Description

Technical Field

[0001] The utility model relates to the field of medical instruments, in particular to a multifunctional negative pressure ball. Background Art

[0002] Breast cancer surgery is a common treatment method. In order to eliminate bleeding and exudate in the skin flap after the operation, a negative pressure drainage device is usually used. Negative pressure drainage uses the principle of negative pressure to compress the skin flap so that it fits against the chest wall, promotes wound healing, and reduces the occurrence of complications. Drainage tubes are generally made of elastic latex tubes, which are placed under the armpit and under the clavicle respectively. Double-tube negative pressure drainage is used to achieve the best effect. Negative pressure drainage can not only effectively discharge excess fluid in the body, but also reduce the risk of infection and promote wound healing.

[0003] During the operation, the drainage tube needs to be sneaked through the subcutaneous tissue to the wound surface to avoid air leakage around the tube. However, there are some technical difficulties in the actual operation. For example, in the process of re-squeezing the negative pressure ball to form negative pressure after pouring out the drainage fluid, air may flow back into the wound surface. This situation will not only affect the drainage effect, but may also cause infection and affect wound healing. Utility Model Content
