Ventricular drainage tube surgery is a new method of drainage after brain surgery. Its main key lies in the technical implementation of the drainage catheter with scalp needle.
Drainage after craniotomy in brain department (neurosurgery) has not had unified standards and equipment. The usual method is to bury a urinary catheter or an ordinary silicone tube instead. The drainage effect is not ideal and it is easy to It is also difficult to fix the tube body if it is clogged, which brings trouble to clinical work. (Sometimes the drainage through the above method is not smooth, resulting in hematoma or blood clots, which have to be solved by a second craniotomy.)
This utility model is a medical device for external ventricular drainage. A hanging belt with holes and The fixed plate with buttons is used to adjust the height of the pressure regulator. The upper part of the pressure regulator is connected with the discharge port of the drainage pipe, and the lower part is equipped with a ventilation pipe for exhausting air. If the liquid storage bag is too full, it can be exhausted through The tube overflows, which can prevent the drainage fluid from flowing back into the brain. The bottom of the fluid storage bag is tapered, and the tip is equipped with a discharge... 1. Properly fix the drainage tube and drainage bottle (bag) on ??the bed. head, so that the drainage tube is 10~15cm higher than the level of the lateral ventricle to maintain normal intracranial pressure.
2. Control the drainage speed and volume
The drainage volume should not exceed 500ml per day to avoid the harm caused by the sudden drop in intracranial pressure.
3. Keep the drainage smooth
Avoid pressure and folding of the drainage tube. If the drainage tube is blocked, squeeze the drainage tube to squeeze out blood clots and other obstructions, or in strict Use a syringe to aspirate under sterile operation, and do not flush with saline to prevent obstructions in the tube from being flushed into the ventricular system, causing obstruction of cerebrospinal fluid circulation.
4. Pay attention to the amount and nature of drainage
If a large amount of bloody cerebrospinal fluid is drained, it indicates intraventricular hemorrhage, and turbid cerebrospinal fluid indicates infection.
5. Strict aseptic operation
To prevent retrograde infection, clamp the drainage tube when changing the drainage bag every day to prevent air from entering and cerebrospinal fluid from flowing back into the skull.
