DETAILED DESCRIPTION

[0018] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0019] The present application embodiment discloses an arm fixing device for children's infusion, referring to Figure 1 , including a base 1 and a movable seat 2, the base 1 is used to be fixedly connected to the armrest of the seat, specifically, it can be fixedly connected to the armrest of the seat by bolts, or it can be directly fixed to the armrest of the seat by welding. The movable seat 2 is movably hinged on the top of the base 1, and the base 1 limits the rotation of the movable seat 2 by a first limiter. Two positioning blocks are protrudingly arranged on the top wall of the movable seat 2 at intervals, and a first mounting groove 21 adapted to the arm and a second mounting groove 22 for accommodating the palm are respectively provided on the two positioning blocks. On the same side of the first mounting groove 21 and the second mounting groove 22 on the movable seat 2, a first positioning cover 23 and a second positioning cover 24 are also hingedly installed, the first positioning cover 23 and the first mounting groove 21 cooperate to form a first positioning cavity for wrapping the arm, and the second positioning cover 24 and the second mounting groove 22 cooperate to form a second positioning cavity for wrapping the palm, and a second limiter for limiting the movement of the first positioning cover 23 and the second positioning cover 24 is provided on the movable seat 2.

[0020] In the embodiment of the present application, the first limiting member is a first limiting bolt 11. Specifically, a spherical ball joint 25 is integrally fixedly connected to the bottom of the movable seat 2, and a ball joint groove 12 adapted to the ball joint 25 is provided on the top of the base 1, and the ball joint 25 is movably hinged in the ball joint groove 12. A first screw hole 13 connected to the ball joint groove 12 is provided on the side wall of the base 1, and the first limiting bolt 11 is threadedly connected in the first screw hole 13. By screwing the first limiting bolt 11, the first limiting bolt 11 is pressed against the ball joint 25, so that the ball joint 25 and the movable seat 2 can be fixed. In order to further improve the stabilization effect of the movable seat 2, an anti-slip rubber pad can also be provided at the end of the first limiting bolt 11 to enhance the friction between the ball joint 25 and the ball joint 25.

[0021] In other embodiments, the first limiting member can also be an eccentric handle, which is formed by penetrating the side wall of the ball joint groove 12 on the base 1 to open an expansion and contraction opening, and fixing connecting plates on the outer wall of the base 1 on both sides of the expansion and contraction opening. A pull rod is fixedly connected to one connecting plate, and the pull rod is movably arranged on another connecting plate. The eccentric handle is hingedly connected to the end of the pull rod away from the connecting plate, and the outer wall of the eccentric handle gradually expands outward from the hinge axis. An anti-slip pad is provided between the eccentric handle and the connecting plate. By rotating the eccentric handle, the pull rod is pulled, and the two connecting plates are brought closer to each other, thereby clamping the ball joint 25.

[0022] The second limiting member can be an elastic band 3, and the elastic band 3 is specifically provided with two elastic bands 3, and the two elastic bands 3 correspond to the first positioning cover 23 and the second positioning cover 24 respectively. One end of the elastic band 3 is fixedly connected to the edge on the same side of the first mounting groove 21 and the second mounting groove 22 on the movable seat 2, and a connecting buckle 31 is provided on the other side edge of the movable seat 2 away from the elastic band 3, and a hook 32 is connected to the movable end of the elastic band 3, and the hook 32 can be matched with the connecting buckle 31. After the first positioning cover 23 and the second positioning cover 24 are rotated and covered on the top of the first mounting groove 21 and the second mounting groove 22, the elastic band 3 is stretched, so that the elastic band 3 passes over the top of the first positioning cover 23 and the second positioning cover 24 and is movably buckled with the connecting buckle 31, so that the first positioning cover 23 and the second positioning cover 24 can be pressed and fixed on the movable seat 2. In other embodiments, the movable ends of the first positioning cover 23 and the second positioning cover 24 can also be fixed on the movable seat 2 by using a second limiting bolt.

[0023] In the embodiment of the present application, the movable end of the second positioning cover 24 is provided with a clearance opening 241 for the infusion tube to pass through. After the infusion tube is connected to the child's arm, the child's arm is placed in the first mounting groove 21 and the second mounting groove 22 on the movable seat 2, and the first positioning cover 23 and the second positioning cover 24 are covered so that the infusion tube extends from the clearance buckle on the second positioning cover 24, and the first positioning cover 23 and the second positioning cover 24 are fixed. The child moves his arm and drives the movable seat 2 to rotate on the base 1. After finding the most suitable support angle, the operator tightens the first limit bolt 11 to limit the rotation of the base 1. Through the above design, the operator can flexibly choose whether to fix and limit the movable seat 2, so that the child's arm can loosen the movable angle of the movable seat 2 when it feels sore, thereby improving the comfort of the child during the infusion process.

[0024] Furthermore, a flexible bushing 4 is fixedly provided on the inner wall of the first installation groove 21 and the first positioning cover 23. The flexible bushing 4 can be filled with sponge, silica gel or cotton, so that when the child's inner wall is placed in the first installation groove 21, the flexible bushing 4 contacts the arm skin and plays a buffering and flexible supporting role on the arm, thereby improving the comfort of infusion.

[0025] Reference Figure 2Furthermore, a hemispherical movable cavity can be formed in the second mounting groove 22. The second mounting groove 22 is composed of a front part and a rear part. The front part is used to support the wrist, and the rear part is used to accommodate the palm. The front part and the second positioning cover 24 form a cylindrical shape, and the rear part and the second positioning cover 24 form a spherical shape. A movable plate 5 is rotatably arranged in the second mounting groove 22. The movable plate 5 is adapted to the rear part of the second mounting groove 22 and is in a hemispherical shape with an upper opening. A gripping rod 51 is arranged in the upper opening of the movable plate 5 along the width direction of the second mounting groove 22. Specifically, a sliding groove is opened on the bottom wall of the movable cavity of the second mounting groove 22 along the circumference of the front part of the second mounting groove 22. A slider is fixed on the bottom wall of the movable plate 5. The slider is movably embedded in the sliding groove so that the movable plate 5 can slide along the sliding groove.

[0026] By providing the movable cavity, the child's palm can be clenched and stretched freely in the movable cavity. By providing the holding rod 51, the child can hold the holding rod 51 in the movable cavity to position the arm, and the holding rod 51 plays a supporting role for the palm in the movable cavity. The child can also hold the holding rod 51 in the movable cavity to get a sense of security. At the same time, by flexibly rotating the movable plate 5 in the movable cavity relative to the second mounting groove 22, the child can also move the palm when holding the holding rod 51, thereby improving comfort.

[0027] Furthermore, a handle 52 is coaxially rotatably provided on the gripping rod 51. When a child holds the gripping rod 51, the child can flexibly rotate the handle 52 to avoid forcibly twisting the gripping rod 51 and causing damage to the gripping rod 51.
