Description

Technical Field

[0001] The utility model relates to the field of medical auxiliary equipment, in particular to a turning-over auxiliary device for preventing and treating bedsores of bedridden patients. Background Art

[0002] The pressure sore turning device is a medical device that is mainly used to help patients with limited mobility or long-term bedridden patients turn over to prevent the occurrence of pressure sores (also known as bedsores). Pressure sores are caused by prolonged pressure on a part of the body, resulting in poor blood circulation and damage to the skin and subcutaneous tissue.

[0003] Traditional turning methods usually require nursing staff to manually help patients do it, which not only consumes a lot of manpower and time, but may also cause patient injuries due to improper operation. Therefore, the development and use of pressure sore turning devices are particularly important.

[0004] In view of this, Chinese invention patent application 201510824278.5 discloses a pneumatic turning bed, which is composed of a pneumatic turntable, a curved central axis, a lower bed, an upper bed, a connecting fixed groove, etc. The pneumatic turntable includes a turntable fixing block and a turntable rotating block, and its outer shell is a turntable shell, on which there are reverse air supply pipes and forward air supply pipes. If the reverse air supply pipe supplies air, the inner turntable rotating block and the curved central axis, the lower bed, and the upper bed rotate 180° counterclockwise; on the contrary, if the forward air supply pipe supplies air, the inner turntable rotating block and the curved central axis, the lower bed, and the upper bed rotate 180° clockwise. When the air supply is repeatedly changed, the lower bed and the upper bed rotate and change positions repeatedly, which can realize that long-term bedridden patients who are conscious and can move their hands can turn the pneumatic switch handle at any time when there is no attendant on duty, so as to realize free turning over by pneumatic without touching electrical appliances.

[0005] However, although the above structure can assist bedridden patients to turn over, the turning process is too painful for the patients. First, the distance between the upper and lower beds is greater than the patient's body thickness, and the patient's body will inevitably be bumped during the turning process. Considering that bedridden patients have poor physical fitness, they cannot withstand such turning over at all, and it is difficult for them to bear the risk of injury caused by turning over; secondly, when the upper and lower beds are rotated and exchanged, the patient's face is facing downward, which can easily cause suffocation; finally, the existence of the upper and lower bed boards will give the patient a strong sense of spatial restraint, which can easily cause discomfort to the patient. Utility Model Content

[0006] The utility model aims to provide a turning-over assisting device for preventing and treating pressure sores in bedridden patients. On the one hand, it can assist in changing the patient's body position to prevent bedridden patients from maintaining the same posture for a long time, reduce the continuous effect of pressure on the skin, and thus play a role in preventing pressure sores. On the other hand, it can control the turning angle of bedridden patients to facilitate nursing staff to carry out efficient nursing, promote the healing of pressure sores, and thus solve the technical problems described in the background technology.

[0007] In order to achieve the above object, the utility model first discloses a technical solution:

[0008] A turning-over assisting device for preventing and treating bedsores of bedridden patients comprises a bed frame and a bed board arranged on the bed frame, the key point of which is that the board edges on the left and right sides of the bed board are recessed in sections along the width direction to form a plurality of open mounting openings, a turning-over assisting rod is hinged in each of the mounting openings, and the turning-over assisting rods on the same side are mechanically linked with an adjusting mechanism respectively to achieve synchronous control of the pitch angle of the turning-over assisting rods on the same side, thereby assisting bedridden patients to passively turn over.

[0009] Furthermore, the adjustment mechanism includes a slide arranged in the bed frame along the width direction, a movable frame is provided on the slide, a plurality of connecting arms are hinged on the movable frame, and the ends of the connecting arms are hinged one by one to the turning over auxiliary rod on the same side.

[0010] Furthermore, a lead screw adapted to the movable frame is also arranged in the slide, and the end of the lead screw extends out of the bed frame and is used to receive rotational power.

[0011] Furthermore, the end of the lead screw is connected to a hand wheel via a worm gear transmission assembly.

[0012] Furthermore, the bed board adopts a hollow structure, and its internal cavity serves as an air flow channel adapted to its contour, and an air outlet of the air flow channel is also provided on the upper surface of the bed board.

[0013] Furthermore, an air inlet of the air flow channel is provided on the lower surface of the bed board, and the air inlet is communicated with the air pump through an air inlet pipeline.

[0014] Furthermore, an air guide structure with an adjustable blowing angle is provided in the air outlet.
