Embodiment Construction

[0010] Such as figure 1 As shown, the heat source overheating protection device in the medical instrument of the present invention is composed of a radiator 1, the radiator 1 is connected to the light source mounting frame 2 of the medical instrument, and the main circuit for controlling the light source is arranged in the medical instrument. Wherein, a bimetal temperature controller 3 is arranged on the bottom of the radiator 1 close to the light source installation frame 2, and the bimetal temperature controller is connected in series with the main circuit through wires.

[0011] Further, the bimetal thermostat 3 is provided with a normally closed static contact, a normally closed movable contact and a normally open static contact, the normally closed static contact, the normally closed movable contact It is connected in series in the main circuit through wires, and the normally open static contact is connected with an indicator light through wires, and the other end of the ...

Abstract

A heat source overheat protector in medical instrument consists of one radiator which is connected with medical instrumental light source mounting rack, said medical instrument set with light source control main circuit, bimetallic strip temperature control unit set nearing the light source mounting rack and series connected in said main circuit through wire. When medical instrument draft condition becomes poor and the internal temperature rises reaching the controlled temperature of bimetallic strip temperature control unit, the normally closed stationary contact and normally closed moving contact disconnect to make main circuit power interruption and instrument stopping work, at the same time normally closed moving contact and normal open stationary contact switching-on, indicating light working, prompting the medical instrument being stopped because of superheating. The present invention solves safety problem in instrument long time working.

Description

Technical field: [0001] The invention relates to a measuring instrument, in particular to a medical diagnostic instrument, in particular to a heat source overheat protection device in a medical instrument. Background technique: [0002] The intrinsic fluorescence early cancer diagnostic instrument in the prior art uses light of a specific wavelength to excite the human mucosal tissue. Under the irradiation of the excitation light of sufficient intensity, the normal tissue and the abnormal tissue will produce autofluorescence of different colors, and the excitation light is produced by a specific When the light source is turned on, a large amount of heat must be generated, and when the heat dissipation conditions of the instrument become severe, the instrument will have hidden dangers in terms of safety. In the prior art, neither the inherent fluorescence early cancer diagnostic instrument nor the optical biopsy short lumen tumor diagnostic instrument has a light source tempe...
