The duckbill valve is a type of check valve that is commonly used in medical applications. It is made from rubber or synthetic elastomer and has 2 flaps that resemble a duck’s beak. This type of valve prevents backflow and contamination of fluids. They are available in a variety of elastomeric materials and are easy to assemble.
Spectra Duckbill valves are designed to increase suction and provide better output during breast pumping sessions
The Spectra Duckbill valve set is a high-quality breast pumping accessory that is designed to enhance suction and output during breast pumping sessions. Its silicone construction prevents backflow and ensures proper suction. You should replace your duckbill valve every three months if you regularly pump. Do not place the valve in the dishwasher or sterilizer. Instead, hand wash it.
Spectra breast pumps come with different sizes of breast shields. You can choose between 24mm, 28mm, and 32mm. When choosing your shield, take into consideration the size of your nipple. If you find that your nipple is rubbing on the outer edge of the shield, you may want to select a larger breast shield.
Spectra breast pumps are designed with massage and expression modes. Most moms start their pumping sessions with massage mode to encourage milk release. You can then adjust the suction pressure to feel slight discomfort and increase it when you’re ready for a more intense session. When the milk drips, the duck bill check valve pump automatically switches to expression mode. Unlike most breast pumps, the Spectra pump also allows you to customize suction and cycle speed according to your needs.
They are easy to incorporate and assemble
A duckbill valve has a cylindrical body with curved reinforcing ribs, and a distal and a proximal end, separated by a cylindrical mid-section. These two ends are arranged to form a flange that cooperates with the receiving introducer housing to provide a resilient sealing surface. This seal prevents fluid from flowing around the outer surface of the valve.
A duckbill check valve is an excellent choice for backflow prevention. It has a high degree of flexibility and is resistant to corrosive materials, as well as suspended solids. Its elastomeric construction provides a watertight seal around suspended and trapped solids, and its outer layer is designed to repel marine organisms.
The side walls 40 a and 40 b of a duckbill valve have a symmetrically tapered outer wall with a slit extending through the center of each. The outer and inner walls of the second end have a non-uniformly rounded geometry, which biases the slit to close.
