Embodiment 1

[0028] This embodiment provides the preferred embodiment of plasma lipid filter:

[0029] Such as figure 1 A schematic diagram of the structure of a plasma lipid filter is shown. The plasma lipid filter includes a first housing 10 , a second housing 20 and a casing 40 . The first housing 10 has a convex structure with an opening at the bottom, the second housing 20 has an inverted convex structure and an opening at the top, and the bottom opening of the first housing 10 and the top opening of the second housing 20 join to form an accommodation space , the first housing 10 partially overlaps the side of the second housing 20 . The casing 40 wraps around the side surfaces of the first casing 10 and the second casing 20 to securely connect the first casing 10 and the second casing 20 . The first shell, the second shell and the casing are made of polycarbonate material.

[0030] A filter core 30 and a net plate 50 are disposed in the accommodation space formed by the first hou...

Embodiment 2

[0036] Embodiment two, the flow process of plasma filtration

[0037] In this embodiment, the steps of plasma filtration using a plasma lipid filter are as follows:

[0038] 1) Connect the blood inlet and the exhaust port with the plasma bag pipeline and the air filter exhaust pipe respectively, and connect the bleeding port with the plasma return pipeline;

[0039] 2) Plasma is injected into the filter device from the blood inlet;

[0040] 3) The blood plasma is filtered through the first filter membrane, the second filter membrane, the first filter membrane, the first filter membrane and the third filter membrane arranged in sequence, wherein, the first filter membrane 31 is made of liposome, fibrinogen Affinity adsorption function DELP membrane; the second filter membrane 32 is a 90SP deep filter membrane that absorbs inflammatory factors and free radicals; the third filter membrane 33 is a 0.2 micron membrane that filters out various particulate matter with a pore size gr...

Abstract

The plasma lipid filter comprises a first shell and a second shell, and the first shell is provided with a blood inlet; the second shell and the first shell are connected to form a containing space, a blood outlet is formed in the bottom face, opposite to the first shell, of the second shell, and the bottom face is arranged in an inclined mode; a filter element and a screen plate are arranged in the containing space, and the screen plate is located below the filter element to support the filter element. According to the plasma lipid filter, adhesion of plasma to the bottom face of the filter is reduced, the plasma is filtered more easily, and the possibility that a filter membrane of the filter element is broken is reduced.

Description

technical field [0001] The application relates to the technical field of medical devices, in particular to a plasma lipid filter. Background technique [0002] Hyperlipidemia is increasingly becoming a common disease, which is caused by the increase of low-density lipoprotein levels in human blood. If it is not cleared in time, it can further cause atherosclerosis, coronary heart disease, stroke and heart and brain diseases. Infarction and other cardiovascular and cerebrovascular diseases. Conventional treatment methods for hyperlipidemia include diet control, lifestyle changes, and drug therapy. However, for patients with familial hyperlipidemia and those who are ineffective to the above-mentioned treatments, extracorporeal blood lipid removal methods can be used clinically for treatment. Blood lipid filtration is a common treatment in extracorporeal removal therapy. It mainly separates the patient's plasma and passes through a filter device to filter out relatively large ...
