Description

Technical Field

[0001] (Cross - Reference to Related Applications) This application claims priority to U.S. Provisional Application No. 63 / 028,819, filed on May 22, 2020, and entitled "SYSTEM, METHOD, AND DEVICE UTILIZING REVERSIBLE CONNECTOR". The entire 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 a system, method, and device for inflating a compression garment from a fluid source connected via a reversible connector, the reversible connector providing a unidirectional fluid flow through a plurality of fluid channels when the reversible connector is connected in either a first orientation or a second orientation.

Background Art

[0003] A vascular compression system includes a compression garment fluid - connected to a fluid source for periodically inflating the compression garment when the compression garment is worn on a patient's limb. Periodic inflation of the compression garment enhances blood circulation and reduces the likelihood of deep vein thrombosis (DVT). A controller controls the operation of the fluid source to deliver a fluid, such as air, to the 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, such as air, to a compression garment via piping that may include, for example, three separate tubes. Typically, a connector connects the piping extending from the controller (i.e., controller piping) to the piping extending from the compression garment (i.e., garment piping). The garment piping 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. Because the three tubes in the piping are in close proximity, the connector must be appropriately sized to allow the fluid, such as air, to pass through while limiting the separation of the three tubes. Typically, the three tubes in the piping are joined together side by side. Conventional connectors used to connect the controller piping to the garment piping can only be connected in a single orientation. In some implementations, the connector cannot connect in two or more orientations, or when connected in a second orientation, it cannot provide fluid connection to all three tubes, which may lead to improper functioning of the compression system and / or cause harm or discomfort to the patient. Therefore, in the art there is a need for a connector that connects all tubes (e.g., two, three, four or more) of the controller piping and garment piping in two or more orientations (e.g., linear orientation and reverse orientation), while providing fluid flow in a unidirectional direction from the controller's fluid source to the compression garment, regardless of the connection orientation, thereby ensuring proper functioning of the compression system and avoiding the possibility of causing discomfort or harm to the patient. [Overview of the project]

[0005] Aspects of this disclosure include a compression garment that is selectively engageable and operable by a controller for expansion via a reversible connector. The compression garment comprises a plurality of bladders and a plurality of garment chains that are in fluid communication with the plurality of bladders at a first compression garment piping end. The system comprises a compression garment piping including a tube, a second compression garment piping end provided on the opposite side of the first compression garment piping end, and a first connector portion located at the second compression garment piping end. The controller comprises a controller piping having a plurality of controller tubes that control communication with a source of fluid flow and selectively communicate with a source of fluid flow at the first controller piping end. The controller piping also includes a second controller piping end on the opposite side of the first controller piping end, and includes a second connector portion located at the second controller piping end. The first connector portion of the garment piping and the second connector portion of the controller piping are both selectively and reversibly connectable to form a reversible connector. A plurality of fluid flow passages extend within each of the first and second connector portions to form a first fluid flow passage when the first connector portion is coupled to the second connector portion in a first orientation. Multiple fluid flow passages in the first and second connector portions cooperate to form a second fluid flow channel when the first connector portion is coupled to the second connector portion in a second orientation. The fluid flow between the first controller tube among the plurality of controller tubes and the first compression garment tube among the plurality of compression garment tubes is communicated in a first fluid flow direction via the first fluid flow channel when the first and second connector portions are connected in a first orientation. The fluid flow through the first compression garment tube among the plurality of compression garment tubes and the first controller tube among the plurality of controller tubes is communicated in a first fluid flow direction via the second fluid flow channel when the first and second connector portions are connected in a second orientation.

[Modes for carrying out the invention]

[0011] Various embodiments are described here in more detail with reference to the drawings. In the following description, numerous specific details are given for illustrative purposes to provide a complete understanding of one or more embodiments. However, it may be apparent that such embodiments can be implemented without these specific details. Additionally, the term “component” as used herein may refer to one of the parts constituting a system, which may be hardware, firmware, and / or software stored on a computer-readable medium, and which may be divided into other components.

[0012] The following description provides examples and does not limit the scope, applicability, or examples described in the claims. Modifications may be made to the function and arrangement of the elements considered without departing from the scope of this disclosure. Various examples may omit, substitute, or add various procedures or components as needed. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Also, mechanisms described in some examples may be combined in other examples.

[0013] The term "reversible" is used throughout this disclosure as a modifier for a connector or a set of connectors. Contextual embodiments of the term "reversible connector" include a connector or set of connectors that can be connected in at least two different orientations (e.g., "reversed" or rotated 180 degrees around an axis) without affecting the order of bladder expansion in a compressed garment. The aforementioned embodiments are in contrast to irreversible connectors, where reversing the connection orientation (e.g., rotating the connector 180 degrees around an axis) affects the order of bladder expansion in a compressed garment.

[0014] Referring to the figures, similar reference numerals refer to similar components, and Figure 1 shows an exemplary compression system 100, the various mechanisms of which are available according to embodiments of the present disclosure, and the compression system 100 includes a controller 102, a compression garment 104, and one or more reversible connectors 120. As shown in Figure 1, the compression garment 104 is a sleeve The controller 102 may be connected by directly connecting the reversible second connector portion 110a on the controller side to the reversible first 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 provides additional distance between the controller 102 and the compression garment 104 and / or may accommodate different connectors (e.g., having different engagement mechanisms with fluid passage configurations) on either or both of the controller 102 and / or the compression garment 104. Throughout this disclosure, the terms adapter and extension may be used interchangeably. In one embodiment, the extension 119 may include, for example, a first reversible connector portion 108b at one end and a second reversible connector portion 110b at its second end, and a connecting pipe 112c provides a fluid connection between the two connector portions. The first reversible connector portion 108b and the second reversible connector portion 110b may be similar, for example, to the controller-side reversible first connector portion 108a and the sleeve-side reversible second connector portion 110a, respectively. Furthermore, specific embodiments of connecting the compression garment 104, the controller 102, and / or the adapter 119 are shown, but those skilled in the art will understand that any of the connector portions or connection mechanisms described herein may be used in any known method or configuration for connecting the controller 102 to the compression garment 104. Furthermore, any one of the controller-side reversible first connector portion 108a, the sleeve-side reversible second connector portion 110a, the first reversible connector portion 108b, and / or the second reversible connector portion 110b, or any combination thereof, may be referred to throughout this disclosure simply as interchangeable with the first connector portion or the second connector portion.

[0015] Figure 1 shows an embodiment of a compression garment 104, including a first connector portion 108 and a second connector portion 110 shown in an unconnected configuration. The compression garment 104 is configured to apply continuous compression therapy to the limb of a wearer, for example, a medical patient requiring 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 a plurality of bladders capable of containing a fluid such as air. For example, the compression garment 104 may include a distally inflatable bladder 106a, an intermediately inflatable bladder 106b, and a proximally inflatable bladder 106c. While three bladders are referenced herein, it is evident that fewer or more bladders may be used, such as one, two, or four, and as will be described in more detail below, the reversible connector 120 in 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 ties, 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 and control the operation of the compression garment 104 to perform a compression cycle, in which the inflatable bladder 106a, 106b, 106c is inflated to apply pressure to the wearer's limb, establishing a pressure gradient applied to the limb by controlling the fluid in the inflatable bladder 106a, 106b, 106c of the compression garment 104 during one or more compression cycles. For the purpose of describing exemplary operation of the compression system 100, after each compression cycle, a ventilation cycle may follow in which the pressure in each of the inflatable bladder 106a, 106b, 106c is released. The compression cycle and the ventilation cycle together form one complete therapeutic cycle of the compression system 100. The compression system 100 may measure the pressure gradient applied by the inflatable bladder 106a, 106b, 106c and make adjustments based on this measured pressure gradient. In some embodiments, the compression system 100 may not measure the pressure gradient. The compression system 100 may not adjust the pressure gradient based on the measurement during operation. 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, a middle 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, and 106c can expand and contract under the influence of a fluid (e.g., air or other fluid) delivered from a pressurizing fluid source via a controller 102. The controller 102 can deliver the pressurizing fluid from the fluid source to the inflatable bladders 106a, 106b, and 106c. A pressurized fluid source can deliver pressurized fluid to inflatable bladder 106a, 106b, 106c through a reversible first connector portion 108a on the controller side, the first connector portion 108a being connected to the controller 102 via controller piping 112a and / or forming part of the controller body (e.g., as shown in Figures 9q to 9s), the reversible connector 120, and the compression garment tube 112b. As will be described in more detail below, the reversible connector 120 may include a first connector portion 108a on the monitor side and a second connector portion 110a on the compression garment side, and / or include an adapter 119 having a first reversible connector portion 108b, a second reversible connector portion 110b, and connecting piping 112c. The first connector portion 108 may be connected to one end of the controller piping 112a (the other end of which is connected to the controller 102), and the second connector portion 110 may be connected to one end of the compression garment piping 112b (the other end of which is connected to the compression garment 104). Although Figure 1 shows only a single first connector portion 108 and second connector portion 110, embodiments of the present disclosure can be used with extension tube sets (e.g., piping of a certain length having connectors at either end) and / or adapters (e.g., piping of a certain length having a first type connector at the first end and a second type connector at the second end). Several non-limiting embodiments of the adapter are described below with reference to Figures 17 and 18.In addition, although not visible in Figure 1, any one or a combination thereof of the connectors described herein may be used to provide a controller-side connection between the controller 102 and any one or a combination thereof of the adapter, extension tube set, and / or compression garment 104. Several embodiments of the controller-side connection are described in further detail below with respect to Figures 9q to 9s.

