Multipurpose puncture drainage device

Abstract

The invention concerns a multi purpose puncture drainage device for transferal of human body medium. The main body of the puncture drainage device is a slim soft tube, on one end of which, a cone-shaped body is provided, the front end of the cone opens, and a plurality of side holes are provided on the rear end of cone tube, while on the other end of the slim soft tube, a multiport valve is installed, connecting with a main port and a side port on its valve body. The invention can be used as special puncture drainage device for draining body cavity dropsy, hematocele and pneumatosis . It can also be applied for transfusion for central vein liquid transfusion, blood transfusion, pressure measurement and treatment.

Description

technical field

[0001] The invention relates to a drainage device for transferring human body media, in particular to a multipurpose puncture drainage device. Background technique

[0002] At present, there is no special puncture and drainage device for drainage of effusion, blood and gas in the clinical medicine, so only other related devices can be used to replace it clinically, and the puncture and drainage can only be implemented. Commonly used alternatives include central venous catheters, pigtail catheters, and puncture needles. A "central venous catheter" is a long, thin, flexible tube with only an end hole at the front end. Because it is used as a catheter for penetrating into veins, there is no side hole on the tube body at the end, and the lumen is small, with a maximum inner diameter below 2.4mm. Central venous catheters are used as puncture and drainage devices. Since there are only end holes and the diameter of the tube is small, when draining pus-filled body ...
