Description

Technical Field

[0001] The present invention relates to the field of human health detection, and more specifically, to a wireless sleep breathing monitor. Background Art

[0002] Sleep apnea monitoring is the observation of changes in the user's central nervous system, respiratory system, cardiovascular system and other systems during sleep, in order to meet the needs of clinical diagnosis and efficacy evaluation of sleep apnea disorders. Currently, the more common sleep apnea monitoring devices on the market are medical polysomnography and millimeter wave radar sleep apnea monitoring devices. However, although the medical polysomnography monitoring equipment in the prior art monitors relatively comprehensive human characteristic data, it usually requires complex wiring and fixing devices when used. Users need to wear the sleep monitoring equipment for a long time when sleeping in order to collect and monitor vital sign data. The discomfort of wearing the equipment will affect the sleep and rest of some users, and the installation process is also inconvenient, and it is difficult for users to install and use it independently. The millimeter wave radar sleep breathing monitoring equipment monitors sleep breathing by vibrating the human chest, but the heart rate and nasal breathing of the human body are not synchronously connected during sleep. Sometimes when the heart rate beats, the nasal breathing stops, and a relatively comprehensive sleep breathing data detection cannot be achieved. Therefore, it is of great practical significance to develop a portable, wireless sleep breathing monitor. Summary of the invention

[0003] In view of the problems in the prior art that wired sleep monitoring devices are uncomfortable for users to wear and inconvenient to install, and that wireless sleep breathing monitoring equipment using millimeter wave radar has single data detection, the purpose of the present invention is to provide a wireless sleep breathing monitor.

[0004] To solve the above problems, the present invention adopts the following technical solutions.

[0005] A wireless sleep breathing monitor comprises a monitor housing, a winding part and a monitoring part, wherein the monitor housing is provided with a monitor box cover, a mainboard is installed in the monitor housing, a first connecting wire and a second connecting wire are connected to the mainboard, a wire through hole is opened on the monitor housing, and the second connecting wire is passed through the wire through hole; The winding part is arranged in the housing of the monitor, and the winding part comprises a reel for winding and unwinding the connecting wire 2; The monitoring part is arranged outside the monitor housing, and the connecting wire 1 and the connecting wire 2 are both connected to the monitoring part, and the monitoring part is used to monitor the user's heart rate and nasal breathing frequency.

[0006] Furthermore, a fixing rod 1 and a fixing rod 2 are provided in the monitor housing, and the fixing rod 1 and the fixing rod 2 are provided with a pulley 1 and a pulley 2 respectively, and the connecting wire 2 is wound around the pulley 1 and the pulley 2 in sequence.

[0007] Furthermore, the winding portion further comprises: A mounting frame fixedly mounted in the housing of the monitor, a group of fixed limit plates fixedly connected to the mounting frame, the reel arranged between the group of fixed limit plates, bearings arranged on the fixed limit plates, the reel rotatably connected to the fixed limit plates via the bearings; A driving motor is fixedly mounted on the mounting frame, a gear 1 is coaxially fixedly connected to the output end of the driving motor, a gear 2 is coaxially fixedly connected to the reel, and the gear 1 and the gear 2 are meshed for transmission; A tension sensor is arranged in the housing of the monitor, and a pull rope is arranged between the tension sensor and the second connecting wire.

[0008] Furthermore, the reel is provided with an inlet and an outlet, the diameter of the outlet is larger than the diameter of the inlet, the second connecting wire passes through the inlet and the outlet in sequence, and a limit block is provided on the second connecting wire, the limit block is arranged on the outlet in the reel, and the size of the limit block is larger than the diameter of the outlet.

[0009] Furthermore, a support rod is provided on the outside of the monitor housing, and a support ring is fixedly connected to one end of the support rod away from the monitor housing. The support ring is sleeved on the outside of the second connecting wire, and the part of the second connecting wire that is located between the second pulley and the support ring and is in a horizontal state is coaxially arranged with the wire hole.

