When testing the strength and elongation of medical gloves to uphold international and FDA standards, one has to be careful with measuring strain without damage.
Pneumatic grips can be used with testing soft tissue substrates to understand the wound closure strength of tissue adhesives, following ASTM F2458.
To follow ASTM F2516, the Advanced Video Extensometer allows for accurate strain measurement of nitinol wire for biomedical uses without common failures.
With angioplasty, stents need to be removed axially when the balloon catheter is uninflated. Tests need to be performed to find the force needed to remove it safely.
Pneumatic side action grips or mechanical elastomeric grips may be used in testing the physical properties of medical gloves, according to BS EN 455-2.
For tensile testing of catheter tubing, Instron's 3345 system with pneumatic cord and yarn grips determines the breaking strength for quality control.
Testing contact lenses testing presents challenges with the delicacy and small size of the contacts, as well as the required simulated environment.
Automatic extensometers provide the most accuracy for tensile and cyclic testing of delicate Nitinol wire used in the biomedical industry.
With a 5969 testing system and pneumatic side action grips, we are able to test tensile and yield strength of hypodermic needles without early failure from gripping.
Instron's syringe test fixture works for various specifications and follows ISO 7886-1 to test the aspiration and injection of liquids.
The 8874 system can test the laxity of knee joints in simulated conditions before they are used for a total knee replacement and impacted by the surgery.
Many soft tissues, such as skin or collagen, are delicate specimens with low ultimate strength values and require a testing system to be highly sensitive to low-force measurements and small displacements.
A BioBox temperature chamber can solve the problem of a simulated natural environment for testing medical materials that cannot be placed in a fluid bath.
To avoid slippage, test medical tubing and catheters with pneumatic cord and yarn grips or pneumatic side action grips with rubber faces, depending on the material.
Orthopedic micro-implants used to treat bone problems and soft tissue injuries need to be tested in simulated loading conditions to prevent failure.
For tensile testing of polymeric membranes for the biomedical field, challenges are associated with gripping the wet specimens without slippage or tearing.
In testing soft biological tissues, the 250 N capacity pneumatic grips with either serrated faces or smooth faces and sandpaper prevent error and slippage.
A 3345 with a 1 kN load cell and 1 kN capacity pneumatic cord and yarn grips can be used to produce tensile tests for surgical sutures and knots.
To test the medical performance of surgical tubing to prevent failure of the tubes, joints, and additional friction, use correct gripping for correct results.
To perform tensile tests for surgical tubing, use mechanical screw action grips for components and pneumatic grips for the tubing itself to prevent slipping.
Instron's Bath and Submersible Pneumatic Grips can assist in in-vitro testing of soft tissues and biomaterials, which are fragile and require low force measurements.
Non-contacting extensometers can be used to measure strain of biological specimens without early damage, and various techniques can be used to mark the soft tissues.
Instron's XY Test Stage mounts to various universal testing systems to work as a precise force applicator without touching the wrong components.
Tests to determine the bond strength and tensile adhesion of materials in restorative dentistry can be created using a 5900, 3300, or ElectroPuls test instrument.
