U.S. Patent Application No. 13 / 300,478 entitled " Dual Serial Bus Interface "filed November 18, 2011, assigned to the same assignee as the assignee of the present application, is also incorporated herein by reference in its entirety.

The present invention relates to a patient monitoring system for a hospital. More particularly, the present invention relates to a configurable patient monitoring system including a monitor and display assembly, an optional standalone display, an optional standalone monitor, one or more modules, and a plurality of patient parameter measurement devices.

A patient monitoring system is an electronic medical device that measures a patient's various vital signs and collects and processes all measured values as data and displays the data as graphics or numerical values on a viewing screen. The graphic data is continuously displayed as a data channel (waveform) on the time axis. Patient monitoring systems are placed close to the bed, a typical limited care unit, which continuously monitors the patient's condition through a measurement device attached to the patient and is visible to hospital personnel. Some patient monitoring systems can only be seen on the display of one place, while others can be connected to the network to display data in other places, such as a central monitoring station or a nursing room.

Portable patient monitoring systems can be usefully used by emergency medical service (EMS) personnel. These systems typically include a defibrillator with a monitor. Other portable units, such as a Holter monitor, are worn on the patient for a specified period of time and returned to the physician for evaluation of the data measured and collected.

The current patient monitoring system pulse oxygen saturation (SpO _2), electrocardiogram (ECG), invasive blood pressure (IBP), noninvasive blood pressure (NIBP), Electroencephalographs (EEG), body temperature, cardiac output, capnography (CO ₂₎ , Mixed venous oxygen saturation (SvO ₂ ), dual spectroscopy (BISx), and respiration can be measured and displayed. Patient monitoring systems can measure and display maximum, minimum and average values and frequencies, such as pulse rate and respiration rate.

The collected data can be transmitted via a fixed wired connection or wireless data communication. The power of the patient monitoring system can be supplied through the main power line or by the battery. Current patient monitoring systems are effective at monitoring the patient's condition and informing the healthcare provider of the change, but these systems do not have any drawbacks or limitations.

Typically, the patient monitoring system is provided with audible and visual alarms to alert the healthcare personnel of changes in the patient's condition. The alarm parameters are set by the healthcare worker. Nursing audible alarms can be too loud to distract attention from other patients or staff. Also, bright and blinking alarms of nursing use can distract other patients. Conversely, visual alarms of nursing use, which are more difficult to detect, may be visually confusing on the display of the monitoring system, making it difficult to visually perceive, and visual alarms may be difficult to distinguish sufficiently from other information on the display. In addition, it is difficult for the nurse to stop operating alarms, which may delay patient care. A typical user interface for alarm control is operated via a typical bush button or, in most cases, a touch screen or keyboard.

Thus, there is a need for a better alarm mechanism in a patient monitoring system that does not disturb the patient, while audible and visual alarms can be easily recognized by the nurse. In addition, an alarm device is needed to allow the waiting nurse to quickly stop the alarm and focus on the patient.

Current patient monitoring systems are traditionally focused in an integrated package that includes displays, cases, and electronics. This limits diversity and prevents users from tailoring these monitoring systems to their specific needs and available space. Thus, there is a need for a modular monitoring system in which each component is a separate element and can be connected in various configurations. In particular, it is necessary for the monitor to be able to be connected to a display which is commercially available (COTS) without an integrated display. This monitoring system allows the user to position and monitor the display in the most efficient manner to freely utilize useful areas near the patient.

In one embodiment, the monitor-display assembly includes a pod connection port for the addition of a capnography or multi-gas pod as described in detail below.

In one embodiment, the circuit boards of the monitor are all built into a separate internal chassis. Such a chassis may be detached from the case while maintaining the full functionality of the monitor. Each circuit board can be individually accessed so that service personnel can fault-diagnose all circuit boards / components without having to completely dismantle the monitor and easily replace any circuit board / component.

In one embodiment, the monitor-display assembly includes a printer slot to extend the functionality of the monitor. In one embodiment, the printer accommodates 50 mm paper.

In one embodiment, the monitor-display assembly includes a handle that rotates up and down. When the handle is released or released while held in the hand, it progressively descends to its base downward position. In one embodiment, the rotational damper attenuates the downward movement of the handle (when released from its upper position) so as not to hit the monitor-display assembly significantly. This allows the handle and monitor-display assembly to be quietly used so as not to disturb the patient. According to one embodiment, the handle also has the ability to stop at a predetermined set-point at which the display is vertically balanced with respect to the floor surface when the monitor-display assembly is moved using the handle. This feature allows the monitor-display assembly to be held and walked very comfortably using the handles, so that the user's feet are not disturbed and the user's arm / hand is not subjected to any uncomfortable force.

