Description

Field of the invention

[0001] The present invention belongs to the technical field of data detection and processing, as well as to the field of communication techniques and systems adapted for use in health care, more precisely to the field of devices for emergency calls. The invention relates to a household emergency call device.

Background of the invention and the technical problem

[0002] Medical insitutions that provide care for patients use various systems to ensure proper management and control of patients is performed. Nurse call is the name for such systems arranged to allow controlling, guarding and alarming intended for use in hospitals, health centres, nursing homes or other facilities, where spaces are guarded. The purpose of nurse call systems is efficient calling of medical personnel into a room, where a patient needs help. Usually the patient in a bed triggers a call of the medical personnel into the room where the patient is located. The call is triggered with a button and a rope. A nurse receives on her unit an alarm and information about the room where the call has been made. At the same time a light or a signal above the door or the bed is turned on. When the nurse comes to the room or the patient who made the call turns off the call with a special button or a switch.

[0003] However, such systems can only be used in hospitals, health centres, nursing homes, etc., as they are not suitable for home use. Namely, elderly and/or ill have to be monitored regularly to prevent any unecessary or unwanted events, such as forgotten medicines and/or medical appointments, or more importantly provide help and/or treatment in case of need or emergency. Elderly are prone to falls, cardiac arrests and other conditions, which require immediate reaction. A timely emergency call from home may save lives, therefore keeping track of elderly or patients is required.

[0004] As people rarely employ personal help, it is desired that the control is provided from a distance. Various emergency call devices (also called Hausnotrufanlage in German) for home use have been developed, but their functions are limited. In essence, these devices have 3 or 4 buttons in case of emergency, as well as a microphone and a loudspeaker for communication with a call centre, hospital, nursing home or any other person in charge. The problem of these devices is that the buttons have to be pressed in order to achieve contact, which cannot be done by the affected person if the person is not near the device, if the person has fallen, etc.

[0005] Therefore, the technical problem, which is solved by the present invention, is design of a device for emergency calls that will upgrade existing devices, solve their disadvantages and thus contribute to more efficient monitoring of patients and/or elderly living in their homes.

Prior art

[0006] Some known devices are based on cameras and subsequently taken video footage of the person, which is not practical or can interfere with the intimacy of the followed person. Such solution is described in documents CN113971869, JP2002041659 and JP2004110222. Some devices make use of sensors instead of cameras, such as the device according to patent application KR20130137976.

[0007] Patent application DE102011004099 relates to a device having signalling equipment supported and/or fastened to the body of a person to be monitored. The signalling equipment includes a sensor system comprising an air pressure sensor and an acceleration sensor for generating and transmitting sensor signals, e.g., air pressure and jerk load, to an evaluation unit. The evaluation unit receives and evaluates the sensor signals for recognizing fall of the person to be monitored.

[0008] Utility model CN216053262 discloses a home-based care rescue system. A detection module is used for detecting heart rate data, blood pressure data, body temperature data and data important for detection of falls to be used by an elderly person living at home. A controller is provided with a memory which is used for storing health record data of the person and comparing the health record data with the body data detected by the detection device. An emergency call device is used for carrying out emergency call when something abnormal is detected by the controller, wherein an alarm device is used for sending out an alarm signal if the emergency call is performed. Monitoring is achieved with cameras and microphones, which are not used for this purpose in the present invention.

[0009] Patent US1 1064339 discloses an emergency event detection and response system that detects an occurrence of an event associated with a user and initiates an emergency response flow. A user may be associated with a wearable device and have in his home a base station and portable or stationary wireless devices containing sensors capable of detecting an emergency event. The emergency event may be detected based on voice or non-voice audio input from the user, data monitoring by the wearable device, base station, and/or portable or stationary wireless device, or by physical button press. Confirmation that the emergency call is initiated is audio based, either by user or by sensing characteristic sounds (for example, a fall, tumbling, "ouch", and similar). Responsive to determining that an emergency event has occurred, the system triggers an emergency response flow by notifying a call center and contacting one or more caregivers associated with the user. Caregivers may access a response system application to receive updates regarding the detected emergency and to contact the user and/or a provider associated with the call center.

