Description

Technical Field

[0001] The present invention relates to an analyte monitoring device, and more particularly to a device for being inserted into the body to monitor an analyte.

Background Art

[0002] Recently, due to the increasing preference for processed foods, people are easily exposed to simple sugars. Because of such an environment, diabetes has also increased rapidly. When blood sugar drops suddenly or rises suddenly, diabetic patients may be shocked and may rarely even die. Accordingly, diabetic patients need to continuously monitor their blood sugar.

[0003] In the case of conventional blood glucose meters, a lancet is used to incise a fingertip, and the blood of a diabetic patient coming out from the incised gap is inserted into a blood glucose analyzer to calculate the blood sugar.

[0004] Such a blood glucose meter provides pain and fear to the user. Also, it is practically difficult to wound one's finger every hour to draw blood.

[0005] To solve such problems, a continuous glucose monitoring (CGM) device has been developed. When a sensor having a fine thickness and an electronic device for analyzing an analyte (hereinafter, "blood sugar") measured by the sensor are attached to the skin of a diabetic patient, the blood sugar is continuously measured over a period of one week to half a month.

[0006] A continuous glucose monitoring device is inserted and attached to the skin of the body, and continuous blood sugar measurement is possible with a sensor provided in the device. Generally, efforts have been continuously made to miniaturize the continuous glucose monitoring device in order to insert and attach it to the skin of the body.

[0007] Conventional continuous glucose monitoring devices used either semiconductor sensors or mechanical switches for battery power supply. However, using semiconductor sensors required additional battery drain, and using mechanical switches instead of semiconductor sensors presented a problem: mechanical failures could occur if the mechanical switch was stored in a pressed state for extended periods. [Overview of the project] [Problems that the invention aims to solve]

[0050] Hereinafter, an embodiment of the analytical material monitoring apparatus according to the present invention will be described in detail with reference to the attached drawings. In the description with reference to the attached drawings, identical or corresponding components will be assigned the same drawing number, and redundant explanations will be omitted.

[0051] Figure 1 shows an analyte monitoring device according to one embodiment of the present invention, Figure 2 shows the coupled state of the needle part and transmitter of the analyte monitoring device according to one embodiment of the present invention, and Figure 3 shows the separated state of the needle part and transmitter of the analyte monitoring device according to one embodiment of the present invention.

[0052] As shown herein, an analyte monitoring device according to one embodiment of the present invention includes a housing 10, 12, a substrate 30 installed inside the housings 10, 12, a needle portion 20 including a needle body 22 movably installed inside the housings 10, 12 and a needle 24 provided at the lower end of the needle body 22 and inserted into the body, and a sensing portion 40 disposed either inside or outside the housings 10, 12 and conductive in contact with the needle portion 20, wherein when the needle portion 20 is fired and separated from the sensing portion 40, a wake-up trigger for power supply can be transmitted to the substrate 30.

[0053] The housings 10 and 12 may include, but are not limited to, a lower housing 10 and an upper housing 12 coupled to the upper part of the lower housing 10, and the housings 10 and 12 may be formed as a single unit. An opening may be formed in the central portion of the lower housing 10 through which the needle 24 passes. The lower housing 10 may be made of a material that deforms to conform to the body as a surface that comes into contact with the body, and the outer surface of the lower housing 10 may have an adhesive-coated bonding surface so that the analyte monitoring device can be attached to the body surface.

[0054] The upper housing 12 is coupled to the lower housing 10 and protects the various components mounted on the lower housing 10. The upper housing 12 is pressurized by an applicator, i.e., a tool on which the analyte monitoring device is mounted so that the sensor 42 of the analyte monitoring device is inserted into the user's body, and the pressurization can cause the analyte monitoring device to adhere to the body. The upper housing 12 may be made of synthetic resin, such as plastic, but is not limited to this, and can be made of a variety of materials.

