How to use our DR exposure hand switch? The difference between the first gear and the second gear of the DR exposure hand switch, why is it designed in two gears?
Before clarifying the difference between the first and second gears of the DR exposure hand brake switch, and why the design is divided into two gears, we must first understand the function of these two gears.
The first gear of the DR exposure hand switch is used to control the exposure preparation state, and the second gear is used to control the exposure.
As for why it is necessary to complete the exposure in two gears, let me give you a simple example below. If the first gear of the DR exposure hand switch completes the exposure directly, after the doctor takes the film, the DR exposure hand switch may be left unconsciously. If you accidentally touch the gear, it will cause exposure, and the exposure will definitely produce X-rays. If similar situations occur frequently, it will be harmful to doctors and patients. If the DR exposure hand brake switch has two Only one gear can complete the exposure, and the probability of triggering this exposure is reduced.
Second, the DR exposure hand switch is set to two gears to prompt and prepare. For example, before the film is taken, the doctor will tell the patient to set the position and start the exposure. At this time, the doctor can first press the DR exposure hand switch to be in the ready state. If the patient’s position is not suitable, he can adjust the position in time. , And then press the second gear again, which reduces the X-ray dose.
