Apparatus For Controlling Bedbugs
A portable apparatus for the collection of bedbugs, their eggs, their larvae, their debris, and their feces has a vacuum-producing motor disposed within a housing. A collection port is used to draw the bedbugs into the housing along a flow path to a collection chamber featuring a variable environment sufficient to kill the bedbugs. The collection chamber can be heated or cooled, can contain insecticidal substances, or ultraviolet radiation sufficient for killing the collected bedbugs. The flow rate and temperature ranges are adjustable to create sufficient heat and time of contact to kill selected organisms. The apparatus is especially useful for treating bedbug infestations in their natural environment without the need for toxic chemicals, long-term treatments that make the space being treated uninhabitable and other more extreme treatment regimens.
This application claims priority from U.S. Provisional Patent Application 61/394,677, filed Oct. 19, 2010 and entitled “Apparatus and Method for Controlling Bedbugs”, and is a continuation-in-part application based on U.S. patent application Ser. No. 13/277,105, filed Oct. 19, 2011 and entitled “Apparatus and Method for Controlling Bedbugs”, all of which are hereby incorporated herein by reference in their entirety.
TECHNICAL FIELDThe invention relates to an apparatus for collection and eradication of organisms and more specifically to the collection and eradication of bedbugs, bedbug larvae, bedbug eggs, and debris and feces thereof.
BACKGROUND OF THE INVENTIONThe bedbug, a well-known pest, has enjoyed a recent resurgence. While theories and explanations for the cause of increased numbers of bedbugs are many, the most frequently expressed are the discontinuance of lethal pesticides, a growing resistance to pesticides, and the presence of bedbugs and larvae in imported goods and packaging for goods. It has been reported that bedbugs cannot survive a temperature above 115 degrees Fahrenheit (46 degrees Centigrade), and various devices and methods have attempted to take advantage of this fact.
One example, U.S. Pat. No. 7,690,148 (Hedman) teaches and describes a method of treating pests which comprises heating an enclosed space to a temperature above that necessary to kill insects such as bedbugs, bedbug larvae, and eggs. The '148 patent and related U.S. Pat. Nos. 6,892,491 and 6,327,812 all describe variations of this approach to controlling insect infestations.
U.S. Pat. No. 5,806,238 teaches and describes a biological vacuum device to enhance environmental quality in which a vacuum cleaner has a vacuum wand and a heated air exhaust tube. Heated air from the exhaust tube is used to flush bedbugs from their hiding places while the vacuum wand is used to collect them.
The foregoing patents are incorporated herein by reference as fully as if they had been set forth in their entireties herein.
Heating an entire enclosed space such as a residence is time consuming, costly, requires a great deal of equipment, is not adapted to be performed often and may damage some of the contents of the space. The use of the device described in the '238 patent requires visual location and identification of insects and further requires the collected insects, which may still be alive, to be properly killed.
Since the late 1990s, bed bugs of the species Cimex lectularius and Cimex hemipterus have undergone a worldwide resurgence. Such bed bugs are blood-sucking insects that readily bite humans. Skin reactions may occur as small macular lesions that can develop into distinctive wheals of about 2 inches in diameter, which may be accompanied by intense itching. Bullous eruptions may occur. Where bed bugs are numerous, the patient may have widespread urticaria or erythematous rashes. Bites tend to occur in lines along the limbs.
There are more than 40 pathogens that have been detected within bed bugs, but there is no definitive evidence that bed bugs transmit any disease-causing organisms to humans. Anemia may result when bed bugs are numerous, and their allergens can trigger asthmatic reactions. The misuse of chemicals and other technologies for controlling bed bugs may have a deleterious impact on human health, including significant psychological trauma. The control of bed bugs is challenging and should encompass a multidisciplinary approach utilizing nonchemical means of control and the judicious use of insecticides.
SUMMARY OF THE INVENTIONThe inventor of the present invention has determined that the collection and eradication of bedbugs may be accomplished through the use of a combination vacuum and heating device which is of a convenient size, may be used frequently and will not only collect but kill adult bedbugs and their larvae and eggs within the device and its collection system.
The inventor of the present invention has discovered how to provide a portable apparatus for the collection and destruction of at least one of bedbugs, bedbug larvae, and bedbug eggs. The apparatus has a body with a collection port at one end of the body, a collection chamber at another end of the body for retaining the at least one of bedbugs, bedbug larvae, and bedbug eggs, and a handle for gripping the body. The apparatus further has a fan assembly in communication with the collection port for drawing a vacuum to create an airstream through the collection port to the collection chamber for aspiration of the at least one of bedbugs, bedbug larvae, and bedbug eggs. The collection chamber has a variable environment sufficient to kill said at least one of bedbugs, bedbug larvae, and bedbug eggs.
