Introduction: Extracorporeal shock wave lithotripsy (ESWL) is a standard treatment method in the clinical treatment of urinary calculi. When the probe of lithotripter is in direct contact with the human body, a semi-liquid gel is usually used as the coupling material between the skin and the probe. If the gel on the probe has contact with the wound on the skin, it might contaminate the probe and spread body fluid and blood between the patients undergoing ESWL. This study aimed to investigate the isolative efficacy of icPad in blocking the permeation of fine particles such as bacteria and viruses.

Materials and Methods: The experiment was divided into three groups: experimental group, control group and blank group. The experimental group received ESWL, and the frequency and output energy of shock wave was set according to clinical guideline. The fluorescent dye was used as simulating pollutants such as blood and viruses. Qualitative and quantitative analysis were applied for analyzing the degree of the fluorescent dye distributed on the probe surface. In the qualitative analysis part of the control group, icPad was cut into slices, and placed the section under a microscope to measure the longitudinal permeation. In the quantitative analysis part, we measured the fluorescence intensity of icPad with a fluorescence spectrometer. The experiments of each group were repeated three times.

Results: Qualitative and quantitative analysis results confirmed that icPad has an isolation effect on pollutants.

Conclusions: This experimental and observational study is the first time to investigate the isolation efficacy of icPad during ESWL. Comparing to semi-liquid gel, using icPad as the coupling medium can effectively isolate the direct contact between the probe and the patient’s skin and to block the permeation of fine pollutants.
