Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical devices, in particular to a multifunctional auxiliary device for medical image diagnosis. BACKGROUND

[0002] Medical image diagnosis is to make the internal structure and organs of the human body imaging by medical image diagnosis equipment, so as to understand the anatomical and physiological function state and pathological changes of the human body, and to diagnose and treat diseases. Common medical image equipment includes digital X-ray machine, computer tomography equipment and nuclear magnetic resonance imaging system.

[0003] The digital X-ray machine mainly consists of an X-ray generator, a flat panel detector, an image processing system, a control system and a display. When the digital X-ray machine is used, the emission amount of X-rays is first determined by the control system, then the X-rays are generated by the X-ray generator, the X-rays are captured by the flat panel detector after passing through the patient's body, the captured X-rays are converted into electrical signals by the flat panel detector, and the electrical signals are converted into visual images by the image processing system, and finally the images are displayed on the display for doctors to view and diagnose.

[0004] During the use of the digital X-ray machine, when an obese patient is diagnosed by X-rays, due to the uneven distribution of fat and the decrease of muscle mass, the density of the obese patient is higher, the absorption angle of X-rays is higher, and thus the X-rays captured by the flat panel detector after passing through the human body are less, resulting in a blurred imaging effect of the X-rays, which is not convenient for medical staff to diagnose the patient's condition. If the emission amount of X-rays is increased, it is easy to cause damage to the patient's body.

[0005] Therefore, the prior art proposes a medical image diagnosis device, which adopts a multi-color replacement structure to clearly present the shadows and white spots in the image, improve the diagnosis efficiency of medical staff, and enable patients to intuitively see the abnormalities in the image. At the same time, through the setting of the distance adjusting structure and the self-locking structure, the distance between the medical staff and the patient for viewing the image can be adjusted, but the problem of unclear imaging of obese patients in X-ray diagnosis and detection has not been solved.

[0006] Therefore, we propose a multifunctional auxiliary device for medical image diagnosis. SUMMARY

[0007] The purpose of the present application is to provide a multifunctional auxiliary device for medical image diagnosis to solve the problems raised in the background.

[0008] To achieve the above purpose, the present application provides the following technical scheme:

The digital X-ray machine includes a column, a drive unit, a cantilever, an X-ray generator, and a detection platform. A drive cavity is formed on the column, and the drive unit is installed within the drive cavity. The drive unit is connected to the cantilever, and the X-ray generator is connected to the cantilever.

During use, the patient lies supine on the detection platform. Medical staff adjust the position of the support column through the control system, aligning it with the patient's examination area. They then adjust the height of the cantilever via a drive device, thereby changing the height of the X-ray generator and activating it to emit X-rays for examination. A pressure plate is mounted on the examination platform, with pressure sensors at both ends. These pressure sensors adjust the height of the X-ray generator via the drive device. When the patient lies on the examination platform, the pressure exerts pressure on the pressure plate, which transmits this pressure to the pressure sensors. The pressure sensors then transmit electrical signals to the control system, controlling the descent height of the cantilever.

[0010] The adjustment assembly is located below the pressure plate, and the flat panel detector is linearly arrayed within the adjustment cavity. When the height of the X-ray generator changes, the driving device drives the flat panel detector to slide upward through the adjustment assembly.

The compression assembly is located within the adjustment cavity, and the compression plate is located below the flat panel detector. When the flat panel detector slides, the adjustment assembly drives the compression plate to move in a centered position through the compression assembly. This centered movement of the compression plate promotes the smoothness of the lifting of the flat panel detector by the adjustment assembly, thereby maintaining the stability of the flat panel detector and preventing it from shaking during ascent, which would result in uneven X-ray capture and affect the clarity of the image.

When the digital X-ray machine 1 is in use, the patient lies flat on the detection platform 15. Medical staff adjust the position of the column 11 through the control system so that the column 11 is in the same position as the patient's detection area. Then, the position and height of the cantilever 13 are adjusted through the drive device 12, thereby changing the height of the X-ray generator 14. The X-ray generator 14 is then activated to emit X-rays to examine the patient.

[0043] The motor 121 is fixedly installed at the bottom end of the driving cavity 111, and the motor 121 is fixedly connected with the rotating shaft 122; the rotating shaft 122 is provided with a thread, and the rotating shaft 122 is slidably installed with the shaft sleeve 123; the shaft sleeve 123 is provided with a screw groove matched with the rotating shaft 122, and the shaft sleeve 123 is fixedly installed with the cantilever 13; the pressure sensor 2 transmits an electric signal to the control system according to the weight of the patient, the control system determines the height of the X-ray generator 14, and then transmits a signal to the motor 121 to control the rotation number of the motor 121; the motor 121 controls the sliding distance of the shaft sleeve 123 on the rotating shaft 122 through the rotation number, and then controls the sliding height of the cantilever 13, so as to control the height of the X-ray generator 14; the motor 121 is started to drive the rotating shaft 122 to move synchronously, the rotating shaft 122 is matched with the screw groove on the shaft sleeve 123 through the thread, and then drives the shaft sleeve 123 to slide vertically on the rotating shaft 122, and then drives the cantilever 13 to move synchronously through the shaft sleeve 123, the cantilever 13 drives the X-ray generator 14 installed thereon to move synchronously, and changes the height of the X-ray generator 14;

In the embodiment, the flat panel detector 5 is three, corresponding to the chest, waist and abdomen and legs respectively, and the detection and diagnosis of the above parts are realized. When the height of the X-ray generator 14 changes, the driving device 12 drives the flat panel detector 5 to slide upward through the adjusting assembly 4, the flat panel detector 5 slides vertically upward to reduce the distance between the flat panel detector 5 and the X-ray generator 14, thereby improving the imaging effect of the digital X-ray machine 1, improving the diagnosis effect of the medical staff, and the imaging effect of the digital X-ray machine 1 is related to the intensity of the X-ray. The higher the intensity of the X-ray, the higher the imaging density, and the clearer the imaging picture. The intensity of the X-ray is inversely proportional to the square of the imaging distance, that is, the smaller the distance between the flat panel detector 5 and the X-ray generator 14, the higher the intensity of the X-ray, and the clearer the detection image of the patient, which is convenient for the diagnosis of the medical staff.
