Medical digital adjustable time-delay exposure circuit

Abstract

The invention discloses a medical digital adjustable delay exposure circuit. The circuit comprises a power supply circuit, an exposure driving circuit and a timing exposure preparation driving circuit. Based on a digital chip with stable performance, a mature semiconductor transistor element and a standard unified resistor and capacitor, compared with a timing device with a mechanical structure, the circuit has a shockproof function. Compared with a scheme utilizing programmable components, the circuit scheme of a pure logic gate and a trigger has the advantages that: soft errors are avoided,and the performance is more stable. Through the design of a universal interface, the circuit can be adapted to mainstream radiation equipment on the market, such as a small X-ray machine, a bedside DRmachine, bone mineral density, an oral dental film machine, CBCT and the like, so that the circuit is high in universality and easy to popularize, and has important application value in actual clinical work.

Description

technical field [0001] The invention belongs to the field of medical electronics, in particular to a medical digital adjustable delay exposure circuit. Background technique [0002] As a medical imaging technologist, radiation exposure is more concentrated and frequent. Especially the bedside DR machine, bone density, oral dental film machine, CBCT, mobile small C-arm, etc. Large hospitals frequently use the above equipment, and in the process of use, they also face the problem of X-ray radiation. If the method of extending the equipment control line or the way of infrared remote control is used to solve the above two problems; although it can play a role in radiation protection to a certain extent, the following problems exist in the way of extending the equipment control line: increase Unnecessary psychological burden for patients; inconvenient use caused by too long cables and unhygienic dragging of wire bars on the ground, easy to cross-infect, leaving hidden troubles ...
