[0004] In view of the above problems, an innovative design is carried out based on the original remote configuration method of the router and the router. Summary of the invention

[0005] The purpose of the present invention is to provide a limb support device and method for deep vein puncture, so as to solve the problem in the above background technology that although the existing limb support device for deep vein puncture can fix the patient's limb, the setting of the clamping block does not fit the patient's limb, resulting in discomfort to the patient's limb when clamping; and although the limb support device for deep vein puncture can adjust the height, it lacks an angle adjustment mechanism, which makes it inconvenient for doctors to puncture the side of the patient's limb during the puncture process.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a limb support device and method for deep vein puncture, comprising a top plate, a cavity is opened inside the top plate, and a bidirectional screw rod is rotatably connected inside the cavity, a hand crank is connected to the left end of the bidirectional screw rod, and a threaded sleeve is threadedly connected to the outer surface of the bidirectional screw rod, a support plate is fixedly connected to the top of the threaded sleeve, and a clamping block is fixedly connected to one side of the support plate, a threaded rod is threadedly connected to the inner thread of the clamping block, and one end of the threaded rod is connected to the clamping plate through a bearing, and a rubber pad is arranged inside the clamping plate.

[0007] The top plate serves as the top support of the entire structure, and the cavity provides space for the installation and rotation of components such as the bidirectional screw and threaded sleeve. The bidirectional screw is rotated by turning the hand crank, and two threaded sleeves are threadedly connected to the outer surface of the bidirectional screw. The two threaded sleeves move in opposite directions. When the two threaded sleeves move toward the middle at the same time, the limbs can be clamped and fixed. When the two threaded sleeves move toward the outside at the same time, they can be separated from the limbs. The setting of the rubber pad can reduce the squeezing of the patient's limbs, thereby protecting the patient's limbs.

[0008] Preferably, one end of the clamping plate is fixedly connected to a limiting rod, and the limiting rod is slidably connected to the clamping block, a sliding groove is provided at the bottom end of the cavity, and a slider is slidably connected inside the sliding groove, and the slider is fixedly connected to the threaded sleeve.

[0009] By adopting the above technical solution, a clamping plate is used as a part of the clamping mechanism to clamp and fix the patient's limbs. The shape of the clamping plate is designed in an arc shape, which better matches the patient's limbs and can better clamp the patient's limbs. The limit rod is fixedly connected to the clamping plate. By rotating the threaded rod, the clamping plate can be pushed to move. When the clamping plate moves, the limit rod can drive the limit rod to move along the clamping block to ensure stability during the movement process. When the threaded sleeve moves, it can drive the slider to move along the slide groove to ensure that the slider can slide smoothly and remain in the correct position.

[0010] Preferably, a fixing block is fixedly connected to the bottom of the top plate, and a mounting plate is provided below the top plate. The fixing block is hinged to the top plate, and an electric push rod is hinged between the mounting plate and the top plate.

[0011] By adopting the above technical solution, two groups of electric push rods are arranged. When one group of electric push rods pushes the mounting plate to move upward, the other group of electric push rods drives the mounting plate to move downward, so that the angle of the mounting plate can be adjusted.

[0012] Preferably, a fixing frame is provided below the mounting plate, and a rack is slidably connected inside the fixing frame, and the top of the rack is fixedly connected to the mounting plate.

[0013] By adopting the above technical solution, the mounting plate is used as a carrier for the parts that need to be moved or positioned, which is usually used to install and fix other components, provide a mounting and sliding track for the rack, ensure the stability and accuracy of the rack during movement, and the meshing of the gear and the rack. The rack slides along the inside of the fixed frame through the rotation of the gear, thereby driving the movement of the mounting plate, and realizing the precise movement of the rack inside the fixed frame.

[0014] Preferably, the front end of the fixed frame is fixedly connected to a supporting frame, and the interior of the supporting frame is connected to a gear via a rotating shaft. A driving motor is installed on the left side of the supporting frame, and the output end of the driving motor is fixedly connected to the gear.

