Description

Technical Field

[0001] This disclosure generally relates to medical fluid valves, and more specifically, to connector assemblies and collapsible valves modified to control medical fluids supplied by syringes. Background Technology

[0002] For intravenous (“IV”) applications, valves, including needleless access valves, are used to deliver fluid to a patient. When the syringe applies sufficient pressure to the valve, the valve assembly collapses and allows downstream fluid to be delivered from the syringe to the catheter. However, when the syringe is removed from the valve, the valve assembly may not recover or return to its initial position, thus compromising the valve's operation. When these types of problems occur, the IV kit needs to be replaced, leading to increased costs and a negative patient experience. Utility Model Content

[0003] This disclosure provides a connector assembly having a post (e.g., a central post) and a valve positioned on the post. When engaged with a fluid delivery device (e.g., a syringe), the valve displaces (e.g., compresses) relative to the post, causing the post to protrude through the valve. The valve may include one or more features to allow the valve to collapse in an intentional, consistent, and / or uniform manner. Continuous collapse of the valve can minimize valve failure and prevent the valve from jamming or flipping.

[0004] Furthermore, when the fluid delivery device is removed from the connector assembly, the force provided by the fluid delivery device decreases, allowing the valve to cover the support. The valve's features allow it to consistently return to or extend to its original sealing position. Therefore, this valve promotes consistent and reliable operation and prevents valve failure or jamming, even during high-pressure operation, such as forceful injection.

[0005] According to at least some of the embodiments disclosed herein, it is recognized that inconsistent collapse of the valve can cause the valve to buckle or become stuck, which can lead to fluid leakage or accidental fluid administration, potentially causing harm to patients or caregivers, such as by depriving patients of medication, increasing the likelihood of infection in patients, and exposing caregivers to harmful drugs. Furthermore, a stuck or buckled valve renders an IV kit unusable.

[0006] Therefore, aspects of this disclosure provide a connector assembly for use with a conduit, the connector assembly comprising: a first housing including a fluid inlet; a second housing coupled to the first housing, the second housing including a strut defining an opening; and a valve including a channel disposed around the strut to selectively isolate the opening from the fluid inlet, the channel defining a pressure-reducing portion having a reduced valve body thickness, wherein the valve is collapsible relative to the pressure-reducing portion to allow fluid communication between the fluid inlet and the opening.

[0007] Some examples of this disclosure provide a connector assembly for use with a conduit, the connector assembly comprising: a first housing including a fluid inlet; a second housing coupled to the first housing, the second housing including a strut defining an opening; and a valve including an outer surface defining an outer recessed portion having an increased valve body thickness, the valve being disposed around the strut to selectively isolate the opening from the fluid inlet, wherein the valve is collapsible relative to the recessed portion to allow fluid communication between the fluid inlet and the opening.

[0008] Some examples of this disclosure provide a collapsible valve for use with a connector, the valve comprising: a channel configured to selectively isolate from an opening of the connector; and an outer surface defining a plurality of recesses, each of the plurality of recesses having an increased valve body thickness, wherein the valve is collapsible relative to each of the plurality of recesses to allow fluid flow to the opening of the connector.

[0009] Therefore, this application addresses several operational challenges encountered with existing valves (including needleless access valves) used when administering fluids with a syringe, and provides numerous enhancements and improvements for consistent valve collapse and recovery, which can reduce valve flipping, valve jamming, and valve failure.

[0010] Further features and advantages of this subject matter will be set forth in the description which follows, and some features and advantages will become apparent from the description or may be learned by practice of the subject matter. The advantages of this subject matter will be realized and obtained through the written description and embodiments, as well as the structures specifically pointed out in the accompanying drawings.

[0019] In the following detailed description, numerous specific details are set forth to provide a full understanding of the subject matter. The subject matter can be practiced without these specific details. In other instances, well-known structures and techniques are not shown in detail to avoid obscuring the subject matter.

[0020] Furthermore, although this specification sets forth specific details of various embodiments, it should be understood that this specification is illustrative only and should not be construed as restrictive in any way. Moreover, it is conceivable that although specific embodiments of this disclosure may be disclosed or illustrated in the context of IV kits, these embodiments can be used in other fluid delivery systems. Furthermore, various applications and modifications of such embodiments that may occur to those skilled in the art are also included within the general concepts described herein.

