Description

Technical Field

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

[0002] Diabetes is a common chronic disease, which is generally caused by insufficient insulin or poor insulin effect in the body. When the blood glucose level is at a relatively high level for a long time, it may lead to other complications and affect physical health. Therefore, it becomes particularly important to monitor blood glucose concentration in real time. CGM (Continuous Glucose Monitoring) is a continuous blood glucose monitoring technology, which generally includes a sensor assembly and an applicator that is electrically connected to the sensor assembly and attached to the user's body surface. The sensor assembly can be used to obtain analyte information (e.g., glucose concentration) in the user's body and send it to the user's smart device or terminal by the applicator. Thus, the user can timely grasp their own blood glucose level. Among them, the sensor assembly can generally be divided into a sensor part implanted under the user's skin (which can be simply referred to as the implanted part) and a sensor part not implanted under the user's skin (which can be simply referred to as the connection part). The connection part has several sensor electrical contacts, and these electrical contacts are used to electrically connect to the circuit board on the applicator to transmit electrical signals.

[0003] In the prior art, a connecting member is generally configured to keep the connection part stable and have a certain sealing effect. This connecting member can be used to electrically connect the sensor to the circuit board. Usually, the connecting member and the circuit board are arranged on the upper shell of the applicator, and the sensor assembly is arranged at the corresponding position on the lower shell of the applicator. When the upper shell and the lower shell are fitted together, the connecting member can, while pressing the connection part, electrically connect the connection part to the circuit board to transmit electrical signals.

[0004] However, in the above technology, when the upper shell and the lower shell become loose, the connecting member and the connection part may become detached, and at this time, the electrical contacts of the connection part will be exposed. When the exposed electrical contacts are affected by external factors (e.g., exposed to water or a humid environment), it may cause the product to malfunction. In addition, when the contact between the connecting member and the connection part is not tight, it is difficult for the connection part to remain stable, and the sensor may fall off. Summary of the Invention

[0005] The present disclosure is proposed in view of the above-mentioned prior art situation, and its purpose is to provide a monitoring device that can improve the sealing performance and stability of the sensor.

[0006] To this end, the present disclosure provides a monitoring device. The monitoring device is applied to the body surface of a host to monitor the physiological information of the host, and includes a sensor, a connector, a first housing, a fixing member, and a second housing; the sensor includes a connecting portion and an implant portion that can be implanted under the skin of the host, and the connecting portion has electrical contacts; the sensor is electrically connected to the connector through the electrical contacts; the first housing has a receiving portion for receiving the connector and the connecting portion; the fixing member is configured to fix the connector and the connecting portion in the receiving portion; the second housing includes a circuit structure electrically connected to the connector.

[0007] In the monitoring device according to the present disclosure, the connecting portion of the sensor is electrically connected to the circuit structure of the second housing through the connector, and the fixing member fixes the connector and the connecting portion in the receiving portion of the first housing. In this case, the connector can prevent the electrical contacts of the connecting portion from being exposed (that is, keep the connecting portion in a sealed state). When the first housing and the second housing become loose or separated, it can reduce the negative impacts caused by the electrical contacts of the connecting portion contacting the external environment (for example, the connecting portion malfunctions or is contaminated). In addition, the fixing member can stably hold the connector and the connecting portion in the receiving portion, reduce the loosening of the connector and the connecting portion, and at the same time, make the connection between the connector and the connecting portion tighter, thereby further reducing the exposure of the electrical contacts, and further improving the sealing performance of the connecting portion of the sensor.

[0008] In addition, in the monitoring device according to the present disclosure, optionally, the connector has conductors that are aligned with the electrical contacts and have the same number as the electrical contacts. One end of each conductor is connected to the corresponding electrical contact, and the other end of each conductor is connected to the circuit structure. In this case, since the sensor generally transmits electrical signals through electrical contacts, by providing conductors that are aligned with and have the same number as the electrical contacts, the electrical signals of each electrical contact in the sensor can be transmitted to the circuit structure through the corresponding conductor, thereby reducing the instability of the current, and further improving the reliability and stability of the electrical connection between the sensor and the circuit structure.

