Abstract

A plug-on body which can be plugged onto a device for administering a settable dosage of an injectable product, the plug-on body including a first plug-on body section extending axially in the direction of a plug-on body axis for fixing the plug-on body to a dosing and activating means, a shifting stopper formed by the first plug-on body section and operating by positive lock for axially fixing the plug-on body with respect to at least one shifting direction, a rotational stopper formed by the first plug-on body section and operating by positive lock for fixing the plug-on body against rotating, a second plug-on body section extending behind the first plug-on body section in the direction of the plug-on body axis, wherein said second plug-on body section forms an optics system for reading a dosage scale on a dosing element of the device which serves to set the dosage.

Claims16

Dependent claims

An administering device assembly comprising:

a) an administering device having an outer casing, a rotating dosing mechanism for selecting a dose amount to be administered, an activating means for initiating administration of the injection, a dose delivery end, and a protrusion formed on the surface of the outer casing arranged distal to the dose delivery end;
b) a first plug-on body section to be positioned on the outer casing of the device distal to the injection delivery end, said first plug-on body having an elongated groove extending along a longitudinal axis, wherein the elongated groove has a narrow portion for sliding accommodation of the protrusion formed on the surface of the outer casing of the device and a widened portion for accommodating the protrusion to lock the plug-on body to prevent axial and rotational movement of the plug-on body in relation to the outer casing of the device;
and
c) a second plug-on body section fixedly attached to the first plug-on-body section and positioned proximal to the activating means of the device and distal to the injection delivery end, wherein the second plug-on body section extends over the rotating dosing mechanism of the device, thereby preventing adjustment of the rotating dosing mechanism of the device, and wherein said second plug-on body section provides an optics system for reading a dosage scale of the rotating dosing mechanism of the device.

1 more element

A device for administering a settable dosage of an injectable product, said device comprising:

a) a casing;
b) a reservoir, formed or accommodated by the casing, from which a product dosage is administered;
c) a delivering means for delivering the product dosage to be administered from said reservoir;
d) an activating means, connected to the casing, with which the delivering means can be activated;
e) a dosage mechanism for selecting a dose amount to be administered;
f) a protrusion formed on the surface of the casing proximal to the dosage mechanism;
g) a dose delivery end arranged distal to the protrusion;
and
h) a plug-on body which is arranged distal to the dose delivery end and forms an optics system for reading a dosage scale of the device when the plug-on body is connected to the casing, the plug-on body having an elongated groove extending along a longitudinal axis of the device, wherein the elongated groove has a narrow portion for accommodating the protrusion formed on the surface of the outer casing of the device and a widened portion for accommodating the protrusion to lock the plug-on body to prevent axial and rotational movement of the plug-on body in relation to the casing of the device, wherein when the plug-on body is locked, said plug-on body is arranged over the dosage mechanism thereby preventing its adjustment.
