[0002] When giving intravenous injections to children, the infusion is troublesome because the children are very active. To avoid this phenomenon, medical staff usually use tape to tie the children's hands and feet to the paper medicine box one circle after another. However, although this method can work, the operation is too cumbersome, and more tape is needed for one injection, and it may also cause skin allergies. To solve this problem, a pediatric hand and foot intravenous injection care device has been developed, including a fixing plate, an elastic band, a groove and other parts. However, this device has a flat structure and is only suitable for intravenous injections in the hands. It is difficult to fix the feet. In addition, although the hands can be fixed, the device itself is not fixed, and there are still risks during operation.

When the screw handle 13 is rotated, the pressure plate 14 moves forward, and the locking tooth 15 is engaged with the locking tooth groove 10 to achieve the fixing of the angle between the short support plate 2 and the long support plate 3. The spring 8 is sleeved on the rear end of the hinge rod 5 and is located in the spring groove 7 to provide reverse elastic force. When the screw handle 13 is reversely twisted, the spring 8 pushes the pressure plate 14 open, and the locking tooth 15 is separated from the locking tooth groove 10. The guide rod 16 is slidably installed in the guide rod hole 17 to ensure the smooth movement of the pressure plate 14 and limit its rotation.

[0037] A pair of strap grooves 18 are provided on the long support plate 3 and the short support plate 2, and the strap 4 is fixed in the strap groove 18 by a pair of locking screws 23. The locking screw 23 passes through the lower bolt hole 19 and the upper bolt hole 22 of the strap 4, and is threadedly connected with the square nut 21. The square nut 21 is slidably installed in the nut groove 20, which is convenient for adjusting the position of the strap 4. By adjusting the position of the pair of locking screws 23, the strap 4 can better adapt to the width of the child's hands and feet, and better fix them to prevent the hands and feet from moving. The end of the strap 4 is tightened by Velcro, and the tightness can be flexibly adjusted according to the size of the child's hands and feet, ensuring the fixation effect while avoiding skin compression.

[0038] The upper surfaces of the long support plate 3 and the short support plate 2 are covered with a silicone layer, and all edges are provided with arc chamfers to avoid damage to the skin of the child. The strap 4 is made of soft material, and the end is tightened by Velcro, which is easy to operate and comfortable.

[0039] Through the flexible adjustment of the long support plate 3 and the short support plate 2, the device is not only suitable for intravenous injection in the hand, but also can fix the foot by adjusting the angle, solving the problem that the existing planar structure device cannot fix the foot.

The hinge ball heads 30 at the upper and lower ends of the telescopic rod 26 are respectively ball-hinged on the upper ball joint seat 25 and the lower ball joint seat 27, and locking mechanisms are provided between the upper ball joint seat 25 and the lower ball joint seat 27 and the hinge ball head 30. A mounting seat 28 is also provided at the bottom of the lower ball joint seat 27, and the upper ball joint seat 25 is fixedly connected to the bottom of the long support plate 3.

[0041] A hemispherical groove 29 is provided on the upper ball joint seat 25 and the lower ball joint seat 27, and a ball pressing sleeve 32 is threadedly connected to the upper ball joint seat 25 and the lower ball joint seat 27. The inner wall of the ball pressing sleeve 32 is a contoured surface 31, and a hand-tightened ridge is provided on the circumferential outer wall of the ball pressing sleeve 32. The articulated ball head 30 is located in the hemispherical groove 29 and the contoured surface 31.

[0042] Working principle in this embodiment:

[0043] In this embodiment, the support mechanism 24 includes an upper ball joint seat 25, a lower ball joint seat 27 and a telescopic rod 26. Both ends of the telescopic rod 26 are provided with articulated ball heads 30, which are respectively ball-jointed with the upper ball joint seat 25 and the lower ball joint seat 27. The upper ball joint seat 25 is fixed to the bottom of the long support plate 3, and the bottom of the lower ball joint seat 27 is provided with a mounting seat 28 for fixing the device on a bed, a chair or a desktop. By adjusting the length of the telescopic rod 26 and the angle of the articulated ball head 30, the height and inclination angle of the long support plate 3 and the short support plate 2 can be adjusted to meet the body position requirements of different children. The ball pressing sleeve 32 is threadedly connected to the upper ball joint seat 25 and the lower ball joint seat 27, and is used to lock the articulated ball head 30 to ensure the stability of the support mechanism 24.
