Description

  The present invention relates to a work table for pathological examination, a system examination table for pathological examination, and an examination method.

In the pathology laboratory, a microscope specimen is prepared from organs, tissues, cells, and the like collected for the purpose of surgery or examination, and a detailed diagnosis is performed using a microscope or the like. In pathological examinations, organic chemicals such as formalin (formaldehyde aqueous solution) and xylene are used. Regarding such organic chemical substances, the regulation for the prevention of specific chemical substances sets the indoor control concentration of formaldehyde to 0.1 ppm.
Therefore, it is desirable that the work table for pathological examination has a function of suppressing diffusion of organic chemical substances. For example, Patent Literature 1 discloses a first air supply unit that supplies gas from the front side to the back side of the sink, and a second air supply unit that supplies gas obliquely from above the back side of the sink toward the front side of the sink. A sink is disclosed that forms an air curtain above the sink by using two air supply units and an exhaust unit that exhausts from the back side of the sink to prevent volatile substances in the sink from diffusing.
In addition, Patent Literature 2 discloses a sink that sucks and exhausts gas in the sink from a suction port provided in a lower portion of a side surface of the sink to prevent volatile substances in the sink from being diffused.

JP 08-001124 A JP 2018-004189 A

Organic chemicals such as volatilized formaldehyde are heavier than the atmosphere, and therefore easily stay in the sink. Even when exhausting from the side of the sink or shielding with an air curtain, etc., when working inside the sink where organic chemicals have accumulated, the gas in the sink is agitated and extracted from the sink There is a risk that organic chemicals in the sink may leak to the outside together with the arm and sample of the medical staff.
An object of the present invention is to solve the above-described problems, and a path for a pathological examination work table, a pathological examination system examination table, and a pathological examination method that can more reliably prevent leakage of organic chemical substances. It is an object to propose an inspection method using a system inspection table.

The invention according to claim 1 is a pathological examination comprising a sink, a receiving tank provided below the sink, a drain pipe connected to a bottom surface of the receiving tank, and an exhaust pipe connected to a side surface of the receiving tank. Work table. The receiving tank is connected to the bottom surface of the sink so that liquid and gas can flow down, and a gas heavier than the atmosphere flows down to the receiving tank and is exhausted from the receiving tank via the exhaust pipe.
The invention according to claim 2 is a pathological examination system examination table in which a plurality of work tables with different applications are arranged side by side. A pathological examination system examination table has a hood that covers the upper part of the work table, a horizontal plate that divides the space in the hood into an upper space and a lower space, and a gap from an inner wall on the back side of the work table. And a vertical plate provided.
The hood is cantilevered on the back side of the work table or suspended above the work table, and there is no hood support means on the near side of the work table. Therefore, it is possible to move from the work table to the next work table without taking out the inspection target. Leakage of organic chemicals and the like can be prevented by laterally moving the sample or the like without removing it.
Further, at least a part of the plurality of worktables includes a sink, a receiving tank connected to a bottom surface of the sink, and an exhaust pipe connected to the receiving tank, and an upper surface of the worktable and the partition plate. The vertical plate is provided with an exhaust gallery, the exhaust pipe is connected to an exhaust hole formed in the vertical plate, and a gap between the vertical plate and the inner wall is The upper space is connected to an exhaust duct. Therefore, since the organic chemical substance is exhausted through the exhaust duct, the diffusion of the organic chemical substance into the pathological examination room is prevented.
In the pathological examination system examination table according to claim 3, since the exhaust port is formed in the vertical plate facing the space below the work table, an organic compound is formed under the work table. Even if the quality leaks out, it can be prevented from spreading in the pathological examination room.
Further, an invention according to claim 4 is an inspection method using the pathological inspection system inspection table according to claim 2 or 3, wherein the inspection table is one of a plurality of the operation tables. By moving the used sample laterally to another work table without taking it out of the pathological inspection system inspection table, gas leakage from the pathological inspection system inspection table is prevented.

