Description

Analytical monitoring device

[0001] The present invention relates to a device for inserting into a body to monitor analytes.

[0002] Continuous Glucose Monitoring (CGM) devices are systems that continuously measure blood sugar levels by inserting tiny sensors into the skin of diabetic patients. These devices consist of a sensor and an electronic device, which processes and records the analyte (blood sugar) measured by the sensor, providing patients with real-time blood sugar information. CGM devices are typically attached to the skin and can continuously monitor blood sugar levels for 7 to 15 days, allowing patients to manage their blood sugar levels more precisely.

[0003] However, conventional continuous glucose monitoring devices have technical limitations. Specifically, designing miniaturized devices presents technical challenges in stably securing the sensor and accurately connecting the sensor to the circuit. These technical challenges can reduce the device's performance and reliability, negatively impacting its commercialization and patient convenience.

[0004] Therefore, there is a need to develop a technology that can improve the connectivity between sensors and circuits and stably fix the sensors in miniaturized devices for monitoring analytes (blood sugar).

[0005] The purpose of the present invention is to improve the connectivity of a sensor and a circuit in a miniaturized device for monitoring analytes and to stably fix the sensor.

The coupling retaining portion (500) may maintain the coupling state of the contact retaining portion (400), thereby strengthening the contact state between the sensor portion (200) and the contact portion (320).

[0103]

[0104] Hereinafter, with reference to FIGS. 4 to 13, an analysis monitoring device according to one embodiment of the present invention will be described.

[0105] Figure 4 is a perspective view of a circuit unit (300) according to one embodiment of the present invention.

[0106] Referring to Fig. 4, the circuit portion (300) may include a body portion (310) and a contact portion (320). In Fig. 4, the circuit portion (300) is illustrated as a circle, but is not limited thereto and may be formed in various shapes.

[0107] The body portion (310) may include various configurations. Specifically, the body portion (310) may include a battery receiving groove (316) in which at least a portion of the battery (350) is received. In addition, the body portion (310) may include a fixing portion coupling groove (317) to which the fixing portion (250) is coupled.

[0108] A groove (315) for accommodating a sensor portion (200) may be formed in the body portion (310). The connection portion (210) of the sensor portion (200) may be accommodated in the groove portion (315), so that the connection portion (210) may come into contact with the contact portion (320).

[0109] The contact portion (320) may extend horizontally from the groove portion (315) of the body portion (310). The contact portions (320) may be formed in the same number as the number of sensor terminals (230) of the sensor portion (200). Referring to Fig. 4, three contact portions (320) are formed spaced apart from each other.

[0110] As illustrated in FIG. 4, the plurality of contact portions (320) may extend from one side of the groove portion (315) of the body portion (310). However, in some cases, the plurality of contact portions (320) may extend from opposite sides of the groove portion (315).

[0111] The contact portion (320) may be formed of a flexible material. Therefore, the shape of the contact portion (320) may be changed by contact with the connecting portion (210). Fig. 4 illustrates the shape of the contact portion (320) before it comes into contact with the connecting portion (210). The contact portion (320) may extend horizontally in a portion adjacent to the body portion (310) before coming into contact with the connecting portion (210). In some cases, the contact portion (320) may bend downward due to its own weight before coming into contact with the connecting portion (210), but may generally remain extended horizontally.

[0112]

[0113] Fig. 5 is a cross-sectional view schematically illustrating the laminated structure of the circuit portion (300) illustrated in Fig. 4 taken along line AA'. Referring to Fig. 5, the configuration of the circuit portion (300) formed as a rigid flexible PCB will be described in detail. Fig. 5 is an exemplary drawing for explaining the configuration of the circuit portion (300). The laminated form of the wiring layer and resin layer of the circuit portion (300) is not limited to that illustrated in Fig. 5.

[0114] The body portion (310) corresponds to the rigid portion of the Rigid Flexible PCB. The body portion (310) is formed in a form in which multiple layers are laminated. Specifically, the body portion (310) may be formed by laminating wiring layers (3002, 3004, 3007), resin layers (3003, 3005, 3006), and solder resist layers (3001, 3008). Since the body portion (310) is formed by laminating rigid wiring layers (3002, 3007) and rigid resin layers (3003, 3006), the body portion (310) can be formed as a rigid substrate as a whole.

[0115] The contact portion (320) may correspond to a flexible portion of a rigid flexible PCB. The contact portion (320) may extend from a portion of the body portion (310). The contact portion (320) may extend from a portion of a plurality of laminated layers constituting the body portion (310).

[0116] Specifically, the contact portion (320) may be an extension of the intermediate wiring layer (3004) and the resin layer (3005) of the body portion (310). Here, the intermediate wiring layer (3004) may be formed relatively thinner than the other wiring layers (3003, 3006) and thus may have a flexible characteristic. In addition, the resin layer (3005), unlike the other resin layers (3003, 3006), may be formed of a flexible resin material (such as polyimide) and thus may have a flexible characteristic. Therefore, the contact portion (320) may be formed as a flexible substrate as a whole.

[0117] Although not shown in the drawing, in some cases, a non-conductive coverlay layer (not shown) or the like may be added to the surface of the wiring layer (3004) of the contact portion (320).

