Electronic Anesthesia Device: Traditional Chinese Circuit Design Guide
In short: Traditional Chinese Electronic anesthesia. 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 2548 words of English technical text, translated and preserved without editing. It is intended for experimental and reference use, not for regulated or commercial certification.
Electronic anesthesia deviceThe electronic anesthesia circuit shown in Figure 73 can output 8 groups of electrodes at the same time. The 8 groups of simultaneous outputs do not affect each other. That is, adjusting any one group will not affect the other groups. The operating frequency can be selected arbitrarily within the range of 2Hz to 50Hz. Nowadays, the operating frequency is generally 2 to 3Hz. At this time, the 8 sets of outputs only consume 100mW. Only one person can operate it to replace the manual needle twisting work during the operation.Since the transistor oscillator is basically a constant current source, when there are more than two groups of outputs at the same time (such as four groups), if the output amplitude of one group is larger, the output of the negative pulse part of the other groups will be reduced accordingly. …
