Abstract

The utility model relates to a demonstration model of a simulative air embolism which belongs to a medical teaching device, particularly a teaching aid for demonstrating an air embolism. The utility model is mainly composed of a power pump, a right atrium model, a right ventricle model, a pulmonary artery model, a pulmonary artery branched model, a vena model and a reservoir. The simulative system of pulmonary circulation is formed. The utility model has simple structure, convenient operation, visual teaching and lucid teaching.

Description

Simulated air embolism demonstrating model

The utility model belongs to medical teaching equipment, particularly demonstrates the teaching aid of air embolism.

In traditional air embolism experimental teaching, all be to adopt rabbit to make sample, that is: in the auricular vein of rabbit, inject air, treat that it after death cuts the thoracic cavity open, take out heart and place the vessel that water is housed, cut the visible gas of heart again open and emit, illustrate that with this cause of the death of rabbit is that air embolism causes.This experiment can not be seen the process of air embolus operation and the cardinal principle of air embolism, and operation is relatively more difficult and need certain skill, and the economy expenditure of experimental teaching is also bigger.

The purpose of this utility model provides a kind of simulated air embolism demonstrating model, simple in structure, easy to operate, visual and understandable, the use economy of imparting knowledge to students.

The realization the technical solution of the utility model is: mainly by power pump, the atrium dextrum model, the right ventricle model, the pulmonary artery model, the pulmonary artery branch model, vein model and reservoir are formed this device, power pump is communicated with the atrium dextrum model, on the model of atrium dextrum exhausr port is housed, between atrium dextrum model and right ventricle model retaining valve is housed, one termination reservoir of vein model, another termination atrium dextrum model and interface are equipped with retaining valve, on the vein model, also be connected to the air introducing port, pulmonary artery model one termination right ventricle model, another termination pulmonary artery branch model leads to reservoir at last.

Below, the specific embodiment of the present utility model by Figure of description provides is further described its structure.

Fig. 1 is a structural representation of the present utility model.

Referring to accompanying drawing, the power pump 12 of this device is communicated with atrium dextrum model 9, exhausr port 6 is housed on the atrium dextrum model 9,4 on atrium dextrum model 9 and right ventricle model are equipped with retaining valve 5, one termination reservoir 13 of vein model 10, another termination atrium dextrum model 9 and interface are equipped with retaining valve 8, also are connected to air introducing port 11 on vein model 10, pulmonary artery model 7 one termination right ventricle models 4, another termination pulmonary artery branch model 3 leads to reservoir 13 at last.In this device, atrium dextrum model 9, right ventricle model 4, pulmonary artery model 7 and pulmonary artery branch model 3 adopt transparent material, and power pump 12 adopts quantitative reciprocating pump, and pulmonary artery branch model 3 is fixed on the lung model 2, and the top simulation alveolar 1 that also is connected with.

During use, the mouth of pipe insertion of vein model 10 is equipped with in the reservoir 13 of red liquid, close air introducing port 11 and exhausr port 6, with the liquid of power pump 12 extraction capacities, open exhausr port 6 again, make atrium dextrum model 9 and right ventricle model 4 fulls of liquid discharge air, close exhausr port 6 again, at this moment the or else disconnected liquid that sucks of power pump 12 can just perform the compile mouthful discharge of all surplus airs from pulmonary artery branch model 3 demonstration and prepare; Close under the situation at air introducing port 11 and exhausr port 6, start quantitative reciprocating power pump 12, the mouth that compiles of pulmonary artery branch model 3 is discharged a quantitative liquid, can intuitively show the pulmonary circulation of normal condition; When opening air introducing port 11, air can suck in the pipe of vein model 10 with liquid, enter atrium dextrum model 9, right ventricle model 4, pulmonary artery model 7 and pulmonary artery branch model 3 again, pulmonary artery branch model 3 places thinner at caliber form air embolism, with flowing of blocking-up liquid, be also shown in gas this moment and be compressed situation with exapnsion with liquid mobile in the heart of simulation, also visible liquid flow is hindered, output quantity no longer is the situation of constant basis.

From technique scheme of the present utility model, this apparatus structure is simple, easy to operate, teaching is visual and understandable, it is economical to use.
