Description

Technical Field

[0001] This invention relates to the field of blood glucose measurement device technology, and more specifically to a reusable patch that prevents accidental activation. Background Technology

[0002] Diabetes is a common chronic disease in modern society. It is caused by a combination of factors, including obesity, stress, poor dietary habits, and genetic predisposition, resulting in an absolute or relative deficiency of insulin production by the pancreas. This deficiency fails to correct the imbalance of glucose in the blood, leading to an absolute increase in blood sugar levels. Blood normally contains a certain concentration of glucose, from which tissue cells obtain energy. However, when glucose levels rise excessively, it cannot be properly stored in the liver, muscles, or fat cells, accumulating in the blood. Therefore, the blood sugar levels of diabetic patients are maintained much higher than normal. As excess glucose is directly excreted through tissues and then through urine, the body's tissues become deficient in the necessary glucose, leading to abnormalities in various tissues.

[0003] In the prior art, a blood glucose meter includes a sensor module that is inserted into the skin of the body and measures blood glucose from bodily fluids, a transmitter that transmits the blood glucose value measured by the sensor module to a terminal, and a terminal that outputs the received blood glucose value. The sensor module includes a sensor probe shaped like a needle that is inserted into subcutaneous fat to extract intercellular fluid. An applicator is generally used to insert the sensor module into the body.

[0004] However, existing applicators have the following drawbacks:

[0005] 1. Some existing blood glucose meter patches are for single use only and cannot be reused;

[0006] 2. Existing blood glucose meter patch devices are complex to operate and not easy to use;

[0007] 3. Some existing blood glucose meter patches do not have an anti-accidental touch function; pressing the button directly unlocks the needle. Summary of the Invention

[0008] The purpose of this invention is to provide a reusable and accident-proof applicator with a simple internal structure, easy assembly, and the ability to be reset and reused, thus preventing accidental contact and making the applicator safer to use.

[0009] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0010] A reusable applicator designed to prevent accidental activation includes an applicator housing with a downward applicator opening, a linkage-driven needle ejector device disposed within the applicator housing, and a transmitter assembly for cooperating with the linkage-driven needle ejector device. The linkage-driven needle ejector device drives the transmitter assembly to move along the applicator opening direction to generate needle ejection and ejection actions.

[0011] Furthermore, the dressing housing includes a left shell and a right shell that overlap each other, forming a cavity between the left and right shells. The connecting rod needle pusher and needle retraction device is disposed in the cavity. The left shell is provided with a release component and an anti-accidental contact component that cooperate with the connecting rod needle pusher and needle retraction device. The right shell is provided with a reset component that cooperates with the connecting rod needle pusher and needle retraction device.

[0012] Furthermore, a first torsion spring groove is provided on the inner side of the left shell. The connecting rod push-pin and retract-pin device includes a rotating shell rotatably arranged coaxially with the first torsion spring groove. A second torsion spring groove is provided on the side of the rotating shell near the first torsion spring groove. It also includes a torsion spring assembled between the first torsion spring groove and the second torsion spring groove. The distal end of the rotating shell is rotatably connected to one end of the first connecting rod, and the other end of the first connecting rod is rotatably connected to the second connecting rod. The inner middle of the left and right shells facing each other is symmetrically provided with sliding grooves that cooperate with the second connecting rod. The two sliding grooves are connected to each other to form a guide hole that allows the second connecting rod to slide up and down. The second connecting rod moves vertically through the guide hole. The lower end of the second connecting rod is detachably connected to a transmitter assembly retainer. The torsion spring force of the torsion spring drives the rotating shell to rotate 180°, thereby driving the first connecting rod and the second connecting rod to drive the transmitter assembly to push and retract the pin.

[0013] Furthermore, the reset assembly includes a reset knob rotatably mounted on the right shell. The inner side of the reset knob is coaxially fixed with the rotation axis of the rotating shell. When the reset knob is rotated to the power storage position, the torsion spring stores the torsion spring potential energy.

[0014] Furthermore, the release assembly includes a release button that can be pressed on the left shell. A pressing spring is abutted between the release button and the left shell. A limiting rib that can extend into the cavity and cooperate with the rotating shell is provided on the inner side of the release button. A stop block is provided perpendicularly to the inner side of the limiting rib. A rib position that cooperates with the stop block is provided on the rotating shell. When the rotating shell is in the power storage position, the stop block and the rib position are in a vertical stop cooperation. An clearance opening is formed on the rear side of the rib position. When the release button is pressed, the stop block moves to directly below the clearance opening, the rib position loses its stopping function, and the rotating shell rotates by ° through the potential energy of the torsion spring.