[0018] Figure 2a shows a cross-section of an exemplary piping 212 that may be used between a controller-controlled fluid source and a compression sleeve according to an aspect of the present disclosure. In an uncoupled configuration, piping 212 may be similar to the controller piping 112a and compression garment piping 112b shown in Figure 1 and may include three separate tubes or piping passages or conduits 222a, 222b, 222c (such tubes, passages, or conduits are interchangeably referred to herein as “tubes”), and separate tubes for each of the inflatable bladders 106a, 106b, 106c of the compression garment 104 shown in Figure 1. In some aspects, piping 212 may be a smooth piping having three separate tubes 222a, 222b, 222c housed in piping 212 formed as a single piece, for example. In other aspects, piping 212 may comprise three separate tubes 222a, 222b, and 222c, each formed as a separate piece. The pipe 212 may be flexible. The pipe 212 may be made of polyvinyl chloride (PVC), polyurethane, or compression garment 1 as shown in Figure 1. It can be made from any suitable material for delivering fluid to 04. As will be described in more detail below, the reversible connector 120 in various aspects of the present disclosure may have piping 212 including three separate tubes 222a, 222b, 222c as shown in Figure 2, or more / less separate tubes 222a, 222b, 222c, e.g., a single tube Whether or not it includes a tube (not shown), two tubes (not shown), or four or more tubes (not shown), the compression garment 104 is configured to operably engage and connect to the controller 102.

[0019] Figure 2b shows a cross-section of another exemplary implementation of piping 213 that may be used between a controller-controlled fluid source and a compression garment according to an aspect of the present disclosure. Any one or any combination of the piping outlines shown in Figure 2a and / or Figure 2b may be implemented to create a fluid path between each of the connector and / or sleeve (e.g., sleeve 100 in Figure 1) and / or controller (e.g., controller 102 in Figure 1). For example, piping 212 may be used as controller piping 112a and compression garment piping 112b shown in Figure 1. Piping 213 may be flexible. Piping 213 may be made from polyvinyl chloride (PVC), polyurethane, or any suitable material for delivering fluid to the compression garment 104 shown in Figure 1. In a preferred embodiment, the material of piping 213 may be flexible or semi-flexible but maintain sufficient rigidity to prevent twisting or constriction of the tube (thus blocking the fluid flow). The piping 213 may include three separate tubes or piping passages or conduits 223a, 223b, and 223c, which may correspond to and create fluid paths between the controller (e.g., controller 102 in Figure 1) and the three bladders 106a, 106b, and 106c of the compression garment 104. While three tubes or piping passages or conduits 223a, 223b, and 223c are shown and three bladders are provided as embodiments, aspects of the present disclosure may include more or fewer passages corresponding to the number of inflatable bladders. For example, the piping may include two passages providing fluid communication to two bladders, or four or more passages providing fluid communication to a corresponding number of bladders. For example, in one exemplary implementation, the piping may include four to six passages. In one modified example, the piping 213 has an external shape as shown in Figure 2b and can create a fluid path between, for example, any one or a combination thereof of the connectors, compression garments 104, and / or controllers 102 described throughout this disclosure. In some embodiments, the piping 212 may be similar to the piping described above with respect to Figure 2a, but may include an additional alignment section 221. The alignment section may include, for example, an additional passage or alignment mechanism comprising a first alignment section 224 and a second alignment section 225.One function of the alignment section 221 may be to ensure that the piping 213 is installed in the correct orientation (e.g., not "inverted") for any one of the connectors described throughout this disclosure. An exemplary implementation of the alignment section 221 and the interaction between the alignment section 221 and the corresponding part of the connector (e.g., during assembly of the piping and the connector) are described below with reference to Figures 10 and 11.

[0020] Figure 2c shows a cross-section of an exemplary piping 214 that may be used between a controller-controlled fluid source and a compression sleeve according to an aspect of the present disclosure. In an uncoupled configuration, piping 214 may be similar to the controller piping 112a and compression garment piping 112b shown in Figure 1 and may include three separate tubes or piping passages or conduits 224a, 224b, 224c (such tubes, passages, or conduits are interchangeably referred to herein as “tubes”), and separate tubes for each of the inflatable bladder 106a, 106b, 106c of the compression garment 104 shown in Figure 1. In some embodiments, piping 212 may be a smooth piping having three separate tubes 224a, 224b, 224c housed in piping 214 formed as a single piece, for example. In other embodiments, piping 212 may comprise three separate tubes 224a, 224b, and 224c, each formed as a separate piece. The pipe 214 may be flexible. The pipe 214 may be made from polyvinyl chloride (PVC), polyurethane, or any suitable material for delivering fluid to the compression garment 104 shown in Figure 1. In a preferred embodiment, the material of the pipe 214 may be flexible or semi-flexible, but maintain sufficient rigidity to prevent twisting or constriction of the tube (thus blocking the fluid flow). In one embodiment, the pipe 214 is flexible Alternatively, they may be formed by extruding or molding a semi-flexible material. As will be described in more detail below, the reversible connector 120 in various aspects of the present disclosure is configured to operably engage and connect a compression garment 104 to a controller 102, whether the piping 212 includes three separate tubes 222a, 222b, 222c shown in Figure 2a, 223a, 223b, 223c shown in Figure 2b, and 224a, 224b, 224c shown in Figure 2c, or more / fewer separate tubes 224a, 224b, 224c, for example, a single tube (not shown), two tubes (not shown), or four or more tubes (not shown).

[0021] Figure 3a shows an exemplary reversible connector 320 having a first connector portion 308 and a second connector portion 310 (hereinafter referred to herein as "connector components" or "connector portions") in a connected configuration (such a connected configuration is also interchangeably referred herein as an "engaged" or "coupled" configuration) according to an aspect of the present disclosure. The first connector portion 308 and the second connector portion 310 may be analogous to the first connector portion 108 and the second connector portion 110 shown in Figure 1. It will be recognized that the first connector portion 308 and the second connector portion 310 may be connected via different types of engagement mechanisms, including, among other types of engagement, mechanisms for providing sliding engagement, compression fitting, snap fitting and magnetic engagement. Additional embodiments of engagement mechanisms are described below with respect to Figures 5 to 9s, 12a to 13b and 15a to 15b.

[0022] As shown in Figure 3b, the first connector portion 308 may include an outer concentric wall 306a, an intermediate concentric wall 304a, and an inner concentric wall 314a. The inner concentric wall 314a may be positioned within the intermediate concentric wall 304a, and the intermediate concentric wall 304a may be positioned within the outer concentric wall 306a of the first connector portion 308.

[0023] Referring next to Figure 3c, the second connector portion 310 may include an outer concentric wall 306b, an intermediate concentric wall 304b, and an inner concentric wall 314b. The inner concentric wall 314b may be positioned within the intermediate concentric wall 304b, and the intermediate concentric wall 304b may be positioned within the outer concentric wall 306b of the second connector portion 310.

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

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

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

[0027] Figures 3a and 3b show the outer concentric walls 306a and 306b and the intermediate concentric walls 304a and 304b of the first connector portion 308 and the second connector portion 310 as rectangular, and the inner concentric walls 314a and 314b of the first connector portion 308 and the second connector portion 310 as circular. However, it should be noted that the embodiments of this disclosure are not limited to the configurations described in more detail herein (for example, all walls may be rectangular, square, elliptical, or circular).

