Description

  The present invention relates to a stool collection apparatus for collecting a stool sample for performing a stool inspection or the like.

  Conventionally, various types of stool collection instruments are known. For example, it is composed of a test container having a test tube and containing a reaction reagent, and a reagent container having a tube shape and a sealing material adhered to the upper and lower openings and enclosing the reagent therein, and the upper part of the measurement container. There has been proposed an invention of a specimen testing instrument characterized by fitting a reagent container into an opening (Patent Document 1). In addition, a sampling part support stick part provided with a cotton ball at the tip, a cap that supports the proximal end side of the sampling part support stick part, and a bottomed and cylindrical shape, the tip of the mouth is closed by the cap Has been proposed (Patent Document 2), which is a specimen collection instrument set having a container to be stored and a storage medium housed in the bottom of the container. Further, a container main body for storing a liquid for suspending feces, a lid body connected to one end of the container main body, a separating means for separating an internal space between the container main body and the lid body, and formed in the separating means A stool collection rod inserted into the through hole, the stool collection rod comprising a stool collection rod body and a number of hairs provided at or near the tip of the stool collection rod body The invention of a stool collection tool characterized by having a stool collection part having a stool has been proposed (Patent Document 3).

  However, the conventional stool collection device has a cotton ball or hair at the tip, but when using such a cotton ball or hair, it can be suitably collected if the stool is a watery stool. However, if the stool is a solid stool, only a small amount can be collected, which tends to cause inconvenience in the examination. However, if the tip has a shape suitable for collecting solid stool, there is a problem that watery stool cannot be collected more effectively.

  Thus, in the conventional stool collection apparatus, there was no thing which can be collected stool suitably for both watery stool and solid stool. In particular, in stool inspection, it is preferable to collect a certain amount of sample as much as possible. Therefore, a stool collection apparatus that can collect a predetermined amount of stool regardless of the state of the stool has been desired.

  In addition, there is a risk that stool will adhere to the hand when taking a stool, especially if the presence of an infectious agent in the stool is suspected. There is. For this reason, there has been a long-awaited need for a stool collection device that has as little risk as possible.

  The present invention has been made in view of the above problems, and in a test using stool as a specimen, a predetermined amount of stool can be easily collected regardless of whether it is a solid stool or a watery stool. An object of the present invention is to provide a stool collection device that can be used and that is less likely to get dirty.

  The present invention for solving the above problems is provided with a long stick portion having a length of 13 cm or more, a cotton ball for stool collection provided at one end of the stick portion, and the other end of the stick portion. A stool collection device, comprising a stool collection spoon.

  According to the stool collection apparatus of the present invention, it is possible to easily collect a predetermined amount of stool regardless of whether it is a solid stool or a watery stool, and it is possible to collect it in a situation where there is little possibility of getting a hand dirty. Therefore, it is possible to reduce the burden on the person in charge of the inspection who performs the inspection using the stool as a specimen. Especially when targeting patients suffering from gastroenteritis, etc., the state of the stool varies from patient to patient, and it is also possible that the stool contains infectious bacteria. The stool collection apparatus of the present invention that can easily collect a predetermined amount of stool and has a low risk of stool adhering to the hand is suitable.

  The stool collection apparatus of the present invention has a long stick part. As the material of the stick portion, for example, paper, plastic, wood or the like can be used. The thickness of the stick portion may be any thickness as long as it is easy to hold. Further, the thickness of the stick portion does not need to be constant from end to end, and only the central portion of the stick portion may be formed thicker than both end portions. As the cross-sectional shape of the stick portion, a free shape such as a circle, an ellipse, a square, a triangle, and other polygons can be selected, but a shape that is easy to hold is preferable.

  The length of the stick part needs to be 13 cm or more. This length is the length of a long portion that can be grasped by hand without including the length of a cotton ball or spoon described later.

  If the length of the stick portion is less than 13 cm, it becomes easy to adhere to the hand when taking a stool, and it is difficult to enjoy the effects of the present invention. Therefore, the length of the stick portion needs to be 13 cm or more. In addition, if you have such a long stick part, when you transfer the collected stool to the test tube, the stick part with a sufficient length will protrude from the test tube with the stick part inserted into the test tube. Thus, the examiner can move the stool to the test tube in a situation where the possibility of touching the test tube is low.

In addition, since a handling will become inconvenient if a stick part is too long, it is preferable that the length of a stick part is 20 cm or less.
The present invention is characterized in that a cotton ball for stool collection is provided at one end of such a stick portion. The material of the cotton ball may be any fiber as long as it is a fiber and may be any synthetic fiber such as rayon or the like, but “cotton” is the most desirable in view of cost and availability.

  The shape and size of the cotton ball is preferably an ellipse having a diameter of 6 mm and a length of 10 mm, but it may be circular, flat, spindle-shaped, dish-shaped, spoon-shaped, with a sharp tip. Appropriate shapes and sizes such as a shape, a shape wound in a spherical shape, and a stepped shape can be selected. It is preferable to basically adjust the shape and size of the cotton ball according to the amount of stool to be collected. That is, the amount of absorption can be adjusted to some extent by adjusting the amount of fiber used. Such a cotton ball is preferably used mainly when the state of the stool is watery stool.

  The present invention is also characterized in that a stool collection spoon is provided at the other end of the stick portion. The spoon is preferably used particularly when the stool is solid stool. Of course, the size and shape of the spoon are also selected depending on the amount of stool to be collected. The shape of the spoon usually has a “recess” and the stool is acquired by the “recess”, and any shape can be used as long as this purpose is achieved. That is, it is possible to select various shapes such as a bead shape, an elliptical hollow shape, a polygonal hollow shape, etc., which are only the shape of a normal spoon. In addition, you may form such a spoon integrally with a stick part.

  The stool collection apparatus of the present invention as described above collects stool using a cotton ball at one end if the stool is watery, and uses the other spoon if the stool is solid stool. Take a flight. Thus, the stool collection apparatus of this invention can respond | correspond to various stool with one. Moreover, it is always possible to collect an almost constant amount of stool. Moreover, since the stick part has a length of 13 cm or more, it is effectively prevented that the hand comes into contact with the stool during stool collection, and there is a sense of security for the user.
