Definitions

  • Personal safety devices may be used request help in an emergency, such as a medical emergency.
  • Personal safety devices may be used in hospitals, care homes, in the context of home care, or in other situations where the risk of a medical emergency is high.
  • a personal safety device may be carried by a person, such as a patient or an elderly person, who at risk of the medical emergency.
  • a personal safety device may also be carried by someone caring for the person at risk, such as a nurse or a caregiver.
  • the latter group may also use personal safety devices to improve their own safety, such as in the case of a patient exhibiting violent behaviour towards them.
  • a personal safety device 116 to be tested has a device identifier and comprises an alarm button 118, and may comprise a further button 120, and a visual label 122.
  • the mobile testing device 100 comprises a user interface, optionally including a graphical user interface 104.
  • the user interface may be configured to display a graphical representation 106 of the personal safety device 116, a graphical representation 108 of the alarm button, and/or a graphical representation 110 of the further button.
  • the mobile testing device receives alarm messages from the personal safety device over a direct radio link 114. Connections from the personal safety device and the mobile testing device to the server are also illustrated.
  • a method for testing a personal safety device comprises: acquiring 302, by a mobile testing device, a device identifier from the personal safety device; selecting 304, by the mobile testing device, the personal safety device for testing; sending 306, by the mobile testing device to a server configured to receive alarm messages from the personal safety device, a message indicating a test mode for testing the personal safety device, the message disabling alarming for the personal safety device at the server; receiving 308, by the mobile testing device during the testing, an alarm message from the personal safety device over a direct radio link between the mobile testing device and the personal safety device, wherein the alarm message from the personal safety device indicates depression of an alarm button of the personal safety device; and in response to receiving the alarm message, indicating 310 an alarm condition on a user interface of the mobile testing device.
  • the method starts at 300 and ends at 316. All of the operations are not strictly in chronological order in FIG. 3 , and some of the operations may be performed simultaneously or in an order differing from the given ones. Other functions may also be executed between the operations or within the operations and other data exchanged between the operations. Some of the operations or part of the operations may also be left out or replaced by a corresponding operation or part of the operation. It should be noted that no special order of operations is required, except where necessary due to the logical requirements for the processing order.
  • the depression of the alarm button serves as the means for triggering the alarm or for the testing described herein
  • technical means other than the button can be considered to stay within the equivalence.
  • a lever switch or a rotary switch or even a touch-sensitive pad can be implemented as an alarm switch but, conventionally, the button can be considered as the best mechanism for triggering the alarm.
  • the mobile testing device 200 may perform the method with respect to any one or more of the personal safety devices 206, 208, 210, 212.
  • the personal safety system comprises a plurality of mobile testing devices
  • any one of the mobile testing devices 200, 202 may perform testing of any one of the personal safety devices.
  • a nurse may be able to use his/her mobile device to test an alarm function of a patient's (or another person's) personal safety device.
  • the mobile testing device does not necessarily forward alarm message(s) from the tested personal safety device to the server in case of a real alarm situation.
  • a mobile testing device 200, 202 may be configured to only perform testing of personal safety devices associated with the mobile testing device. In such a case, the mobile testing device may forward the alarm message(s) received from the personal safety device to the server 124 in case of the real alarm situation and disable the forwarding during the testing.
  • personal safety devices 206, 208 may be associated with mobile testing device 200
  • personal safety devices 210, 212 may be associated with mobile testing device 202.
  • testing specifically personal safety device 206 with mobile testing device 200 is often used as an example to highlight specific features of the following embodiments.
  • the device ID may be a fixed-length or variable length code comprising numbers and/or letters and/or other characters, and it may comprise or correspond to a serial number of the personal safety device.
  • the device ID may be comprised in the personal safety device.
  • the device ID may be in a human-readable format to be acquired from the personal safety device by a user of the personal safety device. Alternatively or additionally, the device ID may be comprised in the personal safety device in a machine-readable format.
  • the alarm message may comprise the device identifier of the personal safety device.
  • the alarm message may also comprise other information, such as location information of the personal safety device, provided with an indoor or outdoor positioning system, for example.
  • Responders such as an emergency responder or a nurse may acknowledge the alarm and proceed to help the user of the personal safety device.
  • the alarm messages may be at least partially automatically processed by the server before alerting a responder.
  • the alarm messages may indicate a serious or life-threatening condition or emergency.
