Urinary incontinency, incontinence, or involuntary urination (collectively “UI”) is the involuntary leakage of urine from an individual's urinary tract. UI is a common and distressing problem, which may have a profound impact on the individual's quality of life. Several types of devices are available to individuals who experience UI to help them manage their individual situation. Due to the external nature of the male urethra and internal nature of the female urethra, incontinence devices are typically sex specific, with a majority of devices directed to the male penis due to ease of physical access. Example incontinence devices include collecting systems, absorbent products, fixer-occluder devices, indwelling catheters, and intermittent catheters.
Fixer-occluder devices (also referred to herein as “incontinence clamps”) are attached to the penis, compressing the urethra and surrounding penis to reduce or prevent the flow of urine there through. Existing incontinence clamps tend to be bulky, uncomfortable, rigid, and non-adjustable (or with limited adjustment). As a result, existing incontinence clamps tend to be effective only for light or moderate incontinence.
Implementations described and claimed herein address the foregoing problems by providing a user conformable incontinence clamp comprising: a first wire including a first selective attachment mechanism on a first end of the first wire; a second wire including a second selective attachment mechanism on a first end of the second wire; a flexible hinge connecting a second end of the first wire to a second end of the second wire; and a padded tube encompassing a majority of the clamp, wherein the first selective attachment mechanism is configured to selectively attach to the second selective attachment mechanism to close the clamp around a user's penis, and wherein the first wire and the second wire are selectively conformable to the user's penis.
Implementations described and claimed herein address the foregoing problems by further providing a method of using a user conformable incontinence clamp comprising: positioning the user conformable incontinence clamp at a desired location on a user's penis; closing the clamp around the user's penis; and compressing the clamp to conform to a desired shape and level of compression on the user's penis.
Other implementations are also described and recited herein.
User conformable incontinence clamps are disclosed herein that may address some or all of the aforementioned shortcomings identified in prior art incontinence clamps.
In operation, the clamp 102 is closed around a penis 108 by extending the penis 108 through the loop and attaching the first hook 104 to the second hook. A schematic cross-section of the penis 108 is shown, which includes a urethra 110. The urethra 110 is to be compressively closed by action of the clamp 102 as discussed with reference to
Opposing compressive forces 111, 113 are applied to the clamp 102, which exceed the yield strength of the underlying clamp material. As a result, the clamp 102 is plastically deformed in a manner that compresses the penis 108 and the urethra 110 as shown. Compression of the surrounding penis 102 compressively pinches the urethra 110, thereby reducing the cross-sectional area of the urethra 110. A rate at which urine may flow through the urethra 110 is proportionally reduced as the cross-sectional area is reduced. In various implementations, a user's thumbs and fingers apply the compressive forces 111, 113 and may vary the location, magnitude, and direction of the compressive forces 111, 113 from that shown in
Increasing opposing compressive forces 112, 114 are applied to the clamp 102 to provide additional plastic deformation of the clamp 102 and overcome any resistance to compression provided by the compressed penis 108 until the clamp 102 reaches the fully clamped position 115. When the clamp 102 reaches the fully clamped position 115, the user releases the compressive forces 112, 114 and the rigidity of the clamp 102 reduces or prevents deformation of the clamp 102 that would release the compressed penis 108.
In the fully clamped state, the urethra 110 is compressively pinched closed, thereby reducing the cross-sectional area of the urethra 110 to zero or near zero. Little to no urine is permitted to flow through the urethra 110 in the fully closed clamped position 115.
In various implementations, the opposing compressive forces 112, 114 of
Further, the opposing compressive forces 111, 113 of
Since the clamp 202 is primarily deformed at the bending node 220 when transitioning from the open position to the closed position, and vice versa, the wire cores 216, 218 can maintain their respective shapes even when the clamp 202 is opened and closed. This may reduce the opportunity for metal fatigue on the wire cores 216, 218 during repeated use of the clamp 202 and preserve user-selected shapes of the wire cores 216, 218 as the clamp 202 is opened and closed. Coated ends 222, 224 of the wire cores 216, 218 opposing the bending node 220 form structures for the user to physically manipulate the wire cores 216, 218, prevent the user from being poked with otherwise potentially sharp wire ends, and aid the wire cores 216, 218 selectively attaching together (see e.g.,
In various implementations, the wire cores 216, 218 are a solid metallic wires that are sufficiently flexible to be user conformable, but also sufficiently rigid to hold a selected shape in compression on the user's penis. More specifically, the wire cores 216, 218 may be made of platinum, silver, iron, copper, aluminum, gold, and various alloys thereof (e.g., brass, bronze, steel). The wire cores 216, 218 may also have any cross-sectional shape (e.g., circular, rectangular, etc.) and have a variety of gauges depending on material selection and desired rigidity of the wire cores 216, 218 (e.g., a copper alloy wire may be 10-14 gauge or approximately 12 gauge).
