[0002] Sleep apnea is a common sleep-related disease, mainly manifested as apnea or hypopnea during sleep, which can cause hypoxia, sleep quality decline, and even serious consequences such as cardiovascular diseases. A sleep apnea detector can be used to detect the respiration state of a user. The sleep apnea detector generally records the respiration state of the user by measuring the volume change of the chest or abdomen, and is widely used in sleep research, respiratory function assessment and clinical diagnosis.

[0036] Embodiment one

[0037] The breathing sensing device provided by the present application is used to connect the strap 101. The strap 101 is generally wrapped around the breathing fluctuation part of the user, such as the chest and abdomen. The strap 101 is connected with the breathing sensing device to measure the volume change of the chest or abdomen, so as to record the breathing pattern of the user.

[0038] Reference Figures 1 to 4As shown, the respiration sensing device comprises a protective shell 102 and a sensing assembly 103; at least one end of the bandage 101 is provided with the sensing assembly 103, which can drive the bandage 101 to pull at least one sensing assembly 103 connected with the bandage 101 when the volume changes at the respiration fluctuation part, so that the sensing assembly 103 can detect the respiration condition of the user. The sensing assembly 103 is installed in the protective shell 102, and the protective shell 102 is arranged to effectively protect the internal sensing assembly 103 from the influence of the external environment (such as dust, moisture, etc.). Specifically, the protective shell 102 comprises a base 104 and an upper cover 105, and the upper cover 105 is buckled on the base 104 to fix the sensing assembly 103 in the internal cavity.

[0039] The sensing assembly 103 comprises an elastic inductance detection device 106 and a signal processing module 107; the protective shell 102 is provided with a first opening 108 to enable the bandage 101 to be connected with the elastic inductance detection device 106 in the protective shell 102. The respiration fluctuation part drives the bandage 101 to pull and stretch the elastic inductance detection device 106 to change the inductance of the elastic inductance detection device 106; the signal processing module 107 is electrically connected with the elastic inductance detection device 106 to convert the change of the inductance of the elastic inductance detection device 106 into an electrical signal.

[0040] That is, the stretching caused by the pulling of the bandage 101 is perceived by the change of the elastic inductance detection device 106, so as to convert the movement of the respiration fluctuation part into the change of the inductance. This arrangement can accurately capture the small breathing action and has high sensitivity. Further, the signal processing module 107 can convert the change of the inductance into an electrical signal, further improving the quantization ability of the movement of the respiration fluctuation part.

[0041] Compared with the prior art, the present application changes the structure and packaging method of the sensor, separates the elastic inductance detection device 106 and the signal processing module 107 with higher cost from the bandage 101, integrates the elastic inductance detection device 106 and the signal processing module 107 in the protective shell 102, and the elastic inductance detection device 106 is not easy to be damaged. The structure shortens the length of the elastic inductance detection device 106, reduces the cost and noise, and improves the accuracy and reliability of the monitoring data. Since the bandage 101 and the elastic inductance detection device 106 are independent of each other, the bandage 101 does not need to use elastic material, so that the bandage 101 can use a material with lower cost but stable performance, thereby reducing the research and production cost of the bandage 101.

[0042] In the optional scheme of the embodiment, the protective shell 102 is provided with two first openings 108 arranged oppositely, and the two ends of the bandage 101 are correspondingly arranged in the two first openings and are connected with the sensing assemblies 103; the two sensing assemblies 103 are arranged along a preset direction and are perpendicular to the direction of pulling of the bandage 101.

[0043] In this embodiment, both ends of the strap 101 are equipped with sensing components 103. In practical applications, any one of the sensing components 103, or the superposition of two sensing components 103, can detect the user's breathing. For example, during sleep, when the user turns over and presses on the strap 101, one end of the strap 101 may become fixed in position, and breathing will not move that end of the strap 101. In this case, the sensing component 103 located at the other end of the strap 101 can perform the detection function independently, thereby making the detection process more reliable.

[0044] In addition, such as Figure 3 As shown, the tension generated at both ends of the strap 101 is in opposite directions (arrows in the figure indicate the direction of tension), and the pulling positions at both ends of the strap 101 are opposite, so that the tension generated by the strap 101 will not cause the protective shell 102 to deflect. The two sensing components 103 are arranged perpendicular to the pulling direction (up and down in the figure) and installed in opposite directions. Both ends of the strap 101 can pull the corresponding sensing component 103 without interfering with each other. When the strap 101 is tightened, the sensing components 103 at both ends of the strap 101 can monitor the force at their respective positions, thus more accurately reflecting the force distribution over the entire length of the strap 101, thereby ensuring the accuracy of the detection results.

[0045] Optionally, the elastic inductance detection devices 106 of the two sensing components 103 are connected in series or in parallel.

