[0033] The utility model provides a portable arteriovenous puncture hand supporting plate 300 as shown in Figures 1 to 2 The utility model provides a portable arteriovenous puncture hand supporting plate 300 as shown in

[0034] The portable arteriovenous puncture hand supporting plate 300 mainly includes a base 100, a lifting module 200 and a hand supporting plate 300.

[0035] The lifting module 200 is arranged on the base 100, the hand supporting plate 300 is arranged on the lifting module 200, the base 100 is used to be adjacent to the bed, and the hand supporting plate 300 is used to support the upper limbs. The hand supporting plate 300 is driven by the lifting module 200 to move towards or away from the base 100, and the hand supporting plate 300 has a length direction 600 arranged along the head-to-tail direction of the bed.

[0036] In actual use, the base 100 and the hand supporting plate 300 are close to the operating bed, the common bed or the chair, etc., and the patient can place the upper limbs on the hand supporting plate 300 for support, so as to facilitate the medical staff to perform the operation such as arterial and venous puncture. The hand supporting plate 300 has a length direction 600 arranged along the head-to-tail direction of the bed, which can increase the contact area of the hand supporting plate 300 and the upper limbs of the patient, improve the comfort of the patient, and also improve the stability of supporting the upper limbs of the patient.

[0037] The patent with publication number CN221205460U discloses a nursing hand supporting plate 300, which comprises a hand supporting plate 300 and a supporting assembly. The supporting assembly is provided with a fixing device at an end away from the hand supporting plate 300, and the fixing device is used for fixing the supporting assembly to the edge of the sickbed. However, the disassembly and assembly need to repeatedly rotate the screw, which is relatively inconvenient, and the hand supporting plate 300 cannot be used independently of the operating bed, and the flexibility is poor.

[0038] The utility model discloses a hand supporting plate 300 is set up on the base 100 through the lifting module 200, which can be used without the help of the track lock and other fixing devices to fix on the operating bed, and the height of the hand supporting plate 300 can be adjusted with the help of the lifting module 200, so that the hand supporting plate 300 can be adapted to operating beds of different heights, and can be used independently without the cooperation of the operating bed during use, and the flexibility is high.

[0039] In some embodiments, as shown in Figures 1 to 2 The lifting module 200 comprises a scissor assembly 210.

[0040] A plurality of sliding blocks 220, the two ends of the scissor assembly 210 are respectively hinged to the plurality of sliding blocks 220.

[0041] Two slide rails 230, the two slide rails 230 are respectively arranged on the opposite surfaces of the base 100 and the hand supporting plate 300, and the plurality of sliding blocks 220 are respectively slidingly arranged on the two slide rails 230.

[0042] In some embodiments, as shown in Figures 1 to 2 The scissor assembly 210 comprises two supporting rods 211, the two supporting rods 211 are cross-arranged, and the two ends of the two supporting rods 211 are respectively hinged to the plurality of sliding blocks 220.

[0043] A limiting piece 212 is arranged between the two supporting rods 211, and the two supporting rods 211 are respectively rotationally arranged on the limiting piece 212.

[0044] A limiting rod 213 is arranged on the base 100 towards the hand supporting plate 300, and the limiting piece 212 is slidingly arranged on the limiting rod 213.

[0045] In practical use, the distance between the base 100 and the handle plate 300 (i.e., the height of the handle plate 300) can be controlled by adjusting the included angle of the two support rods 211. Changing the included angle of the two support rods 211 will also change the distance between the ends of the two support rods 211 facing the same direction. Figures 1 to 2 As shown, when the height of the hand support plate 300 is raised, the distance between the two sliders 220 on the base 100 or the hand support plate 300 decreases. Since the length of the slide rail 230 remains constant, the two sliders 220 will move synchronously along the corresponding slide rail 230, causing the base 100 and the hand support plate 300 to easily experience relative displacement (e.g., the base 100 remains stationary while the hand support plate 300 slides to the left or right), resulting in instability. By setting a limiting rod 213, the intersection of the two support rods 211 can always be on the limiting rod 213. The limiting rod 213 is preferably set vertically, which makes it less likely for the base 100 and the hand support plate 300 to move relative to each other, and the lifting and lowering of the hand support plate 300 can maintain stability. Specifically, the length of the limiting rod 213 can be set according to actual needs, or the limiting rod 213 can be set as a telescopic rod.

[0046] In some embodiments, such as Figure 2 As shown, the lifting module 200 also includes: an adjusting screw 240, which is disposed on the hand support plate 300 along the length direction 600. The adjusting screw 240 is connected to a plurality of sliders 220 located on the hand support plate 300. The plurality of sliders 220 located on the hand support plate 300 are driven by the adjusting screw 240 to move toward the center of gravity of the hand support plate 300.

[0047] In practical use, the distance between the base 100 and the handplate 300 (i.e., the height of the handplate 300) can be controlled by adjusting the included angle of the two support rods 211. The height of the handplate 300 can be changed by adjusting the distance between several sliders 220 through the screw 240. Since several sliders 220 all move towards the center of gravity of the handplate 300, the lifting and lowering of the handplate 300 can maintain good stability during lifting and lowering.

[0048] In some embodiments, such as Figures 1 to 2 As shown, the lifting module 200 also includes an adjustment knob 250, one end of an adjustment screw 240 is connected to the adjustment knob 250, and the adjustment knob 250 is used to drive the adjustment screw 240 to rotate.

[0049] Preferably, the adjustment knob 250 is located at the end of the armrest 300 facing the foot of the bed, which makes it convenient for medical staff to adjust and also reduces the probability of the patient bumping into it.

[0050] In some embodiments, such as Figures 1 to 2As shown in FIG. 1, the portable arteriovenous puncture hand rest plate 300 further comprises a wrist pad 400, the wrist pad 400 comprises a wrist pad body 410, the wrist pad body 410 is slidingly arranged on the hand rest plate 300 along the length direction 600, and an end surface of the wrist pad body 410 away from the base 100 forms a wrist pad surface and is used for supporting a wrist.

[0051] In some embodiments, as shown in FIG. 1, the portable arteriovenous puncture hand rest plate 300 further comprises a strap, the strap is slidingly arranged on the hand rest plate 300 along the length direction 600, and the strap is used for fixing an upper limb of a patient. Figures 1 to 2
