Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to a monitoring device and an application thereof. Background Art

[0002] Obstructive sleep apnea (OSA) is a chronic disease in which the upper airway collapses during sleep. The diagnosis of OSA is made through a polysomnographic test that records hypopnea or apnea during sleep, as well as a history of daytime symptoms. Most OSA is considered mild to moderate. Common treatments include the use of negative pressure ventilators and hypoglossal nerve stimulation. Because the occurrence of apnea events varies from person to person, the physiological state of the human body needs to be monitored before these treatments are implemented to determine the specific occurrence of individual apnea events so that appropriate treatment can be given.

[0003] Currently, there are portable solutions that use smaller wearable monitors to monitor human body conditions using the impedance measurement method of electrocardiogram. However, smaller monitors are not easy to arrange electrodes for measuring impedance, resulting in poor impedance data collection results. Utility Model Content

[0004] Since the existing monitors have the disadvantage of poor impedance data collection effect, it is necessary to provide a monitoring device and an application thereof.

[0005] An applicator that connects to multiple contacts on a monitor, including:

[0006] An outer layer, the outer layer is used to be attached to the human epidermis;

[0007] an inner layer, the inner layer being fixedly connected to the outer layer, the inner layer having a connecting portion and a plurality of extending portions surrounding the connecting portion; and

[0008] A plurality of measuring electrodes, one end of the measuring electrode is fixedly arranged on the connecting portion for connecting to the contact of the monitor, and the other end of the measuring electrode is fixedly arranged on the extending portion for contacting with the human body epidermis to increase the distance between measuring points.

[0009] With this arrangement, using the patch as a reference, the actual measuring point position of the monitor is transferred from the connecting portion of the inner layer to the extending portion of the inner layer, which increases the measuring point spacing of the monitor, thereby improving the accuracy of the measurement results. In addition, the patch fits the human body, and the measuring points do not have to be coplanar, which also ensures the stability of the electrical connection between the contacts and the human epidermis, thereby ensuring the accuracy of the measurement data.

[0010] In one embodiment, the measuring electrode includes a first electrode located at the connecting portion, a second electrode located at the extending portion, and a conductor located between the outer layer and the inner layer, and two ends of the conductor are electrically connected to the first electrode and the second electrode respectively.

[0011] With this arrangement, the conductor of the measuring electrode is wrapped by the outer layer and the inner layer, which can reduce the interference of external factors such as body fluids, water vapor or bumps on the conductor, thereby ensuring the stable transmission of electrical signals.

[0012] In one embodiment, the inner layer has a first mounting hole corresponding to the connecting portion to expose the first electrode, and the outer layer has a second mounting hole corresponding to the connecting portion to expose the second electrode.

[0013] With such an arrangement, the conductor can be directly electrically connected to the first electrode and the second electrode respectively through the first mounting hole and the second mounting hole, without having to go around to the side of the inner layer facing the monitor or to the side of the outer layer facing the human epidermis, thereby shortening the length of the conductor and avoiding circuit breakage caused by damage to the conductor during use due to bending.

[0014] In one embodiment, the inner layer includes a mounting plate having the first mounting hole and an inner sticker adhered to the side of the mounting plate facing away from the outer layer, the mounting plate is fixedly connected to the outer layer, the inner sticker covers the mounting plate and is adhered to the outer layer, and the inner sticker is provided with a window corresponding to the connecting portion.

[0015] With this arrangement, the mounting plate is wrapped and fixed by bonding the inner and outer layers, which is beneficial to protecting the mounting plate. A window is opened in the inner sticker to expose the first electrode and the mounting plate, which facilitates the electrical connection between the monitor and the first electrode and the fixed connection between the monitor and the mounting plate.

[0016] In one embodiment, the mounting plate includes a substrate and an insulating protective sheet, the substrate includes a connecting plate located at the connecting part and a plurality of extension plates located at the extension part and integrally connected to the connecting plate, the first electrode is fixedly connected to the connecting plate, the second electrode is fixedly connected to the extension plate, and the insulating protective sheet is fixedly connected to a side of the connecting plate facing away from the outer layer.

[0017] With such arrangement, the substrate can carry thinner conductors and also play a certain protective role, while the insulating protection sheet mainly protects the substrate to avoid damage to the substrate.

[0018] In one embodiment, the first electrode is conductive foam.

[0019] With such arrangement, the conductive foam has good softness and elasticity. When the detector and the patch are bonded together, even if there is a gap between the conductive contacts of the patch and the monitor, good contact can be ensured due to the deformation and elasticity of the conductive foam.

[0020] In one embodiment, the second electrode is made of a hydrogel.

[0021] With such a configuration, the first electrode can fit well with human skin by utilizing the good flexibility of the hydrogel component, thereby eliminating the gap and improving the stability and accuracy of data collection.

