Description

TECHNICAL FIELD

[0002] The pancreas in a normal human body can automatically detect the glucose content in the human blood and automatically secrete the required insulin / glucagon. However, the pancreas of a diabetic patient is abnormal and cannot normally secrete the required insulin. Therefore, diabetes is a metabolic disease caused by abnormal function of the human pancreas, 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] A diabetic patient needs to detect blood sugar before injecting insulin into the body. Most current detection methods can continuously detect blood sugar and send blood sugar data to external devices in real time, which is convenient for users to view. This detection method is called continuous glucose monitoring (CGM). In order to realize continuous glucose monitoring, the user needs to use an auxiliary installation unit to install the blood sugar analyte detection device on the skin surface. The smaller the size of the installation unit, the more convenient the user uses, and the lower the manufacturing cost. Therefore, under the premise of realizing the function of the installation unit, the miniaturization design of the installation unit is beneficial. When using the installation unit, reducing the retraction stroke of the auxiliary needle is a design idea for miniaturization of the installation unit.

The sensor 1042 is used to detect the analyte parameter information of the user's body fluid, and the above analyte parameter information is transmitted to the transmitter through the internal circuit, and then transmitted to the external device 200 by the transmitter.

[0093] In the preferred embodiments of the present application, the analyte detection device 104 emits signals to the external device 200 at a first frequency f1 before being installed on the surface of the user's skin, and emits signals to the external device 200 at a second frequency f2 after being installed on the surface of the user's skin, and the second frequency f2 is greater than the first frequency f1.

[0096] In the embodiment of the utility model, the lower shell body 10413 includes a first through hole 10414, and correspondingly, the upper shell body 10411 includes a second through hole (not shown in the figure) on the axis of the first through hole 10414, and the in-vivo part passes through the first through hole 10414 to the outside of the shell to facilitate the penetration of the user's subcutaneous tissue.

[0097] In the embodiment of the utility model, the side of the upper shell body 10411 includes a clamping hole 10412 corresponding to the T-shaped structure buckle 10352, and here, "corresponding" means that the position and number of the clamping hole 10412 are consistent with the T-shaped structure buckle 10352. In the installation unit 100, the upper shell body 10411 is attached to the proximal end surface 1034, the T-shaped structure buckle 10352 is clamped and connected with the clamping hole 10412, and the analyte detection device 104 is fixed on the parallel sliding block module 103.

The hollow structure of the semi-enclosed needle body 10522 can be used to accommodate the in-vivo part of the sensor 1042, and when the semi-enclosed needle body 10522 penetrates the user's subcutaneous tissue, the in-vivo part can also be penetrated into the subcutaneous tissue, and when the needle body is retracted, it does not affect the state of the in-vivo part in the subcutaneous tissue.

[0103] In other embodiments of the present application, the auxiliary needle 1052 only includes a semi-enclosed needle body 10522, that is, the semi-enclosed needle body 10522 is fixedly connected with the auxiliary needle fixing block 10512, so that the material of the auxiliary needle 1052 can be reduced, and the cost can be saved, but the rigidity of the auxiliary needle 1052 is also reduced.

[0104] In the installation unit 100, the auxiliary needle 1052 sequentially passes through the second through hole and the first through hole 10414, so as to penetrate the analyte detection device 104, and the in-vivo part of the sensor 1042 is located in the semi-enclosed needle body 10522.

[0120] Combined with reference Figure 10a And Figure 10bIn the embodiment of the utility model, the clamping groove 1014 is provided with two clamping groove positions, a first clamping groove position 10141 and a second clamping groove position 10142. Before the installation unit 100 is used, the trigger module 106 is fixed on the shell 101 through the clamping of the clamping ear 1062 and the first clamping groove position 10141, at this time, the fixed clamping buckle 1061 contacts the first clamping buckle 1012, preventing the first clamping buckle 1012 from bending or folding to the outside of the shell 101, and the fixed clamping buckle 1061, the first clamping buckle 1012 and the second clamping buckle 1033 are located on the same horizontal line. In the preferred embodiment of the utility model, from inside to outside of the shell 101, they are the second clamping buckle 1033, the first clamping buckle 1012 and the fixed clamping buckle 1061 in turn.

[0121] In the embodiment of the utility model, the contact between the fixed clamping buckle 1061 and the first clamping buckle 1012 is one of point contact, line contact or surface contact, when the contact is surface contact, the extension line m1 of the contact surface converges at the proximal end, and this structure design can make the fixed clamping buckle 1061 slide to the distal end relative to the first clamping buckle 1012.

[0122] In the preferred embodiment of the utility model, the coupling surface of the second clamping buckle 1033 and the first clamping buckle 1012 is a plane, the plane forms a fixed angle with the horizontal plane, and the extension end m2 converges at the proximal end.

[0123] Combined with reference Figure 11 This structure design can make the second clamping buckle 1033 slide to the proximal end relative to the first clamping buckle 1012, push the first clamping buckle 1012 away from the outside of the shell 101, and thus release the coupling state between the first clamping buckle 1012 and the second clamping buckle 1033.

