Objective To design a funnel-type multifunctional stone collector with simple operation, convenient use, sanitation and satisfactory stone collection, so as to improve the rate of stone examination in patients with urinary calculi. Methods The funnel type multifunctional urinary stone collector was developed and applied in clinic. From June 2018 to December, 146 cases of urinary calculi surgery patients were selected in our hospital, all patients were randomly divided into experimental group and control group, each group with 73 cases. Collection time, stones analysis and satisfaction rate, the medical personnel and their families, the incidence of urine pollution between the two groups were compared, and the efficacy of the application was evaluated. Results ①Technical features: the collector was multi-functional and integrated, integrating funnel and collecting cylinder. The handle, funnel and extended wing were formed in one, and the holder, filter and collecting cylinder were formed in one. The funnel and collection tube could be disassembled, and the funnel could be used as a urine container after the lid was closed. The two sides of the funnel were provided with extended wings, which could be placed on the dirt bucket to collect intraoperative drainage and flushing liquid samples. Clamps were set on both sides of the collection tube, which could be directly clamped at the exit of the drainage bag to collect stone specimens. After the cover was closed, the collection tube could be directly used for sending specimens for inspection. ② The number of stone collection, the rate of stone analysis submission and the satisfaction of medical care and family members in the experimental group were significantly higher than those in the control group(P<0.05), and the incidence of urine contamination and the time of stone collection were significantly lower than those in the control group(P<0.05). Conclusions The funnel-type multifunctional stone collector is reasonable in design, multi-purpose, convenient and sanitary in use, convenient, simple and satisfactory in collecting stones. It is suitable for the collection of stone specimens in all patients with urinary calculi and can improve the rate of examination of stone specimens in patients with urinary calculi.