[0046] In this embodiment, when the elastic inductance detection devices 106 of the two sensing components 103 are connected in series, the sum of the changes in inductance of the two elastic inductance detection devices 106 corresponds to the entire pulling stroke of the strap 101. The signal processing module 107 can convert the sum of inductance into an electrical signal to obtain relevant parameters of the breathing process. When the elastic inductance detection devices 106 of the two sensing components 103 are connected in parallel, the signal processing modules 107 corresponding to the two elastic inductance detection devices 106 can couple and convert the changes in inductance into electrical signals to obtain relevant parameters of the breathing process.

[0047] In an optional embodiment, the sensing component 103 further includes a shielding cover 109; the shielding cover 109 is specifically made of aluminum alloy and is connected to the protective shell 102; the elastic inductance detection device 106 is installed inside the shielding cover 109, and the signal processing module 107 is installed outside the shielding cover 109; the shielding cover 109 is provided with a second opening 110 to allow the elastic inductance detection device 106 to be connected to the signal processing module 107. Figure 4As shown, the shielding cover 109 comprises a groove body 111 and a cover plate 112. The elastic inductance detection device 106 is installed in the groove body 111, and the cover plate 112 is detachably installed at the groove opening of the groove body 111, so as to facilitate the disassembly and maintenance of the internal structure.

[0048] In this embodiment, the elastic inductance detection device 106 is formed by a power coil. The surface of the power coil can be provided with a plating layer to adjust the elasticity, hardness and inductance strength of the elastic inductance detection device 106. The elastic inductance detection device 106 and the signal processing module 107 can be electrically connected through a soft wire or a flexible circuit board penetrating through the second opening 110, so as to convert the pulling stroke of the bandage 101 into an electric signal. The power coil generates a magnetic field. When the bandage 101 pulls the two elastic inductance detection devices 106, the two elastic inductance detection devices 106 cut each other's magnetic induction lines to generate noise. The elastic inductance detection device 106 is installed in the shielding cover 109 in the present application, which can shield the electromagnetic interference between the two elastic inductance detection devices 106, reduce the noise and improve the user's experience.

[0049] In an optional scheme of this embodiment, as shown in Figure 3 The sensing assembly 103 comprises a pull rope 113 and a sliding piece 114. The sliding piece 114 is movably installed in the shielding cover 109. One end of the elastic inductance detection device 106 is connected with the shielding cover 109, and the other end of the elastic inductance detection device 106 is connected with the sliding piece 114. The pull rope 113 is made of an ultra-high molecular weight polyethylene fiber material which is resistant to pulling and friction, so that the pull rope 113 is not easy to be pulled off in a relatively thin size. One end of the pull rope 113 is connected with the shielding cover 109, and the other end of the pull rope 113 penetrates through the second opening 110 and the first opening 108 to be connected with the end of the bandage 101. The sliding piece 114 is provided with a sliding surface, and the pull rope 113 is wound around the sliding surface to pull the sliding piece 114 to reciprocate.

[0050] In this embodiment, one end of the pull rope 113 is a fixed end, and the other end of the pull rope 113 is a movable end. The pull rope 113 is wound around the sliding surface of the sliding piece 114, so that the pull rope 113 and the sliding piece 114 form a structure similar to a movable pulley. When the bandage 101 pulls the sensing assembly 103, the bandage 101 pulls the pull rope 113 to make the pull rope 113 slide on the sliding surface. The distance by which the bandage 101 pulls the pull rope 113 is twice the moving distance of the sliding piece 114, and the moving distance of the sliding piece 114 corresponds to the extension and contraction amount of the elastic inductance detection device 106. In this way, the relatively long pulling stroke of the bandage 101 can be converted into a relatively small extension and contraction amount of the elastic inductance detection device 106, so as to reduce the space occupied by the elastic inductance detection device 106, reduce the size of the shielding cover 109 and the protective shell 102 accommodating the elastic inductance detection device 106, and improve the comfort of the user when wearing.

[0051] In addition, the breathing fluctuation of different users is different, and the breathing fluctuation of the same user in different sleeping positions is also different, and the pulling stroke of the corresponding binding belt 101 is different. The elastic inductance detection device 106 in the above structure has a larger pulling range of the binding belt 101 under the condition of a certain stretching amount, and even if the breathing fluctuation of the user is large, the elastic inductance detection device 106 is not easy to be pulled and damaged, and the applicability of the device is higher.

[0052] Optionally, the sliding piece 114 is provided with a hooking structure 115 to connect the end of the elastic inductance detection device 106. The sliding surface of the sliding piece 114 can be a smooth cylindrical surface, and the sliding piece 114 does not produce rotating movement in reciprocating movement, and the pulling rope 113 can slide on the sliding surface to reduce the friction between the pulling rope 113 and the sliding piece 114. Alternatively, the sliding piece 114 is a roller structure, and the binding belt 101 pulling the pulling rope 113 can drive the sliding piece 114 to reciprocate and synchronously roll.

