Description

Technical Field

[0001] The present invention relates to the technical field of pressure ulcer prevention devices, and specifically to a pressure ulcer prevention device for position adjustment of critically ill patients. Background Technique

[0002] Pressure ulcers, commonly known as bedsore, are an injury disease caused by long-term compression of the skin. The main symptoms are skin redness, ulceration, and even necrosis. This kind of injury mostly occurs in the parts where the bones of the body protrude, such as the coccyx, heels, buttocks and other places that come into contact with the bed surface for a long time. When a person lies or sits still for a long time, the blood circulation in these compressed parts is not smooth, and the skin and the underlying tissues do not get enough nutrition, which will cause skin ulceration and even necrosis.

[0003] Among them, the "pressure ulcer prevention method based on small turning movement of an airbag nursing mattress" disclosed in the publication number "CN114699257B" is also an increasingly mature technology. Its "airbag nursing mattress includes two groups of left and right turning airbags arranged along the length direction of the bed body. One group of left turning airbags is on one side, and one group of right turning airbags is on the other side. Two side protection airbags are symmetrically arranged outside the turning airbags. The two groups of left and right turning airbags are in the middle, and the protection airbags are on both sides. Each airbag is externally connected to a pressure sensor for monitoring the pressure inside the airbag. The host computer obtains the information of the monitored pressure sensor, and each group of turning airbags inflates or deflates simultaneously. By controlling the airbag deflation to achieve small turning movement, the pressure between the human body and the airbag is reduced, so that the pressure on the human body can be adjusted and not concentrated under pressure for a long time, thereby preventing the generation of pressure ulcers. The present invention is particularly suitable for intensive care units, can effectively prevent the generation of pressure ulcers in critically ill patients, and can reduce the nursing difficulty of nursing staff and maintain the life health and safety of critically ill patients.

[0004] When the traditional pressure ulcer prevention device prevents pressure ulcers for patients, it can only adjust the nursing bed as a whole for position adjustment, and cannot perform local position positioning adjustment, which causes discomfort to the patients. At the same time, when the patient lies flat on the nursing bed and turns over, multiple people are needed to assist in turning over, which causes inconvenience. Summary of the Invention

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] The present invention provides a pressure ulcer prevention device for the body position adjustment of critically ill patients:

[0015] 1. Adjust the position of symptomatic patients to prevent pressure ulcers. Since critically ill patients are prone to pressure ulcers when lying flat for a long time, it is necessary to adjust the patient's position irregularly. It is necessary to use pressure ulcer prevention equipment for adjustment to avoid the situation where medical staff manually adjust the position inaccurately. Through the rotation adjustment between the first small drive motor, the rotating shaft and the meshing gear, it is convenient to engage and rotate with the rack to drive the moving frame to adjust the position. The roller slides on the limit slide rail to make the moving frame move to the appropriate position, so as to facilitate the adjustment of the body position pressure ulcers of critically ill patients. By rotating the second small drive motor to drive the threaded screw rod to rotate, the lifting and folding frame can be telescopically lifted, which is convenient for the hydraulic rod on the top of the lifting and folding frame to push the bed board, so as to adjust the body position pressure ulcers of critically ill patients.

[0016] 2. Since critically ill patients need to turn over irregularly to prevent pressure ulcers caused by the adjustment of the body position of critically ill patients, it is necessary to turn over the patients to prevent pressure ulcers caused by maintaining a single position for a long time. By rotating the third drive motor to drive the small screw rod to rotate, it is convenient for the moving seat sliding on the first guide rod to move back and forth during the rotation of the small screw rod. When the moving seat slides back and forth, it drives the first movable hinge seat to adjust, so that the first movable hinge seat drives the adjusting arm to drive the second movable hinge seat to drive the bottom bed board to adjust the angle, so that the bottom bed board tilts the critically ill patient, which is convenient for medical staff to turn over the critically ill patient.

[0017] 3. When turning over a critically ill patient, the telescopic movement of the electric hydraulic rod drives the turning board frame movably connected to the top of the turning fixed frame, which is convenient for adjusting the turning of the critically ill patient.

A regulating arm 307 is movably connected to the top of the first movable hinge seat 306. One end of the regulating arm 307 is movably connected with a second movable hinge seat 308. The top and bottom of the second movable hinge seat 308 are connected to the bottom bed plate 309. The other end of the angle adjustment frame 301 is movably connected with a rotating rod 3010. Both ends of the rotating rod 3010 are movably connected with connecting plates 3011. The top of the connecting plate 3011 is fixedly connected with the bottom bed plate 309.

[0038] During specific use, since critically ill patients need to be turned over irregularly to prevent pressure ulcers caused by body position adjustment of critically ill patients, the patients need to be turned over to prevent pressure ulcers due to the patients maintaining a single position for a long time. By rotating the third drive motor 302, the small lead screw 303 is driven to rotate. During the rotation of the small lead screw 303, it is convenient to drive the moving seat 304 sliding on the first guide rod 305 to move back and forth.
