TECHNICAL FIELD

[0001] The utility model relates to airtightness detection technical field especially relates to a negative pressure dressing airtightness detection device. BACKGROUND

[0002] Skin and soft tissue injury is the main injury class of trauma. But due to the factors such as not timely treatment, complex injury, or nursing negligence, skin wound infection, blood supply disorder, etc. are easy to appear, leading to wound delay healing. At the same time, with the population aging in China, the incidence of skin ulcers caused by various chronic diseases such as diabetes, vascular diseases, pressure sores, etc. increases year by year. Due to poor blood circulation of the wound of the patient, proliferation and migration disorder of skin repair cells at the wound edge, etc. chronic wounds are often formed, which makes the wound difficult to heal, and seriously affects the appearance and functional rehabilitation of the patient. At present, the domestic treatment of this kind of wound mostly adopts negative pressure drainage technology. Negative pressure drainage technology can avoid wound infection through continuous drainage, effectively promote endothelial cell proliferation, angiogenesis and meat tissue formation in the wound, and play an important role in maintaining a good wound microenvironment and promoting wound healing.

[0003] The working principle of negative pressure dressing is to provide a closed wound treatment space for the patient by continuously drawing negative pressure. Therefore, the airtightness detection of negative pressure dressing is very important. The airtightness of negative pressure dressing mainly detects the following three points: 1. whether the adhesion of the suction cup and the dressing is sealed; 2. whether the adhesion of the suction cup and the catheter is sealed; 3. whether the dressing back film is damaged.

[0004] Usually, the airtightness of negative pressure dressing is judged by using reductio ad absurdum. First, it is assumed that the airtightness of the dressing to be tested is qualified, the release film of the dressing is torn off for application, an edge strip is attached around the dressing, and then negative pressure is drawn for detection. As long as the negative pressure value can reach the target range, it can prove that the airtightness is qualified, otherwise the dressing leakage can be found. However, this detection method needs to tear off the release film at the bottom of the dressing, resulting in the loss of the dressing. In addition, the preparation work before detection is complicated, time-consuming and labor-intensive. UTILITY MODEL CONTENTS
