摘要： An infusion apparatus for delivering medication includes a housing, a drive mechanism, a force sensor, and a transfer element. The drive mechanism comprises first and second conveying elements, the second conveying element for advancing a plug in a reservoir in the distal direction, the first conveying element with limited axial movement relative to the housing but rotatable to cause an ejecting or resetting movement of the second conveying element. The force sensor is arranged along a central axis between the housing and the proximal end of the drive mechanism. The transfer element is axially arranged between the force sensor and the first conveying element and the force sensor bears axial forces exerted by the ejection movement. The second conveying element moves the transfer element away from the first conveying element against the bias of a restoring force such that the force sensor bears axial forces exerted by the resetting movement.

摘要： 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).

摘要： The invention relates to a device for the dosed administration of an injectable product. Said device comprises a housing with a reservoir for the product and a plunger that expels the product from the reservoir when displaced in an advance direction towards a reservoir outlet. A drive element can be displaced along an axis of displacement, thereby pushing the plunger in the direction of advance. A dosing element is mounted in the housing to be glidingly movable, preferably in a rotatable manner, along the axis of displacement in order to adjust a product dosis to be released during administration. The device according to the invention is further characterized in that a bearing surface between the dosing element and the housing is lubricated and that at least one lubricant reservoir is disposed on the one bearing surface.

摘要： The invention relates to an administration device for administering an injectable product. Said device comprises a housing containing a reservoir for the product, a plunger that is located in the reservoir so that it can be displaced in a feed direction, a plunger rod that can be displaced in the feed direction and that acts on the plunger and a locking mechanism that prevents the displacement of the plunger rod against the feed direction. The locking mechanism comprises or consists of a first locking device, formed by the plunger rod and a second locking device that cannot be displaced in relation to the housing against the feed direction, said two devices being permanently engaged with one another. Preferably, in addition, the second locking device cannot be displaced in relation to the housing in the feed direction.

摘要： The invention relates to a device for dosing the administration of an injectable product comprising: a) a housing (1, 5) with a reservoir (2) for the product; b) a piston (3) that pushes out the product from the reservoir (2) when it is displaced towards an outlet (4) of the reservoir (2) in the advance direction; c) a toothed bar (10) with a first row of teeth (11) and a second row of teeth (12) that displaces the piston (3) in the advance direction; d) a drive member (20) that can be displaced in and against the advance direction in relation to the housing (1, 5), which entrains the toothed bar (10) when it is displaced in the advance direction and e) blocking means (6) which is not displaceable in relation to the housing (1, 5) and which cooperates with one of the rows of teeth (11, 12) in such a way that it prevents the displacement of the toothed bar (10) against the advance direction and enables the displacement of the toothed bar (10) in the advance direction. The second row of teeth (12) has an elongated tooth space (17a) in which the blocking means (7) cooperating with the second row of teeth (12) engages when the toothed bar (10) is placed in a starting position before effecting a first administration.
