The present disclosure relates to patient support apparatuses such as patient beds and particularly, to patient support apparatuses that have therapy devices. More particularly, the present disclosure relates to patient support apparatuses that have integrated limb compression devices.
Patient support apparatuses, such as patient beds, are used in patient rooms to support sick patients and to support patients recovering from surgery, for example. It is desirable for some patients to wear limb compression sleeves, such as foot sleeves, calf sleeves, thigh sleeves, or a combination of these sleeves. The sleeves are inflated and deflated intermittently to promote blood flow within the patient's limb or limbs thereby helping to prevent deep vein thrombosis, for example. Usually, a separate control box which houses the pneumatic components that operate to inflate and deflate the compression sleeve(s) worn by the patient is provided.
Oftentimes, the control box for the compression sleeve(s) is hung on the footboard of the patient bed. Thus, there is a risk that the control box can slip off of the footboard. Also, relatively long power cords are required to be routed from the control box at the foot end of the bed to a power outlet near the head end of the bed or elsewhere in the patient room. The foot ends of patient beds are typically oriented more toward the center of a room and not adjacent to any room wall. The power cord, therefore, may pose a tripping hazard for caregivers, patients, and visitors. The power cord also may be in the way of other carts or wheeled stands, such as those used to support IV pumps and bags, for example. When not in use, the control box must be stored separately within a healthcare facility.
There is an ongoing need to reduce the labor required for caregivers to deliver quality patient care. Further, there is an ongoing need for the cost of healthcare to be reduced. Finally, the comfort of a person in a clinical environment is directly related to their perception of the quality of their care and their recovery. A therapy system that provides patient comfort, reduced cost, and improved caregiver efficiency addresses the aforementioned needs.

The detailed description particularly refers to the accompanying figures in which:
In one embodiment of a therapy system 10, the system 10 includes a patient support apparatus 12 and a pneumatic therapy device 14 configured to couple to the patient support apparatus 12. The patient support apparatus 12, illustratively embodied as a hospital bed 12, includes a patient support structure 21 such as a frame 21 that supports a surface or mattress 22 as shown in
Pneumatic therapy device 14 is illustratively embodied as a sequential compression device assembly (SCD assembly) 14, as shown in
The SCD assemblies 14 disclosed herein are sometimes referred to as limb compression devices, intermittent compression devices (ICDs), DVT prevention systems, or the like. Thus, these terms and variants thereof are used interchangeably herein to cover all types of devices and systems that have compression sleeves with one or more inflatable and deflatable chambers that are controlled pneumatically by delivery and removal of air or other gas from a set of pneumatic components that are contained within patient support apparatus 12.
Referring to
Illustrative patient support apparatus 12 has four siderail assemblies coupled to upper frame assembly 30 as shown in
Upper frame assembly 30 includes a patient support deck 38 that supports mattress 22. Patient support deck 38 is situated over an upper frame 19 of upper frame assembly 30. Mattress 22 includes a head section 40, a seat section 42, a thigh section 43, and a foot section 44 in the illustrative example as shown in
Mattress 22 further includes a pair of edges 61 wherein each of the pair of edges 61 is spaced apart from each other with respective section 40, 42, 43, 44 extending therebetween. In the illustrative embodiment, thigh section 43 and/or foot section 44 is configured to support SCD assembly 14 when independent of the patient as well as when coupled thereto. As will be discussed below, in some embodiments, thigh section 43 and/or foot section 44 may be formed to integrally include SCD assembly 14 and/or be configured to store SCD assembly 14 therein when not in use, when patient is ambulatory, and/or to avoid SCD assembly 14 from contacting a floor of a hospital/care center.
