ASTM A269 TP304 High Precision Stainless Steel Capillary Tube， Hypodermic Tubing Medical Device
High Precision Stainless Steel Capillary Tube， also known as hypodermic tubing， refers to a type of small-diameter， thin-walled tubing often used for precise and accurate fluid delivery， sampling， and measurement. It is manufactured with tight tolerances to ensure precise internal and external dimensions.
Capillary tubes find wide applications in the medical field due to their small diameter， precision， and corrosion-resistant properties. Here are some ways in which capillary tubes are used in medical usage:
Blood Collection: Capillary tubes are commonly used for micro-hematocrit centrifugation， a technique used to determine the ratio of red blood cells to total blood volume. A capillary tube is filled with blood obtained from a finger prick， and after centrifugation， the hematocrit level can be measured.
Blood Gas Analysis: Capillary tubes are used for collecting small samples of arterial blood for blood gas analysis， which assesses oxygen， carbon dioxide， pH， and other parameters. The capillary tube is inserted into an arterial puncture site， and blood is withdrawn for analysis.
Microfluidics: Capillary tubes play a crucial role in microfluidic systems used in medical diagnostics. They are used for precise fluid delivery， mixing， and separation of small liquid samples for applications like immunoassays， DNA analysis， and point-of-care testing.
Drug Delivery: Capillary tubes are used in drug delivery systems， such as insulin pens or insulin pumps， where precise and controlled amounts of medication need to be delivered subcutaneously. The small diameter of the capillary tube allows for accurate dosage control.
Laboratory Testing: Capillary tubes are utilized in various laboratory procedures， including microsampling， microextraction， and microinjection. They enable the collection and handling of small volumes of biological samples for testing purposes.
Endoscopy: Capillary tubes， specifically those with imaging capabilities， are integrated into endoscopes used for medical imaging and diagnostics. These tubes allow for the passage of light or images to visualize internal body structures.
Biopsy and Tissue Sampling: Capillary tubes are employed to aspirate or collect minute tissue samples during biopsies or less invasive procedures like fine-needle aspiration. The small size of the capillary tube minimizes trauma and allows for targeted sampling.
