Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of gene testing consumables, in particular to a DNA blood sample storage card. Background Art
[0002] DNA blood sample storage cards, also known as blood collection cards, have a wide range of applications, primarily for the collection, storage, and transportation of DNA. In forensic medicine, their main uses include: (1) extraction, database construction, and storage of DNA blood samples from forensic suspects; (2) extraction and storage of DNA blood samples for paternity testing; and (3) extraction of DNA specimens from crime scenes.
[0003] A blood collection card typically consists of a blood collection card and filter paper. The filter paper is typically a FTA card, specifically designed to hold blood samples. Made of a special material, the FTA card prevents deterioration and helps preserve DNA for up to 30 years. For DNA testing, a special punch pen is used to punch a hole in the bloodstain on the STA card, remove a small piece, and place it in a reagent for processing before proceeding to the next step of DNA testing.
[0004] In forensic work, DNA samples are generally required to be stored for at least 30 years to facilitate subsequent sampling and comparison when needed. Blood collection filter paper, due to its special material, is typically bonded to the rest of the card. This can easily cause it to fall out of the blood collection card during long-term storage. When multiple sets of blood collection cards are stored together, the filter paper can fall out and become mixed, potentially affecting subsequent storage and resolution.
[0005] Patent CN214434210U discloses a blood collection card comprising a card body and blood collection filter paper. The card body includes a front cover and a back cover, separated by a fold line; the blood collection filter paper is connected at the fold line. The blood collection filter paper is connected to the fold line on the inner surface of the front and back covers. When the front and back covers are opened, the blood collection filter paper is exposed on the outermost surface, facilitating blood collection. When the front and back covers are closed, the front and back covers protect the blood collection filter paper inside, preventing contamination caused by improper handling or friction with other objects. In addition, by closing the front and back covers at a certain angle, the front and back covers can serve as a drying rack for the blood collection filter paper, facilitating the drying of the blood collection card. Since only the front and back covers of this blood collection card can be sealed, when the blood collection card is turned over after long-term storage, the blood collection filter paper may fall out. Utility Model Content
[0006] The purpose of the utility model is to solve the problems in the background technology and to propose a DNA blood sample storage card.
[0007] In order to achieve the above purpose, the present invention adopts the following technical solutions:
[0008] A DNA blood sample storage card includes a card body, wherein the card body includes:
[0009] first back cover, second back cover and cover;
[0010] The first back cover and the second back cover are separated by a first fold line;
[0011] The cover and the first back cover are separated by a second fold line;
[0012] The card body is provided with a clamping portion;
[0013] The blood collection filter paper is fixedly connected to the second back cover.
[0014] Preferably, the locking portion includes a first locking strip and a second locking strip, the first locking strip is fixedly connected to the cover, a first locking hole is provided on the second bottom cover, and the first locking strip can pass through the first locking hole, the second locking strip is fixedly connected to the second bottom cover, a second locking hole is provided on the cover, and one end of the second locking strip can pass through the second locking hole.
[0015] Furthermore, the locking portion further includes a symmetrically arranged third locking strip, a third locking hole is opened on the second bottom cover, and one end of the third locking strip can pass through the third locking hole.
[0016] Preferably, the blood sampling filter paper is fixed to the second back cover by adhesive.
[0017] Furthermore, the first back cover is provided with ventilation holes, with multiple groups of ventilation holes evenly distributed on the first back cover. Since the blood sample needs to be dried as soon as possible after blood collection to prevent mold and affect its application, the DNA blood sample storage card of this solution adopts a ventilation setting to facilitate the drying of the blood collection filter paper.
[0018] Furthermore, the length of the vent hole is smaller than the diameter of the blood sampling filter paper. The vent hole length smaller than the diameter of the blood sampling filter paper can prevent the blood sampling filter paper from falling out of the DNA blood sample storage card body through the vent hole.
[0019] Preferably, an information recording area is provided on the second back cover to facilitate recording of blood sample information. Compared with the prior art, the present invention provides a DNA blood sample storage card with the following beneficial effects:
[0020] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can block the sliding path of the blood collection filter paper in multiple directions by inserting multiple groups of card strips into the card holes in the device, thereby effectively preventing the blood collection filter paper from sliding out of the card body due to its own sliding during the storage process, thereby solving the problem in the existing technology that multiple blood collection filter papers are easily mixed together and difficult to distinguish when they slide out.

Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0025] Example:
[0026] Reference Figure 1-Figure 2 , a DNA blood sample storage card, comprising a card body 1, the card body 1 comprising:
[0027] A first back cover 102, a second back cover 103 and a cover 101;
[0028] The first back cover 102 and the second back cover 103 are separated by a first fold line 3;
[0029] The cover 101 and the first bottom cover 102 are separated by a second fold line 4;
[0030] The card body 1 is provided with a snap-fit portion;
[0031] The blood collection filter paper 2 is fixedly connected to the second back cover 103 .
[0032] The locking portion includes a first locking strip 1011 and a second locking strip 1032. The first locking strip 1011 is fixedly connected to the cover 101. A first locking hole 1033 is provided on the second bottom cover 103. The first locking strip 1011 can pass through the first locking hole 1033.

One end of the second locking strip 1032 can pass through the second locking hole 1013.
[0033] Reference Figure 1-Figure 2After the blood collection is completed, the second back cover 103 can be pressed along the first fold line 3 so that the second back cover 103 and the first back cover 102 are in contact with each other, and then the cover 101 can be pressed along the second fold line 4 so that the cover 101 and the second back cover 103 are in contact with each other, thereby pressing the cover 101 against the blood collection filter paper 2.
[0034] Reference Figure 1 During the closing process of the cover 101, the staff can manually insert the second card strip 1032 into the second card hole 1013, and then insert the first card strip 1011 into the first card hole 1033;
[0035] The first clamping strip 1011 and the second clamping strip 1032 provided in the device are respectively clamped into the first clamping hole 1033 and the second clamping hole 1013, thereby effectively preventing the blood sampling filter paper 2 from sliding horizontally and sliding out of the card body 1.
[0036] The engaging portion further includes a symmetrically arranged third engaging strip 1012 . A third engaging hole 1031 is defined on the second bottom cover 103 , and one end of the third engaging strip 1012 can pass through the third engaging hole 1031 .
[0037] Reference Figure 1 Before the first clamping strip 1011 is clamped into the first clamping hole 1033, the staff can clamp the two sets of third clamping strips 1012 into the third clamping holes 1031 respectively;
[0038] The two groups of third clamping strips 1012 provided in the device are clamped into the third clamping holes 1031 , thereby effectively preventing the blood sampling filter paper 2 from sliding longitudinally and sliding out of the card body 1 .
[0039] By inserting multiple sets of card strips into the card holes, the sliding path of the blood collection filter paper 2 can be closed in multiple directions, thereby effectively preventing the blood collection filter paper 2 from sliding out of the card body 1 due to its own sliding during the storage process, thereby solving the problem in the prior art that multiple blood collection filter papers 2 are easily mixed together and difficult to distinguish.
