Technical Field

The invention relates to the technical field of animal experiment devices, in particular to a multifunctional experiment operating platform suitable for rodents.

Background

In animal experiments, blood or serum of animals is a very common detection material, and the collection of the blood of the animals is the basic skill which needs to be mastered by each experimenter performing the animal experiments. In addition, the quality and volume of the collected blood have great influence on the next step of the experiment, which not only depends on the skill level of the experimenter, but also depends on the times of blood collection and the blood collection method; the current commonly used blood sampling methods for animals include: the method comprises the following steps of submaxillary vein blood collection, tail (tip) clipping blood collection, tail vein blood collection, eyeball picking blood collection, orbital venous plexus blood collection, heart blood collection, carotid artery and venous blood collection, femoral artery (venous) blood collection, abdominal aorta blood collection and the like. Improper restraint can cause an animal to struggle in the blood drawing process, so that the pain of the animal is increased, the welfare standard of the animal is not met, the internal organs and nerves of the animal are easily injured by the blood drawing needle due to struggling of the animal, and the data of the animal is wasted due to serious disability of the experimental animal; the death of the experimental animals is directly caused by the serious condition, and the whole experiment is influenced. In addition, in the process, the animal blood is easy to contact with dirt, so that the blood sample is hemolyzed and cannot be detected; in addition, struggle of the animal can cause blood to splash on the experiment table, lead to the reduction of sample volume and sample quality, and the clearance after the experiment is ended of being not convenient for.

In addition, in the traditional Chinese medicine acupuncture research, acupuncture stimulation is often performed on an animal model to observe the curative effect; because of the particularity of acupuncture therapy, anesthesia can not be carried out on animals generally, but the prior experimental devices such as a binding barrel and the like can not fix the experimental animals well, and acupuncture points of partial abdomen and limbs are bound by the binding device, so that acupuncture and moxibustion can not be carried out; the animal can be held by an assistant or fixed acupuncture can be performed on the animal by using a self-made device (such as an adhesive tape and a chest strap for pets). The method is complex to operate, consumes a large amount of manpower and material resources, cannot well fix the animal, and struggles the experimental animal to cause deviation of acupuncture positions or fall of acupuncture needles (particularly electric needles), thereby greatly influencing experimental results; in addition, it is easy to bite or scratch the experimenter.

On the basis of the above embodiment, the present embodiment is further modified as follows:

as shown in fig. 3, a diversion trench 31 is further arranged on the upper surface of the movable platform around the animal blood taking part, and one end of the diversion trench 31 penetrates through the end part of the movable platform;

as shown in fig. 5, the edge of the fixing platform is further provided with a plurality of test tube locking holes 36, and the test tube locking holes located on one side of the fixing platform facing the output end of the diversion trench are used in cooperation with the diversion trench 31.

In this embodiment, when the animal blood sampling, the accessible is pressed touch-sensitive screen control panel's relevant button and is made the certain angle of fly leaf slope, makes blood directly flow into the downthehole test tube of test tube card through the guiding gutter to simplify the blood sampling procedure, reduced the blood sampling degree of difficulty.

Examples 9,

On the basis of the above embodiment, the present embodiment is further modified as follows:

as shown in fig. 1 and 2, a plurality of observation holes 24 are uniformly distributed on the lower part of the side wall of the binding bin, although the binding bin can be made into a semitransparent shape, in order to not disturb animals, the binding bin can be made into a non-transparent shape, and the ventilation and the observation of the positions of the animals can be facilitated through the observation holes.

The working principle of the invention is as follows:

laboratory animal can select upset movable platform or direct blood sampling according to the kind of blood sampling after being tied, behind the upset movable platform, should take off the magnetism suction disc, and the belly that the hole will laboratory animal is exposed this moment presents, conveniently takes a blood sample operation.

When the experimental animals after the constraint and with the film cladding are taken a blood sample, can not take place the animal and tear and struggle the injury incident, also can avoid blood to be polluted by the hair simultaneously, each position of film cladding all is translucent state simultaneously, can not lead to the blood sampling position to be sheltered from because of the constraint animal to can carry out all kinds of blood samplings and acupuncture experiments.
