2s s0 3j DETAILED DEc~r;;RIPTTON OF THE PREFERRED EMBODIMENTS ;
A preferred embodiment of the bracelet thermometer of the present invention i.s illustrated in Fig. l, and s is generally identified by the reference 1.
Bracelet 2 includes a metallic containing case 3 with a generally flat bottom surface 4 for good contact with humam wr.i.st. As shown in Fig. 1A, which shows a to cross-sectional side view, a temperature sensing thermistor 5 is attached to inside bottom of case 3.
Body temperature transmitted through metallic case 3 is thus picked up by thermistor 5. Thermistor 5 is connected t.o an electronic circuitry 6, which in turn l~ is connectec.~ to a LCD 7 to display the temperature measured. A small battery cell 8, also housed inside the case supplies power to the electronic circuitry.
To alert the bearer of any abnormal body 2( temperature, the bracelet thermometer is preferably equipped wino an alarm feature. Beeper 9, controlled by electronic circuitry 6, will produce an alarm sound wheYi an abncormally high temperature is detected.
25 Sinr_.e wrist, leg, armpit and different body parts may show different 'body temperatures normally, it is desirable ~:hat the alarm temperature can be preset by the wearer. F'or this purpose, alert setting switch IO
is provided as shown. Choice of Centigrade or 30 Fahrenheit may also be effected by Switch 10, or by another separate switch as desired (not shovan) .
Another preferred embodiment is shown in Fig. 2.
In this e~r_bodiment, a sheet of temperature sensitive 3s liq~.id cr~~°stai digital display 11 is attached to inside bottom of metallic case 1~~ of bracelet 13. Both display 11 ar-Ld case 12 are preferably rectangular, so that display 11 can be sectioned into a serious of bracl~~ets to show consecutive temperature readings. When body temperature is transmitted through the metallic i case 12 to display 11, the bracket corresponding to the specific temperature becomes visible. The brackets are numbered with digits showing the correct temperatures, and preferably different background colours are employed for' different brackets for easy perception.
to Fig. 3 shows another preferred embodiment in which mercury is employed as sensing element. A small conventional. mercury thermometer with glass bulb 14 and a coil tubing 15 is placed in metallic case 16 of 15 bracelet 17. Beneath coil tubing 15 is a circular scale sheet 18 graduated with proper temperature readings. Bulb 14 containing proper amount of mercury is embedded to inside bottom of case 16 so that body temperaturE~ can be easily transmitted to bulb 14.
2t) Fig. 4 shows a preferred embodiment similar to Fig. 3, ex_c:ept that alcohol is used instead of mercury.
A glass bulb 19 with coil tubing 20 containing proper amount of coloured alcohol is placed inside metallic 2s case 21 of bracelet 22. Beneath coil tubing 20 is a scale sheen ~'3 to provide proper temperature reading.
Bulb 19 is in direct contact with bottom of case 21, and therefore measures body temperature transmitted through case 21.
:30 Another preferred embodiment as shown in Fig. 5 employs bimetallic spring for temperature measuring.
Fig. 5A shows a cross-sectional side view. A
temperature sensitive bimetallic spring 25 is connected 3i to inside bottom of metallic case 24 of bracelet 26.
Bimetallic spring 25 controls movement of pointer 27 which travels on circular locus above a circular scale sheet 28 with proper temperature graduations. Body temperature transmitted through case 24 effects bias to bimetallic spring 25, which in turn acts on pointer 27 to settle on its proper position to indicate correct body temperature.
Fi.g. E~ shows another preferred embodiment capable of displaying both temperature and time simultaneously.
With a temperature/timing dual function electronic circuitry, body temperature and real time is displayed by upper display 29 and lower display 30 respectively.
Selective switch 31 is for choice of timer function and real time cJlock. It is of course possible that only IS one display is used. In this latter case, switch 31 is for sequential selection of body temperature, clock and timer.
To measure temperature of body parts that cannot be easily visible, e.g. armpit, it may be desirable that. the display is farther away from the point of measurement. Fig. 7 shows another preferred embodiment where bracelet 39 consists of buckles 32. Thermistor 33 is embedded inside buckle 32, and connected by wires 34 to electronic circuitry 35 which is inside circular case 36 together with battery 37 and display 38. With buc~_le 32 located in the armpit, armpit temperature can thus be easily seen from display 38 on the outside arm.
It is her eby recapitulated that above embodiments are for illustrations only. Thus whilst metallic cases are cited becal.zse of generally good heat conduction, any material good for the purpose may be substituted.
Similarly, any proper temperature sensing elements and 3> displays capable of serving the purposes may also be substituted and are within scope of this invention.
