- workers who entered the working room 2 can sterilize their hands with the sterile hand-washing machine 78. Workers perform this dust removal and sterilization, and the force also performs dispensing work.
- the air conditioning system 4 is switched to the positive pressure working mode or the negative pressure working mode, and then the operator in the working room 2 puts his hand into the working space 21 from the working opening 22 and then on the working table 20. Can perform dispensing work.
- the air conditioning system 4 when the air conditioning system 4 is set to the positive pressure working mode, the working room 2 becomes positive pressure and the outside air does not enter into the working room 2, so that the normal medicine dispensing operation is performed. Suitable for In addition, when the air conditioning system 4 is in negative pressure work mode, the work room 2 is under negative pressure, and the air in the work room 2 does not leak to the outside, so dispensing of an anticancer drug (strong drug) It becomes suitable for work.
- an anticancer drug strong drug
- the air conditioning system 4 should be in the ventilation mode and the work room 2 and the clean bench unit 3 must be forcibly ventilated. Can.
- the clean room unit 1 by providing the working room 2, the clean room unit 3, the air conditioning system 4, and the control unit 5, the worker enters the working room 2 and then the air in the working room 2. You can take a shower and then use the clean bench unit 3 in the work room 2 to perform dispensing operations, and an environment suitable for performing the dispensing operations. It is possible to make S.
- the air conditioning system 4 can generate an air shower, it is not necessary to separately provide an air shower apparatus.
- the working room 2 can be configured to be small enough to allow only one worker to enter and perform dispensing operations, and the air conditioning system 4 can be miniaturized. As a result, downsizing and cost reduction of the clean room unit 1 can be realized.
- the clean room unit 1 can be miniaturized and the clean room unit 1 can be installed independently inside the building, the conventional clean room, which makes it easy to secure the installation place of the clean room unit 1 in a medical facility, It is possible to provide a very useful clean room unit 1 which can replace the room (air shower unit) and the tarine bench.
