Development Of WZ-Ⅰ Type Ultrasonic Therapeutic Apparatus

Ultrasonic therapy is to make ultrasonic sound's energy act on human bodies with pathological change,in this way to heal sickness and restore human to health. In recent years,technology of ultrasonic therapy steps into a new development days and makes innovative progress in some aspects along with the advancement of electronic technology. Multifold ultrasonic therapeutic techniques are put into use in clinic,such as common ultrasonic physical therapy,medicament permeated therapy,ultrasonic sound - electrotherapy and ultrasonic surgery,etc. These therapies' occurrence and progress make ultrasonic therapy hold an important position in medical therapeutic technology.The application field of ultrasonic therapy is very wide,so much as can be called " miscellaneousness". Almost human body's every part has record of being treated by ultrasonic sound. But according to clinic research and referrence to literature,ultrasonic therapy has the best curative effect on treating bone arthrosis and muscle ache. For other sickness,just trial researches were did,indeed clinic application has not been into action. We designed an ultrasonator which is aimed to treat bone arthrosis and muscle ache.In the course of ultrasonic therapy,dosage of ultrasonic sound is not only an important,but a complex problem. For once therapy,dosage includes of intensity and times. It's well-known that excessive much dosage ultrasonic sound could result in damage. But too small dosage couldn't operate. So ultrasonic therapeutic apparatus must have high stability output and security to sick. We adopt single chip micyoco(SCM) as control center as apparatus system. So that designed apparatus has the characteristic of safety. stability and easy to operate.The characteristic of my apparatus is here: 1. The original Ultrasonic signal adopts SCM's clock,This signal is stable and not easy to occur departure.2 use pulse width modulate(PWM) technology controls intensity of ultrasonic sound output. Regulation is convenient.3 There are six kinds of ultrasonic mode output,so as to provide several choice for treatment.4 It has function of giving an alarm once error is happened,which could avoid damage to instrument brought by error operation.The introduce of SCM makes the apparatus realize intelligence,which also make it feasible to use software to realize the function formerly completed by hardware. Consequently apparatus' design is simplified and stability is enhanced,but it can realize more functions.
