Description

Monitoring device Technical Field

[0001] The present disclosure relates to the field of biomedical engineering industry, and in particular to a monitoring device. Background Art

[0002] Diabetes is a common chronic disease, which is generally caused by insufficient insulin in the body or poor insulin effect. When blood sugar levels are at a high level for a long time, it may lead to other complications and affect physical health, so it is particularly important to monitor blood sugar concentration in real time. CGM (Continuous Glucose Monitoring) is a continuous blood sugar monitoring technology, which generally includes a sensor component and an applicator that is electrically connected to the sensor component and applied to the user's body surface. The sensor component can be used to obtain analyte information (for example, glucose concentration) in the user's body, and send it to the user's smart device or terminal by the applicator, so that the user can keep abreast of his or her own blood sugar level. Among them, the sensor component can generally be divided into a sensor part implanted under the user's skin (which can be simply referred to as the implant part) and a sensor part that is not implanted under the user's skin (which can be simply referred to as the connecting part). The connecting part has a number of sensor electrical contacts, which are used to electrically connect to the circuit board on the applicator to transmit electrical signals.

[0003] In the prior art, connectors are typically used to stabilize the connection and provide a certain degree of sealing. These connectors are used to electrically connect the sensor to the circuit board. Typically, the connectors and circuit board are located on the upper shell of the applicator, while the sensor assembly is positioned in a corresponding position on the lower shell of the applicator. When the upper and lower shells are joined, the connectors compress the connection and electrically connect the connection to the circuit board, allowing for signal transmission.

[0004] However, in the above technology, if the upper and lower shells become loose, the connector may separate from the connection part, exposing the electrical contacts of the connection part. If the exposed electrical contacts are affected by external factors (for example, exposure to water or a humid environment), it may cause product failure. In addition, if the connector is not in close contact with the connection part, the connection part is difficult to maintain stability, which may cause the sensor to fall off. Summary of the Invention

[0005] The present disclosure is proposed in view of the above-mentioned state of the prior art, and its purpose is to provide a monitoring device capable of improving the sealing and stability of a sensor.

[0006] To this end, the present disclosure provides a monitoring device, which is applied to the host's body surface to monitor the host's physiological information, including a sensor, a connector, a first shell, a fixing member and a second shell; the sensor includes a connecting part and an implantable part that can be placed under the host's skin, and the connecting part has an electrical contact; the sensor is electrically connected to the connector through the electrical contact; the first shell has a accommodating portion for accommodating the connector and the connecting part; the fixing member is configured to fix the connector and the connecting part in the accommodating portion; the second shell includes a circuit structure electrically connected to the connector.

[0007] In the monitoring device disclosed herein, the connecting portion of the sensor is electrically connected to the circuit structure of the second shell through a connector, and a fixing member fixes the connecting body and the connecting portion to the housing portion of the first shell. In this case, the connector can prevent the electrical contacts of the connecting portion from being exposed (that is, the connecting portion remains sealed), and when the first shell and the second shell become loose or separated, the negative impact of the electrical contacts of the connecting portion coming into contact with the external environment (for example, failure of the connecting portion or contamination) can be reduced. In addition, the fixing member can stably maintain the connecting body and the connecting portion in the housing portion, reduce the loosening of the connecting body and the connecting portion, and at the same time, make the connection between the connecting body and the connecting portion tighter, thereby further reducing the exposure of the electrical contacts, and further improving the sealing of the connecting portion of the sensor.

[0008] Additionally, in the monitoring device of the present disclosure, the connector optionally includes conductive bodies aligned with the electrical contacts and having the same number of conductive bodies as the electrical contacts, one end of each conductive body being connected to the electrical contacts, and the other end of each conductive body being connected to the circuit structure. In this case, since sensors generally transmit electrical signals via electrical contacts, by providing conductive bodies aligned with the electrical contacts and having the same number of conductive bodies, the electrical signal from each electrical contact in the sensor can be transmitted to the circuit structure via the corresponding conductive body, thereby reducing current instability and improving the reliability and stability of the electrical connection between the sensor and the circuit structure.

[0009] In addition, in the monitoring device of the present disclosure, optionally, the connector includes an inner cavity and at least one pivot portion, the at least one pivot portion being used to control the opening or closing of the connector, and the connector is configured to receive the conductor into the inner cavity in the open state. In this case, the connector can be controlled to open to facilitate manipulation of the conductor (e.g., placement or replacement of the conductor), while the connector can be controlled to close to provide greater stability after placement of the conductor into the inner cavity of the connector.

