Abstract

The invention discloses a disposable negative-pressure drainage device, relates to a drainage device and in particular relates to a drainage device used for draining out drainage fluid after the abdomen, the neck and the body incision are operated. The disposable negative-pressure drainage device can be used for solving the problems of poor drainage effect, high possibility of polluting the incision and poor precaution effect when the traditional drainage mode is used for preventing operative incision liquefaction and infection. The disposable negative-pressure drainage device comprises a syringe and a drainage tube, wherein one end of the drainage tube is hermetically connected with the syringe needle end of the hollow barrel of the syringe; and the tube wall of the other end of the drainage tube is provided with a plurality of holes. The drainage fluid is guided out by negative pressure in the disposable negative-pressure drainage device, bacteria can be prevented from invading inward from the outside, the incision has small possibility of being polluted, the drainage effect is good, the possibility of adsorbing heat after the operation is lowered, and the effect on the aspect of preventing the abdomen, neck and body operative incision liquefaction and infection is good. The disposable negative-pressure drainage device has a simple structure, is convenient to use and is used for preventing the operative incision liquefaction and infection.

Description

Disposable depression drainage device

Technical field

The present invention relates to a kind of drainage device, relate in particular to a kind of drainage device that the drain liquid of abdominal part, cervical region and trunk otch postoperative is drawn of being used for, belong to medical instruments field.

Background technology

Operative incision liquefaction, infection are the problems that often runs in the clinical operation, and very thorny, cause patient's hospital stays to prolong; Medical expense increases, and the prevention key of operative incision liquefaction, infection is to handle early and fully drain, but traditional drainage way such as drain of rubber bar; Exist drainage effect poor, draw liquid and be prone to contamination of incision, be difficult for nursing; Be difficult for long-time the use; Operation back is sewed up and easily the rubber bar is sewed in addition, phenomenon such as causes difficulty occurring extracting, pull off, and brings sense of discomfort to patient's body.

Summary of the invention

The objective of the invention is prevention, having that drainage effect is poor, otch is prone to pollute and the problem of preventive effect difference, and then a kind of disposable depression drainage device is provided for solve adopting traditional drainage way to be used for operative incision liquefaction, to infect.

The present invention addresses the above problem the technical scheme of taking to be: disposable depression drainage device of the present invention comprises syringe and drainage tube, and the needle end of the empty tube of an end of drainage tube and syringe is tightly connected, and offers a plurality of holes on the other end tube wall of drainage tube.

The invention has the beneficial effects as follows: 1, the present invention adopts negative pressure to derive and draws liquid; Avoided the invasion of antibacterial ecto-entad, otch is difficult for polluting, and drainage effect is good; Reduce postoperative and absorbed hot generation, effective aspect prevention abdominal part, cervical region and the liquefaction of trunk operative incision, infection; 2, offer a plurality of holes on the drainage tube, increase the drain area, improve drainage effect; 3, the present invention is simple in structure, and is easy to use, can be in hospital application at different levels; 4, the present invention uses through 2200 routine patients (comprise diabetics, big otch patient such as cancer operation, secondary or patient with operation repeatedly, operating time is greater than 3 hours patients and gerontal patient), fact proved that the wound healing rate is 100%; 5, the present invention creates 2,800,000 yuan of economic benefits through practical application.
