Description

Technical Field

[0001] This utility model relates to the field of medical bed technology, specifically to an easily adjustable medical bed. Background Technology

[0002] Adjustable medical beds are widely used in hospitals, nursing homes, geriatric care facilities, and home care environments. Their main function is to provide comfortable, effective, and adjustable support to help patients or the elderly maintain optimal posture, reduce physical burden, facilitate caregiver operations, and improve the patient's quality of life. With the development of medical technology, the design and technology of medical beds are constantly innovating to meet the diverse needs of patients.

[0003] Patent specification CN 221770626 U discloses an easily adjustable medical bed. It includes two headboards and a bed board located between them. Each headboard has a sliding groove on its front and rear sides, with a slider connecting the groove to one side of the bed board. A connecting plate is fixedly connected to the bottom of one side of the headboard. This invention relates to the field of medical bed technology. This easily adjustable medical bed allows for convenient height adjustment by pushing the bed board upwards with a push plate, ensuring bed board stability and making it easier for patients to get in and out of bed. It also eliminates the need for caregivers to bend over to assist patients. Simultaneously, a screen and screen rod extend from the screen frame to protect both sides of the bed, effectively shielding the patient. The screen rod and screen can also retract into the screen frame, no longer obstructing the sides of the bed, further facilitating patient access.

[0004] However, during the implementation of the relevant technology, the above-mentioned adjustable medical bed has the following problems: when using the device, there are no corresponding guardrails on both sides of the bed board, and patients are prone to falling off. At the same time, it is inconvenient to adjust the height of the medical bed to facilitate nursing care and avoid nurses having to bend over to provide care. Therefore, we have proposed an adjustable medical bed. Utility Model Content
