Abstract:
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.

CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    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 FIELD 
       [0002]    The 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 INVENTION 
       [0003]    The 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. 
         [0004]    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 &#39;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. 
         [0005]    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. 
         [0006]    The foregoing patents are incorporated herein by reference as fully as if they had been set forth in their entireties herein. 
         [0007]    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 &#39;238 patent requires visual location and identification of insects and further requires the collected insects, which may still be alive, to be properly killed. 
         [0008]    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. 
         [0009]    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 INVENTION 
       [0010]    The 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. 
         [0011]    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. 
         [0012]    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. 
         [0013]    In one form of the portable apparatus, the temperature change is generated by at least one thermal grid in communication with the airstream. 
         [0014]    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. 
         [0015]    In another form of the portable apparatus, the temperature change is adjustable by a user of the portable apparatus. 
         [0016]    In one form of the portable apparatus, the ultraviolet radiation increase is adjustable by a user of the portable apparatus. 
         [0017]    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. 
         [0018]    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. 
         [0019]    In yet another form of the portable apparatus, the collection chamber further comprises a removable bag. 
         [0020]    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. 
         [0021]    In another form of the portable apparatus, the removable bag is disposable. 
         [0022]    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. 
         [0023]    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. 
         [0024]    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. 
         [0025]    In yet another form of the portable apparatus, the fan assembly is adjustable to adjust the flow rate of the airstream. 
         [0026]    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.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0043]    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. 
         [0044]    Referring now to  FIG. 1 , the numeral  10  identifies generally a portable apparatus or cleaner for the collection of bedbugs and larvae and eggs. Cleaner  10  has a body  12  with a collection port  20  at one end. A nozzle  14  may be removably attached to the collection port  20 . Nozzle  14  has a nozzle port  16  at one end thereof communicating with a neck  18  which, in turn, is inserted into collection port  20  of body  12 . A handle  22  is attached to the exterior of cleaner body  12 . The cleaner  10  may be provided without the any nozzle  14 . In some applications the body  12  may be built into a stationary structure and the body  12  need not be provided with a handle  22 , and further need not be portable. 
         [0045]    Shown schematically in  FIG. 1  are collection grids  24 ,  26  and  28 , a collection bag  30  and a source of ultraviolet light  32 . 
         [0046]    Referring now to  FIG. 2 , an exploded view of cleaner  10  is shown. In particular, body  12  is shown as having been removed to reveal the placement of vacuum motor or fan assembly  34  and thermal grids  26  and  28 . In the embodiment shown, grids  24 ,  26  and  28  and motor  34  are preferably permanently mounted in front housing  36 . A power cord  38  is used to provide electrical energy to grids  24 ,  26  and  28  and motor  34 . 
         [0047]    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. 
         [0048]    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. 
         [0049]    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. 
         [0050]    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. 
         [0051]    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. 
         [0052]    Referring now to  FIG. 3 , the numeral  40  identifies a vacuum nozzle having a connection neck  42  and a body  44  within which a rotating brush  46  is located. Use of brush  46  provides agitation of the surfaces being vacuumed which, it is anticipated will dislodge bedbug organisms, molting of bedbugs, and bedbug feces. 
         [0053]    Referring now to  FIG. 4 , the numeral  48  identifies a nozzle having a collection stem  50 , a body  52  and a flexible, pliable and distortable lip  54 , useful for wedging nozzle  48  into unusually configured spaces. 
         [0054]    It is known that bedbugs lay their eggs in such hiding places in bedding as sewn seams, and that adult bedbugs as well as their larvae will conceal themselves in small cracks and crevices. To make collection of bedbug organisms more efficient, collection nozzles such as those shown in  FIGS. 5-7  may be used. 
         [0055]    In  FIG. 5 , the numeral  56  identifies a nozzle having a body  58  sized to fit into port  20  of the cleaning apparatus (not shown) and a tapered tip  60  formed as a “crevice tool” to allow tip  60  to be inserted into smaller and more hidden spaces. 
