Description

The present invention relates to a vital information generation device that artificially generates body movements of a living body (various organisms including mammals, reptiles, birds, etc.), pulsations and pulsations generated in the living body, and various noises.

Today, as in Patent Documents 1 to 4 below, many systems that detect vital information using the Doppler effect, verify the condition of the subject in various ways, and respond appropriately to the verification results have been introduced. (For example, see Patent Document 1 below).

Regardless of the method used to collect vital information, it is essential to secure a large number of diverse samples in order to obtain accurate verification results, while ensuring the functionality and accuracy of individual systems. It is also indispensable to confirm the operation of outputting more probable verification results for various vital information and its combinations and combinations of them with noise before shipping.

However, there is a big problem that it is extremely difficult to ask living organisms to be samples for confirming the operation of individual systems.
In addition, since there is a certain limit to the vital information that can be obtained as long as a living organism is used as a sample, it is difficult to quantitatively verify the diagnostic criteria.
Even with these backgrounds, it is inevitable to confirm the stable operation of each system that is actually operated and to provide a certain guarantee sufficient for practical use in life-threatening applications.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vital information generator capable of quantitatively supplying various vital information, combinations thereof, and combinations thereof and noise.

The vital information generator according to the present invention, which has been made to solve the above problems, has a motion region that causes a beat, an actuator that imparts the amplitude and vibration rhythm of the beat to the motion region, and the actuator that has the amplitude and vibration. It is characterized by including a generator that supplies driving energy that excites a rhythm, and a control unit that supplies a control signal for generating the driving energy to the generator.

The pulsating portion is provided with a single or a plurality of pulsating portions that perform pulsations that serve as vital information, and a damper portion that supports the pulsating portions and allows the pulsating amplitude of ecological organs. A configuration may be adopted including an actuator that gives the amplitude and vibration rhythm of the pulsation. The damper portion is required to have a configuration or a property that allows a stroke given by the actuator.
Specifically, there is a configuration in which the pulsating portion and the damper portion are integrally configured, and the elasticity of the pulsating portion and the damper portion is different in the damper portion.

The motion region may be configured to include a multi-layered motion region in which one motion region includes another motion region (see, for example, FIG. 5).
That is, by providing a single or a plurality of motion regions separately provided with an actuator inside the outer edge of the large motion region, a partial difference in motion is given to the motion region.

When giving a three-dimensional movement to one pulsating part, it is possible to adopt a configuration in which a plurality of actuators are connected to one pulsating part.

According to the vital information generator according to the present invention, it is possible to perform stable operation confirmation for each system actually operated and to provide a certain guarantee sufficient for practical use in a life-threatening application, and various vitals can be provided. It contributes to the provision of a vital information generator capable of quantitatively supplying information, a combination thereof, and a combination thereof and noise.

As a result, there is no need to use living organisms as samples, such as requesting living humans as samples to confirm the operation of individual vital information collection systems, based on information collected from various clinical cases. It is possible to realize vital information of various cases and quantitatively verify diagnostic criteria using a pulsation detection sensor such as a Doppler sensor that detects microwaves.

It is a block diagram (including the front view of the motion area) which shows an example of the vital information generation apparatus by this invention.

Hereinafter, embodiments of the vital information generation device according to the present invention will be described in detail with reference to the drawings.
The vital information generator shown in the figure is an example of one used for confirming the operation of a human vital information detection system using a Doppler sensor.

The Doppler sensor is a sensor that utilizes the Doppler effect of microwaves.
This sensor is a sensor that can detect not only the movement and body movement of a person but also the respiration and heartbeat from the movement of internal organs as long as microwaves can pass through.
The sensor is placed so that the entire life of the resident can be seen, such as the toilet, washroom, kitchen, bath, corridor, stairs, and entrance of the house, and the installation mode is camouflaged inconspicuously or embedded in the wall or ceiling. (For example, see Japanese Patent Application Laid-Open No. 2002-117466).

The example shown in FIG. 1 is an exercise that produces a pulsation in order to quantitatively reproduce the movement of a human internal organ such as a heartbeat, a pulse, or a breath with a plurality of parameters and combinations thereof at a sufficient level for operation confirmation. The region 1, the actuator 2 that imparts the pulsatile amplitude and vibration rhythm to the motion region 1, the generator 3 that supplies the driving energy that excites the amplitude and vibration rhythm to the actuator 2, and the drive to the generator 3. A configuration including a control unit 4 for supplying a control signal for generating energy is adopted.

The motion region 1 of this example is elastic by spraying metal (such as aluminum) particles that do not transmit the microwaves generated by the Doppler sensor (eg, have a reflectance of 50% or more for microwaves ranging from 10 GHz to 24 GHz). It is made of a material, an elastic material on which a metal thin film is formed, etc., and supports a single or a plurality of pulsating portions 1a that perform pulsations that serve as vital information, and allows the pulsating amplitude of an ecological organ. A damper portion 1b is provided.
In this example, the pulsating portion 1a and the damper portion 1b are integrally configured, and the damper portion is more than the pulsating portion 1a due to a difference in wall thickness or material, or a morphological difference such as a bellows shape or a flat shape. A treatment is applied to increase the elasticity of 1b.
The motion region 1 may take a form of beating while maintaining a dome shape.

