Description

Technical Field

[0001] The present invention generally relates to an infusion set intravenous (IV) connector, and more particularly to a male luer connector.

Background Art

[0002] A typical infusion set or intravenous (IV) set is composed of connecting polymer tubing pieces to polymer components, and often uses luer connectors. These IV sets can be used with an infusion pump or a gravity system to supply fluid to a user such as a patient. However, typical luer connectors generally sacrifice one function to optimize another. For example, in order to have a better gripping portion, typical luer connectors tend to be bulky and / or have sharp features, resulting in higher costs and adverse effects on patient comfort. In some applications, typical luer connectors can be formed from acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), or acrylic.

Summary of the Invention

[0003] A luer connector made of acrylonitrile butadiene styrene (ABS), polyvinyl chloride (PVC), acrylic or other similar materials may deteriorate after chemical exposure. The deteriorated luer connector may be prone to cracks and / or breakage. In some applications, the deteriorated luer connector may be prone to unintended chemical bonding and may prevent the separation of the luer connector.

[0004] For these reasons, it is desirable to provide male luer connectors for IV components and IV sets that optimize key aspects of male luer connectors (e.g., connection, disconnection, cleaning, and comfort) in a single integrated design. It is also desirable to provide male luer connectors for IV components and IV sets that are resistant to degradation due to chemical exposure.

[0005] According to at least some embodiments disclosed herein, it is recognized that certain conventional connectors are difficult to grasp, manipulate, or otherwise operate with one hand or a single motion, are difficult to disconnect, and / or clean, which may result in clinicians requiring additional time to connect and disconnect fluid connections. Furthermore, according to at least some embodiments disclosed herein, it is recognized that certain conventional connectors are bulky and may cause patient discomfort and unintended disconnection. Furthermore, according to at least some embodiments disclosed herein, it is recognized that certain conventional connectors are formed from materials that may degrade when exposed to chemicals such as medical fluids and / or solvents, which may result in cracking, leakage, and / or contamination of medical fluids.

[0006] Accordingly, aspects of the present disclosure provide a connector including a first connector portion. The first connector portion includes: a Luer slip having a first end and a second end, defining a lumen extending between the first end and the second end, the first end of which is configured to engage with a mating connector; a collar disposed around the Luer slip, movable relative to the Luer slip, and configured to connect with the mating connector adjacent to the first end of the Luer slip; and a spigot defining a fluid port, the spigot being connected to the Luer slip, the fluid port being in fluid communication with the lumen at the second end of the Luer slip.

[0007] In some examples, the Disclosure provides an infusion set comprising: an infusion set component; a tube connected to the infusion set component; and a male Luer connector, the male Luer connector having a first end and a second end, and a Luer slip defining a lumen between the first end and the second end, wherein the first end is configured to engage with a mating connector, and the Luer slip includes a Luer slip connected to the tube.

[0008] In some examples, the Disclosure relates to a connector assembly comprising a female Luer connector, the female Luer connector comprising a receiving portion; a first fluid port configured to receive an intravenous tube; and a female Luer connector lumen fluidly connected between the receiving portion and the first fluid port; and a male Luer connector, the male Luer connector comprising a Luer slip having a first end and a second end and a plurality of projections extending radially from the slip surface, defining a lumen extending between the first end and the second end, the first end configured to engage with a mating connector; and a plurality of notches disposed around the Luer slip corresponding to the plurality of projections of the Luer slip. A connector assembly is provided, comprising a collar defining a lumen, the collar being movable relative to the luer slip, the collar being configured to connect with the mating connector adjacent to the first end of the luer slip, the collar having a plurality of notches that engage with a plurality of projections when the collar is spaced apart from the first end of the luer slip, selectively rotating the collar and the luer slip together; and a male luer connector comprising a spigot having a teardrop shape and defining a fluid port, the spigot being connected to the luer slip, the fluid port being in fluid communication with the lumen at the second end of the luer slip, and the spigot defining at least one gripping portion.

