[0048] The following description, set forth in conjunction with the accompanying drawings, is intended to be a description of various exemplary embodiments of the disclosed subject matter. Specific features and functionalities are described in conjunction with each exemplary embodiment; however, it is apparent to those skilled in the art that the disclosed embodiments may be practiced without each of these specific features and functionalities.

[0049] Reference throughout the specification to "one embodiment" or "an embodiment" means that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment of the disclosed subject matter. Thus, the phrases "in one embodiment" or "in an embodiment" appearing in various places throughout the specification are not necessarily referring to the same embodiment. Furthermore, in one or more than one embodiment, the particular features, structures, or characteristics may be combined in any suitable manner. Furthermore, the embodiments of the disclosed subject matter are intended to cover modifications and variations thereof.

[0050] It must be noted that, unless the context clearly dictates otherwise, as used in the specification and the appended claims, the singular forms "a", "an", and "the" include plural referents. That is, unless otherwise clearly stated, as used herein, the words "a", "an", "the", etc. have the meaning of "one or more than one". In addition, it should be understood that terms such as "left", "right", "top", "bottom", "front", "back", "side", "height", "length", "width", "up", "down", "inside", "outside", "inside", "outside", etc. that can be used herein only describe reference points, and do not necessarily limit the embodiments of the present disclosure to any particular orientation or configuration. In addition, terms such as "first", "second", "third", etc. only identify one of the multiple parts, components, steps, operations, functions and / or reference points disclosed herein, and also do not necessarily limit the embodiments of the present disclosure to any particular configuration or orientation.

[0051] In addition, the terms "approximately," "about," "close," "slightly varying," and similar terms generally refer to ranges including identified values ​​within a margin of 20%, 10%, or preferably 5% in certain embodiments, and any values ​​therebetween.

[0052] All functionality described in conjunction with one embodiment is intended to apply to additional embodiments described below, except where expressly stated or where a feature or function is incompatible with the additional embodiment. For example, where a given feature or function is expressly described in conjunction with one embodiment, but not expressly mentioned in conjunction with an alternate embodiment, it is understood that the inventors intend that the feature or function may be deployed, utilized, or implemented in conjunction with the alternate embodiment, unless the feature or function is incompatible with the alternate embodiment.

[0053] During a medical event, a medical device may be used by a caregiver (e.g., first responder, paramedic, physician, nurse, rescue worker, etc.) to provide medical treatment to a patient, and / or may be used to monitor a patient. The medical device may be, for example, a patient monitor, a therapeutic medical device (e.g., a defibrillator, an automatic compression device, a ventilator, etc.), a therapeutic medical device / patient monitor, or a modular therapeutic medical device / patient monitor. These types of medical devices are examples only, and other types and combinations of medical devices are within the scope of the present disclosure.

[0054] The medical device may be configured to be coupled to one or more sensors. The sensor may include one or more combined therapy delivery / sensing components, such as defibrillation electrodes configured to sense and monitor the patient's electrocardiogram (ECG) and deliver electrotherapy. The medical device may collect data via one or more sensors. The data may include physiological sensor data and / or medical or resuscitation treatment data. Physiological sensor data may include, for example, invasive blood pressure (IBP), non-invasive blood pressure (NIBP), electrocardiogram (ECG) data, pulse oximetry data (SpO2), capnography data, methemoglobin (SpMet), hemoglobin, body temperature, brain oxygen saturation (rSO2), heart rate and / or other vital signs. Physiological data may also include imaging data, such as, for example, laryngoscopy and / or ultrasound. Medical or resuscitation treatment data may include, for example, CPR performance data derived from measurements obtained from a chest compression sensor (e.g., compression depth, compression rate, chest release, perfusion performance, etc.) and / or ventilation data from measurements obtained from an airway flow sensor (e.g., ventilation tidal volume, ventilation rate, minute ventilation, ventilation performance, etc.). These types of data are examples only and not limitations of the present disclosure, and are discussed in further detail below.

[0055] A medical device and one or more sensors can be coupled to each other via a data transmission cable. In order to enable these wired couplings, the medical device may include one or more data interface (DI) ports. Each data interface port can be configured to be removably coupled to a data transmission cable, which in turn is coupled to the sensor. The DI port can be a sensor-specific DI (SS-DI) port. For example, in various implementations, a sensor-specific DI port can be configured with a cable contact count and wiring allocation, (one or more) voltage and / or processor configuration for a signal processing protocol that is compatible with one type of sensor but incompatible with other types of sensors. For example, a sensor-specific DI port can be compatible with an invasive blood pressure (IBP) accessory (e.g., a sensor / data transmission cable combination for IBP), but may not be compatible with a capnography accessory (e.g., a sensor / data transmission cable combination for sensing exhaled airflow such as carbon dioxide). As an incompatible accessory, the capnography accessory may not physically mate with the IBP-specific port, and / or may not be electrically compatible, and / or may provide sensed data to the IBP-specific port that the IBP-specific port cannot process due to differences in data protocols for different sensor data types. The DI port may be a sensor-independent DI (SA-DI) port configured to capture a variety of sensor data types, each sensor data type provided via a data transmission cable configured to provide sensor data in a format compatible with the sensor-independent DI port. Thus, a caregiver can attach any SA-DI compatible sensor cable to any available sensor-independent DI port. The data transmission cable may include hardware compatible with the cable contact count and wiring assignments and (one or more) voltages of the sensor-independent DI port. In addition, the data transmission cable may include a processor, stored software, and a patient leakage current isolation portion that provides sensor data in an unrelated format, limits unrelated power delivery according to the needs of the sensor, and customizes the patient leakage current isolation portion for specific sensor power requirements.

[0056] In some implementations, the data transmission cable includes one or more lighting elements disposed on the cable, on a housing coupled to the cable, and / or on an electromechanical connector configured to connect a sensor device to the data transmission cable. The lighting elements may have different operating modes to indicate different status information associated with the data transmission cable and / or a sensor coupled to the data transmission cable, such as a power-on state, a power-off state, an authentication state, a sensor fault state, a sensor operating state, a sensor type, and / or a communication state in some examples. In some examples, the lighting elements may indicate status information based on color, continuity of illumination (e.g., flashing or continuous or various flashing rates), and / or the absence of illumination. In some embodiments, the data transmission cable includes a low light sensor electrically coupled to at least one lighting element and configured to disable illumination in low light conditions.

[0057] In some implementations, one or more lighting elements of the data transmission cable provide infrared illumination. For example, the wavelength of the infrared illumination may be in the range of 900-1750 nm. Infrared illumination may provide advantages in military settings by, for example, enabling identification of sensors using night vision goggles.

[0058] As described above, medical devices such as patient monitors or patient monitors / defibrillators typically include attachments for multiple sensors for effective patient care. Each sensor can be connected to the medical device via a wired cable that requires a DI port. For sensor-independent DI ports, multiple compatible and therefore potentially visually indistinguishable cables (at least from the port end of the cable) can be drawn from the medical device. In addition, these cables can cross, overlap or otherwise obscure the visibility of which cable is connected to which sensor device. For example, a medical device can provide three DI ports to enable connection to an IBP sensor, a temperature sensor, and an airway flow sensor.

[0059] In order to improve the ease of interpretability of a display area of ​​a medical device presenting information associated with multiple data transmission cables, in some implementations, one or more lighting elements of a data transmission cable can be illuminated in response to a user input at the medical device. For example, the user input can allow a user to uniquely match a specific display area (e.g., a data output) with a specific cable / sensor, thereby providing the advantage of quickly identifying which data transmission cable / sensor device combination is associated with which output. For example, the medical device may include a button and / or a touch screen control that is configured to accept a user query to identify the type of sensor on the data transmission cable. The host processor of the medical device can illuminate one or more lighting elements of the data transmission cable in response to a user input at the medical device. For example, the host processor of the medical device can illuminate (one or more) lighting elements in response to a user touch and / or other user input (e.g., a cursor or other optional screen indicator) of the display of the medical device.

[0060] In some implementations, the data transmission cable includes a cable processor configured to present information to a caregiver via (one or more than one) lighting element. In such an implementation, the host processor of the medical device can issue a command to the cable processor of the data transmission cable to cause lighting to be performed in response to user input.

[0061] In some implementations, the data transmission cable includes an identification contact / wire combination for cable identification query.A host processor of the medical device can provide a signal to the lighting element(s) via the identification contact / wire combination.

[0062] In some implementations, the data transmission cable includes a cable user interface, which includes a lighting element set or illuminated display configured to present caregiver feedback and / or prompts. Although prompts and / or feedback information can be presented at the display of the medical device, the display may be away from the caregiver or otherwise awkward for the caregiver to watch. In order to overcome this shortcoming, the data transmission cable user interface can be positioned or arranged along the cable, or positioned or arranged at the electromechanical connector interface of the sensor device near the caregiver providing care to the patient. Utilizing prompts and / or feedback information provided directly at the care point via the data transmission cable user interface, the caregiver does not need to turn his / her head to observe the screen that may be located or otherwise positioned at an inconvenient or uncomfortable viewing position. The user output can depend on the type of sensor coupled to the data transmission cable. For example, a data transmission cable with an airway flow sensor can present an airway flow sensor user interface. The airway flow sensor user interface can, for example, provide bag valve mask feedback for guiding and / or prompting the user to give ventilation according to a predetermined ventilation target (such as within a predetermined range of (one or more than one) ventilation tidal volume, ventilation rate and / or minute ventilation, etc.). In another example, a data transmission cable with a CPR compression sensor can include a CPR compression sensor user interface, which is used to prompt and / or guide the user to give chest compressions according to a predetermined chest compression target (such as within a predetermined range of (one or more than one) chest compression depth, chest compression rate and / or release speed, etc.). For example, the prompt presented at the user interface can include a digital value for illustrating the corresponding ventilation / compression parameter. Additionally or alternatively, if the ventilation and / or compression parameters are outside the desired target range, the user interface can provide indicative feedback to the user. For example, if the ventilation tidal volume is outside of a desired target range, a portion of the user interface may provide a visual indication that the user should be aware of how much tidal volume is being given to the patient (e.g., highlighting a numerical value representing the tidal volume, illuminating the background of the numerical value with a warning color (such as yellow, orange, or red, etc.), illuminating the numerical value itself with a warning color (such as yellow, orange, or red, etc.), etc.). Similarly, if the ventilation rate is outside of a desired target range, a portion of the user interface may provide a visual indication that the user should adjust how fast or slow the ventilation is being given (e.g., highlighting a numerical value representing the ventilation rate, illuminating the background of the numerical value with a warning color, illuminating the numerical value itself with a warning color, etc.). In some embodiments, when the compression depth is outside of a desired target range, the user interface may indicate (e.g., highlighting a numerical value representing the compression depth, illuminating the background of the numerical value with a warning color, illuminating the numerical value itself with a warning color, etc.) that the user should adjust a given chest compression depth.And when the press rate falls outside the expected target range, the user interface can similarly indicate (for example, highlighting the numerical value representing the press rate, illuminating the background of the numerical value with a warning color, illuminating the numerical value itself with a warning color, etc.) that the user is outside the target press rate range.

