Description

Technical Field

[0001] The present invention relates to the technical field of physiological signal transmission and acquisition devices and systems, and in particular to a fusion multi-physiological signal sensing device, a detection device and a multi-physiological signal acquisition method. Background Art

[0002] In existing physiological signal acquisition technologies, separate physiological signal sensors or devices are typically installed for different types of physiological signals. All electrode connection lines for measuring ECG are installed within the ECG cable of an independent ECG signal acquisition device. All electrode connection lines for measuring blood oxygen are installed within the blood oxygen cable of an independent blood oxygen signal acquisition device. And all electrode connection lines for measuring body temperature are installed within the body temperature cable of an independent body temperature signal acquisition device.

[0003] This design results in a multi-parameter monitoring device with a wide variety of accessories, making storage extremely cumbersome. Measuring three physiological parameters requires three different accessories, which not only increases the difficulty and workload of storing multiple accessories, but also requires attaching multiple different types of signal acquisition devices to different parts of the body.

[0004] For multi-parameter monitoring equipment, in order to accommodate different accessories, it is necessary to set up cable interfaces for measuring various physiological parameters on the multi-parameter monitoring equipment. For example, a blood oxygen cable interface, an electrocardiogram cable interface, and a body temperature cable interface must be set up on the shell of the multi-parameter monitoring equipment respectively. The setting of multiple interfaces increases the cost of equipment design and implementation.

[0005] For ECG measurement, the ECG cable requires at least three electrode connection lines. Therefore, in a separate ECG signal acquisition device, at least three independent electrical connection lines need to be separated from the main ECG cable for electrical connection to different ECG electrodes. Due to the different positions of the ECG electrodes, the lengths of these three independent electrical connection lines also have corresponding requirements. This results in many branches in the ECG cable, making storage more troublesome.

[0006] like Figure 1 As shown in the figure, the connection diagram of various physiological signal sensors in the prior art for multi-parameter monitoring. Figure 1 As shown, for blood oxygen measurement, an independent blood oxygen signal sensing device is set up; for body temperature measurement, an independent body temperature signal sensing device is set up; for electrocardiogram measurement, an independent electrocardiogram signal sensing device is set up; in order to connect with three independent physiological signal sensing devices, three interfaces are set up on the side of the multi-parameter monitoring device, and the three interfaces are connected to a physiological signal sensing device respectively.

[0007] like Figure 1As shown, in order to measure ECG signals, the ECG signal sensing device is provided with multiple ECG electrode connection points, and the multiple ECG electrode connection points need to be set 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 aggregated through the hub and then enters the multi-parameter monitoring device through the cable for signal processing.

[0008] In the prior art, there are devices that integrate cables for measuring multiple physiological signals, such as a multi-parameter cable splitter (CN201898306U), in which 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 such an integrated system, when using a multi-parameter monitor, multiple independent ECG signal acquisition devices are still required on the patient side: ECG electrodes connected to ECG cables, a blood oxygen sensor connected to a blood oxygen sensor cable, and a temperature sensor connected to a temperature sensor cable. The electrode connection end of the ECG cable cannot be integrated with the blood oxygen sensor or temperature sensor. For patients monitored by multi-parameter monitoring equipment, the ECG electrodes, blood oxygen sensor, and temperature sensor still need to be fixed in different locations.

[0010] For monitored patients, multiple ECG electrodes are often attached to their chests, blood oxygen sensors are clipped to their fingers, and temperature electrodes are fixed in specific locations. Having these electrodes attached or connected in multiple locations is extremely uncomfortable for the patient. The slightest movement can cause the multiple cables to pull against each other, affecting their connection status, making the measurement experience very difficult for the patient. Furthermore, the individual ECG signal cables connecting to the multiple ECG electrodes are easily pulled during use and are more susceptible to damage than the cables connected to the hub.

[0011] Nurses also need to find appropriate body parts for each patient to attach each physiological parameter collection device. ECG electrodes are usually attached to the chest and limbs; blood oxygen probes are usually clamped or attached to the extremities of the body. Connecting multiple parts to different signal collection devices not only makes the patient's experience during the measurement process very poor, but also increases the workload of nurses to fix these multiple signal collection devices. Fixing or attaching electrodes and connecting them in multiple different parts is uncomfortable and inefficient. Multiple single ECG signal connection lines come into contact with the human body, which also increases the workload of disinfection 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 the 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 the method of independently configuring physiological signal acquisition devices, and no solution has been found that can truly improve and enhance the patient experience and nurse efficiency.

