Description

Technical Field

[0001] The utility model belongs to the technical field of serum separation, and particularly relates to an animal serum separation device. Background Art

[0002] Animal serum refers to the light yellow transparent liquid separated after blood coagulation, removing fibrinogen and certain coagulation factors in the plasma, or the plasma from which fibrinogen has been removed. Its main functions are to provide basic nutrients, hormones and various growth factors, binding proteins, promote contact and growth factors to protect cells from mechanical damage when adhering to the wall, and play certain protective roles for the cells in culture. The most direct existing method for obtaining animal serum is to let the collected animal blood stand still, and after the serum is layered with other substances, the serum is obtained by the method of liquid separation. However, although the above method can finally obtain the serum, in the process of liquid separation, multiple tube pouring operations are required (that is, the serum needs to be transferred between different containers multiple times), which is very inconvenient to operate, thus significantly increasing the workload of the staff. Therefore, there is an urgent need to design an animal serum separation device that does not require multiple tube pouring operations. Content of the Utility Model

[0003] In view of the problems existing in the above-mentioned prior art, an animal serum separation device is disclosed in the utility model, and the following technical solutions are specifically disclosed:

[0004] An animal serum separation device includes a negative pressure liquid separation test tube and a serum storage test tube. A liquid discharge tube is arranged at the bottom end of the negative pressure liquid separation test tube. A plurality of serum discharge tubes are sequentially communicated from top to bottom on the side surface of the negative pressure liquid separation test tube. The serum storage test tube is located on one side of the negative pressure liquid separation test tube. A serum suction tube is arranged at the bottom end of the serum storage test tube. Valves are arranged on the liquid discharge tube, the serum discharge tubes and the serum suction tube. A delivery hose is detachably connected between the serum suction tube and one of the serum discharge tubes. A fixing seat is arranged at the top end of the serum storage test tube. A rubber piston is installed in the serum storage test tube. The top end of the rubber piston is fixedly connected with a threaded rod. The top end of the threaded rod penetrates through the fixing seat and is fixedly connected with a turning head. The threaded rod is threadedly connected with the fixing seat.

[0005] Further, a sealing cover is installed at the top end of the negative pressure liquid separation test tube, and a rubber membrane is arranged in the middle of the sealing cover.

[0006] Further, joint sleeves with internal threads are fixedly connected to both ends of the delivery hose. External threads are arranged on the serum discharge tubes and the serum suction tube. The joint sleeves at both ends of the delivery hose are threadedly connected with the serum discharge tube and the serum suction tube respectively.

[0007] Further, the delivery hose is a PVC pipe.

A serum suction tube 5 is provided at the bottom end of the serum storage test tube 2. A valve is provided on the serum suction tube 5. A transfer hose 6 is detachably connected between the serum suction tube 5 and one of the serum discharge tubes 4. A fixing seat 7 is provided at the top end of the serum storage test tube 2. A rubber piston 8 is installed in the serum storage test tube 2. The top end of the rubber piston 8 is fixedly connected to a threaded rod 9. The top end of the threaded rod 9 penetrates through the fixing seat 7 and is fixedly connected to a turning head 10. The threaded rod 9 is threadedly connected to the fixing seat 7.

[0017] In this embodiment, a sealing cover 11 is installed at the top end of the negative pressure liquid separation test tube 1 to ensure the sealing performance of the negative pressure liquid separation test tube 1. A rubber membrane is provided in the middle of the sealing cover 11. When collecting blood from an animal, one end of the blood collection tube is generally connected to a blood collection needle, and the other end is connected to a bleeding needle. The blood collection needle is inserted into the animal's vein, and the bleeding needle penetrates through the rubber membrane and is inserted into the negative pressure liquid separation test tube 1, so as to collect the animal's blood by using negative pressure.

[0018] In this embodiment, joint sleeves 12 with internal threads are fixedly connected to both ends of the transfer hose 6. External threads are provided on both the serum discharge tube 4 and the serum suction tube 5. The joint sleeves 12 at both ends of the transfer hose 6 are threadedly connected to the serum discharge tube 4 and the serum suction tube 5 respectively. The threaded connection between the joint sleeve 12 and the serum discharge tube 4 and between the joint sleeve 12 and the serum suction tube 5 enables it to be easily assembled and disassembled, making it more flexible and convenient to use.

[0019] In this embodiment, the transfer hose 6 is a PVC tube, and both the negative pressure liquid separation test tube 1 and the serum storage test tube 2 are made of transparent glass.

[0020] In this embodiment, the bottom walls of both the negative pressure liquid separation test tube 1 and the serum storage test tube 2 are circular bottom walls that are lower in the middle and higher around. The liquid discharge tube 3 communicates with the lowest point of the bottom wall of the negative pressure liquid separation test tube 1. The serum suction tube 5 communicates with the lowest point of the bottom wall of the serum storage test tube 2. A circular protrusion adapted to the bottom wall of the serum suction tube 5 is provided at the bottom of the rubber piston 8, so that the bottom of the rubber piston 8 can be completely attached to the bottom wall of the serum suction tube 5, thereby ensuring that there is no extra air in the serum suction tube 5 before sucking the serum.

[0021] In this embodiment, it further includes a test tube support. The test tube support includes a support plate 13. A circular through hole is provided at the center of the support plate 13. A plurality of legs 14 are connected to the bottom surface of the support plate 13 around the circular through hole. A support ring 15 is fixedly connected to the side wall of the negative pressure separation test tube 1. The diameter of the circular through hole is larger than the diameter of the negative pressure separation test tube 1 and smaller than the outer diameter of the support ring 15. The negative pressure separation test tube 1 is erected on the test tube support through the support ring 15. The setting of the test tube support can facilitate the vertical static operation of the negative pressure separation test tube 1.

[0022] In this embodiment, anti-slip threads are provided on the side wall of the screwing head 10, which can facilitate the staff to rotate the screwing head 10.

[0023] The working principle of the present utility model is as follows:

[0024] First, the bleeding needle of the blood collection tube penetrates the rubber membrane and pierces into the negative pressure separation test tube 1 to collect the blood of the animal. After the collection is completed, the negative pressure separation test tube 1 is placed on the test tube support for static settlement. After the serum is separated from other substances, the serum discharge tube 4 at the corresponding height is connected to the serum suction tube 5 through the conveying hose 6. When selecting the serum discharge tube 4, the serum discharge tube 4 with a height higher than the bottom layer substance in the negative pressure separation test tube 1 should be selected to avoid inhaling other substances other than serum. After connecting the conveying hose 6, the valve on the serum discharge tube 4 and the valve on the serum suction tube 5 are opened to connect the negative pressure separation test tube 1 with the serum storage test tube 2. And to ensure the smooth inhalation of serum, the valve on the serum discharge tube 4 at the top of the negative pressure separation test tube 1 should also be opened to ensure that the pressure in the negative pressure separation test tube 1 is the same as the external pressure. Then rotate the screwing head 10 to move the rubber piston 8 upward, so as to smoothly inhale the serum into the serum storage test tube 2. When the serum collection is completed, the corresponding valves can be closed and the conveying hose 6 can be removed. The serum storage test tube 2 can be directly placed in the refrigerator for storage, and the other substances at the bottom layer in the negative pressure separation test tube 1 can be put into the corresponding container through the liquid discharge tube 3 for subsequent processing.

[0025] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiments according to the technical essence of the present utility model still belong to the scope of the technical solution of the present utility model.
