Description
The present invention relates to a kind of medical treatment device, particularly a kind of electromagnetic inductive therapeutic device.
Disclosed magnetotherapy apparatus, most of permanent magnet that adopts, its pole orientation and magnetic field intensity are constant, and what have also is provided with heater or reuse medicament plaster; Other has a kind of as Chinese patent 89214828.4 rotating excitation field magnetotherapy apparatuies, is with the rotation of motor drives permanent magnet, or connects the coil of ribbon core with alternating current, produces the utmost point to alternating magnetic fields; Chinese patent 89201090.8 electric adjustable magnetotherapy apparatuies are still arranged, and also are to adopt the ferromagnet that is wound with coil as magnetic pole, in order to produce alternating magnetic field.
Above-mentioned two class magnetotherapy apparatuies can play the mitigation of unfolding to slight illness within a certain period of time, but common drawback is all to need to make magnetic core with ferromagnetic material, magnetic field is only by the pole-face radiation, even use the electric magnet of alternating current, magnetic energy by the electric energy conversion concentrates on the little pole-face equally, and magnetic field intensity is subjected to the magnetic core restriction saturated easily, in addition so little pole-face can not the bigger grieved position of area coverage, so treatment cycle is long, especially the constant permanent-magnetic field of pole orientation and magnetic field intensity, the life-time service people knows from experience and produces the anti-adaptability for the treatment of, curative effect continued in time and descend, in a word its treat speed and curative effect undesirable.
Task of the present invention is the above-mentioned shortcoming that overcomes existing magnetotherapy apparatus, provide that a kind of magnetic field of not having a magnetic core is adjustable, swept area is enough big, magnetic field intensity scalable, magnetic line of force length of penetration can be selected, magnetic energy acts on affected part and can convert bioelectric current and heat to, thereby the electromagnetic inductive therapeutic device that quickens the affected tissue rehabilitation.
Finishing task of the present invention realizes by the following technical solutions.
Therapeutic apparatus of the present invention is by the magnetic energy device (1) of recruiting, magnetic field generator (2) and connect lead and assemble, and medical institutions use can add position regulating device and limbs supporting arrangement, to satisfy clinical use needs.
Magnetic field generator (2) turns to excircle eccentricity induction coil (GL) with the electromagnetic wire of surface insulation, also can turn to parallel laminated induction coil, its inner cavity size and people's extremity, each position loose fit (appearance is protected with insulant) of body, can move freely, so that it is in place or withdraw to be sleeved on the limbs affected part, its specification size forms series, and what medical institutions used can add temperature-sensitive element, connects with the recruit thermindicator of device (1) of magnetic energy.Eccentric induction coil is that a kind of number of turn is identical with the line footpath, but line bag thickness and width are in two relative radius, from the thickest, be too narrow to special coil (seeing Fig. 3,4) the thinnest, the wideest transition gradually most, experimental results show that, after the energising, magnetic field intensity is along with the increase of the attenuate of line bag thickness and width and from successively decreasing to weak by force, thereby revolving coil can regulate the size of magnetic field intensity, makes it to obtain optimum efficiency corresponding to affected part.
Magnetic energy is recruited in the circuit of device (1), the time relay (SJ), voltage regulator (UT), the transformator (UB) of timing cutting power are housed, and can in circuit, insert pulse generation amplifier (MF) again, select with permutator (HK), make the output electric energy produce alternating magnetic field or pulsed magnetic field respectively at magnetic field generator (2) inner chamber, to be fit to needs and the anti-adaptability for the treatment of of deduction and exemption human body to affected part treatment, medical institutions use can add the output intensity indicator, thermindicator is used during with convenient clinical supervision and levelling parameter.
Magnetic energy recruit device (1) voltage regulator (UT) and transformator (UB) connected two kinds: first transformer secondary output is provided with a plurality of taps, and many grades of tap switches of voltage regulator adapted (FK) are connected successively with each tap of transformer secondary output; It two is that voltage regulator is the autocoupling type induction voltage regulator, or the SCR AC pressure regulator, and its outfan is connected with the elementary of transformator, does not secondaryly establish tap, realizes stepless voltage regulation.The induction coil (GL) of magnetic field generator (2) is the hollow coil that inner chamber does not have ferrimagnet, is electromagnetic wire (2a) to be looped around on the insulating hollow skeleton (2b) make; Also can turn to exoskeletal tread flaking formula, coil is drawn through plug (JK) or lead end to end.
The recruit contour structures of device (1) of magnetic energy is made table and is put formula, also can combine with the position regulating device or the limbs supporting arrangement of magnetic field generator (2).
The invention will be further described below in conjunction with accompanying drawing.
