Definitions

  • the invention relates to a monitoring system for monitoring patients with at least one alarm button, with which a patient can indicate to the care staff a care request, and with an alarm unit for alerting the caregiver.
  • Such a monitoring system and method of monitoring is generally known by hospitals or nursing homes. There is an alarm button next to each bed that the patient or nurse can press if needed by a nurse or nurse. There is then an audible or visual alarm in the known monitoring system in a monitoring station or the nurses' room that a patient in room XY needs something. If no nurse is currently available in the nurses' room, it may be that the patient has to wait a long time for someone to take care of him. Particularly unpleasant here is that the patient does not know if his alarm was even registered by a sister and if so, how long it will take until someone comes. In this case, patients repeatedly press the alarm again, which makes it even more difficult for the nurses to process the alarms in the different rooms.
  • the invention has for its object to provide a monitoring system for monitoring patients and a method for monitoring patients, in which the above disadvantages are avoided.
  • this task is solved in a monitoring system in which the monitoring system the patient is assigned a unique by an alarm button identification identifiable alarm button, which is designed to communicate with the alarm unit via a radio network, wherein a patient server for associated storage of an alarm button identifier, a camera identification and associated with patient information and each patient is provided with a plurality of surveillance cameras characterized by the camera identifiers, the alerting unit for alerting the caregiver to reproduce the A / V signal of the surveillance camera on a monitoring screen of a monitoring station formed by the alarm button identifier is assigned to the alarming alarm button associated with the stored camera identification and records the whereabouts of the patient with care request, the alarm tion unit is designed in particular for the additional representation of stored in the patient server the alarming alarm button stored patient information on the monitoring screen.
  • the alarm unit switches the A / V signal of the surveillance camera to the monitoring screen in the nurse's room, which records the location of the alarming alarm button.
  • a nurse in the nurse's room receives both image and sound information from the patient who triggered the alarm immediately after the alarm is triggered. If more than one alarm occurs more or less simultaneously, then this sister can set immediate priorities, which patient can be helped immediately and, if necessary, later.
  • the nurse can talk to the patient via a loudspeaker or a patient monitor with loudspeakers in the vicinity of the patient who has triggered the alarm.
  • the nurse can help the patient from the nurses 'room without leaving the nurses' room. As a result, the working hours of the nurses can be used efficiently and the patient receives the desired help without a long wait.
  • the alerting unit locates the call units of the sisters in the building and then alerts the nurse closest to the patient's room. However, if this nurse does not have time to do so, as she has been assigned by the alert unit to assist another patient, then another nurse nearby will be alerted.
  • the alarm unit automatically alerts the nurse whose call unit identifier is stored in the patient server assigned to the patient or the alarm button identifier of his alarm button.
  • FIG. 1 shows an overview of a part of a hospital in which a monitoring system 1 for monitoring patients is installed. Three patient rooms 2, 3 and 4 are shown, in which patients 5 to 9 are accommodated. In the monitoring system 1, each patient 5 to 9 is assigned at least one alarm button 10 to 14 that can be uniquely identified by an alarm button identifier ATK.
  • These alarm buttons 10 to 14 are designed as a portable alarm button that can be worn on the wrist of the patient as a clock and are integrated via a wireless access point 16 in a wireless network in the building.
  • Such a commercial portable alarm button 15 is available for example under the type designation T301W and in FIG. 3 shown.
  • Each bed of patients 5 to 9 is further assigned a patient screen, based on FIG. 2 is discussed in detail.
  • FIG. 2 shows the bed of the patient 6 with her wrist-worn alarm button 11.
  • the bed opposite a patient screen 17 is mounted, which has a speaker 18 and a microphone 19, and on which a surveillance camera 20 is mounted.
  • the bed is also assigned a fixed alarm button 21, in addition to the Bed is attached.
  • This fixed alarm button 21, the surveillance camera 20 is assigned permanently, which is why a camera ID KK the surveillance camera 20 is stored in a patient server 22 of the alarm button identifier ATK associated with the alarm button 21, which is discussed in more detail below.
  • the monitoring system 1 further comprises an alerting unit 23 for alerting the caregiver and an alert location system with which the alerting unit 23 is arranged to locate each alert button in the hospital.
  • the alarm unit 23 is formed by a computer together with appropriate software, which is via the WLAN access point 16 for communicating with other devices located in the wireless network, ie, for example, with the alarm buttons 10 to 14 and 21, is formed.
