Abstract

The utility model relates to an electronic temp. pen which comprises a thermistor (5), a liquid crystal screen (2), an integrated circuit (18), a sensing temperature measuring electronic display device of a reset button (3) and a writing device of a ball-point pen (4). After the reset button (3) is pressed and when the thermistor (5) is contacted with the human body, the change of the temperature is sent to the integrated circuit (18) and the liquid crystal screen (2) shows the digits and then the digits are recorded. The electronic temp. pen makes people quickly and exactly test the body temperature one time.

Description

Electronic temp. pen

The utility model relates to a kind of electronic display unit of sensing testing body temperature and is written as the electric body-temperature pen of one together.

At present, diagnose a disease and nurse when clinical the doctor, mercury clinical thermometer commonly used finishes for twice thermometric work (once provide clinical thermometer, once write down and collect clinical thermometer).Its time of being separated by is all about 5 minutes; When the children of family survey body temperature, also often to break and worry mercurial poisoning for mercury clinical thermometer, this harm to children is very big.When people in test during body temperature, wish can rapid, accurate and disposable finishing more.

The purpose of this utility model designs for realizing above-mentioned hope, promptly be to provide a kind of and carry, thermometric rapidly, numeral is directly perceived and write down electric body-temperature pen easily.It can not only reduce the time of thermometric for the doctor diagnoses a disease, and can also avoid the harm of mercurial poisoning for the children of family.

The purpose of this utility model is achieved in that one, be chosen in the good thermistor of 20～50 ℃ of scope internal linear as sensor, the degree of accuracy of test body temperature reached ± 0.1 ℃; Two, an integrated circuit that can be demonstrated accurate Temperature numerical by the change in resistance of thermistor on liquid crystal display is set, and make the liquid crystal display numeral can one-way, display screen raises with temperature and shows maximum temperature when being thermometric, does not demonstrate the reduction temperature but do not reduce with thermistor temp; Three, a reset button is set, i.e. the switch of automatic shutdown circuit power supply after three minutes.If need the time spent, as long as click button, power supply is by logical, and display screen just shows ambient air temperature at that time, and when treating thermistor contact human body, display screen just shows the temperature of human body, clicks button behind the record again, and display screen shows prevailing circumstances temperature again again; If not the time spent, do not touch the button and to cut off the electricity supply automatically.

Owing to adopt such scheme, can change the temperature that different thermistors is tested different range, also be the electron temperature pen that student experimenting, production and scientific research detect.

Concrete structure of the present utility model is provided by following embodiment and accompanying drawing thereof.

Fig. 1 is the vertical face pie graph of looking of the present utility model;

Fig. 2 is the longitudinal profile pie graph of the utility model (removing the cap for brush);

Fig. 3 is the longitudinal profile pie graph of the utility model body temperature transducing part;

Fig. 4 is the longitudinal profile pie graph of the utility model electronics display part;

Fig. 5 is the A-A cut-open view of Fig. 4;

Fig. 6 is the longitudinal profile pie graph of the utility model garden pearl pen part;

Among the figure, 1, the cap for brush; 2, liquid crystal display; 3, reset button; 4, garden pearl pen; 5, thermistor; 6, metal taper; 7, insulation batching pig pipe; 8, plain conductor; 9, insulation crust; 10, insulated bolt; 11, conductive rubber; 12, insulating carrier plug pipe; 13, button cell; 14, an insulation body shell; 15, the outer shell of an insulation tail; 16, an insulation tailspin changes shell; 17, tube in the pen; 18, integrated circuit; 22, reflecting piece;

In embodiment illustrated in fig. 2, thermistor (5) is fixing between plug pipe (7) at metal taper (6) and insulation, comes sensing by plain conductor (8).Under the power supply output of button cell (13), the integrated circuit (18) of device on insulating carrier plug pipe (12) sends pulse signal, demonstrates numeral by liquid crystal display (2).Yet, because the one-way of liquid crystal display numeral (promptly raising with temperature shows maximum temperature, does not reduce with temperature to show the reduction temperature) just can be convenient to thermistor (5) when leaving human body, liquid crystal display (2) still demonstrates high fever, reaches the purpose of checking temperature.Automatically cut off the electricity supply after three minutes by the device of reset button (3) at last.

Claims

1, a kind of electric body-temperature pen, the sensing thermometric electronic display unit and the garden pearl writing device that comprise thermistor, liquid crystal display, integrated circuit, reset button, it is characterized in that thermistor the metal taper and the insulation every the plug pipe between, by the plain conductor sensing, integrated circuit (IC) apparatus is on insulating carrier plug pipe, and the pulse signal that integrated circuit sends demonstrates numeral by liquid crystal display.

2, electric body-temperature pen according to claim 1 is characterized in that being chosen in the good thermistor of 20-50 ℃ of scope internal linear as sensor.
