Description

Technical Field

[0001] This utility model relates to the technical field of pharmaceutical powder dispensing and metering devices, specifically a metering device for dispensing injectable meropenem sodium powder. Background Technology

[0002] Meropenem sodium is a broad-spectrum penicillin antibiotic that exerts its bactericidal effect by inhibiting the synthesis of bacterial cell walls. It has antibacterial activity against a variety of Gram-positive and Gram-negative bacteria. Its effect on Gram-positive bacteria is slightly less than that of penicillin G, but its effect on Enterococcus faecalis is better than that of ampicillin and other antibiotics.

[0003] In the production process of meropenem sodium, the dispensing and metering of the drug powder is a crucial step. Its metering accuracy directly affects the quality and efficacy of the drug. From the perspective of drug quality, as an antibiotic, the accuracy of the dosage of meropenem sodium is the core of ensuring the stability of the drug. If there is a deviation in the dispensing and metering, the dosage may be too high, which may cause the drug powder to undergo chemical changes during storage due to excessive component concentration, such as accelerated degradation and the generation of harmful substances. The dosage may be too low, which may cause the drug to lose its due antibacterial activity within the shelf life due to insufficient effective ingredients.

[0004] Some equipment uses manual gates or simple mechanical sealing devices, which makes it difficult to achieve a perfect fit between the seal and the feed hopper diameter. Gaps are likely to appear during the sealing process, causing powder leakage. This not only leads to waste of raw materials and increased production costs, but also may cause the powder to be exposed to the air and contaminated by external impurities such as dust and microorganisms, which will damage the purity of the powder and make it unable to meet the stringent hygiene standards for injectable drugs.

[0005] Therefore, a metering device for dispensing injectable meropenem sodium powder is proposed to address the above problems. Utility Model Content

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.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Please see Figures 1-6 This utility model provides a technical solution:

[0032] A metering device for dispensing injectable meropenem sodium powder includes a dispensing box 1, a feeding hopper 2 installed on the top of the dispensing box 1, a conical discharge hopper 3 fixedly connected to the bottom of the dispensing box 1, a support plate 4 fixedly connected to the bottom of the dispensing box 1, a movable base 5 fixedly connected to the bottom of the support plate 4, a metering device 6 installed on the top of the movable base 5, and a sealing mechanism 7 installed on the top of the feeding hopper 2.

[0033] The sealing mechanism 7 includes a stabilizing plate 71, a connecting block 72 slidably connected to the outside of the stabilizing plate 71, a lifting groove 73 opened inside the stabilizing plate 71, a sliding rod 74 fixedly connected to the outside of the connecting block 72, a sealing plate 75 fixedly connected to the outside of the sliding rod 74, and a sealing plate 76 fixedly connected to the bottom of the sealing plate 75.

[0034] It should be noted that: an electric telescopic rod 77 is fixedly connected to the top outer side of the stabilizing plate 71, a push rod 78 is fixedly connected to the output end of the electric telescopic rod 77, and the bottom of the push rod 78 is fixedly connected to the top of the connecting block 72. A scale plate 21 is provided on the outer side of the feed hopper 2, a controller 11 is fixedly connected to the outer side of the dispensing box 1, and the feed hopper 2, the dispensing box 1 and the conical discharge hopper 3 are in a connected state. The metering device 6 is located directly below the conical discharge hopper 3. The stabilizing plate 71 is fixedly connected to the top outer side of the feed hopper 2. The sliding rod 74 is slidably connected to the inside of the lifting groove 73. The sealing plate 75 and the sealing plate 76 are movably connected to the top of the feed hopper 2, and the sealing plate 76 is adapted to the diameter of the feed hopper 2.

[0035] Furthermore, the packaging box 1 serves as the main frame, realizing the automated process of feeding and metering the medicine powder. The overall structure, from top to bottom, consists of: the feeding hopper 2 responsible for introducing the medicine powder; the packaging box 1 serving as a transfer and processing space; the conical discharge hopper 3 guiding the medicine powder to fall accurately; and the metering device 6 at the bottom quantitatively measuring the falling medicine powder. At the same time, the equipment is equipped with a movable base 5, which allows for flexible adjustment of the position according to operational needs. The support plate 4 enhances the connection stability between the packaging box 1 and the movable base 5.

