[0002] Medical treatments typically include infusing medical fluids (e.g., saline solutions or liquid medications) to patients using an intravenous (IV) catheter, which is connected to a fluid source, such as an IV bag, by an arrangement of flexible tubing and accessories. An infusion kit is used to deliver medical fluids to patients via an IV catheter. An infusion kit includes an IV pump, a syringe, and / or a NFC (needle-free connector) for providing a fluid path to an IV catheter or a delivery line. NFC is a common means of quickly distributing fluids and / or medications to patients during treatment. In some applications, NFC may be overused, such as repeated use that exceeds the life of the NFC, thereby increasing the risk of infection, leakage, disconnection, or blockage. Utility Model Content

[0028] The disclosed tracking system includes a coupling device and a tracking device having at least two connectors (e.g., a first connector and a second connector). The two connectors may include a first connector and a second connector. The first connector may be a syringe, and the second connector may be a needleless connector (NFC) configured to receive the first connector. However, the two connectors may be any type of connector. The first connector is connected to a fluid source, and the second connector is connected to a portion of the tubing that is connected to the patient. The first connector and the second connector may include an infusion kit that is configured to allow rapid infusion of a fluid (e.g., a medical fluid) into a patient. The coupling device may have a coupling structure in which the first connector is coupled to the second connector for delivery of the fluid. The coupling device may also have an uncoupled structure in which the first connector is separated from the second connector. In some embodiments, the second connector remains coupled to the patient via the tubing, and the first connector is removably coupled to the second connector.

[0029] The coupling device can be switched to a coupled configuration for delivery of the fluid. After delivery of the fluid is completed, the coupling device can be switched to an uncoupled configuration. The coupling device can remain in an uncoupled configuration (e.g., the first connector is separated from the second connector) until another dose or fluid is needed, and then the coupling device is switched to a coupled configuration so that the first connector is coupled to the second connector to deliver the medical fluid to the patient.

[0030] The coupling device can be controlled by a flow control device (e.g., a pump). The flow control device is configured to control the flow of a medical fluid flowing to a patient. The flow control device is connected to the second connector via one or more pipes to control the flow of fluid from the second connector to the patient. For example, a user can deliver a medical fluid to a patient via the second connector, and the flow control device can control the flow of fluid (e.g., flow rate) to the patient. In some embodiments, the second connector is connected to another delivery line (e.g., a tube) to allow the medical fluid to be infused into the delivery line and infused into the patient. The flow control device can control the flow of fluid through the delivery line.

[0031] The coupling device includes a tracking system configured to track or monitor the number of times the second connector is used to deliver a medical fluid to a patient. For example, the tracking system is configured to track the number of times the coupling device enters a coupled configuration, indicating the number of times the first connector is coupled to the second connector to deliver a medical fluid. Tracking or monitoring the transition of the coupling device from a coupled configuration to an uncoupled configuration allows monitoring of usage of the coupling device. For example, each time the coupling device transitions from an uncoupled configuration to a coupled configuration indicates usage of the second connector and delivery of a medical fluid. Excessive use of the second connector may result in degradation of the second connector and may result in leakage, infection, blockage, or disconnection.

[0032] The tracking system includes a wireless transmitter coupled to the coupling device (e.g., coupled to the first connector and / or the second connector). In some embodiments, the wireless transmitter is a radio frequency identification (RFID) tag or transmitter. The wireless transmitter can be configured to communicate with the flow control device. In some embodiments, when the wireless transmitter is close to the flow control device, the flow control device can track and monitor the use of the coupling device.

[0033] The coupling device may include a shroud configured to block and unblock signals from a wireless transmitter. In some embodiments, when the coupling device is in a coupled configuration, the shroud unblocks signals from the wireless transmitter, thereby allowing it to communicate with the flow control device. Alternatively, when the coupling device is in an uncoupled configuration, the shroud unblocks signals from the wireless transmitter, thereby allowing it to communicate with the flow control device. The shroud is configured to block and unblock the wireless transmitter during transition of the coupling device from the coupled configuration to the uncoupled configuration. For example, coupling a first connector to a second connector may cause the shroud to unblock the wireless transmitter. In some embodiments, coupling a first connector to a second connector may cause the shroud to block the wireless transmitter.

