Description
Technical field
This utility model relates to the medical apparatus technical field, a kind of specifically disposable safety self-ruined syringe.
Background technology
Along with deepening continuously and the people's living standard and improving constantly of environmental consciousness of China's reform and opening-up, broad masses of the people require also improving constantly to the safe handling of medical service level and medical supplies.For reduce the cross infection that medical apparatus and instruments brings when using repeatedly, particularly to stop disposable syringe and sold illegally and secondary use phenomenon, national departments concerned has been taked some active measure, has obtained certain effect.But,, also exist many leaks so fundamentally change this nonexpondable present situation because the present disposable syringe product that uses can't be accomplished truly " disposable use (self-destruction) ".Particularly in recent years, domestic disposable syringe is sold illegally with secondary and is used phenomenon very serious.Because these problems directly influence the healthy of numerous people, have damaged patient's safety and interests greatly.World Health Organization (WHO) and domestic relevant department and some experts have proposed to use the proposal of self-destruction syringe the eighties in last century.
At present, mass selling and at the common disposable syringe of remaining of clinical use on the market is not because it possesses the function of self-destruction type, particularly because the illegal existence of reclaiming, using phenomenon does not repeatedly have real " disposable " specification requirement.In clinical use and harmless treatment thereafter, there are serious problems.In order really to reach disposable purpose, the someone has attempted multiple self-destruction scheme.For example, water-swellable, a dress watt reed are ruined type, elastic component and are ruined to contract in type, the syringe needle and ruin that type, needle-penetration are ruined type, type, the telescopic type etc. of ruining of retaining are ruined in the element fracture.But in the production and clinic trial of reality, or meet the deliquescence body easily and be difficult for long-term storage because of expanding material exists, or problem because of adopting hardware to get rusty easily, or because of the complicated difficult shortcomings such as inconvenience, production cost height of producing, assemble of design technology, its research and production work have run into certain resistance.But in order thoroughly to stop the repeated use of disposable syringe, fundamentally protect people's life and health, must design the disposable syringe that a kind of safety well can self-destruction.
The utility model content
The purpose of this utility model is that design is a kind ofly avoided reusing, safe and reliable disposable safety self-ruined syringe.
This utility model disposable safety self-ruined syringe comprises: syringe assembly and shank assembly, and described syringe assembly comprises plastic needle cylinder 3, and syringe needle is sleeved on the cone needle stand 7 hermetically, and outer being set with protected pin medicated cap 8 on the syringe needle; Described shank assembly, comprise plastic push-rod 2, plastic push-rod 2 left ends are provided with promotion dish 11, safety plate 1, and plastic push-rod 2 right-hand members are provided with guide ring 10, silica gel sealing piston 5 is sleeved on the right side of the guide ring 10 of plastic push-rod 2, and is blocked by the frustum 9 on silica gel sealing piston 5 right sides; The right-hand member of plastic push-rod 2 is provided with fluting latch 6.
Described fluting latch 6 is the elasticity latch, and is pre-small post-large.
Described plastic needle cylinder 3 fluid places are the inner conical pipe.
This utility model disposable safety self-ruined syringe is achieved in that at first opens safety plate 1, extracts required liquid medicine injection, can inject; In the process of injection, fluting latch 6 point diameters are less than the minimum diameter of plastic needle cylinder 3, can pass through the inner conical pipe at plastic needle cylinder 3 fluid places smoothly, when injection was finished, plastic push-rod 2 was pushed to the top, and fluting latch 6 has passed the inner conical pipe at plastic needle cylinder 3 front end fluid places, and the diameter of the rear end of fluting latch 6 is greater than the external diameter of the inner conical pipe at plastic needle cylinder 3 fluid places, plastic push-rod 2 will be stuck this moment, and silica gel sealing piston 5 can not be return, and reaches self-destruction.
The advantage of this utility model disposable safety self-ruined syringe is: really realizes self-destroying function, effectively prevents to reuse that safe and reliable, technology is simple, be easy to produce, and easy to assembly, low production cost.
Description of drawings
Fig. 1 is the structural representation of disposable safety self-ruined syringe.
The specific embodiment
According to shown in Figure 1, a kind of disposable safety self-ruined syringe comprises: syringe assembly and shank assembly, and described syringe assembly comprises plastic needle cylinder 3, and syringe needle is sleeved on the cone needle stand 7 hermetically, and outer being set with protected pin medicated cap 8 on the syringe needle; Described shank assembly, comprise plastic push-rod 2, plastic push-rod 2 left ends are provided with promotion dish 11, safety plate 1, and plastic push-rod 2 right-hand members are provided with guide ring 10, silica gel sealing piston 5 is sleeved on the right side of the guide ring 10 of plastic push-rod 2, and is blocked by the frustum 9 on silica gel sealing piston 5 right sides; The right-hand member of plastic push-rod 2 is provided with fluting latch 6.
Described fluting latch 6 is the elasticity latch, and is pre-small post-large.
Described plastic needle cylinder 3 fluid places are the inner conical pipe.
