Wound management
View Patent ↗A method and apparatus are disclosed for delivering at least one agent to a wound site. The method includes the steps of providing a delivery tube having an outlet at a wound site, covering the wound site with a drape and introducing agent at an agent inlet port of the delivery tube. The agent passes along the delivery tube through the drape to the wound site. The agent can be a wide variety or mixture of fluids such as but not limited to pain relief medicament, anti-biotics, saline solution and/or hydrating fluid.
1. Apparatus for delivering at least one agent to a wound site, comprising:
a drape for covering a wound site;
a negative pressure source;
an aspiration conduit configured to fluidically connect the negative pressure source to the drape; and
a delivery tube comprising a substantially T-shaped portion, comprising an outlet, an agent inlet port and a gas inlet port, wherein the gas inlet port is positioned upstream of the agent inlet port;
wherein the gas inlet port further comprises an air filter; and
wherein the drape is configured to maintain negative pressure provided from the negative pressure source at the wound site and the gas inlet port is configured to allow gas to flush the agent inlet port, flush the delivery tube, and to fill the wound when the wound site is maintained under negative pressure.
2. The apparatus according to claim 1 , further comprising:
an inlet valve downstream of the agent inlet port and a self sealing septum on the agent inlet port.
3. The apparatus according to claim 1 , further comprising:
a releasable cap connected to the gas inlet port.
4. The apparatus according to claim 1 , further comprising:
a syringe connectable to the agent inlet port.
5. The apparatus according to claim 1 , further comprising:
a reservoir having an outlet orifice connectable to the agent inlet port, wherein the reservoir comprises a mechanical or electrical time release system.
6. The apparatus according to claim 1 , further comprising:
the drape comprises a preformed aperture arranged to receive and seal against a portion of the delivery tube.
7. The apparatus according to claim 1 , further comprising:
a disc-like body portion extending outwardly around an outlet region of the delivery tube.
8. The apparatus according to claim 7 , further comprising:
a penetrating portion extending from a lower surface of the disk-like body portion.
9. The apparatus according to claim 1 , further comprising: a drain locatable under the drape at the wound site.
10. The apparatus according to claim 9 , wherein the aspiration conduit is connectable to the drain and the negative pressure source is an aspiration pump connectable to a proximal end of the aspiration conduit, and further comprising a filler for packing into the wound site.
11. The apparatus according to claim 1 , wherein the substantially T-shaped portion of the delivery tube is a T-shaped portion.
