The present invention is equipped with a large-capacity waste fluid collection container, and continuously and smoothly collects blood, body fluids, washing fluids, and perfusion fluids (hereinafter referred to as waste fluids containing blood and other body fluids) generated in medical settings. In addition to ensuring reliable and smooth medical practice, it also manages collected waste fluids safely and reliably, prevents overflow and leakage of waste fluids, prevents contamination, and ensures hygiene in medical sites and hospitals. , soak the waste liquid collected in a waste liquid collection container, wash it, decompose the protein in the waste liquid with a disinfectant detergent, dispose of the waste liquid after washing, wash the waste collection container with clean tap water, and remove the waste liquid from the waste liquid collection container. The present invention relates to a waste liquid treatment device, a waste liquid treatment method, and a cleaning method for a waste liquid treatment device, which enable rational and precise cleaning of waste liquid treatment devices.

As a device for processing body fluids such as nasal secretions and sputum collected from patients in hospitals, etc., body fluids are collected into multiple small-capacity cylindrical storage containers with lids attached, and these storage containers are installed at fixed locations in hospitals. Insert the nozzle into the through hole in the lid, attach the connector to the top of the nozzle, connect one end of the Y tube to the connector, and insert the other end of the Y tube into the housing. If the waste liquid in the storage container is to be discharged into the drain tank by connecting it to the installed drainage tank, drive the suction pump to suck out the air in the empty waste liquid tank, and then drain the waste liquid in the storage container using the nozzle. After suctioning and discharging the liquid into a wastewater tank, the cleaning liquid is introduced into the empty storage container, the wastewater tank is connected to atmospheric pressure, and the wastewater in the wastewater tank flows down to the waste stream and drains into the sewer. I try to discharge it.

Next, air is taken in from the air intake pipe, guided into the Y tube, and blown out into the cleaning solution inside the storage container for bubbling cleaning. At that time, if the storage container is heavily soiled, tap water is poured around the outside of the storage container. There is a method in which the outside is blown away and heated air is blown onto the outside to dry it (see, for example, Patent Document 1).

However, this waste liquid treatment device is cumbersome as it requires the production of multiple storage containers, the collection of waste liquid into them, and the loading and unloading of waste liquid into and out of the housing. There is a problem in that cleaning requires various equipment and a long time.
Furthermore, when cleaning the storage container, the waste liquid is disposed of and then sprayed with a cleaning liquid such as tap water, so there is a limit to the accuracy of cleaning waste liquid containing proteins; There were problems such as breakdowns and pollution of sewage equipment.

In addition, as another waste liquid treatment device, a large-capacity (15L) sealed tank is housed in a box-shaped casing, and the tank has a body fluid introduction port for receiving body fluids generated at medical sites, and a body fluid discharge port for discharging body fluids. The first and second pressure tanks that introduce compressed gas from the outside are placed directly above the sealed tank, and these pressure tanks and the sealed tank are connected with a compressed gas supply pipe, and the compressed gas supply pipe is It is equipped with an opening/closing mechanism that opens and closes, and when the compressed gas supply pipe is set to the open state by this opening/closing mechanism, compressed gas is supplied from the pressure tank to the closed tank via the compressed gas supply pipe, and the waste liquid in the closed tank is There is one in which the surface is pressurized to discharge waste liquid from a discharge port (for example, see Patent Document 2).

However, since this waste liquid treatment device houses a closed tank and two pressure tanks in the casing, the casing or waste liquid treatment device becomes large, and the pressure tank must be manufactured. The piping between compressed gas supply pipes, branch pipes, and valves placed on them becomes complicated, which complicates the equipment structure, and because the capacity of the sealed tank is not very large, the frequency of draining waste liquid increases, making work cumbersome. In addition to being inefficient, since medical gas is used to discharge the waste liquid, there are problems such as an increase in consumption of medical gas and an increase in running costs.
Furthermore, since the waste liquid is sprayed with a cleaning liquid such as tap water after being disposed of, there is a limit to the accuracy of cleaning waste liquid containing proteins, and disposal of waste liquid containing proteins can cause malfunctions and contamination of sewage equipment. There were problems with inviting people.

A waste liquid treatment device that solves such problems is equipped with a first sealed container and a second sealed container capable of storing waste liquid, the capacity of the second sealed container is configured to be five times or more that of the first sealed container, and the first sealed container is The waste liquid is stored in a first sealed container, and the waste liquid in the first sealed container is transferred to a second sealed container.The first sealed container has a first liquid suction port, a first liquid discharge port, and a first liquid discharge port. A gas exhaust port and a first cleaning port are provided, the outlet side of the liquid suction pipe is connected to the first liquid suction port, the inlet side of the container connecting pipe is connected to the first liquid exhaust port, and the first gas exhaust port is connected to the outlet side of the liquid suction pipe. The inlet side of the first gas suction pipe among the gas suction pipes is connected to the gas suction pipe, and the outlet side of the first cleaning pipe is connected to the first cleaning port.

