Description
Technical Field
The invention relates to the field of degradable biological material experiments, in particular to a degradable biological material dynamic degradation device and a monitoring system.
Background
The degradable biological material such as certain metal and macromolecule implantation products can have different influences on the degradation time and the surrounding environment of the products due to different implantation positions, different stress, different degradation mechanisms and the like in the degradation process of human bodies.
The medical biodegradable material is mainly used for human bodies, is directly related to life and health of the human bodies, and has no toxic or side effect. The method requires high material purity, very clean production environment, less auxiliary agent residue and impurity content of ppm level, and ensures no disease and no toxic transmission condition. While the compounds themselves and monomeric impurities, degradation or abrasion products do not adversely affect the body. The physical, chemical and mechanical properties are required to meet the requirements of the design and function required by the medical use. Such as hardness, elasticity, mechanical strength, fatigue strength, creep, abrasion, water absorption, dissolution, enzyme resistance, in vivo aging, and the like. For example, heart valves are preferably used for 25 ten thousand hours, and particularly good fatigue strength is required. In addition, it is also required to facilitate sterilization, to withstand wet heat sterilization (120-140 ℃), dry heat sterilization (160-190 ℃), radiation sterilization or chemical treatment sterilization without degrading the properties of the material. Medical polymer materials with different properties can be sterilized in a proper mode according to specific conditions. Can have certain in vivo adaptability: including compatibility with other materials in medical supplies, biocompatibility, blood compatibility and tissue compatibility of materials with the human body. After the material is implanted into a human body, the material is required to have no influence on body fluid for a long time. The artificial kidney filtration membrane and the artificial lung gas exchange membrane each having a separation dialysis function, and the artificial blood gas-absorbing and desorbing substances and the like are required to have specific separation permeation functions.
After the medical biodegradable material is implanted into a human body, the PH value of the human body part has certain hydrogen evolution corrosion to the medical polymer material, namely the PH value in the human body has great influence on the hydrogen evolution corrosion speed, and the corrosion speed is rapidly increased along with the decrease of the PH value, so that the hydrogen evolution reaction is promoted. The PH decreased and Eec shifted forward, increasing the tendency to corrosion. Thus not only affecting the use of medical biodegradable materials, but also easily causing harm to human bodies.
At present, before the medical biodegradable material is used, the medical biodegradable material which is easy to generate hydrogen evolution corrosion needs to be tested, and the use performance of the medical biodegradable material is analyzed. The current medical biodegradable material test is carried out only manually by adjusting the reagent in a test tube. The test time, the usage amount of the metering reagent, the test process data and the like are manually metered, so that not only the test precision is affected, but also the test process data and the result data are manually recorded.
In addition, the current test process is carried out singly, namely the operation process of each experiment is carried out independently, each experiment process can not be recorded manually if mutual comparison and reference are needed, one comparison is carried out after the test is completed, and the data information of the experiment process can not be compared in the test process. Some tests need to be repeated for a plurality of times under different use environments or different external environments, and in this case, the comparison of the test process data can only be performed after the test is completed, so that the real-time comparison and analysis of the test process data cannot be performed.
