Description

Technical Field

[0001] The utility model relates to the technical field of abdominal cavity drainage tubes, in particular to a suture-free and leakage-proof abdominal cavity drainage tube. Background Art

[0002] As the name suggests, a peritoneal drainage tube is a tube placed inside the abdominal cavity. Its function is drainage. Of course, there are many types of drainage materials. Generally, the most commonly used is intra-abdominal blood. Peritoneal drainage tubes are generally used after abdominal surgery to drain bleeding, exudate and other drainage fluids from the wound or incision, and to observe intra-abdominal bleeding and exudate, judge the condition of the incision after surgery, and the patient's recovery.

[0003] The abdominal drainage tubes currently used in clinical practice have the following defects:

[0004] 1. When fixing the abdominal drainage tube, one or two stitches are made on the skin next to the tube, and then the sutures are tied to the drainage tube. However, this suture has several disadvantages: (1) The drainage tube often pulls the skin through the sutures, causing obvious local pain. In particular, many surgeons have never recognized this problem due to lack of technical skills, or they rush the operation in pursuit of speed. When tying the knot, the sutures of the abdominal drainage tube are too tight, causing some patients to experience unbearable severe pain, affecting postoperative recovery and quality of life. (2) In addition, for some patients whose condition persists or progresses and the tube cannot be removed in a short period of time, long-term traction will cause skin ischemia and necrosis, and then the sutures will loosen or fall off, requiring re-suturing or even repeated suturing, resulting in local tissue damage and inflammatory infection, eventually forming a vicious cycle and further increasing the patient's pain. (3) Sometimes, too little skin tissue is sutured or the suture time is too long, causing the sutures to loosen. If not paid attention to, such as when sleeping at night, it may cause the drainage tube to completely fall out or be accidentally pulled out by the patient himself.

[0005] 2. After peritoneal catheterization, some patients experience peritoneal fluid effusion during drainage due to relaxation of the abdominal wall soft tissue, which leaks out of the body from the puncture point along the wall of the drainage tube, causing the patient's clothes and bedding to become damp, increasing the patient's discomfort and reducing the patient's quality of life. If local suturing is performed again, it will cause further harm to the patient. To address the above defects, we have proposed a suture-free and leak-proof peritoneal drainage tube. Utility Model Content

[0006] The main purpose of the utility model is to provide a suture-free and leak-proof abdominal drainage tube. A guide tube mechanism is arranged at the tube body of the drainage tube body. When the drainage tube body, carrying the suction tube part and the rubber wrapped tube, enters the abdominal drainage position, the guide tube mechanism can fill the rubber wrapped tube outside the drainage tube body with gas, so that the air bag portion expands and bulges into a spherical air bag to form a stop position in the abdominal wall drainage hole, which can prevent the drainage tube body from slipping outward, so that the drainage tube body does not have the skin pulling and pain problem caused by suture fixation, and the bulge of the air bag fully fits the tissue at the skin drainage wound, playing a role of fixation and leakage prevention; and when the tissue near the abdominal wall drainage hole becomes loose and causes the drainage tube body to shake, gas can be injected into the rubber wrapped tube again, so that the air bag portion bulges and fits the tissue near the abdominal wall drainage hole again, preventing leakage at the abdominal wall drainage hole and avoiding the problem of accidental falling off of the drainage tube body, which can effectively solve the problems in the background technology.

[0007] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0008] A suture-free and leak-proof abdominal drainage tube, comprising a drainage tube body and a drainage tube mechanism, wherein the drainage tube mechanism comprises a liquid suction tube portion, a V-shaped notch, a rubber tube, a shrink tube portion A, a shrink tube portion B, a curved connecting tube, a hard tube, a rubber seal and an air bag bag, wherein the distal end of the drainage tube body is integrally formed with the liquid suction tube portion, and the distal end of the liquid suction tube portion is symmetrically provided with a V-shaped notch, and a side suction port is provided on the surface of the liquid suction tube portion behind the V-shaped notch. The drainage tube body at the rear is clamped with a rubber tube, and the tube ends of the rubber tube are symmetrically provided with a tube reduction part A and a tube reduction part B. The tube reduction part A and the tube reduction part B are fixed on the outside of the tube body of the drainage tube body, and the outer tube wall of the rubber tube near the tube reduction part B protrudes outward with a bent connecting tube. A hard tube is inserted and fixed in the bent connecting tube, and a rubber seal is fixed in the tube end of the hard tube away from the bent connecting tube. The rubber tube protrudes symmetrically with an air bag bag on the outside of the tube body near the tube reduction part A.

