CN2416857Y - Near infrared light source for mammary gland diagnose instrument - Google Patents

Abstract

The utility model relates to a medical mechanism device, particularly a near infrared light source device for a mammary gland diagnose instrument. The near infrared light source device for a mammary gland diagnose instrument comprises a case body, optical fiber, light outlet head held by a hand, a reflection bowl with an ellipse surface, a special lamp bulb, a lamp holder, a pressing ring and a composite filter sheet. The utility model has the great advantage that only near infrared light is sent out from the light outlet head. Thereby, the mammary gland diagnose instrument is really operated in a near infrared optics zone. The mammary gland diagnose instrument can be operated under a lighting source without utilizing a darm room. The near infrared light source device for a mammary gland diagnose instrument can be widely used for mammary gland detecting instruments.

Description

Near infrared light source apparatus in the mammary diagnosis instrument

This utility model relates to the Optical devices in a kind of electronic medical instruments, the near infrared light source apparatus in especially a kind of mammary diagnosis instrument that is applicable to diagnosis of breast diseases.

The existing diagnostic instruments that utilizes high light perspective mammary gland mostly comprises following four parts: light source, video camera, monitor and controller.These diagnostic apparatus technical maturities, model is more.But a bit very big deficiency is arranged, and promptly light source is a visible light source.Video camera also is the television camera to the visible light sensitivity, and the spectral energy of its utilization that relies on mainly is in the visible region rather than in the zone of infrared or near infrared light.On the contrary, for can scald in the elimination light source human body in, far infrared, all be added with heat-protecting glass in the light path, the result is near infrared ray also elimination in the lump, only remaining visible light.So existing mammary diagnosis instrument has added the mammary diagnosis instrument of " infrared " title comprising some, in fact only to the visible light sensitivity.Operator avoid the interference of indoor visible light to diagnostic apparatus, and all without exception need operate in the darkroom.Need squeeze breast repeatedly when doctor's (mostly being the male) diagnoses patient's (often being the women), both sides feel inconvenience deeply in the dark.Secondly, light source and radiator fan all are contained in the lightening tube of a thick heaviness (being commonly called as probe), use inconvenience, and because bad need being used alternatingly with two lightening tubes of dispelling the heat.

The purpose of this utility model provides the near infrared light source apparatus in a kind of mammary diagnosis instrument, it can make mammary diagnosis instrument really only be operated in the near infrared spectrum zone, centering, far infrared and visible light are all insensitive, the medical diagnosis personnel can manipulate under indoor bright light environments, and can allow image more clear.

In order to achieve the above object, this utility model at first designs an optical bench, and an ellipsoidal surface reflector is set in optical bench, on a focus of reflector a special bulb is set, and its outside is the special bulb lamp socket; Then design four trim rings, its two ends are anchored on the inwall of optical bench, four trim rings are to settle like this, preceding two are tightly blocked the reflector edge, make reflector only be fixed in the optical bench, in the middle of two trim rings in back a composite filter sheet is set, but all visible lights and the mid and far infrared light of this optical filter elimination except that purple light.Because most visible light and mid and far infrared light are by elimination, thereby the light that penetrates from go out optical fiber, exhausted most concentration of energy at wavelength 750nm between the 1000nm, also promptly near infrared region.Also have the following purple light of some wavelength 415nm to penetrate in addition, its intensity is directly proportional with near infrared light, and direction is identical with near infrared light, is used to refer to invisible near infrared light.Because this pilot light is near infrared light purple light farthest, so it is to the minimum that influences of near-infrared gamma camera in the visible spectrum.Four trim ring intermediate hollows are a vent between two trim rings of pro-and back two trim rings, also have a mini fan in the reflector side, make its quick distribute heat.The cabinet respective side is opened a hole, adorns a fibre-optical splice.The fibre-optical splice perforate, a middle logical optical fiber, optical fiber one end puts in fibre-optical splice, and places another focus of ellipsoid reflector, and the other end connects holds out shaven head.

Great advantage of the present utility model is: it can make special bulb send light only to launch near infrared light, thereby makes mammary diagnosis instrument really be operated in the near infrared spectrum district.

Figure of description 1 is this utility model structural representation, and accompanying drawing 2 is the side view of accompanying drawing 1.

Number in the figure (1) is an optical fiber, (2) be lamp socket, (3) are special bulb, and (4) are the ellipsoid reflector, (5) be trim ring, (6) be vent, (7) are the composite filter sheet, and (8) are fibre-optical splice, (9) for holding out shaven head, (10) be optical bench, (11) are mini fan, and (12) are cabinet.

The concrete making of this utility model is: threaded optical bench (10) in the middle of at first making with metal, make ellipsoid reflector (4) again, purchase special bulb (3) and lamp socket (2), special bulb (3) is arranged on ellipsoid reflector (4) one focuses, special bulb (3) is inserted on the lamp socket (2), make four trim rings (5), tightly block ellipsoid reflector (4) with two trim rings (5), two trim rings (5) are arranged on vent (6) front in addition, one composite filter sheet (7) is set in the middle of these two trim rings (5), then make fibre-optical splice (8) it is contained in the corresponding side of cabinet (12), porose in the middle of fibre-optical splice (8), optical fiber (1) is put in, make its end face just on another focus of ellipsoid reflector (4).Optical fiber (1) other end connects holds out shaven head (9), through debugging.

Claims (1)

1, the near infrared light source apparatus in a kind of mammary diagnosis instrument, it comprises optical fiber (1), lamp socket (2), special bulb (3), ellipsoid reflector (4), trim ring (5), composite filter sheet (7), fibre-optical splice (8), holds out shaven head (9), optical bench (10), mini fan (11) and cabinet (12), it is characterized in that:

A, special bulb (3) are arranged on ellipsoid reflector (4) one focuses, and an end of optical fiber (1) is arranged on another focus of ellipsoid reflector (4);

One composite filter sheet (7) is arranged between b, the trim ring (5).
