Description
Technical Field
The present invention relates to an exposure hand brake operating device with a learning mode and an exposure hand brake operating method.
Background
The medical diagnosis X-ray device is a medical diagnosis instrument commonly used in hospitals, and the X-rays emitted by the medical diagnosis X-ray device can be used for performing perspective and photography on human tissues.
Currently, exposure handbrake for photographing in medical diagnostic X-ray equipment is mostly mechanical handbrake. The top of the exposure hand brake is provided with a first operation button and a second operation button, and the operation process comprises two stages. The first stage is: the first operating button is manually pressed until the first operating button is flush with the second operating button. The second stage is as follows: the first operation button and the second operation button are simultaneously pressed manually until the first operation button and the second operation button are flush with the top of the exposure hand brake. Wherein the time that the first operation button and the second operation button are flush with the top of the exposure hand brake is the exposure time of the medical diagnostic X-ray equipment.
The X-rays emitted by medical diagnostic X-ray equipment are harmful to operators. In order to protect an operator from irradiation, when a medical diagnostic X-ray apparatus is used in a hospital, the medical diagnostic X-ray apparatus and the operator operating the exposure hand brake are usually isolated, i.e., the medical diagnostic X-ray apparatus and the operator operating the exposure hand brake are respectively located in different rooms, and a partition wall is provided between the two rooms.
Medical diagnostic X-ray equipment is manufactured from manufacturers and needs to be subjected to electromagnetic compatibility detection before being put into the market. Such detection requires that the medical diagnostic X-ray apparatus be placed in an anechoic chamber. The anechoic chamber is a six-sided shielding space, at this time, the exposure hand brake of the medical diagnostic X-ray equipment can only be placed in the anechoic chamber, and the electric wires of the exposure hand brake extend to the outside of the anechoic chamber through the wall of the anechoic chamber, so that the arrangement of the medical diagnostic X-ray equipment can be changed, and the test result is affected, and therefore, an operator operating the exposure hand brake to detect the electromagnetic field can only be in the same room as the medical diagnostic X-rays.
In the process of performing electromagnetic compatibility detection on medical diagnostic X-ray equipment, the medical diagnostic X-ray equipment inevitably causes certain damage to operators.
At present, no device capable of automatically operating an exposure hand brake in an anechoic chamber to detect an electromagnetic field of medical diagnostic X-ray equipment exists.
