[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0024] This embodiment describes a neonatal mechanical ventilation support pad, such as... Figure 1 , Figure 2 and Figure 3 As shown, the device includes a horizontally arranged base plate 1. An adjustment plate 3 is arranged on the upper left side of the base plate 1. The right end of the adjustment plate 3 is hinged to the top of the base plate 1 and can swing up and down. A connecting rod is fixed to the bottom of the right end of the adjustment plate 3. The two ends of the connecting rod extend beyond the adjustment plate 3 and are located on the front and rear sides of the adjustment plate 3. Mounting blocks are fixed to the top of the base plate 1 on the front and rear sides of the adjustment plate 3. The mounting blocks have rotating grooves for the connecting rod to be inserted and rotated freely. By rotating the connecting rod in the rotating grooves, the adjustment plate 3 is hinged to the top of the base plate 1.

[0025] A protective pad 2 is provided on the top of the adjusting plate 3 and the top of the bottom plate 1 on the right side of the adjusting plate 3. The protective pad 2 is a single piece, which can cover the gap at the hinge of the adjusting plate 3 and the bottom plate 1. The protective pad 2 is made of gel material or sponge material and is adhered to the adjusting plate 3.

[0026] The top of the protective pad 2 on the right side of the adjustment plate 3 is provided with a first limiting groove for restricting the newborn's buttocks. The first limiting groove is an arc-shaped groove that fits more closely to the child's buttocks. By restricting the sliding of the child's buttocks through the first limiting groove, the movement of the child's buttocks to the right on the top of the base plate 1 can be reduced, thereby reducing the downward movement of the child's upper body.

[0027] The protective pad 2 above the adjustment plate 3 is provided with a second limiting groove for restricting the upper body of the newborn. The rotation of the upper body of the child is restricted by the second limiting groove. A limiting block 10 is fixed on the top of the protective pad 2 before and after the second limiting groove. The material of the limiting block 10 is the same as that of the protective pad 2. The limiting block 10 can increase the restriction on the rotation of the upper body of the child. When the child's limb movement is not large, the first restraint belt 11 is not needed to restrain the child's limbs.

[0028] A third limiting groove is provided on the protective pad 2 on the left side of the second limiting groove to restrict the head of the newborn. The third limiting groove is also an arc-shaped groove that fits the head of the child and restricts the rotation of the child's head through the third groove.

[0029] The protective pad 2 has a fabric layer 14 on top, which fits into the first limiting groove, the second limiting groove, and the third limiting groove. The fabric layer 14 prevents the child from directly contacting the protective pad 2. The softness of the fabric layer 14 reduces the child's discomfort. The fabric layer 14 covers the protective pad 2, making it easy to replace.

[0030] The adjustment plate 3 is equipped with a first restraint strap 11 for restraining the upper body of the newborn, and the base plate 1 is equipped with a second restraint strap 13 for restraining the lower body of the newborn.

[0031] The adjusting plate 3 has first sliding blocks 17 on both its front and rear sides, which slide along its length. Second sliding grooves are also provided on both sides of the adjusting plate 3. These second sliding grooves engage with the first sliding blocks 17 in a "T" shape to prevent the first sliding blocks 17 from disengaging from the grooves. A first bolt is provided on the handle 7 to restrict the sliding of the first sliding blocks 17 on the adjusting plate 3. A first constraint band 11 is connected to the first sliding blocks 17, and its position is adjusted by the sliding of the first sliding blocks 17, allowing the first constraint band 11 to... To restrain different parts of the upper body of the child; the front and rear sides of the base plate 1 are provided with second sliding blocks 18 that slide along their length direction, and the front and rear sides of the base plate 1 are also provided with third sliding grooves. The third sliding grooves and the second sliding blocks 18 are in a "T" shape sliding fit to prevent the second sliding blocks 18 from disengaging from the third sliding grooves. The second sliding blocks 18 are provided with second bolts, and the second restraint belt 13 is connected to the second sliding block 18. The position of the second restraint belt 13 is adjusted so that the second restraint belt 13 restrains different parts of the lower body of the child.

