[0001] Related Applications

[0002] This application is incorporated herein by reference to U.S. Provisional Patent Application Serial No. 62 / 953,441, filed December 24, 2019, and U.S. Patent Application Serial No. 17 / 133,212, filed December 23, 2020. Technical Field

[0003] This invention relates to wound care, and more specifically to novel systems and methods for cleaning, debridement and debridement of wounds. Background Technology

[0004] Different types of devitalized tissue are commonly found in wound surfaces. This tissue can disrupt granulation and delay healing. For example, devitalized tissue may stimulate the overproduction of matrix metalloproteinases (MMPs), thus slowing the healing process. Furthermore, devitalized tissue may provide a favorable environment for bacteria. Bacterial biofilms grow on 60–90% of chronic wounds and approximately 6% of acute wounds. Bacterial biofilms are low-grade infections that can cause chronic inflammation, impair wound healing, and increase the risk of cellulitis. Various techniques and / or methods have been developed to improve wound care. However, these techniques and / or methods have certain drawbacks. For example, ultrasonic debridement (e.g., involving debridement with oscillations at frequencies of approximately 20 kHz or higher) is too expensive to be widely adopted. Conversely, pulsed irrigation is often too unhygienic for use in clinic or emergency room settings. Therefore, there is a need for improved systems and methods for cleaning, debridement, and wound cleaning, as well as for removing bacterial biofilms. Attached Figure Description

[0110] It will be readily understood that the components of the application, as generally described and illustrated in the Figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following more detailed description of the embodiments of the systems and methods of the application, as represented in the Figures, is not intended to limit the scope of the application, as claimed, but is merely representative of various embodiments of the application. The illustrated embodiments of the application will be best understood by reference to the drawings, wherein like parts are designated with like numerals throughout.

[0111] Reference is made to Figures 1-4 Debris that can be present in a wound bed can include fibrinous necrosis (mainly fibrin tissue), leukocytic necrosis (mainly WBC accumulation), necrotic slough (mainly necrotic tissue), and bio-necrosis (mainly biofilm). Slough can be defined as the devitalized tissue that mainly contains fibrin, but it can also include leukocytes, debris, etc. The presence of slough can interrupt granulation and delay healing. It can also provide an environment that is conducive to bacteria that can grow and spread within it. Wounds also present a continuum of infection that ranges from contaminated wounds (bacteria on the wound surface but not replicating), colonization (bacteria living in the wound bed and replicating), early biofilm formation, mature biofilm formation, and local to systemic infection resulting from biofilm seeding. Thus, to promote healing, the wound care device 10 according to the present application can promote the removal of devitalized tissue from the wound. This removal can be described as wound cleansing, de-sloughing, and / or debridement.

[0112] The devitalized tissue in a wound bed can have different consistencies depending on various factors. For example, the consistency of the devitalized tissue can be described as (1) mucoid (i.e., thick and soft), (2) gelatinous, (3) stringy and / or chunky, (4) fibrous, and / or (5) leathery. Depending on the consistency of the devitalized tissue, different debridement tools and / or methods can be required. For example, debridement that is suitable for "leathery" devitalized tissue can be too aggressive for "mucoid" devitalized tissue. Thus, the wound care device 10 can be adjustable or suitable for providing appropriate cleansing and / or debridement across a range of consistencies of devitalized tissue.

[0113] Bacterial biofilm can be found in 60-90% of chronic wounds and about 6% of acute wounds. Biofilm often contains multiple bacteria. Biofilm can be found in multiple places, including within the wound bed (i.e., at a depth of about 60-70 microns below the wound surface), on the wound surface, in slough, in liquid on and around the wound bed, etc., and can also migrate onto wound dressings. Thus, the wound care device 10 can be used to break down bacterial growth, prevent the formation of bacterial biofilm, and / or treat bacterial biofilm.

[0114] Wound care is complicated by the fact that it is provided by a variety of people with a variety of medical experience and / or training. For example, at home, patients with little or no medical experience or training are often responsible for providing their own wound care (e.g., responsible for applying and / or changing their own ointments). For patients with more serious wounds, wound care can be provided in their respective homes by ancillary medical personnel with varying degrees of wound care training. Some ancillary medical personnel can have an associate nursing degree. Others have a bachelor of science in nursing degree. Still others can be specialized wound, ostomy, and continence nurses (WOCN). Regardless of educational background, however, ancillary medical personnel will have varying degrees of comfort and skill in cleaning wounds and performing basic wound cleaning and / or debridement.

[0115] In long-term care environments such as nursing homes and long-term acute care (LTAC) hospitals, there can be a team of wound care personnel who have received more advanced training and have more skilled abilities due to their repeated and regular handling of complex wounds. In the offices of physicians and surgeons, wounds often require cleaning or minor surgical debridement. Such treatment is often performed in an operating room. However, such use of an operating room is often unnecessary and not only increases the cost of treatment, but can increase morbidity depending on the choice of anesthesia.

[0116] Accordingly, to address the variance in the various people responsible for providing wound care, the wound care device 10 according to the present disclosure can be easy to use. Moreover, it can be configured to limit the potential for misuse or harmful use. Accordingly, both inexperienced patients and trained medical professionals can use the wound care device 10 to obtain beneficial results.

[0117] In selected embodiments, the wound care device 10 can include a body 12 or handle portion 12 and a head 14. In other embodiments, the wound care device 10 can include a body 12, a head 14, and a fluid system 16. The head 14 can be detachably connected to the body 12. In operation, the head 14 can apply motion (e.g., vibration, oscillation, reciprocation, etc.) generated by the body 12 to a wound surface. Accordingly, the body 12 can be responsible for generating the desired motion, while the head 14 can be responsible for conducting that motion from the body 12 to the wound surface.

[0118] In certain embodiments, the body 12 can include a motion generator 18, one or more batteries 20, a controller 22, a housing 24, one or more other components 26 or structures 26, etc., or combinations or partial combinations thereof. The motion generator 18 can generate vibrations, oscillations, reciprocations, etc., at a desired frequency. One or more other structures 26 (e.g., physical linkages, shafts, etc.), the housing 24, etc., can conduct the vibrations, oscillations, or reciprocations to the head 14.

[0119] In selected embodiments, the motion generator 18 can vibrate, oscillate, reciprocate, etc. at a relatively low sonic frequency in the range from about 100 Hz to about 1000 Hz. Alternatively or additionally, the motion generator 18 can vibrate, oscillate, reciprocate, etc. at a relatively high amplitude (e.g., an amplitude in the range from about 1 millimeter to about 10 millimeters and more preferably from about 3 millimeters to about 8 millimeters). That is, once the head 14 is applied to the body 12, the vibration, oscillation, reciprocation, etc. of the motion generator 18 can produce a side-to-side sweep of about 1 millimeter to about 10 millimeters (and more preferably from about 3 millimeters to about 8 millimeters) at the distal end of the head 14, i.e., from one extreme to the other. In other embodiments, the amplitude and / or motion can be different, but can still be in the relatively low sonic frequency range. Thus, the device 10 according to the present application operates at a much lower frequency than any ultrasonic debridement device and benefits from the higher amplitudes that can be obtained at this lower frequency.

