This is a one-way valve for ventilation on sphygmomanometer air pumps. It has an overall small black sheet-like structure. It looks almost rectangular.There are several specially designed hollowed-out areas on it.These areas use a "U"-shaped design or other irregular through-hole designs. The edges also have small holes.These holes are for installation and fixation.The valve has a compact and regular structure. The special hole layout is easy to see—it’s made just for the one-way ventilation function.Its overall design is compact and delicate.It fits the structure of sphygmomanometer air pumps.This makes installation easy.It also helps control ventilation effectively.It’s a critical airflow control part in medical devices.It helps meet the sealing and fluid management needs of Medical Device Seals and Respiratory and Related Equipment Accessories (for air pressure-based medical tools).
1. Function
The one-way valve for ventilation on sphygmomanometer air pumps mainly works to control the one-way flow of gas in the air pump.When the sphygmomanometer is inflating, it lets gas flow in one direction.Usually, that direction is toward the cuff.This lets the air pump inflate the cuff effectively.Then blood pressure can be measured. When inflation stops or deflation starts, it blocks gas from flowing backward.This keeps the air pressure inside the cuff stable.This makes sure blood pressure measurement is accurate.It also gives key airflow control support for getting precise blood pressure data.Its one-way control role matches the pressure stabilization requirements of Ventilator Parts and Breathing Equipment Gaskets in medical air pressure systems.
2. Required Characteristics
1)Precise One-Way ConductivityIt must strictly make sure gas flows only in one direction.It must reliably block reverse flow.There should be no air leakage or reverse ventilation.This is essential to make sure the sphygmomanometer air pump inflates correctly and keeps pressure stable.Then blood pressure measurement results are reliable.This precision meets the strict flow control standards of Medical Grade Silicone Seals and Sterile Medical Seals in medical fluid systems.
2)Excellent Sealing PerformanceNo matter if the valve is letting gas through or blocking it, the joint between the valve and the air pump (and related parts) must seal well.This stops gas from leaking through unintended gaps.Leaks would affect how well the air pump inflates and how stable the cuff pressure is.This meets the sealing specifications of Nebulizer Sealing Components and Respiratory Seals for medical air systems.
3)Medical-Grade SafetyIt’s made of materials that meet medical standards.These materials are non-toxic and non-irritating.When it touches gas or is used in medical environments, it doesn’t release harmful substances.This makes sure medical applications are safe.This safety attribute matches the material requirements of medical silicone seal and Medical Vial Cap Seals for medical devices.
4)Stable Physical PropertiesIt should have good wear resistance and anti-aging properties.During long-term use—like when the air pump inflates and deflates often—it can keep its shape, structure, and function stable.It won’t deform, crack, or have other issues easily.This makes sure it has a long service life and stays reliable.This stability meets the durability demands of Medical Device Seals and Breathing Equipment Gaskets in high-cycle medical use.
5)AdaptabilityIts size and structure must match the corresponding part of the sphygmomanometer air pump exactly.This makes installation easy.After installation, it should fit tightly. Then it can work well as a one-way valve.It avoids performance problems caused by wrong size or structure.This adaptability meets the assembly standards of Respiratory and Related Equipment Accessories and medical device components.
