TECHNICAL FIELD The present invention relates to a stool collection container for collecting stool, which is a sample.

[0002]

2. Description of the Related Art Conventionally, as a container for collecting feces as a sample, for example, one disclosed in Japanese Patent Laid-Open No. 9-54082 is known. This container is a sample collection tool,
A container body for storing the test liquid is provided, and a pipette portion for dropping an appropriate amount of the test liquid is provided at the bottom of the container body. A liquid passage having a small area is formed in the pipette portion, and an intermediate portion of the liquid passage is blocked by a thin portion.

According to this container, for example, stool collection and inspection are performed as follows.

Feces are attached to the tip of the sample collecting tool.

The tip of the sample collecting tool is inserted into the container body through the opening on the tip side, and the sample collecting tool is directly attached to the container body as it is. At this time, the fecal particles attached to the tip of the sample collecting tool are dispersed in the liquid, so that the test liquid becomes a suspension.

After transporting the container, at the time of inspection, the thin portion of the pipette portion is pierced by a needle or the like to bring the liquid passage into a circulating state. Then, with the pipette portion facing downward, the middle abdominal portion of the container body is pressed with a finger or the like, and the suspension is dropped from the pipette portion to an appropriate place to perform the inspection.

[0007]

SUMMARY OF THE INVENTION In the above-mentioned stool collection container,
There are the following issues to be solved.

That is, the liquid passage of the pipette portion must be extremely thin so that an appropriate amount of liquid can be dropped, and a thin portion must be formed in the middle of this liquid passage, which makes molding thereof difficult. . Further, it is necessary to provide a filter to prevent the invasion of the precipitate into the liquid passage, resulting in a complicated structure and high cost.

In view of such circumstances, it is an object of the present invention to provide a stool collection container having a simple structure and capable of easily and accurately collecting a stool suspension.

[0010]

Means for Solving the Problems As means for solving the above problems, the present invention is capable of adhering a test liquid storage container which is open at the tip side and can store a test liquid inside, and a fecal sample And a sample collecting member that can be attached in close contact with the tip opening of the test liquid storage container with the sample attachment part being inserted into the test liquid storage container. In a stool collection container, the body of the test liquid storage container is integrally molded into a shape that opens on both the tip side and the bottom side, and a lid is attached to the bottom side opening of the container body to close the opening. At the same time, the lid is formed with a nozzle indentation recessed from the outer surface thereof toward the tip side of the container body so that the suspension suction nozzle can intrude, and the bottom wall of the nozzle intrusion recess is Thin-walled with smaller thickness in the axial direction than the part It is obtained by the.

In this container, the suspension suction nozzle can be inserted into the nozzle intrusion recess and the thin portion can be pierced by the nozzle to suck the suspension in the container. Further, since the thin wall portion is not formed in the middle of the liquid passage of the pipette portion that is extremely narrow, but the bottom wall of the nozzle entry recess having a relatively large area is the thin wall portion, the lid can be easily formed.

With respect to this lid, the entire lid including the thin portion may be integrally formed, or a through hole having a shape into which the suspension suction nozzle can enter is formed in the main body of the lid. You may make it stick the sealing film which comprises the said thin part in the position which blocks the bottom opening of this through-hole. In the case of the former, it is possible to further reduce the cost by reducing the number of parts and man-hours. Moreover, by making the surface of the thin-walled part on the tip side of the container body and the surface of the other part on the tip-side of the container main body flush, the molding can be further facilitated, and the thinned part can be the deepest part of the nozzle entry recess. The thin-walled portion can be more reliably protected from the outside by being positioned at.

By forming an ear portion on the peripheral portion of the lid and inserting the lid to the position where the ear portion and the bottom side end surface of the container body contact each other, the lid can be easily positioned with a simple structure. In addition, the mounting state can be stabilized.

Further, a flange portion that is thicker than other portions and protrudes outward in the radial direction of the container is formed at the bottom side end portion of the container body, and the outer shape of the flange portion and the ear portion can be made substantially equal. For example, it is possible to effectively reinforce the structure on the bottom side while making it compact. Then, by welding these ears and the flange, higher sealing performance can be obtained.

The lid may have a solid structure except for the nozzle entry concave portion, but the lid is formed on the outer wall fitted to the front end side opening of the container body and on the inner side of the outer wall. By providing an inner side wall surrounding the nozzle intrusion recess and forming a recess having a bottom wall thicker than the thin part between the outer side wall and the inner side wall, the lid can be covered by this recess. The weight can be reduced, and the deformation of the outer wall after molding is reduced to stabilize the adhesion between the outer wall and the inner peripheral surface on the bottom side of the container body, while the inner wall surrounding the nozzle intrusion concave portion allows the periphery of the thin portion to be surrounded. It can be locally reinforced to effectively protect the thin part.

