The physiological data acquisition device comprises an acquisition box, lead wires and a measurement end. The lead wires are connected between the acquisition box and the measurement end. Each lead wire comprises one or more first lead wires with impedance greater than a preset threshold. The measurement end is used to adhere to a patient's body to obtain a measurement signal. The first lead wire is used to step down the measurement signal. The acquisition box is used to process the measurement signal after step-down to obtain physiological measurement data. Thus, the application uses the impedance of the first lead wire as a defibrillation protection component. In the process of entering the acquisition box from the human body through the first lead wire under high-voltage defibrillation, the first lead wire itself has appropriate impedance, which can realize step-down processing of high-voltage defibrillation, and an additional separate high-power resistor is not needed to realize high-voltage protection, so that the acquisition box is miniaturized.

Description

TECHNICAL FIELD

[0001] The present application relates to a physiological data monitoring device, in particular to a monitoring system and a physiological data acquisition device thereof. BACKGROUND

[0002] ECG (Electrocardiograph) measurement system is used to record the electrical activity of the heart over a period of time by measuring the potential of the living tissue surface. The current ECG measurement system adopts multiple leads, for example, 6 leads or 12 leads. One end of the multiple lead wires is used to contact the testee, and the multiple lead wires are connected to an ECG processing module. The ECG signal is input into the ECG processing module for processing, so as to realize the measurement of the ECG signal.

[0003] When the patient needs defibrillation treatment (or electro knife), if the lead wire still needs to be connected to the patient to monitor the heartbeat information of the patient in real time, the high voltage and current conducted by the lead wire during defibrillation or electro knife treatment may cause damage to the ECG measurement system or have an impact on the measurement data. Therefore, the ECG measurement system needs to be designed with a defibrillation protection circuit / anti-defibrillation circuit to realize voltage reduction or voltage clamping, so as to avoid the above problems. Taking the defibrillation protection circuit as an example, it needs to ensure that the absorption of the defibrillation energy by the ECG processing module is less than the standard requirement, and protect the ECG processing module from being damaged by the defibrillation energy.

[0004] Therefore, how to design an ECG measurement system / device with a defibrillation protection function to meet the above requirements, and in particular, for a wearable ECG measurement device, how to avoid the impact on the ECG measurement system during defibrillation treatment while maintaining the miniaturization of the device, has become a problem to be solved. SUMMARY

[0005] The embodiments of the present application disclose a monitoring system and a physiological data acquisition device thereof, which are suitable for a portable wearable physiological data measurement system to solve the above problems.

[0006] In a first aspect, the embodiments of the present application disclose a physiological data acquisition device, comprising: an acquisition box, lead wires and a measurement end; the lead wires are connected between the acquisition box and the measurement end; each of the lead wires comprises one or more first lead wires with an impedance greater than a preset threshold; the measurement end is used to adhere to the patient's body to obtain a measurement signal; the first lead wires are used to reduce the voltage of the measurement signal; and the acquisition box is used to process the measurement signal after voltage reduction to obtain physiological measurement data.

[0007] Secondly, embodiments of this application disclose a monitoring system, including a monitoring device and a physiological data acquisition device as disclosed in the first aspect, wherein the monitoring device includes a main housing and a control module disposed within the main housing, and the monitoring device and the acquisition box are connected via wireless communication.

[0009] Therefore, this application uses the self-impedance of the first lead wire as the defibrillation protection component. During the process of the defibrillation high voltage entering the acquisition box from the human body through the first lead wire, the first lead wire itself has appropriate impedance, which can realize the voltage reduction of the defibrillation high voltage. There is no need for additional discrete high-power resistor devices to achieve high voltage protection. The interface withstand voltage requirements are low, and the acquisition box is miniaturized. While providing better comfort, it ensures that its defibrillation protection performance meets the standard requirements. Attached Figure Description

[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0028] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish different objects, not to describe a specific order. Furthermore, the term "comprising," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or apparatuses.

[0029] The following description provides preferred embodiments for carrying out this application; however, this description is for the purpose of illustrating the general principles of this application and is not intended to limit the scope of this application. The scope of protection of this application shall be determined by the appended claims.

