This disclosure relates generally to the treatment of wounds and infections, and particularly to systems and devices for immersion-therapy treatment of wounds and infections in humans and animals. Uses for these systems and devices may include, but are not limited to: treating wounds and infections, or promoting healthier hygiene, on or around the feet, toes, ankles, hands, fingers, knees, arms, and elbows (and equivalents); aerating, agitating, and slowing the cooling of a liquid in a basin to aid the blood-flow, debridement, and medication of a wound or infection on a body part submersed therein; and mixing heated air into a liquid for the above purposes.
In the field of treatment of wounds and infections and promoting healthier hygiene, some wounds and infections are treated by irrigation therapy that may include medicated water or an aqueous saline solution. For example, some wounds and infections are treated by immersion in a warm liquid—such as water, medicated water, or an aqueous saline solution. To aid the blood-flow, debridement, and medication of a wound or infection, it is desirable to aerate, agitate, and slow the cooling of the warm liquid.
One problem with current systems and devices designed for foot bath irrigation is that the liquid cools too quickly and does not stay at a desired temperature for long enough. Current systems and devices that actively heat the liquid are also not power-efficient. Yet another problem with whirlpool systems designed for wound care therapy is that the devices are large, not portable, and are shared by multiple patients despite being difficult or impossible to fully sanitize between uses. Furthermore, these devices are not designed for home therapy and increase the cost of healthcare while decreasing the quality of life and convenience for the patients.
Accordingly, there remains a need in the art for improved systems and methods for maintaining a desired temperature of a liquid by efficiently slowing the cooling of the liquid and for increasing the hygienicity, portability, efficiency, and safety of treating wounds and infections.
The present disclosure describes wound- and infection-care bath systems and devices. Systems, devices, and methods for treating wounds and infections by immersion therapy are provided along with methods for the use thereof. The systems and devices may include a basin and a heater-blower apparatus. The systems and devices aerate, agitate, and slow the cooling of a liquid in the basin to aid the blood-flow, debridement, and medication of a wound or infection.

The heater-blower apparatus 14 has an intake pipe 18, a heating-element 19, an impeller-assembly 20, and an output pipe 21. The heater-blower apparatus 14—specifically the impeller-assembly 20—moves air: first, into and through the intake pipe 18; then, across the heating-element 19; and finally, through and out of the output pipe 21.
The intake pipe 18 may be any suitable pipe and may be integral with the heater-blower housing 15. In

The heater-blower housing 15 contains the impeller-assembly 20 and the heating element 19, protecting a user from potential mechanical, electrical, and thermal dangers of by the heater-blower apparatus 14. The heater-blower housing 15 couples the intake pipe 18 and the output pipe 21 to the impeller-assembly 20, so that the impeller-assembly 20 can move air both: into and through the intake pipe 18; and through and out of the output pipe 19.
The heater-blower apparatus 14 is sized, shaped, and powered to create an air pressure at the output pipe 21 of between 1.0 pounds per square inch gauge (“psig”) and 11 psig, preferably between 2.0 psig and 10. psig, and more preferably between 3.0 psig and 9.0 psig.
A switch 22 (shown in
The bottom-cover 23 is molded with cover-fittings 46 that allow the attachment to the bottom surface 12 of the basin 1 (described above). (Not every cover-fitting 46 is marked with a reference numeral on
In some embodiments, the output pipe 21 is coupled to the air-channel 4, 5 by a rigid or flexible tubing (e.g., a plastic or rubber hose). Adapters 47 connect the flexible tubing to the air-channel 4, 5 or output-pipe hole 6, 7. Adapters 47 secure the flexible tubing by threads, barbs, friction, adhesive, or any other suitable method. The adapters 47 shown in
In some embodiments, the aeration irrigates and continuously provides a mixing action to mix water with any medication and to deliver the medication topically to the site of a wound or infection. In some embodiments, the aeration serves as a mechanism for blunt debridement, for increased blood-circulation at the site of the wound or infection, and/or for increased hygiene.
The switch 22 in in the system 25 of
As illustrated, the system 29 also includes two stoppers 31, 32. As shown in
When the desired depth of liquid is in the basin 1, when the liquid is at a desired warmth, and when the heater-blower apparatus 14 is on, then the system 25 maintain the desired warmth of the liquid for a desired duration. For example, the desired warmth of the liquid may be a temperature between 40 degrees Celsius and 30 degrees Celsius (preferably between 40 degrees Celsius and 35 degrees Celsius), and the desired duration may be between 10 minutes and 20 minutes (preferably 15 minutes). Then the system 25 would maintain liquid in the basin 1 at a temperature between 40 degrees Celsius and 35 degrees Celsius for at least 15 minutes. The system 25 accomplishes that by the heater-blower apparatus 14 adding heat to the liquid at a rate equal to or less than the rate at which the liquid loses heat to the system's 25 environment. In some embodiments, the rate of heat-transfer is approximately 20 watts.
In some embodiments, the system 25 further comprises a temperature-indicator (not shown) that indicates the warmth of the liquid so that a user can know whether the liquid is too warm, not warm enough, or at the desired warmth. In such embodiments, this is advantageous to users with neuropathy or numbness in the body part by preventing burns.
The heating-element 19 is a resistor that produces heat when an electrical current flows through the heating-element 19. The power-consumption and the voltage-drop of the heating-element 19 both allows the heating element 19 to generate sufficient heat—for example, sufficient heat to maintain a desired warmth of the liquid—and provides a power-loss or voltage-drop of a sufficient amount (e.g., a voltage-drop of between 80 volts and 90 volts) to allow the impeller-assembly 20 to operate safely. In some embodiments, the voltage-divider behavior of the heating-element 19 enables a low-voltage impeller-assembly 20 to operate in an approximately 110-120-volt AC (or equivalent) environment without additional components such as a voltage-regulator or power-supply unit.
The heating element 19, located inside the heater-blower apparatus 14, is connected to a rectifier circuit 36 that rectifies AC to direct-current (“DC”) as required by the impeller-assembly 20. A DC-powered impeller-assembly 20 may be preferred, due to the larger size of AC-powered fans.
In step 38, a user puts into the basin 1 a liquid with the desired warmth in the amount necessary to fill the basin 1 to a desired depth of liquid in the basin 1. In step 39, a user puts a body part into the basin 1 and submerges the body part in the liquid. In step 40, a user engages the switch 22 to turn on the heater-blower apparatus 14. In step 41, the impeller-assembly 20 moves air into the intake pipe 18 to the heating-element 19. In step 42, the heating-element heats the air. In step 43, the impeller-assembly 20 moves the heated air out through an output pipe 21 into an air-channel 4, 5. In step 43, the heated air moves through the nozzle-holes 28 into the liquid. In step 44, some of the heat of the heated air is transferred to the liquid. In step 45, after a desired duration, the user disengages the switch 22 to turn off the heater-blower apparatus.
While the foregoing specification has described specific embodiments of this invention and many details have been put forth for the purpose of illustration or example, it will be apparent to one skilled in the art that the invention is susceptible to additional embodiments and that certain of the details described herein can be varied considerably without departing from the basic principles of the invention.
