Negative pressure drainage tube fixing device with gauze replacement function

Abstract

The invention relates to the technical field of medical instruments, in particular to a negative pressure drainage tube fixing device with a gauze replacement function. The device comprises an annulardressing paste, a plastic ring, a negative pressure suction internal capsule, a gauze accommodating box and a tapered cap with an internal thread; the plastic ring is provided with clamping grooves,holes are formed in the surface of the gauze accommodating box, the upper end of the gauze accommodating box is provided with a drainage tube fixing tube, the drainage tube fixing tube is divided intotwo parts, the head end of the drainage tube fixing tube is a conical umbrella-shaped side wing, and the outer ring of the head end of the drainage tube fixing tube is provided with a thread. The device can be widely popularized in the aspects of drainage tube fixation and infection prevention in the fields of various surgeries and the like.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a negative pressure drainage tube fixing device capable of replacing gauze. Background technique [0002] After surgery, in order to drain bile, exudate, pleural effusion, etc. in the abdominal cavity, thoracic cavity, and subcutaneous body, it is often necessary to place a drainage tube. In order to prevent the displacement of the drainage tube, the drainage tube needs to be fixed. Gauze needs to be placed around the drain and changed periodically. If there is a lot of exudate from the outer port of the drainage tube, the gauze needs to be replaced repeatedly in order to avoid retrograde infection. [0003] At present, the common methods of fixing the drainage tube after surgery include suturing, that is, suturing the drainage tube to the surrounding abdominal wall, or using a drainage tube fixer or stickers to fix the drainage tube, and then cutting the "Y" inner mouth...

AI Technical Summary

Problems solved by technology

The above method of fixing and placing gauze has the following deficiencies: 1. The drainage tube is easy to pull down the suture and cause tissue traction with the movement of breathing and body muscles, resulting in specific pain; 2. The continuous traction of the fixed suture can cause abdominal wall Cutting and sutures falling off, and then losing the fixing effect of the drainage tube; 3. The contact area between the film of the common drainage tube holder and the abdominal wall is small, and the drainage tube holder is a disposable consumable, and the seepage around the drainage tube is polluted and fixed After the film is attached to the drainage tube, the fixing effect of the drainage tube is lost, so it can only be removed or replaced; 4. Although the drainage tube fixing sticker has a large contact area with the abdominal wall, it is easily polluted by the exudate around the drainage tube, resulting in the adhesion of the fixing sticker to the abdominal wall. 5. It is difficult to clean the bottom of the fixed patch, which is easy to breed bacteria and cause retrograde infection; 6. Use iodophor and alcohol to thoroughly disinfect the bottom of the drainage tube fixed patch, which will easily cause the fixed patch to lose its adhesion to the abdominal wall , resulting in the falling off of the fixing sticker and the displacement of the drainage tube; 7. When the drainage tube fixing sticker fixes the ordinary drainage tube, it is easy to fold the fixed part of the drainage tube, resulting in poor fluid drainage in the body; 8. After placing gauze around the drainage tube, still It is necessary to use adhesive tape to fix the gauze, and long-term activities will easily lead to the decrease of adhesive force of the adhesive tape and the displacement of the gauze; Workload and treatment costs; 10. When changing the gauze, the adhesive tape on the surface of the gauze needs to be removed, the skin and hair are pulled and it is easy to cause pain, and the amount of adhesive tape is increased at the same time
