Embodiment 1

[0010] Referring to Fig. 1, the tube body 3 is a glass tube body, which is made of a circular or triangular or oval glass tube. The length of the pipe is 260-270 mm, and one end of the capillary 6 is closed. Capillary 6 adopts the method of pouring mercury to measure the aperture of its capillary. Melt the pipe body 3 on one side to form a figure-eight channel, that is, the heat storage bubble 4. Before expanding the heat storage bubble 4, preheat the marked part to avoid bursting, and put the white back of the pipe body 3 downward, and melt the mark to form Narrow, the two large and small channels are symmetrical on both sides, and the distance between the expansion mouth and the top of the 8-shaped channel is 5±0.5 mm, and a temperature storage bubble 4 with a length of 5 to 8 mm is formed when it expands. the stress is diffused. The unevenness of the kerf should not exceed 0.5 mm, and the distance from the temperature storage bubble 4 is 8-11 mm. The qualified pipe mater...

Embodiment 2

[0012] Referring to Fig. 2, it is the same as Embodiment 1, except that the pipe body 3 adopts an ABS plastic pipe body, which is set outside the glass inner core pipe 16, and the two ends of the pipe body 3 are provided with a temperature-sensitive bulb connection groove 15, a connecting Slot 17. The temperature storage bubble 4 has a length of 7 to 8 mm and a width of 1.2 to 1.3 mm. The capillary 6 and the temperature storage bubble 4 are arranged in the glass inner core tube 16, and the plastic tube body 3 and the glass inner core tube 16 are made of silicone rubber. Bonding and fixing, the front part of the glued part is at a distance of 5 mm from the temperature storage bubble 4, the bonding length is 3 mm, and the tail is at a distance of 2 mm from the tail of the inner core tube 16, and the bonding is completed with ultraviolet light for one minute Adhesive fixation. The connecting groove 17 and the connecting piece 7 are bonded with trichloroethane glue, and the tempe...

Abstract

The present invention relates to a disposable clinical thermometer and the manufacture method. The temperature is measured and the measured temperature is stabilized by a liquid drainage method, a temperature sensing bulb is a cavity body, colored simethicone temperature sensing liquid and a sodium chloride chip are arranged in the temperature sensing bulb, colorless transparent glycerin assistant fluid or glycerin assistant fluid with obvious color difference with the colored temperature sensing liquid is filled in a capillary pipe, when the temperature is measured, temperature sensing liquid is heated and caused to expand, emitted upwards, raised along the capillary pipe, and the assistant fluid is emitted to the valve body of a temperature locating device. After the temperature is measured, a piston is pressed down, the assistant fluid is emitted to an assistant fluid storehouse through a fluid emission slot, the piston is pressed down and the fluid emission slot is closed, the piston is locked, and simultaneously the chip sodium chloride generates gas in the vacuum state to fill up the space caused by the rise and location of the temperature sensing liquid. The present invention has the advantages that the nontoxic temperature sensing liquid replaces mercury, thus solving the problem of mercury pollution. The measured body temperature is not changed under the influence of the outside temperature, and the disposable operation does not cause cross infection.

Description

technical field [0001] The invention relates to a thermometer for measuring body temperature, in particular to a disposable thermometer and a manufacturing method. technical background [0002] Thermometers for measuring body temperature are generally divided into two types: external measurement and internal measurement. There are ear type, underarm and non-contact type for external measurement, but these thermometers generally have complicated structures and are expensive. In vivo measurement At present, oral or children's anal thermometers are commonly used. This kind of thermometer generally uses mercury as the temperature-sensing material. Mercury will evaporate at high temperature, and it will cause serious pollution to the environment when it is produced, used or disposed of. In particular, repeated use of thermometers used in the body is likely to cause cross-infection of germs or bacteria, and if disinfection is not strict, it will also become a way for disease tran...