Description of the solution to the technical problem

[0010] The present invention addresses the problem of detecting emergency or other situations in which the monitored person needs help and automatically initiating response based on detected situation. The technical problem is solved as defined in the independent claim, wherein the preferred embodiments are defined in dependent claims.

[0013] Further, the device is connectable to an external device such as blood oxygen meter, blood sugar measurement device, device for measuring pressure, heart rate, and similar devices. The connection is achieved via Bluetooth or any other suitable protocol, such as Zigbee. Second connection means may also be provided for connection to internet. Upon detecting abnormalities, the processor is configured to initiate the emergency call and/or call to any other responsible person entered in contacts.

[0014] The device may also be paired with a movement sensor designed as a small box with movement sensors for sensing movement of a person. It is preferably placed under a bed in order to detect if the monitored person has the same lifestyle as before (waking up and going to bed at approximately the same time, intermediate bed time during the day, etc). Such movement sensor is paired with the device according to the invention via communication means and the processor of the device is configured to initiate an SOS call if the sensor did not detect movement for a particular pre-set time, for example from 6 to 16 hours over night or 2 or more during the day, if the lifestyle has significantly changed, etc.

[0015] The device can be connected to SOS buttons or mechanisms installed in bathrooms or toilets and their activation leads to initiating the SOS call.

[0016] The device may be connected to an automatic distributor of pills, wherein the distributor has a plurality of compartments for receiving at least one pill and a cover for covering all compartments with one openable part corresponding to one compartment, so that a user can access the pills, wherein the cover is controlled with a controller, preferably a PCB, arranged to move the cover once a specific date and/or time has been reached, so the user can timely take them. Furthermore, the controller is arranged to detect if the distributor of pills has been placed vertically in order to take the pills out from the dispenser. If not taken in time, the openable part is locked. The cover may be opened by an authorized person to fill the compartments and the controller may be set suitably in agreement with the schedule for taking the pills. The device is arranged to detect upon connection of the automatic distributor of pills if the pills were not taken in time, in order to call the responsible person or to make an emergency call.

[0017] The device according to the invention is also pairable with other external devices, which enable Bluetooth or similar protocol-based connection, said devices being windows, doors, window shuts, lights, audio-video devices and similar. Most notably, connection to doors is preferred, wherein in case of initiated emergency call the device causes the doors to unlock in order to allow the SOS response team free access to the user in need of medical attention. Preferably, the doors are equipped with a Bluetooth door lock, which can be paired with the device, the latter being programmed to unlock the door lock once an emergency call is initiated. This decreases the time needed to get to the user and improves the chances for survival or recovery.

[0018] Displayed initial user interface may be divided to SOS (emergency) call, vitalities, contacts, calendar, and games, with further submenus related to calendar, vitalities, contacts, and games. The SOS call field is the largest and preferably in the centre of the display/touchscreen. The loudspeaker may emit sounds in connection with pressed fields of the display, for example "Calendar" when calendar is pressed (chosen). Games menu enable access to cognitive games such as memory, chess, card games, and association-based games. Contacts menu enable calls to pre-set contacts, such as relatives, friends and caregivers. Vitalities menu allows access to overview of performed measurements relating to heart rate, blood pressure, blood glucose, oxygen saturation, as well as taken medicines in case the device is connected to the pill dispenser. The user interface may also have a menu for caregivers and/or other people interacting with the user, for example cleaning staff, housekeepers, physiotherapists, etc. All additional users interacting with the user of the device can log into the device and document the performed tasks or tasks to be completed next time or in the following days, weeks or months. For example, a caregiver can enter which medication they administered to the user, how much liquid the user drank, which other events and/or states have been observed, etc. This allows caregivers, their superiors and/or user's relatives to check performed activities related to cleaning and other services provided by other personnel. This documentation may be stored on the device and/or the cloud/server, to which the device stores information. All the documentation can be checked remotely by the elderly home or other service organisation.

[0019] The server may be any suitable server, including cloud servers, wherein all protocols and operations of storing, accessing and viewing stored data are achieved and performed in manners known to the person skilled in this art.

[0020] The invention enables efficient monitoring of users, i.e., elderly or patients, and allows prompt emergency calls in case of detected abnormalities. Thus, users still enjoy independence from others without compromising their safety.