Wire core 216 is covered in insulation 226 and wire core 218 is covered in insulation 228. In various implementations, the insulation sections 226, 228 provide corrosion resistance to the wire cores 216, 218 and may be bonded to the wire cores 216, 218 such that the wire core/insulation combinations each deform as a single unit. In addition, an overall increased diameter and generally softer outer insulating material of the wire core/insulation combinations as compared to the wire cores 216, 218 alone may reduce or prevent the wire cores 216, 218 from cutting or otherwise damaging adjacent subsequent layers of the clamp 202 discussed below.
In various implementations, the insulation sections 226, 228 continuously wrap around the wire cores 216, 218, respectively. More specifically the insulation sections 226, 228 may be made of plastic, rubber-like polymers, and/or varnishes that cover or coat their respective wire cores 216, 218. The insulation sections 226, 228 may have any desired radial thickness depending on the desired protection afforded to the subsequent layers of the clamp 202. In some implementations, the wire core/insulation combinations are created from commercially available insulated electrical wire.
The wire core/insulation combinations are partially covered with a flexible tube 230, at least covering the bending node 220, creating a flexible hinge at the bending node 220. More specifically, axially aligned ends of each wire core/insulation combination meet at the bending node 220 and are covered by the flexible tube 230 and the flexible tube 230 extends a distance along each wire core/ insulation combination beyond the bending node 220. In various implementations, a small gap 221 is provided between the axially aligned ends of each wire core/insulation combination within the flexible tube 230 to prevent contact between the wire core/insulation combination as the flexible tube 230 is elastically deformed. As a result, the wire core/insulation combinations are attached together via the flexible tube 230 and the flexible tube 230 allows the clamp 202 to bend at the bending node 220 without substantial deformation of the individual wire core/insulation combinations. In various implementations, the wire core/insulation combinations are slip-fit, glued, welded, or otherwise securely attached to the flexible tube 230 so that the clamp 202 may be bent at the bending node 220 repeatedly without the connections between the wire core/insulation combinations and the flexible tube 230 slipping or breaking.
The flexible tube 230 is resilient, enabling the clamp 202 to readily bend at the bending node 220 repeatedly without failure. More specifically, the flexible tube 230 may be made of rubber (natural or synthetic) or plastic material. The flexible tube 230 extends any length along the individual wire core/insulation combinations sufficient to cover the bending node 220 and securely attach to the ends of the wire core/insulation combinations. In other implementations, another hinged structure (e.g., a metal hinge, spring-loaded hinge, etc.) is used in conjunction with or in lieu of the flexible tube 230.
The wire core/insulation/flexible tube combination is mostly covered in a padded tube 232 that covers the bending node 220 and a majority of the remaining length of the wire core/insulation/flexible tube combination. As a result, the padded tube 232 covers the portion of the clamp 202 intended to come in contact with the user's penis. The padded tube 232 may be loosely or securely attached to the wire core/insulation/flexible tube combination and increases the overall diameter of the clamp 202 to a level sufficient to provide comfort to the user, but still sufficiently small to be effective and not overly bulky in size. The padded tube 232 may stop short of covering the entire length of the clamp 202 so that the coated ends 222, 224 are exposed, allowing them to be used as hooks (see
The padded tube 232 is resilient, enabling the clamp 202 to readily bend at the bending node 220 without failure. More specifically, the flexible tube 230 may be made of rubber (natural or synthetic) foam or various textile materials. In various implementations, the padded tube 232 is made of a non-absorbent material to aid the user in maintaining the clamp 202 in a sanitary condition (i.e., making the clamp 202 easy to clean). In other implementations, the padded tube 232 is made of an absorbent material that can absorb blood, sweat, urine, or other bodily fluids and wick them away from the user's penis. Further, the padded tube 232 may be a variety of shapes (e.g., round or flat) and have a variety of surface textures (smooth, patterned, etc.).
