Description

Storage container and storage module

The present invention relates to a storage container and a storage module.

Conventionally, various storage containers for biological drainage have been proposed (see, for example, Patent Document 1). Such a storage container is used for purposes such as storage of biological drainage discharged by human power such as urine and storage of biological drainage naturally discharged by a urinary catheter or the like.

JP2013-169414A

By the way, when it cannot be discharged by human power or cannot be discharged naturally, such as a liquid stored by a cuff inserted into the pharynx, it is discharged using a suction source such as a suction pump. When the suction source is connected to the storage container as described above, the storage container is deflated by the suction force of the suction source, making it difficult to continue the suction of the liquid.

The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a storage container and a storage module that can continue the suction of biological drainage using a suction source.

A storage container that solves the above problems is flexible, and is housed in the container main body in which an inflow port through which liquid and gas flow and an exhaust port through which gas is exhausted are disposed, A water-absorbing structure that absorbs liquid flowing into the container body from the inlet, and the water-absorbing structure includes a water-absorbing member, and a plurality of the water-absorbing structures are arranged along the inner surface of the container body. A plurality of groove portions are formed by the container main body and the plurality of water absorption structures, and the plurality of groove portions form a plurality of flow paths through which the gas can pass through the inflow port and the exhaust port.

According to this configuration, for example, a suction source is connected to the exhaust port of the storage container, and the suction source sucks the liquid from the inflow port into the container body. A plurality of water-absorbing structures having a water-absorbing member housed in the container main body are juxtaposed along the inner surface of the container main body, and absorb the liquid in the container main body. A plurality of grooves formed by the container body and the plurality of water absorbing structures form a plurality of channels through which the gas can pass through the inflow port and the exhaust port. Since the gas inside the container body is sucked into the suction source, the inside of the container body becomes negative pressure, and the suction source is continuously sucked to suck liquid from the outside of the container body into the container body through the inlet. can do. Further, even if the flexible container body is bent by the suction of the suction source, the flow path can be secured by appropriately setting the size (width, depth) of the plurality of grooves. Moreover, the some water absorption structure arranged in parallel along the inner surface of a container main body forms one or more groove parts among them, and this groove part can form a flow path of gas. The degree of freedom of arrangement of the water absorption structure inside the container body is increased, and the water absorption structure can be arranged in a plurality of regions according to the usage form of the storage container. For example, a plurality of water-absorbing structures are arranged in different areas within the same plane, for example, in a regular or irregular plane pattern (tile, mosaic, etc.), without adjacent gaps or with gaps. Can be separated and placed. The first set of water-absorbing structures and the second set of water-absorbing structures can be placed one on top of the other, and two or more layers of water-absorbing structures can be placed inside the container body. The size and / or shape of the plurality of water absorbing structures can be appropriately set according to, for example, the usage form of the storage container and / or the shape of the container body. For example, the plurality of water absorbing structures may have the same shape, different shapes, the same size, or different sizes.

A plurality of grooves are formed by the container main body and the water absorption structure, and the plurality of grooves form a plurality of flow paths through which gas can pass through the inflow port and the exhaust port. To do.

According to this configuration, for example, a suction source is connected to the exhaust port of the storage container, and the suction source sucks the liquid from the inflow port into the container body. The water absorbing structure has a plurality of water absorbing members and is arranged along the inner surface of the container body to absorb the liquid in the container body. A plurality of grooves formed by the container main body and the water absorbing structure form a plurality of flow paths through which the gas can pass through the inflow port and the exhaust port, thereby allowing the container to pass through the plurality of flow paths. Since the gas in the main body is sucked into the suction source, the inside of the container body becomes a negative pressure, and the suction source is continuously sucked to suck liquid into the container body from the outside of the container body through the inlet. Can do. For example, a plurality of grooves can be formed by one water absorbing structure including a plurality of water absorbing members and the container body. And even if the flexible container main body is bent by the suction of the suction source, the flow path can be secured by appropriately setting the sizes (width, depth) of the plurality of grooves.

Also, a plurality of water absorbing structures arranged side by side along the inner surface of the container main body may form one or more grooves between them, and the grooves may form a gas flow path. A plurality of water-absorbing members included in one or each water-absorbing structure formed side by side along the inner surface of the container body form one or more grooves, and these grooves form a gas flow path. obtain.

