Description

Technical Field

[0001] The present disclosure generally relates to a medical infusion fluid line connector, and more specifically, to a vacuum Luer lock connector. This vacuum Luer lock connection maintains the connection by generating a vacuum force within a vacuum chamber surrounding the male and female Luer components of the connector. The connection can be easily disconnected by allowing external air to flow into the vacuum chamber through a designed vent channel. Background Art

[0002] Patients typically receive an IV solution that is initially provided in an IV reservoir (bottle or bag) and dripped into the patient's vein through an IV line. Typically, an injection port is provided along the IV line and is adapted to function with a syringe to allow injections to be added to the IV solution. Medical infusion fluid line connectors provide a dedicated, secure path for fluid aspiration, medication, or blood withdrawal via a peripheral, arterial, or central venous catheter.

[0003] Traditional Luer lock connectors rely on friction between two tapered Luer pieces, which push against each other through the mechanical advantage of their tapered shape and the screw mechanism (Luer nut). This results in high contact forces over a large area of ​​contact for sealing purposes, which also makes it difficult for users to disconnect the Luer pieces. On the other hand, some fluids (such as blood, alcohol, and some medications) can dry between the two connections and cause the two contacting surfaces to stick. This further complicates the disconnection process. This type of connection is easy to connect but difficult to disconnect because there is no control over the forces involved. Utility Model Content

[0004] The present disclosure relates generally to a luer connector, and more particularly, to a vacuum luer lock connector.

[0005] According to various embodiments of the present disclosure, a vacuum Luer lock connector includes: a male Luer configured to couple to a female Luer defining a fluid pathway; a vacuum chamber located between the male and female Luer components that traps air when the male Luer component is pushed into the female Luer component; a solid cylinder that surrounds the male Luer component and serves as a piston; a cylindrical member that surrounds the female Luer component and serves as a wall of the vacuum chamber; and a vent channel in the female Luer component that allows air to escape when the male Luer component is pushed into the female Luer component. The male and female Luer components maintain connection through a force generated in the vacuum chamber surrounding the Luer components.

[0006] Embodiments of the present disclosure provide a vacuum luer lock connector comprising: a male luer configured to couple to a female luer defining a fluid pathway; a vacuum chamber located between the male and female luer components, the vacuum chamber trapping air when the male luer component is pushed into the female luer component, wherein the male and female luer components remain connected by a force developed in the vacuum chamber surrounding the male and female luer components.

[0015] The detailed description set forth below describes the various configurations of the subject technology and is not intended to represent the only configuration that can be put into practice. The specific embodiment includes specific details to provide a thorough understanding of the subject technology. Therefore, dimensions about certain aspects can be provided as non-limiting examples. However, it is clear to those skilled in the art that the subject technology can be implemented without these specific details. In some cases, well-known structures and components are shown in block diagram form to avoid blurring the concept of the subject technology.

[0016] It should be understood that the present disclosure includes examples of the subject technology and does not limit the scope of the appended claims. The following will illustrate various aspects of the subject technology based on specific but non-limiting examples. The various embodiments described in this disclosure can be implemented in different ways and variations and according to the intended application and implementation.

[0017] The present disclosure relates generally to infusion fluid line connectors and, more particularly, to vacuum Luer lock connectors that are held together with a vacuum seal, for example but not limited to. According to some embodiments, the vacuum Luer lock connector can be a two-piece assembly that includes a male Luer and a female Luer.

[0018] In some embodiments, a vacuum Luer lock connector is used in an IV dosing kit having a structure for coupling with an IV bag and / or a drip chamber. The structure of the IV bag can be formed as an arm, a hook, a clamp, or another mechanism configured to suspend the IV bag.

[0019] refer to Figure 1 , an embodiment of an IV administration set 2 is coupled to a patient 1. The IV administration set 2 can include a vacuum Luer lock connector 100. The IV administration set includes an IV bag 12 and a drip chamber 14, which are fluidly coupled together by IV tubing 16 extending therebetween. The IV tubing 16 is coupled intravenously to the patient 1 via a catheter 18, which preferably includes one or more adapters 10 or connectors 20.