[0034] The flow control device can be configured to monitor the state change of the wireless transmitter (e.g., blocked to unblocked or unblocked to blocked) to track the use of the connection device. In some embodiments, the flow control device includes a counter configured to count the state changes of the connection device. When the number of state changes of the connection device exceeds a predetermined threshold, the flow control device sends an alarm to indicate that the second connector needs to be replaced due to overuse or use beyond its shelf life. The second connector can be replaced, resulting in a new wireless transmitter and a reset of the counter of the flow control device.

[0035] The detailed description set forth below is intended to be a description of the various configurations of the subject technology, and is not intended to represent the unique configuration that can practice the subject technology. The specific embodiments include specific details for the purpose of providing a thorough understanding of the subject technology. 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. For ease of understanding, identical components are marked with identical element numbers. Reference numerals may be appended with letter suffixes to indicate the individual instances of common elements, while common elements are generally referred to by the same numerals without suffix letters.

[0036] Although the following description is directed to a tracking system for a medical connector, it should be understood that the description is merely an example of a use case and does not limit the scope of the claims. Various aspects of the disclosed tracking system may be used in any application where it is desirable to track the use of a medical connector or coupling.

[0037] The disclosed tracking system and coupler overcome several challenges found with certain conventional coupling devices. One challenge with certain conventional couplers is that certain conventional couplers may be overused or used beyond their shelf life. For example, certain conventional couplers may be used beyond their shelf life, resulting in coupler failure. This may lead to infection, blockage, disconnection, or other problems.

[0038] Therefore, according to the present disclosure, it is advantageous to provide a coupler and coupler / connector assembly as described herein that allows improved fixation of an accessory or connector. The disclosed coupler and coupler / connector assembly are constructed as described herein to allow secure retention of a first connector while allowing separation after a disconnection event.

[0039] Figure 1 is a system diagram illustrating a tracking system for a coupling device in use according to various aspects of the present disclosure.

[0040] Reference Figure 1, the coupling device 100 allows the infusion of fluids, such as medical fluids, to the patient. The coupling device 100 may include a first connector 102 and a second connector 120. The second connector 120 may be connected to the patient's fluid line (e.g., tubing). The first connector 102 may be removably connected to the second connector 120 to deliver the fluid to the second connector 120. The first connector 102 may be a syringe connected to the patient or including a fluid to be delivered to the patient. The second connector 120 may be a needleless fluid connector (NFC) configured to receive and be connected to the first connector 102. When the first connector 102 is connected to the second connector 120, the fluid may flow from the first connector 102 to the second connector 120 and flow to the patient via a portion of the tubing. In some embodiments, the fluid flows from the first connector 102 to the second connector 120 and then flows to the delivery line that connects the patient to the fluid control device 200. For example, the delivery line may be connected to the patient via a catheter at one end and connected to the fluid control device 200 at the other end. The delivery line may include a Y-connector coupled to the second connector 120 to allow fluid to be infused from the first connector 102 via the second connector 120 into the delivery line.

[0041] Fluid control device 200 can be configured to control the fluid flow in the delivery line. In some embodiments, fluid control device 200 is a pump configured to control the fluid flow to the patient. For example, fluid control device 200 may include a fluid source 204, which may be connected to the patient via delivery line 206. Delivery line 206 may connect fluid source 204 to the patient and may include one or more branches. In some embodiments, one of the branches is connected to coupling device 100 (e.g., second connector 120). In some embodiments, first connector 102 may be connected to a fluid source, which is connected to fluid control device 200 or is disposed in the fluid control device.

[0042] The fluid control device 200 may include a tracking device 202. The tracking device 202 may include a reading device and may be configured to communicate with a transmitter (e.g., a wireless transmitter 150) disposed on or coupled to the coupling device 100. In some embodiments, the tracking device 202 is configured to monitor and track / count state changes of the transmitter 150. For example, the tracking device 202 may communicate with the transmitter 150 and may count state changes of the transmitter (e.g., blocked, unblocked). The tracking device 202 may be configured to monitor the usage of the coupling device 100. The usage of the coupling device 100 may include the number of times the coupling device 100 has been moved from an uncoupled position to a coupled position.

[0043] The transition of the coupling device 100 from the uncoupled position to the coupled position may result in a change in state of the transmitter 150. In some embodiments, the transition of the coupling device 100 is due to an actuation of the coupling device 100 (e.g., the coupling of the first connector 102 to the second connector 120). The use of the coupling device 100 (such as the second connector 120) beyond the shelf life may cause the coupling device 100 to malfunction, resulting in infection, clogging, disconnection, or other problems with the coupling device 100. The usage may be tracked starting from the first use of the coupling device 100, so that the total number of uses of the coupling device 100 is tracked and counted by the tracking device 202.

