Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and particularly to an insulin pump reservoir with an installation feedback function. Background Art

[0002] The insulin pump reservoir is a key component of an insulin pump and is a container specifically for storing insulin. It is mainly used to accurately and quantitatively store and supply insulin for diabetic patients to simulate the physiological insulin secretion mode of the human pancreas. During the treatment of diabetes, the insulin pump is connected to the reservoir and, according to the patient's preset basal infusion rate and the large-dose requirement during meals, infuses the insulin in the reservoir into the patient's body on time and accurately, helping the patient effectively control blood sugar levels, improve the patient's quality of life, and maintain good health.

[0003] In the prior art, it is difficult for users to intuitively judge whether the reservoir is installed in place. After the traditional insulin pump reservoir is installed, there is no obvious and intuitive way to inform the user whether the installation is successful. Users can only rely on experience or trial operations to confirm, which is prone to misjudgment. Since the installation status cannot be accurately known, insulin cannot be normally infused or the infusion dose is inaccurate, affecting the patient's blood sugar control and posing potential risks to the patient's health. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides an insulin pump reservoir with an installation feedback function, which solves the problem that it is difficult to intuitively feel whether the reservoir is successfully installed in the existing reservoir, affecting subsequent use.

[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: An insulin pump reservoir with an installation feedback function includes an insulin pump body. A mounting box is fixedly connected to the left side of the insulin pump body. A mounting ring is fixedly connected to the front side of the mounting box. Two second sliding rods are fixedly connected between the top and bottom of the inner wall of the mounting box. Two color plates are slidably connected between the two second sliding rods. A second spring is fixedly connected between the top of the upper color plate and the mounting box. A moving rod is fixedly connected between the two color plates. The left side of the moving rod penetrates and extends into the mounting ring. A liquid storage tube is arranged inside the insulin pump body. Two mounting blocks are fixedly connected to the surface of the liquid storage tube. Limiting grooves are formed on the surfaces of the two mounting blocks. A piston is slidably connected to the inner diameter of the liquid storage tube. A connecting piece is fixedly connected to the left end of the liquid storage tube. A fixing component is arranged inside the mounting box, and the fixing component is used to fix the liquid storage tube.

[0006] Preferably, the fixing component includes a first sliding rod fixedly connected between the first sliding rod and the mounting box. A locking block is slidably connected to the surface of the first sliding rod. The left side of the locking block penetrates and extends to the inner diameter of the mounting ring. A first spring is fixedly connected between the rear side of the locking block and the mounting box. A pressing rod is arranged on the top of the locking block, and the pressing rod is slidably connected to the mounting box.

[0007] Preferably, a connection box is fixedly connected to the inner wall of the connecting piece. A gear is rotatably connected to the rear side of the inner wall of the connection box. A rotating rod is fixedly connected to the front end of the gear. A sealing plate is fixedly connected to the surface of the rotating rod, and the sealing plate is in close fit with the connecting piece.

[0008] Preferably, a locking member is slidably connected to the right side inside the connection box. The locking member is meshed with the gear. A third spring is fixedly connected between the top of the locking member and the connection box. A rack is slidably connected to the bottom of the inner wall of the connection box. A fourth spring is fixedly connected between the right side of the rack and the connection box. The rack is meshed with the gear.

[0009] Preferably, a pressing block is slidably connected to the front side of the connecting piece. Two connecting rods are rotatably connected to the rear side of the pressing block. Moving members are rotatably connected to the rear sides of the two connecting rods. A fifth spring is fixedly connected between the rear side of the pressing block and the connecting piece.

[0010] Preferably, a mounting disc is arranged on the left side of the connecting piece. A trigger rod is fixedly connected to the right side of the mounting disc. Two fixing grooves are formed on the right side of the mounting disc.

[0011] Preferably, an infusion tube is fixedly connected to the left end of the mounting disc, and a connector is fixedly connected to the bottom end of the infusion tube.

[0012] Preferably, a chute is formed in the inner diameter of the mounting ring, and a rectangular groove is formed on the left side of the mounting box. The rectangular groove is located on the left side of the color plate.