In some implementations, the padded tube 232 is permanently affixed to the clamp 202 and the clamp 202 is replaced periodically. In other implementations, the padded tube 232 is made of a disposable material that is periodically removed and replaced by the user. For example, the padded tube 232 may have a seam (not shown) along its length that is selectively secured (e.g., via hook-and-loop tape or other selective fastener) to form the padded tube 232 around the wire core/insulation/flexible tube combination. The seam may then be oriented opposite a surface of the padded tube 232 that engages with the user's penis to prevent irritation caused by contact with the seam. The padded tube 232 may be replaced once the underlying material loses its resilience or to maintain a desired sanitary condition of the clamp 202. The padded tube 232 may have medication or lubricant embedded therein or coated thereon depending on the user's requirements in treating a specific medical condition or providing a comfortable fit. The padded tube 232 may also be made of an anti-microbial/bacterial/fungal substance or coated with the anti-microbial/bacterial/fungal substance to maintain the padded tube 232 in a sanitary condition and perhaps treat the user's specific medical condition (e.g., treating fungus or skin sores). Further yet, the padded tube 232 may include reactive reagents that upon application of urine, sweat, blood, or other bodily fluids provide evidence of the user's medical status to the user or the user's physician (e.g., blood sugar level, blood in urine, etc.).
In the depicted closed position, the coated ends 322, 324 of the solid wire cores 316, 318 opposing the bending node 320 are shown bent and partially hooked around one another to maintain the closed position. Further, the direction and magnitude that each solid wire core 316, 318 is bent may affect how the coated ends 322, 324 hook together. The user may vary the direction and magnitude that each solid wire cores 316, 318 is bent to achieve a desired fastening of the coated ends 322, 324 of the solid wire cores 316, 318 together. In other implementations, the clamp 302 incorporates other selective attachment mechanisms (e.g., hooks, snaps, magnets, buttons, etc.) at the ends of the solid wire cores 316, 318 opposing the bending node 320.
Overall dimensions of the clamp 302 may vary widely depending on user requirements. In some implementations, the clamp 302 has a standard size intended to fit all users. In other implementations, the clamp 302 comes in several discrete sizes that are selected based on an individual user's needs. For example, the clamp 302 may have a total outside length 334 ranging from 75 mm to 82 mm with a cross-sectional diameter 336 ranging from 10 mm to 13 mm. Further, the clamp 302 may have a total inside length 335 ranging from 50 mm to 75 mm.
A closing operation 415 closes the clamp around the user's penis. The user may elastically close the clamp by bending the clamp at the bending node, which brings the first and second ends of the clamp back in close proximity to one another. The user re-attaches the first and second selective attachment mechanisms located at the ends of the clamp to one another to form a continuous loop around the user's penis. Further, the closing operation 415 may be achieved solely with the user's hands, and in some cases only one of the user's hands. Still further, the opening operation 405, the positioning operation 410, and the closing operation 415 may be repeated with or without readjusting the clamp (see compression operation 420) so that the user may quickly open the clamp, urinate, and close the clamp without having to significantly readjust the clamp.
A compression operation 420 compresses the clamp against the user's penis. More specifically, the user applies compressive force on the clamp to plastically conform the clamp to a desired shape and level of compression on the user's penis to provide a desired level of UI protection and comfort for the user. Further, the compression operation 420 may be periodically repeated to adjust the compression on the user's penis to maintain the desired level of UI protection and comfort for the user.
In one example implementation, the user bends a lower portion of the clamp upward, which causes a hook at an end of the lower portion to spread outward. The user may bend the hook at the end of the lower portion inward to maintain attachment with a corresponding hook at an end of an upper portion of the clamp. To loosen the clamp, the user may bend the upper portion of the clamp upward and perhaps adjust one or both of the hooks. The lower portion of the clamp may then be straightened a bit to adjust the clamp to the user's comfort level. Finally, the upper portion may be bent again to achieve the desired level of protection and comfort to the user. These steps may be repeated iteratively and in various orders to achieve the intended performance of the clamp.
