Vacuum Blood Collection Tube Suction Volume Tester

In the medical field, particularly in processes involving blood sample collection, the accuracy of the suction volume of Vacuum Blood Collection Tube Suction Volume Testers is crucial. Specifically designed for testing the suction volume of single-use human venous blood sample collection containers, this device accurately measures the suction volume of vacuum blood collection tubes at different altitudes, ensuring compliance with relevant standards and providing a reliable foundation for clinical diagnosis and medical research.

Applications

The Vacuum Blood Collection Tube Aspiration Volume Tester is mainly used to detect the aspiration volume of disposable human venous blood sampling containers, especially to check whether they meet the standard requirements in different altitude areas. The tester precisely measures the aspiration volume of blood collection tubes by simulating different altitude or air pressure conditions, thereby evaluating the performance of blood collection tubes in various environments. This is crucial for ensuring the accuracy and reliability of blood collection tubes in actual use, and helps maintain the quality of blood samples and the accuracy of diagnostic results.

Standards

The design and manufacture of the Vacuum Blood Collection Tube Aspiration Volume Tester must comply with relevant medical industry standards, such as YY 0314 - 2021Disposable Human Venous Blood Sampling Containers. This standard clearly specifies key indicators, including the error range of the aspiration volume of blood collection tubes, container leakage tests, and container strength tests, to ensure the usability and safety of blood collection tubes. The tester must strictly adhere to these standards during the design and manufacturing process to ensure the accuracy and reliability of test results.

Features

1.Adoption of PLC Industrial Control System: The PLC industrial control system offers high stability and reliability, ensuring precise control of the testing process. It can quickly respond to various commands, enabling accurate adjustment of parameters such as test pressure and time, guaranteeing high accuracy and repeatability of test results. For example, when performing multiple blood collection tube aspiration volume tests, the PLC control system ensures consistent test conditions each time, improving testing efficiency and accuracy.

2. 7-inch HMI Touchscreen: Operation is simpler and more intuitive. Test personnel can easily set test parameters and view test results via the touchscreen, eliminating complex operating procedures. Even first-time users can quickly master the operation method, improving work efficiency.

3. Extra-thick Acrylic Vacuum Chamber: Provides excellent sealing and visibility. The sealing ensures the stability of the pressure environment during testing, preventing external air interference with test results; the visibility allows test personnel to observe the puncture and blood collection process of the blood collection tube, enabling timely detection and resolution of problems.

4. Built-in Vacuum Device:Eliminates the need for an external air source, reducing the complexity and cost of equipment use. Users only need to connect the power supply to quickly start testing, making it convenient and suitable for testing needs in various locations.

Test Procedures

1. Sample Preparation

Randomly select 30 blood collection tubes and equilibrate them for 1 hour at 20℃±2℃.

Use standard Grade 3 water as the medium to avoid temperature fluctuations affecting density.

2. Equipment Calibration

Connect the pre-vacuum blood collection tube aspiration volume tester and vacuum pump, and remove air bubbles from the tubing.

Calibrate the vacuum level to the target value (e.g., -30 kPa for simulating an altitude of 3000 meters).

3. Test Execution

Insert the blood collection tube into the puncture site of the testing system, start the vacuum pump, and maintain stable pressure for 1 minute.

Record the weight difference of the blood collection tube before and after water aspiration, and calculate the individual and batch average aspiration volume.

4. Result Judgment

If the batch average aspiration volume is within ±10% of the nominal value, it is judged as qualified.

Generate a test report, including the pressure-time curve, weight data, and deviation analysis.
