A hand-free arthroscopic outflow control device (100) having a body (10) featuring a multi port valve body comprising a sleeve (50) fitted with a piston (40) actuated by a pedal (30), the sleeve (50) communicating with a surgical site inflow port (52), a surgical theatre inflow port (54) and an outflow port (56) disposed between these respective inflow ports (52,54), so that the piston (40) can be positioned alternatively to vent the outflow port (56) under suction by drawing from one only of the surgical site inflow port (52) and the surgical theatre inflow port (54).

A fluid flow controller includes a first body portion defining a receiving surface, a second body portion, and a fluid transfer device. The second body portion includes a controller engagement member, and is configured to couple to the first body portion such that the controller engagement member faces and is spaced from an engagement point of the receiving surface. The controller engagement member is configured to be adjusted from a first distance to a second distance closer to the engagement point than the first distance based on a force applied by a foot pedal apparatus. The fluid transfer device defines a flow channel configured to be adjusted from defining a first cross sectional area to a second, lesser cross sectional area while the controller engagement member is in contact with the first fluid transfer device and adjusted towards the second distance in response to the applied force.

A respiratory device includes a blower having an inlet and an outlet, a patient interface, and a valve including a valve member that is rotatable through a first angular displacement in a first direction from a first position to a second position. The outlet of the blower is coupled to the patient interface so that positive pressure is provided to a patient's airway via the patient interface when the valve member is in the first position. The inlet of the blower is coupled to the patient interface so that negative pressure is provided to the patient's airway via the patient interface when the valve member is in the second position. The valve member is rotatably oscillated back and forth when the valve member is in the first position and when the valve member is in the second position so that oscillations in the positive pressure and negative pressure, respectively, are provided to the patient's airway.

A manually operable pump for the effective removal of fluids to include blood, blood clots, fluid, and air from a body cavity of a subject is provided. The manually operable pump is adapted to be connect to a range of fluid conduits and is equipped with one-way valves that effectively permit flow of fluid through the pump in only one direction. The sensitivity of the one-way valves is such that when properly positioned, fluid can flow through the valves and out of the pump without manual compression of the pump and with the aid of gravity power alone.

A reduced pressure treatment system includes a compressible chamber positionable beneath a foot of a user and being movable between an expanded position and a compressed position. The compressible chamber includes an inlet and an outlet. An inlet valve is in fluid communication with the inlet to prevent fluid within the compressible chamber from exiting the inlet, and an outlet valve is in fluid communication with the outlet to prevent fluid from entering the compressible chamber through the outlet. A biasing member is disposed within the compressible chamber to bias the compressible chamber toward the expanded position, and a manifold is positionable at a tissue site and in fluid communication with the inlet of the compressible chamber.

A system and method for actuating controlled stimulation of a patient in a confined medical position helps sooth and entertain a patient receiving medical treatment while resting on a support member, like a dental chair. The system provides a support member, and integrates at least one air actuated animated member, such as a mobile or figurine, proximal to the support member, to enable animated motion by the animated member through pressurized air. Pressurized air causes the animated members to articulate in animated, colorful movements. Audio signals are also generated by the animated member in response to the pressurized air. The animated member can be a mobile or a cartoon character with joints, axes, and limbs that move when engaged by pressurized air. The patient or caregiver control distribution of the pressurized air by manipulating a foot valve and an arm valve to control the animated members.

A pressure regulating or pressure relief device comprises an inlet and an outlet chamber with an outlet. The inlet is in fluid communication with the outlet chamber. A valve seat is located between the inlet and the outlet. A valve member is biased to seal against the valve seat, and displaces from the valve seat by an inlet pressure at the inlet increasing above a pressure threshold to allow a flow of gases from the inlet to the outlet via the outlet chamber. The flow of gases through the outlet causes an outlet pressure in the outlet chamber to act on the valve member together with the inlet pressure to displace the valve member from the valve seat.

A respiratory therapy apparatus is operable to deliver multiple types of therapy to a patient. The apparatus includes a main housing and a nebulizer tray that selectively attaches to a bottom of the main housing. The apparatus also includes a filter housing unit having an antenna surrounding a pneumatic passage and a transponder chip coupled to the antenna. The main housing also has an antenna that surrounds a respective pneumatic passage of a main outlet port of the apparatus. The main housing includes a reader that controls communication between the antennae. The main housing of the apparatus also has a pivotable hose support plate, a firmware upgrade port underneath part of the top wall of the housing, and a graphical user interface (GUI) that displays various user inputs for control of the apparatus and that displays various alert conditions that are detected.

The outlet of the blower is coupled to the patient interface so that positive pressure is provided to a patient's airway via the patient interface when the valve member is in the first position. The inlet of the blower is coupled to the patient interface so that negative pressure is provided to the patient's airway via the patient interface when the valve member is in the second position. The valve member is rotatably oscillated back and forth when the valve member is in the first position and when the valve member is in the second position so that oscillations in the positive pressure and negative pressure, respectively, are provided to the patient's airway.
