[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] Reference Figures 1-5 As shown, this utility model provides a technical solution: a fingertip blood collection device, including a collection device body 1: a first storage groove 2 is provided at one end of the bottom of the collection device body 1, a third movable block 3 is slidably connected inside the first storage groove 2, a collection needle 4 is installed at the bottom of the third movable block 3, a connecting rod 5 is fixed on the surface of the third movable block 3, a stroke groove 6 is provided on one side of the collection device body 1 to cooperate with the connecting rod 5, a first control block 7 is fixed through the stroke groove 6 at the other end of the connecting rod 5, a first spring 17 is fixed at the top of the third movable block 3, the top of the first spring 17 is fixed to the top of the inner wall of the first storage groove 2, a sealing plate 26 is provided at the bottom of the collection device body 1, and a protective cover 25 is installed at the bottom of the collection device body 1 to cooperate with the sealing plate 26;

[0025] A limiting component is provided on one side of the collector body 1. The limiting component includes a groove 9 formed on one side of the collector body 1. A through groove 13 is formed inside the groove 9. A second movable block 15 is slidably connected inside the through groove 13. A first slot 14 that cooperates with the second movable block 15 is formed on one side of the third movable block 3. A first movable block 10 is slidably connected inside the groove 9. Slider blocks 12 are fixed on both sides inside the groove 9. Sliding grooves 11 that slidably connect with the sliders 12 are formed on both sides of the first movable block 10. A slot 16 that cooperates with the first movable block 10 is formed on the top of the second movable block 15. The second movable block 15 is located away from the first movable block 10. One end of the third movable block 3 is fixed with a second control block 18, and both ends of the second control block 18 are fixed with tension springs 19. The other end of the tension springs 19 is fixed to the collector body 1. The top of the first movable block 10 is fixed with a second spring 20, and the top of the second spring 20 is fixed to the top of the groove 9. A friction block 21 is provided on one side of the first movable block 10. The user removes the protective cover 25, places the collector body 1 on his finger, and then controls the first movable block 10 to move upward, causing the bottom of the first movable block 10 to disengage from the slot 16, releasing the restriction on the second movable block 15. When the first movable block 10 moves, the friction block 21 is released. The sliding connection between the slide groove 11 and the slider 12 prevents the first movable block 10 from shifting. The push generated by the tension spring 19 on the second control block 18 causes the second control block 18 to pull the second movable block 15 out of the first slot 14, releasing the restriction on the third movable block 3. The thrust generated by the first spring 17 pushes the third movable block 3 to move the collection needle 4 downward, pricking the finger with the collection needle 4 to facilitate blood collection. After collection, the protective cover 25 is installed on the bottom of the collector body 1. The contact between the protective cover 25 and the collection needle 4 causes the third movable block 3 to retract into the first storage slot 2. Inside, the second control block 18 controls the second movable block 15 to insert into the first slot 14, limiting the position of the third movable block 3. Then, the first movable block 10 is controlled to move downward, so that the first movable block 10 is inserted into the slot 16, limiting the second movable block 15. The second spring 20 prevents the first movable block 10 from detaching from the slot 16. Through the integrated design, the collector is integrated into a single unit, making the collector a disposable device. After use, a new one can be taken out and used again, avoiding the risk of cross-infection caused by negligence in the repeated replacement of the sampling head.

[0026] Reference Figure 3As shown in this embodiment: a second storage slot 22 is provided at the other end of the bottom of the collector body 1. A collection tube 23 is slidably connected inside the second storage slot 22. By opening the second storage slot 22, the collection tube 23 is installed inside the collector body 1. After the collection needle 4 pricks the finger, blood can be collected directly through the collection tube 23, reducing the cumbersomeness of operation.

[0027] Reference Figure 3 and Figure 5 As shown in this embodiment: a first protective pad 24 for use with the collection tube 23 is installed at the top of the second storage slot 22; a sealing plug 27 for use with the collection tube 23 is installed at one end of the protective cover 25; a second slot 28 is opened at the top of the sealing plug 27; and a second protective pad 29 for use with the collection needle 4 is installed at the other end of the protective cover 25. The first protective pad 24 and the sealing plug 27 protect the collection tube 23 and prevent it from being damaged. The sealing plug 27 seals the collection tube 23 by connecting it to the second slot 28, preventing the collection tube 23 from shifting. The second protective pad 29 protects the collection needle 4.

[0028] Reference Figure 1 As shown in this embodiment: a label slot 30 is provided on one side of the collector body 1. The label slot 30 allows for the pasting of labels, making it easier for staff to identify the labels.

[0029] Reference Figure 1 As shown in this embodiment: an observation slot 31 is provided on one side of the collector body 1, which penetrates the second storage slot 22. The observation slot 31 is provided to facilitate the observation of the collection volume of the collection tube 23.

[0030] Working principle: The user removes the protective cover 25, places the collector body 1 on their finger, and then controls the first movable block 10 to move upward, causing its bottom to disengage from the slot 16, thus releasing the restriction on the second movable block 15. During the movement of the first movable block 10, the sliding connection between the slide groove 11 and the slider 12 prevents deviation. The push generated by the tension spring 19 on the second control block 18 causes the second control block 18 to pull the second movable block 15 out of the first slot 14, releasing the restriction on the third movable block 3. The thrust generated by the first spring 17 pushes the third movable block 3, causing the collection needle 4 to move downward, pricking the finger to facilitate blood collection. After collection, the protective cover 25 is installed at the bottom of the collector body 1. The protective cover 25 abuts against the collection needle 4, causing the third movable block 3 to retract into the first storage slot 2. The second movable block 15 is inserted into the first slot 14 by the second control block 18, limiting the position of the third movable block 3. Then, the first movable block 10 is moved downward so that it is inserted into the slot 16, limiting the second movable block 15. The second spring 20 prevents the first movable block 10 from dislodging from the slot 16. The collection tube 23 is installed into the collector body 1 through the opening of the second storage slot 22. After the collection needle 4 pricks the finger, blood can be collected directly through the collection tube 23, reducing the complexity of the operation.

[0031] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
