Medical fluid extension set systems are disclosed that can include a tubing anchor coupled to tubing and a fluid coupling device, and can be anchored to a patient to resist unintended separation of the tubing anchor or a catheter coupled to the tubing, from a patient, and to permit separation or disconnection of a fluid pathway between the tubing and another device coupled to thereto upon exceeding a pulling force on the fluid coupling device, and where disconnection includes separation of first and second valve assemblies such that a fluid pathway of the first and second valve assemblies is obstructed upon disconnection of the fluid coupling device.

A multi-use disinfecting cap and method for disinfection and protection of a needleless IV injection port. The disinfecting cap has an upper chamber which contains a sterilizing solution and a low chamber which connects to a needleless IV injection port. The fluid can be manipulated to flow between the two chambers. When in use the cap protects and disinfects a needleless IV injection port when exposed prior to injecting medication into the needleless port and continues to disinfect and protect prior for any subsequent exposures. The cap is re-usable and provides a clear indication of the disinfecting solution and a datable top surface. The multi-use disinfecting cap may be removably clipped to the IV tubing and is shaped to prevent accidental rolling away if dropped.

A system for precision liquid delivery includes a gas reservoir having a known volume. The system has a tightly load-coupled pneumatic driver (a “TLCP driver”) that is configured to receive input power to cause the TLCP driver to move gas into the gas reservoir to produce a gas drive pressure. A valve is configured to couple the gas reservoir with a fluid reservoir having an unknown volume. The valve is further configured to selectively isolate or pneumatically couple pressures in the gas reservoir and the fluid reservoir. A gas-fluid interface couples pressure in the fluid reservoir to pressure in a fluid path. The fluid path is configured so that the fluid drive pressure driving the liquid in the fluid path is substantially the same as the fluid reservoir pressure. The system also has a pressure sensor configured to detect pressure in the gas reservoir and/or the fluid reservoir.

A method of dispensing a therapeutic fluid from a line includes providing an inlet line connectable to an upstream fluid source. The inlet line is in downstream fluid communication with a pumping chamber. The pumping chamber has a pump outlet. The method also includes actuating a force application assembly so as to restrict retrograde flow of fluid through the inlet while pressurizing the pumping chamber to urge flow through the pump outlet. A corresponding system employs the method.

A flush device including: a first housing provided with a first flow path; a second housing provided with a second flow path, the second housing being coupled to the first housing; a flow control device including a protrusion and a through hole connecting the first flow path to the second flow path in fluid communication; and an elastic member provided around the base of the flow control device to seal off a space between the first and the second flow paths. The elastic member is deformed to further connect the first and second flow paths in fluid communication. The first housing has an inner periphery provided with fitting receiving portions each being fitted to each of the fitting projections of the protrusion. According to this structure, the flush device can discharge a chemical liquid at a flow rate close to a defined amount.

A fluid connector, including a fluid path portion having an integral cannula extending in a first direction from a interior surface, and a latching portion secured to the fluid path portion and having a pair of displaceable arms. Each arm includes a connector latch disposed at a first cantilevered end of the arm, and an activation lever disposed at an opposite cantilevered end of the arm and extending in a second direction, not parallel to the first direction. A portion of the activation lever includes a first lateral tactile feature aligned substantially parallel to the first direction to prevent forward slippage of the fluid connector from a user's grasp in the second direction, and a portion of the activation lever includes a lateral tactile feature aligned substantially parallel to the second direction to prevent slippage of the fluid connector from a user's grasp in the first direction.

The present invention relates to a device for measuring, recording, and acting in response to changes in air pressures encountered through the lumen of a connected needle. The device signals when it has been powered and signals when the device recognizes both pressures and pressure change rates indicative of synovial cavity joint penetration, such as knee joint penetration. Synovial cavity pressures detected and acted upon may either be supra- (positive) or sub-atmospheric (negative). Internal light emitting diodes and a laptop connected display are demonstrated as signaling and communication mechanisms. Methods for delivering medicaments into human and animal intra-articular cavities or joints such as synovial cavities are provided. Furthermore, methods for facilitating the diagnoses of joint effusion also are provided.

A device for supporting IV tubing along a distance and suspending the tubing above the floor includes a support arm and a cradle. The cradle is positioned along a shaft of the support and is configured to receive a length of IV tubing therein.

A modular connector assembly for a medical container may include a plurality of covers and a plurality of adapters. Each cover is connectable to a cooperatively dimensioned medical container. Each adapter is attachable in fluid sealing engagement with each cover by an interface assembly including a first interface segment formed on each of said plurality of covers and a second interface segment formed on each of said plurality of adapters. The first and second interface segments and corresponding ones of the covers and adapters are initially separable and subsequently connected to define a fluid sealing engagement between connected ones of the cover and adapter. The structural configuration of each of the plurality of adapters is variable to define a different one of a plurality of medical connector types.

Fluid connector systems including first and second valve assemblies couplable together to form a fluid pathway therethrough, and can resist fluid flow through the connector system when the valve assemblies are separated from each other, the first valve assembly including a compressible valve within a cavity and configured to surround a post forming a fluid passage, the compressible valve can resist fluid flow through the post in a first position and to reduce the resistance to fluid flow through the post in a second position, and the second valve assembly including a valve plug positioned within a bore and configured to obstruct a fluid passage, such that when the valve assemblies are coupled together the compressible valve is moved toward the second position and the post extends through the compressible valve and the valve plug to form the fluid pathway through the connector system.
