Abstract

The utility model discloses an electronic thermometer which can display the human body temperature and have a fever alarm unit, comprising a dial plate-shaped casing. The utility model is characterized in that an integrated temperature sensor whose one end is exposed outside the casing is arranged in the casing; the output end of the temperature sensor is connected with a comparison circuit; the output end of the comparison circuit is respectively connected with the alarm and a temperature diverter; the temperature diverter is connected with an LED driver and a liquid crystal display arranged at the front side of the dial plate; the front side of the dial plate is also provided with an alarm silencing switch. The utility model has the characteristics of reasonable structure, easy use, safety, etc., and the structure is particularly suitable for babies' use.

Description

Electronic thermometer

The utility model belongs to the medical diagnosis instrument, specifically a kind of electronic thermometer of side amount body temperature.

As everyone knows, the diagnosis human body whether specific purpose tool of cat fever is to be referred to as " mercury (mercury column) clinical thermometer ", this clinical thermometer uses easily, as long as people one do not feel like oneself, with its side amount state of an illness, so that suit the remedy to the case, although the advantage that this mercury clinical thermometer has is with low cost, degree of accuracy is high; But when having the adult of obstacle to have a fever for infant, the patient who can't take care of oneself and linguistic function, the paramedic can not in time find, only (even the time is longer) could take temperature with its side after fever, affects the state of an illness easily adversely, causes adverse consequences.

The purpose of this utility model provides a kind of portable electronic thermometer that can show body temperature at any time and can have a fever and report to the police.

The purpose of this utility model is achieved in that it includes a dial plate shape housing, it is characterized in that in housing, being provided with the integrated temperature sensor that an end is exposed at hull outside, the output terminal of this temperature sensor links to each other with comparator circuit, the output terminal of comparator circuit links to each other with temperature divertor with alarm respectively, temperature divertor is connected with LCD by led driver again, LCD is arranged on the front of dial plate, also is provided with an alarm silence switch in the front of dial plate.The end of above-mentioned integrated temperature sensor is the outside that is exposed at dial plate shape back side of shell.This structure can resemble the band wrist-watch in the time spent mode band the infant or the patient's that can't take care of oneself arm place or on one's body, LCD demonstrates at any time by integrated temperature sensor and passes the body temperature of coming; When the body temperature one of human body surpassed set alarm temperature, alarm can be reported to the police automatically, in time treats with reminds people.

The utlity model has safety rational in infrastructure, easy to use, be specially adapted to the infant.Because the neonate is not sociable, lack resistibility again, because having discomfort to cry and scream does not slightly stop, and be father and mother think usually child be hungry, thirsty or be stranded, by the time find that child has a fever, body temperature has reached about 39 ℃, and many infants suffer from an inflammation of the lungs and fail in time to find that child has a fever and causes.During use, but for the long-term band next to the shin of this thermometer of infant at waist; For linguistic function the adult or the elderly of obstacle are arranged, this thermometer can be lain in the oxter.

The utility model is described in further detail below in conjunction with accompanying drawing:

Fig. 1 is a structure diagram of the present utility model

Fig. 2 is a circuit block diagram of the present utility model

Fig. 3 is a circuit diagram of the present utility model

Shown in Fig. 1-3, among the figure 1 is that dial plate shape housing, 2 is eyelet, in the housing 1 of dial plate shape, be provided with the AN539 integrated temperature sensor that an end is exposed at the back side of shell outside (and contact with skin), the output terminal of this temperature sensor AN539 be arranged in the housing, link to each other by resistance R 1, R2, R3, R4 and the voltage comparator circuit that the T515 comparer is formed, the output terminal of this voltage comparator circuit links to each other with temperature divertor A/D with alarm Y respectively, and temperature divertor A/D is connected by the LED LCD that has driver again.LCD LED is arranged on the front of dial plate, also is provided with an alarm silence switch K in the front of dial plate shape housing 1.But this structure needs the waist of long-term band the infant at time spent root root, and LCD LED demonstrates by integrated temperature sensor AN539, comparator circuit at any time, reaches the body temperature that temperature divertor A/D biography is come; When body temperature one surpasses 37 ℃ of set alarm temperatures, the Rc in the sensors A N539 and the b point voltage of T515 comparer raise, and reached the operating voltage of alarm Y, this alarm Y can report to the police automatically, has had a fever and should in time treat with the reminds people infant.

Claims

1, a kind of electronic thermometer that shows body temperature and have the warning device of having a fever, it includes a dial plate shape housing, it is characterized in that in housing, being provided with the integrated temperature sensor that an end is exposed at hull outside, the output terminal of this temperature sensor links to each other with comparator circuit, the output terminal of comparator circuit links to each other with temperature divertor with alarm respectively, temperature divertor is connected with LCD by led driver again, LCD is arranged on the front of dial plate, also is provided with an alarm silence switch in the front of dial plate.

2, electronic thermometer according to claim 1 is characterized in that the end of integrated temperature sensor is exposed at the outside of dial plate shape back side of shell.
