Abstract

FIELD: medicine.

SUBSTANCE: invention refers to abdominal surgery, and can be used for abdominal drainage in order to prevent postoperative complications. Device for abdominal drainage represents an antireflux device and consists of silicone tube 420 mm in length, distal end of which has 3 side holes with diameter of 3 mm, located at distance of 3 mm from each other, opposite to the second opening at distance of 10 mm from the distal end, an irrigation port with diameter of 2 mm is opened. At distance of 30 mm from the distal end of the tube, the device is equipped with a pneumatic reservoir, and on the proximal end of the tube there is a drain channel provided with an automatic valve, an irrigation port and a port for filling the pneumatic reservoir.

EFFECT: using the invention enables excluding contact of the external environment and the abdominal cavity in the postoperative period, as well as providing an effective drainage function.

Description

The device relates to medicine, namely to abdominal surgery and can be used for drainage of the abdominal cavity in order to prevent postoperative complications.

Analog

Known drainage tube made of silicone at the distal end of which there are side holes.

Criticism of analogues

1. In a short time, the side holes are blocked with blood clots, fibrin, or omentum.

2. Early drainage dysfunction.

3. Two-way movement of exudate through the drainage, both from the abdominal and the abdominal cavity of the infected fluid leads to a hospital infection in the abdominal cavity from the external environment.

4. Migration of drainage from the drainage area.

5. The impossibility of reactivating the drainage function of drainage, in order to prolong the drainage period.

Prototype.

For drainage of the gastrointestinal tract, the Salem tube anti-reflux device is used with anti-reflux valve.

1. Has two channels, one for suction drain and the other for washing.

2. At the proximal end there is an anti-reflux valve.

3. There is a radiopaque line throughout the drainage.

4. This device is used for installation in the stomach.

5. Has a length of 91-122 cm.

Criticism of the prototype.

1. This device is a prototype is not intended for installation in the abdominal cavity.

2. The diameter of the lumen is insufficient for effective drainage.

3. The impossibility of reactivating the drainage function.

Purpose of the invention

The aim of the invention is to develop a device for drainage, eliminating the contact of the external environment and the abdominal cavity in the postoperative period, as well as having an effective drainage function.

Summary of Invention

The device is illustrated in FIG. 1, where pos. 1 - automatic valve; pos. 2 - port for irrigation of the drainable cavity; pos. 3 - drainage channel; pos. 4 - port for filling the pneumatic reservoir; pos. 5 - pneumatic tank.

The essence of the proposed device is that after operations on the abdominal organs, a drainage device is supplied to the drainage zone, consisting of a drainage channel (Fig. 1 pos. 3) at the distal end of which there is a pneumatic tank (Fig. 1 Pos. 5), which is filled with air through the port for filling the pneumatic tank (Fig. 1, pos. 4), and at the proximal end, an automatic valve (Fig. 1, pos. 1). The device also has a port for irrigation of the drainable cavity (Fig. 1 pos. 2). The automatic valve functions due to the pressure difference in the abdominal cavity and the external environment.

The features of the invention, the distinctive features of the prototype.

1. The distal part of the drainage tube is equipped with a pneumatic reservoir.

2. The proximal part of the drainage has an automatic valve.

3. The distal end of the tube has 3 lateral holes with a diameter of 3 mm., Located at a distance of 3 mm. from each other, opposite the second hole at a distance of 10 mm. from the distal end opens a port for irrigation with a diameter of 2 mm.,

4. The device is intended for drainage of the abdominal cavity.

5. The length is 420 mm.

6. The diameter of the lumen contributes to effective drainage.

Technical effect

The invention provides the ability to reactivate the drainage function online throughout the postoperative period.

The device has a pneumatic reservoir, which inflating and blowing out allows you to change the volume of the surrounding space online, which allows you to separate loose adhesions, empty residual liquid formations or fluid accumulation, free side drainage holes from occluding organs and tissues, provides compression hemostasis, eliminates migration from the drainage zone .

At the outer end of the device there is an automatic valve, which allows to ensure the outflow of fluid only from the distal to the proximal part, i.e. drainage evacuates the contents of the abdominal cavity through the lumen only to the outside, preventing back into the abdominal cavity, which significantly increases the volume of evacuated fluid from the cavity to the outside, and thus increases the efficiency of drainage, while reducing the likelihood of abdominal re-infection. This device has an irrigation port that allows flushing the cavity around the installation area of the device.

Claims (1)

A device for drainage of the abdominal cavity, which is an anti-reflux device, characterized in that it consists of a silicone tube 420 mm long, the distal end of which has 3 lateral holes 3 mm in diameter, spaced 3 mm from each other, opposite the second hole at a distance of 10 mm from the distal end opens a port for irrigation with a diameter of 2 mm, at a distance of 30 mm from the distal end of the tube, the device is equipped with a pneumatic reservoir, and at the proximal end of the tube there is a drainage channel, nabzhenny automatic valve for irrigation port and a port for filling the air reservoir.
