Abstract
The utility model belongs to the technical filed of medical teaching instruments, and specifically relates to a human lung expansion and contraction motion demonstration instrument. The demonstration instrument comprises a base (1) and two lung models (4) arranged above the base (1). The lung models (4) are two hollow rubber balls. Each lung model (4) is peripherally coated by a transparent container (2), and the bottom of each transparent container (2) is connected with an air bag (3). The bottoms of the two air bags (3) are connected by a cross bar (6). A hollow tube (5) is arranged at an upper part of the lung model (4) and is communicated with the interior of the lung model (4). A top outlet of the hollow tube (5) is provided with a thin rod (8) which is fixed on an inner wall of the hollow tube (5) by an elastic belt (9). The human lung expansion and contraction motion demonstration instrument has the advantages of simple structure, convenience and practicality, and can stimulate the breathing states of the human lungs in the thoracic cavity, providing good simulation effect.
Description
Technical field
The utility model belongs to the medical teaching Instrument technology field, particularly a kind of expansion of human body lung and contractile motion demonstrator.
Background technology
In medical education or middle school physiology class, the teacher often uses a model to simulate the function of human organ, and model generally is made up of base and the lung model that is positioned at the base top.Announced a kind of healthy person lung demonstrating model on the evidence-based medicine EBM model net, comprised support and hang over lung model on the support that lung model is connected with inflator by conduit, this model can be demonstrated expansion and the contractile motion of human body lung, helps to improve teaching efficiency.
The utility model content
The purpose of this utility model provides a kind of expansion and contractile motion demonstrator of human body lung, and the two lungs of this demonstrator energy visual simulation human body are at intrathoracic breathing state.
The scheme that the utility model solve the technical problem is: a kind of expansion of human body lung and contractile motion demonstrator, comprise base and two lung models that are positioned at the base top, described lung model is the rubber spheroid of two hollows, the periphery of each lung model is enclosed with a transparent vessel respectively, the bottom of each transparent vessel is connected with an air bag respectively, and the bottom of two air bags connects by cross bar.
During demonstration, press the cross bar of two air bag bottoms, air bag draws high under the effect of power, and the pressure in the transparent vessel reduces, under the effect of external pressure, and the lung model expansion.Cross bar is up pushed away, and the pressure in the transparent vessel increases, and lung model is compressed.The motion conditions of lung is very vivid when repeating above-mentioned action and just can simulate human body respiration.
As further technical scheme, the top of described lung model is provided with hollow tube, the internal communication of hollow tube and lung model.
During demonstration, air enters lung model again by hollow tube earlier, can increase the dynamics of air-flow, strengthens the demonstration effect.
As further technical scheme, the top exit place of described hollow tube is provided with thin bar, and thin bar is fixed on the inwall of hollow tube by elastic webbing.
Thin bar can play the effect of indication airflow direction.
As further technical scheme, be provided with spring between described base and the described cross bar.
When drawing high cross bar, spring compression is unclamped behind the cross bar by the elastic force of spring, and cross bar can move up and down for several times, thereby drives the lung model expansion and shrink for several times, can simulate the motion of human body lung when hurriedly breathing.
In sum, the utlity model has simple in structure, convenient and practical advantage, can simulate the two lungs of human body at intrathoracic breathing state, and simulate effect is better.
