Blood glucose control systems are disclosed. A blood glucose control system can receive a glucose level signal from a glucose sensor operatively coupled to a subject. The system can decode encoded data of the glucose level signal to obtain the glucose level of the subject and the indication of the glucose trend. The system can automatically calculate the dose control signal using a control algorithm configured to calculate regular correction boluses of glucose control agent in response to at least the glucose level of the subject. The system can select a dose control signal encoding profile from a plurality of dose control signal encoding profiles and, based on the dose control signal encoding profile, encode the dose control signal such that the pump controller can read the dose control signal. The system can transmit an encoded dose control signal to the pump controller.

A data collection device comprises at least two optical sensors configured to detect tick marks of a medicament dose indicator of the medicament delivery device in their respective detection areas, and a processing arrangement configured to determine a current medicament dosage programmed into said medicament delivery device based on a count of the tick marks that pass through the detection areas of the optical sensors during programming of said medicament dosage into said medicament delivery device. A direction of travel of the tick marks may be identified, to determine whether the programmed dosage is increasing or decreasing. The apparatus may be arranged to identify a baseline dosage amount using a camera image of the medicament dosage indicator, so that a starting point for the count of tick marks can be determined. The medicament delivery device may be an injector pen.

The present invention relates to a method for contactlessly establishing a coupling between a medical apparatus (e.g., a hemodialysis apparatus or a peritoneal dialysis apparatus) and a remote control apparatus. An optical coupling signal is exchanged between the involved communication entities, in order to establish bijective, data-processing coupling between the remote control apparatus and the medical apparatus. Only after successful coupling is a remote control procedure initiated for remote control of the medical apparatus.

Provided is a wearable, self-contained drug infusion or medical device capable of communicating with a host controller or other external devices via a personal area network (PAN). The medical device utilizes a PAN transceiver for communication with other devices in contact with a user's body, such as a physiological sensor or host controller, by propagating a current across the user's body via capacitive coupling. The wearable nature of the medical device and the low power requirements of the PAN communication system enable the medical device to utilize alternative energy harvesting techniques for powering the device. The medical device preferably utilizes thermal, kinetic and other energy harvesting techniques for capturing energy from the user and the environment during normal use of the medical device. A system power distribution unit is provided for managing the harvested energy and selectively supplying power to the medical device during system operation.

An infusion pump system is disclosed. The infusion pump system includes an infusion pump and a controller device in wireless communication with the infusion pump, wherein the controller including instructions for controlling the infusion pump, wherein the instructions may be synchronized with a secure web portal.

A medicament delivery device is presented having a housing that is arranged to accommodate a medicament container; a drive unit operably arranged to act on the medicament container upon activation; an activation mechanism operably arranged to be operated by a user; an activation preventing mechanism operably arranged to prevent said activation mechanism to be activated; an identification module arranged to be operated by a user, which identification module is designed as an attachable unit to the medicament delivery device; mechanical keying elements arranged on said device and on said identification module designed to interact with each other when attaching said identification module; first electrical keying elements comprised in said identification module, wherein said electrical keying elements are capable of obtaining identification information, such that the identification information obtained is compared to stored data and authenticated by the identification module, and wherein the authentication causes a deactivation of the activation preventing mechanism to allow operation of the activation mechanism.

A method comprising: establishing a wireless connection between a first medical device and a second medical device, comprising: receiving, by the first medical device, via a short-range wireless technology protocol, connection information related to the second medical device; and establishing, by the first medical device, a wireless connection with the second medical device based on the connection information.

The present disclosure describes a closed-loop fluid resuscitation and/or cardiovascular drug administration system that uses continuous measurements and adaptive control architecture. The adaptive control architecture uses a function approximator to identify unknown dynamics and physiological parameters of a patient to compute appropriate infusion rates and to regulate the endpoint of resuscitation.
