Description

Technical Field

[0001] This application relates to intravenous (IV) administration sets and devices used to administer fluid to a patient's vascular system through a needle or catheter inserted into a vein. More specifically, this application relates to a fluid connector cap that can be used to cover a fluid connector, to enable fluid priming, and to prevent contamination of the fluid connector and the IV administration set.

Background Art

[0002] An IV administration set is a device used to administer fluid from a container to a patient's vascular system through a needle or catheter inserted into a vein. An IV administration set can include a needle or Luer connector, an IV line or tubing, a flow regulator, a drip chamber, an injection line filter, a stopcock or valve for the intravenous set, a connector between parts of the set, an access port or injection site, a clamp such as a roller clamp, and an IV spike for connecting through the tubing to an IV bag or other infusion fluid container.

Summary of the Invention

[0003] To prevent air embolism, an IV administration set must be primed with fluid or an IV solution to remove air from the tubing before attaching the IV tubing to the patient. Air embolism is a potential complication of IV therapy and can enter the patient's blood system through unprimed IV tubing, damaged or cut tubing, access ports, and drip chambers with too little fluid.

[0004] To prime the IV administration set, the clamp is positioned along the IV line below the drip chamber and the clamp is moved to the closed position. If present, the protective cover over the IV spike is removed and the IV spike is inserted into the infusion fluid container. The infusion fluid container is normally suspended or hung from an IV pole. The drip chamber is compressed or squeezed to expel infusion fluid into the drip chamber and partially fill the drip chamber with the infusion fluid.

[0005] The clamp is moved to the open position to allow the infusion fluid and gas or air to move through the IV line to the distal end of the IV line (e.g., and the infusion fluid container). If a cap is fixed to the distal end of the IV line (or the fluid connector at the distal end of the IV line), the cap is removed to allow the fluid and gas to exit the IV administration set.

[0006] To dispose of the infusion fluid drained from the IV line during priming, the distal end of the IV line can be held by the caregiver above a sink or basin. The infusion fluid is allowed to drip from the distal end of the tubing until no large air bubbles are present in the intravascular administration set. During priming of the IV administration set, the caregiver can also hold the distal end of the tubing in an inverted position while the infusion fluid is moving toward the distal end of the tubing and until no air bubbles remain in the tubing. After the IV administration set has been primed, the distal end of the tubing, or the fluid connector fixed thereto, must be covered to prevent contamination of the IV administration set.

[0007] Priming of the IV administration set may require the caregiver to hold the distal end of the tubing in an inverted position for 10 - 30 seconds. This process of priming the IV administration set may be repeated multiple times for each shift and for multiple patients, interfering with the caregiver's ability to pay attention to other tasks, increasing the potential for errors such as contamination of the IV administration set, worsening the physical movements required, which can cause injury to the caregiver.

[0008] During preparation and priming, if the cap is removed from the distal end of the IV line or the fluid connector and the distal end of the IV line or the fluid connector touches the floor or another object, the IV administration set may become contaminated. Also, the cap removed from the distal end of the IV line or the fluid connector may become contaminated while being removed and then, if reattached to the distal end of the IV line or the fluid connector of the IV administration set, the IV administration set may also become contaminated.

[0009] Priming of the IV administration set can cause the caregiver to be exposed to the intravenous fluid being drained from the tubing. For example, exposure or contact with the intravenous fluid can be harmful to the caregiver, such as when the intravenous fluid is a toxic chemotherapeutic drug for use in oncology. The harm from exposure can occur from a single exposure to the intravenous fluid or from repeated exposures.

[0010] According to at least some embodiments, a predetermined procedure can be implemented to prevent contamination of the IV administration set, but it is recognized herein that certain problems occur when countless IV administration sets are implemented during medical procedures. For example, the IV administration set may become contaminated and the contamination can be transferred to the patient when the IV administration set is primed and connected to the patient's intravascular system.

[0011] Some embodiments disclosed herein relate to the recognition that a caregiver may implement a virtually endless number of IV administration sets, which may physically fatigue the caregiver due to repeated preparation and priming of the IV administration sets. The embodiments disclosed herein also relate to the recognition that a caregiver may be at risk of injury from exposure to the infusion fluid.

[0012] According to at least some embodiments disclosed herein, the present disclosure provides an IV priming cap that can prevent contamination of an IV administration set, facilitate physical movement by a caregiver, reduce the time used by a caregiver for preparation and priming of an IV administration, and prevent harm to the caregiver from exposure to the infusion fluid.

[0017] It will become more readily apparent to those skilled in the art from the present disclosure that various configurations of the subject technology, and it is understood that the various configurations of the subject technology are shown and described as illustrations. As will be recognized, the subject technology is capable of other configurations and different configurations, and some of its details are capable of modification in various other respects without departing from the scope of the subject technology. Accordingly, the summary, drawings, and detailed description should be regarded as being essentially for illustrative purposes and not as being limiting.

[0018] The detailed description set forth below is intended as a description of various configurations of the subject technology and is not intended to represent the only configuration in which the subject technology may be practiced. The accompanying drawings are incorporated herein and constitute a part of the detailed description. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject technology. However, it will become apparent to those skilled in the art that the subject technology may be practiced without these specific details. In some instances, well-known structures and components are shown in block diagram form to avoid obscuring the concepts of the subject technology. Similar components are labeled with the same element numbers for ease of understanding.

[0019] According to at least some embodiments, disclosed herein is an IV priming cap capable of preventing contamination of an IV administration set, including preventing contamination that can occur during the preparation of the IV administration set and the patient, during priming of the IV administration set, and during connection of the IV administration set to the patient.

[0020] Figure 1 illustrates caregiver 10 and patient 12. The patient is receiving an infusion fluid through an IV administration set 20 connected to the patient's vasculature. Figure 2 illustrates an infusion fluid container 22 and an IV administration set 20. The IV administration set includes a drip chamber 24 connected to the infusion fluid container 22, tubing of an IV line 26 with its proximal end connected to the drip chamber 24, and a distal end of the IV line 26 connected to a fluid connector 28. A roller clamp 30 is connected to a predetermined length of the IV line 26 between the drip chamber 24 and the fluid connector 28. The fluid connector is connected to an IV priming cap 34, and the IV priming cap 34 is connected to a predetermined length of the IV line 26 between the drip chamber 24 and the roller clamp 30. In some embodiments, the IV priming cap 34 engages or connects with another part of the IV administration set (such as a roller clamp 30 or an IV line pinch clamp) and is capable of suspending the distal end of the IV line and the fluid connector from the IV administration set.

