Embodiment Construction
[0026] refer to figure 2 , figure 2 Schematic diagram of the nuclear pore filter membrane provided by the embodiment of the present invention.
[0027] like figure 2 As shown, the nuclear pore filter membrane provided in this embodiment includes a filter membrane substrate 1 and a plurality of filter holes 2, the thickness of the filter membrane substrate 1 is 7 μm to 10 μm, and a plurality of filter pores 2 are distributed on the filter membrane substrate 1 and the distribution density is 5×10 5 ~1×10 6 pieces / square centimeter.
[0028] The filter hole 2 is a circular through hole, the angle between the axis of the circular through hole and the filter membrane substrate 1 is 70°~90°, and the diameter of the filter hole 2 is 4.10 μm~4.55 μm. Specifically, the filter hole 2 may be a straight circular hole perpendicular to the filter membrane substrate 1, or an oblique circular hole at an angle of 70°-90° with the filter membrane substrate 1. The material of the filter...

Abstract
The invention provides a nuclear pore filter membrane and a manufacturing method thereof. The nuclear pore filter membrane comprises a filter membrane base body and a plurality of filtration pores. The thickness of the filter membrane base body is 7 micrometers to 10 micrometers, the filtration pores are distributed on the filter membrane base body, and the distribution density of the filtration pores is 5*105-1*106 per square centimeter; the filtration pores are round through holes, included angles between the axes of the round through holes and the filter membrane base body are 70 degrees to 90 degrees, and the diameter of the filtration pores is 4.10 micrometers to 4.55 micrometers. In the nuclear pore filter membrane, due to the fact that the filtration pores are the round through holes, in practical application, particles with the diameter smaller than that of the filtration pores can pass through the filtration pores easily, the filtering accuracy and the filtering rate are met, and meanwhile flow attenuation cannot be caused.
Description
technical field [0001] The invention relates to the filtration technology of an infusion set, in particular to a nuclear pore filter membrane and a manufacturing method thereof. Background technique [0002] Infusion therapy has become one of the indispensable conventional means and methods in modern clinical treatment, and has an extremely important position in modern clinical treatment. Existing infusion sets are equipped with filters to filter harmful particles in the liquid medicine, so as to avoid cross-infection during the infusion process and reduce the harm of insoluble particles in the liquid medicine to the human body. [0003] There are many kinds of filter materials used on the filter, among which the nuclear pore filter membrane is a filter membrane capable of precise filtration. figure 1 It is a schematic diagram of an existing nuclear pore filter; such as figure 1 As shown, the existing manufacturing method of nuclear pore filter membrane is: utilize high-en...
