[0043] In some embodiments, systems and methods described herein are directed toward a positionable over-bed bassinet (e.g., infant tub) or tray with balanced support and / or user-controlled release mechanisms.

[0044] In some embodiments, a system includes a base, a support column, a pivotable support arm, a bassinet or tray, a counterweight (also referred to as a counterweight system) and at least one release mechanism.

[0045] In some embodiments, the system can be the same as or similar in structure and / or function to any of the systems described in, for example, U.S. Pat. No. 11,116,330, issued Sep. 14, 2021, entitled “Bassinet” (hereinafter “the '330 patent”), which is incorporated by reference herein in its entirety. In some embodiments, the systems and / or method steps described herein can be used in conjunction with and / or incorporated into any systems, apparatus, or methods that are the same as or similar to those described in the '330 patent.

[0046] The base includes a horizonal surface and includes or is coupled to wheels for free movement across a floor. The base is rigidly connected to the support column. In some embodiments, the wheels of the base can be lockable. In some embodiments, the wheels provide rolling and castoring motion, allowing for free movement of the base across the floor. In some embodiments, the base can include a storage system, which can include shelves for supplies, located in otherwise empty space under the bassinet.

[0047] The support column is a vertical structure which connects to the base at the bottom of the support column and to the pivotable support arm at the top of the support column. The support column can include an adjustable height feature, which allows the length of the support column to change. The support column can include two pieces, a first or lower piece (also referred to as a first or lower section) and a second or upper piece (also referred to as a second or upper section). The lower section can be attached to the base. In some embodiments, the upper piece can be connected to the lower section by a guide rail, so the upper section may move up or down (e.g., along the guide rail) as desired by the 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 can also contain a damper 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 can be controlled by a linear actuator or other powered mechanism. In some embodiments, the top of the support column can be connected to the support arm via a pivot.

[0048] The pivotable support arm is a horizontal structure which connects the support column to the bassinet or tray. The pivotable support arm can include at least one pivot which is located directly above the support column (e.g., the support arm is configured to pivot relative to the base about a pivot axis extending along a length of the support column), and, in some embodiments, the pivotable support arm can include a second pivot located underneath the bassinet or tray (e.g., at least a portion of the support arm is configured to pivot relative to the base about a second pivot axis that is separate from the first pivot axis, such as a pivot axis that extend through a center or central region of the bassinet or tray), as shown in FIG. 15. The second pivot can enable the bassinet or tray to independently pivot relative to the base. The pivotable support arm can include one or more release handles which actuate locking mechanisms. In some embodiments, a single release mechanism can control the release of multiple functions (e.g., pivoting, height adjustment and wheel motion). In some embodiments, a multitude of release mechanisms can be used, with each release lever responsible for releasing one or two functions independently of other release handles. In some embodiments, the pivotable support arm can also contain transport handles for a clinician or user to push the system across the floor.

[0049] In some embodiments, the pivotable support arm also includes (e.g., contains) or is coupled to a counterweight system. In some embodiments, the pivotable support arm can also have an extension capability, so that it can extend farther over the bed during use and can be retracted back into a more compact position when needed. The pivotable support arm can also include a handle on the distal end of the support arm, which facilities a mother easily positioning the bassinet or tray and support arm relative to a bed while remaining disposed in the bed.

[0050] The bassinet is a tub-shaped structure which is able to safely contain a newborn infant. The tub can be removably attached to the support arm. The tray can be a flat structure, which can be configured to provide a flat surface for supporting a newborn infant or other objects. In some embodiments, the tray can include a raised edge or outer border. The tray can be removably attached to the support arm. The bassinet and the tray can be examples of holding structures, e.g., a structure configured to hold one or more objects.

[0051] Systems, devices, and methods described herein can include a counterweight system that is configured to bias weight away from a bassinet or tray, such that the bassinet or tray can be extended a further distance away from a support column supporting the bassinet or tray without causing the system to lose stability. In some embodiments, the counterweight system can include a fixed counterweight which is coupled (e.g., fixedly or rigidly attached) to the support arm of the system, as depicted in FIGS. 1A-1E.

[0052] As depicted in FIGS. 1A-1E, a system 100 for supporting a bassinet can include a base, a support column, a support arm, a counterweight system, and a bassinet. The system depicted in FIGS. 1A-1E can include components that are structurally and / or functionally similar to components of other systems for supporting bassinets described herein and / or described in the '330 patent. The base can be coupled to a set of wheels or other transport elements (e.g., tracks, rollers, etc.), which can be configured to allow the system to move across a floor or other flat surface. The support column can extend upward or vertically from the base to a support arm. The support arm can be pivotable relative to the support column and / or base. In some embodiments, the support arm can include a pivot which is located above the support column, and, in some embodiments, the support arm can include a first pivot which is located above the support column and a second pivot located underneath the bassinet. In some embodiments, the support arm can also have an extension capability, so that it can extend farther over the bed during use and can be retracted back into a more compact position when needed. The support arm can include one or more locking mechanisms for locking one or more pivots of the support arm and / or locking an extension or retraction of the support arm.

[0053] The bassinet can be supported by the support arm. As described above, the bassinet can be pivotably coupled to the support arm. FIGS. 1A and 1B depict the support arm in a first configuration, where the support arm is aligned with the base (e.g., the support arm and the base extend parallel to one another) and / or the bassinet is centered with respect to the base. FIG. 1A depicts a top view of the system in the first configuration, and FIG. 1B depicts a side view of the system in the first configuration. FIGS. 1C and 1D depict the support arm in a second configuration, where the support arm has been pivoted relative to the base. In this pivoted configuration, the bassinet may be disposed to one side of the base. FIG. 1C depicts a top view of the system in the second configuration, and FIG. 1D depicts a side view of the system in the second configuration. The bassinet can be coupled to the support arm at an end of the support art that is opposite to the support column. In other words, the bassinet can be coupled to a portion of the support arm that is extends away from the support column. This location of the bassinet can enable the bassinet to be positioned over a bed of a patient (e.g., a hospital bed). However, because the bassinet is supported on an end of the support arm that is not directly over the support column and therefore overhangs the base, the weight of the bassinet can bias the center of gravity of the system toward the bassinet. Therefore, to counteract this bias, the system can include a counterweight located on an end opposite to the bassinet. In some embodiments, the support arm can also be configured to extend in length. For example, the support arm, when fully deployed, can increase in length compared to its undeployed or retracted configuration by up to about 2 feet, or between about 1 feet and about 3 feet (inclusive of all sub-ranges and values therebetween). In such embodiments, a counterweight can also be used to counteract the greater torque load owing to the greater length of the support arm and the position of the bassinet (e.g., further out from the support column),

[0054] As shown in FIGS. 1A-1E, the system includes a counterweight that is located on the opposite end of the support arm from the bassinet such that the bassinet is disposed on and / or coupled to a first end of the support arm and the counterweight is disposed on and / or coupled to a second end of the support arm. In some embodiments, the counterweight is located on a first section of the support arm and the bassinet is located on a second section of the support arm, with the first and second sections of the support arm configured to translate or move relative to one another. The first section can be coupled to the support arm, whereas the second section can be configured to translate relative to the first section, and therefore to extend or translate away from the support column. In some embodiments, the second section can be disposed on rails or guides, and can translate relative to the first section via the rails or guides. The second section can overhang the base and / or floor, thereby allowing the bassinet to be supported over a bed of a patient. In some embodiments, the counterweight can have a weight such that, when the bassinet is in a retracted or stowed position relative to the base (e.g., when the bassinet is disposed partially, mostly, or entirely above the base, or when the support arm does not extend beyond the sides of the base), a center of gravity of the system can be closer to a center of the base, e.g., reducing or minimizing tipping or loss of stability. In some embodiments, the counterweight can have a weight such that, when the bassinet is in a retracted or stowed position relative to the base, the center of gravity of the system can be biased towards the counterweight, e.g., can be on an edge of the support column closest to the counterweight, can be slightly outside the support column towards the side with the counterweight, or generally closer to the side of the support arm with the counterweight than the opposite side with the bassinet.

[0055] Once the bassinet is fully extended or deployed relative to the base (e.g., such that the bassinet extends away from the base and is not disposed above the base or has a smaller portion disposed above the base than when in the retracted or stowed position), the center of gravity of the system can shift further away from the center of the base. For example, in some embodiments, the center of gravity can shift to a location on the bassinet side of the support column, outside the profile or perimeter of the support column towards the bassinet, or generally closer to the side of the support arm including the bassinet than the side including the counterweight. FIGS. 1C and 1D depict a first deployed configuration of the bassinet, whereby the support arm has been pivoted relative to the base and therefore the center of gravity has shifted further away from the center of the base. FIG. 1E depicts a second deployed configuration of the bassinet, whereby the support arm has been extended in length and therefore the center of gravity has also shifted further away from the center of the base, e.g., in a direction toward the bassinet. In some embodiments, in all configurations (e.g., all positions of the bassinet relative to the base, such as the retracted or stowed position, a pivoted position, or the fully extended or deployed position), the center of gravity can remain inside an area defined by the four wheels located on the base (e.g., within an area or volume having a perimeter spaced from the four wheels) to maintain stability. The presence of the counterweight and biasing of the weight away from the bassinet, compared to a system without a counterweight, can allow for further extension of the bassinet over the mother's bed while minimizing or reducing the torque load that is seen in the support column, and can keep the center of gravity of the system further away from unstable potential locations or regimes that could result in tipping of the entire system.

[0056] In some embodiments, the counterweight can have a weight that offsets the torques, forces, or effort applied by the combined weight of the support arm, the bassinet, a baby disposed in the bassinet, and / or additional forces applied to the bassinet by patients or clinicians during interactions with the baby and / or the bassinet. In some embodiments, the counterweight can have a weight sufficient to offset the torques and forces resulting from the combined weight of the support arm, the bassinet, a baby disposed in the bassinet, and / or additional forces applied to the bassinet by patients or clinicians during interactions with the baby and / or the bassinet, while the support arm is fully deployed or extended (e.g., extended in length by up to about 2 feet). The weight of the counterweight can be set or selected based on factors including, for example, the weight of the bassinet, the location of the bassinet (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 such weight along its length), the location the support arm is coupled to the support column, the location of the counterweight, the weight of the base (and the distribution of such weight), the location of the wheels (e.g., where the base is supported on the floor), among other factors. In some embodiments, the counterweight can have a weight ranging between about 5 kg and about 30 kg (inclusive of values and subranges therebetween), to sufficiently offset torques and forces resulting from the combined weight of the support arm, the bassinet, a baby disposed in the bassinet, and / or additional forces applied to the bassinet by patients or clinicians during interactions with the baby and / or the bassinet. For example, assuming an average infant weight of between about 4 lbs and about 14 lbs (or about 1.8 kg and about 6.4 kg), and a maximum extension of the support arm in the fully deployed configuration of up to about 2 feet, the counterweight can have a weight of about 25 kgs or 55 lbs to counterbalance the torque and forces resulting from the combined weight of the support arm, the bassinet, and the infant disposed in the bassinet.

