Disposable vacuum blood collection is a medical device widely used in modern medical diagnosis, with the following significant features and advantages:
Trait
Vacuum seal design
The inside of the sampling vessel is vacuum-vacuum-filled, which automatically draws a precise amount of blood sample without the need for additional straws or syringes. This design not only improves the efficiency of blood collection, but also minimizes the risk of sample contamination.
Sterility and single use
Blood vessels are packed aseptically, and the material is usually medical grade plastic or glass, which has the characteristics of high temperature resistance, corrosion resistance and non-toxic. The single-use design effectively avoids cross-infection and ensures the safety of both doctors and patients.
Color coding system
Different colors of the cap correspond to different additives and detection purposes. For example, the purple cap is an EDTA anticoagulant tube for whole blood testing; The blue cap is a sodium citrate anticoagulant tube used for testing coagulation function. This color-coded system allows healthcare professionals to quickly identify and select the right vessel.
Multiple additives
Anticoagulants, clot activators or separation adhesives can be added to the blood collection tube according to requirements to meet different detection needs. For example, heparin anticoagulant tubes are used for plasma biochemical experiments, while collection vessels containing fluoride are used for blood glucose measurements.
Accurate blood collection
The vacuum mechanism ensures that the amount of blood collected each time is accurate, avoiding detection errors caused by insufficient or excessive sample size. This accuracy is essential for obtaining reliable test results.
Disposable vacuum blood vessel collection is mainly used to collect human venous blood samples, and is widely used in clinical examination and diagnosis. It works by drawing blood directly from the vein into the tube using a preset vacuum negative pressure in the tube, while stabilizing the sample by adding specific chemicals.
According to different testing needs, blood vessels are divided into various types:
Whole blood vessels: used for hematological testing.
Blood plasma collection vessels: for biochemical and immunoassay.
Blood serum collection vessel: used for testing coagulation function.
High safety: Single-use and aseptic design effectively reduces the risk of cross-infection.
Convenient operation: The vacuum blood collection process is fast and efficient, reducing the discomfort of patients.
Accurate detection: The use of vacuum seals and additives ensures the stability of samples and the reliability of test results.
Standardized processes: Color-coded systems and preset vacuum designs simplify operating processes and reduce human error.
In short, disposable vacuum blood collection has become an indispensable tool in modern medical diagnosis due to its high efficiency, safety and accuracy
