The present disclosure relates generally to wireless control systems for patient-support apparatuses, such as hospital beds. More particularly, the present disclosure relates to wireless control systems having a wireless controller usable by a patient or other person to control functions of the patient-support apparatus and/or other hospital room equipment.
Typical hospital beds have a number of patient input devices, such as buttons, for controlling functions of the bed and other hospital room equipment such as entertainment devices, environment control devices, and/or a nurse call system. The patient input devices are typically located on one or more siderails of the bed. However, some patients may have difficulty in identifying and/or accessing the patient input devices that are located on the siderails of the bed. For example, a patient may have difficulty accessing the patient input devices from a resting position on the bed. Additionally, the patient may have difficulty accessing and/or identifying the patient input devices such as when the patient is standing next to the bed or sitting in a nearby chair. Some hospital beds may include a wired or otherwise tethered pendant or controller having a selection of patient input devices located thereon. However, the wires of the pendant may become entangled with other lines, such as IV lines, patient monitoring lines, catheter lines, nasogastric lines, and the like.

The controller 12 is usable by a patient to wirelessly control functions of the apparatus 14. For example, a patient may use the controller 12 to articulate sections of the apparatus 14 such as elevating a head section of the apparatus 14, turn on/off lights associated with the apparatus 14, or any other function of the apparatus 14 typically controllable by a patient (for example, via a patient input button located on the apparatus 14).
In some embodiments, the controller 12 is also configured to wirelessly control functions of hospital room equipment 18. For example, the controller 12 may be configured to wirelessly control functions of environment control devices 20 such as room lights and/or thermostats, entertainment devices 22 such as televisions and/or radios, a nurse calls system 24, or any other equipment located in or associated with a hospital room including any equipment commonly controllable via patient input buttons located on the apparatus 14. Such functions may include on/off, volume up/down, silent on/off, nurse call, and/or any other function based on the particular type of hospital room equipment 18. Additionally, the equipment 18 may include a network (not shown) such as a local area network (LAN), a wide area network (WAN), or any other type of network. The system 24 may form a portion of the network or may otherwise be coupled to the network.
In some embodiments, the controller 12 is configured to control the hospital room equipment 18 by wirelessly communicating one or more control signals to the apparatus 14. In response, the apparatus 14 is configured to relay or otherwise communicate control signals to the equipment 18 based on the controls signals received from the controller 12. The apparatus 14 may communicate the control signals via wired or wireless communication. For example, as illustrated in
In an alternative embodiment, the controller 12 may be configured to communicate directly with one or more of the hospital room equipment devices 18. In such embodiments, the controller 12 communicates wirelessly with the hospital room equipment 18 as illustrated in
Referring now to
The control inputs 38, 40, battery 42, and transmitter 44 are coupled to and communicate with the microprocessor 32 via signal paths 48, 50, 52, 54, respectively. The signal paths 48, 50, 52, 54 may be any type of signal paths capable of providing communication between the components including, but not limited to, wires, printed circuit board (PCB) traces, and/or vias. The microprocessor 36 may be embodied as any type of microprocessor including, but not limited to, a general microprocessor, a dedicated microprocessor having software/firmware embedded therein, a microcontroller, a collection of low level devices such as logic gates, or any other type of processing unit(s).
The patient-support control inputs 38 and hospital room equipment control inputs 40 may be embodied as any type of patient input device such as buttons, switches of all types, knobs, dials, touch screens, levers, voice-activated sensors, associated software switches, and the like. Accordingly, as used herein, the term “control input” is intended to mean devices of any and all types that may be interacted with by the patient to provide some sort of signal (e.g., an input or control signal). The patient-support control inputs 38 may include any number of control inputs selectable by the patient to control functions of the apparatus 14. For example, the control inputs 38 may include control inputs for articulating the apparatus 14 such as elevating a head section or a foot section of the apparatus 14. In one specific embodiment, the patient-support control inputs 38 include a number of control inputs corresponding to a number of patient control inputs (not shown) located on the apparatus 14.
