Abstract
The utility model relates to a temperature controller for a medical instrument with a heat source. The utility model is composed of a radiator, wherein the radiator is connected with an installing frame of a light source of a medical instrument. A main circuit used for controlling the light source is arranged in the medical instrument. A position at the bottom of the radiator approaching to the installing frame of the light source is provided with a temperature controlling relay connected in series with the main circuit through a conducting wire. When ventilating conditions of the medical instrument are changed to be poor, and the internal temperature rises to reach the control temperature of the temperature controlling relay, the relay is disconnected, electricity is interrupted and the instrument stops working. People can turn off a power switch, and after the temperature of the instrument descends, the instrument is turned on again. The utility model is provided with the temperature controlling relay on the radiator of the light source of the medical instrument, when the temperature in the instrument reaches a definite temperature limit, the instrument can automatically stop, which solves the problem that the hidden trouble on safety exists when the instrument is used for a long time and heat radiation conditions are changed to be poor.
Description
Technical field:
The utility model relates to measuring instrument, relates in particular to medical diagnostic equipment, particularly a kind of temperature control equipment that is used to the medical apparatus of thermal source.
Background technology:
Primary fluorescence early cancer diagnosis equipment of the prior art utilizes the optical excitation human body mucous membrane tissue of specific wavelength, under the excitation light irradiation of sufficient intensity, normal tissues, abnormal structure can produce the autofluorescence of different colours, and this exciting light is to be sent by specific light source, when this light source igniting, must produce a large amount of heats, and when the radiating condition of instrument become abominable the time, the hidden danger of secure context will take place in instrument.Primary fluorescence early cancer diagnosis equipment of the prior art or optical biopsy short cavity road diagnosing tumor instrument all do not have the light-source temperature control system, in case when instrument uses for a long time, radiator fan damages, the heat of instrument internal can't be discharged, when temperature surpasses the bearing temperature of plastic casing, power line plastics exoperidium, the exoperidium of power line will soften, plastic casing will be out of shape, and machine can't normally use, and operation doctor and patient works the mischief.
Summary of the invention:
Technical problem of the prior art to be solved in the utility model is: because primary fluorescence early cancer diagnosis equipment of the prior art or optical biopsy short cavity road diagnosing tumor instrument all do not have the light-source temperature control system, in case when instrument uses for a long time, radiator fan damages, the heat of instrument internal can't be discharged, when temperature surpasses the bearing temperature of plastic casing, power line plastics exoperidium, the exoperidium of power line will soften, plastic casing will be out of shape, machine can't normally use, and operation doctor and patient works the mischief.
The utility model is that the technical scheme that solution above-mentioned technical problem of the prior art is adopted provides a kind of temperature control equipment that is used to the medical apparatus of thermal source, described this being used to is made of a radiator with the temperature control equipment of the medical apparatus of thermal source, described radiator is connected with the light source installing rack of medical apparatus, be provided with the main circuit of control light source in the described medical apparatus, wherein, the bottom of described radiator is provided with a thermostat relay near the position of light source installing rack, and described thermostat relay is connected in the described main circuit by lead.
Further, described radiator is a metal heat sink, and described radiator is provided with radiator fan.
The course of work of the present utility model is: when medical apparatus ventilation condition variation, internal temperature rises, and when reaching the control temperature of thermostat relay, relay disconnects, power failure, and instrument quits work; Can close mains switch this moment, starts shooting after waiting machine temperature to lower again.
The utility model and prior art contrast, and its effect is actively with tangible.The utility model is provided with thermostat relay on the light source heat radiation device of medical apparatus, instrument can autostop when instrument internal reached certain temperature extremes, the security hidden trouble when radiating condition becomes bad in having solved that instrument is long-time and using.
Description of drawings:
Fig. 1 is the structural representation that is used to the temperature control equipment of the medical apparatus of thermal source of the present utility model.
Embodiment:
As shown in Figure 1, the temperature control equipment that is used to the medical apparatus of thermal source of the present utility model, constitute by a radiator 1, described radiator 1 is connected with the light source installing rack 2 of medical apparatus, be provided with the main circuit 3 of control light source in the described medical apparatus, wherein, the bottom of described radiator 1 is provided with a thermostat relay 4 near the position of light source installing rack 2, and described thermostat relay 4 is connected in the described main circuit 3 by lead.
Further, described radiator 1 is a metal heat sink, and described radiator is provided with radiator fan.