The second closed container is provided with a second liquid suction port, a second gas discharge port, a second cleaning port, and a gas communication port, and the outlet side of the container connection pipe is connected to the second liquid suction port, and The inlet side of the second gas suction pipe is connected to the second gas exhaust port, the outlet side of the second cleaning pipe is connected to the second cleaning port, and the communication pipe is connected to the gas communication port. There is.

The waste liquid treatment device includes a gas suction passage for sucking gas from the first sealed container and the second sealed container, and sucks the gas from the first sealed container and the second sealed container via the gas suction passage, Negative pressure can be formed in the first and second sealed containers, and while drawing waste liquid into the first sealed container from the outside, a pressure difference is generated between the first sealed container and the second sealed container, and a first liquid discharge port is created. There is a device in which waste liquid is transferred from a first sealed container to a second sealed container through a second liquid suction port (for example, see Patent Document 3).

However, in this waste liquid treatment device, one of the two sealed containers must have a large capacity, and the waste liquid is transferred from the first sealed container to the second sealed container due to the differential pressure between the two sealed containers. Since the waste liquid is transferred, it is difficult to ensure stable differential pressure formation and stability in the amount of waste liquid transferred, which poses a problem in that it is difficult to ensure smooth and stable medical practice.

In addition, when cleaning the first and second sealed containers with the waste liquid treatment device, there is a step of supplying cleaning water to these sealed containers to clean each, and a step of supplying cleaning water to these sealed containers, and supplying gas from the second sealed container through the gas suction passage. Since the sewage in the first closed container is suctioned and transferred to the second closed container through the first liquid discharge port and the second liquid discharge port, after washing each closed container, the first This method requires a process of transferring the waste water in the closed container to the second closed container, which is time-consuming and has problems such as a lack of precision in cleaning.
Moreover, since the waste liquid is washed by spraying tap water through a sprinkler after it is disposed of, there is a limit to the accuracy of cleaning waste liquid containing proteins, and furthermore, disposal of waste liquid containing proteins can cause malfunction and contamination of sewage equipment. There were problems with inviting people.

Another waste liquid treatment device that solves this problem is to arrange a suction chamber and a drainage chamber above and below within the device body, and configure them so that they can be connected to each other by an electromagnetic on-off valve, and an outlet box is placed outside the room. The apparatus is configured so that waste liquid other than the main body of the apparatus can be discharged to the outside, and the suction chamber is configured to generate negative pressure via a vacuum pump. A suction hose is connected to the suction chamber, and a funnel-shaped concentration pad is attached to the tip of the suction hose. The drain chamber is pressurized via a compressor, and the sewage inside the room can be discharged to the drain side.

Body fluids such as blood generated during surgery are sucked into a concentrated pad, guided through a suction hose and moved to a suction chamber, the amount of suction is detected by a liquid level sensor, and when the required amount is detected, a vacuum pump is activated. At the same time, the electromagnetic on-off valve is opened to allow the sewage to fall into the drainage chamber, and when the amount of sewage decreases, the vacuum pump is restarted and suction begins.
On the other hand, the sewage that has flowed into the drainage chamber is moved from the drainage chamber to the drainage tank of the outlet box via the indoor drainage pipe by the air pressurized by the compressor that is started during operation, and is disposed of outside. There is a device that cleans and disinfects an apparatus including an outlet box by flowing a cleaning solution and a disinfectant solution from a suction chamber to an external drain pipe (for example, see Patent Document 4).

However, in this waste liquid treatment device, the suction chamber and the drainage chamber are placed one above the other in the device body, which makes the device large and heavy, and it is not possible to provide a large capacity for the suction chamber and the drainage chamber, which reduces the amount of body fluid suctioned. The amount of discharge from the drainage chamber is restricted, making it difficult to collect waste liquid continuously and smoothly, making it difficult to perform medical procedures reliably and smoothly in medical settings.In addition, if the device falls during movement, the suction chamber and drainage will be damaged. There is a risk that the waste liquid inside the room may leak and cause contamination or contamination, and when cleaning the suction chamber or drainage chamber, the cleaning liquid and disinfectant liquid are simply allowed to flow down, so cleaning waste liquid containing proteins lacks precision. There was a problem.

