A multifunctional spray can

Abstract

The invention relates to a multi-functional spray can, and belongs to the technical field of medical instruments. The multi-functional spray can comprises a can body with a liquid storing cavity, a buffering cover arranged in the liquid storing cavity and a can cover installed on the can body, wherein a high-pressure nozzle is arranged at the bottom of the liquid storing cavity of the can body, a medicine liquid channel is formed in the center of the can cover, and an air outlet hole cavity and a medicine adding hole cavity are formed in the top of the can cover. The multi-functional spray can has the advantages that an aerosol amount adjusting mechanism comprises an adjusting cover and an adjusting valve, the adjusting cover is arranged in the medicine adding hole cavity, an adjusting rod through hole is formed in the middle of the bottom of the adjusting cover, a ventilating window is arranged between the periphery outside the adjusting rod through hole and the wall body of the adjusting cover, and a flange is formed on the upper edge of the adjusting cover and matched with the outer edge of the medicine adding hole cavity in a sealed mode; the adjusting valve is located below the adjusting cover, the axial middle of one side, facing toward the adjusting cover, of the adjusting valve is provided with an adjusting rod in an extending mode, a limiting flange is arranged on the lower middle portion of the adjusting rod in the height direction, and the upper end of the adjusting rod penetrates through the adjusting rod through hole and then extends upwards out of the adjusting cover. The multi-functional spray can has the advantages of being capable of automatically adjusting the aerosol amount conveniently in a wide adjusting range and avoiding waste of medicament.

Description

technical field [0001] The invention belongs to the technical field of medical devices, and in particular relates to a multifunctional spray tank. Background technique [0002] Nowadays, with the air pollution becoming more and more serious, coupled with the sudden cold and warm weather during the transition of seasons, the number of patients with respiratory diseases has increased significantly. The traditional oral medicine treatment mode can no longer meet various complex treatment conditions and modern people's high-quality demand for life. Nebulization inhalation treatment has become an important and effective means in the treatment of respiratory diseases. Nebulization inhalation treatment uses a nebulizer inhaler to atomize the liquid medicine into tiny particles, and the medicine enters the respiratory tract and lungs for deposition through inhalation, so as to achieve the purpose of painless, rapid and effective treatment. At present, the most commonly used is the ...

AI Technical Summary

Problems solved by technology

Spray cans can be used with different air pressure sources. When the air pressure source is constant, the atomized particles and atomization rate are constant. Medical staff cannot adjust the appropriate atomization rate or atomized particles according to different groups of people and conditions, which reduces the Treatment effect, but also caused a waste of drugs and materials

Chinese Utility Model Patent Authorization Announcement No. CN202777335U introduces a "pharmaceutical spray tank", which uses an adjustable air valve to adjust the flow rate of natural air inhaled into the pharmaceutical spray tank to control the atomization speed of the pharmaceutical spray. At least one port is opened on the side wall, and the number and size of different ports can be set to be applicable to different dosage situations. The specific dosing conditions of patients of all ages, such as breathing rhythm, etc. to control the atomization speed

In addition, since the air outlet of the spray tank is directly connected to the internal liquid storage chamber, when the patient accidentally tilts the spray tank during the medication, the liquid medicine will overflow from the air outlet, resulting in waste
