Dialysis device special for regenerated silk fibroin laboratory and use method of dialysis device

Abstract

The invention provides a dialysis device special for a regenerated silk fibroin laboratory and a use method of the dialysis device. The dialysis device special for the regenerated silk fibroin laboratory comprises a box body, wherein at least one fixing stick for fixing a dialysis bag for filling a regenerated silk fibroin solution is fixed at the top end of the box body; the box body is provided with a water supply system, a water drainage system and a water discharging system; the water supply system and the water drainage system share a connection opening and a water pipe; the connection opening is formed in the bottom surface of the box body and is connected with the water pipe; a valve is arranged on the water pipe; the water discharging system comprises a water outlet formed in the side wall of the box body; and the water outlet is connected with a water discharging pipe. The dialysis device is simple in structure and convenient to use; and a more flexible scheme is supplied to different scales of dialysis of the regenerated silk fibroin solution, so that the number and the lengths of the dialysis bags are optimized, and waste is avoided. The dialysis device realizes continuous, dynamic and full dialysis of the regenerated silk fibroin solution, greatly saves labor and time and reduces the risk of dialysis pollution.

Description

technical field [0001] The invention relates to a laboratory-specific dialysis device for regenerated silk fibroin and a method for using the same, belonging to the technical field of biomedical material equipment and preparation. Background technique [0002] China is a big silk producing country, and the annual output of raw silk accounts for about 70-80% of the world's total output. Silk surgical sutures have been used clinically for hundreds of years, and have produced huge economic benefits and good social benefits. With the development of silk molecular biology and the advancement of advanced technology, silk fibroin has been increasingly researched and applied in the field of biomedical materials. In addition to the above-mentioned surgical sutures, there are also artificial blood vessels, artificial skin, wound dressings, tissue engineering scaffolds, and drug sustained-release carriers. The application forms are also increasingly abundant, including woven yarns, w...

Problems solved by technology

Obviously, this dialysis method has at least the following disadvantages: (1) the materials of daily water basins and buckets do not meet the requirements for the preparation of medical materials, which may affect the biocompatibility of materials; (2) the container capacity is not carefully calculated, often resulting in Fluctuation of liquor ratio, dialysis effect is unstable; (3) the effect of static dialysis is insufficient; (4) open container easily causes bacterial contamination and breeding; (5) manpower and time waste are caused by manual water change; (6) ) The regenerated silk fibroin solution may not be completely immersed in water, and the dialysis is insufficient; (7) The capacity of the dialysis bag cannot be well matched with the water container, which may cause waste of the dialysis bag; (8) Excessive cutting of the dialysis bag, It will cause waste of dialysis bags; (9) there is no drainage system, which is time-consuming and laborious; (10) the volume of the beaker is limited and the dialysis is not sufficient, which limits the amount of regenerated silk fibroin prepared each time

However, after reading and comparing, it is not difficult to find that the devices described in the above three patents are significantly different from the present invention in terms of structure, function, and field