Referring to
As shown diagrammatically in
Main controller 18 is further configured to be in communication with user interface 70. User interface 70 is configured to receive user inputs by the caregiver and/or patient, to communicate such input signals to main controller 18 of patient support apparatus 12 to control the operation of air system 20 and SCD assembly 14 of patient support apparatus 12, and to control the operation of other functions of patient support apparatus 12. User interface 70 is further configured to provide access to air system controller 62 to control operation of SCD assembly 14 from user interface 70. User interface 70 may be formed as a graphical user input (GUI) or display screen 76 coupled to a respective siderail 78 as shown in
As such, main controller 18 is configured to act on information provided by user interface 70 to control air system 20 based on inputs from a user. For example, user interface 70 includes a user input device (not shown) that is indicative of when a user wishes to actuate therapy of SCD assembly 14. The user input device corresponds to sequential compression of SCD assembly 14. Similarly, the user input device provides a signal to main controller 18 that therapy provided by SCD assembly 14 is to be halted when the user input device provides a signal indicative of a user's desire to stop sequential compression of SCD assembly 14. As such, user input devices may signal/indicate that the sequential compression of the respective SCD assembly 14 is to be actuated and/or ceased.
In some embodiments, main controller 18 of patient support apparatus 12 communicates with a caregiver controller/remote computer device 176 via a communication infrastructure 178 such as a wired network of a healthcare facility in which patient support apparatus 12 is located and/or via communications links 177, 179 as shown diagrammatically in
Remote computer 176 may be part of a bed data system, for example. Alternatively or additionally, it is within the scope of this disclosure for circuitry (not shown) of patient support apparatus 12 to communicate with other computers 176 and/or servers such as those included as part of an electronic medical records (EMR) system, a nurse call system, a physician ordering system, an admission/discharge/transfer (ADT) system, or some other system used in a healthcare facility in other embodiments, although this need not be the case.
In the illustrative embodiment, patient support apparatus 12 has a communication interface which provides bidirectional communication via link 177 with infrastructure 178 which, in turn, communicates bidirectionally with computers 176, 181 via links 179, 183 respectively as shown in
Still referring to
As shown in
It should be understood that
As discussed above, main controller 18 includes a processor 72 and a memory device 74 that stores instructions used by processor 72 as shown in
Further, memory device 74 may be pre-programmed to alert the caregiver upon exceeding a predetermined threshold so to avoid patient discomfort, pressure necrosis, and/or loss of capillary integrity leading to edema and increased compartmental pressures. To explain, memory device 74 may be configured to alert the caregiver of a pressure of SCD assembly 14 which exceeds a predetermined threshold pre-programmed therein.
Such a predetermined threshold of pressure may be based on the patient's vitals, medical history, desired outcome of pneumatic therapy (i.e.: sequential compression therapy via SCD assembly 14), as well as other data measurements by sensors 64. Therefore, it is desirable to identify the sequential compression threshold of each patient and avoid reaching such a threshold to avoid patient discomfort, pressure necrosis, and other associated complications.
As mentioned previously, the operation of SCD assembly 14 is controlled by main controller 18 in communication with air system 20. Main controller 18 is configured to communicate with an air source 58, 258 and a respective distribution manifold/outlet 60, 260. While only air source 58 is shown in
In other embodiments, as shown in
In other embodiments of patient support apparatus 12, as shown in
In other embodiments of patient support apparatus 12, as shown in
In some embodiments, the air system 320 further includes a plurality of tubes shown in phantom (not shown) extending between the housing 340 and a port coupled to the frame of the patient support apparatus 12. The plurality of tubes cooperate to guide the pressurized air stream from source of pressurized air from the patient support apparatus 12 to the air system 320. In such an embodiment, the air system 320 does not have an independent source of pressurized air, but receives pressurized air from the patient support apparatus 12 and controls the operation of the sleeves 108. In some embodiments, the air system 320 may be independent of the main controller 18 of the patient support apparatus 12. In other embodiments, the air system 320 may be in electrical communication with the main controller 18 and cooperate with the user interface 76 to allow control of the air system 320 from the user interface 76. The detection of SCD assembly 14 may be accomplished by an at least one pressure/attachment sensor 64 configured to identify attachment of SCD assembly 14 to port 15.