[0014] Preferably, the right end of the trigger rod penetrates and extends into the connection box, and the trigger rod is slidably connected to the connection box.

[0015] Working principle: the user first inserts the liquid storage tube into the insulin pump body and rotates the liquid storage tube, which drives the installation block to rotate in the installation ring. The installation block pushes the moving rod upward, which in turn drives the color plate to move along the second slide bar. The user observes the color of the color plate through the rectangular groove of the installation box to judge the installation progress. At the same time, when the liquid storage tube rotates 90 degrees, the first spring pushes the locking block to insert into the limit groove of the installation block to lock the liquid storage tube. During installation, the user will feel a stuck feeling in the hand and hear a sound. When disassembling, press the pressing rod to make the locking block disengage from the limit groove, and rotate the liquid storage tube to remove it.

[0016] The mounting plate is pressed onto the connector, the trigger rod is inserted into the connector box, the rack is pushed to move, the locking part is disengaged from the gear, the rack then meshes with the gear to drive it to rotate, and then the rotating rod and the sealing plate are rotated to open the liquid outlet. The mounting plate and the connector are fixed by the moving part and the fixing groove. When removing the mounting plate, the pressing block is pressed to drive the moving part to disengage from the fixing groove through the connecting rod, the trigger rod is disengaged from the connector box, and each component is reset to close the liquid outlet. The infusion tube at the left end of the mounting plate is connected to the patient's subcutaneous indwelling needle through the connector to achieve insulin delivery.

[0017] The present invention provides an insulin pump medicine storage device with an installation feedback function. It has the following beneficial effects:

[0018] 1. The present invention inserts the liquid storage tube into the insulin pump body and rotates it. At this time, the liquid storage tube drives the mounting block to rotate in the mounting ring. The mounting block presses the moving rod to move upward during rotation. The moving rod drives the two color plates to move. When not installed, the top color plate is pressed by the second spring to be exposed through the rectangular groove on the front side of the mounting box. When the color plate moves upward, the bottom color plate is exposed through the rectangular groove. The two color plates are different in color. The user can judge whether the liquid storage tube is installed by observing the color plate exposed on the mounting box, thereby preventing the user from making a misjudgment that affects subsequent use.

[0019] 2. The present invention realizes rapid installation of the liquid storage tube by rotating the mounting block in the mounting ring when the liquid storage tube is installed. When the liquid storage tube is rotated ninety degrees, the movable rod is pushed to the top. At this time, the locking block is supported by the first spring and inserted into the limiting groove on the mounting block, thereby realizing rapid installation of the liquid storage tube. During this process, when the user rotates the liquid storage tube, the hand will feel a slight jam or change in resistance, and a certain sound will be produced at the moment of insertion of the locking block. Through these feedbacks, the user can clearly know that the liquid storage tube has been successfully locked. When disassembly is required, the pressing rod on the top is pressed to squeeze the locking block. At this time, the locking block disengages from the limiting groove, and the liquid storage tube can be quickly removed by rotating the liquid storage tube, thereby realizing rapid installation and disassembly of the liquid storage tube.

[0020] 3. In the present invention, the third spring presses against the locking member, and the locking member fixes the gear, thereby fixing the rotating rod and the sealing plate. When the left end of the liquid storage tube is not connected to a needle or an infusion tube, the sealing plate blocks the liquid outlet on the connecting member, preventing the medicine inside the liquid storage tube from spilling out and causing waste when not in use.

[0021] 4. In the present invention, when the mounting disc is attached to the connecting member, the trigger rod will insert into the connection box. At this time, the trigger rod presses against the rack and compresses the fourth spring. When the rack moves, it will first press against the locking member and move it upward. At this time, the locking member disengages from the gear, and the rack continues to move and meshes with the gear, thereby driving the gear to rotate. When the gear rotates, it drives the rotating rod and the sealing gasket to rotate. At this time, the sealing gasket disengages from the liquid outlet on the connecting member, and the medicine inside can flow out normally for use.