[0009] In addition, in the monitoring device according to the present disclosure, optionally, the connector includes an inner cavity and at least one pivoting portion. The at least one pivoting portion is used to control the opening or closing of the connector. The connector is configured to receive the conductors into the inner cavity in the open state. In this case, it is possible to control the opening of the connector to facilitate the operation of the conductors (such as placing or replacing the conductors, etc.). At the same time, by controlling the closing of the connector, the conductors can be more firmly placed in the inner cavity of the connector.

[0010] In addition, in the monitoring device according to the present disclosure, optionally, the upper end of the fixing member has a hollow structure, and the conductive body is at least partially exposed through the hollow structure to be electrically connected to the circuit structure. In this case, the conductive body in the connecting body can be more fully in contact with the circuit structure without affecting the fixing effect of the fixing member on the connecting body.

[0011] In addition, in the monitoring device according to the present disclosure, optionally, the accommodating portion has at least one snap projection, and the side wall of the fixing member has a snap groove matching the snap projection. The snap groove and the snap projection are snap-connected to fasten the fixing member and the accommodating portion. In this case, the combination of the fixing member and the accommodating portion can be made closer, thereby improving the stability of the connection between the connecting body and the connecting portion provided in the accommodating portion.

[0012] In addition, in the monitoring device according to the present disclosure, optionally, the first housing has a first through hole, and the implanting portion extends outward 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 implanting portion of the sensor can be placed under the skin of the host.

[0013] In addition, in the monitoring device according to the present disclosure, optionally, the connecting body has at least a pair of sheet structures arranged oppositely, and the sheet structure has a second through hole; the accommodating portion has a column body passing through the second through hole to connect the sheet structures. In this case, by connecting the column body through the second through hole to the sheet structure, the connecting body can be fixedly connected to the accommodating portion, thereby improving the stability of the connecting body provided in the accommodating portion.

[0014] In addition, in the monitoring device according to the present disclosure, optionally, the end face where the connecting body is combined with the fixing member has a flange portion, and the flange portion has elasticity. In this case, when the connecting body is combined with the fixing member, the fixing member will squeeze the flange portion to cause the flange portion to deform. Thereby, a greater pressure can be applied to the combined portion, making the combination closer. In addition, after the flange portion deforms, the gaps generated during combination can be filled, further improving the tightness of the combination.

[0015] In addition, in the monitoring device according to the present disclosure, optionally, the inner contour of the connecting portion and the connecting body matches the inner contour of the accommodating portion; the inner contour of the side wall of the fixing member matches the outer contour of the accommodating portion. In this case, the loosening of the connecting body and the connecting portion in the accommodating portion can be reduced, thereby improving the stability of the connecting body and the connecting portion. In addition, the combination of the fixing member and the accommodating portion can be made closer. At the same time, the assembly error can be reduced, thereby improving the convenience of assembling the fixing member and the accommodating portion.

[0016] In addition, in the monitoring device according to the present disclosure, optionally, the second housing is configured to abut against the fixing member when combined with the first housing. In this case, when the second housing is combined with the first housing, it can exert an effect on the fixing member, so that the fixing member can further press the connecting body, and thus the stability of the connecting body and the connecting portion can be improved. At the same time, since the connection between the connecting body and the connecting portion is tighter, the sealing performance of the connecting portion can be improved.

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

Figure 3B It shows an exploded view of the monitoring device 1 involved in the examples of the present disclosure. Figure 4A It shows a top view of the first housing 10 involved in the examples of the present disclosure. Figure 4B It shows an assembly schematic diagram of the fixing member 50 and the connecting body 40 involved in the examples of the present disclosure.

[0040] In some examples, referring to Figure 3A and Figure 3B , the monitoring device 1 may include a first housing 10. In some examples, referring to Figure 3A and Figure 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 bottom plate 11, and the bottom plate 11 may be applied to the body surface of the host 6. In some examples, the first housing 10 may be used to place the sensor 30. Specifically, in some examples, the bottom plate 11 may be used to place the sensor 30. In some examples, the sensor 30 may include an implanted portion 31 that can be implanted subcutaneously into 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 provided 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 implanted 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 implanted portion 31 of the sensor 30.

[0043] In some examples, the implanted 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 implanted portion 31 of the sensor 30 can be implanted subcutaneously into the host 6.

