Traditional Chinese Electronic bladder stimulator: Circuit Design, Parts List & Workshop Prototype Guide
In short: Traditional Chinese Electronic bladder stimulator. 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 6606 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 bladder stimulatorDue to spinal strain, the patient lost his urinary function and had to keep a urinary catheter in his body to urinate. But this method often causes urinary tract infections and bladder stones. If the kidneys are involved, it can even endanger the patient's life. Electronic bladder stimulators are designed to solve the urinary function of patients with poor lower motor neurons. This stimulator consists of two parts: a transmitter and a receiver, and its block diagram is shown in Figure 72-1. The transmitter is placed outside the body, and it emits a pulse modulated signal with a carrier frequency of 1MHz. The receiver is a passive network, completely sealed with medical silicone rubber and permanently embedded in the human body. Its output wires and electrodes are connected to the bladder wall. When the transmitter is working, the low-frequency pulse output by the receiver stimulates the detrusor muscle on the bladder wall, causing it to contract, thereby achieving the purpose of excreting urine. After many animal experiments, it has been proven to have good results.An electronic bladder stimulator is actually a radio energy transmitter. Its transmitter requirements are: ① Have sufficient working distance ( …
