[0002] There are many areas ≤10cm when changing dressings in outpatient clinics 2 , 3-5cm long wounds, or 2-3cm deep sinus tracts, small secretions (less than 5ml), fresh wounds, no special infections, good disease control, but slow wound growth. These patients are unwilling to undergo re-surgery, standard negative pressure surgery increases the financial burden on patients, and requires hospitalization. Simple negative pressure surgery in outpatient clinics is inconvenient to carry and difficult to close the wound.

[0003] The treatment method for the above wound generally adopts the following steps: 1. Routinely clean and disinfect the wound; 2. Use a scalp needle to trim the side hole at the end of the needle, place the trimmed end into the wound, and cover the surface with sterilized wet gauze; 3. Cover the surface with a translucent dressing, connect the needle tube (20ml), and draw back the needle tube to form negative pressure to promote wound healing. It usually heals in 1-2 times.

[0004] However, the above treatment method has the following problems: 1. The scalp needle is too thin and inconvenient to trim; 2. The needle tube is easy to fall off during the process of withdrawing the negative pressure; 3. The needle tube is difficult to fix and needs multiple fixations with tape, but it is still not firm.

[0005] Therefore, there is an urgent need for an improved needle tube for mini negative pressure therapy that can solve the above problems. Utility Model Content