The storage container preferably has three or more flow paths.
According to this structure, at least 1 or more flow path is comprised by the water absorption structure. For this reason, the contact area between the liquid that has flowed in from the outside of the container main body via the inlet and the water absorbing member can be increased, and more liquid can be sucked. Further, even when one channel is blocked by absorbing and expanding the liquid that has flowed in from the inlet, the other channel can keep the inlet and the exhaust port in communication. It becomes possible to continue sucking the liquid into the container body from the outside of the container body through the inlet.

Said storage container WHEREIN: It is preferable that the said some water absorption structure is attached to the inner surface of the said container main body, or the support plate accommodated in the said container main body.

In the above storage container, it is preferable that the inflow port is disposed in a lower portion of the container body and the exhaust port is disposed in an upper portion of the container body.
According to this configuration, the liquid flows in from the inlet disposed in the lower part of the container body, and the gas in the container body flows out from the exhaust port disposed in the upper part of the container body. For this reason, it is difficult for the liquid to reach the exhaust port, and it is difficult for the liquid to flow out of the exhaust port.

In the storage container, the container body is formed to have a pair of opposing sides, the inlet is disposed on one side of the pair of sides, and the exhaust port is the pair of sides. It is preferable to be disposed on the other side of the sides.

According to this configuration, a distance between the inflow port and the exhaust port can be secured. The liquid flowing in from the inflow port disposed on one side is absorbed by the water absorbing member of the water absorbing structure. For this reason, it is difficult for the liquid to reach the exhaust port, and it is difficult for the liquid to flow out of the exhaust port.

The sheet material having water permeability can lead the liquid in the container main body to the water absorbing member by capillary action, for example, and can contribute to maintaining the flow path in a gas flowable state. Moreover, since the water absorbing member is enclosed by the sheet material, the form of the water absorbing member that can be used as the water absorbing member increases. For example, non-blocking water absorbing members such as powder water absorbing members and granular water absorbing members can be used.

In the above storage container, the sheet material is preferably a nonwoven fabric.
According to this configuration, the nonwoven fabric has good water permeability, and the liquid flowing into the container body is well absorbed by the water absorbing member via the nonwoven fabric sheet material.

A suction module that solves the above problem includes the storage container, and a suction source that is connected to the storage container and sucks the gas in the storage container.
According to this structure, the inside of a storage container becomes a negative pressure with the suction source connected to the storage container, and a liquid is suck | inhaled in a container main body from an inflow port. The water absorbing structure accommodated in the container body includes a water absorbing member included in the sheet material. Two adjacent water absorbing members form a flow path that connects the inlet and the outlet between the container main body and the water absorbing structure. Since the gas in the container body is sucked into the suction source through this flow path, it is possible to continue sucking the suction source and suck the liquid into the container body from the outside of the container body through the inlet. can do.

Hereinafter, each embodiment will be described.
In the accompanying drawings, components may be shown in an enlarged manner for easy understanding. The dimensional ratios of the components may be different from the actual ones or in other drawings. Further, in the cross-sectional view, in order to facilitate understanding, hatching of some members may be shown in place of a satin pattern, and hatching of some members may be omitted.

(First embodiment)
First, an application example of the storage container of the present embodiment will be described.
As shown in FIG. 3A, the storage container 10 includes a container main body 11, a suction pipe 12 and a discharge pipe 13 connected to the container main body 11. The suction pipe 12 is connected to a cuffed tracheal tube 50, and the discharge pipe 13 is connected to a suction source 40.

The cuffed tracheal tube 50 has a tracheal tube 51 and a cuff 52. The cuff 52 is provided at a predetermined position on the outer periphery of the tracheal tube 51 at the distal end portion of the tracheal tube 51. In the wall of the tracheal tube 51, a flow path (not shown) communicating with the inside of the cuff 52 is formed. The cuff 52 is expanded by the air supplied through the flow path. A suction path 53 is formed in the wall portion of the tracheal tube 51. The suction path 53 communicates with the outside of the tracheal tube 51 through an opening 54 formed on the outer surface of the tracheal tube 51. The opening 54 is formed at a predetermined portion above the cuff 52. The suction path 53 is connected to the connection pipe 55. The suction pipe 12 of the storage container 10 is connected to the connection pipe 55.

