Description

Technical Field

[0001] This utility model relates to the field of eye drop filling technology, specifically to an aseptic eye drop filling device. Background Technology

[0002] As a special type of medicine that comes into direct contact with the eyes, the quality and safety of eye drops are of paramount importance. In the production process of eye drops, the filling stage is one of the key steps to ensure product quality, and aseptic filling is an indispensable requirement for guaranteeing the quality of eye drops.

[0003] Currently, existing eye drop filling equipment on the market has many shortcomings, making it difficult to meet increasingly stringent production standards and quality requirements. Firstly, it lacks effectiveness in maintaining a sterile environment. Many traditional filling devices lack effective measures to prevent external microorganisms from entering the filling area. Microorganisms in the outside air can easily contaminate the eye drops during filling, leading to excessive microbial levels and affecting the product's safety and efficacy. Even if some devices incorporate simple purification measures, they often fail to create a stable sterile airflow environment, making it difficult to ensure the eye drops remain sterile throughout the filling process. Secondly, the sterilization methods are inadequate. Some devices use a single sterilization method, failing to achieve comprehensive, thorough sterilization and failing to completely eliminate various microorganisms that may be present during filling, thus affecting the sterility of the eye drops. Regarding air circulation, traditional filling devices typically lack a proper air circulation system, directly venting exhaust air to the outside. This not only wastes energy but also potentially pollutes the external environment, increasing reliance on clean external air and raising production costs. Utility Model Content

The material and performance requirements of the solenoid valve 2 are the same as those of the solenoid valve 28.

[0062] A blower hood 25 and a return air hood 21 are respectively installed on the filling box 19 on both sides of the inlet 5 and the outlet 14.

[0063] Both ends of the support box 12 are equipped with high-efficiency filters 9. The interior of the high-efficiency filter 9 is provided with a synthetic fiber layer 29, a glass fiber layer 30 and an activated carbon layer 32 in sequence, and an electret 31 is uniformly arranged inside the high-efficiency filter 9 between the glass fiber layer 30 and the activated carbon layer 32.

[0064] A circulation pump 23 is installed inside the support box 12 on one side of the high-efficiency filter 9. The input end of the circulation pump 23 is connected to the output end of the high-efficiency filter 9, and the output end of the circulation pump 23 is connected to the blower hood 25 through the air outlet pipe 24. The input end of the return air hood 21 is connected to the input end of the high-efficiency filter 9 through the return air pipe 22.

[0065] The blowing hood 25 and the return air hood 21 are respectively installed on both sides of the filling box 19. The blowing hood 25 is connected to the output end of the circulating pump body 23 through the air outlet pipe 24, and is used to blow purified air into the outside of the feed inlet 5 and the discharge outlet 14. The return air hood 21 is connected to the input end of the high-efficiency filter 9 through the return air pipe 22, and is used to draw in the air blown into the outside of the feed inlet 5 and the discharge outlet 14 and purify it.

[0066] The support housing 12 is located below the filling housing 19 and contains a high-efficiency filter 9. The two ends of the high-efficiency filter 9 are respectively positioned inside the support housing 12 to ensure that the air is adequately filtered during circulation.

[0067] The HEPA filter 9 has a synthetic fiber layer 29, a glass fiber layer 30, and an activated carbon layer 32 arranged sequentially inside.

The input end of the circulating pump body 23 is connected to the output end of the HEPA filter 9, and the output end is connected to the blower hood 25 through the air outlet duct 24. The function of the circulating pump body 23 is to deliver the air purified by the HEPA filter 9 to the blower hood 25, thereby realizing the air circulation between the inlet 5 and the outlet 14. This forms a recirculating sterile air barrier structure, creating a stable isolated environment inside the filling box 19 and significantly reducing the possibility of microbial growth.

[0070] The inlet of the return air hood 21 is connected to the inlet of the high-efficiency filter 9 via the return air duct 22, ensuring that air inside the filling chamber 19 can be drawn in and filtered again. This reduces energy consumption and dependence on external clean air, resulting in significant environmental and economic benefits.

