Description

  The present invention is a home-use electrotherapy device in the form of a futon that can perform electric potential treatment while heating with a heating function in an electric potential / heat combination home medical device capable of performing electric potential treatment and thermal treatment.

Technology background

From the viewpoint of safety, home medical devices have basic restrictions such as not being able to use two kinds of treatment functions at the same time and having to set a treatment time rating.

However, this kind of combined potential / heat combination home medical device is often used as a sleeping mattress because it is used while sleeping. There is a risk of low temperature burns due to the high temperature when going to bed while taking heat treatment. Therefore, the treatment time must be limited so that the treatment is forcibly stopped after 8 hours at the longest.

However, when stopped by time, when used by a person such as a bedridden elderly person, it becomes cold and unusable during the winter, and it is cold and unusable when using electric potential therapy in the winter.

  The present invention is a combination of electric potential and heat having two functions of electric potential treatment and thermotherapy, and in a home medical device, a regulated thermotherapy temperature range (40 ° C. to 60 ° C.) that exhibits the effect of the thermo treatment, By separating the warming temperature zone below 40 ° C, which has no therapeutic effect, the warming temperature zone has functions such as being heated even when using potential therapy without any restriction of 8 hours. Therefore, it is an object of the present invention to provide a home-use electrotherapy device in the form of a futon which does not impair the basic restrictions on the function as a home medical device and does not have the above-mentioned inconvenience even when used for sleeping.

  The present invention provides a microcomputer equipped with a temperature sensor such as a heat-sensitive wire on a heating element, and an electrical signal generated by an impedance change that changes according to the temperature sent from the temperature sensor is received on the controller side. Heating is performed by separating and controlling the temperature of the heating element so that the surface of the mattress is in the thermal treatment temperature range of 40 ° C to less than 60 ° C and the heating temperature range of less than 40 ° C. When the temperature range is less than 40 ° C., the use time can be unlimited, and heating can be performed even when using electric potential therapy. In other words, as a home electric potential therapy device and a home thermotherapy device, both functions are provided in a single futon, but even if it is used for sleeping, it does not have the above-mentioned usability problems. It is intended to provide an electrotherapy device.

An embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view showing the overall appearance of a home-use electrotherapy device in the form of a mattress. It consists of a mattress 1 mm wide, 2 m long, 30 mm to 50 mm thick, and a controller unit 2 for electrical control. ing.

The mattress 1 has an internal configuration shown in FIG. 2, and this internal configuration is encapsulated in a front outer skin 3 made of a polyester fabric as an outer skin and a back outer skin 4. Inside the outer skin, a polyester hard cotton 5 as a cushioning material is installed and protected by this polyester hard cotton 5, a set of electrical parts such as an electric floor board 6, a surface sensor 7, a heating element 8 and a heat sensitive wire 9 is provided. Has been.

The electric floor board 6 is obtained by coating a conductive paint such as a carbon paint on a vinyl chloride film, for example. By applying a DC voltage of, for example, minus 600 V or minus 300 V to the electric floor board 6, potential treatment is performed.

In addition, when the surface sensor 7 is accidentally pierced with a sharp metal object such as a needle during use and the electrical insulation of the heating element 8 is damaged, the safety circuit provided in the controller unit 2) is activated. In this case, the power supply to the heating element 8 is cut off to prevent accidents such as electric shock and short circuit.

  As shown in FIG. 3, the heating element 8 is formed by impregnating and applying a conductive paint such as carbon paint to a cloth woven with electrode wires 10 and 10 on both sides, and covering the conductive portion with an electric insulating film such as a vinyl chloride film. A planar heating element is used that is in close contact with the package. A heat sensitive wire 9 is wired to the heating element 8 in a meandering manner. The heat sensitive wire 9 is formed by arranging a temperature sensitive resin mainly composed of vinyl chloride around the core wire, providing an outer wire on the outer periphery of the temperature sensitive resin, and electrically insulating with vinyl chloride. Thus, by connecting one of the alternating current electricity to one of the core wire and the outer wire, an electrical signal such as a leakage current to the other wire through the temperature sensitive resin obtained by the impedance change that changes due to the temperature change of the heating element 8. Is received by the controller to control any set temperature. Polyester cotton 11 is installed on the back surface of the heating element 8 as a heat insulating material.

