The described embodiments should not be regarded as limiting the present invention. All other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present invention.

[0080] In the following description, the terms "first\second\third" involved are merely used to distinguish similar objects and do not represent a specific ordering of the objects. It can be understood that "first\second\third" can be interchanged with a specific order or sequence where permitted, so that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.

[0081] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention belongs. The terms used herein are only for the purpose of describing the embodiments of the present invention and are not intended to limit the present invention.

[0082] The embodiments of the present invention provide a medical signal processing system and an analog output module, which can improve the mobility and portability of medical monitoring equipment. Figure 1 As shown, the medical signal processing system 1 provided in the embodiment of the present invention may include:

[0083] At least one sensor 11, a measuring module 12, an analog output module 13 and a target medical device 14; the analog output module 13 is arranged outside the measuring module 12; wherein,

[0084] At least one sensor 11, used to collect at least one vital sign signal from a human body;

[0085] The measuring module 12 is used to process at least one vital sign signal to obtain at least one digital signal; and send the at least one digital signal to the analog output module;

[0086] An analog output module 13, used to convert a target digital signal in at least one digital signal into an analog signal, and send the analog signal to a target medical device;

[0087] The target medical device 14 is used to implement a preset function based on the analog signal.

[0088] In the embodiment of the present invention, at least one sensor 11 is used to collect at least one vital sign signal from the human body, such as electrocardiogram, pulse, blood pressure, body temperature, blood oxygen, respiration, etc., and transmit the at least one vital sign signal to the measurement module 12. The measurement module 12 integrates the at least one vital sign signal, performs signal processing on different types of vital sign signals, such as the flow rate signal of human exhalation and inhalation collected by the gas sensor, the waveform signal representing the electrocardiogram collected by the electrode sensor, the blood pressure signal collected by the pressure sensor, etc., and generates a digital signal corresponding to each vital sign signal, thereby obtaining at least one digital signal.

[0089] In some implementations, at least one sensor 11 may be integrated inside the measuring module 12, or may be connected to the outside of the measuring module 12 through a circuit. In this way, by connecting at least one sensor 11 to the human body to collect at least one vital sign signal in real time and generating a corresponding digital signal through the measuring module 12, real-time human vital sign monitoring can be achieved.

[0090] In the embodiment of the present invention, the measuring module 12 sends at least one digital signal to the analog output module, and the analog output module 13 performs digital-to-analog conversion processing on the target digital signal in the at least one digital signal to convert the target digital signal into an analog signal. The analog output module 13 sends the analog signal to the target medical device 14.

[0091] In some embodiments, the target digital signal is a digital signal of a preset type. According to the needs of the target medical device 14, a digital signal of a corresponding type can be predetermined as the target digital signal. Among them, the target digital signal can include at least one signal type. In this way, in the analog output module 13, the preset type of digital signal recognition and digital-to-analog conversion are realized, and the digital-to-analog conversion can be performed on the target digital signal in at least one digital signal to obtain an analog signal corresponding to the target digital signal. It can be understood that in the case where the target digital signal includes a digital signal of at least one signal type, the analog signal also includes an analog signal corresponding to the digital signal of each signal type in at least one signal type. Furthermore, the target medical device 14 can sense the vital signs of the human body based on the analog signal output by the analog output module, and accordingly realize the treatment function.

[0092] Exemplarily, the target digital signal may include: at least one of an electrocardiogram (ECG) signal, a pulse signal, a blood pressure waveform, and a synchronization signal. For example, the ECG signal may include an electrocardiogram (ECG) waveform signal and / or a Pace mark of the ECG activity, and the blood pressure waveform signal may include an invasive blood pressure (IBP) signal, etc. The specific selection is made according to the actual situation, and the embodiment of the present invention is not limited. The target medical device 14 may include: at least one of a pacemaker, a defibrillator, and a balloon counterpulsator. Taking a pacemaker as an example, the pacemaker can monitor the abnormality of the human body's ECG activity according to the analog signal corresponding to the ECG signal output by the analog output module 13, thereby inhibiting or triggering the pacemaker to emit discharge pulses to achieve the pacing function.

[0093] It is understandable that the embodiment of the present invention sets the analog output module outside the measurement module, and the measurement module sends at least one digital signal obtained by processing at least one vital sign signal to the external analog output module, and the analog output module converts the target digital signal in the at least one digital signal into an analog signal and sends it to the target medical device, so that the target medical device can implement the preset function based on the analog signal. In this way, the circuit volume and circuit complexity of the measurement module are reduced, and the measurement module can be miniaturized to facilitate movement or human carrying, thereby improving the mobility and portability of the medical monitoring device.

[0094] In some embodiments, the analog output module 13 can be connected to the measuring module 12 by wired or wireless means. For wired connection, the analog output module 13 can be connected to the measuring module 12 by a serial bus or a power cable. For wired connection, the analog output module 13 can be connected to the measuring module 12 by short-distance communication or photoelectric connection.

