Simplified the traditional priocess of the bladder diary recording. With the help of the technical advantages of the eCoaster Bluetooth scale and the BaDa Diary APP, we have introduced a minimalist operation method to the operation of the bladder diary. Patients only need to use adult absorbent pads and do not need to change any daily habits to complete the weighing and recording operations of the bladder diary in a very secret way. This unprecedented convenience can offset the fear of difficulty of most patients and allow urination. The diary record can be continuously carried out throughout the treatment and rehabilitation training process, and timely provide consultant with detailed treatment reference datas, improve the treatment effect and shorten the treatment cycle.
