US Patent Granted for a Novel Nasal Dressing – VelNez

Patent No.: US 10,293,075 B2
Date of the Patent Granted: May 21, 2019
Title of the Patent: Ready-to-use, Hydrophilic, Self-Dispersive, Fragmentable, and Biodegradable Porous Sponge Matrix and a Method of Manufacturing Thereof

NEED OF THE INVENTION:

Packing nasal and sinus cavities post functional endoscopic sinus surgery (FESS) is a routine procedure for most ENT surgeons. The packing is done to control postoperative haemorrhage and also to prevent the aspiration of blood in the postoperative period.

The packing also provides compression at the application site on the mucosal surface to inhibit tissue adhesion. These packs are made up of a variety of materials like cotton ribbon gauze, polyvinyl alcohol (PVA) sponge, Silastic balloon packs and are non-absorbable in nature.

Some centers even follow the traditional method of anterior nasal packing. This includes using cotton ribbon gauze saturated with liquid paraffin. Antibiotic ointments like Neosporin or bismuth iodoform paraffin paste (BIPP) may also be utilized.

These types of traditional nasal packings are often associated with significant patient discomfort and mucosal trauma and are preferably avoided, specifically after FESS, since these result in pressure necrosis, epistaxis upon removal, paraffin granulomas, and discomfort during placement and removal.

These dressings need to be removed and their removal is associated with various issues like pain, bleeding and makes the patient anxious. As per a study published in the Otolaryngol Head Neck Surg. Journal, patients consider the removal of a nasal pack as the most unpleasant part of the perioperative experience. Another study published in the American Journal of Rhinology shows that removal of nasal packs may cause mucosal trauma, which may lead to delayed healing and increased risk of scarring and synechiae formation.

We at Datt Mediproducts Pvt Ltd are the only Indian company that manufactures and sell a biodegradable nasal pack. VELNEZ^®, the present invention is now a patented product with a lot of patient and surgeon benefits.

ABOUT THE INVENTION:

The invention (VelNez^®) is a ready to use, self-dispersive, biodegradable and biocompatible device suitable for packing nasal and sinus cavities post surgeries.
VelNez^®acts as a space-occupying dressing and prevents adhesion by separating the compromised mucosal surfaces. It also reduces fibrosis at the same time and promotes healing and clotting.
The porous scaffold of the invention also acts as a therapeutic carrier for drug delivery or to carry any bioactive molecules, anti-microbial agents or other chemicals.
The porous sponge matrix comprises of a biocompatible and biodegradable polymer scaffold made up of a blend of synthetic and natural biopolymers as well as a 3-D scaffold polyelectrolyte complex (PEC) having vesicular micro-voids and an inner surface area larger than its outer surface area.

ADVANTAGES:

The unique composition results in rapid and uniform fragmentation.
The highly porous structure provides high absorption capacity.
Supports tissue regeneration and wound healing process.
Reduces fibrosis.
Provides compression at the tissue site and maintains sufficient compression strength while absorbing the natural fluids present in the nasal cavity.
Soft & flexible and can be easily cut and manipulated for surgeon preference and patient anatomy.
No post-operative adhesions as it separates the compromised mucosal surfaces.
No need for post-operative removal and hence atraumatic.
Ergonomic design for patient comfort.

VelNez^® fragments within a few days of application. The pain associated with the traditional nasal plug removal is completely eliminated with VelNez^® since such procedure is not necessary on application of VelNez^®.

Owing to these benefits, doctors are considering biodegradable dressings more than the counterparts these days. For more information on the nasal dressing and the differences in degradable and non-biodegradable nasal dressings, you can follow our previous blog.

Diabetes significantly increases the risk of developing chronic wounds, particularly foot ulcers. Effective wound care is crucial for preventing complications and promoting healing in diabetic patients. In this blog, you will explore the nature of diabetic wounds, prevention techniques, and management strategies to help healthcare professionals and patients navigate these challenges.

Understanding Diabetic Wounds

Diabetic wounds, especially foot ulcers, are common complications resulting from prolonged high blood sugar levels. These wounds often develop due to neuropathy (nerve damage) and peripheral arterial disease, which impair sensation and blood flow. Consequently, minor injuries can go unnoticed and progress into serious ulcers. Left untreated, these ulcers can lead to severe infections and, in extreme cases, amputations.

1. Prevention Techniques for Diabetic Ulcers:

Preventing diabetic ulcers is essential to reduce the risk of severe complications. Here are some effective prevention strategies.

2. Regular Foot Inspections:

Diabetic patients should inspect their feet (or have someone inspect it) on a daily basis for cuts, blisters, redness, or swelling. Early detection of potential issues can prevent minor problems from becoming serious ulcers.

3. Proper Footwear:

Wearing well-fitting shoes and socks designed for diabetics can prevent pressure points and reduce the risk of injuries.
Avoid wearing tight stockings or socks with elastic tops as they can reduce blood flow.
Avoid extreme hot or cold temperatures.
Do not treat corn or calluses on your own.
Avoiding barefoot walking, even at home, is crucial.