[0015] Furthermore, the anti-accidental touch component includes an unlocking push button located on the side of the left shell. The inner side of the unlocking push button is vertically provided with a locking rib that can be moved into the cavity and cooperate with the rotating shell. The inner side of the locking rib forms a locking position. The rotating shell has a locking position corresponding to the locking position. When the rotating shell is in the power-up position, the locking position and the locking position are horizontally opposed to each other, and the rotating shell cannot rotate. When the unlocking push button is pushed down, the locking position disengages from the locking position. When the release button is pressed, the rotating shell rotates 180° by the potential energy of the torsion spring.

[0016] Furthermore, according to the claim 1, a reusable patch for preventing accidental contact is characterized in that the transmitter assembly includes a detector, a guide pin that is movably connected to the detector, and the bottom of the detector is provided with adhesive tape for adhering to human skin.

[0017] Furthermore, the transmitter assembly retainer includes a connecting rod portion detachably connected to the second connecting rod and a claw disc portion snapped together with the transmitter assembly. The connecting rod portion is symmetrically provided with a rotating slot in the horizontal direction, and a mounting slot is vertically connected to the inner side of the rotating slot. The bottom end of the second connecting rod is symmetrically provided with a retaining shaft, and a retaining ridge is provided in the rotating slot. The second connecting rod extends movably into the mounting slot through the retaining shaft, and the claw disc portion is rotated so that the retaining shaft passes through the retaining ridge to form a fixed installation.

[0018] The inner side of the connecting rod portion has a plurality of inner claws for engaging the guide pin, and the upper part of the guide pin has an engaging portion;

[0019] The bottom periphery of the claw disk is provided with several vertically downward claws, and the periphery of the detector is provided with micro-slots corresponding to the claw positions. When the transmitter assembly is assembled, the claws are clamped and fixed with the micro-slots. The claw disk is provided with several disassembly holes running vertically through it.

[0020] Furthermore, it also includes an auxiliary disassembly and assembly component used in conjunction with the applicator. The diameter of the auxiliary disassembly and assembly component is adapted to the diameter of the applicator opening. The auxiliary disassembly and assembly component has a disassembly and assembly groove formed on it. Disassembly and assembly claws are symmetrically arranged in the disassembly and assembly groove. The auxiliary disassembly and assembly component extends into the applicator opening, and the disassembly and assembly claws engage in the disassembly and assembly groove.

[0021] Furthermore, it also includes a replenishment box for use with the applicator, the replenishment box having a loading space for loading the transmitter assembly, and a replenishment cover that screws onto the replenishment box, the replenishment cover having a sealing gasket inside.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] This invention's applicator utilizes a crank-connecting rod principle to complete the needle pushing and retracting actions, with a torsion spring acting as a connecting rod to provide power. Adding positioning and unlocking buttons allows the torsion spring to be tortuously positioned. When the button is unlocked, the torsion spring rotates back to its original position, driving the connecting rod to automatically push and retract the needle. This invention allows the connecting rod needle pushing and retracting mechanism to be directly reset to its unused state via a reset knob, without the need for other auxiliary parts. The applicator can be disassembled using an auxiliary disassembly and assembly component to remove the locking guide needle. After removing the guide needle, the component can be reinstalled into the applicator to install a new transmitter assembly, achieving the applicator's reusability. An anti-accidental button function is implemented to prevent accidental button presses that could lead to waste or damage to the applicator. Attached Figure Description

[0041] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0042] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0043] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0044] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first and second features are in direct contact, or that they are in indirect contact through an intermediate medium. Furthermore, "above," "over," and "on top" of the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0045] like Figure 1-13 As shown, a reusable patch that prevents accidental contact includes a patch housing with a downward patching opening 103, a linkage pusher and retractor device disposed within the patch housing, and a transmitter assembly for cooperating with the linkage pusher and retractor device. The linkage pusher and retractor device drives the transmitter assembly to move along the patching opening 103 to form pusher and retractor actions.

[0046] Specifically, as shown in the figure, the dressing housing includes a left shell 1 and a right shell 2 that overlap each other, forming a cavity between the left shell 1 and the right shell 2. The connecting rod needle pusher and needle retraction device is disposed in the cavity. The left shell 1 is provided with a release component and an anti-accidental contact component that cooperate with the connecting rod needle pusher and needle retraction device. The right shell 2 is provided with a reset component that cooperates with the connecting rod needle pusher and needle retraction device.

