[0031] According to the present disclosure, a battery compartment assembly having a flexible circuit spring member is provided. A wearable patient monitor including such a battery compartment assembly having features that extend its life cycle is also provided herein. As described herein, the battery compartment assembly is configured to provide one or more battery contacts that contact and / or otherwise engage the terminals of a removable battery when the battery is inserted into the battery compartment assembly. These battery terminals cause the battery contacts to flex, thereby creating wear in the flexible circuit and the resilient spring member whenever the battery is inserted, removed, and / or replaced. According to the present disclosure, it has been found that various combinations of air chambers, hollow cavities, and / or reinforcing sections as described herein can significantly improve the durability and life expectancy of the battery contacts of the battery compartment assembly. Additionally, it has been found that the cavities and / or other features described herein can be adjusted to balance other unequal battery forces resulting from the linear distribution of the batteries, thereby making the process of inserting and / or removing the battery easier and more consistent for the user.

[0032] Go to Figure 1 , a exploded view of a battery compartment assembly 100 in accordance with aspects of the present disclosure is shown. According to the present disclosure, the battery compartment assembly 100 at least includes a compartment housing 102, a flexible circuit 104, and a resilient spring member 112. In some additional embodiments, the battery compartment assembly 100 may include a shield member 114. In still other embodiments, the battery compartment assembly 100 may further include a second resilient spring member 108 and / or a buffer member 110.

[0033] In some embodiments, the compartment housing 102 of the battery compartment assembly 100 includes one or more side walls defining a receiving area 116 sized to receive one or more removable batteries. As Figure 2A and Figure 2B shown, the battery compartment assembly 100 can be a battery door assembly 100 having a compartment housing 102 including side walls 118A, 118B, 118C, 118D and a bottom plate (i.e., backing) 120. The side walls 118A, 118B, 118C, 118D and the bottom plate 120 can define the receiving area 116 such that the receiving area 116 is configured to receive one or more batteries, including but not limited to one or more AA batteries, AAA batteries, and / or rechargeable batteries. The battery (not shown) can preferably extend longitudinally between the side wall 118A and the side wall 118D. In some embodiments, the side walls 118A, 118B, 118C, 118D and the bottom plate 120 may include one or more spacers 122, 124 to space the batteries apart.

[0034] In some embodiments, the housing shell 102 of the battery compartment assembly 100 can be formed of a rigid material, such as a medical-grade thermoplastic polymer having high impact resistance, chemical resistance, and low hygroscopicity. In a specific embodiment, the housing shell 102 of the battery compartment assembly 100 can include medical-grade polycarbonate, polypropylene, polyethylene, etc. and / or combinations thereof.

[0035] Turn to Figure 1 and Figure 3 , the flexible circuit 104 of the battery compartment assembly 100 can extend over and into the housing shell 102. The flexible circuit 104 can include one or more alignment cuts 310, 312 that align the flexible circuit 104 with alignment protrusions of the housing shell 102. In some embodiments, the flexible circuit 104 connects the battery to an associated electronic device. For example, the flexible circuit 104 can include conductive traces (i.e., circuits) that connect the battery and supply power to the associated electronic device. In some embodiments, the flexible circuit 104 can be used as one or more conductive strips (i.e., Figure 4 the section 400 shown) configured to contact corresponding removable battery terminals, thereby forming one or more battery contacts 301 for delivering power to the associated electronic device. The flexible circuit 104 can include one conductive strip 400 or can include multiple conductive strips 400 (e.g., two, three, or more than three, etc.). In Figure 3 the example of, the flexible circuit 104 includes at least three conductive strips 400.

[0036] In still other embodiments, the flexible circuit 104 supplies power from one or more removable batteries to an associated electronic device via one or more conductive pads 302 through one or more conductive strips 400. In some embodiments, the flexible circuit 104 of the battery compartment assembly 100 can include at least one conductive pad 302, or can include multiple conductive pads 302. As Figure 3 shown, the flexible circuit 104 of the battery compartment assembly 100 includes five conductive pads 302.

