Embodiment Construction

[0042] In the figures, identical reference numerals designate identical or functionally identical elements.

[0043] For reasons of simplification of the illustration, only parts of the illustrated embodiment are shown by means of Figure 9 a), b) Injection equipment as described. For parts not shown refer to Figure 9 a), b).

[0044] figure 1 is a schematic partial cross-sectional view for explaining the injection device according to the first embodiment of the present invention.

[0045] As already explained, the pen-shaped sheath 3 serves to receive the syringe holder 2 , which in turn can include a medicament syringe. Arranged in the pen-shaped sheath 3 is an injection mechanism which has a metering sleeve 4 by means of which the metering quantity to be injected can be predetermined manually by means of a rotational movement. During injection, the dosing sleeve 4 performs a rotational movement, more precisely, in the first embodiment, relative to the pen-like sheath 3...

Abstract

The invention relates to an injection device and a corresponding injection measurement method. The injection device is equipped with: a pin-like shell (3) for receiving a cartridge holder (2); an injection mechanism, which is provided in the pin-like shell (3) and which has a dosing sleeve (4), by means of which a dosing quantity to be injected can be predefined and which is designed in such a waythat it performs a rotary movement during the injection; a selector apparatus (5a) connected to the dosing sleeve (4) for setting the dosing quantity to be injected; an injection button (6a) connected to the selector apparatus (5a) for applying an injection force; and an optical sensor apparatus (100-105) for detecting the rotary movement of the dosing sleeve (4) during the injection of the dosing quantity, which sensor apparatus has a signal processing apparatus (102) for determining and storing the injected dosing quantity on the basis of the detected rotary movement of the dosing sleeve (4). The injection button (6a) has a switch apparatus (101) sensor apparatus (100-105), by means of which the optical sensor apparatus (100-105) can be activated as the injection force is applied.

Description

technical field [0001] The invention relates to an injection device and a corresponding injection measurement method. Background technique [0002] Although any injection device can also be used, the invention and the problem on which it is based are explained with the aid of a pen-like injection device for injecting insulin. [0003] Pen-shaped injection devices for the subcutaneous injection of liquid medicaments and active substances, such as insulin, have been available on the market for many years. Such injection devices exist in two principle variants. On the one hand, there is a pre-filled version which is completely removed after it has been completely emptied, and on the other hand, a version which makes it possible to exchange the remaining active substance syringe after emptying and Use the mechanical part again. [0004] Figure 9 a), b) are schematic diagrams of exemplary injection devices, more precisely, Figure 9 a) is the case where the preselected ration...
