Figure 11 The caregiver label 42 includes a body 14 having a front cover 50 and a rear cover 52. The front cover 50 and the rear cover 52 include mating edges 54, 56 configured to snap-fit ​​or form an interference fit to couple the front cover 50 and the rear cover 52 to each other. The front cover 50 and the rear cover 52 are coupled together to define an interior 60 of the caregiver label 42, which accommodates various components.

[0029] The rear cover 52 includes a support 62 extending toward the front cover 50 to assist in positioning and arranging various components within the interior 60 of the caregiver tag 42. The caregiver tag 42 includes a circuit board 64 or circuit board assembly disposed within the interior 60, which may be configured as one or more circuits or printed circuit boards (PCBs). In a PCB example, the printed circuit board may be flexible or rigid. The interior 60 of the caregiver tag 42 also houses a power source 66, which is generally configured as a rechargeable battery. The rechargeable battery is coupled to the circuit board 64. The caregiver tag 42 includes a charging assembly 68 operatively coupled to a charging port 70. The charging assembly 68 is coupled to the charging port 70 and the power source 66 to provide power and charge the power source 66. Various components within the interior 60 of the caregiver tag 42 are coupled via a plurality of coupling members 72, which may be screws, self-tapping screws, bolts, or other fasteners.

[0030] The caregiver tag 42 includes a transmitter 74 for transmitting information to the positioning system 10, as described herein. The transmitter 74 may be configured as a near-field communication (NFC) antenna. Other configurations of the transmitter 74 may be utilized without departing from the teachings herein.

[0031] Still refer to Figure 1 and Figure 2 The front cover 50 is selectively coupled to the rear cover 52 to enclose the various components within the interior 60. In some respects, the front cover 50 and the rear cover 52 may be coupled to each other via an adhesive 76. Additionally or alternatively, a label 78 may be included on the outer surface of the rear cover 52. The label 78 may include various information regarding the caregiver label 42, the medical facility 40, the caregiver, etc. Furthermore, the label 78 may include identifiers, such as barcodes, that can be scanned to obtain additional information.

[0032] The caregiver tag 42 includes a first button 16 on the front or top of the body 14 and a second button 18 on the side of the body 14. The first button 16 may also be referred to as the front button 80, and the second button 18 may also be referred to as the side button 82. In the example shown, buttons 80 and 82 are mechanical buttons that can be pressed by a caregiver. However, it is also conceivable to use other optional features such as switches, knobs, or touch-sensitive features to provide input to the caregiver tag 42.

[0033] Still refer to Figure 1 and Figure 2 Also refer to Figure 3The caregiver tag 42 includes a control unit 84, which has a circuit board 64, a processor 86, a memory 88, and other control circuitry. Instructions or routines 90 are stored in the memory 88 and can be executed by the processor 86. The control circuitry also includes communication circuitry 92 configured for bidirectional wired or wireless communication. The control unit 84 includes circuitry configured to perform various input or output, control, analysis, and other functions described herein.

[0034] The caregiver tag 42 includes a driver 94, which is communicatively coupled to a control unit 84. The driver 94 is configured to determine or measure the button press type of the front button 80 and the side button 82. Each button 80, 82 can be pressed in a predefined manner, including the number of presses, press length, press pattern, etc. For example, a first button press type can be a single press for a first predefined duration. A second button press type can be a double press (e.g., two presses of the corresponding button 80, 82). Each press of button 80, 82 in a double press can last for a first predefined duration. A third button press type can be a single press of the corresponding button 80, 82 for a second predefined duration, which is longer than the first predefined duration. Thus, each of the front button 80 and the side button 82 can be pressed by a single short press (click-release), two short presses, and a single long press (click-hold). Buttons 80 and 82 can also be pressed in a pattern that, without departing from the teachings of this document, utilizes pressing one or both of the front button 80 and the side button 82 (e.g., side press-front press-side press, etc.).

[0035] The driver 94 is configured to measure button press type using multiple counters 96. Figure 3 In the example, counter 96 includes three front counters 98, 100, and 102 associated with the front button 80 and three side counters 104, 106, and 108 associated with the side buttons 82. Each button press type of each button 80, 82 is counted separately (i.e., by a different counter 96). Counter 96 is configured to adjust in response to a corresponding button press (e.g., a button press type). In some aspects, counter 96 is configured to scroll and count each scroll in response to a corresponding button press type. For example, each counter 96 may scroll between 0 and 10 or between 0 and 16, and then scroll back to 0 after reaching a maximum count. Driver 94 is configured to monitor the scrolling or adjustment of each counter 96 to determine the button press type of each button 80, 82. Driver 94 is configured to transmit the button press type to control unit 84 for further communication outside caregiver tag 42.

[0036] Still refer to Figures 1 to 3The caregiver label 42 includes an indicator light 120 configured to illuminate in response to a button press. The indicator light 120 may be configured to confirm any button press or to confirm the type of button press entered into the caregiver label 42. The indicator light 120 is generally positioned on the front cover 50 near the front button 80. In some respects, the indicator light 120 is configured to illuminate based on a predefined color or predefined pattern and button press type as a basis for pressing buttons 80, 82. The indicator light 120 may include any form of light source, such as fluorescent illumination, light-emitting diodes (LEDs), organic LEDs (OLEDs), polymer LEDs (PLEDs), laser diodes, quantum dot LEDs (QD-LEDs), solid-state illumination, hybrid illumination, or any other similar device. Any other form of illumination may be used in the caregiver label 42 without departing from the teachings herein.