[0037] Referring to Figure 4 , a flat or unfolded flexible circuit 104 is shown in accordance with aspects of the present disclosure. In some embodiments, the flexible circuit 104 can include a flexible substrate 401 having one or more resilient conductive strips 400 that define one or more battery contacts 301. Conductive traces 403 can extend through the interior of the flexible circuit 104 and / or along the back surface of the flexible circuit 104. In some embodiments, the flexible circuit 104 can be formed of multiple layers (including but not limited to one or more insulating layers, one or more conductive layers, etc.).

[0038] In some embodiments, one or more conductive traces / layers 403 may be etched to define conductive strips 400 and / or conductive pads 302. The conductive layer 403 is suitably gold, copper, etc. As described herein, the conductive traces interconnect the plurality of conductive strips 400 and the battery to provide electrical power. In some additional embodiments, the conductive strips 400 and / or conductive pads 302 may be plated onto or snapped into the flexible circuit 104 to form one or more battery contacts 301 or power contacts 302. For example, the conductive strips 400 and / or conductive pads 302 may be plated with a conductive material such as a gold material.

[0039] The insulating layer is suitably placed around the conductive layer and, where appropriate, between the conductive layers such that only the conductive strips 400 and / or conductive pads 302 are exposed. In some embodiments, for example, the flexible circuit 104 may include one or more non-conductive segments 405 located between one or more conductive strips 400. In some embodiments, each non-conductive segment 405 may have a width (W) of at least about 1 mm, including from about 1 mm to about 5 mm, from about 2 mm to about 4 mm, from about 3 mm to about 4 mm, and / or combinations thereof. The insulating layer and / or non-conductive segments 405 are suitably formed of a polymeric material such as a polyamide polymer.

[0040] An adhesive layer located on or applied to the rear surface of the flexible circuit 104 may adhere the flexible circuit 104 to the bottom plate 120 of the cartridge housing 102 along the exterior of the cartridge housing 102, around the top edges of the sidewalls 118A, 118B, 118C, 118D, and / or along the interior of the sidewalls 118A, 118B, 118C, 118D. In some embodiments, the adhesive may be selected to provide a fluid-tight seal between the flexible circuit 104 and the cartridge housing 102 to prevent microorganisms from entering between the cartridge housing 102 and the flexible circuit 104. The adhesive may be selected to resist chemical disinfectants. In other embodiments, alternative and / or additional techniques such as solvent welding, thermal bonding, etc. may be used.

[0041] As described above, the flexible circuit 104 of the battery cartridge assembly 100 may be folded on the exterior of the cartridge housing 102 and extend into the receiving area 116 of the cartridge housing 102. For example, as Figure 3 shown, the flexible circuit 104 of the battery cartridge assembly 100 may include a folding segment 304 that will be folded on at least one sidewall 118C of the cartridge housing 102.

[0042] In some other embodiments, the flexible circuit 104 may further include one or more additional folding segments, such as folding segments 306, 308. The folding segments 304, 306 may be configured to contact the terminals of one or more batteries and supply power to the associated electronic device through the traces and conductive regions 301, 302 of the flexible circuit 104. In a specific embodiment, each of the conductive strips 400 may be appropriately disposed on a common side of the flexible circuit 104 such that the conductive strips 400 are exposed on the inside of the folding segment 304 of the flexible circuit 104.

[0043] As described above, the battery compartment assembly 100 includes an elastic spring member 112 disposed between the side wall 118A of the compartment housing 102 and the outward-facing surface of the flexible circuit 104. For example, according to various aspects of the present disclosure, the position of the flexible circuit 104 relative to the elastic spring member 112 is shown in Figure 5 As shown. As shown, the flexible circuit 104 includes a first surface 502, a second surface 504, and a folding segment 306. In some embodiments, the elastic spring member 112 includes ribs 506 that extend from the surface 134 of the elastic spring member 112 ( Figure 1 shown) and follow the contour of the folding segment 306 of the flexible circuit 104. In some embodiments, the flexible circuit 104 may be disposed within the receiving area 116 of the compartment housing 102 such that the first surface 502 of the flexible circuit 104 faces inward toward the open volume of the receiving area 116, while the second surface 504 of the flexible circuit 104 faces outward toward the compartment housing 102 itself.

[0044] Refer to Figure 6 and Figure 7 for other aspects of the elastic spring member 112 described.