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

[0125] In the embodiment of the utility model, when using the installation unit 100, the outer cover body 1021 is rotated, the stand column 10211 is broken, the protective cover 102 is separated from the shell 101, the proximal end of the installation unit 100 is close to the skin of the user, 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, the shell 101 slides towards the skin, the trigger module 106 remains stationary, therefore the trigger module 106 slides towards the distal end relative to the shell 101, the clamping ear 1062 is separated from the first clamping groove 10141 and enters the second clamping groove 10142, at the same time the fixed clasp 1061 no longer contacts the first clasp 1012, the first clasp 1012 is curved or bent to the outside of the shell 101 due to the component force Fsin, the coupling state of the first clasp 1012 and the second clasp 1033 is released.

[0126] In the embodiment of the utility model, after the coupling state is released, the parallel slider module 103 continues to slide towards the proximal end under the elastic force of the first elastic member 1071, at the same time the analyte detection device 104 is driven to slide towards the proximal end until the lower outer shell 10413 of the analyte detection device 104 contacts the skin surface of the user.

[0127] Refer to Figure 10c In the embodiment of the utility model, the slider clasp 10321 is clasp connected with the auxiliary needle slider 10511, when the first elastic member 1071 pushes the parallel slider module 103 to slide towards the proximal end, the auxiliary needle module 105 is driven to slide towards the proximal end together.

[0128] In the embodiment of the utility model, the connection between the slider clasp 10321 and the auxiliary needle slider 10511 is a plane or an approximate plane, the plane forms a fixed angle with the horizontal plane, and the extension line m3 converges at the distal end. The pushing force of the second elastic member 1072 on the auxiliary needle slider 10511 is towards the distal end, therefore the auxiliary needle slider 10511 can push the slider clasp 10321 to the outside of the shell 101, so that the slider clasp 10321 is curved or bent, and the principle is equivalent to Figure 11 .

[0129] In the embodiment of the utility model, in the installation unit 100, the side wall of the auxiliary needle limiting groove 1015 prevents the bending or bending of the sliding block buckle 10321, and the buckle connection state of the sliding block buckle 10321 and the auxiliary needle sliding block 10511 does not change. With the sliding of the parallel sliding block module 103 and the auxiliary needle module 105 to the proximal end, until the sliding block buckle 10321 is separated from the auxiliary needle limiting groove 1015, the inner wall of the auxiliary needle limiting groove 1015 no longer prevents the bending or bending of the sliding block buckle 10321, the second elastic member 1072 pushes the auxiliary needle sliding block 10511 to the distal end, and at the same time the auxiliary needle sliding block 10511 pushes the sliding block buckle 10321 to bend or bend outward, the buckle connection of the sliding block buckle 10321 and the auxiliary needle sliding block 10511 is released, the second elastic member 1072 continues to push the auxiliary needle sliding block 10511 to slide to the distal end, and finally the auxiliary needle module 105 returns to the initial position, the auxiliary needle 1052 is retracted into the shell 101, preventing the auxiliary needle 1052 from being exposed outside the shell 101, and avoiding unnecessary harm.

[0130] In the embodiment of the utility model, when the sliding block buckle 10321 is separated from the auxiliary needle limiting groove 1015, the half-enclosed needle body 10522 of the auxiliary needle pierces into the user's subcutaneous tissue.

[0131] In the embodiment of the utility model, in the installation unit 100, the T-shaped structure sliding block 10351 is located in the limiting groove 1013, the limiting groove 1013 limits the position and direction of the parallel sliding block module 103 through the T-shaped structure sliding block 10351, to ensure that the parallel sliding block module 103 and its sliding direction are perpendicular, so that the analyte detection device 104 arranged at the front end of the parallel sliding block module 103 and its sliding direction are perpendicular, and at the same time the auxiliary needle 1052 and its sliding direction are parallel, so that the auxiliary needle 1052 and the sensor body part in its envelope can be pierced into the user's subcutaneous tissue at a perpendicular angle, reducing the user's pain.

[0132] In the embodiment of the utility model, in the process of sliding the parallel sliding block module 103 to the proximal end, the T-shaped structure sliding block 10351 slides in the limiting groove 1013 until it contacts the outer ring 1063 of the trigger module 106, under the push of the first elastic member 1071, the parallel sliding block module 103 continues to slide to the proximal end, and the outer ring 1063 blocks the T-shaped structure sliding block 10351 from continuing to slide to the proximal end, so the T-shaped structure sliding block 10351 bends or bends around the vertical part, the buckle connection of the T-shaped structure buckle 10352 and the clamping hole 10412 is released, and the analyte detection device 104 is separated from the parallel sliding block module 103, so that it can be installed on the surface of the user's skin.

[0133] In the embodiment of the utility model, when the T-shaped structure slider 10351 contacts with the outer ring 1063, the position of the parallel slider module 103 is the predetermined position, at this time, the lower outer shell body 10413 of the analyte detection device contacts with the skin surface of the user.

[0134] In the embodiment of the utility model, 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 the half-enclosed needle body 10522 of the auxiliary needle envelopes the sensor 1042. During the sliding process of the parallel slider module 103 and the auxiliary needle module 105 to the proximal end, the half-enclosed needle body 10522 carries the sensor 1042 to penetrate into the subcutaneous tissue, after the auxiliary needle 1052 is retracted, the in-vivo part of the sensor 1042 remains in the subcutaneous tissue, and the needle body does not affect the state of the in-vivo part of the sensor 1042 when being retracted.

