Description
Technical Field
The application relates to the technical field of life science and medical health, in particular to an animal conveying device and an animal behavioristics experiment system.
Background
The model animals have the characteristics of convenient material taking, short generation, more offspring, clear genetic background, thorough understanding of life phenomena, easy experimental operation and the like, and have very high scientific reference value. Therefore, model animals play a very important role in experimental studies in the fields of life sciences and medical health. Among them, animal behavior research is also an extremely important circle, which interpenetrates animal behavior with many other branches in life sciences and medicine such as genetics, molecular biology, cell biology, neuroscience, etc., links animal behavior phenotype with genotype, molecular cellular mechanism, and neural loop mechanism, and further elaborates life mechanism completely and systematically from different perspectives.
In addition, animal disease models are mainly used for experimental physiology, experimental pathology and experimental therapeutics (including new drug screening) studies. The development of human diseases is very complicated, and researchers have difficulty in taking human beings as experimental objects to deeply discuss the disease occurrence mechanism. In addition, the experience of clinical accumulation is limited not only in time and space, but also in practicality and methodological limitations in many experiments. By establishing an animal disease model and observing animal behaviors similar to human disease symptoms, researchers can consciously change factors which cannot be or are not easy to eliminate under natural conditions so as to more accurately observe experimental results of the model and perform comparative research on the experimental results and the human diseases, and the method is helpful for more conveniently and effectively understanding occurrence and development rules of the human diseases and researching prevention and treatment measures. Therefore, animal behavior is an important index for studying pathology and evaluating therapeutic measures.
Currently, during the course of a behavioral experiment, the step of "transporting the experimental small animal into the experimental apparatus" is generally carried out manually, without the aid of machines, so as to enhance the anxiety of the experimental small animal. Taking a mouse as an example, the laboratory operator typically pinches the tail of the mouse with the thumb and forefinger to transport the mouse from the feeding cage into the laboratory apparatus, which causes the mouse to become stressed and anxious, thereby affecting the results of the experiment. In addition, it is possible for the laboratory operator to be bitten by the mouse. Therefore, the experimental operator should use the proper experimental small animal transfer method to make the transfer process as possible without touching the experimental small animal, and even to be automatic, so as to maintain the experimental small animal in a normal emotional state as possible, and not to influence the experimental result.

The appearances of the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.
Referring to fig. 1 and 2, fig. 1 is a first state structure diagram of a first embodiment of the animal transfer device provided in the present application, and fig. 2 is a second state structure diagram of the first embodiment of the animal transfer device provided in the present application, and the animal transfer device 100 includes a transfer passage 10, a waiting room 20, and a transfer room 30.
Wherein the transfer passage 10 includes a passage inlet 10a and a passage outlet 10b, wherein the waiting chamber 20 is disposed corresponding to the passage inlet 10 a. Alternatively, the waiting chamber 20 is provided at a side thereof with an opening 20a, and the opening 20a corresponds to the channel entrance 10 a. Alternatively, the shape of the transfer passage 10, the shape of the passage inlet 10a and the shape of the passage outlet 10b may be arbitrarily set according to the requirement, for example, the transfer passage 10 may be a cylinder, a rectangular cylinder, or the like, and the shape of the passage inlet 10a and the passage outlet 10b may be a circle, a rectangle.
It will be appreciated that the holding chamber 20 is used for holding animals, the number of animals may be one or more, and means for providing drinking water or food may be provided in the holding chamber 20 so that the animals held therein may be eaten. Alternatively, the top of the waiting room 20 may be open or provided with other "doors" for entry and exit of animals so that the laboratory personnel can put in and take out the animals.
Further, the transfer chamber 30 is disposed in the transfer passage 10 to be movable along the transfer passage 10 between the passage inlet 10a and the passage outlet 10b, and the transfer chamber 30 is in communication with the waiting chamber 20 while staying at the corresponding passage inlet 10 a.
Specifically, the transfer chamber 30 is provided with a first opening 30a and a second opening 30b, as shown in fig. 1, the first opening 30a communicates with the passage inlet 10a when the transfer chamber 30 is moved to the passage inlet 10 a; as shown in fig. 2, when the transfer chamber 30 moves to the passage outlet 10b, the second opening 30b communicates with the passage outlet 10 b.
In addition, the animal transfer device 100 includes a sensor 40 for detecting the presence of an animal in the transfer chamber 30.
In one embodiment, the sensor 40 may be a pressure sensor disposed at the bottom of the transfer chamber 30 for detecting whether an animal is present in the transfer chamber 30 by detecting the pressure applied. For example, when the transfer chamber 30 is "empty," the weight is X, i.e., the pressure generated by the pressure sensor is X, and when an animal is present therein, the weight is X + Y. In one embodiment, to prevent false detection, it can be determined whether Y is greater than a set threshold, wherein the selection of Y can be set according to the smaller of the detected animals, and when Y is determined to be greater than the set threshold, it is determined that there is an animal in the transfer chamber 30.