According to the pathological inspection work table and pathological inspection system inspection table of the present invention, a gas heavier than the atmosphere is guided to the receiving tank provided below the sink, so that the gas does not stay in the sink. Therefore, it is possible to prevent the organic chemical substance from leaking out of the sink. In addition, the backflow of the odor from the liquid stored in the trap below the sink can be prevented.
Further, according to the pathological examination system work table and the test method using the same according to the present invention, since the support means such as the cubicle is not present in front of the work table in the hood, the specimen or the like is moved between the work tables. In this case, there is no need to extract the sample. Therefore, it is possible to prevent the organic chemical substance from leaking to the outside together with the sample.

It is a top view showing the pathology examination room of this embodiment. It is a perspective view which shows a part of system examination table for pathology examinations. It is sectional drawing which shows the workbench for pathological examination.

In the embodiment of the present invention, a system examination table 1 for pathological examination provided in a pathological examination room R of a medical facility will be described. As shown in FIG. 1, a pathological examination system R for the present embodiment is provided with a pathological examination system examination table 1. The pathological inspection system inspection table 1 includes a plurality of pathological inspection work tables 2 having different uses. In the present embodiment, the pathological examination room R which is more excellent in workability and more secure is formed by constructing the pathological examination system examination table 1 together with the building as auxiliary equipment of the building. The pathological inspection system inspection table 1 employs a push-pull method that allows a specimen to be moved laterally between pathological inspection work tables 2. This prevents organic chemicals such as formalin and xylene used for the specimen from leaking out of the apparatus (pathological examination system examination table 1).
The pathological inspection system inspection table 1 according to the present embodiment includes, as a pathology inspection work table 2, a work table 2a, a sink 2b, an imaging table, a cutting table, a waste liquid table, and the like. That is, the pathological inspection system inspection table 1 includes a plurality of work tables (pathological inspection work tables 2) arranged in parallel for different purposes. The pathological examination system examination table 1 also includes a paraffin embedding device, an organ storage, and the like. In addition, the number and types of the pathological inspection work tables 2 included in the pathological inspection system inspection table 1 and other equipment and devices are not limited.

As shown in FIG. 3, a vertical plate 3 provided with a gap from the inner wall W (the wall of the pathological examination room R) is provided on the back side of the pathological work table 2. The upper part of each pathological work table 2 is covered with a hood 4.
The hood 4 is cantilevered by the inner wall W. That is, the hood 4 protrudes from the upper rear side of the pathological examination work table 2, and a column (a side) for supporting the hood 4 is provided on the near side (the opposite side to the inner wall W) of the pathology examination work table 2. No standing wall or support wall is provided under the hood 4. In addition, the hood 4 may be suspended by a ceiling, beams, or the like above the pathological work table 2. The hood 4 includes a hood main body 41 and an elevating sash 42 provided on the front side of the hood main body 41.
The hood main body 41 includes a top plate 43 extending from the inner wall W, a front plate 44 extending downward from a front end of the top plate 43, and a side plate 45 (see FIG. 2) that covers a side surface. That is, the hood main body 41 covers the upper surface, the front surface, and both side surfaces of the space above the pathological work table 2. Note that the top plate 43 may be provided as needed. That is, the top plate 43 may be omitted as long as the gap with the ceiling can be shielded. Further, the side plate 45 may be omitted except for the hood 4 above the pathological work table 2 arranged at the end of the pathological test system test table 1. The front plate 44 of the present embodiment is inclined with respect to the vertical plane so as to move away from the inner wall W as it goes downward. Note that the front plate 44 may be parallel to the inner wall W. The lifting sash 42 is provided on the front plate 44 so as to be vertically movable. The lifting sash 42 moves downward from the lower end of the front plate 44 in parallel with the extension of the front plate 44, thereby adjusting the size of the opening area on the front side of the pathological examination work table 2. The elevating sash 42 includes a glass plate, and is interposed between a work space A1 that is a space above the work table 2 for pathological examination and a medical worker who performs a pathological examination. The medical practitioner works while inserting his or her hand into the work space A1 from under the elevating sash 42 while visually checking the inside of the work space A1 via the elevating sash 42. The lifting sash 42 contacts the front side of the upper surface of the pathological work table 2 with the sash 42 lowered to the lowest position. The lifting sash 42 does not necessarily have to have a size that is in contact with the pathological work table 2. Further, it is not always necessary to use a glass plate for the lifting sash 42, and for example, a transparent acrylic plate may be used.

