(1) the sealing rubber pad is sleeved on the position, located at the bottom of the inner surface of the indwelling needle connecting seat, of the outer surface of the plunger pipe column, so that when the sealing cover is matched with the indwelling needle connecting seat, the sealing performance of a space is formed by the plunger pipe column, the sealing cover and the sealing rubber pad, and the situation of liquid leakage at an interface when the indwelling needle connecting seat is matched with the indwelling needle can be avoided;
(2) the right end of the top plug pipe column is attached with a sealing film, the sealing film extends to the middle position of the outer surface of the top plug pipe column, and the sealing film has the function of preventing the sealing cover from being not tightly matched with the indwelling needle connecting seat to cause pollution in the infusion tube;
(3) the left side of the inner surface of the right end of the sealing cover is provided with a sterilized cotton pad, the right end of the sealing cover is provided with a sealing plug, before the remaining needle connecting seat is matched with the remaining needle, an infusion interface of the remaining needle needs to be sterilized, the infusion interface of the remaining needle is contacted with the sterilized cotton pad and rotates after the sealing plug is pulled out, and the sterilization is completed, so that the sterilization of a nurse is facilitated, and meanwhile, the time wasted by forgetting to take the sterilized cotton by the nurse and needing to take the sterilized cotton again can be saved;
(4) the risks of liquid leakage, connection falling and the like caused by mismatching of the connection of the indwelling needle and the infusion apparatus are overcome;
(6) the medical waste caused by discarding the steel needle infusion apparatus when the indwelling needle is butted is reduced, the personnel are prevented from being punctured, the resources are saved, and the environment is effectively protected.
