1 Scope

The order applies to (desktop and vertical) mercury sphygmomanometer (hereinafter referred to as sphygmomanometer) and elastic blood pressure table (to Hereinafter referred to as blood pressure table) initial verification, subsequent verification and in-service inspection.

2 Overview

Sphygmomanometer blood pressure table and the hospital or home blood pressure was observed using the indirect method of measuring instruments. Sphygmomanometer working principle is based on the principle of hydrostatic equilibrium, by the communication unit of the mercury reservoir bottle and the indication tube communicating, when After the mercury storage bottle mercury surface pressure, forcing indication within the mercury rises indicating that the pressure value. Blood pressure table is based on Hooke's law is made, the working principle is tested under pressure, forcing the elastic sensing element (Elastic film cartridge) with a corresponding elastic deformation --- displacement, by means of a connecting rod, shaft drive through a gear transmission mechanism And is amplified by the fixed gear shaft pointer gradually measured pressure value indicated on the index plate.

3 metering performance requirements

3.1 zero error 3.1.1 mercury sphygmomanometer reservoir bottle and the atmosphere, mercury readings should be at the top surface and the zero scale line tangent bits Home, a tolerance of. -0.2kPa ~ 0.5kPa (-1.5mmHg ~ 3.75mmHg). After the elastic sensing element 3.1.2 blood pressure meter lumen with the atmosphere, the pointer should be in the zero mark. 3.2 sphygmomanometer sensitivity When the mercury in the rapid decline in the sudden pause, the volatility of not less than 0.3kPa (2.25mmHg). 3.3 tightness 3.3.1 rubber ball valve knob on tightening should not leak, unscrew should not fall off; return valve should stop for gas use. 3.3.2 sphygmomanometer, blood pressure table in 1min pressure drop. the first test should not exceed 0.5kPa (3.75mmHg), Subsequent in-service inspection and verification should not exceed 0.8kPa (6mmHg); mercury sphygmomanometer bottle storage not leak mercury, mercury Column may not have turned bubble phenomenon. 3.4 Indication error Indication sphygmomanometer, blood pressure table are the maximum permissible error. ± 0.5kPa (± 3.75mmHg). 3.5 blood pressure table pointer deflection stability Blood pressure table pointer deflection should be stable and should not be beating and stagnation.

4 General technical requirements

4.1 Appearance 4.1.1 sphygmomanometer, blood pressure meter housing should be sturdy, and protects the internal components from damage and not be defiled. 4.1.2 newly manufactured sphygmomanometer, blood pressure meter housing coating gloss coating should be uniform, no obvious stripping phenomenon.
