[0019] In the description of the embodiments of the present invention, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in the present invention according to the specific circumstances. Example

[0020] This embodiment provides a neonatal PICC placement operating table, which mainly consists of a base 1, a support column 2, a tilting locking mechanism 3, an operating platform body 4, an infant lying tray assembly, an upper limb abduction fixation assembly 9, a heat storage and insulation assembly, and a protective baffle assembly.

[0021] The base 1 is a rectangular metal frame with anti-slip pads 11 installed at each of its four corners to improve stability. The support column 2 is vertically welded to the center of the upper surface of the base 1. A tilting locking mechanism 3 connects the support column 2 to the operating platform body 4 and allows for angle adjustment of the operating platform. Specifically, a U-shaped hinge seat 31 is fixed to the top of the support column 2, and two downward-extending connecting ear plates 32 are fixed to the corresponding positions on the bottom surface of the operating platform body 4. The two connecting ear plates 32 are inserted into the U-shaped hinge seat 31 and hinged together by a horizontal pivot 33. Loosening the locking bolt 34 allows the operating platform body 4 to tilt forward or backward to achieve a head-up, feet-down or horizontal position; tightening the locking bolt 34 locks the operating platform body 4 at the desired angle.

[0022] The main body of the operating platform 4 is a rectangular double-layer structure, including an upper rigid support plate 41 and a lower heat-insulating cavity shell 42. The support plate 41 is made of aluminum alloy sheet with good thermal conductivity. A removable silicone pad is laid on the upper surface of the support plate 41. The center of the pad 5 has an integrally formed arc-shaped recess that matches the curvature of the newborn's torso, forming the infant trough 5. A movable headrest 6 is placed at the head end of the trough 5. The lower surface of the headrest 6 is detachably attached to the upper surface of the pad 5 with Velcro, making it easy to adjust the position of the headrest according to the actual length of the newborn. Torso restraint straps 7 are sewn on both sides of the middle section of the trough 5. The ends of the torso restraint straps 7 can be opened and closed with buckles or Velcro, used to gently fix the newborn's torso and prevent it from shifting significantly during operation.

[0023] The main body 4 of the operating platform has a longitudinally extending elongated adjustment hole 8 on each side edge near the middle section of the slot 5. Each adjustment hole 8 has an upper limb abduction fixation component 9 installed at it. The cross-section of the adjustment hole 8 is inverted T-shaped. The upper limb abduction fixation component 9 includes a sliding seat 91, a vertical screw 92, a locking knob 93, a rotating arm 94, a palm support 97, and a restraint strap 96. The sliding seat 91 is located below the adjustment hole 8, and a vertical screw 92 is fixed to the sliding seat 91. The vertical screw 92 passes upward through the adjustment hole 8, and a locking knob 93 is fitted at its protruding end. The locking knob 93 is threadedly engaged with the vertical screw 92. When loosened, the sliding seat 91 can slide longitudinally along the adjustment hole 8 to the desired position. When tightened, the lower end of the locking knob 93 presses against the upper surface of the main body 4 of the operating platform, thus positioning the sliding seat 91. One end of the rotating arm 94 has an annular sleeve 941, which is fitted onto the top of the vertical screw 92. The rotating arm 94 forms a horizontally rotatable joint with the top of the vertical screw 92 via a horizontal locking nut 95. Tightening the horizontal locking nut 95 locks the rotating arm 94 at the desired rotation angle. The other end of the rotating arm 94 is connected to a palm support 97 via a short vertical shaft. The palm support 97 is an arc-shaped concave plate used to support the newborn's palm and wrist. Flexible restraint straps 96 are fixed on both sides of the groove of the palm support 97 to fix the hand and forearm and prevent limb retraction during puncture.

[0024] The heat storage and insulation component is integrated into the lower layer of the main body 4 of the operating platform. A drawer-type opening 44 is provided on one side of the insulation chamber shell 42, inside which an insulation chamber drawer 43 slides. The insulation chamber drawer 43 is used to hold a flat hot water storage bag made of medical-grade PVC material, which has a water inlet and a matching sealing cap. In use, approximately 40°C warm water is injected into the hot water storage bag through the water inlet and sealed. It is then placed into the insulation chamber drawer 43 and pushed into the flat cavity.

[0025] When using this operating table clinically, depending on the puncture site and the child's condition, loosen the locking bolt 34, adjust the main body 4 of the operating platform to the required tilt angle, and then tighten and lock it. Take out the insulated drawer 43, put in a hot water bag filled with warm water and sealed, push it back in, and lock it with the elastic buckle. Move the headrest 6 to a suitable position, place the newborn supine in the lying groove 5, and lightly tie the torso with the torso restraint strap 7. After selecting the upper limb on the puncture side, first loosen the locking knob 93 of the corresponding upper limb support assembly, slide the sliding seat 91 longitudinally along the adjustment hole 8 to a position that adapts to the child's shoulder, and then tighten it; then loosen the hand-tightening nut, rotate the rotating arm 94 horizontally to abduct the upper limb to the required puncture angle, and then tighten the hand-tightening nut; finally, gently fix the hand and wrist with the restraint strap 96. After the operation, release the restraints in sequence, take out the hot water bag, and remove the silicone pad, headrest 6, and other detachable parts for cleaning and disinfection for future use.

[0026] The present invention and its embodiments have been described above. This description is not restrictive, and the accompanying drawings are only one embodiment of the present invention; the actual structure is not limited thereto. In conclusion, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the spirit of the invention, such designs should fall within the protection scope of the present invention.
