In the separation device having the above configuration, body fluid and the like sucked from the patient are sucked together with air into the container through the suction side pipe. At this time, the bodily fluid is stored in the container, and the air sucked into the container together with the bodily fluid is exhausted through the exhaust pipe.

JP 2014-147436 A

In the above-described conventional separation device, there are cases in which the object to be sucked, such as body fluid, is discharged through the exhaust-side pipe together with the air.

SUMMARY OF THE INVENTION An object of the present invention is to provide a separation device capable of preventing an object to be sucked from being discharged to the downstream side together with air, and a suction device provided with this separation device.

One aspect of the present invention is
a first closed container;
a second sealed container containing a drug for disinfecting or sterilizing bacteria and viruses;
a first pipe that guides the object sucked together with the air to the first sealed container;
a second pipe that guides the air that has flowed into the first closed container to the outside of the first closed container;
a third pipe that guides the air that has flowed through the second pipe into the second sealed container;
and a guide part for guiding the air flowing into the second airtight container from the third pipe toward the inner peripheral surface of the second airtight container.

Here, the object to be sucked is a liquid other than air, a solid, or the like, such as vomit.

According to the above configuration, air flowing into the second airtight container from the third pipe is guided toward the inner peripheral surface of the second airtight container. As a result, even if the object to be sucked flows into the second sealed container together with the air, the air collides with the inner peripheral surface of the second closed container to separate the air and the object to be sucked. It is stored in the second airtight container. As a result, it is possible to prevent the object to be sucked from being discharged to the downstream side of the separation device together with the air.

In one embodiment of the separation device,
A passage area of the air guided by the guide portion is smaller than a passage area of the air guided by the third pipe.

According to the above embodiment, since the flow path area of the air guided by the guide portion is smaller than the flow path area of the air guided by the third pipe, the air flowing from the third pipe into the second sealed container is reduced. You can increase the flow speed. This makes it easier for the air to collide with the inner peripheral surface of the second airtight container, and makes it easier for the air and the object to be sucked to be separated. As a result, it is possible to prevent the object to be sucked from being discharged together with the air.

In one embodiment of the separation device, the third pipe guides air from the second pipe side to the second closed container side so that a swirl flow of air is generated in the second closed container.

According to the above embodiment, since the air swirls in the second closed container, the centrifugal force makes it easier to separate the air and the object to be sucked. As a result, it is possible to prevent the object to be sucked from being discharged together with the air.

The separation device of one embodiment comprises:
Provided with a connecting pipe that connects the second pipe and the third pipe,
The connecting pipe defines an air flow path extending in a direction intersecting the direction in which the third pipe extends,
The axis of the air flow channel is offset in the radial direction of the third pipe from the axis of the air flow channel defined by the third pipe.

The separation device of one embodiment comprises:
A fourth pipe that guides the air that has flowed into the second closed container to the outside of the second closed container,
A said 4th pipe is arrange|positioned in a said 4th pipe so that the outer peripheral surface of a said 4th pipe may oppose the inner peripheral surface of a said 3rd pipe.

The separation device of one embodiment comprises:
A drug container filled with the drug,
The drug in the drug container is sucked and mixed with the air flowing from the first closed container toward the second closed container.

According to the above embodiment, by mixing the drug from the drug container with the air flowing between the first closed container and the second closed container, bacteria contained in the aspirated material flowing into the second closed container together with the air and viruses can be disinfected or sterilized.

In addition, by mixing the drug from the drug container with the air flowing between the first closed container and the second closed container, the wettability of the aspirated substance flowing into the second closed container together with the air increases. This makes it easier for the object to be sucked to adhere to the inner peripheral surface of the second closed container, and makes it easier for the air and the object to be sucked to separate. As a result, it is possible to prevent the object to be sucked from being discharged to the downstream side together with the air.

The separation device of one embodiment comprises:
an intake/exhaust block having an intake port for sucking the object to be sucked together with air and an exhaust port for discharging the air from the intake port to the outside;
The intake/exhaust block is swingable with respect to the first sealed container and the second sealed container.

When a hose for sucking an object to be sucked is attached to the suction port, movement of the hose tilts the first closed container and the second closed container. There is a risk that substances may flow back into the suction port, or that the drug contained in the second closed container may flow into the exhaust port. On the other hand, according to the above-described embodiment, since the intake/exhaust block can swing with respect to the first closed container and the second closed container, even when the intake/exhaust block is tilted, the first closed container and the second closed container 2, it is possible to suppress the inclination of the sealed container.

The separation device of one embodiment comprises a deodorant arranged downstream of the outlet.

According to the above embodiment, the deodorant can reduce the odor of the air discharged from the exhaust port.

The suction device of one aspect of the present invention includes
a suction device main body;
and a separation device according to any one of claims 1 to 8,
The suction device main body is arranged downstream of the separation device.

According to the above configuration, since the suction device main body is arranged on the downstream side of the separation device, it is possible to prevent the object to be suctioned from moving toward the suction device main body. Therefore, it is possible to reduce the possibility that the suction device body will fail due to the suction of the object to be sucked.

