An ambulatory medical device and a method of communication between medical devices are disclosed. In one embodiment, the medical device includes a module for communication with at least a second medical device wherein the module for communication is adapted to be activated by a value of a physiological parameter of an animal. In one embodiment, the method of the present invention involves a first medical device and at least a second medical device wherein the communication between said medical devices is activated by a value of a physiological parameter of an animal.

Ambulatory medical device and method for communication between medical devices

An infusion pump device and method for filling a fluidic system of the infusion pump with liquid medicament prior to infusion operation is presented. A control unit causes the infusion pump to: (a) bring a pump to an initial state; (b) switch a valve to a first state connecting a secondary reservoir to a first conduit and a primary reservoir; (c) retrieve medicament from the primary reservoir; (d) switch the valve to a second state connecting the secondary reservoir to a second downstream conduit; (e) expel the secondary reservoir contents into the second downstream conduit; (f) switch the valve to the first state; (g) retrieve the primary reservoir medicament; (h) switch the valve to the second state; and (i) expel the secondary reservoir contents into the second downstream conduit by shifting a piston to the initial position.

Infusion pump and method for improved filling of a fluidic system

A method for adjusting a sensor, continuous sensor or automatic measuring system in an interstitium including the steps of adjusting the steepness of a measuring curve and a standard offset (standard axis intercept) prior to the use of the sensor, continuous sensor or measuring system, and adapting the offset by a point calibration by using a reference measure or value during the use. The present invention encompasses sensors, continuous sensors or automatic measuring systems calibrated or adjusted in accordance with the method, and in some embodiments, the offset adjusted prior to use is rectified according to the difference between a value determined by the sensor, continuous sensor or measuring system taking into account the standard steepness and the reference value.

Calibration of sensors or measuring systems

A dosing device for an infusion system comprises a dosing unit having a variable volume and at least one opening in fluid connection with the variable volume, through which opening the variable volume can be filled with a substance or the substance can be dispensed from the variable volume. The dosing device is operable in a first state for filling the substance from a supply conduit, in a second state for preventing filling and dispensing, or in a third state for dispensing through a dispensing conduit. No direct fluid connection exists between the supply conduit and the dispensing conduit at any time. Methods for dosing a substance with the dosing device.

Dosing device for an infusion system and method thereof

A sensor device for use in a medical fluid delivery system, or an infusion pump device, comprises a fluidic chamber with a deformable cover closing at least an area of the chamber and an optical detection system comprising at least one light emitter for emitting one or more incident light beams and a sensor unit for monitoring one or more reflected light beams is presented. In a pressurized state of the fluidic chamber, the deformable cover is deformed such that it forms an inflexion point area within the deformed cover. The one or more incident light beams emitted by the light emitter are directed on the cover such that the one or more incident light beams are reflected essentially in the inflexion point area.

Sensor device for use in a medical fluid delivery system

A dosing unit for an infusion pump device is disclosed having a piston pump with a pump cylinder and a plunger arranged within said cylinder, coaxially arranged along a longitudinal axis. The plunger has a shaft with a thread and the cylinder has a threaded sleeve part with a thread. The two threads engaging with each other in such a way that a rotational movement of the plunger around the longitudinal axis results in an additional linear displacement of the plunger along said longitudinal axis. A separate bias force element biases the two threads in regard to each other along the longitudinal axis, such that the threaded engagement of inner thread and outer thread is free of play independent of a direction of a rotational movement and linear displacement of the plunger in regard to the cylinder.

Dosing unit for an ambulatory infusion device

At least one dosing unit for an infusion pump is disclosed having a piston pump with a pump cylinder, a plunger arranged within said cylinder, and a plunger driving part provided for transmitting rotational torque from a driving unit to the plunger without itself being linearly displaced. The cylinder, the plunger and the plunger coupling element are coaxially arranged along a longitudinal axis and rotatable around said axis in regard to static parts of the dosing unit. The plunger and cylinder each having threads which engage with each other in such a way that a rotational movement of the plunger around the longitudinal axis results in a linear displacement of the plunger along the longitudinal axis. The dosing unit also having first coupling parts associated with the cylinder and second coupling parts associated with the plunger.

A sensor may include a substrate having a sensing portion defining a sensor thereon and a circuit mounting portion defining at least one electrically conductive pad that is electrically connected to the sensor. The sensor may be configured to produce a signal indicative of a condition of the patient. An anisotropic medium may be disposed on the circuit mounting portion and may be electrically conductive in a direction through the medium and electrically insulating in directions along the medium. An electrical circuit may be mechanically mounted to the circuit mounting portion of the first substrate via the anisotropic medium with at least one electrically conductive terminal juxtaposed over the at least one electrically conductive pad. The anisotropic medium may establish local electrical contact between the at least one electrically conductive terminal and the at least one electrically conductive pad.

Sensor for monitoring a condition of a patient

A diabetes care system for detection of an analyte and method for selective data transmission are disclosed. The diabetes care system has a mobile component and a base station, wherein a data transmission occurring between the mobile component and the base station within a time interval in which a wireless communication link exists, wherein is selectively performed in such a manner that within the time interval, a first partial set of the data is transmitted from the mobile component to the base station. The first partial set is selected using a processor-controlled selection algorithm in such a manner that the data transmitted in the time interval is representative of the entirety of the data stored in the mobile component.

A dosing unit for an ambulatory infusion pump device is presented. The dosing unit comprises a cylinder pump with a cylinder and a piston arranged in the cylinder. The piston has a shaft with a first threaded segment interacting with a threaded portion of the cylinder and can be displaced along a longitudinal axis of the cylinder by rotating the piston in regard to the cylinder around the axis. Furthermore, the piston allows for the relative or absolute determination of the longitudinal and/or rotational displacement of the piston in regard to the cylinder. In one embodiment, the piston shaft comprises a second segment provided with optically detectable markings that allow the monitoring of the longitudinal and/or rotational displacement of the piston in regard to the cylinder.
