AI Technical Summary

Problems solved by technology

The defect of the above device is that the drug storage chamber of the nebulizer must be located above the atomizing sheet during the atomization operation to ensure the effect of fog formation, which brings more inconvenience to the operator in actual application.
[0006] A problem common to the above devices or systems is the large number of interfaces, which makes the doctor's preparation work more troublesome, and at the same time, the operation of the nebulizer is inconvenient

Abstract

The invention discloses a nebulizer and a ventilation system. The nebulizer is an ultrasonic nebulizer with a switch; the ultrasonic nebulizer includes a drug storage cavity, a mist outlet and a drugadding port connected with the drug storage cavity; the drug storage cavity is a flexible and deformable drug cavity; the bottom part of the drug storage cavity is provided with an ultrasonic nebulization sheet controlled by a host; the ultrasonic nebulizer is also provided with an air return port, the air return port communicates with the mist outlet, and an air passage making the air return portand the mist outlet communicate is provided with a recovery sponge; the recovery sponge fills at least one section of the air passage; the ventilation system comprises an anesthesia machine, a three-way pipe, and the nebulizer; two of interfaces of the three-way pipe are connected with the air inlet and the air outlet of the anesthesia machine respectively, and the remaining interface of the three-way pipe is connected with the air return port of the nebulizer; and the mist outlet of the nebulizer is connected with a tracheal catheter or face mask or laryngeal mask through a ventilation adaptor. The nebulizer of the invention can be conveniently combined with the anesthesia machine to realize intraoperative nebulization, has few interfaces, is convenient to operate and has less drug loss.

Description

technical field [0001] The invention relates to an atomizing device for drug administration in the respiratory tract. Background technique [0002] At present, due to the precise effect of nebulized drug administration, the advantages of less drug dosage and mild side effects, etc., have been recognized by everyone. Nebulizers are widely used in clinical and daily life. According to their nebulization principles, they are mainly divided into two categories, ultrasonic nebulizers atomizer, compression atomizer. There are many mature commercially available products for the two types of nebulizers. [0003] The Chinese invention patent application "A Nebulizing Inhaler for Anesthesia" published on January 24, 2020 with the publication number CN110721381A discloses a nebulizer used in surgery, which uses a compressive nebulizer, The mist outlet of the nebulizer is connected to the endotracheal tube or mask through the L-shaped joint, and the other end of the L-shaped joint is ...