[0021] Needleless connectors are fundamental devices for delivering fluids to patients via IV catheters. Needleless connectors can be used in the general patient population, including newborns, children, and adults. Some conventional connectors may include valves that collapse in a random and / or inconsistent manner. In some applications, valves that collapse inconsistently may provide inconsistent activation forces. In some applications, such as high-pressure applications (e.g., power injection procedures), some conventional valves may collapse and self-fold, thus eliminating valve restoring force, or otherwise remain stuck in the open position. Folded or “stuck” valves may not return to normal operation without physical intervention or a complete replacement of the IV kit. The following devices and methods offer design modifications to overcome the aforementioned problems.

[0022] The embodiments described herein can provide improved valve geometry to enhance connector functionality. Furthermore, the embodiments described herein can provide a valve that collapses intentionally, uniformly, and / or evenly to prevent valve failures such as jammed or folded valves. Advantageously, embodiments of the valve may have a bellows with cutouts and / or geometry (e.g., varying thickness and diameter) to allow for folded areas and uniform collapse and recovery of the valve.

[0023] Now refer to the attached diagram, Figure 1 and Figure 2 A perspective view of a connector assembly 100 according to some aspects of this disclosure is shown. The connector assembly 100 may include a housing 102 and a base 104 coupled to the housing 102. The housing 102 and the base 104 may be referred to as a first housing and a second housing, respectively. The housing 102 includes a fluid inlet 106, and the base 104 includes a fluid outlet 108. As shown, the fluid inlet 106 and the fluid outlet 108 are cylindrical or generally cylindrical bodies with a circular cross-section. However, other shapes are also possible. For fluid regulation, the connector assembly 100 includes a valve 110 carried within portions of the housing 102 and the base 104.

[0024] like Figure 2 As shown, connector assembly 100 can be used to provide a connection point for fluid delivery device 150. In some embodiments, fluid delivery device 150 includes a syringe, such as a needle-free syringe. Therefore, in some embodiments, connector assembly 100 may take the form of a needle-free connector assembly. For some exemplary IV applications, fluid delivery device 150 can be used for rapid injection of medication, sometimes referred to as “push” or “ejection,” to rapidly deliver a single dose of medication into the patient’s bloodstream. Fluid delivery device 150 connects to fluid inlet 106 of connector assembly 100 (e.g., ...). Figure 1 (As shown). Furthermore, the fluid outlet 108 of the connector assembly 100 can be connected to the conduit line 109. The valve 110 is positioned to regulate the fluid flow supplied to the conduit line 109 by the fluid delivery device 150.

[0025] Figure 3 and Figure 4 A partial cross-sectional view of a connector assembly 100 according to some aspects of this disclosure is shown. Figure 5 yes Figure 3 and Figure 4 The diagram shows a cross-sectional view of the valve in the connector assembly. The base 104 may include a strut 112 extending into the housing 102. The strut 112 provides a hollow body to facilitate fluid transport through the connector assembly 100. The strut 112 includes a proximal end and a distal end 120, and in some embodiments of this disclosure, the outer surface of the strut defines a cross-sectional width that decreases in the direction from the proximal end to the distal end 120. In some embodiments, the strut 112 may extend further or less into the housing 102 and / or relative to the valve 110. In some embodiments, the base 104 may not include the strut.

[0026] Valve 110 includes a passage 113 that allows valve 110 to receive support 112. For example... Figure 3 and Figure 4As shown, valve 110 surrounds support 112. In some embodiments, valve 110 is disposed on and engages with support 112. As shown, valve 110 may include one or more sealing portions 172 formed within channel 113 to seal against support 112. In some embodiments, sealing portions 172 may be configured to minimize friction as valve 110 moves relative to support 112.

[0027] Furthermore, the support 112 includes an opening 114 (representing one or more openings in the support 112) designed to receive fluid from the fluid inlet 106 of the housing 102. For illustrative purposes, Figure 4 The support 112 is rotated to make the opening 114 visible. (As shown) Figure 4 As shown, the lumen 116 is formed or positioned within the channel 115 of the support 112. Fluid can subsequently flow into the lumen 116 when fluid is received from the opening 114. Thus, the opening 114 is fluidly connected to the lumen 116. To secure the lumen 116, the base 104 includes a Luer element 117.

[0028] based on Figure 3 and Figure 4 The position of valve 110 is shown. Valve 110 is in the closed position and covers opening 114, thereby preventing fluid from flowing into opening 114 of support 112 and into lumen 116. However, valve 110 is designed to regulate flow in part based on displacement (e.g., compression) of valve 110, such that opening 114 is not covered by valve 110, which will be shown and described in detail below. It should be noted that displacement of valve 110 may include resilient displacement (e.g., resilient compression), thereby allowing valve 110 to return to its original form (e.g., when the fluid delivery device is removed / disengaged from valve 110) after displacement. Figure 3 and Figure 4 (As shown).

