Description

BACKGROUND

The present disclosure relates to features of patient support apparatuses such as hospital beds. In one aspect, the present disclosure relates to patient control arms having user inputs that a patient uses to control features and functions of hospital beds, as well as other features and functions. In another aspect, the present disclosure relates to user inputs for locking out the ability to use one or more controls or features of a patient support apparatus.

Handheld personal phones, aka smartphones, are owned by a large percentage of the population. Many owners of these phones often believe they could not function adequately without them. Patients in healthcare facilities prefer to have their phones accessible while admitted to a healthcare facility. However, current patient support apparatuses on the market today do not adequately address patients' desire for ease of use of their smartphones while confined to a patient support apparatus. Some patient's and caregivers may wish to interact with one another via the patient's phone. Other aspects of a patient's care while in a healthcare facility may be enhanced if a patient has access to their phone. Allowing patients better ergonomic use of their personal phones while confined to a hospital bed, for example, may improve their experience while in a hospital or other healthcare facility.

It is sometimes desirable for a patient to be supported in a patient support apparatus, such as a hospital bed, with a head section of a mattress support deck of the bed elevated above a threshold angle. The Joint Committee on Accreditation of Healthcare Organizations (JCAHO) recommends that, under some circumstances, a patient be supported on a hospital bed in a semi-recumbent position, instead of a supine position, to reduce the risk of Ventilator-Associated Pneumonia (VAP) occurrence. JCAHO recommends head-of-bed angle (HOBA) for mechanically ventilated patients of at least 45 degrees in order to prevent pneumonia. For patients at high risk of skin breakdown, a HOBA of at least 30 degrees is recommended in order to prevent pneumonia and the development of pressure ulcers. See U.S. Pat. No. 7,487,562 in this regard.

Some existing hospital beds have an alarm that sounds and/or that is sent as an alarm signal to a remote computer device, such as a nurse call computer, if the head section of the bed is lowered below the threshold angle while a HOBA monitoring system has been armed or enabled. This type of prior art bed is described in the '562 patent mentioned above. Minimizing the number of alarms in a healthcare facility to which caregivers must respond, including head of bed angle alarms, may increase caregiver productivity.

SUMMARY

An apparatus, system, or method may comprise one or more of the features recited in the appended claims and/or the following features which, alone or in any combination, may comprise patentable subject matter:

A patient control unit for controlling functions of a hospital bed may be provided.

DETAILED DESCRIPTION

A patient support apparatus, such as illustrative hospital bed 10, includes a frame 12 that, in turn, includes a base frame 14, an upper frame 16, and a patient support deck 18 as shown in FIG. 1. Deck 18 includes a head section 20, a seat section 22, a thigh section 24, and a foot section 26. Bed 10 has a mattress 28, sometimes referred to in the art as a patient support surface, supported atop sections 20, 22, 24, 26. One or more of sections 20, 22, 24, 26 are selectively movable relative to upper frame 16 to support a patient in a variety of positions. Bed 10 includes various actuators (not shown) that move the movable sections 20, 22, 24, 26 and that raise, lower, and tilt upper frame 16 relative to base frame 14 as is well known in the art. Examples of beds having such actuators are shown and described in U.S. Pat. Nos. 7,296,312 and 5,715,548, each of which is hereby expressly incorporated by referenced herein to the extent not inconsistent with the present disclosure which shall control as to any inconsistencies.

Bed 10 also has four casters 30 (only two of which can be seen in FIG. 1) and a pair of butterfly brake pedals 32 (only one of which can be seen in FIG. 1) which are used to brake and release casters 30 via a braking linkage or other similar mechanism as is known in the art. Another foot pedal assembly 34 is provided on the base frame 14 of illustrative bed 10 for raising and lowering one portion of the bed relative to another, also in a well-known manner. A pair of push handles 36 are provided at a head end 38 of bed 10 and are used by caregivers to push bed 10 from one location to another when casters 30 are unbraked or released.

Bed 10 has a footboard 40 coupled to foot deck section 18 at a foot end 42 of bed 10. In the illustrative example, a caregiver control pod 44 extends upwardly from a central region of a top bar 46 of footboard 40. Caregiver controls, in the form of user inputs such as one or more of buttons, switches, touchscreen displays, and the like are provided on the surface of pod 44 that faces away from mattress 28. Thus, the caregiver controls are generally inaccessible to a patient lying on mattress 28. In some embodiments, the caregiver controls on pod 44 are similar to one or more of the user inputs discussed below in connection with FIGS. 2, 4 and 5. Additional examples of caregiver controls are found in U.S. Patent Application Publication Nos. 2012/0089419 A1, 2012/0073054 A1 and 2008/0235872, each of which is hereby expressly incorporated by referenced herein to the extent not inconsistent with the present disclosure which shall control as to any inconsistencies.

