Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical appliances, in particular to a medical experiment gas mixer. BACKGROUND

[0002] Mixed gas refers to a mixture of several gases, which is commonly used in engineering. Mixed gas is usually treated as an ideal gas. Dalton's law of partial pressure states that the total pressure p of mixed gas is equal to the sum of the partial pressures of each component gas. The partial pressure of each component gas is the pressure that the component gas would have if it alone occupied the total volume of the mixed gas at the temperature of the mixed gas.

[0003] Existing laboratory gas mixers are mostly large in size, inconvenient to use and operate, low in mixing efficiency, and poor in practicality. Moreover, the proportion of mixed gas is generally required to be relatively high, and the gas cylinder for storing gas is also required to be relatively high. During storage and use, if the gas cylinder is subjected to strong vibration, impact, or is close to a fire source, exposed to sunlight, drenched in rain, immersed in water, stored for too long, or subjected to changes in temperature and humidity, it may leak, affecting the safety of the user.
