A kind of biological adhesive type stasis-eliminating hot compressing bag
Technical field
This utility model belongs to technical field of medical instruments, relates to the medical bio adhesive type stasis-eliminating hot compressing bag that contains the medical cloth of hirudin coating PVC.
Background technology
Be easy to generate subcutaneous extvavasated blood clinical vein blood sampling, transfusion back and physical property traumatic injury, gouge patient, cause local subcutaneous tissue and swelling pain occurs, influence limb function, severe patient can cause cutaneous necrosis, increase the patient suffering, and cause easily conflicting of nursing staff and patient.Need 2-4 week just can disappear generally speaking.Common way is with hot towel hot compress.The shortcoming of this way: 1, the variations in temperature of hot compress method such as hot towel is wayward.2, the temperature leak of hot towel comparatively fast can not keep uniform temperature for a long time.3, simple physiotherapy effect is undesirable.4, the hot compress time is not enough.Other way is a moisten compress therapy, is meant with the gauze dip in liquid medicine to apply a kind of method that disease is treated in the affected part.This method has effects such as suppressing to ooze out, to restrain antipruritic, reducing swelling and alleviating pain, control infection, promotion skin healing.For example the soak gauze that Adlerika is soaked spreads on the affected part, or the doctor gives the patient with the Adlerika and the gauze that prepare, enjoins gauze foldingly, spreads on the affected part after soaking with Adlerika.This way needs the doctor to make detailed description and interpretation on the one hand, and the patient carries and use equal inconvenience on the other hand; The used Adlerika of what is more important, gauze, utensil etc. can not guarantee to operate under the environmental condition of cleaning, cause bacteria attack easily, cause the infection in affected part, have increased the weight of patient's misery.
Hirudin is a kind of active substance of separating from the Hirudo salivary gland, has the effect that stops blood coagulation, and its mechanism is to cause the thrombin inactivation by the conjugated group of thrombin substrate in the occlude blood.The single chain polypeptide that hirudin is made up of 65 aminoacid, because trematodiasis kind difference, it is also different to contain the aminoacid number, majority contains 65 aminoacid, also there are some to contain 64 to 69 aminoacid, wherein the content of glutamine and N is higher, and relative molecular mass is 7000D, and isoelectric point, IP p I is 3.8.3 disulfide bond are arranged, and disulfide bond plays an important role for the stability of molecular configuration, is the key that keeps high anticoagulating active.At present, 7 kinds of isomers have been isolated.Hirudin is the most effective known natural anticoagulant, can effective anti-blood clotting, multiple thrombus disease such as phlebothrombosis, disseminated inravascular coagulation, brain blood coagulation, thrombophlebitis and crown arterial thrombus all there are prevention and therapeutic effect, particularly the thromboembolism again that reaches behind the surgical operation after dark bolt is treated are had important prevention and therapeutic effect.Therefore, hirudin will become the antithrombotic medicine of new anticoagulation.In at first finding the extract of Hirudo, Haycraft in 1884 contains anticoagulative substance, the pure product of isolating this anticoagulative substance of nineteen fifty-seven Markwardt success from Hirudo, and called after hirudin.Extract natural hirudin, because the restriction of raw material finite sum extracting method yields poorly it, the cost height has limited its clinical practice.
Foreign medical science blood transfusion and 1993 the 16th volumes of blood fascicle the 6th phase record Chinese Academy of Medical Sciences Blood Research Institute, Guo Juan summary Wang Hebi examines and revises " progress of lepirudin 023 ludon " Haycraft and found in the Hementaria officianalis extract anticoagulant substances is arranged in 1884.At the end of the fifties, Markwardt isolates pure product first, called after hirudin (Hirudin), and know that it is the special inhibitor of thrombin, be a kind of ideal anticoagulant, antithrombotic preparation.Learn its structure and amino acid sequence the beginning of the eighties.Loaded down with trivial details because of the natural hirudin extraction step, and raise the Hirudo difficulty, the Hirudo source is deficient, is difficult to obtain the pure product of q.s, and research and clinical practice are restricted.In recent years, the development of technique for gene engineering has remedied this defective, utilize chemosynthesis, cDNA library, PCR method to obtain gene clone, express and obtain lepirudin 023 ludon, thereby pharmacology, pharmacodynamics and the toxicity etc. of hirudin have more in depth been studied, a large amount of zooperies and clinic trial have been accelerated hirudin and have been applied to clinical process.At present, our laboratory is carrying out the research of HV1 cloning and expression.
Along with the molecular biology develop rapidly, external at present existing tens companies develop lepirudin 023 ludon and the plain preparation of functional Hirudo, a large number of experiments show that recombinant products is similar to natural prodcuts, are effective anticoagulant and antithrombotic preparation.The clinical indication of lepirudin 023 ludon can be summarized as follows: 1) clinical laboratory's anticoagulant; 2) internal medicine anticoagulant; 3) adjuvant of thrombolytic drug; 4) anticoagulant of angioplasty; 5) anticoagulant etc. in the hemodialysis.On the experimentation basis, carrying out clinical bulge test (as subacute and chronic DIC) at present.
The utility model content
In order to solve as above problem; the purpose of this utility model provides a kind of biological adhesive type stasis-eliminating hot compressing bag; it is by sealing bags (6) inner chamber medical PVC adhesive bandage adhesive plaster (1) to be set; post the medical cloth of hirudin coating PVC (2) in the front of adhesive bandage adhesive plaster; on the medical cloth of hirudin coating PVC, be coated with self-adhesive protection stick (3), (4), paste hot compress bag (5) at the back side of medical PVC adhesive bandage adhesive plaster (1) and constitute.
Biological adhesive type stasis-eliminating hot compressing bag described in the utility model is characterized in that the described medical cloth of hirudin coating PVC (2) is the 1-5mg hirudin that contains the about 7000D of molecular weight.
Biological adhesive type stasis-eliminating hot compressing bag described in the utility model, wherein the medical cloth of hirudin coating PVC (2) is medical adhesive-bonded fabric.
Biological adhesive type stasis-eliminating hot compressing bag described in the utility model, wherein sealing bags (6) is aluminium foil bag, medical plastic bag, the soft bag of composite membrane, hot co-extruded film soft bag or polrvinyl chloride bag.
Biological adhesive type stasis-eliminating hot compressing bag described in the utility model sticks hot compress bag at the medical band-aid adhesive plaster back side, helps the hirudin fast skin and absorbs, and hot compress promotes that also subcutaneous hemorrhage disappears fast in addition.Its benefit is:
1, hirudin has good blood stasis dispelling, blood coagulation resisting function.
2, hirudin can see through skin and directly affact the congestion place, performance hirudin anticoagulant blood maximum efficiency.
3, heat to local skin by hot compress bag, make subcutaneous extvavasated blood to dissipate fast.
4, hot compress bag has characteristics such as temperature constant, variations in temperature is very little, the hot compress time is long.
5, the use in conjunction of hirudin and hot compress bag can really accomplish to remove safely, fast, effectively, easily the effect of congestion than the remarkable enhancing of effect of the hot towel of simple application.
Hot compress bag described in the utility model has commercially available, its hot compress bag principle:
(1) the hot compress bag liberated heat is to have utilized the oxidized liberated heat of ferrum.
(2) carbon dust mainly acts on and is and ferrum and sodium chloride formation galvanic element, and ferrum is made negative pole, and carbon dust is done anodal.
(3) reaction equation in the entire reaction course is as follows:
2Fe-2e-==2Fe