[0057] While a bassinet is shown with respect to FIGS. 1A-1E (and further figures and embodiments below), it can be appreciated that such systems are not limited to a bassinet and can also be used for a tray, such as, for example, the tray shown in FIG. 22.

[0058] FIGS. 17-21 depict views of an example bassinet support system 1700 in various configurations, according to embodiments. FIG. 17 depicts a top view of the bassinet support system 1700 in a centered configuration. FIG. 18 depicts a top view of the bassinet support system 1700 in a first deployed configuration. FIG. 19 depicts a side view of the bassinet support system 1700 in the centered configuration. FIG. 20 depicts a side view of the bassinet support system 1700 in the first deployed configuration. FIG. 21 depicts a top view of the bassinet support system 1700 in a second deployed configuration. The bassinet support system 1700 can be structurally and / or functionally similar to other bassinet support systems described herein, including, for example, the bassinet support system 100 depicted in FIGS. 1A-1E.

[0059] As shown, the bassinet support system 1700 can include a base 1702, a support arm 1704, a support column 1706, a release handle 1712, a counterweight 1710, and a bassinet 1708. Similar to the base of the system 100, the base 1702 includes a horizonal surface and includes or is coupled to wheels 1714 for free movement across a floor. The base 1702 is coupled to the support arm 1706. The wheels 1714 can provide rolling and castoring motion, allowing for free movement of the base across the floor. The support column 1706 can extend vertically from the base 1702 to a support arm 1704. The support column 1706 can be configured to support the support arm 1704 at a set height relative to the base 1702. The support column 1706 can be configured to adjust in height, e.g., enabling a height of the support arm 1704 to be adjusted. In some embodiments, the support column can include one or more sections that can be adjusted relative to one another, e.g., by releasing a locking mechanism, to adjust the height of the support column. The adjustment of the height of the support column can enable the system 1700 to be adapted for different heights of beds, e.g., to enable the bassinet 1708 to be positioned over beds of different heights.

[0060] As shown in FIGS. 19 and 20, the support arm 1702 can include a first end that overhangs the base 1702 and / or floor and a second end that sit above the support column 1706. The support arm 1704 can be configured to pivot relative to the base 1702 via a pivotable connection to the support column 1706. For example, as shown in FIGS. 18 and 20, the support arm 1704 can pivot relative to the base 1702 to a right side. In some embodiments, the support arm 1704 can similarly pivot relative to the base 1702 to a left side. In some embodiments, the support arm 1704 can pivot relative to the base 1702 in all degrees (e.g., 360 degrees). Alternatively, in some embodiments, the support arm 1704 can be limited to pivot to the right side and / or to the left side by a up to about 90 degrees, or between about 60 and about 120 degrees (inclusive of all sub-ranges and values therebetween), in each direction. The bassinet 1708 can be disposed on the support arm 1704. In some embodiments, the bassinet 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 bassinet 1708 can be configured to enable the bassinet to be extended relative to (e.g., translated a distance from or moved away from) the support column to a deployed configuration, as shown in FIG. 21. For example, the bassinet 1708 can be configured to be extended relative to the support column by up to about 2 feet, inclusive of all sub-ranges and values therebetween. In some embodiments, the support arm can have two sections, where one of the sections can extend out from or away from the support column. In some embodiments, the bassinet can be coupled to the support arm via one or more tracks, which allow the bassinet to be extended out from or translated away from the support column and / or support arm.

[0061] Similar to the bassinet support system 100, the bassinet support system 1700 can include a counterweight system including a counterweight 1710. The counterweight 1710 can be coupled to (e.g., fixedly attached to) an end of the support arm 1704 opposite the overhanging end of the support arm 1704. In some embodiments, the counterweight 1710 can have a weight such that, when the bassinet is in a retracted or stowed configuration relative to the base (e.g., when the bassinet is disposed partially, mostly, or entirely above the base, or when the support arm is aligned with the base), a center of gravity of the system can be substantially close to a center of the base, e.g., reducing or minimizing tipping or loss of stability. For example, as shown in FIG. 17, when the bassinet 1708 and support arm 1704 are aligned with the base, the center of gravity of the system can be substantially located at the center of the base. When the support arm 1704 and bassinet 1708 are deployed, e.g., pivoted away to the right or left, or when the support arm 1704 is extended, the center of gravity of the system may shift, e.g., due to the additional moment or torque applied by the weight of the bassinet (and infant disposed therein) and / or weight of the support arm relative to the support column. As such, to avoid tipping or loss of stability of the system, the counterweight 1710 can be set or selected to have a weight that sufficiently counterbalances the moment, torques, or forces applied by the combined weight of the bassinet, infant, and / or support arm.

[0062] FIGS. 18 and 20 depict a first deployed configuration of the bassinet, whereby the support arm has been pivoted relative to the base and therefore the center of gravity has shifted away from the center of the base 1702. FIG. 21 depicts a second deployed configuration of the bassinet, whereby the support arm has been extended in length and therefore the center of gravity has shifted further away from the center of the base, e.g., in a direction that the support arm 1704 has been extended. In some embodiments, in all configurations (e.g., all positions of the bassinet relative to the base, such as the retracted or stowed position, a pivoted position, or the fully extended or deployed position), the center of gravity can remain inside an area of stability of the system. In some embodiments, the area of stability of the system can be defined as an area within the four wheels of the base (e.g., within an area or volume having a perimeter spaced from the four wheels). The presence of the counterweight 1710 to counterbalance the weight of the bassinet and / or infant, compared to a system without a counterweight, can allow for further extension of the bassinet over the mother's bed while minimizing or reducing the torques or forces seen in the support column, and can keep the center of gravity of the system further away from unstable potential locations that can result in tipping of the system 1700.

[0063] In some embodiments, the counterweight can be coupled to (e.g., fixed to and / or contained within) the base. As shown in FIG. 2, in some embodiments, the counterweight can be placed on a side of the base (e.g., the left side of the base). When the bassinet is in the stowed or retracted position, the center of gravity of the system would also be to one side of center of the base and the system (also referred to as a cart) (e.g. the left side), but remain safely within an envelope or perimeter (e.g., a rectangular perimeter) having boundaries (e.g., edges and sides) defined by the wheels (e.g., four wheels) supporting the base and connecting the base to the floor, resulting in a stable system. In some embodiments, the system (e.g., the support arm and / or support column) can include physical rotation stops for mechanically limiting the rotational range of the support arm relative to the base such that the support arm can rotate only toward the opposite side of the cart than the counterweight is disposed (e.g., right). When the bassinet is fully deployed (e.g., fully extended and rotated 90 degrees to the right) (e.g., the maximum extension position of the bassinet away from the base for which counterbalancing may be needed for stability), the center of gravity can move to the right side of the base, but remain safely within the envelope or perimeter of support defined by the wheels of the base. Compared to embodiments including a counterweight included in or coupled to the support arm, more of the weight of the system including the counterweight in the base is disposed closer to the floor, and therefore the system including the counterweight in the base can have improved stability. The support column of the system including the counterweight in the base, however, can experience and need to withstand a larger moment from the extended bassinet compared to a support column of a system including a counterweight included in or coupled to the support arm. In some embodiments, as shown in FIG. 2, the counterweight can be disposed on only one side of the base (e.g., entirely on one side of a central axis of the base and opposite the direction the support arm projects from the base when the system is in a deployed configuration). In some embodiments, the counterweight can be disposed in or coupled to the base such that most of the counterweight is disposed on one side of the base (e.g., the majority of the counterweight is disposed on one side of the central axis of the base and opposite the direction the support arm projects from the base when the system is in a deployed configuration).

[0064] In some embodiments, as shown in FIGS. 3-7, the counterweight system can move in connection with the movement of the bassinet. In some embodiments, a movable counterweight is coupled (e.g., attached) to the support arm in a similar location as described above with respect to FIG. 1. In some embodiments, the counterweight and the bassinet (and the movement thereof) are mechanically linked so that movement of the bassinet causes associated simultaneous movement of the counterweight. For example, in some embodiments, extension of the bassinet away from the support column by the user causes the counterweight to extend away from the support column (e.g., in the opposite direction) simultaneously. In some embodiments, the bassinet, support arm, and counterweight are arranged such that when the counterweight is disposed closest to the support column (retracted), the bassinet is also closest to the support column (retracted), and, when the bassinet is extended away from the support column, the counterweight extends away from the support column (e.g., in the opposite direction). The mechanical linkage between the bassinet and the counterweight can be include a rack and pinion mechanism, gears attached to a link arm, a series of mechanical linkages, and / or a variety of other mechanical linkages.

[0065] By making the counterweight movable, a smaller counterweight can accomplish the same or a similar balancing effect as a fixed counterweight coupled to the support arm or the base (e.g., as shown and described with respect to FIGS. 1 and 2). This is owing to the greater moment or torque that can be generated by moving the counterweight to offset the torques and forces applied by the weight of the bassinet and / or baby. By reducing the weight of the counterweight, the overall weight of the system can be reduced, making movement of the system through hallways and within a room easier while maintain the same level of stability. In some configurations, the moveable counterweight has a weight between about 5 kg and about 30 kg, and / or can be configured to move between about 10 cm to about 30 cm when extending from a retracted to a deployed position. In some embodiments, the bassinet can be configured to move or extend a similar distance to the movement distance of the counterweight. In some embodiments, the counterweight can move a greater distance than the bassinet when each move between the retracted and deployed positions. In some embodiments, the counterweight can move a smaller distance than the bassinet when each move between the retracted and deployed positions. In some embodiments, the counterweight may have a spot (e.g., define a cavity) for additional storage of items.

