Description

The present invention relates to a sample collection kit.

In a fecal occult blood test or the like for examining the presence of blood in a stool sample, a collector such as a subject or a caregiver thereof collects a part of stool as a sample. This sample collection operation is, for example, rubbing the surface of feces excreted in the cup-shaped receiving part set in the toilet bowl over a wide range with the tip of a rod-shaped collection tool, which is psychological for the collector. It is an unpleasant task with great resistance. Therefore, there has been a request to simplify the sample collection work as much as possible.

Patent Document 1 includes a cup-shaped receiving portion, a stool receiving tool having a mounting portion for setting the receiving portion on the toilet bowl, and a rod-shaped collecting tool, and the tip is arranged in the receiving portion. Described is a sample collection kit in which the collection tool is held integrally and detachably in the receiving part. The subject or the caregiver sets the receiving part on the toilet bowl via the mounting part while the collecting tool is held by the receiving part. The subject sits on the toilet bowl and excretes feces in the receiving area. As a result, a part of feces as a sample naturally adheres to the tip of the collection tool arranged in the receiving portion. After defecation, the collector removes the collection tool with the sample attached to the tip from the receiving part. Since the work of rubbing the surface of the stool with the tip of the collection tool is eliminated, the simplification of the sample collection work can be promoted.

[First Embodiment]
In FIG. 1, the sample collection kit 10 includes a stool receiving device 11, a collection tool 12, and a sample container 13. The sample collection kit 10 is a sample SP of a part of feces F (see FIG. 7 and the like) excreted by the subject S (see FIG. 6) for a fecal occult blood test for examining the presence of blood in the fecal sample. It is collected as (see FIG. 10 etc.). The sample collection kit 10 is used by a sample SP collector such as a subject S or a caregiver thereof.

The stool receiving device 11 is a device for receiving the stool F excreted by the subject S. The stool receiving device 11 has a receiving portion 14 and a mounting portion 15. The receiving portion 14 has a cup shape having a receiving port 16, a side portion 17, and a bottom portion 18. The receiving port 16 has an elliptical shape with a wide opening at the top. The side portion 17 has a substantially elliptical tubular shape extending downward from the receiving port 16 so as to gradually narrow in width. The bottom portion 18 is connected to the side portion 17 in a substantially orthogonal manner, and is formed so as to close the opening facing the receiving port 16. The receiving portion 14 receives the stool F at the receiving port 16 and retains the stool F at the bottom 18.

The mounting portion 15 is for setting the receiving portion 14 on the toilet bowl 45 (see FIG. 5), and is a wing-shaped sheet that projects symmetrically from the receiving port 16. A seal 19 is provided on the back surface of the mounting portion 15. The seal 19 is covered with a protective sheet (not shown) before the use of the stool receiving device 11, and the protective sheet is peeled off and exposed when the stool receiving device 11 is used.

The stool receiving device 11 has a form capable of closing the receiving port 16 and is made of an opaque material. In other words, the stool receiver 11 is made of a material that is flexible and has a visible light transmittance of 0 or close to 0, or is flexible and scatters or reflects visible light so that the inside is internal. It is made of a material that cannot be seen. Specifically, the stool receiver 11 is a paper formed by entwining fibers of plants or the like, or a cloth formed by weaving or knitting fibers.

The stool receiver 11 is compactly folded before use and unfolded by the collector at the time of use. Further, the stool receiving device 11 has a water-decomposable property so that the stool F can be flushed into the water of the toilet bowl 45 after the sample SP is collected. The portion formed of the opaque material may be at least the receiving portion 14, and the mounting portion 15 may be formed of a transparent material.

A binding string 20 is attached directly below the receiving port 16 of the receiving portion 14. The binding string 20 is sewn around the socket 16 as shown enlarged in the circle of the alternate long and short dash line. By pulling both ends of the binding string 20, the receiving port 16 is closed. That is, the binding string 20 functions as a closing member for closing the receiving port 16.

