An adapter or spacer 5 allows a generic inhaler usage counter 1 to be assembled on to different inhaler housings 2 by changing the spacer interface and may be used on any type of canister 4 that dispenses through a nozzle when placed inside a housing in order to count the number of displacements between the canister and housing. It may provide an extra security measure on the reliability of the counter when used in-conjunction of other techniques of counting the remaining drug inside the canister. A battery, switch, and PCB sealed within the dose counter unit electronically count drug doses and a motion sensor detects movement of the inhaler and displays the amount of remaining drug uses. |
