Description

[0001] Cross-references to related applications

[0002] This application claims priority to U.S. Provisional Application No. 63 / 028,819, filed May 22, 2020, entitled “SYSTEM, METHOD, AND DEVICEUTILIZING REVERSIBLE CONNECTOR”, the entire disclosure of which is incorporated herein by reference. Technical Field

[0003] This disclosure relates to a system, method, and apparatus for inflating a pressure garment from a fluid source connected via a reversible connector, wherein the reversible connector provides unidirectional fluid flow through a plurality of fluid grooves when connected in a first or second orientation. Background Technology

[0004] The vascular compression system includes a compression garment fluidly connected to a fluid source for circulatory inflation of the garment when it is worn on a patient's limb. Circulatory inflation of the compression garment enhances blood circulation and reduces the likelihood of deep vein thrombosis (DVT). A controller regulates the operation of the fluid source to deliver fluid (e.g., air) to the bladder of the compression garment, thereby creating a pressure gradient along the garment that directs blood flow in a desired direction.

[0005] In conventional vascular compression systems, a controller supplies fluid (e.g., air) to the compression garment via tubing, which may include, for example, three separate fittings. Typically, a connector connects the tubing extending from the controller (i.e., the controller tubing) and the tubing extending from the compression garment (i.e., the garment tubing). The garment tubing supplies fluid to multiple sacs (e.g., two, three, four, or more) of the compression garment. For example, in the case of three sacs, the three sacs may include a distal sac positioned around the wearer's ankle, a middle sac positioned around the wearer's calf, and a proximal sac positioned around the wearer's thigh. Because the three fittings in the tubing are very close together, the connector must be appropriately sized to allow fluid (e.g., air) and restrict the separation of the three fittings. Typically, the three fittings of the tubing are connected side-by-side. Conventional connectors used to connect the controller tubing and the garment tubing can only connect in a single orientation. In some implementations, the connector cannot connect in more than one orientation, or when connected in a second orientation, it cannot provide fluid connection to all three fittings, which may lead to malfunction of the compression system and / or potentially cause injury or discomfort to the patient. Therefore, there is a need in the art for a connector for connecting all fittings (e.g., two, three, four or more) of the controller tubing and garment tubing in more than one orientation (e.g., straight and reverse orientations) while providing fluid flow in a single direction from the fluid source of the controller to the pressurized garment, regardless of the connection orientation, thereby ensuring proper functioning of the pressurization system and avoiding the possibility of discomfort or injury to the patient. Summary of the Invention

[0006] This disclosure includes a pressure garment capable of being selectively engaged and operated by a controller via a reversible connector for inflation. The pressure garment includes a plurality of bladders and a pressure garment conduit, the conduit including a plurality of garment fittings in fluid communication with the plurality of bladders at a first end of the pressure garment conduit. A second end of the pressure garment conduit is disposed opposite to the first end of the pressure garment conduit, and a first connector portion is located at the second end of the pressure garment conduit. The controller controls communication with a fluid flow source and includes a controller conduit having a plurality of controller fittings selectively in communication with the fluid flow source at the first end of the controller conduit. The controller conduit also includes a second end of the controller conduit opposite to the first end of the controller conduit and a second connector portion located at the second end of the controller conduit. The first connector portion of the garment conduit and the second connector portion of the controller conduit are selectively and reversibly connected together 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 groove when the first connector portion is engaged to the second connector portion in a first orientation. When the first connector portion is connected to the second connector portion in a second orientation, the plurality of fluid flow passages within the first connector portion and the plurality of fluid flow passages within the second connector portion cooperate to form a second fluid flow groove. When the first connector portion and the second connector portion are connected in a first orientation, the fluid flow between the first controller tube among the plurality of controller tubes and the first pressure garment tube among the plurality of pressure garment tubes is transmitted via the first fluid flow groove in the first fluid flow direction. When the first connector portion and the second connector portion are connected in a second orientation, the fluid flow through the first pressure garment tube among the plurality of pressure garment tubes and the first controller tube among the plurality of controller tubes is transmitted via the second fluid flow groove in the first fluid flow direction.

Detailed Implementation

[0070] The various aspects will now be described in more detail with reference to the accompanying drawings. In the following description, numerous specific details are set forth for illustrative purposes in order to provide a thorough understanding of one or more aspects. However, it will be apparent, however, that these aspects can be practiced without these specific details. Furthermore, as used herein, the term "component" can refer to one of the parts that make up a system, and can be hardware, firmware, and / or software stored on a computer-readable medium, and can be divided into other components.

[0071] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this disclosure. Various procedures or components may be appropriately omitted, substituted, or added to the various examples. For example, the described methods may be performed in a different order than described, and various steps may be added, omitted, or combined. Furthermore, features described with respect to some examples may be combined in other examples.

[0072] The term "reversible" is used throughout the disclosure as a modifier for a connector or a series of connectors. In context, examples of the term "reversible connector" include a connector or a set of connectors that can be connected in at least two different orientations (e.g., "flipped" or rotated 180 degrees about an axis) without affecting the order in which the bladder in a pressurized garment inflates. This example contrasts with an irreversible connector, in which reversing the connection orientation (e.g., rotating the connector 180 degrees about an axis) affects the order in which the bladder inflates in the pressurized garment inflates.

[0073] Turn to the accompanying drawings, where the same reference numerals refer to the same components. Figure 1 An exemplary pressurization system 100 is illustrated, and various features of this pressurization system are available for use according to aspects of this disclosure. The pressurization system 100 includes a controller 102, a pressurization garment 104, and one or more reversible connectors 120. (As...) Figure 1 As shown, the pressure garment 104 can be connected to the controller 102 by directly connecting the sleeve-side reversible second connector portion 110a to the controller-side reversible first connector portion 108a, or by connecting the two aforementioned connector portions with an extension or adapter 119. The extension or adapter 119 can provide additional distance between the controller 102 and the pressure garment 104 and / or adapt different connectors (e.g., different engagement features with fluid channel configurations) to one or both of the controller 102 and / or the pressure garment 104. Throughout this disclosure, the terms adapter and extension are used interchangeably. In one example, the extension 119 may, for example, include a first reversible connector portion 108b at one end and a second reversible connector portion 110b at a second end, wherein a connecting conduit 112c provides a fluid connection between the two connector portions. The first reversible connector portion 108b and the second reversible connector portion 110b may, for example, resemble the controller-side reversible first connector portion 108a and the sleeve-side reversible second connector portion 110a, respectively. Furthermore, while specific examples of connectors for the pressure garment 104, controller 102, and / or adapter 119 are shown, those skilled in the art will understand that any connector portion or connection feature described throughout the specification can be used in any known method or configuration for connecting the controller 102 to the pressure garment 104. Additionally, any or a combination 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 are interchangeably referred to as the first connector portion or the second connector portion throughout the disclosure.

[0074] Figure 1An example is shown of a first connector portion 108 and a second connector portion 110 in an unconnected configuration, along with a pressure garment 104. The pressure garment 104 is configured to apply sequential pressure therapy to the limbs of a wearer (e.g., a medical patient requiring pressure therapy), and a controller 102 having one or more processors and / or pumps or fluid sources and configured to control the operation of the pressure garment 104. The pressure garment 104 may include multiple sacs capable of containing fluids such as air. For example, the pressure garment 104 may include a distal inflatable sac 106a, a middle inflatable sac 106b, and a proximal inflatable sac 106c. Although reference is made herein to three bladders, it will be apparent that fewer or more bladders, such as one, two, or four, may be used, and as will be described in more detail below, the reversible connector 120 according to various aspects of this disclosure is configured to operatively engage and connect the pressure garment 104 to the controller 102, regardless of whether the pressure garment comprises only one inflatable bladder 106a, 106b, 106c or more than one inflatable bladder 106a, 106b, 106c. The pressure garment 104 may be secured around the wearer's limb (e.g., using hook-and-loop fasteners or straps, and other types of securing mechanisms) and may be adjustable to fit around limbs of different sizes / circumferences.

[0075] In some aspects, controller 102 may include a pump or other fluid source and control the operation of pressure garment 104 to perform a pressure cycle in which inflatable bladders 106a, 106b, 106c inflate to apply pressure to the wearer's limb, thereby establishing a pressure gradient applied to the limb by controlling the fluid within the inflatable bladders 106a, 106b, 106c of pressure garment 104 during one or more pressure cycles. For the purpose of describing exemplary operation of pressure system 100, each pressure cycle may be followed by a deflation cycle in which the pressure in each of the inflatable bladders 106a, 106b, 106c is released. The pressure cycle and the deflation cycle together form a complete treatment cycle of pressure system 100. Pressure system 100 may measure the pressure gradient applied by inflatable bladders 106a, 106b, 106c and may be adjusted based on the measured pressure gradient. In some respects, during operation of the pressurization system 100, the pressurization system 100 may not measure the pressure gradient and / or may not adjust the pressure gradient based on the measurement results. Instead, the pressurization system 100 may inflate and / or deflate the bladder of the pressurized garment 104.

[0076] The pressure garment 104 may be a thigh-length sleeve capable of being positioned around the wearer's legs, a distal inflatable bladder 106a capable of being positioned around the wearer's ankle, a middle inflatable bladder 106b capable of being positioned around the wearer's calf, and a proximal inflatable bladder 106c capable of being positioned around the wearer's thigh. The inflatable bladders 106a, 106b, and 106c can expand and contract under the action of a fluid (e.g., air or other fluid) delivered from a pressure fluid source via a controller 102. The controller 102 can deliver pressure fluid from the fluid source to the inflatable bladders 106a, 106b, and 106c. The pressure fluid source can deliver pressure fluid to the inflatable bladders 106a, 106b, and 106c via a reversible first connector portion 108a on the controller side, which can be connected to the controller 102 via a controller conduit 112a and / or form the controller body (e.g., as shown in the image). Figures 9q to 9s (As shown), a portion of the reversible connector 120 and the pressurized garment conduit 112b. As explained in further 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 pressurized garment side, and / or may include an adapter 119 having a first reversible connector portion 108b, a second reversible connector portion 110b, and a connecting conduit 112c. The first connector portion 108a may be coupled to one end of the controller conduit 112a (the other end of which is coupled to the controller 102), and the second connector portion 110a may be coupled to one end of the pressurized garment conduit 112b (the other end of which is coupled to the pressurized garment 104). Although Figure 1 Only a single first connector portion 108 and second connector portion 110 are shown, but aspects of this disclosure can be applied to extension fitting assemblies (e.g., a section of pipe having a connector at either end) and / or adapters (e.g., a section of pipe having a first-type connector at one end and a second-type connector at the other end). Reference is made below. Figure 17 and Figure 18 Describe some non-limiting examples of adapters. Furthermore, although in Figure 1 While the connectors are hidden, any one or combination of the connectors described herein can be used to provide a controller-side connection between controller 102 and any one or combination of the adapter, extension fitting assembly, and / or pressure garment 104. See below for reference. Figures 9q to 9s Some examples of controller-side connectors are described in more detail.

