[0027] Figure 1 This is a structural schematic diagram of a neck braking and pressure-reducing pillow according to the present invention.

[0028] In the attached diagram, 100 is the hollow pillow body; 200 is the medical foam dressing; and 300 is the fixing block. Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0030] Reference Figure 1 The neck braking and pressure-reducing pillow shown includes:

[0031] Hollow pillow body 100: It has a U-shaped structure and is composed of a rigid support layer and a flexible contact layer. The U-shaped opening end corresponds to the back of the human neck.

[0032] It should be noted that the hollow pillow body 100 has an overall U-shaped design, with the open end extending forward to the back of the neck and the closed end wrapping around the pillow area.

[0033] Rigid support layer: Made of polypropylene (PP) through injection molding, with an internal honeycomb structure (honeycomb pore size 5-10mm) to reduce overall weight while ensuring support strength (approximately 30% lighter than traditional rigid materials).

[0034] Flexible contact layer: Covering the upper surface of the rigid support layer, it is made of 3-5cm thick slow rebound memory foam, and the surface is seamlessly wrapped with medical-grade skin-friendly fabric to conform to the curves of the human neck and occipital region.

[0035] This design effectively combines rigid support with flexible cushioning: the U-shaped rigid support layer provides stable neck immobilization, restricting excessive neck movement, and is suitable for postoperative fixation;

[0036] The memory foam flexible contact layer disperses neck pressure, avoiding skin damage caused by direct pressure from hard materials.

[0037] Lightweight design: The honeycomb structure reduces the amount of material used, lowering the pillow's weight (approximately 1.2-1.5 kg), making it easier to move and adjust the patient's position.

[0038] Concave filling part: It is embedded in the center of the U-shaped concave area of ​​the hollow pillow body 100, and a medical foam dressing 200 is provided on its top. The surface contour of the concave filling part is adapted to the shape of the human pillow.

[0039] In this embodiment, it should be noted that the concave filling part is embedded in the geometric center of the 100U-shaped concave area of ​​the hollow pillow body, and the axis of symmetry coincides with the axis of the human cervical spine.

[0040] Surface profile: The top is a concave arc surface (radius of curvature R = 80-120mm), which is adapted to the bony structure of the human occipital region; the four edges are transitioned to a flexible contact layer through gradient density sponge (density decreases from the inside to the outside), with a thickness of 2-4cm.

[0041] Top Medical Foam Dressing 200: Rectangular medical foam dressing 200 (size 20cm×15cm×2cm) can be detached and installed with Velcro. The surface layer is medical silicone or polyurethane antibacterial and skin-friendly layer, and the bottom layer is open-cell breathable foam.

[0042] This design enables precise pressure distribution: the concave curved surface conforms to the pillow, avoiding localized pressure concentration and reducing the risk of pressure sores; the gradient density sponge allows pressure to be transmitted in a decreasing manner from the center to the periphery, reducing soft tissue compression.

[0043] Integrated medical functions: Antibacterial dressings inhibit bacterial growth and are suitable for postoperative wound care; the breathable foam layer accelerates sweat evaporation and improves comfort during long-term bed rest.

[0044] A connecting slot is provided at the bottom of the concave filling part; it should be noted that the connecting slot is located at the bottom of the concave filling part. A trapezoidal groove (groove depth 1-2cm, groove width 3-4cm) is provided at the bottom of the concave filling part, and a silicone anti-slip strip (thickness 2mm, Shore hardness 40A) is embedded in the inner wall of the groove, and a limiting protrusion is provided at the bottom of the groove.

[0045] This design provides excellent mechanical locking and anti-dislodgement: the trapezoidal groove and the inclined surface of the fixing block 300 cooperate to form a self-locking structure, preventing lateral displacement of the concave filling part; the silicone anti-slip strip increases the coefficient of friction, avoiding accidental loosening under vibration or external impact. Quick positioning and installation: the trapezoidal guide design facilitates automatic alignment when the block is inserted, reducing assembly difficulty.

[0046] Detachable connection structure: includes a fixing block 300, which is trapezoidal; the fixing blocks 300 are symmetrically distributed on both sides of the U-shaped opening end, and are used to fix the concave filling part.

[0047] It should be noted that the fixing block 300 is a trapezoidal rigid plastic block (polypropylene material, size 4cm×2cm×1.5cm) symmetrically distributed on both sides of the U-shaped opening end. The inner bevel matches the trapezoidal groove of the connecting slot, and the bottom is fixed to the rigid support layer by screws.

[0048] Velcro assembly: The male patch (5cm x 5cm) is sewn onto the bottom surface of the medical foam dressing 200, and the female patch (8cm x 8cm) is bonded to the top surface of the concave filling part. Quick positioning is achieved through staggered coverage.

[0049] The advantages of this design are: Modular and detachable design: The fixing block 300 cooperates with the connecting slot to achieve quick assembly and disassembly of the concave filling part, facilitating the replacement of filling modules of different thicknesses or functions; the Velcro assembly supports single-person, one-handed replacement of medical dressings, avoiding the risk of contamination. Optimized adaptability: Symmetrically distributed blocks ensure uniform force distribution on the concave filling part, adapting to patients with different head circumferences (compatible with neck circumferences of 28-40cm); the trapezoidal snap-fit ​​structure allows for fine-tuning of the filling part height (±5mm), meeting individualized treatment needs.

[0050] In some specific embodiments, the rigid support layer is integrally molded from polypropylene and has a honeycomb-shaped weight-reduction structure inside;

[0051] The flexible contact layer is made of memory foam and is 3-5cm thick, seamlessly covering the upper surface of the rigid support layer.

[0052] In some specific embodiments, the concave filling part is located at the geometric center of the hollow pillow body 100, its axis of symmetry is aligned with the axis of the human cervical spine, its thickness is 2-4cm, and its four edges are connected to the flexible contact layer through gradient density sponge.

[0053] In some specific embodiments, the surface of the medical foam dressing 200 is an antibacterial and skin-friendly layer made of medical silicone or polyurethane.

[0054] In some specific embodiments, the connecting slot is a trapezoidal groove with embedded silicone anti-slip strips. The depth of the slot is 1-2cm, forming a mechanical limiting fit with the fixing block 300.

[0055] In some specific embodiments, it also includes: a hook and loop fastener assembly;

[0056] The Velcro assembly includes a male and a female patch, which are respectively fixed to the mating surfaces of the bottom and the concave filling part of the medical foam dressing 200. The male patch covers a smaller area than the female patch to enable quick positioning and removal.

[0057] In some specific embodiments, the pressure-reducing foam dressing is rectangular.
