The specific embodiment
Please refer to Fig. 6, it shows an embodiment of temperature indicating device in clinical thermometer of the present invention.It discloses a temperature display section 10a, comprises that a heat-conducting layer is to receive hot-fluid.One temperature scale layer 20, is positioned at temperature display section 10a surface or its top position.One heat discoloration layer 30, at least be formed on temperature display section 10a, wherein heat-conducting layer can be guided above-mentioned hot-fluid to the heat discoloration layer 30 on temperature display section 10a, heat discoloration layer 30 produces a transformation region 30X according to the corresponding temperature of hot-fluid, with temperature scale corresponding on displays temperature scale layer 20, remaining not transformation region 30Y maintain primitive color.
Please also refer to Figure 1A, Figure 1B figure and Fig. 5, in one embodiment, clinical thermometer comprises a sensing member 15, has thermal interface 43, one temperature display section 10a, in abutting connection with sensing member 15.One heat discoloration layer 30, at least be formed on temperature display section 10a, the temperature on sensing member 15 sense heat contact surfaces 43 wherein, with conductive heat flow to the heat discoloration layer 30 on temperature display section 10a, heat discoloration layer 30 produces a transformation region according to the corresponding temperature of hot-fluid, with temperature scale corresponding on displays temperature scale layer 20.In one embodiment, sensing member 15 can consist of single heat-conducting layer, and usings heat-conducting layer as the 10b of sensible heat portion, and sensible heat portion surface is thermal interface.And in another embodiment, sensing member 15 can more comprise that an end member 41 is to be coated the above-mentioned sensible heat 10b of portion, but it is not as limit.
In addition, protection member 40, for example, be a transparent bodies, and it can consist 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 hollow metal pipe body, another user for convenience measures body temperature and avoids injury, and the leading section surface of end member 41 can be smooth curve shape.In addition, end member 41 inside can select to be filled to small part heat-conducting glue with the heat-conducting layer 10 of fixing follow-up insertion as the position of the 10b of sensible heat portion.
Secondly; 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 section 10a; the 10b of sensible heat portion is arranged in end member 41; temperature display section 10a 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 consists of the metal material of high-termal conductivity.In one embodiment, on the leading section of the 10b of sensible heat portion butt end member 41 or the medial wall of end member 41.In addition; temperature scale layer 20, for example, used waterproof ink, can each temperature value of mint-mark in temperature display section 10a surface or its top of heat-conducting layer 10; as shown in Figure 6, each temperature value of mint-mark is in the position of protection member 40 inner surfacies or outer surface corresponding temperature display part 10a for example.
Please again consult Figure 1B, heat discoloration layer 30 is at least formed on the temperature display section 10a of heat-conducting layer 10.The 10b of the sensible heat portion sense heat contact surface 43 on heat-conducting layer 10 wherein, with conductive heat flow to the heat discoloration layer 30 on temperature display section 10a.Heat discoloration layer 30 can produce according to the corresponding temperature of hot-fluid a transformation region 30X, and with temperature scale corresponding on displays temperature scale layer 20, the remainder 30Y of heat discoloration layer 30 does not reach not variable color of marginal value because of temperature, therefore still maintains primitive color.
Wherein, can select to be adjacent to the 10b of sensible heat portion with the lower temperature scale value 30a of the upper temperature scale layer of temperature display section 10a, and with higher temperature scale value 30n away from the 10b of sensible heat portion.For example, heat discoloration layer 30 can be divided into the block 30a～30n of a plurality of each temperature scale of correspondence, each block be take respectively each temperature scale as minimum critical value of discoloration, therefore when the 10b of sensible heat portion conductive heat flow is during to heat discoloration layer 30 on temperature display section 10a, the corresponding temperature of hot-fluid can make the block of each below the temperature variable color and form transformation region at this of minimum critical value of discoloration, as shown in Figures 5 and 6, when recording temperature, be Celsius 37 while spending, can make critical value of discoloration each block below 37 degree change color and form transformation region 30X; Critical value of discoloration each block more than 37 degree remains unchanged.Wherein, the primitive color of heat discoloration layer 30 can reduce the identification of temperature scale, and color after the change of transformation region can be another kind of color or form transparent region to know displays temperature scale value.
Referring again to Figure 1A and Figure 1B, in one embodiment, heat discoloration layer 30 selects independently have the heat discoloration piece 30a～30n of different critical temperature value by each, to be attached on each block as the mode of steel plate printing or coating.
Yet in another embodiment, as shown in Figure 2 A and 2 B, heat discoloration layer 30 also can be comprised of multiple structure, wherein, heat discoloration layer 30 has the block of higher critical value of discoloration as 30n, and its thickness is thicker.
In addition,, as shown in Fig. 3 A and Fig. 3 B, the multiple structure of heat discoloration layer 30 also can be selected to be comprised of the thin film of multilamellar different components or doping different proportion.
Refer to Fig. 4 A and Fig. 4 B, in the present embodiment, have the more block of multiple structure, its critical value of discoloration is higher, that is the variable color that needs higher temperature to make.For example, can first be coated with one deck heat discoloration thin film in heat-conducting layer 10 surfaces, scope can at least contain whole temperature scale layer, secondly, be coated with the 2nd layer of heat discoloration thin film in heat-conducting layer 10 surfaces, but scope only contains the 2nd more than temperature scale region, the rest may be inferred.Therefore, the heat discoloration thin film number of plies of minimum temperature scale block (30a) is minimum, and the heat discoloration thin film number of plies of maximum temperature scale block (30n) is maximum.
Comprehensively above-mentioned, because the clinical thermometer of the present embodiment is containing hydrargyrum, therefore can avoid toxic pollution, cost significantly reduces compared with electronic clinical thermometer simultaneously, this clinical thermometer need not arrange chemical battery in addition, except avoiding environmental pollution, also can prevent that clinical thermometer from need not cause chemical battery loss because being long placed in, power shortage while causing using.