[0120] In selected embodiments, the motion generator 18 can include an electromagnet whose polarity is alternated at a desired frequency to produce the desired vibration, oscillation or reciprocation (e.g., a desired vibration, oscillation or reciprocation in a linkage that is engaged with the head 14). In other embodiments, the motion generator 18 can include a motor that rotates a shaft having an eccentric weight affixed thereto to produce the vibration, oscillation or reciprocation effect.

[0121] For example, the motion generator 18 can include a motor that has a rated speed of about 9,000 to about 36,000 revolutions per minute (preferably about 18,000 to about 22,000 revolutions per minute) when a rated load (e.g., an eccentric mass of about 0.5 to about 1.0 grams, preferably about 0.75 grams) is applied to its shaft. This speed can be translated into a vibration, oscillation, reciprocation, etc. in the sonic range of about 150 Hz to about 600 Hz, where each cycle can include two strokes (e.g., one leftward stroke or deflection and one rightward return stroke or deflection) across the wound bed. Thus, a motion generator 18 operating at about 150 Hz can produce about 300 vibration strokes per second, while a motion generator 18 operating at about 600 Hz can produce about 1,200 vibration strokes per second.

[0122] The motion generator 18 can create vibrations, oscillations, and / or reciprocating motion in the linkage 28 or other structure 28 extending to engage the head 14. For example, in selected embodiments, an end of the main portion 12 can include or form a horn 28, and the motion generator 18 can be positioned within the horn 28. When the motion generator 18 is "turned on," the horn 28 can be caused to vibrate, oscillate, and / or reciprocate at a desired frequency. Thus, when the horn is inserted or otherwise connected to a correspondingly shaped head 14, the horn 28 can transfer that vibration, oscillation, and / or reciprocation to the head 14.

[0123] In selected embodiments, the structural configuration of the horn 28, the head 14, or the horn 28 and head 14 combination can define the type or shape of motion created by the motion generator 18. For example, by selecting where the mass is positioned, a preferred axis of bending or deflection (i.e., an axis that has little resistance to bending or deflection), or a combination thereof, the motion of the head 14 can be defined as a more circular fore and aft rocking, side to side translation, or the like, in order to provide a desired effect, action, or operation on a wound bed.

[0124] The battery 20 can provide the power needed for the motion generator 18. In selected embodiments, the battery 20 can be rechargeable. For example, the battery 20 (e.g., a lithium ion battery) can include or be connected to a receiving coil or secondary coil to enable or support wireless charging when the corresponding device 10 is placed on or in a charging station. Alternatively or additionally, the device can be at least partially powered and / or charged by one or more supercapacitors.

[0125] The controller 22 can control the operation of the body 10. In selected embodiments, the controller 22 can include a switch 30 for turning the motion generator 18 on and off. Alternatively or additionally, the controller 22 can include a printed circuit board (PCB) 32, one or more integrated circuits, one or more processors (e.g., an application specific integrated circuit (ASIC), a programmable logic controller (PLC)), memory, or the like, or a combination or partial combination thereof in order to control the motion generator 18. Thus, the controller 22 can automatically control certain functions of the wound care device 10.

[0126] For example, the controller 22 can turn the motion generator 18 off if the battery is low, a certain time interval (e.g., 2 to 3 minutes) has elapsed since the device 10 was turned on, or the like. The controller 22 can control the speed and / or power of the device 10 through one or more switches 30, buttons 30, or the like that can be operated by a user. In selected embodiments, the controller 22 can adjust or regulate the voltage of the current flowing from the battery 20 or other power source to the motion generator 18 as needed or necessary (e.g., increase the voltage from 3.0 V to 3.7 V or some other desired voltage).

[0127] In selected embodiments, the controller 22 can emit a drum beat, temporarily pause the vibration, emit a beep, flash a light, etc. at predetermined regular time intervals (e.g., every 30 seconds) so that the user can more easily monitor and control the time spent cleaning or debriding the wound. Thus, a physician can instruct a patient or home health nurse to use the device 10 to clean a minor wound for 30 seconds, a major wound for 90 seconds, etc. The patient or nurse can then observe the appropriate number of drum beats or beeps to meet the prescribed treatment time.

[0128] The housing 24 can incorporate various other components of the body 12. For example, the housing 24 can incorporate and provide structure for mounting or anchoring the motion generator 18, the battery 20, the controller 22, etc. In selected embodiments, the housing 24 can form a handle. Thus, the user can grasp and hold the housing 24 when using the wound care device 10.

[0129] In certain embodiments, the head 14 can include a frame 34, a contact surface 36, one or more other components 38 or structures 38, etc. or combinations or partial combinations thereof. The frame 34 can extend from the body 12 to support the contact surface 36. For example, the frame 34 can engage the physical linkage 28, the horn 28, etc. that is selectively vibrated, oscillated and / or reciprocated by the motion generator 18. Thus, the frame 34 can conduct the vibrations, oscillations and / or reciprocations originating from the motion generator 18 to the contact surface 36.

[0130] The contact surface 36 can be configured to contact the wound surface. In selected embodiments, the head 14 can be considered to have a front face 40 and a back face 42. In such embodiments, the contact surface 36 can be or correspond to the front face 40 of the head 14. Thus, the contact surface 36 can be configured to provide the desired cleaning, debriding, etc.

[0131] In certain embodiments, the contact surface 36 can be selectively separable from the corresponding frame 34. Thus, the user can obtain or control the cleaning, debriding or debriding effect by selecting and installing a contact surface 36 designed to provide the cleaning, debriding or debriding effect. Alternatively, the contact surface 36 can be integrally or substantially permanently connected to the frame 34. Thus, in certain embodiments, the user can obtain or control the cleaning, debriding or debriding effect by selecting and installing a head 14 having a contact surface 36 designed to provide the cleaning, debriding or debriding effect.

[0132] In selected embodiments, the contact surface 36 can be configured for single use. For example, the contact surface 36 (or the head 14 including the frame 34 and the contact surface 36) can be provided to a user under aseptic conditions and within a sterile package. After use on a wound, the contact surface 36 will no longer be sterile and can have significant bacterial contamination. Accordingly, the contact surface 36 (or the head 14 including the frame 34 and the contact surface 36) can be discarded and a new contact surface 36 (or a new head 14) can be used for the next cleaning, debridement, or debridement.