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

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

[0046] In some examples, the first housing 10 may include a clamping groove 14 (see Figure 3A and Figure 3B ), and the clamping groove 14 may be provided on the first side wall 13. In some examples, the clamping groove 14 may be a square hole, a round hole or an oval hole.

[0047] In some examples, the first housing 10 may include a pressing portion 15 (see Figure 3A and Figure 3B ), and the pressing portion 15 may be provided on the first side wall 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 be coupled or separated from the second housing 20.

[0048] In some examples, the second housing 20 may include a second side wall 21 adapted to the first side wall 13 (see Figure 3B ). Specifically, the first side wall 13 may be coupled to the second side wall 21 wholly or partially to couple the first housing 10 to the second housing 20.

[0049] In some examples, see Figure 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 side wall 21.

[0050] In some examples, the first edge protrusion 22 may be configured to engage with the clamping groove 14. In some examples, the first edge protrusion 22 may be combined with the clamping groove 14 by being inserted into the clamping groove 14. Thus, the first housing 10 and the second housing 20 can be coupled to each other.

[0051] In some examples, the second edge protrusion 23 may be configured to cooperate with the pressing portion 15. In some examples, the pressing portion 15 may include a first end 150 configured to engage with the second edge protrusion 23 (see Figure 3B ). The end face of the first end 150 may fit 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 engagement state between the first end 150 and the second edge protrusion 23. In some examples, the engagement state may include a first state for characterizing the engagement of the second edge protrusion 23 with the first end 150 and a second state for characterizing the looseness of the second edge protrusion 23 from the first end 150.

[0053] In some examples, the engagement state can 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 can be converted into 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, and the electronic module may be configured to process the electrical signal of the sensor 30 for characterizing analyte information. In some examples, the electronic module may be configured to send the analyte information to the smart terminal of the host 6. In this case, it is convenient for the host 6 to obtain its own analyte information, so that its physiological parameters can be monitored in real time.

[0055] In some examples, the circuit structure may include a power module. The power module may be configured to supply electrical energy 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 may be configured to abut against the fixing member 50 when combined with the first housing 10. In this case, when the second housing 20 is combined with the first housing 10, it can exert an action on the fixing member 50, so that the fixing member 50 can further press the connecting body 40, thereby improving the stability of the connecting body 40 and the connecting portion 32. At the same time, since the connection between the connecting body 40 and the connecting portion 32 is tighter, the sealing performance of the connecting portion 32 can be improved.

[0057] In some examples, referring to Figure 4A and Figure 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] In some examples, referring to Figure 4B , the sensor 30 may include a connecting portion 32. The connecting portion 32 may be connected to the implanting portion 31.

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

[0060] In some examples, the sensor 30 may be electrically connected to the connector 40 through electrical contacts. In other words, in some examples, the electrical signals collected by the sensor 30 for characterizing analyte information may be transmitted to the circuit structure through the connector 40.

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

[0062] In some examples, both the connecting portion 32 and the connector 40 may match the inner contour of the receiving portion 16. In some examples, "matching" may mean that the outer perimeters of the connecting portion 32 and the connector 40 may fit snugly against the inner contour of the receiving portion 16. In this case, the looseness of the connector 40 and the connecting portion 32 within the receiving portion 16 can be reduced, thereby improving the stability of the connector 40 and the connecting portion 32.

[0063] In some examples, the inner contour of the side wall of the fixing member 50 may match the outer contour of the receiving portion 16. In this case, the combination of the fixing member 50 and the receiving portion 16 can be made tighter, and at the same time, the assembly error 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 within the conductive channel. In other words, the conductive channel may be filled with the conductive material.

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

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

[0067] In some examples, the connector 40 may have a conductor 41 aligned with the electrical contact. In some examples, the connector 40 may have conductors 41 aligned with the electrical contacts and having the same number as the electrical contacts. For example, when the number of electrical contacts of the connection 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 housing 20. In this case, since the sensor 30 generally transmits electrical signals through the electrical contacts, by providing conductors 41 aligned with and having the same number as the electrical contacts, the electrical signals of each electrical contact in the sensor 30 can be transmitted to the circuit structure via the corresponding conductors 41, thereby reducing the situation of unstable current 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 Figure 4B , the connector 40 may include a lumen 42. In some examples, a conductive channel may be provided in the lumen 42. In some examples, the conductor 41 may be provided in the lumen 42.

