[0012] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Please see Figures 1 to 3This embodiment provides a blood detection device for a blood brane in a blood separator, including a mounting panel 1. The mounting panel 1 allows the blood detection device to be directly and fixedly mounted onto the outer casing of the blood separator, enabling its use in conjunction with the blood separator. An outer casing 2 is fixedly mounted on the mounting panel 1. One end of the outer casing 2 is a mounting part 3, and the other end is a detection part 4. The mounting part 3 is fixedly connected to the mounting panel 1 by bolts. The detection part 4 extends from one side of the mounting panel 1 through the other side. A blood brane 5 is provided at the detection part 4, which is used to detect the flow of blood after centrifugation in the blood separator. A detection component is provided at the detection part 4 to detect the composition of the blood within the blood brane 5.

[0014] Specifically, the detection unit 4 of the outer casing 2 has a first cavity 6 and a second cavity 7, with a mounting groove 8 between the first cavity 6 and the second cavity 7. A first channel 12 is formed on one side of the first cavity 6, connecting it to the mounting groove 8. A second channel 13 is formed on one side of the second cavity 7, connecting it to the mounting groove 8. The central axis of the first channel 12 and the central axis of the second channel 13 are on the same straight line. The blood braid 5 cooperates with the mounting groove 8; during detection, the blood braid 5 is placed in the mounting groove 8, positioned between the first channel 12 and the second channel 13.

[0015] Specifically, the detection assembly includes a light-emitting element 9, a photosensitive element 10, and a signal circuit 11. The light-emitting element 9 is fixedly installed inside the first cavity 6 and encapsulated using an external fixing plate 14. The light-emitting element 9 emits detection light of a specific wavelength. The photosensitive element 10 is fixedly installed inside the second cavity 7 and encapsulated using an external fixing plate 14. The photosensitive element 10 receives the detection light passing through the blood vessel 5 and converts the light signal into an electrical signal. The photosensitive element 10 is electrically connected to the signal circuit 11. One end of the signal circuit 11, away from the photosensitive element 10, extends outward through the shell wall of the outer casing 2. The signal circuit 11 transmits the electrical signal to the control system, which determines the changes in blood components and cell types within the blood vessel 5 based on changes in light intensity.

[0016] Specifically, the working principle of this utility model is as follows: The blood detection device inside the blood braid is directly fixed to the outer shell of the blood separator through the mounting panel 1. After the wiring is connected, the blood braid 5 is placed in the mounting slot 8. After the blood is centrifuged and separated by the blood separator, it flows through the blood braid 5. The light-emitting element 9 emits detection light of a specific wavelength. The detection light passes through the first channel 12, the blood braid 5 and the second channel 13 in sequence. The photosensitive element 10 receives the detection light. When blood containing different components flows through the blood braid 5, the photosensitive element 10 will receive the light of a specific change, and then convert the light signal into an electrical signal. The signal line 11 transmits the electrical signal to the control system. The control system detects the blood components in the blood braid 5 in real time according to the intensity of the light.

[0017] Specifically, this blood braid internal blood detection device has a simple structure and is easy to install. It can be directly fixed to the outer shell of the blood separator via the mounting panel 1, enabling it to be used in conjunction with the blood separator. It reflects changes in blood composition within the braid 5 in real time through changes in light signals, eliminating the need for manual observation and providing strong real-time performance.
