Wound therapy system with humidifier
A wound therapy device includes a wound dressing and a humidifier configured to deliver humid air to a wound site to which the wound dressing is applied. The humidifier may be a remote structure that is fluidly connected to the wound dressing applied about a patient's skin at a wound site. Alternatively, the humidified may be integrated with the wound dressing to define an integral, portable therapy device that may be worn by the patient. The wound therapy device may be a standalone wound treatment device, or may be used in conjunction with other wound treatment devices, such as, e.g., negative pressure wound therapy devices.
1. A wound therapy device, comprising:
a wound dressing; and
a humidifier configured to be disposed between a backing layer of the wound dressing and a wound site to which the wound dressing is applied;
a sensor configured to detect humidity at the wound site; and
wherein the humidifier is further configured to deliver humid air to the wound site.
2. The wound therapy device of claim 1 , further comprising a controller configured to control operation of the humidifier.
3. The wound therapy device of claim 2 , wherein the controller is configured to control operation of the humidifier in response to the humidity at the wound site detected by the sensing element.
4. The wound therapy device of claim 3 , wherein the controller is configured to operate the humidifier in response to the sensing element detecting a degree of humidity at the wound site that is below a predetermined threshold.
5. The wound therapy device of claim 1 , wherein the humidifier includes a fluid reservoir.
6. The wound therapy device of claim 5 , wherein two or more different fluids are provided within the fluid reservoir.
7. The wound therapy device of claim 5 , wherein the humidifier further includes a moisture generating element.
8. The wound therapy device of claim 7 , wherein the moisture generating element includes a heater.
9. The wound therapy device of claim 7 , wherein the moisture generating element includes a piezoelectric transducer.
10. The wound therapy device of claim 7 , wherein the moisture generating element includes a wick.
11. The wound therapy device of claim 7 , wherein the moisture generating element includes an impeller.
12. The wound therapy device of claim 7 , wherein the moisture generating element includes a heat moisture exchanger.
13. The wound therapy device of claim 7 , wherein moisture generating element includes an active heat and moisture exchanger.
14. The wound therapy device of claim 7 , wherein moisture generating element includes a hygroscopic heat and moisture exchanger.
15. The wound therapy device of claim 7 , wherein moisture generating element includes an atomizer.
16. The wound therapy device of claim 1 , further comprising a fluid tube extending between and fluidly connecting the humidifier and the wound dressing, wherein one or both of an interior of the fluid tube and an exterior of the fluid tube is insulated to prevent condensation.
17. The wound therapy device of claim 1 , further comprising a fluid tube extending between and fluidly connecting the humidifier and the wound dressing, wherein one or both of an interior of the fluid tube and an exterior of the fluid tube is coated with an anti-condensate material.
18. The wound therapy device of claim 1 , wherein the dressing comprises:
a foam pad configured to be disposed at the wound site;
a backing layer configured to be disposed over the foam pad and sealed to skin surrounding the wound site; and
a scaffold structure configured to be supported by the foam pad and spaced apart from the wound site, the scaffold structure further configured to condense moisture at the wound site.