[0069] In some examples, the connector 40 may include a connection opening 43 (referring to Figure 4B ). The connection opening 43 may be configured to keep the connector 40 in an open state or a closed state. In some examples, the sensor 30 may be placed in the lumen 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 lumen 42 of the connector 40 through the connection opening 43; when the connector 40 is in the closed state, the connector 40 may completely receive the connection portion 32 in the lumen 42.

[0070] In some examples, the connector 40 may include an upper connection part 44 and a lower connection part 45 (referring to Figure 5A and Figure 5B ). The upper connection part 44 and the lower connection part 45 may be formed based on the connection opening 43.

[0071] In some examples, referring to Figure 5A, the connector 40 may include a lumen 42 and at least one pivot portion 46. The pivot portion 46 may be used to control the opening or closing of the connector 40. 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 lumen 42 in the open state. In this case, the connector 40 can be controlled to open to facilitate the operation of the conductor 41 (such as placing or replacing the conductor 41, etc.). At the same time, by controlling the connector 40 to close, the conductor 41 can be more firmly placed in the lumen 42 of the connector 40.

[0072] In some examples, the pivot portion 46 may be disposed on both sides of the connection opening 43. In other words, the pivot portion 46 may be respectively connected to the upper connection portion 44 and the lower connection portion 45. In this case, the upper connection portion 44 and the lower connection portion 45 can be controlled to approach or separate along the pivot portion 46, so that the connector 40 can be controlled to be in an open state or a closed state.

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

[0074] In some examples, the conductive channel may be located in the upper connection portion 44.

[0075] In some examples, the connector 40 may be configured to receive the conductor 41 into the upper connection portion 44 in the open state. In some examples, the upper connection portion 44 may include a first surface that contacts the connection portion 32 of the sensor 30 and a second surface that contacts the circuit structure. In this case, one end of the conductor 41 can be electrically connected to the connection portion 32 of the sensor 30 based on the first surface, and at the same time, the other end of the conductor 41 can be electrically connected to the circuit structure based on the second surface, thereby enabling the electrical signal of the sensor 30 to be transmitted to the circuit structure.

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

[0077] In some examples, the connector 40 may be made of a polymer material. In some examples, the connector 40 may be made of silicone rubber. In this case, since silicone rubber has elasticity, it can better wrap the connection portion 32 based on elastic deformation, thereby further improving the sealing performance between the connector 40 and the connection portion 32.

[0078] In some examples, the connector 40 may include a pair of sheet structures 47 (see Figure 5A)。In some examples, the sheet structure 47 may include a first sheet 470 and a second sheet 471 which are oppositely arranged. In some examples, the sheet structure 47 may be arranged along both sides of the connection opening 43. In other words, the first sheet 470 may be arranged on the connection upper part 44, and the second sheet 471 may be arranged on the connection lower part 45. In some examples, when the connector 40 is in a closed state, the first sheet 470 may abut against the second sheet 471.

[0079] In some examples, the connector 40 may have at least a pair of sheet structures 47 which are oppositely arranged. The sheet structure 47 may have a second through hole 472. In some examples, the accommodating part 16 may have a cylinder 160 passing through the second through hole 472 to connect the sheet structure 47 (see Figure 4B ). In this case, by connecting the cylinder 160 with the sheet structure 47 through the second through hole 472, the connector 40 can be fixedly connected with the accommodating part 16, so that the stability of the connector 40 arranged in the accommodating part 16 can be improved.

[0080] In some examples, the diameter of the second through hole 472 may match the bottom surface diameter of the cylinder 160. In some examples, "match" may mean that the diameter of the second through hole 472 is not greater than / less than or equal to the bottom surface diameter of the cylinder 160.

