Description

Technical Field

[0001] This utility model relates to the field of medical care, and relates to a portable postoperative hip abduction and elevation device. Background Technology

[0002] Femoral neck fracture is a common orthopedic disease in elderly patients, and its incidence has been increasing year by year with the acceleration of population aging. The main symptoms of femoral neck fracture include pain, abduction, and external rotation deformity, which significantly impacts patients' daily activities. Total hip replacement and intramedullary nailing are common clinical treatments for femoral neck fractures, correcting hip joint deformities. With continuous improvements in surgical machinery and materials, postoperative complications have been effectively controlled; however, complications such as hip dislocation and loosening / displacement of internal fixation pins cannot be completely avoided and directly affect the rehabilitation process of patients with femoral neck fractures. Hip dislocation and loosening / displacement of internal fixation pins not only prolong hospitalization and increase financial burden but also significantly impact patients' confidence in rehabilitation and may even lead to hip joint dysfunction. Therefore, actively and effectively preventing hip dislocation and loosening / displacement of internal fixation pins is crucial for improving patient prognosis. Various factors influence hip dislocation and loosening / displacement of internal fixation pins; analysis shows that improper body positioning is one of the main contributing factors. Improper postural control can be corrected using assistive devices. Ideally, assistive devices should fix the hip joint in a specific position, restrict unnecessary movement, reduce the risk of dislocation, and, according to ergonomic principles, promote venous return and relieve discomfort.

[0003] Currently, none of the lower limb pads available to patients' families can integrate abduction and elevation of the affected limb, making them convenient to carry as bedding care products. Utility Model Content

[0014] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model; unless otherwise expressly specified and limited, the terms "installed," "connected," and "joined" should be interpreted broadly, for example, they can refer to fixed connections or detachable connections, etc. For those skilled in the art, the specific meaning of the above terms in this utility model can be understood according to the specific circumstances.

[0015] The following is a description of the embodiments and appendices. Figures 1-2 The technical solution of this utility model will be further described below.

[0016] Example 1 A portable postoperative hip abduction and elevation device includes: a U-shaped inflatable ramp pad 1 and a T-shaped inflatable positioning pad 2. The U-shaped inflatable ramp pad 1 includes a first airbag pad 11 and a second airbag pad 12. The first airbag pad 11 has a placement opening 13 at its top. The second airbag pad 12 is disposed inside a notch 14 at the middle of the high part of the first airbag pad 11. The T-shaped inflatable positioning pad 2 is disposed on one side of the U-shaped inflatable ramp pad 1. The T-shaped inflatable positioning pad 2 has U-shaped grooves 21 on both sides.

[0017] like Figures 1-2 As shown, the working principle of this utility model is as follows: In the early postoperative period, patients often have weak muscles around the hip joint and are unable to maintain proper posture independently. If the lower limbs exhibit adduction or internal rotation, it can easily lead to displacement of the fracture ends or dislocation of the prosthesis. The T-shaped inflatable positioning pad is designed to fit between the legs, and its U-shaped grooves on both sides conform to the curve of the lower limbs, stably restricting the legs within the grooves and providing external support to prevent the lower limbs from adducting or rotating inward, thereby maintaining the hip joint in a neutral abduction position (approximately 15°-30°) and avoiding abnormal stress on the hip joint.

[0018] Postoperatively, the affected limb needs to be moderately elevated to promote venous return and reduce swelling. The first airbag of the U-shaped inflatable ramp cushion serves as the basic support, bearing the weight of the affected limb. The second airbag is embedded in the middle notch of the high part of the first airbag, and the overall elevation can be adjusted by the inflation status. When the patient needs slight elevation, the first airbag alone provides support, elevating the affected limb by at least 15°. When a slightly higher elevation is needed, the second airbag is inflated to further elevate the lower part of the affected limb, up to a maximum of 20°, forming a stepped support to accommodate the venous return needs at different stages of recovery.

