Abstract
The utility model relates to a disposable aseptic irradiation-resistant syringe. The disposable aseptic irradiation-resistant syringe comprises an outer cover, a push rod, a piston, an injection needle with a needle sleeve, and a packaging bag without dialyzing paper. The outer cover, the push rod and the needle sleeve are all made of medical irradiation-resistant polypropylene materials in injection molding mode, and the packaging bag without the dialyzing paper is made of polyester composite materials in blow molding mode. Sterilization can be carried out to the disposable aseptic irradiation-resistant syringe through high-power electron beams, and therefore environment pollution caused by sterilization through ethylene oxide can be avoided; resolving is not needed after irradiation sterilization, and the disposable aseptic irradiation-resistant syringe has the advantages of being complete in sterilization, free of pollution, free of residual, long in retention time, and the like; and the disposable aseptic irradiation-resistant syringe is safe, simple, nontoxic and long in retention time.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, specifically the aseptic syringe of anti-irradiation of a kind of disposable use.
Background technology
So far, in the world the sterilization method of medical supplies is mainly contained three kinds of conventional heating (steaming and decocting, steam) sterilization, chemical disinfection and irradiation sterilizations.Heating disinfection, energy consumption is large, and it is not thorough to sterilize, inapplicable to the goods of thermo-labile easy tide.Chemical disinfection, such as traditional epoxyethane sterilization, general cost is higher, causes easily atmospheric pollution and the defective of residual harmful chemicals on medical apparatus and instruments.Disposable use polypropylene syringe with ethylene oxide sterilizing, if oxirane can not get discharging timely and effectively (for example depositing) under the low temperature and moisture environment, may produce potential harm to patient and medical personnel in use, for example nervous system damage and chronic toxicity (Feng Liqi, Wang Shuqin, the harm of oxirane and the protection safety in the Disinfection Work in Hospital, " Journal of Nursing Science ", in December, 2006,21 volumes, 12 phases, 67-70).Utilizing the method for irradiation that medical apparatus and instruments is carried out disinfection is a kind of new method that development in recent years is got up, and becomes the new focus in medical apparatus sterilizing field.The same two kinds of methods are compared, and radiosterilization has the advantages such as sterilization is thorough, noresidue, the saturating bacterium of packaging material, and the holding time long (can reach 2 to 5 years) is the most promising sterilization method in the world today.Irradiation sterilization generally has gamma ray and two kinds of methods of electron beam, and with respect to gamma ray, and electron beam has safety, pollutes without radioactive source, and radiation dose rate is large, finish the advantages such as sterilization speed is fast, is to have the irradiance method of sterilizing on a large scale most.
Summary of the invention
This utility model is energy consumption is large and chemosterilization exists contaminated environment, the residual harmful shortcoming such as chemical substance that exists in order to overcome heat sterilization, provide a kind of simple in structure, form rationally, available high-power electron beam sterilization, sterilize thorough, pollution-free, noresidue, the aseptic syringe of anti-irradiation of disposable use that the holding time is long.
The technical scheme that this utility model addresses the above problem employing is: the aseptic syringe of anti-irradiation of disposable use, comprise overcoat, push rod, piston and with entry needle, the packaging bag of needle guard, it is characterized in that described overcoat, push rod and needle guard are by the injection mo(u)lding of medical irradiation resistant polypropylene material.
Described packaging bag is by the polyester composite blow molding.
This utility model adopts the polyester compound film packing without dialyzing paper owing to adopted medical radiotolerant polypropylene to be used for the preparation of overcoat, push rod and needle guard.Sterilization method adopts high-energy electron beam irradiation to sterilize.Against existing technologies, this utility model can carry out irradiation sterilization with high-power electron beam, and the product colour behind the irradiation is non-yellowing, and physical and mechanical properties does not descend; Adopt high-energy electron accelerator to sterilize, have short, pollution-free, the energy-conservation advantage of sterilising cycle; Adopt the polyester compound film packaging material that do not contain dialyzing paper, the not saturating bacterium of packaging material, the holding time is long.
Description of drawings
Below in conjunction with accompanying drawing this utility model is described further.
Fig. 1 is structural representation of the present utility model.
Label among the figure is: 1. entry needle, 2. piston, 3. overcoat, 4. push rod, 5. needle guard.
The specific embodiment
As can be seen from Figure 1, the aseptic syringe of anti-irradiation of the disposable use of this utility model comprises overcoat 3, push rod 4, piston 2 and with the entry needle 1 of needle guard 5, overcoat 3 open rearward end are used for installing push rod 4, piston 2 etc.; Front end is provided with entry needle 1 connector, and tight fit or spiral cooperate installs entry needle 1.Piston 2 is installed in push rod 4 front portions, is slidingly matched with overcoat 3 inwalls, can drive in overcoat 3 mobile by push rod 4.Needle guard 5 is arranged on the entry needle outside, is used for protecting entry needle.This utility model characteristics are that described overcoat 3, push rod 4 and needle guard 5 all are by the injection mo(u)lding of medical irradiation resistant polypropylene material.
The aseptic anti-irradiation syringe exterior of the disposable use of this utility model also is provided with a packaging bag, and described packaging bag is by the polyester composite blow molding.
This utility model is owing to overcoat 3, and push rod 4, needle guard 5 adopt radiotolerant polypropylene for medical article preparation, and packaging bag is by the polyester composite blow molding.Employing is without the polyester compound film packing of dialyzing paper, and sterilization method adopts high-energy electron beam irradiation to sterilize.Sterilize with high-power electron beam, thus the contaminated environment that the ethylene oxide sterilizing of having forgone exists, the potential dangers such as carcinogenic, nervous system damage that may residual oxirane cause.
This utility model adopts the high-energy electron accelerator sterilization, do not need to resolve, and the not saturating bacterium of packaging material, the holding time is long.Can avoid conventional chemical method (oxirane) sterilization to have the shortcoming of potential hazard to the pollution of atmosphere, to medical personnel and patient, has thorough, pollution-free, the noresidue of sterilization, the advantages such as the holding time is long are a kind of safe, simple, nontoxic, syringes that the holding time is long.
Claims (2)
1. aseptic syringe of anti-irradiation of disposable use comprises overcoat, push rod, piston and with entry needle, the packaging bag of needle guard, it is characterized in that described overcoat, push rod and needle guard are by the injection mo(u)lding of medical irradiation resistant polypropylene material.
2. the aseptic syringe of anti-irradiation of disposable use according to claim 1 is characterized in that described packaging bag is by the polyester composite blow molding.