[0077] Figure 2a An exemplary section of conduit 212, according to aspects of this disclosure, can be utilized between a fluid source controlled by a controller and a pressurized sleeve. Conduit 212 may be similar to... Figure 1The controller conduit 112a and pressurized garment conduit 112b shown are in an unconnected configuration and may include three separate fittings or conduits 222a, 222b, 222c (such fittings, conduits, or pipes are interchangeably referred to herein as "fittings") for use with Figure 1 The pressure garment 104 shown has individual fittings for each of the inflatable bladders 106a, 106b, 106c. In some aspects, the conduit 212 may be a smooth conduit having, for example, three individual fittings 222a, 222b, 222c housed within a single conduit 212. In other aspects, the conduit 212 may include three individual fittings 222a, 222b, and 222c, each formed as a separate piece. The conduit 212 may be flexible. The conduit 212 may be made of polyvinyl chloride (PVC), polyurethane, or any suitable material to deliver fluid to the pressure garment 104, such as... Figure 1 As shown. As will be described in more detail below, the reversible connector 120 according to various aspects of this disclosure is configured to operatively engage and connect the pressure garment 104 to the controller 102, regardless of whether the conduit 212 includes, as Figure 2a The three individual fittings 222a, 222b, 222c shown, or more / fewer individual fittings 222a, 222b, 222c, such as a single fitting (not shown), two fittings (not shown), or more than three fittings (not shown).

[0078] Figure 2b A cross-section of another exemplary embodiment of a conduit 213 that can be used between a fluid source controlled by a controller and a pressurized garment, according to aspects of this disclosure, is shown. Figure 2a and / or Figure 2b Any or any combination of the pipe profiles shown can be implemented in connectors and / or sleeves (e.g., Figure 1 (in the bushing 100) and / or controller (e.g., Figure 1 A fluid path is created between each of the controllers (102) in the system. For example, pipe 212 can be used as... Figure 1 The controller conduit 112a and the pressure garment conduit 112b are shown. Conduit 213 can be flexible. Conduit 213 can be made of polyvinyl chloride (PVC), polyurethane, or any suitable material to deliver fluid to the pressure garment 104, such as... Figure 1 As shown. In a preferred aspect, the material of pipe 213 may be flexible or semi-flexible while maintaining sufficient rigidity to prevent kinking or shrinkage of the fitting (and thus obstruction of fluid flow). Pipe 213 may include three separate fittings or pipe channels or conduits 223a, 223b, 223c, which may correspond to a controller (e.g., Figure 1 The controller 102 and the three bladders 106a, 106b, and 106c of the pressure garment 104 create a fluid path between the controller and the three bladders. While three tubing or conduit channels or conduits 223a, 223b, and 223c are shown, and three bladders are provided as an example, aspects of this disclosure may include more or fewer channels corresponding to the number of inflatable bladders. For example, a conduit may include two channels providing fluid communication with two bladders, or it may include more than three channels providing fluid communication with a corresponding number of bladders. For example, in one exemplary embodiment, a conduit may include four to six channels. In one variation, having as... Figure 2b The conduit 213, as outlined, can create a fluid path between any of the following or combinations thereof: for example, through the connector, pressure garment 104, and / or controller 102 described in this disclosure. In some aspects, conduit 212 may be similar to the above description. Figure 2a The described conduit may also include an additional alignment section 221. The alignment section may, for example, include an additional channel or alignment feature comprising a first alignment portion 224 and a second alignment portion 225. One function of the alignment section 221 may be to ensure that the conduit 213 is installed in the correct orientation relative to any of the connectors described in this disclosure (e.g., not "flipped"). Reference below... Figure 10a , Figure 10b , Figure 11a and Figure 11b An exemplary implementation of alignment section 221 and the interaction between alignment section 221 and corresponding portions of the connector (e.g., during pipe and connector assembly) are described.

[0079] Figure 3a An exemplary reversible connector 320 according to aspects of this disclosure is shown, the reversible connector having a first connector portion 308 and a second connector portion 310 (also interchangeably referred to herein as a "connector assembly" or "connector portion") in a connection configuration (such connection configuration may also be referred to herein as a "joint" or "coupling" configuration). The first connector portion 308 and the second connector portion 310 may be similar to Figure 1 The first connector portion 108 and the second connector portion 110 are shown. It should be understood that the first connector portion 308 and the second connector portion 310 can be connected via different types of engagement features, including features for providing sliding engagement, compression engagement, snap-fit ​​engagement, magnetic engagement, and other types of engagement. Reference is made below. Figures 5a to 9s , Figures 12a to 13b and Figures 15a to 15b Another example describing the joining features.

[0080] like Figure 3b As shown, the first connector portion 308 may include an outer concentric wall 306a, a middle concentric wall 304a, and an inner concentric wall 314a. The inner concentric wall 314a may be positioned within the middle concentric wall 304a, and the middle concentric wall 304a may be positioned within the outer concentric wall 306a in the first connector portion 308.

[0081] Now for reference Figure 3c The second connector portion 310 may include an outer concentric wall 306b, a middle concentric wall 304b, and an inner concentric wall 314b. The inner concentric wall 314b may be positioned within the middle concentric wall 304b, and the middle concentric wall 304b may be positioned within the outer concentric wall 306b of the second connector portion 310.

[0082] In some respects, Figure 3b The outer concentric wall 306a, the middle concentric wall 304a, and the inner concentric wall 314a of the first connector portion 308 shown can be adapted (i.e., their dimensions are set) to be compatible with... Figure 3c The outer concentric wall 306b, the middle concentric wall 304b, and the inner concentric wall 314b of the second connector portion 310 shown are joined to form a reversible connector 320 in a joined configuration, as shown. Figure 3a As shown. For example, when the first connector portion 308 and the second connector portion 310 are engaged to form a reversible connector 320 in an engaged configuration, the outer concentric wall 306a of the first connector portion 308 can engage inside the outer concentric wall 306b of the second connector portion 310, the middle concentric wall 304a of the first connector portion 308 can engage inside the middle concentric wall 304b of the second connector portion 310, and the inner concentric wall 314a of the first connector portion 308 can engage inside the inner concentric wall 314b of the second connector portion 310, as shown. Figure 3c As shown.

[0083] In some aspects, all the concentric walls of the first connector portion 308 can be adapted such that each concentric wall of the first connector portion 308 (i.e., the outer concentric wall 306a, the intermediate concentric wall 304a, and the inner concentric wall 314a) engages with the interior of the corresponding wall of the second connector portion 310 (i.e., the outer concentric wall 306b, the intermediate concentric wall 304b, and the inner concentric wall 314b). In these aspects of the present disclosure, the first connector portion 308 may be a convex connector portion, and the second connector portion 310 may be a concave connector portion.

[0084] In some aspects, one or more of the outer concentric wall 306a, the intermediate concentric wall 304a, and the inner concentric wall 314a of the first connector portion 308, as well as the corresponding concentric walls (i.e., the outer concentric wall 306b, the intermediate concentric wall 304b, and the inner concentric wall 314b of the second connector portion 310), can be adapted such that the outer concentric wall 306a, the intermediate concentric wall 304a, and the inner concentric wall 314a of the first connector portion 308 engage with the corresponding concentric walls of the second connector portion 310, i.e., the outer concentric wall 306b, the intermediate concentric wall 304b, and the inner concentric wall 314b. In these aspects of the present disclosure, a convex connector portion or a concave connector portion may be omitted.

[0085] It should be noted that, although Figure 3a and Figure 3b 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 are shown as rectangles, and the inner concentric walls 314a and 314b of the first connector portion 308 and the second connector portion 310 are shown as circular shapes, but aspects of this disclosure are not limited to such configurations described in more detail herein (e.g., all walls may be rectangular, square, elliptical or circular).

[0086] Refer again Figure 3a and Figure 3b Each of the outer concentric wall 306a, the intermediate concentric wall 304a, and the inner concentric wall 314a of the first connector portion 308 can extend from the base 302a of the first connector portion 308. Each of the outer concentric wall 306b, the intermediate concentric wall 304b, and the inner concentric wall 314b of the second connector portion 310 can extend from the base 302b of the second connector portion 310. The height of the concentric walls (i.e., the extent to which the concentric walls extend away from the bases 302a, 302b) can be appropriately set to form corresponding chambers 402, 404, 406 for each concentric wall when the first connector portion 308 is engaged or connected to the second connector portion 310 (e.g., via slidable engagement, compression fit, snap-fit ​​fit, magnetic engagement, and other types of engagement methods). Figure 4a and Figure 4b (As shown). For example, when the first connector portion 308 and the second connector portion 310 are slidably engaged, the outer concentric wall 306a of the first connector portion 308 and the outer concentric wall 306b of the second connector portion 310 form a chamber 402 (as shown). Figure 4a and Figure 4bAs shown), to allow fluid, such as air, to flow from the first connector portion to the second connector portion. In another example, when the first connector portion 308 is slidably engaged with the second connector portion 310, the 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 (as shown). Figure 4a and Figure 4b As shown), to allow fluid, such as air, to flow from the first connector portion to the second connector portion. In yet another example, when the first connector portion 308 is slidably engaged with the second connector portion 310, the inner concentric walls 314a of the first connector portion 308 and the inner concentric walls 314b of the second connector portion 310 form a chamber 406 (as shown). Figure 4a and 4b As shown), to allow fluid, such as air, to flow from the first connector portion to the second connector portion. The dimensions of the height of the concentric walls can be set such that the formed chambers 402, 404, 406 fluidly communicate the first connector portion 308 and the second connector portion 310, wherein the formed chambers 402, 404, 406 (as shown) allow fluid, such as air, to flow from the first connector portion 308 to the second connector portion 310. Figure 4a and Figure 4b Each chamber in (as shown) provides a seal to prevent little or no fluid leakage, thereby forming interlocking fluid flow connection grooves.

[0087] In some respects, the height of the outer concentric wall 306a of the first connector portion 308 can be variable (i.e., the outer concentric wall 306a can be composed of wall segments of different heights). For example... Figure 3b As shown, for example, the height of the longer side of the outer concentric wall 306a can be less than the height of the shorter side of the outer concentric wall 306a. In some aspects, the height of the longer side of the outer concentric wall 306a can be greater than the height of the shorter side of the outer concentric wall 306a. When the first connector portion 308 engages with the second connector portion 310 to form a reversible connector 320 in an engaged configuration, the height difference between the longer and shorter sides can allow for greater flexibility.

