Abstract
The utility model discloses an air embolism and first aid position demonstration heart model, include by the heart shell model, on, inferior vena cava model, pulmonary artery model and aorta model constitute, establish 4 cardiac chambers in its heart shell model, valve between 2 atrioventricular, on, inferior vena cava model, pulmonary artery model and aorta model are respectively in the right atrium, right ventricle and left ventricle link to each other, on the representative, the pipeline entrance of inferior vena cava all establishes a silica gel and seals, and respectively have a tubule to pass the gas injection tubule of the direct right ventricle of atrioventricular valve, the pipeline export of representing pulmonary artery also has a sealed little cap of silica gel of enduring the puncture. Because the utility model can visually and vividly demonstrate the process of air embolism in the heart, the requirement of medical teaching and practice is met.
Description
Technical field
The utility model is medical college and the clinical instruments used for education of using, and is specially a kind of air embolism demonstration and first aid
Model.
Background technology
Air embolism is a kind of serious and urgent reaction in the infusion reaction.As the air capacity that enters is large, and air is at right ventricle internal congestion pulmonary artery entrance, blood can not be entered carry out the gas exchange in the lung, causes the body severe depletion of oxygen and dies suddenly, and must give immediately the first aid process of left side Trendelenburg position.In teaching practice, one group of signal picture commonly used illustrates process and principle, emergency treatment method and the purpose of air embolism, and more abstract, the student only can memorize mechanically, and the processing position of disease is a lot of in the medical science, does not thoroughly understand very easily note and obscures.Secondly, some patient can mismatch the propaganda and education of correlation theory transfusion clinically, causes unnecessary accident.Existing cardiac module has mostly just imitated the formation of each organ of heart, and fails to reflect that air embolism causes the situation of change of heart inside.Therefore, setting up the teaching mode of a process that can help student and patient can visual pattern ground to understand air embolism, principle and clinical emergency treatment method, is the needs of medical teaching and practice.
Summary of the invention
Needs in existing medical teaching and the clinical practice the utility model proposes a kind of teaching mode that can effectively show air embolism process and principle, emergency treatment method and purpose.
The utility model is realized by following manner: a kind of air embolism and first aid position demonstration cardiac module, comprise by heart shell model, on, the inferior caval vein model, pulmonary artery model and sustainer model form, establish 4 chambers of the heart in its cardiac shell mould type, valve between 2 chambers, on, the inferior caval vein model, pulmonary artery model and sustainer model are respectively at the atrium dextrum, right ventricle links to each other with left ventricle, and externally indicate the direct of travel of blood in pipeline with red blue arrow respectively, it is characterized in that: in the representative, inferior caval entrance place all establishes silica gel sealing, and respectively have a tubule to pass the gas injection tubule of the through right ventricle of valve between chamber, represent the silica gel sealing small cap that Pulmonic pipe outlet also has a puncture-resistant.
Because the utility model can have been demonstrated the process of heart inner air embolism visual pattern, making the student pass through model imparts knowledge to students always, can produce deep perceptual knowledge to air embolism, thereby the medical science that helps the student firmly to grasp flexibly relevant heart generation air embolism is known, can be reduced Accidental occurrence to simple and clear ground of patient propaganda and education clinically, is the needs of medical teaching and practice.

Fig. 2 is structure schematic diagram of the present utility model.
Specific implementation method
As shown in Figure 1, 2, make the model of heart with the shape of transparent material simulation human heart, and according to the architectural feature of human heart blood vessel each arteriovenous is installed in respectively on the corresponding position.Wherein superior vena cava 6 seals with the capping 7 that the silica gel material is made respectively with the openend of inferior caval vein 8 models, but syringe nipple can penetrate gas injection from capping 7, and the sealing of withdrawing from rear seal-cover 7 can be closed voluntarily.
In superior vena cava 6 and inferior caval vein 8 models, be connected respectively two gas injection tubules 5, the inlet end of gas injection tubule 5 links to each other with the capping 7 of superior vena cava 6, inferior caval vein 8 respectively, the end of gas injection tubule 5 right ventricle 4 that goes directly, gas injection is used when representing air and reaching the approach of right ventricle 4 and demonstration by peripheral vein.Pulmonary artery 1 endpiece that links to each other with right ventricle 4 also has the sealing silica gel small cap 2 of a puncture-resistant.After cardiac module is finished, in model, fill with the red liquid 3 that represents blood.
Behind superior vena cava 4 or inferior caval vein 8 injection air, because air than liquid light, behind the bubble floating, can be assembled at pulmonary artery 1 entrance, form larger bubble, thereby block pulmonary artery 1 entrance---be the air embolism process.Then adopt the first aid position, make bubble floating to right ventricle 4 apex, avoid pulmonary artery 1 entrance.First-aid method and principle when air embolism occurs have so namely been demonstrated.Demonstration is finished, again reply the original body position, bubble is floated again to pulmonary artery 1 entrance (in live body, when bubble floating after right ventricle 4 apex, along with heartthrob, air can be blended together gas foam, gradation enters in the pulmonary artery 1 in a small amount, be absorbed gradually), penetrate the silica gel small cap 2 extraction injecting gas that puncture-resistant is sealed in pulmonary artery 1 inlet end with the minute hand head again.
Claims (1)
1. an air embolism and first aid position demonstration cardiac module, comprise by heart shell model, on, the inferior caval vein model, pulmonary artery model and sustainer model form, establish 4 chambers of the heart in its cardiac shell mould type, valve between 2 chambers, on, the inferior caval vein model, pulmonary artery model and sustainer model are respectively at the atrium dextrum, right ventricle links to each other with left ventricle, and externally indicate the direct of travel of blood in pipeline with red blue arrow respectively, it is characterized in that: in the representative, inferior caval entrance place all establishes silica gel sealing, and respectively have a tubule to pass the gas injection tubule of the through right ventricle of valve between chamber, represent the silica gel sealing small cap that Pulmonic pipe outlet also has a puncture-resistant.