  • the alarm locating system has antennas mounted at different positions in the hospital, with which the received from the alarm buttons responses, depending on the current location of the alarm button, are received with different signal strength. By measuring and comparing the signal strengths, the current location of the alarming alarm button can be located.
  • Portable alarm buttons 10 to 14 are thus located by the alarm button locating system determines whether the response of the alarm button, for example, with an antenna in the hallway of the hospital in front of room 3 or with an antenna in the hallway of the hospital before room 5 or with an antenna in the toilet of the room 3 is more strongly received.
  • alarm unit 23 selects the monitoring camera which records the current location of the alarm button. A large number of surveillance cameras are installed throughout the hospital for this purpose.
  • a monitoring station 27 is provided, in which the nurse 24 is located and can observe a monitoring screen 28 and communicate with a microphone and headphones 29 with the patient.
  • Each nurse 24 to 26 also carries a portable in the wireless network and locked by a call unit identifier REK uniquely identifiable call unit 30 to 32 with it. With the Calling unit 30 to 32, an audible and / or visual alarm to the respective nurse 24 to 26 are delivered.
  • the call units 30 to 32 can either indicate in which room to which patient the nurse is to go or it can also communicate with the call unit (text, as in a pager, or in a configuration stage a speech connection) with the nurse 24 in the monitoring station 27 or be set up with a patient, which is discussed in more detail below.
  • the monitoring system 1 further has a call unit locating system, which is designed to locate the current position of the call units 30 to 32.
  • the call unit locating system is in this case realized in the same way as the alarm locating system, whereby the person skilled in the art is aware of other possibilities for realizing a locating system for alarm buttons and call units.
  • the following additional information is stored for processing alarms of the alarm buttons 10 to 14 for the alarm button identifications ATK, as is shown by way of example in a table 33 of FIG. 4 is shown.
  • alarm button identifications ATK and call unit IDs REK the reference numerals of the alarm buttons and call units are shown here by way of example FIG. 1 entered in Table 33.
  • the following information is stored in the patient server 22 for the patient 5 in the room 2 with the name Mr. Maier.
  • the portable alarm button 10 and a next to the bed of Mr. Maier fixed alarm button 34 have been assigned to him during admission to the hospital and, since Mr. Maier is usually cared for by the nurse 25, the call unit identifier REK was also assigned to their call unit 31 associated.
  • patient information PI the medical history of Mr. Maier can be stored in the patient server 22, for example, that Mr. Maier is allergic to penicillin.
  • the camera ID KK of a surveillance camera 35 opposite the bed of Mr. Maier was stored in the fixed alarm button 34 next to the bed of Mr. Maier and thus Mr. Maier.
  • Mr. Maier wakes up at 2 o'clock in the morning and is disoriented because he does not find his glasses on the bedside table.
  • the nurse 24 is located in the monitoring station 27 and the nurse 25, who usually cared for Mr. Maier, in the rest room. Mr. Maier pushes his portable alarm button 10 to get help because he wants to drink but sees nothing.
  • the radio alarm is located and via the WLAN access point 16, the alarm is forwarded by the alerting unit 23 to the monitoring station 27.
  • the alerting unit 23 outputs the A / V signal from the surveillance camera 35 to Mr. Maier's bed to the monitor screen 28.
  • the nurse 24 sees Mr.
  • the alarm button location system would in this case be formed by the alerting unit 23, which reads out the associated stored alarm button identifier ATK and camera identification KK from the patient server 22.
  • alerting of the caregiver by the alerting unit 23 has been performed by the nurse 24 having received the live image and the live sound of the patient displayed on the monitor screen 28 which has just set an alarm. If the nurse 24 does not respond to this and does not disable the alarm within a certain period of time, then the alerting unit 23 additionally activates the nurse call unit enrolled in the patient server 22 for the patient. In addition or instead, the alerting unit 23 may also alert the pager unit to the nurse who is currently in the vicinity of the alarming patient. This ensures that even if the monitoring station 27 is not occupied for a moment or is working on the processing of other alarms, the patient quickly receives help from another nurse. When one of the alarmed nurses has time, she disables the alarm and can talk to the patient about the call unit and then decide whether to go to the patient or remotely solve the problem.
  • log data for each individual alarm is stored in the patient server 22.
  • log data for each individual alarm is stored in the patient server 22.
  • both statistical quality data can be determined via the care personnel and, if necessary, each individual alerting case can be reconstructed in detail.
  • alarm sensors may be provided: smoke sensor; Fire sensor; Fall sensor, for detecting a patient fall from a bed; Noise sensor; Vital sensor of a patient.