As shown in FIG. 3B, the tracheal tube 51 is inserted into the trachea 92 from the oral cavity 90 of the subject. This ensures the airway by tracheal intubation when using the ventilator. At this time, since the epiglottis 93 is always opened, secretions such as saliva may flow into the trachea 92 from the gap between the inserted tracheal tube 51 and the inner wall 92a of the trachea 92. In addition, the code | symbol 94 shown to a figure is an esophagus.

In order to prevent such inflow of secretions, the cuff 52 provided in the tracheal tube 51 is inflated with air supplied. The expanded cuff 52 contacts the inner wall 92a of the trachea 92 and closes the gap between the tracheal tube 51 and the inner wall 92a of the trachea 92. By using such a cuffed tracheal tube 50, it is possible to prevent the inflow of secretions and the like from the trachea 92 to the lung by the cuff 52 while securing the airway by the tracheal tube 51.

Then, the suction source 40 shown in FIG. Then, secretions and the like stored in the upper part of the cuff 52 are sucked into the suction path 53 from the opening 54. The secretions or the like sucked into the suction passage 53 flows into the container main body 11 of the storage container 10 through the connection pipe 55 and the suction pipe 12, and is stored in the container main body 11 as a biological drainage.

Next, the storage container of this embodiment will be described.
As shown in FIG. 1A, the storage container 10 has a container body 11. The container body 11 is formed in, for example, a rectangular shape that is long in the vertical direction (also referred to as the gravity direction). In the present specification, the “rectangular shape” includes a rectangle with chamfered corners and a rectangle with rounded corners.

A hanging hole 14 as a hanging portion is formed in the upper end portion of the container body 11. The suspension hole 14 is used to suspend the storage container 10 on, for example, the side of a bed, an infusion rack, or a ventilator rack. In addition, although two hanging holes 14 are shown in FIG. 1A, one or three or more hanging holes may be provided. Further, one of the plurality of hanging holes may be used for hanging the storage container 10.

The container body 11 has flexibility. As a material for the flexible container body 11, for example, polyethylene, polypropylene, polyvinyl chloride, ethylene vinyl acetate polymer, or the like can be used.

As shown in FIG. 1C, the container body 11 has a pair of flexible sheet materials 15a and 15b. As shown in FIG. 1A, the flexible sheet materials 15a and 15b are joined to each other along the entire periphery. As a method of joining the flexible sheet materials 15a and 15b, heat fusion, adhesive, or the like can be used. In FIG. 1A, the front side of the paper surface is the flexible sheet material 15a, and the back side of the paper surface is the flexible sheet material 15b.

As shown in FIG. 1 (a), a suction pipe 12 and a discharge pipe 13 are attached to the container body 11. The suction pipe 12 and the discharge pipe 13 are formed in a cylindrical shape, for example.
An insertion port 16 is formed in the flexible sheet material 15a. The tip of the suction pipe 12 is inserted into the container body 11 from the insertion port 16. The suction pipe 12 is fixed to the container body 11 so that the inlet 12a at the tip of the suction pipe 12 is located in the lower part 11a of the container body 11. In the insertion port 16, the flexible sheet material 15 a is in close contact with the outer peripheral surface of the suction pipe 12 by, for example, thermocompression bonding or an adhesive.

As shown in FIG. 1 (a), an insertion port 17 is formed in the flexible sheet material 15a. The distal end of the discharge pipe 13 is inserted from the insertion port 17 into the container body 11. The discharge pipe 13 is fixed to the container main body 11 so that the exhaust port 13a at the tip thereof is located in the upper part 11b of the container main body 11. In the insertion port 17, the flexible sheet material 15 a is in close contact with the outer peripheral surface of the discharge pipe 13 by, for example, thermocompression bonding or an adhesive.

A filter 18 is attached inside the container body 11. The filter 18 is a hydrophobic filter, for example. The filter 18 is disposed inside the container body 11 so as to cover the exhaust port 13 a of the discharge pipe 13. With this filter 18, the liquid (biological drainage) does not reach the suction source 40 through the discharge pipe 13, so that the failure of the suction source 40 due to the liquid can be suppressed.

