AI Technical Summary

Technical Problem

Existing catheterization simulation training devices cannot reproduce the morphological changes of the urethra under complication conditions, resulting in operators lacking targeted emergency treatment training and making it easy for catheter insertion difficulties and secondary urethral injury to occur.

Method used

A training robot for simulating and handling complications of urinary catheterization was designed. By setting a telescopic cavity in an elastomer and opening multiple cavities on a simulated prosthesis, the expansion of the cavities is controlled by a water pump to simulate pathological states such as urethral torsion, stenosis and obstruction, thereby training the operator's emergency handling capabilities.

Benefits of technology

It effectively simulates the pathological changes of the urethra under complications, improves the operator's emergency response capabilities, reduces the risk of patient injury, and improves the quality of medical care.

Abstract

The invention relates to the technical field of scientific demonstration teaching aids, in particular to a urethral catheterization complication simulation and emergency treatment training robot which comprises a dummy body and further comprises an elastic body and a water tank, the elastic body is arranged on one side of the interior of the dummy body, and a through hole is formed in the side wall of the dummy body and the face, attached to the elastic body, of the dummy body in a penetrating mode; the water tank is arranged on one side in the dummy body and is distributed front and back with the elastic body; a plurality of telescopic cavities are formed in the elastic body, the telescopic cavities are expanded by injecting water into the telescopic cavities so as to extrude the simulation prosthesis and the urethra, the diseases of urethra lumen distortion and walking deviation caused by bladder pressure increase can be simulated, and therefore the emergency treatment capacity of an operator for coping with the conditions can be trained.
