Description

A turning pillow after hip replacement

technical field

The utility model belongs to the technical field of post-surgery nursing, in particular to a turning pillow after hip joint replacement.

Background technique

Osteoarthritis (OA) is a chronic degenerative disease of the joints characterized by cartilage degeneration, bone remodeling, osteophyte formation, joint inflammation and loss of normal joint function. Its clinical manifestations are mainly local pain and limited mobility of the joints. OA is a common disease among middle-aged and elderly people, and it occurs in women over 55 years old and men over 65 years old. With the development of the economy and the aging of the population, the number of patients with osteoarthritis is increasing. Osteoarthritis is considered to be one of the most common disabling diseases worldwide. In 2018, Wang Bin et al. conducted a meta-analysis of data from the last 20 years and found that the prevalence of KOA in China is as high as 18%, and the disease burden is heavy. Surgery is usually used in clinical practice, and the surgical method is generally artificial joint replacement surgery.

Demos et al reported that the dislocation rate after primary THA was 3.2% to 6.5%, and the dislocation rate after revision was 7.4% to 11.4%. Some of these dislocations are orthostatic: the prosthesis is in the correct position, the soft tissue is balanced, and the dislocation is caused by inappropriate movement of the affected limb. Dorr et al. divided dislocations after THA into four categories. Category I: Orthostatic dislocation: The prosthesis is in the correct position, the soft tissue is balanced, and the dislocation is caused by inappropriate movement of the affected limb. Class II: Unbalanced dislocation of soft tissue, including high acetabular cup, excessive femoral neck osteotomy, and short femoral neck. Class III: Improper dislocation of the prosthesis. This includes misplacement of cup and stem component position and orientation. Class IV: There are both soft tissue imbalances and malpositioned dislocations. Orthostatic dislocations are mostly caused by improper activities in the early postoperative period. Therefore, how to guide and help patients with early postoperative exercise can effectively reduce the probability of dislocation after hip replacement.

At present, the symptomatic treatment for orthostatic dislocation is mainly through postoperative guidance activities, and prohibition of squatting, cross-legged and other methods. When rolling over early postoperatively, it is common to roll over with a pillow between the knees to avoid excessive internal rotation of the hip, which can cause posterior hip dislocation. However, because the patient or family members did not fully understand, the pillow was incorrectly placed, and the pillow was still in an excessive internal rotation position, resulting in postoperative dislocation of the hip joint.

The existing turning pillow adopts a trapezoidal design with a short top and a long bottom. Mainly considering that after knee surgery, in order to prevent complications such as postoperative bedsores, it may take more than half an hour to turn over. The trapezoidal design of the turning pillow requires the assistance of the patient's family (holding the affected limb so that the patient does not slip out from the surrounding of the turning pillow), and is more suitable for turning over during short-term operations such as bed crossing.

Utility model content

In order to solve some problems existing in the above-mentioned prior art, the purpose of this utility model is to provide a turning pillow after hip arthroplasty, which can effectively reduce post-positional dislocation of hip arthroplasty caused by improper activities after surgery.

In order to achieve the above-mentioned purpose, the present utility model provides a turning pillow after hip joint replacement, which includes an upper top surface, a lower bottom surface, a leg fixing groove and a buckle made of flexible materials. The upper and lower parts of the buckle are respectively fixed on the upper top surface and the lower bottom surface, and the leg fixing groove is between the upper top surface and the lower bottom surface.

Further, its vertical section is "I" shape.

Further, the leg fixing grooves are provided with two, the cross-section of which is quasi-circular, and the quasi-circular diameter is 13-18 cm.

Further, the length of the upper top surface and the lower bottom surface is 50-70cm, and the width is 30-45cm.

The distance between the upper top surface and the lower bottom surface is 15-25cm.

Further, there are 2-5 groups of buckles.

Further, a fixing rope is included, and the fixing rope is cross-wrapped.

Compared with the prior art, in the post-hip replacement pillow provided by the present invention, the leg fixing groove adopts a quasi-circular design, which is more in line with the structure of the human body's legs, and the affected limb can be completely wrapped in the relatively soft pillow surface. , it will not make the patient feel uncomfortable for too long, and it does not require a person to support the affected limb to prevent the affected limb from slipping out from the shorter side. Multiple sets of buckles fix the thighs and calves on both sides, thereby limiting the range of motion of the knee joints, and will not cause the knee joints to cross due to improper movement during turning over, resulting in excessive internal rotation of the hip joint and causing posterior dislocation of the hip joint .

Detailed ways

In order to make the purpose, technical solutions and advantages of the present utility model more clearly understood, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not intended to limit the present invention.

The embodiment of the present invention provides a turning pillow after hip replacement, comprising an upper top surface 1, a lower bottom surface 2, a leg fixing groove 3 and a buckle 4 made of flexible materials, and the buckle 4 is provided with multiple sets, each The 4 upper and lower parts of the group buckle are respectively fixed on the upper top surface 1 and the lower bottom surface 2 , and the leg fixing groove 3 is between the upper top surface 1 and the lower bottom surface 2 .

With the above structure, the upper top surface 1 and the lower bottom surface 2 form a fixed support for the leg fixing groove 3, so that the affected limb can be completely wrapped in the soft leg fixing groove 3, and the patient will not feel the pain due to the long time. It is uncomfortable and does not require another person to support the affected limb to prevent the affected limb from slipping off the shorter side and causing damage to the hip joint. Multiple sets of buckles 4 fix the thighs and calves on both sides, thereby limiting the range of motion of the knee joints, and will not cause the knee joints to cross due to improper movement when turning over, resulting in excessive internal rotation of the hip joint and causing hip joint back. dislocation.

The vertical cross section of the turning pillow in this embodiment is an "I" shape, and two leg fixing grooves 3 are provided. Perfect fit for the affected limb.

The length of the upper top surface 1 and the lower bottom surface 2 is 50-70 cm, and the width is 30-45 cm. In this embodiment, the length is preferably 60 cm and the width is 37 cm.