[0063] In some implementations, the medical device includes one or more removable sensor hubs that provide one or more DI ports. These DI ports can be sensor-independent DI ports, sensor-specific DI ports, or a combination thereof. The removable sensor hub can also include hardware and / or software controls for specific sensors or sensor combinations. For example, the sensor hub can provide pneumatic controls and pump systems for NIBP and / or capnography. One or more removable sensor hubs can be removably coupled to a medical device within a medical device housing or coupled to the outside of the medical device housing. The sensor hub can capture sensor data when physically coupled to the medical device and when physically separated from the medical device. The removable sensor hub can be communicatively coupled to the medical device via a wired or wireless connection.

[0064] When a removable sensor hub is used, the total number of cables communicatively connected to the medical device can be increased. For example, the medical device may include a display divided into multiple display areas on the screen, each area dedicated to displaying sensor data and / or status indications related to a given sensor connected to the medical device directly and / or via a sensor hub. In order to clarify the interpretation of various data, the systems and methods described herein provide the opportunity to visually connect a specific cable to a specific display area through user selection of the display area. For example, touching a segment of the display screen of the medical device can cause lighting on the cable at the far end of the medical device.

[0065] Additionally, the caregiver can place the sensor hub on a gurney or other support item near the patient and in a location that is easily visible and accessible to the caregiver. In implementations, the sensor hub can be light enough to be placed on the patient without any negative impact on patient care and / or resuscitation. Positioning the sensor hub as close to the patient as possible (including potentially on the patient) can enable the caregiver to provide care and view data displays on the sensor hub and / or connect or disconnect sensors with minimal interruption during the time they are focused on the patient, without having to take their attention away from the patient.

[0066] As with medical devices, in some embodiments, display areas of the sensor hub display are user-selectable to trigger lighting on corresponding cables. In this way, a user interacting with a sensor hub having multiple cables can quickly identify the correspondence between specific data and a specific cable.

[0067] Other capabilities and benefits of the teachings herein are described below.

[0068] Figure 1A and Figure 1B A cable status feedback mechanism in an example system 100 is illustrated, the example system 100 including a medical device 102 configured with a plurality of sensor-independent data interface ports and a data transmission cable 104 connected to the medical device 102. For example, the medical device 102 can provide treatment to a patient and / or monitor a patient and / or monitor treatment metrics for treatment provided by a caregiver. As illustrated, the medical device 102 includes a display 112 that presents a user interface. The user interface can provide treatment data (e.g., medical, resuscitation, etc.) and / or physiological data collected by various sensor devices (such as sensor devices connected via the data transmission cable 104, etc.) connected to the medical device 102 via one of the data interface port sets 110.

[0069] In some implementations, when a caregiver engages the medical device connector 108 of the data transmission cable 104 with one of the data interface ports 110 (e.g., port 110c, as illustrated), a first lighting element 106a (e.g., LED) disposed in the housing 114 of the data transmission cable 104 illuminates to confirm that the cable is connected to the medical device. For example, after detecting the connection between the data transmission cable 104 and the data interface port 110c, the state of the data transmission cable 104 can be changed from an unconnected state to a connected state, thereby triggering illumination. In some embodiments, the lighting of the first lighting element 106a is maintained for the duration that the data interface cable 104 is connected to the data interface port 110c of the medical device 102. In this way, a caregiver can visually confirm that a sensor element or sensor device connected to the data transmission cable is engaged with the medical device 102 without having to access the location of the medical device 102.

[0070] In some implementations, after transitioning to the connected state, the medical device 102 and the data transmission cable 104 participate in an authentication routine. For example, the data transmission cable 104 can transition to an authentication / identification state. During authentication, the medical device 102 can confirm the compatibility and authenticity of the data transmission cable 104, and then enable data communication between the medical device 102 and the data transmission cable 104. After successful authentication, in some embodiments, one or more areas of the housing 114 of the data transmission cable 104 are illuminated to indicate that the data transmission cable is now communicating with the medical device 102. In some examples, the indicator light can illuminate or move from a pending state (e.g., flashing, yellow, etc.) to an authentication state (e.g., steady lighting, green, etc.). The medical device 102 can also enable power to a sensor device connected to the data transmission cable 104. At this point, this state can be considered a port activity state. Upon activating the sensor device and confirming communication therewith, in some embodiments, one or more areas of the housing 114 of the data transmission cable 104 are illuminated to indicate that the sensor device connected to the data transmission cable 104 is now emitting sensor signals to be captured by the medical device 102. In some examples, the indicator light may illuminate or move from a pending state (e.g., flashing, yellow, etc.) to a connected state (e.g., steadily illuminated, green, etc.).

[0071] Go to Figure 1B In some embodiments, successful authentication of the data transmission cable 104 results in illumination of the second illumination element 106b, thereby alerting the caregiver that the sensor or sensor device attached to the data transmission cable 104 is connected to the medical device 102. The second illumination element 106b may remain illuminated while the state of the data transmission cable 104 remains in the port active state.

[0072] After transitioning to the port active state, in some implementations, additional setup is required before using certain sensors or sensor devices. Figure 1B As illustrated, the setup message 116 is presented in a user interface area of ​​the display 112 that corresponds to the sensor attached to the data transmission cable 104. For example, the user can select the area 116 of the setup message (e.g., using a touch gesture if the display 112 is touch-enabled; using a mechanical input device or mechanism, such as a navigation dial 120 on the front of the medical device 102; etc.) to engage in the setup routine. In another example, go to FIG. 2A to FIG. 2C , illustrates a series of stages in an invasive blood pressure (IBP) sensor setup routine.

[0073] In some implementations, turning Figure 2A, the IBP sensor setup routine begins by presenting an interactive setup dialog box in the user interface of the display 112 of the medical device 102. For example, the interactive setup dialog box is illustrated in a pop-up window 202 presented on a portion of the user interface of the display 112. In some embodiments, upon selecting a setting (e.g., by using the touch-sensitive display 112, by rotating the navigation dial 120 and pushing the dial 120 inwardly to make a selection, etc.), the user interface 202 is displayed. Figure 1B , the pop-up window 202 is displayed when the area 116 including the setup message is displayed in the medical device 102. In other embodiments, the pop-up window 202 is automatically launched upon successful transition to the port active state and the sensor attached to the data transmission cable 104 is recognized by the medical device 102 as an IBP sensor. The pop-up window 202 includes options for setting a source label 204 (e.g., IBP, ART, PAP, ICP, CVP, etc.) and selecting a display format 206 for metric display (e.g., S / D(M), S / D, (M)S / D, (M), etc., where S=systolic, D=diastolic, and M=mean).

[0074] In addition, the pop-up window 202 includes an identification control 208 for identifying the IBP probe corresponding to the pop-up window. For example, when the identification control 208 is selected, the first lighting element 106a and / or the second lighting element 106b can be controlled to provide the caregiver with a visual confirmation of the data transmission cable 104 connected to the probe involved in the setup pop-up window 202. In some examples, one or both of the lighting elements 106a, 106b can change color and / or flash for a period of time (e.g., up to several seconds). In one example, when the setup is initiated (e.g., including launching the setup window 202), the second lighting element 106b can flash, change color, increase intensity, or otherwise attract attention to the probe connected to the data transmission cable 104. Further for this example, if the caregiver fails to notice the visual identification (e.g., flashing, strobing, etc.) displayed by the second lighting element 106b, the caregiver can select the identification control to confirm which probe corresponds to the pop-up window 202.

[0075] In addition, the pop-up window 202 includes a zero probe control 210 for zeroing (initializing) the IBP probe sensor. In some implementations, the second lighting element 106b is illuminated with a first color (e.g., yellow, orange, red, etc.) indicating that a user action is required and a second color (e.g., green, blue, white, etc.) indicating that the data transmission cable 104 and / or the sensor device connected to the data transmission cable 104 are in a ready or active state. When the zero probe control 210 is selected, the first lighting element 106a and / or the second lighting element 106b can be controlled to provide a visual indication to the caregiver that the sensor of the IBP probe connected to the data transmission cable 104 participates in the zeroing process. As illustrated, for example, the second lighting element 106b is illuminated. In other examples, one or both of the lighting elements 106a, 106b can change color and / or flash for a period of time (e.g., up to several seconds).

[0076] Go to Figure 3 , illustrates a method 300 for automatically initializing an invasive blood pressure (IBP) probe connected to a sensor-independent data interface port of a medical device. For example, the method 300 may be performed by Figure 1A and Figure 1B The method 300 may be performed by a medical device 102 and a data transmission cable 104. For example, the method 300 may involve FIG. 2A to FIG. 2C A series of user interactions via the display 112 of the medical device 102 are illustrated.

[0077] In some implementations, method 300 begins by identifying a connection of an invasive blood pressure (IBP) probe to a data port of a medical device (302). For example, the medical device can use one or more connection detection cable contacts of the data port to detect a connection / disconnection between a data transmission cable and the data port of the medical device. For example, coupling the data transmission cable to the data port can involve detecting a ground connection between the data ports at the data transmission cable. For example, the medical device can detect a ground connection between the data ports at the data transmission cable. Figure 1A Connection identification is performed in the manner described.

[0078] In some implementations, communication with the IBP probe is authenticated (304). For example, the data transmission cable and the medical device may exchange authentication signals / messages during initiation of the communication coupling to verify that the data transmission cable and / or the IBP probe are recognized by the medical device and are compatible with the medical device. For example, the authentication signal / message may be exchanged between the data transmission cable and the medical device during initiation of the communication coupling to verify that the data transmission cable and / or the IBP probe are recognized by the medical device and are compatible with the medical device. Figure 1A and Figure 1B Authentication is performed as described.

[0079] In some implementations, a prompt is presented on the display for the caregiver to zero the IBP probe (306). To ensure accurate pressure measurement by the IBP probe, the transducer of the IBP probe may need to be zeroed when it is connected to a medical device (e.g., the transducer may need to be ventilated to atmospheric air for a period of time). Therefore, a zeroing process is performed on the IBP probe before using it. For example, Figure 2A As shown, the pop-up window 202 presents a zero probe control 210 for the caregiver to select. Figure 6B As shown, the IBP probe may include an alphanumeric display area, such as a display that presents a zero prompt (in Figure 6B , lighting element 606 (illustrated as the letter “Z”) and the like.

