Abstract
Description
Technical Field
[0001] This utility model relates to the field of injection pen technology, and more specifically, to a disposable drug cartridge mechanism. Background Technology
[0002] The concept of a pen injector emerged in the late 20th century, named for its pen-like shape. Primarily used for insulin injection, it is also known as an insulin pen or injection pen. This injector combines the injectable solution and the syringe into one, offering advantages such as accurate dosage setting, ease of use, portability, and suitability for home use. It avoids the risk of accidentally breaking the syringe when using a glass injector. Therefore, it was widely welcomed by diabetic patients upon its introduction and gradually became the preferred tool for insulin therapy.
[0003] Furthermore, with increasing attention being paid to protein and peptide drugs, pen injectors are showing increasingly broader application prospects. Currently, pen injectors are widely used clinically, not only for insulin therapy in diabetic patients but also for growth hormone therapy in patients with short stature. Simultaneously, with continuous technological advancements and wider application, pen injectors are also finding widespread use in the cosmetic field.
[0004] Patent document CN115252967B discloses an electronic injection pen and its control method. The control method includes: the electronic injection pen has a function key; when the function key is triggered, the operation state of the function key is acquired; based on the operation state of the function key and the preset function state of the electronic injection pen, the pen is switched to a first function state; or, based on the operation state of the function key and the first function state, the pen is switched to a second function state; and, based on the operation state of the function key, parameters of the current function state are configured. The preset function state of the electronic injection pen is an venting function state, and the current function state of the electronic injection pen is a cartridge replacement function, an injection parameter setting function, and an injection function. The electronic injection pen and its control method proposed in this application both continue the usage habits of mechanical syringes and conveniently realize multiple function settings, ensuring precise injection, convenient and safe use, and providing an extremely user-friendly experience.
[0005] When replacing the cartridge in existing injection pens, there is no locking device in the cartridge, so the cartridge cannot be fixed in the cartridge. The cartridge can easily fall off and be damaged. After replacement, the position of the cartridge is not fixed, which can easily cause deviation from the position of the power unit, resulting in inaccurate dosage.
[0006] Therefore, it is necessary to propose a disposable drug storage mechanism to address the problems existing in the prior art. Utility Model Content

[0038] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments, so that those skilled in the art can implement it based on the description.
[0039] It should be understood that terms such as “having,” “comprising,” and “including” as used herein do not exclude the presence or addition of one or more other elements or combinations thereof.
[0040] like Figures 1-15 As shown, a medicine bottle storage device includes a medicine bottle storage body 5, and an anti-detachment component is provided on the inner wall of the medicine bottle storage body 5.
[0041] Furthermore, the anti-detachment component is an elastic locking block 6 fixedly installed on the lower part of the inner wall of the medicine bottle storage body 5.
[0042] Furthermore, the anti-detachment component is an elastic arm 7 fixedly installed on the upper part of the inner wall of the medicine bottle storage body 5, with the suspended end of the elastic arm 7 tilted towards the center of the medicine bottle storage body 5.
[0043] Furthermore, at least two elastic arms 7 are evenly arranged along the circumference of the medicine bottle storage 5.
[0044] Furthermore, the anti-detachment component is a pressure block 8 that is snapped onto the upper end of the medicine bottle storage body 5. At least two protrusions 9 are evenly arranged on the circumferential surface of the pressure block 8. A slot 10 is opened on the side wall of the medicine bottle storage body 5 at a position corresponding to the protrusions 9, and the protrusions 9 are snapped into the slot 10.
[0045] Furthermore, a sliding groove 11 is formed on the upper inner wall of the medicine bottle storage body 5 at a position corresponding to the slot 10, and the bottom surface of the sliding groove 11 is an inclined surface.
[0046] Furthermore, the medicine bottle storage body 5 is detachably connected to the outer shell 1 via the medicine compartment connector 2. A threaded guide groove 15 is opened on the outer circumference of the upper part of the medicine bottle storage body 5. A slider 16 is fixedly installed on the inner wall of the lower part of the medicine compartment connector 2 at a position corresponding to the guide groove 15. The shape of the slider 16 is adapted to the shape of the guide groove 15.
[0047] Furthermore, a first protrusion 17 is fixedly provided on the outer wall of the medicine bottle storage body 5, and a wedge-shaped groove 19 is fixedly provided on the lower end of the inner wall of the medicine compartment connector 2. A second protrusion 18 is fixedly provided in the wedge-shaped groove 19, and the second protrusion 18 is engaged with the first protrusion 17.
[0048] The working principle of the above technical solution:
[0049] When changing the cartridge of a current injection pen, often only the cartridge is replaced, not the cartridge sleeve. The replaced cartridge moves within the sleeve, making it prone to detachment and damage during replacement. Furthermore, the cartridge may be misaligned with the corresponding power unit, leading to inaccurate dosage settings and injections. Since cartridges are mostly made of glass, they require additional external protection during transport and storage. Using anti-detachment devices to secure the cartridge to the sleeve eliminates the need for additional protective sleeves during transport and storage, and prevents the cartridge from falling off during cartridge replacement.
