Description

Technical Field

[0001] This utility model relates to the field of injection production technology, and in particular to a production device for pediatric compound electrolyte glucose injection. Background Technology

[0002] Pediatric compound electrolyte glucose injection is a commonly used intravenous preparation in pediatrics, mainly used to prevent and correct dehydration and electrolyte imbalance in infants and young children. This injection contains electrolytes such as glucose, sodium chloride, potassium chloride, and sodium lactate, which can regulate fluid balance and is suitable for water and electrolyte loss caused by diarrhea, vomiting, fever, or surgery.

[0003] Traditional production of pediatric compound electrolyte glucose injection solutions often employs a single-pipeline, batch-type reactor structure. Raw materials are added sequentially through the same pipeline, relying on simple timing control to complete processes such as dissolution and pH adjustment. This easily leads to segmented production processes, cumbersome operations, and the need to wait for complete dissolution or reaction after each addition before proceeding to the next stage, resulting in low overall efficiency and long cycles. Utility Model Content

[0004] The technical problem to be solved by this utility model is that the traditional production process of compound electrolyte glucose injection usually adopts a single-pipe batch feeding method, which is cumbersome and restricts production capacity efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a production device for pediatric compound electrolyte glucose injection, including a reaction vessel and a feeding pipe body. A connecting groove is opened on one side of the reaction vessel, and the feeding pipe body is fastened to the connecting groove. Connecting seats are fixedly arranged on both sides of the feeding pipe body. The connecting seats are opened with a plurality of vertically arranged connecting circular grooves, and the connecting circular grooves are connected to the inside of the feeding pipe body. A feeding control plate is snapped into the inside of the connecting circular groove. A plurality of solenoid valves are fixedly arranged on the feeding control plate. A cylindrical sealing cylinder is fixedly arranged at the other end of the solenoid valve, and the sealing cylinder is fastened to the connecting circular groove.

[0006] As a further improvement of this utility model, the feeding pipe body is configured as an L-shaped pipe body, and a support seat for the feeding pipe body is fixedly arranged around the connecting groove, and a sealing plate is provided on the top of the support seat. The sealing plate is fastened to the feeding pipe body by bolts.

[0007] As a further improvement of this utility model, a sealing block is fixedly provided on one side of the bottom interface of the feeding pipe body. The sealing block is set as a rectangular frame and filled with a metal plastic frame. A groove matching the sealing block is opened around the connecting groove.

[0008] As a further improvement of this utility model, a rotating motor is fixedly installed at one end of the bottom side of the feeding pipe body, the output end of which passes through the wall of the feeding pipe body, and two rotating leaf valves are fixedly installed on the outer wall of the output end, and the rotating leaf valves are rectangular plate structures.

[0009] As a further improvement of this utility model, a threaded seat is fixedly provided on the top of the connecting seat, a threaded hole is provided at the top of the threaded seat, and a threaded post is threadedly connected in the threaded hole. A buckle plate that abuts against the feeding control plate is fixedly provided at one end of the threaded post.

[0010] As a further improvement of this utility model, the inner walls of the outer sides of the plurality of connecting grooves are all provided with threads, and the threads extend inward to the center side of the connecting seat.

[0011] The beneficial effects of this invention are as follows: By setting a multi-port feed pipe on one side of the reactor and cooperating with connecting seats on both sides, multiple liquid raw materials can be independently and parallelly fed in. The connecting seats have several vertically arranged connecting grooves. External feed pipelines are connected to the outer side of the connecting grooves, and a feed control board is connected to the inner side. Combined with the internal solenoid valve and sealing cylinder, the order of adding solutions such as glucose, sodium chloride, and potassium chloride can be controlled at different times, significantly improving the continuity and flexibility of the batching process.

[0020] This utility model provides a production device for pediatric compound electrolyte glucose injection, including a reaction vessel 1 and a feeding pipe 2;

