[0022] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention

[0023] The present invention provides a respiratory cry recording device for newborns

[0024] Please refer to Figures 1 to 4 , in an embodiment of the present invention, the respiratory cry recording device for newborns includes: Warning mechanism 1, the warning mechanism 1 includes a base 11 and a first magnetic member 13, a sound amplification port 12 is arranged on the periphery of the base 11, and the first magnetic member 13 is embedded and installed at the bottom of the base 11 Collection mechanism 2, the collection mechanism 2 includes a movable box 21, an infrared camera 22, a sound collector 23, a second magnetic member 24 and a power supply module 25, a switch port 211 is opened at the bottom of the movable box 21, the infrared camera 22 is installed on the top of the movable box 21, the sound collector 23 is arranged around the top of the movable box 21, the second magnetic member 24 is embedded and installed at the bottom of the movable box 21, the bottom of the movable box 21 is inserted into the top of the base 11, and the power supply module 25 is installed in the movable box 21 Locking connection mechanism 8, the locking connection mechanism 8 includes a locking pin 81, one end of the locking pin 81 is fixedly connected to the base 11, and the other end of the locking pin 81 is inserted into the switch port 211 and abuts against the movable box 21 Signal sending device 4, the signal sending device 4 is installed on the movable box 21 Signal transceiver device 5, the signal transceiver device 5 is installed on the base 11 Player 6, the player 6 is installed on the base 11, and the player 6 is aligned with the sound amplification port 12 When the movable box 21 is inserted into the base 11, the first magnetic member 13 and the second magnetic member 24 repel each other; when the movable box 21 is pulled out of the base 11 and the second magnetic member 24 is aligned within the bottom range of the base 11, the first magnetic member 13 and the second magnetic member 24 attract each other.

[0025] In this embodiment, when the movable box 21 is plugged and used with the base 11, the sides of the first magnetic member 13 facing the second magnetic member 24 repel magnetically, so that the movable box 21 is stably abutted against the locking pin 81, and a locking abutment limit function is formed between the movable box 21 and the base 11, ensuring the stability after the movable box 21 and the base 11 are plugged and locked. In the state where the movable box 21 and the base 11 are unlocked and there is no pressing force (manual pressing), the second magnetic member 24 and the first magnetic member 13 are relatively separated under the magnetic repulsion.

[0026] When the movable box 21 and the base 11 are separated and used, on the one hand, both the movable box 21 and the base 11 can be separately adsorbed on a magnetic mounting structure (magnetic metal plate); On the other hand, when the bottoms of the movable box 21 and the base 11 face each other, they can be cooperatively adsorbed inside and outside a non-magnetic plate (such as a plastic or glass mounting plate), so as to facilitate the installation of the movable box 21 inside the neonatal care box body and the installation of the base 11 outside the neonatal care box body.

[0027] In this embodiment, the movable box 21 includes two usage states: Docking usage state, the movable box 21 is locked with the locking pin 81, and the movable box 21 can be stably locked and installed on the base 11, avoiding the phenomenon of loosening and detachment after the movable box 21 and the base 11 are connected and used. Separation usage state, the movable box 21 is unlocked from the locking pin 81, and the movable box 21 can stably move up and down from the base 11, facilitating the installation or removal between the movable box 21 and the base 11.

[0028] When it is necessary to integrate the movable box 21 and the base 11 for use, directly install the base 11 within the neonatal care range (inside the neonatal care box body), and collect the video images of the neonate through the infrared camera 22 to collect and identify the breathing movements and body temperature of the neonate. When it is necessary to separate and use the movable box 21 and the base 11, first manually twist the movable box 21 to rotate relative to the base 11, so that the locking pin 81 is gradually separated from the switch port 211, and the state between the movable box 21 and the base 11 is switched from the locked state to the unlocked state, which facilitates the separation and use between the movable box 21 and the base 11; it is convenient to install the movable box 21 inside the neonatal care box, and the base 11 is installed outside the neonatal care box, avoiding the base 11 from affecting the newborn during the alarm; it is convenient to separately use the acquisition device and the alarm device, and install the alarm device in the management area of the caregiver.

