What devices should the YY0500-2021 artificial blood vessel compliance tester include? Instruments should include: a) Instruments or methods for providing reproducible dynamic pressure within the blood vessel under the condition of fixed force (isobaric) or fixed length (isovolume) at 37°C ± 2°.
The testing instrument must be able to keep the sample temperature at 37℃±20C when testing the sample, YY 0500-2021/ISO 7198:1998 If a balloon is required, install the balloon as shown in Figure 10.The balloon should be at least 05 times the indicated dilated diameter at a pressure of 16 kPa (120 mmHg.
The balloon is to be mounted on a cylindrical mandrel not exceeding the maximum diameter of the mandrel (including the attached balloon.
.95 times the inner diameter of the blood vessel as defined in the natural state; b) pressure measurement devices, such as sensors, can measure the dynamic pressure range up to 27 kPa (200 mmHg) with an accuracy of 3 kPa (± 2 mmHg); c) The accuracy is +02mm diameter measuring device; d) The instrument can directly measure the change in diameter at multiple positions on the test sample or calculate the diameter of the blood vessel by measuring the intraluminal volume or diameter of the blood vessel; Note: For implantable biomaterials The resulting product, due to its inherent biological heterogeneity, is not suitable for the use of volumetric methods for determining complianc.
e) Distilled water should be used for testing, other methods may be used if justifie.
