Embodiment Construction

[0043] The delivery device includes a main body part 1, which in this embodiment has a substantially cylindrical tube cross-section, which includes first and second open ends 3, 5 and first and second end main body parts 7, 9 which are connected to the main body Part 1 is so as to close the open ends 3, 5 and define a closed housing. In this embodiment, the main body part 1 and the first and second end main body parts 7, 9 are made of a plastic material and connected by a plastic welding, for example, it can be realized by ultrasonic welding.

[0044] The main body 1 includes a first side opening 11 at the first end 3, which is substantially square in this embodiment. One side of the first side opening 11 is opened at the first end 3, and its adjacent side is substantially parallel to The longitudinal axis of the main body portion 1 extends. The main body portion 1 further includes first and second lugs 15 and 17 which are arranged on the corresponding side of the longitudinally e...

Abstract

The invention provides a manual delivery device for delivering a volume of liquid, comprising: a housing including an outlet (27) for delivery of the liquid in use; a cover element (39) relative to the housing The body is movably arranged between a first position in which the cover element (39) at least partially covers the outlet (27) and a second position in which the cover element (39) covers the outlet (27) with As a lever, in use, is manipulated by the user to actuate the delivery device. The delivery device also includes an indicator indicating the number of actuations of the delivery device. Means are also provided for locking the delivery device in order to prevent further operation of the delivery device after it has been actuated a predetermined number of times.

Description

Technical field [0001] The invention relates to a manual delivery device for delivering a certain volume of liquid, especially a liquid containing medicine. Background technique [0002] WO-92 / 20455 discloses an example of such a delivery device, which takes the form of a nasal inhaler to deliver a certain volume of liquid containing medicine into the nasal cavity as a mist. The delivery device includes a nozzle with an elongated tube cross-sectional shape for inserting into a nasal cavity to deliver mist through the tip of the nozzle, and the nozzle is configured so that it can be manually applied to the longitudinal axis of the nozzle according to the force applied in the axial direction. Actuate. [0003] Although this delivery device can deliver a certain amount of liquid, it is troublesome to use the delivery device as a nasal inhaler when the manual force applied in the axial direction tends to cause the nozzle to move in the nasal cavity that caus...