One form of the portable apparatus has a variable environment that is at least one of: (1) a temperature change sufficient to kill the at least one of bedbugs, bedbug larvae, and bedbug eggs; and (2) an ultraviolet radiation increase sufficient to kill the at least one of bedbugs, bedbug larvae, and bedbug eggs.
In one form of the portable apparatus, the temperature change is generated by at least one thermal grid in communication with the airstream.
In one form of the portable apparatus, the temperature change is generated by a thermal mass heated to a temperature sufficient to kill the at least one of bedbugs, bedbug larvae, and bedbug eggs.
In another form of the portable apparatus, the temperature change is adjustable by a user of the portable apparatus.
In one form of the portable apparatus, the ultraviolet radiation increase is adjustable by a user of the portable apparatus.
In one form of the portable apparatus, the temperature of the collection chamber is increased to at least 115 degrees Fahrenheit for a period of time sufficient to kill the at least one of bedbugs, bedbug larvae, and bedbug eggs.
In another form of the portable apparatus, the temperature of the collection chamber is increased to between 115 and 130 degrees Fahrenheit for a period of time sufficient to kill the at least one of bedbugs, bedbug larvae, and bedbug eggs.
In yet another form of the portable apparatus, the collection chamber further comprises a removable bag.
In another form of the portable apparatus, at least a portion of the removable bag is formed from an electrically conductive material whereby electrical energy can be applied to the electrically conductive material to raise the temperature of the electrically conductive material to a degree sufficient to kill the at least one of bedbugs, bedbug larvae, and bedbug eggs.
In another form of the portable apparatus, the removable bag is disposable.
In one form of the portable apparatus, the apparatus further comprises a flexible, elongate member having a distal end and a proximal end attached to the collection port, and a nozzle attached to the flexible, elongate member distal end for aspirating bedbugs from restricted spaces.
In another form of the portable apparatus, the nozzle includes a light for locating the at least one of bedbugs, bedbug larvae, and bedbug eggs.
In yet another form of the portable apparatus, the nozzle includes a magnifying glass for locating the at least one of bedbugs, bedbug larvae, and bedbug eggs.
In yet another form of the portable apparatus, the fan assembly is adjustable to adjust the flow rate of the airstream.
In yet another form of the portable apparatus, the apparatus has a mechanical forcing mechanism in communication with the airstream at a location intermediate the collection port and the collection chamber. The mechanical forcing mechanism is for mechanically degrading the at least one of bedbugs, bedbug larvae, and bedbug eggs prior to the at least one of bedbugs, bedbug larvae, and bedbug eggs reaching the collection chamber. The mechanical forcing mechanism may be used in addition to, or separate from, a variable environment.
These and further aspects of the present invention may best be appreciated upon consideration of the accompanying drawings in which:
While the following describes a preferred embodiment or embodiments of the present invention, it is to be understood that this description is made by way of example only and is not intended to limit the scope of the present invention. It is expected that alterations and further modifications, as well as other and further applications of the principles of the present invention will occur to others skilled in the art to which the invention relates and, while differing from the foregoing, remain within the spirit and scope of the invention as herein described and claimed.

It is a feature of the present invention that the grids 24, 26 and 28, or any selected number of similar grids are electrically energized and heated to a temperature above that temperature at which bedbugs, their larvae and eggs are destroyed thus creating a first variable environment to kill the bedbugs, their larvae, and eggs. It is also a feature that one or more of grids 24, 26 and 28 is charged with a sufficient electrical voltage to destroy bedbugs, their larvae and eggs.
As has presently been reported in the prior art, exposure to 115 degrees Fahrenheit for seven minutes will kill all forms of bedbugs, larvae and eggs. For purposes of convenience throughout the term “bedbug organisms” shall be understood to include bedbugs, their larvae and eggs, as well as any other insects or pests to be collected.
It is anticipated that heating grids 24, 26 and 28 to a temperature higher than 115 degrees Fahrenheit may cause the destruction of the bedbug organism in a shorter time span.
