Osteoblast healing apparatus using pulsed electromagnetic fields

摘要

The present invention relates to an osteoblast growth promoter, and more specifically, to generate a pulsed electromagnetic field having a frequency of 10 ~ 20Hz to enable variable pulse control of osteoblasts and chondrocytes and to control the fracture intensity by controlling the intensity of the electromagnetic field The present invention relates to an osteoblast growth promoter using a pulsed electromagnetic field that can assist in the treatment effect or treatment of femoral head aplastic necrosis.;The purpose of the present invention is to provide a variable pulse at a predetermined frequency, which is used to treat fractures of the joints that have failed to fuse for at least 9 months after the wound with the unbonded bone and the fracture has not been shown to be effective for at least 3 months. Controllable, adjustable magnetic field strength, including flexible, rigid treatment coils that can be tailored to the location of the fracture, the vertical length of the fracture, the depth of penetration required for the fracture, and the size of the patient's limbs. To provide an osteoblast growth accelerator using the pulsed electromagnetic field.;The configuration of the present invention for achieving the above object, the display unit 10 consisting of a predetermined LED segment so that the user can see the frequency and magnetic field strength and operating time of the current output, and the strength and operation of the frequency and magnetic field The strength of the magnetic field by the control unit 20 which can adjust the time, the frequency converter 40 which sets the output frequency by the frequency setting signal of the control unit 20, and the magnetic field strength setting signal of the control unit 20 Magnetic intensity control unit 50 to adjust the, and receives the signal of the operation unit 20 and outputs to the display unit 10 and outputs a control signal to the frequency converter 40 and the magnetic force control unit 50 Magnetic field output unit 70 for outputting a signal for generating a suitable magnetic field by the control signal of the control unit 30, the frequency converter 40 and the magnetic strength control unit 50, and the magnetic field output unit 70 By output signal of It is characterized by consisting of a coil 80 for generating a magnetic field, and a power supply unit 60 for supplying power to operate the respective parts.;Also preferably, the power supply unit may include a first constant power generation unit 61 for receiving normal commercial power and converting it through a transformer T1 so as to correspond to a predetermined operating power supply Vcc and V _DD , and a transformer T2. And a second constant power generator for converting the power supply unit, wherein the power supply unit includes a charger circuit for charging a predetermined power through a transformer T3 and a commercial power supply, and a power supply by charging through the charger circuit. It is characterized by consisting of a portable battery 63 for supplying (Vcc) and a DC / DC converter 64 for supplying a power supply (V _DD ) having a predetermined voltage and current.
