Problems solved by technology

[0004] According to the Chinese Patent No. CN 209847320 U, a kind of ulnar and radial artery puncture hand pad, the arm is fixed by the fixing belt and the palm pad, so as to avoid the influence of the arm movement on the puncture, but the existing hand pad can only be used for puncture During the operation, it is not easy to place the arm after the puncture operation. After the puncture operation, it is easy to cause swelling and subcutaneous congestion of the operated limb. It affects the movement of the limbs on the pillow, and feels extremely uncomfortable during the raising of the affected limb. Although there will be a special arm behind the hand for placement, it is necessary to move the patient's arm. pad

Embodiment 1

[0040] see Figure 1-13 , a radial artery puncture hand pad for vascular interventional surgery according to an embodiment of the present invention, comprising a main body frame 1, the two sides of the top of the main body frame 1 are fixedly connected to the limiting plate 2, and the outer cover of the main body frame 1 There is a placement frame 3, one side of the placement frame 3 is fixedly connected with two fixed blocks-4, the bottom of the fixed block-4 is fixedly connected with a connecting rod-5, and the shape design of the connecting rod-5 is similar In the U shape, the inside of the connecting rod 5 is movably connected with a movable shaft 6 through a bearing, and the outer surface of the movable shaft 6 is wrapped with a connecting band 7, and one end of the connecting band 7 is connected to the movable shaft. One 6 is fixedly connected, the other end of the connecting band 7 is connected with the collar 8, one end of the movable shaft 6 extends to the outside of ...

Embodiment 2

[0048] see figure 1 with Figure 10-11 , the adjustment mechanism includes screw rod three 35, threaded sleeve three 36, convex gear one 37, convex gear two 38, movable shaft two 39, support sleeve 40 and rotating block three 41, and the bottom of the lifting pad 18 is connected with a screw rod Three 35, the bottom end of the screw three 35 is located inside the threaded sleeve three 36, the bottom of the three threaded sleeve 36 is movably connected with the inner bottom end of the main body frame 1 through a bearing, and the outer end of the three threaded sleeve 36 is The surface is connected with a convex gear 1 37, and the convex gear 1 37 meshes with the convex gear 2 38, and the center of the circle of the convex gear 2 38 is fixedly connected with a movable shaft 2 39, and the outer surface of the movable shaft 2 39 moves through a bearing. A support sleeve 40 is connected, the outer wall of the support sleeve 40 is fixedly connected with the main frame 1, one end of...

Embodiment 3

[0051] see Figure 2-5 with Figure 8 , the placement frame 3 includes a placement rod one 46, a placement rod two 47, a connecting rod three 48 and a connecting rod four 49, the main body frame 1 is provided with a placement rod one 46 near the backing plate 25, the The other side of the main frame 1 is provided with a placement rod two 47, the two ends of the placement rod one 46 and the placement rod two 47 are connected by a connecting rod three 48, and the connecting rod three 48 is close to the placement rod one 46 One end of the side wall bottom is fixedly connected with four connecting rods 49, and the fixed block one 4 and the two fixed blocks 16 are all connected with the three connecting rods 48. The present invention places rod one 46, places rod two 47, Connecting rod three 48 and connecting rod four 49, thereby make placing frame 3 adapt to main frame 1, when not using placing frame 3, placing frame 3 can not influence the use of main body frame 1.

Abstract

The invention discloses a radial artery puncture hand pad for vascular interventional surgery, which comprises a main body frame, the outside of the main body frame is covered with a placement frame, one side of the main body frame is connected with a fixing mechanism, and the main body frame There is a through hole 1 at the top of the interior, and a raising pad is arranged inside the through hole 1, and the bottom of the raising pad is connected with the main body frame through an adjustment mechanism. Two baffle plates, the side of the main frame away from the fixing mechanism is provided with a backing plate, one side of the backing plate is fixedly connected with the connecting block three, and one side of the connecting block three is located on the main frame The inside is connected with the movable plate, and the movable plate is connected with the threaded sleeve 2, the internal thread of the threaded sleeve 2 is connected with the screw rod 2, and the outer surface of the screw rod 2 is provided with a rotating mechanism. Beneficial effects: through the combination of the main body frame and the placement frame, it is convenient to carry out the radial artery puncture operation and to place the patient's arm after operation.

Description

technical field [0001] The invention relates to the technical field of medical hand pads, in particular to a radial artery puncture hand pad for vascular interventional operations. Background technique [0002] The radial artery first passes between the brachioradialis muscle and the pronator teres, then descends between the brachioradialis tendon and the flexor carpi radialis tendon, wraps around the radial styloid process to the back of the hand, passes through the first metacarpal space to the palm, and is deep in the palm of the ulnar artery The branches anastomose to form the deep palmar arch. The lower segment of the radial artery is only covered by the skin and fascia, and it is the place where the pulse is clinically felt. [0003] Clinically, radial artery puncture is often used to collect arterial blood samples for blood gas analysis. However, due to the thinner radial artery, the difficulty of puncture is significantly increased. In order to improve the success o...
