DETAILED DESCRIPTION
An absorbent cleaning device may be used during a surgical procedure to clean gloves, medical appliances, and elongate medical devices. Some such surgical procedures may include, but are not limited to, vascular procedures and wire-based interventions. Such surgical procedures may be conducted in ambulatory care centers, catheterization laboratories, electrophysiology departments, hospitals, interventional suites, operating rooms, surgical centers, or other locations. During a surgical procedure, gloves, medical appliances, and elongate medical devices may become soiled by contact with bodily fluids (i.e., blood), tissue fragments, medical contrast media, and/or other matter.
An absorbent cleaning device may be configured to at least partially clean or remove such matter from gloves, medical appliances, and elongate medical devices. For example, during a catheterization a catheter may become at least partially coated with blood and/or other matter. An absorbent cleaning device may comprise an opening configured to accommodate and come into contact with a portion of the catheter such that upon agitation or movement of the catheter against the absorbent cleaning device the blood and/or other matter may be at least partially cleaned or removed from the catheter. In some embodiments, the opening may comprise a slit configured to accommodate a portion of a medical appliance or an elongate medical device. In other embodiments, the opening may comprise an elongate channel configured to accommodate a portion of a medical appliance or an elongate medical device. Furthermore, some absorbent cleaning devices may comprise a cleaning solution, a saline solution, and/or an anticoagulant (i.e., heparin). Still further, the absorbent cleaning device may comprise a substantially non-fibrous or non-particulate polymer. In certain embodiments, the polymers may or may not be cross-linked. In some examples, the absorbent cleaning device may comprise polyvinyl acetate, polyvinyl alcohol, or polyvinyl fluoride (PVF). In other examples, the absorbent cleaning device may comprise a hydrophilic cross-linked polymer including, but not limited to, polyhydroxyethylmethacrylate (pHEMA), a polyacrylate, a cross-linked polyacrylic acid, and a cross-linked polyamine derivative.
A body, such as the absorbent body of an absorbent cleaning device, may further be configured to secure or otherwise retain a portion of an elongate medical device or instrument during a therapy. For example, during a vascular intervention a practitioner may secure the relative position of a device such as a guide wire by disposing a portion of the guide wire in a slit disposed in the body. Interaction between the guide wire and opposing walls of the slit may then maintain the relative position of the guide wire with respect to the body. Thus, the body may be used to temporarily secure elongate instruments during therapy.
It will be readily understood by one of skill in the art having the benefit of this disclosure that the components of the embodiments, as generally described and illustrated in the figures herein, could be arranged and designed in a variety of configurations. Thus, the following more detailed description of various embodiments, as represented in the figures, is not intended to limit the scope of the disclosure, but is merely representative of various embodiments. While the various aspects of the embodiments are presented in drawings, the drawings are not necessarily drawn to scale unless specifically indicated.
The phrases “connected to,” “coupled to,” and “in communication with” refer to any form of interaction between two or more entities, including mechanical, electrical, magnetic, electromagnetic, fluid, and thermal interaction. Two components may be coupled to each other even though they are not in direct contact with each other. For example, two components may be coupled to each other through an intermediate component.
FIG. 1 is a perspective view of one embodiment of an absorbent cleaning device 100. The illustrated absorbent cleaning device 100 is substantially ovoid, prolate spheroid, or American-football shaped. It will be appreciated by one skilled in the art having the benefit of this disclosure that absorbent cleaning devices as described herein may comprise other shapes including, but not limited to, cones, cubes, cuboids, cylinders, dodecahedrons, octahedrons, prisms, pyramids, spheres, hemispheres, tetrahedrons, and modifications thereof. The absorbent cleaning device 100 illustrated in FIG. 1 comprises a body 105 and two openings 110a, 110b disposed in the body 105. In the illustrated embodiment, the openings 110a, 110b comprise slits. FIG. 2 is a cross-section of the absorbent cleaning device 100 of FIG. 1 taken through line 2-2. As illustrated, the absorbent cleaning device further comprises substantially V-shaped notches 112a, 112b at or adjacent an outside surface 115 of the body 105 and the openings or slits 110a, 110b. In other embodiments, the notches 112a, 112b may be substantially U-shaped or otherwise shaped. The notches 112a, 112b may facilitate introduction of a medical appliance or an elongate medical device into the openings or slits 110a, 110b without additional manipulation of the openings or slits 110a, 110b. For example, the notch or notches 112a, 112b may be configured to guide a medical appliance or elongate medical device into the slit or slits 110a, 110b. Slits 110a, 110b within the scope of this disclosure may also lack notches 112a, 112b. For example, narrow portions of the slits 110a, 110b may extend to or adjacent to the outside surface 115 of the body 105. Devices within the scope of this disclosure may comprise more or fewer than two openings. For example, a body, such as body 105, may comprise one, two, three, four, five, or more openings. Also, other configurations of the openings 110a, 110b including, but not limited to, apertures, cavities, channels, holes, indentations, tunnels, and modifications thereof, are within the scope of this disclosure.
