Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to an upper arm fixation frame used in conjunction with a CT examination bed. Background Technology

[0002] In medical practice, when performing upper limb and hand scans on patients, the patient usually needs to lie flat on the scanning table with their hands placed at their sides. However, some patients are taller, wider, or have larger hips, so when examining both upper limbs, their forearms exceed the maximum range of the CT scan. Currently, to address this issue, many doctors recommend that patients place their upper limbs flat on their abdomen. While this allows for scanning of both upper limbs, it is affected by breathing during the scan, severely impacting the scan results.

[0003] Chinese Patent Application No. CN201120099253.0 discloses an upper limb support and fixation frame for CT scans. The frame consists of an arch bridge and a fixing part. The bridge body of the arch bridge spans across the upper abdomen of the human body and its length is longer than the waist of the human body. The height of the bridge piers is slightly higher than the height of the human body's abdomen and back. A retractable structure and a locking structure are provided on each of the left and right bridge piers. The fixing part consists of two square thin plates, which are connected to the bottom of the left and right bridge piers respectively by hinges. Soft pads are attached to the support surface of the bridge body.

[0004] Although the upper limb support and fixation frame can effectively support and fix the upper limb, patients can only maintain the position of the upper limb through their own consciousness. When there is an injury to the upper limb, it is difficult to maintain the posture. Therefore, we propose an upper arm fixation frame that is used in conjunction with a CT examination bed to solve the above problems. Utility Model Content

This embodiment provides an upper arm fixation frame for use with a CT examination bed, including two support plates 1. The middle part of one end of the two support plates 1 is respectively fixedly connected to a hinge seat 2. The hinge seat 2 is respectively hinged to a mounting seat 3. The mounting seat 3 is respectively fixedly connected to one end of a telescopic member 4. The other end of the telescopic member 4 is respectively fixedly connected to both sides of one end face of a support bar 5. An adjustment slide 6 is provided through the middle of the support bar 5. Two threaded rods 9 are slidably sleeved in the adjustment slide 6. One end of the two threaded rods 9 is respectively rotatably connected to a hinge shaft 12. The end of the hinge shaft 12 away from the threaded rods 9 is respectively fixedly connected to a fixing frame 7. An inflatable airbag 8 is fixedly installed on both sides of the fixing frame 7.

[0020] The other ends of the two threaded rods 9 are connected to nuts 10 through a threaded structure. Nuts 10 are movably disposed in wide grooves 11, which are opened on one side of the middle of the support bar 5.

[0021] The support plate 1 is inserted flush with both sides of the CT examination table. According to the patient's body shape, the telescopic component 4 is operated to raise or lower the support bar 5. When the appropriate height is reached, the telescopic component 4 is fixed, thus keeping the height position of the support bar 5 fixed. The patient's body or head is located at the bottom of the support bar 5. Then, the fixing frame 7 is adjusted to the required fixed position. The threaded rod 9 slides in the adjusting slide 6. After the adjustment is completed, the nut 10 is tightened, causing the fixing frame 7 to abut against the top wall of the support bar 5. The fixing frame 7 is fixed in position by friction. Then, the patient's upper limb is placed flat or raised, so that the upper limb is located inside the fixing frame 7. The inflatable airbag 8 is inflated by the air pump, causing the inflatable airbag 8 to expand. The inflated inflatable airbag 8 clamps and fixes the patient's upper limb, keeping the patient's upper limb unchanged, which facilitates the CT examination operation.

[0022] Example 2

[0023] Reference Figure 1-3 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. Specifically, the two supporting thin plates 1 have the same size and structure. The consistent structure ensures the shapeability and stability of the supporting thin plates 1. The supporting thin plates 1 are relatively thin, which makes it easy to insert them into both sides of the CT examination bed frame. Then, in accordance with the patient's weight, the supporting thin plates 1 are kept fixed.
