Subcutaneous inflatable drainage support frame

Abstract

The invention relates to a medical instrument, in particular to an auxiliary subcutaneous drainage supporting device used for processing various refractory chronic wounds and various infected incisions, keeping dryness of wound surfaces and promoting union of wounds after various acute trauma surgical operations. The auxiliary subcutaneous drainage supporting device comprises a drainage tube, a ventilation tube is arranged in the drainage tube, an air bag communicated with the ventilation tube is arranged at the top end of the drainage tube, and a drainage hole is further formed in the end, where the air bag is arranged, of the drainage tube. The auxiliary subcutaneous drainage supporting device further comprises an air flow control device used for inflating the ventilation tube. The auxiliary subcutaneous drainage supporting device is small in size, low in weight, convenient to carry, simple and feasible in operation, strong in pertinence and wide in practicability; defects of open wounds are overcome; a closed in-vivo growth environment is created for newly-born granulation tissue; the probability of secondary infection of the whole wound is lowered; body fluid circulation is promoted; forming and growing of granulation tissue is stimulated, and unhealthy granulation tissue can be avoided; bacterium content is lowered, and wound union is promoted.

Description

technical field [0001] The invention relates to a medical device, in particular to an auxiliary subcutaneous drainage support frame for keeping the wound dry and promoting wound healing after various acute trauma surgeries, various refractory chronic wounds and various infected incisions. Background technique [0002] In acute trauma surgery, various refractory chronic wounds and abdominal surgery, incision infection is still a common postoperative complication. On the one hand, incision infection increases the pain of patients and prolongs the length of hospital stay; on the other hand, it increases medical expenses and burdens patients; it even leads to medical disputes and medical malpractice. [0003] At present, the method of opening the incision to drain and suture more is adopted for the incision of postoperative infection. That is, in the case of an open incision, a subcutaneous drainage strip is placed to drain the purulent secretion or sewage from the infected inc...

AI Technical Summary

Problems solved by technology

Although this method has a certain effect of preventing wound infection, it is cumbersome and increases the suffering of patients and the workload of medical staff.

At the same time, this method obviously has its own limitations: (1) Epithelial cells in skin tissue proliferate rapidly, and their repair speed is significantly faster than the formation of new granulation tissue. The skin tissue is easy to bend inward, which makes it difficult to suture the incision, and leaves a large scar after suturing; (2) During the process of opening the wound, the new granulation tissue is directly exposed to the air, which is easy to cause re-infection; (3) In the open wound , the growth rate of new granulation tissue is obviously delayed due to the reduction of local blood supply

(4) When placing drainage strips for drainage, if the dressing replacement time is not properly controlled, some granulation tissue will easily grow into the grid gap of the dressing, and will stimulate the production of unhealthy granulation tissue, which will significantly increase the patient's pain and hospitalization time