[0029] In the depicted example, valve 110 may have features, geometries, or otherwise be configured to provide consistent and uniform collapse and prevent valve body 160 from jamming during operation, including high-pressure operation. In some embodiments, valve body 160 may have features or recesses 176 (recesses 176a-176e shown) shaped or arranged to allow valve body 160 to collapse consistently during operation. As shown, recesses 176 may have a generally circular shape and be formed on the outer surface of valve body 160. Recesses 176 may be arranged to give portions of valve body 160 increased thickness and stiffness, while other portions have decreased thickness and stiffness, thereby allowing valve body 160 to collapse in a consistent and desired manner during operation.

[0030] In some embodiments, the valve body 160 may have a pressure-reducing portion 174 (shown as 174a, 174b), which is also shaped or arranged to allow the valve body 160 to collapse uniformly during operation. As shown, the pressure-reducing portion 174 may be a groove, channel, or void formed in the inner surface of the lumen 116 within the valve 110. The pressure-reducing portion 174 may be arranged to provide areas of reduced thickness and stiffness of the valve body 160 to introduce locations where the valve body 160 can collapse uniformly.

[0031] In the described embodiments, the recess 176 and the pressure-reducing portion 174 can be arranged cooperatively to provide regions that increase the stiffness of the valve body 160 and regions that decrease the stiffness of the valve body 160, thereby promoting uniform collapse of the valve 110 during operation. For example, in some embodiments, the pressure-reducing portion 174a may be disposed between the first recess 176a and the second recess 176b to allow the valve body 160 to collapse outward between the first recess 176a and the second recess 176b. Similarly, in some embodiments, the pressure-reducing portion 174b may be disposed between the fourth recess 176d and the fifth recess 176e to allow the valve body 160 to collapse outward between the fourth recess 176d and the fifth recess 176e. In some embodiments, the third recess 176c may be configured to collapse inward. In other words, in some embodiments, the valve body is configured in a “2-1-2” configuration such that the first recess 176a and the second recess 176b are collapsed outward, the third recess 176c is collapsed inward, and the fourth recess 176d and the fifth recess 176e are collapsed outward.

[0032] In some embodiments, other portions of the valve body 160 may include additional pressure-reducing portions to facilitate uniform collapse of the valve 110. For example, in some embodiments, the valve body 160 may include a pressure-reducing portion 170 disposed adjacent to a mating portion 164 of the valve body 160. Similarly, in some embodiments, the valve body 160 may include a pressure-reducing portion 167 disposed adjacent to an end portion 166 of the valve body 160. As described above, the pressure-reducing portions 167, 170 may provide regions of reduced stiffness to facilitate collapse of the valve body 160 in a desired manner.

[0033] Furthermore, in some embodiments, the valve body 160 may be formed to have increased body stiffness compared to certain conventional valves. As described herein, the valve body 160 may include one or more features that increase the stiffness of the valve body 160. Additionally, in some embodiments, the valve body 160 may be formed of a material having increased, decreased, or otherwise different stiffness compared to certain conventional valves. The valve body 160 may be configured to provide a desired activation force and a desired restoring force.

[0034] Similarly, a notch or other discontinuous slit 118 is formed in valve 110. In the closed position of valve 110, no object is positioned in the slit 118 of valve 110, and the slit 118 is normally closed. For example, in the closed position of valve 110, the distal end 120 of the support 112 does not protrude through the slit 118.

[0035] refer to Figure 4 The longitudinal axis X1 represents an axis parallel to the main dimension extension of the connector assembly 100. The housing 102 of the connector assembly 100 includes dimensions such that when the housing 102 is coupled to the base 104 (e.g., Figure 3 As shown, housing 102 extends further along longitudinal axis X1 than strut 112 in the direction of arrow A1 along longitudinal axis X1. In other words, the distal end 120 of strut 112 is contained within housing 102 and does not protrude beyond fluid inlet 106 of housing 102. Furthermore, when no external force is acting on valve 110 and valve 110 is in the closed position, valve 110 includes a dimension 140 representing the length dimension of valve 110.