  • details of the emergency are often not available for including in the alarm message, as the alarm message may be sent simply by pressing the alarm button 118 of the personal safety device 116.
  • all alarm messages may need to be treated with the same level of concern - with the expectation that the holder of the personal safety device may be in life-threatening danger.
  • a policy may exist for all alarm messages received at the server stating that they may need to be responded to within a specific time, or with a certain procedure. A false alarm may therefore result in a great deal of unnecessary work for the responders, and they may not be able to react to real alarms while handling the false alarm.
  • the mobile testing device 100, 200 sends a message that indicates a test mode of the personal safety device 106, 206 to the server 124, 224.
  • the message may comprise the device ID of the personal safety device.
  • the message disables alarming for the personal safety device at the server. If the user of the personal safety device uses the personal safety device to test the requesting of help or triggering an alarm while in the test mode, it may be ignored by the server.
  • the server may also acknowledge the alarm message, but as alarming for the personal safety device is disabled, the responders may not be alerted. As alarms generated in the context of the test mode do not result in alarming at the server, the responders are not burdened by such false alarms.
  • the mobile testing device Upon receiving the alarm message, the mobile testing device indicates an alarm condition on a user interface of the mobile testing device.
  • the user interface may comprise a display or a graphical user interface 104, or a speaker, for example, and the indicating may comprise displaying a message or an image on the graphical user interface, or playing a sound on the speaker.
  • the indicating may provide information to the user that the personal safety device and its alarm button 118 are functioning correctly.
  • a stationary testing station is provided to the users of the personal safety devices.
  • the testing station is at a specific location, such as in one of the rooms of a hospital, and the users must travel to the testing station to test their personal safety devices. False alarms may be avoided e. g. by ignoring requests generated by the personal safety devices in the vicinity of the testing station, i.e. when the testing is carried out at the testing station.
  • the approach has many limitations, especially when the users of the personal safety devices are distributed over a large area, or simply reside far from the testing station.
  • the advantages of the solution include the ability of the user to test their personal safety device using the mobile testing device regardless of time or location.
  • the mobile testing device may be portable and thus carried by the user to any location.
  • the user may not be bound to a stationary testing station, but instead may carry the mobile testing device with them.
  • Each user having a personal safety device may have their own mobile testing device.
  • the user may test their personal safety device at any time they wish to do so.
  • a smartphone or similar may also act as the mobile testing device and perform the method of FIG. 3 and related embodiments for testing the personal safety device.
  • the method may also be implemented as an application, such as a smartphone application, which may be readily accessible to all users who already have a smartphone. Testing of the personal safety devices may therefore be easier and better accessible to users of the personal safety devices.
  • FIG. 4 illustrates embodiments related to acquiring the device ID.
  • the device ID may be comprised in a machine-readable label of the personal safety device.
  • the mobile testing device comprises a camera 112, illustrated in FIG. 1 , and the acquiring comprises scanning 400, with the camera, a visual label 122 of the personal safety device to obtain the device identifier.
  • the visual label may be both human- and machine-readable or comprise both a human-readable part and a machine-readable part, which may or may not be overlapping, allowing for both the human user and the mobile testing device to identify the correct personal safety device for testing.
  • FIG. 5 illustrates embodiments related to acquiring the device ID, and selecting the personal safety device for testing.
  • the acquiring of the device identifier comprises receiving 500 the device identifier in a radio signal continuously or periodically transmitted by the personal safety device.
  • the radio signal may be periodically transmitted in a regular or irregular manner.
  • the radio signal may be received via the same direct radio link 114 as the alarm message.
  • the radio signal may be a Bluetooth signal.
  • the personal safety device may transmit the radio signal continuously, or periodically, possibly at certain intervals.
  • the mobile testing device may receive the radio signal continuously, or it may receive the radio signal periodically.
  • the receiving of the radio signal may also be triggered by an event, such as a user interaction on the user interface of the mobile testing device.
  • the acquiring by receiving the radio signal may also not require any user actions, as the mobile testing device may receive the device ID from the personal safety device as long as it is within range of the radio signal transmitted by the personal safety device.
  • the RSSI value may also indicate a proximity of the personal safety device to the mobile testing device.
  • a first RSSI value may indicate a close proximity of the personal safety device to the mobile testing device. The close proximity may refer to a distance of about 0.5 centimetres (cm) between the personal safety device and the mobile testing device, for example.
