Abstract
Provided is a drainage tube fixing device. The drainage tube fixing tube comprises a U-shaped clip, a high-friction fixing block, a water absorbing pad and a fixing adhesive plaster. A left fixing block and a right fixing block are respectively inlaid in arc-shaped locating blocks which are respectively arranged in the middle of a left arm and a right arm of the U-shaped clip, wherein the left fixing block and the right fixing block are matched with each other, are made of high-friction medical flexible materials and can carry out stretching out and closing up movements along with the left arm and the right arm of the U-shaped clip. When the left arm and the right arm of the U-shaped clip are stretched out, a drainage tube can be conveniently placed into. When the left arm and the right arm of the U-shaped clip are slightly pressed, and the U-shaped clip is in a closed up and locking state, the high-friction fixing block which is composed of the left fixing block and the right fixing block after the left fixing block and the right fixing block are closed up is capable of encircling the drainage tube and fixing the drainage tube. A guide face on the high-friction fixing block provides good support at an outlet of the drainage tube, can avoid that the drainage tube is bent, and is good in drainage effect. The water absorbing pad can absorb tissue fluid which oozes out of a placing cut of the drainage tube. The fixing adhesive plaster is attached to skin, and firmly fixes the U-shaped clip, the water absorbing pad and the drainage tube. The drainage tube fixing device is easy to assemble and disassemble, and even a drainage tube made of ultra-slithery materials can be firmly fixed, and can be smooth in drainage.
Description
Technical field
This utility model relates to a kind of surgical operating instrument, particularly surgical operation fixer of drainage tube tool.
Background technology
The surgical drainage tube kind of using clinically is a lot, is respectively applied to chest drainage, encephalocoele drain, gastrointestinal tract drain, biliary drainage, urethral catheterization etc.The purpose of surgical drainage on the one hand is the various hydrops between tissue or in the body cavity to be directed to external, prevents postoperative infection, accelerating wound; Be to be convenient to have or not in the clinical follow field of operation active hemorrhage or anastomosis to spill on the other hand, check, detect the variation of character, quantity and the composition of various drainage-fluids, for clinical treatment provides foundation.To fixing of drainage tube, fixed form commonly used is to adopt silk suture to fix clinically.But the method that silk suture is fixing increases the wound of tissue easily, increases the tissue infection chance, and the stitching thread traction is organized and also caused easily patient's pain.Suturally involve for a long time, cause easily the tissue cutting, increase the weight of tissue injury; And after tissue cut off, suture came off, and needed again to sew up, with fixing drainage tube.In addition, the method that silk suture is fixing, the easy slippage of drainage tube, displacement.
For sewing up clinically the fixed form shortcoming, adopt at present the fixed forms of adhesive types more.In Chinese patent ZL200520058185.8, disclose a kind of drainage tube fixing plaster, adopted canned paragraph and be attached thereto many structures of twining bar that connect, canned paragraph is fixed on the skin, be wrapped on the drainage tube and twine bar, thereby reach the fixedly purpose of drainage tube.In patent application 200710008574.3, a kind of drainage tube fixing plaster is disclosed, its principle is with Chinese patent ZL200520058185.8, the mode that only is winding bar source is different, the suture that cracking is arranged by punching on substrate sheets, form the take-up strap that the middle part starts, fix drainage tube.In patent application 200710009458.3, a kind of fixer of drainage tube is disclosed, by the other drainage tube bandage that is being provided with of the drainage tube port on substrate sheets, with the drainage tube bandage bundle, fixing drainage tube.Its advantage of fixed form that above-mentioned 3 patents have represented adhesive type is to sew up, the wound of tissue and the probability of infection have been reduced, but drainage tube lacks support in the drainage tube exit, easily bending, in addition, at present senior drainage tube adopts the superslide material manufacture, and very difficult stickup is fixing and binding is fixing.
In US Patent No. 2008/0243082A1, a kind of drainage tube fixing device is disclosed, set up arcuate channels to solve the drainage tube exit and lacked support, the problem of easy bending, but the mode that drainage tube still adopts stitching thread to tie up is fixed on the arcuate channels, does not overcome the difficult problem that the drainage tube of superslide material manufacture is difficult to tie up.
In Chinese patent ZL201020201511.7, a kind of drainage tube fixing device is disclosed, oppress clamp sleeve by the rotation of nut, utilize the contraction of clamp sleeve, fix drainage tube.This product exists the drainage tube exit lack to support, and easily bending affects the shortcoming of drain; Complicated operation when drainage tube installs and fixes, the centripetal contract by distance of the clamp sleeve that plastics are made is limited, and difficult drainage tube to the superslide material manufacture forms effectively fixing, and drainage tube is shifted easily.In Chinese patent ZL201120041947.9, a kind of drainage tube fixing device is disclosed, by the clamp mechanism of setting up the fixed cover groove cover that is fixedly clamped, form fixing to drainage tube.This product exists the drainage tube exit lack to support equally, and easily bending affects the shortcoming of drain; In addition, complicated operation when drainage tube installs and fixes, clamp mechanism is difficult for freeing.
In sum, in the drainage tube fixing device of prior art, exist the drainage tube exit lack to support, easily bending affect the shortcoming of drainage effect, and drainage tube shortcoming such as complicated operation when installing and fixing, and needs further improvement.
