The ruhr joints and holes joint torque test

demand

With health care application in liquid and gas small-bore connector related international standard focuses on their ease of use and resistance to leakage or wrong operation.The current的ISO 80369标准涵盖了一组测试方法，这些方法提供了广泛的功能检查矩阵，推荐用于此类组件的质量保证。 Mecmesin扭矩和力测试系统可帮助您根据这些ISO方法准备用于性能测试的连接器。

Small connectors are used in conjunction with the patient to use medical device or attachments, and in anesthesia, nerve radiation, tumor, hematology and radiology and healthcare applications such as in vitro diagnostic laboratory and pharmacy activity of conveying liquid or gas.

The current standard ISO 80369-20 specified requirement for the performance evaluation of small connector test methods.Withdraw and replace the other methods described in the standards (such as ISO 594 and BS EN 1701) is roughly same, some medical equipment manufacturers still follow this method, because this method approved by the FDA to continue testing equipment, until 31.12.2019.

Due to the different connector design is limited to certain areas, so the latest ISO 80369 document has been revised - the famous 6% taper Luer variant now intravascular or subcutaneous injection application only.Also include the lock, the lock (slip) and other instructions floating or rotating collar connector.ISO 594 is easy to assemble that exist in the test is considered too subjective, has been deleted.However, the use of the equipment is suitable for through perception associated with users to evaluate this feature.

The ISO 803969 test standard is intended to ensure that users of these components are easy to use;Patients themselves, relatives, home care providers as well as clinical users, such as doctors, nurses and emergency medical technicians.

20 part of ISO 80369 covers the following evaluation connector system performance test methods:

• Leak,
• Stress cracking
• Against overwhelming
• Through unscrew disconnected as well
• Resistance to axial force.

These methods are used for values that instructions applicable to the performance of the connector, details are as follows:

• Part 7: IV and subcutaneous injection (6% Luer connector.
• Part 3: for the application of gastrointestinal connector.
• Part 5: connector for limbs cuff air applications.
• Part 6: the application of nerve connector.

solution

For the force and torque equipment are in need of these methods of appropriate male/female connector "reference" (or "reference" accessories) to test the connector match the sample.Different tests of different size may need to refer to the connector.All methods need to be ready to test joint to make it conform to the specification.By the axial force and about 0.08 0.12 Nm of torque

BOB体育最新下载安装Mecmesin Helixa software control precision torque measurement system has the ability of applying axial load, is the ideal choice for this process.

In accordance with the requirements of performance evaluation to assemble the sample method each are not identical;Visual inspection or pressure measurement is related to a number of tests.

"Separation of axial load resistance", "unscrew separation force" and "beyond" resistance tests are need to force or torque testing system applied load, and according to the acceptable income measures the value of the parameter.Qualified or not quaBOB体育最新下载安装lified standard is easy to check, and controlled by the software Mecmesin system instructions.In addition, the data capture make Luer connector manufacturers to implement ISO 80369 Annex J and generate variable data for statistical analysis.As a manufacturer, you will not only receive a load value, but will also benefit from the graphical output, the graphical output can provide samples of the test of the performance characteristics of more understanding.BOB体育最新下载安装Mecmesin fully programmable software makes the r&d department can easily be applied beyond unique loading conditions required by the test standard.

Test equipment
