BLOG 7: Types of bandages according to their composition.

There are many ways to classify bandages. In this and the following post we are going to deal with the two most widespread ones. First, in this blog post we will classify bandages according to the material and composition, and then, in BLOG 8, we will categorize bandages according to their purpose or function when applied. Although these classifications are common in many points, in others they differ.

Gauze bandage

This type of bandage is widely used as a support bandage. It is sometimes applied directly to wounds as it can be impregnated with Vaseline or medication. At the same time, it allows air to circulate through it, enabling very good breathability for the wound. Gauze bandages have little or no elasticity. In the past, gauze bandages were quite common, although in recent years they have fallen into disuse.

Elastic bandages

Venda elástica

These are bandages that adapt very well to any area of the body thanks to their elasticity. Their main use is to hold and support, allowing the wounds to be protected from the environment and preventing them from becoming infected. Elastic bandages are usually made of synthetic and natural yarns such as: cotton, viscose, polyamide and/or PBT.

As we can imagine, elasticity is one of the key factors of this bandage, normally being around 100% and about 140% for crepe elastic bandages.

Crepe elastic bandage

Venda de crepe

This is a particular type of elastic bandage, so called because of the shape of the fabric that forms it. It is arguably the most widespread type of elastic bandage. It usually has two longitudinal lines on the sides of the bandage in red or blue. It is a full-bodied bandage but at the same time it is very porous and breathable.

The main characteristic of this bandage is the grammage. Some of the most common standards are 70 gr/m2, 90 gr/m2 or 100 gr/m2.

Cohesive elastic bandages

Venda de crepe

This type of bandage is an elastic bandage that has been impregnated with a cohesive material, which gives the bandage its properties. Cohesive elastic bandages are widespread in Europe and the Americas. Its main advantage, as we have already mentioned, is that because the bandage adheres to itself, it remains in place for much longer. In addition, unlike adhesive bandages, these bandages do not stick to the skin or clothing, thus facilitating their removal.

Padding bandages

Venda de crepe

This type of bandage is an elastic bandage that has been impregnated with a cohesive material, which gives the bandage its properties. Cohesive elastic bandages are widespread in Europe and the Americas. Its main advantage, as we have already mentioned, is that because the bandage adheres to itself, it remains in place for much longer. In addition, unlike adhesive bandages, these bandages do not stick to the skin or clothing, thus facilitating their removal.

Foam bandages

Venda de espuma (Pre-tape)

They have a similar purpose to the padding bandages but are made of polyurethane of greater or lesser thickness. Sometimes this material is impregnated with a substance to eliminate odors, relieve itching or reduce inflammation. They are also often referred to as pre-tape bandages.

Elastic adhesive bandages

Venda de espuma (Pre-tape)

Estas vendas están diseñadas para reducir el movimiento parcial de alguna articulación o alguna parte del cuerpo. Contienen un adhesivo que permite que se fijen a diferentes superficies y contiene un alto poder adhesivo. Es una venda muy utilizada en la aplicación de vendajes funcionales.

Plaster of Paris Bandages

Venda de yeso

These bandages are designed to reduce partial movement of a joint or body part. They contain an adhesive that allows them to be attached to different surfaces and have a high adhesive power. They are widely used in the application of functional bandages.

Polyester fiber bandages

Venda de yeso

They have the same purpose and use as plaster bandages but are made from synthetic materials. While they are more expensive than plaster, they have the advantage that, once correctly applied, the patient can get wet without damaging the bandage. Polyester fiber bandages are also much lighter than plaster bandages.

Tubular bandages

Venda tubular de compresión

Tubular bandages are tube-shaped and there are three main types. First, there is the tubular compression bandage, which generates a slight compression on the applied area. Second, the support bandage is an elastic bandage that serves as protection before another type of bandage is applied. Finally, the mesh bandage is a very elastic bandage used as a support for dressings and other bandages. This type of bandage is easy to apply. The materials from which it is composed are very diverse

Plasters and tapes

Venda tubular de compresión

Plasters are bandages that are impregnated with adhesive, but unlike elastic adhesive bandages, these bandages have little or no elasticity. They are made of different materials: paper plasters, plastic plasters, fabric plasters and TNT plasters. Finally, there are the ones known as tapes, which are like plasters but different. Although they are all made of a fabric impregnated with adhesive, their functions are very diverse and their use is very versatile, from fixing bandages or other objects, to their use in functional or compression bandages.

