A device similar to bandage has been announced as a better alternative to staples and sutures.The device is called the microMend Skin Closure Device made of a thin adhesive backing with two arrays of tiny micro-staples on each side.These micro-staples anchor the device on the skin of the patient to cover the wound safely and securely.The design allows conformity with the patient's movements and offers strength similar to sutures.The device does not cause pain and may stay on the wound until healed.

"Although we ended up using metal rather than chitosan, Dr.Rolandi's research got me thinking about the use of microneedles to close wounds," said Dr.Ron Berenson, a biotech and medical device entrepreneur.Berenson envisioned the concept when he was serving as an entrepreneur-in-residence at the University of Washington's innovation hub in 2012.During that time, Dr.Marco Rolandi was working on a project using tiny chitosan microneedles to heal wounds.Berenson was inspired by Roland's idea of microneedles to help heal wounds faster.

microMend offers many advantages to both patients and doctors compared with staples and sutures.It leaves a smaller scar which essentially reduces the risk of infection, decreases inflammation, has proper distribution of tension on the skin, does not cause tissue damage at the wound site, does not require needles, and covers the wound without needing an additional layer of adhesive strip.Doctors will find that the device is easier to use because there's no need for needle-sticks, it only requires minimal training to use, and it is simple to remove that patients can do it themselves.

The company, KitoTech Medical, that made the new closure device is focusing on the application of microMend in dermatological and plastic surgeries.But Berenson pointed that the device can also be used in different medical applications, such as emergency settings or other surgeries including spinal and vascular procedures.

Different Types of Wounds

Abrasion, laceration, puncture, and avulsion are four major types of open wounds.Depending on what caused the wound and how deep the injury was, a risk of infection may occur.

1.Abrasion - Abrasions happen when the skin rubs or scrapes against a hard or rough surface, damaging the surface of the skin.Most abrasions have minimal bleeding but you still need to clean and disinfect the wound site to avoid infection.

2.Laceration - Lacerations are deep cuts or tearing of the skin that can be caused by sharp objects, such as knives, scissors, tools, and machinery.The bleeding in lacerations is rapid and extensive.

3.Punctures - Punctures are small rounded wounds from pointed objects, such as nails and needles.Punctures may or may not bleed but wounds can be deep enough to damage internal organs beyond the wound site.Puncture wounds are closely connected with tetanus because the bacteria usually inhabit objects with rust.

4.Avulsion - Avulsions are wounds in which the skin and tissues have been partially or completely torn away.These wounds are very common in violent accidents, explosions, and gunshots, People may die in shock from these wounds because of the heavy and rapid bleeding.

The most common complication of open wounds is an infection.An infected wound may have pus, a foul smell or drainage.  It is caused by the microbes invading the wound site.

Inflammation is caused by the interaction of the immune system with the foreign microorganisms that entered the wound site.Inflamed wounds usually appear red, feel hot and swollen, and may even be painful.

Body parts nearby the wound side can lose functionality because of trauma or pain.The loss can be temporary or permanent, depending on the extent of the injury and which body part has been injured.

Wounds can lead to scarring after being healed.Moreover, the healing process may leave deformity of affected areas, such as wounds from a gunshot, deep lacerations, and punctures.

Taking Care of Open Wounds

The first thing that needs to be done is to stop the bleeding to prevent blood loss.Usually, covering the wound with a clean bandage and applying gentle pressure for 20 to 30 minutes will be enough for the blood to clot.

The next thing is cleaning the wound site.Remove any objects on or near the wound including the causative object, wash the wound with water, and disinfect with a sterile solution to get rid of germs and debris.

After cleaning the wound, apply some topical antibiotic.If the wound is deep, visit your doctor because he/she may need to prescribe oral antibiotics to prevent infection.

Once you have cleaned and treated the wound, cover it with a bandage, wound dressings, staples, or stitches.You also need to change the dressing regularly especially if the wound is wet and draining.
