Problems solved by technology

[0003] Thus, the control circuit of the medical device described in WO2009 / 024562 can be used with a series of prefilled disposable injection devices, but the RFID unit with the value sensor is housed in the drug container of the prefilled disposable injection device. Requirements significantly increase the cost of prefilled single-use injection devices

Embodiment Construction

[0040] Embodiments of the present invention are described below with reference to an insulin injection device. But the invention is not limited to this application, but could equally be configured with injection devices or other types of medical devices that dispense other medicines.

[0041] Figure 1 is an exploded view of an injection device 1, which may for example represent Sanofi's Solostar(R) insulin injection pen.

[0042] The injection device 1 of Figure 1 is a prefilled disposable injection pen comprising a housing 10 and housing an insulin container 14 to which a needle 15 can be attached. The needle is protected by an inner needle cover 16 and an outer needle cover 17 which in turn may be covered by a cover 18 . The dose of insulin to be expelled from the injection device 1 can be selected by turning the dose knob 12, and the selected dose is then displayed through the dose window 13 in multiples of, for example, so-called International Units (IU), where one IU is ...

Abstract

Pen-type drug injection device (1) and attachable electronic add-on monitoring module (2) for monitoring and logging dose setting and administration, the module comprising a housing, an electromechanical switch arrangement (110), the electromechanical switch arrangement comprising a main body (111) and a switching member (113), the switching member having a protrusion (118) arranged to protrude from the main body so as to contact a surface of the injection device while the module is attached to the injection device, and a biasing member (115) biasing at least a part of the main body of the electromechanical switch arrangement against the injection device while the module is attached to the injection device.

Description

technical field [0001] The invention relates to an attachment device for attachment to an injection device. Background technique [0002] There are a variety of diseases that require conventional treatment with injectable medicines. Such injections may be performed using an injection device applied by medical personnel or by the patient himself. As an example, type 1 and type 2 diabetes can be treated by the patient himself by injection of insulin doses, eg once or several times a day. For example, prefilled disposable insulin pens are available as injection devices. Alternatively, reusable pens can be used. Reusable pens allow replacement of empty cartridges with new ones. Either pen may have a set of single-use needles that are replaced before each use. The insulin dose to be injected can then be selected, eg manually, in the insulin pen by turning the dose knob and observing the actual dose from the dose window or display screen of the insulin pen. Then, inject the ...
