Embodiment Construction

[0020]High simulation human body model head (1), facial features (2), neck (3), torso (4), upper limb model (5-1, 5-2), lower limb model (6-1, 6-2), The simulated skin (7) is made by injecting thermoplastic elastomer TPE into a metal mold, sending it into a rubber-coated furnace and heating it in a rubber-coated rotomolding machine at about 200°C, or using high-elastic addition silicone rubber to mold it in a mold. The simulated subcutaneous tissue (8) and muscles (9) of the model's head (1), facial features (2), neck (2), and torso (4) are injected with PU material into the mold to make PU foam and attached to the simulated skin (7) The inner layer is not only soft but also elastic. Humerus (10-1, 10-2), ulna (11-1, 11-2), radius (12-1, 12-2), femur (13-1, 13-2), tibia (14- 1, 14-2), fibula (15-1, 1-2), etc. are equipped with simulated marrow cavity (SQ), and metaphysis is equipped with simulated cancellous bone (SZ); humerus (10-1, 10- 2), ulna (11-1, 11-2), radius (12-1, ...

Abstract

The invention relates to a medical teaching aid, in particular to the manufacture of simulated subcutaneous tissue used for simulating skin of high-simulation human body model and TPE and other thermoplastic elastic bodies for simulating muscles, a skeleton is formed by using hard PVC and a 10% X-ray contrast agent mould and is provided with a simulated bone marrow cavity, and a metaphyseal end isprovided with simulated cancellous bone; the skeleton can be developed on an X-ray film without metal artifacts; the limbs on one side are made into various fractures with fracture lines/sections andare provided with a full-automatic blood circulation simulator for simulating the connection of arterioles; a simulated joint dislocation is made on the other side of the limbs without fracture; thefirst aid of limbs fracture can be fixed by a small splint, external fixation such as small splint and the like can be adopted after the fracture is manually restored, and complicated fracture can betreated by internal fixation of operation, so that the injured artery has lifelike small artery jet bleeding during the operation; the model can be used for carrying out various orthopedic operationssuch as bone traction, reduction of joint dislocation and the like, the model is used for carrying out orthopedic emergency treatment and various orthopedic operation skills training on medical students in the department of bone injuries in medical colleges and hospitals, and the teaching effect is obviously improved.

Description

technical field [0001] The invention relates to the technical field of medical education equipment, in particular to an orthopedic first aid and operation training assessment model. Background technique [0002] In clinical medicine, limb fractures and joint dislocations are one of the most common diseases, and they are one of the key points and difficulties in medical education and medical practitioner examinations. The existing limb fracture teaching model has a poor simulation level and can only be used for first-aid training of fracture external fixation. The joint connection is made of metal, and X-ray photography cannot be performed. The bone does not have a marrow cavity, and the metaphysis of the bone has no spongy bone. Therefore, the simulation effect is not realistic, and skills training and assessment such as internal fixation of fracture surgery and manual reduction of joint dislocation cannot be carried out, which affects the training and improvement of medical...
