[0007] Preferably, a connecting tube is fixedly provided at the lower end of the first tube body, the lower end of the connecting tube is provided with the second cover body, and a disconnecting portion is provided on the connecting tube between the second cover body and the lower end of the first tube body, and the disconnecting portion can be disconnected under the action of external force.

[0008] Compared with the prior art, the utility model has achieved the following technical effects:

[0009] The blood sample holding device provided by the utility model adopts a first tube body for holding an FTA card for molecular detection of the blood sample. When collecting the blood sample, only about 100 ml of the blood sample needs to be dropped on the FTA card located in the first tube body, and there is no need to use an anticoagulant tube to hold the blood sample. In addition, for the detection of multiple pathogens, only a 2 mm circle needs to be punched on the dried FTA card, which can be used for the detection of a pathogen nucleic acid after processing. Therefore, it is suitable for the simultaneous detection of multiple pathogens. With the existing blood collection method, it is impossible to collect only 100 ml of blood into an anticoagulant tube for the detection of multiple pathogens, because there will be loss and coagulation caused by non-compliant transportation temperature; the amount of blood sample in the second tube body only needs to maintain the required amount, therefore, the overall amount of blood required for comprehensive molecular detection and antibody detection is reduced; and the required blood sample can be placed in the corresponding first tube body and second tube body in a single blood collection, which reduces the number of collections compared to two blood collection actions; after the blood sample is dripped into the first tube body, the second cover on the second tube body is opened to add the blood sample to the second tube body, and after the collection is completed, the second cover on the first tube body is closed on the second tube body. Compared with the existing preparation of two different tubes, the operation is simpler and more convenient, reducing the workload of the sampling personnel.

[0018] This embodiment provides a blood sample holding device 100, such as Figure 1 As shown, it includes a first tube body 2 and a second tube body 5; the first tube body 2 has a first accommodating cavity and a first opening connected to the first accommodating cavity, and the first opening is closed with a detachable first cover body 1; the second tube body 5 has a second accommodating cavity and a second opening connected to the second accommodating cavity; the lower end of the first tube body 2 is provided with a second cover body 4 capable of closing the second opening; an FTA card 6 for molecular detection of blood samples is placed in the first accommodating cavity; the blood sample contained in the second accommodating cavity is used for antibody detection.

[0019] By adopting the first tube body 2 containing the FTA card 6 for molecular detection of blood samples, when collecting blood samples, it is only necessary to drop about 100 ml of blood sample on the FTA card 6 located in the first tube body 2, and there is no need to use the existing anticoagulant tube to hold the blood sample. For the detection of multiple pathogens, it is only necessary to punch a 2 mm circle on the dried FTA card 6, and after processing, it can be used for the detection of a pathogen nucleic acid. Therefore, it is suitable for the simultaneous detection of multiple pathogens. However, with the existing blood collection method, it is impossible to collect only 100 ml of blood into an anticoagulant tube for the blood detection of multiple pathogens, because there will be loss and coagulation caused by non-compliant transportation temperature; the amount of blood sample in the second tube body 5 only needs to maintain the required amount, therefore, the overall amount of blood required for comprehensive molecular detection and antibody detection is reduced; and the required blood sample can be placed in the corresponding first tube body 2 and second tube body 5 in a single blood collection, which reduces the number of collections compared to two blood collection actions; after the blood sample is dripped into the first tube body 2, the second cover body 4 covering the second tube body 5 is opened to add the blood sample to the second tube body 5, and after the collection is completed, the second cover body 4 on the first tube body 2 is covered on the second tube body 5. Compared with the existing preparation of two different tubes, the operation is simpler and more convenient, reducing the workload of the sampling personnel.

[0020] In order to ensure the sealing of the blood samples in the first tube 2 and the second tube 5 when they are sent to the laboratory:

[0021] Specifically, the first tube body 2 and the second tube body 5 can be separated by removing the second cover body 4 at the lower end of the first tube body 2 from the second tube body 5 when separation is required, and covering the second tube body 5 with a new cover body; in order to better achieve the effect of isolating and containing the blood samples in the first tube body 2 and the second tube body 5, the following settings can also be used to achieve the separation of the first tube body 2 and the second tube body 5:

After the blood sample for molecular detection and antibody detection is collected and sent to the laboratory, the disconnection portion 31 can be disconnected by applying an external force such as manually bending, that is, the first tube body 2 and the second tube body 5 are separated, so that the first tube body 2 and the second tube body 5 are respectively sent to the molecular chamber and the serum chamber for different detections.

[0023] Specifically, the connecting pipe 3 is not connected to the first pipe body 2 and the second pipe body 5 .

[0024] Specifically, the disconnection portion 31 on the connecting pipe 3 can be any existing structure that can achieve disconnection at the disconnection point, including but not limited to, for example, a disconnection mark groove set on the connecting pipe 3, so that the operator can directly break it by hand to separate it.

[0025] Among them, regarding the overall structure formed by the first tube body 2, the connecting tube 3 and the second tube body 5:

[0026] Specifically, the first tube body 2, the connecting tube 3 and the second tube body 5 form a centrifuge tube, the size of which is equivalent to 1.5 5 ml centrifuge tubes, that is, the second tube body 5 is a standard 5 ml centrifuge tube, and the first tube body 2 and the connecting tube 3 form a 2.5 ml centrifuge tube.

[0027] Among them, regarding the placement and removal of the FTA card 6 in the first tube 2:

[0028] Specifically, the FTA card 6 is an existing component, which is a special filter paper; the FTA card 6 is embedded in the first tube body 2.

[0029] Specifically, when collecting blood, first drop 100 ml of blood sample on the FTA card 6, do not take it out, cover it with the first cover body 1, and let it dry naturally.

[0030] Principle description: 3-5 ml of blood sample is collected each time, and only 100 ml of blood sample is dripped on the FTA card 6 to complete the collection of molecular detection samples. The remaining blood sample is placed in the second tube 5 for serological detection.
