Description

Technical Field

[0001] The utility model belongs to the technical field of medical facilities, in particular to an anti-pressure sore nursing bed. Background Art

[0002] For patients with limited mobility and the elderly, long-term bed rest can easily cause pressure sores on the local skin under pressure. To avoid the occurrence of pressure sores, caregivers need to frequently turn the patient or the elderly over so that the local compressed skin is fully exposed to the air, thereby keeping the local skin dry and clean and relieving skin pressure.

[0003] At present, turning over of patients or elderly people mainly depends on nursing staff to push, pull, and drag them hard, and then put a support such as a pillow behind them. However, this turning operation is time-consuming and laborious. On the one hand, it increases the labor intensity of nursing staff; on the other hand, excessive force can easily cause injuries to patients or elderly people, increasing the pain of patients. Especially in the hot summer, it takes 1-2 hours to turn over and over, and the frequency of turning over care is higher, which greatly increases the labor intensity of medical staff.

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] In the description of the present invention, it should be understood that terms such as "upper", "lower", "axial", "top", "middle", "length", "inside", "all around" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limitations on the present invention.

[0029] At present, in order to avoid pressure sores, long-term bedridden patients or elderly people mainly rely on nursing staff to push, pull, and drag hard, and then put a support, such as a pillow, behind their backs. However, this turning operation is time-consuming and laborious. On the one hand, it increases the labor intensity of nursing staff; on the other hand, excessive force can easily cause injuries to patients or elderly people, increasing the pain of patients. Especially in the hotter summer, it takes 1-2 hours to turn over and over, and the frequency of turning over care is higher, which greatly increases the labor intensity of medical staff. Based on this, this embodiment provides an anti-pressure sore nursing bed.

[0030] See also Figure 1-Figure 2 As shown, this embodiment provides an anti-pressure sore nursing bed, which includes a head support part 100, an upper body support part 200 and a lower body support part 300 in sequence along the length direction of the nursing bed. The head support part 100, the upper body support part 200 and the lower body support part 300 are all installed on a bed frame 400.

[0031] In this implementation, see Figure 3 and Figure 4 As shown, the upper body support part 200 is divided into two halves along the centerline direction of the nursing bed, namely, a first half support part 1 and a second half support part 2. Specifically, the first half support part 1 includes a plurality of first bed boards 101 arranged in an array and two first longitudinal support rods 102, and the plurality of first bed boards 101 are fixedly mounted on the two first longitudinal support rods 102. The first longitudinal support rods 102 are along the length direction of the nursing bed.

[0032] The second half support portion 2 adopts the same structure as the first half support portion 1 , including a plurality of second bed boards 201 arranged in an array and two second longitudinal support rods 202 , and the plurality of second bed boards 201 are fixedly mounted on the two second longitudinal support rods 202 .

[0033] The bed frame 400 includes a supporting longitudinal beam 4 arranged along the central axis of the nursing bed. The inner end of the first half support part 1 and the inner end of the second half support part 2 are hinged to the supporting longitudinal beam 4 through a hinge, so that the first half support part 1 and the second half support part 2 can be flipped inward around the hinge point.

[0034] In order to realize driving the first half support part 1 and the second half support part 2 to flip, a driving mechanism 3 is also designed. Specifically, the first half support part 1 also includes a first transverse sliding groove plate 103, which is perpendicular to the first longitudinal support rod 102 and fixed to the lower surface of the first longitudinal support rod 102. The second half support part 2 also includes a second transverse sliding groove plate 203, which is perpendicular to the second longitudinal support rod 202 and fixed to the lower surface of the second longitudinal support rod 202.

[0035] The driving mechanism 3 includes a screw rod 301, a slider 302, a first driving arm 303 and a second driving arm 304. The screw rod 301 is arranged along the width direction of the nursing bed and is rotatably mounted on the bed frame 400 below the upper body support part 200 through a shaft seat 305. The slider 302 is threadedly connected to the screw rod 301. When the screw rod 301 rotates, the slider 302 can slide in the first direction or the second direction. The first direction and the second direction are opposite.

[0036] One end of the first driving arm 303 and one end of the second driving arm 304 are both hinged to the slider 302, the other end of the first driving arm 303 slides in cooperation with the slide groove of the first horizontal slide groove plate 103, and the other end of the second driving arm 304 slides in cooperation with the slide groove of the second horizontal slide groove plate 203.

[0037] In a preferred implementation of the present embodiment, crank handles 306 for driving the screw rod 301 to rotate are fixedly mounted at both ends of the screw rod 301, so that the patient can be turned over from both sides of the bed.

[0038] like Figure 3As shown, a possible operation mode of this embodiment is: when the slider 302 is in the middle position of the screw rod 301, the first half support part 1 and the second half support part 2 remain flush, and the patient is in a natural supine position. When it is necessary to assist the patient to turn over, the crank 306 is turned, the slider 302 slides in the first direction, and the first driving arm 303 can gradually lift the first half support part 1, and the patient turns over to the second direction. At this time, the second driving arm 304 is close to one end of the second horizontal sliding groove plate 203, and can slide along the sliding groove of the second horizontal sliding groove plate 203 in the first direction, so that the second half support part 2 does not turn over. Subsequently, to turn the patient to the other side, it is only necessary to reversely turn the crank 306, the slider 302 slides in the second direction, and the first half support part 1 slowly descends. When the slider 302 slides to the middle position of the screw rod 301, the first half support part 1 remains flush with the bed surface, and the patient remains in a supine position. The crank 306 is continuously rotated, and the second half support portion 2 can be gradually lifted up by the second driving arm 304, and the patient can be turned over to the first direction. At this time, the first driving arm 303 is close to one end of the first transverse sliding groove plate 103, and can slide along the sliding groove of the first transverse sliding groove plate 103 to the second direction, so that the first half support portion 1 will not be turned over.

[0039] In summary, this embodiment controls the slider 302 to slide in different directions through the screw rod 301, thereby controlling the first half support part 1 or the second half support part 2 to flip, thereby assisting the patient to turn over in different directions, and has the advantages of simple structure and easy operation.