[0028] Referring again to Figures 3a and 3b, each of the outer concentric wall 306a, intermediate concentric wall 304a, and inner concentric wall 314a of the first connector portion 308 may extend from the base 302a of the first connector portion 308. Each of the outer concentric wall 306b, intermediate concentric wall 304b, and inner concentric wall 314b of the second connector portion 310 may extend from the base 302b of the second connector portion 310. The height of the concentric walls, i.e., the distance the concentric walls extend away from the bases 302a and 302b, can be appropriately sized to form corresponding chambers 402, 404, and 406 (as illustrated in Figures 4a and 4b) for each of the concentric walls when the first connector portion 308 is engaged or connected to the second connector portion 310 (e.g., via sliding engagement, compression fitting, snap fitting, and magnetic engagement, among other types of engagement means). For example, when the first connector portion 308 is slidably engaged with the second connector portion 310, the outer concentric wall 306a of the first connector portion 308 and the outer concentric wall 306b of the second connector portion 310 form chamber 402 (shown in Figures 4a and 4b), allowing a fluid, such as air, to pass from the first connector portion to the second connector portion. In another embodiment, when the first connector portion 308 is slidably engaged with the second connector portion 310, the intermediate concentric wall 304a of the first connector portion 308 and the intermediate concentric wall 304b of the second connector portion 310 form a chamber 404 (shown in Figures 4a and 4b), allowing a fluid, such as air, to pass from the first connector portion to the second connector portion. In yet another embodiment, when the first connector portion 308 is slidably engaged with the second connector portion 310, the inner concentric wall 314a of the first connector portion 308 and the inner concentric wall 314b of the second connector portion 310 form a chamber 406 (shown in Figures 4a and 4b), allowing a fluid, such as air, to pass from the first connector portion to the second connector portion.The height of the concentric walls can be sized so that the formed chambers 402, 404, and 406 fluidly connect the first connector portion 308 to the second connector portion 310, and each of the formed chambers 402, 404, and 406 (shown in Figures 4a and 4b) provides a seal that prevents little or no fluid leakage, thereby forming a cooperative fluid flow connection channel.

[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). As shown in Figure 3b, for example, the height of the long side of the outer concentric wall 306a may be lower 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 and short sides is due to the engagement of the first connector portion 308 with the second connector portion 310. When forming the reversible connector 320 into an engagement configuration, greater flexibility can be enabled.

[0030] Referring again to Figures 3a and 3b, in the first connector portion 308, the fluid passage 324a may be formed in the intermediate concentric wall 304a, the fluid passage 324b may be formed in the intermediate concentric wall 304a, and the fluid passage 324c may be formed by the inner concentric wall 314a. In the second connector portion 310, the fluid passage 326a may be formed in the intermediate concentric wall 304b, the fluid passage 326b may be formed in the intermediate concentric wall 304b, and the fluid passage may be formed by the inner concentric wall 314b. One or more of the fluid passages 324a, 324b formed in the intermediate concentric wall 304a of the first connector portion 308, and / or one or more of the fluid passages 326a, 326b formed in the intermediate concentric wall 304b of the second connector portion 310 may include bumpouts 328a, 328b, 330a, 330b for guiding or reflecting fluid, such as air, within the 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 will be described in more detail below.

[0031] Figures 4a and 4b are top cross-sectional views of embodiments of a reversible connector in a first and second orientation, illustrating the fluid flow in each orientation. When the first connector portion 408 engages with the second connector portion 410, each of the corresponding concentric walls forms corresponding chambers 402, 404, and 406, allowing a 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 analogous 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 Figures 1 and 3a-3c. For example, the outer concentric wall 406a of the first connector portion 408 may slide within the outer concentric wall 406b of the second connector portion 410 to form an outer chamber 402. In another embodiment, the intermediate concentric wall 404a of the first connector portion 408 may slide within the intermediate concentric wall 404b of the second connector portion 410 to form an intermediate chamber 404. In yet another embodiment, the inner concentric wall 414a of the first connector portion 408 may slide within the inner concentric wall 414b of the second connector portion 310 to form an inner chamber 406. The outer concentric walls 406a and 406b, intermediate concentric walls 404a and 404b, and inner concentric walls 414a and 414b of the first connector 408 and the second connector 410 are similar to the outer concentric walls 306a and 306b, intermediate concentric walls 304a and 304b, and 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 Figure 4a, in a first orientation of the reversible connector 420 (similar to the reversible connectors 120 and 320 shown in Figures 1 and 3a), when the first connector portion 408 engages with the second connector portion 410 in the first orientation, the outer chamber 402 may be formed by substantially aligned fluid passages 324a and 326a shown in Figures 3b and 3c, the intermediate chamber 404 may be formed by substantially aligned fluid passages 324b and 326b shown in Figures 3b and 3c, and the inner chamber 406 may be formed by substantially aligned fluid passages 324c and 326c shown in Figures 3b and 3c. As shown in Figures 3b and 3c, fluid passages 324a and 326a can be substantially aligned with adjacent bumpouts 328a and 330a to form an outer chamber 402 (shown in Figure 4a), and fluid passages 324b and 326b can be substantially aligned with adjacent bumpouts 328b and 330b to form an intermediate chamber 404 (shown in Figure 4a). Thus, in the first orientation, the reversible connector 420 is similar to the three tubes 422a, 422b, and 422c (tubes 222a, 222b, and 222c shown in Figure 2a, 223a, 223b, and 224a, 224b, and 224c shown in Figure 2c) of the controller piping 412a (which may be similar to the controller piping 112a shown in Figure 1). The controller piping 412a receives a fluid, such as air, and supplies it to the three tubes 422a, 422b, and 422c of the garment piping 412b (similar to the compression garment piping 112b shown in Figure 1). The fluid flow from the three tubes 422a, 422b, and 422c of the controller piping 412a to the three tubes 422a, 422b, and 422c of the garment piping 412b forms a fluid connection channel in the first orientation of the reversible connector 420, as indicated by arrows 430a, 430b, and 430c. According to 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) with fewer than three inflatable bladders, for example. Although shown as separate tubes in the embodiments of Figures 3A to 4B, in an alternative embodiment, tubes 422a, 422b, and 422c may be similar to any one or a combination thereof of passages 222a, 222b, and / or 222c of piping 212 in Figure 2a, and / or passages 223a, 223b, and / or 223c of piping 213 in Figure 2b, and / or passages 224a, 224b, and / or 224c of piping 214 in Figure 2c.

[0033] As illustrated in Figure 4b, in a second orientation of the reversible connector 420 (similar to the reversible connectors 120 and 320 shown in Figures 1 and 3a), when the first connector portion 408 engages with the second connector portion 410 in the second orientation, the outer chamber 402 may be formed by offset fluid passages 324a and 326a shown in Figures 3b and 3c, the intermediate chamber 404 may be formed by offset fluid passages 324b and 326b shown in Figures 3b and 3c, and the inner chamber 406 may be formed by offset fluid passages 324c and 326c shown in Figures 3b and 3c. As shown in Figures 3b and 3c, the fluid passages 324a and 326a may be offset from each other, and the bumpouts 328a and 330a may be offset from each other to form the outer chamber 402 (shown in Figure 4a), and the fluid passages 326a and 326b may be offset from each other, and the bumpouts 328b and 330b may be offset from each other to form the intermediate chamber 404 (shown in Figure 4a). As a result, in the second orientation, the reversible connector 320 receives fluid, such as air, from three tubes 422a, 422b, and 422c (which may be similar to tubes 222a, 222b, and 222c shown in Figure 2a, 223a, 223b, and 223c shown in Figure 2b, and 224a, 224b, and 224c shown in Figure 2c) of the controller piping 412a (similar to controller piping 112a shown in Figure 1), and respectively supplies fluid, such as air, to three tubes 422c, 422b, and 422a of the garment piping 412b (similar to compression garment piping 112b shown in Figure 1). The fluid flow from the three tubes 422a, 422b, and 422c of the controller piping 412a to the respective three tubes 422c, 422b, and 422a of the garment piping 412b forms a fluid connection channel in the second orientation of the reversible connector 420, as indicated by arrows 430, 430b, and 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 the opposite end of the base 302a shown in Figure 3b, from which concentric walls 306a, 304a, and 314a extend. In the second connector portion 410, the three inlets 418a, 418b, and 418c extend from the opposite end of the base 302b shown in Figure 3c, from which concentric walls 306b, 304b, and 314b extend. Each of the inlets 416a, 416b, 416c, 418a, 418b, and 418c may be adapted to receive the corresponding tube from the piping 412a and 412b on the outer edge of the inlets 416a, 416b, 416c, 418a, 418b, and 418c. For example, three inlets 4 Each of 16a, 416b, and 416c may be adapted to receive a corresponding tube from controller piping 412a, and each of the three inlets 418a, 418b, and 418c may be adapted to receive a corresponding tube from garment piping 412b. In the first orientation, for example, each of the three inlets 416a, 416b, and 416c may be adapted to receive a corresponding tube 422a, 422b, and 422c from controller piping 412a, and each of the three inlets 418a, 418b, and 418c may be adapted to receive a corresponding tube 422a, 422b, and 422c from garment piping 412b. Conversely, in the second orientation, for example, each of the three inlets 416a, 416b, and 416c may be adapted to receive the corresponding tubes 422a, 422b, and 422c from the controller piping 412a, and each of the three inlets 418a, 418b, and 418c may be adapted to receive the corresponding tubes 422c, 422b, and 422a from the garment piping 412b.

