Referring now to the drawings, FIGS. 1-6 illustrate an embodiment of a decontamination device 100 . Referring first to FIGS. 1-4 , the decontamination device 100 may include a housing 102 forming a handle portion 104 , a body portion 108 and a nozzle portion 110 . Body portion 108 may include bottom portion 107 , top portion 109 , front portion 111 and rear portion 113 . The handle portion 104 may include a front handle arm 112 extending from a top portion 109 of the body portion 108 near the front portion 111 and a rear handle arm 114 extending from the top portion near the rear portion 113, and between the front handle arm and the A handle 105 extends between the distal ends of the rear handle arms. A handle gap 116 may be formed in the space between the top portion 109 of the body portion 108 , the front handle arm 112 , the rear handle arm 114 and the handle 105 . In the embodiment shown, the trigger 106 may be provided on the handle 105 proximate the front handle arm 112 for access by the user through the handle gap 116 by holding the decontamination device 100 by the handle. Trigger 106 may be pressed into handle 105 upon activation. However, it should be understood that in other embodiments, the triggers 106 may be set in different configurations.

In the embodiment shown in FIGS. 1-4 , the nozzle portion 110 may be provided on the front portion 111 of the body portion 108 proximate the top portion 109 . The nozzle portion 110 may include a removable pull safety device 118 configured to at least temporarily close the final nozzle 120 (visible in Figure 5). The pull safety device 118 and its engagement with the decontamination device 100 can be best understood by comparing Figures 1 and 5, which show an embodiment of the device with the pull safety device in place, and Figure 5 showing the pull Embodiments of a device with a safety device removed. The pull safety device 118 may include a pull tab 122 , a central cover 124 and a tail 126 . When positioned on the nozzle portion 110 , the central cap 124 may engage the nozzle face 125 and fit within the nozzle ring 127 to enclose the final nozzle 120 . In some embodiments, the central cap 124 may have at least a slight interference fit with the nozzle ring 127 such that the pull safety device remains in place until pulled by the user. In some embodiments, the tail portion 126 may fit within a tail portion slot 128 formed in the front handle arm 112 . A tip aperture 130 may also be formed in the front handle arm 112 at the end of the tail slot 128 spaced away from the nozzle portion 110 . In some embodiments, tail tip 132 may fit into tip aperture 130, as discussed in more detail below. In one embodiment of the decontamination device 100, the pull safety device 118 may be removed by the user by pulling the pull tab 122 away from the nozzle portion 110 prior to dispensing fluid from the device. FIG. 6 shows another view of the decontamination device 100 with the pull safety device 118 removed. In some embodiments, the pull security device 118 may include a tamper-resistant system for removal. For example, fingers or accessories attached to the pull safety device may help to removably secure the pull safety device 118 to the decontamination device 100 . When the pull safety device 118 is removed from the nozzle portion 110, the fingers may deform, making it difficult or impossible to put the pull safety device back on the nozzle portion. This system can prevent the pull safety device 118 from being put back on a device that has been used and thus cannot hold a sufficient supply of material in its tank. An exemplary embodiment of such a system is described below with reference to FIG. 17 . Other safety device embodiments are also contemplated herein as alternatives to the pull safety device shown. For example, some embodiments may include pins inserted into one or more locations on decontamination device 100 that may mechanically or otherwise prevent or limit movement of trigger 106, cam member 162, mixing manifold 146, or other components , the result may be to prevent mixing or dispensing of materials.

FIGS. 7 and 8 illustrate an embodiment of the decontamination device 100 having a spray selector switch 134 formed on the nozzle face 125 that can be in the first position 136 (shown in FIG. 7 ) and move between the second positions 138 (shown in FIG. 8 ). As shown in FIGS. 7 and 8 , the nozzle portion 110 may include a nozzle ring 127 at least partially surrounding the nozzle face 125 and a final nozzle 120 formed through the nozzle face. A spray selector switch 134 may be positioned between the ends of the nozzle ring 127 . In some embodiments, the nozzle face 125 is rotatable relative to the nozzle ring 127 such that when the spray selector switch 134 is moved from the first position 136 to the second position 138 the nozzle face is rotated. In such an embodiment, when the spray selector switch 134 is moved, the shape or flow of the spray as the fluid is dispensed through the final nozzle 120 can be changed. For example, in some embodiments, the first spray mode may be obtained by the spray selector switch 134 in the first position 136 as shown in FIG. 7 and the second spray mode may be obtained by the spray selector switch in the first position 136 as shown in FIG. 7 obtained in the second position 138. Examples of spray patterns that can be created by the first or second position of the spray selector switch include, but are not limited to: Directional Wet Cone, Directional Wet Vertical Spray, Directional Wet Horizontal Spray, Wide Jet, Straight Jet, or allow for custom spray coverage other configurations. Also, while the embodiment shown in Figures 7 and 8 shows two spray selector switch positions, it is contemplated herein that the spray selector switch may have any number of positions to indicate any number of sprays that the user may select model. It is also contemplated that, in some embodiments, the spray selector switch may not be fixed to the nozzle face, but may move along the nozzle face and move other components within the nozzle section and affect the spray shape.

9 and 10 illustrate an embodiment of the decontamination device 100 with a portion of the housing 102 removed to show the components contained within the housing. In the embodiment shown in these figures, the body portion 108 houses the first canister 140 , the second canister 142 and the third canister 144 within the housing 102 . Although the embodiment shown herein shows an embodiment of the decontamination device 100 with three tanks, other embodiments with different numbers of tanks, such as two or more than three, are also contemplated herein. Furthermore, it is contemplated that in various embodiments, the canister may be of various types, such as, for example, an aerosol, valve-on-bag, or other techniques known to those skilled in the art. Alternatively, other dispensing designs or mechanisms may be employed in other embodiments. For example, some embodiments may include a preloaded syringe, or insert a dry and/or erodible material into the mixing manifold 146 . In some embodiments, each of the tanks 140 , 142 , 144 may be connected to a mixing manifold 146 that may be housed in the top portion 109 of the body portion 108 . Typically, each tank 140 , 142 , 144 may contain material within it to mix within the mixing manifold 146 and dispense through the final nozzle 120 of the nozzle section 110 when the trigger 106 is actuated. The material retained on the interior of each tank may vary from embodiment to embodiment and depending on the desired application. Some non-exhaustive examples of materials that can be contained in the tank are quaternary ammonium compounds, benzyl-C12-C16 alkyl dimethyl chloride, liquid hydrogen peroxide, and diacetin. In some embodiments, one tank can hold water with a quaternary ammonium compound held at about 120 pounds per square inch (psi), the other tank can hold a 7.99% hydrogen peroxide solution that is not stable at about 120 psi, And another tank can hold food grade diacetin. However, those skilled in the art will understand that in different embodiments, different combinations of different materials may be retained within the tank.

Other components of trigger 106 are also shown in FIGS. 9 and 10 . Specifically, the trigger 106 may include a first trigger arm 148 that is generally received within the handle 105 and a second trigger arm 150 that is generally received within the rear handle arm 114 . The first trigger arm 148 and the second trigger arm 150 may meet at a pivot portion 152 that may include a pivot aperture 154 for receiving a pivot fastener 156 . The pivot fastener 156 may be any type of fastener suitable for securing the trigger to the housing 102 through the pivot aperture 154 and allowing the trigger 106 to pivot about the pivot fastener 156 about the pivot portion 152 change. In some embodiments, pivot fastener 156 may be integral with housing 102 of decontamination device 100 . The trigger 106 may also include a trigger input 158 disposed at the distal end 149 of the first trigger arm 148 and a trigger output 160 disposed on the distal end of the second trigger arm 150 . Trigger input 158 may extend from handle 105 into handle gap 116 for access by a user holding decontamination device 100 . When the user depresses the trigger input 158 , the trigger 106 can pivot about the pivot fastener 156 , translating the substantially vertical movement of the trigger into a generally horizontal or lateral movement of the trigger output 160 .

While the embodiment shown in Figures 9 and 10 includes a pivoting trigger, other contemplated embodiments may include a link or cable and pulley system acting as a cam, which itself may take a variety of configurations. Additionally, the effect of the trigger on the injection duration may vary in different embodiments or combinations of different embodiments. For example, in some embodiments, the decontamination device 100 may be configured to mix and dispense the material only when the trigger 106 is actively depressed, and stop dispensing when the user releases the trigger. In other embodiments, the decontamination device 100 may be configured to begin mixing and dispensing when the trigger 106 is actuated, and continue to mix and dispense until the tank is emptied, regardless of whether the trigger remains depressed. In other embodiments, the trigger 106 may include a spray lock that locks the trigger in the depressed position.

In some embodiments, the top portion 109 of the body portion 108 may additionally accommodate a cam member 162 that may engage the mixing manifold 146 . The cam member 162 may have a trigger end 164 and a spring end 166 opposite the trigger end. The cam member 162 can move along a first axis 210 , which in some embodiments can be substantially horizontal or transverse with respect to the mixing manifold 146 between the trigger output 160 and the nozzle portion 110 . In some embodiments, spring 168 may engage cam member 162 to bias the cam member away from nozzle portion 110 and toward trigger output 160 . In some embodiments, and as shown in FIG. 15 , the spring end 166 of the cam member 162 may concentrically surround the member rod 169 of the cam member. The spring 168 may bear against the biasing rod 159 , which may be anchored to the housing 102 . Thus, when the user depresses the trigger input 158, the trigger output 160 can move against the trigger end 164 of the cam member 162 substantially along the first axis 210, which is in some embodiments can be basically horizontal. If the trigger input 158 is depressed with sufficient force to overcome the biasing force of the spring 168 , the cam member 162 may move relative to the mixing manifold 146 in a direction toward the nozzle portion 110 . Additionally, in some embodiments, the trigger may be configured in a palm-squeeze configuration, wherein, for example, the user's palm may press the trigger to activate the mechanism that activates the canister. In another embodiment, the trigger may be a thumb-press configuration that utilizes an internal mechanism to activate the canister.

11-13 show enlarged views of embodiments of the handle portion 104 and top portion 109 of the body portion 108, with portions of the housing 102 removed for clarity. Referring first to FIG. 13, the cam member 162 and the mixing manifold 146 may be oriented relative to each other such that at least one cam surface may translate movement of the cam member along the first axis 210 into movement of the mixing manifold along the second axis 215, which The second axis may be substantially perpendicular to the first axis in some but not all embodiments. In some embodiments, the first axis 210 may be a substantially horizontal axis and the second axis 215 may be a substantially vertical axis. In such embodiments, substantially horizontal movement of the cam member may be translated into substantially vertical movement of the mixing manifold. Specifically, in some embodiments, the cam member 162 may have a first cam surface 170, a second cam surface 172, and a third cam surface 174, and the mixing manifold 146 may have a first follower 171, a second follower A member 173 and a third follower 175 are engaged with the first cam surface, the second cam surface and the third cam surface, respectively. When the trigger output 160 pushes the cam member 162 toward the nozzle portion 110, the first cam surface 170, the second cam surface 172, the third cam surface 174 may abut the first follower 171, the second follower 173, respectively and the third follower 175 slides. Since the mixing manifold 146 is substantially limited or restricted in horizontal movement, movement of the cam surfaces against the followers of the mixing manifold exerts a vertically downward force on the mixing manifold. As a result, the mixing manifold 146 can be moved vertically downward from the passive position toward the first tank 140 , the second tank 142 , and the third tank 144 to the dispensing position. The cam and follower relationship between the cam member 162 and the mixing manifold 146 is also shown in cross-section in FIG. 14 . Although the embodiment shown here shows three corresponding cam surfaces and followers, embodiments of cam components and mixing manifolds have more or fewer corresponding cam surfaces and followers. In some embodiments, the number of cam surfaces and corresponding followers may correspond to the number of tanks used in a particular device. For example, a device containing two tanks may include a cam member with two cams and a mixing manifold with two corresponding followers. Additionally, in some embodiments, the cam member may be integrated into the trigger itself.