[0050] The injection pen includes a housing 1, inside which are a power component and a display component. The power component is used to inject the liquid medicine in the cartridge, and the display component can observe the dosage set or injected by the injection pen. The lower end of the housing 1 is connected to a medicine cartridge connector 2, which can be fixedly mounted on the housing 1 or detachably connected to the housing 1. The medicine bottle storage includes a medicine bottle storage body 5, which is detachably connected to the medicine cartridge connector 2. A medicine bottle 4 is installed in the inner cavity of the medicine bottle storage body 5. An anti-detachment component is provided on the upper part of the inner wall of the medicine bottle storage body 5 to fix the medicine bottle 4 inside the medicine bottle storage body 5. The pen cap 3 is sleeved on the outside of the medicine bottle storage body 5 to protect the medicine bottle storage body 5.
[0051] Anti-slip components can be designed with various structures, one of which is as follows: Figures 3-5 The elastic locking block 6 shown is located on the lower inner wall of the medicine bottle storage body 5. Two elastic locking blocks 6 are symmetrically arranged with the axis of the medicine bottle storage body 5 as the center line. The side wall of the elastic locking block 6 near the axis of the medicine bottle storage body 5 is inclined. Along the axis of the medicine bottle storage body 5 from top to bottom, the side wall of the elastic locking block 6 gradually tilts towards the axis of the medicine bottle storage body 5. When the medicine bottle 4 is installed into the medicine bottle storage body 5, the head of the medicine bottle 4 moves downward under the guidance of the inclined surface and squeezes the elastic locking block 6. The head of the medicine bottle 4 passes over the elastic locking block 6, and the neck of the medicine bottle 4 is locked by the elastic locking block 6, so that the medicine bottle 4 cannot be removed.
[0052] Another type of anti-detachment component has the following structure: Figures 6-8 The elastic arm 7 shown is located on the upper part of the inner wall of the medicine bottle storage body 5. At least two elastic arms 7 are evenly distributed along the circumference of the medicine bottle storage body 5. The inner cavity of the medicine bottle storage body 5 can be configured as a conical cavity, larger at the top and smaller at the bottom. The inner diameter of the lower part of the medicine bottle storage body 5 is the same as the diameter of the medicine bottle, while the inner diameter of the upper part is larger than the diameter of the medicine bottle. The elastic arm 7 can be directly fixed to the inner wall of the medicine bottle storage body 5. When installing the medicine bottle, the suspended end of the elastic arm 7 deforms under the pressure of the lower part and side wall of the medicine bottle 4, allowing the medicine bottle to enter the medicine bottle storage body 5. After the upper end of the medicine bottle passes the suspended end of the elastic arm 7, the elastic arm 7 returns to its original shape under its own elasticity, and the lower end of the elastic arm 7 abuts against the upper surface of the medicine bottle 4, thus fixing the medicine bottle 4. After the medicine in the medicine bottle 4 is injected, the medicine bottle storage body 5 is detached from the medicine compartment connector 2, and the medicine bottle is replaced along with the medicine bottle storage body 5.
[0053] The shape of the elastic arm 7 can be set as follows: Figure 7 The inner side of the longitudinal section of the elastic arm 7 shown is a straight line, but it can also be set as follows: Figure 8 The inner side of the longitudinal section of the elastic arm 7 shown is an arc.
[0054] The flexible arm 7 can be made of plastic materials such as PP and ABS.
[0055] Another type of anti-detachment component has the following structure: Figures 9-11 The pressure block 8 shown is attached to the upper end of the medicine bottle storage body 5. At least two protrusions 9 are evenly arranged on the circumferential surface of the pressure block 8. A slot 10 is opened on the side wall of the medicine bottle storage body 5 at a position corresponding to the protrusions 9. The protrusions 9 are engaged in the slot 10. After the medicine bottle 4 is inserted into the medicine bottle storage body 5, the pressure block 8 is pressed into the medicine bottle storage body 5, so that the protrusions 9 are engaged in the slot 10. The pressure block 8 is made of elastic material. When pressed into the medicine bottle storage body 5, the protrusions 9 deform and return to their original shape after entering the slot 10, and are engaged in the slot 10. The pressure block 8 can be made of plastic materials such as PP and ABS.
[0056] To facilitate the pressing of the pressure block 8 into the slot 10 of the medicine bottle storage body 5, a sliding groove 11 is formed on the upper part of the inner wall of the medicine bottle storage body 5 at a position corresponding to the slot 10. The bottom surface of the sliding groove 11 is inclined, and the width of the sliding groove 11 is the same as the width of the protrusion 9. The bottom surface of the sliding groove 11 is closer to the axis of the medicine bottle storage body 5 from top to bottom. The lower end of the sliding groove 11 is connected to the slot 10. When installing the pressure block 8, the protrusion 9 of the pressure block 8 is placed into the sliding groove 11, and the pressure block is pushed down until the protrusion 9 passes the lower end of the sliding groove 11 and enters the slot 10.
