Description

Technical Field

The present disclosure is directed to a system or device for monitoring the configuration of equipment such as, for example, hospital equipment.

Background

Hospital equipment is often adjustable to conform to the individual attributes of a given patient or use. For example, a hospital bed is adjustable to help move a patient into or out of a bed or have handles that is configured to assist in the movement of patients. Also for example, a hospital bed is configured to maintain a patient in the bed during periods when the patient is unattended, e.g., during the night. Other equipment such as various types of hospital furniture is similarly adjustable.

To monitor a patient's interaction with equipment during periods when the patient is unattended, such as during the night or during periods when hospital personnel are not in a room with a patient, equipment include monitoring devices to identify unsuitable equipment configurations. For example, a hospital bed include a device to identify generally unsuitable configurations for the bed.

Conventional systems, however, typically do not provide sufficient information regarding patient use of equipment to attending staff. For example, in the case of a hospital bed, conventional indicators do not provide a care worker with sufficient information regarding hospital equipment with respect to varying conditions of various patient types such as, for example, information regarding both more able and less able patients. WO2007/075701A1 discloses a hospital bed that includes a base, a patient support system with pivotal sections (head-end, seat section, foot section), and an advanced control system. The control system features actuators that can adjust the position of these sections while allowing users to selectively increase speed for rapid adjustments when necessary. It also incorporates sensors to monitor angles and loads on various components to enhance functionality and safety.

The present disclosure is directed to overcoming the problems set forth above.

Detailed Description

Fig. 1A illustrates an exemplary system 10. System 10 is any suitable equipment system for a hospital or similar facility (e.g., a long term care facility, a nursing home, a residence, a rehabilitation facility, or a psychiatric facility) such as, for example, a patient care apparatus, patient handling equipment, patient transfer apparatus and systems, a hospital bed, long term care beds, a patient lifter, standing aids, or other hospital furniture such as a patient examining chair, furniture for use in a medical procedure, a restraining device for a patient, a physical therapy device, or any other suitable hospital, rehabilitation, and/or long term care equipment. System 10 include a plurality of adjustable features for patient comfort.

System 10 include a plurality of casters 12 that is locked by one or more brakes 14, respectively. System 10 also include a frame 16. Frame 16 is any suitable frame such as, for example, a height adjustable frame for raising and lowering the bed and a patient supported thereon. For example, frame 16 is a bed frame such as, for example, a hospital bed frame or a frame for a long term care bed. Also, for example, frame 16 is a bed frame that is selectively adjustable between a substantially horizontal position and an inclined position. For example, an upper portion of frame 16 corresponding to an upper portion of a patient's body, (e.g. backrest or torso portion of the bed frame), is selectively raised so that an upper portion of frame 16 is inclined from a horizontal plane (e.g., so that an upper portion of a patient's body is inclined such as, for example, for patients for whom remaining in a horizontal position is unsuitable). As schematically illustrated in Fig. 1B, an upper portion 17 of frame 16 is inclined at any suitable angle "A" from a horizontal position such as, for example, between about 20 degrees and about 40 degrees, or e.g. about 30 degrees. In one embodiment, system 10 is a bed or mattress with multiple patient support sections (e.g. head/back rest section, seat section, leg section and foot section) and/or multiple corresponding sections of bed frame 16, one or more or all of which is movably adjustable relative to one another, thus for example, allowing a back rest section to pivot and move between a substantially horizontal to a substantially, vertical seated position and various inclined angles there between. In another embodiment, system 10 include an inflatable mattress with multiple inflatable cells and/or multiple inflatable bed sections for support a patient. Referring back to Fig. 1A, system 10 also include a first set of side rails 18 (e.g., panels) that is moveable between upper and lower positions and/or a middle position. System 10 also include a second set of side rails 20 that is disposed at either side of system 10. For example, one or more side rails 20 is disposed at a patient head end of system 10 (e.g., in the case that system 10 is a hospital bed or a bed for a similar facility such as the ones disclosed above). Side rails 20 is also movable between a lower position and an upper raised position as illustrated in Fig. 1A. In one embodiment, side rails 20 is movable between a raised uppermost position, middle/mid-raised position and lower position. Side rails 18 and side rails 20 is used, for example, to secure and maintain a patient safely on an upper surface of system 10.

System 10 also include a headboard 22 and a foot rest 24 (for example, when system 10 is a hospital bed or other similar type of hospital equipment or equipment, e.g., for long term care or physical rehabilitation). Headboard 22 and foot rest 24 is substantially stationary (e.g., not movable or configurable). It is also contemplated that system 10 also have movable and/or configurable headboards and/or foot rests.

