Description

Technical Field

[0001] The present invention mainly relates to the field of medical devices, and in particular to an analyte detection device installation unit. Background Art

[0002] The pancreas in a normal person's body can automatically detect the glucose content in the human blood and automatically secrete the required insulin / glucagon. However, the pancreas of diabetic patients has abnormal function and cannot normally secrete the insulin required by the human body. Therefore, diabetes is a metabolic disease caused by abnormal pancreatic function in the human body, and diabetes is a lifelong disease. At present, medical technology cannot cure diabetes, and can only control the occurrence and development of diabetes and its complications by stabilizing blood sugar.

[0003] Diabetic patients need to test their blood sugar before injecting insulin into their bodies. Currently, most detection methods can continuously detect blood sugar and send blood sugar data to external devices in real time for users to view. This detection method is called continuous glucose monitoring (CGM). In order to achieve continuous glucose detection, users need to use an auxiliary mounting unit to install the blood sugar analyte detection device on the skin surface. The smaller the size of the mounting unit, the more convenient it is for users to use, and the manufacturing cost is lower. Therefore, under the premise that the function of the mounting unit can be realized, the miniaturization design of the mounting unit is beneficial. When using the mounting unit, reducing the retraction stroke of the auxiliary needle is a design idea for miniaturization of the mounting unit. After reducing the retraction stroke of the auxiliary needle, a part of the auxiliary needle will be exposed outside the shell. It is necessary to provide protection for the auxiliary needle to avoid unnecessary harm to the user.

[0004] Therefore, the prior art urgently needs a more miniaturized and safer analyte detection device installation unit. Summary of the invention

[0005] The present invention discloses an installation unit for an analyte detection device. After the installation unit is used, the through hole on the parallel slider module accommodates the needle tip of the auxiliary needle, and the parallel slider module is fixed relative to the trigger module through a fixing structure to prevent the parallel slider module from retracting into the interior of the installation unit housing. The parallel slider module can provide effective safety protection for the auxiliary needle without adding additional structural parts, and is also conducive to the miniaturized design of the installation unit.

[0006] The present invention provides an analyte detection device installation unit, comprising: a shell and an elastic module, a trigger module, a parallel slider module, an auxiliary needle module and an analyte detection device pre-installed in the shell; the parallel slider module carries the auxiliary needle module and the analyte detection device, the auxiliary needle module includes an auxiliary needle, the parallel slider module includes a through hole and a fixing structure, and the auxiliary needle passes through the through hole; when the installation unit is used, the shell abuts the skin surface, the elastic module pushes the parallel slider module to slide proximally until it abuts the skin surface, and at the same time the elastic module pushes the auxiliary needle module to slide, so that the auxiliary needle retracts after piercing the subcutaneous tissue; after the installation unit is used, at least a portion of the auxiliary needle is exposed outside the shell, the through hole accommodates the needle tip of the auxiliary needle, and the parallel slider module is fixedly connected relative to the trigger module through the fixing structure.

[0007] According to one aspect of the present invention, after the auxiliary needle is retracted, the parallel slider module no longer slides, and the through hole accommodates the needle tip of the auxiliary needle.

[0008] According to one aspect of the present invention, after the auxiliary needle is retracted, the mounting unit is removed, and the elastic module pushes the parallel slider module to continue sliding toward the proximal end until the needle tip of the auxiliary needle is accommodated in the through hole.

[0079] In the embodiment of the present invention, the slider buckle 10321 is made of a flexible material and can be bent or folded toward the outside of the circular groove 1032 .

[0080] In other embodiments of the present invention, the slider buckle 10321 can be directly disposed on the distal end surface of the parallel slider module 103 without the need for a circular groove structure.

[0081] In the embodiment of the present invention, a boss 10322 is further provided at one end of the circular groove 1032 near the distal end surface 1031.

[0090] Analyte detection device

[0091] Figure 6 Schematic diagram of the structure of the analyte detection device according to an embodiment of the present invention.

[0092] Combined with reference Figure 3In the embodiment of the present invention, the analyte detection device 104 includes a housing 1041, a transmitter (not shown in the figure), a sensor 1042, and an internal circuit (not shown in the figure) disposed in the housing 1041 and electrically coupled to the sensor. The sensor 1042 is used to detect the analyte parameter information of the user's body fluid, and transmit the analyte parameter information to the transmitter through the internal circuit, and then the transmitter sends it to the external device 200.

[0093] In a preferred embodiment of the present invention, before the analyte detection device 104 is installed on the user's skin surface, a signal is transmitted to the external device 200 at a first frequency f1, and after being installed on the user's skin surface, a signal is transmitted to the external device 200 at a second frequency f2, and the second frequency f2 is greater than the first frequency f1. In a further preferred embodiment of the present invention, the first frequency f1 is 0 to 12 times / hour, and the second frequency f2 is 12 to 3600 times / hour.

[0094] In a more preferred embodiment of the present invention, the first frequency f1 is 0 times / hour, that is, before the analyte detection device 104 is installed on the user's skin surface, no signal is transmitted to the external device 200, which can save power consumption of the analyte detection device 104 before installation.

[0095] In an embodiment of the present invention, the housing 1041 includes an upper housing body 10411 and a lower housing body 10413, and the upper housing body 10411 and the lower housing body 10413 are spliced ​​to form an internal space. The sensor 1042 includes an external part (not shown in the figure) and an internal part (not shown in the figure), and the external part, a transmitter and an internal circuit are arranged in the internal space, and the external part is electrically coupled with the internal circuit. The internal part is provided with structures such as electrodes and a membrane layer, and piercing the subcutaneous part of the user can detect the analyte parameter information. When the internal part pierces the subcutaneous part, it needs to have a correct angle, for example, piercing perpendicular to the skin surface. After the life of the analyte detection device 104 ends, it is removed from the user's skin surface and discarded as a whole.

[0096] In an embodiment of the present invention, the lower outer shell 10413 includes a first through hole 10414 extending therethrough. Correspondingly, on the axis of the first through hole 10414, the upper outer shell 10411 includes a second through hole (not shown in the figure) extending therethrough. The internal part passes through the first through hole 10414 to the outside of the outer shell to facilitate penetration into the user's subcutaneous tissue.

[0097] In the embodiment of the present invention, the side of the upper outer shell 10411 includes a snap hole 10412 corresponding to the T-shaped structure buckle 10352, where "corresponding" means that the position and number of the snap hole 10412 are consistent with the T-shaped structure buckle 10352. In the installation unit 100, the upper outer shell 10411 is fitted with the proximal surface 1034, the T-shaped structure buckle 10352 and the snap hole 10412 form a snap connection, and the analyte detection device 104 is fixed on the parallel slider module 103. When the horizontal portion of the T-shaped structure is bent or curved around the vertical portion, the snap connection between the T-shaped structure buckle 10352 and the snap hole 10412 is released, and the analyte detection device 104 is separated from the parallel slider module 103. Therefore, in the installation unit 100, the analyte detection device 104 and the parallel slider module 103 are releasably connected.

[0098] Auxiliary needle module

[0099] Figure 7 Schematic diagram of the structure of the auxiliary needle module according to an embodiment of the present invention.

