Problems solved by technology

[0003] Invasive blood pressure testing equipment needs to be tested when leaving the factory or in use. The test device simulates blood pressure signals, including dynamic pressure signals and static pressure signals, while traditional invasive blood pressure testing devices can only simulate the blood system, and it is difficult to generate YY0781 and YY0783, etc. The hydraulic waveform required in the medical standards makes the existing invasive blood pressure testing devices unable to perform performance verification of blood pressure testing equipment according to the methods provided by medical standards such as YY0781 and YY0783

Embodiment Construction

[0032] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, these embodiments are provided to make the understanding of the disclosure of the present invention more thorough and comprehensive.

[0033] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as...

Abstract

The invention relates to an invasive blood pressure testing device which comprises a loop system adjustable in volume, a sensor system used for detecting pressure of a simulation medium in the loop system, a dynamic pressure adjusting system and a control system connected with the sensor system and used for controlling the dynamic pressure adjusting system. The control system can control the dynamic pressure adjusting system or a static pressure adjusting system to adjust volume of the loop system through hydraulic waveforms (including dynamic blood pressure waveforms and static blood pressure waveforms) required in pharmaceutical standards to cause changing of the pressure of the simulation medium in the loop system so as to output dynamic blood pressure or static blood pressure of an organism in a simulation manner, the sensor system monitors the pressure of the simulation medium in the loop system in real time and is connected with the control system, and the control system can output simulation dynamic or static blood pressure waveforms meeting the standards according to pressure data monitored in real time.

Description

technical field [0001] The invention relates to the field of medical equipment detection, in particular to an invasive blood pressure testing device. Background technique [0002] Blood pressure is one of the important parameters clinically used to detect human vital signs. Blood pressure measurement can be divided into non-invasive and invasive methods, of which invasive blood pressure measurement is recognized as a standard method. Invasive blood pressure measurement is suitable for expected applications requiring blood pressure monitoring such as surgical patients, intensive care patients and newborns, and has the characteristics of fast response time, accurate results, strong anti-interference and wide application range. Invasive blood pressure measurement, also known as direct blood pressure measurement, establishes a direct channel with the patient's measurement site, and transmits the blood pressure to an external pressure sensor by means of liquid communication to o...
