Abstract

The intelligent cerebrospinal fluid replacing instrument consists of two parts, including a disposable replacing cylinder and a driving and controlling device capable of being reused. Inside the replacing cylinder with replacing port for the drainage pipe to be connected on and sucker, artificial cerebrospinal fluid is held. The driving and controlling device includes mainly a mechanical driving unit and an automatic control unit. The present invention has a program driven pushing and sucking pump with constant speed and constant displacement, and parameters capable of being set based on disease condition, so that it has intelligently controlled speed, time and pushing and sucking amount of the replaced cerebrospinal fluid and is scientific, accurate, safe and efficient.

Description

technical field

[0001] The invention relates to a medical device, especially an intelligent cerebrospinal fluid replacement instrument, which is mainly used to purify the cerebrospinal fluid contaminated by bloody, inflammatory or abnormal immune substances in the subarachnoid space of the spinal cord caused by various diseases. Background technique

[0002] It has been proved that the removal of blood, inflammatory or abnormal immune substances in the human cerebrospinal fluid, that is, the cerebrospinal fluid replacement technology, is the treatment and prevention of major diseases that seriously threaten human health - hemorrhagic cerebrovascular diseases (such as subarachnoid hemorrhage, ventricular hemorrhage, etc.) ), central nervous system infections (such as tuberculosis, suppurative, fungal and viral meningitis, etc.), demyelinating neuropathy and its complications, and people have recognized the clinical value of this technique. The current main operation method of...
