Intelligent cerebrospinal fluid drainage control and recognition warning system

Abstract

An intelligent cerebrospinal fluid drainage control and recognition warning system mainly comprises a microcomputer system (1), a flow control device (2), an infrared drop number sensor (3), a color recognition sensor (4), a pressure sensor (5), a communication module (6), a human-computer interaction interface (7) and a radio frequency recognition device (13). The intelligent cerebrospinal fluid drainage control and recognition warning system can independently set the discharge speed, the drainage amount per unit time, the drainage time interval and the drainage pressure of cerebrospinal fluid according to individual differences of patients or clinical needs so as to achieve fixed-speed discharge, quantitative discharge, timed discharge and personalized-pressure discharge of the cerebrospinal fluid; meanwhile, in the drainage process, the color recognition sensor (4) can make timely prewarning when the cerebrospinal fluid has a hemoglobin reaction.

Description

technical field [0001] The invention relates to an intelligent cerebrospinal fluid drainage control and identification warning system, which belongs to the medical equipment used by medical units. Background technique [0002] Postoperative cerebrospinal fluid drainage refers to placing a drainage tube into the ventricle or lumbar spinal canal (lumbar cistern) to continuously drain cerebrospinal fluid. First, it can reduce intracranial pressure, and second, it can promote the discharge of inflammatory cerebrospinal fluid, so as to clean the cerebrospinal fluid and assist treatment. Inflammation of the ventricles. For cerebrospinal fluid leakage, the drainage volume must be strictly controlled to avoid excessive drainage volume from further aggravating the symptoms of intracranial hypotension, and even serious complications such as epidural hemorrhage and cerebral hernia, which endanger the life of the patient. At present, negative pressure drainage balls / bottles are usually...

AI Technical Summary

Problems solved by technology

The disadvantage of this drainage method is that it cannot automatically control the daily drainage volume, and medical personnel need to check and measure it repeatedly, which is labor-intensive.

If only the total amount of daily drainage is controlled, but too fast flow rate or excessive drainage per unit time will also cause clinical risks such as low intracranial pressure and epidural hemorrhage. CN103990188A proposes to control drainage by preset pressure flow, but it can not solve the problem of drainage control; CN106963998A adopts the automatic quantitative control method of floating ball connection circuit for drainage, but it cannot realize the control of discharge time and drainage speed, and there are still relatively large defects and risks