[0036] Figure 6 A partial cross-sectional view of a connector assembly 100 according to some aspects of this disclosure is shown, further illustrating a fluid delivery device 150 inserted into a fluid inlet 106 of a housing 102 and engaging a valve 110. The fluid inlet 106 of the housing 102 includes dimensions and shapes that allow the fluid delivery device 150 to enter the housing 102 through the fluid inlet 106 and engage the valve 110. From the perspective of the valve 110, an external force is applied by the fluid delivery device 150. The external force provided by the fluid delivery device 150 causes displacement of the valve 110. For example, as... Figure 6 As shown, based on the external force applied by the fluid delivery device 150, the valve 110 is compressed or reduced to size 144 (less than). Figure 4 (Dimension 140 shown). In addition, the compression of valve 110 refers to the relative movement of valve 110 with respect to housing 102, base 104 and support 112.

[0037] In the depicted example, the fluid delivery device 150 may engage with a mating portion 164 of the valve 110 to move or displace the valve body 160. In some embodiments, the fluid delivery device 150 may include features that engage with the mating portion 164 to prevent or limit outward radial movement of the valve body 160, thereby minimizing undesirable folding or jamming of the valve 110.

[0038] refer to Figure 6Based on the displacement of valve 110, valve 110 is in the open position and can receive fluid from fluid delivery device 150. Several arrows are shown in connector assembly 100 and fluid delivery device 150. The arrows indicate fluid flow from fluid delivery device 150 and through connector assembly 100. Additionally, as... Figure 6 As shown, the downstream direction of fluid flow is illustrated. In the open position of valve 110, the distal end 120 of the support 112 protrudes through the slit 118 of valve 110. Furthermore, displacement of valve 110 exposes the opening 114 of the support 112. For illustrative purposes, Figure 6 The support 112 is rotated to make the opening 114 visible. When the opening 114 is not covered by the valve 10, fluid flows from the fluid delivery device 150 through the slit 118 (now open) and then flows into the lumen 116 by means of the opening 114. Thus, the slit 118 is fluidly connected to the opening 114 and the lumen 116.

[0039] Due to the displacement of valve 110, a fluid recess 124 is formed in valve 110. The fluid recess 124 represents a volume, i.e., a three-dimensional cavity or recess in valve 110. In some embodiments, during fluid delivery provided by the fluid delivery device 150, the fluid recess 124 receives at least some fluid. The volume of the fluid recess 124 depends on the amount of displacement of valve 110 caused by external pressure from the fluid delivery device 150 and can vary, as described below.

[0040] Figure 7 A partial cross-sectional view of the connector assembly is shown, with the valve in a collapsed position. Based on the increased insertion into the fluid inlet 106 of the housing 102, the fluid delivery device 150 applies additional external force to the valve 110, causing further displacement of the valve 110. For example, the valve 110 is further compressed within the housing 102, causing the distal end 120 of the strut 112 to protrude further through the slit 118 of the valve 110.

[0041] As described herein, valve 110 may have features, geometry, or otherwise be configured to collapse into a reduced size 144 in a consistent and uniform manner to avoid folding or otherwise jamming. Figure 7 As shown, portions of valve body 160 can be configured to uniformly collapse radially outward during operation (i.e., compression), while other portions of valve body 160 can be configured to uniformly collapse radially inward during operation, allowing valve 110 to collapse and recover during operation.

[0042] As shown, a portion of the valve body 160 including a first recess 176a and a second recess 176b can be radially outwardly collapsed relative to the support 112. As described herein, a first pressure-reducing portion 174a can further facilitate this radially outward collapse of this portion of the valve body 160. In some embodiments, a portion of the valve body 160 including a third recess 176c can be radially inwardly collapsed relative to the support 112. Similarly, portions of the valve body 160 including a fourth recess 176d and a fifth recess 176e can be radially outwardly collapsed relative to the support 112. As described herein, a second pressure-reducing portion 174b can further facilitate this radially outward collapse of this portion of the valve body 160. In the example shown, the valve 110 can be uniformly collapsed into the illustrated “2-1-2” configuration to allow for uniform collapse and recovery of the valve 110.

[0043] In some embodiments, other portions of the valve body 160 may collapse and recover in a consistent manner. For example, the mating portion 164 of the valve body 160 may collapse radially outward relative to the support 112. The pressure-reducing portion 170 may facilitate the radial outward collapse of the mating portion 164. Similarly, the end portion 166 of the valve body 160 may collapse radially outward relative to the support 112. The pressure-reducing portion 167 may facilitate the radial outward collapse of the end portion 166.

