[0002] In the field of medical technology, medical devices are needed in the process of testing blood of patients. During the use of blood coagulation needles and ten-item test cards for Qi and blood, due to the different viscosity and liquid components of the test solution, blood, etc., there will be Blood remains on the blood coagulation needle and the ten test cards of Qi and blood, resulting in inaccurate liquid volume and inaccurate testing.
[0003] At present, the common practice in the market is that these medical devices are coated with a hydrophobic coating layer before use to alleviate the problem of blood residue. This method of coating a hydrophobic coating layer has the defects of high efficiency, low cost and uneven coating.

Abstract
The invention relates to a transparent hydrophobic ABS plastic for medical apparatus and instruments, and belongs to the technical field of material preparation. According to the transparent hydrophobic ABS plastic for the medical apparatus and instruments, ABS resin, a solid dispersing agent, a first lubricating agent and a second lubricating agent are adopted as raw materials to prepare the transparent hydrophobic ABS plastic. According to the transparent hydrophobic ABS plastic, the transparent ABS resin is adopted as a main raw material to improve the gloss of the material; meanwhile, thepenetration requirement of ultraviolet rays can also be met. Normal-temperature and high-temperature tests are carried out on a medical instrument prepared from the transparent hydrophobic ABS plasticand ten common medical solvents, and after the tests, the product has no adverse reaction, no precipitation or no crosslinking reaction. In a word, the medical instrument prepared from the transparent hydrophobic ABS plastic for the medical apparatus and instruments has good hydrophobic performance; the medical instrument can form a long-term self-lubricating surface to achieve a hydrophobic effect, the finally prepared medical instrument product is in a semitransparent state, ultraviolet light can penetrate through the medical instrument product, the stability of the medical instrument product system is excellently reflected in different test solvents, and the medical instrument product system is wide in range, safe, reliable and suitable for application and popularization.
