Thus, the dosage can be accurately controlled even if the intermediate stop is made.

Description

Anesthetic quantitative sprayer

Technical Field

The invention relates to the technical field of medical instruments, in particular to an anesthetic quantitative sprayer.

Background

The increasing number of patients today makes the use of devices related to assisted medical treatment more and more widespread. Some existing pesticide sprayers are relatively simple in structure, but the pesticide spraying amount cannot be accurately controlled. Too much or too little of the drug spray has a greater effect on the overall anesthetic effect. Some quantitative medicine sprayers need to be pressurized once, so that the quantitative medicine can be sprayed out, otherwise, the quantitative medicine sprayers need to be pressurized again, and the efficiency is affected. An anesthetic sprayer like [ CN 201949478U ] has no quantitative function in the spraying process; in the case of a quantitative anesthetic sprayer such as the one [ CN 202314837U ], the pressurization process must be properly performed, otherwise, the pressurization process must be restarted.
