[0002] Neonatal heel blood screening refers to the examination of heel blood collected 72 hours after the baby is born. It is mainly aimed at diseases with high incidence, no obvious symptoms in the early stage but with positive laboratory indicators, which can be diagnosed and treated. Early detection, diagnosis and treatment in the neonatal period can avoid serious harm to the newborn. Based on the existing technology, it is found that the traditional heel blood collection method has some inconveniences. During the blood collection process, medical staff usually need to fix the feet of the newborn, which is not only cumbersome to operate, but also the newborn is prone to crying due to discomfort, causing the feet to shake unconsciously, thus affecting the smooth progress of the blood collection operation.

[0034] Embodiment three: Based on the second embodiment, according to Figure 7-Figure 8 As shown, it also includes a test paper clamping system; each telescopic rod II 302 is connected to a test paper clamping system; each test paper clamping system is composed of a mounting plate 401, a cylinder 402, a fixing plate II 403, a paddle 404, an ejector pin 405, an elastic member II 406 and a rubber strip 407; the telescopic part of the telescopic rod II 302 is movably connected to the mounting plate 401; the mounting plate 401 is fixedly connected to the cylinder 402; the outer side of the cylinder 402 is fixedly connected to the fixing plate II 403 ; A paddle 404 is slidably connected to the fixed plate Ⅱ403; a plurality of ejector pins 405 are fixedly connected to the lower part of the paddle 404; all ejector pins 405 are slidably connected to the fixed plate Ⅱ403; an elastic member Ⅱ406 is sleeved on the outside of each ejector pin 405, and the elastic member Ⅱ406 is a spring, and one end of the elastic member Ⅱ406 is fixedly connected to the paddle 404; the other end of the elastic member Ⅱ406 is fixedly connected to the fixed plate Ⅱ403; two rubber strips 407 are fixedly connected to the outside of the cylinder 402.

[0035] The blood sampling test strip is placed on the outside of the cylinder 402 in advance. When placing the blood sampling test strip, the medical staff pulls the paddle 404 to move upward, and the movement of the paddle 404 drives all the ejector pins 405 to move upward, thereby compressing all the elastic parts II 406, and then the upper end of the blood sampling test strip is pressed against the fixed plate II 403 and located below all the ejector pins 405. The paddle 404 is then released, so that all the ejector pins 405 move downward to press against the upper end of the blood sampling test strip, and the elastic force generated by all the elastic parts II 406 makes all the ejector pins 405 clamp and limit the upper end of the blood sampling test strip, and then the blood sampling test strip is straightened from top to bottom along the outside of the cylinder 402, and the back of the blood sampling test strip is glued by two adhesive strips 407, so as to achieve limiting and fixing of the entire blood sampling test strip.

[0036] Then, after the blood collection needle punctures the sole of the newborn, the medical staff pushes the mounting plate 401 to move, and the movement of the mounting plate 401 drives the cylinder 402 to move, and the movement of the cylinder 402 drives all the connected parts to move, so that the blood collection test paper moves toward the blood collection needle, and the blood collection test paper is aligned with the bleeding position of the sole of the newborn. Then, the medical staff rotates the telescopic rod II 302 to the right, and the telescopic rod II 302 rotates to the right to drive all the connected parts to move, so that the blood collection test paper moves to the right and presses against the bleeding position of the sole of the newborn, so that the blood on the sole of the newborn drips on the blood collection test paper, and then continues to push. The movable mounting plate 401 moves, and the movement of the mounting plate 401 drives all the connected parts to move, so that the blood sampling test paper continues to move until the blood sampling operation is completed, and because the rotation position of the telescopic rod Ⅱ302 in the up and down directions is locked, the blood sampling test paper can move along the telescopic rod Ⅱ302, so that the blood sampling test paper can quickly align with the bleeding position of the sole of the newborn, thereby improving the accuracy of blood sampling, and making the blood sampling test paper become curved on the cylinder 402, which can facilitate medical staff to observe the bleeding position of the sole of the newborn and the blood collection position of the blood sampling test paper, further improving the accuracy of the blood collection position.

[0037] After the blood collection is completed, when the telescopic rod II 302 is reset, the medical staff twists the connecting rod 304 with one hand to make the connecting rod 304 rotate. The rotation of the connecting rod 304 drives the limiting hook 305 to rotate and compresses the elastic member I 307, so that the limiting hook 305 rotates and disengages from the ratchet 303, thereby releasing the limit on the ratchet 303, so that the telescopic rod II 302 can rotate up and down until the telescopic rod II 302 rotates downward and resets, and then the telescopic rod II 302 contracts, and then the cylinder 402 moves and resets, thereby driving all the connected parts to move and reset for the next use.
