A one-piece medical connector has a unitary body. The unitary body includes a rigid portion that forms a housing. The unitary body also includes a resilient portion located at least partially within the housing. At least a movable portion of the resilient portion is configured to move relative to the rigid portion. Movement of the resilient portion selectively permits fluid flow through the connector. The rigid portion and the resilient portion form a one-piece unitary connector.

Aspects include systems having an intravenous fluid bag, a tubing line assembly including tubing connected to a connector and a purge valve assembly including a spike and an outer housing. The outer housing is connected to the spike and includes a receiving end portion configured to receive the connector. The purge valve assembly further has a check valve provided within the outer housing. Generally, the purge valve assembly interconnects the fluid bag to the fluid tubing assembly for removal of air from the fluid bag prior to connection to the tubing line assembly. Various methods and purge valve assemblies provide a rapid infusion system for use. The purge valve assemblies do not require the user to reinsert the connector or spike into the intravenous fluid bag, creating a sterile solution to preparing the intravenous fluid for rapid infusion while reducing the risk of air emboli.

The invention relates to an automatic valve for regulating a flow rate of liquid intended to circulate in a flexible tube, comprising: a cam system (23) mounted moveably on a base and rotationally around an axis of rotation, a bearing part (24) translationally mounted on the base, arranged to be translationally moved as a result of a rotational movement of the cam system (23), and comprising a compression portion (240), an abutment part (25) positioned opposite the compression portion (240), defining with the bearing part (24) a receiving space intended to receive a flexible tube (3), the translation of the bearing part (24) displacing the compression portion (240) along the direction of translation, in order to modify a dimension of the receiving space, a magnet and a magnetic sensor detecting the magnetic field generated by the magnet.

Some fluid coupling devices described herein are configured for use in fluid systems for purposes of providing a repeatable, aseptic fluid coupling system. Such repeatable, aseptic fluid coupling systems are configured to facilitate multiple connection and disconnection cycles while repeatably establishing a sterile fluid pathway through the coupling system. The repeatable, aseptic fluid coupling systems can repeatably establish a sterile fluid pathway through the coupling system even though the coupling system may be used in a non-sterile environment.

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.

A drug delivery device includes a housing, a container disposed in the housing, an activation mechanism, a needle insertion mechanism, a fluid flow connection, and a valve in fluid communication with the fluid flow connection and the needle insertion mechanism. The container has an inner volume to contain a medicament which is urged out of the container by the activation mechanism. The needle insertion mechanism is adapted to insert a needle and/or a cannula to deliver the medicament from the container via the fluid flow connection. The valve is in fluid communication with the fluid flow connection and needle insertion mechanism, and is movable between first and second positions. Upon insertion of the needle and/or the cannula, the valve remains in the first position whereby fluid flow is restricted. At a later time, the valve is urged to the second position whereby fluid may flow through the needle or cannula.

Fluid communication devices and supporting structures may be provided for use with intraosseous devices. Apparatus and methods may also be provided to communicate fluids with an intraosseous device.
