CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of U.S. Provisional Patent Application Ser. No. 62/150443 filed Apr. 21, 2015, which is incorporated by reference herein in its entirety. 
     
    
     BACKGROUND OF THE INVENTION 
       [0002]    A majority of dental delivery systems in offices and remote field units rely on the use of self-contained water bottle systems which are prone to cross-contamination when used in accordance with commonly accepted cleaning procedures and present day protocols. 
         [0003]    Bacterial growth within the self-contained water bottle systems is well known and biofilm formation within the waterlines may lead to levels exceeding the 500 CFU/ml EPA standard for drinking water. Warm water in these systems coupled with low flow rates may greatly increase rates of bacterial colonization, which often occurs between existing maintenance procedures. Contaminated dental waterlines may pose a public health risk especially for the elderly and immunocompromised. 
         [0004]    Cross contamination with bacteria or viral pathogens may also occur during bottle replacement; most notable if the feeder tube is touched during the procedure. Touching of a feeder tube during a bottle replacement procedure may cause cross contamination with bacteria or viral pathogens. In addition, an insufficient frequency of water replacement within the bottle may result in elevated bacterial counts. The chance for error and cross contamination during bottle replacement may also increase with greater procedural frequency. 
         [0005]    In the past, most prior UV water purification units for use in a dental environment have relied upon the use of mercury arc bulbs. Mercury arc bulbs are bulky, relatively fragile, and operate at extremely hot temperatures during use. The use of mercury arc bulbs is potentially dangerous to dental practitioners and patients. 
         [0006]    In the past maintenance of dental waterlines has occurred through the use of chemical agents, operating on a continuous basis, during water delivery. The use of chemical agents during water delivery may impose a number of undesirable consequences. The use of chlorine as an agent may be caustic to metals and may not penetrate existing biofilm. Iodine may in rare instances give rise to allergic reactions to individuals. Hydrogen peroxide and acetic acid have been demonstrated to be an effective cleaning agent when used on an intermittent basis, followed by line flushing, however, intermittent maintenance of waterlines relying on the use of chemical agents frequently is unable to prevent the reintroduction of bacteria into the lines, resulting in the formation of a slime biofilm in a period of time as short as two weeks. 
         [0007]    Dental waterlines are subject to bacterial contamination and biofilm formation. Limiting the introduction of bacteria into the dental delivery systems including self-contained water bottle systems is problematic particularly when used in an office environment as well as remote dental field applications, where adequate water quality cannot be assured. 
         [0008]    A number of existing self-contained water bottle delivery systems use a seated bottom and narrow fill neck, which in turn increases the difficulty of maintaining and cleaning of a water bottle and/or the self-contained water bottle delivery system when replacing water within the bottle. 
         [0009]    Existing portable vacuum units used in non-traditional dental office environments such as a nursing home facility, or during remote dental field applications, may pose a risk for spreading pathogens as biohazard effluents. A system to improve and limit potential pathogen spread is problematic during dental procedures and oral evacuation in at risk settings, especially where aerosolizing and direct contact of bacterial or viral agents may occur. 
         [0010]    The art referred to and/or described above is not intended to constitute an admission that any patent, publication or other information referred to herein is “prior art” with respect to this invention. In addition, this section should not be construed to mean that a search has been made or that no other pertinent information as defined in 37 C.F.R. §1.56(a) exists.

         [0012]    Without limiting the scope of the invention, a brief description of some of the claimed embodiments of the invention is set forth below. Additional details of the summarized embodiments of the invention and/or additional embodiments of the invention may be found in the Detailed Description of the Invention below. 
         [0013]    A brief abstract of the technical disclosure in the specification is provided for the purposes of complying with 37 C.F.R. §1.72. 
