Description

Technical Field

[0001] The utility model is applicable to the technical field of medical devices, and particularly relates to a heating device for assisting a mechanical force-mediated hemolysis test. Background Art

[0002] At present, mechanical force-mediated hemolysis refers to the distortion and rupture of red blood cell membranes caused by fluid dynamic factors such as blood flow rate, vortex, and non-physiological shear force. When the sample comes into contact with blood, hemolytic substances may cause red blood cell loss or damage, and may produce increased levels of free plasma hemoglobin, thereby inducing toxic effects or other effects, which may cause stress to the kidneys or other organs. Hemolysis is considered an important screening test because increased plasma hemoglobin levels in the body are abnormal and may be an indication of potential blood pathology or vascular problems. In the research and development stage of medical devices, the results of mechanical force-mediated hemolysis tests are very important. Through mechanical force-mediated hemolysis tests, it can be preliminarily determined whether the material has mechanical force-mediated hemolysis, and then some hidden dangers in the patient's body can be detected and screened.

[0003] However, the current mechanical force-mediated hemolysis test circuit consists of a 2-meter-long hollow tube with an inner diameter of 9.5 mm and a blood bag. The blood bag is equipped with a sampling port or a tee with a three-way outlet, which is installed on the polyvinyl chloride tube circuit. To monitor the pressure, pressure monitoring gauges can be used in the inlet and outlet pipes of the test circuit. The temperature of the blood in the test circuit can be controlled by immersing part of the circuit in a constant temperature bath to perform the hemolysis test. However, the temperature in the test circuit is localized, and with a total length of two meters, it is difficult to maintain a constant temperature of 37°C ± 1°C throughout the test circuit through local heating. In the laboratory, due to the excessive length of the pipe, the circuit is relatively messy and folded due to the excessive number of devices connected to the circuit. The pipes in the circuit often need to be moved, which causes collisions between the blood and auxiliary equipment, increasing the risk of hemolysis and thus affecting the test results. Therefore, we propose a heating device to assist mechanical force-mediated hemolysis testing. Utility Model Content
