[Problems to be Solved by the Invention]

(1) The dissection table in the conventional dissection facility has a structure in which water cannot be used. Therefore, the blood and blood glue generated from the corpse immediately solidified on the dissection table, and the solidified blood had to be scraped off during the dissection, which was a difficult and time-consuming task. Therefore, it is a first object of the present invention to provide an easy-to-use dissection facility which does not require extra work.

In recent years, many infectious diseases, such as AIDS virus, hepatitis virus and ATL, for which a complete cure has not been established yet, occur, and patients infected with them or patients who may be infected with them. Opportunities to dissect about are increasing. Also, the autopsy of patients infected with M. tuberculosis is increasing. Therefore, there is a risk that the person in charge of autopsy will be infected with AIDS, viral hepatitis, ATL, etc. at the time of autopsy. There is a growing demand and need to reduce the risk of infection by the person in charge of pathological dissection, and improvement of the dissection facility is also desired. In particular, for tubercle bacilli susceptible to airborne infection, sufficient measures must be taken to prevent infection. Regarding the infection at the time of autopsy, the main route of infection is considered to be direct contact with the patient, blood, body fluid, and dirt. In order to prevent infection by this direct contact, one of the applicants has already provided a new and useful dissection table (for example, Japanese Utility Model Application No. 1-
0336342). However, in order to prevent infections, it is necessary to prevent airborne infections caused by aerosols generated from autopsied specimens. This is especially important for Mycobacterium tuberculosis. Therefore, a second object of the present invention is to provide an anatomical facility capable of rinsing blood and the like generated from a corpse with water while at the same time preventing diffusion of an aerosol generated from the corpse.

[0004]

The object is to perform the anatomical facility according to claim 1, that is, a laminar flow air supply device provided on the ceiling above the dissection table and air-water separation type anatomical surface suction. This is achieved by an anatomy facility having a dissection table and a fan provided in an exhaust pipe of the dissection table.

In a preferred embodiment of the present invention, as described in claim 2, the dissecting table is provided with an upwardly convex arch-shaped cage child, an intake pipe, and an intake tube cover. An opening is provided slightly inside the periphery, a net is fitted into the opening, the inspiratory tube penetrates the bottom surface of the sink, the upper edge of the inspiratory tube projects above the bottom surface of the sink, and the lower edge of the inspiratory tube reaches the dissection table bottom surface. And the intake pipe upper edge opening is covered with a net, the intake pipe cover is disposed above the intake pipe, and the intake pipe upper edge opening is covered from above. To do.

In another preferred embodiment of the present invention, as described in claim 3, the dissecting table is divided into an upper part and a lower part, and the upper part of the dissecting table is moved up and down to increase the height of the dissecting table. It is provided with a mechanism for adjusting, and the intake pipe is characterized by including a bellows pipe portion.

[0007]

[Function] By the laminar flow air supply device, a laminar flow is always formed between the autopsy person and the autopsy subject, and the air diffusion of infectious pathogens generated from the autopsy subject is prevented, so that the autopsy person's air is prevented. It has a structure to prevent infection. In detail,
It is as follows. The baby cage forms the upper surface of the main table and side table of the dissecting table, and the autopsy specimen is placed in the center thereof. Then, the air in the dissection room is sucked in through the opening provided in the cage, exhausted to the outside of the dissection room through the intake pipe. Therefore, to surround the autopsy specimen,
A flow of air is drawn into the openings from top to bottom, forming a so-called air curtain.