In this stool collection container, at least a part of the container body has a flat cross section, or a female screw portion is integrally formed at the tip of the test liquid storage container. It is possible to integrally form a male screw portion that can be screwed, or to extend a handle portion having a handle hole having an inner diameter substantially equal to the outer diameter of the sample attachment portion from the female screw portion to the bottom side. .

Further, by providing a mountable dropper configured to be fittable into the nozzle entry recess of the lid and capable of dropping the suspension by breaking through the thin portion in the fitted state, It is possible to implement not only the method of collecting the suspension using the suspension suction nozzle, but also the method of dropping the suspension from the bottom side of the container. It also becomes possible.

The tip side portion of the test liquid storage portion 12 is the female screw portion 1 described above.
The tapered portion 12a is for smoothly transitioning from the sectional shape of No. 1 to the sectional shape of the test liquid storage unit 12. A label 14 is affixed to the outer peripheral surface of the test liquid storage portion 12, and the name and the like of the person to be inspected can be written on the label 14.

The bottom portion side of the test liquid storage portion 12 is opened straight, and a flange portion 15 is formed at the peripheral portion of this bottom portion side opening. The flange portion 15 is thicker than other portions and protrudes in the container radial direction, and has a substantially rectangular shape in the illustrated example. Then, the lid 70 is fitted into the bottom side opening of the container body, and the opening is closed by the lid 70.

The entire lid 70 is integrally molded of synthetic resin, and has a bottom wall 71 as shown in FIG. 3, an outer wall 72 rising from the peripheral edge of the bottom wall 71, and the outer wall 72. It integrally has an inner side wall 73 that stands up in the inner region. The outer peripheral shape of the outer wall 72 is set to be equal to or slightly smaller than the shape of the bottom side opening of the test liquid storage container 10, and can be fitted into this bottom side opening. The inner wall 73 has a cylindrical shape, and a part of the inner wall 73 overlaps with the outer wall 72 to be integrated.

In other words, a circular nozzle intrusion recess 75 is formed inside the inner wall 73, and a pair of left and right recesses 76 is formed between the inner wall 73 and the outer wall 72. The nozzle entry recess 75 has an area into which the suspension suction nozzle 54 can enter, and extends from the outer side surface (upper side surface in FIG. 3B) of the lid 70 to the container tip side (lower side in FIG. 3B). ) Towards the bottom. The bottom wall portion of the nozzle entry recess 75 is a thin portion 77 having a smaller wall thickness than the bottom wall 71 of the other portion. The thickness dimension of the thin portion 77 is set so small that the suspension suction nozzle 54 can be broken through as it is.

At the peripheral portion of the outer wall 72, an ear portion 74 is formed which projects more outward than other portions. In this embodiment, the shape of the ear portion 74 is set to be substantially the same as the shape of the flange portion 15, and the ear portion 74 has the shape of the flange portion 1.
5, the outer wall 72 reaches the position where it abuts the test liquid storage container 10.
The test liquid storage container 10 is fitted with the lid 70 by being fitted into the bottom side opening of the test liquid storage container 10.

In order to secure the sealing of the inside of the container by mounting the lid 70, it is necessary to completely join the ear portion 74 and the flange portion 15 by using a means such as ultrasonic welding.
More preferable.

Similar to the container body described above, the sample collecting rod 20
Also, in this embodiment, it is integrally molded of synthetic resin and has a knob portion 21, a male screw portion 22, and a sampling rod 23 in order as shown in FIG. Male thread 2
A male screw 22a is engraved on the screw 2 to be screwed with the female screw portion 11 of the test liquid storage container. Collecting rod 23
Has a uniform diameter, and a portion near the male screw portion 22 is a bent portion 23a that bends at an obtuse angle.
The portion closer to the tip end is bent in a direction different from the bending direction of the bending portion 23a (the opposite direction in the illustrated example). At the tip of the sampling rod 23, the outside of the curved surface (Fig. 4 (b))
Then, a plurality of sample collection grooves 23b that are open to the upper side) are formed.

Next, a method of inspecting stool using this stool collection container will be described.

