Description

CONFIGURABLE, PORTABLE PATIENT MONITORING SYSTEM FIELD OF THE INVENTION The present specification generally refers to hospital-based patient monitoring systems. More particularly, the present specification relates to a configurable patient monitoring system comprising a monitor and screen assembly, optional independent screens, optional independent monitors, one or more modules, and a plurality of devices for measuring patient parameters.

BACKGROUND OF THE INVENTION A patient monitoring system is an electronic medical device that measures the different vital signs of a patient, collects and processes all measurements as data, and then displays the data graphically and / or numerically on a viewing screen. The graphical data is continuously displayed as data channels on a time axis (waveforms). Patient monitoring systems are positioned near hospital beds, usually in critical care units, where they continuously monitor the patient's status by means of measuring devices attached to the patient and can be seen by the hospital staff. Some patient monitoring systems can only be seen on a local screen, while others can be linked to a network and thus display the data in other locations, such as central monitoring or nursing stations.

Portable patient monitoring systems are available for use by Emergency Medical Services (EMS) personnel. These systems usually include a defibrillator along with the monitor. Other portable units, such as Holter monitors, are worn by the patients for a particular period of time and then returned to the doctor for the evaluation of the measured and collected data. Current patient monitoring systems are capable of measuring and displaying a variety of vital signs, including, pulse oximetry (Sp02), electrocardiography (ECG, Electrocardiograph), invasive blood pressure (IBP, Invasive Blood Pressure), non-invasive blood pressure (NIBP, Non-Invasive Blood Pressure), mixed venous oxygen saturation (Sv02), bispectral index (BISx), and respiration. Patient monitoring systems are able to measure and display maximum, minimum and average values and frequencies, such as pulse and respiratory rate.

The collected data can be transmitted through fixed wired connections or wired data communication. The energy to the patient monitoring systems can be supplied through a main power line or through batteries. While current patient monitoring systems are effective in monitoring patient conditions and notifying changes to medical personnel, they are not without certain drawbacks and limitations.

Patient monitoring systems are usually equipped with audio and visual alarms to notify medical personnel of changes in patient status. The alarm parameters can be set by the medical staff. Audible nurse alarms can often be too loud and distract other patients and staff. Bright, flashing visual nurse alarms can also distract other patients. Conversely, the more subtle visual nurse alarms may be too difficult to visualize, which may be a result of visual clutter on the monitoring system screen or because the visual alarm is not sufficiently differentiated from other information in the screen. In addition, it can be difficult for nurses to silence an active alarm, delaying care at patient. The typical user interface for alarm control is operated by means of traditional push buttons or in many cases a touch screen or keyboard.

Therefore, there is a need for a better alarm mechanism in patient monitoring systems, in which audible and visual alarms are easily recognized by nurses while not bothering patients at the same time. In addition, there is a need for an alarm mechanism in which an assistance nurse can quickly silence the alarm and then focus on the patient's needs.

Current patient monitoring systems are traditionally grouped into an integrated package that includes the screen, enclosure, and electronics. This limits flexibility and prevents users from customizing the monitoring system to their specific needs and available space. Therefore, there is a need for a modular patient monitoring system in which the individual components are discrete and can be connected in different configurations. Specifically, there is a need for a monitor that does not have an integrated screen and can be connected to a generic commercial or common screen (COTS, Commercial Off-The-Shelf). Such a monitoring system would enable users to position the screen and monitor in the most efficient manner, thus releasing valuable area in the patient's vicinity.

DETAILED DESCRIPTION OF THE INVENTION In one embodiment, the present specification is directed to a configurable patient monitoring system comprising a plurality of non-integrated components that include a screen and monitor assembly, optional additional independent screens, optional additional independent monitors, one or more modules, and at least one device for measuring patient parameters. A variety of patient parameters can be monitored and parameter measurement devices are connected to the system via dual serial bus (DSB) connectors and DSB cables.

The DSB interface comprises a first serial protocol and a second serial protocol, wherein the first protocol is a universal serial bus (USB), Firewire, or Ethernet protocol and the second serial protocol is a serial protocol of low power (LPS, Low Power Serial). The DSB interface manages the power distribution within the system by providing 5 V via the USB or 3.3 V protocol via the LPS protocol to the connected devices. Within the DSB interface, each component of the patient monitoring system is a DSB central (Host), DSB device, or both a central DSB and DSB device. A DSB exchange is in communication with and can supply battery operation and charging power to a connected DSB device and additionally contains a switched auxiliary voltage supply (AVS, Auxiliary Voltage Supply) that can provide up to 15 W of power to the attached DSB devices for battery recharge or other high energy needs. The DSB exchange recognizes the power requirements of the attached devices and switches the power delivery accordingly. The DSB interface is presented in greater detail in the pending United States Patent Application Number 13 / 300,478, entitled "Dual Serial Bus Interface", filed on November 18, 2011 and signed by the Applicant of the present invention, which is incorporated herein by reference.

