Description
Technical field
This utility model relates to a kind of blood plasma absorption medical apparatus and instruments, relates in particular to a kind of disposable use bilirubin blood plasma adsorption column.
Background technology
In recent years, develop rapidly and popularize in China take the blood purification therapy of extracorporeal circulation as the basis.Wherein, because severe liver diseases patient enormous amount, and the outstanding curative effect of blood plasma adsorbing therapy aspect the heavy hepatopath's symptom of alleviation, the demand of disposable use bilirubin blood plasma adsorption column constantly increases.Make visible component and the separating plasma of blood by extracorporeal circulation, blood plasma is introduced disposable use bilirubin blood plasma adsorption column and is carried out plasma perfusion treatment after will separating, utilize super porous anion resin in the adsorption column can optionally remove bilirubin in the blood plasma, reach the purpose that purifies the blood.
Disposable use bilirubin blood plasma adsorption column is in the blood purification process, be connected in the outer blood circulation loop of lead body, blood is through visible component and the separating plasma of blood plasma separator with blood, with the bilirubin adsorption in the blood plasma, the blood plasma after the absorption converges with the blood effective ingredient that separates before this and enters body-internal-circulation again plasma flow when disposable use bilirubin blood plasma adsorption column.Disposable use bilirubin blood plasma adsorption column is as aseptic medical equipment, enforcement along with " aseptic medical equipment quality of production management regulation ", medicine prison department of country will be more strict to the supervision of Related product, so the sterilization of disposable use bilirubin blood plasma adsorption column, sealed type storage, transportation after particularly sterilizing are extremely important.In the process of transportation, if disposable use bilirubin blood plasma adsorption column is poorly sealed, can cause air to enter the resin anion (R.A.) that pollutes filling in the disposable use bilirubin blood plasma adsorption column, gnotobasis is destroyed, cause and to be used for clinical trial, or because of the not carefully clinically misuse of clinical preoperation inspection, and cause most probably malpractice, bring the risk for the treatment of to the patient.
At present, common disposable use bilirubin blood plasma adsorption column all is comprised of middle cylinder, filter screen, end cap, locking nut, block, rubber cushion and resin anion (R.A.) adsorbent etc., in assembling, filter screen is contained in the middle cylinder, end cap seals middle cylinder, fill a packing ring between end cap and the middle cylinder, by locking nut locking, the blood mouth of end cap central authorities is by the rubber cushion press seal in block and the block between end cap and the middle cylinder.Filter screen generally is to be welded by filter membrane and an annular brace sheet, in clinical practice, in case the adsorption column internal pressure is excessive, owing to do not support in the middle of the filter screen, cause easily filter screen to break, cause the absorption in the adsorption column to enter the blood circulation loop, in a single day the adsorbent of seepage enters in the patient body, will cause immeasurable consequence.Entire terminal cover (containing gland) is in case after tightening sealing, when high pressure steam sterilization, because the effect of temperature and pressure causes distortion easily, also can't seal fully when again tightening after the sterilization simultaneously.Also the someone attempts eddy current or ultra-sonic welded are carried out in needs sealing place, exists equally the very difficult assurance in position of vortex induction circle and bonding wire concentric, and circumference temp is difficult to consistent, and welding effect is difficult to assurance, the many problems of waste product behind the welding fabrication.Although and employing ultra-sonic welded end cap (containing gland) good sealing effect causes cap sealed place pressure excessive deformation easily when high pressure steam sterilization, poorly sealed real problem after the sterilization.