[0055] The needle portion 20 includes a needle body 22 and a needle 24 provided at the tip of the needle body 22. The needle portion 20 moves linearly, either forward or backward, by the applicator. When the needle portion 20 is fired, the needle 24 is inserted into the body, and a sensor 42 located inside the needle 24 may be penetrated. The needle 24 will incise the skin so that at least a portion of its tip penetrates the body along the insertion direction, guiding the sensor 42 into the body. The sensor 42 will be inserted into the body to measure information about analytes inside the body. The sensor 42 can be inserted into the body to measure information about analytes inside the body, such as glucose, and the measured information can be transmitted to the substrate 30 through the needle body 22.

[0056] The substrate 30 is mounted on the inner surface of the lower housing 10 and provides an electrical connection between the components mounted on the substrate 30 and the sensor 42. Analytical information measured by the sensor 42 can be transmitted to the substrate 30, which can process the transmitted electrical signals in a predetermined manner. Although the substrate 30 is shown mounted on the inner surface of the lower housing 10 in a disc shape, it is not limited to this and can be formed in a variety of shapes.

[0057] The holder 32 connects to the needle portion 20 and serves to fix the needle portion 20 to the lower housing 10. The holder 32 aligns the needle portion 20 so that it is fixed to the lower housing 10 and the needle 24 is inserted vertically downward. In one embodiment, the holder 32 may be made of rubber packing to fix the needle portion 20. In one embodiment, the holder 32 may be formed so that the rubber packing surrounds only the edge portion.

[0058] The battery 34 is connected to the substrate 30 and can supply power to the analyte monitoring device. In this drawing, the battery 34 is shown as being formed in a disc shape, but it is not limited to this, and the battery 34 can have a variety of shapes. In this embodiment, when the needle portion 20 is separated by firing, the battery 34 can supply power to the substrate 30 by the wake-up trigger operation of the substrate 30.

[0059] The sensing unit 40 can be mounted on the inner surface of the lower housing 10. The sensing unit 40 is mounted on the inner surface of the lower housing 10, but can be positioned in a location corresponding to the position of the needle unit 20. That is, the sensing unit 40 is positioned directly below the needle unit 20, and as the needle unit 20 moves forward, it can conduct electricity while in contact with the needle unit 20, as shown in Figure 3. In the case of an analyte monitoring device, before use, the needle unit 20 or holder 32 maintains a state of contact with the sensing unit 40, and during use, it is ejected by the applicator and eventually separated from the sensing unit 40.

[0060] In one embodiment, the sensing unit 40 may be fabricated from QTC (Quantum Tunneling Composite). Quantum tunneling composite material (QTC) is a flexible polymer exhibiting excellent electrical properties and used as a pressure sensor and switching system, and is a composite material of a metal and a non-conductive elastomer binder used as a pressure sensor. QTC essentially utilizes the principle of quantum tunneling, which has been widely applied in applied physics, and a quantum tunneling composite sheet may consist of three layers: a QTC layer, a conductor layer, and an insulator. When force is applied to the plastic insulator surface of the QTC, electrons can be tunneled from the conductor layer to the QTC layer, making it conductive.

[0061] In this embodiment, QTC material is presented as one embodiment of the sensing unit 40, but it is not limited to this. Any material can be used for the sensing unit 40 as long as it is a touch sensor that can conduct electricity through contact with the needle unit 20 and transmit a wake-up trigger signal. Furthermore, although the sensing unit 40 is shown in this embodiment as being mounted inside the lower housing 10, it is not limited to this, and may be mounted outside the lower housing 10, or both inside and outside the lower housing 10.

