The embodiment of the utility model provides a chest compression training model, which can determine a compression position and output position information corresponding to the compression position by triggering a circuit board in a compression positioning device through a compression switch piece, has a more real structure, can bear larger compression force and improves the accuracy of compression training operation.

Some embodiments of the utility model are described in detail below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1 to 7, an embodiment of the utility model provides a chest compression training model, which includes a simulated skin layer 10, a cushioning layer 20 and a compression positioning device 30 arranged from top to bottom.

Wherein the opposite bottom surface of the cushioning layer 20 is provided with a receiving cavity 22 for receiving the pressing and positioning device 30, and the cushioning layer 20 is used for cushioning the force generated at the pressing position in the simulated skin layer 10. At least one push switch piece 311 is arranged on the opposite top surface of the push positioning device 30, and when the push switch piece 311 receives the force transmitted by the buffer layer 20, the circuit board 32 in the push positioning device 30 can be triggered, so that the push position can be detected through the circuit board 32, and the position information corresponding to the push position can be output.

Specifically, as shown in fig. 1 to 3, the shape of the simulated skin layer 10 is the same as the shape of a real human chest, which can make the structure of the chest compression training model more real.

In an embodiment of the present invention, the simulated skin layer 10 may be made of a thermoplastic elastomer, such as silicone. The thermoplastic elastomer is a thermoplastic elastomer material, and has the characteristics of high strength, high resilience and the like. The thickness of the simulated skin layer 10 may be 2mm to 4mm, or other thickness values.

When the simulated skin layer 10 using the thermoplastic elastomer is pressed or tapped during the chest compression training operation, the simulated skin layer 10 has the chest compression feeling or tapping feeling of a real human body. In addition, the simulated skin layer 10 may dampen some of the force when subjected to the force.

The force referred to in the embodiments of the present invention may include, but is not limited to, a pressing force and a tapping force.

In some embodiments, as shown in fig. 3, the opposite back side of the simulated skin layer 10 is provided with at least one connector 11, the connector 11 being adapted to be removably connected to the cushioning layer 20.

As shown in fig. 4, the cushioning layer 20 is provided with at least one first through hole 21, the first through hole 21 being connectable with the connection head 11 for connecting the simulated skin layer 10 with the cushioning layer 20.

Specifically, the buffer layer 20 is in a dome shape and is used for simulating the tissue morphology of the human chest, so that the structure of the chest compression training model can be more real.

Specifically, the buffer layer 20 is made of a foamed material. The foaming material is a substance that can be gasified to generate bubbles in the substance and then becomes a porous substance. In the embodiment of the present invention, the buffer layer 20 may be a soft foam.

The flexible foam material is produced by physically foaming or cross-linking a raw material such as plastic or rubber with an auxiliary material such as a catalyst, a foam stabilizer, and a foaming agent to thereby form a large amount of fine foam, increase in volume, and decrease in density in the plastic or rubber. The soft foaming material has light weight and good softness, and has the functions of buffering, sound absorption, shock absorption, heat preservation, filtration and the like.

The buffer layer 20 can buffer the force generated by the compression position in the simulated skin layer 10, so that the chest compression training model can bear larger force; it is avoided that the push positioning device 30 is subjected to excessive force, which may cause damage to the push positioning device 30.

As shown in fig. 5, fig. 5 is a schematic view of the structure of the opposite bottom surface of the buffer layer 20. Receiving cavities 22 are provided on opposite bottom surfaces of cushioning layer 20. The receiving cavity 22 is used for receiving the pressing and positioning device 30, and can prevent the pressing and positioning device 30 from shifting during the pressing and training operation.

In some embodiments, the receiving cavity 22 is surrounded by a support frame 23, and the support frame 23 is used for supporting the cushioning layer 10 and dispersing the force applied to the cushioning layer 10.

Specifically, the supporting frame 23 includes a supporting frame main body 231 surrounding the accommodating cavity 22, and a plurality of supporting frame branches 232 extending away from the accommodating cavity 22.

Wherein, at least one screw hole 233 is provided in the support frame main body 231, and the screw hole 233 is used for fixing the pressing and positioning device 30 on the opposite bottom surface of the buffer layer 20. For example, threaded holes 233 can mate with fasteners to secure the compression positioning device 30 to the opposite bottom surface of cushioning layer 20.

It should be noted that the supporting frame main body 231 and the supporting frame branches 232 are used for dispersing the force applied to the cushioning layer 20 to prevent the cushioning layer 20 and the pressing and positioning device 30 from deforming. For example, the support frame branches 232 are used to distribute the pressing force and/or the tapping force applied to the cushioning layer 20, so that the chest compression training model can be subjected to a larger pressing force and/or tapping force.

As shown in fig. 7, fig. 7 is an exploded view of the pressing and positioning device 30.

Specifically, the push positioning device 30 includes a position switch panel 31 and a support base 33 in addition to the circuit board 32. The circuit board 32 is disposed between the position switch panel 31 and the supporting base 33, and the supporting base 33 is connected to the position switch panel 31 by a snap-fit connection.

Specifically, the peripheral edge of the support base 33 is snap-connected to the peripheral edge of the position switch panel 31. It should be noted that the notches on the peripheral edge of the position switch panel 31 face outward, and the notches on the peripheral edge of the support base 33 face inward, so that the support base 33 can be connected with the position switch panel 31 in a snap-fit manner. The support base 33 may limit the four edges of the position switch panel 31 from being outwardly biased when the position switch panel 31 is subjected to a force conducted by the buffer layer 20.

Please refer to fig. 8 to 11. As shown in fig. 8, the push switch piece 311 is provided in the position switch panel 31, and the push switch piece 311 comes into contact with the circuit board 32 when receiving a force transmitted from the buffer layer.

Specifically, the diameter of the contact switch 3213 is greater than the diameter of the second cylinder 3111-b. It should be noted that the contact switch 3213 is a hollow cylinder and the second cylinder 3111-b is a spherical surface; the first flexible circuit layer 3211 may be deformed into a spherical surface and touch the contact switch 3213 in the second flexible circuit layer 3212 by the second cylinder 3111-b abutting the first flexible circuit layer 3211 during the process of the second cylinder 3111-b triggering the contact switch 3213; the shearing force between the second cylinder 3111-b and the first flexible circuit layer 3211 can be reduced, the concentration of fatigue points at the shearing position can be reduced, and the lifetime of the flexible circuit board 321 can be prolonged.
