Abstract: A method for detecting occlusions including providing a signal that characterizes a conveying status of a fluid, and determining from a difference between two such signals whether an occlusion has occurred. The invention encompasses a device for detecting an occlusion including a sensor for sensing a fluid flow parameter and/or an operational parameter of the device and an evaluation unit for processing the output of the sensor.

Abstract: An ambulatory infusion device for the infusion of a liquid drug into a patient's body over an extended time period is disclosed. The infusion device provides a housing having a cartridge compartment designed to receive a cartridge, a drive having a plunger adapted to engage a plug of the cartridge and to displace the plug within the cartridge in a controlled way, and an electronic controller controlling operation of the drive. The infusion device further has a position memory which stores at least one stored loading position of the plunger, and in which the controller retrieves a stored loading position from the position memory and controls the drive to displace the plunger into the retrieved loading position. A system for ambulatory drug infusion comprising such an ambulatory infusion device as well as a filling apparatus and a method for loading a cartridge into such a device are also disclosed.

Abstract: A transfer device for use in transferring a substance from a storage container into an ampoule that can be inserted into a device for dosed administration of substance, the transfer device including an adapter for securing the storage container and the ampoule relative to each other and coupling them to be able to transfer a substance contained in the storage container into the ampoule, and a displacement element that can act on the storage container such that the substance contained in the storage container is forced out of the storage container and transferred into the ampoule via the coupling formed by the adapter.

Abstract: An administering device with an osmotic drive for administering an injectable product includes a housing with a first chamber containing a solvent, a second chamber containing a solution and a product chamber for accommodating the product. A semi-permeable membrane is disposed between the first chamber and the second chamber. The second chamber is adjoined by a delivery means for delivering product out of the product chamber. A triggering device for triggering the osmotic drive includes an impermeable separating means between the first chamber and the second chamber. The delivery means is slidable relative to the housing along a longitudinal axis of the housing.

Abstract: An auxiliary adapter with which a medical appliance carrying an adhesive can be applied to the skin of a human or animal body, wherein the adapter may be connected to or integral with the medical appliance and, in some embodiments, includes a fixing structure or portion generally correlative with a pivot mechanism associated with the medical appliance. Using the adapter, the medical appliance may be applied to the skin surface ergonomically and comfortably, and as precisely and securely as possible.

Abstract: An infusion arrangement and method for administering a medicinal substance to a patient, the arrangement including a catheter head with an underside for securing to the patients' body, a cannula extending from the underside of the catheter head for insertion into the patient's body, a connector carried on the catheter head for establishing a releasable fluidic connection to an administration device, the administration device rotatably coupled to the connector, wherein the administration device carries, on peripheral areas of the underside thereof, at least one adhesive suitable for fixing the administration device in a selected position relative to the patient's body.

Abstract: A method for detecting occlusions including providing a signal that characterizes a conveying status of a fluid, and determining from a difference between two such signals whether an occlusion has occurred. The invention encompasses a device for detecting an occlusion including a sensor for sensing a fluid flow parameter and/or an operational parameter of the device and an evaluation unit for processing the output of the sensor.

Abstract: A computer-aided insulin pump by which a basal delivery profile can be automatically adapted in steps in the event of a travel-dependent time shift, in that the local time at the destination is communicated to the pump controller which uses the time, in accordance with a stored algorithm, to calculate one or more changeover delivery profiles which are then temporarily used for automatic control of the insulin pump until the changeover of time has been completed.

Abstract: A device for automated subcutaneous delivery of insulin into a patient's body, wherein the device includes an infusion cannula for subcutaneous introduction of the insulin into the body, an insulin reservoir having an amount of insulin which is non-fatal for a person on short-duration subcutaneous administration, and an automated conveying device for conveying the insulin from the reservoir to the infusion cannula which, after manual actuation by the patient, starts automatically conveying the insulin, after a delay of from four to eight hours, and conveys the complete amount of insulin in the reservoir to the infusion cannula within a period not exceeding four hours. Methods of making and using the device are encompassed.

Abstract: A modular infusion pump for administering a product, including a pump housing, a reservoir to contain the product, a delivery device associated with the pump housing to deliver the product from the reservoir, an energy source for the delivery device, another housing separate from the pump housing for receiving the energy source, and a transmission for transmitting energy from the energy source to the delivery device.

Abstract: A device integrated with and/or operably coupled to a medical device, including an acoustic element for detecting a sound associated with the medical device to monitor and/or assess the performance and/or condition of the medical device. The invention encompasses a method for assessing the operation, performance and/or condition of a medical device wherein a sound associated with the medical device is detected and analyzed.
