Description
Technical field
This utility model belongs to medical instruments field, is specifically related to a kind of safe syringe.
Background technology
Disposable syringe is widely used in various medical treatment situations, and it mainly is made up of entry needle, overcoat, core bar and piston, piston bush be contained in the core bar top and with overcoat inner surface interference fit.Therefore when reality was used, the frictional resistance between piston and the core bar was bigger, so sliding is bad.Secondly when medical personnel when extracting medicinal liquid with this syringe because product self can make that once in a while piston comes off from core bar, thereby have influence on medical worker's operation, waste medicinal liquid.Next is because some bad medical workers reuse syringe, causes viral cross infection, badly influences patient's health.
The utility model content
The purpose of this utility model is the deficiency that overcomes the existence of above-mentioned technology, the safe syringe that provide a kind of simple in structure, with low cost, can realize self-destruction.
This utility model for realizing the technical scheme that above-mentioned purpose adopted is:
A kind of safe syringe, it comprises needle tubing, overcoat, core bar and piston, said needle tubing is sleeved on the overcoat top; Suit core bar in the overcoat; This core bar top is set with piston, it is characterized in that said core bar top is provided with the stopping head, and overcoat liquid outlet inwall is provided with the stopping ring.
According to the described safe syringe of this utility model, it is characterized in that said stopping head is coniform.
According to the described safe syringe of this utility model, it is characterized in that said stopping ring is protruding ring-type, its lower surface is the inclined-plane, the upper surface is the plane.
This utility model is through being provided with the stopping head on the core bar top, and its external sleeve liquid outlet is provided with corresponding stopping ring, and therefore when core bar is shifted the overcoat end face onto after, the liquid outlet of the entering overcoat of only cutting somebody's hair also is stuck on the stopping ring of liquid outlet, thereby reaches the self-destruction purpose.This self-destruction syringe is compared ordinary syringe, and the advantage of following aspect is arranged: 1, this safe syringe can only use once, and just damage has automatically overcome the infection risk that brings to the patient because of the syringe repeated use effectively after the disposable use; 2, damage automatically after the disposable use of this syringe need not other extra operation, therefore makes things convenient for medical personnel to handle, and easy to operate.
The utlity model has advantages such as simple in structure, easy to operate, that cost is low, safety is good, have favorable economic benefit.

Fig. 3 is the core bar structure sketch map.
Among Fig. 2 figure: 1-needle tubing, 2-overcoat, 3-core bar, 4-stopping head, 5-stopping ring, 6-piston.
The specific embodiment
Elaborate below in conjunction with the technical scheme of accompanying drawing to this utility model:
As shown in Figure 1: a kind of safe syringe, it comprises needle tubing 1, overcoat 2, core bar 3 and piston 6.Said needle tubing 1 is sleeved on overcoat 2 tops, suit core bar 3 in the overcoat 2, and these core bar 3 tops are set with piston 6.Said core bar top is provided with stopping head 4, and this stopping head 4 is coniform.This stopping head 4 is be fixed on core bar 3 vertical, and passes piston.Overcoat 2 liquid outlet inwalls are provided with stopping ring 5, and this stopping ring 5 is protruding ring-type, and its lower surface is the inclined-plane, and the upper surface is the plane.Also be covered with helmet on the described generally speaking needle tubing 1.
This utility model is that its external sleeve liquid outlet middle part is provided with the stopping ring one, at the core bar head one coniform stopping head is arranged, as medical personnel during in clinical use; After injection finishes; The coniform stopping epicranium of core bar head pushes the stopping ring of overcoat, because of the stopping head is cone shape, can only get into to withdraw from; From design, prevent the repeated use of syringe fully, thereby realized the purpose of self-destruction.Avoid viral cross infection, guaranteed the clinical safe in utilization of syringe.And the use that this safe syringe is the same with ordinary syringe can not change the operation of medical workers custom, can not increase medical personnel's workload.
