[0021] According to the present disclosure, a battery box assembly having a flexible circuit spring member is provided. Also provided herein is a wearable patient monitor including such a battery box assembly with features that extend its life cycle. As described herein, the battery box assembly is configured to provide one or more battery contacts that contact and / or otherwise engage with terminals of removable batteries when the batteries are inserted into the battery box assembly. These battery terminals cause the battery contacts to bend, thereby causing fatigue not only to the resilient spring member but also to the flexible circuit each time a battery is inserted, removed, and / or replaced. According to the present disclosure, it has been discovered that by using various combinations of air chambers, cavities, and / or reinforcing portions as described herein, the durability and expected life of the battery contacts of the battery box assembly can be dramatically improved. Furthermore, it has been discovered that the cavities and / or other features described herein can be adjusted to balance otherwise uneven battery forces due to linear battery distribution, thereby making the battery insertion and / or removal process easier and more consistent for the user.

[0022] 1 , an exploded view of a battery box assembly 100 according to an aspect of the present disclosure is shown. According to the present disclosure, the battery box assembly 100 includes at least a box casing 102, a flexible circuit 104, and a resilient spring member 112. In a further embodiment, the battery box assembly 100 may include a shroud member 114. In yet another embodiment, the battery box assembly 100 may also include a second resilient spring member 108 and / or a bumper member 110.

[0023] In an embodiment, the box casing 102 of the battery box assembly 100 includes one or more sidewalls that define a receiving area 116 dimensioned to receive one or more removable batteries. As shown in FIGS. 2A and 2B , the battery box assembly 100 is a battery lid assembly 100 having a box casing 102 that includes sidewalls 118A, 118B, 118C, and 118D and a floor (i.e., backing) 120. The sidewalls 118A, 118B, 118C, and 118D and the floor 120 may 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. A battery (not shown) may preferably extend longitudinally between the sidewalls 118A and 118D. In some embodiments, the side walls 118A, 118B, 118C, 118D and floor 120 may include one or more spacers 122, 124 to space the cells apart.

[0024] In an embodiment, the box casing 102 of the battery box assembly 100 is formed from a rigid material, such as a medical-grade thermoplastic polymer, that has high impact and chemical resistance and low moisture absorption. In certain embodiments, the box casing 102 of the battery box assembly 100 can comprise medical-grade polycarbonate, polypropylene, polyethylene, or the like, and / or combinations thereof.

[0025] 1 and 3 , the flexible circuit 104 of the battery box assembly 100 is above the box casing 102 and extends inside the box casing 102. The flexible circuit 104 may include one or more alignment notches 310, 312 that align the flexible circuit 104 with alignment protrusions on the box casing 102. In embodiments, the flexible circuit 104 connects a battery to an associated electronic device. For example, the flexible circuit 104 may include conductive traces (i.e., electrical circuitry) that connect a battery and provide power to the associated electronic device. In embodiments, the flexible circuit 104 may include one or more conductive strips (i.e., portion 400 shown in FIG. 4 ) configured to contact terminals of corresponding removable batteries, thereby forming contacts 301 with one or more batteries for transmitting power to the associated electronic device. The flexible circuit 104 may include one conductive strip 400 or multiple conductive strips 400 (e.g., two, three, or more). In the example of FIG. 3, the flexible circuit 104 includes at least three conductive strips 400 .

[0026] In further embodiments, the flexible circuit 104 delivers power from one or more removable batteries through one or more conductive strips 400 to the associated electronic device via one or more conductive pads 302. In some embodiments, the flexible circuit 104 of the battery box assembly 100 may include at least one conductive pad 302, or may include multiple conductive pads 302. As shown in FIG. 3 , the flexible circuit 104 of the battery box assembly 100 includes five conductive pads 302.

[0027] Referring to FIG. 4, a flattened or unfolded flexible circuit 104 is shown in accordance with aspects of the present disclosure. In embodiments, the flexible circuit 104 may include a flexible substrate 401 having one or more resilient conductive strips 400 that define contact points 301 with one or more batteries. Conductive traces 403 may extend through the interior and / or along the rear surface of the flexible circuit 104. In some embodiments, the flexible circuit 104 is formed from multiple layers, including, but not limited to, one or more insulating layers, one or more conductive layers, etc.