[0029] Please refer to Figure 4 and Figure 5 As shown in, a pair of docking holes 811 are formed on the locking pin 81, and the first conductive member 812 is integrally installed on the locking pin 81 and within the range of the docking holes 811; the locking connection mechanism 8 further includes a connection plug 82 and a second conductive member 84. The connection plug 82 is fixedly arranged on the movable box 21, and the second conductive member 84 penetrates through the connection plug 82 and is in electrical connection with the first conductive member 812 after contact.

[0030] The docking holes 811 are aligned within the rotation range of the connection plug 82.

[0031] In this embodiment, the first conductive member 812 and the second conductive member 84 include two states; Connection state: The first conductive member 812 is in contact with the second conductive member 84, and the first conductive member 812 provides support for indirectly powering the electronic devices in the movable box 21 through the second conductive member 84; Disconnected state: The first conductive member 812 is separated from the second conductive member 84, and the movable box 21 is powered separately by the power supply module 25.

[0032] During the unlocking process of the locking pin 81 and the movable box 21, the first conductive member 812 and the second conductive member 84 are switched from the connected state to the disconnected state; during the locking process of the locking pin 81 and the movable box 21, the first conductive member 812 and the second conductive member 84 are switched from the disconnected state to the connected state.

[0033] When the connection plug 82 rotates and adjusts following the movable box 21, the connection plug 82 can adaptively insert into the inside of the docking holes 811. While facilitating the locking between the movable box 21 and the base 11, it can also realize the automatic insertion of the first conductive member 812 and the second conductive member 84, facilitating the base 11 to provide indirect power supply support for the use of the movable box 21. Please refer to Figure 4 and Figure 5 A contraction cavity 821 is formed on the connecting plug rod 82. An elastic member 83 elastically connects the connecting plug rod 82 and the second conductive member 84, and the elastic member 83 and the second conductive member 84 are arranged within the range of the contraction cavity 821.

[0034] In this embodiment, the second conductive member 84 penetrates through the connecting plug rod 82 and is movably connected. The edges and corners of the second conductive member 84 are chamfered so that the edges are smooth, facilitating stable contact after the second conductive member 84 is connected to the first conductive member 812.

[0035] The elastic member 83 provides buffer support for the adaptive elastic telescopic adjustment of the second conductive member 84, facilitating the stability when the second conductive member 84 is movably connected to the first conductive member 812, ensuring the stability of the electrical connection after the first conductive member 812 contacts the second conductive member 84, and avoiding loosening of the connection after multiple contacts between the first conductive member 812 and the second conductive member 84.

[0036] Combined with Figure 4 and Figure 7 As shown in FIG. (a), the switch opening 211 has an L-shaped structure. The locking pin 81 rotates relative to the movable box 21 through the switch opening 211, and after rotation, the locking pin 81 is withdrawn from the bottom of the movable box 21.

[0037] Specifically, the switch opening 211 is composed of a vertical unlocking section and a horizontal locking section. The unlocking section penetrates downward through the movable box 21, facilitating the withdrawal of the locking pin 81 from the bottom of the movable box 21. When the locking pin 81 is located in the unlocking section, the movable box 21 and the base 11 are in an unlocked state, facilitating the vertical disassembly between the movable box 21 and the base 11. When the locking pin 81 is located in the locking section, the movable box 21 and the base 11 are in a locked state, maintaining the stability of the connection between the movable box 21 and the base 11.

[0038] When the locking pin 81 is within the range of the locking section, the second magnetic member 24 moves upward under the mutual repulsion of the first magnetic member 13. The second magnetic member 24 drives the movable box 21 to stably abut against the locking pin 81, realizing the stability of the locking after the connection between the movable box 21 and the base 11.

[0039] Please refer to again Figure 2, the neonatal respiration and cry recording device further includes an integrated controller 3, which is installed in the movable box 21. The input end of the integrated controller 3 is electrically connected to the infrared camera 22, the sound collector 23, and the power supply module 25. The output end of the integrated controller 3 is signal-connected to the signal sending device 4. The power supply module 25 indirectly supplies power through the first conductive member 812 in the connected state to the second conductive member 84.