[0071] When this application embodiment is used,

[0072] Bottle loading: The bottles 4 to be filled are placed in the positioning slots 27 inside the feeding platform 6. The positioning slots 27 ensure that the bottles 4 remain stable during the conveying process. The drive motor 13 is started, and the transmission device drives the conveyor production line 7 to operate, so that the positioning slots 27 on the feeding platform 6 containing the bottles 4 move along the predetermined path towards the filling box 19.

[0073] Air circulation and purification: The blower hood 25 and return air hood 21 on the filling box 19 on both sides of the inlet 5 and outlet 14 work together. The circulation pump 23 starts, and the air that has been filtered and purified by the high-efficiency filters 9 at both ends inside the support box 12 is delivered to the blower hood 25 through the air outlet duct 24. The blower hood 25 blows the purified air into the outside of the inlet 5 and outlet 14 to form a sterile airflow environment. At the same time, the return air hood 21 draws in the air from the outside of the inlet 5 and outlet 14 and sends it back to the high-efficiency filter 9 through the return air duct 22 for further filtration and purification. The synthetic fiber layer 29 inside the high-efficiency filter 9 first filters larger particles, the glass fiber layer 30 further filters fine particles, the activated carbon layer 32 adsorbs harmful gases and odors in the air, and the electret 31 enhances the capture effect of fine particles through electrostatic adsorption, ensuring the cleanliness of the circulating air.

[0074] Sterilization of the internal environment of the filling box: Before the entire filling process begins, the ultraviolet sterilization lamps 33 at the four corners of the filling box 19 are turned on. The four ultraviolet sterilization lamps 33 are tilted towards the center of the filling box 19, forming a high-intensity ultraviolet radiation area with all-round and no dead angles, which sterilizes the internal space of the filling box 19, kills any microorganisms that may exist, and ensures a sterile filling environment.

[0075] Bottle position monitoring: When bottle 4 moves to the vicinity of filling box 19 along with feeding platform 6, infrared sensors 37 installed on the inner walls of both sides of filling box 19 monitor the position and status of bottle 4 in real time. When bottle 4 reaches the predetermined filling position, infrared sensor 37 sends a signal.

[0076] Medication delivery and distribution: The storage tank 10 in the middle of the support housing 12 stores the eye drops solution to be filled. The filling pump 11 is started, drawing the solution from the storage tank 10 through the input pipe and delivering it through the inlet pipe 26 to the distribution pipe 35 at the top of the filling housing 19. The distribution pipe 35 evenly distributes the solution into each diversion hose 34, at which time the solenoid valve 28 on the diversion hose 34 is in the closed state.

[0077] Quantitative filling preparation: When the infrared sensor 37 detects that the bottle 4 has reached the correct position, the two cylinders 16 installed side by side on the top of the filling box 19 are activated, and the movable top plate 18 is driven by compressed air to move downward along the sliding grooves 20 on both sides of the inner wall of the filling box 19, so that the quantitative cylinder 1 at the bottom of the movable top plate 18 is lowered to the position aligned with the bottle mouth of the bottle 4.

[0078] Quantitative filling of medicine: After the metering cylinder 1 is aligned with the bottle mouth of the bottle 4 and the internal space is ready, the solenoid valve 28 on the diversion hose 34 opens. At the same time, the electric telescopic rod 17 is activated, moving the piston 36 inside the metering cylinder 1 upward, and the medicine flows into the metering cylinder 1 through the diversion hose 34. When the medicine in the metering cylinder 1 reaches the predetermined filling volume, the solenoid valve 28 closes. The solenoid valve 2 on the filling tube 3 opens. At this time, the electric telescopic rod 17 drives the piston 36 downward, squeezing the medicine in the metering cylinder 1 through the bottom filling tube 3, and the medicine is accurately filled into the bottle 4.

[0079] Bottle Discharge: After filling, the bottle 4 continues to move on the conveyor line 7 along with the feeding platform 6, and leaves the filling box 19 through the discharge port 14, completing the entire aseptic filling process of the eye drops. Subsequent processes such as bottle sealing and labeling can then be carried out. Throughout the entire workflow, all components work together to achieve aseptic and precise filling of the eye drops, while ensuring a clean filling environment and efficient energy utilization.
