AI Technical Summary

Technical Problem

Existing teaching equipment for simulating closed thoracic drainage puncture cannot effectively simulate patients of different body sizes, resulting in assessment results that fail to meet actual treatment needs.

Method used

A simulated closed thoracic drainage puncture device was designed, including a dummy component and a simulated drainage puncture device. It adopts adjustable body components and sensors to simulate the thoracic cavity structure of different body shapes and patients. Through the combination of support base, body components, simulated tissue and simulated drainage puncture device, it realizes the capture of body changes and real-time information.

Benefits of technology

It increases the difficulty and accuracy of teaching assessments, better simulates actual patient conditions, improves the operational skills of medical staff, prevents cheating, and meets actual treatment needs.

Abstract

The present application belongs to the technical field of medical teaching equipment, and provides a simulated thoracic cavity closed drainage puncture device.The present application comprises a dummy assembly, the dummy assembly comprising a support seat, a body assembly and a simulated thoracic cavity; the body assembly is arranged on the support seat, the simulated thoracic cavity is arranged on one side of the body assembly and is connected with the body assembly; wherein the body assembly is internally provided with simulated tissue for simulating fat; the simulated thoracic cavity is internally filled with liquid for simulating effusion; and a simulated drainage puncture device, the simulated drainage puncture device being capable of penetrating through the body assembly and extending into the simulated thoracic cavity; the simulated drainage puncture device comprises a puncture device main body and a sensing assembly, and the sensing assembly is arranged on the puncture device main body.The device can effectively realize the body change of the dummy assembly, so as to effectively improve the teaching examination difficulty, and more conveniently conform to the actual situation, thereby avoiding the reduction of the examination difficulty caused by the traditional use of standardized human body simulation models, and not conforming to the actual situation.
