Description

Technical Field

[0001] This invention relates to the field of respiratory monitoring technology, specifically to a monitoring device for human respiration and chest and abdominal movements. Background Technology

[0002] Obese individuals, especially those with significant fat accumulation in the neck, have increased adipose tissue around the neck and pharynx, which can easily lead to narrowing of the upper respiratory tract.

[0003] This upper airway narrowing obstructs airflow during sleep in obese patients, easily triggering sleep apnea. Simultaneously, increased abdominal fat may restrict diaphragmatic movement, affecting lung expansion and increasing respiratory burden. Furthermore, obesity is associated with various metabolic disorders, such as insulin resistance. These metabolic disorders may affect the central nervous system's regulation of respiration through complex mechanisms, further contributing to sleep apnea. Therefore, for obese patients, long-term monitoring of their nocturnal breathing using equipment is essential.

[0004] Among existing devices for measuring respiratory movement, the chest strap respiratory monitoring device is a device that indirectly reflects respiratory activity by measuring chest or abdominal movements. Its working principle is mainly based on the capture and conversion of physical signals generated by respiratory movements by sensors. However, due to the obstruction of neck or chest fat, the detection signal of chest and abdominal movements by the sensors is attenuated, resulting in inaccurate measurement results.

[0005] During the use of chest strap-type respiratory monitoring devices, wearing the chest strap too tightly can restrict the muscles of the chest and abdomen, affecting comfort; wearing it too loosely can easily cause sensor displacement or signal interruption, making it difficult to control the tightness of the chest strap. Secondly, patient discomfort may lead to increased turning over during sleep, potentially increasing the risk of displacement of the original calibration detection points, thus resulting in inaccurate measurement results. Therefore, this invention provides a detection device that can automatically adjust the tightness of the strap, ensuring the accuracy of data acquisition during sensor monitoring and improving the accuracy of respiratory data monitoring. Summary of the Invention

[0006] To address the aforementioned issues, this invention provides a monitoring device for human respiration and chest and abdominal movement. By adjusting the pressure applied during the patient's wearing process, the sensor is positioned to fit snugly against the center of the chest and abdomen, ensuring the accuracy of data acquisition during sensor monitoring and improving the accuracy of respiratory data monitoring.

[0007] To achieve the above objectives, the technical solution of the present invention is as follows: a monitoring device for human respiration and chest and abdominal movement, comprising a housing for mounting a respiration monitoring module, the respiration monitoring module for monitoring deformation signals corresponding to changes in chest and abdominal expansion at fixed points, and binding straps for securing the housing to the patient's chest fixedly connected to both sides of the housing; a driving mechanism for driving the respiration monitoring module to conform to the chest skin is provided inside the housing, and the respiration monitoring module is electrically connected to a signal transmission module for transmitting deformation signals to the outside in real time;

[0008] A first pressure sensor and a second pressure sensor are fixedly connected to the side of the shell near the restraint strap. The first pressure sensor is located above the second pressure sensor. The first pressure sensor is used to detect the first pressure data when the breast fat tissue applies pressure to the shell in real time, and the second pressure sensor is used to detect the second pressure data when the shell applies pressure to the breast skin in real time.

[0009] The signal transmission module is also electrically connected to a control panel, which is used to control the drive mechanism based on changes in the first and second pressure data.

[0010] Furthermore, the shell is pentagonal or elliptical.

[0011] Furthermore, the housing has a hollow cavity that communicates with the outside, the drive mechanism is located inside the hollow cavity, and a shielding membrane for sealing the hollow cavity is fixedly connected inside the housing.

[0012] The drive mechanism includes an arc-shaped block located inside the housing. The respiratory monitoring module is located between the arc-shaped block and the shielding membrane. A first electric actuator and a second electric actuator are respectively hinged to the side of the arc-shaped block away from the shielding membrane. The first electric actuator and the second electric actuator are symmetrically arranged with the arc-shaped block as the center. Both the first electric actuator and the second electric actuator are electrically connected to the control panel.

