Description

Technical Field

[0001] The invention relates to the technical field of critical care nursing, in particular to a turning-over assisting device for critical patients. Background Art

[0002] In the clinical nursing work of the Department of Critical Care Medicine, turning over critically ill patients is a vital nursing task. Since critically ill patients are often accompanied by multiple organ damage, which leads to symptoms such as poor circulation and low protein edema, the main purpose of nursing is to maintain the patient's vital signs and hemodynamic stability. To prevent secondary injuries, nurses need to regularly assist patients in turning over. For critically ill patients, their physical condition is extremely fragile. During the turning process, if the strength is not properly controlled or the operation is unskilled, it is easy to cause additional pressure or damage to the patient's body; in addition, long-term bedridden patients have extremely high requirements for the cleanliness of bedding. The contamination of bedding will not only affect the patient's comfort, but also may become a breeding ground for bacteria, further increasing the patient's risk of infection. Each time the bed sheets are changed for the patient, multiple nurses need to work together to ensure the safety and smoothness of the operation. This process not only wastes manpower, but also cannot guarantee work efficiency. Summary of the invention

[0003] The present invention provides a turning-over assisting device for critically ill patients, which slightly tilts the patient's body to one side through a turning board, and does not cause a sense of pressure on the other side of the patient's body due to excessive turning angle.

[0037] As a technical solution of the present invention, the surface of the turning board 43 is made of smooth material. The turning board 43 is composed of two sections, the upper section is inclined, and the lower section is horizontally arranged. The inner side of the turning board 43 is arc-shaped, so that the patient's body can be slightly tilted, and the other side of the patient's body will not be oppressed due to the excessive turning angle.

[0038] The through slot 411 is also composed of two sections, the upper section is arranged obliquely, and the lower section is arranged horizontally.

[0039] Working principle:

[0040] like Figure 2-6As shown, when the medical staff needs to turn the patient over when changing the bed sheet, the medical staff first clamps one side of the bed sheet with the bed sheet fixing clip 434, and inserts the gear 2 435 and the fixing rod 39 through the bottom of the limiting track 413 into the through groove 411, and then inserts the square block 431 on the turning plate 43 into the square groove 421 at one end of the rack 1 42. At this time, the bed unit is at the bottom of the turning plate 43, and the medical staff starts the motor 33, which drives the rotating shaft 34 to rotate. The rotating shaft 34 is connected to the rotating ring 313 by threads. The rotating shaft 34 drives the rotating ring 313 to rotate during its rotation. At this time, the second latching tooth 3131 on the rotating ring 313 is engaged with the third latching tooth 361 on the connecting rod 1 36. When the rotating ring 313 rotates, it drives the connecting rod 1 36 to rotate in the direction of the bed body 1. The second protrusion 362 on the connecting rod 1 36 slides in the arc groove 1 311 on the fixed block 1 31. The connecting rod 1 36 pulls the fourth connecting rod 363 and pushes the fifth connecting rod 364 toward the bed body 1. The connecting rod 4 363 plays an auxiliary supporting role. The end of the connecting rod 5 364 away from the connecting rod 1 36 pushes the connecting rod 38 to move in the direction of the bed body 1. The connecting rod 3 38 pulls the connecting rod 2 37 to move synchronously. The connecting rod 3 38 drives the ratchet bar 1 392 on the fixing rod 39 to slide into the limiting track 413, and the ratchet bar 1 392 engages with the ratchet 414. As the swivel 313 continues to rotate in the direction of the fixing block 31, the fixing block 31 is separated from the connecting rod 1 36. At the same time, the fixing rod 39 drives the ratchet bar 1 392 to slide to the end of the limiting track 413 where the ratchet 414 is not provided. At the same time, the guard plate 391 contacts one side of the patient's body, and because the guard plate 391 is a curved surface that conforms to the shape of the human body, the patient's discomfort can be reduced. At this time, the guard plate 391 is completely in contact with the patient's body and can move within a certain range following the movement of the patient's body, without restricting the patient's movement while playing a protective role.

[0041] like Figure 2 and Figure 4-6As shown, when the rotating shaft 34 rotates, it drives the gear 1 35 to rotate, and the gear 1 35 drives the rack 1 42 to move away from the bed body 1, and drives the turning board 43 to move closer to the patient. At this time, the gears 2 435 at both ends of the round rod 433 rotate on the rack 2 412, and drive the bed sheet fixing clamp 434 to rotate synchronously, so that the dirty bed sheet is rolled up on the bed sheet fixing clamp 434 and the round rod 433. When the turning board 43 drives the round rod 433 to move, it synchronously drives the limiting track 413 to slide on the limiting plate 41. At the same time, a section of the bottom of the turning board 43 is horizontally arranged from one side of the patient to enter under the patient. Since the turning board 43 is made of smooth material, the gap between the turning board 43 and the patient is reduced. The friction force enables the turning board 43 to slide under the patient more easily, avoiding discomfort or injury to the patient during the process of changing the bed sheets. Also, because the inner side of the turning board 43 is arc-shaped, when the turning board 43 moves under the patient, the patient's body will be slightly tilted to one side, and there will be no pressure on the other side of the patient's body due to the excessive turning angle. At this time, the gears 435 on both sides rotate to the inclined section of the through groove 411, so that the turning board 43 moves upward synchronously, separating the patient from the bed body 1, making it easier for medical staff to change new bed sheets, making it easier for medical staff to turn the patient over and change bed sheets, and improving the patient's comfort.