[0095] In some embodiments, for serial bus connection, the measuring module 12 can output at least one digital signal to its own digital signal output interface, and the digital signal output interface of the measuring module 12 is connected to the digital signal input interface of the analog output module 13 through the serial bus, so as to realize that at least one digital signal is input into the analog output module through the serial bus. Exemplarily, the communication type of the digital interface may include but is not limited to at least one of an integrated circuit bus (Inter-Integrated Circuit, IIC), a serial peripheral interface (Serial Peripheral Interface, SPI), and a universal asynchronous receiver / transmitter (UART). Among them, for the serial bus connection mode of the UART interface, in order to reduce environmental interference, serial port level transmission such as RS232, RS485, or RS422 can be adopted.

[0096] In some embodiments, Figure 2 As shown, for the power cable connection, the carrier communication receiving circuit 130 can be integrated in the analog output module 13. The power input terminal of the analog output module 13 is connected to the measuring module 12 through the power cable, and the measuring module 12 provides the working power of the analog output module 13. In other words, the measuring module 12 can power the analog output module 13 through the power cable. In this way, while supplying power, the measuring module 12 can transmit at least one digital signal in the form of a carrier to the carrier communication receiving circuit 130 in the analog output module 13 through the power cable, and the carrier communication receiving circuit 130 receives and analyzes the signal in the form of a carrier, so that the analog output module obtains at least one digital signal.

[0097] In some embodiments, for a short-distance communication connection, a digital communication connection can be established between the analog output module 13 and the measurement module 12 via Bluetooth, wireless network (Wireless Fidelity, Wi-Fi), near field communication (Near Field Communication, NFC), etc.

[0098] In some embodiments, for optoelectronic connection, the analog output module 13 and the measurement module 12 may be connected via optoelectronic communication methods such as infrared and near infrared.

[0099] It should be noted that the analog output module 13 and the measuring module 12 may also be connected via other wired or wireless digital communication methods, such as mobile communication connection, etc. The specific selection is made according to actual conditions and is not limited in the embodiments of the present invention.

[0100] In some embodiments, the analog output module 13 can be arranged on a cable and connected to the target medical device 14 through the cable. Exemplarily, the analog output module 13 is arranged on the cable between the measuring module 12 and the target medical device 14, the input end of the analog output module 13 is connected to the output end of the measuring module 12 through the cable, and the output end of the analog output module 13 is connected to the input end of the target medical device 14 through the cable. For example, the input end of the analog output module 13 and the output end of the measuring module 12 can be connected in a serial communication interface manner, and the output end of the analog output module 13 and the input end of the target medical device 14 can be connected in an analog signal interface manner. In this way, at least one digital signal output by the measuring module 12 is transmitted to the analog output module 13 through the cable, and the analog output module 13 converts the target digital signal therein into an analog signal, and then transmits the analog signal to the target medical device 14 through the cable, so that the target medical device 14 can realize the preset function under the excitation of the analog signal. Since the analog output module 13 is arranged on the cable outside the measuring module 12 and does not occupy the volume of the measuring module 12, the measuring module 12 placed in front of the human body can be miniaturized, thereby improving the mobility and portability of the medical monitoring device.

[0101] For example, Figure 3 The analog output module 13-1 is shown on the cable 15. One end of the cable 15 can be connected to the measurement module 12, and the other end can be connected to the target medical device 14.

[0102] In some embodiments, the analog output module 13 can also be implemented as an external module, connected to the target medical device 14 through the external device interface of the target medical device 14, and connected to the measurement module 12 in a wireless manner. Exemplarily, the analog output module 13 can be implemented as a pluggable module, plugged into the external analog signal input interface of the target medical device 14, and wirelessly connected to the measurement module 12. Alternatively, the analog output module 13 can also be set inside the target medical device 14, connected through an internal circuit, etc., and the specific selection is made according to the actual situation, and the embodiment of the present invention is not limited.

[0103] In some embodiments, based on Figure 1 ,like Figure 4 As shown, the analog output module 13 includes: a digital-to-analog conversion circuit 131 and a waveform conversion circuit 132. The digital-to-analog conversion circuit 131 is used to convert the target digital signal into an initial analog signal; the waveform conversion circuit 132 is used to correct the initial analog signal to obtain an analog signal.

[0104] Exemplarily, the waveform conversion circuit 132 may include a driving circuit or a filtering circuit. The waveform conversion circuit 132 may correct the initial analog signal directly converted by the digital-to-analog conversion circuit so that the driving current or voltage amplitude of the analog signal output by the analog output module 13 can meet the expected requirements of the target medical device 14 and meet the needs of the target medical device 14 to work normally.

