Description

A kind of drug sensitive test paper distributor
Technical field
The invention belongs to medical experiment equipment manufacturing technology field, more particularly to one kind on microbiological culture media flat board Add the drug sensitive test paper distributor of drug sensitive test paper.
Background technology
Drug sensitivity test abbreviation drug sensitive test(Or resistance test), it is intended to pathogenic microorganism is understood to various antibiotic It is sensitive(Or tolerance)Degree, to instruct clinical rational to select the microbiology test of antibiotic medicine.The method of drug sensitive test is The sample containing pathogenic bacteria is taken from the infection site of patient, is seeded on appropriate culture medium, in culture under certain condition;Simultaneously By the scraps of paper containing various concentrations, variety classes antibiotic respectively(Referred to as " drug sensitive test paper ")Agar media surface is attached to, is trained Result is observed after supporting certain time.To ensure the experiment accuracy and the convenience of operation of drug sensitive test, generally large batch of , it is necessary to use drug sensitive test paper distributor in test process.It is generally this to prevent the pollution of drug sensitive test paper and being easy to storage to operate Drug sensitive test paper distributor needs to coordinate the pencil for loading drug sensitive test paper to use, and is currently used for loading the pencil profile kind of drug sensitive test paper Class is more, and presently commercially available drug sensitive test paper distributor can only be applicable one of which, it is impossible to accomplish that same drug sensitive test paper distributor is fitted A variety of pencils are used, inconvenience is so caused in use, experimentation cost is also increased.On the other hand, it is loaded with medicine The distributor of the quick scraps of paper, to ensure the activity of drug sensitive test paper, it is necessary to which specific condition is stored, condition of storage is stored in for routine use 2-8 DEG C, -20 DEG C are stored in for a long time, if the volume of so drug sensitive test paper distributor is excessive, will result in the storage after use not Just.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of drug sensitive test paper distributor, the drug sensitive test paper distributor can be same When suitable for a variety of commercially available loading drug sensitive test papers pencils, while the drug sensitive test paper distributor push rod can divide with main distributor From, reduce the volume of drug sensitive test paper distributor, be easy to storage.
To realize above-mentioned technique effect, the present invention is adopted the following technical scheme that:A kind of drug sensitive test paper distributor, including push away Bar, upper shell, internal rotating part, push part, spring, spring pedestal and moving coil.
Push rod is with upper shell to be detachably connected, and push rod includes push rod cap, push rod, attachment cap, the two ends point of push rod Push rod cap and push rod are not connected with, and wherein push rod cap is with push rod to be fixedly connected, and push rod is to be flexibly connected with attachment cap, In particular by the fixation sliding block connection on the guide groove and attachment cap in push rod;There are a connecting tube, connecting tube in upper shell center With attachment cap to be detachably connected, so as to realize the connection of upper shell and push rod.
Upper shell surface is evenly distributed with the pipeline that several can be used for holding plurality of specifications pencil, the pipeline and opened up There are 3 kinds of necks, respectively with pencil A, B(Or C), the projection on D coincide, by changing the neck shape on pipeline, make susceptibility paper Piece distributor is adapted to different pencils.One end of upper shell connecting tube is connected the other end and internal rotating part phase with push rod Even, internal rotating accessory inner surface, which is fixed with downward guide rail, moving coil, is fixed with a cylindrical boss, and guide rail front end is inserted Enter on cylindrical boss in corresponding hole.The guide rail is divided into vertical portion and rotating part, pushes internal rotating part guide rail The bootable moving coil of rotating part rotates to an angle and stopped operating after α, and the calculation formula of the anglec of rotation is as follows:
α = 360/2n(Wherein n is the quantity of pipeline on upper shell)
Spring housing is cased with moving coil outside cylindrical boss, spring housing is built with spring, the other end and the inside of the spring Rotating part is connected, and is fixed with and pushes pin and drug sensitive test paper delivery outlet around spring housing surrounding, there is height on drug sensitive test paper delivery outlet periphery Go out to move the edge of panel surface, have space between the front end and chassis pushed pin, the thickness for front end of pushing pin and the thickness of drug sensitive test paper Identical, the open bottom of B, C, D type pencil can not only be passed through by being pushed pin when using, and can also penetrate through the closed bottom end of A type pencils, Drug sensitive test paper is pushed out to drug sensitive test paper delivery outlet, drug sensitive test paper is just limited to drug sensitive test paper by drug sensitive test paper delivery outlet edge In delivery outlet.
The circular hole for having the circular hole passed through for cylindrical boss on part and supplying pipeline to pass through is pushed, part plane perpendicular is pushed It is fixed with rammer pin.There is the circular hole passed through for boss in the middle of spring pedestal, push and spring is connected between part and spring pedestal.Lower casing Several baffle plates are installed, for culture dish position limitation in distributor working range on body.Push rod is pushed by drug sensitive test paper It is pushed out in drug sensitive test paper delivery outlet, continues to push push rod, the bottom of internal rotating part is contacted with pushing accessory inner surface, under Pressure part starts to move downward, and the drug sensitive test paper that rammer pin is placed in drug sensitive test paper delivery outlet is released and is pressed on culture medium;Move Except the pressure applied on push rod, resetted in spring-return power effect lower push-rod and inner body.
Further, the connection between the lower house and push rod can be to be threadedly coupled to the present invention.
Further, be cased with adjusting on the lower house outer wall on base, the adjustment base has different depth to the present invention Neck, the limited block on neck and lower house coordinates the height of adjustable distributor.
Further, spring pedestal upper surface is fixed with two guide pillars to the present invention, and guide pillar may pass through to push and be set on part Guide hole, to ensure to push part and move along a straight line.
Further, described push is fixed with spring leaf to the present invention on part, and the other end of spring leaf is connected with ramming pin.
