Abstract

The invention provides an aerosol valve counting indicator. The indicator mainly comprises a push button, an actuating rod, a worm, a counting disc and an outer cover, wherein a sliding groove is formed in one outer side face of the push button; the actuating rod is clamped in the sliding chute, wherein the structure of the actuating rod is matched with that of the sliding chute; a cantilever protruding outwards is arranged on one side of the actuating rod; the cantilever extends into the push button; an actuating claw protruding outwards is arranged on the other side of the actuating rod; a worm is arranged on the outer side of the actuating rod; a coaxial ratchet wheel is arranged at one end of the worm; the position of the ratchet wheel is matched with that of the actuating claw; the actuating claw is clamped between the ratchet wheels; the two ends of the worm are clamped into supporting seats, the supporting seats are fixed to the outer side wall of the push button, a sleeve is arranged at the position, above the sliding groove, of the outer side wall of the push button, the sleeve is sleeved with a counting disc, the counting disc is correspondingly arranged above the worm, counting teeth of the counting disc are meshed with the worm, and the outer cover is arranged on the outer side of the counting disc.

Description

technical field [0001] The invention relates to the field of medical products, in particular to an aerosol valve counting indicator. Background technique [0002] Aerosol is a commonly used medical device, which can use the pressure of the propellant to spray the liquid in the container into a mist for the treatment of patients. At present, the structure and function of the push button of the aerosol dispenser on the market are relatively simple, and there is no counting function, so the user cannot know the number of times the device is used. The user cannot know the number of times the device has been used, the total number of times the device has been used and the remaining number of times it has been used. It is easy for the device to be discarded after it is still usable, or the device has been emptied but still used. Contents of the invention [0003] In order to solve the above problems, the present invention proposes an aerosol valve counting indicator, which can ...