Monitor and Display Assembly In one embodiment, the patient monitoring system includes a combined monitor and screen assembly, where the monitor is fixed securely and immovably to the back of the screen and the screen is directed by the monitor.

In one mode, the monitor interfaces with the modules and allows communication with external devices.

The monitor is similar to a CPU tower and provides a coupling for a module and parameter recorders. In one mode, the monitor contains a bay that provides power and communication for a private Spacelabs module. In one modality, the monitor can support both current and old modules and also patient parameter cables from the user-side device (FED, Front-End Device). In one mode, the monitor contains four USB ports to interface with devices including, but not limited to, keyboards, mice, barcode scanners, and removable disk drives. A patient-driven activity center (PWH, Patient Worn Hub), a small, portable stand-alone monitor described in co-pending US Patent Application Number 13 / 300,526, entitled "Self-Contained Patient Monitor", (Monitor Autonomous of Patients) filed on November 18, 2011, and assigned to the Applicant of the present invention, which is incorporated herein by reference, may also be connected. The PWH can also communicate wirelessly with the monitor. In these scenarios, the monitor acts as the central DSB and the PWH is the DSB device.

In addition, third-party devices can be connected to the monitor via Device Interface Cables, which translate the output of the third-party device to the protocol embedded in the DSB connector. The Cable Device interface has a DSB connector on one end and a cable connector on the other end to interface with the central (host) and the third party device, respectively. The Device Interface Cable is described in greater detail together with the PWH in the application referenced directly in the previous paragraph.

In one mode, the monitor contains a DVI port to allow the connection of an independent external display. The monitor also contains an Ethernet port for communication with other monitors and hospital infrastructures.

In one mode, the monitor contains an alarm relay output for an external nurse alert. This port is used for communication with an external display as described above. In one mode, a port is used to carry the signal to activate the alarm lights and the audio alarm, eliminating the need for two discrete cables and two discrete ports. In one modality, the monitor contains an additional nurse alert port that can be used with an independent external nurse alert (not on a screen). The monitor also contains a synchronous data link control (SDLC) port. For communication with the bays of the module of expansion that allow the user to use more modules through a device. In one mode, the monitor contains a serial port for touch screen communication, software updates and data logging. In one embodiment, the power is supplied to the monitor and display assembly by means of a DC power input. In one embodiment, the monitor and display assembly includes an equipotential terminal to ground the monitor. The monitor and display assembly also contains a rechargeable battery that is used in the event of power interruption to backup the module data, energize external nurse alerts, and energize the infrared (IR) receiver.

In one mode, the monitor uses "smart" lithium-ion batteries to provide long battery life and safety. The design provides a common form factor interlocking insertion of incompatible batteries. A built-in microcontroller monitors the conditions of charge, discharge and high temperature.

Thermal and current fuses are also provided as redundant safety features. One mode uses the Inspired Energy NI2040HD24 Smart Battery that includes a rechargeable lithium-ion battery and a battery management module. The battery consists of 9 cells rechargeable lithium-ion batteries of size 18650, assembled in a configuration of 3 in series / 3 parallel (3S 3P). Each cell has an average voltage of 3.6 V and a typical capacity of 2.4 Ah giving a battery pack of 10.8 V and 7.2 Ah. The battery is able to communicate with the exchange or the charger through a common system management bus (SMBus). The protection is provided for excess load, excess discharge and short circuit. For redundancy, passive safety devices are integrated into the package to protect against overcurrent and excess temperature, and secondary overvoltage is implemented with a logic fuse and controller.

In one mode, the monitor can run for 8 hours with battery power while monitoring ECG, NIBP every 15 minutes and takes a log every 15 minutes.