Similarly, the hospital room equipment control inputs 40 may include any number of control inputs selectable by the patient to control functions of one or more hospital room equipment devices 18 such as environment control devices 20, entertainment device 22, and/or nurse call system 24. For example, the control inputs 40 may include control inputs for controlling functions of a television or radio such as on/off control, volume adjustment, tuning, and/or silencing. Additionally, the control inputs 40 may include control inputs for controlling functions such as on/off control and/or other adjustments of a hospital room light, nightlight, thermostat, or the like. Further, the control inputs 40 may include control inputs for controlling functions of the nurse call system 24 such as requesting the service of a nurse associated with the patient. It should be understood that the control inputs 38 may include a control input for performing any function of a hospital room equipment device 18 having a receiver configured to receive wireless communications from the controller 12. Additionally, in some embodiments, a single control input 40 may be configurable, e.g. by selecting an equipment selection input (not shown), to control functions of multiple hospital room equipment devices 18. For example, a single control input 40 may be selectable by the patient to control the volume of a television or control the volume of a radio by first selecting the appropriate equipment selection input.
The battery 42 may be any type of battery including an alkaline battery, lithium battery, nickel cadmium battery, or the like. Additionally the battery 42 may be comprised of any number of batteries configured in a series or parallel configuration to provide one of a range of voltage and current capabilities. In one particular embodiment, the battery 42 is a rechargeable battery. The controller 12 may also include charging contacts (not shown) on the outside of the controller 12 for charging the battery 42. In such embodiments, the charging contacts are electrically coupled to the battery 42. Alternatively, the wireless controller 12 may include a rechargeable battery 42 but not include charging contacts. In such embodiments, the battery 42 may be charged by alternative charging methods that do not require physical connection to the battery (e.g., inductive charging).
The transmitter may be any type of transmitter including an RF or IR transmitter. The transmitter 44 and microprocessor 36 may be configured to use any type of wireless communication protocol including Bluetooth, Zigbee, Wireless Fidelity (WiFi), one or more of the Infrared Data Association's (IrDA) protocol, or any other type of RF and/or IR communication protocol. In one embodiment, the transmitter 44 is configured to wirelessly communicate with the apparatus 14 and with one or more hospital room equipment devices 18 via wireless communication signals 56. However, in a particular alternative embodiment, the transmitter 44 may be configured to communicate only with the apparatus 14. In such embodiments, the transmitter 44 may be a short range transmitter having a communication range of about twenty-four inches or less. Such a short range transmitter communicates with the apparatus 14 only within the short communication range. A controller 12 having a short range transmitter reduces the possibility that the patient may inadvertently control the wrong patient-support apparatus or inadvertently control more than one patient-support apparatus at a time. In embodiments in which the transmitter 44 is a short range transmitter, the controller 12 may also include a separate long range transmitter 60 for communicating with one or more hospital room equipment devices 18 via wireless communication signals 58. The transmitter 60 is electrically coupled to the microprocessor 36 via a signal path 62 such as a number of wires, PCB traces, or vias. The transmitter 60 may be configured to communicate with a single equipment device 18 or a number of equipment devices 18.
In an alternative embodiment, the controller 12 is programmable to communicate with only a single designated apparatus 14. In such embodiments, the transmitter 44 may or may not be a short range transmitter. The controller 12 may include one or more programming input devices (not shown), such as a programming button, for programming the controller 12 to the designated apparatus 14. Additionally, the controller 12 may include a visual indicator such as an LED to visually indicate that the controller 12 has been programmed to the designated apparatus 14. While so programmed, the controller 12 is operable to control only the designated apparatus 14 to the exclusion of other patient-support apparatuses located nearby. To reduce the possibility that the patient 66 or other person inadvertently re-programs the controller 12 to another apparatus 14, the programming input device may be operable only within a predetermined programming range of the apparatus 14. In one particular embodiment, the programming range is about six inches or less. While the controller 12 is within the programming range, the programming input device may be selected by a patient or caregiver to program or otherwise associate the controller 12 with the apparatus 14 used by the patient. Accordingly, the controller 12 and/or the apparatus 14 may include additional circuitry and other devices for determining if the controller 12 is within the programming range. For example, the controller 12 may include an additional transmitter having a communication range less than the transmitter 44. Alternatively, the apparatus 14 may include circuitry to determine if the controller 12 is within the programming range based on one or more data criteria such as signal strength.