[0030] Please refer to Figure 1 , Figure 1 This is a schematic diagram of a physiological data acquisition device 30 according to an embodiment of this application. The physiological data acquisition device 30 is used to acquire physiological data of a monitored subject. The physiological data acquisition device 30 includes an acquisition box 31, lead wires 32, and a measurement terminal 33. The lead wires 32 connect the acquisition box 31 and the measurement terminal 33. Each lead wire 32 includes at least one or more first lead wires 322 with an impedance greater than a preset threshold. The measurement terminal 33 is used to conform to the patient's body to obtain a measurement signal. The first lead wires 322 are used to reduce the voltage of the measurement signal, and the acquisition box 31 is used to perform signal processing on the reduced-voltage measurement signal to obtain physiological measurement data.

[0031] Therefore, this application uses the self-impedance of the first lead 322 as a defibrillation protection component. During the process of the defibrillation high voltage entering the acquisition box 31 from the human body through the first lead 322, the first lead 322 itself has appropriate impedance, which can realize the voltage reduction of the defibrillation high voltage. There is no need for additional discrete high-power resistor devices to achieve high voltage protection, the interface withstand voltage requirement is low, and the acquisition box 31 is miniaturized. While providing better comfort, it ensures that its defibrillation protection performance meets the standard requirements.

[0032] This application selects the material of the core wire of the first lead 322 to meet the requirements of circuit defibrillation protection. The selection of materials primarily considers resistivity and power parameters; for example, a lead length of 0.3m and a cross-sectional area of ​​0.16mm² are used. 2 For example, to achieve a resistance of 40kΩ, the resistivity of the required material must be no less than 21.3mΩ*m, and the power it can withstand must be no less than 400W. Therefore, since the resistivity of commonly used metal wires is too low to meet the impedance requirements, the core wire of the first conductor 322 needs to be made of other materials. For example, conductive polymer composite materials, including carbon fiber composites and conductive PVC, can be used.

[0033] Specifically, in one embodiment, at least a portion of the core wires of the one or more first conductors 322 is made of a polymer conductive composite material.

[0034] Furthermore, in one embodiment, the polymer conductive composite material comprises a mixture of a conductive polymer matrix material and a conductive filler. The conductive polymer matrix material is used to firmly bond the conductive particles together, giving the conductive filler stable conductivity, and also imparting processability to the material. The conductive filler provides charge carriers, and its morphology, properties, and amount directly determine the conductivity of the material.

[0035] In one embodiment, the conductive filler is conductive particles, that is, the polymer conductive composite material is achieved by doping with conductive particles. When the filler concentration of conductive particles is low, the conductive particles are dispersed in the polymer with little contact with each other, resulting in very low conductivity. As the filler concentration increases, the filler particles have more opportunities to contact each other, and the conductivity gradually increases. When the filler concentration reaches a certain critical value, the filler particles in the system contact each other to form a wireless network. This network, like a metal mesh, runs through the polymer, forming conductive channels, thus the conductivity increases sharply, making the polymer a conductor.

[0036] Further, in one embodiment, the conductive polymer matrix material includes any one or more of the following: polyethylene, polypropylene, polyvinyl chloride, polystyrene, ABS, epoxy resin, acrylate resin, phenolic resin, unsaturated polyester, polyurethane, polyimide, silicone resin, butyl rubber, styrene-butadiene rubber, nitrile rubber, and natural rubber.

[0037] Further, in one embodiment, the conductive filler includes any one or more of the following: gold powder, silver powder, copper powder, nickel powder, palladium powder, molybdenum powder, aluminum powder, cobalt powder, silver-plated silica powder, silver-plated glass microspheres, carbon black, graphite, tungsten carbide, and nickel carbide.

[0038] Furthermore, in one embodiment, the polymer conductive composite material is a carbon fiber composite material or conductive polyvinyl chloride.

[0039] Alternatively, in one embodiment, each conductor 32 may consist only of the first conductor 322 or may be composed of one or more segments of the first conductor 322 and one or more segments of conductive wire spliced ​​together. Specifically, in the scheme where the core wire of each conductor 32 is replaced with a polymer conductive composite material cable, the core wire of the entire conductor 32 may be replaced with a polymer conductive composite material cable; that is, each conductor 32 may consist only of the first conductor 322. Alternatively, as... Figure 1As shown, the core wire portion of the entire conductive wire 32 can also be replaced with a polymer conductive composite material cable. For example, the core wire of the conductive wire 32 can be a hybrid structure of a conductive wire 320 and the first conductive wire 322 including the polymer conductive composite material cable. Further, in one embodiment, the conductive wire 320 and the polymer conductive composite material cable can be connected by crimping. That is, each conductive wire 32 is composed of one or more segments of the first conductive wire 322 and one or more segments of the conductive wire 320 spliced ​​together.

