Abstract

The invention discloses a medicine addition syringe. The medicine addition syringe comprises a syringe body. A piston is arranged in the syringe body. A needle cylinder base used for containing a needle is arranged at one end of the syringe body. The syringe body is communicated with a liquid outlet of the needle cylinder base. A sealing cover which can only be opened towards the inner portion of the syringe body is arranged above the liquid outlet of the needle cylinder base. A connection structure which can make liquid in the syringe body pass by the sealing cover and enter the needle cylinder base is arranged at the joint of the syringe body and the needle cylinder base. A filter membrane is arranged above the connection structure. Foreign matter and particles in injection can be filtered out through the medicine addition syringe, the filter effect of the medicine addition syringe is good, and the medicine addition syringe is simple in structure and low in machining cost.

Description

technical field [0001] The invention relates to the field of syringes, in particular to a medicine-feeding syringe. Background technique [0002] At present, the syringes equipped with filter membranes on the market generally use chemical fiber membranes, which have a spongy structure, which can effectively reduce the damage of the filter membrane due to excessive injection pressure, and can be used during intravenous injection and intravenous infusion. Filter out most of the foreign matter and particles in the injection, reducing the harm caused by foreign matter or particles entering the blood circulation system; in order to facilitate the process of drawing liquid, the filter membrane of this type of syringe is also equipped with a one-way opening into the syringe structure to speed up the pumping speed. However, during the injection process of the current syringe with a filter membrane, the filter membrane is under a relatively high injection pressure, and the one-way f...
