Description

  The present invention relates to a stool collection container for collecting stool during a stool inspection.

  Conventionally, various types of stool collection containers have been proposed as a stool collection container for collecting stool during stool inspection (stool test), but many of them have a stool collection rod provided with a spiral groove at the tip. A lid and a container body in which a storage solution is stored are provided (for example, see Patent Document 1).

  In this type of stool collection container, when collecting the stool, the lid is removed, the stool is scraped into the spiral groove provided at the tip by piercing the stool, etc. The stool collected in the preservation solution contained in the container main body is suspended by returning the stick into the container and closing the lid. The stool collected in this way is used for inspection by filtering the suspension. For example, in the stool collection container described in Patent Document 1, the storage solution is stored in the container body. The suspension is squeezed with fingers to extrude the suspension, and the suspension is filtered out with a filter inserted into the pipette member fixed to the tip of the storage solution storage unit.

  By the way, in the squeeze container of the type which squeezes the container main body and drops the suspended liquid which suspended the stool while filtering, like the stool collection container described in patent document 1, It is desirable to mold the container body using a flexible material so as not to interfere.

  However, as a result of repeated intensive studies by the present inventors, when the stool collection container includes a lid having a stool collection stick, a container body containing a storage solution, and a drip cap for dripping the suspension, In order to squeeze the container body and easily drop the prescribed amount, it was found that it was necessary to be able to drop with a smaller squeeze force.

  The present invention has been made in view of the above circumstances, and in a stool collection container that squeezes a container body and drops a suspended liquid in which stool is suspended, the container strength and moisture resistance permeation are reduced. An object of the present invention is to provide a stool collection container that can squeeze the container body and easily drop a prescribed amount without reducing the performance.

  A stool collection container according to the present invention is attached to a lid body having a stool collection rod while sealing the inside of the container, a cylindrical container body provided with a pouring hole on the distal end side, and a distal end side of the container body. And a dripping cap, and a thin-walled portion in which the inner peripheral surface of the side wall is recessed is formed in a portion near the tip of the container main body.

  According to the present invention, in a stool collection container for stool inspection that squeezes the container body and drops a suspension containing stool, the container body is squeezed without reducing container strength and moisture permeability. Thus, the prescribed amount can be easily dropped.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

  A stool collection container 1 shown in FIG. 1 and FIG. 2 is for collecting stool during a stool examination, a lid 2 for sealing the inside of the container, a cylindrical container body 3 for storing a storage solution, The inside plug 4 is mounted in the container body, and the dropping cap 5 is mounted on the distal end side of the container body 3 by screwing.

  As shown in FIG. 3, the lid body 2 has a stool collection rod 2b for collecting feces together with a lid portion 2a for sealing the inside of the container. A spiral groove 2c engraved in a spiral shape is formed on the distal end side of the stool collection rod 2b, and in order to collect feces with the stool collection rod 2b, the lid 2 is removed from the container, and the stool collection rod The feces are collected by scraping the feces 2b into the stool and scraping it with the spiral groove 2c. After the stool is collected, the lid 2 is attached to the container again, the stool collection rod 2b is returned to the container body 3, and the collected stool is suspended in the storage solution stored in the container body 3. .

In the present embodiment, the spiral groove 2c is formed on the distal end side of the stool collection rod 2b. However, the present invention is not limited to this as long as feces can be reliably collected. For example, it is possible to provide a plurality of grooves that are orthogonal to the longitudinal direction and go around the distal end side of the stool collection rod 2b. In addition, one or more concave portions or through holes having various shapes may be provided. Since the stool has various properties such as solid stool, soft stool, and liquid stool, various stool collection devices have been devised for collecting these stool.
Moreover, in order to improve the visibility of the stool adhering to the stool collection rod 2b, it is preferable to color the stool collection rod 2b with a white or light color with high brightness. In particular, it is more preferable that the color is pale green, which is close to the complementary color of fecal color (brown to tan).