[0066] In some embodiments, the bassinet can be connected to a rack gear, which interacts with a bassinet pinion gear. This bassinet pinion gear can be connected via a shaft to a counterweight pinion gear, which meshes with a counterweight rack gear. The size of the bassinet pinion gear and the counterweight rack gear can be varied to change the relative motion of the counterweight versus the bassinet. FIG. 6, for example, shows the system including a bassinet pinion gear that is two times larger than a counterweight pinion gear, so that the counterweight moves half the distance that the bassinet moves. In some embodiments, alternatively, the two pinion gears can have a 1:1 ratio and / or the counterweight can be geared to move a greater distance than the bassinet.

[0067] In some embodiments, as shown in FIG. 8, the moveable counterweight can be coupled to (e.g., located in) the base. For example, in some embodiments, the counterweight can have a retracted position disposed in the center of the base (e.g., aligned with a central axis of the base), and can be coupled to the bassinet via mechanical linkages such that the counterweight moves in an opposite direction of the bassinet. When the support arm pivots to the right, for example, the counterweight within the base can move to the left. In some embodiments, the movable counterweight can be fully contained within the base (e.g., in both the retracted position and the fully deployed position), such that no moving parts are visible. The advantage of this configuration is that, although the space for movement of the counterweight such that the movement distance may be limited, there are no pinch points which may risk injury to the caregiver when the counterweight moves. Additionally, the counterweight will always be able to move throughout the full range of motion without impingement.

[0068] In some embodiments, the counterweight can extend beyond the profile or outer perimeter of the base. The advantage of this configuration is that, although there is a risk of pinch points and a risk of objects external to the system blocking movement of the counterweight, the counterweight can have a greater range of motion and a smaller weight can effectively balance the system compared to a system in which the counterweight is container within the base throughout its entire range of motion.

[0069] In some embodiments, a rack and pinion system can be included in the system to move the counterweight in a direction opposite of the support arm's movement. In some embodiments, gear teeth can be disposed on the support column. The gear teeth can engage with a fixed rotation gear, which is also the pinion gear. The fixed rotation gear can engage with a rack gear which is rigidly connected to the counterweight. In some embodiments, when the support column rotates, the fixed rotation gear can rotate in an opposite manner such that the counterweight moves linearly in an opposite direction of the support arm.

[0070] In some embodiments, a series of link arms can be used to move the counterweight. One link arm can be fixedly (e.g., rigidly) attached to the support column. When the support column rotates, the rigidly attached link arm can move (e.g., be pulled) in the same direction. A pivot bar can be connected to the link arm on one end, fixedly (e.g., rigidly) attached to the base at a central pivot point and coupled to the counterweight at the second end to cause opposite motion of the bassinet coupled to the support column via the support rod and the counterweight. In some embodiments, the system can include a belt and pulley system to create the same relative motion.

[0071] In some embodiments, the moveable counterweight can include a suction / traction system including a suction mechanism (e.g., a suction cup) or other gripping mechanism which can provide a gripping force on a floor. For example, as shown in FIG. 14, the counterweight can include a floor anchoring mechanism configured to anchor at least a portion of the system to the floor. The floor anchoring mechanism can include one or more suction mechanisms (e.g., suction cups) on the bottom, and, when the counterweight is fully deployed, the counterweight can move down towards the floor and compress the suction cup(s) into the floor. The activated suction mechanism(s) can provide additional holding force, beyond the weight of the counterweight, and keep the base more securely anchored, while maintaining a smaller overall system or cart weight. The suction / traction system can include a mechanical release such that, prior to the counterweight being raised and moved back to a center or retracted position, the suction / traction can be broken by pulling up on one section of the area of the suction mechanism providing suction and breaking the seal. In some embodiments, such a mechanical release can allow for a very low force to remove the suction when desired, and a high force to remove the suction when not desired, preventing accidental release of the stabilizing suction force.

[0072] In some embodiments, the system can include multiple functions which can be locked and unlocked as desired by a user or clinician (e.g., via interaction with one or more release mechanisms). In some embodiments, the bassinet pivot, the support arm pivot, the support column height adjustment, the extension of the bassinet, and / or the roller wheels on the base all can be locked or unlocked. In some embodiments, two different users can interact with the locking features included in the system (e.g., both a clinician and a mother in a hospital bed) from two different positions (e.g., from opposite sides of the system, such as from the bed and from a position standing near the bed opposite the system). In some embodiments, the base can be wheeled next to a patient's (e.g., mother's) hospital bed by a clinician, and then locked into place with respect to one or more of the locking features. The system can include lock releases on both sides of the support arm such that the lock releases can be reached by both a user in a first position relative to the system (e.g., disposed in a hospital bed) and by a user in a second position relative to the system (e.g., a clinician standing nearby opposite the system from the first user) to reach the releases throughout all phases of use.

[0073] In some embodiments, a single release mechanism can control the release of all lockable functions (e.g., pivoting, height adjustment, bassinet extension, and / or wheel motion). In some embodiments, a multitude of release mechanisms can be included, with each release lever being independent capable of releasing one or more (e.g., two) functions independently of other release handles. In some embodiments, a pair of release handles can be located on each side of the support arm, near the bassinet, such that a patient sitting in the hospital bed can easily reach at least one of the release handles of the pair to lock and unlock motion of the support column, support arm, and / or bassinet without leaving the bed. This can allow the patient to bring the bassinet with the baby close to them to change a diaper, feed the baby, and / or provide intermittent or continuous touch to comfort a baby. This can also include positioning the bassinet directly above the mother while she lies in the patient bed. The patient can then return the baby (e.g., within the bassinet) to a position next to the patient bed without assistance and freely leave the bed, to use the restroom for example. By the system including a pair of interconnected release handles, one on either side of the support arm, both the mother and the clinician can access a release handle associated with the same lockable function(s).

[0074] In some embodiments, the pivotable support arm can also contain transport handles, or grips, for a clinician or user to push the system across the floor. There may also be a handle, or grip, on the distal end of the support arm, to allow for easy movement of the support arm without touching the bassinet.

[0075] In some embodiments, the system can include a different release which can control the release of only a subset of functions. For example, a pair of two releases, one on either side of the support arm, can control the locking and unlocking of the pivoting of the support arm 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 locks and bassinet pivot can be locked and unlocked independently. In some embodiments, other combinations of functions can be mapped to two or more release handles.

[0076] Including a pair, or two different handles which have the same purpose, but can be reached by different people in different positions relative to the system provides added flexibility. For example, including two different, but interconnected, pivot release handles can allow either the clinician or the mother to control a pivot release. In some embodiments, the two handles can be disposed on opposite sides of the support arm. In some embodiments, one set of handles can be on the support arm, and a second set of handles can be located near the transport handles. In some embodiments, it may be beneficial to have each moveable mechanism controlled by a single release. For example, in some embodiments, one release mechanism can control the movement of the support arm pivot and a separate release mechanism can control the motion of the bassinet pivot.

[0077] In some embodiments, when transporting the bassinet system from room to room, or across a room, the system can be positioned in a “transport position” (also referred to as a “transport configuration”). In the transport position, the support arm can be positioned in the fully retracted position. For example, the support arm can be aligned with the long axis of the base. The support column can be raised or lowered to achieve a desirable height for transport. For example, the support column can be raised or lowered so that handles (e.g., cart handles) of the system (e.g., used for pushing or pulling the entire system) are about 40″ above the floor, or between about 30″ and about 50″. The bassinet height can be as low as about 20″ to about 25″ from the ground (e.g., when the mother is in a hospital bed at its lowest setting) and can be raised significantly if the patient's (e.g., mother's) bed is raised. Once in transport position, the user can unlock the roller wheels on the base and begin to move the system by pushing on the transport handles (e.g., located on the distal end of the support arm).

[0078] In some embodiments, the system can include an interlock to prevent unlocking of the roller wheels unless the system is in transport position. In some embodiments, the system can include no interlock, and the wheel release can be transitioned to an unlocked configuration regardless of the position of the bassinet, support arm, and / or support column.

[0079] In some embodiments, the system includes a detent or pin which indicates to the user that the device is in transport mode. For example, the bassinet can include a pivot lock pin, which can be disposed in a pivot lock receiving hole when the bassinet is properly aligned with the transport arm for transport. FIG. 15 is a schematic illustration of an isometric view of a bassinet pivoted relative to a support arm of a bassinet support system, including a bassinet pivot lock pin and a bassinet pivot lock receiving hole, according to an embodiment.

[0080] In some embodiments, the system includes a pivot release mechanism that includes a pair of pivot release handles which are located on both sides of the support arm. Each pivot release handle of the pair can be interconnected via mechanical linkages to one or multiple pivot points on the support arm. At least one pivot point can be disposed between the support column and the support arm. As shown in FIGS. 9-11, in some embodiments, the system can include a release handle, which is connected via a series of linkages, including an over center mechanism, to a locking band. The band can wrap around a circularly shaped pivot. When the linkages are moved to the locked position, the system can move through an over center configuration and close the band tightly around the pivot. A large amount of force is thereby applied from the band onto the pivot. The resulting high frictional forces prevent movement of the pivot when external loads are applied by a clinician or patient while maintaining a continuous range of positions. In some embodiments, the series of mechanical linkages can connect two release handles, one on either side of the support arm, to both pivot release mechanisms, the bassinet pivot and the support arm pivot.

[0081] In some embodiments, the pivot release (also referred to as pivot release handles) can be lifted by the patient or clinician, which causes a release linkage to move towards the pivot release. This lateral motion of the release linkage causes a pull on a locking linkage which causes the distal end of the locking linkage to also translate towards the release and away from a pivot point in the center of a locking plate. When the locking linkage moves laterally towards the release, the locking plate can rotate in a way that causes the locking band to be pushed towards the pivot shaft, releasing pressure between the pivot shaft and the locking band. This motion allows the pivot shaft to rotate freely. When the pivot release is depressed back to the starting position, all motions are reversed, and the locking band applies a large clamping force to the pivot shaft. This results in a high frictional force on the pivot shaft and stops rotation of the pivot shaft.

[0082] In some embodiments, rather than the locking band, the system can be replaced with a geared pivot shaft and a keyed mechanism which engages with the gear teeth. The advantage of this mechanism is that the pivot shaft has interference with the locking mechanism and will not rotate without mechanical failure of the locking mechanism. In some embodiments, however, the pivot shaft can only be locked in discrete positions and overcoming the torque limit of the mechanism is likely to create permanent damage to the mechanism. In some embodiments, two different pivots can optionally be controlled by a single set of pivot releases.