[0040] The integrated controller 3 is used to process the video data collected by the infrared camera 22; The integrated controller 3 is used to process the sound data collected by the sound collector 23; The power supply module 25 facilitates providing backup power storage and usage support for the temporary use of electronic devices in the movable box 21, enabling the movable box 21 to continue to be used for a certain period without direct / indirect power supply support. After use, it needs to be recharged before it can be separated and used again.

[0041] Preferably, the input end of the power supply module 25 is provided with an independent power supply interface.

[0042] The power supply interface facilitates the independent charging of the power supply module 25. After the movable box 21 and the base 11 are separated, the movable box 21 is charged separately through an independent charging cable; this meets the long-term use after the movable box 21 and the base 11 are separated.

[0043] Please refer to again Figure 4 , the locking connection mechanism 8 further includes a signal interface 85 and a signal connector 86. The signal interface 85 is installed on the base 11, and the signal connector 86 is installed on the movable box 21. When the movable box 21 is connected to the base 11, the signal connector 86 is plugged into the signal interface 85; when the movable box 21 is separated from the base 11, the signal connector 86 is pulled out from the signal interface 85.

[0044] In this embodiment, there are two signal connection modes between the signal sending device 4 and the signal transceiver device 5: Wired connection mode, the signal sending device 4 and the signal transceiver device 5 are signal-connected through a wired connection structure, facilitating the wired transmission of data (the signal interface 85 and the signal connector 86 are plugged); Wireless connection mode, the signal sending device 4 and the signal transceiver device 5 are signal-connected through a wireless connection structure, facilitating the wireless transmission of data (the signal interface 85 and the signal connector 86 are separated).

[0045] It is convenient to provide two different signal transmission modes between the movable box 21 and the base 11, which facilitates the wireless signal connection when the movable box 21 and the base 11 are disassembled and used, and facilitates the wired signal connection when the movable box 21 and the base 11 are docked and used. It effectively avoids the problem that the device cannot continue to be used when the single signal transmission mode fails to transmit the signal normally, and improves the fault tolerance rate of the device.

[0046] Please refer to again Figure 4 , the signal interface 85 is inlaid and installed on the locking pin 81, and the signal connector 86 is installed on the connecting plug rod 82; when the connecting plug rod 82 is inserted into the locking pin 81, the signal connector 86 is automatically connected to the signal interface 85; when the connecting plug rod 82 is separated from the locking pin 81, the signal connector 86 is automatically separated from the signal interface 85.

[0047] In this embodiment, the signal interface 85 is in wired signal connection with the signal transceiver device 5; the signal connector 86 is in wired signal connection with the signal sending device 4.

[0048] In this embodiment, there are two usage states between the signal interface 85 and the signal connector 86: Plugged state, the signal interface 85 and the signal connector 86 are plugged together, and the signal sending device 4 and the signal transceiver device 5 are in a wired connection state; Disassembled state, the signal interface 85 and the signal connector 86 are separated, and the signal sending device 4 and the signal transceiver device 5 are in a wireless connection state.

[0049] When the connecting plug rod 82 is inserted into the locking pin 81, the signal interface 85 and the signal connector 86 are automatically plugged together. When the connecting plug rod 82 is separated from the locking pin 81, the signal interface 85 and the signal connector 86 are automatically separated; it is convenient to synchronously switch the signal connection state (from wired state to wireless state or from wireless state to wired state) during the process of switching the connection state between the locking pin 81 and the connecting plug rod 82.

[0050] Finally, during the process of switching from the connected usage state to the separated usage state between the movable box 21 and the base 11, the power supply mode of the movable box 21 is synchronously switched from the indirect power supply mode to the wired power supply mode, and the signal connection mode between the signal sending device 4 and the signal transceiver device 5 is switched from the wired connection mode to the wireless connection mode.

[0051] Please refer to again Figure 2The newborn's breathing and crying recording device also includes a warning light strip 7, which is installed on the top of the base 11. The signal transceiver 5 is connected to the player 6 and the warning light strip 7 by signal. The signal transceiver 5 has a built-in signal processor, and the base 11 is equipped with an independent charging interface.

[0052] After the device is powered on and started normally, the warning light strip 7 emits a yellow light when there is no monitored object; when the newborn is monitored to be in a normal state, the device emits a green light; when the newborn is monitored to be in an abnormal state, the device emits a red light.

[0053] Different colors of light feedback make it easy for caregivers to identify the usage status of the equipment.

