Description

医用血液透析滤过机 The medical hemodiafiltration machine

技术领域 FIELD

本发明涉及一种医疗设备,尤其是用于清除患者体内外源性和内源性毒物、废物或其它有害物质的医用血液透析滤过机。 The present invention relates to a medical device, in particular for removing patient endogenous and exogenous toxic, hazardous waste or other medical substances hemodiafiltration machine. 背景技术 Background technique

血液透析(HD)和血液滤过(HF)是血液净化领域使用最为广泛的治疗方式。 Hemodialysis (HD) and hemofiltration (HF) is the most widely used field of blood purification treatment. 而两种治疗模式最后都需要血液透析器或血液滤过器来达到清除毒素的目的, 它们在结构上没有本质的差别,都是由大量的空心纤维管组成的,这些空心纤维管是一种具有高通透性的半透膜,血液中的中小分子物质可以自由通过,而血液中的较大分子(如多数蛋白、血浆成分物质、血细胞等)不能通过。 The two treatment modes eventually need dialysis or hemofiltration device to achieve the purpose of removing toxins, they are not essentially different in structure, are by a large number of hollow fiber tubes, which is a hollow fiber tube a semipermeable membrane having a high permeability, small molecular substances in the blood can freely pass, while the larger molecules in the blood (e.g., most proteins, plasma component material, blood cells, etc.) can not pass through. 一般血液滤过器上的半透膜能通过中小分子物质,而血液透析器只能通过小分子物质,故它们清除毒素的范围是不一样的,一般血液滤过治疗时采用血液滤过器, 血液透析时采用血液透析器。 Semi-permeable membrane through hemofilter generally small molecules, but only through the hemodialyzer small molecules, so that they clear the range of toxins are not the same, is generally employed hemofilter hemofiltration treatment, using a hemodialyzer during hemodialysis.

血液透析是利用弥散和超滤原理将患者的血液、透析液同时引入透析器, 在透析膜内外两侧呈反向流动,借助于膜内外两侧的溶质浓度梯度、渗透梯度和水压梯度,通过弥散作用达到两侧浓度平衡,清除人体内新陈代谢废物和多余水分,同时可补充需要的物质,纠正电解质和酸碱平衡紊乱。 Hemodialysis is the use of the principle of diffusion and ultrafiltration of blood of the patient, while the dialysate is introduced into the dialyzer, as a reverse flow in the external sides of the dialysis membrane, by means of the solute concentration gradient across the membrane inside and outside osmotic gradient and pressure gradient, by balancing the dispersion effect a concentration on both sides, to remove the body metabolic wastes and excess water, can be added while the material needs to correct electrolyte and acid-base balance disorders. 血液滤过是利用压力梯度,将血液中有害物质和水分通过滤过器半透膜排出体外,同时补入一定量的置换液入人体血液,纠正电解质和酸碱平衡紊乱。 Hemofiltration is the use of a pressure gradient, harmful substances in the blood and excreted through water filtration device a semipermeable membrane, at the same time make a certain amount of replacement fluid into the blood, correction of electrolyte and acid-base balance disorders. 血液透析一般清除小分子毒素的效果良好,对中分子毒素几乎没有清除作用,且治疗过程中患者耐受性差;而血液滤过中分子毒素清除效果较好,且有利于患者治疗过程中的血压稳定,但小分子清除效果较差。 Hemodialysis remove small molecule toxins generally good results, almost no effect on the clearance molecule toxins, and poor patient tolerance during treatment; and hemofiltration molecule toxins better clearance, and is conducive to patient blood during treatment stable, but the small molecule clearance less effective.

血液透析滤过治疗(HDF)是透析和滤过治疗同时进行的一种方式,它综合了血液透析和血液滤过的优点。 Hemodiafiltration (HDF) is a way to dialysis and filtration treatment simultaneously, it combines the advantages of hemodialysis and hemofiltration. 目前,血液净化领域尚无同时进行血液透析滤过治疗的血液净化设备。 Currently, there is no blood purification field at the same time hemodiafiltration treatment of blood purification equipment. 已有的透析机自动化程度不高,操作比较复杂;而滤过机普遍采用人工配制置换液或买现成的置换液使用,存在操作繁琐、容易污染、价格较高等缺点。 Existing dialysis machine automation degree is not high, the operation is more complex; and filtration machines commonly used artificial preparation of replacement fluid or buy ready-made replacement fluid to use, cumbersome operations, easily contaminated, higher prices and other shortcomings. 具体介绍如下: Detailed below:
