The breath path 424 can start at the entrance of the mouthpiece 114, travel through the mouthpiece 112, and exit the mouthpiece at 634. The aperture from the distal end 114 of the breath path can extend through the mouthpiece to the exit at 634. The breath path through the mouthpiece 112 can be linear, such as to allow for easy cleaning of portion of the mouthpiece 112 that defines the breath path. The distal end of the mouthpiece 112 (the portion that goes between a user’s lips or defines the distal end of the breath path) can have a non-circular cross-section. In some embodiments, the distal end of the mouthpiece 112 can have a cross-section that helps form a seal between the user’s lips and the mouthpiece 112. For example, the distal end of the mouthpiece 112 can have an oval cross-section. In some embodiments, the distal end of the mouthpiece 112 can have a cross section that is rectangular with rounded corners, which can also be referred to as a stadium shape. In various embodiments, the mouthpiece 112 can be intended to be reused. In many scenarios a user can wash a mouthpiece to ensure that it is clean. The mouthpiece 112 can be made from materials that are dishwasher safe. In some embodiments the mouthpiece 112 can be made from silicone. In some embodiments, the mouthpiece 112 can be made from a polymer. The mouthpiece 112 can include at least one attachment element, such as the magnets 630 shown in FIG.6. In some embodiments, the mouthpiece 112 can include
PDSD No.365.2002WOU1 two, three, four, or more magnets 630. The one or more magnets 630 can be over- molded into the mouthpiece 112, such as to ensure the magnets 630 remain in place and to allow for easy cleaning of the mouthpiece 112. The magnets 630 can be disposed within the mouthpiece 112, such that the are not visible. The magnets 630 can be disposed within the mouthpiece 112, such that they are flush with or inset within the mouthpiece which can result in a flat bottom surface of the mouthpiece 112. In various embodiments, the mouthpiece and the housing cap can define alignment features to facilitate attachment of the mouthpiece to the housing cap in the correct orientation. Options for alignment features include one or more recesses on the mouthpiece aligned with one or more mating projections on the housing cap, or vice versa. FIGS.6-7 show the mouthpiece 112 defining a recess 632. The recess 632 can be aligned with a projection 840 in the housing cap 110 (shown in FIG.8) to ensure proper alignment of the mouthpiece 112 in the device 100. In some embodiments, such as those without the recess 632, the mouthpiece 112 can have at least one axis of symmetry. In some embodiments, such as those without recess 632 and with a centered exit 634, the mouthpiece 112 can have at least two axes of symmetry. Housing Cap FIG.8 shows a top perspective view of a housing cap 110 in accordance with various embodiments herein. FIG.9 shows a bottom perspective view of the housing cap 110.

The housing cap 110 can direct the breath path 424 from the exit of the mouthpiece 634 in a non-linear direction. The housing cap 110 can direct the breath path 424 toward and then through a trough or filter 426 to remove any saliva or other non-desirable particulate from the breath sample. When the breath path impacts the trough and is forced to change directions, saliva and particulate are likely to come to rest in the trough or filter 426. The housing cap 110 can further direct the breath path 424 through an aperture 428 in the housing cap 110 towards the electronics package for analysis. In various embodiments, the filter 426 can be exposed when the mouthpiece 112 has been removed from or is not connected to the housing cap 110. In one embodiment, the exposed filter 426 has an open trough configuration that can be
PDSD No.365.2002WOU1 easily wiped or otherwise cleaned by a user when the mouthpiece 112 is not connected to the housing cap 110. In various embodiments, the housing cap 110 can include a projection 840. The projection 840 can align with a recess 632 defined by the mouthpiece 112. The alignment of the projection 840 with the recess 632 can ensure proper alignment of the mouthpiece 112 in the device 100. The housing cap 110 can be fixed within the housing 102, such that it is known the housing cap 110 has the proper alignment. In some embodiments, the projection and recess can be switched, such that the mouthpiece 112 includes a projection and the housing cap 110 defines a recess. In many embodiments, the housing cap 110 is not symmetrical along a longitudinal axis, such that it does not include a projection on both sides of the filter. Similarly, in some embodiments, the mouthpiece 112 only includes a recess on one side in order to prevent mating the two components 110, 112 in a non-desired arrangement. In some embodiments, the housing cap 110 can include one or more attachment elements, such as magnets 838. The magnets 838 can be aligned with the magnets 630 included in the mouthpiece. In various embodiments, the magnets 838 can be positioned within the housing cap 110 with the same spacing as the magnets 630 in the mouthpiece 112. The housing cap 110 can include the same number of magnets as the mouthpiece 112. FIG.10 shows the bottom surface of the housing cap 110. The aperture 428 can extend through the housing cap 110 to allow the breath sample traveling along the breath path 424 to travel through the housing cap 110 and towards the electronics package for analysis. FIG.11 shows a top perspective view of an alternative housing cap 1110 embodiment. FIG.12 shows a bottom view of the housing cap 1110. In some embodiments, the housing cap 1110 can define a portion of the breath path 424 that is linear with the breath path defined by the mouthpiece 112, such as shown in FIG.11, where the aperture 428 defined by the housing cap 1110 can be aligned with the exit 634 from the mouthpiece 112. In some embodiments, the housing cap can include one or more fastener apertures 1142, such as a screw aperture, to secure the housing cap in the housing 102. In other embodiments, an adhesive or epoxy can be used to secure the housing cap within the housing 102.
PDSD No.365.2002WOU1 Lid FIGS.13-15 show stages of the device 100 transitioning from a closed state to an open state. The device 100 is in a closed state when the lid 106 encloses the interior volume of the housing 102 as shown in FIG.13. The device is in a partially open state when the lid 106 is neither in its fully open or fully closed position as shown in FIG.14. The device is opened when the lid 106 is in the fully open position as shown in FIG.15. In some embodiments, the lid 106 can rotate further to a more open position than is shown in FIG.15. In some embodiments, in the closed state, there can be multiple magnets keeping the lid 106 in the closed position. Housing magnets 103, 107 can keep the lid 106 in the closed position. As discussed above, the device 100 can include a double hinge to rotatably connect the lid 106 with the main body 104 of the housing 102, such as to facilitate a greater range of opening. The double hinge can include a first hinge 1344, a second hinge 1346, and a hinge magnet 216 disposed between the first hinge 1344 and the second hinge 1346. The first hinge 1344 can be disposed in the lid 106. The second hinge 1346 can be disposed in the main body 104. To initially start the opening process, housing magnets 103, 107 can be separated from each other by rotating the lid 106 around the first hinge 1344. The hinge magnet 216 and the housing cap magnet 218 can remain attached until first hinge 1344 has reached an open position, such as shown in FIG 14. The hinge magnet 216 and the housing cap magnet 218 can ensure that rotation around the first hinge 1344 takes place before rotation around the second hinge 1346, such as to prevent interference between a back portion of the lid 106 and a back portion of the main body 104. The lid 106 can be further rotated away from its closed position to its open position, such an action can separate the hinge magnet 216 from the housing cap magnet 218. Once the hinge magnet 216 has been separated from the housing cap magnet 218, the lid can rotate around the second hinge 1346. FIG.15 shows the lid 106 in the open position after separating the housing magnets 103, 107, followed by rotating around the first hinge 1344, separating the hinge magnet 216 from the housing cap magnet 218, and finally rotating around the second hinge 1346.
