Embodiment Construction

[0014] Such as figure 1 and figure 2 As shown, the axillary mercury thermometer of the present invention is composed of a vacuole 100 and a mark 200 connected to the vacuole 100 .

[0015] Wherein, the benchmark rod 200 has a temperature scale on its surface, and a thin pipe 201 communicating with the liquid bubble 100 inside, and the thin pipe 201 has a constriction 202 at a position close to the liquid bubble 100 . In the present invention, the post 200 is bent into a circular ring with a gap between the bubble 100 and the free end 203 of the post 200 . In order to adapt to people of different age groups and arms of different thicknesses, the diameter of the ring can be designed into different specifications in the range of 3-15cm. At the same time, in order to be able to snap the ring into the arm, the width of the gap is designed to be 3 / of the diameter of the ring 4.

[0016] In order to further improve the adhesion of the circular ring on the arm, the central part o...

Abstract

The invention discloses a mercury thermometer for armpit use. The mercury thermometer for the armpit use is composed of a mercury bubble and an index bar which is connected with the mercury bubble, wherein a temperature scale is arranged on the surface of the index bar, a thin pipeline which is communicated with the mercury bubble is arranged in the index bar, a necking is formed at the position, close to the mercury bubble, of the thin pipeline, and the index bar is bent into a ring with a notch formed between the mercury bubble and the free end of the index bar, and diameter of the ring is 3-15cm, and the width of the notch is three fourths of the diameter of the ring. According to the mercury thermometer for the armpit use, due to the fact that the mercury thermometer is provided with the ring structure which can be clamped on the arm of a human body, the trouble that the mercury thermometer needs to be held with a hand when the mercury thermometer is used for measuring axillary temperature is avoided, and therefore the mercury thermometer is more convenient to use.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and relates to an underarm mercury thermometer. Background technique [0002] A thermometer is a tool commonly used by people to measure body temperature. Mercury thermometer is a widely used thermometer. Its structure includes vacuoles and benchmarks. There are scales on the surface of the benchmarks and thin pipes connected to the vacuoles inside. There is a constriction between the thin pipes and the vacuoles. The working principle is: when the mercury in the vacuole is affected by the body temperature, there will be a slight change, and the expansion of the volume of the mercury will cause a significant change in the length of the mercury column in the tube, which can be measured by reading the scale at the top of the mercury column. body temperature. The parts of the human body that the thermometer measures include the mouth, armpits, ear holes, etc. However, when the current t...