[0105] In some embodiments, since the analog output module 13 performs digital-to-analog conversion on a target digital signal in at least one digital signal, in order to enable the analog output module to identify the target digital signal from at least one digital signal, the measuring module 12 is further configured to send a preset identifier corresponding to the target digital signal to the analog output module 13. In this way, the analog output module can determine the target digital signal from at least one digital signal according to the preset identifier.

[0106] Exemplarily, when the measurement module 12 sends at least one digital signal to the analog output module 13 in a digital communication mode, the preset identifier can be written into the header field of the data packet corresponding to the target digital signal. In this way, the analog output module 13 can determine whether the digital signal is the target digital signal by parsing the header field of the data packet of each received digital signal. Alternatively, the measurement module 12 can also carry the preset identifier in the target digital signal in other ways to send the target digital signal and its corresponding preset identifier to the analog output module 13. The specific selection is made according to the actual situation, and the embodiment of the present invention is not limited.

[0107] In some embodiments, the target digital signal includes: a digital signal of at least one signal type. Accordingly, the analog output module 13 converts the target digital signal, and the obtained analog signal includes: an analog signal corresponding to the digital signal of each signal type in at least one signal type. In some possible embodiments, the above-mentioned preset identifier may be a unified identifier corresponding to at least one signal type. The analog output module 13 may determine the digital signal containing the preset identifier in at least one digital signal as the target digital signal, and then further parse the target digital signal, determine the signal type corresponding to each digital signal in the target digital signal, and perform digital-to-analog conversion on different signal types using corresponding digital-to-analog conversion methods to obtain analog signals corresponding to the digital signals of each signal type.

[0108] In some other possible embodiments, the preset identifier includes: at least one type identifier corresponding to at least one signal type. That is, the type identifiers corresponding to digital signals of different signal types in the target digital signal are also different. The analog output module 13 can determine the signal type corresponding to each digital signal according to the type identifier corresponding to each digital signal in the target digital signal; and perform digital-to-analog conversion on each digital signal according to the signal type corresponding to each digital signal to obtain an analog signal corresponding to each digital signal.

[0109] In some embodiments, the analog output module 13 includes: a first processor. Exemplarily, the first processor can be implemented by a microcontroller unit (MCU). Among them, the first processor can be used to receive, parse and process at least one digital signal sent by the measurement module 12. Exemplarily, the analog output module 13 can receive multiple waveform signals sent by the measurement module 12 through a serial port, and the first processor classifies the multiple waveform signals, and after classification, each type of waveform signal is subjected to digital-to-analog conversion to obtain a corresponding analog signal. Here, the digital-to-analog conversion can be implemented by a digital-to-analog conversion circuit inside the first processor, or by a digital-to-analog conversion circuit connected to the outside of the first processor. Exemplarily, the above-mentioned digital-to-analog conversion circuit 132 can be a digital-to-analog conversion circuit inside the MCU, or the MCU can send a digital signal to the analog output module 13, and the digital-to-analog conversion circuit connected to the first processor can realize the digital-to-analog conversion by the digital-to-analog conversion circuit.

[0110] In some embodiments, the analog output module 13 includes: a first processor 131 and at least one conversion circuit 132. The first processor 131 is used to send each digital signal to the corresponding conversion circuit according to the signal type corresponding to each digital signal in the target digital signal; at least one conversion circuit 132 is used to perform digital-to-analog conversion on the digital signal of the corresponding signal type to obtain an analog signal corresponding to each digital signal, thereby completing the digital-to-analog conversion of the target digital signal.

[0111] For example, Figure 5As shown, the measuring module 12 receives at least one vital sign signal transmitted by at least one sensor through the front-end sampling circuit 121, processes it into at least one digital signal through the second processor 122, and then sends the at least one digital signal to the analog output module 13 through the digital interface. The analog output module 13 receives at least one digital signal through the digital interface, determines the target digital signal from the at least one digital signal through the first processor, and sends each digital signal to the corresponding conversion circuit in at least one conversion circuit 132 according to the signal type corresponding to each digital signal in the target digital signal, and converts each digital signal into a corresponding analog signal through the conversion circuit corresponding to each digital signal in the target digital signal, and sends it to the target medical device 14 through the analog signal output interface.

[0112] It should be noted that, in some embodiments, one or more conversion circuits in at least one conversion circuit 132 may include the above-mentioned digital-to-analog conversion circuit and waveform conversion circuit. That is, the conversion circuit may include a digital-to-analog conversion circuit; it may also include a digital-to-analog conversion circuit and a waveform conversion circuit, and the circuit modules included in different conversion circuits in at least one conversion circuit may be the same or different, and the specific selection is made according to the actual situation, and the embodiment of the present invention does not limit it.

[0113] It is understandable that in the embodiment of the present invention, the analog output module can perform digital-to-analog conversion processing on at least one digital signal through the first processor, thereby improving the flexibility of signal processing. In addition, the external analog output module is responsible for various types of digital-to-analog conversion, which reduces the volume of the host such as the measurement module and improves the mobility and portability of the medical monitoring device.
