Diamond Dial Deluxe Blood Pressure Apparatus With Field Calibration

The Diamond Dial Deluxe Blood Pressure Apparatus With Field Calibration is a sphygmomanometer designed for the measurement of arterial blood pressure. This device incorporates a unique field calibration capability, allowing for on-site adjustments to ensure the accuracy of its readings under varying environmental conditions. The apparatus is comprised of several key components: an inflatable cuff designed to encircle the patient's limb, a pressure gauge featuring a dial for visual monitoring and manual adjustment, and a hand pump used to inflate the cuff.

The integrated field calibration mechanism allows healthcare professionals to fine-tune the gauge's accuracy directly in the clinical setting, eliminating the need for external calibration equipment for routine adjustments.

The operational principle of this sphygmomanometer involves the inflation of the cuff around the patient's arm to a pressure sufficient to occlude arterial blood flow. As the pressure is gradually released by deflating the cuff, the user listens for Korotkoff sounds using a stethoscope (not included). The pressure indicated on the dial when the first sounds are heard corresponds to the systolic blood pressure, and the pressure at which the sounds disappear is the diastolic blood pressure.

The field calibration feature is crucial for maintaining the device's precision over time and across different usage environments. The dial features a scale ranging from 20 to 300 mmHg with a resolution of 2 mmHg, providing detailed readings.

Key features and benefits of this blood pressure apparatus include its capacity for accurate blood pressure monitoring due to the field calibration function. The construction utilizes medical-grade materials, contributing to its durability and suitability for clinical use. The metal components are treated with nickel and chromium plating to enhance resistance to corrosion, prolonging the lifespan of the instrument.

A specialized velcro cuff is included to facilitate a secure and effective grip during application. The design and functionality are recognized for their utility by visiting medical practitioners.

This device is intended for use by trained medical professionals, including physicians, nurses, and other healthcare providers, in various clinical settings. It can also be utilized by trained caregivers in home healthcare environments. The primary application is the non-invasive measurement of systolic and diastolic blood pressure in adult patients.

Typical settings include physician offices, hospitals, clinics, and long-term care facilities. The ability to perform field calibration makes it particularly useful for mobile healthcare units or in locations where regular access to laboratory calibration services may be limited.

Important usage notes include ensuring the cuff is applied correctly to the patient's limb, typically the upper arm, at heart level. The inflation and deflation rates should be controlled to obtain accurate readings. Users should familiarize themselves with the field calibration procedure to maintain the device's accuracy.

The apparatus should be handled with care to prevent damage and stored in a cool, dry environment when not in use. It is advised not to use the device if the packaging appears damaged. This instrument is designed for use by adults and should be kept out of reach of children.
