[0021] Please refer to Figure 3 and Figure 4As shown in the figure, a pressure intensifying cylinder 106 is fixedly installed on the inner side wall of the above-mentioned U-shaped frame 4. A second hose 104 is communicated with the side surface of the pressure intensifying cylinder 106. The bottom end of the pressing rod 109 movably penetrates through the pressure intensifying cylinder 106 and is fixedly installed with a piston 105. The piston 105 is slidably connected with the inner wall of the pressure intensifying cylinder 106. By controlling the extension of the extending end of the first electric push rod 108, the first shift lever 107 drives the L-shaped plate 101 to turn over, so that the mask 103 is turned out from the groove 2. When the extending end of the first electric push rod 108 is at the longest, the mask 103 is at the set working position. Then, let the patient lie on the CT scanning bed, and the mask 103 is located above the patient's face. Oxygen is injected into the mask 103 through the first hose 102 by an external oxygen supply device. The oxygen blown out from the mask 103 facilitates the patient to inhale oxygen during the CT scanning process, so that the patient can relieve the tension caused by holding urine, thereby avoiding the movement artifacts of the scanned part caused by accelerated breathing and affecting the image quality.

[0022] Please refer to Figure 2 and Figure 5 As shown in the figure, the above-mentioned lifting mechanism 5 includes a moving seat 504 slidably connected with the bottom of the inner wall of the U-shaped frame 4 through a guide rail 510.

The positioning tool 3 is a prior art.

[0028] Working principle: When the present invention is in use, first, as Figure 1 and Figure 2 shown, the U-shaped frame 4 is placed at the placement station of the CT scanning bed, and the U-shaped frame 4 is fixed on the CT scanning bed through the two positioning tools 3; as Figure 3 and Figure 4 shown, by controlling the extension end of the first electric push rod 108 to extend, the first lever 107 drives the L-shaped plate 101 to flip, so that the face mask 103 flips out of the groove 2; as Figure 2 shown, when the extension end of the first electric push rod 108 is at the longest, the face mask 103 is at the set station, and then the patient lies on the CT scanning bed, and the face mask 103 is located above the patient's face. Oxygen is injected into the face mask 103 through the first hose 102 by an external oxygen supply device, and the oxygen blown out from the face mask 103 facilitates the patient to inhale oxygen during CT scanning, so that the patient can relieve the tension caused by urine retention, thereby avoiding the movement artifacts of the scanned part caused by accelerated breathing and affecting the image quality. At this time, as Figure 3 and Figure 4 shown, the pressing rod 109 drives the piston 105 to descend, and the air in the pressure increasing cylinder 106 is squeezed into the leather bag 503 through the second hose 104 to make it inflated; as Figure 5 and Figure 6As shown, then control the extension end of the second electric push rod 506 to extend to the longest, so that the second lever 509 drives the two support plates 507 to flip until they contact the corresponding limit plates 505, and support the two forearms of the patient's upper limb through the two positioning frames 508. During this process, by horizontally moving the moving seat 504, the support pad 502 provides support for the joint of the patient's upper limb, and cooperates with the inflated leather bag 503 to lift the two upper arms of the patient's upper limb. To sum up, the positioning frame 508, the support pad 502 and the leather bag 503 provide support and lifting for various parts of the patient's upper limb, improving the comfort of the patient, avoiding the patient exerting force and affecting normal urine retention, and further ensuring the accuracy of CT scanning; As Figure 1 and Figure 2 shown, when the patient completes the CT scan, the extension ends of the first electric push rod 108 and the second electric push rod 506 contract and reset, facilitating the folding and storage of the L-shaped plate 101 and the support plate 507 back to their original positions to prevent affecting the subsequent use by other patients.
