Description

Technical Field

[0001] The present invention relates to the technical field of biological sample collection, and in particular to a biological sample collection card. Background Art

[0002] Currently, biological specimen collection primarily involves saliva or blood. The carriers used for both types of bodily fluids are typically FTA (FTA membrane or FTA card, a specialized filter paper), filter paper, or cotton swabs. Filter paper and cotton swabs are often wrapped in evidence bags to prevent biocontamination, while FTA cards are often covered with attached cardboard to prevent contamination, resulting in complex anti-contamination methods. Current carriers lack standard sizes and methods for monitoring sample collection quality. Due to varying levels of training among biological specimen collectors, the quality of collected biological specimens often varies. This lacks a high quality standard and makes it difficult to establish a high standard for biological specimen collection. Consequently, these carriers are unsuitable for automated extraction and testing, creating difficulties for automated testing. Current biological specimen testing involves manually punching holes in biological specimen carriers or cutting specimens with scissors for testing, which is inefficient. Furthermore, for large-scale biological specimen preparation, there is the risk of misidentification and mismatching of specimens (the accuracy of repetitive, high-volume work cannot rely on the meticulousness of test personnel). Summary of the Invention

[0003] To this end, the present invention provides a biological sample collection card that can standardize biological sample collection methods, monitor biological sample collection quality, standardize the biological sample collection process, provide basic conditions for the next step of automated extraction and testing of biological samples, and is suitable for biological sample collection and testing services, so as to solve the problems of complex anti-contamination methods, inconsistent collection quality, low degree of automation, and easy errors in the existing technology.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A biological sample collection card includes a body and a sliding cover. The body is provided with an FTA card. The sliding cover is sleeved on the circumference of the body and can slide along the length of the body. When the sliding cover slides to one end of the body, the sliding cover can cover the FTA card or expose the FTA card.

[0006] Furthermore, the upper surface of the FTA card is provided with a quality control line indentation line, the upper panel of the sliding cover is provided with a quality control line boundary line that can coincide with the quality control line indentation line, and the upper panel of the sliding cover is a transparent or translucent panel.

[0007] Furthermore, the upper and lower panels of the sliding cover are provided with split puncture holes, and the puncture holes are located within the boundary line of the quality control line.

[0008] Furthermore, the injection hole is a strip-shaped hole or a plurality of circular holes evenly distributed within the boundary line of the quality control line.

[0009] Furthermore, the body is also provided with an information area, and the FTA card and the information area are distributed along the length direction of the body. When the sliding cover slides to one end of the body, one of the FTA card and the information area is covered by the sliding cover, and the other of the FTA card or the information area is not covered by the sliding cover.

[0010] Furthermore, a barcode area is provided on one side surface of the information area, and a signature area or a fingerprint imprint area is provided on the other side surface of the information area.

[0011] Furthermore, a pair of symmetrical connecting clamps are provided at one end of the body, and a pair of symmetrical connecting slots are provided at the other end of the body. The connecting clamp of one biological sample collection card is connected to the connecting slot of another biological sample collection card, and the connecting clamp is rotatable in the connecting slot, thereby forming a sample chain or a collection card chain.

[0012] Furthermore, the connecting clamp is an elastic member.

[0013] Furthermore, a limiting column arranged along the width direction is respectively provided at both ends of the length direction of the main body, the length of the limiting column is greater than the width of the sliding cover, and the connecting clamp and the connecting slot are both connected to the main body through the limiting column.

[0014] Furthermore, a positioning protrusion is provided on the long side of the main body, and the positioning protrusion is located in the half area where the FTA card is located. A positioning groove adapted to the positioning protrusion is provided on the inner side of the sliding cover. When the sliding cover covers the FTA card, the positioning protrusion is stuck in the positioning groove to fix the position of the sliding cover.

[0015] The present invention has the following advantages:

[0016] During collection, the slide cover is slid aside to expose the FTA card. After collection is complete, the slide cover is slid back into position to cover the FTA card. The simple structure makes it easy and quick to use. Because the slide cover is positioned around the periphery of the body, it can cover both the upper and lower sides of the FTA card, providing a simple anti-fouling solution. Furthermore, the connecting head of the biological sample collection card engages with the connecting slot of another biological sample collection card, and the connecting head is rotatable within the connecting slot. Multiple biological sample collection cards can form a sample chain or collection card chain, providing the basic conditions for automated extraction and testing. The card can also be folded for storage, making it convenient for preserving biological samples. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0029] The following describes the implementation of the present invention using specific embodiments. Those skilled in the art will readily understand the other advantages and benefits of the present invention from the disclosure herein. Obviously, the embodiments described are only a portion of the present invention, not all of it. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are intended to fall within the scope of protection of the present invention.

[0030] The terms "upper", "lower", "left", "right", "middle", etc. used in this specification are only for the convenience of description and are not intended to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as within the scope of the present invention without substantially changing the technical content.

