The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0028] When a person is in a state of death due to some reason such as cardiac arrest and respiratory arrest, resulting in loss of heart and lung function, people use some first aid methods to restore their heartbeat and breathing, and promote the blood to flow through various organs with oxygen to save the patient's life. This biological phenomenon of restoring lost heart and lung function is cardiopulmonary resuscitation. In the past, cardiopulmonary resuscitation was usually achieved by people using manual compression. With the improvement of medical standards, cardiopulmonary resuscitation technology has been continuously practiced, supplemented, and modified to improve it. Combined with the current level of science and technology, cardiopulmonary resuscitation can also be completed for patients with the help of cardiopulmonary resuscitation machines to improve the standardization and effectiveness of cardiopulmonary resuscitation. Usually, when using a cardiopulmonary resuscitation machine for cardiopulmonary resuscitation, corresponding cardiopulmonary resuscitation sensor equipment will also be configured to monitor the process of cardiopulmonary resuscitation and facilitate medical staff to understand the progress of cardiopulmonary resuscitation.

[0029] The cardiopulmonary resuscitation sensor device provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown, the cardiopulmonary resuscitation sensor device 104 is connected to the cardiopulmonary resuscitation machine 102, as an auxiliary device in the cardiopulmonary resuscitation process, to collect and display / prompt the cardiopulmonary resuscitation process. The cardiopulmonary resuscitation sensor device 104 is also connected to the host computer 106, which is convenient for remote monitoring of the cardiopulmonary resuscitation process. Among them, the monitored cardiopulmonary resuscitation process includes but is not limited to the output parameters of the cardiopulmonary resuscitation machine 102, such as compression depth, compression frequency and compression duration. The specifications and models of the cardiopulmonary resuscitation machine 102 are not limited, and it is sufficient to perform cardiopulmonary resuscitation on the patient. Similarly, the specifications and models of the host computer 106 are also not limited, and it is sufficient to exchange data with the cardiopulmonary resuscitation sensor device 104. Further, the cardiopulmonary resuscitation sensor device 104 can also be connected to medical auxiliary equipment, such as a defibrillator monitor, to complete the integrated emergency functions of cardiopulmonary resuscitation, defibrillation, and physiological parameter monitoring through data interaction between devices, and further ensure the treatment effect.

[0030] In one embodiment, Figure 2 As shown, a cardiopulmonary resuscitation sensing device 104 is provided, including a processor 202, a sensing unit 204, a power isolation unit 206, a wireless transmission unit 208 and a prompt unit 210, the processor 202 is connected to the sensing unit 204, the power isolation unit 206, the wireless transmission unit 208 and the prompt unit 210, and the power isolation unit 206 is connected to the wireless transmission unit 208 and the prompt unit 210.

[0031] Specifically, the sensing unit 204 can collect data from the connected cardiopulmonary resuscitation machine 102, that is, the sensing unit 204 collects cardiopulmonary resuscitation data, and the cardiopulmonary resuscitation data can be the output parameters of the cardiopulmonary resuscitation machine 102, such as compression depth, compression frequency, and compression duration. The sensing unit 204 transmits the collected cardiopulmonary resuscitation data to the processor 202, and the processor 202 can perform format conversion or data processing on the cardiopulmonary resuscitation data, and generate prompt instructions corresponding to the cardiopulmonary resuscitation data. The processor 202 sends the prompt instruction to the wireless transmission unit 208 and the prompt unit 210. After receiving the prompt instruction, the wireless transmission unit 208 generates a wireless signal for sending the cardiopulmonary resuscitation data in a wireless transmission manner. After receiving the prompt instruction, the prompt unit 210 generates a prompt signal for local prompting of the cardiopulmonary resuscitation data. The power supply isolation unit 206 is connected to the power input terminal, can obtain power, and isolate the power supply to the wireless transmission unit 208 and the prompt unit 210. At the same time, the power supply isolation unit 206 also supplies power to other power-requiring structures within the cardiopulmonary resuscitation sensor device 104, which are not listed here.

