Description

Technical Field

[0001] The present invention relates to the technical field of percussion models, and specifically to a teaching model for physical examination of the chest and abdomen. Background Art

[0002] In the field of medical education, physical examination of the chest and abdomen is an important basic skill in clinical practice. As a core teaching tool, the percussion model needs to accurately simulate the physiological structure of the human chest and abdomen to help medical students master operation techniques such as percussion and palpation. Existing percussion models usually have the touch and feedback functions imitating human tissues, but there is still room for optimization in their application in teaching scenarios. Medical students need to repeatedly operate the model to form muscle memory, and whether the structural design of the model is convenient for the coherence of the teaching process directly affects the learning efficiency.

[0003] During the teaching process, to ensure hygiene and safety, the surface of the model needs to be comprehensively disinfected before and after each use. However, most traditional chest and abdomen examination models are in a fixed posture. When disinfecting, it is necessary to manually turn the model to cover the back and hidden parts. The operation process is cumbersome and the model is easily damaged due to uneven force. Especially when the model is large, the problem of inconvenient turning is more prominent, which not only consumes manpower but also may affect the service life of the model due to frequent handling. There is an urgent need for a structural design that can achieve convenient turning to simplify the disinfection process and improve the teaching experience. Summary of the Invention

[0004] In view of the problems in the prior art, the present invention provides a teaching model for physical examination of the chest and abdomen.

[0005] The technical solution adopted by the present invention to solve its technical problems is: a teaching model for physical examination of the chest and abdomen, including a model main body. A regulating component for turning the model main body is arranged at the lower end of the model main body. A supporting component for supporting the regulating component is arranged at the lower end of the regulating component. A disinfection component for disinfection is arranged on one side of the regulating component. The supporting component includes a bottom plate, and extrusion grooves are formed on both sides of the upper end of the bottom plate. The regulating component includes a support frame. Limit grooves are formed on both sides of the support frame. Two transmission rods are slidably connected in the limit grooves. Transmission plates are respectively hinged at both ends of the two transmission rods. A round shaft is jointly hinged at the other ends of the two transmission plates. Guide blocks are fixedly connected to one ends of the round shafts. Guide grooves corresponding to the guide blocks are formed on the support frame. The guide blocks are slidably connected with the guide grooves. Mounting plates are fixedly connected to the other ends of the round shafts. The model main body is fixedly installed between the two mounting plates. A gear is fixedly connected to one of the round shafts. A rack is fixedly connected to the support frame corresponding to the gear. The gear is meshed with the rack.

[0006] Specifically, the support assembly also includes a handle and a plurality of universal wheels, the handle is fixedly connected to one side of the base plate, and the plurality of universal wheels are fixedly connected to the lower end of the base plate.

[0007] Specifically, the adjustment assembly also includes a support block, which is fixedly connected to the upper end of the support frame. The support block is fixedly connected to a guide rod, and two first springs are sleeved on the outer wall of the guide rod. The two transmission rods are slidably connected to the guide rod.

[0008] Specifically, the adjustment assembly also includes a plurality of second springs, which are fixedly connected to the lower end of the support frame, and the second springs are hollowed out and fixedly connected to a limiting shaft, and the second springs are fixedly connected to the bottom plate, and the limiting shaft is slidably connected to the bottom plate.

[0009] Specifically, the disinfection assembly includes a disinfection tank and a disinfection tube. The disinfection tank is fixedly mounted on a support frame. A delivery pump is fixedly mounted on one side of the support frame close to the disinfection tank. The disinfection tube is rotatably connected to one side of the support frame.

[0010] Specifically, the disinfection tank is connected to the delivery pump pipeline, the delivery pump is connected to the disinfection pipe pipeline, the disinfection pipe is designed in an L-shaped structure, and an atomizing nozzle is fixedly installed on one side of the disinfection pipe.

[0011] Specifically, the extrusion groove is opened in an isosceles trapezoidal structure, and the transmission rod is in contact with the extrusion groove.

[0012] The beneficial effects of the present invention are as follows: when the support frame is pressed, the extrusion groove of the bottom plate forms a linkage with the transmission rod, and through the meshing transmission of the gear rack and the cooperation between the guide block and the guide groove, the model body automatically completes the flipping when the force is applied. This design does not require additional power drive, and the model can be flipped 180 degrees only by pressing, which significantly reduces the difficulty of operation during disinfection before and after teaching, and avoids the inconvenience and potential risk of injury of traditional manual flipping. At the same time, the spring and limit structure in the adjustment component ensure the stability and buffering effect of the flipping process, and improve the safety of the model. With the rotatable disinfection tube and the atomizing nozzle, the flipped model can be more conveniently disinfected in all directions, effectively ensuring the hygiene standards of the teaching environment. It provides a more efficient and comfortable operating experience for medical students. BRIEF DESCRIPTION OF THE DRAWINGS