[0100] In the embodiment of the present invention, the auxiliary needle module 105 includes an auxiliary needle fixing structure 1051 and an auxiliary needle 1052. In the mounting unit 100, the auxiliary needle fixing structure 1051 is located at the distal end, and the auxiliary needle 1052 is located at the proximal end.

[0101] In the embodiment of the present invention, the auxiliary needle fixing structure 1051 includes an auxiliary needle slider 10511 and an auxiliary needle fixing block 10512. The diameter or width of the auxiliary needle slider 10511 is greater than the diameter or width of the auxiliary needle fixing block 10512, forming a convex surface 10513 facing the proximal end.

[0102] In the embodiment of the present invention, the auxiliary needle 1052 includes a fully enclosed needle body 10521 and a semi-enclosed needle body 10522. The fully enclosed needle body 10521 is located between the auxiliary needle fixing block 10512 and the semi-enclosed needle body 10522, and is fixedly connected to the auxiliary needle fixing block 10512. The hollow structure of the semi-enclosed needle body 10522 can be used to accommodate the internal part of the sensor 1042. When the semi-enclosed needle body 10522 is inserted into the subcutaneous tissue of the user, the internal part can be inserted into the subcutaneous tissue together, and when the needle body is retracted, the state of the internal part under the skin is not affected.

[0103] In other embodiments of the present invention, the auxiliary needle 1052 only includes a semi-enclosed needle body 10522, that is, the semi-enclosed needle body 10522 is fixedly connected to the auxiliary needle fixing block 10512. This can reduce the material used for the auxiliary needle 1052 and save costs, but it also reduces the rigidity of the auxiliary needle 1052.

[0104] In the mounting unit 100 , the auxiliary needle 1052 passes through the second through hole and the first through hole 10414 in sequence, thereby penetrating the analyte detection device 104 , and the internal part of the sensor 1042 is located in the semi-enclosed needle body 10522 .

[0105] Trigger Module

[0106] Figure 8 It is a schematic diagram of the structure of a trigger module according to an embodiment of the present invention.

[0107] In the embodiment of the present invention, at least two fixed buckles 1061 corresponding to the first buckle 1012 are provided on the trigger module 106. In the mounting unit 100, the fixed buckle 1061 contacts the first buckle 1012 to prevent the first buckle 1012 from bending or folding toward the outside of the shell. The contact between the fixed buckle 1061 and the first buckle 1012 can be point contact, line contact or surface contact. When the contact is surface contact, the contact surface between the fixed buckle 1061 and the first buckle 1012 is at a fixed angle to the horizontal plane and converges at the proximal end of the mounting unit 100. The number and position of the fixed buckle 1061 are consistent with the first buckle 1012.

[0108] In the embodiment of the present invention, at least two ears 1062 are further provided on the trigger module 106. In the installation unit 100, the ears 1062 are snap-fitted with the slots 1014 to fix the trigger module 106. The number and position of the ears 1062 are consistent with the slots 1014. Fig.10a Before the installation unit 100 is used, the ear 1062 is located at the first slot 10141 , and at this time, the fixing buckle 1061 is in contact with the first buckle 1012 .

[0109] In the embodiment of the present invention, the trigger module 106 further includes an outer ring 1063, and the outer ring 1063 connects the fixing buckle 1061 and the ear 1062 into a whole. In the installation unit 100, the outer ring 1063 is closer to the proximal end relative to the ear 1062, is located at the first opening and protrudes from the first opening, and when the installation unit 100 is used, the outer ring 1063 fits the user's skin surface.

[0110] Elastic modules

[0111] Reference Figure 3 The elastic module 107 includes a first elastic member 1071 and a second elastic member 1072 .

[0112] In an embodiment of the present invention, the first elastic member 1071 is located between the parallel slider module 103 and the shell 101, that is, one end of the first elastic member 1071 is located on the distal end surface of the parallel slider module 103, and the other end is located inside the shell 101. In the installation unit 100, the first elastic member 1071 is in a compressed state and can provide elastic force.

[0113] In an embodiment of the present invention, the second elastic member 1072 is located between the parallel slider module 103 and the auxiliary needle module 105, that is, one end of the second elastic member 1072 is located on the boss 10322 of the parallel slider module 103, and the other end is located on the convex surface 10513 of the auxiliary needle module 105. In the installation unit 100, the second elastic member 1072 is in a compressed state and can provide elastic force.

[0114] In a preferred embodiment of the present invention, the first elastic member 1071 or the second elastic member 1072 is a metal spring.

[0115] In an embodiment of the present invention, the inner ring diameter of the first elastic member 1071 is larger than the outer ring diameter of the circular groove 1032 and the auxiliary needle slider 10511. In the installation unit 100, the first elastic member 1071 is surrounded by the outside of the auxiliary needle slider 10511 and the circular groove 1032, so that the internal space of the installation unit 100 can be fully utilized.

[0116] In an embodiment of the present invention, the outer ring diameter of the second elastic member 1072 is larger than the outer diameter of the auxiliary needle fixing block 10512 and the inner diameter of the boss 10322, but smaller than the outer diameter of the auxiliary needle slider 10511 and the inner diameter of the circular groove 1032. Therefore, one end of the second elastic member 1072 is placed in the circular groove 1032, and the other end is surrounded by the outside of the auxiliary needle fixing block 10512, so that the internal space of the installation unit 100 can be fully utilized.

[0117] How to use the installation unit

[0118] Fig. 9 It is a top view of the installation unit according to an embodiment of the present invention.

[0119] Fig.10a for Fig. 9 A schematic diagram of the cross-section structure; Fig.10b for Fig. 9 Schematic diagram of the B-section structure; Fig.10c for Fig. 9 Schematic diagram of the C-section structure; Fig.11 Schematic diagram of the first buckle bending under force.

[0120] Combined with reference Fig.10a and Fig.10bIn the embodiment of the present invention, the card slot 1014 is provided with two card slot positions, a first card slot position 10141 and a second card slot position 10142. Before the installation unit 100 is used, the trigger module 106 is fixed to the housing 101 through the snap fit of the card ear 1062 and the first card slot position 10141. At this time, the fixed buckle 1061 contacts the first buckle 1012 to prevent the first buckle 1012 from bending or folding to the outside of the housing 101. The fixed buckle 1061, the first buckle 1012 and the second buckle 1033 are located on the same horizontal line. In the preferred embodiment of the present invention, from the inside to the outside of the housing 101, the second buckle 1033, the first buckle 1012 and the fixed buckle 1061 are arranged in sequence.

[0121] In an embodiment of the present invention, the contact between the fixing buckle 1061 and the first buckle 1012 is point contact, line contact or surface contact. When the above contact is surface contact, the extension line m1 of the contact surface converges at the proximal end. This structural design allows the fixing buckle 1061 to slide toward the distal end relative to the first buckle 1012.

[0122] In a preferred embodiment of the present invention, the coupling surface between the second buckle 1033 and the first buckle 1012 is a plane, which forms a fixed angle with the horizontal plane, and the extended ends m2 thereof converge at the proximal end.

[0123] Combined with reference Fig.11 This structural design allows the first buckle 1012 to be pushed toward the outside of the shell 101 when the second buckle 1033 slides toward the proximal end relative to the first buckle 1012, thereby releasing the coupling state between the first buckle 1012 and the second buckle 1033.

