[0031] In some embodiments, base 10 serves as the foundation for the entire support cushion 1, serving to place and secure other components while also providing a stable support surface. An adjustment assembly is connected to base 10 and features a height-adjustable end, allowing medical personnel to adjust the wrist and arm height to suit the patient's needs for optimal puncture angle. It is worth noting that the adjustment assembly can be mechanical, such as a manual lift mechanism, or electric, driven by a motor to achieve height adjustment.

[0032] The support assembly includes a first support part and a second support part. Both the first support part and the second support part are suitable for contacting the patient's arm to provide necessary support to the patient's arm. The second support part is rotatably arranged at one end of the first support part. Thus, the second support part can be appropriately adjusted according to the shape of the patient's arm and the puncture needs.

[0033] It is understandable that medical staff can adjust the positions of the first support part and the second support part so that the patient's wrist and arm are in the most suitable puncture position, thereby reducing the patient's discomfort during the puncture process; at the same time, the height adjustment function of the adjustment component allows medical staff to easily adjust the first support part and the second support part to the optimal puncture angle, so that the patient's radial artery can be fully exposed, improving the convenience and efficiency of the puncture operation.

[0034] It should be noted that the design of the support component ensures the stability and comfort of the patient's arm, helps to reduce arm movement during the puncture process, and reduces the risk of puncture complications; at the same time, the support pad 1 of the present application has good adaptability, and the support pad 1 can be suitable for patients of different body shapes and arm sizes, thereby improving versatility and practicality.

[0035] In summary, the adjustability of the first support part and the second support part of the support assembly ensures that personalized adjustments can be made according to the specific circumstances of each patient; and through reasonable adjustment of the first support part and the second support part, it can be ensured that the patient's arm is properly supported during the puncture process, reducing unnecessary pressure and discomfort; at the same time, the stability and adjustability of the support pad 1 help to reduce unnecessary movement of the arm during puncture, reducing the risk of puncture failure and complications.

[0036] It is worth mentioning that the second support part is rotatably provided at at least one end of the first support part in the length direction. Here, the second support part can be constructed as one. In this case, the second support part is rotatably provided at one end of the first support part in the length direction, and the second support part is suitable for supporting the patient's forearm or back of the hand; or the second support part can be constructed as two. In this case, the two second support parts are rotatably provided at the two ends of the first support part in the length direction, and the two second support parts are suitable for supporting the patient's forearm and back of the hand respectively.

[0037] According to the radial artery puncture support pad 1 of the present invention, its adjustment component can adjust the height of the support component, and the second support part of the support component can be rotatably arranged to move at least in the length direction of the first support part. Medical staff can adjust the height of the first support part and the second support part according to actual conditions, as well as adjust the rotation angle of the second support part relative to the first support part, so that the patient's wrist and arm are in the most suitable puncture position, which improves the convenience and efficiency of the puncture operation. At the same time, the first support part and the second support part can stably support the patient's arm, reduce unnecessary pressure and discomfort on the patient's arm, and ensure the stability and comfort of the patient's arm.

[0038] Embodiment 2: Based on Embodiment 1, this embodiment includes a support assembly including: a base plate 31, a support rod, a first telescopic rod 33, a first support plate 34 and a second support plate 35. The base plate 31 is connected to the adjustment end, the support rod is connected to the base plate 31, the first telescopic rod 33 is rotatably connected to the base plate 31, the first support plate 34 is constructed as a first support portion, the first support plate 34 is connected to the support rod, the second support plate 35 is constructed as a second support portion, and the second support plate 35 is rotatably connected to the first support plate 34; wherein the free end of the first telescopic rod 33 is rotatably connected to the free end of the second support plate 35, and the free end of the first telescopic rod 33 can be selectively moved toward or away from the base plate 31.

[0039] In some embodiments, the base plate 31 is connected to the adjustment end of the adjustment assembly, and the base plate 31 serves as the basic part of the support assembly, playing a connecting and supporting role; the support rod is connected to the base plate 31, and the support rod is used to support the first support plate 34 to ensure that the first support plate 34 can stably support the patient's wrist; the first telescopic rod 33 is rotatably connected to the base plate 31, and the free end of the first telescopic rod 33 is rotatably connected to the free end of the second support plate 35. Thus, the free end of the first telescopic rod 33 can be selectively moved toward or away from the base plate 31 as needed, so that the position (angle) of the second support plate 35 relative to the first support plate 34 can be adjusted to adapt to different arm sizes and puncture requirements.

