Hospital Medical airtight Sliding Door The medical automatic door is a door that is generally installed in the operating room or the ICU ward for the medical staff to push in and out of the hospital bed. The medical automatic door has the function of inductive opening and safety anti-pinch. The medical staff only needs to extend the foot into the light control foot sensing box next to the entrance, and the door will automatically close.
After a period of time, the door will automatically close after the cart and medical staff have fully entered. If someone or a cart is next to the door leaf, the door will not close to provide a safe anti-pinch. In addition, the door frame of the medical automatic door is made of sealed profile, which has the characteristics of high air tightness; the light control foot sensing is adopted for the entrance and exit, so that the medical staff can open the door [without contact", which can effectively isolate the bacteria and personnel.