[0035] In some embodiments, 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 similar materials. The flexible material may be made from liquid silicate It can be made from liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), or similar materials. By fabricating the connector portion 408 from a rigid material and the second connector portion 410 from a flexible material, connecting the first connector portion 408 and the second connector portion 410 may be easier than if the first connector portion 408 and the second connector portion 410 were made from the same material, due to the flexibility of the second connector portion 410. However, in other embodiments, the first connector portion 408 and the second connector portion 410 may be made from the same material.

[0036] Referring again to Figures 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 in Figure 1, and the first connector portion 408 and the second connector portion 410 in Figures 4a and 4b) may include, for example, contact pads 332 on the outer concentric walls 306a, 306b, such as grips, anti-slip grips, or textured grips. 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 embodiment, the second connector portion 310 may include contact pads 332 on the top and / or bottom of the outer concentric wall 306b. The contact pad 332 can assist in connecting the first connector portion 308 and the second connector portion 310 by providing a non-sliding surface.The material of the contact pad may be the same as the material of the connector parts 308 and 310, namely, 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 (Liquid Crystal Polymer (LCP), Low-density Polyethylene (LLDPE), Linear Low-density Polyethylene (LLDPE), Ultra-high molecular weight polyethylene. It may be one or a combination of ultra-high-molecular-weight polyethylene (UHMW), or similar materials.

[0037] As illustrated in Figures 3a and 3b, the outer concentric walls 306a, 306b and 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 wall 314a of the first connector portion 308 and the inner concentric wall 314b of the second connector portion 310 may be circular or elliptical. In other embodiments of the present disclosure, the inner concentric wall 314a of the first connector portion 308 and the inner concentric wall 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] Figure 5a shows a perspective view of another embodiment of a reversible connector 520 according to an aspect of the present disclosure, with the first connector portion 508 and the second connector portion 510 in the engaged position. The first connector portion 508 and the second connector portion 510 are similar to the first connector portion 108 and the second connector portion 110 shown in Figure 1, the first connector portion 308 and the second connector portion 310 shown in Figures 3a to 3c, and the first connector portion 408 and the second connector portion 410 shown in Figures 4a to 4b. In this embodiment, the first connector portion 508 and the second connector portion 510 may have an elliptical or circular outer shape.

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

[0040] In some embodiments, the outer concentric wall 506a, the intermediate concentric wall 504a, and the inner concentric wall 514a of the first connector portion 508 may 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, and 514a. The concentric walls 504a, 504b, 514a, and 514b are analogous 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 the outer concentric wall 506a can receive the sealing member 542a, the recess in the intermediate concentric wall 504a can receive the sealing member 542b, and the recess in the inner concentric wall 514a can receive the sealing member 542c. Perspective views of the sealing members 642a, 642b, and 642c (similar to the sealing members 542a, 542b, and 542c shown in Figure 5b) are also illustrated in Figure 6.

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

[0042] The sealing members 642a, 642b, and 642c shown in Figure 6 are part of the first connector portion 7 When 08 engages with the second connector portion 710 to form a reversible connector 720, it may help create a seal for each of the corresponding chambers 702, 704, and 706 (shown in Figures 7a and 7b). By using sealing members 642a, 642b, and 642c, shown in Figure 6, it may be possible to connect the first connector portion 708 and the second connector portion 710 more easily when they are engaged. In some embodiments, the first connector portion 708 may be made from a rigid material, while the female connector portion 710 may be made from a flexible material. In other embodiments, the first connector portion 708 and the second connector portion 710 may be made from the same material.

[0043] Figure 7b shows another exemplary top cross-sectional view of a reversible connector 720 according to an aspect of the present disclosure, in which the first and second portions 708, 710 are in an engaged position and the first and second fluid flow connection channels, which cooperate with each other, are in a second orientation defining a second configuration that indicates the direction of fluid flow from the fluid source of the controller to the compression garment.

[0044] Figures 7a and 7b show a reversible connector 720 in which the first portion 708 and the second portion 710 are engaged in a first orientation and a second orientation, and the fluid flow is the same as the fluid flow illustrated in Figures 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. The first connector portion 808 and the second connector portion 810 are similar to the first connector portion 108 and the second connector portion 110 shown in Figure 1, the first connector portion 308 and the second connector portion 310 shown in Figures 3a to 3c, the first connector portion 408 and the second connector portion 410 shown in Figures 4a and 4b, and the first connector portion 708 and the second connector portion 710 shown in Figures 7a and 7b.

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

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

[0048] Figure 8d shows the gasket 860. The gasket 860 may be made from liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), or a similar material. The intermediate concentric wall 844 and the inner concentric wall 850 of the gasket 860 may replace the intermediate concentric wall 304b and the inner concentric wall 314b (shown in Figure 3c) of the embodiments of the present disclosure described above with respect to the second connector portion 310 (similar to the second connector portion 810). The intermediate concentric wall 844 of the gasket 860 may include fluid passages 846a, 846b, 846c that replace 326a, 326b, 326c (shown in Figure 3c) of the embodiments of the present disclosure described above with respect to the second connector portion 310. The intermediate concentric wall 844 may include bumpouts 848a, 848b that replace the bumpouts 330a, 330b (shown in Figure 3c) of the earlier embodiments of the present disclosure described above with respect to the second connector portion 310.

[0049] The use of sealing member 842a (shown in Figure 8a) can help create a seal for chamber 702 (shown in Figures 7a and 7b) when the first connector portion 808 is slidably engaged with the second connector portion 810, as shown in Figures 8a and 8b. The use of sealing member 842a and gasket 860 can make it easier to connect the first connector portion 808 and the second connector portion 810 when they are engaged.

[0050] According to another aspect of the present invention, referring back to Figures 4a and 4b, 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) with fewer than three inflatable bladders, for example. In such embodiments, the garment piping 412b may include only the tubes 422a, 422b, and 422c necessary to operate the compression garment according to this embodiment, for example, 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 tube 422a to any one of the inlets 416a, 416b, and 416c. During the setup and initialization cycle, the controller may individually deliver small amounts of pressurized fluid flow to each of the inlets 416a, 416b, and 416c and individually determine whether inlets 416a, 416b, and 416c are connected to tube 422a. If the controller determines that one or more of the inlets 416a, 416b, and 416c are not connected to tube 422a, the controller then supplies pressurized fluid only to the inlets where tube 422a is present. In this way, the reversible connector is adaptable for use with any combination of tubes 422a, 422b, and 422c connected to inlets 416a, 416b, and 416c.

[0051] Figures 9a to 9d show perspective views of exemplary reversible connectors according to embodiments of the present disclosure. Modifications may include a first connector portion 908, a second connector portion 910, and / or a third connector portion 912. The first connector portion 908, the second connector portion 910, and the third connector portion 912 are shown in a specific configuration in Figure 9a (i.e., the first connector portion 908 engages with the second connector portion 910, and the piping 913 connects the second connector portion 910 to the third connector portion 912), but the described connectors and embodiments are applicable to any configuration. In the embodiment shown in Figure 9a, the third connector portion 912 may be a controller connector configured to connect to a controller (e.g., controller 102 in Figure 1 above and / or controller 902 in Figures 9q to 9s below) and provide fluid communication. Furthermore, the first connector portion 908 connects to the inflatable bladder (e.g., bladder 106a, 106b, and / or 106c) of the compression garment (e.g., compression garment 104 in Figure 1) via the compression garment piping 942. This can provide fluid communication. As shown in Figure 9a, the third connector portion 912 and the second connector portion 910 may be connected via piping 913. Piping 913 provides fluid communication between the corresponding passages of the third connector portion 912 and the second connector portion 910. Piping 913 may have, for example, three separate passages or conduits 922a, 922b, and 922c inside. In one embodiment, piping 913 may be analogous to piping 212 or 213 described above with reference to Figures 2a and 2B or later to Figures 11a and 11b.

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

[0053] Figure 9a shows the first connector portion 908 connected to the second connector portion 910. Although not limited to the configuration described above, the first connector portion 908 may provide fluid communication with a compression garment (e.g., compression garment 104 in Figure 1) via, for example, a compression garment piping 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 in Figure 1 and / or controller 902 in Figures 9q-9s). Embodiments of the reversible connection portion on the controller side are described in detail below with respect to Figures 9q and 9s. Figure 9b shows a perspective view of the first connector portion 908, Figure 9c shows a perspective view of the second connector portion 510, and Figure 9d shows an embodiment of the third connector portion 912. Further details of the connector portions are described in detail below with respect to Figures 9e-9r and 12a-15b.