[0021] The IV priming cap is configured such that when the IV priming cap is connected to the IV administration set, the distal end of the IV line and the fluid connector are inverted relative to the orientation of the proximal end of the IV line. The inverted orientation of the distal end of the IV line and the fluid connector facilitates priming of the IV administration set.

[0022] The IV priming cap can be connected to the IV administration set using a coupling tab extending from the IV priming cap. The coupling tab can be configured to include one or more arms that form either a tubing passage or a slot.

[0023] The tubing passageway and / or slot can include a width that enables the IV priming cap to be connected to a predetermined length of IV tubing without compressing the IV line so that the velocity of fluid flow therethrough is not reduced. However, in some embodiments, the tubing passageway and / or slot can include a predetermined width that causes a predetermined length of IV line to be compressed, thereby causing the velocity of fluid flow therethrough to be reduced.

[0024] In some aspects of the present disclosure, a predetermined length of IV line is compressed by an IV priming cap such that the velocity of fluid flow through the IV line is enabled to prime the IV administration set, however, the velocity of the fluid flow through the IV line is not sufficient to administer the infusion fluid to the patient. As a result, a caregiver can prime the IV administration set with the IV priming cap attached to the IV line, however, the caregiver cannot achieve the desired flow rate for treatment. Since the desired flow rate is not achieved, the caregiver is prompted to remove and / or discard the IV priming cap before administering the infusion fluid to the patient.

[0025] The IV administration set can be primed by the distal end of an IV line having a fluid connector connected to the IV priming cap, or the IV administration set can be primed by separating the fluid connector from the IV priming cap. The IV priming cap can be separated from the IV administration set and disposed of before or after priming the IV administration set.

[0026] In some embodiments of the present disclosure, an IV priming cap can provide an indication of priming, including an indication that priming has occurred. For example, the IV priming cap can include a material that changes color to indicate that fluid has been discharged from the IV administration set. In some embodiments, the IV priming cap includes a hydrophobic filter that can change color to indicate contact with a liquid. Also, the IV priming cap can provide an indication that the IV priming cap remains connected to the IV administration set. For example, the IV priming cap can be configured to restrict fluid flow through the IV line as an indication to remove the IV priming cap.

[0027] The present disclosure describes embodiments of an IV priming cap that can connect to a male luer type fluid connector, but it should be recognized that the IV priming cap can be connected to other fluid connectors. However, for clarity and brevity, the present disclosure will primarily refer to male luer fluid connectors. Additionally, the present disclosure describes an IV priming cap with respect to an IV administration set, but it should be recognized that the IV priming cap can be connected to other IV fluid delivery devices and systems. However, for clarity and brevity, the present disclosure will primarily refer to IV administration sets.

[0028] Figures 3A - 3E illustrate an embodiment of an IV priming cap 100. The IV priming cap can connect to the distal end of the IV line or to a fluid connector at the distal end of the IV line. In at least some embodiments disclosed herein, the IV priming cap can connect to a fluid connector and a portion of the IV administration set and suspend the distal end of the IV line and the fluid connector from the IV administration set.

[0029] The IV priming cap 100 includes a cover body portion 102 and a coupling tab 104. The cover body portion 102 includes a proximal end portion 106 and a distal end portion 108 opposite the proximal end portion 106. The cover body portion 102 includes an inner surface 110 that defines a cavity that extends into the cover body portion 102 and is configured to receive a fluid connector therein. The cavity can extend from the proximal end portion 106 to the distal end portion 108 of the cover body portion 102. A longitudinal connector cavity axis 1A extends between the proximal end portion 106 and the distal end portion 108 of the cover body portion 102.

[0030] The cover body portion 102 has an outer surface with a predetermined cross-sectional profile in a direction transverse to the longitudinal connector cavity axis 1A. As used in this disclosure, the term transverse direction can include any direction or angle that intersects or crosses or can extend at an angle to another direction. The cross-sectional profile of the cover body portion 102 can be tapered from the proximal end portion 106 to the distal end portion 108. In some embodiments of the present disclosure, the outer surface of the cover body portion 102 has a proximal segment 112 and a distal segment 114. The proximal segment 112 extends from the proximal end portion 106 to the distal end portion 108, and the distal segment 114 extends from the proximal segment 112 to the distal end portion 108. The proximal segment 112 has a first cross-sectional width, and the distal segment 114 has a second cross-sectional width that is smaller than the first cross-sectional width. In some embodiments, the outer surface of the cover body portion 102 is tapered between the proximal segment 112 and the distal segment 114.

[0031] The IV priming cap 100 can include a rib 116 that protrudes from the outer surface of the cover body 102, as shown in FIGS. 3A - 3C. The rib 116 can extend between the proximal end 106 and the distal end 108 of the cover body 102. In at least some of the embodiments disclosed herein, the rib 116 can extend along the distal segment 114 between the proximal segment 112 of the cover body and the distal end 108.

[0032] The rib 116 can provide an increased surface area and a levering action for gripping the IV priming cap 100 and for rotating the IV priming cap 100 about the longitudinal connector cavity axis 1A. Also, the rib 116 can provide structural rigidity and support along the proximal segment 112 and the distal segment 114.

[0033] In some embodiments, the outer surface of the cover body 102 can include a groove or channel that extends into the outer surface of the cover body 102. In at least some of the embodiments of the present disclosure, the outer surface of the cover body 102 can include concave portions (e.g., dimples or notches), convex portions (e.g., bulges or ridges), or any combination thereof. Both concave and convex surface features can increase the surface area of the outer surface area and increase the rigidity of the cover body 102.

[0034] The inner surface 110 of the cover body can form a proximal cavity 120 along the proximal segment 112 of the cover body, and can also form a distal cavity 122 along the distal segment 114 of the cover body, as best illustrated in FIG. 3E.

