Description
Technical field
The invention belongs to medical instruments fields, and in particular to a kind of injection-type hemostasis device.
Background technology
First aid is stopped blooding the massive haemorrhage caused by wound, such as not in time stop blooding and wrapping, can seriously threat people
Health or even life.
Currently used first aid Hemostasis is tourniquet hemostasis, hemostasis with packs.Tourniquet hemostasis refers to bandage, triangle
Towel, tourniquet and other items directly apply the treatment measures in wound or a certain position of ligation.Hemostasis with packs is with first-aid dressing, cotton pad
Or the gauze of disinfection is packed in wound, then wrapped up with pressure dressing, for thigh root, armpit, shoulder, mouth, nose, uterine cavity etc.
The bleeding at position.These are all common simple Hemostasis, often invalid to some complicated wounds, and are be easy to cause follow-up
It is much bothered in course of wound treatment.In recent years, international and domestic all in research first aid hemostasia products, including civilian and war wound emergency treatment
Etc. application.
The chitosan class hemostasia products applied in the market mainly have styptic powder, chitosan coat bandage, styptic sponge class, stop
Blood gauze class, such product body is interior and body surface hemostasia products all have, and is applied to body surface mostly and stops blooding, because of chitosan main source
It is extracted for shrimp and crab shells, there is many prawn crab allergic human populations, and complicated component in extraction process, itself be also animal derived production
Product have the risk that heterologus virus infects.There are many adverse events in the material product application process in recent years.
Common hemostatic material is zeolite powder in previous first aid procedures, and advantageous feature is：Haemostatic effect is good, bleeding stopping period
It is short；Low production cost；Property is stable and easy to carry etc. at room temperature.But its defect is hemostasis while having exothermic reaction, no
Easy-clear residual particles cause visceral organ injury, cicatrization.The zeolite powder of modified form is packed with non-woven bag, avoids residual
Damage of the particle to internal organs etc., its haemostatic effect drastically decline, although and its exothermic reaction by improvement, effect is but still
Right unobvious.
In first aid application process, previous hemostasia products highlight many problems in use, are badly in need of now
A kind of effect is good, damage is small, applied to having a cavity wound, especially joint binding site, such as groin, armpit position only
Blood, such position can not use physical hemostasis, the i.e. hemostasis by compression of tourniquet.And it was being used in hemostasis in vivo
Cheng Zhonghui is more painful, without complementary resolution policy.In addition, the push rod stated in existing injection-type hemostasis device patent is in material
It is outer tension state after material molding, disadvantage is：1) simple structure, stability are poor；2) entire product size is increased, packaging increases,
And the requirement to packaging is high, carries and storage is all inconvenient；3) aseptic process is not carried out, easily causes wound infection.Therefore, existing
There is product that cannot all meet first aid demand.
