Description

Description: TECHNICAL FIELD The present invention relates to a blood circulation promoting device.

[Conventional technology]

In order to recover stiff shoulders and muscle pain, it is effective to apply electromagnetic waves to a specific part of the body to promote blood circulation.

Therefore, a blood circulation promoting device for that purpose was developed. This blood circulation promoting device is used by directly affixing it to a site where blood circulation stays, such as dust. As such a device, a single unit is configured by incorporating an electromagnetic circuit and an oscillation circuit that generates high-frequency pulses and an antenna that forms an electromagnetic field by the function of the circuit in a case recently mounted on an affected part. Has been proposed. Since this device is unitized, there are advantages such as very convenient handling.

[Problems to be solved by the invention]

By the way, the blood circulation promoting device is generally provided with a manually operated switch, and the power is generally turned on and off by the switch. If the user forgets to insert the switch, there may be a case where the electromagnetic field is not actually generated, or if the user forgets to turn off the switch, the battery power may be wasted.

Therefore, the recent blood circulation promotion device has changed from a manual switch type to
The so-called automatic switch type is adopted, in which the oscillating operation is always performed during wearing on the body and the oscillating operation is stopped by removing the body. In any of the above methods, when used, the oscillation operation was continuously performed,
This type of device, which consumes a considerable amount of current and has a limited battery capacity due to a demand for miniaturization, loses battery power early and is not suitable for long-term use.

In view of the above circumstances, it is an object of the present invention to enable a significant long-term use.

[Means for solving the problem]

In order to solve the above problems, the present invention provides an oscillation circuit comprising:
When the device is used, it is controlled so that after oscillating for a certain period, oscillation is stopped for a period during which the irradiation effect by the oscillation can be maintained, and oscillation is repeated again.

[Action]

When the oscillation circuit is used, the device oscillates for a certain period of time, then stops oscillation for a period during which the irradiation effect of the oscillation can be maintained, and repeats oscillation so that continuous irradiation of the electromagnetic field is ensured. However, the current is not changed by the amount corresponding to the stop section.

〔Example〕

Hereinafter, the present invention will be described in detail with reference to the drawings showing the embodiments.

1 to 7 show an embodiment of the blood circulation promoting device according to the present invention. This blood circulation promoting device A
Is charged when it is stored in a charger (not shown) as it is, and is detached from the charger and attached to a body or an application site such as clothing to promote the body structure. When removed from the charger, the current breaks down due to the generation of an electromagnetic field, but when stored in the charger, the battery is charged exclusively and there is no wasteful power consumption. The device A includes a disk-shaped unit case 1. The unit case 1 includes a base plate 2 located on the side to be attached to the body, and a case cover (upper part) 3 located outside the base plate 2. The base plate 2
Is a donut-shaped disk with an opening 4 in the center,
A radial ventilation groove 5 is formed on the bottom surface, and an engagement groove 6 having a projection 6a on the inner side is formed on the outer peripheral edge thereof. The case cover 3 is hermetically joined with an engaging portion 7 on the periphery of the opening fitted into the engaging groove 6. Recess 8 of base plate 2
Is provided with a printed circuit board 10 located at the opening end of the case cover 3. The board 10 has a spiral antenna (electromagnetic field generating means) on its body-mounted side.
44 (see Fig. 4) and on the opposite side,
As shown in FIG. 4, the IC circuit patterns and the IC circuit components 13 constituting the power supply circuit 40, the oscillation circuit 41, the modulation circuit 42, etc.
And LED 14 are provided. Inside the IC circuit pattern, a rechargeable battery 18 for driving the oscillation circuit 41 is provided, and connection fittings 15, 1 electrically connected to the rechargeable battery 18.
6 are also deployed. The LED 14 is used to externally determine that the therapeutic device unit A is generating a high-frequency electromagnetic field by blinking. This blinking is confirmed through the operation confirmation window 17 of the case cover 3. It has become. On the other hand, two charging terminals 20 and 21 are arranged on the surface of the printed circuit board 10 on the side of attachment to an adherend, such as the body, so as to be located at the center and the outer periphery thereof. Antennas are arranged and each is electrically connected to the IC circuit pattern via a through-hole. Since these terminals 20 and 21 are exposed, there is no need to perform a connection operation during charging. A protective sheet 25 is adhered to the bottom surface of the printed circuit board 10, and the protective sheet 25 is
Is provided with two through holes 26 and 27 so as to correspond to the terminals 20 and 21 respectively. On the body mounting surface side of the unit case 1, a thin ring-shaped mounting member 31 having a vent 32 at the center thereof is detachably attached and exchanged. The member 31 has adhesives 35, 35 on both sides.
, One of which is attached to the protective sheet 25 and the other is attached to an adhered site such as a skin surface.