System 10 include electrically, hydraulically, and/or pneumatically operated actuators 25 and 27. For example, actuators 25 and 27 is integrated as part of frame 16 and/or side rails 18 and 20, or provided externally to one or more elements of system 10. Actuators 25 and 27 of system 10 facilitate an operation of system 10. For example, actuators 25 and 27 operate to adjust a height of system 10 and/or a position of side rails 18 and/or side rails 20. For example, as illustrated in Fig. 1B, actuator 25 selectively control an inclination of system 10, and move upper portion 17 to be at a desired angle "A" from a horizontal plane (e.g., a substantially flat floor). Actuators 25 and 27 is any suitable actuators for adjusting equipment. In another exemplary embodiment, actuators 25 (e.g. pump, exhaust and/or valve actuators) control inflation and/or deflation of one or more inflatable cells and/or inflatable sections of a mattress.

System 10 include a plurality of sensors 29 for sensing and detecting the position and/or properties of system 10 and its components. For example, sensors 29 sense a position of casters 12, brakes 14, frame 16, bed side rails 18 and/or side rails 20. In one embodiment, one or more sensors 29 is positioned to detect whether casters 12 are raised or lowered, the locked or unlocked position and/or state of brakes 14, the height of bed frame 16 and/or the position of one or more sections of a bed or bed frame 16 (e.g. lowered or elevated backrest section, seat section, leg section and/or foot section), and the elevated and/or lowered position of side rails 18, 20. In another embodiment, sensors 29 is used to provide information regarding a state of operation or a characteristic of a component of system 10, such as the inflated and/or deflated state, degree of inflation and/or deflation, the rate of inflation and/or deflation of a mattress or portion thereof (e.g. select inflatable cells of a mattress, turning bladders, backrest section, seat section, leg section and/or foot section), rate of air flow through a mattress or coverlet, etc. Sensors 29 is any suitable device for sensing a position and/or operation of elements of system 10 such as, for example, an active transducer, a passive transducer, a pressure sensor, magnet and hall sensors, and/or a bidirectional sensor. Sensors 29 is disposed at one or more locations of system 10 so as to provide measurements and other information, for example, for use in providing a medical professional or other caregiver data used for ascertaining a configuration of system 10. For example, sensors 29 provide output that is used to notify personnel of either suitable or unsuitable configurations of system 10 in relation to various patients.

Fig. 2 illustrates an exemplary indicator device 30. Indicator device is any suitable device for providing information (e.g., output from sensors 29 and/or other sources) as to a configuration of system 10. For example, as illustrated in Fig. 2, indicator device 30 is a configuration indicator for providing an indication of the state of configuration of system 10 such as, for example, a hospital bed indicator, patient support indicator, a patient handling equipment indicator, a hospital furniture indicator, a patient transfer system indicator, a patient lifter and/or hoist indicator, or any other suitable type of indicator used in a hospital or similar facility (e.g., for equipment used for physical rehabilitation, long term care, psychiatric care, or a residence). Indicator device 30 include a housing 32 (e.g., any suitable housing or casing for an indicator device). Housing 32 include an attachment portion 34, which for example is a separate component or an integral part of housing 32. For example, attachment portion 34 is formed integrally with housing 32 as a part of the housing 32 itself. Attachment portion 34 is, for example, a hook, clamp, clasp, snap, magnet, opening, connector, or other element suitably structured to be mounted on system 10 for attaching indicator device 30 to a portion of system 10. Attachment portion 34 include a hook or other opening 36 that is wide enough to accommodate a portion of the various elements of system 10. For example, attachment portion 34 is dimensioned to fit a width of a portion of frame 16, a rail attached to system 10, a portion of foot rest 24, a portion of headboard 22, and/or a portion of side rails 18 and 20. Attachment portion 34 is, for example, adjustable to fit varying dimensions of different portions of system 10. For example, attachment portion 34 is an adjustable hook. In an exemplary embodiment, indicator device 30 and housing 32 is portable. For example, housing 32 is sized so that it can be held and easily carried or moved by hand by a user. For example, housing 32 is about the size of a person's hand or is sized to be larger than a user's hand (but may still be, for example, portable). It is also contemplated that in one embodiment, housing 32 is substantially stationary (for example, substantially fixed in place at a given location of system 10).

