Description

A low-power wearable electromagnetic ultrasonic medicinal moxibustion device

technical field

The invention belongs to the fields of electromagnetism and health care, in particular to a wearable medicinal moxibustion device with low power consumption based on electromagnetic ultrasound.

Background technique

"Moxibustion" is a treatment method in traditional Chinese medicine. It usually refers to the use of heat sources to stimulate acupoints or a certain part of the body to achieve the purpose of treatment and health care. "Moxibustion" is similar to the concept of hot compress that we usually call. Modern medicine also believes that this method has the effect of dilating blood vessels, improving local blood circulation, and promoting local metabolism. Tendon softness, etc. have a good auxiliary therapeutic effect. "Medicated moxibustion" is supplemented with medicine during the heat moxibustion process, which can make the medicine go directly to the affected area and make the medicine effect fully absorbed by human tissues.

The hot moxibustion method in traditional Chinese medicine usually uses moxa leaves to make moxa sticks or moxa rolls, and burns or smokes the human body. This method uses an open flame and requires a professional doctor to operate. Improper use can easily cause burns or even fire. And traditional heat moxibustion requires the patient to keep lying down and other postures, and cannot move freely during treatment. Modern hot compress can be regarded as another form of hot moxibustion, usually using preheated items, such as hot towels, hot salt packs, hot sandbags, etc. to thermally stimulate human tissues. However, this hot compress device will gradually cool down as the hot compress is carried out, and cannot achieve a constant temperature.

In order to further popularize the thermal moxibustion method in family medical care, the thermal moxibustion device should have the requirements of constant temperature controllability, safety, and convenience. In addition, modern medicine believes that the magnetic field can affect the movement of charged particles, the orientation of biopolymer magnetic moments, the permeability of membrane systems, and the distribution of human body currents, etc., so that the physiological and biochemical processes of human tissue cells are slightly changed, thereby promoting blood circulation. And lymphatic circulation, analgesia, swelling and other effects. Therefore, the thermal moxibustion device combined with magnetic therapy can further improve the effect of medical care.

Existing patent has also provided some novel hot compress devices. They achieve this by electric heating, and some have also added magnetic therapy devices, such as the published invention patents "Electric Hot Compress Ointment Sticker" (CN104323882A), "Fitness Magnetic Electric Hot Compress Therapy Apparatus" (CN101023897A), but these devices need to be connected Household AC power supply, can not move freely when in use, very inconvenient. And there is a risk of electric shock if the household AC is used improperly. In addition, in the existing magnetic therapy and thermal moxibustion devices, the source of magnetic energy is usually a permanent magnet. However, the magnetic field of the permanent magnet is a constant magnetic field rather than an alternating magnetic field, which has very limited effects on promoting the movement of charged particles in the human body, promoting blood circulation, and stimulating acupuncture points.

Summarize the existing thermal moxibustion device, mainly by the following deficiencies:

(1) The traditional thermal moxibustion method using burning, smoking and roasting can easily cause burns or even fire, and requires high professionalism in operation, which is not conducive to popularization.

(2) The temperature of the preheating type hot compress device will gradually decrease when it is used, which will affect the effect of hot compress, and it is very inconvenient to use it repeatedly.

(3) The energized hot compress device uses household AC power supply, so it is inconvenient to move when using it, and there is a risk of electric shock.

(4) Existing hot compress devices with magnetic therapy effects usually add permanent magnets, the magnetic field is constant, and the effect of magnetic therapy is limited.

detailed description

The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and examples of implementation, but the implementation and protection of the present invention are not limited thereto.

FIG. 1 is a structural diagram of an example of the device, which are respectively from top to bottom: a flexible PCB coil layer 101 , a metal sheet heat dissipation layer 201 , and a plaster layer 301 .

A hollow 103 is provided in the flexible PCB coil layer 101 to facilitate placement of the central control module 203 protruding from the metal heat sink layer. The coils 102 can be distributed elsewhere, and the number and positions thereof are not limited to the pattern shown in the example figure. Since the coil is the wiring of the PCB circuit board, the shape, line width, number of turns, etc. of the helix can be flexibly adjusted during design, as well as parameters such as the resistance and inductance of the coil.

The metal sheet heat dissipation layer 201 is generally made of stainless steel sheet or copper sheet, and its thickness should make the whole have good flexibility. A central control module 203 is installed on the heat dissipation layer of the metal sheet, which generally includes MCU, power amplifier and other components. The metal heat sink layer is also provided with hollows 202, the number and positions of which correspond to the number and positions of the helical coils of the PCB coil layer, so as to ensure that the magnetic field and heat energy emitted by the coils can directly reach the human tissue when radiating downward.

A heat insulating material is provided at the junction between the metal sheet heat sink layer and the flexible PCB coil layer, so that the heat can be conducted toward the human tissue as much as possible. A self-adhesive layer is coated on the device between the device and the plaster, so as to facilitate the fixing of the medicinal moxibustion device and the plaster and repeated use after replacing the plaster.

The flexible PCB coil layer in the medicinal moxibustion device described in this example can generate an alternating magnetic field, and at the same time, due to the impedance of the coil, it will also generate heat during operation. Therefore, the magnetic energy and thermal energy generated by the coil are used to perform magnetic therapy and thermal moxibustion on human tissues, instead of the traditional fumigation of moxa sticks or moxa rolls.

The central control module is closely attached to the center of the heat dissipation metal sheet, which is beneficial to fully export the heat of the central control module when it is working, and serves as a part of the heat source of moxibustion. This not only dissipates heat for the central control module to avoid overheating, but also can use the waste heat for thermal moxibustion. In combination with the self-heating of the above-mentioned spiral coil, it can meet the needs of thermal moxibustion without additional heating devices, reducing the cost and power consumption of the device. . The metal heat sink is a thin metal sheet, such as a stainless steel sheet, and its thickness should ensure that the device as a whole has good bendability and flexibility.

The MCU is responsible for the emission of electromagnetic ultrasonic signals and power control, and is connected to the flexible PCB coil through a power amplifier to generate an oscillating magnetic field of ultrasonic frequency to achieve the effect of magnetic therapy. At the same time, the flexible PCB coil will also generate a certain amount of heat energy, which serves as another source of heat for moxibustion. The thermal sensor is used to sense the temperature of the thermal moxibustion device, and feeds back the temperature information to the MCU, and realizes electronic temperature control through the MCU.

The thermal moxibustion device is provided with a plaster layer, and the plaster can use different medicinal components according to actual disease requirements, and combine with the device to realize the multiple effects of magnetic therapy and medicinal moxibustion.

As above, the present invention can be better realized and the technical effects described in the summary of the invention can be obtained.
