Objective To develop a simple film-developing heating device for army hospital below division. Methods An electric hand warmer was transformed and tests were made many times with different movement temperature of thermostat. Results The simple film-developing heating device could basically keep the photographic developer in constant temperature for best development effect in winter and spring. With simple structure and long service life, it is safe and convenient. Conclusion The simple film-developing heating device is desirable to be used in winter and spring and meets the practical requirements in the basic unit army hospital.

The abutting joint for XCY2002-1/200 field battle X-ray diagnosis vehicle and WCY2002-2/40 field battle operation vehicle are expounded. The methods and the process of their expansion are studied from regional reconnaissance,vehicle orientation,personnel or work distribution,operational order or skill and so on. The effect is good and quick,and the experience procedure is accumulated,which problems and corresponding improvement are put forward. The effectiveness is used for emergency operation of the serious wounded in frontier,and is expected to serve as reference for enhancing medical treatment efficiency and quality.

Objective To develop a simple new-type photographic device for the field battle and peace time,because of the function of the trivet of X-Ray machine is limited.Methods Circular chrome-plating seamless steel tubes,whose diameter is 4 cm and 5 cm respectively,were connected so as to constitute the arm structure in C shape and foundation in T shape.Results The simple new-type photographic device could project for patients in each kind of body posture and the range of focus adjustment could meet normal requirements.It was operated nimbly and freely.The material was durable and the structure was reasonable and stable.Conclusion The simple new-type photographic device meets the practical requirements in field battle and peace time.
