Description

Technical Field

[0001] This utility model relates to the technical field of seat cushion products, specifically to a portable orthopedic seat cushion. Background Technology

[0002] Existing general-purpose seat cushions, especially foam cushions, such as the one in patent CN203987111U, have protrusions. When a person sits on them, the weight of the body causes the buttocks to sink deeply into the cushion, creating a protrusion in the middle that compresses and closely contacts the prostate. Over time, this can easily lead to prostatitis or benign prostatic hyperplasia (BPH). If BPH is already present, sitting on the cushion will be even more uncomfortable. To address this, some existing seat cushion products create cavities in the area relative to the perineum, such as the "Ω"-shaped cavity in patent CN205144074U, to avoid the perineum and provide some pressure relief. However, with prolonged use, because there is no effective ventilation gap between the pelvic organs and the cushion to prevent the pelvic organs from contacting the cushion (e.g., the surface, the bottom of the recess), moisture and heat accumulate, causing significant discomfort. Furthermore, because existing seat cushion products lack targeted weight distribution, they increase pressure on the lumbar and sacral spine, potentially inducing or exacerbating prostatitis and hemorrhoids.

[0003] Although some prostate protection cushions have adopted a groove design, such as patent CN204048808U which uses two independent sponges to form a rectangular groove, although this can distribute pressure and suspend the perineal organs, the right-angled edges will cause stress concentration and structural deformation under load. This is not conducive to maintaining the stability of the cushion structure and extending the life of the cushion. Its air channel is prone to collapse and deformation under load, and it cannot fix the user's body in the middle of the air channel, causing the user to have poor sitting posture and negatively affecting the spine.

[0004] Therefore, there is an urgent need for a portable orthotic cushion with better ventilation, cushioning, and ergonomic support to reduce pressure on pelvic organs, alleviate spinal load, and improve ventilation. Utility Model Content

[0005] This utility model aims to at least partially solve one of the technical problems existing in the aforementioned product technology. To this end, this utility model proposes a portable orthopedic cushion having a recess 3 for pressure relief and ventilation (see...). Figure 2-3 By optimizing the concave structure to achieve pressure relief and ventilation, it can provide ergonomic support, reduce pressure on pelvic organs, reduce spinal load, and improve ventilation of pelvic organs.

[0006] To achieve the above objectives, the following technical solution is provided in some embodiments of this utility model: a portable orthopedic cushion, comprising a main body, the main body including an elastic base 1 (see...). Figure 1-2 , Figure 4-5 ) and upper surface 2 (see Figure 1-2 The upper surface 2 includes a support area 22 (see...). Figure 1-2 The support area 22 includes a left support area and a right support area; wherein, the elastic base 1 has a recess 3 extending through its width in the middle, and the recess 3 forms a longitudinal air channel extending through the middle of the elastic base (see...). Figure 1-3 The air channel design aims to completely avoid physical contact between the cushion surface and the pelvic organs or spine; when in use, the longitudinal air channel forms an effective ventilation gap that prevents the pelvic organs from contacting the bottom of the recess 3; the sidewall 31 of the recess 3 (see...) Figure 1-2 The upper surface 2 and the supporting area 22 are connected by a smooth first rounded corner transition section 32 (see [link]). Figure 1-2 It forms a continuous arc-shaped contour, which can reduce damage to the soft tissues of the ischium and reduce the load on the spine when used by the user.

[0007] According to some embodiments of this utility model, the width k of the recess 3 is 6-10cm, the depth d is 5-7cm, and the length of the recess 3 is slightly less than or equal to the width of the elastic base; the air channel is an end-to-end through structure to ensure air circulation.

[0008] According to some embodiments of the present invention, the bottom 33 of the recess 3 is provided with a smooth second rounded corner transition section 34. The radius of curvature of the second rounded corner transition section 34 is 4-8cm. The second rounded corner transition section 34 can achieve smooth transition and load buffering, while maintaining the structural integrity and durability of the bottom 33 of the recess 3.

