[0045] In some embodiments, the systems and methods described herein relate to a positionable over-bed cradle (e.g., baby tub) or tray with balanced support and / or a user-controlled release mechanism.

[0046] In some embodiments, the system includes a base, a support column, a pivotable support arm, a cradle or tray, a counterweight (also referred to as a counterweight system), and at least one release mechanism.

[0047] In some embodiments, the system may be structurally and / or functionally identical or similar to any system described in, for example, US11,116,330 entitled “Cradle”, granted September 14, 2021 (hereinafter referred to as the “330 Patent”), the entire contents of which are incorporated herein by reference. In some embodiments, the system and / or method steps described herein may be used in combination with and / or incorporated therein with any system, device, or method that is identical or similar to that described in the 330 Patent.

[0048] The base includes a horizontal surface and includes wheels for free movement on the floor, or wheels coupled to wheels for free movement on the floor. The base is rigidly connected to a support post. In some embodiments, the wheels of the base may be lockable. In some embodiments, the wheels provide rolling and steering motion, thereby allowing the base to move freely on the floor. In some embodiments, the base may include a storage system, which may include shelves for supplies in a previously unused space located beneath the cradle.

[0049] The support column is a vertical structure that connects to a base at its bottom and to a pivotable support arm at its top. The support column may include an adjustable height feature, allowing for changes in its length. The support column may include two parts: a first part or lower component (also referred to as a first section or lower portion) and a second part or upper component (also referred to as a second section or upper portion). The lower portion may be attached to the base. In some embodiments, the upper portion may be connected to the lower portion via a guide rail, allowing the upper portion to move up or down (e.g., along the guide rail) as desired by a user. In some embodiments, the height of the support column can be adjusted by releasing a locking mechanism and allowing the user to raise or lower the structure. In some embodiments, the support column may also include dampers and springs to counteract the weight of gravity and allow the user to raise and lower the structure with minimal force. Alternatively, in some embodiments, the movement of the support column may be controlled by a linear actuator or other electric mechanism. In some embodiments, the top of the support column may be pivotally connected to the support arm.

[0050] A pivotable support arm is a horizontal structure that connects a support column to a cradle or tray. The pivotable support arm may include at least one pivot located directly above the support column (e.g., the support arm is configured to rotate relative to the base about a pivot axis extending along the length of the support column), and in some embodiments, the pivotable support arm may include a second pivot located below the cradle or tray (e.g., at least a portion of the support arm is configured to rotate relative to the base about a second pivot axis different from the first pivot axis, such as a pivot axis passing through the center or central region of the cradle or tray). Figure 15 As shown. The second pivot allows the cradle or tray to pivot independently relative to the base. The pivotable support arm may include one or more release handles for actuating the locking mechanism. In some embodiments, a single release mechanism may control the release of multiple functions (e.g., pivoting, height adjustment, and wheel movement). In some embodiments, multiple release mechanisms may be used, each release lever responsible for releasing one or two functions independently of the other release handles. In some embodiments, the pivotable support arm may also include a transport handle for a clinician or user to push the system across the floor.

[0051] In some embodiments, the pivotable support arm further includes, for example, housing or coupled to a counterweight system. In some embodiments, the pivotable support arm may also have telescopic capability, allowing it to extend further over the bed during use and retract to a more compact position when needed. The pivotable support arm may also include a handle at the distal end of the support arm that facilitates easy positioning of the cradle or tray and support arm relative to the bed while the mother remains in bed.

[0052] A cradle is a basin-shaped structure designed to safely accommodate a newborn. The basin may be removably attached to a support arm. A tray may be a flat structure configured to provide a flat surface for supporting a newborn or other object. In some embodiments, the tray may include raised edges or outer boundaries. The tray may be removably attached to the support arm. The cradle and tray may be examples of retaining structures, such as structures configured to retain one or more objects.

[0053] The systems, apparatus, and methods described herein may include a counterweight system configured to bias weight away from the cradle or tray, allowing the cradle or tray to extend a greater distance away from the support column supporting the cradle or tray without causing instability of the system. In some embodiments, the counterweight system may include a fixed counterweight coupled (e.g., fixedly or rigidly attached) to a support arm of the system, such as... Figures 1A-1E As shown.

[0054] like Figures 1A-1E As shown, the system 100 for supporting the cradle may include a base, a support column, a support arm, a counterweight system, and the cradle. Figures 1A-1E The system shown may include components structurally and / or functionally similar to those of other systems for supporting a cradle described herein and / or in the '330 patent. A base may be coupled to a set of wheels or other transport elements (e.g., tracks, rollers, etc.) configurable to allow the system to move on a floor or other flat surface. A support column may extend upward or vertically from the base to a support arm. The support arm may be pivotable relative to the support column and / or the base. In some embodiments, the support arm may include a pivot located above the support column, and in some embodiments, the support arm may include a first pivot located above the support column and a second pivot located below the cradle. In some embodiments, the support arm may also have a telescopic capability, allowing it to extend further above the bed during use and retract to a more compact position when needed. The support arm may include one or more locking mechanisms for locking one or more pivots of the support arm and / or locking the extension or retraction of the support arm.