[0009] Therefore, this application addresses several operational challenges faced in conventional fluid connections and provides numerous improvements that enable users to perform fluid connections more easily while increasing safety and effectiveness.

[0014] The detailed description below illustrates various configurations of the subject art and does not represent the only configurations that may implement the subject art. The detailed description includes specific details for the purpose of providing a thorough understanding of the subject art. Accordingly, dimensions are provided as non-limiting examples with respect to certain embodiments. However, it will be apparent to those skilled in the art that the subject art may be implemented without these specific details. In some examples, well-known structures and components are shown in block diagrams to avoid obscuring the concepts of the subject art.

[0015] It should be understood that this disclosure encompasses examples of the subject art and does not limit the scope of the appended claims. Here, various aspects of the subject art are disclosed according to certain but non-limiting examples. The various embodiments described in this disclosure can be carried out in different ways and variations and may be carried out according to the desired use or embodiment.

[0016] According to several embodiments, this application discloses various features and advantages of fluid connectors. The connectors described in the present invention provide features that allow clinicians to easily grasp, manipulate, connect, and disconnect the connector during operation, avoiding the use of additional tools for operating the connector. Furthermore, the connectors described in the present invention may include features that allow for easier cleaning. In some applications, the connectors can have a small profile or overall dimensions and be formed without sharp edges, improving patient comfort. Furthermore, certain connectors can be formed from materials resistant to degradation by chemical exposure, preventing cracking, leakage, and unintended coupling. In some applications, certain connectors can be mechanically connected to tubing without the use of adhesives. In some applications, certain connectors can be configured for use with tubing of various sizes, minimizing the number of different types of connectors required for manufacturing and inventory.

[0017] Further detailed reference to the drawings reveals that the same reference numerals indicate the same or corresponding elements in multiple figures. Figure 1 shows a patient care system 20 having four infusion pumps 22, 24, 26, and 28, each of which is fluidically connected to upstream fluid lines 30, 32, 34, and 36. Furthermore, each of the four infusion pumps 22, 24, 26, and 28 is also fluidically connected to downstream fluid lines 31, 33, 35, and 37. The fluid lines may be any type of fluid conduit through which fluid can flow, such as an IV administration set. It should be understood that any type of pump mechanism, including a syringe pump, can be used.

[0018] Fluid sources 38, 40, 42, and 44 can take various forms, but in this example are shown as bottles, hung upside down above the pumps. The fluid sources can also take the form of other types of containers, including bags or syringes. Patient care system 20 and fluid sources 38, 40, 42, and 44 are attached to a roller stand, an IV pole 46, a tabletop, etc.

[0019] Separate infusion pumps 22, 24, 26, and 28 are used to inject the fluid from each fluid source into the patient. The infusion pumps are fluid control devices that act on their respective fluid lines to transfer fluid from the fluid source through the fluid line to patient 48. Because individual pumps are used, each can be individually set to the pumping or operating parameters necessary to infuse the fluid at the specific rate prescribed by the physician for that fluid from the corresponding fluid source to the patient. Such medical fluids can include drugs, nutrients, or other fluids. Infusion pumps 22, 24, 26, and 28 are controlled by a pump control unit 60.

[0020] Fluid sources 38, 40, 42, and 44 are each connected to an electronic data tag 81, 83, 85, and 87, respectively, or an electronic transmitter. Any device or component associated with the infusion system can be equipped with an electronic data tag, a reader, or a transmitter.

[0021] A typical infusion set may be a gravity set that does not require the use of an infusion pump. For example, any one of fluid sources 38, 40, 42, and 44 can be directly connected to patient 48 via a gravity IV set, in which case the fluid flows through the infusion set by gravity and is delivered to patient 48 without using a pump.

[0022] Typically, medical fluid administration sets have more components than those shown in Figure 1, including components as shown in Figures 2A to 2C. Infusion sets can be formed from any combination of infusion components and tubing. Typically, infusion components and tubing are disposable products that are discarded after a single use. Infusion components and tubing can be formed from any suitable material (e.g., plastic, silicone, rubber), and many or all of them are transparent or translucent so that the flow or level of the fluid inside can be observed.

