DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0029] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0030] Example:

[0031] Reference Figures 1-5, the embodiment of the present utility model provides a fingertip puncture blood collector, which includes a pipe fitting 1 with a cylindrical shape, and further includes: a partition plate 2 fixedly connected inside the pipe fitting 1; wherein, the pipe fitting 1 forms a blood collection cavity 3 and a device cavity 4 under the action of the partition plate 2, the blood collection cavity 3 and the device cavity 4 are respectively located at the upper and lower ends of the pipe fitting 1, and an extrusion component for squeezing the finger is provided at the inner top of the blood collection cavity 3; it further includes a jack 5 provided on the partition plate 2, and a puncture needle 6 for puncturing the finger is longitudinally slidably installed in the jack 5; wherein, the pointed end of the puncture needle 6 faces the inner top of the blood collection cavity 3, a pushing and puncturing component for driving the puncture needle 6 to move up and down is provided in the device cavity 4, and an end cover 11 for sealing the blood collection cavity 3 is threadedly connected to the upper end of the pipe fitting 1.

[0032] Analyzing the main technical solution of the above fingertip puncture blood collector, it can be seen that the fingertip puncture blood collector is mainly composed of a pipe fitting 1 with a cylindrical shape, a partition plate 2 fixedly connected inside the pipe fitting 1, a blood collection cavity 3, a device cavity 4, a jack 5, a puncture needle 6, etc.; when in use, first wipe and disinfect the finger to be blood collected, then insert the finger into the inner top of the blood collection cavity 3. At this time, the extrusion component will automatically squeeze the finger, and then the puncture needle 6 is moved upward and then downward to reset by the pushing and puncturing component. The puncture needle 6 can complete the rapid puncturing of the finger. After the finger is punctured, the squeezed finger can bleed and be automatically collected into the blood collection cavity 3. The whole operation process is simpler and more efficient, and can be completed quickly by personal independent operation. In this way, using the above fingertip puncture blood collector can improve the blood collection efficiency on the one hand and reduce the work intensity of medical staff on the other hand.

[0033] The above extrusion component includes an elastic plate 7 fixedly connected to the inner top of the blood collection cavity 3, and the radial cross-section of the elastic plate 7 is C-shaped.

[0034] Specifically, when the finger needs to be inserted into the blood collection cavity 3, the finger nail is oriented away from the elastic plate 7. So after inserting the finger, the elastic plate 7 will elastically press the finger pulp; this can eliminate the need for medical staff to complete the work of squeezing the finger, the operation is more efficient and labor-saving, and can reduce the probability of cross-infection.

[0035] The inner wall of the blood collection cavity 3 in the fingertip puncture blood collector is fixedly connected with a limiting plate 8 with a fan-shaped shape. The limiting plate 8 is arranged below the elastic plate 7 and is vertically staggered with the elastic plate 7, that is, the limiting plate 8 is not directly below the elastic plate 7.

[0036] Specifically, when the finger is inserted into the blood collection cavity 3, the fingertip and nail of the finger will be limited by the limiting plate 8, so that the extrusion position of the elastic plate 7 is more accurate and stable.

[0037] In the peripheral puncture blood sampler, the pushing and puncturing component includes a push plate 9 longitudinally and slidably connected in the device cavity 4. The lower end of the puncture needle 6 is fixedly connected to the push plate 9, and the push plate 9 is elastically connected to the inner top of the device cavity 4 through a spring 10.

[0038] Specifically, when it is necessary to puncture the finger, push the push plate 9 upward from the bottom of the pipe fitting 1. The push plate 9 can drive the puncture needle 6 to move upward to complete the puncture action. Then release the push plate 9, and the spring 10 will drive the push plate 9 to move downward and reset under the action of elastic force, so as to quickly and conveniently complete the finger puncture action. The whole process does not even require medical staff to operate.

[0039] The inner top of the above-mentioned end cap 11 is provided with a storage groove 12, and a disinfection sponge 13 is fixedly filled in the storage groove 12.

[0040] Specifically, before blood collection, the end cap 11 covers the top of the pipe fitting 1. When blood collection is needed, open the end cap 11, then press the finger against the disinfection sponge 13 and rotate the finger back and forth, and the finger disinfection work can be quickly completed. The whole process is simple to operate and can be independently completed by an individual, significantly improving the blood collection efficiency.

[0041] The inner top edge of the above-mentioned end cap 11 is fixedly connected with an elastic piece 15, and a circular baffle 14 is fixedly connected to the elastic piece 15; wherein, the edge of the circular baffle 14 is fixedly connected with a pressing plate 16. When the pressing plate 16 is not pressed by the pipe fitting 1, the baffle 14 will be inclined to the storage groove 12 under the action of the elastic piece 15.

[0042] Specifically, before blood collection, the end cap 11 covers the top of the pipe fitting 1, and the pressing plate 16 will be pressed by the upper port of the pipe fitting 1, so that the circular baffle 14 blocks the lower port of the storage groove 12 to prevent the disinfection sponge 13 from contaminating the blood sample after blood collection; when the end cap 11 is opened, the elastic piece 15 drives the circular baffle 14 to swing downward and incline under the action of elastic force, and the circular baffle 14 no longer blocks the storage groove 12, so the circular baffle 14 will not affect the user's use of the disinfection sponge 13.

[0043] The lower port of the above-mentioned device cavity 4 is fixedly connected with an annular plate 18 closely attached to the inner wall. The diameter of the annular plate 18 is larger than the diameter of the push plate 9. The annular plate 18 can block the lower edge of the push plate 9 to prevent the push plate 9 from running out of the device cavity 4.

[0044] The above-mentioned puncture needle 6 is eccentrically arranged in the blood collection cavity 3, and the tip of the puncture needle 6 is close to the elastic plate 7. Therefore, the puncture needle 6 can puncture the finger obliquely instead of puncturing the center position of the finger, and it can imitate the manual blood collection method to improve the blood collection efficiency.

[0045] A rubber sleeve 17 is fixedly connected to the outer wall of the lower end of the above-mentioned pipe fitting 1. An annular anti-slip pattern is provided on the outer wall of the rubber sleeve 17. The rubber sleeve 17 with an anti-slip pattern on the outer wall can improve the handling feel of the pipe fitting 1, thus facilitating the blood collection work.

[0046] Therefore, it can be said that the puncture blood collection device for peripheral vessels provided by the embodiment of the present invention has a simple structure but is novel and has high practical value.

[0047] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and the inventive concept of the present invention, making equivalent substitutions or changes, should be covered within the protection scope of the present invention.