[0054] The coordinated use of lighting effects and voice effects facilitates real-time status indication and feedback on the monitoring status of newborns.

[0055] In an optional implementation of this embodiment, the output end of the signal transceiver 5 can be wirelessly connected to a touch screen, and the signal transceiver 5 can conveniently transmit the monitored newborn information to the touch screen for centralized display. When facing the care of multiple newborns, one signal transceiver 5 can be connected to multiple signal sending devices 4, and the warning information sent by multiple signal sending devices 4 can be centrally transmitted to the touch screen for display, which is convenient for the centralized monitoring and management of multiple newborns.

[0056] The working principle of the newborn's breathing and crying recording device provided in this embodiment is as follows: like Figure 6 (a) and Figure 7 As shown in (a), it may be defined that in the initial state, the movable box 21 and the base 11 are in a docking state, the first conductive member 812 and the second conductive member 84 are in a connected state, and the signal connector 86 and the signal interface 85 are in a plugged state; Combined with reference Figure 6 (a) to Figure 6 (b) to Figure 6 (c) and Figure 7 (a) to Figure 7 (b) When the movable box 21 needs to be separated from the base 11, the movable box 21 and the base 11 are manually twisted so that the movable box 21 is twisted clockwise relative to the base 11, so that the locking pin 81 rotates from the locking section to the unlocking section; While the movable box 21 rotates, on the one hand, it synchronously drives the connecting plug rod 82 to separate from the locking pin 81, so that the connecting plug rod 82 synchronously drives the elastic member 83 and the second conductive member 84 to move as a whole, so that the second conductive member 84 separates from the first conductive member 812, and the power supply mode of the movable box 21 is switched from the indirect power supply mode to the direct plug-in power supply mode; On the other hand, the movable box 21 synchronously drives the signal connector 86 to move through the connecting plug rod 82, and the signal connector 86 automatically separates from the signal interface 85, so that the movable box 21 is switched from the wired signal transmission mode to the wireless signal transmission mode; Please refer to Figure 7 Figure (b) to Figure 7 Figure (c). After the movable box 21 is unlocked, the movable box 21 is automatically pushed upward under the mutual repulsion of the second magnetic member 24 and the first magnetic member 13, so that the movable box 21 moves upward relative to the base 11, facilitating the separation between the movable box 21 and the base 11; As shown in Figure 6 Figure (c) and Figure 7 Figure (c), the movable box 21 and the base 11 are in a separated use state, the first conductive member 812 and the second conductive member 84 are in a disconnected state, and the signal connector 86 and the signal interface 85 are in a separated state.

[0057] Finally, while switching from the docking use state to the separated use state between the movable box 21 and the base 11, the switching of the power supply mode and the signal transmission mode is synchronously realized; and after separation, the movable box 21 and the base 11 can be separately installed and used, and can also be fixed inside and outside an installation partition board (non-magnetic plate, plate thickness ≤ 20 mm) after being matched with each other.

[0058] The present invention also provides a crying evaluation system.

[0059] Specifically, the crying evaluation system is integrally installed on the neonatal breathing and crying recording device, and is characterized in that the crying evaluation system includes a collection and recognition module and an early warning and alarm module. The collection and recognition module is signal-connected to the early warning and alarm module. The collection and recognition module is integrally installed on the movable box 21, and the early warning and alarm module is integrally installed on the base 11, facilitating the synchronous recognition, analysis and early warning of children's breathing and crying.