The controller unit 2 in which a microcomputer is incorporated is electrically connected to the mattress 1 configured as described above by a main body cord 12 and a connector 13.

The controller unit 2 receives an electrical signal from the heat sensitive wire 9 and separates the heat generation temperature of the heating element 8 into a heat treatment temperature range of 40 ° C. to 60 ° C. and a heating temperature range of less than 40 ° C. by microcomputer control. Control. For example, in the thermotherapy temperature range, the temperature is controlled to be “strong” at 50 ° C. and “weak” at 45 ° C. In the warming temperature range, high to low temperature control is performed in a plurality of steps (four steps in this embodiment) at less than 40 ° C.

The operation will be described based on the operation surface diagram of the controller unit 2 in FIG. When using as a thermal therapy, the power switch a is operated to turn on the power. The power LED indicator lamp b indicating the power ON state is lit. Next, when the thermal treatment button c in the figure is pressed once, the “strong” potential LED display lamp d is turned on, and thermal treatment at a high temperature of 50 ° C. is executed. When the button is pressed twice, the “weak” potential LED display lamp e is turned on, and a low temperature thermotherapy of 45 ° C. is executed. These thermal treatments are timers built into the microcomputer software, and the power supply to the heating element 8 is forcibly stopped after 8 hours from the start of treatment. Press the button three times to stop treatment within 8 hours. During the use of this thermal therapy, the other warming buttons f and potential therapy buttons g are inoperable.

Further, when used as potential treatment, the power switch a is operated to turn on the power. As described above, the power LED display lamp b is lit. Next, when the potential treatment button g is pressed once, the “strong” potential LED display lamp h is turned on, a DC voltage of minus 600 V is applied to the electric floor plate 6, and the potential treatment of the potential “strong” is executed. When the button is pressed twice, the “weak” potential LED display lamp i is turned on, a DC voltage of −300 V is applied to the electric floor plate 6, and the potential treatment of the potential “weak” is executed. As described above, in the case of these potential treatments, the voltage application to the electroplating board 6 is forcibly stopped after 4 hours from the start of the treatment in the case of “strong” treatment, and forcibly after 8 hours in the case of “weak” treatment. Thus, the voltage application to the electric floor plate 6 is stopped. If you want to stop the potential treatment within 8 hours or 4 hours, press button g three times.

Power switch a to perform heating below 40 ° C without thermotherapy effect
Operate to turn on the power. As described above, the power LED display lamp b is lit. Next, when the heating button f is pressed once, heating is performed at an arbitrary “low” temperature (for example, 26 ° C.), and the “low” LED display lamp j is turned on. When pressed twice, the temperature is increased by one rank (for example, 30 ° C.), and the second LED indicator lamp k is turned on. When pressed three times, a temperature two ranks higher (for example, 34 ° C.) is executed, and the third LED indicator lamp l is turned on. When pressed four times, a high temperature is executed by three ranks higher (for example, 38 ° C.), a “high” LED display lamp m is lit, and an arbitrary temperature can be selected. When pressed 5 times, heating is turned off.

These operation buttons c, f, and g are operated as a toggle. During the warming operation, it is possible to execute electric potential therapy. That is, only potential treatment and only heating can be performed, and potential treatment can be performed while heating.

  According to the present invention, in this type of home electrotherapy device that regulates the prohibition of simultaneous use of two types of treatment, b, the rating of treatment time (forced stop), the thermotherapy temperature range ( 40 to 60 degrees Celsius) and the heating temperature range (below 40 degrees Celsius) are controlled separately, so two types of treatments like a combination of potential and heat household medical devices are used as a single futon Even if it is used for sleeping, it can be used as a warm bed and in a warm potential treatment device in winter. In other words, even though it is a medical device that maintains the standard as a medical device, if it is used with heating, even if it is used by a bedridden elderly person or a sick person, there is no worry of low temperature burns and it can be used for a long time, In addition, when electric potential treatment is used in winter, it is possible to provide an extremely easy-to-use product that can be used while being warmed.