[0009] Furthermore, the airbag package has four groups of protrusions symmetrically arranged outside the rubber tube;

[0010] Through the above technical solution, the rubber-wrapped tube is provided with multiple groups of airbag bags protruding from the outside, which can form multiple groups of anti-retraction structures at the wound where the drainage tube body is fixed.

[0011] Furthermore, an arc portion is provided at the outer corner end of the V-shaped notch;

[0012] With the above technical solution, after the outer corner end of the V-shaped notch is set as an arc mouth part, it is less likely to cause additional damage when the suction tube part enters the wound.

[0013] Furthermore, the pipe opening of the bent connecting pipe is inserted into the pipe body of the hard pipe by interference fit;

[0014] Through the above technical solution, the hard pipe can be firmly clamped in the bent connecting pipe for communication, so that the hard pipe is not easy to fall off at the bent connecting pipe.

[0015] Furthermore, the rubber tube is interconnected with the airbag bag and the bent connecting tube, and the thickness of the airbag bag is smaller than the thickness of the rubber tube;

[0016] Through the above technical solution, after gas is injected into the bent connecting tube from the hard tube, the gas can enter the airbag bag along the rubber bag, and the thinner bag body of the airbag bag can expand and bulge outward after the gas enters.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The utility model provides a guide tube mechanism on the tube body of the drainage tube body. When the drainage tube body, with the suction tube part and the rubber tube, enters the abdominal drainage position, the guide tube mechanism can fill the rubber tube outside the drainage tube body with gas, so that the air bag portion expands and bulges into a spherical air bag to form a stop position in the abdominal wall drainage hole, thereby preventing the drainage tube body from slipping out. The drainage tube body does not suffer from the skin pulling and pain caused by suture fixation. In addition, the bulge of the air bag fully fits the tissue of the skin drainage wound, playing a role of fixation and leakage prevention.

[0019] When the tissue near the abdominal wall drainage hole becomes loose and causes the drainage tube body to shake, gas can be injected into the rubber bag to make the air bag bulge again and fit the tissue near the abdominal wall drainage hole, preventing leakage at the abdominal wall drainage hole and avoiding the problem of accidental detachment of the drainage tube body.

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1-3 As shown, a suture-free anti-leakage abdominal drainage tube includes a drainage tube body 1 and a guide tube mechanism 2. The guide tube mechanism 2 includes a liquid suction tube portion 3, a V-shaped notch 4, a rubber tube 7, a shrink tube portion A8, a shrink tube portion B9, a curved connecting tube 10, a hard tube 11, a rubber seal 12 and an air bag bag 13. The distal end of the drainage tube body 1 is integrally formed with the liquid suction tube portion 3, and the distal end of the liquid suction tube portion 3 is symmetrically opened with a V-shaped notch 4. A side suction port 6 is opened on the surface of the liquid suction tube portion 3 behind the V-shaped notch 4. The liquid suction tube portion 3 is provided with a lateral suction port 6. The drainage tube body 1 at the rear is externally clamped with a rubber wrapping tube 7, and the two end tube openings of the rubber wrapping tube 7 are symmetrically provided with a shrinkage tube part A8 and a shrinkage tube part B9. The shrinkage tube part A8 and the shrinkage tube part B9 are fixed on the outside of the tube body of the drainage tube body 1, and the outer tube wall of the rubber wrapping tube 7 near the shrinkage tube part B9 protrudes outward with a bent connecting tube 10, and a hard tube 11 is inserted and fixed in the bent connecting tube 10, and a rubber seal 12 is fixed in the tube opening of the hard tube 11 away from the bent connecting tube 10, and the rubber wrapping tube 7 is symmetrically protruded with an airbag bag 13 on the outside of the tube body near the shrinkage tube part A8.

