Description

Technical Field

[0001] The utility model relates to the field of medical devices, and in particular to a universal (multi-purpose) dual-mode adapter kit adapted to different medical monitors. More specifically, the utility model relates to a separate kit for providing an adapter between a digital output physiological parameter sensor and different, for example, universal medical monitors, and a medical monitor comprising such a kit. Background Art

[0002] This design is a conversion-adaptation module for connecting digital output sensors for monitoring physiological parameters such as intracranial pressure, intracranial temperature, brain tissue oxygen partial pressure, body temperature, blood oxygen, blood pressure, blood sugar, etc. to patient monitors. At present, there are many brands of monitors for monitoring human physiological parameters, and these brands of monitors are often matched with their corresponding probes. Due to the different definitions and types of interfaces and pins, it is actually impossible to match a variety of different monitors with the same probe, and it is not interchangeable. This is very inconvenient in actual use. For example, when different patients choose different probe brands, the hospital needs to be equipped with a monitor that matches it in order to use it normally. Therefore, the hospital must purchase a matching monitor dedicated to the probe, which greatly increases the hospital's use cost. In addition, when preparing for surgery for patients who have selected different probes, it is necessary to place monitors of different brands in a crowded operating room, and frequently change monitors of different brands, which is inconvenient for doctors to use.

[0003] In order to make the probe adaptable and connected with monitors of different brands, it is necessary to invent a conversion-adaptation module. This device can accept the digital signal output by the physiological parameter sensor probe, output voltage analog signal after passing through the internal conversion circuit, and the analog signal is connected to the monitor through an adapted custom cable, so that the same probe can be adapted to multiple different monitors.

[0004] CN117017256A discloses an intracranial pressure monitor using an open intraventricular catheter method, including a switch cable library that matches the intracranial pressure sensor end of each brand, a universal signal acquisition and sensor end power supply module, a computer and an intracranial pressure monitoring program running thereon; its universal signal acquisition and sensor end power supply module, the computer and the intracranial pressure monitoring program running thereon can also be combined into an embedded instrument as a whole, realizing the conditioning, acquisition, calculation, display and storage of intracranial pressure signals, and at the same time, the sensor end is powered by a switch cable that matches the intracranial pressure sensor end of each brand. This monitor can maximize the sharing of the intracranial pressure monitor body, so that the hospital does not need to be equipped with various other brands of intracranial pressure monitoring instruments, reducing the equipment cost of the hospital and reducing the time for intracranial surgery preparation. However, CN117017256A is designed to be a dedicated intracranial pressure monitor as a whole, and its purpose is to match different intracranial pressure sensor probes.

[0005] US20140024956A1 discloses a transducer interface system / method that allows conversion from analog sensor input to a standardized analog output interface. In some preferred embodiments, the system / method allows a fiber optic pressure sensor to be connected to a standard patient monitoring monitor (PCM) system using a standardized Wheatstone bridge analog interface input. In this case, the Wheatstone bridge detection output is defined by the modulation of the bridge element value by the excitation from the PCM and the regulated output of the analog pressure sensor. The use of analog-to-digital analog conversion in the sensor interface allows PCM devices with analog Wheatstone bridge inputs to be retrofitted with advanced patient monitoring sensors without the need for special modifications to the baseline PCM data collection framework. The method disclosed in US20140024956A1 includes a technique for connecting any type / number of analog transducers to a traditional PCM system without the need for hardware / software modifications to the PCM system. One of the main concepts of US20140024956A1 is to use analog-to-digital analog conversion of analog sensor values ​​in the transducer interface to compensate for the analog sensor signal. In addition, another concept of the invention is to use a PCM system to match any type / number of analog transducers, rather than vice versa.

[0006] Currently, there is no separate switching device on the market that is suitable for switching and matching functions and signals between digital output sensor probes and different medical monitors.

[0007] In view of the above, the art urgently needs improved switching concepts and designs to overcome or improve the above technical defects and achieve corresponding and more beneficial technical effects.