[0009] According to some embodiments of the present invention, the cross-section of the recess 3 is U-shaped or semi-circular to adapt to the user's body structure, reduce edge stress and prevent bottom breakage, thereby extending the service life of the portable orthopedic cushion.

[0010] According to some embodiments of this utility model, the radius of curvature of the first rounded transition segment 32 is 3-6 cm.

[0011] According to some embodiments of the present invention, the elastic base 1 is made of an elastic cushioning material to provide ergonomic support. The elastic cushioning material includes, but is not limited to, memory foam, open-cell foam, latex, natural fibers, or any other viscoelastic or resilient material commonly used in the manufacture of cushions.

[0012] According to some embodiments of the present invention, when the portable orthotic cushion undergoes partial deformation under the user's weight, the recess 3 can still maintain an air gap of at least 1 cm with the user's body. The ventilation gap can be used to improve ventilation and reduce pressure on the pelvic organs.

[0013] According to some embodiments of the present invention, the support area 22 is provided with an anatomical recess inclined at 10°-20° to achieve body stability and uniform pressure distribution, and to fix the pelvic organs and spine in the middle of the recess 3 (i.e., the air channel).

[0014] According to some embodiments of the present invention, the support area 22, the first rounded transition section 32, the side wall 31, the bottom 33, and the second rounded transition section 34 constitute a continuous arc-shaped system, providing shock absorption, ventilation, ergonomic support, and fixing the pelvic organs and spine in the middle of the air channel.

[0015] According to some embodiments of the present invention, the bottom 33 of the recess 3 is provided with a reinforcing structure, which is selected from one of the following: a mesh layer embedded in the bottom; or a reinforcing tape pasted on the bottom surface.

[0016] According to some embodiments of the present invention, the portable orthopedic cushion may further include a cushion cover, which is detachably covered to the main body of the cushion, and the bottom surface of the cushion cover is provided with an anti-slip structure.

[0017] According to some embodiments of the present invention, the surface of the seat cover has a moisture-proof, antibacterial, or mildew-proof layer.

[0018] This invention features a recessed section extending across the entire width of the elastic base of a portable orthotic cushion. This ensures that the pelvic organs do not come into contact with the cushion during use, reducing pressure on hemorrhoid tissue and the prostate area, thus helping to prevent and alleviate prostatitis. Furthermore, the recessed section provides ventilation, allowing the skin in the recessed area to breathe freely, preventing heat and moisture buildup. A smooth, rounded transition section provides correct pelvic positioning and a stable sitting posture, redistributing pressure loads to the support area. This avoids localized stress concentration at the edges and prevents the recess from narrowing significantly under load. Simultaneously, the combination of a ventilated air channel design and smooth transition support achieves load distribution, reducing pressure loads on the lumbar, sacral, and spinal vertebrae, maintaining their physiological curvature, and preventing congestion, significantly improving comfort during prolonged sitting.

[0019] Another objective of this invention is to provide a portable seat cushion that is easy to transport and can withstand huge loads during transportation and handling while maintaining structural integrity, so as to avoid producing defective products.

[0020] Another objective of this invention is to provide an orthopedic seat cushion that corrects the user's posture through a smooth support section with an arc-shaped profile, thereby reducing pressure on the lumbar spine and spine. Attached Figure Description

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0038] Existing universal seat cushions fail to create an effective ventilation gap between the pelvic organs and the cushion to prevent the pelvic organs from contacting the cushion (such as the surface or the bottom of the groove). As a result, prolonged use can lead to the accumulation of heat and moisture, which can induce pelvic organ eczema or bacterial growth. Furthermore, when using existing universal seat cushions, the depth and width of the rectangular grooves become significantly narrower under load, and the right-angled edges or sidewalls of the rectangular grooves can cause local stress concentration, which can aggravate damage to the soft tissues of the ischium. At the same time, it makes it impossible to evenly distribute the pressure load in the perineal and sacral regions.