In other embodiments, sensors may be provided inside the transfer chamber 30 to detect. For example, an infrared sensor may be provided to detect whether a moving object is present inside the transfer chamber 30, or a camera may be provided to capture an image of the inside of the transfer chamber 30, and further an image recognition process may be provided to detect whether an animal is present inside the transfer chamber 30.
Optionally, in one embodiment, the animal transporter 100 further comprises a lift 50 and a controller (not shown) disposed within the transport path 10, the lift 50 being connected to the controller and the transport chamber 30 for driving the transport chamber 30 to move between the path entrance 10a and the path exit 10b under the control of the controller.

1. placing at least one animal in a waiting room 20;
2. controlling the transfer chamber 30 to move to the passage entrance 10a such that the opening 20a of the waiting chamber 20, the passage entrance 10a, and the first opening 30a communicate (or in an initial state, the transfer chamber 30 stays at the passage entrance 10a by default);
3. since laboratory small animals have freely exploratory behavior, they will spontaneously enter the transfer chamber 30, and it is noted that, in general, only one animal will be studied behaviorally at a time, and therefore the space of the transfer chamber 30 can be set to accommodate only one animal;
with continued reference to FIG. 2:
4. the sensor 40 sends a signal to the controller when it detects an animal in the transport chamber 30, the controller further controlling the elevator to move the transport chamber 30 from the tunnel entrance 10a to the tunnel exit 10 b; it is noted that, since the first opening 30a and the second opening 30b of the transfer chamber 30 are generally not provided with blocking means such as "gates", the size of the transfer chamber 30 may be slightly smaller than the inner diameter of the transfer passage 10 in order to avoid animals from coming out of the transfer chamber 30 during movement;
5. when the transferring chamber 30 moves to the passage outlet 10b, the second opening 30b of the transferring chamber 30 communicates with the passage outlet 10b, and the experimental small animals spontaneously come out from the transferring chamber 30 because they have a freely exploratory behavior.
It will be appreciated that in this embodiment the transfer channel 10 is arranged in a vertical manner to transfer the animal from a high position to a low position. In other embodiments, the conveying channel 10 can also be arranged transversely from the lower position to the upper position, and the description is omitted here.
Unlike the prior art, this embodiment provides an animal transfer device comprising: a waiting room for placing animals; the conveying channel comprises a channel inlet and a channel outlet, wherein the waiting chamber is arranged corresponding to the channel inlet; a transfer chamber disposed in the transfer passage and movable along the transfer passage between the passage inlet and the passage outlet, the transfer chamber being communicated with the waiting chamber while staying at the corresponding passage inlet; a sensor for detecting the presence of an animal in the transfer chamber; a controller coupled to the sensor and the transport chamber for controlling the transport chamber to move from the entrance to the exit of the tunnel upon detecting an animal in the transport chamber. Through the mode, the experimental toy is conveyed without touching the animal and approaching the animal, so that the experimental toy is conveyed in sequence in a one-way mode to enter the experimental device for behavioural analysis, the behavioural analysis can be performed more efficiently, and the phenomena of animal anxiety, experimental operator bite and the like in the process of manually conveying the experimental toy are avoided.
Referring to fig. 3, fig. 3 is a schematic diagram of a first state structure of a second embodiment of the animal transfer device provided in the present application, and the animal transfer device 100 includes a transfer passage 10, a waiting room 20, and a transfer room 30.
The transfer passage 10, the waiting chamber 20, and the transfer chamber 30 are similar to those of the above-described embodiment, and will not be described again.
In this embodiment, the animal transfer device 100 further comprises a blocking mechanism 60 for blocking the entrance 10a of the passageway when the transfer chamber 30 is remote from the entrance 10a of the passageway.
Further, an inwardly facing protrusion 70 is provided inside the channel between the channel inlet 10a and the channel outlet 10 b.
Referring to fig. 4, fig. 4 is a schematic structural view of the blocking mechanism 60 in fig. 3, wherein the blocking mechanism 60 includes a fixing plate 61 and a baffle plate 62, and the fixing plate 61 is disposed on a side of the transfer chamber 30 away from the channel outlet 10 b; the baffle plate 62 is connected to the fixed plate 61.
Alternatively, the blocking mechanism 60 may be configured to resemble a "chair," with the fixed plate 61 corresponding to the "seat plate" of the "chair" and the blocking plate 62 corresponding to the "back plate" of the "chair". Wherein, the baffle plate 62 and the fixing plate 61 can be arranged at an angle of approximately 90 deg.
With continued reference to fig. 5, fig. 5 is a second state of the animal transfer device of the second embodiment provided herein.
Wherein the fixing plate 61 and the blocking plate 62 move together with the transfer chamber when the transfer chamber 30 moves toward the passage outlet, and the blocking plate 62 blocks the passage inlet 10a when the fixing plate 61 is caught by the protrusion 70.