[0044] In some embodiments, a change in state of the transmitter 150 of the coupling device 100 corresponds to a change in configuration of the coupling device 100. For example, a change in state of the transmitter 150 of the coupling device 100 from an uncoupled configuration to a coupled configuration may cause a change in state of the transmitter 150 of the coupling device 100. The tracking device 202 may be configured to send an alarm or indication when the count of changes in state of the transmitter 150 exceeds a predetermined threshold. For example, when the tracking device 202 determines that the number of changes in state of the transmitter 150 exceeds a predetermined threshold, the tracking device 202 may send an alarm, indication, or notification to inform the medical professional that the shelf life of the coupling device 100 (e.g., the second connector 120) has expired or that the coupling device 100 has been used a specified number of times.

[0045] In some embodiments, tracking device 202 increments an internal count in response to a particular state change, depending on the state of transmitter 150 when coupling device 100 is in the uncoupled configuration. For example, if transmitter 150 is covered or blocked when coupling device 100 is in the uncoupled configuration, tracking device 202 may track or count state changes only when transmitter 150 transitions from blocked to unblocked. Additionally, if transmitter 150 is not blocked when coupling device 100 is in the uncoupled configuration, tracking device 202 may track or count state changes only when transmitter 150 transitions from unblocked to blocked.

[0046] Once the internal counter reaches a predetermined threshold limit, the tracking device 202 may send an alarm, indication, or notification to alert the medical professional that the coupling device 100 needs to be replaced. Replacement of the coupling device 100 causes replacement of the transmitter 150, thereby resetting the count of the tracking device 202. The predetermined threshold may be 5 uses to 100 uses, 10 uses to 90 uses, 15 uses to 75 uses, 25 uses to 50 uses, or greater than 100 uses.

[0047] In some embodiments, the transmitter 150 is coupled to or disposed on the coupling device 100. For example, the coupling device 100 may include a first connector 102 and a second connector 120, and the transmitter 150 may be disposed on the first connector 102 or the second connector 120. In some embodiments, the transmitter 150 is a wireless transmitter, such as an RFID device. The transmitter 150 may be configured to store information associated with the coupling device 100. For example, the transmitter 150 may store a serial number, a manufacturing date, an expiration date or shelf life, a specified number of actuations of the coupling device 100, a manufacturer, a size, a product type, or any other information associated with the coupling device 100.

[0048] The transmitter 150 may communicate wirelessly with the fluid control device 200 (e.g., the tracking device 202). The transmitter 150 may allow passive communication with the tracking device 202. For example, the transmitter 150 may not require a power source, and the tracking device 202 may transmit radio waves to the transmitter 150 to power the transmitter 150, thereby allowing the transmitter 150 to send a status (blocked or unblocked) to the tracking device 202. In some embodiments, the use (e.g., actuation) of the coupling device 100 causes the transmitter 150 to approach the tracking device 202, so that the transmitter 150 continuously sends a signal to the tracking device 202. The transmitter 150 may be blocked, resulting in the transmitter 150 no longer sending a signal to the tracking device 202. When the transmitter 150 is not blocked, the transmitter 150 can continue to communicate with the tracking device 202. Due to the connection and separation of the first connector 102 and the second connector 120, the transmitter 150 may be blocked or unblocked.

[0049] The tracking device 202 is configured to detect a change in state of the transmitter 150 caused by actuation of the coupling device 100. For example, the coupling device 100 can be configured to block and unblock the transmitter 150 based on the configuration of the coupling device 100. In some embodiments, the coupling device 100 in the coupled configuration causes the transmitter 150 to be unblocked. In other embodiments, the coupling device 100 in the coupled configuration causes the transmitter 150 to be blocked. When the transmitter 150 is blocked, the tracking device 202 can no longer receive signals from the transmitter 150. When the transmitter 150 is unblocked, the tracking device 202 can receive signals from the transmitter 150.

[0050] In some embodiments, tracking device 202 continuously sends signals to transmitter 150, which receives the signals and sends a response signal. The signal from tracking device 202 to transmitter 150 can supply power to transmitter 150, allowing the transmitter to send a response signal. In some embodiments, transmitter 150 is connected to a power source and sends a response signal when receiving a signal from tracking device 202.