[0037] Furthermore, various types of LEDs are suitable for use as indicator lights 120, including but not limited to top-emitting LEDs, side-emitting LEDs, etc. Additionally, according to various examples, based on existing light color mixing technology, multi-color light sources, such as RGB LEDs using red-blue-green (RGB) LED packages, can be used to generate various desired light output colors from a single light source. The colors and / or patterns associated with each button 80, 82 and each button press can be personalized or adjusted by caregivers or medical institutions 40.

[0038] Still refer to Figure 3 The caregiver tag 42 also includes a motion sensor 124 configured to monitor the movement and motion of the caregiver tag 42. Movement generally indicates that a caregiver is moving around the healthcare facility 40. The sensed movement is configured to be transmitted to the control unit 84, which, as described herein, affects the timing of communication from the caregiver tag 42 to the controller 28 of the positioning system 10. Furthermore, the motion sensor 124 is generally configured to sense movement when a caregiver taps or shakes the caregiver tag 42, and the motion sensor 124 and / or the control unit 84 are configured to distinguish movement around the healthcare facility 40. When the caregiver tag 42 is tapped or shaken, an indicator light 120 can be illuminated in a predefined color or pattern to indicate the charging status of the power supply 66. For example, a green light may indicate a high charge, a yellow light a medium charge, and a red light a low charge.

[0039] The caregiver tag 42 also includes a transmitter 74 configured to selectively communicate with the receiver 26 of the positioning system 10. Typically, the healthcare facility 40 includes multiple receivers located throughout the facility, each receiver 26 defining a receiving area 134. Figure 9Transmitter 74 is configured to selectively communicate with receiver 26 when caregiver tag 42 is located in the corresponding receiving area 134. By using multiple receivers 26, positioning system 10 is configured to track the location of caregiver tag 42 in a predetermined area, typically healthcare facility 40. The receiving areas 134 of receivers 26 generally cover at least a majority of healthcare facility 40.

[0040] Still refer to Figure 3 Also refer to Figures 4 to 6 The positioning system 10 also includes asset tags 44, which are used to monitor and track the location and movement of various devices within the medical facility 40. These devices can be any suitable device, unit, or system within the medical facility 40, such as the vital signs monitor 140. Figure 7 ), 142 beds Figure 7 ), stretchers, intravenous (IV) pumps, lifts, trolleys, etc. Asset tag 44 has a configuration and function similar to nursing staff tag 42 described herein.

[0041] Asset tag 44 includes a front cover 148 and a rear cover 150, which selectively engage with each other to define an interior 152 of asset tag 44. Body 14 includes at least one of a front button 154 (e.g., a first button 16) and a side button 156 (e.g., a second button 18), configured for a caregiver to press to provide input to asset tag 44. Other forms of input reception (e.g., knobs, switches, touch-sensitive features, etc.) may be used without departing from the teachings herein. It is also conceivable that asset tag 44 may include a single button, such as front button 154, without departing from the teachings herein.

[0042] The interior 152 of the asset tag 44 houses various components, including a circuit board 158, which can be configured as one or more circuits, a flexible PCB, or a rigid PCB. The circuit board 158 is coupled to a power source 160 via a cable 162. The power source 160 is generally configured as a battery. Typically, the battery of the asset tag 44 is non-rechargeable but provides power for several years (e.g., approximately five years). The rear cover 150 includes a support 164 extending toward the front cover 148 to support and position the various internal components of the asset tag 44. The various internal components in the asset tag 44 can be coupled to each other via coupling members 166, which can be screws, self-tapping screws, bolts, or other fasteners.

[0043] A support plate 168 is generally positioned between circuit board 158 and power supply 160 to house circuit board 158 and cable 162 within interior 152. Support plate 168 and circuit board 158 are generally coupled to coupling member 166. Support plate 168 may include or be configured as an anti-tamper board operatively coupled to tamper sensor 180. The anti-tamper board may be configured to monitor and / or support tamper sensor 180.

[0044] The front cover 148 and the rear cover 150 are selectively coupled to each other to close the interior 152. In various aspects, the front cover 148 and the rear cover 150 may be coupled to each other via adhesive 170. Additionally or alternatively, the front cover 148 may include a label 172. In some aspects, the asset label 44 may not include the side button 156, but a label 172 may be included on the side of the front cover 148. It is contemplated that the label 172 may be positioned on the side button 156 without departing from the teachings of this disclosure. The label 172 may include various information about the asset label 44, the device to which the asset label 44 is coupled, the medical institution 40, etc. Furthermore, the label 172 may include an identifier, such as a barcode, which can be scanned to obtain additional information.

[0045] Still refer to Figures 3 to 6 The rear cover 150 includes a tamper sensor 180 extending beyond its rear surface 182. The tamper sensor 180 is configured to extend through a defined aperture 184 in a bracket 186, which is coupled to the rear cover 150 via other coupling members. The bracket 186 is coupled to the rear cover 150 to engage a device. The bracket 186 is configured to couple an asset tag 44 to a device or medical device within the medical facility 40. The bracket 186 includes two opposing coupling portions 190, 192 extending beyond the rear cover 150 to receive coupling members for securing the bracket 186 to the device. The coupling portions 190, 192 can project or offset from the remainder of the bracket 186 to form lugs that assist in positioning the asset tag 44 relative to the bracket 186.

[0046] Additionally or alternatively, asset tag 44 may be coupled to the device using a securing member (such as a cable tie or similar feature). The securing member generally extends through opposing slots defined in coupling portions 190, 192, holes defined in coupling portions 190, 192, or combinations thereof.

