Description

  The present invention relates to the structure of a biological sample collection kit for collecting blood, semen, body fluid, and other biological samples. Collecting a biological sample in this specification does not directly collect a biological sample from a human body, but collects a biological sample from a biological sample (hereinafter referred to as a “biological sample mark”) left in an accident scene, crime scene, or the like. To do.

  For example, when collecting and storing blood from blood stains left in an accident scene, crime scene, etc., sterilized water (purified water) is added to the dried blood stains to dissolve the blood stains, and the resulting blood is gauze. The liquid is absorbed into a sample bottle and stored in a labeled sample bottle or a plastic bag. Moreover, JP, 2007-139599, A (patent documents 1) is mentioned as a kit which collects blood.

JP 2007-139599 A

  The collected blood is used for analysis such as DNA identification. In order to accurately analyze blood, the work is complicated because gloves, tweezers, and the like are required when collecting blood.

  The specific work is as follows. First, items of “sterile water”, “gauze”, “filter paper”, “tweezers”, “specimen storage container”, “nylon bag”, and “sealing seal” are prepared. These items are individually packaged. These items are opened individually when used.

  First, “gauze” is immersed in “sterile water” as necessary. If necessary, use “filter paper” to remove excess water soaked in “gauze”. When the blood stain is dry and fixed, the blood stain is dissolved using “sterile water”.

  Blood is collected using “Gauze”. Use “tweezers” to handle “gauze”. The “gauze” from which blood has been collected is stored in a “sample storage container”. The “sample storage container” and the bag used for individual packaging are stored in the “nylon bag”. "Nylon bag" is protected by "sealing seal". Fill out the necessary information on the “sealing seal”. Thereafter, the blood is carried to a place where blood analysis is performed (for example, a forensic research institute).

  As described above, the work of collecting blood is complicated. It is also necessary to bring many necessary items to the blood collection site. Also, the individual packaging of each item will eventually be discarded.

  The same problem arises when not only the collection of blood but also a biological sample is collected from a biological sample trace.

  Accordingly, the present invention has been made in view of the above problems, and a biological sample collection kit that eliminates complicated steps when collecting biological samples from biological sample traces and can easily collect biological samples. It is to provide.

  In the biological sample collection kit based on this invention, the biological sample collection kit collects the biological sample from the biological sample trace, the biological sample collection piece to which the biological sample is attached, sterilized water, desiccant, and main body And a lid member attached to the main body.

  The main body portion has a first opening that communicates with the outside, a biological sample collection piece accommodation region that accommodates the biological sample collection piece inside, and a second opening that communicates with the outside, and the biological sample collection piece accommodation region The sterilized water storage area for storing the sterilized water therein and the biological sample collection piece storage area are provided in isolation and provided in the sterilized water storage area for storing the desiccant therein. And a desiccant containing area.

  The lid member includes a first lid member that is mounted so as to close the first opening, and a second lid member that is mounted so as to close the second opening.

  The first lid member includes a rod-like member to which the biological sample collection piece is attached at a distal end portion and is inserted into the biological sample collection piece accommodation region.

  In another aspect, the main body includes a first container and a second container that is detachably provided to the first container, and the first container has the first opening. The biological sample collection piece containing area and the desiccant containing area communicating with the biological sample collection piece containing area are provided, and the second container portion has the second opening and contains the sterilized water. A water storage area is provided, the first lid member is a cap member including a female screw portion that is screwed into a male screw portion provided around the first opening, and the second lid member is configured to store the sterilized water. The seal member is affixed to the second container portion so as to close the second opening in a state where the sterilized water is contained in the region.

  In another form, the first container part includes a cover that allows the desiccant-containing area to be opened and closed.

  In another embodiment, the paper further includes a filter paper, and the filter paper is disposed in a region sandwiched between the first container portion and the second container portion.
