Description

Transmitter and insertion device assembly including the same

[0001] The present invention relates to a transmitter of a device for monitoring analytes in the body and an insertion device assembly for inserting a sensor of the transmitter into a user's body and attaching the transmitter to the outside of the user's body.

[0002]

[0003] The material described in this article merely provides background information for the present invention and does not constitute prior art.

[0004] With the recent rise in processed foods, people are increasingly exposed to simple sugars. This environment has also led to a sharp rise in diabetes. Sudden drops or spikes in blood sugar levels can lead to shock in diabetic patients, and in rare cases, death. Therefore, diabetic patients need to continuously monitor their blood sugar levels.

[0005] In the case of conventional blood sugar measuring devices, a lancet is used to make an incision at the tip of the finger, and the blood of the diabetic patient that comes out through the incision is inserted into a blood sugar analysis device to calculate the blood sugar level.

[0006] This type of blood glucose measuring device causes pain and fear to the user. Furthermore, it is unrealistic to prick your finger every hour to draw blood.

[0007] To address these issues, a continuous glucose monitoring (CGM) system was developed. By attaching a microscopic sensor and an electronic device (hereinafter, "transmitter") for analyzing the analyte (hereinafter, "blood sugar") measured by the sensor to the skin of a diabetic patient, blood sugar levels are continuously measured for a period of one to ten days.

[0008] The transmitter's sensor is very thin, making it difficult to directly penetrate the skin. Therefore, a device (hereinafter referred to as an "applicator") is needed to wrap the sensor around a needle, insert the sensor and needle together, and then withdraw the needle.

[0009] Meanwhile, according to US 2021-0038131 A1, the user must insert the sensor introducer (sensor introducer 106) into the sensor inserter (sensor inserter 500). At this time, the sensor introducer must be oriented correctly and inserted into the sensor inserter, which can cause fatigue for the user. Therefore, it is preferable that the insertion device assembly be manufactured with the applicator and transmitter integrated into one unit.

[0010] Sterilization is performed during the assembly process to form the transmitter and applicator as one unit. However, sterilization of the applicator using sterilizing gas takes a long time and there is a risk of residue remaining.

[0011] For this reason, a method of sterilizing medical devices by irradiating them with E-beam (Electron-beam) is widely used. E-beam sterilization is a method of sterilizing by accelerating electrons and colliding them with the object to be sterilized, resulting in heat. It allows for rapid sterilization and, unlike the sterilization gas method, does not leave residue after sterilization, so it has the advantage of being able to be released and distributed immediately after sterilization without delay.

[0012] On the other hand, there is a problem that the electronic components such as the battery and circuit board inside the transmitter may be affected by the electrons irradiated during sterilization.

[0013] JP 7210614 B2 discloses a method of using a shield to protect a sensor control device (transmitter) including a sensor control device having built-in sensors and electrical components from a sterilizing E-Beam, in which the sensor control device is shielded on one side of the transmitter and only the sensor is exposed to be sterilized.

[0014] This can protect the sensor control device from the sterilizing E-Beam, but there is also the problem that a separate shield must be provided, and the structure of the shield cannot completely block the E-Beam.

[0051]

[0052] According to the transmitter of the present invention and the insertion device assembly including the same, the following effects can be obtained.

[0053] 1) First, by dividing the transmitter into a sensor assembly and an electronic assembly and configuring them separately, sterilization of only the sensor assembly is possible without a separate shielding device.

[0054] 2) By dividing the transmitter into a sensor assembly and an electronic assembly and configuring them separately, the sensor and needle, which are the parts directly inserted into the user's body, and the lower surface of the transmitter and the lower surface of the applicator, which come into contact with the user's skin, are modularized as the first assembly, making it possible to sterilize the parts requiring sterilization with just one E-Beam irradiation.

[0055] 3) By dividing the transmitter into a sensor assembly and an electronic assembly and configuring them separately, the electronic components that may lose some functions when directly exposed to the E-beam are mounted on the board, and the components such as the upper housing or driving part of the applicator that have little need for sterilization are practically excluded from the first assembly, so that sterilization according to the E-beam is performed, and there is no concern that the electronic devices mounted on the board will break down, and there is an advantage in that the insertion device assembly can be sterilized with only a short E-beam irradiation in a narrow area.