  The hood 4 is provided with a horizontal plate 5 that divides a space in the hood 4 (a space surrounded by the top plate 43, the front plate 44, and the inner wall W) into an upper space A2 and a lower space A3. An exhaust duct (not shown) is connected to the upper space A2, and the upper space A2 is configured to be able to exhaust air. In the present embodiment, the air supply unit 6 is provided on the horizontal plate 5. The air supply unit 6 forms a downward airflow in the work space A1 on the pathology inspection workbench 2 by blowing air downward. The air supply unit 6 may include a louver (not shown) that divides the airflow along the elevating sash 42 and the airflow directed downward. In this way, a so-called air curtain is formed by the airflow along the lifting sash 42, so that it is difficult for gas to leak out of the apparatus. Note that the air supply unit 6 may be provided as needed.

The vertical plate 3 is fixed to the inner wall W via a support member (not shown). The support member supports the vertical plate 3 at a predetermined distance from the inner wall W. The method of supporting the vertical plate 3 is not limited, and for example, the vertical plate 3 may be erected from the floor.
Between the vertical plate 3 and the inner wall W, a permeable space (aeration space A4) is formed. The upper end of the vertical plate 3 is in contact with the lower surface of the horizontal plate 5. The horizontal plate 5 has a ventilation hole 51 formed on the inner wall W side, and a ventilation space A4 (a gap between the vertical plate 3 and the inner wall W) is connected to the upper space A2 via the ventilation hole 51. The gas flowing into the upper space A2 from the ventilation space A4 is exhausted through the exhaust duct.
The vertical plate 3 is provided with an exhaust gallery 31 facing the work space A1 between the upper surface of the pathological work table 2 and the horizontal plate 5. The exhaust space 31 allows the work space A1 to be exhausted. In this embodiment, the exhaust gallery 31 is provided in two stages vertically, but the number and arrangement of the exhaust gallery 31 are not limited. Further, the vertical plate 3 is formed with an exhaust port 33 (for example, an exhaust gallery) facing a space below the pathological work table 2 (under-table space A5).

The workbench 2 for pathological examination according to the present embodiment includes a sink 21, a receiving tank 22 provided below the sink 21, a trap 26 connected to a bottom surface of the receiving tank 22, a drain pipe 23, and a side surface of the receiving tank 22. And an exhaust pipe 24 connected thereto.
The sink 21 is a water tank-shaped recess. An opening connected to the receiving tank 22 is formed at the bottom of the sink 21. A net or the like is provided in the opening formed on the bottom surface of the sink 21 as necessary. By doing so, it is possible to prevent the sample or the like from dropping into the receiving tank 22 while causing the liquid or gas in the sink 21 to flow down to the receiving tank 22. At the opening on the upper surface of the sink 21, a work plate (work plate 25) for work is laid as needed. It is desirable that the work plate 25 be a perforated plate having the strength necessary for performing the work and having many holes penetrating therethrough. The material of the work plate 25 is not limited, and for example, a plate made of stainless steel may be used.
The receiving tank 22 temporarily receives the liquid and gas flowing down from the sink 21. The receiving tank 22 has a smaller volume than the sink 21. An exhaust pipe 24 is connected to the receiving tank 22. The exhaust pipe 24 is connected to an exhaust hole 32 formed in the vertical plate 3. The exhaust pipe 24 guides the gas in the receiving tank 22 to the ventilation space A4. A gas (e.g., a vaporized organic chemical substance) that is heavier than the atmosphere flows down from the work space A1 to the sink 21, and then flows from the inside of the sink 21 to the receiving tank 22. The gas flowing down to the receiving tank 22 is exhausted from the receiving tank 22 through the exhaust pipe 24 to the ventilation space A4, then guided to the upper space A2, and exhausted through the exhaust duct. Therefore, the organic chemical substance or the like does not stay in the receiving tank 22.
A drain pipe 23 is connected to the bottom of the receiving tank 22 via a trap 26. The drain pipe 23 discharges the liquid flowing down from the sink 21 to the trap 26 via the receiving tank 22. Therefore, the liquid containing the organic chemical substance or the like does not stay in the receiving tank 22. Further, since the odor emitted from the liquid stored in the trap 26 is discharged from the exhaust pipe 24, the odor is prevented from flowing into the work space A1 (backflow). Note that the trap 26 may be provided as needed.

