Description

The utility model relates to a pacifier for measuring the body temperature of infants and young children, which belongs to the category of medical instruments.

At present, the thermometers used to measure the body temperature of infants and young children generally use a thermometer with mercury in the glass core, which is inserted into the anus of the baby or clamped under the armpit to measure the body temperature. inconvenient.

The purpose of the utility model is to provide an electronic thermometer with display and alarm functions, which allows babies to suck and bite to measure body temperature through a pacifier.

The principle of the utility model is to make a pacifier with a dense and soft material. The pacifier head is hollow, and the inside of the pacifier is filled with a liquid that is easy to conduct heat. The thermistor in contact with the liquid sends a signal of temperature change to a The integrated circuit is amplified and processed, and the baby's body temperature is displayed through the liquid crystal. When the body temperature exceeds the normal body temperature, the buzzer will sound an alarm.

There are several glue holes 22 sunken inwards. The outer diameter of the housing 2 is the same as the inner diameter of the base 1. The two are fixed together with waterproof glue. The base 1 and the nipple 11 are made of firm and soft materials. Be formed and connected as a whole, the nipple 11 is hollow, the outer diameter of the cylindrical protective tube 14 can be plugged into the circular hole 21, and glued and fixed in the circular hole 21 with waterproof glue, the circle on the left side of the protective tube 14 A thermistor 15 is placed in the tube, the right end face of the protective tube 14 is on the same plane as the cylindrical peripheral edge 23, and is sealed on the plane with a rubber sheet 3, so that the teat 11, the base 1, the main shell 2 And protective tube 14, rubber sheet 3 form a sealed space, be filled with the liquid 12 that is easy to conduct temperature in this space, such as distilled water or other liquids that are easy to conduct heat, liquid crystal display and integrated circuit board 6 are connected together with conductive rubber 10 And be placed in the main housing 2, the buzzer 7 is fixed on the integrated circuit board 6, the decorative sheet 5 is a circular sheet with a grid shape or other air holes, and a rectangular window is opened above it, which can make the liquid crystal display 4 stretches out from this window, has groove 18 on the handle 9, and battery 16 is placed in the groove.

Accompanying drawing 3 is the cross-sectional view of accompanying drawing 1, the heat-conducting liquid 12 that fills in the teat 11, along with the baby, young child bites and sucks the teat 11, flows continuously inside it, and contacts with the thermistor 15, turns the heat-conducting liquid The temperature change is transmitted to the integrated circuit IC on the integrated circuit board 6 for processing, or displayed on the liquid crystal display 4 or sounded by the buzzer 7 .

Accompanying drawing 3 integrated circuit diagram, among the figure integrated circuit IC input terminal has thermistor 15, resistance R ₁ , adjustable resistance R ₃ , electric capacity C ₁ , adjust the value of resistance R ₃ , can make buzzer 7 when human body temperature exceeds normal beeps when value is reached.

The utility model has the advantages of utilizing the habits of infants and young children biting and sucking nipples, and adopting electronic temperature measurement technology, which is absolutely safe and reliable for infants and young children, and is convenient for measurement. It can automatically display body temperature or warn infants and young children that their body temperature exceeds normal body temperature.
