Abstract
Heat source overheat protector in a kind of medical apparatus; it is made up of a radiator; the light source mounting bracket of radiator and medical apparatus connects; the main circuit of control light source is provided with medical apparatus; radiator is provided with a bimetal strip thermostat close to the position of light source mounting bracket, and bimetal strip thermostat is by wired in series in described main circuit.When medical apparatus ventilation condition is deteriorated; internal temperature rises; when reaching the control temperature of bimetal strip thermostat; normally closed stationary contact and normally closed movable contact disconnect; main circuit power failure, instrument are stopped, while normally closed movable contact is connected with normally opened stationary contact; indicator lamp works, and prompts medical apparatus to be shut down because of overheat.The present invention solves security hidden trouble when radiating condition deteriorates in instrument long-time use.
Description
Technical field
The present invention relates to measuring instrument, more particularly to medical diagnostic equipment, thermal source overheats in particularly a kind of medical apparatus
Protection device.
Background technology
Primary fluorescence early cancer diagnosis equipment of the prior art utilizes the light exciting human mucous membrane tissue of specific wavelength,
Sufficient intensity is excited under light irradiation, and normal structure, abnormal structure can produce the autofluorescence of different colours, and the exciting light is
Sent by specific light source, substantial amounts of heat, and the evil of the radiating condition change when instrument must be produced when the light source igniting
When bad, the hidden danger of secure context will occur for instrument.Primary fluorescence early cancer diagnosis equipment or optical biopsy of the prior art are short
Cavity diagnostic meter for tumor does not all have light-source temperature control system, once when instrument uses for a long time, radiator fan damages, in instrument
The heat in portion can not discharge, when temperature exceedes the bearing temperature of plastic casing, power line plastics exoperidium, the exoperidium of power line
Will softening, plastic casing will deform, machine can not normal use, and to operation doctor and patient damage.
The content of the invention
It is hot in described this medical apparatus it is an object of the invention to provide heat source overheat protector in a kind of medical apparatus
Source overtemperature protection system will solve the out of contior technical problem of heat source temperature in medical apparatus in the prior art.
The present invention this medical apparatus in heat source overheat protector be made up of a radiator, described radiator with
The light source mounting bracket of medical apparatus is connected, and the main circuit of control light source is provided with described medical apparatus, wherein, described dissipates
The bottom of hot device is provided with a bimetal strip thermostat, described ground bimetal strip thermostat on the position of light source mounting bracket
By wired in series in described main circuit.
Further, a normally closed stationary contact, normally closed movable contact and one are provided with described bimetal strip thermostat
Normally opened stationary contact, by wired in series in described main circuit, described is normally opened for described normally closed stationary contact, normally closed movable contact
Stationary contact is connected by wire with an indicator lamp, and the other end of described indicator lamp passes through wire and power supply and bimetal leaf temperature
Control the normally closed movable contact connection of device.
Further, described radiator is metal heat sink, and radiator fan is provided with described radiator.
The present invention the course of work be：When medical apparatus ventilation condition is deteriorated, internal temperature rises, and reaches bimetal leaf temperature
When controlling the control temperature of device, normally closed stationary contact and normally closed movable contact disconnect, and main circuit power failure, instrument is stopped；Simultaneously
Normally closed movable contact is connected with normally opened stationary contact, indicator lamp work, prompts medical apparatus to be shut down because of overheat.
The present invention contrasts with prior art, and its effect is positive and obvious.The present invention dissipates in the light source of medical apparatus
Bimetal strip thermostat is provided with hot device, instrument energy autostop, is solved when instrument internal reaches certain temperature extremes
Security hidden trouble when radiating condition deteriorates in instrument long-time use.
