Abstract

An LED cold light source for a medical endoscope mainly adopts the scheme that an electrical controller is arranged in a housing and is connected with a radiating fin through an LED luminous source, and the radiating fin is connected with a light cone sleeve through the LED luminous source connected therewith via a lens assembly; a light cone threaded connector is formed at one end where the lightcone sleeve extends out of the housing, and is connected with a guide light cone connector of the endoscope; and the LED luminous source emits white cold light with adjustable brightness under the action of an LED driving device to provide cold light source for lighting for the endoscope. The LED cold light source has the advantages of small volume, low energy consumption and lighting heat quantity, moisture and shock resistance and simple and convenient operation. Because the three power supply systems of AC power supply, built-in battery supply and external storage battery supply are adopted in the LED cold light source, the cold light source can be provided for the endoscope continuously so as to guarantee the continuous operation of the endoscope.

Description

Medical endoscope LED cold light source

Technical field

This utility model relates to a kind of medical apparatus and instruments, medical endoscope LED cold light source particularly, and it can be used as observes the lighting source that carries out medical diagnosis and operation to peeping in the human body.

Background technology

Usually, traditional endoscope utilizes the cold light source generator to import light into endoscope by light guide bundles, as the illumination for endoscope light source, is used to observe the situation of inside of human body.At present, the cold light source of employing is halogen tungsten lamp, xenon lamp mostly, and it is luminous based on bulb, and its light-source brightness is strong, but the heat that is produced is also higher, can cause unnecessary wound to the patient like this.And the volume of this cold light source generator is big, and is heavier, and use inconvenient, operate loaded down with trivial details, the power consumption height.Simultaneously, the service life of luminous source bulb is short, also needs the stable alternating current power supply of 220V.Suddenly taking place under the situation about having a power failure, can't operate as normal, also make troubles not only for the medical worker to the patient.

Summary of the invention

The purpose of this utility model is to provide a kind of medical endoscope LED cold light source, it can overcome the deficiency of prior art, can reduce the heat that luminous source produces effectively, it is low to consume energy, and luminosity scalable, application is strong, and can guarantee still can work in power failure or under away from the situation of power supply.

Its solution is: be provided with electric controller in housing, it is connected with fin by the LED luminous source, fin is connected with the lens assembly by the LED luminous source again, the lens assembly is connected with the light cone sleeve, and the light cone sleeve stretches out and on the outer end of housing screw thread is arranged, this end is the light cone hickey, and it is connected with endoscope leaded light tapered joint mouth.

Described electric controller is by the regulated power supply that connects the 220V alternating current power supply; this regulated power supply is electrically connected with automatic charge protection device and LED driving device respectively; automatically charge protection device is electrically connected with built-in rechargeable battery again; also be electrically connected with the LED driving device, and the LED driving device is electrically connected with external accumulator, brightness regulating switch and LED luminous source respectively and constitutes by the internal battery power switch.When the LED driving device obtains electricity work, under the effect of LED driving device, the LED luminous source sends cool white light, this cool white light scioptics assembly optically focused becomes rectilinear light beam, go into endoscope through light cone hickey and endoscope's leaded light tapered joint oral instructions, the cold light source that is provided for throwing light on for endoscope.

This utility model adopts technique scheme, it has, and volume is little, in light weight, power consumption is low, heat that luminous source produces is low and luminosity can be regulated, application strong, and can protection against the tide, antidetonation, characteristics easy and simple to handle.Because it adopts 220V alternating current power supply, internal battery power supply and external battery feed three tunnel electric power systems, can guarantee for endoscope provides cold light source continuously, to guarantee the persistence work of endoscope.Maybe can't utilize under the situation of 220V alternating current power supply having a power failure, if the time more in short-term, can utilize built-in rechargeable battery as power supply, if the time than long time, can external external accumulator as power supply.Thereby can provide cold light source for endoscope's persistence.

The specific embodiment

Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.

Among Fig. 1, Fig. 2, be connected with fin 9 at housing 1 internal fixation, connected LED luminous source 8 is arranged in the left side of fin 9, its scioptics assembly 7 is connected with light cone sleeve 6, on the end outside light cone sleeve 6 stretches out housing 1 screw thread is arranged, this end is a light cone hickey 5, and the end that light cone sleeve 6 stretches out housing 1 is fixedlyed connected with housing 1 through hold-down screw 3 by fixed disk 4 again.And in the housing 1 on fin 9 right sides, be provided with electric controller; by the 15V regulated power supply 10 that is connected with housing 1 internal fixation; this regulated power supply 10 connects the 220V alternating current power supply by 220V on and off switch 12 and the 220V supply socket 11 that is electrically connected and is fixedly connected on it on housing 1 side; 15V regulated power supply 10 is electrically connected with LED driving device 14 and automatic charge protection device 16 respectively again; and charge protection device 16 is electrically connected with built-in charged lithium cells 17 automatically; automatically charge protection device 16 also is electrically connected with LED driving device 14 by the internal battery power switch 13 that is electrically connected and is arranged on it on housing 1 side; LED driving device 14 again respectively be fixed on housing 1 side on brightness regulating switch 2 and external accumulator interface 15 be electrically connected with external accumulator 18, be electrically connected with LED luminous source 8 again simultaneously and constitute.

During use; at first light cone hickey 5 is connected with endoscope leaded light tapered joint mouth; connect 220V again and exchange battery; open 220V on and off switch 12; the 220V alternating current is exported needed regulated power supply after 10 voltage stabilizings of 15V regulated power supply; make LED driving device 14 obtain electricity work, give built-in charged lithium cells 17 chargings through charge protection device 16 automatically simultaneously, stop automatically after charging is finished and discharge prevention.LED luminous source 8 sends cool white light under the effect of LED driving device 14, can regulate the brightness of cool white light by brightness regulating switch 2 as required.And sending cool white light scioptics assembly 7, LED luminous source 8 becomes rectilinear light beam, and inject endoscope through light cone hickey 5 and endoscope's leaded light tapered joint mouth, as the endoscope illumination cold light source, so that peep the intravital pathological changes situation of patient of looking into, for medical diagnosis and treatment provide foundation.
