Description

Technical Field

[0001] This utility model relates to the field of clean operating room material transfer technology, and in particular to an intelligent transfer window that can monitor cleanliness in real time. Background Technology

[0002] Traditional pass-through windows in pharmaceutical cleanrooms are only used for material transfer. The resistance of the internal filters can only be observed through local differential pressure gauges, and the cleanliness of the remote environment (such as particle count and differential pressure) cannot be monitored in real time. Operators need to manually check periodically or rely on external sensors, which results in monitoring lag. Furthermore, frequent window opening for inspection may lead to contamination of the clean environment, affecting the safety of drug production. Utility Model Content

[0003] The technical problem this invention aims to solve is that traditional pass-through windows cannot monitor the cleanliness of the remote transmission area in real time, rely on external sensors for operation, have monitoring lag, and frequent window opening for testing may lead to contamination of the clean environment, affecting the safety of drug production.

[0004] The technical solution adopted by this utility model to solve its technical problem is: an intelligent transfer window that can monitor cleanliness in real time, including a fixed frame, a transfer cavity with front and rear openings at the lower end of the fixed frame, a tempered glass window with a self-locking module hinged to the front and rear openings of the transfer cavity, an n-shaped filter chamber with a detachable high-efficiency filter installed inside the fixed frame and located around the transfer cavity, a laser particle counter installed on the top surface of the transfer cavity, high-precision differential pressure sensors installed on the bottom surface of the transfer cavity and the outside of the fixed frame, an ultraviolet germicidal lamp installed on the inner wall of the transfer cavity, and a status touch display screen installed on the outer wall of the fixed frame.

[0005] An electric air circulation pump is installed inside the fixed frame on the filter chamber.

[0006] The inner wall of the transfer cavity is provided with an outwardly recessed mounting groove, and the ultraviolet germicidal lamp is fixedly installed inside the mounting groove. The light guide surface of the ultraviolet germicidal lamp is located on the same plane as the inner wall of the transfer cavity.

[0007] Silicone sealing strips are installed on the inner walls of the openings on both sides of the transmission cavity.

[0008] The lower end of the filter chamber is connected to the inside of the transfer chamber via a flow guide.

[0009] An external control handle is installed on the side wall of the tempered glass window.

[0010] The beneficial effects of this utility model are:

[0011] (1) The present invention provides an intelligent transfer window that can monitor cleanliness in real time. It integrates a particle counter, a differential pressure sensor and a data display module to monitor and display the cleanliness parameters inside the window in real time. At the same time, it is linked with the cleanroom control system. When the cleanliness exceeds the standard, it will automatically alarm and lock the transfer window to prevent the spread of pollution.

[0012] (2) By opening an n-shaped filter chamber inside the fixed frame and outside the transfer chamber, a detachable high-efficiency filter is installed inside the filter chamber, which can efficiently filter the air inside the transfer chamber. Combined with the ultraviolet germicidal lamp set on the inner wall, the internal cleanliness is greatly improved. Attached Figure Description

[0016] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Figure 1 and Figure 2The diagram illustrates an intelligent transfer window capable of real-time cleanliness monitoring. It includes a fixed frame 1, with a transfer chamber 2 having front and rear openings at the lower end of the fixed frame 1. The inner wall of the transfer chamber 2 is made of 316L stainless steel with an electrolytic polishing treatment to prevent dust accumulation and microbial growth. The front and rear openings of the transfer chamber 2 are hinged to tempered glass windows 3 equipped with self-locking modules, which are electromagnetic locks. An n-shaped filter chamber 4 is located outside the transfer chamber 2 within the fixed frame 1. A removable high-efficiency particulate filter 5 (HEPA) with a filtration efficiency ≥99.99%@0.3μm is installed inside the filter chamber 4, ensuring unidirectional clean airflow within the transfer chamber 2. A laser particle counter 6 is installed on the inner top surface to monitor the concentration of particles with a diameter of 0.5μm and above in real time. High-precision differential pressure sensors 7 are installed on the inner bottom surface of the transfer chamber 2 and the outer side of the fixed frame 1 to monitor the pressure gradient between the transfer window and the clean room. An ultraviolet germicidal lamp 8 is installed on the inner wall of the transfer chamber 2, which automatically starts the sterilization program during non-transfer periods and can also support timed or remote control. A status touch screen 9 is installed on the outer wall of the fixed frame 1. The status touch screen 9 displays real-time data and receives data from the laser particle counter 6 and the high-precision differential pressure sensor 7, including: particle count, pressure difference, temperature and humidity (with the addition of existing temperature and humidity sensors). It supports historical data query and export (with built-in existing storage module).

[0019] The laser particle counter 6, the high-precision differential pressure sensor 7, the ultraviolet germicidal lamp 8, and the status touch display screen 9 are all existing technologies.

[0020] The fixed frame 1 can also be equipped with a wireless communication module of existing technology, such as Wi-Fi / Bluetooth, to synchronize data to the cleanroom central monitoring system;

[0021] It can also trigger an existing audible and visual alarm when the value exceeds the standard, with a buzzer of ≥80dB and a flashing red LED, and automatically lock the double tempered glass window 3 by controlling the existing electromagnetic lock to prevent accidental operation.

[0022] An electric air circulation pump 10 is installed inside the fixed frame 1 on the filter chamber 4.

[0023] The inner wall of the transfer chamber 2 is provided with an outwardly recessed mounting groove. The ultraviolet germicidal lamp 8 is fixedly installed inside the mounting groove, and the light guide surface of the ultraviolet germicidal lamp 8 is located on the same plane as the inner wall of the transfer chamber 2.

[0024] To improve sealing, silicone sealing strips are installed on the inner walls of the openings on both sides of the transmission cavity 2.

[0025] To facilitate import and export, the lower end of the filter chamber 4 is connected to the interior of the transfer chamber 2 via a guide port.

[0026] For ease of control, an external control handle 31 is installed on the side wall of the tempered glass window 3.

[0027] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