[0051] The tracking device 202 can be configured to count changes in the transmitter 150 from blocked to unblocked or from unblocked to blocked to determine each use or actuation of the coupling device 100. For example, each change in state of the transmitter 150 indicates an actuation of the coupling device 100 based on whether the tracking device 202 receives a signal from the transmitter 150. Each actuation of the coupling device 100 increases the count of the tracking device 202, so that the tracking device 202 can count each use of the second connector 102 of the coupling device 100.

[0052] Based on the position of the transmitter 150 and the presence of a blocking element (e.g., shield 130), the tracking device 202 can be configured to track and count only one-way state changes. For example, the tracking device 202 can be configured to track and count only when the transmitter 150 changes from blocked to unblocked, but not from unblocked to blocked. The transmitter 150 can be blocked based on a shield or shield provided on the connection device 100. For example, the first connector 102 and / or the second connector 120 can include a shield or shield (e.g., shield 130) that is configured to block signals to and from the transmitter 150. The shield or shield can cover the transmitter 150, so that the signals to and from the transmitter 150 are blocked. The movement of the shield or shield causes the transmitter 150 to no longer be covered, thereby enabling the transmitter 150 to receive and send signals, such as sending signals to the tracking device 202.

[0053] In some embodiments, when the transmitter 150 is blocked when the coupling device 100 is in the uncoupled configuration, the tracking device 202 only tracks when the transmitter 150 transitions from blocked to unblocked. In other embodiments, when the transmitter 150 is unblocked when the coupling device 100 is in the uncoupled configuration, the tracking device 202 only tracks when the transmitter 150 transitions from unblocked to blocked.

[0054] Figure 2A According to various aspects of the present disclosure Figure 1 A front view of a first embodiment of a tracking system with the coupling device in an uncoupled configuration. Figure 2B According to various aspects of the present disclosure Figure 2A A front view of a tracking system with the coupling device in a coupled configuration.

[0055] refer to Figure 2A-2B, a first embodiment of a coupling device 100 is shown. Coupling device 100 may include a first connector 102 and a second connector 120. The first connector 102 may be removably coupled to the second connector 120. The second connector 120 may be coupled to a tube 160, which may be coupled to a patient. The first connector 102 may include or be coupled to a fluid source, and may be configured to deliver fluid from the fluid source to the tube 160 via the second connector 120. The coupling device 100 may be in an uncoupled configuration ( Figure 2A ), in which the first connector 102 is separated from the second connector 120, and in the coupled configuration ( Figure 2B ), in which the first connector 102 is connected to the second connector 120.

[0056] The first connector 102 can be a syringe and can include a needle 104 and a needle guard 106. The needle guard 106 can be disposed around the needle 104 and can be configured to protect the needle 104. In some embodiments, the needle guard 106 circumferentially surrounds the needle 104. The second connector 120 can include an opening 122 configured to receive the needle 104 during the coupling of the first connector 102 to the second connector 120 (e.g., the coupling device 100 is in a coupled configuration). The second connector 120 can include a body 124 disposed between the tube 160 and the opening 122. The opening 122 can be disposed opposite the tube 160.

[0057] In some embodiments, the second connector 120 includes a shield 130 disposed at least partially around the second connector 120. For example, the shield 130 can be disposed around the opening 122. The shield 130 can include legs 132 and biasing elements 134. The legs 132 extend from the shield 130 away from the tube 160. For example, the legs 132 can be disposed proximate to the opening 122 and can extend away from the shield 130 such that the legs extend away from the tube 160. The shield 130 can be coupled to the second connector 120 via the biasing element 134. The shield 130 can be configured to move axially relative to the second connector 120. For example, the shield 130 can be coupled to the second connector 120 via the biasing element 134 and can be configured to move axially relative to the second connector 120 due to the biasing element 134. The biasing element 134 can be biased in an expanded state such that the shield 130 at least partially surrounds the opening 122. The biasing element 134 can be coupled to the shield 130 and disposed opposite the leg 132. The biasing element 134 can be configured to couple the shield 130 to the body 124 of the first connector 102. In some embodiments, the leg 132 is disposed closer to the opening 122 than the biasing element 134.