An example of an examination procedure using a path work system work table is shown below.
First, after the collected sample is washed with the sink 2b, the sample is imaged on the imaging table using the organ imaging apparatus. Next, after the sample is cut out to a predetermined size by the cutting table, alcohol is removed by dehydration and degreasing in the waste liquid table. After that, the paraffin is embedded in a paraffin embedding apparatus. Next, the sample is sliced on the cutting table, and the sample is spread on the work table 2a and adhered to a slide glass for staining. Then, the tissue section is covered with a mounting medium and a cover glass and stored in an organ storage. Thereafter, if necessary, the tissue section is diagnosed with a microscope.

As described above, according to the pathological inspection system inspection table 1 of the present embodiment, since there is no support member for the hood 4 in front of the pathological inspection work table 2, the pathological inspection operation table 2 (pathological inspection system inspection) is not provided. (In the table). That is, since the work spaces A1 of the adjacent pathological examination work tables 2 are continuous with each other, the specimen can be moved to another pathological work table 2 without removing the sample from the work space A1. Therefore, the specimen can be moved without being taken out of the pathological examination system examination table 1 to complete the examination. If the specimen is not taken out of the apparatus, it is possible to prevent the organic chemical substance and odor from leaking out of the apparatus together with the specimen.
Since the path inspection system inspection table 1 is also installed at the time of building construction, such as fixing the hood 4 to the inner wall W, the construction is easier than when the pathology inspection work table 2 is installed after the building construction. In addition, the degree of freedom of arrangement of each facility is high.

  Since a downward airflow is formed by the air supply unit 6, the gas in the work space A <b> 1 is guided to the receiving tank 22 via the sink 21. The gas flowing into the receiving tank 22 is guided to the ventilation space A4 on the back side of the vertical plate 3 via the exhaust pipe 24, and then flows to the upper space A2 to be exhausted from the exhaust duct. Therefore, the vaporized organic chemical substance is unlikely to leak outside the apparatus (in the pathological examination room R). Further, since the gas that is heavier than the atmosphere flows down to the receiving tank 22 via the sink 21, the organic substance does not stay in the work space A1 and the sink 21. Therefore, when the work is performed on the pathological work table 2, the organic chemical substance is unlikely to leak out of the apparatus.

Since the gas flowing down from the sink 21 to the receiving tank 22 is exhausted through the exhaust pipe 24, the gas does not flow backward from the receiving tank 22 side toward the work space A1. Further, since the liquid flowing down to the receiving tank 22 is drained through the drain pipe 23, the liquid does not stay in the receiving tank 22, and the organic chemical substance is vaporized in the receiving tank 22 and leaks to the working space A1 side. Nothing to do.
Since the exhaust gallery 31 is formed in the vertical plate 3, the gas is prevented from staying in the work space A1. That is, since the gas in the work space A1 flows down to the sink 21 or is exhausted from the exhaust gallery 31, the gas does not stay. Since the gas does not stay in the work space A1, it is possible to prevent the gas containing the organic chemical substance from leaking out of the apparatus.
Since the exhaust port 33 is formed in the vertical plate 3 so as to face the undercarriage space A5, even if gas leaks from the work space A1 to the undercarriage space A5, the gas is exhausted from the exhaust port 33.
Since the ventilation space A4 is connected to the exhaust duct via the upper space A2, an airflow toward the upper space A2 is formed in the ventilation space A4. Therefore, the gas flowing into the ventilation space A4 is exhausted without staying.

Although the embodiment according to the present invention has been described above, the present invention is not limited to the above-described embodiment, and each of the above-described components can be appropriately changed without departing from the spirit of the present invention.
The pathology work table 2 may be rearranged as necessary.
Each pathological work table 2 may be fixed to the inner wall W or floor of the pathological examination room R.