[0135] In the embodiment of the utility model, when the installation action is implemented, the user needs to press the shell 101 at the distal end, and the force F is applied to the shell 101 to the proximal end, the outer ring 1063 of the trigger module 106 contacts the skin surface of the user, the skin of the user gives the outer ring 1063 with the force F' opposite to the force F, so that the relative sliding of the trigger module 106 and the shell 101 is realized. In the actual installation process, the absolute position of the trigger module 106 remains unchanged, and the shell 101 slides to the proximal end.

[0136] Before the installation action is implemented, in order to prevent the trigger module 106 from sliding relative to the shell 101, the protective cover 102 is installed at the proximal end of the shell 101, the protective cover 102 surrounds the outer ring 1063 outside the trigger module, which can prevent the installation action from being implemented at the incorrect position due to accidental contact with the outer ring 1063, and plays a role of preventing triggering.

[0137] The distal end surface 10232 of the inner cover body 1023 contacts with 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, preventing dust, particles and other dirt in the outside from contacting the needle body and the sensor, causing pollution.

[0138] In the embodiment of the utility model, the lower outer shell body 10413 of the analyte detection device is also provided with adhesive tape (not shown in the figure), which is used for fixing the analyte detection device 104 on the skin surface of the user.

[0139] Second embodiment

[0140] In the foregoing embodiment, after the user uses the installation unit, the auxiliary needle is automatically retracted into the shell under the action of the second elastic member to avoid unnecessary harm to the user. The auxiliary needle is completely retracted into the shell, and a 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 utility model 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, protective measures for the auxiliary needle need to be considered, and a needle body protection structure is designed for the auxiliary needle.

[0141] In the foregoing technical background, in some embodiments of the utility model, 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 part of the auxiliary needle, such as the needle tip, is exposed outside the shell. The user assembles the needle body protection structure to the installation unit to protect the exposed needle tip. The specific implementation of the needle body protection structure will be described in detail below.

[0142] In the embodiment of the utility model, the technical solutions not described are regarded as the same as the foregoing embodiments, and will not be described here.

[0143] Figure 12 The explosion structure schematic diagram of the analyte detection device installation unit of the embodiment of the utility model is shown. Figure 13a The separation structure schematic diagram of the outer cover body and the inner cover body of the embodiment of the utility model is shown. Figure 13b The integrated structure schematic diagram of the outer cover body and the inner cover body of the embodiment of the utility model is shown. Figure 13c The structure schematic diagram of the outer cover body of the embodiment of the utility model is shown.

[0144] Refer to Figure 12 In some embodiments of the utility model, the installation unit 200 includes a shell 201 and a protective cover 202. As described before, before installation, the analyte detection device 204 is pre-installed inside the shell 201, and during installation, it is pushed to the proximal end by an elastic module (not shown in the figure, refer to Figure 17 The protective cover 202 is arranged at the proximal end of the shell 201 and is releasably connected with the shell 201, and is used to protect the structural members inside the shell 201 before installation.

[0145] Refer to Figures 13a-13cIn some embodiments of the utility model, 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 Fig. 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, so as to seal the inner cover body 2023 in the outer cover body cavity 20214.

[0146] In some embodiments of the utility model, the inner cover body 2023 is in a movable state or a releasable connection state relative to the outer cover body 2021. When the inner cover body 2023 is in a movable state relative to the outer cover body 2021, the outer cover body 2021 has no restraining structure for the inner cover body 2023 to limit the state of the inner cover body 2023 in the outer cover body 2021. When needed, the user can directly take out the inner cover body 2023 from the outer cover body 2021. When the inner cover body 2023 is in a releasable connection state relative to the outer cover body 2021, the inner cover body 2023 and the outer cover body 2021 are fixed together by means of buckles, hooks, threads, magic tapes and the like. When needed, the user needs to first release the fixed connection between the inner cover body 2023 and the outer cover body 2021, and then take out the inner cover body 2023 from the outer cover body 2021 after the inner cover body 2023 and the outer cover body 2021 are separated. In the preferred embodiment of the utility model, in order to facilitate the user to 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 take out the inner cover body 2023 from the outer cover body 2021 when using the installation unit 200.

[0147] In some embodiments of the utility model, 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 towards the distal end and forms an outer cover body cavity 20214 with a proximal end 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, there is a gap of 0.5-5mm 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, so as to avoid the inner cover body 2023 protruding from the outer cover body cavity 20214, so as to facilitate the label paper 2024 to be pasted on the proximal end surface 20215 of the outer cover body 2021 to seal the outer cover body cavity 20214.

[0148] In some embodiments of the utility model, on the proximal end surface 20232 of the inner cover body 2023, a plurality of convex semicircle balls 20234 are further arranged. Before the installation unit 200 is used, the inner cover body 2023 is accommodated in the outer cover body cavity 20214, and the label paper 2024 is pasted on the proximal end surface 20215 of the outer cover body 2021. The adhesive coating area of the label paper 2024 may exceed the contact area of the label paper 2024 and the outer cover body 2021, causing the adhesive coating of the label paper 2024 to contact the proximal end surface 20232 of the inner cover body 2023, and the inner cover body 2023 is pasted with the label paper 2024. When the inner cover body 2023 is taken out, the user has difficulty tearing off the label paper 2024, and even when tearing off the label paper 2024, it is broken and adheres to the inner cover body 2023, affecting the user's experience. Based on this, a plurality of convex semicircle balls 20234 are arranged on the proximal end surface 20232 of the inner cover body 2023, which contact the label paper 2024, can reduce the contact area of the proximal end surface 20232 of the inner cover body 2023 and the label paper 2024, and can avoid the label paper 2024 being adhered to the proximal end surface 20232 of the inner cover body 2023 in a large area, facilitating the user to tear off the label paper 2024.

