Description

Stool collection kit

The present invention relates to a stool collection kit for collecting stool.

Conventionally, as a device for collecting stool as a biological sample for testing, a rod-shaped device (a stool collecting rod) has been used to prevent the hand from touching the stool during stool collection. The stool collection using a stool collection stick is performed by piercing the tip of the stool collection stick into the stool and pulling it out of the stool. If the tip is a spoon-shaped stool, the stool is collected by scooping. Usually, the stool collecting rod is then housed in a container with a lid and sent to an inspection agency for inspection.

To date, various stool collection rods have been developed, and for example, Patent Document 1 discloses a stool collection rod in which a stool collection rod and a container lid for housing the stool collection rod are integrally configured. It is disclosed. Specifically, the stool collecting rod extends from the lower portion of the lid that is flat and has a slip stopper formed of uneven portions on its surface, so that the stool collector can easily grasp it.

In addition to this, Patent Document 2 discloses a stool collection stick that is detachably attached to a lid of a container to be stored. The stool collection rod of Patent Document 2 uses the stool collection rod attached to the lid at the time of stool collection, and after the stool collection, the lid is attached to the container to accommodate the stool collection rod, and the lid is pushed to easily collect the valve. The rod can be dropped from the lid and dropped to the bottom of the container. With such a configuration, the stool sampling rod can be easily grasped during stool collection, and the stool sampling rod can be easily removed from the lid after stool collection.

The stool collecting rods described in Patent Documents 1 and 2 have a shape that is easy for the stool collector to grasp and handle, but since the stool collecting rod has a length that can be accommodated in a container, it is relatively short. It is necessary to bring the hand of the stool collector very close to the stool during stool, and the stool may adhere to the hand. Further, even if the stool does not adhere to the hand, the stool may give discomfort to the stool collector.

In order to solve such a problem, it is conceivable to make the stool stick longer to increase the distance between the stool and the hand of the stool collector at the time of stool collection. The container to be accommodated also needs to be large, which is not preferable from the viewpoint of handling the container, transportation cost of the container, and the like.

The present invention has been made in view of the above problems, and an object thereof is to reduce the discomfort given to a stool operator at the time of stool collection without lengthening the stool collection rod itself and to facilitate the handling. It is to provide a stool collection kit including a toilet stick.

In order to achieve the above-mentioned object, in the present invention, in a stool collection kit, an extension member comprising a long tubular portion having both ends open and a long extrusion portion having a diameter slidable in the tubular portion. Is configured to be attached to the stool collection stick.

Specifically, a stool collection kit according to the present invention includes a shaft portion, a distal end portion having a stool collection portion arranged on one end side of the shaft portion for collecting stool, and arranged on the other end side of the shaft portion. Stool collecting rod including a proximal end portion, an elongated tubular portion having an inner diameter at which the proximal end portion of the stool sampling rod can fit, and slidable inside the tubular portion An extension member including a long-sized extruded portion having a diameter, and in a state in which the base end portion of the stool sampling rod is fitted to one end side of the tubular portion, the extruded portion is different from the tubular portion. It is configured such that the proximal end portion can be pushed out of the tubular portion and pushed away from the tubular portion by being pushed into the one end side from the state protruding from the end side, and the fecal sampling rod can be detached from the tubular portion. .

According to the stool collection kit of the present invention, the stool collection rod can be attached to the elongated extension member by fitting the base end of the stool collection rod into the tubular portion of the extension member. Since the length can be substantially extended, the distance between the stool's hand and the stool at the time of stool collection can be increased. Further, in the stool collection kit according to the present invention, in a state where the proximal end portion of the stool collection rod is fitted to one end side of the tubular portion, the pushing portion is pushed from the other end side of the tubular portion to the one end side. By doing so, the base end can be pushed out of the tubular portion, so that the stool collecting rod can be easily removed from the extension member without touching the stool collecting rod after collecting stool. As a result, it is possible to prevent the stool from adhering to the hand of the stool collector, and to prevent the stool collector from feeling uncomfortable. Further, there is no need to enlarge the container for accommodating the stool collecting rod.

In the fecal sampling kit according to the present invention, it is preferable that the extruding portion has a length equal to or longer than the length of the tubular portion.

With this arrangement, when the proximal end portion of the stool collecting rod is fitted to the one end side of the tubular portion, the pushing portion is pushed into the one end side from the state of protruding from the other end side of the tubular portion. The toilet stick can be detached from the tubular portion.

In the fecal sampling kit according to the present invention, it is preferable that the extension member is made of a water-soluble material.

In this way, the extension member can be flushed into the toilet after removing the fecal sampling rod from the extension member after collecting stool, so that the extension member can be easily disposed of.

It is preferable that the stool collection kit according to the present invention further includes a container with a lid having a size capable of containing the stool collection rod but not the extension member.

By doing this, the size of the container for accommodating the stool collection rod can be made as small as possible, so that the transportation cost can be reduced.

In the stool collection kit according to the present invention, it is preferable that the base end portion of the stool collection rod is flat.

If you do this, the stool collection stick will be easier to grasp and the handling will be improved.

In this case, it is preferable that the base end portion of the fecal sampling rod has a substantially rectangular surface shape, and both widthwise ends of the base end side are chamfered.

By doing this, the base end of the fecal sampling stick becomes tapered toward the base end side, so when the base end is fitted into the tubular part, it is easy to insert the base end into the tubular part. You can