[0083] As shown in FIGS. 9 and 10, in some embodiments, the pair of releases can control the motion of both the support arm pivot and the extension of the bassinet and counterweight. The two locking plates can be connected by a pair of locking plate interconnect linkages, such that both locking plates move in the same manner at the same time, and the locking bands lock and unlock simultaneously. One locking band can wraps around the support arm pivot and the second locking band can wrap around the counterweight brake drum. The counterweight brake drum can be connected to the counterweight pinion gear on one end, and the bassinet pinion gear on a second end via a gear shaft. When the support arm is extended, the gear shaft can spin, spinning both gears, which interact with the counterweight rack gear and bassinet rack gear, respectively. In some embodiments, a 2:1 gear ratio allows the bassinet to extend twice as far as the counterweight extends. When the band brake is closed on the brake drum, rotation of the gear shaft can be prevented, and any extension or retraction of the support arm and counterweight can be stopped.

[0084] In some embodiments, the system can include electric switches and actuators which provide the locking force. For example, a switch and linear actuator can provide motion to lock and unlock an overcenter band brake. In some embodiments, electric motors can engage with a series of gears or teeth to provide rotational motion. In some embodiments, the system can include a mechanism that includes a solenoid which drops into place to provide a mechanical lock when unpowered, and, when the lock is powered, the solenoid can retract and allow free motion of the rotational pivot.

[0085] In some embodiments, the wheels of the system are designed to roll freely during transport. The wheels can both roll and castor, allowing easy positioning of the cart in any direction and orientation. In some embodiments, all four wheels can freely castor. In some embodiments, two of the wheels can castor and two of the wheels can only roll. In some embodiments, the wheels can include or be coupled to a locking mechanism for use at the bedside. For example, it may be desirable to have locked wheels when adjusting the position of the bassinet or letting a baby sleep in the bassinet. In some embodiments, the system can include one or more wheel lock mechanisms, which can each include a wheel and a foot pedal which locks out all wheel motion in one position and allows free motion in a second position. A user (e.g., the clinician) can independently lock one or multiple wheel locks. In some embodiments, one, some, or all of the wheels can include or be associated with a respective wheel lock such that one, some, or all of the wheels can be lockable.

[0086] In some embodiments, a release mechanism can be located on the side of the support arm and can also control the wheel lock mechanism. In some embodiment, a mechanical cable can be connected from the release mechanism to each of the four wheels. In some embodiments, an electronic brake release can be included in the system such that engagement with the release mechanism generates an electrical signal which activates a clamp, over center mechanism, solenoid, and / or similar mechanism which locks and unlocks the wheels.

[0087] In some embodiments, the wheel release can be located near the transport handle such that the wheel release only accessible to a user within reach of the transport handles (e.g., the clinician).

[0088] In some embodiments, the height of the support column may need to be adjusted to position the bassinet at the ideal height over a bed. The adjustable height support column can include two sections, the upper section and lower section. The lower section can be rigidly connected to the base. The upper section can be connected via a pivot to the support arm. The upper and lower sections of the support column can be coupled (e.g., connected) via a linear bearing or bushing, which allows the upper section to move up and down relative to the lower section. The weight of the bassinet, support arm, upper section, and / or other mechanism(s) movable relative to the lower section can be significant, and therefore it is desirable to assist the clinician or user in raising the bassinet. In addition, a user, such as a patient (e.g., a mother) may have limitations from recent abdominal surgery and / or may have limited strength when raising and lowering the bassinet. In some embodiments, the system can include a height adjustment mechanism including a spring disposed to provide an upward facing spring force nearly equivalent to the weight of the portion of the system vertically movable relative to the lower section. In some embodiments, to create a smooth motion, a damping mechanism can also be included in the mechanism. In some embodiments, a spring system can be included which provides a constant force over the full range of motion of the upper section relative to the lower section and allows the bassinet to have the same range of travel as a typical hospital bed. In some embodiments, the system can include a constant force spring. In some embodiments, the height adjustment mechanism can include a series of constant force springs disposed (e.g., held in place) around a central shaft (e.g., disposed radially around the central shaft and having parallel longitudinally extending axes). In some embodiments, one end of a constant force spring(s) can be held in place on a spool attachment bracket which is fixedly (e.g., rigidly) connected to the lower section of the support column. The second end of the constant force spring(s) can be connected to a spring attachment plate which is fixedly (e.g., rigidly) connected the upper section of the support column. In some embodiments, the spool attachment plate can be located above the spring attachment plate, so that the constant force spring(s) always provide 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 can be included (e.g., placed in) the structure (e.g., within the upper and / or lower support column) to keep the motion smooth and avoid unwanted oscillations during use. While a constant force spring is described, in some embodiments, other springs can alternatively or additionally be included, including coil springs, torsion springs, etc. In some embodiments, a compressed gas cylinder can be included to provide a spring force, rather than or in addition to a metal spring. In some embodiments, a compressed gas cylinder can be used additionally or alternatively to provide a locking force on the height adjustment mechanism. As shown in FIGS. 12 and 13, in some embodiments, a height adjustment mechanism can include a height adjustment release connected via a cable to a mechanism which locks and unlocks a gas cylinder (also referred to as a gas spring cylinder). When the gas cylinder is closed, it prevents vertical movement of the assembly. When the height adjustment release is pulled, the attached cable is also pulled, which releases the gas trapped within the gas cylinder to expand or contract. FIG. 16 is a schematic illustration of a cross-sectional view of a gas cylinder of a bassinet support system, according to an embodiment.

[0089] In some embodiments, electrically powered mechanisms may can be used to change the height, including motors with a rack and pinion system, linear actuators, and / or a variety of other powered mechanisms.

[0090] In some embodiments, a release mechanism can provide a clamping force during normal use, which prevents any inadvertent changes in height of the support column. When a release lever is actuated, the clamping force can be released, and the user can then adjust the height of the bassinet as needed. The height release mechanism can be or include a single handle which only controls the height, or can be connected to one or more handles, which can control one or more functions.

[0091] In some embodiments, the system can include a powered linear actuator (e.g., within or coupled to the second section of the support column). The linear actuator can, for example, replace the spring and the damper. In response to the user pressing a button to raise the bassinet, the linear actuator can be powered and increase in length, urging the second section away from the first section and raising the bassinet. When the user presses a different button to lower the bassinet, the linear actuator can be powered and decrease in length, translating the second section toward the first section and lowering the bassinet. When no buttons are being pressed, the system can lock in place and maintain the existing height of the support column and the bassinet.

[0092] In some embodiments, the systems described herein can be configured to support a tray, table, or platform, instead of a bassinet. For example, as shown in FIG. 22, a system 2200 can be configured to support a tray 2218. The system 2200 can be structurally and / or functionally similar to other systems described herein, including bassinet support systems, but be adapted for supporting a tray. For example, the system 2200 can include a base 2202, wheels 2214, a support column 2206, a support arm 2204, and a counterweight 2210. Such components can be structurally and / or functionally similar to other similar components, including, for example, base 1702, wheels 1714, support column 1706, support arm 1704, and counterweight 1710, and / or the base, support column, support arm, and counterweight of system 100. Therefore, certain details of these components are not described again with reference to system 2200.

[0093] The tray 2218 can include a flat surface, and be configured to support an infant and / or one or more objects, e.g., over a bed of a patient. In some embodiments, the tray 2218 can include a raised edge, e.g., to help prevent objects from rolling off the tray. In some embodiments, the tray 2218 can be slidably coupled to the support arm 2204, e.g., such that the tray 2218 can be extended relative to the support arm 2204. Alternatively or additionally, the support arm 2204 can be extendable such that the tray 2218 can be extended away from the support column 2206 by extending a length of the support arm 2204. In some embodiments, the tray 2218 can be configured to extend by up to about 2 feet, or between about 1 feet and about 3 feet (inclusive of all sub-ranges and values therebetween), from its retracted or stowed position. In some embodiments, the tray 2218 can be pivotable relative to the support arm 2204, e.g., via a pivotable connection between the tray and the support arm 2204. For example, the tray 2218 can be configured to pivot to a left side or a right side by up to about 90 degrees in each direction. The tray can include one or more handles 2219a, 2219b, which can be configured to be grasped by a user to change a position, orientation, or configuration of the tray. For example, a user may grasp one or more of the handles 2219a, 2219b to extend or retract the tray along a length of the support arm 2204 and / or to rotate or pivot the tray relative to the base 2202. The support arm 2204 can also include one or more handles 2205, which can be used to push the system 2200 along a floor. As described with systems above, the system 2200 can 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.

[0094] The system 2200, by including a counterweight 2210, can be configured to maintain stability while the tray is deployed (e.g., extended and / or pivoted relative to its stowed configuration), similar to bassinet support systems described herein. Moreover, while it is not depicted in FIG. 22, it can be appreciated that any number of counterweight or stability features can be included in system 2200, including, for example, floor anchoring mechanisms and / or movable counterweights.

[0095] Designs of bassinet support systems are also disclosed herein. FIGS. 23-42 depict various views of the design of a bassinet 2300 and / or its components, as detailed below. As shown in FIGS. 23-42, a bassinet or infant tub can include a front wall, a back wall, and side walls. The front wall can include reduced height sections, e.g., to allow for a mother or other caregiver to have easier access to an infant disposed within the bassinet. In some embodiments, there can be two reduced height sections, e.g., one for each arm of a mother or caregiver. In some embodiments, there can be one continuous reduced heigh section. As shown in FIG. 31, an insert 2302 can be positioned in the bassinet in multiple positions, and be configured to conform to the contours of the inside of the bassinet. In a first position, as shown in FIG. 31, the insert 2302 can be positioned along the front wall, and therefore be positioned in an area of the reduced height sections. Such positioning can enable the insert to block or cover the lower height sections, e.g., during longer periods of when an infant may be left inside the bassinet (e.g., during sleep and / or transport of the infant). This can help shield the infant and / or further ensure that the infant is contained within the bassinet. In other words, when in the first position, the insert overlaps the reduced height sections and the front wall, thereby providing a substantially wall of a single height to prevent infants from rolling or otherwise falling over the side of the bassinet. In a second position, as shown in FIG. 33, the insert 2302 can be positioned along the back wall, e.g., for storage when it is not being used to block the lower height sections of the front wall.

