Description

Technical Field

[0001] This application relates to the technical field of physiological signal acquisition devices and systems, specifically to a fusion multi-physiological signal sensing device, detection device, and multi-physiological signal detection method that connects to a single port and a monitor. Background Technology

[0002] In traditional physiological signal acquisition, because different types of physiological signals have different detection principles, corresponding physiological signal sensors or acquisition devices are usually set up separately for each type of physiological signal. For example, in an independent ECG signal acquisition device, all electrode connections for measuring ECG are installed in the ECG cable. Similarly, in an independent POS signal acquisition device, all electrode connections for measuring POS are installed in the POS cable. And in an independent body temperature signal acquisition device, electrode connections for measuring body temperature are installed in the body temperature cable.

[0003] This design results in a wide variety of accessories for multi-parameter monitoring equipment, making storage extremely cumbersome. Measuring three physiological parameters requires three different accessories; this means that multiple accessories must be stored separately, increasing not only the difficulty and workload of storage but also requiring the fixing of multiple different types of signal acquisition devices to different parts of the body for use.

[0004] For multi-parameter monitoring equipment, in order to accommodate different accessories, various physiological parameter measurement cable interfaces need to be set on the multi-parameter monitoring equipment. For example, the outer shell of the multi-parameter monitoring equipment needs to be equipped with blood oxygen cable interfaces, electrocardiogram cable interfaces and body temperature cable interfaces respectively. The setting of multiple interfaces increases the cost of equipment design and implementation.

[0005] For electrocardiogram (ECG) measurements, at least three electrode connection lines are required for the ECG cable. Therefore, in a standalone ECG signal acquisition device, at least three independent electrical connection lines need to be branched off from the main ECG cable for electrical connection with different ECG electrodes. Since the ECG electrodes are located in different positions, the lengths of these three independent electrical connection lines also have corresponding requirements. This results in more branches in the ECG cable and makes storage more troublesome.

[0006] like Figure 21 The diagram shows the connection of various physiological signal sensors in existing technologies for multi-parameter monitoring. Figure 21 As shown, a separate blood oxygen signal sensor is set up for blood oxygen measurement; a separate body temperature signal sensor is set up for body temperature measurement; a separate electrocardiogram (ECG) signal sensor is set up for ECG measurement; and three interfaces are set up on the side of the multi-parameter monitoring device to connect to the three independent physiological signal sensors, with each interface connecting to one of the physiological signal sensors.

[0007] like Figure 21 As shown, in order to measure electrocardiogram (ECG) signals, the ECG signal sensing device is equipped with multiple ECG electrode connection points. These multiple ECG electrode connection points need to be placed in different parts of the human body, which means that the ECG signal sensing device must have multiple cables of different lengths and sufficient length. One end of these cables is connected to the ECG electrodes attached to the surface of the human body, and the other end is collected by a hub and then fed into a multi-parameter monitoring device for signal processing.

[0008] In the prior art, there are devices that integrate cables for measuring multiple physiological signals. For example, in a multi-parameter cable splitter (CN201898306U), multiple independent ECG cables are connected to the main body of a multi-parameter monitor after being transferred through the multi-parameter cable splitter.

[0009] In this integration, when using a multi-parameter monitor, multiple independent ECG signal acquisition devices are still required at the patient end: ECG electrodes and cables are connected; pulse oximeter probes are connected to pulse oximeter cables; and temperature probes are connected to temperature cables. The electrode connections of the ECG cables cannot be integrated with the pulse oximeter or temperature probes. For the subjects being monitored by the multi-parameter monitoring equipment, the ECG electrodes, pulse oximeter probes, and temperature probes still need to be fixed separately at different locations.

[0010] For the monitored patient, this often involves multiple ECG electrodes attached to the chest, a pulse oximeter clipped to the finger, and a temperature electrode fixed in a specific location. Having electrodes attached and connected in multiple different locations is extremely uncomfortable for the patient. Even slight movement can cause the multiple cables to pull against each other, affecting their connections and making the measurement process very unpleasant. Furthermore, the individual ECG signal connection lines connected to the multiple ECG electrodes are easily pulled during use and are more prone to damage than the cables at the back of the hub.