Since washing water flows out from a large number of shower nozzles provided on the upper surface of the dissection table toward the center of the dissection table, blood is always washed away by the cleaning water and also flows out from the drain port along the bottom surface of the sink. Has become. And
In addition, blood, body fluids, filth, and the like generated from the autopsy specimen fall from the cage, but are blocked by the intake pipe cover arranged above the intake pipe, and are prevented from entering the inside through the intake pipe opening. Furthermore, since the upper edge opening of the inspiratory tube is covered with a net, even if tweezers, a scalpel or the like is dropped during dissection, it will not enter the inspiratory tube. Then, blood, body fluids, filth, etc. generated from the autopsied sample fall from the cage, flow toward the drain along the bottom of the sink, and flush water is flushed to wash them away, but the upper edge of the intake pipe is the sink. Since it projects above the bottom surface, blood, body fluid, dirt, etc., and wash water do not flow from the upper edge of the intake pipe.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An anatomy facility which is one embodiment of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a plan view of an anatomical table of an anatomical facility according to an embodiment of the present invention, and FIG. 2 is a plan view of an anatomical table of an anatomical facility according to an embodiment of the present invention with a cage 3 removed. is there. The dissection table is L-shaped, and has a main table 10 and a side table 11 for placing an autopsy specimen, and a shower nozzle 4 is arranged around the main table 10 and the side table 11. The upper surfaces of the main table 10 and the side table 11 are formed by the removable cage 3. An opening 301 is provided at a position slightly inside the periphery of the cage 3. Opening 30
FIG. 3 shows an enlarged cross-sectional view of No. The opening 301 of the cage 3 is concave so that the mesh 302 can be fitted therein, and the mesh 302 is fixed to the cage 3 by the pressing frame 303 from above. Since the cage 3 is made of a stainless steel plate, it has strength and is easy to wash and disinfect and is hygienic. Further, since the cage 3 has an upward convex arch shape, when the autopsy specimen 30 is incised, the incision is naturally opened, and anatomy and findings are easy to perform (see FIG. 5). Further, since the peripheral upper surface 9 of the dissecting table is inclined so as to be lowered toward the inner side, blood, body fluid, dirt and the like and washing water generated due to the dissection are disposed on the peripheral upper surface 9 of the dissecting table.
Even if it scatters, it will naturally flow down to the sink of the dissection table.
The connection between the main table 10 and the side table 11 is a sink 12, and the faucet 121 and the drain 1
22 and 22. Although hot water flows out from the faucet 121, its temperature and flow rate can be adjusted.

FIG. 5 is an explanatory view showing a use situation of the anatomical facility according to the embodiment of the present invention, including a sectional view of the anatomical facility according to the embodiment of the present invention.

The dissection table of the dissection facility of this embodiment is divided into an dissection table upper portion 1 and a dissection table lower portion 2. Lower part of dissection table 2
Is installed on the dissection room floor 24 so that the exhaust pipe 25 provided in the dissection room floor 24 is aligned with the intake pipe 6 of the dissection table.

A part of the intake pipe 6 includes a bellows pipe portion 601 which is vertically expandable and contractible while maintaining airtightness. Although not shown, the dissection table of the dissection facility of the present embodiment is provided with a mechanism for adjusting the height of the dissection table, and the dissection table upper part 1 can be moved up and down. Combined with these, there is an effect that the height of the dissection table can be freely adjusted while maintaining the airtightness of the intake pipe 6, and the height can be adjusted so that dissection can be easily performed according to the height and the like of the autopsy subject 31.

A sink is provided on the upper part 1 of the dissection table. The sink has a concave portion opened upward, on which the cage 3 is detachably and movably mounted. The cage 3 is an upwardly convex arch-shaped stainless steel plate having an opening 301 at a position slightly inside the periphery. As shown in FIGS. 3 and 4, a net 302 made of plastics is fitted into the opening 301 of the cage 3 and fixed by the pressing frame 303. By preparing several kinds of nets 302 made of plastics having different mesh roughness, and substantially controlling the opening area of the opening 301 of the cage 3 to control the intake amount and the intake speed from the opening 301. It is convenient because the dissection is easy and the wind noise can be reduced. In addition, when dirt or the like is caught on the plastic net 302 and clogging occurs during dissection, the opening 301 of the cage 3 and the plastic net 302 can be quickly replaced with a new plastic net 302. The structure of the holding frame 303 is designed. The net 302 is made of plastics because it is easy to clean the used net and disinfect it with chemicals or heat.
In addition, the fact that the deterioration of the net after cleaning and disinfection is unlikely to occur is taken into consideration. An autopsy specimen 30 is placed in the center of the cage 3. Therefore, the air is sucked toward the opening 301 of the cage 3, and the air curtain is formed so as to surround the subject 30 to be examined. When the opening of the air supply pipe 21 is arranged above the dissection room ceiling 20 corresponding to the opening 301 provided in the cage 3 of the dissection table, an air curtain is continuously provided between the dissection room ceiling 20 and the dissection table. It can be formed, and it is preferable that the autopsy subject 31 and the autopsy subject 30 can be sufficiently blocked by a continuous air curtain.

