Abstract
The utility model relates to a dynamic flail-chest teaching model including a chest model (10), a rebreathing air sac (20), an endotracheal conduit (30) and a pressure-control sensing pigment package (40). One end of the endotracheal conduit (30) is connected with the rebreathing air sac (20) and the other end of the endotracheal conduit (30) is inserted into a vertebrate trachea (107) of the chest model (10). The pressure-control sensing pigment package (40) is embedded into a left lung (102) of the chest model (10). The dynamic flail-chest teaching model is simple in structure, convenient to use, capable of being used for flail-chest directly observable teaching demonstration and displaying dynamically pathologic changes of a flail chest and effects of emergency treatments so that the teaching is vivid and understanding is facilitated and memories are deepened for students.
Description
Technical field:
The utility model relates to a kind of teaching mode, more specifically to a kind of dynamic flail chest teaching mode.
Background technology:
Flail chest refers to Duo Gen many places fracture of rib, making the local wall of the chest lose rib supports and softens, the wall of the chest causing floats and has destroyed the stability of thorax mechanical motion, occur that the softened zone wall of the chest caves in when air-breathing, evagination paradoxical breathing during expiration, causes resistance of respiratory tract increase to make to breathe usefulness attenuating and causes serious hypoxemia and carbon dioxide retention.Flail chest is the thoracic injury that a class is more serious, multiple with male sex person between twenty and fifty, and traumatogenic reason mostly is traffic accident injury, crush injury, presses, injures by a crashing object, treats not in time or deal with improperly serious consequences such as can causing respiratory failure and disturbance of circulation.In field research process, light is with pathophysiological change and treatment method and the effect of the flail chest of the oral narration of teacher, student is difficult to understand mechanism and treatment method and the effect that flail chest causes hypoxemia, carbon dioxide retention, if the teaching mode that can have a kind of flail chest intuitively dynamically to show, problem just can be readily solved, so design a kind of dynamic flail chest teaching mode, is very useful.
Utility model content:
The purpose of this utility model is exactly for the deficiencies in the prior art, and a kind of dynamic flail chest teaching mode is provided.The utility model is simple in structure, easy to use, can do the teaching of flail chest object teaching, can dynamically show pathological change and the emergency treatment effect of flail chest, makes to impart knowledge to students vivid, is convenient to student and understands, and deepens the advantage of student memory.
Technology solution of the present utility model is as follows:
A kind of dynamic flail chest teaching mode, comprise thoracic cavity model, breathing bag, tracheal catheter and pressure are controlled induction pigment bag, described tracheal catheter one end is connected with breathing bag, the other end inserts in the tracheae on the model of thoracic cavity, the left lung of thoracic cavity model is embedded with a pressure and controls induction pigment bag, thoracic cavity model is an airtight lacuna, this lacuna is by left thoracic cavity, right thoracic cavity and vertical diaphragm form, left lung is positioned at left thoracic cavity, right lung is positioned at right thoracic cavity, the part of heart and tracheae is positioned at vertical diaphragm, lacuna between rib and lung is that left thoracic cavity and right thoracic cavity are vacuum negative pressure condition, rib has fracture softening.
In technique scheme, between described tracheae and left lung, right lung, communicate.
The beneficial effects of the utility model are:
The utility model is simple in structure, easy to use, can do the teaching of flail chest object teaching, can dynamically show pathological change and the emergency treatment effect of flail chest, makes to impart knowledge to students vivid, is convenient to student and understands, and deepens student memory.
Accompanying drawing explanation:
Fig. 1 is the utility model one-piece construction schematic diagram.
In figure: the model of 10, thoracic cavity; 101, left thoracic cavity; 102, right thoracic cavity; 103, vertical diaphragm; 104, left lung; 105, right lung; 106, heart; 107, tracheae; 20, breathing bag; 30, tracheal catheter; 40, pressure is controlled induction pigment bag.
Embodiment:
The following stated is only preferred embodiment of the present utility model, not scope of the present utility model is limited.
Embodiment: as shown in Figure 1, a kind of dynamic flail chest teaching mode, comprise thoracic cavity model 10, breathing bag 20, tracheal catheter 30 and pressure are controlled induction pigment bag 40, described tracheal catheter 30 one end are connected with breathing bag 20, the other end inserts in the tracheae 107 on thoracic cavity model 10, the left lung 102 of thoracic cavity model 10 is embedded with a pressure and controls induction pigment bag 40, thoracic cavity model 10 is airtight lacunas, this lacuna is by left thoracic cavity 101, right thoracic cavity 102 and vertical diaphragm 103 form, left lung 104 is positioned at left thoracic cavity 101, right lung 105 is positioned at right thoracic cavity 102, the part of heart 106 and tracheae 107 is positioned at vertical diaphragm 103, lacuna between rib and lung is that left thoracic cavity 101 and right thoracic cavity 102 are vacuum negative pressure condition, rib 108 has fracture softening.
Between described tracheae 107 and left lung 104, right lung 105, communicate.
Principle of work:
A kind of dynamic flail chest teaching mode, tracheal catheter 30 one end are connected with breathing bag 20, the other end inserts in the tracheae 107 on thoracic cavity model 10, the left lung 102 of thoracic cavity model 10 is embedded with a pressure and controls induction pigment bag 40, thoracic cavity model 10 is airtight lacunas, this lacuna is by left thoracic cavity 101, right thoracic cavity 102 and vertical diaphragm 103 form, left lung 104 is positioned at left thoracic cavity 101, right lung 105 is positioned at right thoracic cavity 102, the part of heart 106 and tracheae 107 is positioned at vertical diaphragm 103, lacuna between rib and lung is that left thoracic cavity 101 and right thoracic cavity 102 are vacuum negative pressure condition, rib 108 has fracture softening, extruding breathing bag 20 can be by tracheal catheter 30 and tracheae 107 to supply gas in lung (simulating autonomous aspiratory action), in pleural cavity, negative pressure increases, the softening wall of the chest caves inward.While being full of 800ml gas in lung, the pressure in lung is controlled induction pigment bag 40 and is discharged a certain amount of disperse pigment, can make gas variable color in lung (can be considered the CO that organism metabolism produces
2), lung elastance retraction produces exhale action, and intrapleural negative pressure lowers, softening wall of the chest outwardly convex, variable color gas is partly extruded tracheae 107, and part is clamp-oned strong laterobronchus and is caused CO
2retention and hypoxemia; Autonomous air-breathing and while exhaling by the simulation of extruding breathing bag 20 and lung elastance retraction, because the left rib 108 fracture wall of the chest float, both sides pleural pressure is unbalanced, can occur that vertical diaphragm 103 swings, and can dynamically show pathophysiological change and treatment method and the effect of flail chest.
