Problems solved by technology

The use of puncture needles for direct drainage has disadvantages such as inconvenient operation and easy damage to viscera, and it is not easy to achieve thorough drainage and flushing, and it is also inconvenient for treatment operations such as infusion and blood transfusion
Because there is no special body cavity puncture and drainage device available, it has caused a lot of inconvenience and medical accidents in clinical practice

Embodiment Construction

[0013] Such as figure 1 As shown, the main body of the puncture drainage device is an elongated flexible tube 3, and the inner diameter of the flexible tube is 3mm. The left end of slender hose 3 is tapered body 1, and tapered body 1 is molded into arc shape, and its front end opening has 6-12 side holes 2 on the back root pipe body. A multi-way valve 4 is provided on the right end body of the elongated flexible hose 3 . The multi-way valve 4 can adopt the accessory three-way valve structure in the existing clinically used catheter apparatus group, that is, a cock is arranged on the central hole of the valve body, and the rotation of the cock can communicate with or close any two holes on the valve body, or it can be completely closed. Through or fully closed three holes on the valve body. figure 1 Among them, the valve body of the multi-way valve 4 is connected with the main port 5 in the same direction as the hose 3 and the bypass port 6 perpendicular to the hose. Both po...

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 ...