The collection tool 12 is a tool for collecting a part of the feces F held in the receiving portion 14 as a sample SP. The collection tool 12 is made of, for example, plastic. The collection tool 12 is a rod having a T-shaped vertical cross section, in which an attachment portion 21 is formed at the tip of a columnar rod-shaped portion and a rectangular parallelepiped grip portion 22 is formed at the base end opposite to the attachment portion 21. is there. The attachment portion 21 comes into contact with a part of the feces F in the receiving portion 14. As a result, a part of feces F adheres to the attachment portion 21 as a sample SP. The attachment portion 21 has an uneven shape having a plurality of annular grooves, so that the sample SP can be easily attached.

The grip portion 22 is gripped by the collector. The grip portion 22 is exposed to the outside of the receiving portion 14 on the outer peripheral surface of the side portion 17 of the receiving portion 14, and is covered with a removable rectangular cover 23. On the other hand, the rod-shaped portion of the collection tool 12 including the attachment portion 21 other than the grip portion 22 is inserted into the receiving portion 14 (see also FIGS. 2 and 3). That is, at least a part (rod-shaped portion in this case) of the collection tool 12 including the attachment portion 21 is integrally held by the receiving portion 14 with the attachment portion 21 arranged in the receiving portion 14.

The sample container 13 contains at least a part of the collection tool 12 after collection of the sample SP removed from the receiving portion 14, that is, a rod-shaped portion (see FIG. 12). The sample container 13 stores a diluent 24 in which the sample SP is suspended. The sample container 13 has an opening 25 for receiving the collection tool 12. The opening 25 is sealed with a disposable cap 26 before the collection tool 12 is accommodated. Although illustration and detailed description are omitted, the sample container 13 is suspended with a frayed portion for scraping the excess sample SP adhering to the adhering portion 21 from the adhering portion 21 in the previous stage of the diluent 24 and the sample SP. A filter for filtering the diluted solution 24, a storage unit for storing the filtered diluted solution 24 as an inspection liquid, and the like are provided.

The disposable cap 26 and the grip portion 22 of the collection tool 12 have the same size and the same structure. When the rod-shaped portion of the collection tool 12 is housed in the sample container 13, the grip portion 22 seals the opening 25 instead of the disposable cap 26 (see FIG. 12). That is, the grip portion 22 functions as a cap that seals the opening 25 of the sample container 13. As a method of sealing the opening 25 by the grip portion 22 and the disposable cap 26, a general method such as screwing, fitting, or press fitting can be used.

In FIGS. 2 and 3, which are enlarged views of the portion of the receiving portion 14 to which the collecting tool 12 is attached, an insertion hole 40 is formed in the side portion 17 of the receiving portion 14. Through the insertion hole 40, the tip of the collection tool 12 on which the attachment portion 21 is formed is inserted into the receiving portion 14.

An adhesive 42 (shown by hatching) is applied to the annular region 41, which is one size smaller than the outer circumference of the back surface of the cover 23. The cover 23 is detachably attached to the outer peripheral surface of the side portion 17 of the receiving portion 14 by the adhesive 42. The cover 23 covers the grip portion 22 exposed from the insertion hole 40 to the outside of the receiving portion 14, and closes the insertion hole 40 in an airtight and liquidtight manner.

At the top of the cover 23, the annular region 41 is slightly separated from the outer circumference. Therefore, the upper part of the cover 23 can be easily rolled with a finger. The cover 23 can be peeled off from the outer peripheral surface of the side portion 17 using the upper portion as a clue.

On the other hand, the grip portion 22 is not adhesively fixed to the side portion 17. After the grip portion 22 is in close contact with the side portion 17 without a gap, the cover 23 is adhered to the side portion 17 so that the grip portion 22 does not move. As a result, the grip portion 22 is held by the cover 23 in a state of being in close contact with the side portion 17 without a gap. Further, at least a part of the collection tool 12 including the attachment portion 21, that is, a rod-shaped portion, is integrally and removably held by the receiving portion 14 in a state where the attachment portion 21 is arranged in the receiving portion 14.

