Description

The present invention is a combination of electric potential and heat that can be used for electric potential treatment that adjusts the charged fine particles of the human body by lying down on a negative electric field and thermal treatment that improves blood circulation and softens the stiff shoulders by warming the human body. It relates to a treatment device.

An electric potential therapy device is a type of home-use electrotherapy device that adjusts charged particles in a living body by placing a human body in an electric field region formed by applying a negative voltage to a ground-insulated electric floor plate. The device is a type of home thermotherapy device that warms the human body with a warming body such as an electric heating element to improve blood circulation and soothe stiff shoulders and muscle pain. Conventionally, a combination of these treatment devices is configured for a mattress so that treatment can be performed while sleeping.

The present invention shares the electric floor plate and the conventional surface sensor provided to detect a failure such as needle stick of a conventional surface heating element and use it safely in the electric potential / heat combination home electrotherapy device as described above. Accordingly, the present invention is intended to provide a home-use electric therapy device with a combination of electric potential and heat that has a simple structure, is lightweight, and can be provided inexpensively.

The surface heating element has a risk of electric shock when a metal piece such as a needle is stuck. For this reason, in order to avoid the danger, this type of product using a surface heating element is provided with a surface sensor made of a safety upper surface conductor. In this type of treatment device in which an electric potential treatment device is combined with a conventional hyperthermia treatment device, the surface sensor and an electric floor plate having substantially the same area as the surface sensor are doubled. The reason is that the surface sensor is a planar electrode intended to cause an abnormal current to flow from the surface sensor when detecting the electrical insulation deterioration of the surface heating element and the conductive foreign matter, while the electric floor plate is -100V for the purpose of potential treatment. This is because it is a planar electrode for applying a negative voltage of about -1000 V, and both electrodes are used for constituting a completely independent function on an electric circuit. Therefore, conventionally, the surface sensor and the electric floor plate have not been used as a common electrode.

In addition, in this conventional electric potential treatment device with a surface sensor as an electrical safety combined with this kind of potential / thermal heat, the circuit for generating a negative potential is configured to directly boost from a commercial power source (AC100V). If the electric floor plate is made common, the negative potential voltage becomes unstable due to the influence of the leakage current from AC100V, making it difficult to make common.

In view of these points, the present invention is a stable DC voltage that is insulated and converted from a commercial AC power source, and the DC voltage output is electrically connected to the commercial AC power source via a high impedance circuit. By boosting a DC voltage having a configuration capable of transmitting the ground reference potential level to the DC voltage output, and applying it to the electric floor plate as a negative voltage for potential treatment, the electric potential between the boosted negative voltage and the surface sensor function is increased. Can prevent the mutual interference and can supply a stable negative voltage to the electric floor plate even when the function of the surface sensor is maintained. It is possible to provide a lightweight and inexpensive treatment device by using a sensor and an electric floor plate as an electrode of an electric potential treatment device.

According to the present invention, the surface sensor necessary for the safe use of the planar heating element is shared with the electric floor plate of the electric potential treatment device, so that the structure is simplified and lightweight, and the cost is reduced.

A voltage output monitoring function, which is a potential voltage detection circuit, is provided on the voltage output side to the electric floor plate, and a light output diode is blinked by the microcomputer by outputting a voltage output enable / disable signal to the microcomputer. A surface sensor that also serves as an electric floor plate stops the supply of electricity to the planar heating element by the action of the microcomputer when a leakage current (for example, 100 μA or more) from the planar heating element is received from the planar heating element. In addition, the low voltage minus voltage applied to the electric floor plate that also functions as a surface sensor is a DC power source converted in a state insulated from the commercial AC power source, and boosts the DC power source connected to the commercial AC power source with high impedance. This is the voltage obtained.