[0047] Specifically, as shown in the figure, the inner side of the left shell 1 is provided with a first torsion spring groove 101. The connecting rod needle pushing and retracting device includes a rotating shell 6 coaxially and rotatably disposed with the first torsion spring groove 101. The rotating shell 6 is provided with a second torsion spring groove on the side near the first torsion spring groove 101. It also includes a torsion spring 5 assembled between the first torsion spring groove 101 and the second torsion spring groove. The distal end of the rotating shell 6 is rotatably connected to one end of the first connecting rod 8, and the other end of the first connecting rod 8 is rotatably connected to the second connecting rod 9. The left shell... 1. On the inner side of the right shell 2, there are symmetrically arranged sliding grooves 102 that cooperate with the second connecting rod 9. The two sliding grooves 102 are connected to each other to form a guide hole that allows the second connecting rod 9 to slide up and down. The second connecting rod 9 moves vertically through the guide hole. The lower end of the second connecting rod 9 is detachably connected to the transmitter assembly retainer 10. The torsion spring force of the torsion spring 5 drives the rotating shell 6 to rotate 180°, thereby driving the first connecting rod 8 and the second connecting rod 9 to drive the transmitter assembly to perform the push and pull needle actions.

[0048] Specifically, as shown in the figure, the reset assembly includes a reset knob 18 rotatably mounted on the right shell 2. The inner side of the reset knob 18 is coaxially fixed with the rotation axis of the rotating shell 6. When the reset knob 18 is rotated to the power storage position, the torsion spring 5 stores the torsion spring potential energy.

[0049] Specifically, as shown in the figure, the release assembly includes a release button 3 pressed on the left shell 1. A pressing spring 4 is abutted between the release button 3 and the left shell 1. A limiting rib 31 is provided on the inner side of the release button 3, which can be moved into the cavity and cooperate with the rotating shell 6. A stop block 32 is provided perpendicularly to the inner side of the limiting rib 31. A bone position 603 is provided on the rotating shell 6 to limit and cooperate with the stop block 32. When the rotating shell 6 is in the power storage position, the stop block 32 and the bone position 603 are engaged in vertical stop cooperation. An avoidance opening 602 is formed on the rear side of the bone position 603. When the release button 3 is pressed, the stop block 32 moves to directly below the avoidance opening 602, the bone position 603 loses its stopping function, and the rotating shell 6 rotates 180° by the potential energy of the torsion spring.

[0050] Specifically, as shown in the figure, the anti-accidental touch component includes an unlocking push button 7 disposed on the side of the left shell 1. The inner side of the unlocking push button 7 is provided with a locking rib 71 that can be moved into the cavity and cooperate with the rotating shell 6. The inner side of the locking rib 71 forms a locking position 711. The rotating shell 6 forms a locking position 601 corresponding to the locking position 711. When the rotating shell 6 is in the power-up position, the locking position 711 and the locking position 601 are horizontally opposed to each other, and the rotating shell 6 cannot rotate. When the unlocking push button 7 is pushed down, the locking position 711 disengages from the locking position 601. When the release button 3 is pressed, the rotating shell 6 rotates 180° by the potential energy of the torsion spring.

[0051] Specifically, as shown in the figure, the transmitter assembly includes a detector 12 and a guide pin 11 that is movably connected to the detector 12. The bottom of the detector 12 is provided with adhesive tape 13 for adhering to human skin.

[0052] Specifically, as shown in the figure, the transmitter assembly holder 10 includes a connecting rod portion 1001 detachably connected to the second connecting rod 9 and a claw plate portion 1002 snapped together with the transmitter assembly. The connecting rod portion 1001 is symmetrically provided with a rotating groove 1005 in the horizontal direction. The rotating groove 1005 is vertically connected to an installation groove 1006 in the inner side. The bottom end of the second connecting rod 9 is symmetrically provided with a retaining shaft 91. The rotating groove 1005 is provided with a retaining ridge 1007. The second connecting rod 9 extends movably into the installation groove 1006 through the retaining shaft 91. Rotating the claw plate portion 1002 causes the retaining shaft 91 to pass through the retaining ridge 1007 to form a fixed installation.

[0053] The inner side of the connecting rod portion 1001 is formed with a plurality of inner claws 1008 for engaging the guide pin 11, and the upper part of the guide pin 11 is formed with an engaging portion 111;

[0054] The bottom periphery of the claw disk 1002 is provided with several vertically downward claws 1004. The periphery of the detector 12 is provided with micro-slots corresponding to the positions of the claws 1004. When the transmitter assembly is assembled, the claws 1004 are clamped and fixed with the micro-slots. The claw disk 1002 is provided with several disassembly holes 1003 running vertically through it.

[0055] Specifically, such as Figure 14 As shown, it also includes an auxiliary disassembly and assembly component 14 for use with the applicator. The diameter of the auxiliary disassembly and assembly component 14 is adapted to the diameter of the applicator opening 103. The auxiliary disassembly and assembly component 14 has a disassembly and assembly groove 141. Disassembly and assembly claws 142 are symmetrically arranged in the disassembly and assembly groove 141. The auxiliary disassembly and assembly component 14 extends into the applicator opening 103, and the disassembly and assembly claws 142 are engaged in the disassembly and assembly groove 141.

