Description

Technical Field

[0001] The utility model belongs to the technical field of medical instruments, and in particular relates to a cavity puncture drainage device. Background Art

[0002] In the prior art, when performing chest and abdominal puncture and drainage, the puncture needle directly absorbs the accumulated fluid after puncture. If the accumulated fluid is large, it is necessary to separate the syringe from the original needle and replace the syringe to continue to absorb, or use the existing puncture needle to place a drainage tube for long-term drainage. During the absorption and drainage process, the needle is easy to shake on the patient's body surface. At the same time, during the operation, the needle hole will be in contact with the air for a long time, which has the risk of infection. Chinese patent document CN 219516463 U discloses a chest puncture device, which is fixed by a fixing belt. The fixing position is relatively high, and there are still problems such as the instability of the needle and the long-term exposure of the insertion position. Utility Model Content