In some embodiments, the body 105 may comprise an absorbent material. In other embodiments, the body 105 may further comprise a coating or covering. In yet other embodiments, the absorbent material and/or coating may be at least partially impregnated with an anticoagulant. For example, the absorbent material may be at least partially impregnated with heparin. The anticoagulant may be used to control, limit, and/or prevent coagulation of bodily fluids on the surface 115 of the absorbent cleaning device 100, as coagulated blood on the surface 115 of the absorbent cleaning device 100 may inhibit and/or interfere with the cleaning capabilities or properties of the absorbent cleaning device 100. The anticoagulant may also control, limit, and/or reduce thrombogenesis on the surface of the absorbent cleaning device 100.
In some embodiments, the absorbent material may comprise a polymer. In certain embodiments, the polymer may comprise polyvinyl acetate, polyvinyl alcohol, or polyvinyl fluoride (PVF). In certain embodiments, the polymers may or may not be cross-linked. In certain other embodiments, the polymer may comprise a hydrophilic cross-linked polymer including, but not limited to, polyhydroxyethylmethacrylate (pHEMA), a polyacrylate, a cross-linked polyacrylic acid, and a cross-linked polyamine derivative. In yet other embodiments, the absorbent cleaning device 100 may comprise a hypoallergenic material. In still other embodiments, the absorbent material may be substantially non-fibrous or non-particulate. The absorbent cleaning device 100 may also comprise a substantially non-fibrous or non-particulate absorbent material, as fibers or particles, which, if introduced or released into an individual or a patient, may generate granulomas or be otherwise deleterious.
The absorbent material may comprise pores such that the body 105 may be configured to absorb two or more times its dry weight in fluid. In other embodiments, the body 105 may be configured to absorb 12 or more times its dry weight in fluid, including four times or more and eight times or more its dry weight in fluid. Additionally, the absorbent cleaning device 100 may be at least partially impregnated with a cleaning solution. In some embodiments, the absorbent cleaning device 100 may be at least partially impregnated with a saline solution. The absorbent cleaning device 100 may also be configured to be coupled to a fluid reservoir (i.e., an IV bag). The fluid reservoir may contain an anticoagulant, cleaning solution, and/or saline solution and be configured to keep the absorbent cleaning device 100 hydrated or moist. In some embodiments, the absorbent cleaning device 100 may be configured to hydrate or moisten a portion of an accommodated medical appliance or elongate medical device, or the absorbent cleaning device 100 may be configured to maintain an accommodated medical appliance or elongate medical device in a hydrated or moistened state. For example, a guide wire or other device may be configured with a hydrophilic coating. Maintenance of the hydration of such a coating may increase the lubricity, cleanliness, and/or handling of the guide wire during surgery or therapy.
In some embodiments, the body 105 may be compressible when pressure is applied to the body 105, and the body 105 may substantially return to an uncompressed configuration when pressure is released. Stated another way, the body 105 may comprise a shape-memory material such that the body 105 may at least generally or substantially return to an uncompressed state upon removal of an applied force and/or pressure.
The body 105, as illustrated in FIG. 2, may comprise a substantially planar surface 108 and the substantially planar surface 108 may be substantially oval. In other embodiments, wherein the body 105 is not substantially ovoid, the substantially planar surface 108 may comprise another shape including, but not limited to, a circle, octagon, parallelogram, pentagon, rectangle, square, trapezoid, triangle, or modification thereof. The substantially planar surface 108 may control and/or reduce movement or rolling of the absorbent cleaning device 100 when it is placed or set on a surface, such as a patient's body. Thus, the shape of the body 105 generally, including the presence or position of a substantially planar surface 108 may tend to stabilize the body 105 during use. In some other embodiments, the absorbent cleaning device 100 may comprise a first substantially planar surface on a first surface of the body 105 and a second substantially planar surface on a second surface of the body 105. Such a configuration may allow or permit two or more absorbent cleaning devices 100 to be stacked on top of one another.