[0056] 4) After sterilization of the sensor assembly, the electronic assembly can be easily connected to the sensor assembly using a simple method such as hook connection or bonding connection, so that even if the transmitter is configured by separating the sensor assembly and the electronic assembly, the assembly and sterilization processes can be performed quickly and easily.

[0057] 5) Since the transmitter is divided into a sensor assembly and an electronic assembly, the lower surface of the transmitter is composed of two parts: a base and a lower case, so that the force applied to the substrate contained within the transmitter when triggered through the applicator is distributed and reduced.

[0058] 6) By arranging terminals and electrodes that electrically connect between the sensor assembly and the electronic assembly so that they are connected during assembly, the sensor and the substrate can be electrically connected without a separate electrical connection work at the same time as the sensor assembly and the electronic assembly are combined.

[0059] 7) By configuring the connector connecting the electrode and terminal to the sensor in the form of a clip, it is possible to electrically connect the sensor and the electrode and terminal using the connector without a separate configuration for fixing the sensor, and at the same time fix the sensor to the sensor assembly.

[0060] 8) In addition, the operation activation conversion of the transmitter is possible by installing a conversion terminal and an activation terminal so that the transmitter is separated from the applicator.

When designating components in each drawing, it should be noted that, where possible, identical components will be given identical reference numbers, even if they appear in different drawings. Furthermore, when describing the present invention, detailed descriptions of known related components or functions will be omitted if they are deemed to obscure the gist of the present invention.

[0086] In describing components of embodiments according to the present invention, symbols such as first, second, i), ii), a), b) may be used. These symbols are only for distinguishing the components from other components, and the nature, order, or sequence of the components are not limited by the symbols. When a part in the specification is said to "include" or "have" a component, this does not mean that other components are excluded, but rather that other components may be included, unless explicitly stated to the contrary.

[0087] In the following description, “insertion device assembly” means an assembly in which the applicator and transmitter are assembled.

[0088] Furthermore, "distal position" refers to a position that is relatively farther from the skin than "proximal position." Meanwhile, distal and proximal are concepts of relative positions, meaning that one element can be understood as being both proximal and distal to another.

[0089] Additionally, “fire” refers to the user’s action of activating the applicator to cause the needle to be inserted into the user’s skin.

[0090] Additionally, “retraction” refers to the process by which the needle returns to its original position after being inserted into the user’s skin.

[0091] Also, "upward" means the direction from proximal to distal.

[0092] Also, "downward" means the direction from distal to proximal.

[0093] Additionally, "horizontal" refers to the plane that the applicator contacts when used, and may refer to the skin surface. In this disclosure, the curvature of the skin surface is not considered, and the description assumes that the user's skin surface is flat.

[0094]

[0095] 1. Transmitter configuration

[0096] Hereinafter, with reference to the attached drawings 1 to 10, the configuration of the transmitter (200) of the insertion device assembly according to one embodiment of the present invention will be described in detail.

[0097] The transmitter (200) includes a sensor (214) formed with a fine thickness and inserted into the user's skin, and electronic components necessary to analyze and transmit analytes measured from the sensor (214).

[0098] A transmitter (200) according to one embodiment of the present invention includes a sensor assembly (210) and an electronic assembly (250) coupled to an upper portion of the sensor assembly (210).

[0099] Referring further to FIG. 3, the configuration of the sensor assembly (210) is described in detail.

[0100] The sensor assembly (210) includes a base portion (211), a sensor (214), a holder (220), an electrode portion (215), a connector (222), and a sensor housing (227).

[0101] The base part (211) is configured in a plate shape. In FIGS. 2 and 3, the base part (211) configured in a circular plate shape is illustrated, but is not limited thereto.

[0102] The base part (211) has an outer wall (212) extending upward from its circumference at a predetermined interval, and a part of the outer wall (212) may be configured as a fastening hook (213).

[0103] A through hole is formed on one side of the base portion (211) for the proximal portion (214a) of the sensor (214) to be positioned through it.

[0104] The sensor (214) is positioned on the base portion (211). Specifically, the proximal portion (214a) of the sensor (214) is positioned to penetrate the through hole of the base portion (211) and be exposed to the lower portion of the base portion (211), and the distal portion (214b) of the sensor (214) extends from the proximal portion (214a) and is positioned on one side of the upper portion of the base portion (211).

