Abstract
Description
Technical Field
[0001] This utility model relates to the field of quantitative extraction technology of injectable drugs, and more specifically to a quantitative extraction container for cross-linked sodium hyaluronate injection. Background Technology
[0002] The cross-linked sodium hyaluronate injection quantitative extraction container is a pharmaceutical packaging container used in conjunction with cross-linked sodium hyaluronate injection, and belongs to the category of pharmaceutical packaging materials. Through its special design, it can quantitatively extract the injection during use, avoiding dosage errors that may be caused by manual extraction.
[0003] Existing quantitative extraction containers for injectable drugs use a quantitative structure to control the extraction of a specified dose of injectable drug in a single extraction, avoiding human error during manual extraction, ensuring stable drug concentration, and maintaining therapeutic efficacy.
[0004] However, in practical applications, existing quantitative extraction containers for injections typically use the scale on the outer wall of the syringe in conjunction with manual pressing of the plunger to control the extraction volume. This quantitative extraction method requires multi-angle visual inspection after the injection is drawn to ensure the accuracy of the extraction volume. When the extraction container extracts the injection multiple times, the above extraction method is too cumbersome and prone to deviation, which is not conducive to improving extraction efficiency and accuracy.
[0005] Therefore, this application provides a cross-linked sodium hyaluronate injection quantitative extraction container to meet the needs. Utility Model Content
[0006] In view of this, the present invention provides a quantitative extraction container for cross-linked sodium hyaluronate injection, which aims to solve the above-mentioned technical problems.
[0007] To achieve the above objectives, the present invention adopts the following technical solution: A quantitative extraction container for cross-linked sodium hyaluronate injection includes an extraction container body and further includes: A quantitative component is placed at one end of the extraction container body. The quantitative component includes a quantitative slide rod connected to one end of the extraction container body, a quantitative plate slidably connected to the quantitative slide rod, and a push rod slidably connected to the extraction container body. The push rod is slidably connected to the quantitative slide rod. A fixing component is provided, which is placed on one side of the metering component and is used to fix the metering plate to the metering slide rod. The fixing component includes a fixing plate that slides inside the metering plate. An elastic pad is connected to one side of the fixing plate. A locking tooth is connected to the side of the metering slide rod near the elastic pad. The elastic pad engages with the locking tooth.
[0008] Furthermore, the inner side of the metering plate is connected to a rubber buckle, and the fixing plate has a snap-fit groove on the side near the rubber buckle. The fixing plate is snapped into the metering plate through the rubber buckle and the snap-fit groove.
[0009] The beneficial effect of adopting the above-mentioned further solution is that the rubber buckle and the snap-fit groove are used to fix the fixing plate, which helps to further improve the stability of the fixing plate during use.
[0010] Furthermore, an anti-slip coating is provided on the side of the fixing plate near the metering plate.
[0011] The beneficial effect of adopting the above-mentioned further solution is that it keeps the fixing plate stable inside the metering plate, which is conducive to further strengthening the connection between the fixing plate and the metering plate.
[0012] Furthermore, the quantitative slide bar is provided with graduations.
[0013] The beneficial effects of adopting the above-mentioned further scheme are: it facilitates the adjustment of the position of the quantitative plate according to the scale, which is conducive to the precise control of the extraction amount of the injection.
[0014] Furthermore, a knob is threaded onto the push rod, and a limit plate is provided on the knob. The limit plate is slidably connected to the metering slide rod.
[0015] The beneficial effect of adopting the above-mentioned further solution is that when the limiting plate moves to the top of the extraction container body, the extraction container body restricts the push rod, which facilitates the extraction container body to discharge a certain amount of injection solution.
[0016] Furthermore, a slider is connected to the side of the knob near the limiting plate, and the knob is rotatably connected to the limiting plate through the slider.
[0017] The beneficial effect of adopting the above-mentioned further solution is that it allows the knob to slide along the slide groove via the slider, preventing the limiting plate from jamming the knob.
[0018] Furthermore, the length of the push rod is greater than the length of the extraction container body.
[0019] The beneficial effect of adopting the above-mentioned further solution is that it ensures that the push rod can completely expel the injection agent inside the extraction container body.
