Description

Drainage tube fixing device

Technical field

The present invention relates to a medical device, and more particularly to a drainage tube fixing device for use in a surgical procedure. Background technique

There are many types of surgical drainage tubes used clinically, some for catheterization, and some for drainage of the wound, chest, brain cavity, gastrointestinal tract, biliary tract, etc. The purpose of surgical drainage is to guide the accumulation of pus, blood and liquid in the body tissue or body cavity to the outside of the body to prevent postoperative infection and affect wound healing. On the other hand, it is convenient for postoperative observation of active bleeding in the operation area. Or the seam (kiss) joint leaks, check to monitor the changes in the traits, quantity and composition of the various drainage fluids. A commonly used drainage tube is a tube made of medical plastic or rubber. In order to ensure the smoothness of the drainage tube, the drainage tube needs to be fixed after the operation. A commonly used fixation method is suture fixation with silk thread, but the suturing operation tends to increase tissue trauma, increase the chance of tissue infection, and suture traction tissue is also prone to pain. In addition, long-term sutures tend to cause tissue cutting, aggravate tissue trauma, and the sutures fall off after the tissue is cut, and need to be sutured again to fix the drainage tube. Furthermore, there are many appliances required for suturing and fixing, and the operation is inconvenient.

In view of the fact that there are many drawbacks to the above-mentioned suture stitching method, at present, the sticking type fixing method is often used. For example, Chinese Patent Publication No. CN1011 30124A discloses a drainage tube holder which directly binds a drainage tube through a drainage tube strap on a pasted base sheet to achieve fixation of the drainage tube. Although this method does not need to sew the drainage tube to the patient's skin, but the binding tube is tied by the binding, if the system is loose, the patient is moved or turned over when the patient is manually moved or slid, and the drainage tube is easy to fall off. It is the drainage tube that must be reinserted into the patient, which increases the chance of infection of the patient. In severe cases, it may even endanger the patient's life. If it is fastened, it will affect drainage.

The Chinese Utility Model Patent Publication No. CN 2796719Y discloses a drainage tube fixing sticker comprising a substrate with an adhesive layer and a protective film covering the adhesive layer, characterized by comprising a fixed segment and connected thereto A plurality of winding strips are used to fix the drainage tube by winding the winding strips. In use, the protective film is torn off and the wrap is wrapped around and stuck to the drainage tube. Chinese Patent Publication No. CN 101011 305A discloses a drainage tube fixing adhesive tape which, in use, tears the protective film on the bottom side edge along the suture first, and ensures that the middle part picks up the adhesive tape. The protective film is not torn, and then the substrate sheet with the protective film peeled off is attached to the damaged skin tissue. After the position of the drainage tube is determined, the protective film adhered to the adhesive tape in the middle is removed, and the adhesive is laterally contained. The drainage tube is attached with a package to fix the drainage tube. Both of the above-mentioned drainage tubes are used to stick the drainage tube. If the wound condition is to be observed or the wound is to be treated, the drainage tube fixing adhesive must be torn open, and the viscosity of the drainage tube fixed after the tearing is deteriorated, and the fixation is again fixed. The effect is not good, it can only be replaced, this must It will increase the cost of the patient. Summary of the invention
