本文主要介绍用于动物生态血压监测的直接式示波电子血压计的装置、测压方法和使用价值。除概述仪器的基本结构外,还讨论了系统的频响问题,提供了装置的原理电路,并提出了对显示记录系统的要求。仪器结构轻小,手术后可将换能器固定于手术部位附近,在肝素的配用下,可在自然状态下测压。测压时,使用方便,将换能器的插头插入主机插口中即可。仪器的灵敏度高,抗噪声能力强,其所测波形,与 Wiggers 所测波形对比,血压波形的各小波均显示清晰。
This article describes the device for direct oscillometric blood pressure monitor for animal blood pressure monitoring, pressure measurement method and value. In addition to an overview of the basic structure of the instrument, the frequency response of the system is also discussed. The principle circuit of the device is provided and the requirements for the display recording system are presented. Instrument structure is light, the transducer can be fixed after surgery in the vicinity of the surgical site, with the use of heparin, in the natural state of manometry. Manometry, easy to use, the transducer plug into the host socket can be. Instrument sensitivity, anti-noise ability, the measured waveform, compared with the Wiggers measured waveforms, the blood pressure waveforms of the waveforms are clear.