       GENERAL DESCRIPTION OF THE INVENTION 
       [0014]    In some embodiments, a method and system device is disclosed to improve asepsis during dental delivery. The method and system device includes a self-contained water delivery apparatus having a UVC Light Emitting Diode (LED) light source which is constructed and arranged to replace existing self-contained water bottle delivery systems. During use, water is placed into the reservoir of the self-contained water delivery apparatus. The water in the reservoir interior is exposed to germicidal UVC irradiation which reduces bacterial and pathogenic contamination. The method and system device also includes a vacuum apparatus and vacuum efflux assembly having a UVC Light Emitting Diode (LED) light source, the vacuum efflux assembly being constructed and arranged to capture dental efflux, where exposure of the efflux in the vacuum efflux assembly to UVC irradiation improves the handling of biohazards generated during oral evacuation. 
         [0015]    In some alternative embodiments, the method and system device additionally includes a reservoir egress connector, an open ended reservoir body which may be formed of an FDA compliant medical grade UV resistant material, and a UVC LED light emitting unit. 
         [0016]    In at least one additional embodiment, the reservoir egress connector may be formed of an FDA compliant medical grade UV resistant material, having a plurality of ports, where certain ports provide an incoming air source air, and other ports provide purified water outflow, and additional ports support a pressure release function. 
         [0017]    In at least one alternative embodiment, the reservoir egress connector may include two flexible connectors that unite one or more UV grade tubes, which in turn extend into the reservoir body. 
         [0018]    In some embodiments, a self-contained water bottle delivery system is disclosed having a reservoir egress connector, the reservoir egress connector having at least one tube extending into the reservoir body to provide agitation of the water column to improve UV germicidal irradiation. 
         [0019]    In any number of embodiments, agitation of the water column may occur during hand piece, or a water syringe use, through the manipulation of a manual purge switch connected to a port, or by connecting a port to a power purge control box. 
         [0020]    In any number of embodiments, a port of the reservoir egress connector may be connected by an airline to the power purge control box, and the power purge control box may house an air activated electric switch, a normally closed air purge valve, a programmable timer module, and power input and power output adaptors. 
         [0021]    In at least one embodiment, air pressure upon turning on the unit activates the air electric switch and starts the programmable timer which powers and opens the purge valve for a desired number of seconds, which in some embodiments may be approximately 60 seconds. 
         [0022]    In some embodiments, the air purge valve remains open for an initial period of time of more, less, or equal to  60  seconds as power is supplied to the UVC LED light emitting unit facilitating agitation of the water within the reservoir body, whereupon UVC light emission is exposed to water column to completely irradiate the water column with UV light. 
         [0023]    In any number of embodiments, the UVC LED light emitting unit may be comprised of a light source body housing a UVC LED source emitting light having a wavelength in the range of approximately 270 nm to 280 nm, a heat sink and an internal ultracapacitor or rechargeable battery. The UVC LED light source unit may have symmetrical upper and lower assemblies, where the upper assembly has a UV grade window. The lower assembly may house an external DC power adaptor. 
         [0024]    In any number of embodiments, the symmetrical upper and lower assemblies permit connection of the UVC LED light emitting assembly to the reservoir body as well as connection to a base mount assembly. 
         [0025]    In any number of embodiments, a base mount assembly may be installed into portable dental delivery cases and portable dental delivery vacuum units. The UVC LED light emitting unit may be removed from the reservoir body or vacuum efflux reservoir, and attached to the case base mount assembly to provide germicidal UV light exposure into the case interior, reducing bacterial and pathogenic contamination within the case upon closure. 
         [0026]    In any number of embodiments, the UVC LED light emitting unit may be used in accordance with any method, device, or assembly described herein, including use within a case where the interior of the case has a reflective liner which may aid in distribution of germicidal light within the case upon closure. 
         [0027]    In at least one embodiment, the UVC LED light emitting unit may be used to provide germicidal UV light exposure into the case interior to reduce the potential for mold formation during case storage. 
         [0028]    In at least one embodiment, the UVC LED light emitting unit may provide germicidal irradiation to a vacuum efflux reservoir to purify biohazards generated during dental procedures. 
         [0029]    In some embodiments, the vacuum apparatus may include a vacuum efflux assembly having a UVC LED light emitting unit which is uniquely suited for use in a nursing home or outreach dental setting, with the incorporation of commercial non-spill input and output connectors that attach to the vacuum efflux reservoir by means of a unique sanitary adapter. 
