description is not this utility model to be confined in shown described concrete structure and the scope of application, therefore every corresponding modify of being likely utilized and equivalent, all belong to the scope of the claims that this utility model is applied for.
Except technical characteristic described in description, all the other technical characteristics are those skilled in the art's known technology.
