[0002] Bezoar is the gallstone of the liver of cattle, a mammal of the phylum Chordata. The one produced in the gallbladder is called "bile yellow" or "egg yolk", the one produced in the bile duct is called "tube yellow", and the one produced in the liver duct is called "liver yellow". The traditional artificial bezoar is poorly formed during the manufacturing process, and the manufacturing quality of bezoar is low. Therefore, it is necessary to use the bezoar bed. The production of the bezoar bed (core) is the matrix for the formation of bezoar and is the key to the cultivation of bezoar.

[0003] The existing patent CN212186760U discloses a detachable bezoar bed, including a grid-shaped skeleton and an adsorption film, the adsorption film is arranged on the inner surface of the skeleton, the skeleton includes an upper cover, a bed body and a lower cover from top to bottom, the upper cover, the bed body and the lower cover are movably connected to each other, the upper cover, the bed body and the lower cover are all provided with matching hole partitions, and a buffer layer is provided on the side of the skeleton. The existing patent CN 221243488 U discloses an improved bezoar bed, including a bed body, the bed body is formed by a plurality of spiral strips arranged at equal intervals in a circular array, one end of the bed body is an open end, the bed body is provided with a neck ring fixedly connected to the end of the opening, and the outer surface of the neck ring is fixedly connected to an external thread; the connecting mechanism includes a cover ring arranged below the neck ring, the inner surface of the cover ring is fixedly connected to an internal thread, and the internal thread is engaged with the external thread by rotation. The existing patent CN206151893U discloses a bezoar bed, which belongs to the field of drug processing auxiliary equipment, including a cloth bag, an upper cover with a grid structure and a lower cover with a grid structure. The upper cover has a first constriction and a first opening, the lower cover has a second constriction and a second opening, the upper cover and the lower cover are detachably connected so that the first opening is docked with the second opening, and the first opening and the second opening are located between the first constriction and the second constriction; the cloth bag has at least one opening, the upper cover and the lower cover are located in the cloth bag, and the opening is located at the first constriction or the second constriction.

[0004] However, the above disclosed bezoar bed has the following defects:

[0005] ① The skeleton structure of the bezoar bed is fixed, and the overall shape cannot be changed. When implanted into the cow, the incision required is relatively large, which is not conducive to the recovery of the cow's health and has a great impact on the quality of the bezoar cultivated in the cow;

[0006] ② The overall stability of the bezoar bed with a combined connection structure is poor. When the bile inside the bed body hardens and clumps, the resulting expansion causes the connectors to loosen and fail, further causing the bezoar bed components to detach;

[0007] ③ The multi-layer structure in the bezoar bed easily causes the bile flow to be blocked and it is difficult to pass through the inside of the bezoar bed. Moreover, the collection method of bezoar is one-way collection, which will lead to a large loss of small bezoar particles and the poor quality of the cultivated bezoar. Content of the Utility Model
