Problems solved by technology

[0006] This is a national standard, which only requires the light transmittance of light-proof infusion sets in the wavelength range of 290nm~450nm. However, due to the complexity of clinical drugs and the diversity of modern light pollution, the light-proof infusion parts of existing light-proof The range is not enough to meet the needs

Embodiment 1

[0065] In the test results of Example 1, the light transmittances of 220nm~290nm, 290~450nm, 450nm~520nm are respectively 0~0.2%, 0~0.2%, 0~3.9%, which all meet the national standards and are far Far below the national standard. However, its light transmittance is only 49% in the wavelength range of 0%, and its effect can only be maintained between 46%-50% in a large number of experiments.

Embodiment 2

[0066] It can be seen from the test results of Example 2 that in the wavelength ranges of 290nm~450nm, 220nm~290nm, and 450~520nm, the light transmittance is 0%, 0~0.2%, and 0~3.9% respectively, which are in line with national regulations. Standards. Among them, 290nm~450nm is the nationally regulated test wavelength range, 220nm~290nm, 450~515nm beyond the conventional wavelength range can also reach the national standard. In the nationally regulated test wavelength range of 290nm~450nm, the light transmittance standard is drip bucket≤35%, pipeline≤15%, and the performance of this section in Example 2 is 0~0.2%, which is far lower than the national standard. It can be seen that its light-shielding effect has also been significantly improved. In the new wavelength range of 220nm~290nm, 450~520nm, the detection results are 0~0.2%, 0~3.9%, it can be seen that it also has good performance. The pellets and films made of this group of raw materials have 66% of the wavelength range...

Embodiment 3

[0067] In the test results of the third embodiment, the light transmittances of 220 nm to 290 nm, 290 to 450 nm, and 450 nm to 520 nm are 0%, 0 to 0.2%, and 0 to 3.9%, respectively, which all meet the national standards. However, the wavelength range with 0% light transmittance is only 58%. In a large number of experiments, the wavelength range with 0% light transmittance can only be maintained between 50% and 60%.

[0068] In summary, according to the ratio of the examples of the present invention, the second embodiment has the most significant and stable effect, which can be a preferred solution of the present invention.

[0069] The invention has a wide band and high light-shielding performance, and the effective light-shielding range has jumped from the 290nm-450nm wavelength range required by the original national standard to the 220nm-520nm wavelength range, and even a wider range. The light-shielding range is significantly improved; High light-shielding effect, the overall l...

Abstract

The invention belongs to the technical field of light-avoiding medical material, and especially relates to a medical-grade wide-waveband high-light avoiding performance polyvinyl chloride granula. The medical-grade wide-waveband high-light avoiding performance polyvinyl chloride granula comprises following main ingredients: polyvinyl chloride resin, bis(2-ethylhexyl)phthalate, epoxidized soybean oil, zine stearate, calcium stearate, stearic acid, oxidized polyethylene, 2-hydroxy-4-(octyloxy)benzophenone, stearoyl benzoyl methane, azo condensation pigment yellow, and diketo-pyrrolo-pyrrole. The medical-grade wide-waveband high-light avoiding performance polyvinyl chloride granula possesses a wide light-avoiding waveband which ranges from 220 to 520nm and is wider than a waveband required by national standards ranging from 290 to 450nm; and possesses high light-avoiding performance; light transmittance ranges from 0 to 3.9% in the waveband ranging from 220 to 520nm; light-avoiding performance of the original waveband is increased from no more than 15%, which is required by existing national standards, to 0.2%; entire light transmittance of the new waveband is improved to be 4% or less; and light-avoiding performance is improved. The medical-grade wide-waveband high-light avoiding performance polyvinyl chloride granula possesses high light-avoiding performance in the wide waveband, is capable of increasing performance of light-avoiding parts effectively, and increasing photosensitiveness medicine administration safety of medical infusion equipment.

Description

technical field [0001] The invention relates to the technical field of light-shielding medical materials, in particular to a medical-grade wide-band high light-shielding polyvinyl chloride pellet. Background technique [0002] In clinical practice, some drugs need to be infused under dark conditions, such as sodium nitroprusside, nitroglycerin, vitamin B 2 etc., general infusion set just can't meet this infusion requirement, needs to use specific light-proof infusion set. All parts of the light-proof infusion set in contact with the liquid medicine should have light-proof properties. For the light-shielding performance, the most direct method is to evaluate the application of clinically used drugs. [0003] The existing national standard for measuring light transmittance of light-proof infusion set is: the light transmittance of the infusion set within the wavelength range of 290nm~450nm must meet the requirements in Table 1. [0004] Table 1 Limits of light transmittanc...