[0062] Thus, when the sensing unit 40 comes into contact with the needle unit 20 due to the forward movement of the needle unit 20, the sensing unit 40 becomes conductive, but at this time, it is in the switch-off state and electrically disconnected from the substrate 30. Subsequently, when using the analyte monitoring device, the needle unit 20 is ejected using the applicator, and the needle 24 is inserted into the body to guide the invasion of the sensor 42. Then, the needle unit 20 is withdrawn from the body and physically separated from the sensing unit 40. At this time, when the pressure transmission of the needle unit 20 to the sensing unit 40 is released, it switches on and transmits a wake-up trigger signal to the substrate 30. In this way, power is supplied to the substrate 30 from the battery 34. In a miniaturized analyte monitoring device, it is necessary to supply power automatically, and since the battery 34 operates due to the ejection and separation operation of the needle unit 20, automatic power supply to the substrate 30 is possible.

[0063] On the other hand, the sensing unit 40 presented in this embodiment may be circular with a predetermined volume as shown in the drawing, but is not limited thereto. That is, the sensing unit 40 can be any shape as long as it can be contacted by the advance of the needle unit 20. For example, the sensing unit 40 may have a cross-section such as a square or triangle, or it may be planar without any volume. In addition, multiple sensing units 40 may be arranged on the inner surface of the lower housing 10 and contacted by the needle unit 20. Furthermore, the sensing unit 40 may have a shape that surrounds the holder 32.

[0064] Figure 4 shows an analyte monitoring device according to another embodiment of the present invention, Figure 5 shows the coupled state of the needle part and transmitter of the analyte monitoring device according to another embodiment of the present invention, and Figure 6 shows the separated state of the needle part and transmitter of the analyte monitoring device according to another embodiment of the present invention.

[0065] Referring to this, an analyte monitoring device according to another embodiment of the present invention includes housings 10, 12, a substrate 30 installed inside the housings 10, 12, a needle body 22 movably installed inside the housings 10, 12, a needle portion 20 including a needle 24 provided at the lower end of the needle body 22 and inserted into the body to penetrate a sensor 42, a first conductive portion 26 disposed on the lower surface of the needle body 22, and a second conductive portion 44 disposed either inside or outside the housings 10, 12 and conductive in contact with the needle portion 20, wherein when the needle portion 20 is fired and separated from the second conductive portion 44, a wake-up trigger for power supply can be transmitted to the substrate 30.

[0066] A first conductive portion 26 is provided on the lower surface of the needle body 22 of the needle portion 20. A second conductive portion 44 corresponding to the first conductive portion 26 is provided on the inner surface of the lower housing 10. The second conductive portion 44 may be positioned vertically below the forward movement of the needle portion 20. That is, the second conductive portion 44 may be positioned in the same location as the sensing portion 40 in the above-described embodiment, and may have a shape that surrounds the holder 32.

[0067] As the needle portion 20 moves forward, the first conductive portion 26, positioned in this manner, comes into contact with the second conductive portion 44 and becomes conductive. In the case of an analyte monitoring device, the first conductive portion 26 remains in contact with the second conductive portion 44 before use, and is ejected by the applicator during use, ultimately separating from the second conductive portion 44.

[0068] On the other hand, the first conductive part 26 and the second conductive part 44 can be made from a conductive material. In one embodiment, the first conductive part 26 and the second conductive part 44 can be made from conductive silicone rubber. In another embodiment, the first conductive part 26 and the second conductive part 44 can be made from conductive polymer material, conductive elastomer, conductive tape, conductive metal spring pin, carbon nanotube, or metal-polymer composite.

[0069] Thus, in this embodiment, by not applying semiconductor sensors or mechanical switches to the power supply of the analyte monitoring device and instead utilizing the contact and separation of the conductive material sensing part 40 and conductive parts 26 and 44, power can be automatically supplied from the time the product is used, potentially improving the durability of the device during storage and use.

[0070] Figure 7 is an exploded perspective view showing an analyte monitoring device according to another embodiment of the present invention, Figure 8 is a diagram showing an analyte monitoring device according to another embodiment of the present invention, Figure 9 is a diagram showing the upper surface of the upper housing of an analyte monitoring device according to another embodiment of the present invention, and Figure 10 is a diagram showing the lower surface of the upper housing of an analyte monitoring device according to another embodiment of the present invention. In these drawings, components identical to those in the above-described embodiments are given reference numerals in the hundreds, and detailed explanations are omitted for convenience.

