Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a medical-specific pressure-reducing seat cushion. Background Technology

[0002] Existing seat cushions mostly use ordinary sponge or memory foam materials, which, while providing some cushioning, cannot be optimized for the specific needs of postoperative patients. These cushions typically lack precise distribution of localized pressure, causing pressure to concentrate at the surgical site, increasing patient pain and hindering recovery. Furthermore, traditional seat cushions have poor breathability and hygiene, easily fostering bacterial growth and increasing the risk of postoperative infection.

[0003] Therefore, there is an urgent need for a pressure-reducing cushion that can effectively disperse local pressure, provide comfortable support, and also has good breathability and hygiene to promote postoperative recovery and improve patients' quality of life. Summary of the Invention

[0004] This invention proposes a medical-grade pressure-reducing cushion, which solves the problem that existing cushions often lack precise distribution of local pressure, causing pressure to concentrate at the surgical site, increasing the patient's pain and making recovery more difficult.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A medical-grade decompression cushion includes a cushion body with a buttock groove at the top to accommodate the buttocks, a thigh slope at the top of the cushion body near the buttock groove for placing the thighs, and two calf grooves at the bottom of the cushion body. The patient sits in a kneeling position with the calf grooves of the cushion body securing the calf to the outside of the calf, and sits with the buttocks in the buttock groove and the thighs resting on the thigh slope.

[0007] Furthermore, the front side of the seat cushion body is provided with a popliteal groove corresponding to the calf groove.

[0008] Furthermore, a soft leg pad surrounding the calf is placed in the calf groove.

[0009] Furthermore, the soft leg pads are designed to be recessed on both the front and rear sides relative to the calf groove, with the rear side of the soft leg pads recessing to create a foot groove at the end of the calf groove.

[0010] Furthermore, the rear side of the seat cushion body is provided with an arc-shaped slope adapted to the seat back.

[0011] Furthermore, a soft mesh pad with anti-slip particles is placed in the buttock groove.

[0012] Furthermore, the interior of the seat cushion body is provided with a support base to provide support.

[0013] The beneficial effects of the technical solution provided in this application are as follows:

[0014] This medical-grade pressure-reducing seat cushion, with its hip groove and thigh ramp design, effectively distributes pressure on the patient's buttocks and thighs, reducing direct pressure on the surgical site, thereby alleviating pain, lowering the risk of wound dehiscence and infection, and promoting postoperative recovery. Its ergonomic shape and structure provide comfortable support for the patient. When the patient kneels, the calf groove stably holds the calf, maintaining a comfortable posture, preventing pressure on the calf, and reducing discomfort from prolonged sitting.

[0020] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Reference Figure 1-3A medical-grade pressure-reducing seat cushion includes a seat body 10. The seat body 10 has a hip groove 11 at its top to accommodate the buttocks, and a thigh slope 12 near the hip groove 11 at its top to support the thighs. Two calf grooves 13 are located at the bottom of the seat body 10. The patient sits in a kneeling position, with the calf grooves 13 securing the calves, the buttocks resting in the hip groove 11, and the thighs resting on the thigh slope 12. Through the design of the hip groove 11 and thigh slope 12, this seat cushion effectively distributes pressure on the patient's buttocks and thighs, reducing direct pressure on the surgical site, thereby alleviating pain, reducing the risk of wound dehiscence and infection, and promoting postoperative recovery. The two calf grooves 13 at the bottom of the seat cushion stably hold the patient's calves, allowing the patient to maintain a correct posture while kneeling, preventing calf compression, and reducing discomfort from prolonged sitting. This design not only improves patient comfort but also effectively prevents secondary injuries caused by improper posture.

[0022] It should be noted that the buttock groove 11 extends from the edge towards the center, forming an arc, similar to a small ramp. This arc effectively supports the outer edge of the buttocks, allowing the anus to be suspended in the air, without contacting the cushion, thus significantly reducing pressure on the anus. When the patient sits down, the outer edge of the buttocks is gently supported by this ramp. This support allows the anus to be naturally suspended, not in contact with the cushion surface, thus avoiding direct pressure on the anus. The arc design conforms to the principles of human anatomy, evenly distributing pressure on the buttocks and transferring pressure that would otherwise be concentrated on the anus to other parts of the buttocks.

[0023] In some embodiments, the front side of the cushion body 10 is provided with a popliteal groove 14 corresponding to the calf groove 13. When the patient uses the cushion in a kneeling position, the calf groove 13 secures the outer edge of the calf, the buttocks sit in the buttock groove 11, and the thighs rest on the thigh slope 12. The newly added popliteal groove 14 is located precisely in the popliteal fossa behind the knee. Because the shape and position of the popliteal groove 14 are ergonomically designed, it can effectively distribute the pressure in the popliteal fossa area, avoiding problems such as poor blood circulation or nerve compression caused by prolonged pressure in this area. At the same time, the popliteal groove 14 and the calf groove 13 work together to form a more stable support structure, allowing the patient's legs to receive sufficient support while maintaining a natural bending angle when kneeling, thereby reducing muscle fatigue and joint pressure, and further optimizing the overall pressure relief effect of the cushion.