[0121] The protrusion (411) may be formed in a shape that protrudes upward from the lower surface (122). Specifically, the protrusion (411) may be formed in the shape of a wall that protrudes upward from the lower surface (122). The connecting portion (210) of the sensor unit (200) may be in contact with one surface of the protrusion (411). One surface of the connecting portion (210) may be supported by being in contact with the protrusion (411).

[0122] The separation portion (412) may be formed in a shape that protrudes upward from the lower surface (122). The separation portion (412) may be positioned at a position spaced apart from the protrusion (411).

The connecting portion (210) of the sensor portion (200) is coupled between the protrusion (411) and the separation portion (412).

[0123] The separation portion (412) may be formed in a plurality of numbers. Referring to FIG. 6, four separation portions (412) are positioned at a predetermined interval from each other. A contact portion (320) may pass between adjacent separation portions (412).

[0124] The sensor unit (200) may include a connection unit (210) and a sensing unit (220).

[0125] The connecting portion (210) may be positioned in the internal space of the housing (100). Specifically, the connecting portion (210) may be formed in a plate shape that is vertically erected in the internal space of the housing (100). The connecting portion (210) may include at least one sensor terminal (230). Referring to FIG. 6, three sensor terminals (230) are formed on one surface of the connecting portion (210).

[0126] The sensing portion (220) extends from the connecting portion (210). The sensing portion (220) may extend downwardly from the end of the connecting portion (210). Accordingly, the sensing portion (220) may extend toward the user's skin.

[0127]

[0128] Fig. 7 is a perspective view of the lower housing (120) and sensor unit (200) combined in the state of Fig. 6.

[0129] As illustrated in FIG. 7, the sensor unit (200) may be coupled to the lower housing (120) before the circuit unit (300). When the sensor unit (200) is coupled to the lower housing (120), the connecting unit (210) may be fitted between the protrusion (411) and the spacer (412) so that the plate-shaped connecting unit (210) may be vertically erected. In addition, the sensor terminal (230) may be exposed laterally through the space between the plurality of spacers (412). When the sensor unit (200) is coupled to the lower housing (120), the sensing unit (220) may penetrate the lower opening (121) so that at least a portion thereof may be exposed to the outside of the housing (100).

[0130]

[0131] Fig. 8 is a perspective view of a state in which a circuit unit (300) is additionally connected to the lower housing (120) and the sensor unit (200) in the state of Fig. 7.

[0132] Referring to Fig. 8, the circuit unit (300) can be additionally coupled after the lower housing (120) and the sensor unit (200) are coupled. The circuit unit (300) can be coupled by descending from the upper portion of the lower housing (120) while the lower housing (120) and the sensor unit (200) are coupled. Accordingly, the sensor unit (200) and the protrusion (411) are positioned between the groove (315) of the circuit unit (300). In addition, a plurality of contact portions (320) can pass between a plurality of separation portions (412).

[0133] As the circuit part (300) is coupled, the contact part (320) comes into contact with the connection part (210). Specifically, the contact terminal (321) formed on the surface of the contact part (320) comes into contact with the sensor terminal. As the contact part (320) comes into contact with the connection part (210), the shape of the contact part (320) may be deformed according to the contact. Specifically, the contact part (320) may be deformed to bend upward.

[0134] Although not shown in the drawing, contrary to what was described above, there may be a case where the circuit portion (300) is coupled to the lower housing (120) before the sensor portion (200), and then the sensor portion (200) is additionally coupled thereafter. In this case, as the contact portion (320) comes into contact with the connecting portion, the contact portion (320) may be deformed to bend downward.

[0135]

[0136] Fig. 9 is a cross-sectional view of the lower housing (120), sensor unit (200), and circuit unit (300) shown in Fig. 8 taken along line AA'.

[0137] The connecting portion (210) of the sensor portion (200) is fitted between the protrusion (411) and the separation portion (412) so that the plate-shaped connecting portion (210) can be erected in a vertical direction. A sensor terminal can be formed on one surface of the connecting portion (210). The other surface of the connecting portion (210) can be supported by contacting the protrusion (411).

[0138] The contact portion (320) may include a horizontal extension portion (322), a bending portion (323), and a contact extension portion (324). The horizontal extension portion (322) may be a portion adjacent to the body portion (310) and extending in a horizontal direction. The bending portion (323) may extend from an end of the horizontal extension portion (322) and may bend upward or downward by contact with the connecting portion (210). The contact extension portion (324) may extend from an end of the bending portion (323) and may extend in parallel by contacting the connecting portion (210).

[0139] The contact portion (320) may include a contact terminal (321). The contact terminal (321) may be formed on the lower surface of the contact extension portion (324). The contact terminal (321) may be brought into contact with the corresponding sensor terminal (230).

[0140] The contact portion (320) may be formed of a material that is flexible and has a predetermined restoring force. Accordingly, although the contact portion (320) is in an upwardly bent state, it may have a property of recovering in a horizontal direction. Depending on this restoring force, the contact terminal (321) may be brought into close contact with the sensor terminal (230) and maintain a contact state.

[0141]

[0142] Fig. 10 is a perspective view of a state in which a contact maintenance part (400) is additionally connected to the state in Fig. 8. Fig. 11 is a cross-sectional view of the lower housing (120), sensor part (200), circuit part (300), and contact maintenance part (400) shown in Fig. 10 taken along line AA'.