[0055] The cradle can be supported by a support arm. As described above, the cradle can be pivotally connected to the support arm. Figure 1A and Figure 1B The image shows a support arm in a first configuration, wherein the support arm is aligned with the base (e.g., the support arm and the base extend parallel to each other) and / or the cradle is centered relative to the base. Figure 1A A top view of the system in the first configuration is shown, and Figure 1B A side view of the system in the first configuration is shown. Figure 1C and Figure 1DThe diagram shows the support arm in a second configuration, where it has been pivoted relative to the base. In this pivoting configuration, the cradle can be positioned to one side of the base. Figure 1C A top view of the system in the second configuration is shown, and Figure 1D A side view of the system in a second configuration is shown. The cradle can be attached to the end of the support arm opposite to the support column. In other words, the cradle can be attached to the portion of the support arm that extends away from the support column. This positioning of the cradle allows it to be positioned above a patient's bed (e.g., a hospital bed). However, because the cradle is supported on the end of the support arm that is not directly above the support column and therefore cantilevered over the base, the weight of the cradle will bias the system's center of gravity toward the cradle. Therefore, to counteract this bias, the system may include a counterweight located at the end opposite the cradle. In some embodiments, the support arm may also be configured to be extended in length. For example, the length of the support arm when fully extended may be increased by up to about 2 feet or between about 1 foot and about 3 feet (inclusive of all subranges and values ​​in between) compared to the non-extended or retracted configuration. In such embodiments, the counterweight may also be used to counteract the larger torque load caused by the greater length of the support arm and the position of the cradle (e.g., farther from the support column).

[0056] like Figures 1A-1E As shown, the system includes a counterweight located at the end of a support arm opposite to the cradle, such that the cradle is positioned and / or coupled to a first end of the support arm, and the counterweight is positioned and / or coupled to a second end of the support arm. In some embodiments, the counterweight is located on a first portion of the support arm, and the cradle is located on a second portion of the support arm, the first and second portions of the support arm being configured to translate or move relative to each other. The first portion may be coupled to the support arm, while the second portion may be configured to translate relative to the first portion and thus extend or translate away from the support column. In some embodiments, the second portion may be positioned on a rail or guide and may translate relative to the first portion via the rail or guide. The second portion may be suspended above a base and / or floor, thereby allowing the cradle to be supported above the patient's bed. In some embodiments, the weight of the counterweight may cause the system's center of gravity to be closer to the center of the base when the cradle is in a retracted or stowed position relative to the base (e.g., when the cradle is partially, substantially, or completely positioned above the base, or when the support arm does not extend beyond the sides of the base), for example to reduce or minimize tipping or loss of stability. In some embodiments, the weight of the counterweight can cause the system’s center of gravity to be biased toward the counterweight when the cradle is in a retracted or stowed position relative to the base, for example, at the edge of the support column closest to the counterweight, slightly outside the support column toward the side with the counterweight, or generally closer to the side with the counterweight on the support arm than the side with the cradle.

[0057] Once the cradle is fully extended or deployed relative to the base (e.g., such that the cradle extends away from the base and is not positioned above it, or is positioned above the base with a smaller portion compared to its retracted or folded position), the system's center of gravity can be further shifted away from the base center. For example, in some embodiments, the center of gravity may be shifted to a position of the support column on the cradle side, a position facing the cradle outside the outline or periphery of the support column, or generally closer to the side of the support arm that includes the cradle rather than the side that includes the counterweight. Figure 1C and Figure 1D The first unfolded configuration of the cradle is shown, in which the support arms have been pivoted relative to the base, thus shifting the center of gravity further away from the center of the base. Figure 1E A second deployed configuration of the cradle is shown, in which the support arms have been extended, thus shifting the center of gravity further away from the base center, for example, along the direction toward the cradle. In some embodiments, in all configurations (e.g., all positions of the cradle relative to the base, such as the retracted or stowed position, the pivoted position, or the fully extended or deployed position), the center of gravity can be maintained within an area defined by the four wheels located on the base (e.g., within an area or volume spaced apart from the four wheels on the periphery) to maintain stability. Compared to a system without counterweight, the presence of counterweight and offsetting the counterweight away from the cradle allows the cradle to extend further above the mother's bed while minimizing or reducing the torque load in the support columns, and allows the system's center of gravity to be further away from potential unstable positions or ranges that could cause the entire system to tip over.

[0058] In some embodiments, the weight of the counterweight can counteract the torque, force, or effort exerted by the combined weight of the support arm, the cradle, the infant placed in the cradle, and / or additional forces exerted on the cradle by a patient or clinician during interaction with the infant and / or the cradle. In some embodiments, the weight of the counterweight can be sufficient to counteract the torque and force generated by the combined weight of the support arm, the cradle, the infant placed in the cradle, and / or additional forces exerted on the cradle by a patient or clinician during interaction with the infant and / or the cradle. The weight of the counterweight can be set or selected based on factors including, for example, the weight of the cradle, the position of the cradle (e.g., depending on whether the support arm is in a retracted or extended configuration), the weight of the support arm (and the distribution of the support arm weight along the length of the support arm), the position of the support arm connected to the support post, the position of the counterweight, the weight of the base (and its distribution), and the position of the wheels (e.g., the position where the base rests on the floor). In some embodiments, the counterweight may have a weight between about 5 kg and about 30 kg (inclusive of all values ​​and subranges therebetween) to adequately counteract the torque and forces generated by the combined weight of the support arm, the cradle, the infant placed in the cradle, and / or the additional forces exerted on the cradle by the patient or clinician during interaction with the infant and / or the cradle. For example, assuming an infant's average weight is between about 4 lbs and about 14 lbs (or between about 1.8 kg and about 6.4 kg) and the support arm's maximum extension in a fully extended configuration is up to about 2 feet, the counterweight may have a weight of about 25 kg or 55 lbs to counteract the torque and forces generated by the combined weight of the support arm, the cradle, and the infant placed in the cradle.