Moreover, in this embodiment, the cover body 2 is the annular convex part 4g formed along the circumferential direction on the outer peripheral surface of the inner plug 4, and the annular convex part formed along the circumferential direction on the inner peripheral surface of the lid part 2a. It is mounted by fitting with 2f to seal the inside of the container, but the mounting means of the lid 2 is not limited to this. If the inside of the container can be sealed, for example, although not particularly illustrated, by screwing with a screw provided on the inner peripheral surface of the lid portion and a screw provided on the outer peripheral surface of the inner plug 4, A lid may be attached.
In order to improve the sealing performance when the lid 2 is attached to the container, although not shown in particular, a protrusion that contacts the end edge of the inner plug 4 is formed in an annular shape on the inner surface of the lid 2a. Is also effective.

  Moreover, in this embodiment, although the sealing part is ensured by sticking the cover part 2a to the inner peripheral surface of the inner plug 4, it is between the outer peripheral surface of the inner plug 4 and the cover part 2a. A gap is formed. By forming a gap between the outer peripheral surface of the inner stopper 4 and the lid 2a, when the stool collection rod 2b from which the stool is collected is returned to the container, the stool is mistakenly attached to the edge of the inner stopper 4 In the case where the stool adheres to the stool, the stool can be allowed to flow into the gap so as not to protrude outside the stool collection container 1.

  Such a lid body 2 is preferably formed by integrally molding the lid portion 2a and the stool collection rod 2b by injection molding, but they may be molded separately. If the inside of a container can be sealed with the cover part 2a, and the stool collection rod 2b has the hardness which can be stabbed into feces, the specific structure of the cover body 2 will not be specifically limited.

Then, the suspension obtained by suspending the collected stool in the preservation solution squeezes the container body 3 and flows out from the extraction hole 3a provided at the distal end portion of the container body 3. It is dripped from the dripping cap 5 with which it was mounted | worn.
Each member which comprises the stool collection container 1 can be manufactured by injection molding etc., for example using thermoplastic resins, such as a polypropylene and polyethylene. The container body 3 uses a polyolefin resin such as linear low-density polyethylene, low-density polyethylene, or polypropylene to enable squeezing, and among these, the squeeze property, moisture permeation resistance, or injection moldability is used. A chain low density polyethylene is preferred.

The container body 3 is preferably formed into a cylindrical shape or a cylindrical shape having an elliptical or oval cross section, and a thin-walled portion 3t in which the inner peripheral surface of the side wall is recessed at a portion near the tip of the container body 3. Is formed.
Thereby, the container body can be squeezed and a prescribed amount can be easily dropped without impairing the squeeze property of the container body 3 and without lowering the strength and moisture permeability.
FIG. 4 is an enlarged view of a main part of a portion surrounded by a one-dot chain line in FIG.

  Moreover, the site | part which forms the thin part 3t in the container main body 3 makes it easy to squeeze the container main body 3 with a finger | toe by an operator, and is a site | part which the container main body 3 deform | transformed by squeezing does not interfere with another structural member. . More specifically, in a state where the inside of the container is sealed with the lid body 2 and the dripping cap 5 is attached to the container body 3, the container body is separated from the tip of the stool collection rod 2 b or the surface facing the vicinity thereof. It is preferable to form the thin portion 3t in the range R up to the point where the third step portion 3g is reached.

Here, although depending on the shape and size of the stool collection container 1, the tip of the stool collection rod 2b or the vicinity thereof is a range r ₁ approximately ± 10 mm along the longitudinal direction from the tip of the stool collection rod 2b. The term “near to the step 3 g of the container body 3” means a distance r _{2 of} 1 mm or more along the longitudinal direction from the step 3 g on the tip end side of the container body 3.
The step portion 3g of the container main body 3 is a portion formed along with the formation of the mounting portion for mounting the drip cap on the distal end side of the container main body 3.

  Moreover, as shown in the DD cross section of FIG. 4 in FIG. 5, the thin portion 3 t may be provided over the entire circumference of the inner peripheral surface of the side wall of the container main body 3. It is also possible to provide a plurality of groove-like thin portions 3t extending in the longitudinal direction (see FIG. 6). Furthermore, the thin part 3t may be formed by denting the inner peripheral surface of the side wall into an elliptical cross section (see FIG. 7).