[0088] Refer again Figure 3a and Figure 3bIn the first connector portion 308, fluid flow passage 324a and fluid flow passage 324b can be formed in the intermediate concentric wall 304a, and fluid flow passage 324c can be formed by the inner concentric wall 314a. In the second connector portion 310, fluid flow passage 326a and fluid flow passage 326b can be formed in the intermediate concentric wall 304b, and fluid flow passage can be formed by the inner concentric wall 314b. One or more fluid flow passages formed in the intermediate concentric wall 304a of the first connector portion 308 and / or one or more fluid flow passages formed in the intermediate concentric wall 304b of the second connector portion 310 may include raised blocks 328a, 328b, 330a, 330b to guide or reflect fluid (e.g., air) to corresponding chambers 402, 404 formed by the outer concentric walls 306a, 306b and the intermediate concentric walls 304a, 304b (e.g., air). Figure 4a and Figure 4b As shown in the figure, as described in more detail below.

[0089] Figure 4a and Figure 4b This is a top cross-sectional view of an example of a reversible connector in a first and second orientation, showing the flow of fluid in each orientation. When the first connector portion 408 engages with the second connector portion 410, each of the corresponding concentric walls forms a corresponding chamber 402, 404, 406, which allows fluid, such as air, to flow from the first connector portion 408 to the second connector portion 410. The first connector portion 408 and the second connector portion 410 are similar to... Figure 1 and Figures 3a to 3c The first connector portion 108 and the second connector portion 110, as well as the first connector portion 308 and the second connector portion 310, are shown. For example, the outer concentric wall 406a of the first connector portion 408 can slide into the outer concentric wall 406b of the second connector portion 410 to form an outer chamber 402. In another example, the intermediate concentric wall 404a of the first connector portion 408 can slide into the intermediate concentric wall 404b of the second connector portion 410 to form an intermediate chamber 404. In yet another example, the inner concentric wall 414a of the first connector portion 408 can slide into the inner concentric wall 414b of the second connector portion 310 to form an inner chamber 406. The outer concentric walls 406a and 406b, the intermediate concentric walls 404a and 404b, and the inner concentric walls 414a and 414b of the first connector portion 408 and the second connector portion 410 are similar to... Figure 3b and Figure 3cThe first connector portion 308 and the second connector portion 310 are shown with outer concentric walls 306a and 306b, middle concentric walls 304a and 304b, and inner concentric walls 314a and 314b.

[0090] In reversible connector 420 (similar to) Figure 1 and Figure 3a The first orientation of the reversible connector 120 and reversible connector 320 shown is as follows: Figure 4a As shown, when the first connector portion 408 engages with the second connector portion 410 in the first orientation, the outer chamber 402 can be [transformed / contained / determined]. Figure 3b and Figure 3c The fluid flow passages 324a and 326a shown are substantially aligned with each other, forming an intermediate chamber 404. Figure 3b and Figure 3c The fluid flow passages 324b and 326b shown are substantially aligned with each other, and the inner chamber 406 can be formed by... Figure 3b and Figure 3c The fluid flow passages 324c and 326c shown are substantially aligned with each other and are formed. Figure 3b and Figure 3c As shown, fluid flow passages 324a and 326a can be substantially aligned with adjacent raised blocks 328a and 330a to form an outer chamber 402 (e.g., Figure 4a (as shown), and the fluid flow passages 324b and 326b can be substantially aligned with the adjacent raised blocks 328b and 330b to form the intermediate chamber 404 (as shown). Figure 4a (As shown). Therefore, in the first orientation, the reversible connector 420 is connected from the controller pipe 412a (similar to...). Figure 1 The controller pipe 112a shown has three fittings 422a, 422b, and 422c (which may be similar to...). Figure 2a The pipe fittings 222a, 222b, 222c shown are Figure 2b 223a, 223b, and 223c receive fluid, such as air, and respectively supply fluid to clothing pipe 412b (similar to...). Figure 1The three fittings 422a, 422b, 422c of the pressurized garment conduit 112b shown provide fluid, such as air. The fluid flow from the three fittings 422a, 422b, 422c of the controller conduit 412a to the three corresponding fittings 422a, 422b, 422c of the garment conduit 412b forms fluid connection grooves in the first orientation of the reversible connector 420, as indicated by arrows 430a, 430b, 430c. According to another aspect of the invention, for example, for use on pressurized garments (not shown) having fewer than three inflatable bladders, it may be necessary to have only one or two fittings 422a, 422b, 422c of the garment conduit 412b. Although in Figures 3a to 4b The example shows individual fittings, but in an alternative aspect, fittings 422a, 422b, and 422c can be similar to... Figure 2a The channels 222a, 222b and / or 222c of the pipe 212 and / or Figure 2b Any or a combination of channels 223a, 223b and / or 223c of the conduit 213.

Figure 3b and Figure 3c The fluid flow passages 324a and 326a shown are offset from each other, and the intermediate chamber 404 can be formed by... Figure 3b and Figure 3c The fluid flow passages 324b and 326b shown are offset from each other and are formed, and the inner chamber 406 can be formed by... Figure 3b and Figure 3c The fluid flow paths 324c and 326c shown are offset from each other and are formed. Figure 3b and Figure 3c As shown, fluid flow passages 324a and 326a can be offset from each other, wherein raised blocks 328a and 330a are offset from each other to form an outer chamber 402 (e.g., Figure 4a (as shown), and fluid flow passages 326a, 326b can be offset from each other, wherein raised blocks 328b, 330b are offset from each other to form an intermediate chamber 404 (as shown).

Figure 1 The controller pipe 112a shown has three fittings 422a, 422b, and 422c (which may be similar to...). Figure 2aThe pipe fittings 222a, 222b, 222c shown are Figure 2b 223a, 223b, and 223c receive fluid, such as air, and respectively supply fluid to clothing pipe 412b (similar to...). Figure 1 The three fittings 422c, 422b, 422a of the pressurized garment conduit 112b shown are supplied with fluid, such as air. The fluid flow from the three fittings 422a, 422b, 422c of the controller conduit 412a to the three corresponding fittings 422c, 422b, 422a of the garment conduit 412b forms a fluid connection groove in the second orientation of the reversible connector 420, as indicated by arrows 430, 430b, 430c.

[0092] like Figure 4a and Figure 4b As shown, the first connector portion 408 may include three inlets 416a, 416b, and 416c extending from the base 302a, as... Figure 3b As shown, the second connector portion 410 may include three inlets 416a, 416b, and 416c extending from the base 302b, as... Figure 3c As shown. In the first connector portion 408, three inlets 416a, 416b, and 416c extend from opposite ends of the base 302a, as... Figure 3b As shown, concentric walls 306a, 304a, and 314a extend from the opposite ends. In the second connector portion 410, three inlets 418a, 418b, and 418c extend from the opposite ends of the base 302b, as shown. Figure 3cAs shown, concentric walls 306b, 304b, and 314b extend from the opposite ends. Each of the inlets 416a, 416b, 416c, 418a, 418b, and 418c can be adapted to receive a corresponding fitting from pipes 412a and 412b at the outer edge of the inlets 416a, 416b, 416c, 418a, 418b, and 418c. For example, each of the three inlets 416a, 416b, and 416c can be adapted to receive a corresponding fitting from controller pipe 412a, and each of the three inlets 418a, 418b, and 418c can be adapted to receive a corresponding fitting from garment pipe 412b. For example, in a first orientation, each of the three inlets 416a, 416b, 416c can be adapted to receive corresponding fittings 422a, 422b, 422c from controller conduit 412a, respectively, and each of the three inlets 418a, 418b, 418c can be adapted to receive corresponding fittings 422a, 422b, 422c from garment conduit 412b, respectively. Conversely, in a second orientation, for example, each of the three inlets 416a, 416b, 416c can be adapted to receive corresponding fittings 422a, 422b, 422c from controller conduit 412a, respectively, and each of the three inlets 418a, 418b, 418c can be adapted to receive corresponding fittings 422c, 422b, 422a from garment conduit 412b, respectively.

[0093] In some respects, the first connector portion 408 may be made of a rigid material, and the second connector portion 410 may be made of a flexible material. The rigid material may be made of polyvinyl chloride (PVC), polyurethane, acrylonitrile-butadiene-styrene (ABS), or similar materials. The flexible material may be made of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), or similar materials. By having a first connector portion 408 made of a rigid material and a second connector portion 410 made of a flexible material, connecting the first connector portion 408 and the second connector portion 410 can be easier due to the flexibility of the second connector portion 410 compared to the case where the first connector portion 408 and the second connector portion 410 are made of the same material. However, in other respects, the first connector portion 408 and the second connector portion 410 may be made of the same material.

[0094] Refer again Figure 3a , Figure 3b and Figure 3c The first connector portion 308 and the second connector portion 310 (similar to) Figure 1 The first connector portion 108 and the second connector portion 110, and Figure 4a and Figure 4b The first connector portion 408 and the second connector portion 410 may include contact pads 332, such as handles, non-slip handles, or textured handles on the outer concentric walls 306a and 306b. For example, the first connector portion 308 may include contact pads 332 located on the top and / or bottom of the outer concentric wall 306a. In another example, the second connector portion 310 may include contact pads 332 located on the top and / or bottom of the outer concentric wall 306b. The contact pads 332 can facilitate the connection between the first connector portion 308 and the second connector portion 310 by providing a non-slip surface. The material of the contact pad may be similar to the material of connector parts 308 and 310, namely, acrylonitrile butadiene styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), nylon (PA), polyurethane (PU), ABS resin, PC resin, polybutylene terephthalate (PBT), polyether ether ketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic acid), POM (Acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon); high-density polyethylene (HDPE), liquid crystal polymer (LCP), low-density polyethylene (LLDPE), linear low-density polyethylene (LLDPE), ultra-high molecular weight polyethylene (UHMW), or any combination thereof.

The corners of the outer concentric walls 306a, 306b and the intermediate concentric walls 304a, 304b can be rounded. As shown, the inner concentric wall 314a of the first connector portion 308 and the inner concentric wall 314b of the second connector portion 310 can be circular or elliptical.

As shown, 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 can have elliptical or circular shapes. The outer concentric walls 506a, 506b are similar to... Figure 3b and Figure 3c The outer concentric walls 306a and 306b shown, and Figure 4a and Figure 4b The examples shown are 406a and 406b.

For example, the notch in the outer concentric wall 506a can receive the sealing member 542a, the notch in the middle concentric wall 504a can receive the sealing member 542b, and the notch in the inner concentric wall 514a can receive the sealing member 542c.