[0032] A movable block 4 is provided on the top left side of the base plate 1, which slides left and right with it. A first slider 12 is provided on the bottom of the adjusting plate 3, which slides along its length. A fourth groove is provided on the bottom of the adjusting plate 3 for the first slider 12 to be inserted and slide along its length. The first slider 12 slides within the fourth groove, preventing it from moving back and forth at the bottom of the adjusting plate 3. The bottom of the first slider 12 is hinged to the top right side of the movable block 4 and swings left and right. The top right side of the movable block 4 is hinged to the middle of the first slider 12. Through the hinge between the first slider 12 and the movable block 4, when the movable block 4 slides left and right and the tilt angle of the adjusting plate 3 changes, the angle of the first slider 12 also changes with the adjusting plate 3, causing the first slider 12 to... A slider 12 is attached to the bottom of the adjusting plate 3. Alternatively, the first slider 12 and the fourth groove at the bottom of the adjusting plate 3 can be in a "T"-shaped sliding fit. A roller is installed on the top of the first slider 12, which rolls in the fourth groove to reduce friction between the first slider 12 and the third groove, facilitating the movement of the movable block 4 in moving the first slider 12 within the fourth groove. The movement of the movable block 4 changes the actuation point of the movable block 4 on the adjusting plate 3, thereby adjusting the tilt angle of the adjusting plate 3. In some embodiments, the first slider 12 can be omitted, and a roller can be installed on the top right side of the movable block 4, so that the roller contacts the bottom of the adjusting plate 3. The horizontal movement of the transition block 4 pushes the adjusting plate 3, changing the tilt angle of the adjusting plate 3. This section constitutes an adjusting mechanism for adjusting the tilt angle of the adjusting plate 3.

[0033] In some embodiments, the adjustment mechanism may further include an adjustment rod with a sleeve fitted on it and a bolt on the sleeve. The adjustment rod is hinged to the top of the base plate 1, and the sleeve is hinged to the bottom of the adjustment plate 3. The tilt angle of the adjustment plate 3 can be adjusted by changing the combined length of the sleeve and the adjustment rod.

[0034] To facilitate operation of the movable block 4, a fixing block 5 is vertically fixed to the top of the base plate 1 on the left side of the movable block 4. The fixing block 5 has a threaded hole that is open to the left and right. A screw 6 that is threadedly engaged with the screw 6 is installed in the threaded hole. A handle 7 is provided at the left end of the screw 6, which makes it easy to rotate the screw 6.

[0035] A fixing rod 8 is fixed to the end of the screw 6, and a fixing tube 9 is fitted onto the fixing rod 8. The fixing tube 9 is fixed to the movable block 4. A bearing is installed between the fixing rod 8 and the fixing tube 9, connecting them. The fixing rod 8 can rotate freely. When the screw 6 rotates, it will not cause the movable block 4 to rotate. The rotation of the screw 6 changes the position of its end, thereby moving the movable block 4. The tilt angle of the adjusting plate 3 can be adjusted by rotating the screw 6 alone, which is convenient. Alternatively, the fixing tube 9 can be omitted. The movable block 4 has a mounting groove for inserting the fixing rod 8. The mounting groove is circular, and a bearing is installed between the fixing rod 8 and the mounting groove, allowing the fixing rod 8 to rotate independently. This section constitutes a connecting assembly for connecting the screw 6 and the movable block 4 and allowing the screw 6 to rotate independently.

[0036] In some embodiments, the screw 6 can be replaced with a smooth rod, which is directly fixed to the movable block 4. The threaded hole on the fixed block 5 is a through hole, and the fixed block 5 is provided with a bolt to fix the rod in the through hole. The rod is fixed in the through hole by the bolt, and the movement of the rod in the through hole drives the movable block 4 to move.

[0037] To reduce friction between the fixed block 4 and the base plate 1, the top of the base plate 1 is provided with a first groove for the bottom end of the movable block 4 to be inserted and slide left and right. The bottom of the movable block 4 is fixed with a second slider 16. The second slider 16 and the first groove are in a "T" shape to prevent the movable block 4 from disengaging from the first groove. The bottom of the movable block 4 is equipped with a roller 15 that rolls left and right in the first groove. The roller 15 is a directional roller that rolls left and right. The roller 15 can reduce the friction between the first slider 12 and the first groove, so that the left and right movement of the movable block 4 is smoother.

[0038] The working principle and technical effects of this embodiment:

[0039] During use, place the child on top of the protective pad 2, with the child's upper body positioned on the protective pad 2 at the top of the adjusting plate 3. By tilting the adjusting plate 3, the child's upper body and head can be raised. Depending on the child's condition and feedback during treatment, the movable block 4 can be slid left or right by rotating the screw 6, causing the movable block 4 to push the adjusting plate 3 to the right or move the movable block 4 to the left, causing the left end of the adjusting plate 3 to move downward, thus changing the tilt angle of the adjusting plate 3 and adjusting the angle at which the child's upper body and head are raised. The positions of the first restraint strap 11 and the second restraint strap 13 can be adjusted by sliding the first sliding block 17 along the length of the adjusting plate 3 and the second sliding block 18 along the length of the base plate 1, thus restraining the child's limb movements. Of course, during use, depending on the child's limb movement, the first restraint strap 11 and the second restraint strap 13 should be avoided from being used simultaneously to restrain the child's upper and lower limbs to prevent over-restraint.