In the figure, reference numeral 19 denotes a pressure regulator disposed between the suction filters 9 and 10, and its pressure conduit communicates with a waste liquid collection container to be described later, making it possible to measure and adjust the pressure in the waste liquid collection container.

A cylindrical support tube 20 is attached to the bottom of the device main body 2 facing upward, and the lower part of a bottomed cylindrical waste liquid recovery container 21 is fitted into the support tube 20 and accommodated, and the periphery of the fitting portion is It is fixed by welding.
The waste liquid recovery container 21 is composed of a bowl-shaped bottom part 21a made of a press-formed stainless steel plate, and a long body part 21b made of a stainless steel plate formed into a cylindrical shape.The joints of these parts are welded to form a bottomed cylindrical shape. It has a large capacity of 60 to 70 L, in the embodiment 72 L, and a disc-shaped lid 22 is placed on the flange 21c of the upper opening of the body 21b.

A seal packing (not shown) is interposed between the flange 21c and the lid body 22, a plurality of bolts (not shown) are arranged at this overlapping part, and a nut (not shown) is screwed into the screw shaft protruding from the top. The opening is liquid-tightly sealed.
Therefore, even if the apparatus main body 2 falls during movement or surgery, the waste liquid collection container 21 can prevent the internal waste liquid from leaking to the outside or staining and contaminating the surrounding area. In the figure, 23 is a gap provided between the inside of the apparatus main body 2 and the waste liquid recovery container 21.

A waste liquid overflow prevention device 24 is attached to the outer periphery of the upper end of the waste liquid collection container 21 to prevent the waste liquid from overflowing or backflowing when the waste liquid 25 in the waste liquid collection container 21 is collected.
The waste liquid overflow prevention device 24 is vertically supported via a clip holder 28 on a tributary pipe 27 of a suction hose 26 which is connected to a hospital suction equipment piped inside the main body head 6 .

In the waste liquid overflow prevention device 24, a partition plate 30 is fixed to the upper end of a tubular outer cylinder 29, and a tributary pipe 27 is opened in a through hole in the center of the partition plate 30. A stepped packing guide 31 is arranged inside the partition plate 30, and a thick packing 32 is arranged in the upper part of the packing guide 31. A through hole 33 is formed in the center of the packing 32, and a through hole 33 is formed in the center of the packing 32. A flexible hollow cone seal 34 in the shape of a truncated cone is provided at the lower opening of the hole 33 so that it can be crushed and restored to its original shape, and normally maintains its original truncated cone shape to allow ventilation, but when crushed, it forms a plate-shaped cone seal 34. The through hole 33 can be closed by being crushed.

A disk plate 35 is disposed directly below the cone seal 34 so as to be movable up and down, and a float 37 is fixed to the lower end of a support shaft 36 of the disk plate 35 . The float 37 is shaped like a bell, and is movable with the liquid level due to the buoyancy of the waste liquid 25 in the waste liquid collection container 21.
In the waste liquid overflow prevention device 24, when the liquid level of the waste liquid 25 is located below the float 37, the disk plate 35 is placed at the lowest position, and the negative pressure air in the waste liquid collection container 21 flows into the packing guide 31. is guided to the tributary pipe 27 through the through hole 33 and discharged to the outside, making it possible for the operation hose 27 to suction and recover the waste liquid 25. This situation is as shown in FIG. 7(a).

On the other hand, when the amount of recovered waste liquid 25 increases and the liquid level rises and comes into contact with the lower part of the float 37, the float 37 is pushed up by the buoyancy of the waste liquid 25, and the disc plate 35 moves with it. The cone seal 34 is crushed into a plate shape to close the through hole 33.
As a result, the movement of the negative pressure air through the through hole 33 is blocked, and the upper part of the float 37 comes into contact with the lower end of the packing guide 31, preventing the upward movement of the negative pressure air through the through hole 33. The waste liquid 25 that has entered the packing guide 31 is prevented from moving, thereby preventing it from entering the tributary pipe 27 or flowing backward, that is, from overflowing into the hospital. This situation is as shown in FIG. 7(b).

At that time, the negative pressure inside the waste liquid collection container 21 decreases due to the air mixed in as the operation hose 17 and the sub-operation hose 18 collect the body fluid, and the body fluid collection ability decreases and the collection of body fluids etc. is stopped. This prevents overflow of body fluids, etc.

A cross-shaped outlet valve 38 is protruded from the bottom of the waste liquid recovery container 21, and one end of a connecting hose 39 is connected to one end of the outlet valve 38, and a liquid column pipe 40 is communicated with the tip thereof.