The reversible connector 720 having the first connector portion 708 and the second portion 710 is similar to... Figure 1The reversible connector 120, the first connector portion 108, and the second connector portion 110 are shown. Figures 3a to 3c The reversible connector 320, the first connector portion 308, and the second connector portion 310 are shown.

When the first connector portion 708 and the second connector portion 710 engage, Figure 6 The use of the sealing members 642a, 642b, and 642c shown allows for easier connection. In some aspects, the first connector portion 708 can be made of a rigid material, while the concave connector portion 710 can be made of a flexible material. In other aspects, the first connector portion 708 and the second connector portion 710 can be made of the same material.

The first connector portion has a sealing member surrounding an outer concentric wall, and the second connector portion has a gasket 860. The first connector portion 808 and the second connector portion 810 are similar to... Figure 1 The first connector portion 108 and the second connector portion 110 shown are... Figures 3a to 3cThe first connector portion 308 and the second connector portion 310 shown are... Figure 4a and Figure 4b The first connector portion 408 and the second connector portion 410 shown, and Figure 7a and Figure 7b The first connector portion 708 and the second connector portion 710 are shown.

[0104] like Figure 8a As shown, the first connector portion 808 may include an outer concentric wall 806a having a circumferential notch (not shown), in which a sealing member, such as an O-ring 842a, is positioned. The sealing member 842a is similar to... Figure 5b The sealing member 542a and shown Figure 6 The sealing member 642a shown. Figure 8b A second connector portion 810 is shown, having an outer concentric wall 806b and a washer 860 having a middle concentric wall 844 and an inner concentric wall 850. As shown, the washer 860 is positioned within the outer concentric wall 806b of the second connector portion 810. The washer 860 can be made of a flexible material. The flexible material of the washer 860 allows for easier insertion into the outer concentric wall 806b compared to inserting a non-flexible washer 860. The flexible material of the washer 860 also allows for easier connection between the first connector portion 808 and the second connector portion 810. Alternatively, the washer can be made of a rigid material.

[0106] Figure 8d Washer 860 is shown. Washer 860 may be made of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), or similar materials. The intermediate concentric wall 844 and inner concentric wall 850 of washer 860 may replace the intermediate concentric wall 304b and inner concentric wall 314b of the aspects of this disclosure described above with respect to the second connector portion 310 (similar to the second connector portion 810). Figure 3c (As shown in the diagram). The intermediate concentric wall 844 of the washer 860 may include 326a, 326b, 326c, which replace the aspects of this disclosure described above with respect to the second connector portion 310 (as shown in the diagram). Figure 3c The fluid flow paths 846a, 846b, and 846c (as shown) may include the intermediate concentric walls 844, which may replace the raised blocks 330a and 330b of the prior aspects of this disclosure described above with respect to the second connector portion 310 (as shown). Figure 3c The raised blocks 848a and 848b are shown in the figure.

[0107] like Figure 8a and Figure 8a As shown, when the first connector portion 808 and the second connector portion 810 are slidably engaged, the sealing member 842a (as shown) Figure 8a The use of (as shown) can help with chamber 702 (such as Figure 7a and Figure 7b (As shown) a seal is formed. When the first connector portion 808 and the second connector portion 810 are engaged, the use of the sealing member 842a and the gasket 860 allows for easier connection.

[0108] According to another aspect of the invention, and referring back to Figure 4a and Figure 4bFor example, for use on a pressurized garment (not shown) with fewer than three inflatable bladders, only one or two fittings 422a, 422b, 422c of the garment conduit 412b may be required. In such embodiments, the garment conduit 412b may include only those fittings 422a, 422b, 422c necessary for operating the pressurized garment according to this embodiment; for example, only one fitting 422a for a single-bladder pressurized garment (not shown). For example, if the pressurized garment includes only one fitting 422a, the user can connect fitting 422a to any one of the inlets 416a, 416b, 416c. During setup and initialization cycles, the controller can individually deliver small flows of pressurized fluid to each of the inlets 416a, 416b, 416c and individually determine whether inlets 416a, 416b, 416c are connected to fitting 422a. If the controller determines that any one or more of inlets 416a, 416b, 416c are not connected to fitting 422a, the controller will then supply pressurized fluid only to those inlets where fitting 422a is present. In this way, the reversible connector is adapted to be used with any combination of fittings 422a, 422b, 422c connected to inlets 416a, 416b, 416c.

[0109] Figures 9a to 9d A perspective view of an exemplary reversible connector according to aspects of this disclosure is shown. Variations may include a first connector portion 908, a second connector portion 910, and / or a third connector portion 912. While the first connector portion 908, the second connector portion 910, and the third connector portion 912 are... Figure 9a The diagram is shown in a specific configuration (i.e., the first connector portion 908 engages with the second connector portion 910, and the conduit 913 connects the second connector portion 910 to the third connector portion 912), but the described connectors and aspects are applicable to any configuration. Figure 9a In the example shown, the third connector portion 912 can be, for example, a controller connector configured to connect to a controller (e.g., the one described above). Figure 1 Controller 102 and / or the following Figures 9q to 9s The controller 902 is connected to and provides fluid communication with the controller. Furthermore, the first connector portion 908 can be provided with communication with the pressure garment (e.g., [missing information]) via the pressure garment conduit 942. Figure 1 Fluid communication between the inflatable bladders (e.g., bladders 106a, 106b, and / or 106c) of the pressurized garment 104. Figure 9aAs shown, the third connector portion 912 and the second connector portion 910 can be connected via a conduit 913. The conduit 913 provides fluid communication between corresponding channels of the third connector portion 912 and the second connector portion 910. The conduit 913 may, for example, have three separate channels or conduits 922a, 922b, and 922c therein. In one example, the conduit 913 may be connected to the one described above. Figure 2a and Figure 2b Or the following Figure 11a and Figure 11b The description of pipes 212 or 213 is similar.

[0110] The first connector portion 908 and the second connector portion 910 may alternatively be referred to as a convex connector and a concave connector, respectively, and the third connector portion 912 may alternatively be referred to as a convex connector. The first connector portion 908, the second connector portion 910, and / or the third connector portion may be similar to... Figure 1 The controller-side first connector portion 108a and the sleeve-side reversible second connector portion 110a are shown. Figures 3a to 3c The first connector portion 308 and the second connector portion 310 shown are... Figures 4a to 4b The first connector portion 408 and the second connector portion 410 shown are illustrated. Figures 5a to 5c The first connector portion 508 and the second connector portion 510 shown are... Figures 7a to 7b The first connector portion 708 and the second connector portion 710 and / or Figures 8a to 8d The first connector portion 808 and the second connector portion 810 are included. Additionally, the first connector portion 908 can, for example, be connected to... Figure 1 The sleeve-side connection portion 110a is similar to the first reversible connection portion 108b. Additionally, the second connector portion 910 may be similar to the first reversible connection portion 108b, and the third connector portion 912 may be similar to the second reversible connector portion 110b. The third connector portion 912 may, for example, be connected to a controller (e.g., Figure 1 The controller 102 in the controller (and / or may be configured to connect to the reversible connector portion on the controller side (e.g., Figure 1 (The controller-side reversible first connection portion 108a in the middle).

[0111] Figure 9a A first connector portion 908 connected to the second connector portion 910 is shown. While not limited to the foregoing configuration, the first connector portion 908 can be provided, for example, via a pressure garment conduit 942 to a pressure garment (e.g., Figure 1 The fluid communication between the pressurized garment 104 and the third connector portion 912 is shown as disconnected and can be configured to connect to a controller (e.g., Figure 1 Controller 102 and / or Figures 9q to 9s (Controller 902 in the text). See below for reference. Figure 9q and Figure 9s Provide a detailed example of the reversible connection on the controller side. Figure 9b A perspective view of the first connector portion 908 is shown. Figure 9c A perspective view of the second connector portion 510 is shown, and Figure 9d An example of the third connector section 912 is shown. (Regarding the description below...) Figures 9e to 9r and Figures 12a to 15b Further details of the connector section are described in detail.

[0112] As shown in the figure, the first connector portion 908 may have an outer housing 915a and a sealing member 909a, the sealing member having an outer wall 906a, a middle concentric wall 904a and an inner concentric wall 914a. Figure 9c This is a view of the second connector portion 910, which is disconnected from the first connector portion 908. Note that... Figure 9c The orientation of the second connector portion 910 is for visual clarity and does not necessarily indicate assembly orientation. For example... Figure 9c As shown, 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 (e.g., as shown in the diagram), Figure 9a As shown, the outer wall 906a, intermediate concentric wall 904a, and inner concentric wall 914a of the sealing member 909a can be sealingly engaged with the outer sealing engagement wall 906b, intermediate concentric wall 904b, and inner concentric wall 914b, respectively, to create a chamber forming 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, intermediate concentric wall 904c, and inner concentric wall 914c. In some aspects, the sealing member 909c of the third connector portion 912 can be the same as the sealing member 909a of the first connector portion 908, which can reduce production costs and / or provide easy replacement or reprocessing of connectors and / or related equipment (e.g., pressure garments, adapters, extension devices, and / or controllers).

[0113] like Figure 9e As shown, the first connector portion 908 may include a first connector outer housing 915a. (As indicated...) Figure 9f and Figure 9g As shown, the outer housing 915a may be a component separate from the sealing member 909a. (Go to...) Figure 9gThe sealing member 909a may be a single integral structure and may include an outer concentric wall 906a, a middle concentric wall 904a, and an inner concentric wall 914a. The sealing member 909a may also include a first opening 991a corresponding to a first fluid channel 1 of the first connecting portion, a second opening 992a corresponding to a second fluid channel 2 of the first connecting portion 912, and a third opening 993a corresponding to a third fluid channel 3 of the first connecting portion 912. The inner concentric wall 914a may be positioned within the middle concentric wall 904a, and the middle concentric wall 904a may be positioned within the outer concentric wall 906a in the first connector portion 908. The sealing member 909a may be formed of a flexible or semi-flexible material. The sealing member 909a may also include one or more support structures (e.g., Figure 9g (929a in the original text). The support structure may include a material segment with a larger cross-sectional area than the remainder of the sealing member 909a, and may prevent buckling or otherwise damage to the seal or leakage at the interface between the first connector portion 908 and the second connector portion 910 from any one or combination of the first outer concentric wall 906a, the intermediate concentric wall 904a, and / or the inner concentric wall 914b. The first connector outer housing 915a may be formed, for example, of a rigid or semi-rigid material. Although in Figure 9l The accompanying drawings refer only to a single support structure to prevent obstruction, but any number of support structures can be used without departing from the scope of this disclosure. For example, such as Figure 9lAs shown, the sealing portion 929b may have 14 support structures. In one example, the sealing member may be molded, additively manufactured, extruded, and / or machined from any one or combination of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic vulcanizate (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam, and / or open-cell PE foam or the like. In a preferred aspect, the sealing portion 929b is injection-molded low-hardness polyvinyl chloride (PVC). For example, the outer shell 915a may be molded, additively manufactured, extruded, and / or machined from any or a combination of acrylonitrile-butadiene-styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), nylon (PA), polyurethane (PU), ABS resins, PC resins, polybutylene terephthalate (PBT), polyetheretherketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic acid), POM (Acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon); high-density polyethylene (HDPE), liquid crystal polymer (LCP), low-density polyethylene (LLDPE), linear low-density polyethylene (LLDPE), ultra-high molecular weight polyethylene (UHMW), or the like. In a preferred embodiment, the outer shell 915a is injection-molded acrylonitrile-butadiene-styrene (ABS).

