Description
Technical field
Hemostatic material in medical use technical field is the utility model is related to, more particularly to a kind of first aid bleeding-stopping dressing.
Background technology
Emergency treatment to the sudden accident in daily life, in hospital the wound in the surgical procedure of patient is stopped
Effective quick-acting haemostatic powder of the rescue of injured soldier and patient's part is very important in blood, war, because uncontrolled
Bleeding is to cause massive haemorrhage or battlefield main causes of death in burst accident, medical operating.
The main purpose of wound first aid is temporary control bleeding, covering is bound up a wound as early as possible, and wound is isolated from the outside
To reduce infection chance, good surface of a wound condition is created for debridement.Traditional wound hemostasis material is mainly first-aid dressing, four-head
Band, tourniquet and bandage etc., the deficiency that also a large amount of aseptic dressings stop blooding for making up first-aid dressing wrapping sometimes.It is a large amount of sterile deposited
Material is difficult to carry and sterilizes preservation；First-aid dressing and four-tailed bandage only have sterile triangle bandage and 1~2 block of medium and small dressing, to large area
Wound and combined injury, the covering of multiple injury wound, haemostatic effect is not good enough.
Into the 90's of last century, several wars have continuously been started by U.S. army, and soldier's injures and deaths on battlefield make the high-rise meaning of U.S. army
Know the importance of massive haemorrhage quick-acting haemostatic powder, thus put into huge fund, carry out the development of new rapid hemostatic material.Past 10
Nian Jian, America and Europe have developed the first aid hemostasis that several hemostatic materials are used for massive haemorrhage in succession.And during the country is used at present, severe goes out
The quick-acting haemostatic powder product of blood is few, and conventional styptic has tourniquet, gauze and Yunnan Baiyao etc., and they are in, severe goes out
The quick-acting haemostatic powder effect of blood is limited.Therefore, exploitation is easy to carry about with one, the new wound that has good haemostatic effect to large area wound stops
Blood material has turned into focus in recent years.
Chitosan is de-acetyl chitin product, is unique a kind of positively charged in the nature found so far
Natural activity polysaccharide, can form blood clot by adsorbing and assembling negatively charged red blood cell and reach significant haemostatic effect.
It has good biocompatibility and biodegradability, and there is antibacterial, anti-inflammatory, the reduction surface of a wound to ooze out and promote wound tissue
Regeneration, repair, the effect of healing, and there is good pliability, water imbibition and gas permeability, be the important money of Wound dressing
Source.Various shapes can also be made in chitosan, such as powdered, fibrous, spongy, gel, film-form, foam-like
Deng；Can also be compound with one or more of other high polymer materials, by introduce other high polymer materials or addition medicine with
Improve the performance of chitosan product.Chitosan-phospholipid complex has excellent hemostatic function, plus their intrinsic spies
Property --- nontoxic, no antigen, and with biocompatibility, bacteriostatic activity, promotion wound healing etc., assign it and be used as hemostatic material
The superperformance of material.
Patent US20090186851A1, WO2009130485 describe a kind of graininess chitosan hemostatic material, the material
The products C elox styptic powders of formation also show that good haemostatic effect to main artery bleeding, but it is due to hemostasis granules shape matter
Amount it is lighter, in actual applications, particularly the wounded save oneself use when exist in-convenience in use, it is not easy to reach blutpunkte, imitate
Fruit is difficult to the potential risk played.
CN102648985B also discloses that a kind of Chitosan first aid hemostatic material, has at least double-layer structure：Upper strata is shell
Glycan hemostatic layer, its structure are porous microsphere, porous fibre, mandruka, or the complex of this several type；Lower floor is polypropylene
Sour grafted chitosan laying, its structure are porous fibre or mandruka, or the complex of both types.The hemostatic material
Although the defects of customer service is difficult to reach blutpunkte, it is easily caused bleeds profusely, and blood and/or wound fluid hold
Hemostatic material is easily passed through, pollutes surrounding skin or clothes.
Utility model content
The purpose of this utility model is the deficiency for existing hemostatic material, there is provided it is a kind of easily and fast, efficient first aid
Hemostatic material, especially bled profusely to caused by the accidents such as outdoor sports, traffic accident, the effect of quick-acting haemostatic powder can be played
Fruit.