[0105] The holder (220) is positioned above the sensor (214) on the base portion (211). The holder (220) is positioned to surround a portion of the upper portion of the sensor (214) at the portion where the sensor (214) penetrates the through hole. Specifically, a portion between the proximal portion (214a) and the distal portion (214b) of the sensor (214) is inserted and positioned within a groove (221) formed at the bottom of the holder (220).

[0106] The holder (220) is made of an elastic material at least in its upper part, so that the needle (171) of the applicator can be positioned by penetrating the upper surface of the holder (220) (see FIG. 11), and when the needle (171) is withdrawn after being attached to the user's body, the penetrating portion can be closed by elasticity.

[0107] The configuration of the electrode portion (215) and the connector (222) will be described in detail with further reference to FIGS. 4 to 6.

[0108] The electrode portion (215) is located on both sides of the sensor (214) on one side of the base portion (211). The electrode portion (215) includes a contact terminal (216) and a connection terminal (217).

[0109] The contact terminals (216) are positioned close to each other on both sides of the sensor (214), and the connection terminals (217) are positioned to extend from the contact terminals (216) to the other side, and the contact terminals (216) and the connection terminals (217) are electrically connected.

[0110] As shown in Fig. 5, the contact terminal (216) may be configured in multiple pieces, and the connection terminal (217) may be configured in multiple pieces of connection terminal (217) that are each electrically connected to the multiple contact terminals (216).

[0111] In FIGS. 4 to 6, contact terminals (216) each consisting of three or two groups on both sides of the sensor (214) and connection terminals (217) each consisting of three or two groups electrically connected to the corresponding terminals are shown, but the present invention is not limited thereto.

[0112] Some of the multiple contact terminals (216) may be internal terminals (218) electrically connected to the sensor (214) by a connector (222), and others may be external terminals (219) connected by a conversion terminal (229) described later.

[0113] In Fig. 5, it is shown that two of the contact terminals (216) of the five contact terminals (216) are arranged in three groups, and one is arranged as an external terminal (219) and one is arranged as an internal terminal (218), but this is not limited thereto.

[0114] The connector (222) is located on the base (211) and electrically connects the sensor (214) and the contact terminal (216).

[0115] The connector (222) includes a sensor contact portion (223) and a terminal contact portion (224), and the sensor contact portion (223) and the terminal contact portion (224) are composed of a plurality of contact portions that extend from the central portion of the connector (222) and are connected.

[0116] The sensor contact portion (223) is positioned to contact one side of the sensor (214), and the terminal contact portion (224) contacts the contact terminal (216), thereby electrically connecting the sensor (214) and the contact terminal (216).

[0117] As shown in Fig. 6, the base portion (211) has an installation portion (225) protruding on one side, and the sensor contact portion (223) is installed so that one side of the sensor (214) is supported on one side of the installation portion (225) and the sensor contact portion (223) is in contact with the other side of the sensor (214), so that the sensor (214) is fixed between the sensor contact portion (223) and the installation portion (225).

[0118] In addition, the connector (222) is formed with a bent portion that is formed by extending the sensor contact portion (223) and the terminal contact portion (224). That is, it is configured in the form of a clip that can be fitted into the installation portion (225).

[0119] A protruding installation hook (226) is positioned on one side of the installation part (225), and when the connector (222) is fitted into the installation part (225), the bending part is engaged with the installation hook (226), so that the connector (222) can be fixedly installed on the installation part (225).

[0120] The configuration of the sensor housing (227) is described with further reference to FIGS. 7 and 8.

[0121] The sensor housing (227) is positioned to cover the upper portion of the base portion (211). However, the sensor housing (227) does not cover the entire upper portion of the base portion (211), but is configured to cover one side of the base portion (211), and specifically, is positioned to cover the upper portion of the sensor (214), the connector (222), and the contact terminal (216) on the upper portion of the base portion (211).

[0122] As shown in FIG. 3 and FIG. 7, an opening (228) is formed on one side of the upper surface of the sensor housing (227), so that when the sensor (214) is positioned to cover the upper portions of the sensor (214), the connector (222), and the contact terminal (216), the upper surface of the holder (220) is exposed through the opening (228).