[0143] Referring to FIGS. 10 and 11, a contact maintenance portion (400) may be additionally coupled to maintain the contact state between the contact portion (320) and the connection portion (210).

[0144] The contact maintenance portion (400) may include an extension portion (410) and a coupling portion (420). The extension portion (410) is configured to extend from the lower housing (120) and is described above with reference to FIG. 6. The extension portion (410) may include a protrusion portion (411) and a separation portion (412).

[0145] The coupling portion (420) is configured to be coupled with the extension portion (410). The coupling portion (420) is formed as a separate configuration from the housing (100), and can be additionally coupled after the sensor portion (200) and the circuit portion (300) are coupled to the lower housing (120). As an example, the contact maintenance portion (400) can be formed as a protrusion (411), a separation portion (412), and a fitting clip coupled from above between the protrusion (411) and the separation portion (412).

[0146] Specifically, the coupling portion (420) may include an insertion portion (421) that is inserted and coupled between the protrusion portion (411) and the separation portion (412). When the insertion portion (421) is inserted between the protrusion portion (411) and the separation portion (412), the contact portion (320) and the connection portion (210) are positioned between the insertion portion (421) and the protrusion portion (411). The contact portion (320) and the connection portion (210) may be maintained in close contact with each other between the insertion portion (421) and the protrusion portion (411).

[0147] The insertion portion (421) can be fitted between the protrusion portion (411) and the separation portion (412) in a force-fit manner. Specifically, the thickness of the insertion portion (421) is formed to be greater than the space between the contact portion (320) and the separation portion (412), so that the space between the protrusion portion (411) and the separation portion (412) is widened by the force-fit of the insertion portion (421), and the insertion portion (421) can be fitted. In this case, due to the restoring force of the protrusion portion (411) and the separation portion (412), the insertion portion (421) can press the contact portion (320) in a horizontal direction toward the connection portion (210). Accordingly, the press-fit state between the contact portion (320) and the connection portion (210) can be maintained more strongly.

[0148] The separation portion (412) may include an inclined portion (413) formed in a direction facing the protrusion (411). When the coupling portion (420) is coupled to the separation portion (412), the coupling portion (420) may be coupled while descending along the inclined portion (413).

[0149] Due to the angle of the inclined portion (413), a self-locking effect can be generated at the coupling portion (420) that prevents the coupling from being loosened by an external force. Through this, the degree of adhesion between the connection portion (210) and the contact portion (320) can be improved. When the contact portion (320) includes a plurality of spaced apart contact portions (320), the spaced portion (412) can be positioned between the plurality of contact portions (320).

[0150] In FIG. 10 and FIG. 11, the connecting portion (210) is shown in contact with the protrusion (411), and the contact portion (320) is shown in contact with the joining portion (420), so that they are in close contact with each other. However, conversely, it is also possible for the contact portion (320) to be in contact with the protrusion (411), and the connecting portion (210) to be in contact with the joining portion (420), so that they are in close contact with each other.

[0151]

[0152] Fig. 12 is a perspective view of a state in which a joint maintenance part (500) is additionally connected to the state of Fig. 10. Fig. 13 is a cross-sectional view of the lower housing (120), sensor part (200), circuit part (300), contact maintenance part (400), and joint maintenance part (500) shown in Fig. 12 taken along line AA'.

[0153] Referring to FIGS. 12 and 13, in order to maintain the engagement state of the engagement retaining member (500), an additional engagement retaining member (500) may be engaged.

[0154] The coupling retaining member (500) can maintain the coupling state of the extension member (410) and the coupling member (420). Specifically, the coupling retaining member (500) is located between the upper housing (110) and the contact retaining member (400), and can prevent the coupling member (420) from moving upward and separating from the extension member (410).

[0155] The joint retaining member (500) may include a flexible member positioned between the lower surface of the upper housing (110) and the contact retaining member (400). The flexible member may be, for example, a cushion tape, a foam tape, or a poron member.

[0156] The coupling retaining portion (500) may be positioned on the upper surface of the coupling portion (420). Specifically, the coupling retaining portion (500) may be positioned in the space between the upper housing (110) and the coupling portion (420). When the upper housing (110) is coupled to the lower housing (120), the coupling retaining portion (500) may be compressed between the upper housing (110) and the coupling portion (420). Accordingly, the coupling retaining portion (500) may press the coupling portion (420) in the direction of the extension portion (410).

[0157] The coupling retaining member (500) may be attached to the lower side of the upper surface of the upper housing (110). When the coupling retaining member (500) is attached to the upper housing (110), the coupling retaining member (500) may be positioned in the space between the upper housing (110) and the coupling member (420) as it is coupled to the lower housing (120). To this end, a location where the coupling retaining member (500) is to be attached may be specified on the lower side of the upper surface of the upper housing (110).

[0158]

[0159] Hereinafter, with reference to FIGS. 14 to 16, an analysis monitoring device according to another embodiment of the present invention will be described.

[0160] FIG. 14 is a perspective view of a lower housing (120), a sensor unit (200), and a circuit unit (300-1) combined according to another embodiment of the present invention.

[0161] The circuit portion (300-1) may be formed in the form of a combination of a rigid circuit board and a flexible circuit board. Specifically, the body portion (310-1) may be formed of a rigid circuit board, and the contact portion (320-1) may be formed of a flexible circuit board (Flexible PCB) coupled to the body portion (310-1).

