As shown in FIGS. 6 to 10, the filter device 100 of the present invention coupled as described above is a known exhaust hose 102 in a state in which the suction protrusion 142 of the suction unit 140 is fitted. By this method, harmful gas generated from the patient during surgery is introduced through the exhaust hose 102 .

And, the noxious gas introduced through the suction protrusion 142 of the suction unit 140 is transferred to both sides through the distribution passage 144 in a distributed state.

And, the harmful gas transferred through the distribution passage 144 forms a state in which one side is opened by the opening and closing protrusion 166 of the opening/closing means 164, so that the harmful gas is coupled to the coupling groove 162-1. It is introduced into the bag body 192 through the inlet protrusion 198 of the 190 and is filtered by the filter bag 190 .

Of course, the other side of the distribution passage 144 is blocked by the opening/closing protrusion 166 of the opening/closing means 164, so harmful gas does not flow into the filter bag 190 provided on the other side. Contamination of the filter bag can be prevented.

In addition, it is possible to prevent in advance external exposure of harmful gases that may occur in the opening and closing means 164 by the sealing bar 172 and the sealing piece 176 of the closing member 170 provided in the opening and closing means 164 . .

As described above, the noxious gas introduced into the filter bag 190 on one side causes the filter member 200 provided on the outside of the bag body 192 by the space formed by the support pillar 196 provided on the bag body 192 . It is discharged into the filter device 100 through the bag 204 in a filtered state,

The filtered gas discharged into the filter device 100 is discharged to the outside through the discharge hole 222 of the front cover 220, so that it is possible to easily filter the harmful gas generated during surgery.

In addition, the filter member ( 200) can be prevented from external exposure and escape.

As described above, the harmful gas is filtered in a certain amount or more in the filter bag 190 on one side, and in the case of a long operation, it is often insufficient due to filtering by one filter bag 190,

The filtering effect is reduced due to the luster of the filter member 200 filled in the filter bag 190 when the harmful gas of a certain capacity or more is filtered.

Accordingly, the present invention provides a simple sliding transfer means 240 to the other side without replacement of the filter device 100 by the filter bag 190 with reduced filtering effect and operation for a long time, so that the filter bag 190 is not replaced. It is possible to achieve filtering of harmful gas by another filter bag 190 fixed to the filter device 100 .

At this time, when the opening and closing means 164 is transported along the transport groove 162 to the other side by the transfer of the sliding transport means 240 , the distribution passage 144 on one side is blocked by the opening and closing protrusion 164 , and the other side By opening the distribution passage 164 of the toxic gas into the filter bag 190 on the other side, filtering can be achieved.

In addition, the opening and closing member is transported in a sealed state by the sealing member provided in the opening and closing member, and the filter bag closed by the transferred opening and closing member is closed and the filter bag with poor filtering effect is closed, so that the unfiltered harmful gas is removed. Emissions can be prevented in advance.

Therefore, the filter device according to the present invention can filter the harmful gas by introducing the harmful gas into the filter bag on the other side by transferring the sliding transfer means without replacing the filter bag. It can filter out harmful gases.

In addition, since the filter bag is not exposed to the outside by the combination of the main body and the front cover, it is possible to prevent damage due to external impact in advance.

In addition, when replacing a filter bag with poor efficacy, it is easy to replace the filter bag simply by disassembling the front cover.

Of course, in the filter device according to the present invention as described above, two or more filter bags may be built-in according to the user's selection.

In the filter device according to the present invention, it is preferable that the discharge hose 102 fitted to the suction unit is provided with an adjustment member 260 for controlling the amount of harmful gas discharged to the inlet unit 140 .

As an example, the adjusting member is provided in a roller-type or cylindrical shape capable of finely adjusting the amount of infusion injected when injecting an infusion into a patient, so that the amount of harmful gas discharged during surgery can be finely adjusted.

And, it is preferable that the main body and the front cover constituting the filter device according to the present invention are provided to emit far-infrared rays,

As an example, the main configuration of the filter device includes a known material such as ceramic that can emit far-infrared rays during injection molding, thereby maximizing the filtering environment of harmful gases and a favorable surgical environment during surgery.

What has been described above is only one embodiment for implementing the harmful gas filter device for surgery of the present invention, and the present invention is not limited to the above-described embodiment, and departs from the gist of the present invention as claimed in the following claims.
