US Patent Granted for a Novel Nasal Dressing – VelNez TM
US Patent Granted for a Novel Nasal Dressing – VelNez TM

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.

CHOOSING THE RIGHT DRESSING

Chronic wounds are wounds that fail to heal within the expected time frame, typically lasting more than four weeks. They can arise due to underlying conditions such as diabetes, prolonged pressure, or venous insufficiency. Common types include diabetic ulcers, bed sores, and venous leg ulcers.

Managing chronic wounds presents significant challenges, including a high risk of infection, slow healing, and patient discomfort. The right dressing plays a crucial role in creating an optimal healing environment, reducing complications, and improving patient outcomes.

Types of Chronic Wounds and Their Dressing Needs

Diabetic Ulcers

  • A Diabetic foot ulcer is a debilitating complication of diabetes mellitus. It refers  to an open sore or wound, commonly developing on the feet of people with diabetes.
  • Require moisture balance, infection control, and non-adhesive properties to protect fragile skin.

Bed Sores

  • Bed sores are ulcers which usually develop gradually on the skin and the tissue underneath. Occurring mostly in bed ridden patients, bed sores arise on the skin covering bony areas of the body such as hips, back, tailbone, etc.
  • Demand dressings that redistribute pressure and effectively manage exudate to prevent further skin breakdown.

Venous Leg Ulcers

  • Venous leg ulcers are chronic wounds affecting mostly older adults. They primarily result from prolonged venous insufficiency, which leads to tissue breakdown in lower extremities.
  • Benefit from a combination of compression therapy and absorbent dressings to address venous insufficiency and excessive fluid.

Infected Chronic Wounds

  • Chronic infected wounds are those wounds that do not even start to heal after 4 to 12 weeks despite treatment. They develop due to poor blood circulation, weak immune system or co-morbid conditions such as diabetes.
  • Require antimicrobial dressings to manage bacterial load and prevent further complications.

Key Dressing Options:

VEL NeXT™

  • Designed specifically for chronic wounds, including diabetic ulcers, burns, necrotizing fasciitis, and venous ulcers.
  • Promotes faster wound healing while maintaining an optimal moisture balance.

Velvert®

  • A secure antimicrobial dressing with excellent moisture management.
  • Ideal for wounds at high risk of infection, including diabetic ulcers and chronic wounds.

Silvel™

  • Features nano-crystalline silver for strong antimicrobial action.
  • Features silver for strong antimicrobial action.
  • Suitable for infected or high-risk wounds, particularly bed sores.

Velsap™

  • Designed for moderate to heavily exuding wounds.
  • Provides effective fluid management, reducing the need for frequent dressing changes.

How to Choose the Right Dressing?

Selecting the right dressing requires a comprehensive assessment of several factors:

  • Wound Type: Identify whether the wound is a diabetic ulcer, pressure sore, or venous ulcer.
  • Exudate Levels: Choose absorbent dressings for heavily exuding wounds and moisture-retaining options for dry wounds.
  • Infection Status: Use antimicrobial dressings for infected or high-risk wounds.
  • Patient-Specific Considerations: Factors such as mobility, skin sensitivity, and underlying health conditions must be considered.
Healthcare professionals play a crucial role in guiding dressing selection based on individual wound characteristics and patient needs.

Additional Tips for Chronic Wound Care Management

  • Proper Cleaning & Debridement: Keeping the wound clean and removing dead tissue enhances healing.
  • Regular Monitoring & Dressing Changes: Assessing the wound regularly and changing dressings at the right intervals prevent complications and ensure steady healing.

Chronic wounds require tailored solutions to support healing and prevent complications. Choosing the right dressing—ensures optimal wound care and faster recovery.

Wound during physical activity

Recovery doesn’t mean slowing down. Staying active while recovering from an injury or managing a wound doesn’t have to be an impossible task. With the right products and strategies, you can keep moving while ensuring that your recovery stays on track.

Whether you’re returning to your workout routine after surgery, dealing with an orthopedic injury, or healing a wound, we’ve got you covered.  Let’s dive into how you can integrate orthopedic and wound care products into your active lifestyle to keep you on the move and in the game.

The hidden risks of being active during recovery

Exercise helps circulation and mental health, but certain movements can disrupt healing. 
For wounds, bending, twisting, or sweating can weaken dressings and delay recovery.

EXAMPLE

Imagine a wound that’s healing well, but every time you move, the bandage loosens or moisture from sweat causes irritation. That can delay healing, reopen a wound, or even introduce bacteria. Similarly, orthopedic injuries like fractures or sprains require careful management to avoid strain that hinders healing.

The first rule of staying active during recovery?

Keep wounds protected during physical activity. The right products will shield your injury from friction, dirt, and moisture while allowing the skin to breathe. Opt for dressings that stay secure, comfortable, and irritation-free.

Our top products for Active Healing

When it comes to active recovery, we understand that you need products that work with you, not against you. That’s why we recommend products designed for ultimate support and flexibility.

  • Velpore™, Pressure-Sensitive Adhesive Tape:
    Hypoallergenic and breathable, it keeps dressings in place during physical activity without skin irritation.
  • Velfix® T+Pad, Waterproof Dressing:
    Ideal for post-surgical recovery, this waterproof dressing provides a bacterial barrier while you stay active.
  • Velfix® -T Film, Transparent Dressing:
    Clear, waterproof, and flexible, it offers protection while maintaining full range of motion.

When dealing with an orthopedic injury, immobilization is essential—but that doesn’t mean you have to sit on the sidelines.  Whether it’s a sprain, strain, or fracture, finding the right orthopedic product can help ensure that your recovery stays on track, even as you navigate through your day-to-day activities.

Hygiene: Clean up after movement

Excess sweat and dirt can compromise wound care. Velfix® -T+Pad helps manage moisture and ensures easy post-workout cleaning, preventing infection while maintaining healing.

While staying active is crucial, some exercises may be more beneficial than others during recovery. Low-impact activities like walking, swimming, or cycling can promote healing without overstraining your injury.

Recognize when to pause

Pay attention to swelling, redness, or increased pain after activity. If these occur, rest and assess—early intervention ensures faster recovery.

Holistic Healing: Rest & Nutrition

Healing requires proper rest and nutrition. A balanced diet, hydration, and enough sleep support tissue repair and overall recovery. Include vitamins, protein, and antioxidants to aid healing. Stay active and heal efficiently by using the right wound care and orthopedic products. With proper protection, hygiene, and mindful activity, your recovery journey can stay on track.
