Anti-choking device

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.

2. The device of claim 1 further comprising a nozzle disposed within the through passage, the nozzle including a constricted portion defining a bore having a cross section of lesser area than the cross section of the through passage near the inlet port.

3. The device of claim 1 , wherein a first longitudinal axis extending between the inlet port and the connection region of the through passage is substantially aligned with a second longitudinal axis extending between the release port of the source of pressurized air and a base portion of the source of pressurized air opposite the release port.

4. The device of claim 1 further comprising a mask connected to and in communication with the vacuum passage.

5. The device of claim 1 further comprising a mouth tube connected to and in communication with the vacuum passage.

6. The device of claim 1 further comprising a piercing pin disposed within the through passage for piercing a seal covering the release port of the source of pressurized air.

7. A device for dislodging an object obstructing a person's airway comprising:

a through passage having an inlet port at one end and an exhaust port at an opposite end;

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;

a mouth tube connected to and in communication with the vacuum outlet port for engaging a person's airway; and

a compressed fluid container having at one end a release port mounted to the inlet port of the through passage and a base portion at an opposite end, wherein a primary axis extending between the release port and the base portion of the compressed fluid container is substantially aligned with a secondary axis extending between the inlet port and the connection region of the through passage; and

wherein 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.

8. The device of claim 7 further comprising a nozzle disposed within the through passage, the nozzle including a constricted portion defining a bore having a cross section of lesser area than the cross section of the through passage near the inlet port.

9. The device of claim 7 further comprising a mouth tube connected to and in communication with the vacuum passage.

10. The device of claim 7 further comprising a piercing pin disposed within the through passage for piercing a seal covering the release port of the source of pressurized air.

11. 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, the inlet port defining a first bore having a first cross section;

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 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;

a nozzle disposed within the through passage, the nozzle including a constricted portion defining a second bore having a second cross section of lesser area than the first cross section; 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 through the through passage creates a suction force at the outlet port of the vacuum passage capable of dislodging the object obstructing the person's airway.

12. The device of claim 11 , wherein airflow from the source of pressurized air creates a first directional airflow through the through passage and a second directional airflow through the vacuum passage in a direction substantially normal to the first directional airflow.

13. The device of claim 11 , wherein a first longitudinal axis extending between the inlet port and the exhaust port of the through passage is substantially aligned with a second longitudinal axis extending between the release port of the source of pressurized air and a base portion of the source of pressurized air opposite the release port.

14. The device of claim 11 , wherein the longitudinal axis of the nozzle is substantially aligned with the longitudinal axis of the through passage.

15. The device of claim 11 , wherein the constricted portion of the nozzle is characterized by a frustoconical shape.

16. The device of claim 11 further comprising a mouth tube connected to and in communication with the vacuum passage.

17. The device of claim 1 wherein the inlet port includes a passage opening that is oriented at a right angle to a passage opening of the exhaust port.

18. The device of claim 1 wherein the curved passage is downstream the release port and the vacuum passage.

19. The device of claim 1 wherein the through portion is a straight through portion.
