The spray may be used eg. as a nasal spray. It has the medication stored in a sealed reservoir which is punctured by a hollow needle when the pump action is operated. This has finger-grips to operate using the thumb and first two fingers. The first pump action is limited by internal stops. The second pump action follows a simple twist of the applicator and a pump action to the bottom of the pump travel. The spray delivers two equal doses in two separate pump actions eg. a precise nasal spray for migraine. |
