Technical Field

[0001] This utility model relates to a disinfection and sterilization device, and more particularly to an ethylene oxide sterilization device for eye drop bottles and caps during eye drop production. Background Technology

[0002] Eye drops come into direct contact with the mucous membranes of the eye, so the sterility of the medication is extremely important. During the production of eye drops, the medication, the bottle, and the cap all need to be sterilized.

[0003] The eye drop bottle body and cap are mainly made of plastic, and some caps have rubber gaskets. Sterilization needs to take into account both material resistance and sealing. Therefore, the eye drop bottle body and cap are often sterilized by ethylene oxide sterilization. The equipment used is an ethylene oxide sterilization cabinet, which has the advantages of strong penetration, sterilization without dead corners, low temperature sterilization, and protection of heat-sensitive materials.

[0004] Larger ethylene oxide sterilizers have an internal capacity exceeding 10 cubic meters. Their doors are quite heavy and are typically equipped with electric or pneumatic drives. However, due to the weight of the discharge door, opening and closing it is difficult, and the door's support structure is prone to deformation after long-term use, affecting the smoothness and efficiency of opening and closing.

[0030] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0031] This embodiment describes a sterilization device for eye drop production, including a sterilization chamber, a vacuum system, a heating and circulation system, a humidification system, an ethylene oxide vaporization system, a residue removal system, and a control system. The sterilization chamber includes a cabinet 1 and a cabinet door 2. This invention improves the support and guiding structure between the cabinet door 2 and the cabinet 1 of this type of ethylene oxide sterilization cabinet; therefore, other systems are not described in detail.

[0032] like Figure 1 As shown, the support and guide structure between the cabinet door 2 and the cabinet body 1 includes the cabinet body 1, the cabinet door 2, the upper support assembly 3, the lower support assembly 5, and the transverse drive mechanism 4.

[0033] like Figure 1 As shown, the cabinet 1 has an internal cavity for accommodating items to be sterilized and for introducing sterilizing agent (vaporized ethylene oxide). The cabinet 1 is rectangular in shape, with an inlet door at the front and an outlet door at the rear. In this embodiment, the inlet door and outlet door are collectively referred to as cabinet door 2. The cabinet 1 rests on the floor 100 of the clean area of ​​the workshop via a base 7 at its bottom.

[0034] Inflatable sealing rings 11 are provided on the front and rear inlet / outlet side walls of cabinet 1 to form a sealing structure between cabinet 1 and cabinet door 2.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, a hanging arm 2-1 is fixedly installed on the top of the cabinet door 2, and a hanging wheel 2-4 is installed on the hanging arm 2-1; the upper support assembly 3 includes a crossbeam 3-1 fixed on the cabinet body 1 and an upper guide rail 3-2 fixed on the crossbeam 3-1. The hanging arm 2-1 suspends the cabinet door 2 on the crossbeam 3-1, and the hanging wheel 2-4 cooperates with the upper guide rail 3-2.

[0036] A portion of the crossbeam 3-1 is fixed to the top of the cabinet 1 via a fixing bracket 16, while the other portion is suspended. A horizontally extending connecting plate 3-3 is fixedly installed at the suspended end of the crossbeam 3-1. The upper end of the diagonal support 3-4 is fixedly connected to the end of the crossbeam 3-1 via the connecting plate 3-3, and the lower end of the diagonal support 3-4 is fixedly connected to the base 7 at the bottom of the cabinet 1. The diagonal support 3-4 provides support for the suspended end of the crossbeam 3-1, preventing it from bending or deforming. A horizontal gap is formed between the diagonal support 3-4 and the crossbeam 3-1 to allow the cabinet door 2 to open smoothly. The use of the diagonal support 3-4 reduces the space occupied in the workshop, allowing for convenient passage of personnel, equipment, and materials in the corresponding location.

[0037] like Figure 1 and Figure 3As shown, the lower support assembly 5 includes a support frame fixed to the lower part of the distal end 201 of the cabinet door 2 and casters 5-2 mounted on the support frame; the casters 5-2 can directly contact the ground 100; or a corresponding track can be provided.

A recessed portion 6-1 is provided at one end of the groove 6 near the cabinet body 1, the recessed portion 6-1 forming a smooth transition slope for the lower guide rail 8. When the cabinet door 2 is nearly closed, the casters 5-2 do not contact the lower guide rail 8, avoiding any impact from the lower guide rail 8 on the cabinet door 2.

[0038] like Figure 3 The support frame of the lower support assembly 5 shown includes an L-shaped support plate 5-1 and a rib plate 5-3 fixed on the support plate 5-1.

[0039] The horizontal movement drive mechanism 4 is fixed to the top of the cabinet 1, and the movable end of the horizontal movement drive mechanism 4 is fixedly connected to the upper end of the far end 201 of the cabinet door 2 through an L-shaped push plate 2-3. The cabinet door 2 is opened and closed by driving the horizontal movement drive mechanism 4 to slide horizontally along the upper guide rail 3-2. The horizontal movement drive mechanism 4 adopts a cylinder or an electric push rod.

[0040] Multiple first baffles 9 are fixedly installed on one side of the cabinet body 1 to engage with the near end of the cabinet door 2. A second baffle 10 is installed on the base 7 at the bottom of the cabinet body 1 to restrict the lower end of the cabinet door 2. Multiple limiting plates 2-2 are fixedly installed at the far end of the cabinet door 2. The side wall of the cabinet body 1 is provided with a slot 1-1 that engages with the limiting plate 2-2. When the cabinet door 2 is closed, the end of the limiting plate 2-2 is inserted into the slot 1-1. The left and right sides of the slot 1-1 are chamfered to facilitate the insertion of the limiting plate 2-2. The first baffles 9, the second baffles 10, and the limiting plates 2-2 are used to prevent the cabinet door 2 from moving outward, so that a sealing structure is formed between the cabinet body 1 and the cabinet door 2 after the inflatable sealing ring 11 is inflated.

[0041] like Figure 4 As shown, the hanging wheel 2-4 is positioned close to the center surface of the cabinet door 2, ensuring the cabinet door 2 is balanced front to back and preventing excessive tilting that could affect its normal operation. The lifting arm 2-1 is in an inverted J-shape, with its end extending downwards to form a limiting part. This limiting part cooperates with the upper guide rail 3-2 or the crossbeam 3-1 to prevent the hanging wheel 2-4 from disengaging from the upper guide rail 3-2.

[0042] like Figure 1 , Figure 5As shown, a locking cylinder 12 is provided on the top of the cabinet 1, and a pin 13 is fixedly provided at the end of the locking cylinder 12.
