Before using the medical devices cuff pressure gauge, sufficient and standardized preparation is an important prerequisite to ensure accurate and reliable measurement results, which involves multiple links such as equipment inspection, environmental confirmation, and adjustment of the state of the measured person.
Inspection of the medical devices cuff pressure gauge itself is the primary task. First, carefully check the appearance of the cuff to confirm whether it has signs of damage, aging or leakage. If there are cracks or wear on the surface of the cuff, or the rubber material loses its elasticity, leakage may occur during measurement, resulting in the inability to maintain stable pressure, which in turn affects the measurement results. For mechanical pressure gauges, it is necessary to observe whether the pointer is flexible and whether it can accurately return to zero without external force. If the pointer is stuck or deviates from zero, it means that the mechanical structure inside the pressure gauge may be faulty and needs to be repaired or calibrated in time. For electronic pressure gauges, it is necessary to ensure that the power is sufficient and the display screen displays normally to avoid reading errors due to insufficient power or abnormal screen display.
The status of the connecting pipeline should not be ignored. It is necessary to check whether the connection between the pipeline and the pressure gauge and cuff is tight to ensure that there is no risk of loosening or falling off. At the same time, check whether the pipeline is bent, twisted or blocked. The bent pipeline will hinder the flow of gas, making the pressure transmission poor, resulting in the inability to inflate or deflate the cuff during measurement, affecting the accurate transmission and display of pressure. If there is a foreign object blocking the inside of the pipeline, it will also interfere with the flow of gas, making the value displayed by the pressure gauge inconsistent with the actual cuff pressure.
In addition to the equipment itself, the preparation of the measurement environment is also very important. A quiet, comfortable and temperature-appropriate space should be selected for measurement. A noisy environment will not only distract the measurement person's attention and affect the accuracy of the operation, but may also make the person being measured nervous and cause blood pressure fluctuations. Too high or too low temperature will cause the vasoconstriction reaction of the human body and interfere with the true blood pressure value. Therefore, it is particularly important to keep the indoor temperature in the human body's comfortable range. In addition, the measurement site should be well lit so that the pressure gauge reading can be clearly observed to avoid misreading due to dim light.
The preparation of the person being measured is equally important. Before measurement, the person being measured should be kept quiet for a period of time, and avoid measuring immediately after strenuous exercise, emotional excitement or drinking stimulating drinks. Because the heart pumps faster after exercise, the hormone levels in the body change when the mood fluctuates, and the stimulation of stimulating drinks on the cardiovascular system, blood pressure will temporarily rise and cannot reflect the true blood pressure condition. At the same time, inform the measured person of the precautions during the measurement process, such as keeping the arm relaxed, not talking, avoiding limb movements, etc., to reduce the interference of human factors on the measurement results.
The measurer himself also needs to be prepared. Before the operation, the measurer should wash his hands and keep his hands clean to avoid contaminating the cuff due to unclean hands. At the same time, you should be familiar with the operating procedures and performance characteristics of the medical devices cuff pressure gauge, and be familiar with the different operating methods and precautions of mechanical and electronic watches. In addition, the measurer should also maintain concentration and patience, treat each measurement with a rigorous attitude, and ensure that the operation is standardized and accurate.
For reusable cuffs, strict cleaning and disinfection must be carried out before use. The cuffs used for a long time will leave sweat, dandruff and other substances. If they are not cleaned in time, it will not only affect the service life of the cuff, but also become a breeding ground for bacteria, increasing the risk of cross infection. When disinfecting, it is necessary to choose the appropriate disinfectant and disinfection method to ensure that it can effectively kill germs without damaging the cuff material.
After everything is ready, a final review is required. Reconfirm whether the connection of the cuff, pipeline and pressure gauge is firm, check whether the posture of the person being measured is correct, and whether the arm position is at the same level as the heart. Only through comprehensive and meticulous preparation can the measurement error be minimized to the greatest extent, and true and reliable blood pressure data can be obtained, providing strong support for clinical diagnosis and health assessment.