    An embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a sheet heating element 1 for carrying out the present invention, in which a carbon conductive paint is applied to a woven fabric provided with electrode bands 2 and 2 woven with copper wires on both sides, and the front and back surfaces are coated. It is formed by laminating a PVC film and electrically insulating it. Lead wires 4, 4 are led out from the electrode strips 2, 2 via terminals 3, 3. FIG. 2 shows an electric floor plate 5 also serving as a surface sensor, which is formed by forming a conductive surface 7 formed by printing a carbon conductive paint or attaching a carbon conductive film on one side of an electrically insulating film 6 such as a vinyl chloride film. The lead wire 9 is led out from the terminal 7 through the terminal 8.

  The planar heating element 1 and the electric floor plate 5 are integrally formed with the conductive surface 7 of the electric floor plate 5 facing one side of the planar heating element 1.

    The sheet heating element 2 and the electric floor board 5 formed integrally with each other are bonded to the cotton of the mattress 10 as shown in FIG. An electrical connector 11 is attached to the corner portion of the mattress 10, and the sheet heating element 1 and the lead wires 4 and 9 of the electric floor plate 5 are electrically connected to the controller 13 through the main body cord 12 from there. Reference numeral 14 denotes a power cord with a plug connected to a commercial AC power source.

    The controller 13 is provided with a temperature control button 15 for controlling the heat generation temperature of the planar heating element, a light emitting diode 16 for knowing the temperature control setting, a potential / heat switching button 17 and a light emitting diode 18 for knowing the treatment status on the operation surface. is there.

    FIG. 4 shows a cross section of the mattress 10 part of FIG. 3 in which the electric / heat combination home electrotherapy device of the present invention is implemented in the form of a mattress, and is sandwiched between upper and lower cottons 20 and 20 encased in outer skins 19 and 19. A laminated sheet heating element 1 and an electric floor plate 5 are provided.

    FIG. 5 is an electronic circuit block diagram housed in the controller 13 showing the electrical system. The commercial AC power supply (100 V to 220 V) is supplied to the switching stabilization power supply circuit A and the heating element control circuit B that controls the electric supply to the planar heating element 1.

In the power supply circuit A, it is converted into, for example, direct current 5V by a switching stabilized power supply, and supplied to the microcomputer C and the negative potential generation circuit D for potential treatment. In the negative potential generating circuit D, for example, it is boosted to negative DC 600V and is electrically connected to the electric floor plate 5. The switching stabilization power supply circuit and the commercial AC power supply are basically insulated, but by connecting the DC output to the commercial AC power supply via the high impedance element G, the output reference of the negative potential generating circuit D is commercialized. The ground potential of the AC power supply can be set.

  A voltage detection circuit E is provided on the negative voltage output side to the electric floor plate 5, and a voltage application state is input to the microcomputer C. In the microcomputer C, ON / OFF control to the negative potential generation circuit D and ON / OFF to the heating element control circuit B are supplied from a temperature sensor (heat sensitive line or thermistor) (not shown) provided in the sheet heating element 1. Performed in response to a signal.

In this case, when the voltage output cannot be detected by the potential voltage detection circuit E even though the signal from the microcomputer C to the minus potential generation circuit D is ON, the light emitting diode 16 or 18 is flashed via the microcomputer C. Inform.

In addition, a leakage current detection circuit F is provided on the potential voltage output circuit to the electric floor plate 5 so that, for example, a needle stick or an electrical insulation film of the planar heating element 1 is insulated from the planar heating element 1. By detecting the leakage current received at the terminal and transmitting it to the microcomputer C, the energization of the planar heating element 1 is turned off to establish safety in use. In this case, the potential treatment voltage to the electric floor plate 5 is boosted from the direct current 5 V after the switching stabilized power supply circuit A, so that it is differentiated from the leakage current of the commercial AC power source to the planar heating element 1. Can also be used as a surface sensor.

  In the above embodiment, a planar heating element formed by applying a conductive paint such as carbon to a woven cloth in which electrode bands are woven on both sides is used in the description. The same effect can be obtained with a linear heating element woven into a weft.

  As described in the above embodiments, the present invention increases the negative DC potential voltage from the switching stabilized power supply, so that the electric floor plate and the surface sensor can be shared by the same planar conductor. As a result, the structure becomes simple and inexpensive.