[0060] Specifically, the collection module includes a breathing action collection unit, a sound collection unit, an identification and processing unit and a signal sending unit. The breathing action collection unit, the sound collection unit and the signal transceiver unit are all signal-connected to the identification and processing unit; The respiratory motion acquisition unit integrates an infrared camera, a millimeter-wave radar, and a microphone array. The infrared camera performs video recognition and analysis on the temperature of the newborn, the monitoring of respiratory airflow, and the pixel change in the ROI area of the chest. The millimeter-wave radar penetrates the clothing to monitor the slight movement of the chest and analyzes the respiratory rhythm based on FFT spectrum. The microphone array listens to the breathing sound of the newborn and cooperates with the infrared camera and the millimeter-wave radar to form a multi-modal sensing array for respiratory motion acquisition. The sound acquisition unit includes the aforementioned microphone array, which is also used for the recognition and recording of the crying sound of the newborn. The recognition and processing unit includes respiratory motion recording, respiratory sound recording, generating warning respiratory rules, crying sound type recording, crying sound cycle recording, generating warning crying rules, and real-time monitoring and warning of respiration and crying. The respiratory motion recording is used to input and edit recognizable respiratory motions into the local storage space. The respiratory sound recording is used to input and edit recognizable respiratory sounds into the local storage space. The generating warning respiratory rules automatically generate warning respiratory rules based on the input respiratory motions and respiratory sounds, providing a data basis for the monitoring and warning of the newborn's respiratory motions. The crying sound type recording is used to input and edit recognizable crying sound types into the local storage space. The crying sound cycle recording is used to input and edit recognizable crying sound cycles into the local storage space. The generating warning crying rules automatically generate warning crying rules based on the input crying sound types and crying sound cycles, providing a data basis for the monitoring and warning of the newborn's crying sound types. The real-time monitoring and warning of respiration and crying is used for the analysis of the collected data and the sending of warning signals.

[0061] The warning and alarm module includes a signal transceiver and recording unit, a lighting alarm unit, and a warning broadcast unit. The signal transceiver and recording unit is used to receive and manage the monitoring information sent in real time by the signal sending unit, and judge whether warning and alarm are needed according to the monitoring information. The lighting alarm unit is used to emit light reminders and judge whether the respiratory motions and crying sounds of the newborn are normal according to the lights of different colors. The warning broadcast unit is used to emit warning sounds, which can be music or voice reminders, and broadcast different voice reminders according to the recognized abnormal types.

[0062] In an alternative embodiment of this embodiment, the warning and alarm module further includes a touch display screen, which is used to display alarm information, newborn information, and monitoring images.

[0063] It is convenient and intuitive to understand the current status of the newborn with abnormal alarm. According to the combination of the caregiver's experience and the early warning analysis content, the caregiver can directly edit, update and cancel the alarm information through the touch screen.

[0064] In this embodiment, when the collection and identification module is installed and used, it should be placed inside the neonatal care box, and the care box should be soundproofed from the external environment, and the early warning alarm module should be placed outside the neonatal care box; on the one hand, it can effectively avoid the chain reaction of crying between newborns when multiple newborns are cared for (when one newborn cries, multiple newborns will cry synchronously), and on the other hand, it can reduce the impact of the alarm sound on resting newborns.

[0065] In this embodiment, when caring for multiple newborns, one early warning alarm module can be connected to multiple collection and identification modules, so as to facilitate the display of alarms and alarm information of multiple collection and identification modules through one early warning alarm module.

[0066] Early warning steps: S1, real-time collection of the newborn's breathing movements and crying types; S2, analyze whether the newborn's breathing movements are normal (frequency of chest rise and fall / frequency of breathing sounds); S21, when the breathing action of the newborn changes suddenly and tends to deviate from the safe frequency, the recognition processing unit automatically alarms and sends the alarm information to the receiving terminal (base 11 / mobile phone / ipad, etc.); S22, when the neonate's breathing movements are normal, continue to monitor and record the regularity of the neonate's breathing movements; S3, analyzing whether the cry type of the newborn is normal (based on the identification and comparison of cry characteristics); S31, when the cry type of the newborn is abnormal (hunger / defecation / lack of water), the recognition processing unit automatically alarms and sends the alarm information to the receiving terminal; S32, when the crying type of the newborn is normal, the newborn is relieved and relaxed by playing music or shaking the neonatal intensive care unit until the crying of the newborn stops; if the crying of the newborn does not stop in time within the preset time period, the recognition processing unit automatically alarms and sends the alarm information to the receiving terminal; S4 continuously records and analyzes the breathing and crying behavior characteristics of the newborn, and automatically updates the data in the storage space according to the actual behavior characteristics of the newborn.

[0067] Ultimately, the system can realize the contactless collection of the breathing movements and crying sounds of newborns, and automatically identify, analyze, warn and alarm the types of crying sounds, so as to provide timely and safe care for newborns.

[0068] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the concept of the present invention by using the content of the specification and drawings of the present invention, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present invention.
