Description

Technical Field

[0001] The present invention relates to the technical field of X-ray machines, and in particular to a flat panel detector of a movable X-ray machine. Background Art

[0002] A mobile digital X-ray machine is a medical device that emits X-rays and can perform radiological examinations and radiotherapy on human tissue. Because it's portable, it's convenient to use. Medical staff can move the machine to a ward as needed, diagnosing or treating patients who are less mobile.

[0003] During diagnosis or treatment, the imaging site is typically placed between a flat-panel detector and an X-ray source. Chest radiography typically involves anteroposterior and lateral chest X-rays. This examination helps doctors visualize lesions in the lungs, pleural cavity, mediastinum, and heart. However, some patients with chest problems have difficulty standing, making standing chest radiography more cumbersome. Furthermore, performing radiography while lying on a bed can affect the results if the patient is unstable, and is not safe. Therefore, a mobile flat-panel detector for X-ray machines is needed.

Compressed air pushes the top column and the rack to move, thereby driving the transmission gear to drive the protective rod to flip.

[0010] In a possible technical solution, further, a restoring spring is sleeved on the guide rod for connecting the sliding block and the support plate, so that the guide rod is parallel to the detection plate in the absence of external force.

[0011] In a possible technical solution, further, the motor drive mechanism includes: a motor, fixedly mounted on the first mounting bracket; a second mounting bracket, rotatably mounted on the first mounting bracket; The support rod is installed on the second mounting bracket.

When the chest patient needs to lie flat on the bed for imaging, the height of the detection plate is adjusted by the lifting mechanism so that the detection plate can pass through the bottom of the bed, which can meet the patient's examination needs and select the appropriate imaging method according to the patient's physical condition. When a chest cavity patient needs to lie flat on the bed for imaging, the first protection bar deflects, driving the second protection bar to deflect similarly. The first and second protection bars then stand upright on both sides of the bed, thereby protecting the chest cavity patient and facilitating safe imaging. When the shift block is reset, the gas in the second sleeve enters the exhaust shell through the connecting pipe, and is then discharged through the air outlet on the wall of the exhaust shell, thereby blowing and cleaning the surface of the detection plate, removing impurities on the surface of the detection plate and improving the accuracy of the inspection.

[0034] The flat panel detector of the movable X-ray machine according to the embodiment of the present invention has the following beneficial effects: During use, when the patient stands for chest imaging, the motor drives the second mounting bracket to deflect, and the patient stands between the detection plate and the transmitter. When the chest patient needs to lie flat on the bed for imaging, the height of the detection plate is adjusted by the lifting mechanism so that the detection plate can pass through the bottom of the bed, which can meet the patient's examination needs and select the appropriate imaging method according to the patient's physical condition. When a thoracic patient needs to lie flat on the bed for imaging, the first protective bar deflects, and similarly drives the second protective bar to deflect.
