Description

Technical Field

[0001] The present invention relates to the field of information processing technology, and in particular to a method for monitoring home safety of elderly people. Background Art

[0002] The safety of the elderly at home has become a focus of social attention, especially for those over 80 years old. The risk factor of living alone at home has increased sharply compared with the elderly in other age groups. The increase in the risk factor mainly comes from the increase in physiological risk events such as myocardial infarction and cerebral infarction, as well as the increase in behavioral risk events such as sudden falls.

[0003] In order to improve the safety factor of the elderly at home and monitor the health status of the elderly in real time, the existing technology provides a variety of home safety monitoring methods. The common feature of these monitoring methods is to use wearable devices to monitor the physiological indicators of the elderly, such as heart rate, blood pressure, and body temperature. If these indicators are abnormal and a dangerous event is judged based on the abnormal indicators, the family will be notified and medical departments will be sought for help.

[0004] However, the above-mentioned home monitoring method has the following problems:

[0005] 1. The above monitoring method monitors, judges and considers the dangerous events caused by abnormal behavior of the elderly (such as falls).

[0006] 2. Dangerous events are not classified into risk levels, which results in the elderly seeking help from medical departments even when some less urgent dangerous events occur, thereby increasing the burden on medical departments in emergency treatment. In addition, of course, the above method does not include the dangerous event of abnormal behavior of the elderly in the risk level classification.

[0007] 3. The health data reports and evaluations obtained by monitoring the physiological indicators of the elderly are only based on the normal physiological indicators of normal people. Summary of the Invention

[0008] In view of the above technical problems existing in the prior art, an embodiment of the present invention provides a method for monitoring home safety of the elderly.

[0009] To solve the above technical problems, the technical solutions adopted in the embodiments of the present invention are:

[0010] A method for monitoring home safety of elderly people, comprising the following steps:

[0011] Obtaining users' personal information;

[0012] Obtain the user's physiological indicator information and behavioral status information in real time;

[0013] Whether a dangerous event has occurred is determined based on the user's physiological indicator information and behavioral status information obtained in real time. If it is determined that a dangerous event has occurred, help information is sought from the outside world and the dangerous event is recorded. If it is determined that no dangerous event has occurred, the obtained user's physiological indicator information and behavioral status information are compared with preset physiological indicators and normal physiological indicators to obtain the user's health data information.

[0014] Preferably, the dangerous events are divided into first-level emergency dangerous events and second-level emergency dangerous events according to the danger level;

[0015] If a Level 1 emergency event is determined to have occurred, a first help message and first additional information are sent to a medical department to enable the user to obtain emergency treatment from the medical department, and a copy of the first help message is simultaneously sent to the family. The first help message includes a warning message and specific information about the Level 1 emergency event that has occurred, and the first additional information includes the user's personal information and the contact information of the family;

[0016] If it is determined that a level 2 emergency event has occurred, a second request for help message and a second additional information will be sent to the family. The family will determine the handling plan for the level 2 emergency event based on the second request for help message and the second additional information. The second request for help message includes specific information about the level 2 emergency event that has occurred, and the second additional information includes information on the possible consequences of the level 2 emergency event and the contact information of the medical department in the user's living environment.

[0017] Preferably, the behavior status information includes information on whether the user has fallen;

[0018] Judging whether a dangerous event has occurred based on the user's physiological indicator information and behavioral status information obtained in real time includes:

[0019] Setting a first threshold and a second threshold representing a physiological sign, wherein the first threshold is outside a normal range of the physiological indicator, and the second threshold is outside the first threshold;

[0020] If the physiological indicator information obtained in real time exceeds the second threshold, or the physiological indicator information obtained in real time is between the first threshold and the second threshold and the user behavior status information is a fall, it is judged that a level one emergency dangerous event has occurred; if the physiological indicator information obtained in real time is within the first threshold and the user behavior status information is a fall, it is judged that a level two emergency dangerous event has occurred.

[0021] Preferably, the physiological index includes at least a blood pressure index, a heart rate index and a body temperature index, and the first threshold and the second threshold are set based on the heart rate index and the blood pressure index.

[0022] Preferably, the user's personal information includes the user's personal identity information and inherent disease information, and the preset physiological indicators are set based on the user's inherent disease information.

[0023] Preferably, after determining that a dangerous event has occurred and it is a level one emergency dangerous event, the user's location information is obtained. If the user is located in an area outside the location of the medical department, a first help letter is sent to the medical department and copied to the family members. If the user is located at the location of the medical department, the first help message is stopped from being sent to the medical department.

[0024] Preferably, an acceleration sensor is used to obtain the user's behavior status information, and a heartbeat detection module, a blood pressure detection module and a temperature sensor are used to obtain the user's heartbeat, blood pressure and body temperature respectively.

[0025] Preferably, the acceleration sensor, heartbeat detection module, blood pressure detection module and temperature sensor are integrated on the wearable device.

