Description

Technical Field

[0001] The utility model belongs to the field of medical technology, and particularly relates to a foldable hospital bed. Background Art

[0002] The beds used by patients or severely disabled people during hospitalization for recuperation and rehabilitation include ordinary beds and multifunctional back-lifting beds. Hospital beds can also be called patient beds, medical beds, multifunctional nursing beds, etc. They are beds used by patients during recuperation and rehabilitation treatment. They are mainly used in major hospitals, township health centers, community health service centers, rehabilitation institutions, etc.

[0003] For those who have leg diseases and are bedridden for a long time or have undergone surgery in a passive position, a soothing leg massage is necessary. By promoting blood circulation in the patient's legs and increasing the oxygen content in the limbs, it can prevent muscle atrophy and weakening, and help resolve diseases caused by poor blood circulation.

[0004] Patent No. CN213311378U discloses a massage bed that can be raised and lowered, Patent No. CN205094827U discloses a massage bed that prevents slipping, and Patent No. CN218529100U discloses a bed with massage function, all of which use massage equipment to replace a part of the bed board to massage the back of a patient lying flat. Since most beds are padded with mattresses, mattress pads, etc., this will affect the massage effect. In order to achieve a good massage effect, part of the mattress and mattress pad may be removed, which is more troublesome to operate. If a thinner mattress and mattress pad are always used in order to achieve a good massage effect, the patient will sleep on a harder bed most of the time when massage is not needed. The patient himself is in an extremely sensitive state of physical discomfort, so the discomfort will be more obvious, affecting recovery.

[0005] Therefore, a hospital bed with massage facilities is needed to balance the above two problems. Utility Model Content
