Traditional hemostatic material (such as cotton yarn, bandage, tourniquet) is existing for irregular shape, deep, narrow, arteriorrhexis etc.
The haemostatic effect of the common wound in field is very unsatisfactory.Inorganic mineral such as zeolite hemostatic material is difficult to use under windy environment, and
It may cause third-degree burn, or even residual vascular and lung lead to thrombus.ɑ-cyanoacrylate hemostatic material degradation process
In then inevitably release the noxious materials such as a small amount of cyanogen and formaldehyde, cause tissue inflammation.With the development of science and technology, people by
Gradually center of gravity is transferred in novel bioabsorbable polymer material exploitation.Natural protide high molecular material (such as collagen, gelatin,
Fibroin etc.) there is good biocompatibility and degradability, it is the emphasis of researchers' concern.Collagen electrospinning film has
Porosity is high, and the good advantage of water absorbing properties, can be used for clinical hemostasis material, (such as Cheng Weilu, Li Hui, He Jinmei are degradable compound
The preparation of hemostasis collagen protein sponge and biologic applications performance study [J] chemistry and bonding, 2016,38 (4): 231-234).In

Application [J] after pressed pipe in point of puncture hemostasis nurses journal .2015 (22): embodiment of 40-41.) and in tooth extraction wound stopping blooding
(Zhu Shaoping, Zhang Aiping sponeostan tooth extraction wound 290 effect observation [J] Shandong medicine .2003 (35) of hemostasis: 69-
69.) in, the simple of gelfoam hemostasis, economy and validity have obtained the approval of patient and medical staff.Sorada etc.
(Sorada K,Siriporn D,Juthamas R.Aninnovative bi-layered wound dressing made
of silk and gelatin for accelerated woundhealing.International Journal of
Pharmaceutics, 2012,436:141-153.) research fibroin albumen and gelatin bilayer hemostatic material and it is commercial only
Blood material promotes wound healing compared to that can significantly reduce wound area.However it is higher and higher to hemostatic material in medical field
Under performance requirement, the hemostatic material of protide still has that anthemorrhagic speed is slow, to the drawing ability and surface of a wound group of blood constituent
The shortcoming of poor adhesive force is knitted, therefore how to improve the anthemorrhagic speed of protide macromolecule hemostatic material, is allowed to when contacting wound
Coagulation factor can be quickly activated, the generation of fibrin ferment is accelerated, promoting the formation of sludged blood is the pass for opening up such material application
Key.
Some researches show that the surface charge of material can influence the selective absorption and sedimentation of albumen, promote blood coagulation system
Activation, the especially material with negative charged surface can be activated solidifying in blood coagulation system by its surface charge abundant
Blood factor Ⅻ, and the factor be cause one of key factor of intrinsic coagulation system starting (OstomelTA, ShiQ,

Studies have shown that its anthemorrhagic performance of methylated collagen positively charged by surface modification be greatly improved (Chen Lu,
Li Xia, Jiang Bo modify styptic activity research [J] China and foreign countries medical treatment .2013,32 (23): 130-131 of collagen).Protein is most
Important biology polarization high molecular material, has the ability (summer that can be stored real charge for a long time and (or) keep polarized state
Zhong Fu Biomaterials of Electret [J] material Leader .1994 (1): 48-52.).Under the action of high voltage electric field, carboxyl, amino
Equal charged groups tend to orderly polarization offset, and fetter the charge intensified in a large amount of electric fields, and fiber surface is made to form difference
Potential areas.Electrostatic spinning is a kind of nanofiber technology of preparing of simple process, relative to sponge hemostatic material, nanofiber
The material specific surface area of structure is bigger, more with the contact area of blood, and hemostatic composition is easier to adhesion and aggregation in fiber surface, from
And shorten bleeding stopping period, raising haemostatic effect (preparation of Liu Xuefeng wound hemostasis nano-fiber material and the Nanjing performance [D]:
Southeast China University, 2011:1-51).The polarization process of the presence of high-voltage electrostatic field and tunica fibrosa later what is more is also polarity material
Material provides polarization and captures charge offer may.
Protide high molecular material constructs a kind of molecular chain orientation arrangement by electrostatic spinning technique, and fiber surface distribution is more
The nano-fiber material of the three-dimensional microcosmic network structure of kind hydrophilic radical, then by polarization process, make material internal polarization orientation,
Surface is distributed polarization charge, so that absorption moisture that can be instantaneous in wound hemostasis, adsorbs blood constituent, increase in subrange
Fluid viscosity is healed, and quickly activates coagulation factor, accelerates the generation of fibrin ferment, promotes coagulation process, to improve material
Anthemorrhagic speed.Therefore the protide biological absorbable hemostatic material of this kind of energy quick-acting haemostatic powder is in terms of clinical medicine and hemostasis
There to be more significant advantage.