[0013] The control panel is used to input and store the positional relationship between the first and second electric actuators, and to mark the first and second pressure sensors based on the positional relationship. Then, based on the positional relationship between adjacent first and second electric actuators, a first difference between the associated second pressure data is calculated. This first difference is compared with a set start value. If the first difference is greater than the start value, the associated first pressure data is compared based on the positional relationship between adjacent first and second electric actuators to obtain the bias positional relationship where the first pressure data on one side is less than the first pressure data on the other side. Based on the bias positional relationship, a pressurization command is sent to either the first or second electric actuator. If the first difference is less than the start value, a maintenance command is sent to both the first and second electric actuators.

[0014] Furthermore, a third pressure sensor is provided on the side of the shell near the abdomen. The third pressure sensor is used to detect the third pressure data when the abdominal fat tissue applies pressure to the shell in real time.

[0015] A third electric actuator is hinged to the side of the arc-shaped block away from the third pressure sensor. The third electric actuator is electrically connected to the control panel. The control panel is also used to compare the third pressure data with the set rated value. If the third pressure data is greater than the rated value, a start command is sent to the third electric actuator. If the third pressure data is less than the rated value, a standby command is sent to the third electric actuator.

[0016] Furthermore, the third electric actuator is located between the arc-shaped block and the housing, and the side of the third electric actuator closer to the housing is offset from the center of the arc-shaped block and away from the third pressure sensor.

[0017] Furthermore, the control panel is also used to add a time tag based on the bias position relationship corresponding to the first pressure data on one side being less than the first pressure data on the other side when the first difference is greater than the starting value, and then obtain the correction parameters corresponding to the deformation signal, the first control parameters corresponding to the first electric actuator, and the second control parameters corresponding to the second electric actuator based on the bias position relationship, and send the first control parameters to the first electric actuator and the second control parameters to the second electric actuator.

[0018] Furthermore, the control panel is also used to obtain first pressure data in the opposite direction based on the bias position relationship and convert it into fat weight when the first difference is greater than the start value, calculate the second difference between the fat weight and the set base fat weight, and adjust the pressurization command corresponding to the first electric actuator or the second electric actuator based on the second difference.

[0019] Furthermore, a magnet layer is fixedly connected to the side of the arc-shaped block away from the shielding membrane, and an electromagnet with the same magnetism as the magnet layer is fixedly connected to the inner wall of the shell.

[0020] Furthermore, the control panel is also used to send a verification command to the electromagnet based on the fat weight at the current time when the first difference is greater than the start value. The electromagnet alternately generates magnetism that is opposite to or the same as the magnetic layer based on the verification command. Based on the second pressure data during the maintenance time of the verification command, the fluctuation value of the second pressure data during the maintenance time is calculated. The fluctuation value is compared with the set adjustment value. If the fluctuation value is greater than the adjustment value, an influence label is added to the bias position relationship based on the fluctuation value. If the fluctuation value is less than the adjustment value, a maintenance command is sent to the first electric actuator and the second electric actuator.

[0021] Furthermore, the restraint strap includes a first strap and a second strap, both of which are fixedly connected to the shell, and the ends of the first strap and the second strap away from the shell are fixedly connected with Velcro.

[0022] The above approach has the following beneficial effects:

[0023] 1. This solution uses a drive mechanism to move the respiratory monitoring module, allowing it to fit snugly against the skin and reduce contact with fat deposits in the chest and abdomen. This reduces the impact of fat isolation on signal acquisition during the respiratory monitoring process, thereby improving the accuracy of signal acquisition.

[0024] 2. This solution utilizes the flexible adjustment of the drive mechanism during the respiratory data acquisition process. Compared with traditional chest strap respiratory monitoring devices, it reduces the need to adjust the tightness of the chest strap, improves the comfort of obese patients during wear, and reduces the frequent turning over caused by discomfort, which could lead to displacement of the respiratory monitoring module or signal interruption. This ensures the stability of the respiratory monitoring module's monitoring position at the chest and abdomen, thereby improving the accuracy of respiratory data monitoring.

[0025] 3. In this design, when the patient lies on their side, the chest fat located above the shell falls downwards due to gravity, causing pressure changes on the first and second pressure sensors on the shell. This pressure changes control the drive mechanism to push the respiratory monitoring module into contact with the chest and abdominal skin surface, reducing contact with the fat area and ensuring the accuracy of data acquisition during sensor monitoring, thus improving the accuracy of respiratory data monitoring. Simultaneously, abdominal fat falls downwards due to gravity and accumulates on the bed surface. The more abdominal fat there is, the greater the pushing force on the shell, resulting in a greater displacement of the shell due to the movement of abdominal fat. The pressure changes of the third pressure sensor ensure that the respiratory monitoring module remains in contact with the chest and abdominal skin surface, reducing contact with the fat area.

