Abstract
The utility model relates to a clamp-in type self-destroying injector and belongs to the technical field of medical equipment. The clamp-in type self-destroying injector comprises a needle, a needle cylinder, a casing pipe, a push-and-pull rod, a piston and an extruding board. The clamp-in type self-destroying injector is characterized in that corrugated protrusions are arranged on the outer wall of the needle cylinder with the needle connected with the front end, anti-skidding strips are arranged on the corrugated protrusions, and the rear end of the needle cylinder is communicated with the casing pipe, wherein the inner diameter of the casing pipe is larger than that of the needle cylinder; the piston is fixedly connected on the periphery of the front end of the push-and-push rod, the length of the push-and-pull rod is identical to that of the needle cylinder, the rear end of the push-and-push rod is fixedly connected with the extruding board, the outer diameter of the extruding board is matched with the inner diameter of the casing pipe, and the thickness of the extruding board is identical to the length of the casing pipe. The clamp-in type self-destroying injector is simple in structure, convenient to use and low in manufacturing cost. After injection of a patient is completed, the extruding board connected with the rear end of the push-and-pull rod is clamped in the casing pipe and can not be pulled out, so that the injector is prevented from being used again, and health of human bodies is guaranteed.
Description
Technical field: this utility model belongs to the medical instruments technical field, is a kind of snap-in self-destroyed syringe specifically.
Background technology: at present, employed syringe mainly is made up of needle tubing, piston, push rod and injection needle clinically, and this syringe is thrown away in garbage basket conveniently mostly after finishing using and handled together with medical waste.Be easy to like this be utilized again, thereby cause cross infection, serious threat human health.Though various self-destruction syringes are arranged now, because complex structure, production cost height, operation easier big etc. can't apply mostly by reason for these self-destruction syringes.
Summary of the invention: the purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of simple in structure, easy and simple to handle, can avoid the snap-in self-destroyed syringe that is utilized again after finishing to patient injection.
The technical solution of the utility model is: this snap-in self-destroyed syringe comprises syringe needle, syringe, sleeve pipe, push-pull bar, piston, stripper plate, the syringe outer wall that front end is connected with syringe needle is provided with wavy bulge, be provided with anti-skidding striped above the wavy bulge, back end of syringe is connected with the sleeve pipe of internal diameter greater than the syringe internal diameter; Fixedly connected piston around the push-pull bar front end identical with syringe length, the rear end fixedly connected the stripper plate that adapts of external diameter and casing inner diameter, stripper plate thickness is identical with casing length.
Advantage of the present utility model: simple in structure, easy to use, cost of manufacture is low, and after finishing to patient injection, the stripper plate that the push-pull bar rear end connects can snap in the sleeve pipe and can't extract, and can prevent that syringe from being utilized again, guarantees that people's is healthy.
Description of drawings: Fig. 1 is structure cutaway view of the present utility model.
The specific embodiment: describe in further detail below in conjunction with this utility model of Fig. 1: this snap-in self-destroyed syringe comprises syringe needle 1, syringe 2, sleeve pipe 3, push-pull bar 4, piston 5, stripper plate 6, syringe 2 outer walls that front end is connected with syringe needle 1 are provided with wavy bulge, be provided with anti-skidding striped above the wavy bulge, syringe 2 rear ends are connected with the sleeve pipe 3 of internal diameter greater than syringe 2 internal diameters; Fixedly connected piston 5 around push-pull bar 4 front ends identical with syringe 2 length, the rear end fixedly connected the stripper plate 6 that adapts of external diameter and sleeve pipe 3 internal diameters, stripper plate 6 thickness are identical with sleeve pipe 3 length.
