Description

A multifunctional medical negative pressure drainage device

technical field

The invention relates to the technical field of drainage devices, in particular to a multifunctional medical negative pressure drainage device.

Background technique

Negative pressure drainage is a necessary treatment for various operations. For large-scale operations or operations with a large amount of blood, the capacity of a single negative pressure suction bottle cannot meet the surgical requirements. When the blood in the negative pressure suction bottle is full, the operation must be suspended. The replacement of the negative pressure suction bottle hinders the smooth progress of the operation, and even causes harm to the patient. In addition, the commonly used negative pressure suction device is only connected to one suction head to complete the cleaning of one substance. For some operations, especially There is a lot of smoke in laparoscopic surgery, and two-way suction must be used to clean up the blood and smoke at the same time. Finally, after the drainage bottle is used, other parts need to be disassembled, the liquid is poured out from the inside of the drainage bottle, and the other parts are assembled after cleaning. The operation is troublesome, time-consuming and labor-intensive.

In the prior art, a medical negative pressure suction and drainage device with the application number "201621272713.4" includes a negative pressure collection bottle, a negative pressure drainage tube and a syringe. The one-way suction valve and the one-way exhaust valve are respectively connected to the road interface, and the one-way suction valve is connected with the negative pressure collection bottle through the catheter, and the sealing bottle stopper II is arranged on the negative pressure collection bottle, and the sealing bottle stopper II is provided with Negative pressure drainage tube. A buffer bottle is added between the negative pressure collection bottle and the syringe, and the buffer bottle is provided with a sealed bottle stopper I. The buffer bottle is connected with the syringe through a catheter on the one hand, and connected with the negative pressure collection bottle through a connecting tube on the other hand. The negative pressure suction and drainage device has a simple structure and is easy to operate, and can always keep the negative pressure within a reasonable range of drainage negative pressure, so as to achieve continuous and stable drainage, sufficient drainage and good effect.

However, there are still relatively obvious defects in its use: 1. The capacity of the drainage bottle is limited. If the drainage material exceeds a certain amount, the negative pressure in the bottle will be low, and the drainage effect will not be achieved, and the drainage cannot be performed without interruption. 2. The drainage pipeline is relatively single, which cannot meet the needs of drainage of blood, smoke, etc. during the operation; 3. The cleaning process is relatively troublesome. It needs to be disassembled and assembled part by part, which is time-consuming and laborious.
