Description

[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to U.S. Provisional Application No. 63 / 028,819, filed May 22, 2020, and entitled "SYSTEM, METHOD, AND DEVICE UTILIZING REVERSIBLE CONNECTOR." The disclosure of the priority application is incorporated herein by reference in its entirety.

[0002] FIELD OF THE INVENTION Aspects of the present disclosure relate to systems, methods, and devices for inflating a compression garment from a fluid source connected via a reversible connector that provides unidirectional fluid flow through multiple fluid channels when the reversible connector is connected in either a first orientation or a second orientation. [Background technology]

[0003] The vascular compression system includes a compression garment fluidly connected to a fluid source for cyclically inflating the compression garment when the compression garment is worn on a patient's limb. The cyclic inflation of the compression garment increases blood circulation and reduces the likelihood of deep vein thrombosis (DVT). A controller controls operation of the fluid source to deliver fluid, e.g., air, to a bladder of the compression garment to create a bladder pressure gradient along the compression garment, thereby moving blood in a desired direction.

[0004] In conventional vascular compression systems, a controller provides fluid, e.g., air, to the compression garment through tubing, which may include, for example, three separate tubes. Typically, a connector connects the tubing extending from the controller (i.e., controller tubing) to the tubing extending from the compression garment (i.e., garment tubing). The garment tubing provides fluid to multiple bladders (e.g., two, three, four, or more) of the compression garment. In the case of three bladders, for example, the three bladders may include a distal bladder positioned around the wearer's ankle, an intermediate bladder positioned around the wearer's calf, and a proximal bladder positioned around the wearer's thigh. Due to the proximity of the three tubes in the tubing, the connector must be appropriately sized to allow the passage of fluid, e.g., air, and to limit separation of the three tubes. Typically, the three tubes of the tubing are joined together side-by-side. Conventional connectors used to connect the controller tubing to the garment tubing can only be connected in a single orientation. In some implementations, the connector may be unable to connect in more than one orientation or may be unable to provide a fluid connection to all three tubes when connected in a second orientation, which may lead to improper functioning of the compression system and / or may cause harm or discomfort to the patient. Thus, a need exists in the art for a connector that connects all tubes (e.g., two, three, four or more) of the controller tubing and garment tubing in more than one orientation (e.g., straight and reverse orientation), while providing fluid flow in a single direction from the controller fluid source to the compression garment regardless of connection orientation, thereby ensuring proper functioning of the compression system and avoiding potential discomfort or harm to the patient. Summary of the Invention

[0005] Aspects of the present disclosure include a compression garment selectively engageable and operable by a controller for inflation via a reversible connector. The compression garment includes a plurality of bladders and a plurality of garment ties in fluid communication with the plurality of bladders at a first compression garment tubing end. The garment tubing includes a compression garment tubing having a plurality of controller tubes. A second compression garment tubing end is provided opposite the first compression garment tubing end, and a first connector portion is located at the second compression garment tubing end. The controller controls communication with a source of fluid flow and includes controller tubing having a plurality of controller tubes selectively communicating with the source of fluid flow at the first controller tubing end. The controller tubing also includes a second controller tubing end opposite the first controller tubing end and a second connector portion located at the second controller tubing end. The first connector portion of the garment tubing and the second connector portion of the controller tubing are selectively reversibly connectable together to form a reversible connector. A plurality of fluid flow passages extend through each of the first connector portion and the second connector portion to form a first fluid flow passage when the first connector portion is coupled to the second connector portion in a first orientation. The plurality of fluid flow passages in the first connector portion and the second connector portion cooperate to form a second fluid flow channel when the first connector portion is coupled to the second connector portion in the second orientation. Fluid flow between a first controller tube of the plurality of controller tubes and a first compression garment tube of the plurality of compression garment tubes is communicated in a first fluid flow direction via the first fluid flow channel when the first connector portion and the second connector portion are connected in the first orientation. Fluid flow through a first compression garment tube of the plurality of compression garment tubes and a first controller tube of the plurality of controller tubes is communicated in the first fluid flow direction via the second fluid flow channel when the first connector portion and the second connector portion are connected in the second orientation.

DETAILED DESCRIPTION OF THE INVENTION

[0011] Various aspects will now be described in more detail with reference to the drawings. In the following description, for purposes of explanation, numerous specific details are set forth in order to provide a thorough understanding of one or more aspects. However, it may be apparent that such aspects may be practiced without these specific details. Additionally, the term "component" as used herein may be one of the parts that make up a system, may be hardware, firmware, and / or software stored on a computer-readable medium, and may be divided into other components.

[0012] The following description provides examples and is not intended to limit the scope, applicability, or embodiments set forth in the claims. Changes may be made in the function and arrangement of the elements discussed without departing from the scope of the present disclosure. Various embodiments may omit, substitute, or add various procedures or components as appropriate. For example, methods described may be performed in an order different from that described, and various steps may be added, omitted, or combined. Also, features described with respect to some embodiments may be combined in other embodiments.

[0013] The term reversible is used throughout this disclosure as a modifier for a connector or set of connectors. For context, examples of the term reversible connector include a connector or set of connectors that can be connected in at least two different orientations (e.g., "flipped" or rotated 180 degrees about an axis) without affecting the inflation sequence of the bladders in the compression garment. The foregoing examples are in contrast to non-reversible connectors, where reversing the connection orientation (e.g., rotating the connector 180 degrees about an axis) affects the inflation sequence of the bladders in the compression garment.

[0014] Referring to the figures, wherein like reference numerals refer to like components, FIG. 1 illustrates an exemplary compression system 100, various features of which may be used in accordance with aspects of the present disclosure, including a controller 102, a compression garment 104, and one or more reversible connectors 120. As shown in FIG. 1, the compression garment 104 includes a sleeve The compression garment 104 may be connected to the controller 102 by directly connecting the first reversible connector portion 110a on the controller side to the first reversible connector portion 108a on the controller side, or by connecting the two aforementioned connector portions to an extension or adapter 119. The extension or adapter 119 may provide additional distance between the controller 102 and the compression garment 104 and / or may accommodate different connectors (e.g., having different engagement mechanisms for fluid path configurations) on either or both the controller 102 and / or the compression garment 104. Throughout this disclosure, the terms adapter and extension may be used interchangeably. In one example, the extension 119 may include, for example, a first reversible connector portion 108b on one end thereof and a second reversible connector portion 110b on a second end thereof, with connecting tubing 112c providing a fluid connection between the two connector portions. The first reversible connector portion 108b and the second reversible connector portion 110b may be similar to, for example, the controller-side reversible first connector portion 108a and the sleeve-side reversible second connector portion 110a, respectively. Furthermore, while specific examples of connections of the compression garment 104, controller 102, and / or adapter 119 are shown, one skilled in the art will understand that any of the connector portions or connection mechanisms described throughout this specification may be used in any known method or configuration of connecting the controller 102 to the compression garment 104. Furthermore, any one or combination of the controller-side reversible first connector portion 108a, sleeve-side reversible second connector portion 110a, first reversible connector portion 108b, and / or second reversible connector portion 110b may be referred to interchangeably throughout this disclosure simply as the first connector portion or the second connector portion.

[0015] 1 illustrates one embodiment of a first connector portion 108 and a second connector portion 110 shown in an uncoupled configuration, and a compression garment 104. The compression garment 104 is configured to apply continuous compression therapy to a limb of a wearer, such as a medical patient in need of compression therapy, and a controller 102, having one or more processors and / or pumps or fluid sources, is configured to control the operation of the compression garment 104. The compression garment 104 may include multiple bladders capable of containing a fluid, such as air. For example, the compression garment 104 may include a distal inflatable bladder 106a, an intermediate inflatable bladder 106b, and a proximal inflatable bladder 106c. Although three bladders are referenced herein, it will be apparent that fewer or more bladders may be used, e.g., one, two, or four, and as described in more detail below, a reversible connector 120 according to various aspects of the present disclosure is configured to operably engage and couple the compression garment 104 to the controller 102, regardless of whether the compression garment includes only one inflatable bladder 106a, 106b, 106c, or two or more inflatable bladders 106a, 106b, 106c. The compression garment 104 may be secured around the wearer's limb (e.g., using hook-and-loop fasteners or straps, among other types of securing mechanisms) and may be adjustable to fit around limbs of different sizes / circumferences.

[0016] In some embodiments, the controller 102 may include a pump or other fluid source to control the operation of the compression garment 104 to perform compression cycles in which the inflatable bladders 106a, 106b, 106c are inflated to apply pressure to the wearer's limb and establish a pressure gradient applied to the limb by controlling the fluid in the inflatable bladders 106a, 106b, 106c of the compression garment 104 during one or more compression cycles. For purposes of describing an exemplary operation of the compression system 100, each compression cycle may be followed by a venting cycle in which pressure in each of the inflatable bladders 106a, 106b, 106c is released. The compression and venting cycles together form one complete treatment cycle of the compression system 100. The compression system 100 may measure the pressure gradient applied by the inflatable bladders 106a, 106b, 106c and may make adjustments based on this measured pressure gradient. In some embodiments, the compression system 100 may not measure the pressure gradient. and / or may not adjust the pressure gradient based on measurements during operation of the compression system 100. Rather, the compression system 100 may inflate and / or deflate the bladder of the compression garment 104.

[0017] The compression garment 104 may be a thigh-length sleeve positionable around the wearer's leg, with a distal inflatable bladder 106a positionable around the wearer's ankle, an intermediate inflatable bladder 106b positionable around the wearer's calf, and a proximal inflatable bladder 106c positionable around the wearer's thigh. The inflatable bladders 106a, 106b, 106c may expand and contract under the influence of fluid (e.g., air or other fluid) delivered from a pressurized fluid source via the controller 102. The controller 102 may deliver pressurized fluid from the fluid source to the inflatable bladders 106a, 106b, 106c. A pressurized fluid source may deliver pressurized fluid to inflatable bladders 106a, 106b, 106c through a controller-side reversible first connector portion 108a, which is connected to controller 102 via controller tubing 112a and / or may form part of the controller body (e.g., as depicted in Figures 9q-9s), reversible connector 120, and compression garment tubing 112b. As described in further detail below, reversible connector 120 may include a monitor-side first connector portion 108a and a compression garment-side second connector portion 110a, and / or may include an adapter 119 having first reversible connector portion 108b, second reversible connector portion 110b, and connecting tubing 112c. The first connector portion 108 may be coupled to an end of the controller tubing 112a (the other end of which is coupled to the controller 102), and the second connector portion 110 may be coupled to an end of the compression garment tubing 112b (the other end of which is coupled to the compression garment 104). While FIG. 1 shows only a single first connector portion 108 and second connector portion 110, embodiments of the present disclosure can be used with extension tubing sets (e.g., lengths of tubing with connectors on either end) and / or adapters (e.g., lengths of tubing with a first type of connector on a first end and a second type of connector on a second end). Some non-limiting examples of adapters are described with respect to FIGS. 17 and 18 below.Additionally, although hidden in Figure 1, any one or combination of the connectors described herein may be used to provide a controller-side connection between the controller 102 and any one or combination of the adapter, extension tubing set, and / or compression garment 104. Some examples of controller-side connections are described in further detail below with respect to Figures 9q-9s.