[0054] As illustrated, the first connector portion 908 may 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. Figure 9c shows a second connector portion 910 separated from the first connector portion 908. Note that the orientation of the second connector portion 910 in Figure 9c is for visual clarity and does not necessarily indicate the assembly orientation. As shown in Figure 9c, the second connector portion 910 may have an outer housing 915b, an outer sealing 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 (for example, as shown in Figure 9a), the outer wall 906a, intermediate concentric wall 904a, and inner concentric wall 914a of the sealing member 909a engage sealantly with the outer sealing engagement wall 906b, intermediate concentric wall 904b, and inner concentric wall 914b, respectively, creating 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 an inner concentric wall 914c. In some embodiments, 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 This may reduce production costs and / or facilitate the replacement or reprocessing of connectors and / or related devices (e.g., compression garments, adapters, extension devices, and / or controllers).

[0055] As shown in Figure 9e, the first connector portion 908 may include the first connector outer housing 915a. The outer housing 915a may be a separate component from the sealing member 909a, as shown in Figures 9f and 9g. Referring to Figure 9g, the sealing member 909a may be a single, integrated 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 connection portion, a second opening 992a corresponding to the second fluid passage 2 of the first connection portion 912, and a third opening 993a corresponding to the third fluid passage 3 of the first connection 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 one or more support structures (e.g., 929a in Figure 9g). The support structures may comprise sections of material having a larger cross-sectional area than the rest of the sealing member 909a, and may prevent any one or a combination of the first outer concentric wall 906a, the intermediate concentric wall 904a, and / or the inner concentric wall 914b from buckling at the interface between the first connector portion 908 and the second connector portion 910, or otherwise causing the seal to break or leak. The first connector outer housing 915a may be formed of, for example, a rigid or semi-rigid material. In Figure 9I, only a single support structure is referenced to avoid obstructing the figure, but any number of support structures may be used without departing from the scope of the present disclosure. For example, as shown in Figure 9l, 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 of the following: liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic vulcanisates (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam and / or open-cell PE foam, or a combination thereof.In a preferred embodiment, the 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 a combination thereof 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 (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 similar materials. In a preferred embodiment, the outer housing 915a is injection-molded acrylonitrile butadiene styrene (ABS).

[0056] Referring next to Figures 9h and 9i, the second connector portion 910 may 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 may be positioned within the intermediate concentric wall 904b, and the intermediate concentric wall 904b may 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 may be formed as a single integrated component. In one embodiment, the second connector outer housing 915b, the outer concentric wall 906b, the intermediate concentric wall 904b, and the inner concentric wall 914b may be formed from, for example, a rigid or semi-rigid material. For example, the second connector outer housing 915b, outer concentric wall 906b, intermediate concentric wall 904b, and inner concentric wall 914b are made of 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 (acetate). The connector may be molded, additively manufactured, extruded, and / or machined from any one or a combination thereof of acrylic / delrin, polypropylene (PP), 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 similar materials. In a preferred embodiment, the second connector outer housing 915b, outer concentric wall 906b, intermediate concentric wall 904b, and inner concentric wall 914b are injection-molded acrylonitrile butadiene styrene (ABS).

[0057] Referring next to Figure 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 Figures 9k and 9I. Referring to Figure 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, and the intermediate concentric wall 904c may be positioned within the outer concentric wall 906c within 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 connection portion, a second opening 992c corresponding to the second fluid passage 2 of the third connection portion 912, and a third opening 993c corresponding to the third fluid passage 3 of the third connection portion 912. The sealing member 909c may be formed of a flexible or semi-flexible material. The sealing member 909a may further include one or more support structures (e.g., 929c in Figure 9I). The support structure may comprise a section of material having a larger cross-sectional area than the rest of the sealing member 909a, and one or a combination thereof of the first outer concentric wall 906c, the intermediate concentric wall 904c, and / or the inner concentric wall 914c may prevent buckling, "bursting," or otherwise breaking the seal or causing leakage at the interface between the third connector portion and the connector connected thereto (e.g., the controller side or the fourth connector 941a and / or 941b in Figures 9q to 9s described below). In one embodiment, the third connector may be configured to connect to a connector having a mechanism similar to or identical to that of the second connector portion 910. In one embodiment, the sealing member 909c may be molded, additively manufactured, extruded, and / or machined from any one of the following: liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic vulcanized material (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam and / or open-cell PE foam, or a combination thereof.In a preferred embodiment, the 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 a combination thereof 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 (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 similar materials. , and / or can be 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 through which a tie-down portion or label connection portion passes. Further exemplary embodiments of the function of the tie-down portions are described below with reference to Figure 9r.

[0058] Next, with reference to Figures 9m and 9n, embodiments of the fluid path are described below. The first connector portion may include a pipe connection portion 985a, and the second connector portion may include a pipe connection portion 985b, which may be removable or permanently connected to, for example, pipes 112b, 112c, and / or 112a in Figure 1, pipes 212 or 213 in Figures 2a and 2b, pipes 422a to 422c in Figures 4a to 4b, pipes 722a to 722c in Figures 7a to 7b, and pipes 913 and / or 942 in Figures 9a and 9r.

[0059] The connectors referenced in Figures 9m and 9n are a first connector portion 908 and a second connector portion 910, but the same embodiments may be applicable to a third connector portion 912 and / or a fourth connector or controller-side connector (e.g., controller-side connectors 1914a and / or 1914b in Figures 19a and 19c). In some embodiments, the outer concentric wall 906a, the middle concentric wall 904a, and the inner concentric wall 914a of the first connector portion 908 may engage with the outer concentric wall 906b, the middle concentric wall 904b, and the inner concentric wall 914b of the second connector portion 910 shown in Figure 9e to be adapted (i.e., sized) to form a reversible connector 920 in an engaging configuration, as illustrated in Figures 9a, 9m, and 9n. For example, as shown in Figures 9m and 9n, the outer concentric wall 906a of the first connector portion 908 may engage with the outer surface of the outer concentric wall 906b of the second connector portion 910. The intermediate concentric wall 904a of the first connector portion 908 may engage with the outer surface of the intermediate concentric wall 904b of the second connector portion 910. Furthermore, as shown in Figure 9m, when the first connector portion 908 engages with the second connector portion 910 to form a reversible connector 920 in the first engagement configuration, the inner concentric wall 914a of the first connector portion 908 may engage with the outer surface of the inner concentric wall 914b of the second connector portion 910.

[0060] As shown in Figure 9n and further described below, the first connector portion 908 and the second connector portion 910 can be connected in a second engagement configuration (e.g., a “reversed” configuration) without changing the order of the fluid communication paths. For example, the first connector portion 908 may have a pipe connection portion 985a with three separate fluid paths (e.g., paths 1, 2, and 3). Similarly, the second connector portion 910 may have a pipe connection portion 985b with three separate fluid paths (e.g., paths 1, 2, and 3). As shown in Figure 9m, in the first engagement configuration, the respective orders of fluid paths 1, 2, and 3 of the first connector portion 908 and the second connector portion 910 are aligned and flow through the first fluid flow channel. As indicated by arrow 980, with the connection “reversed” (for example, with one of the first connector portion 908 or the second connector portion 910 reversed by 180 degrees), the fluid paths 1, 2, and 3 of the first connector portion 908 and the second connector portion 910 remain aligned while flowing through the second fluid flow channel, due to the concentric wall arrangement described above. Mechanisms such as the funnel portion 917, as will be described in more detail below with respect to Figures 19a to 19c, improve fluid flow and pressure consistency regardless of the orientation in which the first connector portion 908 and the second connector portion 910 are connected. As shown in Figures 9m and 9n, the first connector portion 908 and the second connector portion 910 may have a first connector engagement portion 916a and a second connector engagement portion 916b, respectively. The first connector engagement portion 916a may be configured to fit into the second connector engagement portion 916b. The engagement between the first connector engagement portion 916a and the second connector engagement portion 916b is, for example, a guide for connecting the first connector portion 908 to the second connector portion 910. It can function as a connector. In one embodiment, any one or a combination thereof of connector portions may have a locking mechanism to ensure a secure connection and sealing engagement between two or more connectors. One embodiment of such a mechanism is shown in Figures 9a to 9d. In the shown embodiment, 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 the locking portion 945a may be biased or otherwise tensioned such that pressing the pressing portion 944a causes the locking portion 945a to engage with or disengage from the locking portion 945b of the second connector portion 910. In one embodiment, the pressing portion 944a and / or the locking portion 945a may be connected to the first connector portion via a plastic biasing member or other element configured to plastically deform or flex when the user presses the locking portion. The second connector locking mechanism may include, for example, one or more openings 943 configured to reciprocally receive the locking portion 945a of the first connector portion 908. The aforementioned locking mechanism may, for example, lock the first connector portion 908 in place once the first connector portion 908 and the second connector portion are connected and sealed together. The first connector portion 908 and the second connector portion 910 may be locked together when the user pushes the first connector portion 908 into the second connector portion 910 until the locking portion 945a is reciprocally received within one or more openings 943. If the user wishes to detach the first connector portion 908 from the second connector portion 910, applying pressure to the pressing portion 944a moves the locking portion 945a downward, releasing the locking engagement with one or more openings 943, thereby allowing the user to separate the first connector portion 908 from the second connector portion 910. The third connector portion 912 may additionally include a similar mechanism including a pressing portion 944c and / or a locking portion 945c.Although not visible in Figure 9a, one or a combination of the first connector pressing portion 944a, the first connector locking portion 945a, and / or the second connector locking portion 945b, the connector locking portion 945a, and / or the lock 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 visual, tactile, and / or auditory indicators to show the user that the connector is properly connected. An embodiment of a visual indicator is further described below with reference to Figures 12a and 12b.