In the case of tapes, they are inelastic adhesive bandages which, when properly applied, form undulations on the skin to increase the subdermal space and facilitate lymphatic and blood flow.

Kinesiology tape

Venda tubular de compresión

These are a very specific type of tape that due to the undulations of the fabric and always being applied by professionals in the sector, allows muscle recovery in a faster and more effective way. They are widely used in fields such as physiotherapy and sports rehabilitation.

This is an adhesive bandage, with elasticity only in the longitudinal direction.

Como podemos comprobar existen multitud de vendas y su uso es muy variado, es muy importante conocer todo

As we can see, there are a multitude of bandages and their use is quite varied. It is very important to be familiar with all these types, as well as their compositions, because their functions and the way they are applied depend greatly on this knowledge.

    BLOG 3: Latex and latex-free bandages

    BLOG 3: Latex and latex-free bandages

    Latex in bandages has been a common compound for many years, but over the last few decades its use has been declining. The main problem with latex is that it provokes an allergic reaction in some people, causing serious harm that may even produce asphyxia in some rare cases.

    Bandages with latex

    Latex is a derivative of natural rubber that contains certain enzymes that can be allergic to a certain percentage of the population. In the last two decades, latex allergy has become a health problem of worldwide relevance. It has been estimated that between 0.3 and 1% of the general population is allergic to this substance. In most cases, this allergy generates a very mild reaction with itching or reddening of the skin, but in a small percentage of cases the patient may suffer an anaphylactic reaction that may even result in death.

    In other countries there are specific products with latex, but in Spain, as well as in the rest of Europe, the authorities are trying to phase it out. What latex provides are certain properties that are very desirable in the manufacturing of some bandages:

    • Elasticity: latex is found in some natural yarns such as rubber and these yarns have good elasticity.
    • Cohesiveness: latex has the property that it adheres to itself but not to skin or tissues, allowing a more stable, durable and consistent hold and support, while permitting the removal of the bandage to be easy and painless.
    • Compactness: in some bandages such as plaster casts, latex is used to provide consistency and allow for a more rigid bandage.

    Latex is still used in the veterinary field, which does not impose a specific “latex-free” rule, unlike the healthcare sector.

    Latex-free bandages

    To avoid using elastic yarns containing natural rubber and latex, the Dupont company developed a very thin but highly elastic yarn: elastane or spandex. This yarn is the latex-free version of the rubber yarns used years ago. To learn more about the yarns most commonly used in the manufacture of bandages, visit our post: What types of yarns are used in bandages?

    Regarding the manufacture of cohesive bandages, the transition has also been progressive but steady. Currently, to replace latex, several latex-free components are being used, such as polyisoprene, which, although it endows the bandages with the same cohesive properties, being synthetic it does not contain latex.

    As we have been able to appreciate in this post, the use of latex is being phased out, especially in the medical sector and for bandages for humans. In the next post we will discuss different types of bandages, noting the presence or absence of this component, as it has become a very important characteristic to consider.

      Calvo Izquierdo strengthens its presence at MEDICA 2015 as exhibitor

       

      The Valencian company Calvo Izquierdo strengthened its presence this year at the MEDICA 2015 fair, attending as an exhibitor for the third consecutive year. This is the largest meeting of the health care industry, held in the German city of Dusseldorf, from 16 to 19 November.

      For four days, visitors were able to learn about the main innovations that Calvo Izquierdo has introduced in the market, such as the padding bandages and the bandages with cold and heat thermal properties. The bandages with thermal properties are the first results of a research project developed by the company called VENDAGEN 2.0, which is supported by the Center for the Development of Industrial Technology (CDTI).

      MEDICA has around 5,000 exhibitors in 19 halls, which are visited by 130,000 healthcare professionals. This fair is characterized by a strong international character, since more than half of the visitors and 78% of the exhibitors are from outside Germany.

      This international aspect is directly linked to Calvo Izquierdo’s strategy of opening new markets in which to market its medical and healthcare products.

      We look forward to your visit in next year’s edition – MEDICA 2016 November 14/17.