In some embodiments, the absorbent cleaning device 100 may further comprise a mechanism configured to adhere or secure the absorbent cleaning device 100 to a surface (i.e., a table or wall). In one embodiment, an adhesive may be coupled to or present on at least a portion of the body 105, for example, on a portion of the substantially planar surface 108. The adhesive may also be coupled to or present on at least a portion of the surface 115 of the absorbent cleaning device 100 not comprising a substantially planar surface 108. In some embodiments, an adhesive may be covered prior to use. In one example, a practitioner may peel off or remove a covering to expose an adhesive on at least a portion of the surface 115 of the absorbent cleaning device 100. The practitioner may then adhere or secure the absorbent cleaning device 100 to a surface during a medical procedure or therapy. A practitioner may also opt not to expose the adhesive, allowing the practitioner to lift or otherwise displace the absorbent cleaning device 100 during therapy.
Referring to FIGS. 1 and 2, in the illustrated embodiment, the openings 110a, 110b comprise slits extending inwardly from the outside surface 115 of the body 105. In some embodiments, the openings or slits 110a, 110b may extend from the substantially planar surface 108 of the body 105. In the illustrated embodiment, the openings or slits 110a, 110b extend from a surface other than the substantially planar surface 108. In another embodiment, a depth of the slits 110a, 110b may extend less than one-half of a depth of the body 105 along the direction of the slit 110a, 110b. In other embodiments, the absorbent cleaning device 100 may not comprise a substantially planar surface 108. Further, the openings or slits 110a, 110b may also be positioned at any location on the body 105. There may be more than one opening, and/or the opening or openings may extend in a direction perpendicular to the configuration illustrated in FIG. 1.
Further, the openings or slits 110a, 110b may extend in a direction perpendicular to a substantially planar surface 108 of the body 105 or at any other angle with respect to a substantially planar surface 108 of the body 105. The openings or slits 110a, 110b may extend from an outside surface of the body 105 along a radius of a circular or substantially circular cross-section of the body 105 and/or extend toward a centroid or focus of a cross-section of the body 105. Additionally or alternatively, the openings or slits 110a, 110b may extend along a maximum direction of a cross-section of the body 105, meaning the direction is a maximum dimension across the cross-section. The openings or slits 110a, 110b may be configured to extend into the body 105 while allowing the body 105 sufficient structure to generally maintain its shape. Other configurations of the opening or openings are also contemplated.
The openings or slits 110a, 110b of FIGS. 1 and 2 are configured to accommodate a portion of a medical appliance or an elongate medical device. In some embodiments, the elongate medical device may be selected from at least one of a catheter, introducer, snare, tube, and/or wire. Other elongate medical devices are also within the scope of this disclosure. In some embodiments, the opening or slits 110a, 110b may be configured to clean the medical appliance or the elongate medical device. In other embodiments, the opening or slits 110a, 110b may be configured to retain, hold, or otherwise secure the elongate medical device. For example, the slits 110a, 110b may hold or secure the position of one or more guide wires during a wire-based intervention. For example, a practitioner may dispose a portion of a guide wire within a slit 110a or 110b during a procedure. Interaction between opposing walls of the slit 110a or 110b and the guide wire may tend to maintain the position of the guide wire with respect to the body 105. The practitioner may subsequently remove the guide wire from the slit 110a or 110b and/or displace the entire body 105 to displace the guide wire.
The slits 110a, 110b may comprise narrow cuts in the body 105. The shape and form of the body 105, along with the narrowness of the slits 110a, 110b may tend to maintain the slits 110a, 110b in a closed configuration. In other words, opposing walls defined by the slits 110a, 110b may tend to remain in contact with each other when the body 105 is unconstrained. In some embodiments, the slits 110a, 110b may be configured to remain in a closed configuration such that opposing walls of the slits 110a, 110b are in contact when the body 105 is in an unconstrained configuration.