[0026] Additional aspects and advantages of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0034] The following detailed description illustrates the specific implementation method:

[0035] As attached Figures 1 to 3 As shown: A monitoring device for human respiration and chest and abdominal movement includes a housing 1 for mounting a respiration monitoring module. The housing 1 is pentagonal or elliptical. The pentagonal or elliptical shape of the housing 1 facilitates placement at the junction of the chest and abdominal regions. The recessed area formed by the high sternum, chest fat, and abdominal fat around the housing reduces the displacement of the housing 1, and facilitates contact detection of the skin at the center of the sternum by the respiration monitoring module inside the housing 1.

[0036] The respiratory monitoring module is used to monitor the deformation signals corresponding to changes in chest and abdominal expansion at fixed points. In this embodiment, the respiratory monitoring module is existing technology and will not be described in detail. The housing 1 is fixedly connected to both sides with restraint straps 2 for securing the housing 1 to the patient's chest. The restraint straps 2 include a first strap and a second strap, both of which are fixedly connected to the housing 1. Velcro is fixedly connected to the ends of the first and second straps away from the housing 1. The first and second straps are used to secure the housing 1, ensuring its position remains unchanged. The basic fixing position of the first and second straps is adjusted by adjusting the position of the Velcro to accommodate patients of different body shapes.

[0037] The housing 1 contains a drive mechanism for propelling the respiratory monitoring module to conform to the chest skin. The respiratory monitoring module is electrically connected to a signal transmission module for real-time transmission of deformation signals to the outside environment. The signal transmission module is also electrically connected to a control panel. In this embodiment, the outside environment includes common monitors or mobile devices. The signal transmission module processes the deformation signal through steps such as enhancement, filtering, and conversion, converting the deformation signal into a digital signal. This allows the monitor or mobile device to calculate and convert the digital signal into respiratory parameters such as respiratory rate and tidal volume for graphical display or recording. It also facilitates timely alerts to family members or medical personnel based on the data signals, ensuring the safety of obese patients.

[0038] A first pressure sensor 11 and a second pressure sensor 12 are fixedly connected to the side of the housing 1 near the restraint strap 2. The first pressure sensor 11 is located above the second pressure sensor 12. The first pressure sensor 11 is used to detect the first pressure data when the breast fat tissue applies pressure to the housing 1 in real time, and the second pressure sensor 12 is used to detect the second pressure data when the housing 1 applies pressure to the breast skin in real time.

[0039] The housing 1 has a hollow cavity that communicates with the outside. The drive mechanism is located inside the hollow cavity. A shielding membrane 3 for sealing the hollow cavity is fixedly connected inside the housing 1. The drive mechanism includes an arc-shaped block 31 located inside the housing 1. The respiratory monitoring module is located between the arc-shaped block 31 and the shielding membrane 3. A first electric actuator and a second electric actuator are respectively hinged on the side of the arc-shaped block 31 away from the shielding membrane 3. The first electric actuator and the second electric actuator are symmetrically arranged with the arc-shaped block 31 as the center. Both the first electric actuator and the second electric actuator are electrically connected to the control panel.

[0040] The control panel is used to input and store the positional relationship between the first and second electric actuators, and to mark the first pressure sensor 11 and the second pressure sensor 12 based on the positional relationship. Then, based on the positional relationship between adjacent first and second electric actuators, a first difference between the associated second pressure data is calculated. This first difference is compared with a set start value. If the first difference is greater than the start value, the associated first pressure data is compared based on the positional relationship between adjacent first and second electric actuators to obtain the bias positional relationship where the first pressure data on one side is less than the first pressure data on the other side. Based on the bias positional relationship, a pressurization command is sent to either the first or second electric actuator. If the first difference is less than the start value, a maintenance command is sent to both the first and second electric actuators.

