Abstract
The utility model relates to a teaching model and in particular relates to a pulmonary respiration ventilation model. The pulmonary respiration ventilation model comprises an artificial thorax, a Y-shaped tube standing for bronchus, and two balloons standing for the left lung and the right lung, the artificial thorax is a flat bell-shaped transparent elastomer and provided with an upper opening, a bottom opening and a vacuum aspirating hole, the bottom opening is hermetically connected with a rubber membrane standing for diaphragm, the Y-shaped tube standing for bronchus is inverted in the artificial thorax, two tube openings at the lower end are respectively connected with two balloons standing for the left lung and the right lung, the tube opening at the upper end extends out of the upper opening of the artificial thorax and hermitically connected with the upper opening of the artificial thorax through a rubber plug. The model provided by the utility model is similar to the shape of the organism, the external intercostals muscles and the internal intercostals muscles can be displayed clearly so that the student is easy to accept and apply; the physiological character of real intrapleural negative pressure can be formed so as to really display the correct form of outward convex diaphragmatic dome, the normal form and the structure change relation in the respiration ventilation process are reflected while various organ tissue structures in the thorax are reflected, so that the teaching content is more intuitive.
Description
Technical field
The utility model relates to teaching model, specifically a kind of pulmonary respiration ventilation model.
Background technology
At present, the teacher is lecturing the concepts such as expiratory muscle, inspiratory muscles, pleural cavity, intrathoracic negative pressure, and they are when exhaling, inhaling concerning of ventilation at lung, and there is certain difficulty in students ' understanding.Notification number CN 202332047 U disclose a kind of pulmonary respiratory movement model, although can demonstrate human body respiration moves air-breathing and two processes of exhaling, but it only reflects thorax organ-tissue structure, and can not reflect these physilogical characteristics of intrathoracic negative pressure, and is still visual in image not.
The utility model content
The technical problems to be solved in the utility model is: a kind of simple in structure, transparent, thorax directly perceived and lung structure relational model are provided, can truly reflect each structural change relation in the pulmonary respiration scavenging period, simulate the intrapleural negative pressure structure, can be widely used in the pulmonary respiration ventilation model that all kinds of anatomical physiology teaching and personnel's first aid use.
The technical scheme that its technical matters that solves the utility model adopts is:
A kind of pulmonary respiration ventilation model, comprising: the simulation thorax represents bronchial Y tube, represent two balloons of [Dan, described simulation thorax is flat bell transparent elastomer, is provided with suitable for reading, end mouth and vacuum pumping hole, and end mouth is sealedly connected with the rubber diaphragm that is equivalent to diaphram; Describedly represent that bronchial Y tube is inverted in the simulation thorax, two of its lower ends mouth of pipe is connected with two balloons that represent [Dan respectively, one of the upper end mouth of pipe stretch out the simulation apertura thoracis superior and by rubber plug with simulate that apertura thoracis superior is airtight to be connected.
Further, described simulation thorax is cast molding structure of PET material.
Further, described Y tube is glass tube.
Compared with prior art, the beneficial effects of the utility model are:
1. close with the body form, external intercostal muscles, intercostals interni show clear, are convenient to the student and accept and use;
2. can form real these physilogical characteristics of intrathoracic negative pressure, thereby also truly demonstrate convex this correct form in diaphragm top;
3. not only reflect each organ-tissue structure of thorax, also reflect when going out they normal morphology and the respiratory ventilation process in each structural change relation, make the abstract content of courses more directly perceived.
Description of drawings
Fig. 1 is the utility model example structure schematic diagram front view.
Fig. 2 is the utility model example structure schematic diagram side view.
In figure: simulation thorax 1, rubber plug 2, Y tube 3, balloon 4, rubber diaphragm 5, vacuum pumping hole 6.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1, Fig. 2, simulation thorax 1 adopts a cast molding of PET material, is the bell of flattening, is provided with suitable for reading, end mouth and vacuum pumping hole 6, and end mouth is sealedly connected with the rubber diaphragm 5 that is equivalent to diaphram, and the PET material transparency is good, has certain elasticity; Represent that bronchial Y tube 3 is glass tube, caliber 2.5cm, Y tube 3 is inverted in simulation thorax 1, and two of its lower ends mouth of pipe is connected with two balloons 4 that represent [Dan respectively, and it is suitable for reading and by rubber plug 2 and simulate thorax 1 airtight connection the suitable for reading that one of the upper end mouth of pipe stretches out simulation thorax 1.
Use vacuum pump from vacuum pumping hole 6 extracting airs, make the gas in simulation thorax 1 form intrathoracic negative pressure, follow the extraction of gas, two balloons 4 that represent [Dan can change with the shape that is equivalent to the rubber diaphragm 5 of diaphram, locked vacuum pumping hole 6 when balloon 4 and rubber diaphragm 5 reach visual effect in simulation thorax 1, at this moment, two balloons 4 can become large, and rubber diaphragm 8 can be convex.Press simulation thorax 1 with hand, represent air-breathing at the beginning of, then the pressure that slowly alleviates hand represents that external intercostal muscles shrinks, it is large that the thorax anteroposterior diameter becomes, and the convex rubber diaphragm of the slow tractive of another hand, represent contraction of diaphragm simultaneously, footpath, thorax up and down becomes large, in this process, can find balloon 4(lung) constantly becoming large, namely complete breathing process.Other is explained slightly.
This teaching model visual pattern reflects the true relation of thorax and lung structure, follows the fluctuating of thorax, and the ventilation lifelike image of lung also can be simulated some pathologic process such as pneumothorax simultaneously.
Claims (3)
1. a pulmonary respiration ventilation model, comprising: simulate thorax, represent bronchial Y tube, represent two balloons of [Dan, it is characterized in that, described simulation thorax is flat bell transparent elastomer, be provided with suitable for reading, end mouth and vacuum pumping hole, end mouth is sealedly connected with the rubber diaphragm that is equivalent to diaphram; Describedly represent that bronchial Y tube is inverted in the simulation thorax, two of its lower ends mouth of pipe is connected with two balloons that represent [Dan respectively, one of the upper end mouth of pipe stretch out the simulation apertura thoracis superior and by rubber plug with simulate that apertura thoracis superior is airtight to be connected.
