Diamond Blood Pressure monitor Clock model (BPDL 237)

The Diamond Blood Pressure Monitor Clock Model (BPDL 237) is a manual auscultatory sphygmomanometer designed for precise blood pressure measurement. This device utilizes a stethoscope for listening to Korotkoff sounds, enabling healthcare professionals to determine systolic and diastolic pressures. The instrument features a prominent, large-format analog dial for clear display of pressure readings, facilitating ease of use in various clinical settings.

Its construction incorporates durable materials intended to ensure consistent performance and longevity, making it suitable for frequent use. The monitor is designed for manual inflation and deflation, providing direct control over the measurement process. The unit of measurement is millimeters of mercury (mm Hg), with a resolution of 2 mm Hg and a pressure display range from 0 to 300 mm Hg.

The accuracy of the pressure reading is within +/- 4 mm Hg.

The operational principle of the Diamond Blood Pressure Monitor relies on the auscultatory method. A cuff, sized at 14.5 cm x 51 cm, is applied to the patient's limb and inflated manually using a rubber bulb.

As the cuff pressure is gradually released via a handheld control valve, the healthcare provider listens for specific arterial sounds with a stethoscope. The pressure indicated on the dial when the first sound is heard is the systolic pressure, and the pressure at which the sounds disappear is the diastolic pressure. The device's internal mechanism is engineered for repeatable and accurate readings.

Key features of this blood pressure monitor include its large, 6x6 inch square dial, which offers enhanced visibility from a distance, and a high-contrast background for quick and clear interpretation of readings. The inclusion of a special ‘D’ ring cuff, a durable control valve, bladder, and bulb contributes to both user comfort and reliable performance. The bellows are constructed from materials selected for their durability and consistent accuracy.

The design also incorporates a tiltable faceplate, allowing for optimal viewing angles, and coiled, expandable tubing for flexible positioning during use. All plastic and rubber components are made from medical-grade virgin material, and the metal parts are corrosion-resistant, contributing to the device's overall robustness and extended service life.

This blood pressure monitor is intended for use by medical professionals, including physicians, nurses, and medical technicians, in settings such as hospitals, clinics, and private practices. It can also be utilized by trained caregivers in home healthcare environments. The device is suitable for routine blood pressure monitoring of adult patients.

Typical applications include pre-operative assessments, post-operative monitoring, chronic disease management, and general health check-ups. Its manual operation requires a degree of clinical skill and knowledge of auscultatory techniques.

Important usage notes include ensuring the cuff is correctly applied to the patient's arm and inflated to an appropriate level. Deflation should be controlled at a rate of approximately 2-3 mm Hg per second to ensure accurate detection of Korotkoff sounds. The device should be handled with care to prevent damage and stored in a cool, dry environment.

It is crucial to inspect the monitor for any signs of damage before each use. This device is intended for use with a stethoscope, which is typically supplied separately. The integrity of the rubber bulb and control valve should be maintained for proper inflation and deflation.