[0080] In some implementations, the method is pending until a caregiver selection is received at the user interface in response to the prompt (308). For example, the caregiver selection may be made via a touch-sensitive display of the medical device, a mechanical interface of the medical device (e.g., Figure 1A and Figure 1B The medical device may select a zeroing process by using a navigation dial 120 of the medical device or other input device in communication with the medical device. For example, the IBP probe may be in an unavailable state until a zeroing process has been performed. In other implementations, the medical device may detect the opening of a stopcock to vent the transducer to atmosphere, thereby automatically initiating a zeroing process without requiring a caregiver to provide confirmation via the medical device.

[0081] In some implementations, a zeroing process of the IBP probe is initiated (310). For example, a caregiver may automatically open a stopcock to vent the transducer to atmosphere. In another example, the probe may automatically vent itself in response to a zeroing command.

[0082] In some implementations, if the zeroing process fails (312), a failure routine is initiated (314). In some examples, the failure may include pulsation in the pressure channel, excessive noise in the signal, and / or transducer excursion greater than a predetermined threshold. For example, the failure may be presented on a display of the medical device. For example, the failure routine may include presenting a Figure 2A The same pop-up window 202 of FIG. 200 is displayed, wherein the zero probe control 210 is not selected, so that the caregiver can repeat the zeroing process. In another example, a guidance message may be provided, such as a message instructing the user to "fully open the stopcock".

[0083] Alternatively, if the zeroing process is successful (312), in some implementations, a prompt is presented to the caregiver on the display to select the type of IBP probe (e.g., pressure source) (316). In some examples, the type of IBP probe may include abdominal aortic pressure (ABP), arterial pressure (ART), central venous pressure (CVP), intracranial pressure (ICP), pulmonary artery pressure (PAP), umbilical artery pressure (UAP), aorta (AO), brachial artery pressure (BAP), femoral artery pressure (FAP), labial artery pressure (LAP), radial artery pressure (RAP), and / or umbilical venous pressure (UVP). In some embodiments, the type of probe may be identified by the data transmission cable 104 (e.g., based on information provided via the connected probe) and provided to the medical device 102 as a default label presented on the graphical user interface 112 (e.g., for optional overriding by the caregiver).

[0084] Go to Figure 2B , a pop-up window 220 covering a portion of the display 112 of the medical device 102 invites the caregiver to select the IBP tab. Controls for a tab set 222 including an IBP1 tab 222a, an ART2 tab 222b, a PAP tab 222c, a CVP tab 222d, and an ICP tab 222e are presented. As illustrated, the second control is labeled "ART2" because the user interface 112 already includes a first ART display area 224 corresponding to another IBP probe connected to the medical device 102.

[0085] return Figure 3 In some implementations, in response to the selection, a segment of the display is formatted to present a metric (318) associated with the IBP probe in accordance with the selection. In some examples, the metric may include a systolic value, a diastolic value, and an average. Additionally, a waveform may be presented demonstrating changes in invasive pressure over time. For example, a segment of the display may be configured to present both a label (e.g., "IBP1" or "ART2" or "PAP" or "CVP" or "ICP") and one or more metric values. Figure 2C As illustrated, for example, display area 224 is labeled "ART" and presents 112 / 74 (89). Additionally, display area 230 corresponding to the newly zeroed probe is labeled "ICP" and presents a single value of 12.4 mmHg.

[0086] In some implementations, during operation, when a caregiver selects a section of the display corresponding to an IBP probe (318), the corresponding probe or a cable connected to the probe is illuminated (322). Figure 1BAs described, the second lighting element 106b may light up, flash, change color, or otherwise draw attention to the probe corresponding to the second area (e.g., area 116) in the display selected by the caregiver. Figure 2C As illustrated, the second lighting element 106 b may strobe or flash to draw attention to the probe corresponding to the display area 230 .

[0087] Although method 300 is described according to a particular series of steps, in other embodiments, method 300 includes more or fewer operations. For example, the method 300 may be initialized with respect to the IBP probe. Figure 2A 206 of the display format control 206. Additionally, in some embodiments, certain steps of method 300 may be performed in a different order and / or in parallel. For example, before initiating the probe zeroing process (310), the caregiver may select a segment of the display (320) to cause illumination (322) to confirm that the caregiver is holding the appropriate probe for zeroing. Other embodiments of method 300 are possible.

[0088] Go to Figure 1C In some embodiments, the touch input functionality of the display 112 can be disabled, thereby allowing a person to manipulate the medical device 102 and / or maneuver within close proximity of the medical device 102 without inadvertently inputting commands or changing the contents of the display 112. In some examples, a manual lock control on the medical device 102 can be actuated to disable touch input, or an input device (e.g., a smartphone application, a laptop application, a remote control, a wireless keyboard, etc.) in communication with the medical device 102 can be used to disable touch input. As shown, a lock button 118 on the surface of the medical device 102 can be pressed. In another illustrative example, a lock slide button (not illustrated) can be shifted to a locked position to disable touch input.

[0089] In some implementations, when the touch-sensitive interface of the medical device 102 is disabled, a lock-enabled indicator is presented within the display 112. For example, as illustrated, a lock-indicating frame 122 surrounds the graphical interface presented on the display 112, including the lock icon 124. For example, the lock-indicating frame 122 may be a bright color (e.g., red, lime green, fuchsia, etc.) to draw attention to the touch screen that has been disabled. In other examples, the lock-enabled indicator may include a lock-enabled message on the display 112 (e.g., in an upper or lower area of ​​the display 112), a lighted indicator on the housing of the medical device 102 (e.g., a lighted lock button 118, etc.), and / or a message displayed when a user touches the surface of the display 112 (e.g., "Touch interface not available" in a pop-up window or as a display overlay, etc.).

[0090] After disabling the touch interface features of the medical device 102 , in some implementations, the user can use manual controls on the medical device 102 and / or other devices that communicate with the medical device 102 (e.g., a smartphone application, a laptop application, a remote control, etc.) to navigate the contents of the display 112 , navigate a list of options (e.g., a drop-down menu), and / or change parameter settings of the medical device 102 . Figure 1C The navigation dial 120 illustrated in the figure can be a knob configured to be twisted clockwise to navigate to the right and twisted counterclockwise to navigate to the left. In addition, the clockwise and counterclockwise twisting can cause downward and upward movement within a list such as a drop-down menu. In another illustrative example, a joystick-type control can be provided on the medical device 102 or in communication with the medical device 102 for submitting user interface interactions during the disabling of the touch-sensitive display. During navigation, various boxes or options can be highlighted within the display 112 to illustrate the current focus position. In addition, a cursor icon can be presented on the display 112 to assist the user in navigation. In some embodiments, while the touch screen feature is activated, the feature for navigating the options in the display 112 using a manual control such as the navigation dial 120 is disabled.

[0091] Figure 4A and Figure 4B-1 to Figure 4B-4 An example user interface output of a medical device 402 connected to a ventilation system 404 via a data transfer cable 406 is illustrated. Figure 4A , the display area 408 of the medical device 402 is presenting both the ventilation feedback display area 410a and the compression feedback display area 410b. For example, the compression feedback display area 410b may be generated based on a compression sensor device attached to the medical device 402 via a separate data transmission cable. For example, as further described below, the ventilation feedback display area 410a may be generated based on a ventilation sensor device attached to the medical device 402 via a separate data transmission cable.

[0092] In the ventilation feedback display area 410a, an amount 412a (e.g., 433 mL) and a rate 412b (e.g., 5 ventilations per minute) are indicated. For example, the amount 412a and the rate 412b may indicate feedback 412 related to the most recent ventilation delivery. In addition, the ventilation feedback display area 410a includes a countdown icon 414 that indicates coaching feedback presented to the caregiver for the next ventilation.

[0093] The ventilation system 404 includes a lighting element (e.g., an LED display) 416. The lighting element 416 is disposed on or near a connector 418 of the data transmission cable 406. In some embodiments, as described below with respect to Fig. 7A As described in further detail, the lighting element 416 is part of the data transmission cable.

[0094] In some implementations, the lighting element 416 is controlled by a processor of the medical device 402 and / or the data transmission cable 406 to reproduce a portion of the feedback 412 and / or the instructional prompt 414. For example, Figure 4B-1 to Figure 4B-4 , illustrating a lighting element 416 of a ventilation system 404, thereby presenting a lighting element 416 for presenting a lighting element 416 of a ventilation system 404, and ... of a ventilation system 404, and thereby presenting a lighting element 416 of a ventilation system 404, and thereby presenting a lighting element 4 Figure 4A The ventilation feedback display area 450 on the medical device 402, etc. is coordinated with the display. Figure 4B-1 4, the lighting element 416 of the ventilation system 404 is blank (e.g., not illuminated, illuminated in a primary color such as white, etc.), and the corresponding circle in the prompt graphic 452a of the ventilation feedback display area 450 is also blank or empty. For example, the empty circle can prompt the caregiver to initiate the next ventilation using the ventilation system 404.

[0095] Go to Figure 4B-2 , the lighting element 416 of the ventilation system 404 has a smaller illuminated or colored (e.g., green, yellow, etc.) circle at the center of the lighting element 416 that extends less than half of the radius of the circular lighting element 416. The corresponding circle in the prompt graphic 452b of the ventilation feedback display area 450 is also filled in approximately the same manner (e.g., using a color, fill pattern, etc.). For example, the partially filled circle can prompt the caregiver to continue delivering air to the patient via the ventilation system 404 (e.g., the target volume has not yet been reached). For example, when the circle in the prompt graphic 452b of the ventilation feedback display area 450 is filled with the color yellow, thereby indicating that the ventilation tidal volume and / or ventilation rate is outside of (one or more than one) corresponding target ranges, the lighting element 416 of the ventilation system 404 can then be illuminated with the same yellow color. Similarly, when the circle in the prompt graphic 452b of the ventilation feedback display area 450 is filled with the color green, thereby indicating that the ventilation tidal volume and the ventilation rate are within the respective target ranges of the ventilation tidal volume and the ventilation rate, the lighting element 416 of the ventilation system 404 can be illuminated with the same green color. Therefore, the yellow warning color can provide an indication that one or both of the ventilation tidal volume and the rate are outside the desired target range, so that the caregiver will need to consider how to adjust his / her application of manual ventilation for these two parameters. Similarly, the green color can provide an indication that both the ventilation tidal volume and the rate are within the desired target range, thereby giving the caregiver the following comfort: the manner in which he / she is providing manual ventilation is clinically desired. For example, a partially filled circle can prompt the caregiver to continue to deliver air to the patient via the ventilation system 404 (e.g., the target volume has not yet been reached), or can simply indicate that air is being delivered to the patient via the ventilation system 404.