[0008] The information included in this background section of the present specification, including any references cited herein and any description or discussion thereof, is included for technical reference purposes only and is not to be construed as subject matter that will limit the scope of the present invention. Utility Model Content

[0009] The utility model provides a separate kit equipment and operation / use method for providing switching between a digital output physiological parameter sensor and different, for example, universal medical monitors, which has at least the configuration and function of a converter and an adapter. One of the purposes of the utility model is to provide a universal dual-mode switching kit for providing switching between a digital output physiological parameter sensor and different medical monitors, so as to solve the problem that the monitor and different digital output physiological probes need to be adapted to each other, so the hospital needs to be equipped with a variety of monitors with different configurations / types. With the help of the utility model, it is possible to use the same probe to be compatible with medical monitors of various configurations / types, and the adaptation work can be done wirelessly and wired, which can facilitate medical staff to switch and match according to needs, greatly reducing the cost of hospital use, and greatly improving the convenience, user-friendliness and reliability of operation and use by medical staff.

Figure 3 It is a schematic diagram showing the internal circuit configuration of the conversion-adaptation module of the universal dual-mode adapter kit according to an embodiment of the utility model.

[0043] like Figure 1A-1B and Figure 2 As shown, a schematic diagram of the configuration and operation of a universal dual-mode adapter kit for providing adapter between a digital output physiological parameter sensor 1 (probe 1) and different medical monitors 5 according to an embodiment of the utility model is disclosed. This universal dual-mode adapter kit that can adapt to different medical monitors may include a conversion-adaptation module 2. The conversion-adaptation module 2 is configured with: a digital signal input interface 21 suitable for docking (wired / physical connection) with the probe 1 of the digital output physiological parameter; a microcontroller 22, a DAC digital-to-analog conversion circuit 23, a signal conditioning circuit 24, a differential signal generating circuit 25 (and a digital potentiometer 26) that is communicatively connected to the microcontroller 22, and is used to convert the sensor digital signal from the probe 1 into an analog signal suitable for receiving and processing by the medical monitor 5; and an analog signal output interface 27. The probe 1 can process / convert the signal output by the sensor into a digital signal that can be processed and recognized by the conversion-adaptation module 2 of the universal dual-mode adapter kit.

[0044] The conversion-adaptation module 2 collects and reads the digital signal output by the probe 1 through, for example, the signal received by the digital signal input interface 21 or the wireless signal sent by the wireless digital transmission module 4 from the probe 1, and performs signal processing inside the conversion-adaptation module 2. The digital signal collected by the probe 1, for example, about various physiological parameter indicators of the human body, is calculated and controlled by the microcontroller 22 to generate a differential signal and / or an analog signal of resistance through the DAC (digital-to-analog conversion) circuit 23, the signal conditioning circuit 24, the differential signal generating circuit 25, the digital potentiometer 26, etc. The analog signal is transmitted to the monitor 5 through the analog signal output interface 27 using the monitor adapter cable 3.

[0045] The conversion-adaptation module 2 may also be provided with a probe zeroing button 28, a mode switching button 30 and an LED indicator light 29 which may be configured as a dual color, for example. The probe zeroing button 28 is configured to zero the output of the probe 1 before implanting the probe 1 into a human body for surgery, and the mode switching button 30 may be configured to switch the three output modes of the conversion-adaptation module, and repeated pressing may alternately switch between the three modes of zero standard reference signal output mode, standard reference signal output mode and monitoring mode. The mode switching button 30 may be, for example but not limited to, in the form of a gear switching button, such as a graded button or a translation sliding button, which has three gears, corresponding to the zero standard reference signal output mode, the standard reference signal output mode and the monitoring mode, respectively, so that the gears corresponding to the three modes may be easily switched by simple button operation. The LED indicator light 29 which is configured to emit dual colors (e.g., blue and green) may indicate the current state to facilitate the operation of the doctor / nurse.

[0046] The conversion and switching module 2 can receive the digital output signal of the probe 1 in two ways: wired mode and wireless mode (as described below with the help of the wireless digital transmission module 4). Among them, the wireless mode connection is more convenient and flexible, and in clinical use, it can provide great convenience and flexibility in patient transfer and monitoring equipment movement.

[0047] according to Figure 1A-1B The universal dual-mode adapter kit of the illustrated embodiment may further include a wireless digital transmission module 4, which is configured to be suitable for realizing wireless signal transmission between the probe 1 and the conversion-adaptation module 2. The wireless digital transmission module 4 can transmit the signal from the probe 1 to the conversion-adaptation module 2 in a wireless manner. The wireless digital transmission module 4 may be configured with a battery inside, which can power the module 4 itself and the probe 1.

