Abstract
A reuse-prevention disposable syringe is composed of a needle cylinder, a sealing ring and a piston rod, wherein the sealing ring is arranged at the front end of the piston rod and matched with the inner wall of the needle cylinder in a sealing mode, a clamping material is arranged at the rear end of the piston rod and connected with the piston rod through a material point, and the clamping material and the piston rod are in a breakable structure. After the syringe is used, people will discover that the syringe is already used if the syringe is reused, the cost is increased if the trace is required to be thoroughly eliminated to recover to the original state, and the recycling is unprofitable, so that the reuse of the disposable syringe is eliminated, the potential safety hazards of the people are eliminated, and lawful rights and interests of patients are protected; and the disposable syringe is simple in structure and quick and convenient to use.
Description
Technical field
This utility model relates to technical field of medical instruments, especially a kind ofly prevents reusable disposable syringe.
Background technology
Syringe is a kind of medical instruments, in order to liquid medicine injection or drawing liquid.According to purposes different styles and size are arranged, common is a circular hollow long tube, and scale is arranged outward, in join a sleeve (or claim piston).
As far back as the 15th century, Italian Ka Di Nellie just proposes the principle of syringe.But just carried out human trial for the first time up to British Danny Boyle in 1657 and reyn.The surgeon Abel of the French King Louis XVI (1774-1792 is in place) army also once dreamed up a kind of piston type syringe.But pula that it is generally acknowledged France is fertile to be the inventor of syringe now.The syringe that he supervised in 1853 is made of silver, and capacity has only 1 milliliter, and a screwed piston rod is arranged.
First uses glass syringe Englishman's Cathy Ferguson.The glass transparent degree is good, can see the situation of injectable drug.After this glass tubing metal is arranged and use the syringe of making, available boiling method sterilization, syringe needle also can sharpening reuse and sterilization.The danger that infects with once namely throwing away, takes place in the syringe plastics manufacturing of usefulness now when having significantly reduced injection.In order to guarantee health, prevent cross infection, the many employings of the syringe in the present age are plastic.
At present, disposable syringe structurally with the common syringe basically identical, after using, Policy Conditions according to country must be destroyed, but a lot of medical institutions carry out not according to the Policy Conditions of country, make it to repeat to re-use with the disposable syringe of crossing, give people's healthy great hidden danger and the insecurity brought.
The utility model content
The purpose of this utility model provides a kind of reusable disposable syringe that prevents, not only can stop disposable syringe and repeat to re-use, and removes people's potential safety hazard, and simple in structure, uses efficient and convenient.
The technical scheme that its technical problem that solves this utility model adopts is: a kind ofly prevent reusable disposable syringe, formed by syringe, sealing ring, piston rod, sealing ring is located at the front end of piston rod, with the inwall of syringe for being sealed and matched, the rear end of described piston rod is provided with and gets stuck, getting stuck is connected by the material point with piston rod, but is the turn-break type structure.
The beneficial effects of the utility model are: be provided with in the rear end of piston rod and get stuck; be the turn-break type structure but get stuck with piston rod, after syringe uses, reuse again and will be it is found that; thoroughly eliminating vestige if desired restores to the original state; can cause the increase of cost, recycling not only can be stopped disposable syringe and repeat to re-use profitless; remove people's potential safety hazard; safeguard patient's legitimate rights and interests, and simple in structure, use efficient and convenient.
Description of drawings

Fig. 2 is the structural representation after the disposable syringe combination.
1. syringes among the figure, 2. sealing ring, 3. piston rod 4. gets stuck.
The specific embodiment
As shown in Figure 1, a kind ofly prevent reusable disposable syringe, formed by syringe (1), sealing ring (2), piston rod (3), sealing ring (2) is located at the front end of piston rod (3), with the inwall of syringe (1) for being sealed and matched, the rear end of piston rod (3) is provided with get stuck (4), and get stuck (4) are connected by the material point with piston rod (3), but are the turn-break type structure.
As shown in Figure 2, when get stuck (4) on the piston rod (3) were not taken down, an end of get stuck (4) withstood the edge of syringe (1) plug mouth, and piston rod (3) can't all stretch in the syringe (1), have only get stuck (4) of twisting on the piston rod (3), syringe could use normally; And when get stuck (4) on the piston rod (3) are twisted, syringe can't return to original shape, will be considered as used syringe by people.
Claims (2)
1. one kind prevents reusable disposable syringe, is made up of syringe, sealing ring, piston rod, and sealing is located at the front end of ring piston rod, with the inwall of syringe for being sealed and matched, it is characterized in that: the rear end of described piston rod is provided with and gets stuck.
2. prevent reusable disposable syringe according to claim 1 is described, it is characterized in that: described getting stuck is connected by the material point with piston rod, but is the turn-break type structure.
