[0027] Reference Figure 1 and Figure 4 A pediatric intravenous injection auxiliary positioning structure includes a fixing frame 1, a curved placement groove 2 is opened on the top of the fixing frame 1, a curved top plate 3 is arranged on the top of the fixing frame 1, a fixing mechanism is arranged at the bottom of the fixing frame 1, and a stabilizing component is symmetrically arranged on the outside of the fixing frame 1, and the fixing mechanism and the stabilizing component are used in conjunction with each other.

[0028] The fixing mechanism includes a translation slot 401, which is provided at the bottom of the fixing frame 1. A reciprocating screw rod 402 is rotatably connected inside the translation slot 401. A moving block 403 is threadedly connected to the outer side of the reciprocating screw rod 402. A connecting plate 404 is symmetrically fixedly connected to the outer side of the moving block 403. The tops of the two connecting plates 404 are fixedly connected to support plates 405. A lifting slot 406 is provided on the side where the two support plates 405 are close to each other. A fixing rod 407 is fixedly connected inside the two lifting slots 406. Springs 408 are sleeved on the outer sides of the two fixing rods 407. Lifting blocks 409 are slidably connected to the outer sides of the two fixing rods 407 and located below the springs 408. The two lifting blocks 409 are fixedly connected to the arc-shaped top plate 3. One end of the reciprocating screw rod 402 extends to the outer side of the fixing frame 1 and is fixedly connected to the roller 14.

[0029] The stabilizing component includes a slide groove 5, which is symmetrically opened on the outside of the fixing frame 1. The inside of the two slide grooves 5 is fixedly connected with a slide rod 6, and the outside of the two slide rods 6 is slidably connected with a slider 7. The two sliders 7 are fixedly connected to the two support plates 405 respectively.

[0030] After the child's arm passes through the placement slot 2, the child's arm holds the gripping rod 10, and then the arc top plate 3 is pulled up, and the roller 14 is rotated, and the roller 14 drives the reciprocating screw 402 to rotate, and then the moving block 403 drives the two support plates 405 to move in the direction close to the child, and then the two support plates 405 drive the arc top plate 3 to move in the direction close to the child, until the arc top plate 3 covers the top of the child's arm, at this time, release the hand that pulls the arc top plate 3 upward, and under the tension of the spring 408, press the two lifting blocks 409 downward, thereby driving the arc top plate 3 to follow the lifting blocks 409 to move downward, until the bottom of the arc top plate 3 fits with the top of the child's arm. Through the set fixing mechanism, the child's arm can be fixed during intravenous infusion, avoiding the frequent movement of the child's hand during the infusion process, resulting in the needle deviating from the infusion vein, ensuring the speed and efficiency of the infusion, and at the same time ensuring the safety of the child's infusion.

[0031] For the above example, those skilled in the art should know that when implementing the above technical solution, a sponge or rubber pad can be provided at the bottom of the arc-shaped top plate 3 to ensure flexible contact with the child's arm.

[0032] Reference Figure 1 In a preferred embodiment, a liquid storage tank 12 is provided inside the fixing frame 1, and a water injection hole 13 is provided on one side of the top of the fixing frame 1, and the water injection hole 13 is connected to the liquid storage tank 12. In winter, in order to prevent the liquid medicine from being too cold and causing the child's arm to feel cold, the staff can inject hot water into the liquid storage tank 12 through the water injection hole 13 in advance, which can continuously keep the child's arm warm and improve the comfort of the infusion. At the same time, after adding water to the liquid storage tank 12, the weight of the entire device can be increased, thereby making the device more stable and not easy to be pushed and moved by children.

[0033] For the above example, those skilled in the art should know that when implementing the above technical solution, the water injection hole 13 can also be used for pouring water, that is, used as a drainage hole.

[0034] Reference Figure 1 and Figure 3In a preferred embodiment, a storage rod 8 is symmetrically fixedly connected to one end of the fixing frame 1 away from the roller 14, and a sliding rod 9 is slidably connected to the inside of the two storage rods 8. A gripping rod 10 is fixedly connected to the other end of the two sliding rods 9, and a gripping groove 11 for convenient gripping is provided on the outer side of the gripping rod 10. The storage rod 8 and the sliding rod 9 cooperate with each other, so that the gripping of children with different palm lengths can be adapted, and the palms of children can be supported and protected, so as to avoid long infusion time, resulting in the palms of children being suspended in the air and causing fatigue. Suction cups 15 are symmetrically fixedly connected to both sides of the bottom of the fixing frame 1, and the fixing frame 1 is stably adsorbed on the desktop by the set suction cups 15, so as to avoid the fixing frame 1 being driven by the child's arms to move around, and to fix and limit the child's forearm.

[0035] Working principle: When in use, the staff first places the fixing frame 1 on the desktop, and then presses the fixing frame 1 downward. After being pressed, the fixing frame 1 squeezes the suction cup 15 downward, and the suction cup 15 stably adsorbs the fixing frame 1 on the desktop. Then the staff passes the child's forearm through the placement slot 2, so that the child's arm holds the gripping rod 10, and then pulls the arc-shaped top plate 3 upward, and rotates the roller 14. The roller 14 drives the reciprocating screw rod 402 to rotate, and then the moving block 403 drives the two support plates 405 to move closer to the child, and then the two support plates 405 drive the arc-shaped top plate 3 to move closer to the child. , until the arc-shaped top plate 3 covers the top of the child's forearm, and then the staff releases the hand that is pulling the arc-shaped top plate 3 upward, and under the tension of the spring 408, presses the two lifting blocks 409 downward, so that the arc-shaped top plate 3 follows the lifting blocks 409 to move downward until the bottom of the arc-shaped top plate 3 fits with the top of the child's forearm. In winter, in order to prevent the liquid medicine from being too cold and causing the child's arm to feel cold, the staff can inject hot water into the liquid storage tank 12 through the water injection hole 13 in advance to keep the child's arm warm continuously. At this point, the staff has completed the auxiliary positioning work for intravenous injection in the child's hand.

[0036] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
