[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Reference Figure 1-Figure 3The utility model provides an embodiment: a finger blood collection device, including a shell 1. When blood collection is required, the shell 1 is taken out. The left and right sides of the shell 1 are fixedly connected with rubber strips 17. The outside of the rubber strip 17 is fixedly connected with multiple anti-slip strips 18. Holding the outside of the rubber strip 17, the rubber strip 17 and the anti-slip strip 18 can prevent slipping and maintain the stability of holding. The bottom of the shell 1 is provided with a sliding groove 2. The inside of the sliding groove 2 is slidably connected with a base 8. Then the base 8 is placed in the inside of the sliding groove 2. Then the base 8 is pressed upward with force. The left and right sides of the bottom of the shell 1 are provided with a cavity 3. The inner wall of the cavity 3 is slidably connected with a sliding column 4. The outside of the sliding column 4 is slidably connected to the external through hole of the shell 1. The outside of the sliding column 4 is sleeved with a spring 6, and the spring 6 will be compressed by force.

[0033] One end of a spring 6 is fixedly connected to one side of the interior of a cavity 3, and the other end of a spring 6 is fixedly connected to one side of a card block 5. The two sliding columns 4 are fixedly connected to the opposite sides with baffles 7, which can limit the sliding columns 4. A needle 11 is provided at the bottom of the base 8, and then the needle 11 is placed in the bottom of the base 8 and squeezed upward. An adjusting component is provided at the top of the base 8, and the adjusting component includes two card blocks 5, a card plate 9 and a slide plate 10. The outside of the card block 5 is slidably connected to the inner wall of the cavity 3, and the top of the base 8 is fixedly connected with a card plate 9. At this time, the card plate 9 will squeeze the card block 5 to both sides, and the card block 5 will be forced to expand to both sides. As the base 8 moves, the top of the card block 5 will contact the bottom of the card plate 9, so that the base 8 can be installed at the bottom of the shell 1.

[0034] After that, the patient's blood is drawn through the needle 11. At this time, the needle 11 needs to be pressed, and the base 8 will slide inside the sliding groove 2. One side of the block 5 is fixedly connected to the side away from the baffle 7. When the card plate 9 contacts the block 5, the needle 11 stops moving, and the needle 11 will pierce the patient's skin and then draw blood. Each time the block 5 contacts the card plate 9, blood can be drawn from the patient. The distance in between can prevent the needle 11 from piercing the patient's skin more deeply. The outside of the base 8 is slidably connected with a slide plate 10. Pressing the needle 11 twice in a row will cause the block 5 to contact the bottom of the slide plate 10. At this time, the block 5 will slide along the outside of the slide plate 10, and the base 8 can be removed for replacement and maintenance. The piercing depth of the base 8 can be controlled to ensure that the needle 11 will not pierce too deep during blood collection.

[0035] Reference Figure 1-Figure 3A plurality of locking components are arranged inside the base 8, and the locking components include a cavity 12, a spring 13, a limit plate 14 and a rubber ball 15. As the needle 11 moves, it will contact the rubber ball 15. The cavity 12 is opened inside the base 8, and the outside of the limit plate 14 is slidably connected to the inner wall of the cavity 12. The other side of the limit plate 14 is fixedly connected to the rubber ball 15. The limit plate 14 can limit the spring 13. At this time, the rubber ball 15 is forced to squeeze the limit plate 14 inward, and the outside of the rubber ball 15 is slidably connected to the inner wall of the cavity 12.

[0036] A plurality of slots 16 are provided on the outside of the needle 11, and the outside of the rubber ball 15 is engaged with the inner wall of the slot 16. Then, the needle 11 is rotated, and a spring 2 13 is fixedly connected to one side of the inside of the cavity 2 12. At the same time, the spring 2 13 will be compressed inside the cavity 2 12. The other end of the spring 2 13 is fixedly connected to the limit plate 14, and a reaction force is generated on the limit plate 14. When the rubber ball 15 contacts the slot 16, the spring 2 13 will release the external force absorbed during compression, so that the rubber ball 15 and the slot 16 are more tightly engaged, so that the needle 11 can be installed at the bottom of the base 8, and the needle can be quickly replaced to maintain hygiene during blood collection.

[0037] Working principle: when blood sampling is needed, take out the shell 1, hold the outside of the rubber strip 17, the rubber strip 17 and the anti-slip strip 18 can prevent slipping and maintain the stability of holding, then place the base 8 into the inside of the sliding groove 2, then put the needle 11 into the bottom of the base 8, squeeze the needle 11 upward, as the needle 11 moves, it will contact the rubber ball 15, at this time the rubber ball 15 is forced to squeeze the limit plate 14 inward, and at the same time the spring 2 13 is forced to be compressed inside the cavity 2 12, then rotate the needle 11, when the rubber ball 15 contacts the card slot 16, the spring 2 13 will release the external force absorbed during compression, and generate a reaction force on the limit plate 14, so that the rubber ball 15 and the card slot 16 are more tightly engaged, so that the needle 11 can be installed at the bottom of the base 8, then squeeze the base 8 upward with force, at this time the card plate 9 will move to both sides Squeeze the card block 5, the card block 5 is forced to expand to both sides, at this time the spring 1 6 is compressed, with the movement of the base 8 the top of the card block 5 will contact with the bottom of the card plate 9, the base 8 can be installed on the bottom of the shell 1, and then the patient's blood is drawn through the needle 11. At this time, the needle 11 needs to be pressed, and the base 8 will slide inside the sliding groove 2. When the card plate 9 contacts the card block 5, the needle 11 stops moving, the needle 11 will pierce the patient's skin and then draw blood. Each time the card block 5 contacts the card plate 9, blood can be drawn from the patient. The distance in between can prevent the needle 11 from piercing the patient's skin more deeply. Pressing the needle 11 twice in a row will cause the card block 5 to contact with the bottom of the slide plate 10. At this time, the card block 5 will slide along the outside of the slide plate 10, and the base 8 can be removed for replacement and maintenance.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