[0096] Figure 4B-3The lighting element 416 of the ventilation system 404 is shown having an illuminated or colored (e.g., green, yellow, etc.) larger circle in the center of the lighting element 416 that extends greater than half the radius of the circular lighting element 416. The corresponding circle in the prompt graphic 452c of the ventilation feedback display area 450 is also filled in approximately the same manner (e.g., using a color, fill pattern, etc.). For example, an increasingly filled circle presented via both the lighting element 416 and the ventilation feedback display area 450 can provide feedback to the caregiver that air delivery to the patient is getting closer to a target amount.

[0097] exist Figure 4B-4 , the circular lighting element 416 of the ventilation system 404 is substantially illuminated. The corresponding circle in the prompt graphic 452d of the ventilation feedback display area 450 is also completely filled (e.g., using a color, fill pattern, etc.). For example, the fully colored / illuminated circle presented via both the lighting element 416 and the ventilation feedback display area 450 can provide the caregiver with feedback that the delivery of air to the patient has reached the target amount. At this point, in some embodiments, the displays 416, 450 can remain substantially the same for the pause period before the delivery of the next ventilation, so that the caregiver will again be prompted to Figure 4B-1 The prompts presented in the display prompt to deliver air to the patient. In some embodiments, Figure 4B-2 and Figure 4B-3 The partial lighting filling of the lighting element 416 shown in FIG. 4 is optional, such as only realizing Figure 4B-1 and Figure 4B-4 The lighting element 416 may be filled with a blank or fully illuminated portion of the lighting element 416 without partial illumination. Figure 4B-3 The one shown in represents full illumination, while the outer ring of illumination is used to provide additional information, such as quality / adequacy feedback, etc.

[0098] Go to Figure 4C For example, the interior 416a of the circular lighting element 416 of the ventilation system 404 is substantially as Figure 4B-3 4, while the outer ring 416b of the circular lighting element 416 has been illuminated in a different manner (e.g., a different color, lighting quality, etc.). For example, the outer ring 416b may be illuminated in green to indicate that the amount and / or timing of air delivery is within the target range, while the outer ring 416b may be illuminated in yellow to indicate that the amount and / or timing of air delivery does not meet the desired target. The corresponding circle in the prompt graphic 452d of the ventilation feedback display area 450 is illuminated in a different manner (e.g., a different color, lighting quality, etc.). Figure 4B-4 Same as presented in .

[0099] In some implementations, a countdown or other different display is used to prompt the caregiver between ventilation deliveries. Figure 4DIn some implementations, during the pause period prior to the delivery of the next ventilation, the circular lighting element 416 of the ventilation system 404 is strobed or flashed. The strobing or flashing can be performed, for example, as a countdown to the next ventilation. The corresponding circle in the prompt graphic 452e of the ventilation feedback display area 450 presents a numerical value (e.g., the number of seconds remaining until the next ventilation).

[0100] Go to Figure 5A , another example of coordination between a display area 504 of a medical device 502 and an illuminated display 508 of a ventilation system 506 is presented. Figure 5A As shown, the ventilation feedback section 510 of the display area 504 includes a circular prompt graphic 512 of the ventilation feedback section 510, which includes the number "4". Accordingly, the "4" is presented on the illuminated display 508 of the ventilation system 506. For example, the number can be a countdown in seconds until the next air delivery to the patient. In other embodiments, instead of or in addition to the numerical value, a collection of countdown "ticks", "blocks", or gradient bars can gradually change fill, appear, or disappear during the pause period between ventilations.

[0101] Figure 5B Example user interface outputs coordinated between a display area 520 of a medical device and an ECG electrode set 522 are illustrated. For example, the display area 520 illustrates a graphical output associated with an ECG channel set 522a-1. For example, the ECG electrode set 522 can be connected to the medical device via a data transmission cable that includes wires having electrode receiving (e.g., "snap-on") connectors that connect to each ECG electrode 522. In some embodiments, the ECG sensor data corresponding to each individual ECG electrode 522 is logically linked to its corresponding output in the display area 520 such that when a particular ECG channel 522 is selected, the (one or more) ECG electrode(s) 522 and / or connectors leading to the (one or more) ECG electrode(s) 522 corresponding to the ECG signal used to generate the output of the selected graph are illuminated (e.g., light up, flash, change color, etc.) to identify the source of the particular data display. For example, as Figure 5B As illustrated, when ECG channel V1 522g is selected, the connector portion of electrode 522c is illuminated. In this way, if a particular graph appears to produce inconsistent data, errors, or other unexpected graphical output, the caregiver can quickly identify the corresponding (one or more than one) ECG electrode 522 and confirm positioning / adhesion to the patient.

[0102] FIG. 6A to FIG. 6EA sensor independent data interface (SA-DI) cable 600 is illustrated, which includes a first lighting element 604 (e.g., one or more LEDs for indicating a condition) and a second lighting element 606 (e.g., an LED or LCD display). In each figure, the SA-DI cable 600 is coupled to different types of sensors or sensor devices 602, causing the feedback presented via the second lighting element 606 to change accordingly.

[0103] Go to Fig. 6A , the temperature sensor element 602a is coupled to the SA-DI cable 600, and the second lighting element 606 is presenting a digital value corresponding to the temperature (e.g., "32") measured by the temperature sensor element 602a (e.g., a temperature probe, etc.). In some examples, the font (e.g., color, bold, flash) of the digital value and / or the fill in the area behind the font rendering of the digital value can indicate whether the temperature is within an acceptable range for the patient temperature or outside a threshold range for the patient temperature.

[0104] In some implementations, a filled area following the numeric value indicates the therapy mode. For example, during patient cooling, the area following the numeric value may be filled with a cool color (e.g., blue), while during patient warming, the area following the numeric value may be filled with a warm color (e.g., orange or pink).

[0105] Go to Figure 6B , the IBP sensor element 602b is coupled to the SA-DI cable 600, and the second lighting element 606 is presenting a "Z" corresponding to a zeroing process for initializing the transducer of the IBP probe connected to the SA-DI cable 600. In other embodiments, the second lighting element 606 may present a "zero" or other suitable prompt. The "Z" (or "zero", etc.) may indicate a prompt to the caregiver to initiate a zeroing process and / or the Z may be presented during the zeroing process. While the probe is in use, the lighting element 606 may present one or more digital pressure measurements, such as systolic pressure, diastolic pressure, and / or mean pressure, etc. In some examples, the font (e.g., color, bold, flash) of the digital value and / or the fill in the area behind the font rendering of the digital value may indicate whether the pressure is within an acceptable range for the invasive blood pressure measurement or outside a threshold range for the invasive blood pressure measurement.

[0106] Go to Figure 6C, pulse oximetry sensor element 602c is coupled to SA-DI cable 600, and second lighting element 606 is presenting a digital value corresponding to the blood oxygen saturation level (e.g., "97") measured by pulse oximetry sensor element 602c. In some examples, the font (e.g., color, bold, flash) of the digital value and / or the fill in the area behind the font rendering of the digital value can indicate whether the blood oxygen saturation level is within an acceptable range or outside a threshold range.

[0107] Go to Fig.6D , flow sensor element 602d is coupled to SA-DI cable 600, and second lighting element 606 is presenting a set of digital values ​​corresponding to the amount (e.g., "433") and rate (e.g., "10") measured by flow sensor element 602d. The set of digital values ​​is separated by bars so that each digital value is set in a corresponding semicircle of lighting element 606. In some examples, the font (e.g., color, bold, flash) of the digital value and / or the fill within the semicircular area behind the font rendering of the digital value can indicate the sufficiency of the current metric (amount and / or rate). For example, both the upper and lower semicircles can be filled with the same color / pattern (e.g., green, indicating sufficiency of both rate and amount), or the color / pattern of the upper half can be different from the color / pattern of the lower half (e.g., yellow above, indicating an amount just outside the sufficiency range of ventilation amount, and red below, indicating a rate further outside the sufficiency range of ventilation delivery).

[0108] In other embodiments (not illustrated), the upper and lower halves of the display area can decrease in size to present an outer ring surrounding the upper and lower halves of the display area. For example, the outer ring can represent the time until the next ventilation, where the fill portion of the outer ring increases as time gets closer to the next ventilation time. The fill can include a gradient or a single-tone fill that gradually fills around the outer ring (e.g., clockwise or counterclockwise) to present a visual countdown until the next ventilation.

[0109] In further embodiments, the dividers between the digital regions of the lighting element 606 can be used as an indicator of ventilation time. For example, the bar can gradually change color and / or change thickness (increasing or decreasing) to represent the countdown to the next ventilation.

[0110] Go to Fig. 6E, CPR sensor element 602e is coupled to SA-DI cable 600, and second lighting element 606 is presenting a set of digital values ​​corresponding to rate (e.g., "94") and depth (e.g., "1.2") measured by CPR sensor element 602e. The set of digital values ​​is separated by bars such that each digital value is disposed in a corresponding semicircle of lighting element 606. In some examples, the font (e.g., color, bold, flash) of the digital value and / or the fill within the semicircular area behind the font rendering of the digital value can indicate the adequacy of the current metric (rate and / or depth).

[0111] In some embodiments, based on the range of rate and / or depth, the compression rate and / or compression depth are visually represented in at least two separate colors (e.g., by font and / or by fill). For example, the compression rate can be designated as "slow", "sufficient" or "fast" (e.g., orange, green, yellow), and the color markings or other visual indications can be adjusted appropriately. In another example, the compression rate can be designated as "outside the sufficient range" or "within the sufficient range" (e.g., green represents within the target range, and yellow or red represents outside the target range). In a further example, the compression rate can be designated as "far outside the range", "falling outside the range" or "sufficient", and three (e.g., red, yellow, green) indication options or five indication options are used (e.g., so as to visibly distinguish between too slow or too fast).

[0112] In other embodiments, a bar graph or half pie chart corresponding to each numerical value can be filled in corresponding to the adequacy of the current metric. For example, a partially filled graph can represent slower than fully, a filled graph can represent fully, and a filled area (e.g., using red) can represent faster than the maximum target rate. Similarly, turning to compression depth, over-pressing / under-pressing can be handled in a similar manner, or in two different ways (e.g., fully pressing or not pressing; under-pressing, fully pressing or over-pressing, etc.). Visual indications can be applied in a similar manner to that described about compression rate.

