It will be clear to those skilled in the art that strong base can kill bacteria and viruses carried by the raw material of biological tissue, that biological enzymes can remove antigenicity of the raw material of biological tissue, that washing solutions can wash biological tissue or treated products, that combination of biological enzymes and washing solutions can decellularize biological tissue, and so on. During processing, the biological tissue raw material is processed into a biological derivative material by performing cross treatment on the biological tissue raw material through strong alkali, biological enzyme, washing liquid and pure water. Since the process of preparing the biological tissue raw material into the biologically derived material is well known in the art, the detailed description of the process for preparing the biologically derived material is omitted here.
When the treatment system provided by the invention is used for processing and treating biological tissue raw materials, the biological tissue is in the reaction kettle in the whole processing and treating process and is isolated from the outside, so that pollution can be effectively prevented. In different treatment steps, the invention adds different treatment liquids by controlling the liquid inlet of the first reaction kettle so as to disinfect, clean, decellularize and remove antigenicity of biological tissues. After the treatment is finished, the invention can discharge the waste treatment liquid by controlling the liquid discharge of the first reaction kettle, thus realizing the replacement of the treatment liquid, and having simple and convenient operation, time and labor saving and low pollution risk.
The biological tissue is placed in the filter screen container of the net cage, the full contact between the biological tissue and the treatment liquid is not influenced, and the treatment product can be effectively prevented from being discharged when the treatment waste liquid is discharged, so that the treatment product is continuously left in the filter screen container for the next treatment. Meanwhile, the filtering holes of the filter screen containers can be designed into various specifications, and a plurality of filter screen containers can be placed in the net cage at the same time, so that the system can simultaneously treat a plurality of same biological tissue raw materials with the same or different specifications, the treatment is convenient, the treatment efficiency is obviously improved, and the treatment cost is also obviously reduced.
The working principle of the biological tissue treatment system is as follows: before treatment, the biological tissue is placed in a filter screen container, then the filter screen container is placed in a net cage, then the net cage is placed in a first reaction kettle, and the first reaction kettle is sealed. Washing liquid is added into the second reaction kettle through a feed port B3, strong base is added into the third reaction kettle through a feed port C3, and biological enzyme is added into the fourth reaction kettle through a feed port D3. In the treatment process, pure water is added into the first reaction kettle through the A2 feed inlet, washing liquid, strong base and biological enzyme are added into the first reaction kettle through the A3 feed inlet, and waste liquid is discharged from the first reaction kettle through the A discharge outlet. Meanwhile, the washing liquid is discharged from the second reaction kettle through the discharge port B and is conveyed to the feed port A3, the strong base is discharged from the third reaction kettle through the discharge port C and is conveyed to the feed port A3, and the strong base is discharged from the fourth reaction kettle through the discharge port D and is conveyed to the feed port A3. It can be seen that this system through the switch of controlling each feed inlet and bin outlet, can nimble control in the first reation kettle different treatment fluid (be alkali, washing liquid, biological enzyme and pure water) add and the discharge of handling the waste liquid to realize carrying out the processing of multistep to biological tissue, make it form biological derived material, process flow is simple, convenient operation, a large amount of biological tissue of disposable, the treatment effeciency is high. Moreover, the biological tissues are all in the first sealed reaction kettle in the whole treatment process and are isolated from the outside, so that the pollution is effectively prevented. In addition, in the processing procedure, the height of the two sides of the swing platform is changed by controlling the extension and contraction of the driving shafts of the two groups of cylinders, so that the first reaction kettle swings left and right, the raw materials of the biological tissues in the kettle are fully contacted with the treatment liquid, and the treatment effect and the treatment efficiency are further improved. After the treatment was completed and the product was taken out, pure water and pure steam were added to the first reaction vessel through the feed port A1 and the feed port A2, respectively, to clean and sterilize them. In addition, pure water and pure steam can be added into the second reaction kettle through the feed port B1 and the feed port B2, pure water and pure steam can be added into the third reaction kettle through the feed port C1 and the feed port C2, and pure water and pure steam can be added into the fourth reaction kettle through the feed port D1 and the feed port D2, so that the second reaction kettle can be cleaned and sterilized.
Taking the process flow chart of the process for producing the biological bone repair material as shown in fig. 5 as an example, the biological tissue raw material can be processed in the processing system of this embodiment from the "decellularization" step to the "lyophilization" step. Therefore, the processing system of the invention replaces the existing manual operation, not only can simplify the preparation process of the biological derivative material, reduce the pollution risk, improve the preparation safety and the preparation efficiency and reduce the preparation cost, but also can ensure the consistency of the system to the biological tissue by setting the same working parameters, thereby ensuring the product quality.
Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the protection scope of the present invention, and although the present invention is described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions can be made on the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