[0162] The contact portion (320-1) can be coupled to the upper surface of the body portion (310-1). The contact portion (320-1) is coupled to be electrically connected to the body portion (310-1), so that measurement data of the sensor portion (200) can be transmitted to the body portion (310-1) through the contact portion (320-1).

[0163]

[0164] Fig. 15 is a perspective view of a state in which a contact maintenance part (400-1) is additionally attached to the state in Fig. 14. Fig. 16 is a cross-sectional view of the lower housing (120), sensor part (200), circuit part (300-1), and contact maintenance part (400-1) shown in Fig. 15 taken along line AA'.

[0165] Referring to FIGS. 15 and 16, a contact maintenance portion (400-1) may be additionally coupled to maintain the contact state between the contact portion (320-1) and the connection portion (210).

[0166] The contact maintenance portion (400-1) may include an extension portion (410-1) and a coupling portion (420-1).

[0167] The extension (410-1) may include a protrusion (411-1), a rotation axis (414), and a fixed pin (415).

[0168] The protrusion (411-1) may be formed in the form of a wall protruding upward from the lower surface (122). The connecting portion (210) of the sensor unit (200) may be in contact with one surface of the protrusion (411-1). One surface of the connecting portion (210) may be supported by being in contact with the protrusion (411-1).

[0169] The rotation axis (414) may be formed in the shape of a column protruding upward from the lower surface (122). The rotation axis (414) may be located at a position spaced apart from the protrusion (411).

[0170] The coupling member (420-1) may be a rotating member that can rotate around a rotation axis (414). The coupling member (420-1) may include an insertion hole into which the rotation axis (414) is inserted. The coupling member (420-1) may rotate and move to be adjacent to the protrusion (411-1).

[0171] The fixed pin (415) can fix the connecting portion (420-1) adjacent to the protrusion (411). Specifically, the connecting portion (420-1) can be rotated adjacent to the protrusion (411-1) and fitted into the fixed pin (415). The connecting portion can be prevented from rotating away from the protrusion (411-1) by the fixed pin (415).

[0172] When the connecting portion (420-1) and the protrusion (411-1) are fixed in an adjacent state, the contact portion (320-1) and the connecting portion (210) can be maintained in a state of close contact with each other between the connecting portion (420-1) and the protrusion (411-1). As the connecting portion (420-1) is fixed by the fixing pin (415), the connecting portion (420-1) can close the contact portion (320-1) in a horizontal direction toward the connecting portion (210). Accordingly, the close contact state between the contact portion (320-1) and the connecting portion (210) can be maintained more strongly.

[0173] Referring to Fig. 16, the connecting portion (420-1) may be in contact with the contact portion (320-1), thereby bringing the connecting portion (210) and the contact portion (320-1) into close contact with each other. In some cases, the connecting portion (420-1) may be formed in a shape in which at least a portion thereof is extended toward the contact portion (320-1), as illustrated in Fig. 16. However, the connecting portion (420-1) is not limited to the shape illustrated in Fig. 16 and may be implemented in various shapes.

[0174] The coupling retaining member (500) may be located in the internal space of the housing (100-1). The coupling retaining member (500) may be attached to the lower side of the upper surface of the upper housing (110-1). When the coupling retaining member (500) is attached to the upper housing (110-1), the coupling retaining member (500-1) may be positioned in the space between the upper housing (110-1) and the coupling member (420-1) as it is coupled to the lower housing (120-1). To this end, a location where the coupling retaining member (500-1) is to be attached may be specified on the lower side of the upper surface of the upper housing (110-1).

[0175] Hereinafter, with reference to FIGS. 17 to 22, an analysis monitoring device according to another embodiment of the present invention will be described.

[0176] Fig. 17 is a drawing showing both sides of a sensor unit (200) according to another embodiment of the present invention. Fig. 18 is a perspective view showing a state in which a lower housing (120), a sensor unit (200), and a circuit unit (300-2) are combined according to another embodiment of the present invention. Fig. 19 is a cross-sectional view taken along line AA' of Fig. 18.

[0177] Referring to Fig. 17, the sensor terminal (230) may be formed on the first surface (211a) or the second surface (211b) of the connecting portion (210). Here, the first surface (211a) and the second surface (211b) may be opposite surfaces of the connecting portion (210). As illustrated in Fig. 17, two first sensor terminals (230a) may be formed on the first surface (211a) of the connecting portion (210), and one second sensor terminal (230b) may be formed on the second surface (211b) opposite to the first surface (211a). The number of the first sensor terminals (230a) and the second sensor terminals (230b) may vary.

[0178] The first sensor terminal (230a) and the second sensor terminal (230b) may be formed in different parts of the sensor unit (200). Specifically, the first sensor terminal (230a) may be formed on the first surface (211a) of the first part of the connection unit (210), and the second sensor terminal (230b) may be formed on the second surface (211b) of the second part of the connection unit (210). Here, the first and second parts of the connection unit (210) may not face each other. Accordingly, the first sensor terminal (230a) and the second sensor terminal (230b) may be positioned so as not to face each other in the connection unit (210).

[0179] Referring to Fig. 18, the circuit portion (300-2) may be formed as a flexible circuit board. Specifically, the body portion (310-2) and the contact portion (320-2) may be formed as one flexible circuit board.

