Description

  The present invention relates to an indoor accident avoidance system for avoiding attacks such as heart diseases and brain diseases indoors and a fall accident and drowning accident associated therewith.

Inadvertent death in the home is due to changes in the environment, such as temperature differences, from room to room or from area to area, and the resident's body was unable to cope with it. There are many cases caused by drowning accidents.
Various stresses on the human body exist even indoors, especially when going out of the futon, at the time of undressing before bathing, when entering the bathroom after undressing, or going out of the bathroom from the bathtub It is said that relatively strong stress is applied to the human body during, before and after excretion and during excretion.
And if a sudden temperature change, posture change, etc. are added to them, the physical condition of the elderly person, the sick person, etc. as well as the person who has a potential disease factor deteriorates.

Many attempts have been made to detect biological information such as heartbeat, respiration, blood pressure, body temperature or body movement using various sensors and detect abnormalities in the human body in certain places and areas such as toilets and bathrooms. (For example, refer to the following patent document).
However, none of them is limited to preventing the worst situation by detecting an abnormal situation, and it cannot be said that it is a method to support further physical condition in an abnormal situation. It could not be said that it was a systematic and mechanical support method to the extent of preventing and warning.

It is explanatory drawing which shows the Example of the indoor accident avoidance system by this invention.

Embodiments of an indoor accident avoidance system according to the present invention will be described below in detail with reference to the drawings.
The example shown in FIG. 2 includes various sensors, various input / output devices, a CPU, a timer (calendar), a ROM, a RAM, a recording medium such as a hard disk, and hardware resources such as an input / output interface and a communication interface. This is an example in which the indoor accident avoidance system is realized as a computer system in which programs such as an operation system OS and an application program AP are installed (see FIG. 2A).

  In this example, a human body information detection sensor 1 that is installed indoors and detects biological information such as heartbeat, breathing, blood pressure, or body movement (movement of the head, torso, and limbs) and the biological information or changes thereof. A biodiagnosis unit 2 that estimates the detected state of the living body, a undulation determination unit 3 that guides the undulation change of the body posture including standing, sitting or supine from the change in body movement or the movement of the living body; and the undulation determination unit 3 Is provided with an intervention means 4 for alerting a warning, advice, advice, etc. or notifying biometric information in accordance with the estimation result of the biodiagnostic means 2 when it is determined that the posture changes or the movement of the living body (FIG. 2 ( B)).

  The human body information detection sensor 1 includes a microwave sensor such as a microwave Doppler sensor (see, for example, JP-A-2002-71825), an image sensor such as a CCD, or an infrared sensor (see, for example, JP-A-2002-279428) or the like. Or a combination.

The microwave sensor detects a microwave received by the detection unit, and derives a motion point vector (direction and amount of motion) and position coordinates from the detected component, and from them, heartbeat, respiration and blood pressure are derived. In addition, the body position and movement vector of the living body are derived (see Patent Document 2). When these are derived numerically, either a relative value or an absolute value may be used.
The image sensor detects the appearance and movement of a living body with an image.
In order to protect the privacy of a living body, it is desirable that the resolution is low enough that details of the living body cannot be recognized. For example, the body position and movement of the living body can be derived by calculating the center of gravity of the photographed moving body (see Patent Document 1).
The infrared sensor detects the presence / absence of a living body, the shape of the living body, and the temperature distribution of the living body and its surroundings, and derives the body position and movement of the living body from the shape of the living body in the same manner as the image sensor. From the distribution, changes in the temperature of the environment to which the living body is exposed and the body surface temperature can be derived.

The biodiagnosis unit 2 stores the biometric information in a recording unit in association with the date and time output by the timer.
The biodiagnosis unit 2 includes, for example, a group of comparators that guide various aspects related to a living body, and each comparator evaluates an output of the human body information detection sensor 1 with respect to each of the biometric information or a change threshold thereof, and the threshold value Based on the deviation value with respect to, the estimation result relating to the state of the living body is output.
In addition, the biodiagnosis means 2 includes the timing of heartbeat, respiration or blood pressure change (warning flag B) guided by the human body information detection sensor 1, and the undulation change and defense of the body position guided by the human body information detection sensor 1. A temporal relationship with a change in the region, a change in the air temperature, and a change in the temperature distribution of the living body (warning flag A) is evaluated based on the output of the timer included in the system.

