Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a low-frequency treatment device, which is a home health medical device, and which uses low-frequency pulses to relieve stiff shoulders and the like.

(Prior art) Low frequency treatment devices can be roughly divided into
There are a corded type as described in Japanese Patent Publication No. 465, and a cordless type as described in, for example, Japanese Unexamined Patent Publication No. 2-HQ6Q.

A cordless type low-frequency treatment device has a circuit section including a power supply, a pulse generation circuit, a pulse output circuit, and its control circuit, a waveform changeover switch for operating this circuit section, and a switch for adjusting the intensity of the output waveform. An operating section such as a power adjustment button and a pair of positive and negative electrode plates connected to the circuit section are all provided within the treatment device main body. This treatment device itself has become small enough to fit in the palm of your hand. Note that conductive adhesive pads made of hydrous gel are attached to each of the picture electrode plates of the treatment device body.

When using the cordless low-frequency treatment device, the device itself is applied directly to the treatment area of the human body using a pair of conductive adhesive pads that serve as output electrodes to perform treatment and relieve stiff shoulders.

On the other hand, a corded type low frequency treatment device has a circuit section including a power supply, a pulse generation circuit, a pulse output circuit, and its control circuit, a waveform and speed switching button for operating this circuit section, and a button for changing the output waveform. An operation section such as a strength adjustment dial for adjusting the strength is provided inside the treatment device body. However, the output electrode that is attached to the human body is provided in a conductor section that is separate from the main body of the treatment device. This conductor part has a conductor cord of approximately 1 m length with one end connected to a pin plug, and a pair of electrode plates provided at the other end of the conductor cord, and a conductive conductor is placed on these electrode plates. A sticky pad is attached to each.

In a corded type low frequency treatment device, the circuit section of the treatment device main body and the electrode plate of the conductor portion are electrically connected by inserting the pin plug of the conductor portion into the jack of the treatment device main body. Then, by applying a pair of conductive adhesive pads to, for example, the left and right shoulders, treatment can be performed.

The above-mentioned cordless type low frequency treatment device is small and lightweight, so it can be used by simply attaching the treatment device body directly to the treatment area of the human body.
Treatment can be performed, but because the distance between the positive and negative output electrodes is narrow, the current does not pass through the inside of the human body, which is effective for treatment.
Easily passes through the skin surface. Therefore, if the output is increased in order to obtain a sufficient stimulation sensation that is effective for treatment, a prickling pain may be felt.

On the other hand, the corded type low frequency treatment device,
The positive and negative pairs of output electrodes that are actually applied to the treatment area of the human body are located on the extension of the branched conductor cord, so there is a wide gap between the output electrodes, there is no tingling sensation, and the stimulation is strong, allowing for comfortable treatment. can be done. However, the need for a conductor cord and a treatment device body in addition to the output electrode portion that is actually pasted on the treatment site is cumbersome in use. That is, the conductor cord gets in the way, and the treatment device itself must be held in the hand or kept in a shirt pocket during use, which is cumbersome.

(Problems to be Solved by the Invention) As mentioned above, the conventional cordless type low frequency treatment device and the corded type low frequency treatment device each have advantages, but also have disadvantages. Ta.

Therefore, an object of the present invention is to provide a compact, lightweight low-frequency treatment device that is easy to use and takes advantage of both the cordless type and the corded type.
