[0001] The utility model relates to the technical field of foldable trays, and more specifically, to a foldable tray. Background Art

[0002] Cardiology, also known as cardiovascular medicine, is a department in hospitals set up to diagnose and treat heart and vascular diseases. The heart and blood vessels supply blood, oxygen and nutrients to various organs throughout the body. Once a disease occurs rapidly, it can cause death in a few minutes if treatment is not timely. Generally, after the patient is diagnosed and treated in the cardiology department, the patient's body is often relatively weak and requires follow-up care to help the patient recover. In the past, nursing trays were used in nursing. Nursing trays are mainly used for the placement of medical equipment. The existing device is not convenient to adjust the horizontal height of the tray, which reduces the comfort of medical staff during work, and the tray of the existing device cannot be freely disassembled, and its applicability is low. In order to solve the above problems, we have launched the following device. Utility Model Content