[0124] In an embodiment of the present invention, the first elastic member 1071 is in a compressed state and has elastic potential energy. Its own elastic force gives the parallel module slider 103 a thrust Fr toward the proximal end. The thrust Fr acts on the first buckle 1012 through the coupling surface of the second buckle 1033 and the first buckle 1012, and generates a component force Fsin perpendicular to the plane of the first buckle 1012. The component force Fsin can push the first buckle 1012 toward the outside of the shell 101 to bend or fold, thereby releasing the coupling state between the first buckle 1012 and the second buckle 1033.

[0125] In the embodiment of the present invention, when using the installation unit 100, the outer cover body 1021 is rotated to break the column 10211, and the protective cover 102 is separated from the shell 101. The proximal end of the installation unit 100 is brought close to the user's skin until the outer ring 1063 of the trigger module 106 is attached to the skin surface. The user presses the shell 101 at the distal end, and the shell 101 slides toward the skin. The trigger module 106 remains stationary, so the trigger module 106 slides distally relative to the shell 101, and the ear 1062 disengages from the first card slot 10141 and enters the second card slot 10142. At the same time, the fixed buckle 1061 is no longer in contact with the first buckle 1012. The first buckle 1012 is bent or folded toward the outside of the shell 101 due to the component force Fsin, and the coupling state between the first buckle 1012 and the second buckle 1033 is released.

[0126] In the embodiment of the present invention, after the coupling state is released, the parallel slider module 103 continues to slide toward the proximal end under the elastic force of the first elastic member 1071, while driving the analyte detection device 104 to slide toward the proximal end until the lower outer shell 10413 of the analyte detection device 104 contacts the user's skin surface.

[0127] Reference Fig.10c In the embodiment of the present invention, the slider buckle 10321 is buckled and connected with the auxiliary needle slider 10511. When the first elastic member 1071 pushes the parallel slider module 103 to slide toward the proximal end, it drives the auxiliary needle module 105 to slide toward the proximal end together.

[0128] In the embodiment of the present invention, the connection between the slider buckle 10321 and the auxiliary needle slider 10511 is a plane or a nearly plane, which is at a fixed angle to the horizontal plane, and its extension line m3 converges at the far end. The thrust of the second elastic member 1072 on the auxiliary needle slider 10511 is toward the far end, so the auxiliary needle slider 10511 can push the slider buckle 10321 to the outside of the housing 101, causing the slider buckle 10321 to bend or bend, which is equivalent to the principle of Fig.11 .

[0129] In the embodiment of the present invention, in the installation unit 100, the side wall of the auxiliary needle limiting groove 1015 prevents the slider buckle 10321 from bending or curving, and the buckled connection state between the slider buckle 10321 and the auxiliary needle slider 10511 does not change. As the parallel slider module 103 and the auxiliary needle module 105 slide toward the proximal end, until the slider buckle 10321 disengages from the auxiliary needle limiting groove 1015, the inner wall of the auxiliary needle limiting groove 1015 no longer prevents the slider buckle 10321 from bending or curving, and the second elastic member 1072 pushes the auxiliary needle slider 10511 toward the distal end, and at the same time, the auxiliary needle slider 10511 pushes the slider buckle 10321 to bend or curve outward, and the buckle connection between the slider buckle 10321 and the auxiliary needle slider 10511 is released, and the second elastic member 1072 continues to push the auxiliary needle slider 10511 to slide toward the distal end, and finally the auxiliary needle module 105 returns to the initial position, and the auxiliary needle 1052 retracts into the shell 101 to prevent the auxiliary needle 1052 from being exposed outside the shell 101 to avoid unnecessary damage.

[0130] In the embodiment of the present invention, when the slider buckle 10321 is disengaged from the auxiliary needle limiting groove 1015, the semi-enclosed needle body 10522 of the auxiliary needle penetrates into the subcutaneous tissue of the user.

[0131] In an embodiment of the present invention, in the installation unit 100, the T-shaped structure slider 10351 is located in the limiting groove 1013, and the limiting groove 1013 limits the position and direction of the parallel slider module 103 through the T-shaped structure slider 10351 to ensure that the parallel slider module 103 remains perpendicular to its sliding direction, so that the analyte detection device 104 arranged at the front end of the parallel slider module 103 remains perpendicular to its sliding direction, and the auxiliary needle 1052 remains parallel to its sliding direction, so that the auxiliary needle 1052 and the part of the sensor body it envelops can be inserted into the user's subcutaneous tissue at a vertical angle, thereby reducing the user's pain.

[0132] In an embodiment of the present invention, during the sliding of the parallel slider module 103 toward the proximal end, the T-shaped structure slider 10351 slides in the limiting groove 1013 until it contacts the outer ring 1063 of the trigger module 106. Pushed by the first elastic member 1071, the parallel slider module 103 continues to slide toward the proximal end, while the outer ring 1063 blocks the T-shaped structure slider 10351 from continuing to slide toward the proximal end. Therefore, the T-shaped structure slider 10351 bends or folds around the vertical portion, and the buckle connection between the T-shaped structure buckle 10352 and the buckle hole 10412 is released, and the analyte detection device 104 is detached from the parallel slider module 103 so that it can be installed on the user's skin surface.

[0133] In the embodiment of the present invention, when the T-shaped structure slider 10351 contacts the outer ring 1063, the position of the parallel slider module 103 is the predetermined position. At this time, the lower outer shell 10413 of the analyte detection device contacts the user's skin surface.

[0134] In the embodiment of the present invention, the auxiliary needle 1052 passes through the second through hole and the first through hole 10414 in sequence, and penetrates the analyte detection device 104, and at the same time, the semi-enclosed needle body 10522 of the auxiliary needle envelops the sensor 1042. During the sliding process of the parallel slider module 103 and the auxiliary needle module 105 toward the proximal end, the semi-enclosed needle body 10522 carries the sensor 1042 and penetrates the subcutaneous tissue. After the auxiliary needle 1052 is retracted, the internal part of the sensor 1042 remains under the skin, and the state of the internal part of the sensor 1042 is not affected when the needle body is retracted.

[0135] In the embodiment of the present invention, when performing the installation action, the user is required to press the housing 101 at the distal end, apply a proximal force F to the housing 101, and the outer ring 1063 of the trigger module 106 contacts the user's skin surface. The user's skin applies a force F' to the outer ring 1063 in the opposite direction of the force F, thereby achieving relative sliding of the trigger module 106 and the housing 101. During the actual installation process, the absolute position of the trigger module 106 remains unchanged, and the housing 101 slides toward the proximal end.

[0136] Before the installation is performed, in order to prevent the trigger module 106 from sliding relative to the shell 101, a protective cover 102 is installed at the proximal end of the shell 101. The protective cover 102 surrounds the outside of the outer ring 1063 of the trigger module, which can prevent the installation from being performed in an incorrect position due to accidental contact with the outer ring 1063, thereby playing an anti-trigger role.