In one embodiment of the suction device,
The suction device main body includes a first filter,
The separation device includes a second filter provided downstream of the second sealed container,
The second filter is finer than the first filter.

According to the above embodiment, the substance to be sucked that flows together with the exhaust air from the second airtight container can be captured by the second filter. Therefore, it is possible to reduce the possibility that the suction device body will fail due to the suction of the object to be sucked.

In addition, if the mesh of the second filter is coarser than that of the first filter, the first filter may be clogged with dust or the like contained in the exhaust gas from the second sealed container that could not be captured by the second filter. , a load may be applied to the main body of the suction device. On the other hand, since the mesh of the second filter is finer than that of the first filter, clean air is supplied to the main body of the suction device. Therefore, clogging of the first filter with dust or the like contained in the exhaust air from the second airtight container can be suppressed, and the load on the main body of the suction device can be reduced.

As a result, even if the vomit 100 flows into the second container 50 together with the air, the air collides with the inner peripheral surface of the second container 50 to separate the air and the vomit 100. It is captured in the second container 50. As a result, discharge of vomit 100 to the downstream side together with air can be suppressed.

Since the air passage area at the outlet of the space between the inner peripheral surface of the third pipe 60 and the outer peripheral surface of the fourth pipe 70 is smaller than the air passage area in the third pipe 60, the space The flow velocity of the air flowing into the second container 50 from the outlet can be increased. This makes it easier for the air to collide with the inner peripheral surface of the second container 50 , and makes it easier for the air and the vomit 100 to separate in the second container 50 . As a result, discharge of vomit 100 to the downstream side together with air can be suppressed.

Since the air flows while swirling in the second container 50, the air and the vomit 100 are easily separated by centrifugal force. As a result, it is possible to prevent the vomit 100 from being discharged from the second container 50 together with the air.

By mixing the drug from the drug container 5 with the air flowing between the first container 20 and the second container 50, bacteria and viruses contained in the vomit 100 flowing into the second container 50 together with the air are sterilized or removed. Can be sterilized. As a result, the sanitary condition of the exhaust air from the second container 50 can be maintained well.

Further, by mixing the medicine from the medicine container 5 with the air flowing between the first container 20 and the second container 50, the wettability of the vomit 100 discharged together with the air into the second container 50 is enhanced. This makes it easier for the vomit 100 to adhere to the inner peripheral surface of the second container 50, and makes it easier for the air and the vomit 100 to separate. As a result, it is possible to prevent the vomit 100 from being discharged from the second container 50 together with the air.

When the extension hose 4 for sucking the vomit 100 is attached to the suction port 2a, movement of the extension hose 4 tilts the first container 20 and the second container 50. There is a risk that the discharged vomit 100 may flow back into the suction port 2a, or the medicine contained in the second container 50 may flow into the exhaust port 2b. On the other hand, since the intake/exhaust block 90 can swing with respect to the first container 20 and the second container 50, even if the intake/exhaust block 90 is tilted due to the movement of the extension hose 4 or the like, the first container 20 can still move. and the second container 50 can be suppressed from tilting.

Since the deodorant 96 is arranged on the downstream side of the exhaust port 2b, the odor of the air discharged from the exhaust port 2b can be reduced by the deodorant.

Since the suction device main body 1 is arranged on the downstream side of the separation device 2, the vomit 100 can be prevented from going toward the suction device main body 1. - 特許庁Therefore, it is possible to reduce the possibility that the suction device main body 1 will fail due to the suction of the vomit 100 .

Since the filter 97 is provided on the downstream side of the exhaust port 2b, even if the vomit 100 is discharged from the second container 50 together with the air, the vomit 100 can be caught by the filter 97. Therefore, it is possible to reduce the possibility that the suction device main body 1 will fail due to the suction of the vomit 100 .

If the mesh of the filter 97 is coarser than that of the filter 16 for dust collection provided in the suction device main body 1, the filter 16 will be clogged with dust that cannot be captured by the filter 97, and the suction device main body 1 will be blocked. A load may be applied to the motor 14 of . On the other hand, in this embodiment, since the mesh of the filter 97 is finer than the mesh of the filter 16 for dust collection provided in the suction device main body 1, clean air is sucked into the suction device main body 1. . Therefore, clogging of the filter 16 by dust contained in the air discharged from the separation device 2 is suppressed, and the load on the motor 14 of the suction device main body 1 can be reduced.

In the above embodiment, a further filter may be provided upstream or downstream of the filter 97 . If the filter is provided upstream of the filter 97, the filter may have a coarser mesh than the filter 97. If the filter is provided downstream of the filter 97, the filter may be finer than the filter 97.

In the above-described embodiment, the suction device main body 1 is of the cordless type, but may be of the non-cordless type.

In the above embodiment, the suction nozzle 3 may have a function of injecting a liquid such as water or a disinfectant toward the vomit 100 . In this case, when the vomit 100 is being dried, the vomit 100 is softened with moisture such as water, and the vomit 100 can be easily sucked.