[0010] Furthermore, the monitoring unit includes: A sleep monitoring belt and a breathing monitoring patch respectively connected to the connecting wire 1 and the connecting wire 2, wherein the connecting wire 1 and the connecting wire 2 are both provided with an anode connecting wire and a cathode connecting wire; The outer side of the sleep monitoring belt is covered with a sleeve belt, the bottom of the sleeve belt is provided with an adhesive strip and a pin, and the breathing monitoring sticker is provided with an adhesive sheet.

[0011] Furthermore, a control board and a display panel are provided on the monitor housing, an alarm module is provided on the main board, and the control board is respectively connected with the display panel, the tension sensor and the driving motor by electrical signals.

[0012] Compared with the prior art, the present invention has the following beneficial effects: (1) The present application provides a wire hole on the monitor housing, and the diameter of the wire hole is larger than the diameter of the connecting wire 2. The connecting wire 2 is arranged coaxially with the wire hole by connecting a pull rope to the end of a tension sensor. The tension sensor uses a piezoelectric material. This material generates a voltage when subjected to mechanical stress. The magnitude of the voltage is proportional to the applied tension. Therefore, the tightness of the connecting wire 2 exposed outside the monitor housing can be judged in real time by the voltage change, and the voltage is quickly fed back to the control board for a quick response. The control board controls the output end of the drive motor to drive gear 1 and gear 2 to engage and transmit, so that the reel rotates, and the connecting wire 2 is wound or unwound, so that the connecting wire 2 is always arranged coaxially with the wire hole, thereby preventing the user from turning over during sleep, causing the connecting wire to be entangled or the device to be bumped.

[0013] (2) The breathing monitoring patch in the present application bends when at rest, making its voltage sensitivity extremely high. When a thin elastic band is used to hold this standard sensor close to the nose, the breathing monitoring patch is made of soft, breathable material to ensure the user's comfort when wearing it. The sensor in the piezoelectric film can monitor the frequency of the nasal wing beating during breathing. By selecting a very low frequency limit on the electronic interface of the motherboard, the breathing frequency can be observed on the display panel. In order to eliminate the breathing signal and remove certain noise, a filter is applied to obtain a real-time signal to ensure the accuracy of the sleep breathing monitoring device. It can work normally without external power and can meet the needs of a large number of medical applications that require detection of extremely low mechanical vibrations. In addition, the piezoelectric film is relatively durable, can withstand frequent bending, and has a long service life.

[0014] (3) The present application uses adhesive strips and pins to fix the sleeve and the sleep monitoring belt on the sleeve between the mattress and the sheets, so the user does not need to wear it directly, thus avoiding the user having difficulty falling asleep due to wearing discomfort; the user's heart rate and breathing rate are monitored by the sleep monitoring belt and the breathing monitoring patch, and the sleep breathing monitoring is more comprehensive and accurate.

The operation is simple and convenient.