4. Good Hygiene:

Keeping feet clean and dry is essential. Patients should wash their feet daily with mild soap and water, then dry them thoroughly, especially between the toes.

5. Blood Sugar Control:

Maintaining optimal blood sugar levels through diet, exercise, and medication can significantly reduce the risk of neuropathy and poor circulation, which contribute to ulcer formation.

6. Regular Medical Foot Check-Ups:

Routine visits to a healthcare provider or a podiatrist for foot exams can help identify and address problems early.

7. Management Strategies for Diabetic Patients:

When ulcers do occur, effective management is vital to promote healing and prevent complications.

Here are some key strategies:

Wound Cleaning and Dressing: Keeping the ulcer clean and protected is essential. Cleaning the wound with a saline solution and using appropriate dressings, such as those provided by DMP Velvert®, can create an optimal healing environment. It provides a barrier to external contaminants, aids absorption of exudates and accelerates wound healing.
Debridement: Removing dead tissue from the wound (debridement) can accelerate the healing process. This procedure should be performed by a healthcare professional.

Pressure Offloading: Reducing pressure on the affected area is crucial. Patients may need special footwear, casts, or braces to alleviate pressure on the ulcer. Foot or mobility exercises also help in decreasing peak pressure, increasing foot and ankle range of motion and it improves neuropathy symptoms.

Infection Control: Monitoring for signs of infection and using antibiotics when necessary is critical. Proper wound care products, like Velvert®, which offer antimicrobial properties, can help prevent infections.
Blood Flow Improvement: Enhancing blood circulation through medical treatments or lifestyle changes can aid in the healing process. This might include medications, physical therapy, or surgical interventions. Revascularization results in increased tissue perfusion, which can further reduce amputation rates.

Diabetic ulcers are a serious complication of diabetes, but with proper prevention and management strategies, their impact can be significantly reduced. Regular foot inspections, good hygiene, appropriate footwear, and effective blood sugar control are key preventive measures. When ulcers do develop, it is best to catch them in the early stages when they are small, products combined with professional medical care, can promote healing and prevent complications.

At Datt Mediproducts, we offer Velvert®, an advanced wound care solution designed to aid in the management of diabetic ulcers. Velvert® dressings are crafted to provide superior moisture retention and protection, creating an optimal environment for wound healing. They also incorporate antimicrobial properties to reduce the risk of infection, which is crucial for diabetic patients. Velvert® is easy to apply and remove, ensuring minimal discomfort for patients.

When it comes to wound care, there’s a lot of advice floating around. Some of it is helpful, while other bits are more myth than fact. Let’s clear up some common wound care myths and get to the truth behind them.

Myth 1: Wounds Need Sunlight to Heal

Fact: While sunshine is great for your mood, it’s not beneficial for healing wounds. In fact, direct sunlight can actually cause burns and damage the tissues that are trying to heal. So, to promote proper healing, keep wounds covered and out of direct sunlight.

Myth 2: Wound Itching Means Healing

Fact: A bit of itching around a wound can be a sign that it’s healing, but it’s not always the case. Itching might also indicate an allergic reaction or infection. Monitor any itching along with other symptoms to ensure the healing process is on track.

Myth 3: Hydrogen Peroxide is the Best Cleaner for Wounds

Fact: Using hydrogen peroxide to clean wounds can actually slow down the healing process by damaging healthy cells. Instead, stick to gentle cleansing with mild soap and water to keep things clean without causing additional damage.

Myth 4: Keep Wounds Dry for Faster Healing

Fact: While it’s essential to keep wounds clean, keeping them too dry can actually slow down the healing process. Wounds heal better in a moist environment, so using dressings to maintain the right level of moisture can speed up recovery.

Understanding the Importance of Proper Wound Care

Wound care isn’t just about cleaning and covering a wound; it’s about understanding the underlying processes that help your body repair itself. Following evidence-based practices ensures that wounds heal properly and complications are minimized. Here’s why these practices are crucial:

Preventing Infections: Proper wound care minimizes the risk of infection, which can complicate healing and lead to more serious health issues.
Promoting Faster Healing: By maintaining a moist environment and protecting the wound, you accelerate the natural healing process.

When to Seek Professional Help

While minor cuts and scrapes can often be treated at home, certain situations warrant professional medical attention:

Deep or Large Wounds: Significant injuries that penetrate deep into the skin or are extensive in size require medical assessment.
Signs of Infection: Redness, swelling, increased pain, warmth around the wound, or pus are signs of infection that need medical intervention.
Delayed Healing: If a wound does not show signs of healing within a reasonable period, it’s important to consult a healthcare provider.

In a nutshell, taking care of wounds isn’t complicated, but it’s important to distinguish fact from fiction. By following evidence-based practices and seeking professional advice when needed, you can ensure your wounds heal properly and without unnecessary complications.
