Taking up system and process with a filter unit for the receiving of gas from a medical apparatus

A medical system comprising:

• a medical apparatus;
• and
• a taking up system comprising:
• a feed line configured to establish a fluid connection with the medical apparatus;
• a discharge line configured to establish a fluid connection with a fluid taking up unit or with a surrounding area;
• a filter unit comprising a filter, wherein the filter is configured to filter a predefined gas component out of a gas which is passed through the filter, wherein a respective fluid connection is established or is establishable between the feed line and the filter unit and between the discharge line and the filter unit;
• and
• a buffer storage device in a respective fluid connection with the feed line and/or in a respective fluid connection with the discharge line, the buffer storage device being configured to temporarily store gas from the feed line and/or from the discharge line and later to discharge same into the feed line and/or into the discharge line, wherein the taking up system is configured to:
• guide gas out of the medical apparatus through the feed line to the filter unit;
• pass the gas through the filter unit and at least partially through the filter;
• and
• guide the gas through the discharge line to the fluid taking up unit or into the surrounding area;
• the filter unit further comprises a filter mount enclosing an interior and being in a fluid connection with the feed line and in a fluid connection with the discharge line;
• the filter unit further comprises a plate movably arranged and fluid-tightly dividing the interior of the filter mount into a filter cavity and a buffer storage device cavity;
• the filter is inserted or is insertable into the filter mount;
• the filter cavity is configured to accommodate the filter;
• the buffer storage device cavity forms the buffer storage device or a portion of the buffer storage device or forms a further buffer storage device;
• and
• the buffer storage device cavity is in a fluid connection with the feed line and is in a fluid connection with the discharge line at least when no filter is inserted into the filter mount.

A process for the taking up of gas from a medical apparatus, the process comprising the steps of:

• providing a taking up system, wherein the taking up system comprises:
• a feed line;
• a discharge line;
• a filter unit comprising a filter and a buffer storage device;
• establishing a fluid connection between the medical apparatus and the feed line;
• establishing a fluid connection between the discharge line and a fluid taking up unit or a surrounding area;
• at least one of releasing, discharging and suctioning gas from the medical apparatus;
• guiding, with the taking up system, the gas through the feed line, the filter unit and the discharge line to the fluid taking up unit or into the surrounding area, wherein all the gas or at least some of the gas is guided through the filter during the passing through the filter unit;
• filtering, with the filter, a predefined gas component out of the gas, which is guided through the filter;
• temporarily storing gas in the buffer storage device when more gas is released from the medical apparatus than is sent into the fluid taking up unit or into the surrounding area by sending gas from at least one of the feed line and the discharge line into the buffer storage device;
• and
• releasing the temporarily stored gas by sending the temporarily stored gas from the buffer storage device into at least one of the discharge line and the feed line;
• the filter unit additionally comprising:
• a filter mount enclosing an interior and being in a fluid connection with the feed line at least from time to time and being in a fluid connection with the discharge line at least from time to time;
• and
• a plate arranged to be moveable and to fluid-tightly divide the interior of the filter mount into a filter cavity and a buffer storage device cavity, wherein:
• the filter is inserted into the filter cavity;
• the filter is removed from the filter mount at least one time;
• and
• the buffer storage device cavity is in a fluid connection with the feed line and in a fluid connection with the discharge line at least when the filter has been removed.
