The sterilization of instruments in rural health clinics in less developed countries is an increasing problem as chemical methods can no longer be recommended and fuel wood is becoming increasingly scarce. It seems obvious, therefore, to utilize solar energy for sterilization purposes.
A solar oven was designed and manufactured using local materials and simple tools. It was tested by physical, chemical and microbiological methods and, after successful testing, installed in a rural clinic. The oven was able to generate temperatures above 180 degrees C. On days with direct sunlight the oven fulfilled the international recommendations for hot air sterilization. The chemical indicators, Browne's tubes type 3 and 5, also changed colour. It was difficult to reach the right value for the sterilization effect during months with a low sun position. A moveable oven, or two ovens, must be installed to solve this problem.
The solar oven has proven to be a realistic method for the sterilization of instruments.
The solar oven is easy to make and use. It saves fuel and can be used in most tropical areas.
在欠发达国家的农村卫生诊所，由于不再推荐使用化学方法且薪柴日益稀缺，器械消毒成为一个日益严重的问题。因此，利用太阳能进行消毒似乎是显而易见的。
使用当地材料和简单工具设计并制造了一个太阳能烤箱。通过物理、化学和微生物学方法对其进行了测试，在成功测试后，安装在了一家农村诊所。该烤箱能够产生高于180摄氏度的温度。在阳光直射的日子里，该烤箱达到了国际上对热风消毒的建议标准。化学指示剂，即3型和5型布朗管，也发生了颜色变化。在太阳位置较低的月份，很难达到消毒效果的正确数值。必须安装一个可移动的烤箱或两个烤箱来解决这个问题。
太阳能烤箱已被证明是一种切实可行的器械消毒方法。
太阳能烤箱易于制作和使用。它节省燃料，可在大多数热带地区使用。
