Problems solved by technology

However, as far as the current transfer window is concerned, when the item is transferred, the item is placed directly inside the transfer window, and another person takes it out from the other side. When the item is located inside the transfer window, it is irradiated or air shower There will be dead angles during sterilization
In addition, the opening method of the transfer window is to manually open the door lock to pick and place items, and the experimenters have more hands to touch the items, which makes it difficult to ensure the cleanliness of the laboratory, which will cause potential pollution risks

Abstract

The invention provides a transfer window for high-grade biological safety laboratory, which belongs to the technical field of transfer window for biological laboratory. The invention includes a bracket, the inner bottom side of the bracket is rotatably connected with pedals, the pedals are provided at two places, and the two pedals are respectively rotatably connected to the front and rear sides inside the bracket, and the inner bottom ends of the two brackets are also fixedly connected with PLC controller, two PLC controllers are located under the two pedals respectively, and buttons are installed on the top of the two PLC controllers. The drive of the motor C makes the fan tilt, and the dust on the fan is shaken off to the inner position of the transfer box for storage through the tilt of the fan, thereby achieving a more practical purpose, and solving the problem that the existing transfer windows are opened manually. potential pollution problems.

Description

technical field [0001] The invention belongs to the technical field of transfer windows for biological laboratories, and in particular relates to a transfer window for high-grade biological safety laboratories. Background technique [0002] According to the biosafety protection level of the laboratory, the biosafety laboratory is divided into first-level (Biosafety Level, BSL-1), second-level (BSL-2), third-level (BSL-3) and fourth-level (BSL-4) ); ABSL-1, ABSL-2, ABSL-3 and ABSL-4 respectively represent the biosafety protection level of laboratories engaged in live animal operations. High-level biosafety laboratories refer to laboratories with protection levels of biosafety levels 3 and 4, which are used to carry out internationally recognized risk levels 3 and 4 (domestic recognized as the first and second types of pathogenic microorganisms) Scientific research on highly pathogenic microorganisms [World Health Organization. Laboratory Biosafety Manual [M] 3rd edition. Gen...