[0040] The first support plate 34 is constructed as the first support part, and the first support plate 34 is rotatably connected to the support rod. The first support plate 34 is mainly used to support the patient's wrist to ensure that the wrist is in the optimal puncture position; the second support plate 35 serves as the second support part, and the second support plate 35 is rotatably connected to the first support plate 34. The second support plate 35 is used to support other parts of the patient's arm, such as the forearm or the back of the hand, to ensure the stability of the arm.

[0041] Therefore, medical staff can adjust the height of the entire support assembly through the adjustment assembly to ensure that the patient's wrist is at the optimal puncture angle; the rotational connection between the first support plate 34 and the second support plate 35 makes it possible to adjust the support angle according to the specific situation of the patient's arm, so that the patient's arm is in the most appropriate position and reduces patient discomfort; at the same time, the adjustable feature of the first telescopic rod 33 enables the second support plate 35 to be extended and retracted as needed to adapt to the arm sizes of different patients, thereby improving the versatility of the support pad 1.

[0042] In summary, the radial artery puncture support pad 1 of the present application not only provides height adjustment capabilities, but also has the function of flexible adjustment of wrist and arm angles, which can adapt to the needs of different patients and improve the efficiency and safety of the puncture process. The above settings can significantly improve patient comfort and provide more convenient operating conditions for medical staff.

[0043] In some embodiments, the first telescopic rod 33 includes: a first sleeve 331, a first moving rod 332 and a first motor. The first sleeve 331 is connected to the rotation, and at least a portion of the first moving rod 332 is movably arranged in the first sleeve 331. The end of the first moving rod 332 away from the first sleeve 331 is rotatably connected to the second support plate 35. The first motor is arranged in the first sleeve 331, and the first motor is suitable for driving the first moving rod 332 to move.

[0044] Embodiment 3: Based on embodiment 2, this embodiment has a first rotating portion provided at least at one end of the first support plate 34 in the length direction, and a second rotating portion provided at the second support plate 35 , and the first rotating portion and the second rotating portion are rotatably matched.

[0045] According to some embodiments of the present invention, one of the first rotating portion and the second rotating portion is configured as a rotating hole 351 , and the other of the first rotating portion and the second rotating portion is configured as a rotating rod.

[0046] It is understood that the first rotating portion and the second rotating portion are rotatably engaged to enable the second support plate 35 to rotate relative to the first support plate 34, thereby adjusting the position of the second support plate 35 relative to the first support plate 34. In some embodiments, the first rotating portion can be configured as a rotating hole 351, and the second rotating portion can be configured as a rotating rod, which is rotatably disposed in the rotating hole 351; in other embodiments, the second rotating portion can be configured as a rotating hole 351, and the first rotating portion can be configured as a rotating rod, which is rotatably disposed in the rotating hole 351, without limitation.

[0047] Embodiment 4: Based on the embodiment 2, in this embodiment, the second support plate 35 is constructed as a flexible arc-shaped plate, and the second support plate 35 is gradually bent toward the bottom plate 31 in a direction away from the first support plate 34 .

[0048] It can be understood that the second support plate 35 is made of flexible material (the flexible material can be an aluminum plate, a copper plate or an engineering plastic plate, etc., as long as the second support plate 35 has deformability and reset ability), and is designed as a curved plate, so that the second support plate 35 can better adapt to the natural curve of the patient's arm and provide more comfortable support.

[0049] Specifically, the second support plate 35 starts from one end close to the first support plate 34 and gradually bends toward the base plate 31 in the direction away from the first support plate 34, which helps to guide the patient's arm to be naturally placed on the first support plate 34 and the second support plate 35, ensuring that the wrist is in the best puncture position while the arm is properly supported.

[0050] According to some embodiments of the present invention, a first limiting plate 341 is provided at at least one end of the first support plate 34 in the length direction, and a second limiting plate 352 is provided at one end of the second support plate 35. The free end of the second limiting plate 352 is rotatably connected to the first support plate 34. The first support plate 34 is located above the second support plate 35, and the first support plate 34 is suitable for stopping with the second support plate 35.