[0113] Fig. 7A , Figure 7B-1 and Figure 7B-2 A flow sensor system including an illuminated user interface is illustrated for providing guidance and / or feedback to a caregiver providing ventilation to a patient. The flow sensor system may be used, for example, in Figure 4A , Figure 4B-1 to Figure 4B-4 and / or Figure 5A Used in ventilation systems.

[0114] Go to Fig. 7AIn some implementations, the flow sensor system 700 includes a flow conduit 702 defining an inner lumen 704 that allows gas to pass from a ventilation source (such as a manual ventilation bag or an automatic ventilation system, etc.) through the flow conduit 702 to a patient.

[0115] In some embodiments, the flow conduit 702 is constructed of a first part 706a and a second part 706b molded from a thermoplastic material that are assembled and ultrasonically welded to form the flow conduit 702. The first part 706a may include a first connection portion 708, and the second part 706b may include a second connection portion 710, wherein the flow sensor may be connected to the second connection portion 710. For example, the first connection portion 708 may be configured to couple to a ribbed fitting (e.g., for a ventilator tube or vent), and the second connection portion 710 may be configured to couple to a tapered fitting that slides along its surface (e.g., above or below the surface of the conduit) to form a friction or interference fit. It will be appreciated that the connection portions 708, 710 may have any suitable configuration for establishing a suitable port connection with a tube or conduit.

[0116] In some implementations, the flow sensor system 700 is configured to be placed in communication with a ventilation assembly for delivering gas through the inner cavity 704 of the flow conduit 702. The ventilation assembly may include a manual bag ventilation system and / or may include an automatic ventilation system. Therefore, the first connecting portion 708 on the first part 706a can be configured to have an inner diameter with a larger diameter suitable for accommodating the end of a tube or channel of the ventilation assembly to form a standard female connection. The first connecting portion 708 can also have a ribbed outer diameter to form a standard male connection with a larger tube into which the first connecting portion 708 is inserted. The second connecting portion 710 on the second part 706b can have a smooth outer diameter to form a standard male connection in other tubes or channels of the ventilation assembly.

[0117] In some implementations, the flow sensor system 700 is configured to be connected to a processor of a computing device (e.g., a patient monitor) and / or a processor of a data transmission cable via a cable connector 714. For example, the processor can analyze sensor signals from the flow sensor system 700, derive metrics, and provide feedback to an operator of the flow sensor system 700 regarding the flow rate and / or amount of gas being delivered to the patient. For example, a portion of the feedback can be presented on a housing of a data transmission cable coupled to the cable connector 714 of the flow sensor system. In addition, a portion of the feedback can be presented on a display of a computing system (e.g., a patient monitor). The feedback can be visual, audio, and / or tactile feedback. The feedback can allow the operator to adjust the timing and / or force of actuation of the manual bag ventilation system.

[0118] In some implementations, the flow sensor system 700 includes a cover 724 on a circuit board configured to collect sensor data associated with the flow sensor system 700. As illustrated, the cover 724 is positioned on an upper surface of the flow conduit 702. In some embodiments, both the circuit board and the cover 724 are shaped to correspond to the shape of the upper surface of the flow conduit 702 to fit over the flow conduit 702 and hold the circuit board in place.

[0119] In some implementations, the processor is incorporated into a connector 712 of the flow sensor system 700, which is configured to be removably coupled to the flow conduit 702. For example, when coupled, the connector 712 can place a circuit board and / or a pressure sensor of the flow sensor system 700 in communication with the processor of the connector 712. That is, when the connector 712 is coupled to the flow conduit 702, electrical communication can be established between the pressure sensor, the circuit board, the processor, and other electrical components (e.g., a computing device, a defibrillator, a tablet, a monitor, etc.) to which the cable 714 extends. The outer housing of the connector 712 can include a strain relief housing 722 that surrounds the cable 714 when the cable 714 passes through the strain relief housing 722 to protect the connection between the cable 714 and the processor.

[0120] In some implementations, the illuminated display area 726 of the connector 712 is configured to present at least a portion of feedback related to the flow rate and / or amount of gas being delivered to the patient. The feedback can allow the operator to adjust the timing and / or force of actuation of the manual bag ventilation system. As illustrated, the display area 726 includes a series of lighting elements 728 surrounding the edge of the illuminated display area 726 (e.g., as illustrated, including elements 728a and 728n and spanning therebetween). The display area 726 may also include an illuminated display 730 (e.g., an LCD display, an LED display, etc.) on the surface of the connector 712.

[0121] In some implementations, the illuminated display area 726 is configured to provide visual feedback to the caregiver regarding whether the ET tube has been properly placed. When the tube is determined to be properly placed, the system can activate a green LED at an appropriate location (e.g., along the edge of the connector 712 using at least a portion of the lighting elements 728a-728n, on the surface of the connector 712 using the illuminated display 730, etc.). If a previous ventilation attempt results in a determination that the ET tube is incorrectly placed, the system can activate a red LED of the visual indicator. The visual indicator can also include a series of LEDs configured as a two-color bar graph to indicate the tidal volume of each consecutive ventilation, where the color of the LED bar indicates whether the tube is properly placed (green indicates correct placement; red indicates incorrect placement). Alternatively, separate indicator lights can be provided for airway and breathing to indicate correct ET tube placement and ventilation tidal volume, respectively.

[0122] In some implementations, the connector 712 includes a molded housing or shell that contains the internal assembly of the connector 712, such as a processor, etc. When the connector 712 is installed on the flow conduit 702, the shell can be engaged by snap arms 716a, 716b extending from the upper surface of the flow conduit 702. The shell can include a recess 718 formed therein, and the snap arms 716a, 716b can each include a protrusion 720 formed along its length. The protrusion 720 on the snap arms 716a, 716b can be engaged within the recess 718 on the shell to maintain the engagement between the connector 712 and the snap arms 716a, 716b, while allowing the connector 712 to rotate relative to the flow conduit 702 without disengagement, and allowing the connector 712 to be coupled to the flow conduit 702 from various angular orientations. The snap arms 716a, 716b can be flexible so that they can deflect a suitable amount to allow the connector 712 to be connected to and removed from the flow conduit 702. It can be appreciated that complementary snap arms 716a, 716b and protrusions 720 are not a required aspect of the present disclosure, as the flow conduit 702 and connector 712 can be engaged via any suitable configuration, such as via magnetic coupling, interference fit, etc.

[0123] In some embodiments, when connected to the flow conduit 702, the connector 712 can be rotated about the transverse axis of the flow conduit 702 in a manner similar to a turntable. Fig. 7A , Figure 7B-1 and Figure 7B-2 In the illustrated configuration, the cable 714 extends horizontally relative to the flow conduit 702 along the plane about which the connector 712 rotates. Thus, the feedback presented to the caregiver via the illuminated display 726 (if digital feedback is included) may lack proper orientation relative to the caregiver.

[0124] Go to Figure 7B-1 and Figure 7B-2 In some implementations, the connector 712 includes a dome display attachment 750 that includes one or more lighting elements. For example, the dome display attachment 750 can provide feedback that is visible from multiple directions (e.g., above the dome display attachment 750 or from any side of the dome display attachment 750). In some embodiments, the dome display attachment 750 is built into the connector and electrically connected to the cable 714. In other embodiments, the dome display attachment 750 is attached to the connector 712 via a display attachment 752. For example, the display attachment 752 can deliver power and control signals from the cable 714 via the connector 712.

[0125] Go to Figure 7B-2 , in some implementations, the display attachment 752 is an articulated attachment that is configured to enable the dome display attachment 750 to be moved into a vertical position, thereby exposing a display surface 754. As illustrated, the display surface 754 is presenting the amount (433) and the rate (10) in a digital format. For example, the display surface 754 can be an LED or LCD display. In some embodiments, the display attachment 752 is rotatably attached to the connector 712 so that the face of the display surface 754 can be oriented to point to the caregiver. In some embodiments, the caregiver can rotate the connector 712 to direct the display surface 754 into the field of view.

[0126] return Fig. 7A In other embodiments (not shown), the cable 714 may extend vertically relative to the flow conduit 702. For example, instead of rotating around a two-dimensional plane with a circular range of motion, the connector 712 and flow conduit 702 joint may be configured such that the cable 714 may have a generally hemispherical or dome-shaped range of motion.

[0127] In some implementations, the flow sensor system 700 includes a connector 712 that places the first absolute pressure sensor and the second absolute pressure sensor in electronic communication with the processor. The processor can be configured to receive absolute pressure measurements from the first absolute pressure sensor and the second absolute pressure sensor, and can determine at least one of a flow rate and an amount of gas flowing through the lumen 704 of the flow conduit 702 based on the pressure measurements in the flow conduit 702. The processor can also be configured to generate a signal for outputting the determined flow rate and / or amount of gas flowing through the flow conduit 702, and / or send a feedback signal to adjust the flow of gas flowing through the lumen 704 of the flow conduit 702 based on at least one of the determined flow rate and amount of gas flowing through the lumen 704. In other implementations, the processor can simply store / transmit the signals generated from the pressure sensors to another computing device for further analysis and processing, such as a medical device to which a data transmission cable is connected, etc. In further embodiments, the processor of the flow sensor system 700 may perform some of these calculations (such as determining the flow rate through the catheter 702 based on the signal sent from the pressure sensor (e.g., based on a pre-calibrated pressure lookup table), etc.), and may further perform mathematical integration to obtain the flow rate. An external device (e.g., a tablet, a defibrillator, a patient monitoring device, etc.) may then receive these values ​​of rate and amount and send a feedback signal to the processor, which may be further output in an intuitive manner via an illuminated display for guiding or otherwise encouraging the user to maintain and / or improve the overall quality of resuscitation.

[0128] It will be appreciated that each of the processes for analyzing the measurement signals generated by the pressure sensor(s), outputting calculated values ​​(e.g., flow rate, flow rate, peak inspiratory pressure (PIP), etc.), and providing feedback signals to adjust the manner in which the airflow is provided based on the analysis of the pressure measurement signals can be performed at any suitable portion(s) and location(s) of the entire medical system. For example, each of these steps can be performed at the same location by the same processor (such as a processor located in a cable head or connector of a data transmission cable, etc.). Alternatively, each of these steps can be performed at different locations of the medical system by different processors (e.g., located in a cable head connector, other parts of the flow sensor, a medical device system located further away (such as a defibrillator, monitor, tablet computer, computer, ventilator, etc.). For example, a processor located in a cable head connector can analyze the pressure measurement signals and determine the flow rate and / or amount within the lumen 704 of the flow sensor system 700. As described above, the same processor or other processors (eg, located in a monitor, defibrillator, ventilator, and other suitable processing system) may further output feedback signals to adjust flow parameters (eg, ventilation bagging, auto-ventilation features).

