Pressure adjusted type otorhinolaryngologic clinical medicine spraying device

Abstract

The invention discloses a pressure adjusted type otorhinolaryngologic clinical medicine spraying device. The device comprises a shell body, wherein the front end of the shell body is cooperatively provided with a sleeve, the front end of the sleeve is internally fixedly provided with an atomizing nozzle, the rear end of the atomizing nozzle is cooperatively provided with a front end medicine delivery pipe, the outer portion of the front end medicine delivery pipe and the shell body are cooperatively arranged through a bearing pair, the outer portion of the tail end of the front end medicine delivery pipe is fixedly provided with a friction ring, the friction ring is in contact with a friction wheel at the end portion of a motor output shaft, a motor and the shell body are fixedly arranged,the tail end of the front end medicine delivery pipe and a rear end medicine delivery pipe are cooperatively arranged, the lower portion of the shell body is provided with a mounting seat, the mounting seat is internally fixedly provided with an agentia bottle through a thread, and the rear end medicine delivery pipe penetrates through the mounting seat of the shell body; the injection pressure of the pressure adjusted type otorhinolaryngologic clinical medicine spraying device can be adjusted, and the spraying effect is not affected by the spraying angle and the amount of medicine liquids.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a pressure-adjustable clinical medicine spraying device for otolaryngology. Background technique [0002] At present, the storage bottle and the spray tube of the sprayer used in the ENT department of the hospital have an integrated structure, and the sprayer will be heavy when the doctor holds it in his hand. Flexible spraying. In the outpatient treatment of otolaryngology, the spray device is often used as an important device for applying medicine to the deep part of the ear, nose and throat. The atomization of the device is not good, so the effect of treatment is often not ideal. Especially in the actual spraying treatment operation process, it is necessary to constantly change the angle of the sprayer. When the liquid medicine is getting less and less, the medicine suction tube is likely to be unable to reach the medicine liquid, and it is impossible to absorb the m...

[0002] At present, the storage bottle and the spray tube of the sprayer used in the ENT department of the hospital have an integrated structure, and the sprayer will be heavy when the doctor holds it in his hand. flexible spraying

In the outpatient treatment of otolaryngology, the spray device is often used as an important device for applying medicine to the deep part of the ear, nose and throat. The atomization is not good, so the treatment effect is often not ideal

Especially in the actual spraying treatment operation process, it is necessary to constantly change the angle of the sprayer. When the liquid medicine is getting less and less, the medicine suction tube is likely to be unable to reach the medicine liquid, and it is impossible to absorb the medicine liquid into the spray tube. The pressure in the existing sprayer cannot be adjusted, resulting in poor spraying effect
