Abstract: An infusion set includes a base having a cannula for delivering a liquid medicament on a distal side for placing on a patient and a projection and recess and/or an annular groove on a proximal side. A connector for connection to an infusion device includes a protrusion on a distal side. The base and the connector are rotatably connectable to each other. The protrusion of the connector may be engaged with the projection and recess of the base such that, upon relative rotation between the connector and base, an acoustic and/or tactile signal indicates that the connector is connected incorrectly to the base; and/or the protrusion of the connector may be brought into engagement with the annular groove of the base such that the connector is rotatable relative to the base without causing noise and/or a tactile signal to indicate that the connector is connected correctly to the base.

Abstract: A multi-layer tube for an infusion set for dispensing a fluid includes an outer layer formed of polyurethane and an inner layer formed of high-density polyethylene and/or polypropylene.

Abstract: An administering device for administering a fluid product through the use of pressure, the device being modular, including a base unit and a cartridge, the base unit containing driving components and the cartridge adapted to be connected detachably to the base unit, wherein the cartridge has a fluid reservoir and a pressure monitoring device having a pressure sensor and a transfer device operably coupled to the pressure sensor, wherein the pressure monitoring device can be activated by an externally applied, alternating electromagnetic field, whereby data can be read, without contact, using the fluid pressure. In one embodiment, the pressure sensor contains a snap disk and the transfer device is an RFID transponder, wherein the base unit comprises a pressure reading device, which is constructed for producing a corresponding alternating electromagnetic field and, depending on the response to the alternating field, for determining a fluid pressure-dependent property of the transfer device.

Abstract: The present invention provides a catheter head including a cannula housing, a needle holder connectable to the cannula housing and a guide sleeve associated with the needle holder for positioning and guiding a connecting needle, and for being narrowly slide-guided over a portion of said cannula housing.