In some embodiments, the body 105 may be cupped or at least partially hollow. In some instances, cupping of the body 105 may tend to introduce a biasing effect to further maintain the closed configuration of the slits 110a, 110b. For example, a lower surface of the body 105 may be cupped and slit or slits 110a, 110b may be disposed on an upper surface of the body 105. The cupped configuration may tend to introduce a stress that will maintain the slits 110a, 110b in a closed configuration. Again, the slits 110a, 110b may be self-closing regardless of whether the body 105 is cupped. Thus, in some embodiments, an external force or pressure may not be required to transition the slits 110a, 110b from an open configuration to a closed configuration.
Referring again to FIGS. 1 and 2, the illustrated body 105 comprises a textured outside surface 115. As illustrated, the outside surface 115 comprises a series of annular steps extending circumferentially around the body 105. Other patterns or textures are also within the scope of this disclosure. For example, the surface of the body 105 may be substantially covered with a series of dimples. The textured surface 115 may act to enhance friction upon contact and/or agitation between gloves, medical appliances, or elongate medical devices and the textured surface 115 of the absorbent cleaning device 100. Such friction may enhance the ability of the absorbent cleaning device 100 to remove bodily fluids, tissue fragments, medical contrast media, and/or other matter from the surface of gloves, medical appliances, or elongate medical devices. In other embodiments, the surface 115 may be substantially smooth.
FIG. 3A illustrates an exemplary method for using an absorbent cleaning device 100 as disclosed herein. In the exemplary method, a user 135 may introduce a portion of an elongate medical device 130 into one of the slits 110a, 110b of the absorbent cleaning device 100. In some embodiments, the illustrated absorbent cleaning device 100 may be used to clean other types of medical appliances. The user 135 may then agitate or rub the portion of the elongate medical device 130 against walls of the slit 110a or 110b to clean and/or remove matter from the surface of the elongate medical device 130. The user 135 may also transition the elongate medical device 130 between at least a first position and a second position within the slit 110a or 110b such that the surface of the elongate medical device 130 is at least partially cleaned. In another embodiment of the method of FIG. 3A, the method may comprise the step of at least partially impregnating or re-impregnating the absorbent cleaning device 100 with a cleaning solution and/or a saline solution.
FIG. 3B illustrates an exemplary method of using the absorbent cleaning device 100 of FIG. 1 to secure two elongate medical devices 130. In the exemplary method, the user 135 may introduce portions of elongate medical devices 130 into slits 110a, 110b of an absorbent cleaning device 100. The user 135 may then adjust positions of the portions of the elongate medical devices 130 within the slits 110a, 110b such that the elongate medical devices 130 are secured with respect to the body 105. In some embodiments, opposing walls of the slits 110a, 110b may tend to contact the elongate medical devices 130 when the absorbent cleaning device 130 is unconstrained.
As illustrated in FIG. 3B, the slits 110a, 110b may be configured to retain or secure elongate medical devices 130 disposed therein. Such retention or securement may result from friction between the opposing walls of the slits 110a, 110b and the elongate medical device 130. For example, the slits 110a, 110b may be configured to retain an elongate medical device 130 disposed therein through friction between opposing walls of the slits 110a, 110b and the elongate medical device 130. In some embodiments, opposing walls of the slits 110a, 110b may tend to contact the elongate medical device 130 when the absorbent cleaning device 100 is unconstrained. The user 135 may introduce one or more elongate medical devices 130 into one or more slits 110a, 110b such that the elongate medical device or devices 130 are retained or secured in place. For example, a catheter may be held or secured with respect to the body by introduction of the catheter into a slit of an absorbent cleaning device during a surgical procedure. In some embodiments, the absorbent cleaning device 100 may comprise more or fewer than two slits 110a, 110b. For example, a body, such as body 105, may comprise one, two, three, four, five, or more slits. Consequently, in other embodiments, the absorbent cleaning device 100 may be configured to retain or secure more or fewer than two elongate medical devices 130. A body 105 configured to secure other devices or components may or may not be configured as a cleaning absorbent device.
