The specific embodiment
Be described in detail the specific embodiment of the present invention below in conjunction with accompanying drawing.
A kind of ultrahigh frequency tumor treatment equipment; Comprise ultra-high-frequency transmitter 15,reflection isolator 13,irradiator 9, therapeutic bed 4,monitor 11, screened room 1,computer management system 18; Irradiator 9, therapeutic bed 4,monitor 11 are arranged in the screened room 1; Ultra-high-frequency transmitter 15 is connected withreflection isolator 13 through radio-frequency cable 14, andreflection isolator 13 passes through radio-frequency cable 14 connections mutually withirradiator 9; Monitor 11 is positioned at therapeutic bed 4 tops, is connected withcomputer management system 18 throughmonitor cable 12, and computer management system also connects ultra-high-frequency transmitter throughdata cable 16.
Monitor 11 among Fig. 1,reflection isolator 13, radio-frequency cable 14 are for can purchase parts.The double-deck 8-10mm steel plate of screenedroom metal wall 2 usefulness therebetween 50mm solid wood is processed.
The making of irradiator is referring to Fig. 2 a and Fig. 2 b:irradiator base plate 20 is made by the thick rigid plastics of 3mm withirradiator loam cake 19, uses nonmetal connection between them, for example uses plastics screw or adhesive to connect.Radiation ring 24 lies against on theirradiator base plate 20, and the diameter of ring is 185mm, is that the thick copper pipe bending of 5mm forms by diameter.Outer conductor adapter 22 is spirally connected with the outer conductor of theradio frequency connector 21 ofirradiator base plate 20 opposite sides, andradio frequency connector 21 is a L27 type flange form connector.One end ofradiation ring 24 is fixed on theouter conductor adapter 22 withbrass screws 26, and the other end is welded toinner wire adapter 23 on the inner wire of radio frequency connector, andinner wire adapter 23 adopts one section thick copper conductor of 4mm.For preventing the internal and external conductor short circuit, near the inner wire junction ofradiation ring 24, put the bearing of processing withpolitef 25.
