Description
Technical Field
The utility model belongs to the technical field of the medical treatment, concretely relates to animal brain tissue fills and sample acquires laboratory bench.
Background
In the research of animal brain functions, brain structures and brain diseases, the method has important effects on perfusing brain tissues and then slicing the brain tissues to observe tissue structures, physiological and pathological characteristics of the brain tissues and the like, and is an important means for the research of the brain. Generally, when brain tissue is fixed and a sample is obtained, brain blood needs to be firstly perfused to be clean by buffer solution such as PBS (phosphate buffer solution) and the like, then the brain tissue is fixed by formalin perfusion, finally, the cranium of an animal is cut off by the neck, and then the cranium is opened to take out the brain tissue. The animal is usually placed to the animal board and is fixed when prior art pours into, then open the thorax, pour into through the aorta, and flow out the perfusate through the superior vena cava, pour into PBS buffer solution earlier, with the blood lavage of cranium clean, then pour into formalin, cut off the cranium at last, then split the cranium from the face of animal, prior art is inconvenient when pouring the waste liquid of collecting among the perfusion process, when cutting off the back skull with animal cranium, because animal (often with rat or mouse) cranium is less, be difficult for fixing during the cutting, so the cranium often rolls during the cutting, often the accidental injury operating personnel.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve the weak point among the prior art, provide an animal brain tissue fills and sample acquires the laboratory bench, use this laboratory bench can conveniently collect the waste liquid, fixed animal head is firm steady, makes things convenient for the operator to carry out cutting operation.
In order to solve the technical problem, the utility model adopts the following technical scheme: the animal brain tissue perfusion and sample acquisition experiment table comprises an experiment table, a cavity is arranged in the experiment table, the right side of the experiment table is open, a waste liquid collection drawer is arranged at the opening at the right side of the experiment table, a transparent cover is hinged to the left side of the experiment table, a flange is arranged around the table top of the experiment table, a plurality of water leakage holes are uniformly distributed on the table top of the experiment table, fixing columns are fixed at four corners of the table top of the experiment table, each fixing column is connected with a tether, a head positioning groove is formed in the front of the table top of the experiment table, two mounting grooves are formed in the experiment table, the two mounting grooves are positioned on the left side and the right side of the head positioning groove, a positioning fixture block is slidably connected to each mounting groove, opposite surfaces of the two positioning fixture blocks are of cambered surface structures, a compression spring;
the experiment table is also provided with a cutter, the cutter is positioned behind the head positioning groove, and one end of the cutter is hinged on the table surface of the experiment table.
Adopt above-mentioned technical scheme, the utility model discloses following beneficial effect has: in the whole experiment process, the waste liquid on the table top of the experiment table flows into the waste liquid collecting drawer below through the water leakage hole, so that the waste liquid is convenient to clean, and the head of the animal is fixed by utilizing the two positioning fixture blocks, so that the head of the animal is prevented from rolling to accidentally injure operators when the neck of the animal is cut; the whole structure is reasonable in design and convenient to use.

Detailed Description
As shown in figure 1, the animal brain tissue perfusion and specimen acquisition experiment table of the utility model comprises an experiment table 1, a cavity is arranged in the experiment table 1, the right side of the experiment table 1 is open, a waste liquid collection drawer 2 is arranged at the opening of the right side of the experiment table 1, a transparent cover 3 is hinged at the left side of the experiment table 1, a flange 4 is arranged around the table surface of the experiment table 1, a plurality of water leakage holes 5 are evenly distributed on the table surface of the experiment table 1, fixed columns 6 are fixed at the four corners of the table surface of the experiment table 1, a tether 7 is connected on each fixed column 6, a head positioning groove 8 is arranged at the front part of the table surface of the experiment table 1, two mounting grooves are arranged on the experiment table 1, the two mounting grooves are positioned at the left side and the right side of the head positioning groove 8, a positioning fixture block 9 is connected on each mounting groove in a, two ends of the compression spring 10 are respectively in abutting fit with the positioning fixture block 9 and the groove wall of the mounting groove;
the experiment table 1 is further provided with a cutter 11, the cutter 11 is located behind the head positioning groove 8, and one end of the cutter 11 is hinged to the table surface of the experiment table 1.
When the animal brain tissue perfusion and sample acquisition experiments are carried out, the animal is anesthetized firstly, four limbs are fixed on four fixing columns 6 by using tethers 7, the head of the animal is positioned in a head positioning groove 8, then the head of the animal is clamped by two positioning clamping blocks 9 under the action of a compression spring 10, then the thoracic cavity is opened, the perfusion liquid flows out through the aorta, then PBS buffer solution is filled, the blood of the head and the cranium is cleaned, then formalin solution is filled, the neck of the animal is cut off by using a cutter 11 after the perfusion is finished, then the incision is started from the face, the brain tissue is taken out, in the whole experiment process, the waste liquid on the table top of the experiment table 1 flows into a waste liquid collecting drawer 2 below through a water leakage hole 5, the waste liquid is convenient to clean, the head of the animal is fixed by using the two positioning clamping blocks 9, the animal is prevented from being, the cranium rolls to injure the operator by mistake.
The present embodiment is not intended to limit the shape, material, structure, etc. of the present invention in any form, and all of the technical matters of the present invention belong to the protection scope of the present invention to any simple modification, equivalent change and modification made by the above embodiments.
