The present disclosure relates to architectural systems, such as headwalls, columns, and ceiling-suspended arm assemblies used in hospitals, and particularly to an architectural system adaptable to patient acuity level. More particularly, the present disclosure relates to an architectural system that is configured to deliver services, such as medical gases, to a patient and/or that is configured to support patient-care devices for delivering intensive care services to a patient.
Architectural systems, such as headwalls, columns, and ceiling-suspended arm assemblies, through which medical gases are accessible via medical service outlets are known. Headwalls, columns, and arm assemblies having rails, tracks, or brackets for attachment of patient-care devices and having electrical outlets for delivering power to the patient-care devices are also known. Patients in critical condition are oftentimes located in an intensive care unit of a hospital, whereas patients in stable condition are oftentimes located in a standard patient room. Architectural systems in intensive care units are generally configured to hold more patient-care devices and provide more types of medical services than architectural systems found in a standard patient room.
The numbers of patients in critical condition and the numbers of patients in stable condition fluctuate in a hospital over time. Thus, at any given time there may be either a shortage or excess of spaces for patients in an intensive care unit. In addition, at any given time there may be either a shortage or surplus of standard hospital rooms. Thus, there is a need for an architectural system that is adaptable to patients having high, medium, and low acuity levels so that hospitals have the flexibility to meet the needs of the patient population at any give time.
According to this disclosure, an architectural system adaptable to an acuity level of a patient supported by a hospital bed in a patient room having a wall and a ceiling is provided. The architectural system comprises a wall unit coupled to the wall and having a cavity, a ceiling unit coupled to the ceiling, and a column coupled to the ceiling unit for movement between a first position in which at least a majority of the column is situated in the cavity and a second position in which the column is situated outside the cavity.
Various patient-care devices and equipment are attachable to the column. Such patient care devices include, for example, IV racks, infusion pumps, ventilation equipment, heart rate monitoring equipment, and patient data acquisition equipment. In an illustrative embodiment, a number of medical service outlets, such as gas outlets and electrical outlets, are coupled to the column. Also in the illustrative embodiment, a number of doors are coupled to the wall unit for opening and closing the cavity. Thus, when the column is in the cavity, the doors may be moved to closed positions shielding the column and the equipment carried by the column from view and blocking access to the medical service outlets on the column. Opening the doors, but leaving the column in the cavity of the headwall unit, permits access to some of the medical service outlets and to some portions of the equipment carried by the column. When the column is moved out of the cavity, all of the medical service outlets and all pertinent portions of the equipment carried by the column are accessible.
Also according to this disclosure, a ceiling unit having one or more pieces of equipment coupled thereto is provided. Such equipment includes, for example, a reading light, an examination light, a display screen, air curtain generation equipment, a privacy curtain, a temperature sensor, an air quality sensor, an air purifier, aroma therapy equipment, a motion sensor, and a proximity sensor. In one illustrative embodiment, an arm assembly is coupled to the ceiling unit and supports an overbed table. The arm assembly permits the overbed table to be moved from one side of a hospital bed to an opposite side of the hospital bed.
A mobile cart is also disclosed herein. In an illustrative embodiment, the mobile cart comprises an upstanding pedestal, a plurality of legs coupled to a bottom of the upstanding pedestal, and a plurality of wheels. Each wheel is coupled to a respective leg of the plurality of legs. The legs, along with the wheels coupled thereto, are each movable between a first position extending outwardly from beneath the upstanding pedestal and a second position tucked beneath the upstanding pedestal. The mobile cart is attachable to a ceiling-mounted column or an arm assembly. The mobile cart is also attachable to a hospital bed to be transported with the bed. When the mobile cart is attached to either the column, the arm assembly, or the bed, the wheels of the mobile cart are spaced apart for the floor. A headwall unit having a cavity configured to receive the mobile cart is also disclosed. The mobile cart carries one or more pieces of patient-care equipment such as, for example, an IV pole, an infusion pump, a ventilator control unit, a gas tank, a gas control unit, a vital signs monitor, an on-board computer, a receiver, a transmitter, and a battery.
Further according to this disclosure, a set of hospital equipment comprises a headwall, a blanket, a unit housed in the headwall, and a hose coupled to the blanket and coupled to the unit, a thermoregulation medium being moved between the blanket and the unit through the hose. The thermoregulation medium includes, for example, heated air, cooled air, a heated liquid, or a cooled liquid. In some embodiments, in which the thermoregulation medium is heated or cooled air, the blanket has a plurality of perforations through which the heated or cooled air is expelled.

