Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority under 35 U.S.C. §119(e) to U.S. Provisional Application No. 63 / 403,116, filed on September 1, 2022, which is expressly incorporated herein by reference. Background Art

[0003] The present invention relates to determining the hierarchy of patient care protocols to be implemented, for example using sensors of a patient support device such as a hospital bed. More specifically, the present invention relates to a system or method for communicating a treatment protocol and determining whether a patient support device should issue an alert.

[0004] Patient support devices (including mattresses, stretchers, operating room tables, etc.) are commonly used in various care environments to facilitate patient care and transportation. Patient support devices are programmed with protocols to enable users to perform various automated functions related to patient support. Examples of such automated functions include raising or lowering one or more sections of a patient support, adjusting the configuration of a bed frame or support surface or a portion thereof, and activating or deactivating selected treatments, alarms, communications, and other automated features of a patient support.

[0005] Many such patient supports include a frame, a platform supported by the frame, a mattress, a bed rail configured to prevent the patient from getting out of the mattress, and a controller configured to control one or more features of the bed. The patient, caregiver, or visitor may intermittently change the position of one or more components of the patient support device during the day. In some cases, it is important to determine the position of one or more components relative to the patient support device before implementing a treatment operation protocol. In addition, sensors can be used to determine the position of one or more components.

[0006] Monitoring various components of a patient support device may include monitoring position, angle, movement, or other attributes. A caregiver may not be able to determine whether different components are in compliance with a therapeutic operating protocol. The ability of a patient support device to automatically determine compliance may prevent potential harm to the patient. Thus, characterizing components of a patient support device in accordance with any therapeutic operating protocol communicated to a caregiver may provide improved care for the patient.

[0041] exist Figure 1 An illustrative patient support apparatus 10 embodied as a hospital bed is shown in FIG. Figure 1The bed 10 has a frame 20 including a base frame 22 supported on casters 24. The fixed base frame 22 further supports a gravity frame 30, and an adjustably positionable mattress support upper frame 34 further supports a mattress 18. The bed 10 also includes a headboard 12 located at a head end 46 of the bed 10, a footboard 16 located at a foot end 48 of the bed 10, and movable bedrails 14A-D coupled to the upper frame 34 of the bed 10. The bed 10 also includes a user interface 54 located on one of the bedrails 14A-D. Figure 1 The bed 10 of the embodiment of FIG. 1 is generally configured to adjustably position the upper frame 34 relative to the base 22 to adjust the position of a patient supported on the mattress 18 .

[0042] Conventional structures and devices may be provided to adjustably position the upper frame 34, and such conventional structures and devices may include, for example, linkages, actuators, and other moving components and devices coupled between the base 22 and the gravity frame 30 and / or between the gravity frame 30 and the upper frame 34. The position of the upper frame 34 and the mattress 18 relative to the base 22 or the gravity frame 30 is controlled, for example, by the patient control pendant 56 or the user interface 54. For example, the upper frame 34 may be adjustably positioned to be generally tilted from the head end 46 to the foot end 48, or vice versa. In addition, the upper frame 34 may be adjustably positioned so that the head section 44 of the mattress 18 is positioned between a minimum and maximum tilt angle (e.g., 0-65 degrees) relative to the horizontal or the bed board, and the upper frame 34 may also be adjustably positioned so that the seat portion (not shown) of the mattress 18 is positioned at a maximum {HRBTL-23012-CNPT / 02161386v1}-5-

[0043] Those skilled in the art will recognize that the upper frame 34 or portions thereof may be adjustably positioned in other orientations, and the present invention also contemplates such other orientations.

[0044] One or more components of the patient support device may be communicated by an icon 32 projected on the floor and / or an icon 33 illuminated on a frame member of the bed 10. Examples of structures for projecting icons 32 on the floor or illuminating icons 33 on the frame are disclosed in WO2016196403A1 and US20180184984A1 (each of which is incorporated herein by reference to disclose structures for projecting icons on the floor). The projected icon 32 may be used to indicate whether a component of the patient support device 10 complies with a baseline operating protocol used by the patient. In some embodiments, the bed rail status of the patient support device 10 may be communicated by an icon 32 projected on the floor. The projected icon 32 may be used to indicate whether the bed rails 14A-D of the patient support device 10 comply with a baseline operating protocol. The therapeutic operating protocol may be programmed into the user interface 54 by a caregiver or user.

