The invention relates to the technical field of aquaculture and feed engineering, and discloses a bionic fish digestion simulation system based on heat pump temperature control and software driving, which comprises an environment simulation subsystem, a bionic stomach digestion subsystem, a bionic pylorus subsystem, a bionic intestinal tract subsystem and an intelligent control and detection subsystem. The whole bionic digestive organ is immersed in an extremely stable water body environment, and accurate and stable control of the water temperature of + / -0.1 DEG C of the experimental water tank is realized. The problems that a traditional method is poor in temperature uniformity and large in fluctuation are fundamentally solved, the body temperature requirements of various fishes such as cold water fishes and warm water fishes can be accurately met, a reliable temperature basis is provided for digestive enzyme activity simulation, and the scientificity and repeatability of experimental data are remarkably improved.

The invention discloses a nutrition feeding conduit which comprises an in-vivo discharging part, the in-vivo discharging part comprises a discharging piece, and the discharging piece is provided with a first channel for oil to penetrate through; the in-vitro feeding part comprises an operating part, a containing chamber with an opening in one end is formed in the operating part, and a feeding guide pipe is connected to the side face of the operating part; one end of the flexible guide pipe is connected with the discharging piece, and the other end of the flexible guide pipe is connected with a port of the containing chamber. The feeding space is separated from the food storage space, gastric acid is prevented from flowing back when food is conveyed, meanwhile, air in the feeding space can be exhausted through the arranged flexible pull rod before the food is conveyed, and the air is prevented from being conveyed to digestive organs.

The present invention provides a self-assembling peptide gel for use in preventing a leak of digestive fluid and a self-assembling peptide gel for use in protecting an organ against digestion by a digestive fluid. The self-assembling peptide gel comprises a self-assembling peptide and water, whereby the self-assembling peptide gel has an adhesion persistence ratio with respect to a collagen sheet of at least 40% and a decomposition ratio of 35% or less in pancreatic juice treatment at 37°C for 7 days, and the self-assembling peptide gel is positively charged as a whole.

This invention discloses a woven scaffold for digestive organs adapted to intestinal peristalsis and its weaving method. The scaffold is woven from several main filaments and several auxiliary filaments on a fixture with protruding pins, forming a first end, a second end, and several main body segments between the first and second ends. The main filaments are woven into the end or main body segments to form a columnar scaffold. The auxiliary filaments are wound from top to bottom around the columnar scaffold formed by the main filaments. The total number of main filaments and auxiliary filaments is not greater than the number of protruding pins in the circumferential direction of the fixture. The tail portion of the main filaments is wound parallel to the auxiliary filaments. This invention uses multiple main filaments to form a columnar scaffold, avoiding the problem of easy breakage when weaving with a single main filament. Furthermore, the use of auxiliary filaments wound around the outer circumference of the main filaments improves the radial support force of the scaffold, making it more adaptable to the variability of the intestine and extending its service life.

Provided is a determination device comprising a control unit that uses a determination model representing the relationship between vital information obtained after surgery of a digestive organ and complication information including information indicating whether or not a complication occurred within a predetermined period of time after the surgery, and determines, on the basis of the vital information obtained from a determination target person who has undergone surgery of the digestive organ, complication information indicating whether or not the determination target person develops a complication at a predetermined time after the vital information has been obtained.

The application belongs to the technical field of medical devices, and provides an endoscopic foreign body extraction and expansion device. The application comprises a pair of expansion assemblies and a limiting assembly. The expansion assemblies are located on both sides of the clamping surface of a foreign body forceps, and are used to expand the inner wall of a digestive organ along the long axis direction of the foreign body. The limiting assembly is located outside the expansion assemblies, and limits the expansion direction of the expansion assemblies along the short axis direction of the foreign body. The cross section of the limiting assembly is a hollow H-shaped structure, and the H-shaped structure is filled with the expansion assemblies. The ends of the transverse part of the H-shaped structure are provided with sliding members, and the inside of the H-shaped structure is provided with sliding grooves. The sliding members can slide along the extension direction of the transverse part of the H-shaped structure along with the expansion of the expansion assemblies. The vertical part of the H-shaped structure is provided with an expansion through hole, and the expansion through hole is a through hole parallel to the extension direction of the transverse part of the H-shaped structure. The above arrangement realizes directional expansion along the long axis of the foreign body, and reduces the risk of tissue damage in the operation of extracting the impacted foreign body in the digestive tract.
