Abstract
The utility model relates to an insole type pain threshold tester comprising a tester body. The tester body is provided with a socket that is connected with an insole type heating pad through a plug and a lead, and comprises a power supply, an ampere meter, an indicating lamp, a temperature controller, a timer and a switch that are mutually connected in series, wherein the indicating lamp is connected with a protective resistance in parallel; the temperature controller consists of a variable resistance; and for the insole type heating pad, one surface is provided with viscose glue and the interior is provided with a heating resistance. The insole type pain threshold tester allows the heating pad not to separate from the sole of a mouse in testing, thus avoiding influence on experiment results by the difference between the recording time for tests and the time for actual heating, reducing experimental errors and ensuring scientific and accurate experiments. Besides, the insole type pain threshold tester has the advantages of being simple in structure and low in cost.
Description
Technical field
This utility model relates to a kind of analyzer, specifically relates to a kind of shoe pad formula threshold of pain analyzer that is used for medical science threshold of pain determination experiment.
Background technology
In medicine test and relevant scientific experiment and teaching, normally various pathology and medicinal effects are studied in the reaction of thermostimulation by the test mice, be exactly one of them to the threshold of pain determination experiment of mice.
At present, threshold of pain determinator generally is in the mode of hot plate or light radiation mice to be carried out heat determination.Measure the threshold of pain determinator of mode mainly is made up of hot plate and control section with hot plate, control section is used for controlling temperature and clocks, earlier hot plate is heated to predetermined temperature during experiment, mice is covered on the hot plate with bell glass again, control section picks up counting, because temperature constantly accumulates on the mice sole, to certain degree, mice will be felt the Spurs pain has the physiological reaction of lifting lower limb, at this moment just stop timing, this time just can be reflected the sensitivity of mice to thermostimulation; The threshold of pain determinator of measuring mode with light radiation is that mice is placed in the cover that the bottom surface is a clear glass, and then with the heat radiation lamp according to the mice sole, adopt the mode that manually clocks to clock, the time of manual record similarly is used for weighing the Spurs pain sensitivity of mice.
In the threshold of pain determinator of two kinds of above-mentioned mensuration modes, mice to be determined is in " free movable " and uneasy emotional state always, in the process of heating, mice can ceaselessly be walked about on hot plate, like this, the sole of mice just has the time and the hot plate of part to be in contactless state, and there are tangible gap time and the actual time of being heated of measuring record, the experimental result that this gap is measured the whole threshold of pain has bigger influence, causes experimental result accurate inadequately.In addition, measure with light radiation in the threshold of pain determinator of mode, because the artificial radiation modality that adopts, spotlight may major part all be the edge that has impinged upon sole, heat even inadequately, the error that adding manually clocks produces, apparent especially to the influence of experimental result.
At this situation, design a kind of shoe pad formula threshold of pain analyzer, solve accurate inadequately problem, the urgent needs of medical research just in the determination experiment of the threshold of pain.
Summary of the invention
For overcoming the deficiencies in the prior art, this utility model provides a kind of shoe pad formula threshold of pain analyzer at mice that is used for medical science threshold of pain determination experiment.
The technical scheme that its technical problem that solves this utility model adopts is: a kind of shoe pad formula threshold of pain analyzer, comprise the analyzer body, and it is characterized in that: described analyzer body is provided with socket, and socket is connected with shoe pad formula heating cushion with lead by plug.
Described analyzer body comprises mutual placed in-line power supply, ammeter, display lamp, temperature controller, timer and switch, is parallel with a protective resistance on the display lamp.
Described shoe pad formula heating cushion simultaneously is provided with viscose glue, and inside is provided with heating resistor, and power supply, ammeter, display lamp, temperature controller, timer, the switch of heating resistor and analyzer body are connected in series.
Further, the temperature controller in the described analyzer body is made of variable resistance.
The beneficial effects of the utility model are:
1, the one side that shoe pad formula heating cushion is provided with viscose glue sticks on the mice sole, mice is when " free movable " and uneasy emotional state are walked about in the test, heating cushion still is attached on the mice sole, so just can measure the response time of mice Spurs pain exactly, avoided because of time of measuring record and actual asynchronism(-nization) of being heated influence experimental result, reduce experimental error, guaranteed the science and the degree of accuracy of experiment.
The mathematical relationship of temperature utilizes variable resistance to control temperature during 2, according to electric current and resistance heat balance, makes analyzer simple in structure, with low cost.

The specific embodiment
Below in conjunction with specific embodiment, further set forth this utility model.Should be understood that these embodiment only to be used to this utility model is described and be not used in the restriction scope of the present utility model.Should be understood that in addition those skilled in the art can make various changes or modifications this utility model after the content of having read this utility model instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
In Fig. 1, Fig. 2, a kind of shoe pad formula threshold of pain analyzer comprises analyzer body 4, and analyzer body 4 is provided with socket, and socket is connected with shoe pad formula heating cushion 5 with lead by plug.
Shoe pad formula heating cushion 5 one sides are provided with viscose glue, and inside is provided with heating resistor R, and the power supply E of heating resistor R and analyzer body 4, ammeter A, display lamp L, temperature controller Rx, timer T, K switch are connected in series.
When this utility model uses, the one side that shoe pad formula heating cushion 5 is provided with viscose glue sticks on the mice sole, mice is when " free movable " and uneasy emotional state are walked about, heating cushion still is attached on the mice sole, the temperature controller Rx that adjusting is made of variable resistance is to desired value, K switch is switched to port one, heating resistor R conducting in the shoe pad formula heating cushion 5 also begins heating, timer picks up counting simultaneously, when mice has the physiological reaction of lifting lower limb, K switch is switched to port 2, stops timing and heating, so just can measure the response time of mice Spurs pain exactly.K switch is switched to port 3, can makes that timer makes zero.
