Description

Technical Field

[0001] The present application relates to the technical field of blood glucose meters, and in particular to boosters, sensor consumables, blood glucose meters and working methods thereof. Background Art

[0002] Diabetics need to monitor their blood sugar levels for a long time. To achieve blood sugar monitoring, the sensor needs to be attached to the skin surface and the probe needs to be inserted into the human body. Since the probe is soft, a booster is often needed when attaching the sensor.

[0003] Common dynamic blood glucose meters include a sensor, a booster and a terminal, wherein the sensor and the booster are integrated. When in use, the booster is used to fit the sensor to the human body, wherein the steel needle of the booster is used to assist in inserting the probe into the human body. After use, the booster will be discarded because the steel needle is contaminated.

[0004] The sensor has a lifespan of about 7 to 14 days, after which the old sensor must be discarded and a new sensor attached, which in turn requires the discarding of a booster. The cost of using a blood glucose meter is relatively high. Summary of the invention

[0054] The present application provides a blood glucose meter, which may include a booster and a sensor consumable that are independently arranged and to be combined. Figure 1 and Figure 2 In an exemplary embodiment, the sensor 2 and the auxiliary needle 3 to be picked up by the booster 100 may be components of the sensor consumable 200 .

[0055] The sensor 2 and the auxiliary needle 3 can be used to assemble into a sensor module 20. The needle body 31 of the auxiliary needle 3 is inserted into the sensor 2 and used to support the probe 22. Figure 1 , a part of the auxiliary needle 3 can protrude from the top surface of the sensor 2 along the Z-axis direction. In order to measure blood sugar, the probe 22 of the sensor 2 needs to enter the human body, and the probe 22 is relatively soft, so the harder needle body 31 can ensure that the probe 22 has a good posture when entering the human body. The needle body 31 can at least half surround the probe 22 along the circumferential direction and is longer than the probe 22. The side of the sensor 2 where the probe 22 is located is the attachment surface 211, which can be attached to the skin surface, and then along the Z-axis direction, Figure 1 The lower side is shown as the proximal side and the upper side is shown as the distal side. The auxiliary needle 3 can be removed from the sensor 2 .

[0056] The present application provides a sensor consumable 200, which includes a sensor module 20 and a carrier box 6. The sensor module 20 includes a detachably connected sensor 2 and an auxiliary needle 3. Exemplarily, multiple sensor modules 20 or multiple groups of sensors 2 and auxiliary needles 3 can be arranged in the carrier box 6.

[0057] The sensor 2 includes a patch 21 and a probe 22. A chip 23 ( Fig.11 ), the probe 22 may be electrically connected to the chip 23. The attachment surface 211 of the attachment 21 may be adhesive, and the probe 22 protrudes from the attachment surface 211. Figure 2 and Figure 1 , the attachment 21 may have a substantially circular outer contour, and the position of the probe 22 in the XY plane may be closer to the edge relative to the center of the attachment 21, so that the position of the chip 23 in the attachment 21 may be close to the center, and the size of the attachment 21 may be small. The probe 22 may also be designed at other positions in the XY plane.

[0058] The auxiliary needle 3 is detachably connected to the sensor 2. In one embodiment, the auxiliary needle 3 and the sensor 2 are stored separately, and then can be assembled to the sensor 2 at the carrying box 6 when in use. The auxiliary needle 3 includes a needle body 31 for supporting the probe 22.

[0059] Exemplarily, the sensor module 20 includes a matching portion 201. Exemplarily, the sensor 2 may include the matching portion 201. In other embodiments, the matching portion 201 may be provided on the auxiliary needle 3. Exemplarily, the sensor 2 and the auxiliary needle 3 are both provided with the matching portion 201.

[0060] The carrying box 6 covers the attachment surface 211, the probe 22 and the needle body 31 and exposes the matching part 201. The carrying box 6 can protect and hold the sensor 2 and the auxiliary needle 3. The sensor consumable 200 can be matched with the booster 100. The sensor 2 and the auxiliary needle 3 can be removed from the carrying box 6 as a whole through the matching part 201. When the matching part 201 is set on the sensor 2, the picking is stable; when the matching part 201 is set on the auxiliary needle 3, the auxiliary needle 3 and the booster 100 are easy to separate.

