Intelligent anti-backflow and anti-infection incision drainage system

Abstract

The invention belongs to the technical field of neurosurgical drainage, and discloses an intelligent anti-backflow and anti-infection incision drainage system. The system is provided with an incisiondrainage device; a one-way valve is embedded in the incision drainage device, and a drainage tube is clamped with the one-way valve; the one-way valve is connected with a double U-shaped connecting pipe, and the bottom of the incision drainage device is provided with a liquid discharging hole switched on and off by the one-way valve. The intelligent anti-backflow and anti-infection incision drainage system has the advantages that the purpose of the one-way valve is that liquid can only flow into the drainage tube in a negative pressure ball and cannot flow back out of the negative pressure ball; one end of the drainage tube can be connected into the one-way valve, which is more convenient and germfree in the clinic, thereby eliminating the trouble that manual crossed connection and film sealing are needed in a clinical operation, and the other end of the drainage tube is placed under an operative incision or the endocranium surface; the second-layer design that the double U-shaped connecting pipe prevents the liquid from flowing back makes the liquid difficulty enter the one-way valve no matter how a drainage ball is placed, and therefore the double protection makes it almost impossible for the liquid to flow back into the incision or the brain to cause cerebral hernia.

Description

technical field [0001] The invention belongs to the technical field of neurosurgery drainage, in particular to an intelligent anti-backflow and anti-infection incision drainage system. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] In the past, the traditional drainage device after neurosurgery often did not have a professional drainage device dedicated to neurosurgery, but used a subcutaneous drainage device commonly used in general surgery or thoracic surgery. After investigating most hospitals, it was found that the drainage device commonly used in neurosurgery is a drainage tube plus a drainage tube. Negative pressure drainage device, the device can not prevent the backflow of liquid, the airtightness is poor, it is very easy to cause intracranial infection or the possibility of brain herniation due to backflow of liquid. On the one hand, the device has an anti-backflow design, and the drainage ...

AI Technical Summary

Problems solved by technology

[0004] To sum up, the problem existing in the existing technology is that the drainage device after traditional neurosurgery can flow back, so that the drained bloody fluid flows into the subcutaneous or even intracranial again, leading to infection or even brain herniation, which is life-threatening in severe cases.