Rollers 124 each have shafts 134 that are coupled to side portions 132 and that extend horizontally therefrom in a cantilevered manner toward associated track members 120. As columns 40, 42 move along tracks 98, such as, for example, in directions 136 away from respective cavities 34, 36 as shown in
According to this disclosure, housing 76 carries electrical circuitry to control the operation of display screen 78. In some embodiments, housing also carries electrical circuitry to control the operation of display screen 110 and lights 100. In other embodiments, some or all of the circuitry that controls the operation of screens 78, 110 and lights 100 are housed in portions of head wall unit 32. Such circuitry includes for example, one or more of a microprocessor or microcontroller, input/output circuitry, signal conditioning circuitry, signal conversion (analog-to-digital and/or digital-to-analog) circuitry, power conditioning circuitry, memory circuitry, and the like. In addition, a user interface is provided on column 42 to permit a user to enter commands and retrieve data for display on screen 78. In the illustrative embodiment, screen 78 is a touch screen and the user input on column 42 comprises user input buttons 138 displayed on screen 78 as shown, for example, in
In some embodiments, the electrical circuitry that controls the operation of display screen 78 is coupled to the hospital's computer network or ethernet. In such embodiments, any of the information available on the network is viewable on display screen 78. For example, a caregiver is able to retrieve a patient's medical records (e.g. laboratory test results, medical diagnosis, patient charts, x-rays, and so on) from the network for viewing on screen 78. In addition, patient point-of-care data, such as vital signs data (e.g. heart rate, blood pressure, neurological activity, respiration rate, patient temperature, pulse oximetry) and data associated with the operation of patient-care equipment (e.g. data from one or more ventilators, infusion pumps, electrocardiographs, electroencephalographs), may be displayed on screen 78. Thus, the circuitry associated with screen 78 is programmed and/or configured to receive and process various types of data signals indicative of the information to be displayed on screen 78. It is within the scope of this disclosure for all types of data associated with the care of a patient to be displayed on screen 78. In addition, it is within the scope of this disclosure for screen 78 to display multiple types of data simultaneously, such as in a split screen format. Furthermore, in those embodiments in which the hospital computer network is coupled to the Internet, then information accessible via the Internet is also able to be displayed on screen 78.

A user interface is provided on one or both of columns 40, 42 or on headwall unit 232. A user inputs operational parameters, such as, for example, fan speed (high, medium, low), air temperature, and air humidity, to the controller via the user interface. In addition, system 330 has various sensors, such as, for example, a fan speed sensor, a temperature sensor, and a humidity sensor that provides feedback to the controller so that appropriate commands from the controller can be provided to air curtain generator 272, the heating system, and the humidification system to adjust the operation of these devices, if appropriate.
According to one aspect of the present disclosure, a patient rests on a hospital bed 534 in an environmentally-controlled hospital room 532 as shown in
Bed 534 includes a pendant controller 544 that a patient uses to control heating/cooling unit 538 in a desired manner when pendant controller 544 is not locked out. In some embodiments, pendant controller 544 also is used to control other bed functions, such as articulation, raising, and lowering of the bed deck, and to control room entertainment and communication functions, such as television, radio, and nurse call. Bed 534 includes a footboard 546 having a control panel 548 that is used by a caregiver to control operation of unit 538, to control operation of various bed functions, and to control various entertainment and communication functions. Control panel 548 is also used by the caregiver to lock out one or more functions of pendant controller 544. For example, the caregiver can lock out the ability of pendant controller 544 to operate unit 538.
An ceiling unit or overhead canopy 550 is coupled to a ceiling 552 of hospital room 532 above bed 534 as shown in
In some embodiments of room 532, the room lights are controlled to dim slowly as the daytime turns to evening. In addition, a recording of evening sounds, such as owls, night birds, crickets, and wind in the trees is played by audio equipment housed in overhead canopy 550. Eventually, the room lights are turned completely off and the night sounds fade away. In other embodiments of room 532, a video screen similar to or larger than video screen 558 is mounted to a room wall, preferably a wall that confronts the foot end of bed 534. In such alternative hospital rooms, television images, internet images, educational information, patient schedule, imagery to promote relaxation, and video conferencing images are selectively displayed on the video screen.
Bed 534, unit 538, and ceiling unit 550 each have their own controllers for monitoring and controlling the various functions associated with these devices. Each of such controllers include, for example, one or more microprocessors, microcontrollers, memory circuitry, input/output circuitry, signal conditioning circuitry, signal conversion circuitry, power conditioning circuitry, and the like. It is within the scope of this disclosure for each of the controllers of bed 534, unit 538, and canopy 550 to be coupled to the hospital computer network to exchange data with the network. In some embodiments, parameters for controlling bed 534, unit 538, and canopy 550 are entered by computers that are located remotely from room 532. Thus, for example, if a patient places a nurse call requesting the heating/cooling function of unit 538 and blanket 536 be adjusted or discontinued, the nurse receiving the call is able to adjust the amount of heating/cooling provided to the patient via blanket 536.