[0061] In other embodiments, the mating portion 201 may be a ferromagnetic portion that can be attracted by a magnet, a threaded structure, or a surface area that can be connected by bonding, friction, vacuum adsorption, etc. In some embodiments, the carrier 6 can release the sensor module 20; and the booster 100 can be used from bottom to top, and then in the booster 100, the sensor module 20 can be restrained by its own gravity.

[0062] The sensor 2 can be attached to the human body using the booster 100, and then the booster 100 and the auxiliary needle 3 can be removed. The sensor 2 can realize the function of detecting blood sugar.

[0063] Exemplarily, the auxiliary needle 3 includes a needle handle 33. The needle handle 33 is connected to the needle body 31, and can be fixedly connected; it can also be rotatably connected, and the rotation axis can be parallel to the Z-axis direction. The needle handle 33 can be, for example, clamped on the attachment 21. The needle body 31 can be positioned relative to the attachment 21 by installing and positioning the needle handle 33 and the attachment 21. Figure 1 As shown, the needle handle 33 can be arranged on the upper side, i.e., the distal side, of the patch attachment 21. The needle handle 33 can be partially inserted into the patch attachment 21. The needle handle 33 can also be embedded in the patch attachment 21 like a button, and the upper surfaces of the two are, for example, flush, and the auxiliary needle 3 can be removed using the side structure.

[0064] In some embodiments, the auxiliary needle 3 includes a support member 32, which is connected to the needle body 31 and supported on a support surface 212 of the attachment 21 that faces away from the attachment surface 211. The support member 32 can be an integrated structure with the needle handle 33, or can be connected to the needle body 31 separately. The hollow interior of the support member 32 can reduce weight, and it is not limited to a shell, but can also be a plurality of support rods forming a cage. The support member 32 can be swingably connected to the needle handle 33, and when the support member 32 is in motion, the needle handle 33 and the needle body 31 can be ensured to be stable in the XY plane. The peripheral shape of the support member 32 can be designed to facilitate grasping by hand.

[0065] The diameter of the support member 32 can be smaller than the diameter of the attachment 21, and the support member 32 can be substantially aligned with the attachment 21. The support member 32 can cover the through hole at the probe 22, and then the needle body 31 is located inside the support member 32, and the needle body 31 is supported by the periphery to prevent shaking. The needle body 31 can be stably supported by the support member 32; when the support member 32 and the attachment 21 transmit thrust, the force transmission is relatively balanced.

[0066] The periphery of the sensor 2 is provided with a mating portion 201, and the mating portion 201 and the support member 32 define a preset installation dimension, and the booster 100 is configured with a corresponding installation dimension to pick up the sensor module 20. The dimension from the proximal end of the probe 22 to the distal end of the support member 32 may be the total length of the sensor module 20. In some embodiments, the periphery of the sensor 2 is provided with a plurality of mating portions 201 arranged at intervals, for example, three mating portions 201 distributed at 120°.

[0067] Combination Figure 3 and Figure 4 As shown, the carrier box 6 includes an indicator mark 601. When the booster 100 picks up the sensor 2, the matching portion 201 will be blocked inside. The indicator mark 601 is used to identify the circumferential position of the matching portion 201 so that the connecting portion 11 of the booster 100 is accurately connected to the corresponding matching portion 201, and the sensor 2 can be accurately taken out of the carrier box 6; in addition, the indicator mark 601 can also identify the position of the probe 22.

[0068] In an exemplary embodiment, the booster 100 includes a booster 1 and an operating assembly 10. The booster 1 can be mounted on the operating assembly 10 and has a proximal position and a distal position relative to the operating assembly 10 as a whole. Figure 1 As shown, the proximal-distal direction may be parallel to the Z-axis direction.

