The invention relates to an application of zinc-based montmorillonite and calcium-based montmorillonite sterile styptic powder in preparation of medicines for healing skin wounds. The zinc-based montmorillonite and calcium-based montmorillonite sterile styptic powder is prepared from the following raw materials in parts by mass: 5-10 parts of zinc-based montmorillonite and 8-12 parts of calcium-based montmorillonite. According to the invention, zinc-based montmorillonite and calcium-based montmorillonite are used as effective ingredients of the medicament provided by the invention, and the effective ingredients are combined with pharmaceutical auxiliary materials to be prepared into the medicament through the processes of high-temperature dry heat sterilization, mixing, sterile sub-packaging and the like. Through skin external administration, the medicament can be used for quickly coagulating blood and arresting bleeding as well as preventing wound infection, has anti-bacterial and anti-inflammatory effects, and has converging and healing effects on the injured skin.

The invention relates to a method for automatically constructing a stable electrocatalytic bacterial biofilm. The method comprises the following steps: firstly assembling a microbe electrochemical reactor, and connecting circuits, wherein the first circuit is as follows: a fixed resistor is connected between an anode and a cathode in series, and the second circuit is as follows: an adjustable direct-current power supply, an ampere meter and a work contact of a circulating time relay are connected between the cathode and the anode; then injecting a bacteria growth medium solution into an anode chamber, inoculating a bacteria source, prestarting a microbe anode by switching on the first circuit, then controlling pulse current between the anode and the cathode to be gradually increased at preset velocity according to the potential change of the anode by switching on the adjustable direct-current power supply of the second circuit, wherein the pulse current is immediately lowered by 40%-60% when the potential of the anode is increased to a limit value and enters a new round of growth stimulation, and the electrocatalytic bacterial biofilm is completely constructed till the pulse current value reaches a preset current limit value and is stable at the preset current limit value for more than 10 hours. The electrocatalytic bacterial biofilm disclosed by the invention can be stably operated with the relatively high working current.