[0022] 5. In the present invention, by pressing the mounting disc on the connecting member, at this time, the two moving members inside the connecting member latch onto the two fixing slots on the mounting disc, achieving the rapid fixation of the mounting disc and the infusion tube. When it is necessary to disassemble the mounting disc, press the pressing block on the connecting member. The pressing block compresses the fifth spring and pushes the connecting rod and the two moving members to move. The two moving members disengage from the two fixing slots on the mounting disc, thereby achieving the rapid disassembly of the mounting disc. After the mounting disc is disassembled, the trigger rod disengages from the connection box. At this time, the fourth spring presses against the rack to reset. When the rack resets, it drives the gear, the rotating rod, and the sealing plate to block the liquid outlet on the connecting member again. After the rack resets, the third spring rebounds to make the locking member lock the gear, preventing the liquid in the liquid storage tube from spilling out when not in use.

Specific implementation mode

[0033] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the specification drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to the attached Figure 1 - attached Figure 4 , the embodiment of the present invention provides an insulin pump drug reservoir with an installation feedback function, including an insulin pump body 1. A mounting box 2 is fixedly connected to the left side of the insulin pump body 1. An installation ring 7 is fixedly connected to the front side of the mounting box 2. Two second sliding rods 13 are fixedly connected between the top and bottom of the inner wall of the mounting box 2. Two color plates 9 are slidably connected between the two second sliding rods 13. A second spring 14 is fixedly connected between the top of the top color plate 9 and the mounting box 2. A moving rod 33 is fixedly connected between the two color plates 9. The left side of the moving rod 33 penetrates and extends into the installation ring 7. A liquid storage tube 32 is arranged inside the insulin pump body 1. Two installation blocks 16 are fixedly connected to the surface of the liquid storage tube 32. Limiting grooves 17 are formed on the surfaces of the two installation blocks 16. A piston 15 is slidably connected to the inner diameter of the liquid storage tube 32. A connecting piece 3 is fixedly connected to the left end of the liquid storage tube 32. A fixing component is arranged inside the mounting box 2, and the fixing component is used to fix the liquid storage tube 32.

[0035] Specifically, the user inserts the liquid storage tube 32 into the insulin pump body 1, and then rotates the liquid storage tube 32. The liquid storage tube 32 drives the mounting block 16 to rotate in the mounting ring 7. During the rotation of the mounting block 16, the moving rod 33 is supported and moved upward. The moving rod 33 drives the two color plates 9 to move along the second slide bar 13 in the mounting box 2. When not installed, the top color plate 9 is supported by the second spring 14 and exposed through the rectangular groove on the front side of the mounting box 2. When installing, the color plate 9 moves upward and the bottom color plate 9 is exposed through the rectangular groove. The user observes the color of the color plate 9 exposed on the mounting box 2 to determine whether the liquid storage tube 32 is installed.

[0036] See attached Figure 2 and attached Figure 4 The fixing component includes a first slide bar 12, which is fixedly connected to the installation box 2. A locking block 10 is slidably connected to the surface of the first slide bar 12. The left side of the locking block 10 penetrates and extends to the inner diameter of the installation ring 7. A first spring 11 is fixedly connected between the rear side of the locking block 10 and the installation box 2. A pressing rod 8 is provided on the top of the locking block 10, and the pressing rod 8 is slidably connected to the installation box 2.

[0037] Specifically, when the user inserts the liquid storage tube 32 into the mounting ring 7 and rotates it, the mounting block 16 rotates accordingly. When the liquid storage tube 32 rotates ninety degrees, the mounting block 16 triggers the moving rod 33 to move it upward. At the same time, because the first spring 11 is connected between the rear side of the locking block 10 and the mounting box 2, after the liquid storage tube 32 is rotated into place, the elastic force of the first spring 11 pushes the locking block 10 so that its left side is inserted into the limiting groove 17 on the surface of the mounting block 16, thereby fixing the liquid storage tube 32 in the mounting ring 7 and completing the quick installation; if the liquid storage tube 32 needs to be removed, the pressing rod 8 that is slidably connected to the mounting box 2 at the top of the locking block 10 is pressed, and the pressing rod 8 drives the locking block 10 to squeeze the elastic force of the first spring 11 to move, so that the locking block 10 is disengaged from the limiting groove 17. At this time, the liquid storage tube 32 can be quickly removed by rotating it, thereby realizing convenient fixing and disassembly of the liquid storage tube 32 at the mounting box 2 on the insulin pump body 1.