  Furthermore, the ratio t / T of the thickness t of the thin portion 3t to the thickness T of the side wall is preferably 0.2 to 0.95. When t / T is larger than 0.95, there is no difference between the thin portion 3t and other portions, and the effect of the present invention is hardly obtained. Moreover, if t / T is smaller than 0.2, the fluidity of the molten resin when the container body 3 is injection-molded may be hindered, and the container body 1 may be insufficiently strong.

In the present embodiment, the container body 3 has a partition wall 3b in which a pouring hole 3a is formed on the distal end side, and a dropping cap 5 that is attached to the distal end side of the container body 3 by screwing (screw tightening). Has a sealing body 5a for sealing the pouring hole 3a. Thereby, the stool collection container 1 of this embodiment is opened by loosening the screwing of the dropping cap 5 (see FIG. 2), and resealed by retightening the dropping cap 5.
2 is a cross-sectional view of FIG. 1A-A in a state in which the screw cap of the dropping cap 5 is loosened.

  In this embodiment, the 1st cyclic | annular convex part 3d is formed in the predetermined | prescribed position along the circumferential direction in the outer peripheral surface at the front end side of the container main body 3 with which the dripping cap 5 is mounted | worn. At the same time, on the inner peripheral surface of the dropping cap 5, a second annular convex portion 5b is formed at a predetermined position along the circumferential direction.

  As shown in FIG. 2, the position where the first annular convex portion 3d is formed on the outer peripheral surface on the distal end side of the container body 3 and the position where the second annular convex portion 5b is formed on the inner peripheral surface of the dropping cap 5 are dropped. When the sealing body 5a is separated and the pouring hole 3a is opened by loosening the screwing of the cap 5, the first annular convex part 3d and the second annular convex part 5b are adjusted as appropriate. To do. By doing in this way, it can be sensed that the stool collection container 1 is in an opened state by the feeling that the first annular convex portion 3d and the second annular convex portion 5b are in contact with each other. It is possible to prevent the dropping cap 5 from falling off due to being loosened too much.

  Further, in the present embodiment, in order to screw the dropping cap 5, the main body side thread 3 e is formed on the outer peripheral surface on the distal end side of the container main body 3, and the cap side is formed on the inner peripheral surface of the dropping cap 5. A thread 5c is formed. When forming these threads, the main body side thread 3e of the container body 3 and the cap side thread 5c of the dropping cap 5 are in contact with the first annular protrusion 3d and the second annular protrusion 5b. It is preferable that the height of one or both of the main body side thread 3e and the cap side thread 5c is reduced or removed so that the two can get over each other.

Here, FIG. 8 shows an example of a configuration that allows the main body side thread 3e of the container body 3 and the cap side thread 5c of the dropping cap 5 to cross over each other.
8 (a) is obtained by reducing the height of the threaded range extending from screw threads 5c ₁ located on the second annular projection 5b of the cap side screw bar 5c of the drip cap 5 to 5c _2. FIG. 8B shows a screw thread in a range extending from the screw threads 3e ₁ to 3e ₂ located on the side of the main body side screw thread 3e of the container body 3 away from the first annular convex portion 3d (part of the screw thread in the figure). (Represented by a chain line). FIG. 8 (c), by removing the screw thread in the range of screw threads 3e ₁ of the main body side screw thread 3e of the container body 3 (indicated by a chain line a part in the figure), the cap-side screw bar 5c of the drip cap 5 The height of the thread in the range extending from 5c ₁ to 5c ₂ is reduced.

  Therefore, when the stool collection container 1 is opened and the first annular convex portion 3d and the second annular convex portion 5b are in contact with each other, the dropping cap 5 is idle with respect to the container main body 3. In this manner, since the inspection is performed without removing the drip cap 5 from the container main body 3 by rotating the drip cap 5 with respect to the container main body 3, contamination of the drip cap required for re-sealing is required. Loss is prevented.

  Furthermore, in this embodiment, as shown in FIG. 9, the tape-like member 7 in which the perforation 7 a is formed along the circumferential direction is located at the boundary between the container body 3 and the drip cap 5. It is preferable to wrap around. By doing in this way, loosening of the dripping cap 5 before opening of the stool collection container 1 (before inspection) is prevented, and confirmation of the presence or absence of opening becomes easy.