         [0030]    In some alternative embodiments, the vacuum efflux assembly may be case mounted for portability, with the unique ability to operate closed, with the incorporation of commercial medical grade non-spill input and output connectors which pass through the exterior shell of the case. 
         [0031]    In some embodiments, the vacuum efflux assembly when mounted within a case may be preceded and connected to a removable and recyclable solids collector and followed by a medical grade air vacuum filter. 
         [0032]    In some alternative embodiments, a reflective liner on the interior shell of the case improves UVC LED irradiation of the case contents to minimize growth or spreading of bacteria and pathogens. 
         [0033]    In some embodiments, the vacuum adapter assembly provides agitation of the fluid efflux for complete UV germicidal irradiation through an increase in velocity and a decrease in pressure within the efflux intake manifold, which creates fluid movement within the reservoir through a connected UV grade tube. 
         [0034]    In some alternative embodiments, an increase in velocity and a decrease in pressure within the efflux intake manifold, allows introduction of an environmentally safe bactericidal and virucidal agent into the efflux intake manifold and vacuum efflux reservoir. 
         [0035]    In some embodiments, the vacuum adapter assembly includes an external luer lock fitting which connects to the efflux intake manifold to allow introduction of an environmentally safe bactericidal and virucidal agent into the vacuum efflux reservoir without opening the unit, maximizing asepsis and reducing the potential spread of pathogenic material. 
         [0036]    In some alternative embodiments, the method and system to improve asepsis during dental delivery may include a self-contained water delivery apparatus consisting of a reservoir made of an FDA compliant medical grade UV resistant polymer with a removable UVC LED light emitting unit. 
         [0037]    In some embodiments, the invention attaches to and replaces existing self-contained water reservoirs, which have a single delivery feed tube, and one air input orifice. 
         [0038]    In alternative embodiments, a reservoir egress connector provides an effective method for quick attachment, fluid agitation and unrestricted light transmission to provide germicidal irradiation. 
         [0039]    In at least one alternative embodiment, the reservoir connector has an additional air tube extension disposed proximate to the water delivery tube, providing a method for agitation of the water column for germicidal sanitation upon exposure to UV irradiation. 
         [0040]    In some embodiments, the air tube extension and water feed tube may be made of UV quartz or glass joined to the ports on the reservoir egress connector by short flexible extensions, facilitating reservoir attachment. 
         [0041]    In alternative embodiments, pressure release is provided during water agitation. Agitation of the water column may occur during hand piece use, water syringe use, a manual purge switch or by connection to a power purge control box. 
         [0042]    In some alternative embodiments, the invention is designed to be disassembled for complete cleaning with the use of biopharmaceutical sanitary gaskets and clamps. 
         [0043]    In some embodiments, a closed case vacuum system will improve asepsis and will incorporate commercial non-spill connectors that pass through the exterior shell of the case providing connection to an oral evacuation tip and for connection to a vacuum pump. Isolation, and containment of the components and germicidal UVC LED light irradiation will limit the chance for the spread of pathogens. 
         [0044]    In some embodiments, the invention may incorporate a vacuum efflux assembly, a removable and recyclable solids collection device, as well as a medical grade air vacuum filter. 
         [0045]    These and other embodiments which characterize the invention are pointed out with particularity in the claims annexed hereto and forming a part hereof. However, for further understanding of the invention, its advantages and objectives obtained by its use, reference should be made to the drawings which form a further part hereof and the accompanying descriptive matter, in which there is illustrated and described embodiments of the invention.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
       [0056]    The device and system to improve asepsis in dental apparatus is disclosed herein. In general, the device and system to improve asepsis in dental apparatus is indicated by the numeral  100 . 