1) Sampling of specimen As shown in FIG. 5A, the knob portion 2 of the specimen collecting member 20
1 is pinched with a finger or the like, and the tip of the sampling rod 23 is pressed against the feces as a sample and rubbed to allow the sample to enter the sample collecting groove 23b at the tip. At this time, in order to secure a sufficient sample collection amount, it is preferable to bring the sampling rod 23 as close to horizontal as possible. However, when the sampling rod 23 has a linear shape as shown in FIG. The closer the sampling rod 23 is to the horizontal direction, the closer the knob portion 21 is to the sample, and the higher the possibility that it will adhere to the finger or the like. On the other hand, in the case of the sample-collecting rod 23 whose middle part is bent as shown in (a) of the figure, it is possible to secure a sufficient distance between the sample and the knob part while bringing the distal end part thereof closer to the horizontal direction, so It is possible to prevent the sample from adhering.

However, in the present invention, the shape of the sampling rod 23 is not particularly limited and may be the one shown in FIG. 5 (b).

2) Mounting of sample collecting member As shown in FIG. 6, with the tip of the test solution storage container 10 facing upward and the test solution 17 stored therein, from the top (that is, the female screw portion 11 side). From) inspection liquid storage container 10
The tip of the sample collecting member 20 is inserted therein, and the sample collecting member 20 is further rotated to screw the male screw portion 22 thereof into the female screw portion 11, and the both are brought into close contact with each other at this portion. Here, when the tip portion of the sampling rod 23 (that is, the portion to which the sample adheres) passes through the handling hole 13a of the handling unit 13, the handling unit 13 scrapes off the excess sample on the sampling rod 23. Only an appropriate amount of the sample that has entered the sample collection groove 23b is immersed in the test liquid 17. This sample is dispersed in the liquid to make the test liquid 17 into a suspension.

3) Collection of Suspension, etc. The stool collection container in the state shown in FIG. 5 is transported as it is to a place having an appropriate inspection facility, and the above-mentioned suspension is sampled and analyzed. FIG. 7 shows an example of a device for automatically collecting the data.
And shown in FIG.

This device comprises a container holding member 40, a suspension suction device 50, and a transfer device 60.

The container holding member 40 is in the shape of a container that opens upward, and has a small diameter hole 41 that is slightly larger than the female threaded portion 11 of the stool collection container and a large diameter that has a cross-sectional shape almost equal to the flange portion 15. Hole 42 and a tapered portion 43 at the boundary between both holes 41, 42. Then, the stool collection container is held in the container holding member 40 by the knob portion 21.
By inserting from the side and mounting the tapered portion 12a on the tapered portion 43, the stool collection container can be held with the bottom side lid 70 facing upward as shown in FIG.

In the suspension suction device 50, a suspension suction nozzle 54 extends downward from a device main body 52 containing a pump, and a lower end surface 54 of the suspension suction nozzle 54.
a is cut diagonally and sharpened. Carrier 60
Is a cylinder 61 installed on the ground, an elevating shaft 62 that is vertically moved by the cylinder 61, and an elevating shaft 6
A swivel device 63 that swivels the horizontal arm 64 at the top of the second arm 2, and the suspension suction device 50 is fixed to the tip of the horizontal arm 64. And is to be transported in the vertical direction.

In this apparatus, as shown in FIG.
It is held in the container holding member 40 with 0 directed upward. Then, the suspension suction nozzle 54 is inserted into the nozzle entry recess 7
5 is set at a position immediately above (the position shown by the solid line in FIG. 8) and lowered as it is, and the thin portion 7 is formed on the lower end surface 54a of the nozzle.
7 is pierced and further immersed in the test liquid (suspension) 17 therein (the position indicated by the chain double-dashed line in the figure). At this position, the pump is operated as it is to suck a certain amount of the suspension liquid into the suspension liquid suction nozzle 54, and then the suspension liquid suction nozzle 54 is pulled up and moved to another place to remove the suspension liquid. The suspension 17 is dropped in a suitable place (for example, a reaction container).

Therefore, according to this stool collection container, stool collection can be performed by a simple method, and automation of the work can be easily promoted.

Further, the structure of the lid 70 is simple, unlike the conventional lid having a pipette portion like the lid of a container, and it is not necessary to provide a small-diameter liquid passage. Further, instead of forming a thin portion in the middle of such a small diameter liquid passage,
Since the bottom wall of the nozzle entrance recess 75 having a large area to the extent that the suspension suction nozzle 54 can enter is a thin wall, molding is easy and mass production at low cost is possible.

In particular, in this embodiment, the thin portion 7 is
Since the surface of the No. 7 toward the container tip side (the lower surface in FIG. 3B) is flush with the surface of the bottom wall 71 of the other portion, the molding is easier, and the thin wall portion 77 is provided with the nozzle penetrating recess. 75
By locating the thin-walled portion 77 at the deepest portion, the thin-walled portion 77 can be protected most effectively from the outside, and it is possible to reliably prevent the thin-walled portion 77 from coming into contact with foreign matter and being accidentally broken. Further, since the thin-walled portion 77 is soiled with the suspension before the suspension suction nozzle 54 is inserted, the outer peripheral surface of the suspension suction nozzle 54 is soiled when the thin-walled portion 77 is pierced. However, by arranging the thin portion 77 at the deepest position, there is also an advantage that the area where the outer peripheral surface of the suspension suction nozzle 54 is contaminated when it is inserted can be minimized.