  • a second RSSI value that is lower that the first RSSI value may indicate that the personal safety device and the mobile testing device are further away from each other, such as that they are 1 metre apart.
  • the predetermined RSSI threshold may correspond to the first RSSI value, or to the second RSSI value, or to another RSSI value.
  • the predetermined RSSI threshold may correspond to a RSSI value that indicates a very close proximity of the personal safety device to the mobile testing device, such as a distance of about 0.1 cm between the personal safety device and the mobile testing device.
  • the mobile testing device may be configured to select the personal safety device for testing based on the proximity of the personal safety device to the mobile testing device, or if the personal safety device is in very close proximity of the mobile testing device.
  • the proximity may be determined based on the RSSI value as described above.
  • the very close proximity may in practice correspond to the personal safety device and the mobile testing device touching or at least nearly touching each other.
  • FIG. 6 also illustrates an embodiment wherein the selecting further comprises receiving 602 a user input via the user interface to select the personal safety device for testing.
  • the user interface 102 may comprise a touch screen, touch pad, button, microphone, and/or other means for receiving the user input. The user is thus able to affect the selecting; to pick the personal safety device for testing, or to confirm a selection made by the mobile testing device.
  • the mobile testing device may also present an option to abort the selecting to the user to account for the possibility that an incorrect personal safety device is about to be selected for testing.
  • the user interface may be configured to display a graphical representation 106 of the personal safety device, as illustrated in FIG. 1 .
  • the user interface is configured to display a graphical representation 108 of the alarm button, and said indicating the alarm condition comprises altering 312 the graphical representation of the alarm button.
  • the graphical representation 108 of the alarm button may be filled in with a red colour.
  • the alarm condition may be indicated by altering the colour of the graphical representation 108 of the alarm button from red to green, for example. The indicating and altering may occur in real-time or almost real-time with the receiving of the alarm message.
  • the user may be provided with rapid testing results that are easy to understand because of the altering of the graphical representation of the alarm button. Ease of understanding is advantageous in challenging conditions, especially when the user is of a patient with a lowered mental capacity, or a nurse working in a high-stress environment, for example.
  • the personal safety device may comprise a further button 120.
  • the further button may be configured for other purposes than for sending alarm messages, such to cancel a previously sent alarm message.
  • the further button may operate in a similar way as the alarm button in that a button press message may be sent upon depression of the further button.
  • the further button 120 is an alarm button that triggers a low-priority alarm or a request for attention. For example, it may be linked to a call for assistance from medical staff or from a colleague. In some cases, the further button may have no function configured thereto.
  • the user interface is configured to display a graphical representation of the further button, and said indicating the button press comprises altering 704 the graphical representation of the further button.
  • altering the graphical representation of the further button helps distinguish the indicating 702 of the button press from the indicating 310 of the alarm condition.
  • the above embodiments may also extended for one or more further buttons, or other user input element(s) that are comprised in the personal safety device.
  • the personal safety device may also comprise a plurality of alarm buttons, each of which may be tested according to the above embodiments.
  • the test mode may be ended to resume normal operation of the personal safety device.
  • the method further comprises: sending 314, by the mobile testing device to the server, a message indicating an end of the test mode of the personal safety device, the message enabling alarming for the personal safety device at the server.
  • the sending 314 may be triggered by a user input or interaction on the user interface. Alternatively or additionally, the sending may be triggered by a timer.
  • the mobile testing device may be configured to start the timer to measure a time beginning from the acquiring, selecting, sending, receiving, indicating, or another point in time at a beginning of the testing. When the time exceeds or is above a predetermined testing time threshold, the message indicating the end of the test mode may be sent.
  • the predetermined testing time threshold may be 5 minutes, for example. This way, the test mode may be ended even if the user forgets to do so, and normal operation of the personal safety device may be resumed.
  • a mobile testing device 100 for testing a personal safety device 116 comprises means for: acquiring a device identifier from the personal safety device; selecting the personal safety device for testing; sending, to a server 124 configured to receive alarm messages from the personal safety device, a message indicating a test mode for testing the personal safety device, the message disabling alarming for the personal safety device at the server; receiving, during the testing, an alarm message from the personal safety device over a direct radio link 114 between the mobile testing device and the personal safety device, wherein the alarm message from the personal safety device indicates depression of an alarm button 118 of the personal safety device; and in response to receiving the alarm message, indicating an alarm condition on a user interface 102 of the mobile testing device.