[0114] Now for reference Figure 9h and Figure 9iThe second connector portion 910 may include a second connector outer housing 915b, an outer concentric wall 906b, a middle concentric wall 904b, and an inner concentric wall 914b. The inner concentric wall 914b may be positioned within the middle concentric wall 904b, and the middle concentric wall 904b may be positioned within the outer concentric wall 906b of the second connector portion 910. In an exemplary embodiment, the second connector outer housing 915b, outer concentric wall 906b, middle concentric wall 904b, and inner concentric wall 914b may be formed as a single integral assembly. In one example, the second connector outer housing 915b, outer concentric wall 906b, middle concentric wall 904b, and inner concentric wall 914b may be formed, for example, from a rigid or semi-rigid material. For example, the outer housing 915b, outer concentric wall 906b, middle concentric wall 904b, and inner concentric wall 914b of the second connector may be molded, additively manufactured, extruded, and / or machined from any or a combination of acrylonitrile-butadiene-styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), nylon (PA), polyurethane (PU), ABS resins, PC resins, polybutylene terephthalate (PBT), polyetheretherketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic acid), POM (Acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon); 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 915b, outer concentric wall 906b, middle concentric wall 904b, and inner concentric wall 914b of the second connector are injection-molded acrylonitrile-butadiene-styrene (ABS).

[0115] Now go 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 throughout the disclosure as a convex connector. Figure 9k and Figure 9l As shown, the outer housing 915c may be a component separate from the sealing member 909c. (Go to...) Figure 9lThe sealing member 909c can be a single integral structure and may include an outer concentric wall 906c, a middle concentric wall 904c, and an inner concentric wall 914c. The inner concentric wall 914c can be positioned within the middle concentric wall 904c, and the middle concentric wall 904c can be positioned within the outer concentric wall 906c in the first connector portion 908. The sealing member 909c may also include a first opening 991c corresponding to the first fluid channel 1 of the third connection portion, a second opening 992c corresponding to the second fluid channel 2 of the third connection portion 912, and a third opening 993c corresponding to the third fluid channel 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 also include one or more support structures (e.g., Figure 9l (929c in the text). The support structure may include a section of material having a larger cross-sectional area than the remainder of the sealing member 909a, and may prevent buckling, "blowing-out," or otherwise damage to the seal or cause damage to the third connector portion and the connector connected thereto (e.g., as described below). Figures 9q to 9sLeakage at the interface between the controller side or the fourth connector 941a and / or 941b). In one aspect, the third connector may be configured to connect to a connector having features similar to or the same as those of the second connector portion 910. In one example, the sealing member 909c may be molded, additively manufactured, extruded, and / or machined from any one or combination of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic vulcanizate (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam, and / or open-cell PE foam or the like. In a preferred aspect, the sealing portion 909c is injection-molded low-hardness polyvinyl chloride (PVC). For example, the outer shell 915c may be molded, additively manufactured, extruded, and / or machined from any or a combination of acrylonitrile-butadiene-styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), nylon (PA), polyurethane (PU), ABS resins, PC resins, polybutylene terephthalate (PBT), polyetheretherketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic acid), POM (Acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon); high-density polyethylene (HDPE), liquid crystal polymer (LCP), low-density polyethylene (LLDPE), linear low-density polyethylene (LLDPE), ultra-high molecular weight polyethylene (UHMW), or the like. In a preferred aspect, the outer shell 915c is injection-molded acrylonitrile-butadiene-styrene (ABS). As described below, the third connector may include one or more fastening portions 918, which are configured to have a fastening or tag connection portion passing through them. Reference is made below. Figure 9r Further examples illustrating the function of the tethered portion.

[0116] Now go to Figure 9m and Figure 9n The following describes an example of a fluid path. A first connector portion may include a pipe connection portion 985a, and a second connection portion may include a pipe connection portion 985b, which may be removably or permanently connected to, for example... Figure 1 Pipes 112b, 112c and / or 112a in the middle, Figure 2a and Figure 2b Pipes 212 or 213 in the middle, Figures 4a to 4b Pipes 422a to 422c in the middle, Figures 7a to 7b Pipes 722a to 722c in the middle, Figure 9a and Figure 9r Pipes 913 and / or 942 in the middle.

[0117] Although Figure 9m and Figure 9n The reference connectors in the diagram are the first connector portion 908 and the second connector portion 910, but the same aspects can be applied to the third connector portion 912 and / or the fourth connector or the controller-side connector (e.g., Figures 19a to 19c The controller-side connectors 1914a and / or 1914b are included. In some aspects, the outer concentric wall 906a, the intermediate concentric wall 904a, and the inner concentric wall 914a of the first connector portion 908 can be adapted (i.e., their dimensions are set to) be compatible with... Figure 9e The outer concentric wall 906b, the middle concentric wall 904b, and the inner concentric wall 914b of the second connector portion 910 shown in the diagram are joined to form a reversible connector 920 in a joined configuration, as shown. Figure 9a , Figure 9m and Figure 9n As shown. For example, as Figure 9m and Figure 9n As shown, the outer concentric wall 906a of the first connector portion 908 can engage with the outer surface of the outer concentric wall 906b of the second connector portion 910. The middle concentric wall 904a of the first connector portion 908 can engage with the outer surface of the middle concentric wall 904b of the second connector portion 910. Furthermore, when the first connector portion 908 and the second connector portion 910 are engaged to form a reversible connector 920 in a first engagement configuration, the inner concentric wall 914a of the first connector portion 908 can engage with the outer surface of the inner concentric wall 914b of the second connector portion 910, as shown. Figure 9m As shown.

[0118] like Figure 9n As shown 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., an "inverted" configuration) without changing the order of the fluid communication paths. For example, the first connector portion 908 may have a pipe connection portion 985a having three separate fluid paths (e.g., paths 1, 2, and 3). Similarly, the second connector portion 910 may have a pipe connection portion 985b having three separate fluid paths (e.g., paths 1, 2, and 3). Figure 9mAs shown, in the first engagement configuration, the fluid paths 1, 2, and 3 of the first connector portion 908 and the second connector portion 910 are matched in a corresponding order and flow in the first fluid flow groove. In the case of a connection "reversal" as indicated by arrow 980 (e.g., one of the first connector portion 908 or the second connector portion 910 is flipped 180 degrees), due to the aforementioned concentric wall arrangement, the fluid paths 1, 2, and 3 of the first connector portion 908 and the second connector portion 910 still match when flowing in the second fluid flow groove. As follows regarding... Figures 19a to 19c As described in further detail, features such as the funnel portion 917 improve the consistency of fluid flow and pressure, regardless of the orientation of the connection with the first connector portion 908 and the second connector portion 910. Figure 9m and Figure 9n As shown, the first connector portion 908 and the second connector portion 910 may have corresponding first connector engagement portions 916a and 916b. The first connector engagement portion 916a may be configured to mate within the second connector engagement portion 916b. The engagement between the first connector engagement portion 916a and the second connector engagement portion 916b may, for example, serve as a guide for connecting the first connector portion 908 to the second connector portion 910. In one example, either or a combination of connector portions may have locking features to ensure positive connection and a sealed engagement between two or more connectors. An example of such a feature is shown. Figures 9a to 9dIn the example shown, the locking feature 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 move into or out of engagement with the locking portion 945b of the second connector portion 910. In one example, 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 elements configured to plastically deform or deflect when the user presses the locking portion. The second connector locking feature may, for example, include one or more openings 943 configured to lockably receive the locking portion 945a of the first connector portion 908. Once the first connector portion 908 and the second connector portion are connected and in a sealed engagement, the aforementioned locking feature may, for example, lock the first connector portion 908 into place. When a user presses the first connector portion 908 into the second connector portion 910 until the locking portion 945a is locked into one or more openings 943, the first connector portion 908 and the second connector portion 910 can be locked. When the user wishes to remove the first connector portion 908 from the second connector portion 910, applying pressure to the pressing portion 944a moves the locking portion 945a downward and disengages it from 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 similar features, including the pressing portion 944c and / or the locking portion 945c. Although in Figure 9a While concealed, any 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 locking device may be included on one or both sides of each of the aforementioned first connector portion 908 and / or second connector portion 910. Any of the aforementioned locking features may include visual, tactile, and / or auditory indicators to indicate to the user that the connector is correctly connected. An example of a visual indicator will be referenced below. Figure 12a and Figure 12b Further description.

[0119] like Figure 9o and Figure 9pAs shown, the aforementioned sealing engagement between the first connector portion 908, the second connector portion 910, and / or the third connector portion 912 can be a friction fit or an interference fit type interface. For example, the outer concentric wall 906a of the first connector portion 908 can slidably or frictionally engage 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 can be formed of a more flexible material than the outer concentric wall of the second connector portion 910. In the aforementioned example, the outer concentric wall 906a of the first connector portion 908 can have substantially the same or slightly smaller internal dimensions than the outer concentric wall 906b of the second connector portion 910. Therefore, when the two connectors are connected by a 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 the two outer concentric walls that does not allow fluid loss or only allows minimal fluid loss at the interface. Similarly, the central concentric wall 904a of the first connector portion 908 can slidably or frictionally engage with the outer surface of the central concentric wall 904b of the second connector portion 910. When the first connector portion 908 and the second connector portion 910 are engaged to form a reversible connector 920 in a first engagement configuration, the inner concentric wall 914a of the first connector portion 908 can also slidably or frictionally engage with the outer surface of the inner concentric wall 914b of the second connector portion 910. Figure 9p A close-up view shows the frictional or interference fit between the outer concentric wall 906a of the first connector portion 908 and the outer concentric wall 906b of the second connector portion 910, the intermediate concentric wall 904a of the first connector portion and the intermediate concentric wall 904b of the second connector portion 910, and the inner concentric wall 914a of the first connector portion 908 and the inner concentric wall 914b of the second connector portion 910. While the reference connector described above is the first connector portion 908 and the second connector portion 910, the same aspects can be applied to the third connector portion 912 and / or the fourth connector or the controller-side connector (e.g., Figures 9q to 9s (Controller-side connectors 941a and / or 941b).