[0028] In embodiments, one or more conductive traces / layers 403 may be etched to define the conductive strips 400 and / or conductive pads 302. The conductive layer 403 is suitably gold, copper, or the like. As described herein, the conductive traces interconnect the plurality of conductive strips 400 and the battery to provide power in the form of electricity. In further embodiments, the conductive strips 400 and / or conductive pads 302 may be plated onto or embedded in the flexible circuit 104 to form contacts 301 or power contacts 302 with one or more battery cells. For example, the conductive strips 400 and / or conductive pads 302 may be plated with a conductive material, such as gold.

[0029] The insulating layer is suitably disposed around the conductive layers, and, where appropriate, between the conductive layers, such that only the conductive strips 400 and / or conductive pads 302 are exposed. In embodiments, for example, the flexible circuit 104 may include one or more non-conductive portions 405 between one or more conductive strips 400. In some embodiments, each non-conductive portion 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 portions 405 are suitably formed from a polymeric material, such as, for example, a polyamide polymer.

[0030] An adhesive layer on or applied to the backside of the flexible circuit 104 adheres the flexible circuit 104 to the floor 120 of the box casing 102 along the outside of the box casing 102, around the top edges of the side walls 118A, 118B, 118C, 118D, and / or along the inside of the side walls 118A, 118B, 118C, 118D. In embodiments, the adhesive may be selected to provide a fluid-tight seal between the flexible circuit 104 and the box casing 102 and prevent microorganisms from entering between the box casing 102 and the flexible circuit 104. The adhesive may be selected to be resistant to chemical disinfectants. In other embodiments, alternative and / or additional techniques may be used, such as, for example, solvent welding, heat bonding, etc.

[0031] As described above, the flexible circuit 104 of the battery box assembly 100 can be folded outside the box casing 102 and extend into the receiving area 116 of the box casing 102. For example, as shown in FIG. 3 , the flexible circuit 104 of the battery box assembly 100 can include a folded portion 304 that is folded over at least one side wall 118C of the box casing 102.

[0032] In further embodiments, the flexible circuit 104 may further include one or more additional folds, such as, for example, folds 306, 308. The folds 304, 306 are configured to contact the terminals of one or more batteries to provide power to an associated electronic device via the traces and conductive regions 301, 302 of the flexible circuit 104. In certain embodiments, each of the conductive strips 400 may be suitably positioned on a common side of the flexible circuit 104 such that the conductive strips 400 are exposed on the inside of the folds 304 of the flexible circuit 104.

[0033] As described above, the battery box assembly 100 includes a resilient spring member 112 disposed between the sidewall 118A of the box casing 102 and the outwardly facing surface of the flexible circuit 104. For example, in accordance with aspects of the present disclosure, the position of the flexible circuit 104 relative to the resilient spring member 112 is shown in FIG. 5. As shown, the flexible circuit 104 includes a first surface 502, a second surface 504, and a folded portion 306. In an embodiment, the resilient spring member 112 includes a rib 506 that extends from the surface 134 (shown in FIG. 1) of the resilient spring member 112 and follows the contours of the folded portion 306 of the flexible circuit 104. In an embodiment, the flexible circuit 104 can be positioned within the receiving area 116 of the box casing 102 such that a first surface 502 of the flexible circuit 104 faces inward toward the open volume of the receiving area 116, while a second surface 504 of the flexible circuit 104 faces outward toward the box casing 102 itself.

[0034] 6 and 7, further embodiments of the resilient spring member 112 will be described.

[0035] In embodiments, the resilient spring member 112 includes one or more surfaces 602 having one or more cavities 604 disposed therein. In some embodiments, the one or more cavities 604 may be disposed within depressions 606 also defined in the one or more surfaces 602. The depressions 606 of the resilient spring member 112 may include one or more solid portions 608 between and / or adjacent to each of the cavities 604. In certain embodiments, each of the solid portions 608 may be adjacent to at least one of the one or more conductive strips 400 of the flexible circuit 104. Each of the solid portions 608 may be tuned to balance otherwise unequal battery forces that may exist due to the linear distribution of the batteries. In other words, the solid portions 608 may be configured to provide a customized counterforce that helps secure each battery within the receiving area 106.

