Medical vaporizer

Abstract

The invention discloses a medical vaporizer comprising a cup body, a jet retaining part and a cover cap, wherein the bottom of the cup body is fixedly connected with an air connecting tube in a perforated way; the end, extending into the cup body, of the air connecting tube, is provided with a circular cone head in which an air outlet is formed, and the other end of the air connecting tube extends out of the bottom of the cup body to be used for introducing external compressed gas; the jet retaining part comprises a mushroom head annularly sleeving the circular cone head and a jet baffle fixedly arranged on the top of the mushroom head, a first spray outlet communicated with the air outlet is formed in the middle of the mushroom head, and the jet baffle is dead against the spray outlet; the cover cap covers the opening edge of the cup body, a negative-pressure hole and a second spray outlet are formed in the cover cap, one end of the negative-pressure hole annularly sleeves outside the jet baffle and supports against the mushroom head, and the other end of the negative-pressure hole is communicated with the outside; one end of the second spray outlet is communicated with the inside of the cup body in a sealing way, and the other end of the second spray outlet is abutted with an external nipple. The medical vaporizer can provide relatively small atomized particles on the basis of ensuring high atomization quantity and avoid side leakage.

Description

technical field [0001] The invention relates to an atomizing device, in particular to a medical atomizer. Background technique [0002] Atomized inhalation therapy is a commonly used therapy for respiratory diseases. It needs to use a nebulizer / nebulizer to atomize the drug into atomized particles and directly act on the lesion, so as to achieve the effect of small dosage, quick effect and few side effects. advantage. [0003] At present, when the nebulizer is used clinically, it needs to be combined with a drug catheter to input the drug, and a mouthpiece is used for the patient to receive the treatment. But, there is following defective in existing sprayer: [0004] (1) The amount of atomization is small; [0005] (2) The atomized particles are relatively large, easy to gather and produce water droplets, and it is difficult to fully diffuse to the lesion; [0006] (3) Side leakage is easy to occur during use, and it cannot be inverted, which is inconvenient to use; ...

AI Technical Summary

Problems solved by technology

[0005] (2) The atomized particles are relatively large, easy to gather and produce water droplets, and it is difficult to fully diffuse to the lesion;

[0006] (3) Side leakage is easy to occur during use, and it cannot be inverted, which is inconvenient to use;

[0007] (4) The saliva produced by the patient's mouth will enter the nebulizer after the mouth, causing pollution to the medicine, or the saliva adheres to the outer wall of the nebulizer, making it difficult to achieve hygienic use
