A medical functional device with a valve seat for a check valve wherein the check valve is embodied such that it takes, in addition to a first position which is suitable for gas sterilization, a second, functional position, by means of applying force onto a section of the check valve or by means of moving or shifting the section, in which the check valve adopts a check or non-return function, wherein the check valve is embodied such that it remains in the second position after release or shortfall of the force or the moving effect following an accomplished transfer into the second position.

A fluid transfer connector comprises a medical standard connector part comprising a fluid transfer port, a connector part for flexible tubing, the connector part arranged to form a fluid connection with the fluid transfer port such that, in use, a fluid flow can pass between flexible tubing connected to the connector part and the fluid transfer port. The connector further comprises a moveable member arranged to interrupt the fluid flow in the flexible tubing when moved from a first position to a second position. The moveable member is further arranged to release a connection, in use, between the medical standard connector part and a corresponding adaptor part such as a female hub.

A gastrointestinal balloon system includes a gastrointestinal balloon and a check valve located within the gastrointestinal balloon. The check valve is configured to allow fluid flow into and out of the gastrointestinal balloon. The check valve includes a string coupled to the check valve, the string having a loop on a proximal end and a catheter having a lumen. The lumen is configured to receive a grasping tool. The grasping tool extends out a distal end of the catheter for grabbing the loop to align the catheter with the check valve. Also, a check valve, two-wat valve, and method of using the same in a gastrointestinal balloon.

Provided is a medication dispenser configured to discharge a liquid state medication stored therein by a pumping operation in a predetermined amount in a drop state and prevent a noise occurrence during medication discharge, and having a bacteria infiltration prevention function, wherein a flow path member and a second check valve are mounted in a liner, the second check valve is composed of a hemispherical cylinder mounted in an elevation space of the liner, having an open upper part, and of which a diameter decreases toward a lower end and includes a variable part in which the hemispherical cylinder is vertically variable and an opening and closing protrusion configured to perform supply and blocking of a flow path.

An apparatus for preventing backflow. The apparatus includes a housing; a trap flow part forming a flow passage for a medical fluid, a discharge part provided on an lower portion of the housing and to receive the medical fluid from the trap flow part and to discharge the medical fluid; a backflow prevention chamber part provided between the trap flow part and the discharge part; and a plate-shaped backflow prevention member provided on one surface of the inner side of the backflow prevention chamber part connected to the trap flow part and in close contact with a periphery of the outlet opening, the plate-shaped backflow prevention member being provided to open or close the opening depending on forward flow and the backflow of the medical fluid.

A valve includes a body including an inner bore extending between a first port and a second port, a seat, and one or more restrainers and a disk that is moveable between the seat and the one or more restrainers such that a first pressure that is less than 1 pascal and applied in a first direction causes the disk to move from a first position towards a second position to permit fluid communication between the first port and the second port. A metamaterial scaffold including a structure defining a lumen, at least a portion of an outer or non-lumen surface of the structure is coated with a plurality of biological cells, and wherein the structure is composed of a metamaterial.

A storage container having a base storage compartment configured to receive a divider by which the storage compartment is divided into two or more sub-compartments, wherein divider includes a tool configured to provide a secondary utility or function unrelated to dividing the storage compartment.

The present disclosure provides a medical connector for enteral applications. The medical connector includes a body portion having a distal patient access fitting and a proximal fluid delivery device fitting as well as an administration port. The administration port for administrating or extracting fluids or medicine includes a cylindrical cavity, an administration port seal having a normally-closed slit, a plunger, a plunger sleeve, and a compression member. Engaging a non-luer female tip with the administration port actuates the compression member such that the plunger pierces the normally-closed slit, causing it to open allowing fluid communication with the body portion.

An improved aerosol dispensing apparatus includes an aerosol container, a discharge piece movably mounted to the aerosol container, a flow control valve mounted within the discharge piece, a battery, and an electronically controlled metering valve electronically connected to the battery and in fluid communication with the flow control valve. The flow control valve is movable between an open position wherein a volume of an aerosol formulation is directed from the aerosol container through the flow control valve to the metering valve, and a closed position, wherein the metering valve is configured to precisely control a flow of the aerosol formulation outward of the discharge piece. A solenoid is electronically connected to the battery and is movable between an actuated position wherein the solenoid urges the flow control valve into the open position, and an un-actuated position wherein the flow control valve remains in the closed position.

A valve includes a body including an inner bore extending between a first port and a second port, a seat, and one or more restrainers and a disk that is moveable between the seat and the one or more restrainers such that a first pressure that is less than 1 pascal and applied in a first direction causes the disk to move from a first position towards a second position to permit fluid communication between the first port and the second port. A metamaterial scaffold including a structure defining a lumen, at least a portion of an outer or non-lumen surface of the structure is coated with a plurality of biological cells, and wherein the structure is composed of a metamaterial.
