Abstract: The present invention relates to secure paring of electronically controlled devices configured to communicate with each other. A medical system is provided comprising a first unit and a second unit, the system comprising a first communication link allowing a first group of data types to be transmitted between the first unit and the second unit, and a second communication link allowing a second group of data types to be transmitted between the first unit and the second unit. Different properties of the communication links may be used to ensure that certain data, e.g. during pairing of the two devices, can be transmitted in a more controlled way whereas other data can be transmitted in a less controlled way.

Abstract: The application provides an assembly comprising a housing (20) having an electrical housing connector (50) and a strip port (40) for a BGM sensor arranged in the vicinity of the electrical connector. The assembly further comprises an external electrical connector (60) adapted for releasable connection to the housing connector, wherein the external electrical connector comprises a portion (62) adapted to block the port opening when the external electrical connector is connected to the housing connector, thereby preventing insertion of a strip in the port when the two connectors are connected to each other. In this way it is prevented in a simple and cost-effective manner that a patient via an inserted strip is subjected to a too high voltage or current supplied to the circuitry of the electronic device.

Abstract: A graphical display for a medical monitor includes a graphical means for displaying past, present and future predicted values. The display may also show trend data and indicate whether a patient's condition or a monitored parameter is improving. The display may be pictorial, or be a combination of graphics and text. Colors, blinking, shading, and moving arrows may illustrate and communicate various information to a patient using the display. The display is well suited for use with various devices, including continuous blood glucose monitors. In some cases the display will be integral with the monitoring means, in other cases, typically bifurcated devices, the display will be used on a monitor that is interfaced or otherwise communicates with the sensor and measuring the patient's condition. In some cases the sensor might be remotely located on the patient and it might communicate with a processor that is interfaced with a monitor having the above described display.

Abstract: A liquid medication delivery device for, and a method of, delivering medication from a cartridge having a moveable piston at one end is disclosed. The piston has a first wall face that contacts the liquid in the cartridge and a second wall for engaging a piston rod that drives the piston. The first and second walls are moveable but the second wall tends to move more quickly then the first during administration of a dose of medication from the cartridge. To compensate for this difference in movement between the first and second wall faces, the rod first moves a distance corresponding to the amount that the first wall face must move to deliver the desired dose and then it continues to move past this position by an amount known as an overshoot distance. It is then retracted by a distance equal to the overshoot distance.

Abstract: The invention relates to an apparatus for self-treatment of diabetes. The apparatus is particularly advantageous by comprising a plurality of devices each of which has its own dedicated function corresponding to a number of acts which a diabetic must perform on himself. The individual devices are mutually interconnectible, and the combination comprises at least a body fluid analyzer and a dosing apparatus for administering a predetermined dose of insulin to the patient. Each of the devices may be provided in several sizes so that the user himself may combine the relevant devices of the relevant size with respect to the current need. This reduces the risk of forgetting parts of the equipment, and the confidence of using the equipment is enhanced because it is evident to the user that it is a complete apparatus consisting of unified parts.