[0043] In some embodiments, systems and methods described herein are directed toward a positionable over-bed bassinet (e.g., infant tub) or tray with balanced support and / or user-controlled release mechanisms.

[0044] In some embodiments, a system includes a base, a support column, a pivotable support arm, a bassinet or tray, a counterweight (also referred to as a counterweight system) and at least one release mechanism.

[0045] In some embodiments, the system can be the same as or similar in structure and / or function to any of the systems described in, for example, U.S. Pat. No. 11,116,330, issued Sep. 14, 2021, entitled “Bassinet” (hereinafter “the '330 patent”), which is incorporated by reference herein in its entirety. In some embodiments, the systems and / or method steps described herein can be used in conjunction with and / or incorporated into any systems, apparatus, or methods that are the same as or similar to those described in the '330 patent.

[0046] The base includes a horizonal surface and includes or is coupled to wheels for free movement across a floor. The base is rigidly connected to the support column. In some embodiments, the wheels of the base can be lockable. In some embodiments, the wheels provide rolling and castoring motion, allowing for free movement of the base across the floor. In some embodiments, the base can include a storage system, which can include shelves for supplies, located in otherwise empty space under the bassinet.

[0047] The support column is a vertical structure which connects to the base at the bottom of the support column and to the pivotable support arm at the top of the support column. The support column can include an adjustable height feature, which allows the length of the support column to change. The support column can include two pieces, a first or lower piece (also referred to as a first or lower section) and a second or upper piece (also referred to as a second or upper section). The lower section can be attached to the base. In some embodiments, the upper piece can be connected to the lower section by a guide rail, so the upper section may move up or down (e.g., along the guide rail) as desired by the 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 can also contain a damper 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 can be controlled by a linear actuator or other powered mechanism. In some embodiments, the top of the support column can be connected to the support arm via a pivot.

[0048] The pivotable support arm is a horizontal structure which connects the support column to the bassinet or tray. The pivotable support arm can include at least one pivot which is located directly above the support column (e.g., the support arm is configured to pivot relative to the base about a pivot axis extending along a length of the support column), and, in some embodiments, the pivotable support arm can include a second pivot located underneath the bassinet or tray (e.g., at least a portion of the support arm is configured to pivot relative to the base about a second pivot axis that is separate from the first pivot axis, such as a pivot axis that extend through a center or central region of the bassinet or tray), as shown in FIG. 15. The second pivot can enable the bassinet or tray to independently pivot relative to the base. The pivotable support arm can include one or more release handles which actuate locking mechanisms. In some embodiments, a single release mechanism can control the release of multiple functions (e.g., pivoting, height adjustment and wheel motion). In some embodiments, a multitude of release mechanisms can be used, with each release lever responsible for releasing one or two functions independently of other release handles. In some embodiments, the pivotable support arm can also contain transport handles for a clinician or user to push the system across the floor.

[0049] In some embodiments, the pivotable support arm also includes (e.g., contains) or is coupled to a counterweight system. In some embodiments, the pivotable support arm can also have an extension capability, so that it can extend farther over the bed during use and can be retracted back into a more compact position when needed. The pivotable support arm can also include a handle on the distal end of the support arm, which facilities a mother easily positioning the bassinet or tray and support arm relative to a bed while remaining disposed in the bed.

[0050] The bassinet is a tub-shaped structure which is able to safely contain a newborn infant. The tub can be removably attached to the support arm. The tray can be a flat structure, which can be configured to provide a flat surface for supporting a newborn infant or other objects. In some embodiments, the tray can include a raised edge or outer border. The tray can be removably attached to the support arm. The bassinet and the tray can be examples of holding structures, e.g., a structure configured to hold one or more objects.

[0051] Systems, devices, and methods described herein can include a counterweight system that is configured to bias weight away from a bassinet or tray, such that the bassinet or tray can be extended a further distance away from a support column supporting the bassinet or tray without causing the system to lose stability. In some embodiments, the counterweight system can include a fixed counterweight which is coupled (e.g., fixedly or rigidly attached) to the support arm of the system, as depicted in FIGS. 1A-1E.

[0052] As depicted in FIGS. 1A-1E, a system 100 for supporting a bassinet can include a base, a support column, a support arm, a counterweight system, and a bassinet. The system depicted in FIGS. 1A-1E can include components that are structurally and / or functionally similar to components of other systems for supporting bassinets described herein and / or described in the '330 patent. The base can be coupled to a set of wheels or other transport elements (e.g., tracks, rollers, etc.), which can be configured to allow the system to move across a floor or other flat surface. The support column can extend upward or vertically from the base to a support arm. The support arm can be pivotable relative to the support column and / or base. In some embodiments, the support arm can include a pivot which is located above the support column, and, in some embodiments, the support arm can include a first pivot which is located above the support column and a second pivot located underneath the bassinet. In some embodiments, the support arm can also have an extension capability, so that it can extend farther over the bed during use and can be retracted back into a more compact position when needed. The support arm can include one or more locking mechanisms for locking one or more pivots of the support arm and / or locking an extension or retraction of the support arm.

[0053] The bassinet can be supported by the support arm. As described above, the bassinet can be pivotably coupled to the support arm. FIGS. 1A and 1B depict the support arm in a first configuration, where the support arm is aligned with the base (e.g., the support arm and the base extend parallel to one another) and / or the bassinet is centered with respect to the base. FIG. 1A depicts a top view of the system in the first configuration, and FIG. 1B depicts a side view of the system in the first configuration. FIGS. 1C and 1D depict the support arm in a second configuration, where the support arm has been pivoted relative to the base. In this pivoted configuration, the bassinet may be disposed to one side of the base. FIG. 1C depicts a top view of the system in the second configuration, and FIG. 1D depicts a side view of the system in the second configuration. The bassinet can be coupled to the support arm at an end of the support art that is opposite to the support column. In other words, the bassinet can be coupled to a portion of the support arm that is extends away from the support column. This location of the bassinet can enable the bassinet to be positioned over a bed of a patient (e.g., a hospital bed). However, because the bassinet is supported on an end of the support arm that is not directly over the support column and therefore overhangs the base, the weight of the bassinet can bias the center of gravity of the system toward the bassinet. Therefore, to counteract this bias, the system can include a counterweight located on an end opposite to the bassinet. In some embodiments, the support arm can also be configured to extend in length. For example, the support arm, when fully deployed, can increase in length compared to its undeployed or retracted configuration by up to about 2 feet, or between about 1 feet and about 3 feet (inclusive of all sub-ranges and values therebetween). In such embodiments, a counterweight can also be used to counteract the greater torque load owing to the greater length of the support arm and the position of the bassinet (e.g., further out from the support column),

[0054] As shown in FIGS. 1A-1E, the system includes a counterweight that is located on the opposite end of the support arm from the bassinet such that the bassinet is disposed on and / or coupled to a first end of the support arm and the counterweight is disposed on and / or coupled to a second end of the support arm. In some embodiments, the counterweight is located on a first section of the support arm and the bassinet is located on a second section of the support arm, with the first and second sections of the support arm configured to translate or move relative to one another. The first section can be coupled to the support arm, whereas the second section can be configured to translate relative to the first section, and therefore to extend or translate away from the support column. In some embodiments, the second section can be disposed on rails or guides, and can translate relative to the first section via the rails or guides. The second section can overhang the base and / or floor, thereby allowing the bassinet to be supported over a bed of a patient. In some embodiments, the counterweight can have a weight such that, when the bassinet is in a retracted or stowed position relative to the base (e.g., when the bassinet is disposed partially, mostly, or entirely above the base, or when the support arm does not extend beyond the sides of the base), a center of gravity of the system can be closer to a center of the base, e.g., reducing or minimizing tipping or loss of stability. In some embodiments, the counterweight can have a weight such that, when the bassinet is in a retracted or stowed position relative to the base, the center of gravity of the system can be biased towards the counterweight, e.g., can be on an edge of the support column closest to the counterweight, can be slightly outside the support column towards the side with the counterweight, or generally closer to the side of the support arm with the counterweight than the opposite side with the bassinet.

[0055] Once the bassinet is fully extended or deployed relative to the base (e.g., such that the bassinet extends away from the base and is not disposed above the base or has a smaller portion disposed above the base than when in the retracted or stowed position), the center of gravity of the system can shift further away from the center of the base. For example, in some embodiments, the center of gravity can shift to a location on the bassinet side of the support column, outside the profile or perimeter of the support column towards the bassinet, or generally closer to the side of the support arm including the bassinet than the side including the counterweight. FIGS. 1C and 1D depict a first deployed configuration of the bassinet, whereby the support arm has been pivoted relative to the base and therefore the center of gravity has shifted further away from the center of the base. FIG. 1E depicts a second deployed configuration of the bassinet, whereby the support arm has been extended in length and therefore the center of gravity has also shifted further away from the center of the base, e.g., in a direction toward the bassinet. In some embodiments, in all configurations (e.g., all positions of the bassinet relative to the base, such as the retracted or stowed position, a pivoted position, or the fully extended or deployed position), the center of gravity can remain inside an area defined by the four wheels located on the base (e.g., within an area or volume having a perimeter spaced from the four wheels) to maintain stability. The presence of the counterweight and biasing of the weight away from the bassinet, compared to a system without a counterweight, can allow for further extension of the bassinet over the mother's bed while minimizing or reducing the torque load that is seen in the support column, and can keep the center of gravity of the system further away from unstable potential locations or regimes that could result in tipping of the entire system.

[0056] In some embodiments, the counterweight can have a weight that offsets the torques, forces, or effort applied by the combined weight of the support arm, the bassinet, a baby disposed in the bassinet, and / or additional forces applied to the bassinet by patients or clinicians during interactions with the baby and / or the bassinet. In some embodiments, the counterweight can have a weight sufficient to offset the torques and forces resulting from the combined weight of the support arm, the bassinet, a baby disposed in the bassinet, and / or additional forces applied to the bassinet by patients or clinicians during interactions with the baby and / or the bassinet, while the support arm is fully deployed or extended (e.g., extended in length by up to about 2 feet). The weight of the counterweight can be set or selected based on factors including, for example, the weight of the bassinet, the location of the bassinet (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 such weight along its length), the location the support arm is coupled to the support column, the location of the counterweight, the weight of the base (and the distribution of such weight), the location of the wheels (e.g., where the base is supported on the floor), among other factors. In some embodiments, the counterweight can have a weight ranging between about 5 kg and about 30 kg (inclusive of values and subranges therebetween), to sufficiently offset torques and forces resulting from the combined weight of the support arm, the bassinet, a baby disposed in the bassinet, and / or additional forces applied to the bassinet by patients or clinicians during interactions with the baby and / or the bassinet. For example, assuming an average infant weight of between about 4 lbs and about 14 lbs (or about 1.8 kg and about 6.4 kg), and a maximum extension of the support arm in the fully deployed configuration of up to about 2 feet, the counterweight can have a weight of about 25 kgs or 55 lbs to counterbalance the torque and forces resulting from the combined weight of the support arm, the bassinet, and the infant disposed in the bassinet.