[0022] In one embodiment, the conductor is a flexible printed circuit board.

[0023] With this arrangement, the flexible printed circuit board can fit the surface of the human body with the inner and outer layers, while also ensuring the stability of current transmission.

[0024] The present application also provides a monitoring device, comprising:

[0025] Monitors; and

[0026] As in the patch mentioned above, the connecting portion of the patch is fixedly connected to the monitor.

[0027] With such an arrangement, in actual use, the monitor is fixed to the human epidermis together with the patch, facilitating real-time monitoring.

[0028] In one embodiment, the monitoring instrument includes an instrument body, a sensor fixedly connected to the instrument body toward the connecting part, and a plurality of contacts fixedly connected to the instrument body toward the connecting part, the contacts are electrically connected to the measuring electrodes of the patch, the patch is also provided with a clearance hole corresponding to the sensor, the sensor is inserted into the clearance hole and is used to contact the human epidermis.

[0029] In this way, the arrangement of the clearance hole on the patch enables the sensor to contact the human body, thereby facilitating the start or stop of the monitoring function. BRIEF DESCRIPTION OF THE DRAWINGS

[0047] Obstructive sleep apnea (OSA) is a chronic disease in which the upper airway collapses during sleep. The diagnosis of OSA is made through a polysomnographic test that records hypopnea or apnea during sleep, as well as a history of daytime symptoms. Most OSA is considered mild to moderate. Common treatments include the use of negative pressure ventilators and hypoglossal nerve stimulation. Because the occurrence of apnea events varies from person to person, the physiological state of the human body needs to be monitored before these treatments are implemented to determine the specific occurrence of individual apnea events so that appropriate treatment can be given.

[0048] Currently, there are portable solutions that use smaller wearable monitors to measure ECG using impedance to monitor human status. However, smaller monitors are not easy to arrange the electrodes used to measure impedance, resulting in poor impedance data collection. When measuring impedance, the larger the spacing, the greater the impedance between the measurement points, the greater the rate of change, and it is less susceptible to interference from factors such as body composition, skin condition, and temperature. Therefore, the larger the spacing between the impedance measurement contacts, the more accurate the measurement results.

[0049] Since the existing monitors have the disadvantage of poor impedance data collection effect, it is necessary to provide a monitoring device and patch that can improve data collection accuracy.

[0050] See also Figures 1 to 5 , Figure 1 Schematic diagram of the structure of a monitoring device in an embodiment of the utility model. Figure 2 for Figure 1 The structural diagram of the monitor 50 is shown in FIG. Figure 3 for Figure 1 Schematic diagram of the structure of the dressing. Figure 4 for Figure 3 Schematic diagram of the bottom structure of the dressing shown, Figure 5 for Figure 4 The illustrated structure is a schematic diagram of the dressing with the outer layer 20 removed.

[0051] A monitoring device provided in the present application includes an application and a monitor 50. Specifically, the monitor 50 includes an instrument body 51, a sensor 53 fixedly connected to the instrument body 51, and a plurality of contacts 52 fixedly connected to the instrument body 51 and arranged around the sensor 53. The application includes an outer layer 20 for adhering to the human epidermis, an inner layer 10 for connecting to the monitor 50, and a plurality of measuring electrodes 30 installed on the inner layer 10. The inner layer 10 has a connecting portion 101 and a plurality of extending portions 102 surrounding the connecting portion 101. One end of the measuring electrode 30 is fixedly arranged on the connecting portion 101 and used to connect to the contact 52. The other end of the measuring electrode 30 is fixedly arranged on the extending portion 102 for contacting with the human epidermis. The application also has a clearance hole 40 corresponding to the sensor 53. The sensor 53 is passed through the clearance hole 40 and used to abut against the human epidermis. Taking the patch as a reference, after such setting, the actual measuring point position of the monitor 50 is transferred from the connecting portion 101 of the inner layer 10 to the extending portion 102 of the inner layer 10, that is, the measuring point spacing of the monitor 50 is increased, thereby improving the accuracy of the measurement result; in addition, the patch fits the human body, and the measuring points do not have to be arranged in the same plane, which also ensures the stability of the electrical connection between the contact 52 and the human epidermis, thereby ensuring the accuracy of the measurement data.

[0052] See also Figure 2 Optionally, in an embodiment provided in the present application, the number of contacts 52 is three, two of which are positive electrodes and negative electrodes, respectively, and the other electrode is used to provide additional data reference.

