Technical Field

[0001] This utility model belongs to the field of medical device technology, specifically relating to a dressing change cart. Background Technology

[0002] In modern medical institutions, dressing carts and stretchers are two commonly used medical devices. Dressing carts are mainly used to store and move medical instruments, medicines, and dressing supplies, facilitating wound care and medication changes by medical staff in wards or operating rooms. Existing dressing carts are usually fixed in structure, have limited functionality, lack flexibility, and cannot meet the diverse needs of different medical scenarios.

[0003] On the other hand, stretchers, as portable transport devices, are used to move patients from one location to another, such as from a ward to an operating room or ambulance. However, traditional stretchers are designed with the patient's load-bearing and mobility in mind, lacking the function of storing and handling medical supplies, which limits their application in medical procedures such as dressing changes.

[0004] As the demands for efficiency and versatility of equipment in the medical environment increase, existing dressing carts and stretchers need to be configured separately, leading to redundant investment of medical resources and wasted space. Furthermore, when medical staff need to perform patient transfers and wound care simultaneously, they must frequently change equipment, increasing the complexity of operations and their workload.

[0005] Therefore, there is an urgent need for a multi-purpose medical vehicle that can function as both a dressing cart and a stretcher, in order to improve the utilization rate of medical equipment, simplify the operating procedures of medical staff, and meet the needs of modern medical institutions for efficient and flexible equipment.