[0129] Fig. 8A and Figure 8B A flow chart of an example method 800 for coordinating caregiver feedback between a computing device having a display and one or more sensor devices connected to a medical device via one or more data transmission cables is illustrated. As described above, the (one or more) data transmission cables may include SS-DI cables and / or SA-DI cables. For example, the method 800 may be performed by Figure 1A and Figure 1B Medical devices 102, Figure 4A Medical device 402 and / or Figure 5A The method 800 is performed by a medical device 502. In some embodiments, portions of the method 800 are performed by a computing device in communication with a medical device, such as a tablet or laptop.

[0130] In some implementations, method 800 begins by determining that CPR has been initiated (801). For example, a medical device such as a patient monitoring and / or treatment device may be configured to receive a CPR signal from a patient such as a patient. Fig. 6E Initial sensor data is obtained by a compression sensor such as compression sensor 602e. In another example, the user can submit an instruction for CPR initiation at the control device. In some examples, the control device can include a portable patient monitoring device, a tablet computing device, or a defibrillator device.

[0131] In some implementations, a press indication is obtained from a press sensor connected to a first data transmission cable (802). For example, the press indication can be provided from the press sensor to a medical device via the first data transmission cable. In addition, the medical device can provide the press indication to a separate computing device (such as a tablet computing device, etc.).

[0132] In some implementations, a compression rate and / or a compression depth are calculated based on the compression indication (804). In some embodiments, the compression sensor data is aggregated, adjusted, or at least partially converted to a compression metric by a processor of the first data transmission cable before being provided to the medical device. In further embodiments, the compression sensor data is aggregated, adjusted, or at least partially converted to a compression metric by a processor of the medical device before being provided to the computing device. In various implementations, the compression rate and / or the compression depth can be calculated at least in part by a processor of the first data transmission cable, a processor of the medical device, and / or a processor of the computer device.

[0133] In some implementations, the compression timing and / or depth information is presented on a display area (806). The display area can be a display area of ​​a medical device and / or a computing device. For example, the compression timing and / or depth information can be displayed as Figure 4A The illustrated manner of presentation includes depth in inches (eg, 1.2) and / or rate in compressions per minute (cpm) (eg, 170).

[0134] In some implementations, a compression timing and / or depth guidance indicator is provided for display on the data transmission cable in coordination with presentation on the display area (808). Figure 4A As illustrated, CPR release timing bar graph 422a is reflected as bar graph 422b on the first lighting element of data transmission cable 420. In addition, metric feedback related to compression depth 424a (e.g., 1.2 inches) and compression rate 426a (e.g., 170 compressions per minute) presented on display 408 is reflected on the second display element of data transmission cable 420 as compression rate 426b and compression depth 424b.

[0135] In some implementations, if the calculated compression rate and / or compression depth is not within the target range (810), the guidance indicator is adjusted to identify that the rate and / or depth is outside the target range (812). For example, flashing lighting, a warning color (e.g., red or yellow) of an LED indicator, a warning symbol in an LCD display, or other indicators can be provided to convey to the caregiver that the therapy delivery is outside the target range.

[0136] Go to Figure 8BIn some implementations, if the ventilation sensor is connected via a second data transmission cable (814), a ventilation indication is obtained from the ventilation sensor (816). The ventilation indication can be provided to the medical device from the ventilation (e.g., airflow) sensor via the second data transmission cable, for example. In addition, the medical device can provide the ventilation indication to a separate computing device (such as a tablet computing device, etc.).

[0137] In some implementations, ventilation rate and / or ventilation volume are calculated based on the ventilation indication (818). In some embodiments, the ventilation sensor data is aggregated, adjusted, or at least partially converted to a ventilation metric by a processor of the second data transmission cable before being provided to the medical device. In further embodiments, the ventilation sensor data is aggregated, adjusted, or at least partially converted to a ventilation metric by a processor of the medical device before being provided to the computing device. In various implementations, the ventilation rate and / or ventilation volume can be calculated at least in part by a processor of the second data transmission cable, a processor of the medical device, and / or a processor of the computer device.

[0138] In some implementations, the ventilation rate and / or ventilation volume is presented on a display area (820). The display area can be a display area of ​​a medical device and / or a computing device. The ventilation rate and / or ventilation volume information can be, for example, Figure 4A The examples are presented in an exemplary manner, including amounts in milliliters (eg, 433) and / or rates in minutes of ventilation (eg, 5).

[0139] In some implementations, ventilation timing and / or volume guidance indicators are provided for display on the second data transmission cable in coordination with the display in the display area and further coordinated with the compression timing (822). Figure 5A As illustrated, the ventilation feedback section 510 of the display area 504 includes a circular prompt graphic 512 of the ventilation feedback section 510, which includes the number "4" (e.g., 4 seconds until the next ventilation). Accordingly, "4" is presented on the illuminated display 508 of the ventilation system 506. Similarly, Figure 4B-1 to Figure 4B-4 An example of displayed feedback 452 reflecting feedback presented on lighting element 416 of ventilation system 404 is illustrated.

[0140] In some implementations, if the calculated ventilation rate and / or the calculated ventilation volume is not within the target range (824), the guidance indicator is adjusted to identify that the rate and / or volume is outside the target range (826). For example, flashing lighting, a warning color (e.g., red or yellow) of an LED indicator, a warning symbol in an LCD display, or other indicators can be provided to convey to the caregiver that therapy delivery is outside the target range.

[0141] In some implementations, if CPR is paused (828), method 800 returns to pending initiation of CPR (802). Otherwise, method 800 returns to obtaining compression indication (802).

[0142] Although method 800 is described according to a particular series of steps, in other embodiments, method 800 includes more or fewer operations. For example, before providing a ventilation timing guidance indicator (822) for display, the timing can be calculated based in part on the tracking of the number of compressions. In addition, in some embodiments, certain steps of method 800 can be performed in a different order and / or in parallel. For example, although described as a series of operations, obtaining a compression indication (802) and obtaining a ventilation indication (816) can occur substantially in real time and in parallel via a first data transmission cable and a second data transmission cable, respectively. In addition, calculating a compression indication (804) and presenting compression rate and / or depth information (806) can occur substantially in parallel and in real time together with calculating ventilation rate and / or volume (820) and presenting ventilation rate and / or volume information (820). Other embodiments of method 800 are possible.

[0143] Fig. 9 A schematic diagram of an example cable circuit system 900 for a data transmission cable is illustrated. The cable circuit system 900 may be included in a housing portion of a data transmission cable, such as Figure 1A and Figure 1B The housing 114 of the data transmission cable 104 or Fig. 7A , Figure 7B-1 and Figure 7B-2 The housing of the connector 712 of the cable circuit system 900, etc. The cable circuit system 900 includes a cable processor 902, a cable memory 904, and a cable patient leakage current isolation device and / or circuit system 906. In some implementations, the cable circuit system 900 includes an analog-to-digital (A / D) converter 908, which is configured to convert an analog signal from at least one sensor in communication with the circuit system 900 into a digital signal for the cable processor 902. For clarity, the A / D converter 908 is shown separately from the cable processor 902, but can be integrated into the cable processor 902.

[0144] In some implementations, the cable patient leakage current isolation device and / or circuit system 906 includes: circuit systems and other hardware and / or physical components that are configured to limit patient leakage current from an attached medical device (such as a Figure 1A and Figure 1B Medical devices 102, Figure 4A Medical device 402 and / or Figure 5AIn the illustrated example, the medical device may be a defibrillator, and the patient may be coupled to defibrillation electrodes and to sensors, which in turn are coupled to the medical device via a data transmission cable including the cable circuit system 900. Further with respect to this example, the defibrillation current (I defibrillation ) follows the current path from the medical device to the defibrillation electrodes, through the patient to the electrodes, and then back to the medical device. There is a potential current path between the defibrillation circuit and the data transmission cable, for example, via stray capacitance between the medical device, the patient, and the sensor, through which the patient leakage current (I leakage ) can reach the patient via the sensor. However, the cable patient leakage current isolation portion 906 in the cable circuit system 900 can be configured to prevent any patient leakage current from reaching the sensor and the patient, thereby providing a protective safety layer built into the data transmission cable.

[0145] In some implementations, the cable patient leakage current isolation portion 906 includes an isolation barrier device, such as a dual capacitor isolation barrier device, a digital isolator device, an optical isolator device, etc. The cable patient leakage current isolation portion 906 can be configured to transmit power signals and communication signals across the isolation barrier. In some examples, the hardware and / or physical components of the cable circuit system 900 can also include conductive and insulating layers and / or coatings coupled to and / or surrounding the cable patient leakage current isolation portion 906.

[0146] In some implementations, the cable patient leakage current isolation section 906 is configured to transmit power unidirectionally across the isolation barrier toward the cable processor 902. When the data transmission cable is coupled to a medical device, the medical device can be a sensor power supply, and power can be provided to the cable processor 902 and the sensor via a port of the medical device and a data transmission cable connected to the port. For example, the data transmission cable can transmit power via at least one conductor, while another conductor is grounded. The cable patient leakage current isolation section 906 can transmit the power transmitted by the data transmission cable from the medical device across the isolation barrier to the cable processor 902 and the sensor in one direction. With this unidirectional power transmission, there is substantially limited or no power transmission from the processor side of the cable patient leakage current isolation section 906 toward the medical device. In an example, the cable patient leakage current isolation section 906 can transmit or transfer 0.1-1 watts of power across the isolation barrier.

[0147] In some embodiments, the cable patient leakage current isolation portion 906 is configured to transmit across the isolation barrier an amount of power specific to the power requirements of the sensor connected to the data transmission cable. For example, an invasive blood pressure sensor may require approximately 0.2 watts, while a flow sensor may require approximately 0.5 watts. Thus, the power transmission capabilities of the cable patient leakage current isolation portion 906 can be customized to the power requirements of the sensor. Thus, the medical device can be configured to apply power in an amount compatible with a variety of sensors that can be connected to one of its data ports.

[0148] In some implementations, the cable patient leakage current isolation portion 906 is configured to transmit communication signals bidirectionally across the isolation barrier. For example, the bidirectional nature of the transmission can enable a medical device to be a source of communication signals and send information to the cable processor 902 and sensors connected to the cable via these signals. Similarly, this bidirectionality can enable the cable processor 902 and / or connected sensors to be a source of communication signals and send information to the medical device via these signals.

