Abstract

A therapy device for instillation of fluid to a tissue site is described. The therapy device includes a base having a cartridge receptacle and a support coupled to the base to secure the base to a pole. The therapy device also includes a cartridge configured to engage the base when positioned in the cartridge receptacle. The therapy device also includes a pump head disposed within the cartridge receptacle and configured to engage the cartridge for movement of fluid. The cartridge includes a body forming at least a portion of a fluid reservoir and a tube segment coupled to the body and in fluid communication with the fluid reservoir. The tube segment is configured to engage the pump head.

Claims

1. A therapy device for instillation of fluid to a tissue site, the therapy device comprising:

a base having a cartridge receptacle configured to receive a cartridge;

the cartridge separable from the base and configured to engage the base when positioned in the cartridge receptacle, the cartridge comprising;

a body having a raceway recessed therein, wherein the body and the raceway form at least a portion of a fluid reservoir,

a tube segment coupled to the body and having a tube suspended across the raceway, the tube in fluid communication with the fluid reservoir; and

a pump head having a roller and at least one lobe, the pump head disposed within the cartridge receptacle and configured to engage the tube for movement of fluid.

2. The therapy device of claim 1, further comprising a fill port fluidly coupled to the fluid reservoir and configured to receive fluid.

3. The therapy device of claim 1, further comprising a fill port fluidly coupled to the fluid reservoir and configured to receive fluid;

and

a heat seal coupled to the fill port.

4. The therapy device of claim 1, further comprising:

a load cell segment fluidly coupled to the tube segment between an end of the tube segment and the fluid reservoir; and

a sensor coupled to the base and configured to communicatively couple to the load cell segment if the cartridge is disposed in the cartridge receptacle.

5. The therapy device of claim 1, further comprising:

an ultra-sonic inspection segment fluidly coupled to the tube segment between an end of the tube segment and the tissue site; and

a sensor coupled to the base and configured to communicatively couple to the ultra-sonic inspection segment if the cartridge is disposed in the cartridge receptacle.

6. The therapy device of claim 1, wherein the body comprises a lid configured to form at least a portion of the fluid reservoir.

7. The therapy device of claim 1, wherein the body comprises a lid configured to form at least a portion of the fluid reservoir, the raceway is in the lid, and the raceway is configured to receive at least a portion of the tube segment and the pump head.

8. The therapy device of claim 1, wherein the body has an ovoid-shape with a rounded end and a flattened end opposite the rounded end.

9. The therapy device of claim 1, wherein the body has an ovoid-shape with a rounded end and a flattened end opposite the rounded end, the body having at least one notch proximate to the flattened end.

10. The therapy device of claim 1, wherein the raceway comprises a semicircular raceway.

11. The therapy device of claim 1, further comprising an interactive panel coupled to the base and operatively coupled to the pump head for operation thereof.

12. A therapy device for treating a tissue site, the therapy device comprising:

a solution cartridge separable from the therapy device and comprising a fluid reservoir, a raceway forming at least a portion of the fluid reservoir, and a tube suspended across the raceway;

a cartridge receptacle formed in the therapy device and adapted to receive the solution cartridge; and

a rotary-delivery pump head disposed within the cartridge receptacle, the rotary-delivery pump head having a circumferential edge and lobes coupled to the circumferential edge;

wherein the circumferential edge is adapted to press the tube into the raceway and the lobes are adapted to cyclically engage the tube in the raceway.

13. The therapy device of claim 12, further comprising a dressing fluidly coupled to the tube.

14. The therapy device of claim 12, further comprising a reduced-pressure source and a dressing, wherein the dressing is fluidly coupled to the reduced-pressure source and the tube.

15. The therapy device of claim 12, further comprising a fill port fluidly coupled to the fluid reservoir and configured to receive fluid.

16. The therapy device of claim 12, further comprising a port fluidly coupling a bottom portion of the fluid reservoir to the tube.

17. The therapy device of claim 12, wherein the therapy device is configured to provide reduced pressure to the tissue site.