[0018] 2a shows a cross section of exemplary tubing 212 that may be utilized between a fluid source controlled by a controller and a compression sleeve according to embodiments of the present disclosure. In a non-coupled configuration, tubing 212 may be similar to controller tubing 112a and compression garment tubing 112b shown in FIG. 1 and may include three separate tubes or tubing passages or conduits 222a, 222b, and 222c (such tubes, passages, or conduits are interchangeably referred to herein as "tubes"), a separate tube for each of the inflatable bladders 106a, 106b, and 106c of the compression garment 104 shown in FIG. 1. In some embodiments, tubing 212 may be smooth tubing, for example, with three separate tubes 222a, 222b, and 222c housed within tubing 212 formed as a single piece. In other embodiments, tubing 212 may comprise three separate tubes 222a, 222b, and 222c, each formed as a separate piece. The tubing 212 may be flexible. The tubing 212 may be made of polyvinyl chloride (PVC), polyurethane, or the compression garment 1 shown in FIG. 2. As described in more detail below, reversible connector 120 according to various aspects of the present disclosure may be constructed such that tubing 212 includes three separate tubes 222a, 222b, 222c, as shown in FIG. 2, or may include more or fewer separate tubes 222a, 222b, 222c, e.g., a single tube. The compression garment 104, whether including one tube (not shown), two tubes (not shown), or four or more tubes (not shown), is configured to operably engage and couple to the controller 102.

[0019] FIG. 2b shows a cross-section of another exemplary implementation of tubing 213 that may be utilized between a fluid source controlled by a controller and a compression garment according to embodiments of the present disclosure. Any one or any combination of the tubing profiles shown in FIGS. 2a and / or 2b may be implemented to create a fluid path between each of the connectors and / or sleeves (e.g., sleeve 100 of FIG. 1 ) and / or controllers (e.g., controller 102 of FIG. 1 ). For example, tubing 212 may be used as controller tubing 112a and compression garment tubing 112b shown in FIG. 1 . Tubing 213 may be flexible. Tubing 213 may be made from polyvinyl chloride (PVC), polyurethane, or any suitable material for delivering fluid to the compression garment 104 shown in FIG. 1 . In preferred embodiments, the material of tubing 213 may be flexible or semi-flexible while maintaining sufficient rigidity to prevent kinking or pinching of the tube (thereby blocking fluid flow). The tubing 213 may include three separate tube or tubing passages or conduits 223a, 223b, and 223c that correspond to and create a fluid path between a controller (e.g., controller 102 of FIG. 1 ) and the three bladders 106a, 106b, and 106c of the compression garment 104. While three tube or tubing passages or conduits 223a, 223b, and 223c are shown, and three bladders are provided as an example, embodiments of the present disclosure may include more or fewer passages corresponding to the number of inflatable bladders. For example, the tubing may include two passages providing fluid communication to two bladders, or may include four or more passages providing fluid communication to a corresponding number of bladders. For example, the tubing may include four to six passages in one exemplary implementation. In one variation, tubing 213 may have a configuration as shown in FIG. 2b, for example, to create a fluid pathway between any one or combination of the connectors, compression garment 104, and / or controller 102 described throughout this disclosure. In some embodiments, tubing 212 may be similar to the tubing described above with respect to FIG. 2a, but may include an additional alignment section 221. The alignment portion may include an additional passageway or alignment mechanism, for example, comprising first alignment portion 224 and second alignment portion 225.One function of alignment section 221 may be to ensure that tubing 213 is installed in the correct orientation (e.g., not "inverted") with respect to any one of the connectors described throughout this disclosure. One exemplary implementation of alignment section 221 and its interaction with the corresponding portion of the connector (e.g., during assembly of the tubing and connector) is described below with respect to Figures 10 and 11.

[0020] 2c shows a cross section of exemplary tubing 214 that may be utilized between a fluid source controlled by a controller and a compression sleeve according to embodiments of the present disclosure. In a non-coupled configuration, tubing 214 may be similar to controller tubing 112a and compression garment tubing 112b shown in FIG. 1 and may include three separate tubes or tubing passages or conduits 224a, 224b, and 224c (such tubes, passages, or conduits are interchangeably referred to herein as "tubes"), a separate tube for each of the inflatable bladders 106a, 106b, and 106c of the compression garment 104 shown in FIG. 1. In some embodiments, tubing 212 may be smooth tubing, with, for example, three separate tubes 224a, 224b, and 224c housed in tubing 214 formed as a single piece. In other embodiments, tubing 212 may comprise three separate tubes 224a, 224b, and 224c, each formed as a separate piece. The tubing 214 may be flexible. The tubing 214 may be made from polyvinyl chloride (PVC), polyurethane, or any suitable material for delivering fluid to the compression garment 104 shown in FIG. 1. In a preferred embodiment, the material of the tubing 214 may be flexible or semi-flexible, while maintaining sufficient stiffness to prevent the tubing from kinking or pinching (thereby blocking fluid flow). In one embodiment, the tubing 214 is flexible. or may be formed by extruding or molding a semi-flexible material. As described in more detail below, the reversible connector 120 according to various aspects of the present disclosure is configured to operably engage and couple the compression garment 104 to the controller 102, regardless of whether the tubing 212 includes three separate tubes 222a, 222b, 222c as shown in FIG. 2a, 223a, 223b, 223c as shown in FIG. 2b, and 224a, 224b, 224c as shown in FIG. 2c, or more / fewer separate tubes 224a, 224b, 224c, e.g., a single tube (not shown), two tubes (not shown), or four or more tubes (not shown).

[0021] FIG. 3 a illustrates an exemplary reversible connector 320 having a first connector portion 308 and a second connector portion 310 (also referred to herein interchangeably as “connector components” or “connector portions”) in a connected configuration (such connected configuration is also referred to herein interchangeably as an “engaged” or “coupled” configuration) according to an embodiment of the present disclosure. The first connector portion 308 and the second connector portion 310 may be similar to the first connector portion 108 and the second connector portion 110 shown in FIG. 1 . It will be appreciated that the first connector portion 308 and the second connector portion 310 may be connected via different types of engagement mechanisms, including mechanisms for providing a slidable engagement, a compression fit, a snap fit, and a magnetic engagement, among other types of engagement. Additional examples of engagement mechanisms are described below with respect to FIGS. 5-9s, 12a-13b, and 15a-15b.

[0022] 3b, first connector portion 308 can include outer concentric wall 306a, intermediate concentric wall 304a, and inner concentric wall 314a. Inner concentric wall 314a can be positioned within intermediate concentric wall 304a, which can be positioned within outer concentric wall 306a of first connector portion 308.

[0023] 3c, second connector portion 310 can include outer concentric wall 306b, intermediate concentric wall 304b, and inner concentric wall 314b. Inner concentric wall 314b can be positioned within intermediate concentric wall 304b, which can be positioned within outer concentric wall 306b of second connector portion 310.

[0024] In some embodiments, the outer concentric wall 306 a, the intermediate concentric wall 304 a, and the inner concentric wall 314 a of the first connector portion 308 shown in FIG. 3 b can be adapted (i.e., sized) to engage with the outer concentric wall 306 b, the intermediate concentric wall 304 b, and the inner concentric wall 314 b of the second connector portion 310 shown in FIG. 3 c to form the reversible connector 320 in an engaged configuration, as illustrated in FIG. 3 a. For example, as shown in FIG. 3c, when the first connector portion 308 is engaged with the second connector portion 310 to form the reversible connector 320 in an engaged configuration, the outer concentric wall 306a of the first connector portion 308 may engage inside the outer concentric wall 306b of the second connector portion 310, the middle concentric wall 304a of the first connector portion 308 may engage inside the middle concentric wall 304b of the second connector portion 310, and the inner concentric wall 314a of the first connector portion 308 may engage inside the inner concentric wall 314b of the second connector portion 310.

[0025] In some aspects, all of the concentric walls of first connector portion 308 may be adapted such that each of the concentric walls of first connector portion 308, i.e., outer concentric wall 306 a, middle concentric wall 304 a, and inner concentric wall 314 a, engages inside a corresponding wall of second connector portion 310, i.e., outer concentric wall 306 b, middle concentric wall 304 b, and inner concentric wall 314 b. In such aspects of the present disclosure, first connector portion 308 may be a male connector portion and second connector portion 310 may be a female connector portion.

[0026] In some aspects, one or more of outer concentric wall 306 a, intermediate concentric wall 304 a, and inner concentric wall 314 a of first connector portion 308 and corresponding concentric walls, i.e., outer concentric wall 306 b, intermediate concentric wall 304 b, and inner concentric wall 314 b, of second connector portion 310, may be adapted to engage over corresponding concentric walls, i.e., outer concentric wall 306 b, intermediate concentric wall 304 b, and inner concentric wall 314 b, of second connector portion 310. In such aspects of the disclosure, there may be no male or female connector portion.

[0027] It should be noted that although Figures 3a and 3b depict the outer concentric walls 306a and 306b and the intermediate concentric walls 304a and 304b of the first and second connector portions 308, 310 as rectangular, and the inner concentric walls 314a and 314b of the first and second connector portions 308, 310 as circular in shape, aspects of the present disclosure are not limited to the configurations described in more detail herein (e.g., all walls may be rectangular, square, oval, or circular).

[0028] 3a and 3b, each of outer concentric wall 306a, intermediate concentric wall 304a, and inner concentric wall 314a of first connector portion 308 may extend from base 302a of first connector portion 308. Each of outer concentric wall 306b, intermediate concentric wall 304b, and inner concentric wall 314b of second connector portion 310 may extend from base 302b of second connector portion 310. The height of the concentric walls, i.e., the distance the concentric walls extend away from bases 302a, 302b, may be appropriately sized to form corresponding chambers 402, 404, 406 (as illustrated in FIGS. 4a and 4b) for each of the concentric walls when first connector portion 308 is engaged or connected with second connector portion 310 (e.g., via slidable engagement, press fit, snap fit, and magnetic engagement, among other types of engagement means). For example, when first connector portion 308 is slidably engaged with second connector portion 310, outer concentric wall 306a of first connector portion 308 and outer concentric wall 306b of second connector portion 310 form chamber 402 (shown in FIGS. 4a and 4b), allowing fluid, e.g., air, to pass from the first connector portion to the second connector portion. In another example, when the first connector portion 308 is slidably engaged with the second connector portion 310, the middle concentric wall 304 a of the first connector portion 308 and the middle concentric wall 304 b of the second connector portion 310 form a chamber 404 (shown in FIGS. 4 a and 4 b), allowing fluid, e.g., air, to pass from the first connector portion to the second connector portion. In yet another example, when the first connector portion 308 is slidably engaged with the second connector portion 310, the inner concentric wall 314 a of the first connector portion 308 and the inner concentric wall 314 b of the second connector portion 310 form a chamber 406 (shown in FIGS. 4 a and 4 b), allowing fluid, e.g., air, to pass from the first connector portion to the second connector portion.The height of the concentric walls can be sized such that the formed chambers 402, 404, 406 fluidly connect the first connector portion 308 with the second connector portion 310, and such that each of the formed chambers 402, 404, 406 (shown in Figures 4a and 4b) provides a seal that largely or completely prevents fluid leakage, thereby forming mutually cooperating fluid flow connecting channels.

[0029] In some embodiments, the height of the outer concentric wall 306a of the first connector portion 308 may be variable (i.e., the outer concentric wall 306a may be composed of wall sections of different heights). For example, as shown in FIG. 3b, the height of the long side of the outer concentric wall 306a may be less than the height of the short side of the outer concentric wall 306a. In some embodiments, the height of the long side of the outer concentric wall 306a may be greater than the height of the short side of the outer concentric wall 306a. The difference in height between the long side and the short side determines the height of the first connector portion 308 when the first connector portion 308 is engaged with the second connector portion 310. When forming the reversible connector 320 into an engaged configuration, greater flexibility may be possible.