Indicator device 30 is operatively associated with and sensors 29, and/or controller 35 and/or system 10. In one embodiment, indicator device 30 include a coupling element that couples indicator device 30 electrically to sensors 29 and/or a controller 35. Controller 35 is any suitable control device for controlling operation of system 10 such as, for example, a control device including a central processing unit and other suitable elements for receiving input and generating output (e.g., a processing unit or any other suitable type of automated and/or computer controller for facilitating automated control). Controller 35 is disposed at a portion of system 10 such as, for example, at frame 16 or any other suitable location of system 10. Indicator device 30, sensors 29, and controller 35 is coupled by any suitable technique such as, for example, a wireless coupling (e.g., one including a transceiver) or a cable such as for example, an electrical cable. For example, indicator device 30 and sensors 29 is coupled via electrical lines to controller 35 that is disposed on frame 16. For example, indicator device 30, sensors 29, and controller 35 is coupled by a cable connection that reduce an amount of wireless noise that might potentially interfere with other equipment disposed in a vicinity of system 10. Also, for example, indicator device 30, sensors 29, and controller 35 is coupled by any suitable technique for ensuring a reliable link between sensors 29, indicator device 30, and controller 35.

Housing 32 have any suitable structure or size for allowing indicator device 30 to be moved by personnel using system 10 (e.g., medical personnel or other care givers) and placed in positions on system 10 that is convenient for attending personnel and is seen when a patient is left alone (e.g., during a period when a patient is resting or sleeping). For example, indicator device 30 is positioned at or near a location of system 10 that is close to a doorway or facing a front portion of a screen or other device for providing privacy (e.g., a curtain, divider, or other device affording privacy to a patient or other user of system 10). Also, for example, indicator device 30 is placed at any location of system 10 visible to attending personnel such as, for example, frame 16, side rails 18, side rails 20, headboard 22, foot rest 24, handle or any other suitable location of system 10. In one embodiment, indicator device 30 is coupled to, latch on, hang on an edge or upper surface of frame 16, side rails 18, side rails 20, headboard 22, foot rest 24, handle or exposed ledge of system 10.

In one embodiment, first indicator element 41 is configured as a lighting element, such as LED lights and/or other light source, and is illuminated when indicator device 30 is in operation. For example, first element 41 project different colors or flashing colors corresponding to different states of system 10, clearly notifying a user as to a state of system 10 and/or communicating alarm notices/alerts. In one embodiment, first indicator element 41 encircle one or more display elements 42, 44 forming a single display. In one embodiment, the display elements 42, 44 include and/or is configured as, for example, one or more display screens and/or any suitable number of LEDs, lamps or other light elements and sources for illumination elements or surfaces disposed in any suitable arrangement for providing notification to attending personnel. Light unit 40 also include a second indicator element 50 that is an integral portion of housing 32 or a separate component that is disposed at a bottom portion of housing 32. Second indicator element 50 is configured to direct light generated by light unit 40 downwardly when indicator device 30 is in use. For example, in one embodiment, second indicator element 50 is configured as a lighting element, such as LED lights or other light source. In one embodiment, the display, display elements, first indicator element 41 and/or second indicator element 50 include and/or is configured as lighting elements which illuminate, project colored and/or flashing lights to notify a user as to a state of system 10 and/or alert/alarm condition; these display, display elements and/or first indicator element 41 coordinate light projections, simultaneously project light and/or independently project light relative to one another.

Indicator device 30 also include an input unit 46. Input unit 46 is any suitable unit for a user of indicator device 30 to provide input, such as system 10 and/or patient data, to indicator device 30 such as, for example, a button console, a keypad, a touchscreen, or any other suitable unit for receiving data from a user based on tactile, visual, audio, or any other suitable technique for providing input.

As discussed above, light unit 40 include one or more or a plurality of LEDs, lamps or other light elements and sources. These light sources of light unit 40 is operated in a plurality of modes. For example, light unit 40 operate to indicate a suitable and/or unsuitable configuration of system 10 (e.g., a suitable-for-patient status or an unsuitable-for-patient status). For example, light unit 40 is formed of one or more LEDs, lamps or other light elements and sources. Also for example, light unit 40 generate light of any suitable wavelength such as, for example, a plurality of different colors including red, orange, yellow, green, blue, violet, and white. For example, light unit 40 include a plurality of lights including green, yellow, amber, and or red lights. The lights also be able to flash and project lights of different patterns.

Light unit 40 include one or more LEDs, lamps, light elements or sources configured to direct light downwardly (with respect to a longitudinal direction of indicator device 30, such as in a direction moving away from element 50) from at least one light element. Light unit 40 include one or more LEDs, lamps and light elements configured to direct light in a lateral direction from the sides of indicator device 30 in a sideways direction, upward from indicator device 30, frontwards (e.g., forwardly) from indicator device 30, rearwards from indicator device 30, diagonally from indicator device 30, or any other suitable direction from indicator device 30. For example, light unit 40 is configured to direct light sideways and/or upwardly from indicator device 30, and/or frontwards and/or downwards.

