Abstract
The invention discloses a blood filtration and transfusion bag with double layers of filter membranes, belonging to the field of medical appliances and relating to the blood filtration and transfusion technology. The blood filtration and transfusion bag with double layers of filter membranes is characterized by comprising two filter membrane bags with different filtration pores and different flat areas, wherein the small filter membrane bag is flatly put into the big filter membrane bag, a hose is led out from the opening of the small filter membrane bag, the two bag openings are in the same direction and superposed on two edges, and the corresponding edges are bonded and sealed; the filter membrane bags are flatly put into an outer bag which is coated with sodium citrate on the inner surface and is larger than the filter membrane bags, and the filter membrane bag openings and the outer bag opening are in the same direction, superposed and sealed; and an exhaust tube with a control plug is led out from the sealed outer bag opening, and a tube is led out from the bottom of the outer bag. The invention has the positive effects that: the inner surface of the thoracic blood transfusion bag is coated with the anticoagulant sodium citrate, and the two filter membrane bags with different pore diameters are put into the transfusion bag, therefore, harmful substances can be filtered maximally; and the thoracic blood transfusion bag can be applied on site for filtering and transfusing the thoracic blood, thereby solving the problem of blood shortage when a patient severely hemorrhages on site, and greatly reducing the mortality on site.
Description
Technical field
Belonging to medical instruments field, relate to blood filtration feedback technology, exactly is that a kind of blood filtration of double-deck filter membrane feeds back bagging apparatus.
Background technology
The hemothorax that causes because of chest opening or closed injury, all comparatively common in flat wartime, in recent years because the taking place frequently of thoracic trauma in the vehicle accident, such damage has the trend that increases day by day, and there is patient's blood loss of significant proportion bigger, need blood transfusion treatment or operation to open the breast hemostasis, first aid increases severely with blood and operation blood using amount, and blood source day is becoming tight.Especially the propagation that rare blood type blood supply difficulty, expense raise and the allosome blood transfusion may bring untoward reaction and infectious disease makes and reclaims thoracic cavity blood and feed back from body and more and more come into one's own in thoracic surgery.But utilize simple and easy retracting device to carry out from aspect the body breast blood feedback behind thoracic trauma, remaining at some has problem to be solved.
Breast blood recovery type autotransfusion (ATS) be with in patient's art, the postoperative thoracic cavity is hemorrhage or wound hemothorax recycling after feed back from body again.ATS was divided in the art by the processing time and postoperative blood reclaims and three kinds of traumatic hemorrhage; Be divided into two kinds of non-washing type and washing types by processing mode.What clinical practice at present was more all is hemoconcentrator, and it makes blood flow through the macromolecule filter membrane, and albumen that molecular weight is big in the blood and visible component (hemocyte etc.) tunicle is held back; Lower-molecular substances such as electrolyte, blood urea nitrogen, creatinine then discharge from blood, and the blood recovery that has concentrated is given patient.It is applicable to that the control blood cell overstocks in extracorporeal circulation, the open heart operations process degree, art finish deviating from of moisture content; The dehydration therapy that also can be used for congestive heart failure, pulmonary edema and poor kidney person.External present hemoconcentrator has 1. U.S. Minntech HPH hemoconcentrator, and it is raw material with the polysulfones, maximum effective film area 1.3m2, maximum transmembrane pressure 500mmHg; 2. Japanese Terumo CX hemoconcentrator, it is raw material with the polypropylene, maximum effective film area 1.1m2, maximum transmembrane pressure 500mmHg; 3. the Diafilter hemoconcentrator of U.S. Amicon need not the mechanical assistance pump, drive by the human body self blood pressure and get final product water outlet, and volume is little.But generally speaking, the hemoconcentrator volume is bigger, can only be applied to hospital operating room, can not carry out the blood recovery at wound scene, therefore is not suitable for the line treatment at wound scene.
Carried out certain research though feed back device for portable simple and easy breast blood at present both at home and abroad, but it is still more limited, domesticly developed a kind of breast that can the site of deployment first aid and learn and feed back bag in repairing justice etc., its action principle is exactly to place one deck filter membrane in storage blood bag central authorities, but its shortcoming is that membrane pore size is single, can only be at the filtration of part material, its contact surface is less in addition, occurs the obstruction of filter opening easily.
Generally speaking, up to the present, also there is not a kind of portable simple breast blood of satisfaction to feed back the line treatment that bag can be used the wound scene.
Summary of the invention
It is little to the invention provides a kind of volume, in light weight, can fold the blood filtration feedback bag that carries and be applied to a kind of double-deck filter membrane of on-the-spot line treatment.
The technical scheme that the present invention takes::
A kind of blood filtration of double-deck filter membrane feeds back bag, comprises the filter membrane bag, and its scheme is: the filter membrane bag is with for small one and large one two of the smooth area of different filter openings; The flat plug of little filter membrane bag is in big filter membrane bag, and a flexible pipe is outwards drawn at the place by little filter membrane bag mouth, two bag mouth direction unanimities, and both sides overlap, the matched edge adhesive seal; There is big filter opening on the little filter membrane bag surface of internal layer, and there is little filter opening on outer big filter membrane bag surface; The flat plug of filter membrane bag in inner surface covers the big outer bag than filter membrane bag of sodium citrate, filter membrane bag mouth and consistent, the coincidence of outer bag mouth direction, and seal; Bag mouth has the exhaustor of drawing band control plug outside sealing, and there is a fairlead at the outer bag end.
Good effect behind enforcement the present invention is:
This breast blood feeds back the bag inner surface and scribbles the anticoagulant sodium citrate, the filter membrane bag that has two-layer different pore sizes in addition in it, filtering out harmful matter to greatest extent, simultaneously because contact area is bigger, therefore be not easy to stop up filter opening, it can be used for the patient of massive blood loss at the scene, and its breast blood is filtered the back feedback, solve on-the-spot massive blood loss patient situation of " blood famine " when occurring, reduce on-the-spot mortality rate greatly.

The specific embodiment
Now the invention will be further described in conjunction with the accompanying drawings
A kind of blood filtration of double-deck filter membrane feeds back bag, comprises the filter membrane bag, and its formation is: the filter membrane bag is with for small one and large one two of the smooth area of different filter openings; Little filter membrane bag 1 flat plug is outwards drawn a flexible pipe 3, two bag mouth direction unanimities by little filter membrane bag mouth place in big filter membrane bag 2, both sides overlap, the matched edge adhesive seal; There is big filter opening 4 on the little filter membrane bag surface of internal layer, and there is little filter opening 5 on outer big filter membrane bag surface; The flat plug of filter membrane bag in inner surface covers the big outer bag 7 than filter membrane bag of sodium citrate 6, filter membrane bag mouth and consistent, the coincidence of outer bag mouth direction, and seal; Bag mouth has the exhaustor 9 of drawing band control plug 8 outside sealing, and there is a fairlead 10 at the outer bag end.