The undulation determining means 3 is collated with a table having general information for deriving a standing, middle waist, sitting, middle waist or supine position from the combination of the body motion vector and the body motion vector, It is determined whether or not the posture changes between postures, and the body movement that exceeds the posture changes is determined to be movement.
Detecting a change from a lateral or prone position to a sitting position, a change from a sitting position to a middle waist, or a change from a middle waist position to an upright position, in order to intervene before a large body position change is performed, It is desirable to have a configuration that suppresses subsequent actions before reaching an important point. In particular, it is desirable that the transition from the lateral position to the prone position is detected as accurately as possible because there is a high possibility that the body position changes from the middle waist position to the standing position.

The intervention means 4 refers to the output of the biodiagnostic means 2 when the undulation determination means 3 determines that the category of the same posture has been exceeded, and in accordance with the estimation result derived by the comparator For example, “There is a possibility that the life may be dangerous”, “Do not move now”, “Return to the original posture (or place)”, “Wake up slowly over time. "Or" blood pressure (heart rate) is 150 (or tachycardia or bradycardia). "
Further, the intervention means 4 holds a recording table for setting and holding a temperature environment (such as temperature) and a living environment (such as a step or an obstacle) for the defensive area of each human body information detection sensor 1, and notification matters It is a reference requirement when determining

In this example, the movement of the living body (the warning flag A) is guided by the undulation determination means 3 from the change in body movement guided by the human body information detection sensor 1, and the intervention means 4 refers to the recording table. If there is an obstacle area such as a step in the defensive area of the human body information detection sensor 1 or there is a possibility that the movement of the living body may extend to multiple defensive areas that sandwich the obstruction area, there is a “step (an obstacle area). "Please be careful."
In particular, when it is estimated that the state of the living body guided by the living body diagnostic means 2 when the movement of the living body is detected is accompanied by wobbling or stride variation (the warning flag B), “Sit down and wait for a while.” To prevent accidents such as falling or falling by outputting voice alerts or images.

In this example, the undulation change of the posture including the standing position, the sitting position, the middle waist position or the prone position is derived from the determination by the undulation determination means 3, and the time of the undulation change of the body position and the time of the change of the biological information are collated. The diagnostic means 2 and the biodiagnostic means 2 include the intervention means 4 that prompts maintenance of the body position before the change when it is determined that the timing of the change coincides.
The collation in the biodiagnosis means 2 is determined to coincide with each other when, for example, a change occurs in the biometric information within a certain period of time, based on, for example, the time when the body posture changes.

This example employs a configuration that promptly detects a deterioration in physical condition (such as a sudden change in vital signs) associated with a change in body posture, and works to shift to or return to a position that reduces the deterioration of the physical condition as much as possible. It is.
This is because, for example, when the blood suddenly rises from the supine position to the standing position, the blood moves to the torso due to the action of gravity, and as a result, blood is difficult to flow into the brain for a short time. This is an example that can prevent dazzling due to sudden changes, consciousness or fainting, or a fall accident associated therewith.
In particular, elderly people and living bodies undergoing hypertension treatment stand in the toilet at night (see Fig. 3), stand after urination (see Fig. 4), or stand up from a warm bathtub in a bathroom with relatively low temperature. (See Fig. 5), it is said that such an accident is likely to occur.

The biodiagnosis means 2 constantly evaluates changes in heartbeat, respiration, blood pressure, or body movement of biometric information (see FIG. 1 (B)), and the heartbeat, When the breathing or blood pressure reaches a warning level, the intervention means 4 is notified (see FIG. 1C).
In such a case, the intervention means 4 outputs a warning such as “Please sit down” or “Lower your head” by voice or image.

  In this example, the human body information detection sensor 1 installed in a defensive area having a plurality of areas having different temperature environments, and the biodiagnosis means for collating the undulation change of the body position or the time of movement of the living body and the time of change of the biometric information 2 and the biomedical diagnosis means 2 include the intervention means 4 that prompts the maintenance of the temperature environment before the change when it is determined that the time of the change coincides.