[0038] Compared with the existing technology, one of the beneficial effects of the present application is that it integrates the acquisition of ECG signals and the acquisition of blood oxygen signals. Without the need for complex multi-head ECG cables, the acquisition of two physiological signals, ECG and blood oxygen, can be completed simultaneously with only two sensor components.

[0039] The second beneficial effect of the present application is manifested in reality, that is, by clamping or sticking two blood oxygen probes on the patient's measured part, two physiological signals of ECG and blood oxygen and their related parameters can be obtained at the same time. The solution of the present application is the result of a reverse revolutionary thinking; it can rescue the entire physiological parameter detection accessories from their respective independent quagmire. It greatly simplifies the interface complexity between the user end and the patient, and greatly improves the patient's test experience. In general physiological monitoring scenarios, there is no need to stick multiple ECG electrodes and connect different ECG cables to the electrodes in sequence. Instead, it is only necessary to connect two or three "blood oxygen probes" to complete the acquisition of blood oxygen and ECG signals at the same time.

[0040] The third beneficial effect of the present application is reflected in reality in that it simplifies the interface between various physiological parameter accessories and monitors; since at least two sensing components are needed in the present application to complete the acquisition of multiple physiological signals and parameters, the interface between the physiological parameter accessories and the host such as the monitor becomes simpler. At the same time, the cost of accessories is also saved; the original ECG cable needed to be made independently, and the blood oxygen sensor also needed to be made independently, and the cost of the physical hardware was higher. In addition, the ECG cable in the prior art requires at least three sub-cables to be aggregated into one ECG cable. Since the sub-cables have few electrical connecting wires and are frequently operated, they are very easy to be damaged. In the technical solution of the present application, there is no need for sub-cables, and all ECG signal connecting wires and blood oxygen signal connecting wires can be aggregated into one cable, which not only reduces the production cost but also greatly improves the overall reliability.

[0041] Compared with the prior art, the fourth beneficial effect of the present application is that multiple ECG signal connection lines are provided in a sensing component, and each probe is provided with at least multiple ECG signal acquisition electrode connectors, which can perform multi-point sampling; the reliability of obtaining ECG signals is ensured, that is, multi-point sampling ensures that surface electrical signals can be obtained; at the same time, more original multi-point surface signals are obtained for subsequent ECG signal calculations, and more original signals are provided for subsequent ECG parameter calculations, and signal quality screening can be performed from the original signals to obtain higher quality ECG signals.

[0042] Compared with the prior art, the fifth beneficial effect of the present application is that multiple ECG signal connection lines are provided in a sensing component, and one of the ECG signal connection lines is used as a ground line or a driving line to obtain basic surface electrical signals; when used as a ground line, it provides a basic signal level for the entire ECG signal measurement; when used as a driving line, it can set the potential of the entire ECG signal to a suitable position, and with the help of the ground line or the driving line, a higher quality ECG signal can be obtained.

[0043] Compared with the prior art, the sixth beneficial effect of this application is that multiple ECG signal connection lines are provided in a single sensor assembly, wherein the ECG signal connection lines can be reused as body temperature signal connection lines. The corresponding probe is provided with a body temperature signal acquisition sensor connector. The body temperature signal connection lines and the body temperature signal acquisition connector are electrically connected to obtain the body surface temperature electrical signal. In this way, three physiological signals can be acquired using two sensor assemblies.

[0044] Compared with the prior art, the seventh beneficial effect of the present application is that, with the help of two ECG signal acquisition electrode connectors and ECG signal connecting lines respectively provided in the two probes, the respiratory signal can be obtained at the same time as the ECG signal is acquired, so that the four physiological signals can be acquired with the help of two sensing components.

[0054] The content of this application is further described in detail below with reference to the accompanying drawings.

[0055] like Figure 2 and 3 The illustrated embodiment of a multi-physiological signal sensing device includes at least two sensing assemblies: a first sensing assembly 301 and a second sensing assembly 302. Each sensing assembly includes an electrical connection wire set 220 and a probe 100, with the electrical connection wire set 220 electrically connected to the probe 100. At least one of the two sensing assemblies includes a blood oxygen signal connection wire 221 in the electrical connection wire set. The number of blood oxygen signal connection wires 221 may be one or two.

[0056] like Figure 2 As shown, the electrical connection wire set 220 is encased in the cable body 210. This set of electrical connection wires 220 includes one ECG signal connection wire 222 and two blood oxygen signal connection wires 221. The probe 100, electrical connection wire set 220, and cable body 210 together form a complete standard accessory for physiological parameter sensing.