[0069] A accommodating cavity 101 is provided at the distal end of the booster 1. The accommodating cavity 101 is used to limit the sensor module 20. The booster 1 can limit the sensor module 20 by bonding, snapping, magnetic attraction, friction clamping, etc. The booster 1 can move from the proximal position to the distal position. Optionally, the booster 1 can limit the sensor module 20 at the proximal position, or at the distal position, or during the movement. The sensor 2 and the auxiliary needle 3 are arranged in sequence from the proximal end to the distal end. Specifically, the probe 22 extends out of the accommodating cavity 101, and the attachment surface 211 can be flush with or protrude from the booster 1. Exemplarily, the booster 1 can release the sensor module 20 when it is in the proximal position.

[0070] Exemplarily, the booster 1 includes a connecting portion 11 for detachably connecting to the sensor module 20. Figure 3As shown, optionally, the connecting portion 11 is used to connect to the matching portion 201 of the sensor 2 , and then clamp the auxiliary needle 3 in the accommodating cavity 101 .

[0071] Exemplarily, the booster 1 may be provided with a sensor receiving groove 102 and an auxiliary needle receiving groove 103 that are connected in sequence, the notch of the sensor receiving groove 102 faces the proximal side, and the diameter of the sensor receiving groove 102 may be larger than the diameter of the auxiliary needle receiving groove 103. The sensor receiving groove 102 and the auxiliary needle receiving groove 103 may be designed to be other shapes with larger sizes, respectively, the sensor receiving groove 102 can accommodate the sensor 2; the auxiliary needle receiving groove 103 can accommodate a part of the auxiliary needle 3 that is inserted through the sensor receiving groove 102.

[0072] refer to Figure 3 The booster 1 includes a booster plate 12, which can provide the bottom of the auxiliary needle receiving groove 103. The connecting portion 11 and the booster plate 12 clamp the sensor 2 and the auxiliary needle 3 along the Z-axis direction, and a part of the auxiliary needle 3 can be located in the sensor receiving groove 102. The support member 32 of the auxiliary needle 3 supports the support surface 212 of the attachment 21 of the sensor 2, and the support surface 212 of the sensor 2 does not contact the booster 1. The support member 32 transmits force, and when the operating component 10 drives the booster 1, it can not only synchronously control the sensor 2, but also ensure that the needle body 31 is subjected to the driving force to protect the probe 22.

[0073] In other embodiments, the sensor is slightly thicker, and the auxiliary needle can be completely sunken in the top surface of the sensor, and the support surface supporting the auxiliary needle may not be the top surface; the two are detachably connected to ensure that the auxiliary needle can be removed from the sensor. The sensor receiving slot receives the sensor module.

[0074] The operating assembly 10 is connected to the booster 1 and is used to drive the booster 1 from the distal position to the proximal position. The operating assembly 10 is also used to limit the booster 1 to the distal position. Figure 1 , the booster 1 is in the proximal position; Figure 3 In the embodiment, the booster 1 is at the distal position and is limited by the operating assembly 10 along the Z-axis direction, and the booster 1 can be moved from the proximal position to the distal position under the push of the sensor consumable 200. In other embodiments, the booster 1 can also be moved under the control of other external forces or the operating assembly 10, and then matched with the sensor module 20 of the sensor consumable 200.

[0075] refer to Figure 5 and Figure 6 , the operating assembly 10 can release the booster 1 in the distal position and drive the booster 1 from the distal position to the proximal position.

[0076] In some embodiments, the operating assembly 10 may include an operating mechanism and a driving mechanism, wherein the driving mechanism can drive the booster 1 from the distal position to the proximal position, and the operating mechanism can be used to restrict the booster 1 at the distal position and release the booster 1.

[0077] In other embodiments, the operating assembly 10 may include, for example, an electromagnet, which is a mechanism that can drive the booster 1 from the proximal position to the distal position, or from the distal position to the proximal position.

[0078] The operating assembly 10 may have a proximal end surface 401, such as Figure 6 As shown, when the booster 1 is driven to the distal position, the attachment surface 211 of the sensor 2 can be flush with or protrude from the proximal surface 401 , and the needle body 31 and the probe 22 protrude from the proximal surface 401 .