[0149] In some implementations, the cable circuit system 900 includes an authentication circuit system 910 for authenticating a data transmission cable with a medical device. For example, the data transmission cable may include at least one authentication cable contact configured to connect to an authentication contact of a data port of the medical device, and the conductors of the data cable may include at least one authentication wire. The authentication circuit system 910 may be configured to receive an authentication / identification (AU / ID) request from the medical device via the at least one authentication cable contact. In addition, the authentication circuit system 910 may be configured to send AU / ID information back to the medical device in response to the received AU / ID request.

[0150] like Fig. 9 As shown, in some implementations, the authentication circuit system 910 includes an integrated encryption engine 912 configured to use an encryption mechanism specific to the medical device (e.g., (one or more) encryption keys, (one or more) encryption algorithms, etc.). For example, the manufacturers of both the medical device and the data transmission cable can provide an encryption key that is compatible with and unique to both the medical device and the data transmission cable for authenticating the data transmission cable. The encryption engine 912 can provide the encrypted AU / ID information 914 to the medical device for authentication of the data transmission cable.

[0151] In some implementations, the cable storage 904 includes stored unencrypted sensor information 916. In the absence of malicious and / or hacker modifications to the data transmission cable, the unencrypted sensor information 916 matches the encrypted AU / ID information 914. The cable storage 904 may also include stored sensor software and / or application programming interface (API) 918 and corresponding software / API information, such as software version number, API version number, update information, supported data protocols and / or sensor data formats, etc. in some examples.

[0152] In various implementations, the sensor software and / or API 918 is stored in the memory 904 at the time of manufacture of the data transfer cable. In some embodiments, the medical device is configured to provide any available updates to the software while the data transfer cable is connected to the medical device. In some embodiments, the sensor data format is transmitted from the data transfer cable to the medical device, and the data format is updated on the medical device while the data transfer cable is connected to the medical device.

[0153] During communication with the data transfer cable, the medical device can receive version and update information for the sensor data format, software, and / or API 918. In such an embodiment, if an update is required, the medical device can instruct the cable processor 902 to enter a download mode. In response, the cable processor 902 can accept or deny the request based on other ongoing activities. Upon acceptance, the medical device can initiate and continue the sensor data format, software, and / or API update to the software and / or API 918.

[0154] In some implementations, the cable circuit system 900 includes a display controller 920 for controlling one or more lighting elements 922. In some examples, the display controller 920 can cause illumination of different colors, fill patterns, strobe or blinking patterns, and / or lighting intensities in response to instructions from the cable processor 902. Different colors, fill patterns, strobe or blinking patterns, and / or lighting intensities can be presented to convey different types of status indicators, warnings, caregiver feedback, and / or alarm states. Additionally, in some embodiments, (one or more) lighting elements 922 are configured to present alphanumeric characters, such as an LED display or an LCD display, etc. In these embodiments, in some examples, the status indicators, warnings, caregiver feedback, and / or alarm states may include alphanumeric messages, such as about FIG. 6A to FIG. 6E Messages presented by various sensors 602 on the lighting element 606, etc.

[0155] In various implementations, the medical device can be a defibrillator, a patient monitor, a defibrillator / monitor, an automated compression device, a therapeutic cooling device, an extracorporeal membrane oxygenation (ECMO) device, a ventilation device, a combination thereof, or other types of medical devices configured to be coupled to one or more than one therapy delivery components to provide therapy to a patient. In an implementation, the medical device can be an integrated therapy delivery / monitoring device within a single housing. The single housing can at least partially surround the therapy delivery component and the monitoring component. In an implementation, the medical device can be a modular therapy delivery / monitoring device, in which a patient therapy component in one unit is communicatively coupled to a patient monitoring unit without a therapy delivery component.

[0156] The medical device may be, for example, a therapeutic medical device capable of delivering a medical treatment. For example, the medical treatment may be an electrotherapy (e.g., defibrillation, cardiac pacing, synchronized cardioversion, diaphragm or phrenic nerve stimulation), and the medical device may be a defibrillator, a defibrillator / monitor, a mechanical ventilator such as ZOLL Z-Vent, and / or other medical devices configured to provide electrotherapy. As another example, the medical treatment may be a chest compression therapy for treating cardiac arrest, and the medical device may be a mechanical chest compression device, such as a belt-based chest compression device or a piston-based chest compression device, etc. As other examples, the medical treatment may be ventilation therapy, therapeutic cooling or other temperature management, invasive hemodynamic support therapy (e.g., extracorporeal membrane oxygenation (ECMO)), etc., and the medical device may be a device configured to provide corresponding treatment. In implementation, the medical device may be one or more combinations of these examples. The therapeutic medical device may include a patient monitoring capability via one or more sensors. These types of medical treatments and devices are examples only and not limitations of the present disclosure.

[0157] Go to Fig.10 , a schematic diagram of an example medical device / data transmission cable system 1000 with a sensor-independent data interface port is shown. The medical device / data transmission cable system 1000 includes a medical device 1002 and a data transmission cable 1004. The medical device 1002 includes a housing 1006, a display 1008, a power control 1010, a new patient control 1040 for indicating operation of the system 1000 for a new patient, and at least one data transmission (e.g., sensor-independent data interface (SA-DI)) port 1012 (e.g., SA-DI ports 1012a and 1012b). Although in Fig.101016a and 1016b, etc. In various implementations, the medical device 1002 may include only one or more SA-DI ports, or a combination of one or more SA-DI ports and one or more sensor-specific DI (SS-DI) ports (such as SS-DI ports 1016a and 1016b, etc.).

[0158] like Fig.10 Schematically illustrated in FIG, SS-DI ports 1016a and 1016b each include a port patient leakage current isolation portion 1018a, 1018b. Data transmission ports 1016a and 1016b are also spaced apart by a distance d>0 for noise reduction and electrical isolation. Data transmission ports 1016a and 1016b may also include physical elements 1014a, 1014 (e.g., such as a conductive material layer, etc.) to reduce electromagnetic interference that causes signal noise. As described above, these features of the SS-DI port increase the weight and volume of the medical device 1002. In contrast, SA-DI ports 1012a and 1012b may exclude (i.e., not include) a port patient leakage current isolation portion. SA-DI ports 1012a, 1012b are configured to be coupled to a data transmission cable compatible with SA-DI ports 1012a, 1012b (e.g., with an electromechanical connector 1042 of a data transmission cable 1004). As illustrated by cable 1004, a compatible data transmission cable includes a cable patient leakage current isolation portion 1018. In addition, the SA-DI ports 1012a and 1012b can be arranged close to each other with a spacing approximately equal to zero. Since these ports do not include a patient leakage current isolation portion 1018, they do not require a noise reduction barrier or physical layer 1014. Port patient leakage current isolation portions, port spacing, and physical noise reduction layers are generally not included on multiple SA-DI ports, which reduces the weight and volume of the medical device 1002. For example, the medical device 1002 can accommodate more sensors using SA-DI ports than using SS-DI ports, and still achieve overall weight and volume reduction. Note that the medical device 1002 can include additional patient leakage current isolation portions 1022 beyond those provided by the data transmission cable 1004.

[0159] In some implementations, the medical device 1002 includes a DI port electronics 1024. One or more components of the DI port electronics 1024 may be physically separate or separable from the medical device electronics (e.g., a processor, memory, and associated electronics and hardware controls for treatment delivery, data acquisition, processing, analysis, communication, and display, etc.). One or more components of the DI port electronics 1024 may be communicatively and / or electronically coupled to the medical device electronics. In some embodiments, the DI port electronics 1024 is integrated into the medical device electronics and / or is a component of the medical device electronics. The DI port electronics 1024 may include a host processor 1026, a host memory 1028, and a state engine 1030. In some embodiments, the state engine 1030 is a part and / or function of the host processor 1026. The host processor 1026 may receive sensor data from the sensor 1032 via the data transmission cable 1004, and may provide the sensor data to the medical device electronics for processing and / or display (e.g., at the physical display 1008). In some embodiments, host memory 1028 includes stored sensor software and / or API 1034 and corresponding software / API information, such as software version number, API version number, update information, and / or supported data protocols in some examples.

[0160] In some implementations, the medical device 1002 is configured as a defibrillator or a patient monitor / defibrillator. In this configuration, the medical device 1002 may include an electrotherapy delivery circuit system 1036 and a defibrillation electrode 1038, which may also be used as an ECG sensor. For example, the electrotherapy delivery circuit system 1036 may include one or more capacitors configured to store electrical energy for a pacing pulse or a defibrillation pulse. The electrotherapy delivery circuit system 1036 may also include resistors, additional capacitors, relays and / or switches, a bridge such as an H-bridge (e.g., including an insulated gate bipolar transistor or IGBT), a voltage measurement component, and / or a current measurement component.

[0161] In some embodiments, the display 1008 is configured to provide at least one visual representation of sensor data received by the medical device 1002 via SA-DI port 1012a and / or 1012b and / or via (one or more than one) SS-DI port 1016a, 1016b. The visual representation can provide data as a graph and / or text data. The visual representation can include waveform data, such as but not limited to ECG, pulse oximetry and / or carbon dioxide tracing. The visual representation can include discrete digital data, such as but not limited to blood pressure (NIBP, IBP), heart rate, instantaneous pulse oximetry value and / or instantaneous carbon dioxide tracing value. In addition or alternatively, the visual representation can include or provide caregiver feedback, such as cardiopulmonary resuscitation (CPR) feedback and / or ventilation feedback. CPR feedback can include, for example, compression depth, compression rate, compression time, compression release and / or perfusion performance. The display 1008 can provide CPR feedback in real time on a compression-by-compression basis. The ventilation feedback may include, for example, gas volume, ventilation rate, ventilation quality, and / or ventilation time. In an implementation, the ventilation feedback may be a bag-valve-mask feedback. The visual representation may also include image data, such as, but not limited to, laryngoscopy and / or ultrasound images. The ultrasound images may include ultrasound images of the patient's tendons, muscles, joints, internal organs, skeletal structures, abdomen, and / or other components of the patient's heart, blood vessels, carotid arteries, and / or cardiovascular system. The visual representation may be part of guiding a medical intervention, such as a biopsy, tissue or fluid sample, and / or other diagnostic or invasive procedure, etc.

[0162] The DI port electronics 1024 may control and process data from the SA-DI ports 1012a, 1012b. The DI port electronics 1024 may further control and process data from the SS-DI ports 1016a, 1016b. Alternatively, the SS-DI ports 1016a, 1016b may not be electrically and / or communicatively connected to the DI port electronics 1024. For example, the medical device electronics may control and process data from the SS-DI ports 1016a, 1016b.

