Description

Technical Field

[0001] The utility model relates to the technical field of turning-over pillows, in particular to an anti-skid turning-over pillow with adjustable angles. Background Art

[0002] In clinical nursing work, regular turning over is a simple and effective method to prevent pressure sores. Turning over pillows are commonly used tools in nursing activities. When performing turning over operations, nurses will place turning over pillows behind patients to achieve the purpose of supporting left or right side-lying positions and making patients comfortable. For example, a non-slip turning over pillow with publication number CN214761913U is provided. By providing a first turning over pillow and a second turning over pillow, the patient can lie between the first turning over pillow and the second turning over pillow when in use. The first turning over pillow and the second turning over pillow are connected by a connecting belt. After lifting the patient's back, medical staff can push the first turning over pillow or the second turning over pillow into the patient's back, so that the patient can lean on the inclined surface and keep the patient lying on his side. The turning pillow arranged behind the patient is connected to another turning pillow through a connecting belt and is hindered by a certain pulling force and friction force, so that when the patient leans on the turning pillow, the turning pillow is not easy to slide outward, thereby reducing the workload of the nursing staff; by providing a first Velcro on the turning pillow and a second Velcro on the connecting belt, the first Velcro is a fleece surface, and the second Velcro is a hook surface, the first Velcro can be well bonded with the second Velcro; the nursing staff can attach the second Velcro to a suitable position on the first Velcro according to the length of the connecting belt that needs to be extended, so that the distance between the first turning pillow and the second turning pillow can be adjusted, so as to adapt to the use of patients with different body shapes;

[0003] When the above mechanism is in use, the patient lies between the first turning pillow and the second turning pillow to keep the patient in a side-lying position. However, since the turning pillow is only a fixed triangle, the supporting angle is also fixed. Some patients with severe pneumonia or agglomerative pneumonia need to turn over at a large angle to promote the discharge of sputum. The above mechanism does not have the function of adjusting the angle, resulting in the inability to adjust the support angle according to the usage needs of different patients.

[0004] Therefore, we proposed an anti-slip turning pillow with adjustable angle that can solve the above problems well. Utility Model Content
