RDVT-01 Drawing Volume Tester

Introduction to the Vacutainer Blood Draw Volume Tester

The Vacutainer Blood Draw Volume Tester is an advanced testing instrument designed to measure the volume of blood drawn into a Vacutainer tube. In medical diagnostics, accurate blood collection is crucial for reliable test results. The Vacutainer tube is a specialized container, typically made of glass or plastic, that utilizes a vacuum-sealed rubber stopper to pull a specific volume of liquid into the tube. This precise blood collection process is essential in laboratories, hospitals, and clinical trials to ensure the accuracy of diagnostic tests.

The Vacutainer Blood Draw Volume Tester plays a critical role in confirming that each Vacutainer tube collects the proper blood volume, supporting the integrity and reliability of medical tests.

Vacutainer Tube Overview

A Vacutainer tube is a specially designed container used to collect blood or other liquid samples. It features:

• Materials: Constructed from glass or plastic with a rubber stopper that forms an airtight seal.
• Vacuum Function: The vacuum inside the tube helps to draw blood into the container when the needle punctures the rubber stopper.
• Additives: Different colored stoppers indicate specific additives inside the tube, which preserve or stabilize the blood for various laboratory tests.
• Safety and Labeling: The tubes often include safety features to prevent contamination, and customizable labeling options ensure efficient specimen tracking and identification.

Test Methodology

The test process for measuring the blood draw volume in a Vacutainer tube is straightforward and involves the following steps:

1. Inserting the Vacutainer Tube:
   • Insert the pre-evacuated Vacutainer tube into the puncture site of the testing system. The internal pressure of the system is adjusted to match the pressure inside the tube to ensure accurate volume measurement.
2. Adjusting Pressure According to Altitude:
   • The internal system pressure is adjusted based on the altitude of the testing region (since atmospheric pressure changes with altitude). This adjustment ensures consistent performance in varying environmental conditions.
3. Measuring the Blood Drawn Volume:
   • The vacuum draws blood into the tube, and the weight of the tube is measured before and after the test. The difference in weight is used to calculate the exact volume of blood drawn into the Vacutainer tube.

Technical Features

• PLC Control & HMI Touch Screen:
  The Vacutainer Blood Draw Volume Tester is controlled by a Programmable Logic Controller (PLC), ensuring stable industrial-level performance. The Human-Machine Interface (HMI) touch screen allows for easy operation and intuitive control, making it user-friendly and efficient for operators.
• Constant Pressure Control:
  The tester maintains a consistent pressure within the system during testing, automatically adjusting to account for variations in the liquid level. This ensures that each blood draw is measured with high precision, without fluctuation in results.
• Embedded Vacuum Pump:
  The system is equipped with an integrated vacuum pump, saving space and reducing operational costs compared to using external pumps. The embedded design ensures optimal space efficiency while maintaining high performance.

Main Parameters and Specifications

• Vacuum Degree: 0~-40 KPa (equivalent to an altitude of 3600 meters)
  • This range ensures the system can simulate real-world conditions, from sea level to high altitudes, providing accurate blood volume measurements regardless of location.
• Control System:
  • PLC and Human-Machine Interface (HMI) for smooth, precise control of all testing parameters.
• Power Requirements:
  • 220V, 50/60Hz for global compatibility with standard industrial power systems.

Industry Standards and Compliance

The Vacutainer Blood Draw Volume Tester complies with several industry standards for accuracy and reliability, ensuring that it meets the rigorous demands of healthcare, pharmaceuticals, and diagnostic laboratories. By adhering to established standards, this tester ensures that blood volume measurements are consistent, reliable, and reproducible.

Test Result Interpretation

The Vacutainer Blood Draw Volume Tester provides accurate results by calculating the difference in weight before and after the test. This weight change corresponds to the exact volume of blood drawn, ensuring that the proper amount of sample is collected for laboratory testing. The system eliminates the possibility of human error in volume measurement, ensuring consistency and high-quality results across all tests.
