Traditional Chinese GZ- Ⅱ Bone Hyperplasia Therapeutic Apparatus (Workshop Practice) — Circuit, Wiring & Debug Guide
In short: Traditional Chinese GZ- Ⅱ Bone Hyperplasia Therapeutic Apparatus (Workshop Practice) — Circuit, Wiring & Debug Guide. This entry documents a circuit & prototype taken from Chinese practical-technology literature, written for small-scale makers and home producers. The text below is the full English translation of the original Chinese workshop notes, covering materials and quantities, the step-by-step sequence, and the practical cautions recorded in the source. Roughly 2490 words of English technical text, translated and preserved without editing. It is intended for experimental and reference use, not for regulated or commercial certification.
GZ-Ⅱ bone hyperplasia treatment instrumentThe bone hyperplasia treatment instrument is equivalent to a constant current output power supply. Its treatment mechanism is to introduce compound Chinese medicine ions into the lesion through the two output electrodes of the constant current source, thereby enhancing the penetration of the Chinese medicine and relieving symptoms such as limb pain, numbness, and inconvenience in walking caused by hyperplasia. This article analyzes the representative GZ-II bone hyperplasia treatment device.How it works:As shown in Figure 60, the treatment instrument has dual outputs, that is, it can treat two patients at the same time (only one channel is shown in the figure).When timer PT1 is turned on, the 40V AC output is rectified and filtered by DL1, C1, C2 and R3 and then added to the constant current output circuit. The constant current output circuit is composed of the power regulating tube VT1, the reference voltage regulating tube VT2, resistors R7, R9, R11, R13 and the potentiometer RP1.By adjusting RP1, the maximum output current is 30mA. The patient can adjust the output current according to the actual bearing capacity in order to obtain satisfactory treatment results.After the AC 5V passes through the rectifier bridge DL3, it passes through the filter capacitors C5 and C6, the current limiting resistor R16 and the voltage regulator tube VD1 to generate +3V DC, which is supplied to the two alarm circuits. The alarm circuit is composed of transistor VT3, music chip IC1 and speaker BL1. After the scheduled work of the therapeutic instrument is completed, the IC1 trigger terminal obtains a positive pulse trigger signal, generates an alarm, and promptly informs medical personnel.Figure 60Device selection:The power adjustment tube is a DD01B medium power tube, and its beta value should be greater than 80; the beta value of the reference voltage regulator tube 3DA87B should also be greater than 80; the power values of resistors R3, R4, R7, R8 and R16 …