[0133] The fluid system 16 can facilitate wound cleaning, debridement, and / or debridement. Fluid provided or delivered by the fluid system 16 can tend to flush loose material and particulate out of a wound bed. For example, fluid delivered onto a central location on the contact surface 36 can tend to flush outward (e.g., radially outward) and across the contact surface 36 (e.g., within various channels formed in the contact surface 36) to help remove, move, and flush out bacteria, toxins, and cellular debris and prevent clogging of the contact surface 36. Alternatively or additionally, the fluid can tend to soften material being removed to help (e.g., speed up) their removal.

[0134] In selected embodiments, the fluid system 16 can include a reservoir 44, a compression element 46, one or more other components 48 or structures 48, etc., or combinations or partial combinations thereof. The reservoir 44 can contain fluid (e.g., saline, an antibiotic or antiseptic in liquid form, a gel, a paste, etc.). The reservoir 44 can be deformable. Deformation of the reservoir 44 can tend to expel fluid therefrom. Accordingly, manual deformation (e.g., squeezing, flattening, etc.) of the reservoir 44 can provide motive force for expelling fluid from the reservoir 44 and / or control the rate at which fluid is expelled from the reservoir 44.

[0135] In certain embodiments, the reservoir 44 can be directly manually compressed by a user's hand or fingers. In other embodiments, a compression element 46 can be included to help compress the reservoir 44. The compression element 46 can be a structure or combination of structures that facilitate deformation (e.g., compression) of the reservoir 44. For example, the compression element 46 can be a structure that holds the reservoir 44 in place along the housing 24 (e.g., along the underside of the housing 24) so that a user can hold the device 10 and simultaneously squeeze the reservoir 44 (e.g., with the same hand). Alternatively or additionally, the compression element 46 can include levers that operate with the housing 24 so that the reservoir 44 can be squeezed therebetween. Accordingly, by pulling the levers, fluid can be expelled from the reservoir 44 using the same hand that the user holds the body 12.

[0136] In selected embodiments, the wound care device 10 can include a conduit 50. The conduit 50 can extend to place the reservoir 44 in fluid communication with the head 14. Thus, manual deformation of the reservoir 44 can push fluid out of the reservoir 44 and into the conduit 50. The fluid can then travel through the conduit 50 until it reaches the head 14, where it can be discharged proximate the contact surface 36. In other embodiments, the fluid conduit 50 (or selected portions of the fluid conduit 50) can be integral with the head 14.

[0137] The conduit 50 can include a check valve 52, a disconnect 54, one or more other components 56 or structures 56, etc., or combinations or partial combinations thereof. The check valve 52 can allow fluid to flow from the reservoir 44 to the head 14 and prevent fluid from flowing from the head 14 back to the reservoir 44. This can prevent contaminated fluid from being drawn into the wound care device 10. In certain embodiments, the check valve 52 can be part of the reservoir 44 rather than part of the conduit 50. In other embodiments, the check valve 52 can be part of the head 14 rather than part of the conduit 50. However, wherever the check valve 52 is located, it can force the same one-way fluid flow.

[0138] The one or more disconnects 54 can enable the conduit 50 to be selectively connected to and / or disconnected from the reservoir 44, the head 14, etc. Alternatively, the conduit 50 can simply have one or more ends that can be inserted into or over appropriately sized holes or ports of the head 14 or the reservoir 44 to enable fluid to flow through the resulting interface. In either case, the conduit 50 can be selectively connected to and disconnected from the head 14, the reservoir 44, or both the head 14 and the reservoir 44. Thus, the head 14, the reservoir 44, and the conduit 50 can be installed, removed, and / or discarded as needed.

[0139] In selected embodiments, the fluid system 16 and the conduit 50 can be omitted from the wound care device 10. In such embodiments, cleaning, debriding, and / or debridement of a wound bed can be performed in a "dry" manner without the addition of any fluid. Alternatively, fluid can be applied in a separate procedure. For example, a liquid, gel, paste, etc. can be applied to a wound bed in a first procedure that precedes and is separate from the use of the wound care device 10 according to the present application to clean, debride, or debride a wound bed.

[0140] In selected embodiments, the device 10 can be provided or used in combination with one or more disposable (e.g., single-use) enclosures so that the device 10 or portions of the device 10 (e.g., the body 12 or the handle portion 12) can be safely reused between patients without contaminating the device 10. In such embodiments, to configure the device 10 for use, a new and / or clean (e.g., sterile) head 14 and enclosure can be applied to the body 12 so that all surfaces that come into contact with the patient and care giver are clean. In certain embodiments, the enclosure can cover the horn 28 and the housing 24, and the head 14 can slide over the enclosure when mounted on the horn 28.

[0141] Referring to Figure 5 In selected embodiments, the method 58 for cleaning, debriding, and / or debridement of a wound bed can begin when the device 10 is configured 60 for use. Configuring 60 the device 10 for use can include selecting and installing an appropriate contact surface 36 or head 14, selecting and installing a reservoir 44 and / or conduit 50, etc., or combinations thereof. Thereafter, the device 10 can be“turned on” 62 (e.g., begin oscillation or other movement of the head 14), and the contact surface 36 can be positioned 64 proximate the wound bed.

[0142] To begin cleaning, debriding, and / or debridement, the user can manually squeeze 66 the reservoir 44 to create a flow of fluid to the contact surface 36 and / or place 68 the contact surface 36 in contact with the wound bed. Thereafter, the user can move 70 the contact surface 36 over the wound bed. The vibration or other movement of the contact surface 36 alone or in combination with the rinsing action created by the fluid can tend to clean, remove, and / or debride the wound bed. Thus, the user can continue to dispense 66 fluid, apply 68 the contact surface 36 to the wound bed, and move 70 the contact surface 36 over the wound bed until it is determined 72 that cleaning, debriding, and / or debridement is complete. Once complete, the device 10 can be“turned off” 74.

[0143] Referring to Figure 6 and Figure 7 In selected embodiments, the frame 34 of the head 14 can have holes 76 to support securement to the body 12. In certain embodiments, the shape and size of such holes 76 can selectively receive (e.g., via a mating taper frictional engagement) a physical linkage 28, horn 28, etc., that conducts vibration, oscillation, and / or reciprocating motion from the body 12 to the head 14.

[0144] In certain embodiments, a hole 78 can be formed in the head 14 to enable passage of fluid therethrough. For example, the head 14 can include a hole 78 extending from the back 42 to the front 40 of the head 14. A front portion 78a of the hole 78 can be centrally positioned relative to the contact surface 36. Thus, when fluid is expelled through the front portion 78a of the hole 78, the fluid can flow, migrate, or otherwise move radially outward relative to the contact surface 36. Such radial flow or movement can tend to clean or flush the contact surface 36. A rear portion 78b of the hole 78 can be sized and shaped to receive and secure (e.g., frictionally secure) one end of the conduit 50 therein, thereby placing the hole 78 in fluid communication with the reservoir 44. In embodiments where the device 10 does not include the fluid system 16 and the conduit 50, the hole 78 in the head 14 can be omitted.

