Monitoring device for drug application with a drug pen, with logging, communication and alarms
First Claim
1. A device for monitoring the application of a drug to a patient by means of a drug pen, whereby the drug pen comprises a front end provided with an injection needle and a rear end provided with an actuation pushbutton, comprising:
- a body which can be dismountably coupled to the drug pen, whereby the body comprises;
an essentially frustoconical gasket having an orifice configured for housing therein the actuation pushbutton of the drug pen;
a coupling portion having a through orifice configured for housing the gasket therein such that a compression of said gasket takes place for compressing it firmly around the actuation pushbutton;
a cover portion configured for coupling to the coupling portion;
an injection detection means implemented as an actuation detector, whereby the actuation detector is a mechanical button provided in the cover portion, configured for detecting a pushing action such that the injection detection means is configured to determine when a drug injection is carried out by detecting the pushing action; and
a processing means configured for storing the date and time of the drug injection when the drug injection detection means detects that a drug injection is carried out,wherein;
the processing means is adapted to store a dataset including the time and date of the drug injection;
the device comprises means for monitoring, at the time of application, the temperature of the drug, and the processing means is adapted to store this temperature into the dataset and whereby the device further comprises alarm means adapted to warn a user of the pen in the case that the detected drug temperature is above or below a preset threshold and if no or a wrong dose is applied or the drug injection is uncompleted and when the drug injection is completed to confirm such correct application;
the device further comprises one or more accelerometers adapted to detect the three dimensional orientation of the drug pen when the device is mounted to the drug pen, whereby the processing means is adapted to store the three dimensional orientation of the drug pen into the data set;
the device further comprises a drug kind detection means comprising a color sensor and being adapted to automatically detect the kind of applied drug when a drug injection is detected, whereby the kind of drug is identified via a color label provided at the pushbutton of the pen, and whereby the processing means is adapted to store the detection result of the drug kind detection means into the dataset; and
the pushbutton to which the body of the device is coupled, before being actuated, is retracted by turning it backwards a distance in proportion to a drug dose to be injected, as the user turns the pushbutton, an indication window shows the user a number of drug units that is being charged for injection.

Abstract
The present invention provides a device (1) for monitoring the application of a drug to a patient by means of a drug pen (100), whereby the drug pen comprises a front end provided with an injection needle and a rear end provided with an actuation pushbutton, the device comprising a body (2) which can be dismountably coupled to the pen; an injection detection means determining when a drug injection is carried out; and a processing means configured for storing the date and time of the injection when the injection detection means detects that a drug injection is carried out, whereby the body is configured to be coupled to the pushbutton of the pen such that the pushbutton is actuated by pushing directly on the body, whereby the injection detection means is implemented as actuation detector configured for detecting said pushing action.