[0035] When the IV priming cap 100 is connected to a fluid connector, different portions of the fluid connector can engage the cover body portion 102 in the proximal cavity 120 and the distal cavity 122. In some examples, when a male luer connector is connected to the IV priming cap 100, the body portion of the fluid connector can be positioned within the proximal cavity 120 and the male luer portion of the fluid connector can be positioned within the distal cavity 122. In an example, the outer surface of a fluid connector having threads or other coupling features can engage the inner surface 110 of the cover body portion along the proximal cavity 120. When the coupling feature of the fluid connector is engaged with the inner surface 110 of the cover body portion along the proximal cavity 120, the male luer portion of the fluid connector can engage the inner surface 110 of the cover body portion along the distal cavity 122.

[0036] The cover body portion 102 can include a wall portion 124 that can extend from the distal segment 114 into the proximal cavity 120 and about the connector cavity axis 1A. The inner surface of the wall portion 124 can form a portion of the distal cavity 122. The outer surface of the wall portion 124 is spaced from the inner surface 110 of the cover body portion along the proximal segment 112.

[0037] The distal cavity 122 has a cross-sectional width formed between the inner surface of the distal cavity 122 and the wall portion 124. The cross-sectional width of the distal cavity 122 can be configured to engage with the male Luer of a fluid connector inserted into the cavity of the cover body portion 102. The cross-sectional width of the distal cavity 122 can be tapered toward the distal end 108 of the cover body portion. In some aspects of the present disclosure, the IV priming cap 100 can fluidly seal against the male Luer of the fluid connector by forming an interference fit between the male Luer and the inner surface of the cover body portion 102 along the distal cavity 122.

[0038] The cover body portion 102 includes a priming passage 126 and can allow fluid movement between the cavity of the cover body portion 102 and the area adjacent to the outer surface of the IV priming cap 100. The priming passage 126 extends between the distal cavity 122 and the distal end 108 of the cover body portion. In some embodiments, the priming passage 126 can extend from either the proximal cavity 120 and / or the distal cavity 120 to the outer surface of the cover body portion 102. In some examples, the priming passage 126 extends between the distal cavity 120 and the outer side surface of the cover body portion along the distal segment 114. In some embodiments, at least a portion of the priming passage 126 can be formed by a groove extending into the cover body portion 102.

[0039] The priming passage 126 allows priming of the IV administration set without separating or removing the IV priming cap 100 from the fluid connector. As a result, the infusion fluid and gas can be directed out of the IV administration set through the fluid connector with the IV priming cap 100 secured thereto. Since the IV priming cap 100 does not need to be removed or separated from the fluid connector during priming, the possibility of contaminating the fluid connector or the IV administration set is reduced.

[0040] In at least some embodiments disclosed herein, the IV priming cap 100 includes a filter 128. The filter 128 is positioned along the priming passage 126 and filters or separates the fluid moving therethrough. In some embodiments of the present disclosure, the filter 128 can provide an indication that the IV administration set has been used and / or primed.

[0041] The filter 128 can be positioned within the priming passage 126 or can be coupled to the distal portion of the cover body 102. Referring to FIG. 3E, the IV priming cap includes a recess 130 into which the filter 128 can be received. The recess 130 can extend into the distal end of the cover body 102, and the priming passage 126 intersects the recess 130. In some embodiments, the IV priming cap does not include a filter. In embodiments without a filter, the priming passage can extend through the recess 130 (e.g., FIG. 4E).

[0042] The filter 128 is configured to allow gas to move through the filter while resisting the movement of liquid through the filter. For example, the filter 128 can be a hydrophobic filter. In some examples, the filter 128 includes a membrane comprising a polyethylene material or coated with polyethylene.

[0043] To provide an indication that the IV administration set has been used and / or primed, the filter can include a changing color. For example, the filter can change color when a liquid (e.g., the infusion fluid) contacts the filter.

[0044] In at least some embodiments disclosed herein, the inner surface of the cover body portion 102 includes a ridge 134 configured to engage a fluid connector positioned within the cavity of the IV priming cap. The ridge 134 can be formed as either a helical ridge or a longitudinal ridge. In some embodiments, the ridge 134 can be of any shape configured to engage the fluid connector.

[0045] A helical ridge (e.g., FIGS. 3B and 3E) can be shaped as a thread along the inner surface of the cover body portion. The thread can extend away from the inner surface of the cover body portion or into the inner surface 110. The thread can have a thread pitch configured to engage the thread of a fluid connector connected to the IV priming cap.

[0046] A longitudinal ridge (e.g., FIGS. 4B and 4E) can be shaped as either a wall portion extending longitudinally along the inner surface of the cover body portion or a groove or channel extending into the inner surface 110 of the cover body portion. In some aspects, the ridge can be formed between channels extending into the inner surface 110 of the cover body portion. The longitudinal ridge can be configured to engage the outer surface of a fluid connector connected to the IV priming cap.

[0047] In some embodiments of the present disclosure, either the helical or longitudinal ridge can be shaped as a plurality of protrusions in a helical or angled pattern relative to the connector cavity axis A1 and can extend parallel to the connector cavity axis A1.

[0048] The cover body portion 102 can include a protrusion 138 that extends into either the proximal cavity 120 or the distal cavity 124. The protrusion 138 can extend from the inner surface 110 of the cover body portion into the proximal cavity 120. In FIGS. 3D and 3E, the protrusion 138 extends from the inner surface 110 between the proximal segment 112 and the distal segment 114 of the cover body portion. In some embodiments, the protrusions 138 are spaced apart around the connector cavity axis A1.

[0049] The protrusion 138 can resist the movement of the fluid connector in the proximal cavity 120 in the direction toward the distal cavity 122. In some aspects, the protrusion 138 can provide rigidity between the proximal segment 112 and the distal segment 114 of the cover body portion.

[0050] The coupling tab 104 of the IV priming cap 100 is generally shaped as a clamp that extends from the cover body portion 102 and engages or connects with a portion of the IV administration set. When the coupling tab 104 is connected to the IV administration set, the distal end of the IV line and the fluid connector held within the IV priming cap are covered to resist contamination from contact by a caregiver or patient. Further, the distal end of the IV line and the fluid connector are suspended from the IV administration set to prevent contamination from contact with the floor or ground. Further, the inverted orientation of the distal end of the IV line and the fluid connector facilitates priming of the IV administration set when the IV priming cap is connected to the IV administration set.

[0051] The coupling tab 104 is shaped as a clamp having a first coupling arm 140 and a second coupling arm 142. Each of the first coupling arm 140 and the second coupling arm 142 includes a base portion connected to the cover body portion 102 and a tip portion distal to the cover body portion 102. The coupling tab 104 extends away from the cover body portion 102 in a direction transverse to the connector cavity axis 1A.

[0052] Each of the first coupling arm 140 and the second coupling arm 142 includes an inner surface 144 facing the other of the first coupling arm 140 and the second coupling arm 142. The inner surfaces of the first coupling arm 140 and the second coupling arm 142 form a tubing passage 146 therebetween, which is generally identified by the area within the dashed lines of FIG. 3D.

[0053] Also, the inner surfaces of the first coupling arm 140 and the second coupling arm 142 form at least a portion of a slot 148, which is generally identified by the area within the dashed lines of FIG. 3D. The slot 148 extends between the tubing passage 146 and the outer surface of the coupling tab 104 and enables a predetermined length of IV line to be moved into the tubing passage 146. Also, the slot 148 can enable the coupling tab 104 to be connected to another structure. In some embodiments, the slot extends from the tip portion to the base portion of the coupling tab 104.

[0054] A portion of the inner surfaces of the first coupling arm 140 and the second coupling arm 142 along the slot 148 extends inwardly such that the length L1 between the inner surfaces 144 along the slot 148 is less than the length L2 between the inner surfaces 144 along the tubing passage 146. The length L1 can be approximately equal to or less than the diameter of the IV line. In use, the first coupling arm 140 and the second coupling arm 142 can be biased away from each other, allowing a predetermined length of IV tubing to be moved through the slot into the tubing passage 146.

[0055] The longitudinal tubing passage axis 1B extends through the tubing passage 146 and is parallel to the longitudinal connector cavity axis 1A. When the coupling tab 104 is connected to a predetermined length of IV line, the predetermined length of IV line will generally be aligned and extend along the longitudinal tubing passage axis 1B, and the distal end portion of the IV line will generally be aligned along the longitudinal connector cavity axis 1A. In some embodiments, the longitudinal tubing passage axis 1B extends at a predetermined angle transverse to the connector cavity axis 1A, where the transverse direction includes any angle that extends across the connector cavity axis 1A.

[0056] In some embodiments of the present disclosure, the IV priming cap 200 includes a coupling tab 204 having opposing coupling arms, as illustrated in FIGS. 4A-4E.

[0057] The IV priming cap 200 can include features similar to those described with reference to the IV priming cap 100 (Figs. 3A-3E). As such, the description of some of the similar features is not repeated herein for clarity and brevity. However, the features described with reference to embodiments of the present disclosure can be implemented by any embodiment of the present disclosure.

[0058] The IV priming cap 200 includes a cover body portion 202 and a coupling tab 204. The cover body portion 202 includes a proximal end portion 206 and a distal end portion 208, with the distal end portion 208 being on the opposite side of the proximal end portion 206. The cover body portion 202 includes an inner surface 210 that defines a cavity that extends into the cover body portion 202 and is configured to receive a fluid connector therein. A longitudinal connector cavity axis 2A extends between the proximal end portion 206 and the distal end portion 208 of the cover body portion 202.

[0059] The inner surface 210 includes a ridge 234 that is configured to engage a fluid connector positioned within the cavity of the IV priming cap. The ridge 234 is shaped as a longitudinal ridge that can create an interference fit between the IV priming cap 200 and the fluid connector inserted into the cavity. In some aspects, the ridge 234 is configured to mate or engage with a slot of the fluid connector.

[0060] The ridge 234 extends between the proximal end 206 and the distal end 208 of the cover body portion 202 and is aligned with the connector cavity axis 2A. Each of the ridges 234 extends parallel to the connector cavity axis 2A. However, in some embodiments, the ridge 234 can extend in a direction transverse to the connector cavity axis 2A. For example, the ridge 234 can extend in a direction transverse to the connector cavity axis 2A and form a spiral of the ridge along the inner surface.

[0061] The ridges 234 can be spaced apart from each other along the inner surface of the cover body portion 202. The ridges 234 are spaced apart with an equal distance between the longitudinal ridges 234. However, in some embodiments, the longitudinal ridges 234 can be spaced apart with different distances between one or more of the ridges. The ridges 234 having different distances between them can enable a fluid connector having a fitting channel with similar spacing between them to be inserted into the IV priming cap.

[0062] The ridges 234 include a predetermined height between the inner surface of the cover body portion and the innermost surface of each ridge 234 (for example, the surface closest to the connector cavity axis 2A). One or more of the ridges 234 can have a different height relative to another longitudinal ridge 234.

[0063] Referring to FIG. 4D, the IV priming cap 200 can have a ridge 234A having a first height H1 and a ridge 234B having a second height H2, and the second height H2 is greater than the first height H1. The ridges can be positioned such that the ridge 234A having the first height H1 is positioned between the ridges 234B having the second height H2.

[0064] In some embodiments of the present disclosure, the ridge 234 can have a height that increases or decreases between the proximal end 206 and the distal end 208. For example, the height of the ridge 234 illustrated in FIG. 4E decreases from the proximal end 206 toward the distal end 208, and the cross-sectional length between the inner surfaces of the ridge is tapered away from the proximal end 206.

[0065] The coupling tab 204 of the IV priming cap 200 extends away from the cover body portion 202 in a direction transverse to the connector cavity axis 2A. The coupling tab 204 has a first coupling arm 240 and a second coupling arm 242, and the second coupling arm 242 is oriented on the opposite side of the first coupling arm 240 to form a lobster claw shape.

[0066] Each of the first coupling arm 240 and the second coupling arm 242 includes a base portion connected to the cover body portion 202 and a tip portion distal to the partial cover body portion 202. The first coupling arm 240 and the second coupling arm 242 have a predetermined width in a direction transverse to the connector cavity axis 2A. The width of each of the first coupling arm 240 and the second coupling arm 242 is tapered from the base portion toward the tip portion.

[0067] The base portions of the first coupling arm 240 and the second coupling arm 242 extend along the outer surface of the cover body portion 202 over an angle 2C around the connector cavity axis 2A. In some embodiments of the present disclosure, the angle 2C is at least about 90 degrees and / or is about 180 degrees or less. In some embodiments, the base portion extends along the outer surface of the cover body portion 202 over an angle of about 140 degrees around the connector cavity axis 2A.

