SurgiTel’s Implementation of PPE with Loupes and LED Headlights

By improving the design of full-face shield (patent-pending) and universal mounting clip with co-axial extenders (patent pending), SurgiTel can provide PPE with loupes and headlights in three different combinations (Figure 1):

  1. Placing headlight attached to loupes behind the face shield. For this case, thick headband foam provides the necessary space. Reduced brightness on the target may occur due to the reflection by the inner surface of the face shield.
  2. Placing headlight attached to Loupes through the hole of the face shield. In this case, the headlight is exposed to aerosols, but the heat of the headlight can kill viruses.
  3. Attaching headlight to the face shield with SurgiTel’s universal mounting clip. May use the co-axial extender for the best adjustability.

PPE Recommended by The Centers for Disease Control and Prevention (CDC)

The coronavirus COVID-19 mainly spreads from person to person. When infected persons cough or sneeze, they send droplets or aerosols containing the virus into the air. Healthy persons can breathe in those droplets or aerosols. You may also catch the virus if you touch contaminated surfaces or objects and then touch your mouth, nose, or eyes without washing your hands. Figure 2 shows the transmission routes of the virus. It is noted that the virus can live for hours to days on surfaces such as countertops and doorknobs. How long depends on the material the surface is made from (Figure 3).

To stop spreading the virus by aerosols, the Centers for Disease Control and Prevention (CDC) has provided guidance for healthcare professionals (HCP) on using Personal Protective Equipment (PPE).

Earlier the CDC recommended a mask or respirator, gown, and goggle or face shield (Figure 4a). CDC’s newest recommendation changed “goggles or face shield” to “disposable full-face shield” and “mask or respirator” to “respirator” (Figure 4b).1 (Note that N95 or equivalent face masks are considered respirators.)

Questions and Answers

Question #1: Will SurgiTel offer loupes with goggles?
Answer: SurgiTel investigated various goggles for loupes. There are two issues. Goggles do not allow good loupe ergonomics and they create fogging problems. If a full-face shield is used, goggles are not necessary. With face shields, aerosols cannot reach loupes, face masks, and eyes.

Question #2: Will SurgiTel offer a flip-up style face shield?
Answer: Flip-up face shields design cannot stop aerosols reaching your loupes and face because they have a large opening at the top. SurgiTel will continue to investigate various design options. Currently, we recommend full-face shields that do not flip-up.

Question #3: When I wear a mask, I have a fogging problem with my loupes/face-shield. How can I eliminate this problem?
Answer: First you should select a proper style of N95. If the N95 mask is properly fitted, the fogging problem will be eliminated. The CDC and ADA provide fitting & testing instructions.1, 4 If your mask is a non-respiratory mask, you can add band-aids at the top edges of your mask (Figure 5).

Question #4: Can we use UV light to disinfect loupes?
Answer: You can use UV light to disinfect loupes if the disinfecting equipment was tested as infection control equipment, but we have not tested any specific UV disinfecting equipment on loupes.

Question #5: Can hand sanitizer with high alcohol content be used to disinfect loupes and light cables?
Answer: CR Foundation tests showed that hand sanitizers with high alcohol content is very effective in killing viruses.5, 6 Our tests showed that hand sanitizers with “Isopropanol” degrades the glue used for mounting TTL loupes. It is noted that hand sanitizers with “ethyl alcohol (ethanol)” can damage loupes.