[0030] 3a and 3b, in first connector portion 308, fluid flow passage 324a may be formed in intermediate concentric wall 304a, fluid flow passage 324b may be formed in intermediate concentric wall 304a, and fluid flow passage 324c may be formed by inner concentric wall 314a. In second connector portion 310, fluid flow passage 326a may be formed in intermediate concentric wall 304b, fluid flow passage 326b may be formed in intermediate concentric wall 304b, and fluid flow passage 324c may be formed by inner concentric wall 314b. One or more of the fluid flow passages 324a, 324b formed in the intermediate concentric wall 304a of the first connector portion 308 and / or one or more of the fluid flow passages 326a, 326b formed in the intermediate concentric wall 304b of the second connector portion 310 may include bump-outs 328a, 328b, 330a, 330b for directing or reflecting fluid, e.g., air, into corresponding chambers 402, 404 (shown in Figures 4a and 4b) formed by the outer concentric walls 306a, 306b and the intermediate concentric walls 304a, 304b, as described in more detail below.

[0031] 4a and 4b are top cross-sectional views of an embodiment of a reversible connector in a first orientation and a second orientation, illustrating fluid flow in each orientation. When a first connector portion 408 is mated with a second connector portion 410, each of the corresponding concentric walls forms a corresponding chamber 402, 404, 406 that allows fluid, such as air, to pass from the first connector portion 408 to the second connector portion 410. The first connector portion 408 and the second connector portion 410 are similar to the first connector portion 108 and the second connector portion 110, and the first connector portion 308 and the second connector portion 310 shown in FIGS. 1 and 3a-3c. For example, the outer concentric wall 406a of the first connector portion 408 can slide within the outer concentric wall 406b of the second connector portion 410 to form the outer chamber 402. In another example, the intermediate concentric wall 404a of the first connector portion 408 can slide into the intermediate concentric wall 404b of the second connector portion 410 to form the intermediate chamber 404. In yet another example, the inner concentric wall 414a of the first connector portion 408 can slide into the inner concentric wall 414b of the second connector portion 310 to form the inner chamber 406. The outer concentric walls 406a and 406b, the intermediate concentric walls 404a and 404b, and the inner concentric walls 414a and 414b of the first connector portion 408 and the second connector portion 410 are similar to the outer concentric walls 306a and 306b, the intermediate concentric walls 304a and 304b, and the inner concentric walls 314a and 314b of the first connector portion 308 and the second connector portion 310 shown in Figures 3b and 3c.

[0032] As illustrated in FIG. 4a, in a first orientation of the reversible connector 420 (similar to the reversible connector 120 and the reversible connector 320 shown in FIGS. 1 and 3a), when the first connector portion 408 is engaged with the second connector portion 410 in the first orientation, the outer chamber 402 may be formed by the fluid flow passages 324a, 326a that are substantially aligned with each other as shown in FIGS. 3b and 3c, the intermediate chamber 404 may be formed by the fluid flow passages 324b and 326b that are substantially aligned with each other as shown in FIGS. 3b and 3c, and the inner chamber 406 may be formed by the fluid flow passages 324c and 326c that are substantially aligned with each other as shown in FIGS. 3b and 3c. 3b and 3c, fluid flow passages 324a, 326a may be substantially aligned with adjacent bump-outs 328a, 330a to form outer chamber 402 (shown in FIG. 4a), and fluid flow passages 324b, 326b may be substantially aligned with adjacent bump-outs 328b, 330b to form middle chamber 404 (shown in FIG. 4a). This allows, in a first orientation, reversible connector 420 to connect three tubes 422a, 422b, 422c (similar to tubes 222a, 222b, 222c shown in FIG. 2a, 223a, 223b, 223c shown in FIG. 2b, and 224a, 224b, 224c shown in FIG. 2c) of controller tubing 412a (which may be similar to controller tubing 112a shown in FIG. 1). 1 ) and respectively provide fluid, e.g., air, to three tubes 422a, 422b, 422c of garment tubing 412b (similar to compression garment tubing 112b shown in FIG. 1 ). Fluid flow from the three tubes 422a, 422b, 422c of controller tubing 412a to the three respective tubes 422a, 422b, 422c of garment tubing 412b forms fluid connecting channels in the first orientation of reversible connector 420, as indicated by arrows 430a, 430b, 430c. According to another aspect of the invention, only one or two of tubes 422a, 422b, 422c of garment tubing 412b may be required, for example, for use on a compression garment with fewer than three inflatable bladders (not shown). Although shown as separate tubes in the examples of Figures 3A-4B, in an alternative embodiment, tubes 422a, 422b, and 422c may resemble any one or combination of passages 222a, 222b, and / or 222c of piping 212 of Figure 2a, and / or passages 223a, 223b, and / or 223c of piping 213 of Figure 2b, and / or passages 224a, 224b, and / or 224c of piping 214 of Figure 2c.

[0033] As illustrated in FIG. 4b, in a second orientation of the reversible connector 420 (similar to the reversible connector 120 and the reversible connector 320 shown in FIGS. 1 and 3a), when the first connector portion 408 is engaged with the second connector portion 410 in the second orientation, the outer chamber 402 may be formed by the offset fluid flow passages 324a, 326a shown in FIGS. 3b and 3c, the intermediate chamber 404 may be formed by the offset fluid flow passages 324b and 326b shown in FIGS. 3b and 3c, and the inner chamber 406 may be formed by the offset fluid flow passages 324c and 326c shown in FIGS. 3b and 3c. As shown in Figures 3b and 3c, the fluid flow passages 324a, 326a may be offset from one another and the bump-outs 328a, 330a may be offset from one another to form the outer chamber 402 (shown in Figure 4a), and the fluid flow passages 326a, 326b may be offset from one another and the bump-outs 328b, 330b may be offset from one another to form the middle chamber 404 (shown in Figure 4a). As a result, in the second orientation, the reversible connector 320 receives fluid, e.g., air, from the three tubes 422a, 422b, 422c (which may be similar to the tubes 222a, 222b, 222c shown in FIG. 2a, 223a, 223b, 223c shown in FIG. 2b, and 224a, 224b, 224c shown in FIG. 2c) of the controller tubing 412a (which may be similar to the controller tubing 112a shown in FIG. 1) and provides fluid, e.g., air, to the three tubes 422c, 422b, 422a of the garment tubing 412b (which may be similar to the compression garment tubing 112b shown in FIG. 1), respectively. Fluid flow from the three tubes 422a, 422b, 422c of the controller tubing 412a to the three respective tubes 422c, 422b, 422a of the garment tubing 412b forms fluid connection channels in the second orientation of the reversible connector 420, as indicated by arrows 430, 430b, 430c.

[0034] As illustrated in Figures 4a and 4b, the first connector portion 408 may include three inlets 416a, 416b, and 416c extending from the base 302a shown in Figure 3b, and the second connector portion 410 may include three inlets 416a, 416b, and 416c extending from the base 302b shown in Figure 3c. In the first connector portion 408, the three inlets 416a, 416b, and 416c extend from opposite ends of the base 302a shown in Figure 3b, with the concentric walls 306a, 304a, and 314a extending therefrom. In the second connector portion 410, the three inlets 418a, 418b, and 418c extend from opposite ends of the base 302b shown in Figure 3c, with the concentric walls 306b, 304b, and 314b extending therefrom. Each of the inlets 416a, 416b, 416c, 418a, 418b, 418c may be adapted to receive a corresponding tube from the piping 412a, 412b on the outer edge of the inlet 416a, 416b, 416c, 418a, 418b, 418c. Each of the three inlets 416a, 416b, 416c may be adapted to receive a corresponding tube from the controller tubing 412a, and each of the three inlets 418a, 418b, 418c may be adapted to receive a corresponding tube from the garment tubing 412b. In the first orientation, for example, each of the three inlets 416a, 416b, 416c may be adapted to receive a corresponding tube 422a, 422b, 422c, respectively, from the controller tubing 412a, and each of the three inlets 418a, 418b, 418c may be adapted to receive a corresponding tube 422a, 422b, 422c, respectively, from the garment tubing 412b. Conversely, in the second orientation, for example, each of the three inlets 416a, 416b, 416c may be adapted to receive a corresponding tube 422a, 422b, 422c, respectively, from the controller tubing 412a, and each of the three inlets 418a, 418b, 418c may be adapted to receive a corresponding tube 422c, 422b, 422a, respectively, from the garment tubing 412b.

[0035] In some aspects, the first connector portion 408 may be made from a rigid material and the second connector portion 410 may be made from a flexible material. The rigid material may be made from polyvinyl chloride (PVC), polyurethane, acrylonitrile butadiene styrene (ABS), or the like. The flexible material may be made from liquid silicone. The adhesive layer may be made of Liquid Silicone Rubber (LSR), Polyvinyl Chloride (PVC), Thermoplastic Elastomer (TPE), or the like. By making first connector portion 408 from a rigid material and second connector portion 410 from a flexible material, connecting first connector portion 408 and second connector portion 410 may be easier than if first connector portion 408 and second connector portion 410 were made from the same material due to the flexibility of second connector portion 410. However, in other aspects, first connector portion 408 and second connector portion 410 may be made from the same material.

[0036] 3a, 3b, and 3c, the first connector portion 308 and the second connector portion 310 (similar to the first connector portion 108 and the second connector portion 110 of FIG. 1 and the first connector portion 408 and the second connector portion 410 of FIGS. 4a and 4b) may include contact pads 332, such as grips, non-slip grips, or textured grips, on the outer concentric walls 306a, 306b. For example, the first connector portion 308 may include contact pads 332 on the top and / or bottom of the outer concentric wall 306a. In another example, the second connector portion 310 may include contact pads 332 on the top and / or bottom of the outer concentric wall 306b. Contact pads 332 may assist in connecting first connector portion 308 and second connector portion 310 by providing a non-sliding surface.The material of the contact pads can be similar to that of the connector portions 308, 310, i.e., Acrylonitrile Butadiene Styrene (ABS), Polycarbonate (PC), Polyvinyl Chloride (PVC), Nylon (PA), Polyurethane (PU), ABS-like resin, PC-like resin, Polybutylene Terephthalate (PBT), Polyetheretherketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic), POM (acetal / Delrin), PP (polypropylene), Polyphenylene Ether (PPE), Polyphenylene Sulfide (PPS), Polystyrene (PS), PTFE (Teflon), and High-density polyethylene (HDPE), Liquid Crystal Polymer (LCP). Crystal Polymer (LCP), Low-density Polyethylene (LLDPE), Linear Low-density Polyethylene (LLDPE), Ultra-high molecular weight polyethylene. The polymer may be any one or combination of polymers selected from the group consisting of ultra-high-molecular-weight polyethylene (UHMW), polyethylene terephthalate (PE ...

[0037] 3a and 3b, the outer concentric walls 306a, 306b and the intermediate concentric walls 304a, 304b of the first connector portion 308 and the second connector portion 310 may have a substantially rectangular shape. The corners of the outer concentric walls 306a, 306b and the intermediate concentric walls 304a, 304b may be rounded. As illustrated, the inner concentric walls 314a of the first connector portion 308 and the inner concentric walls 314b of the second connector portion 310 may be circular or elliptical. In other aspects of the present disclosure, the inner concentric walls 314a of the first connector portion 308 and the inner concentric walls 314b of the second connector portion 310 may have a rectangular shape, a substantially rectangular shape, a square shape, a substantially square shape, or an elliptical shape.