[0053] Further, the stretching direction of the elastic inductance detection device 106 is the pulling direction of the binding belt 101, and the sliding piece 114 is taken as the rotating center, the pulling ropes 113 on both sides of the sliding piece 114 are kept parallel or have a negative angle, the elastic inductance detection device 106, the sliding piece 114 and the pulling rope 113 occupy a small space in the width direction of the binding belt 101, the structure is more compact, and the miniaturization of the device is facilitated.

[0054] In the optional scheme of the embodiment, a sliding rail 116 is arranged between the shielding cover 109 and the sliding piece 114 to guide the movement of the sliding piece 114, and the guiding direction of the sliding rail 116 is the pulling direction of the binding belt 101. Specifically, the shielding cover 109 is provided with a strip-shaped hole or a strip-shaped groove on the two opposite side walls to form the sliding rail 116, the sliding piece 114 is provided with a connecting shaft, and the two ends of the connecting shaft are arranged in the corresponding strip-shaped hole or strip-shaped groove. When the pulling rope 113 pulls the sliding piece 114, the sliding piece 114 can reciprocate along the length direction of the strip-shaped hole or strip-shaped groove, so that the deviation or inclination of the sliding piece 114 in the movement process is avoided, the influence of external vibration or impact on the sliding piece 114 is reduced, and the measurement accuracy is ensured.

[0055] In the optional scheme of the embodiment, the sensing assembly 103 further includes a rotating piece 117; the rotating piece 117 is rotatably installed at the second opening 110 of the shielding cover 109, and the relative position between the rotating piece 117 and the shielding cover 109 is fixed; the elastic inductance detection devices 106 of the two sensing assemblies 103 are spaced apart by a preset distance; along the preset direction, the rotating piece 117 is located between the sliding piece 114 and the other sensing assembly 103; the rotating piece 117 is provided with a rotating surface; and along the direction away from the binding belt 101, the pulling ropes 113 are sequentially wound on the rotating surface of the rotating piece 117 and the sliding surface of the sliding piece 114.

[0056] Optionally, the two first openings 108 are respectively located on two opposite side walls of the protective shell 102, and in the preset direction, the first openings 108 are located in the middle of the corresponding side walls; the wire exit position of the rotating member 117 is close to the corresponding strap 101, and the wire exit position is opposite to the position of the first opening 108.

[0057] In this embodiment, although the elastic inductance detection device 106 is surrounded by the shielding cover 109, in order to make the wires connected with the elastic inductance detection device 106 and the pull rope 113 pass out, the shielding cover 109 is not a fully closed structure, and a part of the magnetic induction lines will be exposed from the shielding cover 109. In order to reduce the interference between the two elastic inductance detection devices 106, the sliding members 114 connected with the two elastic inductance detection devices 106 are pulled away from each other, so as to increase the distance between the two elastic inductance detection devices 106, thereby reducing the magnetic field interference and noise.

[0058] In addition, the first opening 108 is located in the middle of the side wall, and the protective shell 102 is not easy to overturn when the two ends of the strap 101 generate tension. Since the pull rope 113 passes out from the first opening 108 to connect the strap 101, in order to reduce the friction force of the pull rope 113 at the first opening 108, when the pull rope 113 is led from the rotating member 117 to the first opening 108, it needs to be consistent with the pulling direction of the strap 101. The present application adjusts the extension direction of the pull rope 113 by setting the rotating member 117, so that the pull rope 113 remains consistent with the pulling direction of the strap 101 when it is led from the rotating member 117 to the first opening 108, and the pull rope 113 and the rotating member 117 form a structure similar to a fixed pulley. Under the action of the rotating member 117 and the sliding member 114, the pull rope 113 forms a zigzag extension path, and the pull rope 113 can be wound on the rotating member 117 and the sliding member 114 in turn to pull the elastic inductance detection device 106 to stretch and retract, and the setting of the rotating member 117 increases the distance between the two sliding members 114. And the total link friction of the pull rope 113 is low, so as to ensure the sensitivity of signal monitoring.

[0059] Specifically, taking the rotating member 117 as the rotation center, the pull ropes 113 on both sides of the rotating member 117 remain parallel or have a negative angle, the elastic inductance detection device 106, the sliding member 114, the rotating member 117 and the pull rope 113 occupy a small space in the width direction of the strap 101, and the structure is more compact, which is beneficial to the miniaturization of the device.

[0063] In this embodiment, the end of the bandage 101 is provided with the limiting member 118 outside the first opening 108, when the elastic inductance sensing device 106 is retracted, the limiting structure can abut against the outside of the protective shell 102, thereby limiting the shortest length of the elastic inductance sensing device 106, and the elastic inductance sensing device 106 is stretched and retracted with the position as the reference position, thereby ensuring the consistency of each detection.
