Description

X-ray stress tester {EQUIPMENT FOR STRESS EXAMINATION FOR X-RAY}

The present invention relates to a stress testing device, and more specifically, to fix the portion to be examined so as not to move, and to apply a certain pressure to the portion to be examined to measure the rupture of joints or ligaments through X-rays. It relates to a stress test device for X-ray imaging.

In general, when capturing an X-ray image, it is very important to perform an X-ray after confirming that the patient's posture or a specific part is correctly positioned in the photographing area in order to acquire an X-ray image of the correct position. Here, the posture of the patient may include various movements to adjust the position of the patient in the photographing area as well as the movement or the movement of the patient's human body.

The rupture of a bone or ligament depends on the force, speed, and direction on the bone and ligament. Radiographic examinations are performed to find out whether the bone or ligament is ruptured, but only when the bone or ligament is ruptured, or a simple injury involving fragmentation of the bone. The stress test method for determining the abnormality according to the degree of deformation by applying a constant force is widely used.

The stress test method is a test method for determining whether the ligament is ruptured by determining the degree of deformation of the ligament through X-ray after applying a constant force to the test site as described above.

In the conventional stress test method, the doctor, the nurse, or the guardian must hold the test site of the person to be examined by hand and apply a force to perform the test. There was a problem that the test person feels pain because it is not properly fixed, and there is also a difficulty that the correct test is not made.
