Medical Device Testing Attachments

Home > Applications > Medical Device Testing Attachments

Any of the texture analyser range can be used for the product tests listed below.

A selection of special attachments and typical measurements are also shown which are commonly used in this application area. However, this does not show the complete range of attachments available for the testing of medical device products. Test procedures include: compression, puncture/penetration, tension, fracture/bending, extrusion, cutting/shearing.

Typical measurements include:

Needle Sharpness

Extrusion force: syringes

Metering valve performance: inhalers

Material Strength (tensile or compressive): catheters, tubing, surgical gloves, contact lenses

Tensile Strength: bandages, medical gloves, sutures, stents, adhesives

Compression fatigue: breast implants

Bond Strength: between thread and suture needle

Puncture Resistance: breast implants

Syringeability (expulsion and extraction forces)

Metered Dose Inhaler

Hypodermic Needle Sharpness Testing

Tensile Grips

Metered Dose Inhaler
The metering valve, whose
performance is assessed with this
test, is a critical component of a
finished metered-dose inhaler.
Patients need to rely on their
inhaler to provide them with the
required medication which is often
at a crucial time when physical
strength may be very low.

Syringe & Hypodermic Needle
Needle sharpness is an important
characteristic for patient comfort.
This is determined by a puncture
test where the needle is pushed
through a substrate which is
rigidly held. The syringe body dispenses its contents by forward
extrusion and is tested by
measuring the average and peak
extrusion force.

Tensile Grips
Used for the assessment of
Seal Strength (an important
characteristic of packaging to
ensure sterile integrity).

Contact Lense Compression

Compression Probes
Allow the hardness assessment of
e.g. contact lenses

Application Studies are available for the testing of MEDICAL DEVICE products using the TA.XT2i, TA.XTplus, TA.XTExpress or TA.HDplus texture analysers.

In addition, scientific papers have been published which reference the use of the TA.XT2i/TA.XTplus/TA.HDplus in the testing of MEDICAL DEVICE products.
