我们试制的眼科电热敷器由电源及换能器两部分组成,电原理图见附图。其中工作电压由220伏市电降为20-30伏,连续可调,热敷温度为40-55℃,该机可同时供2-4人热敷。使用时,需备好敷料,用纱布叠成换能器大小,用水浸湿。接通电源,绿灯亮后五分钟,调节温度旋钮到所需温度。病员取立、坐,卧姿均可。把带有纱布的换能器固定在眼上,即可热敷。它与热水袋相比有如下优点: (1)能保持一定温度,有利于治疗。 (2)操作简便易行,病人可以自行热敷,从而减轻医护人员的工作量。
Our trial of ophthalmic electric device by the power supply and the transducer composed of two parts, the electrical schematic see the accompanying drawings. One of the working voltage from 220 V mains to 20-30 V, adjustable continuously, hot temperature is 40-55 ℃, the machine can be used for 2-4 people at the same time hot compress. Use, need to be prepared dressing, stacked with gauze transducer size, soaked in water. Turn on the power, the green light after five minutes, adjust the temperature knob to the desired temperature. Patient taken stand, sit, lying position can be. The gauze with the transducer fixed in the eye, you can heat. It has the following advantages compared with the hot water bottle: (1) to maintain a certain temperature, is conducive to treatment. (2) easy to operate, patients can self-heat, thereby reducing the workload of medical staff.