[0010] Additionally, in the monitoring device of the present disclosure, the upper end of the fixing member may optionally have a hollow structure, through which the conductor is at least partially exposed for electrical connection with the circuit structure. In this case, the conductor within the connector can be more fully in contact with the circuit structure without affecting the fixing effect of the fixing member on the connector.

[0011] Additionally, in the monitoring device of the present disclosure, the receiving portion may optionally have at least one snap-fit ​​protrusion, and the sidewall of the fixing member may have a snap-fit ​​groove that matches the snap-fit ​​protrusion, wherein the snap-fit ​​groove engages with the snap-fit ​​protrusion to engage the fixing member with the receiving portion. In this case, the fixing member and the receiving portion can be more tightly coupled, thereby improving the stability of the connection between the connector and the connecting portion provided in the receiving portion.

[0012] In addition, in the monitoring device of the present disclosure, optionally, the first housing has a first through hole, and the implantable portion extends outwardly along the first through hole. In this case, when the monitoring device or the first housing is applied to the body surface of the host, the implantable portion of the sensor can be placed subcutaneously in the host.

[0013] Additionally, in the monitoring device of the present disclosure, the connector optionally includes at least one pair of sheet structures disposed opposite each other, each sheet structure having a second through hole, and the receiving portion includes a column extending through the second through hole to connect to the sheet structures. In this case, by connecting the column through the second through hole to the sheet structure, the connector and the receiving portion are securely connected, thereby improving the stability of the connector within the receiving portion.

[0014] Additionally, in the monitoring device disclosed herein, the end surface where the connector and the fixture meet can optionally include a flange, wherein the flange is elastic. In this case, when the connector and the fixture meet, the fixture compresses the flange, causing it to deform, thereby applying greater pressure to the bonded parts and tightening the bond. Furthermore, the deformation of the flange fills any gaps created during bonding, further enhancing the tightness of the bond.

[0015] In addition, in the monitoring device disclosed herein, the connecting portion and the connecting body optionally match the inner contour of the receiving portion; and the inner contour of the sidewall of the fixing member matches the outer contour of the receiving portion. In this case, loosening of the connecting body and the connecting portion within the receiving portion can be reduced, thereby improving the stability of the connecting body and the connecting portion. Furthermore, the fixing member and the receiving portion can be more tightly coupled, while also reducing assembly errors, thereby improving the ease of assembly of the fixing member and the receiving portion.

[0016] Additionally, in the monitoring device of the present disclosure, the second housing can optionally be configured to abut the fixing member when coupled to the first housing. In this case, the second housing can exert an action on the fixing member when coupled to the first housing, thereby causing the fixing member to further compress the connector, thereby improving the stability of the connector and the connected portion. Furthermore, since the connector and the connected portion are more tightly connected, the sealing of the connected portion can be improved.

[0017] According to the present disclosure, a monitoring device can be provided that improves the sealing performance and stability of a sensor. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] 3A and 3B , the monitoring device 1 may include a first housing 10. In some examples, referring to FIG3A and 3B , the monitoring device 1 may include a second housing 20. In some examples, the first housing 10 may be detachably assembled with the second housing 20.

[0041] In some examples, the first housing 10 may have a base plate 11, which may be applied to the body surface of the host 6. In some examples, the first housing 10 may be used to house a sensor 30. Specifically, in some examples, the base plate 11 may be used to house the sensor 30. In some examples, the sensor 30 may include an implantable portion 31 that may be placed subcutaneously in the host 6.

[0042] In some examples, the first housing 10 may have a first through hole 12. In some examples, the first through hole 12 may be disposed on the bottom plate 11 of the first housing 10. In some examples, the position of the first through hole 12 on the bottom plate 11 may match the position of the implant portion 31 of the sensor 30. In some examples, the position of the first through hole 12 on the bottom plate 11 may overlap with the position of the implant portion 31 of the sensor 30.

[0043] In some examples, the implant portion 31 may extend outward along the first through hole 12. In this case, when the monitoring device 1 or the first housing 10 is applied to the body surface of the host 6, the implant portion 31 of the sensor 30 can be placed under the skin of the host 6.