[0045] In some embodiments, the elastic spring member 112 may include one or more surfaces 602 having one or more hollow cavities 604 disposed therein. In some embodiments, the one or more hollow cavities 604 may be disposed within recesses 606 that are also defined within the one or more surfaces 602. The recesses 606 of the elastic spring member 112 may include one or more solid segments 608 between and / or adjacent to each of the hollow cavities 604. In a specific embodiment, each solid segment 608 may be adjacent to at least one of the one or more conductive strips 400 of the flexible circuit 104. Each solid segment 608 may be adjusted to balance other unequal battery forces present due to the linear distribution of the batteries. In other words, the solid segments 608 may be configured to provide a customized balancing force that helps to secure each battery within the receiving area 106.

[0046] In Figure 5 andFigure 6 In the example of, the resilient spring member 112 includes a recess 606 having two cavities 604, with adjacent solid segments 608 located on either side of the cavity 604 such that each solid segment 608 is adjacent to a corresponding conductive strip 400. In other words, each hollow cavity 604 of the resilient spring member 112 can be adjacent to a non-conductive segment 405 of the flexible circuit 104.

[0047] Referring to Figure 6 and Figure 7 , each of one or more hollow cavities 604 of the resilient spring member 112 can form a thinned portion 702 of the resilient spring member 112 adjacent to a non-conductive segment 405 of the flexible circuit 104. In some additional embodiments, the resilient spring member 112 can further include one or more reinforcing segments 610 located within the recess 606. In some embodiments, each of the one or more reinforcing segments 610 can be adjusted to balance other unequal cell forces present due to the linear distribution of the cells. In other words, the reinforcing segments 610 can be configured to provide a customized balancing force that helps hold each cell within the receiving area 106.

[0048] In Figure 7 's example, the reinforcing segment 610 includes additional material over the solid segment 608. In a specific embodiment, each reinforcing segment 610 can be arranged adjacent to at least one of one or more conductive strips 400 of the flexible circuit 104. In some embodiments, each reinforcing segment 610 is disposed between two adjacent hollow cavities 604.

[0049] In some embodiments, the surface 602 of the resilient spring member 112 further includes a sealing bead 612 extending outward from the surface 602. The sealing bead 612 can be configured to define or otherwise form a perimeter around one or more of the hollow cavities 604 and the recess 606 of the resilient spring member 112. For example, as Figure 6 shown, the resilient spring member 112 includes a first set of two hollow cavities 604 defined by a surrounding first sealing bead 612.

[0050] In some embodiments, the resilient spring member 112 can be fixed between the sidewall 118A of the cartridge housing 102 and the outer surface 504 of the flexible circuit 104, and one or more cavities 604 and / or recesses 606 can include a recessed surface that defines an open volume (i.e., an air chamber) between the sidewall 118A and the resilient spring member 112. In some additional embodiments, the sealing bead 612 of the resilient spring member 112 can be configured to provide an interface with the inner surface of the sidewall 118A of the cartridge housing 102 ( Figure 2AContinuous contact with the shown surface 132) prevents fluid and / or debris from being trapped in the air chambers formed therein. Thus, when assembled, the sealing flange 612, solid section 608, hollow cavity 604, and reinforcing section 610 of the resilient spring member 112 can form one or more air chambers with the side wall 118A of the cartridge housing 102.

[0051] In some embodiments, one or more portions of the resilient spring member 112 may include a flexible and / or compressible material, such as silicone, and may be formed by a process such as injection molding. In a particular embodiment, at least one of the rib portion 506 and the reinforcing section 610 of the resilient spring member 112 is formed of a flexible and / or compressible material such as silicone.

[0052] In some embodiments, the resilient spring member 112 may be fixed between the side wall 118A of the cartridge housing 102 and the outer surface 504 of the flexible circuit 104 via the shield member 114. In other words, the resilient spring member 112 and the folded section 306 of the flexible circuit 104 may be fixed to the cartridge housing 102 via the shield member 114. Referring Figure 8 to, for example, the shield member 114 may include one or more fastening features 802, 804 configured to connect or mate with one or more complementary slots provided in the cartridge housing 102.