Further, since the bottom side opening of the container body is simple, the female screw portion 11 is formed integrally with the liquid storage container 10 and the handle portion 13 is formed integrally with the test liquid storage container 10. Alternatively, it becomes easy to make the cross-sectional shape of the test liquid storage portion 12 flat, and the formation of the female screw portion 11 makes it possible to reliably prevent the suspension 17 from leaking from the tip side of the container. By forming 13, the amount of the sample to be dispersed in the suspension 17 can be made constant, and the flattening of the test liquid storage part 12 facilitates the sticking of the label 14 to the outer peripheral surface thereof, and The effect that the name and the like can be easily written on the label 14 is obtained.

In particular, in this embodiment, a thick reinforcing flange portion 15 is formed at the bottom of the container to prevent deformation,
Since the lid 70 is fitted inside the flange portion 15, it is possible to prevent the sealing performance from being deteriorated due to the deformation.

The ear portion 74 may be omitted as appropriate, but the ear portion 74 is formed and the lid 70 is fitted into the opening to a position where the ear portion 74 and the end surface on the container bottom side contact with each other.
The positioning of 0 can be performed easily and the fixed state can be stabilized. Particularly, in the above embodiment,
Since the outer shape of the ear portion 74 and the outer shape of the flange portion 15 are made substantially equal to each other so that they are in contact with each other, it is possible to efficiently reinforce the container bottom portion with a compact configuration.

In this embodiment, the lid 70 is integrally molded including the thin portion 77, but as shown in FIGS. 9A to 9C as the second embodiment, for example. In place of the nozzle intrusion recess 75, a through hole 75 'having a cross-sectional shape equivalent to this is made to penetrate in the vertical direction,
A sealing film 78 may be attached to the bottom wall 71 as a thin portion so as to close the bottom opening. In this case, as the sealing film 78, a coating layer for preventing corrosion made of polyethylene or the like is formed on both front and back surfaces of a thin base material made of a metal such as aluminum or a synthetic resin, and a synthetic layer for heat welding is formed on the back surface. A composite film coated with a resin (basically the same material as the container body) can be used.

However, in the present invention, the above-mentioned coating layers are not essential, and the sticking means of the sealing film 78 can be applied by ultrasonic welding or adhesion by an adhesive, in addition to the above-mentioned heat welding.

In addition, the present invention can take the following forms, for example.

(1) When the cross-sectional shape of the test liquid storage container 10 is made flat, the shape is not limited to an ellipse. The advantage is that the label 14 can be easily filled.

(2) In the first and second embodiments, the handle portion 13 and the flange portion 15 can be omitted as appropriate. However, by forming the flange portion 15, the other portion is thinned to reduce the weight of the container, and
There is an advantage that the deformation by 5 can be suppressed and the sealing by the lid 70 can be more surely maintained in good condition.

(3) In the lid 70, the pair of left and right recesses 76 can be omitted. That is, the outer wall 72 and the inner wall 73 may be integrated and solidified, and only the nozzle intrusion recess 75 may be recessed therein. However, by securing the concave portion 76 (that is, the outer wall 72 and the inner wall 73 are provided side by side), the weight of the lid 70 is reduced, and the outer wall 7 after molding is formed.
The inner wall 73 reinforces the peripheral portion of the thin portion 77 while reducing the deformation of the second portion 2 and stabilizing the outer shape of the thin portion 7.
7 can be effectively protected.

(4) In FIG. 7, the container holding member 40 is fixed to the ground and the suspension suction device 50 is conveyed to both the vertical direction and the horizontal direction. The suspension sucking device 50 is configured to convey only in the vertical direction, and instead, for example, the container holding member 40 and the reaction container are arranged side by side and placed on a moving table such as a turntable, and the suspension suction device is alternately sucked. It may be configured so that it can be conveyed horizontally to a position below the nozzle 54.

(5) In each of the above embodiments, the test liquid storage container 10 is provided with the female screw portion 11 at the tip and the sample collecting member 20 is provided with the male screw portion 22, but these are omitted.
For example, the outer peripheral surface of the sample collecting member 20 and the test liquid storage container 10
It is possible to seal the inside of the container by interposing a seal member between the inner peripheral surface of the tip portion of the container and the inner peripheral surface of the container. However, if the female screw portion 11 and the male screw portion 22 as described above are formed integrally with the test liquid storage container 10 and the sample collecting member 20, respectively, there is an advantage that reliable sealing can be achieved with a simple structure having a small number of parts.