[0123] The sensor housing (227) includes a conversion terminal (229) and an activation terminal (231).

[0124] The conversion terminal (229) extends from the inside of the sensor housing (227) so that the proximal side comes into contact with a part of the contact terminal (216), i.e., the external terminal (219).

[0125] The activation terminal (231) extends to the other side of the conversion terminal (229) and is exposed to the outside of the sensor housing (227), and the activation terminal (231) is brought into contact with or released from contact with a conductor (not shown) included in the applicator, depending on the operation of the applicator described below.

[0126] Specifically, when the transmitter (200) is installed in the applicator and the conductor and the activation terminal (231) are in contact before the triggering, the operation of the transmitter (200) is deactivated, and when the transmitter (200) is attached to the user's body by the triggering of the applicator and is separated from the applicator, the contact between the conductor and the activation terminal is released, and the operation of the transmitter (200) is activated.

[0127] Additionally, although not shown, the base portion (211) may include all or part of an adhesive tape on its lower surface, and the transmitter (200) may be attached to the user's skin by the adhesive tape while the sensor (214) is inserted into the user's body.

[0128] Next, referring further to the attached drawings 9 and 10, the configuration of the electronic assembly (250) of the transmitter (200) is described.

[0129] The electronic assembly (250) is detachably mounted on the upper portion of the base portion (211) of the sensor assembly (210), and the electronic assembly (250) includes a lower case (252), an upper case (251), and a substrate (255).

[0130] The upper case (251) and the lower case (252) are joined vertically to form the exterior of the electronic assembly (250), and a predetermined receiving space is formed between the joined upper case (251) and the lower case (252).

[0131] The shape of the upper case (251) and the lower case (252) corresponds to the shape of the base part (211) of the sensor assembly (210), but one side thereof may be opened in a shape corresponding to the shape of the sensor housing (227) so that the electronic assembly (250) can be positioned parallel to the sensor housing (227) while being coupled to the upper part of the base part (211).

[0132] The substrate (255) is located inside the space formed between the upper case (251) and the lower case (252).

[0133] It is preferable that the shape of the substrate (255) be formed in a shape corresponding to the upper case (251) and the lower case (252), i.e., in a shape with one side open, so that it can be positioned in the space between the upper case (251) and the lower case (252).

[0134] The substrate (255) is equipped with each electronic component for analyzing the concentration of the user's body analyte detected by the sensor (214) and transmitting information related to the concentration to an external device, and a battery (256) for supplying power to the electronic components.

[0135] The type of substrate (255) is not limited, but may be composed of a PCB (Printed Circuit Board), for example.

[0136] On one side of the substrate (255), a circuit terminal (257) is positioned to transmit a signal of an analyte measured by a sensor (214) or a mode conversion signal from the outside to each electronic component on the substrate (255), and the circuit terminal (257) is composed of the same number of terminals as the contact terminal (216) described above.

[0137] A connection electrode (254) is positioned on one side of the lower case (252), that is, on the part where the circuit terminal (257) of the substrate (255) is located when the substrate (255) is accommodated, and is in contact with the circuit terminal (257) of the substrate (255).

[0138] In addition, a recessed hook (253) is formed on the circumference of the lower case (252), and the hook (253) is formed in a position and number corresponding to the position and number of the fastening hook (213) located in the base (211).

[0139] When the electronic assembly (250) is coupled to the sensor assembly (210), the lower case (252) portion of the electronic assembly (250) is inserted into the outer wall (212) of the base portion (211), and the fastening hook (213) of the base portion (211) is coupled by being hooked to the hook (253) of the lower case (252).

[0140] In a state where the electronic assembly (250) is coupled to the sensor assembly (210), the substrate (255) located inside the electronic assembly (250) is placed on the lower case (252), and is therefore located at a position higher than a predetermined height of the outer wall (212) of the base portion (211) and higher than the upper portion of the outer wall (212).

[0141] That is, since the lower case (251) and the base portion (211) of the electronic assembly (150) are overlapped and placed under the substrate (255), the shock applied to the substrate (255) can be absorbed, and the substrate (255) can be accommodated more stably inside the transmitter (200).