[0149] In some embodiments of the utility model, the number of convex semicircle balls 20234 is at least 2, which are symmetrically or asymmetrically distributed on the proximal end surface of the inner cover body 2023. Preferably, the convex semicircle balls 20234 are symmetrically and uniformly distributed on the proximal end surface of the inner cover body 2023.

[0150] In some embodiments of the utility model, information related to the analyte detection device 204, the installation unit 200 and other equipment can be printed on the label paper 2024, such as production batch number, production date, usage instructions, communication connection SN code, trademark, two-dimensional code and the like.

[0151] In some embodiments of the utility model, before the installation unit 200 is used, the protective cover 202 is releasably connected with the shell 201, and the specific use mode has been described in the first embodiment, which will not be repeated here. When the protective cover 202 is installed on the shell 201, the needle body accommodating cavity 20213 on the outer cover body 2021 can accommodate the auxiliary needle 2052, and the needle body accommodating cavity 20213 is an opening towards the distal end (the opening is not shown in the figure) Figure 13aThe needle body accommodating cavity 20213 can be a hollow frustum or a hollow cone. When the needle body accommodating cavity 20213 is a hollow cone, the diameter of the needle body accommodating cavity 20213 gradually decreases from the distal end to the proximal end. The inside of the needle body accommodating cavity 20213 can be a hollow structure parallel to the outside structure, or a hollow structure with a decreasing inner diameter from the distal end to the proximal end. The auxiliary needle 2052 shares the central axis with the needle body accommodating cavity 20213, so that the auxiliary needle 2052 can enter the hollow cavity from the distal end of the needle body accommodating cavity 20213. The needle body accommodating cavity 20213 protects the auxiliary needle 2052 while effectively utilizing the internal space of the shell 201, and the structure is more compact.

[0152] Figure 14 A state diagram of the installation unit after use in an embodiment of the present application.

[0153] Referring to Figure 14 In some embodiments of the present application, the user places the installation unit 200 on the skin surface, the trigger module 206 is in contact with the skin, and the user applies pressure to the installation unit 200 from the distal end to the proximal end. The shell 201 slides towards the proximal end relative to the trigger module 206, and during the process of the shell 201 sliding towards the proximal end 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 sliding block module 203, the analyte detection device 204 and the auxiliary needle 2052 are pushed to slide towards the proximal end together, until the analyte detection device 204 is in contact with the skin surface and the auxiliary needle 2052 penetrates into the subcutaneous tissue.

[0154] Referring to Figure 14 In some embodiments of the present application, during the process of the parallel sliding block module 203, the analyte detection device 204 and the auxiliary needle 2052 sliding towards 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 sliding block module 203 is in the third predetermined position at this time, the adhesive tape (not shown in the figure) at the proximal end of the analyte detection device 204 is in contact with the skin surface of the user, and the elastic module still has a proximal end pushing force on the parallel sliding block module 203. The parallel sliding block module 203 continues to slide towards the proximal end relative to the shell 201 with the analyte detection device 204 and the auxiliary needle 2052 carried thereon, and the analyte detection device 204 at the proximal end of the parallel sliding block 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 of the adhesive tape on 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 utility model, during the process that parallel slider module 203 continues to slide to the proximal end relative to shell 201, the position of parallel slider module 203 no longer changes due to the obstruction of the skin surface, if the elastic element in the elastic module still has elastic force that is not completely released, at this time, the elastic module pushes shell 201 to slide to the distal end relative to parallel slider module 203, and carries trigger module 206 away from the skin surface until the proximal end surface of trigger module 206 and the proximal end surface of parallel slider module 203 form a height difference h1, at this time, parallel slider module 203 is located at the first predetermined position, and the skin surface forms a pit under the extrusion of analyte detection device 204 and parallel slider module 203.

[0156] In some embodiments of the utility model, during the process that parallel slider module 203 continues to slide to the proximal end relative to shell 201, the buckle connection of parallel slider module 203 and analyte detection device 204 is decoupled, when the relative sliding of parallel slider module 203 and shell 201 terminates, parallel slider module 203 has completed separation from analyte detection device 204, and parallel slider module 203 is still limited in shell 201, at this time, analyte detection device 204 is in a separated state relative to shell 201, and the user can hold shell 201 to the distal end, and analyte detection device 204 is pasted on the skin surface through adhesive tape.

[0157] In some embodiments of the utility model, when parallel slider module 203 slides to the proximal end relative to shell 201 to the first predetermined position, auxiliary needle module 205 slides to the proximal end relative to the shell to the end point, at this time, auxiliary needle 2052 penetrates into the subcutaneous tissue, and the in-vivo part of sensor 2042 is sent to the predetermined depth of the subcutaneous tissue. Subsequently, auxiliary needle module 205 retracts and slides to the distal end relative to shell 201 to the second predetermined position.

