Description
Technical field
This utility model relates to a kind of novel rat fixing device.
Background technology
Rat and mouse is Rodents minitype animal experiment conventional in basic medical experimental teaching and scientific research, and its breeding is fast, by standardization cultivate can be a large amount of production.The basic research of disease and the preclinical test research of new drug is widely used in because having many pathologies similar with human diseases.
In disease incidence Mechanism Study and materia medica research field, need sometimes to carry out continuous print blood sampling at different time points to animal, by the time taken a blood sample sacrifice of animal just for the last time.This continuous print Blood collection of fixing time is that researcher provides abundant biological specimen, by the tracking and monitoring to index of correlation in different blood sample, contribute to researcher and be better familiar with the dynamic change of some important biomolecule marks in disease development and prognosis process thereof, contribute to exploitation relevant clinical diagnostic kit; In pharmacokinetic, detected the change of the rat associated target substance in the blood sample of different time points after administration by instrument analytical method, contribute to the details that researcher grasps medicine process in vivo, for the research and development of medicine provide experiment basis.
In experiment, the blood-sampling method of rat and mouse has orbital venous plexus blood sampling, disconnected (cutting) tail blood sampling, ventral aorta blood sampling, Culling heart blood and broken end to take a blood sample, and the method being suitable for taking a blood sample continuously at body is orbital venous plexus blood sampling and disconnected (cutting) tail blood collection method.Conventional rat body weight is generally at about 200-400g, and because rat build is comparatively large, strength is also large, will be grabbed steady and repeatedly take a blood sample not easy to operate, may enrage rat and blood sampling person be stung hemorrhage under the prerequisite of not anaesthetizing.Therefore, build be applicable to rat and mouse experimental teaching and scientific research, simple and feasible fixing blood-taking device is necessary.
Utility model content
For problems of the prior art, the purpose of this utility model is the technical scheme providing a kind of novel rat fixing device.
Described a kind of novel rat fixing device, it is characterized in that comprising platen, platen central authorities are provided with the groove of rat ventral health of can fitting, platen one end arranges the jut being used for fixing rat tail, jut arranges elastic threads, and the end of elastic threads connects one section for being socketed the soft tube of rat tail; The side of described platen is fixedly installed one piece of wrap, and wrap at least can be wound around platen two circle; Described wrap circumference is provided with rubber band, and the free end of wrap arranges VELCRO.

In figure: 1-platen, 2-jut, 3-elastic threads, 4-soft tube, 5-wrap, 6-set bolt, 7-rubber band, 8-groove, 9-arcuate groove, 10-rat, 11-tail.
Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail:
A kind of novel rat fixing device, comprise platen 1, platen 1 central authorities are provided with the groove 8 of rat ventral health of can fitting, groove 8 size can be arranged according to rat body, platen 1 one end arranges the outwardly part 2 being used for fixing rat tail, jut 2 arranged outside has arcuate groove 9, be beneficial to fixing rat tail, jut arranges elastic threads 3, the end of elastic threads 3 connects one section for being socketed the soft tube 4 of rat tail, when rat is fixed on after on platen 1, its tail 11 is fixed through soft tube 4; The side of platen 1 is fixedly installed one piece of wrap 5, the size of wrap 5 and the size of rat 10 adapt, set bolt 6 or other modes can be adopted to be fixed on platen 1, wrap 5 at least can be wound around platen two circle, wrap 5 circumference is provided with rubber band 7, the free end of wrap 6 arranges VELCRO, ensures that parcel is tight.This utility model can be convenient, flexible realize fixedly securing of the rat and mouse of different size, for orbital venous plexus and tail vein blood provide safe and effective approach.
Rat fixing device of the present utility model also can be scaled, is fixed mice.
Platen of the present utility model is rectangle sheet material, there are the groove of rat ventral health of can fitting in platen central authorities, can hold extremity and the veutro of rat, the wrap of a sufficient length is fixed in the side of platen by set bolt, with wrap multi-lay winding rat or mice with fixing; By the silicon case casing that is connected in the elastic threads tail base rat or mice, its tail base is fixed on the ledge of platen, makes the fixing more firm of rat or mice; Wrap to wrap the rat be placed on platen, the extremity of mice and trunk, in " cylinder " shape, is convenient to the blood sampling of follow-up different approaches for multi-lay winding; Elastic threads one end is connected to the jut of platen, and the other end connects soft tube, and its tail passes after fixing rat, mice, and is fixed on platen by elastic threads by soft tube; Rat, mice is placed at the groove of platen central authorities, and in the mode that the winding of multilamellar wrap, afterbody are fixed, and rat, mice head are exposed.Such fixed form makes rat present " cylinder " shape and cannot move, and being convenient to researcher carries out tail vein blood and tail vein injection administration; Researcher only needs two ears capturing rat, mice, and side eyeball is given prominence to, and can facilitate and carry out orbital venous plexus blood sampling safely.
Platen of the present utility model can be different material, and the size and dimension of the length of platen, width and platen drop-center can according to the size adjusting of rat, mice, to adapt to rat, the mice of different size; Wrap can be different material, and the length of wrap and width can according to the size adjusting of rat, mice, to adapt to rat, the mice of different size; The soft tube of fixing tail can be different material, and the internal diameter of flexible pipe can adjust according to the tail thickness of rat, mice, to adapt to rat, the mice of different size; The elastic threads connecting soft tube can be different material; The fixing fixed form of wrap on platen can be the various fixed forms comprising set bolt.
This utility model embodies hommization set-up mode, and wrap is soft can allow rat feel comfortable, and multilamellar wrap is wound around then to embody and supple and hard with solidness in softnessly fixedly secures effect, and is conducive to researcher and captures more easily.Platen is rectangle sheet material, and there are the groove of rat ventral health of can fitting in platen central authorities, and wrap is fixed on platen by set bolt by the side of platen.By catching the skin between rat two ear and ears to be placed on platen drop-center by rat with front lying position, rapidly wrap being wrapped in rat and firmly fixing to obtain to stablize with it, be i.e. " cylinder " shape; After fixing, by the silicon case casing that is connected in elastic threads at rat tail root, rat tail root is fixed on the arcuate groove of outwardly part of platen, makes the fixing more firm of rat.
Under above-mentioned rat is fixed and is flat on the state on table (as shown in Figure 3), quick shearing part tail, the mode of smoothing out with the fingers tail tip from rat tail root by three fingers takes tail vein sample.Because rat to be fixed on platen in " cylinder " shape by multilamellar wrap, the generation of the situations such as the struggle of rat, twisting therefore can be avoided in blood collection procedure; In like manner, after rat is fixing by said apparatus, then catch the skin between the ears of rat and ears, side eyes keep opening and eyeball are given prominence to, and with blood capillary corner of the eyes inserting needle within the eye, gather eyeground vein clump blood; We can also carry out tail vein injection administration to fixing rat.
Finally, it is also to be noted that what enumerate above is only a specific embodiment of the present utility model.Obviously, content described by this utility model is not limited to above embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive from content disclosed in this utility model or associate, all should think protection domain of the present utility model.
