Abstract

The present invention proposes an aerosol valve counting indicator, which mainly includes: a push button, an actuating rod, a worm, a counting disk and an outer cover. A chute is opened on an outer surface of the push button, and the actuating rod It is clamped in the chute, the structure of the actuating rod matches the chute, one side of the actuating rod is provided with a cantilever protruding outward, and the cantilever extends into the push button, and the actuating rod An outwardly protruding actuation pawl is provided on the other side of the actuation rod, a worm is provided on the outside of the actuation rod, and a coaxial ratchet is provided at one end of the worm, the position of the ratchet matches the actuation pawl, The actuating pawl is clamped between the ratchets, the two ends of the worm are clamped into the support seat, the support seat is fixed on the outer wall of the push button, and a sleeve is arranged at the outer wall of the push button above the chute , a counting disc is sleeved on the sleeve, the counting disc is correspondingly arranged above the worm, the counting teeth of the counting disc mesh with the worm, and the outer cover is arranged outside 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 spray the liquid in the container into a mist with the help of the pressure of the propellant for the treatment of patients. At present, the push button of the aerosol dispenser on the market is relatively simple in structure and function, and has no counting function, so the user cannot know the number of times the device is used. The user cannot know the usage times of the device, the total usage times and the remaining usage times of the device, and the situation that the device can still be used but is discarded or the device is emptied but still used is likely to occur. SUMMARY OF THE INVENTION [0003] In order to solve the above problem, the present invention proposes an aerosol valve counting indicator, which can solve the problem that the existing aer...