Fig. 3A illustrates an exemplary embodiment of an indicator device. Indicator device 30a is generally similar to indicator device 30. Indicator device 30a include a second display element 44a and an input unit 46a that is the same or generally similar to second display element 44 and input unit 46, respectively. Indicator device 30a is an exemplary indicator device for a bed (e.g., for use in a hospital, physical therapy center, long term care facility, residence, psychiatric care center, rehabilitation center, and/or any other suitable location for providing an indicator device for a bed). As illustrated in Fig. 3B, second display element 44a include a brake indicator 52 that illuminate when brakes are applied (e.g., when brakes 14 are applied), a side-panel position indicator 54 that illuminate when side panels are raised and/or lowered (e.g., when side rails 18 and/or side rails 20 are raised), a bed height indicator 56 that illuminate when the bed/system 10 is in a raised and/or lowermost position (e.g., when frame 16 is in an uppermost and/or lowermost position), a patient-exit indicator 58 that illuminate when system 10 is in a configuration in which a user exit and/or step off of system 10 (e.g., in the case that system 10 is a bed, patient-exit indicator 58 indicate that it is a suitable time for a patient to leave the bed, for example when frame 16 is in its lowest position and side rails 18, 20 are in their lowered positions) or that a patient has actually exited system 10 (e.g., sensor 29 is a pressure sensor or any other suitable sensor for detecting that a patient has exited system 10), and a backrest-inclination indicator 59 (e.g., a bed inclination indicator) that indicate when frame 16 is in an angled configuration exceeding a predetermined threshold (e.g., when a portion of frame 16 corresponding to an upper portion of a patient's body is angled greater than a threshold angle from a horizontal plane such as, for example, 30 degrees, 35 degrees, 25 degrees, or 20 degrees). Brake indicator 52, side-panel position indicator 54, bed height indicator 56, patient-exit indicator 58, and/or backrest-inclination indicator 59 provide attending personnel (e.g., a nurse or other care personnel) with an indication of the state of each of the configurable elements of system 10 (e.g., with respect to the activities of a patient or other user of system 10). Brake indicator 52, side-panel position indicator 54, bed height indicator 56, patient-exit indicator 58, and/or backrest-inclination indicator 59 provide output based on a configuration of system 10 sensed by one or more sensors 29 and a patient type input to input unit 46a as described below. In other embodiments, indicator device 30a also include a mattress inflation and/or deflation indicator providing a user with an indication of mattress pressure in one or more sections of the mattress (e.g. seat section of the mattress) or the rate of inflation/deflation of one or more mattress sections; patient turning indicators to provide notice when turning bladders are activated to assist with turning of a patient; and/or air flow indicator for determining the rate of air flow through a mattress (such as a low air loss mattress) or coverlet.

As illustrated in Fig. 3C, input unit 46a, e.g. user interface, include a first input device 60, a second input device 62, and third input device 64. Input devices 60, 62, 64 is any suitable type of switch for allowing a user to input information to input unit 46a such as, for example, push-button switches, dials, levers, or touchscreen devices. First input device 60 is used by an operator to set parameters for system 10 when system 10 is not being moved between different locations or positions (e.g., in the case when system 10 is substantially stationary such as, for example, when system 10 is a bed for accommodating a patient therein). For example, first input device 60 is activated for a situation applicable to all users or patients (e.g., a universal setting, or an all-patient type setting). For example, when first input device 60 is activated, indicators 52, 54, 56, 58, and 59 all illuminate to indicate a suitable condition (e.g., green) to attending personnel or is not illuminated at all. Also, for example, when first input device 60 is activated, brake indicator 52 illuminate as unsuitable (e.g., red or other color denoting unsuitability) when brakes 14 are off (e.g., and brake indicator 52 illuminate as suitable when brakes 14 are on and system 10 is locked in a substantially stationary position).

Second input device 62 is used by an operator to set system 10 into a configuration deemed suitable for a first category or type of user of system 10. For example, second input device 62 is used to set system 10 into a configuration deemed suitable for a patient who is unlikely to fall out of system 10 unintentionally (e.g., a user who is in generally good or fair physical condition such as, for example, a patient who is sufficiently stable to be able to get into and out of system 10 unaided for the case in which system 10 is a bed, e.g., a stable patient type). For example, second input device 62 allow for an indication of a suitable bed configuration even when one or more of the features of system 10 is disengaged, such as for example when side rails 18 and/or side rails 20 are in a lowered or disengaged position. For example, when second input device 62 is activated, brake indicator 52 is illuminated to display an unsuitable configuration (e.g., red) when one or brakes 14 are unlocked (e.g., it is deemed unsuitable for even healthy users to exit system 10 when the brakes are off), but display a suitable configuration (e.g., green) when all of brakes 14 are locked. For example, when second input device 62 is activated, side-panel position indicator 54 is not illuminated or is illuminated to display a suitable configuration (e.g., green) when one or more side rails 18 and 20 are either in a raised or lowered position. Similarly, when second input device 62 is activated, bed height indicator 56 is not illuminated or be illuminated to display a suitable configuration (e.g., green) when frame 16 is either in a raised or lowered position. It is also contemplated that when second input device 62 is activated and frame 16 is in a raised position, bed height indicator 56 is illuminated to display an unsuitable configuration (e.g., red). Also for example, when second input device 62 is activated, patient-exit indicator 58 is not illuminated or remain in a suitable configuration (e.g., green illumination) deeming it suitable for healthy patients to climb on or off system 10 at any time. Further for example, when second input device 62 is activated, backrest-inclination indicator 59 is not illuminated or remain in a suitable configuration (e.g., green illumination) deeming it suitable for healthy patients to be at any suitable inclination angle "A" illustrated in Fig. 1B.

