Abstract

The utility model discloses a grid net isolation type anti-clogging negative pressure draining suction pipe which is composed of a suction pipe 1 and a suction pipe head 2, wherein a draining hole 5 wall is formed in the outer pipe wall of the suction pipe head 2; the suction pipe 1 is fixedly connected to the back end of the suction pipe head 2; an inflated grid net 3 is sheathed on the outer side of the suction pipe head 2; a communicating pipe 6 which is connected with an air pump is arranged on the inflated grid net 3, and the back end of the inflated grid net 3 is provided with an adhering ring 7 which is glued on the back neck section of the suction pipe head 2. In the grid net isolation type anti-clogging negative pressure draining suction pipe, because the inflated grid net is sheathed on the outer side of the suction pipe head, and the inflated grid net is made of thin films, when the utility model is inserted into an abdominal cavity, viscera are attached to the outer wall of the suction pipe head, and the surface is smooth, so the insertion is easy. When the grid net is expanded after being pressurized and inflated, the viscera separate from the outer wall of the suction pipe head, the draining hole can not be clogged, and the drain is fluent; thus, the utility model can not damage the viscera of the human body and can enhance the work efficiency of medical personnel.

Description

The isolated anti-blocking negative pressure drainage suction pipe of aperture plate

Technical field

This utility model relates to the improvement of negative-pressure drainage tube, belongs to a kind of medical apparatus and instruments, the isolated anti-blocking negative pressure drainage suction pipe of specifically a kind of aperture plate.

Background technology

At present, the negative pressure drainage art is widely used in abdominals such as abdominal surgery, and used depression drainage device mainly is made up of two parts now, and a part is the mechanical part that produces negative pressure, and a part is the drain suction pipe of imbitition.The present drain suction pipe of using clinically, comprise suction catheter and attract tube head, make of plastic tube mostly, it attracts the structure of tube head to be generally bushing type, pipe and outer tube promptly, interior pipe is positioned at the centre of outer tube, conduction hole is located on the wall of outer tube, suction catheter one end is sleeved on the rear end that attracts tube head, the other end connects negtive-pressure implement, liquid enters in the outer tube through the conduction hole on the outer tube wall, enters in the receiver of depression drainage device through interior pipe and suction catheter again, and the weak point of this drain suction pipe is: in abdominal, inhaling ascites, blood, during flushing liquor, omentum majus, intestinal tube, tripe tallow can be adsorbed on the outer tube wall, owing to attract to be in negative pressure state in the tube head, very easily makes in the conduction hole that the tissue of pressing close to and human internal organ be sucked into outer tube, result in blockage, influence normally carrying out of drain, if the excessive damage that also can cause the human abdominal cavity internal organs of captivation causes unnecessary damages to the patient.

Summary of the invention

The purpose of this utility model is existing drain suction pipe is improved, and a kind of isolated anti-blocking negative pressure drainage suction pipe of aperture plate that prevents that conduction hole from stopping up, avoiding damaging human internal organ, guarantee the work efficiency of normally carrying out, improve the medical worker of drain is provided.

For reaching above purpose, the technical scheme that this utility model adopted is: the isolated anti-blocking negative pressure drainage suction pipe of this aperture plate, constitute by suction catheter and attraction tube head, on the outer tube wall that attracts tube head, establish conduction hole, suction catheter is fixedlyed connected with the rear end that attracts tube head, it is characterized in that at the sheathed inflation aperture plate in the outside that attracts tube head, the inflation aperture plate is provided with the communicating pipe that is connected with air pump, be provided with the bonding ring in the rear end of inflation aperture plate, bonding is encircled the rear end neck portion that attracts tube head that is bonded in, and when attracting to carry out negative pressure drainage between tube head insertion internal organs, with air pump the inflation aperture plate is inflated, the inflation aperture plate is expanded, force internal organs to leave the outer tube that attracts tube head.This utility model is also implemented by following measure: described inflation aperture plate is by the thin film endless tube of vertical attraction tube head with along attracting the axial interlaced connection of straight film tube of tube head to constitute, be the grid tubular, the bonding ring of its rear end is the thin film ring, fixing by four diaphragms with the thin film endless tube bonding of the vertical attraction tube head of inflation aperture plate rear end, make the inflation aperture plate when the outer wall that attracts tube head is left in inflation, can not deviate to attract tube head, along attracting the axial straight film tube of tube head to establish the 6-8 root, vertically attract the thin film endless tube of tube head to establish the 6-8 ring.When using this utility model, will attract tube head to insert between internal organs, to the inflation of inflation aperture plate, the inflation aperture plate expands with air pump, leaves to attract the tube head outer wall, use the depression drainage device drain, treat that drain is finished after, discharge the gas in the inflation aperture plate, extraction attraction tube head gets final product.

The beneficial effects of the utility model are: compare with the negative-pressure drainage tube of present use since in the outside that attracts tube head sheathed inflation aperture plate, and the inflation aperture plate is made by thin film, so when inserting the abdominal cavity, be attached on the outer wall that attracts tube head, smooth surface is inserted easily, after the pressurization inflation makes inflation aperture plate rising, force internal organs to leave and attract the tube head outer wall, conduction hole can not stop up, and drain is unobstructed, human internal organ can be do not damaged, and medical worker's work efficiency can be improved.

The specific embodiment

Make this utility model with reference to accompanying drawing 1,3,4.The isolated anti-blocking negative pressure drainage suction pipe of this aperture plate, constitute by suction catheter 1 and attraction tube head 2, on the outer tube wall that attracts tube head 2, establish conduction hole 5, suction catheter 1 is fixedlyed connected with the rear end that attracts tube head 2, at the sheathed inflation aperture plate 3 in the outside that attracts tube head 2, inflation aperture plate 3 is provided with the communicating pipe 6 that is connected with air pump, be provided with bonding ring 7 in the rear end of inflation aperture plate 3, bonding ring 7 is bonded in the rear end neck portion that attracts tube head 2, when attracting to carry out negative pressure drainage between tube head 2 insertion internal organs, to 3 inflations of inflation aperture plate, force internal organs to leave the outer tube that attracts tube head 2 with air pump.Described inflation aperture plate 3 is by the thin film endless tube 3a of vertical attraction tube head 2 with along attracting the tube head 2 axial interlaced connections of straight film tube 3b to constitute, be the grid tubular, the bonding ring 7 of its rear end is the thin film ring, fixing by four diaphragms 4 with the thin film endless tube 3a bonding of the vertical attraction tube head 2 of inflation aperture plate 3 rear ends, along attracting tube head 2 axial straight film tube 3b to establish the 6-8 root, vertically attract the thin film endless tube 3a of tube head 2 to establish the 6-8 ring.