[0047] In some aspects, asset tag 44 may also include an adhesive pad 198 configured to selectively engage a surface of the device with one or both of the rear cover 150 and the bracket 186. The adhesive pad 198 can assist in coupling asset tag 44 to the device and provide stability to the coupling of asset tag 44 to the device via coupling members and / or fixing members. The adhesive pad 198, coupling members, and / or fixing members are configured to secure asset tag 44 to the device in a manner that prevents unintentional or accidental removal of asset tag 44. Asset tag 44 may be configured to remain active when coupled to the device, which can help prevent theft or unauthorized movement of specific devices.

[0048] Asset tag 44 includes a tamper sensor 180, operatively coupled to a holder 186 and configured to sense when asset tag 44 is coupled to or engaged with the device and when asset tag 44 is disengaged from the device. In some aspects, tamper sensor 180 may be a button or adjustable feature that is pressed when adjacent to the device and released when asset tag 44 is removed from the device. Other configurations of the sensor may be utilized without departing from the teachings herein. Tamper sensor 180 is configured to sense whether asset tag 44 is removed from the device or the timing of such removal, which can help prevent or monitor unauthorized removal of asset tag 44. Once asset tag 44 is placed on the device, tamper sensor 180 is pressed or adjusted, and this is reported to controller 28.

[0049] Asset tag 44 includes a control unit 210, which has a circuit board 158, a processor 212, a memory 214, and other control circuitry. The memory 214 stores instructions or routines 216 that can be executed by the processor 212. The control circuitry may also include communication circuitry 218 configured for bidirectional wired or wireless communication. The control unit 210 includes circuitry configured to perform various input or output, control, analysis, and other functions described herein.

[0050] Asset label 44 includes a front button 154 and a side button 156, both configured to operate in a manner similar to that of caregiver label 42 described herein. Asset label 44 also includes a actuator 230 that monitors adjustments of a plurality of counters 232 to determine or measure the button press type of each of buttons 154, 156. Asset label 44 includes a plurality of counters 234, 236, 238 associated with the front button 154 and a plurality of counters 240, 242, 244 associated with the side button 156. Each counter 232 is configured to adjust or scroll in response to a predefined button press type of one of the front button 154 and side button 156. For example, Figure 3 The asset tag 44 shown is configured for three button press types (e.g., single short press, double short press, single long press) for each of the front button 154 and side button 156, and therefore includes three front counters 234, 236, 238 and three side counters 240, 242, 244. Each counter 232 is configured to scroll to a new number or the next number for the corresponding button press type of the respective button 154, 156, which is transmitted by the driver 230 to the control unit 210.

[0051] Still refer to Figure 3 The asset tag 44 also includes an additional tamper counter 248. The tamper counter 248 is associated with the tamper sensor 180. The tamper counter 248 counts each adjustment to the tamper sensor 180 or each change sensed by the tamper sensor 180. The tamper counter 248 is configured to adjust or roll to a new number or the next number with each change to the tamper sensor 180. The driver 230 is configured to monitor the count of the tamper sensor 180 and transmit any adjustments to the control unit 210. The tamper counter 248 is useful for monitoring the situation when the asset tag 44 is removed from the device.

[0052] Furthermore, even if asset tag 44 is recoupled to the device, tamper counter 248 will adjust in response to removal and recoupling, thereby providing an indication that asset tag 44 has been removed or otherwise tampered with. Additionally or alternatively, asset tag 44 is configured to monitor whether asset tag 44 is removed from the device and the frequency of such removals. It is conceivable that one of the button press types could correspond to a message indicating that asset tag 44 is being removed from the device. Figure 11 In this case, the tamper counter 248 is adjusted, but the control unit 210 may not transmit the removal of asset tag 44 to the controller 28 of the positioning system 10.

[0053] Still refer to Figure 3 Similar to caregiver tag 42, asset tag 44 includes indicator lights 260, which illuminate in response to various functions of asset tag 44, including button presses and the charging status level of power supply 160. Indicator lights 260 can illuminate according to predefined colors or predefined patterns based on which button 154, 156 is pressed and what type of button press.

[0054] Indicator light 260 may include any form of light source, such as fluorescent lighting, LED, OLED, PLED, laser diode, QD-LED, solid-state lighting, hybrid lighting, or any other similar device. Without departing from the teachings herein, any other form of lighting may be utilized in asset label 44. Furthermore, various types of LEDs are suitable for use as indicator light 260, including but not limited to top-emitting LEDs, side-emitting LEDs, etc. Additionally, according to various examples, based on existing light color mixing techniques, multi-color light sources, such as RGB LEDs using red, blue, and green LED packages, can be used to generate various desired light output colors from a single light source.

[0055] Asset tag 44 also includes a motion sensor 262 for monitoring movement and motion of asset tag 44, and thus monitoring the device to which asset tag 44 is coupled. Motion sensor 262 and / or control unit 210 can be configured to distinguish movement of asset tag 44 from shaking or tapping asset tag 44. Shaking or tapping asset tag 44 can cause indicator light 260 to illuminate to indicate the charging level of power supply 160.

[0056] Still refer to Figure 3 As described herein, asset tag 44 also includes transmitter 264 configured to communicate with receiver 26 at various locations within healthcare facility 40. Communication between transmitter 264 and receiver 26 allows positioning system 10 to track the movement of asset tag 44 at various locations within healthcare facility 40.