[0044] In some examples, the implant portion 31 may include a sensing layer, and the sensing layer may be configured to react with the analyte to obtain analyte information.

[0045] 3B , the first housing 10 may include a first sidewall 13. The first sidewall 13 may be connected to the bottom plate 11. In some examples, the first sidewall 13 may be configured to extend in a direction away from the host 6.

[0046] In some examples, the first housing 10 may include a snap-fitting slot 14 (see FIG. 3A and FIG. 3B ), and the snap-fitting slot 14 may be provided on the first sidewall 13. In some examples, the snap-fitting slot 14 may be a square hole, a round hole, or an elliptical hole.

[0047] In some examples, the first housing 10 may include a pressing portion 15 (see Figures 3A and 3B), which may be provided on the first sidewall 13. In some examples, the pressing portion 15 may be configured to couple or separate the first housing 10 from the second housing 20. Specifically, the pressing portion 15 may be configured such that when an action is applied to the pressing portion 15, the first housing 10 may couple or separate from the second housing 20.

[0048] In some examples, the second housing 20 may include a second sidewall 21 (see FIG. 3B ) adapted to the first sidewall 13 . Specifically, the first sidewall 13 may be fully or partially coupled to the second sidewall 21 to combine the first housing 10 with the second housing 20 .

[0049] 3B , the second housing 20 may include a first edge protrusion 22 and a second edge protrusion 23 . The first edge protrusion 22 and the second edge protrusion 23 may be provided on the second sidewall 21 .

[0050] In some examples, the first edge protrusion 22 can be configured to engage with the engaging groove 14. In some examples, the first edge protrusion 22 can be inserted into the engaging groove 14 to engage with the engaging groove 14. In this way, the first housing 10 and the second housing 20 can be coupled to each other.

[0051] In some examples, the second edge protrusion 23 can be configured to engage with the pressing portion 15. In some examples, the pressing portion 15 can include a first end 150 (see FIG. 3B ) configured to engage with the second edge protrusion 23. The end surface of the first end 150 can conform to the shape of the second edge protrusion 23.

[0052] In some examples, the pressing portion 15 may include a second end 151, and the second end 151 may be configured to control the coupling state between the first end 150 and the second edge protrusion 23. In some examples, the coupling state may include a first state indicating that the second edge protrusion 23 is engaged with the first end 150 and a second state indicating that the second edge protrusion 23 is loose from the first end 150.

[0053] In some examples, the combined state may be changed by applying an action to the second end 151 of the pressing portion 15 , that is, the first state and the second state may be converted to each other by applying an action to the second end 151 of the pressing portion 15 .

[0054] In some examples, the second housing 20 may include a circuit structure. In some examples, the second housing 20 may include a circuit structure electrically connected to the sensor 30. In some examples, the circuit structure may include an electronic module that may be configured to process the electrical signal from the sensor 30 that represents the analyte information. In some examples, the electronic module may be configured to transmit the analyte information to the smart terminal of the host 6. In this case, the host 6 can easily obtain its own analyte information, thereby enabling real-time monitoring of its own physiological parameters.

[0055] In some examples, the circuit structure may include a power module. The power module may be configured to provide power to the monitoring device 1 to enable the monitoring device 1 to operate normally. In some examples, the power module may be a rechargeable battery.

[0056] In some examples, the second housing 20 can be configured to abut the fixing member 50 when coupled to the first housing 10. In this case, the second housing 20 can exert an action on the fixing member 50 when coupled to the first housing 10, thereby enabling the fixing member 50 to further compress the connector 40, thereby improving the stability of the connector 40 and the connecting portion 32. Furthermore, since the connection between the connector 40 and the connecting portion 32 is more tightly coupled, the sealing performance of the connecting portion 32 can be improved.

[0057] 4A and 4B , the first housing 10 may have a receiving portion 16. The receiving portion 16 may be configured to receive the connecting body 40 and the connecting portion 32.

[0058] 4B , the sensor 30 may include a connecting portion 32. The connecting portion 32 may be connected to the implant portion 31.

[0059] In some examples, the connection portion 32 can have electrical contacts. In some examples, the connection portion 32 can have at least one electrical contact. For example, the connection portion 32 can have one, two, or three electrical contacts.

[0060] In some examples, the sensor 30 can be electrically connected to the connector 40 via electrical contacts. In other words, in some examples, the electrical signal collected by the sensor 30 and used to represent the analyte information can be transmitted to the circuit structure via the connector 40.