[0180] The contact portion (320-2) may be formed to correspond to the sensor terminal (230) of the sensor portion (200) described above. Specifically, the contact portion (320-2) may include a first contact portion (320-2a) and a second contact portion (320-2b). The first contact portion (320-2a) may extend from the first end (312a) of the body portion (310-2) toward the first surface (211a) and may come into contact with the first sensor terminal (230a). The second contact portion (320-2b) may extend from the second end (312b) of the body portion (310-2) toward the second surface (211b) and may come into contact with the second sensor terminal (230b).

[0181] Referring to FIGS. 18 and 19, the extension (410-2) may include a protrusion protruding from the lower housing (120). The protrusion may include a first protrusion (411-2a) and a second protrusion (411-2b) spaced apart from each other.

[0182] The first protrusion (411-2a) can be in contact with the second surface (211b) of the first portion of the connecting portion (210). A first sensor terminal (230a) can be formed on the first surface (211a) of the first portion of the connecting portion (210). Accordingly, the first protrusion (411a) can support the opposite surface of the first sensor terminal (230a).

[0183] The second protrusion (411-2b) can be in contact with the first surface (211a) of the second portion of the connecting portion (210). A second sensor terminal (230b) can be formed on the second surface (211b) of the second portion of the connecting portion (210). Accordingly, the second protrusion (411-2b) can support the opposite surface of the second sensor terminal (230b).

[0184] As illustrated in Fig. 18, a plurality of first protrusions (411-2a) and second protrusions (411-2b) may be formed. Accordingly, when the sensor unit (200) is coupled to the lower housing (120), the second sensor terminal (230b) may be exposed between the plurality of first protrusions (411-2a), and the first sensor terminal (230a) may be exposed between the plurality of second protrusions (411-2b). Thereafter, when the circuit part (300-2) is coupled to the lower housing (120), the first contact part (320-2a) can come into contact with the first sensor terminal (230a) while passing between the plurality of second protrusions (411-2b), and the second contact part (320-2b) can come into contact with the second sensor terminal (230b) while passing between the plurality of first protrusions (411-2a).

[0185] The circuit portion (300-2) may be a flexible circuit board in which the body portion (310-2) and the contact portion (320-2) are formed integrally. In this case, the contact portion (320-2) may protrude and extend horizontally from a portion of the body portion (310-2).

[0186] Specifically, when the circuit portion (300-2) is a flexible circuit board formed integrally, the thicknesses of the body portion (310-2) and the contact portion (320-2) may be the same. That is, unlike in FIG. 11, where the contact portion (320) is formed by extending between the body portion (310) (formed thin), in FIG. 19, the contact portion (320-2) may be formed integrally with the body portion (310-2) (formed with the same thickness as the body portion).

[0187]

[0188] Referring to FIG. 20, the contact maintenance portion (400-2) includes a protrusion (410-2) and a coupling portion (420-2). The coupling portion (420-2) may include a first coupling portion (420-2a) and a second coupling portion (420-2b).

[0189] The first connecting portion (420-2a) can be connected to the second protrusion (411-2b). Specifically, the first connecting portion (420-2a) can be connected to the second protrusion (411-2b) in the direction of the first surface (211a). When the first connecting portion (420-2a) is connected to the second protrusion (411-2b), the first contact portion (320-2a) and the first sensor terminal (230a) can be brought into close contact.

[0190] As illustrated in Fig. 20, one first connecting portion (420-2a) can be connected to a plurality of second protrusions (411-2b). To this end, the first connecting portion (420-2a) can be formed with connecting grooves corresponding to the number of second protrusions (411-2b).

[0191] The second connecting portion (420-2b) can be connected to the first protrusion (411-2a). Specifically, the second connecting portion (420-2b) can be connected to the first protrusion (411-2a) in the direction of the second surface (211b). The second connecting portion (420-2b) can be connected to the first protrusion (411-2a) and bring the second contact portion (320-2b) and the second sensor terminal (230b) into close contact.

[0192] As illustrated in Fig. 20, one second connecting portion (420-2b) can be connected to a plurality of first protrusions (411-2a). To this end, the second connecting portion (420-2b) can be formed with connecting grooves corresponding to the number of first protrusions (411-2a).

[0193] An inclined surface (422) that is coupled with a coupling retaining portion (500-2) may be formed on the upper portion of the coupling portion (420-2). The coupling of the inclined surface (422) with the coupling retaining portion (500-2) will be described with reference to FIGS. 21 and 22 below.

[0194]

[0195] FIG. 21 is a perspective view of the lower surface of the upper housing (110-2) according to one embodiment of the present invention, and FIG. 22 is a cross-sectional view of the state in which the lower housing (120-2), the circuit portion (300-2), the contact holding portion (400-2), the coupling holding portion (500-2), and the upper housing (110-2) are coupled according to one embodiment of the present invention.

[0196] Referring to FIG. 21, the housing (100-2) may include a coupling retaining portion (500-2). As an example, the coupling retaining portion (500-2) may include an upper protrusion (520) that protrudes from the lower surface of the upper housing (110-2) and comes into contact with the coupling portion (420-2). Specifically, the upper protrusion (520) may be formed in a form that protrudes from the lower surface of the upper housing (110-2) and comes into contact with the coupling portion (420-2).