[0040] Thus, through this splicing, the self-impedance of one or more segments of the first lead wire 322 serves as a defibrillation protection component. During the process of the defibrillation high voltage entering the acquisition box 31 from the human body through one or more segments of the first lead wire 322, the high voltage of the defibrillation can be reduced due to the appropriate impedance of the one or more segments of the first lead wire 322. No additional discrete high-power resistor devices are needed for high voltage protection, making the monitoring system 100 structurally simple, with low interface withstand voltage requirements, and very convenient for the defibrillation protection design of miniaturized ECG measurement devices such as wearable devices or measurement devices that have direct electrical coupling with the monitored object.

[0041] The connecting wire 32 can be a single-core wire or a multi-core wire. When the connecting wire 32 is a single-core wire, this core wire can be completely replaced with the polymer conductive composite material cable, or partially replaced with the polymer conductive composite material cable.

[0042] Alternatively, in another embodiment, when the lead wire 32 is as follows: Figure 2 When the multi-core circular conductor 2 is shown, among which, Figure 2 In the multi-core circular conductor 2, 4 is a single core wire, 6 is an outer metal shielding layer, 7 is the conductor inside the single core wire 4, 5 is the insulation layer between the single core wire 4 and the conductor 7, 8 is a metal ground wire, and 9 is the multi-core wire insulation sheath. Typically, the insulation layer 5 and the multi-core wire insulation sheath 9 can be made of insulating materials with a withstand voltage greater than 5kV. In the multi-core circular conductor 2, at least one of the conductors 7 can be entirely replaced with the polymer conductive composite material cable, or partially replaced with the polymer conductive composite material cable.

[0043] Alternatively, in another embodiment, when the lead wire 32 is as follows: Figure 3 The flat structure of the lead wire 301 shown is as follows: Figure 3In the above, 350 is the outer sheath; 310 and 320 are conductors; 330 is the ground wire; and 340 is the inner sheath. In the flat structure conductor 301, at least one of the multiple conductors 310 and 320 can be completely replaced with the polymer conductive composite material cable, or partially replaced with the polymer conductive composite material cable.

[0044] Furthermore, in one embodiment, the first lead wire 322 is positioned at one or more of the following locations: one end of the lead wire 32 near the acquisition box 31, one end of the lead wire 32 near the measurement end 33, and any position in the middle of the lead wire 322.

[0045] Furthermore, in one embodiment, there are multiple leads 32, with one end of each lead 32 connected to the acquisition box 31 and the other end connected to a measurement terminal 33. The multiple leads 32 can be arranged as follows: Figure 4 The set of one-wire leads shown is 400, or it can also be formed as follows: Figure 5 The diagram shows a set of 500 branching leads. It is understandable that... Figure 4 In this configuration, the set of one-wire leads 400 includes five leads 32, each lead 32 connected to a measurement terminal 33a. The set of one-wire leads 500 extends from one end of the acquisition box 31 to one end of each of the five measurement terminals 33a. Each time it passes a measurement terminal 33a, the lead 32 connected to that terminal is disconnected, until the last measurement terminal 33a, where it connects to the last lead 32. Figure 5 In this configuration, the tree-branch type lead wire 500 includes five lead wires 32. One end of each lead wire 32 is connected to the acquisition box 31, and the other end is connected to the measurement end 33b. The ends of the five lead wires 32 closest to the acquisition box 31 are bound together to form the main trunk, while the ends of the five lead wires 32 furthest from the acquisition box 31 are separated to form branches.

[0046] Furthermore, in one embodiment, please refer again to Figure 1 The acquisition box 31 is provided with a first connector 34 for connecting the lead wire 32, and the first connector 34 is a pluggable structure. This allows the acquisition box 31 and the lead wire 32 to be detachably connected for convenient use. It is understood that in other embodiments, the first connector 34 may be omitted, and the acquisition box 31 is directly connected to the lead wire 32.

[0047] Furthermore, in one embodiment, please refer to Figure 6 , Figure 6 for Figure 1The circuit diagram of the physiological data acquisition device 30 is shown below. The acquisition box 31 is also equipped with a step-down circuit 310, which includes multiple clamping diodes D1. The negative terminal of each clamping diode D1 is connected to the first connector 34, and the positive terminals of all clamping diodes D1 are electrically connected to each other.