[0024] In some embodiments, a soft leg pad 15 surrounding the calf is placed in the calf groove 13. The calf groove 13 fastens to the outer perimeter of the calf, and the soft leg pad 15 placed therein tightly surrounds the calf, forming a soft support layer. Due to the elastic properties of the soft leg pad 15, it can evenly distribute the pressure on the calf, avoiding pressure concentration at a certain point, thereby reducing problems such as obstructed blood circulation or nerve compression caused by excessive local pressure. At the same time, the cooperation between the soft leg pad 15 and the calf groove 13 allows the patient's leg to maintain a natural bent position when kneeling, reducing muscle fatigue and joint pressure, further optimizing the pressure-reducing effect of the cushion, and providing a more comfortable and healthy support environment for the patient's postoperative recovery.

[0025] In some embodiments, the soft leg pad 15 is recessed on both the front and rear sides relative to the calf groove 13, with the rear recess of the soft leg pad 15 creating a footrest groove 16 at the end of the calf groove 13. This front-to-back recess of the soft leg pad 15 allows for some movement of the lower leg in the front-to-back direction, enabling it to naturally adjust its position with the patient's slight movements and reducing muscle tension and fatigue caused by excessive fixation. Simultaneously, the footrest groove 16 created at the end of the calf groove 13 by the rear recess of the soft leg pad 15 provides a relatively independent space for the patient's feet, allowing them to maintain a natural posture and avoiding discomfort or obstructed blood circulation in the feet due to the restriction of the footrest groove 16. This design, through the rational allocation of support points and movement space, ensures that the patient's legs receive necessary support and protection while maintaining natural physiological curvature and range of motion when kneeling, thereby further optimizing the pressure-reducing effect and user experience of the cushion.

[0026] In some embodiments, the rear side of the cushion body 10 is provided with an arc-shaped slope 17 adapted to the seat back. When the cushion body 10 is placed on the seat, the arc-shaped slope 17 on its rear side fits snugly against the seat back. Because the arc design of the arc-shaped slope 17 matches the seat back, it increases the friction and fit between the cushion and the seat, thereby preventing the cushion from sliding or shifting due to body movement during patient use. The design of the arc-shaped slope 17 allows the cushion body 10 to fit comfortably on the seat, allowing the patient to sit directly on the cushion body 10 without kneeling. This design provides patients with more usage options; depending on postoperative recovery and personal preference, patients can choose to kneel or sit directly on the cushion. For patients with longer postoperative recovery periods or whose physical condition does not allow for prolonged kneeling, the option of sitting directly increases the cushion's applicability and flexibility. Simultaneously, the design of the arc-shaped slope 17 ensures that even in a sitting position, the cushion still provides good support and pressure distribution, reducing pressure on the surgical site and maintaining comfort and hygiene.

[0027] In some embodiments, a mesh-like soft pad 18 with anti-slip particles is placed in the buttock groove 11. The buttocks rest on the mesh-like soft pad 18 in the buttock groove 11. The anti-slip particles increase friction, ensuring the patient's stability on the cushion and preventing slippage due to body movement. The mesh structure utilizes its breathability to promote air circulation, keep the buttocks skin dry, and reduce bacterial growth. The antibacterial fabric used in the soft pad 18, such as silver ion fiber, bamboo fiber, or gel material, comes into direct contact with the skin, inhibiting the growth of bacteria and fungi, reducing the risk of infection, while its soft texture provides comfortable support for the patient, reducing discomfort during postoperative recovery. This design, through material selection and structural optimization, achieves comprehensive protection and comfortable support for the patient's buttocks, further improving the overall performance and user experience of the cushion.

[0028] In some embodiments, the seat cushion body 10 has a support base 19 inside to provide support. The support base 19 is made of high-density breathable sponge or modified memory foam, which can provide uniform pressure distribution and stable support for the entire seat cushion. The support base 19 is located inside the seat cushion body 10 and serves as the core support structure of the entire seat cushion. Through its high-density material and reasonable shape design, the support base 19 evenly distributes the patient's body weight to various parts of the seat cushion, avoiding pressure concentration at a single point, especially at the surgical site. The material properties of the breathable sponge or modified memory foam allow the support base 19 to maintain good breathability while providing stable support, promoting air circulation inside the seat cushion and reducing bacterial growth and odor caused by moisture.

[0029] In this cushion technology, the cushion body 10 can be made of 3D mesh material or latex. This design significantly enhances the cushion's breathability and elasticity, further distributing pressure on the patient's body. The 3D mesh material or latex has excellent breathability, keeping the cushion surface dry and reducing bacterial growth and skin discomfort caused by moisture. Simultaneously, the high elasticity of these materials allows the cushion to better adapt to different patient body shapes and postures, providing even pressure distribution, reducing pressure on the surgical site, and promoting postoperative recovery. Furthermore, the 3D mesh material or latex is easy to clean, has a smooth surface that doesn't easily retain dirt, and possesses antibacterial and anti-mildew properties, further ensuring the cushion's hygiene, reducing the risk of postoperative infection, and providing patients with a healthier and more comfortable environment.
