Description

Technical Field

[0001] The utility model relates to the technical field of laboratory instruments, in particular to an experiment group counting stamp. Background Art

[0002] Mice are often used as experimental animals in animal research. However, if the animals in an experiment are of the same strain and have essentially identical biological characteristics, they cannot be identified without numbering, and the experiment cannot proceed. Therefore, grouping and labeling laboratory mice is an indispensable step in experimental research. It allows for effective tracking and differentiation of mice in different experimental groups, allows for observation of responses in different groups, facilitates data recording and analysis, and ensures the accuracy and reliability of experimental results.

[0003] There are many labeling methods currently used in experiments, such as ear tagging and ear piercing. However, these methods can cause damage to the experimental mice, potentially leading to wound infection, and unclear grouping due to damage to the ear tag or ear piercing. Staining methods are simple to operate, easy to identify, and do not cause damage or pain to the experimental animals, making them the most commonly used and easiest labeling method. However, in actual testing, the number of experimental samples is often very large. If the number of labels is performed using traditional dyeing or writing methods, a large amount of time is wasted by the experimenter, and errors are very likely to occur during the writing process. In addition, staining methods are only suitable for animals with white fur, such as strains with light fur such as ICR and BALB / C. However, C57BL / 6 mice, which are commonly used in cardiac experiments, are black or brown and are not suitable for this purpose. The dye may also fade on its own when the experiment is prolonged. The colored spots may also become lighter or even disappear due to factors such as licking, rubbing, molting, urine, and water soaking of the fur by the experimental animals. Utility Model Content

[0024] The following specific embodiments will further illustrate the present invention in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0025] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below with reference to the accompanying drawings. The drawings illustrate several embodiments of the present invention. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and comprehensive understanding of the present invention.

[0026] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended only to describe specific embodiments and are not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] See also Figures 1 to 4 The experimental group counting stamp of the present invention comprises a housing 10, a printing wheel 20 and a dye box 30. There are multiple printing wheels 20, which are rotatably arranged in the housing 10 and arranged side by side. The peripheral surface of the printing wheel 20 has multiple character molds 21 arranged at intervals.

[0029] The lower end of the housing 10 is opened to expose the character mold 21 on the printing wheel 20;

[0030] The dye box 30 is fitted at the lower end of the housing 10 . An ink pad 31 for dyeing the character mold 21 is provided in the dye box 30 . The ink soaked in the ink pad is acrylic ink.

[0031] By using multiple printing wheels 20, experimenters can quickly number and mark a large number of mice, greatly saving the time required for traditional writing methods. Specifically, each time a mouse is marked, the experimenter can turn the printing wheel 20 to adjust the font 21, change the number of one of the numbers, and then mark the next mouse. The operation is simple and convenient, and can effectively avoid typos or number confusion.

[0032] See Figure 2 and Figure 3 The housing 10 is a rectangular frame with a first fixed shaft 40 fixed therein. The plurality of printing wheels 20 are rotatably mounted on the first fixed shaft 40, and the plurality of printing wheels 20 can rotate independently. During use, the experimenter can adjust the printing number by moving any of the printing wheels 20.

[0033] In this embodiment, four printing wheels 20 are rotatably mounted on the first fixed shaft 40. The characters 21 on one of the printing wheels 20 are alphabetic characters, numbered A through J, and the characters 21 on the remaining three printing wheels 20 are numerical characters, numbered 0 through 9. Specifically, the printing wheel 20 with the alphabetic characters is located on the far left and represents the experimental group, while the last three numerical characters represent the individual mouse number. By turning the printing wheel 20, any combination of letters and numbers can be created, such as A000, B001, and so on. This allows for easy management of experimental information about the mice, such as date of birth, genotype, and experimental group, by numbering, making it easier to query and manage mouse information.

[0034] It should be noted that, in this embodiment, the ink used to impregnate the ink pad 31 is preferably acrylic ink, which has rich and bright colors, strong covering power, and long-lasting color retention. It is very suitable for marking mice with darker colors and can also meet the grouping requirements of long-term experiments.