The upper edge of the intake pipe 6 is arranged so as to project above the sink bottom surface 7. In addition, as shown in FIGS. 2 and 5, the intake pipe cover 5 is arranged above the intake pipe 6 so as to be spaced apart from each other,
The opening of the intake pipe 6 is configured to be covered from above. In the present embodiment, the upper portion of the intake pipe cover 5 is flat, but in order to prevent blood and the like from depositing on the upper portion of the intake pipe cover 5, it is desirable to provide an inclination that decreases from the center toward the periphery. . By the way, blood, body fluid,
The dirt and the like passes through between the cage 3 and the cage 3 and falls, but since the opening of the intake pipe 6 is covered from above by the intake pipe cover 5, blood, body fluid, dirt, etc. may be mixed into the intake pipe 6. Absent. After dropping, blood, bodily fluids, dirt, etc. flow toward the drainage port 8 along the sink bottom surface 7, but since the upper edge of the intake pipe 6 is arranged so as to project above the sink bottom surface 7, Body fluid, dirt, etc. and washing water do not flow into the intake pipe 6. Further, since the net 602 having a coarse mesh is attached to the opening at the upper edge of the intake pipe 6, tweezers, a scalpel, etc. do not enter the intake pipe.

A laminar flow air supply pipe 21 is embedded in the ceiling 20 of the dissection room, and an opening of the laminar flow air supply pipe 21 is arranged at a position above the opening 301 of the cage 3 of the dissection table. An illuminator 22 such as a surgical light is provided directly above the dissection table. A transparent air hood 23 extends down from the dissection room ceiling 20 surrounding the opening of the laminar air supply tube 21.
Therefore, not only the dissection table but also the entire dissection room does not have a bright shadow, and dissection is easy.

An exhaust pipe 25 is embedded in the dissection room floor 24, and a fan is attached in the middle of the exhaust pipe 25 (not shown). A branch valve is attached to the exhaust pipe 25 at the downstream portion of the fan. By switching the branch valve, it is possible to change the discharge to either the outside or the inside of the dissection chamber. Further, when the fan is operated, intake air from the intake pipe 6 is increased. When fumigating the dissection chamber with formalin, etc., operate the fan and switch the branch valve. Then, the formalin gas is forcibly absorbed from the opening of the intake pipe 6 and introduced into the exhaust pipe 25, and the interior of the exhaust pipe is fumigated with the formalin gas. In addition, in order not to change the external environment more than necessary, it is considered that the formalin gas used for fumigation and disinfection in the exhaust pipe is not released to the outside but is circulated into the dissection room.

[0018]

EFFECTS OF THE INVENTION Air is sucked toward an opening provided at a position slightly inward from the periphery of the cage of the dissecting table of the dissecting apparatus according to the present invention to form an air curtain. Then, an autopsy specimen that may be infected with an infectious disease is placed in the center of the cage, and an autopsy person such as an anatomist works near the dissection table. Therefore, the air curtain is placed so as to surround the autopsy specimen, and this air curtain is always present between the autopsy specimen and the autopsy subject, so that the air infection caused by the aerosol generated from the autopsy specimen is effectively performed. Can be prevented.

Further, in the present invention, since the intake pipe cover is arranged apart from the upper part of the intake pipe, the body fluid, blood, etc. dripping from the subject is not mixed into the intake pipe.
Can inhale from the intake pipe. Therefore, the inside of the intake pipe can be kept clean.

Further, in the present invention, since the upper edge of the intake pipe projects above the bottom surface of the sink of the dissecting table, even if body fluid, blood, etc., or washing water flows along the bottom surface of the sink, they are Does not flow into the intake pipe. Therefore, water can be ejected from the surrounding shower nozzle even during dissection, the body fluid, blood and the like can be washed and removed with water, and the dissection table can be kept clean even during dissection.

Therefore, it is possible to simultaneously clean and remove body fluid, blood and the like and prevent air infection, and complete prevention of infection can be achieved.

In particular, according to the present invention, since the net is inserted into the opening of the cage, even if blood, body fluid, filth or the like gets stuck in the net during the dissection, the net can be quickly replaced. , It is possible to completely prevent infection without stopping dissection for a long time. In addition, cleaning and disinfection around the opening after dissection can be performed easily and completely.

In addition, according to the present invention, since the exhaust pipe of the dissection table is provided with the fan, formalin gas is forcibly introduced into the exhaust pipe for fumigation and disinfection can be completely prevented. .