[0020] Reference Figure 2-3B , shows an embodiment of a vacuum Luer lock connector 100, which includes: a male luer 102, which is configured to be coupled to a female luer 101 that defines a fluid passageway 106; a vacuum chamber 105, which is located between the male luer 102 and the female luer 101, and which traps air when the male luer 102 is pushed into the female luer 101; a solid cylinder 108, which surrounds the male luer 102 and acts as a piston; a cylindrical member 107, which surrounds the female luer 101 and acts as a wall of the vacuum chamber 105; and a vent channel 109 in the female luer 101, which allows air to escape when the male luer 102 is pushed into the female luer 101. The male and female luer pieces 102, 101 are maintained connected by forces generated within the vacuum chamber 105 surrounding the luer pieces. In some embodiments, the vacuum luer lock connector 100 includes an O-ring 103 or multiple O-rings 103 mounted within the female luer piece 101, which prevents infusion fluid from leaking into the vacuum chamber 105. In some embodiments, the vacuum luer lock connector 100 includes a check valve 104 on the outer surface of the vent channel 109, which prevents air from flowing back into the vacuum chamber 105. When the male and female luer pieces 102, 101 are connected, the check valve 104 allows air or gas to escape from the vacuum chamber 105. In some embodiments, the check valve 104 can function as a one-way valve, allowing air to escape from the vacuum chamber 105 while limiting or preventing air from entering the vacuum chamber 105 after the luers 102, 101 are connected.

[0021] In some embodiments, the vacuum luer lock connector 100 includes a second vent channel 110 in the solid cylinder 108 of the male luer 102, connecting the compressed area 111 of the male luer 102 to a surface 112 of the male luer 102 that mates with the female luer 101, the surface 112 being perpendicular to the longitudinal axis X of the male luer 102. In some embodiments, a slot 113 is formed on the inner surface of the cylindrical member 107. In some embodiments, the slot 113 extends from the edge of the cylindrical member 107 of the female luer 101 that mates with the male luer 102 in a direction away from the male luer 102 along the longitudinal axis X of the cylindrical member 107. In some embodiments, the second vent channel 110 and the slot 113 should not be aligned with each other along the longitudinal axis of the connector to maintain an adequate vacuum seal. In some embodiments, when the male and female luer components 102, 101 are rotated to a position where the second vent channel 110 is aligned with the slot 113 along the longitudinal axis of the vacuum Luer lock connector 100, air rushes into the vacuum chamber 105 and the vacuum seal is lost, allowing the male and female luer components 102, 101 to be easily disconnected. In some embodiments, the tip 114 of the male luer component 102 separates the vacuum chamber 105 from the fluid pathway 106. In some embodiments, the vacuum Luer lock connector 100 includes a "LOCK" indicator to inform the user if the second vent channel 110 and the slot 113 are misaligned and if the vacuum Luer lock connector 100 remains connected. In some embodiments, the vacuum Luer lock connector 100 includes an "UNLOCK" indicator to inform the user if the second vent channel 110 and the slot 113 are aligned and if the vacuum Luer lock connector 100 remains connected. The vacuum force is strong and controllable, and it does not rely on high contact force to maintain and seal the connection. Furthermore, the use of the O-ring 103 prevents the contact surface from being exposed to the liquid and generates sufficient sealing pressure over a significantly smaller surface area. This combination allows for a safe and secure connection while being easy to disconnect.

[0022] refer to Figure 4, an embodiment of a vacuum Luer lock connector 200 is shown. The vacuum Luer lock connector includes: a male luer 202 configured to couple to a female luer 201 defining a fluid pathway 206; a vacuum chamber 205 located between the male and female luer 202, 201, which traps air when the male luer 202 is pushed into the female luer 201; a solid cylinder 208 surrounding the male luer 202 and acting as a piston; a cylindrical member 207 surrounding the female luer 201 and acting as a wall of the vacuum chamber 205; a second cylindrical member 215 separating the fluid pathway 206 from the vacuum chamber 205 to prevent fluid exposure and contamination; and a vent channel 209 in the female luer 201, which allows air to escape when the male luer 202 is pushed into the female luer 201. In some embodiments, the male luer 202 further includes a vent channel 216. The male luer 202 and the female luer 201 remain connected by forces generated within the vacuum chamber 205 surrounding the luers. In some embodiments, the vacuum luer lock connector 200 includes an O-ring 203 or multiple O-rings 203 mounted within the female luer 201 to prevent infusion fluid from leaking into the vacuum chamber 205. In some embodiments, the vacuum luer lock connector 200 includes a check valve 204 on the outer surface of the vent channel 109 to prevent air from flowing back into the vacuum chamber 205.

[0023] In some embodiments, the vacuum Luer lock connector 200 includes a second vent channel 216 in the male Luer piece 202 that connects the vacuum chamber to the exterior of the connector. In some embodiments, the second vent channel 216 includes a check valve. The vacuum force is strong and controllable, and it does not rely on high contact force to maintain and seal the connection. In addition, the use of the O-ring 203 prevents the contact surface from being exposed to liquids and creates sufficient sealing pressure over a significantly smaller surface area. This combination allows for a safe and secure connection while being easy to disconnect.