         [0056]    Referring to  FIG. 6 , the numeral  62  identifies a nozzle having a connecting neck  64 , a hollow body  66  and a nozzle end  68  formed in a flattened configuration tapering from a larger dimension at mouth  70  to a smaller dimension where nozzle  68  meets body  66  at  72 . Such a configuration provides for a nozzle which will fit into confined spaces and which, due to the tapered configuration of nozzle  68  will accelerate the flow of air into body  66  and, thereby, into cleaner  10 . 
         [0057]    Referring now to  FIG. 7 , the numeral  74  identifies a nozzle having a body  76 , at one end of which a flattened, broadened and angled collection port  78  is formed and at the other end of which a port  80  is formed sized to be accommodated by port  20  in cleaner  10 . 
         [0058]    Referring to  FIG. 8 , a modified collection bag is identified by the numeral  82 . Bag  82  has a bag inlet  84  and defines a collection chamber  86  within bag  82 . 
         [0059]    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. 
         [0060]    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 . 
         [0061]    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. 
         [0062]    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 . 
         [0063]    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. 
         [0064]    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  FIG. 2  where a hose  90  is shown connected to housing  36 . Hose  90  has a port  92  to which nozzles such as those shown in  FIGS. 3-7  are attachable. 
         [0065]    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. 
         [0066]    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. 
         [0067]    Referring now to  FIG. 9 , the numeral  94  indicates generally a circular fixed grid suitable for use as plate  24  to  26  or  28 . Grid  94  has an outer grid rim  96  and a plurality of horizontal rods  98  intersecting with a plurality of vertical rods  100  to form a pattern of substantially rectilinear spaces through which the air flow from apparatus  10  is directed. Grid  94  is preferably formed from a material that conducts heat efficiently to achieve sufficiently high temperatures to kill the organisms drawn in to contact therewith. 
         [0068]    Referring now to  FIG. 10 , the numeral  102  identifies generally another embodiment of a fixed grid having an outer rim  104  within which are fastened a plurality of horizontally curved rods  106  intersecting with a plurality of vertically curved rods  108 . A space is defined by ribs  106  and  108  vary in size and shape and provide a varied contact area for organisms drawn through grid  102 . As with grid  94 , grid  102  can be used as one or more of plates  24 ,  26  or  28 . 
         [0069]    Referring now to  FIG. 11 , the numeral  110  identifies generally a fan-type plate having an outer supporting frame  112  in which a fan assembly having a plurality of blades  114  is supported. Blades  114  are rotatably mounted to a hub  116 . Assembly  110  may be powered by a motor, such as an electric motor (not shown) or blades  114  may be angled such that fan assembly  110  rotates in the air stream drawn through apparatus  10 . 
         [0070]    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 . 
         [0071]    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. 
         [0072]    Referring to  FIG. 12 , the numeral  118  identifies generally a killing chamber to be used to collect and kill organisms drawn through cleaner  10 . Chamber  118  is a generally conical wall  120  with an open end  122  and a closed end  124 . A fine mesh  126  can be used as an exhaust for air drawn into chamber  118 . Mesh  126  may also be formed of a conductive material such as stainless steel and heated to a temperature sufficient to kill any organisms that survive the trip to collector  118 . A mounting flange  128  is provided to attach chamber  118  within the body  12  of the cleaner  10 . It is a feature of the invention that chamber  118  can be easily removed, washed and returned to service. 
         [0073]    Referring now to  FIG. 13 , the numeral  130  identifies generally another embodiment of a collection wand having a tubular body  132  terminating at a first end  134  at a port attachable to port  92  of hose  90 . Wand  130  also has a collection port  136  at its distal end. 
