Problems solved by technology

If a system is established that can collect a small amount of blood using a blood collection tool that can be used at home to prepare specimens for biochemical tests, they can be quickly delivered to blood testing institutions and test results can be obtained in a short time, not limited to home medical treatment, Even in areas without medical institutions, developing countries, etc., it can be a very useful system, and it can also meet the current increasing global health care requirements, but the current situation is that a practically useful system has not yet been adopted. to develop

Embodiment 1

[0057] One embodiment of the present invention consists of at least the core 2 ( figure 1 ) and the outer shell 5 ( figure 2 ) Plasma or serum (hereinafter referred to simply as "plasma") composed of separation device 1. The housing 5 includes a housing cover 51 and a housing base 52 .

[0058]

[0059] as in figure 1 As in , the structure of the core part 2 of the plasma separation device 1 of the present invention is roughly composed of the blood separation part 3 and the plasma recovery part 4 .

[0060] First, the blood separation unit 3 includes at least a blood separation member 31 and a blood separation unit base 32 for placing (supporting) the blood separation member 31 . Moreover, the plasma recovery unit 4 includes at least two plasma recovery members 41 (a, b), an adhesive member 43 that seals the ends 42 of these plasma recovery members 41 in a liquid-tight manner, and two blood plasma Plasma recovery region 44 surrounded by recovery member 41 and adhesive...

Embodiment 2

[0221] One of the other embodiments of the present invention is an improved type of Embodiment 1, and is a blood plasma separation device 10 ( Figure 7 ~ Figure 10 ).

[0222] The basic structure is the same as that of the first embodiment, and the technical meaning of each part is the same as that described in the first embodiment as long as the names are the same.

Abstract

The invention provides a plasma (or serum) separation device, by which plasma components, even in a minute amount, can be surely, economically and quickly separated from blood anywhere without using acentrifuge, a suction / pressurization pump, etc., and a plasma (or serum) separation method. A plasma separation device comprising a blood separation unit provided with a blood separation member and aplasma collection unit provided with a plasma collection member, wherein: the blood separation member is placed on a hydrophobic pedestal and comprises a blood receiving area and a plasma separationarea connected to the plasma collection unit; and the cross-sectional area of the plasma separation area is reduced toward the plasma collection unit. The term "plasma" as used herein means "plasma orserum".

Description

technical field [0001] The present invention relates to a device and method for separating liquid components from body fluid or blood, in particular to a device and method for separating plasma (or serum) components from blood. More specifically, the present invention relates to a plasma that can separate plasma (or serum) easily and inexpensively without the need for a centrifugal separator, a suction pump, etc. (or serum) separation device and plasma (or serum) separation method. Background technique [0002] Various clinical states of patients can be determined based on the presence or absence of substances dissolved in body fluids, especially blood, and / or their concentration values. Therefore, medical diagnosis based on blood tests is routinely performed. [0003] Blood samples, especially plasma or serum, can be analyzed after collection to obtain medically useful information such as chemical composition, properties, hematology or coagulation, for example, mineral con...
