Embodiment Construction

[0024] Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0025] The liquid ejection cartridge of the present invention is characterized in that it includes a plurality of liquid storage portions separated by thin films, and a penetrating member for penetrating the thin films so that the liquids respectively stored in the respective liquid storage portions can be mixed. As long as at least one of the plurality of liquid storage parts communicates with the liquid ejection part, the mixed liquid (liquid mixture) can be supplied to the liquid ejection part. According to the structure of the present invention, it is possible to mix different kinds of liquids with a simple structure.

[0026] That is, the liquid ejection cartridge of the present invention includes a liquid ejection portion for ejecting liquid, a first liquid storage portion separated from the liquid ejection portion by a thin film, and a s...

Abstract

Provided are a liquid ejection cartridge and a liquid ejection device each having a simple structure capable of surely mixing a plurality of liquids. The liquid ejection cartridge according to the present invention includes a liquid ejection portion (12) for ejecting a liquid; a first liquid storage portion (3) which is separated from the liquid ejection portion (12) through a film (10); a second liquid storage portion (4) which is separated from the first liquid storage portion (3) through a film (9). Further, the liquid ejection cartridge further includes a first penetrating member (8) for penetrating the film (10) which separates the liquid ejection portion (12) and the first liquid storage portion (3); and a second penetrating member (7) for penetrating the film (9) which separates the first liquid storage portion (3) and the second liquid storage portion (4).

Description

technical field [0001] The present invention relates to a liquid ejection cartridge and a liquid ejection device. The liquid ejection cartridge and the liquid ejection device according to the present invention are suitable for use in inhalation devices and the like used when aerosolizing liquid medicine and allowing the medicine to be inhaled into the body (particularly lungs) in the field of medicine. Background technique [0002] In recent years, average life expectancy has been increasing due to advances in medicine and science thereby increasing the aging population. However, eating habits or living environments have changed, environmental pollution has also increased, and new diseases and infections have emerged due to viruses or bacteria, thereby aggravating people's health concerns. In particular, in so-called developed countries, there is a problem that the number of patients with lifestyle-related diseases such as diabetes and hypertension increases. [0003] On t...
