Technical field
The utility model belongs to the mechanical testing instrument field, is specifically related to a kind of biological tissue's anchor clamps of organizing the adhesion material adhesion for test organisms.
Background technology
Biological tissue's adhesion material mainly is the macromolecular material for biologic adhesion preparation and sealer field.Wherein biologic adhesion preparation has the characteristic of certain affinity to biological mucosa by some macromolecular material, with these polymer substances as pharmaceutical carrier, make preparation have the preparation technique of location, sustained release performance, and biological sealer refers to that biodegradable film class or glue family macromolecule material adhesion are to the wound of tissue, avoid wound to be subjected to outside the infection, prevent effectively organize blood oozing from the wound surface and veinlet hemorrhage, seal defective tissue, promote wound healing, prevent tissue adhesion.Therefore biological tissue's adhesion material most important with the testing in vitro biological tissue adhesion in above-mentioned field.
Be used at present the metering mechanism that test organisms is organized the device of adhesion material adhesion mainly to comprise the pedestal of biological tissue's anchor clamps, the adhesion material sample plummer relative with biological tissue anchor clamps, secure attachment material sample plummer and applied variable force to biological tissue's anchor clamps, the power that pedestal and metering mechanism apply is opposite, increase the power that applies along with metering mechanism, make the biological tissue section and the adhesion material sample separation that adhere to each other, during by separation, the power that metering mechanism applies can calculate the size of adhesion.
But biological tissue section is to be attached to fully on the anchor clamps by seccotine at present, makes that biological tissue is difficult for fixing because tissue contains tissue fluid, causes the failure of an experiment.And because artificial sample preparation can't guarantee that the shape and size of biological tissue section are unified, will cause the poor repeatability of experimental data like this, the comparison difficulty.
The utility model content
Technical problem to be solved in the utility model is the fixedly geomery disunities of shakiness and biological tissue section of existing biological tissue anchor clamps, cause test data inaccurate, in order to overcome above deficiency, a kind of biological tissue's anchor clamps of organizing the adhesion material adhesion for test organisms are provided.
In order to solve the problems of the technologies described above, the technical solution of the utility model is: describedly organize biological tissue's anchor clamps of adhesion material adhesion to comprise train wheel bridge and lower plate for test organisms, described train wheel bridge comprises the upper mounted plate of fixedlying connected with lower plate and the plummer of upper mounted plate protrusions, described lower plate comprise with the fixedly connected bottom plate of upper mounted plate and bottom plate in the through hole that matches with plummer.The center section of biological tissue section overlays on the plummer, plummer passes through hole, the marginal portion of biological tissue section is clamped in fixedly connected upper mounted plate and bottom plate between train wheel bridge and the lower plate, biological tissue section is fixed between train wheel bridge and the lower plate, is overlying on the size and dimension of biological tissue section of carrier-table surface by relative fixed.
Further, described upper mounted plate is fixedlyed connected by fixture with bottom plate, and described fixture is magnet or threaded connector.
Further, described upper mounted plate is provided with fixed orifice, and described bottom plate is provided with and last fixed orifice lower fixed hole one to one, and last fixed orifice and lower fixed hole are used for arranging fixture.
Further, describedly organize biological tissue's anchor clamps of adhesion material adhesion to comprise a lower plate that above clear size of opening is different for test organisms.Cross the unitarity that pine or tension can not influence final detection result because be fixed between train wheel bridge and lower plate biological tissue section, so the different-thickness biological tissue section needs the lower plate of different clear size of opening to cooperate with plummer.
Further, describedly organize the material of biological tissue's anchor clamps of adhesion material adhesion to be selected from lightweight stainless steel, vitallium, titanium alloy, polypropylene or tygon for test organisms, above-mentioned material density is less to be suitable for making this small and exquisite testing tool, and often contact with biological fluid in the test, above-mentioned material is corrosion-resistant, easy to clean, is difficult for contaminated.
Can carry out series of tests at the different biological tissue's anchor clamps of many group plummer sizes during test, for reducing test error.
The technical scheme that the utility model provides can be effective, permanent fixing various biological tissue sections, guarantee the surfacing of biological tissue.Because the size and dimension of plummer is fixed, so the contact area of each biological tissue and adhesion material sample is fixed, and reduced the error in the experiment measuring process, and the process of biological tissue clamped is simple, be convenient to operation, improved conventional efficient greatly.
