Final answer:
The sphygmomanometer is a medical device used to measure blood pressure. It consists of several components, including a compression cuff, pressure bulb, diaphragm, and pressure control valve. The component that is not a part of the sphygmomanometer is the pressure control valve.
Step-by-step explanation:
The sphygmomanometer is a medical device used to measure blood pressure. It consists of several components, including:
- Compression cuff: This is the part of the sphygmomanometer that is wrapped around the upper arm to restrict blood flow.
- Pressure bulb: This is a rubber bulb that is squeezed to inflate the cuff and apply pressure to the arm.
- Diaphragm: The diaphragm is a part of the sphygmomanometer that measures the pressure. It is located on the cuff and detects the pulsations of blood flow.
- Pressure control valve: This valve is used to release the pressure in the cuff gradually.
Out of the given options, the component that is not a part of the sphygmomanometer is the Pressure control valve.
