Abstract

A phototherapy unit, belonging to the field of radiotherapy equipment, is characterized by that a reflector is placed after halogen lamp, and betwen two plane-convex lenses placed in the optical circuit, before said lamp there is a red or green or blue colour filter which can be randomly changed, and an achromatic lens whose distance to lamp can be regulated for regulating faculous diameter is placed along the optical circuit in the front end of machine shell and a non-spherical lens capable of further reducing facula is placed for stand-by, and the halogen lamp is series-connected with voltage-regulator and timing device. Said invention can output approximate monochromatic light, its output light intensity, working time and faculous diameter in therapeutic zone are able to be regulated, so that it is applicable to clinicial therapy in hospital or health-protection in family.

Description

Phototherapy unit

The present invention relates to radiotherapy unit, particularly a kind of phototherapy unit.

Along with the development of laser medicine, after people knew the rayed human body, the biological effect of the complexity that the comprehensive function of light and heat produces helped to alleviate the pain and the inflammation of osteoarthrosis, human body, and the energy of suitably controlling illumination also can destroy some tumor tissues.And the laser structure complexity that is used for the treatment of is bulky, cost an arm and a leg, and is difficult to popularize.

Chinese patent CN 1053557A disclosed " optical curing device " is by iodine-tungsten lamp, two director sphere lens before the lamp rear reflector, lamp, and fiber optic cable and filter lens are formed.Adopt fiber optic cable conduction output white light lesions position.Be mainly used in and go deep into intravital irradiation, better to small size focus effect, and relatively poor to the therapeutic effect of large tracts of land focus.And the light loss consumption is bigger, and fiber optic cable costs an arm and a leg.

Chinese patent CN 1097148A disclosed " light combination therapeutic equipment " is by Halogen light, illuminator, formations such as taper lamp guide and optical filter.And can directly insert in the organs such as ear, nose, oral cavity, vagina, anus, form the high strength hot spot to carrying out light exposure treatment in the organ.Because the hot spot range of accommodation is limited, and is unsuitable for the larger area light exposure treatment.

Chinese patent CN 1093607A disclosed " spectral therapeutic instrumnt " is not owing to adopt illuminator and collecting lens, and the light utilization is very low, and must establish cooling fan, to ensure operate as normal; Spot diameter can be greatly but can not be turned down, and the buck diode of setting has been realized two grades of variations of strong and weak light.

" a kind of Halogen light Phototherapeutic instrument " that Chinese patent CN 225324Y describes mainly is made up of Halogen light and taper quartz pushrod, by improving lamp socket, makes the tungsten bar can be not overheated, with the accessible working time of prolongation instrument.

Purpose of the present invention is exactly for the spot diameter that a kind of approximate monochromatic light is provided, irradiation time, the phototherapy unit that is applicable to the irradiation of partes corporis humani position that intensity of illumination is adjustable, so the present invention has any different in prior art.

The present invention realizes by following technical scheme.

The alternating current Halogen light in the shell of meeting sb. at the airport, establish illuminator behind the lamp, the planoconvex lens of two identical relative arrangements in the light path before the lamp, casing front end edge parallel light path are provided with the achromat of regulating spot diameter with adjustable being used to of lamp distance, and the standby non-spherical lens that can further dwindle hot spot; Halogen light series voltage regulator and intervalometer in the circuit part.

Red or the green or cyan color filter that can arbitrarily change is folded in the middle of two planoconvex lenss.

Energized during use, the intervalometer control Halogen light working time of serial connection; Pressure regulator is adjusted output voltage, the control light energy output.The white light that Halogen light sends is through the reverse direction output of lamp rear reflector, through two relative planoconvex lenss the directional light of output is become and reach the light beam of energy by force, adjustable achromat before and after outfan adds, shine the spot diameter of lesions position in order to change, be suitable for surgery and various large-area irradiation.Also can be as required before achromat, add a non-spherical lens, can make spot diameter little, be applicable to that treatment oral cavity, pharyngeal, vagina, cervix uteri, anorectal, auditory meatus etc. locate focus to 5mm.The red, green, blue colour filter that inserts in the light path makes the proximate monochromatic light of output, can be suitable for HONGGUANG as the shallow pathological changes for the treatment of depth different parts pathological changes; Dark pathological changes is suitable for blue light; And between being suitable for green glow between the two.

The approximate monochromatic light of the phototherapy unit output that designs like this, light energy output is adjustable, and the working time is adjustable, and the area for treatment spot diameter is adjustable.Therefore this phototherapy unit can be applicable to the clinical treatment or the family health care of hospital.

Below in conjunction with drawings and Examples the present invention is further described.

Fig. 1 is a light channel structure sketch map of the present invention.

Fig. 2 is circuit theory diagrams of the present invention.

1 spherical reflector, 2 Halogen lights, 3.4 planoconvex lenss, 5 achromats, 6 colour filter, 7 non-spherical lenses, 8.9.10. fixed mirror support, 11 interchangeable mirror supports, 12 casing, 13 insulating lamp holders, 14 lens barrels, 15 urceolus, 16 pressure rings, 17 slide trepanning among Fig. 1.L is that Halogen light, T are that intervalometer, B are pressure regulator among Fig. 2.

But the tubular casing inner bottom of horizontal sets firmly the insulated receptacle of plug-in mounting Halogen light, fixed support installs the sphere reflecting lamp behind the lamp, before the lamp in the light path planoconvex lens of two identical relative arrangements be installed on separately the fixed support, the reverse parallel output of direction of the white light that Halogen light is sent is folded in red or the green or blue color colour filter of plug-in mounting on two intermediary interchangeable mirror supports of planoconvex lens.Casing front end edge light path has and slides trepanning, is the lens barrel of achromat for an end is installed in it, make its can before and after slide mobilely, by changing the lamp distance, realize that spot diameter 30mm-200mm is adjustable.The lens barrel front end is urceolus by pressure ring internal fixation non-spherical lens of suit as required also, can make hot spot be contracted to 5mm, is used for treating internal lesions.The scope that realizes the adjusting spot diameter is 5-200mm.

Being series at the preceding pressure regulator of Halogen light in the circuit is general 220V, 500W, and working range is at 10-220V, and intervalometer is 1-60 minute, and general working range is 1 minute to tens of minutes.

Model machine of the present invention is obtained satisfied design effect through clinic trial, and human body is not damaged.
