Conventionally, as a device for handling substances and dangerous pathogens in clean air, an air supply is provided in a working chamber 101 equipped with a see-through window 108 and gloves 109 fixed to the device, as shown in FIGS. 1A and 1B. An air supply unit equipped with an air supply fan 103a and an air supply filter 105, and an exhaust unit equipped with an exhaust filter 106 and an exhaust fan 103b were respectively provided, and the system was constructed so that a sample could be handled in clean air. Also, as shown in FIGS. 2A and 2B, a glove 209 fixed to a see-through window 208 and the device is disclosed in the above publication.
A circulation filter 2 is placed inside the main body case, which is equipped with
Japanese Utility Model Publication No. 48-3673 discloses a device equipped with a circulation fan 203 and a circulation fan 203 and configured to handle a sample through gloves 209 in clean air. However, these devices have a problem in that workability is poor because the sample is handled through gloves fixed to the device. Therefore, the use of these devices has been limited to cases where extremely dangerous samples are handled. In the process of solving these problems, a technique of using an air curtain to insulate the working opening has been studied, and as an example, as shown in FIG. A clean workbench configured to form an air curtain airflow through the duct part of the shutter 317 and to be sucked in from the suction port 310 together with the remaining clean air that has flowed through the workroom 301.
It is disclosed in Publication No. 34959. The clean workbench shown in FIG. 3 has shutters 3 on both sides of the workroom 301.
17 is provided so that air curtains are formed on both sides. With such equipment, multiple workers can work together,
It also has the advantage of being able to work without using gloves that are fixed to the equipment, which improves work efficiency. There is a risk that the sample attached to the worker may be taken out of the workbench. In addition, it is necessary to supply the air volume for the air curtains installed on both sides of the workbench, and even if only one side is used, the equipment must ensure the air volume for both sides of the air curtains, which increases the size of the equipment. There are problems in that it is heavy and uneconomical for the user.

In addition, if the floor plate 11 is provided in a removable manner, the main body case 1
It is possible to easily remove debris from the sample that has accumulated on the bottom 19a of the sample. In this embodiment, the floor surface of the work room is divided into the suction port 10 and the plate 11.
As shown in FIG. 3A, a floor plate 11' may be formed integrally with a suction port 10 and a ventilation hole 11a.
Further, as shown in FIG. 13B, a floor plate 11' may be formed integrally with a suction port 10 and a ventilation hole 11a and a radius at the stepped portion. According to this, the accumulation of harmful substances, etc. at the stepped portion may be made. can be prevented. Further, the stepped portion may be formed at an obtuse angle instead of being rounded, which improves workability during molding. Furthermore, as shown in FIG. 13C, a duct 16 may be provided throughout the lower part of the floor plate 11'.

According to this, as shown in FIG. 12, even when performing work such as dissection of laboratory animals, contamination of the floor surface of the working room by blood and washing water can be kept to a minimum. In order to put the waste generated during work into the bag 20, an opening 11d is provided in the floor plate 11 as shown in FIG. 11A, and the opening 11 is
d may be normally covered with a lid 11c. Note that the lid 11c is supported from below by a seat plate 11b to prevent it from falling during use. Further, even in the case of a saucer-shaped floor surface 25, an opening 24a is provided as shown in FIG. 11B, and this opening 24a
The lid 24c may be supported by the seat plate 25b from below. To attach the bag 20 to the outlet 19b of the main body, fold the opening of the bag 20 inside the main body 19,
It may be tightened with an O-ring 21. Further, as shown in FIG. 11C, the area around the discharge port 19b' may be formed into a funnel shape, or furthermore, a water gradient may be provided across the bottom of the main body case as shown in FIG. 11D. According to this method, it is difficult for waste and disinfectant to accumulate inside the device, the interior can be easily cleaned, and no harmful substances remain inside the device, improving safety. To attach the bag 20 to the outlet 19b', attach the outlet 19b' to the bag 2.
0 and tighten it from the outside with a band 21'. In addition, as shown in FIG. 11E, the discharge port 19
A flange 19c is provided on the outer periphery of b', and a flange 20a provided at the mouth of the bag 20 may be fastened to this flange 19c. Furthermore, flange 2 of bag 20

Improves sex. When performing work such as dissection of laboratory animals using the clean workbench according to the present invention, workers A and B
Work efficiency is improved because people can work face to face. Furthermore, even if the skill level of the workers is different, it is possible to have the less skilled worker B perform the work through gloves, and at the same time, the highly skilled worker A can directly touch the hand through the work opening. Since you can put it in and work with it, your work efficiency will not be affected. Furthermore, according to the above-described embodiments of the present invention, even though work can be done from both sides, only one side of the air curtain is required, so the amount of air to be processed by the device can be reduced, and the device can be made smaller and lighter. At the same time, an economical clean workbench with low energy consumption can be obtained.
