SAFETY DEVICE IN DEVICE FOR HEATING ANTISEPTIC SOLUTION FOR MEDICAL USE

摘要

PROBLEM TO BE SOLVED: To enhance safety by providing a valve for shielding the passage of liquid chemicals when more than the one being equal to over prescribed temp. passes in a device for heating an antiseptic solution for medical use consisting of a hose from a liquid chemicals tank for supplying the chemicals to be heated by means of a heater or the like and of a liquid chemicals phlem for discharging the chemicals or the like. ;SOLUTION: The liquid chemicals tank 1 of the device is provided with the heater 1a for heating the chemicals, a flow switch 1b for recognizing the amount of the chemicals and a temp. detector 1c for detecting temp. in the tank 1. When a pump 4 is operated, the liquid chemicals passing through the pump 4 enters a safety valve 8 through the hose 7, is discharged from the liquid chemicals phlem 10 by way of the hose 9 and a patient or the like is disinfected and washed. When it is detected that the temp. of the liquid chemicals is abnormally high since the chemicals in the tank 1 in abnormally high temp. flows into the safety valve 8 through the hose 7 owing to a fault in the temp. detector 1c or the like inside the tank 1, the valve 8 is operated and the passage of the liquid chemicals is shielded.;COPYRIGHT: (C)2000,JPO
