Abstract
A hemostatic agent delivery system includes a hemostatic agent which is inert and non-reactive yet is capable of forming a stable clot when applied to an actively bleeding wound. The system also includes a delivery assembly to structure to facilitate delivery of the hemostatic agent proximate the hemorrhage site. More specifically, the delivery assembly is structured to releasably contain the hemostatic agent via a release member which is disposed in cooperative relation with a support member which contains the amount of the hemostatic agent. The release member is structured of a soluble material such that it will at least partially dissolve and release the hemostatic agent upon disposition proximate the hemorrhage site. The delivery assembly further comprises a handle member structured to facilitate delivery of the hemostatic agent to the hemorrhage site.
Description
Background of the present invention
Prioity claim
The application of this priority and statement are made according to U.S.'s Immigration and Nationality Act the 119th (e) bar.Just in United States Patent (USP) trademark office audit, its flowing water is 60/757,459 to this temporary patent application now, and the submission date is on January 9th, 2006.
Invention field
The present invention seeks to include the hemostatic agent delivery system that applies accessory, and there are the sack or the container that load hemorrhage in system.This sack or container be minimum wants the local releasing unit that a support member connects same covering with the soluble material manufacturing that define.The another one characteristics are, hemostatic agent delivery system is a structure that is directly used in hemorrhage source, and hemorrhage can concentrate in this position and rest on hemorrhage source to become grumeleuse and termination is hemorrhage.

People know for a long time
And if be proved injured back go out hyperhematosis and don't fast or appropriate location comprehend and cause death.Unfortunately, collect the existence that the data that get are confirming this situation always in armed conflict.For example have 2,500 soldiers to die from the wound that is subjected to severe trauma in the Vietnam War, reason is pure to be to bleed till death.Military-specific data shows that also nearly 50% battle casualty is bleed to death, and great majority are dead in 30 minutes in injured back.Have report to show that this has 60% in first death in 5 minutes in 50%, and other there not be the people that accept suitably processing to die from one hour yet.
In addition, there are every year 70000000 people of surpassing to enter casualty department because of bleeding according to estimates.The same with the above, injured in the war, hemorrhage or acute hemorrhage is the principal element that causes traumatic death in population among the people.
Therefore, clearly fast and effectively control over bleeding just can save life.Satisfy this fast and effectively demand of control over bleeding for repaying examination, the result has developed various so-called tourniquet bandages and other products to provide quick control hemorrhage effectiveness.
In the middle of a kind of granular zeolite grain material product of taking from volcano lava stone that includes is arranged.This material is the hydrone in its meeting absorbing blood when being put in bleeding wounds, so just can produce the platelet aggregation that promotes blood coagulation.Even so, find in the observation that a kind of highly exothermic reactions can appear in the absorption process of this kind zeolite, thereby can produce quite big heating power, believe this minimum be partly to be because due to the iron content reaction of zeolite.Brighter ground really, there is report to point out to use this kind material temperature Celsius 90 ° to 100 ℃ can occur afterwards, thereby can cause that the Irak people who accepts the wounded soldier of this kind treatment and manage this product the second degree burn situation is arranged, must accept training and can manage this kind product even manage the personnel of this product through authentication.
It is that the packing of zeolite material just simply is poured on the open wound that another of this product crossed shortcoming, but for any serious hemorrhage situation about for example being cut because of aorta, the pressure of blood outflow wound can cause clearly that the coagulability of this material in this position dissipates so that effectiveness lowers and/or remove.And another disadvantage of this product be the zeolite material is a group graininess matter, in case when the wounded is sent to operating room or implements other such treatment, for example inject with commonsense method and/or absorption can be difficult to this material is removed from the wound supernatant in wound.