[0059] although Figures 1A-1E (And the other figures and embodiments below) show a cradle, but it is understood that such a system is not limited to cradles and can also be used for trays, for example Figure 22 The tray shown.

[0060] Figures 17-21 Views of an example cradle support system 1700 according to an embodiment are shown in various configurations. Figure 17 A top view of the cradle support system 1700 in a centered configuration is shown. Figure 18 A top view of the cradle support system 1700 in its first deployed configuration is shown. Figure 19 A side view of the cradle support system 1700 in a centered configuration is shown. Figure 20 A side view of the cradle support system 1700 in its first deployed configuration is shown. Figure 21 A top view of the cradle support system 1700 in a second deployed configuration is shown. The cradle support system 1700 can be used with other cradle support systems described herein (including, for example...). Figures 1A-1EThe cradle support system 100 shown is similar in structure and / or function.

[0061] As shown in the figure, the cradle support system 1700 may include a base 1702, a support arm 1704, a support column 1706, a release handle 1712, a counterweight 1710, and a cradle 1708. Similar to the base of system 100, the base 1702 includes a horizontal surface and includes wheels 1714 or is coupled to wheels 1714 for free movement on the floor. The base 1702 is coupled to the support arm 1706. The wheels 1714 can provide rolling and steering motion, thereby allowing the base to move freely on the floor. The support column 1706 extends vertically from the base 1702 to the support arm 1704. The support column 1706 may be configured to support the support arm 1704 relative to the base 1702 at a set height. The support column 1706 may be configured to adjust its height, for example, making it possible to adjust the height of the support arm 1704. In some embodiments, the support column may include one or more portions that can be adjusted relative to each other, for example, by releasing a locking mechanism, to adjust the height of the support column. The height of the support column can be adjusted to allow the system 1700 to adapt to beds of different heights; for example, the cradle 1708 can be positioned above beds of different heights.

[0062] like Figure 19 and Figure 20 As shown, the support arm 1702 may include a first end extending above the base 1702 and / or the floor and a second end located above the support column 1706. The support arm 1704 may be configured to pivot relative to the base 1702 via a pivotable connection to the support column 1706. For example, as... Figure 18 and Figure 20 As shown, the support arm 1704 can pivot to the right relative to the base 1702. In some embodiments, the support arm 1704 can similarly pivot to the left relative to the base 1702. In some embodiments, the support arm 1704 can pivot relative to the base 1702 at all angles (e.g., 360 degrees). Alternatively, in some embodiments, the support arm 1704 can be limited to pivoting to the right and / or left up to about 90 degrees, or between about 60 degrees and about 120 degrees in each direction (inclusive of all subranges and values ​​in between). A cradle 1708 can be disposed on the support arm 1704. In some embodiments, the cradle 1708 can be configured to pivot relative to the support arm 1704 via a second pivotable connection to the support arm 1704. In some embodiments, the support arm 1704 and the cradle 1708 can be configured to allow the cradle to extend into an unfolded configuration relative to a support post (e.g., translated a distance from or moved away from the support post), such as... Figure 21As shown. For example, the cradle 1708 can be configured to extend up to about 2 feet relative to the support post, including all subranges and values ​​in between. In some embodiments, the support arm can have two portions, one of which can extend from or away from the support post. In some embodiments, the cradle can be coupled to the support arm via one or more tracks that allow the cradle to extend from or translate away from the support post and / or support arm.

[0063] Similar to cradle support system 100, cradle support system 1700 may include a counterweight system, which includes a counterweight 1710. The counterweight 1710 may be coupled (e.g., fixedly attached) to an end of support arm 1704 opposite to the overhanging end of support arm 1704. In some embodiments, the weight of the counterweight 1710 may such that when the cradle is in a retracted or folded configuration relative to the base (e.g., when the cradle is partially, largely, or completely positioned above the base, or when the support arm is aligned with the base), the system's center of gravity may be approximately close to the center of the base, for example, to reduce or minimize tipping or loss of stability. For example, as Figure 17 As shown, when the cradle 1708 and support arm 1704 are aligned with the base, the system's center of gravity can be approximately located at the center of the base. When the support arm 1704 and cradle 1708 are deployed, for example, by pivoting to the right or left, or when the support arm 1704 is extended, the system's center of gravity shifts, for example due to the additional torque or moment exerted by the weight of the cradle (and the infant placed in the cradle) and / or the weight of the support arm relative to the support column. Therefore, to prevent the system from tipping over or losing stability, the counterweight 1710 can be set or selected to sufficiently counteract the torque, moment, or force exerted by the combined weight of the cradle, the infant, and / or the support arm.

[0064] Figure 18 and Figure 20 The first unfolded configuration of the cradle is shown, in which the support arms have been pivoted relative to the base and thus the center of gravity has been shifted away from the center of the base 1702. Figure 21A second deployed configuration of the cradle is shown, wherein the support arms have been extended and thus the center of gravity has been further shifted away from the center of the base, for example, along the direction in which the support arms 1704 have extended. In some embodiments, the center of gravity can be maintained within the system stability region in all configurations (e.g., all positions of the cradle relative to the base, such as a retracted or stowed position, a pivoted position, or a fully extended or deployed position). In some embodiments, the system stability region can be defined as the area within the four wheels of the base (e.g., within the area or volume spaced apart from the four wheels on the periphery). The presence of counterweight 1710 to counteract the weight of the cradle and / or the infant, compared to a system without counterweight, allows the cradle to extend further above the mother's bed while minimizing or reducing torque or force in the support columns, and keeps the system's center of gravity away from potentially unstable positions that could cause the system 1700 to tip over.