The actuator 2 in this example is due to electromagnetic induction, and is elastically supported by the fixed portion A fixed to the frame C and the fixed portion A to move forward and backward on a constant orbit with respect to the fixed portion A. It is composed of a movable portion B.
A movable portion B and a fixed portion A whose ends are in the amplitude direction of the moving region 1 are arranged vertically, and a constant magnetic field is applied to either the movable portion B or the fixed portion A on the back side of the moving region 1. By forming an electromagnet and using the other as an electromagnet or a permanent magnet that forms a constant magnetic field by directing the magnetic pole to the one (see, for example, FIG. 1), the exciting coil of the electromagnet has a drive current synchronized with the beating signal. When (the driving energy) is passed, a beat following the amplitude and vibration rhythm of each waveform of the beat signal is generated in the motion region 1.

The control unit 4 collects vital information such as pulse, heartbeat, and breath as reference data (for example, amplitude pattern) based on the output information of the Doppler sensor for various vital information obtained from a limited sample. The data table 5, the environmental data table 6 collected as reference data for noise generated in the living environment (such as shaking of the human body during walking and shaking when the vehicle is running), and one or more reference data included in the control unit 4. A mixer 7 is provided which outputs a control signal by combining the above with desired outputs.

The reference data of each vital information can be used by superimposing them on each other as noise according to the inspection content.
It is also possible to provide an event data table 8 collected as reference data for event information such as body movement, cough, meal and fall, which is composed of a combination of the vital information and environmental information.
The reference data in each of the tables 5, 6 and 8 can be stored from an input means 9 such as various communication ports, various storage media ports or a keyboard.

The generator 3 receives a control signal output by the control unit 4 and supplies a drive current that produces a desired amplitude to the exciting coil of the actuator 2.
It is desirable to give fluctuations to the control signal with respect to its amplitude, period, and the like.
Fluctuation is a biological reaction that occurs in response to stress or fatigue because the living body flexibly adapts to changes from the outside world.
Since the under-or over-or modulation of the fluctuations objectively or quantitatively indicates not only fatigue and stress but also dysfunction and temperamental lesions, the control unit 4 may give the fluctuations to the control signal. It is desirable to adopt a configuration including a fluctuation generating means.

Examples of the fluctuation include fluctuations in the local acceleration pulse wave waveform, fluctuations in the Peak-Peak interval, and the like.
The fluctuation of the local acceleration pulse wave waveform is a fluctuation reflecting the flexibility of the blood vessel, and is positioned as a precursor index of arteriosclerosis.
The fluctuation of the Peak-Peak interval is a fluctuation that reflects heart rate variability and is positioned as an index for evaluating the balance of autonomic nerves such as stress and fatigue.
The amplitude and vibration rhythm that realize these beats are generated by the control signals combined by the mixer 7.

For example, as shown in FIG. 1, the vital information generator composed of a single motion region 1 and a single actuator 2 can be driven by a drive current of 0.5 Hz to 2.0 Hz with a predetermined amplitude. , A pulsation that reaches the pulse can be obtained, and if a plurality of actuators 2 are provided in a relatively large motion region 1 and a drive current of 2 Hz to 20 Hz is applied with a predetermined amplitude, the pulsation that reaches the body movement can be obtained. Can be obtained.
Further, if a driving current of 0.1 Hz to 3 Hz is applied to the motion region 1 or the pulsating portion 1a thereof with a predetermined amplitude, a pulsation that reaches the brain wave can be obtained.

For example, as shown in FIG. 2, a plurality of motion regions 1 and a plurality of frames C supporting the actuator 2 may be three-dimensionally arranged on the base frame to integrally form a three-dimensional vital information generation device.
The general appearance of the heart in normal sinus rhythm is that the left and right ventricles expand relatively slowly, triggered by the relatively rapid contraction of the left and right ventricles, and the left and right atrium contracts in synchronization with the expansion of the left and right ventricles. (See FIGS. 2 and 3 (A)).
On the other hand, for example, in ventricular tachycardia, the expansion and contraction of the left and right ventricles and the synchronization with the left and right atrium are lost, and the expansion and contraction frequency of the left and right ventricles increases randomly at 120 to 250 / min (see FIG. 3 (B)). ).
This vital information generator gives each actuator 2 a pulsation that leads to the movement of the heart by giving a drive signal for each part subordinate to the movement of the heart to each actuator 2. It can be given to each part.

In addition to the example of the heart, the vital information generator that reproduces the above symptoms may perform one or more of the above-mentioned movements of the chest and abdomen during breathing according to the direction of microwave irradiation from the Doppler sensor. It can be assembled in a single or a plurality of motion regions 1 assembled by the pulsating portion 1a and the damper portion 1b.