In one modality, the monitor uses dynamic network access (DNA, Dynamic NetWork Access) to provide laboratory, pharmacy, graphics, intranet, and hospital information system (HIS, Hospital Information System) applications at the bedside. Medical staff is able to access this information using a Citrix client application that runs on the monitor. This requires a Citrix server to host the application to serve the monitors. Nurses and doctors can review information from multiple sources without leaving the patient's care area. Concise and complete electronic patient records are created effortlessly. In one modality, the monitor includes data reorganization (da ta shuffle) and barcode scanner support for rapid identification and transfer, free of patient information errors. With the DNA option, instant access to patient information is ensured through the network. This results in ensuring optimal patient safety while simultaneously maximizing caregiver efficiency. In one modality, the special feature Full Bed Review (Full Bed Review) provides the nurse or physician the ability to view, control, review, and remotely record patient data for any other bed in network or telemetry without leaving the patient's bedside In one embodiment, the special feature of remote view / alarm monitoring (Remate Viéw / Alarm Wa tch) allows the caregiver to see any parameter for any patient monitored in the network from any headend. During an alarm state, waveforms and numeric data can be saved and recorded for later review. In one modality, the special Alarm Limit Review feature provides the caregiver with an instant view of the alarm limits of the header for all active parameters for viewing or printing. In one modality, the special feature of the Clinical Event Interface (ICS) instantly transmits alarms and waveforms personal communication devices for immediate viewing, resulting in faster response times. In one modality, flexport interfaces with the patient's link data from independent devices, consolidation waveforms, data, and alarms within the monitor. The information is then integrated directly into the trends of the monitor for its output to HIS or CIS applications.

In one embodiment, the monitor and display assembly includes a compartment connection port for the addition of a capnography or multigas compartment as described below.

In one embodiment, the monitor circuit boards are all mounted on the removable internal chassis. The chassis can be removed from the enclosure while the monitor is still fully functional. Each circuit board is individually accessible to allow service personnel to easily troubleshoot all circuit boards / components and replace any board / components without having to disassemble completely the monitor.

In one embodiment, the monitor and display assembly includes a printer slot to expand the capabilities of the monitor. In one mode, the printer accepts 50 mm paper.

In one embodiment, the monitor and display assembly includes a handle that can rotate in up and down directions. When the handle is released or released, it gradually falls to its low position by default. In one embodiment, a rotational damper delays the downward movement of the handle (with the release, from its high position) such that the handle is not flogged in the monitor and display assembly. This allows the silent use of the handle and the monitor and screen assembly without disturbing the patients. According to one embodiment, the handle also has a stopping functionality at a predetermined reference point at which the monitor and screen assembly is balanced enabling the screen to be perpendicular to the floor when worn using the handle. This functionality allows the monitor and screen assembly to be quite comfortable to hold and walk with, using the handle, as it does not get in the way of the user's leg or impose uncomfortable forces on his arm / hand.

In one embodiment, Sage Lexan EXL plastic is used to house the monitor and screen assembly to allow the monitor and screen assembly to support unintentional dropping, chemical cleaning and excessive heat. In one embodiment, the monitor and display assembly weighs less than 4.08 kilograms (9 pounds).

In one modality, the screen includes a touch screen of 30.7 centimeters (12.1 inches) and is capable of representing up to eight waveforms. In one mode, the monitor and screen assembly contains speakers for audio alarms.

In one embodiment, the external display contains integrated visual alarm lights located on the front and back of the monitor and display assembly. These alarm lights are larger than the current visual alarms, providing a better visual indicator to the medical staff during alarm situations. In one mode, the alarm lights flash red, yellow, and cyan to indicate high, medium, and low priority alarms, respectively. The alarm lights are configurable by a user to define the minimum level of alarm lights that can be activated regardless of the on-screen alarm display and / or audio alarm. A piece of continuous, flat glass occupies the entire front of the screen and fits within a band metal that wraps the outer sides of the screen, like a frame, to give robustness. The glass piece does not contain any bevels and is duplicated as a touch screen and as the lens and medium of light scattering for the visual alarm, resulting in a reduced parts count. The flat touch-screen glass also provides a continuous surface presented on the front. This makes cleaning easier since there are no edges as found in typical bevel implementations that provide slits for the accumulation of contaminants. In one embodiment, the metal band extends slightly out past the touch screen to protect the crystal if it is dropped on your face. It should be appreciated by those experienced in the art that the metal band / frame with the flat bevel touch screen brings a contemporary look to the monitor and display assembly. In other words, the monitor and display assembly looks similar to consumer electronics such as flat-screen TVs and cell phones. This can help to facilitate and acclimatize the patient and the patient's family since the screen looks similar to an electronic home and family device. The screen monitor assembly also has soft edges as part of the design to make it look less industrial and more friendly and accessible A light source behind the glass transmits appropriate wavelengths of light to indicate alarms. In one embodiment, the black border is screen-printed on the back of the glass around the perimeter. In one embodiment, the black border comprises an ink that is screen-printed or sprayed onto a masked edge area that gives the appearance of a continuous and uniform black border but allows light to pass through when the alarm is activated, producing a visual alarm .

In another embodiment, the edge area used for the visual alarm contains small openings that make the edge appear continuous and uniform but allow light to pass through. This provides a clean, flat modern appearance that shows no indication of alarm until an alarm actually occurs.