[0019] Embodiment 2, as Figures 3 to 5 FIG. 2 is a second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a winding portion 2 of a wireless sleep breathing monitor. The winding portion 2 is arranged in the monitor housing 1. The winding portion 2 includes a reel 24 for winding and unwinding the connecting wire 113. The winding portion 2 also includes: A mounting frame 21 is fixedly mounted in the monitor housing 1, a group of fixed limit plates 23 are fixedly connected to the mounting frame 21, a reel 24 is arranged between the group of fixed limit plates 23, a bearing 26 is arranged on the fixed limit plates 23, and the reel 24 is rotatably connected to the fixed limit plates 23 through the bearing 26; A driving motor 22 is fixedly mounted on the mounting frame 21, and a gear 1 221 is coaxially fixedly connected to the output end of the driving motor 22. A gear 25 is coaxially fixedly connected to the reel 24, and the gear 1 221 and the gear 2 25 are meshed and transmitted. A fixing rod 1 27 and a fixing rod 28 are provided in the monitor housing 1, and a pulley 1 271 and a pulley 281 are provided in the fixing rod 1 27 and the fixing rod 28 respectively, and the connecting wire 2 113 is wound around the pulley 1 271 and the pulley 2 281 in sequence; a tension sensor 29 is provided in the monitor housing 1, and a pull rope 291 is provided between the tension sensor 29 and the connecting wire 2 113; The reel 24 is provided with an inlet 241 and an outlet 242, the diameter of the outlet 242 is larger than the diameter of the inlet 241, the second connecting wire 113 passes through the inlet 241 and the outlet 242 in sequence, the second connecting wire 113 is provided with a limit block, the limit block is arranged on the outlet 242 in the reel 24, the size of the limit block is larger than the diameter of the outlet 242, a support rod is arranged on the outside of the monitor housing 1, the end of the support rod away from the monitor housing 1 is fixedly connected with a support ring, the support ring is sleeved on the outside of the second connecting wire 113, the part of the second connecting wire 113 located between the second pulley 281 and the support ring in a horizontal state is coaxially arranged with the wire through hole 12; During use: When the user's head moves or rotates during sleep, the connecting wire 113 may still be entangled if no corresponding measures are taken. Therefore, a wire hole 12 is opened on the monitor housing 1, and the diameter of the wire hole 12 is larger than the diameter of the connecting wire 113. The end of the tension sensor 29 is connected to the pull rope 291 to set the connecting wire 113 and the wire hole 12 coaxially. The tension sensor 29 is made of piezoelectric material, which generates voltage when subjected to mechanical stress. The voltage is proportional to the applied tension, so the tightness of the connecting wire 113 exposed outside the monitor housing 1 can be judged in real time through the voltage change, and quickly fed back to the control board for quick response. Since one end of the connecting wire 113 connected to the main board 111 first passes through the wire inlet 241, then passes through the wire outlet 242, and is wound on the reel 24, the diameter of the wire inlet 241 is larger than the diameter of the wire outlet 242, and a limit block is provided at the position of the wire outlet 242 in the reel 24 to prevent the connecting wire 113 wound on the reel 24 from being retracted into the reel 24; At this time, the control panel controls the output end of the drive motor 22 to drive gear 1 21 and gear 2 25 to engage and transmit, so that the reel 24 rotates, and the connecting wire 2 113 is wound or unwound, so that the connecting wire 2 113 is always coaxial with the wire hole 12 to prevent the user from turning over during sleep, which may cause the connecting wire to be entangled or the equipment to be bumped.

[0020] Embodiment 3, as Figure 2 and Figure 6 FIG. 1 is a third embodiment of the present invention. Different from the previous embodiment, this embodiment provides a monitoring unit 3 of a wireless sleep breathing monitor. The monitoring unit 3 is arranged outside the monitor housing 1. The connecting wire 1 112 and the connecting wire 2 113 are both connected to the monitoring unit 3. The monitoring unit 3 is used to monitor the user's heart rate and nasal breathing frequency. The monitoring unit 3 includes: The sleep monitoring belt 31 and the breathing monitoring patch 35 are respectively connected to the connection wire 1 112 and the connection wire 2 113, and the connection wire 1 112 and the connection wire 2 113 are both provided with an anode connection wire 1121 and a cathode connection wire 1122; The outer side of the sleep monitoring belt 31 is provided with a sleeve belt 32, the bottom of the sleeve belt 32 is provided with an adhesive strip 33 and a pin 34, and the breathing monitoring patch 35 is provided with an adhesive sheet; During use: the breathing monitoring patch 35 bends when it is stationary, so that its voltage sensitivity is extremely high. When this standard sensor is pressed against the nose with a thin elastic band, the breathing monitoring patch 35 is made of soft and breathable materials to ensure the user's comfort when wearing it; the sensor in the piezoelectric film can monitor the frequency of the nose wing beating during breathing, and by selecting a very low frequency limit on the electronic interface of the main board 111, the breathing frequency can be observed on the display panel 13. In order to eliminate the breathing signal and remove certain noise, a filter is applied to obtain a real-time signal to ensure the accuracy of the sleep breathing monitoring device; In addition, the strap 32 and the sleep monitoring strap 31 on the strap 32 are fixedly installed between the mattress and the bed sheet by the adhesive strip 33 and the pin 34, and the user does not need to wear it directly, so as to avoid the user having difficulty falling asleep due to discomfort in wearing; the heart rate and breathing rate of the user are monitored by the sleep monitoring strap 31 and the breathing monitoring patch 35. The sleep monitoring strap 31 and the breathing monitoring patch 35 are both made of piezoelectric film. The dynamic signals of the user's heart beat in the chest and nasal breathing are collected by the piezoelectric film and converted into corresponding electrical signals, which are displayed on the display panel 13 on the bedside; sleep breathing monitoring is relatively comprehensive and has a high accuracy rate. The device realizes wireless connection with mobile devices through Bluetooth or Wi-Fi modules to ensure real-time data transmission. The system can actively identify abnormal breathing patterns and send alarms to users to prompt potential health risks (such as sleep apnea). The device has a simple structure and is easy to carry when traveling.

