Specific embodiment
For the effect for further illustrating mode adopted by the present invention and acquirement, below in conjunction with attached drawing 1-3 to this hair
Bright technical solution is understood and is fully described by.
A kind of CPR heart external chest compression theory teaching tool as shown in Figure 1 is by manikin 1 and to place
Thoracic cavity simulator, heart simulator, brain simulator and arteria carotis simulator composition inside the manikin 1.
Press device 2 as shown in Figure 2, i.e., the described thoracic cavity simulator are by pressing plate 21, fixed plate 22,231 groups of spring
At the spring 231 includes spring upper end 2311 and lower spring end 2312, and the pressing plate 21 is fixed with spring upper end 2311 to be connected
It connects, the fixed plate 22 is fixedly connected with lower spring end 2312.
As shown in figure 3, the heart simulator is by liquid reserve tank 3, leakage fluid dram 34, push plate 32, connecting rod 31 and locating piece
33 compositions, 31 upper end of connecting rod are fixedly connected with pressing plate 21, and lower end is fixedly connected with the push plate 32,3 He of liquid reserve tank
To be slidably connected between push plate 32, liquid reserve tank 3 is provided with the leakage fluid dram 34, the locating piece close to brain simulator side
33 are fixedly connected with 3 inner wall of liquid reserve tank.
As shown in Figure 1, the brain simulator is by glass shell 51 and the gelatin being placed on inside the glass shell 51
Model 5 forms.
As shown in Figure 1, the arteria carotis simulator is a delivery pipe 4, the row of described delivery pipe 4 one end and liquid reserve tank 3
Liquid mouth 34 connects, and the other end is connect with gelatin model 5.
In a wherein embodiment, between horizontal plane where horizontal plane where 33 upper end of locating piece and 32 lower end of push plate
Vertical range is 6cm, because pressing amplitude at least 5cm when external chest compression, but be should be avoided more than 6cm, being more than this amplitude may
There is complication, endangers patient health.
In a wherein embodiment, four springs 231 are compressed spring, and effect is that blood is made to complete a mould
Self-return is carried out after quasi- CPR cardiac compression.
In a wherein embodiment, the gelatin mold 5, inside is equipped with the road You Wang structure, for simulating inside brain
Blood vessel；Glass shell 51 is for simulating human body skull；Glue connection is used between gelatin model 5 and glass shell 51.
In a wherein embodiment, the external carotid artery simulator is the delivery pipe 4 that internal diameter is 5mm, is made of plastics,
To transmission experiment fluid, for simulating the external carotid artery of human body connection heart and brain.
In a wherein embodiment, the Experimental Flowing Object solute is edible haematochrome, and solvent is water, for simulating human body
Blood.
Application method of the invention are as follows: manikin 1 is lain on training station, presses pressing plate 21, pressing plate downwards
21 drive connecting rods 31, and connecting rod 31 pushes push plate 32 along 3 inner wall slide downward of liquid reserve tank, oppress along liquid reserve tank Experimental Flowing Object from
Leakage fluid dram 34 flows to delivery pipe 4, and Experimental Flowing Object flows into gelatin model intranet road structure through delivery pipe 4；When pressure amplitude is pressed in push plate 32
When degree reaches 6cm, because the blocking of locating piece 33 can not continue to decline, no longer continue to press to pressing plate 21 at this time；Spring 231 because
Deformation occurs for stress, forces pressing plate 21 to drive push plate 32 to move upwards perpendicular to horizontal plane through connecting rod 31, liquid reserve tank 3
Middle formation low-pressure area, so that the Experimental Flowing Object in gelatin model 5 be made to flow back.The above are the primary complete CPR hearts of simulation
Pressing process.
During pressing, pressing amplitude and compression frequency can be intuitively clearly observed for the shadow of brain blood supply
Ring: shallow by pressing through, frequency is excessively slow, and blood can not reach brain；Pressing amplitude is excessive, can oppress other organs, cause to human body
Injury.Whole process is very clear, and teenager and children is facilitated to understand principle, quickly grasps the first aid of CPR cardiac compression
Skill.
Finally, it should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention, rather than its limitations；Although
Present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: it still may be used
To modify to technical solution documented by previous embodiment or equivalent replacement of some of the technical features；And
These are modified or replaceed, the spirit and model of technical solution of the embodiment of the present invention that it does not separate the essence of the corresponding technical solution
It encloses.