[0021] As attached Figure 1-4 As shown, a connecting groove is provided on one side of the reactor 1, and a feed pipe body 2 is fastened to the connecting groove. Connecting seats 3 are fixedly installed on both sides of the feed pipe body 2. The connecting seats 3 have several vertically arranged connecting circular grooves, and the connecting circular grooves are connected to the inside of the feed pipe body 2. Threads 11 are provided on the inner walls of the outer sides of the multiple connecting circular grooves, and the threads 11 extend inward to the center side of the connecting seat 3. The threads 11 are used to connect to the external conveying pipeline. After connecting to the conveying pipeline through the external pump body, the liquid material is conveyed into the conveying pipeline. A feed control plate 4 is snapped into the inner side of the connecting circular groove. A threaded seat 9 is fixedly installed on the top of the connecting seat 3. A threaded hole is provided at the top of the threaded seat 9, and a threaded post is threadedly connected to the threaded hole. A buckle plate is fixedly installed at one end of the threaded post to abut against the feed control plate 4, ensuring a reliable connection between the feed control plate 4 and the connecting seat 3. Multiple solenoid valves 5 are fixedly installed on the feeding control board 4. The opening and closing sequence is controlled by PLC programming to control the closing and opening states during liquid material transmission. A cylindrical sealing cylinder is fixedly installed at the other end of the solenoid valve 5, and the sealing cylinder is tightly fitted with the connecting circular groove to ensure a tight connection at the connection point.

[0022] As attached Figure 1 , 2As shown in Figure 4, the feed pipe 2 is an L-shaped pipe. A support 6 is fixedly installed around the connecting groove to support the feed pipe 2. A sealing plate 7 is installed on the top of the support 6, and the sealing plate 7 is fastened to the feed pipe 2 by bolts on both sides. With the support 6, the connecting pipe on the bottom side of the feed pipe 2 can be placed on the connecting groove on one side of the reactor 1. The sealing plate 7, which is spliced ​​with the support 6, ensures that the support 6 and sealing plate 7 are spliced ​​and placed around the feed pipe 2. After screwing in the bolts, the connection between the reactor 1 and the feed pipe 2 is ensured. A sealing block 8 is fixedly installed on one side of the bottom interface of the feed pipe 2. The sealing block 8 is a rectangular frame filled with a metal plastic frame. The plastic frame is used to ensure the support effect of the sealing block 8. A matching groove is opened around the connecting groove to ensure a tight connection when the feed pipe 2 is filled. A rotating motor is fixedly installed at one end of the bottom side of the feeding pipe body 2. Its output end passes through the wall of the feeding pipe body 2, and two rotating leaf valves 10 are fixedly installed on the outer wall of the output end. The rotating leaf valves 10 are rectangular plate structures. This effectively improves the liquid transmission efficiency, reduces the liquid residence time in the pipeline, and optimizes the efficiency and accuracy of the injection liquid feeding process.

[0023] Working principle: In specific implementation, the feeding control plate 4 is first placed on both sides of the feeding pipe body 2. Then, multiple corresponding sealing cylinders are embedded into the connecting circular groove to ensure a tight seal. The threaded post on the threaded seat 9 is rotated inward to make the buckle plate abut against the feeding control plate 4. The bottom end of the feeding pipe body 2 is placed on the support seat 6, and the feeding pipe body 2 and the reaction vessel 1 are reinforced by the sealing plate 7 and bolts.

[0024] During operation, the reactor 1 is connected to multiple external raw material delivery pipelines via connecting seats 3 located on both sides of the feed pipe 2 for quick connection. Each connecting seat 3 has a corresponding thread 11 on its inner wall of the connecting groove for proper connection. The main raw materials are output via corresponding delivery pumps. During operation, glucose solution, sodium chloride solution, potassium chloride solution, and water for injection are used, with the temperature controlled at 50–60°C. Water for injection is injected into the reactor 1 as the solvent base. Multiple solenoid valves 5 open or close sequentially according to a preset program, allowing the corresponding raw material solutions to be injected into the reactor 1 sequentially for dissolution and homogenization under external pumping and gravity assistance, according to the production process.

[0025] Raw materials are introduced through different interface channels, allowing independent control of the feeding sequence and rate of different components, avoiding premature mixing or reaction between components. The opening and closing actions of solenoid valve 5 are controlled by the system and precisely synchronized to ensure a high degree of consistency in the reaction stage. A rotary motor drives the rotary vane valve 10 located on the bottom side of the feed pipe 2, promoting the flow and distribution of liquid in the connecting pipe section and preventing local stagnation. The entire structure is stably installed through the support 6 and the sealing plate 7. The interlocking structure between the sealing block 8 and the reactor 1 further enhances the interface sealing, ensuring no leakage or contamination of the liquid during transportation. This optimized combination of structures achieves the functional goals of "multi-source independent control, automated precise dosing, and continuous feeding," representing an important improvement in the transformation of traditional batch reaction processes towards continuous and integrated processes.
