Benefits of technology

The patent aims to improve the handling and management of injection locations. It introduces a heatmap that is displayed to users before they perform an injection. This allows users to check the intended injection location in relation to previous injection locations. The technical effect is to facilitate the injection process and improve the accuracy of injections.

Problems solved by technology

In such recurring self-injection regimens it is very important that the user does not inject the drug at the same location every time or too often as this may cause ‘pockets’ of the drug to gather under the skin, cause hard lumps, and / or cause extra fat deposits to develop as well as the onset of lipohypertrophy and / or similar skin / tissue damages (that may change the way the liquid drug is absorbed by the body at that location), and so on.
However, there is scientific evidence that a significant number of users may still forget where the last injection was made (see e.g. Diabetes Meab.
Some users may also be relatively young children, which may have a harder time sticking rigorously to a recommended rotation scheme and / or remembering it fully all the time.

Embodiment Construction

[0089]Various aspects and embodiments of a position determination device for and methods of determining and registering an injection location of administered liquid drug administration on a user and calibration of such position determination devices as disclosed herein will now be described with reference to the figures.

[0090]When / if relative expressions such as “upper” and “lower”, “right” and “left”, “horizontal” and “vertical”, “clockwise” and “counter clockwise” or similar are used in the following terms, these refer to the appended figures and not necessarily to an actual situation of use. The shown figures are schematic representations for which reason the configuration of the different structures as well as their relative dimensions are intended to serve illustrative purposes only.

[0091]In that context, it may be convenient to define that the term “proximal direction” in the appended figures is meant to refer to the direction of the position determination device (and its asso...

Abstract

The present invention relates to a position determination device (100) (and system) for determining and registering an injection location of a liquid drug administered on a body part of a user, wherein the position determination device (100) (and system) comprises a position determination element (110) configured to provide a position signal representing a current location of the position determination device (100), and one or more processing units (150) configured to derive data representing an actual injection location based on the user in response to a current location being determined by the position determination unit (110).

Description

FIELD OF THE INVENTION[0001]The invention relates generally to embodiments of a position determination device for and method of determining and registering an injection location of self-administered liquid drug administration on a user. Further the invention relates to calibration of such position determination devices.BACKGROUND OF THE INVENTION[0002]A growing number of people have a condition involving liquid drug delivery administration where the user themselves deliver the relevant liquid drug (i.e. self-administration) by injection at an appropriate injection location or site using an injection device or the like.[0003]Preferably, the liquid drug to be delivered is insulin but the invention is applicable to all liquid drug delivery devices where a user administers a drug on at least a somewhat regular basis, e.g. several times a day or less frequent like a number of times in a week, etc., by injection into an appropriate body part.[0004]Other examples of user-administered liqui...
