Embodiment Construction
[0019] see figure 1 with figure 2 , a low-resistance piston assembly for a syringe, which is used to form a low-resistance syringe with a jacket 1 used in conjunction with it and a push rod 2 connected with the piston assembly. Wherein, the piston assembly includes a piston 3 and a connecting head 4 sheathed in the piston 3 . The piston assembly is in sealing sliding connection with the inner hole of the outer casing 1, and a front cavity 101 at the front end of the piston assembly and a rear cavity 102 at the rear end of the piston assembly are formed in the inner hole of the outer casing 1.
[0020] see image 3 with Figure 4 , the piston 3 is sheathed on a neck 402 of the connecting head 4 through the piston inner hole 303 in the middle of the piston. A recess 301 is provided at the head end of the piston 3 , and a lip 302 is provided on the outer periphery of the recessed end of the piston 3 . Two sealing protruding rings 304 are arranged near the depression in the ...