Another kind of product is then made with spherical chitosan, and this kind material is taken from the first shell of shell class animal.To be full of weighing apparatus prominent in report about the control over bleeding effectiveness of this material, under the situation especially for the wounded's hypothermia, for example is situation about may suffer a shock after losing blood seriously, and reports that its effectiveness can reduce or disappear greatly.In addition, other reports that product has incorrect operating position, for example is to use the product mouth of causing injury and do not touch the active surface of product owing to reversing.Because this product is taken from organic-biological, its shelf life life is very limited, during this period of time maybe can use, and maybe need discard, and that cost of just making each product is quite high, and this is a quite disadvantageous condition.
Another kind of tourniquet bandage is made by unicellular algae, and product includes chitosan.The structure of this product is to make things convenient for user only to need a small amount of training just can be fast and effectively control and/or stop the hemorrhage of severe trauma.Its another special feature when material touches blood, it is said that it can be assembled and activation by stimulating platelet, and that will cause that health divides the secret thromboxane that stimulates near the blood vessel compression of wound.Different sayings are that the chitosan material quickens normal condensation process with the effect of catalyst, thereby has quickened the hemorrhage control of health.Equally, because this product is taken from organic-biological, shelf life is very limited, maybe can use in during this period of time, maybe need discard.In addition, under the example of above-mentioned the wounded's hypothermia, its effectiveness is suspicious.
Another kind of material is directly to put wound into through structure with what use, the synthetic made from potato starch.It is said that this molecule is condensed into gel to the blood solids of wound circumference and solidifies with promotion, thereby the acceleration nature condenses.Characteristics wherein are to be set in synthetic potato starch product surface than macromole in the blood constituent.Observe thus and find that this also is the material of powder-form, use the utensil of a corrugated tube shape directly to annotate on wound.As above-mentioned zeolite material, if the situation of bleeding profusely is to be risen by incised wound because of main tremulous pulse, the pressure that blood flows out wound can be enough to powder is dispersed, be exactly that wound is covered by the binder of standard, and oneself exerts pressure when applying synthetic potato starchy material, and material still can dissipate in the coagulability of this position.
But also have another kind of by hydrophilic polymer and potassium salt in conjunction with the powder that with cattle only be basic hemopexin material, this kind powder it is said and can stop to export that central the need covers with binder when the various slight wounds research of contact.But as the product of above-mentioned direct " injection " wound, when being used for severe haemorrhage, the pressure of blood itself also can disperse this product, and that will subtract the end or eliminate itself hemostatic intention effectiveness.
Situation clearly provide quick, an effective and high hemorrhage control efficiency to comprise that the system of main arterial hemorrhage situation can bring great benefit, and this system just can suitably be used by the personage who only accepts a little training in view of the above.Its another one characteristics are to have to use one can directly inject suitable hemorrhage deal to wound, also provide one to be maintained at wound and to use the benefit of effective hemorrhage deal with the system of the mechanism of control over bleeding simultaneously.Simultaneously, if this kind system includes when can not produce the reaction and the hemorrhage of tool low irritability when wound uses just more favourable.In addition, the hemorrhage that is used in this system can promote blood coagulation in not producing under the response situation, that is to say the situation that can not have blood exothermic reaction and local heating at wound.And another kind of vantage provides a system that includes inorganic hemorrhage, and that just can be obtained and have or not the benefit of limitting shelf life.
The present invention's summary
The present invention seeks a hemostatic agent delivery system, and its structure is directly in hemorrhage position, and for example the tremulous pulse that is hurt applies hemorrhage, thereby blood vessels are condensed and stops wound bleeding.Therefore, hemostatic agent delivery system structure of the present invention further concentrates and rest on hemorrhage position to hemorrhage, and is same, and this function also is clotted blood and stops hemorrhage.
The rarest a kind of embodiment of hemostatic agent delivery system of the present invention is that to include minimum a kind of hemorrhage be the hemorrhage that blood clotting is constructed.Its another special feature is the rarest a kind of montmorillonitic clay material that includes among the present invention; In the middle of the rarest further embodiment, HECTABRITE DP is to do hemorrhage.The present invention includes clay material, or use separately, or use in conjunction with one or more additives as hemorrhage, can be in following discussion.
