Pay attention to the temperature and humidity When the humidity in the booth is high, if the weather is good, let the small mouth ventilate for 15 to 20 minutes one hour after the shed is pulled, reduce the humidity in the booth, and gradually expand the ventilation. Do not ventilate when the temperature of the shelf reaches 30°C or more to prevent the occurrence of large temperature and humidity changes.

The design of the new humanized protective surgical gown has been improved in the key areas of the gown. The forearm and chest area are double-thickened, and there are handguards in front of the chest and abdomen.