[0048] according to Figure 1A-1B The universal dual-mode adapter kit of the illustrated embodiment may also include a universal monitor adapter cable 3, whose input end is configured to be suitable for communication connection with the analog signal output interface 27 of the conversion-adaptation module 2, and whose output end is configured to adapt to interfaces of at least two different types of medical monitors 5. The monitor adapter cable 3 is a cable for connecting between the conversion-adaptation module 2 and the monitor 5, and has multiple different types of connectors, which can be adapted to monitors 5 of various configurations / types. The corresponding cable connector can be selected according to the configuration / type of the monitor.

[0049] For example, the monitor adapter cable 3 can be configured to adapt to at least one of the following monitor end interfaces of the common invasive pressure measurement cables on the market: 14-pin interface, such as provided by Nihon Kohden Co., Ltd., mainly compatible with monitor brands such as NihonKohden; 11-pin interface, such as provided by GE, mainly compatible with monitor brands such as Marquette and GE; 10-pin interface, such as provided by Siemens, mainly compatible with monitor brands such as Siemens; 12-pin interface, such as provided by Mindray and Philips, mainly compatible with monitor brands under Mindray and Philips.

[0050] The monitor adapter cable 3 can also be configured to adapt to at least one of the following interfaces of the monitor end of the temperature measurement cables commonly available on the market: a 6.35 mm male plug; a 2-pin temperature probe interface, such as those provided by Mindray and Philips.

[0051] The monitor adapter cable 3 can transmit the analog signal of the conversion-adaptation module 2 to the monitor 5; at the same time, for example, the monitor 5 can also power the conversion-adaptation module 2 through the cable 3; and the conversion-adaptation module 2 can also power the probe 1 (for example, a bougie) in a wired mode (as described below). Due to the different configurations / types of the connected monitors 5, the corresponding interface types of the monitors 5 may be different, and different monitor connection cable interfaces that match them need to be used. Therefore, an example of a monitor adapter cable 3 is to include multiple cables, each cable having a different interface that is compatible with the monitor. Another example of a monitor adapter cable 3 is to use a cable that is equipped with multiple different interfaces to match different types of monitor interfaces.

[0052] The Universal Dual Mode Adapter Kit is configured to operate in the following two modes.

[0053] (1) Wired mode. In the wired mode, the probe 1 and the digital signal input interface 21 of the conversion-adaptation module 2 can be connected through, for example, a probe extension cable 6 ( Figure 1A ) is connected by wired communication, or the probe 1 and the conversion-adaptation module 2 are directly connected ( Figure 1B ) to achieve wired communication and data transmission between the two, such as Figure 1A and Figure 1B The two modes are shown in the figure. The conversion-adaptation module 2 collects relevant digital signals about various physiological parameter indicators of the human body from the probe 1 through its digital signal input interface 21 .

[0054] (2) Wireless mode. When the wireless method is used, the wireless digital transmission module 4 is additionally used to perform wireless data transmission. In the wireless mode, the probe 1 is first physically docked with the wireless digital transmission module 4 to form a communicative connection, and the wireless digital transmission module 4 and the conversion-adaptation module 2 are configured to automatically connect wirelessly, for example, but not limited to, at a communication frequency of 2.4 GHz through Bluetooth, WiFi wireless communication, or through wireless communication technologies such as Zigbee, to achieve automatic or manual wireless connection.

[0055] An example of how to use the universal dual-mode adapter kit in wired mode is as follows:

[0056] (a) Use the monitor adapter cable 3 to connect the front-end signal output interface 27 of the conversion-adaptation module 2 to, for example, the invasive pressure measurement channel of the monitor 5. At this time, the LED indicator 29 on the conversion-adaptation module 2 turns green and stays on.

[0057] (b) Insert the uncalibrated probe 1 into the input end of the probe extension cable 6, and insert the output end of the probe extension cable 6 into the conversion-adaptation module 2. At this time, the LED indicator 29 changes from a solid green state to a flashing green state.

[0058] (c) Place the sensing end of the probe 1 horizontally in the air or in a container such as a shallow pool filled with sterile water or sterile saline for zeroing. Press the probe zeroing button 28 of the conversion-adaptation module 2 for about 8 seconds. After the zeroing button is pressed, the LED indicator 29 turns blue and flashes. When the LED indicator 29 stops flashing blue and turns blue and always on, release the zeroing button 28. The LED indicator 29 turns green and flashes, and the zeroing of the probe 1 is completed. At this time, the probe 1 must be used only with the conversion-adaptation module 2 for zeroing. Note that the probe 1 zeroing step must be performed before the probe 1 is implanted in the human body, because the zeroing of the probe 1 after implantation will cause inaccurate readings of some physiological parameters such as pressure. The example of placing the sensing end of the probe 1 horizontally in the air for zeroing operation is preferred, which is simple, convenient, fast and easy to operate, and has good user-friendliness, especially in typical practical application occasions of the utility model, such as hospitals, wards, ICU monitoring rooms and other environmental conditions.

