The bottom plate 1 is formed with a first area 11 and a second area 12, and the first area 11 and the second area 12 are arranged side by side horizontally. The first area 11 is used to pad on the human back, and the second area 12 is used to place the human upper limb. In a preferred embodiment, the first area 11 is arranged at one end side of the second area 12, and the two are integrally formed. The upper limb limiting component 2 is arranged in the second area 12 and can move in a direction towards or away from the first area 11. A limiting space 4 for limiting and placing the upper limb is formed by enclosing between the upper limb limiting component 2 and the bottom plate 1. The wrist limiting component 3 is arranged at one end of the second area 12 away from the first area 11 and can move along the length direction of the second area 12. The wrist limiting component 3 has a concave position 311 for placing the human wrist.

[0031] Among them, the bottom plate 1 is made of a transparent PC board, also called a polycarbonate hollow board, which is processed from a high-performance engineering plastic - polycarbonate (PC) resin, and has the characteristics of high transparency, light weight, impact resistance, sound insulation, heat insulation, flame retardancy, anti-aging, etc. The material properties of the bottom plate 1 have sufficient strength and stability to ensure that the bottom plate 1 will not deform or move during the operation, and improve the comfort of the patient during the operation.

[0032] In an alternative embodiment, such as Figure 1 and Figure 4As shown, the bottom plate 1 is provided with a first sliding groove 13 and a second sliding groove 14. The upper limb limiting component 2 moves along the first sliding groove 13, and the wrist limiting component 3 moves along the second sliding groove 14. The first sliding groove 13 extends along the width direction of the bottom plate 1, and the second sliding groove 14 extends along the length direction of the bottom plate 1. In order to prevent the sliding ends of the upper limb limiting component 2 and the wrist limiting component 3 from protruding from the surface of the bottom plate 1, two relief grooves 5 are provided on the surface of the bottom plate 1 facing away from the upper limb limiting component 2, corresponding to the first sliding groove 13 and the second sliding groove 14 respectively, and the size is larger than its corresponding sliding groove. During implementation, the sliding ends of the upper limb limiting component 2 and the wrist limiting component 3 are located in the relief grooves 5, which can prevent the bottom plate 1 from being unevenly placed during use and from pressing against the patient's arm during the operation, improving the comfort of the patient. At the same time, the design of the adjustable position of the base 21 enables the arm support plate to be adjusted according to patients of different body types, having better adaptability.

[0033] In an alternative embodiment, as Figure 2 shown, the upper limb limiting component 2 includes a base 21 and a limiting member 22. The limiting member 22 is rotatably connected to the base 21 and rotates towards or away from the bottom plate 1. The base 21 is slidably disposed in the first sliding groove 13. Both the base 21 and the limiting member 22 are made of polycarbonate. The length of the base 21 is 10 cm and the width is 5 cm. Two connecting portions 211 protrude from the surface of the base 21 facing away from the bottom plate 1. The two connecting portions 211 are symmetrically arranged. The connecting portion 211 is provided with a jack corresponding to the limiting member 22. In this embodiment, the limiting member 22 is formed by bending a round rod of polycarbonate. The two end portions of the limiting member 22 are inserted into the jacks on the corresponding side, enabling the limiting member 22 to rotate relative to the base 21. Further, the limiting member 22 is integrally U-shaped. The two sides of the U-shaped limiting member 22 are convex arc-shaped structures, and together with the bottom plate 1, they enclose the limiting space 4. The limiting member 22 can flexibly adjust the angular position of the baffle according to the patient's weight and obesity degree, the size of the upper limb, and the surgical requirements. That is, the limiting member 22 can rotate and open relative to the bottom plate 1. After the arm is placed, the limiting member 22 rotates towards the bottom plate 1 to play a role in fixing the arm and preventing the arm from abducting, which is beneficial for the surgeon to perform interventional surgery operations. In this embodiment, two sets of upper limb limiting components 2 are provided and are arranged in parallel along the length direction of the bottom plate 1.

[0034] In an alternative embodiment, as Figure 4As shown, the surface of the base 21 away from the limiter 22 is provided with a first slider 23, and the base 21 moves along the first slide groove 13 through the first slider 23. The cross section of the first slider 23 is ┴-shaped, one end of the first slider 23 is connected to the surface of the base 21 facing the bottom plate 1, and the other end is penetrated through the bottom plate 1, and moves along the first slide groove 13. In accordance with the size setting at the first slide groove 13, the surface of the end of the first slider 23 away from the base 21 is flush with the surface of the bottom plate 1. Furthermore, the end of the first slider 23 away from the base 21 is a detachable structure. After the base 21 and the first slider 23 are partially assembled and installed in the first slide groove 13, the detachable end of the first slider 23 is installed to stably install the base 21 in the first slide groove 13.

