Description
Technical field
This utility model relates to a kind of blood filter, is specifically related to a kind of blood nucleated cell and purifies filter.
Background technology
The autoblood recovery has not been a new noun concerning much human in the art; It mainly mixes autoblood in the suction storage blood jar through vacuum suction with a certain amount of heparin; Concentrate in the container handling (Centrifuge Cup) erythrocyte is centrifugal through high speed centrifugation, lighter material (blood plasma, thrombin, flushing liquor, free hemoglobin, cell debris) then overflows from container handling and enters in the waste fluid bag.When being full of erythrocyte in the container handling, injecting normal saline and clean.Cell is by the normal saline clean, and leukocyte, platelet, free hemoglobin etc. are diluted repeatedly and discharge, and stop centrifugal treating, and the erythrocyte after the washing is pumped to and has promptly accomplished autohemic recovery in the transfusion bags.Above-mentioned whole process can realize through blood recovery system, in operation, is widely used.
Autoblood reclaims and to have significant superiority in the art, shows: 1. for patient has practiced thrift spending, and the patients that transfuse blood in a large number of the more need of amount of bleeding especially; 2. solved in the art trouble and worry for the patient of special blood group (is the negative patient of Rh like blood group) with blood; 3. significantly reduced the generation of the various infectious diseases of propagating through the allosome blood transfusion, like hepatitis B, AIDS etc.; 4. significantly reduced because of the anaphylactoid generation due to the allosome blood transfusion; 5. practice thrift the blood source, that reduces that blood bank faces uses blood pressure power.
But autoblood reclaims the contraindication that it is also arranged in the art, because of blood recovery system does not possess the function of sterilizing and removing tumor cell, so the blood of open injury and tumour patient can not reclaim, spreads with systemic infection and the tumor that prevents to cause because of septicemia.In addition, erythrocyte number and the function through the normal saline washing all has very macrolesion.How can in art, guarantee to reclaim the safety of blood in the autoblood recovery, and protect erythrocytic quantity of institute's washed blood and function to greatest extent, to reclaim quality to reach best blood, be the continuous problem of exploring of scholars of this area always.
Utility model patent ZL200910210857.5 discloses a kind of safe, reliable and strong disposable use tumor cell filter of clinical practice property, and tumor cell can not be survived in the filtering blood of this cell filter.But this cell filter in use, and filtering blood exists and to be filtered the film safety hidden danger such as fiber contamination and air pollution that come off.
Summary of the invention
In view of this, in order to overcome the deficiency of prior art, this utility model provides in a kind of further filtering blood the filter membrane fiber that comes off, and reduces air pollution nucleated cell depurator to greatest extent.
The nucleated cell depurator that this utility model provides; Said depurator comprise the loam cake that is communicated with blood vessel, be communicated with the lower cover of blood vessel and be fixed on loam cake and lower cover between filter membrane, combine closely through welding between said loam cake and lower cover, said filter membrane is the acetate non-woven fabrics of aperture 7-20 μ m; Saidly enter the center that blood vessel is positioned at loam cake; Go out the center that blood vessel is positioned at lower cover, said nucleated cell depurator is a flat, and said depurator lower end is provided with blood transfusion and uses Murphy tube.
The filter membrane aperture is 20-40 μ m in the Murphy tube, can the fiber filter that comes off in the blood after the acetate non-woven fabrics filters be fallen.
Further, on the said depurator upper and lower cover inwall several crisscross blood guide channels are set all.
Groove in the said blood guiding groove can guide blood scatter and flows through filter membrane, and the filter membrane all directions can both be fully used.
Further, said depurator loam cake is by inside and outside two-layer the composition, and internal layer is offered homodisperse aperture, and the cavity of inside and outside two interlayers communicates with the dispersion apertures of advancing on blood vessel and the internal layer of outer center.
Said depurator loam cake is similar has a bath with the structure of shower head, blood is scatter flow through filter membrane, and the filter membrane all directions can both be fully used.
Further, saidly advance blood vessel and steam vent is set near the position of nucleated cell depurator.
Because this steam vent is away from filter membrane, it is cleaner to be arranged on the steam vent that covers in the purification, is difficult for being polluted by outside air.
Further, saidly advance blood vessel and needle hub is set inserts in the blood reclaiming bag and be connected with the blood reclaiming bag.
Guarantee the sterile working, prevent blood contamination in the operating process.
Further, saidly advance blood vessel the screw socket interface is set, said screw socket interface is connected with the blood reclaiming bag through inserting in blood reclaiming bag with its screw socket progressive joint that is complementary.
In the same assurance sterile working process, blood is not contaminated.
Further, said with advance the blood reclaiming bag that blood vessel is connected and be provided with containing mark, every 12-200cm
2Filter membrane disposable filtering blood volume 200-1200ml is preferably 400-1200ml.
When tumor operation blood reclaims, for the blood flow volume of avoiding purifying surpasses the depurator working range, the special blood reclaiming bag that is complementary with it according to its working range design, and on bag, be carved with scale.
The beneficial effect of this utility model is:
This utility model is the filter membrane fiber that comes off in the filtering blood fully, and reduces the pollution of blood in sterile working's process to greatest extent.With the washing of MAP liquid it being soaked into the back uses; No matter whether contain tumor cell in the filtering blood; This filter all can with all nucleated cell or filter out or destruction; Cause through no longer containing active nucleated cell in the blood of filter, yet to there not being nuclear erythrocyte but not have destruction.Be applicable to that blood reclaims in tumor patient and the non-tumor patient art, the filtration of storehouse blood.