[0045] For example, the treatment operation protocol may be a CLR (Continuous Lateral Rotation) protocol that requires all four bed rails 14A-D to be raised before the CLR begins. Currently, caregivers face significant challenges in caring for patients with pulmonary therapy on a patient platform. Many of these treatments include patient rotation. Rotational therapy typically includes lateral rotation of the patient support device 10 for patients requiring pulmonary therapy or bedsore prevention or treatment. The rotatable support surface typically includes a mattress 18 on the bed 10 that is rotated laterally by an air support system when all bed rails 14A-D are in the upward position. As shown in FIG. Figure 2 As shown, the projected icon 32 may not indicate a warning even though the patient support device 10 is not in compliance with the treatment operating protocol but is in compliance with the baseline operating protocol. Although the bed rail 14A is lowered, the projected icon 32 is a green flag indicating compliance. This effect may exist due to the different requirements of the two protocols used simultaneously (the baseline protocol that defines the nominal bed condition and the treatment protocol that is selectively applied only when treatment is being performed). The present invention solves the management of inconsistent requirements of the protocols that are active simultaneously.

[0046] exist Figure 3 In one illustrative embodiment, shown diagrammatically in FIG. 1 , the bed 10 has a control system 26 that includes a controller 28, a scale module 50, component modules (e.g., a bedrail module 52), and a user interface 54. The bed 10 can communicate with the hospital information system 36 via a communication infrastructure 110. The scale module 50 of the bed 10 is used to measure the motion of a patient occupying the bed 10 by measuring signals from load sensors 66, 68, 70, 72. The bedrail module 52 of the bed 10 is used to determine the operation of the bedrails 14A-D by measuring signals from sensors 82, 84, 86, 88.

[0047] In the illustrated embodiment, the controller 28, the scale module 50, the component module (eg, the bed rail module 52) {HRBTL-23012-CNPT / 02161386v1}-6-

[0048] Each of the controller 28, the scale module 50, the bedrail module 52, and the user interface 54 includes a processor 62 and a storage device 64. The processor 62 and the storage device 64 are used in the controller 28, the scale module 50, the bedrail module 52, and the user interface 54. The storage device 64 includes instructions that, when executed by the processor 62, cause the processor 62 to perform functions associated with a particular one of the controller 28, the scale module 50, the bedrail module 52, and the user interface 54.

[0049] In some embodiments, the treatment protocol may require changing the position of more than one component of the bed 10 (e.g., bed rails 14A-D, head end 48, etc.). For example, the treatment protocol may require all bed rails 14A-D to be in a specific position, or require the head end 46 to be at a specific angle. Figure 4 As shown, in step 112, the controller 28 is operable to act as a protocol conflict manager to execute a decision tree to determine whether the user interface 54 has been programmed with a therapeutic operating protocol. If the user interface 54 has been programmed with a therapeutic operating protocol, then in step 116, the therapeutic operating protocol will replace the baseline operating protocol. Then, in step 118, the controller 28 is operable to identify components of the bed 10 (e.g., bedrails 14A-D, head end 48, etc.) that require a different orientation in the therapeutic operating protocol than in the baseline operating protocol. Then, in step 120, the controller 28 is operable to communicate with sensors (e.g., sensors 82, 84, 86, 88) in the identified component modules of the bed 10 (e.g., bedrail module 52) to determine whether they comply with the therapeutic operating protocol.

[0050] If it is determined in step 122 that the components of the bed 10 (e.g., bedrails 14A-D, head end 48, etc.) comply with the therapeutic operating protocol, then no warning or alert is issued in step 124. If it is determined in step 122 that the components of the bed 10 (e.g., bedrails 14A-D, head end 48, etc.) do not comply with the therapeutic operating protocol, then a warning or alert is issued in step 126. If the controller 28 determines in step 112 that the user interface 54 has not been programmed with the therapeutic operating protocol, then in step 114 the controller 28 is operable to determine whether the components of the bed 10 (e.g., bedrails 14A-D, head end 48, etc.) comply with the baseline operating protocol. If it is determined in step 114 that the components of the bed 10 (e.g., bedrails 14A-D, head end 48, etc.) comply with the baseline operating protocol, then no warning or alert is issued in step 124. If it is determined in step 114 that the components of the bed 10 (e.g., bedrails 14A-D, head end 48, etc.) do not comply with the baseline operating protocol, then a warning or alert is issued in step 126.