  • smoke sensor smoke sensor
  • Fire sensor Fire sensor
  • Fall sensor for detecting a patient fall from a bed
  • Noise sensor for detecting a patient fall from a bed
  • Vital sensor vital sensor of a patient.
  • a mobile care trolley 36 as a mobile monitoring station or data interrogation station into the monitoring system 1. This allows a nurse to perform some of the tasks of the monitoring station at any location in the hospital, or simply to review current alarms and, if necessary, to process them immediately.
  • the alerting unit 23 is configured to display patient information PI stored in the patient server 22 to the alarming alarm button on the monitoring screen 28.
  • nurse 24 may immediately see the name of the alarming patient, as well as relevant portions of the patient's history or the cause of previous patient alerts, when deciding how best to help the patient.
  • Radio network could be provided for connecting the devices of the monitoring system 1.
  • one or more stationary alarm buttons could be provided in each room, which would also be integrated into the radio network.
  • Stationary alarm buttons can be one or more
  • Surveillance cameras are assigned permanently, whereas portable alarm buttons in the patient server 22 are usually associated with no surveillance cameras. However, one could associate with a portable alarm button that surveillance camera which records the location where the patient usually resides.
  • the monitoring system according to the invention can also have one or more of the functionalities described below:
  • the locating system can monitor dementia / high-risk patients and identify outliers so that they do not have to search for them in the "forest” by means of police / fire departments. Certain areas in the building plan can be defined as locked, which causes an alarm when entering (for example, leaving the building -> alarm, entering the basement -> alarm).
  • an access point with a mobile power supply and a laptop would be configured accordingly and with a location module sufficient to search for the WLAN range of patients ( ⁇ up to 500m outdoors).
  • Each floor of each building used in the surveillance system is digitized to 3D using a 2D plan.
  • Surveillance cameras, alarm buttons and monitoring stations or support points are then drawn on this 3D plan (in near real-time with localization).
  • the monitored surveillance camera is enlarged as a symbol and a real-time image is displayed, and in addition to the other functionalities, the way to the alarm button / patient from the current base / location displayed.
  • all localization participants are drawn (patients with arm buttons, sisters, etc.).
  • Positioning rules can expand the logic of the alarm unit freely, that is, for example, an alarm deactivation can only be made possible by the fact that a sisters button is in close proximity to the alarm-triggering alarm button. The alarm can then be deactivated by simultaneously pressing the nurse and alarm button. Also, notification rules can be defined to automatically forward the alert to nurse call units that are near the alarm when the service is unoccupied. On the call unit of the sisters can then be displayed via text from which room or from which patient the alarm came. Likewise, temporal location rules may be used, meaning, for example, that if a patient is on a toilet in the stairwell or on the stairs for longer than 60 minutes, an alarm may be sounded.
  • the surveillance camera When not in use, the surveillance camera always sets itself to a home position, in which it monitors the patient in bed for movement and can detect a bed crash (day and night).
  • the surveillance camera may also loop through multiple positions and detect movement (e.g., leaving the room).
  • the nurses can reach these people in need of care via the Internet in the operations center (this can, for example, guide the patient to measuring blood pressure).
  • alarms with images can be transmitted to the operations center and false alarms can be avoided much more frequently (false alarm here means car journey and personnel costs ⁇ 30-90 minutes). All the functions described above in terms of the monitoring system in a hospital are also applicable to mobile care.
  • relatives can establish an audio / video connection with the monitoring station via their PC and ask them whether they can be switched through to their relatives or to the patient.
  • Activation of communication via the monitoring station can also take place at specific times (individually per patient). This greatly improves the quality of life for those in need of care as contact with family members is made regardless of the local distance.
  • Applications to self-dependent relatives who are not capable of operating Skype and similar services is also conceivable.
  • the monitoring system constantly monitors all "connected” components continuously. This means that in case of failure of, for example, an alarm button an alarm with the information of the inaccessibility and representation of possible causes (defect, battery, outliers) is triggered. It also ensures that all components are 100% operational and avoids false positives and system failures in operational situations.
  • the paths of the staff are also evaluable and identifiable. This could make an optimization of the processes.
  • the monitoring system is suitable both for monitoring patients in one or more buildings of a hospital or nursing home, and for monitoring patients or persons in need of care in their home environment.
  • the surveillance system according to the invention could also be used in security-related facilities, such as prisons for monitoring and care of prisoners.
  • the arbitrary expandability of the monitoring system can be combined with e.g. 100 surveillance cameras and more or with any number of alarm buttons brings great benefits.
