Problems solved by technology

However, using this method also determines that the patient needs to be placed in the middle of the coil during use, resulting in bulky equipment that is not easy to move, and it is difficult to carry out health care and treatment at home
In addition, this technology requires continuous treatment for a long time, and the PEMF magnetic field often cannot bring intuitive experience to patients, which makes many patients lose the patience to continue treatment during the long-term boring treatment, and the use of magnetic field alone cannot relieve the pain of patients. Muscle fatigue, soreness and other problems make it difficult for previous equipment to achieve better therapeutic effects

Embodiment 1

[0015] Example 1. see figure 1 , the present embodiment provides a structure of a physiotherapy chair based on a pulsed magnetic field. Pulsed magnetic field coil structure such as figure 2 As shown, it is composed of coil 2-1, spring 2-2, permanent magnet 2-3, coating 2-4.

[0016] After the pulsed magnetic field coil is energized, the waveform generating device in the peripheral circuit 5 will input a pulse current of appropriate frequency to it, and the coil will generate a pulsed magnetic field under the action of this current, and the permanent magnet will hit the spring 2 in the coil under the action of the magnetic force. With rectangular wave or square wave current, when no current or reverse current occurs, under the action of spring force and magnetic force, the permanent magnet will hit the coating 4 in the opposite direction. Under the action of periodic current, the permanent magnet will continue to do this periodic motion under the action of magnetic force an...

Embodiment 2

[0018] Example 2. In this embodiment, the structure of the pulsed magnetic field coil is as Figure 4 As shown, the rest of the structure is the same as in Example 1. The peripheral circuit will input a pulse signal of appropriate frequency to it, and the coil will generate a pulse magnetic field under the action of this current. The polarity of the magnetic field at a certain moment is as follows: Figure 4 marked. The permanent magnet 4-3 hits the coating 4-4 ​​under the action of the magnetic force, and when the current is reversed, the permanent magnet 4-3 moves in the opposite direction under the action of the magnetic force. Since the permanent magnet 4-1 at the bottom of the coil is magnetically opposite to the permanent magnet 4-3, the two permanent magnets will repel each other. As the two permanent magnets approach, the repulsive force will gradually increase, making the permanent magnet 4-3 slow down. Slow, and eventually bounced back magnetically. After the nex...

Embodiment 3

[0019] Example 3. In this embodiment, except that the structure of the pulsed magnetic field coil is different, the rest of the structure is the same as that of Embodiment 1. The pulsed magnetic field coil structure of the present embodiment is as Figure 5 As shown, its structure includes a permanent magnet 5-1 that acts as a buffer, an electromagnetic coil 5-2, two permanent magnets 5-4 and 5-6 with opposite magnetic properties, and a connecting rod 5-3 between them, a base 5- 5 and top cladding 5-7. After the peripheral circuit inputs a rectangular wave or square wave signal with extremely low frequency to it, the coil 5-2 generates a pulsed magnetic field under the action of this current, and the polarity of the magnetic field at a certain moment is as follows: Figure 5 marked. The permanent magnet 5-4 and the permanent magnet 5-6 move to the right under the action of this magnetic field to impact the coating 5-7. When the current is zero or reversed, the permanent ma...

Abstract

The invention discloses a physiotherapy chair based on a pulsed magnet field. The physiotherapy chair is composed of a neck coil 1, waist and back coils 2, a cushion coil 3, knee coils 4, a peripheral circuit 5 and a chair 6. Each coil can contain the structures including an outer-layer coil, a spring, a permanent magnet and a coating layer. After recurrent pulse current with adjustable pulse width, frequency and amplitude is introduced into each oil, the permanent magnet can perform reciprocating motion under the action of the magnetic force and the elastic force; with the structure, the physiotherapy chair can carry out pulse magnetotherapy or vibration massage on a user independently, and also can carry out both the pulse magnetotherapy and vibration massage on the user according to the demands.

Description

technical field [0001] The invention belongs to the field of physiotherapy equipment or home furnishing, in particular to a physiotherapy chair based on a pulsed magnetic field. Background technique [0002] In 1974, American scientist Bassett discovered for the first time that when patients with nonunion were stimulated with pulsed electromagnetic fields (PEMF) every day, their fracture healing rate was significantly improved; in addition, he believed that the weak induced current generated by PEMF in the bone is the reason for its bone-promoting effect. The main mechanism of generation. The safety of PEMF has also been approved by the US FDA, and it began to be used clinically in the late 1970s. Based on Bassett's research results, scholars have conducted research on the osteogenesis-promoting effect and mechanism of PEMF from different perspectives. In vitro experiments show that PEMF can significantly accelerate the proliferation, differentiation and mineralization of ...