Source of pressurized air 58, 258 is in communication with main controller 18 and air system controller 62 and coupled to distribution manifold 60, 260 as shown in
In the embodiments shown in
As shown in
Distribution manifold 60, 260, 360 (not shown) is operable to close the plurality of valves 63 to maintain the pressure in SCD assembly 14. Illustratively, valves 63 are embodied as solenoid valves. Manifold 60, 260 may also selectively control venting of the SCD assembly 14 to an exhaust (not shown). Illustratively, distribution manifold 60, 260 guides pressurized air stream towards port 15. Port 15 is configured to couple to a single SCD assembly/therapy module 14 such that each port 15 is configured to couple to multiple SCD assemblies 14/therapy modules 14. Illustratively, each port 15 is configured to couple to two SCD assemblies 14 such that each port 15 is configured to operate independently of the other. In some embodiments, additional ports 15 are formed in patient support apparatus 12 and configured to couple to additional SCD assemblies and/or other therapy devices 14. Distribution manifold 60, 260 is in communication with air system controller 62 and configured to operate in response to commands from air system controller 62 and/or main controller 18.
As such, upon receiving an input from user interface 70, main controller 18 communicates the appropriate signal(s) to air system controller 62 to control air system 20. Therefore, when a function is requested by main controller 18, air system controller 62 is configured to energize the appropriate valve of manifold 60, 260 and set the appropriate pulse width modulation for source of pressurized air 58, 258. Illustratively, ambient, environmental air enters air system 20, 220 through an inlet air filter (not shown). The ambient air travels into source of pressurized air 58 through an inlet orifice (not shown). Source of pressurized air 58, 258 then pushes the pressurized air produced therein through a discharge hose (not shown) into an inlet (not shown) of manifold 60, 260 through manifold 60, 260 and plurality of tubes 27, 227 coupled thereto, and to SCD assembly 14 and/or appropriate bladders positioned within mattress 22, 322.
Illustratively, pressurized air is guided into conduit 110 of SCD assembly 14 through port 15. Conduit 110 guides the pressurized air into compression sleeve 108 via a pneumatic connector 115 formed in an outer surface 141 of sleeve 108. Illustratively, each sleeve 108 is formed to include a pressure tap (not shown) in communication with air system 20. The pressure taps are routed to manifold 60 and coupled to a plurality of pressure sensors 64 through sense lines through air system controller 62 for feedback of pressure levels within SCD assembly 14. For example, if pressure in sleeve(s) 108 exceeds a threshold pre-programmed in main controller 18, pressure sensors 64 sense the sleeve(s)′ 108 pressure, provide feedback to main controller 18, and the main controller 18 communicates with air system controller 62 to adjust the pressure of sleeve(s) 108 accordingly. The aforementioned system is closed-loop and feedback dependent.
Illustratively, sensors of sensor block 89, such as, for example, Hall-effect sensors, RFID sensors, near field communication (NFC) sensors, pressure sensors, or the like, are configured to sense tokens (e.g., magnets, RFID tags, NFC tags, etc.). Illustratively, the type/style of sleeve 108 is sensed by sensors 89 and communicated to main controller 18 which, in turn, communicates the sleeve 108 type information to the circuitry for ultimate display on GUI 76 in connection with the compression device control screens. Illustratively, pressure sensors 64 are configured to identify the presence and absence of conduit 110 and, in response, automatically begin, halt, or adjust therapy, respectively, which is discussed in further detail below.
The aforementioned sensed pressure corresponds to the output of source for pressurized air 58, 258. As such, air system controller 62 is configured to regulate the speed of source of pressurized air 58, 258 in correlation to pressure. For example, if a pre-programmed threshold requires a particular discharge from source of pressurized air 58, 258 for function of SCD assembly 14, then main controller 18 is configured to communicate to air system controller 62 so that the appropriate pulse width modulation settings are fixed so to establish the correct pressure and flow output from source of pressurized air 58, 258.