  On the other hand, the base end side of the container main body 3 is opened so that the inner plug 4 can be mounted in the container main body 3, and when the inner plug 4 is mounted in the container main body 3, the inner peripheral surface of the container main body 3. And the outer peripheral surface of the inner plug 4 are in close contact with each other in a liquid-tight manner so that the storage solution stored in the container body 3 does not leak out.

  As shown in FIGS. 10 and 11, the distal end portion of the inner plug 4 mounted in the container main body 3 has a bottom surface 4a orthogonal to the longitudinal direction, and the lid body 2 has a sample at the center of the bottom surface 4a. A scraping portion 4b into which the toilet bar 2b can be inserted is formed. The scraping portion 4b is for removing excess stool adhering to the stool collection rod 2b when returning the stool collection rod 2b from which the stool has been collected into the container, and in the present embodiment, at the center of the bottom surface 4a. It is formed as an open cylindrical part. The scraping portion 4b is such that the stool collection rod 2b is in liquid-tight contact with the inner peripheral surface of the scraping portion 4b, and excess feces are removed when the stool collection rod 2b slides on the inner peripheral surface of the scraping portion 4b. Thus, a certain amount of stool filling the spiral groove 2 c can be suspended in the storage solution stored in the container body 3.

  The outer shape of the inner stopper 4 constituting the scraping portion 4b has a tapered shape that gradually decreases from the middle of the inner stopper 4 toward the scraping portion 4b in order to reliably guide the stool collection rod 2b to the scraping portion 4b. You can also.

However, in such a shape, a gap is formed between the side surface of the tapered portion and the inner surface of the container body, and the volume of the storage solution storage portion is increased. If the volume of the storage solution storage part is too large, the tip of the stool collection rod 2b will be in the air when the stool collection container 1 is placed sideways after being collected or stored with the drip cap 5 facing upward. It is also conceivable that the stability of the component to be measured in the stool is impaired due to exposure. For this reason, the shape of the inner plug 4 is preferably such that the volume of the storage solution storage portion is as small as possible.
Therefore, it is preferable that the outer shape of the inner plug 4 is substantially cylindrical, and the shape of the bottom surface 4a is a flat surface perpendicular to the longitudinal direction or a shape recessed from the periphery toward the central scraping portion 4b.

  Further, in the present embodiment, when the stool collection rod 2b from which the stool is collected is returned to the container, in order to facilitate the insertion of the stool collection rod 2b into the abrasion portion 4b, A stool collection rod guide portion including a plurality of inclined ribs 4c arranged radially is formed.

In the stool collection container 1, the inclined rib 4c is formed in a triangular shape having a side rising obliquely from the periphery of the scraping portion 4b, but if the stool collection rod 2b can be guided to the scraping portion 4b, The shape is not particularly limited.
In order to guide the stool collection rod 2b to the scraping portion 4b, it is only necessary to form a mortar around the scraping portion 4b. The quantity increases, and cooling takes time and the production speed is slowed down. Further, the shrinkage amount of the resin at the time of cooling becomes large, which is disadvantageous in terms of dimensional stability. However, a plurality of inclined ribs 4c are arranged in a radial manner, and the space between adjacent inclined ribs 4c is thinned to obtain a stool collection rod. Such inconvenience can be effectively avoided by forming the guide portion.

  The stool collection container 1 of the present embodiment is opened by suspending the dropping cap 5 after loosening the stool collected by the stool collection rod 2b in a preservation solution contained in the container body 3. Then, a squeezed container body 3, a suspension in which stool is suspended in a storage solution, is allowed to flow out from an extraction hole 3 a provided at the tip of the container body 3, and a filter attached to the dripping cap 5 6 and the filtrate is added dropwise for inspection.

  The filter 6 attached to the drip cap 5 can filter undigested solid matter that hinders inspection, and the material is not particularly limited as long as it is inert to the inspection target. Examples thereof include porous substances such as malt filters, filter papers, and resin sintered filters, and fibrous substances such as glass wool and absorbent cotton. It is preferable to use malt filters and resin sintered filters having a predetermined pore diameter. Such a filter may consist of one type or may be formed by stacking two or more types of filters.

