Abstract
A flow controller includes a housing having central portion and finger-gripping portions on either side of said central portion. The housing defines an interior flow path and includes a breakable member at least partially positioned within the interior flow path of the housing to prevent the passage of fluid through the flow path. The breakable member includes a stem integrally molded to a tubular member. The finger-gripping portions have a cross sectional area greater than the cross sectional area of the central portion. The central portion includes a wall having a selected thickness.
Claims6
A fluid flow controller comprising:
- a housing including central portion and finger-gripping portions on either side of said central portion,
- said housing defining an interior flow path and including a breakable member at least partially positioned within said flow path of the housing to prevent the passage of fluid through the flow path;
- said breakable member comprising a stem integrally molded to a tubular member;
- said finger-gripping portions having a cross sectional area greater than the cross sectional area of said central portion;
- and
- said central portion comprising a wall having a selected thickness.
A fluid flow control system comprising:
- a first fluid source;
- a first fluid flow path in fluid communication with the first fluid source;
- a flow controller with a housing including a central portion and finger-gripping portions on either side of said central portion;
- said housing defining an interior flow path for receiving fluid from the first fluid flow path and including a breakable member comprising a stem integrally molded to a tubular member at least partially positioned within an interior flow path of the housing to prevent the passage of fluid through the flow path;
- a second fluid flow path in communication with said housing when the stem of the breakable member is separated from the tubular member;
- a container in fluid communication with said second fluid flow path.
