Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a special function work room that alternately performs pathological anatomy of a patient who died due to pathogen infection and organ removal from a corpse for organ transplantation. It is intended to obtain a special function working room that can prevent contamination of bacteria.
[0002]
[Prior art]
When pathologically dissecting a patient who died by infection with a pathogen, it is important to prevent the dissector from being infected with the pathogen and to prevent the pathogen from being scattered around. The conventional dissection table is merely a stainless steel plate-like body that simply considers a dead body, and is generally not provided with a pathogen infection prevention structure.
[0003]
In order to remedy the above-mentioned problems, the dissecting table of Utility Model Registration No. 1957866 (hereinafter referred to as the prior device) sucks a fresh downward air flow surrounding the body, that is, a laminar flow, below the dissecting table. Protects against pathogens and prevents the pathogens from scattering.
[0004]
FIG. 2 shows an outline of the prior art dissection table. A vertically long box-shaped main body case 3 that accommodates a cocoon-like plate-like body 1 on which a body is placed and a sterilizing solution tank 2 therebelow is provided with an opening 5 through which an anatomist 4 can put the upper body. A high-performance filter (hereinafter referred to as “hepa filter”) 6 and a blower 7 that can remove fine bacteria are provided on the upper portion of the main body case 3, and clean air is directed toward the plate-like body 1 in the main body case 3 . Blow down as a flow. The lower part of the main body case 3 communicates with a duct 9 provided with a blower 8 to sterilize and suck the air sucked from the slits 10 around the plate-like body 1 through the hepa filter 11. The sucked air is further detoxified through the hepa filter 12 and discharged to the outside by the blower 13. Part of the air that has passed through the duct 9 is guided to the upper part of the main body case 3 by the branch duct 14. A hepa filter 16 and a blower 17 are provided on the upper part of the dissection room 15 provided with the main body case 3 to sterilize the outside air and feed it to the dissection room 15. Blood, tissue debris, and the like produced at the time of dissection are sterilized by falling into the sterilizing liquid tank 2 from the claw-like gaps of the plate-like body 1 or falling into the sterilizing liquid tank 18 from the slit 10. Reference numeral 19 denotes an air conditioner.
[0005]
Because of the airflow generated by each of the blowers 7, 8, 13, and 17 described above, the air in the dissection room 15 is sucked into the main body case 3 from the opening 5, so that pathogens that emerge from the corpse are scattered in the dissection room. In addition, the surgeon 4 who dissects the upper body in the main body case 3 has no danger of inhaling the pathogen, and the pathogen is not discharged out of the dissection room 15 and can be safely dissected.
[0006]
In addition, it is necessary to protect the dissector from pathogen infection at the time of anatomy of a patient who died due to pathogen infection as described above, and the corpse for organ transplantation using this dissection room 15 and plate 1. When removing an organ from a mouse, it is desirable to perform it in a sterile environment. In other words, if transplantation is performed with various germs in the open air attached to the organ and contaminated, there is a high risk of causing a lesion after the transplantation and causing the transplantation to end unsuccessfully. No appropriate measures have been shown for organ removal in an aseptic environment.
[0007]
[Problems to be solved by the invention]
An object of the present invention is to obtain a special function working room that can safely perform pathological dissection without risk of infection with a pathogen and can perform organ removal for transplantation in aseptic conditions.
[0008]
[Means for Solving the Problems]
The present invention is provided with the above-described anatomical table, and is provided with a special function provided with an indoor air pressure switching device capable of switching the room to a negative pressure or a positive pressure depending on the dissection of the dead due to the pathogen and the dissection for organ removal. A work room is obtained to solve the above problems.
[0009]
[Action]
When performing pathological anatomy of a dead person due to a pathogen, the dissecting table of the present invention can protect the anatomist from the pathogen and prevent the pathogen from scattering into the working chamber. In addition, since the working chamber is set to a negative pressure, even if a pathogen leaks into the working chamber , there is no risk that it will go out of the room, and the safety of the outdoor can be ensured.
