Detailed ways

Below in conjunction with accompanying drawing and embodiment the present invention is further described:

The filiform needle ejector shown in Fig. 1, Fig. 2, Fig. 3 and Fig. 4 includes a sleeve body 1 and an upper small and a lower large skirt 3 communicating with the sleeve body 1; Squeeze the filiform needles and make it easy to observe the situation of the filiform needles 5 in the needle ejector. The sleeve body 1 and the skirt 3 are made of transparent and soft materials; in this embodiment, the materials of the sleeve body 1 and the skirt 3 are Transparent soft silica gel, in other present embodiment sleeve body 1 and the material of retaining skirt 3 can adopt transparent soft plastic or have the material of same property. The sleeve inner hole 2 in the sleeve body 1 is small at the top and large at the bottom. The diameter of the smallest cross-section of the inner hole 2 of the sleeve is greater than 5 mm, which is larger than the diameter of the largest diameter of the currently used needles. The shape of the inner hole of the sleeve in this embodiment is a cone platform; in order to conveniently and quickly press the skirt 3 to the human skin 6 when the needle is out, the wall thickness of the skirt 3 gradually becomes thinner from the skirt head to the bottom of the skirt, and a strip is provided on the opposite sides of the skirt to the bottom of the skirt. Vertically penetrate the gap 4 at the bottom of the skirt; in order to ensure that the tip of the needle is blocked in the skirt 3 after the needle is released, the height L2 of the skirt 3 is greater than 25 mm, which is greater than the normal needle insertion depth L1 of the human body: 15- 20 mm.

When using the present invention, cover the sleeve body 1 and the skirt 3 with the needle 5 that is stuck in the human body and press the skirt 3 to the human skin 6, as shown in Figure 3; then pinch the skirt 1 with your fingers Hold the filiform needle 5 in the sleeve body 1, as shown in Figure 4, the direction of force is F direction, then pull out the filiform needle 5 and continue to pinch the filiform needle; the pulled out filiform needle is held above the sharps collection box, and then loosen and pinch the sleeve The needles will automatically fall into the collection box, so as to avoid the medical staff, patients or surrounding people being stabbed by the needles, and also avoid contact with the pulled out needles, thereby reducing the possibility of infectious diseases.
