Abstract

The invention discloses a monocrystalline silicon precision infusion filter membrane, a preparation method thereof, a filter and an infusion device. The monocrystalline silicon precision infusion filter membrane comprises a body. The body is provided with a monocrystalline silicon filter membrane and a monocrystalline silicon grid support body arranged on the side of the monocrystalline silicon filter membrane and integrally connected to the monocrystalline silicon filter membrane. The monocrystalline silicon filter membrane is provided with a plurality of penetrating filtering holes with thediameter of 0.2-5 microns and the depth of 2-50 microns. The filter membrane has good bonding strength and sealing performance, ensures the sound condition under the stress state, solves the problemsof low thickness and brittleness, has the advantages of short filtering path, high structural strength, good sealing performance, low filtration pressure difference, low filter membrane swelling and less drug adsorption, and can better meet the ultrafiltration requirements of different types of drug infusion.

Description

technical field [0001] The invention relates to a precision infusion filter membrane made of monocrystalline silicon, a preparation method thereof, a filter and an infusion set. Background technique [0002] At present, intravenous infusion is one of the most common methods of drug delivery. The active ingredients in the drug solution are transported into the human blood circulation system to treat the diseased area, which has become a common drug treatment method. The common problem faced by this kind of drug delivery is that due to the limitations of the current drug production technology and environmental conditions such as transportation and storage, the drug solution often still contains microparticles of different diameters, and the infusion process enters the blood system together with the effective drug components, and It will have varying degrees of impact on human health, and may cause serious harm to human tissues or organs, and in severe cases may endanger human ...
