许多医院采用的KW65-3A高频电刀,其控制用脚踏开关与机内的220伏的高压继电器相连接。因为手术室必须时常冲刷消毒,难免溅水将脚踏开关弄湿,所以极易发生触电事故,很不安全。
The KW65-3A high-frequency electric knife used in many hospitals is controlled by a foot switch connected to a 220 volt high-voltage relay in the machine. Because the operating room must be scoured and sterilized from time to time, it is unavoidable to splash the water to wet the foot switch, so electric shock accidents are very easy and very unsafe.
