Coriolis pneumatic analog audio and digital electronic sphygmomanometer was used to test


Available ten years, as the ship split on m per year, ten years after the replacement of the table should be. If the selection of capture range, high degree of precision difficult to do tables on the very economic. Some may be obvious from the above to see Oh, precision meter testing general pressure gauges, with the range it is feasible to select the table to catch both accurate and reasonable, fork economical and practical, but also closer to the international recommendations. (Pa City Bureau of Standards and Metrology Bo Wang sets) with pneumatic analog audio is used to test the Coriolis digital electronic sphygmomanometer Guifu Pavilion 'Kip West Province, Institute of Measurement and Testing) This paper describes the digital electronic blood pressure monitor on my take of the systolic and diastolic blood pressure meter,[link widoczny dla zalogowanych], and ignorant of the dates indicated value of the dynamic performance, with the situation. Highlights such as the servo pneumatic analog audio and digital Coriolis electronic device installed in the spy case by the Xinjiang (KorothoffSounds) was used to test digital electronic blood pressure, systolic or diastolic blood pressure resistive sensor to collect, use microcomputer control [livestock) Measurement Technology 199i7 sets installed in the arm (or not set in the arm) of the measuring device to identify the Coriolis sound audio to digital display of human values and systolic and diastolic blood pressure pulse rate number. It is the measurement of human blood pressure of advanced equipment, mercury pollution, and easy self-testing,[link widoczny dla zalogowanych], applications have been very popular in foreign countries. In recent years, an increasing number of users also. However, in the course of the inaccurate measurement of the phenomenon found in more, thus requiring measurement department as soon as possible to carry out the compulsory certification program. Digital electronic blood pressure monitor to ensure the overall performance, the need for the systolic and diastolic blood pressure and pulse rate of the dynamic testing. However, the electro-acoustic simulation of the Coriolis measuring tone method applies only in the arm damper set of digital electronic sphygmomanometer comprising the dynamic test, and for measuring damper placed in the chassis of the digital electronic sphygmomanometer dynamic tests not be achieved. However, this type of digital electronic devices behind the difficulties of its simple operation, anti-jamming performance, has become the production of digital electronic blood pressure monitor the mainstream of development. Therefore, we must find both a damper for measuring kit home in the arm, but also for measuring damper placed in the chassis of the digital electronic blood pressure monitor dynamic performance testing of new methods. We can not copy foreign approaches use a dedicated computer system, because the high prices of such systems, maintenance, operation complicated. After extensive in-depth investigation and trial and error, has developed a new method in line with our national conditions and the Coriolis sound of a pneumatic analog method. Simulation of the advent of the Coriolis tone generator, so that the Coriolis pneumatic analog audio and digital electronic blood pressure monitor detected the dynamic performance of a reality. Aerodynamic Simulation Division's method is the analog audio tone generator as the Coriolis and test equipment used in the standard blood pressure monitor connected, constitute the verification of digital electronic blood pressure device. 1. Will be used in the standard blood pressure test, was shuttle digital and analog electronic devices such as the Coriolis tone generator, with the medical hose connection, such as the schematic diagram, a tone generator, the analog Coriolis; 2 for standard devices: 3 said tee; 4, said automatic release valve; 5, said rubber ball; 6 shows that arms were seized with a period of 7; 8 said poles; 9, said thin latex tube; 10,[link widoczny dla zalogowanych], said that the intake pipe tee j11} 12 said Tone control. 2. Will be seized digital electronic sphygmomanometer deflated http compression ball and take down, press the circle access verification devices. 3. Before the test chamber through the atmosphere to arm bands. Indication at this time should be 0.0 or 0.1kPa4. Pressurized to 32kPa or more, and then let the verification device automatically deflated blood pressure,[link widoczny dla zalogowanych], while observing the standards of the Pressure indication, when the standard control systolic blood pressure indication down to test point, click the analog sound generator Coriolis start / Stop button to start the simulation of Coriolis tone generator; Pressure indication when the standard diastolic blood pressure check points down, and then click sound generator Coriolis simulation start / stop button to close the analog tone generator Coriolis records were subsequently check blood pressure and the test points shown in the corresponding systolic and diastolic blood pressure indication. 4 during the same time, records were seized blood pressure pulse rate indication. 5. Systolic blood pressure test point: 28kPa, 22kPa, 16kPa ~ corresponding to the diastolic blood pressure test points; 20kPa, 14kPa, 8kPa. Finally, the measured data processing,[link widoczny dla zalogowanych], and in accordance with the requirements of accuracy level, blood pressure was seized to determine eligibility. (Continued from page 1 to do a bit of distortion produced several sets of experimental data measured at different frequencies as shown in Table 1. Fundamental frequency is 20Hz, harmonic ripple components superimposed by the second harmonic transition, different distortion measured data such as an empty table 2. Base transition frequency 50Hz, the third harmonic superposition '-. -. ~ ~ One by one when the distortion wave data measured in Table 3. From the above analysis and experimental data can be seen that the amount needed guillotine when the peak to peak sinusoidal signal, pure sine wave if the crest factor converter with a sine wave distortion, in the worst case, the distortion Zhu K <when , about the introduction of j (measurement error.