[0197] The upper protrusion (520) may include an opposing inclined surface (521). In FIG. 19, the engaging portion (420-2) of the contact maintaining portion (400-2) may include an inclined surface (422). The opposing inclined surfaces (521) may be formed in a corresponding number at a position opposite to the inclined surface (422) of the engaging portion (420-2). The opposing inclined surfaces (521) may contact the inclined surface (422) to improve the engagement maintaining state of the extension portion (410-2) and the engaging portion (420-2).

[0198] As illustrated in Fig. 22, the sensor unit (200), the circuit unit (300-2), and the contact maintenance unit (400-2) are coupled to the lower housing (120-2), and the lower housing (120-2) and the upper housing (110-2) can be coupled. Specifically, the lower housing (120-2) and the upper housing (110-2) can be coupled with the protrusions (420-2) and the upper protrusions (520) aligned so that they face each other. When the upper housing (110-2) descends and is coupled with the lower housing (120-2), the upper protrusions (520) are coupled with the protrusions (420-2) in the internal space.

[0199] As the upper housing (110-2) descends, the opposite inclined surface (521) descends in contact with the inclined surface (422), and the first connecting portion (420-2a) and the second connecting portion (420-2b) can be brought into close contact with each other in a direction facing each other.

[0200] Specifically, as the lower housing (120-2) and the upper housing (110-2) are coupled, the first coupling portion (420-2a) can be brought into close contact with the first surface (211a) by the upper protrusion (520). Therefore, the close contact between the first contact portion (320-2a) and the first sensor terminal (230a) can be further strengthened. In addition, the second coupling portion (420-2b) can be brought into close contact with the second surface (211b) by the upper protrusion (520). Therefore, the close contact between the second contact portion (320-2b) and the second sensor terminal (230b) can be further strengthened.

[0201]

[0202] Hereinafter, additional embodiments of the present invention will be described with reference to FIGS. 23 to 39. In the additional embodiments described with reference to FIGS. 23 to 39 below, if overlapping drawing symbols are described with the embodiments described with reference to FIGS. 1 to 22, the overlapping drawing symbols will be described based on the contents described in the additional embodiments below.

[0203] In the description of an additional embodiment, "horizontal direction" refers to a direction roughly parallel to the skin to which the analyte monitoring device of the present invention is attached. Here, it is assumed that the skin to which the analyte monitoring device is attached is flat. Since the analyte monitoring device of the present invention has a lower surface of the housing in close contact with the skin, "horizontal direction" may refer to a direction parallel to the lower surface of the housing.

[0204] In the description of an additional embodiment, "vertical direction" means a direction orthogonal to the horizontal direction and away from the skin. Since the analyte monitoring device of the present invention has a lower surface of the housing in close contact with the skin, "vertical direction" may mean a direction perpendicular to the lower surface of the housing.

[0226]

[0227] Hereinafter, with reference to FIGS. 26 to 35, an analysis monitoring device according to an additional embodiment of the present invention will be described. FIG. 26 is a drawing showing both sides of a sensor unit according to an additional embodiment of the present invention.

[0228] Referring to Fig. 26, the sensor unit (200) may include a connecting unit (210) and a sensing unit (220). The connecting unit (210) may be located in the internal space of the housing (100). Specifically, the connecting unit (210) may be formed in a plate shape that is vertically erected in the internal space of the housing (100). The connecting unit (210) may include a first surface (211) and a second surface (212) that are vertically erected. The first surface (211) and the second surface (212) may correspond to opposite surfaces.

[0229] The connecting portion (210) may include at least one sensor terminal (230). The sensor terminal (230) may be formed on at least one of the first surface (211) and the second surface (212). Referring to FIG. 4, two first sensor terminals (231, 232) are formed on the first surface (211) of the connecting portion (210), and one second sensor terminal (233) is formed on the second surface (212). The surface and position of the sensor terminal formed on the connecting portion (210) may be variously changed.

[0230] The connecting portion (210) may include a sensor connecting portion (215). The sensor connecting portion (215) may be configured to strengthen the bonding between the connecting portion (210) and the contact portion (401) and to fix the position of the connecting portion (210) between the first contact portion (410) and the second contact portion (420).

The form in which the sensor connecting portion (215) and the connecting portions (412a, 422a) of the contact portion (401) are connected will be described in more detail below with reference to FIGS. 28 and 29.

[0231] The sensing portion (220) extends from the connecting portion (210). The sensing portion (220) may extend downwardly from the end of the connecting portion (210). Accordingly, the sensing portion (220) may extend toward the user's skin.

[0232]

[0233] Figure 27 is an exploded perspective view of a contact portion according to an additional embodiment of the present invention.

[0234] Referring to Fig. 27, the contact portion (401) may include a first contact portion (410) and a second contact portion (420) that are separated from each other. The first contact portion (410) and the second contact portion (420) may be formed as separate members and then be joined to each other in close contact with each other with the connecting portion (210) interposed therebetween.

[0235] As illustrated in Fig. 27, the contact portion (401) may be formed in a ring shape that forms a space therein. Specifically, the first contact portion (410) and the second contact portion (420) may be formed in a semicircular shape and may be combined with each other to form a ring-shaped structure.