[0020] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a quantitative extraction container for cross-linked sodium hyaluronate injection, which has the following beneficial effects: 1. By setting up a quantitative component, the quantitative plate is placed on the quantitative slide rod, making its position higher than the push rod. When the extraction container body needs to extract cross-linked sodium hyaluronate injection, the quantitative plate is first pushed to the specified height to limit the maximum movement distance of the push rod. Then, the push rod is pushed upward. When the push rod contacts the quantitative plate, the push rod will limit the quantitative plate, thereby allowing the extraction container body to extract the specified volume of injection, which helps to improve extraction efficiency and accuracy.
[0021] 2. By setting a fixing component, after the fixing plate is inserted into the inside of the quantitative plate, the fixing plate will push the elastic pad to move towards the clamping teeth. When the clamping teeth are squeezed, the pad will deform and fit tightly with the clamping teeth, so that the fixing plate can firmly fix the quantitative plate on the quantitative slide rod, which improves the stability of the quantitative plate in actual use and further ensures the accuracy of quantitative extraction.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0026] like Figure 1 - Figure 5 As shown, this utility model provides a quantitative extraction container for cross-linked sodium hyaluronate injection, including an extraction container body 1, and further comprising: like Figure 1 - Figure 3 As shown, the quantitative component 2 is placed at one end of the extraction container body 1. The quantitative component 2 includes a quantitative slide bar 21 connected to one end of the extraction container body 1, a quantitative plate 22 slidably connected to the quantitative slide bar 21, and a push rod 23 slidably connected to the extraction container body 1. The push rod 23 is slidably connected to the quantitative slide bar 21. like Figure 1 - Figure 3 As shown, the fixing component 3 is placed on one side of the metering component 2 and is used to fix the metering plate 22 onto the metering slide rod 21. The fixing component 3 includes a fixing plate 31 that slides inside the metering plate 22. An elastic pad 33 is connected to one side of the fixing plate 31. A locking tooth 32 is connected to the side of the metering slide rod 21 near the elastic pad 33. The elastic pad 33 engages with the locking tooth 32. By inserting the push rod 23 into the inside of the extraction container body 1, and since the metering slide rod 21 and the extraction container body 1 are an integral structure, the metering plate 22 is fitted onto the metering slide rod 21, making its position higher than the push rod 23. When the extraction container body 1 needs to extract cross-linked sodium hyaluronate injection, the metering plate 22 is first pushed to a specified height to limit the maximum movement distance of the push rod 23. Then, the push rod 23 is pushed upwards. When the push rod 23 contacts the metering plate 22... The push rod 23 limits the metering plate 22, allowing the extraction container body 1 to extract a specified volume of injection. This physical metering method ensures the consistency of the extraction volume each time and eliminates the need for multi-angle inspection. It solves the problem that controlling the extraction volume by manually pressing the push rod 23 in conjunction with the outer wall scale 26 is too cumbersome and prone to deviation. This method is beneficial to improving extraction efficiency and accuracy. Furthermore, by inserting the fixing plate 31 into the inner side of the metering plate 22, the fixing plate 31 pushes the elastic pad 33 towards the locking teeth 32. Due to the elasticity of the elastic pad 33, it is squeezed and deformed on the locking teeth 32, making the elastic pad 33 and the locking teeth 32 fit tightly together. Thus, the fixing plate 22 is fixed on the metering slide rod 21 by the fixing plate 31, which helps to improve the stability of the metering plate 22 during use and improve the accuracy of quantitative extraction.
[0027] Furthermore, such as Figure 3 As shown, a rubber buckle 34 is connected to the inner side of the metering plate 22, and a snap-fit groove 35 is provided on the side of the fixing plate 31 near the rubber buckle 34. The fixing plate 31 is snapped into the metering plate 22 through the rubber buckle 34 and the snap-fit groove 35. By adhering the rubber buckle 34 to the inside of the metering plate 22, when the elastic pad 33 is snapped into the snap-fit tooth 32, the rubber buckle 34 is snapped into the inner side of the snap-fit groove 35, so that the rubber buckle 34 and the snap-fit groove 35 cooperate to fix the fixing plate 31, which helps to further improve the stability of the fixing plate 31 during use.
