At the same time, the airflow in the dispensing room also flows from the inside to the operation window, so it also effectively prevents the air outside the dispensing room from flowing into the dispensing room and polluting the medicines.

In the example of FIG. 1 , the isolating device 2 is provided with a flow guide groove 23 along the edge of the operation window, and the flow guide groove 23 communicates with the exhaust port, and is used to guide the air flow forming the air curtain to pass through the flow guide groove 23 and the exhaust port. exhaust vent.

In the example shown in FIG. 1 , a plurality of exhaust holes 24 are provided on the guide groove 23 , and these exhaust holes 24 communicate with the exhaust ports through pipelines. Thus, the air curtain air flow fan-shaped to the left and right and upwards, and the exhaust holes 24 are arranged reasonably to form negative pressure at the four edges of the operation window, and cooperate with the air curtain to further isolate the environment inside and outside the dispensing room.

In some other embodiments, at least one guide fin is set in the guide groove 23, and the guide fin can be rotated. When there are two guide fins, one of them is biased toward the inside of the dispensing chamber, and the other is biased toward the dispensing chamber. On the outside of the room, the air inside the dispensing room is sucked away by the negative pressure device from the gap between the inner guide fins and the guide groove 23 (vacuum pumps, vacuum cleaners and the like can be used), and the air outside the operating window The gap between the diversion fins and the diversion groove 23 flowing to the outside is sucked away, and between the inside and outside air, and the air curtain gas are also sucked away from the diversion groove by the negative pressure device.

In practical application, the exhaust hole or the exhaust port communicates with the air pump.
