Description
Technical field
The present invention relates to the rotatable liquids of animals infusion device of a kind of 360 degree, be used in laboratory environment, carrying out the scientific experiments of aspects such as biological nutrition, clinical pharmacy, belong to medical science and medical scientific research animal experiment technique at the experiment meiofauna.
Background technology
In a large amount of life medical researchs, medicine research and development and production process, laboratory animal is crucial subjects.But how to simulate the animal nature living environment under different experimental conditions; make tested animal under arm's length basis metabolism condition, be engaged in related science research; meet the laboratory animal welfare simultaneously; follow laboratory animal ethics; and the experimental data that provides true, accurate for this reason, meets scientific law, be the common hopes of pursuing of numerous researchers.Laboratory animal is in the experiment condition and lab space of regulation, by it being provided metastable feed, drinking-water, rest, drainage activity space, simulated animal nature life habit as far as possible, Animal nutrition absorbs to obtain meeting, the experimental data of pathology evolution process under the normal physiological processes of energy metabolism or the disease conditions.
Traditional animal infusion set generally all is that infusion set and acceptor are non-coaxial two parts, can not link simultaneously.And existing animal experiment method carries out the liquid infusion experiment of the outer nutrition of relevant enteral and other biological metabolism aspect normally under the condition to tested animal row general anesthesia or pressure Baoding, and therefore the deficiency of following several respects is arranged:
(1) under static conditions, tested animal is because of being anaesthetized or being whipped, and its basal metabolic rate descends, and the energy metabolism activity reduces, so that organism physiology, biochemical many relevant parameters change, and are difficult to tested animal life activity and the active real conditions of nutrient metabolism under the simulating natural condition.
(2) the liquid infusion device owing to can not do the circumference rotation, will inevitably make the connection flexible pipe be distorted, roll over flat distortion because of the activity of animal subject, so that liquid can not normally be input in the body of animal subject as being other soft methods of attachment of non-coaxial rotation.
(3) being suitable for relevant experimentation is limited in scope.
(4) be forced to Baoding as animal subject, must cause the abnormal change of this animal aspect spirit and behavior, even cause the body wound of the non-empirical factor of animal subject, also do not meet the ethical spirit of love laboratory animal and kind treatment laboratory animal.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, provide a kind of 360 degree rotatable liquids of animals infusion device, can carry out the liquid infusion experiment of vein or other histoorgan and not be subjected to the influence of arbitrary motion laboratory animal, for laboratory animal provides one can keep the autonomic activities ability, the laboratory environment of free relatively activity space is arranged.
For realizing such purpose, in the rotatable liquids of animals infusion device of 360 degree of the present invention's design, form coaxial linkage structure by multiduty runing rest, rotatable central shaft with holes and flexible rustless steel tube for transfusion, runing rest is with the central shaft disjunctor rotatable with holes that is fixed in the ball-bearing housing, the bearing block fixed flat planar is connected by bolt with the infusion device fixed flat planar, and the infusion device fixed flat planar is fixed on the laboratory animal cage tool.The transfusion silica gel tube passes the endoporus and the flexible rustless steel tube for transfusion of rotatable central shaft with holes, links to each other with tube chamber such as animal subject vein/digestive tube.Under the effect that contains the oil seal ball bearing, infusion device can be portable be made the autonomic movement of any direction with animal subject in experimental cage, and liquid is carried and is not affected.