[0068] The first coupling arm 240 and the second coupling arm 242 include an inner surface 244 that faces the other of the first coupling arm 240 and the second coupling arm 242. The inner surfaces of the first coupling arm 240 and the second coupling arm 242 form a tubing passage 246, which is generally identified by the area within the dashed line of FIG. 4D. A longitudinal tubing passage axis 2B extends through the tubing passage 246. The longitudinal tubing passage axis 2B extends at a predetermined angle parallel to the longitudinal connector cavity axis 2A. In some embodiments, the tubing passage axis 2B extends at a predetermined angle transverse to the longitudinal connector cavity axis 2A. The tubing passage 246 has a cross-sectional shape. The cross-sectional shape can be any of circular, elliptical, semi-circular, and polygonal. In some embodiments, the tubing passage 246 has a diameter smaller than the diameter of the IV line, and the coupling tab 200 engages the IV line and resists movement between the IV priming cap 200 and the IV line.

[0069] Also, the inner surfaces of the first coupling arm 240 and the second coupling arm 242 form at least a portion of a slot 248, which is generally identified by the area within the dashed line of FIG. 4D. The slot 248 extends between the tubing passage 246 and the outer surface of the coupling tab 204. The slot 248 is positioned such that a passage is formed by the slot 248 between the tubing passage 246 and the outer surface of the coupling tab 204. The slot 248 can extend from the tip portions of the first and second coupling arms 240 and 242 toward the base portion.

[0070] A portion of the inner surfaces of the first coupling arm 240 and the second coupling arm 242 along the slot 248 extends inwardly, and the length between the inner surfaces 244 along the slot 248 is smaller than the length between the inner surfaces 244 along the tubing passage 246.

[0071] The first coupling arm 240 and the second coupling arm 242 include a proximal surface facing the direction of the proximal end 206 and a distal surface facing the direction of the distal end 208. The distal surface includes a recessed surface 250, and at least a portion of the peripheral portion of each coupling arm 240 and 242 includes a wall portion 252 extending above the recessed surface 250. In some embodiments of the present disclosure, either the proximal surface or the distal surface of the coupling arms 240 and 242 can include a recessed surface. The recessed surface 250 and the wall portion 252 provide structural rigidity while reducing the amount of material required to form the coupling tab 204.

[0072] The tubing passage 246 and the slot 248 allow a predetermined length of IV line to be moved into the tubing passage 246. Also, the tubing passage 246 and the slot 248 can allow the IV priming cap 200 to be connected to another structure (such as a pole or a clamp). When the coupling tab 204 is connected by a predetermined length of IV line, the predetermined length of IV line will generally extend aligned along the longitudinal tubing passage axis 2B, and the distal end portion of the IV line will generally be aligned along the longitudinal connector cavity axis 2A.

[0073] In some embodiments of the present disclosure, the IV priming cap 300 includes a hook-shaped coupling tab 304 as illustrated in FIGS. 5A - 5D.

[0074] The IV priming cap 300 can include features similar to those described with reference to other embodiments disclosed herein. As such, descriptions of some of the similar features are not repeated herein for clarity and brevity.

[0075] The IV priming cap 300 includes a cover body portion 302 and a coupling tab 304. The cover body portion 302 includes a proximal end portion 306 and a distal end portion 308, and the distal end portion 308 is on the opposite side of the proximal end portion 306. The cover body portion 302 includes an inner surface 310 that defines a cavity that extends into the cover body portion 302 and is configured to receive a fluid connector therein. A longitudinal connector cavity axis 3A extends between the proximal end portion 306 and the distal end portion 308 of the cover body portion 302.

[0076] The coupling tab 304 of the IV priming cap 300 extends away from the cover body portion 302 in a direction transverse to the connector cavity axis 3A. The coupling tab includes a base portion that is connected to the cover body portion 302 and a tip portion that is distal to the cover body portion 302.

[0077] The base portion extends from the cover body portion 302 in a first direction, and the tip portion extends from the base portion in a second direction, where the second direction is different from the first direction. The first direction is transverse to the connector cavity axis 3A and extends away from the outer surface of the cover body portion 302. Also, the second direction is transverse to the connector cavity axis 3A but extends toward the outer surface of the cover body portion 302. Together, the base portion and the tip portion form a hook-shaped coupling tab 304, and the hook-shaped coupling tab 304 has an inner surface that forms a tubing passage 346, with the longitudinal tubing passage axis 3B passing through the tubing passage 346. The tubing passage axis 3B is parallel to the longitudinal connector cavity axis 3A. In some embodiments, the tubing passage axis 3B extends at a predetermined angle transverse to the connector cavity axis 3A.

[0078] In some embodiments, the tubing passage 346 has a diameter smaller than the diameter of the IV line, and the coupling tab 304 engages the IV line and resists movement between the IV priming cap 300 and the IV line.

[0079] At least a portion of the slot 348 can be formed between the coupling tab 304 and the cover body portion 302. More specifically, the slot 348 can be formed between the tip portion of the coupling tab 302 and the outer surface of the cover body portion 304. In some embodiments, the slot 348 extends between the tubing passage 346 and the outer surface of the coupling tab 304. The slot 348 is oriented to extend in a direction toward the base portion of the coupling tab 304 between the tubing passage 346 and the outer surface of the coupling tab 304.

[0080] The cross-section of the coupling tab 304 is shaped as a wall portion having a height and a width. The height of the coupling tab 304 extends between a proximal surface (facing the direction of the proximal end 306) and a distal surface (facing the direction of the distal end 308). Along the base portion of the coupling tab 304, the wall height decreases away from the cover body portion 302 from a first height H3 to a second height H4. Along the tip portion of the coupling tab 304, the wall height increases toward the cover body portion 302 from the second height H4 to a third height H5. The third height H5 is greater than the second height H4. In some embodiments, the third height H5 is between the first height H3 and the second height H4.

