摘要： This medicine ejection device is directed at uniformizing an amount of a medicine inhaled by a user through a mouthpiece: and ejects a predetermined constant amount of the medicine by measuring a remaining amount of the medicine in a reservoir 7 at every inhalation time with the use of a strain gauge 37, which supplies the medicine through a connection tube 8b to an ejection head 8a for ejecting a medicine into a flow path 20 of a mouthpiece 4, so as to compensate for a decrease of an amount to be inhaled due to the deposition of the medicine in a nozzle (orifice) of the ejection head 8a, and by adjusting an ejecting operation duration of the ejection head 8a when the user inhales the medicine next time.

摘要： A liquid cartridge of the present invention has a liquid ejection portion 1 for ejecting liquid droplets, a reservoir E1 for storing liquid, and a communicating member 3 for providing communication between both of them. The reservoir E1 has first and second storage portions 10a, 10b isolated by films 6 to 8 arranged spaced from each other and an atmospheric release portion. When a small diameter portion 5a is inserted into an applied concave portion 4 of the liquid ejection portion 1, a tip 3a of the communicating member 3 breaks through the first to third films 6 to 8 sequentially in the period from the beginning to the end of insertion. Consequently, liquid in the first storage portion 10a is filled into the ejection head 2 and thereafter liquid stored in the second storage portion 10b is filled.