[0058] The biasing element 134 can be configured to transition from an expanded state to a compressed state in response to a force. When the biasing element 134 is in the expanded state, the shield 130 can be in an extended state, and when the biasing element 134 is in the compressed state, the shield can be in a compressed state. In the compressed state, the shield 130 can be positioned proximate to the tube 160 and around the body 124. In some embodiments, when the biasing element 134 is in the expanded state, the shield 130 is closer to the opening 122 than when the biasing element 134 is in the compressed state. In addition, when the biasing element 134 is in the expanded state, the shield 130 can be closer to the tube 160 than when the biasing element 134 is in the compressed state.

[0059] The second connector 120 may include a transmitter 150, such that the transmitter 150 is disposed on the second connector 120. In some embodiments, when the shield cover 130 is in the extended state due to the biasing element 134 being in the expanded state, the shield cover 130 covers the transmitter 150. When the shield cover 130 is in the extended state and covers the transmitter 150 ( Figure 2B ), the transmitter 150 is blocked and cannot communicate with the tracking device 202. When the shield 130 is in the compressed state, the transmitter 150 is no longer blocked by the shield 130 and can communicate with the tracking device 202. The movement of the shield 130 from the extended state to the compressed state causes a change in the state of the transmitter 150, which is monitored by the tracking device 202. In some embodiments, the shield 130 is configured to move axially relative to the transmitter 150.

[0060] like Figure 2A As shown, the coupling device 100 can be in an uncoupled configuration such that the first connector 102 is separated from the second connector 120 and the transmitter 150 is blocked by the shield 130. Figure 2B When the first connector 102 is coupled to the second connector 120, the needle guard 106 applies a force to the legs 132, pushing the legs 132 and the shield 130 from the extended state to the compressed state. In addition, securing the needle 104 within the opening 122 causes the needle guard 106 to apply a force to the legs 132, thereby causing the biasing element 134 to transition to a compressed state, which causes the shield 130 to be in a compressed state. Since the first connector 102 is coupled to the second connector 120, the shield 130 is in a compressed state, causing the transmitter 150 to experience a state change from blocked to unblocked and communicate with the tracking device 202. The state change is tracked by the tracking device 202. In some embodiments, the tracking device 202 is configured to track only when the transmitter 150 changes from blocked to unblocked, thereby preventing the tracking and counting of separation events.

[0061] Figure 3A According to various aspects of the present disclosure Figure 1 A front view of a second embodiment of a tracking system wherein the coupling device is in an uncoupled configuration. Figure 3B According to various aspects of the present disclosure Figure 3A A front view of a tracking system with the coupling device in a coupled configuration.

[0062] refer to Figure 3A-3B , showing a second embodiment of the coupling device 100. The coupling device 100 can be in an uncoupled configuration ( Figure 3A ), in which the first connector 102 is separated from the second connector 120, and in the coupled configuration ( Figure 3B ), in which the first connector 102 is connected to the second connector 120.

[0063] The first connector 102 may be a syringe and may include a needle 104, a needle guard 106, and a shield 130. The needle guard 106 may be disposed around the needle 104 and may be configured to protect the needle 104. In some embodiments, the needle guard 106 circumferentially surrounds the needle 104. The shield 130 may be disposed around the needle guard 106 and configured to extend away from the first connector 102. In some embodiments, the shield 130 extends beyond the needle guard 106. The second connector 120 may include an opening 122 configured to receive the needle 104 during the period when the first connector 102 is coupled to the second connector 120 (e.g., the coupling device 100 is in a coupled configuration). The second connector 120 may include a transmitter 150 such that the transmitter 150 is disposed on the second connector 120.

[0064] In some embodiments, the first connector 102 and the second connector 120 ( Figure 3A ) is not connected, resulting in the transmitter 150 being uncovered and unblocked. The connection between the first connector 102 and the second connector 120 causes the shielding cover 130 to cover and block the transmitter 150 ( Figure 3B ). As the first connector 102 is coupled to the second connector 120, the shield 130 covers and blocks the transmitter 150, causing the transmitter 150 to undergo a state change from unblocked to blocked and no longer communicate with the tracking device 202. The state change is tracked by the tracking device 202. In some embodiments, the tracking device 202 is configured to track only when the transmitter 150 changes from unblocked to blocked. In some embodiments, the shield 130 is configured to move axially relative to the transmitter 150.

[0065] Figure 4A According to various aspects of the present disclosure Figure 1 A front view of a third embodiment of a tracking system of FIG. 1 , wherein the coupling device is in an uncoupled configuration. Figure 4BAccording to various aspects of the present disclosure Figure 4A A front view of a tracking system with the coupling device in a coupled configuration.

