Embodiment Construction

[0041] The fluid discharge device shown in FIGS. 1 and 2 comprises: a housing 1 comprising an applicator portion 1 a , an upper body portion 1 b , a lower body portion 1 c and a base 1 d ; an actuator 2 ; and a liquid discharge assembly 3 .

[0042] The liquid discharge assembly 3 includes a liquid discharge unit 4 , a carrying unit 5 and a connection unit 6 , wherein the carrying unit 5 carries the liquid discharge unit 4 , and the connection unit 6 connects the movement of the actuator 2 and the carrying unit 5 .

[0043] The actuator 2 is in the form of a cover member and is movable relative to the housing 1 (1a, 1b, 1c, 1d) between a first position and a second position, actuating the fluid discharge device. Although the actuating member 2 is shown as a cover pivoted on the connecting member 6, other forms of actuating member may be used, provided that in the second position, the actuating member moves the carrying unit 5 as desired.

[0044] The fluid ejection device also...

Abstract

The invention relates to a manually actuated fluid discharge device for delivering doses of liquid, the fluid discharge device comprising a housing (1) comprising an outlet through which used liquid is delivered. The actuating part (2) is movable relative to the housing (1) between a first position and a second position, into which the user moves the actuating part (2) to actuate the fluid discharge device. A liquid discharge assembly (3) is at least partially located in the housing (1), the liquid discharge assembly (3) comprising a liquid discharge unit (4), a carrying unit (5) for carrying the liquid discharge unit (4) and a connecting part (6), the connecting part connects the movement of the actuating part (2) and the bearing unit (5). Movement of the carrying unit (5) drives a counting mechanism (7a, 7b) indicating the dose of medicine delivered.

Description

technical field [0001] The present invention relates to a manually actuated fluid discharge device for delivering volumes of liquids, especially liquids containing medicaments. Background technique [0002] An example of such a fluid removal device is disclosed in WO 92 / 20455 in the form of a nasal inhaler for delivering a quantity of a medicament-containing liquid as a spray into the nasal cavity. The fluid ejection device includes a nozzle as part of the applicator for insertion into the nasal cavity. The applicator portion delivers a spray and is configured to be manually actuated by applying a force axially relative to the longitudinal axis of the nozzle. [0003] While such devices are capable of delivering a measured volume of liquid, fluids used to deliver nasal sprays tend to cause the applicator portion to move axially within the nasal cavity, which can result in ineffective delivery of the liquid. The use of the discharge device can be complex. Contents of the ...