FIG. 4 is a side view of one embodiment of an absorbent cleaning device 200. FIG. 5 is a perspective view of the top of the absorbent cleaning device 200 of FIG. 4, and FIG. 6 is a perspective view of the bottom of the absorbent cleaning device 200 of FIG. 4. The illustrated absorbent cleaning device 200 is substantially ovoid, prolate spheroid, or American-football shaped. As discussed above, it will be appreciated by one skilled in the art having the benefit of this disclosure that absorbent cleaning devices as described herein may comprise other shapes including, but not limited to, cones, cubes, cuboids, cylinders, dodecahedrons, octahedrons, prisms, pyramids, spheres, hemispheres, tetrahedrons, and modifications thereof. The dashed line of FIG. 4 indicates the position of an opening 210 in one configuration. As illustrated in FIGS. 4 and 6, the opening 210 comprises an elongate channel. Other configurations of the opening 210, however, including, but not limited to, apertures, cavities, holes, indentations, slits, tunnels, and modifications thereof, are also within the scope of this disclosure.
The embodiment of FIGS. 4-7 may include components that resemble components of the embodiment of FIGS. 1 and 2 in some respects. For example, the embodiment of FIG. 4 includes a body 205 that may resemble the body 105 of FIG. 1. It will be appreciated that all the illustrated embodiments have analogous features. Accordingly, like features are designed with like reference numerals, with leading digits added to increment each reference numeral by 100. (For instance, the body is designated “105” in FIG. 1 and an analogous body is designated as “205” in FIG. 4.) Relevant disclosure set forth above regarding similarly identified features thus may not be repeated hereafter. Moreover, specific features of the absorbent cleaning device and related components shown in FIG. 4 may not be shown or identified by a reference numeral in the drawings or specifically discussed in the written description that follows. However, such features may clearly be the same, or substantially the same, as features depicted in other embodiments and/or described with respect to such embodiments. Accordingly, the relevant descriptions of such features apply equally to the features of the absorbent cleaning device and related components of FIG. 4. Any suitable combination of the features, and variations of the same, described with respect to the absorbent cleaning device and components illustrated in FIG. 1, can be employed with the absorbent cleaning device and components of FIG. 4, and vice versa. This pattern of disclosure applies equally to further embodiments depicted in subsequent figures and/or described hereafter.
Referring to FIGS. 4-6, the absorbent cleaning device 200 comprises a body 205 and an opening 210 disposed in the body 205. Disclosure above regarding the position, orientation, geometry, or other characteristics of the openings or slits 110a, 110b of FIGS. 1-3 may analogously be applied to the opening 210 of FIGS. 4-6 and vice versa. In some embodiments, the body 205 may comprise an absorbent material. In other embodiments, the body 205 may further comprise a coating or covering. In yet other embodiments, the absorbent material and/or coating may be at least partially impregnated with an anticoagulant. For example, the absorbent material may be at least partially impregnated with heparin. The anticoagulant may be used to control, limit, and/or prevent coagulation of bodily fluids on a surface 215 of the absorbent cleaning device 200, as coagulated blood on the surface 215 of the absorbent cleaning device 200 may inhibit and/or interfere with the cleaning capabilities or properties of the absorbent cleaning device 200. The anticoagulant may also control, limit, and/or reduce thrombogenesis on the surface 215 of the absorbent cleaning device 200. Embodiments of absorbent cleaning devices comprising both slits (such as 110a, 110b of FIGS. 1-3) and one or more additional openings, for example channels) (such as 210 of FIGS. 4-6) are within the scope of this disclosure.
As discussed above, the absorbent material may comprise a polymer. In some embodiments, the polymer may comprise polyvinyl acetate or polyvinyl alcohol. In another embodiment, the polymer may comprise polyvinyl fluoride (PVF). In certain embodiments, the polymers may or may not be cross-linked. In other embodiments, the polymer may comprise a hydrophilic cross-linked polymer including, but not limited to, polyhydroxyethylmethacrylate (pHEMA), a polyacrylate, a cross-linked polyacrylic acid, and a cross-linked polyamine derivative. In yet other embodiments, the absorbent cleaning device 200 may comprise a hypoallergenic material. In still other embodiments, the absorbent material may be substantially non-fibrous or non-particulate, as fibers or particles, which, if introduced or released into an individual or a patient, may generate granulomas or be otherwise deleterious.