[0081] In some examples, the connector 40 may have a flange part 48 (see Figure 5A ). Specifically, the end face of the connector 40 combined with the fixing part 50 may have a flange part 48. In some examples, the flange part 48 may have elasticity. In this case, when the connector 40 is combined with the fixing part 50, the fixing part 50 will extrude the flange part 48 to cause the flange part 48 to deform, thereby being able to apply a greater pressure to the combined part, so that the combination is tighter. In addition, after the flange part 48 deforms, it can fill the gap generated during combination, thereby being able to further improve the tightness of the combination.

[0082] In some examples, the end face of the connector 40 combined with the fixing part 50 may refer to the second face of the connection upper part 44. That is to say, the flange part 48 may be arranged on the second face of the connection upper part 44. In some examples, the second face may be extended towards the direction close to the circuit structure to form the flange part 48.

[0083] In some examples, the fixing part 50 may be configured to fix the connector 40 and the connection part 32 in the accommodating part 16.

[0084] In some examples, see Figure 6, 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 connecting body 40. Specifically, the upper end of the fixing member 50 may abut against the second surface of the upper connecting 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 connecting body 40 can be more fully in contact with the circuit structure without affecting the fixing effect of the fixing member 50 on the connecting body 40.

[0085] In some examples, the conductive material in the conductive channel can 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 groove 52. In some examples, the snap groove 52 can be configured to snap the fixing member 50 with the receiving portion 16. In some examples, the fixing member 50 may have at least one snap groove 52.

[0087] In some examples, continue to refer to Figure 4B , the receiving portion 16 may have at least one snap projection 161. For example, the receiving portion 16 may have 1, 2 or 3 snap projections 161. In some examples, refer to Figure 6 , the side wall of the fixing member 50 may have a snap groove 52 that matches the snap projection 161. In some examples, the snap groove 52 can be snapped with the snap projection 161 to snap the fixing member 50 and the receiving portion 16 together. In this case, the combination of the fixing member 50 and the receiving portion 16 can be made closer, thereby improving the stability of the connection between the connecting body 40 disposed in the receiving portion 16 and the connecting portion 32.

[0088] In some examples, the snap groove 52 that matches the snap projection 161 may mean that the number of snap grooves 52 is the same as the number of snap projections 161. For example, when the number of snap projections 161 is 3, the number of snap grooves 52 can be 3.

[0089] In some examples, refer to Figure 6 , 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 relatively disposed on the inner wall of the fixing member 50. In some examples, the first block 53 and the second block 54 can be configured to abut against the receiving portion 16. Thus, the stability of the connection between the fixing member 50 and the receiving portion 16 can be further improved.

[0090] In some examples, refer to Figure 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 notch portions 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 portion 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 peripheral connection (i.e., the side wall) of the fixing member 50 can be interrupted, and the side wall of the fixing member 50 can be elastically deformed outward when the fixing member 50 is assembled, which is beneficial to the assembly of the fixing member 50 and the receiving portion 16.

[0092] In the monitoring device 1 according to the present disclosure, the connection portion 32 of the sensor 30 is electrically connected to the circuit structure of the second housing 20 through the connection body 40, and the fixing member 50 fixes the connection body 40 and the connection portion 32 in the receiving portion 16 of the first housing 10. In this case, the connection body 40 can prevent the electrical contacts of the connection portion 32 from being exposed (i.e., keep the connection portion 32 in a sealed state). When the first housing 10 and the second housing 20 become loose or separated, it can reduce the negative effects (e.g., the connection portion 32 malfunctions or is contaminated) caused by the electrical contacts of the connection portion 32 coming into contact with the external environment. In addition, the fixing member 50 can stably hold the connection body 40 and the connection portion 32 in the receiving portion 16, reduce the loosening of the connection body 40 and the connection portion 32, and at the same time, make the connection between the connection body 40 and the connection portion 32 tighter, thereby further reducing the exposure of the electrical contacts and improving the sealing performance of the connection portion 32 of the sensor 30.

[0093] According to the present disclosure, a monitoring device 1 that can improve the sealing performance and stability of the sensor 30 can be provided.

[0094] Although the present disclosure has been specifically described above in conjunction with the drawings and examples, it can be understood that the above description does not limit the present disclosure in any form. Those skilled in the art can make deformations and changes to the present disclosure as needed without departing from the essence and scope of the present disclosure, and these deformations and changes all fall within the scope of the present disclosure.