[0038] 5a shows a perspective view of another embodiment of a reversible connector 520 according to an aspect of the present disclosure, with first and second connector portions 508, 510 in an engaged position. The first and second connector portions 508, 510 are similar to the first and second connector portions 108, 110 shown in FIG. 1, the first and second connector portions 308, 310 shown in FIGS. 3a-3c, and the first and second connector portions 408, 410 shown in FIGS. 4a-4b. In this embodiment, the first and second connector portions 508, 510 may have an oval or circular outer shape.

[0039] 5b and 5c show perspective views of a first connector portion 508 and a second connector portion 510, each having an oval or circular outer shape. As illustrated, the outer concentric walls 506a, 506b and intermediate concentric walls 504a, 504b of the first connector portion 508 and the second connector portion 510 may have an oval or circular shape. The outer concentric walls 506a, 506b are similar to the outer concentric walls 306a, 306b shown in FIGS. 3b and 3c and the outer concentric walls 406a, 406b shown in FIGS. 4a and 4b.

[0040] In some aspects, the outer concentric wall 506a, the middle concentric wall 504a, and the inner concentric wall 514a of the first connector portion 508 can each include a circumferential recess having a sealing member (e.g., an O-ring) positioned in the circumferential recess (not illustrated) of each of the concentric walls 506a, 504a, 514a. The concentric walls 504a, 504b, 514a, and 514b are similar to the concentric walls 304a, 304b, 314a, and 314b shown in Figures 3b and 3b, and the concentric walls 408, 404b, 414a, and 414b shown in Figures 4a and 4b. For example, the recess in outer concentric wall 506a may receive sealing member 542a, the recess in middle concentric wall 504a may receive sealing member 542b, and the recess in inner concentric wall 514a may receive sealing member 542c. A perspective view of sealing members 642a, 642b, 642c (similar to sealing members 542a, 542b, 542c shown in FIG. 5b) is also illustrated in FIG.

[0041] 7a shows another exemplary perspective cross-sectional view of a reversible connector 720 with first and second portions 708, 710 in an engaged position and a fluid flow connecting channel in a first orientation defining a first configuration indicating the direction of fluid flow from a fluid source of the controller to the compression garment, according to an embodiment of the present disclosure. The reversible connector 720 having the first and second portions 708, 710 is similar to the reversible connector 120, 108, 110 shown in FIG. 1, the reversible connector 320, 308, 310 shown in FIGS. 3a-3c, the reversible connector 420, 408, 410 shown in FIGS. 4a-4b, and the reversible connector 520, 508, 510 shown in FIGS. 5a-5c.

[0042] The sealing members 642a, 642b, and 642c shown in FIG. 6 are the first connector portion 7. 6 may help create a seal for each of the corresponding chambers 702, 704, 706 (shown in FIGS. 7a and 7b) when first connector portion 708 is engaged with second connector portion 710 to form reversible connector 720. The use of sealing members 642a, 642b, and 642c, shown in FIG. 6, may allow first connector portion 708 and second connector portion 710 to more easily connect when engaged. In some aspects, first connector portion 708 may be made from a rigid material, while female connector portion 710 may be made from a flexible material. In other aspects, first connector portion 708 and second connector portion 710 may be made from the same material.

[0043] FIG. 7b shows another exemplary top cross-sectional view of a reversible connector 720 according to an embodiment of the present disclosure, with the first and second portions 708, 710 in an engaged position and the cooperating first and second fluid flow connecting channels in a second orientation defining a second configuration indicating the direction of fluid flow from the controller fluid source to the compression garment.

[0044] 7a and 7b show a reversible connector 720 in a first orientation and in a second orientation where the first portion 708 and the second portion 710 are engaged and the fluid flow is the same as the fluid flow illustrated in FIGS. 4a and 4b.

[0045] Figures 8a and 8b show perspective views of a first connector portion 808 having a sealing member around an outer concentric wall and a second connector portion 810 having a gasket 860. First connector portion 808 and second connector portion 810 are similar to first connector portion 108 and second connector portion 110 shown in Figure 1, first connector portion 308 and second connector portion 310 shown in Figures 3a-3c, first connector portion 408 and second connector portion 410 shown in Figures 4a-4b, and first connector portion 708 and second connector portion 710 shown in Figures 7a-7b.

[0046] As illustrated in FIG. 8a, first connector portion 808 can include an outer concentric wall 806a having a circumferential recess (not illustrated) with a sealing member 842a, such as an O-ring, positioned in the circumferential recess. Sealing member 842a is similar to sealing member 542a shown in FIG. 5b and sealing member 642a shown in FIG. 6. FIG. 8b shows second connector portion 810 having outer concentric wall 806b and gasket 860 having middle concentric wall 844 and inner concentric wall 850. As illustrated, gasket 860 is positioned within outer concentric wall 806b of second connector portion 810. Gasket 860 can be made of a flexible material. The flexible material of gasket 860 may allow for easier insertion of gasket 860 into outer concentric wall 806b compared to insertion of a non-flexible gasket 860 into outer concentric wall 806b. The flexible material of gasket 860 may also allow for easier connection of first connector portion 808 and second connector portion 810. In another aspect, the gasket may be made from a rigid material.

[0047] 8c shows the second connector part 810 without the gasket 860. The base 302b of the second connector part 810 may include three gasket fluid flow passages 866a, 866b, 866c, each aligned with a corresponding fluid flow passage 326a, 326b, 326c (shown in FIG. 3c) in the second connector part 810. Each gasket fluid flow passage 866a, 866b, and 866c may have a corresponding fluid flow passage wall 862a, 862b, and 862c that surrounds the gasket fluid flow passage 866a, 866b, and 866c. For example, fluid flow passage 862a may be aligned with fluid flow passage 866a (shown in FIG. 3c) with fluid flow passage wall 862a fitting inside gateway fluid flow passage 326a, gateway fluid flow passage 866b may be aligned with fluid flow passage 866b (shown in FIG. 3c) with fluid flow passage wall 862b fitting inside gateway fluid flow passage 326b, and gateway fluid flow passage 866c may be aligned with fluid flow passage wall 862c fitting inside gateway fluid flow passage 326c. In the mated state, it may be aligned with fluid flow passage 866c (shown in FIG. 3c).

[0048] FIG. 8d shows gasket 860. Gasket 860 may be made from liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), or similar materials. Intermediate concentric wall 844 and inner concentric wall 850 of gasket 860 may replace intermediate concentric wall 304b and inner concentric wall 314b (shown in FIG. 3c) of the embodiment of the present disclosure described above with respect to second connector portion 310 (which is similar to second connector portion 810). Intermediate concentric wall 844 of gasket 860 may include fluid flow passages 846a, 846b, and 846c, which replace 326a, 326b, and 326c (shown in FIG. 3c) of the embodiment of the present disclosure described above with respect to second connector portion 310. The intermediate concentric wall 844 may include bump-outs 848a, 848b that replace the bump-outs 330a, 330b (shown in FIG. 3c) of the previous embodiment of the present disclosure described above with respect to the second connector portion 310.

[0049] The use of sealing member 842a (shown in FIG. 8a) may help create a seal for chamber 702 (shown in FIGS. 7a and 7b) when first connector portion 808 is slidably engaged with second connector portion 810, as shown in FIGS. 8a and 8b. The use of sealing member 842a and gasket 860 may allow first connector portion 808 and second connector portion 810 to more easily connect when engaged.

[0050] 4a and 4b, in accordance with another aspect of the present invention, only one or two of the tubes 422a, 422b, and 422c of the garment piping 412b may be required for use on a compression garment (not shown), for example, with fewer than three inflatable bladders. In such an embodiment, the garment piping 412b may include only the tubes 422a, 422b, and 422c necessary to operate the compression garment according to this embodiment, e.g., only one tube 422a for a single-bladder compression garment (not shown). For example, if the compression garment includes only one tube 422a, the user may connect the tube 422a to any one of the inlets 416a, 416b, and 416c. During a setup and initialization cycle, the controller may individually deliver a small flow of pressurized fluid to each of the inlets 416a, 416b, and 416c and individually determine whether the inlets 416a, 416b, and 416c are connected to the tube 422a. If the controller determines that any one or more of the inlets 416a, 416b, 416c is not connected to the tubing 422a, the controller then supplies pressurized fluid only to the inlets for which the tubing 422a is present. In this manner, the reversible connector is adaptable for use with any combination of tubing 422a, 422b, 422c connected to the inlets 416a, 416b, 416c.

[0051] 9a-9d show perspective views of an exemplary reversible connector according to embodiments of the present disclosure. Variations can include a first connector portion 908, a second connector portion 910, and / or a third connector portion 912. While the first connector portion 908, the second connector portion 910, and the third connector portion 912 are shown in a particular configuration in FIG. 9a (i.e., first connector portion 908 engages with the second connector portion 910, and tubing 913 connects the second connector portion 910 to the third connector portion 912), the described connector and embodiments are applicable to any configuration. In the example shown in FIG. 9a, the third connector portion 912 can be a controller connector configured to connect to and provide fluid communication with, for example, a controller (e.g., controller 102 of FIG. 1 above and / or controller 902 of FIGS. 9q-9s below). Additionally, first connector portion 908 is connected to an inflatable bladder (e.g., bladders 106a, 106b, and / or 106c) of a compression garment (e.g., compression garment 104 of FIG. 1) via compression garment tubing 942. 9a, third connector portion 912 and second connector portion 910 may be connected via tubing 913. Tubing 913 provides fluid communication between corresponding passages in third connector portion 912 and second connector portion 910. Tubing 913 may have, for example, three separate passages or conduits 922a, 922b, and 922c therein. In one embodiment, tubing 913 may be similar to tubing 212 or 213 described with reference to FIGS. 2a and 2B above or FIGS. 11a and 11b below.

[0052] First connector portion 908 and second connector portion 910 may alternatively be referred to as a male connector and a female connector, respectively, and third connector portion 912 may alternatively be referred to as a male connector. First connector portion 908, second connector portion 910, and / or third connector portion may be similar to controller-side first connector portion 108a and sleeve-side reversible second connector portion 110a shown in FIG. 1, first connector portion 308 and second connector portion 310 shown in FIGS. 3A-3C, first connector portion 408 and second connector portion 410 shown in FIGS. 4A-4B, first connector portion 508 and second connector portion 510 shown in FIGS. 5A-5C, first connector portion 708 and second connector portion 710 in FIGS. 7A-7B, and / or first connector portion 808 and second connector portion 810 in FIGS. 8A-8D. Additionally, the first connector portion 908 may be similar to, for example, the sleeve-side connection portion 110a of FIG. 1. Additionally, the second connector portion 910 may be similar to the first reversible connection portion 108b, and the third connector portion 912 may be similar to the second reversible connection portion 110b. The third connector portion 912 may be connectable to, for example, a controller (e.g., the controller 102 of FIG. 1) and / or configured to connect to a controller-side reversible connector portion (e.g., the controller-side reversible first connection portion 108a of FIG. 1).