[0066] refer to Figure 4A-4B , showing a third embodiment of the coupling device 100. The coupling device 100 may include a first connector 102 and a second connector 120. The coupling device 100 may be in an uncoupled configuration ( Figure 4A ), in which the first connector 102 is separated from the second connector 120, and in the coupled configuration ( Figure 4B ), in which the first connector 102 is connected to the second connector 120.

[0067] The first connector 102 can be a syringe and can include a needle 104, a needle guard 106, a body 108, and a shield 130. The needle 104 and the needle guard 106 can extend from the body 108. The needle guard 106 can be disposed around the needle 104 and can be configured to protect the needle 104. In some embodiments, the needle guard 106 circumferentially surrounds the needle 104. The second connector 120 can include an opening 122 configured to receive the needle 104 during the coupling of the first connector 102 to the second connector 120 (e.g., the coupling device 100 is in a coupled configuration). The second connector 120 can include a body 124 disposed between the tube 160 and the opening 122. The opening 122 can be disposed opposite the tube 160.

[0068] In some embodiments, the first connector 102 includes a shield 130 disposed at least partially around the first connector 102. For example, the shield 130 can be disposed around the needle 104 and the needle guard 106. The shield 130 can include legs 132 and biasing elements 134. The legs 132 can be proximate to the needle 104 and can extend from the shield 130. The shield 130 can be coupled to the first connector 102 via the biasing elements 134. The shield 130 can be configured to move axially relative to the first connector 102. For example, the shield 130 can be coupled to the first connector 102 via the biasing elements 134 and can be configured to move axially relative to the first connector 102 due to the biasing elements 134. The biasing elements 134 can be biased in an expanded state so that the shield 130 at least partially surrounds the needle 104 and the needle guard 106. The biasing elements 134 can be coupled to the shield 130 and disposed opposite to the legs 132. The biasing element 134 can be configured to couple the shield 130 to the body 108 of the first connector 102. In some embodiments, the legs 132 are disposed closer to the needle 104 and the needle guard 106 than the biasing element 134.

[0069] The biasing element 134 can be configured to switch from an expanded state to a compressed state in response to a force. When the biasing element 134 is in the expanded state, the shield 130 can be in an extended state, and when the biasing element 134 is in the compressed state, the shield can be in a compressed state. In the compressed state, the shield 130 can be disposed proximate to the needle 104 and around the body 108. In some embodiments, when the biasing element 134 is in the expanded state, the shield 130 is disposed around the needle 104 compared to when the biasing element 134 is in the compressed state.

[0070] The first connector 102 may include a transmitter 150, such that the transmitter 150 is disposed on the first connector 102. In some embodiments, when the shield cover 130 is in the extended state due to the biasing element 134 being in the expanded state, the shield cover 130 covers the transmitter 150. When the shield cover 130 is in the extended state and covers the transmitter 150 ( Figure 4A ), the transmitter 150 is blocked and cannot communicate with the tracking device 202. When the shield 130 is in the compressed state, the transmitter 150 is no longer blocked by the shield 130 and can communicate with the tracking device 202. The movement of the shield 130 from the extended state to the compressed state causes a change in the state of the transmitter 150, which is monitored by the tracking device 202. In some embodiments, the shield 130 is configured to move axially relative to the transmitter 150.

[0071] like Figure 4A As shown, the coupling device 100 can be in an uncoupled configuration such that the first connector 102 is separated from the second connector 120 and the transmitter 150 is blocked by the shield 130. Figure 4B , when the first connector 102 is coupled to the second connector 120, the second connector 120 applies a force to the legs 132, pushing the legs 132 and the shield 130 from the extended state to the compressed state. In addition, securing the needle 104 within the opening 122 causes the second connector 102 to apply a force to the legs 132, causing the biasing element 134 to transition to a compressed state, which causes the shield 130 to be in a compressed state. Since the first connector 102 is coupled to the second connector 120, the shield 130 is in a compressed state, causing the transmitter 150 to experience a state change from blocked to unblocked and communicate with the tracking device 202. The state change is tracked by the tracking device 202. In some embodiments, the tracking device 202 is configured to track only when the transmitter 150 changes from blocked to unblocked, thereby preventing the tracking and counting of separation events.

