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. 1465, and a cordless type as described in, for example, Japanese Patent Application Laid-Open No. 2-80060.

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. The main body of this treatment device is small enough to fit in the palm of your hand.A conductive adhesive pad made of hydrogel is attached to each of the picture electrode plates of the main body of the treatment device.

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 about 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 conductive electricity is placed on these electrode plates. A sticky adhesive 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,
Since 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, there is a wide gap between the output electrodes, and there is no tingling sensation and the stimulation is felt strongly, 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.

In this method, the treatment device body is divided into two detachable divided body parts each having an output electrode, and these divided body parts are connected to each other by an electric cord, and one of the divided body parts is connected to the circuit part and the operation part. A cord reel for winding and storing the electric cord and a battery are disposed in the other split main body, and the cord reel and battery are integrated.

(Function) When the low frequency treatment device of the present invention is used as a corded type, the two divided main body parts are separated from each other, and
An electric cord is appropriately unwound and extended from a cord reel in one divided main body. Then, the two main body parts each having an output electrode are separated from each other by an appropriate distance and are respectively attached to the treatment site of the human body. That is, when used as a corded type, the distance between the output electrodes can be made sufficiently large and can be set arbitrarily, and it is possible to eliminate the tingling sensation and obtain a sufficient stimulation sensation for any treatment area. On the other hand, when used as a cordless type, an electric cord is wound up and stored on a cord reel, and both body parts are connected to each other. Moreover,

Further, the negative output end of the pulse output circuit of this circuit section is electrically connected to the negative output electrode 14 of the first divided main body section I6 via the single core wire 17c in the electric cord 17 and the sliding contact 51. It is connected.

Next, the operation of the above embodiment will be explained.

When the low frequency treatment device is used as a corded type, the connecting portions 31.55 of the two main body parts 15.16 are removed from each other to separate the two main body parts 15.16 from each other. At the same time, the electric cord 17 is appropriately unwound from the cord reel 44 in the second divided main body portion 16 and stretched. At that time, if the two main body parts 15 and 16 are separated from each other, the cord reel 44 will rotate and the cord reel 44 will rotate.
An electrical cord 17 is unwound from it. Then, by placing the main body parts 15.16 on both sides at an appropriate distance and pasting the conductive adhesive pads 30.54 of those output electrodes 13.14 on the human body, the main body parts 15.16 on both sides are It is attached to each treatment site of the human body, for example, both shoulders.

Then, using the battery 12 in the second divided main body section 16 as a power source, electrical therapeutic pulses generated by the circuit section in the first divided main body section 15 are applied to the human body from the output electrodes 13.14 at a low frequency. Ru. This provides stimulation to the human body and provides treatment.

Note that the user can switch the waveform of the therapeutic pulse to be output by operating the waveform switching knob 26 on the first divided main body section 15.

Moreover, by operating the intensity adjustment button 27, the voltage of the therapeutic pulse can be adjusted, and the intensity of stimulation can be adjusted.

When used as a corded type as described above, the distance between both output electrodes 13 and 14 can be sufficiently increased and can be set arbitrarily.

As a result, it is possible to treat any two treatment sites, and also to eliminate the prickling sensation and provide a sufficient stimulation sensation to the treatment sites.

Further, even when using the corded type, the electric cord 17 can be pulled out only by the required length, so that the electric cord 17 can be kept out of the way as much as possible.

On the other hand, when using the low frequency treatment device as a cordless type, the cord reel 4 in the second divided main body portion 16
The electric cord 17 is wound up and stored in the coil 4, and the two main body parts 15 and 16 are connected to each other. At this time, when the battery cover 43 is rotated with respect to the cases 41 and 42, the cord reel 44 rotates together with the battery cover 43, and the electric cord 17 is wound around the cord reel 44. Furthermore, by engaging the connecting portions 31.55 of the two main body parts 15.16, the two main body parts 15.16 are coupled to each other.

Then, these divided main body parts 15.16 and their output electrodes 13.14 are attached to a human body to perform treatment. This is the same as when using it as a corded type.

In the case of the cordless type as described above, the electric cord 17 does not get in the way at all.

Furthermore, since the two main body portions 15 and 16 are integrated, handling becomes easier.

Note that when replacing the battery 12, after removing the battery cover 43, the battery 12 is removed from the cord reel 44, and a new battery 12 is inserted into the fitting part 47 of the cord reel 44.
After that, the battery cover 43 is fitted.

Thus, according to the above configuration, it is possible to provide a small, lightweight low-frequency treatment device that is comfortable to use and takes advantage of both the cordless type and the corded type.

In addition, there are two divided main body parts 15. 16, the first divided main body part 15 has a waveform switching knob 2 which is a circuit part and an operation part.
6 and the strength adjustment button 27 are arranged, and the battery 12 and the cord reel 44 are arranged in the second divided main body part 16, so that the weight and size of the two main body parts 15 and 16 are well balanced. I can do it. That is, the main body portion 1 on both sides
By arranging various parts in a well-balanced manner in 5.16, space can be used effectively, and both main body parts 15
．． 16 are the same size, therefore both output electrodes 13. 14 to the same size, split main body part 1
5.16 can be made as small as possible. Along with this, the weight balance is also improved, which improves ease of use. Further, it is possible to use a battery -16=12 that is as large as possible and has a large capacity.

By the way, if the battery 12 is integrated with the cases 41 and 42 instead of the cord reel 44, there will be a problem that the number of sliding parts will increase, the mechanism will become complicated, and the size will increase. For example, at least one pair of sliding contacts is required between the battery 12 and the electrical cord 17.

However, according to the above configuration, since the battery 12 is integrated with the cord reel 44, there is no need for a sliding contact at least between the battery 12 and the electric cord 17.

In addition, since the metal plate 52 of the output electrode 14 of the second divided main body part 16 itself is used as a sliding contact, the mechanism is simplified, space can be used more effectively, miniaturization can be achieved, and costs can be reduced. can. Reliability is also increased due to fewer sliding contacts.

Note that instead of fixing the output electrode 14 to the cases 41 and 42 as in the previous embodiment, the lower surface of the cord reel is exposed through the lower opening of the lower case, and the output electrode is fixed to the lower surface of the cord reel. It may also be provided. This structure eliminates the need for sliding contacts at all.

〔Effect of the invention〕

According to the present invention, it is possible to provide a compact and lightweight low-frequency treatment device that is comfortable to use and takes advantage of both the cordless type and the corded type. In other words, as a corded type, by arbitrarily setting the distance between multiple output electrodes, it is possible to eliminate the tingling sensation and obtain a sufficient stimulation sensation for any desired treatment area. As a cordless type, you can keep the electrical cord out of the way and also make it easier to handle. In addition, the circuit section and operation section are placed in one split main body, and the cord reel and battery are placed in the other split main body, making it possible to effectively utilize the space inside the main body on both sides. The weight and size of the main body are better balanced, and handling is also improved. Furthermore, since the cord reel and battery are integrated, the number of sliding contacts can be reduced, reliability is improved, space can be used more effectively, and costs can be reduced.