[0051] In some embodiments, a first limiting plate 341 is provided at at least one end of the first support plate 34 in the length direction, and the first limiting plate 341 is used to limit the maximum rotation angle of the second support plate 35; a second limiting plate 352 is provided at one end of the second support plate 35, and the free end of the second limiting plate 352 is rotatably connected to the first support plate 34, and the second limiting plate 352 is used to limit the rotation range of the second support plate 35.

[0052] It can be understood that the first support plate 34 is located above the second support plate 35, and the first support plate 34 is suitable for abutting against the second support plate 35, that is, when the second support plate 35 rotates to a certain angle, the first support plate 34 can prevent the second support plate 35 from continuing to rotate, thereby limiting the maximum rotation angle of the second support plate 35.

[0053] It is worth noting that since the second support plate 35 is constructed as a flexible arc-shaped plate, when the first limit plate 341 and the second limit plate 352 stop, if the first telescopic rod 33 continues to drive the second support plate 35 to rotate, at least part of the second support plate 35 will be deformed, so that the shape of the second support plate 35 is closer to a straight plate, so that the second support plate 35 can adapt to more patient groups, thereby improving the applicability of the support pad 1.

[0054] According to some embodiments of the present invention, a flexible cushion is provided on the side of the first support plate 34 and the second support plate 35 facing away from the bottom plate 31. The flexible cushion is usually made of a soft, comfortable and easy-to-clean material, such as medical-grade silicone, foam or other soft materials.

[0055] It is understandable that the flexible padding can increase the comfort of the patient's wrist and arm, and reduce the stress and discomfort caused by maintaining the same posture for a long time; at the same time, it can reduce the pressure of the support board on the wrist and arm, avoid the feeling of oppression, and reduce the risk of obstructed blood circulation; of course, the flexible padding can better fit the patient's wrist and arm, help maintain the stability of the arm position, and reduce movement during the puncture process.

[0056] It is worth mentioning that by adding a flexible pad, skin abrasions or other types of injuries caused by a hard support plate can be reduced, the safety of the puncture process can be improved, and a more comfortable puncture experience can help improve patient satisfaction and reduce patient anxiety and discomfort.

[0057] Preferably, the surface of the flexible pad is also covered with a leather layer, which has a good anti-slip effect on human skin, preventing the patient's arm from sliding relative to the support pad 1. At the same time, the leather layer is easy to clean and disinfect, which facilitates the recycling of the support pad 1.

[0058] Embodiment 5: Based on Embodiment 1, this embodiment includes an adjustment component including: two second telescopic rods 21, the two second telescopic rods 21 are spaced apart along the length direction, the free ends of the two second telescopic rods 21 are respectively rotatably connected to the base plate 31, and the free ends of the second telescopic rods 21 can be selectively moved toward or away from the base 10.

[0059] According to some embodiments of the present invention, the second telescopic rod 21 includes: a second sleeve 211, a second moving rod 212 and a second motor. The second sleeve 211 is connected to the base 10, at least part of the second moving rod 212 is movably arranged in the second sleeve 211, and one end of the second moving rod 212 away from the second sleeve 211 is rotatably connected to the support assembly. The second motor is arranged in the second sleeve 211, and the second motor is suitable for driving the second moving rod 212 to move.

[0060] It can be understood that the two second telescopic rods 21 can control the support assembly to rise or fall when working separately. At the same time, since the free ends of the two telescopic rods are respectively rotatably connected to the base plate 31, the two telescopic rods can be controlled to move differently, that is, the two second movable rods 212 can be controlled to move differently relative to their respective corresponding second sleeves 211, so as to achieve the control of the angle of the support assembly relative to the base 10, so that the support pad 1 can adapt to puncture operations in different situations, thereby improving the adaptability of the support pad 1.

[0061] It is worth noting that a second motor is disposed within the second sleeve 211 and is used to drive the movement of the second movable rod 212. The motor can be an electric motor or other type of drive device to achieve automated height adjustment. Thus, by driving the movement of the second movable rod 212 with the second motor, automated height adjustment of the support pad 1 is achieved, reducing the workload of manual adjustment by medical personnel. Furthermore, motor drive provides more precise adjustment control, ensuring that the wrist and arm are in the optimal puncture position.

[0062] Finally, it should be noted that the above preferred embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail through the above preferred embodiments, those skilled in the art should understand that various changes can be made in form and details without departing from the scope defined by the claims of the present invention.
