DIAMOND B.P. BULB

DESCRIPTION

If you’re looking at a Diamond B.P. Bulb, you’re likely dealing with a component for a manual aneroid or mercury sphygmomanometer (blood pressure monitor). Diamond is a well-known brand, particularly in South Asia, recognized for durable diagnostic equipment.

Here is a breakdown of the description and features of a standard Diamond B.P. inflation bulb.

 Physical Description

The bulb is the handheld pump used to inflate the cuff. Its design focuses on ergonomics and air-flow control.

• Material: Usually made of high-quality natural rubber or synthetic latex-free material. It’s designed to be supple enough for easy squeezing but thick enough to prevent cracking.

• Shape: An oval, teardrop, or “egg” shape that fits comfortably in the palm of the hand.

• Color: Typically classic black, though some clinical versions come in grey.

 Key Components

A Diamond B.P. bulb isn’t just a piece of rubber; it’s a two-way valve system:

1. The Rear Valve (Inlet): A small metal or plastic check valve at the bottom. It allows air to enter the bulb when you release your grip but prevents air from escaping back out when you squeeze.

2. The Control Valve (Air Release): This is the chrome-plated metal knob at the top.

   • Function: It features a precision-threaded screw that allows for “controlled deflation.”

   • The “Diamond” Touch: Their valves are known for having a smooth “drop” rate, meaning you can bleed the air out at the recommended 2–3 mmHg per second without the valve sticking or jumping.

     Common Use Cases

     • Replacement Part: Because rubber degrades over time (becoming brittle or sticky), these are frequently sold as individual replacement parts for doctors’ offices.

     • Customization: Some practitioners prefer the Diamond bulb because the metal valve is often more durable than the plastic ones found on cheaper, generic kits.