[0236] At least one of the first contact portion (410) and the second contact portion (420) may function as a transmission contact portion. The transmission contact portion refers to a configuration that not only physically contacts the sensor portion (200), but also performs the function of transmitting data sensed by the sensor portion (200) to the circuit portion (300). The transmission contact portion may include a signal transmission portion coupled to the contact portion body. The signal transmission portion is formed of a conductive material and may electrically connect the sensor terminal (230) and the circuit portion (300).

[0237] In Fig. 27, both the first contact portion (410) and the second contact portion (420) are illustrated as functioning as transmission contact portions. However, in some cases, only one of the first contact portion (410) and the second contact portion (420) may function as a transmission contact portion. If only the first contact portion (410) functions as a transmission contact portion and the second contact portion (420) does not function as a transmission contact portion, the second contact portion (420) may not include a signal transmission portion. In addition, a sensor terminal may not be formed on the second surface (212) of the connection portion (210) of the sensor portion (200) that comes into contact with the second contact portion (420).

[0238] In the following, as illustrated in Fig. 27, the description will be based on the assumption that both the first contact portion (410) and the second contact portion (420) function as transmission contact portions.

[0239] Referring to FIG. 27, the first contact portion (410) includes a first contact portion body (411) and a first signal transmission portion (415). The first contact portion body (411) may include a first contact surface (412), a first circuit connection surface (413), and a first coupling surface (414).

[0240] The first contact surface (412) corresponds to the surface that comes into contact with the connection portion (210) of the sensor portion (200). The first contact surface (412) may be formed on one end of the first contact portion body (411). A sensor connection terminal (415a) of the first signal transmission portion (415) is formed on the first contact surface (412). The sensor connection terminal (415a) of the first signal transmission portion (415) comes into contact with the first sensor terminal (231, 232) formed on the first surface (211) of the connection portion (210).

[0241] The first circuit connection surface (413) corresponds to a surface adjacent to the circuit portion (300). The first circuit connection surface (413) may be formed on the other end of the first contact body (411). A circuit connection terminal (415b) of the first signal transmission portion (415) is formed on the first circuit connection surface (413). The first circuit connection surface (413) may be positioned adjacent to the signal terminal (310) of the circuit portion (300).

[0242] The first coupling surface (414) corresponds to a surface that is in contact with and coupled to the second contact portion (420). The first contact portion (410) is coupled to the second contact portion (420) with the sensor portion (200) interposed therebetween at the first contact surface (412) portion, and can be coupled to and directly coupled to the second contact portion (420) at the first coupling surface (414) portion.

[0243] The first signal transmission unit (415) may be coupled to the first contact body (411). The first signal transmission unit (415) may include a sensor connection terminal (415a) at one end and a circuit connection terminal (415b) at the other end. The sensor connection terminal (415a) of the first signal transmission unit (415) may be formed on the first contact surface (412), and the circuit connection terminal (415b) may be formed on the first circuit connection surface (413).

[0244] Referring to Fig. 27, two first signal transmission parts (415) are coupled to a first contact body (411). The two first signal transmission parts (415) spaced apart from each other can each be in contact with two first sensor terminals (231, 232) formed on the first surface (211) of the connecting part (210).

[0245] The first signal transmission unit (415) is formed of a conductive material. Specifically, the first signal transmission unit (415) may be a plating layer bonded to the first contact unit body (411). The plating layer may be formed on the first contact unit (410) in various ways. The plating layer may be formed by selectively plating the first contact unit body (411) formed of a non-conductive material.

[0246] As an example, the first signal transmission unit (415) may be a plating layer formed using the LDS (Laser Direct Structuring) method. The LDS method is a laser direct structuring method in which a laser is selectively irradiated only to a pattern area where a plating layer is to be formed on a base member, and then a plating layer is selectively formed only in the corresponding pattern area.

[0247] In the present invention, the first contact body (411) may be formed of a resin material containing a specific additive. The specific additive may be a material that is non-conductive but changes to conductive when irradiated with light under specific conditions. Thereafter, light (laser) under specific conditions may be irradiated to an area on the surface of the first contact body (411) where the first signal transmission unit (415) is to be formed. Accordingly, the additive in the area irradiated with light may change to conductive. Thereafter, when the first contact body (411) is immersed in a plating solution, a plating layer is selectively formed only on the area on the surface of the first contact body (411) where the light is irradiated.

[0248] As another example, the first signal transmission portion (415) may be a plating layer formed by a selective etching method. Specifically, the first contact portion (410) may be an injection-molded product composed of a first resin material and a second resin material having different chemical properties. The first contact portion (410) composed of these two types of resin materials may be injection-molded by a double injection method. Here, the area of ​​the surface of the first contact portion body (411) where the first signal transmission portion (415) is to be formed may be formed of the first resin material. When the first contact portion (410) is immersed in a specific etching solution, only the area of ​​the first resin material surface that reacts with the specific etching solution is etched. Thereafter, when the selectively etched first contact portion body (411) is immersed in a plating solution, a plating layer is selectively formed only on the etched area of ​​the surface of the first contact portion body (411).

[0249] The first signal transmission unit (415) can be formed as a plating layer bonded to the surface of the first contact body (411) by various methods other than the above-described method.

[0250] The second contact portion (420) may be formed with a structure identical to or similar to that of the first contact portion (410). The second contact portion (420) includes a second contact portion body (421) and a second signal transmission portion (425). The second contact portion body (421) may include a second contact surface (422), a second circuit connection surface (423), and a second coupling surface (424). The description of the structure of the second contact portion (420) will be replaced with the description of the first contact portion (410).

