Embodiment Construction

[0046] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0047] Such as figure 1 As shown, the principle diagram of the existing plasma replacement mode, wherein: the peristaltic pump 103 draws blood from the human artery, monitors the blood collection pressure in real time through the blood collection pressure monitoring port 101, and the anticoagulant pump 102 pumps anticoagulant to prevent blood coagulation, and the blood passes through After 103, it enters the arterial jug 104 and monitors the arterial pressure. After passing through the arterial ju...

Abstract

The invention provides a plasma exchange and photochemical virus inactivation device and application equipment thereof. The device comprises an inducer mixing unit, a photochemical virus inactivationunit and an inducer removing unit, wherein the inducer mixing unit is used for mixing viruliferous plasma filtered out by adopting a plasma exchange manner and an inducer and conveying mixed plasma containing the inducer into the photochemical virus inactivation unit; the photochemical virus inactivation unit is used for irradiating the plasma containing the inducer to complete virus inactivationand conveying inactivated plasma into the inducer removing unit; the inducer removing unit is used for filtering out the inducer remaining in the inactivated plasma, wherein plasma with the inducer removed is used for fluid infusion. In the device, a membrane type plasma separation method and a photochemical virus inactivation method are combined for the first time, so that plasma virus inactivation is performed uninterruptedly in an extracorporeal circulation process of blood.

Description

technical field [0001] The invention relates to blood purification equipment in the technical field of medical devices, in particular to a plasma exchange (PE)-loaded photochemical virus inactivation device and its application equipment. Background technique [0002] Blood purification is to lead the patient's blood out of the body, remove certain pathogenic substances, and purify the blood to achieve the purpose of treating diseases. Plasma exchange PE is a mode of blood purification. It takes the patient's blood out of the body through the blood line, separates the patient's plasma from the whole blood through membrane plasma separation and discards it, and then replenishes the same amount of fresh frozen plasma. Or human serum albumin and other rehydration fluids, so that various metabolic toxins and pathogenic factors in the patient's body can be removed, so as to achieve the purpose of treatment. Plasma exchange PE can not only remove small and medium-sized metabolic t...
