- All of the devices we use in our lab have been shown to be medically safe, and are commonly used in sex research around the world. The vaginal photoplethysmograph is the most common medical tool for measuring vaginal arousal, and been used in research for over 40 years. This small, tampon shaped device measures blood flow to the vagina via detecting changes in light absorbance; see here for more information.
- For the sake of hygiene and safety, we properly sterilize our research instruments after each use. All of our research assistants who are trained in the use of our equipment are also trained in our sterilization procedure.
- After the devices have been used, they are thoroughly washed in antimicrobial soap and warm water. Next, they are disinfected using CidexOPA. Cidex is an orthodox-phthalaldehyde solution that has been designated by the U. S. Food and Drug Administration as a “high level disinfectant” appropriate for the disinfection of reusable medical devices that cannot be subjected to heat sterilization. It is commonly used to sterilize gynecologic health instruments such as vaginal ultrasounds. Cidex is known to be effective at killing a broad array of bacteria, mycobacteria, viruses and fungi, including the herpes simplex virus, HIV, and C. albicans (the pathogen that causes yeast infections). We test this solution on a weekly basis to ensure it is strong enough to achieve the necessary high level of disinfecting power.
- The final step in preparing the equipment for its next use is to rinse it thoroughly with warm water to remove all disinfectant solution, dry the equipment with medical gauze, and seal it in a plastic bag. Our researcher wear gloves and lab coats during participant testing and during the cleaning procedure in order to maintain a high level of sanitation. In addition, the laboratory surfaces (countertops, exam table) and all non-invasive equipment (e.g., clipboards, pens) are wiped down with a sterilizing bleach solution following each experimental session.
- We keep a log for each use to record which experimenter sterilized the devices and exactly how long the devices soaked in the disinfectant solution. This helps us keep track of our sterilization procedures and ensure that our equipment is safe to use at any given time.
- We are subject to routine inspection through the UNCC Institutional Biological Safety Committee (IBC), and have been approved as a Biosafety Level 2 Facility.