[0023] As shown in Figure 2A, the infusion set 120 may include an infusion chamber 130, a check valve 140, and a roller clamp 150, all connected to each other by a tube 160. The infusion set 120 may also include a Y-site 170 with a Y-shaped joint having a needleless connector 175, and a Luer lock connector 180 at the end of the infusion set 120. The Luer lock connector 180 can be used to connect to a catheter inserted into the patient or to any other suitable tube or component. The infusion set 120 may include additional infusion components, which can be formed from any combination of components and tubes 160.

[0024] As shown in Figure 2B, the IV extension set 120a can be used to connect any two infusion components or devices, such as an IV set, an infusion pump, or a syringe pump. The IV extension set 120a includes a Luer connector 180a and a flow controller 155a. Similarly, as shown in Figure 2C, another IV extension set 120b includes a Luer connector 180b and a flow controller 155b.

[0025] Referring to Figures 3 and 4, a male Luer connector 200 according to an aspect of the present disclosure is provided. In the illustrated example, the male Luer connector 200 facilitates physical connection and fluid flow between components of a tube and / or IV set. In the illustrated example, the male Luer connector 200 includes a Luer slip 210 that defines a flow path between the ends of the male Luer connector 200. As shown, the Luer slip 210 includes a hollow body that defines a lumen 216 along its length.

[0026] As described herein, the male Luer connector 200 and its components may be formed from chemical-resistant materials. Advantageously, by forming the components of the male Luer connector 200 from chemical-resistant materials, the male Luer connector 200 can withstand degradation even after exposure to medical fluids and / or other chemicals. In the illustrated example, the Luer slip 210 and / or other components of the male Luer connector 200 may be formed from chemical-resistant materials. In some applications, the Luer slip 210 is formed from polypropylene. Advantageously, certain polypropylene resins may be more cost-effective than acrylonitrile butadiene styrene. In some applications, the Luer slip 210 may be formed from other suitable materials, including but not limited to polycarbonate, nylon, or polyethylene.

[0027] In the illustrated example, the male Luer connector 200 is connected to a tube, terminating the end of the tube and facilitating fluid connection. As described herein (see Figures 7 to 10), the male Luer connector 200 can be used in one or more configurations to connect tubes of various sizes or types to the male Luer connector 200. For example, the male Luer connector 200 may be adapted, adjusted or otherwise configured for use with at least the following types of tubes: (i) Microbore (T0.5×2.3) - Tube outer diameter (OD): approx. 2.30 mm / 0.091 inches; Tube inner diameter (ID): approx. 0.50 mm / 0.020 inches; Wall thickness: approx. 0.90 mm / 0.035 inches (ii) Small bore (T1 x 2.3) - Tube outer diameter: approx. 2.30 mm / 0.091 inches; Tube inner diameter: approx. 1.00 mm / 0.039 inches; Wall thickness: approx. 0.65 mm / 0.026 inches (iii) Standard Bore Thick Wall (T1.5 x 3.7) - Tube outer diameter: approx. 3.70 mm / 0.146 inches; Tube inner diameter: approx. 1.50 mm / 0.059 inches; Wall thickness: approx. 1.10 mm / 0.043 inches (iv) Standard bore (T2.7 x 3.7) - Tube outer diameter: 3.70 mm / 0.146 inches; Tube inner diameter: approx. 2.70 mm / 0.106 inches; Wall thickness: approx. 0.50 mm / 0.020 inches (v) Macro bore (T3×4.2) - Tube outer diameter: approx. 4.20 mm / 0.165 inches; Tube inner diameter: approx. 3.00 mm / 0.118 inches; Wall thickness: approx. 0.60 mm / 0.024 inches.

[0028] In some applications, the tube dimensions can have the following tolerances: outer diameter: approximately 0.08 mm / 0.003 inches; inner diameter: approximately 0.05 mm / 0.002 inches; wall thickness: approximately 0.09 mm / 0.004 inches. Advantageously, by enabling the connection of various types or sizes of tubes (e.g., microbore tubes, smallbore tubes, standard bore tubes, and macrobore tubes) to the male Luer connector 200, the design of a single male Luer connector 200 can be utilized with multiple types or sizes of tubes, simplifying the number of connector types required for IV set connections, reducing inventory, and simplifying manufacturing.

