Description

Technical Field

[0001] The utility model relates to the technical field of application, in particular to a pressurized application. Background Art

[0002] In medical treatment, after the puncture or incision is treated, it is often necessary to apply pressure to the corresponding part. For example, cancer patients mainly use deep venous catheters, such as CVC, PICC, PORT (infusion port), etc. for intravenous infusion of chemotherapy drugs. As cancer patients' requirements for comfort in daily life continue to increase, cancer patients choose PORT (infusion port) as a deep venous catheter for drug treatment. On the day of implantation of PORT (infusion port), the incision needs to be pressurized to stop bleeding. Gauze and tape are conventionally used for pressurized hemostasis. The tape is easy to loosen, and the effect of pressurized hemostasis is generally poor. It is easy for the wound to ooze blood, and it needs to be replaced again for pressurized hemostasis.

[0003] At present, there are also dressings that use airbags for pressurization. For example, publication number CN208319415U discloses a pressurized and leak-proof aseptic improved dressing, which is provided with an adhesive dressing surface layer; the adhesive dressing surface layer is attached with a built-in thin rectangular rubber small airbag; the lower layer of the built-in thin rectangular rubber small airbag is attached with a sterile square cotton layer; the lower layer of the sterile square cotton layer is attached with a waterproof film. The small airbag is inflated by inflation to play a role in compression and hemostasis; it can also reduce the formation of dead space in the wound, which is conducive to wound healing. The disadvantage is that it is impossible to know the compression bleeding situation.

[0004] Publication No. CN215307399U discloses a new type of transparent minimally invasive surgical dressing capable of pressurized hemostasis. In this patent, the bleeding of the patient's wound can be observed by making the dressing transparent. However, it is not convenient to evaluate and judge the depth of bleeding on the dressing.