[0145] The contact surface 36 according to the present disclosure can have any suitable configuration. Suitable configurations can vary in shape (e.g., rectangular, circular, diamond, oval, etc.), size (e.g., having a length and width in a range from about 5 millimeters to about 30 millimeters, with a length of about 28 millimeters being preferred, and a width of about 14 millimeters being preferred), surface area (e.g., having a footprint of about 200 square millimeters to about 400 square millimeters, with a footprint of about 300 square millimeters being preferred), surface contour (e.g., flat, convex, etc.), surface texture or topography (e.g., sharp, rounded, coarse, fine, etc.), channels (e.g., no channels, radial channels, orthogonally intersecting channels, circumferential channels, etc., or combinations or subcombinations thereof), composition (e.g., solid polymer, solid elastomeric polymer, silicone, open cell foam, closed cell foam, etc.), hardness, etc., or various combinations or subcombinations thereof. Thus, the configuration can be selected to provide desired performance.

[0146] In selected embodiments, the contact surface 36 can be formed of a silicone elastomer or some other polymer having a variety of hardnesses (e.g., a Shore A hardness in a range from about 15 to about 100, a Shore D hardness in a range from about 40 to about 90, or a Rockwell R hardness in a range from about 50 to about 100). In certain embodiments, the contact surface 36 can include a base 80 and one or more extensions 82 extending from the base 80. The base 80 and the one or more extensions 82 can be formed of different materials to support different functions. For example, the base 80 can be formed of a material (e.g., a polymer) that is easy to mold and relatively rigid, while the one or more extensions 82 can be formed of a material (e.g., an elastomer having a desired Shore A hardness) that is compatible with cleaning, debriding, and / or debridement wound functions. In selected embodiments, the one or more extensions 82 can be insert molded or otherwise embedded within the base 80 to enable the extensions 82 to extend securely away from the base 80 and define the texture or topography of the contact surface 36.

[0147] In selected embodiments, the number and sharpness of the edges of one or more extensions 82, the pointedness of one or more extensions 82, the height of one or more extensions 82, the lateral offset of one extension 82 relative to one or more adjacent extensions 82, the hardness of the material forming one or more extensions 82 (e.g., polymer, elastomer, etc.), and / or the pressure applied by the user (e.g., the force with which the user pushes the contact surface 36 against the wound bed) can be used to control the aggressiveness of the cleaning, debridement, and / or debridement. Thus, extensions 82 that provide a high concentration of sharp edges formed from a relatively hard material can result in a very aggressive contact surface 36, whereas extensions 82 with little or no sharp edges (e.g., rounded edges) and / or extensions 82 formed from a relatively soft material can provide a very gentle contact surface 36. During use of the device 10, fluid dispensed from the one or more openings 78a can flow over and between the extensions 82 and flush debris from the contact surface 36. This flushing action can better clean the wound bed and facilitate the displacement and removal of bacteria, biofilm, and devitalized tissue during cleaning, debridement, and / or debridement.

[0148] In certain embodiments, different extensions 82 of a particular contact surface 36 can have different edges and / or hardnesses associated therewith. For example, extensions 82 associated with the ends (e.g., distal and proximal ends) of the contact surface 36 can be formed from a harder material than the centrally located extensions 82. Alternatively or additionally, the extensions 82 associated with the ends (e.g., distal and proximal ends) of the contact surface 36 can have sharper edges than the centrally located extensions 82. Thus, a user can apply different portions of the contact surface 36 to a wound bed to provide different effects.

[0149] Referring to Figure 8 and 9 In selected embodiments, the contact surface 36 can be formed as a shoe 84 (e.g., a shoe formed from an elastomer) that slides over a support structure 86 formed as part of the frame 34. In such embodiments, the shoe 84 can form (e.g., integrally form) one or more extensions 82 and a base 80 from which the one or more extensions 82 protrude. Such embodiments can allow selected portions of the head 14 to be reusable and allow the shoe 84 to include the contact surface 36 and be a disposable article formed from a very inexpensive elastomeric material to reduce the cost of use of the device. This can also simplify manufacturing, facilitate interchangeability, etc. Alternatively, the shoe 84 can be applied to the frame 34 in a two-step overmolding process. In such embodiments, the resulting head 14 can be a disposable article as a whole.

[0150] In certain embodiments, the detachable contact surface 36 (e.g., the base 80 portion of the contact surface 36) can include a length of tubing 87 extending away from the rear portion. The conduit 50 of the fluid system 16 can be connected to such tubing to deliver fluid to the contact surface 36. Thus, in such embodiments, the fluid can never contact the frame 34. The length of the tubing 87 can be selected so as to reduce the likelihood of bio-contamination of the conduit 50. In selected embodiments, the length of the tubing 87 can be from about 1 centimeter to about 13 centimeters. As a result, the contact surface 36 and associated tubing 87 can be discarded after use, while the conduit 50 can be used multiple times.

[0151] Reference Figures 10-13 In selected embodiments, the wound care device 10 can be configured for maximum utility and minimum cost. Thus, in certain embodiments, the wound care device 10 according to the present application can be non-electric (e.g., the motion generator 18 and corresponding or related structures 20, 22, 24, 28 can be omitted from the device 10). Alternatively or additionally, the wound care device 10 can be disposable. For example, in selected embodiments, the wound care device 10 can include a body 12 or handle portion 12 that is integrally formed with the head 14 (e.g., the body 12 and head 14 can be injection molded as a single unit). The material forming the body 12 and head 14, including the contact surface 36 of the head 14, can be homogeneous throughout. This can reduce the manufacturing cost of the device 10 according to the present application, make the device 10 viable as a disposable device 10, and avoid all of the sanitation and sterilization issues associated with re-use of any portion of the device 10.

[0152] In certain embodiments, the material used to form the body 12 and head 14 of the device 10 can be or reflect a compromise between the structural requirements of the body 12 and head 14 and the structural requirements of the contact surface 36 of the head 14. In selected embodiments, the material can be or include a polymer having a Rockwell R hardness of about 100 or less. For example, the material can be or include a polypropylene (e.g., a polypropylene random copolymer having a Rockwell R hardness of about 90 and a flexural modulus of about 966 MPa). Thus, in certain embodiments, the wound care device 10 can include a body 12, head 14, and contact surface 36 integrally formed (e.g., injection molded as a single unit) of a polymeric material such as polypropylene.

[0153] The fluid system 16 paired with the simplified body 12 and head 14 can be similarly simplified. For example, the conduit 50 can be omitted and the fluid system 16 can include a reservoir 44 (e.g., in the form of a squeeze bottle, a disposable container, a saline bulb, etc.) having an outlet 88 that directly engages (e.g., is inserted into the mating rear portion 78b of) the aperture 78 of the head 14. In certain embodiments, the reservoir 44 can be a sterile, single-use 15 ml saline bulb.

