Biomaterial gas reinforcing device

Abstract

The invention discloses a biological material gas reinforcing device which comprises a nitrogen generating device, a gas generating device and a gas reinforcing box body, the nitrogen generating device is communicated with the gas generating device through a pipeline, and the gas generating device is communicated with the gas reinforcing box body through a pipeline; the gas generating device is used for containing volatile strengthening liquid, and a biological material to be strengthened is placed in the gas strengthening box body. According to the biological material gas reinforcing device provided by the invention, a pneumatic transmission principle is adopted, nitrogen is filled into the gas generating device from the positive pressure end of the nitrogen generating device, and volatile gases, such as formaldehyde, glyoxal and glutaraldehyde, in the gas generating device enter the gas reinforcing box body at normal pressure along with the nitrogen; nitrogen flow is adjusted through a pressure reducing valve and a flow controller at the positive pressure end of the nitrogen generation device so as to control the volume / weight of volatile gas flowing into the gas strengthening box body, and the strengthening effect of the biological material is controlled by controlling the flow speed and time of nitrogen.

Description

technical field [0001] The invention relates to the technical field of biomaterial chemical gas crosslinking, and more specifically relates to a biomaterial gas strengthening device. Background technique [0002] Tissue engineering and regenerative medicine is a new discipline with rapid development in the 21st century. It uses good biomaterials, different types of cells and tissue growth factors to repair the damaged parts of the body's organs or tissues. This high-tech concept , technology and methods can be applied to various fields of medicine, which is a major development of medical science in the 21st century; however, due to the weak biomaterial itself, the degradation resistance of biomaterials is relatively fast, and the damaged tissue cells have not been completely repaired; through physical Or chemical cross-linking technology can improve the strength characteristics of biomaterials, improve their degradation performance, prolong their residence time in the body, ...

Problems solved by technology

[0003] However, the physical cross-linking effect is weak, and the chemical cross-linking technology is more needed. However, the realization of chemical cross-linking is mostly strengthened by liquid immersion. There are chemical residues after soaking in liquid of biological materials, and the existing form of liquid is easy to change some of the samples. Features: The gas chemical cross-linking method is safer, more reliable, more convenient and quicker. At present, there is no strengthening device with controllable gas concentration and uniform gas dispersion in China.
