[0002] Animal models are indispensable tools in biomedical research. In experiments to study salivary gland diseases, it is usually necessary to collect saliva from the salivary glands of experimental animals. Mice are commonly used animals for animal experiments. The current process of collecting mouse saliva is to use elastic rubber bands to tie the mouse's limbs to a board with nails at the four corners, then hang the rubber bands on the mouse's upper teeth, lift the rubber bands upward to lift the mouse's head to keep the mouth open, and then use a pipette to reach into the mouse's mouth to extract saliva. This method requires the mouse's limbs to be tied and fixed after anesthesia. Otherwise, it is easy for the mouse to struggle and cause difficulty in tying and fixing. There is also a risk of the mouse biting the experimenter, and it is easy to cause harm to the mouse itself. Summary of the invention
[0003] The utility model aims to provide a mouse saliva collector to solve the problems existing in the prior art, so as to avoid the problem that mice bite experimenters and cause harm to the mice themselves.

[0033] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0034] In the description of the present invention, it should be noted that the directions or positional relationships indicated by terms such as "middle", "upper", "lower", "left", "right", "inside" and "outside" are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.
[0035] like Figure 1 As shown, the specific scheme of the embodiment is as follows: a mouse saliva collector includes a mouse temporary storage box 1, a top opening 4 is opened on the top of the mouse temporary storage box 1, and also includes a gate 2 inserted from the top of the mouse temporary storage box 1, an observation port is opened at one end of the mouse temporary storage box 1 away from the gate 2, and an observation window 3 is bonded to the inner wall of the observation port.
[0036] It should be noted here that the observation port is located at the upper part of the mouse temporary storage box 1, which is higher than the mouse, and the mouse temporary storage box 1 itself is opaque. When the mouse is locked in the mouse temporary storage box 1, the inside of the mouse temporary storage box 1 is not in a dark environment because the observation window 3 and the top port 4 can transmit light, but the mouse cannot see the researcher standing outside the mouse temporary storage box 1. This can reduce the range of the researcher exposed to the mouse's line of sight, so as to a certain extent, the mouse can be lowered earlier, and then it is convenient to lure the mouse.
[0037] The researcher can observe the state of the mouse at any time through the observation window 3 and timely grasp the timing of taking out the saliva collection capsule 7 to reduce the time that the mouse saliva stays in the outside world, thereby ensuring the purity of the mouse saliva as much as possible.
[0038] See also Figure 1-6In this embodiment, an aroma dispersing component 5 filled with scented bait for emitting aroma to attract mice is provided on the top of the mouse temporary storage box 1. An air guide duct 6 is provided on one side of the aroma dispersing component 5 and extends through the top opening 4 to the inside of the mouse temporary storage box 1 for transporting aroma. The air guide duct 6 includes a conduit 61 movably connected to the aroma dispersing component 5 and a clamping tube 63 arranged at the lower end of the conduit 61. A saliva collecting bag 7 is provided on the inner side of the clamping tube 63 for inducing mice to actively gnaw and leave saliva. The saliva collecting bag 7 includes an inner skeleton 71 and a cotton bag 72 wrapped on the surface of the inner skeleton 71.
[0039] After the mice are locked in the mouse temporary storage box 1, fragrant bait is put into the fragrance distributing component 5, and the fragrance enters the saliva collecting capsule 7 through the air guide pipe 6, so that the saliva collecting capsule 7 emits fragrance in the mouse temporary storage box 1 to lure the mice, making them unable to resist gnawing on the saliva collecting capsule 7. During the gnawing process, the saliva in the mouse's mouth will remain on the cotton bag 72. After the researchers disassemble the air guide pipe 6 and the fragrance distributing component 5, the saliva collecting capsule 7 stained with the mouse's saliva can be taken out from the top opening 4, and then the saliva collecting capsule 7 is removed from the clamp tube 63 and put into a test tube filled with reagents to complete the collection of the mouse's saliva. The whole process uses the method of inducement to make the mice actively leave saliva, which will not only not cause harm to the mice, but also will not make the mice resist, and it is convenient to repeatedly extract the mouse's saliva.
[0040] See also Figure 1 The aroma dissemination component 5 includes a storage box 51 fixed on the top surface of the mouse temporary storage box 1, the storage box 51 is filled with fragrant bait, and the top of the storage box 51 is provided with a top cover 52. The fragrant bait is selected from the favorite food of mice and can be directly put in from the top of the storage box 51.
[0041] The aroma dispersing assembly 5 further comprises a wind tube 53 arranged on the side wall of the storage box 51, the wind tube 53 is connected with the storage box 51, and a small fan is arranged inside the wind tube 53. The wind tube 53 is used to fill the storage box 51 with air to accelerate the speed of the scent of the bait to be dispersed.
[0042] The fragrance dispensing assembly 5 further includes a three-pronged pipe 54 connected to the storage box 51 . The three-pronged pipe 54 includes an air outlet pipe 541 connected to the storage box 51 and a bifurcated pipe 542 connected to the other end of the air outlet pipe 541 .
[0043] The wind force of the air tube 53 is dispersed through the bifurcated tube 542 to reduce the wind force, allowing the scented air to enter the saliva collection bag 7 more naturally.
[0044] The top end of the catheter 61 is sleeved with one end of the bifurcated tube 542 through a butt joint 62. The butt joint 62 allows researchers to disassemble the catheter 61 and the bifurcated tube 542 more easily.
[0045] Please refer to 4-5, the clamp tube 63 is a C-shaped elastic plastic tube, the lower end of the catheter 61 is connected to the middle of the clamp tube 63, and both ends of the clamp tube 63 are fixedly installed with plug plates 64 inserted into the saliva collection bag 7.
[0046] By using a C-shaped elastic plastic tube, the saliva collecting bag 7 can be clamped by the elastic force of the clamping tube 63 itself, which is convenient for installing the saliva collecting bag 7 and also convenient for removing the saliva collecting bag 7.
[0047] The inserting plate 64 is a hollow “convex” plate, the outer diameter of the inserting plate 64 is larger than the inner diameters of the two ends of the saliva collecting bag 7 , and the clamping tube 63 is connected to the saliva collecting bag 7 through the inserting plate 64 .
[0048] The inserting plates 64 are inserted into the two ends of the saliva collecting bag 7 to make the connection between the saliva collecting bag 7 and the clamping tube 63 more stable.
[0049] See also Figure 5-6 The saliva collecting bag 7 is a hollow columnar body with thin ends and thick middle, and a plurality of ventilation holes are provided on the surface of the cotton bag 72. The thin ends and thick middle saliva collecting bag 7 make it easier for mice to get saliva on them when they gnaw on them. At the same time, the ventilation holes provide convenience for fragrance to be emitted from the inside of the saliva collecting bag 7.
[0050] Working principle: Put the scented bait into the storage box 51, and the fragrance emitted by the scented bait is introduced into the catheter 61 through the air duct 53, and then enters the saliva collecting capsule 7, so that the saliva collecting capsule 7 emits fragrance in the mouse temporary storage box 1, thereby luring the mice and making them unable to help but gnaw on the saliva collecting capsule 7. During the gnawing process of the mice, the saliva in the mouth of the mice will remain on the cotton bag 72. After the researchers disassemble the air guide duct 6 and the fragrance dispensing component 5, the saliva collecting capsule 7 stained with the mouse saliva is taken out from the top opening 4, and then the saliva collecting capsule 7 is removed from the clamp tube 63 and put into a test tube filled with reagents. That is, the collection of mouse saliva can be completed without any harm to the mice themselves and without the mice biting the researchers.
