DETAILED DESCRIPTION OF THE INVENTION

[0034] In order to meet these needs, the present invention discloses a hydrotherapy apparatus 100 for creating a vacuum-sealed inner chamber containing the wound area and permitting spiral-directional streams of fluid to irrigate the wound with a vacuum source to remove excess debris in a timely and sanitary manner.

[0035] FIGS. 1-5 illustrate an example hydrotherapy device 100 including a chamber 102 in which a vortex effect is created for treatment of a wound. The hydrotherapy device 100 includes a body 104 with an annular wall 106 integral with a base 108 defining the chamber 102 within. In other embodiments, the annular wall 106 is semi-spherical and does not include a base. In some embodiments, the annular wall 106 has a thickness T1 of about 10 mm, although the thickness T1 for each of the annular wall 106 may vary as desired or necessitated by manufacturing. Similarly, the thickness of the base 108 may be varied as desired. During use, an edge or rim 110 of the annular wall 106 is positioned so that the wound is enclosed within the chamber 102 of the device 100. While the illustrated embodiment has a cup shape, the hydrotherapy device 100 may have any other shape or size as desired.

[0036] Fluid enters the chamber 102 through a plurality of openings 112 spaced along an inner surface 114 of the annular wall 106 adjacent the rim 110 as shown in FIGS. 2 and 3. Referring to FIG. 3, a void 116 is formed along the surface area of the wall 106 within the thickness T1 of the body 104 between an inner portion 104a and an outer portion 104b. The void 116 is in fluid communication with a first port 118 positioned on an outer surface 120 of the base 108. A plurality of channels 117 extends between a terminal channel 116a of the void 116 and the plurality of openings 112. Input tubing (not shown) connected to a fluid source is secured to the input port 118 during use of the hydrotherapy device 100 on a user. During use, fluid enters the hydrotherapy device 100 through the first port 118, travels through the void 116 and the plurality of channels 117 and their respective openings 118, and into the chamber 102.

[0037] Referring to FIG. 4, the respective channel 117 forms an angle at each opening 112 along the inner surface 114 of the annular wall 106 on a plane parallel to the base 108 of the hydrotherapy device 100 or to the surface 119 of the patient's body. As shown in FIG. 5, the respective channel 117 also meets the inner surface 114 at an angle of on a plane transverse to the base 108 or along a plane perpendicular to the surface 119 of the patient's body. The combined angles and direct the fluid so that it enters the chamber 102 in a spiral pattern. Angles and may be varied as required by the flow and size requirements or as desired. In a preferred embodiment, each of the angles and is at least 45 degrees. The diameter of the openings 112 may vary depending on the amount of suction used and other design requirements or preferences. In one embodiment, each opening 112 may be about 1 to about 3 mm in diameter.

[0038] Referring to FIGS. 1-3, output port 122 in the base 108 extends through the thickness T2 of the body 104 between the outer and inner surfaces 120, 124 of the base 108. During use, second tubing (not shown) connected to a vacuum source is secured to the output port 122. In some embodiments, the second tubing is sized to be positioned within the second port 122 through the base 120 and directly into the chamber, sealing off the void 116. In other embodiments, the hydrotherapy device 100 includes an internal tube 123 within the second port 122 and through the base 120 in order to seal off the void 116. With the vacuum source activated, the suction pulls fluid from the fluid source through the first port 118 and into the chamber 102 of the hydrotherapy device 100. The suction also creates a seal between the rim 110 of the annular wall 106 and the surface of the user's skin around the wound. The use of the vacuum source prevents fluid from escaping underneath the rim 110 of the body 104 and prohibits the sliding of the hydrotherapy device 100 away from the wound site.

[0039] The fluid may be a purified and sterile water, although any suitable fluid for wound care may be utilized in the present invention. The hydrotherapy device may also be used for the delivery of pharmaceutical agents, oxygen, and other materials to a wound site. For example, the fluid used for treatment may be a perfluorocarbon material, such as Fluosol-DA, that can deliver oxygen to the tissues and reduce bacterial content through high oxygen partial pressures. Antibiotics and other surface debridement agents, such as nonabsorbable microspheres that are capable of gently debriding tissues, can be added to the fluid prior to connection to the hydrotherapy device. Warming fluids and adding chemotherapeutic agents may provide more direct treatments for skin cancers, such as melanoma.

[0040] FIGS. 6-9 illustrate a further embodiment of a hydrotherapy device 200. The hydrotherapy device 200 has a boot-like shape for providing hydrotherapy to a wound on the calf and/or ankle of the patient. The body 201 includes a lateral section 202 and a medial section 204 joined together using any attachment means 206, such as hook and loop material, to create the boot-like shape. Each of the lateral and medial sections 202, 204 forms a half of the boot-like shape separated along the length of the foot as shown in FIG. 6, although other configurations may be used as desired. A watertight seal such as a neoprene gasket 208 may be applied to the edges of the lateral and medial sections 202, 204 in order to create the watertight seal. The hydrotherapy device 200 further includes a seal 210 along an opening 212 at an upper end 214 of the device 200 to enclose a chamber 216 within the lateral and medial sections 202, 204. The seal 210 may be made of a silicon, neoprene, or other suitable material.

[0041] Similar to the hydrotherapy device 100 of FIGS. 1-5, each of the lateral and medial walls 220, 222 of the lateral and medial sections 202, 204, respectively, includes an enclosed, internal void 218 extending along the surface area thereof. Each section 220, 222 includes a first port 224 extending fully through the wall 220, 222, and a second port 226 extends from the outer surface partially through the wall 220 or 222 and is in fluid communication with the respective void 218. In the illustrated embodiment, the first port 224 is located near the toe 226 of the hydrotherapy device 200 and is connected to a vacuum source via tubing. Similar to the hydrotherapy device 100, an internal tube 227 may be used within the first port 224 to seal of the void 218. The second port 226 is located near the upper end 214 of the hydrotherapy device 200 and is connected to a fluid source via tubing. In other embodiments, the void 218 may be continuous between sections 202, 204.

[0042] Referring to FIGS. 8 and 9, a plurality of channels 228 extend from the void 218 to inner surfaces 230, 232 of the lateral and medial sections 202, 204, respectively, forming an angle along a central axis of each channel 228 at the inner surface 230, 232 along a plane parallel to the bottom of the patient's foot. Each channel 228 also meets the inner surface 230, 232 at an angle of along a plane perpendicular to the bottom of the patient's foot. In one embodiment, each of the angles and is 45 degrees. The combined angles and direct the fluid so that it enters the chamber 216 in a spiral pattern or vortex motion. In some embodiments, the plurality of channels is provided in a spiral pattern, as shown in FIG. 7. In still further embodiments, the channels of the lateral and medial sections 202, 204 are coordinated so that the spiral pattern is a continuous pattern. Further, the angles and size of the channels may vary depending on the target part of the body.

[0043] As with the hydrotherapy device 100, tubing is used to connect the first port with a vacuum source and the second port with a fluid source. Activation of the vacuum source pulls fluid from the fluid source, through the second port, into the void, through the plurality of channels, and into the chamber of the device.

[0044] In the illustrated embodiment, the shape of the hydrotherapy device 100 approximates a dome or semi-circle, although any shape may used as desired. The dimensions of the hydrotherapy device 100 may be modified as needed. The material is preferably a flexible plastic that conforms to the surface of the body, such as, but not limited to, a silicone material.

[0045] It should be noted that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages.
