Description

Technical Field

[0001] This utility model relates to an automated entry and exit system for sterilizing contact lenses. Background Technology

[0002] Contact lenses are a common vision correction tool. After being packaged, contact lenses need to be transported, which involves two workshops: a cleanroom and a regular workshop. The final contact lens product needs to be transported from the cleanroom to the regular workshop after packaging.

[0003] In the existing technology, most contact lens sterilization devices in this process only use a single isolation door for isolation. When the isolation door is opened, the general area is directly connected to the cleanroom, lacking a buffer zone for material entry and exit, which causes the cleanroom environment to be contaminated. Furthermore, the existing equipment disinfection and transfer facilities are inadequate, resulting in a waste of manual labor during maintenance.

[0004] Therefore, there is an urgent need for an automated in-and-out changing system for contact lens sterilization that can effectively prevent bacterial invasion and is easy to maintain, so as to improve the effectiveness and efficiency of contact lens sterilization. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an automated entry and exit system for contact lens sterilization. Through multiple isolation devices, the sterilization effect is enhanced. This invention achieves its purpose as follows:

[0006] This utility model proposes an automated entry and exit system for sterilizing contact lenses, including an isolation wall with an isolation cavity inside. A motion track is installed inside the isolation cavity, and a transport trolley is installed on the motion track. A first isolation device penetrating into the isolation cavity is installed on the outer surface of one side of the isolation wall, and a second isolation device penetrating into the isolation cavity is installed on the outer surface of the other side of the isolation wall. The first and second isolation devices are arranged alternately.

[0007] Furthermore, the first isolation device is connected to the conveyor belt, and the second isolation device is connected to the conveyor belt.

[0008] Furthermore, the first isolation device includes two sets of isolation doors, and the second isolation device includes two sets of isolation doors.

[0009] Furthermore, a maintenance isolation door is installed on one side of the isolation wall, and a maintenance exit is opened on one side of the isolation wall, with the maintenance isolation door and the maintenance exit connected.

[0010] Furthermore, it also includes a disinfection device, which is installed on one side of the wall and is used to provide disinfectant.

[0011] Furthermore, a disinfection nozzle is installed on the outer surface of the first isolation device, penetrating into the interior of the first isolation device, and the disinfection device is connected to the disinfection nozzle.

[0012] Furthermore, a disinfection nozzle is installed on the outer surface of the first isolation device, penetrating into the interior of the first isolation device, and the disinfection device is connected to the disinfection nozzle.

[0013] Furthermore, the outer surface of the isolation wall is equipped with a disinfection nozzle that extends into the isolation chamber, and the disinfection device is connected to the disinfection nozzle.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: by setting up staggered first and second isolation devices, multiple isolation barriers are formed, which effectively prevents bacteria from entering the sterile room. Compared with the prior art, which only uses one isolation door for isolation, the isolation effect is greatly improved; the automated transmission of contact lenses is achieved through a moving track and a transport trolley, which reduces the risk of contamination caused by manual operation; the internal isolation device is disinfected by a disinfection device and a disinfection nozzle, which further improves the isolation effect and effectively kills any bacteria that may be present.

These embodiments are only used to explain the present utility model and do not constitute a limitation on the scope of protection of the present utility model.

[0018] Example 1

[0019] An embodiment of this utility model proposes an automated entry and exit system for sterilizing contact lenses, including an isolation wall 5, an isolation cavity inside the isolation wall 5, a motion track 10 installed inside the isolation cavity, a transport trolley 11 installed on the motion track 10, a first isolation device 4 penetrating into the isolation cavity installed on the outer surface of one side of the isolation wall 5, and a second isolation device 8 penetrating into the isolation cavity installed on the outer surface of the other side of the isolation wall 5, with the first isolation device 4 and the second isolation device 8 arranged alternately.