[0031] like Figure 1-9 As shown, the present invention provides a biological sample collection card that can standardize the biological sample collection method, monitor the quality of biological sample collection, standardize the biological sample collection process, provide basic conditions for the next step of automated extraction and testing of biological samples, and is suitable for biological sample collection and testing services. It solves the problems of complex anti-contamination methods, inconsistent collection quality, low degree of automation, and easy errors in the existing technology.

[0032] The biological sample collection card provided in this embodiment includes a body 1 and a slide cover 2. The body 1 is provided with an FTA card 3 (in this embodiment, the FTA card 3 refers to a special filter paper). The slide cover 2 is mounted around the periphery of the body 1 and can slide along the length of the body 1. When the slide cover 2 slides to one end of the body 1, it can cover or expose the FTA card 3. The anti-fouling design, in which the slide cover 2 slides on the body 1, simplifies the current common and complex biological sample anti-fouling mode. Sliding the slide cover 2 allows the biological sample to be switched between open and protected modes. The main body 1 is provided with a positioning protrusion 4 on its long side, located in the area where the FTA card 3 is located. A positioning groove 5 is provided on the inner side of the slider 2, which mates with the positioning protrusion 4. When the slider 2 covers the FTA card 3, the positioning protrusion 4 engages within the positioning groove 5. The design of the positioning protrusion 4 and the positioning groove 5 secures the slider 2 relative to the main body 1, preventing it from sliding away from the FTA card 3 and exposing the FTA card 3. The slider 2 can only slide open, revealing the FTA card 3, after applying a certain amount of force. Multiple protrusions 6 are provided on the side of the slider 2 to increase friction between the hand and the slider 2, allowing a greater force to release the positioning protrusion 4 from the positioning groove 5.

[0033] In this embodiment, the upper surface of the FTA card 3 is provided with a quality control line indentation 7, and the upper panel of the slide cover 2 is provided with a quality control line boundary line 8 that overlaps with the quality control line indentation 7. The upper panel of the slide cover 2 is transparent or translucent. Optionally, the entire slide cover 2 is made of translucent hard plastic. With a transparent or translucent upper panel, the quality control line indentation 7 on the FTA card 3 defines the collection coverage, and a clear quality control line boundary line 8 is provided at a corresponding position on the upper panel of the slide cover 2 to monitor the collection quality. This allows direct observation of the quality of the collected biological sample without opening the slide cover 2.

[0034] In this embodiment, a punch hole 9 is provided on the upper and lower panels of the sliding cover 2, located within the quality control line boundary 8. For sample punching inspection, the punching needle can pass directly through the upper and lower panels of the sliding cover 2 through the punch hole 9 to punch a hole in the FTA card 3 without sliding the sliding cover 2 open. Because the pinhole 9 is small, the FTA card 3 cannot be touched by human hands, thus preventing biological contamination. The design of the pinhole 9 also facilitates air circulation and keeps the sample dry. The pinhole 9 can be a single strip-shaped hole or multiple circular holes evenly distributed within the quality control line boundary 8.

[0035] In this embodiment, the body 1 also includes an information area. The FTA card 3 and the information area are arranged along the length of the body 1. When the slide cover 2 slides to one end of the body 1, one of the FTA card 3 and the information area is covered by the slide cover 2, while the other of the FTA card 3 and the information area is uncovered. A barcode area 10 is located on one side of the information area. Information such as the person's ID barcode, name, gender, ID number, collector, and collection time are integrated within this area. Barcode recognition facilitates automated sampling and testing. Alternatively, a barcode or QR code integrating information such as the ID barcode, name, gender, ID number, collector, and collection time can be affixed to the barcode area 10. A signature area or fingerprint area 11 is located on the other side of the information area. The person being sampled can sign or place a fingerprint to verify the accuracy of the sample at the source.

[0036] In this embodiment, one end of the body 1 is provided with a pair of symmetrical connecting clamps 12, which are elastic members. The other end of the body 1 is provided with a pair of symmetrical connecting slots 13. The connecting clamps 12 of one biological sample collection card are connected to the connecting slots 13 of another biological sample collection card. The connecting clamps can rotate within the connecting slots. Multiple biological sample collection cards can be connected end to end to form a sample chain or collection card chain. Figure 8 , which provides basic conditions for automated extraction and testing; when storing biological samples, it can also make adjacent biological sample collection cards staggered and folded, referring to Figure 9 This greatly reduces storage space and secures the position of biological sample collection cards, facilitating the storage of biological samples. Furthermore, this chain-connectable collection card design provides the fundamental prerequisite for automated extraction and testing of biological samples. A retaining post 14, extending along the width of the body 1, is located at each end of the body 1's length. The retaining post 14 is longer than the width of the slide 2. Both the connecting clip 12 and the connecting slot 13 are connected to the body 1 via the retaining posts 14, preventing the slide 2 from sliding off the edge of the body 1.

[0037] Although the present invention has been described in detail above using general descriptions and specific embodiments, it will be apparent to those skilled in the art that modifications and improvements may be made thereto. Therefore, such modifications and improvements, without departing from the spirit of the present invention, are intended to be within the scope of protection claimed herein.