[0053] FIG. 9a shows a first connector portion 908 connected to a second connector portion 910. While not limited to the foregoing configuration, the first connector portion 908 may provide fluid communication with a compression garment (e.g., compression garment 104 of FIG. 1 ), for example, via compression garment tubing 942. The third connector portion 912 is shown in a disconnected state and may be configured to connect to a controller (e.g., controller 102 of FIG. 1 and / or controller 902 of FIGS. 9q-9s). Examples of reversible controller connections are described in detail below with respect to FIGS. 9q and 9s. FIG. 9b shows a perspective view of the first connector portion 908, FIG. 9c shows a perspective view of the second connector portion 510, and FIG. 9d shows an example of the third connector portion 912. Further details of the connector portions are described in detail below with respect to FIGS. 9e-9r and 12a-15b.

[0054] As illustrated, the first connector portion 908 can have an outer housing 915a and a sealing member 909a having an outer wall 906a, an intermediate concentric wall 904a, and an inner concentric wall 914a. FIG. 9c is a view of a second connector portion 910 separated from the first connector portion 908. Note that the orientation of the second connector portion 910 in FIG. 9c is for visual clarity and does not necessarily indicate the assembly orientation. As shown in FIG. 9c, the second connector portion 910 can have an outer housing 915b, an outer seal engagement wall 906b, an intermediate concentric wall 904b, and an inner concentric wall 914b. When the first connector portion 908 and the second connector portion 910 are connected (e.g., as shown in FIG. 9a), the outer wall 906a, the intermediate concentric wall 904a, and the inner concentric wall 914a of the sealing member 909a may sealingly engage with the outer seal engagement wall 906b, the intermediate concentric wall 904b, and the inner concentric wall 914b, respectively, to create a chamber that forms a fluid passage within the interface of the first connector portion 908 and the second connector portion 910. The third connector portion 912 includes an outer housing 915c and a sealing member 909c having an outer wall 906c, an intermediate concentric wall 904c, and the inner concentric wall 914c. In some aspects, the sealing member 909c of the third connector portion 912 may be identical to the sealing member 909a of the first connector portion 908, which , may reduce production costs and / or provide ease of replacement or reprocessing of the connector and / or associated devices (e.g., compression garments, adapters, extension devices, and / or controllers).

[0055] As shown in FIG. 9e, the first connector portion 908 may include a first connector outer housing 915a. The outer housing 915a may be a separate component from the sealing member 909a, as shown in FIGS. 9f and 9g. Referring to FIG. 9g, the sealing member 909a may be a single, integral structure and may include an outer concentric wall 906a, an intermediate concentric wall 904a, and an inner concentric wall 914a. The sealing member 909a may further include a first opening 991a corresponding to the first fluid passage 1 of the first connecting portion, a second opening 992a corresponding to the second fluid passage 2 of the first connecting portion 912, and a third opening 993a corresponding to the third fluid passage 3 of the first connecting portion 912. The inner concentric wall 914a may be positioned within the intermediate concentric wall 904a, and the intermediate concentric wall 904c may be positioned within the outer concentric wall 906a of the first connector portion 908. The sealing member 909a may be formed of a flexible or semi-flexible material. The sealing member 909a may further include a single or multiple support structures (e.g., 929a in FIG. 9g). The support structures may comprise sections of material having a larger cross-sectional area than the remainder of the sealing member 909a and may prevent any one or combination of the first outer concentric wall 906a, the middle concentric wall 904a, and / or the inner concentric wall 914b from buckling or otherwise breaking the seal or causing leakage at the interface between the first connector portion 908 and the second connector portion 910. The first connector outer housing 915a may be formed of, for example, a rigid or semi-rigid material. While only a single support structure is referenced in FIG. 9I to avoid obstructing the illustration, any number of support structures may be used without departing from the scope of the present disclosure. For example, as shown in FIG. 91, the sealing portion 929b may have 14 support structures. In one embodiment, the sealing member may be molded, additively manufactured, extruded, and / or machined from any one or combination of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomers (TPE), thermoplastic vulcanizates (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam, and / or open-cell PE foam, or the like.In a preferred embodiment, sealing portion 929b is injection molded low durometer polyvinyl chloride (PVC). For example, the outer housing 915a may be molded, additively manufactured, extruded, and / or machined from any one or combination of acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), nylon (PA), polyurethane (PU), ABS-like resins, PC-like resins, polybutylene terephthalate (PBT), polyether ether ketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic), POM (acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon), and high density polyethylene (HDPE), liquid crystal polymer (LCP), low density polyethylene (LLDPE), linear low density polyethylene (LLDPE), ultra-high molecular weight polyethylene (UHMW), or the like. In a preferred embodiment, the outer housing 915a is injection molded acrylonitrile butadiene styrene (ABS).

[0056] 9h and 9i, the second connector portion 910 can include a second connector outer housing 915b, an outer concentric wall 906b, an intermediate concentric wall 904b, and an inner concentric wall 914b. The inner concentric wall 914b can be positioned within the intermediate concentric wall 904b, which can be positioned within the outer concentric wall 906b of the second connector portion 910. In one exemplary implementation, the second connector outer housing 915b, the outer concentric wall 906b, the intermediate concentric wall 904b, and the inner concentric wall 914b can be formed as a unitary component. In one example, the second connector outer housing 915b, the outer concentric wall 906b, the intermediate concentric wall 904b, and the inner concentric wall 914b can be formed of a rigid or semi-rigid material, for example. For example, the second connector outer housing 915b, the outer concentric wall 906b, the middle concentric wall 904b, and the inner concentric wall 914b may be made of acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), nylon (PA), polyurethane (PU), ABS-like resin, PC-like resin, polybutylene terephthalate (PBT), polyether ether ketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic), POM (acetate), The second connector outer housing 915b may be molded, additively manufactured, extruded, and / or machined from any one or combination of: (polyethylene / delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon), and high density polyethylene (HDPE), liquid crystal polymer (LCP), low density polyethylene (LLDPE), linear low density polyethylene (LLDPE), ultra-high molecular weight polyethylene (UHMW), or the like. In a preferred embodiment, the second connector outer housing 915b, outer concentric wall 906b, middle concentric wall 904b, and inner concentric wall 914b are injection molded acrylonitrile butadiene styrene (ABS).

[0057] 9j, the third connector portion 912 may include a third connector outer housing 915c. The third connector portion 912 may alternatively be referred to as a male connector throughout this disclosure. The outer housing 915c may be a separate component from the sealing member 909c, as shown in FIGS. 9k and 9I. Referring to FIG. 9I, the sealing member 909c may be a single, integral structure and may include an outer concentric wall 906c, an intermediate concentric wall 904c, and an inner concentric wall 914c. The inner concentric wall 914c may be positioned within the intermediate concentric wall 904c, which may be positioned within the outer concentric wall 906c in the first connector portion 908. The sealing member 909c may further include a first opening 991c corresponding to the first fluid passage 1 of the third connecting portion, a second opening 992c corresponding to the second fluid passage 2 of the third connecting portion 912, and a third opening 993c corresponding to the third fluid passage 3 of the third connecting portion 912. The sealing member 909c may be formed of a flexible or semi-flexible material. The sealing member 909a may further include a single or multiple support structures (e.g., 929c in FIG. 9I). The support structure may comprise a section of material having a larger cross-sectional area than the remainder of the sealing member 909a and may prevent any one or combination of the first outer concentric wall 906c, the middle concentric wall 904c, and / or the inner concentric wall 914c from buckling, "bursting," or otherwise breaking the seal or causing a leak at the interface between the third connector portion and a connector connected thereto (e.g., the controller side or fourth connectors 941a and / or 941b in Figures 9q-9s described below). In one aspect, the third connector may be configured to connect to a connector having similar features or that is identical to the second connector portion 910. In one embodiment, the sealing member 909c may be molded, additively manufactured, extruded, and / or machined from any one or combination of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic vulcanizate (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam, and / or open-cell PE foam, or the like.In a preferred embodiment, sealing portion 909c is injection molded low durometer polyvinyl chloride (PVC). For example, the outer housing 915c may be molded, additively manufactured, or extruded from any one or combination of acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), nylon (PA), polyurethane (PU), ABS-like resins, PC-like resins, polybutylene terephthalate (PBT), polyetheretherketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic), POM (acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon), and high density polyethylene (HDPE), liquid crystal polymer (LCP), low density polyethylene (LLDPE), linear low density polyethylene (LLDPE), ultra-high molecular weight polyethylene (UHMW), or the like. , and / or machined. In a preferred embodiment, the outer housing 915c is injection molded acrylonitrile butadiene styrene (ABS). As described below, the third connector may include one or more tie-down portions 918 configured for passage of a tie-down portion or label connection portion. Further exemplary aspects of tie-down portion functionality are described below with respect to FIG. 9r.

[0058] 9m and 9n, examples of fluid paths are described below. The first connector portion may include a tubing connection portion 985a, and the second connector portion may include a tubing connection portion 985b, which may be removably or permanently connectable to, for example, tubing 112b, 112c, and / or 112a of FIG. 1, tubing 212 or 213 of FIGS. 2a and 2b, tubing 422a-422c of FIGS. 4a-4b, tubing 722a-722c of FIGS. 7a-7b, or tubing 913 and / or 942 of FIGS. 9a and 9r.

[0059] 9m and 9n are first connector portion 908 and second connector portion 910, although the same aspects may be applicable to third connector portion 912 and / or fourth connector or controller-side connector (e.g., controller-side connectors 1914a and / or 1914b in FIGS. 19a-19c). In some aspects, outer concentric wall 906a, middle concentric wall 904a, and inner concentric wall 914a of first connector portion 908 may be adapted (i.e., sized) to engage with outer concentric wall 906b, middle concentric wall 904b, and inner concentric wall 914b of second connector portion 910 shown in FIG. 9e to form reversible connector 920 in an engaged configuration, as illustrated in FIGS. 9a, 9m, and 9n. 9m and 9n, the outer concentric wall 906a of the first connector portion 908 can engage with the outer surface of the outer concentric wall 906b of the second connector portion 910. The middle concentric wall 904a of the first connector portion 908 can engage with the outer surface of the middle concentric wall 904b of the second connector portion 910. Furthermore, as shown in FIG. 9m, when the first connector portion 908 is engaged with the second connector portion 910 to form the reversible connector 920 in the first engaged configuration, the inner concentric wall 914a of the first connector portion 908 can engage with the outer surface of the inner concentric wall 914b of the second connector portion 910.