[0035] Furthermore, in order to overcome the problem that the ink is easily stained by the fingers when the printing wheel 20 is directly moved, the present embodiment makes the following improvements to the seal. Figure 2 and Figure 3 Each printing wheel 20 is fixedly provided with a driven ring gear 51 on one side. Two fixed plates 52 are symmetrically mounted on the upper end of the housing 10. A second fixed shaft 53 is fixedly connected between the two fixed plates 52. A driving gear 54 is rotatably mounted on the second fixed shaft 53 and meshes with the driven ring gear 51. Each driving gear 54 can rotate independently. When the experimenter needs to adjust the serial number, they can turn the corresponding driving gear 54. The driving gear 54 meshes with the driven ring gear 51 to rotate the corresponding printing wheel 20. This process does not require direct contact with the printing wheel 20, effectively preventing the problem of fingers directly touching the printing wheel 20 and easily getting ink contaminated.

[0036] See Figure 4 A connecting plate 61 is provided on the inner side of the driven gear ring 51, and a fixing hole 62 is provided on the connecting plate 61. A threaded hole 63 aligned with the fixing hole 62 is provided on the side of the printing wheel 20. The fixing hole 62 is used to insert a screw 64 to connect the threaded hole 63, thereby fixing the driven gear ring 51 to the side of the printing wheel 20.

[0037] For further information, see Figures 2 to 4 The peripheral surface of the printing wheel 20 is further provided with a plurality of insertion holes 71, each located between two adjacent molds 21. The housing 10 is provided with a positioning guide sleeve 72, through which a latch 73 is inserted. One end of the latch 73 extends into the insertion hole 71, thereby limiting and fixing the printing wheel 20. It will be appreciated that when the mold 21 is in contact with the ink pad 31 or the mouse skin, the latch 73 inserted into the insertion hole 71 on the printing wheel 20 can limit the position of the printing wheel 20, preventing it from unnecessary deflection. This ensures that the mold 21 maintains a stable posture during each marking process, thereby ensuring the clarity and consistency of the numbering.

[0038] Furthermore, the tail end of the latch 73 is provided with an end cap 74, and a spring 75 is connected between the end cap 74 and the positioning guide sleeve 72. It is understood that the addition of the spring 75 allows the latch 73 to remain inserted into the socket 71 of the printing wheel 20 when no external force is applied, preventing the latch 73 from accidentally retreating and causing the locking mechanism on the printing wheel 20 to fail. At the same time, the presence of the spring 75 also provides a certain degree of convenience for the insertion and removal of the latch 73. When the printing wheel 20 needs to be rotated to adjust the number, the experimenter can overcome the tension of the spring 75 and pull the latch 73 out of the socket 71. After completing the adjustment of the printing wheel 20, the experimenter can release the latch 73, and the latch 73 will automatically reset under the action of the spring 75 and insert into the new socket 71, achieving fast and reliable fixation.

[0039] See Figure 2 The upper end of the housing 10 is provided with a sealing cover 81. The sealing cover 81 has an opening 82 for avoiding the driving gear 54 and an arc-shaped plate 83 for avoiding the second fixed shaft 53. The sealing cover 81 is used to seal the upper end of the housing 10 to prevent ink on the surface of the printing wheel 20 from splashing outward when the printing wheel 20 rotates.

[0040] Furthermore, the outer wall of the housing 10 is provided with a limiting edge 90, which abuts against the upper end of the dye cartridge 30. This limiting edge 90 is used to limit the insertion depth of the housing 10 into the dye cartridge 30, ensuring that the mold 21 is exposed to an appropriate amount of ink during the inking process, preventing unclear numbering due to insufficient ink and waste or contamination due to excessive ink.

[0041] In summary, the experimental group counting stamp in the above-mentioned embodiment of the present invention, through the use of multiple printing wheels 20, allows researchers to quickly number and mark a large number of mice, significantly reducing the time required by traditional handwriting methods. Specifically, each time a mouse is marked, the researcher can turn the printing wheel 20 to adjust the font 21, change the number of one number, and then mark the next mouse. This simple and convenient operation effectively avoids typos and number confusion. Furthermore, the acrylic ink used in the ink pad has a distinct coloring effect, with bright colors, strong coverage, and long-lasting color that is not easily faded. This makes it ideal for marking darker mice and can also meet the grouping needs of long-term experiments.