[0057] While a bassinet is shown with respect to FIGS. 1A-1E (and further figures and embodiments below), it can be appreciated that such systems are not limited to a bassinet and can also be used for a tray, such as, for example, the tray shown in FIG. 22.

[0058] FIGS. 17-21 depict views of an example bassinet support system 1700 in various configurations, according to embodiments. FIG. 17 depicts a top view of the bassinet support system 1700 in a centered configuration. FIG. 18 depicts a top view of the bassinet support system 1700 in a first deployed configuration. FIG. 19 depicts a side view of the bassinet support system 1700 in the centered configuration. FIG. 20 depicts a side view of the bassinet support system 1700 in the first deployed configuration. FIG. 21 depicts a top view of the bassinet support system 1700 in a second deployed configuration. The bassinet support system 1700 can be structurally and / or functionally similar to other bassinet support systems described herein, including, for example, the bassinet support system 100 depicted in FIGS. 1A-1E.

[0059] As shown, the bassinet support system 1700 can include a base 1702, a support arm 1704, a support column 1706, a release handle 1712, a counterweight 1710, and a bassinet 1708. Similar to the base of the system 100, the base 1702 includes a horizonal surface and includes or is coupled to wheels 1714 for free movement across a floor. The base 1702 is coupled to the support arm 1706. The wheels 1714 can provide rolling and castoring motion, allowing for free movement of the base across the floor. The support column 1706 can extend vertically from the base 1702 to a support arm 1704. The support column 1706 can be configured to support the support arm 1704 at a set height relative to the base 1702. The support column 1706 can be configured to adjust in height, e.g., enabling a height of the support arm 1704 to be adjusted. In some embodiments, the support column can include one or more sections that can be adjusted relative to one another, e.g., by releasing a locking mechanism, to adjust the height of the support column. The adjustment of the height of the support column can enable the system 1700 to be adapted for different heights of beds, e.g., to enable the bassinet 1708 to be positioned over beds of different heights.

[0060] As shown in FIGS. 19 and 20, the support arm 1702 can include a first end that overhangs the base 1702 and / or floor and a second end that sit above the support column 1706. The support arm 1704 can be configured to pivot relative to the base 1702 via a pivotable connection to the support column 1706. For example, as shown in FIGS. 18 and 20, the support arm 1704 can pivot relative to the base 1702 to a right side. In some embodiments, the support arm 1704 can similarly pivot relative to the base 1702 to a left side. In some embodiments, the support arm 1704 can pivot relative to the base 1702 in all degrees (e.g., 360 degrees). Alternatively, in some embodiments, the support arm 1704 can be limited to pivot to the right side and / or to the left side by a up to about 90 degrees, or between about 60 and about 120 degrees (inclusive of all sub-ranges and values therebetween), in each direction. The bassinet 1708 can be disposed on the support arm 1704. In some embodiments, the bassinet 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 bassinet 1708 can be configured to enable the bassinet to be extended relative to (e.g., translated a distance from or moved away from) the support column to a deployed configuration, as shown in FIG. 21. For example, the bassinet 1708 can be configured to be extended relative to the support column by up to about 2 feet, inclusive of all sub-ranges and values therebetween. In some embodiments, the support arm can have two sections, where one of the sections can extend out from or away from the support column. In some embodiments, the bassinet can be coupled to the support arm via one or more tracks, which allow the bassinet to be extended out from or translated away from the support column and / or support arm.

[0061] Similar to the bassinet support system 100, the bassinet support system 1700 can include a counterweight system including a counterweight 1710. The counterweight 1710 can be coupled to (e.g., fixedly attached to) an end of the support arm 1704 opposite the overhanging end of the support arm 1704. In some embodiments, the counterweight 1710 can have a weight such that, when the bassinet is in a retracted or stowed configuration relative to the base (e.g., when the bassinet is disposed partially, mostly, or entirely above the base, or when the support arm is aligned with the base), a center of gravity of the system can be substantially close to a center of the base, e.g., reducing or minimizing tipping or loss of stability. For example, as shown in FIG. 17, when the bassinet 1708 and support arm 1704 are aligned with the base, the center of gravity of the system can be substantially located at the center of the base. When the support arm 1704 and bassinet 1708 are deployed, e.g., pivoted away to the right or left, or when the support arm 1704 is extended, the center of gravity of the system may shift, e.g., due to the additional moment or torque applied by the weight of the bassinet (and infant disposed therein) and / or weight of the support arm relative to the support column. As such, to avoid tipping or loss of stability of the system, the counterweight 1710 can be set or selected to have a weight that sufficiently counterbalances the moment, torques, or forces applied by the combined weight of the bassinet, infant, and / or support arm.

[0062] FIGS. 18 and 20 depict a first deployed configuration of the bassinet, whereby the support arm has been pivoted relative to the base and therefore the center of gravity has shifted away from the center of the base 1702. FIG. 21 depicts a second deployed configuration of the bassinet, whereby the support arm has been extended in length and therefore the center of gravity has shifted further away from the center of the base, e.g., in a direction that the support arm 1704 has been extended. In some embodiments, in all configurations (e.g., all positions of the bassinet relative to the base, such as the retracted or stowed position, a pivoted position, or the fully extended or deployed position), the center of gravity can remain inside an area of stability of the system. In some embodiments, the area of stability of the system can be defined as an area within the four wheels of the base (e.g., within an area or volume having a perimeter spaced from the four wheels). The presence of the counterweight 1710 to counterbalance the weight of the bassinet and / or infant, compared to a system without a counterweight, can allow for further extension of the bassinet over the mother's bed while minimizing or reducing the torques or forces seen in the support column, and can keep the center of gravity of the system further away from unstable potential locations that can result in tipping of the system 1700.

[0063] In some embodiments, the counterweight can be coupled to (e.g., fixed to and / or contained within) the base. As shown in FIG. 2, in some embodiments, the counterweight can be placed on a side of the base (e.g., the left side of the base). When the bassinet is in the stowed or retracted position, the center of gravity of the system would also be to one side of center of the base and the system (also referred to as a cart) (e.g. the left side), but remain safely within an envelope or perimeter (e.g., a rectangular perimeter) having boundaries (e.g., edges and sides) defined by the wheels (e.g., four wheels) supporting the base and connecting the base to the floor, resulting in a stable system. In some embodiments, the system (e.g., the support arm and / or support column) can include physical rotation stops for mechanically limiting the rotational range of the support arm relative to the base such that the support arm can rotate only toward the opposite side of the cart than the counterweight is disposed (e.g., right). When the bassinet is fully deployed (e.g., fully extended and rotated 90 degrees to the right) (e.g., the maximum extension position of the bassinet away from the base for which counterbalancing may be needed for stability), the center of gravity can move to the right side of the base, but remain safely within the envelope or perimeter of support defined by the wheels of the base. Compared to embodiments including a counterweight included in or coupled to the support arm, more of the weight of the system including the counterweight in the base is disposed closer to the floor, and therefore the system including the counterweight in the base can have improved stability. The support column of the system including the counterweight in the base, however, can experience and need to withstand a larger moment from the extended bassinet compared to a support column of a system including a counterweight included in or coupled to the support arm. In some embodiments, as shown in FIG. 2, the counterweight can be disposed on only one side of the base (e.g., entirely on one side of a central axis of the base and opposite the direction the support arm projects from the base when the system is in a deployed configuration). In some embodiments, the counterweight can be disposed in or coupled to the base such that most of the counterweight is disposed on one side of the base (e.g., the majority of the counterweight is disposed on one side of the central axis of the base and opposite the direction the support arm projects from the base when the system is in a deployed configuration).

[0064] In some embodiments, as shown in FIGS. 3-7, the counterweight system can move in connection with the movement of the bassinet. In some embodiments, a movable counterweight is coupled (e.g., attached) to the support arm in a similar location as described above with respect to FIG. 1. In some embodiments, the counterweight and the bassinet (and the movement thereof) are mechanically linked so that movement of the bassinet causes associated simultaneous movement of the counterweight. For example, in some embodiments, extension of the bassinet away from the support column by the user causes the counterweight to extend away from the support column (e.g., in the opposite direction) simultaneously. In some embodiments, the bassinet, support arm, and counterweight are arranged such that when the counterweight is disposed closest to the support column (retracted), the bassinet is also closest to the support column (retracted), and, when the bassinet is extended away from the support column, the counterweight extends away from the support column (e.g., in the opposite direction). The mechanical linkage between the bassinet and the counterweight can be include a rack and pinion mechanism, gears attached to a link arm, a series of mechanical linkages, and / or a variety of other mechanical linkages.

[0065] By making the counterweight movable, a smaller counterweight can accomplish the same or a similar balancing effect as a fixed counterweight coupled to the support arm or the base (e.g., as shown and described with respect to FIGS. 1 and 2). This is owing to the greater moment or torque that can be generated by moving the counterweight to offset the torques and forces applied by the weight of the bassinet and / or baby. By reducing the weight of the counterweight, the overall weight of the system can be reduced, making movement of the system through hallways and within a room easier while maintain the same level of stability. In some configurations, the moveable counterweight has a weight between about 5 kg and about 30 kg, and / or can be configured to move between about 10 cm to about 30 cm when extending from a retracted to a deployed position. In some embodiments, the bassinet can be configured to move or extend a similar distance to the movement distance of the counterweight. In some embodiments, the counterweight can move a greater distance than the bassinet when each move between the retracted and deployed positions. In some embodiments, the counterweight can move a smaller distance than the bassinet when each move between the retracted and deployed positions. In some embodiments, the counterweight may have a spot (e.g., define a cavity) for additional storage of items.