[0120] Figure 9q A partial view of an example controller 902 with two controller-side reversible connector portions 941a and 941b is shown. The controller 902 can, for example, be connected to... Figure 1 The controller 102 is similar. Additionally, any one or both of the reversible connectors on the controller side can be connected to... Figure 1 The first connector portion 108a or 108b or the second connector portion 110a or 110b in the middle Figures 3a to 3c The first connector portion 308 or the second connector portion 310 in the middle Figures 4a to 4bThe first connector portion 408 or the second connector portion 310 in the middle Figures 5a to 6 The first connector portion 508 or the second connector portion 510 in the middle Figures 7a to 7b The first connector portion 708 or the second connector portion 710 and / or Figures 8a to 8d The first connector portion 808 or the second connector portion 810, or a combination thereof, are similar.

[0121] exist Figure 9r In the example shown, the reversible connector has a third connector portion 912 and a second connector portion 910, wherein a conduit 913 connects 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 can be configured to sealably engage with the reversible connector (e.g., the third connector portion 912). Either or both of the controller-side reversible connection portions 941a and / or 941b can have a locking feature with one or more locking portions 942a and / or 942b. The locking portions 942a and / or 942b can be configured to lock into engagement with the locking portion 945c of the third connector portion 912 when the third connector is pressed into the controller-side connection portion 941. In one aspect, pressing the pressing portion 944c of the third connector portion ( Figure 9a This causes the locking portion 945c to disengage from one or more locking portions 942a and / or 942b of the controller-side connection portion 944.

[0122] In one aspect, the controller body or controller body connection portion may include a monitor-side tethering portion corresponding to each monitor-side connection portion 941a and / or 941b. The monitor-side tethering portion 919 may be configured to have a tie or tag passing through it. In one example, both the monitor-side tethering portion 919 and one or more tethering portions 918 of the third connector portion 912 may have a tie or tag passing through them. Passing a tie through both the third connector tethering portion 918 and the monitor-side tethering portion 919 can prevent the connector from being accidentally removed from the monitor. In another example, delivering a tag through either or both of the third connector tethering portion 918 and the monitor-side tethering portion 919 can, for example, provide information related to the patient and / or the device to a user or technician, to name just a few non-limiting examples.

[0123] Figure 9sA cross-sectional view is shown of the engagement between one of the two controller-side reversible connection portions 941a and / or 941b. One or both of the two controller-side reversible connection portions 941a and / or 941b are alternatively referred to throughout the disclosure as concave connectors. As described above, either or both of the controller-side reversible connector portions can be coupled with… Figure 1 The first connector portion 108a or 108b or the second connector portion 110a or 110b in the middle Figures 3a to 3c The first connector portion 308 or the second connector portion 310 in the middle Figures 4a to 4b The first connector portion 408 or the second connector portion 310 in the middle Figures 5a to 6 The first connector portion 508 or the second connector portion 510 in the middle Figures 7a to 7b The first connector portion 708 or the second connector portion 710 and / or Figures 8a to 8d The first connector portion 808 or the second connector portion 810, or a combination thereof, are similar. In one example, one or both of the two controller-side reversible connection portions can be connected to the controller via a conduit. For example... Figure 9sAs shown, the aforementioned sealing engagement between the third connector portion 912 and the controller-side reversible connection portion 941 can be a friction fit or interference fit type interface. For example, the outer concentric wall 906c of the third connector portion 908 can slidably or frictionally engage with the outer surface of the outer concentric wall 906d of the monitor-side reversible connector portion 941. The outer concentric wall 906c of the third connector portion 912 can be formed of a material more flexible than the outer concentric wall of the controller-side reversible connector portion 941. Without departing from the scope of this disclosure, the foregoing example can be reversed (e.g., the outer concentric wall 906d of the controller-side connector portion 941 can be formed of a material more flexible than the outer concentric wall 906c of the third connector portion 912). In another example, the outer concentric wall 906c of the third connector portion 912 can be formed of a material with the same or similar flexibility as the outer concentric wall 906d of the controller-side reversible connector portion 941. In the aforementioned example, the outer concentric wall 906c of the third connector portion 912 may have internal dimensions substantially the same as or slightly smaller than the outer concentric wall 906d of the controller-side reversible connection portion 941. Therefore, 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 monitor-side reversible connection portion 941, forming a seal between the two outer concentric walls that does not allow fluid loss or only allows minimal fluid loss at the interface. Similarly, the intermediate concentric wall 904c of the third connector portion 912 may slidably or frictionally engage with the outer surface of the intermediate concentric wall 904d of the monitor-side reversible connection portion 941. When the third connector portion 912 engages with the monitor-side reversible connection portion 941 in a first engagement configuration, the inner concentric wall 914c of the third connector portion 912 may also slidably or frictionally engage with the outer surface of the inner concentric wall 914d of the monitor-side reversible connection portion 941.

[0124] Now go to Figure 10a and Figure 10b An exemplary rear or rear side of the sealing member 1009 is shown. The sealing member 1009 can be used with... Figure 9b , Figure 9e , Figure 9g , Figures 9m to 9p The sealing member 909a and / or shown Figure 9a , Figure 9d and Figures 9j to 9lThe sealing member 909c shown is similar. For example, in addition to the aforementioned features of sealing members 909a and / or 909c, sealing member 1009 may include a rear engagement portion 1054 having a rear engagement portion outer seal 1056 and a first alignment angle 1055a and a second alignment angle 1055b. The rear engagement portion 1054 on the back or rear side of sealing member 1009 may be configured to mate with the connector portion interface 1064 of connector portion 1008. Connector portion 1064 may be coupled with... Figure 1 The controller-side first connector portion 108a and the sleeve-side reversible second connector portion 110a are shown. Figures 3a to 3c The first connector portion 308 and the second connector portion 310 shown are... Figures 4a to 4b The first connector portion 408 and the second connector portion 410 shown are illustrated. Figures 5a to 5c The first connector portion 508 and the second connector portion 510 shown are... Figures 7a to 7b The first connector portion 708 and the second connector portion 710 and / or Figures 8a to 8d The first connector portion 808 and the second connector portion 810 are similar. Additionally, the connector portion 1008 can, for example, be with... Figure 1 The sleeve-side connection portion 110a is similar. The connector portion interface 1064 may include an outer seal receiving portion 1066, a first horn receiving portion 1065a, and a second horn receiving portion 1065b. Therefore, the connector portion interface 1064 of the connector portion 1008 can be configured to engage with the rear engagement portion 1054 of the sealing member 1009. For example, the outer seal 1056 of the rear engagement portion 1054 may be a protruding section of the sealing member 1009 configured to be received by the outer seal receiving portion 1066 of the connector portion interface 1064. Similarly, the second or first horn receiving portion 1065a may be configured to engage with and otherwise receive the first aligned horn 1055a, and the second horn receiving portion 1065b may be configured to engage with and otherwise receive the second aligned horn 1055b. The aforementioned configuration ensures that the sealing member 1009 is installed in the correct orientation during the manufacture and / or refurbishment of the reversible connector.

[0125] Figure 11a This is a top cross-sectional view of an example of a reversible connector, showing the interaction between conduit 1113 and first connector portion 1110 and second connector portion 1112. The first connector portion 1110 and second connector portion 1112 may be similar to... Figure 1 The controller-side first connector portion 108a and the sleeve-side reversible second connector portion 110a shown are... Figures 3a to 3cThe first connector portion 308 and the second connector portion 310 shown are... Figures 4a to 4b The first connector portion 408 and the second connector portion 410 shown are illustrated. Figures 5a to 5c The first connector portion 508 and the second connector portion 510 shown are... Figures 7a to 7b The first connector portion 708 and the second connector portion 710 and / or Figures 8a to 8d The first connector portion 808 and the second connector portion 810 are included. Additionally, the first connector portion 1108 can, for example, be connected to... Figure 1 The sleeve-side connection portion 110a is similar to the first reversible connection portion 108b. Additionally, the second connector portion 1110 may be similar to the first reversible connection portion 108b, and the third connector portion 1112 may be similar to the second reversible connector portion 110b. The first reversible connection portion 1112 may also be similar to... Figure 9a , Figure 9d , Figure 9j , Figure 9k and Figure 9l The third connector portion 912 is similar and can be connected to a controller (e.g., Figure 1 Controller 102 and / or Figures 9q to 9s The controller 902 in the middle) and / or can be configured to connect to the reversible connector portion on the controller side (e.g., Figure 1 The controller-side reversible first connection portion 108a and / or Figures 9q to 9s (The controller-side reversible connection portions 941a and / or 941b in the middle).

[0126] Figure 11a This illustrates an aspect of the present disclosure that can be utilized between a fluid source controlled by a controller and a pressurized garment. Figure 11a The cross-section of pipe 1113. The pipe profile of pipe 1113 can be implemented in connectors and / or sleeves (e.g., Figure 1 (in the bushing 100) and / or controller (e.g., Figure 1 Controller 102 and / or Figures 9q to 9s A fluid path is created between each of the controllers (902) in the system. For example, pipe 1113 can be used as... Figure 1 The controller conduit 112a and the pressurized garment conduit 112b are shown. Conduit 1113 can also be connected to... Figure 9a and Figure 9r The same applies to pipe 913. Pipe 1113 may include three separate fittings or fitting channels or conduits 1123a, 1123b, and 1123c, which may correspond to a controller (e.g., Figure 1 Controller 102 and / or Figures 9q to 9s The controller 902 and the pressure garment 104 (in the middle) Figure 1 The three bladders 106a, 106b, and 106c create a fluid path between the controller and these three bladders. While three fittings or conduits or pipes 1123a, 1123b, and 1123c are shown, and three bladders are provided as an example, aspects of this disclosure may include more or fewer channels corresponding to the number of inflatable bladders. For example, a conduit may include two channels providing fluid communication with two bladders, or it may include more than three channels providing fluid communication with a corresponding number of bladders. For example, in one exemplary embodiment, a conduit may include four to six channels. In some aspects, conduit 212 may be similar to the above description... Figure 2a The described conduit may additionally include an alignment section 1121. The alignment section 1121 may, for example, include an additional channel or alignment feature 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 conduit 1113 is installed in the correct orientation relative to either connector 1110 or 1112 (e.g., not "flipped"). In an exemplary embodiment of the alignment section 1121, the first connector 1110 and the second connector 1112 may have corresponding first connector alignment sections 1114 and 1115 configured to receive the alignment portion 1121 of the conduit 1113. In addition to the advantages described above, the conduit profile also improves the aesthetics of the conduit and / or the connectors to which it is connected by providing a symmetrical appearance at the interface between the conduit 1113 and the first connector portion 1110 and / or the second connector portion 1112.