Bed 10 also includes a set of siderails 48a, 48b, 48c, 48d as shown in FIG. 1. In the illustrative example, siderails 48a, 48b are head end siderails (aka “head rails”) and siderails 48c, 48d are foot end siderails (aka “foot rails”). Each of siderails 48a, 48b, 48c, 48d has a hand-receiving recess 50 through which a release handle (not shown) is accessible for releasing a locking mechanism (not shown) so that the respective siderail 48a, 48b, 48c, 48d can be moved from a respective raised position (shown in FIG. 1) to a respective lowered position (not shown). Siderail 48a includes a phone-receiving recess 52 formed therein. Siderail 48c has a first tablet-receiving recess 53 formed in a top rail 55 thereof and a second tablet-receiving recess 54 formed in a main body 56 thereof.

Recess 52 is sized and configured to receive a patient's personal handheld phone 60 (e.g., a smartphone) therein. A retention bar 57 is provided on siderail 48a and bridges across recess 52 to help retain phone 60 therein as shown in FIG. 1. Recesses 53, 54 are sized and configured to receive a patient's personal tablet computer 62 therein. A retention bar 58 is provided on rail 55 of siderail 48c and bridges across recess 53 to help retain an upper region of tablet computer 62 therein and a retention rib 59 extends upwardly from main body 56 of siderail 48c adjacent to recess 54 to help retain a lower region of table computer 62 therein. Recesses 52, 53, 54 are provided in the surfaces of siderails 48a, 48c that face toward mattress 28 and the patient supported thereon. In some embodiments, similar surfaces of siderail 48b, 48d also include similar recesses and the accompanying retention bars and retention rib, but this need not be the case as most patients typically will have only one personal phone and/or one personal tablet computer. However, by providing all of siderails 48a, 48b, 48c, 48d with the illustrative recesses 52, 53, 54, a patient who has the use of only one arm can choose the appropriate side of bed 10 for storage of their respective devices.

Bed 10 also include a patient control unit 70 that includes a generally trapezoidal shaped housing 72 and an arm assembly 74 as shown in FIG. 1. Housing 72 has a generally planar first side 76 (shown best in FIG. 2), a generally planar second side 78 (shown best in FIG. 3A), and perimetral edges including a top edge 80, a first side edge 82, a second side edge 84, and a bottom edge 86 as shown in FIG. 2. Edges 80, 82, 84, 86 interconnect the first and second sides 76, 78 to form the overall shape of housing 72. Arm assembly 74 has a first end 88 coupled to top edge 80 of housing 72 and a second end 90 coupled to head section 20 of frame 12 of bed 10. Arm assembly 74 is sized and configured so as to suspend housing 72 generally above a patient's torso region at a location where the patient can easily grab housing 72 with their hands.

Referring now to FIG. 2, first side 76 of housing 72 of patient control unit has user inputs and various indicia including the following:

Mattress firmer button 92—pressed to signal a pneumatic system of bed 10 to increase the pressure in one or more air bladders of mattress 28;

Mattress softer button 94—pressed to signal the pneumatic system of bed 10 to decrease the pressure in one or more air bladders of mattress 28;

Patient egress button 96—pressed when a patient is egressing from a side of mattress 28 to increase the pressure in one or more seat zone bladders of mattress 28;

Speakers (not shown) are located behind speaker grills 136 in the upper corner regions of first side 76 as shown in FIG. 2. A large aperture 138 in housing 72 defines a hand grip 140 that a patient grasps to reposition housing 72. A central region of upper edge 80 of housing 72 is provided with a raised boss 142 and first end 88 of arm assembly 74 is received within boss 142. Housing 72 is rotatable relative to first end 88 of arm assembly 74 through at least 180 degrees, up to and including about 360 degrees in some embodiments. Thus, the housing 72 is pivotable relative to the arm assembly 74 between a first position in which the first side 76 of the housing is presented to the patient on bed 10 and a second position in which the second side 78 of the housing 74 is presented to the patient on bed 10. A stay-in-bed indicia is provided on boss 142 and is illuminated when a patient position monitoring (PPM) system of bed 10 is armed. Thus, the illuminated indicia 144 reminds a patient not to get out of bed when the PPM system is armed.

