Description

Technical Field

[0001] This invention relates to the field of intensive care unit technology, and in particular to a multifunctional intensive care unit nursing bed. Background Technology

[0002] In the intensive care unit (ICU) setting, patients' conditions are critical and complex, and the functional requirements for nursing beds far exceed those of ordinary wards.

[0003] In practical applications, existing equipment for hospital beds often only supports overall height adjustment or simple back tilting, failing to achieve precise and independent adjustment of multiple body parts (such as head, back, waist, and legs). Critically ill patients, due to their conditions (such as multiple injuries, neurological dysfunction, and respiratory and circulatory failure), frequently require special positions (such as prone ventilation, stepped sputum clearance positions, and joint function positioning), which are difficult to meet with single adjustments. This increases the risk of complications such as pressure sores and respiratory depression, hindering practical application and operation. Summary of the Invention

[0004] One objective of this invention is to provide a multifunctional intensive care unit nursing bed.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a multifunctional intensive care unit nursing bed, comprising a housing: an adjustment structure is provided on the upper part of the housing, the adjustment structure comprising a central plate, a first side plate, a second side plate and a connecting plate;
