Canned Vacuum Devices for Collecting and Storing Materials and Methods of Use

摘要

A vacuum device that operates without aid of a pump. More specifically, a vacuum device that utilizes a negative pressure container capable of providing sufficient vacuum or aspiration force to collect solid, liquid, or gas material(s) and which does not require a pump to facilitate aspiration during the collection process. A valve apparatus and conduit can be operably connected to a single opening in the vacuum device. A float valve assembly within the conduit can inhibit the intake of air into the container.

主权项

1. A vacuum device comprising:
a container having a proximal end and a distal end, where the container maintains a negative pressure of up to one atmosphere, and further has,
an intake at or near to the proximal end, anda vent within the container having a first opening in an operable position at or near to the intake and a second opening further within the container;an evacuation channel within the container having a pump port adapted to be connected to a pump for evacuating air from the container and an evacuation port located within the container, a conduit operably connected to the intake that is used to aspirate material into the container.
