Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of patient turning over, especially to a stroke turning over aid. BACKGROUND

[0002] Stroke, also known as apoplexy or cerebrovascular accident, is an acute cerebrovascular disease with high incidence, high disability rate and high mortality. The main types are ischemic stroke and hemorrhagic stroke.

[0003] Before the onset of acute stroke patients, they may experience transient limb weakness, or they may suddenly develop cerebral infarction without symptoms, followed by a series of symptoms such as unilateral limb weakness or numbness, unilateral facial numbness or corner of the mouth distortion, slurred speech, blurred vision, nausea and vomiting, etc.

[0004] After the occurrence of stroke, if the ischemic or hemorrhagic part of the brain tissue affects the motor control center, it may cause the patient to develop hemiplegia, i.e. the inability to normally move one side of the body. At this time, the patient's self-activity ability is limited, and long-term bed rest in the same posture causes the local tissue to be continuously compressed, leading to blood circulation disorders, which can easily cause skin ulceration, necrosis, and pressure sores. Regularly assisting in turning over can change the compression site of the body, allowing the local tissue to rest in turn, promoting blood circulation and reducing the risk of pressure sores. In addition, through assisted turning over and appropriate limb movement, the range of motion of the joints can be maintained, preventing joint contracture and deformity, creating favorable conditions for the patient's later rehabilitation training. Also, changing the patient's body position can relieve physical fatigue and discomfort, improve the patient's comfort and sleep quality, and benefit the patient's physical and mental recovery.

[0005] The existing technology of stroke turning over aid:

[0006] One is, for example, Chinese patent CN219207789U granted on 2023-06-20, which is small in size and easy to use, but can only be clamped between the patient's legs to turn over, and cannot provide support to the patient's whole body after turning over. Another is, for example, Chinese patent CN116473772A published on 2023-07-25, which can achieve support to the patient's whole body after turning over by turning over one side of the bed. However, this structure requires a large degree of modification to the hospital bed, resulting in a large device size, high weight, difficulty in transportation and installation, and a large driving force required.

[0007] Therefore, the above two methods are not practical. A more advanced way is, for example, Chinese Patent CN216136239U granted on March 29, 2022, which winds the bed sheet on both sides of the bed. When one side is wound up, it can lift one side of the bed sheet, which can assist the patient on the bed to turn over. However, in this type of technology, when the bed side winding device needs to be lifted, the entire swing arm (and the roller winding the bed sheet) needs to be controlled to perform a flipping action, resulting in the bed sheet being loose and not being tensioned, which is not good for supporting the patient after turning over. Although it can be manually rolled and tensioned, it needs to be operated against the weight of the patient during the manual process, which is relatively inconvenient.

[0008] Therefore, in summary, the existing winding bed sheet type turning over aid cannot adjust the tension of the bed sheet when the bed side winding device is lifted. In the case where the bed sheet is not tensioned and soft, the supporting effect is limited after the patient turns over, and it cannot be automatically rolled, which is inconvenient to operate.

[0057] Specifically, the first left telescopic member 51 and the first right telescopic member 52 support the left movable shaft 41 and the right movable shaft 42 in a non-vertical manner, so that the left fixed shaft 31 and the right fixed shaft 32 can be hidden under the bed 1, without modifying the bed 1 itself. That is, the device can be assembled on a conventional bed 1, without the need to purchase a specially designed bed 1, thereby reducing the purchase cost of the user. In this case, since the first left telescopic member 51 and the first right telescopic member 52 are connected to the mounting seat 72 in a diagonal manner, the second left telescopic member 81 and the second right telescopic member 82 are used to provide pulling force to the fixed part of the first left telescopic member 51 and the first right telescopic member 52, so as to avoid the mounting seat 72 from being not firmly connected when a patient with a large body weight uses it.
