Arm sphygmomanometer internal capsule refers to the air pocket in the cuff of the sphygmomanometer, usually made of rubber or polyester material. It is an important part of measuring human blood pressure, ensuring the accuracy and reliability of the measurement results by providing pressure and support.
The main structure of the inner capsule includes the air bag, the valve and the connecting pipe. In use, the cuff will be placed over the upper arm, and a manual or automatic pump will pump air into the inner pocket to inflate it. When the bag is inflated to a certain pressure, the valve automatically closes, and the pressure in the cuff prevents blood from flowing through the arteries. Health care workers can use a stethoscope or digital display to read blood pressure.
The material and structure of the internal capsule play an important role in the accuracy and reliability of the sphygmomanometer. High quality inner capsules are usually made of high quality rubber or polyester materials and undergo a rigorous quality control and testing process to ensure their stability and durability.
Although the internal capsule of the arm cylinder sphygmomanometer is an important part of the device, it is also a wearing part. Long-term use and improper maintenance may lead to air bag rupture or leakage, which can affect the accuracy of blood pressure measurement. Therefore, users are advised to fold or roll up the cuff after use to reduce pressure and friction on the inner sac to extend its service life. At the same time, the internal capsule should be replaced regularly to maintain the accuracy and reliability of the sphygmomanometer.