The collation in the biodiagnosis means 2 is determined to coincide with each other when, for example, a change occurs in the biometric information within a certain period of time, based on, for example, the time when the body posture changes.
In this example, as a defensive area where the living body belongs to an area having a different temperature environment due to the undulation change of the body position, a bathroom (see FIG. 5) having a warm tub and a relatively cold outside the tub, or a warm futon Or, it is an example configured as an indoor accident avoidance system that functions when the undulation change of the body position is directly connected to the change of the temperature environment, assuming the inside of the kotatsu and the room where the temperature is relatively low (see FIG. 3).

In this example, the undulation determining means 3 guides the undulation change of the body position and the movement of the living body (the warning flag A) from the change of body movement guided by the human body information detection sensor 1, and the body position changes undulating or In addition to the movement, the structure that promptly senses the deterioration of the physical condition accompanying the change of the temperature environment at the same time, and works to move to or return to the position or the position that alleviates the deterioration of the physical condition as much as possible. .
This is because, in addition to the change in physical condition described in Example 2 above, if a difference in temperature environment occurs in a short time, blood pressure rapidly rises and falls, causing a heavy burden on the heart and blood vessels, and triggering myocardial diseases and the like. It is the structure which prevents becoming in the same room (area | region).

At this time, the biodiagnosis unit 2 detects changes in heartbeat, respiration, and blood pressure in the biometric information at an early stage, and notifies the intervention unit 4 when the alert level is reached (see FIG. 1B).
In such a case, the intervention means 4 decides the notification contents by taking into account the fact that there is a temperature gap in the defense area of the human body information detection sensor 1 in the judgment requirement in light of the recording table, "Please take a shower.", "Take a shower before entering the bathtub.", "Please put something on before you get up." Or "The room seems cold." Output as an image.

  In this example, the human body information detection sensor 1 installed in a defense area having a plurality of areas having different temperature environments, a living body existing in the defense area of the human body information detection sensor 1, and a temperature distribution for detecting temperature distribution around the living body information detection sensor 1 When the sensor, the biodiagnosis unit 2 for collating the change timing of the temperature distribution and the change timing of the biometric information, and the biodiagnosis unit 2 determine that the timing of the change coincides, The intervention means 4 for promoting maintenance of the placed temperature environment is provided.

In this example, the undulation determining means 3 guides the undulation change of the body position and the movement of the living body (the warning flag A) from the change of the body movement guided by the human body information detection sensor 1, and the body position is undulated and changed. Move, detect early deterioration of physical condition due to the difference between the temperature distribution of the living body and the temperature distribution of the region surrounding the living body, and work to shift to or return to a posture that can alleviate the deterioration of the physical condition as much as possible The configuration is adopted.
Similarly to the third embodiment, when the difference in temperature environment occurs in a short time, the blood pressure rapidly rises and falls, causing a heavy burden on the heart and blood vessels and triggering myocardial disease and the like. This is a configuration to prevent in the room (region).

At this time, the biodiagnosis unit 2 detects changes in heartbeat, respiration, and blood pressure in the biometric information at an early stage, and notifies the intervention unit 4 when the alert level is reached (see FIG. 1B).
In such a case, the intervention means 4 said, “The hot water is too hot. Let the temperature of the hot water be 40 degrees or less.”, “Put your chest out of the bathtub.”, “Take a shower before getting up. "Please take a shower before entering the bathtub.", "Please put something on." Or "The room seems to be cold."

In these embodiments, the biodiagnosis unit 2 determines that the timing of the change is when the biometric information reaches a warning area before the temperature distribution accompanying the change in body posture or the movement of the living body occurs. It is not necessary to determine whether or not they match, and the determination (warning flag B) of the biodiagnosis means 2 is notified to the intervention means 4 when the undulation change by the undulation determination means 3 or the movement of the living body is triggered. (See FIGS. 1A and 1C).
Further, when the biometric information reaches a dangerous area before the undulation change or the movement of the living body occurs, a notification is made to a predetermined contact without waiting for the undulation change by the undulation determining means 3. It is also possible to provide a reporting means (see FIG. 1B).

