The electromagnetic physiotherapy instrument is characterized in that a housing of the electromagnetic physiotherapy comprises a control circuit which takes an LPC 9401 one-chip microcomputer as the core, a coil drive circuit, a control portion power supply circuit and a charged lithium battery, the housing further comprises an O-shaped coil support prepared by high-molecular elastomeric material, an inner concave surface of the coil support (1) is provided with an embedded groove (2), a coil (3) is fixed in the embedded groove (2), and an output cable used for providing power for the coil (3) is connected with a power supply output end of the coil drive circuit via a connecting end (4). The electromagnetic physiotherapy can directly act on a wounded part by generating 15Hz low frequency electromagnetic pulses having positive effects on blood flow at a fracture position and osteocyte regeneration, thereby having a positive effect on healing of the wounded part of the fracture patient.

Description

Promote union of fracture electromagnetic physiotherapy appearance

Technical field

This utility model relates to a kind of apparatus that is used for behind the fracture operation as auxiliary treatment, specifically, relates to a kind of device that utilizes the electromagnetic wave principle to carry out auxiliary treatment behind the fracture operation.

Background technology

Behind the fracture operation, the thrombosis that the modal recovery problem that the patient runs into is exactly a fracture is logical, causes the part congestion to occur, or even necrosis of subcutaneous tissue occurs.In the prior art, often adopt modes such as hot compress or diathermy to solve this type of problem, but owing to lack specific aim, often DeGrain.

Summary of the invention

In order to solve the prior art problem that provides in the background technology; This utility model provides a kind of promotion union of fracture electromagnetic physiotherapy appearance; This kind promotes union of fracture electromagnetic physiotherapy appearance, through producing promoting the pulse of the extremely resultful 15Hz low frequency electromagnetic of fracture blood flow and osteocyte regeneration, acts directly on the affected part; Therefore, very effective for the affected part healing that promotes fracture patient.

The technical scheme of this utility model is: this kind promotes union of fracture electromagnetic physiotherapy appearance; Comprise the physiotherapy table housing; In said physiotherapy table housing, comprising one is control core circuit, a coil driver, control section power supply circuits and a rechargeable type lithium battery with the LPC9401 single-chip microcomputer; The control signal input of said coil driver is connected to the control signal output ends of said control circuit, so that the 15Hz low frequency electromagnetic pulse signal that generates outputs to the power output end of said coil driver; The outfan of said control section power supply circuits is connected to the power input of said control circuit; Said rechargeable type lithium battery provides working power for said coil driver and control section power supply circuits simultaneously;

In addition; Said physiotherapy table housing comprise outward one by macromolecular material process " O " shape coil brace; Have embedded groove on the inner concave of said coil brace; Coil stationary is connected to the power output end of said coil driver after link is drawn for the output cable of coil power supply in embedded groove.

The utlity model has following beneficial effect: this kind physiotherapy table; Built-in chargeable lithium cell; During use, finish clamping plate or Gypsum Fibrosum etc. fixedly after the processing, coil brace is enclosed within the fixing back of fracture just can connects the physiotherapy table use at fractures such as the hands of fracture patient or lower limbs.The liquid crystal display screen of physiotherapy table shows accumulative total service time and remains treatment time that if electric weight is not enough, liquid crystal display screen has prompting, takes off physiotherapy table, uses special charger to charge and gets final product.In this instrument; Single-chip microcomputer and mu balanced circuit adopt low energy-consumption electronic device, and pulse generating mode and coil driver are reasonable in design, thereby make that the positive pulsewidth time of low frequency of 15Hz is longer; Load impedance is very low again, when guaranteeing therapeutic effect, can significantly reduce the product power consumption.Therefore, this kind promotes union of fracture electromagnetic physiotherapy appearance, can the pulse of 15Hz low frequency electromagnetic be acted directly on the affected part, and be very effective for the affected part healing that promotes fracture patient.

The specific embodiment:

Below in conjunction with accompanying drawing this utility model is described further:

Extremely shown in Figure 4 like Fig. 1; This kind promotes union of fracture electromagnetic physiotherapy appearance; Comprise the physiotherapy table housing; In said physiotherapy table housing, comprising one is control core circuit, a coil driver, control section power supply circuits and a rechargeable type lithium battery with the LPC9401 single-chip microcomputer; The control signal input of said coil driver is connected to the control signal output ends of said control circuit, so that the 15Hz low frequency electromagnetic pulse signal that generates outputs to the power output end of said coil driver; The outfan of said control section power supply circuits is connected to the power input of said control circuit; Said rechargeable type lithium battery provides working power for said coil driver and control section power supply circuits simultaneously.

Said physiotherapy table housing comprise outward one by macromolecular material process " O " shape coil brace 1; Have embedded groove 2 on the inner concave of said coil brace 1; Coil 3 is fixed in the embedded groove 2, after link 4 is drawn, is connected to the power output end of said coil driver for the output cable of coil 3 power supplies.

Power supply and control section circuit are as shown in Figure 3.Power circuit is supplied power to single-chip microcomputer and segment code type liquid crystal display screen after using low pressure differential voltage stabilizing chip that the lithium battery pressure drop is pressed onto 3V.Control section adopts the LPC9401 single-chip microcomputer; The LPC9401 single-chip microcomputer is actually the coalition of LPC931 single-chip microcomputer and PCF8576 segment encode lcd drive chip; Can directly be connected and do not need adjunct circuit, thereby reduce space hold effectively with the segment code type liquid crystal display screen.

This instrument optimal design focus on reducing power consumption, except that single-chip microcomputer and mu balanced circuit adopt the low energy-consumption electronic device, pulse generating mode and coil driver must adopt rational design.Fig. 4 is the circuit diagram of the said coil drive part of this utility model; Because 15Hz belongs to low frequency; The positive pulsewidth time is longer, and load impedance is very low again, directly uses 15Hz frequency drives switching tube and then drive coil will inevitably produce very large operating current; Thereby cause device heating and power consumption very high, therefore use the 100KHz impulse train to produce the positive pulsewidth part of 15Hz.The LPC9401 single-chip microcomputer is the 3.3V device, and the high level of output is 3.3V, uses the CD4069 not gate of 5V power supply to promote driving force here, and the square-wave signal level of single-chip microcomputer P2.2 foot output is risen to 5V.And then use audion to drive FET, make electric current flow through inductance coil, thereby produce the electromagnetic pulse of corresponding frequencies with correspondent frequency.In order to improve the utilization rate of electric energy; Connect a diode bridge rectifier circuit at the inductance coil two ends, when FET ended, the electric energy that stores in the inductance coil was through behind the diode rectification; Give the electric capacity that is connected in parallel on battery two ends charging; Electrical power storage is got up to supply next discharge cycle utilization, thereby reach the purpose that significantly reduces the product power consumption when guaranteeing therapeutic effect, good through the test proving effect.