[0038] See attached Figure 5 -Attached Figure 7 A connecting box 19 is fixedly connected to the inner wall of the connecting piece 3, a gear 21 is rotatably connected to the rear side of the inner wall of the connecting box 19, a rotating rod 20 is fixedly connected to the front end of the gear 21, a sealing plate 18 is fixedly connected to the surface of the rotating rod 20, and the sealing plate 18 is tightly fitted to the connecting piece 3.

[0039] Specifically, when the needle or the infusion tube 5 is not connected, the sealing plate 18 fits tightly against the connector 3 to block the liquid outlet on the connector 3 to prevent the medicine inside the liquid storage tube 32 from spilling out.

[0040] See attached Figure 6 and attached Figure 7, a locking member 22 is slidably connected to the right side inside the connection box 19. The locking member 22 is meshed with the gear 21. A third spring 23 is fixedly connected between the top of the locking member 22 and the connection box 19. A rack 24 is slidably connected to the bottom of the inner wall of the connection box 19. A fourth spring 25 is fixedly connected between the right side of the rack 24 and the connection box 19. The rack 24 is meshed with the gear 21.

[0041] Specifically, when the user installs the mounting disk 4 onto the connecting member 3, the trigger rod 30 is inserted into the connection box 19, pressing against the rack 24 and squeezing the fourth spring 25. The rack 24 starts to move. First, it presses against the locking member 22 to move upward, causing the locking member 22 to squeeze the third spring 23 and disengage from the engagement with the gear 21. Subsequently, the rack 24 continues to move and meshes with the gear 21, thereby driving the gear 21 to rotate. The gear 21 drives the rotating rod 20 and the sealing plate 18 to rotate, and the sealing plate 18 disengages from the liquid outlet on the connecting member 3, allowing the drug to flow out normally. When the user disassembles the mounting disk 4, the trigger rod 30 disengages from the connection box 19, and the fourth spring 25 rebounds, pressing against the rack 24 to reset. The rack 24 drives the gear 21 to rotate in the reverse direction, causing the rotating rod 20 and the sealing plate 18 to block the liquid outlet on the connecting member 3 again. At the same time, after the rack 24 resets, the third spring 23 rebounds, pushing the locking member 22 to engage with the gear 21 again, locking the gear 21 to prevent the liquid in the liquid storage tube 32 from spilling out when not in use.

[0042] Refer to the appendix Figure 8 , a pressing block 26 is slidably connected to the front side of the connecting member 3. Two connecting rods 28 are rotatably connected to the rear side of the pressing block 26. Two moving members 29 are rotatably connected to the rear sides of the two connecting rods 28. A fifth spring 27 is fixedly connected between the rear side of the pressing block 26 and the connecting member 3.

[0043] Specifically, when the user wants to fix the mounting disk 4 on the connecting member 3, the mounting disk 4 is pressed on the connecting member 3. At this time, the two moving members 29 inside the connecting member 3 latch onto the two fixing grooves 31, achieving the quick fixation of the mounting disk 4. When it is necessary to disassemble the mounting disk 4, press the pressing block 26 on the front side of the connecting member 3. The pressing block 26 moves backward and squeezes the fifth spring 27. At the same time, the two connecting rods 28 and the moving members 29 rotatably connected to the rear side of the pressing block 26 move under the drive of the connecting rods 28, causing the two moving members 29 to disengage from the two fixing grooves 31 on the mounting disk 4, thereby achieving the quick disassembly of the mounting disk 4.

[0044] Refer to the appendix Figure 9 , a mounting disk 4 is arranged on the left side of the connecting member 3. A trigger rod 30 is fixedly connected to the right side of the mounting disk 4. Two fixing grooves 31 are formed on the right side of the mounting disk 4.