[0154] In selected embodiments, the body 12 or handle portion 12 of the device 10 can have a recess 90 formed therein. The recess 90 can be sized and shaped to at least partially support the reservoir 44 therein. For example, the reservoir 44 (e.g., a squeeze bottle, a saline bulb, etc.) can have a cylindrical sidewall. Accordingly, the recess 90 of the body 12 can have an inner surface 92 that conforms to, tracks, or otherwise supports at least a portion of the cylindrical sidewall of the reservoir 44. Such support can secure the reservoir 44 in place, alone or in combination with the insertion of the outlet 88 of the reservoir 44 into the aperture 78 of the head 14, or make it easier for a user to maintain the reservoir 44 in place during use (e.g., during movement of the device 10 relative to the wound bed and / or squeezing of the reservoir 44 to expel fluid).

[0155] In certain embodiments, the outer surface 94 of the body 12 can track or conform to the inner surface 92. Alternatively or additionally, the spacing between the inner surface 92 and the outer surface 94 can be relatively small. Accordingly, the thickness of the material forming the body 12 (e.g., the thickness of the material between the inner surface 92 and the outer surface 94) can be relatively thin and / or substantially uniform. This can reduce the amount of material needed to produce the device 10. Moreover, in selected embodiments, the curved surface of the body 12 that creates the recess 90 can effectively define or form at least one corrugation that extends longitudinally from one end of the body 12 to the other. Such a corrugation can stiffen the body 12 against bending without requiring a large or relatively large amount of material.

[0156] In selected embodiments, the body 12 can extend along a first direction 96 (e.g., can have a line or axis of symmetry that extends along the first direction 96). The head 14 can extend away from the body 12 along a second direction 98 that is different from the first direction 96 (e.g., can have a line or axis of symmetry that extends along the second direction 98 that is different from the first direction 96). For example, in certain embodiments, the head 14 can extend away from the body 12 along a second direction 98 that deviates from the first direction 96 at an angle 100 that is in the range of about 25 to about 55 degrees and preferably in the range of about 40 to about 50 degrees. In selected embodiments, the head 14 can extend away from the body 12 along a second direction 98 that deviates from the first direction 96 at an angle 100 of about 45 degrees.

[0157] In selected embodiments and / or uses, the reservoir 44 can be omitted from the device 10 that includes the combination of the simplified body 12 and head 14. In such embodiments, the cleaning, debridement, and / or debridement of a wound bed can be performed in a "dry" manner without the addition of any fluid. Alternatively, fluid can be applied in a separate procedure. For example, a liquid, gel, paste, etc. can be applied to the wound bed in a first procedure that precedes and is separate from the use of the wound care device 10 according to the present application to clean, debride, or debride the wound bed.

[0158] When the reservoir 44 is omitted, the recess 90 formed in the body 12 can provide a location for a user's finger (e.g., index finger) to extend and rest during use of the corresponding device 10. That is, the recess 90 can support a user's finger (e.g., index finger) rather than supporting a reservoir 44 (e.g., a saline bulb 44 having a diameter about equal to or slightly greater than a typical finger diameter). When using the device 10 in this manner, the user can place the tip of any finger supported within the recess 90 against the structure 104 or proximal end 102 of the conduit 104 that forms the rear portion 78b of the aperture 78 extending through the head 14. This engagement or abutment with the tip of the finger can enable the user to apply the desired or sufficient pressure to the head 14 when it contacts the wound bed, and / or to better perceive or control how much pressure is applied to the wound bed by the head 14.

[0159] In certain embodiments, the finger positioned within the device 10 can enable the user to selectively apply a particular region or contact surface 36 of the head 14 (e.g., the distal end of the head 14, either side of the head 14, the proximal end of the head 14) to the wound bed with greater user-applied control and angle of the contact surface 36 relative to the wound bed. This can enable the user to better control the pressure and location of the engagement between the head 14 and the wound bed and provide better results or performance for the medical procedure.

[0160] In selected embodiments, the combination of the simplified body 12 and the head 14 can be distributed in individually packaged, sterile condition. In certain embodiments, a plurality of individually packaged devices 10 can be combined into a selected number of packages (e.g., about five or some other number of packages corresponding to about a two-week supply). Thus, when attending to a patient, a medical professional can select a package of devices 10, open and use one device 10 to clean, remove, or debride a wound bed of a patient and / or teach the patient how to do so, and then leave the patient with the remaining unopened devices 10 in the package for the patient to use during the time until the patient's next visit to the medical professional. In certain embodiments, such a package can include a selected number of fluid-containing reservoirs 44 or provide the patient with a selected number of such reservoirs 44 (e.g., a selected number of saline bulbs sized to fit the combination of the simplified body 12 and the head 14).

[0161] Referring to Figure 14 In selected embodiments, the proximal end 102 of the structure 104 or conduit 104 forming the rear portion 78b of the aperture 78 extending through the head 14 can be shaped to comfortably engage a user's fingertip. For example, the proximal end 102 can have a curved surface 106 formed therein that approximates or replicates a portion of the curved surface of a fingertip. Thus, the structure 104 or conduit 104 can be configured to alternately and with equal efficiency engage both the outlet 88 of the reservoir 44 and a user's fingertip.

[0162] In certain embodiments, the structure 104 or conduit 104 can be sized and shaped to engage the conduit 50 with a luer taper linkage. For example, the interior surface of the aperture 78 can be sized and shaped to receive and frictionally engage a luer-type male slip-fit connector. Alternatively or additionally, the exterior surface of the structure 104 or conduit 104 can be sized and shaped to receive and frictionally engage a luer-type female slip-fit connector. According to the present application, such an arrangement can enable a standard conduit 50 (e.g., a standard or commonly available intravenous tube, intravenous connector, saline bag, etc.) to be used as part of the fluid system 16.

[0163] Referring to Figure 15 In selected embodiments, an alternative method 108 for cleaning, removing a wound, and / or debriding a wound bed can be initiated when the device 10 is configured 60 for use. Configuring 60 the device 10 for use can include selecting a device 10 having an appropriate contact surface 36, opening a package containing the device 10, and installing a reservoir 44 (e.g., selecting a saline bulb, removing a cap from the saline bulb, inserting the outlet 88 of the saline bulb into the rear portion 78b of the aperture 78 of the head 14). Thereafter, the device 10 can be moved to position 64 the contact surface 36 proximate the wound bed.

