Description

An anesthesiology nebulizer

technical field

The utility model relates to the technical field of medical equipment, in particular to a sprayer for anesthesiology.

Background technique

Nebulizer is the abbreviation of spray equipment. Nebulizer is a device that uses air suction to turn potions or other liquids into mist and spray them evenly on other objects. It consists of compressed air devices, thin tubes, nozzles, etc. There are four principles of spraying, Bernoulli's principle, Bernoulli's principle says that in the same fluid, the flow rate is large, the pressure is small; the flow rate is small, the pressure is strong. Fluid will automatically flow from high pressure to low pressure. When passing through the three-pronged pipe, the water flowing at a low speed flows to the air flowing at a high speed. The water is torn into small droplets by the high-speed air. These small water droplets become mist after being sprayed out. The high-speed water flow hits an obstacle and then breaks into small water droplets. The principle that the high-speed water flow breaks into small water droplets after encountering an obstacle. The situation is like opening the faucet and blocking it with your fingers. The household sprayer mostly uses this structure, the cost is low, and the centrifugal force throws the liquid out. The liquid is thrown out by centrifugal force and shredded into small droplets, which is similar to the situation when the umbrella rotates. The vibration of the ultrasonic atomization principle can cause "waves" on the water surface. The vibration frequency of ultrasonic waves is very high, so the wavelength of its "waves" is very high. Small, so its "spray" small water droplets are also small, and these small water droplets become fog.

At present, nebulizers are widely used in the medical field. Because of the nebulizer, the medicine can be applied more evenly at night, and it is simple and convenient to use. The existing medical nebulizers generally do not have the anti-sucking function, which may cause the medicine to be sucked due to the sucking back. If the karma flows back to the medicine pot, it is easy to contaminate the medicinal liquid in the pot, thus endangering the health of the patient.
