Mercury thermometer standardization groove

Abstract

The invention discloses a mercury thermometer standardization groove, which comprises a test tube frame with a hemisphere-shaped appearance. The hemispherical surface of the test tube frame is provided with multiple slots; the slots are internally provided with radial tube holes; the top part of the slots is provided with a standard hole; temperature measuring ends of the tube holes are concentrated in a local small spherical area; and the bottom part of the tube holes is provided with a base. By adopting the hemisphere-shaped design, to-be-standardized thermometers are inserted in the inner radial tube holes, the bottom parts of the tube holes are concentrated towards the center position of the hemisphere, the temperature measuring ends of all thermometers are ensured to be concentrated in a small area, the problem of different temperature at a different position of a water bath box is avoided, the temperature measurement is more accurate, and errors can be eliminated easily.

Description

technical field [0001] The invention belongs to the technical field of medical appliances, and in particular relates to a mercury thermometer standardization tank. Background technique [0002] Infectious diseases are very harmful to human beings. In the global influenza pandemic of 1918-1919, the global death toll was more than 20 million, and the case fatality rate was more than 2%. There came a great panic. Various examples illustrate the hazards of infectious diseases, and also prove the importance of developing effective vaccines against infectious diseases. Vaccines are a powerful weapon to prevent the spread of infectious diseases. The successful development and marketing of various vaccines have formed an effective immune barrier among the population, greatly reducing the incidence of infectious diseases and significantly reducing the deaths caused by infectious diseases, which contributes to the development of society made an important contribution. [0003] The ...

However, since there is no dedicated slot for standardization of mercury thermometers on the market, each test site will first place a bundle of 3-5 thermometers to be standardized in each hole of an ordinary test tube rack, and then put the whole into a constant temperature thermometer. In the water bath box, after 5-10 minutes, take out the thermometer reading, and select a "qualified" thermometer within a certain error range from the set temperature of the water bath box (or the temperature of a standard thermometer placed in the water bath beforehand) for clinical trials , which will cause a large error

[0004] Chinese Patent Publication No. CN 206792393 U discloses an automatic electronic thermometer detection and calibration device, including an electronic thermometer and an evaporating dish, the evaporating dish is provided with a solution, and the electronic thermometer is arranged in the solution of the evaporating dish. The solution is provided with a temperature sensor, the evaporating dish is set on the temperature control device, and the electronic thermometer and the temperature sensor are connected to the test host, which has the characteristics of high calibration accuracy and fast calibration speed; but the evaporating dish of the device is not Do not fix each thermometer, which will easily cause the thermometer to shake, or even break, and pollute the work area
