Benefits of technology

"The present invention provides a suction device that overcomes the disadvantages of prior art suction devices. The suction device includes a container with a propellant, a venturi device, and a heater. The device creates a vacuum in the interior of the container to suck in debris through a conduit. The container has a release valve and a pressure relief valve for controlling the release of the propellant and pressure in the interior of the container. The heater heats the propellant in the interior of the container. The technical effects of this invention include improved suction efficiency, simplified operation, and improved safety."

Problems solved by technology

Although such devices are useful, they rely on aerosol propellant in the can to generate the suction.

Embodiment Construction

[0023] Although this invention has been found to be particularly useful for suction devices and suction devices used for cleaning wounds and other similar medical reasons, those skilled in the art will appreciate that the applicability of the invention is not limited thereto. Those skilled in the art will appreciate that the present invention can be used for any container having at least a propellant disposed therein which is expelled from the container through a release valve. Furthermore, although it is also preferred that the suction device of the present invention be disposable, it can also be provided in a reusable configuration.

[0024] Referring now to FIG. 1a, there is illustrated a first implementation of the suction device of the present invention, the suction device being generally referred to by reference numeral 100. The suction device 100 consists of an aerosol container 102 having walls 104 defining an interior cavity 106. A propellant 108 is disposed in the interior c...

Abstract

A container including: at least one wall defining an interior cavity; a propellant disposed in the interior cavity; a release valve disposed in the at least one wall for selectively releasing the propellant from the interior cavity; and a heater for heating the propellant in the interior cavity. Preferably, the container is provided with a venturi device and operates as a suction device upon release of the propellant from the interior cavity into the venturi device.

Description

BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a portable suction device and more particularly, to a fully contained, disposable portable suction device for attaching to a can of compressed gas for creating a suction. [0003] 2. Prior Art [0004] Compressed gas cans for creating suction are well known in the art, particularly those having a venturi based nozzle head in which gas is discharged, such as that disclosed in U.S. Pat. No. 6,094,778 to Boukas, the contents of which is incorporated herein by its reference. [0005] The suction from such devices can be used for cleaning wounds and other similar medical reasons, particularly for field applications by medical emergency personnel. Although such devices are useful, they rely on aerosol propellant in the can to generate the suction. The suction is based on the evaporation of liquids to generate gas flow from the can. As a result, the temperature of the liquid drops rapidly (the li...
