Kidney biopsy is an invasive procedure. To prevent internal bleeding after kidney biopsy, local pressure is applied to the puncture site using sandbags. However, in the process of sand bag pressurization, patients and their families may need to pay attention to the sandbag pressurization, which may interfere with their work and rest or cause discomfort and back pain due to the restriction of activities for a period of time. Moreover, the nursing staff may have to increase the frequency of care. After considering the comfort of patients and economic benefits, the "Safe Kidney Protection Bag" was designed. The long cloth strips are suitable for any waist size, and the pockets can be packed into the sandbags as auxiliary materials for appropriate compression to stop bleeding and prevent complications after the kidney biopsy procedure. This is an innovative product with simple, convenient, and reusable features. In the future, the expansion of other procedures that require sandbags will surely reduce the nursing care load and increase patient satisfaction.
