The volume of the air storage bag 3 is reduced when the air storage bag is extruded by an operator, the air in the air storage bag 3 enters the lung model 2 to enlarge the lung model 2 when the air storage bag 3 is extruded, and the air storage bag 3 is in a contraction state; can extrude gas storage bag 3 when using respiratory nursing training model and make it produce a pre-pressure when operating personnel, when operating personnel loosens the gas storage bag 3 in the hand, when the pre-pressure reduces, the volume of gas storage bag 3 can grow, and the gas in the lung model 2 can enter into gas storage bag 3, and lung model 2 can reduce, and gas storage bag 3 is in the expansion state this moment. The operator switches the air storage bag 3 back and forth between the expansion state and the reduction state to change the size of the lung bag model 2, the size change of the lung bag model 2 can change the residual space in the pleural cavity model 1, and because the pleural cavity model 1 is closed, the pressure in the pleural cavity model 1 can be changed when the residual space in the pleural cavity model 1 is changed.
Be provided with the injection interface 5 of intercommunication internal and external environment on pleural cavity model 1, injection interface 5 is used for being connected with external syringe, can send into gas or liquid in the inner chamber of pleural cavity model 1 to simulate the pathological process of pneumothorax or hydrothorax, in order to guarantee the leakproofness behind liquid or the gaseous entering pleural cavity model 1, be provided with the interface block structure who carries out the shutoff to injection interface 5 on injection interface 5, adopt in this embodiment with injection interface 5 complex interface sealing cap 51. Because the pleural cavity model 1 is able to simulate pathological processes of pneumothorax and hydrothorax, the model can be used to train the treatment of pneumothorax and hydrothorax with a drainage method. Still be provided with the drainage tube that is used for being connected with drainage bottle 11 on the pleural cavity model 1, the drainage tube is including setting up pneumothorax drainage tube 8 at pleural cavity model 1 top and setting up the liquid chest drainage tube 9 in pleural cavity model 1 bottom.

Still can dismantle on the pleural cavity model 1 and be provided with the thorax puncture hole 6 that is used for training the puncture, the shutoff has removable puncture hole sealing plug 7 on the thorax puncture hole 6, can use sharp objects such as syringe needle to pierce through puncture hole sealing plug 7 in order to simulate human puncture treatment when training.
As shown in fig. 2 and 3, when the respiratory system nursing training model of the utility model is used by an operator, the drainage treatment of pneumothorax can be trained when the drainage bottle 11 is communicated with the pneumothorax drainage tube 8. Before training begins, the lung bag model 2 is inflated by inflating gas, and then the pleural cavity model 1 is inflated by inflating gas to simulate the pathological process of pneumothorax: can extrude lung bag model 2 after filling into certain gas in pleural cavity model 1, during gas in the lung bag model 2 can follow the trachea and enter into gas storage bag 3, operating personnel can more directly perceivedly see the change of lung bag model 2 size. The operator can then communicate the pneumothorax drainage tube 8 with the drainage bottle 11 to simulate treatment of pneumothorax using drainage: after the drainage bottle 11 is communicated with the pneumothorax drainage tube 8, the pneumothorax drainage tube 8 is communicated with the drainage bottle 11 through a connecting tube 10 on the drainage bottle 11, liquid is contained in the drainage bottle 11, the air inlet end of the connecting tube 10 is connected with the pneumothorax drainage tube 8, the air outlet end of the connecting tube 10 is positioned below the liquid level, and the drainage bottle 11 is communicated with the atmosphere, so that the liquid in the drainage bottle 11 is pressed into the connecting tube 10 by the atmosphere, and an operator can visually see that a section of liquid column higher than the liquid level exists in the connecting tube 10.
Operating personnel is through extrusion gas storage bag 3, during making gas enter into lung bag model 2 among the gas storage bag 3, 2 grow of lung bag model, make residual space diminish in the pleural cavity model 1, the pressure grow in the pleural cavity model 1, during gas in the pleural cavity model 1 was crowded into pneumothorax drainage tube 8 and connecting pipe 10, can extrude the liquid column that originally exists in connecting pipe 10 when gas row goes into drainage bottle 11, make the liquid column by crowded downwards in drainage bottle 11. The operating personnel relaxes gas reservoir 3 afterwards, because gas reservoir 3 is sealed with lung chamber model 2, the gaseous total amount is unchangeable, gas in the lung chamber model 2 can enter into gas reservoir 3, the volume of lung chamber model 2 diminishes, remaining space grow in the pleural cavity model 1, pressure diminishes in the pleural cavity model 1, atmospheric pressure can be pressed the liquid in the drainage bottle 11 into connecting pipe 10, but drainage bottle 11 will be less than pneumothorax drainage tube 8 when placing, atmospheric pressure is not enough to be pressed liquid into pleural cavity model 1, so operating personnel can only see one section liquid column that can rise in connecting pipe 10 when relaxing gas reservoir 3.
In the process, the operator can simulate the respiratory movement of the lung in the drainage process by squeezing and loosening the gas storage bag 3, the change of the pressure in the chest cavity can be caused when the lung breathes, and the pleural cavity model 1 can be seen to exhaust outwards through the liquid column lifting condition in the connecting pipe 10 on the drainage bottle 11 and the bubbles in the drainage bottle 11. Along with extrude many times, relax the operation of gas storage bag 3, can see the undulant condition about the liquid column in the connecting pipe 10, can judge the patency of drainage through the fluctuation of liquid column, can also reflect the inflation degree of lung, can analyze out the intrathoracic pressure situation of change according to the inflation degree of lung. The connection tube 10 may be disconnected from the drainage tube after the fluctuation of the liquid column in the connection tube 10 gradually disappears with a plurality of operations.
An operator can also use the hydrothorax drainage tube 9 to be connected with the drainage bottle 11 to train the hydrothorax drainage treatment, the operation of the operator is the same as the pneumothorax drainage treatment, and the respiratory action of the lung in the hydrothorax drainage process is simulated by repeatedly extruding and loosening the gas storage bag 3. The difference lies in the phenomenon of liquid column fluctuation: because what need the drainage in the thorax is pleural effusion, therefore among the thorax drainage tube 9 and the connecting pipe 10 intercommunication, some hydrops have just got into in the thorax drainage tube 9, it is also one section liquid column directly perceived, can crowd original liquid column in the connecting pipe 10 to the drainage bottle 11 when hydrops liquid column is promoted by pressure and gets into drainage bottle 11, operating personnel is difficult to judge the undulant condition of liquid column, consequently operating personnel can add the staining solution that the colour is different with liquid in the drainage bottle 11 to simulate blood or pus in pleural cavity model 1 when the operation, so that operating personnel observes the undulant condition of liquid column in the connecting pipe 10 more directly perceivedly.
