Non-aspirating dispenser for thixotropic gel delivery
A recently granted patent (Publication Number: US11926467B2) describes an ergonomic-friendly non-aspirating dispenser designed for ejecting a thixotropic gel. The dispenser comprises a container with a single opening sealed by a valve, housing a flexible bag containing the gel with a specific viscosity range. The internal volume of the container includes the initial bag volume and a non-bag volume filled with gas at a certain pressure, without any propellant or volatile liquid. An actuator connected to the valve allows the gas to force the gel out in non-aspirated droplets of a defined mean volume diameter, eliminating the need for an aspirator.
The patented dispenser, as outlined in the claims, is tailored for applying thixotropic gels containing various substances like cellulose, guar gum, and alginate to medical articles. The mean volume diameter of the dispensed droplets falls within a specific range, ensuring precise application. The flexible bag's volume within the container is optimized to enhance the dispensing process, with the pressurized gas comprising air, carbon dioxide, or nitrogen. The design of the dispenser prioritizes ergonomic considerations and efficient gel delivery, making it a valuable tool for medical applications requiring controlled and accurate gel application processes.