[0059] (d) After the probe 1 is successfully zeroed, the monitor 5 needs to be zeroed. The mode switching key 30 is pressed for the first time. At this time, the conversion-adaptation module 2 enters the zero standard reference signal output mode. At this time, the LED indicator 29 turns blue and is always on. The conversion-adaptation module 2 outputs a zero standard reference analog signal (for example, a pressure signal of 0 mmHg when measuring invasive blood pressure or intracranial pressure) to the monitor. The monitor 5 is zeroed according to, for example, the monitor instruction manual, the user manual, etc. At this time, the monitor 5 displays the zero standard reference value.

[0060] (e) Press the mode switch key 30 for the second time. At this time, the conversion-adaptation module 2 enters the standard reference signal output mode, the LED indicator 29 is always blue, and the conversion-adaptation module 2 outputs a standard reference analog signal (for example, a pressure signal of 100 mmHg is output when measuring invasive blood pressure or intracranial pressure) to the monitor 5. At this time, the monitor 5 displays the standard reference value. If the reading on the monitor 5 is inconsistent with the standard reference value, adjust the parameters of the monitor 5 (for example, but not limited to the gain of the monitor 5, etc.) according to the monitor instruction manual, user manual, etc. until the standard reference value is displayed.

[0061] (f) Press the mode switch key 30 for the third time, the conversion-adaptation module 2 enters the monitoring mode, and the LED indicator 29 turns green and flashes. In this monitoring mode, the probe 1 will collect the various physiological parameters currently measured by the patient in real time. At this time, the probe 1 can be implanted in the patient's body, and the conversion-adaptation module 2 will receive and convert the digital signal from the probe 1 in real time, output the corresponding analog signal, and transmit the analog signal to the monitor 5 to achieve the purpose of measurement and monitoring.

[0062] One or more of steps (d), (e), and (f) may be repeated at any time to ensure that the monitor 5 can be correctly calibrated. That is, if the monitor 5 needs to be zeroed again in the monitoring mode, the above steps (d), (e), and (f) may be repeated.

[0063] An example of how to use the universal dual-mode adapter kit in wireless mode is as follows:

[0064] (1) Use the monitor adapter cable 3 to connect the front-end signal output interface 27 of the conversion-adaptation module 2 to, for example, the invasive pressure measurement channel of the monitor 5. At this time, the LED indicator on the conversion-adaptation module 2 turns green and stays on, indicating that the probe 1 is not connected.

[0065] (2) Physically connect the uncalibrated probe 1 to the wireless digital transmission module 4 (for example, insert the probe 1 into the wireless digital transmission module 4). The wireless digital transmission module 4 will automatically establish a wireless communication connection with the conversion-adaptation module 2. After the connection is successful, the LED indicator 29 changes from a solid green state to a flashing green state, indicating that the wireless connection is successful.

[0066] (3) Place the sensing end of the probe 1 horizontally in the air or in a container such as a shallow pool filled with sterile water or sterile saline for zeroing. Press the probe zeroing button 28 of the conversion-adaptation module 2 for about 8 seconds. After the zeroing button is pressed, the LED indicator 29 turns to a blue flashing state. When the LED indicator 29 stops flashing blue and turns to a blue steady state, release the zeroing button 28. The LED indicator 29 turns to a green flashing state, and the zeroing of the probe 1 is completed. At this time, the probe 1 must only be used with the conversion-adaptation module 2 for zeroing. Note that the probe 1 zeroing step must be performed before the probe 1 is implanted in the human body, because the zeroing of the probe 1 after implantation will cause inaccurate readings of some physiological parameters such as pressure. The example of placing the sensing end of the probe 1 horizontally in the air for zeroing operation is preferred, which is simple, convenient, fast and easy to operate, and has good user-friendliness, especially in typical practical application occasions of the utility model, such as hospitals, wards, ICU monitoring rooms and other environmental conditions.

