Embodiment Construction
[0087] like figure 1 -As shown in Fig. 6, the surface of the blood pressure measuring instrument is an inclined surface 20, and the mercury column box 1 is obliquely arranged in the blood pressure measuring instrument along the direction of the inclined surface; the bottom of the mercury column box 1 is connected to the bottom of the mercury tank 38 through a pipeline, in the The mercury control valve 36 is set on the pipeline, and the top of the mercury column box 1 communicates with the soft bag II 23 filled with protective gas (such as nitrogen or inert gas, etc.); In communication, the intake pipe I35 is connected to the mercury tank 38 through a pipeline, and an inflation control valve 33 is set on the pipeline. The circuit of the cuff is connected to one end of the air discharge pipe I59 through the air inlet (exhaust) port 8, and the air discharge pipe I59 is provided with an air discharge port I28; the mercury column box 1 is arranged on the mercury column box balance ...

The invention relates to the field of medical measurement instruments, in particular to a classic blood pressure measurement instrument. Limitations of an existing full-automatic electronic blood pressure meter are completely broken, and problems of measurement distortion and the like caused by the fact that mercury of a mercury column blood pressure meter is prone to oxidization, evaporation and leakage are effectively solved. The surface of the blood pressure measurement instrument is inclined, and a mercury column is arranged in the blood pressure measurement instrument along the inclined surface in an inclined mode. The bottom of the mercury column is connected with the bottom of a mercury groove through a pipeline, a mercury control valve is arranged on the pipeline, and the top portion of the mercury column is communicated with a soft bag which contains protective gas. An air pump is communicated with a sleeve belt through an air inlet pipe and an air inlet and outlet, and the air inlet pipe is connected with the mercury groove through the pipeline. The gravity of the mercury column in a mercury column box acts on a contact face of an air outlet, and pressure is produced. With the cooperation of a spherical protrusion, open and close of the air outlet enable the pressure in the sleeve belt to be balanced with the pressure produced by the mercury column, and a blood pressure measurement system of the sleeve belt to a brachial artery is formed in the instrument.
Description
technical field [0001] The invention relates to the field of medical measuring instruments, in particular to a blood pressure measuring instrument. Background technique [0002] Traditional sphygmomanometers include mercury sphygmomanometers and mechanical sphygmomanometers: mercury sphygmomanometers measure blood pressure based on the height of the mercury column corresponding to the Korotkoff sound, and mechanical sphygmomanometers measure blood pressure based on the needle indications corresponding to the Korotkoff sound. When using these two sphygmomanometers, always pay attention to picking up the Korotkoff sound from the stethoscope and visually watching the mercury column or pressure gauge to read the blood pressure value. The advantage is that the blood pressure measurement is more accurate. [0003] On the market, there are also semi-automatic electronic digital display blood pressure measuring instruments and fully automatic electronic digital display blood pressur...
