Abstract

The utility model relates to the technical field of pipettes, in particular to an antibacterial pipette, which comprises a plastic housing. The outer surface of the plastic housing is coated with a nanometer silver antibacterial material layer; the active ingredients of the nanometer silver antibacterial material layer formed by nanometer silver are silver ions; the silver ions are slowly released through ion exchange and can block the key function of a microorganism after being absorbed by microbial cells, so that the death of the microorganism is caused, the growth of the microorganism can be effectively restricted, and the antibacterial action is effective; and because the releasing process of the silver ions on the nano silver antibacterial material layer is slow, the surface of the nanometer silver antibacterial material layer has effective action concentration, the action time is longer, and the antibacterial effect is durable.

Description

A kind of antibiotic pipettor

Technical field:

The utility model relates to and moves the liquid Instrument technology field, particularly a kind of antibiotic pipettor.

Background technology:

In medical treatment, medicine, gene and protein research, biological study, drug development laboratory and other biological technology application, often need utilize pipettor in various laboratory operation rules, to come handle laboratory, it utilizes pipettor that the liquid of certain volume is sucked in the pipette, then liquid is distributed into one or more dispensed volume.

The various microorganisms that distributing around the people, for example bacterium, fungi and algae, thereby people's skin is easy to be stained with various microorganisms, they are not to be harmful to usually, but other apparatus of hand contamination easily by the people.Pipettor is a handheld apparatus, even the user is through strict cleaning flow process, its microorganism on hand still can pollute the case surface of pipettor, thereby influence the test result of laboratory sample, but the shell of existing pipettor does not have antibacterial functions, shell can not suppress microbial growth after being subjected to microbial contamination, influenced the result of use of pipettor.

The utility model content:

The purpose of this utility model is that a kind of antibiotic pipettor that utilizes Nano Silver to suppress growth of microorganism is provided at the deficiencies in the prior art.

For achieving the above object, the utility model adopts following technical scheme:

A kind of antibiotic pipettor, it includes plastic shell, and described plastic shell outer surface is coated with the nano silver antibacterial material layer.

Described plastic shell also can be all to be coated with the nano silver antibacterial material layer at inner surface and outer surface.

The utility model beneficial effect is: the utility model includes plastic shell, the plastic shell outer surface is coated with the nano silver antibacterial material layer, the active component of the nano silver antibacterial material layer that is made of Nano Silver is a silver ion, silver ion slowly releases by ion-exchange, can be blocked the function of microorganism key after the microbial cell absorption, thereby cause the death of microorganism, can suppress the growth of microorganism effectively, have the antibacterial action that has; And the process that the silver ion of nano silver antibacterial material layer discharges is slower, but guarantees that enough the surface of nano silver antibacterial material layer keeps effective function concentration, and action time is longer, and antibiotic effect is lasting.

Description of drawings:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is a sectional view of the present utility model;

Fig. 3 is the sectional view of another embodiment of the utility model.

The specific embodiment:

Below in conjunction with accompanying drawing the utility model is further described, see Fig. 1～2, a kind of antibiotic pipettor, it includes plastic shell 1, plastic shell 1 outer surface is coated with nano silver antibacterial material layer 2, and the active component of the nano silver antibacterial material layer 2 that is made of Nano Silver is a silver ion, Nano Silver surface reduction electromotive force height, can make surrounding air produce elemental oxygen, can play bactericidal action.The SH of Nano Silver in can strong adsorption bacterial body endoenzyme protein molecular ,-NH2 ,-genes such as COOH, and reaction has with it hindered the synthetic and energy source of protein, has destroyed the cell membrane of bacterium, causes bacterium death.After bacterium death, Nano Silver dissociates out again, contacts with other bacteriums, carries out new round sterilization activity, so once and again killing bacteria.Experiment shows, just is adsorbed with 107～108 nano-silver ionics around the killed Escherichia coli, shows that this Nano Silver all has effect to Escherichia coli, Candida albicans etc.Silver ion also can with the DNA combination in the pathogenic bacteria, the silver ion that combines with the DNA base forms cross-linked each other, causes the dna structure sex change in the germ, suppresses it and duplicates, and pathogenic bacteria are lost vigor.Silver ion can also with the skin glycan reaction that exposes on the bacteria cell wall, form the invertibity compound, make it not advance cell to oxygen transport, stop the germ activity, cause its death.Nano silver particles size in the nano silver antibacterial material layer 2 is 1～10 nanometer, is uniformly dispersed, and the production technology cost is low, and is harmless during application.

Silver ion slowly releases by ion-exchange, can block the function of microorganism key after being absorbed by microbial cell, thereby cause the death of microorganism, can suppress the growth of microorganism effectively, has the antibacterial action that has; And the process that the silver ion of nano silver antibacterial material layer 2 discharges is slower, but guarantees that enough the surface of nano silver antibacterial material layer 2 keeps effective function concentration, and action time is longer, and antibiotic effect is lasting.

See Fig. 3, as another embodiment of the present utility model, different from the embodiment described above is that plastic shell 1 is all to be coated with nano silver antibacterial material layer 2 at inner surface and outer surface, makes the inner surface of plastic shell 1 and outer surface all have antibacterial functions.

The above only is a better embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the utility model patent claim.