[0039] To at least partially address one of the technical problems existing in current products, this invention proposes a portable orthopedic cushion with better ventilation, cushioning performance, and ergonomic support.

[0040] According to an embodiment of this utility model, the provided portable orthotic cushion is an orthotic and preventative cushion product designed to reduce pressure on pelvic organs, reduce spinal load, and improve ventilation when a user sits for extended periods. This portable orthotic cushion provides comfort for users suffering from prostate diseases (e.g., prostatitis, benign prostatic hyperplasia) and hemorrhoids, alleviating lumbar muscle strain and sacral pain caused by prolonged sitting, preventing impaired blood circulation in the genital and sacral regions, and thus preventing the occurrence of the aforementioned diseases.

[0041] This utility model of a portable orthotic cushion is as follows: Figures 1 to 4 As shown. Reference Figure 1 and Figure 2 The disclosed portable orthotic cushion includes a main body comprising an elastic base 1 and an upper surface 2. The upper surface 2 includes at least two support areas 22, such as a left support area and a right support area. The elastic base 1 has a recess 3 extending through its width W in the middle, forming a longitudinal air channel through the middle of the elastic base 1. The air channel is designed to completely avoid physical contact between the cushion surface and the pelvic organs or spine. When in use, the longitudinal air channel constitutes an effective ventilation gap, preventing the pelvic organs from contacting the bottom 33 of the recess 3. Figure 1 and Figure 2 As shown, the sidewall 31 of the recess 3 and the upper surface 2 form a continuous arc-shaped profile through a smooth first rounded corner transition section 32. When the user uses it, compared with the rectangular recess of a general seat cushion, the first rounded corner transition section 32 avoids the pressure compression of the sharp edge area or sidewall of the rectangular recess, which can reduce damage to the soft tissue of the ischium.

[0042] See Figure 1 and Figure 2 In some embodiments of this utility model, the cross-section of the recess 3 is U-shaped or semi-circular. The support area 22 is inclined at 10°-20° (e.g., Figure 2 The anatomical depression (shown by the slope angle α). See also... Figure 1 and Figure 2 The support area 22 forms a contoured surface that conforms to the shape of the human buttocks. This contoured surface is specifically designed to distribute body weight evenly across the surface of the cushion, helping the body (especially the pelvic organs and spine) to move along the central axis of the central concave portion 3. Figure 3 (Shown as dashed line) Centered along the longitudinal air channel, this structure ensures correct posture and balanced pressure distribution. The contoured surface combined with the first rounded transition section 3 provides ergonomic adaptive support, thereby evenly distributing weight to reduce the load on the spine.

[0043] In some embodiments of this utility model, the bottom 33 of the recess 3 serves as a connecting layer, and the bottom 33 can be structurally reinforced, such as by reinforcing the structure of the bottom 33 with reinforcing elements to prevent tearing or deformation. The structural reinforcement of the bottom 33 can be achieved by: embedding a mesh or wire mesh structure during the manufacturing process of the elastic base 1; coating or pasting an adhesive plastic strip on the bottom 33 to prevent tearing or deformation during use; increasing the thickness of the bottom 33; or using a more durable connecting material between the two support areas 22 or using any other reinforcing material to strengthen the bottom 33.

[0044] By providing the recess 3, it is possible to ensure that the pelvic organs do not come into contact with the sidewalls 31 and bottom 33 of the recess 3 under load, thus creating an effective ventilation gap between the pelvic organs and the bottom 33 of the recess 3. This keeps the pelvic organs suspended, allowing the skin at the pelvic organs to breathe freely and preventing the accumulation of heat and moisture. Simultaneously, the arrangement of the recess 3 helps reduce pressure on the lumbar and sacral vertebrae, preventing and alleviating prostatitis and hemorrhoids. The smooth connection of the first rounded transition section 32 eliminates discomfort caused by sharp edges or sidewalls when the user is seated, reducing local pressure points. Furthermore, the smooth first rounded transition section 32 prevents the recess 3 from narrowing significantly under load. When a seated user applies weight, the vertical sidewalls of the rectangular recess or air channel tend to move within the air channel, reducing the width of the air channel or recess. The smooth first rounded transition section 32, acting as a support element, effectively avoids this, stabilizing the geometry of the recess 3 and maintaining its ventilation capacity under load.