[0061] In some examples, the connecting portion 32 can match the inner contour of the receiving portion 16. In some examples, the connecting body 40 can match the inner contour of the receiving portion 16.

[0062] In some examples, the connecting portion 32 and the connecting body 40 can match the inner contour of the receiving portion 16. In some examples, matching can mean that the outer periphery of the connecting portion 32 and the connecting body 40 can fit closely with the inner contour of the receiving portion 16. In this case, loosening of the connecting body 40 and the connecting portion 32 within the receiving portion 16 can be reduced, thereby improving the stability of the connecting body 40 and the connecting portion 32.

[0063] In some examples, the inner contour of the side wall of the fixing member 50 can match the outer contour of the receiving portion 16. In this case, the fixing member 50 and the receiving portion 16 can be more tightly combined, and at the same time, the error during assembly can be reduced, thereby improving the convenience of assembling the fixing member 50 and the receiving portion 16.

[0064] In some examples, the connector 40 may include at least one conductive channel, and a conductive material may be disposed in the conductive channel. In other words, the conductive material may be filled into the conductive channel.

[0065] In some examples, the second housing 20 may include a circuit structure electrically connected to the connector 40. Specifically, in some examples, the second housing 20 may include a circuit structure electrically connected to the conductive material within the conductive path of the connector 40. In some examples, one end of the conductive path may contact the connection portion 32, and the other end of the conductive path may contact the circuit structure. Thus, the connection portion 32 of the sensor 30 can be electrically connected to the circuit structure of the second housing 20 via the connector 40.

[0066] In some examples, the connector 40 may include a conductor 41 . In some examples, the conductor 41 may be located within a conductive channel. In some examples, the conductor 41 may have conductive properties. In some examples, the connector 40 may include at least one conductor 41 .

[0067] In some examples, the connector 40 may have a conductor 41 aligned with the electrical contacts. In some examples, the connector 40 may have a conductor 41 aligned with the electrical contacts and the same number as the electrical contacts. For example, when the number of electrical contacts of the connecting portion 32 is 3, the connector 40 may have 3 conductors 41. In some examples, one end of the conductor 41 may be connected to the electrical contact, and the other end of the conductor 41 may be connected to the circuit structure. Specifically, one end of each conductor 41 may be connected to the aligned electrical contact, and the other end of each conductor 41 may be connected to the circuit structure of the second shell 20. In this case, since the sensor 30 generally transmits electrical signals through electrical contacts, by providing the same number of conductors 41 aligned with the electrical contacts, the electrical signal of each electrical contact in the sensor 30 can be transmitted to the circuit structure via the corresponding conductor 41, thereby reducing the current instability and further improving the reliability and stability of the electrical connection between the sensor 30 and the circuit structure.

[0068] In some examples, referring to FIG4B , the connector 40 may include an inner cavity 42 . In some examples, the conductive path may be disposed in the inner cavity 42 . In some examples, the conductor 41 may be disposed in the inner cavity 42 .

[0069] In some examples, the connector 40 may include a connection opening 43 (see FIG. 4B ). The connection opening 43 may be configured to allow the connector 40 to be in an open state or a closed state. In some examples, the sensor 30 may be placed in the inner cavity 42 of the connector 40. In some examples, the connection portion 32 of the sensor 30 may be placed in the connection opening 43 of the connector 40. Specifically, when the connector 40 is in the open state, the connection portion 32 of the sensor 30 may be placed in the inner cavity 42 of the connector 40 through the connection opening 43; when the connector 40 is in the closed state, the connector 40 may completely accommodate the connection portion 32 in the inner cavity 42.

[0070] In some examples, the connection body 40 may include a connection upper portion 44 and a connection lower portion 45 (see FIG. 5A and FIG. 5B ). The connection upper portion 44 and the connection lower portion 45 may be formed based on the connection opening 43 .

[0071] In some examples, referring to FIG5A , the connector 40 may include an inner cavity 42 and at least one pivot portion 46. The pivot portion 46 may be used to control the connector 40 to open or close. That is, the pivot portion 46 may be used to control the connector 40 to be in an open state or a closed state. In some examples, the connector 40 may be configured to receive the conductor 41 into the inner cavity 42 in an open state. In this case, the connector 40 can be controlled to open so as to facilitate operation on the conductor 41 (for example, placement or replacement of the conductor 41, etc.), and at the same time, the connector 40 can be controlled to close so that the conductor 41 can be placed in the inner cavity 42 of the connector 40 more firmly.