[0057] Reference Figure 3 and Figure 7 The caregiver tag 42 and asset tag 44 can operate in a substantially similar manner. Compared to the asset tag 44, the caregiver tag 42 can be smaller in size, thereby allowing caregivers to carry or wear the caregiver tag 42. Furthermore, the asset tag 44 may include a bracket 186 for coupling the asset tag 44 to a device, such as a vital signs monitor 140 and a hospital bed 142. Additionally, the caregiver tag 42 is configured to be rechargeable, while the asset tag 44 includes a power supply 160 that is durable for several years.

[0058] Still refer to Figure 3 Also refer to Figure 8 and Figure 9The positioning system 10 includes staff tags 42 and asset tags 44, which are collectively referred to herein as tag 12. Receivers 26 are located throughout the healthcare facility 40 and configured to selectively communicate with each tag 12 when it is located in the corresponding receiving area 134. Receivers 26 may be located in each ward, operating room, imaging room, unit, or area throughout the healthcare facility. Additional receivers 26 may be located at nurse call station 270 or in the corridors of the healthcare facility 40. The receiving area 134 generally covers at least most of the healthcare facility 40.

[0059] The positioning system 10 is generally configured as a real-time location tracking system (RTLS) to track caregivers and devices at various locations within the healthcare facility 40. Both tag 12 and receiver 26 are configured to communicate directly or indirectly with controller 28. The transmitter 24 of tag 12 (generally including transmitters 74, 264) is configured to send tag signals to receivers 26 located at various locations within the healthcare facility 40. Tag signals from tag 12 each include a unique identifier or identification number (ID), which controller 28 associates with the identity of the caregiver or device to which tag 12 has been assigned.

[0060] Each receiver 26 transmits receiver information (such as a receiver ID) and tag information (such as the tag ID of any tag 12 within the reception range of a particular receiver 26) to the controller 28 via the communication network 280. The controller 28 associates the receiver ID with specific locations (e.g., rooms, units, corridors) within the healthcare facility 40. Accordingly, based on the transmissions from each receiver 26, the location of devices or caregivers bearing the associated tag 12 can be monitored. It is also conceivable that, without departing from the teachings of this disclosure, certain patients may wear or carry patient tags 12 to track their movement throughout the healthcare facility 40.

[0061] Tag 12 and receiver 26 can implement various wireless communication technologies to communicate with each other and / or with controller 28 to track the location of caregivers and devices within healthcare facility 40. Exemplary wireless technologies may include radio frequency (RF), Wi-Fi (i.e., 802.11), Bluetooth, Bluetooth Low Energy (BLE), Thread, ultra-wideband (UWB), Z-Wave, Zigbee, infrared (IR), ultrasound, etc.

[0062] Still refer to Figure 8 and Figure 9Receiver 26 is configured to receive wireless signals (i.e., tag signals) from tag 12 and transmit the tag signals and / or tag ID, along with other information, to controller 28 via network infrastructure (such as communication network 280). Controller 28 can then process the information, which generally includes the receiver ID and tag ID, to determine the location of tag 12 within healthcare facility 40. As described herein, controller 28 can also process this information to associate button press type with designated message 30.

[0063] Tag signals or other information from tag 12 can be transmitted from receiver 26 to controller 28. Alternatively, tag signals or other information from tag 12 can be transmitted directly to controller 28, which may or may not utilize communication network 280. Controller 28 has processor 290, memory 292, and other control circuitry. Memory 292 stores instructions or routines 294 that can be executed by processor 290. The control circuitry may include communication circuitry 296 configured for bidirectional wired or wireless communication. Controller 28 includes circuitry configured to perform various input or output, control, analysis, and other functions described herein. Controller 28 may be included in server 300, which may be a local server 300 of medical facility 40 or a remote server 300 of medical facility 40.

[0064] Still refer to Figure 8 and Figure 9 The receiver 26 is configured to communicate with the controller 28 via a communication network 280. Depending on the configuration of the positioning system 10, information can be transmitted unidirectionally from the receiver 26 to the controller 28 or bidirectionally. The communication network 280 may include a combination of wired connections (e.g., Ethernet) and wireless connections (including a wireless communication network 280). The communication network 280 may include various electronic devices that can be configured to communicate via various wired or wireless communication protocols. The communication network 280 may include wireless routers through which remote access devices can communicate with each other and with the server 300.

[0065] The communication network 280 can be implemented via one or more direct or indirect non-layered communication protocols, including but not limited to Bluetooth, Bluetooth Low Energy (BLE), Thread, Ultra Wideband (UWB), Z-Wave, Zigbee, etc. Furthermore, the communication network 280 can be equivalent to a centralized or layered communication network 280, in which one or more devices communicate via a wireless router (e.g., a communication routing controller). Accordingly, the communication network 280 can be implemented via various communication protocols, including but not limited to Global System for Mobile Communications (GSM), General Packet Radio Service, Code Division Multiple Access, Enhanced Data GSM Environment, Fourth Generation (4G) Radio, Fifth Generation (5G) Radio, Wi-Fi, WiMAX, Local Area Network, Ethernet, etc. Through the flexible implementation of the communication network 280, various devices and servers 300 can communicate directly with each other via the wireless communication network 280 or cellular data connections.

[0066] Still refer to Figure 8 The memory 292 of the positioning system 10 may include a database that stores interconnected tag IDs, location IDs, caregiver names, location names, device names, etc., in a table or array. Software (e.g., routine 294) may utilize information transmitted to server 300 via receiver 26 and / or tag 12, as well as information stored in server 300.

