Protection requirements: wear goggles/protective face screen, medical protective clothing, shoe covers, gloves. Conditions, can set up a negative pressure isolation room for treatment of seriously ill patients, should meet the "hospital negative pressure isolation room environmental control requirements" (GB/T35428-2017) DB11/663-2009 "Negative Pressure Isolation Room Construction Configuration of the Basic Requirements", set up a double-door interlocking buffer room and transfer window, the buffer room for the potentially contaminated area, but also as a protective gear to wear off with. If you do not have the conditions for setting up a negative pressure isolation ward, you should maximize the ventilation requirements of the ward (the number of air changes is 10-15 times/hour), and it is recommended to minimize the actions that will produce aerosols (such as open suctioning, bronchoscopy, flushing toilets without lids, etc.) or to increase the powerful exhaust air. A soiled room should be provided to organize all medical waste. If there are conditions, the dirt room can be set up external access to reduce the impact of the medical waste transportation process on the medical environment; without conditions, in accordance with the new crown medical waste collection requirements out of the ward plus a set of yellow garbage bags, gooseneck closed, special barrel storage, regular collection of specialized personnel, transported from the patient's entrance and exit.
The protective effect of goggles is worse than that of a protective face screen. The purpose of wearing goggles is said to be to prevent aerosol infection through the conjunctiva of the eye. Protective face screens are significantly larger than goggles and provide significantly more protection. More importantly, the face shield is on the outside of the N95 mask and can effectively block droplets from patients who cough, sneeze, or perform medical procedures.