Third input device 64 allow an operator to configure system 10 for a user generally associated with higher levels of instability and uncertainty (e.g., an unstable patient type). For example, third input device 64 configure system 10 for use by a user who is relatively more likely than other users to fall out of system 10 unintentionally or who is otherwise too unstable to be able to get into or out of system 10 unaided. In a setting activated by third input device 64, system 10 is deemed to be in a suitable configuration only when most or all of the features of system 10 are engaged (e.g., all of the features of system 10 designed to help maintain a user within or on system 10 are engaged such as, for example, side rails 18 and side rails 20 being in an upright and locked position). For example, when system 10 is a bed, all of the features of system 10 designed to maintain a patient in bed is activated based on an operator activating third input device 64. Accordingly, when third input device 64 is activated, brake indicator 52 is illuminated to be suitable (e.g., green) when brakes 14 are on but is illuminated to be unsuitable (e.g., red) when brakes 14 are off, side-panel position indicator 54 is illuminated to be suitable (e.g., green) when side rails 18 and 20 are in an upright position but is illuminated to be unsuitable (e.g., red) when one or more side rails 18 and 20 are in an unlocked or lowered position, bed height indicator 56 is illuminated to be suitable (e.g., green) when frame 16 is in a lowermost position but is illuminated to be unsuitable (e.g., red) when frame 16 is in any position other than a lowermost position, and patient-exit indicator 58 is illuminated to be unsuitable at any time that one or more sensors 29 detect that a patient is exiting or has exited system 10. Also, when third input device 64 is activated, backrest-inclination indicator 59 is illuminated to be suitable (e.g., green) when angle "A" is equal to or greater than a predetermined value (e.g., about 30 degrees, about 25 degrees, about 35 degrees, or about 20 degrees) and is illuminated to be unsuitable (e.g., red) when angle "A" is below the predetermined value (e.g., indicating to attending personnel that a patient should remain in an inclined position instead of a flat position).

First input device 60, second input device 62, and third input device 64 is operatively associated with and/or operate in conjunction with controller 35, indicator device 30a, and/or sensors 29 to cause, for example, the LEDs, lamps or other light elements or sources of light unit 40 and second display element 44 to illuminate to indicate whether the bed is in the configuration suitable for meeting the respective criteria of first input device 60, second input device 62, and/or third input device 64. For example, when system 10 is deemed to be configured in an appropriate manner, light unit 40 illuminate in a first mode (for example, light unit 40 illuminate in green, white, purple, blue, or another predetermined color, or in a steadily-lit manner). Also, for example, when system 10 is deemed to be configured in an inappropriate manner, light unit 40 illuminate in a second mode (for example, light unit 40 illuminate in a different color, e.g. red, orange, yellow, or other predetermined color, or in a flashing manner). Further, for example, light unit 40 is designed to illuminate in any manner that would intuitively notify attending personnel as to the status of the configuration of system 10 (for example, a red flashing mode of illumination intuitively notify attending personnel of an inappropriate configuration of system 10, while a steady green mode of illumination intuitively notify attending personnel of an appropriate configuration of system 10). Indicator device 30a additionally include audio features to provide further notification to attending personnel in suitable situations. For example, when system 10 is employed in a facility for psychological treatment, indicator device 30a include audio features that provide notification to attending personnel of an inappropriate configuration of system 10 (such as, for example, a high-pitched audio alert to notify attending personnel of an inappropriate configuration).

