Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a weighing device and a weighing bed. Background Art

[0002] When treating bedridden patients, such as critically ill patients, it is generally necessary to determine the dosage of medication and various nutritional supplements based on the patient's weight. However, most critically ill patients are bedridden and cannot move independently or cannot move a large range due to the limitations of treatment equipment. They cannot leave the bed to go to the weighing room for measurement and need to be measured in the ward, so it is difficult to complete the weighing task. At the same time, it is also difficult for patients who can move independently to complete standing weighing without assistance.

[0003] In addition, if it is necessary to collect the patient's weight regularly or under instructions for background analysis, there is a lack of hardware support to implement the function.

[0004] In addition, current weighing devices are difficult to disassemble and assemble. Once damaged, the entire device will be scrapped. The cost is high and it is not suitable for large-scale application scenarios.

[0005] Therefore, those skilled in the art have devoted themselves to studying a weighing method and device for weighing bedridden patients. Utility Model Content