[0163] In some implementations, the DI port electronics 1024 includes a state engine 1030. The DI port state engine 1030, the DI port electronics 1024, and / or the host processor 1026 can manage each SA-DI port 1012a, 1012b independently of one or more other DI ports 1012a, 1012b. The DI port state engine 1030 can manage the state of the SA-DI ports 1012a, 1012b.

[0164] In some implementations, the data transmission cable 1004 compatible with the SA-DI ports 1012a, 1012b includes a flexible cable having a conductor disposed within a continuous insulating sheath. The conductor may include a single strand and / or multiple strands of one or more conductive materials. The cable 1004 may be fixedly fastened to a first electromechanical connector 1044 at a first end of the cable 1004, and fixedly fastened to a second electromechanical connector 1042 at a second end of the cable 1004.

[0165] In some implementations, the first electromechanical connector 1044 includes a housing 1046 and an electrical mating piece 1048 (e.g., a first electrical mating piece) disposed within the housing 1046 at an open end of the housing away from the cable. In other words, the cable is connected to the housing 1046 at a first end of the housing 1046, and the electrical mating piece 1048 for the sensor 1032 is disposed in a second, different end of the housing 1046. The electrical mating piece 1048 can be configured to be removably coupled to the sensor 1032 (e.g., coupled to an electrical connector associated with the sensor 1032). For example, the electrical mating piece 1048 can provide an electrical coupling between one or more contacts associated with the sensor 1032 and one or more contacts associated with the data transmission cable 1004. In some examples, the mating attachment of the electrical mating piece 1048 and the electrical connector 1044 can include a pin / socket combination, a plug / jack combination, or a card edge / spring contact combination.

[0166] In some implementations, the first electromechanical connector 1044 includes a data interface circuit system disposed within the housing 1046. The data interface circuit system can be electrically coupled to the electrical mating piece 1048 through one or more electrical contacts, and can be electrically coupled to the conductors of the cable 1004. The data interface circuit system can include a cable processor 1050, a cable memory 1052, and a cable patient leakage current isolation portion 1020. In some embodiments, the data interface circuit system includes an analog-to-digital (A / D) converter circuit configured to convert an analog signal from the sensor 1032 into a digital signal for the cable processor 1050. The A / D converter can be integrated into the cable processor 1050.

[0167] In some implementations, the cable patient leakage current isolation section 1020 includes an isolation device and / or circuit system and other hardware and / or physical components configured to limit the flow of patient leakage current from the medical device 1002 to the patient via the sensor 1032. In particular, for high voltage electrotherapy, leakage current isolation may be beneficial for safety reasons. The cable patient leakage current isolation section 1020 may include an isolation barrier device, such as a dual capacitor isolation barrier device, a digital isolator device, an optical isolator device, etc. The cable patient leakage current isolation section 1020 may be configured to transmit power signals and communication signals across the isolation barrier.

[0168] In some implementations, the cable patient leakage current isolation portion 1020 is configured to transmit power unidirectionally across the isolation barrier toward the cable processor 1050. When the data transmission cable 1004 is coupled to the medical device 1002 via the SA-DI port 1012a or 1012b, the medical device 1002 can be a sensor power supply for the sensor 1032 and can provide power to the cable processor 1050.

[0169] In some implementations, the data transmission cable 1004 includes a cable display controller 1054 (such as Fig. 9 The cable display controller 1054 is configured to control the illumination of one or more cable lighting elements 1056. As described herein, the lighting elements 1056 can be positioned at various locations on the cable, cable housing, and / or connectors to the sensor 1032 and / or data interface ports 1012a, 1012b, and / or 1018a, 1018b. In some embodiments, the cable display controller 1054 and / or the cable processor 1050 are configured to present one or more sensor-independent status indicators, such as a cable connection status indicator, a cable authentication status indicator, and / or a sensor connection status indicator in some examples. In addition, the cable display controller 1054 and / or the cable processor 1050 are configured in some embodiments to present one or more sensor-specific status indicators, such as a sensor reading outside a target range condition in some examples, (one or more) caregiver feedback indicators, and / or (one or more) caregiver guidance / prompt indicators, etc. Certain status indicators may be controlled by the medical device 1002 (eg, by the host processor 1026). For example, upon selecting a portion of the display 1008 dedicated to the data transfer cable 1004, an identification condition may be presented via the cable lighting element(s) 1056.

[0170] Go to Fig.11, a schematic diagram illustrates an example medical device 1100 with a removable sensor hub 1102. The removable sensor hub 1102 can be coupled to the interior or exterior of a medical device housing 1104. In some embodiments, the medical device housing 1104 of the medical device 1100 includes a medical device display 1106 (e.g., a first display), a communication interface 1108 (e.g., a first communication interface), a processor 1110 (e.g., a first processor), a memory 1112 (e.g., a first memory), and associated circuitry. The processor 1110 and the memory 1112 can be communicatively coupled to the display 1106 and the communication interface 1108.

[0171] In some implementations, the housing 1104 includes a sensor hub connector 1114. In various implementations, the sensor hub connector 1114 can be disposed within the housing 1104 (e.g., as illustrated) or can be disposed outside the housing 1104 (e.g., on the exterior of the housing 1104). The sensor hub connector(s) 1114 disposed within the housing 1104 can, for example, form a receptacle configured to receive the sensor hub 1102 and retain the sensor hub 1102 within the housing 1104. The receptacle can also be configured to release the sensor hub 1102 for removal from the medical device 1100. The sensor hub connector(s) 1114 disposed on the exterior of the medical device 1100 can include one or more of a bracket, a clip, a clamp, a magnet, a receptacle, etc. configured to secure the sensor hub 1102 to the exterior of the housing 1104. The sensor hub 1102 can include one or more mating mechanisms configured to be removably coupled to the sensor hub connector 1114. In the illustrative example, the mating mechanism can be a profile on the sensor hub 1102.

[0172] In some implementations, the sensor hub connector 1114 can enable a wired electrical and / or communicative coupling between the sensor hub 1102 and the medical device 1100 via one or more contacts. Sensor hub contacts 1130b (e.g., one or more first electrical contacts) can be disposed on the sensor hub 1102, and medical device contacts 1130a (e.g., one or more second electrical contacts) can be disposed on the medical device 1100. The sensor hub connector 1114 can hold the sensor hub 1102 in a position where the contacts contact each other.

[0173] In some embodiments, the sensor hub 1102 and the medical device 1100 communicate with each other via a wired connection when the sensor hub 1102 and the medical device 1100 are physically coupled and / or decoupled. In some embodiments, the sensor hub 1102 is configured to be communicatively coupled to one or more remote computing devices via a network connection. The remote computing devices may include servers and other devices communicatively coupled via a server over a network, such as personal computers, laptops, tablets, mobile devices, and / or other medical devices. In this way, the sensor hub 1102 can enable telemedicine and remote data viewing, analysis, storage, and / or sharing.

[0174] The sensor hub 1102 includes a housing 1116 (e.g., a second housing or a sensor hub housing). The housing 1116 may include one or more mating mechanisms 1118 configured to removably couple the sensor hub 1102 to the sensor hub connector 1114. In some implementations, the sensor hub 1102 includes at least one DI port 1120 coupled to the housing 1116. The at least one DI port 1120 may include a SS-DI port (e.g., Fig.10 SS-DI ports 1016a, 1016b) and / or SA-DI ports (e.g., Fig.10 At least one DI port 1120 may be configured to couple to a data transmission cable (eg, Fig.10 data transmission cable 1004) and sensors (e.g., Fig.10 sensor 1032) and is configured to receive sensor data.

[0175] In some implementations, the sensor hub 1102 includes a sensor hub processor 1122 (e.g., a second processor), a sensor hub memory 1124 (e.g., a second memory), and a sensor hub communication interface 1126 (e.g., a second communication interface). At least one DI port 1120 can be communicatively coupled to the sensor hub processor 1122. The sensor hub processor 1122 can be configured to receive sensor data via the at least one DI port 1120 and send the sensor data to the sensor hub communication interface 1126.

[0176] In some implementations, the sensor hub processor 1122 is configured to store sensor data in a sensor hub memory 1124. The sensor hub 1102 may include at least one universal serial bus (USB) port 1134. The sensor hub 1102 may include a sensor hub power supply 1128. For example, the sensor hub power supply 1128 may include one or more batteries configured to provide power to the sensor hub 1102 independently of power provided to the sensor hub 1102 by the medical device 1100. In the illustrative example, when the sensor hub 1102 is physically connected to the medical device 1100 using the sensor hub connector 1114 (e.g., via the electrical contacts 1130a, 1130b), the one or more batteries can be recharged using power from the medical device 1100.

[0177] In some implementations, the sensor hub communication interface 1126 is configured to communicatively couple to the medical device communication interface 1108 and send the sensor data to the medical device processor 1110 via the medical device communication interface 1108. In some embodiments, the medical device processor 1110 is configured to control the medical device display 1106 to display a visual representation (e.g., a first visual representation) of the sensor data obtained via the sensor hub 1102 to a user.

[0178] In some implementations, the sensor hub communication interface 1126 and the medical device communication interface 1108 are configured to communicate with each other via wired and / or wireless communication coupling. When the sensor hub 1102 is physically held by the sensor hub connector 1114, the communication interfaces 1108 and 1126 can communicate via a wired coupling (e.g., via contacts 1130a and 1130b). When the sensor hub 1102 is decoupled from the sensor hub connector 1114, the communication interfaces 1108 and 1126 can communicate via a wireless coupling. The sensor hub connector 1114 and the mating mechanism 1118 can be configured to physically couple the medical device 1100 and the sensor hub 1102 so that the contacts 1130a and 1130b provide electrical and / or communication connectivity.

[0179] In some implementations, the medical device 1100 includes multiple sensor hubs (e.g., multiple sensor hub connectors inside and / or outside the housing 1104). Each sensor hub may include a sensor hardware control 1132. The sensor hardware control 1132 can be customized for a specific sensor type or a set of sensor types. For example, each sensor hub in two or more sensor hubs may include a sensor hardware control customized for one or more specific sensor types, which is configured to be coupled to a specific sensor hub via a DI port (such as DI port 1120, etc.). The number of DI ports and the type of sensor associated with the DI port can vary from sensor hub to sensor hub. The processor 1110 of the medical device 1100 can be configured to provide a visual representation of data from all sensor hubs in one or more sensor hubs coupled to the medical device 1100 via the display 1106 of the medical device 1100.