         [0074]    A magnifier  138  is mounted to the distal end of wand  130  to assist a user in locating dead bugs and their eggs and larvae for collection. Wand  130  also includes a light  140  formed proximate collection port  136  to provide additional assistance in locating adult bed bugs, their eggs and larvae for collection and destruction. It is understood that positions of magnifier  138  and light  140  may be varied to provide for a desired view of the area to be treated. It is also understood that expedients such as magnifier  138  and light  140  may also be included in the various collection nozzles described hereinabove. 
         [0075]    Referring now to  FIG. 14 , a chart is provided that informs the user of the time in minutes to eliminate 100 percent of various insect populations at various temperatures. For example, at 115 degrees Fahrenheit it will take approximately 480 minutes to destroy 100 percent of bedbug eggs, 90 minutes to destroy 100 percent of the bed bug adult insect population, 58 minutes to destroy 100 percent of German cockroaches collected, 123 minutes to destroy 100 percent of any flour beetles collected, 265 minutes to destroy 100 percent of any dry wood termite nymphs collected, and 8 minutes to destroy 100 percent of any Argentine adult ants collected. 
         [0076]    The chart of  FIG. 14  demonstrates that, at a temperature of 130 degrees Fahrenheit, 100 percent of bedbug eggs and adults are destroyed in less than one minute while destruction of German cockroaches takes 7 minutes, adult flour beetles takes 4 minutes, dry wood termite nymphs takes 6 minutes and adult Argentine ants takes 1 minute. It can readily be seen that designing a collection apparatus with the capability of maintaining temperatures in the 125 to 130 degrees Fahrenheit range will provide superior killing times and qualities for bedbug eggs and adults and improved qualities for destroying other insects. According to Doggett et al., in “Bed bugs: clinical relevance and control options”, published in Clinical Microbiology Reviews 25(1): 164-92, which is fully incorporated herein, it has further been shown that bedbugs may be killed after being subjected to a temperature of less than about 1 degree Fahrenheit for a period of about two hours. 
         [0077]    It is a feature of the present invention to have a collection chamber capable of maintaining a steady temperature in a range sufficiently high or low enough to kill selected organisms within a relatively short time period. To that effect, kill chamber  118  can include an electrically energized heat sink, positioned proximate mesh  126  to provide an additional killing capability for collected insects. 
         [0078]    Referring to  FIG. 15 , a partial schematic view of a mechanical forcing mechanism  1000  is shown, which may be optionally included in the portable apparatus  10 . The mechanical forcing mechanism  1000  illustrated in  FIG. 15  is comprised of two rollers  1010  and  1020 , which may be in rolling or spaced apart a sufficient degree to mechanically degrade, crush, pulverize bedbugs, larvae, eggs, and/or their debris. One or both of the rollers  1010  and  1020  may be driven. A transfer belt  1030  may be provided for transferring the bedbugs, larvae, eggs, and their debris from a vacuum inlet port  1040  through a duct or funnel  1050 , through the rollers  1010  and  1020 , and into a collection chamber  1060  for further processing or degradation. The belt  1030  may further be charged to transport the bedbugs, larvae, eggs, and/or their debris electrostatically. The location of the mechanical forcing mechanism  1000  may be anywhere in the airstream of the apparatus  10 , but it is preferably located intermediate the inlet port  1040  of the vacuum and the collection chamber  1060 . Inclusion of the forcing mechanism  1000  can decrease the number of, or the energy required for, the other processing steps or killing means for ensuring destruction of the aspirated bedbugs, larvae, eggs, and their debris. In some embodiments of the apparatus  10 , the forcing mechanism  1000  may be used alone, as the sole means to destroy or otherwise kill aspirated bedbugs, larvae, eggs, and their debris. 
         [0079]    While the forcing mechanism  1000  is illustrated as a pair of rollers  1010  and  1020 , other mechanisms for crushing or otherwise mechanically degrading the bedbugs, larvae, eggs, and their debris may be used, such as contacting or near-contacting cams, plates, gears, or any combination thereof. 
         [0080]    The foregoing disclosure of specific embodiments is intended to be illustrative of the broad concepts comprehended by the invention.
