[0008] When using the above structure, the patient's elbow is placed between the two elbow positioning plates. The geared motor is activated by a switch, driving the screw to rotate. The two sleeves then move the two elbow positioning plates closer together. The elbow positioning plates move the hand positioning plate, causing the arc-shaped strip to press against the patient's wrist. The elbow positioning plates also move the upper arm positioning plate, causing the silicone pad to press against the patient's upper arm. The gap between the two elbow positioning plates can be adjusted, thus firmly binding the patient's wrist and providing multi-point synchronous fixation of the patient's elbow.

[0009] Preferably, a sliding support assembly is installed at the rear of the support frame; the sliding support assembly includes a support plate fixedly installed at the rear of the support frame, and a reinforcing slide plate is fixedly connected to the top of the support plate, and two arc-shaped support strips are fixedly installed on one side of the outer wall of the reinforcing slide plate; a reinforcing support strip is fixedly connected to one side of each arc-shaped support strip, and a support column is fixedly installed between the two arc-shaped support strips, and the reinforcing slide plate and the support plate are slidably connected to the elbow positioning plate.

[0010] According to the structure above, when in use, the support frame supports the support plate, the support plate supports the reinforced sliding plate, and the reinforced support strip reinforces the arc-shaped support strip. The support column can provide lateral firm support for the two reinforced support strips. The support plate and the reinforced sliding plate can provide guide sliding support for the two elbow positioning plates, and stably increase the stability of the two elbow positioning plates when they move.

[0011] The technical effects and advantages of this utility model are as follows: This invention employs a multi-point fixation mechanism. The patient's elbow is placed between two elbow positioning plates. A geared motor drives a screw to rotate, which in turn causes two sleeve blocks to move closer together under the force of the threaded transmission. The elbow positioning plate causes the central positioning strip to press against the middle of the patient's elbow, the elbow positioning plate causes the hand positioning plate to press the arc-shaped strip against the patient's wrist, and the elbow positioning plate causes the upper arm positioning plate to press the silicone pad against the patient's upper arm. This allows for multi-point synchronous fixation of the patient's elbow, improving both binding efficiency and binding stability. 2.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] As attached Figure 1-5 The present invention relates to an elbow fixation device for ultrasound imaging, which is equipped with a multi-point fixation mechanism. The multi-point fixation mechanism enables simultaneous fixation of the patient's elbow at multiple points, which not only improves the binding efficiency but also enhances the binding firmness. The specific structural configuration of the multi-point fixation mechanism is as follows.

[0020] In this embodiment, as shown in the appendix Figure 1-3As shown, the multi-point fixing structure includes two sleeve blocks 4 threaded on the outer wall of the screw 2. Each sleeve block 4 has an elbow positioning plate 5 fixedly connected to its top end. The elbow positioning plate 5 is fixedly connected to a middle positioning strip 7. Above the middle positioning strip 7 is a large arm positioning plate 6 fixedly connected to the elbow positioning plate 5. On one side of the middle positioning strip 7 is a hand positioning plate 8 fixedly connected to the elbow positioning plate 5.

[0021] In this embodiment, the elbow fixation device for ultrasound imaging is used by first inserting bolts into the mounting holes 13 inside the mounting block 12 to fix the mounting block 12 on the ultrasound imaging platform. The patient's elbow is then placed between the two elbow positioning plates 5. The geared motor 3 is activated via switch 14, driving the screw 2 to rotate. The screw 2 causes the two sleeve blocks 4 to move closer together under the force of the threaded transmission. The two sleeve blocks 4 then move the two elbow positioning plates 5 closer together. The elbow positioning plates 5 cause the central positioning strip 7 to press against the middle of the patient's elbow. The elbow positioning plates 5 also cause the hand positioning plate 8 to press the arc-shaped strip 10 against the patient's wrist. Finally, the elbow positioning plates 5 cause the upper arm positioning plate 6 to press the silicone pad 9 against the patient's upper arm. This allows adjustment of the gap between the two elbow positioning plates 5, thus firmly binding the patient's wrist and achieving multi-point synchronous fixation of the patient's elbow. After the patient's elbow is fixed, ultrasound imaging is performed.

[0022] In this embodiment, as shown in the appendix Figure 2-3 As shown, a silicone pad 9 is fixedly connected to the inner wall of the upper arm positioning plate 6, and the inner wall of the silicone pad 9 is made smooth. This allows the upper arm positioning plate 6 to press the silicone pad 9 against the patient's upper arm, achieving a firm lock on the upper arm. An arc-shaped strip 10 is fixedly connected to the outer wall of the hand positioning plate 8, and one side of the hand positioning plate 8 has a support plate 11 fixedly connected to the elbow positioning plate 5; a gap is opened between the two support plates 11. This allows the support plate 11 to support the patient's wrist, and the hand positioning plate 8 to press the arc-shaped strip 10 against the patient's wrist. Two mounting blocks 12 are fixedly installed at the front of the support frame 1, and each mounting block 12 has a mounting hole 13 on its inner wall; a switch 14 is fixedly connected to the other side of the support frame 1. This allows bolts to be inserted into the mounting holes 13 inside the mounting blocks 12 to fix the mounting blocks 12 to the ultrasound imaging table, thus fixing the support frame 1.

[0023] In this embodiment, as shown in the appendix Figure 3-5As shown, a sliding support assembly is installed at the rear of the support frame 1; the sliding support assembly includes a support plate 15 fixedly installed at the rear of the support frame 1, and a reinforcing slide plate 16 is fixedly connected to the top of the support plate 15. Two arc-shaped support bars 17 are fixedly installed on one side of the outer wall of the reinforcing slide plate 16; a reinforcing support bar 18 is fixedly connected to one side of each arc-shaped support bar 17, and a support column 19 is fixedly installed between the two arc-shaped support bars 17. The reinforcing slide plate 16 and the support plate 15 are slidably connected to the elbow positioning plate 5.

[0024] According to the structure above, when in use, the support frame 1 supports the support plate 15, the support plate 15 supports the reinforced slide plate 16, and the reinforced support strip 18 reinforces the arc-shaped support strip 17, the arc-shaped support strip 17 supports the reinforced slide plate 16, and the support column 19 can provide lateral and firm support for the two reinforced support strips 18. In this way, the support plate 15 and the reinforced slide plate 16 can provide guiding and sliding support for the two elbow positioning plates 5, which stabilizes and increases the stability of the two elbow positioning plates 5 when they move, and makes the elbow support more stable.