[0065] In some embodiments, the counterweight may be attached to the base (e.g., fixed to the base and / or housed within the base). Figure 2 As shown, in some embodiments, the counterweight may be placed on one side of the base (e.g., the left side of the base). When the cradle is in the retracted or folded position, the system's center of gravity will also be located on one side (e.g., the left side) of the center of the base and the system (also referred to as the trolley), but safely maintained within a boundary or perimeter (e.g., a rectangular perimeter) defined by the wheels (e.g., four wheels) that support the base and connect it to the floor, resulting in a stable system. In some embodiments, the system (e.g., support arms and / or support columns) may include physical rotation stops to mechanically limit the range of rotation of the support arms relative to the base, such that the support arms can only rotate toward the side of the trolley opposite to the side where the counterweight is located (e.g., the right side). When the cradle is fully extended (e.g., fully extended and rotated 90 degrees to the right) (e.g., the cradle is away from the maximum extended position of the base, for which balancing is required for stability), the center of gravity may shift to the right side of the base, but still remain safely maintained within the support boundary or perimeter defined by the wheels of the base. Compared to embodiments including counterweights incorporated in or attached to the support arms, systems with counterweights in the base have their weight distributed closer to the floor, and therefore can have improved stability. However, compared to support columns in systems with counterweights incorporated in or attached to the support arms, support columns in systems with counterweights in the base are subjected to and need to withstand greater torques from the extended cradle. In some embodiments, such as Figure 2As shown, the counterweight can be arranged on only one side of the base (e.g., entirely on one side of the central axis of the base, and opposite to the direction in which the support arm protrudes from the base when the system is in the deployed configuration). In some embodiments, the counterweight can be arranged in or attached to the base such that most of the counterweight is arranged on one side of the base (e.g., most of the counterweight is arranged on one side of the central axis of the base, and opposite to the direction in which the support arm protrudes from the base when the system is in the deployed configuration).

[0066] In some embodiments, such as Figures 3-7 As shown, the counterweight system can move together with the movement of the cradle. In some embodiments, the movable counterweight is coupled (e.g., attached) to the support arm at a position similar to that described above with reference to FIG1. ​​In some embodiments, the counterweight and the cradle (and their movement) are mechanically coupled together such that movement of the cradle causes a simultaneous movement of the counterweight. For example, in some embodiments, a user extending the cradle away from the support post causes the counterweight to extend away from the support post simultaneously (e.g., in the opposite direction). In some embodiments, the cradle, support arm, and counterweight are arranged such that when the counterweight is positioned closest to the support post (retracted), the cradle is also closest to the support post (retracted), and when the cradle extends away from the support post, the counterweight extends away from the support post (e.g., in the opposite direction). The mechanical coupling between the cradle and the counterweight may include a rack and pinion mechanism, a gear attached to the linkage arm, a series of mechanical couplings, and / or various other mechanical couplings.

[0067] By making the counterweight movable, a smaller counterweight can be used in conjunction with a fixed counterweight attached to the support arm or base (e.g., see Figure 1 and...). Figure 2 (Shown and described) The same or similar balancing effect. This is because a greater torque or moment can be generated by moving the counterweight to counteract the torque and force exerted by the weight of the cradle and / or the baby. By reducing the weight of the counterweight, the total weight of the system can be reduced, thereby making the system easier to move through corridors and within rooms while maintaining the same level of stability. In some configurations, the movable counterweight has a weight between about 5 kg and about 30 kg, and / or can be configured to move about 10 cm to about 30 cm when extended from the retracted position to the deployed position. In some embodiments, the cradle can be configured to move or extend a distance similar to the distance the counterweight moves. In some embodiments, the counterweight can move a greater distance than the cradle when the counterweight and cradle move between the retracted and deployed positions. In some embodiments, the counterweight can move a smaller distance than the cradle when the counterweight and cradle move between the retracted and deployed positions. In some embodiments, the counterweight can have a space for additional storage items (e.g., a defined chamber).

[0068] In some embodiments, the cradle may be connected to a rack that interacts with the cradle pinion. The cradle pinion may be connected via a shaft to a counterweight pinion, which meshes with the counterweight rack. The dimensions of the cradle pinion and the counterweight rack can be varied to change the relative motion of the counterweight with respect to the cradle. For example, Figure 6 A system including a cradle pinion is shown, the size of which is twice the size of the counterweight pinion, such that the counterweight moves a distance half the distance the cradle moves. In some embodiments, alternatively, the two pinions may have a 1:1 ratio, and / or the counterweight may be driven by the gears to move a greater distance than the cradle.

[0069] In some embodiments, such as Figure 8 As shown, the movable counterweight can be attached to the base (e.g., located within the base). For example, in some embodiments, the counterweight may have a retracted position arranged at the center of the base (e.g., aligned with the central axis of the base) and may be connected to the cradle via a mechanical coupling, allowing the counterweight to move in the opposite direction to the cradle. For example, when the support arm pivots to the right, the counterweight within the base may move to the left. In some embodiments, the movable counterweight may be completely housed within the base (e.g., in both the retracted and fully extended positions), making the moving parts invisible. The advantage of this configuration is that, although the limited space for counterweight movement restricts the distance of movement, there are no pinch points that could pose a risk of injury to the caregiver when the counterweight moves. Furthermore, the counterweight will always be able to move throughout its range of motion without impact.