         [0057]    In general, referring to  FIG. 1 , in at least one embodiment, the device and system to improve asepsis in dental apparatus  100  includes a self-contained water delivery apparatus  40  which includes a reservoir  11  made of an FDA compliant medical grade ultraviolet (UV) resistant polymer and a removable UVC light emitting diode (LED) light emitting unit  14 , emitting light having an approximate wavelength of between 270 nm to 280 nm. In some embodiments, the reservoir egress connection assembly  8  provides fixed mounting within or near the dental delivery unit (not shown). In some embodiments, reservoir  11  is partially transparent, translucent, or is transparent and is formed of a material other than FDA compliant medical grade ultraviolet (UV) resistant polymer. In some embodiments, reservoir  11  is formed of glass, plastic, or other material which permits passage of light having a wavelength of between 270 nm and 280 nm there through. In other embodiments where the reservoir  11  is cylindrically tubular in shape having an open lower end, reservoir  11  may be formed of any material which is resistant to ultra-violet irradiation or reservoir  11  may be opaque. Examples of materials resistant to ultra-violet irradiation include but are not necessarily limited to polymers, metals, composite materials and combinations thereof. 
         [0058]    In some embodiments, the reservoir  11  of the self-contained water delivery apparatus  40  may include a commercially available sanitary quick connection assembly  10  which is releasably secured to the reservoir  11  through the use of commercial sanitary clamps and gaskets  13 . Alternatively, the quick connection assembly numeral  10  may be rotatably secured or screwed into a sanitary adapter  12 . In some embodiments, the sanitary adapter  12  is releasably connected to the reservoir  11  through the use of gaskets and clamps  13 . 
         [0059]    In some embodiments, the self-contained water delivery apparatus  40  is joined to the reservoir egress connector assembly  8  through engagement to the quick connection assembly  10 , which in turn may be affixed to a commercial sanitary adapter  12 . 
         [0060]    In some embodiments, the top of the reservoir  11  is generally open where a water tight, air tight, and a pressure tight seal is created between the top of the reservoir  11  and the bottom of the sanitary adapter  12  and connection assembly  10 , by the tightening of the commercial sanitary gaskets and clamps  13 . In at least one embodiment, the upper commercial sanitary clamp and gasket  13  enables the disassembly of the quick connector assembly  10  from the reservoir  11  for cleaning. 
         [0061]    In some embodiments a lower commercial sanitary clamp and gasket  13   a  is used to secure the UVC LED light emitting unit  14  to a lower portion of the reservoir  11 . 
         [0062]    In at least one alternative embodiment, the self-contained water delivery apparatus  40  is not required to be connected to an outside water line. The independence of the self-contained water delivery apparatus  40  facilitates use in remote or field dentistry applications. 
         [0063]    In alternative embodiments, available water may be introduced into the reservoir  11  from an outside faucet, stream, or other water source following the detachment of the reservoir  11  from the upper commercial sanitary clamp and gasket  13  and quick connector  10  or water may be introduced through quick connector  10  upon releasing the reservoir egress connector assembly  8 . 
         [0064]    In some embodiments, air from a regulated, pressurized air source from a dental compressor, provides pressurization to the water within the reservoir  11 . The pressurized air enters into the reservoir egress connector assembly  8  through port  2  and exits the reservoir egress connector assembly  8  through port  2   a.  Pressurized air then passes through a flexible connector  7  into the upper portion of a UV grade tube  6 . This pressurized air course is identified by reference numeral  20 . In some embodiments, tube  6  is transparent and is formed of a material such as quartz. In some embodiments, tube  6  is formed of glass, plastic or other material which permits passage of light having a wavelength of between 270 nm and 280 nm there through. 
         [0065]    In some embodiments, the process of air introduction and/or air movement in the reservoir  11 , proximate to the bottom, or below the water column, provides agitation within the water column enhancing complete UV germicidal irradiation of the water column within the reservoir  11 . In some embodiments, the water agitation within the reservoir  11  may also occur when air pressure is released from a purge valve through ports  4  and  4   a.  The pressure release air course is identified by reference numeral  96 . 
         [0066]    In some embodiments, port  4  may be connected to a manual purge valve or alternatively, to a custom purge/power control box  21 , which in turn may provide time control functions to enable timed or preprogrammed agitation of the water column during UV irradiation from the UVC LED light emitting unit  14 . 
