An ultrasonic diagnosis teaching aid applied to gall-bladder stones is shown in fig. 1-3 and comprises a gall-bladder model 101 and an abdominal cavity model 102, wherein the gall-bladder model 101 simulates a human gall-bladder, the gall-bladder model 101 comprises a transparent gall-bladder shell, at least one calcium carbonate ball 103 for simulating stones and gel for fixing the calcium carbonate ball 103 are arranged in the gall-bladder shell, the abdominal cavity model 102 simulates a human abdominal cavity, the abdominal cavity model 102 comprises an abdominal cavity shell, and a mounting hole 105 for inserting the gall-bladder model 101 is formed in the side edge of the abdominal cavity shell.

The shapes of the gallbladder model 101 and the abdominal cavity model 102 simulate the real gallbladder and the abdominal cavity of a human body vividly, and according to the actual position of the gallbladder in the abdominal cavity, a mounting hole 105 is formed in the side surface of the abdominal cavity model 102 closest to the gallbladder model 101, and the diameter of the mounting hole 105 needs to be larger than the maximum diameter of the gallbladder model 101, so that the gallbladder model 101 can be put in or taken out conveniently. The transparent gallbladder shell can facilitate students to visually observe the quantity, size and distribution position of stones in the gallbladder model 101. The calcium carbonate ball 103 for simulating the calculus should be made into the shape and the size the same as or similar to those of the real gall bladder calculus, and has complete specification and enough quantity. The gel is used for fixing the calcium carbonate balls 103 for simulating the calculus to different parts, and ultrasonic detection is carried out on the gallbladder models 101 with different calculus parts, different calculus numbers and sizes, so that teaching demonstration of teachers and exercise of students are facilitated, and the mastering and understanding of the diagnosis process are deepened.

In this embodiment, the abdominal cavity model 102 further includes a flexible inner container 104, the flexible inner container 104 is connected to the edge of the mounting hole 105, and the closed space formed by the abdominal cavity outer shell and the flexible inner container 104 can be filled with simulated body fluid. The space between the flexible bladder 104 and the mounting hole 105 is sufficient to accommodate the gallbladder model 101. The flexible liner 104 is fixedly disposed at the edge of the mounting hole 105, so that an enclosed space is formed between the flexible liner 104 and the abdominal cavity model 102, the enclosed space is used for containing substances simulating body fluid, and the simulated body fluid can be water or normal saline. Under the pressure of the simulated body fluid, the flexible liner 104 gradually approaches and is attached to the surface of the gallbladder model 101, so that the in-vivo environment of a normal human body can be simulated more realistically.

The abdominal cavity model 102 can also be directly made into a transparent saccular structure filled with water, and the gall bladder model 101 is fixed on the inner wall of the abdominal cavity model 102, so that the simple teaching aid is convenient for teachers and students to operate and observe from various angles, and the manufacturing cost is lower.

In this embodiment, a clamping groove is arranged at the mounting hole 105, and a buckle adapted to the clamping groove is arranged at the gallbladder model 101. In order to fix the gallbladder model 101 placed in the abdominal cavity model 102 at a corresponding position, the gallbladder model 101 can be quickly mounted and dismounted through the matching of the clamping grooves and the buckles. The gallbladder models 101 can be designed to be multiple, the positions, the number and the sizes of the simulated stones in the gallbladder models can be reasonably arranged according to typical various clinical diagnosis results, and due to the detachable design of the gallbladder models 101, teachers or students can quickly change the gallbladder models 101, so that teaching demonstration and experiment practice are facilitated.

In this embodiment, the material of the gallbladder shell is any one of polyethylene, polypropylene and glass. Polyethylene, polypropylene, glass these materials are transparent, not only are convenient for observe, can ensure moreover that the supersound can pierce through this gall bladder shell, and then detect the simulation calculus in the gall bladder model 101, are favorable to forming clear ultrasonic image.

In this embodiment, the material of the abdominal shell is silica gel or rubber. The abdominal cavity outer shell needs to keep a stiff shape, so the silica gel or the rubber for manufacturing the abdominal cavity outer shell needs to have certain hardness, and the hardness of the silica gel or the rubber can be regulated and controlled by different raw materials and prepared hardness formulas.

In this embodiment, the flexible inner container 104 is made of silicone or rubber. Compared with the abdominal cavity shell, the flexible inner container 104 needs silica gel or rubber with lower hardness, so that the use requirement of flexibility is realized, the flexible inner container can be better tightly attached to the gallbladder shell of the gallbladder model 101, and a more real human body fluid environment is simulated.

In the embodiment, the surfaces of the gallbladder shell and the side surfaces of the flexible liner 104 contacting with the gallbladder model 101 are all provided with polytetrafluoroethylene coatings. The polytetrafluoroethylene is a high molecular compound formed by polymerizing tetrafluoroethylene, and has excellent chemical stability, corrosion resistance, sealing property, high lubrication non-sticking property, electrical insulation property and good ageing resistance. Due to the high lubrication and non-adhesiveness of the polytetrafluoroethylene, the adhesion and separation of the gallbladder shell and the flexible liner 104 are more convenient and faster due to the polytetrafluoroethylene coating, the gallbladder model 101 and the flexible liner 104 are protected, and the service life is longer.

In this embodiment, a discharge port is provided at the abdominal shell, and the discharge port can be provided at the neck of the abdominal model 102, and a cap adapted to the discharge port is provided on the discharge port. The discharge port is used for simulating the injection and discharge of body fluid. The simulated body fluid can be water, and water is injected through the discharge port before use; after the ultrasonic diagnosis teaching aid is used, water is discharged through the discharge port, so that the ultrasonic diagnosis teaching aid applied to gallstone is convenient to take, place and use.

The use method of the ultrasonic diagnosis teaching aid applied to the gallstone is concretely explained by taking teaching demonstration as an example: before the ultrasonic diagnosis teaching aid is used, the gallbladder model 101 is required to be installed inside the abdominal cavity model 102, the inside of the abdominal cavity model 102 is filled with water from the discharge port, the cover is screwed tightly, the ultrasonic diagnosis teaching aid is horizontally placed on a laboratory bench, a teacher uses an ultrasonic probe to aim at the gallbladder model 101 to detect, an image of the gallbladder model 101 is displayed on a B ultrasonic machine display in real time, the teacher guides students to analyze and judge the image, the position, the size and the quantity of simulated stones inside the gallbladder model are presumed, then the teacher can take out the gallbladder model 101, and the gallbladder model 101 is compared with the ultrasonic image, so that the students can understand and master the ultrasonic diagnosis process of the gallbladder stones more clearly and intuitively. After the ultrasonic diagnosis teaching aid is used, water in the abdominal cavity model 102 can be discharged through the discharge port, so that the ultrasonic diagnosis teaching aid is convenient to store.

The above-mentioned embodiments are only specific embodiments of the preferred embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art is within the technical scope of the present invention, and according to the technical solution of the present invention and the design of the present invention, equivalent replacement or change should be covered in the protection scope of the present invention.