[0057] The medicine bottle storage body 5 is detachably connected to the outer shell 1 via the medicine compartment connector 2. A spiral guide groove 15 is formed on the outer circumference of the upper part of the medicine bottle storage body 5. A slider 16 is fixedly installed on the inner wall of the lower part of the medicine compartment connector 2 at a position corresponding to the guide groove 15. The shape of the slider 16 is adapted to the shape of the guide groove 15. A first protrusion 17 is fixedly installed on the outer wall of the medicine bottle storage body 5. A second protrusion 18 is fixedly installed on the inner wall of the medicine compartment connector 2 at a position corresponding to the first protrusion 17. The first protrusion 17 and the second protrusion 18 are engaged. When connecting the medicine bottle storage body 5 and the medicine compartment connector 2, the medicine bottle storage body 5 is rotated, causing the slider 16 to slide in the spiral guide groove 15. The upper end of the medicine bottle storage body 5 gradually enters the medicine compartment connector 2. When the second protrusion 18 is engaged with the first protrusion 17, the connection is in place, which can prevent damage caused by excessive rotation and also prevent the medicine bottle storage body 5 from detaching from the medicine compartment connector 2.
[0058] The vial reservoir body 5 features a threaded guide groove 15 with a specific pitch larger than that of a standard thread. The guide groove 15 can also be shaped like a double-ended thread. This allows for quick replacement of the vial reservoir, and the specific pitch prevents the vial reservoir 5 from being installed with other power components, which could lead to inaccurate injection dosages. Similarly, the cross-sectional shape of the guide groove can be rectangular or trapezoidal, different from standard threads, further ensuring the uniqueness of the connection between the vial reservoir body 5 and the medication cartridge connector, preventing confusion with the injection pen.
[0059] A wedge-shaped groove 19 is provided at the lower end of the inner wall of the medicine container connector 2. The second protrusion 18 is fixedly set in the wedge-shaped groove 19. When the medicine bottle storage body 5 is connected to the medicine container connector 2, the first protrusion 17 enters the inside of the wedge-shaped groove 19 and passes over the second protrusion 18 and is stuck by the second protrusion 18, so that the medicine bottle storage body 5 and the medicine container connector 2 are connected together.
[0060] The beneficial effects of the above technical solution are as follows:
[0061] The medicine bottle storage device described in this utility model has an anti-detachment component installed inside the medicine bottle storage device body, which will prevent the medicine bottle inside the medicine bottle storage device body from falling off and being damaged. The position of the medicine bottle and the medicine bottle storage device body is fixed, and there will be no positional deviation between the replaced medicine bottle and the power component, so the dosage is accurate during injection.
[0062] This utility model also provides a disposable medicine storage mechanism, including the medicine bottle storage device described in the above technical solution, and also includes a medicine storage bottle 4, which is installed in the medicine bottle storage body 5. The anti-detachment component in the medicine bottle storage body 5 is used to fix the medicine storage bottle 4.
[0063] like Figures 14-15 As shown, this utility model also provides a disposable medicine container mechanism, including a medicine storage bottle 4 and a medicine bottle storage body 5. The medicine storage bottle 4 is installed in the medicine bottle storage body 5. A second anti-detachment component is provided between the medicine storage bottle 4 and the medicine bottle storage body 5. The second anti-detachment component is an elastic tail wing 12 that is fixedly installed on the upper surface of the medicine storage bottle 4 and folded outward. A groove 13 is opened on the inner wall of the medicine bottle storage body 5 at a position corresponding to the elastic tail wing 12. The elastic tail wing 12 is snapped into the groove 13.
[0064] Two flexible tail fins 12 are symmetrically arranged with the axis of the medicine bottle 4 as the center line.
[0065] After the medicine bottle 4 is placed into the medicine bottle storage 5, the medicine bottle 4 is pressed down. The elastic tail wing 12 is deformed by the pressure of the inner wall of the medicine bottle storage 5, so that the elastic tail wing can enter the medicine bottle storage 5. When the upper end of the elastic tail wing 12 enters the second groove 13, the elastic tail wing returns to its original shape, and the upper end of the elastic tail wing 12 is stuck in the second groove 13, so that the medicine bottle 4 cannot move.
[0066] The beneficial effects of the above technical solution are as follows:
[0067] The disposable medicine container mechanism described in this utility model uses an anti-detachment component to fix the medicine storage bottle to the medicine bottle storage body, which can prevent the medicine bottle set in the medicine bottle storage body from falling off. This makes the medicine bottle and the medicine bottle storage body a non-removable whole. When changing the medicine container, the medicine storage bottle is replaced as a whole, which will not cause the medicine storage bottle to fall off and be damaged. The position of the medicine storage bottle and the medicine bottle storage is fixed, and there will be no positional deviation between the replaced medicine bottle and the power component, so the dosage is accurate during injection.
