摘要： A setting mechanism for a dosing device, in particular for a device for dosing pharmaceutical or therapeutic substances, the setting mechanism including: a controlling assembly for connecting the setting mechanism with a dose setting element of the dosing device; a driving assembly for connecting the setting mechanism with a driving element of the dosing device; a dosing assembly for connecting the setting mechanism with a dosing element of the dosing device. The controlling assembly is coupled with the dosing assembly by a spring element, which can deform from a coupled position to a decoupled position during rotation of the dose setting element. The spring element is configured to allow a displacement of the controlling assembly with respect to the dosing assembly. In the coupled position the spring element is configured to block a rotation of the controlling assembly with respect to the dosing assembly.

摘要： An automatic applicator for liquid pharmaceutical preparations, particularly for multiple injection application of set doses of a medicine from an exchangeable container is provided. The automatic applicator includes a body housing connected to a housing of an exchangeable container with a medicine having a plunger, the said plunger being displaced only linearly by an integrated driving unit, suitable for immobilizing, driving, leading linearly and blocking rotation of the plunger, driven via a double action clutch, by a tensioning spring situated in the body housing, the spring tensioned by a rotary hand-dose-setting ring via the double action clutch, wherein the driving unit is activated by a trigger unit and a dose is indicated by an indicating arrangement. The automatic applicator further includes at least one block key placed in an upper part of a ratchet barrel, collaborating with at least one key placed in an internal part of the body housing.

摘要： An injection device for delivering equal doses of a fluid contained in a reservoir, the device having a housing, and an arming mechanism and a dose delivery mechanism arranged therein, the housing coupled to an enclosure for the reservoir. The arming mechanism includes an axially non-displaceable and rotatable setting sleeve. The setting sleeve is coupled with a spring strained by the rotation of the setting sleeve during arming of the device. The dose delivery mechanism includes a screw ring and a non-rotatable and axially displaceable piston rod within the setting sleeve. The piston rod cooperates with the screw ring so that during arming, the screw ring and the piston rod are immobilized, and during delivery of each dose the piston rod is displaced along the housing due to unwinding of the spring and rotation of the screw ring, the displacement of the piston rod causing the fluid to be discharged from the reservoir.

摘要： A clutch assembly with a blocking system for a medical injection device, in which a first ratchet sleeve (3) is mounted on the clutch sleeve (2), the first ratchet sleeve (3) being rotatable in two directions and cooperating with a second ratchet sleeve (4) which is mounted on the first ratchet sleeve (3), the second ratchet sleeve (4) being rotatable only in one direction, the housing (1) has an internal toothed ring (1.1), the first ratchet sleeve (3) has at least one ratchet (3.1), and the second ratchet sleeve (4) has an internal toothed ring (4.1) and at least one ratchet (4.2). The second ratchet sleeve (4) and the housing (1) have blocking means (4.3, 1.2) for preventing the arming of the device when an insufficient volume of the medicament remains in the container, by blocking the rotation of the second ratchet sleeve (4) in relation to the housing (1).

摘要： Injecting device with dose resetting mechanism enables release energy accumulated in spring means (17) and causes automatically the back movement of an indicating element (16) to its initial position without causing any axial movement of a threaded piston rod (10), said actions being initiated by one movement of a dose setting element (4) in the direction opposite to that when setting a dose. Reset clutch (13) is made as an axially sliding, shaped coupling element moved by means of the dose setting element (4), and moreover this reset clutch (13) is functionally connected with a drive unit destined to co-operate with the spring means (17) in such a way that when this reset clutch (13) is released, said drive unit is disconnected from the spring means (17) retaining the connection of this spring means (17) with the indicating element (16).

摘要： Injection device for delivering a defined number (n) of equal doses of a fluid substance contained in a reservoir (P), the device having a housing (1) within which an arming mechanism and a dose delivery mechanism are arranged along the longitudinal axis of the housing, the housing (1) being coupled to an enclosure (3) adapted for receiving the reservoir (P) with the fluid substance, the arming mechanism comprising a setting sleeve (5) which is axially non-displaceable and rotatable around the axis of the housing in two opposite directions by a defined setting angle (a), the setting sleeve (5) being coupled with a spring (10) which is strained by the rotation of the setting sleeve (5) during arming of the device; the dose delivery mechanism comprising a screw ring (6) and a piston rod (4) which is non-rotatable and axially displaceable within the setting sleeve (5), the piston rod (4) cooperating with the screw ring (6) so that during arming of the device the screw ring (6) and the piston rod (4) are immobilized, and during delivery of each dose the piston rod (4) is displaced along the housing (1) by a defined distance due to unwinding of the spring (10) and rotation of the screw ring (6), the displacement of the piston rod (4) causing the fluid substance to be discharged from the reservoir (P). The injection device according to the invention is provided with blocking means preventing arming of the device for delivery of a subsequent dose after said defined number (n) of doses of a fluid substance have been delivered, the blocking means comprising at least one longitudinal protrusion (5.1) located near the distal end of the setting sleeve (5) on its inside surface, and at least one longitudinal arm (4.2) located at the proximal end of the piston rod (4), the at least one longitudinal protrusion (5.1) and the at least one longitudinal arm (4.2) mutually blocking each other after said defined number (n) of doses of a fluid substance have been delivered which prevents rotation of the setting sleeve (5) by the entire setting angle (α) in the arming direction.

摘要： An injection device includes a housing with an inspection window and at least two springs. One of the at least two springs is a driving helical spring. A spring block is connected to the housing and secured against rotation relative to the housing. A coupling tube extends above the spring block and above the housing. The injection device includes a plunger at least partially surrounded by the coupling tube. The driving helical spring is connected to the spring block. The coupling tube is at least partially surrounded by the driving helical spring. At least a portion of the proximal end of the plunger is narrower than a first internal diameter of the coupling tube and wider than a second internal diameter of the coupling tube. The rotatable dose knob, the spring block, the coupling tube, the plunger, and the driving helical spring are arranged coaxially.