Display elements 42, 44, brake indicator 52, side-panel position indicator 54, bed height indicator 56, patient-exit indicator 58, and/or backrest-inclination indicator 59 is illuminated similarly as described above with reference to light unit 40. For example, brake indicator 52 is illuminated when one or more brakes 14 have been applied. Also, for example, side-panel position indicator 54 is illuminated when side rails 18 and/or side rails 20 are raised. Further, for example, bed height indicator 56 is illuminated when system 10 is in a lowermost position. Additionally, for example, patient-exit indicator 58 is illuminated when system 10 is deemed to be in a configuration suitable for a patient to be moved onto or off of system 10. Also, for example, brake indicator 52, side-panel position indicator 54, bed height indicator 56, patient-exit indicator 58, and/or backrest-inclination indicator 59 is of a type that illuminate in different colors (for example, they is illuminated red when an associated feature of system 10 is not in an inputted or indicated configuration, or green when an associated feature of system 10 matches an inputted or indicated configuration). Also, for example, brake indicator 52, side-panel position indicator 54, bed height indicator 56, patient-exit indicator 58, and/or backrest-inclination indicator 59 is configured to illuminate only at times when the bed is sensed to have been actuated into a configuration associated with those indicators. In tandem with indicators 52, 54, 56, 58, and/or 59 being illuminated, light unit 40 also be illuminated to provide a consistent notification to attending personnel based on the illumination of the indicators (e.g., light unit 40 disposed on any portion of indicator device 30 is illuminated to provide notification to attending personnel located at a significant distance away from system 10).

Fig. 4 illustrates an exemplary configuration of system 10 deemed suitable for a user such as, for example, a stable patient (e.g., a relatively healthy patient who is able to maintain a position on system 10). In addition to indicator device 30 and/or indicator device 30a, a second indicator device 130 is provided that is positioned for use by a patient utilizing system 10. Accordingly, a patient is allowed to use indicator device 130 to control and/or provide input to system 10 similarly to as described above with reference to indicator device 30 and indicator device 30a. Also, for example, a patient is provided instead with a different controller configured to control some features of system 10, but not all of the features described above with reference to indicator device 30 and indicator device 30a. Further, for example, a patient is provided with no indicator device or controller for controlling system 10.

In the configuration illustrated in Fig. 4, light unit 40 emit a green light indicative of an appropriate configuration (e.g., a suitable bed configuration), for example with frame 16 being in a lowered position, brakes 14 being applied, and at least one of side rails 18 and side rails 20 being in a lowered position. Also, for example, indicator device 30 and/or indicator device 130 indicate that system 10 is in a suitable or appropriate configuration when only one of (for example, each of) side rails 18 and side rails 20 is lowered and the other is raised, only side rails or side panels on one side of system 10 are lowered, both side rails 18 and side rails 20 are lowered, or all side rails on all sides of system 10 are lowered (e.g., when system 10 is in a lowered position, for example). Also, for example, indicator device 30 is configured to emit a warning sound when system 10 is in this configuration, serving as a notification to medical personnel or attending personnel such as a care giver that a patient has initiated a given configuration and therefore the patient's use of system 10 should possibly be monitored. Accordingly, indicator device 30 (and/or indicator device 30a and indicator device 130) provide functionality by allowing system 10 to be set into a configuration (e.g., by using input unit 46) in which one or more of the features of system 10 is, for example, lowered or otherwise deactivated. In particular, this setting allow a user (e.g., who is physically able) to get off or onto system 10 when one or more of side rails 18 and/or side rails 20 is lowered without indicator 30 providing notification (e.g., notification of an inappropriate configuration by providing illumination as described above or by raising an alarm). Further, system 10 help to substantially prevent a patient who is relatively unstable or not physically able from climbing off of system 10 (e.g., by providing notification to attending personnel via indicator device 30).

Fig. 5 illustrates a similar configuration of system 10 as Fig. 4, but with indicator device 30 being set for a patient who is relatively unstable (e.g., relatively unhealthy or not physically able). For example, this configuration is associated with a configuration of system 10 in which third input device 64 has been activated. In this setting, light unit 40 emit a warning light (for example, a red or amber illumination notifying attending personnel that one or more of side rails 18 and/or side rails 20 is in a lowered position, because there is a patient who is not physically stable in system 10). Indicator device 30 cause light unit 40 to emit a green light (e.g., or other color indicating for example suitability) when it is determined that: brakes 14 are applied, frame 16 is in a lowered position (e.g., a lowermost position), the majority of side rails 18 and side rails are in raised positions (e.g., at least three out of four of side rails 18 and side rails 20), and an exit alarm is activated (e.g., an audio warning device included, for example, as part of indicator device 30, frame 16, and/or any other suitable portion of system 10). For example, in the case in which system 10 is a bed such as a hospital bed, indicator device 30 cause light unit 40 to emit a green light only, for example, when system 10 is sensed to be in an appropriate setting for a physically unstable patient (e.g., all of the appropriate features suitable to be activated for that patient are activated).

Fig. 6 illustrates an exemplary system 10b. System 10b is a system for assisting a user's movement in a hospital or other care facility such as, for example, a patient lifting system or a patient hoist. System 10b is, for example, a lifting device for assisting a patient into or out of a bed or other piece of equipment.

