The HBLT, a hydraulic pressure tester, is an ideal choice for testing products that involve the use of liquids. Its versatility extends beyond balloon catheter testing, as it can be employed to evaluate a wide range of medical devices. HBLT equipment serves as a programmable pressure source, catering to any application that requires liquid-based pressure testing data.

Furthermore, this equipment has broader applications that extend across different divisions and teams. It proves valuable for research and development, aiding in the development of new products. Quality control teams can rely on it for design assurance and AQL testing. Additionally, marketing teams can utilize it for comparative testing data, making it a valuable asset in various aspects of the medical device industry.

• The HBLT is used to test the individual parts including the drip chamber, fittings, and tubing or the entire set up.

Check Valves

• The HBLT is used to ensure the valves function as expected with no leaks.

Inline filters, Blood filter systems, IV bag testing

• HBLT is used to Pressure test filters and IV bag systems.

Needleless injection sites, Stopcocks

• HBLT is used to identify cracking pressure, leak testing, burst testing.

Let’s Discuss You Application Needs

Pressure Manager© is a Windows® based program that can manage the setup, operation and data collection of the Crescent Design Hydraulic Burst Leak Tester (HBLT). The program allows a user to quickly enter, edit and run tests or scripts. While executing a test or script, Pressure Manager© displays a graph of the current pressure, maximum pressure, and one of four volume traces. In addition, Pressure Manager allows the user to save the data collected for later analysis or graphing.

Pressure Manager provides these four primary advantages over standalone HBLT operations.

• Provides both speed and ease of operation The Windows interface is familiar and provides quicker data entry and operational control.
• Graphs provide more information about the behavior of the product during the test. The operator can detect evidence of product compliance or leaks prior to their detection by the HBLT.
• Collects the data for future detailed analysis. The data is saved in a form that most graphing and analysis programs can import.
• Provides custom scripting capabilities. This allows the operator to design a test specific to a product. The scripting also allows use of the volume control commands that are not available from the HBLT alone.

Balloon Compliance Testing

Contact and Non-Contact, Single and Multi-point Measurement

Balloon compliance testing compares balloon pressure to resulting balloon diameter across a full range of pressure up to 25% above rates burst pressure. Our Balloon Compliance Test Fixture (CTF) allows for the automatic contact measurement of products while submerged in a water bath. A standard, low-force Mitutoyo Digimatic gauge is mounted on an adjustable stand that will accommodate water baths of various depths. The Balloon Compliance Test  fixturing was designed to accommodate a wide range of balloon product types and sizes and all components are corrosion resistant.

Crescent Design’s non-contact, single point diameter measurement systems employ a Keyence Optical Micrometer mounted to a temperature-controlled water bath with specially designed product fixturing.

The Positioning Controller system offers non-contact, multi-point diameter measurement readings during balloon compliance testing. The Positioning Controller consists of a water bath and Keyence LS7070 micrometer mounted to a translation stage that allows the micrometer to be positioned horizontally. It is available with a 14-inch bath (8 inches of travel) or a 20-inch bath (14 inches of travel).