[0061] As shown in Figures 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 may be a friction fit or an interlocking fit type interface. For example, the outer concentric wall 906a of the first connector portion 908 may engage slidingly or frictionally with 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 may be formed of a material that is more flexible than the outer concentric wall of the second connector portion 910. In the above embodiment, the outer concentric wall 906a of the first connector portion 908 may have one or more inner dimensions that are substantially the same as or slightly smaller than those of the outer concentric wall 906b of the second connector portion 910. As a result, when the two connectors are connected by the user, the outer concentric wall 906a of the first connector portion 908 frictionally engages with the outer concentric wall 906b of the second connector portion 910, forming a seal between them that does not allow fluid loss at the interface or allows only minimal fluid loss. Similarly, the intermediate concentric wall 904a of the first connector portion 908 may slide or frictionally engage with the outer surface of the intermediate concentric wall 904b of the second connector portion 910. The inner concentric wall 914a of the first connector portion 908 may also slide or frictionally engage with the outer surface of the inner concentric wall 914b of the second connector portion 910 when the first connector portion 908 engages with the second connector portion 910 to form a reversible connector 920 in the first engagement 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 intermediate concentric wall 904a of the first connector portion and the intermediate 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 914 of the second connector portion 910 An enlarged view of the friction fit or interlock fit between b and b is shown in Figure 9p. The connector referenced above is the first connector portion 908 and the second connector portion 910, but the same embodiments may be applicable to the third connector portion 912 and / or the fourth connector or controller-side connector (for example, the controller-side connectors 941a and / or 941b in Figures 9q to 9s).

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

[0063] In the embodiment shown in Figure 9r, the reversible connector comprises a third connector portion 912 and a second connector portion 910, with piping 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 engage securely with the reversible connector (e.g., the third connector portion 912). One or both of the controller-side reversible connection portions 941a and / or 941b may have a locking mechanism comprising one or more locking portions 942a and / or 942b. The locking portions 942a and / or 942b may be configured to engage securely 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 embodiment, pressing the pressing portion 944c (Figure 9a) of the third connector portion releases the locking portion 945c from one or more locking portions 942a and / or 942b of the controller-side connection portion 944.

[0064] In one embodiment, the controller body or controller body connection portion may include monitor-side tie-down portions corresponding to each monitor-side connection portion 941a and / or 941b. The monitor-side tie-down portion 919 may be configured to allow a portion of a tie or label to pass through. In one embodiment, both the monitor-side 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. Passing a tie through both the third connector tie-down portion 918 and the monitor-side tie-down portion 919 can prevent accidental disconnection of the connector from the monitor. In another embodiment, passing a label through either or both of the third connector tie-down portion 918 and the monitor-side tie-down portion 919 can, for example, in some non-limiting embodiments, provide information about the patient and / or equipment to the user or technician.

[0065] Figure 9s shows a cross-sectional view of the engagement between one of the two controller-side reversible connector portions 941a and / or 941b. One or both of the two controller-side reversible connector portions 941a and / or 941b may alternatively be referred to as female connectors throughout this disclosure. As described above, one or both of the controller-side reversible connector portions are the first connector portion 108a or 108b or the second connector portion 110a or 110b in Figure 1, the first connector portion 308 or the second connector portion 310 in Figures 3a-3c, the first connector portion 408 or the second connector portion 310 in Figures 4a-4b, the first connector portion 508 or the second connector portion 510 in Figures 5a-6, the first connector portion 708 or the second connector portion 710 in Figures 7a-7b, and / or Figure 8 The configuration may be similar to either one of the first connector portion 808 or the second connector portion 810 in Figures a-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 pipe of a certain length. As shown in Figure 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 an interlocking fit type interface. For example, the outer concentric wall 906c of the third connector portion 908 may engage slidingly or frictionally 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 embodiments described above can be reversed without departing from the scope of the present disclosure (for example, 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). 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 above example, the outer concentric wall 906c of the third connector portion 912 may have one or more internal dimensions that are substantially the same as or slightly smaller than the outer concentric wall 906d of the controller-side reversible connection portion 941. As a result, when the two connectors are connected by the user, the outer concentric wall 906c of the third connector portion 912 frictionally engages with the outer concentric wall 906d of the reversible connection portion 941 on the monitor side, forming a seal between them that does not allow fluid loss at the interface or allows only minimal fluid loss. Similarly, the intermediate concentric wall 904c of the third connector portion 912 may slide or frictionally engage with the outer surface of the intermediate concentric wall 904d of the reversible connection portion 941 on the monitor side. The inner concentric wall 914c of the third connector portion 912 may also slide or frictionally engage with the outer surface of the inner concentric wall 914d of the reversible connection portion 941 on the monitor side when the third connector portion 912 is engaged with the reversible connection portion 914 on the monitor side in the first engagement configuration.

[0066] Referring next to Figures 10a and 10b, one exemplary rear or rear side view of the sealing member 1009 is shown. The sealing member 1009 may be similar to the sealing member 909a shown in Figures 9b, 9e, 9g, 9m-9p, and / or the sealing member 909c shown in Figures 9a, 9d, and 9j-9l. For example, in addition to the aforementioned mechanisms of the sealing members 909a and / or 909c, the sealing member 1009 may include a rear engaging portion 1054 with a rear engaging portion outer seal 1056, a first alignment horn 1055a, and a second alignment horn 1055b. The rear engaging portion 1054 on the rear or rear side of the sealing member 1009 may be configured to connect at an interface with the 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 Figure 1, the first connector portion 308 and the second connector portion 310 shown in Figures 3A to 3C, the first connector portion 408 and the second connector portion 410 shown in Figures 4A to 4B, the first connector portion 508 and the second connector portion 510 shown in Figures 5A to 5C, the first connector portion 708 and the second connector portion 710 in Figures 7A to 7B, and / or the first connector portion 808 and the second connector portion 810 in Figures 8A to 8D. In addition, the connector portion 1008 may be similar to, for example, the sleeve-side connection portion 110a in Figure 1. The connector portion interface 1064 may include an outer sealing receiving portion 1066, a first horn receiving portion 1065a, and a second horn receiving portion 1065b. This allows the connector portion interface 1064 of the connector portion 1008 to be configured to engage with the rear engaging portion 1054 of the sealing member 1009. For example, the outer seal 1056 of the rear engaging portion 1054 may be a protruding section of the sealing member 1009 configured to be received by the outer sealing receiving portion 1066 of the connector portion interface 1064. Similarly, the second horn receiving portion or the first horn receiving portion 1065a may be configured to engage with or otherwise receive the first aligned horn 1055a, and the second horn receiving portion 1065b may be configured to engage with or otherwise receive the second aligned horn 1055b. It can be configured to accept this. The aforementioned structure ensures that the sealing member 1009 is installed in the appropriate orientation during the manufacture and / or modification of the reversible connector.

