Abstract
The invention discloses a kind of multiple recording system of activity nictation for accurately measuring human or animal, comprise the transformator that AC supply voltage is reduced, low-voltage AC power supply is become the current rectifying and wave filtering circuit of DC source, launch ultrared infrared-emitting diode, the infrared receiving diode of receiving infrared-ray, and the circuit that can produce the change of corresponding output current for the resistance variations of infrared receiving diode.When eyelid is movable, the infrared light intensity that eyelid reflects can change, the resistance of infrared receiving diode is caused to change, then the both end voltage of the measuring resistance of connecting with infrared receiving diode is caused to change, the change in voltage at fixed resistance two ends is measured by physiograph, can indirect inspection activity nictation.This system can not only be measured activity nictation accurately and stably, and there is good Time and place resolution, eyelid activity itself had no effect, easy and simple to handle, be quick on the draw, can the advantage such as work by multichannel simultaneously.
Description
Technical field
The invention belongs to physiological Study instrument and equipment technical field, be specifically related to one movable multiple recording system nictation based on infrared emission reception technique, be particularly useful for the reflexive nictation of humans and animals and cognitive and psychology, learning and memory behavior correlational study.
Background technology
Cornea not only can be protected nictation not by exterior injury and stimulation, and have close relationship with cognitive process and some diseases.Reflexive provides a simple eye-blink model to study complicated activity nictation nictation.Cerebral cortex, ganglion basal, cerebellum etc. all adjust reflexive nictation, such as a kind of ganglion basal dysfunction and the disease that causes, parkinson, improves the frequency of reflexive nictation, but reduces the frequency of spontaneous nictation.Central nervous mechanisms also for enquiry learning memory while that reflexive being blinked has opened up a new approach.Such as the neurobiological mechanism of the acquisition of winking reflex, maintenance and extraction is inquired in a large amount of behavioristicss and psychologic research.At present, have a lot of method measuring activity nictation, but neither one is desirable.Conventional measuring method one directly measures eyelid position by tonotransducer, and two is the myoelectrical activity indirect inspection eyelid positions by record eyelid flesh.But these two kinds of methods have potential problems, the interference of eyelid active receiving machinery, sensitivity is not high, and facial muscle activity can bring interference, and has damage etc. in recording process, can not be used for activity inventory nictation of people.
Summary of the invention
In order to solve movable measuring device overslaugh existing nictation eyelid movement, sensitivity is not high, facial muscle activity can bring interference, has the deficiencies such as damage in recording process, the invention provides movable multiple recording system a kind of nictation based on infrared emission reception technique.This system can not only be measured activity nictation accurately and stably, and there is good Time and place resolution, eyelid activity itself had no effect, easy and simple to handle, be quick on the draw, can the advantage such as work by multichannel simultaneously.
It is as follows that the present invention solves the technical scheme adopted:
Based on an activity nictation multiple recording system for infrared emission reception technique, it comprises transformator, current rectifying and wave filtering circuit, and infrared receiver sends diode and resistance.The input of described transformator connects alternating current power supply, and alternating current power supply by transformer pressure-reducing, it exports and connects current rectifying and wave filtering circuit, by becoming DC source after current rectifying and wave filtering circuit, then connects infrared receiver, transmission diode and resistance.After described infrared receiving diode is connected with a measuring resistance and the overall parallel connection of infrared-emitting diode and protective resistance; the two ends of measuring resistance connect the signal input of physiograph; form road activity inventory passage nictation, movable multiple recording system passage parallel connection formation nictation that multichannel is such.
This recording system is that alternating current power supply is passed through transformer pressure-reducing, again by becoming DC source after current rectifying and wave filtering circuit, then be defeated by and send activity inventory passage of blinking, the infrared ray radiation that infrared-emitting diode sends is on eyes, when eyelid is movable, the light that eyelid reflects can change, the resistance of infrared receiving diode is caused to change, then measuring resistance two both end voltage of connecting with infrared receiving diode is caused to change, measure the change of fixed resistance two terminal voltage by physiograph, just can indirectly measure activity nictation.
Structure of the present invention is simple, can not only measure activity nictation accurately and stably, and there is good Time and place resolution, eyelid activity itself had no effect, easy and simple to handle, be quick on the draw, can the advantage such as work by multichannel simultaneously.

Detailed description of the invention
Structure of the present invention is described in detail below in conjunction with accompanying drawing:
The present embodiment is for 4 passages, and see Fig. 1, this multiple recording system comprises transformator, current rectifying and wave filtering circuit, infrared receiver, transmission diode and resistance etc.The input of transformator connects alternating current power supply, and alternating current power supply by transformer pressure-reducing, it exports and connects current rectifying and wave filtering circuit, by becoming DC source after current rectifying and wave filtering circuit, then connects infrared receiver, transmission diode and resistance.After infrared receiving diode 3 is connected with a measuring resistance 1 and infrared-emitting diode 4 and the overall parallel connection of the protective resistance 2 of connect; the two ends of measuring resistance connect the signal input of physiograph; form road activity inventory passage nictation, movable multiple recording system passage parallel connection formation nictation that four roads are such.
See Fig. 2, this multiple recording system is realized by an instrument, and the control panel of instrument can arrange switch, 4 input ports and 4 delivery outlets.
See Fig. 3, in concrete manufacture process, by cable 6, infrared receiving diode 3 and infrared-emitting diode 4 are separated from instrument internal, parallel connection is positioned over eyes 5 front, for measuring activity nictation.
Wherein, physiograph is existing instrument, produces RM6240 multichannel physiograph etc. as adopted Chengdu Instruement Factory.
