Catheter Burst Pressure Tester

Main Uses of the Catheter Burst Pressure Tester

The catheter burst pressure tester is a key device used to evaluate catheter performance in the medical field. Its main uses include: 

Evaluating Catheter Pressure - Resistance Performance: By simulating high - pressure conditions in actual usage scenarios, gradually increasing the pressure applied to the catheter until it bursts, and recording the pressure at which the catheter bursts, the pressure - resistance performance of the catheter can be evaluated. 

 Quality Control: During the production process of catheters, the tester can be used in the quality - control process. It helps manufacturers conduct performance tests on each batch of catheters to ensure that every catheter meets the quality standards. 

Medical Device R & D: In the R & D stage of medical devices, the tester can be used to evaluate the performance of catheters made of different materials and with different design schemes in high - pressure environments, providing a basis for the optimized design of products. 

Third - Party Testing and Certification: The tester is also widely used in third - party testing institutions and quality certification institutions, providing technical support for the certification and quality inspection of medical devices.

Compliance Standards

YY/T 1536 - 2017 YY 0285.1 - 2017, etc.

Technical Parameters

Testing Accuracy: With a high - precision measurement system, the error is generally not more than ±2%FS (full - scale error). This ensures the accuracy and reliability of the test results. 

Testing Flow: Some testers may have the function of testing flow, and the flow range is generally 0 - 500ml or other applicable ranges. Flow testing helps evaluate the performance of catheters during power injection. 

Water Bath Temperature: During the testing process, the water bath temperature is generally controlled at 37°C±1°C or 37°C±2°C to simulate the human body temperature environment. This helps ensure the accuracy and comparability of the test results. 

Data Recording and Display: The tester should have a data - recording function and be able to store multiple groups of test data. Meanwhile, the test data should be presented in the form of charts or curves to enable users to intuitively understand the performance of catheters. 

Automated Control: Some testers are equipped with automated control systems, which can automatically complete the testing process and reduce errors caused by human operations. This improves the testing efficiency and accuracy.

FAQ

(1)What is a Catheter Burst Pressure Tester used for?

A Catheter Burst Pressure Tester is used to evaluate the pressure resistance and burst strength of medical catheters by applying controlled internal pressure until the catheter reaches failure. The test provides quantitative data about the maximum pressure a catheter can withstand under specified conditions. It is commonly used by catheter manufacturers, medical device companies, and testing laboratories for product verification, quality control, and design evaluation.

(2)How is catheter burst pressure measured?

A Catheter Burst Pressure Testing Machine measures burst pressure by increasing the internal pressure of a catheter sample at a controlled rate while monitoring pressure changes. The test continues until the catheter ruptures, leaks, or reaches the defined failure point. The highest recorded pressure value is used as the burst pressure result, which helps evaluate the structural strength and reliability of the catheter design.

(3)Why is burst pressure testing important for medical catheters?

Medical catheters may experience internal pressure during clinical applications such as fluid delivery, drainage, or interventional procedures. Catheter burst pressure testing helps manufacturers verify whether products have sufficient pressure resistance and whether materials, bonding processes, and manufacturing methods provide consistent performance. The test is an important part of medical device performance evaluation and quality control.

(4)What types of catheters can be tested with a Catheter Burst Pressure Tester?

A Medical Catheter Burst Pressure Tester can be used for evaluating different catheter products depending on the equipment configuration and test fixture design, including balloon catheters, cardiovascular catheters, infusion catheters, drainage catheters, and other medical tubing products. The suitable testing method depends on the catheter structure, intended application, and manufacturer testing requirements.

(5)Which standards are related to catheter burst pressure testing?

Catheter pressure testing requirements depend on the catheter type and intended application. Commonly referenced standards include the ISO 10555 series for intravascular catheters and ISO 13485 for medical device quality management systems. Specific burst pressure test procedures are usually defined according to the product design, applicable regulations, customer requirements, and internal validation methods.

(6)What factors can affect catheter burst pressure test results?

The results of a Catheter Pressure Tester can be affected by factors such as catheter material, wall thickness, manufacturing process, bonding strength, test pressure rate, sample preparation, temperature, and connection method. To obtain reliable and comparable results, laboratories need to control test conditions and follow a consistent testing procedure.

(7)How does a Catheter Burst Pressure Tester help medical device manufacturers?

A Catheter Burst Pressure Tester provides measurable pressure performance data that helps manufacturers evaluate product reliability during development and production. Test results can be used to compare different materials, optimize catheter structures, monitor manufacturing consistency, and identify potential weaknesses before products enter clinical use or commercial production.

(8)How should users choose a suitable Catheter Burst Pressure Testing Machine?

When selecting a Catheter Burst Pressure Testing Machine, users should consider the catheter types being tested, required pressure range, measurement accuracy, fixture compatibility, data recording functions, and applicable testing methods. Medical device manufacturers should choose equipment that matches their actual product specifications and quality control requirements to ensure meaningful and repeatable test results.