[0036] 5 and 6, the resilient spring member 112 includes a recess 606 having two cavities 604, with solid portions 608 flanking either side of the cavities 604 such that each solid portion 608 is adjacent to a corresponding conductive strip 400. In other words, each of the cavities 604 of the resilient spring member 112 is adjacent to a non-conductive portion 405 of the flexible circuit 104.

[0037] 6 and 7 , each of the one or more cavities 604 in the resilient spring member 112 can form a thin layer portion 702 of the resilient spring member 112 adjacent to the non-conductive portion 405 of the flexible circuit 104. In further embodiments, the resilient spring member 112 can also include one or more reinforcing portions 610 within the recesses 606. In embodiments, each of the one or more reinforcing portions 610 is tuned to balance otherwise unequal battery forces present due to the linear distribution of the batteries. In other words, the reinforcing portions 610 can be configured to provide a customized counterforce that helps secure each battery within the receiving area 106.

[0038] 7, the reinforcement portions 610 include additional material beyond the solid portions 608. In certain embodiments, each reinforcement portion 610 is positioned adjacent to at least one of the one or more conductive strips 400 of the flexible circuit 104. In embodiments, each reinforcement portion 610 is positioned between two adjacent cavities 604.

[0039] In an embodiment, the surface 602 of the resilient spring member 112 also includes a sealing bead 612 extending outwardly from the surface 602. The sealing bead 612 is configured to surround or otherwise bound one or more of the cavities 604 and recesses 606 of the resilient spring member 112. For example, as shown in FIG. 6 , the resilient spring member 112 includes a first set of two cavities 604 surrounded by a first sealing bead 612.

[0040] In an embodiment, the resilient spring member 112 may be secured between the sidewall 118A of the box casing 102 and the outer surface 504 of the flexible circuit 104, and the one or more cavities 604 and / or recesses 606 may include a concave surface that defines an open volume (i.e., an air chamber) between the sidewall 118A and the resilient spring member 112. In a further embodiment, the sealing bead 612 of the resilient spring member 112 is configured to provide continuous contact with the inner surface (surface 132 shown in FIG. 2A ) of the sidewall 118A of the box casing 102 such that fluids and / or debris are not trapped within the air chambers formed therein. Thus, when assembled, the sealing bead 612, solid portion 608, cavity 604, and reinforcing portion 610 of the resilient spring member 112 form one or more air chambers with the sidewall 118A of the box casing 102.

[0041] In embodiments, one or more of these portions of the resilient spring member 112 may comprise a flexible and / or compressible material, such as, for example, silicone, and may be formed by a process such as, for example, injection molding. In certain embodiments, at least one of the rib portion 506 and the reinforcement portion 610 of the resilient spring member 112 is formed from a flexible and / or compressible material, such as, for example, silicone.

[0042] In an embodiment, the resilient spring member 112 may be secured between the sidewall 118A of the box casing 102 and the outer surface 504 of the flexible circuit 104 by the shroud member 114. In other words, the resilient spring member 112 and the folded portion 306 of the flexible circuit 104 are secured to the box casing 102 by the shroud member 114. Referring to FIG. 8 , for example, the shroud member 114 may include one or more fastening mechanisms 802, 804 configured to mate or fit into one or more complementary slots provided in the box casing 102.

[0044] In a further embodiment, the battery box assembly 100 may be hingedly attached to one of the side walls 118A, 118B, 118C, 118D of the box casing 102 such that the battery box assembly 100 rotates about a fixed axis relative to the remainder of the patient monitor 900. For example, as shown in Figures 2A and 2B, the exterior surfaces of the side walls 118A, 118D include protrusions 130 that engage the housing of the patient monitor 900 and allow the battery box assembly 100 to open, thereby allowing any batteries to be inserted, removed, and / or replaced.

That is, these and similar terms include the case where one or more intermediate elements or components are used to connect the two elements or components. However, when an element or component is said to be "directly connected" to another element or component, this only includes the case where the two elements or components are connected to each other without any intermediate or intervening elements or components.

[0054] In the claims and the specification, all transitional phrases such as "having," "including," "carrying," "having," "including," "including," "holding," "consisting of," and the like, are to be understood to be open-ended, i.e., meaning inclusive of, but not limited to. Only the transitional phrases "consisting of" and "consisting essentially of" are closed or semi-closed transitional phrases, respectively.