[0026] Compared with the prior art, the beneficial effects of the home safety monitoring method for the elderly disclosed in the present invention are:

[0027] 1. Include falls of the elderly in the monitoring scope and participate in the judgment of dangerous events that occur to the elderly.

[0028] 2. The present invention classifies dangerous events into levels. Only when the elderly encounter a level one emergency dangerous event that may lead to serious consequences will they seek help from medical departments and take emergency measures.

[0029] 3. Make falls among the elderly included in the classification of risk levels of dangerous events.

[0030] 4. Involve the elderly’s inherent underlying diseases in the evaluation of their physical health indicators.

[0035] In order to keep the following description of the embodiments of the present invention clear and concise, detailed descriptions of well-known functions and well-known components are omitted.

[0036] The present invention discloses a method for monitoring the safety of elderly people at home. The method is run on a communication platform. The communication platform includes: a memory, a processor, and a computer program stored in the memory and run by the processor. Figure 1 and Figure 2 As shown, the method includes the following steps:

[0037] S10: Obtain the user's personal information. Specifically, the user's personal information includes the user's identity information and inherent disease information. The identity information includes: the user's age, gender, identity ID, detailed residential address, the user's contact information, the name of the family member who lives with the user or lives closest to the user, the relationship with the user, and the contact information. The inherent disease information includes the user's disease type information (such as hypertension, heart disease, diabetes), normal range information of physiological indicators strictly related to the type (such as systolic blood pressure of 110-120㎜Hg is a normal range) and range information that is outside the normal range of physiological indicators that doctors consider acceptable (for example, for users with hypertension, the systolic blood pressure value is 120-140㎜Hg, which doctors consider to be an acceptable range). The above information is stored in the memory of the communication platform.

[0038] S20: Acquire the user's physiological indicator information and behavioral status information in real time. Specifically, the physiological indicator information includes but is not limited to blood pressure indicators, heart rate indicators, and body temperature indicators, and the behavioral status information mainly includes information on whether the user has fallen. The physiological indicator information and behavioral status information can be monitored using an existing wearable device, which integrates a blood monitoring module, a heart rate monitoring module, and a temperature sensor for monitoring blood pressure indicators, heart rate indicators, and body temperature indicators, as well as an acceleration sensor for monitoring whether the user has fallen (based on monitoring whether the user has generated a large acceleration to determine whether the user has fallen).

[0039] S30: Determine whether a dangerous event has occurred based on the user's physiological indicator information and behavioral status information obtained in real time. If it is determined that a dangerous event has occurred, seek help from the outside world and record the dangerous event. If it is determined that no dangerous event has occurred, compare the user's physiological indicator information and behavioral status information obtained with preset physiological indicators and normal physiological indicators to obtain the user's health data information.

[0040] Specifically, dangerous events are divided into level one emergency dangerous events and level two emergency dangerous events according to the danger level; if it is determined that a level one emergency dangerous event has occurred, a first help message and a first additional information are sent to the medical department so that the user can obtain first aid treatment from the medical department, and the first help message is simultaneously copied to the family members. The first help message includes warning information and specific information of the level one emergency dangerous event that has occurred, and the first additional information includes the user's personal information and the contact information of the family members; if it is determined that a level two emergency dangerous event has occurred, a second help message and a second additional information are sent to the family members. The family members determine the handling plan for the level two emergency dangerous event based on the second help message and the second additional information. The second help message includes specific information of the level two emergency dangerous event that has occurred, and the second additional information includes information on the possible consequences of the level two emergency dangerous event and the contact information of the medical department in the user's living environment.

[0041] More specifically, judging whether a dangerous event has occurred based on the real-time acquired physiological indicator information and behavioral status information of the user includes:

[0042] Setting a first threshold and a second threshold representing a physiological sign, wherein the first threshold is outside a normal range of the physiological indicator, and the second threshold is outside the first threshold;

[0043] If the physiological indicator information obtained in real time exceeds the second threshold, or the physiological indicator information obtained in real time is between the first threshold and the second threshold and the user behavior status information is a fall, it is judged that a level one emergency dangerous event has occurred; if the physiological indicator information obtained in real time is within the first threshold and the user behavior status information is a fall, it is judged that a level two emergency dangerous event has occurred.

[0044] The following is an explanation of the rules and reasons for determining the level of the dangerous event in step S30:

[0045] The first threshold and the second threshold are benchmarks for characterizing the degree of danger of the user's physiological condition. Any monitored physiological indicator information of the user that is outside the first threshold is judged as a dangerous event due to the user's physiological condition.

[0046] If the user's physiological indicators monitored in real time are outside the second threshold, it means that the dangerous event has reached a level where medical staff must take emergency measures. Therefore, if the user's physiological indicators are outside the second threshold, the computer program directly determines that the user has experienced a dangerous event, and it is a level one emergency dangerous event.

