Description

Technical Field

[0001] This utility model belongs to the field of pharmaceutical equipment technology, and in particular relates to a sterile isolator. Background Technology

[0002] A sterile isolator is a device used to isolate personnel from products during product processing to prevent cross-contamination and protect either the product or the operator. Chinese patent application CN201821708794.7 discloses a flow equalization membrane support structure and an isolator including this structure. In this design, a light is installed on the top plate of the flow equalization membrane support, and the flow equalization membrane is installed below it. This increases the sterilization risk of the isolator and also increases the daily cleaning requirements and costs. The sterile isolator operates in a high-concentration hydrogen peroxide gas environment during sterilization, while the production stage is a sterile environment. The light source component cannot withstand hydrogen peroxide gas for long periods, leading to dim lighting and the need for replacement after prolonged use. Replacing the light source component inside the isolator is difficult, and offline cleaning after disassembly is inconvenient. Furthermore, the wiring of the light source component needs to pass through the isolator, increasing the manufacturing cost of sealing the wiring outlet.

[0003] Chinese patent application CN205535594U discloses a sealed lighting lampshade structure for an isolator; Chinese patent application CN216924143U discloses an isolator with controllable lighting. In the above solutions, the light source is located on the upper part of the isolator. However, the isolator is not a sterile isolator. The light source is located on the upper part, which makes it inconvenient to replace. The installation method of the light source does not meet the sterile isolation requirements of sterile isolator equipment. When sterile laminar flow protection is required inside the isolator, the lighting effect of the above solutions is poor and it is difficult to provide effective illumination. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a sterile isolator that is easy to clean, easy to replace the lamp source components, and can ensure the internal lighting environment of the sterile isolator.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A sterile isolator includes a chamber wall with a light-transmitting opening on its upper side, located on one side below a flow equalization membrane. A locking assembly is provided on the outside of the chamber wall. A light-transmitting plate is provided on the light-transmitting opening, and a sealing gasket is provided around the opening, positioned between the light-transmitting plate and the chamber wall. The light-transmitting plate and the sealing gasket are connected to the chamber wall via the locking assembly. A cover is provided on the outside of the light-transmitting plate, including a mounting portion that slopes downwards towards the outside of the isolator. A lamp source assembly is mounted on the mounting portion, facilitating cleaning of the lamp source assembly inside and outside the isolator, and making it easy to replace the lamp source assembly. This ensures a safe lighting environment inside the sterile isolator, reducing equipment costs and sterilization risks.

[0007] As a further improvement to the above technical solution:

[0008] The locking assembly includes a screw welded to the chamber wall and a nut that matches the screw. The screw passes through a sealing gasket, a light-transmitting plate, and a washer to connect the nut, which facilitates processing and disassembly.

[0009] The side of the housing has an opening that can be used to pass the wires of the lamp source assembly, facilitating processing and disassembly.

[0010] The outer shell is provided with a decorative cover, the bottom of which is inclined and connected to the chamber wall to ensure the overall aesthetics of the structure and ease of cleaning.

[0011] The upper part of the chamber wall is equipped with a laminar flow component to ensure sterility of the chamber through a laminar flow environment.

[0012] The light-transmitting plate is a PC board, and the sealing gasket is a foamed silicone gasket, which achieves both sealing and light transmission and is not easily damaged.

[0013] The cover is locked to the chamber wall by screws welded to it and nuts that match the screws, making it easy to assemble and disassemble.

[0014] The decorative cover is equipped with a flat lock for opening and closing the cover, which facilitates cleaning, maintenance and replacement of the light source components and prevents unauthorized personnel from performing abnormal operations.

[0015] Compared with the prior art, the advantages of this utility model are:

[0016] The sterile isolator of this invention places the lamp source component on the outside of the chamber wall, so that the service life of the lamp source component is not affected by the hydrogen peroxide gas during sterilization inside the isolator; the lamp source component is located on one side below the flow equalization membrane, so the light is not blocked by the flow equalization membrane, effectively ensuring the lighting environment inside the sterile isolator; when the lamp source component needs to be replaced, it can be disassembled and replaced from the outside without disassembling the flow equalization membrane, making replacement more convenient and reducing maintenance costs.

[0017] The chamber wall is equipped with a locking assembly. A sealing gasket and a light-transmitting plate are arranged in sequence outside the light-transmitting opening. The light-transmitting plate is pressed onto the sealing gasket by the locking assembly to lock it, ensuring that the light-transmitting opening is completely sealed and preventing the light-transmitting position from damaging the sterile environment requirements inside the sterile isolator. At the same time, since the lamp source assembly is outside the isolator, there is no need to run wires from inside the isolator to the outside, making the inside of the isolator a fully enclosed chamber.

[0018] The light source assembly is installed inside the housing, which blocks external light sources to avoid excessive light pollution. The light source assembly is installed on the mounting part that slopes downwards towards the outside of the isolator. The LED lights of the light source assembly are installed at an angle downwards towards the inside of the isolator, so that the light source is dispersed into the chamber below the flow equalization membrane inside the isolator, providing a lighting environment for the operators. The light source assembly can be installed at corresponding positions on the walls of multiple chambers to effectively ensure the lighting environment inside the sterile isolator.

Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0025] like Figures 1 to 4The sterile isolator shown includes a chamber wall 1, with a light-transmitting opening 2 on the upper side of the chamber wall 1. The light-transmitting opening 2 is located on one side below the flow equalization membrane 3. A locking assembly 4 is provided on the outside of the chamber wall 1. A light-transmitting plate 5 is provided on the light-transmitting opening 2. A sealing gasket 6 is provided around the light-transmitting opening 2. The sealing gasket 6 is located between the light-transmitting plate 5 and the chamber wall 1. The light-transmitting plate 5 and the sealing gasket 6 are connected to the chamber wall 1 by the locking assembly 4. A cover 7 is provided on the outside of the light-transmitting plate 5. The cover 7 includes a mounting part 8 that slopes downwards towards the outside of the isolator. A lamp source assembly 9 is mounted on the mounting part 8.

[0026] The light source assembly 9 is located outside the chamber wall 1. The light-transmitting plate 5 is pressed onto the sealing gasket 6 and then locked by the locking assembly 4, making the isolator chamber a fully enclosed compartment. The sealed light-transmitting plate 5 isolates external particles and microorganisms, achieving zero contamination risk within the isolator. The light source assembly 9 is installed inside the housing 7. During routine cleaning, only the outer surface of the housing 7 and the metal connection structure need to be cleaned, avoiding frequent replacements due to material aging caused by the sterilization process inside the isolator, thus reducing maintenance costs. After passing through the light-transmitting plate 5, the light shines inward and downward (indicated by arrows) for illumination and signal display, ensuring an illuminance of 500 lux on the visible surface within 1 meter of the light source.

[0027] The locking assembly 4 includes a screw 10 welded to the chamber wall 1 and a nut 11 that matches the screw 10. The screw 10 passes through the sealing gasket 6, the light-transmitting plate 5, and the washer 12 to connect to the nut 11. The screw 10 is an energy-storing weld stud. The nut 11 is a cap nut. The connection is secure and not easy to loosen through the combined action of the washer 12 and the nut 11.

[0028] The side of the housing 7 is provided with an opening 13, which can be used to pass the wires of the lamp source assembly 9.

[0029] The outer casing 7 is provided with a decorative cover 14. The bottom of the decorative cover 14 is inclined and connected to the chamber wall 1, connecting the decorative cover 14 with the casing 7 and the chamber wall 1. The light source component 9 is hidden by the decorative cover 14, and the LED light and wires of the casing 7 and the light source component 9 are not visible from the outside. The inclined slope and the smooth surface of the decorative cover can reduce dust accumulation and facilitate cleaning in the room where the equipment is installed. From the appearance, it is aesthetically pleasing.

[0030] A laminar flow assembly 15 is provided above the chamber wall 1. The laminar flow assembly 15 includes a fan, a filter, and a flow equalization membrane 3. In order to meet the requirement of laminar flow blowing from top to bottom, the laminar flow assembly 15 is set above the chamber wall 1, and the lamp source assembly 9 is set on one side below the flow equalization membrane 3. This avoids adjusting the position of the laminar flow assembly 15 to install the lamp source assembly, thereby increasing the design cost and verification cost, and also avoids the laminar flow assembly 15 blocking the light illumination effect.

[0031] The light-transmitting panel 5 is made of PC board, and the sealing gasket 6 is made of foamed silicone gasket, achieving both sealing performance and good protective performance. The light-transmitting panel 5, made of PC board, has a light transmittance of 90%, similar to tempered glass. It not only meets the requirements of withstanding the corrosion of high concentrations of hydrogen peroxide gas in the biological purification mode of the sterile isolator, but also has an impact resistance 20 times that of tempered glass. It is not easy to break when subjected to accidental heavy impact. The density of the PC lampshade is only half that of glass, which greatly reduces the structural load and lowers transportation and installation costs. Even if it breaks, it will produce blunt-angled particles or no fragments flying, ensuring personnel safety.

[0032] The cover 7 is locked to the chamber wall 1 by screws welded to it and nuts that match the screws. The cover 7 can be removed from the chamber wall 1 to replace the lamp source assembly installed inside the cover 7. Since the lamp source assembly 9 is installed at a high height, it is more convenient to replace the lamp source assembly 9 by removing and installing the cover 7 than to pass the LED light out from the opening 13.

[0033] The decorative cover 14 is equipped with a flat lock for opening and closing the decorative cover 14. The decorative cover 14 can be opened to facilitate cleaning, maintenance, repair or replacement of the light source components. The flat lock on the decorative cover prevents unauthorized personnel from operating it and effectively ensures personnel safety. For example, it prevents the removal of the locking component 4 to open the light-transmitting opening 2 during the sterilization of the isolator, which could lead to high concentrations of hydrogen peroxide gas that could damage human health.

[0034] Inspecting the interior of the cavity through the isolator's viewing window reveals a smooth connection between the inner wall and the light source structure. The PC board structure exhibits a thickness step that fits snugly against the inner wall of the cavity, with no visible structural gaps or assembly marks. The cavity interior is clean, with a smooth surface and no visible particle or process residue. The wiring system employs a concealed design, with all cables routed through the outer wall of the cavity, resulting in no exposed wiring from the inside. The only visible element is the integrated LED light source, whose light creates uniform, shadowless illumination within the cavity.

[0035] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make many possible variations and modifications to the present invention, or modify it into equivalent embodiments, without departing from the scope of the present invention. Therefore, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention, without departing from the content of the present invention, should fall within the protection scope of the present invention.
