Disclosed is a tube connector for medical treatment including a housing including an internal channel configured to allow an inflow pipe disposed at the front end thereof and an outflow pipe disposed at the rear end thereof to fluidly communicate with each other, an insertion hole formed from the outer surface of the rear end of the housing to the internal channel, and at least one branch pipe disposed so as to fluidly communicate with the internal channel, a push button having a through hole, the push button being disposed in the insertion hole so as to be movable upwards and downwards, and an elastically deformable dome-shaped balloon configured to surround the insertion hole of the housing, the lower part of the balloon being open, wherein the internal channel of the housing is opened and closed through the upward and downward movement of the push button.

A dilution spacer for a metered-dose inhaler comprises an enclosure defining a dilution chamber. An ambient air inlet and an outlet are in fluid communication with the dilution chamber. The ambient air inlet is positioned opposite the outlet whereby suction through the outlet from outside the enclosure draws ambient air into the enclosure through the ambient air inlet to generate an airflow path from the ambient air inlet through the dilution chamber and out of the outlet. The dilution spacer may include an actuator inlet configured to securely releasably interengage a metered-dose inhaler actuator mouthpiece, or may include a receptacle having an actuator nozzle and configured to receive a metered-dose inhaler canister, A metered-dose inhaler plume entering the dilution chamber intersects the airflow path thereto and airflow along the airflow path entrains and redirects at least a portion of the metered-dose inhaler plume toward the outlet.

Disclosed herein is a vertical-flat-arrangement-type suction and irrigation device which is easy to operate. The vertical-flat-arrangement-type suction and irrigation device includes a housing, a probe, and a suction and supply unit. The housing include a front chamber and a rear chamber spaced apart from each other and connected via a connection duct, a first duct connected to a front of the front chamber and extending forwards, a second duct connected to a rear of the front chamber and extending rearwards, and a third duct connected to a rear of the rear chamber and extending rearwards. The suction and supply unit includes a supply valve reciprocally moved inside the front chamber in an axial direction of the front chamber and a suction valve reciprocally moved inside the rear chamber in an axial direction of the rear chamber.

A flow restriction device may include a proximal housing including an internal fluid channel, a distal housing including an internal fluid channel, and an intermediate housing interposed between the proximal and distal housings. The intermediate housing may include an internal chamber, and a slider reciprocally disposed in the internal chamber. The slider may include an internal fluid channel and a seal overlaying an outer surface of slider excluding the fluid channel, and may be reciprocally movable between (i) a first position where the internal fluid channel of the slider is axially aligned with the internal fluid channels of the proximal and distal housings to allow a fluid to flow therethrough, and (ii) a second position where the internal fluid channel of the slider is not aligned with the internal fluid channels of the proximal and distal housings and the seal blocks fluid connection between the proximal and distal housings.

A medicinal infusion system includes a safety valve for isolating residual medication by providing a single point of fluidic disconnect to encapsulate a residual fluid volume prone to spillage. The safety valve couples a medicinal repository such as an infusion pump to a medicinal supply, typically from a syringe or tubing. The safety valve includes a resilient, deformable, or hinged surface for isolating and sealing the medicinal flow to eliminate and/or isolate any residual volume in tubing and connectors. The isolating surface accommodates an inserted fitting or coupling for allowing the medicinal flow to fill the infusion pump. Upon disconnection, fluids on either side of the safety valve are therefore isolated on the respective fill or source sides, and residual volume prone to spillage is eliminated.

A check valve for high flow medical gas applications is disclosed. The check valve includes a valve body that defines a flow channel through the valve body from an inlet to an outlet. A movable plunger is in the flow channel of the valve body, with the plunger being constrained in the flow channel between the inlet and the outlet. The plunger comprises a finned frustoconical inlet end a finned frustoconical tip at its outlet which act as flow directing elements which reduce inlet and outlet turbulence at higher medical gas pressures by reducing the gas flow turbulence within the flow channel.

An enteral feeding apparatus comprises a pod having an expansile pouch which defines a reservoir for enteral fluid and a gas impermeable barrier surrounding the pouch. The pod has an inlet port for delivery of enteral fluid into the pouch and an outlet port having a seal which is pierceable to release enteral fluid from the pouch for delivery to a PEG via a feeding line. The expansile pouch provides the sole force by which enteral fluid is delivered from the pouch through a regulator. The system can accommodate a range of enteral fluids with a wide range of viscosities.

A needle-free connector assembly is provided that includes a main housing coupled to an indicator housing. A plunger is coupled to a bellows disposed in the main housing. An inlet port is disposed at an upstream end of the indicator housing and an outlet port is disposed at a downstream end of the main housing, with a valve disposed within the indicator housing and adjacent the inlet port. A switch member is slidingly disposed in the main housing, wherein the needle-free connector assembly provides both flow regulation and pressure indication when the switch member is in a downstream position and only pressure indication when the switch member is in an upstream position. Infusion sets and methods of operating a needle-free connector are also provided.

A connector for connecting a container containing a medical fluid to a vascular access device may include an upper housing defining a first internal chamber, and a lower housing coupled to the upper housing and defining a second internal chamber for circulation of the medical fluid into the outlet. The connector may further include a slider disposed at least partially in the first and second internal chambers, and a plug coupled to a distal end of the slider. The slider may be reciprocally movable between (i) an open position, where the plug is spaced apart from a floor of the internal chamber to allow the medical fluid to flow through the outlet, and (ii) a closed position where the plug abuts the floor of the second internal chamber to block the medical fluid from flowing through the outlet.