[0048] In some embodiments, the positive terminals of all clamping diodes D1 are electrically connected to each other and then connected to a ground point.

[0049] The plurality of clamping diodes D1 can be Zener diodes.

[0050] Therefore, when the voltage of the measurement signal that has been stepped down through the first lead 322 is higher than the trigger voltage, all clamping diodes D1 step down the voltage of the measurement signal to a preset voltage. The measurement signal that has been stepped down to the preset voltage can then be processed to obtain the physiological measurement data.

[0051] Furthermore, in one embodiment, please refer again to Figure 6 The acquisition box 31 also contains a signal processing module 313, and the plurality of clamping diodes D1 are electrically connected to the signal processing module 313. The measurement signal, which is stepped down via the first lead 322 and the corresponding clamping diode D1, is processed by the signal processing module 313 to obtain the physiological measurement data.

[0052] Furthermore, in one embodiment, please also refer to Figure 7 The acquisition box 31 also includes at least two circuit boards 312, which are stacked to form a layered structure. The signal processing module 313 is disposed on at least one of the circuit boards 312. Therefore, by using a layered structure, the space of the acquisition box 31 can be effectively utilized, reducing the dimensions of the acquisition box 31 in both length and width directions.

[0053] Wherein, when the acquisition box 31 includes at least two circuit boards 312, and the at least two circuit boards 312 are stacked, at least one side of each circuit board 312 is provided with the signal processing module 313 and the plurality of clamping diodes D1, and at least one circuit board 312 is provided with the signal processing module 313 and the plurality of clamping diodes D1 on both sides.

[0054] Among them, such as Figure 7 As shown, an insulating material J1 is disposed between two adjacent circuit boards 312. The insulating material J1 is used to electrically isolate each two adjacent circuit boards 312 in the at least two stacked circuit boards 312.

[0055] Wherein, the insulating material J1 can be an insulating material such as plastic or resin. Figure 7 As shown, the insulating material J1 can be formed into a layered / sheet-like structure, extending completely between two adjacent circuit boards 312. That is, the projection of the insulating material J1 on the circuit board 312 can coincide with the circuit board 312. Obviously, the insulating material J1 can also extend only to the area where the signal processing module 313 and the plurality of clamping diodes D1 are disposed.

[0056] like Figure 7 As shown, the acquisition box 31 also includes a housing 311, in which the aforementioned circuit boards 312 and the like are located. The insulating material J1 can be epoxy resin or the like, and the insulating material J1 can fill between every two circuit boards 312 and between the circuit boards 312 and the inner wall of the housing 311. In some embodiments, the housing 311 can be completely filled with the insulating material J1. This can be achieved by evacuating the internal space of the housing 311 and then using the negative pressure inside the housing 311 to draw out the epoxy resin in its adhesive state, thereby filling the housing 311 with epoxy resin. This achieves encapsulation and effective insulation of the circuit components included in the acquisition box 31, and also ensures the integrity and consistency of the filling, thus realizing the miniaturization of the acquisition box 31. Of course, in other embodiments, after the insulating material J1 encapsulates all the circuit components inside the acquisition box 31, including the circuit boards 312, the housing 311 can be directly formed from the insulating material J1.

[0057] When the signal processing module 313 and / or the plurality of clamping diodes D1 are provided on both sides of a circuit board 312, the signal processing module 313 and the plurality of clamping diodes D1 provided on both sides of the circuit board 312 can also be electrically connected through conductive holes penetrating both sides of the circuit board 312 if necessary.

[0058] For example, when different components of the signal processing module 313 are provided on both sides of a circuit board 312, the different components of the signal processing module 313 on both sides of the circuit board 312 can be electrically connected through conductive holes penetrating both sides of the circuit board 312.

[0059] Alternatively, in one embodiment, please refer to Figure 8 The acquisition box 31 includes at least two circuit boards 312', which are laid flat. The signal processing module 313 and the plurality of clamping diodes D1 are disposed on different circuit boards 312'.

[0060] That is, in other embodiments, the signal processing module 313 and the plurality of clamping diodes D1 are respectively disposed on different circuit boards 312'. Obviously, the plurality of different circuit boards 312' can be connected to form a large circuit board through flexible circuit boards, conductive lines, etc.

