Description

Stomach tube imbedding operation training model for teaching

Technical Field

The application relates to a teaching model, especially, relate to a stomach tube is put into operation training model for teaching.

Background

Gastric tube implantation, also known as gastric intubation. The gastrointestinal decompression tube is mainly used for draining gastrointestinal contents through the gastrointestinal decompression tube or for patients incapable of taking food orally, and fluid food is infused from the stomach tube, so that the patients can be ensured to take enough nutrition, moisture and medicine, and the early recovery is facilitated.

After the gastric tube is placed, whether the gastric tube is positioned correctly or not needs to be determined. There are generally three types of test methods: firstly, a gastric juice extraction method, which is a method for determining whether a gastric tube is the most reliable in the stomach; secondly, by the air-water sound method, namely placing the stethoscope in the stomach area of a patient, rapidly injecting 10 ml of air into the stomach through the stomach tube, and hearing the air-water sound; thirdly, a bubble escape method is adopted, and the tail end of the stomach tube is placed in a treatment bowl containing water to see whether bubbles escape.

Although there are various teaching models of gastric tube placement, such as "nasal feeding operation training device" disclosed in CN 109935129A, and "human trachea and gastric tube intubation model" disclosed in CN 213400206U, these models cannot be used to verify whether the gastric tube is placed in the correct position by the above three verification methods.

Disclosure of Invention

In view of the above problems, the present application aims to provide a gastric tube placement operation training model for teaching, which can verify whether a gastric tube is placed correctly through the above three verification methods when practicing gastric tube placement.

The stomach tube imbedding operation training model for teaching is formed into a human body model comprising a head, a chest and an abdomen; the head of the model is formed with an oral cavity and a nasal cavity corresponding to the anatomical structure of the human body; the chest of the model is formed with a left lung, a right lung, a stomach, an airway and an esophagus;

the stomach is connected with a first pipeline which extends to the outside of the model; the first pipeline is used for injecting liquid into the stomach so as to implement a pneumo-acoustic method and a gastric juice extraction method;

the left lung is connected with a second pipeline which extends to the outside of the model;

the right lung is connected with a third pipeline which extends to the outside of the model;

the second pipeline and the third pipeline are respectively connected to a fourth pipeline; the fourth pipeline is connected with an elastic saccule; the elastic balloon is used to repeatedly inject or aspirate gas into or from the left and right lungs, thereby simulating respiratory movement of the human lungs to perform a bubble escape method.

Preferably, the chest and abdomen are formed to be transparent.

Preferably, the outside of the chest and abdomen is worn with an opaque coat.

Through the teaching of this application with stomach tube operation training model of putting into, when carrying out stomach tube and putting into teaching training, can be like put into on the true man and put into like implementing stomach tube, whether to put into correctly through drawing gastric juice method, gas water sound method, bubble escape method verification stomach tube. Meanwhile, students can directly see the incorrect operation of the rubber stomach tube into the trachea or the lung and the reaction of the patient, and the incorrect operation on a real person after entering the clinic is avoided.

Detailed Description

Next, the operation training model for stomach tube placement for teaching of the present application will be described in detail with reference to the accompanying drawings.

The teaching gastric tube imbedding operation training model is formed into a human body model comprising a head part, a chest part and an abdomen part 1. The head of the model is formed with an oral cavity and a nasal cavity corresponding to the anatomical structure of the human body. The chest of the model is formed with a left lung 11, a right lung 12, a stomach 20, an airway, an esophagus.

The stomach is connected with a first pipeline 21, and the first pipeline 21 extends to the outside of the model; the first line 21 is used to inject fluid into the stomach 20 to simulate gastric fluid.

The left lung 11 is connected with a second pipeline 11a, and the second pipeline 11a extends to the outside of the model;

the right lung 12 is connected with a third pipeline 12a, and the third pipeline 12a extends to the outside of the model;

the second pipe 11a and the third pipe 12a are connected to the fourth pipe 13, respectively; the fourth pipeline 13 is connected with an elastic balloon 30; the elastic balloon 30 is used to simulate 43 respiratory movements of the human lungs. The air is repeatedly injected into the left and right lungs 11 and 12 through the elastic balloon 30 or sucked out from the left and right lungs 11 and 12, thereby simulating the respiratory motion of the human lungs.

The chest and abdomen may be formed transparent. Thus, whether the stomach tube is put into the correct position or not can be visually observed.

The outer side of the chest and the abdomen is worn with the opaque coat, so that a trainee cannot be visually assisted in tube placement during tube placement training and is as close to a real tube placement environment as possible.

After the trainee inserts the stomach tube through the oral cavity or the nasal cavity, because the liquid is injected into the stomach through the first pipeline, the stomach tube can be inflated through the non-inserted end of the stomach tube, and verification can be performed by using an air-water sound method; or the suction can be performed through a gastric tube, and verification can be performed by using a gastric juice extraction method; the non-inserted end of the stomach tube can be placed into water, the elastic saccule is repeatedly extruded, whether bubbles emerge from the water or not is observed, and verification is carried out by using a bubble escape method.
