Peristaltic Insulin Pump Test

Medical Device Evaluation

Assess design, ergonomics, and safety of medical devices with pressure mapping.

Optimize Medical Device Functionality

Challenge

Manufacturers and researchers continuously strive to validate or improve efficiency and accuracy of medical devices and precision tools. Whether evaluating the effectiveness of a surgical apparatus or ensuring the fit of a health-monitoring device, contact pressure distribution plays a critical role. Interface pressure data can be instrumental to the safety and accuracy of various medical procedures.

Solution

The I-Scan™ pressure mapping system is used by engineers and researchers throughout the medical device industry to help develop innovative tools and assess product quality, ergonomics, and even manufacturing equipment.  I-Scan is a powerful tool that accurately measures and analyzes interface pressure between two surfaces.  The system is comprised of of a thin and flexible sensor, data acquisition electronics, and analysis software.

Laparoscopic Surgical Gripper ToolLaparoscopic Surgical Gripper Tool

I-Scan can be used to test surgical gripping devices to evaluate hinge design.  The gripper clamps down on the sensor, while software displays the pressure distribution in real-time.  Various hinge designs can be tested and compared to achieve optimal gripping force.

I-Scan provides an efficient way to test the adhesion
necessary to repair (left images) or replace (right

optimize device performance, as well as the surgical
process.

This test established that a knee joint implant is working
properly, by revealing pressure uniformity between the
medial and lateral compartments.

the functionality of a tourniquet cuff.

Peristaltic Insulin PumpPeristaltic Insulin Pump

To determine if the proper amount of insulin is being
delivered, a sensor is placed between the roller and
plastic tube of an insulin pump. The left image shows
the pressure profile of the roller at one point during
a stroke; the right image shows an entire stroke. The
pressure images reveal an uneven loading on the tube
throughout the stroke.