[0044] As the fluid delivery device 150 (previously shown) is removed from the housing 102, the valve 110 begins to depressurize. For example, the distal end 120 of the support 112 no longer protrudes through the slit 118 of the valve 110, and the valve 110 returns to the closed position. Therefore, the valve 110 prevents fluid (outside the valve 110) from subsequently entering the valve 110. Thus, the valve 110 covers the opening 114 and the distal end 120 of the support 112. When the fluid delivery device 150 is removed from the fluid inlet 106 of the housing 102 and no longer engages the valve 110, the valve 110 no longer shifts and returns to its original shape (as shown). Figure 3 and Figure 4 (As shown). Although not shown, valve 110 may cover opening 114 before fluid delivery device 150 is completely removed from fluid inlet 106 of housing 102 and before fluid delivery device 150 is completely disengaged from valve 110. As described herein, the features, geometry and / or configuration of valve 110 allow valve 110 to return to its original shape without jamming or requiring intervention.

[0045] Although this disclosure includes embodiments in which the pillar in the drawings comprises a single opening, it should be understood that the pillar may include any number of openings, each of which may receive fluid from a fluid delivery device.

[0046] The features of this disclosure provide a plurality of housings that can be coupled together to form a fluid passage therebetween. When coupled together, the features of this disclosure prevent unintentional separation between the housings.

For example, the phrase "an aspect" may refer to one or more aspects, and vice versa. Similarly, phrases like "embodiment" do not imply that such an embodiment is essential to the present subject matter, or that such an embodiment applies to all configurations of the present subject matter. Disclosure relating to an embodiment may apply to all embodiments or one or more embodiments. An embodiment may provide one or more examples. For example, the phrase "an embodiment" may refer to one or more embodiments, and vice versa. Similarly, phrases like "configuration" do not imply that such a configuration is essential to the present subject matter, or that such a configuration applies to all configurations of the present subject matter. Disclosure relating to a configuration may apply to all configurations or one or more configurations. A configuration may provide one or more examples. The phrase "such configuration" may refer to one or more configurations, and vice versa.

[0075] In one respect, unless otherwise stated, all measurements, values, ratings, positions, sizes, dimensions, and other specifications set forth in this specification, including those in the appended claims, are approximate rather than precise. In another respect, they are intended to have a reasonable range consistent with the functions they pertain to and with the custom of the art to which they belong.

[0076] In one respect, the term "linkage" can refer to a direct connection. In another respect, the term "linkage" can refer to an indirect connection.

[0077] For example, the terms “top,” “bottom,” “front,” “rear,” etc., used in this disclosure should be understood to refer to any frame of reference rather than a general gravitational frame of reference. Therefore, the top surface, bottom surface, front surface, and rear surface can extend upward, downward, diagonally, or horizontally in a gravitational frame of reference.

[0078] Various items may be arranged differently (e.g., in different orders or divided in different ways) without departing from the scope of the subject matter. All structural and functional equivalents of the elements throughout the various aspects described in this disclosure are known to or will be known hereafter to those skilled in the art, and are expressly incorporated herein by reference and intended to be covered by the claims. Furthermore, regardless of whether such disclosure is expressly recited in the claims, the disclosure herein is not intended for the public. Pursuant to paragraph 6 of 35 USC §112, elements of a claim will not be interpreted unless the element is clearly stated using the phrase “means”, or, in the case of a method claim, using the phrase “for the step of…”. Furthermore, the scope of terms such as “comprising,” “having,” etc., is intended to be inclusive in a manner similar to the term “comprising,” as interpreted when “comprising” is used as a transitional term in a claim.

[0079] The title, background art, utility model description, description of drawings, and abstract of this disclosure are incorporated herein and are provided as illustrative examples rather than limiting descriptions. This application is filed on the understanding that they are not intended to limit the scope or meaning of the claims. Furthermore, in the detailed description, it will be apparent that the description provides illustrative examples, and various features are combined in various embodiments to simplify the disclosure. This disclosure approach should not be construed as reflecting an intention that the claimed subject matter requires more features than expressly stated in each claim. Rather, as reflected in the appended claims, the utility model subject matter lies in all features of fewer than those in a single disclosure configuration or operation. The appended claims are therefore incorporated into the detailed description, each claim being an independent, separately claimed subject matter.

[0080] The claims are not intended to be limited to the aspects described herein, but rather to conform to the full scope consistent with the language claims and to include all legal equivalents. Nevertheless, none of the claims are intended to include subject matter that fails to satisfy the requirements of 35 U.S.SC § 101, 102, or 103, nor should they be interpreted in this manner.
