Embodiment 1

[0024] see Figure 1-3 , a centrifugal separation device for serum extraction, including a fixed seat 2, a fixed shell 3, a connecting pipe 6 and a rotating seat 10. The four corners of the lower surface of the fixing seat 2 are fixed with rubber support feet 1. The setting of the rubber support feet 1 reduces the shock during the operation of the device, thereby making the device run stably and avoiding poor separation quality caused by blood shock. A hollow fixed shell 3 is fixed on the upper surface of the fixed base 2 , and an outer cover 4 is hinged on the top of the fixed shell 3 . The inside of the fixed shell 3 is provided with a truncated circular rotating base 10 for rotation, and the bottom of the rotating base 10 is coaxially fixedly connected with a driven wheel 11 . The side of driven wheel 11 is fixedly installed with motor 12 inside holder 2, and the output shaft coaxial of motor 12 is fixedly connected with driving wheel 13, and driving wheel 13 is connected ...

Embodiment 2

[0028] see Figure 4 , On the basis of Embodiment 1, a positioning sleeve 18 is slidably nested on the connecting pipe 6, and the positioning sleeve 18 is a coaxial cylindrical structure made of rubber. The setting of the positioning sleeve 18 facilitates the fixing of the connecting pipe 6 and prevents the connecting pipe 6 from shaking. Both ends of the connecting pipe 6 are provided with scale lines 19, which are convenient for quantitatively controlling the insertion amount of the connecting pipe 6, avoiding incomplete separation and improving the separation quality.

Abstract

The invention relates to the technical field of blood separation, and specifically discloses a centrifugal separation device for serum extraction, which includes a fixed seat, a fixed shell, a connecting pipe and a rotating seat. The upper surface of the fixed seat is fixed with a hollow fixed shell, and the inside of the fixed shell is A frustum-shaped rotating seat is provided for rotation, the bottom of the rotating seat is coaxially fixedly connected with a driven wheel, the side of the driven wheel is fixedly installed with a motor inside the fixed seat, and the output shaft of the motor is coaxially fixedly connected with a driving wheel, and the driving wheel and the The driven wheel is connected by a belt. The inside of the rotating seat is evenly provided with a blood collection tube placement groove and a serum tube placement groove. The serum tube placement groove is outside the blood collection tube placement groove. Perforations corresponding to the serum tube placement groove and the blood collection tube placement groove are provided. The invention has the advantages of simple structure, convenient operation, high separation efficiency, good quality and convenient implementation and popularization.

Description

technical field [0001] The invention relates to the technical field of blood separation, in particular to a centrifugal separation device for serum extraction. Background technique [0002] Serum separation gel is used as the isolation medium in blood collection tubes for serum biochemical or plasma biochemical tests. It can completely separate serum (or plasma) from red blood cells to obtain high-quality serum (or plasma), effectively ensuring the accuracy of blood tests. After blood collection, blood can be centrifuged to separate serum (or plasma) and red blood cells after coagulation or anticoagulation. Since the specific gravity of serum separating gel is between that of serum (or plasma) and red blood cells, it moves and reverses between the two components during centrifugation. After the centrifugation stops, the serum (or plasma) is separated from the red blood cells, which acts as a separation barrier. [0003] Chinese patent (notification number: CN 208574658 U, ...