[0142] When the sensor assembly (210) and the electronic assembly (250) are combined, the analyte signal measured by the sensor (214) is transmitted to the electronic component mounted on the substrate (255) through the connector (222), the contact terminal (216), the connection terminal (217), the connection electrode (254), and the circuit electrode.

[0143]

[0144] 2. Applicator composition

[0145] The configuration of the applicator is described with reference to FIGS. 11 to 13.

[0146] The applicator includes an upper housing (110), a lower housing (140), a needle assembly, and a driving unit (150).

[0147] The upper housing (110) is configured to be gripped by the user, and is preferably approximately cylindrical in shape, and the lower portion of the upper housing (110) is open.

[0148] The lower housing (140) is configured to form a space inside by being joined to the lower part of the upper housing (110), and one lower side of the lower housing (140) is placed inside the cap (130).

[0149] The lower housing (140) is coupled to the lower portion of the upper housing (110), and a transmitter (200) is mounted in the internal space formed therein.

[0150] In this state, as described above, the conductor (not shown) installed in the applicator is in contact with the activation terminal of the transmitter, and the operation of the transmitter is disabled.

[0151] When the applicator is used, when the cap (130) is removed from the lower housing (140), the insertion device assembly is ready for use by the user, and the lower surface of the lower housing (140) is used in direct contact with the user's skin.

[0152] The needle assembly includes a grip portion (172) and a needle (171). The needle assembly is positioned in an internal space formed by the lower housing (140) being joined to the lower portion of the upper housing (110), with a portion thereof penetrating the holder (220) of the transmitter (200).

[0153] The grip portion (172) is positioned on the upper portion of the holder (220) of the transmitter (200). The needle (171) is positioned so that, with the lower portion of the grip portion (172) positioned on the upper portion of the holder (220), the needle (171) penetrates the holder (220) from the lower portion of the grip portion (172) and passes through the lower through hole formed in the base portion (211) of the transmitter (200) and extends below the lower surface of the transmitter (200).

[0154] As shown in FIGS. 11 and 12, the needle (171) is positioned to surround at least a portion of the circumference of the proximal portion (214a) of the sensor (214) disposed in the transmitter (200) while penetrating the transmitter (200).

[0155] The driving unit (150) is placed on the upper portion of the transmitter (200) in the internal space formed by the upper housing (110) and the lower housing (140).

[0156] The driving unit (150) is configured to move the transmitter (200) and needle assembly linearly along the length direction of the applicator. The driving unit (150) includes a spring (151), a wheel (152), and a locking member (153).

[0157] The spring (151) is a power source that provides power to the needle carrier (160) to enable linear movement of the needle carrier (160) described later.

[0158] It is preferable that the spring (151) is a wound reel spring (151). The spring (151) is assembled in a compressed state in the initial state.

[0159] In order to release the compression of the spring (151), a button (120) may be provided that penetrates from the outer surface of the upper housing (110) to the inside.

[0160] When the fastener that was fixing the compression of the spring (151) by the pressure of the button (120) is released, the spring (151) can be tensioned to return to its original state, thereby causing one end of the spring (151) to rotate. That is, the principle of a kind of Scotch Yoke or double slider crank mechanism may be applied, in which the rotational motion of the spring (151) is converted into the linear motion of the needle carrier (160) and the needle assembly.

[0161] One side of the wheel (152) is connected to one end of the spring (151) and configured to rotate together with the rotation of the spring (151). A groove may be formed on the outer surface of the wheel (152) for coupling with the locking member (153).

[0162] The locking member (153) is configured such that one end is connected to the button (120) and the other end is engaged with the wheel (152). At this time, a groove is formed at the other end of the locking member (153) so that it can engage with the groove of the wheel (152). This prevents rotation of the wheel (152) and, further, prevents tension of the spring (151).

[0163] When the button (120) is pressed by the user and moves toward the inside of the applicator, the locking member (153) also moves in conjunction with it. As a result, the engagement between the other end of the locking member (153) and the groove of the wheel (152) is released, and the wheel (152) can rotate together due to tension and rotation caused by the elasticity of the spring (151).

[0164] The needle carrier (160) is configured to move linearly inside the upper housing (110) and the lower housing (140).

