Description
Technical Field
The invention relates to the technical field of bio-related industries, in particular to a handheld tail marker suitable for rodents.
Background
In animal experiments, numbering of animals is an essential step to ensure that the experiments are carried out smoothly. The labeling method which is stable, clear and rapid and can be preserved for a long time not only ensures the identifiability of each experimental animal, but also reduces the workload of experimenters and avoids the influence of multiple numbering on animal behaviors.
The current common marking methods are mainly divided into two methods, one method is to mark on a cage box where animals live, and the marking method is only suitable for animals raised in a single cage, so the efficiency is low; the other method is to directly mark the animal body, and the method mainly comprises the following steps: dyeing marks, hole cutting, branding, ear tags, tail tattooing and the like. The dyeing marking method generally refers to marking on the fur or tail of an animal by using a special dye or a marker pen, although the marking method is simple and convenient to operate, the marking method is only suitable for short-term animal experiments, because the marks are blurred or even disappear due to the hair combing and licking behaviors of the animal and friction between the animal and padding and a cage wall, and the marks are easily covered by the fur of the animal and are not easy to identify by experimenters. Furthermore, the number of animals marked by this labeling method is too small and is not suitable for species with black fur such as C57 BL. The mark can be marked for a long time by cutting holes, branding and ear marks, but has large trauma to animals and does not meet the welfare requirement of the animals. In addition, the methods are time-consuming and low in efficiency, and the experimental personnel are easily scratched and bitten in the operation process. The existing equipment is complex to operate and inconvenient to move, and part of the existing equipment needs to be bound by a binding device to the animals, so that the efficiency is low. In addition, the mark may be blurred or disappear as the animals age, or fighting between animals, healing of the mark wound, and biting by the animals. In conclusion, the marking method has the problems that the operation is inconvenient, the injury is easily caused to experimenters and experimental animals, the animal numbers are difficult to store for a long time, and the number information is easily lost.
In summary, the existing various experimental animal numbering methods have certain disadvantages, such as tedious operation, long time consumption, low labeling efficiency, and a narrow application range, and no technology or device capable of overcoming the defects exists at present, and the labeling can be stably, clearly, quickly, harmfully, and can be stored for a long time. Based on this, we have designed a hand-held tail marker suitable for rodents.

the spine part is of a conical structure, the handheld tail marking instrument further comprises a placing table 2, a support 3 is fixedly arranged on one side of the upper surface of the placing table 2, and a U-shaped support matched with the marking instrument body in shape and size is arranged at the top end of the support 3; the end part of the placing table at one side of the bracket is also fixedly connected with a fixed seat 1, a storage box 15 is arranged in the fixed seat, and the top end of the fixed seat is respectively provided with a cleaning box 4 and an ink box 16;
the tail limiting block 13 is provided with a plurality of models according to the size difference of the tail of the experimental animal; the man-machine interaction device is provided with an experimental animal selection button, an ink absorption mode button, a cleaning mode button and an experimental animal label information input module.
The use principle of the invention is as follows:
when the invention is used, as shown in fig. 1 and 2, the marking instrument body is taken down from the bracket 3, then the outer side end of the cylinder body is aligned with the upper port of the ink box 16, wherein, the ink box and the cleaning box are preferably soaked with ink or clear water by using sponge, after the ink box is aligned, the ink absorption mode is selected by the man-machine interaction device, then the controller start button 7 is started, under the control of the preset program, the sharp part of the marking needle extends out of the outer side end of the cylinder body completely, is soaked into the ink box, and stores ink by the needle groove 003. After the ink is absorbed, the experimental animal to be marked is selected through an experimental animal selection button of the human-computer interaction device, and the number to be marked is input through an experimental animal marking information input module. Then, an experimenter holds the handle, screws the tail limiting block 13 of the corresponding model at the outer end of the barrel body, takes out the experimental animal, controls the experimental animal on the hard table top, presses the tail of the experimental animal through the arc limiting groove 18 on the tail limiting block 13, and properly adjusts the position of the arc limiting groove 18 to enable the tail to be in a state of being attached to the arc limiting groove 18; the controller start button 7 is pressed, and under the control of a preset program, the marking needle is enabled to mark numbers on the tail of the experimental animal in a mode of controlling the marking needle driving mechanism.
In the process of marking numbers, taking a marking needle as an example, as shown in fig. 5 and 6, when the marking needle performs a marking operation, the controller starts the second electromagnetic valve 011, high-pressure gas in the pressure gas chamber 05 flows into the connecting pipe 09 from the gas supply pipe 010, then flows into the guide pipe 06, pushes the piston 061 to move outwards, the piston drives the connecting rod 062 and the connecting rod drives the sliding block 063 and the sliding block drives the marking needle 001, so that the sharp part passes through the strip-shaped through hole 19 to enter the arc-shaped limiting groove 18, a tapered hole is pierced on the tail of the experimental animal, and ink flows into the tapered hole through the needle groove to complete marking of the point. As described above, according to the preset program, the controller sequentially activates the marking pins at the plurality of positions to mark, and finally forms the animal mark number as shown in fig. 9.
As shown in fig. 9, the animal mark number is formed by a plurality of line segments 0002, the line segments intersect to form an intersection 0001, and the number of marking points of the line segments formed between the end points 0003 of the line segments and the intersection 0001 and between the intersection and the intersection cannot be less than three, so that the line segments and the gaps 0004 are distinguished from each other, and the confusion between the line segments and the gaps is avoided.
The high-pressure gas source pipe 9 of the invention needs to be connected with a high-pressure gas supply device, the pressure in the pressure gas bin is detected in real time through the pressure sensor 04, and when the gas pressure is insufficient, the first electromagnetic valve is opened in time for inflation; similarly, when the marking motion of the marking needle is finished, the third electromagnetic valve is opened, the air is released through the air release pipe, and the marking needle can be restored to the original position due to the elastic force of the return spring.
As shown in figure 2, when the label needs to be cleaned after the label is finished, the tail limiting block 13 needs to be taken down, the outer side end of the barrel body is aligned to the upper end of the clean water box, then the cleaning mode is selected through the man-machine interaction device, and under the control of a preset program, the sharp-pricked part of the label needle repeatedly extends into the clean water of the cleaning box, so that the label needle is cleaned.
After cleaning, as shown in fig. 1 and 2, the gun body of the marking instrument body is clamped on the U-shaped support of the bracket 3, the bottom end of the handle is propped against the table surface of the placing table, and the cover of the cleaning box and the ink box is covered.
