The specific embodiment
Please be simultaneously with reference to figure 1-3, it shows an embodiment of clinical thermometer of the present invention.Clinical thermometer 50 comprises a sensing member 15, has a thermal interface 43, one temperature display part 10a, in abutting connection with sensing member 15.One heat discoloration layer 30; At least be formed on the temperature display part 10a; The temperature on the sensing member 15 sense heat contact surfaces 43 wherein; With the heat discoloration layer 30 on conductive heat flow to the temperature display part 10a, heat discoloration layer 30 produces a transformation region according to the corresponding temperature of hot-fluid, with temperature scale corresponding on the displays temperature scale layer 20.In one embodiment, sensing member 15 can be made up of single heat-conducting layer, and with heat-conducting layer as the 10b of sensible heat portion, sensible heat portion surface then is a thermal interface.And in another embodiment, sensing member 15 can more comprise an end member 41 coating the above-mentioned sensible heat 10b of portion, but it is not as limit.
In addition, as shown in Figure 3, protection member 40 for example is a transparent bodies, and it can be made up of glass or plastic body, and generally speaking, protection member 40 is a hollow tube.End member 41 has a thermal interface 43, and it is fixed in protection member 40.And in one embodiment, for alleviating thermal capacity, end member 41 forms with the hollow metal pipe body, and for making things convenient for user to measure body temperature and avoiding injury, the leading section surface of end member 41 can be the smooth curve shape in addition.In addition, few part heat-conducting glue can be selected to be filled to the heat-conducting layer 10 of the fixing follow-up insertion position like the 10b of sensible heat portion in end member 41 inside.
Secondly; See also Fig. 1 and Fig. 6, heat-conducting layer 10 comprises a 10b of sensible heat portion, in one embodiment; Sensible heat portion can stretch out and form a temperature display part 10a; The 10b of sensible heat portion is arranged in end member 41, and temperature display part 10a then is arranged in protection member 40, and heat-conducting layer 10 can be heat conducting film or the thermal paper that one deck for example is made up of the metal material of high-termal conductivity.In one embodiment, on the medial wall of the leading section of the 10b of sensible heat portion butt end member 41 or end member 41.In addition, temperature scale layer 20 for example uses waterproof ink; Can be as shown in Figure 1; Each temperature value of mint-mark is on the temperature display part 10a of heat-conducting layer 10, and is perhaps as shown in Figure 6, and each temperature value of mint-mark is in the position of protection member 40 inner surfacies or outer surface corresponding temperature display part.
See also Fig. 2 and Fig. 4, heat discoloration layer 30 is formed on the temperature display part 10a of heat-conducting layer 10 at least.The 10b of the sensible heat portion sense heat contact surface 43 on the heat-conducting layer 10 wherein is with the heat discoloration layer 30 on conductive heat flow to the temperature display part 10a.As shown in Figure 4; Heat discoloration layer 30 can produce a transformation region 30X according to the corresponding temperature of hot-fluid; With temperature scale corresponding on the displays temperature scale layer 20, therefore the remainder of heat discoloration layer 30 not transformation region 30Y still keeps primitive color then because of temperature does not reach not variable color of marginal value.
Wherein, among the embodiment as shown in Figure 2, the lower temperature scale value (heat discoloration block 30a) that can select to go up the temperature scale layer with temperature display part 10a is adjacent to the 10b of sensible heat portion, and with higher temperature scale value (heat discoloration block 30n) away from the 10b of sensible heat portion.For example; Heat discoloration layer 30 can be divided into the heat discoloration block 30a～30n of a plurality of each temperature scale of correspondence; Each block is minimum critical value of discoloration with each temperature scale respectively then; Therefore when the heat discoloration layer 30 of the 10b of sensible heat portion conductive heat flow to temperature display part 10a, the corresponding temperature of hot-fluid can make minimum critical value of discoloration this below temperature each block variable color and form transformation region, like Fig. 4 and shown in Figure 5; When recording temperature and be 37 degrees centigrade, can make critical value of discoloration change color and form transformation region 30X at each block below 37 degrees centigrade; Critical value of discoloration then remains unchanged at each block more than 37 degrees centigrade.Wherein, the primitive color of heat discoloration layer 30 can reduce the identification of temperature scale, and the color after the change of transformation region can be another kind of color or form transparent region to know the displays temperature scale value.
Please consult Fig. 2 again, in one embodiment, heat discoloration layer 30 is selected to be formed on each block with the mode like steel plate printing or coating by each heat discoloration piece that independently has the different critical temperature value.Yet in another embodiment, heat discoloration layer 30 also can be made up of multiple structure, has the more block of layer structure, and its critical value of discoloration is higher, and the high temperature that also promptly need heal can make it variable color.For example, can be coated with one deck heat discoloration thin film earlier in heat-conducting layer 10 surfaces, scope can contain whole temperature scale layer at least; Secondly; Coating second layer heat discoloration thin film is in heat-conducting layer 10 surfaces, but scope only contains the above zone of second temperature scale, and the rest may be inferred.Therefore, the heat discoloration thin film of minimum temperature scale block (heat discoloration block 30a) is the thinnest, and the heat discoloration thin film of maximum temperature scale block (heat discoloration block 30n) is the thickest.In addition, the multiple structure of heat discoloration layer 30 also can be selected to be made up of the thin film of multilamellar different components or doping different proportion.
Comprehensively above-mentioned; Because the clinical thermometer of present embodiment does not contain hydrargyrum, therefore can avoid toxic pollution, cost significantly reduces than electronic clinical thermometer simultaneously; This clinical thermometer need not be provided with the chemical battery in addition; Except that avoiding the environmental pollution, can prevent that also clinical thermometer from need not cause the chemical battery loss because of putting for a long time, power shortage when causing using.
