[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0020] There are still many problems in collecting fresh cell samples from protected animals. Taking giant pandas as an example, tissue samples obtained from dead individuals may have low cell viability and microbial contamination. If invasive sampling is performed on tissues such as skin, the giant pandas will be anesthetized, requiring procedures such as fasting beforehand, transportation after anesthesia, and observation after awakening. The process is complicated and carries the risk of wound infection, which can easily cause discomfort and injury to the giant pandas.

[0021] Figure 1 This is a schematic diagram of the sampler in an embodiment of the present invention.

[0022] According to one embodiment of the present invention, a sampler is proposed, such as... Figure 1 As shown, it includes: baffle 4, telescopic rod 3 and mouth-opening device 2.

[0023] like Figure 1 As shown, the baffle 4 is provided with a hole 5; the telescopic rod 3 is adapted to extend from the hole 5 of the baffle 4, and the extended end of the telescopic rod 3 is adapted to fix the pharyngeal swab 1; the mouth-opening induction device 2 includes a container installed above the hole of the baffle 4, the container is adapted to place an inducer to induce the animal to raise its head and open its mouth to swallow the container.

[0024] According to embodiments of this invention, the animals include zoo animals that may pose a danger during sampling, such as giant pandas, monkeys, lions, tigers, and bears. The lure in the container can be varied depending on the type of animal. The following description uses a giant panda as an example to illustrate embodiments of this invention.

[0025] According to an embodiment of this invention, sampling personnel can use an inducer placed in a container to induce the giant panda to open its mouth, and then use a pharyngeal swab 1 fixed on a telescopic rod 3 to scrape the panda's oral cavity. The sampler provided by this invention can efficiently and non-invasively obtain fresh oral tissue from giant pandas while they are awake, significantly simplifying the oral sample collection process. It requires minimal cooperation from the giant panda, allowing sample collection to be completed with simple induction, avoiding anesthesia and invasive sampling, reducing discomfort and injury to the pandas, and ensuring animal welfare. Simultaneously, it simplifies the complex process of obtaining oral cells, reduces the difficulty of sampling and the safety risks to sampling personnel, greatly simplifying the cell collection process for giant pandas, ensuring the freshness of oral cell samples, and improving the success rate of cell extraction and culture preservation, providing a reference for the construction of giant panda genetic resource banks and cell resource banks.

[0026] According to embodiments of the present invention, such as Figure 1 As shown, multiple magnets 7 can be installed on the baffle 4 to fix the sampler to the railing. For example, two magnets 7 can be installed on each side of the baffle 4 so that the baffle can be firmly attached to the railing of the giant panda enclosure, making it convenient for sampling personnel to control, and also convenient to remove and move.

[0027] According to an embodiment of this utility model, a baffle 4 is used to fix the telescopic rod 3 and the mouth-opening induction device 2. The baffle 4 is a one-way transparent glass plate facing the side where the mouth-opening induction device is located. The sampling personnel can observe the giant panda's state through this glass plate from their side, but cannot see the sampling personnel from the giant panda's side. This one-way transparent glass plate makes it easy for the sampling personnel to observe the giant panda's state through the baffle 4, while preventing the giant panda from being startled and moving away from the enclosure. Furthermore, the glass plate is relatively sturdy, which also prevents the giant panda from accidentally ingesting the baffle 4 or injuring the sampling personnel. In some examples, the thickness of the baffle can be 2-8mm, the width 30-40cm, and the height 20-30cm. It can be provided with holes 5 for placing the telescopic rod 3. The holes 5 can be, for example, circular (with a diameter of 4cm or 5cm), elongated, etc. A circular shape allows for convenient and precise positioning, while an elongated shape allows for flexible adjustment of the telescopic rod 3 by moving it up and down to adapt to different positions of the giant panda's mouth. The mouth-opening induction device 2 is also fixed on the baffle.

[0028] According to embodiments of the present invention, such as Figure 1 As shown, the mouth-opening induction device 2 includes a container installed directly above the baffle opening 5. This container is used to place an inducing agent to attract the giant panda's head and open its mouth to swallow the container. This allows the sampling personnel to easily insert the end of the telescopic rod 3 into the sampling area inside the giant panda's mouth, and then use the pharyngeal swab 1 fixed to the telescopic rod 3 to scrape the panda's oral cavity. The container is fixed using any of the following methods: snap-fit, adhesive fixation, or slot fixation. In some examples, the container is 5-13 cm wide, just enough to pass through the gaps between the enclosure fences, facilitating the induction of the giant panda; the container is 10-15 cm long and 5-8 cm high. In some examples, the container is made of a transparent and sturdy material, such as a 4-6 mm thick transparent acrylic sheet, transparent plastic sheet, or other hard, transparent material that is not easily damaged. The inducing agent placed in the container can be a chopped apple, carrot, or a steamed bun coated with honey. In some embodiments, the container surface has multiple small holes for emitting scents, which can attract the giant panda's attention and guide its behavior to facilitate oral tissue sampling.

[0029] According to embodiments of this utility model, the telescopic rod 3 is selected from any one of hard materials that are not easily damaged, such as stainless steel and acrylic. Using a hard material ensures the support strength of the telescopic rod 3, prevents bending, and facilitates precise scraping of the panda's mouth. The telescopic rod 3 has a diameter of 1-2 cm, with a gap at the extended end for inserting the pharyngeal swab 1 and securing it with tape or a bandage to prevent it from easily falling out. A handle 6 is provided at the other end for easy gripping and precise operation. In some examples, the telescopic rod 3 is selected from any one of sliding telescopic, pneumatic / hydraulic telescopic, or elastic telescopic methods. Specifically, a sliding telescopic rod may include an inner tube and an outer tube sliding outside the inner tube. A through hole is provided on the outer tube, and a limiting hole adapted to the through hole can be provided on the side wall of the inner tube. When the limiting hole aligns with the through hole, the length of the telescopic rod is fixed by sequentially inserting a limiting member into the through hole and the limiting hole.

[0030] According to an embodiment of this utility model, specifically, in actual operation, such as Figure 1 As shown, the sampler is fixed to the railing by magnet 7, and the mouth-opening device 2 is inserted into the gap of the railing. The panda is induced to open its mouth by the mouth-opening device 2 on the sampler. After the panda opens its mouth, the telescopic rod 3 with the pharyngeal swab 1 is extended out of the hole 5 on the sampler baffle 4 and inserted into the panda's mouth. The pharyngeal swab is quickly scraped from the panda's mouth by the handle 6 on the telescopic rod 3.

[0031] According to an embodiment of this invention, the baffle 4 acts as a physical barrier, and in conjunction with the extension operation of the telescopic rod 3, maintains a safe distance, reducing direct contact between sampling personnel and giant pandas. The integrated design of the sampler combines the induction, positioning, and sampling processes, improving operational efficiency. Using the method of this invention, oral tissue from giant pandas can be collected simply and efficiently, minimizing interference with the pandas' normal lives while ensuring the safety of sampling personnel.
