Description

A kind of irrigation drainage tube

Technical field

This utility model relates to a kind of irrigation drainage tube, and the device especially for surgery flushing and drain, belong to medical instruments field.

Background technology

Surgical drainage is the requisite measures of a lot of diseases of clinical treatment, for example drain in anastomotic stoma He Shu district after the operation, the drain of abscess cavity etc.Drainage tube commonly used is mainly a single pipeline at present, is passive drain, and the factor impacts such as poor and position that are stressed, inadequate drainage often occurs, and easily causes body fluid to accumulate; And only a passage, can not meet the demands such as drug injection, flushing, drain simultaneously, the problem of the aspects such as inconvenience often appears infecting, using.

Summary of the invention

For overcoming above-mentioned the deficiencies in the prior art, this utility model provides a kind of Novel flushing catheter, it comprises drainage tube 1 and syringe pipe 2 twin flues, the section of tubing of syringe pipe 2 is arranged in drainage tube 1, stretch out from drainage tube 1 at syringe pipe 2 two ends, but and the front end length free adjustment of syringe pipe 2; Drainage tube 1 front end tube wall top and side with interval, the asymmetrically distributed conduction hole 3 that interlocks (conduction hole 3 do not design below, avoid drainage-fluid to be spilt by the tube wall below, be conducive to abundant drain), drainage tube 1 pipe inner bottom part is with the ridge 4 of 2-3 bar projection, negative pressure is excessive while causing tube chamber to dwindle, can avoid tube chamber to entirely shut.

Drainage tube 1 tail end described in the utility model is with the joint be connected with negative pressure device, and drainage tube is made with silastometer or silastic material, and zest is little, and the drain scope is enough large, and tail end connects continuous negative pressure.

Syringe pipe 2 tail ends described in the utility model are with the joint be connected with flushing liquor.

The tail end of drainage tube described in the utility model connects continuous negative pressure, and the tail end of syringe pipe connects the continual rinsing device, continues to provide flushing liquor.

During use, syringe pipe one end opening, in focus (art district, anastomotic stoma, fistula mouth etc.) top, is injected to flushing liquor from syringe pipe other end joint, guarantee that the flushing scope enough covers whole focus zone; Continue to inject peritoneal lavage fluid or medicine through syringe pipe during use, be rinsed slough that liquid rinses through the drainage tube front end and on conduction hole introduce tube chamber, by negative pressure, drawn, drain is abundant, easy to use, can effectively avoid, reduce the generation of infection.

Compared with prior art, the beneficial effects of the utility model are:

1. can carry out continual rinsing and carry out negative pressure drainage abdominal cavity;

2. can adjust duct length according to size of tumor, one end of syringe pipe is placed in the focus top, and the flushing scope is wide, and the intracorporeal indwelling time is long, can cover whole focus (art district, anastomotic stoma, fistula mouth etc.), the sustainable injection flushing liquor of the other end, antibiotic or medicine; The drain scope of drainage tube contains whole focus, can connect negative pressure and continue attract, and drain is abundant, and the obstruction of tube chamber has been avoided in the design of conduction hole and the mouth of pipe, and, owing to rinsing and drain is carried out through different pipelines, has reduced infection rate;

3. this apparatus structure is simple, easy to use, economical and practical; Can carry out as required drug irrigation drain, simple drain or simple drug injection, but effective drainage art district oozing of blood promotes focus, anastomotic healing, observation, prevention and treatment fistula of operative incision, prevent that the art district from infecting, and clinical practice is extensive;

4. the clinical scope of application is as follows:

1. for observing, prevent and treat gastrointestinal tract fistula of operative incision, leak, pancreas fistula;

2. limitation, diffuse peritonitis;

3. peritoneal abscess, liver abscess and soft tissue, pancreatic cyst, cystic Tumor of Pancreas etc.

The specific embodiment

Below in conjunction with drawings and Examples, this utility model is described in further detail, but protection domain of the present utility model is not limited to described content.

Embodiment 1: this utility model irrigation drainage tube comprises drainage tube 1 and syringe pipe 2 twin flues, wherein rinses pipe range 50cm, external diameter 2.6 ± 0.1mm, and internal diameter 2.0 ± 0.1mm, two ends are unobstructed; Drain pipe range 100cm, external diameter 7.0 ± 0.2mm, internal diameter 6.0 ± 0.2mm; The section of tubing of syringe pipe 2 is arranged in drainage tube 1, and stretch out from drainage tube 1 at syringe pipe 2 two ends, and two pipelines are " π " type, but and the front end length free adjustment of syringe pipe 2; Drainage tube 1 front end tube wall top and the staggered mal-distribution in side have conduction hole 3; Every 1cm, a 2mm size conduction hole (the excessive easy suction tissue in aperture causes obstruction) is arranged, for extracting liquid, conduction hole interval, side, be interspersed in the drainage tube both sides, do not line up that (negative pressure is difficult for leaking outside, the drain scope is wide, and drain is more abundant); Drainage tube pipe inner bottom part is with the ridge 4 of 2 projections, negative pressure is excessive while causing tube chamber to dwindle, can avoid tube chamber to entirely shut; Drainage tube head length is according to needing the drain range size to determine, cover whole focus, drainage tube front end shape is as shown in Fig. 3,5, can effectively avoid stopping up, the drain scope is also wide than plane, and drainage tube is made with the silicon moulding material, and the drainage tube tail end has the joint be connected with negative pressure device 7, the syringe pipe tail end has the joint be connected with flushing liquor 8, sustainable injection flushing liquor (seeing Fig. 1-4).