The grip portion 22 may be detachably attached to the side portion 17 with an adhesive, and the insertion hole 40 may be closed by the grip portion 22 itself. In this case, the cover 23 may or may not be attached.

As shown in FIG. 3, the height H1 of the attachment portion 21 (the tip 21A of the attachment portion 21 at the highest position) from the inner peripheral surface of the bottom 18 of the receiving portion 14 is the average of feces F of a general adult. The height is 3 cm or less. That is, the attachment portion 21 is arranged at a height of 3 cm or less from the inner peripheral surface of the bottom portion 18. When the inner peripheral surface of the bottom portion 18 is a curved surface, the height H1 is the height of the attachment portion 21 from the lowest position of the inner peripheral surface of the bottom portion 18.

Further, the protruding length of the rod from the insertion hole 40 (the end 40A of the insertion hole 40 at the lowest position) to the attachment portion 21 (the tip end 21B of the attachment portion 21) is received from the PL and the insertion hole 40 (end 40A). When the (horizontal) distance to the center 18A of the bottom portion 18 of the portion 14 is DC, PL is 50% or more of DC (PL ≧ 0.5DC).

The bottom 18 is sized to fit an average single dose of stool F for a general adult, with a DC of, for example, 3.5 cm. In this case, PL is 1.75 cm or more.

Next, the procedure for collecting the sample SP using the sample collection kit 10 will be described with reference to the flowchart of FIG. 4 and the state diagram of FIGS. 5 to 12. First, as shown in FIGS. 5 and 6, the collector sets the receiving portion 14 on the toilet bowl 45 via the mounting portion 15 (step ST100). More specifically, the mounting portion 15 is attached and fixed to the surface of the toilet seat 47 with a seal 19 so that the receiving portion 14 is arranged so as to float toward the center rear of the water pool portion 46.

As shown by the alternate long and short dash line in FIG. 6, the subject S sits at a position where the anus is substantially aligned with the center 18A of the bottom 18 of the receiving portion 14 and urine does not enter the receiving portion 14, and feces is placed on the receiving portion 14. Excrete F (step ST110). The receiving portion 14 may be set on the toilet bowl 45 by sandwiching the mounting portion 15 between the toilet bowl 45 and the toilet seat 47. In this case, the seal 19 becomes unnecessary.

The stool F enters the receiving portion 14 through the receiving port 16 and stays at the bottom 18 of the receiving portion 14 as shown in FIG. Note that the cover 23 is not shown in FIG. 7. The same applies to FIGS. 8 and 9 thereafter.

As shown in FIG. 3, the attachment portion 21 of the collection tool 12 is arranged at a height of 3 cm or less from the inner peripheral surface of the bottom portion 18 of the receiving portion 14. Further, as also shown in FIG. 3, the protruding length PL of the rod from the insertion hole 40 to the attachment portion 21 is 50% or more of the distance DC from the insertion hole 40 to the center 18A of the bottom 18 of the receiving portion 14. Is. Therefore, the probability that the adhering portion 21 comes into contact with a part of the stool F remaining on the bottom 18 and the sample SP naturally adheres to the adhering portion 21 can be increased.

After excretion of feces F, the collector pulls both ends of the binding string 20 to close the socket 16 (step ST120), as shown in FIG. As described above, since the receiving port 16 is in a form that can be closed by the closing member called the binding string 20 and the receiving portion 14 is made of an opaque material, the stool F is immediately taken into the eyes of the collector after the excretion of the stool F. You can avoid touching it. Therefore, it is possible to further reduce the chances that the collector feels uncomfortable in the sample collection work. Further, by closing the socket 16, the odor of feces F is also reduced, which is a secondary effect.

After closing the socket 16, the collector removes the stool receiver 11 from the toilet bowl 45. Then, as shown in FIG. 9, hold the vicinity of the receiving port 16 with one hand (here, the right hand RHD), and lightly shake the stool receiving device 11 up, down, left and right so that the sample SP is surely attached to the attaching portion 21 (step ST130). ..

