Embodiment 1
[0035] Embodiment 1 Electric double layer treatment increases blood collection tube hydrophilicity
[0036] 1. Use a plasma surface treatment device to perform plasma treatment (300W, 13.56MHz, 3min) on the blood collection tube to remove the contamination impurities on the surface and make the surface negatively charged. Then soak the blood collection tube in the PAH polycation aqueous solution with a concentration of 0.01mol / L for 15 minutes, take it out and wash it with distilled water gradient for 3 times, each time for 2 minutes, and then soak the blood collection tube in the Ludox SM-30 aqueous solution with a concentration of 0.03% After 15 minutes, take it out and wash it with gradient distilled water for 3 times, 2 minutes each time. The above steps are one operation cycle, and one operation cycle will obtain a composite coating consisting of one layer of PAH cation layer and one layer of Ludox SM-30 anion layer on the glass surface, which is called an electric double...

[0040] Example 2 Concentrated sulfuric acid treatment increases the hydrophilicity of blood collection tubes
[0041] 1. The steps for treating glass tubes with concentrated sulfuric acid solution are as follows:
[0042] 1) Clean the glass tube ultrasonically with 75% ethanol for 10 minutes, then ultrasonically clean it 6 times with ultrapure water, and dry it with nitrogen;
[0043] 2) wash with ethanol and ultrapure water respectively, soak in concentrated sulfuric acid (95%-98%) for 12 hours, then ultrasonically clean with ultrapure water for 6 times, rinse with high pressure, and blow dry with nitrogen;
[0044] 3) Sterilized by gamma ray irradiation and packaged.
[0045] like image 3 As shown, after concentrated sulfuric acid treatment, the water contact angle on the glass surface changed. The contact angle before modification was 32°, but after concentrated sulfuric acid treatment, the contact angle was 11.2°, and the glass surface was hydrophilic.

Embodiment 3
[0048] Embodiment 3 Piranha solution processing increases the hydrophilicity of blood collection tubes
[0049] 1. The steps of applying piranha solution to treat blood collection tubes are as follows:
[0050] 1) Clean the blood collection tube with 75% ethanol ultrasonically for 10 minutes, then ultrasonically clean it with ultrapure water for 6 times, and dry it with nitrogen gas;
[0051] 2) Prepare piranha solution with 98% concentrated sulfuric acid and 30% hydrogen peroxide solution according to the volume ratio of 7:1, soak the blood collection tube in the piranha solution for 12 hours, then ultrasonically clean it with ultrapure water for 6 times, and Rinse and blow dry with nitrogen;
[0052] 3) Vacuum the centrifugal blood collection tube, and put on the suitable butyl rubber stopper cap under the vacuum state;
[0053] 4) Sterilized by gamma ray irradiation and packaged.
[0054] To detect its water contact angle, such as Figure 5 As shown, after the piranha s...
