Abstract

The invention provides negative pressure drainage apparatus and belongs to the technical field of medical apparatus. The negative pressure drainage apparatus comprises a silicone air bag, a transition tube and drainage tube, wherein an air bag seal cover is combined on the top of the silicone air bag, and a liquid inlet connector and a liquid discharge connector communicated with a bag cavity of the silicone air bag are arranged on the air bag seal cover. A plug cover belt is sleeved on the liquid inlet connector, and a plug cover is arranged on the plug cover belt. The plug cover is matched with the liquid discharge connector, and one end of the transition tube is connected with the liquid inlet connector. The other end of the transition tube is connected with the drainage tube, and a tube clip is arranged on the transition tube in a matched mode. The cross section of the drainage tube is in a rectangle shape, and liquid gathering holes are formed in opposite wall bodies of the drainage tube in the width direction. The liquid gathering holes correspond to each other in positions, and are communicated with a drainage tube cavity of the drainage tube. The negative pressure drainage apparatus has the advantages of having effects of being labor-saving and quick in operation, being convenient to manufacture, and low in cost, and capable of showing multichannel drainage, and shortening drainage time of a patient.

Description

Depression drainage device

Technical field

The invention belongs to the medical devices technical field, be specifically related to a kind of depression drainage device

Background technology

Depression drainage device is mainly used in the postoperative drain of puncturing to thoracic cavity, abdominal cavity patient, in patent documentation, have been reported, the multi-functional Thoracicoabdominal puncture depression drainage device of typically recommending such as CN2782100Y, consisted of by tee T, drainage tube and negative pressure drainage container (patent claims depression drainage device), because the negative pressure drainage container of this patent is simple gauffer body structure, therefore can expose following technical problem in use: when the air in the negative pressure drainage container is displaced be in receive flat state after, namely be in the anxiety that often has the diastole difficulty after the negative pressure state.In addition, because inlet and outage on the depression drainage device of this patent are separately positioned on upper surface and lower surface, more precisely, be positioned at the lower surface of depression drainage device because of outage, therefore have the risk of leaking.

The Thoracentesis negative pressure drainage device that utility model patent Granted publication CN2848232Y provides, it is to be equipped with spring in the negative pressure drainage container, and the negative pressure drainage vessel still remains the gauffer body; The Medical thorax puncture negative pressure drainage that utility model patent Granted publication CN201064579Y discloses is in the negative pressure drainage container spring to be set equally, and changes the negative pressure drainage vessel into non-wrinkled body.In these two patents, the former structure is inferior to the latter, because the structure of gauffer body can increase the active force of spring to a great extent unnecessaryly.The common shortcoming of these two patents is: comparatively require great effort during air in driveing the negative pressure drainage container; Make very trouble, because in manufacture process, need spring is set in the cavity volume of negative pressure drainage container.Particularly, drainage way is owing to being that single-point type is the single channel drain, thereby the drain process is tediously long, is unfavorable for shortening the treatment time to the puncture patient.Aforesaid single channel drain refers in the patient body to be that thoracic cavity or Intraabdominal hydrops can only be drawn by a unique passage.

In view of this, be necessary to be improved, so the applicant done positive trial, the below produces the technical scheme of face introduction under this background

Summary of the invention

Task of the present invention be to provide a kind of rapid operation and quick, make easily and help to significantly improve drainage speed and use the depression drainage device that shortens patient's drainage time.

Task of the present invention is finished like this, a kind of depression drainage device, comprise a silica gel air bag, the top of this silica gel air bag is combined with air sac sealing lid, cover at this air sac sealing and to have the feed liquor interface that communicates with the blister cavities of silica gel air bag and a discharge opeing interface, and be arranged with a gag band at the feed liquor interface, have a gag at the gag band, gag matches with described discharge opeing interface; One transition conduit and a drainage tube, one end of transition conduit is connected with described feed liquor interface, the other end is connected with drainage tube, and be equipped with a pipe clamp in transition conduit, the shape of cross section of described drainage tube is rectangular, offers remittance liquid that the position corresponds to each other and that communicate with the drainage tube chamber of drainage tube hole at the aspectant wall body of the width of this drainage tube.

Silica gel air bag of the present invention is transparent, and is provided with gage mark at outer wall.

Being fixed with one between silica gel air bag of the present invention and the described air sac sealing lid is linked with.

Of the present invention being linked with is provided with a clip.

Therefore technical scheme provided by the invention can hold the air of pinching in the blister cavities by one hand and displace from exhaust port owing to having adopted the silica gel air bag, has rapid operation and effect efficiently; Use spring owing to need not to resemble the prior art, therefore easy to make and cheap; Because drainage tube is being designed to the rectangular thallus of shape of cross section structure and is being provided with at the aspectant wall body of the width of drainage tube to converge the liquid hole, so can show the multichannel drain, shortening is to patient's drainage time densely coveredly.

Description of drawings

Fig. 1 is the embodiments of the invention structure chart.

Fig. 2 is the cross sectional representation of drainage tube of the present invention.

The specific embodiment

Ask for an interview Fig. 1 and Fig. 2, provided shape just as the goose egg shape and material be the silica gel air bag 1 of silicone rubber, be installed with air sac sealing lid 11 at the top of this silica gel air bag 1 and by means of being located at the trim ring in the blister cavities, consisting of at this air sac sealing lid 11 has feed liquor interface 111 and a discharge opeing interface 112 that communicates with blister cavities.Be equipped with a gag band 4 at feed liquor interface 111, have a gag 41 on the gag band 4, this gag 41 matches with aforesaid discharge opeing interface 112.In addition, be provided with gage mark 12 at the outer wall of transparent silica gel air bag 1, and between silica gel air bag 1 and air sac sealing lid 11, be fixed with one and be linked with 13, be equipped with a clip 131 being linked with 13.

One end and the feed liquor interface 111 of one transition conduit 2 connect, and the other end is connected with drainage tube 3, also is equipped with a pipe clamp 21 on transition conduit 2.Shown in figure, drainage tube 3 is flat rectangular shape, on the aspectant wall body of the width of drainage tube 3, also namely on the upper lower wall of shown position state, offer thick and fast the hole 32 of confluxing that the position corresponds to each other and that communicate with drainage tube tube chamber 31.

After thoracic cavity or abdominal operation were finished, drainage tube 3 was placed in patient's the breast or abdomen, by the remittance liquid hole 32 on it hydrops in breast/abdominal cavity was imported drainage tube chamber 31, introduced in the blister cavities of silica gel air bags 1 through liquid pipe 2 and feed liquor interface 111.In the time of drainage-fluid in the blister cavities need being fallen remove behind the full liquid, open so gag 41 and get final product.

In sum, scheme provided by the invention has overcome the deficiency in the prior art, has finished the invention task, has embodied the described technique effect of applicant