[0079] By providing the booster 1, the sensor 2 and the auxiliary needle 3 of the sensor module 20 can be boosted as a whole, and can be completely separated from the sensor module 20. The booster 100 can keep itself clean and pollution-free during operation, and can be used repeatedly, avoiding the waste of discarding after use.

[0080] refer to Figure 1 In some embodiments, the booster 1 includes a first engaging portion 13, and the operating assembly 10 includes a second engaging portion 41 and an operating portion 42. Figure 3 As shown, when the booster 1 is in the proximal position, the first engaging portion 13 is engaged with the second engaging portion 41, and the operating portion 42 is used to disengage the first engaging portion 13 from the second engaging portion 41. The operating assembly 10 can effectively limit the booster 1 and release the booster 1. The boosting action performed by the operating assembly 10 can push the sensor module 20 from the distal end to the proximal end, for example, the thrust acts on the auxiliary needle 3 and is transmitted to the sensor 2.

[0081] Exemplarily, the booster 1 may include at least two first engaging portions 13. The operating assembly 10 may include at least two second engaging portions 41, and different second engaging portions 41 may have different elastic directions. For example, the two second engaging portions 41 are arranged on both sides of the two first engaging portions 13 along the X-axis direction. Multiple sets of first engaging portions 13 and second engaging portions 41 help to improve the clamping stability of the operating assembly 10 on the booster 1.

[0082] The first engaging portion 13, the second engaging portion 41 and the operating portion 42 may constitute an operating mechanism, which is disposed along the Z-axis as a whole. The driving mechanism of the operating assembly 10 may be, for example, a spring 5. The operating mechanism is approximately at the central axis of the operating assembly 10, and the spring 5 may be sleeved outside the operating mechanism. In other embodiments, the operating mechanism may be offset or separated on both sides along the XY plane, and then the driving mechanism may be centrally located or offset.

[0083] like Figure 1 As shown, the first engaging portion 13 can be connected to the distal end of the boosting plate 12, and the first engaging portion 13 can extend substantially along the Z-axis direction. In some embodiments, the first engaging portion 13 is provided with a lateral bayonet 131, and the bayonet 131 can extend along the X-axis direction. The second engaging portion 41 includes a hook 411 adapted to the bayonet 131 to engage the first engaging portion 13. Figure 3 As shown, the hook 411 on the right side can extend into the slot 131 from the right side along the X-axis direction, and the lateral slot 131 effectively limits the hook 411 along the distal and proximal directions.

[0084] The operating part 42 can control the second engaging part 41 to release the first engaging part 13. The second engaging part 41 has a controlled surface 412, which is a surface of the second engaging part 41 facing the first engaging part 13 along the X-axis direction. The operating part 42 is movable relative to the second engaging part 41, and the operating part 42 can press the controlled surface 412 to disengage the hook 411 from the bayonet 131.

[0085] like Figure 1 As shown, in the XZ plane, the controlled surface 412 is inclined relative to the Z-axis direction. The two controlled surfaces 412 can form a trapezoid that is larger at the top and smaller at the bottom, and the position of the controlled surface 412 can be on the upper side of the hook 411. When the operating part 42 moves downward, it will squeeze the controlled surfaces 412 on both sides, causing the two hooks 411 to expand and pull out of the bayonet 131. In other embodiments, the operating part 42 can be a swinging dial that can swing downward; the operating part 42 can be a horizontal button that abuts against the controlled surface 412. The operating part 42 that is pressed along the Z-axis direction has a simple structure and is easy to assemble, and the pressing action is consistent with the driving direction of the booster 1. The booster 100 has good operating performance and a good operating feel, which is conducive to the smart implantation of the probe 22.

[0086] In some embodiments, the operating assembly 10 includes a guide tube 4. The guide tube 4 may have a proximal end surface 401, which also serves as the end surface of the operating assembly 10. The guide tube 4 is sleeved on the booster 1 and defines the moving direction of the booster 1 between the distal position and the proximal position. Figure 3 and Figure 5 When the booster 1 is at the distal position, the probe 22 of the sensor 2 is retracted into the proximal surface 401 of the guide tube 4 along the Z-axis direction. Before the boost, the guide tube 4 can protect the probe 22; during the boost, the booster 1 moves stably.

