Description

Multi-frequency micro-wave therapeutic instrument

What the present invention will provide is a kind of multi-frequency micro-wave therapeutic instrument, belongs to the Medical Instruments technical field.

The prior art such as the patent No. 87208231 and the patent No. 89205095.0, these two kinds of microwave therapy apparatuses all adopt magnetron.Its frequency 2450MHZ.That yet its defective is a power consumption is big, efficient is low, and penetration depth is shallow, has only about 1.5cm.

The purpose that the present invention proposes is the defective that overcomes above-mentioned existence, proposes a kind of multi-frequency micro-wave therapeutic instrument of being made up of solid-state circuit.

Technical solution of the present utility model: adopt existing power supply, power measurement display, temperature is surveyed the display in modern age in real time, intervalometer, add that feature of the present invention is made up of agitator 1,power amplifier 2, circulator 3, manipulator 4, controller 5, antenna 6, agitator 1 wherein has the f of two different frequencies₁, f₂Agitator,power amplifier 2 has the f of two different frequencies₁, f₂Power amplifier, circulator 3 has the f of two different frequencies₁, f₂Circulator, the f that antenna 6 has two different frequencies₁, f₂Antenna; Its annexation is the f in the agitator 1₁, f₂F in the outfan of agitator and thepower amplifier 2₁, f₂The input 8 of power amplifier joins, the f in thepower amplifier 2₁, f₂The outfan 9 of power amplifier and the f in the circulator 3₁, f₂The input 10 of circulator joins, the f in outfan in the circulator 3 and the antenna of direct contact type 6₁, f₂The input of antenna joins, the input 11 of controller 5 respectively with four outfans of intervalometer 12 and the outfan 3 of manipulator 4^#No. 1 foot of foot and temperature controller 13 joins.The structure of its antenna 6 is divided formula outside cavity type and the chamber, and the antenna pattern of cavity type is cylindric, the upper and lower flat that is shaped as of formula antenna outside the chamber.

Accompanying drawing is circuit theory diagrams provided by the invention.

Among the figure 2,4,5,13,12 all is integrated packages.They are respectively power amplifier, manipulator, controller, temperature controller, intervalometer.

Intervalometer is to preset treatment time, rupturing duty output automatically, and send sound equipment; Manipulator is to produce pulse-modulated signal, selects for treatment; Agitator is to produce microwave signal, f₁=433MHZ, f₂=915MHZ selects when needing for treatment; Transmitter is power amplification, launched microwave signal; Active antenna is a launching electromagnetic wave; The real-time observing and controlling of temperature shows it is to set the treatment temperature, and real time temperature is measured control and shown; Power measurement shows it is to show the transmitting power size; Power supply is to supply with the various power supplys of complete machine; Controller is the duty of control complete machine.

The characteristics of this therapeutic equipment: ⑴ selects the medical frequency of international microwave L-band. This instrument f₁Be 433MHZ, f₂Be 915MHZ, its penetration depth, the uniformity of heating is better than 2450MHZ etc. Because frequency is available, applicable to the treatment of the different lesions section application of different depth tissue. ⑵ the real-time automatic measuring and controlling for the treatment of temperature shows, has increased the treatment security, provides the objective quantitative foundation for exploring best therapeutic dose. ⑶ this therapeutic equipment emitter is the solid state power module, has international most advanced level. Compare with magnetron transmitter, this instrument has the reliability height, and the frequency stability height is low in energy consumption, efficient is high, leak little, long service life, the characteristics such as volume is little, and is in light weight. ⑷ antenna 6 inside can divide total radiation (0-360 °), 1/4 radiation (0-90 °) low in energy consumption, the efficient height, and penetration depth is big.