[0137] The distal surface 10232 of the inner cover body 1023 contacts the analyte detection device 104, and the auxiliary needle 1052 and the sensor 1042 extend into the inner cover body groove 10233, which can play a sealing role to prevent external dust, particles and other dirt from contacting the needle body and the sensor and causing contamination.

[0138] In the embodiment of the present invention, an adhesive tape (not shown in the figure) is further provided on the lower outer shell 10413 of the analyte detection device to fix the analyte detection device 104 on the user's skin surface.

[0139] Second embodiment

[0140] In the aforementioned embodiment, after the user uses the installation unit, the auxiliary needle automatically retracts into the shell under the action of the second elastic member to avoid the auxiliary needle causing unnecessary harm to the user. The auxiliary needle is fully retracted into the shell, and sufficient height needs to be reserved in the shell to accommodate the auxiliary needle module, which limits the miniaturization design of the installation unit. In order to further reduce the overall height of the shell of the installation unit and reduce the volume of the installation unit, the embodiment of the present invention considers reducing the retraction stroke of the auxiliary needle. After the retraction stroke of the auxiliary needle is reduced, the needle tip of the auxiliary needle may be exposed outside the shell of the installation unit, which is unsafe for the user. Therefore, it is also necessary to consider protection measures for the auxiliary needle and design a needle body protection structure for the auxiliary needle.

[0141] Under the above technical background, in some embodiments of the present invention, after the user uses the installation unit to install the analyte monitoring device, the auxiliary needle is not completely retracted into the shell, and at least a portion of the auxiliary needle, such as the needle tip, is exposed outside the shell. The user assembles the needle protection structure onto the installation unit to protect the exposed needle tip. The specific implementation of the needle protection structure will be described in detail below.

[0142] In the embodiments of the present invention, technical solutions not described are deemed to be the same as those in the aforementioned embodiments and will not be described in detail herein.

[0143] Fig.12 It is a schematic diagram of the explosion structure of the installation unit of the analyte detection device according to an embodiment of the present invention. Fig.13a It is a schematic diagram of the separation structure of the outer cover body and the inner cover body according to an embodiment of the present invention. Fig.13b It is a schematic diagram of the integrated structure of the outer cover body and the inner cover body according to an embodiment of the present invention. Fig.13c Schematic diagram of the structure of the outer cover body according to an embodiment of the present invention.

[0144] Reference Fig.12 In some embodiments of the present invention, the installation unit 200 includes a housing 201 and a protective cover 202. As described above, before installation, the analyte detection device 204 is pre-installed inside the housing 201. During installation, the elastic module (not shown in the figure, refer to Fig.17 ) is pushed toward the proximal end and installed on the user's skin surface. The protective cover 202 is arranged at the proximal end of the housing 201 and is releasably connected to the housing 201 to protect the various structural components inside the housing 201 before installation.

[0145] Combined with reference Figure 13a to Figure 13c In some embodiments of the present invention, the protective cover 202 includes an outer cover body 2021, an inner cover body 2023 and a label paper 2024. According to the relative position relationship shown in Figure 13, before installation, the inner cover body 2023 is accommodated in the outer cover body cavity 20214, and the label paper 2024 is used to seal the outer cover body cavity 20214 to seal the inner cover body 2023 in the outer cover body cavity 20214.

[0146] In some embodiments of the present invention, the inner cover 2023 is in a movable state or a releasable connection state relative to the outer cover 2021. When the inner cover 2023 is in a movable state relative to the outer cover 2021, the outer cover 2021 has no constraint structure on the inner cover 2023 to limit the state of the inner cover 2023 in the outer cover 2021. When necessary, the user can directly remove the inner cover 2023 from the outer cover 2021. When the inner cover 2023 is in a releasable connection state relative to the outer cover 2021, the inner cover 2023 and the outer cover 2021 are fixed together by buckles, hooks, threads, Velcro, etc. When necessary, the user needs to first release the fixed connection between the inner cover 2023 and the outer cover 2021, and then remove the inner cover 2023 from the outer cover 2021 after the inner cover 2023 and the outer cover 2021 are separated. In a preferred embodiment of the present invention, in order to facilitate user use, before using the installation unit 200, the inner cover body 2023 is in a movable state relative to the outer cover body 2021, so that the user can remove the inner cover body 2023 from the outer cover body 2021 when using the installation unit 200.

[0147] In some embodiments of the present invention, in order to accommodate the inner cover body 2023 in the outer cover body 2021, the middle part of the outer cover body 2021 protrudes toward the distal end and forms an outer cover body cavity 20214 with a proximal opening. The inner diameter of the outer cover body cavity 20214 is slightly larger than the outer diameter of the inner cover body 2023. For example, a gap of 0.5 to 5 mm is left between the inner wall of the outer cover body cavity 20214 and the outer wall of the inner cover body 2023. At the same time, the depth of the outer cover body cavity 20214 is not less than the height of the inner cover body 2023 to prevent the inner cover body 2023 from protruding out of the outer cover body cavity 20214, so as to facilitate the label paper 2024 to be pasted on the proximal surface 20215 of the outer cover body 2021, thereby completing the sealing of the outer cover body cavity 20214.

[0148] In some embodiments of the present invention, a plurality of raised semicircular balls 20234 are further provided on the proximal surface 20232 of the inner cover 2023. Before using the mounting unit 200, the inner cover 2023 is accommodated in the outer cover cavity 20214, and the label paper 2024 is pasted on the proximal surface 20215 of the outer cover 2021. The pasting coating area of ​​the label paper 2024 may exceed the contact area between the label paper 2024 and the outer cover 2021, causing the pasting coating of the label paper 2024 to contact the proximal surface 20232 of the inner cover 2023, and the inner cover 2023 and the label paper 2024 are pasted. When removing the inner cover 2023, it is difficult for the user to tear off the label paper 2024, and the label paper 2024 may even be damaged when being torn off, and adhere to the inner cover 2023, affecting the user's use experience. Based on this, a plurality of raised semi-circular balls 20234 are arranged on the proximal surface 20232 of the inner cover body 2023, which are in contact with the label paper 2024, thereby reducing the contact area between the proximal surface 20232 of the inner cover body 2023 and the label paper 2024, and preventing the label paper 2024 from adhering to the proximal surface 20232 of the inner cover body 2023 over a large area, making it convenient for users to tear off the label paper 2024.

[0149] In some embodiments of the present invention, the number of the raised semicircular balls 20234 is at least 2, which are symmetrically or asymmetrically distributed on the proximal surface of the inner cover body 2023. Preferably, the raised semicircular balls 20234 are symmetrically and evenly distributed on the proximal surface of the inner cover body 2023.

[0150] In some embodiments of the present invention, information related to the analyte detection device 204, the installation unit 200 and other equipment may be printed on the label paper 2024, such as production batch number, production date, instructions for use, communication connection SN code, trademark, QR code, etc.

