  • MULTIPLE-USE INTRAVENOUS CATHETER ASSEMBLY SEPTUM AND SEPTUM ACTUATOR
    Publication number: 20170333676
    Abstract: The present invention relates to a multiple-use intravenous (IV) catheter assembly septum and septum actuator. In particular, the present invention relates to an IV catheter assembly having a stationary septum actuator and a blood control septum, wherein the blood control septum is configured to slide within a catheter adapter of the IV catheter assembly between a compressed state and an uncompressed state. When in the compressed state, a slit of the blood control septum is opened and the septum comprises stored compressive potential energy. When the septum is released from the compressed state, the stored compressive potential energy is release and the blood control septum is restored to its original shape, thereby closing the septum's slit.

  • BLOOD CONTROL CATHETER VALVE EMPLOYING ACTUATOR WITH FLEXIBLE RETENTION ARMS
    Publication number: 20170128712
    Abstract: The present invention extends to a blood control catheter valve for use in a catheter adapter. The blood control catheter value employs an actuator for bypassing a septum to open the blood control catheter valve. The actuator includes flexible retention arms positioned on one end which retract into the body of the actuator while the end of the actuator passes through the septum, and then expand outwardly to maintain the actuator positioned within the septum. This design facilitates the manufacturing of catheter adapters (as well as blood control catheter valves and other components that attach to the catheter adapter) because the design can reduce the tolerance requirements of such components. Further, the design provides a reliable blood control catheter valve that does not require the catheter adapter to be increased in size to accommodate the valve.

  • Blood control IV catheter with antimicrobial properties
    Patent number: 9579486
    Abstract: A medical device is presented, which includes a fluid pathway and a septum slidably housed within the fluid pathway. The septum can be opened by a septum actuator disposed in a fixed position within the fluid pathway. In some examples, both the septum actuator and the septum have at least one surface exposed to the fluid pathway. An anti-pathogenic material can be applied to these surfaces.

  • IV FLOW MANAGEMENT SYSTEMS AND METHODS
    Publication number: 20160287785
    Abstract: An intravenous delivery system may operate by gravity feed, and may have a liquid source containing a liquid, a drip unit that receives the liquid from the liquid source, and tubing that receives the liquid from the drip unit for delivery to a patient. A flow rate sensor may be used to measure a flow rate of liquid through the intravenous delivery system, and may generate a flow rate signal indicative of the flow rate. A controller may receive the signal, and may compare the flow rate with a desired flow rate. If the flow rate is more or less than the desired flow rate, the controller may transmit a control signal to a flow rate regulator. The flow rate regulator may receive the control signal and, in response, modify the flow rate to bring the flow rate closer to the desired flow rate.
