Soft locking buckle type quantitative precision injector

Abstract

The invention provides a soft locking buckle type quantitative precision injector which comprises an outer sleeve and a core rod, a needle tube is arranged at the front end of the outer sleeve, a protective sleeve is connected to the outer side of the needle tube in a sleeving mode, the core rod is arranged on the inner side of the outer sleeve, a piston is arranged at the front end of the core rod, a hard clamping ring is arranged on the rear portion of the core rod, and a hard stopping buckle is arranged on the rear portion of the outer sleeve. When the core rod is pulled backwards, the hard clamping ring and the hard stopping buckle of the outer sleeve are stopped, a dosage clamping ring is arranged on the front portion of the core rod in a protruding mode, an elastic buckle is arranged on the inner side of the outer sleeve and inclines inwards from front to back, when the core rod is pulled backwards, the dosage clamping ring can pass through the elastic buckle, and when the core rod is pushed forwards, the elastic buckle stops the dosage clamping ring. The soft stop elastic buckle is arranged in the syringe outer sleeve, the amount of injection of the syringe is controlled, injected or transferred medicine can be accurately extracted, the detection precision of related instruments can also be improved, and medical accidents are prevented.

Description

technical field [0001] The invention relates to the technical field of syringes, in particular to a soft-stop snap-type quantitative precision syringe. Background technique [0002] Syringe is a device for injecting liquid medicine or withdrawing liquid. The syringe usually has a scale indication indicating the volume of liquid in the syringe. When the existing syringe is used for injection, the injection volume of the liquid is manually judged by the scale on the injection tube, which is greatly influenced by human beings, and it is easy to push the injection too far, resulting in an excessive one-time injection volume and causing medical accidents. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a kind of soft stop buckle type quantitative precision syringe. [0004] In order to achieve the above object, the technical scheme of the present invention is: [0005] A soft stop snap-type quantitative precision syringe, comprising a jack...
