A positive pressure airway device for providing resistance in an air pathway for a patient exhaling. The device includes a central tube region, a inspiratory air passageway for passing air into the central tube region when a patient breathing through the device inhales, and an expiratory air passageway for passing air out of the central tube region when a patient breathing through the device exhales, A valve in the expiratory air passageway allows air to flow out only when a patient using the device exhales with an expiratory air pressure greater than a selected pressure, and includes a stopper and a coil spring with an interior portion that is free from any structure that would inhibit the “side-to-side” movement of the spring within the housing. The stopper has a cone-shaped air-stopping surface providing a valve angle that is different from the valve-seat angle so that either laminar or oscillating flow may be obtained.

A suction/irrigation medical device comprises a valve body having one or more conduits fluidically coupled thereto and a first channel extending through the valve body. The medical device also comprises a first valve plunger disposed along the first channel and configured to move along an axis to open and close the first channel. The first valve plunger has a first opening to permit a fluid to flow through the first channel. The medical device also comprises a second valve plunger disposed along the first channel and along a second channel to couple the second channel into the first channel when the second valve plunger is in a first position. The second valve plunger has a second opening that has at least one dimension that is greater than a corresponding dimension of the first opening of the first valve plunger.

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.

A collection device and a collection process provide the capability of receiving secretions, which have been suctioned out of a patient (P). A collecting unit including a bag (3) and a cover (2) encloses a collecting unit interior space (In1). The suctioned secretions flow through a patient-side fluid connection and through a patient-side port (4) in the cover into the collecting unit interior space. A backflow barrier includes a blocking body, which is fastened to a surface of the cover of the collecting unit interior space. In a blocking state, the blocking body closes the patient-side port. A restoring force generator exerts a restoring force on the blocking body, to hold the backflow barrier in the blocking state. A flow of secretions through the patient-side port into the collecting unit interior space brings about a transference of the backflow barrier into a flow stat e against the restoring force.

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.

Embodiments disclosed herein are directed to a connector for a fluid drainage system for fluidly coupling a catheter to a drainage tube. The connector includes a body defining a drainage lumen extending along a longitudinal axis from a distal portion to a proximal portion. The connector also includes a positive air pressure inlet and a valve slidably engaged with a valve housing along the longitudinal axis between a first position and a second position. The valve in the first position provides fluid communication between the distal portion and the proximal portion of the drainage lumen, and the valve in the second position occludes fluid communication between the proximal portion and the distal portion of the drainage lumen. Pressurized air provided at the inlet can transition the valve to the second position and clear any dependent loops within the drainage lumen.

A connector for coupling a container carrying a medical fluid to a vascular access device may include a housing comprising and inner surface defining an internal chamber comprising a fluid channel disposed in the internal chamber. The fluid channel may include a pair of oppositely positioned cutouts. The connector may further include a slider disposed and supported in the internal chamber and having an internal compartment and an aperture through inner walls of the internal compartment. The slider may be reciprocally movable between (i) a first position, where the aperture of the slider is axially aligned with the pair of cutouts to allow the medical fluid to flow through the outlet, and (ii) a second position where the aperture of the slider is not aligned with the pair of cutouts and the inner walls of the slider blocks fluid connection between the slider and the fluid channel.

A flow control device may include a housing having a primary valve body defining a primary inlet and an outlet of the flow control device, a secondary valve body defining a secondary inlet of the flow control device, and a chamber defined by an inner circumferential surface of the housing. The primary and secondary inlets may share a common central axis, and a central axis of the outlet may be perpendicularly disposed relative to the common central axis. The chamber may extend between the primary and secondary valve bodies for fluidly connecting the primary and secondary inlets with the outlet. The flow control device may further include a valve member reciprocally mounted in the chamber to (i) block fluid communication between the secondary inlet and the outlet when fluid pressure into the primary inlet is higher than fluid pressure into the secondary inlet, and (ii) block fluid communication between the primary inlet and the outlet when fluid pressure into the secondary inlet is higher than fluid pressure into the primary inlet.

A flow control device includes a housing having a primary inlet, a secondary inlet, and an outlet disposed downstream of the primary and secondary inlets. The flow control device further includes a chamber defined by an inner circumferential surface of the housing. The chamber fluidly connects the primary and secondary inlets with the outlet. A valve member is mounted in the chamber to pivot toward and block the primary inlet by fluid pressure in the secondary inlet when fluid pressure into the secondary inlet is higher than fluid pressure into the primary inlet.