[0070] In some embodiments, the counterweight may extend beyond the shape or periphery of the base. The advantage of this configuration is that, despite the risks of pinch points and objects outside the system obstructing the counterweight's movement, the counterweight can have a greater range of motion and its smaller weight can effectively balance the system compared to a system where the counterweight is contained within the base throughout its entire range of motion.

[0071] In some embodiments, a rack and pinion system may be included in the system to move the counterweight in a direction opposite to the movement of the support arm. In some embodiments, gear teeth may be disposed on the support column. The gear teeth may engage with a fixed rotating gear (which is also a pinion). The fixed rotating gear may engage with a rack rigidly connected to the counterweight. In some embodiments, when the support column rotates, the fixed rotating gear may rotate in the opposite manner, causing the counterweight to move linearly in a direction opposite to the support arm.

[0072] In some embodiments, a series of linkage arms can be used to move the counterweight. One linkage arm can be fixedly (e.g., rigidly) attached to a support column. When the support column rotates, the rigidly attached linkage arm can move (e.g., be pulled) in the same direction. A pivot rod can be connected to the linkage arm at one end, fixedly (e.g., rigidly) attached to the base at a central pivot point, and coupled to the counterweight at a second end, so that the cradle and the counterweight, which are connected to the support column via the support rod, produce opposite movements. In some embodiments, the system may include a belt and pulley system to produce the same relative movement.

[0073] In some embodiments, the movable counterweight may include a suction / grip system that includes a suction mechanism (e.g., a suction cup) or other gripping mechanism that can provide gripping force on the floor. For example, such as Figure 14 As shown, the counterweight may include a floor anchoring mechanism configured to anchor at least a portion of the system to the floor. The floor anchoring mechanism may include one or more suction mechanisms (e.g., suction cups) at its bottom, and when the counterweight is fully deployed, it can move downwards toward the floor and compress the suction cups into the floor. The activated suction mechanism can provide additional holding force beyond the weight of the counterweight and anchor the base more firmly while maintaining a small overall system or cart weight. The suction / grip system may include a mechanical release mechanism that allows the suction / grip to be broken by pulling up a portion of the area of ​​the suction mechanism providing the suction and breaking the seal before the counterweight is lifted and moved back to a centered or retracted position. In some embodiments, such a mechanical release mechanism may allow suction to be removed with very little force when needed and with a large force when not needed, thereby preventing accidental release of stable suction.

[0074] In some embodiments, the system may include multiple functions that can be locked and unlocked as needed by a user or clinician (e.g., through interaction with one or more release mechanisms). In some embodiments, the cradle pivot, support arm pivot, support column height adjustment, cradle extension, and / or casters on the base may all be locked or unlocked. In some embodiments, two different users (e.g., a clinician and a mother in a hospital bed) may interact with the locking features included in the system from two different positions (e.g., from opposite sides of the system, such as from the bed and from a position standing beside the bed opposite the system). In some embodiments, the base may be pushed beside the patient's (e.g., the mother's) hospital bed by a clinician and then locked in place relative to one or more locking features. The system may include lock release mechanisms on both sides of the support arm, such that a user in a first position relative to the system (e.g., positioned on a hospital bed) and a user in a second position relative to the system (e.g., a clinician standing beside the system opposite the first user) can access the lock release mechanisms so that the release mechanisms are accessible at all stages of use.

[0075] In some embodiments, a single release mechanism can control the release of all lockable functions (e.g., pivoting, height adjustment, cradle extension, and / or wheel movement). In some embodiments, multiple release mechanisms may be included, each release lever capable of independently releasing one or more (e.g., two) functions, independent of the other release levers. In some embodiments, a pair of release levers may be located on either side of the support arm, close to the cradle, allowing a patient sitting on a hospital bed to easily access at least one of the pair of release levers to lock and unlock the movement of the support column, support arm, and / or cradle without leaving the bed. This can allow the patient to pull the cradle containing the infant closer to them for diaper changes, feeding, and / or providing intermittent or continuous touches to soothe the infant. This can also include positioning the cradle directly above the mother when she is lying on the patient's bed. The patient can then return the infant (e.g., in the cradle) to a position beside the patient's bed without assistance and has free time to leave the bed, for example, to go to the bathroom. By including a pair of interconnected release levers, located on either side of the support arm, both the mother and the clinician can access the release lever associated with the same lockable function.

[0076] In some embodiments, the pivotable support arm may also include a delivery handle or lever for a clinician or user to push the system on the floor. The distal end of the support arm may also have a handle or lever to allow easy movement of the support arm without touching the cradle.

[0077] In some embodiments, the system may include a different release mechanism that can control the release of only a subset of functions. For example, a pair of two release mechanisms, located on either side of the support arm, can control the locking and unlocking of the support arm pivoting and / or the column height. In some embodiments, a second release handle can control the release of the support column height adjustment. In some embodiments, the wheel lock and the cradle pivot can be locked and unlocked independently. In some embodiments, other combinations of functions can be mapped to two or more release handles.