(6) As described above, in the fecal sampling container according to the present invention, the thin wall portion 77 is basically the suspension suction nozzle 54.
It is used for a method of breaking through from above and sucking the suspension as it is with the nozzle 54, but it is possible to drop the suspension directly into a proper place from the bottom wall of the container by using a wearable dropper having an appropriate structure. The method can also be used.

For example, as shown in FIG. 10 as the third embodiment, the outer diameter of the nozzle main body 82 is made substantially equal to the inner diameter of the nozzle intrusion concave portion 75 shown in the first embodiment, and its intermediate portion. If the nozzle main body 82 is fitted and fixed in the nozzle intrusion recess 75 until the collar 84 is formed and the collar 84 hits the inner wall 73, the tip end surface 82a pierces the thin portion 77 during the fitting. The suspension can be dropped from the liquid passage 81 by directing the wearable dropper 80 downward.

That is, the stool collection container according to the present invention can be applied with two collection methods depending on the suspension inspection method and the like.

[0056]

As described above, according to the present invention, the main body of the test liquid storage container is integrally formed into a shape that is open at both the front end side and the bottom side, and the lid is mounted in the bottom side opening of the container main body. The lid is closed with the opening, and the lid is formed with a nozzle indentation recessed from the outer surface toward the front end side of the container body, the nozzle intrusion recess having a shape into which the suspension suction nozzle can enter. Since the bottom wall of the is a thin portion with a smaller thickness dimension in the axial direction of the container than other parts, it is a simple structure that can be mass-produced at low cost, and the specimen is attached to the specimen attaching portion of the specimen collecting member. After mounting the test liquid in the test liquid storage container to make the test liquid in the container a suspension of the sample, the thin wall part is pierced from above with the suspension suction nozzle with the bottom wall of the container facing up. The suspension in the test solution storage container is sucked as it is with the suction nozzle. It is possible to realize a method of inspecting a stool that is dropped into place.

Here, in the case where the entire lid including the thin portion is integrally formed, the number of parts and the number of steps can be reduced to further reduce the cost. In particular, by making the surface of the thin-walled part on the tip side of the container body and the surface of the other part on the tip-side of the container main body flush, the molding can be further facilitated, and the thinned part can be the deepest part of the nozzle entry recess. It can be effectively protected from the outside by being located at.

By forming an ear portion on the peripheral portion of the lid and inserting the lid to the position where the ear portion and the end surface on the bottom side of the container body contact each other, the lid can be easily positioned with a simple structure. In addition, the mounting state can be stabilized.

Further, a flange portion which is thicker than other portions and protrudes outward in the radial direction of the container is formed at the bottom side end portion of the container body, and the outer shape of the flange portion and the ear portion can be made substantially equal. If so, the bottom of the container can be efficiently reinforced with a compact structure. Then, by welding these ears and the flange, higher sealing performance can be secured.

The lid is provided with an outer wall fitted to the front end side opening of the container body, and an inner wall formed inside the outer wall and surrounding the nozzle intrusion recess. If a recess having a thicker bottom wall than the thin portion is formed between the wall and the wall, the weight of the lid can be reduced by the amount of this recess, and the deformation of the outer wall after molding can be reduced to reduce the deformation of the outer wall. The effect of being able to effectively protect the thin-walled portion by locally reinforcing the periphery of the thin-walled portion by the inner side wall that surrounds the nozzle entry recess while stabilizing the adhesion to the bottom-side inner circumferential surface of the container body.

In this stool collection container, for example, by making the cross-sectional shape of at least a part of the container body flat, a label or the like can be stably attached to this part and the label or the like can be attached. The effect of making it easy to fill in is obtained.

Further, a female thread portion is integrally formed at the tip portion of the test liquid storage container, and a male thread portion which can be screwed with the female thread portion is integrally formed with the sample collecting member, whereby a reliable seal can be achieved. .

Further, by extending a handle portion having a handle hole having an inner diameter substantially equal to the outer diameter of the specimen attaching portion from the female screw portion to the bottom side, the amount of the specimen dispersed in the test solution is stabilized. be able to.

Further, a plurality of types can be provided by providing a mounting type dropper which is constructed so that it can be fitted into the nozzle intrusion concave portion of the lid and which can penetrate the thin portion and drop the suspension in the fitted state. The suspension collection method can be realized, and the suspension collection method can be selectively used depending on the case.