[0041] For example, when the housing 1 is placed in the chest and abdomen position, the restraint strap 2 is used to attach the inside of the housing 1 to the surface of the chest and abdomen skin. Then, the first and second electric push rods push the arc-shaped block 31, causing the respiratory monitoring module on the arc-shaped block 31 to push the shielding membrane 3 to fit against the chest and abdomen surface, facilitating the adhesion of the respiratory monitoring module to the skin near the center of the sternum. During the turning process, due to the influence of the housing 1's own weight and the restraint strap 2, a gap appears between the second pressure sensor 12 on one side of the housing 1 and the chest and abdomen skin, resulting in a decrease in the second pressure data. The second pressure sensor 12 on the other side of the housing 1 is pressed tightly against the chest skin surface due to the influence of the weight of the housing 1, resulting in an increase in the second pressure data.

[0042] Meanwhile, the chest fat tissue falls downwards due to gravity, putting pressure on the first pressure sensor 11 on one side of the housing 1. Based on the data changes of the first pressure sensors 11 on both sides, it is easy to determine the patient's current lateral position, so as to control the first and second electric push rods to push the respiratory monitoring module into contact with the chest and abdominal skin, thereby ensuring the accuracy of data acquisition during the sensor monitoring process.

[0043] The specific implementation process is as follows:

[0044] Due to fat accumulation in the chest and abdomen of obese patients, these areas protrude more than the center of the sternum. When the housing 1 is positioned between the chest and abdomen, the more obese the patient, the easier it is for the accumulated fat in these areas to move and exert pressure on the surface of the housing 1. For patients with milder obesity, the accumulated fat in the abdomen usually creates a concave area at the center of the sternum compared to the sternum, facilitating the placement of the housing 1. When the patient lies flat, the chest fat spreads outwards, preventing pressure on the first and second pressure sensors 11 and 12 at the center. The abdominal fat spreads outwards, and because the body's obesity is often circular or planar, it reduces pressure on the third pressure sensor 13 on the housing 1.

[0045] By utilizing the flexible adjustment of the drive mechanism during the respiratory data acquisition process, compared with traditional chest strap respiratory monitoring devices, the need to adjust the tightness of the chest strap is reduced, improving the comfort of obese patients during wear and reducing the frequent turning over caused by discomfort, which could lead to displacement of the respiratory monitoring module or signal interruption. This ensures the stability of the monitoring position of the respiratory monitoring module at the chest and abdomen, thereby improving the accuracy of respiratory data monitoring.

[0046] When the patient lies on their side, the chest fat located above the housing 1 falls downwards due to gravity, exerting pressure changes on the first pressure sensor 11 and the second pressure sensor 12 on the housing 1. This controls the drive mechanism to push the respiratory monitoring module to adhere to the surface of the chest and abdomen skin, reducing contact with the fat area in the chest and abdomen, thus ensuring the accuracy of data acquisition during sensor monitoring and improving the accuracy of respiratory data monitoring. At the same time, abdominal fat falls downwards due to gravity and accumulates on the surface of the bed. The more abdominal fat there is, the greater the pushing force on the housing 1, resulting in a greater displacement of the housing 1 due to the movement of abdominal fat. The pressure change of the third pressure sensor 13 ensures that the respiratory monitoring module adheres to the surface of the chest and abdomen skin, reducing contact with the fat area in the chest and abdomen. This minimizes the impact of fat isolation on signal acquisition during the respiratory monitoring module's monitoring process, thereby improving the accuracy of signal acquisition.

[0047] In another embodiment, a third pressure sensor 13 is provided on the side of the housing 1 near the abdomen. The third pressure sensor 13 is used to detect the third pressure data when the abdominal fat tissue applies pressure to the housing 1 in real time. A third electric actuator 32 is hinged to the side of the arc-shaped block 31 away from the third pressure sensor 13. The third electric actuator 32 is electrically connected to the control panel. The control panel is also used to compare the third pressure data with the set rated value. If the third pressure data is greater than the rated value, a start command is sent to the third electric actuator 32. If the third pressure data is less than the rated value, a standby command is sent to the third electric actuator 32.

[0048] For example, during the process of fixing the shell 1 with the restraint strap 2, when the patient is lying on their side, the abdominal fat tissue will move to the side of the lying direction due to gravity. The more abdominal fat tissue there is, the greater the pushing force of the abdominal fat tissue on the shell 1, and the larger the area of ​​the shell 1 that may be affected by the movement of the abdominal fat tissue, which affects the monitoring accuracy of the respiratory monitoring module. By controlling the third electric push rod 32, the respiratory monitoring module on the arc block 31 is pushed to keep it in contact with the abdominal skin.