[0151] In some embodiments of the present invention, before using the mounting unit 200, the protective cover 202 and the housing 201 can be releasably connected. The specific use method has been described in the first embodiment and will not be repeated here. When the protective cover 202 is installed on the housing 201, the needle body accommodating cavity 20213 on the outer cover 2021 can accommodate the auxiliary needle 2052. The needle body accommodating cavity 20213 is an opening toward the distal end ( Fig.13a The needle body accommodating cavity 20213 may be a hollow cone or a cone with a visible distal opening. When the needle body accommodating cavity 20213 is a conical structure, its diameter gradually decreases from the distal end to the proximal end. The interior of the needle body accommodating cavity 20213 may be a hollow structure parallel to the external structure, or may be a hollow structure whose inner diameter decreases from the distal end to the proximal end. The auxiliary needle 2052 shares a central axis with the needle body accommodating cavity 20213, so that the auxiliary needle 2052 can enter the hollow cavity from the distal opening of the needle body accommodating cavity 20213. While the needle body accommodating cavity 20213 protects the auxiliary needle 2052, it effectively utilizes the internal space of the shell 201, and the structure is more compact.

[0152] Fig.14 This is a schematic diagram of the state of the installation unit after use according to an embodiment of the present invention.

[0153] Reference Fig.14 In some embodiments of the present invention, the user places the mounting unit 200 on the skin surface, the trigger module 206 contacts the skin, the user applies pressure to the mounting unit 200 from the distal end to the proximal end, the housing 201 slides proximally relative to the trigger module 206, and in the process of the housing 201 sliding proximally relative to the trigger module 206, the trigger module 206 releases the restriction of the elastic module (not shown in the figure), and under the elastic force of the elastic module, the parallel slider module 203, the analyte detection device 204 and the auxiliary needle 2052 are pushed to slide proximally together until the analyte detection device 204 contacts the skin surface and the auxiliary needle 2052 penetrates into the subcutaneous tissue.

[0154] Reference Fig.14 In the direction shown, in some embodiments of the present invention, during the process of the parallel slider module 203, the analyte detection device 204 and the auxiliary needle 2052 sliding toward the proximal end together, when the proximal end surface of the analyte detection device 204 is flush with the proximal end surface of the trigger module 206, the parallel slider module 203 is in the third predetermined position, and the adhesive tape (not shown in the figure) at the proximal end of the analyte detection device 204 contacts the user's skin surface, and the elastic module still has a proximal thrust for the parallel slider module 203. The parallel slider module 203 carries the analyte detection device 204 and the auxiliary needle 2052 and continues to slide toward the proximal end relative to the housing 201, and the analyte detection device 204 at the proximal end of the parallel slider module 203 presses the skin surface. The analyte detection device 204 presses the adhesive tape on the skin surface, which can increase the adhesive effect between the adhesive tape and the skin surface, so that the analyte detection device 204 can be more firmly attached to the skin surface.

[0155] In some embodiments of the present invention, when the parallel slider module 203 continues to slide proximally relative to the shell 201, the position of the parallel slider module 203 no longer changes due to the obstruction of the skin surface. If the elastic member in the elastic module still has elastic force that has not been completely released, the elastic module pushes the shell 201 to slide distally relative to the parallel slider module 203, and carries the trigger module 206 away from the skin surface until the proximal surface of the trigger module 206 forms a height difference h1 with the proximal surface of the parallel slider module 203. At this time, the parallel slider module 203 is located at the first predetermined position, and a pit is formed on the skin surface under the extrusion of the analyte detection device 204 and the parallel slider module 203.

[0156] In some embodiments of the present invention, as the parallel slider module 203 continues to slide proximally relative to the shell 201, the snap connection between the parallel slider module 203 and the analyte detection device 204 is decoupled, and when the relative sliding of the parallel slider module 203 and the shell 201 is terminated, the parallel slider module 203 has been separated from the analyte detection device 204, while the parallel slider module 203 is still confined in the shell 201. At this time, the analyte detection device 204 is in a separated state relative to the shell 201, and the user can lift the shell 201 toward the distal end by hand, and the analyte detection device 204 is adhered to the skin surface with tape.

[0157] In some embodiments of the present invention, when the parallel slider module 203 slides proximally to the first predetermined position relative to the housing 201, the auxiliary needle module 205 slides proximally to the end relative to the housing, at which time the auxiliary needle 2052 penetrates the subcutaneous tissue, and the internal part of the sensor 2042 is delivered to the subcutaneous predetermined depth. Subsequently, the auxiliary needle module 205 retracts and slides distally to the second predetermined position relative to the housing 201.

[0158] Fig.15 This is a schematic diagram of the state of the auxiliary needle of the mounting unit after retraction according to an embodiment of the present invention.

[0159] Reference Fig.15 In some embodiments of the present invention, after the auxiliary needle module 205 slides distally to a second predetermined position, that is, the end point of retraction, the auxiliary needle 2052 withdraws from the subcutaneous tissue, making it easier for the user to remove the housing 201. After the auxiliary needle 2052 is retracted, the in vivo portion of the sensor 2042 remains under the skin.

[0160] In some embodiments of the present invention, after the auxiliary needle 2052 is retracted, when the auxiliary needle module 205 is in the second predetermined position, a portion of the needle tip of the auxiliary needle 2052 is exposed outside the housing 201, such as Fig.15 As shown, a height difference h2 is formed between the needle tip of the auxiliary needle 2052 and the proximal end surface of the parallel slider module 203, that is, the length of the auxiliary needle 2052 exposed outside the housing 201 is h2, and the range of h2 is 0.1-5 mm. If the exposed length of the auxiliary needle 2052 is too long, the needle tip will be retained under the skin when retracted, which may cause damage to the skin or body when the user removes the housing 201.

[0161] In some embodiments of the present invention, after the auxiliary needle 2052 is retracted, a portion of the needle tip is exposed outside the housing 201, rather than being completely retracted into the housing 201, which can reduce the retraction stroke of the auxiliary needle 2052, thereby reducing the overall height of the housing 201, making the installation unit 200 more compact and lighter in weight, while also reducing the material usage of the housing 201 and reducing the production cost of the installation unit 200. Fig.15In the figure, the dotted line represents the auxiliary needle module 205 before and after the retraction stroke is reduced, and the final position of the auxiliary needle module 205 after retraction. The final position of the auxiliary needle module 205 before the retraction stroke is reduced is near the distal end, and the final position of the auxiliary needle module 205 after the retraction stroke is reduced is near the proximal end.

[0162] In some embodiments of the present invention, the reduction of the retraction stroke of the auxiliary needle 2052 means that the auxiliary needle module 205 reduces the same retraction stroke. Fig.15 , the reduced retraction stroke of the auxiliary needle module 205 is h3. After the auxiliary needle module 205 reduces the retraction stroke, the overall height of the shell 201 can be reduced. The reduced overall height of the shell 201 can be consistent with the reduced retraction stroke of the auxiliary needle module 205, both of which are h3.

[0163] In some embodiments of the present invention, the auxiliary needle 2052 is exposed outside the housing 201, and the needle tip may cause unnecessary harm to the human body. Therefore, after using the installation unit 200, a needle body protection structure is required to protect the exposed needle tip.

[0164] Figures 16a to 16c Schematic diagram of the inner cover body used as a needle body protection structure in an embodiment of the present invention.

[0165] Combined with reference Figures 16a to 16c and Fig.13c In some embodiments of the present invention, after using the installation unit 200, the user can remove the inner cover body 2023 from the outer cover body 2021, and the inner cover body 2023 can be assembled to the parallel slider module 203, the trigger module 206 or the outer shell 201. The inner cover body 2023 is provided with a needle protection cavity 20233, which can be used to protect the exposed needle tip of the auxiliary needle 2052.