[0067] In some respects, receiver 26, tag 12, or both can be configured for bidirectional communication. In such an example, receiver 26 can send signals to tag 12, which communicates directly with controller 28. For example, a location or receiver ID can be sent to tag 12, which then transmits the receiver ID and tag ID to controller 28 for processing.

[0068] Still refer to Figure 8 The information received by controller 28 generally includes ID information and additional button press information determined by the driver 20 (generally including drivers 94, 230) of the corresponding tag 12. The button press information generally includes the button count value determined by the driver 20 of the corresponding tag 12 using counters 96, 232. The button press information can be included in the tag signal or transmitted separately. The positioning system 10 can be programmed to send various messages 30 ( Figure 11 This is interconnected with different button press type information. Message 30 can include updates, information, tasks, actions, requests, etc. Message 30 can be configured (e.g., assigned, adjusted, etc.) at each medical facility 40. It can be accessed through the application interface 302 on the facility device 304. Figure 10 ) Receive messages or assign inputs from the station device 306 or status panel 308 at the nurse call station 270 or from the remote device 310.

[0069] Nurses or administrators at 40 locations within a healthcare facility can assign button press types to certain messages (30). Figure 11 This allows the medical institution 40 to customize the positioning system 10, which facilitates efficient communication via the positioning system 10. The tag 12 can directly or indirectly transmit the button press type to the controller 28, which associates the message 30 with the button press information. Each tag 12 supports button press combinations for individual buttons 16 and 18 (i.e., multiple button press types for the first button 16 and multiple button press types for the second button 18), and can support combinations between two buttons (e.g., first button-second button-first button, second button-first button-second button, first button-first button-second button, etc.).

[0070] The driver 20 of each of the tags 12 is configured to determine or measure the button press type of the first button 16 and the second button 18, which generally include front buttons 80, 154 and side buttons 82, 156, respectively. The driver 20 transmits the button press type (including which button 16, 18 was pressed) to the corresponding control unit 22 (generally including control units 84, 210). The button press type and the pressed button 16, 18 are wirelessly transmitted directly or via receiver 26 to the controller 28 of the positioning system 10. Typically, button press information (including button count values) is transmitted to the controller 28 periodically or at predefined intervals.

[0071] Controller 28 is configured to process button press type information and associate the button press information with messages 30 stored in the memory 292 of controller 28. Controller 28 is configured to determine the button press type based on the received button information. Controller 28 is configured to compare newly received button press information with previously received button information. If the button count value in the newly received button press information is different from the most recently learned button count value in the previous button press information, controller 28 determines that a button press has occurred and determines the button press type. The comparison between the newly received button press information and the previously or most recently learned button press information minimizes or prevents missed button press transmissions that may be caused by signal collisions, interference, attenuation, etc. In some aspects, controller 28 is configured to use the difference between the most recently learned counter value and the newly received counter value to determine the number of times buttons 16, 18 have been pressed since the last successful transmission of button press information (i.e., button press type or button press mode).

[0072] Refer to Figure 3 Also refer to Figure 8Each tag 12 includes motion sensors 124 and 262, collectively referred to as motion sensors 314. Each tag 12 can adjust its operation in response to sensed motion. For example, when tag 12 is stationary, tag 12 can transmit wireless signals (tag signals) to receiver 26 at a first predetermined time interval. When tag 12 is in motion, tag 12 can transmit tag signals to receiver 26 at a second predetermined time interval, which is shorter than the first predetermined time interval. Accordingly, tag signals are transmitted at a higher frequency when tag 12 is in motion to track the position of tag 12 more efficiently.

[0073] Receiver 26 can immediately and automatically communicate with controller 28 in response to receiving tag signals. Thus, when tag 12 is moving, positioning system 10 can receive information (e.g., receiver ID, tag ID, etc.) from each tag 12 at a faster interval compared to when tag 12 is stationary. This allows positioning system 10 to correlate received information with location and track the movement of tag 12 throughout the medical facility 40. It is also conceivable that the interval at which tag 12 transmits wireless signals can be altered based on the speed of tag 12, resulting in shorter intervals for faster movement.

[0074] The control unit 22 of tag 12 receives information from motion sensor 314. Each control unit 22 is configured to receive sensed motion information from motion sensor 314 and transmit motion changes to controller 28. This motion information may be included in the tag signal or may be transmitted separately. For example, when motion sensor 314 senses that the corresponding tag 12 is moving after being stationary, control unit 22 is configured to communicate with controller 28, transmitting that tag 12 is now in motion. Along with the update that tag 12 is now in motion, control unit 22 transmits the time interval at which tag 12 will transmit wireless signals. Accordingly, tag 12 transmits wireless signals, which are transmitted to receiver 26 at first predefined intervals. Controller 28 is then configured to receive information from receiver 26 at the first predefined intervals and monitor whether updated information is received at each interval.

[0075] When tag 12 stops moving for a predefined time, control unit 22 is configured to communicate with controller 28, transmitting that tag 12 is now stationary and will transmit wireless signals at longer second predefined intervals. Controller 28 is then configured to receive update information about tag 12 from receiver 26 at the second predefined intervals and monitor whether update information is received at each interval. Similar communication and updates can be utilized based on the moving speed of tag 12 without departing from the teachings of this document. In such examples, a change in speed or a speed change within a predefined threshold can trigger updates about the speed of tag 12 and the time interval for those updates.