  As a preservation solution for suspending the collected stool, any solution suitable for stool examination can be used. If necessary, a buffer, a stabilizer, a preservative, a dye, a disinfectant can be used. Additives such as odorants may be added. The amount of the storage solution stored in the container body is appropriately adjusted according to the stool suspension concentration required for the stool test. For example, when 5 mg of stool is collected, a dilution rate of 400 times can be obtained by setting the liquid volume to 2 ml.

  Furthermore, in this embodiment, as shown in FIG. 12, the flange part 3c is formed along the edge of the opening part of the base end side of the container main body 3. As shown in FIG. On the other hand, on the outer peripheral surface of the inner plug 4 shown in FIG. 6 described above, a projecting portion 4d extending in the circumferential direction at a position overlapping the flange portion 3c of the container main body 3 when the inner plug 4 is mounted in the container main body 3. Is formed.

  Further, in the present embodiment, the tip end portion of the inner plug 4 is formed with a scraping portion 4b in which the stool collection rod 2b adheres in a liquid-tight manner to remove excess feces, so that the inner plug 4 is made of a hard material. It is preferable to mold by using. On the other hand, the container body 3 can be molded using a soft material in consideration of squeeze properties, but in this case, the container body 3 and the inner plug 4 are formed of different materials that are difficult to weld, When fixing the inner plug 4 mounted in the container main body 3, the container main body 3 and the inner plug 4 are idle when the lid 2 is attached to and detached from the inner plug 4, or the lid 2 and the inner plug 4 are rotated together. It is desirable to prevent it. For this reason, in the present embodiment, as shown in the drawing, the flange portion 3c formed on the container body 3 side is formed with an engaging portion including a notch portion 3f and an overhang formed on the inner plug 4 side. The container body 3 when the lid 2 having the stool collection rod 2b is attached to and detached from the inner plug 4 is formed by forming a locking part made up of the protrusion 4e fitted to the notch 3f on the part 4d. The idling of the inner plug 4 or the co-rotation of the lid 2 and the inner plug 4 is prevented.

  In addition, as an engaging part formed in the flange part 3c by the side of the container main body 3 mentioned above, the recessed groove part, a through-hole, etc. other than the notch part 3f are mentioned, The inside plug 4 side according to these shapes is mentioned. What is necessary is just to select suitably the shape of the latching | locking part formed in the overhang | projection part 4d. Further, the engaging portion described above may be formed in the overhanging portion 4d on the inner plug 4 side, and the locking portion may be formed on the flange portion 3c on the container main body 3 side.

  Further, the flange portion 3c formed on the container body 3 side and the overhang portion 4d formed on the inner plug 4 side are formed in a rhombus shape shown in the figure or in order to prevent rolling when the stool collection container 1 is inspected. An elliptical shape, a track shape, or the like is preferably formed so that one of two orthogonal directions is long.

  As shown in FIGS. 13 and 14, a pair of blade portions 2 d that facilitate the rotation of the lid body 2 are formed symmetrically on the lid portion 2 a of the lid body 2, and the lower ends of the blade portions 2 d are formed. A pair of inclined grooves 2e are formed symmetrically by inflating the lower end side surface of the lid portion 2a of the lid portion 2 on the portion side into a hollow shape so that both sides on the upper side are inclined downward in a divergent shape. To do. On the other hand, as shown in FIGS. 6 and 13, a pair of inclined protrusions 4 f are formed on the inner circumference of the long diameter side of the overhanging portion 4 d of the inner plug 4. Form symmetrically. In this way, the lid 2 is placed by placing a finger on the blade portion 2d of the lid 2 by the detachment mechanism constituted by the sloped groove 2e of the lid 2 and the sloped protrusion 4f of the inner plug 4. By rotating, the lid body 2 can be easily detached from the inner plug 4.