[0166] In some embodiments of the present invention, the inner cover 2023 and the parallel slider module 203 are assembled as an embodiment for description, and the inner cover 2023 is a needle protection structure of the embodiment of the present invention. The proximal surface of the parallel slider module 203 is larger than the proximal surface of the trigger module 206 or the housing 201, and is easier to process and assemble.

[0167] In some embodiments of the present invention, reference Fig.16b In the direction shown, the needle protection cavity 20233 is a hollow cavity opening toward the distal end, and the hollow cavity inside it can be used to accommodate the exposed needle tip of the auxiliary needle 2052. The outer side of the needle protection cavity 20233 can be a cylinder, a cone, a cuboid or other irregular three-dimensional structure, which is not limited here, and the inner cavity can be a structure of the same or different shape as the outer side. Preferably, the inner cavity is a cylinder or a cone, and more preferably, the inner cavity is a cone, and its inner diameter gradually decreases from the distal end to the proximal end.

[0168] In some embodiments of the present invention, if the auxiliary needle 20522 is in an eccentric position relative to the parallel slider module 203, the needle protection cavity 20233 is also in an eccentric position on the inner cover 2023, that is, the auxiliary needle 20522 and the needle protection cavity 20233 share a central axis. Before assembling the outer cover 2021 to the parallel slider module 203, the user needs to ensure that the distal opening of the needle protection cavity 20233 is aligned with the auxiliary needle 20522 to avoid misalignment of the needle protection cavity 20233 and the auxiliary needle 20522.

[0169] In some embodiments of the present invention, the inner cover 2023 and the parallel slider module 203 are assembled and connected by one or more of buckles, hooks, blocks, threads, bolts, Velcro, glue, etc., and any assembly method that can assemble the inner cover 2023 to the parallel slider module 203 should be included in the protection scope of the present invention. At least two structures for assembly connection are provided at corresponding positions of the inner cover 2023 and the parallel slider module 203, and preferably, the assembly structures are symmetrically distributed on the inner cover 2023 and the parallel slider module 203.

[0170] In some embodiments of the present invention, the assembly structure can be interchanged between the inner cover 2023 and the parallel slider module 203. For example, a hook 20231 is provided on the distal surface of the inner cover 2023, and a corresponding hole 2037 is provided on the proximal surface of the parallel slider module 203, for establishing an assembly connection with the hook 20231. In other embodiments of the present invention, the hook 20231 can be provided on the parallel slider module 203, and the corresponding hole 2037 is provided on the inner cover 2023.

[0171] In some embodiments of the present invention, in order to facilitate the user to assemble the inner cover 2023 and increase the assembly firmness of the inner cover 2023, a positioning structure is also provided on the inner cover 2023 and the parallel slider module 203. The positioning structure is composed of a positioning column 20232 and a positioning hole 2036, and the position and quantity on the inner cover 2023 and the parallel slider module 203 correspond.

[0172] In some embodiments of the present invention, the positioning post 20232 may be located at the distal end surface of the inner cover 2023, and the positioning hole 2036 may be located at the proximal end surface of the parallel slider module 203. In other embodiments of the present invention, the positioning hole 2036 may be located at the distal end surface of the inner cover 2023, and the positioning post 20232 may be located at the proximal end surface of the parallel slider module 203.

[0173] In some embodiments of the present invention, the positioning structure is not limited to Figure 16a to Figure 16cThe combination of the positioning column 20232 and the positioning hole 2036 shown can also be other types of positioning structures, such as a combination of a slider and a slide groove. All structures involving the positioning function should be included in the protection scope of the present invention.

[0174] In some embodiments of the present invention, the user holds the inner cover 2023 and the housing 201 by hand and brings them close to each other, aligns the assembly structure and the positioning structure, and then places the auxiliary needle 20522 on the central axis of the needle body protection cavity 20233, and then presses the inner cover 2023 and the housing 201 hard to assemble the inner cover 2023 onto the parallel slider module 203. The needle body protection cavity 20233 wraps the auxiliary needle 20522 to seal and protect the exposed needle tip. The schematic diagram of the state where the inner cover 2023 is assembled to the parallel slider module 203 is shown in FIG. Fig.16c shown.

[0175] Fig.17 It is a schematic cross-sectional structure diagram of the installation unit according to an embodiment of the present invention.

[0176] Reference Fig.17 In some embodiments of the present invention, the elastic module includes a first elastic member 2071, a second elastic member 2072 and a third elastic member 2073. Before using the mounting unit 200, the first elastic member 2071 and the second elastic member 2072 are in a compressed state, and the third elastic member 2073 is in a normal state. After releasing the elastic force, the first elastic member 2071 is used to push the parallel slider module 203 to slide toward the proximal end, and after releasing the elastic force, the second elastic member 2072 is used to push the auxiliary needle module 205 toward the distal end to retract the auxiliary needle 2052, and the third elastic member 2073 is used to adjust the retraction stroke of the auxiliary needle module 205.

[0177] In some embodiments of the present invention, the third elastic member 2072 is disposed in the housing 201, with one end abutting against the inner side of the housing 201 and the other end facing the auxiliary needle module 205. After the first elastic member 2071 pushes the parallel slider module 203 toward the proximal end and the second elastic member 2072 pushes the auxiliary needle module 205 toward the distal end, the third elastic member 2073 blocks the auxiliary needle module 205 from continuing to slide toward the distal end, restricting the auxiliary needle module 205 from retracting to reduce its retraction stroke. If the third elastic member 2073 is not provided, when the auxiliary needle module 205 retracts, it will slide to the farthest end inside the housing 201 until it abuts against the housing 201. After the third elastic member 2073 is provided, the retraction stroke of the auxiliary needle module 205 can be adjusted according to the relative elastic force and length of the preset second elastic member 2072 and the third elastic member 2073, thereby adjusting the exposed length of the needle tip of the auxiliary needle 2052.

[0178] In some embodiments of the present invention, the reduction amount h3 of the retraction stroke of the auxiliary needle module 205 is equal to the length L of the third elastic member 2073 after the elastic forces of the second elastic member 2072 and the third elastic member 2073 are balanced.

[0179] In some embodiments of the present invention, the initial state of the third elastic member 2073 is a normal state, which is not compressed or stretched, and the initial state of the second elastic member 2072 is a compressed state. After the second elastic member 2072 releases its elastic force, the auxiliary needle module 205 is pushed to the distal end by the second elastic member 2072 until the auxiliary needle module 205 contacts the proximal end of the third elastic member 2073 and continues to slide to the distal end under the elastic force of the second elastic member 2072. The third elastic member 2073 is compressed and generates elastic force under the elastic force of the second elastic member 2072 until the elastic force of the third elastic member 2073 is the same as the elastic force of the second elastic member 2072 and reaches a balanced state, and the auxiliary needle module 205 stops sliding to the distal end.

