Abstract: A sensor system for a volumetric pump operating according to the linear peristalsis principle includes at least one sensor unit; at least one sensor transmitter unit; and a sensor output signal processing unit. The sensor transmitter unit is arranged to apply a detection variable varying as a function of a travel position to the sensor unit along a predetermined travel along which a fixedly arranged sensor unit and a movably arranged sensor transmitter unit or a movably arranged sensor unit and a fixedly arranged sensor transmitter unit are moving relative to each other. The sensor unit is configured to output a detection signal corresponding to a travel position on the basis of the varying detection variable. The sensor output signal processing unit is arranged to receive the detection signal output by the sensor unit and discriminate at least three travel positions on the basis of the received detection signal.

Abstract: Valves are described for intravenous (IV) catheter assemblies for controlling fluidic flow. The valve can prevent blood leakage in multiple access use situations. A thinner area of the valve around a slit is provided. The thicker area of the valve is to provide rigidity to the valve so that it is able to return to a closed configuration when a Luer connector is removed.

The valve opener can be used with a range of needle sizes.

Abstract: Needle assemblies are generally discussed herein with particular discussions extended to needle assemblies having a tip protector with a plurality of wall surfaces for preventing contact with the needle tip from a side. Aspects of the tip protectors discussed herein include a first protector body having an arm for blocking a needle tip surrounded by a second protector body having a plurality of wall surfaces.

Abstract: A needle assembly includes a catheter hub, a catheter tube extending distally from the catheter hub, and a needle hub having a needle having a needle tip extending out the catheter tube. A protective cap is positioned with the catheter hub and covers the catheter tube and the needle tip. The protective cap has a casing having a casing body, a first opening at a proximal end of the casing body, a proximal cavity having the needle tip and the catheter tube located in the proximal cavity, a second opening at an end opposite the first opening and opening into a distal cavity, and a rim at the second opening. A lid is removably attached to the rim at the second opening to seal a solution inside the distal cavity. The solution is dispensable from the distal cavity following separation of the lid from the rim.

Abstract: A sensing system for sensing a potential complication at a venous catheter site. The system includes a sensor module for attachment at the site of the catheter. The sensor module includes a pressure sensor configured to generate pressure data representing measured pressure at the site of the catheter; a temperature sensor configured to generate temperature data representing measured temperature at the site of the catheter; and two pairs of bio impedance electrodes that generate bioelectrical signals representing bioelectrical activity at the site of venous catheter and a transmitter for transmitting the pressure, temperature data and bio impedance data.

Abstract: An injection device includes a cylinder having a cavity for receiving a liquid. A passage is connected to the cavity for inflow and/or outflow of the liquid. The passage can be connected to an injection component. A shut-off valve has a valve body and a flexible sealing ring with an opening. The valve body, proceeding from a release position in which the passage is freed, is at least partially movable through the opening of the sealing ring to a blocking position in which the valve body engages behind the opening so that movement of the valve body to the release position is blocked and the passage is sealed off against proximally directed flow. An adapter body is connected to the cylinder. The shut-off valve is arranged at a proximal end of the adapter body and at a distal end of the cylinder. The device can be used in a syringe.

Abstract: Peripheral intravenous catheter assemblies with capabilities for both blood sampling and catheterization can have a blood collection holder with a needle hub attached to a catheter hub. The combination catheter assembly and blood sampling holder can be called a catheter and holder assembly. Blood sampling can be done directly through the needle and the blood collection holder after cannulation. After blood sampling, the blood collection holder and the needle can be removed, leaving the catheter hub with the patient for IV infusion. The catheter hub can be a straight catheter hub or can include a side fluid port for use in as an integrated IVC.