[0011] For nurses, this also requires locating suitable body parts on the patient to attach each physiological parameter acquisition device. ECG electrodes are typically attached to the chest and limbs; pulse oximeter probes are usually clamped or attached to the extremities. Connecting multiple sites and different signal acquisition devices not only makes the patient's experience during measurement very unpleasant but also increases the workload for nurses. Attaching or connecting electrodes to multiple different sites is uncomfortable and inefficient. Multiple individual ECG signal cables in contact with the body also increases the amount of disinfection work when changing users.

[0012] To reduce the inconvenience caused by cables from multiple signal acquisition devices in the design, use, and storage of multi-parameter monitoring equipment, and especially to improve patient experience and nurse efficiency, a revolutionary solution is urgently needed. However, since the advent of monitoring equipment, everyone seems to have become accustomed to or adapted to this method of setting up separate physiological signal acquisition devices, and has not found a solution that can truly improve patient experience and nurse efficiency.

[0013] To address the aforementioned technical problems, the applicant proposed a solution in patent application number CN2021112193876, entitled "Multi-physiological signal sensing and detection device and acquisition method and monitor," such as... Figure 22 As shown. Although it can solve the problems in the existing technology well, the connection with the monitor is still not streamlined enough. How to further improve the connection efficiency with the monitor and provide a more efficient and convenient multi-physiological signal sensing and detection device is the technical problem to be solved by this application. Summary of the Invention

[0022] It is possible that the electrical connection wires in the main cable include electrical connection wire group A and electrical connection wire group B; the A connection wire group is surrounded by an A shielding layer; the electrical connection wires in the A connection wire group are used for electrical connection of photoelectric signals; the B connection wire group is surrounded by a B shielding layer; the electrical connection wires in the B connection wire group are used for electrical connection of any one or more of the following: electrocardiogram signal, body temperature signal, or respiratory signal.

[0025] It can be that port A is a plug-in port used for connecting to an external monitor; port B is a plug-in port used for connecting to a probe assembly.

[0026] Yes, the probe assembly can be a multi-parameter fusion probe assembly; the multi-parameter fusion probe assembly includes any one of the following: a 2-parameter fusion probe assembly, a 3-parameter fusion probe assembly, and a 4-parameter fusion probe assembly; the 2-parameter fusion probe assembly includes sensors corresponding to any two of the following parameters: ECG, blood oxygen, body temperature, and respiration; the 3-parameter fusion probe assembly includes sensors corresponding to any three of the following parameters: ECG, blood oxygen, body temperature, and respiration; the 4-parameter fusion probe assembly includes sensors corresponding to all four parameters: ECG, blood oxygen, body temperature, and respiration.

[0030] The technical solution of this application to solve the above problems can also be a multi-physiological signal parameter detection device, used for multi-physiological signal parameter detection, based on the above-mentioned multi-physiological signal sensing device.

[0031] It can also include a signal processing module; the signal processing module includes a blood oxygen signal processing module, an electrocardiogram (ECG) signal processing module, a temperature signal processing module, and a respiratory signal processing module; the photoelectric signal connection line in the main cable is electrically connected to the input terminal of the blood oxygen signal processing module through the A connection port; the ECG signal connection line in the main cable is electrically connected to the input terminal of the ECG signal processing module through the A connection port; the temperature signal connection line in the main cable is electrically connected to the input terminal of the temperature signal processing module through the A connection port; the respiratory signal connection line in the main cable is electrically connected to the input terminal of the respiratory signal processing module through the A connection port.

[0032] The technical solution of this application to solve the above problems can also be a multi-physiological signal detection method, based on the above-mentioned multi-physiological signal sensing device.

[0033] One of the beneficial effects of this application is that the connection between the single-port multi-physiological signal sensing device and the monitor or other host is simplified to a single port, which facilitates connection and allows users to complete multi-parameter measurements with a single connection, greatly improving measurement efficiency.

[0034] One of the beneficial effects of this application is that the multi-parameter fusion probe assembly integrates the acquisition of multiple physiological signals. With just two multi-parameter fusion probe assemblies, it is possible to simultaneously acquire any two or more of the four physiological signals: electrocardiogram, blood oxygen, body temperature, and respiration.

[0035] One of the beneficial effects of this application is that, in practice, one end of the main cable is directly connected to the patient with two multi-parameter fusion probe assemblies, which are similar to two "blood oxygen probes". By clamping or attaching them to the patient's measurement site, four physiological signals, namely electrocardiogram, blood oxygen, body temperature and respiration, can be measured simultaneously.

