Description
Technical Field
The present invention relates to separation technology, and more particularly to a blood separation device.
Background
The blood provides the functions of transporting substances, immunizing and stopping bleeding in human body, and mainly consists of plasma and blood cells, wherein the plasma comprises plasma proteins, lipoproteins, hormones, enzymes, antibodies and cell metabolites, and the blood cells refer to red blood cells, white blood cells or platelets. Therefore, blood is rich in many components, and the medical use of different components is different.
Generally, when obtaining desired Blood components, centrifugation is generally used to separate the Blood components into a Plasma layer (Blood Plasma), a Buffy Coat layer (Buffy Coat) and a red Blood cell sediment layer due to different specific gravities. Among them, the medical value of the buffy coat has been gradually discovered and paid attention in recent years, and the buffy coat contains high-concentration platelets, lymphocytes, growth factors and a small amount of stem cells, and thus can be regarded as a precious medical resource. However, because the volume occupied by the buffy coat layer is relatively rare relative to the volume occupied by the plasma layer and the erythrocyte sedimentation layer, and only occupies 1 percent of the whole blood volume, the buffy coat layer positioned between the plasma layer and the erythrocyte layer is generally difficult to distinguish in the process of extraction, so that the subsequent separation pipetting procedure has the problems of pollution and inaccuracy. Therefore, how to ensure that the precious buffy coat is not wasted in the separation and pipetting process and improve the recovery rate of cells is still a great need for improvement in the industry.

Detailed Description
To explain the present invention in more detail, the following description will be made of a plurality of preferred embodiments of the present invention with reference to the accompanying drawings.
Referring to fig. 1 to 4, a blood separating apparatus according to a preferred embodiment of the present invention mainly includes a main body 10, a cover 20 and a piston 30, wherein:
the body 10 includes a body 11, an accommodating space 12 disposed inside the body 11 for accommodating external blood to be separated, a first opening 13 disposed at one end of the body 11 and communicating with the accommodating space 12, and a second opening 14 disposed at the other end of the body 11 and communicating with the accommodating space 12. In this embodiment, the main body 10 further includes a combination portion 15 and a limiting portion 16, the combination portion 15 is disposed at one end of the body portion 11 and is adjacent to the first opening 13, and the limiting portion 16 is disposed at the other end of the body portion 11 and is adjacent to the second opening 14.
The cover portion 20 is detachably provided to cover the first opening 13. In detail, the cover 20 is connected to the combining portion 15 for covering the first opening 13, wherein the combining portion 15 has an external thread 151, and the cover 20 has an internal thread 21 engaged with the external thread 151 of the combining portion 15, so that the cover 20 and the body 11 are screwed together. In the present embodiment, the number of the lid portions is two, and the difference between the two lid portions 20, 20a is: one of the cover portions 20 is used to close the first opening 13 (as shown in fig. 1 and 2), and the other cover portion 20a has a flow passage 22a, one end of which is communicated with the accommodating space 12, and the other end of which is communicated with the outside (as shown in fig. 3 and 4).
The piston 30 is slidably disposed in the accommodating space 12 and tightly abuts against the body 11 with the peripheral end surface thereof, and is disposed between the first opening 13 and the second opening 14. In the present embodiment, the position-limiting portion 16 is used for limiting the piston 30 to prevent the piston 30 from separating from the body 10 from the second opening 14. Wherein, the position-limiting part 16 is formed on the inner wall of the body part 11 in the radial direction. In addition, the piston 30 is further connected to a push rod 31, and the other end of the push rod 31 passes through the second opening 14 and extends out of the body 11.
By means of the above components and the flow chart of fig. 5, the operation steps of the present invention are as follows:
step A: taking the piston 30 and putting it into the body 10, and making one side of the piston 30 abut against the limiting part 16;
and B: placing the blood sample 40 into the accommodating space 12;
and C: covering the cap 20 on the first opening 13, placing the completely processed body 10 in a centrifuge tube 50, centrifuging, and allowing the centrifuged and layered blood sample 40 to present a plasma layer 41, a buffy coat layer 42 and a red blood cell sediment layer 43 from top to bottom;
step D: after centrifugation, taking out the body 10 from the centrifuge tube;
step E: replacing the lid portion 20 with another lid portion 20a having a flow passage 22 a;
step F: the push rod 31 is connected to one side of the piston 30, so that the piston 30 can be pushed by the push rod 31 to slide in the accommodating space 12 in the body 10, thereby driving the centrifugally layered blood sample 40 to move in the body 10 and be sequentially discharged from the flow channel 22a of the cover 20a, and accordingly, the user can accurately extract the desired buffy coat 42.
Accordingly, the blood separation device provided by the utility model can efficiently perform centrifugal stratification of blood and extraction of specific blood stratification, and has a simple structure and easy operation. In other embodiments, the body 10 may be directly placed in a centrifuge for centrifugation in step C.
