摘要： Systems, methods, and connectors are provided that introduce a working gas at certain times into a reduced-pressure dressing into order to break or avoid vacuum locks in the conduits removing fluids. In one instance, a reduced-pressure connector includes a connector body for applying a reduced pressure to the tissue site. The connector body is formed with a venting port, a body conduit, and a receptacle to receive a reduced-pressure delivery conduit. The reduced-pressure connector includes a flexible member coupled to the connector body over the venting port. The flexible member is formed with at least one venting aperture. The flexible member is biased away from the venting port and is configured to collapse and seal the venting port under a reduced pressure greater than a threshold pressure. Other systems, apparatuses, and methods are disclosed.

摘要： A siphon guard includes a housing having an inlet and an outlet. A primary flow path is disposed within the housing and is in fluid communication with the inlet and the outlet. A secondary flow path is disposed within the housing and is in fluid communication with the inlet and the outlet. The secondary flow path has a higher resistance to fluid flow than the primary path. A valve is disposed within the primary flow path. The valve has a valve seat and a first ball and a second ball. The first ball is movable by gravity between a valve closed position, where the first ball is in contact with the valve seat, and a valve open position, where the first ball is spaced from the valve seat. The first ball is disposed between the second ball and the valve seat. The second ball is movable by gravity between a valve closed position and a valve opened position.

摘要： An oxygen mixing valve comprises a valve body. The valve body has an oxygen inlet, an air inlet, and a gas mixture outlet. A mixing chamber in communication with the gas mixture outlet, an oxygen chamber in communication with the oxygen inlet, and an air chamber in communication with the air inlet are disposed in the valve body. A first guide seat is elastically disposed in the oxygen chamber, and a second guide seat is elastically disposed in the air chamber. A first ball and a second ball are respectively disposed at inner ends of the first guide seat and the second guide seat. The first ball and the second ball are connected through a ball mandril. A mandril is movably disposed at an outer end of the first guide seat, a bearing capable of rotating is disposed at an outer side of the mandril, an involute cam is disposed at an outer side of the bearing, and the involute camis connected to an output shaft of a stepper motor. The oxygen mixing valve has advantages of simple structure, convenient mounting and maintenance, low manufacturing cost, capability of sensitively and precisely adjusting the ratio of the oxygen to air, and capability of controlling the tidal volume in conjunction with a common proportional valve.

摘要： The fluid delivery system includes a pressurizing device for delivering a pressurized injection fluid, a low pressure fluid delivery system, and a pressure isolation mechanism adapted for fluid communication with the pressurizing device and low pressure fluid delivery system. The pressure isolation mechanism includes a housing defining an inlet port, an isolation port, and an internal cavity. The housing defines a seal seat in the internal cavity between the inlet port and isolation port. A valve member is disposed in the internal cavity. The valve member is free floating in the internal cavity and is adapted to engage the seal seat. The valve member has an open position permitting fluid communication between the inlet port and isolation port, and is fluid flow responsive to fluid flow in the inlet port to engage the seal seat and attain a closed position preventing fluid flow between the inlet port and isolation port.

摘要： Disclosed herein is a fluid infusion device of the type that delivers medication fluid to the body of a patient. The device includes or cooperates with a fluid reservoir, and the device has a sealing assembly to receive and form a fluid seal with the fluid reservoir. A retractable sealing element surrounding a hollow fluid delivery needle may be used to seal a port of the fluid reservoir. The port may include a pressure vent that is sealed by the retractable sealing element. In one variation, the reservoir includes a moving valve sleeve that holds a septum. The septum moves to allow the reservoir to vent, and to form a seal with the port when the needle pierces the septum. In another variation, the device includes a needleless sealing assembly. In yet other variations, the device uses a needled fluid reservoir.

摘要： A valve assembly for use with a catheter assembly is provided. The valve assembly includes a valve housing defining a longitudinal axis and adapted for fluid engagement with a catheter assembly. The valve housing has an internal passageway for flow of fluids relative to the catheter assembly. A valve member is at least partially disposed within the valve housing and defines a valve passage. The valve member is adapted for movement within the valve housing between an open position wherein the valve passage is in general alignment with the internal passageway of the valve housing to permit flow of fluids through the valve housing, and a closed position to substantially occlude the internal passageway of the valve housing. An actuation mechanism is selectively movable in a general longitudinal direction to cause corresponding movement of the valve member between the open position and the closed position.