[0032] Furthermore, the wireless transmission unit 208 is a Bluetooth unit, and the prompt unit 210 is a voice unit. Driven by the prompt instruction of the processor 202, the Bluetooth unit can send the cardiopulmonary resuscitation data to the host computer 106 connected to the Bluetooth unit via Bluetooth. Since the power supply isolation unit 206 isolates and supplies power to the Bluetooth unit and the voice unit, power supply interference between the Bluetooth unit and the voice unit is avoided, so that the Bluetooth unit and the voice unit can work independently. Therefore, the voice unit is prevented from being interfered by the Bluetooth unit, and the problem of the voice unit being affected by the Bluetooth unit and having a "squeaky" digital sound is solved.

[0033] The voice unit may include a voice prompt unit 210 and a voice drive unit. The voice prompt unit 210 can prompt the medical staff with the cardiopulmonary resuscitation data in the form of voice broadcast under the drive of the prompt instruction of the processor 202. The voice drive unit can receive the voice instruction of the medical staff to complete the function setting, such as the power on and off behavior. Furthermore, the voice prompt unit 210 may include a speaker for increasing the prompt volume.

[0034] In this embodiment, the cardiopulmonary resuscitation sensor device 104 includes a processor 202, a sensing unit 204, a power isolation unit 206, a wireless transmission unit 208 and a prompt unit 210. The processor 202 is connected to the sensing unit 204, the power isolation unit 206, the wireless transmission unit 208 and the prompt unit 210, and the power isolation unit 206 is connected to the wireless transmission unit 208 and the prompt unit 210. The sensing unit 204 collects cardiopulmonary resuscitation data and transmits it to the processor 202. The processor 202 sends a prompt instruction to the wireless transmission unit 208 and the prompt unit 210. The wireless transmission unit 208 generates a wireless signal, and the prompt unit 210 generates a prompt signal; the power isolation unit 206 isolates and supplies power to the wireless transmission unit 208 and the prompt unit 210. By isolating and powering the wireless transmission unit 208 and the prompt unit 210, the interference between the units is reduced, so that the cardiopulmonary resuscitation sensor device 104 provided in the present application can be prompted in a diversified manner, thereby improving convenience.

[0035] In one embodiment, Figure 3 As shown, the power supply isolation unit 206 includes a first adapter unit 302 and a second adapter unit 304, wherein the first adapter unit 302 is connected to the wireless transmission unit 208, and the second adapter unit 304 is connected to the prompt unit 210. Specifically, the power supply isolation unit 206 supplies power to the wireless transmission unit 208 and the prompt unit 210, respectively, wherein the first adapter unit 302 is connected to the wireless transmission unit 208 and supplies power to the wireless transmission unit 208. The second adapter power supply is connected to the prompt unit 210 and supplies power to the prompt unit 210. Furthermore, the type or quantity of the prompt unit 210 is different, and the corresponding second adapter unit 304 is also different. In one embodiment, as Figure 3 As shown, the second adapter unit 304 includes a first adapter and a second adapter, both of which are connected to the prompt unit 210, and the working voltages of the first adapter and the second adapter are different. The prompt unit 210 may require different working voltages to work, and the second adapter unit 304 also needs to provide different working voltages to the prompt unit 210. The first adapter and the second adapter are both connected to the prompt unit 210, and are used to supply different working voltages to the prompt unit 210 to meet the working requirements of the prompt unit 210.

[0036] Further, the first adapter and the second adapter are adapters of different specifications or types. The adapter can realize voltage conversion. For example, the first adapter is an adapter that adjusts the working voltage to 3.3V, and the second adapter is an adapter that adjusts the working voltage to 5V. At the same time, the first adapter unit 302 may include an adapter of the same specification or type as the first adapter or the second adapter. For example, the first adapter unit 302 includes a third adapter, and the working voltage of the third adapter is the same as that of the first adapter, that is, the third adapter is an adapter that adjusts the working voltage to 3.3V.

