摘要:
The invention relates to an administration device for administering a fluid product, which comprises: a housing (7) having a reservoir (6) for the product, an expulsion device (8), which acts on the product contained in the reservoir (6) to dispense said product, a propulsion device (11) that acts on the expulsion device (8), a movable actuation device (3) which is coupled to the propulsion device (11), two different initial positions (32; 33), starting from which the actuation device (3) is set moving to dispense the fluid product, and a restoring device (10) that restores the actuation device (3) after movement from the one initial position (32; 33) to the other initial position (33; 32). The administration device is configured in such a manner that the movement of the actuation device (3) from the different initial positions (32; 33) is associated with different quantities of dispensed fluid.
摘要:
A medication dispensing apparatus having a manually operable plunger axially shiftable relative to the apparatus housing. The plunger is pullable relative to the housing in a proximal direction to cock the apparatus, and when the plunger is then manually pushed back toward the housing, a piston within a medicine container of the apparatus is shifted to force medication from a needle assembly at the distal end of the apparatus. The medication dispensing apparatus also includes a priming mechanism which is operated by rotating an externally accessible driver portion to prime the apparatus for use, which priming can be performed whether or not the apparatus is in a cocked state.

The invention relates to an administration device for administering a selectable dose of a fluid product, said device comprising: a) a housing (1, 3) with a first housing section (1) that accommodates a reservoir (2) for the product and a second housing section (3), b) an expulsion device (K, 8), which acts on the product in the reservoir (2) to dispense said product, c) a dosage member (13/14), which forms a dosage stop (15) and is displaceably coupled to the housing (1, 3) for adjusting the dosage stop (15) that enables the product dose to be selected and d) a propulsion device (10/18) that acts on the expulsion device (K, 8). The propulsion device is housed by the second housing section (3), carries out a dispensing stroke (Ah) in a direction of propulsion that drives the expulsion device (K, 8), until said propulsion device reaches a dispensing stop (5), and can be displaced against the direction of propulsion until it reaches the dosage stop (15). According to the invention, in order to adjust the dosage stop (15), the dosage member (13/14) can be displaced in a translatory manner in and/or against the direction of propulsion and the dosage member (13/14) and the second housing section (3) are coupled by means of an articulation (6, 16), in such a way that a rotational displacement of the dosage member (13/14) in relation to the housing (1, 3), causes the translatory displacement of said dosage member (13/14).
摘要:
Disclosed is a device for administering a fluid product, comprising a unit for the contactless measurement of a position between elements (1, 3) of the apparatus, which are movable relative to each other. Said measuring unit encompasses at least one magnetoresistive sensor (2; 6) that is fixed to a first element (1) and is disposed opposite at least one second element (3) which is movable relative to said first element (1). A magnetic unit cooperates with the at least one sensor (2; 6). Said magnetic unit is optionally or simultaneously embodied at least by a permanent magnet (11) on the first element (1) and at least a magnetizable second element (3) that has a predetermined surface profile (14). Alternatively, the magnetic unit is provided with at least one permanent magnet (12) comprising several alternately arranged different magnet pole areas (N, S) on at least one second element (3).

An embodiment of the present invention provides an apparatus for setting a dose of a drug in a syringe having a plunger, comprising an outer housing (202) and an inner housing (200) adapted for encircling the syringe (10), such that the inner housing (200) is positioned within the outer housing (202) to set the dose of the drug. In an embodiment, the apparatus further comprises a dosage indicator (1012) disposed on the inner housing (200) and the outer housing (202) further comprises an opening for viewing the dosage indicator (1012).
摘要:
An injection device for injection of set doses of medicine from a cartridge, in which syringe a dose is set by screwing a nut up along a threaded piston rod, whereby a dose setting drum, which carries on its cylindrical surface along a helix a scale of which a number corresponding to the set dose is shown in a window in the housing of the syringe, and an injection button, which is elevated over the end of the syringe, are moved axially a distance which is larger than the axial movement of the nut. A gear wheel gear transmission is established between the nut and the injection button.
摘要:
A limiting mechanism which prevents the setting of a dose, which exceeds the amount of liquid left in a cartridge of an injection device is disclosed. The injection device is the type where a dose is set by rotating a dose setting member relative to a driver and away from a fixed stop in the injection device. The dose setting member interfaces the driver such that the dose setting member can be rotated in one direction without rotating the driver. The dose is injected by rotating back the dose setting member which during the backward rotation carries the driver with it. Rotating the driver causes the piston rod to move forward inside the cartridge and expel some of the liquid contained in the cartridge. The driver is provided with a track having a length which is related to the total amount of liquid in the cartridge and which track is engaged by a track follower coupled to the dose setting member to follow rotation of this dose setting member. Each time a dose is set and injected, the track follower moves further into the track. When the track follower reaches the end of the track the dose setting member cannot be rotated further, and a dose larger than the remaining liquid in the cartridge cannot be set.

This invention concerns a propelling device for a piston in a container containing liquid medicament. The propelling device consists of a base element (1) and a first sliding stage (10) which can slide with respect to the base element (1) and, when slid, presses against the piston advancing said piston in the container, as a result of which a dose of medicament fluid is forced from the container. At least one second sliding stage (20) is provided which also can slide in the direction in which the piston advances with respect to both the base element (1) and the first sliding stage (10) and carries the first sliding stage (10) along when slid in the direction in which the piston advances when seen in the direction in which the piston advances, the first and second sliding stages (10, 20) overlap at least in part.

The invention relates to a device for administering a dose, comprising a housing with a reservoir, a piston that pushes out the product from the reservoir when its is displaced towards an outlet of said reservoir in the advance direction, a drive member (6), a driven member that is entrained by the drive member (6) when said drive member (6) is displaced in the advance direction and that pushes the piston in the advance direction and a dosing member (15) that can be rotated around the displacement axis (V) of the drive member (6) to regulate the administration of a dose of the product to be delivered. The drive member (6) and the dosing member (15) come to rest with at least one stop (14, 18), one of which is embodied on the drive member (6) and the other one is configured on the dosing member (15). At least one of said stops (14, 18) runs at least spirally around the displacement axis (V) of the drive member (6). The at least one spiral stop (18) has a progression with a constant slope (α).
