Abstract

Provided is a sample collection container in which a sample collection rod brought into contact with a sample can be smoothly inserted and scattering of infectious substances can be reduced. The sample collection rod is configured such that the cross section of the opening of the sample collection container into which the sample collection rod is inserted is not a transverse cross section, such as an oblique or stepped shape, perpendicular to the gap between the inner plugs of the sample collection container. Can be smoothly inserted into the sample collection container. Since the sample collection rod can be smoothly inserted into the sample collection container, scattering of infectious substances can be reduced and a large number of samples can be processed in a short time.

Description

  The present invention relates to a sample collection container that can be easily inserted when a sample is collected by a sample collection rod and inserted into the sample collection container.

  When a sample is introduced into a sample collection container including a sample collection rod, the sample collection rod is usually inserted after the sample collection rod has been removed from the sample collection container and brought into contact with the sample collection section of the sample collection rod. The sample collection rod is returned along the gap between the sample collection containers.

  At this time, if the area of the orthogonal cross section of the gap into which the sample collection rod is inserted is increased, the introduced sample or its diluted solution may leak from the sample collection container. Therefore, it must be minimized (Patent Document 1). As a result, it is difficult to insert the sample collection rod into the sample collection container.

  Here, if the sample to be collected is a sample that may contain an infectious substance such as stool, the sample collecting rod cannot be successfully inserted into the sample collecting container, and the risk of infection is increased by scattering the infectious substance. It is possible.

  Since the specimen collection container handles specimens that may contain infectious substances such as feces, the handling of these specimens must be handled carefully. On the other hand, in the field where a sample is introduced into a sample collection container, it is a fact that a large number of samples must be processed in a short time.

  Therefore, by using a sample collection container in which a sample collection rod can be easily inserted into the sample collection container, it becomes possible to reduce scattering of infectious substances and to process a large number of samples in a short time. Is expected to be.

  The sample collection container according to the present invention has a sample collection rod in the gap between the inner plugs in order to facilitate the insertion of the sample collection rod without changing the area of the orthogonal cross section of the gap between the inner plugs into which the sample collection rod is inserted. The ratio of the area of the cross section of the opening into which is inserted and the area of the orthogonal cross section of the gap between the inner plugs is made larger than 1, for example, an oblique or stepped shape.

  The sample collection container of the present invention has a cross section of the opening of the gap into which the sample collection rod is inserted, for example, by making it oblique or stepped, thereby increasing the cross-sectional area of the opening and opening the tip of the sample collection rod. There is an effect that the specimen collecting rod can be smoothly inserted in contact with the wall.

It is an external view of the sample collection container concerning one embodiment of the present invention. It is A-A 'sectional drawing of FIG. It is B-B 'sectional drawing of FIG. 1 is an external view of an inner plug according to an embodiment of the present invention. It is C-C 'sectional drawing of FIG. It is D-D 'sectional drawing of FIG.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

  A sample collection container 1 filled with a solution for diluting and suspending the sample shown in FIGS. 1, 2, and 3 includes a main body container 2, an inner plug 3, and a sample collection rod 4. Among these, the main body container 2 and the inner plug 3 are integrated in use.

  When collecting the sample, the sample collection rod 4 is removed from the sample collection container 1, and the sample collection portion 4a at the tip of the sample collection rod 4 is brought into contact with the sample to be collected, and then a sample of a sufficient amount is collected. Is inserted into the original sample collection container 1 along the gap 3a.

  As a result, the collected specimen is diluted and suspended with the solution previously filled in the specimen collection container 1 and can be used for clinical tests and the like.

  However, if the cross section of the opening into which the sample collection rod in the gap 3a of the inner plug 3 is inserted is an orthogonal cross section, the difference between the area of the cross section of the opening and the area of the orthogonal cross section of the sample collection section 4a is reduced. Therefore, it is difficult to collect the sample and insert the sample collection rod 4 into the sample collection container 1.

  Therefore, the cross section of the opening 3b of the inner plug 3 is not an orthogonal cross section of the gap 3a, that is, by making the cross section oblique, the area of the cross section is significantly larger than the area of the orthogonal cross section of the gap 3a of the inner plug 3 It becomes large and it becomes easy to insert the sample collection rod 4 into the sample collection container 1.

  Further, by making the section of the opening 3b of the inner plug 3 oblique, an opening wall 3c is formed on one side of the opening 3b of the inner plug 3, and when the sample collection rod 4 is inserted into the sample collection container 1, When the sample collection portion 4a comes into contact with the opening wall 3c on one side of the opening 3b of the inner plug 3, the sample collection rod 4 can be inserted more smoothly.

  In other words, the sample collection container 1 according to the present invention has an oblique section of the opening 3b of the inner plug 3 to collect the sample even when handling a sample that may contain an infectious substance such as feces. Since the rod 4 can be smoothly inserted into the sample collection container 1, it is expected that the scattering of infectious substances can be reduced and that a large number of samples can be processed in a short time.

  The present invention has been described with reference to one embodiment. However, the present invention is not limited to the above-described embodiment, and it is needless to say that various morphological variations are included within the scope of the present invention.

  For example, in the above-described embodiment, the opening 3b of the inner plug 3 is cut obliquely, but the embodiment in which the opening 3b of the inner plug 3 is cut stepwise is also included in the scope of the present invention. It is.

  When the sample collection container of the present invention is used, that is, when the sample is introduced into the sample collection container using the sample collection rod included in the sample collection container, the risk of scattering of the sample can be suppressed.
