[0028] A multifunctional auxiliary device for postoperative rehabilitation of arteriovenous fistula is provided in the utility model, referring to Figs. 1-2 , comprising

[0029] The fixed support base 1 is used for detachable fixing on the guardrail of a sickbed.

[0030] The two surgical side limb support plates 2 are rotatably connected through the first support plate movable shaft 3, and one surgical side limb support plate 2 is detachably pivotally connected with the fixed support base 1 through the second support plate movable shaft 4.

[0031] The several scales 5 are arranged on the surgical side limb support plate and are used for fixing the measurement position of the surgical side limb to measure the swelling degree of the arm circumference.

[0032] The hanging rope 6 is detachably connected with the surgical side limb support plate through the quick connecting buckle at the end of the hanging rope 6.

[0033] When the fixed support base 1 is placed on the sickbed and the patient lies on the sickbed, the surgical side limb is placed on the surgical side limb support plate, and the fixed support base 1 appropriately lifts the surgical side limb support plate 2 to make the limb higher than the heart level, promotes the venous return by using the gravity of the blood itself, reduces the blood and fluid accumulation and swelling caused by surgical trauma, also helps to reduce the activity of the limb, avoids unnecessary pressure or pulling on the surgical site, thereby being beneficial to the healing of the wound and reducing the risk of infection; when the patient is perpendicular to the ground, the second support plate movable shaft 4 can be separated from the fixed support base 1, the hanging rope 6 is hung behind the neck, the support plate movable shaft can change the position of the surgical side limb, and the several scales 5 play the fixing and measuring roles of the surgical side limb when the patient moves.

[0034] Specifically, first, the two surgical limb support plates 2 are connected by rotating the first support plate movable shaft 3, ensuring that the first support plate movable shaft 3 is securely installed, so that the two surgical limb support plates 2 can rotate freely; then, take one surgical limb support plate 2, and detachably pivotally connect one end of the surgical limb support plate 2 to the fixed support base 1 through the second support plate movable shaft 4. During the connection process, the stability of the second support plate movable shaft 4 must be ensured, and the second support plate movable shaft 4 must also be easily detachable. Then, several flexible scales 5 are arranged on the surgical limb support plate 2 and are pasted or fixed according to the pre-designed position, so as to ensure that the scale marks on the surface of the scale 5 are clear and correct, so as to accurately measure the swelling degree of the arm circumference. Finally, the quick connection buckle at the end of the hanging rope 6 is connected to the surgical limb support plate 2. The fixed support base 1 is placed at a suitable position of the hospital bed, so that the fixing clamps of the fixed support base 1 are aligned with the hospital bed guardrails. By operating the fixing clamps, the fixed support base 1 is detachably fixed on the hospital bed guardrails.

[0035] The surface of the surgical limb support plate 2 is provided with a buffer layer made of medical-grade soft material. When the patient lies on the hospital bed, the surgical limb is gently placed on the surgical limb support plate 2. Since the surface of the surgical limb support plate 2 is provided with a buffer layer made of medical-grade soft material, it can provide soft and comfortable support for the surgical limb of the patient, avoiding pressure or discomfort to the limb.

[0036] The length of the hanging rope 6 is adjustable, and the adjustment range is 30cm-60cm. When the patient needs to be perpendicular to the ground (such as sitting up or standing), first, the second support plate movable shaft 4 is detached from the fixed support base 1. Then, the hanging rope 6 is hung behind the patient's neck. Since the length of the hanging rope 6 is adjustable, the adjustment range is 30cm-60cm, and the height and angle of the surgical limb in the hanging state can be adjusted according to the height and body shape of the patient. In this vertical position, the patient can change the body position of the surgical limb through the support plate movable shaft to meet different needs, such as adjusting the stretching degree of the limb. At the same time, the several flexible scales 5 arranged on the surgical limb support plate 2 can continuously measure the swelling degree of the arm circumference. The scale 5 has a scale accuracy of 1mm, which can accurately measure the change of the arm circumference.

[0037] The maximum bearing capacity of the surgical limb support plate 2 is not less than 10kg, which can meet the use requirements of different patients and ensure that there is no safety problem such as damage to the support plate during normal use.

[0038] The bottom of the fixed support base 1 is provided with a non-slip pad. During the fixing process, the non-slip pad (made of rubber material) at the bottom of the fixed support base 1 must be in close contact with the surface of the hospital bed to prevent the device from sliding during use.

[0039] The quick connecting buckle is a clamping hook structure made of plastic material, and the plastic clamping hook structure of the quick connecting buckle is convenient to operate and has certain firmness, and also provides protection for the safety of the device.

[0040] Principle of implementation:

[0041] When the patient lies on the bed, the surgical limb is placed on the surgical limb supporting plate 2, and the fixed support base 1 appropriately raises the surgical limb supporting plate 2 so that the limb is higher than the heart level, promotes venous return by using the gravity of the blood itself, reduces the accumulation of blood and fluid and swelling caused by surgical trauma, and also helps to reduce the activity of the limb, avoids unnecessary pressure or pulling on the surgical site, thereby facilitating wound healing and reducing the risk of infection.

[0042] When the patient is perpendicular to the ground, first disconnect the second supporting plate movable shaft 4 from the fixed support base 1. At this time, the hanging rope 6 begins to play a role, and the quick connecting buckle at the end of the hanging rope 6 is connected with the surgical limb supporting plate 2 and hung behind the neck. The hanging rope 6 can adjust the length and can adapt to patients of different heights and body types. In the vertical position, the patient can use the first supporting plate movable shaft 3 to change the position of the surgical limb. For example, the patient can adjust the first supporting plate movable shaft 3 to bend or stretch the surgical limb within a certain range, and the hanging rope 6 provides additional support force, which cooperates with the first supporting plate movable shaft 3 to ensure that the surgical limb is in the appropriate position and angle, meeting the different needs of the patient in the vertical position.

[0043] The above is only the preferred embodiment of the present application, and does not limit the implementation and protection range of the present application. For those skilled in the art, it should be realized that any equivalent replacement and obvious change obtained by applying the content of the present application specification and drawings should be included in the protection range of the present application.
