Abstract
The utility model provides a simple demonstrator for human body breathing principle, which belongs to the field of biological teaching aid instrument. The demonstrator has a rectangular cover, with bottom side opened. Conduits are hermetically provided on the upper portion, with upper terminal communicating with outside. A three-way pipe is hermetically disposed on lower portion of the conduit, with the other two terminals hermetically connected with air bags. Rubbery pieces are respectively provided on two opposite disposed lateral surfaces with ventilation pores opened thereon, springs are provided between rubbery pieces and the cover, an elastic rubbery membrane is hermetically disposed on opening at bottom portion of the cover, hooks are provided on bottom surface of the elastic rubbery membrane. The simple demonstrator for human body breathing principle simulates chest of human body by the cover, simulates trachea of human body by conduits, simulates lung of human body by air bags, and simulates chest type breathing, abdomen type breathing and mixed breathing by composite movement of pressing rubbery membrane with spring and pulling and pushing hooks upwards and downwards, thus improves teaching quality for teacher.
Description
1, technical field
The utility model relates to bioconversion medium technique with the apparatus field, the simple and easy apparatus for demonstrating of specifically a kind of human body respiration principle.
2, background technology
Common people's breathing is to mix to breathe, and is the hybrid breathing of abdominal respiration and thoracic breathing.Wherein the abdominal respiration diaphragm that is meant human body makes the volume in thoracic cavity become big by lifting, thereby pressure diminishes and allows air enter the breath method of lung.Thoracic breathing is meant that human body passes through the contraction and the diastole of rib flesh, thereby changes the volume and the pressure in thoracic cavity, the method that allows air suck.Common people's breathing that is to say that the breathing pattern of these two kinds of actions has.The present existing relevant apparatus that can demonstrate human body respiration and few in bioconversion medium, what have also can only only can reflect a kind of respiratory movement, yet the demonstration apparatus of only a few can react respiratory movement comprehensively, but its complex structure, bulky, demonstration operation is very inconvenient, be unfavorable on the classroom, doing simple and clear object teaching, can not well stay very dark impression or attract students'interest in learning to the student.
3, summary of the invention
Technical assignment of the present utility model is to solve the deficiencies in the prior art, provides a kind of human body respiration principle simple and easy apparatus for demonstrating.
The technical solution of the utility model realizes in the following manner, the simple and easy apparatus for demonstrating of human body respiration principle, its structure comprises cover body, conduit, three-way pipe, air bag, cover body is the rectangular parallelepiped shell shaped cover, and the cover body bottom is uncovered, and top is provided with conduit, be tightly connected between conduit and the cover body, the conduit upper end communicates with the external world, and the lower end is tightly connected and is provided with three-way pipe, and the two ends in addition of three-way pipe respectively are sealedly connected with an air bag; Two the relative sides that have air hole on the cover body are respectively arranged with rubber, be tightly connected around rubber and the cover body side, be provided with spring between rubber and the cover body, the uncovered upward sealing of cover body bottom is provided with rubber elastic membrane, and rubber elastic membrane bottom center is provided with drag hook.
The utility model has the advantages that:
The simple and easy apparatus for demonstrating of this human body respiration principle utilizes the thoracic cavity of cover body simulation human body, the tracheae of conduit simulation human body, the lung that air bag is simulated human body, come to inflate in cover body by the air hole on the cover body with hand by the demonstrator by the rubber of pressure zone spring, the openhanded skin that comes unglued aspirates the space of gas between rubber and cover body in the cover body by resetting of spring, contraction and the diastole of human body by rib flesh simulated in these two actions, thereby change the volume and the pressure in thoracic cavity, allow air suck and discharge the method for the thoracic breathing of lung.The simple and easy apparatus for demonstrating of this human body respiration principle also passes through the rubber elastic membrane of cover body bottom, the demonstrator comes upwards the push-and-pull hook and pulls down drag hook by hand, the diaphragm that such reciprocating action simulation realizes human body makes the volume change in thoracic cavity by lifting, thereby pressure change allows air enter and discharges the abdominal respiration method of lung.The simple and easy apparatus for demonstrating of this human body respiration principle is simple in structure, intuitive, clear, just can simulate simple thoracic breathing, simple abdominal respiration fully and mix respiratory movement by simple action, can improve the efficient of teachers ' teaching demonstration, favourable improving the quality of teaching.