[0045] like Figure 2 and Figure 3As shown, in some embodiments of this utility model, the width k of the recess 3 is 6-10 cm, the depth d is 5-7 cm, and the length of the recess 3 is slightly smaller than or equal to the width W of the elastic base 1. The smooth first rounded transition segment 32 has a radius of curvature of 3-6 cm. Those skilled in the art can adjust the above dimensions according to actual needs.

[0046] Continue to refer to Figure 1 and Figure 2 In some embodiments of this invention, the bottom 33 of the recess 3 is provided with a smooth second rounded corner transition section 34, the radius of curvature of which is 4-8 cm. The arc shape (radius of curvature) of the second rounded corner transition section 34 not only conforms to ergonomics but also plays a crucial role in preventing breakage. General-purpose cushions with rectangular grooves or vertical sidewalls often accumulate stress at the sharp bottom corners of the grooves, leading to material failure over time. In contrast, in the portable orthotic cushion of this invention, the load is redistributed by setting a smooth second rounded corner transition section 34 to increase structural stability. This conclusion has been verified by classical mechanics and materials mechanics theory, especially considering that the cushion of this invention is portable and will withstand various physical stresses.

[0047] According to some embodiments of the present invention, the elastic base 1 of the portable orthopedic cushion is made of an elastic cushioning material, including but not limited to memory foam, perforated foam, latex, natural fibers, or any other viscoelastic or resilient material commonly used in the manufacture of cushions.

[0048] The combination of the first rounded transition section 32, the second rounded transition section 34, and the elastic base 1 with its elastic cushioning structure allows for maximizing the retention of the working space in the recess 3 by absorbing and compensating for the deformation load generated by the user's weight when seated. The smaller radius of the second rounded transition section 34 prevents tearing or damage to the elastic cushioning structure of the portable orthopedic cushion. The construction of the second rounded transition section 34 prevents critical pressure or stress concentration at the corners of the recess 3 during compression and bending loads, enhancing durability, thereby maintaining the integrity of the elastic cushioning structure and extending the cushion's lifespan.

[0049] According to the portable orthotic cushion of this utility model, when a user sits down, their body weight is evenly distributed on the support area 22 of the cushion, and the central recess 3 remains completely out of contact with the body. Even if the cushion deforms partially under the user's weight, a ventilation gap of at least 1 cm can still be maintained in the recess 3, that is, the depth d of the recess 3 is at least 1 cm under load. Specifically, as shown... Figure 2As shown, due to the protruding first rounded transition section 32 and the second rounded transition section 34 of the bottom 33 between the recess 3 and the upper surface 2, under load, the protruding first rounded transition section 32 and the second rounded transition section 34, combined with the support area 22 with a contoured curved surface, uniformly distribute the pressure load, ensuring that the depth d of the recess 3 is at least 1 cm (i.e., the ventilation gap is at least 1 cm), and maximizing the horizontal width of the longitudinal air passage to maintain functional space under compression. Therefore, the recess 3 provides good ventilation comfort for the pelvic organs, while the support area 22 reduces pressure on the lumbar and sacral vertebrae, supporting and correcting the user's physiological posture to prevent congestion.

[0050] In some embodiments of this invention, the portable orthopedic cushion further includes a cushion cover that covers or wraps around the cushion body. The cushion cover can be fixed or removable and is made of textiles, synthetic materials, natural leather, artificial leather, or other composite materials. Other composite materials include, but are not limited to, cotton, polyester, viscose, silk, wool, leather, PU leather, or other natural or artificial materials commonly used in cushion manufacturing. The surface of the cushion cover has a moisture-proof, antibacterial, or anti-mildew layer, and has good breathability and hypoallergenic properties. The bottom surface of the cushion cover can be treated with an anti-slip finish, such as striping, coating with an anti-slip coating, or adding granular protrusions to the cover surface. Figure 5 As shown, the bottom surface of the seat cover has raised stripes at equal or unequal intervals to prevent it from shifting during use.