[0037] The power supply isolation unit 206 may be connected to multiple power input terminals or one power input terminal. Figure 3 As shown, the cardiopulmonary resuscitation sensor device 104 also includes a power supply unit 306, and the power supply unit 306 is connected to the power supply isolation unit 206. That is, the power supply isolation unit 206 is connected to one power input terminal, which is connected to the power supply unit 306. The power supply unit 306 provides power to the power supply isolation unit 206, and then the power supply isolation unit 206 provides isolated power supply to the wireless transmission unit 208 and the prompt unit 210.

[0038] For example, Figure 4 As shown, the power supply unit 306 is a power supply, the first adapter unit 302 includes a lithium battery to 3.3V adapter, and the second adapter unit 304 includes a first adapter and a second adapter, the first adapter is a lithium battery to 3.3V adapter, and the second adapter is a lithium battery to 5V adapter. The first adapter unit 302 is isolated from the second adapter unit 304, and supplies power to the Bluetooth unit and the voice unit respectively. It can reduce electrical interference, ensure the smooth operation of the Bluetooth unit and the voice unit, and enable the cardiopulmonary resuscitation sensor device 104 to have a diversified cardiopulmonary resuscitation data prompt mode, which is convenient for medical staff to view and increases the convenience of the cardiopulmonary resuscitation sensor device 104.

[0039] In one embodiment, the sensing unit 204 includes a press determination unit and a press detection unit, and both the press determination unit and the press detection unit are connected to the processor 202 .

[0040] The pressing judgment unit is used to judge whether cardiopulmonary resuscitation has started, which can be judged by detecting the startup state of the cardiopulmonary resuscitation machine 102, or by detecting whether pressing has started. The pressing detection unit is used to detect cardiopulmonary resuscitation data after cardiopulmonary resuscitation starts, including but not limited to the pressing depth and pressing frequency. The cardiopulmonary resuscitation data obtained by the pressing detection unit and the pressing judgment unit are transmitted to the processor 202 for subsequent processing.

[0041] In one embodiment, the pressing judgment unit is a pressure sensor, and the pressing detection unit is a displacement sensor. The pressure sensor can detect whether the cardiopulmonary resuscitation machine 102 starts pressing. When the cardiopulmonary resuscitation machine 102 is working (pressing), the displacement sensor detects the pressing depth and pressing frequency. Furthermore, the pressure sensor is a flexible film pressure sensor, which can convert the pressure applied to the sensor film area into a change in resistance value, and finally convert it into a voltage signal that can be collected by the processor 202 to determine the start of pressing. The displacement sensor uses a 3-axis MEMS (Micro Electromechanical System) accelerometer, calculates the displacement by double integration of acceleration over time, calculates the pressing frequency by calculating the waveform cycle time of the acceleration, and converts the measured analog quantity into an outputtable digital quantity through a 16-bit ADC, and finally transmits the data to the processor 202 for processing through the serial port.

[0042] In one embodiment, the cardiopulmonary resuscitation sensor device 104 further includes a local display unit, which is connected to the processor 202 and the power supply isolation unit 206 .

[0043] Specifically, the local display unit can receive the prompt instruction sent by the processor 202, and display the corresponding cardiopulmonary resuscitation data according to the prompt instruction, providing more diversified data display for medical staff. Among them, the power supply of the local display unit is also provided by the power supply isolation unit 206, which has been similarly recorded above and will not be repeated here.

[0044] In order to enrich the prompting mode of the cardiopulmonary resuscitation sensor device 104, an LED display unit and a digital tube display unit can be set for display. In one embodiment, the local display unit includes an LED display unit and a digital tube display unit, and the LED display unit and the digital tube display unit are both connected to the processor 202 and the power supply isolation unit 206. Among them, the LED display unit includes a plurality of LED lights, and the LED lights can emit different colors to represent different cardiopulmonary resuscitation data, such as 8 LED tricolor lights. Different cardiopulmonary resuscitation data can also be represented by the number of LED lights that are lit. The digital tube display unit can directly display numerical values ​​through the digital tube, including but not limited to compression depth and compression frequency.