The absorbent material may comprise pores such that the body 205 may be configured to absorb two or more times its dry weight in fluid. In other embodiments, the body 205 may be configured to absorb 12 or more times its dry weight in fluid, including four times or more and eight times or more its dry weight in fluid. Additionally, the absorbent cleaning device 200 may be at least partially impregnated with a cleaning solution. In some embodiments, the absorbent cleaning device 200 may be at least partially impregnated with a saline solution. The absorbent cleaning device 200 may also be configured to be coupled to a fluid reservoir (i.e., an IV bag). The fluid reservoir may contain an anticoagulant, cleaning solution, and/or saline solution and be configured to keep the absorbent cleaning device 200 hydrated or moist.
In an embodiment, the body 205 may be compressible when pressure is applied to the body 205, and the body 205 may substantially return to an uncompressed configuration when pressure is released. Stated another way, the body 205 may comprise a shape-memory material such that the body 205 may at least generally or substantially return to an uncompressed state upon removal of an applied force and/or pressure.
The body 205 of FIG. 4 comprises a substantially planar surface 208 wherein the substantially planar surface 208 is substantially oval (see FIG. 6). In other embodiments, wherein the body 205 is not substantially ovoid, the substantially planar surface 208 may comprise another shape including, but not limited to, a circle, octagon, parallelogram, pentagon, rectangle, square, trapezoid, triangle, or modification thereof. The substantially planar surface 208 may control and/or reduce movement or rolling of the absorbent cleaning device 200 when it is placed or set on a surface, such as a patient's body. Thus, the shape of the body 205 generally, including the presence or position of a substantially planar surface 208 may tend to stabilize the body 205 during use.
In some embodiments, the absorbent cleaning device 200 may further comprise a mechanism configured to adhere or secure the absorbent cleaning device 200 to a surface (i.e., a table or a wall). In one embodiment, an adhesive may be coupled to or present on at least a portion of the body 205, for example, on a portion of the substantially planar surface 208. The adhesive may also be coupled to or present on at least a portion of the surface 215 of the absorbent cleaning device 200 not comprising a substantially planar surface 208. In some embodiments, an adhesive may be covered prior to use. In one example, a practitioner may peel off or remove a covering to reveal an adhesive on at least a portion of the surface 215 of the absorbent cleaning device 200. The practitioner may then adhere or secure the absorbent cleaning device 200 to a surface during a medical procedure or therapy. A practitioner may also opt not to expose the adhesive, allowing the practitioner to lift or otherwise displace the absorbent cleaning device 200 during therapy.
Referring to FIGS. 4 and 6, in the illustrated embodiment, the opening 210 comprises a channel extending inwardly from an outside surface 215 of the body 205. In some embodiments, as illustrated, the channel may extend from the substantially planar surface 208 of the body 205. In another embodiment, a depth of the channel may be less than one-half of a depth of the body 205 along the direction of the channel, and a width of the channel may be less than one-fourth of the depth of the channel. In other embodiments, the absorbent cleaning device 200 may not comprise a substantially planar surface 208. The opening may also be positioned at other locations and in other orientations on the body 205. For example, the opening 210 may comprise a tunnel passing through the absorbent cleaning device 200. In other examples, there may be more than one opening 210, or the opening 210 may extend in a direction perpendicular to the configuration illustrated in FIGS. 4 and 6. The opening 210 may extend into the body 205 while retaining sufficient body 105 structure that the body 205 tends to maintain its shape. Other configurations of the opening 210 are also contemplated.
FIG. 7 is an end view of the embodiment of the absorbent cleaning device 200 of FIG. 4. As illustrated, the opening or channel 210 comprises opposing walls 211a, 211b. The opposing walls 211a, 211b may be displaceable toward each other. For example, a user may apply a force to the body 205 that inwardly biases or displaces the opposing walls 211a, 211b toward one another. Upon displacement of the opposing walls 211a, 211b, the walls 211a, 211b may contact each other and/or a portion of a medical appliance or elongate medical device present in the channel 210. The channel 210 of FIGS. 4, 6, and 7 is configured to accommodate a portion of a medical appliance or an elongate medical device. In some embodiments, the elongate medical device may be selected from at least one of a catheter, introducer, snare, tube, and/or wire. Other elongate medical devices are also within the scope of this disclosure.
Referring to FIGS. 4-7, the illustrated body 205 comprises a textured outside surface 215.
