Negative pressure wound therapy tubing adapter

Negative pressure wound therapy tubing connector

A system for delivering reduced pressure and irrigation fluid to a wound site. The system includes a primary pressure source for delivering reduced pressure through a first lumen, a secondary pressure source for delivering secondary pressure through a second lumen, and an irrigation fluid source. A valve system is operable to selectively couple the secondary pressure source to the second lumen for delivering the secondary pressure to a wound site and selectively couple the fluid source to the second lumen for delivering the irrigation fluid to the wound site.

Negative pressure wound therapy instillation system

A canister connection system for a negative pressure wound therapy system. The canister connection system includes an attachment fixture removably connected to a pump unit. The attachment fixture includes a first engaging mechanism disposed adjacent its first end configured to engage a corresponding first engaging mechanism of the canister and a second engaging mechanism disposed adjacent its second end for engaging a corresponding second engaging mechanism of the canister for removably connecting the canister to the pump unit.

Negative pressure wound therapy canister connection system

A bridge for facilitating delivery of reduced pressure to a wound site of a patient includes a reduced pressure lumen configured to be fluidly coupled to a reduced pressure source, and a secondary pressure lumen configured to be fluidly coupled to a secondary pressure source at a first end and to the reduced pressure lumen at a second end, thereby facilitating flow of exudate removed from the wound site by the reduced pressure source using the secondary pressure source. The reduced pressure lumen or the secondary pressure lumen includes a skin contacting surface formed of a moisture permeable membrane comprising an air-impermeable film that allows moisture from the patient to transfer into the reduced pressure lumen or secondary pressure lumen through the moisture permeable membrane while maintaining reduced pressure at the wound site.

Multi-lumen bridge for negative pressure wound therapy system

A negative pressure wound therapy system treats multiple wounds on a patient's body. The system includes a source of negative air pressure, an air source, first and second fluid collection volumes, first and second wound-covering domes disposed over first and second wounds, a valve assembly disposed between the source of negative air pressure and the first and second fluid collection volumes, and between the air source and the first and second domes. The valve assembly has first and second operational modes. In the first, the valve assembly puts the source of negative air pressure in fluid communication with the first fluid collection volume, and the air source in fluid communication with the first dome. In the second, the valve assembly puts the source of negative air pressure in fluid communication with the second fluid collection volume, and the air source in fluid communication with the second dome.

Multiple-wound negative pressure wound therapy using multiple fluid collection volumes

A negative pressure wound therapy device that includes a first tubing connectable in flow communication with a source of negative pressure configured for application of negative pressure to a wound site, a second tubing in flow communication with the wound site, and a valve.

Connector with valve for negative pressure wound therapy system

A bridge for facilitating delivery of reduced pressure to a wound site includes a reduced pressure lumen configured to be fluidly coupled to a reduced pressure source, a secondary pressure lumen configured to be fluidly coupled to a secondary pressure source, and one or more fluid adapters operable to be connected to a wound dressing disposed at the wound site. The one or more fluid adapters are positioned and configured with respect to the reduced pressure lumen to apply reduced pressure from the reduced pressure lumen to the wound site through the wound dressing and deliver exudate removed from the wound site through the reduced pressure lumen to the reduced pressure tubing. The secondary pressure lumen is fluidly coupled to the reduced pressure lumen to facilitate flow of the exudate removed from the wound site by the reduced pressure source using the secondary pressure source.

A negative pressure wound therapy system is configured for treating multiple wounds on a patient's body. The system preferably includes a source of negative air pressure, an air source, a first fluid collection volume, and a second fluid collection volume. The source of negative air pressure is in fluid communication with the first fluid collection volume, the first collection volume is in fluid communication with the second fluid collection volume, and the second fluid collection volume is in fluid communication with the air source, so that the source of negative air pressure, the first fluid collection volume, the second fluid collection volume, and the air source are fluidly connected in series.
