Some embodiments disclosed herein relate to a medical connector having a backflow resistance module configured to prevent fluid from being drawn into the connector when a backflow inducing event occurs. In some embodiments, the backflow resistance module can include a variable-volume chamber configured to change in volume in response to a backflow-inducing event and a check valve configured to resist backflow. In some embodiments, the medical connector can include a fluid diverter configured to direct fluid flowing through the medical connector into the variable volume chamber to prevent fluid stagnation therein. In some embodiments, the medical connector includes a body member, a base member, a seal member, a support member, and a valve member.

Some embodiments disclosed herein relate to medical connectors with a housing comprising a proximal body member and a base member that form an internal cavity with a proximal abutment surface. A seal member and a rigid, hollow elongated portion are located within the internal cavity such that a proximal tip of the elongated member extends proximally within the internal cavity further than the abutment surface.

Some embodiments disclosed herein relate to medical connectors with a housing comprising a proximal body member and a base member that form an internal cavity with a proximal abutment surface. An elastomeric seal without a guide member is positioned within the internal cavity. A rigid, hollow elongated portion is located within the internal cavity such that in an open configuration, a tip of the elongated portion is more proximal than a proximal surface of the elastomeric seal. A distal portion of the elastomeric seal is seated radially within a region surrounded by a plurality of longitudinally extending protrusions.

An apparatus for producing gas for use in medical applications. The apparatus includes a compressed gas unit having at least one container of compressed gas and a solenoid valve. An adjustable pressure regulator communicably connected to the gas container, separate and distinct from the solenoid valve, is adjusted to control the pressure of the gas provided from the container to tire solenoid valve An electrical power source Is connected to the solenoid valve. A pressure activated electronic switch connected to the power source is responsive to a selected amount of voluntary fingertip, pressure for opening the solenoid valve to transmit the gas therethrough to a conduit, which further transmits the gas to a destination for use or storage.

A breaker device for acting onto a closure element (40) of a medical tubing (4) comprises: a drive arrangement (2) having a drive device (20), a drive element (23) driven by the drive device (20) and at least one locking element (22A, 22B), and a breaker module (3) which is arrangeable on the drive arrangement (2). The breaker module (3) comprises a housing (30), a movable part (31) movably arranged on the housing (30), a breaking element (315) for acting onto the closure element (40) of the tubing (4) and a locking mechanism (32A, 32B). The breaker module (3) in an attached state is placed on the drive arrangement (2) and is locked to the drive arrangement (2) via the locking mechanism (32A, 32B) engaging with the at least one locking element (22A, 22B), the drive element (23) being in operative connection with the movable part (31) in the attached state such that a movement of the drive element (23) causes the movable part (31) to move for actuating the breaking element (315). The breaker module (3) is releasable from the drive arrangement (2) by disengaging the locking mechanism (32A, 32B) from the at least one locking element (22A, 22B). Herein, the locking mechanism comprises at least one actuation member (32A, 32B) which is displaceable between a first position and a second position with respect to the housing (30), wherein the at least one actuation member (32A, 32B) is constituted to act, in the first position, onto the movable part (31) to force the movable part (31) into a position in which the movable part (31) can be brought into operative connection with the drive element (20) when arranging the breaker module (3) on the drive arrangement (2), and to engage, in the second position, with the at least one locking element (22A, 22B) of the drive arrangement (2) when the breaker module (3) is in the attached state.

A syringe adapter is provided. The adapter includes a housing having a first end and a second end positioned opposite the first end. The housing may include a first portion and a second portion connected to the first portion. The first end of the housing can include a connector configured to be secured to a syringe barrel. The adapter also includes a cannula positioned within the housing and a seal arrangement including a membrane positioned within the housing and movable within the housing. The first portion of the housing can be connected to the second portion via axial and radial interference between the first portion and the second portion of the housing.