[0072] Figure 5A According to various aspects of the present disclosure Figure 1 A front view of a fourth embodiment of a tracking system of FIG. 1 , wherein the coupling device is in an uncoupled configuration. Figure 5BAccording to various aspects of the present disclosure Figure 5A A front view of a tracking system with the coupling device in a coupled configuration.

[0073] refer to Figure 5A-5B , showing a fourth embodiment of the coupling device 100. The coupling device 100 can be in an uncoupled configuration ( Figure 5A ), in which the first connector 102 is separated from the second connector 120, and in the coupled configuration ( Figure 5B ), in which the first connector 102 is connected to the second connector 120.

[0074] The first connector 102 may be a syringe and may include a needle 104, a needle guard 106, and a transmitter 150. The needle guard 106 may be disposed around the needle 104 and may be configured to protect the needle 104. In some embodiments, the needle guard 106 circumferentially surrounds the needle 104. The first connector 102 may include the transmitter 150, such that the transmitter 150 is disposed on the first connector 102. The second connector 120 may include an opening 122 configured to receive the needle 104 during the coupling of the first connector 102 to the second connector 120 (e.g., the coupling device 100 is in a coupled configuration). In some embodiments, the second connector 120 includes a shield 130. The shield 130 may be disposed at least partially around the body 124. In some embodiments, the shield 130 is disposed around the opening 122. In some embodiments, the shield 130 is configured to move axially relative to the transmitter 150.

[0075] In some embodiments, the first connector 102 and the second connector 120 ( Figure 5A ) is not connected, resulting in the transmitter 150 being uncovered and unblocked. The connection between the first connector 102 and the second connector 120 causes the shielding cover 130 to cover and block the transmitter 150 ( Figure 5B ). As the first connector 102 is coupled to the second connector 120, the shield 130 covers and blocks the transmitter 150, causing the transmitter 150 to experience a state change from unblocked to blocked and no longer communicate with the tracking device 202. The state change is tracked by the tracking device 202. In some embodiments, the tracking device 202 is configured to track only when the transmitter 150 changes from unblocked to blocked.

[0076] In some embodiments, the present disclosure includes a method for tracking a coupling device. In some embodiments, the method is performed by tracking device 202 and / or fluid control device 200. The method may include detecting a first state of a transmitter 150 that may be coupled to coupling device 100. The first state may be associated with coupling device 100 being in an uncoupled configuration and transmitter 150 being in one of a blocked or unblocked state. For example, coupling device 100 being in an uncoupled configuration may result in coupling device 100 being blocked ( Figure 2A and Figure 4A ) or unblocked ( Figure 3A and Figure 5A ). The method may include detecting a second state of the transmitter 150. The second state may be associated with the coupling device 100 being in the coupled configuration and the transmitter 150 being in a blocked or unblocked state. For example, the coupling device 100 being in the coupled configuration may result in the coupling device 100 being unblocked ( Figure 2B and Figure 4B ) or blocked ( Figure 3B and Figure 5B ). In some embodiments, the second state is different from the first state.

[0077] The method may also include determining a state change of the transmitter 150 when the transmitter 150 transitions from the first state to the second state. The state change of the transmitter 150 may be when the transmitter 150 transitions from blocked to unblocked or from unblocked to blocked. The state change may occur during the coupling of the first connector 102 to the second connector 120 due to the shield 130 blocking or unblocking the transmitter 150. The tracking device 202 may be configured to increase the number of state changes associated with the total number of state changes detected for the transmitter 150. For example, based on the detected state change, the tracking device 202 may increment an internal counter to indicate that there is another state change.

[0078] Based on the state of the transmitter 150 when the coupling device 100 is in the uncoupled configuration, state changes may be tracked based only on specific transitions of the transmitter 150. For example, if the transmitter 150 is covered or blocked when the coupling device 100 is in the uncoupled configuration, the tracking device 202 may track or count state changes only when the transmitter 150 transitions from blocked to unblocked. Additionally, if the transmitter 150 is not blocked when the coupling device 100 is in the uncoupled configuration, the tracking device 202 may track or count state changes only when the transmitter 150 transitions from unblocked to blocked.

[0079] The tracking device 202 may be configured to compare the number of state changes to a predetermined threshold and send a notification if the number of state changes exceeds the predetermined threshold. For example, if the number of state changes counted or tracked by the tracking device 202 exceeds a predetermined threshold, the tracking device 202 may send or generate an alarm, warning, or notification. The predetermined threshold may be associated with the shelf life or life of the coupling device 100 (such as the second connector 120).