[0060] 9n and described further below, the first connector portion 908 and the second connector portion 910 can be connected in a second mating configuration (e.g., a “reversed” configuration) without changing the order of the paths of fluid communication. For example, the first connector portion 908 can have a tubing connection portion 985a with three separate fluid paths (e.g., paths 1, 2, and 3). Similarly, the second connector portion 910 can have a tubing connection portion 985b with three separate fluid paths (e.g., paths 1, 2, and 3). As shown in FIG. 9m, in the first mating configuration, the respective orders of fluid paths 1, 2, and 3 of the first connector portion 908 and the second connector portion 910 are matched and flow through the first fluid flow channel. As shown by arrow 980, with the connection “reversed” (e.g., one of the first connector portion 908 or the second connector portion 910 flipped 180 degrees), fluid paths 1, 2, and 3 of the first connector portion 908 and the second connector portion 910 are still aligned while flowing through the second fluid flow channel due to the concentric wall arrangement described above. As described in more detail below with respect to FIGS. 19a-19c below, features such as a funnel portion 917 improve consistency of fluid flow and pressure regardless of the orientation in which the first connector portion 908 and the second connector portion 910 are connected. As shown in FIGS. 9m and 9n, the first connector portion 908 and the second connector portion 910 can have respective first and second connector engaging portions 916a and 916b. The first connector engaging portion 916a can be configured to mate within the second connector engaging portion 916b. The engagement between the first connector engaging portion 916a and the second connector engaging portion 916b may, for example, provide a guide for connecting the first connector portion 908 to the second connector portion 910. In one embodiment, any one or a combination of the connector portions may have a locking mechanism to ensure a secure connection and sealing engagement between two or more connectors. One example of such a mechanism is shown in FIGS. 9a-9d. In the embodiment shown, the locking mechanism of the first connector portion 908 includes at least one pressing portion 944a and a locking portion 945a. Either or both of the pressing portion 944a and / or locking portion 945a may be biased or otherwise tensioned such that pressing the pressing portion 944a causes the locking portion 945a to engage or disengage with the locking portion 945b of the second connector portion 910. In one embodiment, the pressing portion 944a and / or locking portion 945a may be connected to the first connecting portion via a plastic biasing member or other element configured to plastically deform or deflect when a user presses the locking portion. The second connector locking mechanism may include, for example, one or more openings 943 configured to lockingly receive locking portion 945 a of first connector portion 908. Such locking mechanism may, for example, lock first connector portion 908 in place once first connector portion 908 and second connector portion 910 are connected and sealingly engaged. First connector portion 908 and second connector portion 910 may lock when a user pushes first connector portion 908 into second connector portion 910 until locking portion 945 a is lockingly received within one or more openings 943. When a user desires to remove first connector portion 908 from second connector portion 910, applying a pressing force to pressing portion 944a causes locking portion 945a to move downward and release the locking engagement with one or more openings 943, thereby allowing the user to separate first connector portion 908 from second connector portion 910. Third connector portion 912 may additionally include a similar mechanism including pressing portion 944c and / or locking portion 945c.Although hidden in FIG. 9a, any one or combination of first connector pressure portion 944a, first connector locking portion 945a, and / or second connector locking portion 945b, connector locking portion 945a, and / or locks may be included on a single side or both sides of each of the aforementioned first connector portion 908 and / or second connector portion 910. Any one of the locking mechanisms described above may include a visual, tactile, and / or audible indicator to indicate to a user that the connectors are properly connected. One example of a visual indicator is further described with respect to FIGS. 12a and 12b below.

[0061] 9o and 9p, the aforementioned sealing engagement between the first connector portion 908, the second connector portion 910, and / or the third connector portion 912 can be a friction-fit or interference-fit type interface. For example, the outer concentric wall 906a of the first connector portion 908 can slidingly or frictionally engage the outer surface of the outer concentric wall 906b of the second connector portion 910. For example, the outer concentric wall 906a of the first connector portion 908 can be formed of a material that is more flexible than the outer concentric wall of the second connector portion 910. In the aforementioned embodiment, the outer concentric wall 906a of the first connector portion 908 can have one or more inner dimensions that are substantially the same as or slightly smaller than the outer concentric wall 906b of the second connector portion 910. Thus, when the two connectors are connected by a user, the outer concentric wall 906a of the first connector portion 908 frictionally engages the outer concentric wall 906b of the second connector portion 910, forming a seal therebetween that allows no or only minimal fluid loss at the interface. Similarly, the middle concentric wall 904a of the first connector portion 908 may slidingly or frictionally engage the outer surface of the middle concentric wall 904b of the second connector portion 910. The inner concentric wall 914a of the first connector portion 908 may also slidingly or frictionally engage the outer surface of the inner concentric wall 914b of the second connector portion 910 when the first connector portion 908 is engaged with the second connector portion 910 to form the reversible connector 920 in a first engaged configuration. Between the outer concentric wall 906a of the first connector portion 908 and the outer concentric wall 906b of the second connector portion 910, between the middle concentric wall 904a of the first connector portion and the middle concentric wall 904b of the second connector portion 910, and between the inner concentric wall 914a of the first connector portion 908 and the inner concentric wall 914b of the second connector portion 910. A close-up view of the friction or interference fit between connectors 908 and 910 is shown in Figure 9p. The connectors referenced above are first connector portion 908 and second connector portion 910, but the same aspects may be applicable to third connector portion 912 and / or fourth connector or controller-side connectors (e.g., controller-side connectors 941a and / or 941b in Figures 9q-9s).

[0062] Figure 9q shows a partial view of an embodiment of a controller 902 having two reversible controller connector portions 941a and 941b. Controller 902 may be similar to, for example, controller 102 of Figure 1. Additionally, either or both of the reversible controller connector portions may be similar to any one or combination of first connector portion 108a or 108b or second connector portion 110a or 110b of Figure 1, first connector portion 308 or second connector portion 310 of Figures 3a-3c, first connector portion 408 or second connector portion 310 of Figures 4a-4b, first connector portion 508 or second connector portion 510 of Figures 5a-6, first connector portion 708 or second connector portion 710 of Figures 7a-7b, and / or first connector portion 808 or second connector portion 810 of Figures 8a-8d.

[0063] In the embodiment shown in FIG. 9r, the reversible connector includes a third connector portion 912 and a second connector portion 910, with tubing 913 connecting the third connector portion 912 and the second connector portion 910. One or both of the controller-side reversible connection portions 941a and / or 941b may be configured to sealingly engage with the reversible connector (e.g., third connector portion 912). Either or both of the controller-side reversible connection portions 941a and / or 941b may have a locking mechanism with one or more locking portions 942a and / or 942b. The locking portions 942a and / or 942b may be configured to lockingly engage with a locking portion 945c of the third connector portion 912 when the third connector is pushed into the controller-side connection portion 941. In one aspect, pressing the pressing portion 944c (FIG. 9a) of the third connector portion disengages the locking portion 945c from one or more locking portions 942a and / or 942b of the controller side connecting portion 944.

[0064] In one aspect, the controller body or controller body connection portion may include a monitor tie-down portion corresponding to each monitor connection portion 941a and / or 941b. The monitor tie-down portion 919 may be configured to allow a portion of a tie or label to pass through. In one example, both the monitor tie-down portion 919 and one or more tie-down portions 918 of the third connector portion 912 may allow a tie or label to pass through. Threading a tie through both the third connector tie-down portion 918 and the monitor tie-down portion 919 may prevent accidental removal of the connector from the monitor. In another example, threading a label through either or both the third connector tie-down portion 918 and the monitor tie-down portion 919 may provide information about the patient and / or the equipment to a user or technician, for example, to name a few non-limiting examples.

[0065] 9s shows a cross-sectional view of engagement between one of two controller-side reversible connection portions 941a and / or 941b. One or both of the two controller-side reversible connection portions 941a and / or 941b may alternatively be referred to as a female connection throughout this disclosure. As noted above, either or both of the controller-side reversible connector portions may be mated with first connector portion 108a or 108b or second connector portion 110a or 110b of FIG. 1, first connector portion 308 or second connector portion 310 of FIGS. 3a-3c, first connector portion 408 or second connector portion 310 of FIGS. 4a-4b, first connector portion 508 or second connector portion 510 of FIGS. 5a-6, first connector portion 708 or second connector portion 710 of FIGS. 7a-7b, and / or second connector portion 808 or second connector portion 810 of FIGS. 8a-8b. The third connector portion 908 may be similar to any one of the first connector portion 808 or the second connector portion 810 of FIGS. 8a-8d, or a combination thereof. In one embodiment, one or both of the two controller-side reversible connection portions may be connected to the controller via a length of tubing. As shown in FIG. 9s, the aforementioned sealing engagement between the third connector portion 912 and the controller-side reversible connection portion 941 may be a friction-fit or interference-fit type interface. For example, the outer concentric wall 906c of the third connector portion 908 may slidingly or frictionally engage with the outer surface of the outer concentric wall 906d of the monitor-side reversible connector portion 941. The outer concentric wall 906c of the third connector portion 912 may be formed of a material that is more flexible than the outer concentric wall of the controller-side reversible connector portion 941. The foregoing embodiments may be reversed (e.g., the outer concentric wall 906d of the controller-side connector portion 941 may be formed of a material that is more flexible than the outer concentric wall 906c of the third connector portion 912) without departing from the scope of the present disclosure. In another embodiment, the outer concentric wall 906c of the third connector portion 912 may be formed of a material having the same or similar flexibility as the outer concentric wall 906d of the controller-side reversible connector portion 941. In the foregoing example, the outer concentric wall 906c of the third connector portion 912 may have one or more interior dimensions that are substantially the same as or slightly smaller than the outer concentric wall 906d of the controller-side reversible connection portion 941. Thus, when the two connectors are connected by a user, the outer concentric wall 906c of the third connector portion 912 frictionally engages the outer concentric wall 906d of the monitor-side reversible connection portion 941, forming a seal therebetween that allows no or only minimal fluid loss at the interface. Similarly, the middle concentric wall 904c of the third connector portion 912 may slidingly or frictionally engage with the outer surface of the middle concentric wall 904d of the monitor-side reversible connection portion 941. The inner concentric wall 914c of the third connector portion 912 may also slidingly or frictionally engage with the outer surface of the inner concentric wall 914d of the monitor-side reversible connection portion 941 when the third connector portion 912 is engaged with the monitor-side reversible connection portion 914 in the first engagement configuration.

[0066] 10a and 10b, one exemplary rear or posterior side of a sealing member 1009 is shown. The sealing member 1009 may be similar to the sealing member 909a shown in FIGS. 9b, 9e, 9g, 9m-9p, and / or the sealing member 909c shown in FIGS. 9a, 9d, and 9j-9l. For example, in addition to the previously described features of sealing members 909a and / or 909c, the sealing member 1009 may include a rear engagement portion 1054 with a rear engagement portion outer seal 1056, a first alignment horn 1055a, and a second alignment horn 1055b. The rear engagement portion 1054 on the rear or posterior side of the sealing member 1009 may be configured to interface with a connector portion interface 1064 of the connector portion 1008. The connector portion 1064 may be similar to the controller-side first connector portion 108a and the sleeve-side reversible second connector portion 110a shown in FIG. 1, the first connector portion 308 and the second connector portion 310 shown in FIGS. 3A-3C, the first connector portion 408 and the second connector portion 410 shown in FIGS. 4A-4B, the first connector portion 508 and the second connector portion 510 shown in FIGS. 5A-5C, the first connector portion 708 and the second connector portion 710 in FIGS. 7A-7B, and / or the first connector portion 808 and the second connector portion 810 in FIGS. 8A-8D. Additionally, the connector portion 1008 may be similar to, for example, the sleeve-side connection portion 110a in FIG. 1. The connector portion interface 1064 may include an outer seal receiving portion 1066, a first horn receiving portion 1065a, and a second horn receiving portion 1065b. Thereby, connector portion interface 1064 of connector portion 1008 can be configured to engage with rear engagement portion 1054 of sealing member 1009. For example, outer seal 1056 of rear engagement portion 1054 can be a protruding section of sealing member 1009 configured to be received by outer seal receiving portion 1066 of connector portion interface 1064. Similarly, second horn receiving portion or first horn receiving portion 1065a can be configured to engage or otherwise receive first alignment horn 1055a, and second horn receiving portion 1065b can be configured to engage or otherwise receive second alignment horn 1055b. The foregoing structure ensures that the sealing member 1009 is installed in the proper orientation during manufacturing and / or refurbishment of the reversible connector.

