Adhesives in Medical Sector

Nowadays, the medical devices are improving everyday with the advancement in technologies, and they are becoming more practical whether they are designed to be used outside the body (surgical tools) or inside the body (diagnostic tools, monitoring tools etc.). No matter where the devices will be used, they generally consist of parts that requires an assembly in some way. Since these devices will be used on human body, the adhesives which will be used on these devices must be chosen with utmost rigor.

Why Choose Adhesives in Medical Sector

In recent years, adhesives have started to replace other fastening methods for the assembly process of many medical devices. The benefits of adhesives over other mechanical bonding techniques can be explained as;

  • Adhesives from a stronger and more uniform bond,
  • Uniform stress distribution on the surface,
  • Ability to bond different substrates as well as hard to bond materials,
  • Can be cost effective,
  • Can save time,
  • Allows flexibility in design,
  • Easier to automate the process,

and many other reasons…

Medical Grade Adhesives

Adhesives can only be declared fit to be used for medical purposes if they pass certain rigorous tests. USP VI Standardization and ISO 10993 (ISO 10993 -4, -5, -6, -10, -11) Certification tests are the two main tests used to validate the safety & quality of the medical adhesives.

The medical grade adhesives can be divided into two groups as synthetic products which are made from materials like;

  • Acrylic

  • Polyurethane

  • Silicone

  • Polyethylene Glycol (PEG)

  • Cyanoacrylate

  • Epoxy

and natural products which are made from materials like;

  • Albumin

  • Collagen

  • Fibrin

  • Polysaccharide

  • Gelatin

and so on…

Where Adhesives in Medical Sector Are Used

Materials such as polymers, ceramic, and glass play an important role in the medical sector. Molding the parts made from these said materials is out of the question due to the health regulations and using mechanical bonding techniques may damage the surface of the parts and the parts themselves. Therefore, using adhesives in medical sector become an excellent choice for the bonding applications. Moreover, the medical grade adhesives can be designed in various ways to answer various requirements which the medical sector needs while still being safe to be use on human body. Medical adhesives are generally used in;

  • Medical Tools & Disposables

  • Dialysis Tools

  • Patches & Sensors

  • Needles & Syringes

  • Catheters

  • Tubes

  • Wound Closure & Management

and many more…

Choosing Correct Adhesives in Medical Sector

It is important to remember that not all medical adhesives are appropriate for all applications, hence the properties of each adhesive must be considered beforehand, in order to choose the correct adhesive for the correct application and/or machine. Other points to address when selecting the correct adhesive are;

  • Materials from which the parts are made from,
  • The surface characteristics of the substrates,
  • Strength of the desired bond,
  • Surface area on which the adhesive will be applied to,
  • How and where the device will be used,
  • Environmental conditions (heat, humidity, light, chemicals etc.),
  • Storage conditions,
  • Desired lifespan of the device,
  • Desired method of the application of adhesive

and so on…