[0127] Figure 12a and Figure 12b An example of a locking feature with a visual indicator is shown, which is used to confirm that two or more of the aforementioned reversible connector portions are correctly 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... Figure 1 The controller-side first connector portion 108a and the sleeve-side reversible second connector portion 110a shown are... Figures 3a to 3c The first connector portion 308 and the second connector portion 310 shown are... Figures 4a to 4b The first connector portion 408 and the second connector portion 410 shown are illustrated. Figures 5a to 5c The first connector portion 508 and the second connector portion 510 shown are... Figures 7a to 7b The first connector portion 708 and the second connector portion 710 and / or Figures 8a to 8dThe first connector portion 808 and the second connector portion 810 are included. Additionally, the first connector portion 1208 can, for example, be connected to... Figure 1 The sleeve-side connection portion 110a is similar to the first reversible connection portion 108b. Additionally, 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 connector portion 110b. The first reversible connection portion 1210 may also be similar to... Figure 9a , Figure 9d , Figure 9j , Figure 9k and Figure 9l The third connector portion 912 is similar and can be connected to a controller (e.g., Figure 1 Controller 102 and / or Figures 9q to 9s The controller 902 in the middle) and / or can be configured to connect to the reversible connector portion on the controller side (e.g., Figure 1 The controller-side reversible first connection portion 108a and / or Figures 9q to 9s The controller-side reversible connection portions 941a and / or 941b are also available. The first connector portion 1208 and / or the second connector portion 1210 can also be connected to... Figure 10b Connector part 1008 Figure 11a Similar to 1112 and / or 1110 in the example.

[0128] The locking feature 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 may be biased or otherwise tensioned such that pressing the pressing portion 1244 causes the locking portion 1245 to move into or out of engagement with the locking portion of the second connector 1210. In one example, the pressing portion 1244 and / or the locking portion 1245 may be connected to the first connecting portion 1208 via a plastic biasing member or other element configured to plastically deform or deflect when the user presses the pressing portion 1244. The second connector locking feature may, for example, include one or more openings 1245 configured to lockably receive the locking portion 1245 of the first connector portion 1208. Once the first connector portion 1208 and the second connector portion 1210 are connected and in a sealed engagement, the aforementioned locking feature may, for example, lock the first connector portion 1208 into place. When a user presses the first connector 1208 into the second connector 1210 until the locking portion 1245 is locked into one or more openings 1243, the first connector portion 1208 and the second connector portion 1210 can be locked. When 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 and disengages it from the locking engagement with the one or more openings 1243, thereby allowing the user to separate the first connector portion 1208 from the second connector portion 1210. Any of the aforementioned locking features may include visual, tactile, and / or auditory indicators to indicate to the user that the connector is correctly connected. For example, such as Figure 12bAs shown, the locking portion 1245 of the first connector portion 1208 may include, for example, a visual indication feature as a colored, bright, or contrasting color to provide visual confirmation that the locking portion 1245 of the first connector is fully engaged and locked into the opening 1243 of the second connector portion 1210. Therefore, the aforementioned visual indication can provide the user with confirmation that the first connector 1208 is correctly connected to the second connector 1210 and that a fluid seal has been established between the two connectors. Additionally, pressing the first connector portion 1208 into the second connector causes the locking portion 1245 to be pressed downwards, thus applying tension to the resilient or semi-resilient connection 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 can spring back to a relaxed state, which provides a "click" or similar tactile or audible indication that the first connector 1208 is correctly connected to the second connector 1210 and that a fluid seal has been established between the two connectors. While locking features are preferred, those skilled in the art will understand that aspects of this disclosure still offer advantages for connectors that include a single locking feature or that do not include any locking features.

[0129] like Figure 13a and Figure 13b As shown, any of the aforementioned connectors may include a first or top locking feature 1345, a second or bottom locking feature 1345b, or top and bottom locking features 1345a and 1345b. As an example, the first connector portion 1308 and the third connector portion 1312 are in... Figure 13a and 13b As shown in the diagram. The first connector portion 1308 and the third connector portion 1312 may be similar to Figure 1 The controller-side first connector portion 108a and the sleeve-side reversible second connector portion 110a shown are... Figures 3a to 3c The first connector portion 308 and the second connector portion 310 shown are... Figures 4a to 4b The first connector portion 408 and the second connector portion 410 shown are illustrated. Figures 5a to 5c The first connector portion 508 and the second connector portion 510 shown are... Figures 7a to 7b The first connector portion 708 and the second connector portion 710 and / or Figures 8a to 8d The first connector portion 808 and the second connector portion 810 are included. Additionally, the first connector portion 1308 can, for example, be connected to... Figure 1The sleeve-side connection portion 110a is similar to the first reversible connection portion 108b. Additionally, the third connector portion 1312 can be similar to the first reversible connection portion 108b, and the third connector portion 1312 can be similar to the second reversible connector portion 110b. The first reversible connection portion 1308 can also be similar to... Figure 9a , Figure 9d , Figure 9j , Figure 9k and Figure 9l The third connector portion 912 is similar and can be connected to a controller (e.g., Figure 1 Controller 102 and / or Figures 9q to 9s The controller 902 in the middle) and / or can be configured to connect to the reversible connector portion on the controller side (e.g., Figure 1 The controller-side reversible first connection portion 108a and / or Figures 9q to 9s The controller-side reversible connection portions 941a and / or 941b are included. The first connector portion 1308 or the third connector portion 1312 can also be connected to... Figure 10b Connector part 1008 Figure 11a 1112 and / or 1110 and / or Figure 12a and Figure 12b Similar to 1208 or 1210.

[0130] In one example, when the connection portion, such as the third connector portion 1312, is intended to connect to a surface mount connector or a rigid connector (e.g., Figures 9q to 9s When the controller-side reversible connection portions 941a and / or 941b are included, the third connector portion 1312 may include both top and bottom first features 1345a and 1345b, allowing the user to easily mount the third connector portion in either orientation. In some examples, such as Figure 13a The first connection portion 1308 shown is designed to connect to a non-fixed or surface-mount connector (e.g., Figure 1 The sleeve-side reversible connector portion 110a) of the non-fixed or surface-mount connector connects to another conduit. In this case, it may only be necessary to include a first or top locking feature 1345 on the connection portion, since the two connection portions to be connected can be easily flipped or otherwise aligned before connection.

[0131] Figure 14a and Figure 14b An example of a strain relief feature 1446 is shown, which can be used with any connection portion throughout the description of this disclosure. As an example, the strain relief feature 1446 is shown having a first connector portion 1408 and a third connector portion 1412. The first connector portion 1408 and the third connector portion 1412 may be similar to... Figure 1 The controller-side first connector portion 108a and the sleeve-side reversible second connector portion 110a shown are... Figures 3a to 3c The first connector portion 308 and the second connector portion 310 shown are...

Figures 7a to 7b The first connector portion 708 and the second connector portion 710 and / or Figures 8a to 8d The first connector portion 808 and the second connector portion 810 are included. Additionally, the first connector portion 1408 can, for example, be connected to... Figure 1 The sleeve-side connection portion 110a is similar to the first reversible connection portion 108b. Additionally, the third connector portion 1412 can be similar to the first reversible connection portion 108b, and the third connector portion 912 can be similar to the second reversible connector portion 110b. The first reversible connection portion 1410 can also be similar to... Figure 9a , Figure 9d , Figure 9j , Figure 9k and Figure 9l The third connector portion 912 is similar and can be connected to a controller (e.g., Figure 1 Controller 102 and / or Figures 9q to 9s The controller 902 in the middle) and / or can be configured to connect to the reversible connector portion on the controller side (e.g., Figure 1 The controller-side reversible first connection portion 108a and / or Figures 9q to 9s The controller-side reversible connection portions 941a and / or 941b are also included. The first connector portion 1408 and / or the third connector portion 1412 can also be connected to... Figure 10b Connector part 1008 Figure 11a 1112 and / or 1110 in Figure 12a and Figure 12b 1208 or 1210 and Figure 13a and Figure 13b The numbers 1308 and 1312 are similar.

[0132] The strain relief section 1446 may, for example, include an annular rounded corner section configured to control the movement of the conduit 1413 and prevent kinking or other potentially destructive bending of the conduit. In one example, the strain relief section 1446 may be molded, additively manufactured, and / or machined from any or a combination of acrylonitrile-butadiene-styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), nylon (PA), polyurethane (PU), ABS resins, PC resins, polybutylene terephthalate (PBT), polyetheretherketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic acid), POM (Acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon); 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 aspect, the outer shell 915a is injection-molded acrylonitrile-butadiene-styrene (ABS). In some aspects, the strain-relieving portion 1446 may be formed of a low-hardness material. For example, the strain-relieving portion 1446 may be any one or a combination of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic vulcanizate (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam and / or open-cell PE foam or the like.

[0133] The strain relief portion 1446 allows for flexibility between the conduit 1413 and the connector portion 1412 while preventing kinking of the conduit, which could impede fluid flow and / or damage the conduit 1413.

Figure 15a , Figure 15b and Figure 15c A first connector portion 1508 and a second connector portion 1510 are shown, which can alternatively be referred to as a convex connector and a concave connector, respectively. The first connector portion 1508 and the second connector portion 1510 can be similar to...

Additionally, the first connector portion 1408 may, for example, be connected to... Figure 1 The sleeve-side connection portion 110a in the first reversible connection portion 108b may have features similar to or including those of the sleeve-side connection portion. Additionally, the second connector portion 1510 may have features similar to or including those of the first reversible connection portion 108b, and the third connector portion 912 may have features similar to or including those of the second reversible connector portion 110b. The first reversible connection portion 1508 may also have features similar to or including those of the first reversible connector portion 108b. Figure 9a , Figure 9d , Figure 9j , Figure 9k and Figure 9l The third connector portion 912 in the middle has similar or includes the features of the third connector portion, and is capable of being connected to the controller (e.g., Figure 1 Controller 102 and / or Figures 9q to 9s The controller 902 in the middle) and / or can be configured to connect to the reversible connector portion on the controller side (e.g., Figure 1 The controller-side reversible first connection portion 108a and / or Figures 9q to 9s The controller-side reversible connection portions 941a and / or 941b are also included. The first connector portion 1508 and / or the second connector portion 1510 can also be connected to... Figure 10b Connector part 1008 Figure 11a 1112 and / or 1110 in Figure 12a and Figure 12b 1208 or 1210 in Figure 13a and Figure 13b 1308 and 1312 in Figure 14a and Figure 14b Similar to or including the features of connectors 1408 and 1412.

