Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a nursing anti-pressure sore auxiliary turning device. Background Art

[0002] Pressure sores, also known as pressure ulcers and bedsores, are caused by long-term pressure on local tissues, resulting in continuous ischemia, hypoxia, and malnutrition, leading to tissue ulceration and necrosis. Currently, for patients who are bedridden for a long time and cannot take care of themselves, the prevention of pressure sores is of vital importance in clinical nursing work. Pressure sores will cause great pain to patients, bring a heavy economic burden to their families, and cause great disadvantages to the patients' recovery. Clinically, in order to prevent the occurrence of pressure sores, it is necessary to change the position of long-term bedridden patients regularly.

[0003] Chinese patent document CN215350098U discloses a device for assisting patients in turning over to prevent pressure sores for critical care nursing, comprising a mattress, two adjustment components and a crank for adjusting the angle of a connecting rod, wherein support plates are fixed to the bottom of both ends of the mattress, and two connecting rods are fixed between the two support plates, a connecting groove is provided at the bottom of the mattress, and a plurality of adjustment belts are installed at equal distances in the connecting groove, and the two adjustment components for adjusting the angles of the two ends of the adjustment belts are respectively installed at the two ends of the two connecting rods, and the utility model designs two adjustment groups on the mattress to drive the angle of the adjustment belt on the mattress to be adjusted without affecting the normal use of the mattress, thereby assisting the patient in turning over, and at the same time, the adjustment belt can be driven to shake through a shaking member, thereby achieving shaking massage of the patient's squeezed skin, improving blood circulation, and reducing the incidence of pressure sores.

[0004] The existing technology has the following problems:

[0005] The turning device uses two adjustment components to turn the patient over, but this form needs to consider the position of the patient on the bed. For example, if the patient is on the outside of the mattress, then when turning the patient over, operating the two adjustment components at this time will either cause the patient's movement to be too large, increasing the patient's pain, or it will be difficult to turn the patient over. It is necessary to adjust the patient's position before turning the patient over. Utility Model Content

[0025] It should be noted that the upper surface of the backing plate 4 is processed into a smooth surface to reduce the friction between the backing plate 4 and the adjustment belt 54 .

[0026] like Figure 2 , Figure 3 As shown, the turning mechanism 3 includes a first motor 31, the lower end of the first motor 31 is fixedly connected to a position near the left side on the first connecting beam between the left and right sides of the bed legs 2, the output end of the first motor 31 is fixedly connected to a transmission rod 32, the outer side of the transmission rod 32 is fixedly connected to a plurality of uniformly distributed first bevel gears 33, the position between the mechanism plate 6 and the first connecting beam is rotatably connected to a plurality of linearly distributed screws 34, the outer walls of the plurality of screws 34 are fixedly connected to a second bevel gear 38 at a position away from the mechanism plate 6, the right side of the second bevel gear 38 is meshed and connected with a side of the first bevel gear 33 close to the mechanism plate 6, the outer sides of the plurality of screws 34 are threadedly connected to a moving seat 35, the upper side of the bed frame 1 is rotatably connected to a bed board 36 at a boss near the middle of the left and right sides, a push rod 37 is rotatably connected between the upper side of the moving seat 35 and the side of the lower side of the bed board 36 away from the mechanism plate 6, and the lower side of the pad 4 is fixedly connected to the upper side of the bed board 36.

[0027] It should be noted that the first motor 31 drives the transmission rod 32 to rotate, and when the transmission rod 32 rotates, it drives the first bevel gear 33 to rotate, and when the first bevel gear 33 rotates, it drives the second bevel gear 38 to rotate, and when the second bevel gear 38 rotates, it drives the screw 34 to rotate, and when the screw 34 rotates, the moving seat 35 moves back and forth, and when the moving seat 35 moves, it causes the push rod 37 to push or pull the bed board 36 away from one side of the mechanism plate 6, causing the bed board 36 to rotate.

[0028] like Figure 2 , Figure 4As shown, the adjustment mechanism 5 includes a steering rod 51, the left and right sides of which are rotatably connected to the front and rear sides of the bed frame 1 near the bosses on the left and right sides, and the steering rod 51 is provided with two symmetrically distributed upper and lower parts on the front and rear sides of the bed frame 1, and the upper surface of the left second connecting beam between the front and rear of the bed legs 2 is fixedly connected with two second motors 52 symmetrically distributed front and back, and the output ends of the two second motors 52 are fixedly connected with a winding roller 53, and the outer side of the winding roller 53 is wound with an adjustment belt 54, and the steering rod 51, the bed frame 1 and the pad 4 are all on the inner side of the adjustment belt 54.

[0029] It should be noted that the second motor 52 drives the winding roller 53 to rotate, and when the winding roller 53 rotates, it drives the adjustment belt 54 to be gathered or released on the two winding rollers 53, so as to achieve the purpose of moving the adjustment belt 54 on the upper side of the pad 4 forward and backward, and the steering rod 51 is used to turn the direction of the adjustment belt 54.

[0030] like Figure 4 As shown, the adjustment strap 54 is made of canvas.

[0031] It should be noted that the canvas can increase the strength of the adjustment belt 54 and extend the service life of the adjustment belt 54. At the same time, the canvas is relatively rough and can increase the friction between the canvas and the upper mattress to drive the mattress to move forward and backward, thereby allowing the patient to move forward and backward.

When the screw 34 rotates, the moving seat 35 moves back and forth. When the moving seat 35 moves, the push rod 37 pushes or pulls the bed board 36 away from one side of the mechanism plate 6, causing the bed board 36 to rotate. The moving seat 35 is driven to move by the first motor 31, and then the push rod 37 drives the bed board 36 to rotate, causing the bed board 36 to push the patient to turn over. The motor operation avoids the problem of cumbersome operation in the form of shaking hands, greatly reduces the labor intensity of medical staff, and makes the work of medical staff easier.