[0015] By adopting the above technical solution, the fixed frame is used as the fixed part of the entire structure to provide a foundation for the installation and fixation of other components. The support frame is fixedly connected to the fixed frame to support and fix components such as gears and drive motors. After the drive motor is started, the drive motor drives the gears to rotate, which can achieve efficient force transmission and motion conversion, thereby improving the transmission efficiency of the entire system. The rack meshing with the gear can move up and down inside the fixed frame.

[0016] Preferably, a limiting groove is provided inside the support frame, and a limiting block is slidably connected inside the limiting groove, the limiting block is slidably connected to the limiting groove, and the limiting block is fixedly connected to the rack.

[0017] By adopting the above technical solution, a limit groove is opened inside the support frame to guide and limit the moving path of the limit block. The rack is fixedly connected to the limit block, and the limit block realizes its own movement through the movement of the limit block in the limit groove. The rack is slidably connected inside the fixed frame, which can drive the limit block to move along the limit groove to ensure stability during movement.

[0018] Preferably, a base is provided below the support frame, a guide groove is provided on the top of the base, and a guide block is fixedly connected to the bottom of the support frame.

[0020] Preferably, a sliding rod is fixedly connected to the inside of the guide groove, and the guide block is slidably connected to the sliding rod, and an electric telescopic rod is installed between the guide block and the guide groove.

[0021] By adopting the above technical solution, the guide block moves along the slide rod, and by adjusting the extension or shortening of the electric telescopic rod, the guide block can be pushed to move along the guide groove and the slide rod to achieve limited movement, thereby achieving fine adjustment of the position of the guide block.

[0022] Preferably, positioning grooves are provided on both sides of the guide groove, and the interior of the positioning groove is slidably connected to the positioning block, and the positioning block is fixedly connected to the guide block.

[0023] By adopting the above technical solution, the guide groove is used to guide the moving path of the guide block, and the positioning groove provides a sliding track for the positioning block to ensure its stable movement in a specific direction. When the guide block moves along the guide groove, it can drive the positioning block to move along the positioning groove to limit the movement, thereby ensuring the smoothness and stability of the sliding.

[0024] Step 1: First, start the electric telescopic rod, which can drive the guide block to move along the slide bar. When the guide block moves, it can drive the positioning block and the positioning slot to move in a limited manner, so that the guide block drives the support frame and the top support device to move horizontally, ensuring stability during the movement process, thereby facilitating puncture of different parts of the patient; Step 2: Start the drive motor, which can drive the gear to rotate. When the gear rotates, it can drive the rack and the guide block to move up and down along the guide groove. The mounting plate on the top of the rack can drive the support device to move up and down, which can facilitate the height adjustment of the support device. There are two groups of electric push rods. When one group of electric push rods pushes the mounting plate to move upward, the other group of electric push rods drives the mounting plate to move downward, so that the angle of the support device can be adjusted; Step 3: There are two groups of support plates and clamping plates. Start the hand crank, which can drive the bidirectional screw rod to rotate. The threaded sleeve threaded on the outer surface of the bidirectional screw rod can drive the support plate and the clamping block to move. When the threaded sleeve moves, it can drive the slider to move along the slide groove, and the position of the clamping block can be adjusted. Turn the threaded rod again, and the threaded rod can push the clamping plate to move, thereby fixing limbs of different sizes, which is convenient for stability during the puncture process.

[0025] Compared with the prior art, the beneficial effects of the present invention are as follows: the limb support device and method for deep vein puncture, through the provision of a bidirectional screw rod, a hand crank, a threaded sleeve, a support plate, a clamping block, a threaded rod and a clamping plate, by rotating the hand crank, the hand crank can drive the bidirectional screw rod to rotate, and the threaded sleeve threadedly connected to the bidirectional screw rod can drive the support plate, the clamping block and the clamping plate to move, and the patient's limbs can be clamped and fixed, thereby preventing movement during the puncture process.
