Apparatus for the provision of topical negative pressure therapy
View Patent ↗Apparatus for the provision of topical negative pressure therapy to a user is described, the apparatus comprising a device and a waste canister connected thereto, the waste 5 canister being operably connected for receiving wound exudate to a wound dressing by an aspiration conduit which is releasably connected to the dressing, wherein the waste canister has a blank connector portion thereon for sealably receiving a disconnected dressing end of the aspiration conduit.
1. An apparatus for the provision of topical negative pressure therapy to a wound on a user, the apparatus comprising:
a device for providing a source of negative pressure to the wound;
a waste canister connected thereto;
an aspiration conduit connectable with the waste canister and the dressing and configured to communicate negative pressure from the device to the dressing; and
a blank connector portion supported by the waste canister for sealably receiving a disconnected dressing end of the aspiration conduit, the blank connector being sealed to prevent passage of waste fluids into and out of the waste canister.
2. An apparatus according to claim 1 , wherein the waste canister comprises at least one plastics material moulding.
3. An apparatus according to claim 2 , wherein the blank connector portion is integrally moulded with the waste canister.
4. An apparatus according claim 2 , wherein the blank connector portion is affixed to the waste canister.
5. An apparatus according to claim 1 , wherein the blank connector portion is one of a male or a female connector portion and a connector portion on a dressing end of the aspiration conduit is the other of a male or a female connector portion.
6. An apparatus according to claim 5 , wherein the blank connector portion and the connector portion on the dressing end of the aspiration conduit have mutual sealing means.
7. An apparatus according to claim 6 , wherein the sealing means comprises an “O” ring seal.
8. An apparatus according to claim 6 , wherein the sealing means comprises mutually tapered surfaces.
9. An apparatus according to claim 8 , wherein the connector portions are provided with co-operating screw threaded portions.
10. An apparatus according to claim 1 , the canister having integral filters in an outlet path thereof.
11. An apparatus according to claim 1 , wherein the device for providing a source of negative pressure to the wound comprises a control system configured to trigger alarm means when an abnormal condition in the apparatus is encountered.
12. An apparatus according to claim 1 , wherein the blank connector is configured such that there is no through path from the connector portion to the interior of the waste canister.
13. A method of using the waste canister of claim 1 , comprising:
disconnecting the dressing end of the aspiration conduit from the dressing; and
connecting the dressing end of the aspiration conduit to the blank connector portion supported by the waste canister to secure the dressing end of the aspiration conduit and to prevent any substances within the aspiration conduit from flowing out of the dressing end of the aspiration conduit.
14. An apparatus for the provision of topical negative pressure therapy to a wound on a user, the apparatus comprising:
a negative pressure device for providing a source of negative pressure to the wound;
a waste canister connected thereto;
an aspiration conduit connectable with the waste canister and the dressing and configured to communicate negative pressure from the device to the dressing; and
a blank connector portion supported by the negative pressure device for sealably receiving a disconnected dressing end of the aspiration conduit, the blank connector being sealed to prevent passage of waste fluids into and out of the disconnected dressing end of the aspiration conduit.
15. An apparatus according to claim 14 , wherein the blank connector portion is integrally moulded with the negative pressure device.
16. An apparatus according claim 14 , wherein the blank connector portion is affixed to the negative pressure device.
17. An apparatus according to claim 14 , wherein the blank connector portion is one of a male or a female connector portion and a connector portion on a dressing end of the aspiration conduit is the other of a male or a female connector portion.
18. An apparatus according to claim 17 , wherein the blank connector portion and the connector portion on the dressing end of the aspiration conduit have at least one of an “O” ring seal, mutually tapered surfaces, and co-operating screw threaded portions.
19. A method of using the waste canister of claim 14 , comprising:
disconnecting the dressing end of the aspiration conduit from the dressing; and
connecting the dressing end of the aspiration conduit to the blank connector portion supported by the negative pressure device to secure the dressing end of the aspiration conduit and to prevent any substances within the aspiration conduit from flowing out of the disconnected dressing end of the aspiration conduit.