[0057] like Figures 2 to 3 In the illustrated embodiment of a multi-physiological signal sensing device, at least one probe is provided with a blood oxygen signal acquisition sensor connector. The blood oxygen signal acquisition sensor connector includes an SPO2 light source and an SPO2 detector. The SPO2 light source and the SPO2 detector can each be electrically connected to a blood oxygen signal connection line 221. The blood oxygen signal acquisition sensor connector can also be a sensor connector that integrates the SPO2 light source and the SPO2 detector, and is electrically connected to a blood oxygen signal connection line. The blood oxygen signal acquisition sensor connector is electrically connected to a blood oxygen signal connection line in each group of electrical connection lines to achieve optical driving and optical detection.

[0058] like Figures 2 to 3 In the illustrated embodiment of a multi-physiological signal sensing device, there are two sensor assemblies 300, namely a first sensor assembly 301 and a second sensor assembly 302. In the first sensor assembly 301 and the second sensor assembly 302, each electrical connection line group 220 is provided with at least one ECG signal connection line 222, and each probe is provided with at least one ECG signal acquisition electrode connector. The ECG signal acquisition electrode connector can be an ECG electrode sheet or other forms of ECG electrode; the ECG signal acquisition electrode connector is used to directly contact the surface of the human body being measured; the ECG signal acquisition electrode connector in each probe is electrically connected to the ECG signal connection line in each electrical connection line group. That is, one ECG signal connection line 222 is connected to one ECG signal acquisition electrode connector.

[0059] like Figure 5 The illustrated embodiment includes two sensor assemblies: a first sensor assembly 301 and a second sensor assembly 302. The first sensor assembly 301 includes a first sensor assembly probe 301100 and a first sensor assembly cable body 301210; the second sensor assembly 302 includes a second sensor assembly probe 302100 and a second sensor assembly cable body 302210. This allows the two sensor assemblies to simultaneously measure two physiological parameters: blood oxygen and electrocardiogram (ECG). Because each sensor assembly is equipped with one or more ECG signal acquisition electrode connectors and their electrical connection cables, and both sensor assemblies are equipped with blood oxygen signal acquisition sensor connectors and their electrical connection cables, the combined use of the two sensor assemblies allows for the acquisition of blood oxygen signals at two locations, as well as the acquisition of body surface potentials at different points. ECG signals can then be obtained by calculating the body surface potentials at these points.

[0060] In this application, blood oxygen and ECG signal acquisition electrode connectors and electrical connection lines are cleverly set in each sensor component, so that the connection interface between the external sensor and the patient is simplified; it only needs to make contact with the sensor at two points with the subject to be measured to complete the collection of multiple physiological parameters. There is no need to apply multiple ECG electrodes to the chest, and thus there is no need to connect each ECG electrode to an ECG cable separately, and there is no need to use a multi-head ECG cable. Only two blood oxygen sensors similar to those in the prior art need to be set up to complete the collection and detection of two physiological signals at the same time.

[0061] like Figure 6In the illustrated embodiment of a multi-physiological signal sensing device, each probe 100 is provided with two ECG signal acquisition electrode connectors; the two ECG signal acquisition electrode connectors in the probe 100 are electrically connected to two ECG signal connection lines 222 in the corresponding set of electrical connection lines. The SPO2 light source and SPO2 detector can each be electrically connected to a blood oxygen signal connection line 221.

[0062] In some embodiments not shown in the accompanying drawings, one of the two ECG signal acquisition electrode connectors in the probe 100 is electrically connected to an ECG signal connection line in a corresponding set of electrical connection lines. The control instruction for selecting one of the two ECG signal acquisition electrode connectors can be obtained by the main control module; a selection switch for the selection control can also be provided in the main control module.

[0063] like Figure 7 In the illustrated embodiment, each probe is provided with an ECG signal acquisition electrode connector, a body temperature signal acquisition electrode connector, and two ECG signal connection lines 222; an ECG signal acquisition electrode connector, i.e., an ECG electrode, is electrically connected to an ECG signal connection line 222; and a body temperature signal acquisition electrode connector, i.e., a body temperature electrode, is electrically connected to another ECG signal connection line 222. Each set of electrical connection lines is also provided with an SPO2 light source and an SPO2 detector, which can be electrically connected to a blood oxygen signal connection line 221, respectively. In this embodiment, the two sensor components cooperate to complete the acquisition of at least three physiological signals, i.e., ECG, blood oxygen, and body temperature. Of course, when necessary, the two sensor components can cooperate to utilize the respiratory signal acquired by the two sensor components.

