Harness the Power of Your Natural Immune System with HOCL Products

10 PER BOX MaskIT Diagnostic Guardian™

Item Number: DG-1235-10

Why MaskIT?

Endoscopy is a critical part of the ENT examination which brings the doctor to within 20 inches of the patient. During ENT exams we increase the risk of exposure to infectious particles purely by examining an unprotected source. Endoscopy stimulates the nose and throat to possibly create an unpredictable and spontaneous cough, sneeze or gag which can expel infectious particles.

These events may be rare, but exposes everyone and the room to unpredictable infectious load. It is not practical nor fiscally responsible to test every patient for every illness prior to scoping. Asymptomatic false negative Covid patients exist; hence universal precautions are critical and have yet to be fully established.

MaskIT Diagnostic Guardian provides critical source protection to examiner, reduces exposure to the room and everyone in the room. 

10 masks per box


How It Works

The MaskIT Diagnostic Guardian™ is placed on patients prior to endoscopy procedures. After securing the mask to properly fit the patient, endoscopes can be inserted through the hole in the seal. The patient's nasal area can easily be visualized through the clear plastic fitting.

What has COVID-19 taught us?

Scopes have been found to create aerosols consistent with speaking and breathing unless the patient has a spontaneous sneeze, cough, gag or cry.

Are you or your staff willing to take this risk?

  1. Be prepared by having reserve PPE
  2. Use universal precautions on ALL sick patients with any head and neck illness
  3. During a novel pandemic use universal precautions on all patients (sick or not) 

Inserting Endoscopy Through Mask

The use of extra PPE like the MaskIT Diagnostic Guardian™ during the covid crisis has resulted in the AMA approving the code 99072. This code has begun to see payment by some carriers.
