GAS INJECTOR AND METHOD FOR DELIVERING GAS FOR PEST EXTERMINATION

摘要

Devices and method for the extermination of pests are described. These devices and methods may be used to inject gases, which may be inert gases, underground to inject the gas into burrows of pests. In one embodiment, the device is an earth penetrator with hole for injecting gas through discharge holes at the distal end. The discharge holes maybe covered during penetration to prevent dirt from entering into the device. A device for covering and uncovering the hole are provided. The device includes a valve to controllably deliver the gas to the discharge ports. The method includes covering the discharge ports, inserting the device into the ground, uncovering the discharge ports, and then injecting the gas.

1. An apparatus for providing gas from a gas source, where said apparatus includes a proximal end and a distal end adapted for delivering the gas, said apparatus comprising:
a first tube having a proximal portion near the proximal end and a distal portion near the distal end and including one or more holes through the wall of said first tube; a second tube coaxial with and disposed within said first tube, where said second tube has a proximal portion and a distal portion near the distal end and including one or more holes through the wall of said second tube; a port to accept gas from the gas source; and a passageway to provide fluid communication between said port and said one or more holes of said first tube; where said first tube and second tube are rotatably movable between:
a first configuration, wherein at least one hole of said first tube is aligned with at least one hole of said second tube, anda second configuration, wherein none of said one or more holes in said first tube align with any of said one or more holes of said second tube.