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

[0068] Figure 11a shows a cross-section of the piping 1113 of Figure 11a, which may be used between a controller-controlled fluid source and a compression garment according to an aspect of the present disclosure. The piping outline of piping 1113 may be implemented to create a fluid path between each of the connectors and / or sleeves (e.g., sleeve 100 in Figure 1) and / or controllers (e.g., controller 102 in Figure 1 and / or controller 902 in Figures 9q to 9s). For example, piping 1113 may be used as controller piping 112a and compression garment piping 112b shown in Figure 1. Piping 1113 may also be similar to piping 913 in Figures 9a and 9r. The piping 1113 may include three separate tubes or piping passages or conduits 1123a, 1123b, and 1123c, which correspond to the controller (e.g., controller 102 in Figure 1 and / or controller 902 in Figures 9q to 9s) and the three bladders 106a, 106b, and 106c of the compression garment 104 (Figure 1), and may create fluid pathways between the three bladders 106a, 106b, and 106c. While three tubes or piping passages or conduits 1123a, 1123b, and 1123c are shown in examples and three bladders are provided, aspects of the present disclosure may include more or fewer passages corresponding to the number of inflatable bladders. For example, the piping may include two passages providing fluid communication to two bladders, or four or more passages providing fluid communication to a corresponding number of bladders. For example, in one exemplary implementation, the piping may include four to six passages. In some embodiments, the piping 212 may be similar to the piping described above with respect to Figure 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 piping 1113 is installed in the correct orientation (e.g., not "inverted") with respect to either the connectors 1110 and 1112.In one exemplary implementation of the alignment section 1121, the first connector 1110 and the second connector 1112 may have a first connector alignment section 1114 and a second connector alignment section 1115, respectively, configured to receive the alignment portion 1121 of the piping 1113. In addition to the aforementioned advantages, the aforementioned piping shape also provides a symmetrical appearance at the interface between the piping 1113 and the first connector portion 1110 and / or the second connector portion 1112, thereby providing a symmetrical appearance for the piping and / or connector connected thereto. It can improve the aesthetic appearance of the product.

[0069] Figures 12a and 12b show an embodiment of a locking mechanism with visual indicators to confirm that two or more of the aforementioned reversible connector portions are properly connected. A first connector portion 1208 and a second connector portion 1210 are shown. 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 Figure 1, the first connector portion 308 and the second connector portion 310 shown in Figures 3A to 3C, the first connector portion 408 and the second connector portion 410 shown in Figures 4A to 4B, the first connector portion 508 and the second connector portion 510 shown in Figures 5A to 5C, the first connector portion 708 and the second connector portion 710 in Figures 7A to 7B, and / or the first connector portion 808 and the second connector portion 810 in Figures 8A to 8D. In addition, the first connector portion 1208 may be similar to, for example, the sleeve-side connection portion 110a in Figure 1. Furthermore, the second connector portion 1210 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 1210 may also be similar to the third connector portion 912 in Figures 9a, 9d, 9j, 9k, and 9I, and may be connectable to a controller (e.g., controller 102 in Figure 1 and / or controller 902 in Figures 9q to 9s) and / or may be configured to connect to a controller-side reversible connector portion (e.g., controller-side reversible first connection portion 108a in Figure 1 and / or controller-side reversible connection portions 941a and / or 941b in Figures 9q to 9s). The first connector portion 1208 and / or the second connector portion 1210 may also be similar to the connector portion 1008 in Figure 10b and the connector portions 1112 and / or 1110 in Figure 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 an elastic or semi-elastic connecting portion 1247. Either or both of the pressing portion 1244 and / or the locking portion 1245 can be biased to move so as to engage with or disengage from the locking portion of the second connector 1210 by pressing the pressing portion 1244, or can otherwise be tensioned. 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 flex when the 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 can, for example, lock the first connector portion 1208 in place once the first connector portion 1208 and the second connector portion 1210 are connected and sealed together. The first connector portion 1208 and the second connector portion 1210 can be locked together when the user pushes the first connector 1208 into the second connector 1210 until the locking portion 1245 is securely received within one or more openings 1243. If the user wishes to remove the first connector portion 1208 from the second connector portion 1210, applying pressure to the pressing portion 1244 moves the locking portion 1245 downward, releasing the locking engagement with one or more openings 1243, thereby allowing the user to separate the first connector portion 1208 from the second connector portion 1210. Any one of the locking mechanisms described above may include a visual, tactile, and / or auditory indicator to show the user that the connector is properly connected. For example, as shown in Figure 12b, the locking portion 1245 of the first connector portion 1208 may include a visual indicator, for example, as a colored, brightly colored, or contrastingly colored mechanism to provide visual confirmation that the locking portion 1245 of the first connector is fully engaged and securely received within the opening 1243 of the second connector portion 1210.As a result, the aforementioned visual indicator indicates that the first connector 1208 is properly connected to the second connector 1210, and. This may provide the user with confirmation that a fluid seal has been established between the two connectors. In addition, by pushing the first connector portion 1208 into the second connector, the locking portion 1245 is pushed downward, thereby applying tension to the elastic or semi-elastic connecting portion 1247 until the locking portion 1245 aligns with the opening 1243. Once the locking portion 1245 is aligned with the opening 1243, the locking portion 1245 may spring up into a relaxed state, thereby providing a “snap” or similar tactile or audible indicator that the first connector 1208 is properly connected to the second connector 1210 and that a fluid seal has been established between the two connectors. While a locking mechanism is preferred, those skilled in the art will understand that embodiments of this disclosure still offer advantages to connectors including a single locking mechanism or no locking mechanism at all.

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

[0072] In one embodiment, if a connecting portion, such as a third connector portion 1312, is intended to connect to a surface-mount or rigid connector (e.g., the controller-side reversible connecting portions 941a and / or 941b in Figures 9q-9s), the third connector portion 1312 may include both a top first mechanism 1345a and a bottom first mechanism 1345b so that the user can easily install the third connector portion in either orientation. In some embodiments, such as the first connecting portion 1308 shown in Figure 13a, the connecting portion may be intended to connect to a non-fixed or surface-mount connector (e.g., the sleeve-side reversible connector portion 110a in Figure 1) connected to additional piping. In such cases, it may be necessary to include only a first, i.e., top locking mechanism 1345 on the connecting portion, since the two connecting portions to be connected can be easily reversed or otherwise aligned before connection.

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

[0074] The strain relief section 1446 may include, for example, an annular rounded section configured to control movement and prevent twisting or other potentially damaging bending of the piping 1413. In one embodiment, the strain relief section 1446 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 (acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon), and high-density polyethylene. Any one or the same of the following: HDPE, liquid crystal polymer (LCP), low-density polyethylene (LLDPE), linear low-density polyethylene (LLDPE), ultra-high-molecular-weight polyethylene (UHMW), or similar materials. The combination can be molded, additively manufactured, and / or machined. 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 from a low-durometer material. For example, the strain relief portion 1446 may be any one of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic vulcanized material (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam and / or open-cell PE foam, or any combination thereof.

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

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

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

[0078] Referring next to Figures 15a and 15b, the second connector portion 1510 may include the second connector outer housing 1515b, an outer concentric wall 1506b, an intermediate concentric wall 1504b, and an inner concentric wall 1514b. The inner concentric wall 1514b may be positioned within the intermediate concentric wall 1504b, and the intermediate concentric wall 1504b may be positioned within the outer concentric wall 1506b of the second connector portion 1510. In one exemplary implementation, the second connector outer housing 1515b, the outer concentric wall 1506b, the intermediate concentric wall 1504b, and the inner concentric wall 1514b may be formed as a single integrated component. In one embodiment, the second connector outer housing 1515b, the outer concentric wall 1506b, the intermediate concentric wall 1504b, and the inner concentric wall 1514b may be formed from, for example, a rigid or semi-rigid material. For example, the second connector outer housing 1515b, outer concentric wall 1506b, intermediate concentric wall 1504b, and inner concentric wall 1514b are made of acrylonitrile butadiene styrene (ABS), polycarbonate (PC), and poly 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 (acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon), and any one or a combination thereof from 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.

[0079] Next, with reference to Figure 15c, embodiments of the fluid path are described below. The first connector portion 1508 may have a pipe connection section 1585a, and the second connector portion 1510 may have a pipe connection section 1585b. The first connector portion 1608 may have a pipe connection portion 1685 that can be detachably or permanently connected to, for example, pipes 112b, 112c and / or 112a in Figure 1, pipes 212 or 213 in Figures 2a and 2b, pipes 422a to 422c in Figures 4a to 4b, pipes 722a to 722c in Figures 7a to 7b, and pipes 913 and / or 942 in Figures 9a and 9r. In some embodiments, the outer concentric wall 1506a, intermediate concentric wall 1504a, and inner concentric wall 1514a of the first connector portion 1508 may be adapted (i.e., sized) to engage with the outer concentric wall 1506b, intermediate concentric wall 1504b, and inner concentric wall 1514b of the second connector portion 1510 shown in Figure 15c to form a reversible connector 1520 in an engaging configuration. The above configurations allow the first connector portion 1508 and the second connector portion 1510 to be connected in a first configuration (e.g., as shown in Figure 15c) to follow the first fluid flow channel in the connector, or in a second engaging configuration (e.g., a “reversed” configuration) to follow the second fluid flow channel, without changing the order of the fluid communication paths of three separate fluid paths (e.g., paths 1, 2, and 3). When the connection is "reversed" (for example, when either the first connector 1508 or the second connector 1510 is inverted by 180 degrees), the 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] As shown in Figures 15a and 15b, the first connector portion 1508 and the second connector portion 1510 may have a first connector engagement portion 1516a and a second connector engagement portion 1516b, respectively. The first connector engagement portion 1516a may be configured to fit into the second connector engagement portion 1516b. The engagement between the first connector engagement portion 1516a and the second connector engagement portion 1516b may function, for example, as a guide for connecting the first connector portion 1508 to the second connector portion 1510.