[0036] One of the beneficial effects of this application is that, in practice, the main cable connects to the monitor via a single A-connector port, simplifying the interface and reducing accessory costs. Previously, ECG cables and pulse oximeter sensors required separate fabrication, increasing the cost of the physical hardware. Furthermore, existing ECG cables required at least three sub-cables to be combined into a single cable, which were prone to damage due to the limited number of electrical connections and frequent operation. Even the solution in CN2021112193876 was not simple enough, still requiring two cables. In contrast, the solution in this application combines all ECG signal connections, pulse oximeter signal connections, body temperature signal connections, and respiratory signal connections into a single cable, resulting in lower manufacturing costs and significantly improved overall reliability.

[0037] One of the beneficial effects of this application is that the multiple electrical connection lines within the main cable are grouped and shielded to ensure that various physiological signals do not interfere with each other during transmission. The number of signal lines in different grouped connection lines varies and can be set according to the required parameters. For example, there are at least 2 ECG signal connection lines; at least 2 photoelectric signal connection lines; at least 1 respiratory signal connection line; and at least 1 body temperature signal connection line.

[0038] One of the beneficial effects of this application is that the B-connection port on the main cable, connected to a probe assembly, further enhances the scalability of the multi-physiological signal sensing device. In practice, it facilitates backward compatibility. If complete multi-parameter physiological signal acquisition is required, a probe assembly can be connected to the B-connection port. If only blood oxygen and body temperature signals, or blood oxygen and respiration signals, or body temperature and respiration signals, are needed, the B-connection port does not require a probe assembly; a single probe assembly on the main cable can acquire any two or three of the blood oxygen, body temperature, and respiration signals. In principle, only ECG signal acquisition requires two probe assemblies; other signals can be integrated into a single probe assembly. Therefore, the B-connection port in this application provides convenience for flexible selection of multiple parameters. It can also save resources in applications where ECG monitoring is not required.

[0039] One of the beneficial effects of this application is that the inclusion of a Type-C port on the main cable further enhances scalability. When multi-point measurements are required, expansion is easier; moreover, expansion does not involve expanding the monitor's connection ports, but only the main cable, offering greater flexibility. Of course, more Type-C ports can be added for more point measurements, such as expanding to 4, 5, or 6 Type-C ports for multi-lead ECG measurements and multi-point acquisition of blood oxygen, body temperature, and respiratory signals.

[0040] One of the beneficial effects of this application is that the inclusion of B1 and B2 connection ports on the main cable further enhances scalability and configuration flexibility, allowing for more flexible selection or combination of probe assemblies. With only one B connection port, the probe assembly connected to the main cable is mandatory; therefore, the measurable parameters of that probe assembly determine the lower limit of the measurement capability of the multi-physiological signal sensing device. However, with two B1 and B2 connection ports, this limitation is eliminated, allowing for the connection of different probe assemblies through the two B connection ports, enabling flexible selection. Furthermore, the number of B connection ports can be expanded further, providing even more flexible options.

[0041] One of the advantages of this application is that both the A and B connection ports are plug-in ports, which are convenient to plug in and out, and have good usability.

[0042] One of the benefits of this application is that the multi-parameter fusion port and multi-parameter fusion probe assembly provide more options, making it easier to combine various parameters to suit different application scenarios.

[0043] One of the advantages of this application is that it is applicable to both clamp-on and patch-type probes, and has a wide range of applications.

[0044] One of the beneficial effects of this application is that the multi-physiological signal parameter detection device based on the multi-physiological signal sensing device of this application can acquire multiple signals at once through efficient and simple connection, resulting in higher signal acquisition efficiency.

[0045] One of the beneficial effects of this application is that, with the help of two probes, any combination of four signals, namely electrocardiogram, blood oxygen, body temperature and respiration, can be acquired simultaneously. At most, four physiological signals can be acquired with the help of two sensing components. It can also acquire two respiratory signals with different measurement principles at the same time, which can be mutually verified to ensure more reliable respiratory detection.

[0112] Figures 13 to 18 The embodiment is Figure 1 The specific implementation method. Figure 19 The embodiment is Figure 2 Specific implementation methods. For example... Figure 20 In one embodiment, one ECG signal connection line can be used as a ground line or a drive line to obtain the basic electrical signal on the body surface; the remaining ECG signal connection lines are electrically connected to each ECG electrode to obtain the ECG signal on the body surface at the corresponding location.