[0071] Referring to this, another embodiment of the present invention provides an analyte monitoring device comprising: housings 110, 112; a needle body 122 movably installed inside the housings 110, 112; a needle portion 120 including a needle 124 provided at the lower end of the needle body, which is inserted into the body and penetrates a sensor 42; and a first terminal portion 150 provided in the housings 110, 112, to which the needle portion 120 is fixedly installed. The transmitter holder 200 (Figure 14) is provided with a second terminal portion 240 (Figure 14) which is coupled to the upper part of the housings 110 and 112 and contacts the first terminal portion 150 when coupled to the upper part of the housings 110 and 112, and the transmitter holder 200 (Figure 14) is provided with a second terminal portion 240 (Figure 14) which contacts the first terminal portion 150 when coupled to the upper part of the housings 110 and 112, and the transmitter holder 200 (Figure 14) is provided with a second terminal portion 240 (Figure 14) which contacts the first terminal portion 150 when coupled to the upper part of the housings 110 and 112, and the transmitter holder 200 (Figure 14) is provided with a second terminal portion 240 (Figure 14) which is coupled to the upper part of the housings 110 and 112, and the transmitter holder 20 is provided with a second terminal portion 240 (Figure 14) which contacts the first terminal portion 150 when coupled to the upper part of the housings 110 and 112, and the transmitter holder 200 (Figure 14) is provided with a second terminal portion 240 (Figure 14) which contacts the first terminal portion 150 when coupled to the upper part of the housings

[0072] In this embodiment, the upper housing 112 has a cut portion 114 in which the needle coupling portion 116 is arranged. The cut portion 114 is formed by cutting a part of the upper housing 112 from the central side to the lateral side, and can be cut to have a predetermined width, but is not limited to this.

[0073] A needle coupling portion 116, to which the needle portion 120 is attached, is positioned on the incision portion 114. The needle coupling portion 116 is attached to the lower housing 110, but it will be located on the incision portion 114 when the upper housing 112 is attached to the lower housing 110.

[0074] The needle coupling portion 116 is equipped with a holder 132 for fixing the needle portion 120 when it is coupled. As described above, the holder 132 is provided so as to be surrounded by a rubber packing, which allows the needle portion 120 to be stably fixed.

[0075] On the other hand, the first terminal portion 150 may be arranged across the upper surface, inner surface, and lower surface of the upper housing 112. More specifically, the first terminal portion 150 may include a first-first terminal 152 arranged on the upper surface of the upper housing 112, a first-second terminal 154 extending from the first-first terminal 152 and arranged on the side surface of the incision portion 114 or the inner surface of the upper housing 112, and a first-third terminal 156 extending from the first-second terminal 154 and arranged on the lower surface of the upper housing 112.

[0076] The first terminal portion 150 is configured as described above so that it is exposed on the upper side of the upper housing 112 and in contact with the second terminal portion 240 (Figure 14) of the transmitter holder 200 (Figure 14). At the same time, the first terminal portion 150, which is in contact with the second terminal portion 240 (Figure 14), is exposed on the lower side of the upper housing 112 and in electrical contact with the substrate 130. The first terminal portion 150 can be extended in pairs in parallel as shown in the drawing, but is not limited to this, and three or more may be extended in parallel.

[0077] Here, the first terminal portion 150 can be patterned using the LDS (Laser Direct Structuring) method. The LDS (Laser Direct Structuring) method is a method in which a pattern is selectively processed on a thermoplastic resin using a laser, and then the reliability of the electrical characteristics is ensured through a plating process. On the other hand, although the pattern of the first terminal portion 150 is shown as a pair arranged in parallel as described above, it is not limited to this, and may be formed so that a part of it is bent depending on the position on the substrate 130.