[0061] Alternatively, in one embodiment, when the first connector 34 is provided with a pluggable male or female connector, the acquisition box 31 further includes: a communication conversion circuit. This communication conversion circuit is disposed on any layer of at least two circuit boards 312, 312', or it can be disposed in two parts on at least two circuit boards 312, 312', or it can be disposed on an independent substrate and stacked on top of at least two circuit boards 312, 312'; or it can be disposed on an independent substrate and laid flat on at least two circuit boards 312, 312'. The lead wire 32 is electrically connected to the communication conversion circuit via the first connector 34, enabling signal transmission. The communication conversion circuit includes a female connector or a male connector. In this embodiment, the first lead wire 322 can be disposed at any position.

[0062] Furthermore, in one embodiment, please refer to Figure 9 The signal processing module 313 includes an analog signal processing circuit 3131 and a digital signal processing circuit 3133. The analog signal processing circuit 3131 includes at least a filtering and amplification circuit; the digital signal processing circuit 3133 includes at least an analog-to-digital converter circuit. Of course, in one embodiment, the analog-to-digital converter circuit and the filtering and amplification circuit can be implemented using integrated chips. The analog signal processing circuit 3131 is connected between the step-down circuit 310 and the digital signal processing circuit 3133. The analog signal processing circuit 3131 is used to perform analog-to-digital conversion on the measurement signal after it has been stepped down by the step-down circuit 310 to obtain a digital measurement signal. The digital signal processing circuit 3133 is used to further analyze and process the digital measurement signal, for example, by performing noise reduction processing, etc. The analog signal processing circuit 3131 and the digital signal processing circuit 3133 can be disposed on the same side of the same circuit board 312, or they can be disposed on two sides of the same circuit board 312 respectively. Alternatively, when the number of circuit boards 312 is at least two stacked circuit boards 312, the analog signal processing circuit 3131 and the digital signal processing circuit 3133 can be disposed in corresponding positions on different circuit boards 312 respectively.

[0063] like Figure 9As shown, in some embodiments, the data acquisition box 31 further includes a motion sensing circuit 315, which is connected to the signal processing module 313, specifically, to the digital signal processing circuit 3133. The motion sensing circuit 315 includes, but is not limited to, a gyroscope, an accelerometer, etc. Because the data acquisition box 31 is small and lightweight, it can be clipped to the collar, or its back can be attached to the patient's body or hospital gown, thus facilitating the monitoring of the patient's movement.

[0064] like Figure 9 As shown, in some embodiments, the acquisition box 31 further includes an alarm circuit 316, which is connected to the signal processing module 313, specifically to the digital signal processing circuit 3133. The signal processing module 313 can also be used to control the alarm circuit 316 to sound an alarm when an anomaly is detected, i.e., when an alarm limit is exceeded. For example, if the number of received measurement signals is less than a preset number, the signal processing module 313 determines that the measurement end 33 of the lead wire 32 has become detached and generates an alarm signal.

[0065] The alarm circuit 316 can be a vibrator, buzzer, alarm indicator light, loudspeaker, etc. The alarm indicator light is used to remind the patient of information through sound frequency. The loudspeaker is used to convey nurses' ward round notices, etc., through audio information.

[0066] like Figure 9 As shown, the acquisition box 31 may further include a voice circuit 317, which is used to input or output voice information. The voice circuit 317 is also connected to the signal processing module 313, specifically to the digital signal processing circuit 3133. The signal processing module 313 can also control the voice circuit 317 to output voice signals under specific conditions. For example, when the preset measurement time arrives, the voice circuit 317 can be controlled to issue a prompt voice to remind the user to lie down or sit still, thereby ensuring the accuracy of the measurement.

[0067] In some embodiments, when the signal processing module 313 detects an anomaly, it can also control the voice circuit 317 to output a voice alarm signal.

[0068] like Figure 9 As shown, the acquisition box 31 also includes a power supply 318, which is used to power the circuit components in the acquisition box 31, such as the signal processing module 313 and the wireless communication module 30. The power supply 318 can be a rechargeable battery such as a lithium battery and is connected to a DC power supply circuit to power the circuit components in the acquisition box 31.

[0069] The motion sensing circuit 315, the alarm circuit 316, the voice circuit 317, and the power supply 318 are all disposed on at least one of at least two circuit boards 312 and 312' of the circuit board 312, and / or disposed on an independent substrate, which is laid flat or stacked with at least two circuit boards 312 and 312'.