When motor 34 is energized, a vacuum is drawn through nozzle 14 allowing the bedbug organisms to be collected and thereafter directed to housing 36 and grids 24, 26 and 28. After passing through grids 24, 26 and 28, the bedbug organisms are directed to a collection bag 30 in body 12. When collection is complete, bag 30 is emptied in a manner which will prevent the re-entry of any collected bedbug organisms into the space just cleaned. The body 12, including any collection bag 30 therein, may be collectively referred to as a collection chamber.
In the embodiment shown, an ultraviolet light 32 is positioned within collection chamber thus creating a second variable environment to kill the bedbugs, their larvae, and eggs. It is believed that the presence of ultraviolet light 32 may have an efficacious effect on the destruction of any bedbug organisms that may survive passage through grids 24, 26 and 28. A third variable environment may be created by lowering the temperature of the collection chamber such as through a heat exchanger and working fluid. The working fluid transports heat to the outside of the body 12. When the variable environment is in the form of a lowered temperature, the temperature will approach freezing conditions for a sufficient time period to kill bedbugs, bedbug eggs, and bedbug larvae.

At the bottom of collection chamber 86 is a thermal mass 88 capable of absorbing and holding heat for a period of time. Thermal material such as sand, or other heat capturing material are suitable for this purpose.
Operation of cleaner 10 may now be described. A vacuum device is used to collect bedbug organisms and direct the past and into components in the device that are heated to a sufficient degree to kill the organisms. In one embodiment, thermal grids 24, 26 and 28 are positioned within housing 36 and are heated electrically to a temperature sufficient to kill bedbug organisms. When motor 34 is energized air is drawn through a selected nozzle such as 14 and, thereby, through housing 36, collected bedbug organisms will be brought into contact with one or more grids 24, 26 and 28 and destroyed by the heat produced by said grids. Thereafter, the destroyed bedbug organisms are collected and held within bag 30 inside body 12. When vacuuming is complete, body 12 is removed and bag 30 is emptied. UV light 32 provides a source of control for those adults, larvae or eggs that may survive the trip into bag 30.
In another embodiment, bag 82 is used to collect vacuumed bedbug organisms after thermal mass 88 has been heated to a temperature sufficiently high to kill them. Controls are provided to not only energize and heat the thermal mass 88 but to keep it at a killing temperature for a sufficient time to effect full eradication of the insects collected even when power to the motor 34 may be interrupted.
In a third embodiment, cleaner 10 includes grids 24, 26 and 28, and bag 82 with thermal mass 88. In this manner, killing of bedbug organisms will occur early on at the grids, and thereafter, within bag 82.
Due to the heat produced by elements such as grids 24, 26 and 28, motor 34 will be manufactured from heat-resistant components, such as ceramic parts used in other heated fan-driven devices such as hair dryers and the like.
The invention has been depicted herein as a hand held, portable unit small enough and maneuverable enough to be picked up and run along mattresses, beneath beds, in corners and the like. It is also contemplated that the foregoing operations can be included in full sized room type vacuum device which may also include a wand extending from the vacuum cleaner and used to collect insect material from smaller or more restricted places. The schematic of such an arrangement is shown in
Airflow through cleaner 10 can be adjusted to provide more contact time with grids 24, 26 and 28 to make the destruction of bedbug organisms more efficient. In like fashion, circuit controls can be provided to adjust the temperature and the time of heating within thermal mass 88 to ensure more efficient and thorough destruction of bedbug organisms, collecting and destroying a variety of insects and microorganisms, and the description of the present invention with respect to control of bedbugs should not be read as a limitation of the scope of the present invention.
It is also a feature of the invention that in other embodiments the heated portions of the system (the plates and the collector bag) are turned off and the system is used as a conventional vacuum cleaner. REPA and other filters can also be used to screen air exhausted from the device to trap unwanted particles, including parts of bedbug organisms.

It is anticipated that fan assembly 110 will provide a mechanical killing force to organisms drawn through when organisms drawn through blades 114 contact said organisms. It may also be a feature of fan assembly 110 to heat blades 114 to temperatures sufficient to add an additional killing element. As described above, an assembly 110 may be used as one or more plates 24, 26, or 28.
It is also a feature of the present invention that fan assemblies such as 110 may be mounted to grids such as fixed grids 94 and 102, preferably in the center of each. In addition to the mechanical killing capability of fan assemblies such as 110 it is also expected that the air flow provided by such fan assemblies will also assist in clearing the grids of organisms that may become attached thereto. For example, fan assembly such as 110 positioned between a pair of fixed grids such as 94 or 102 can produce a vacuum sufficient to a draft to pull organisms off the front of the upstream grid without blowing them from the rear of the downstream grid.