[0078] Figure 11 shows an analyte monitoring device according to the present invention or another embodiment, and Figure 12 shows the lower surface of the upper housing of the analyte monitoring device according to the present invention or another embodiment.

[0079] Referring to this, in this embodiment there are some differences in the shape of the incision portion 114 and the needle connection portion 116 compared to the embodiment described above. However, these differences in shape do not result in any technical differences. In this drawing, the width of the needle connection portion 116 is not formed to be constant and may be formed to be fan-shaped, but it is not limited to this.

[0080] Furthermore, in this embodiment, the first to third terminals 156 constituting the first terminal portion 150 may be formed so that they do not extend in one direction on the lower surface of the upper housing 112, but are bent in at least a portion. Of course, this may vary depending on the position where the first to third terminals 156 are connected to the substrate 130.

[0081] Figure 13 is an exploded perspective view showing an analyte monitoring device according to another embodiment of the present invention, and Figure 14 is a view showing the lower surface of the transmitter holder of the analyte monitoring device according to another embodiment of the present invention.

[0082] Referring to this, the transmitter holder 200 is coupled to the housings 110 and 112 and is configured to cause the housings 110 and 112 to move linearly from distal to proximal. On the other hand, the transmitter holder 200 moves only in the direction from distal to proximal. The transmitter holder 200 is provided with a holder penetration portion 210 through which the needle portion 120 passes.

[0083] Furthermore, the lower surface of the transmitter holder 200 may be provided with a second terminal portion 240 that contacts the first terminal portion 150 when coupled to the upper part of the housings 110 and 112. The second terminal portion 240 may be positioned in a location corresponding to the position of the first terminal portion 150. In this way, when the transmitter holder 200 is coupled to the housings 110 and 112, the first terminal portion 150 and the second terminal portion 240 can come into contact and be electrically connected.

[0084] In the case of the analyte monitoring device, before use, the transmitter holder 200 is coupled to the housings 110 and 112, maintaining contact with the first terminal 150 and the second terminal 240. During use, it is ejected by the applicator and eventually separated from the first terminal 150. Once separated from the first terminal 150, it transmits a wake-up trigger for power supply to the circuit board 130.

[0085] The cap 300 is configured to be attached to or detached from a handle (not shown) and can protect the inside of the applicator from external contaminants and impacts. The cap 300 may be formed in a hollow cylindrical shape and is equipped with a cap holder 310 inside. The cap holder 310 serves to align the coupled transmitter holder 200 so that it is fixed in place.

[0086] Figure 15 is an exploded perspective view showing an analyte monitoring device according to the present invention and other embodiments.

[0087] Referring to this, in this embodiment, a second terminal portion 126 that contacts the first terminal portion 150 is provided on the needle portion 120. That is, the second terminal portion 126 may be provided on the lower surface of the needle body 122 that constitutes the needle portion 120.

[0088] As the second terminal portion 126 is provided on the lower surface in this manner, the second terminal portion 126 will come into contact with the first terminal portion 150 during the coupling process of the needle portion 120. In other words, unlike the embodiment described above, this embodiment is configured such that terminal contact does not occur on the transmitter holder 200 side, but directly on the needle portion 120 side.

[0089] To this end, the second terminal portion 126 may be provided in a disc shape on the lower surface of the needle body 122, but is not limited to this. Furthermore, the second terminal portion 126 may have a diameter larger than the diameter of the lower surface of the needle body 122 in order to contact the first terminal portion 150. That is, the second terminal portion 126 may protrude radially from the lower surface of the needle body 122 and smoothly contact the first terminal portion 150.

[0090] Although the above has been described with reference to specific embodiments of the present invention, a person with ordinary skill in the art will understand that the present invention can be modified and altered in various ways without departing from the spirit and scope of the invention as described in the following claims.