[0081] The width of the coupling tab 304 is smaller than the first height H3, the second height H4, and the third height H5. With respect to the height, the narrow width of the coupling tab 304 allows the coupling tab 304 to be biased away from the tubing passage axis 3B when a predetermined length of IV line is moved through the slot 346 into the tubing passage 348. With respect to the width, the high height of the coupling tab 304 provides a large inner surface area of the coupling tab 304 for engaging a predetermined length of IV line inserted into the tubing passage 348. The engagement of the inner surface of the coupling tab 304 resists the sliding or movement of the IV line relative to the IV priming cap 300.

[0082] The distal portion of the coupling tab 304 can include a protrusion 360, which has an outer surface that extends away from the outer surface of the coupling tab 304. The protrusion 360 can be shaped into a cylindrical shape and can extend longitudinally along the height of the coupling tab 304. In some embodiments, the protrusion 360 can include a cross-sectional shape including any of a circle, an ellipse, a semi-circle, and a polygon. The cross-sectional profile of the protrusion 360 (in a direction transverse to the tubing passage axis 3B) includes a width that is tapered along the height of the coupling tab 304. The width of the protrusion 360 is tapered from the proximal end of the coupling tab towards the distal end of the coupling tab 304.

[0083] The tubing passage 346 and the slot 348 allow a predetermined length of IV line to be moved into the tubing passage 346. Also, the tubing passage 346 and the slot 348 can also allow the IV priming cap 300 to be connected to another structure (such as a pole or a clamp, etc.). When the coupling tab 304 is connected by a predetermined length of IV line, the predetermined length of IV line generally extends aligned along the longitudinal tubing passage axis 3B, and the distal end portion of the IV line is generally aligned along the longitudinal connector cavity axis 3A.

[0084] Referring to FIGS. 6A - 6D, an embodiment of an IV priming cap 400 having a hook-shaped coupling tab 404 is illustrated. The IV priming cap 400 can include features similar to those described with reference to other embodiments disclosed herein. As such, descriptions of some of the similar features are not repeated herein for clarity and brevity.

[0085] The IV priming cap 400 includes a cover body portion 402 and a coupling tab 404. The cover body portion 402 includes a proximal end portion 406 and a distal end portion 408, and the distal end portion 408 is on the opposite side of the proximal end portion 406. The inner surface 410 of the cover body portion 402 defines a cavity that extends into the cover body portion 402 and is configured to receive a fluid connector therein. A longitudinal connector cavity axis 4A extends between the proximal end portion 406 and the distal end portion 408 of the cover body portion 402.

[0086] The coupling tab 404 of the IV priming cap 400 extends away from the cover body portion 402 in a direction transverse to the connector cavity axis 4A. The coupling tab includes a base portion coupled to the cover body portion 402 and a tip portion distal to the cover body portion 402.

[0087] The base portion of the coupling tab 404 extends along the outer surface of the cover body portion 402 over an angle 4C about the connector cavity axis 2A. In some embodiments of the present disclosure, the angle 4C is at least about 10 degrees and / or is about 90 degrees or less. In some embodiments, the base portion extends along the outer surface of the cover body portion 402 over an angle of about 90 degrees about the connector cavity axis 4A.

[0088] The base portion extends from the cover body portion 402 in a first direction, and the tip portion extends from the base portion in a second direction, where the second direction is different from the first direction. The first direction is transverse to the connector cavity axis 4A and extends away from the outer surface of the cover body portion 402. Also, the second direction is transverse to the connector cavity axis 4A but extends toward the outer surface of the cover body portion 402. Together, the base portion and the tip portion form a hook-shaped coupling tab 404, and the hook-shaped coupling tab 404 has an inner surface that forms a tubing passage 446, with a longitudinal tubing passage axis 4B passing through the tubing passage 446. The tubing passage axis 4B is parallel to the longitudinal connector cavity axis 4A. In some embodiments, the tubing passage axis 4B extends at a predetermined angle transverse to the connector cavity axis 4A.

[0089] In some embodiments, the tubing passage 446 has a diameter smaller than the diameter of the IV line, and the coupling tab 404 engages the IV line and resists movement between the IV priming cap 400 and the IV line.

[0090] At least a portion of the slot 448 can be formed between the coupling tab 404 and the cover body portion 402. More specifically, the slot 448 can be formed between the tip portion of the coupling tab 404 and the outer surface of the cover body portion 402. The slot 448 extends between the tubing passage 446 and the outer surface of the coupling tab 404. In some embodiments, the slot 448 is oriented to extend between the tubing passage 446 and the outer surface of the coupling tab 404 in a direction toward the base portion of the coupling tab 404.

[0091] The coupling tab 404 is shaped as a wall portion having a predetermined height and width. The height of the coupling tab 404 extends between a proximal surface (facing the direction of the proximal end 406) and a distal surface (facing the direction of the distal end 408). Along the base portion of the coupling tab 404, the width decreases away from the cover body portion 402. In some embodiments, the width increases towards the cover body portion 402 along the tip portion of the coupling tab 404.

[0092] The distal surface includes a recessed surface 450, and at least a portion of the peripheral portion of the coupling tab 404 includes a wall portion 452 extending above the recessed surface 450. In some embodiments of the present disclosure, either the proximal surface or the distal surface of the coupling tab 404 can include a recessed surface. The recessed surface 450 and the wall portion 452 provide structural rigidity while reducing the amount of material required to form the coupling tab 404.

[0093] The tubing passage 446 and the slot 448 enable a predetermined length of IV line to be moved into the tubing passage 446. When a predetermined length of IV line is inserted through the slot 448 into the tubing passage 446, the rigidity of the coupling tab 404 resists deformation or biasing of the coupling tab 404 with respect to the IV line. When the tubing passage 446 has a cross-sectional length smaller than the diameter of the IV line, a predetermined length of IV line inserted into the tubing passage 446 is compressed.

[0094] The tubing passage 446 and slot 448 can also enable the IV priming cap 400 to be coupled to another structure (such as a pole or clamp). When the coupling tab 404 is coupled by an IV line of a predetermined length, the IV line of the predetermined length will generally be aligned and extend along the longitudinal tubing passage axis 4B, and the distal end portion of the IV line will generally be aligned along the longitudinal connector cavity axis 4A.

[0095] In some embodiments of the present disclosure, the IV priming cap 500 includes a clip-shaped coupling tab 504 as illustrated in FIGS. 7A-7D.

[0096] The IV priming cap 500 can include features similar to those described with reference to other embodiments disclosed herein. As such, the description of some of the similar features is not repeated herein for purposes of clarity and brevity.

