Abstract
The utility model discloses a demonstration model of heat dilation caused by pressure overload, and relates to a medical teaching aid. The demonstration model of heart dilation caused by pressure overload caused by the pressure overload mainly comprises an aorta model, an arteriae pulmonalis model, an aorta outflow tract model, an arteriae pulmonalis outflow tract model, a left ventricle model, a right ventricle model, a valvula bicuspidalis model, a valvula tricuspidalis model and ventricular septum models, and is characterized in that the aorta model is communicated with the aorta outflow tract model and communicated to the left ventricle model at last, the left ventricle model is formed by the sealing of a left ventricular wall model, the ventricular septum model and the valvula bicuspidalis model, the arteriae pulmonalis model is communicated with the arteiar pulmonalis outflow tract model and communicated to the right ventricle model at last, the right ventricle model is formed by the sealing of a right ventricular wall model, the ventricular septum model and the valvula tricuspidalis model, and inflatable balls are respectively connected with openings of the aorta model and the arteriae pulmonails model. The demonstration model of heart dilation caused by the pressure overload is suitable for majors such as clinical medicine, nursing care, anesthesia, intensive care unit (ICU) of medical colleges and universities to be used as intuitive demonstration teaching aid when hypertensive disease and chronic pulmonary hypertension are explained.
Description
Technical field
The utility model relates to a kind of medical teaching and uses teaching aid, particularly the overweight cardiac enlargement demonstrating model that causes of pressure load.
Background technology
In the medical pathologies teaching process; When telling about " hypertensive cardiopathy " and " cor pulmonale "; Though some complementary teaching aids that have sample, teaching material picture and the teaching of many bodies to provide; But do not have dynamic demonstration technical ability,, can not see the visual stimulus effect that is occurred in kind with observing though multimedia can provide a small amount of animation demonstration.
Summary of the invention
The utility model content:
The purpose of the utility model is the deficiency that lacks the demonstrating model teaching aid of " the overweight cardiac enlargement that causes of pressure load " to existing, provides a kind of lively, vivid long-term hypertension of probing into to cause that left ventricle dilatation and pulmonary hypertension cause the illustrative model of right ventricle expansion.
The technical scheme that realizes the utility model is: the overweight cardiac enlargement demonstrating model that causes of a kind of pressure load; Mainly form by sustainer model, pulmonary artery model, sustainer efferent tract model, pulmonary artery efferent tract model, left ventricle model, right ventricle model, bicuspid valve model, tricuspid valve model and interventricular septum model; It is characterized in that: sustainer model and sustainer efferent tract are connected; Lead to the left ventricle model at last, the left ventricle model is formed by left ventricular wall model, interventricular septum model and bicuspid valve model encapsulates; Pulmonary artery model and pulmonary artery efferent tract are connected, and lead to the right ventricle model at last, and the right ventricle model is formed by right ventricle wall model, interventricular septum model and tricuspid valve model encapsulates, and inflatable ball connects sustainer model and pulmonary artery model opening respectively.Said sustainer model and pulmonary artery model opening part are equipped with breather cheek valve.Cardiac module is inflatable elastomeric material.
The utility model can visual pattern demonstration go out hypertension and cause that left ventricle dilatation and pulmonary hypertension cause the pathologic process of right ventricle expansion, thereby can excite student's learning interest, stay deep study impression.

Embodiment:
The specific embodiment of the utility model that provides through Figure of description 1 below further describes its structure; Accompanying drawing 1 is the utility model structural representation; Referring to accompanying drawing 1; The overweight cardiac enlargement demonstrating model that causes of pressure load; Mainly form by sustainer model 3, pulmonary artery model 5, sustainer efferent tract model 12, pulmonary artery efferent tract model 6, left ventricle model 15, right ventricle model 9, bicuspid valve model 13, tricuspid valve model 7 and interventricular septum model 18; Sustainer model 3 is connected with sustainer efferent tract model 12, leads to left ventricle model 15 at last through sustainer efferent tract opening 14, and left ventricle model 15 is formed by left ventricular wall model 16, interventricular septum model 18 and 13 sealings of bicuspid valve model; Pulmonary artery model 5 is connected with pulmonary artery efferent tract model 6; Lead to right ventricle model 9 at last through pulmonary artery efferent tract opening 8; Right ventricle model 9 is formed by right ventricle wall model 17, interventricular septum model 18 and 7 sealings of tricuspid valve model, and inflatable ball 1 connects sustainer model opening 2 and pulmonary artery model opening 10 respectively.Said sustainer model and pulmonary artery model opening are equipped with breather cheek valve 19.Cardiac module as shown in the figure, that the utility model relates in order to increase and the anatomical cardiac similarity, is provided with atrium sinistrum model 11 and atrium dextrum model 4 above cardiac module.
During use; When simulation hypertension; Inflatable ball 1 pressurization inflation makes air pass through unidirectional gas admission valve 19 and imports sustainer model 3, goes forward side by side into sustainer efferent tract model 12; Arrive left ventricle model 15 through sustainer efferent tract opening 14, thereby simulation ejection impedance increase causing left ventricle bears bigger pressure load and makes 15 expansions of left ventricle model when shrinking.
When the simulated lung arterial hypertension; Through inflatable ball 1 pressurization inflation; Make air pass through unidirectional gas admission valve 19 and import pulmonary artery model 5; And get into pulmonary artery efferent tract model 6, arrive right ventricle model 9 through pulmonary artery efferent tract opening 8, thereby simulation ejection impedance increase causing right ventricle bears bigger pressure load and makes 9 expansions of right ventricle model when shrinking.
From the above, the utility model can be intuitively, demonstrate out the overweight pathologic process that causes cardiac enlargement of pressure load visually.
