Description
Technical field
The present invention relates to mice Olfactory behavior technical field of experiment equipment, especially a kind of olfactory sensation tester.
Background technology
At present, scientific experiments is the capacitance electrode made according to Kirchhoff's current law (KCL) with the monitor of mice orifice plate olfactory sensation tester.At 400 × 400mm
2lower panels 5 capacitance electrode monitors are housed, the electric charge of electric capacity inside can be caused transfer to occur and produces a kind of analogue signal when animal is near monitor, these signals are collected by collection of simulant signal card and are imported computer into, then change these information into required data by software analysis.Need before using this tester to test mice olfactory sensation to regulate the sensitivity of each capacitance monitor of instrument, output signal due to monitor is analogue signal, therefore very accurately can not define the boundary of mice nose access aperture, the inspecting hole time and the number of times that are recorded to mice will have error.This external test phase, buttocks or front and back limb can stretch in hole by some animals, and this can cause Charger transfer equally, and machine is mistaken in the head access aperture of mice.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, propose a kind of olfactory sensation tester, can accurate recording mice inspecting hole time and number of times, and the erroneous judgement caused because detector is stretched at other positions of mice is avoided by the design of pedal pause switch.
In order to realize foregoing invention object, the invention provides following technical scheme:
A kind of olfactory sensation tester, comprise the multiple test cells be arranged on housing, multiple described test cell is connected in parallel, each described test cell comprises Photoelectric infrared switch, enumerator, timer and odor bottle, described Photoelectric infrared switch is that cylindrical shape is enclosed within described odor bottle top, around described Photoelectric infrared switch inside, multiple switch element be connected in parallel is installed, each switch element is made up of staggered relatively emitter stage and a receiving pole, receiving pole described in each of each test cell is connected with the described enumerator in this test cell and described timer, when the infrared ray in described switch element is truncated, described enumerator counts once timer and starts timing.
Further, each described switch element also comprises a probe display lamp, and this probe display lamp is arranged on described receiving pole, and when described in certain, the infrared ray of switch element is truncated, corresponding described probe display lamp is bright.
Further, each described test cell also comprises a passage display lamp and a channel switching, described passage display lamp is connected with described channel switching with after corresponding described Photoelectric infrared switch parallel connection, and when described in certain, channel switching closes, corresponding described passage display lamp is bright.
Further, also comprise total power light, this total power light is in parallel with test cell described in each, and when total power switch closes, this total power light is bright.
Further, connect with pause switch after test cell parallel connection described in each and be connected with total power switch again.
To the use of HONGGUANG electric switch, a kind of olfactory sensation tester of the present invention, ensure that tester records mice inspecting hole time and number of times accurately, the use of pause switch is avoided to the erroneous judgement caused because detector is stretched at other positions of mice.

Fig. 3 is the circuit diagram of a kind of olfactory sensation tester of the present invention.
Detailed description of the invention
Describe the present invention below in conjunction with accompanying drawing, the description of this part is only exemplary and explanatory, should not have any restriction to protection scope of the present invention.
A kind of olfactory sensation tester as Figure 1-3, be arranged on the multiple test cells 15 on housing, in the present embodiment we preferably 5 test cells, 15,5 test cells 15 be connected in parallel, each test cell 15 comprises Photoelectric infrared switch, enumerator 11, timer 12 and odor bottle 3.
Photoelectric infrared switch is that cylindrical shape is enclosed within odor bottle 3 top, and odor bottle 3 is arranged on its underpart erecting bed 5, is provided with spring 4 between odor bottle 3 and erecting bed.
Above Photoelectric infrared switch, install the stainless steel faceplate 2 having 5 holes, the position of these 5 holes is corresponding with the position of below Photoelectric infrared switch.
Politef panel 1 is installed above stainless steel faceplate 2, this politef panel 1 can have the hole 11 of different number according to different experimental selection, one, two, four can be opened, or five, the position of hole 11 is corresponding with the position of corresponding Photoelectric infrared switch.
Be provided with multiple switch element be connected in parallel around Photoelectric infrared switch inside, the present embodiment installs 9 switch elements, and each switch element is made up of staggered relatively emitter stage 161 and a receiving pole 162,
Each receiving pole 162 of each test cell 15 is all connected with the enumerator 11 in this test cell 15 and timer 12, and when the infrared ray in switch element is truncated, corresponding counter 11 counts once, and corresponding timer 12 starts timing.
Each switch element also comprises a probe display lamp 14,
This probe display lamp 14 is arranged on receiving pole 162, and display lamp 14 of popping one's head in accordingly when the infrared ray of certain switch element is truncated is bright, and whether this probe display lamp 14 can be used for detection probe and can normally use.
Each test cell 15 also comprises a passage display lamp 10 and a channel switching 13,
Passage display lamp 10 is connected with channel switching 13 with after corresponding Photoelectric infrared switch parallel connection, and when certain channel switching 13 closes, corresponding passage display lamp 10 is bright.
