Description

Technical Field

[0001] This utility model relates to the field of wheelchair cushion technology, and in particular to a wheelchair cushion that prevents pressure injuries. Background Technology

[0002] Pressure injuries are localized injuries to the skin and / or soft tissues at bony prominences or under medical or other instruments caused by strong and / or prolonged pressure or combined pressure and shear force. Elderly individuals have increased skin vulnerability due to factors such as dulled skin sensation, thinning subcutaneous fat, and decreased skin elasticity. Therefore, under the same pressure and duration of exposure, older adults are more prone to pressure injuries than younger individuals.

[0003] There is an increased risk of pressure injury to the sacrum and coccyx in hospitalized elderly patients using wheelchairs. Currently available cushions designed to prevent pressure injury are mostly hollow, which limits the range of pressure adjustment and makes them unsuitable for thin patients. Prolonged use can also hinder blood circulation around the hollow area, resulting in poor effectiveness in preventing pressure injury. Utility Model Content

[0004] The main purpose of this invention is to provide a pressure-resistant seat cushion for wheelchairs, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A wheelchair cushion for preventing pressure injuries includes a knitted outer fabric, inside which a matching memory foam is placed. A knitted cover is sewn to the top of one side of the knitted outer fabric. The memory foam has a hollow suture for sacrococcygeal process decompression and two hollow sutures for ischial process decompression on the side of the pelvic floor. The bottom of the memory foam has placement cavities corresponding to the bottom of the hollow sutures for sacrococcygeal process decompression and the two hollow sutures for ischial process decompression on the side of the pelvic floor. Each of the three placement cavities has an anti-pressure airbag attached to it.

[0007] Preferably, each of the three pressure-resistant airbags is equipped with a flexible tube, which passes through the memory foam and the knitted fabric outer covering, respectively, and the remaining end of each of the three flexible tubes is equipped with an inflation nozzle.

[0008] Preferably, the memory foam has a hip-shaped concave surface on both sides of its top.

[0009] Preferably, the knitted cover fabric and the woven outer cover fabric are connected and sealed by a zipper assembly.

[0010] Preferably, an anti-slip patch is fixedly connected to the bottom of the outer surface of the woven outer fabric.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. By setting the curved concave surface of the buttocks and the memory foam to conform to the curve of the human body sitting posture, the hollow suture for decompression of the sacrococcygeal process is set to correspond to the position of the human sacrum and coccyx. The two hollow sutures for decompression of the ischial process of the lateral pelvic floor correspond to the positions of the left and right lateral pelvic floor ischial bones of the human body, respectively. The gaps are closed when there is no pressure and open to a certain width when there is pressure, so as to reduce the gravitational pressure at the bony prominence and achieve buffer decompression at the corresponding position.

[0013] 2. By setting up pressure-resistant airbags, the size can be controlled according to the body weight and the location of pressure requirements, thereby realizing pressure adjustment. It has strong applicability and the adjustment operation is also relatively convenient.

[0014] 3. The entire device is simple to prepare and inexpensive, reduces the occurrence of pressure injuries in patients, reduces nursing workload, and alleviates the nursing burden on family members. The cushion is easy to use, washable, detachable, and easy to carry. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-5As shown, a wheelchair cushion for preventing pressure injuries includes a knitted outer fabric 1, inside which a matching memory foam 4 is placed. A knitted cover fabric 2 is sewn to the top of one side of the knitted outer fabric 1. The memory foam 4 has a sacrococcygeal process decompression hollow suture 61 and two lateral pelvic floor ischial process decompression hollow sutures 62. The bottom of the memory foam 4 has placement cavities 11 corresponding to the bottom of the sacrococcygeal process decompression hollow suture 61 and the two lateral pelvic floor ischial process decompression hollow sutures 62. Each of the three placement cavities 11 has an anti-pressure airbag 10 attached to it.

[0023] In this embodiment, each of the three pressure-resistant airbags 10 is equipped with a flexible tube 9. The three flexible tubes 9 pass through the memory foam 4 and the knitted outer fabric 1 respectively. The remaining end of each of the three flexible tubes 9 is equipped with an inflation nozzle 7. The top two sides of the memory foam 4 are provided with a hip-shaped concave surface 5.

[0024] Specifically, by setting up the pressure-resistant airbag 10, the size can be controlled according to the body weight and the pressure required at the location, thereby realizing the pressure adjustment. It has strong applicability and the adjustment operation is also relatively convenient. The whole device is simple to prepare and low in cost, reducing the occurrence of pressure injury to patients, reducing nursing workload, and reducing the nursing burden on family members. The cushion is easy to use, washable and detachable, and easy to carry and take away.

[0025] In this embodiment, the knitted cover fabric 2 and the woven outer cover fabric 1 are connected and sealed by a zipper assembly 3; an anti-slip patch 8 is fixedly connected to the bottom of the outer surface of the woven outer cover fabric 1.

[0026] Specifically, by setting the curved concave surface 5 of the buttocks and the memory foam 4 to conform to the curve of the human body sitting posture, the sacrococcygeal process decompression hollow suture 61 is set to correspond to the position of the human sacrum and coccyx, and the two lateral pelvic floor ischial process decompression hollow sutures 62 correspond to the positions of the left and right lateral pelvic floor ischial bones, respectively. The sutures are closed when there is no pressure and open to a certain width when there is pressure, so as to reduce the gravitational pressure at the bony prominence and achieve buffer decompression at the corresponding position.

[0027] Working principle: The shape of the woven outer covering fabric 1 in this utility model is adapted to the shape and size of the wheelchair. The anti-slip patch 8 can be anti-slip rubber or a Velcro structure that adheres to the surface of the wheelchair seat, which can fix the seat cushion and prevent it from sliding. The length of the lateral pelvic floor ischial process decompression hollow suture 62 is usually 5cm. The sacrococcygeal process decompression hollow suture 61 corresponds to the position of the human sacrum and coccyx. The two lateral pelvic floor ischial process decompression hollow sutures 62 correspond to the positions of the left and right lateral pelvic floor ischial bones, respectively. The knitted cover fabric 2 is an elastic and soft knitted fabric. The woven outer covering fabric 1 is a stronger and non-elastic woven fabric, or it can be leather. The air inflator 7 can inflate and deflate. The air inflator 7 has a connection port for connecting an external air pump. This utility model sets the buttock arc concave surface 5 and The memory foam 4 conforms to the human body's sitting posture curve, with a hollow suture 61 for decompression of the sacrococcygeal process corresponding to the position of the sacrum and coccyx, and two hollow sutures 62 for decompression of the ischial processes on the left and right sides of the pelvic floor corresponding to the positions of the ischial processes. The sutures close when there is no pressure and open to a certain width when there is pressure, reducing the gravitational pressure at the bony processes and achieving buffering and decompression at the corresponding positions. The anti-pressure airbag 10 can be adjusted in size according to the body weight and the pressure required at the location, thus achieving pressure adjustment. It has strong applicability and is easy to adjust. The entire device is simple to manufacture and low in cost, reducing the occurrence of pressure injuries in patients, reducing nursing workload, and reducing the burden of care on family members.