[0045] Specifically, when the trigger rod 30 is installed on the mounting disc 4 and the connecting member 3, it is inserted into the connection box 19 to press the rack 24, thereby controlling the rotation of the sealing plate 18 to open or close the liquid outlet. Two fixing grooves 31 are provided on the right side of the mounting disc 4 and cooperate with the moving member 29 in the connecting member 3 to achieve the quick fixation of the mounting disc 4 and the connecting member 3, ensuring the stability of the connection, making the insulin delivery process stable, and at the same time facilitating installation and disassembly, improving the convenience of use.

[0046] Refer to the appendix Figure 1 and the appendix Figure 2 At the left end of the mounting disc 4, an infusion tube 5 is fixedly connected, and at the bottom end of the infusion tube 5, a connector 6 is fixedly connected.

[0047] Specifically, the infusion tube 5 is used to deliver insulin in the liquid storage tube 32 to the subcutaneous indwelling needle on the patient. The subcutaneous indwelling needle is a flexible tube needle, which consists of a needle core and an outer cannula. When in use, medical staff will first insert the outer cannula with the needle core into the patient's subcutaneous blood vessel, and then pull out the needle core, leaving only the soft outer cannula under the patient's skin for convenient long-term infusion. The connector 6 fixedly connected to the bottom end of the infusion tube 5 is used to connect the subcutaneous indwelling needle. Through the tight connection between the connector 6 and the subcutaneous indwelling needle, it is ensured that insulin can be safely and accurately delivered from the liquid storage tube 32 through the infusion tube 5 to the patient's body, meeting the patient's treatment needs for insulin.

[0048] Refer to the appendix Figure 3 and the appendix Figure 4 In the inner diameter of the mounting ring 7, a chute is provided, and on the left side of the mounting box 2, a rectangular groove is provided, and the rectangular groove is located on the left side of the color plate 9.

[0049] Specifically, the chute provided in the inner diameter of the mounting ring 7 provides guiding and limiting functions for the rotation of the mounting block 16 within the mounting ring 7, enabling the mounting block 16 to rotate stably within the mounting ring 7. The user can observe the color change of the color plate 9 through the rectangular groove on the mounting box 2, thereby intuitively judging whether the liquid storage tube 32 is installed. The setting of the rectangular groove cooperates with the color plate 9 to achieve the installation feedback function, facilitating the user to timely understand the installation status.

[0050] Refer to the appendix Figure 4 On the top of the locking block 10, a triangular groove is provided, and the left side of the locking block 10 is the same size as the limiting groove 17.

[0051] Specifically, the triangular groove formed at the top of the locking block 10 is used when the user presses down the pressing rod 8. The pressing rod 8 squeezes the locking block 10, thereby driving the locking block 10 to move. The left side of the locking block 10 has the same size as the limiting groove 17. When the locking block 10 moves leftward under the action of the first spring 11, it can be inserted into the limiting groove 17 to lock the mounting block 16 and the liquid storage tube 32, ensuring that the liquid storage tube 32 will not accidentally loosen during the use of the insulin pump. At the moment when the locking block 10 is inserted into the limiting groove 17, when the user rotates the liquid storage tube 32, the hand will feel a slight jamming or resistance change, and there will be a certain sound when the locking block 10 is inserted. Through these feedbacks, the user can clearly know that the liquid storage tube 32 has been successfully locked and installed.

[0052] Refer to the appendix Figure 8 and the appendix Figure 9 , the right end of the trigger rod 30 penetrates and extends into the interior of the connection box 19, and the trigger rod 30 is slidably connected to the connection box 19.

[0053] Specifically, this enables the installation disk 4 to be inserted into the interior of the connection box 19 through the trigger rod 30 during installation, so as to drive the rack 24 to rotate the gear 21 and control the rotation of the sealing plate 18 to open or close the liquid outlet, realizing the association between the installation of the installation disk 4 and the liquid outlet control of the liquid storage tube 32, and enabling the insulin pump to automatically adjust the liquid outlet state according to the installation state of the installation disk 4 during use.

[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirits of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