In one embodiment, the housing of the monitor-display assembly is fabricated using Sabic Lexan EXL plastic so that the monitor-display assembly can withstand inadvertently dropping or chemical cleaning or excessive heat. In one embodiment, the monitor-display assembly does not exceed 9 pounds in weight.

In one embodiment, the display includes a 12.1 inch touch screen and can display up to eight waveforms. In one embodiment, the monitor-display assembly includes a speaker for a voice alarm.

In one embodiment, the external display includes an integrated visual alarm disposed on the front and back of the monitor-display assembly. These alarms are larger than current visible alarms and provide better visual indication to healthcare personnel during alarm situations. In one embodiment, the alarms, etc., are illuminated in red, amber, and blue to indicate priority alarms, high, medium, and low priority alarms. The alarms and the like can be configured to limit the minimum level of alarms that can be activated by the user regardless of the on-screen alarm display and / or the alarm audio. A continuous glass plate forms the front of the display and the outer surface of the display is secured with a metal band surrounding it as a frame to firmly reinforce the display. The glass plate does not include bezels and has a dual function with a touch screen and a lens for visual alarms and a light scattering means, thereby reducing the number of parts. The glass plate touch screen is provided as a continuous surface on the front side. This facilitates cleaning since there is no edge found in a typical bezel-like configuration in which there is a gap in which contaminants accumulate. In one embodiment, the metal band extends slightly beyond the touch screen to protect the glass plate when dropped to the front side. It will be appreciated by those skilled in the art that a metal band / frame with a planar touch screen without a bezel causes the monitor-display assembly to exhibit the same shape as it is contemporary. In other words, the monitor-display assembly will look similar to consumer electronics such as flat screen televisions and cell phones. This can help the patient or his / her family get used to it because the display looks similar to a home electronic device. The monitor-display assembly also has a soft edge as part of the design to make it look more friendly and friendly rather than industrial.

The light behind the glass plate delivers a beam of light of a reasonable wavelength to indicate the alarm. In one embodiment, the black frame is silk screen printed on the back of the glass plate around the periphery. In one embodiment, the black frame is made of ink that is silk screen printed or sprayed on the back side of the glass plate except for the border area. In another embodiment, the black border of the display device allows the light to pass through to allow the alarm to be activated and to alert the visual alarm, whilst the border appears to be uniform as if it were continuous.

In another embodiment, the border area used for visual alarms includes hand holes that allow light to pass through, while allowing the border to look uniform as if it were continuous. This provides a clean, flat modern appearance that does not indicate that there is an alarm until the actual alarm is activated.

In one embodiment, a nurse alarm signal comprising a flash rate for display and audio of an audible alarm is driven and controlled by the monitor.

In one embodiment, the external display includes an ambient light sensor that senses the ambient brightness and adjusts the brightness of the display. In a dark environment, ambient light sensors will automatically dim the display and alarms. This will reduce the illumination, for example, so that the patient does not disturb the patient as a dimmer if the patient is asleep. In a bright, illuminated environment, the ambient light sensor will automatically brighten the display. This function can be released by a button on the display.

In one embodiment, the external display includes capacitive buttons on the front of the touch screen that can be programmed by the user to perform various functions. In various embodiments, the button is a metal plate or other conductive material that utilizes commonly used touch and / or pressure sensitive techniques. These buttons are arranged significantly larger than the small touch screen buttons, so that they can be easily accessed. In one embodiment, the button is located on the upper side of the front of the display. In another embodiment, the button is located at the right side of the display. In addition, the buttons are not obscured by other buttons or user interface elements and are easy to find. The monitor 's circuit senses when the button is touched by the operator and the monitor performs the programmed function.

In one embodiment, the button is programmed to deactivate the alarm when touched. This allows the healthcare worker to quickly stop the alarms and reset the alarms to meet the patient's needs and prevent them from interfering with other patients. Since the alarms are generated in response in critical situations, the means for stopping and / or resetting these alarms can be readily identified and operated quickly. In another embodiment, the button is programmed to recognize the patient when touched. In another embodiment, the button is programmed to initiate NIBP measurements when touched. In another embodiment, the button is programmed to return to its home screen when touched. In another embodiment, the button is programmed to print the display when touched. The button can be programmed to stop the alarm to simplify the operation required by the nurse to silence the alarm. However, it will be understood that, if the operator is an expert, the button may be programmed to perform various functions without being limited to those mentioned above.

In another embodiment, the display comprises a section of the touch screen programmed for control of an alarm or the like.

In one embodiment, the external display includes a side backlight power button having a power symbol that turns green when the monitor-display assembly is switched on.

The display is housed in a metal band and finished with powder coating. The back of the monitor-display assembly includes a mounting pattern for a standard 75 mm Video Electronics Standard Association (VESA) mount.
