Description

neurosurgery drainage device

technical field

The utility model belongs to the field of medical instruments, in particular to a drainage device for neurosurgical operations.

Background technique

The brain is the most complex part of the human body, and the information about the brain nerves is relatively difficult and risky. Due to the rich blood vessels in the brain, multi-level separation is required, and there will be more bleeding, which requires postoperative surgery. Drainage of exuded blood and other waste liquid, in the prior art, it is mainly to place a common drainage hose on each layer. The output end of this method does not dredge the hose, and the end of the drainage hose is often bent to cause blockage. It increases the probability of wound infection, and it is also easy to cause the drainage to leak out, which increases the probability of infection. Second, the drainage hose often uses a flexible hose. A certain fluctuation is not conducive to drainage, and at the same time, too fast drainage will also affect the fluctuation of the brain, which is not conducive to the operation.

In addition, the dynamic change of intracranial pressure is an important index to understand the condition changes of patients with external ventricular drainage. Continuous and accurate monitoring of intracranial pressure can provide a reliable basis for clinical diagnosis and treatment. Therefore, it is necessary to use another tube to detect the intracranial pressure during drainage, which not only complicates the operation procedures of medical staff, but also increases the pain of the patient and the cost of the operation, and infection is more likely to occur in multiple openings.