[0180] In some embodiments of the present invention, the second elastic member 2072 and the third elastic member 2073 are springs, and their elastic modulus and initial length are preset before leaving the factory. After the auxiliary needle module 205 is retracted, when the third elastic member 2073 and the second elastic member 2072 have the same elastic force and are in a balanced state, the second elastic member 2072 is still in a compressed state. By adjusting the elastic modulus and initial length of the second elastic member 2072 and the third elastic member 2073, the length L of the third elastic member 2073 can be controlled when the second elastic member 2072 and the third elastic member 2073 reach elastic force balance, thereby controlling the retraction stroke of the auxiliary needle module 205 and the reduction h3 of the retraction stroke, and finally determining the length h2 of the auxiliary needle 2052 tip exposed from the housing 201.

[0181] In some embodiments of the present invention, after the auxiliary needle module 205 stops sliding, the user lifts the shell 201 from the skin surface, and the needle tip of the auxiliary needle 2052 is exposed outside the shell 201. Then the inner cover body 2023 is assembled onto the parallel slider module 203. The needle body protection cavity 20233 surrounds and seals the auxiliary needle 2052, and the inner cover body 2023 completes its protection function for the auxiliary needle 2052.

[0182] Figures 18a to 18c This is a schematic diagram of a protective sleeve used as a needle protection structure in an embodiment of the present invention.

[0183] Combined with reference Figures 18a to 18c In some embodiments of the present invention, the needle protection structure may also be an elastic protective sleeve 20523. After the user uses the mounting unit 200, the elastic protective sleeve 20523 may be assembled onto the auxiliary needle 2052 to protect the needle tip exposed outside the housing 201. The specific implementation will be described below.

[0184] by Fig.18b The directions shown are for reference. In some embodiments of the present invention, the elastic protective sleeve 20523 is a hollow three-dimensional structure with a distal opening, and the hollow structure is used to accommodate the auxiliary needle 2052. The outer diameter of the auxiliary needle 2052 is set to d3, and the inner diameter at the distal opening of the elastic protective sleeve 20523 is d4. The inner diameter d4 is slightly larger than the outer diameter d3 of the auxiliary needle 2052, for example, 0.1 to 2 mm larger, in order to facilitate the user to align the auxiliary needle 2052 and the distal opening of the elastic protective sleeve 20523. From the distal opening of the elastic protective sleeve 20523 to the proximal end, its inner diameter gradually decreases until it is reduced to d5. The inner diameter d5 is slightly smaller than the outer diameter d3 of the auxiliary needle 2052, for example, 0.1 to 2 mm smaller. Since the material of the elastic protective sleeve 20523 is elastic, the inner diameter d5 is slightly smaller than the outer diameter d3 of the auxiliary needle 2052, so that the elastic protective sleeve 20523 and the auxiliary needle 2052 achieve interference fit, increase the friction between the auxiliary needle 2052 and the elastic protective sleeve 20523, so that the elastic protective sleeve 20523 can be fixed relative to the auxiliary needle 2052 after being sheathed on the outside of the auxiliary needle 2052 and will not fall off. That is, the elastic protective sleeve 20523 and the auxiliary needle 2052 have a numerical size of d4>d3>d5. The proximal end of the elastic protective sleeve 20523 can be open or closed, and its overall length should be no less than the length h2 of the auxiliary needle 2052 exposed outside the housing 201, for example, 0.1 to 20 mm relatively long, so that the elastic protective sleeve 20523 can completely wrap the exposed needle tip to protect the auxiliary needle 2052. Preferably, the proximal end of the elastic protective sleeve 20523 is closed, which can prevent the needle tip of the auxiliary needle 2052 from being exposed from the proximal end of the elastic protective sleeve 20523.

[0185] In some embodiments of the present invention, before the user uses the installation unit 200, the elastic protective cover 20523 may be a structural component independent of the installation unit 200. After using the installation unit 200, the user puts the elastic protective cover 20523 on the auxiliary needle 2052 to form a whole with the installation unit 200.

[0186] In some embodiments of the present invention, since the elastic protective sleeve 20523 needs to have a certain elasticity to achieve an interference fit with the auxiliary needle 2052, the elastic protective sleeve 20523 can be made of elastic materials such as silicone and rubber. Any material changes of the elastic protective sleeve 20523 should be included in the protection scope of the present invention.

[0187] In some embodiments of the present invention, the elastic protective sleeve 20523 may not be limited to the above and Figures 18a to 18c The straight strip structure shown can also be other three-dimensional structures, such as a sphere, a cone or other irregular three-dimensional structures. Any shape change of the elastic protective sleeve 20523 should be included in the protection scope of the present invention.

[0188] In the aforementioned embodiments, after using the installation unit 200, an additional needle protection structure is required to protect the exposed needle tip, which increases the number of structural parts of the installation unit 200 and increases the design and processing costs. For the user, it also increases the operating steps of using the installation unit 200, which is not conducive to the user experience.

[0189] Fig.19a and Fig.19b It is a schematic diagram of the parallel slider module of the present invention as a needle body protection structure.

[0190] Based on the above problems, refer to Fig.19a and Fig.19b In some embodiments of the present invention, in order to avoid increasing the number of structural components of the installation unit 200, considering that the parallel slider module 203 itself is a necessary structural component of the installation unit 200, the parallel slider module 203 can be used as a protective structure for the auxiliary needle 2052. The details are described below.

[0191] In some embodiments of the present invention, reference Fig.19a and Fig.19b In the direction shown, the parallel slider module 203 includes a through hole 20323 for the auxiliary needle 2052 to pass through. The through hole 20323 and the auxiliary needle 2052 share a central axis, so that the auxiliary needle 2052 can pass through the through hole 20323 to achieve movement in the vertical direction relative to the parallel slider module 203.

[0192] In some embodiments of the present invention, as described above, when using the installation unit 200, the user operates the shell 201 to abut the skin surface. After triggering the installation unit 200, the elastic module pushes the parallel slider module 203 and the auxiliary needle module 205 to slide proximally relative to the shell 201 until the parallel slider module 203 and the analyte detection device 204 abut the skin surface. At this time, the analyte detection device 204 is automatically separated from the parallel slider module 203. At the same time, the auxiliary needle module 205 continues to move proximally relative to the shell 201 under the elastic force of the elastic module, so that the auxiliary needle 2052 penetrates the subcutaneous tissue. The auxiliary needle 2052 carries the in vivo part of the sensor 2042 into the subcutaneous tissue. Thereafter, the auxiliary needle 2052 retracts distally under the elastic force of the elastic module to exit the subcutaneous tissue. When the auxiliary needle 2052 is fully retracted, at least a portion of the auxiliary needle 2052 is exposed outside the shell 201, for example, the needle tip of the auxiliary needle 2052 is exposed outside the shell 201. Fig.15 As shown, the auxiliary needle 2052 no longer slides after being retracted.

[0193] In some embodiments of the present invention, after the auxiliary needle 2052 is retracted, the needle tip of the auxiliary needle 2052 is located in the through hole 20323 of the parallel slider module 203, and the through hole 20323 can provide safety protection for the needle tip of the auxiliary needle 2052. After using the installation unit 200, the needle tip of the auxiliary needle 2052 will not cause unnecessary harm to the user. Since the needle tip of the auxiliary needle 2052 is exposed outside the housing 201 after the auxiliary needle 2052 is retracted, for example, the exposed length of the auxiliary needle 2052 is h4, then the proximal end surface of the through hole 20323 protrudes relative to the housing 201 by at least h4, so that the needle tip of the auxiliary needle 2052 can be completely accommodated in the through hole 20323.