Exemplary system 10b include a mast 70b that is mounted on a chassis 72b. Chassis 72b include a plurality of chassis legs 73b for stabilizing system 10b (e.g., stabilizing legs). A plurality of casters 74b is mounted on chassis 72b, for example at distal ends of legs 73b, allowing users and/or attending personnel to move system 10b as desired. Brakes 76b is disposed at respective casters 74b to selectively lock casters 74b and substantially prevent a movement of system 10b. A patient interface 78b (e.g., a patient support interface) also be mounted to mast 70b, and is used for securing a patient to system 10b during transport (e.g., via straps or other attachments for holding a patient). An indicator device 30b is attached to any suitable portion of system 10b, such as a member 80b or handle. Indicator device 30b is disposed at any other location of system 10b such as, for example, mast 70b, chassis 72b, or patient interface 78b. System 10b also include one or more actuators 27b, sensors 29b, and a controller 35b that operate generally similarly to actuators 27, sensors 29, and controller 35.

Fig. 7A illustrates exemplary indicator 30b. Indicator 30b include a second display element 44b that is generally similar to second display element 44a, and an input unit 46b that is generally similar to input unit 46a. As illustrated in Fig. 7B, second display element 44b include a plurality of indicators that is generally similar to the indicators of second display element 44a. For example, second display element 44b include a brake indicator 52b that illuminate when brakes are applied (e.g., when brakes 76b are applied), an interface-loaded indicator 54b that illuminate when a patient has been loaded on patient interface 78b, a mast-raised indicator 56b (e.g., a mast-height indicator) that illuminate when mast 70b is extended or raised to a predetermined length or height (e.g., when mast 70b is raised to a height of, for example, 200 centimeters or more, 180 centimeters or more, 210 centimeters or more, or 220 centimeters or more), a chassis-legs-locked indicator 58b that illuminate when chassis legs 73b are in a closed position (e.g., chassis legs 73b are in a closed and/or locked position that further stabilize a vertical orientation of system 10b), a standstill-time indicator 59b that illuminate when system 10b is in a stationary position for a predetermined amount of time (e.g., about 5 minutes, or about 10 minutes) but brakes 76b have not been activated, and an interface-connected indicator 61b that illuminate when patient interface 78b is suitably connected to mast 70b (e.g., when a solid, reliable connection is made between patient interface 78b and mast 70b). For example, interface-connected indicator 61b indicate that slings, safety belts and other components used to secure a patient to patient interface 78b are attached correctly (e.g., by illuminating to indicate suitability) or incorrectly (e.g., by illuminating to indicate unsuitability). Also, for example, second display element 44b include a battery-status indicator 63b that illuminate based on a battery level status of a power source of system 10b (e.g., illuminating to indicate suitability when battery power is sufficient and/or illuminating to indicate unsuitability when battery status is low). Brake indicator 52b, interface-loaded indicator 54b, mast-raised indicator 56b, chassis-legs-locked indicator 58b, standstill-time indicator 59b, interface-connected indicator 61b, and/or battery-status indicator 63b provide attending personnel (e.g., a nurse or other care personnel) with an indication of the state of each of the configurable elements of system 10b (e.g., with respect to the activities of a patient or other user of system 10b). Brake indicator 52b, interface-loaded indicator 54b, mast-raised indicator 56b, chassis-legs-locked indicator 58b, standstill-time indicator 59b, interface-connected indicator 61b, and/or battery-status indicator 63b provide output based on a configuration of system 10b sensed by one or more sensors 29b and a patient type inputted to input unit 46b.

As illustrated in Fig. 7C, input unit 46b include a first input device 60b, a second input device 62b, and a third input device 64b that is generally similar to the input devices of input unit 46a. Similar to first input device 60, first input device 60b is used by an operator to set parameters for system 10b when system 10b is not being moved between different locations or positions (e.g., in the case when system 10b is substantially stationary). For example, first input device 60b is activated for a situation applicable to all users or patients (e.g., a universal setting, or an all-patient type setting). For example, when first input device 60b is activated, indicators 52b, 54b, 56b, 58b, 59b, 61b, and 63b all illuminate to indicate a suitable condition (e.g., green) to attending personnel or is not illuminated at all. Also, for example, when first input device 60b is activated, brake indicator 52b illuminate as unsuitable (e.g., red or other color denoting unsuitability) when brakes 76b are off (e.g., and brake indicator 52b illuminate as suitable when brakes 76b are on and system 10b is locked in a substantially stationary position). Also, for example, battery-status indicator 63b illuminate as unsuitable when a battery or power source of system 10b is low and illuminate as suitable when a battery or power source of system 10b has sufficient reserve power.