[0158] Figure 15 It is the state schematic view of the retraction of the auxiliary needle of the installation unit of the utility model embodiment.

[0159] Referring to Figure 15 In some embodiments of the utility model, after auxiliary needle module 205 slides to the distal end to the second predetermined position, i.e. the retraction end point, auxiliary needle 2052 exits the subcutaneous tissue, facilitating the user to remove shell 201. After the retraction of auxiliary needle 2052, the in-vivo part of sensor 2042 remains in the subcutaneous tissue.

[0160] In some embodiments of the utility model, after the retraction of auxiliary needle 2052, when auxiliary needle module 205 is at the second predetermined position, auxiliary needle 2052 exposes a needle tip outside shell 201, like Figure 15As shown, the needle tip of the auxiliary needle 2052 forms a height difference h2 to the proximal end face of the parallel slider module 203, that is, the length of the auxiliary needle 2052 exposed outside the shell 201 is h2, which can be taken in the range of 0.1-5 mm. If the exposed length of the auxiliary needle 2052 is too long, the needle tip will be left in the subcutaneous tissue when retracted, which may cause injury to the skin or body when the user removes the shell 201.

[0161] In some embodiments of the present application, the auxiliary needle 2052 exposes a part of the needle tip outside the shell 201 after retraction, rather than being completely retracted into the shell 201, which can reduce the retraction stroke of the auxiliary needle 2052, thereby reducing the overall height of the shell 201, making the installation unit 200 more compact and smaller in mass, while also reducing the material usage of the shell 201 and reducing the production cost of the installation unit 200. Figure 15 In some embodiments of the present application, the auxiliary needle module 205 represented by the dashed line represents the final position of the auxiliary needle module 205 after and before the reduction of the retraction stroke, respectively. The one closer to the distal end is the final position of the auxiliary needle module 205 before the reduction of the retraction stroke, and the one closer to the proximal end is the final position of the auxiliary needle module 205 after the reduction of the retraction stroke.

[0162] In some embodiments of the present application, the reduction of the retraction stroke of the auxiliary needle 2052 means that the auxiliary needle module 205 reduces the same retraction stroke. Referring to Figure 15 , the auxiliary needle module 205 reduces the retraction stroke by h3, and after the auxiliary needle module 205 reduces the retraction stroke, the overall height of the shell 201 can be reduced, and the overall height of the shell 201 reduced can be consistent with the reduction of the retraction stroke of the auxiliary needle module 205, both being h3.

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

[0164] Figures 16a-16c The present application is a schematic view of the inner cover body as a needle body protection structure in the embodiments of the present application.

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

[0166] In some embodiments of the utility model, with the inner cover body 2023 and parallel slider module 203 assembly for embodiment is described, the inner cover body 2023 is a needle body protection structure of the utility model embodiment.The proximal end face of parallel slider module 203 is relative to the proximal end face area of trigger module 206 or shell 201 larger, more easily process assembly structure.

[0167] In some embodiments of the utility model, refer to Figure 16b The needle body protection cavity 20233 is a hollow cavity with a distal opening, and the hollow cavity on the inner side can be used to accommodate the exposed needle tip of the auxiliary needle 2052.The outer side of the needle body protection cavity 20233 can be a cylinder, a cone, a cuboid or other irregular solid structure, which is not limited herein, and the inner cavity can be the same or different shape as the outer side, preferably, the inner cavity is a cylinder or a cone, more preferably, the inner cavity is a cone with a gradually decreasing inner diameter from the distal end to the proximal end.

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

[0169] In some embodiments of the utility model, the inner cover body 2023 and the parallel slider module 203 are connected by one or more of buckles, hooks, blocks, threads, bolts, magic tape, glue, etc.The assembly method that can assemble the inner cover body 2023 to the parallel slider module 203 should be included in the protection scope of the utility model.At least two assembly structures are provided on the corresponding positions of the inner cover body 2023 and the parallel slider module 203, preferably, the assembly structures are symmetrically distributed on the inner cover body 2023 and the parallel slider module 203.

[0170] In some embodiments of the utility model, the assembly structure can be interchanged on the inner cover body 2023 and the parallel slider module 203, for example, the inner cover body 2023 is provided with a hook 20231 on the distal end face, and the corresponding card hole 2037 is provided on the proximal end face of the parallel slider module 203 for establishing assembly connection with the hook 20231.In some other embodiments of the utility model, the hook 20231 can be provided on the parallel slider module 203, and the corresponding card hole 2037 is provided on the inner cover body 2023.

[0171] In some embodiments of the utility model, in order to facilitate user assembly inner cover body 2023, and increase the assembly firmness of inner cover body 2023, still be provided with positioning structure on inner cover body 2023 and parallel slider module 203.Positioning structure is composed of positioning column 20232 and positioning hole 2036, and the position and quantity on inner cover body 2023 and parallel slider module 203 correspond.

[0172] In some embodiments of the utility model, positioning column 20232 can be located at the distal end face of inner cover body 2023, and positioning hole 2036 is located at the proximal end face of parallel slider module 203.In other embodiments of the utility model, positioning hole 2036 can be located at the distal end face of inner cover body 2023, and positioning column 20232 is located at the proximal end face of parallel slider module 203.