[0029] In some applications, the male lure connector 200 may be configured to connect the tube directly to the lure slip 210, or to connect the tube to the spigot 230, which is connected to the lure slip 210. Advantageously, the multiple configurations of the male lure connector 200 allow tubes of various sizes to be connected to the male lure connector 200.

[0030] In some configurations, the tube is directly connected to the end of the Luer slip 210. The tube can be received within the lumen 216 of the Luer slip 210. Optionally, the Luer slip 210 can define a pocket within the lumen 216 or concentrically with the lumen 216 to receive the tube. In some applications, the tube can be adhesively connected within the Luer slip 210. The adhesive can be UV cured or activated. In some applications, a microbore tube or a smallbore tube can be connected to the Luer slip 210.

[0031] In some applications, the tube is connected to a spigot 230, which in turn is connected to a luer slip 210 of a male luer connector 200. Optionally, the tube can be received into a fluid port 236 of the spigot 230. The tube can be mechanically connected to the spigot 230. Optionally, the tube can be held between the luer slip 210 and the spigot 230, and the spigot 230 can be mechanically connected. In some applications, mechanical connection between the tube and the spigot 230 eliminates the need for adhesives or any other binders. Advantageously, the use of mechanical connection minimizes solvent exposure and environmental impact on the connector.

[0032] In the illustrated example, the spigot 230 is connected to the Luer slip 210. In some applications, the spigot 230 is circumferentially arranged around the Luer slip 210. The spigot 230 may be formed separately from the Luer slip 210 (e.g., by molding) or integrally with the Luer slip 210. In some applications, the spigot 230 can seal against the Luer slip 210 to minimize leakage. Advantageously, the arrangement of the male Luer connector 200 and the use of mechanical coupling can simplify the design of the joint and reduce the risk of leakage, separation, and / or blockage. Furthermore, the assembly of the joint can be easily automated. In some applications, a standard bore tube or a macrobore tube may be connected to the male Luer connector 200 via a spigot 230 connected to the Luer slip 210.

[0033] In the illustrated example, the spigot 230 can be formed from a chemical-resistant material. In some applications, the spigot 230 is formed from polypropylene. Advantageously, the mechanical connection of the tube can be made from a material that does not readily bond with solvents, such as polypropylene. In some applications, the spigot 230 can be formed from other suitable materials, including but not limited to polycarbonate, nylon, or polyethylene.

[0034] Furthermore, in some applications, the spigot 230 may be formed from a soft, cushioning material such as silicone, polyurethane, latex-free silicone rubber, or any combination thereof. In this case, the material of the spigot 230 is overmolded onto the Luer slip 210 or otherwise bonded, and the soft, cushioning properties of the spigot 230 prevent skin lacerations or pressure sores even when the male Luer connector 200 is pressed against the patient's skin for extended periods. The spigot 230 may be latex-free and can be used in a wide range of medical applications, including applications where latex contact with the patient's skin is prohibited (e.g., when the patient has a latex allergy). The spigot 230 may be formed to withstand gas sterilization and gamma ray sterilization.

[0035] In the illustrated example, the male Luer connector 200 can engage with a standard female receptacle. For example, the male Luer connector 200 can mate with the connectors of an infusion set device or component (e.g., a female Luer connector, a female needle-free port, a female catheter set, a female pump port) configured to connect to the male Luer connector. In the illustrated example, the opposite end of the Luer slip 210 may be configured to engage with a mating female Luer connector.

[0036] In the illustrated example, the collar 220 connects and secures the male luer connector 200 to the mating connector after the luer slip 210 has engaged with the mating connector. In some applications, the collar 220 can be rotated to screw into the threads of the mating connector, thereby connecting the male luer connector 200 to the female connector. Optionally, the collar 220 may use any other suitable engagement mechanism to connect the male luer connector 200 to the mating connector.

