The device realizes fixed to album fungus appearance syringe needle, and the syringe needle need not be handed to the right hand in aseptic testing process, avoids the syringe needle to puncture aseptic gloves, reduces the potential safety hazard, and singlehanded handheld sample can be relaxed and filtered low in labor strength, easy operation on the insertion needle in addition.
Description
Technical field
This utility model relates to technical field of medical instruments, is specifically related to a kind of germ collector needle fixture.
Background technology
The method that pharmaceuticals steriling test generally uses at present is that the membrane filter that will be equipped with filter membrane is connected with exhaust pump, pneumatics is utilized to carry out measuring samples filtering collection bacterium, the microorganism-collectings such as antibacterial that sample is contained within, fungus are on filter membrane, then it is transferred to filter membrane in culture medium cultivate, whether last sample survey has bacterium, has the most also engendered that the germ collector utilizing above-mentioned principle design to manufacture is for sterile collection and inspection.As Chinese patent CN2393886Y discloses a kind of germ collector, but the germ collector of the disclosure is similar with presently commercially available traditional germ collector, when steriling test, left hand is needed to hold sample, the right hand holds the syringe needle of bacteria gathering filter, carry out the filtration of sample, after syringe needle inserts sample, also need to hang on germ collector by sample, often change a sample, needs insert the needle into once, sample is linked into once, after sucking filtration terminates, need from germ collector, take off sample, syringe needle is extracted, carry out the sucking filtration of next bottle of sample, in whole checkout procedure, the sterile gloves that both hands are worn easily is punctured by syringe needle, while making operator come to harm, also detection sample can be made to be contaminated.Therefore, germ collector syringe needle is fixed and the improvement of mode of operation, become the problem needing solution at present badly.
Summary of the invention
In order to overcome the defect of prior art, the purpose of this utility model is to provide a kind of germ collector needle fixture, and this device realizes fixing syringe needle, it is repeatedly inserted into without hand-held needle and extracts operation, avoiding syringe needle to puncture sterile gloves, labor intensity is low, reduces processing cost and potential safety hazard.
In order to realize object above, this utility model adopts the following technical scheme that
A kind of germ collector needle fixture, including base, described base is provided with hollow support post, and the upper end of described hollow support post is provided with the bracing frame for supporting sample bottle；The lower end of support frame as described above is provided with the opening connected with hollow support post；It is provided with, on the sidewall of described hollow support post, the annular groove setting fixed needle base for card；Described annular groove top edge distance hollow support post distance topmost is less than the length of syringe needle；Being provided with the strip opening of the short transverse extension along hollow support post on the sidewall of described hollow support post, described strip opening upwards extends to the upper end of bracing frame, extends downward less than annular groove.
The external diameter of described annular groove is equal to the external diameter of needle mount, and the height of described annular groove is equal to the height of needle mount.
It is provided with the pin hole for interpolation fixing pin on the sidewall of the upper end hollow support post of described annular groove.
Described pin hole is two pin holes symmetrical relative to strip opening.
Open Side Down extends to the lower end of hollow support post for described strip.
Support frame as described above is that upper end open is more than the tubaeform of lower ending opening, and the upper end of support frame as described above has circumferentially around the sidewall extended.
This utility model germ collector needle fixture, during use, needle mount is inserted in annular groove from strip opening part, and card sets and is fixed at annular groove, syringe needle respiratory organ is exposed at the outside of hollow support post along strip opening, drug liquid tube stretches out from opening part, owing to annular groove top edge distance hollow support post height topmost is less than the length of syringe needle, syringe needle is made to protrude upward hollow support post, making syringe needle may be inserted into sample bottle, it is stable that the bracing frame simultaneously arranged can support again sample bottle.In a word, this utility model germ collector needle fixture, it is achieved syringe needle is fixed, during Sterility testing, the right hand is without hand-held needle, avoid syringe needle to puncture sterile gloves, reduce potential safety hazard, and single-hand held sample can be easily inserted on syringe needle and filter, filtration terminates rear one hand and can easily choose empty bottle, labor intensity is low, and processing cost is low, simple to operate, and this fixing device can move in opereating specification, the area that takes up room is little.
Further, this utility model germ collector needle fixture, is provided with the pin hole for interpolation fixing pin on the upper end hollow support post of annular groove, the further fixed needle base of insertion of pin, avoid needle holder to remove draw-in groove during plug sample bottle, improve the stability of syringe needle.

Fig. 2 is the overall structure schematic diagram that the germ collector needle fixture that this reality new embodiment provides installs syringe needle and sample bottle.
Detailed description of the invention
Embodiment
The present embodiment germ collector needle fixture, as depicted in figs. 1 and 2, including base 9, described base 9 is provided with hollow support post 7, and the upper end of described hollow support post 7 is provided with the bracing frame 2 for supporting sample bottle 1；The lower end of support frame as described above 2 is provided with the opening connected with hollow support post；The annular groove 5 setting fixed needle base 10 for card it is provided with on the sidewall of described hollow support post；Described annular groove top edge distance hollow support post height topmost is less than the length of syringe needle 3；Being provided with the strip opening 8 of the short transverse extension along hollow support post on the sidewall of described hollow support post, described strip opening 8 extends upwardly to the upper end of bracing frame, extends downward the lower end of hollow support post.Drug liquid tube 6 stretches out from opening part.
Support frame as described above is that upper end open is more than the tubaeform of lower ending opening, and the upper end of support frame as described above has circumferentially around the sidewall extended.The shape of support frame as described above does not have decisive role to the serviceability of this utility model germ collector needle fixture, and therefore this bracing frame can also be other shapes.
In order to improve the fixing device fixation to syringe needle further, the external diameter of described annular groove is equal to the external diameter of needle mount, and the height of described annular groove is equal to the height of needle mount.
In order to further improve the fixing device fixation to syringe needle, the sidewall of the upper end hollow support post of described annular groove being provided with the pin hole 4 for interpolation fixing pin, described pin hole is two pin holes symmetrical relative to strip opening.
