Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a convenient and detachable non-invasive blood pressure measuring instrument. Background Art

[0002] Compared with peripheral arterial blood pressure, central arterial pressure can better reflect the blood pressure load of the human cardiovascular system, and the central arterial pressure index is more accurate in predicting cardiovascular disease. The difference in the efficacy of different antihypertensive drugs may be due to the different effects of lowering central arterial pressure. Therefore, central arterial pressure may have clinical value that cannot be replaced by peripheral arterial pressure.

[0003] The most accurate method for measuring central arterial pressure is the catheter method, but this method is an invasive examination and has high requirements for equipment and measurement, so it is difficult to popularize in clinical practice. At present, the research on central arterial pressure detection is mainly focused on non-invasive detection methods. The core idea of ​​non-invasive detection methods is to estimate central arterial pressure through non-invasively detectable signs and the relationship between these signs and central arterial pressure, so this requires the use of non-invasive blood pressure meters.

[0004] However, the existing non-invasive blood pressure measuring instruments are not easy to disassemble and maintain after being assembled as a whole, which brings certain inconveniences to the disassembly and maintenance when a fault occurs. In addition, the multiple connection sockets on the measuring instrument are all externally designed, and there is no effective protective cover structure. Therefore, dust and debris are easily attached to contaminate and clog the sockets. Therefore, we propose a non-invasive blood pressure measuring instrument that is convenient to disassemble and assemble. Utility Model Content