In some embodiments, vertical downward movement of the mixing manifold 146 may open the first valve 176 , the second valve 178 , and the third valve 180 between the first tank 140 , the second tank 142 , and the third tank 144 , respectively. of each, thereby releasing the tank contents into the mixing manifold. First tank 140 , second tank 142 , third tank 144 , their respective first valve 176 , second valve 178 , third valve 180 and mixing manifold 146 are best shown in FIG. 14 . interaction. 14 shows a cross-sectional view of one embodiment of the decontamination device 100, focusing on the top portion 109, and the interaction of the valve, tank, and mixing manifold. The embodiment shown in FIG. 14 includes different types of valves for the first valve 176 , the second valve 178 and the third valve 180 . In this embodiment, each of the first valve 176, the second valve 178, and the third valve 180 may include a direct connection to the mixing manifold 146 with integrated nozzles in the manifold. However, it is contemplated that other types of connections may be used in other embodiments. For example, the connections between the first tank 140, the second tank 142, the third tank 144, and the mixing manifold 146 may include a male nozzle on the top of the tanks that may be pressed into a gland on the mixing manifold Either on the contact seal, or the male nozzle can be pressed into the receiving cone on the mixing manifold, or other connections known to those skilled in the art.

In the embodiment of Figure 14, the mixing manifold 146 may be substantially hollow to form a mixing chamber 182 within the mixing manifold. The mixing chamber 182 may extend substantially the entire length of the mixing manifold 146 from the nozzle portion 110 to a chamber cover 184 that seals the mixing chamber opposite the nozzle portion. Additionally, a chamber insert 186 may be disposed within the mixing chamber 182 to be substantially surrounded by the mixing manifold 146 . The size and shape of the chamber insert 186 can affect the volume and flow pattern within the mixing chamber 182 . For example, a larger chamber insert may result in a smaller mixing chamber volume, and a smaller chamber insert may result in a larger mixing chamber volume. The size and shape of the mixing chamber 182 can affect the flow pattern and mixing quality of the various materials of the first tank 140 , the second tank 142 , and the third tank 144 as they flow through the mixing chamber and ultimately out of the nozzle portion 110 .

In the embodiment shown in FIG. 14, each of the first valve 176, the second valve 178, and the third valve 180 has a stem portion and a valve hole formed through the stem portion so that when the valve is in the open position, the Fluid communication between each respective first tank 140 , second tank 142 , third tank 144 and mixing chamber 182 is provided. Specifically, when the trigger 106 is actuated, the trigger output 160 is caused to move the cam member 162 horizontally and place the first cam surface 170, the second cam surface 172, the third cam surface 174 against the first follower 171, the second follower 173, the third follower 175, the mixing manifold 146 is pressed vertically downward. The downward vertical movement of the mixing manifold 146 causes the valve stem portion to move downward, simultaneously moving the first valve 176, the second valve 178, and the third valve 180 to the open position. When all of the first valve 176, the second valve 178, the third valve 180 are moved to the open position simultaneously, the contents of the first tank 140, the second tank 142, the third tank 144 can enter the mixing chamber 182 substantially simultaneously to Mixing is allowed.

The first tank 140, the second tank 142, and the third tank 144 may be disposed within the housing 102 of the decontamination device 100 and arranged such that the upper portion of the tanks may engage the respective valves. Specifically, the upper portion 151 of the first tank 140 may be configured to engage the first valve 176, the upper portion of the second tank 142 may be configured to engage the second valve 178, and the third tank 144 may be configured to engage the third valve 178.

The first valve 176 may have a first stem portion 188 having a first valve hole 189 formed therethrough that may provide a connection between the first tank 140 and the mixing chamber 182. fluid communication between. The second valve 178 may have a second stem portion 190 having a second valve hole 191 formed through the second stem portion, and the second valve hole 191 may provide a space between the second tank 142 and the mixing chamber 182 fluid communication. The third valve 180 may have a third stem portion 192 having a third valve hole 193 formed through the third stem portion, and the third valve hole 193 may provide a connection between the third tank 144 and the mixing chamber 182 fluid communication between. In some embodiments, the upper portion 151 , 153 , 155 of each respective first canister 140 , second canister 142 , third canister 144 may form valve orifices 194 , 195 , 196 or other inlets to receive or otherwise Each respective first valve 176 , second valve 178 , third valve 180 is engaged.