  In this example, the human body information detection sensor 1 installed in a plurality of defensive areas that have connectivity in the detection period of body movement and have different temperature environments is collated with the time of change of the defensive area and the time of change of biological information. When the biodiagnosis unit 2 and the biodiagnosis unit 2 determine that the timing of the change coincides, the biodiagnosis unit 2 includes the intervention unit 4 that promotes maintenance of the temperature environment before the change.

The collation in the biodiagnosis means 2 is determined to coincide with each other when, for example, a change occurs in the biometric information within a certain period of time with reference to the time when the defensive area changes.
Here, a plurality of defensive areas that have connectivity in the detection period of body movement and have different temperature environments are a series of movement ranges (flow lines) that connect between the stay period and the stay period, especially in body movements that involve movement. A plurality of defensive areas including at least one definite difference in temperature (hereinafter referred to as “temperature disparity”) between the defensive areas. If the temperature difference exists between the plurality of defense areas, it does not matter whether the plurality of defense areas are adjacent or continuous.

  In this example, as a plurality of defensive areas having connectivity and different temperature environments in the detection period of body movement, between a warm living room or bedroom and a cold toilet or hallway (see FIG. 6), and a cold dressing room and bathroom Or it is the example of a structure of the indoor accident avoidance system which functions when a living body is exposed to the rapid change of a temperature environment, assuming between hot water of the bathtub, etc. (refer FIG. 7).

In this example, the movement of the living body (the warning flag A) is guided by the undulation determination means 3 from the change in body movement guided by the human body information detection sensor 1, and the temperature environment changes simultaneously with the movement of the living body. A structure is adopted in which deterioration of physical condition is detected at an early stage and measures are taken to take measures to alleviate the deterioration of physical condition as much as possible.
This is the same as in the third embodiment, when the difference in temperature environment occurs in a short time, the blood pressure rapidly rises and falls, temporarily causing a heavy burden on the heart and blood vessels and triggering myocardial disease and the like. This is a configuration to prevent when moving between different indoor rooms.

At this time, the biodiagnosis unit 2 detects changes in heartbeat, respiration, and blood pressure in the biometric information at an early stage, and notifies the intervention unit 4 when the alert level is reached (see FIG. 1B).
In such a case, the intervention means 4 decides the notification contents by taking into account the fact that there is a temperature difference in the defense area of the human body information detection sensor 1 in the judgment requirements in light of the recording table. Please put on your clothes. "" The room seems to be cold. "" The blood pressure seems to be high. "" I think it is safer not to bathe today "or" Please call people without moving. " Etc. are output by voice or image.

  This example is also an example provided with the human body information detection sensor 1 installed in a plurality of defense areas having connectivity in the detection period of body movement, but each of the defense area of each human body information detection sensor 1 A temperature sensor for detecting the temperature, the biodiagnosis means 2 for collating the timing of the change of the biological information detected by the human body information detection sensor 1 with the timing of the movement of the defensive area accompanying the change of the temperature, and the biodiagnosis means 2 includes the intervention means 4 for urging the maintenance of the temperature environment before the change when it is determined that the timing of the change of the biological information coincides with the timing of the movement of the defensive area accompanying the change of the temperature.

In this example, the temperature of each defensive area is detected so that it can be adapted to changes in various indoor temperature environments, such as opening windows for ventilation in summer and winter, and stopping air conditioning equipment. This is an example of detecting a relationship between a temperature difference and biological information of a living body that crosses an environment where the temperature difference exists.
The collation in the biodiagnosis unit 2 determines that the timings coincide with each other when a change occurs in the biometric information within a certain time on the basis of the change in the defensive area where the temperature difference exists.

  In this example, similar to the fourth embodiment, the movement of the living body (the warning flag A) is guided by the undulation determining means 3 from the change in body movement guided by the human body information detection sensor 1, and simultaneously with the movement of the living body. A structure that promptly detects deterioration of physical condition due to changes in temperature environment and works to reduce the deterioration of physical condition as much as possible, but has connectivity in the detection period of body movement. The indoor accident avoidance system having a configuration that can adapt to various flow lines where the temperature difference actually occurs unexpectedly without being limited to the assumption described in the fourth embodiment as a plurality of defensive areas with different temperature environments. It is a structural example.

