The Manufacturing Process of Dried Blood Spot Collection Cards

The manufacturing process of Huachen Yang dried blood spot collection cards involves multiple stages to ensure product quality and effectiveness. The following outlines the main steps in the production of dried blood spot collection cards.

Material Selection

The first step in making dried blood spot collection cards is material selection. Typically, biocompatible, non-toxic materials such as polyester fiber or other synthetic fibers are chosen. These materials not only exhibit excellent absorbency but also effectively fix blood components during the drying process. Additionally, strict quality control is applied to ensure that the materials used meet medical device standards.

Card Design

The design of the dried blood spot collection card is crucial. The card is usually divided into multiple absorbent areas to facilitate blood sample collection from different spots. The design must consider blood flow and fixation to ensure that samples are evenly distributed across the absorbent areas, preventing uneven samples from affecting subsequent testing.

Manufacturing Process

The manufacturing process for dried blood spot collection cards generally includes the following steps:

1. Material Cutting: Based on design specifications, selected biocompatible materials are cut into appropriate sizes and shapes. Each absorbent area’s size and position are carefully calculated to ensure optimal sample collection efficiency.
2. Surface Treatment: To enhance blood absorption efficiency, the card’s surface undergoes special treatment. This process may involve applying agents to improve the material’s hydrophilicity and absorptive capacity.
3. Quality Testing: After production, every batch of dried blood spot collection cards undergoes rigorous quality testing. This includes visual inspections, absorbency performance tests, and biocompatibility tests to ensure that each product meets medical standards.
4. Packaging and Labeling: Finally, qualified dried blood spot collection cards are packaged and labeled. The labels usually include usage instructions and precautions to ensure that users can utilize the cards correctly.

Storage and Transport

After manufacturing, the storage and transport of dried blood spot collection cards must adhere to specific regulations. Typically, the cards are stored in a cool, dry environment, avoiding direct sunlight and high temperatures. During transport, moisture-proof and pressure-proof packaging is required to ensure the integrity of the cards.

In summary, the manufacturing process of Huachen Yang dried blood spot collection cards focuses not only on material selection and card design but also emphasizes quality control and user experience. Through a scientific manufacturing process, each collection card is ensured to efficiently and accurately collect blood samples.
