Technical Field
The utility model relates to a cerebrospinal fluid drainage speed detects technical field, especially relates to a cerebrospinal fluid drainage speed monitoring devices based on capacitanc sensor.
Background
At present, clinical detection and control of cerebrospinal fluid drainage speed can only depend on nursing strict observation basically, medical staff judge whether drainage speed is suitable or not by observing drainage volume of a patient every 1 hour or 30 minutes, and the change of the body position of the patient or the instantaneous fluctuation of intracranial pressure can cause the instantaneous change of the drainage speed, so that the medical staff cannot monitor the change of the flow speed in real time. The expected treatment effect is difficult to achieve by too fast and too slow drainage in the drainage process, and even the nursing safety is influenced.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a drainage speed monitoring devices that can real-time detection cerebrospinal fluid drainage speed.
In order to achieve the above purpose, the utility model provides a cerebrospinal fluid drainage speed monitoring device based on a capacitive sensor, which comprises a liquid storage tube, a capacitive sensor, a solenoid valve, a liquid storage bag and a control circuit;
the capacitance sensor is arranged on the outer wall of the liquid storage pipe and is used for sensing the change of the internal flow of the liquid storage pipe; the liquid storage pipe is communicated with the liquid storage bag through a pipeline, and the electromagnetic valve is preset on the pipeline; the electromagnetic valve and the capacitance sensor are both electrically connected with the control circuit.
Furthermore, the capacitance sensor is composed of two coplanar electrode plates, and the two electrode plates are arranged on one side of the liquid storage pipe.
Furthermore, the control circuit comprises a circuit conversion module, a micro signal processor and a display;
the capacitance sensor is electrically connected with the micro signal processor through the circuit conversion module, and the micro signal processor is electrically connected with the display and the electromagnetic valve.
Furthermore, the liquid inlet of the liquid storage pipe is arranged at the top of the liquid storage pipe and is communicated with the liquid drainage equipment.
Compared with the prior art, the utility model has the advantages that: the utility model discloses a change the ingenious electric capacity change volume that becomes capacitive sensor with the inside cerebrospinal fluid capacity of stock solution pipe into, turn into the electric signal of telecommunication with electric capacity change volume again, handle the back through micro signal processor, turn into corresponding drainage velocity value to fine solution medical personnel can not the problem of real-time supervision cerebrospinal fluid drainage speed clinically, the utility model discloses guaranteed the real-time of monitoring, improved liquid level monitoring system's detection precision and interference killing feature with capacitive sensor. Meanwhile, the drainage liquid can be automatically discharged by adopting the control of the electromagnetic valve, so that the waste of manpower is avoided, and the design concept of automation is met.

Fig. 1 is a schematic view of the overall structure of the cerebrospinal fluid drainage speed monitoring device based on the capacitive sensor in the embodiment of the present invention.
Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be further described below.
As shown in fig. 1, the utility model provides a cerebrospinal fluid drainage speed monitoring device based on a capacitive sensor, which comprises a liquid storage tube 1, a capacitive sensor 2, a solenoid valve 3, a liquid storage bag 4 and a control circuit;
the capacitance sensor 2 is arranged on the outer wall of the liquid storage pipe 1 and is used for sensing the flow change in the liquid storage pipe 1; the liquid storage pipe 1 is communicated with the liquid storage bag 4 through a pipeline, and the electromagnetic valve 3 is preset on the pipeline; the electromagnetic valve 3 and the capacitance sensor 2 are connected with a control circuit.
In this embodiment, the capacitive sensor 2 is two coplanar electrode plates, and the two coplanar electrode plates are disposed on one side of the liquid storage tube.
In the embodiment, the control circuit comprises a circuit conversion module, a micro signal processor and a display;
the capacitance sensor 2 is connected with a micro signal processor through a circuit conversion module, and the micro signal processor is connected with a display and an electromagnetic valve 3.
In this embodiment, the liquid inlet of the liquid storage tube 1 is arranged at the top of the liquid storage tube 1 and is communicated with the liquid drainage device.
In this embodiment, the utility model discloses monitoring device's theory of operation does: the liquid drainage device drains cerebrospinal fluid into the liquid storage pipe 1 in real time, the cerebrospinal fluid capacity inside the liquid storage pipe 1 changes in real time, at the moment, the capacitance between electrode plates arranged on one side of the liquid storage pipe 1 also changes, the variable quantity of the capacitance transmits the converted signal to the micro signal processor through the circuit conversion module, and the received electric signal is converted into a corresponding drainage speed to be output on a display through presetting a corresponding model between voltage and drainage speed inside the micro signal processor, so that the medical staff can observe the drainage speed visually; when the cerebrospinal fluid of 1 inside of liquid storage tube is about to reach the range scope, when the capacitance value of 2 inside of capacitive sensor is about to reach the predetermined value promptly, micro signal processor control solenoid valve 3 is opened, keeps the leading-in liquid storage bag 4 of 1 inside liquid storage tube to unloading liquid storage tube 1, the cerebrospinal fluid of being convenient for continues to be leading-in.
The above description is only for the preferred embodiment of the present invention, and does not limit the present invention. Any technical personnel who belongs to the technical field, in the scope that does not deviate from the technical scheme of the utility model, to the technical scheme and the technical content that the utility model discloses expose do the change such as the equivalent replacement of any form or modification, all belong to the content that does not break away from the technical scheme of the utility model, still belong to within the scope of protection of the utility model.