[0076] The notification sent to controller 28 regarding the adjustment of the time interval for transmitting wireless signals is beneficial for monitoring communication with tag 12 and determining whether alerts regarding missed updates are generated at certain time intervals. Figure 12 For example, if controller 28 is monitoring for updates but does not receive update information within a predefined number of intervals, controller 28 is configured to generate an alert 320 to indicate that tag 12 has not delivered updates and is no longer communicating with receiver 26 and / or controller 28 (e.g., no communication with positioning system 10). Missing communication can be due to a variety of reasons, including theft, power outages, loss of possession, etc., which caregivers can investigate.

[0077] Still refer to Figure 8 Control unit 22 is configured to transmit button press type when communicating with receiver 26 and / or controller 28. In case of missed reception, such as in an elevator or stairwell, control unit 22 is configured to transmit button press information after reconnecting to receiver 26 and / or controller 28 to minimize missed information. Tag 12 is configured to be based on counters 96 and 232 respectively. Figure 3 The button press type is determined by adjusting the position of the positioning system 10 without being connected to the positioning system 10.

[0078] In some respects, the button press information transmitted from tag 12 may include a timestamp. Controller 28 can compare the timestamp of the received button press information with the current time to determine the elapsed time. Notification 32 generated based on message 30 associated with the button press type ( Figure 11 This can include elapsed time. Notifying caregivers of elapsed time helps them prioritize handling different notifications.32

[0079] Tag 12 and / or receiver 26 can be configured to transmit information to controller 28 without acknowledgment in one-way communication. Alternatively, controller 28 can transmit acknowledgment of received information to receiver 26 and / or tag 12. Acknowledgment sent to tag 12 can be transmitted to tag 12 via receiver 26 or directly. Acknowledgment can be indicated to caregivers via corresponding indicator lights 120, 260, for example, by illuminating according to a predefined color or pattern.

[0080] Alternatively, certain types of information can be transmitted to controller 28 multiple times to create redundancy and reduce missed information. Each state change or condition change of tag 12 can be transmitted multiple times. State changes can include motion changes, input-induced deactivation, near-power-down-induced deactivation, etc. When tag 12 needs to be deactivated or turned off, the tag transmits this information to controller 28, and controller 28 stops monitoring and updating at predefined intervals.

[0081] Reference Figure 10An exemplary application interface 302 is shown, comprising a configuration screen 324. The configuration screen 324 includes a table 326, which has a button list 328, a press type list 330, a function list 332 for message 30, and a light list 334. Table 326 shows which button press types of buttons 16 and 18 correspond to message 30 and the lighting types of indicator lights 120 and 260. The information in Table 326 is exemplary only and not intended to be limiting.

[0082] Near each message 30 in the function list 332 is an extension icon 336, which can allow drop-down menus for different messages 30, text boxes for entering messages 30, etc. The medical institution 40 can select a message 30 (e.g., a function) associated with each button press type of each button 16, 18. In this way, the application interface 302 can receive assignment input, where caregivers assign each button 16, 18 and button press type to certain messages 30. Examples of messages 30 may include SOS calls, SOS alerts, cleaning requests, doctor requests, emergency levels, scheduling maintenance, pairing ready mode, on / off, etc. Each message 30 can be a preset message 30, a predefined message message, or information of a predefined type or category.

[0083] Message 30 can be configured and customized by those in the healthcare facility 40, and can be changed. Each message 30 of asset tag 44 can be adjusted separately from the caregiver tag 42. Furthermore, the message 30 for button presses on asset tag 44 can be the same, different, or overlap with those for caregiver tags 42. In some respects, each caregiver tag 42 in the healthcare facility 40 can have the same message 30, and each asset tag 44 in the healthcare facility 40 can have the same message 30. Alternatively, the message 30 can be customized or personalized for each caregiver, each care team, each equipment type, each piece of equipment, etc. Messages can be adjusted, personalized, etc., through application interface 302. Table 326 can be stored in or accessed by controller 28 to associate received button press information with specified message 30.

[0084] Table 326 may also include assignments regarding which application interface 302 displays message 30 or message information, such as on-site device 306, status panel 308 at nurse call station 270, remote device 310, institutional device 304, etc. Furthermore, certain groups of personnel can be assigned to each function or message 30. For example, if message 30 is a call for a doctor, all doctors within medical facility 40 or the unit where tag 12 is located can receive notification 32. If message 30 is a security request, the security team of medical facility 40 can receive notification 32. Additionally, nursing staff at certain locations identified by location system 10 can receive notification 32. Those personnel receiving notification 32 can be configured similarly to the functions associated with each button press type.

[0085] Reference Figure 11 Controller 28 ( Figure 3 The configuration is set to generate notification 32 and / or include message 30 or related message information based on the assigned message 30. For example... Figure 2 As shown, notification 32 is configured to be sent to application interface 302 for viewing by nursing staff, such as... Figure 11 As shown. Notification 32 may include a predefined message 30 or a corresponding information category. Notification 32 may be based on the type of tag 12, the position of tag 12, the elapsed time between button press and reception by controller 28, etc. Notification 32 may also include information about the current position of tag 12, whether tag 12 was in motion when it transmitted button press information from caregiver or when notification 32 was generated. Figure 11 The information shown in Notice 32 is merely illustrative and may include any applicable information without departing from the teachings herein.

[0086] Reference Figure 12 Controller 28 ( Figure 3 The controller monitors signals received from tag 12 to determine location and monitors the situation when no updated or subsequent signals are received within a predefined interval. When no subsequent signals are received within a predefined interval or multiple subsequent intervals, the controller 28 is configured to generate an alert 320 and transmit the alert 320 to the application interface 302, such as... Figure 12 As shown. Alert 320 may include various information, including tag ID, the last position of tag 12, whether tag 12 was in motion before missing the interval, etc. Figure 12 The information shown in Alert 320 is merely illustrative and may include any applicable information without departing from the teachings herein. Healthcare facility 40 may designate and / or configure which personnel receive Alert 320 based on its type, location, etc. A process similar to that for Notification 32 may be used to configure Alert 320 and alert information.