[0051] The components of the control system 26 communicate with each other to share information and distribute the functions of the bed 10. The processor 62 of each of the controller 28, the scale module 50, the component modules (e.g., the bed rail module 52), and the user interface 54 can also operate based on instructions from the storage device 64 to communicate with the controller 28, the scale module 50, the component modules (e.g., the bed rail module 52), and other modules in the user interface 54 using the communication protocol. It should be understood that the term processor herein includes any microprocessor, microcontroller, processor circuit, control circuit, pre-programmed device or capable of accessing a storage device and executing non-transient instructions to perform any of the inventions herein {HRBTL-23012-CNPT / 02161386v1}-7-

[0052] In the illustrated embodiment, the control system 26 uses a conventional controller area network (CAN) for communication between subsystems, but it should be understood that any of a variety of networking and communication solution protocols may be used in the control system 26.

[0053] Return to reference Figure 3 , bedrail module 52 is a functional controller of bedrails 14A-D and includes a processor 62 and a storage device 64. Processor 62 communicates with bedrails 14A-D. Sensor assembly 60 includes separate sensors for determining the position of each of bedrails 14A-D. Signals from sensors 82, 84, 86, and 88 are used to determine the position of bedrails 14A-D and make inferences regarding compliance with any patient bedrail protocols that a user may have entered on patient interface 54. Such determinations will improve patient safety and provide a more adequate and accurate analysis of the patient's condition related to the patient support device. In addition, bed 10 can record the existence of a therapeutic operating protocol and send the data to an electronic medical record. As Figure 2 As shown, the treatment protocol may be indicated on the user interface 54. The display screen 94 may include a status panel 98 that indicates whether treatment has been stopped due to non-compliance with the treatment protocol. The status panel 98 may include additional information.

[0054] The display screen 94 of the user interface 54 may include more than one input icon. Figure 5As shown, the home screen 132 on the display screen 94 includes a home icon 134, a move up icon 136, a balance icon 138, a physiological icon 140, and a settings icon 142. When any of the icons are activated, the controller 28 receives user input commands from the graphic display screen 94. Based on the user input commands on the display 94 and the data processed by the processor 62, the controller 28 controls various functions of the bed 10, such as the pneumatic system and / or raising or lowering different portions of the bed 10. In some embodiments, based on the user input commands on the display 94 and the data processed by the processor 62, the controller 28 controls the functions of one or more actuators in the bed 10. In some embodiments, based on the user input commands on the display 94 and the data processed by the processor 62, the controller 28 controls the functions of the bedrails 14A-D.

[0055] like Figure 6 As shown, when the caregiver activates the settings icon 142, the controller 28 prompts the caregiver to select bed features on the features screen 146. Figure 7 As shown, the caregiver can activate the bed rail protocol icon 144 (in Figure 6 14A-D) to cause the controller 28 to call up the current bedrail protocols screen 148. The current bedrail protocols screen 148 of the user interface 54 may list different treatment operation protocols that require certain bedrail 14A-D positions, including the CLR protocol. The current bedrail protocols screen 148 includes a CLR protocol information icon 152 that the caregiver may activate to cause the controller 28 to display a Figure 8 Information about the CLR protocol is shown on the information screen 156 in FIG. Selecting the "Yes" icon 158 on the information screen 156 activates the CLR protocol. Fig. 9 , when the caregiver activates the "Yes" icon 158 on the information screen 156, the CLR {HRBTL-23012-CNPT / 02161386v1}-8-

[0056] The protocol icon 150 is selected. The controller 28 is operable to identify the CLR protocol as the therapeutic operating protocol to replace any baseline operating protocol. The caregiver may activate the "Accept" icon on the current bedrail protocol screen 148 to confirm the selection of the CLR protocol.

[0057] Fig.10 The figure shows that if the controller 28 is operable to determine a therapeutic operating protocol in lieu of a baseline operating protocol, the projected icon 32 may indicate a bedrail status indicating that the bed 10 does not comply with the therapeutic operating protocol. Fig.10 In FIG. 1 , since 14A is lowered, the projected icon 32 does not indicate compliance.