[0028] Furthermore, such as Figure 3 As shown, an anti-slip coating 36 is provided on the side of the fixed plate 31 near the metering plate 22. By spraying the anti-slip coating 36 onto the fixed plate 31, the anti-slip coating 36 increases the friction between the fixed plate 31 and the metering plate 22, so that the fixed plate 31 remains stable inside the metering plate 22, which is beneficial to further strengthen the connection between the fixed plate 31 and the metering plate 22.
[0029] Furthermore, such as Figure 3 As shown, the quantitative slide bar 21 has a scale 26. By setting the scale 26 on the quantitative slide bar 21, the quantitative plate 22 can be adjusted according to the scale 26, which is beneficial for accurately controlling the extraction amount of the injection.
[0030] Furthermore, such as Figure 4 As shown, a knob 24 is threadedly connected to the push rod 23. A limiting plate 25 is provided on the knob 24. The limiting plate 25 is slidably connected to the quantitative slide rod 21. By rotating the knob 24, the knob 24 drives the limiting plate 25 to move along the thread on the push rod 23, so that the limiting plate 25 moves to the designated position. Then, the push rod 23 is pushed down, and the limiting plate 25 moves together. When the limiting plate 25 moves to the top of the extraction container body 1, the extraction container body 1 restricts the push rod 23, so that the extraction container body 1 can discharge a quantitative amount of injection solution.
[0031] Furthermore, such as Figure 5 As shown, a slider 27 is connected to the side of the knob 24 near the limiting plate 25. The knob 24 is rotatably connected to the limiting plate 25 through the slider 27. By opening a groove on the limiting plate 25 that matches the slider 27, when the slider 27 is installed inside the groove, the knob 24 slides along the groove through the slider 27, preventing the limiting plate 25 from jamming the knob 24.
[0032] Furthermore, such as Figure 1 As shown, the length of the push rod 23 is greater than the length of the extraction container body 1. By making the length of the push rod 23 greater than the length of the extraction container body 1, and by reserving the movement space for the knob 24 and the limiting plate 25, it is ensured that the push rod 23 can completely discharge the injection agent inside the extraction container body 1.
[0033] like Figure 1 - Figure 5 As shown: By installing the push rod 23 inside the extraction container body 1, and fitting the metering plate 22 onto the metering slide rod 21, and installing the needle on the extraction container body 1, the metering plate 22 is pushed to align with the designated scale 26 on the metering slide rod 21. Then, the fixing plate 31 is pushed, causing the elastic pad 33 to move towards the locking teeth 32. The elastic pad 33 is pressed against and deformed by the locking teeth 32, resulting in a tight fit between the elastic pad 33 and the locking teeth 32. Thus, the metering plate 22 is fixed to the metering slide rod 21 by the fixing plate 31. At this time, the rubber buckle 34 engages with the inner side of the locking groove 35, thereby fixing the fixing plate 31 by the cooperation of the rubber buckle 34 and the locking groove 35. The anti-slip coating 36 increases the friction between the fixing plate 31 and the metering plate 22, keeping the fixing plate 31 stable inside the metering plate 22. Afterwards, the extraction container body is... 1. Inserted inside the packaging bag of cross-linked sodium hyaluronate injection, push the push rod 23 upwards. Push rod 23 extracts the injection into the interior of the extraction container body 1. When push rod 23 contacts the metering plate 22, push rod 23 limits the metering plate 22, so that the extraction container body 1 extracts the specified volume of injection, which helps to improve extraction efficiency and accuracy. When it is necessary to inject the injection into a specified position, first rotate knob 24. Knob 24 pushes the limiting plate 25 on push rod 23 to the specified position. The position of the limiting plate 25 is compared with the scale 26 to determine the volume. Finally, push rod 23 is pushed. Push rod 23 drives the limiting plate 25 to move along the metering slide 21. When the limiting plate 25 moves to the top of the extraction container body 1, the extraction container body 1 limits push rod 23, which facilitates the extraction container body 1 to discharge a specified amount of injection solution.
