Our hand switches are classified according to the gear position. There are currently three main types: one gear, two gears and third gear. Today I will mainly talk about the two-speed exposure hand switch. As the name suggests, two gears are two triggers. The first stage is the exposure preparation stage, and the second stage is the exposure state.
Do you know why you need to set two gears? Let me give you a simple example. If there is only one gear, the doctor may unconsciously put the exposure hand switch in his pocket after shooting. At this time, if you accidentally touch the button, it is easy to cause exposure, and exposure will inevitably produce X-rays. If used for a long time, it is harmful to the human body. If the exposure hand switch switch has two positions, the probability of triggering this exposure will be greatly reduced.
Then there is the setting of two gears, which serve as reminders and preparations: for example, when the doctor is taking a film, he will tell the patient how to position the patient. When the exposure begins, the doctor will ask the patient if he is ready to take the film. At this point, the doctor will press the first gear to make it in a ready state. If he finds that the patient’s posture is not appropriate, he will not press the second gear again, thus reducing the x-ray dose received by the patient.
Seeing this, I believe everyone has a clearer understanding of the design of the two-position exposure hand switch. Regarding the composition structure of the hand switch, from the appearance point of view, it is mainly divided into: handle, base, spring wire, and connector. The exposure hand switch is mainly divided into 3 cores and 4 cores. The length of the spring wire is 3 meters, 6 meters, and 10 meters. If there are special requirements, our company can accept customization.
