Abstract

The utility model relates to an improved medical appliance, belonging to a TDP radiation treatment apparatus which is composed of a radiator (1) and a parabolic reflecting mirror (2), wherein, the radiator (1) is positioned at a focal point; as a result, radiation efficiency (comprising electromagnetic waves and 'particles') is enhanced. A frame-shaped base (4) is attached to a human body through a lacing (3) so that the problem of a support structure is conveniently solved. The relative positions of the reflecting mirror (2) and the radiator (1) can be adjusted so that radiation intensity is adjusted. Under the condition of unchanged work characteristics and medical characteristics, the cost of a TDP radiation treatment apparatus can be reduced to around 20 yuan, and power expenditure is tens of watts.

Description

Radiation treatment apparatus

This utility model relates to a kind of improved medical apparatus and instruments---TDP radiation treating unit or TDP class radiation treating unit.Here the TDP class of saying, promptly radiant body coating composition and operating temperature are all basic identical with TDP.

The operating temperature of TDP radiation treating unit radiant body is up to hundreds of degree.The radiant body that equivalent area is arranged can not the irradiation at short distance human body under high like this temperature, and general distance is about 30cm.The irradiance of TDP irradiator is roughly pressed square doubly decay of distance.So effective radiation that human body bears seldom.Like this, power consumption is big on the one hand, and capacity usage ratio is very low; The support that needs a heaviness, costliness on the other hand.

Above prior art CN85100830A and General Hospital, Shenyang Military Command's metal and stone just, Zhang Yanping work " to the research of some physical characteristic of TDP " (carrying " a collection of selected materials of specific electromagnetic wave Conference Papers " 7～12 pages), and reflection is arranged all in the operation instructions of each TDP producer.

This utility model has structurally been made significant improvement, has reduced the energy consumption of TDP radiation treating unit significantly, has cancelled supporting structure.

This utility model gets the dimensional contraction of TDP radiant body very little, makes on its focus that places a parabolic mirror, makes electromagnetic wave become parallel beam to external radiation.The parabolic lens opening is buckled on the position that needs irradiation, and therapeutic apparatus is tied up on body with frenulum.Radiant body itself can keep higher temperature so on the one hand, has guaranteed the radiance of TDP coating; Reflection by parabolic lens on the other hand, emittance can be more evenly, mildly according to human body, distance can every very near, and reflecting mirror is mapped to the radiation orientation direction again, it is very little to dissipate.Because the distance of radiant body and human body shortens greatly, " microgranule " radiation effects is also strengthened greatly, has guaranteed this therapeutical effect on the one hand.

Below in conjunction with accompanying drawing, further introduce its structure.Fig. 1 is main cutaway view, and Fig. 2 is right cutaway view, and Fig. 3 is a upward view.Tubule shape radiant body (1) in this legend by the electric heating porcelain core, puts the sheet steel pipe that scribbles the TDP coating outside, or coating directly is coated in the porcelain core outer surface and constitutes.Radiant body (1) is fixed on above the shaped as frame base (3) of hollow by support (2).Perpendicular above the base (3) have four metallic rod (4), and there is spacing preiection on metallic rod (4) top.Metallic rod (4) is inserted on shell (5) inwall in fixed four spring leafs (6).Shell (5) can move up and down along metallic rod (4) under external force, with the relative distance of adjusting with base (3), and don't can throw off with base.A parabolic mirror (7) is installed in the shell (5).Be tiltedly installed with two reflecting mirrors (8) in addition at two of parabolic lens (7).Base (3) is equipped with two frenulums that can be buckled together each other (9) on the lateral symmetry position, and other has the spare tape can be with frenulum (9) spreading, to satisfy the needs of different parts.Base (3) can be tied up on the position that human body need shine together with whole therapeutic apparatus with frenulum (9).When shell (5) when sliding into extreme lower position, promptly during it and base (3) nearest, support (2) guarantees that radiant body (1) is positioned at the focal position of parabolic lens (7).This moment body to be subjected to radiation the strongest, shell (5) is upwards slided, then radiant body (1) leaves the focal position of parabolic lens (7), the radiation falloff that body is subjected to.Regulate radiant intensity thus.Suitably perforate (10) is with heat radiation on shell (5) sidewall.

The utility model can be reduced to tens of watts of levels with the power consumption of general TDP therapeutic equipment from about three hectowatts, cost drops to tens of units, preheating shortened to one, two minute by surplus ten minutes, case temperature is also near human body, use very convenient, safety, fasten after the therapeutic equipment, human body still can move freely, and can add a cover clothing, tegmentum, help patient's warming and health hidden.

Adopt the electric heating porcelain core about 20W, the TDP material directly is coated in the porcelain core surface, can realize best technology---economic effect, every cost is only about 20 yuan.
