  • Publication number: 20200008898
    Abstract: Tissue access devices and methods of using the same are disclosed. The devices can have a sensor configured to occlude a flow path by deflecting a membrane into the flow path when the devices become dislodged from tissue. The sensor can be configured to partially or fully occlude the flow path. The sensor can have a spring. The spring can be biased to move the sensor from a sensor first configuration to a sensor second configuration when a force applied by the sensor first surface against a non-sensor surface changes from a first force to a second force less than the first force. The membrane can be deflected into the flow path when the sensor is in the sensor second configuration.

  • Patent number: 10512728
    Abstract: A filtered needle for use in administering a liquid payload, including a needle and connector portion and a filtering needle cap. The filtering needle cap including a distal open end in fluid communication via an internal channel with a proximal open end of the filtering needle cap. The filtering needle cap proximal end sized to receive the distal end of the hub within the proximal end of the filtering needle cap to reversibly engage the hub when needle distal end is inserted into the internal channel. The filtering needle cap including a filter element and a seal to seal around an outside diameter of the hollow needle so that liquid payload is drawn into the lumen in the hollow needle as liquid payload is filtered and drawn into the fluid fitting. The filtering needle cap is designed to limit a dead volume of liquid payload drawn into the filtering needle cap but not entering into the distal end of the hollow needle.

  • Publication number: 20190247570
    Abstract: Systems and methods of micro-infusion of medical fluids are disclosed. Micro-infusion systems may include a pump, a patient interface, tubing between the pump and the interface, and a micro-infusion device along the tubing. A first portion of the tubing above the micro-infusion device is longer than a second portion of the tubing below the device. The micro-infusion device may include a chamber in-line with the tubing, a first valve between the chamber and the first portion of the tubing, a second valve between the chamber and the second portion of the tubing and a third valve between the chamber and a dump chamber. The second valve may be slidably disposed within the chamber. A medical fluid may be provided into the chamber that slides the second valve displacing another fluid in the chamber through the third valve into the dump chamber.

  • Patent number: 10376639
    Abstract: Pump cassettes, infusion systems, and methods are described. An example infusion pump system may include a cassette recess with one or more valve actuators that extend through a surface of the cassette recess to operate a corresponding valve in a fluid passageway of a pump cassette mounted in the cassette recess. The valve actuator may include a base portion, a shaft extending from the base portion through the surface, and a spring disposed on the shaft and extending along a portion of the shaft. The spring may be disposed interior to the back surface. The system may include first and second valve actuators configured to operate corresponding first and second valves located on opposing sides of a pump chamber of the fluid passageway. A piston may be configured to cooperate with the first and second valve actuators to pump a fluid through the fluid passageway.

  • Publication number: 20150313796
    Abstract: In one aspect, the invention is directed to a port assembly for establishing fluid communication between a first container and a second container. The port assembly includes a retainer for connecting a first container, where the retainer is positioned in a cavity defined by a port housing that includes an axially fixed actuator. The housing also includes a plug member constructed to seal a fluid passageway between the port housing and an interior of a second container. The plug member is configured to move axially relative to the actuator. Rotation of the retainer relative to the actuator causes the plug member to move to an open position in which it does not seal a fluid passageway between the port housing and an interior of a second container. The rotation of the retainer relative to the port housing also causes the retainer to move axially relative to the port housing so that the actuator forces a stopper associated with a first container connected to the retainer into a first container.

  • Patent number: 8911421
    Abstract: A system for mixing the contents of a first container and a second container. The system includes the first container that has container body with an opening fluidly connected to a cavity defined by the container body, a first substance contained in the cavity, and a stopper sealing the opening. The second container includes a port assembly including a port housing connected to the second container and a retainer constructed to connect to the first container. The retainer is configured to rotate and move axially relative to the port housing, wherein relative rotation between the port housing and the retainer causes the retainer to move axially relative to the port housing. The port assembly further includes an axially fixed actuator constructed to force the stopper into the first container when the retainer is rotated relative to the port housing.

The port assembly includes a port housing for connection to a second container, and a retainer for connection to a first container, wherein the retainer rotates relative to the port housing and is constructed to move axially within the port housing. An actuator is axially fixed within the port housing and forces a stopper associated with a first container into a first container when the retainer moves axially within the port housing upon rotation of the retainer relative to the port housing. The assembly is configured to establish fluid communication between a first container and a second container upon rotation of the retainer relative to the port housing.
