In the compressed state, the support mechanism 4 drives the translation mechanism 5 to move downwards, and then the nurse adjusts the translation mechanism 5 according to the child's body shape, and fixes the child's hand in the translation mechanism 5 to prevent it from moving. After the child has finished the drip, the nurse makes the child's arm leave the translation mechanism 5 and hugs the child away from the support mechanism 4. The first spring 3 resets from the compressed state, so that the support mechanism 4 and the translation mechanism 5 return to their original positions. To use the device again, repeat the above steps.

The nurse makes the child sit on the top of the second base plate 43 and makes its back lean against the backrest 44. The gravity of the child makes the second base plate 43 move downwards, and then the backrest 44 and the first support frame 42 are moved downwards. The frame 42 moves down so that the first bottom plate 41 slides downward on the guide rod 2, and the first spring 3 changes from the initial state to the compressed state, thus achieving the purpose of supporting the child. The second bottom plate 43 and the first spring 3 return from the compressed state, and the elastic force makes the second bottom plate 43 and the backrest 44 move back to their original positions.

After the child sits on the second base plate 43, according to the build of the child, the nurse manually moves the third base plate 54 inwardly, and then the first slide block 52 slides inwardly on the first slide rail 51, and the second spring 53 is driven by The initial state changes to a compressed state, and at the same time, the nurse puts the child's hands on the top of the third bottom plate 54 on the left and right sides respectively, and fixes the child's hands, so that it is convenient for the doctor to give the child an IV. The child's hand leaves the third base plate 54 and releases the third base plate 54 at the same time, the second spring 53 resets from the compressed state, and the elastic force makes the first slider 52 and the third base plate 54 move back to their original positions, and then the nurse hugs the child away from the third base plate 54. Two bottom plates 43.

When the third base plate 54 moved inwardly, the third base plate 54 drove the second support frame 61 to move inwardly, and then the first rotating shaft 62 moved inwardly, so that the pressing block 63 moved inwardly. After the top of the third bottom plate 54, the nurse manually turns the briquetting block 63 downwards, and the briquetting block 63 rotates to drive the first rotating shaft 62 to rotate, and then the briquetting block 63 cooperates with the third base plate 54, so that the child's hand is fixed, which can prevent The infusion is affected by the movement of the child’s hands. After the child has finished the drip, the nurse manually reverses the pressing block 63 back to its original position, so that the first rotating shaft 62 reverses back to its original position, and at the same time, the third bottom plate 54 moves back to the outside. original position, so that the pressing block 63 moves outwards and returns to the original position.

When the third bottom plate 54 moves inwardly, the third bottom plate 54 drives the second connecting rod 73 to move inwardly, and then makes the second slide rail 74 move inwardly, so that the first rack 75 and the third spring 78 move inwardly , the movement of the first rack 75 drives the third connecting rod 76 to move inwardly, and then the second wedge block 77 moves inwardly, and the first rotating shaft 62 drives the first gear 79 to move inwardly, and at the same time, the nurse puts the child’s hand on the At the top of the third bottom plate 54, when the second wedge block 77 moves to contact with the first wedge block 72, the first wedge block 72 moves the second wedge block 77 upwards, and then the third connecting rod 76 moves upward, thereby making the first wedge block 77 move upward. A rack 75 slides upwards on the second slide rail 74, and the third spring 78 changes from the initial state to a stretched state, and because the first rack 75 meshes with the first gear 79, the first rack 75 moves up to make the first rack 75 move upwards. A gear 79 rotates, and then the first rotating shaft 62 is rotated, and the first rotating shaft 62 rotates to make the briquetting block 63 rotate downwards, so that the child's hands are fixed, so that the purpose of automatic clamping is achieved. When moving back to the original position, the second wedge block 77 and the first gear 79 are moved back to the original position to the outside, while the second wedge block 77 is separated from the first wedge block 72, and the third spring 78 resets by the stretched state, and the elastic force makes The second wedge block 77 and the first tooth bar 75 move back to the original position downwards, and the first tooth bar 75 moves down to make the first gear 79 reversely turn back to the original position, thereby making the pressure block 63 reversely turn back to the original position, and then The nurse removes the child's hands from the third base plate 54 .

In the initial state, the second base plate 43 cooperates with the telescopic rod 84. When the child sits on the second base plate 43, the nurse opens the air cylinder 82. The operation of the air cylinder 82 makes the connecting block 83 move backward, and then the telescopic rod 84 moves backward. After the second bottom plate 43 is separated from the telescopic rod 84, the nurse manually extends the telescopic rod 84 to limit the position of the child, so as to prevent the child from slipping off the second bottom plate 43 during infusion, and then the nurse closes the cylinder 82 to make the telescopic The rod 84 stops moving. After the child has finished the drip, the nurse restores the telescopic rod 84 to the original length, and then opens the cylinder 82. The operation of the cylinder 82 makes the connecting block 83 and the telescopic rod 84 move back to the original position forward, and the second bottom plate 43 again Cooperate with telescopic rod 84.

When the connecting block 83 moved backward, the connecting block 83 drove the third tooth bar 95 to move backward, and because the third tooth bar 95 meshed with the third gear 94, the third tooth bar 95 moved backward to make the third gear 94 rotate, and then The second rotating shaft 92 is rotated, and the second rotating shaft 92 rotates to drive the second gear 93 to rotate, and because the second gear 93 meshes with the second rack 91, the second gear 93 rotates to move the second rack 91 to the inside, thereby making The first slider 52 moves to the inside, so that the third bottom plate 54 moves to the inside, which can replace the manual push, saving time and effort.