[0097] The IV priming cap 500 includes a cover body portion 502 and a coupling tab 504. The cover body portion 502 includes a proximal end 506 and a distal end 508, and the distal end 508 is on the opposite side of the proximal end 506. The cover body portion 502 includes an inner surface 510 that defines a cavity that extends into the cover body portion 502 and is configured to receive a fluid connector therein. A longitudinal connector cavity axis 5A extends between the proximal end 506 and the distal end 508 of the cover body portion 502.

[0098] The coupling tab 504 of the IV priming cap 500 extends away from the cover body portion 502 in a direction transverse to the connector cavity axis 5A. The coupling tab includes a base portion 562 connected to the cover body portion 502, an intermediate portion 564 extending from the base portion and distal to the cover body portion 502, and a tip portion 566 extending from the intermediate portion.

[0099] The base portion 562 extends from the cover body portion 502 in a first direction that is transverse to the connector cavity axis 5A and extends away from the outer surface of the cover body portion 502. The intermediate portion 564 extends from the base portion 562 in a second direction that is different from the first direction. The tip portion 566 extends from the intermediate portion 564 in a third direction that is different from the first and second directions. In some embodiments, the third direction is also transverse to the connector cavity axis 5A but extends toward the outer surface of the cover body portion 502.

[0100] The base portion 562, the intermediate portion 564, and the tip portion 566 form a clip-shaped coupling tab 504 that has an inner surface forming the tubing passage 546 with the longitudinal tubing passage axis 5B passing through the tubing passage 546.

[0101] The second direction can be either parallel or transverse to the connector cavity axis 5A. In embodiments where the second direction is parallel to the connector cavity axis 5A, the tubing passage axis 5B is transverse to the connector cavity axis 5A. In embodiments where the second direction is transverse to the connector cavity axis 5A, the tubing passage axis 5B is parallel to the connector cavity axis 5A.

[0102] The distance between the outer surface of the cover body portion 502 and the inner surface of the intermediate portion 564 is smaller than the diameter of the IV line, and the coupling tab 500 engages with the IV line and resists movement between the IV priming cap 500 and the IV line.

[0103] At least a portion of the slot 548 can be formed between the coupling tab 504 and the cover body portion 502. More specifically, the slot 548 can be formed between the tip portion of the coupling tab 504 and the outer surface of the cover body portion 502. The slot 548 extends between the tubing passage 546 and the outer surface of the coupling tab 504. The slot 548 is oriented to extend in a direction toward the base portion of the coupling tab 504 between the tubing passage 546 and the outer surface of the coupling tab 504.

[0104] The coupling tab 504 is shaped as a wall portion having a predetermined height, width, and length. The height of the coupling tab 504 extends between the proximal surface (facing the direction of the proximal end 506) and the distal surface (facing the direction of the distal end 508). The length of the coupling tab 504 is in the direction from the base portion 562 to the tip portion 566, and the width of the coupling tab 504 is in a direction transverse to the length of the coupling tab 504.

[0105] Any of the base portion 562, the intermediate portion 564, and the tip portion 566 can have a height that decreases along the length of each portion. The base portion 562 can have a height H10, the tip portion 566 can have a height H12, and the height H12 is smaller than the height H10. Between the base portion 562 and the tip portion 566, the intermediate portion 564 includes a height that decreases from the height H10 to the height H12.

[0106] The width of the coupling tab 504 is smaller than the heights H10 and H12. The width of the coupling tab 504 and the reduced height of the tip portion 566 relative to the base portion 562 provide a more flexible coupling tab 504 in the area adjacent to the tip portion 566 compared to the area adjacent to the base portion 562. The flexibility of the tip portion 566 can be enabled such that the tip portion 566 becomes flexible and is moved away from the cover body portion 502. On the other hand, the less flexible base portion 562 resists damage to the IV priming cap 500 when the coupling tab 504 is connected to an IV line or other structure.

[0107] With respect to the width, the high height of the coupling tab 504 provides a large inner surface area of the coupling tab 504 to engage a predetermined length of the IV line inserted into the tubing passage 548. The engagement of the inner surface of the coupling tab 504 resists the slide or movement of the IV line relative to the IV priming cap 500.

[0108] The length L10 of the coupling tab 504 is smaller than the cross-sectional length L12 of the cover body portion 502 adjacent to the proximal end portion 506. The length L10 of the coupling tab 504 is approximately equal to the height H10 of the base portion 562. Since the length L10 of the coupling tab 504 is approximately equal to the height H10 of the base portion 562, the coupling tab 504 is less flexible compared to a coupling tab 504 having a length greater than the length L10 in the direction towards or away from the cover body portion 502.

[0109] The distal portion of the coupling tab 504 can include a protrusion 560 that has an outer surface extending away from the outer surface of the coupling tab 504. The protrusion 560 can be shaped into a cylindrical shape and can extend longitudinally along the height of the coupling tab 504. In some embodiments, the protrusion 560 can include a cross-sectional shape including any of circular, elliptical, semi-circular, and polygonal. In some embodiments, the cross-sectional profile of the protrusion 560 (in a direction transverse to the tubing passage axis 5B) includes a width that is tapered along the height of the coupling tab 504.

[0110] The tubing passage 546 and the slot 548 allow a predetermined length of IV line to be moved into the tubing passage 546. Also, the tubing passage 546 and the slot 548 can also allow the IV priming cap 500 to be connected to another structure (such as a pole or a clamp, etc.). When the coupling tab 504 is connected by a predetermined length of IV line, the predetermined length of IV line will generally be aligned and extend along the longitudinal tubing passage axis 5B, and the distal end portion of the IV line will generally be aligned along the longitudinal connector cavity axis 5A.

[0111] In some embodiments of the present disclosure, the IV priming cap 500 includes an elongated clip-shaped coupling tab 504 as illustrated in FIGS. 8A - 8D. The elongated coupling tab 504 includes a length that is long relative to the height of the coupling tab 504.

[0112] The base portion 562 has a height H10, and the tip portion 566 can have a height H14, which is smaller than the height H10 and the height H12. Between the base portion 562 and the tip portion 566, the intermediate portion 564 includes a height that decreases from the height H10 toward the height H14. In some embodiments, the height H10 of the base portion 562 is smaller than the height H14 of the tip portion 566, and the height of the intermediate portion 564 can increase from the height H10 toward the height H14.