[0064] like Figure 8 In the illustrated embodiment, each probe is provided with three ECG signal acquisition electrode connectors; each set of electrical connection lines is provided with three ECG signal connection lines 222; each ECG signal acquisition electrode connector in the probe is electrically connected to each ECG signal connection line in the corresponding set of electrical connection lines. Each set of electrical connection lines is also provided with an SPO2 light source and an SPO2 detector, each of which can be electrically connected to a blood oxygen signal connection line 221; each probe is provided with two ECG signal acquisition electrode connectors, a body temperature signal acquisition electrode connector, an ECG signal acquisition electrode connector (i.e., an ECG electrode) electrically connected to an ECG signal connection line 222; and a body temperature signal acquisition electrode connector (i.e., a body temperature electrode) electrically connected to another ECG signal connection line 222. Each set of electrical connection lines is also provided with an SPO2 light source and an SPO2 detector, each of which can be electrically connected to a blood oxygen signal connection line 221.

[0065] like Figure 9 In the embodiment shown, and Figure 8 The difference of the embodiment shown in Figure 9In this embodiment, the SPO2 light source and SPO2 detector are integrated into a single connection terminal, which only needs to be electrically connected to a single blood oxygen signal connection line 221. This blood oxygen signal connection line 221 can be time-shared and multiplexed to complete blood oxygen signal acquisition. In this embodiment, each set of electrical connection lines includes three ECG signal connection lines 222, each of which can be connected to an ECG signal acquisition electrode connector, i.e., an ECG electrode. The remaining blood oxygen signal connection line 221 can be electrically connected to a body temperature signal acquisition electrode connector, i.e., a body temperature electrode, to acquire a body temperature signal.

[0066] In some embodiments not shown in the accompanying drawings, each probe is provided with three or more ECG signal acquisition electrode connectors; each set of electrical connection lines is provided with three or more ECG signal connection lines; each ECG signal acquisition electrode connector in the probe is electrically connected to each ECG signal connection line in the corresponding set of electrical connection lines. One of the multiple ECG signal connection lines in each set of electrical connection lines is electrically connected to a signal input terminal of the differential operation module.

[0067] In some embodiments not shown in the accompanying drawings, one ECG signal connection line in the electrical connection line group of any one sensor assembly is used as a ground line or a drive line to obtain basic body surface electrical signals; the remaining ECG signal connection lines in the electrical connection line group are electrically connected to one ECG signal acquisition electrode connector to obtain body surface electrical signals at corresponding locations; the ECG signal connection lines in the electrical connection line group of the remaining sensor assemblies are electrically connected to one ECG signal acquisition electrode connector to obtain body surface electrical signals at corresponding locations. The remaining sensor assemblies refer to one or more sensor assemblies in which the ECG signal connection lines are not selected as ground lines or drive lines; that is, in two sensor assemblies, only one ECG signal connection line in one of the sensor assemblies is required to be used as a ground line or a drive line, and the other ECG signal connection lines in the same sensor assembly can be used to obtain ECG signals at other points; all ECG signal connection lines in the other sensor assembly paired with or in the same group as the sensor assembly can be used to obtain ECG signals at other points.

[0068] In some embodiments not shown in the accompanying drawings, among the two or more ECG signal connection lines in the electrical connection line group of a sensor component, any one ECG signal connection line is used as a ground line or a drive line, and the remaining ECG signal connection lines in the electrical connection line group are used to obtain the surface electrical signals of the corresponding positions. The ECG signal connection lines in the remaining electrical connection line group do not need to be provided with ground lines or drive lines for ECG signal acquisition. In this case, one ECG signal connection line in the electrical connection line group of the remaining sensor component can be used as a body temperature signal connection line, and a body temperature signal acquisition sensor connector is provided in the corresponding probe. The body temperature signal connection line and the body temperature signal acquisition connector are electrically connected to obtain the body surface temperature electrical signal. The other ECG signal connection lines in the remaining electrical connection line group can also be used to obtain the surface electrical signals of the corresponding positions. In this way, in form, the three physiological parameters of blood oxygen, ECG and body temperature can be measured simultaneously with the help of two sensor components.

[0069] like Figure 4 In the illustrated embodiment, the probe is a clamp-type probe, comprising an upper probe clamping portion 510 and a lower probe clamping portion 520; the upper probe clamping portion 510 and the lower probe clamping portion 520 are movably clamped and connected to clamp the subject's body; the surfaces of the upper probe clamping portion 510 and the lower probe clamping portion 520 are respectively provided with an ECG signal acquisition electrode connector ECG-1 and an ECG signal acquisition electrode connector ECG-2. The blood oxygen signal acquisition sensor connector comprises a light-emitting component and a detection component that are arranged opposite to each other; the light-emitting component is arranged on the upper probe clamping portion or the lower probe clamping portion; correspondingly, the detection component is arranged on the lower probe clamping portion or the upper probe clamping portion opposite to the light-emitting component.