[0113] A method for acquiring multiple physiological signals, based on the aforementioned multiple physiological signal sensing device, wherein the multiple physiological signal sensing device includes at least two multi-parameter fusion probe assemblies. The method includes the following steps: Step A: Acquiring a body temperature signal from each of the at least two multi-parameter fusion probe assemblies; Step C: Acquiring a respiratory signal from each of the at least two multi-parameter fusion probe assemblies; Step D: Selecting any one of the multi-parameter fusion probe assemblies to acquire a blood oxygen acquisition photoelectric signal; Step B: Acquiring a surface electrocardiogram signal from each of the at least two multi-parameter fusion probe assemblies; Steps A, B, C, and D are not in any particular order.

[0114] Step E: Calculate the ECG signal and ECG parameters using the two surface ECG signals obtained in Step B; Step F: Calculate the blood oxygenation parameters using the blood oxygenation photoelectric signal obtained in Step D; Step J: Calculate the body temperature parameters using the body temperature obtained in Step A; Step J: Calculate the respiratory signal and respiratory parameters using the pressure or acceleration signal obtained in Step C. Steps E, F, J, and K are not in any particular order.

[0115] Step B further includes steps B1 and B2; Step B1: acquiring multiple surface electrocardiogram (ECG) signals from the two multi-parameter fusion probe assemblies respectively; Step B2: selecting any one of the multiple surface ECG signals acquired from each multi-parameter fusion probe assembly as the surface ECG signal output by that multi-parameter fusion probe assembly; or in Step B2, performing differential or weighted operations on the multiple surface ECG signals acquired from each multi-parameter fusion probe assembly, and using the signal obtained from the differential or weighted operations as the surface ECG signal output by that multi-parameter fusion probe assembly. Before or after step B, step G is also included: the step of transmitting a driving signal to the body surface; in step G, the external driving signal is transmitted to the body surface through the ECG signal connection line and the ECG electrode connected to it in any one of the multi-parameter fusion probe assemblies.

[0116] The method also includes step H: acquiring a driving signal; in step H: using the two surface electrocardiogram (ECG) signals acquired in step B as the ECG signals for the left and right upper limbs, respectively; and calculating an ECG signal using the ECG signals for the left and right upper limbs; simultaneously, acquiring a driving signal using the ECG signals for the left and right upper limbs; the driving signal acquired in step H is used as the driving signal delivered to the body surface in step G. Step E also includes step E1: calculating a respiratory signal using at least two surface ECG signals acquired in step B.

[0117] One of the beneficial effects of this application is that multiple ECG signal connection lines are set in a sensing component, and each probe is equipped with at least multiple ECG electrodes, enabling multi-point sampling; this ensures the reliability of ECG signal acquisition, that is, multi-point sampling ensures that ECG signals from the body surface can be acquired; at the same time, more raw multi-point body surface signals are obtained for subsequent ECG signal calculation, providing more raw signals for subsequent ECG parameter calculation, and signal quality screening can be performed from the raw signals to obtain higher quality ECG signals.

[0118] A sensing component has multiple ECG signal connection lines, and one of these ECG signal connection lines is used as a ground wire or a drive wire to acquire the basic electrical signal of the body surface. When used as a ground wire, it provides the basic signal level for the entire ECG signal measurement. When used as a drive wire, it can set the potential of the entire ECG signal to a suitable position. With the help of the ground wire or the drive wire, a higher quality ECG signal can be acquired.

[0119] Multiple electrocardiogram (ECG) signal lines are incorporated into a single sensing component. These ECG signal lines can be multiplexed and used as body temperature signal lines. A corresponding probe includes a body temperature signal acquisition sensor connector. The body temperature signal lines and the acquisition connector are electrically connected to acquire the body surface temperature signal. This allows for the acquisition of three physiological signals using only two sensing components.

[0120] By using two ECG electrodes and their ECG signal connection lines set in two probes, respiratory signals can be acquired simultaneously with ECG signals. This allows for the acquisition of four physiological signals using two sensing components, as well as the simultaneous acquisition of respiratory signals based on two different measurement principles. This enables cross-verification and ensures more reliable respiratory detection.

[0121] The above are merely embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of the application specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