[0113] The length L14 of the elongated coupling tab 504 is approximately equal to the cross-sectional length L12 of the cover body portion 502 adjacent to the proximal end portion 506. The length L14 of the coupling tab 504 is greater than the height H10 of the base portion 562. In some embodiments, the length L14 of the coupling tab 504 is twice the length of the height H10 of the base portion 562.

[0114] Since the length L14 of the elongated coupling tab 504 is greater than the height H10 of the base portion 562, the elongated coupling tab 504 is more flexible in the direction toward the cover body portion 502 or away from the cover body portion 502 than a coupling tab 504 having a length of H10 or less.

[0115] Since the elongated coupling tab 504 is more flexible, a predetermined length of the IV line positioned between the cover body portion 502 and the elongated coupling tab 504 may not be compressed, thereby allowing an unobstructed flow through the IV line. Additionally, the elongated coupling tab 504 can be used to connect an IV priming cap to other structures (such as a railing, etc.).

[0116] Referring to FIGS. 9A - 9D, another embodiment of the IV priming cap 600 having a clip - shaped coupling tab 604 is illustrated. The IV priming cap 600 can include features similar to those described with reference to other embodiments disclosed herein. As such, the description of some of the similar features is not repeated herein for purposes of clarity and brevity.

[0117] The IV priming cap 600 includes a cover body portion 602 and a coupling tab 604. The cover body portion 602 includes a proximal end portion 606 and a distal end portion 608, and the distal end portion 608 is on the opposite side of the proximal end portion 606. The inner surface 610 of the cover body portion 602 defines a cavity that extends into the cover body portion 602 and is configured to receive a fluid connector therein. The longitudinal connector - cavity axis 6A extends between the proximal end portion 606 and the distal end portion 608 of the cover body portion 602.

[0118] The coupling tab 604 of the IV priming cap 600 extends away from the cover body portion 602 in a direction transverse to the connector - cavity axis 6A. The coupling tab includes a base portion 662 connected to the cover body portion 602 and a tip portion 666 extending from the base portion 662. The base portion 662 extends from the cover body portion 602 in a first direction, and the tip portion 666 extends from the base portion 662 in a second direction, which is different from the first direction.

[0119] The coupling tab 604 includes side surfaces that extend along the base portion 662 and the tip portion 666. At least a portion of the side surface of the base portion 662 and the side surface of the tip portion 666 face opposite each other and are spaced apart to form a tubing passage 646.

[0120] The tubing passage 646 extends through the coupling tab 604 between a proximal surface (facing the direction of the proximal end 606) and a distal surface (facing the direction of the distal end 608). The tubing passage 646 is oriented through the coupling tab 604 and forms a longitudinal tubing passage axis 6B, and the longitudinal tubing passage axis 6B is parallel to the longitudinal connector cavity axis 6A. In some embodiments, the tubing passage axis 6B extends at an angle transverse to the connector cavity axis 6A. Additionally, the side surfaces of the base portion 662 and the tip portion 666 form slots 648. The slots 648 extend between the tubing passage 646 and the outer surface of the coupling tab 604.

[0121] The side surfaces of the base portion 662 and the tip portion 666 that form the slots 648 and the tubing passage 646 can extend generally parallel to each other, can be tapered towards each other, and can be tapered away from each other.

[0122] Referring to FIG. 9C, the width between the side surface of the base portion 662 and the side surface of the tip portion 666 decreases along a first length and can form a tapered slot 648. Then, the width between the side surfaces increases from the slot 648 to the tubing passage 646.

[0123] The width between the side surfaces of the coupling tab 604 that form the tubing passage 646 and the slots 648 can be smaller than the diameter of the IV line, and a predetermined length of the IV line is configured to be compressed when moved into the tubing passage 648.

[0124] The distal surface includes a recessed surface 650, and at least a portion of the peripheral portion of the coupling tab 604 includes a wall portion 652 that extends above the recessed surface 650. In some embodiments of the present disclosure, either the proximal surface or the distal surface of the coupling tab 604 can include a recessed surface. The recessed surface 650 and the wall portion 652 provide structural rigidity while reducing the amount of material required to form the coupling tab 604.

[0125] The base portion 662 extends along the outer surface of the cover body portion 602 over an angle 6C about the connector cavity axis 6C. In some embodiments, the base portion extends along the outer surface of the cover body portion 602 over an angle of about 90 degrees about the connector cavity axis 6A.

[0126] The tubing passage 646 and the slot 648 allow a predetermined length of IV line to be moved into the tubing passage 646. When a predetermined length of IV line is inserted into the tubing passage 646 through the slot 648, the rigidity of the coupling tab 604 resists deformation or movement of the coupling tab 604 relative to the IV line.

[0127] In use, a predetermined length of IV line is compressed when it is moved into the tubing passage 646 of the IV priming cap 600 along the narrowing portion of the width of the slot 648 (FIG. 12). The cross-sectional width of the tubing passage 646 can be configured to completely or partially block the fluid passage through the IV line.

[0128] Referring to FIGS. 10A - 10D, another embodiment of an IV priming cap 700 having a hook - shaped coupling tab 704 is illustrated. The IV priming cap 400 can include features similar to those described with reference to other embodiments disclosed herein. As such, descriptions of some of the similar features are not repeated herein for clarity and brevity.

[0129] The IV priming cap 700 includes a cover body portion 702 and a coupling tab 704. The cover body portion 702 includes a proximal end 706 and a distal end 708, and the distal end 708 is opposite the proximal end 706. The inner surface 710 of the cover body portion 702 defines a cavity that extends into the cover body portion 702 and is configured to receive a fluid connector therein. A longitudinal connector - cavity axis 7A extends between the proximal end 706 and the distal end 708 of the cover body portion 702.

[0130] The coupling tab 704 of the IV priming cap 700 extends away from the cover body portion 702 in a direction transverse to the connector - cavity axis 7A. The coupling tab includes a base portion 762 connected to the cover body portion 702 and a tip portion 766 distal to the cover body portion 702.

[0131] The base portion 762 extends from the cover body portion 702 in a first direction, and the tip portion 766 extends from the base portion 762 in a second direction, and the second direction is different from the first direction.
