An emergency handling device for accidental faults of an artificial ventilator is installed in an air supply pipeline of a respirator and comprises an outer shell, an air inlet end, an air outlet end and an emergency air chamber, wherein the air inlet end is formed on one side of the outer shell, the air outlet end is formed on the other side of the outer shell, the air inlet end and the air outlet end are communicated through a closed air conveying pipe in the outer shell, the emergency air chamber is further arranged above the air conveying pipe in the outer shell, and the emergency air chamber is communicated with the air conveying pipe through a breathing hole formed in one side of the air inlet end; the air inlet end is also in threaded connection with an air inlet end cover, and a silica gel fish mouth one-way valve capable of controlling the flow direction of an air path in the air delivery pipe is arranged in the air inlet end cover; the two sides of the emergency air chamber are respectively communicated with an emergency self-suction port and an emergency self-exhalation port.
The silica gel fish mouth one-way valve can seal the connection of the air delivery pipe and the breathing hole when being opened, so that the air inlet end, the air outlet end and the air delivery pipe form a closed air path.
When the one-way valve of silica gel fish mouth is closed, can seal being connected of gas-supply pipe and inlet end and make end, gas-supply pipe and emergent air chamber of giving vent to anger form airtight gas circuit.
A medical oxygen connector is arranged outside the self-suction port; the self-suction port is positioned in the emergency air chamber and is also provided with a one-way valve A which only allows air to enter the emergency air chamber.
The self-exhalation port is positioned outside the emergency air chamber and is also provided with a one-way valve B which only allows air to be exhausted.
The utility model discloses a theory of operation does:
the device is arranged in the breathing machine air supply pipeline under the normal condition, and when the breathing machine works normally, the device only plays a role in air conveying, and air passes through the one-way valve of the silica gel fish mouth from the air inlet end in a one-way mode and is delivered to a patient end from the air outlet end. Wherein the one-way valve of silica gel fish mouth seals the respiratory orifice, plays the isolated effect with external. When the respirator has an accident fault, the respirator stops air supply at the moment, and the breathing hole which is originally in a closed state is communicated with the outside. When a patient with spontaneous breathing action inhales, the generated negative pressure opens the one-way valve A, and outside air flow enters the emergency air chamber in the device through the breathing hole, enters the air outlet end and is delivered to the patient end to realize inspiration. When the patient exhales, the airflow reversely passes through the air outlet end and the breathing hole along the pressure gradient to enter the emergency air chamber, the one-way valve B is opened while the one-way valve A is closed, and the air is exhausted to the outside to realize the exhalation.
