[0003] Based on the above, the present inventor found that the device in the above-mentioned patent can conveniently fix the handrail during use, but when rotating the handrail, it needs to be fixed first, then the handrail can be rotated, and two hands need to be operated cooperatively, which is troublesome.

[0004] Therefore, in view of the above, the existing structure and defects are improved, and a lower limb blood vessel ultrasonic diagnostic assisting device is provided to achieve the purpose of having more practical value. UTILITY MODEL CONTENTS

[0005] To solve the above technical problems, the utility model provides a lower limb blood vessel ultrasonic diagnostic assisting device to solve the problem that the existing lower limb blood vessel ultrasonic diagnostic assisting device is troublesome when rotating the handrail.

[0006] The purpose and effect of the lower limb blood vessel ultrasonic diagnostic assisting device of the utility model are achieved by the following specific technical means:

[0007] A lower extremity vascular ultrasound diagnostic assistance device includes a support base, a reclining board mounted on the support base via a hinge, a safety belt assembly mounted on the surface of the reclining board, a telescopic cylinder mounted on the surface of the support base and connected to the bottom of the reclining board, a foot pedal mounted on the surface of the reclining board, a set of handrails rotatably mounted on the surface of the reclining board, a fixing mechanism mounted on the surface of the handrails, the fixing mechanism including a connecting rod mounted on the surface of the handrails, a sleeve rod and a spring sleeved on the surface of the connecting rod, the spring being located above the sleeve rod, one end of the spring contacting the handrail and the other end contacting the sleeve rod, a locking block mounted on the bottom of the spring, and a locking groove formed on the surface of the reclining board, a set of finger rings mounted on both sides of the sleeve rod, and the sleeve rod being limited by a limiting mechanism.

[0008] Furthermore, the limiting mechanism includes a limiting block installed on the inner wall of the sleeve rod and a limiting groove formed on the surface of the connecting rod, wherein the limiting block and the limiting groove are matched.

[0009] Furthermore, the armrest and the reclining board are connected by a detachable mechanism.

[0010] Furthermore, the detachable mechanism includes a placement groove formed on the surface of the reclining board, a placement block installed in the placement groove, and slots matching the shafts on the surface of the handrail on both the placement groove and the placement block. The placement groove also includes a threaded groove and a bolt that passes through the placement block and rotates into the threaded groove.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes a fixing mechanism. When the handrail needs to be rotated, the handrail can be held, two fingers inserted into the ring, and then the fingers bent to move the ring. The movement of the ring causes the sleeve rod to move on the connecting rod, which in turn causes the locking block to move, disengaging it from the slot. The handrail is then freed and can be rotated. To reset the handrail, the ring is pulled up, the handrail rotated, and the locking block moved above the slot. The ring is then released, and the spring resets, causing the sleeve rod to reset and the locking block to engage in the slot. This design allows the handrail to be rotated with one hand, resulting in higher efficiency. Attached Figure Description

[0029] As attached Figure 1 To be continued Figure 5 As shown:

[0030] This utility model provides a lower extremity vascular ultrasound diagnostic assistance device, including a support base 1, a reclining board 2 mounted on the support base 1 via a hinge, a safety belt assembly 3 mounted on the surface of the reclining board 2, a telescopic cylinder 4 mounted on the surface of the support base 1, the telescopic cylinder 4 being connected to the bottom of the reclining board 2, a footrest 5 mounted on the surface of the reclining board 2, a set of handrails 6 rotatably mounted on the surface of the reclining board 2, a fixing mechanism 7 mounted on the surface of the handrails 6, the fixing mechanism 7 including a connecting rod 701 mounted on the surface of the handrails 6, a sleeve rod 702 and a spring 703 sleeved on the surface of the connecting rod 701, the spring 703 being located above the sleeve rod 702, one end of the spring 703 contacting the handrail 6, and the other end contacting the sleeve rod 702, a locking block 704 mounted on the bottom of the spring 703, and a locking groove 705 formed on the surface of the reclining board 2, a set of finger rings 706 mounted on both sides of the sleeve rod 702, and the sleeve rod 702 being limited by a limiting mechanism 8.

[0031] With the use of the fixing mechanism 7, when the handrail 6 needs to be rotated, one can hold the handrail 6 and place two fingers into the ring 706, then bend the fingers to move the ring 706. The movement of the ring 706 will cause the sleeve rod 702 to move on the connecting rod 701. The movement of the sleeve rod 702 will cause the locking block 704 to move, thereby disengaging the locking block 704 from the slot 705. At this time, the handrail 6 is unrestrained and can be rotated. When the handrail 6 needs to be reset, the ring 706 is pulled up, and then the handrail 6 is rotated to move the locking block 704 above the slot 705. Then the ring 706 is released. At this time, the spring 703 resets, causing the sleeve rod 702 to reset, thereby causing the locking block 704 to engage in the slot 705. With the above design, the handrail 6 can be rotated with one hand, which is more efficient.

[0032] The limiting mechanism 8 includes a limiting block 801 installed on the inner wall of the sleeve rod 702 and a limiting groove 802 formed on the surface of the connecting rod 701, wherein the limiting block 801 and the limiting groove 802 are matched.

[0033] By using the limiting block 801 and the limiting groove 802, the sleeve 702 will not rotate when it moves, thereby preventing the position of the ring 706 from shifting.

[0034] The armrest 6 and the reclining board 2 are connected by a detachable mechanism 9.

[0035] The detachable mechanism 9 includes a placement groove 901 formed on the surface of the reclining board 2, a placement block 902 installed in the placement groove 901, and slots 903 on the surfaces of the placement groove 901 and the placement block 902 that match the shafts on the surface of the handrail 6. A threaded groove 904 is formed in the placement groove 901, and a bolt 905 is also included. The bolt 905 passes through the placement block 902 and rotates into the threaded groove 904.

[0036] With the use of the detachable mechanism 9, when it is necessary to remove the handrail 6, the bolt 905 can be unscrewed, and then the placement block 902 can be removed. At this time, the handrail 6 can be removed, and the sleeve rod 702 and spring 703 can also be removed for easy replacement, which improves practicality.

[0037] The surface of the reclining board 2 is fitted with a headrest 10.

[0038] The use of headrest 10 can improve patient comfort.

[0039] The lying board 2 is made of plastic.

[0040] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