[0010]
For organ removal, use a positive pressure in the room. Therefore, there is no risk that germs and the like enter the work chamber from the outside, and the organ is not contaminated with germs.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a longitudinal side view schematically showing the configuration of a special function working chamber with adjustable indoor pressure according to the present invention.
[0012]
A front chamber 21 where an anatologist, an assistant, and the like prepare clothes is attached, and a laminar flow of clean air through a hepa filter 6 is passed through a hepa filter 6 in an airtight work chamber 22. A laminar flow blower 23a and a dissecting table 23b, which are previously conceived to blow down toward 1, are provided. From the air supply device 24 comprising a hepa filter and a blower, clean outside air enters the air conditioning device 19 through the air supply duct 26, and fresh air whose temperature, humidity, etc. are adjusted is supplied to the work room 22 through the duct 27. The A pressure adjusting damper 29 is provided on the partition wall 28 between the front chamber 21 and the working chamber 22, and a pressure adjusting damper 30 is provided on the outer wall of the front chamber 21. The front chamber 21 and the work chamber 22 are provided with hepa filters 33 and 34 for supplying clean outside air into the respective chambers by opening and closing motor dampers 31 and 32 communicating with the air supply duct 26 , respectively. The inside of the anterior chamber 21 passes through the duct 35, and the inside of the work chamber 22 passes through the slit 10 and the duct 9 of the dissecting table 23b and communicates with the exhaust device 25 including a hepa filter and a blower. Reference numeral 36 denotes an indoor air pressure switching device that controls the air supply device 24, the exhaust device 25, the motor dampers 31, 32, and the like to switch the indoor air pressure to Yin and Yang.
[0013]
Since it is configured as described above, the indoor air pressure switching device 36 controls the air supply by the air supply device 24 and the exhaust device 25, the exhaust air or the air supply by the motor dampers 31 and 32, so that the work chamber 22 and the front chamber 21 are controlled. Can be switched to negative or positive pressure. The degree of negative pressure in this case is about -3 to -5 mmaq in the working chamber and about -1 to -3 mmaq in the front chamber.
[0014]
When autopsy patients infected died pathogens, previously devised a laminar flow fan 23a, but it is possible to secure the dissection surgeon by dissecting table 23b, even when the still even airtight working chamber 22 is degraded In order to prevent pathogens from leaking out of the work chamber 22, the exhaust amount by the exhaust device 25 is increased, and the air supply amount by the air supply device 24 and the motor damper 32 is decreased to create a negative pressure in the work chamber 22 . As a result, the inside of the work chamber 22 has a lower pressure than the outside air, and even if the airtightness of the work chamber 22 is deteriorated, the pathogen can be prevented from leaking out of the work chamber 22 .
[0015]
At this time, the motor damper 31 supplying air to the front chamber 21 is stopped, and the flow of outside air into the front chamber 21 through the hepa filter 33 is stopped.
[0016]
Next, in the case of organ excision, if the airtightness of the dissection room is deteriorated, germs may invade from the outside and contaminate the removed organ. For this purpose, the pressure in the working chamber 22 and the front chamber 21 is made higher than that in the outside air by increasing the amount of air supplied by the air supply device 24 and decreasing the amount of exhaust by the exhaust device 25. The degree of increasing the pressure is about 3 to 5 mmaq in the working chamber and about 1 to 3 mmaq in the front chamber. The surplus positive pressure is discharged to the outside by the pressure adjusting dampers 29 and 30.
[0017]
【The invention's effect】
The work room is configured as described above, and the internal pressure of the work room is switched between negative pressure and positive pressure depending on the nature of the work. Therefore, at the time of pathological dissection, the anatomist is protected from infectious pathogens and the pathogen leaks out of the work room. In addition, it is possible to prevent the bacteria from adhering to and contaminating the removed organ during organ removal, and perform safe dissection and organ removal.