[0037] As illustrated, the collar 220 is positioned around the Luer slip 210 and coupled to the Luer slip 210. In some embodiments, the collar 220 is slidably coupled to the Luer slip 210, allowing the collar 220 to slide relative to the Luer slip 210. Optionally, the sliding range of the collar 220 may be limited or configured to provide the ability to securely grip the male Luer connector 200 while allowing the Luer slip 210 to fully engage with the female Luer connector 300 (e.g., the female Luer connector 300 shown in Figure 5) before the collar 220 contacts the female Luer connector 300. Advantageously, the sliding range of the collar 220 can be selected to ensure a leak-free connection between the male Luer connector 200 and the female Luer connector 300. Furthermore, the sliding range of the collar 220 may be configured to give the user (e.g., healthcare provider, clinician) more space to clean the Luer slip 210. Optionally, the sliding range of the collar 220 may be configured or restricted for any appropriate purpose.

[0038] In the illustrated example, color 220 can be formed from a chemical-resistant material. In some applications, color 220 is formed from polypropylene. In some applications, color 220 can be formed from other suitable materials, including but not limited to polycarbonate, nylon, or polyethylene.

[0039] As another example, the collar 220 may be formed from a soft, cushioning material such as silicone, polyurethane, or latex-free silicone rubber, or any combination thereof. In this case, the soft, cushioning properties of the collar 220 prevent skin lacerations or pressure sores even when the male Luer connector 200 is pressed against the patient's skin for extended periods. The collar 220 may be latex-free and can be used in a wide range of medical applications, including applications where latex contact with the patient's skin is prohibited (e.g., when the patient has a latex allergy). The collar 220 may have an anti-slip effect when wet and may be formed to withstand gas sterilization and gamma ray sterilization.

[0040] The collar 220 may be textured and / or contoured to improve grip when loosening or tightening the male luer connector 200. For example, as shown in Figures 3 and 4, the collar 220 may have a plurality of raised parts 222, such as angled projections with rounded tips as shown, which can form a texture to provide anti-slip and / or easy gripping properties (e.g., a gripping mechanism). The raised parts 222 may be any suitable features, such as ridges or other raised parts.

[0041] In some embodiments, the male luer connector 200 includes features for holding the collar 220 in an engaged position relative to the luer slip 210 in order to facilitate separation and / or removal of the male luer connector 200 from the mating female luer connector. As shown, the luer slip 210 includes one or more projections 212 extending radially from its surface, which can hold the collar 220 in a desired engaged or coupled position. In some embodiments, one or more projections 212 engage with the collar 220, holding the collar 220 in a desired rotational position relative to the luer slip 210, preventing the collar 220 from unintentionally slipping or rotating relative to the luer slip 210.

[0042] In the illustrated example, the collar 220 includes one or more notches 224 that selectively engage with the Luer slip 210 to prevent the collar 220 from rotating relative to the Luer slip 210. As shown, the notches 224 may be formed as circumferential recesses on the trailing edge of the collar 220. When the collar 220 is separated from the mating connector, the collar 220 slides back distally, i.e., towards the projection 212, allowing the notches 224 of the collar 220 to engage with the projection 212 of the Luer slip 210. In some embodiments, the collar 220 is rotated so that the notches 224 engage with the projection 212 of the Luer slip 210, preventing the collar 220 from rotating further relative to the Luer slip 210 during separation. Furthermore, the notch 224 may be formed at an angle or inclination to facilitate rotational alignment and engagement with the projection 212 of the Luer slip 210, increase the engagement force, and / or prevent the collar 220 from slipping or rotating relative to the Luer slip 210 during separation. Optionally, the notch 224 and / or projection 212 may be sized, shaped, or otherwise configured to provide tactile or auditory feedback, such as a "click" sensation or sound, upon engagement. Advantageously, the selective engagement of the collar 220 with the Luer slip 210 allows the clinician to separate the male Luer connector 200 in a single motion without the collar 220 rotating relative to the Luer slip 210, increasing stability and preventing unintended or sudden ejection of components of the male Luer connector 200 during separation.

