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.

Specific Considerations for Different Wounds

When it comes to wound care, one size does not fit all. Each wound has its own unique characteristics and possible complications. Tailoring first aid steps to specific types of injuries can significantly impact healing outcomes and minimize complications.

In this blog post, we look at different wounds with specific considerations emphasising the need for individualised care and additional precautions to enhance better results.

Understanding Different Wounds:

1. Burns:

First-degree burns: These affect only the outer layer of skin, causing redness and mild pain. Immediate first aid involves cooling the burn with cold water or a clean, damp cloth and then applying aloe vera gel. Cover the burn area with a sterile non stick bandage, this will help protect the damaged area from contaminants and the sun. 

Second-degree burns: These penetrate deeper into the skin, going through the first and second layer of the skin, causing blistering and severe pain. First aid includes cooling the burn, covering it loosely with a sterile gauze bandage, and seeking medical attention.

Third-degree burns: These are the most severe, affecting all layers of the skin and potentially deeper tissues. Third degree burns should always be treated by a healthcare provider and never at home. First aid involves not removing any clothing stuck to the burn, covering it with a clean, dry cloth, and seeking emergency medical help immediately.

2. Deep Cuts:

2a. Apply pressure: Use a sterile gauze pad or clean cloth to apply firm pressure to stop bleeding.
2b. Clean the wound: Once the bleeding has stopped rinse the cut with clean water to remove any debris and dirt.
2c. Bandage the wound: Once it has been cleaned properly, cover the cut with a sterile bandage or gauze pad and secure it with medical tape.
2d. Seek medical attention: Deep cuts may require stitches to promote proper healing and reduce the risk of infection.

3. Abrasions:
Abrasions, also known as scrapes, occur when the skin is rubbed or scraped against a rough surface, causing superficial damage.

3a. First aid involves cleaning the abrasion with soap and water to remove debris and applying an antibiotic ointment to prevent infection.
3b. Cover the abrasion with a sterile bandage or gauze pad to protect it from further irritation and promote healing.
3c. Change the dressing on a regular basis and check the area daily
3d. If there are any signs of an infection such as, fever, swelling, an increase in redness or fluid seek medical help from a healthcare provider.

4. Puncture Wounds: 
Puncture wounds are caused by sharp objects piercing the skin, such as nails, needles, or animal bites. Such types of wounds have a greater risk of infection as bacteria are being pushed into the skin.

4a. First aid involves cleaning the wound thoroughly with soap and water to remove any dirt or debris.
4b. Do not attempt to remove any object embedded in the skin. Instead, stabilize the object and seek medical attention immediately.
4c. Cover the puncture wound with a clean cloth or sterile bandage to reduce the risk of infection until medical help arrives.

Therefore, understanding the characteristics and appropriate first aid measures for different types of wounds is essential for providing effective care and promoting optimal healing outcomes.

Tailored First Aid:

Children:
a. Children’s skin is more delicate and prone to infection. Use extra caution when cleaning and bandaging wounds.
b. Consider using adhesive bandages with fun designs to make the first aid process less intimidating for children.

Elderly:
a. Elderly individuals may have thinner skin and reduced circulation, making them more susceptible to skin tears and slow wound healing.
b. Be gentle when cleaning and bandaging wounds to avoid causing further damage.

Individuals with Diabetes:
a. Diabetes can impair blood flow and reduce sensation in the extremities, increasing the risk of foot ulcers and slow-healing wounds.
b. Inspect feet daily for any signs of injury and seek prompt medical attention for any cuts or sores.

Precautions and Practices – 
In addition to first aid measures designed for specific wound types, there are several precautions and practices to keep in mind:

1. Always wash your hands thoroughly before and after your first treatment to prevent the spread of infection.
2. Use disposable gloves when treating the wound to reduce the risk of contamination.
3. Avoid using alcohol or hydrogen peroxide directly on the wound, as it can damage healthy tissue.
4. Keep first aid kits safe and easily accessible in an emergency.

Tailoring first aid measures to specific types of wounds is crucial for effective treatment and optimal healing. Whether it’s a minor burn or a deep cut, understanding the unique needs of each injury and taking appropriate action can make a significant difference in recovery outcomes and help in reducing the risk of complications.

In moments of crisis, such as accidents or emergencies, being equipped with the knowledge and skills to administer proper wound care can make a critical difference in saving lives and preventing further complications.

Whether you’re a bystander or the injured person themselves, understanding the essential steps of wound care in emergency situations is paramount. 

Here are some quick response tips to guide you through assessing and managing wounds effectively:

Assessment and Safety First:
The foremost priority in any emergency situation is safety. Before rushing to aid the injured person, take a moment to assess the surroundings for potential hazards. Ensure both your safety and that of the injured individual by identifying and eliminating any immediate dangers.

Control Bleeding:
One of the most crucial steps in wound care is controlling bleeding. Apply direct pressure to the wound using a clean cloth or dressing. Elevating the injured area, if feasible, can help reduce blood flow and minimize bleeding. Prompt action in staunching the blood flow can prevent further loss and stabilize the individual’s condition.

Clean the Wound Quickly:
After addressing the bleeding, it’s essential to clean the wound promptly. Rinse the wound gently with clean water to remove any debris or foreign objects. In emergency situations, it’s advisable to avoid using strong antiseptics or solutions unless absolutely necessary, as they can cause further irritation or delay in treatment.

Apply Dressing and Bandage:
Once the wound is cleaned, cover it with a sterile dressing or a clean cloth to protect it from contamination. Secure the dressing in place using a bandage or cloth, ensuring it is snug but not too tight to impede circulation. Proper dressings help create an optimal environment for wound healing while preventing infection.

Seek Medical Assistance:
While initial wound care is essential, it’s crucial to recognize the severity of the injury and seek professional medical assistance promptly. Call emergency services or transport the individual to the nearest medical facility if the wound is severe, deep, or if bleeding persists despite initial measures. Timely medical intervention can prevent complications and facilitate proper wound management.

Prevent Shock and Comfort the Injured:
In addition to physical care, it’s vital to address the emotional and psychological needs of the injured person. Keep them calm and reassured to prevent shock, covering them with a blanket to maintain body warmth and comfort. Offering words of encouragement and support can go a long way in alleviating distress.

Continued Monitoring and Updates:
Even after administering initial first aid, it’s essential to continue monitoring the injured person’s condition until professional help arrives. Stay vigilant for any signs of deterioration or changes in vital signs, providing updates and relevant information to emergency responders upon their arrival. Your ongoing support and assistance can contribute significantly to the individual’s overall well-being and recovery.

Therefore, effective wound care in emergency situations requires a combination of swift action, sound judgment, and compassion. By prioritizing safety, controlling bleeding, cleaning the wound, seeking medical assistance, providing comfort, and monitoring the individual’s condition, you can help ensure the best possible outcome for the injured person. Remember, every second counts in an emergency, and your actions can make a lifesaving difference.