[0135] like Figure 15a As shown, the first connector portion 1508 may include a first connector outer housing 1515a. The outer housing 1515a may be a component separate from the sealing member 1509 (e.g., similar to...). Figure 9f and Figure 9g (The aspects described in the text). Go to Figure 15cThe sealing member 1509 may be a single integral structure and may include an outer concentric wall 1506a, a middle concentric wall 1504a, and an inner concentric wall 1514a. The inner concentric wall 1514a may be positioned within the middle concentric wall 1504a, and the middle concentric wall 1504a may be positioned within the outer concentric wall 1506a in 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, for example, of a rigid or semi-rigid material. In one example, the sealing member may be molded, additively manufactured, extruded, and / or machined from any one or combination of liquid silicone rubber (LSR), polyvinyl chloride (PVC), thermoplastic elastomer (TPE), thermoplastic vulcanizate (TPV), closed-cell PU foam, open-cell PU foam, closed-cell PE foam, and / or open-cell PE foam or the like. For example, the outer housing 1515a may be molded, additively manufactured and / or machined from any one or combination of polyvinyl chloride (PVC), polyurethane, acrylonitrile-butadiene-styrene (ABS) or the like.

[0136] Now for reference Figure 15a and Figure 15bThe second connector portion 1510 may include a second connector outer housing 1515b, an outer concentric wall 1506b, a middle concentric wall 1504b, and an inner concentric wall 1514b. The inner concentric wall 1514b may be positioned within the middle concentric wall 1504b, and the middle concentric wall 1504b may be positioned within the outer concentric wall 1506b of the second connector portion 1510. In an exemplary embodiment, the second connector outer housing 1515b, outer concentric wall 1506b, middle concentric wall 1504b, and inner concentric wall 1514b may be formed as a single integral assembly. In one example, the second connector outer housing 1515b, outer concentric wall 1506b, middle concentric wall 1504b, and inner concentric wall 1514b may be formed, for example, from a rigid or semi-rigid material. For example, the outer shell 1515b, outer concentric wall 1506b, middle concentric wall 1504b, and inner concentric wall 1514b of the second connector may be molded, additively manufactured, extruded, and / or machined from any or a combination of acrylonitrile-butadiene-styrene (ABS), polycarbonate (PC), polyvinyl chloride (PVC), nylon (PA), polyurethane (PU), ABS resins, PC resins, polybutylene terephthalate (PBT), polyetheretherketone (PEEK), PEI (Ultem), PET, PETG, PMMA (acrylic acid), POM (Acetal / Delrin), PP (polypropylene), polyphenylene ether (PPE), polyphenylene sulfide (PPS), polystyrene (PS), PTFE (Teflon); 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 1515b, outer concentric wall 1506b, middle concentric wall 1504b, and inner concentric wall 1514b of the second connector are injection-molded acrylonitrile-butadiene-styrene (ABS).

[0137] Now go to Figure 15c The following describes an example of a fluid path. A first connector portion 1508 may have a pipe connection section 1585a, and a second connector portion 1510 may have a pipe connection section 1585b. The first connector portion 1608 may have a pipe connection portion 1685, which may be removably or permanently connected to, for example... Figure 1 Pipes 112b, 112c and / or 112a in the middle, Figure 2a and Figure 2b Pipes 212 or 213 in the middle, Figures 4a to 4b Pipes 422a to 422c in the middle, Figures 7a to 7b Pipes 722a to 722c in the middle, Figure 9a and Figure 9rThe conduits 913 and / or 942 in the middle. In some aspects, the outer concentric wall 1506a, the intermediate concentric wall 1504a, and the inner concentric wall 1514a of the first connector portion 1508 can be adapted (i.e., the dimensions are set to) with... Figure 15c The outer concentric wall 1506b, the middle concentric wall 1504b, and the inner concentric wall 1514b of the second connector portion 1510 shown in the diagram engage to form a reversible connector 1520 in an engaged configuration. This configuration allows the first connector portion 1508 and the second connector portion 1510 to engage in a first configuration (e.g., as shown in the diagram). Figure 15c The connectors (as shown) can be connected to follow a first fluid flow groove, or connected in a second engagement configuration (e.g., a "reverse" configuration) to follow a second fluid flow groove within the connector, without altering the order of the fluid communication paths of the three individual fluid paths (e.g., paths 1, 2, and 3). In the case of a "reverse" connection (e.g., one of the first connector 1508 or the second connector 1510 is flipped 180 degrees), fluid paths 1, 2, and 3 of the first connector 1508 and the second connector 1510 still match due to the aforementioned concentric wall arrangement.

[0138] like Figure 15a and Figure 15b As shown, the first connector portion 1508 and the second connector portion 1510 may have corresponding first connector engagement portions 1516a and 1516b. The first connector engagement portion 1516a may be configured to fit within the second connector engagement portion 1516b. The engagement between the first connector engagement portion 1516a and the second connector engagement portion 1516b may, for example, serve as a guide for connecting the first connector portion 1508 to the second connector portion 1510.

[0139] In one example, the first connector portion 1908 may have one or more locking features 1541a (one locking feature 1541a in Figure 15a (Hidden in the middle), the one or more locking features are configured to lock into engagement with one or more locking features 1541b of the second connector portion. In one example, the one or more locking features 1541b of the second connector portion may be an opening sized to receive a corresponding locking feature of the locking feature 1541a of the first connector portion 1508. In one aspect, the locking features 1541a and 1541b of the first connecting portion and the second connector portion may include the above-mentioned... Figures 12a to 13bThe locking feature described herein. In the example shown, the locking feature of the first connector 1541a includes at least one press portion. The press portion of the locking feature 1541a of the first connector 1508 may be biased or otherwise tensioned such that pressing the press portion causes the locking portion 1541a to move into or out of engagement with the locking portion 1541b of the second connector 1510. In one example, the press portion or locking portion 1541a of the first connector 1508 may be connected to the first connection portion via a plastic biasing member or other element configured to plastically deform or deflect when the user presses the locking portion. The locking feature of the second connector may, for example, include one or more openings 1541b configured to lockably receive the locking portion 1541a of the first connector portion 1508. When a user wishes to remove the first connector portion 1908 from the second connector portion 1910, applying pressure to the pressing portion of the locking portion 1541a moves the locking portion 1541a downward and disengages it from 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 of the aforementioned locking features may include visual, tactile, and / or auditory indicators to indicate to the user that the connector is correctly connected. An example of a visual indicator will be referenced above. Figure 12a and Figure 12b Further description.

The first connector portion 1608 and / or the second connector portion 1610 can also be connected to...

The first connector portion 1608 may have a conduit connection portion 1685a, and the second connector portion may have a conduit connection portion 1685b. For example, conduit connection portions 1685a and / or 1685b may be removably or permanently connected to, for example... Figure 1 Pipes 112b, 112c and / or 112a in the middle, Figure 2a and Figure 2b Pipes 212 or 213 in the middle, Figures 4a to 4b Pipes 422a to 422c in the middle, Figures 7a to 7b Pipes 722a to 722c in the middle, Figure 9a and Figure 9r The conduits 913 and / or 942 are included. The first connector portion 1608 may include, for example, a body portion 1615a. The first connector portion 1608 may also 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 be constituted, for example, by a seal (e.g., an O-ring or other flexible seal) contained in a corresponding groove in the body portion 1615a of the first connector portion 1608.

[0141] like Figure 16b and Figure 16c As shown, when the first connector portion 1608 engages with the second 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 1642b corresponding to the first opening 1646b in the first connecting portion, and forms a second chamber 1602 between the second sealing portion 1642b and 1642c corresponding to the second opening 1646c. The first chamber 1604 and the second chamber 1602 allow fluid, such as air, to flow from the first connector portion 1608 to the second connector portion 1610. The first connector and the second connector may additionally include third openings 1646a and 1647a, respectively, which are in direct fluid communication when the first connector portion 1608 is connected to the second connector portion 1610. The aforementioned features allow the first and second connectors to provide fluid communication following corresponding paths 1, 2, and 3, regardless of the orientation of the first connector portion 1608 when it is engaged and connected to the second connector portion 1610. For example, as Figure 16d As shown, the 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 a fluid communication path (1), (2), and (3) from the first connector portion 1608 to the second connector portion 1610, regardless of whether the first connector portion and the second connector portion are connected in a first orientation (e.g., as shown). Figure 16c and / or Figure 16d (as shown) or whether they are flipped 180°.

[0144] Go to Figure 18 The invention discloses an adapter 1819 utilizing a reversible connector (e.g., empty 1810 / 1841) and an irreversible connector 1806. In one exemplary embodiment, the adapter 1819 may be configured, for example, to utilize a controller (e.g., a controller using an irreversible connector) Figure 1 Controller 102 and / or Figures 9q to 9s The controller 902 in the adapter 1819 is connected to or adapted to a system utilizing one or more reversible connectors according to this disclosure.

The adapter 1819 may also include a conduit 1813 for providing fluid communication between each fluid channel in the fluid channels at the irreversible connection portion 1806 and / or the reversible connection portions 1810 / 1841. While not limited to a specific conduit profile, in a preferred embodiment, the conduit may include the above... Figures 2a to 2b Any of the pipe profiles described herein. The irreversible connection portion 1806 may include any known connector capable of connecting to a second corresponding connector, but typically must be connected to the corresponding connector in a single orientation (e.g., cannot be "flipped" 180 degrees when connected to the corresponding connector). The foregoing aspects provide the advantage of allowing the systems, methods, and apparatus of this disclosure to be used with commercially available products (e.g., pressure garments, pipe extensions, and / or controllers) or products that include irreversible connectors or connectors with different connection interfaces. In one example, the reversible connection portions 1810 / 1841 of the adapter 1819 may be a concave connector. Furthermore, the reversible connection portions 1810 / 1841 may be similar to Figure 1 The controller-side first connector portion 108a and the sleeve-side reversible second connector portion 110a are shown.

Figure 1Pressure maps of pressure versus time at bladders 106a, 106b, and 106c. When the connectors are connected in the first configuration 1900a and / or the second configuration 1900b (e.g., when one of the two connectors or connector portions is rotated 180 degrees), the flow path within the connectors described throughout the disclosure provides consistent performance. For example, Figure 19b The fluid pressure diagram illustrates the fluid pressure provided through the first fluid path (1), the second fluid path (2), and the third fluid path (3) when the first connector portion 1908 is connected to the second connector portion 1910 in the first orientation. Figure 19c The fluid pressure diagram shows when the first connector portion 1808 is in a second orientation (e.g., from...).

As shown, switching either the first connector 1908 and / or the second connector portion 1910 from the first orientation to the second orientation has a negligible effect on the pressure provided to each bladder by the controller via the reversible connector.
