Abstract
The invention discloses a method for synthesizing a negative-pressure closed drainage material. The method includes the following steps that firstly, purified water is added into a three-mouth flask of 2000 ml, and then 150 g of polyethylene glycol and derivatives of the polyethylene glycol are added to be stirred and dispersed evenly; secondly, the temperature is raised slowly to a specific temperature, the temperature is kept, stirring is conducted continuously till the polyethylene glycol and the derivatives of the polyethylene glycol are fully dissolved, and the temperature is lowered to room temperature; thirdly, a mixture of aldehyde condensing agents, ester emulsifying agents, aldehyde cross-linking agents and alcohol dispersing agents is added into the three-mouth flask once and continuously stirred till the mixture is uniform; fourthly, foaming agents and catalysts are added, foam mixed liquid obtained after foaming is injected into the die and solidified. The sizes of pores of the negative-pressure closed drainage material can be well controlled, the sizes of the pores are uniform, uniformity of negative pressure and absorption stability of body fluids and necrotic tissue in the later use process are facilitated, and usability and durability of the negative-pressure closed drainage material are greatly improved.