[0087] Now refer to Figure 13 Controller 28 ( Figure 3 The system is configured to generate a mapping screen 340, which is displayed on the application interface 302 to allow visual tracking of tags 12 and messages 30 throughout the medical facility 40. A graphical representation of the floor plan 342 of the medical facility 40 can be displayed. Other levels or floors can be viewed by selecting arrow icons 344. The locations of caregiver tags 42 and asset tags 44 can be indicated on the floor plan 342 via identifiers 346 and 348, respectively. Figure 13 In the example shown, caregiver tag 42 is represented by a first identifier 346 (e.g., a dot), and asset tag 44 is represented by a second identifier 348 (e.g., a triangle). The floor plan 342 can be continuously updated by controller 28 in response to subsequent information from receiver 26 and / or tag 12.

[0088] Furthermore, when a button press message is transmitted from one of the labels 12, the subsequent transmission of message 30 can appear as an indicator 350 on the floor plan 342. The indicator 350 can be positioned near the identifiers 346, 348 associated with the label 12 that transmitted the button press message. The indicator 350 can be general, alerting those viewing the application interface 302 that message 30 has been sent in response to a button press message from the selected label 12. Additionally or alternatively, the selection indicator 350 can display (e.g., using a pop-up graphic, a separate screen, etc.) message 30. In other non-limiting examples of pre-setting or categorizing each message 30, each type of message 30 can be associated with a specific indicator 350, allowing the specific indicator to be displayed near the identifiers 346, 348 of the label 12. Accordingly, the indicator 350 can indicate any message 30 or a specific message 30.

[0089] Reference Figure 14 Also refer to Figures 1 to 13 A method 360 for transmitting a message 30 via a location system includes a step 362 of configuring button presses. Caregivers or users can use an application interface 302 to input message-related input into the location system 10 and assign certain functions or information 30 to each button press type on each button 16, 18 of each type of label 12 within the location system. Caregivers or users can input identification information (e.g., authentication information) to authorize access to modify the information in the message 30. In some respects, administrators of the healthcare facility 40 may have the authority to modify the message 30 throughout the healthcare facility. Alternatively or additionally, the message 30 can be personalized for certain caregivers, and individual caregivers can modify the message 30 for their respective caregiver labels 42.

[0090] Step 364: The caregiver presses one or both of the buttons 16 and 18 on label 12 in a predefined pattern or manner. The selected combination or length of button press corresponds to selection message 30. Step 366: The corresponding actuator 20 measures or determines the button press type and transmits it to the control unit 22 of label 12.

[0091] In step 368, control unit 22 is configured to transmit button press information. The button press information, along with a tag signal, can be transmitted to receiver 26, where the tag 12 is located in the associated receiving area 134, and then transmitted to controller 28. In this example, the button press information is transmitted substantially via a single receiver 26. It is also conceivable to use more than one receiver 26 to transmit button press information. Alternatively, button press information can be transmitted to controller 28 without receiver 26.

[0092] In step 370, the controller 28 can acknowledge receipt of the button press information to the tag 12. For example, the indicator lights 120 and 260 of the corresponding tag 12 can illuminate in response to the acknowledgment. Other visual, tactile, or sensory modes can be used to acknowledge receipt of the button press information. The acknowledgment can be sent directly from the controller 28 to the tag 12, via the communication network 280, or via the receiver 26 to the tag 12.

[0093] In step 372, controller 28 is configured to associate button press information received from tag 12 with configurable message 30. In step 374, controller 28 is configured to generate notification 32 based on message 30 or to include message 30. In step 376, controller 28 is configured to send notification 32 to application interface 302 to be viewed by a caregiver. Messages can be sent to selected personnel based on assignments stored in controller 28. For example, some notifications 32 can be sent to nurses, while others can be sent to technicians. Furthermore, some notifications 32 can be displayed on in-station device 306 or status panel 308, while others can be viewed in electronic medical records or patient profiles available to caregivers. It is understood that steps 362 to 376 of method 360 can be performed in any order, simultaneously, repeatedly, and / or omitted without departing from the teachings herein.

[0094] Reference Figure 15 Also refer to Figures 1 to 14A method 380 for transmitting location information can be performed independently of or in combination with the method 360 described above for transmitting messages 30 via the positioning system 10. This method 380 includes a step 382 of activating tag 12. Tag 12 can be powered on and transmit an activation state to controller 28. If tag 12 is a new tag, it can be placed in authentication mode to determine if tag 12 is correctly installed. In authentication mode, the positioning system 10 does not report information associated with any button presses, but instead provides verification of the received transmission from tag 12. After verification, tag 12 is transitioned from authentication mode to a fully activated state.

[0095] In step 384, tag 12 is configured to communicate with receiver 26. Tag 12 is configured to transmit a tag signal (including at least the tag ID) to any receiver 26 for positioning in the associated receiving area 134. The tag signal may also include button press information. In step 386, receiver 26 transmits the tag ID and receiver ID to controller 28. Furthermore, in step 386, controller 28 associates the receiver ID and tag ID with various stored information (location, caregiver, device, etc.) to determine the location information for selecting tag 12 and the person or device associated with tag 12. Location information is determined in various ways by using information received from more than one receiver 26 (e.g., two to four receivers). Using multiple receivers 26 can provide additional location information. However, it is contemplated that location information can be determined using information from a single receiver 26 without departing from the teachings herein.

