Method for preparing nano-silver thread

Abstract

The invention discloses a method for preparing a nano-silver thread, which comprises the operation steps of: preparing 1 mmol of silver nitrate solution and 2 mmols of sodium borohydride solution respectively, then preparing the two solutions into a nano-silver colloid solution, then preparing the nano-silver colloid solution into a nano-silver gelatin solution, performing heating and concentration on the nano-silver gelatin solution, then performing water bath heat preservation on the concentrated nano-silver gelatin solution to ensure that the mixed gelatin solution is in a melted state, then soaking a suture which can be absorbed by human bodies into the nano-silver gelatin solution for a period of time, then uniformly drawing out of the suture at a preset rate, and naturally drying the suture; and thus ensuring that the nano-silver gelatin mixed solution with corresponding viscosity forms a layer of thin glue film on the suture to obtain the nano-silver thread. The method has simple and easy operation steps; used instruments are commonly used experimental vessels; and the prepared nano-silver wire has the surface silver content of between 15 and 300 ng/cm, is used as a novel thread body for catgut embedding therapy, can play roles in infection resistance, sterilization, inflammation diminishing and the promotion of wound healing of surface element-silver, and can increase the therapeutic effect, repair and stimulate the regeneration of organisms when embedded into tissues for a long time.

Description

technical field [0001] The invention relates to a method for preparing nano silver wires, more precisely, relates to a method for manufacturing nano silver wires for non-invasive catgut embedding treatment, and belongs to the technical field of medical appliances or medical matching materials. Background technique [0002] At present, thread embedding therapy is often used in clinical medicine: a method of embedding thread bodies in acupoints of the human body for physical therapy. It uses the continuous stimulation of the embedded thread bodies to acupoints to replace traditional acupuncture treatment. Decades of medical practice has proved that catgut embedding therapy is a medical method with good curative effect. Because the traditional catgut embedding therapy has a certain degree of trauma, it has not been paid enough attention and developed, and it is rarely used clinically now. However, in recent years, due to the emergence of new needles, the current catgut embeddi...