  Note that the shape of both sides of the inclined groove portion 2e of the lid body 2 constituting the above-described detachment mechanism and the shape of both sides of the inclined projection portion 4f of the inner plug 4 make the rotation of the lid body 2 smooth. In order to eliminate the restriction of the rotation direction, it is preferable that the sides of the both sides and the sides of the inclined groove 2e and the inclined protrusion 4f have the same shape, and are linear or concave. It is preferable that the

  Furthermore, the inclined groove 2e of the lid 2 and the inclined protrusion 4f of the inner plug 4 do not need to be symmetrically formed as a pair, and any one of them may be formed. In addition, an inclined groove 2e formed on the lid 2 is formed on the side surface of the lower end of the lid 2a orthogonal to the blade 2d, and an inclined protrusion 4f formed on the inner plug 4 is formed on the short diameter side of the overhang 4d. The inclined groove portion 2e may be formed on the lower end side of the blade portion 2d of the lid portion 2a of the lid body 2, and the inclined projection portion 4f may be formed on the longer diameter side of the protruding portion 4d of the inner plug 4. Forming on the inner circumference is preferable from the viewpoint of facilitating the formation of each.

  In this case, when the lid body 2 is attached to the inner plug 4, the alignment of the inclined groove portion 2 e of the lid body 2 and the inclined protrusion portion 4 f of the inner plug 4 constituting the above-described detachment mechanism, and the lid The annular convex part 2f formed on the inner peripheral surface of the lid part 2a of the body 2 and the annular convex part 4g formed on the outer peripheral surface of the inner plug 4 are fitted. For this reason, as shown in FIG. 13, both sides are inclined downward in an inverted V shape with respect to the axial direction from the top side above the annular convex portion 4g of the inner plug 4, and preferably the lower end portion is in the axial direction. A pair of guide cams 4h hanging in parallel is formed symmetrically. On the other hand, as shown in FIG. 14, a pair of protrusions 2 h extending along the axial direction are formed symmetrically above the annular convex portion 2 f of the lid portion 2 a of the lid body 2. When the cam mechanism constituted by the guide cam 4h of the inner plug 4 and the protrusion 2h of the lid body 2 is rotated and pushed into the middle stopper 4 of the lid body 2 having the stool collection rod 2b, The protrusion 2h of the lid 2 is guided to the guide cam 4h of the inner plug 4. As a result, the lid body 2 can be easily and securely attached to the inner plug 4 in a state where the inclined groove portion 2e of the lid body 2 constituting the above-described detachment mechanism and the inclined protrusion portion 4f of the inner plug 4 are aligned. Can be fitted.

  Further, as described above, the flange portion 3c formed on the container body 3 side and the overhang portion 4d formed on the inner plug 4 side are formed so that one of the two directions perpendicular to each other is elongated, When the blade portion 2d is formed on the lid portion 2a, the guide cam 4h of the inner plug 4 of the cam mechanism described above is formed on the short diameter side of the protruding portion 4d of the inner plug 4, while the protrusion of the lid body 2 is formed. 2h is preferably formed at the same position as the blade portion 2d and the inclined groove portion 2e of the lid portion 2a. With such a configuration, sink marks at the time of molding of the lid portion 2a of the lid body 2 are prevented, and the blade portion 2d formed on the lid portion 2a is connected to the flange portion 3c formed on the container body 3. Positioned on the long diameter side of each of the overhang portions 4d formed in the inner plug 4.

  It should be noted that the protrusion 2h of the lid 2 and the guide cam 4h of the inner plug 4 do not have to be formed symmetrically, and either one may be formed. From the viewpoint of ease of mounting and fixing by fitting to the stopper 4 and stability, it is preferable that both are formed symmetrically as a pair. Further, the guide cam 4h of the inner plug 4 may be formed on the longer diameter side of the overhanging portion 4d, and the protrusion 2h of the lid 2 may be formed orthogonal to the blade portion 2d and the inclined groove portion 2e.

  As mentioned above, although this invention was shown and demonstrated preferable embodiment, this invention is not limited only to embodiment mentioned above, It cannot be overemphasized that various change implementation is possible in the range of this invention. .

  For example, in the embodiment described above, the wear plug 4b is formed inside the container body 3 by mounting the inner plug 4 with the wear cut 4b formed in the container body 3. 4 may be omitted, and the scraped portion 4 b may be formed directly inside the container body 3.

  As described above, the present invention can be used as a stool collection container for collecting stool during a stool inspection.
