BRIEF SUMMARY
DESCRIPTION
1. Technical Field
The present invention relates to a small-sized low frequency curing apparatus capable of providing an electrical stimulation subject such as an organism with a required electrical stimulation regardless of a small capacity of a power supply and, in particular, to a small-sized low frequency curing apparatus which can be applied directly to the organism and can be produced in a smallest possible size.
2. Background Art
Conventionally, there has been provided and employed an endermic electrical stimulation apparatus, i.e., a so-called low frequency curing apparatus, which has a size such that it is portable and can be applied. However, an apparatus which has a light weight and a size such that it requires no lead line and can be applied to the skin like a bandage, a poultice and the like has not yet been provided. To provide an apparatus which has a light weight and a size such that it can be applied to the skin, as a power supply thereof, a micro battery or small-sized battery such as a button battery, a paper battery and the like must be used. When a small-sized power supply is used, however, the following problems inevitably arise. That is, a skin impedance represents a high resistance value, due to the tissue structure, and accordingly, the application of low frequency high voltage is necessary to supply a cenesthesic low frequency stimulation current, and a boosting means is necessary to generate a high voltage from a low power supply voltage. Cenesthesic electrical stimulation requires a predetermined voltage value and current value. In a small-sized power supply such as a small-sized battery, however, the internal impedance is increased as the discharge current is increased. Accordingly, it is difficult to realize the above conditions.
It has been considered that the above problems can be solved by employing a method including the steps of accumulating battery energy to an extent such that stimulation can be applied to the organism, and discharging this accumulated energy. To effect the setting of the timing of the charge and discharge, or the operation thereof, several active elements are needed, but in many cases, to actually operate such active elements, a supply of a stable required electrical energy is necessary. Therefore, it is almost impossible to meet these conditions by employing the energy of a small-sized battery or a boosted energy obtained by boosting said energy, in the light of the duration time of the battery energy and the battery capacity. Still further, under the conditions of an unstable voltage, a drawback arises in that excessive energy is discharged and dissipated. Accordingly, a practical low frequency curing apparatus using a small-sized battery has not yet been provided.
DISCLOSURE OF THE INVENTION
An object of the present invention is to provide a small-sized low frequency curing apparatus capable of applying cenesthesic electrical stimulation to an organism even though it is constituted from a small number of elements.
Another object of the present invention is to provide a small-sized low frequency curing apparatus capable of supplying long-time and stable electrical stimulation irrespective of the amount of energy of a small-sized power supply.
The above-mentioned objects can be attained by providing a small-sized low frequency curing apparatus comprising: a small-sized power source; boosted pulse generating means for generating a train of boosted pulses upon a receipt of electrical energy from the small-sized power source; accumulating means constituted to receive a train of pulses from the boosted pulse generating means and accumulate electrical energy at least to a predetermined amount at which stimulation effective for an object to be electrically stimulated is reached; and a low frequency pulse outputting means for outputting low frequency pulses when the predetermined amount of electrical energy accumulated in the accumulating means reaches a level at which stimulation is possible for the object to be stimulated.
