The sodium chloride filling machine is a device used for the automatic filling of sodium chloride injection. The following will introduce it from dimensions such as its working principle, structural composition, main characteristics, and application scenarios:
Mixing of Liquid Medicine
The sodium chloride injection and the solvent are added to the mixing tank of the filling machine in a certain proportion. The mixing tank usually has a stirring device, which can fully mix the solvent and the sodium chloride injection to ensure the uniformity of its components.
Withdrawing of Liquid Medicine
The well - mixed liquid is pumped into the syringe filling system of the filling machine through a pump system. The syringe filling system usually consists of one or more syringe filling heads, and each filling head is responsible for injecting into one syringe.
Filling of Liquid Medicine
The syringe filling head inserts a catheter into the piston hole of the syringe to ensure there is no air inside the syringe. Then, through the movement of the piston, the mixed liquid is injected into the syringe.
Liquid - level Monitoring
During the syringe filling process, sensors and a control system monitor the liquid - level and liquid flow situation of the syringe. Once the liquid - level reaches the preset value or there is an abnormal flow, the system will stop the filling of the syringe to ensure that each syringe is filled correctly.
Sealing and Labeling
After filling, the filling machine usually performs subsequent processes such as sealing and label - attaching. Sealing is usually achieved by heating the soft plastic tube material of the syringe with a heating element, causing it to melt at a certain temperature and seal the sealing part of the syringe.
Medicine - filling Device
It is used to store and transport sodium chloride injection, and usually includes components such as a liquid storage tank and infusion pipelines.
Filling System
It is the core part of the filling machine, responsible for accurately injecting sodium chloride injection into syringes or bottles. It mainly consists of syringe filling heads, pistons, pumps, etc.
Control System
It is used to control the entire working process of the filling machine, including setting filling parameters, monitoring the operating status of the equipment, and handling abnormal situations. It generally consists of a PLC (Programmable Logic Controller), touch - screen, sensors, etc.
Conveying Device
It is used to transport empty syringes or bottles to the filling position of the filling machine and transport the filled products out. Common conveying devices include conveyor belts, turntables, etc.
High - precision Filling
By adopting a precise metering system and advanced filling technology, it can achieve high - precision filling. The error can be controlled within ±1%, ensuring the accurate dosage of sodium chloride injection in each syringe or bottle.
High Degree of Automation
It can realize fully automated operations from material mixing, filling, sealing to labeling, reducing manual intervention, improving production efficiency, and at the same time reducing the risks of contamination and errors caused by manual operations.
Good Stability
The equipment is made of high - quality materials and advanced manufacturing processes, with a solid structure, stable and reliable operation. It can work continuously for a long time, reducing equipment failures and downtime, and improving the continuity and stability of production.
Multifunctionality
It can be used not only for filling sodium chloride injection but also for filling other types of injections, such as glucose injection, normal saline injection, etc., having strong versatility.
Hygiene and Safety
It complies with relevant hygiene standards and requirements. The contact parts of the equipment are made of corrosion - resistant and non - toxic materials, which are easy to clean and disinfect, ensuring the safety and hygienic reliability of the product.
Pharmaceutical Manufacturing Enterprises
It is used for the large - scale production of sodium chloride injection to meet the needs of clinical treatment, medical care, etc. It can improve production efficiency, ensure product quality, and reduce production costs.
Hospital Preparation Rooms
The preparation rooms of some large hospitals can use sodium chloride filling machines to prepare and fill sodium chloride injection by themselves to meet the clinical needs of their own hospitals. At the same time, it can also ensure the freshness and quality of the drugs.
Regular Cleaning
Clean the outer shell of the filling machine with appropriate cleaning agents and soft cloths to avoid dust accumulation. At the same time, be careful not to let water or cleaning agents enter the interior of the equipment. Disassemble and clean components such as the screws, filling heads, and pipelines of the filling machine to remove residual liquid medicine and dirt, preventing blockages and contamination.
Inspecting and Replacing Components
Regularly check the wearing parts of the filling machine, such as seals, pistons, valves, etc. If there is wear, aging, or damage, replace them in a timely manner to ensure the sealing performance and normal operation of the equipment. Check the operating conditions of components such as electrical components, sensors, and conveyor belts. If there are faults or damage, repair or replace them in a timely manner.
Lubrication and Maintenance
Lubricate the moving parts of the filling machine, such as screws, bearings, chains, etc. Apply an appropriate amount of lubricant to the surface of the components to ensure their normal operation and reduce wear.
Calibrating the Metering System
Regularly calibrate the metering system of the filling machine to ensure the accuracy of filling. Standard measuring tools can be used to measure and adjust the filling volume. If there is a deviation, calibration should be carried out in a timely manner.
