A pillow for maintaining a prone position in a patient following hip fracture surgery

Abstract

The application provides a pillow special for keeping a prone position of a patient after hip fracture surgery, which comprises a head pillow, a chest and abdomen pillow, a knee pillow and a foot pillow, wherein the head pillow is configured as a "U" shape, and a groove is arranged at the bottom; the chest and abdomen pillow is in a slope shape; the knee pillow is in a structure with high sides and a low middle part for accommodating knees, and is divided into a left knee pillow and a right knee pillow by a limiting pad; and the foot pillow is in a cuboid structure. Compared with the prior art, the application is convenient for nurses and family members to place a conscious patient in a prone position and is beneficial for the patient to keep the position. Moreover, the application also takes into account the problem that some patients with hip fracture need to keep an abduction neutral position to prevent excessive internal rotation of the hip joint and even cause hip dislocation.

Description

Technical Field

[0001] This application relates to medical postoperative recovery, and more particularly to a ventilation mattress for maintaining a prone position in an conscious patient after hip fracture surgery. Background Technology

[0002] With the accelerating aging of society, the medical issues of elderly patients have become a key concern for public health. Hip fractures in the elderly refer to low-energy proximal femoral fractures occurring in patients over 65 years of age, mainly including femoral neck fractures, intertrochanteric fractures, and subtrochanteric fractures. It is one of the most common fracture types in elderly patients, and its incidence increases with age. With the development of surgical techniques and the maturation of perioperative management models, current views and guidelines recommend early surgical treatment as the preferred treatment option for elderly patients with hip fractures, helping them shorten bed rest time and begin functional exercises earlier.

[0003] Postoperative mortality rates remain high among elderly patients with hip fractures. The majority of deaths are not caused by the fracture itself, but by pressure injuries, thrombosis, infection, and other surgery-related complications. Postoperative pulmonary complications, in particular, have become a challenging clinical problem due to their high incidence and severe impact on patient prognosis.

[0004] Lung function training during surgery is an effective measure to prevent postoperative pulmonary complications. The induced spirometry method, which encourages patients to breathe deeply, is widely advocated and used due to its simplicity, ease of implementation, and low cost. The prone position can reduce the vertical pleural pressure gradient, decrease lobar compression, preferentially distribute pulmonary blood perfusion to the dorsal region, reduce pathological conditions caused by abnormal alveolar tension and stress changes, and limit excessive expansion of healthy areas. This improves lung expandability and hemodynamics, optimizes the ventilation-perfusion ratio, reduces airway resistance, increases the oxygenation index, promotes alveolar expansion, and reduces the risk of infection. Simultaneously, the prone position can improve lung compliance, reduce pulmonary edema and lung injury, and reduce local inflammation by decreasing the release of inflammatory factors and cell damage, thereby improving the local immune microenvironment and protecting lung tissue.

[0005] Therefore, there is an urgent need for a device that can ensure the quality of prone ventilation and better help patients to be placed in the prone ventilation position. Summary of the Invention

[0006] The purpose of this application is to provide a device that ensures the quality of prone ventilation and better helps patients to be placed in a prone ventilation position.

[0007] This application discloses a pillow for maintaining a prone position in patients after hip fracture surgery. The pillow includes: a head pillow, a chest and abdomen pillow, a knee pillow, and a foot pillow, wherein: The headrest is configured in a "U" shape with a groove at the bottom; The chest and abdomen cushion is sloping, with its highest point being the chest end, and the height of the chest end is not higher than that of the head cushion; the lowest point of the chest and abdomen cushion is close to the ground, which is the abdomen end. The knee pad has a structure that is high on both sides and low in the middle, and is divided into a left knee pad and a right knee pad by a limiting pad; The footrest has a rectangular parallelepiped structure.

[0008] In a preferred embodiment, the head cushion, chest and abdomen cushion, knee cushion, and foot cushion are connected in sequence, and the connection method includes Velcro and snap fasteners.

[0009] In a preferred embodiment, the headrest, chest and abdomen rest, knee rest, and footrest are equipped with air vents, and their size can be adjusted by the air vent strips.

[0010] In a preferred embodiment, the headrest has a length and width of 30-40cm, a height of 10-15cm, and a groove depth of 3-7cm.

[0011] In a preferred embodiment, the chest and abdomen cushion has a length of 50-70cm and a width of 30-50cm.

[0012] In a preferred embodiment, the height of the knee pad on both sides is 10-15cm, the depth of the groove in the middle is 3-7cm, the height of the limiting pad is 5-15cm, the overall length of the knee pad is 17-23cm, and the width is 35-45cm.

[0013] In a preferred embodiment, the top of the footrest is also provided with a semi-circular structure.

[0014] In a preferred embodiment, the cuboid of the footrest pillow has a length of 10-20cm, a width of 30-50cm, and a height of 10-15cm; the semicircular structure disposed thereon has the same length and width as the cuboid, and a radius of 4-6cm.

[0015] In a preferred embodiment, the chest and abdomen cushion has a recess located near the chest end.

[0016] In a preferred embodiment, the headrest, chest and abdomen rest, knee rest, and footrest are covered with waterproof fabric.

[0017] The advantages of this invention are: 1) The design of this utility model makes it convenient for nurses and family members to place conscious patients in a prone position and helps patients maintain their position. The angle and position of the device are well designed, requiring minimal training, making it easy to operate and accessible to a wide range of users.

[0018] 2) This utility model can not only be applied to patients who need to perform pulmonary function exercises after hip fracture surgery such as femoral neck fracture, intertrochanteric fracture and subtrochanteric fracture, but also takes into account some patients who need to undergo hip replacement surgery due to hip fracture, who need to maintain an abducted neutral position to prevent excessive internal rotation of the hip joint or even hip dislocation.

[0019] The specification of this application contains numerous technical features distributed across various technical solutions. Listing all possible combinations of these technical features (i.e., technical solutions) would make the specification excessively lengthy. To avoid this problem, the various technical features disclosed in the above-described invention, the various technical features disclosed in the following embodiments and examples, and the various technical features disclosed in the accompanying drawings can be freely combined to form various new technical solutions (all of which are considered to have been described in this specification), unless such a combination of technical features is technically infeasible. For example, one example discloses feature A+B+C, and another example discloses feature A+B+D+E. Features C and D are equivalent technical means that serve the same function, and technically only one needs to be used; they cannot be used simultaneously. Feature E can technically be combined with feature C. Therefore, the solution A+B+C+D should not be considered as described because it is technically infeasible, while the solution A+B+C+E should be considered as described. Attached Figure Description
