Abstract

The utility model discloses an electronic thermometer with automatically showing and reporting temperature for measuring temperature of human body, which comprises an A/D convertor ICL7107, a memorizer (ROM), a compiler (DECODER) an acoustic horn a digital display, a senistor, etc. The utility model transmission transports the temperature of human body to the A/D convertor ICL7107 through the senistor, the temperature of human body is transduced to language by the elements which are mentioned, and the measured temperature data is reported through acoustic horn by human language. The utility model has the advantages of high precision, small size, convenient operation, low cost and timely temperature report. The utility model is suitable for ordinary family and hospital and is especially suitable for monitoring the body temperature of patient.

Description

Electronic thermometer with auto showing and reporting temp. function

The utility model relates to a kind of instrument that is used to measure human body temperature.

The existing instrument that is used for the human body temperature measurement is generally liquid level formula thermometer or dial thermometer.This class thermometer needs to go to declare with eyes the temperature data of accurate gained, and for having defective vision or can the user, just seeming has been not suitable for.In order to solve the deficiency that the said temperature meter exists, U.S. Pat 4428685 discloses a kind of with the instrument of thermo-responsive IC as thermometric, and the data of the human body temperature that this survey instrument can record it are in time quoted with human language.But this is designed to multi-functional facility, and volume is bigger, not too be fit to patient and use at any time, and inside is a central little electric treatment system, and complex structure, the technical requirement height, manufacturing cost is also high.

The purpose of this utility model is to provide a kind of simple in structure at the deficiency that the said temperature survey instrument exists, low cost of manufacture, be suitable for apply can the displays temperature data; Can report the electronic thermometer of temperature again automatically.

Electronic thermometer of the present utility model adopts A/D converter ICL7107, storer (ROM), compiler (DECODER) and elements such as thermistor and loudspeaker.The signal of the human body temperature that ICL7107 receives by thermistor transfers micro voltage again to, becomes temperature reading by the data-switching of its voltage; ROM is a small-capacity memory, and every piece of each attached two bit address (ADDRESS) of this storer, every bit address can be remembered and deposit two seconds kind language, and respectively is furnished with trigger (TRIGGER), when DC pulse was imported, trigger took out the language in the address at once, amplified back input loudspeaker and sounded; Compiler is made up of several pieces of logic gates, this compiler is compiled several output terminals with the signal of ICL7107 output, the corresponding temperature address of each output terminal, when signal produces, the language signal of address output is sent to amplifier immediately, then broadcast language digit, finish the function of report body temperature by loudspeaker.The required power supply of this clinical thermometer is supplied with by 2 pieces of 1.5V batteries.

Advantages such as clinical thermometer of the present utility model has and measures accurately, and the newspaper temperature is timely, and volume is little, and is easy to use, and cost is low are suitable for general family, and hospital uses, and is specially adapted to the mirror of patient temperature is surveyed.

Former reason the following drawings of concrete structure of the present utility model and embodiment provide.

Fig. 1 is the contour structures synoptic diagram of the utility model clinical thermometer;

Fig. 2 is inner each the components and parts connection box arrangenent diagram of clinical thermometer shown in Figure 1;

Fig. 3 is a clinical thermometer components and parts wiring diagram shown in Figure 1.

Embodiment: by A/D converter ICL7107 1, thermistor 7, the bar-shaped automatic demonstration that compiler 2, storer 3, loudspeaker 4, digital indicator 5 are formed and the electronic thermometer 6 of newspaper temperature.The output terminal of A/D converter ICL7107 1 has 22 pins, its front end is connected to thermistor 7, its rear end and digital indicator 5 are connected, and be connected with compiler 2 thus, described compiler 2 is by 5 pieces of logic gate CD4000, CD4001, CD4063, CD4073, CD4081 forms, the logic gate of this compiler 2 can be compiled the temperature signal that ICL7107 1 provides 12 output terminals, the address of the corresponding temperature of each output terminal, and send into temperature storer 3 by 12 output signals that compiler 2 will be compiled, storer 3 is made up of 6 pieces of voice synthesizer UM5000, storer 3 becomes language with the conversion of signals that is received, and be removed immediately and deliver to amplifier, then broadcast language digit, finish the task of report body temperature by loudspeaker 4.The power supply of this clinical thermometer is supplied with by 2 pieces of 1.5V batteries.Present embodiment is sincerely for providing human body temperature take temperature meter, so its measurement range is 32 ℃～43 ℃.

Claims (5)