[0066] In some embodiments, the bassinet can be connected to a rack gear, which interacts with a bassinet pinion gear. This bassinet pinion gear can be connected via a shaft to a counterweight pinion gear, which meshes with a counterweight rack gear. The size of the bassinet pinion gear and the counterweight rack gear can be varied to change the relative motion of the counterweight versus the bassinet. FIG. 6, for example, shows the system including a bassinet pinion gear that is two times larger than a counterweight pinion gear, so that the counterweight moves half the distance that the bassinet moves. In some embodiments, alternatively, the two pinion gears can have a 1:1 ratio and / or the counterweight can be geared to move a greater distance than the bassinet.

[0067] In some embodiments, as shown in FIG. 8, the moveable counterweight can be coupled to (e.g., located in) the base. For example, in some embodiments, the counterweight can have a retracted position disposed in the center of the base (e.g., aligned with a central axis of the base), and can be coupled to the bassinet via mechanical linkages such that the counterweight moves in an opposite direction of the bassinet. When the support arm pivots to the right, for example, the counterweight within the base can move to the left. In some embodiments, the movable counterweight can be fully contained within the base (e.g., in both the retracted position and the fully deployed position), such that no moving parts are visible. The advantage of this configuration is that, although the space for movement of the counterweight such that the movement distance may be limited, there are no pinch points which may risk injury to the caregiver when the counterweight moves. Additionally, the counterweight will always be able to move throughout the full range of motion without impingement.

[0068] In some embodiments, the counterweight can extend beyond the profile or outer perimeter of the base. The advantage of this configuration is that, although there is a risk of pinch points and a risk of objects external to the system blocking movement of the counterweight, the counterweight can have a greater range of motion and a smaller weight can effectively balance the system compared to a system in which the counterweight is container within the base throughout its entire range of motion.

[0069] In some embodiments, a rack and pinion system can be included in the system to move the counterweight in a direction opposite of the support arm's movement. In some embodiments, gear teeth can be disposed on the support column. The gear teeth can engage with a fixed rotation gear, which is also the pinion gear. The fixed rotation gear can engage with a rack gear which is rigidly connected to the counterweight. In some embodiments, when the support column rotates, the fixed rotation gear can rotate in an opposite manner such that the counterweight moves linearly in an opposite direction of the support arm.

[0070] In some embodiments, a series of link arms can be used to move the counterweight. One link arm can be fixedly (e.g., rigidly) attached to the support column. When the support column rotates, the rigidly attached link arm can move (e.g., be pulled) in the same direction. A pivot bar can be connected to the link arm on one end, fixedly (e.g., rigidly) attached to the base at a central pivot point and coupled to the counterweight at the second end to cause opposite motion of the bassinet coupled to the support column via the support rod and the counterweight. In some embodiments, the system can include a belt and pulley system to create the same relative motion.

[0071] In some embodiments, the moveable counterweight can include a suction / traction system including a suction mechanism (e.g., a suction cup) or other gripping mechanism which can provide a gripping force on a floor. For example, as shown in FIG. 14, the counterweight can include a floor anchoring mechanism configured to anchor at least a portion of the system to the floor. The floor anchoring mechanism can include one or more suction mechanisms (e.g., suction cups) on the bottom, and, when the counterweight is fully deployed, the counterweight can move down towards the floor and compress the suction cup(s) into the floor. The activated suction mechanism(s) can provide additional holding force, beyond the weight of the counterweight, and keep the base more securely anchored, while maintaining a smaller overall system or cart weight. The suction / traction system can include a mechanical release such that, prior to the counterweight being raised and moved back to a center or retracted position, the suction / traction can be broken by pulling up on one section of the area of the suction mechanism providing suction and breaking the seal. In some embodiments, such a mechanical release can allow for a very low force to remove the suction when desired, and a high force to remove the suction when not desired, preventing accidental release of the stabilizing suction force.

[0072] In some embodiments, the system can include multiple functions which can be locked and unlocked as desired by a user or clinician (e.g., via interaction with one or more release mechanisms). In some embodiments, the bassinet pivot, the support arm pivot, the support column height adjustment, the extension of the bassinet, and / or the roller wheels on the base all can be locked or unlocked. In some embodiments, two different users can interact with the locking features included in the system (e.g., both a clinician and a mother in a hospital bed) from two different positions (e.g., from opposite sides of the system, such as from the bed and from a position standing near the bed opposite the system). In some embodiments, the base can be wheeled next to a patient's (e.g., mother's) hospital bed by a clinician, and then locked into place with respect to one or more of the locking features. The system can include lock releases on both sides of the support arm such that the lock releases can be reached by both a user in a first position relative to the system (e.g., disposed in a hospital bed) and by a user in a second position relative to the system (e.g., a clinician standing nearby opposite the system from the first user) to reach the releases throughout all phases of use.

[0073] In some embodiments, a single release mechanism can control the release of all lockable functions (e.g., pivoting, height adjustment, bassinet extension, and / or wheel motion). In some embodiments, a multitude of release mechanisms can be included, with each release lever being independent capable of releasing one or more (e.g., two) functions independently of other release handles. In some embodiments, a pair of release handles can be located on each side of the support arm, near the bassinet, such that a patient sitting in the hospital bed can easily reach at least one of the release handles of the pair to lock and unlock motion of the support column, support arm, and / or bassinet without leaving the bed. This can allow the patient to bring the bassinet with the baby close to them to change a diaper, feed the baby, and / or provide intermittent or continuous touch to comfort a baby. This can also include positioning the bassinet directly above the mother while she lies in the patient bed. The patient can then return the baby (e.g., within the bassinet) to a position next to the patient bed without assistance and freely leave the bed, to use the restroom for example. By the system including a pair of interconnected release handles, one on either side of the support arm, both the mother and the clinician can access a release handle associated with the same lockable function(s).

[0074] In some embodiments, the pivotable support arm can also contain transport handles, or grips, for a clinician or user to push the system across the floor. There may also be a handle, or grip, on the distal end of the support arm, to allow for easy movement of the support arm without touching the bassinet.

[0075] In some embodiments, the system can include a different release which can control the release of only a subset of functions. For example, a pair of two releases, one on either side of the support arm, can control the locking and unlocking of the pivoting of the support arm 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 locks and bassinet pivot can be locked and unlocked independently. In some embodiments, other combinations of functions can be mapped to two or more release handles.

[0076] Including a pair, or two different handles which have the same purpose, but can be reached by different people in different positions relative to the system provides added flexibility. For example, including two different, but interconnected, pivot release handles can allow either the clinician or the mother to control a pivot release. In some embodiments, the two handles can be disposed on opposite sides of the support arm. In some embodiments, one set of handles can be on the support arm, and a second set of handles can be located near the transport handles. In some embodiments, it may be beneficial to have each moveable mechanism controlled by a single release. For example, in some embodiments, one release mechanism can control the movement of the support arm pivot and a separate release mechanism can control the motion of the bassinet pivot.

[0077] In some embodiments, when transporting the bassinet system from room to room, or across a room, the system can be positioned in a “transport position” (also referred to as a “transport configuration”). In the transport position, the support arm can be positioned in the fully retracted position. For example, the support arm can be aligned with the long axis of the base. The support column can be raised or lowered to achieve a desirable height for transport. For example, the support column can be raised or lowered so that handles (e.g., cart handles) of the system (e.g., used for pushing or pulling the entire system) are about 40″ above the floor, or between about 30″ and about 50″. The bassinet height can be as low as about 20″ to about 25″ from the ground (e.g., when the mother is in a hospital bed at its lowest setting) and can be raised significantly if the patient's (e.g., mother's) bed is raised. Once in transport position, the user can unlock the roller wheels on the base and begin to move the system by pushing on the transport handles (e.g., located on the distal end of the support arm).

[0078] In some embodiments, the system can include an interlock to prevent unlocking of the roller wheels unless the system is in transport position. In some embodiments, the system can include no interlock, and the wheel release can be transitioned to an unlocked configuration regardless of the position of the bassinet, support arm, and / or support column.

[0079] In some embodiments, the system includes a detent or pin which indicates to the user that the device is in transport mode. For example, the bassinet can include a pivot lock pin, which can be disposed in a pivot lock receiving hole when the bassinet is properly aligned with the transport arm for transport. FIG. 15 is a schematic illustration of an isometric view of a bassinet pivoted relative to a support arm of a bassinet support system, including a bassinet pivot lock pin and a bassinet pivot lock receiving hole, according to an embodiment.

[0080] In some embodiments, the system includes a pivot release mechanism that includes a pair of pivot release handles which are located on both sides of the support arm. Each pivot release handle of the pair can be interconnected via mechanical linkages to one or multiple pivot points on the support arm. At least one pivot point can be disposed between the support column and the support arm. As shown in FIGS. 9-11, in some embodiments, the system can include a release handle, which is connected via a series of linkages, including an over center mechanism, to a locking band. The band can wrap around a circularly shaped pivot. When the linkages are moved to the locked position, the system can move through an over center configuration and close the band tightly around the pivot. A large amount of force is thereby applied from the band onto the pivot. The resulting high frictional forces prevent movement of the pivot when external loads are applied by a clinician or patient while maintaining a continuous range of positions. In some embodiments, the series of mechanical linkages can connect two release handles, one on either side of the support arm, to both pivot release mechanisms, the bassinet pivot and the support arm pivot.

[0081] In some embodiments, the pivot release (also referred to as pivot release handles) can be lifted by the patient or clinician, which causes a release linkage to move towards the pivot release. This lateral motion of the release linkage causes a pull on a locking linkage which causes the distal end of the locking linkage to also translate towards the release and away from a pivot point in the center of a locking plate. When the locking linkage moves laterally towards the release, the locking plate can rotate in a way that causes the locking band to be pushed towards the pivot shaft, releasing pressure between the pivot shaft and the locking band. This motion allows the pivot shaft to rotate freely. When the pivot release is depressed back to the starting position, all motions are reversed, and the locking band applies a large clamping force to the pivot shaft. This results in a high frictional force on the pivot shaft and stops rotation of the pivot shaft.

[0082] In some embodiments, rather than the locking band, the system can be replaced with a geared pivot shaft and a keyed mechanism which engages with the gear teeth. The advantage of this mechanism is that the pivot shaft has interference with the locking mechanism and will not rotate without mechanical failure of the locking mechanism. In some embodiments, however, the pivot shaft can only be locked in discrete positions and overcoming the torque limit of the mechanism is likely to create permanent damage to the mechanism. In some embodiments, two different pivots can optionally be controlled by a single set of pivot releases.

