Description

[0001]
[Industrial application fields]
The present invention relates to a blood circulation promoting device that detects a biological signal, applies a stimulus to the living body within a range based on the detected biological signal, and promotes blood circulation.
[0002]
[Prior art]
Although many devices that provide electrical stimulation, mechanical stimulation, etc. to the body to promote blood circulation are provided, most of them merely provide stimulation, and the stimulation is reflected in blood circulation promotion. It is not clear whether or not.
[0003]
[Means for Solving the Problems]
In view of the above, the present invention is possible by proposing a blood circulation promoting device including a stimulation unit that outputs electrical stimulation and physical stimulation and outputs stimulations having different properties within a range based on detected biological signal information. By trying to promote blood circulation as much as possible and adding two different stimuli, a comfortable stimulation sensation that could not be achieved in the past has been realized, and the present invention has been achieved. The biological signal information shown in the present invention indicates one or a combination thereof such as an electrocardiogram, a heart sound diagram, a pulse wave, and a heartbeat. However, the biological signal information is not limited to this and is detected by a means that can be detected as biological information. If it is, it will not specifically limit. Although the application site | part of this invention is suitably selected according to the use mentioned above, More specifically, application to site | parts, such as an abdominal part and a leg part, or the whole body is illustrated .

The pressurized air in the reservoir 7 is supplied to the pressurizing elastic bags 17 and 18 through the pressurizing valve 8 and the conduit 12, and the pressurizing elastic bags are inflated.
At the same time, the electrical stimulation pulse output from the electrical stimulation pulse generating means 4 is applied to the electrodes 15 and 16 via the electrical leads 13 and 14.
FIG. 2D shows the transition of pressurization with respect to the pressurizing elastic bags 17 and 18. The expansion of the pressurizing expansion and contraction bags 17 and 18 pressurizes the living body part to which these are attached, and an electrical stimulus is applied as shown in FIG.
When the next pulse wave arrives, the input unit 2 outputs a systolic pulse, and the control unit 3 inputs the signal to output an electrical stimulation pulse and stop the pressurization. And output to the pressure adjusting means 5.
The electrical stimulation output unit 4 stops the operation in response to this signal, and the pressurization adjusting means 5 outputs a signal for closing the pressurization valve 8 and a signal for opening the decompression valve 9.
When the pressurizing valve 8 is closed and the decompression valve 9 is opened, air inside the pressurizing expansion and contraction bags 17 and 18 comes out, and the pressurization of the living body is stopped.
Although the above operation is performed for each pulse wave, pressurization and electrical stimulation may be applied every one to several pulse waves.
The frequency of the electrical stimulation is several Hz to several hundred Hz and the amplitude voltage is up to about 300 V, but is not limited to the pulse, and may be other electrical stimulation modes such as alternating wave electrical stimulation. In addition, in the form of electrical stimulation, a pair of electrodes is further added, a high frequency of several KHz to several tens of KHz is given to each pair of electrodes, and the frequency difference is low at a portion where these two high frequency currents intersect in the body. Interference wave electrical stimulation that generates frequency stimulation may be used. For this interference wave electrical stimulation, techniques described in JP-A-2-140135, JP-A-58-206760 and the like are preferably used.
The extent of pressurization, varies depending on the site, at least Ri higher pressure der than venous pressure at the site 40mmHg~60mmHg is shown.
In addition to the above, an electrocardiogram, a heart sound diagram, and a combination thereof can be used as the biological signal detection means.
The usage time for this example is exemplified as a preferred example of 30 minutes or less once a day, but is not limited thereto.
In this way, by applying a pressing operation such as a positive pressure and applying an electrical stimulus in the diastole range and repeating this, a very pleasant stimulation and a possible blood circulation promoting operation can be achieved .

Specifically, a planar fastener and a plurality of snap fasteners are exemplified. In addition, it may be a cylindrical shape formed of a material such as rubber, vinyl, mesh cloth, or a combination thereof whose size is adjusted in advance.
