摘要:
A dose counter is provided for coupling with a metered dose inhaler. The dose counter includes a top cover that has a top forming an observation window. The top cover forms an interior space receiving therein a circuit board and an electrical cell supplying electrical power. The circuit board includes a counting circuit and a display screen that is arranged under the window. As such, in the use of the inhaler, depression of the top cover actuates the inhaler and causes the display screen to display the number of times of actuation so as to allow a user to realize the remaining number of times for use of the inhaler thereby improving safety of medication use.