[0053] Please also read Figure 5 , Figure 6 and Figure 7 , Figure 6 for Figure 5 A schematic structural diagram of the middle substrate 121, Figure 7 for Figure 5 Schematic diagram of the structure of the measuring electrode 30. Specifically, the measuring electrode 30 includes a first electrode 31 located at the connecting portion 101, a second electrode 32 located at the extending portion 102, and a conductor 33 located between the outer layer 20 and the inner layer 10, and the two ends of the conductor 33 are electrically connected to the first electrode 31 and the second electrode 32 respectively. In this way, the conductor 33 of the measuring electrode 30 is wrapped by the outer layer 20 and the inner layer 10, which can reduce the interference of external factors such as body fluids, water vapor or bumps on the conductor 33, thereby ensuring the stable transmission of electrical signals.

[0054] Optionally, in one embodiment provided in the present application, the first electrode 31 is a conductive foam. The conductive foam is used to electrically connect the impedance measurement contact 52 at the bottom of the monitor 50. Compared with conventional electrode sheets or other conductive materials, the conductive foam has good softness and elasticity. When the detector and the patch are bonded, even if there is a gap between the patch and the conductive contact 52 of the monitor 50, good contact can be ensured due to the deformation and elasticity of the conductive foam.

[0055] Optionally, in an embodiment provided in the present application, the second electrode 32 is a hydrogel. When the electrode sheet is attached to the human body, a gap is likely to be generated, which not only easily causes the resistance at the electrode to increase, but also easily allows body fluid to flow in, causing the resistance there to shift, thereby affecting the measurement. In the present application, by utilizing the good flexibility of the hydrogel, the first electrode 31 can be well attached to the human skin, so that the gap can be eliminated, thereby improving the stability and accuracy of data acquisition.

[0056] Optionally, in an embodiment provided in the present application, the conductor 33 is a flexible circuit board. Since the electrode is in contact with one side of the human body, the impedance measurement contact 52 of the monitor 50, the conductive foam, the conductor 33, and the hydrogel component sequentially form a conductive loop so as to collect human body impedance data. The flexible circuit board can be attached to the surface of the human body with the inner layer 10 and the outer layer 20, and the stability of current transmission is also ensured.

[0057] Please also read Figure 3 , Figure 4 and Figure 5 Preferably, in an embodiment provided by the present application, the inner layer 10 has a first mounting hole 103 corresponding to the connection portion 101 to expose the first electrode 31, and the outer layer 20 has a second mounting hole 201 corresponding to the connection portion 101 to expose the second electrode 32. In this way, the conductor 33 can be directly electrically connected to the first electrode 31 and the second electrode 32 through the first mounting hole 103 and the second mounting hole 201 respectively, without having to go around to the side of the inner layer 10 facing the monitor 50 or the side of the outer layer 20 facing the human epidermis, which shortens the length of the conductor 33 and avoids the conductor 33 bending and being damaged during use. Breaking the circuit.

Preferably, in one embodiment provided in the present application, the inner layer 10 includes a mounting plate 12 having a first mounting hole 103 and an inner sticker 11 adhered to the side of the mounting plate 12 facing away from the outer layer 20. The mounting plate 12 is fixedly connected to the outer layer 20. The inner sticker 11 covers the mounting plate 12 and is adhered to the outer layer 20. The inner sticker 11 is provided with a window 111 corresponding to the connecting portion 101. It is worth mentioning that in the present application, the outer layer 20 is an outer sticker 21 with adhesive on both sides, and the inner sticker 11 is provided with adhesive on the side facing the mounting plate 12. The mounting plate 12 is wrapped and fixed by bonding the inner sticker 11 and the outer sticker 21, which is beneficial to protecting the mounting plate 12. The window 111 is provided in the inner sticker 11 to expose the first electrode 31 and the mounting plate 12, which facilitates the electrical connection between the monitor 50 and the first electrode 31 and the fixed connection between the monitor 50 and the mounting plate 12.

[0059] Please read further Figure 6 and Fig. 9 , Fig. 9 for Figure 3 Schematic diagram of the structure of the insulating protective sheet 122. Optionally, in an embodiment provided in the present application, the mounting plate 12 includes a substrate 121 and an insulating protective sheet 122, the substrate 121 includes a connecting plate 1211 located at the connecting portion 101 and a plurality of extension plates 1212 located at the extension portion 102 and integrally connected to the connecting plate 1211, the first electrode 31 is fixedly connected to the connecting plate 1211, the second electrode 32 is fixedly connected to the extension plate 1212, and the insulating protective sheet 122 is fixedly connected to the side of the connecting plate 1211 away from the outer layer 20. It is worth mentioning that the substrate 121 is also made of insulating material, just like the insulating protective sheet 122, which can play an insulating effect on the conductive device, and can also play a certain protective role for the thinner conductor 33. The insulating protective sheet 122 mainly protects the substrate 121 to prevent damage to the substrate 121. In order to facilitate the connection between the application and the monitor 50, a backing adhesive or the like can be set on the side of the insulating protective sheet 122 close to the monitor 50 for bonding.