[0036] Specifically: The stabilizing plate 71 is fixed on the outer side of the top of the feed hopper 2 as the supporting base of the sealing mechanism 7. After the electric telescopic rod 77 is started, it drives the connecting block 72 to slide along the lifting groove 73 of the stabilizing plate 71 through the push rod 78. The connecting block 72 drives the sealing plate 75 and the sealing plate 76 to rise and fall synchronously through the slide rod 74. When rising, the feed hopper 2 opens and the powder enters the packaging box 1. When falling, the sealing plate 76 fits the opening of the feed hopper 2 to achieve sealing.

[0037] As a further implementation of this solution, a stirring mechanism 8 is provided on the outer side of the sealing plate 75. The stirring mechanism 8 includes a motor 81, and a rotating shaft 82 is fixedly connected to the output end of the motor 81. A rotating cover 83 is fixedly connected to the outer side of the rotating shaft 82, and a stirring blade 84 is fixedly connected to the outer side of the rotating cover 83.

[0038] It should be noted that: the motor 81 is fixedly connected to the top of the sealing plate 75, the rotating shaft 82 runs through the inside of the sealing plate 76, and the stirring blades 84 are evenly distributed on the outside of the rotating shaft 82.

[0039] Furthermore: Motor 81 drives the rotating shaft 82 to rotate, which in turn drives the outer rotating cover 83 and stirring blade 84 to rotate. The stirring blade 84 extends into the feed hopper 2 or the dispensing box 1 (adjusted according to the position of the sealing plate 75) to stir the powder, preventing clumping caused by moisture or accumulation, and ensuring smooth feeding and accurate metering (meropenem sodium powder has fine particles and is prone to clumping, so stirring is especially important).

[0040] Work process: Before the powder dispensing and metering work, the equipment can be flexibly moved to the required working position via the movable base 5. When the work starts, the sealing mechanism 7 is in the open state. Specifically, the electric telescopic rod 77 is started by the controller 11. The output end of the electric telescopic rod 77 drives the push rod 78 to move upward. The push rod 78 drives the connecting block 72 to slide on the outside of the stabilizing plate 71. At the same time, the connecting block 72 drives the sliding rod 74 to slide upward in the lifting groove 73. The sliding rod 74 then drives the sealing plate 75 and the sealing plate 76 to move upward, so that the sealing plate 76 is separated from the top of the feed hopper 2, and the feed hopper 2 is in the open state.

[0041] Operators can pour meropenem sodium powder into feed hopper 2. The amount of powder poured in can be visually observed through the scale plate 21 on the outside of feed hopper 2. The powder enters the dispensing box 1 through feed hopper 2. At this time, the stirring mechanism 8 starts to work. The controller 11 controls the motor 81 to start. The output end of the motor 81 drives the rotating shaft 82 to rotate. The rotating shaft 82 drives the rotating cover 83 and the stirring blade 84 to rotate together. Since the stirring blade 84 is evenly distributed on the outside of the rotating shaft 82 and the rotating shaft 82 passes through the inside of the sealing plate 76, the rotating stirring blade 84 can fully stir the powder in the dispensing box 1 and feed hopper 2 to prevent the powder from accumulating and clumping, and ensure that the powder is in a uniform and loose state.

[0042] When metering and dispensing are required, the powder enters the conical discharge hopper 3 from the dispensing box 1 under the action of gravity, and falls through the conical discharge hopper 3 into the metering device 6 located directly below it. The metering device 6 accurately measures the falling powder.

[0043] If feeding needs to be paused or after feeding is completed, the output end of the electric telescopic rod 77 is controlled by the controller 11 to drive the push rod 78 to move downward, which in turn drives the sealing plate 75 and the sealing plate 76 to move downward through the connecting block 72 and the sliding rod 74, so that the sealing plate 76 fits against the top of the feeding hopper 2. Since the sealing plate 76 is compatible with the diameter of the feeding hopper 2, the feeding hopper 2 can be effectively sealed to prevent the powder from falling or external impurities from entering.

[0044] Throughout the process, the feed hopper 2, the dispensing box 1, and the conical discharge hopper 3 remain connected to ensure that the powder can flow smoothly. The controller 11 can uniformly control components such as the electric telescopic rod 77, the motor 81, and the metering device 6 to realize the automated and precise operation of powder dispensing and metering.

[0045] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
