Description

Technical Field

[0001] This invention relates to a multifunctional nursing bed. Background Technology

[0002] Long-term bedridden patients, disabled elderly, and postoperative recovery patients require frequent repositioning, assisted bowel movements, and pressure ulcer prevention. Existing nursing beds generally suffer from problems such as limited functionality, redundant structure, laborious operation, easy slippage during turning, poor sealing of the defecation port, lack of overall height adjustment, and high nursing intensity, failing to meet the integrated comfort needs of home and clinical care. Therefore, there is an urgent need for a highly integrated, stable, safe, reliable, and easy-to-operate multifunctional nursing bed.

[0003] Traditional nursing beds can only combine a few existing functions, which cannot meet the personalized needs of users or guarantee comfort. Therefore, they need to be assigned to each patient, which not only increases the cost of using the nursing bed, but also increases the nursing costs of hospitals and nursing homes.