Referring now FIG. 3A, second side 78 of housing 72 includes a dock 146 to secure a handheld phone 148 in place on the housing 72. In the illustrative example, the dock 146 is configured as a clamp that includes a pair of clamp members 150, 152. Clamp member 152 is spring loaded and is movable toward and away from clamp member 150 to permit the dock 146 to accommodate handheld phones of different sizes. A spring 154 is shown diagrammatically (in phantom) in FIG. 3A. Spring 154 spring biases clamp member 152. Clamp member 150, therefore, is a stationary clamp member in the illustrative example. In other embodiments both clamp members 150, 152 are movable and spring biases. Clamp members 150, 152 each have a notch 156 through which a plug 158 may access a port 160 of the handheld phone 148 when the handheld phone 148 is secured to the dock. Notches 156 in members 150, 152 allow phone 148 to be secured to housing 72 in either direction and yet port 160 is still accessible through one notch 156 or the other.

Still referring to FIG. 3A, first side edge 82 and second side edge 84 are each formed to include a cord wrap 162 around which slack of a cord 164 of the handheld phone 148 is wrapped, if desired. In the illustrative example, each of the cord wraps 162 is in the form of a cleat that has first and second cleat arms 162a, 162b. A plug port 166 is situated between the first and second cleats arms 162a, 162b of one or both of cord wraps 162. The plug port 166 is configured for receipt of a plug 168 of the cord 164 of the handheld phone 148. In the illustrative example, plug port 166 is a Universal Serial Bus (USB) port.

In the illustrative example of housing 72, another stay-in-bed indicia 144′ is provided on boss 142 on second side 78 of housing 72. Indicia 144′ is located generally above the handheld phone 148 when the handheld phone 148 is secured to the dock 146 and the second side 78 of the housing 72 is oriented generally vertically as shown in FIG. 3A. Indicia 144′ is illuminated at the same time as, and for the same purpose as, indicia 144 as described above. A nurse call button 100′ is provided on second side 78 of housing 72 and is located generally beneath the handheld phone 148 when the handheld phone 148 is secured to the dock 146 and the second side 78 of the housing 72 is oriented generally vertically.

Referring now to FIGS. 3B-3E, various applications of phone 148 are illustrated as being in use while phone 148 is docked to the patient control unit 70. In FIG. 3B, phone 148 is being used for a physician videoconference. In FIG. 3C, phone 148 is being used for a family videoconference. In FIG. 3D, phone 148 is being used to operate software downloaded from a healthcare facility. Such software includes, for example, software that permits a patient to select icons that result in a specific message being sent to an assigned caregiver's wireless portable communication device, such as another handheld phone. In FIG. 3E, phone 148 is being used for playing games. Phone 148 and housing 72 can also be viewed by a patient when head section 20 is raised and the patient is sitting up in bed as shown in FIG. 3F.

As shown diagrammatically in FIG. 4, a head-of-bed angle lockout system 170 includes a head-of-bed angle (HOBA) sensor 172 operable to determine an angular position of the head section 20, a HOBA lockout selector 174 and a controller 176. The controller 176 is coupled to the angle sensor 172 and the HOBA lockout selector 156 to receive signals therefrom. The controller 176 activates an actuator 178 to move head section 20 unless HOBA lockout system 170 is activated in which case head section 20 cannot be moved below a threshold angle, such as 30 degrees or 45 degrees, just to name a couple examples.

The head section 20 is diagrammatically shown in FIG. 20 to pivot relative to the upper frame 16 about a simple pivot axis. However, in some embodiments, the head section 20 pivots about a moving axis or a compound axis or the like. Accordingly, all types of connections for coupling one deck section of a bed to another are within the scope of this disclosure including simple pivots, compound pivots, reduced-shear pivots, and pivots having arcuate tracks or slots, just to name a few.

Still referring to FIG. 4, controller 176 is also coupled to user inputs 180, an alarm 182, and, optionally, a remote computer device 184, such as a computer of a nurse call system, electronic medical records (EMR) system, admission/discharge/transfer (ADT) system or the like. User inputs 180 include the user inputs described above in connection with FIG. 2, for example, as well as the user inputs on caregiver control pod 44 of FIG. 1. Alarm 182 is activated aurally, visually, and/or tactilely to indicate any alarm conditions sensed by controller 176. Thus, the controller 176 block in FIG. 4 is intended to represent, diagrammatically, all of the electrical components of bed 10 other than those that are illustrated separately in FIG. 4. In some embodiments, controller 176 comprises various circuit modules that interconnect in a network configuration, such as a controller area network (CAN). The details of this sort of bed network configuration are shown and described in U.S. Pat. Nos. 6,658,680; 6,691,346; 6,957,461; and 7,296,312; each of which is hereby incorporated by reference herein to the extent not inconsistent with the present disclosure which shall control as to any inconsistencies.

