Embodiment Construction

[0008] refer to figure 1 The thoracoabdominal puncture catheter drainage device includes a steel core 1, a sandwich sleeve 2, and the sandwich sleeve 2 has anti-wrinkle and pressure threads, the steel core 1 is set in the sandwich sleeve 2, and the end of the steel core is exposed to the sandwich sleeve At the tail end, there are several circularly arranged holes 4, generally 3-5, at the 1-2mm near the head end of the outer layer of the interlayer capsule. A rubber tube 5 communicating with the cavity is provided near the end of the sandwich bag. In the illustration, two clips 6 and 7 are clamped on the rubber hose 5 to form a negative pressure section of the rubber hose. The above-mentioned sandwich bag 2 can be made of tougher hard plastic.

Abstract

The pleuroperitoneal cavity puncturing, tube setting and draining device includes a steel core and a double-layered jacketed sleeve with crinkle and compression preventing thread. The steel core is set inside the jacketed sleeve and has its end exposed beyond the sleeve; and the jacketed sleeve has ring arranged holes in the position of 1-2 mm to its head and is provided with rubber pipe communicated with the sleeve cavity. The device of the present invention is used to complete the operation of puncturing pleuroperitoneal cavity, setting tube and draining in one operation and greatly raised work efficiency while avoiding the damage to deep tissue and minimizing the infection.

Description

technical field [0001] The invention relates to a thoracoabdominal puncture catheter drainage device, which belongs to a kind of medical equipment. Background technique [0002] Existing thoracoabdominal puncture catheter drainage device operation needs to use several instruments such as syringe, puncture needle, thin guide wire, catheter. The operation needs to be carried out step by step. After local anesthesia, the puncture needle is inserted, and the pleural and ascites are drawn back when the feeling of void is felt. The thin guide wire is inserted into the thoracic and abdominal cavity through the needle tube, and then the needle tube is withdrawn. Then, the catheter sleeve is inserted into the thoracic cavity along the thin guide wire. Or the abdominal cavity, and finally the thin guide wire is pulled out. Therefore, there are many problems such as relatively cumbersome operation, many instruments involved, time-consuming, high possibility of potential organ damage, ...