[0081] In one embodiment, the first connector portion 1908 may have one or more locking mechanisms 1541a (one locking mechanism 1541a is hidden in Figure 15a) configured to lockingly engage with one or more locking mechanisms 1541b of the second connector portion. In one embodiment, one or more locking mechanisms 1541b of the second connector portion may be openings sized to receive each of the locking mechanisms 1541a of the first connector portion 1508. In one aspect, the locking mechanisms 1541a and 1541b of the first connecting portion and the second connector portion may include the mechanisms described in Figures 12a to 13b above. In the shown embodiment, the locking mechanism of the first connector 1541a includes at least one pressing portion. The pressing portion of the locking mechanism 1541a of the first connector 1508 may be biased or otherwise tensioned so that pressing the pressing portion causes the locking portion 1541a to move and engage or disengage with the locking portion 1541b of the second connector 1510. In one embodiment, the first The pressing or locking portion 1541a 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 flex when the user presses the locking portion. The second connector locking mechanism may include, for example, one or more openings 1541b configured to lockingly receive the locking portion 1541a of the first connector portion 1508. If the user wishes to remove the first connector portion 1508 from the second connector portion 1910, applying pressure to the pressing portion of the locking portion 1541a moves the locking portion 1541a downward, releasing the locking engagement with one or more openings of the locking portion 1541b 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 auditory indicator to show the user that the connector is properly connected. One embodiment of a visual indicator is described further with respect to Figures 12a and 12b above.

Additionally, the second connector portion 1610 may be similar to, or include, the mechanism of the first reversible connector portion 108b in Figure 1, or similar to, or include the mechanism of the second reversible connector portion 110b. The first reversible connector portion 1608 may also be similar to, or include, the mechanism of the third connector portion 912 in Figures 9a, 9d, 9j, 9k, and 9l, and may be portion 1585a (reversible connector portions 941a and / or 941b on the controller side in Figures 108a and / or 9q to 9s). The first connector portion 1608 and / or the second connector portion 1610 may also be similar to, or include, the mechanisms of, the connector portion 1008 in Figure 10b, 1112 and / or 1110 in Figure 11a, 1208 or 1210 in Figures 12a and 12b, 1308 and 1312 in Figures 13a and 13b, 1408 and 1412 in Figures 14a and 14b, and 1508 or 1510 in Figures 15a to 15c. The first connector portion 1608 may have a pipe connection portion 1685a, and the second connector portion may have a pipe connection portion 1685b.The wiring connection portions 1685a and / or 1685b may be detachably or permanently connected to, for example, the wiring 112b, 112c, and / or 112a in Figure 1, the piping 212 or 213 in Figures 2a and 2b, the piping 422a to 422c in Figures 4a to 4b, the piping 722a to 722c in Figures 7a to 7b, and the piping 913 and / or 942 in Figures 9a and 9r. The first connector portion 1608 may include, for example, the main body portion 1615a. The first connector portion 1608 may further include a first sealing portion 1642a, a second sealing portion 1642b, and / or a third sealing portion 1642c. Each of the first sealing portion 1642a, the second sealing portion 1642b, and / or the third sealing portion 1642c may consist of, for example, a seal (e.g., an O-ring or other flexible seal) housed within each 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 connected to the second connector When engaged with the connector portion 1610, the 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 connector 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 a fluid, such as air, to pass from the first connector portion 1608 to the second connector portion 1610. The first and second connectors may additionally include third openings 1646a and 1647a, respectively, which provide direct fluid communication when the first connector portion 1608 is connected to the second connector portion 1610. The aforementioned mechanism enables the first and second connectors to provide fluid communication along their respective paths 1, 2, and 3, regardless of the orientation of the first connector portion 1608, when they engage and connect to the second connector portion 1610. For example, as shown in Figure 16d, fluid communication between the first chamber 1604, the second chamber 1602, and the third opening 1646a of the first connecting portion 1608 and the third opening 1647a of the second connector portion 1610 provides fluid communication paths (1), (2), and (3) from the first connector portion 1608 to the second connector portion 1610, regardless of whether they are connected in a first orientation (e.g., as shown in Figures 16c and / or 16d) or whether they are inverted 180 degrees and connected in a second orientation.

The irreversible connection portion 1705 may include any known connector that is connectable to a second corresponding connector but must normally be connected to a connector corresponding to a single orientation (e.g., cannot be "reversed" 180 degrees). The aforementioned embodiments offer the advantage that the systems, methods, and apparatus of the present disclosure can be used with commercially available products (e.g., compression garments, pipe extensions, and / or controllers) or products that include irreversible connectors or connectors having different connection interfaces. In one embodiment, the reversible connection portions 1708 / 1712 of the adapter 1719 may be male connectors.

In one exemplary implementation, the adapter 1819 may be configured to connect or adapt, for example, a controller utilizing an irreversible connector (e.g., controller 102 in Figure 1 and / or controller 902 in Figures 9q to 9s) to a system of the present disclosure that utilizes one or more reversible connectors. The adapter 1819 may have an irreversible connection portion 1806 at a first end and a reversible connection portion 1810 / 1841 at a second end. The adapter 1819 may also include piping 1813 for providing fluid communication between the fluid passages in the irreversible connection portion 1806 and / or the reversible connection portion 1810 / 1841. While not limited to specific pipe outlines, in preferred embodiments the pipe may include any one of the pipe outlines shown in Figures 2a to 2c above. The irreversible connection portion 1806 may include any known connector that is connectable to a second corresponding connector but must normally be connected to a connector corresponding to a single orientation (for example, one that cannot be "reversed" 180 degrees when connected to a corresponding connector). The aforementioned embodiments offer the advantage that the systems, methods, and apparatus of the present disclosure can be used with commercially available products (e.g., compression garments, pipe extensions, and / or controllers) or products that include irreversible connectors or connectors having different connection interfaces. In one embodiment, the reversible connection portions 1810 / 1841 of the adapter 1819 may be female connectors.Furthermore, the reversible connection portion 1810 / 1841 may be similar to, or include, the mechanisms of, the first connector portion 108a on the controller side and the reversible second connector portion 110a on the sleeve side 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.

The reversible connection portion 1810 / 1841 also includes connector portion 1008 in Figure 10b, 1112 and / or 1110 in Figure 11a, 1208 or 1210 in Figures 12a and 12b, and 1308 in Figures 13a and 13b. , 1312, 1408 and 1412 in Figures 14a and 14b, and 1508 or 1510 in Figures 15a to 15c may be similar to or include such mechanisms. Reversible connection parts 1810 / 1841 and / or irreversible connection parts 1806 may have pipe connection parts (for example, as described and shown in reference to reference no. 1685a and 1685b in Figures 16a and 16b).

[0087] Figures 19a–19c are pressure charts showing the pressure in each bladder of a compression garment (e.g., bladder 106a, 106b, and 106c in Figure 1) provided through a reversible connector over time while the controller (e.g., controller 102 in Figure 1 or controller 902 in Figures 9q–9s) is operating. The fluid passages within the connector described throughout this disclosure provide consistent performance when the connector is connected in a first configuration 1900a and / or a second configuration 1900b (e.g., when one of the two connectors or connector portions is reversed 180 degrees). For example, the fluid pressure chart in Figure 19b shows the fluid pressures 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 a first orientation. The fluid pressure chart in Figure 19c shows the fluid pressures supplied through the first fluid path (1), the second fluid path (2), and the third fluid path (3) when the first connector portion 1808 is connected to the second connector portion 1910 in a second orientation (e.g., "reversed" or 180-degree orientation from the first orientation shown in Figure 19c). As shown, switching either the first connector 1908 and / or the second connector portion 1910 from the first orientation to the second orientation has only a minimal effect on the pressure supplied 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-side connector portion 944 described above with respect to Figures 9a to 9s.In another embodiment, the first connector portion 1708 and the second connector portion may be similar to, or include, the mechanisms of, 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 to 3C, the first connector portion 408 and the second connector portion 410 shown in Figures 4A to 4B, the first connector portion 508 and the second connector portion 510 shown in Figures 5A to 5C, the first connector portion 708 and the second connector portion 710 in Figures 7A to 7B, and / or the first connector portion 808 and the second connector portion 810 in Figures 8A to 8D.