[0020] Specifically, the isolation wall 5 is made of stainless steel, possessing excellent corrosion resistance and strength, effectively isolating the external and internal environments to prevent cross-contamination. The isolation wall 5 is 15 cm thick, 2.5 meters high, and its length is adjustable according to actual needs, typically 5-10 meters. An isolation cavity is created within the isolation wall 5, extending through the entire wall to form a closed passageway. The cavity is 80 cm wide and 1.2 meters high, sufficient to accommodate the passage of the transport trolley 11. The motion track 10, installed at the bottom of the isolation cavity, is made of high-strength aluminum alloy, with a width of 60 cm and guide grooves to ensure stable movement of the transport trolley 11. Protective railings are provided on both sides of the motion track 10 to prevent the transport trolley 11 from deviating from the track. The surface of the motion track 10 undergoes special treatment, exhibiting anti-slip and wear-resistant properties, extending its service life. The transport trolley 11 is made of lightweight, high-strength materials, and its bottom is equipped with a pulley system matching the motion track 10, ensuring smooth operation of the trolley on the track. The transport trolley 11 measures 50 cm in length, 40 cm in width, and 30 cm in height. It features a tray on top for holding contact lens containers. The tray is made of medical-grade stainless steel, with a smooth, sterile surface for easy cleaning and disinfection. The transport trolley 11 is equipped with an electric drive system, using a motor to rotate pulleys for automatic movement. The trolley's speed is adjustable, with a maximum speed of 0.5 m / s, ensuring that the contact lens containers do not shake or tip over during transport.

[0021] Understandably, the first isolation device 4 is installed on the outer surface of one side of the isolation wall 5, extending into the isolation cavity to form a closed passage. The first isolation device 4 measures 70 cm wide, 80 cm high, and 30 cm deep, sufficient to allow the transport trolley 11 to pass through. The first isolation device 4 uses a stainless steel frame structure with internal sealing strips to ensure airtightness when closed. The outer surface of the first isolation device 4 is smooth and flat, facilitating cleaning and disinfection.

[0022] Understandably, the second isolation device 8 is installed on the outer surface of the other side of the isolation wall 5, also penetrating into the isolation cavity to form another closed channel. The structure of the second isolation device 8 is the same as the first isolation device 4, but its installation position is staggered with the first isolation device 4. That is, when the first isolation device 4 is located above the isolation wall 5, the second isolation device 8 is located below the isolation wall 5, or when the first isolation device 4 is located on the left side of the isolation wall 5, the second isolation device 8 is located on the right side of the isolation wall 5. This staggered arrangement effectively prevents outside air from directly entering the isolation cavity, reducing the risk of cross-contamination. The first isolation device 4 is connected to the conveyor belt 3, which is made of food-grade silicone, 50 cm wide, and its length is adjustable according to actual needs, typically 2-3 meters. The conveyor belt 3 is driven by a motor, with an adjustable speed of up to 0.3 m / s. The surface of the conveyor belt 3 has anti-slip textures to ensure that the contact lens containers do not slip during transport. One end of the conveyor belt 3 connects to the entrance of the first isolation device 4, and the other end extends into the operating area, facilitating the placement or removal of contact lens containers by staff. The second isolation device 8 is also connected to the conveyor belt 3, which has the same specifications as the conveyor belt 3 of the first isolation device 4, but is installed opposite to it. One end of the conveyor belt 3 of the second isolation device 8 connects to the outlet of the second isolation device 8, and the other end extends to the sterilization area, facilitating the transport of sterilized contact lens containers to the next process. The first isolation device 4 includes two sets of isolation doors 1, namely an outer isolation door 1 and an inner isolation door 1. The outer isolation door 1 is installed on the side of the first isolation device 4 that contacts the external environment, and the inner isolation door 1 is installed on the side of the first isolation device 4 that contacts the isolation chamber. Both sets of isolation doors 1 are made of stainless steel, with a thickness of 1 cm, and the surface is polished, smooth, and sterile. The edges of the isolation doors 1 are equipped with sealing strips to ensure airtightness when closed. The isolation doors 1 are controlled by an electric mechanism, and the opening and closing time is adjustable, usually set to 3-5 seconds. The opening and closing actions of the outer isolation door 1 and the inner isolation door 1 are interlocked. That is, when the outer isolation door 1 is open, the inner isolation door 1 must be closed, and vice versa, to ensure the airtightness of the isolation chamber. The second isolation device 8 also includes two sets of isolation doors 1, with the same structure as the isolation doors 1 of the first isolation device 4, but in the opposite installation positions. The outer isolation door 1 of the second isolation device 8 is installed on the side of the second isolation device 8 that contacts the sterilization area, and the inner isolation door 1 is installed on the side of the second isolation device 8 that contacts the isolation chamber. The opening and closing of the two sets of isolation doors 1 are also interlocked to ensure the airtightness of the isolation chamber.