[0078] Including a pair or two handles that serve the same purpose but can be accessed by different people in different positions relative to the system provides increased flexibility. For example, including two different but interconnected pivot release handles can allow a clinician or a mother to control pivot release. In some embodiments, the two handles may be arranged on opposite sides of the support arm. In some embodiments, one set of handles may be located on the support arm, and a second set of handles may be located near the transport handle. In some embodiments, it is advantageous that each movable mechanism is controlled by a single release mechanism. For example, in some embodiments, one release mechanism can control the movement of the support arm pivot, and another separate release mechanism can control the movement of the cradle pivot.

[0079] In some embodiments, when transporting the cradle system from room to room or within a room, the system can be positioned in a "transportation position" (also referred to as a "transportation configuration"). In the transport position, the support arms can be in a fully retracted position. For example, the support arms can be aligned with the long axis of the base. The support column can be raised or lowered to achieve a desired height for transport. For example, the support column can be raised or lowered such that the system's handles (e.g., trolley handles) (e.g., for pushing or pulling the entire system) are approximately 40 inches above the floor, or between approximately 30 inches and approximately 50 inches. The cradle height can be as low as approximately 20 inches to approximately 25 inches from the ground (e.g., when a mother is in a hospital bed at the lowest setting), and the cradle height can be significantly increased if the patient's (e.g., the mother's) bed is raised. Once in the transport position, the user can unlock the wheels on the base and begin moving the system by pushing the transport handle (e.g., located at the distal end of the support arm).

[0080] In some embodiments, the system may include an interlocking mechanism to prevent the rollers from unlocking unless the system is in the transport position. In some embodiments, the system may not include an interlocking mechanism, and the wheel release mechanism may be switched to an unlocked configuration regardless of the position of the cradle, support arm, and / or support column.

[0081] In some embodiments, the system includes a stop or pin that indicates to the user whether the device is in transport mode. For example, the cradle may include a pivot locking pin that is positioned in a pivot locking receiver hole when the cradle is properly aligned with the transport arm for transport. Figure 15 It is a schematic perspective view of the cradle pivoting relative to the support arm of the cradle support system according to an embodiment, including a cradle pivot locking pin and a cradle pivot locking receiving hole.

[0082] In some embodiments, the system includes a pivot release mechanism comprising a pair of pivot release handles located on either side of the support arm. Each of the pair of pivot release handles may be interconnected via a mechanical coupling to one or more pivot points on the support arm. At least one pivot point may be arranged between the support column and the support arm. Figures 9-11 As shown, in some embodiments, the system may include a release handle connected to a locking strap via a series of coupling devices, including an overcenter mechanism. The locking strap may wrap around a circular pivot. When the coupling device moves to the locked position, the system can move through the overcenter configuration and tightly close the locking strap around the pivot. Therefore, a large force is applied from the locking strap to the pivot. The resulting high frictional force prevents movement of the pivot when an external load is applied by a physician or patient while maintaining a series of positions. In some embodiments, a series of mechanical coupling devices may connect two release handles, located on either side of the support arm, to two pivot release mechanisms, namely the cradle pivot and the support arm pivot.

[0083] In some embodiments, the pivot release device (also referred to as the pivot release handle) can be lifted by the patient or physician, causing the release coupling to move toward the pivot release device. This lateral movement of the release coupling causes the locking coupling to be pulled, resulting in the distal end of the locking coupling also translating toward the release device and away from the pivot point at the center of the locking plate. As the locking coupling moves laterally toward the release device, the locking plate is able to rotate in a manner that pushes the locking band toward the pivot, thereby releasing the pressure between the pivot and the locking band. This movement allows the pivot to rotate freely. When the pivot release device is pressed back to the starting position, all movements are reversed, and the locking band applies a large clamping force to the pivot. This results in high friction on the pivot and stops the pivot from rotating.

[0084] In some embodiments, the system can use a gear-type pivot and a key mechanism with engaging gear teeth instead of a locking band. The advantage of this mechanism is that the pivot interferes with the locking mechanism and only rotates in the event of a mechanical failure in the locking mechanism. However, in some embodiments, the pivot can only be locked in discrete positions, and overcoming the torque limitation of the mechanism can cause permanent damage to the mechanism. In some embodiments, two different pivots can be selectively controlled by a set of pivot release devices.

[0085] like Figure 9 and Figure 10As shown, in some embodiments, a pair of release devices can control the movement of the support arm pivot and the extension of the cradle and counterweight. Two locking plates can be connected by a pair of locking plate interconnecting couplings, such that the two locking plates move simultaneously in the same manner, and each locking band locks and unlocks simultaneously. One locking band can wrap around the support arm pivot, and a second locking band can wrap around the counterweight brake drum. The counterweight brake drum can be connected at one end to a counterweight pinion and at the second end to a cradle pinion via a gear shaft. When the support arm extends, the gear shaft can rotate, causing two gears to rotate, each interacting with the counterweight rack and the cradle rack, respectively. In some embodiments, a 2:1 gear ratio allows the cradle to extend a distance twice the counterweight extension distance. When the band brake is closed on the brake drum, rotation of the gear shaft is prevented, and any extension or retraction of the support arm and counterweight can be stopped.

[0086] In some embodiments, the system may include an electrical switch and actuator that provide locking force. For example, the switch and linear actuator may provide motion for locking and unlocking a center band brake. In some embodiments, an electric motor may mesh with a series of gears or teeth to provide rotational motion. In some embodiments, the system may include a mechanism comprising a solenoid that is in place when de-energized to provide mechanical locking, and that retracts when the lock is energized, allowing free movement of a rotational pivot.