[0047] If the user's physiological indicators monitored in real time are outside the first threshold but within the second threshold, and a fall event is detected, the computer program will determine that a dangerous event has occurred, and it is a level 1 emergency dangerous event. The reason for setting this judgment rule is that although the physiological indicators alone at this time are not enough to require medical personnel to take emergency measures, the change in the physiological indicators may be caused by the user's fall, and the physiological indicators may continue to deteriorate within a certain (relatively short) period of time. If emergency measures are not taken, if the physiological indicators continue to deteriorate, it is very likely to cause extremely serious adverse consequences, such as death.

[0048] If the user's physiological indicators monitored in real time are within the first threshold and the user's behavioral status information indicates a fall, the computer program will determine that a dangerous event has occurred, and the danger level is a second-level emergency dangerous event, which is lower than the first-level emergency dangerous event. The reason for setting this judgment rule is that although the user has experienced a fall, the fall does not cause a significant change in the user's physiological indicators. Therefore, the fall may not lead to serious adverse consequences for the user, such as death, myocardial infarction, or cerebral infarction.

[0049] The first threshold and the second threshold are set based on the heart rate index and the blood pressure index because, in the event of an emergency, these two indexes change more sensitively. The setting rules are roughly as follows: if the heart rate index is within a certain limit range or the blood pressure index is within a certain limit range, for example, if the heart rate is less than 20 or the blood pressure value (systolic pressure) is less than 40 mmHg, it is set as the second threshold. For example, if the heart rate is greater than 20 and less than 40 and the blood pressure value is greater than 40 mmHg, or the blood pressure value is greater than 40 mmHg and less than 70 mmHg and the heart rate is greater than 40, it is set as the second threshold.

[0050] The following explains the measures taken in step S30 for dangerous events determined to be of different levels.

[0051] If it is judged to be a level one emergency, the communication platform will send a first help message to the medical department (a medical department that can provide first aid measures) and family members at the same time, and send a first additional information to the medical department at the same time. The first help message includes a warning message and specific information about the level one emergency dangerous event that has occurred. For example, the warning message is a voice prompt that "User X's heart has stopped beating, and there is a high possibility of myocardial infarction. The situation is extremely dangerous." For example, the specific information about the level one emergency dangerous event is the physiological indicator data information before and after the event, and prompts the abnormal indicators that have appeared (which can be sent by telephone voice, such as dialing 120 and answering the call, and providing the above information by voice). The first additional information includes the user's personal information and the contact information of the family members. The first additional information can be obtained from the registration information. The personal information provided to the medical department especially includes the user's inherent disease information to help medical staff make adequate first aid preparations. The purpose of sending the first help message to family members is to inform the family members to return to the user's residence as soon as possible to cooperate with medical staff so that the user has a caregiver.

[0052] If it is determined to be a level 2 emergency, the communication platform will not send a request for help to the medical department, but will only send a second request for help and a second additional information to the user's family. The second request for help includes the specific information of the level 2 emergency dangerous event that occurred, and the second additional information includes the possible consequences of the level 2 emergency dangerous event and the contact information of the medical department in the user's living environment. For example, the specific information of the level 2 emergency dangerous event includes the physiological indicator data before and after the event, and prompts the abnormal indicators that appear. The possible consequences of the level 2 emergency dangerous event may be, for example, "the user is unable to act on his own." Based on this information, the family can choose whether to first seek help from the medical department to take first aid measures or to go to the user's room to observe the situation before making a decision.

[0053] Preferably, in this method, after determining that a dangerous event has occurred and is a Level 1 emergency, the user's location information is also obtained and, based on this information, a decision is made as to whether to send a call for help to a medical department. Specifically, if the user is located outside the medical department's location, a first call for help message is sent to the medical department and a copy is sent to the family. If the user is located within the medical department's location, the first call for help message is stopped. This step effectively prevents users from continuing to send requests for help to medical staff even after they have already received medical assistance.

[0054] Preferably, the memory not only stores the normal range data of physiological indicators, but also stores preset physiological indicators set based on the user's inherent diseases. The preset physiological indicators are located at the boundary of normal physiological indicators in terms of indicators related to fixed diseases. For example, if the user is a hypertensive patient, the preset systolic blood pressure indicator of the preset physiological indicator is 120-140 mmHg (normal systolic blood pressure is 110-120 mmHg). In this method, the monitored physiological indicator information is not only compared with the normal physiological indicators but also compared with the preset physiological indicators, thereby obtaining two data reports and evaluations. The purpose of such a setting is: for users with inherent diseases, it is difficult for their physiological indicators related to the inherent diseases to be consistent with normal physiological indicators, and the purpose of user treatment and monitoring is not to pursue consistency with normal physiological indicators, but to reach the boundary of normal physiological indicators, that is, to reach the preset physiological indicators.