[0164] To begin cleaning, debriding, and / or debridement, the user can manually squeeze 66 the reservoir 44 to create a flow of fluid to the contact surface 36 and / or place 68 the contact surface 36 in contact with the wound bed. Thereafter, the user can move 70 the contact surface 36 over the wound bed. Moving 70 the contact surface 36 relative to the wound bed in combination with the flushing effect created by the fluid can tend to clean, remove, and / or debride the wound bed. The movement 70 of the contact surface can be side-to-side, back-and-forth, at an angle, in small circles, etc., or combinations or portions thereof. Thus, the user can continue to dispense 66 fluid, apply 68 the contact surface 36 to the wound bed, and move 70 the contact surface 36 over the wound bed until it is determined 72 that cleaning, debriding, and / or debridement is complete. Once complete, the device 10 can be discarded 110.

[0165] Reference is made to Figure 16 In selected embodiments, another alternative method 112 for cleaning, debriding, and / or debridement of a wound bed can begin when the device 10 is configured 60 for use. Configuring 60 the device 10 for use can include removing the device from a sterile package. To begin cleaning, debriding, and / or debridement, the user can manually place 68 the contact surface 36 in contact with the wound bed. Thereafter, the user can move 70 the contact surface 36 over the wound bed. Moving 70 the contact surface 36 relative to the wound bed can tend to clean, remove, and / or debride the wound bed. If a finger (e.g., index finger) is used to guide the device 10 or the head 14 of the device 10, the user can selectively vary the pressure and / or orientation of the head 14 relative to the wound bed to more precisely control the outcome of the procedure. Thus, the user can continue to apply 68 the contact surface 36 to the wound bed and move 70 the contact surface 36 over the wound bed until it is determined 72 that cleaning, debriding, and / or debridement is complete. Once complete, the device 10 can be discarded 110.

[0166] In certain embodiments, the method 112 can precede the application of fluid, etc., to the wound bed. Thus, the method 112 can benefit from the fluid without requiring the fluid to be applied at the same time as the contact surface 36 is placed 68 in contact with the wound bed or as the contact surface 36 is moved 70 over the wound bed.

[0167] In other embodiments, a combination of the two methods 108, 112 can be used to treat a wound in one session. For example, for a first period of time, the user can employ the various steps 64, 66, 68, 70 corresponding to the "wet" method 108, then remove the reservoir 44 (e.g., remove the saline cartridge located within the recess 90) and transition to employing the various steps 68, 70 corresponding to the "dry" method 112, with a finger placed within the recess 90 to provide greater control of the force, orientation, etc. of the device 10. This hybrid method can end by using the fluid remaining in the reservoir 44 to flush or wash the wound bed.

[0168] Referring to Figures 17-31 Different wounds can fall at different locations in the wound infection continuum. Thus, different wounds can require different treatment. For example, in some cases, the wound infection continuum can be divided into multiple zones (e.g., three zones). A first zone can correspond to a lower level of infection, while one or more other zones can correspond to one or more higher levels of infection. Thus, one or more methods 58, 108, 112 according to the present application can enable wounds corresponding to the first zone to be treated differently than wounds corresponding to one or more of the other zones.

[0169] For example, if an examination of the wound bed indicates that the wound corresponds to a second zone or other higher zone of the wound infection continuum, a user (e.g., a medical professional) can select, install, and / or use a relatively aggressive contact surface 36. Conversely, if an examination of the wound bed indicates that the wound corresponds to a first zone of the wound infection continuum, the user can select, install, and / or use a less aggressive contact surface 36.

[0170] Alternatively, in one or more methods 58, 108, 112 according to the present application, a wound can be evaluated based on the presence and / or nature of devitalized tissue. For example, in some cases, a wound can be classified as one of three cases. A first case can correspond to firmly adhered devitalized tissue. A second case can correspond to loosely adhered devitalized tissue. A third case can correspond to a wound that can simply benefit from cleansing. Thus, one or more methods 58, 108, 112 according to the present application can enable wounds corresponding to the first, second, and third cases to be treated differently.

[0171] For example, if an examination of the wound bed indicates that the wound corresponds to firmly adhered devitalized tissue, a user can select, install, and / or use a relatively aggressive contact surface 36. Such a contact surface 36 can be referred to as a debriding surface 36a. If an examination of the wound bed indicates that the wound corresponds to loosely adhered devitalized tissue, a user can select, install, and / or use a moderately aggressive contact surface 36. Such a contact surface 36 can be referred to as a decorticating surface 36b. If an examination of the wound bed indicates that the wound can simply benefit from cleansing, a user can select, install, and / or use a non-aggressive contact surface 36. Such a contact surface 36 can be referred to as a cleansing surface 36c.

[0172] The contact surfaces 36 according to the present application can have any suitable configuration. Generally, increasing the sharpness and / or number of edges of the various extensions 82 of the contact surfaces 36 can produce a more aggressive effect when applied to a wound bed. Thus, the cleaning surfaces 36c can have few sharp edges, if any, the debriding surfaces 36b can have a moderate number of edges and / or edges of moderate sharpness, and the debridement surfaces 36a can have a large number of edges and / or edges of increased sharpness.

[0173] Figures 17-23 One embodiment of a simplified body 12 and head 14 combination is shown, wherein the head 14 includes (e.g., is integrally formed or molded to have) a cleaning surface 36c.

[0174] Figures 24-27 One embodiment of a simplified body 12 and head 14 combination is shown, wherein the head 14 includes (e.g., is integrally formed or molded to have) a debriding surface 36b.

[0175] Figures 28-31 One embodiment of a simplified body 12 and head 14 combination is shown, wherein the head 14 includes (e.g., is integrally formed or molded to have) a debridement surface 36a. In selected embodiments, the extensions 82 of the contact surfaces 36 (e.g., the debridement surfaces 36a) can alternate in height or laterally offset. For example, as shown, the two most distal and two most proximal extensions 82 can be oriented such that their highest portions are laterally outboard for better cutting at the apex of the head 14, but the extensions 82 can alternate in other ways to create a wider cutting path. Figure 28

[0176] Referring Figures 32-38 In selected embodiments, the simplified body 12 and head 14 combination can be formed without the apertures 78 for fluid passage through the head 14. Instead, the combination can include one or more ribs 114 that extend to connect and / or reinforce the base 80 of the head 14 relative to the body 12 or handle portion 12. In certain embodiments, such ribs 114 can include a proximal end 102 having a curved surface 106 formed therein that approximates or replicates a portion of a fingertip curve. Thus, the one or more ribs 114 can be configured to engage a user's fingertip.

[0177] In selected embodiments, the head 14 can include a base 80 without any extensions 82 projecting from the base. For example, as shown, Figures 32-38 ​As shown, the front face 40 of the base 80 can be substantially flat. Such a flat surface can provide a location for adhering a contact surface 36, including a scrub pad (e.g., an open cell foam, a closed cell foam, a soft silicone, or other semi-abrasive surface). Alternatively, the base 80 can provide a location or structure to which an appropriate contact surface 36 can be fastened, snapped, slid over both ends of the base 80, or otherwise secured to the head 14. Thus, the body 12 can be provided in a non-sterile condition and still be safely used when a sterile contact surface 36 is secured in place. Thus, in such embodiments, the contact surface 36 can include or be formed from a scrub pad or the like of a different material than that forming the head 14 or the head 14 and body 12.

