  • Patent number: 11478610
    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.

  • Patent number: 11457927
    Abstract: A microcatheter for delivering embolic agent to a vascular site is provided. The microcatheter has a biocompatible or biocompatible and biodegradable tip which can be detachably engaged to the microcatheter body by a thermoplastic sleeve. Once the embolic agent is delivered to the desired vascular site, the tip of the microcatheter is often entrapped within the mass of the liquid embolic fluid. Using the microcatheter, the clinician can retract the microcatheter at a predetermined retraction force thereby disengaging the tip from the microcatheter body allowing for easier removal of the microcatheter.

  • Patent number: 11446479
    Abstract: A medical device cap that protectively surrounds a medical device component for disinfection purposes and includes an identification element that can record and transmit pertinent information of the medical device cap and the medical device component is disclosed. The medical device cap enables documentation of instances when the cap is used and promotes stronger compliance with the use of medical device caps for applications involving disinfection of a medical device component such as an IV access port or a luer tip. Use of the medical device cap results in better compliance and monitoring of the use of such caps and leads to reduced incidence of CRBSI infections related to medical device component contamination. In one embodiment, the medical device cap enables automated real-time electronic documentation of when the cap is applied, while also documenting duration of application and tracking of device for inventory management.

  • Patent number: 9855192
    Abstract: An adapter for connection with a fluid container includes an outer housing having a distal end, a proximal end, and a generally cylindrical sidewall extending between the distal end and the proximal end, an inner member comprising a body rotatably inserted within the outer housing, a first locking arrangement configured to restrict the inner member from rotating relative to the housing in a first direction, and a second locking arrangement configured to restrict the inner member from rotating relative to the housing in both the first direction and a second direction. The adapter is transitionable between: a disengaged state, in which the first locking arrangement and the second locking arrangement are not engaged with the inner member; a partially engaged state in which the first locking arrangement engages the inner member; and a fully engaged state in which the second locking arrangement engages the inner member.

  • Patent number: 9017295
    Abstract: A syringe adapter with a ball-typed valve has a base, a dosing tube mounted around the base and a resilient valve mounted in the base and the dosing tube. The base has a guiding groove and an inner liquid channel communicating with each other, as well as an exhaust channel. Liquid medicine injected into the syringe adapter flows through the guiding groove and causes the inner liquid channel to be injected into a patient's body. The liquid medicine remaining in the split is cleaned when cleaning fluid is injected to clean the syringe adapter. Air in the syringe adapter flows out through the exhaust channel and is not injected into the patient's body, so the patient is free from pain. Furthermore, elements and assembling processes of the syringe adapter are simplified and manufacturing cost of the syringe adapter is lowered.

  • Patent number: 8973622
    Abstract: Some embodiments disclosed herein related to a device for transferring precise amounts of fluid from at least one source container to a at least one target container. In some embodiments, the fluid is first transferred from the source container (e.g., a vial) through a connector to an intermediate measuring container (e.g., a syringe). In some embodiments air can pass through an air inlet and enter the vial to compensate for the volume of fluid withdrawn from the vial. An air check valve or a bag or a filter can prevent the fluid from escaping through the air inlet. The precisely measured amount of fluid can then be transferred from the intermediate measuring container to the target container (e.g., an IV bag). In some embodiments the connector can include a source check valve and a target check valve to direct fluid first from the source container to the intermediate measuring container and then from the intermediate measuring container to the target container.

  • Patent number: 8974425
    Abstract: A male member (1) includes a tubular member (10) and a cover (20) covering at least a tip (11) of the tubular member. A lateral hole (14) that communicates with a flow path (13) is formed in an outer peripheral surface of the tubular member. The cover includes an outer peripheral wall (21) that can be deformed elastically by compression and a head part (23) that is provided at one end of the outer peripheral wall. The head part includes an interior cavity (24) into which the tubular member is inserted, and a slit (25) is formed in an innermost part (24a) of the interior cavity. In a state where the outer peripheral wall is not deformed by compression, an inner peripheral surface of the interior cavity contacts closely with the outer peripheral surface of the tubular member so as to block the lateral hole, and the tip of the tubular member and the innermost part of the interior cavity are spaced apart from each other.
