Abstract
The utility model discloses a blood filter is with ending contrary pellosil lamella, including the holding ring, be provided with to anchor ring one side pellosil protrudingly between the inner edge anchor ring of holding ring, the bellied outline of pellosil is segment shape, is provided with a plurality of openings to extension all around by pellosil bellied protruding summit, and a plurality of membrane lamella is cut apart into with the pellosil arch to a plurality of openings. This blood filter is with ending contrary pellosil lamella simple structure, is provided with to anchor ring one side pellosil protrudingly between the inner edge anchor ring of holding ring, and by the blood of internal derivation because the effect of blood pressure, the opening that will end between the contrary pellosil lamella is opened, and blood gets into subsequent dialysis route, when patient's blood pressure is lower, reduce the impact force of membrane lamella, the pellosil lamella is closed, and the journey time -out is filtered to blood.
Description
Technical field
This utility model relates to medical product field, is specifically related to the non-return pellosil lobe of a kind of blood filter.
Background technology
Blood filtration has become irreplaceable treatment means in Treatment, and blood filter also becomes one of indispensable armarium of modern hospital simultaneously.Blood filter clinical practice excess moisture in purged body, purged body intracellular metabolite refuse, poisonous substance, correct Electrolyte imbalance, guarantee nutritional support, promotes graft function and remove various cytokine, inflammatory mediator.Can be used for: various cardiovascular function instability, Metabolism or companion cerebral edema acute and chronic renal failure, and Multiple Organ Dysfunction Syndrome, adult respiratory distress syndrome, crush syndrome, acute necrotizing pancreatitis, chronic heart failure, hepatic encephalopathy, the treatment of medicine and toxic poisoning etc., for serious symptom treatment provides new treatment means.Blood filter of the prior art mainly comprises following structure: blood extracorporeal circulation system, waste liquid transit system, dialysis solution peripheral passage system.Blood is derived external, through the poisonous material of extracorporeal circulation system by filter from blood by filtering, the blood removing toxin returns in patient body.Blood transports the start and stop of parts and mainly relies on venous clamp pressure-detecting device to realize automatically controlling, and can cause pressure alarm when deriving external blood pressure and being low, but immature due to software and hardware, exist because pressure drift problem causes the phenomenon of warning.Therefore, need to realize realizing controlling to the pressure of blood filter blood extracorporeal circulation system from the angle of frame for movement.
Utility model content
The purpose of this utility model is to overcome the defect existed in prior art, provides the non-return pellosil lobe of blood filter that a kind of structure is simple, sensitive to both sides blood pressure response.
For realizing above-mentioned technique effect, the technical solution of the utility model is: the non-return pellosil lobe of a kind of blood filter, it is characterized in that, comprise locating ring, be provided with to anchor ring side pellosil protruding between the inner edge anchor ring of described locating ring, the outline of pellosil projection is segment-shaped or ellipse segment-shaped, and have some openings by the convex apexes of pellosil projection to surrounding is extended, pellosil projection is divided into several film lobes by some openings.
Preferred technical scheme is, for integral type is connected between described locating ring with pellosil projection.Locating ring is that silica gel material can also ensure itself and check (non-return) valve stable connection.
Preferred technical scheme is, the outline of pellosil projection is segment-shaped, and segment height corresponding to pellosil convex inner surface is less than or equal to the radius of place sphere.
Preferred technical scheme is, pellosil projection is evenly divided into 3 ~ 6 film lobes by opening.Film lobe is crossed film lobe at least and is opened too small by blood pressure effect, and film lobe is crossed and may be caused flexible single film lobe turnover at most and not easily reset, and then forms gap or through hole in pellosil projection, cannot realize non-return effect.
In order to optimize film lobe open and close angle further, preferred technical scheme is, described opening combinations across, and pellosil projection is divided into four film lobes by cross-shaped aperture.
Preferred technical scheme is, the arc length of single opening is greater than 1/3rd of arc length between convex apexes to locating ring place plane, and the other end of opening is positioned in pellosil projection.Opening length can affect the closed seal degree of film lobe reset and be subject to blood pressure effect opening degree.
Preferred technical scheme is that the arc length of single opening is greater than 1/2nd of arc length between convex apexes to locating ring place plane further.
Advantage of the present utility model and beneficial effect are:
This blood filter is simple with non-return pellosil valve structure, be provided with to anchor ring side pellosil protruding between the inner edge anchor ring of locating ring, by the effect of the blood of deriving in body due to blood pressure, opened by the opening between non-return pellosil lobe, blood enters follow-up dialyzing access; When patients' blood is lower, reduce the impulsive force of film lobe, pellosil lobe closes, and blood filters journey and suspends.

Detailed description of the invention
Below in conjunction with drawings and Examples, detailed description of the invention of the present utility model is further described.Following examples only for clearly the technical solution of the utility model being described, and can not limit protection domain of the present utility model with this.
Embodiment 1
As depicted in figs. 1 and 2, the non-return pellosil lobe of blood filter of embodiment 1, comprise locating ring 1, be provided with between the inner edge anchor ring of locating ring 1 to anchor ring side pellosil projection 2, the outline of pellosil projection 2 is segment-shaped, have some openings 3 by the convex apexes of pellosil projection 2 to surrounding is extended, pellosil projection 2 is divided into several film lobes by some openings 3.
For integral type is connected between locating ring 1 with pellosil projection 2; The outline of pellosil projection 2 is segment-shaped, and the segment height that protruding 2 inner surfacies of pellosil are corresponding is less than the radius of place sphere.
In the present embodiment, some openings 3 are combined into cross, and pellosil projection 2 is evenly divided into four film lobes by cross-shaped aperture.