The controller 12 may also include a programming input device for programming the controller 12 to one or more of the hospital room equipment devices 18. For example, the controller 12 may include a television programming button selectable by the patient or caregiver to program the controller 12 to the particular type, brand, and/or model of television, radio, or other entertainment and/or environment control device located in the hospital room. Accordingly, a hospital may retain a number of controllers 12, each controller 12 being programmable to control any one of a number of apparatuses 14 and any number of hospital room equipment devices 18.
In an additional alternative embodiment, the controller 12 may be configured to communicate with the apparatus 14 only while operated by a designated patient associated with the apparatus 14. For example, as illustrated in
Referring back to

The receiver(s) 68, the patient identification module 72, and the bed articulation system 74 are electrically coupled to and communicate with the bed control system 70 via signal paths 76, 78, and 80, respectively. Although the signal paths 76, 78, 80 are illustrated as single interconnects, the paths 76, 78, 80 may include any number of interconnects. Additionally, the signal paths 76, 78, 80 may be embodied as any type of signal path including, but not limited to, wires, PCB traces, and wireless connections.
The bed control system 70 includes electronics, communication networks, and other devices for controlling functions of the apparatus 14 and for communicating with the receiver(s) 68, the module 72, and the system 74. The patient identification module 72 includes electronics, communication networks, and other devices configured to identify the patient associated with the apparatus 14 (e.g., the patient resting on the apparatus 14). The patient identification module 72 may identify the patient via any one of a number of patient identification technologies including, but not limited to, radio frequency identification (RFID), barcode scanning, electromagnetic identification, and the like. For example, the module 72 may include a RFID reader configured to interrogate or otherwise communicate with the patient identification wristband 64 worn by a patient and to determine the identify of the patient based thereon. The bed articulation system 74 includes electrical and mechanical components to facilitate the articulation functionality of the apparatus 14. For example the system 74 may include drive circuits, electro-mechanical actuators, hydraulic cylinders, electric motors, associated gears such as lead screws and worm gears, and linkages, as well as combinations of these elements.
The apparatus 14 includes a wireless hand-held controller or pendent docking station 82. However, in other embodiments, the apparatus 14 may not include any or may include any number of docking stations 82. The docking station 82 is configured to receive the controller 12. The patient 66 may position the controller 12 in the docking station 82 when the controller 12 is not in use by the patient 66. In some embodiments, the docking station 82 is configured to charge the controller 12 while the controller 12 is positioned in or otherwise received by the docking station 82. If the controller 12 includes charging contacts, the docking station 82 may include corresponding charging contacts positioned to contact the charging contacts of the controller 12 while controller 12 is positioned in the docking station 82. In an alterative embodiments, the docking station 82 is configured to inductively charge the controller 12 while the controller 12 is received by the station 82. In such embodiments, the docking station 82 may or may not include charging contacts. The wireless control system 10 may also include any number of other docking stations 84 located apart from the apparatus 14. For example, the wireless control system 10 may include a docking station 84 located at a nurse call center for charging a number of controllers 12 stored at the nurse call center.
Referring now to
The patient-support deck 88 is controllably movable to one of a number of positions via the bed articulation system 74. For example, a head section 100 of the deck 88 may be inclined to elevate the upper body of a patient 66 resting on the mattress 90. Alternately, a foot section 102 of the deck 88 may be inclined to elevate the lower body of the patient 66. Additionally, the deck 88 may be movable to a Trendelenberg or reverse-Trendelenberg position.
The mattress 90 may be any type of mattress commonly used in patient-support apparatuses. For example, the mattress may be a spring mattress, air mattress, foam mattress, or any other type of mattress. Additionally, the mattress 90, deck 88, and/or frame 86 may include sensors and/or other electrical devices for monitoring the mattress 90 and/or the patient. The mattress 90 is positioned on deck 88 and supports the patient 66 resting thereon.
Each of the siderails 92, 94 is coupled to the frame 88 via a siderail support 104 which is configured to permit movement of the siderails 92, 94 between a raised position and a lowered position. The siderails 92, 94 may be moved to the lowered position to allow the patient 66 to exit the apparatus 14 or to the raised position when the patient 66 is resting on the apparatus 14 to protect the patient 66 from exiting the apparatus 14 undesirably.
As described above in regard to
In other embodiments, the apparatus 14 may include any number of receivers 68 positioned in any location on the apparatus 14 that is wirelessly accessibly by the patient 66. Further, as illustrated in