Air system controller 62 includes a processor 100 and a memory device 102 which stores instructions used by processor 100 as shown in
As discussed above, SCD assembly 14 is configured to provide sequential compression therapy to a patient positioned on patient support apparatus 12 as shown in
As such, sleeves 108 are configured to adjust the amount of compression applied to the patient in response to instructions from main controller 18 and/or air system controller 62. Specifically, sleeves 108 are configured to respond to user inputs including, for example, the target pressure to which each sleeve 108 is to be inflated by air system 20 and/or the desired zone(s) (i.e.: foot zone, calf zone, thigh zone, or some combination thereof) of each sleeve 108 to be inflated by air system 20 if sleeve 108 has multiple zones. The selectable therapy settings further include, for example, the frequency of compression, the duty cycle of the compression cycles, the number of cycles, the time period over which the compression therapy is to take place, or some combination thereof. In some embodiments, the selectable therapy settings include selection of pressure versus time curves (e.g., step up and/or step down curves, ramp up and/or ramp down curves, saw tooth curves, and the like) as well as the parameters for the various types of curves (e.g., pressure setting at each step, duration of each step, duration of ramp up, duration of ramp down, and the like).
Looking to
As shown in
Illustratively, main controller 18 is further operable to determine the presence of conduit 110 at port 15. Port 15 is thereby accessible by a caregiver when the patient is positioned on the mattress 22 and configured to couple to multiple SCD assemblies 14. Illustratively, a plurality of SCD assemblies 14 may be removeably coupled to port 15. Further, in embodiments having a plurality of ports 15, each port 15 is configured to couple to SCD assemblies 14 independent of a second port 15. Further, each of the plurality of ports 15, are similarly configured. Additionally, and as discussed above, upon identifying the presence of conduit 110 removeably coupled to port 15, main controller 18 is configured to initiate sequential compression therapy upon identifying the removal of conduit 110 from port 15.
A caregiver may also initiate/terminate therapy by using user interface 70 and inputting the desired action. As such, a particular zone/combination of zone and sleeves 108 may be selected by the caregiver using user interface 70 via user inputs 13. For example, buttons 13 for selection by a user of left and/or right foot sleeves, left and/or right calf sleeves, left and/or right thigh sleeves, or left and/or right combination sleeves such as those described above appear on display screen 76, in some embodiments. It should be appreciated that the compression sleeve 108 on a patient's left leg may be of a different type than that on the patient's right leg. Alternatively or additionally, main controller 18 is operable to determine which type of sleeve 108 is connected to each port 15 based on the time it takes to inflate the particular sleeve 108 to a target pressure as measured by pressure sensors 64. After main controller 18 makes the sleeve type determination for the one or more sleeves 108 coupled to port(s) 15, such information is displayed on GUI 76.
Main controller 18 is illustratively configured to automatically communicate to air system controller 62 to stop therapy in response to a signal from sensors 64 conveying a disconnection of conduits 110 and ports 15. Sensors 64 may be in communication with main controller 18 and are configured to convey data concerning conduit 110. Both the removal/presence of conduit 110 may be determined in a single algorithmic step due to the integral relationship of the presence/absence of conduit 110 at port 15. In some embodiments, sensors 64 are configured to determine the removal of conduit 110 from port 15 and signal to air system controller 62 the removal of conduit 110. Air system controller 62 may then stop the creation/conveyance of pressurized air flow to SCD assembly 14, thereby removing main controller 18 from the method of use for the additional embodiment.
In some embodiments, upon main controller receiving the data from sensors 64 identifying the presence of conduit 110 at port 15, main controller communicates with scale system 23 which detects the presence of SCD assembly 14 and zeros the scale to zero pounds. This avoids discrepancies in patient weight due to the weight of SCD assembly 14 and is done automatically such that the caregiver does not have to remember to zero the patient support apparatus 12 before measuring the weight of the patient positioned on bed 1.
In some embodiments, the removal of pneumatic therapy device 14 and the associated data is communicated to the main controller 18. Such associated data may include, but is not limited to, the location of pneumatic therapy source 14. This data may then be conveyed between main controller 18 to a wall unit (not shown) and further communicated between the wall unit and a nurse station (not shown).
