Abstract
Description
Technical Field
[0001] The present invention relates to the field of medical device auxiliary equipment, and in particular to a movable supporting device for an electrocardiograph. Background Art
[0002] In modern medical diagnostics, electrocardiograms (ECGs), a fundamental and crucial piece of testing equipment, are widely used in medical institutions at all levels. From cardiovascular clinics and inpatient wards in large general hospitals to community health centers, ECG testing is a routine medical examination. However, existing ECG support devices present numerous issues, significantly hindering practical medical operations.
[0003] In traditional wards, beds are densely distributed and space is relatively limited. Common ECG machine support devices are often large and lack mobility. Medical staff performing ECG tests on patients in different beds need to spend considerable time pushing the heavy support device through narrow aisles. Sometimes, due to space constraints, it's difficult to even get close to the patient's bed, severely impacting testing efficiency. For example, in some older wards, where the wards are relatively small, the space left for the support device to move after multiple beds and related medical equipment are placed is extremely limited. Conventional four-wheeled fixed support devices struggle to smoothly turn and move to the appropriate position.
[0004] In emergency situations, time is of the essence. Existing support devices lack fast, flexible movement and height adjustment mechanisms, making them unable to quickly adapt to the complex environments of different emergency scenes. For example, in the cramped cabin of an ambulance, a crowded elevator, or outdoors where a patient is experiencing an emergency, traditional support devices are difficult to quickly deploy and adjust to the appropriate height. This prevents timely and accurate electrocardiogram (ECG) testing, potentially delaying the diagnosis and treatment of the patient's condition.
[0005] In addition, different types of ECG machines vary greatly in size and shape, and existing support devices are mostly fixed in design, making it difficult to achieve stable and adaptive placement and fixation of various types of ECG machines. Some support devices can only accommodate ECG machines of a specific size. When faced with smaller or larger ECG machines, they are prone to unstable placement, which not only affects the normal operation of the equipment during the test, but may also cause inaccurate test results due to shaking of the equipment. At the same time, these support devices generally lack reasonable storage designs for related accessories such as lead wires, electrodes, and medical consumables such as alcohol cotton. During the test process, the lead wires are often tangled and medical staff need to spend extra time to organize them, which not only increases the workload, but may also affect the accuracy of the test results due to incorrect lead wire connections.
[0006] In summary, the existing electrocardiograph support device has obvious deficiencies in terms of mobility, adaptability, and storage function. There is an urgent need for a newly designed movable support device to meet the needs of efficient and convenient use in diverse medical scenarios. Summary of the Invention
