Abstract
Description
Technical Field
[0001] The invention relates to the technical field of ventricular drainage, and in particular to a ventricular drainage monitoring and control device. Background Art
[0002] Ventricular drainage is a procedure in which a hole is drilled through the skull to puncture the lateral ventricle and a drainage tube is placed to drain cerebrospinal fluid, bloody cerebrospinal fluid, or infected cerebrospinal fluid to the outside of the body. The purpose is to reduce blood stimulation to the meninges, lower intracranial pressure, remove intraventricular blood, reduce wound cerebrospinal fluid leakage, or flush through the ventricles with drugs to promote infection control.
[0003] In clinical practice, similar incidents often occur, which may endanger life or cause a series of adverse consequences: 1. The drainage pot accidentally leaves its original height for various reasons, causing the pressure inside the pot to be lower than the ventricular pressure, resulting in a large outflow of cerebrospinal fluid in a short period of time; 2. The patient suddenly becomes restless, suffers from epileptic convulsions, etc., causing the intracranial pressure to rise suddenly, which is higher than the outlet pressure at the top of the drainage pot, and the cerebrospinal fluid will flow out unplanned; 3. The patient's head is suddenly raised, and the original position of the drainage pot remains unchanged, which cannot maintain the original intracranial pressure and causes the cerebrospinal fluid to flow out unexpectedly. However, existing medical equipment often cannot provide timely warnings. When medical staff discover it, a large amount of cerebrospinal fluid may have been lost, making it difficult to maintain normal intracranial pressure. Therefore, we propose a ventricular drainage monitoring and control device. Summary of the invention
