Embodiment 1

[0028] (1) After the boiled egg yolk is pulverized and dried, it is added to water and mixed evenly. According to the mass ratio of egg yolk and protease is 1:0.05, protease is added, hydrolyzed at 4°C for 30 minutes, centrifuged, extracted with ethanol, and the ethanol is removed to obtain Purified egg butter.

[0029] (2) According to the mass ratio of 8:12:16, add polyethylene glycol diacrylate, polyethylene glycol, and polyvinylpyrrolidinol into water, stir and dissolve thoroughly, raise the temperature to 90°C and continue stirring for 30 minutes, then lower the temperature to After reaching room temperature, 0.5% initiator Irgacure 2959 was added to the total volume, cured at 10W power for 10s, and then cured at 30W power for 30s to obtain an acrylic acid hydrogel with a crosslinking degree of 25%.

[0030] (3) Freeze the acrylic hydrogel at -20°C, and then vacuum-dry it for 0.5 d to obtain a dry acrylic hydrogel.

[0031] (4) Take out the dried acrylic acid hydrogel, a...

Embodiment 2

[0034] (1) After the boiled egg yolk is crushed and dried, it is added into water and mixed evenly. According to the mass ratio of egg yolk and protease is 1:0.08, protease is added, hydrolyzed at 8°C for 90 minutes, centrifuged, extracted with ethanol, and the ethanol is removed to obtain Purified egg butter.

[0035] (2) According to the mass ratio of 10:20:18, add polyethylene glycol diacrylate, polyethylene glycol and polyvinyl pyrrolidin into water, stir and dissolve thoroughly, raise the temperature to 100°C and continue stirring for 30 minutes, then lower the temperature After reaching room temperature, 1% initiator Irgacure 2959 was added to the total volume, cured at 15W power for 15s, and then cured at 50W power for 45s to obtain an acrylic acid hydrogel with a crosslinking degree of 28%.

[0036] (3) Freeze the acrylic hydrogel at -30°C, and then dry it in vacuum for 2 days to obtain a dry acrylic hydrogel.

[0037](4) Take out the dried acrylic acid hydrogel, add ...

Embodiment 3

[0040] (1) After the boiled egg yolk is crushed and dried, it is added into water and mixed evenly. According to the mass ratio of egg yolk and protease is 1:0.05, protease is added, hydrolyzed at 8°C for 30 minutes, centrifuged, extracted with ethanol, and the ethanol is removed to obtain Purified egg butter.

[0041] (2) According to the mass ratio of 10:12:18, add polyethylene glycol diacrylate, polyethylene glycol and polyvinylpyrrolidinol into water, stir and dissolve thoroughly, raise the temperature to 90°C and continue stirring for 30 minutes, then lower the temperature After reaching room temperature, 1% initiator Irgacure 2959 was added to the total volume, cured under 10W power for 15s, and then cured under 30W power for 45s to obtain an acrylic acid hydrogel with a crosslinking degree of 25%.

[0042] (3) Freeze the acrylic hydrogel at -30°C, and then vacuum-dry it for 0.5 d to obtain a dry acrylic hydrogel.

Abstract

The invention discloses a preparation method of an electromagnetic shielding medical gel material containing egg yolk oil / lipidosome. The preparation method comprises the following steps: pulverizingand drying boiled egg yolk, adding into water, mixing evenly, adding protease to hydrolyze, centrifuging, extracting with ethyl alcohol, and removing the ethyl alcohol to obtain the purified egg yolkoil; adding polyethylene glycol diacrylate, polyethylene glycol and polyvinylpyrrolidone into water, fully stirring, dissolving, heating, continuing to stir, cooling to the room temperature, adding aninitiator, and curing with ultraviolet to obtain an acrylic acid hydrogel; freezing and drying in vacuum the acrylic acid hydrogel, taking out the acrylic acid hydrogel, adding the egg yolk oil and ametal salt solution, slowly stirring until the acrylic acid hydrogel recovers to the room temperature, and fully adsorbing to obtain the egg yolk oil containing acrylic acid gel loaded with the metalsalt; curing the egg yolk oil containing acrylic acid gel, slowly adding into the lipidosome, stirring evenly, and swelling overnight to obtain the electromagnetic shielding medical gel material containing the egg yolk oil / lipidosome.

Description

technical field [0001] The invention belongs to the technical field of medical materials, and in particular relates to a preparation method of an electromagnetic shielding medical gel material containing egg oil / liposome. Background technique [0002] With the development of science and technology, the use of radiation is becoming more and more extensive, especially in medicine. Radiation plays a pivotal role in medical treatment and diagnosis, and has good therapeutic effects in the treatment of breast cancer, uterine cancer, esophageal cancer, and lung cancer. However, while the application of ionizing radiation has brought huge benefits to people, it also has great side effects, such as dizziness, fatigue, nausea, vomiting and even carcinogenic symptoms. Therefore, to minimize the harm to people is to develop radiation-proof materials important purpose. [0003] Gel is a viscoelastic dispersion system in a semi-solid state. In its system, polymer molecules or colloidal p...