         [0067]    In at least one embodiment, the purge valve for the air supply may be oriented in a closed position. When pressurized air is introduced into the reservoir  11  through ports  2 ,  2 A, and tube  6 , (air course  20 ) pressure is exerted on the water column, which in turn will establish a fluid flow passage upwardly through a second UV grade tube  5 , enabling water which has been purified following exposure to UV light from the UVCLED light emitting unit  14 , to egress out of the reservoir  11  upon demand, which may occur when operating dental hand pieces or a water syringe during dental delivery. The fluid course from the reservoir  11  to port  3  is identified by reference numeral  98 . In some embodiments, tube  5  is transparent and is formed of a material such as quartz. In some embodiments, tube  5  is formed of glass, plastic or other material which permits passage of light having a wavelength of between 270 nm and 280 nm there through. 
         [0068]    The pressurization within the reservoir  11 , forces purified water up tube  5 , through a flexible connector  7   a,  and into port  3   a  and out of port  3  for distribution to dental hand pieces and/or a water syringe. (Fluid course  98 ) 
         [0069]    In some embodiments, as purified water is expelled from the pressurized reservoir  11  during the use of dental hand pieces or a water syringe, air pressure within the reservoir  11  is maintained through the introduction of additional air into the reservoir  11  by the use of a regulated air source, which may be in air communication with port  2 . 
         [0070]    In at least one embodiment, additional air will flow down tube  6  as a dental hand piece or water syringe is used during a dental procedure. (Air course  20 ) As water from the reservoir  11  is used during the dental procedure agitation of the water column may also occur as a result of the entry of additional air down the UV quartz tube  6 . The UVC LED light emitting unit  14  may continuously or periodically expose the water column in the reservoir  11  to UV germicidal irradiation. 
         [0071]    In some embodiments the bottom portion of the reservoir 11  is generally open, and the reservoir  11  is generally cylindrically tubular in shape. In other embodiments, the bottom of the reservoir  11  may be closed and may include an integral or an affixed pressure sealed UV grade quartz window or bottom. 
         [0072]    In some embodiments the UVC LED light emitting unit  14  may be releasably secured to the bottom portion of the reservoir  11  by the use of a lower sanitary clamp and gasket  13   a.  The lower sanitary clamp  13   a  enables the disassembly of the reservoir  11  from the UVC LED light emitting unit  14  for cleaning. In some embodiments, the UVC LED light emitting unit  14  includes a window  15  which is transparent, and which is formed of quartz or a material other than quartz. In some embodiments, window  15  is formed of glass, plastic or other material which permits passage of light having a wavelength of between 270 nm and 280 nm there through. In some embodiments, the bottom of the reservoir  11  does not include a window, however, the bottom of the reservoir  11  is open or closed, and in both embodiments the lower portion of the reservoir  11  permits light having a wavelength of between 270 nm and 280 nm to pass there through. 
         [0073]    In some embodiments the light emitting diode light sources are disposed below the window  15 , where the window  15  creates a water tight, air tight, and pressure tight seal preventing moisture or air exposure to the light emitting diode light sources of the UVC LED light emitting unit  14 . 
         [0074]    In some embodiments, a water tight, air tight, and pressure tight seal is established between the bottom portion of the reservoir  11  and the LED light emitting unit  14 , upon the tightening of the lower clamp and gasket  13   a.    
         [0075]    In some embodiments, water agitation within the water column in the reservoir  11  may also occur by the release of pressure within the reservoir  11  by the opening of the purge valve. The opening of the purge valve enables pressurized air to escape through port  4   a  and then port  4 . The release of pressure on the water column within the reservoir  11  causes the water within the reservoir  11  to agitate and mix facilitating germicidal purification and exposure to UV irradiation from the UVC LED light emitting unit  14 . 