After shaking the stool receiving device 11 lightly, the collector holds the vicinity of the receiving port 16 with the right hand RHD, and as shown in FIG. 10, holds the cover 23 from the receiving portion 14 with the left hand LHD which is the other hand. Peel off (step ST140).

Subsequently, as shown in FIG. 11, the collector grasps the exposed grip portion 22 with the left hand LHD, and pulls out the collection tool 12 to which the sample SP is attached to the attachment portion 21 from the insertion hole 40 (step ST150). ).

In this way, the collector almost looks at the stool F from the excretion of the stool F in step ST110 to the removal of the collection tool 12 to which the sample SP is attached to the attachment portion 21 from the receiving portion 14 in step ST150. It can be done without putting it in. Further, since the insertion hole 40 is closed by the cover 23 until the cover 23 is peeled off from the receiving portion 14 in step ST140, the feces F does not leak from the insertion hole 40.

As shown in FIG. 12A, the collector removes the disposable cap 26 from the sample container 13 and discards the removed disposable cap 26 (step ST160). Through the opening 25 exposed thereby, a rod-shaped portion that is at least a part of the collection tool 12 is housed in the sample container 13, and as shown in FIG. 12B, the opening 25 is provided by the grip portion 22 instead of the disposable cap 26. Is sealed (step ST170). After that, the collector discards the stool receiver 11 by flushing the stool receiver 11 into the water of each stool F toilet bowl 45 (step ST180).

If the grip of the collection tool does not function as a cap for the sample container, open the cap with the sample container to expose the opening, insert the collection tool into the sample container through the opening, and finally close the cap. Three work steps were required. On the other hand, in the collection tool 12, since the grip portion 22 functions as a cap of the sample container 13, the work of accommodating the collection tool 12 in the sample container 13 is the removal of the disposable cap 26 in step ST160 and the collection tool in step ST170. It only takes two steps of twelve containment. Therefore, the sample collection work can be further simplified.

The sample container 13 containing the collection tool 12 is set in a test device (not shown) and used for a fecal occult blood test. The order of some of the steps ST100 to ST180 shown in FIG. 4 may be slightly different. Specifically, the stool receiving device 11 may be discarded for each stool F (step ST180), and then the collecting tool 12 may be housed in the sample container 13 (step ST170). Further, before removing the stool receiver 11 from the toilet bowl 45 (step ST130), the disposable cap 26 may be removed from the sample container 13 and discarded (step ST160).

The receiving portion 50 shown in FIGS. 13 and 14 is provided with a bag-shaped string threading portion 53 so as to surround the outer peripheral surface of the side portion 52 directly below the receiving port 51, and the binding string 54 is passed through the string threading portion 53. It is a thing. A binding string 54 bound in a bag around such a receiving port 51 may be used as a closing member. In addition, in FIGS. 13 and 14, the illustration of the mounting portion and the like is omitted in order to avoid complication.

The closing member is not limited to the binding string 20 sewn around the receiving port 16 shown in FIG. 1 and the like, and the binding string 54 bound in a bag around the receiving port 51 shown in FIGS. 13 and 14. Anything that can close the socket may be used, and for example, a clip, a fastener (also referred to as a zipper or a chuck) or the like may be used as the closing member.

In the present invention, a closing member such as a binding string is not essential. Any form may be used as long as the socket can be closed. For example, the collector may grasp both ends of the mounting portion 15, overlap these ends, and then twist the vicinity of the socket to close the socket.

In the second and third embodiments shown below, the collection tool is composed of a main body having an attachment portion and being held by the receiving portion, and a collecting body having a grip portion and collecting the main body from the receiving portion. ..

[Second Embodiment]
The collection tool 60 of the second embodiment shown in FIGS. 15 to 19 is composed of a plate 61 as a main body and a collection body 62 that is combined with the plate 61 to collect the plate 61.

