Embodiment Construction

[0069] Figure 1 discloses a prior art medical delivery device forming an injection pen 1 comprising a medicament filled cartridge 2 housed in the distal portion of the pen. The main housing part 4 of the device holds the mechanism for setting and injecting a specific dose of medicament from the cartridge 2 . Cartridge 2 comprises a channel in the distal neck, which is sealed by a pierceable sealing member 5 . The cartridge also comprises a slidably mounted piston 6 adapted to slide towards the distal portion of the container 2 when a force is exerted on the piston 6 in the distal direction. During administration, the medicament is delivered through the outlet, which in depicted form is shown as an injection needle assembly comprising a needle cannula 3, which is releasably secured to the distal portion of the pen. In the form depicted, the dose size selector 9 in the form of a dose dial knob is turned to set the correct dose size. The injection pen also comprises an actuator...

Abstract

The present invention relates to medical delivery devices for administering a dose of a drug into the body of a subject user and incorporating a time lapse indicator which is configured for indicating after administration that a dose of the drug actually has been administered and for maintaining this indication until lapse of a pre-defined time interval. The time lapse indicator disclosed is based on a pressure sensitive substance which exhibits a change in a visual property in response to an action associated with administering a dose and wherein the pressure sensitive substance exhibits a further change in a visual property after lapse of a pre-defined time interval subsequent to said action.

Description

technical field [0001] The present invention relates to a medical delivery device for supplying a medicament into the body of a subject user, wherein the indicating device is configured to indicate after administration that a dose of medicament has been delivered, and to maintain this indication until a predefined time interval. Background technique [0002] Some medicaments, such as insulin, are commonly self-administered using medical delivery devices, such as injection pens. The average diabetic will require multiple injections of insulin over the course of a week or day. However, typical injection devices do not solve the problem of the user not being able to remember when the last injection was taken. [0003] Even shortly after administering a dose of insulin, the user sometimes wonders whether he actually administered the injection. This may be minutes or even hours after the expected time for administration of the dose. Therefore, there is a potential danger that...