[0056] Specifically, such as Figure 15 As shown, it also includes a replenishment box 15 for use with the applicator, the replenishment box 15 having a loading space for loading the transmitter assembly, and a replenishment cover 16 that screws onto the replenishment box 15, the replenishment cover 16 having a sealing gasket 17 disposed inside.

[0057] Specifically, the specific usage process of this invention is as follows:

[0058] 1. Before use, take the applicator out of the packaging and use its application opening 103 to contact the sterilized skin. First, push the unlocking push button 7 on the side of the applicator downward. At this time, the locking position 711 disengages from the position 601, that is, the unlocking push button 7 is in the unlocked position, and the locking position 711 can no longer restrict the rotation of the rotating shell 6. At this time, press the release button 3. During the pressing process, the limiting rib 31 moves inward, that is, the stop block 32 moves inward, so that the stop block 32 moves directly below the clearance opening 602. The bone position 603 loses its stopping function. Since the torsion spring 5 is in the stored state, the unrestricted rotating shell 6 rotates 180° counterclockwise. During the rotation, the clearance opening 602 can pass through the stop block 32 without obstruction.

[0059] During the 180° counterclockwise rotation, the first 90° is the needle pushing action and the last 90° is the needle retraction action, as follows: When the rotating shell 6 rotates 90° counterclockwise, it drives the first connecting rod 8 to push the second connecting rod 9 downward, thereby moving the transmitter assembly downward to the application opening 103 position. The guide needle 11 pierces the human skin, and the sensor's monitoring electrode is inserted under the skin to achieve real-time blood glucose monitoring. At this time, the adhesive tape 13 is placed at the bottom of the detector 12 and adheres tightly to the human skin. When the rotating shell 6 continues to rotate counterclockwise from 90° to 180°, the first connecting rod 8 pulls the second connecting rod 9 upward, thereby moving the transmitter assembly retainer 10 and the guide needle 11 upward. The detector 12 detaches from the transmitter assembly retainer 10 and adheres firmly to the skin surface, completing the needle retraction action.

[0060] 2. After completing one application process, the device needs to be disassembled for convenient use next time. The specific disassembly process is as follows: The auxiliary disassembly component 14 is inserted into the application opening 103 and its disassembly claw 142 is engaged in the disassembly hole 1003. The auxiliary disassembly component 14 is rotated clockwise, thereby driving the transmitter assembly retainer 10 to rotate. The retaining shaft 91 is released from the retaining edge restriction of the rotating slot 1005, and the transmitter assembly retainer 10 can be removed vertically downward along the installation vertical groove 1006. After removing the transmitter assembly retainer 10, the guide pin 11 engaged in the inner claw 1008 is manually removed, and the transmitter assembly retainer 10 is reinstalled according to the above principle.

[0061] 3. After the needle removal is completed, for convenient use next time, the device needs to be reset. The specific reset principle is as follows: Press the release button so that the clearance 602 is aligned with the stop block 32. Rotate the reset knob 18 clockwise to the power storage position. The torsion spring 5 stores the torsion spring potential energy. Release the release button. The stop block 32 and the bone position 603 are engaged in upper and lower stop. At this time, by pushing the unlocking push button 7 upward, the locking position 711 is abutted against the position 601, thereby realizing the anti-accidental touch function.

[0062] 4. After resetting, the applicator needs to be replenished. The specific replenishment process is as follows: Remove the replenishment cover 16 of the replenishment box 15 by thread and insert the replenishment box 15 into the applicator opening 103 so that the guide pin locking part 111 is locked into the inner claw 1008. At the same time, the micro-slot on the periphery of the detector 12 is locked with the claw 1004. At this time, the replenishment box 15 can be removed to complete the replenishment operation.

[0063] This invention's applicator utilizes a crank-connecting rod principle to complete the needle pushing and retracting actions, with a torsion spring acting as a connecting rod to provide power. Adding positioning and unlocking buttons allows the torsion spring to be tortuously positioned. When the button is unlocked, the torsion spring rotates back to its original position, driving the connecting rod to automatically push and retract the needle. This invention allows the connecting rod needle pushing and retracting mechanism to be directly reset to its unused state via a reset knob, without the need for other auxiliary parts. The applicator can be disassembled using an auxiliary disassembly and assembly component to remove the locking guide needle. After removing the guide needle, the component can be reinstalled into the applicator to install a new transmitter assembly, achieving the applicator's reusability. An anti-accidental button function is implemented to prevent accidental button presses that could lead to waste or damage to the applicator.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.

[0065] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