FIG. 15 shows a state before the plate 61 and the recovered body 62 are bonded, and FIG. 16 shows a state where the plate 61 and the recovered body 62 are bonded. The plate 61 is made of, for example, plastic and has rigidity. An attachment portion 63 is formed on one surface of the plate 61. The attachment portion 63 has a concavo-convex shape in which a plurality of chevron-shaped protrusions are formed, and the sample SP is easily attached as in the attachment portion 21 of the first embodiment.

The recovery body 62 is made of plastic like the plate 61. The collector 62 has a coupling portion 64 that couples to the plate 61. The connecting portion 64 is a space surrounded by a substrate 65 having the same size as the plate 61 and two elongated holding arms 66.

The substrate 65 is in contact with the surface of the plate 61 opposite to the surface on which the attachment portion 63 is formed in the state of FIG. 16 in which the plate 61 and the coupling portion 64 are bonded. The holding arm 66 is provided so as to avoid the attachment portion 63, and its tip is pointed in a wedge shape. The holding arm 66, which will be described in detail in FIG. 19, is used when the plate 61 is peeled off from the receiving portion 70 (see FIG. 17 and the like). Although not shown, the plate 61 and the joint portion 64 are provided with a guide mechanism such as a guide rail and a guide groove for smoothly guiding the plate 61 to the joint portion 64, and the plate 61 is dropped from the joint portion 64. A drop-out prevention mechanism such as a click mechanism to prevent the rail is provided.

A grip portion 67 to be gripped by the collector is formed at the other end of the collector 62 on the opposite side of the coupling portion 64. The grip portion 67 has a rectangular parallelepiped shape like the grip portion 22 of the first embodiment. Further, the grip portion 67 functions as a cap for sealing the opening 82 of the sample container 80, similarly to the grip portion 22 of the first embodiment (see FIG. 19). Therefore, as in the first embodiment, the sample collection operation can be further simplified.

As shown in FIGS. 17 and 18, the receiving portion 70 of the second embodiment has an exposed opening 72 formed on the side portion 71 thereof. The plate 61 is detachably attached to the outer peripheral surface of the side portion 71 with an adhesive 73 (indicated by hatching) so that the attachment portion 63 is exposed in the receiving portion 70 through the exposure opening 72. In other words, the exposed opening 72 is closed by the plate 61 itself. With the adhesive 73, at least a part of the collection tool 60 including the adhesive portion 63, that is, the plate 61, is integrally and removablely held by the receiving portion 70 with the adhesive portion 63 arranged in the receiving portion 70. Has been done. Further, the adhesive 73 creates a gap between the plate 61 and the outer peripheral surface of the side portion 71.

The plate 61 is exposed to the outside of the receiving portion 70 on the outer peripheral surface of the side portion 71 of the receiving portion 70. The exposed portion of the plate 61 is covered with a removable rectangular cover 74, as in the grip portion 22 of the first embodiment. The cover 74 is detachably attached to the outer peripheral surface of the side portion 71 of the receiving portion 70 by an adhesive 75 (indicated by hatching). The cover 74 covers the plate 61 exposed from the exposed opening 72 to the outside of the receiving portion 70, and closes the exposed opening 72 in an airtight and liquidtight manner. The cover 74 may not be provided as long as the exposed opening 72 is sufficiently airtight and liquid-tightly closed by the adhesive 73 with the plate 61.

Similar to the height H1 of the attachment portion 21 from the inner peripheral surface of the bottom 18 of the receiving portion 14 of the first embodiment, the exposure opening 72 (exposure at the highest position) from the inner peripheral surface of the bottom 76 of the receiving portion 70. The height H2 of the end 72A) of the opening 72 is 3 cm or less. That is, the exposure opening 72 is formed at a height of 3 cm or less from the inner peripheral surface of the bottom portion 76 of the receiving portion 70 on the side portion 71 of the receiving portion 70. As a result, as in the first embodiment, the probability that the attachment portion 63 comes into contact with a part of the stool F remaining on the bottom 76 and the sample SP naturally adheres to the attachment portion 63 can be increased.