[0096] In step 388, motion sensor 314 is configured to sense movement of tag 12. In step 390, based on the sensed movement, tag 12 is configured to communicate with controller 28, transmitting the update time interval for tag 12 to be in motion and for transmitting tag signals to receiver 26 in response to the motion. Thus, controller 28 updates itself when it should receive subsequent information about a particular tag 12. Transmission of tag ID and receiver ID continues at the update time intervals. Furthermore, in response to each subsequent transmission, location information continues to be correlated with stored information and updated in the positioning system.

[0097] Step 392, motion sensor 314 is configured to detect pauses in motion. A pause can be a predefined period during which the tag is considered stationary. Step 394, tag 12 is configured to transmit a stop or pause in motion to controller 28 and an update time for communication with receiver 26. The time interval for transmitting tag signals from stationary tag 12 can be shorter than the time interval for tag 12 in motion.

[0098] Step 396 involves transmitting the location information determined by controller 28 to application interface 302. This location information may be included in notification 32, floor plan 342, or both. This allows for monitoring of the location and movement of tag 12 throughout the healthcare facility. For example, notification 32 may include notification that an asset tag 44 on medical bed 142 has moved from one ward to another. Alternatively, notification 32 may update caregivers that the previously moving asset tag 44 is now stationary. It is understood that steps 382 through 396 of method 380 may be performed in any order, simultaneously, repeatedly, and / or omitted without departing from the teachings herein.

[0099] Reference Figure 16 Also refer to Figures 1 to 15 The method for transmitting location information is similar to 400. Figure 15 Method 380 is shown. Method 400 includes a step of activating the tag 402, a step of transmitting activation 404, and a step of transmitting the tag ID and receiver ID to the controller 28 406. Furthermore, method 400 includes a step of detecting motion 408 and a step of transmitting an updated time interval in response to motion 410. Step 412 may include detecting a pause in motion, and step 414 includes transmitting an updated interval to the controller 28 in response to a standstill.

[0100] In step 416, controller 28 is configured to determine whether tag ID and receiver ID have been received at predefined intervals. Positioning system 10 is programmed to monitor the reception of information from tag 12 at time intervals or any updated or subsequent time intervals in response to sensed motion. Furthermore, in step 416, controller 28 is configured to determine whether tag 12 has missed an interval for transmitting tag signals or a predefined number of intervals. In step 418, controller 28 is configured to generate an alert 320 regarding the missed information. In step 420, alert 320 is transmitted to application interface 302. It will be understood that steps 402 to 420 of method 400 may be performed in any order, simultaneously, repeatedly, and / or omitted without departing from the teachings herein.

[0101] Reference Figures 1 to 16A positioning system 10, equipped with caregiver tags 42 and asset tags 44, is used to monitor the location of each tag 12 and to transmit messages 30 via the tags 12. In addition to location, transmitting additional information and messages 30 can facilitate the rapid and efficient delivery of selected or predefined messages 30 to other caregivers or systems throughout the healthcare facility 40. Caregivers can send messages 30 via the tags 12, such as requesting a doctor, requesting security, or requesting cleaning. The tags 12 are also configured to update a controller 28 based on changes in circumstances or status, and the controller 28 controls the generation of notifications 32 and alerts 320. For example, when the tag 12 is to be powered off or deactivated, the tag 12 will send a deactivation message to the controller 28, so the controller 28 will not generate an alert 320. Furthermore, the tags 12 are configured to communicate at different time intervals in response to sensed motion. The positioning system 10 provides a system for real-time monitoring of the location of caregivers and equipment within the healthcare facility 40 while simultaneously transmitting predefined messages 30 in response to button presses.

[0102] Various advantages can be provided by utilizing the devices and systems disclosed herein. For example, the positioning system 10 can be configured for each medical facility 40 to customize and personalize the messages 30 sent via tag 12. Furthermore, tag 12 can be used to convey multiple messages 30 based on button press type. Additionally, tag 12 is configured to update the positioning system 10 with location (e.g., via tag ID from receiver 26), message information, and motion information. Furthermore, indicator lights 120, 260 can indicate power levels, confirmation from controller 28, and confirmation of button press type. Other benefits or advantages can be achieved and / or obtained.

[0103] Each of the controller 28 and control units 22, 84, 210 of this disclosure may include various types of digital or analog control circuitry, and may include processors 86, 212, 290, microcontrollers, application-specific integrated circuits (ASICs), or other circuitry configured to perform various input or output, control, analysis, or other functions of this disclosure. The memories 88, 214, 292 described herein may be implemented using various volatile and non-volatile memory formats. Routines 90, 216, 294 may include operating instructions that enable the various methods described herein.

[0104] The devices and systems of this disclosure are further summarized in the following paragraphs, and are further described by any or all of the aspects and combinations thereof described herein.

[0105] According to another aspect of this disclosure, a positioning system includes a tag comprising: a body having a first button and a second button; a driver configured to determine a button press type of at least one of the first button and the second button; and a control unit in communication with the driver. The control unit is configured to transmit the button press type determined by the driver. The tag also includes a transmitter in communication with the control unit. At least one receiver is configured to selectively communicate with the transmitter. The controller communicates with the receiver. The controller is configured to: determine the location of the tag within a predefined area based on information from at least one receiver, associate button press types from the tag with messages, and generate a notification to transmit the messages.
