Description

  The present invention relates to a safety cabinet having a negative pressure working space inside.

  Preparation work of drugs and infusions performed by workers such as pharmacists must be performed in aseptic conditions. Conventionally, in medical facilities such as university hospitals, there is a safety environment that has a working space filled with clean air. It was equipped with a cabinet, and the workers were doing the blending work in the work space. And when a conventional safety cabinet handles toxic drugs (especially toxic drugs such as antineoplastic drugs), the working space is in a negative pressure state so that air containing toxic drugs does not flow out to the worker side. Thus, the safety of the worker was ensured (see Patent Document 1).

  Conventionally, however, a computer has been used to manage and verify information necessary for an operator to perform preparation work (for example, drug type, preparation amount, patient data, etc.). Peripheral devices (keyboard, monitor, etc.) are installed outside the safety cabinet, and it is cumbersome and time consuming to operate the computer outside the work space of the safety cabinet and to carry out compounding work inside. It took a lot of work.