[0049] The third electric actuator 32 is located between the arc-shaped block 31 and the housing 1, with the side of the third electric actuator 32 closer to the housing 1 offset from the center of the arc-shaped block 31 and away from the third pressure sensor 13. This positioning of the third electric actuator 32 allows the respiratory monitoring module on the arc-shaped block 31 to shift towards the third pressure sensor 13 as it moves, ensuring the module remains in contact with the abdominal skin and thus improving the accuracy of respiratory data monitoring.

[0050] In another embodiment, the control panel is also used to add a time tag based on the bias position relationship corresponding to the first pressure data on one side being less than the first pressure data on the other side when the first difference is greater than the start value, and then obtain the correction parameter corresponding to the deformation signal, the first control parameter corresponding to the first electric actuator, and the second control parameter corresponding to the second electric actuator based on the bias position relationship, and send the first control parameter to the first electric actuator and the second control parameter to the second electric actuator.

[0051] For example, when a patient is in a lateral decubitus position, the right side may compress the heart, affecting cardiac output. Interference generated during heartbeat fluctuations can also impact the real-time monitoring of the respiratory monitoring module, necessitating control of the filtering parameters corresponding to the monitored deformation signals. Conversely, the left lateral decubitus position may restrict respiratory depth due to stomach compression of the diaphragm, requiring adjustments to parameters such as signal enhancement and filtering. Optimizing parameters based on changes in position improves the accuracy of monitoring and consequently, the accuracy of subsequent respiratory parameter calculations.

[0052] In another embodiment, the control panel is also used to, when the first difference is greater than the start value, obtain the first pressure data in the opposite direction based on the bias position relationship and convert it into fat weight, calculate the second difference between the fat weight and the set base fat weight, and adjust the pressurization command corresponding to the first electric actuator or the second electric actuator based on the second difference.

[0053] For example, the larger the chest fat tissue, the greater the pressure exerted on the first pressure sensor 11 on the housing 1, resulting in a larger first pressure data. By converting the first pressure data with the fat weight, the area affected by the current patient's chest fat can be determined. The larger the first pressure data, the higher the degree of obesity of the patient, the smaller the skin area between the center of the sternum and the fat tissue on both sides, and the thicker the fat accumulated under the skin. This has a greater impact on the data acquisition during the respiratory monitoring module monitoring process. By adjusting the extension length of the first or second electric push rod, the respiratory monitoring module on the arc block 31 can be kept in close contact with the skin area with less fat thickness for monitoring, thereby improving the accuracy of respiratory data monitoring.

[0054] In other embodiments, a magnet layer is fixedly connected to the side of the arc-shaped block 31 away from the shielding film 3, and an electromagnet with the same magnetism as the magnet layer is fixedly connected to the inner wall of the housing 1. Through the repulsive effect of the electromagnet with the same magnetism as the magnet layer, the repulsive force of magnetic repulsion is used to push the arc-shaped block 31 to push the shielding film 3 to adhere to the skin surface of the chest and abdomen, so as to improve the signal transmission stability of the respiratory monitoring module during the monitoring process, thereby improving the accuracy of respiratory data monitoring.

[0055] The control panel is also used to send a verification command to the electromagnet based on the fat weight at the current time when the first difference is greater than the start value. The electromagnet alternately generates magnetism that is opposite to or the same as the magnetic layer based on the verification command. Based on the second pressure data during the maintenance time of the verification command, the fluctuation value of the second pressure data during the maintenance time is calculated. The fluctuation value is compared with the set adjustment value. If the fluctuation value is greater than the adjustment value, an influence label is added to the bias position relationship based on the fluctuation value. If the fluctuation value is less than the adjustment value, a maintenance command is sent to the first electric actuator and the second electric actuator.

[0056] For example, by using the attraction or repulsion of the magnet layer by an electromagnet, the arc-shaped block 31 vibrates in the chest and abdomen region. The greater the thickness of the chest adipose tissue, the more obvious the attenuation of the vibration force generated by the fat on the arc-shaped block 31, and the smaller the fluctuation value corresponding to the second pressure data monitored by the second pressure data. This allows for the addition of influence labels to facilitate subsequent parameter correction processing based on the fat thickness, thereby improving the accuracy of respiratory data monitoring.

[0057] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