[0087] The driving mechanism can drive the booster 1 to move relative to the guide cylinder 4. For example, the operating assembly includes a spring 5 disposed between the guide cylinder 4 and the booster 1. Exemplarily, the spring 5 is a compression spring, the upper end of which abuts against the bottom of the guide cylinder 4, and the lower end of which can abut against the booster plate 12 of the booster 1, and can push the booster 1 along the Z-axis direction. The outer periphery of the booster plate 12 of the booster 1 can have an upward flange to constrain the spring 5 in the XY plane. The structure of the constrained compression spring is simple.

[0088] In other embodiments, the spring 5 may be a tension spring, which is, for example, sleeved outside the booster 1 , with its lower end fixed to the guide tube 4 and its upper end fixed to the distal end of the booster 1 .

[0089] Optionally, the second engaging portion 41 is integrally formed with the guide tube 4 , and the root of the second engaging portion 41 is connected to the bottom of the guide tube 4 and can be elastically deformed. The second engaging portion 41 can also be a part assembled to the guide tube 4 .

[0090] Exemplarily, the operating portion 42 protrudes from the guide cylinder 4 along the Z-axis direction, and the operating portion 42 may include a pressing cap to facilitate pressing operation. Exemplarily, the operating portion 42 includes a control end for abutting against the controlled surface 412 and a guide section connected to the control end. An operating cylinder section may be provided between the second engaging portion 41 and the guide cylinder 4, and the operating cylinder section cooperates with the guide section of the operating portion 42 to ensure that the operating portion 42 moves in the distal and proximal directions.

[0091] When the booster 100 presses the sensor consumable 200, the booster 1 can be limited to the distal position first, or the booster 1 can be pressed from the proximal position to the distal position by the reverse thrust of the auxiliary needle 3 and the sensor 2 and trigger the limit of the operating assembly 10. When the booster 1 is in the distal position, it is retracted into the guide tube 4, and relatively speaking, the proximal surface 401 of the guide tube 4 is far away from the proximal end of the booster 1. For example, the carrier box 6 can be designed to avoid the proximal end of the guide tube 4.

[0092] The carrier box 6 includes a carrier platform 61 and a guide groove 62. The carrier platform 61 carries the sensor 2, covers the needle body 31, and the probe 22, and avoids the matching portion 201 on the side. The guide groove 62 at least partially surrounds the carrier platform 61, and the guide groove 62 can be adapted to the guide cylinder 4 so that the booster 100 can be smoothly matched into the sensor consumable 200. The indicator mark 601 can be located on the periphery of the guide groove 62, such as the upper surface of the peripheral flange, so that it can be observed easily.

[0093] like Figure 1 and Figure 3As shown, the booster 1 is provided with a sensor receiving groove 102 and an auxiliary needle receiving groove 103 which are connected in sequence, and the notch of the sensor receiving groove 102 can face the proximal side. A plurality of connecting parts 11 arranged at intervals along the circumference are provided at the sensor receiving groove 102, for example, three connecting parts 11 at intervals of 120°. The connecting part 11 cooperates with the groove bottom of the auxiliary needle receiving groove 103 to clamp the sensor module 20. The operating component 10 includes an alignment mark 402 for identifying the circumferential position of the connecting part 11. For example, the alignment mark 402 can be provided on the outer wall of the guide tube 4. Figure 2 and Figure 4 , the alignment mark 402 can be aligned with the indicator mark 601, the corresponding connecting portion 11 is connected to the matching portion 201, the booster 1 can more accurately assemble the sensor 2 and the auxiliary needle 3, and also help to determine the position of the probe 22, refer to Figures 6 to 8 The alignment mark 402 helps to more accurately control the position of the probe 22 during the boost.

[0094] refer to Fig.11 The present application provides a blood glucose meter 400. The blood glucose meter 400 includes a sensor module 20 and a booster 100, and specifically, may include multiple sets of sensors 2 and auxiliary needles 3.

