Abstract
The utility model discloses an instrument for sensing and measuring skin temperature, which is formed by the successive connection of a measuring probe, a heat radiator, and an operation box, wherein, a variable wafer and a normal temperature wafer are arranged on the measuring probe; the temperature of the normal temperature is room temperature, the temperature of the variable temperature is controlled by the cool and the thermal reactor of a semiconductor, and displayed in a display. When the utility model is used, the temperature of the variable temperature wafer can be controlled manually, and the utility model can accurately measure the temperature sense sensitivity of skin by the temperature change of the variable temperature wafer, and the temperature comparison of the variable temperature wafer and the normal temperature wafer. The utility model has the advantages of small volume, stable operation, low cost, etc.
Description
The utility model discloses a kind of temperature sensation analyzer, particularly a kind of skin temperature sensory measurement instrument belongs to the medical apparatus class.
At present, the test tubes that different temperatures water is housed of using carry out the responsive mensuration of skin temperature-sensitive to patient more in the hospital, and method is easy, and its shortcoming is that the temperature of water in the test is accurate inadequately, a general result can only be provided, and be difficult to carry out the mensuration of continuous temperature.
The purpose of this utility model provides and a kind ofly can accurately measure skin temperature-sensitive susceptibility, and can carry out continuous temperature and measure skin temperature sensory measurement instrument convenient to use.
The purpose of this utility model is achieved in that skin temperature sensory measurement instrument mainly forms by measuring probe, heating radiator 5 and distribution operation box 8, its design feature is: measuring sonde includes alternating temperature contact 1 and normal temperature contact 6, be separated by with insulator 3 between two contacts, in case pass temperature or be in contact with one another, thermistor 2 and thermistor 9 are housed respectively on alternating temperature contact 1 and the normal temperature contact 6, play the transmission temperature signal, so that on distribution operation box 8, demonstrate Temperature numerical.Alternating temperature contact 1 links to each other with the front surface of the hot and cold heap 4 of semiconductor, so that accept the temperature control of the hot and cold heap of semiconductor; The rear surface of the hot and cold heap 4 of semiconductor links to each other with heating radiator 5, so that as early as possible the heat that produces is left.Distribution operation box 8 also is housed on the heating radiator 5, is provided with power supply, circuit, temperature indicating device and operating switch in the distribution operation box, available hand is held it and is conveniently operated.
Because the utility model has changed traditional method of testing, adopt the hot and cold heap of semiconductor to carry out temperature control, the probe of instrument can carry out continuous temperature as required and change, but design temperature scope again, so the testing precision height, it is little, portable, easy to operate to have volume simultaneously, low cost and other advantages can be promoted the use of.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the utility model sectional structure synoptic diagram;
Fig. 2 is the utility model temperature measurement circuit structural representation;
Fig. 3 is the utility model control circuit structural representation;
Fig. 4 is semiconductor refrigerating, thermal reactor structural representation.
More obvious in order to make semiconductor cold, hot pile produce an effect, alternating temperature contact 1 and half The front surface close contact of the hot and cold heap 4 of conductor; The rear surface of semiconductor cold, hot heap 4 is with diffusing Hot device 5 close contacts, contact adopt metal to make, and be generally good in order to pass temp effect, can adopt With materials such as copper material or stainless steels. Simultaneously in order just to connect more between all parts Good, also had between measuring probe and the radiator 5 fixation in conjunction with mounting head 7.
The semiconductor cold, hot heap is existing public technology, and architectural feature is P-type semiconductor refrigeration Arrange material 18 and N-type semiconductor material of cooling 17 spaces, the two ends of semi-conducting material Copper electrode 16 all is housed, and lead 10 links to each other with electrode respectively, is connected with thermal conductive ceramic on the copper electrode Sheet 15, after lead 10 energisings, the refrigeration one end refrigeration of semiconductor cold, hot heap, an end is sent out Heat, behind the positive and negative electrode that changes energising, the refrigeration end of semiconductor cooling thermal reactor is held mutually with heating Change.
In order to demonstrate the temperature of normal temperature contact 6 and alternating temperature contact 1, the utility model has designed Temperature display circuit 12, this circuit are custom circuit, and operation principle is: Closing Switch K1, Battery pack supplying temperature display system 14 operating voltages, temperature display system passes through thermistor 2 survey the temperature of alternating temperature contact 1, and the temperature of surveying normal temperature contact 6 by thermistor 9 is also aobvious Illustrate.
In order to control the temperature of alternating temperature contact 1, the utility model has designed control circuit 13, This circuit also is custom circuit, and operation principle is: closed reversing switch K2, select refrigeration Or heat, and set the temperature of alternating temperature contact, offer semiconductor cooling thermal reactor RT by battery pack Operating current makes hot and cold heap work, and the effect of refrigeration or pyrogenicity can be by reversing switch K2 Control, for for simplicity, but temperature display circuit 12 and control circuit 13 CB common battery groups, Circuit, temperature indicator and power supply etc. all are contained in the distribution operation box 8. Like this, in test In the process, the normal temperature contact is room temperature, but alternating temperature contact people temperature for a change, by two contacts Observation skin can accurately be judged the temperature-sensitive journey of skin to the susceptibility of temperature behind the contact skin Degree.
Embodiment: alternating temperature contact 1 and normal temperature contact 6 are made with copper product, the face of touching is a strip, and peripheral garden is sliding, thermistor 2 and 9 epoxy glue cementation, be close to respectively on the inside surface of alternating temperature contact 1 and normal temperature contact 6, aggregate erection 7, insulator 3 and distribution operation box 8 usefulness engineering plastics are made.Heating radiator 5 is distributed with heat radiator with the aluminum casting on it, the hot and cold heap of semiconductor adopts 17 pairs of hot and cold heaps of galvanic couple arm.Electric part in the utility model is daily used custom circuit, and its structure is described identical with principle of work and instructions.According to the above, promptly can be made into the utility model.