It is contemplated by this disclosure that the head-of-bed angle of the head section 20 may be measured or calculated with respect to any other portion of the bed 10, such as for example the upper frame 16, seat section 22, or base frame 14, or with respect to horizontal or vertical. Thus, it is contemplated that one or more types of angle sensors 172, such as a potentiometer, limit switch, ball switch, accelerometer, inclinometer, linear variable displacement transducer (LVDT), or hall effect sensor, just to name a few, may be provided on bed 10 to provide signals that are used to measure or calculate angles of bed components to arrive at the head-of-bed angle of head section 20. In some embodiments, the angle sensor 172 is included as a component of the actuator 178. The actuator 178 may comprise an electrical linear actuator, for example, in such embodiments.

Regardless of the type of sensor used, angle sensor 172 provides a sensor signal to controller 176 indicative of an angular position of the head section 20 of bed 10. When the HOBA lockout system 170 is disabled or deactivated (these terms are intended to be used interchangeably), actuator 178 is operable under the command of controller 176 to move the head section 20 between raised and lowered angular positions. FIG. 1 shows head section 20 in the lowered position, for example, and extreme uppermost dashed line in FIG. 4 is representative of the raised position of head section 20. In FIG. 5, head section 20 itself, is shown in an intermediate position between the raised and lowered positions.

HOBA lockout selector 174 has an on state and an off state. The controller 176 is prevented from signaling the actuator 178 to move the head section 20 below a threshold HOBA defined between the raised and lowered angular positions when the HOBA lockout selector is in the on state. The controller 176 is permitted to signal the actuator 178 to move the head section 20 throughout a full range of motion between the raised and lowered angular positions when the HOBA lockout selector is in the off state. Any attempt to lower head section 20 below the threshold angle when the HOBA lockout selector is in the on state is considered an alarm condition, in some embodiments, resulting in controller 176 activating alarm 182 and/or sending an alarm signal to remote computer device 184.

The HOBA lockout selector 174 includes a button or a membrane switch in some embodiments. Alternatively or additionally, the HOBA lockout selector 174 is shown on a touchscreen display of bed 10. In some embodiments, the HOBA lockout selector 174 is located on a surface of a barrier, such as footboard 40 or siderails 48a, 48b, 48c, 48d, for example. Typically, the surface on which selector 174 is located faces away from the patient supported on bed 10.

Additionally or alternatively, in some embodiments, the controller 176 is configured to receive a signal from remote computer device 184 to change the HOBA lockout selector 174 between the on state and the off state. The threshold HOBA is a fixed value that may be stored in a memory associated with the controller 176 in some embodiments. Alternatively or additionally, the threshold HOBA is selectable between first and second threshold angles, or really, any number of desired threshold angles. For example, the threshold HOBA may be selectable using a graphical caregiver interface of the patient support apparatus 10.

Referring now to FIG. 5, one example lockout selector 174 comprises a button that is pressed sequentially to toggle between the on and off states. The button is included as part of a membrane switch, for example. In the illustrative example, HOBA lockout selector 174 includes a visual indicator 186 to indicate whether the HOBA lockout selector 174 is in the on state or the off state. The visual indicator 186 includes a light, such as a light emitting diode, for example. The light is illuminated when the HOBA lockout selector 174 is in the on state and the light is off when the HOBA lockout selector is in the off state. In the illustrative example of FIG. 5, an indicia 188 indicates that the threshold HOBA is 30 degrees. In embodiments of bed 10 having multiple threshold HOBA's, other buttons similar to the illustrative button 174 are provided with their respective indicia indicating the associated HOBA threshold. Thus, buttons having 45 degrees, 60 degrees, and so forth indicate on indicia 188 are contemplated by this disclosure. Such buttons may be located adjacent each other on a control panel and then the caregiver selects the desired lockout angle for the threshold HOBA. Then, depending upon which button is selected, controller 176 prevents head section 20 from being lowered below the selected threshold HOBA indicated.

Although certain illustrative embodiments have been described in detail above, variations and modifications exist within the scope and spirit of this disclosure as described and as defined in the following claims.