         [0076]    In general, referring to  FIG. 2 , a reservoir egress connector assembly  8  is shown. In at least one embodiment the egress connector assembly  8  includes a head assembly  1 . The head assembly  1  is formed of an FDA compliant medical grade UV resistant polymer. The head assembly  1  includes six ports, namely, ports  2 ,  2   a,    3 ,  3   a,    4 , and  4   a.  In other embodiments, the reservoir egress connector assembly  8  may be constructed of metal, polymer, or other materials or combinations of materials provided that the features, functions, and/or attributes identified herein are not sacrificed. 
         [0077]    In at least one embodiment, pressurized air enters through port  2  traversing a passage to port  2   a.  The pressurized air then passes through the flexible connector  7  and enters into tube  6  for entry into reservoir  11 . 
         [0078]    In at least one embodiment, UV irradiated and purified water leaves reservoir  11  by the entry into the bottom of the UV grade tube  5  traversing upwardly through flexible connector  7   a  and into port  3   a.  The purified water then passes through a conduit from port  3   a  to port  3  for exit and use in a dental hand piece or water syringe or other dental device. 
         [0079]    In some embodiments, the use of flexible connectors  7  and  7   a  facilitates the ease of reservoir  11  attachment and release from the reservoir egress connector assembly  8  and/or the quick connection assembly  10 . 
         [0080]    In some embodiments, the use of the tubes  5  and  6  allows the complete irradiation of the interior reservoir contents without establishing shadowed or blocked areas which would occur if traditional tubing materials were utilized. In addition, the use of tubes  5  and  6  prevents the growth of pathogens within the interior of either of tubes  5  or  6 . 
         [0081]    In at least one embodiment as depicted in  FIG. 3  a purge/power control box  21  is shown. The purge/power control box  21  provides both an external and internal DC power source to the device and system to improve asepsis in the dental apparatus  100 . 
         [0082]    In at least one embodiment, port  22  provides an incoming pneumatic connection from port  4  of the head assembly  1 . Within the purge/power control box  21 , port  22  is connected to a pneumatic electrical switch which is normally open. The pneumatic electrical switch activation is triggered by an established air pressure differential. When air pressure into port  22  is increased to the established level, the pneumatic electrical switch closes. The closing of the pneumatic electrical switch also completes an electric circuit with an internal time delay relay module which in some embodiments may be programmable. The internal time delay relay may also provide power to the UVC LED light emitting unit  14 . The internal time delay relay may also provide electricity/power to a normally closed pneumatic air purge valve. 
         [0083]    In some embodiments, when the pneumatic air purge valve is opened, pressure is released from the reservoir  11  through port  4   a  and then through port  4 , for entry into port  22 , which is in airflow communication with the pneumatic air purge valve for exit through pneumatic connection  23  into the atmosphere. This airflow course permits continued airflow through ports  2 ,  2   a,  flexible tube  7 , as well as tube  6  when the pneumatic air purge valve is open. The continued air passage through tube  6  and ports  4   a,    4 , into port  22  provides agitation to the water column in reservoir  11 , allowing for complete UV irradiation of the water column. 
         [0084]    In some embodiments, the internal time delay relay module may be electrically connected to connector/source  24  which may be an external DC power lead, which may be used to provide a source of electricity for the UVC LED light emitting unit  14 . In some embodiments connector/source  24  may be a commercial DC power lead jack. 
         [0085]    In some embodiments when the pneumatic air purge valve is closed air will continue to enter into reservoir  11  through ports  2 ,  2   a,  flexible tube  7 , and tube  6  to increase pressure within the reservoir  11 . Once the air pressure within the reservoir  11  reaches an established threshold, the pneumatic electrical switch will be triggered, closing the circuit to the pneumatic purge valve to open the pneumatic purge valve to release pressure/air as previously described. When the air pressure drops to a preselected level the pneumatic electrical switch will open breaking the circuit to the pneumatic purge valve to close the pneumatic purge valve to allow pressure within the reservoir  11  to increase. In the closed operational position air is not permitted to pass through the pneumatic purge valve, which in turn increases air pressure within the conduits between ports  22 ,  4 ,  4   a  and within reservoir  11 .
