Description

Technical Field

[0001] This utility model relates to the field of disease sampling technology, specifically a newborn genetic disease screening card. Background Technology

[0002] Newborn genetic screening plays an important role in preventing and reducing birth defects. In early screening, hospitals usually collect heel blood samples from newborns within a few days after birth and test them using Guthrie cards.

[0003] Currently, hospitals typically send all newborns' blood samples for testing at once after collection. The collected screening cards are usually placed directly on the card holder without additional protective measures to safeguard the sample carrier area. This makes the samples susceptible to contamination from droplets and dust during the process, increasing the probability of false positives and affecting the accuracy of the screening results. Screening cards with protective covers have emerged to cover the sample carrier area, aiming to reduce the risk of sample contamination. However, the existing protective covers require complete removal before use. During removal and re-applying, the cover can easily come into contact with contaminated surfaces, significantly increasing the risk of secondary contamination.

[0004] Therefore, it is particularly important to have a newborn genetic disease screening card that can reduce sample contamination while improving its drying efficiency to enhance the accuracy of screening results. Utility Model Content

[0005] The purpose of this invention is to overcome the aforementioned technical difficulties. This invention provides a newborn genetic disease screening card that can reduce sample contamination while improving its drying efficiency, thereby enhancing the accuracy of screening results.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a newborn genetic disease screening card, including a base card and a sample carrying area, wherein a folding area is provided between the base card and the sample carrying area, and a transparent baffle is adhered to the folding area. The transparent baffle includes an integrally formed straight part and a folded part, and the transparent baffle can be fastened to the surface of the sample carrying area at 90° in the forward direction or folded to the surface of the base card at 180° in the reverse direction. A sub-face sticker is provided on the front side of the straight part, and a mother face sticker is provided on the base card corresponding to the sub-face sticker. An elastic buffer block is provided on the back side of the straight part, and the elastic buffer block is located at the edge of the sample carrying area. An array of breathable mesh holes is provided in the area of ​​the straight part corresponding to the sample carrying area.

[0007] Furthermore, when the transparent baffle is reset and fastened, the buffer block and the folded part cooperate to form a ventilation channel that connects the ventilation mesh. The ventilation channel has a height of 1-3mm and is set at an angle of 5-15° with the horizontal plane.

[0008] Furthermore, the inner wall of the ventilation channel is provided with guide protrusions at intervals, the distance between adjacent protrusions is 3-5mm, and the height of the protrusions is 1 / 5-1 / 3 of the height of the ventilation channel.

[0009] Furthermore, the pore size of the breathable mesh is 0.2-0.5mm, the pore spacing is 1-2mm, and the mesh area accounts for 15-30% of the area of ​​the sample bearing area covered by the straight sheet.

[0010] Furthermore, the bonding area of ​​the mother side on the base card is set to avoid the base card barcode printing area.

[0011] Furthermore, the elastic buffer block is made of medical-grade silicone material, with a height of 1-3mm and a trapezoidal cross-section with an inclination angle of 30-45°.

[0012] Furthermore, a reinforcing rib is provided at the connection between the straight section and the folded section to increase the bending stability of the folded section, and the reinforcing rib is made of polycarbonate.

[0018] The technical solution of this utility model will be clearly and completely described below with reference to specific embodiments. The described embodiments are merely some, not all, of these embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0019] Example 1

[0020] like Figures 1-2 The present invention provides a newborn genetic disease screening card, comprising a base card 1 and a sample carrying area 2. The base card 1 is a flexible composite card containing a paper base layer and a waterproof coating layer, used to record basic information of the newborn. The sample carrying area 2 has five circular grooves with a diameter of 8.0 mm for collecting plantar blood samples from the newborn. A folding area 10 is provided between the base card 1 and the sample carrying area 2, and a transparent baffle 3 is adhered to the folding area 10. The transparent baffle 3 is made of PET material with a light transmittance of ≥92%, covering the base card surface. It can visually inspect the quality of blood spots while protecting the base card 1, preventing excessive contamination of the base card 1 area during operation; the transparent baffle 3 includes an integrally formed straight part 31 and a folded part 32. The transparent baffle 3 can be fastened to the surface of the sample carrying area 2 at a 90° angle or folded to the surface of the base card 1 at a 180° angle. That is, when fastened at a 90° angle, the straight part 31 completely covers the sample carrying area 2, and the breathable mesh 7 forms a micro-breathable barrier to block environmental pollutants; when folded at a 180° angle, the lettering and the mother label 5 are bonded and fixed, increasing the operating space.

