DETAILED DESCRIPTION
[0017] The utility model is further described below in conjunction with the accompanying drawings and embodiments.
[0018] An adjustable support frame for PICC catheter placement, such as Figure 1-Figure 4 As shown, it includes a base 1, universal wheels 2, support rods 3, telescopic rods 4, support seat 5, rotating frame 6, support plate 7 and a rotating adjustment mechanism. Four universal wheels 2 are installed at the bottom of the base 1, and the support frame can be moved to a specified position through the universal wheels 2. The top of the base 1 is fixedly connected to the support rod 3, the top of the support rod 3 is fixedly connected to the telescopic rod 4, the top of the telescopic rod 4 is fixedly connected to the support seat 5, the telescopic rod 4 is located on the left side of the bottom of the support seat 5, and the height of the support seat 5 is adjusted by the telescopic rod 4 so that the support seat 5 can be placed flat on the bed, the top of the support seat 5 is rotatably connected to the rotating frame 6, and the top of the rotating frame 6 is fixedly connected to the support plate 7, and a rotating adjustment mechanism is connected between the support seat 5 and the support plate 7, and the angle of the support plate 7 can be adjusted through the rotating adjustment mechanism according to the patient's physical condition, so as to facilitate the use of a catheter to puncture the patient's limb veins. The rotation angle of the support plate 7 is controlled by the rotating adjustment mechanism, so that the support plate 7 is rotated to an angle suitable for the placement of the patient's limbs, and then the patient's limbs are placed on the support plate 7, and then venous puncture is performed on the patient's limbs. Some patients are not convenient to go to the puncture room. Medical staff can move the support frame to other wards through the universal wheels 2 set at the bottom of the base 1, which is convenient for the use of the device.
[0019] like Figure 1-Figure 3 As shown, the rotation adjustment mechanism includes a threaded rod 8, a handle 9, a movable ring 10, a first connecting rod 11, a connecting rod 12, a second connecting rod 13 and a guide rod 14. The threaded rod 8 is rotatably connected to the right side of the top of the support seat 5, and the handle 9 is fixedly connected to the front side of the threaded rod 8. The guide rod 14 is fixedly connected to the left side of the top of the support seat 5. The threaded rod 8 and the guide rod 14 are both connected with movable rings 10. The right movable ring 10 is threadedly connected to the threaded rod 8, and the left movable ring 10 is slidably connected to the guide rod 14. The top of the movable ring 10 is fixedly connected to the first connecting rod 11, the top of the first connecting rod 11 is rotatably connected to the connecting rod 12, and the rear end of the connecting rod 12 is rotatably connected to the second connecting rod 13. The top of the second connecting rod 13 is fixedly connected to the support plate 7. Through the connection relationship in the rotation adjustment mechanism, the rotating frame 6 can be rotated when the threaded rod 8 is rotated, thereby rotating the support plate 7.
[0020] When the rotation adjustment mechanism is used to adjust the angle of the support plate 7, the threaded rod 8 is rotated by the handle 9 to make the right-side movable ring 10 move backward, and the movable ring 10 moves backward to drive the right-side first connecting rod 11 to move backward, and the right-side connecting rod 12 rotates to make the right-side second connecting rod 13 drive the rotating frame 6 to rotate through the support plate 7. While the rotating frame 6 rotates, the left-side second connecting rod 13 drives the left-side connecting rod 12 to rotate through the support plate 7, and the left-side connecting rod 12 rotates to drive the left-side first connecting rod 11 to rotate, and the left-side first connecting rod 11 rotates to drive the left-side movable ring 10 to move forward along the guide rod 14. When the angle of the support plate 7 needs to be adjusted in the opposite direction, it is only necessary to reverse the threaded rod 8 by the handle 9. The rotation angle of the support plate 7 can be accurately adjusted through the rotation adjustment mechanism, so that the support frame can adapt to the patient's limb condition, making the support frame more humane.
[0021] like Figure 1 , Figure 3 and Figure 4 As shown, it also includes a fixed block 15 and an extension plate 16. The left and right sides of the support plate 7 are fixedly connected with the fixed blocks 15. The two fixed blocks 15 have a slide groove 151 on the opposite sides. The slide groove 151 is in a stepped shape. Two extension plates 16 are slidably connected between the slide grooves 151 on both sides. When the extension plate 16 is at the highest point of the slide groove 151, it is located at the top of the support plate 7 to reduce the support area. When the extension plate 16 is at the lowest point of the slide groove 151, the top of the extension plate 16 is flush with the support plate 7. When there is no need to extend the support plate 7, the two extension plates 16 are located at the top of the support plate 7, and the patient's limbs need to be placed on the top of the extension plate 16 for venous puncture. When the patient's limbs are longer than the support plate 7, especially when puncturing the patient's leg veins, a larger space is needed to support the patient's legs, so that the front and rear extension plates 16 move away from each other along the slide groove 151, and the two extension plates 16 then move downward along the slide groove 151 to make the two extension plates 16 flush with the support plate 7, and then the patient's limbs are placed on the extension plates 16 and the support plates 7. When the extension plates 16 need to be folded up, the two extension plates 16 can be moved in the opposite direction to reset. The extension plates 16 extend the area where the support frame contacts the patient's legs, so that the support frame can support the patient's legs to facilitate the puncture of the patient's leg veins by the catheter.
[0022] like Figure 1 and Figure 3As shown, a fixing rod 17 is also included, and the two fixing blocks 15 are fixedly connected to the fixing rod 17 on the sides away from each other, and a gap is left between the corresponding fixing rod 17 and the fixing block 15. After the patient's limbs are locally anesthetized, a restraint belt is tied to the patient's limbs, and the binding rope of the restraint belt passes through the gap between the corresponding fixing rod 17 and the fixing block 15, so that the restraint belt is fixed to the left and right fixing rods 17, so that the patient's limbs can be fixed to prevent the patient's limbs from rolling and affecting the catheter puncture into the vein.
[0023] like Figure 1 As shown, a buckle 18 is also included, and the buckle 18 is fixedly connected to the right side of the telescopic rod 4, and the buckle is located directly below the fixing seat 5. When the support frame is moved to the patient through the universal wheel 2, the support frame is connected to the bed through the buckle 18, which can fix the support frame to prevent the support frame from being moved by accident and affecting the venous puncture.
[0024] like Figure 1-Figure 4 As shown, the tops of the support plate 7 and the extension plate 16 are both provided with arc-shaped depressions. When the patient's limbs are placed on the support plate 7 and the extension plate 16, the arc-shaped surfaces of the support plate 7 and the extension plate 16 contact with the patient's limbs, so that the support plate 7 and the extension plate 16 can fit the patient's limbs better, making the support frame more humane.

The description of the above embodiments is only used to help understand the method of the present application and its core idea. At the same time, for general technical personnel in this field, according to the idea of the present application, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present application.