[0019] The combination of a U-shaped inflatable ramp pad and a T-shaped inflatable positioning pad meets the needs after femoral fracture surgery. It is highly practical in clinical practice and can effectively help patients prevent dislocation caused by improper positioning, improve patient comfort, and promote disease recovery. The inflatable structure makes it easy to carry. The U-shaped inflatable ramp pad has a double airbag setting to meet the different clinical needs of patients for elevating the affected limb.

[0020] As a further preferred embodiment, the first airbag cushion 11 is provided with an airbag outlet valve 111 at its lower part, and a press-type TPU air inlet 112 is provided on the side of the first airbag cushion 11. The second airbag cushion 12 is provided with an airbag outlet valve 121 at its upper part, and a press-type TPU air inlet 122 is provided on the side of the second airbag cushion 12. The narrow part of the T-shaped inflatable level pad 2 is provided with an airbag outlet valve 24, and the wide part of the T-shaped inflatable level pad 2 is provided with a press-type TPU air inlet 25.

[0021] The push-button TPU air inlet utilizes the elasticity of TPU material, allowing for manual inflation. When pressed, the inlet opens, allowing air to enter the airbag; when pressing stops, the elasticity of the TPU causes the inlet to close automatically, eliminating the need for additional inflation tools. The airbag's deflation valve features a one-way exhaust design; simply opening the valve allows for rapid deflation, and the airbag can be folded and retracted after deflation. The push-button TPU air inlet can be manufactured by Shenzhen Jianda Handbag Accessories Co., Ltd. Without the need for air pumps or other tools, patients' families or nurses can inflate the airbag manually, making it suitable for post-operative ward settings. After deflation, the airbag folds into a small unit, significantly reducing its size, allowing patients to easily pack it into their luggage after discharge for convenient home care.

[0022] As a further preferred embodiment, the height of the first airbag cushion 11 below the second airbag cushion 12 is 100mm, the height of the first airbag cushion 11 above the second airbag cushion 12 is 50mm, and the adjustable height of the second airbag cushion 12 is 0~50mm.

[0023] As a further preferred embodiment, the inner layer material of the U-shaped inflatable ramp pad 1 and the T-shaped inflatable positioning pad 2 is a TPU airbag, and the outer layer material of the U-shaped inflatable ramp pad 1 and the T-shaped inflatable positioning pad 2 is a TPU-coated medical-grade fabric. The inner TPU airbag utilizes the high elasticity and flexibility of TPU to adjust its shape according to the inflation volume, conforming to the physiological curves of the hip joint and lower limbs. It provides sufficient support to limit abnormal movement without causing pressure due to excessive material rigidity. The outer TPU-coated medical-grade fabric has good skin-friendliness and biocompatibility, and is waterproof and stain-resistant, meeting the hygiene requirements of medical settings.

[0024] As a further preferred embodiment, the T-shaped inflatable positioning pad 2 is fixed with straps 22 on both sides. Postoperative patients need to be turned regularly to prevent pressure sores, but the T-shaped positioning pad is prone to displacement during turning, losing its positional fixation function. The straps can fix the T-shaped pad to the patient's legs or the bed sheet, and the straps restrain the position of the T-shaped pad and lower limbs during turning, preventing the pad from slipping or shifting.

[0025] As a further preferred embodiment, a mirror 23 is connected to the lower end of the T-shaped inflatable positioning pad 2 via a thin string. Postoperatively, the heel is a common site for pressure ulcers, and nurses need to regularly check the condition of the heel skin. However, directly lifting the affected limb to check can strain the hip joint, potentially causing pain or affecting the wound. The mirror, suspended from the lower end of the T-shaped pad by a thin string, can be adjusted to reflect the heel area, allowing nurses to observe the heel skin condition without moving the affected limb.

[0026] As a further preferred embodiment, the bottom of the first airbag pad 11 and the T-shaped inflatable position pad 2 are provided with silicone anti-slip particles, which can conform to the bed surface and reduce the slippage of the pad.

[0027] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