[0072] In some examples, the pivot portions 46 may be provided on both sides of the connection opening 43. In other words, the pivot portions 46 may be connected to the upper connection portion 44 and the lower connection portion 45, respectively. In this case, the upper connection portion 44 and the lower connection portion 45 can be controlled to move closer or further away along the pivot portions 46, thereby controlling the connection body 40 to be in an open or closed state.

[0073] In some examples, the connector 40 may include a plurality of pivot portions 46 .

[0074] In some examples, the conductive pathway may be located at the connecting upper portion 44 .

[0075] In some examples, connector 40 can be configured to receive conductor 41 onto connector upper portion 44 in an open position. In some examples, connector upper portion 44 can include a first surface that contacts connector portion 32 of sensor 30 and a second surface that contacts the circuit structure. In this case, one end of conductor 41 can be electrically connected to connector portion 32 of sensor 30 via the first surface, while the other end of conductor 41 can be electrically connected to the circuit structure via the second surface, thereby enabling electrical signals from sensor 30 to be transmitted to the circuit structure.

[0076] In some examples, the lower connecting portion 45 may include a third surface that contacts the connecting portion 32 of the sensor 30. In some examples, when the connector 40 is in a closed state, the first surface and the third surface may be configured to cover and compress the connecting portion 32 of the sensor 30. This can improve the sealing performance between the connector 40 and the connecting portion 32.

[0077] In some examples, the connector 40 can be made of a polymer material. In some examples, the connector 40 can be made of silicone rubber. In this case, due to the elasticity of silicone rubber, it can better wrap around the connecting portion 32 due to elastic deformation, thereby further improving the sealing between the connector 40 and the connecting portion 32.

[0078] In some examples, the connector 40 may include a pair of tab structures 47 (see FIG. 5A ). In some examples, the tab structures 47 may include a first tab 470 and a second tab 471 disposed opposite each other. In some examples, the tab structures 47 may be disposed along both sides of the connection opening 43. In other words, the first tab 470 may be disposed on the upper connection portion 44, and the second tab 471 may be disposed on the lower connection portion 45. In some examples, when the connector 40 is in a closed state, the first tab 470 may abut against the second tab 471.

[0079] In some examples, the connector 40 may include at least one pair of sheet structures 47 disposed opposite each other. The sheet structures 47 may have second through-holes 472. In some examples, the receiving portion 16 may include a column 160 (see FIG. 4B ) extending through the second through-holes 472 to connect with the sheet structures 47. In this case, by connecting the column 160 through the second through-holes 472 and the sheet structures 47, the connector 40 and the receiving portion 16 can be fixedly connected, thereby improving the stability of the connector 40 disposed in the receiving portion 16.

[0080] In some examples, the diameter of the second through hole 472 can match the bottom diameter of the pillar 160. In some examples, “match” can mean that the diameter of the second through hole 472 is not greater than / less than or equal to the bottom diameter of the pillar 160.

[0081] In some examples, the connector 40 may have a flange portion 48 (see FIG5A ). Specifically, the end surface where the connector 40 and the fixing member 50 are joined may have a flange portion 48. In some examples, the flange portion 48 may be elastic. In this case, when the connector 40 and the fixing member 50 are joined, the fixing member 50 squeezes the flange portion 48, causing the flange portion 48 to deform, thereby applying greater pressure to the joined portions, thereby making the joint tighter. In addition, the deformation of the flange portion 48 can fill the gap created during the joint, thereby further improving the tightness of the joint.

[0082] In some examples, the end surface where the connector 40 and the fixing member 50 are joined may be the second surface of the connecting upper portion 44. In other words, the flange portion 48 may be provided on the second surface of the connecting upper portion 44. In some examples, the second surface may be extended toward the circuit structure to form the flange portion 48.

[0083] In some examples, the fixing member 50 may be configured to fix the connecting body 40 and the connecting portion 32 in the receiving portion 16 .

