Airflow devices and related methods

Abstract

Airflow devices are described. An airflow device may include a first body and a second body. The first body defines a central cavity and a first opening in fluid communication with the central cavity forming a first fluid passageway. The second body defines a second opening and a third opening in fluid communication with the second opening to form a second fluid passageway extending through the second body. The second body configured to be received within the first body such that the second fluid passageway of the second body is substantially aligned with the first fluid passageway of the first body. Related methods of manufacturing airflow devices are also described.

         10 . The airflow device of  claim 9 , further comprising a second cap configured to removably connect to a second end of the first body. 
     
     
         11 . The airflow device of  claim 1 , wherein the first body comprises a flexible base portion. 
     
     
         12 . The airflow device of  claim 1 , wherein the second opening and the third opening of the second body are coaxially aligned. 
     
     
         13 . The airflow device of  claim 1 , wherein the second body is configured to be received within the central cavity of the first body such that the second opening of the second body is coaxially aligned with the first opening of the first body. 
     
     
         14 . An airflow device, comprising:
 a first body defining a central cavity and further defining a first opening in fluid communication with the central cavity to form a first fluid passageway extending through the first body; and   a second body defining a second opening and further defining a third opening in fluid communication with the second opening to form a second fluid passageway extending through the second body, the second body positioned within the first body such that the second fluid passageway of the second body is substantially aligned with the first fluid passageway of the first body.   
     
     
         15 . The airflow device of  claim 14 , wherein the first body comprises:
 a first end;   a second end opposite the first end;   an outer wall extending from the first end to the second end of the first body, the outer wall defining the central cavity within the first body;   the first opening in fluid communication with the central cavity; and   a hollow stem adjacent to the central cavity, the hollow stem defining a fourth opening in fluid communication with the central cavity and the first opening.   
     
     
         16 . The airflow device of  claim 15 , wherein the second body comprises:
 an additional stem extending away from the second body and at least partially defining the second fluid passageway, the additional stem positioned within the hollow stem of the first body.