[0165] At this time, the linear movement of the needle carrier (160) can be induced by the rotational movement of the driving unit (150). For this purpose, it is preferable that the needle carrier (160) has an overall T-shape or cross-shape.

[0166] One side of the needle carrier (160) is coupled to the other side of the wheel (152), and the lower side is coupled to the upper part of the grip part (172) of the needle assembly, so that the linear movement of the needle assembly can be achieved according to the rotational movement of the wheel (152) according to the tension of the spring (151).

[0167] Specifically, the needle assembly and the transmitter (200) move downward together according to the triggering motion of the applicator by pressing the button (120), so that the lower surface of the transmitter (200) is attached to the user's body and fixed in a state where the needle (171) and the sensor (214) are inserted into the user's body, and then the needle carrier (160) moves upward, so that only the needle assembly is separated from the transmitter (200).

[0168] At this time, the operation of the transmitter is activated as the contact between the conductor (not shown) installed in the applicator and the activation terminal of the transmitter is released.

[0169]

[0170] 3. Other embodiments of transmitters and applicators

[0171] Next, referring to FIGS. 14 to 22, another embodiment of the transmitter (200a) and applicator according to the present invention will be described.

[0172] In the description of other embodiments below, the differences between the transmitter (200a) and the applicator described above will be explained, and descriptions of identical configurations will be omitted.

[0173] Additionally, each configuration of the transmitter (200a) and the applicator according to another embodiment may be alternatively applied to the above-described embodiment.

[0174] As shown in FIGS. 14 and 15, the transmitter (200a) of another embodiment does not include a holder.

[0175] Accordingly, the opening (228) formed in the sensor housing (227a) of the sensor assembly (210a) is not sealed by the holder, and the opening (228) is sealed by the protrusion (173) formed at the bottom of the grip portion (172a) of the needle assembly of the applicator, and further, in a state where the needle (171) is positioned to penetrate the transmitter (200), the grip portion (172a) can be stably aligned with the transmitter (200) (see FIGS. 21 and 22).

[0177] Referring to FIGS. 16 and 17, the configuration of the electrode portion (215a) and the connector (222a) of another embodiment will be described in detail.

[0178] In another embodiment, the electrode portion (215a) is located on one side of the sensor (214) on the base portion (211). The electrode portion (215a) includes a contact terminal (216a) and a connection terminal (217a).

[0179] The contact terminal (216a) does not include an external terminal and is composed of an internal terminal (218a) that is electrically connected to the sensor (214).

[0180] The contact terminal (216a) is located at the lower part of the distal part (214b) of the sensor (214), and the connection terminal (217a) is located so as to extend from the contact terminal (216a) to the other side, and the contact terminal (216a) and the connection terminal (217a) are electrically connected.

[0182] The connector (222a) includes a fixing part (225a) and a connecting pin.

[0183] The fixed part (225a) is located above the contact terminal (216a) on the base, and a mounting groove (226a) is formed in the fixed part (225a).

[0184] The connecting pin is installed in the fixed part (225a) and includes a sensor contact part (223a) and a terminal contact part (224a).

[0185] The sensor contact portion (223a) is located on one side of the connecting pin, on the side of the mounting groove (226a). The terminal contact portion (224a) extends from the sensor contact portion (223a) and is positioned to contact the contact terminal (216a).

[0186] The connecting pin is made of a conductive material and is configured to have elasticity in a curved shape, and a plurality of them can be installed on both sides centered on the mounting groove (226a).

[0187] When the connector (222a) is installed on the contact terminal (216a), the distal portion (214b) of the sensor (214) is fitted into the mounting groove (226a) at the top of the fixing portion (225a), and the sensor contact portion (223a) is pressed to contact the sensor, and after the sensor is mounted in the mounting groove (226a), the sensor contact portion (223a) presses the distal portion (214b) of the sensor (214), and the distal portion (214b) of the sensor (214) and the contact terminal (216a) are electrically connected by the connecting pin, and further, the distal portion (214b) of the sensor (214) is mechanically fixed within the mounting groove (226a).

[0188] The configuration of the sensor housing (227a) is described with reference to Fig. 18.

[0189] In another embodiment, the sensor housing (227a) does not have a conversion terminal (229a) and an activation terminal (231a) extending from the conversion terminal (229a) to the outside of the sensor housing (227a).

