[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0016] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, if the terms "first", "second", and "third" are used, they are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0017] As shown in the figure, the one-handed handheld neonatal plantar blood collection device includes a cylinder 1, a cover 2, and a needle 3. The cylinder 1 is a cylindrical structure with openings at both ends, the cover 2 is located on one side of the cylinder 1, and the cover 2 is a truncated cone structure with openings at both ends. A partition 11 is provided inside the cylinder 1, and a through hole is provided at the center of the partition 11. A pressing component is also provided in the cylinder 1, and the pressing component includes a piston plate 4, a telescopic spring 5 and a pressing block 6. The piston plate 4 is located in the cylinder 1, and the needle 3 is fixed on the piston plate 4. One end of the telescopic spring 5 is fixedly connected to the partition 11, and the other end is fixedly connected to the piston plate 4. The other end of the piston plate 4 is fixed with a pressing block 6. When the medical staff presses the pressing block 6 downward, the pressing block drives the piston plate 4 to move downward, and then drives the needle 3 to move downward, and the needle 3 performs acupuncture on the blood collection site of the human body. After releasing the hand, the piston plate 4 rebounds under the drive of the telescopic spring 5, driving the needle 3 away from the human body. Figure 2 .

[0018] Specifically, a limit block is provided inside the cylinder 1, and the piston plate 4 is provided between the limit block and the partition plate 11, wherein the limit block is used to limit the piston plate 4 from moving outward.

[0019] Specifically, the number of the telescopic springs 5 ​​is two, wherein the telescopic springs 5 ​​are used to limit the downward movement distance of the piston plate 4 and reset it.

[0020] Specifically, the cylinder body 1 and the cover body 2 are made of medical plastic material.

[0021] Specifically, an external thread is provided on one side of the barrel 1 close to the pressing block 6, and the blood collection device also includes a cap with an internal thread. The cap is threadedly connected to the barrel 1, and the cap is mainly used to cover the pressing block 6 to prevent the needle 3 from being accidentally touched.

[0022] The utility model has a firm structure to prevent accidental touch, and the needle 3 is fixed inside the cylinder 1 and is not easy to be observed, thereby reducing the fear of the person whose blood is drawn to seek medical treatment. At the same time, the cover 2 in front of it can effectively fix and squeeze the blood collection site, wherein the piston plate 4 can move up and down inside the cylinder 1 to drive the needle 3 to move downward. Figure 2 When the medical staff presses the pressing block 6 downward, since the distance between the piston plate 4 and the partition 11 is fixed, the length of the needle 3 after being pressed down is fixed, thereby effectively controlling the depth of the needle 3 inserted into the part to be blood drawn, and the design is reasonable.

[0023] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