[0045] In one embodiment, the power supply unit 306 includes a charging unit and an energy storage unit, and the energy storage unit is connected to the charging unit and the power supply isolation unit 206. The energy storage unit is used to store electrical energy and is connected to the power supply isolation unit 206 to provide electrical energy to each unit, and the charging unit is used to supplement the electrical energy of the energy storage unit. Furthermore, the energy storage unit may be a lithium battery, such as a lithium battery with an output voltage of 3.8V and a capacity of 700mAh. The charging unit may include a charging adapter and a voltage regulating unit, and the voltage regulating unit is connected to the charging adapter and the energy storage unit, and is used to adjust the output voltage to cooperate with the energy storage unit for charging. The charging adapter is used to connect to an external power source, such as a power grid, a generator, etc.

[0046] Based on the same technical concept, Figure 1 As shown, an embodiment of the present application also provides a cardiopulmonary resuscitation system, including a cardiopulmonary resuscitation machine 102, a host computer 106 and a cardiopulmonary resuscitation sensor device 104 as described in the above embodiments, and the cardiopulmonary resuscitation sensor device 104 is connected to the cardiopulmonary resuscitation machine 102 and the host computer 106.

[0047] The host computer 106 may be a mobile phone, which may store APP software related to medical rescue. When the mobile phone receives the cardiopulmonary resuscitation data sent by the wireless transmission unit 208, the mobile phone may link the cardiopulmonary resuscitation data with the APP software to complete a more complex rescue process.

[0048] In order to better understand the above scheme, combined with Figure 1 The application scenario shown is explained in detail below in conjunction with a specific embodiment.

[0049] In one embodiment, a cardiopulmonary resuscitation sensing device is provided. The cardiopulmonary resuscitation sensing device can be used as an auxiliary device for cardiopulmonary resuscitation, and is used to assist manual / machine compression by displaying and storing data on compression depth and compression frequency in real time.

[0050] Physical picture of cardiopulmonary resuscitation sensor equipment Figure 5 As shown, the front shell 2 and the rear shell 9 form a shell, and a waterproof ring 8 is provided at the joint. The MCU (processor), the power supply isolation unit and the voice unit are welded on the PCB board 7, the Bluetooth unit 6 is arranged at the side edge of the pressing support block 5, the sensing unit 4 is arranged between the pressing support block 5 and the front shell 2, and the front shell soft glue TPU (thermoplastic polyurethane elastomer, also known as thermoplastic polyurethane rubber) 3 is attached to the corresponding position of the sensing unit 4 on the outside of the front shell 2. A glass screen 1 is provided on the front shell 2 next to the front shell soft glue TPU 3, and a display unit 11 is provided inside the front shell 2 at the corresponding position. The battery 12 is arranged on the battery support block 10, and each unit is powered by the power supply isolation unit.

[0051] CPR sensor equipment such as Figure 6As shown, it can be divided into a power supply module (power supply isolation unit), a charging module (voltage regulating unit in the power supply unit), a voice module (voice unit), a power on / off module, a storage module, a displacement sensor module, a pressure sensor module, a digital tube display module, an LED display module, a Bluetooth module (Bluetooth unit), a cable transmission module, and an MCU minimum system (processor).