FIG. 19 is a state diagram excerpted from the procedure for collecting the sample SP of the second embodiment. Also in the second embodiment, the procedures from step ST100 to step ST140 in FIG. 4 of the first embodiment are the same. Therefore, FIG. 19 shows the state of FIG. 19A in which the cover 74 is peeled off from the receiving portion 70 and the surface opposite to the surface on which the attachment portion 63 of the plate 61 is formed is exposed.

Similar to H2, the height H3 of the exposed opening 102 (the end 102A of the exposed opening 102 at the highest position) from the inner peripheral surface of the bottom 103 of the receiving portion 100 is 3 cm or less. That is, the exposure opening 102 is formed on the side portion 101 of the receiving portion 100 at a height of 3 cm or less from the inner peripheral surface of the bottom portion 103 of the receiving portion 100. As a result, as in the first and second embodiments, the probability that the attachment portion 93 comes into contact with a part of the stool F remaining on the bottom 103 and the sample SP naturally adheres to the attachment portion 93 can be increased.

FIG. 24 is a state diagram excerpted from the procedure for collecting the sample SP of the third embodiment. In the second embodiment, the procedure from step ST100 to step ST140 in FIG. 4 of the first embodiment is the same, but in the third embodiment, the procedure from step ST100 to step ST130 is the same. .. Further, since the covers 23 and 74 are not provided in the third embodiment, the step ST140 for peeling the covers 23 and 74 from the receiving portions 14 and 70 is omitted. Therefore, FIG. 24 shows one end 94 of the tape 91 from the state of FIG. 24A which is about to engage with the engaging portion 96 of the collector 92.

As shown in FIG. 24A, the collector engages one end 94 of the tape 91 with the engaging portion 96 of the collector 92. Since the adhesive 95 is not applied to one end 94, it can be easily rolled up and easily engaged with the engaging portion 96.

As shown in FIG. 24B, the collector moves the collector 92 in a direction perpendicular to the paper surface while rotating the collector 92 clockwise when viewed from the grip portion 97 side. As a result, the tape 91 is wound around the engaging portion 96 by shifting the position little by little with the adhesive portion 93 facing up. The collector fixes the other end of the wound tape 91 opposite to one end 94, which is the end of winding, to the collector 92 so that the wound tape 91 does not unravel. At this time, one hand of the collector holds the vicinity of the receiving port of the receiving portion 100, and the collecting body 92 is operated by the other hand to collect the tape 91.

As shown in FIG. 24C, the sample container 110 of the third embodiment stores the diluent 111 as in the sample container 13 of the first embodiment and the sample container 80 of the second embodiment. Further, the sample container 110 has an opening 112 for receiving the collection tool 90, and the opening 112 is covered with a disposable cap 113 before the collection tool 90 is accommodated.

In FIG. 24C, the collector removes the disposable cap 113 from the sample container 110 and discards it, as shown in FIG. 12A of the first embodiment and FIG. 19C of the second embodiment. Through the opening 112 exposed thereby, the tape 91 of the collection tool 90 and most of the recovery body 92 are housed in the sample container 110. As shown in FIG. 12B of the first embodiment and FIG. 19D of the second embodiment, as shown in FIG. 24D, the opening 112 is sealed by the grip portion 97 instead of the disposable cap 113. In addition, in FIG. 24C and FIG. 24D, the illustration of the adhesive 95 is omitted.

In the third embodiment, since the exposed opening 102 is closed by the tape 91 itself, the covers 23 and 74 of the second and third embodiments are unnecessary. Therefore, the number of parts can be reduced and the manufacturing cost can be reduced. Further, since the work of peeling the covers 23 and 74 from the receiving portions 14 and 70 is not required, the sample collection work can be further simplified.

Similar to the plate 61 of the second embodiment, the tape 91 can take a relatively large area of the attachment portion 93, and increases the collection amount of the sample SP as compared with the rod-shaped collection tool 12 of the first embodiment. be able to.