Figures 16a-16c

[0174] In some embodiments of the utility model, the user holds inner cover body 2023 and shell 201 respectively with hands and approaches each other, aligns the assembly structure and positioning structure, and then places auxiliary needle 20522 on the central axis of needle body protection cavity 20233, and presses inner cover body 2023 and shell 201, so that inner cover body 2023 is assembled on parallel slider module 203, and needle body protection cavity 20233 wraps auxiliary needle 20522 to close and protect the exposed needle tip.The state diagram of inner cover body 2023 assembled on parallel slider module 203 is shown in the figure. Figure 16c

[0175] Figure 17 The cross-sectional structure diagram of the installation unit of the embodiments of the utility model.

[0176] Referring to Figure 17 In some embodiments of the utility model, the elastic module includes first elastic member 2071, second elastic member 2072 and third elastic member 2073.Before using installation unit 200, first elastic member 2071 and second elastic member 2072 are in compression state, and third elastic member 2073 is in normal state.After releasing the elastic force, first elastic member 2071 is used to push parallel slider module 203 to slide towards the proximal end, second elastic member 2072 is used to push auxiliary needle module 205 towards the distal end to retract auxiliary needle 2052, and third elastic member 2073 is used to adjust the retraction stroke of auxiliary needle module 205.

[0177] ​​In some embodiments of the utility model, third elastic piece 2072 is arranged in the shell 201, one end is abutted with the inner side of shell 201, the other end is towards auxiliary needle module 205. After first elastic piece 2071 pushes parallel slider module 203 to the proximal end, second elastic piece 2072 pushes auxiliary needle module 205 to the distal end, third elastic piece 2073 blocks auxiliary needle module 205 to continue to slide to the distal end, limits the retraction of auxiliary needle module 205 to reduce its retraction stroke. If third elastic piece 2073 is not set, when auxiliary needle module 205 retracts, it will slide to the farthest end inside the shell 201 until abutting the shell 201. After setting third elastic piece 2073, the retraction stroke of auxiliary needle module 205 can be adjusted according to the relative elastic force and length of second elastic piece 2072 and third elastic piece 2073, and then the length of the needle tip of auxiliary needle 2052 exposed is adjusted.

[0178] In some embodiments of the utility model, the reduction amount h3 of the retraction stroke of auxiliary needle module 205 is equivalent to the length L of third elastic piece 2073 after the elastic force of second elastic piece 2072 and third elastic piece 2073 is balanced.

[0179] In some embodiments of the utility model, the initial state of third elastic piece 2073 is normal state, not compressed or stretched, and the initial state of second elastic piece 2072 is compressed state. After the elastic force of second elastic piece 2072 is released, auxiliary needle module 205 is pushed to the distal end by second elastic piece 2072 until auxiliary needle module 205 contacts the proximal end of third elastic piece 2073 and continues to slide to the distal end under the action of the elastic force of second elastic piece 2072. Third elastic piece 2073 is compressed and generates elastic force under the action of the elastic force of second elastic piece 2072 until the elastic force of third elastic piece 2073 is the same as that of second elastic piece 2072 and reaches the balance state, and auxiliary needle module 205 stops sliding to the distal end.

[0180] In some embodiments of the utility model, second elastic piece 2072 and third elastic piece 2073 are springs, and their elastic modulus and initial length are preset before leaving the factory. When third elastic piece 2073 and second elastic piece 2072 are in the balanced state with the same elastic force after the retraction of auxiliary needle module 205, second elastic piece 2072 is still in the compressed state. By adjusting the elastic modulus and initial length of second elastic piece 2072 and third elastic piece 2073, the length L of third elastic piece 2073 when second elastic piece 2072 and third elastic piece 2073 reach the elastic balance can be controlled, and then the retraction stroke of auxiliary needle module 205 and the reduction amount h3 of the retraction stroke can be controlled, and finally the length h2 of the needle tip of auxiliary needle 2052 exposed from the shell 201 is determined.

[0181] In some embodiments of the utility model, after the auxiliary needle module 205 stops sliding, the user takes the shell 201 from the skin surface, the needle tip of the auxiliary needle 2052 is exposed outside the shell 201, then the inner cover body 2023 is assembled to 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 the protection function of the auxiliary needle 2052.

[0182] Figures 18a-18c The protective sleeve of the utility model embodiment is as a schematic view of a needle body protection structure.

[0183] In combination with reference Figures 18a-18c In some embodiments of the utility model, the needle body protection structure can also be an elastic protective sleeve 20523. After the user uses the installation unit 200, the elastic protective sleeve 20523 can be assembled to the auxiliary needle 2052 to protect the needle tip exposed outside the shell 201, and the specific embodiment will be described below.