[0087] In some embodiments, the system's wheels are designed to roll freely during transport. The wheels can roll and steer, allowing the stroller to be easily positioned in any orientation and direction. In some embodiments, all four wheels can steer freely. In some embodiments, two wheels can steer, and the other two wheels can only roll. In some embodiments, the wheels may include locking mechanisms or be coupled to locking mechanisms for bedside use. For example, locking wheels are desirable when adjusting the position of a cradle or putting an infant to sleep in it. In some embodiments, the system may include one or more wheel locking mechanisms, each of which may include a wheel and a foot pedal, the foot pedal locking all wheel movement in one position and allowing free movement in a second position. A user (e.g., a clinician) can independently lock one or more wheel locks. In some embodiments, one, some, or all wheels may include corresponding wheel locks or be associated with corresponding wheel locks, such that one, some, or all wheels can be locked.

[0088] In some embodiments, the release mechanism may be located on one side of the support arm and may also control the wheel locking mechanism. In some embodiments, a mechanical cable may be connected from the release mechanism to each of the four wheels. In some embodiments, the system may include an electronic brake release device such that engagement with the release mechanism generates an electrical signal to activate a clamp, over-center mechanism, solenoid, and / or similar mechanism to lock and unlock the wheel.

[0089] In some embodiments, the wheel release device may be located near the transport handle, so that only users (e.g., clinicians) within reach of the transport handle can access the wheel release device.

[0090] In some embodiments, the height of the support column needs to be adjusted to position the cradle at an ideal height above the bed. An adjustable height support column may include two parts: an upper part and a lower part. The lower part may be rigidly connected to a base. The upper part may be connected to a support arm via a pivot. The upper and lower parts of the support column may be coupled (e.g., connected) to each other via a linear bearing or bushing that allows the upper part to move up and down relative to the lower part. The cradle, support arm, upper part, and / or other movable mechanisms relative to the lower part can be quite heavy, thus requiring assistance from clinicians or users to lift the cradle. Additionally, users such as patients (e.g., mothers) may be limited by recent abdominal surgery and / or have limited strength when raising and lowering the cradle. In some embodiments, the system may include a height adjustment mechanism comprising a spring arranged to provide an upward spring force substantially equal to the weight of the vertically movable portion of the system relative to the lower part. In some embodiments, a damping mechanism may also be included in this mechanism to produce smooth movement. In some embodiments, a spring system may be included that provides a constant force throughout the entire range of motion of the upper part relative to the lower part, allowing the cradle to have the same range of travel as a typical hospital bed. In some embodiments, the system may include constant force springs. In some embodiments, the height adjustment mechanism may include a series of constant force springs arranged (e.g., held in place) around a central axis (e.g., arranged radially around the central axis and having longitudinally extending axes parallel to each other). In some embodiments, one end of the constant force spring may be held in place on a reel attachment bracket that is fixedly (e.g., rigidly) connected to the lower part of a support column. A second end of the constant force spring may be connected to a spring attachment plate that is fixedly (e.g., rigidly) connected to the upper part of the support column. In some embodiments, the reel attachment plate may be positioned above the spring attachment plate such that the constant force spring always provides an upward force on the upper support column, which is approximately equal to the weight of the structure supported by and including the upper support column. In some embodiments, an optional damper may be included (e.g., placed) within the structure (e.g., within the upper and / or lower support columns) to maintain smooth movement and avoid unwanted oscillations during use. Although a constant force spring has been described, in some embodiments, other springs, including helical springs, torsion springs, etc., may be alternatively or additionally included. In some embodiments, a compressed gas cylinder may be included to provide the spring force instead of a metal spring. In some embodiments, a compressed gas cylinder may be used additionally or alternatively to provide a locking force to the height adjustment mechanism. Figure 12 and Figure 13As shown, in some embodiments, the height adjustment mechanism may include a height adjustment release device connected via a cable to a mechanism for locking and unlocking a gas cylinder (also known as a gas spring cylinder). When the gas cylinder is closed, it prevents vertical movement of the component. When the height adjustment release device is pulled, the attached cable is also pulled, causing the gas stored in the gas cylinder to expand or contract. Figure 16 This is a schematic cross-sectional view of the gas cylinder of the cradle support system according to an embodiment.

[0091] In some embodiments, an electric mechanism may be used to change the height, including a motor with a rack and pinion system, a linear actuator, and / or various other electric mechanisms.

[0092] In some embodiments, the release mechanism can provide clamping force during normal use, preventing any unintended changes in the support column height. When the release lever is actuated, the clamping force can be released, and the user can then adjust the cradle height as needed. The height release mechanism can be a single handle that controls only the height, or it can include a single handle that controls only the height, or it can be connected to one or more handles that control one or more functions.

[0093] In some embodiments, the system may include an electrically operated linear actuator (e.g., within or coupled to a second portion of the support column). For example, a linear actuator may replace springs and dampers. In response to a user pressing a button to raise the cradle, the linear actuator may be energized and lengthened, thereby pushing the second portion away from the first portion and raising the cradle. When the user presses a different button to lower the cradle, the linear actuator may be energized and lengthened, thereby translating the second portion toward the first portion and lowering the cradle. When no button is pressed, the system may lock in place and maintain the existing height of the support column and cradle.

