Anti-choking device

摘要

An apparatus for use in dislodging a particle from a choking person's airway. The apparatus including a venturi vacuum pump, a source of compressed fluid and a mask. The apparatus operating such that after the mask is placed over the choking person's nose and mouth, compressed fluid flowing through the venturi vacuum pump generates a low pressure region in the mask and correspondingly the person's airway which dislodges the particle.

主权项

1. A device for dislodging an object obstructing a person's airway comprising:
a through passage having a through portion including an inlet port at one end and an exhaust port at an opposite end; a curved passage forming a portion of the exhaust port and extending away from the through portion; a vacuum passage connected to the through passage at a connection region between the inlet port and the exhaust port of the through passage, the vacuum passage including a vacuum outlet port and a vacuum inlet port communicating with the through passage; and a source of pressurized air having a release port mounted to the inlet port of the through passage, whereby airflow from the source of pressurized air creates a first directional airflow through the through passage at the connection region and a second directional airflow through the vacuum passage in a direction substantially normal to the first directional airflow such that the second directional airflow creates a vacuum capable of dislodging the object obstructing the person's airway.