[0095] The booster 100 can pick up, for example, a set of sensors 2 and auxiliary needles 3 and is used to attach the sensor 2 to the skin to detect blood sugar. The sensor module 20 can be taken out from the sensor consumables 200 by the booster 100. Using the sensor consumables 200 including the carrying box 6, the booster 100 can accurately pick up the sensor module 20.

[0096] The sensor module 20 includes a mating portion 201, and the booster 100 used to connect and release the sensor module 20 can be used repeatedly, so that the use cost of the blood glucose meter 400 is low and waste is reduced. The sensor 2 includes an attachment 21 and a probe 22 protruding from an attachment surface 211 of the attachment 21. When the auxiliary needle 3 is connected to the sensor 2, the needle body 31 is used to support the probe 22. When the sensor 2 detects blood glucose, the auxiliary needle 3 can be removed from the sensor 2.

[0097] The blood glucose meter 400 also includes a terminal 300, which is connected to the sensor 2 by communication, such as wireless communication or data cable. The terminal 300 can process the data of the sensor 2, such as displaying or alarming. The terminal 300 can be a mobile phone, a computer, a smart watch, etc.

[0098] refer to Fig.12 The present application provides a working method 1000 of a blood glucose meter, which may include steps S101 to S104. When using the sensor consumable 200, the working method 1000 of the blood glucose meter may also include steps S105 to S107. Figures 1 to 11 The working method 1000 of the blood glucose meter of the present application is described in detail.

[0099] Step S101, setting the booster 1 in the blood glucose meter 400 to the distal position. The accommodating cavity 101 of the booster 1 is equipped with a sensor module 20, which includes a sensor 2 and an auxiliary needle 3 arranged in sequence from the proximal end to the distal end. Optionally, the booster 1 can be placed in the distal position first and then accommodate the sensor 2 and the auxiliary needle 3; or the sensor 2 and the auxiliary needle 3 can be accommodated first.

[0100] Combination Figure 1 Exemplarily, step S105 is performed before step S101 to accommodate the sensor module 20 using the booster 1 in the proximal position.

[0101] Step S106, by aligning the alignment mark 402 of the booster 100 for identifying the circumferential position of the connecting portion 11 with the indicator mark 601 of the sensor consumable 200 for identifying the circumferential position of the matching portion 201, the booster 1 is accurately aligned with the sensor module 20, such as Figure 3 As shown, the connecting portion 11 is accurately connected to the matching portion 201, and the position of the probe 22 can be accurately analyzed, thereby improving work efficiency.

[0102] Step S107, using the booster 100 to remove the sensor module 20 from the sensor consumable 200, such as Figure 5 shown.

[0103] Step S102: In response to the driving of the operating assembly 10, the booster 1 moves from the distal position to the proximal position, and drives the sensor module 20. After the booster 1 is located at the proximal position, the booster 100 is as follows: Figure 6 shown.

[0104] When using the blood glucose meter 400, Figure 5 The booster 100 in the shown state is placed on the detection area on the skin where blood sugar can be measured, and the proximal surface 401 can be attached to the skin. Then the operating part 42 is pressed so that the booster 1 is no longer restricted. Then the spring 5 can drive the booster 1, the auxiliary needle 3 and the sensor 2, and the probe 22 supported by the needle body 31 can penetrate the detection area, and the attachment surface 211 can be attached to the skin surface.

[0105] Step S103, the booster 1 releases the sensor module 20. For example, the connecting portion 11 is disengaged from the mating portion 201 to disengage the booster 100 from the sensor module 20. Figure 7 and Figure 8 The connecting portion 11 may be elastic and can be bounced out of the matching portion 201 .

[0106] The booster 100 can be removed after boosting the sensor module 20, and can be used repeatedly thereafter, for example, a new sensor 2 can be replaced every 7 to 14 days. The blood glucose meter 400 can continue to work effectively. The booster 100 can effectively control the probe 22 to move in place along the Z-axis direction. The booster 100 can avoid being contaminated.

[0107] Step S104: After step S103, the auxiliary needle 3 is disassembled from the sensor 2. Fig. 9 and Fig.10 The auxiliary needle 3 can be discarded. The working method of the blood glucose meter 400 provided in the present application is simple to implement.
