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 6: Long- and short-stretch bandages

    BLOG 6: Long- and short-stretch bandages

    When bandages are described as long- and short-stretch, this refers to the bandage’s ability to stretch. Thus long-stretch bandages will have high elasticity and short-stretch bandages low elasticity. This is not to be confused with high compression and low compression; as we have seen in the two previous posts, elasticity and compression are not the same thing, therefore one does not imply the other.

    As we mentioned, bandages can be classified according to their elasticity, either elastic or inelastic, and within the elastic category there are short-stretch and long-stretch bandages.

    Classification into short-stretch and long-stretch

    Although there are different opinions as to when a bandage is short-stretch and when it becomes long-traction, as a rule of thumb short stretch bandages are all those with an elasticity of between 10% and 90%-100%.

    A. Inelastic bandages: No extensibility or no stretch at all (<10% extensibility)

    B. Short-stretch elastic bandages (<100% extensibility)

    C. Long-stretch elastic bandages (>100% extensibility)

    Some examples of these bandages would be:

    LoPress (Hartmann)

    Normally these bandages are made primarily of cotton. They can also be cohesive, thus eliminating the need for a clip at the end of the bandage or some kind of fastening to maintain its position.

    • Long-stretch or high-elasticity bandages:

    On the other hand, long-stretch bandages are those that have an elasticity greater than 100%. Usually we find elasticities between 140% and 180%, although they can even reach 300% in some cases.

    Some examples of these bandages are:

    Elodur Forte (BSN)

    Elodur Forte (BSN)

    Kpress (URGO)

    Kpress (URGO)

    Dauerbinde K (L&R)

    Dauerbinde K (L&R)

    Rosidal (L&R)

    Vendari PRESIOFIX (Calvo Izquierdo S.L.)

    These bandages are normally made up of several types of yarns, at least one of which is extremely elastic, so that they allow elasticities of around 140%. If these yarns are natural, the elastic will likely be natural rubber; if they are synthetic, the elastic material will be elastane, polyamide or PBT.

    Relationship between short/long stretch and compression in bandages

    Finally, although the compression and the elasticity or stretch of the bandage have nothing to do with each other, it is true that they do have a certain relationship. Accordingly, a short-stretch bandage will exert one compressive effect on the patient, while a long-stretch bandage will have a different type of compressive effect.

    Without going into too much depth, as we will delve more deeply into this in future blog posts, short-stretch bandages, as they have less elasticity, work more when the patient is moving, and do not compress as much when the patient is at rest. On the other hand, long-stretch bandages, being more elastic and tending to recover their original size, exert some compression when the patient is at rest, i.e., they are more effective when the patient is immobile than when he or she is walking around.

    Calvo Izquierdo returns to MEDICA 2021.

    MEDICA is the leading trade fair for the global medical sector.

    Its high level of international influence and its reputation as a leading source of information in the field of medicine make it the meeting place for the international medical industry. The world’s largest event for the medical sector has been firmly established in the calendar of all experts for more than 40 years.

    There are many reasons why MEDICA is so unique. Firstly, the event is the world’s largest medical trade fair: it attracts several thousand exhibitors from more than 50 countries in the pavilions. In addition, every year, leading individuals from the fields of business, research and politics participate in this top-level event, along with tens of thousands of national and international experts and decision-makers from the industry. MEDICA includes an extensive exhibition and an ambitious framework program, which together present the entire spectrum of innovations for ambulatory and clinical care.

    And how could it be otherwise Calvo Izquierdo S.L. participated in this edition.

    MEDICA 2021
    In the past days November 15,16,17,18 we have been at our stand, four days of full power, knowledge transfer and networking in the face-to-face format.
     
    We are very happy with the results obtained. We hope that the next MEDICA 2022 will be as successful as this one has been.

    New R&D project based on natural xerophytic plant extracts

    New R&D project based on natural xerophytic plant extracts

    CALVO IZQUIERDO, S.L. participates in the R&D project “PRONOS – R&D of new antimicrobial products based on natural extracts of xerophytic plants for prevention of nosocomial infections by cleaning surfaces and skin”, funded by the AVI and the European Union through the ERDF. This is a business value chain consolidation project, which started in February 2021 and will end in December 2022. In addition to CALVO IZQUIERDO, S.L., the companies VIVEROS CANÓS, S.L., ESPECIALIDADES FARMACÉUTICAS CENTRUM, S.A., ATQ QUIMYSER, S.L. and KOROTT, S.L. are also participating.

    The main objective of the project is to investigate ingredients obtained from natural extracts of xerophytic (dry environment) plants with antimicrobial properties, for the development of surface cleaning and skin care products in the healthcare environment, which contribute to the prevention of nosocomial infections (hospital-acquired infections).

    It is a health concern that the efficacy of the arsenal of biocidal substances is increasingly diminishing in the face of the growing antimicrobial resistance (AMR) of the microorganisms responsible for infections. It is estimated that between 6 and 10% of patients admitted to a hospital may suffer a nosocomial infection. This problem changes the course of hospitalization and exposes the patient to new risk situations, increasing hospital morbidity and mortality, hospital stay and health care costs. Research in this field is now focusing on ingredients of natural origin, for two reasons: they have been shown to be effective against dangerous pathogens; and their renewable and biodegradable origin is environmentally friendly and compatible with people’s health.

    As a result of the project, it is expected to create and consolidate a value chain for the manufacture of products with antimicrobial activity, based on active ingredients of natural origin. Thus, as a result of the project, it is expected to obtain products of natural origin for surface cleaning and skin care and hygiene, with antimicrobial activity for sanitary use in hospitals. Specifically, CALVO IZQUIERDO, S.L. expects to develop new bandages with antimicrobial finish for the prevention of infections in the sanitary field.

    The project impacts the value chain of natural products with antimicrobial properties, from the study and selection of the species, to obtaining the functional active principles, through their stabilization and conservation, to their ultimate application in health products.