It will be understood that the distance between the protrusions 70 at both sides of the inside of the transfer passage 10 is smaller than the width of the fixing plate 61, and therefore, the fixing plate 61 is caught on the protrusions 70 during the lowering of the transfer chamber 30, so that the blocking plate 62 just blocks the passage entrance 10 a. Wherein the shape of the baffle plate 62 may be set according to the shape of the passage inlet 10 a.
Optionally, the lower side surface of the fixing plate 61 can be further provided with fixing columns corresponding to the two protrusions 70 on the two sides, and the distance between the outer sides of the two fixing columns is smaller than the distance between the two protrusions 70, so that the two fixing columns are clamped between the two protrusions, and the blocking mechanism 60 is prevented from moving left and right integrally.
Referring to fig. 6 and 7, fig. 6 is a first state structure diagram of a third embodiment of the animal transfer device provided in the present application, and fig. 7 is a second state structure diagram of the third embodiment of the animal transfer device provided in the present application, wherein the animal transfer device 100 includes a transfer passage 10, a waiting room 20 and a transfer room 30.
The transfer passage 10, the waiting chamber 20, and the transfer chamber 30 are similar to those of the above-described embodiment, and will not be described again.
In this embodiment, the animal transfer device 100 further comprises an advancing mechanism 80 for advancing from the first opening 30a to push the animal in the transfer chamber 30 out of the second opening 30b and the tunnel outlet 10b while the transfer chamber 30 is resting on the tunnel outlet 10 b.
Specifically, the other side of the transfer passage 10 corresponding to the passage outlet 11b is provided with a push-in port 10c so that the push-in mechanism 80 is inserted from the push-in port 10c and is pushed in from the first opening 30a to push the animal in the transfer chamber 30 out from the second opening 30b and the passage outlet 10 b.
Alternatively, in one embodiment, the propulsion mechanism 80 may be propelled in a manual manner. For example, when the transfer chamber 30 remains at the tunnel exit 10b, in one case the animal may voluntarily exit the tunnel exit 10b, and in another case the animal may be manually propelled by the propulsion mechanism 80 if it does not exit for a period of time.
Alternatively, in another embodiment, the propulsion mechanism 80 may be controlled by a controller. For example, the controller controls the operation of the elevator and the propulsion mechanism 80 synchronously, and when the elevator is controlled to drive the transfer chamber 30 to the passage outlet 10b, the propulsion mechanism 80 is controlled to extend from the propulsion port 10c and further to propel from the first opening 30a to push the animal in the transfer chamber 30 out from the second opening 30b and the passage outlet 10 b. At other times, the control and propulsion mechanism 80 is located outside the transfer tunnel 10.

In addition, medical absorbent cotton may be provided in the transfer chamber 30, the waiting chamber 20, the slope 90, and the like.
Optionally, a ramp 90 may also be provided at the passage outlet 10b to allow the animal in the transfer chamber 30 to exit the transfer chamber through the ramp 90.
In addition, the embodiment of the present application further provides an animal behavioristics experimental system, the animal behavioristics experimental system includes the animal conveying device and the behavioristics experimental device provided in the above embodiments, and an inlet of the behavioristics experimental device is arranged corresponding to the channel outlet 10b of the animal conveying device 100, so that the animal coming out from the channel outlet 10b enters the behavioristics experimental device to perform behavioristics experiments.
The following description will be made by combining the above embodiments of fig. 3 to 7:
referring to fig. 3:
1. placing at least one animal in a waiting room 20;
2. controlling the transfer chamber 30 to move to the passage entrance 10a such that the opening 20a of the waiting chamber 20, the passage entrance 10a, and the first opening 30a communicate (or in an initial state, the transfer chamber 30 stays at the passage entrance 10a by default);
at this time, the blocking mechanism 60 is located above the transfer chamber 30;
referring to fig. 6, the pushing mechanism 80 is located outside the conveying channel 10;
3. since laboratory small animals have freely exploratory behavior, they will spontaneously enter the transfer chamber 30, and it is noted that, in general, only one animal will be studied behaviorally at a time, and therefore the space of the transfer chamber 30 can be set to accommodate only one animal;
with continued reference to FIG. 5:
4. the sensor 40 sends a signal to the controller when it detects an animal in the transport chamber 30, the controller further controlling the elevator to move the transport chamber 30 from the tunnel entrance 10a to the tunnel exit 10 b; it is noted that, since the first opening 30a and the second opening 30b of the transfer chamber 30 are generally not provided with blocking means such as "gates", the size of the transfer chamber 30 may be slightly smaller than the inner diameter of the transfer passage 10 in order to avoid animals from coming out of the transfer chamber 30 during movement;
at this time, the fixing plate 61 of the blocking mechanism 60 is clamped between the protrusions 70, and the baffle plate 62 of the blocking mechanism 60 blocks the channel inlet 10 a;
5. when the transfer chamber 30 moves to the passage outlet 10b, the second opening 30b of the transfer chamber 30 and the passage outlet 10b communicate;