The size of each valve hole can vary from valve to valve and depends on the desired mixture quality. For example, in the embodiment shown in FIG. 14 , the first valve hole 189 formed through the first stem portion 188 may be relatively narrower than the second valve hole 191 formed through the second stem portion 190 . This relationship may be desirable where the mixture dispensed by the decontamination device 100 has a higher volume of material stored in the second tank 142 than the material stored in the first tank 140 . As a further example, the third valve 180 shown in FIG. 14 may include a restrictor orifice because the third valve bore 193 formed through the third stem portion 192 narrows near the mixing chamber 182 . It should be understood, however, that any of these types of valve orifices and others may be used in any combination to affect the mixture dispensed from the decontamination device 100 . It should also be understood that other types of device components may be used to control the proportion of material entering the mixing chamber 182 from the tank and the amount of material exiting the final nozzle 120 . For example, other embodiments may include induced vortices, pressure-regulated orifices, resistance orifices, and the like. The components and features described herein can add control over the proportions of mixed materials on a mass or volume basis, since in some embodiments, the dispensed materials can rely on tightly controlled mixing percentages.

FIG. 14 also shows the relationship between the mixing manifold 146 , the chamber insert 186 and the nozzle face 125 . Nozzle end 197 of chamber insert 186 and nozzle end 198 of mixing manifold 146 may engage nozzle face 125 to form a flow path between mixing chamber 182 and final nozzle 120 . Nozzle face 125 may include a generally cylindrical outer nozzle collar 121 that may receive nozzle end 198 of mixing manifold 146 . The nozzle face 125 can also include an inner nozzle collar 123 that is substantially concentric with the outer nozzle collar 121 that can receive the nozzle end 197 of the chamber insert 186 . In the embodiment shown in FIG. 14 , the mixing space 129 may be formed within the outer nozzle collar 121 and the nozzle end 198 of the mixing manifold 146 that may be in fluid communication with the mixing chamber 182 . Additionally, while the inner nozzle collar 123 may substantially surround the nozzle end 197 of the chamber insert 186 , it should be understood that at least a portion of the inner nozzle collar may allow fluid communication between the mixing space 129 and the final nozzle 120 . However, in some embodiments, the engagement between the nozzle end 197 of the chamber insert 186 and the inner nozzle collar 123 may restrict flow between the mixing space 129 and the final nozzle 120 at least somewhat. In some embodiments, this restriction may allow the material released from the first tank 140 , the second tank 142 , and the third tank 144 to flow through the mixing chamber 182 and converge in the mixing space 129 as improvements occur within the mixing space 129 . the mix of. In other words, in some embodiments, material released from the tank closest to the nozzle portion 110 (eg, the third tank 144 ) may be released from tanks further away from the nozzle portion (eg, the first tank 140 or the second tank 142 ) Before the released material reaches the mixing space 129 , the restrictive engagement between the nozzle end 197 of the chamber insert 186 and the inner nozzle collar 123 of the nozzle face 125 can slow the dispersion of the material, thereby allowing the material to disperse before being ejected from the final nozzle 120 Opportunity for more thorough mixing. Another view of the relationship between the mixing manifold 146 , the chamber insert 186 and the nozzle face 125 is also shown in FIG. 15 with the pull safety device 118 above the nozzle face 125 .

Thus, in the embodiment shown in FIGS. 14 and 15, upon actuation of the trigger 106 by the user, the material stored in the respective first tank 140, second tank 142, third tank 144 may be released to the In the mixing chamber 182 , flows into the mixing space 129 and exits as a mixture through the final nozzle 120 .

16 and 17 show the relationship between the pull safety device 118 and the trigger 106 . In some embodiments, pulling the safety device 118 may prevent activation of the trigger 106 when it is in place. Specifically, the tail portion 126 of the pull safety device 118 can include a tail tip 132 that can fit through a tip aperture 130 formed in the front handle arm 112 to engage the distal end 149 of the first trigger arm 148 . In some embodiments, a safety hole 147 may be formed in the distal end 149 of the first trigger arm 148 to receive the tail tip 132 . In such an embodiment, the tail tip 132 may prevent the first trigger arm 148 from moving when the user applies pressure to the trigger input 158 . Such a safety mechanism may prevent accidental or unintentional activation and dispensing of materials stored within decontamination device 100 . However, when the user wants to use the decontamination device 100 , the user can remove the pull safety device 118 , eg, via pulling the pull tab 122 . Pulling the pull tab 122 can remove the center cap 124 from its position above the nozzle face 125, and can further remove the tail tip 132 from the safety hole 147 in the trigger. This embodiment of the pull safety device 118 and trigger 106 can help prevent improper activation of the device because the pull safety device can be configured such that the tail tip 132 cannot be removed from the safety hole 147 and tip aperture 130 until the center The cap 124 has been pulled away from the final nozzle 120 . However, in other embodiments, it is contemplated that the tail tip 132 and center cap 124 may be removed separately.