[0067] Figure 11a is a top cross-sectional view of an embodiment of a reversible connector showing the interaction between tubing 1113 and first and second connector portions 1110, 1112. First and second connector portions 1110, 1112 may be similar to controller-side first connector portion 108a and sleeve-side reversible second connector portion 110a shown in Figure 1, first and second connector portions 308, 310 shown in Figures 3A-3C, first and second connector portions 408, 410 shown in Figures 4A-4B, first and second connector portions 508, 510 shown in Figures 5A-5C, first and second connector portions 708, 710 in Figures 7A-7B, and / or first and second connector portions 808, 810 in Figures 8A-8D. Additionally, the first connector portion 1108 may be similar to, for example, the sleeve-side connection portion 110a of FIG. 1. Additionally, the second connector portion 1110 may be similar to the first reversible connection portion 108b, and the third connector portion 1112 may be similar to the second reversible connection portion 110b. The first reversible connection portion 1112 may also be similar to the third connector portion 912 of FIGS. 9a, 9d, 9j, 9k, and 91 and may be connectable to a controller (e.g., the controller 102 of FIG. 1 and / or the controller 902 of FIGS. 9q-9s) and / or configured to connect to a controller-side reversible connector portion (e.g., the controller-side reversible first connection portion 108a of FIG. 1 and / or the controller-side reversible connection portions 941a and / or 941b of FIGS. 9q-9s).

[0068] FIG. 11a illustrates a cross section of tubing 1113 of FIG. 11a that may be utilized between a fluid source controlled by a controller and a compression garment, according to embodiments of the present disclosure. The tubing profile of tubing 1113 may be implemented to create a fluid path between each of the connectors and / or sleeves (e.g., sleeve 100 of FIG. 1) and / or controllers (e.g., controller 102 of FIG. 1 and / or controller 902 of FIGS. 9q-9s). For example, tubing 1113 may be used as controller tubing 112a and compression garment tubing 112b shown in FIG. 1. Tubing 1113 may also be similar to tubing 913 of FIGS. 9a and 9r. The tubing 1113 may include three separate tube or tubing passages or conduits 1123a, 1123b, and 1123c that correspond to and create a fluid path between the controller (e.g., controller 102 of FIG. 1 and / or controller 902 of FIGS. 9q-9s) and the three bladders 106a, 106b, and 106c of the compression garment 104 (FIG. 1). By way of example, although three tube or tubing passages or conduits 1123a, 1123b, and 1123c are shown and three bladders are provided, embodiments of the present disclosure may include more or fewer passages corresponding to the number of inflatable bladders. For example, the tubing may include two passages providing fluid communication to two bladders, or may include four or more passages providing fluid communication to a corresponding number of bladders. For example, the tubing may include four to six passages in one exemplary implementation. In some aspects, the tubing 212 may be similar to the tubing described above with respect to FIG. 2a, but may additionally include an additional alignment section 1121. The alignment section 1121 may include an additional passage or alignment mechanism, for example, comprising a first alignment portion 1124 and a second alignment portion 1125. One function of the alignment portion 1121 may be to ensure that the tubing 1113 is installed in the correct orientation (e.g., not "inverted") relative to either of the connectors 1110 and 1112.In one exemplary implementation of alignment section 1121, first connector 1110 and second connector 1112 may have respective first connector alignment section 1114 and second connector alignment section 1115 configured to receive alignment portion 1121 of tubing 1113. In addition to the aforementioned advantages, the aforementioned tubing geometry may also enhance the symmetry of the tubing and / or connectors connected thereto by providing a symmetrical appearance at the interface between tubing 1113 and first connector portion 1110 and / or second connector portion 1112. This can improve the aesthetics of the device.

[0069] 12a and 12b illustrate an example of a locking mechanism with a visual indicator for confirming proper connection of two or more of the reversible connector portions. Shown are a first connector portion 1208 and a second connector portion 1210. The first connector portion 1208 and the second connector portion 1210 may be similar to the controller-side first connector portion 108a and the sleeve-side reversible second connector portion 110a shown in FIG. 1, the first connector portion 308 and the second connector portion 310 shown in FIGS. 3A-3C, the first connector portion 408 and the second connector portion 410 shown in FIGS. 4A-4B, the first connector portion 508 and the second connector portion 510 shown in FIGS. 5A-5C, the first connector portion 708 and the second connector portion 710 shown in FIGS. 7A-7B, and / or the first connector portion 808 and the second connector portion 810 shown in FIGS. 8A-8D. Additionally, first connector portion 1208 may be similar to, for example, sleeve-side connection portion 110a of FIG. 1. Additionally, second connector portion 1210 may be similar to first reversible connection portion 108b, and third connector portion 912 may be similar to second reversible connection portion 110b. First reversible connection portion 1210 may also be similar to third connector portion 912 of FIGS. 9a, 9d, 9j, 9k, and 91 and may be connectable to a controller (e.g., controller 102 of FIG. 1 and / or controller 902 of FIGS. 9q-9s) and / or configured to connect to a controller-side reversible connector portion (e.g., controller-side reversible first connection portion 108a of FIG. 1 and / or controller-side reversible connection portions 941a and / or 941b of FIGS. 9q-9s). First connector portion 1208 and / or second connector portion 1210 may also be similar to connector portion 1008 of FIG. 10b and connector portions 1112 and / or 1110 of FIG. 11a.

[0070] The locking mechanism 1241 of the first connector 1208 may include at least one pressing portion 1244 and a locking portion 1245 connected via a resilient or semi-resilient connecting portion 1247. Either or both of the pressing portion 1244 and / or the locking portion 1245 may be biased or otherwise tensioned such that pressing the pressing portion 1244 moves the locking portion 1245 into or out of engagement with the locking portion of the second connector 1210. In one embodiment, the pressing portion 1244 and / or the locking portion 1245 may be connected to the first connecting portion 1208 via a plastic biasing member or other element configured to plastically deform or deflect when a user presses the pressing portion 1244. The second connector locking mechanism may include, for example, one or more openings 1245 configured to lockingly receive the locking portion 1245 of the first connector portion 1208. The aforementioned locking mechanism may, for example, lock first connector portion 1208 in place once first connector portion 1208 and second connector portion 1210 are connected and sealingly engaged. First connector portion 1208 and second connector portion 1210 may lock when a user presses first connector portion 1208 into second connector portion 1210 until locking portion 1245 is lockingly received within one or more openings 1243. When a user wishes to remove first connector portion 1208 from second connector portion 1210, applying a pressing force to pressing portion 1244 moves locking portion 1245 downward, releasing the locking engagement with one or more openings 1243, thereby allowing the user to separate first connector portion 1208 from second connector portion 1210. Any one of the locking mechanisms described above may include a visual, tactile, and / or audible indicator to indicate to a user that the connectors are properly connected. For example, as shown in FIG. 12b, locking portion 1245 of first connector portion 1208 may include a visual indicator, such as a colored, brightly colored, or contrastingly colored mechanism, to provide visual confirmation that locking portion 1245 of the first connector is fully engaged and lockingly received within opening 1243 of second connector portion 1210.This provides the aforementioned visual indicator that the first connector 1208 is properly connected to the second connector 1210, and This may provide confirmation to the user that a fluid seal has been established between the two connectors. Additionally, by forcing the first connector portion 1208 into the second connector, the locking portion 1245 may be forced downward, thereby tensioning the elastic or semi-elastic connecting portion 1247 until the locking portion 1245 is aligned with the opening 1243. Once the locking portion 1245 is aligned with the opening 1243, the locking portion 1245 may spring up to a relaxed state, thereby providing a "snap-on" or similar tactile or audible indicator that the first connector 1208 is properly connected to the second connector 1210 and a fluid seal has been established between the two connectors. While a locking mechanism is preferred, those skilled in the art will understand that aspects of the present disclosure still provide benefits to connectors that include a single locking mechanism or no locking mechanism at all.

[0071] 13a and 13b, any one of the aforementioned connectors may include a first or top locking feature 1345, a second or bottom locking feature 1345b, or both a top locking feature 1345a and a bottom locking feature 1345b. A first connector portion 1308 and a third connector portion 1312 are shown in FIGS. 13a and 13b as examples. The first connector portion 1308 and the third connector portion 1312 may be similar to the controller-side first connector portion 108a and the sleeve-side reversible second connector portion 110a shown in Figure 1, the first connector portion 308 and the second connector portion 310 shown in Figures 3A-3C, the first connector portion 408 and the second connector portion 410 shown in Figures 4A-4B, the first connector portion 508 and the second connector portion 510 shown in Figures 5A-5C, the first connector portion 708 and the second connector portion 710 in Figures 7A-7B, and / or the first connector portion 808 and the second connector portion 810 in Figures 8A-8D. Additionally, the first connector portion 1308 may be similar to, for example, the sleeve-side connection portion 110a in Figure 1. Additionally, the third connector portion 1312 may be similar to the first reversible connection portion 108b, and the third connector portion 1312 may be similar to the second reversible connection portion 110b. The first reversible connection portion 1308 may also be similar to the third connector portion 912 of Figures 9a, 9d, 9j, 9k, and 91 and may be connectable to a controller (e.g., the controller 102 of Figure 1 and / or the controller 902 of Figures 9q-9s) and / or configured to connect to a controller-side reversible connector portion (e.g., the controller-side reversible first connection portion 108a of Figure 1 and / or the controller-side reversible connection portions 941a and / or 941b of Figures 9q-9s). First connector portion 1308 or third connector portion 1312 may also be similar to connector portion 1008 of FIG. 10b, 1112 and / or 1110 of FIG. 11a, and / or 1208 or 1210 of FIGS. 12A and 12B.

[0072] In one example, if a connection portion, such as third connector portion 1312, is intended to be connected to a surface-mounted or rigid connector (e.g., reversible controller-side connection portions 941a and / or 941b in FIGS. 9q-9s), third connector portion 1312 may include both a top first feature 1345a and a bottom first feature 1345b so that a user can easily place the third connector portion in either orientation. In some examples, such as first connection portion 1308 shown in FIG. 13a, the connection portion may be intended to be connected to a non-rigid or surface-mounted connector (e.g., reversible sleeve-side connector portion 110a in FIG. 1) that will be connected to additional tubing. In such cases, it may only be necessary to include a first, or top, locking feature 1345 on the connection portion because the two connection portions to be connected can be easily flipped or otherwise aligned before connection.

[0073] 14a and 14b show an example of a strain relief mechanism 1446 that can be used with any of the connection portions described throughout this disclosure. As one example, the strain relief mechanism 1446 is shown with a first connector portion 1408 and a third connector portion 1412. The first connector portion 1408 and the third connector portion 1412 are shown in FIG. 1, the first connector portion 308 and the second connector portion 310 shown in FIGS. 3A-3C, the first connector portion 408 and the second connector portion 410 shown in FIGS. 4A-4B, the first connector portion 508 and the second connector portion 510 shown in FIGS. 5A-5C, the first connector portion 708 and the second connector portion 710 shown in FIGS. 7A-7B, and / or the first connector portion 808 and the second connector portion 810 shown in FIGS. 8A-8D. Additionally, the first connector portion 1408 may be similar to, for example, the sleeve-side connection portion 110a of FIG. 1. Additionally, the third connector portion 1412 may be similar to the first reversible connection portion 108b, and the third connector portion 912 may be similar to the second reversible connection portion 110b. The first reversible connection portion 1410 may also be similar to the third connector portion 912 of Figures 9a, 9d, 9j, 9k, and 91 and may be connectable to a controller (e.g., the controller 102 of Figure 1 and / or the controller 902 of Figures 9q-9s) and / or configured to connect to a controller-side reversible connector portion (e.g., the controller-side reversible first connection portion 108a of Figure 1 and / or the controller-side reversible connection portions 941a and / or 941b of Figures 9q-9s). The first connector portion 1408 and / or the third connector portion 1412 may also be similar to the connector portion 1008 of FIG. 10b, 1112 and / or 1110 of FIG. 11a, 1208 or 1210 of FIGS. 12a and 12b, and 1308 and 1312 of FIGS. 13a and 13b.

