Embodiment Construction

[0039] Hereinafter, embodiments will be described with reference to an auto-injector. However, the present disclosure is not limited to this application and may equally apply to injection devices expelling other medicaments, or other types of drug delivery devices, such as syringes, prefilled syringes, needle-free injectors, and inhalers.

[0040] will now refer to figure 1 The injection device 10 according to the embodiment will be described. In some embodiments, injection device 10 is a single use autoinjector 10 . Autoinjector 10 has a proximal end P and a distal end D. The proximal end P is directed towards the injection site of the patient during injection, while the distal end D is directed away from the injection site.

[0041] The autoinjector 10 comprises a body 9 and a cover 12 (also referred to herein as an outer needle cover or ONC 12) and a further cover 12' (also referred to herein as an inner needle cover or INC 12'). The main body 9 comprises an outer casin...

Abstract

A drug delivery device comprising: a body and a movable component arranged inside the body; a dosage selection and injection mechanism setting the position of the movable component inside the body depending on a selected dosage; a non-contact sensor configured to output signals indicative of the position of the movable component inside the body; and a processor configured to receive the signals output from the non-contact sensor and to determine based on the signals whether the movable component is either in an initial position inside the body corresponding to no selected dosage or in a selected dosage position, wherein upon determining that the movable component has changed its position back from the selected dosage position to the initial position, the processor is configured to cause anindication to be output which informs a user regarding a dwell time of the drug delivery device.

Description

technical field [0001] The present disclosure relates to a drug delivery device configured to notify a user of a dwell time (eg elapsed dwell time) after injection of a medicament. Background technique [0002] There are various diseases that require regular treatment by injecting medicaments. Such injections can be performed by using an injection device, which is applied by medical personnel or by the patient himself. [0003] Injection devices (ie, devices capable of delivering medicament from a medicament container) generally fall into two categories - manual devices and auto-injectors. [0004] In manual devices - the user must provide mechanical energy to drive fluid through the needle. This is usually done with some form of button / plunger that must be continuously depressed by the user during the injection. This method presents a number of disadvantages to the user. If the user stops pressing the button / plunger, the injection will also stop. This means that if the...