[0084] In some examples, referring to FIG6 , the fixing member 50 may have a hollow structure 51. Specifically, the upper end of the fixing member 50 may have a hollow structure 51. In some examples, the upper end of the fixing member 50 may abut against the connector 40. Specifically, the upper end of the fixing member 50 may abut against the second surface of the connecting upper portion 44. In some examples, the conductor 41 may be at least partially exposed through the hollow structure 51 to be electrically connected to the circuit structure. In this case, the conductor 41 in the connector 40 can be more fully contacted with the circuit structure without affecting the fixing effect of the fixing member 50 on the connector 40.

[0085] In some examples, the conductive material in the conductive channel may also be electrically connected to the circuit structure through the hollow structure 51 .

[0086] In some examples, the fixing member 50 may have a snap-fit ​​groove 52. In some examples, the snap-fit ​​groove 52 may be configured to snap fit the fixing member 50 with the receiving portion 16. In some examples, the fixing member 50 may have at least one snap-fit ​​groove 52.

[0087] In some examples, with continued reference to FIG. 4B , the receiving portion 16 may have at least one snap-fit ​​protrusion 161. For example, the receiving portion 16 may have one, two, or three snap-fit ​​protrusions 161. In some examples, with reference to FIG. 6 , the sidewall of the fixing member 50 may have a snap-fit ​​groove 52 that matches the snap-fit ​​protrusion 161. In some examples, the snap-fit ​​groove 52 may engage with the snap-fit ​​protrusion 161 to securely engage the fixing member 50 with the receiving portion 16. In this case, the fixing member 50 can be more tightly coupled to the receiving portion 16, thereby improving the stability of the connection between the connector 40 and the connecting portion 32 provided in the receiving portion 16.

[0088] In some examples, the snap grooves 52 that match the snap protrusions 161 may mean that the number of the snap grooves 52 is the same as the number of the snap protrusions 161. For example, when the number of the snap protrusions 161 is three, the number of the snap grooves 52 may be three.

[0089] In some examples, as shown in FIG6 , the fixing member 50 may include a first block 53 and a second block 54. In some examples, the first block 53 and the second block 54 may be disposed opposite each other on the inner wall of the fixing member 50. In some examples, the first block 53 and the second block 54 may be configured to abut against the receiving portion 16. This can further improve the stability of the connection between the fixing member 50 and the receiving portion 16.

[0090] In some examples, referring to FIG. 6 , the fixing member 50 may include a notch portion 55 .

[0091] In some examples, the fixing member 50 may include at least one notch portion 55. For example, the fixing member 50 may include 1, 2, or 3 notches 55. In some examples, the notch portion 55 may be located on the side wall of the fixing member 50. In some examples, the notch portion 55 may be located on the edge of the side wall of the fixing member 50. That is, the notch portion 55 may be located at the connection of each surface of the side wall of the fixing member 50. In this case, by providing the notch portion 55, the edge connection of the fixing member 50 (that is, the side wall) can be interrupted, and the side wall of the fixing member 50 can be elastically deformed outward when the fixing member 50 is assembled, thereby facilitating the assembly of the fixing member 50 with the accommodating portion 16.

[0092] In the monitoring device 1 disclosed herein, the connecting portion 32 of the sensor 30 is electrically connected to the circuit structure of the second housing 20 via the connector 40, and the fixing member 50 fixes the connector 40 and the connecting portion 32 to the housing 16 of the first housing 10. In this case, the connector 40 can prevent the electrical contacts of the connecting portion 32 from being exposed (that is, the connecting portion 32 remains sealed), and when the first housing 10 and the second housing 20 become loose or separated, the negative effects caused by the electrical contacts of the connecting portion 32 coming into contact with the external environment (for example, failure or contamination of the connecting portion 32) can be reduced. In addition, the fixing member 50 can stably hold the connecting portion 40 and the connecting portion 32 in the housing 16, reducing the possibility of the connecting portion 40 and the connecting portion 32 becoming loose. At the same time, it can make the connection between the connecting portion 40 and the connecting portion 32 tighter, thereby further reducing the possibility of the electrical contacts being exposed, thereby improving the sealing of the connecting portion 32 of the sensor 30.

[0093] According to the present disclosure, it is possible to provide a monitoring device 1 that improves the sealing performance and stability of the sensor 30 .

[0094] Although the present disclosure has been described in detail above with reference to the accompanying drawings and examples, it will be understood that the above description does not limit the present disclosure in any form. Those skilled in the art may modify and change the present disclosure as needed without departing from the spirit and scope of the present disclosure, and such modifications and variations all fall within the scope of the present disclosure.
