Description

Technical Field

[0001] The invention relates to the technical field of medical nursing equipment, in particular to a back massage regulating device for a nursing bed. Background Art

[0002] Nursing bed is a medical device designed for long-term bedridden patients. It not only provides basic sleeping functions, but also integrates a variety of nursing functions and operation buttons to meet the various needs of patients. It is widely used in medical institutions such as hospitals, clinics, nursing homes, and the homes of patients who need home care and rehabilitation, providing patients with a more comfortable and safe bedridden environment, while also improving the work efficiency of medical staff.

[0003] Massage care is an ancient and effective treatment method. It stimulates the skin, muscles and deep tissues through the application of manipulation based on the physiological structure and function of the human body. This stimulation can promote blood circulation, help oxygen and nutrients to be better transported to every corner of the body, and accelerate the discharge of metabolic waste. Massage can also reduce muscle tension, relieve pain, and improve joint flexibility and range of motion. For patients who have been bedridden for a long time, massage care can effectively relieve muscle fatigue and stiffness, and improve muscle flexibility and strength. Massage can also promote blood circulation in patients and prevent the occurrence of complications such as bedsores. Traditional massage equipment is usually an independent and fixed structure. If bedridden patients need massage care, they often need to place the massage equipment on the nursing bed and then massage. However, this massage care method has the disadvantages that the massage equipment does not match the nursing bed, and there is a height difference between the massage equipment and the surface of the nursing bed, which is not conducive to the effective massage of the patient's back, and it is not easy to adjust the position of the massage area.