[0083] As shown in FIGS. 9 and 10, in some embodiments, the pair of releases can control the motion of both the support arm pivot and the extension of the bassinet and counterweight. The two locking plates can be connected by a pair of locking plate interconnect linkages, such that both locking plates move in the same manner at the same time, and the locking bands lock and unlock simultaneously. One locking band can wraps around the support arm pivot and the second locking band can wrap around the counterweight brake drum. The counterweight brake drum can be connected to the counterweight pinion gear on one end, and the bassinet pinion gear on a second end via a gear shaft. When the support arm is extended, the gear shaft can spin, spinning both gears, which interact with the counterweight rack gear and bassinet rack gear, respectively. In some embodiments, a 2:1 gear ratio allows the bassinet to extend twice as far as the counterweight extends. When the band brake is closed on the brake drum, rotation of the gear shaft can be prevented, and any extension or retraction of the support arm and counterweight can be stopped.

[0084] In some embodiments, the system can include electric switches and actuators which provide the locking force. For example, a switch and linear actuator can provide motion to lock and unlock an overcenter band brake. In some embodiments, electric motors can engage with a series of gears or teeth to provide rotational motion. In some embodiments, the system can include a mechanism that includes a solenoid which drops into place to provide a mechanical lock when unpowered, and, when the lock is powered, the solenoid can retract and allow free motion of the rotational pivot.

[0085] In some embodiments, the wheels of the system are designed to roll freely during transport. The wheels can both roll and castor, allowing easy positioning of the cart in any direction and orientation. In some embodiments, all four wheels can freely castor. In some embodiments, two of the wheels can castor and two of the wheels can only roll. In some embodiments, the wheels can include or be coupled to a locking mechanism for use at the bedside. For example, it may be desirable to have locked wheels when adjusting the position of the bassinet or letting a baby sleep in the bassinet. In some embodiments, the system can include one or more wheel lock mechanisms, which can each include a wheel and a foot pedal which locks out all wheel motion in one position and allows free motion in a second position. A user (e.g., the clinician) can independently lock one or multiple wheel locks. In some embodiments, one, some, or all of the wheels can include or be associated with a respective wheel lock such that one, some, or all of the wheels can be lockable.

[0086] In some embodiments, a release mechanism can be located on the side of the support arm and can also control the wheel lock mechanism. In some embodiment, a mechanical cable can be connected from the release mechanism to each of the four wheels. In some embodiments, an electronic brake release can be included in the system such that engagement with the release mechanism generates an electrical signal which activates a clamp, over center mechanism, solenoid, and / or similar mechanism which locks and unlocks the wheels.

[0087] In some embodiments, the wheel release can be located near the transport handle such that the wheel release only accessible to a user within reach of the transport handles (e.g., the clinician).

[0088] In some embodiments, the height of the support column may need to be adjusted to position the bassinet at the ideal height over a bed. The adjustable height support column can include two sections, the upper section and lower section. The lower section can be rigidly connected to the base. The upper section can be connected via a pivot to the support arm. The upper and lower sections of the support column can be coupled (e.g., connected) via a linear bearing or bushing, which allows the upper section to move up and down relative to the lower section. The weight of the bassinet, support arm, upper section, and / or other mechanism(s) movable relative to the lower section can be significant, and therefore it is desirable to assist the clinician or user in raising the bassinet. In addition, a user, such as a patient (e.g., a mother) may have limitations from recent abdominal surgery and / or may have limited strength when raising and lowering the bassinet. In some embodiments, the system can include a height adjustment mechanism including a spring disposed to provide an upward facing spring force nearly equivalent to the weight of the portion of the system vertically movable relative to the lower section. In some embodiments, to create a smooth motion, a damping mechanism can also be included in the mechanism. In some embodiments, a spring system can be included which provides a constant force over the full range of motion of the upper section relative to the lower section and allows the bassinet to have the same range of travel as a typical hospital bed. In some embodiments, the system can include a constant force spring. In some embodiments, the height adjustment mechanism can include a series of constant force springs disposed (e.g., held in place) around a central shaft (e.g., disposed radially around the central shaft and having parallel longitudinally extending axes). In some embodiments, one end of a constant force spring(s) can be held in place on a spool attachment bracket which is fixedly (e.g., rigidly) connected to the lower section of the support column. The second end of the constant force spring(s) can be connected to a spring attachment plate which is fixedly (e.g., rigidly) connected the upper section of the support column. In some embodiments, the spool attachment plate can be located above the spring attachment plate, so that the constant force spring(s) always provide 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 can be included (e.g., placed in) the structure (e.g., within the upper and / or lower support column) to keep the motion smooth and avoid unwanted oscillations during use. While a constant force spring is described, in some embodiments, other springs can alternatively or additionally be included, including coil springs, torsion springs, etc. In some embodiments, a compressed gas cylinder can be included to provide a spring force, rather than or in addition to a metal spring. In some embodiments, a compressed gas cylinder can be used additionally or alternatively to provide a locking force on the height adjustment mechanism. As shown in FIGS. 12 and 13, in some embodiments, a height adjustment mechanism can include a height adjustment release connected via a cable to a mechanism which locks and unlocks a gas cylinder (also referred to as a gas spring cylinder). When the gas cylinder is closed, it prevents vertical movement of the assembly. When the height adjustment release is pulled, the attached cable is also pulled, which releases the gas trapped within the gas cylinder to expand or contract. FIG. 16 is a schematic illustration of a cross-sectional view of a gas cylinder of a bassinet support system, according to an embodiment.

[0089] In some embodiments, electrically powered mechanisms may can be used to change the height, including motors with a rack and pinion system, linear actuators, and / or a variety of other powered mechanisms.

[0090] In some embodiments, a release mechanism can provide a clamping force during normal use, which prevents any inadvertent changes in height of the support column. When a release lever is actuated, the clamping force can be released, and the user can then adjust the height of the bassinet as needed. The height release mechanism can be or include a single handle which only controls the height, or can be connected to one or more handles, which can control one or more functions.

[0091] In some embodiments, the system can include a powered linear actuator (e.g., within or coupled to the second section of the support column). The linear actuator can, for example, replace the spring and the damper. In response to the user pressing a button to raise the bassinet, the linear actuator can be powered and increase in length, urging the second section away from the first section and raising the bassinet. When the user presses a different button to lower the bassinet, the linear actuator can be powered and decrease in length, translating the second section toward the first section and lowering the bassinet. When no buttons are being pressed, the system can lock in place and maintain the existing height of the support column and the bassinet.

[0092] In some embodiments, the systems described herein can be configured to support a tray, table, or platform, instead of a bassinet. For example, as shown in FIG. 22, a system 2200 can be configured to support a tray 2218. The system 2200 can be structurally and / or functionally similar to other systems described herein, including bassinet support systems, but be adapted for supporting a tray. For example, the system 2200 can include a base 2202, wheels 2214, a support column 2206, a support arm 2204, and a counterweight 2210. Such components can be structurally and / or functionally similar to other similar components, including, for example, base 1702, wheels 1714, support column 1706, support arm 1704, and counterweight 1710, and / or the base, support column, support arm, and counterweight of system 100. Therefore, certain details of these components are not described again with reference to system 2200.

[0093] The tray 2218 can include a flat surface, and be configured to support an infant and / or one or more objects, e.g., over a bed of a patient. In some embodiments, the tray 2218 can include a raised edge, e.g., to help prevent objects from rolling off the tray. In some embodiments, the tray 2218 can be slidably coupled to the support arm 2204, e.g., such that the tray 2218 can be extended relative to the support arm 2204. Alternatively or additionally, the support arm 2204 can be extendable such that the tray 2218 can be extended away from the support column 2206 by extending a length of the support arm 2204. In some embodiments, the tray 2218 can be configured to extend by up to about 2 feet, or between about 1 feet and about 3 feet (inclusive of all sub-ranges and values therebetween), from its retracted or stowed position. In some embodiments, the tray 2218 can be pivotable relative to the support arm 2204, e.g., via a pivotable connection between the tray and the support arm 2204. For example, the tray 2218 can be configured to pivot to a left side or a right side by up to about 90 degrees in each direction. The tray can include one or more handles 2219a, 2219b, which can be configured to be grasped by a user to change a position, orientation, or configuration of the tray. For example, a user may grasp one or more of the handles 2219a, 2219b to extend or retract the tray along a length of the support arm 2204 and / or to rotate or pivot the tray relative to the base 2202. The support arm 2204 can also include one or more handles 2205, which can be used to push the system 2200 along a floor. As described with systems above, the system 2200 can 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.

[0094] The system 2200, by including a counterweight 2210, can be configured to maintain stability while the tray is deployed (e.g., extended and / or pivoted relative to its stowed configuration), similar to bassinet support systems described herein. Moreover, while it is not depicted in FIG. 22, it can be appreciated that any number of counterweight or stability features can be included in system 2200, including, for example, floor anchoring mechanisms and / or movable counterweights.

[0095] Designs of bassinet support systems are also disclosed herein. FIGS. 23-42 depict various views of the design of a bassinet 2300 and / or its components, as detailed below. As shown in FIGS. 23-42, a bassinet or infant tub can include a front wall, a back wall, and side walls. The front wall can include reduced height sections, e.g., to allow for a mother or other caregiver to have easier access to an infant disposed within the bassinet. In some embodiments, there can be two reduced height sections, e.g., one for each arm of a mother or caregiver. In some embodiments, there can be one continuous reduced heigh section. As shown in FIG. 31, an insert 2302 can be positioned in the bassinet in multiple positions, and be configured to conform to the contours of the inside of the bassinet. In a first position, as shown in FIG. 31, the insert 2302 can be positioned along the front wall, and therefore be positioned in an area of the reduced height sections. Such positioning can enable the insert to block or cover the lower height sections, e.g., during longer periods of when an infant may be left inside the bassinet (e.g., during sleep and / or transport of the infant). This can help shield the infant and / or further ensure that the infant is contained within the bassinet. In other words, when in the first position, the insert overlaps the reduced height sections and the front wall, thereby providing a substantially wall of a single height to prevent infants from rolling or otherwise falling over the side of the bassinet. In a second position, as shown in FIG. 33, the insert 2302 can be positioned along the back wall, e.g., for storage when it is not being used to block the lower height sections of the front wall.