[0067] (4) After the probe 1 is successfully zeroed, the monitor 5 needs to be zeroed. Press the mode switch key 30 for the first time. At this time, the conversion-adaptation module 2 enters the zero standard reference signal output mode. At this time, the LED indicator 29 turns blue and lights up. The conversion-adaptation module 2 outputs the zero standard reference signal (for example, a pressure signal of 0 mmHg when measuring invasive blood pressure or intracranial pressure) to the monitor 5. The monitor 5 is zeroed according to the monitor instruction manual, user manual, etc. At this time, the monitor 5 displays the zero standard reference value.

[0068] (5) Press the mode switch key 30 for the second time. At this time, the conversion-adapter module 2 enters the standard reference signal output mode. The LED indicator 29 is always blue. The conversion-adapter module 2 outputs a standard reference signal (for example, a pressure signal of 100 mmHg is output when measuring invasive blood pressure or intracranial pressure) to the monitor 5. At this time, the monitor 5 displays the standard reference value. If the reading on the monitor 5 is inconsistent with the standard reference value, adjust the parameters of the monitor 5 according to the monitor instruction manual, user manual, etc. until the standard reference value is displayed.

[0069] (6) Press the mode switch key 30 for the third time, and the conversion-adaptation module 2 enters the monitoring mode. The LED indicator 29 turns green and flashes. In this monitoring mode, the probe 1 will collect the various physiological parameters currently measured by the patient in real time. At this time, the probe 1 can be implanted in the patient's body, and the conversion-adaptation module 2 will receive and convert the digital signal from the probe 1 in real time in a wireless manner, output the corresponding analog signal, and transmit the analog signal to the monitor 5 to achieve the purpose of measurement and monitoring.

[0070] One or more of steps (4), (5), and (6) may be repeated at any time to ensure that the monitor 5 can be correctly calibrated. That is, if the monitor 5 needs to be zeroed again in the monitoring mode, the above steps (4), (5), and (6) may be repeated.

[0071] The following takes the example of implementing the probe as an intracranial monitoring (ICM) bougie and adapting the universal dual-mode adapter kit of the utility model to an ICM monitor to further describe the implementation methods and solutions of the utility model.

[0072] Taking the monitoring of the intracranial pressure and intracranial temperature of a patient through an ICM bougie as an example, a complete intracranial pressure monitoring usually mainly includes two parts: an intracranial pressure monitoring probe and an intracranial pressure monitor paired with it. An example of probe 1 may be an FPC (flexible circuit board)-sensor integrated bougie, which includes a pressure sensor and a temperature sensor for measuring the intracranial pressure and temperature of the patient. An example of the FPC-sensor integrated bougie may be the bougie and bougie assembly disclosed in the PCT international application "Artificial Intelligence Assisted Intracranial Monitoring System and Bougie Assembly" with international application number PCT / CN2023 / 108432 filed on July 20, 2023, and the relevant contents of the PCT international application are incorporated into this application by reference, just as discussed in this application.

[0073] Usually, traditionally, intracranial pressure measurement is to implant an ICM bougie into the patient's ventricle or brain parenchyma, and the intracranial pressure monitoring probe 1 transmits analog signals of intracranial pressure, temperature, etc. through the probe catheter and the adapter cable to the matching dedicated intracranial pressure monitor for signal processing, and intuitively displays intracranial pressure data and waveforms on the monitor screen. At present, for example, the measurement sensitivity of a multi-parameter monitor with an invasive pressure measurement function is generally 5μV / V / mmHg. Therefore, according to the utility model, a universal dual-mode adapter kit is provided, and with the help of its conversion-adaptation module 2, the digital signal of the current pressure output by the ICM bougie 1 can be converted to a differential analog voltage signal through the DAC circuit 23 (i.e., digital-to-analog conversion circuit), the signal conditioning circuit 24, the differential signal generating circuit 25 and other circuits inside the conversion-adaptation module. The sensitivity of the analog voltage signal can be consistent with the sensitivity of the monitor receiving the signal, so that intracranial pressure monitoring can be easily realized. Usually, the NTC resistance value can be measured to calculate and measure the intracranial temperature of the patient. According to the universal dual-mode adapter kit provided by the utility model, the microcontroller 22 can obtain the intracranial temperature currently measured by the ICM bougie by reading the digital signal output by the ICM bougie, and the microcontroller / single-chip microcomputer controls the digital potentiometer (for example Figure 3The digital potentiometer 26) circuit shown generates a resistance value corresponding to the NTC resistor-temperature meter of the monitor, thereby realizing intracranial temperature measurement. The conversion-adaptation module 2 is an adapter module applicable to a digital output probe 1 such as an ICM bougie, which can realize digital to analog conversion.