[0070] Alternatively, in one embodiment, the acquisition box 31 may further include a cable storage structure, such as a latch, to secure excess cables and prevent cable tangling.

[0071] Furthermore, in one embodiment, the measuring end 33 includes a skin contact sensor 35 connected in series with each lead wire 32, the skin contact sensor 35 being used to measure one or more of the patient's heart rate, pulse rate, respiratory rate, electroencephalogram, muscle relaxation, and body temperature.

[0072] Furthermore, in one embodiment, the skin electrical contact sensor 35 has at least two electrode pads or electrical conduction components capable of directly applying a weak current or voltage to the skin surface of the monitored object.

[0073] In one embodiment, each of the at least two electrode pads or electrical conduction components is fixed to a specific location on the monitored individual's body. The electrical conduction component can be a conductive component capable of direct contact with human skin, such as an electrical contact component for a muscle relaxation sensor or an electrical contact component for electroencephalography (EEG).

[0074] Alternatively, in one embodiment, when the skin electrical contact sensor 35 has an electrode pad or electrical conduction component, it can collect data such as heart rate.

[0075] Alternatively, in one embodiment, the skin electrical contact sensor 35 has two or more electrode pads or electrical conduction components, which can collect values ​​and waveforms such as heart rate, pulse rate, respiratory rate, electroencephalogram, and muscle relaxation.

[0076] Alternatively, in one embodiment, the skin electrical contact sensor 35 has three or more electrode pads or electrical conduction components, which can be used to collect more detailed analytical values ​​and more complete waveforms such as heart rate, pulse rate, respiratory rate, electroencephalogram, and muscle relaxation, for example, an electrocardiogram.

[0077] Alternatively, in one embodiment, the measuring end 33 includes a sensor connector 36 connected in series with each lead wire 32, the sensor connector 36 being used to hold a skin contact sensor 35, the skin contact sensor 35 being used to measure one or more of the patient's heart rate, pulse rate, respiratory rate, electroencephalogram, muscle relaxation, and body temperature.

[0078] Furthermore, in one embodiment, the electrode pads or conductive components in the skin electrical contact sensor 35 can be fixed to the lead wire 32 via sensor connectors. The number of sensor connectors 36 is the same as the number of electrode pads or conductive components. Each sensor connector 36 has two electrical connection ports, one of which is electrically connected to the electrode pad or conductive component, and the other is electrically connected to the lead wire 32. Each electrical connection port corresponding to one electrode pad or conductive component is connected to a wire, and all wires are arranged side-by-side or stacked to form a flat or circular lead wire.

[0079] Alternatively, in one embodiment, please refer to Figure 10 and Figure 11 The physiological data acquisition device 30 also includes a main cable 35 and a second connector 36. The first connector 34 connects the acquisition box 31 and one end of the main cable 35, while the second connector 36 connects one end of the main cable 35 and one end of the lead wire 32. In this case, the step-down circuit 310 is located in the second connector 36, and with the corresponding impedance of the lead wire 32, the system's defibrillation protection function can be achieved. Therefore, the pins of the first connector 34 do not require high withstand voltage, allowing for a miniaturized design. The entire system has a simple structure, requires fewer defibrillation protection devices, has no external modules, and is convenient and easy to use.

[0080] Please see Figure 12 , Figure 12 This is a schematic diagram of a monitoring system 100 according to an embodiment of this application. The monitoring system 100 includes the aforementioned physiological data acquisition device 30 and monitoring device 10.

[0083] In some embodiments, the monitoring device 10 includes at least one of a wearable monitor, a bedside monitor, a department-level workstation, and a hospital-level data center / hospital-level emergency center management device. When the monitoring system 100 is a wearable monitoring system, the monitoring device 10 is a wearable monitor.

This allows medical staff located at the department-level workstation and the hospital-level data center / hospital-level emergency center management device to view the information.

[0085] Please see Figure 13 This is a schematic diagram of a monitoring system 100 according to another embodiment of this application. The monitoring system 100 includes the aforementioned physiological data acquisition device 30 and monitoring device 10. The monitoring device includes a main housing and a control module disposed within the main housing. The monitoring device 10 is a wearable monitoring device or a bedside monitoring device. The wireless communication unit 319 included in the acquisition box 31 includes a near-field communication module 3191 and a far-field communication module 3192.