[0023] Understandably, a maintenance isolation door 6 is installed on one side of the isolation wall 5, and a maintenance exit 7 is also provided on the same side. The maintenance isolation door 6 is connected to the maintenance exit 7. The maintenance isolation door 6 is made of stainless steel, 1.5 cm thick, and measures 80 cm wide and 180 cm high, large enough to accommodate personnel. The edges of the maintenance isolation door 6 are fitted with sealing strips to ensure airtightness when closed. The maintenance isolation door 6 is equipped with a safety lock, allowing only authorized personnel to open it. The maintenance exit 7 is located on the side of the isolation wall 5, matching the dimensions of the maintenance isolation door 6, facilitating personnel access to the isolation chamber for equipment maintenance and cleaning. The system also includes a disinfection device 2, installed on one side of the wall, for providing disinfectant. The disinfection device 2 includes a disinfectant storage tank, a delivery pump, and a control system. The disinfectant storage tank is made of high-density polyethylene, has a capacity of 20 liters, and stores medical-grade disinfectant. The delivery pump is made of corrosion-resistant material, has a power of 200 watts, and a maximum flow rate of 2 liters / minute, capable of delivering disinfectant from the storage tank to each disinfection nozzle 9. The control system uses a programmable logic controller (PLC) which can control the spraying time and frequency of disinfectant according to a preset program.

[0024] Understandably, the outer surface of the first isolation device 4 is fitted with disinfection nozzles 9 that penetrate into the interior of the first isolation device 4, and the disinfection device 2 is connected to the disinfection nozzles 9. The disinfection nozzles 9 are made of stainless steel, have a diameter of 0.5 cm, and feature an atomizing design to atomize the disinfectant into fine particles, evenly covering the interior space of the first isolation device 4. Six disinfection nozzles 9 are installed on the top and sides of the first isolation device 4, forming a 360-degree spray without blind spots. The disinfection nozzles 9 are connected to the disinfection device 2 via pipes made of medical-grade silicone, with an inner diameter of 0.8 cm, ensuring smooth flow of the disinfectant. The outer surface of the isolation wall 5 is fitted with disinfection nozzles 9 that penetrate into the isolation chamber, and the disinfection device 2 is connected to the disinfection nozzles 9. These disinfection nozzles 9 are installed on the top and sides of the isolation chamber, totaling 10, forming a comprehensive coverage of the interior of the isolation chamber. The specifications of the disinfection nozzles 9 are the same as those of the first isolation device 4, and they are also connected to the disinfection device 2 via pipes. These disinfection nozzles 9 can regularly disinfect the isolation chamber, ensuring that the environment inside the isolation chamber remains sterile at all times.

[0025] The automated entry and exit system operates as follows: First, staff place the container containing contact lenses on the conveyor belt 3 outside the first isolation device 4. The conveyor belt 3 transports the container to the entrance of the first isolation device 4. When the container reaches the entrance, the outer isolation door 1 opens, the container enters the first isolation device 4, and the outer isolation door 1 closes. At this time, the disinfection nozzles 9 begin to operate, disinfecting the container and the interior of the first isolation device 4 for 30 seconds. After disinfection, the inner isolation door 1 opens, and the transport trolley 11 enters the first isolation device 4, loads the container, and returns to the isolation chamber, closing the inner isolation door 1. The transport trolley 11 travels along the track 10 to the position of the second isolation device 8. At this time, the inner isolation door 1 of the second isolation device 8 opens, and the transport trolley 11 delivers the container into the second isolation device 8, closing the inner isolation door 1. The disinfection nozzles 9 inside the second isolation device 8 begin to operate, performing a final disinfection of the container for 30 seconds. After disinfection, the outer isolation door 1 opens, and the container is transported by the conveyor belt 3 to the sterilization area for the next sterilization process.

[0026] Throughout the process, the isolation chamber remains sealed, preventing direct contact between the external environment and the sterilization area, effectively preventing cross-contamination. Simultaneously, the sterilization device 2 ensures the sterility of the contact lens containers during transportation.

[0027] When the system requires maintenance or cleaning, personnel can enter the isolation chamber through maintenance isolation door 6 to inspect and maintain equipment such as the motion track 10 and the transport trolley 11. After maintenance is completed, personnel leave through maintenance exit 7, close maintenance isolation door 6, and the system returns to normal operation.