[0052] Among them, the power supply module includes multiple adapters, only two of which are shown in the figure. It is used to boost or reduce the power supply of the lithium battery and then power the other parts of the cardiopulmonary resuscitation sensor device. The charging module can charge the lithium battery and can be connected to a charging adapter for voltage stabilization charging of the lithium battery. The charging adapter can also be directly connected to the power supply module to output the power in the connected cable (adapter cable and / or linkage cable). The voice module is connected to the MCU minimum system, including a voice amplifier module and a voice driver module. The voice amplifier module is controlled by the MCU minimum system and can convert electrical signals into sound signals, and then amplify the sound signals through the speaker to perform voice prompts and voice alarms. The voice driver module can receive voice commands and convert sound signals into electrical signals. The switch module is a switch. Medical staff can control the opening and closing of the entire cardiopulmonary resuscitation sensor device by triggering the switch module so that the MCU minimum system perceives the corresponding trigger action. The storage module can store cardiopulmonary resuscitation data, including but not limited to the signals generated by the pressure sensor module and the displacement sensor module. The displacement sensor module uses a 3-axis MEMS accelerometer. The displacement is calculated by double integration of acceleration over time. The compression frequency can be calculated by calculating the waveform cycle time of the acceleration. The measured analog quantity is converted into an output digital quantity through a 16-bit ADC, and finally the data is transmitted to the MCU minimum system through the serial port for processing. The pressure sensor uses a flexible film pressure sensor, which converts the pressure applied to the sensor film area into a change in resistance value, and finally converts it into a voltage signal that can be collected by the MCU minimum system to determine the start of compression. The digital tube display module is driven by the MCU minimum system through the digital tube driver module to display the compression frequency. The LED display module is driven by the MCU minimum system through the LED driver module to display the compression depth. The Bluetooth module can transmit cardiopulmonary resuscitation data to the host computer, such as a mobile phone APP. The cable transmission module is used to power the system and realize data interaction between modules, which facilitates the communication or control between the MCU minimum system and each module and peripherals. In order to make the cardiopulmonary resuscitation data accurate, the MCU minimum system is also connected to an RTC (clock chip) module to improve the clock accuracy.

[0053] The digital tube can display a pressing frequency range of 80cpm-160cpm, with an accuracy of 5%, a resolution of 1cpm, and a pressing frequency refresh rate greater than or equal to 0.5Hz. The pressing depth refresh rate of the LED is greater than or equal to 0.5Hz. The LED display module includes 8 three-color lamp beads for indicating the pressing depth, 1 three-color lamp bead for indicating the pressing frequency, and 1 three-color lamp bead for displaying the power. Each lamp bead can display red, yellow, and green.

[0054] When the pressing depth is 0cm, all 8 indicator lights indicating the pressing depth are off. When the pressing depth is 1cm-4cm, the pressing is too shallow, and 1-4 yellow LED lights are always on according to the pressing depth. When the pressing depth is 5cm-6cm, the pressing is normal, and 5-6 green LED lights are always on according to the pressing depth. When the pressing depth is greater than 6cm (including a detection error of 1cm), when the detected pressing depth is 7cm, 7 red LED lights are always on; when the detected pressing depth is 8cm or greater, 8 red LED lights are always on.

[0055] When the pressing frequency is too slow (less than 100cpm), the lamp bead indicating the pressing frequency flashes yellow; when the pressing frequency is normal (100cpm-120cpm), the lamp bead indicating the pressing frequency flashes green; when the pressing frequency is too fast (greater than 120cpm), the lamp bead indicating the pressing frequency flashes red. The flashing frequency is 110cpm.

[0056] When the battery is low, the indicator light will light up red; when the battery is charging, the indicator light will flash green; when the battery is low, the indicator light will light up green.

[0057] The Bluetooth module and the voice module both have the problem of digital noise "squeaking" because the voltage is usually not isolated when the Bluetooth module and the voice module are powered. The transmission signal of the Bluetooth module is crosstalked to the power amplifier end through the power supply, causing noise. The present application provides a power supply module composed of more than two adapters to isolate the power supply of the voice module and the Bluetooth module to reduce interference.

[0058] In this embodiment, not only can data be displayed at the same time, but also voice prompts and alarms can be given, and the emergency process data can be stored and transmitted by wire or wirelessly, and it can also be linked with the defibrillator monitor to perform necessary electric defibrillation and physiological parameter monitoring functions while performing effective cardiopulmonary resuscitation, thereby improving the efficiency of rescue. At the same time, by eliminating interference between modules, the cardiopulmonary resuscitation sensor device provided by this application can provide prompts in a diversified manner, thereby improving convenience.

[0059] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0060] The above-mentioned embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the attached claims.
