The utility model provides a male dog
urethral catheterization teaching model, which comprises a model main body, the model main body is provided with a
penis module, the front side of the
penis module is sequentially connected with a
penis turtle head ball module and a penis head extension module, and the outer surface of the penis head extension module is coated with a penis prepuce; the penis module is of a hollow structure, a
urethra and a seminiferous duct are arranged in the penis module, the back side of the penis module is sequentially connected with the bladder module and the
prostate module, the front side of the
prostate module is connected with the seminiferous duct, the seminiferous duct is connected with the testis module through a
groin duct, and the bladder module is connected with the
kidney module through a
ureter. The physiological anatomical structure is improved, the
urinary system and the
reproductive system of the male dog are combined, the content is closer to the theoretical course content, and theoretical course model observation is facilitated; due to the optimization of the urogenital
system, the
pathological content explanation is more convenient and easy to understand; and a prepuce
pressure sensor, a
urethra pressure sensor and a
bladder pressure sensor are added, so that the operation is closer to a clinical real scene.
