Technical Field

[0001] The utility model relates specifically to the field of nursing beds, in particular to a lying-sitting conversion nursing bed. Background Art

[0002] Nursing beds are generally powered beds, which are divided into electric or manual nursing beds. They are designed according to the patient's bedridden lifestyle and treatment needs, so that family members can accompany them. They have multiple nursing functions and operation buttons, and use insulated and safe beds, such as weight monitoring, back-lifting for meals, timed turning over alarm, prevention of bedsores, negative pressure urine suction bedwetting alarm, mobile transportation, rest, rehabilitation, infusion and medication, related prompts and other functions, which can prevent patients from falling out of bed. Rehabilitation nursing beds can be used alone or in conjunction with treatment or rehabilitation equipment.

[0003] When the patient sits on the bed with the back raised, the patient has to lie flat on the bed with the back raised. This makes the patient's sitting posture uncomfortable.