[0094] In some embodiments, the system described herein may be configured to support a tray, table, or platform, rather than a cradle. For example, as Figure 22 As shown, system 2200 can be configured to support tray 2218. System 2200 may be structurally and / or functionally similar to other systems described herein, including cradle support systems, but adapted for supporting a tray. For example, system 2200 may include a base 2202, wheels 2214, support columns 2206, support arms 2204, and counterweight 2210. These components may be structurally and / or functionally similar to other similar components, including, for example, base 1702, wheels 1714, support columns 1706, support arms 1704, and counterweight 1710, and / or the base, support columns, support arms, and counterweight of system 100. Therefore, certain details of these components are not described further with respect to system 2200.

[0095] The tray 2218 may include a flat surface and is configured to support an infant and / or one or more objects, such as above a patient bed. In some embodiments, the tray 2218 may include raised edges, for example, to help prevent objects from rolling off the tray. In some embodiments, the tray 2218 may be slidably coupled to a support arm 2204, for example, such that the tray 2218 can extend relative to the support arm 2204. Alternatively or additionally, the support arm 2204 may be telescopic, such that extending the length of the support arm 2204 can extend the tray 2218 away from the support post 2206. In some embodiments, the tray 2218 may be configured to extend up to about 2 feet from its retracted or stowed position, or between about 1 foot and about 3 feet (inclusive of all subranges and values ​​in between). In some embodiments, the tray 2218 may be pivotable relative to the support arm 2204, for example, via a pivotable connection between the tray and the support arm 2204. For example, the tray 2218 may be configured to pivot up to about 90 degrees to the left or right in each direction. The tray may include one or more handles 2219a, 2219b, which may be configured for a user to grip to change the position, orientation, or configuration of the tray. For example, a user may grip one or more of the handles 2219a, 2219b to extend or retract the tray along the length of the support arm 2204 and / or to rotate or pivot the tray relative to the base 2202. The support arm 2204 may also include one or more handles 2205, which may be used to move the system 2200 along the floor. As described with respect to the system above, the system 2200 may include one or more locking mechanisms for locking the wheels 2214, the height of the support column 2206, the extension and / or retraction of the tray 2218, and / or the pivoting of the tray 2218.

[0096] By including counterweight 2210, system 2200 can be configured to maintain stability when the tray is deployed (e.g., extended and / or pivoted relative to its folded configuration), similar to the cradle support system described herein. Furthermore, although Figure 22 Not shown, but it is understood that system 2200 may include any number of counterweights or stability features, including, for example, floor anchoring mechanisms and / or movable counterweights.

[0097] This article also discloses the design of the cradle support system. Figures 23-42 Various views of the design of the cradle 2300 and its components are shown, as detailed below. Figures 23-42 As shown, a cradle or baby tub may include a front wall, a rear wall, and side walls. The front wall may include a height reduction section, for example, to allow the mother or other caregiver easier access to the baby placed in the cradle. In some embodiments, there may be two height reduction sections, for example, one for each arm of the mother or caregiver. In some embodiments, there may be a single, continuous height reduction section. Figure 31 As shown, the insert 2302 can be positioned in the cradle at multiple locations and configured to conform to the contours of the cradle's interior. In the first position, as... Figure 31 As shown, the insert 2302 can be positioned along the front wall, and thus within the area of ​​the height reduction section. This positioning allows the insert to block or cover the lower height section, for example, during extended periods when the infant may remain in the crib (e.g., while the infant is sleeping and / or being transported). This helps protect the infant and / or further ensures the infant is contained within the crib. In other words, when in the first position, the insert overlaps with the height reduction section and the front wall, thus providing a wall of approximately a single height to prevent the infant from rolling over or otherwise falling across the sides of the crib. In the second position, as... Figure 33 As shown, the insert 2302 can be positioned along the rear wall, for example, to be stored when not used to block the lower height portion of the front wall.

Where the method described above specifies that certain events occur in a certain order, the order of certain events can be modified. Furthermore, when possible, certain events can be executed simultaneously, and also sequentially as described above.

[0120] Where the accompanying drawings and / or embodiments described above indicate that certain components are arranged in certain orientations or positions, the arrangement of components can be modified. Although embodiments have been specifically shown and described, it should be understood that various changes in form and detail may be made. Any part of the apparatus and / or method described herein can be combined in any combination, except for mutually exclusive combinations. For example, different types of counterweights (e.g., fixed, movable, coupled to a support arm, or coupled to a base), floor anchoring mechanisms, support columns, etc., as shown in the various embodiments, can be combined in a single cradle support system. The embodiments described herein may include various combinations and / or sub-combinations of the functions, components, and / or features of the various different embodiments described.

[0121] As used herein, the terms “about,” “approximately,” and / or “roughly” are intended, when used with respect to stated values ​​and / or geometries or relationships, to express that the defined value or characteristic is nominally the value or characteristic described in the statement. In some instances, the terms “about,” “approximately,” and / or “roughly” may mean and / or substantially take into account a stated value or characteristic within a desired tolerance range (e.g., plus or minus 10% of the stated value or characteristic). For example, a value of about 0.01 may include 0.009 and 0.011, a value of about 0.5 may include 0.45 and 0.55, a value of about 10 may include 9 to 11, and a value of about 1000 may include 900 to 1100. Similarly, when a first surface and a second surface are nominally parallel, the first surface may be described as substantially parallel to the second surface. While stated values, structures, and / or relationships may be desirable, it should be understood that some deviations may occur due to, for example, manufacturing tolerances or other practical considerations (e.g., pressure or force applied through a part of a device, conduit, lumen, etc.). Therefore, the terms “about,” “approximately,” and / or “roughly” may be used in this document to take such tolerances and / or considerations into account.