[0021] From the above, we can see that the working principle of this application is as follows: The monitor housing 1 of the sleep breathing monitoring device is placed beside the bed, and the monitor housing 1 is connected with a sleep monitoring belt 31 and a breathing monitoring patch 35 through a connecting wire 112 and a connecting wire 2 113 respectively; the sleep monitoring belt 31 is set between the mattress and the bed sheet, and when the user sits or lies on the bed, the sleep monitoring belt 31 can accurately measure and collect the user's vital characteristics information through the clothes and the bed sheet, and the breathing monitoring patch 35 is attached to the user's nose; the sleep monitoring belt 31 and the breathing monitoring patch 35 are both made of piezoelectric film, and the dynamic signals of the user's chest heart beat and nasal breathing are collected by the piezoelectric film and converted into corresponding electrical signals, which are displayed on the display panel 13 on the bedside; Therefore, by opening a wire hole 12 on the monitor housing 1, and the diameter of the wire hole 12 is larger than the diameter of the connecting wire 113, the connecting wire 113 and the wire hole 12 are coaxially arranged by connecting the pull rope 291 at the end of the tension sensor 29, wherein the tension sensor 29 is made of piezoelectric material, which will generate voltage when subjected to mechanical stress, and the magnitude of the voltage is proportional to the applied tension, so that the tightness of the connecting wire 113 exposed outside the monitor housing 1 can be judged in real time through the voltage change, and quickly fed back to the control board to make a quick response; Since one end of the connecting wire 2 113 connected to the main board 111 first passes through the wire inlet 241, then passes out through the wire outlet 242, and is wound on the reel 24, the diameter of the wire inlet 241 is larger than the diameter of the wire outlet 242, and a limit block is provided at the position of the wire outlet 242 inside the reel 24 to prevent the connecting wire 2 113 wound on the reel 24 from being retracted into the reel 24; at this time, the output end of the driving motor 22 is controlled by the control panel to drive the gear 1 221 to mesh with the gear 2 25, so that the reel 24 rotates, and the connecting wire 2 113 is wound or unwound, so that the connecting wire 2 113 is always coaxial with the wire through hole 12, so as to prevent the user from turning over during sleep, causing the connecting wire to be entangled or the device to be bumped.

[0022] The breathing monitoring patch 35 bends when it is at rest, making its voltage sensitivity extremely high. When this standard sensor is pressed against the nose using a thin elastic band, the breathing monitoring patch 35 is made of soft, breathable material to ensure the user's comfort when wearing it. The sensor in the piezoelectric film can monitor the frequency of the nasal vibration during breathing. By selecting a very low frequency limit on the electronic interface of the main board 111, the breathing frequency can be observed on the display panel 13. In order to eliminate the breathing signal and remove certain noise, a filter is applied to obtain a real-time signal to ensure the accuracy of the sleep breathing monitoring device.

[0023] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto.
