Abstract
The invention discloses a rising type sphygmomanometer, which comprises a wristband and a gas circuit body (2) connected with the wristband. The rising type sphygmomanometer is characterized in that the gas circuit body (2) comprises a main airflow channel (4); the main airflow channel (4) comprises a first end part (6) connected with the wristband, a second end part (8) connected with an air capacitor (7), an air inlet (9) positioned on the main airflow channel (4), and an air outlet (16) positioned on the main airflow channel (4); the air outlet (16) is also connected with an air outlet pipe (19) which is vertical to the main airflow channel (4). An air pump (14) and a pressure sensor (10) are staggered to effectively avoid impact on the pressure sensor (10) by the air pump (14). In addition, the air capacitor (7) is arranged before the pressure sensor (10) is arranged so as to perform a good buffer function.
Description
Technical field
The present invention relates to a kind of ascending manner sphygomanometer.
Background technology
Electric sphygmomanometer adopts sensor acquisition pulse signal, measures high pressure, low voltage value, highly sensitive, and its work is not disturbed by factors such as external sounds；Electric sphygmomanometer is based on vibratory drilling method.In the process increasing or reducing static pressure, extracting, amplify pulsation pressure and describe its envelope, then the geometric shape of envelope is analyzed, the static pressure corresponding to envelope peak is mean pressure.By ratio method or bathmometry estimation diastolic pressure and pressure is shunk by mean pressure.
First cuff is bundled on arm, to cuff automatic inflating, pressurization is stopped afterwards to certain pressure (generally exceeding 30～50mmHg than contraction pressure), start venting, when air pressure to a certain extent, blood flow just can pass through blood vessel, and has certain wave of oscillation, the wave of oscillation propagates pressure transducer by trachea, and pressure sensing can detect the pressure in surveyed cuff and fluctuation in real time.Exitting gradually, the wave of oscillation is increasing.Exitting owing to cuff is more loose with contacting of arm, pressure and fluctuation that therefore pressure transducer detects are more and more less again.Selecting the fluctuation maximum moment is reference point, and based on this point, searching is the fluctuation point of peak value 0.45 forward, this point is for shrinking pressure, searching is the fluctuation point of peak value 0.75 backward, and the pressure corresponding to this point is diastolic pressure, and the highest pressure corresponding to point that fluctuates is mean pressure.It is worth mentioning that 0.45 and 0.75 this constant.
Sensor and pump are oppositely arranged by general sphygomanometer on the market, and sensor is had very big impact by pump, thus affecting the accuracy of sensor result.
Summary of the invention
It is an object of the invention to provide and a kind of can reduce the pump surging device to the interference of collecting sensor signal.
For solving the problems referred to above, the invention provides a kind of ascending manner sphygomanometer, including cuff and the gas circuit main body that is connected with described cuff, it is characterised in that described gas circuit main body includes main air flow passage, and described main air flow passage includes:
The first end being connected with described cuff；
The second end being connected with air-capacitor, described air-capacitor is connected to the pressure transducer being able to detect that Sasser；
Being positioned at the air inlet on described main air flow passage, described air inlet is through hole, and it is connected with air pump by air inlet pipe, and the angle between described air inlet pipe and described main air flow passage is acute angle or obtuse angle；
Being positioned at the gas vent on described main air flow passage, described gas vent is through hole and is positioned on same level line with described air inlet, and described gas vent is also associated with escape pipe, and described escape pipe is vertical with described main air flow passage.
As a further improvement on the present invention, described air-capacitor inner chamber is divided into several chambers by partition, by being arranged on the hole connection on described partition between described chamber.
The beneficial effects of the present invention is, the present invention, by angled to pump and sensor setting, effectively prevent the pump impact to sensor, is additionally provided on before sensor and arranges air-capacitor, and gas plays a good cushioning effect.
