Subatmospheric pressure mechanism for wound therapy system
View Patent ↗A portable system for subatmospheric pressure therapy in connection with healing a surgical wound is provided. The system includes a wound dressing dimensioned for positioning relative to a wound bed of a subject, and a collection canister in fluid communication with the wound dressing. The canister includes a base defining a fluid receiving cavity and having a fluid inlet port and a vacuum port. The fluid inlet port is configured for fluid communication with a wound dressing. The system further includes a cover selectively engageable to the base, e.g., in a snap-fit manner. The cover is configured to receive a control unit and has a vent assembly for exhausting the control unit. A seal member is interposed relative to the base and the cover to establish and maintain a substantial sealed relationship between the two components when assembled.
1. A portable system for subatmospheric pressure therapy in connection with healing a surgical wound, which comprises:
a wound dressing dimensioned for positioning relative to a wound bed of a subject; and
a collection canister in fluid communication with the wound dressing, the canister including:
a base defining a fluid receiving cavity and having a fluid inlet port and a vacuum port, the fluid inlet port being configured for fluid communication with the wound dressing;
a cover selectively engageable to the base, the cover having a control unit and a vent for exhausting the control unit;
a divider having a plurality of longitudinal grooves formed on an underside thereof; and
a seal member interposed relative to the base and the cover, the seal member adapted to establish a substantial sealed relation between the base and the cover.
2. The system according to claim 1 wherein the control unit includes a vacuum source and a power source.
3. The system according to claim 1 wherein including a hydrophobic membrane covering the vacuum port.
4. The system according to claim 1 wherein the seal member comprises a gel.
5. The system according to claim 1 wherein the vent is recessed relative to the cover.
6. The system according to claim 1 wherein the divider further includes a channel fluidly communicating the plurality of longitudinal grooves with at least one of the fluid inlet port and the vacuum port.
7. The system according to claim 1 including a cap positionable within at least one of the fluid inlet port and the vacuum port.
