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.

Ensuring Safe Wound Care Practices

Wound care is a critical aspect of healthcare that demands meticulous attention to patient safety. Proper wound management not only accelerates healing but also significantly reduces the risk of complications. In this blog, we will explore the importance of patient safety in wound care, emphasizing best practices, infection control, and risk minimization.

Importance of Patient Safety in Wound Care

Patient safety in wound care involves implementing measures to prevent harm and ensure safety during the treatment process. This includes avoiding infections, minimizing pain, and ensuring that wounds heal properly. A safe wound care environment is essential for patient well-being and can prevent further medical complications.

Best Practices in Wound Care

Assessment and Planning:

  • Thorough Assessment: Begin with a comprehensive assessment of the wound, considering factors like wound type, exudate characteristics, comorbid conditions, pain level, periwound condition, size, depth, and location. Understand the patient’s overall health, including any underlying conditions that may affect healing.
  • Individualized Care Plan: Develop a tailored care plan that addresses the specific needs of the patient and the wound. Regularly update the plan based on the wound’s progress.

Hygiene and Infection Control:

  • Clean Environment: Ensure the wound care area is clean and sanitized. All reusable wound care equipment and supplies should be sterilized before use. Fresh dressings and bandages should be cut with clean apparatus.
  • Hand Hygiene: Proper hand hygiene is crucial. Perform hand hygiene using alcohol-based rub or soap and water immediately before and after the wound care procedure. The use of gloves and other personal protective equipment (PPE) is mandatory to prevent contamination.

Wound Cleaning and Dressing:

  • Gentle Cleaning: Clean the wound gently with saline solution or appropriate antiseptic solutions. Avoid harsh scrubbing which can damage tissue and impede healing.
  • Appropriate Dressings: Use the right type of dressing for the wound such as hydrocolloid dressings for pressure ulcers or alginate dressings for heavily exuding wounds. Change dressings as per the doctor’s care plan to maintain a clean environment.

Patient Education and Involvement:

  • Educate Patients: Instruct patients and caregivers on proper wound care techniques, signs of infection, and when to seek medical advice. Patient education enhances compliance and promotes faster healing.

Infection Control:

Preventing infections is a cornerstone of safe wound care. Infections can complicate wound healing and lead to serious health issues. Implementing stringent infection control measures is essential.

  • Sterile Techniques: Always use sterile wound care equipment and supplies when handling wounds. This includes using sterile dressings, tools, and gloves.
  • Regular Monitoring: Monitor the wound for signs of infection, such as increased redness, swelling, warmth, or discharge. Early detection and intervention can prevent severe complications.
  • Antibiotic Use: Use antibiotics judiciously. Overuse or not finishing the full course of the antibiotic can lead to antibiotic resistance, making infections harder to treat.

Minimizing Risks:

Risk minimization in wound care involves anticipating potential problems and taking steps to avoid them.

  • Nutrition and Hydration: Ensure patients have adequate nutrition and hydration. A proper diet supports tissue repair and overall health.
  • Pressure Ulcer Prevention: For bedridden patients, repositioning is crucial to prevent pressure ulcers. Use pressure-relieving devices like specialized mattresses or cushions.
  • Moisture Control: Keep the wound environment moist but not wet. Moisture balance prevents the wound from drying out or becoming too wet, both of which can impede healing.

Ensuring safe wound care practices is vital for promoting patient recovery and preventing complications. By adhering to best practices, maintaining strict infection control, and actively involving patients in their care, healthcare professionals can create a safe and effective wound care environment. As we strive for excellence in wound care, let us remember that patient safety is at the heart of healing.

Adhering to international standards like ISO 9001:2015 and ISO 13485:2016 while manufacturing wound care products can further enhance the quality of wound care practices, ensuring that products meet rigorous safety and quality benchmarks. Let us commit to delivering next-gen healing solutions with a steadfast focus on safety and patient well-being.