[0043] As illustrated, the spigot 230 can be used as a gripping part for the clinician. In the illustrated example, the spigot 230 may be sized and shaped so that the clinician can easily and comfortably grip, hold and / or manipulate the male Luer connector 200. In some embodiments, the spigot 230 generally has a tapered teardrop shape. As illustrated, the spigot 230 further includes a gripping part 232 and a recess 234 to further enable the clinician to manipulate the spigot 230 and the male Luer connector 200 as a whole. In some embodiments, the gripping part 232 and the recess 234 may be arranged in an angled "shuriken" configuration.

[0044] In several applications, the shape and features of the spigot 230 facilitate the separation of the male Luer connector 200 from the mating connector by allowing a clinician to apply strong traction force. Advantageously, the shape and features of the spigot 230 can enable the separation of the male Luer connector 200 in applications where the Luer slip 210 is stuck or where high removal force is required for other reasons (e.g., when disinfectant is used in the connection). Furthermore, the shape and features of the spigot 230 allow its profile to be comfortably positioned between the clinician's fingers, reducing or avoiding pressure points. Advantageously, the gripping portion 232 and recess 234, as well as the overall arrangement of the spigot 230, allow for a non-slip grip when the male Luer connector 200 is wet. Additionally, the arrangement of the spigot 230 can also reduce the possibility of excessive torque being generated in the male Luer connector 200.

[0045] As described herein, the features of the male Luer connector 200 facilitate ease of use compared to certain conventional connectors. In some applications, the features of the male Luer connector 200, including but not limited to the sliding range of the collar 220 relative to the Luer slip 210, the selective engagement of the collar 220 and the Luer slip 210, and / or the gripping portion of the spigot 230, allow the male Luer connector 200 to be positioned and operated with one hand. As described herein, these features allow a clinician to quickly and easily twist, pull, or otherwise operate the male Luer connector 200 with one hand. In some applications, a clinician can twist and pull the male Luer connector 200 with one hand or one finger, allowing for quick and efficient separation of the male Luer connector 200.

[0046] Figure 5 shows an example of a Luer connector assembly 400 including a male Luer connector 200 and a female Luer connector 300. Here, the Luer slip 210 of the male Luer connector 200 engages with or mates with the female port 310 of the female Luer connector. For example, one of the male Luer connector 200 and the female Luer connector 300 may be connected to an IV set (e.g., IV set 120) via an IV tube, and the other may be connected to a catheter inserted into the patient via an IV tube. Thus, the male Luer connector 200 of the Luer connector assembly 400 allows for easy connection to or disconnection from the female Luer connector 300 with one-handed operation for rapid connection / disconnection between the IV set 120 and the catheter. As another example, the Luer connector assembly 400 is used between a fluid supply source (e.g., fluid supply source 38) and the receiving end of the IV set 120 (e.g., drip chamber 130), thereby enabling quick and easy connection / disconnection between the fluid supply source 38 and the IV set 120.

[0047] As shown in Figure 6, the male Luer connector 200 is smaller and smaller in size compared to a typical male Luer connector 180c. For example, the male Luer connector 200 has about half the volume of a typical male Luer connector 180c, and the combination of the above features allows the male Luer connector 200 to outperform the typical male Luer connector 180c. Here, this size difference between the male Luer connector 200 and a typical male Luer connector 180c means that the material cost (e.g., resin) of the male Luer connector 200 is halved by halving its volume. Furthermore, the smaller size of the male Luer connector 200 is more comfortable for patients, which may be particularly important for infants and neonates in the Neonatal Intensive Care Unit (NICU) or Premature Intensive Care Unit (PICU).

[0048] In embodiments of this disclosure, the male luer connector 200 can be formed in any suitable manner. For example, the luer slip 210 and spigot 230 may be molded as a single component, while the collar 220 may be molded as a separate component, and the collar 220 may then be slidably mounted onto the luer slip 210.