Incidentally, it has been reported that irradiating a living body with an electromagnetic field by the blood circulation promoting device or the like has an effect of promoting blood circulation and the like. When the electromagnetic field acts on an affected part, vascular smooth muscle of arterioles relaxes. However, it has been found that this expands blood vessels and promotes blood circulation. As a mechanism, it has been established that Ca ²⁺ is involved in the suppression of vasoconstriction.According to this, blood vessels are contracted in a perfusate containing vasoconstrictor, It is said that the irradiation of the field causes Ca ²⁺ in the cell membrane to be pumped out of the membrane, resulting in a relaxed (shrinkage-suppressed) state.

FIG. 2 is a graph showing a change in the blood vessel diameter in an experiment on an animal having an arteriole vasculature as a condition of the presence or absence of electromagnetic field irradiation. In the graph, the horizontal axis represents the elapsed time, and the vertical axis represents the rate of change of the blood vessel diameter. The rate of change of the blood vessel diameter indicates that 0% is in a non-contracting state. If a blood vessel is placed in a perfusate containing a vasoconstrictor before 0 minutes, it becomes about -50% contracted. I have. This state is maintained unless the electromagnetic field is irradiated as shown by the broken line. However, when the electromagnetic field (EMF) is irradiated at 0 minutes as shown by the solid line, the blood vessels begin to expand, expand to about -10% after about 60 to 70 minutes, and -50% with a certain delay after irradiation. It has been found that it shrinks to. According to the above, even if the irradiation of the electromagnetic field is stopped in the middle, the extended state continues from 90 to 100. Therefore, within the range in which the extended state is continued (about 100 minutes). If the electromagnetic field is applied again in ()), it can be seen that the dilated state of the blood vessel can be continued as shown in FIG.

FIG. 4 schematically shows an embodiment in which an interval circuit 43 is added to the oscillation circuit 41. This interval circuit 43 is a circuit which does not operate for 50 minutes, starts operation thereafter and continues operation for 50 minutes, as shown in the output waveform of FIG. 5 (b). In the non-operation state, the oscillation circuit 41 operates and enters an oscillation period I. In the operation state of the circuit 43, the oscillation circuit 41 stops its oscillation operation and enters a stop period II.
The whole is configured by repeating II.
Wherein as the oscillation period I seen in the antenna input voltage waveform of FIG. (A), T ₁ is ON duration that takes place of the actual oscillation of the oscillation period I, is a 0.5 msec, in the interval T _1, the The sine wave shown in FIG. 6 oscillates at f = 1 / t = 100 KHz to several tens of MHz. OFF T ₂ is not the place of oscillation
The section is set to 1 msec, and the heat generated by the coil and the like in the apparatus is a section for suppressing heat generation due to induction heating in a living body.

As described above, in the blood circulation promoting device according to the present invention, the oscillation circuit, when using the device, the oscillation period is limited to a constant,
Other than during the same period, the oscillation is controlled so as to be stopped within a range in which the irradiation of the electromagnetic field from the electromagnetic field generating means can be continued. The current does not flow by an amount corresponding to the section, and as shown in the above-described embodiment, the battery life can be extended for about two times. In the rechargeable type,
Usually, the capacity of the rechargeable battery is considerably limited. In such a case, it is particularly effective that the long-term use is possible.

In the above-described embodiment, the interval time is set to 50 minutes. However, the interval time may be set slightly fluctuating, for example, from 1 minute to 2.3 hours. In this case, the same operation and effect as described above can be expected. It is supposed to be. The numerical values such as the rate of change of the blood vessel diameter are not limited to those in the above embodiment. The rechargeable battery may be a normal dry battery.

〔The invention's effect〕

Since the blood circulation promoting device according to the present invention is configured as described above, the battery can be used for a long time.