[0190] In another embodiment, a guide protrusion (230) is arranged inside the sensor housing (227a), and the guide protrusion (230) is arranged with a space in which the upper part of the connector (222a) can be fitted, thereby guiding the position where the connector (222a) is installed when assembling the sensor housing (227a).

[0191] Next, referring to FIGS. 19 and 20, the configuration of an electronic assembly (250a) in another embodiment will be described.

[0192] On the substrate (255) of the electronic assembly (250a), a circuit terminal and a connection electrode (254a) in contact with the circuit terminal are positioned to transmit a signal of an analyte measured by a sensor (214) or a mode conversion signal from the outside to each electronic component on the substrate (255), and are arranged at a position corresponding to the connection terminal (217a) of the base portion (211).

[0193] Additionally, the electronic assembly (250a) of another embodiment includes a conversion terminal (229a) and an activation terminal (231a).

[0195] The activation terminal (231a) extends to the other side of the conversion terminal (229a) and is exposed to the outside of the upper case (251a).

[0196] In this case, the applicator has a conductor (not shown) positioned at a position corresponding to the activation terminal (231a) located in the upper case (251a), and as in the above embodiment, the transmitter (200a) is installed in the applicator, and in a state before triggering, the conductor and the activation terminal (231a) come into contact, thereby deactivating the operation of the transmitter (200a), and when the transmitter (200a) is attached to the user's body by triggering the applicator, the contact is released and the transmitter (200a) is activated.

[0197]

[0198] 4. Assembly method of the insertion device assembly

[0199] Next, referring again to the attached drawings, a sterilization and assembly method of an insertion device assembly according to one embodiment of the present invention will be described.

[0200] First, the insertion device assembly is divided into the first assembly (ASSY 1) and the second assembly (ASSY 2) states according to the assembly order.

[0201] The first assembly (ASSY 1) includes a portion of the transmitter (200) and a portion of the applicator, and the second assembly (ASSY 2) further includes the remaining portion of the transmitter (200) and the remaining portion of the applicator from the first assembly (ASSY 1).

[0202] First, as shown in FIG. 3, FIG. 11 and FIG. 13, the first assembly (ASSY 1) is assembled.

[0203] The base part (211), electrode part (215), sensor (214), holder (220), connector (222) and sensor housing (227) of the sensor assembly (210) are assembled, and the needle assembly is assembled so that the needle (171) penetrates the holder (220) and the grip part (172) is positioned on the upper part of the holder (220), and the sensor housing (227) and the needle assembly are mounted together on the upper part of the internal space of the lower housing (140) of the applicator. The first assembly (ASSY 1) is assembled by combining the cap (130) with the lower housing (140).

[0204] In addition, as in the other embodiments described above, when the transmitter (200a) is not provided with a holder (220), the base portion (211), the electrode portion (215a), the sensor (214), the connector (222a) and the sensor housing (227a) of the sensor assembly (210a) are assembled, the needle (171) penetrates the transmitter (200a) through the opening (228) of the sensor housing (227a), and the protrusion (173) of the grip portion (172a) of the needle assembly is inserted into the opening (228) of the sensor housing (227a) and positioned at the top, thereby assembling the first assembly (ASSY 1).

[0205] Afterwards, the assembled first assembly (ASSY 1) is sterilized by irradiating the E-beam onto the first assembly (ASSY 1).

[0206] As described above, the sensor (214) and the needle (171) are directly inserted into the user's body, and the lower surface of the transmitter (200) and the lower surface of the applicator are parts that come into contact with the user's skin and thus require sterilization.

[0207] After the first assembly (ASSY 1) is sterilized, the second assembly (ASSY 2) is assembled.

[0208] A second assembly (ASSY 2) is assembled by assembling the remaining part of the transmitter (200) and the remaining part of the applicator to the first assembly (ASSY 1).

[0209] As shown in FIGS. 9, 11, 12 and 13, the second assembly (ASSY 2) assembles an electronic assembly (250) so that a substrate (255) is accommodated between an upper case (251) and a lower case (252), and the assembled electronic assembly (250) is coupled to the upper portion of the sensor assembly (210) of the first assembly (ASSY 1).