[0035] In an optional embodiment, if Figure 3 As shown, the base 21 is provided with a knob 6, and the bottom plate 1 is provided with a limiting groove 15 corresponding to the knob 6. There are multiple limiting grooves 15, and the multiple limiting grooves 15 are arranged side by side and the arrangement direction is consistent with the extension direction of the first slide groove 13. The end of the knob 6 is penetrated through the bottom plate 1 and screwed into the limiting groove 15 to lock the base 21 to the bottom plate 1. The base 21 is provided with a threaded groove, and the threaded hole is vertically arranged relative to the bottom plate 1. The knob 6 is composed of a stud and a gripping cap, one end of the stud is connected to the gripping cap, and the other end is screwed into the threaded groove, and then clamped in the limiting groove 15. At this time, the base 21 is in a stable docking state. In this state, the base 21 is immovable. When the position of the base 21 needs to be adjusted, the knob 6 is rotated to disengage the end of its stud from the limiting groove 15. After moving the base 21 to a suitable position, the knob 6 is rotated again to the corresponding limiting groove 15 to fix the position of the base 21.

[0036] In an optional embodiment, if Figure 4 As shown, the wrist limit assembly 3 includes a U-shaped pad 31 and a second slider 32, the second slider 32 is slidably disposed in the second slide groove 14, and the U-shaped pad 31 is disposed on the surface of the second slider 32 away from the bottom plate 1. The cross section of the second slider 32 is a ┴-shaped structure, and its installation method is the same as that of the first slider 23, which is convenient for medical staff to adjust the position of the U-shaped pad 31 according to the length of the patient's upper limb, that is, to push the U-shaped pad 31 to move along the length direction of the second slide groove 14, so that the patient's wrist is just placed on the U-shaped pad 31, which plays a role in limiting the movement of the patient's wrist, and can further expose the radial artery for radial artery puncture. In this embodiment, the length of the U-shaped pad 31 is 6 cm, the width is 5 cm, the depth of its concave surface is 2 cm, and the height is 3 cm.

[0037] In an optional embodiment, if Figure 2As shown, a soft cushion layer 33 is provided on the U-shaped surface of the U-shaped cushion block 31. The soft cushion layer 33 is made of soft materials such as silica gel and cotton cloth, and can be installed by hot melting or pasting. The setting of the soft cushion layer can avoid skin pain and injury of the wrist due to a long operation time, and improve the comfort of the patient during the operation.

[0038] In an alternative embodiment, as Figure 2 shown, a anti-detachment strap 7 is further provided. One end of the anti-detachment strap 7 is arranged on the periphery of the first sliding groove 13 and is close to the first area 11. A plurality of limiting holes 71 are formed along the length direction of the anti-detachment strap 7. A button 72 is arranged at the free end of the anti-detachment strap 7. The free end of the anti-detachment strap 7 is wound around one end of the limiting member 22 away from the base 21, and the button 72 is buckled in the limiting hole 71. The anti-detachment strap 7 is made of nylon or polyester material, has high strength and wear resistance, and is not easy to deform. After the arm is placed on the arm support plate, the anti-detachment strap 7 is used to limit the movement of the limiting member 22, avoid the self-opening of the limiting member 22, and improve the fixing effect.

[0039] In an alternative embodiment, the bottom plate 1 is integrally in an L-shaped structure. The total length of the bottom plate 1 is 130 cm, and its long side width is 45 cm, short side width is 30 cm, and thickness is 2 mm. During the operation, a part of the long side of the bottom plate 1 is padded under the patient's back, which can play a fixing role. More of the bottom plate 1 is padded under the back, and the fixing effect is obvious. At the same time, it does not affect the surgical operation part of the short side of the bottom plate 1. The exposed part of the catheter for coronary intervention operation and the connecting parts 211 of the guide wire and catheter used are all inside the bottom plate 1, providing a stable plane support platform for the surgical operation and facilitating the operator to perform the interventional operation.

[0040] During use, the first area 11 of the arm support plate is padded on the patient's back. After pushing the base 21 to move along the first sliding groove 13 to a suitable position, the position is locked by the knob 6. The limiting member 22 is rotated to be opened, and the patient's arm is placed between the bottom plate 1 and the limiting member 22. The anti-detachment strap 7 is used to limit the movement of the limiting member 22, and the position of the U-shaped cushion block 31 is adjusted while adjusting the base 21.

[0041] In summary, by providing the bottom plate 1, the upper limb limiting component 2 and the wrist limiting component 3, the arm support plate can effectively prevent the movement of the arm, avoid the occurrence of complications caused by the movement of the patient, such as blood vessel injury or misoperation of surgical instruments, reduce the surgical risk, and improve the surgical accuracy; it can quickly adjust the positions of the upper limb limiting component 2 and the wrist limiting component 3 according to the patient's own conditions to meet the surgical needs, shorten the surgical preparation time, and improve the surgical efficiency; and improve the comfort of the patient during the operation.
