Description
Technical field
The present invention relates to a kind of self-locking type fast hemostatic device, belong to technical field of medical instruments.
Background technology
The limbs arteriovenous that tradition is bigger is hemorrhage, and for the sake of transporting wounded's convenience, frequently with tourniquet method,
Tourniquet is used should strictly to grasp appropriateness main points, as Zha get Tai is tight, overlong time, all can cause soft tissue
Compressing necrosis, far-end of limb poor arterial inflow, amyotrophy, even produce crush syndrome, if pricked
Not tight, arterial distal still has blood flow, and the backflow of vein is obstructed completely, causes wound bleeding more on the contrary.
It is hemorrhage that tourniquet method can prevent extremity effectively.But with rear big to tissue injury, may cause or add
The weight complication such as acral necrosis, acute renal insufficiency.
Therefore, for exploring the most effectively hemostatic technique, it is proposed that the present invention, have according to puncture site
Hemostasis operation targetedly, can effectively prevent skin from strangling crushing wound, because intravascular coagulation causes obstruction, i.e.
Making to unclamp tourniquet can not the problem such as recovery organization blood supply again.
Summary of the invention
The technical problem to be solved is to provide a kind of compact conformation, it is simple to carry, pressure adjustable,
Accurate positioning, hemostasis are quickly effectively, to be easy to medical worker's operation, the damage of patient body puncture site little
Self-locking type fast hemostatic device.
The technical scheme is that a kind of self-locking type fast hemostatic device, its
It is characterised by: include hold assembly, latching member and unlocking feature；
Described hold assembly, has the effect of equilibrium clamping wound both sides skin closure, can effective compressive trauma
Mouth peripheral vessels；
Described latching member, it is ensured that use self-locking type fast hemostatic device one way engagement to rotate；
Described unlocking feature, fast quick-detach self-locking type fast hemostatic device during the rescue and treatment of the wounded.
The invention has the beneficial effects as follows, whole operation is completed by medical personnel one people, can promote after using
Blood coagulation, closes wound, reduces the amount of bleeding of patient, reduces the chance that antibacterial infects, is particularly well-suited to relatively
Difficult enforcement hemostasis by compression, the thorax abdomen wound of tourniquet hemostasis.This apparatus is used for pre hospital care wound hemostasis,
Therapeutic time can be shortened, reach the most effectively hemostasis, reduce the effect of Infective morbidity.
On the basis of technique scheme, the present invention can also do following improvement.
Further, described hold assembly includes right clamping plate, left clamping plate and engagement pin；Described engagement pin is embedded in
On right clamping plate and left clamping plate, being used for engaging wound both sides skin, described right clamping plate are inlaid in ratchet outside the right side
Above and link with it；Left clamping plate are inlaid on left outside ratchet and link with it.
Using above-mentioned further scheme to provide the benefit that, engagement pin can make the skin equilibrium of wound both sides be subject to
Power, forms local blood pool, promotes the laminating hemostasis of the solidification of blood, beneficially wound.
Further, described latching member include left outside ratchet, left inside ratchet, right outer ratchet, right handle ratchet wheel,
Rotating shaft, shaft end ring and spring；Described left outside ratchet and left inside ratchet are mutual under the pressure effect of spring
Engagement one-directional rotation；Outside the described right side, ratchet and right handle ratchet wheel engage each other unidirectional under the pressure effect of spring
Rotate；Ratchet and left inside ratchet and right handle ratchet wheel engagement rotation in opposite directions outside described left outside ratchet and the right side.
Above-mentioned further scheme is used to provide the benefit that, it is ensured that right clamping plate and left clamping plate are to wound skin
Clamping anastalsis.
Further, described unlocking feature includes dropout push rod, dropout stud；Described dropout stud is by rotation
Enter outside left outside ratchet and the right side in ratchet guide groove, promote dropout push rod to separate left outside ratchet and left inside ratchet, right
Outer ratchet and the engagement of right handle ratchet wheel, thus open right clamping plate and left clamping plate.
Use above-mentioned further scheme to provide the benefit that, be conducive to relief during save time, laborsaving, behaviour
Make efficient quick, avoid skin to damage further.
Further, described right clamping plate and left clamping plate use light plastic molded, and upper surface is embedded medical
Sewing needle.
Using above-mentioned further scheme to provide the benefit that, overall performance is reliable, closer in buman body type
Change.