Second input device 62b work in conjunction with indicators 52b, 54b, 56b, 58b, 59b, 61b, and/or 63b in a manner similar to second input device 62 and the indicators of second display element 44a. For example, when second input device 62b is activated (e.g., for a user who is in generally good or fair physical condition), indicators 52b, 54b, 56b, 58b, 59b, 61b, and/or 63b generally remain in a suitable configuration (e.g., illuminating green or other color denoting suitability), or is not be illuminated at all, except in a number of situations. For example, when second input device 62b is activated, brake indicator 52b is illuminated as unsuitable (e.g., red or other color denoting unsuitability) when all brakes 76b are off, mast-raised indicator 56b is illuminated as unsuitable when a certain length or height is exceeded (e.g., when the height is in excess of 200 cm, in excess of 220 cm, or in excess of 240 cm, for example), and interface-connected indicator 61b is illuminated as unsuitable when one or more sensors 29b detect that a reliable connection has not been established. Also, for example, battery-status indicator 63b illuminate as unsuitable when a battery or power source of system 10b is low and illuminate as suitable when a battery or power source of system 10b has sufficient reserve power.

Third input device 64b work in conjunction with indicators 52b, 54b, 56b, 58b, 59b, 61b, and/or 63b in a manner similar to third input device 64 and the indicators of second display element 44a. For example, when third input device 64b is activated (e.g., for a user who is in generally poor physical condition), indicators 52b, 54b, 56b, 58b, 59b, 61b, and/or 63b illuminate in a suitable configuration (e.g., illuminating green or other color denoting suitability) in only a number of situations. For example, when third input device 64b is activated, brake indicator 52b is illuminated as suitable when (e.g., green or other color denoting suitability) when all brakes 76b are on, interface-loaded indicator 54b is illuminated to alert attending personnel (e.g., as yellow or some other suitable color denoting that particular attention should be paid) whenever a patient is loaded on patient interface 78b, mast-raised indicator 56b is illuminated as unsuitable when a certain length or height is exceed (e.g., when the height is in excess of, for example, 160 cm, 180 cm, or 200 cm), standstill-time indicator 59b is illuminated as suitable when system 10b has remained stationary but brakes 76b have not been applied for less than a predetermined amount of time (also, e.g., after one minute, two minutes, four minutes, five minutes, 10 minutes, or some other predetermined time interval, the illumination change from suitable to unsuitable), and interface-connected indicator 61b is illuminated as unsuitable when one or more sensors 29b detect that a reliable connection has not been established. Also, for example, when third input device 64b is activated, chassis-legs-locked indicator 58b is illuminated as suitable when chassis legs 73b are closed or locked in position to increase the stability of system 10b. For most or all other configurations of system 10b when third input device 64b is activated, one or more indicators 52b, 54b, 56b, 58b, 59b, 61b, and/or 63b is illuminated to indicate an unsuitable configuration (e.g., reflecting the generally more demanding parameters associated with a relatively weak or frail patient), and light unit 40 also be illuminated to similarly indicate an unsuitable configuration. Also, for example, battery-status indicator 63b is illuminated to indicate an unsuitable configuration when a battery or power source of system 10b is low and illuminate as suitable when a battery or power source of system 10b has sufficient reserve power. In tandem with indicators 52b, 54b, 56b, 58b, 59b, 61b, and/or 63b being illuminated, light unit 40 also be illuminated to provide a consistent notification to attending personnel based on the illumination of the indicators (e.g., light unit 40 disposed on any portion of indicator device 30b is illuminated to provide notification to attending personnel located a significant distance away from system 10b).

The exemplary disclosed device and system provide an indicator device 30 that can be positioned in various locations on a system 10, for example suitably within view of attending personnel such as medical personnel or caretakers who are not in immediate or close vicinity of the system. The exemplary disclosed device and system also provide a setting function that gives an indication of suitability (e.g., based on user attributes such as, for example, patient health) when one or more of the features of system 10 is in a deactivated condition (e.g., when one or more side rails 18 or side rails 20 is lowered to enable the patient to get into or off system 10 unaided, or when a frame 16 is in a lowered or lowermost position). Also for example, system 10 provide an integrated notification system that provides individual monitoring of various parameters as well as monitoring and indication of an overall system status.

It is contemplated that any number or combination of appropriate system features is provided in conjunction with exemplary disclosed system 10, depending on a functionality of various exemplary embodiments of system 10. For example, system 10 have a plurality of configurations suitable for various types or categories of patients.

It is contemplated that the above-disclosed exemplary features is combined with one another in any suitable manner. It will be apparent to those skilled in the art that various modifications and variations can be made to the disclosed method and apparatus. Other embodiments will be apparent to those skilled in the art from consideration of the specification and practice of the disclosed method and apparatus. It is intended that the specification and the disclosed examples be considered as exemplary only, with a true scope being indicated by the following claims.
