The superiorities of the utility model lie in that firstly, the utility model has ingenious and practical design, realizes the automatic monitoring, lightens the work load of medical staffs, and enhances the working efficiency and medical treatment quality, secondly, the utility model has simple conformation, convenient utilization, low manufacturing cost and excellent clinical exploitation significance.
Description
(1) technical field:
This utility model relates to a kind of medical apparatus and instruments, particularly is applied in a kind of ICP lower ventricle external drainage automaton of neurosurgery.
(2) background technology:
Intracranial pressure (ICP) monitoring be adopt and monitor continuous measurement ICP with the method for observation ICP dynamic change.Can understand the state of ICP such as intracranial mass lesion, cerebral trauma, cerebral edema, hydrocephalus, be worth having than restricted publication of international news and commentary entitled aspect diagnosis, guidance and the judging prognosis.The Intraventricular intubation is accurate, the most reliable ICP monitoring method at present, and clinical practice is wider.It is also advantageous in that the external drainage that can guarantee curative Intraventricular cerebrospinal fluid, alleviates cerebral edema thereby reduce intracranial pressure; Draining courageous and upright cerebrospinal fluid alleviates cerebral vasospasm and reduces hydrocephalic sickness rate.But need medical personnel's close observation intracranial pressure (ICP) to change clinically, in time the EVD bottle is opened, close the drain switch after draining the part cerebrospinal fluid, continue intracranial pressure (ICP) monitoring.This process is mixed many anthropic factors, such as medical personnel's degree of fatigue, responsibility etc.
(3) summary of the invention:
The purpose of this utility model is to design a kind of ICP lower ventricle external drainage automaton, it improves existing ICP monitor, increases the electromagnetic valve control device, makes the automatic control under the EVD realization ICP monitoring, reduce anthropic factor, increase work efficiency.
The technical solution of the utility model: a kind of ICP lower ventricle external drainage automaton, comprise intracrenial pressure monitor, pressure transducer and EVD bottle, the pressure signal outfan that it is characterized in that connecting the pressure transducer of EVD pipe connects the pressure signal input of intracrenial pressure monitor, but the alarm signal output ends of intracrenial pressure monitor connects the electromagnetic valve delay driving circuit, but the control output end of electromagnetic valve delay driving circuit connects an external electromagnetic valve, and the aseptic drainage tube between the ventricles of the brain and EVD bottle is housed in the control valve port of external electromagnetic valve.
Can be between 8-25mmHg between the higher limit monitoring regulatory region of above-mentioned said intracrenial pressure monitor.
But but above-mentioned said electromagnetic valve delay driving circuit adopts existing electromagnetic valve delay driving circuit unit.
Above-mentioned said external electromagnetic valve adopts commercially available common opening and closing formula electromagnetic valve.
Operation principle of the present utility model with work process is: but since between the outfan of the ventricular drainage tube that is being connected pressure transducer and EVD bottle the external electromagnetic valve of being controlled by the electromagnetic valve delay driving circuit of having installed, so having replaced needs medical personnel's close observation intracranial pressure (ICP) to change and by the present situation of controlling the EVD switch manually clinically, formation is based on existing intracranial pressure (ICP) monitor, increased the electromagnetic valve automaton, make the switching of EVD pipe send signal to intracrenial pressure monitor by pressure transducer, but send by intracrenial pressure monitor again and drive signal to the electromagnetic valve delay driving circuit, but send valve opening solenoid by the electromagnetic valve delay driving circuit more at last, the control signal of closing reaches the control to the switching of EVD pipe, thereby finishes the drain work to the part cerebrospinal fluid.Intracranial pressure (ICP) set higher limit monitoring regulatory region between can be between 8-25mmHg, concrete condition can be determined according to patient status by the doctor.
Superiority of the present utility model is: the practicality that 1, is skillfully constructed, realized monitoring automatization, and alleviated medical personnel's work load, improved work efficiency and quality of medical care; 2, simple structure, easy to use, cost of manufacture is low, and good clinical exploitation meaning is arranged.
