In clinical medicine, cerebrospinal fluid external drainage is a safe and effective minimally invasive method for treating neurosurgical diseases such as cerebrospinal fluid leakage, intracranial infection, subarachnoid hemorrhage and the like; has better curative effect on postoperative severe craniocerebral injury, traumatic subarachnoid hemorrhage, various intractable cerebrospinal fluid otorrhea, rhinorrhea and incisional fistula, and the treatment of intracranial infection, intractable subcutaneous hydrops and traffic hydrocephalus.
The external drainage of cerebrospinal fluid means that the drainage tube is placed into the ventricle to continuously drain out the cerebrospinal fluid, so that the drainage tube can reduce the intracranial pressure and promote the discharge of inflammatory cerebrospinal fluid to clean the cerebrospinal fluid and assist in treating the inflammation of the ventricle. The drainage quantity of cerebrospinal fluid leakage must be strictly controlled, so that the condition of low intracranial pressure is further aggravated due to overlarge drainage quantity, and severe complications such as epidural hemorrhage, cerebral hernia and the like even appear to endanger the life of a patient.
In the drainage operation process, how to accurately and safely control the drainage speed and the drainage quantity of cerebrospinal fluid is a difficult problem. The traditional method is to adjust the drainage quantity by manually adjusting the relative height of the drainage tube, but the relative height is difficult to accurately control, and the over-quick drainage or over-drainage is easily caused. The drainage speed of cerebrospinal fluid is too fast, the intracranial pressure can drop rapidly, can lead to serious complications such as encephalopathy, etc.; excessive drainage of cerebrospinal fluid can lead to complications such as low intracranial pressure headache. Meanwhile, in the drainage process, because the patient is generally in a state of unconsciousness, the patient can not be controlled to turn over and other activities, the stretching of the drainage pipeline is particularly easy to cause the position change of the drainage pipeline in the encephaly of the patient, so that the drainage effect is influenced, and the nursing difficulty of the patient is increased. In the existing cerebrospinal fluid drainage process, in order to balance intracranial pressure, medical workers need to continuously adjust the height of a drainage kettle so as to keep the drainage speed and height of cerebrospinal fluid or hematoma, and the operation complexity of the medical workers and the requirement on the number of the medical workers are improved.