[0184] In the direction shown Figure 18b In some embodiments of the utility model, 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 d3, and the inner diameter of the distal opening of the elastic protective sleeve 20523 is d4, which is slightly larger than the outer diameter d3 of the auxiliary needle 2052, for example, relatively large 0.1-2mm, in order to facilitate the user to align the distal opening of the elastic protective sleeve 20523 and the auxiliary needle 2052. From the distal opening of the elastic protective sleeve 20523 to the proximal end, the inner diameter gradually decreases until it decreases to d5, which is slightly smaller than the outer diameter d3 of the auxiliary needle 2052, for example, relatively small 0.1-2mm. Since the material of the elastic protective sleeve 20523 has elasticity, 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 realize interference fit, increase the friction force 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 sleeved outside the auxiliary needle 2052 and will not fall off. That is, the elastic protective sleeve 20523 and the auxiliary needle 2052 are in size values, d4>d3>d5. The proximal end of the elastic protective sleeve 20523 can be open or closed, and the overall length thereof should be not less than the length h2 of the auxiliary needle 2052 exposed outside the shell 201, for example, relatively long 0.1-20mm, so that the elastic protective sleeve 20523 can completely wrap the exposed needle tip and realize the protection of the auxiliary needle 2052. Preferably, the proximal end of the elastic protective sleeve 20523 is closed, which can avoid 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 utility model, before the user uses the installation unit 200, the elastic protective sleeve 20523 can be a structural member independent of the installation unit 200, and after using the installation unit 200, the user sets the elastic protective sleeve 20523 on the auxiliary needle 2052 to form a whole with the installation unit 200.

[0186] In some embodiments of the utility model, since the elastic protective sleeve 20523 needs to have a certain elasticity to realize interference fit with the auxiliary needle 2052, the elastic protective sleeve 20523 can be made of elastic materials such as silica gel and rubber. Any change in the material of the elastic protective sleeve 20523 should be included in the protection scope of the utility model.

[0187] In some embodiments of the utility model, the elastic protective sleeve 20523 can not be limited to the straight bar structure shown in the above and Figures 18a-18c In some embodiments of the utility model, the elastic protective sleeve 20523 can not be limited to the straight bar structure shown in the above and

[0188] In the foregoing embodiments, after using the installation unit 200, the exposed needle tip needs to be protected by using an additional needle body protection structure, which increases the number of structural members of the installation unit 200, increases the design and processing cost, and for the user, it also increases the operation steps of using the installation unit 200, which is not conducive to user experience.

[0189] Figure 19a And Figure 19b The utility model parallel sliding block module as the schematic diagram of needle body protection structure.

[0190] Based on the above problems, referring to Figure 19a And Figure 19b In some embodiments of the utility model, in order not to increase the number of structural members of the installation unit 200, considering that the parallel sliding block module 203 itself is a necessary structural member of the installation unit 200, the parallel sliding block module 203 can be used as a protection structure of the auxiliary needle 2052. Details are described below.

[0191] In some embodiments of the utility model, referring to Figure 19a And Figure 19b The parallel sliding block module 203 includes a through hole 20323 for the auxiliary needle 2052 to pass through, and the through hole 20323 shares a central axis with the auxiliary needle 2052, so that the auxiliary needle 2052 can pass through the through hole 20323 to realize movement in the vertical direction relative to the parallel sliding block module 203.

[0192] In some embodiments of the utility model, as described above, when using the installation unit 200, the user abuts the skin surface with the shell 201, after triggering the installation unit 200, the elastic module pushes the parallel slider module 203 and the auxiliary needle module 205 to slide towards the proximal end 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, and at the same time, the auxiliary needle module 205 continues to move towards the proximal end relative to the shell 201 under the elastic force of the elastic module, so that the auxiliary needle 2052 penetrates into the subcutaneous tissue, and the in-vivo part of the sensor 2042 carried by the auxiliary needle 2052 enters the subcutaneous tissue. After that, the auxiliary needle 2052 retracts towards the distal end under the elastic force of the elastic module to exit the subcutaneous tissue, and when the auxiliary needle 2052 is completely retracted, at least a part 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, as shown in Figure 15 After the auxiliary needle 2052 is retracted, it no longer slides.

[0193] In some embodiments of the utility model, 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, the through hole 20323 can provide safety protection for the needle tip of the auxiliary needle 2052, and 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 shell 201 after retraction, for example, the exposed length of the auxiliary needle 2052 is h4, then the proximal end face of the through hole 20323 protrudes from the shell 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 utility model, before the user removes the installation unit 200, the first elastic member 2071 in the elastic module is still in a compressed state, and the parallel slider module 203 abuts the skin surface, so that a part of the elastic force of the first elastic member 2071 is not released. After the user removes the installation unit 200, since the parallel slider module 203 no longer abuts the skin surface, the first elastic member 2071 in the elastic module releases the elastic force and pushes the parallel slider module 203 to continue to slide towards the proximal end relative to the shell 201 until the parallel slider module 203 slides to the first predetermined position, at this time, the through hole 20323 of the parallel slider module 203 accommodates the needle tip of the auxiliary needle 2052, as shown in Figure 19a and Figure 19b Although the needle tip of the auxiliary needle 2052 protrudes from the shell 201, since the through hole 20323 of the parallel slider module 203 provides protection, the needle tip of the auxiliary needle 2052 will not cause unnecessary harm to the user.

[0195] In some embodiments of the present application, the inner diameter of the through hole 20323 is slightly larger than the outer diameter of the auxiliary needle 2052, so that the auxiliary needle 2052 can pass through.

