Abstract: A syringe adapter is used for connecting a dosing syringe to a container in order to take up a fluid. The syringe adapter has a fluid delivery channel for creating a flow connection between the inside of the container and the inside of the dosing syringe. At least one ventilation channel of the syringe adapter is used for creating an air connection between the inside of the container and the container surroundings. In at least one of the channels a non-return valve is arranged, which allows the passage of media in an open position and in a closed position closes the channel. This results in a syringe adapter which has improved handing and in particular provides sufficient dosing precision.

Abstract: A filling needle can be used in a tube set for transferring a flowable medium, in particular a pharmaceutical product. The filling needle has a needle end for temporary insertion in a filling vessel. Furthermore, the filling needle has a connector end for connecting the filling needle to a filling vessel, via which the medium can be supplied to the filling needle. An inner tube lumen of the filling needle is defined by an inner tube layer made of silicone. The result is a filling needle that can be manufactured inexpensively.

Abstract: A tube mat comprises a plurality of tube portions having a tube longitudinal axis in each case and at least one web portion connecting two tube portions, the tube mat being produced in one piece.

Abstract: A medical injection device has an injection unit and an anti-rotation device. Said anti-rotation device is non-rotationally connected to a port and connection portion of the injection device so as to surround the outside thereof in the manner of a sleeve. As a result, an intuitively usable and operationally safe injection device is obtained. When a protective cap for an injection cannula of the injection unit is being removed from the port and connection portion, an unwanted rotation of the port and connection portion relative to the container about components of a plug-in connection arranged therebetween is safely prevented.

Abstract: The invention relates to a heat exchanger tube (1) which is a component of a heat exchanger of an oxygenator. The heat exchanger tube (1) comprises a tube body (2) consisting of thermoplastic polyurethane (PTU). The tube body (2) has a Shore hardness of greater than 60 D. This results in a heat exchanger tube optimised for use in a heat exchanger of an oxygenator.

The antenna is configured in an edge region of the carrier plate and running around the latter and around the electronic components. The result is a patient data sensor device which is more tolerable for the patient.

Abstract: The invention concerns a dosing system for adjusting a dose volume of a fluid medium. The dosing system has a longitudinal center axis, a dosing sleeve with at least one communication opening, a dosing plunger, which can move axially in the dosing sleeve between a retracted and a depressed position to take up and dispense the medium through the communication opening, and a retraction limiting element to delimit a maximum axial retraction path of the dosing plunger. The retraction limiting element in at least one position can be axially fixed to the dosing plunger and can move radially to the longitudinal center axis between an inner position, axially fixed on the dosing plunger, and an outer position relative to the dosing plunger. In the inner position, it is completely inside the dosing sleeve. Furthermore, the dosing system has an end stop arranged on the dosing sleeve for interaction with the retraction limiting element in the retracted position of the dosing plunger.

Abstract: During the transmission of sensor data of an implantable sensor with a measurement data recorder, an energy storage unit and a transmitter unit to an external data processing unit with a transmitter/receiver unit, a high-frequency energy carrier signal is firstly emitted from an energy supply unit. At least a part of the energy contained in the high-frequency energy carrier signal is stored in the energy storage unit of the implantable sensor. After the ending of the emission of the high-frequency energy carrier signal, a sensor measurement is carried out using the measurement data recorder of the implantable sensor. The measured sensor data are transmitted from the transmitter unit of the implantable sensor to the transmitter/receiver unit of the external data processing unit. The result is a transmission method, in which interference from the HF feed is avoided, with a compact design.

Abstract: A metering device is used for the metered administration of a flowable preparation together with a flowable carrier medium. A storage container for the preparation has at least one access opening. A metering plunger body can be moved in a sealed manner in the storage container between a starting position and at least one metering position. The metering plunger body is hollow. A metering sleeve has on a bottom side an eccentric metering sleeve opening. An inner plunger body has on the bottom side an eccentrically arranged plunger body opening. In a through relative rotation position of the metering sleeve relative to the inner plunger body a passage is provided between the inside of the storage container and the inside of the inner plunger body. In a closed relative rotational position this passage is closed. This results in a user-friendly and compact metering device.

Abstract: A medical fluid container of a flexible plastic material is produced as follows: at first, a plastic compound is produced from a heterogeneous mixture of a first, lower-viscosity raw polymer component having a first melt viscosity and a second, higher-viscosity raw polymer component having a second melt viscosity which is greater than the first melt viscosity. Then the plastic compound is extruded. The extrudate is confectioned. Finally, the confectioned extrudate is sealed to form the finished fluid container. A film tubing may serve as intermediate product for the medical container. The medical container or the film tubing thus produced has surface structures with a typical average size of 15 to 200 ?m. The production method requires little effort while fulfilling demanding requirements with respect to the stability of the produced fluid container.

Abstract: A gas exchange membrane is for use in an artificial lung. The membrane consists of a foamed, closed-cell material, in particular of silicone rubber. The membrane is produced by extruding a basic material which contains a foaming agent. The extrudate is then foamed. The result is a gas exchange membrane which has an increased gas exchange performance compared to known material due to the high permeability of the surface.