In one modality, nurse alarm signals, including flash rates for the screen and audio for audible alarms, are directed and controlled by the monitor.

In one embodiment, the external display contains an ambient light sensor that detects the brightness level of the environment and adjust the brightness of the screen accordingly. In a darker or poorly lit environment, the sensor Ambient light will automatically dim the screen and alarm lights. This is particularly beneficial for cases in which the patient is sleeping, since the dimmer lights will be less likely to bother the patient. In a lighter or well-lit environment, the ambient light sensor will automatically brighten the screen. This feature can be deactivated by means of a button on the screen.

In one embodiment, the external display contains a capacitive button on the front of the touch screen that can be programmed by the user to perform a variety of functions. In different modalities, the button is a metal plate or other conductive material that uses any touch sensitive and / or commonly used technology. The button is large and is positioned prominently in comparison to a smaller touch screen button so that you can easily access it. In one mode, the button is located on the upper edge of the front of the screen. In another mode, the button is located at the bottom edge of the screen. In another mode, the button is located on the left edge of the screen. In another mode, the button is located on the right edge of the screen. In addition, the button is easier to find because it is not obscured by the clutter of other buttons or user interface items.

The circuits in the monitor detect when the button is touched by an operator and the monitor executes the programmed function.

In one mode, the button is programmed to suspend the alarm when it is touched. This allows the medical staff to quickly silence an alarm and reset the alarm indications, so that they can attend to the patient's needs and prevent discomfort to other patients in the area. Because alarms are produced in response to critical events, it is important that the means to silence and / or reset them are easy to find and quick to activate. In another mode, the button is programmed to admit the patient when touched. In another mode, the button is programmed to start NIBP measurement when it is touched. In another mode, the button is programmed to return the screen to its home screen when it is touched. In yet another mode, the button is programmed to print the screen when it is touched. The button would be mainly programmed to suspend the alarm to simplify the action required by a nurse to silence an alarm. However, someone experienced in the field will understand that the button could be programmed to perform a variety of functions not limited to those listed above.

In another embodiment, the screen contains or includes a section of the touch screen programmed for the control of the alarm light.

In one mode, the external display contains a backlight power button on the side with a power symbol that is green when the monitor and display assembly is turned on.

The screen is housed with a metal band and a powder coating finish. The back of the monitor and display assembly contains a mounting pattern for standard Video Electronics Standards Association (VESA) 75mm mounts.

External Display and Alarm Indicators In one embodiment, the patient monitoring system includes one or more optional independent screens as disclosed in U.S. Patent Application Number 13 / 300,462, entitled "Configurable Patient Monitoring System," (Configurable Patient Monitoring System) ), filed on November 18, 2011 and assigned to the applicant of the present invention, which claims priority of the Provisional Patent Application of the United States Number 61 / 415,799, entitled "Patient Monitoring System with Dual Serial Bus (DSB) Interface ", (Patient Monitoring System with Dual Serial Bus Interface (DSB)) and presented on November 19, 2010, both of which are incorporated herein by reference in its entirety Display In one embodiment, the patient monitoring system includes one or more optional independent monitors as disclosed in U.S. Patent Application Number 13 / 300,462, entitled "Configurable Patient Monitoring System," (Configurable Patient Monitoring System) , filed on November 18, 2011 and assigned to the applicant of the present invention, which claims priority of the United States Provisional Patent Application Number 61 / 415,799, entitled "Patient Monitoring System with Dual Serial Bus (DSB) Interface", (Patient Monitoring System with Dual Series Bus Interface (DSB)) and presented on November 19, 2010, both of which are incorporated herein by reference in their entirety.

Coupling Station In one embodiment, the monitor and display assembly is enabled for portability using a docking station that provides a quick undocking of a single button of the monitor assembly and screen while still maintaining patient monitoring for transport / emergency scenarios . The docking station allows flexibility and ease of use of the monitor and display assembly with respect to connection and disconnection of power, Ethernet, external display and other devices for measuring external patient parameters. In one embodiment, receptacles such as Ethernet connection, DVI for external display, USB, serial ports, audio / IR alert / external nurse receiver, power port and SDLC are duplicated at the docking station. In addition, the docking station allows for greater portability of the patient monitoring system in the hospital setting, where space is often limited and messy with other medical equipment. In one embodiment of the present invention, the patient cables are always attached to the patient, when the monitor and screen assembly is coupled and when it is uncoupled. Therefore, the wires do not need to be removed from the patient or the monitor and display assembly and remain connected to the patient in such a way that the patient can be continuously monitored.
