Abstract
The invention discloses a continuous nanofiber medical yarn equipment control system and method. The system includes a collection device, a host computer, a controller, a high-voltage generator, a supply fan, an exhaust fan, a thermal spray gun, a peristaltic pump module and a motor module. The acquisition device is connected to the host computer, and the controller is respectively connected to the host computer, high voltage generator, air supply fan, exhaust fan, thermal spray gun, peristaltic pump module and motor module. Applying the present invention to the production of nanofiber medical surgical threads in domestic hospitals and the manufacture of related equipment will change the current situation that domestic high-performance surgical threads are all dependent on imports, gradually eliminate low-end non-degradable surgical threads, and reduce the pain of surgical patients. Aiming at the problems of low efficiency and complex process in the current medical spinning technology, by modeling the trajectory of the ejected nanofibers, the entire collection process of the nanofibers can be precisely controlled to achieve high efficiency and uniformity of medical nanofiber collection.
Description
technical field [0001] The present invention relates to the field of medical yarn equipment control, and more particularly, to a continuous nanofiber medical yarn equipment control system and method. Background technique [0002] At present, the collection methods of continuous electrospun nanofibers at home and abroad are very single, that is, they are all collected in the form of non-woven webs. However, due to the unstable "whip" state of the jet during the spinning process, the fibers on the receiving device The arrangement of nanofibers is often chaotic, and the final nanofibers are similar to a net. The utilization of nanofibers requires a second process, which is inefficient. The key to the above problems is that it is difficult to control the trajectory of electrospun nanofibers, and no device is used to optimize the trajectory of the prepared nanofibers, which severely limits the development prospects of continuous electrospun nanofibers. Contents of the invention...
