DETAILED DESCRIPTION

[0027] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0028] See also Figure 1-Figure 5 A novel intelligent blood collection bag comprises a blood collection bag body 1, wherein the blood collection bag body 1 has a blood collection bag 2. Figure 1In the figure, the blood collection bag body 1 is a quadruple bag in the prior art, and correspondingly, it can also be a triple bag or a quintuple bag, and the blood collection bag 2 is the first bag in the multi-bag, and the blood first enters the bag after leaving the human body;

[0029] The top of the blood collection bag 2 is connected with a connecting tube 3, and the end of the connecting tube 3 is connected with a first branch tube 5 and a second branch tube 7 through a three-way connector 4, the end of the first branch tube 5 is connected with a blood collection needle 6, and the end of the second branch tube 7 is connected with a bypass sample bag 8;

[0030] The top of the bypass sample bag 8 is connected to a bypass tube 9, and the end of the bypass tube 9 is connected to four branch tubes 11 through a five-way joint 10, the ends of the four branch tubes 11 are all connected to a connecting portion 12, and the end of the connecting portion 12 is connected to an injection needle 13, a sample tube 14 is arranged below the injection needle 13, and a connection cover 15 for the injection needle 13 to penetrate is arranged on the top of the sample tube 14;

[0031] The outside of the blood collection bag body 1, the outside of the bypass sample bag 8 and the outside of the sample tube 14 are all provided with a pasting area 16, and the pasting area 16 is used to paste the blood donation barcode;

[0032] The branch pipe 11, the bypass pipe 9, the first branch pipe 5, the second branch pipe 7 and the connecting pipe 3 are all provided with a liquid stop clamp 17;

[0033] In this embodiment, the outside of the blood collection bag body 1, the outside of the bypass sample bag 8 and the outside of the sample tube 14 are all provided with a pasting area 16, so that the pasting area 16 can be used to paste the blood donation barcode, thereby avoiding the problem of incorrect pasting and missing pasting of the blood donation barcode, and having the advantage of being faster and more convenient when used;

[0034] Specifically, during the blood drawing operation, the blood of the blood donor is collected using the blood collection needle 6. At this time, the connecting tube 3, the bypass tube 9 and the liquid-stopping clamps 17 on the branch tube 11 are closed, while the liquid-stopping clamps 17 on the first branch tube 5 and the second branch tube 7 are opened, so that the blood can enter the bypass sample bag 8 through the first branch tube 5 and the second branch tube 7. The volume of the bypass sample bag 8 is about 30-40 ml. After a certain volume of blood is infused into the bypass sample bag 8, the liquid-stopping clamp 17 on the second branch tube 7 is closed, and at the same time, the liquid-stopping clamp 17 on the connecting tube 3 is opened, so as to stop the infusion of the bypass sample bag 8 and instead infuse blood into the blood collection bag 2 through the connecting tube 3. After a certain volume of blood is infused, the liquid-stopping clamps 17 on the first branch tube 5 and the connecting tube 3 are closed and the blood collection needle 6 is pulled out.

[0035] The purpose of this operation is to first use the bypass sample bag 8 to infuse blood, so that part of the skin tissue and even dust impurities brought into the blood when the skin is punctured can enter the bypass sample bag 8 along with the blood, and then infuse blood into the blood collection bag 2 to further ensure that the blood inside the blood collection bag 2 is relatively clean, thereby facilitating subsequent processing and use;

[0036] In addition, by arranging four sample tubes 14 in the bypass sample bag 8, the four sample tubes 14 are respectively an enzyme-immune tube, a nucleic acid tube, a biochemical tube, and a sample tube, and each sample tube 14 is provided with a pasting area 16 for pasting a blood donation barcode, so that the problem of wrong blood sample tubes and missed samples can be avoided, and for the initial screening of reactive specimens, there is no need to review the blood bag catheter specimens; at the same time, the dedicated sample retention tube can avoid the later work of centrifugation and heat sealing of the blood bag catheter, and fully meets the sample quality requirements of the later enzyme-immune and nucleic acid tests; and the integrated blood sample tube avoids the risk of injuring staff using a sample collection needle.

[0037] Furthermore, an anti-dropping component 18 is disposed outside the connection cover 15 , and the anti-dropping component 18 is used to assist in fixing the position of the connection part 12 after the injection needle 13 penetrates the connection tube 3 and extends into the interior of the sample tube 14 .

[0038] Furthermore, the anti-falling assembly 18 includes a collar 181 arranged outside the connection cover 15 , and a second sleeve 183 is fixed to the outer side wall of the collar 181 , and a plurality of clamping blocks 184 are penetrated through the middle of the second sleeve 183 .

[0039] Furthermore, the outer wall of the collar 181 is connected to the first sleeve 182 located outside the second sleeve 183 through threads, and the inner wall of the first sleeve 182 is fixed with an annular trapezoidal block 186; the end of the clamping block 184 facing the annular trapezoidal block 186 is provided with a triangular block 185 adapted to the annular trapezoidal block 186;

[0040] Specifically, when the injection needle 13 penetrates the connection cover 15 and is inserted into the designated position inside the sample tube 14, the first sleeve 182 is rotated so that the first sleeve 182 can rise or fall under the action of the thread. When the first sleeve 182 is rotated and raised, the annular trapezoidal block 186 rises accordingly. Figure 4It can be seen that the inclined surface on the annular trapezoidal block 186 cooperates with the inclined surface on the triangular block 185, so that when the annular trapezoidal block 186 rises, the triangular block 185 will move the clamping block 184 toward the direction of the connecting part 12, and then use the clamping block 184 to clamp the connecting part 12. In order to improve the clamping effect, the clamping block 184 includes two parts, one part is a fixed part fixedly connected to the triangular block 185, and the other part is an anti-slip part for clamping the connecting part 12, and then the anti-slip part made of anti-slip material (such as rubber, etc.) is used to improve the clamping effect, ensuring that after the injection needle 13 is inserted into the interior of the sample tube 14, the two can be effectively stabilized.

[0041] Furthermore, an anti-slip cotton 19 is provided on the inner side wall of the collar 181, and both upper and lower ends of the anti-slip cotton 19 are provided with chamfers;

[0042] In the prior art, the outside of the connecting cover 15 on the sample tube 14 is provided with anti-slip textures, and by further providing anti-slip cotton 19 in the ring 181, the ring 181 and the connecting cover 15 can be detachably connected, which facilitates the recycling of the entire anti-fall-off component 18.

[0043] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