[0251] The contact portion (401) may include a fastening portion (412a, 422a). The fastening portion (412a, 422a) may be a configuration of a portion where the first contact portion (410) and the second contact portion (420) are coupled. Specifically, the first contact portion (410) and the second contact portion (420) may each include a fastening portion (412a, 422a) that is fitted into each other. The fastening portion (412a, 422a) may be formed at a portion where the first contact portion (410) and the second contact portion (420) are in contact with each other.

[0252] Specifically, the fastening portions (412a, 422a) may be formed on the first contact surface (412) and the second contact surface (422). As illustrated in Fig. 27, a first fastening portion (412a) in the form of a protrusion may be formed on the first contact surface (412), and a second fastening portion (422a) in the form of a groove may be formed on the second contact surface (422). When the first contact portion (410) and the second contact portion (420) are coupled, the first and second fastening portions (412a, 422a) may be fitted together.

[0253] In addition, the fastening portions (412a', 422a') may also be formed on the first coupling surface (414) and the second coupling surface (424). As illustrated in FIG. 5, a first fastening portion (412a') in a groove shape may be formed on the first coupling surface (414), and a second fastening portion (422a') in a protrusion shape may be formed on the second coupling surface (424). When the first contact portion (410) and the second contact portion (420) are coupled, the first and second fastening portions (412a', 422a') may be fitted together.

[0254]

[0256] Referring to FIGS. 28 and 29, the first contact portion (410) and the second contact portion (420) can be tightly coupled to each other with the connecting portion (210) therebetween. Accordingly, the first surface (211) of the connecting portion (210) comes into contact with the first contact surface (412) of the first contact portion (410), and the second surface (212) comes into contact with the second contact surface (422) of the second contact portion (420).

[0257] The connecting portion (210) may be formed in a plate shape that is vertically erected on the lower surface of the housing (100). In addition, the first contact surface (412) and the second contact surface (422) may also be formed as vertical surfaces that are vertically erected on the lower surface. Accordingly, the first contact surface (412), the connecting portion (210), and the second contact surface (422) may be in close contact with each other in the horizontal direction.

[0258] The first signal transmission unit (415) may extend from the sensor connection terminal (415a) to the circuit connection terminal (415b). The sensor connection terminal (415a) of the first signal transmission unit (415) may be formed on the first contact surface (412). In addition, the circuit connection terminal (415b) may be formed on the first circuit connection surface (413).

[0259] The sensor connection terminal (415a) of the first signal transmission unit (415) is in contact with the first sensor terminal (231, 232) formed on the first surface (211) of the connection unit (210), and the circuit connection terminal (415b) can be connected to the signal terminal (310) of the circuit unit (300). Through this, the first signal transmission unit (415) can electrically connect the first sensor terminal (231, 232) and the circuit unit (300).

[0260] The second signal transmission unit (425) may also be formed in the same manner as the first signal transmission unit (415). The sensor connection terminal (425a) of the second signal transmission unit (425) may be in contact with the second sensor terminal (233) formed on the second surface (212) of the connection unit (210), and the circuit connection terminal (425b) may be connected to the signal terminal (310) of the circuit unit (300). Through this, the second signal transmission unit (425) may electrically connect the second sensor terminal (231) and the circuit unit (300).

[0261] The connecting portion (210) of the sensor portion (200) may include a sensor fastening portion (215). The sensor fastening portion (215) may be coupled with fastening portions (412a, 422a). The sensor fastening portion (215) may be formed in a shape such as a groove or an opening. When the first contact portion (410) and the second contact portion (420) are coupled, the fastening portions (412a, 422a) may be fitted and coupled. When the fastening portions (412a, 422a) are coupled, the first fastening portion (412a) formed in a protruding structure among the fastening portions may be coupled by passing between the sensor fastening portions (215). Due to the combination of the sensor connection part (215) and the connection part (412a, 422a), the position of the connection part (210) can be fixed between the first contact part (410) and the second contact part (420).

[0262] Referring to Fig. 29, when the first contact portion (410) and the second contact portion (420) are combined, a sensor receiving space (402) can be formed inside the contact portion (401). The connecting portion (210) can extend between the first contact surface (412) and the second contact surface (422) to the sensor receiving space (402) and to the sensing portion (220).

[0263] When the first contact portion (410) and the second contact portion (420) are combined, the first circuit connection surface (413) and the second circuit connection surface (423) can be positioned on the same plane. Accordingly, the circuit connection terminals (415b, 425b) formed on the first circuit connection surface (413) and the second circuit connection surface (423) can be combined with a plurality of signal terminals (310) arranged in a row through solder or the like.

[0270] As illustrated in Fig. 31, when the contact portion (430) is coupled with the contact portion (401), the elastic portion (433) may be deformed. The elastic portion (433) may apply an external force to push the contact portion (401) toward the inside of the bracket (431) by means of a restoring force. Accordingly, the first contact portion (410) and the second contact portion (420) may be brought into close contact with each other in a direction facing each other.

[0271] The bracket (431) of the sealing member (430) may be formed with at least one opening (432). The opening (432) may be formed as an opening connecting the inside and the outside of the bracket.