[0021] The front of the straight section 31 is provided with a sub-adhesive 4, and the base card 1 is provided with a mother adhesive 5 corresponding to the sub-adhesive 4. The adhesion range of the mother adhesive 5 on the base card 1 avoids the barcode printing area of ​​the base card 1, which improves the convenience of operation and effectively forms a physical barrier, thereby improving its practical performance. The back of the straight section 31 is provided with an elastic buffer block 6. The elastic buffer block 6 is made of medical-grade silicone, with a height of 1-3mm and a trapezoidal cross-section with an inclination angle of 30-45°. The elastic buffer block 6 is located at the edge of the sample carrying area 2. The area of ​​the straight section 31 corresponding to the sample carrying area 2 is provided with an array of breathable mesh holes 7. The pore diameter of the breathable mesh holes 7 is 0.2-0.5mm, the pore spacing is 1-2mm, and the mesh area accounts for 15-30% of the area of ​​the sample carrying area 2 covered by the straight section 31. This ensures that the sample carrying area 2 is breathable while protecting it and reducing the contamination of the sample.

[0022] This invention, through the combination of a transparent baffle 3, an elastic buffer block 6, and a breathable mesh 7, can reduce sample contamination and improve the accuracy of screening results; furthermore, the combination of a ventilation channel 8 can accelerate air circulation and increase the drying rate of the sample carrying area 2; thus effectively solving the problems of easy contamination and low drying efficiency of existing genetic disease screening cards.

[0023] Example 2

[0024] Based on the above embodiments, this embodiment aims to improve the drying rate of the sample bearing area 2, such as... Figure 2As described in this application, when the transparent baffle 3 is reset and fastened, the elastic buffer block 6 and the folded part 32 cooperate to form a ventilation channel 8 that connects to the breathable mesh 7, forming an L-shaped channel to accelerate air circulation. The ventilation channel 8 has a height of 1-3mm and is set at an angle of 5-15° with the horizontal plane. The inner wall of the ventilation channel 8 is provided with guide protrusions at intervals, with an adjacent protrusion spacing of 3-5mm, arranged in a spiral with a pitch of 60°, and the height of the protrusions is 1 / 5-1 / 3 of the height of the ventilation channel 8. Furthermore, this application forms a three-dimensional channel by supporting the elastic buffer block 6, so that after the airflow enters from one side, the angle generates a pressure gradient, guiding the airflow upward. The height of the channel in this application is greater than the boundary layer thickness, forcibly penetrating the static air layer, and combined with the guide protrusions to create turbulence, breaking up the water vapor saturation zone, so as to accelerate the air circulation and improve the drying rate of the sample bearing area 2.

[0025] Example 3

[0026] Based on the above embodiments, in order to improve the stability of the ventilation channel 8 structure, this embodiment provides a reinforcing rib 9 at the connection between the straight section 31 and the folded section 32 to increase the bending stability of the folded section 32. The reinforcing rib 9 is made of polycarbonate. By setting the reinforcing rib 9, the stiffness of the ventilation channel 8 can be effectively prevented from changing suddenly due to external force, thereby improving its practical performance.

[0027] Before use, verify the information, then lift the transparent baffle 3 to 180°, and attach and fix the mother and daughter side panels 5. Next, collect blood samples. After blood sample collection, reset the transparent baffle 3. The setting of elastic buffer block 6 and breathable mesh 7, combined with the setting of ventilation channel 8, can accelerate air circulation and improve the drying rate of sample carrying area 2. Clinical tests show that the drying time is shortened from 3.5h to 1.8h, and the contamination rate is reduced by 15%, effectively solving the problems of easy contamination and low drying efficiency of existing genetic disease screening cards.