[0086] The monitoring device 10's wireless communication unit 101 includes at least a near-field communication module. Specifically, the acquisition box 31 can establish a wireless communication connection with the monitoring device 10 via the near-field communication module 3191 to send target measurement signals to the monitoring device 10.

This data is then available for viewing by medical personnel located at the department-level workstations and hospital-level data centers / hospital-level emergency center management devices.

[0087] Obviously, in other embodiments, the wireless communication unit 319 of the acquisition box 31 and the wireless communication unit 101 of the monitoring device 10 may both include a near-field communication module and a far-field communication module.

[0088] Please see Figure 14 This is a schematic diagram of a monitoring system 100 according to another embodiment of this application. The monitoring system 100 includes the aforementioned physiological data acquisition device 30 and monitoring device 10. The monitoring device includes a main housing and a control module disposed within the main housing. The monitoring device 10 is a wearable monitoring device that can be worn on a patient's wrist. The monitoring system 100 also includes a third connector 40 and a transmission cable 50. The monitoring device 10 is connected to one end of the transmission cable 50 via the third connector 40, and the other end of the transmission cable 50 is electrically connected to the acquisition box 30, allowing the monitoring device 10 to communicate with the acquisition box 30 via the transmission cable 50.

[0089] Therefore, during defibrillation treatment, after the high voltage from the lead wire 32 enters the acquisition box 31 via the step-down circuit 310, the voltage between the core wires in the transmission cable 50 is limited to no more than 20V, meaning the withstand voltage requirement between the core wires in the transmission cable 50 is relatively low. Thus, the insulation material between the core wires in the transmission cable 50 can be designed with a thinner material and lower withstand voltage requirements, resulting in a thinner transmission cable 50 to improve comfort during use.

[0090] Please refer to Figure 15In one embodiment, the data acquisition box 30 and the monitoring device 10 are detachably connected via the third connector 40. After passing through the data acquisition box 30, the withstand voltage requirement between the core wires in the transmission cable 50 is no greater than 20V. Since the pins 41 of the third connector 40 are connected to the core wires in the transmission cable 50, the withstand voltage requirement between the pins 41 of the third connector 40 is also no greater than 20V. Therefore, a smaller model of the third connector 40 can be selected to connect with the monitoring device 10. For the monitoring device 10, since it no longer includes a step-down circuit, its circuit board area is smaller, making it easier to achieve miniaturized module design, especially beneficial for miniaturizing the connector.

[0091] Please see Figure 16 This is a schematic diagram of the monitoring system 100 worn by the subject. In some embodiments, the monitoring device 10 included in the monitoring system 100 is a wearable monitoring device, such as a wristband monitoring device, a head-mounted monitoring device, etc. Figure 16 As shown, the monitoring device 10 is a wristband-type monitoring device worn on the wrist of the subject. The data collection box 31 is connected to the subject's skin via a lead wire 32, and the outer shell 311 of the data collection box 31 (as shown) Figure 7 The outer surface of the sample collection box 31 may be provided with an adhesive material, which can be adhered to the skin of the subject to achieve stable wearing.

[0092] In some embodiments, at least one suction cup may be provided on an outer surface of the housing 311 of the collection box 31, which can be used to adhere to the skin of the subject, thereby achieving stable wearing of the collection box 31. Since the collection box 31 and the monitoring device 10 are connected wirelessly, the inconvenience of wearing wireless connections is avoided, improving the user experience.

[0093] Therefore, the monitoring system 100 and its physiological data acquisition device 30 of this application place the defibrillator 3101 outside the acquisition box 31, so that the defibrillator 3101 is connected in series with the lead wire 32 and packaged together with the lead wire 32. This eliminates the need for the circuit board inside the acquisition box 31 for setting the defibrillator 3101, making the acquisition box 31 smaller while improving its pressure resistance. It also ensures that its defibrillation protection performance meets the standard requirements while providing better comfort. The target measurement signal is transmitted to the target monitoring device 10 wirelessly, avoiding the constraints of wires, meeting the ECG measurement requirements, and facilitating the user's movement.

[0094] Alternatively, in one embodiment, the monitoring device 10 further includes a display component, which can be used to search for patient historical information and display current information for easy access.

The description of the embodiments above is only for the purpose of helping to understand the method and core ideas of this application. At the same time, for those skilled in the art, there will be changes in specific embodiments and application scope based on the ideas of this application. Therefore, the content of this specification should not be construed as a limitation of this application.