As shown in FIG. 1A, the container main body 11 houses a water absorbing structure 20. The water absorption structure 20 absorbs the biological drainage flowing into the container body 11.
As shown in FIG. 1C, the water absorbing structure 20 includes a sheet material 21 and a plurality of water absorbing members 27. The plurality of water absorbing members 27 are included in the sheet material 21. As shown in FIG. 1B, the sheet material 21 is formed in a rectangular shape. The plurality of water-absorbing members 27 are arranged in a distributed manner with respect to the entire water-absorbing structure 20 by the sheet material 21.

As the sheet material 21, for example, a fiber material such as a nonwoven fabric or low density pulp can be used. As the water absorbing member 27, a water absorbing polymer material (water absorbing polymer) or the like can be used.

In the present embodiment, the sheet material 21 is formed by joining a pair of sheets 22a and 22b. The sheet material 21 has a first joint portion 23 in which the peripheral portions of the pair of sheets 22a and 22b are joined to each other. And the sheet material 21 has the 2nd junction part 24 which mutually joined the sheet | seats 22a and 22b so that the inner side of the 1st junction part 23 may be divided into the some area | region 25. FIG. In FIG. 1B, the region 25 is indicated by a solid line and is satin-finished for easy understanding. As shown in FIG. 1C, the water absorbing member 27 is accommodated in a plurality of regions 25 partitioned by the first joint portion 23 and the second joint portion 24. In the example shown in FIGS. 1B and 1C, the plurality of water absorbing members 27 are arranged along the inner surface of the container main body 201.

In the present embodiment, the first joining portion 23 is formed by joining the sheets 22a and 22b to each other by, for example, thermocompression bonding (heat sealing), adhesive, sewing, or the like. The second joining portion 24 is joined such that the sheets 22a and 22b are detachable from each other by, for example, thermocompression bonding (heat sealing), an adhesive, or the like. The second joining portion 24 is joined so as to be peeled off due to the expansion of the water absorbing member 27 contained in the sheet material 21. In FIG. 1 (c), the pattern (satin texture) attached to the second joint portion 24 indicates that the second joint portion 24 can be peeled off with a weaker joint than the first joint portion 23.

As shown in FIG. 1 (c), the water absorbing structure 20 has irregularities on the surface by a sheet material 21 and a water absorbing member 27 dispersed and contained in the sheet material 21. Specifically, the sheet material 21 includes a first joint portion 23 and a second joint portion 24 obtained by joining the sheets 22a and 22b to each other. The water absorbing member 27 is accommodated in a region 25 defined by the first joint portion 23 and the second joint portion 24. Therefore, in the water absorbing structure 20, the thickness of the first joint portion 23 and the second joint portion 24 is thinner than the thickness of the portion in which the water absorbing member 27 is accommodated. For this reason, the part which accommodated the water absorption member 27 becomes the convex part 31, and the part of the 2nd junction part 24 becomes the recessed part 32. FIG. As shown in FIG. 1C, a plurality of groove portions are formed by the container body 11 and the water absorption structure 20 (step between the convex portion 31 and the concave portion 32). The plurality of grooves function as gas flow paths 33 when the storage container 10 is used.

Next, the operation of the storage container 10 will be described.
As shown in FIG. 3A, the suction pipe 12 of the storage container 10 is connected to the connection pipe 55 of the cuffed tracheal tube 50. Further, the discharge pipe 13 of the storage container 10 is connected to the suction source 40. When the suction source 40 is operated, the gas inside the container body 11 is sucked by the suction source 40. Then, the liquid (biological drainage) stored in the trachea 92 shown in FIG. 3B is sucked through the storage container 10 from the opening 54 of the cuffed tracheal tube 50.

As shown in FIG. 2 (a), since the container body 11 has flexibility, it is deflated by suction of the internal gas. At this time, the water absorption structure 20 accommodated in the container main body 11 has the recessed part 32 and the convex part 31 on the surface. Specifically, the water absorbing structure 20 includes a sheet material 21 and a water absorbing member 27 included in the sheet material 21. A portion accommodating the water absorbing member 27 becomes the convex portion 31, and a portion where the second joint portion 24 is formed becomes the concave portion 32. In FIG. 2A, the container body 11 is shown separated from the convex portion 31 of the water absorption structure 20 in order to make the container body 11 and the water absorption structure 20 easy to understand. The same applies to FIGS. 2B and 2C used in the following description.