[0178] Referring to Figures 39-45 In selected embodiments, the simplified body 12 and head 14 combination can be formed with a base 80 that includes a wedge 116, a ramp 116, a crescent 116, or the like that provides a user's fingertips with a place to rest. Thus, there are a variety of ways in which the base 80 can be configured to engage a user's fingertips.

[0179] Referring to Figures 46-52 An alternative embodiment of the simplified body 12 and head 14 combination is illustrated. As shown, the head 14 can include (e.g., can be integrally formed or molded to have) a debridement surface 36a. In selected embodiments, the extension 82 of the contact surface 36 (e.g., the debridement surface 36a) can face outward (i.e., have a highest portion along the outer edge) so that the outer edge of the head 14 can better engage and cut into tissue that needs to be debrided. Further, when the head 14 is engaged with a wound bed, the head 14 can be manipulated to pull along its outer edge to form a sharper debrided wound edge as can be desired by a medical professional using the device 10 or supervising its use. For example, the head 14 can be manipulated with a dicing motion along its edge to enable a medical professional to maximize control over the aggressiveness of the debridement achieved during the procedure.

[0180] In selected embodiments, the device 10 (e.g., the body 12 and / or head 14) according to the present application can have a number 118, a letter 118, a marking 118, a symbol 118, a color code 118, or the like applied thereto that indicates where the corresponding contact surface 36 falls on a scale of aggressiveness. For example, within a scale of numbers from one to four, the number one marking 118 can indicate a clean surface 36c or some other least aggressive surface 36, while the number four marking 118 can indicate a sharp debridement surface 36a or some other most aggressive surface 36. Thus, a medical professional or other user can refer to the number 118 or the like when selecting a device 10 to use.

[0181] Reference is made to Figures 53-61 In selected embodiments, the aperture 78 can be omitted from the detachable head 14 of the device 10 according to the present application. In such embodiments, the frame 34 of the head 14 can still include the aperture 76 to support attachment to the body 12. The shape and size of such aperture 76 can be designed to selectively receive the physical linkage 28, horn 28, etc. that conducts the vibration, oscillation, and / or reciprocating motion from the body 12 to the head 14.

[0182] Reference is made to Figures 62-72 In selected embodiments, the fluid system 16 can be separate from (e.g., positioned somewhat remotely relative to) the body 12 and / or head 14. For example, the fluid system 16 can include a pump (e.g., a peristaltic pump) that draws fluid from a reservoir 44 (e.g., a saline bag) and pushes the fluid through a relatively long conduit 50a to the aperture 78 in the head 14. In this manner, the flow of liquid to the head 14 can be controlled (e.g., finely controlled) and can be set to a relatively low flow rate to avoid agitation, liquid control, or liquid absorption issues for the user and / or patient. In such embodiments, the body 12 can provide a channel 120 for receiving and engaging the conduit 50a. The channel 120 can cradle the conduit 50a and ensure that the conduit 50a moves with the body 12 and does not inadvertently pull away or detach from the head 14.

[0183] In certain embodiments, the body 12 and / or head 14 that are configured for use with a remote reservoir 44 can also be configured for use with an on-board or attached reservoir 44. For example, the body 12 can be shaped to house, extend, or support at least a portion of the reservoir 44 (e.g., at least a portion of a saline balloon). In such arrangements, the channel 120 can receive and secure a relatively short conduit 50b. Insertion of the outlet 88 of the reservoir 44 into one end of the relatively short conduit 50b can secure or connect the reservoir 44 to the remainder of the device 10.

[0184] Reference is made to Figures 73-88In selected embodiments, head 14 can be configured for open deep wounds or for damaged areas or tunneling wound care situations. Accordingly, the size, shape, and length of contact surface 36 and frame 34 for such embodiments can be designed to be sufficient to support or facilitate this functionality. In certain embodiments, such a "deep pocket" type head 14 can have a hole 76 to support securement to body 12. The shape and size of such hole 76 can be designed to selectively receive physical linkage 28, horn 28, etc. that conduct vibration, oscillation, and / or reciprocating motion from body 12 to head 14. In other embodiments, the deep pocket type head 14 can be integrally connected to (e.g., molded as a single unit with) body 12 or handle portion 12 that is shaped to support a user's fingers or reservoir 44 as described above.

[0185] Referring to Figure 89 and 90 In selected embodiments, wound care device 10 according to the present application can be used in certain alternative methods 122. Such alternative methods 122 can be performed as standalone wound care methods or can be incorporated into one or more other methods described above (e.g., between steps 72 and 74 in method 58 of Figure 5 , between steps 72 and 110 in method 108 of Figure 15 , between steps 72 and 110 in method 112 of Figure 16 , etc.). In certain embodiments, one or more alternative methods 122 can involve applying an antiseptic and / or anti-biofilm gel, paste, powder, etc. to the wound bed. This can help to physically break down any biofilm (e.g., disrupt the additional polymeric substance (EPS) of the biofilm), while also actively working to (1) expose, lift, wash away, and / or kill bacteria, and / or (2) chemically disrupt the biofilm.

[0186] For example, in one alternative method 122a, an antiseptic and / or anti-biofilm material (e.g., a gel, paste, powder, etc.) can be applied 124 to the wound bed. Thereafter, wound care device 10 according to the present application can be used to scrub 126 the material into the wound bed. The material can be left 128 in place for a limited period of time (e.g., a period of time ranging from about 1 minute to about 15 minutes), and then rinsed 130 away. Thereafter, if desired or necessary, an ointment can be applied 132.

[0187] If the antiseptic and / or antibiofilm material has properties that are beneficial and not potentially harmful for long-term application to or exposure on a wound bed, then a different approach 122b can be used. Specifically, after the material is applied 124 and swabbed 126, it can be left 134 in place for an extended period of time. For example, in the case of an acutely infected wound, the material can be left 134 in place for hours to days (e.g., up to 7 days). Thus, the antiseptic and / or antibiofilm material can positively work to prevent bacterial growth, biofilm regrowth, and provide a properly moist wound healing environment for an extended period of time.

[0188] Examples of antiseptic and / or antibiofilm materials that can be rinsed 130 off after a few minutes in selected embodiments can be hypochlorous acid, iodine, polyhexamethylene biguanide (PHMB), and the like. In certain embodiments, a preferred material can combine one or more antiseptics and / or antibiotics with one or more surfactants. Surfactants can break down the protective outer layer of bacteria and / or viruses, kill bacteria or viruses, bind to dead or live bacteria and lift them off the wound bed, and the like. Thus, in one or more methods 58, 108, 112, 122 according to the present application, one or more surfactants can be a valuable contributor to a gel, paste, powder, and the like applied to a wound bed.