In some embodiments, as best shown in FIG. 17 , the tail tip 132 may include at least one finger 133 , each of which may also include a finger protrusion 135 . In such an embodiment, the safety hole 147 may be formed relatively wider near its end than at its entrance to accommodate the fingers 135 when the tail tip 132 is seated within the safety hole. A gap may be formed between the fingers 133 such that when the tail tip 132 is removed from the safety hole, the angled walls of the safety hole 147 rest against the finger protrusions 135, forcing the distal ends of the fingers 133 inward. This inward movement of the fingers 133 may allow the tail tips 132 to be removed from the safety holes 147 when the user pulls with sufficient force to overcome the fingers' tendency to resist inward movement. In some embodiments, once the tail tip 132 is fully disengaged from the safety hole 147, the resiliency of the fingers 133 can force the distal end back to the original expanded position. In such an embodiment, the fingers 133 may expand to a width greater than the width of the entrance to the safety hole 147, thereby preventing or limiting the ability to re-insert the tail tip 132 into the safety hole. In such an embodiment, a potential user of the decontamination device 100 may know that the device may not be complete because the pull safety device 118 has been previously removed. In some embodiments, the fingers 133 may not spring back into place, but instead be permanently deformed upon removal from the safety hole 147 . In such an embodiment, the tail tip 132 may be made weak within the safety hole 147 because the fingers 135 do not rest outwardly against the walls of the safety hole. Thus, in such an embodiment, potential users may also be alerted of the fact that the pull safety device 118 has been previously removed and the canister may be full.

Figure 18 shows the decontamination device 100 in the dispensing position, where the trigger 106 has been moved from the passive position (eg, Figure 13) to the dispensing position. As shown, the trigger output 160 may abut the trigger end 164 of the cam member 162, thereby moving the cam member horizontally from the passive position toward the nozzle portion 110 to the dispensing position. When the cam member 162 moves toward the nozzle, the first cam surface 170, the second cam surface 172, the third cam surface 174 may press down the first follower 171, the second follower 173 and the third follower, respectively 175, which can move the mixing manifold toward the first tank 140, the second tank 142, the third tank 144 from the passive position to the dispensing position. Downward movement of the mixing manifold 146 may open the first valve 176, the second valve 178, and the third valve 180, allowing the material in the respective first tank 140, second tank 142, third tank 144 to enter the mixing manifold , mix and dispense through the nozzle.

FIGS. 19 and 20 illustrate an alternate embodiment of the pull safety device 218 having a tail tip 232 that can be used with the trigger 206 forming a safety hole 247 at its distal end 249 . In this embodiment, the tail tip 232 may include a first finger 233 and a second finger 234 with a gap 235 formed between the two fingers. The safety hole 247 may be formed relatively wider near its ends than at its entrance to accommodate the first and second fingers 233, 234 when the tail tip 232 is seated within the safety hole. At least one of the first finger 233 or the second finger 234 may include a finger cam 236 . In some embodiments, when the tail tip 232 is pulled out of the safety hole 247, the pressure of the safety hole wall on the finger cam 236 can force the second finger 234 toward the first finger 233, thereby allowing the user to Pulling with sufficient force to overcome the fingers' tendency to resist inward movement narrows the gap 235. In some embodiments, once the tail tip 232 is fully disengaged from the safety hole 247, the resiliency of the first finger 233, the second finger 234 can force the distal end back to the original expanded position. In such an embodiment, the first finger 233, the second finger 234 may expand to a width greater than the width of the entrance to the safety hole 247, thereby preventing or limiting the ability to re-insert the tail tip 232 into the safety hole . In such an embodiment, a potential user of decontamination device 100 may know that the device may not be complete because pull safety device 218 has been previously removed. In some embodiments, the first finger 233 , the second finger 234 may not spring back into place, but be permanently deformed upon removal from the safety hole 247 . In such an embodiment, it may be possible to make the tail tip 232 weak within the safety hole 247 because the finger cam 236 and the first and second fingers 233, 234 do not rest outwardly against the walls of the safety hole superior. Thus, in such an embodiment, potential users may also be alerted of the fact that the pull safety device 218 has been previously removed and the canister may be full.