[0194] In some embodiments of the present invention, before the user removes the mounting unit 200, the first elastic member 2071 in the elastic module is still in a compressed state, and the parallel slider module 203 abuts against the skin surface, so that a portion of the elastic force of the first elastic member 2071 is not released. After the user removes the mounting unit 200, since the parallel slider module 203 no longer abuts against the skin surface, the first elastic member 2071 in the elastic module releases the elastic force, pushing the parallel slider module 203 to continue to slide proximally relative to the housing 201 until the parallel slider module 203 slides to the first predetermined position, at which time the through hole 20323 of the parallel slider module 203 accommodates the needle tip of the auxiliary needle 2052, such as Fig.19a and Fig.19b As shown, although the needle tip of the auxiliary needle 2052 protrudes from the housing 201 , the needle tip of the auxiliary needle 2052 will not cause unnecessary harm to the user due to the protection of the through hole 20323 of the parallel slider module 203 .

[0195] In some embodiments of the present invention, the inner diameter of the through hole 20323 is slightly larger than the outer diameter of the auxiliary needle 2052 so as to allow the auxiliary needle 2052 to pass through.

[0196] In some embodiments of the present invention, the through hole 20323 may be cylindrical with a uniform inner diameter along the axial direction.

[0197] In some embodiments of the present invention, the through hole 20323 may be funnel-shaped with an inner diameter decreasing from the distal end to the proximal end. The larger inner diameter at the distal end facilitates the auxiliary needle 2052 to enter the through hole 20323, and the smaller inner diameter at the proximal end may limit the swing of the auxiliary needle 2052, thereby ensuring that the auxiliary needle 2052 moves in the vertical direction. After the installation unit 200 is used, the auxiliary needle 2052 is retracted and the needle tip is accommodated at the proximal end of the through hole 20323.

[0198] In some embodiments of the present invention, when the parallel slider module 203 is in the first predetermined position, the parallel slider module 203 is in an active state relative to the housing 201, and is held back by the first elastic member 2071 so as not to be retracted into the housing 201. However, after using the installation unit 200, if the user accidentally presses the parallel slider module 203 and applies a force greater than the elastic force of the first elastic member 2071, the first elastic member 2071 is compressed, and the parallel slider module 203 may be pushed into the housing 201, and the needle tip of the auxiliary needle 2052 may be exposed, which may still cause unnecessary harm to the user. Therefore, after using the installation unit 200, the position of the parallel slider module 203 needs to be fixed so that the parallel slider module 203 can no longer be retracted into the housing 201, so that the through hole 20323 of the parallel slider module 203 can form a safe protection for the needle tip of the auxiliary needle 2052.

[0199] In some embodiments of the present invention, a fixing structure, such as a fixing buckle 2031, is provided on the outer edge of the parallel slider module 203. When the parallel slider module 203 is in the first predetermined position, the fixing buckle 2031 is buckled and connected with the trigger module 206 on the inner edge of the trigger module 206. After the user uses the installation unit 200, even if pressure is applied to the parallel slider module 203, the parallel slider module 203 will no longer retract into the interior of the shell 201. Therefore, the through hole 20323 of the parallel slider module 203 can form a safe protection for the needle tip of the auxiliary needle 2052.

[0200] In some embodiments of the present invention, before using the installation unit 200, the parallel slider module 203 is located inside the housing 201, and the fixing buckle 2031 is also located inside the housing 201. During the use of the installation unit 200, as the parallel slider module 203 is pushed toward the proximal end by the first elastic member 2071, when the fixing buckle 2031 abuts against the inner edge of the triggering module 206, the elastic force of the first elastic member 2071 continues to push the fixing buckle 2031, as shown in FIG. Fig.19a and Fig.19b The bending direction of the curved arrow makes the fixing buckle 2031 avoid interfering with the trigger module 206 and affecting the normal use of the installation unit 200.

[0201] In some embodiments of the present invention, since the fixing buckle 2031 needs to bend during use and needs to return to its original shape after bending, the fixing buckle 2031 can be made of a material with a certain elasticity, such as polypropylene, polyvinyl chloride, elastic metal parts, etc.

[0202] In some embodiments of the present invention, the number of fixing buckles 2031 should be no less than 2, and they are arranged at a certain distance on the outer edge of the parallel slider module 203. Preferably, the number of fixing buckles 2031 is 3, and they are arranged at equal distances on the outer edge of the parallel slider module 203.

[0203] In some embodiments of the present invention, the fixing buckle 2031 is integrally formed with the parallel slider module 203. Fig.19a As shown, the fixing buckle 2031 is used as a structural member independent of the parallel slider module 203 and is fixed on the parallel slider module 203 by welding, pasting, threading, etc. Fig.19b shown.

[0204] In some embodiments of the present invention, a buckle slider 2032 may be further provided on the outer edge of the parallel slider module 203, and correspondingly, a buckle slide groove 2011 is provided on the inner side of the housing 201, and the buckle slider 2032 may slide in the buckle slide groove 2011. The buckle slide groove 2011 restricts the buckle slider 2032, on the one hand, to prevent the parallel slider module 203 from rotating during the proximal movement relative to the housing 201, so that the position of the parallel slider module 203 moves; on the other hand, when the parallel slider module 203 reaches the first predetermined position, the buckle slider 2032 abuts against the trigger module 206, so that the parallel slider module 203 is prevented from being completely pushed out of the housing 201 by the first elastic member 2071, so that the parallel slider module 203 falls off.

[0205] In some embodiments of the present invention, the buckle slider 2032 can be integrally formed with the fixed buckle 2031 and located at the same position on the outer edge of the parallel slider module 203 to reduce the difficulty of design and processing. In other embodiments of the present invention, the buckle slider 2032 can also be independently arranged on the outer edge of the parallel slider module 203 from the fixed buckle 2031, and the two are located at different positions on the outer edge of the parallel slider module 203, and are distributed on the outer edge of the parallel slider module 203 at a certain distance. Preferably, the number of the buckle sliders 2032 and the fixed buckle 2031 are both 3, and they are equidistantly arranged on the outer edge of the parallel slider module 203, that is, the interval angle between adjacent buckle sliders 2032 and fixed buckles 2031 is 60°, and the interval angle between two adjacent buckle sliders 2032 or two adjacent fixed buckles 2031 is 120°. In some other embodiments of the present invention, the parallel slider module 203, the buckle slider 2032 and the fixed buckle 2031 are integrally formed, which can further reduce the difficulty of design and processing.

[0206] In summary, an embodiment of the present invention discloses an installation unit for an analyte detection device. After the installation unit is used, the through hole on the parallel slider module accommodates the needle tip of the auxiliary needle, and the parallel slider module is fixed relative to the trigger module by a fixing structure to prevent the parallel slider module from retracting into the interior of the installation unit housing. The parallel slider module can provide effective safety protection for the auxiliary needle without adding additional structural parts, and is also conducive to the miniaturized design of the installation unit.