[0189] EDTA is a metal chelator that can help break down biofilm and work well in combination with one or more surfactants. In one or more methods 58, 108, 112, 122 according to the present application, adding EDTA to a combination of antiseptics such as iodine and PHMB can result in or make suitable a liquid material (e.g., an emulsified gel) for application to a wound bed (i.e., when combined with manual and / or low frequency electromechanical operation of a wound care device 10 to a wound bed).

[0190] Examples of antiseptic and / or antibiofilm materials that can be left 134 in place for a longer time can be a slow release iodine ointment, a PHMB ointment, or a combination or partial combination of iodine, PHMB, EDTA, one or more surfactants, and the like. If such a combination is made in the case of a viscous gel or paste, it can be applied to the contact surface 36 of the head 14 and then swabbed into the wound bed to break down biofilm bacteria and EPS and kill bacteria.

[0191] Reference is made to Figure 91 and 92In selected embodiments, certain heads 14 according to the present application can include cutting elements 136 (e.g., spatulas 136a, scalpels 136b, etc.) instead of contact surfaces 36. For example, heads 14 can be configured as detachable heads 14 having apertures 76 for receiving horns 28 and the like therein. Thus, when such heads 14 are applied to horns 28 and the corresponding devices 10 are "turned on," motion generator 18 can cause cutting elements 136 to vibrate, oscillate, and / or reciprocate at a desired frequency. This motion can enable a user to more easily or in a more controlled manner remove dead tissue, callus material, and the like.

[0192] In view of the foregoing, devices 10 according to the present application can be equipped or simply fitted with a variety of different heads 14 (e.g., one or more cleaning heads 14, one or more debriding heads, one or more debridement heads 14, one or more cutting heads 14, and the like or combinations or sub-combinations thereof). Thus, a user can select and install a particular head 14 to perform a particular task. When that task is complete, the user can remove that head 14 and install a different head 14 to perform a different task.

[0193] Reference is made to Figures 93-95 In selected embodiments, certain heads 14 according to the present application can include cutting elements 136 (e.g., spatulas 136a, scalpels 136b, etc.) in addition to contact surfaces 36. For example, heads 14 can be configured to receive and retain detachable cutting elements 136. Thus, when such heads 14 are applied to horns 28 and the corresponding devices 10 are "turned on," motion generator 18 can cause detachable cutting elements 136 to vibrate, oscillate, and / or reciprocate at a desired frequency.

[0194] In selected embodiments, engagement mechanisms 138 can selectively and / or detachably secure cutting elements 136 to the remainder of heads 14. For example, the main portion of heads 14 can include one or more recesses 140, and engagement mechanisms 138 can include one or more extensions 142 shaped to engage one or more recesses 140. Pliers "jaws" 144 and the like can be manually bent to sufficiently open engagement mechanisms 138 so that they can engage the remainder of heads 14 (e.g., so that one or more extensions 142 can be positioned to align with one or more recesses 140). When the manual bending of engagement mechanisms 138 is complete, engagement mechanisms 138 can return to a closed position in which their pliers jaws 144 are in an intermediate and / or undeflected position. The tendency of engagement mechanisms 138 to remain in the closed position can retain one or more extensions 142 within one or more recesses 140, thereby selectively and / or detachably securing cutting elements 136 to the remainder of heads 14.

[0195] Reference is made toFigures 96-99 In selected embodiments, the engagement mechanism 138 can be selectively and / or removably secured within a hole 146 formed in the main portion of the head 14. For example, the main portion of the head 14 can include a tapered hole 146 and the engagement mechanism 138 can include a tapered shaft 148 shaped to engage the tapered hole 146. The frictional engagement between the tapered hole 146 and the tapered shaft 148 of the engagement mechanism 138 can be sufficient to secure the cutting element 136 to the remainder of the head 14.

[0196] In certain embodiments, an axis of symmetry 150 can exist between the tapered shaft 148 and the tapered hole 146. Accordingly, a user can select a desired orientation for the corresponding cutting element 136 prior to inserting the engagement mechanism 138 into the tapered hole 146 of the head 14. Once the orientation is selected and the tapered shaft 148 is within the tapered hole 146, the frictional engagement between the two components 146, 148 can resist relative rotation of one component with respect to the other about the axis of symmetry 150.

[0197] In selected embodiments, a kit or system according to the present application can include a removable cover 152 for the cutting element 136. The removable cover 152 can protect the user and / or the patient from inadvertently or unnecessarily contacting the cutting element 136 prior to the user being ready to use the cutting element 136. Alternatively or additionally, the cover 152 can maintain the sterility of the cutting element 136 prior to use.

[0198] Referring to Figures 100-102 In selected embodiments, the simplified body 12 and head 14 combination can include a cutting element 136 (e.g., a spatula 136a, a scalpel 136b, etc.) in addition to the contact surface 36. In such embodiments, the engagement mechanism 138 can selectively and / or removably secure the cutting element 136 to the remainder of the head 14. For example, the main portion of the head 14 can include a rail 154 and the engagement mechanism 138 can include a hole 156 shaped to engage the rail 154. When the hole 156 is slid onto the rail 154, the engagement mechanism 138 can frictionally and / or mechanically engage the rail 154, thereby selectively and / or removably securing the cutting element 136 to the remainder of the head 14.

[0199] Referring to Figure 103 and 104In some embodiments, the wound care device 10 can enable a standard catheter 50 (e.g., a standard or common intravenous tube, intravenous connector, saline bag, etc.) to be used as part of the fluid system 16 according to the present application. For example, in certain embodiments, a kit corresponding to the wound care device 10 can include an adapter 158. The adapter 158 can interface between the aperture 78 (e.g., the aperture 78 adapted to receive the outlet 88 of a saline bulb) and a standard connector 160 (e.g., a luer-type connector). That is, one end of the adapter 158 can be sized and shaped to be inserted into and frictionally engage the aperture 78 in the head, while the opposite second end can be sized and shaped to receive and frictionally or mechanically engage a standard connector.

It should be noted that many of the functions described in the blocks can not be performed in the order shown in the figures. In some alternative implementations, the functions described in the blocks can be performed in a different order, or some of the blocks can be performed concurrently, or with prior blocks or subsequent blocks. Alternatively, some of the blocks can be omitted, or some of the blocks can be performed at least in part by one or more other devices or components not explicitly shown in the figures.

[0201] Reference throughout this specification to "one embodiment", "an embodiment", "certain embodiments", "some embodiments", etc., means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrase "in one embodiment" or "in an embodiment" or "in certain embodiments" or "in some embodiments" in various places throughout this specification are not necessarily referring to the same embodiment. Furthermore, the particular features, structures, or characteristics can be combined in any suitable manner on one or more embodiments.
