Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in figure 1, the venous blood collection and separation container comprises a pipe body 1, a breathable bacteria-blocking rubber plug 2 and a rubber cap 3, wherein the pipe body 1 is transparent and comprises a cylindrical cavity 11, a conical cavity 12 and a small rubber plug cavity 13 which are sequentially and integrally connected, and the cross section of the cylindrical cavity 11 is annular. A small rubber plug 14 is arranged in the small rubber plug cavity 13 and used for plugging the lower port of the pipe body 1. The air-permeable and bacteria-resistant rubber plug 2 is arranged in the upper opening of the cylindrical cavity 11 and is in interference fit with the cylindrical cavity 11, namely, is in tight joint, so that the joint of the air-permeable and bacteria-resistant rubber plug and the cylindrical cavity is airtight. Ventilative fungus plug 2 that hinders includes plug main part 21 and ventilative fungus membrane 22 that hinders, sets up ventilative round hole 23 that link up from top to bottom in the plug main part 21, and ventilative fungus membrane 22 that hinders sets up in ventilative round hole 23 and leans on the lower part position for block the passageway of ventilative round hole 23. The breathable bacteria-resistant film 22 is formed by melting the breathable bacteria-resistant film on a PET sheet in a hot melting mode and then integrally forming the breathable bacteria-resistant film by using medical silica gel in a rubber coating mode. As shown in fig. 3, the rubber cap 3 includes a top cover 31 and a matching cover I32 which are integrally connected, the top cover 31 and the matching cover I32 are both concentric cylinders, and the diameter of the matching cover I32 is smaller than that of the top cover 31, and is used for interference fit with the upper opening of the cylindrical cavity 11, so that the joint between the top cover and the matching cover I will not leak gas.
Rubber cap 3 still covers II33 including the cooperation, cooperation lid II33 and cooperation lid I32 body coupling for with breathe freely hinder ventilative round hole 23 on the fungus plug 2 and be connected, conveniently breathe freely hinder fungus plug 2 and rubber cap 3 formation assembly, the body 1 of conveniently impressing simultaneously in the vacuum chamber.
As shown in fig. 2, the surface of the rubber plug body 21 is provided with a plurality of annular protruding strips 24, so as to ensure that the rubber plug body 21 and the inner side of the cylindrical cavity 11 do not leak air.
As shown in fig. 1, an annular baffle 15 is disposed at one end of the small rubber plug cavity 13 for limiting the small rubber plug 14.
The small rubber plug 14 is packaged in the small rubber plug cavity 13 in a hot melting mode, the front of the small rubber plug is limited by the annular baffle plate 15, and the rear of the small rubber plug is limited in a hot melting mode, so that the small rubber plug 14 is fixed in the small rubber plug cavity 13. Specifically, the material of the small rubber plug 14 is polyisoprene.
The working principle of the venous blood collection and separation container is as follows: the application method comprises blood sampling stage and blood sampling stage after centrifugation. In the blood sampling stage, the matching cover I32 is plugged into the cylindrical cavity 11, negative pressure is formed in the tube body 1, and blood is directly collected into the tube body 1 from the lower end through the matching use of the small rubber plug 14 and the venous blood sampling needle.
After blood collection is finished, the rubber cap 3 is taken down, so that the pressure difference between the inside and the outside of the tube body 1 is kept consistent. Then put into centrifuge with body 1 and carry out high-speed centrifugation for the first time, after high-speed centrifugation for the first time, blood forms three layering in the heparin tube: from bottom to top (from the conical cavity 12 to the cylindrical cavity 11) are a red blood cell layer, a platelet layer and a serum layer in sequence. The deep-color red blood cell layer is extracted by puncturing the small rubber plug 14 at the lower end of the tube body 1, and in the extraction process, the breathable bacterium-blocking rubber plug 2 can achieve the effect of blocking bacteria in the air and can also keep the balance of the air pressure inside and outside the blood collection tube body. Then, the tube body 1 is shaken up and subjected to secondary high-speed centrifugation. After the second high speed centrifugation, the blood formed three layers within the blood collection tube: from bottom to top, a small amount of red blood cell layer, platelet layer and serum layer are arranged in sequence. The platelet rich concentrates in the conical cavity 12 of the lower end of the tube body of the hemostix, punctures from the small rubber plug of the lower end of the tube body, the needle head passes through the erythrocyte liquid surface layer and is slightly higher than the erythrocyte liquid surface by 1-3 mm, the platelet rich is extracted, the air-permeable and bacterium-resistant rubber plug 2 can also achieve the function of blocking bacteria in the air in the extraction process, and the balance of the air pressure in the tube body 1 can be kept. After the extraction is completed, the remaining blood sample portion in the tube 1 is discarded. Compared with the prior art, the operation does not need to open the tube body 1 from the upper part, thereby preventing the secondary pollution of air to blood samples, and moreover, the separation container extracts the needed rich platelets from the lower part, thereby being more convenient to operate.
The embodiments of the present invention have been described in detail with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes that can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art can be made within the scope of the claims of the present invention.
