Abstract: Embodiments of a catheter insertion device are discussed comprising: an approximately hollow cylindrical catheter sleeve, at whose distal end a catheter is attached; a needle sleeve with a hollow needle, which is attached thereto and which, when ready for use, extends through the catheter sleeve and the catheter, and; a needle protective element that is arranged inside the catheter sleeve while being able to move on the needle. Said needle protective element has an engaging section that engages with an engaging device, which is formed in the vicinity of the needle tip, when the hollow needle is withdrawn from the catheter sleeve. A check valve is placed inside the catheter sleeve between the catheter and the needle protective element. The hollow needle, when ready for use, extends through said check valve, and the check valve automatically closes once the needle is withdrawn.

Abstract: Blood collection assemblies with safety features are disclosed. The assemblies have a housing for receiving a vacutainer, which has a septum that penetrates a sharp needle tip. The disclosed assemblies further have a shield for covering the other end of the needle following use to prevent accidental contact with the distal needle tip. The shield is spring loaded so that the spring force moves the shield over the needle. The shield can be secured or held in an initial position and allowed to move to cover the needle upon actuation or activation of an activator unit.

Abstract: The present disclosure relates to a catheter device comprising a catheter hub in which a valve member is disposed, a needle fixed in a needle hub, the needle extending through the valve member in the catheter hub in a ready position, and a tubular receptacle in which the needle hub is displaceably guided and biased by a spring in a proximal direction relative to the receptacle, wherein the needle hub is releasably held in the ready position in the receptacle against the force of the spring by frictional force between needle circumference and catheter or catheter hub, which frictional force is reduced on retraction of the needle through the catheter hub such that the force of the spring prevails.

Abstract: A piston pump is described for pumping a fluid. The pump includes at least one cylinder having a piston movable inside the cylinder along the longitudinal axis of the cylinder by a drive, each cylinder having at an end face a mounting flange having at least one cylinder opening, and a chamber having a volume that changes when the associated piston is moved in the cylinder. The piston pump has an inlet port for supplying and an outlet port for draining the fluid. A rotatable valve plate is arranged on the other side of the mounting flange. The mounting flange has at least one passage in the region of the inlet port and the outlet port, respectively, through which the fluid can flow between the inlet port and/or the outlet port and the other side of the mounting flange. The valve plate has fluid-transporting means by which, upon rotation of the valve plate at least one cylinder opening can be connected to a passage of the inlet and/or the outlet port.

Abstract: An injection device (10) for administering a liquid has a barrel (12) with an outlet (20) for the liquid, and a piston (14) arranged in the barrel (12). The piston is designed to force the liquid out from the outlet (20) by displacement into the barrel (12). The injection device (10) has an overpressure protection with a sensor (24) and with an actuator (26). The sensor (24) detects the pressure of the liquid in the barrel (12) directly or indirectly. The actuator (26) prevents a further increase in the pressure of the liquid.

Abstract: Method, system and device involving a needle device with a needle safety element with improved stable structure. A frame can surround the needle safety element to provide added stiffening of the needle safety element. The frame can include stays extending laterally of the needle safety element. The needle safety element with the frame can be slidably located on a needle and in a catheter hub in a ready to use position and be removable from the catheter hub in a protective position.

Abstract: A catheter assembly includes a catheter hub having an elastomeric septum that divides the catheter hub into a distal chamber and a proximal chamber. The septum also includes at least one slit that is closed and sealed when the septum is in an at-rest state. A septum activator is proximal the septum. When an external force pushes the activator against the septum, the activator deforms the septum so as to break the seal and create a flow path through the septum. A portion of the septum activator can be collapsible when subjected to the outside force. When the outside force is removed, the collapsible portion springs back to its at-rest shape, helping to pull the activator out of deforming engagement with the septum so that the septum can reseal. The activator can also be spring-biased away from engagement with the septum so that when the outside force is removed, the spring urges the activator out of engagement with the septum. With the activator removed, the septum slit can reseal.

Abstract: A catheter assembly includes a catheter adapter and an introducer needle. The introducer needle extends through the catheter adapter and through a catheter tube so as to assist placement of the catheter tube into a patient's blood vessel. Blood flashback into the catheter tube and/or catheter adapter through an aperture in a side of the needle indicates when the catheter tube is within the blood vessel. After the catheter tube is placed in the blood vessel, the introducer needle is withdrawn. A primary septum within the catheter adapter blocks blood flow in a proximal direction past the primary septum. A secondary septum proximal the primary septum is biased so as to enter into the aperture in the introducer needle and plug the aperture while the needle is being withdrawn, thus blocking blood flow through the aperture after the aperture is drawn through the primary septum.