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

[0197] In some embodiments of the present application, the through hole 20323 can be a funnel shape with the inner diameter decreasing from the distal end to the proximal end. The larger inner diameter at the distal end facilitates the entry of the auxiliary needle 2052 into the through hole 20323, and the smaller inner diameter at the proximal end can limit the swing of the auxiliary needle 2052, thereby ensuring the movement of the auxiliary needle 2052 in the vertical direction. After using the installation unit 200, the needle tip is accommodated in the proximal end of the through hole 20323 after the auxiliary needle 2052 is retracted.

[0198] In some embodiments of the present application, when the parallel slider module 203 is in the first predetermined position, the parallel slider module 203 is in a movable state relative to the housing 201, and is stopped by the first elastic member 2071 from retracting into the housing 201. However, after the user finishes using the installation unit 200, if the user accidentally presses the parallel slider module 203 and the force applied is greater than the elastic force of the first elastic member 2071, the first elastic member 2071 is compressed, and the parallel slider module 203 can be pushed into the housing 201, the needle tip of the auxiliary needle 2052 can be exposed, and there is still a possibility of causing unnecessary harm to the user. Therefore, after using the installation unit 200, it is necessary to fix the position of the parallel slider module 203 so that the parallel slider module 203 cannot 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 application, the outer side edge of the parallel slider module 203 is provided with a fixing structure, such as a fixed buckle 2031. When the parallel slider module 203 is in the first predetermined position, the fixed buckle 2031 is buckled connected on the inner side edge of the trigger module 206. After the user finishes using the installation unit 200, even if the user applies pressure to the parallel slider module 203, the parallel slider module 203 will not be retracted into the interior of the housing 201, and the through hole 20323 of the parallel slider module 203 can thus form a safe protection for the needle tip of the auxiliary needle 2052.

[0200] In some embodiments of the utility model, parallel slider module 203 is located inside shell 201 before using installation unit 200, fixed buckle 2031 is also located inside shell 201, in the process of using installation unit 200, with parallel slider module 203 being pushed to proximal end by first elastic piece 2071, fixed buckle 2031 is deflected in the direction of curved arrow as shown in Figure 19a And Figure 19b Shown, so that fixed buckle 2031 avoids interference with trigger module 206, affects normal use of installation unit 200.

[0201] In some embodiments of the utility model, fixed buckle 2031 needs to be deflected in the process of use, and also needs to restore to original form after deflection, fixed buckle 2031 can select material with certain elasticity, for example polypropylene, polyvinyl chloride, elastic metal piece etc.

[0202] In some embodiments of the utility model, the number of fixed buckle 2031 should be no less than 2, and is arranged at a certain distance apart on the outside edge of parallel slider module 203. Preferably, the number of fixed buckle 2031 is 3, and is arranged at equal distance apart on the outside edge of parallel slider module 203.

[0203] In some embodiments of the utility model, fixed buckle 2031 is integrally formed with parallel slider module 203, as shown in Figure 19a Or fixed buckle 2031 is a structural part independent of parallel slider module 203, and is fixed on parallel slider module 203 by welding, sticking, screw connection etc., as shown in Figure 19b .

[0204] In some embodiments of the utility model, buckle slider 2032 can also be arranged on the outside edge of parallel slider module 203, and correspondingly, buckle sliding groove 2011 is arranged on the inside of shell 201, and buckle slider 2032 can slide in buckle sliding groove 2011. By limiting buckle slider 2032 through buckle sliding groove 2011, on the one hand, parallel slider module 203 can be prevented from rotating in the process of moving to proximal end relative to shell 201, so that the position of parallel slider module 203 moves, and on the other hand, when parallel slider module 203 reaches the first predetermined position, by abutting buckle slider 2032 and trigger module 206, parallel slider module 203 can be prevented from being completely pushed out of shell 201 by first elastic piece 2071, causing parallel slider module 203 to fall off.

[0205] In some embodiments of the utility model, buckle sliding block 2032 can be integrally formed with fixed buckle 2031, and is located at the same position of the outer side edge of parallel sliding block module 203, so as to reduce the design and processing difficulty. In other embodiments of the utility model, buckle sliding block 2032 can also be arranged on the outer side edge of parallel sliding block module 203 independently of fixed buckle 2031, and the two are located at different positions of the outer side edge of parallel sliding block module 203, and are distributed on the outer side edge of parallel sliding block module 203 at a certain distance. Preferably, the number of buckle sliding block 2032 and fixed buckle 2031 is 3, and they are arranged at equal distances on the outer side edge of parallel sliding block module 203, that is, the interval angle of adjacent buckle sliding block 2032 and fixed buckle 2031 is 60°, and the interval angle of adjacent two buckle sliding blocks 2032 or adjacent two fixed buckles 2031 is 120°. In still other embodiments of the utility model, parallel sliding block module 203, buckle sliding block 2032 and fixed buckle 2031 are integrally formed, which can further reduce the design and processing difficulty.

[0206] In summary, the utility model discloses an analyte detection device installation unit, after using the installation unit, the through hole on the parallel sliding block module contains the needle tip of the auxiliary needle, and the parallel sliding block module is fixed relative to the trigger module through the fixed structure, so as to prevent the parallel sliding block module from retracting into the installation unit shell, the parallel sliding block module can provide effective safety protection for the auxiliary needle, and will not increase additional structural parts, and is also beneficial to the miniaturization design of the installation unit.