[0074] The strain relief portion 1446 may include, for example, an annular radius section configured to control movement and prevent kinking or other potentially damaging bending of the tubing 1413. In one embodiment, the strain relief portion 1446 is made of acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), nylon (PA), polyurethane (PU), ABS-like resins, PC-like resins, polybutylene terephthalate (PBT), polyetheretherketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic), POM (acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon), and high-density polyethylene (HPE). , HDPE), Liquid Crystal Polymer (LCP), Low-density Polyethylene (LLDPE), Linear Low-density Polyethylene (LLDPE), Ultra-high-molecular-weight Polyethylene (UHMW), or the like, or any combination thereof. The outer housing 915a may be molded, additively manufactured, and / or machined from a combination of materials. In a preferred embodiment, the outer housing 915a is injection molded acrylonitrile butadiene styrene (ABS). In some embodiments, the strain relief portion 1446 may be formed of a low durometer material. For example, the strain relief portion 1446 may be any one or combination of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic vulcanizate (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam, and / or open-cell PE foam, or the like.

[0075] The strain relief portion 1446 allows flexibility between the tubing 1413 and the connector portion 1412 while preventing kinking of the tubing, which could block fluid flow and / or damage the tubing 1413.

[0076] 15a, 15b, and 15c show exemplary connector portions usable with embodiments of the present disclosure. Figures 15a, 15b, and 15c show a first connector portion 1508 and a second connector portion 1510, which may alternatively be referred to as a male connector and a female connector, respectively. The first connector portion 1508 and the second connector portion 1510 are similar to the first connector portion 108a and sleeve on the controller side shown in FIG. 1. 1. In addition, first connector portion 1408 may be similar to or include features of sleeve-side connection portion 110a, first connector portion 308 and second connector portion 310 shown in Figures 3A-3C, first connector portion 408 and second connector portion 410 shown in Figures 4A-4B, first connector portion 508 and second connector portion 510 shown in Figures 5A-5C, first connector portion 708 and second connector portion 710 in Figures 7A-7B, and / or first connector portion 808 and second connector portion 810 in Figures 8A-8D. In addition, first connector portion 1408 may be similar to or include features of sleeve-side connection portion 110a in Figure 1, for example. Additionally, second connector portion 1510 may be similar to or include features of first reversible connection portion 108b, and third connector portion 912 may be similar to or include features of second reversible connector portion 110b. First reversible connection portion 1508 may also be similar to or include features of third connector portion 912 of Figures 9a, 9d, 9j, 9k, and 91 and may be connectable to a controller (e.g., controller 102 of Figure 1 and / or controller 902 of Figures 9q-9s) and / or configured to connect to a controller-side reversible connector portion (e.g., controller-side reversible first connection portion 108a of Figure 1 and / or controller-side reversible connection portions 941a and / or 941b of Figures 9q-9s). The first connector portion 1508 and / or the second connector portion 1510 may also be similar to or include features of connector portion 1008 of FIG. 10b, 1112 and / or 1110 of FIG. 11a, 1208 or 1210 of FIGS. 12a and 12b, 1308 and 1312 of FIGS. 13a and 13b, and 1408 and 1412 of FIGS. 14a and 14b.

[0077] As shown in FIG. 15a, the first connector portion 1508 can include a first connector outer housing 1515a. The outer housing 1515a can be a separate component from the sealing member 1509 (e.g., similar to the embodiment described in FIGS. 9f and 9g). Referring to FIG. 15c, the sealing member 1509 can be a single, integral structure and can include an outer concentric wall 1506a, an intermediate concentric wall 1504a, and an inner concentric wall 1514a. The inner concentric wall 1514a can be positioned within the intermediate concentric wall 1504a, which can be positioned within the outer concentric wall 1506a within the first connector portion 1508. The sealing member 1509a can be formed of a flexible or semi-flexible material. The first connector outer housing 1515a can be formed of, for example, a rigid or semi-rigid material. In one embodiment, the sealing member may be molded, additively manufactured, extruded, and / or machined from any one or combination of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic vulcanizate (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam, and / or open-cell PE foam, or the like. For example, the outer housing 1515a may be molded, additively manufactured, and / or machined from any one or combination of polyvinyl chloride (PVC), polyurethane, acrylonitrile butadiene styrene (ABS), or the like.

[0079] 15c, examples of fluid paths are described below. First connector portion 1508 can have tubing connection section 1585a, and second connector portion 1510 can have tubing connection section 1585b. First connector portion 1608 can have tubing connection portion 1685, which can be removably or permanently connectable to, for example, tubing 112b, 112c, and / or 112a of FIG. 1, tubing 212 or 213 of FIGS. 2a and 2b, tubing 422a-422c of FIGS. 4a-4b, tubing 722a-722c of FIGS. 7a-7b, or tubing 913 and / or 942 of FIGS. 9a and 9r. In some embodiments, the outer concentric wall 1506 a, the intermediate concentric wall 1504 a, and the inner concentric wall 1514 a of the first connector portion 1508 can be adapted (i.e., sized) to engage with the outer concentric wall 1506 b, the intermediate concentric wall 1504 b, and the inner concentric wall 1514 b of the second connector portion 1510 shown in FIG. 15 c to form a reversible connector 1520 in an engaged configuration. The foregoing configuration allows the first connector portion 1508 and the second connector portion 1510 to be connected in a first configuration (e.g., as shown in FIG. 15 c) to follow a first fluid flow channel within the connector, or in a second engaged configuration (e.g., a “reversed” configuration) to follow a second fluid flow channel, without changing the path order of fluid communication of the three separate fluid paths (e.g., paths 1, 2, and 3). When the connection is "reversed" (e.g., one of the first connector 1508 or the second connector 1510 is flipped 180 degrees), fluid paths 1, 2, and 3 of the first connector 1508 and the second connector 1510 are still aligned due to the concentric wall arrangement described above.

[0080] 15a and 15b, the first connector portion 1508 and the second connector portion 1510 may have respective first and second connector engaging portions 1516a and 1516b. The first connector engaging portion 1516a may be configured to fit within the second connector engaging portion 1516b. The engagement between the first and second connector engaging portions 1516a and 1516b may function as a guide for connecting the first connector portion 1508 to the second connector portion 1510, for example.

[0081] In one example, the first connector portion 1908 can have one or more locking features 1541a (one locking feature 1541a is hidden in FIG. 15a) configured to lockingly engage with one or more locking features 1541b of the second connector portion. In one example, the one or more locking features 1541b of the second connector portion can be openings sized to receive each of the locking features 1541a of the first connector portion 1508. In one aspect, the locking features 1541a and 1541b of the first and second connector portions can include the features described in FIGS. 12a-13b above. In the example shown, the locking feature of the first connector portion 1541a includes at least one pressing portion. The pressing portion of the locking mechanism 1541 a of the first connector 1508 may be biased or otherwise tensioned such that pressing the pressing portion moves the locking portion 1541 a into or out of engagement with the locking portion 1541 b of the second connector 1510. In one embodiment, the first The pressing or locking portion 1541 a of the connector 1508 may be connected to the first connecting portion via a plastic biasing member or other element configured to plastically deform or deflect when a user presses the locking portion. The second connector locking mechanism may include, for example, one or more openings 1541 b configured to lockingly receive the locking portion 1541 a of the first connector portion 1508. When a user desires to remove the first connector portion 1908 from the second connector portion 1520, applying a pressing force to the pressing portion of the locking portion 1541 a moves the locking portion 1541 a downward, disengaging it from the one or more openings of the locking portion 1541 b of the second connector portion, thereby allowing the user to separate the first connector portion 1508 from the second connector portion 1520. Any one of the locking mechanisms described above may include a visual, tactile, and / or audible indicator to indicate to the user that the connector is properly connected. One example of a visual indicator is further described with respect to Figures 12a and 12b above.

First connector portion 1608 may include, for example, main body portion 1615a. First connector portion 1608 may further include first sealing portion 1642a, second sealing portion 1642b, and / or third sealing portion 1642c. Each of the first sealing portion 1642a, the second sealing portion 1642b, and / or the third sealing portion 1642c may be comprised of, for example, a seal (e.g., an O-ring or other flexible seal) housed within a respective channel in the main body portion 1615a of the first connector portion 1608.

[0083] As shown in Figures 16b and 16c, the first connector portion 1608 is When engaged with the second connector portion 1610, interaction between the first sealing portions 1642a, 1642b, and 1642c and the inner sealing portion 1616 of the second connector portion 1608 forms a first chamber 1604 between the first sealing portion 1642a and the second sealing portion 1642c corresponding to the first opening 1646b of the first connecting portion, and a second chamber 1602 between the first sealing portions 1642b and 1642c corresponding to the second opening 1646c. The first chamber 1604 and the second chamber 1602 allow fluid, e.g., air, to pass from the first connector portion 1608 to the second connector portion 1610. The first connector and the second connector may additionally include third openings 1646a and 1647a, respectively, that are in direct fluid communication when the first connector portion 1608 is connected to the second connector portion 1610.

[0087] 19a-19c are pressure charts showing the pressure in each bladder (e.g., bladders 106a, 106b, and 106c of FIG. 1) of a compression garment provided through a reversible connector versus time during operation of a controller (e.g., controller 102 of FIG. 1 or controller 902 of FIGS. 9q-9s). The fluid pathways within the connectors described throughout this disclosure provide consistent performance when the connectors are connected in a first configuration 1900a and / or a second configuration 1900b (e.g., when one of the two connectors or connector portions is flipped 180 degrees). For example, the fluid pressure chart in FIG. 19b shows the fluid pressure provided through the first fluid path (1), the second fluid path (2), and the third fluid path (3) when the first connector portion 1908 is connected to the second connector portion 1910 in the first orientation.

As shown, switching either the first connector portion 1908 and / or the second connector portion 1910 from the first orientation to the second orientation has only a negligible effect on the pressure provided to each bladder by the controller through the reversible connector. In a preferred configuration, the first connector portion 1908 and / or the second connector portion 1910 are similar to the first connector portion 908 and the second connector portion 910, and / or the third connector portion 912 and the controller connector portion 944, described above with respect to FIGS. 9a-9s.In another aspect, first connector portion 1708 and second connector portion may be similar to or include features of controller-side first connector portion 108a and sleeve-side reversible second connector portion 110a shown in Figure 1, first connector portion 308 and second connector portion 310 shown in Figures 3A-3C, first connector portion 408 and second connector portion 410 shown in Figures 4A-4B, first connector portion 508 and second connector portion 510 shown in Figures 5A-5C, first connector portion 708 and second connector portion 710 in Figures 7A-7B, and / or first connector portion 808 and second connector portion 810 in Figures 8A-8D.
