Automatic Airtight doors are usually installed in operation rooms and have strict hygiene requirements. The use of automatic doors as carriers can ensure convenient passage, achieve automatic opening of airtight automatic doors, and effectively prevent health hazards caused by human contact. The automatic door activation and opening system is an important part of medical door design. There are various ways to open medical airtight doors, and most of the methods used in the market include foot sensing sensor, hand press sensor and hand sensing sensor, let’s learn more about such ways.

Foot sensing sensor: Generally speaking, the foot sensing sensor is the most common opening device for airtight automatic doors in hospitals .When opening the door, you only need to put your foot into the foot sensing switch to open the door. The foot switch operates the circuit by stepping on or off, and can also be used to control the output current of the switch. This switch has been widely used in automatic airtight doors. The main reason is that it can replace both hands in the control circuit that cannot be touched by both hands to achieve the purpose of operation, which can enable medical personnel who enter and exit the hospital's automatic airtight door to enter and exit in a timely manner, improving efficiency. PT12 series through beam sensor is one compact design mini-shape photocell. A “Snap-In”mechanism and 45°outlet mode allows fast mounting in a mounting hole with 12.5-13.5 mm diameter; Mini shape, can be applied to the miniaturization of devices; ClassⅡsafety circuit design to be used for fault detection of sensor; Epoxide resin sealing is suitable for rugged environment.

Hand sensing sensor:  Such sensors can be divided into two types, one is opening by touching door, and the other is opening by sensing door. As the name suggests, touching a switch is necessary to open the hospital's airtight automatic door, while sensing only requires approaching the switch to open the hospital's airtight automatic door. The advantage of sensing compared to touch and button switches is that it can open the hospital's airtight automatic door more quickly without touching the switch, avoiding cross infection of bacteria

Infrared sensing: When personnel appear in the infrared sensing area and the hospital's airtight automatic door will automatically open. This method can also determine the walking route of personnel. If you only pass by and pass through the sensing area, you will not open the door. However, in some hospitals, such as operation rooms, this method is not chosen because infrared sensing can easily open the door by mistake.

Door handle: This is a door opening method that requires manual pushing and pulling to open the door, and is also equipped with airtight automatic doors in hospitals. It can be used as an emergency door opening method to prevent power outages.
