Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to an electric bed-chair conversion bed with a shank position, a bed beam and a bed board capable of stretching and retracting in a linkage mode, and is particularly suitable for being used as a sickbed.
Background
For families with small household area, the electric bed-chair conversion bed can be used as a bed and a chair, and is convenient and practical to use. For some leisure areas, an electric bed that can be converted into a comfortable chair is also a good choice.
The hospital ward area is not large, the space is limited, it is difficult to provide comfortable seats for patients, although the existing multifunctional electric sickbed also has the function of lifting the bed surface and lifting the backrest (back bed plate) to enable the patients to lean on, but because the feet of the patients can not land, the patients with weak physical strength, fracture rehabilitation period and the like need to get off the bed to exercise difficultly, the existing method is to enable the patients to sit up first, and then move slowly to sit beside the bed under the assistance of nursing staff, and then the patients with back-up get off the bed to stand and walk.
For patients who can sit up and walk, the long-time bed-lying causes the abnormal rest time and has the complications of falling pneumonia, thrombosis, muscle disuse atrophy and the like, so that an electric bed-chair conversion sickbed which can be comfortably seated and does not occupy more space in a ward can enable the patients to comfortably sit on the chair surface (the hip bed surface) with a backrest and feet, and the patients can conveniently get off the bed to exercise and recover.
The conventional multifunctional electric sickbed also has the functions of sitting up and lowering legs, one mode is that a shank position bed plate is directly lowered to form a chair, the length of the shank position bed plate is about 650mm generally, so that the chair surface is too high from the ground, and the feet of a patient cannot touch the ground, and the other mode is that the shank position bed plate is divided into two folds, but the end-folded bed plate (mattress) after being folded down can only be used as a foot pad, and the feet cannot touch the ground, and the mattress is soft and difficult to stand and get out of the bed. The two multifunctional electric sickbeds only have the function of a chair on the bed. The ideal bed would be converted into a chair: firstly, the cushion can be adjusted to be less than or equal to 450mm above the ground, and feet can land on the ground. And secondly, the folding-down and resetting processes of the bed plate mattress at the shank position in the conversion process can continuously support the shank, so that the falling feeling can not occur, and the mood tension of a patient on the bed can not be caused. And thirdly, there is no blocking component in front of the chair and beside the chair, there is no blocking for the entrance and exit, and it can also be used to place dining table or walking aid frame, which is convenient for the patient to use. In view of the above, the present inventors have made extensive studies and studies to solve the above problems in combination with the application of the above prior art, and as a result, the present inventors have improved the present invention.