A plurality of grooves (spaces) are formed by the container body 11 and the water absorbing structure 20 (the convex portion 31 and the concave portion 32). This groove has a size (width, depth) corresponding to the shape of the concave portion 32 (the shape of the convex portion 31). This groove serves as a gas flow path 33 sucked by the suction source 40. The flow path 33 is set according to the size of the recess 32 (width and depth of the recess 32). The gas inside the container body 11 is sucked into the suction source 40 by the suction source 40 shown in FIG. 3A, and the flexible container body 11 is bent. The size of the recess 32 is maintained so that the container body 11 that is bent in this manner is kept away from the second joint portion 24 of the water absorbing structure 20, that is, the container body 11 is not in contact with the second joint portion 24. Is set.

That is, in the storage container 10 to which the suction source 40 is connected, the flow path 33 for the gas sucked by the suction source is secured. The suction by the suction source 40 can be continued by the channel 33 secured in this way.

The liquid (biological drainage) sucked by the cuffed tracheal tube 50 flows into the container body 11 from the inlet 12a of the suction pipe 12 shown in FIG.
The water absorbing structure 20 includes a sheet material 21 and a water absorbing member 27 included in the sheet material 21. The sheet material 21 has water permeability. The liquid flowing into the container body 11 passes through the sheet material 21 and is absorbed by the water absorption structure 20. Therefore, the flow path 33 is difficult to be filled with the liquid. For this reason, the flow path 33 for gas can be ensured continuously.

Further, as the sheet material 21, for example, a nonwoven fabric is used. Such a sheet material 21 has liquid permeability. For this reason, the liquid inside the container main body 11 can be sucked upward by the sheet material 21, and can be spread over the entire water-absorbing structure 20. Thereby, the liquid can be absorbed by the plurality of water absorbing members 27 included in the water absorbing structure 20.

2B, the water absorbing member 27 of the water absorbing structure 20 absorbs the liquid flowing into the container body 11 and expands. Then, due to the expansion of the water absorbing member 27, as shown in FIG. 2 (c), the second joining portion 24 (see FIG. 2 (b)) is peeled, that is, the sheets 22a and 22b are peeled from each other. Due to the peeling of the second joint portion 24, the water absorbing member 27 further expands, so that a large amount of liquid can be absorbed by the water absorbing member 27.

The channel area of the channel 33 when the water absorbing member 27 is in the water absorbing state until the water absorbing member 27 starts to expand from the initial state and immediately before the second joint 24 peels (see FIG. 2B). Can be larger than the channel area of the channel 33 when the water absorbing member 27 is in the initial state (see FIG. 2A). FIG. 2C shows that at least two flow paths 33 extending in the gravitational direction are formed by the container main body 11 and the water absorbing structure 20 (for example, the first joint portion 23) in a state where the water absorbing member 27 has sufficiently absorbed water. It shows that it is maintained in a gas flowable state.

As described above, according to the present embodiment, the following effects can be obtained.
(1-1) The storage container 10 is flexible and includes a container body 11 having an inflow port 12a and an exhaust port 13a disposed therein, and is accommodated in the container body 11, and the container body 11 is provided through the inflow port 12a. 11 and a water absorption structure 20 that absorbs the liquid flowing into the interior. The water absorption structure 20 includes a sheet material 21 having water permeability and a water absorption member 27 included in the sheet material 21. A plurality of water absorbing members 27 are disposed in the container main body 11, and a plurality of grooves are formed by the container main body 11 and the water absorbing structure 20 (two adjacent water absorbing members 27). A plurality of flow paths 33 through which gas can pass through the inlet 12a and the exhaust port 13a are formed.

The storage container 10 is connected to the suction source 40, and the suction source 40 sucks the liquid into the container body 11 from the inflow port 12 a. The water absorption structure 20 accommodated in the container body 11 includes a water absorption member 27 included in the sheet material 21. Two adjacent water absorbing members 27 form a flow path 33 between the container body 11 and the water absorbing structure 20. Since the gas in the container body 11 is sucked into the suction source 40 through the flow path 33, the suction of the suction source 40 is continued and the liquid is supplied from the outside of the container body 11 through the inlet 12 a to the inside of the container body 11. Can be sucked into.