[0210] At this time, the fastening hook (213) formed on the base portion (211) of the sensor assembly (210) is caught on the catch portion (253) formed on the lower case of the electronic assembly (250), thereby forming a connection between the electronic assembly (250) and the sensor assembly (210), and after the electronic assembly (250) and the sensor assembly (210) are combined, UV bonding is formed between the inside of the outer wall (212) of the sensor assembly (210) and the lower case (252) of the electronic assembly (250).

[0211] An embodiment is described in which the lower case (252) of the electronic assembly (250) and the base part (211) of the sensor assembly (210) are hook-joined, but is not limited thereto, and the lower case (252) and the base part (211) of the sensor assembly (210) can be joined only by bonding using an adhesive.

[0212] Then, the second assembly (ASSY 2) is assembled by fitting the lower part of the needle carrier (160) into the grip part (172) of the needle assembly, connecting the driving part (150) to one side of the needle carrier (160), and covering and connecting the upper housing (110) equipped with the button (120) to the upper part of the lower housing (140).

[0213] Afterwards, a process of packaging the assembled second assembly (ASSY 2) is further included, at which time the conductor (not shown) installed in the applicator comes into contact with the activation terminal (131) of the transmitter (200).

[0214] According to one embodiment of the present invention, a transmitter holder (not shown) may be further included. The transmitter holder (not shown) may be positioned to cover the upper portion of the transmitter (200) and surround the grip portion (172). A conductor may be installed in the transmitter holder (not shown) so as to come into contact with the activation terminal (131) of the transmitter (200) when assembling the second assembly (ASSY 2).

[0215]

[0216] According to the transmitter of the present invention and the insertion device assembly including the same, the following effects can be obtained.

[0217] 1) First, by dividing the transmitter into a sensor assembly and an electronic assembly and configuring them separately, sterilization of only the sensor assembly is possible without a separate shielding device.

[0218] 2) By dividing the transmitter into a sensor assembly and an electronic assembly and configuring them separately, the sensor and needle, which are the parts directly inserted into the user's body, and the lower surface of the transmitter and the lower surface of the applicator, which come into contact with the user's skin, are modularized as the first assembly, making it possible to sterilize the parts requiring sterilization with just one E-Beam irradiation.

[0219] 3) By dividing the transmitter into a sensor assembly and an electronic assembly and configuring them separately, the electronic components that may lose some functions when directly exposed to the E-beam are mounted on the board, and the components such as the upper housing or driving part of the applicator that have little need for sterilization are practically excluded from the first assembly, so that sterilization according to the E-beam is performed, and there is no concern that the electronic devices mounted on the board will break down, and there is an advantage in that the insertion device assembly can be sterilized with only a short E-beam irradiation in a narrow area.

[0220] 4) By configuring the transmitter so that the sensor assembly and the electronic assembly can be easily connected through hooks or bonding, etc., the electronic assembly can be easily connected to the sensor assembly after sterilization of the sensor assembly, so that even if the transmitter is configured by separating the sensor assembly and the electronic assembly, the assembly and sterilization processes can be performed quickly and easily.

[0221] 5) Since the transmitter is divided into a sensor assembly and an electronic assembly, the lower surface of the transmitter is composed of two parts: a base and a lower case, so that the force applied to the substrate contained within the transmitter when triggered through the applicator is distributed and reduced.

[0222] 6) By arranging terminals and electrodes that electrically connect between the sensor assembly and the electronic assembly so that they are connected during assembly, the sensor and the substrate can be electrically connected without a separate electrical connection work at the same time as the sensor assembly and the electronic assembly are combined.

[0223] 7) By configuring the connector connecting the electrode and terminal to the sensor in the form of a clip, it is possible to electrically connect the sensor and the electrode and terminal using the connector without a separate configuration for fixing the sensor, and at the same time fix the sensor to the sensor assembly.

[0224] 8) The transmitter mode can be changed by installing a conversion terminal on the sensor housing.

[0225]

[0226] The above description is merely an illustrative illustration of the technical idea of ​​the present invention, and those skilled in the art will appreciate that various modifications and variations can be made without departing from the essential characteristics of the present invention. Therefore, the above-described embodiments are intended to illustrate, rather than limit, the technical idea of ​​the present invention, and the scope of the technical idea of ​​the present invention is not limited by these embodiments.