As discussed above, when SCD assembly 14 is coupled to air system 20, 220, air system 20, 220 senses the presence of SCD assembly 14 and begins the transmission of power and/or pressurized air between SCD assembly 14 and air system 20, 220. Illustratively, such transmission of pressurized air is conveyed through a wired connection to SCD assembly 14. Whereas the transmission of power may be completed wirelessly, illustratively. In other embodiments, the transmission of power may be conveyed through a wired connection. In some embodiments, air system 20, 220 continuously generates the pressurized air stream upon coupling to SCD assembly 14, thereby causing SCD assembly 14 to maintain a desired level of pressure within SCD assembly 14. In other embodiments, air system 20, 220 is pre-programmed to generate pressurized air in cycles, waves, and/or any other desired patterns. In still other embodiments, main controller 18 and air system 20, 220 are in communication such that air system 20, 220 is configured to move between a plurality of pre-programmed patterns in response to user input or automatically in response to sensed pressure values of SCD assembly 14 exceeding a predetermined threshold. Main controller 18, sensors 64, and air system 20, 220 are in communication and further configured to identify the removal of the SCD assembly 14 and, illustratively, stop production of the pressurized air stream within the air system 20, 220.
Therefore, upon identification of SCD assembly 14 coupling to air system 20, 220, air system 20, 220 communicates such coupling to main controller 18. Main controller 18 is configured to communicate with user interface 70 such that user interface 70 is updated to control operation of SCD assembly 14 by allowing access to air system 20, 220 via user interface 70. Such access allows for a caregiver to input/receive patient data at a centralized location on patient support apparatus 12. Illustratively, user interface 70 is configured to alert the caregiver upon disconnection of SCD assembly 14 and air system 20, 220 and/or other interruptions to the therapy therein provided.
In further embodiments, conduit 110 is formed as a pneumatic conduit and is made of an elastic, non-porous material configured to expand in length when pressurized with air. Such elastic, non-porous material is configured to move between an extended length (not shown) and a storage length (not shown) in response to the presence of pressurized air therein. Storage length has a distance measuring less than a distance of extended length, and, as such, storage length has a surface area measuring less than a surface area of extended length. At rest, pneumatic conduit has the storage length. Upon actuation of source of pressurized air 58, 258, pneumatic conduit reacts to the presence of pressurized air by increasing the length and surface area of pneumatic conduit. As such, so long as the pressurized air is directed into pneumatic conduit, pneumatic conduit will maintain the extended length. Therefore, a production and direction of the majority of the pressurized air into conduit is to be ceased before conduit returns to storage length. This permits conduit to be stored in a variety of manners due to the decreased length and surface area of conduit.
In other embodiments in which conduit 110 is formed as a pneumatic conduit, pneumatic conduit is configured to include a break away coupler (not shown). Break away coupler may be positioned between sleeve 108 and conduit 110 and/or between a first conduit section extending between sleeve 108 and break away coupler and a second conduit section extending between break away coupler and second end of conduit. Break away coupler is configured to disconnect from conduit 110 when longitudinal forces in line with conduit 110 exceed a pre-determined breaking force of coupler. The force needed to decouple coupler and conduit 110 is substantially greater than the longitudinal force created by the pressurized air within conduit 110 during operation of SCD assembly 14 and/or other therapies. As such, actuation of SCD assembly 14 does not cause coupler to break away from conduit 110 unless such force exceeds the breaking force of coupler. Further, the breaking force is substantially less than the force exerted upon conduit 110 by a leg of the patient when conduit 110 creates a fall risk. Break away coupler, therefore, is configured to break away from conduit 110 in response to the patient tripping over conduit 110, thereby resulting in a cessation of therapy until coupler is reattached to conduit 110. As such, upon main controller 18 ceasing production of pressurized air and the caregiver removal of SCD assembly 14 and SCD assembly 14 is decoupled from port 15.
