Description
Technical field
The present invention relates to medicine and hygiene fields, relate in particular to a kind of outlet offset soft shell filter.
Background technology
Soft shell leukocyte depletion filter is increasingly favored in blood transfusion field be subject to user now.Leucocyte in blood exists
Leukocyte antibody may be produced after allogenic blood transfusions, causes a series of adverse reaction and side effect, such as：Non-hemolytic is sent out
Thermal response, Inefficacy of Platelets Transfusion, transfusion-associated graft versus host disease（GVHD）, cytomegalovirus（CMV）Infection etc..Cause
This, blood and its component remove leucocyte and are of great significance to transfusion safety and clinical treatment.Compared to duricrust filter,
Soft shell filter is to form two filter chambers using polymeric membrane heat seal, and blood is realized blood by the filter layer between two filter chambers
The separation of component.
But the production technology of current China soft shell filter is relatively rough, and as shown in Figure of description Fig. 1, Fig. 2, outlet leads to
When traditional handicraft is crossed with polymeric membrane heat seal, its both sides corresponds to the outermost film in filter layer both sides respectively, in filter chamber
Opening is corresponding filter layer median plane, therefore often because filter back cavity Import ＆ Export Department is squeezed be subject to filter layer, filter membrane at outlet
The problems such as pressing and causing obstruction, thrombosis.
The content of the invention
Goal of the invention：The object of the present invention is to provide a kind of improvement port of export and eliminate the outlet offset of detention space
Soft shell filter.
Technical solution：To achieve the above object, a kind of outlet offset soft shell filter of the invention, including filter layer,
Cephacoria, inlet tube, caudacoria, the outlet of filter layer both sides are distributed in, the caudacoria includes inner membrance and outer membrane after filter after filter, after filter
Inner membrance is the interior circular membrane along the outer heat seal of outer membrane after connection filter layer, outer and cephacoria and filter, between cephacoria and filter layer
Form filter ante-chamber and connected with inlet tube, form filter back cavity after filter after outer membrane, filter between inner membrance, filter membranous layer, outlet is opened on
Back cavity bottom is filtered, the side of outlet is connected with inner membrance heat seal after cephacoria, filter, opposite side and outer membrane heat seal after filter, relative to preceding
Outer membrane forms the cross section in space after film and filter, and the side of arrival end to the filter back cavity of outlet deviates.
Further, the deflected length is the 1/5 ~ 2/5 of outlet caliber.That is the opening at least 8/10 of outlet
Part is corresponding filter back cavity, it is ensured that the unobstructed blood for filtering back cavity is unimpededly exported from outlet.In order to enable outlet
Effective offset, a gasket is added in outlet close to the side of cephacoria, and gasket material is identical with polymeric membrane material therefor,
It is fixed by heat seal.
As the further optimization of the present invention, after the filter after outer membrane and filter inner membrance in outlet each side self-forming
One drainage trough, the lower end of two drainage troughs are not less than the outlet mouth of pipe.
Drainage trough of the present invention is collectively forming by the engaging portion in two faces and two faces, works as outlet
The part stretched into is long, will be higher by the lower end of drainage trough, causes that part blood is stranded in outlet and drainage trough is collectively forming
Detention space in.As a kind of preferred embodiment of the present invention, two drainage troughs form a continuous arc, cephacoria and caudacoria
The shape of nearly outlet pipe end is semicircle or half elliptic.As another preferred embodiment of the present invention, two drainage troughs form one
A V-shape, outlet V-shape lower end sharp corner, for this reason, cephacoria and caudacoria closely export the shape of pipe end and V-shape approaches.
Beneficial effect：The present invention has carried out careful improvement to existing soft shell filter outlets end, by outlet to after filter
The side offset of chamber is set, so as to ensure that outlet goes out liquid and do not produce obstruction and delay, reduces the waste of blood.

Embodiment
The present invention is further described below in conjunction with the accompanying drawings.
Embodiment 1
As shown in Figure 1 and Figure 2, a kind of 6 offset soft shell filter of outlet, including filter layer 1, it is distributed in 1 both sides of filter layer
Cephacoria 2, inlet tube 5, caudacoria, outlet 6, caudacoria include filter after inner membrance 3 and filter after outer membrane 4, after filter inner membrance 3 for it is interior along connect
The circular membrane of the outer heat seal of outer membrane 4 after filter layer 1, outer and cephacoria 2 and filter, forms filter ante-chamber between cephacoria 2 and filter layer 1
7 and connected with inlet tube 5, filter back cavity 8 is formed after filter after outer membrane 4, filter between inner membrance 3, filter membranous layer, after outlet 6 is opened on filter
8 bottom of chamber, the side of outlet 6 are connected with 3 heat seal of inner membrance after cephacoria 2, filter, opposite side and 4 heat seal of outer membrane after filter；Relative to preceding
Outer membrane 4 forms the cross section in space after film 2 and filter, and the side of arrival end to the filter back cavity 8 of outlet 6 deviates, deflected length
For the 1/5 ~ 2/5 of 6 caliber of outlet.That is the part of the opening at least 8/10 of outlet 6 is corresponding filter back cavity 8, it is ensured that
The unobstructed blood of filter back cavity 8 is unimpededly exported from outlet 6.In order to enable outlet 6 effectively to deviate, leaned in outlet 6
Nearby the side of film 2 adds a gasket 9, and 9 material of gasket is identical with polymeric membrane material therefor, is fixed by heat seal.
After filter after outer membrane 4 and filter inner membrance 3 in each side one drainage trough of self-forming of outlet 6, two drainage troughs
Lower end is not less than 6 mouth of pipe of outlet.Drainage trough is collectively forming by the engaging portion in two faces and two faces, and two are drawn
The shape of chute can be a continuous arc, and the shape at cephacoria 2 and nearly 6 end of outlet of caudacoria is semicircle or half elliptic；
Alternatively, two drainage troughs form a V-shape, sharp corner of the outlet 6 in V-shape lower end.
The above is only the preferred embodiment of the present invention, it should be pointed out that：For the ordinary skill people of the art
For member, various improvements and modifications may be made without departing from the principle of the present invention, these improvements and modifications also should
It is considered as protection scope of the present invention.
