Description

Technical Field

[0001] The invention relates to the technical field of anti-skid devices, in particular to an anti-skid device for critically ill patients lying in a sloped position. Background Art

[0002] Vital signs are unstable, the condition changes rapidly, the functions of more than two organ systems are unstable, and the progression of decline or failure may endanger the patient's life; this type of patient is a critically ill patient. During the treatment of critically ill patients, they need to be placed in a special position and the angle of the bed needs to be adjusted according to the condition.

[0003] At this time, the patient is in a sloped supine position, which is conducive to lung re-expansion and pulmonary oxygenation, reducing cardiac preload, redistributing blood, and improving symptoms of heart failure and respiratory failure. Due to the poor physical condition of critically ill patients, their body or mattress may slide down under the influence of their own gravity and physical exhaustion. When the patient's body or mattress slides down, the patient's feet will be stressed, which will affect the blood circulation of the patient's feet and legs. The upper limb assistive fixation device and the lower limb support device can make the patient's sloped supine position not only improve the patient's comfort and reduce the pain caused by nursing and carrying, but also assist the patient to use reasonable force for self-rehabilitation and functional exercise, which is conducive to cardiopulmonary rehabilitation and lower limb exercise of critically ill patients, and prevents lower limb venous thrombosis. The hinged rotating bed is conducive to wiping nursing operations for critically ill patients, improving the patient's psychological comfort and increasing the patient's physiological comfort.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and an anti-slip device for the sloped lying position for critically ill patients is provided, in order to achieve a more practical purpose. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides an anti-slip device for critically ill patients lying on a slope, so as to solve the problem that although the existing hospital beds can be adjusted in angle, when the hospital beds are adjusted to be tilted, the patient is in a sloped lying position, and under the influence of the patient's own gravity, the body or mattress will slide down. When the patient's body or mattress slides down, the patient's feet will be stressed, which will affect the blood circulation in the patient's feet and legs, posing a great safety hazard.

When the airbag is inflated, it can support the patient's buttocks and reduce the chance of the patient sliding down. Because the airbag itself is relatively soft, it is supported by a soft structure, which can improve the comfort of the patient when supporting.

[0020] In the present application, through the setting of a fixed component, the first motor is controlled to rotate, the first motor drives the first worm to rotate, the first worm drives the two first worm gears to rotate, the two first worm gears drive the first rotating shaft and the mounting arm to rotate and unfold, at this time the fourth electric cylinder is aligned with the mattress, the two fourth electric cylinders are controlled to extend, the two fourth electric cylinders press the mattress, at this time the mattress can be prevented from slipping on the bed, and ultimately the patient is prevented from sliding down, and the mounting arm can be stored after use, with high adjustability.

[0021] In the present application, by setting up the sixth electric cylinder and the pedal, on the one hand, when the patient's feet step on the pedal, it can play an anti-slip role; on the other hand, when adjusting the stepping position, it is only necessary to control the extension and retraction of the two sixth electric cylinders, which has high adjustability.
