The Development Of A Therapeutic Equipment For Hypothermic Cancer Therapy

Thermal needle medical equipment is a late-model medical equipment developed on the basis of hyperthermic cancer therapy. The principle of operation,the structure of the equipment,the way of heating,the method of temprature control and temprature display are mainly introduced in this paper.Having compared with the heating principles of the existing hyperthermic cancer therapy,the method of resistance heating is a better heating scheme and be adopted as the heating principle of the thermal needle medical equipment.The control system of equipment that uses the MCS-51 single chip,89C51, as the CPU mainly processes the temperature control and display. The thermal needle medical equipment that is developed with this scheme has many advantages such as the accurate temprature control,the simple structure ,low-cost and the minimum bulk.The performance measurement of the equipment indicates that the temperature control of the eqipment is accurate and can be used in clinical test.
