Glossary Entry: Blood Collection System


Definition: A blood collection system is a medical device used to collect blood samples from patients for diagnostic testing or medical procedures. It includes components such as needles, collection tubes, and vacuum containers, and is crucial for obtaining accurate and reliable blood samples.

Detailed Description

Types and Variations

Variations: Blood collection systems come in various sizes and configurations to accommodate different types of blood collection, including venous blood collection, capillary blood collection, and arterial blood gas sampling. Each variation is designed for specific applications and may include different needle gauges and tube sizes.


Common Uses: Blood collection systems are commonly used in clinical settings to obtain blood samples for laboratory testing, transfusions, and diagnostic procedures such as blood gas analysis, glucose testing, and coagulation studies.

Insertion and Placement

Procedure: The insertion and placement of a blood collection system involve proper venipuncture techniques or skin puncture for capillary blood collection. Special considerations may be necessary for patients with fragile veins, and clinicians should be trained in the use of the Seldinger technique for arterial blood gas sampling.

Clinical Considerations

Potential Complications

Risks: Potential complications associated with blood collection systems include bruising, hematoma formation, infection at the puncture site, and nerve damage. Proper technique and adherence to aseptic procedures can minimize these risks.

Care and Maintenance

Maintenance Requirements: Blood collection systems should be handled with care to prevent damage to needles and tubes. Proper disposal of used needles and tubes is essential to prevent cross-contamination and exposure to bloodborne pathogens.

Additional Information

Related Devices

Associated Terms: Related devices include needle holders, blood collection trays, and tourniquets, which are often used in conjunction with blood collection systems to facilitate the collection process.

Innovations and Advancements

Recent Developments: Recent advancements in blood collection systems focus on improving safety features, such as needlestick prevention mechanisms and barcode identification for efficient specimen tracking and labeling.

Regulatory and Safety Notes

Regulations: Blood collection systems must comply with regulatory standards for medical devices to ensure safety and performance. Proper training and certification for healthcare professionals using these systems are also essential to maintain quality and patient safety.