[0026] The airbag package 13 has four groups of protrusions symmetrically arranged outside the rubber package tube 7;

[0027] Through the above technical solution, the rubber tube 7 is protruded with multiple groups of air bag bags 13, which can form multiple groups of anti-retraction structures at the wound where the drainage tube body 1 is fixed.

[0028] Wherein, an arc portion 5 is provided at the outer corner end of the V-shaped notch 4;

[0029] With the above technical solution, after the outer corner end of the V-shaped notch 4 is set as the arc opening 5, it is less likely to cause additional damage when the suction tube part 3 enters the wound.

[0030] The pipe opening of the bent connecting pipe 10 and the pipe body of the hard pipe 11 are interference-fitted;

[0031] Through the above technical solution, the hard tube 11 can be firmly clamped in the bent connecting tube 10 for communication, so that the hard tube 11 is not easy to fall off at the bent connecting tube 10.

[0032] The rubber tube 7 is interconnected with the airbag package 13 and the bent connecting tube 10, and the thickness of the airbag package 13 is less than the thickness of the rubber tube 7;

[0033] Through the above technical solution, after gas is injected into the bent connecting tube 10 from the hard tube 11, the gas can enter the airbag package 13 along the rubber package 7, and the thinner package of the airbag package 13 can expand and bulge outward after the gas enters.

[0034] It should be noted that the utility model is a suture-free and leak-proof abdominal drainage tube, in which a guide tube mechanism 2 is provided at the tube body of the drainage tube body 1. When the drainage tube body 1 needs to enter the drainage position from the abdominal wall drainage hole for abdominal drainage, the drainage tube body 1 first enters the drainage position through the abdominal wall drainage hole with the suction tube portion 3, and the rubber-wrapped tube 7 connected to the shrink tube portion A8 outside the drainage tube body 1 can also enter the abdominal wall drainage hole. Liquid can enter the V-shaped notch 4 and the side suction port 6 of the suction tube portion 3. At this time, the metal needle of the syringe can be used to pass through the rubber seal 12 of the hard tube 11, and then gas is input at the bend connecting tube 10. Under the continuous delivery of gas, the rubber-wrapped tube 7 outside the drainage tube body 1 is filled with gas, so that the air bag bag 13 expands and convexly into a spherical air bag to form a stop position in the abdominal wall drainage hole, which can prevent the drainage tube body 1 from slipping outward. At this time, the metal needle of the syringe is pulled out. The needle is a needle, and the needle hole at the rubber seal 12 is deformed and closed under the action of the rubber elastic force, so that the drainage tube body 1 does not need to be fixed with sutures, and the bulge of the air bag bag 13 fully fits the skin drainage wound, which plays a role in fixing and leak prevention. If the tissue near the abdominal wall drainage hole becomes loose, gas can be injected into the rubber bag tube 7 to make the air bag bag 13 bulge again and fit the tissue near the abdominal wall drainage hole to prevent leakage at the abdominal wall drainage hole. When the drainage tube body 1 needs to be removed from the abdominal wall drainage hole, the metal needle of the syringe is used to pierce the rubber seal 12, and then the gas in the rubber bag tube 7 is extracted, so that the air bag bag 13 loses gas and shrinks, and then the drainage tube body 1 and the suction tube part 3 can be removed from the abdominal wall drainage hole. The length of the suture-free and leak-proof abdominal drainage tube of the utility model can be divided into different models according to usage requirements, and different models can be selected according to the thickness of the abdominal wall of the abdominal CT.

[0035] It should be noted that the present invention is a suture-free and leak-proof abdominal drainage tube. The components in the present invention are all components known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or conventional experimental methods.