In this example, the biodiagnosis unit 2 detects changes in heart rate, respiration, and blood pressure in the biometric information at an early stage, and notifies the intervention unit 4 when the alert level is reached (see FIG. 1B).
In such a case, the intervention means 4 “please return to a warm room quietly”, “warm your body”, “please put on something”, “the room seems cold”. , "Please close the window.", "Please call a person without moving as it is" or "Please sound an alarm."

  In this example, the human body information detection sensor 1 installed in a plurality of defense areas having connectivity in the detection period of body movement, the temperature distribution sensor for detecting the temperature distribution of the defense area of each human body information detection sensor 1, The biodiagnosis means 2 for collating the timing of the change of the biometric information detected by the human body information detection sensor 1 with the timing of the movement of the defensive area accompanied by the change in the temperature distribution of the living body, and the biodiagnosis means 2 The intervention means 4 for urging the maintenance of the temperature environment before the change when it is determined that the times coincide is provided.

This example detects the temperature distribution of each defensive area so that it can adapt to various changes in the temperature environment surrounding the living body indoors, and changes in the temperature distribution of the living body and the area surrounding the living body, It is an example which detects the relationship with the change of the biological information of the biological body which crosses the environment where a temperature gap exists.
The collation in the biodiagnosis unit 2 determines that the timings coincide with each other when a change occurs in the biometric information within a certain period of time with reference to a time when the temperature distribution changes more than a specified value.

  In this example, as in the third embodiment, the movement of the living body (the warning flag A) is guided by the undulation determination means 3 from the change in body movement guided by the human body information detection sensor 1 and simultaneously with the movement of the living body. The body itself or the structure surrounding the living body and the surrounding area is used to detect the deterioration of the physical condition accompanying the change in temperature and to take measures to reduce the deterioration of the physical condition as much as possible. As a plurality of defensive areas having connectivity in the motion detection period and different temperature environments, the structure is not limited to the assumption described in the third embodiment, and has a configuration that can be adapted to various flow lines in which the temperature distribution actually changes. It is a structural example of an indoor accident avoidance system.

In this example, the biodiagnosis unit 2 detects changes in heart rate, respiration, and blood pressure in the biometric information at an early stage, and notifies the intervention unit 4 when the alert level is reached (see FIG. 1B).
In such a case, the intervention means 4 is “please return to a warm room quietly”, “warm up your body”, “please put on something”, or “your body seems to have cooled down. "Please call a person without moving as it is" or "Please sound an alarm."

  In these embodiments, the biodiagnosis means 2 is configured so that the biometric information reaches the alert area before the human body information detection sensor 1 in charge of the defensive area for detecting the living body changes between the defensive areas with a temperature difference. When the human body information detecting sensor 1 is in charge of the defensive area for detecting the living body, the human body information detecting sensor 1 is switched between the defensive areas with a temperature difference. Then, the determination (warning flag B) of the biodiagnosis means 2 is notified to the intervention means 4 (see FIGS. 1A and 1C).

  Furthermore, when the human body information detection sensor 1 in charge of the defensive area for detecting the living body changes between defensive areas with a temperature difference, the defensive area for detecting the living body is detected when the biometric information reaches the danger area. Without waiting for the human body information detection sensor 1 in charge to change between defensive areas with a temperature difference, it is also possible to provide a reporting means for notifying a predetermined contact (see FIG. 2B).

  In the embodiment described above, the alerting or the notification of biological information performed by the intervention means 4 is not only for the person to be watched, but also “Please call out”, “It seems that the bathing time is longer than usual. , Etc., can be prevented by encouraging the family member to confirm or alerting them with an output through a speaker, a TV screen, or mail transmission to a mobile terminal. For example, on the television screen, the contact information, the report destination, the procedure of the measure, the medicine, the contents of assistance, the method, and the like can be displayed only for a necessary time.

Further, based on the warning flag A (such as body posture) or the warning flag B, it is possible to take drought countermeasures such as forced drainage of bathtubs, heat retention countermeasures such as thermal insulation control, or dehydration countermeasures such as sauna stop.
Furthermore, by recording the biometric information notification contents and vital signs that are constantly measured as life diaries in chronological order, it is used for living environment and physical condition management / improvement. It can also be used as linkage data.