(1-2) The water absorbing structure 20 includes a plurality of water absorbing members 27 enclosed in the sheet material 21, and two adjacent water absorbing members 27 form a recess on the surface of the water absorbing structure 20, and the recess and the container A flow path 33 is formed by the main body 11. A recessed portion is formed by the two water absorbing members 27 included in one water absorbing structure 20, and the flow path 33 is easily formed between the recessed portion and the container body 11. Even when the flexible container body 11 is bent by the suction of the suction source 40, the flow path 33 can be secured by appropriately setting the size (width, depth) of the recess.

(1-3) In the storage container 10, the inlet 12 a is disposed in the lower part 11 a of the container body 11, and the exhaust port 13 a is disposed in the upper part of the container body 11. The liquid flows in from the inflow port 12a disposed in the lower portion 11a of the container body 11, and the gas in the container body 11 flows out from the exhaust port 13a disposed in the upper portion of the container body 11. For this reason, it is difficult for the liquid to reach the exhaust port 13a, and the liquid does not reach the filter 18 and the air permeability of the filter 18 is not lost before the water absorbing member 27 absorbs a sufficient amount of liquid. Therefore, the storage container 10 can be used efficiently.

(1-4) The sheet material 21 is a non-woven fabric. The nonwoven fabric has good water permeability, and the liquid flowing into the container body 11 can be well absorbed by the water absorbing member 27 through the sheet material 21 of the nonwoven fabric. The nonwoven fabric has liquid permeability. For this reason, the liquid inside the container main body 11 can be sucked upward by the sheet material 21, and can be spread over the entire water-absorbing structure 20. Thereby, the liquid can be absorbed by the plurality of water absorbing members 27 included in the water absorbing structure 20.

(Second embodiment)
Next, a second embodiment will be described.
In this embodiment, the same components as those in the above embodiment may be denoted by the same reference numerals, and all or part of the description thereof may be omitted. Moreover, about the member which does not appear in description, the code | symbol may be abbreviate | omitted in drawing.

As shown in FIG. 4A, the storage module 100 includes a storage container 110 and a suction source 140 connected to the storage container 110. The suction source 140 is attached to the upper surface of the storage container 110.

The storage container 110 has a container main body 111 and a suction pipe 112 connected to the container main body 111. The suction pipe 112 is connected to the connection pipe 55 of the cuffed tracheal tube 50 shown in FIG. The container main body 111 accommodates the water absorbing structure 20. In FIG. 4A, the water absorbing structure 20 accommodated in the container main body 111 is indicated by a solid line for easy understanding.

As shown in FIG. 4B, the container body 111 is connected to the suction source 140 via the discharge pipe 113. The suction source 140 is a piezoelectric pump, for example, and is formed in a flat shape. The piezoelectric pump is easy to finely adjust the suction amount. FIG. 4B shows a cross section in the vertical direction in FIG.

The exhaust pipe 113 is disposed at a position where the exhaust port 113a of the exhaust pipe 113 faces the second joint portion 24 of the water absorbing structure 20. When arranged in this way, the exhaust port 113a is located in the flow path 33 formed by the irregularities of the water absorption structure 20, so that it is easy to suck the gas from the flow path 33.

As shown in FIG. 4B, a support plate 150 is accommodated in the container main body 111. The support plate 150 is disposed below the water absorbing structure 20. The support plate 150 is made of, for example, plastic or acrylic resin, and is formed in a flat plate shape.

The support plate 150 facilitates securing the flow path 33 by the water absorbing structure 20. For example, when the storage container 110 that does not have the support plate is placed on a soft object (for example, a futon), the container body 111 is bent by the object and approaches the second joint portion 24 of the water absorbing structure 20. Thereby, a flow path becomes narrow. The support plate 150 prevents the container body 111 from being bent by a soft object. This prevents the channel from becoming narrow, that is, secures the channel.

As described above, according to the present embodiment, the following effects can be obtained.
(2-1) The storage module 100 includes a storage container 110 and a suction source 140 connected to the storage container 110. Therefore, it is possible to suck the biological drainage without preparing a suction source separately.

(2-2) The suction source 140 is disposed on the upper part of the storage container 110. Since the storage module 100 does not need to be suspended, the storage module 100 can be disposed at any location to store the biological drainage.

(2-3) The support plate 150 is stored in the storage container 110. The support plate 150 can be placed on a soft object such as a futon.
