Abstract

A powder spraying method includes: an accommodating cavity filled with powder is communicated with a pressure gas source, gas is allowed to enter the accommodating cavity, the gas pushes the powder to be sprayed out through a spraying catheter communicated with the accommodating cavity, wherein the pressure intensity at the outlet of the spraying catheter is 0.02-50KPa. The method has the advantages that the method is applicable to wound bleeding caused by injuries or surgeries, and visualized hemostasis of wounds of organs, tissues or parts which are hard to reach can be achieved by the method matching with a hemostasis device and hemostasis material.

Description

technical field [0001] The invention relates to a method of powder spraying, in particular to a powder spraying driven by an airflow to realize hemostasis on wounds, and a device suitable for the method. Background technique [0002] At present, for traumatic bleeding caused by trauma or surgery, no matter what kind of hemostasis technique is used, it is inseparable from the conventional means of "compression hemostasis". Common ones are: Band-aids for external trauma, and hemostatic sponges, hemostatic microspheres, hemostatic medical membranes and hemostatic gauze made by non-woven technology used in various operations. Although these hemostasis techniques have effectively improved the hemostatic efficiency, they must be compressed for a period of time before the external force is removed, and it must be observed whether there are still bleeding points at the wound. If there is still bleeding, continue to use hemostatic agent and apply pressure again until hemostasis is a...