[0051] In some embodiments of this utility model, the bottom surface of the elastic base 1 of the portable orthopedic cushion may also be treated with anti-slip treatment, including but not limited to stripe treatment or setting mesh protrusions, wherein the stripes or protrusions may be arranged at equal or unequal intervals.

[0052] like Figures 1 to 3 As shown, in some embodiments of this utility model, the length L of the elastic base 1 of the portable orthotic cushion is 45cm, but it can be greater or less than 45cm; the width W of the elastic base 1 is 36cm, but it can be greater or less than 36cm; the overall height H of the elastic base 1 is 8cm, but it can be greater or less than 8cm. In the embodiments, the size of the portable orthotic cushion (45x36x8cm) refers to the standard universal adult size, but this utility model allows for adjustments in both horizontal and vertical dimensions. For example, a smaller version can be provided for children, or a larger and thicker version can be provided for heavier individuals; that is, the size of the portable orthotic cushion can be adapted according to the user's weight and age. Accordingly, the depth d of the recess 3 is less than the height H of the elastic base 1, such as... Figure 1 and Figure 2As shown. The depth d of the recess 3 can be adjusted while ensuring that it is less than the height of the elastic base 1. Those skilled in the art can make adjustments or modifications according to actual needs, and all such adjustments or modifications fall within the scope of this utility model.

[0053] like Figure 4 As shown, the side view of the portable orthotic cushion is shown as a basic rectangular shape. The top view of the elastic base 1 is as follows. Figure 3 As shown, while ensuring that the recess 3 extends through the width W of the elastic base 1, those skilled in the art can adjust or modify the three-dimensional shape of the elastic base 1, without limitation.

[0054] In some embodiments of this invention, the sidewalls 31 (including the left and right sidewalls) of the recess can be straight, convex, concave, or wavy. Variations in the geometry of the sidewalls 31 do not alter the basic function of the recess, namely, reducing pressure on the pelvic organs, alleviating spinal load, and improving ventilation. All these variations fall within the scope of this invention. The portable orthotic cushion of this invention, through the support area 22, the first rounded transition section 32, the sidewalls 31, the bottom 33, and the second rounded transition section 34, forms a continuous arc-shaped system, providing cushioning and pressure relief, ventilation, and ergonomic support, and fixing the pelvic organs and spine in the middle of the air passage; furthermore, the contour formed by the first rounded transition section 32, the sidewalls 31, the bottom 33, and the second rounded transition section 34 prevents excessive horizontal deformation of the recess 3, thereby enhancing the function of the ventilation passage.

[0055] In alternative embodiments of this invention, the portable orthotic cushion may include not only the features, parts, or elements described in the above embodiments (such as the elastic base 1, upper surface 2, support area 22, recess 3, sidewall 31, first rounded corner transition section 32, bottom 33, second rounded corner transition section 34, etc.), but may also include at least one film or partition. This film may be disposed on the upper surface 2 or support area 22 of the portable orthotic cushion and may have an ergonomic shape to help secure the user's body in place and prevent backward movement during use. This variant of the portable orthotic cushion possesses all the functions described in the above embodiments, and will not be repeated here. Alternative embodiments of this invention may also be broadly included, individually or collectively, in the parts, elements, and features referred to or cited herein.

[0056] This portable orthotic cushion can achieve ventilation, reduce moisture accumulation, correct sitting posture, prevent and alleviate pelvic and spinal diseases, and has been verified by ergonomic testing.

[0057] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. The various embodiments of the present invention are intended to be illustrative and not restrictive. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention. Furthermore, the embodiments and features described herein can be combined with each other unless otherwise specified.
