[0044] Please refer to the following: Figures 1 to 7 The autonomous breathing simulation device provided in the embodiments of this application will now be described.

[0045] An autonomous breathing simulation device includes a fixation plate 10, a lung bag 20, a drive mechanism 30, and a controller (not shown in the figure).

[0046] Specifically, the fixation plate 10 is installed inside the dummy body 40 and located in the thoracic cavity of the dummy body 40, with the fixation plate 10 spaced apart from both the front and rear side walls of the dummy body 40. The lung sac 20 is connected to the side of the fixation plate 10 facing the front side wall.

[0047] The drive mechanism 30 includes a fixed part and a telescopic part that can reciprocate relative to the fixed part in a direction perpendicular to the fixed plate 10. The fixed part is connected to the side of the fixed plate 10 facing the rear side wall, and the telescopic part passes through the fixed plate 10 and is connected to the side wall of the lung sac 20 near the front side wall.

[0048] The controller is electrically connected to the drive mechanism 30 and is used to control the time interval between the reciprocating motion of the fixed part and the travel distance of the telescopic part relative to the fixed part.

[0049] The controller can be set with parameters to simulate various human breathing states as needed. For example, when simulating rapid breathing, the controller controls the fixed part of the drive mechanism 30 to drive the telescopic part to reciprocate within a first time interval. When simulating slow breathing, the controller controls the fixed part of the drive mechanism 30 to drive the telescopic part to reciprocate within a second time interval. The first time interval is shorter than the second time interval.

[0050] Meanwhile, the controller is also used to control the movement stroke of the fixed part of the drive mechanism 30 relative to the telescopic part. For example, when simulating a deep breathing state, the telescopic part moves a first stroke distance relative to the fixed part, and when simulating a normal breathing state, the telescopic part moves a second stroke distance relative to the fixed part, and when simulating a short breathing state, the telescopic part moves a third stroke distance relative to the fixed part. The third stroke distance is smaller than the second stroke distance, and the second stroke distance is smaller than the first stroke distance.

[0051] As needed, the first time interval of the movement of the fixed part driving the telescopic part can be combined with the third stroke interval to simulate a state of rapid and shallow breathing.

[0052] Compared with the prior art, the autonomous breathing simulation device provided in this application includes a fixing plate 10, a lung sac 20, a drive mechanism 30, and a controller. The fixing plate 10 is installed inside the dummy body 40 and located in the thoracic cavity of the dummy body 40, with the fixing plate 10 spaced apart from both the front and rear side walls of the dummy body 40. The lung sac 20 is connected to the side of the fixing plate 10 facing the front side wall. The drive mechanism 30 includes a fixing part and a telescopic part capable of reciprocating relative to the fixing part in a direction perpendicular to the fixing plate 10. The fixing part is connected to the side of the fixing plate 10 facing the rear side wall, and the telescopic part passes through the fixing plate 10 and connects to the side wall of the lung sac 20 near the front side wall. The controller is electrically connected to the drive mechanism 30 and is used to control the time interval for the fixing part to drive the telescopic part to reciprocate and the stroke of the telescopic part relative to the fixing part, so that the lung sac 20 simulates the frequency, depth, and rhythm of breathing.

[0053] In this application, the fixing plate 10 is provided with a first through hole 11, which penetrates the fixing plate 10 in a direction perpendicular to the fixing plate 10. The lung sac 20 is provided with a second through hole 211 on the side wall near the fixing plate 10. The telescopic part passes through the first through hole 11 and then connects to the side wall of the lung sac 20 away from the fixing plate 10.

[0054] Specifically, the lung sac 20 has a first sidewall 21 and a second sidewall 22. The first sidewall 21 is close to and fixed to the fixing plate 10, such as by bonding it to the fixing plate 10. The second sidewall 22 is located on the side of the first sidewall 21 away from the fixing plate 10. A second through hole 211 is located in the first sidewall 21. The telescopic part passes through the first through hole 11 and the second through hole 211 in sequence and then connects to the second sidewall 22. Through the reciprocating movement of the telescopic part, the second sidewall 22 is moved away from or closer to the first sidewall 21, thereby simulating the breathing state of the human body.

[0055] In this application, the autonomous breathing simulator also includes a connecting plate 35.

[0056] Specifically, the connecting plate 35 is connected to the end of the telescopic part away from the fixed part, and the side wall of the lung sac 20 away from the fixed plate 10 is connected to the connecting plate 35. That is, the second side wall 22 is connected to the connecting plate 35, such as by adhesive bonding.

[0057] In one embodiment of this application, the autonomous breathing simulator further includes a clamping plate 36.

[0058] The clamping plate 36 is connected to the end of the telescopic part away from the fixed part, and the side wall of the lung sac 20 away from the fixed plate 10 is clamped between the connecting plate 35 and the clamping plate 36. That is, the second side wall 22 is provided with a third through hole 221, the end of the telescopic part away from the fixed part is accommodated in the third through hole 221, and the part of the second side wall 22 located around the third through hole 221 is clamped in the clamping space between the clamping plate 36 and the connecting plate 35.

[0059] In this application, the autonomous breathing simulator also includes a support member 50.

[0060] Specifically, one end of the support member 50 is connected to the side of the fixation plate 10 away from the lung sac 20, and the other end is connected to the rear side wall, which is used to support the fixation plate 10 inside the thoracic cavity of the dummy body 40. There are multiple support members 50, and multiple support members 50 are arranged at intervals along the circumference of the fixation cover plate.

[0061] Preferably, in this application, the number of support members 50 is four.

[0062] In this application, the autonomous breathing simulator also includes a connecting tube 60.

[0063] One end of the connecting tube 60 is connected to the lung sac 20, and the other end is connected to the oral cavity of the dummy body 40. When the second sidewall 22 is close to the first sidewall 21, the connecting tube 60 is used to expel part of the gas in the lung sac 20 through the oral cavity of the dummy body 40, and when the second sidewall 22 is away from the first sidewall 21, the connecting tube 60 is used to inject gas into the lung sac 20 through the oral cavity of the dummy body 40.

[0064] In one embodiment of this application, the drive mechanism 30 includes a hollow shaft servo motor 31 and a lead screw 32.

[0065] The hollow shaft servo motor 31 is the fixed part of the drive mechanism 30, including a stator and a rotor that rotates relative to the stator. The stator is connected to the side of the fixed plate 10 facing the rear side wall, and the stator is electrically connected to the controller. The rotor is provided with a through hole, and the inner wall of the through hole is provided with a threaded tooth structure.

[0066] The lead screw 32 is the telescopic part of the drive mechanism 30. The lead screw 32 is rotatably connected in the through hole and meshes with the threaded tooth structure. It is used to reciprocate in a direction perpendicular to the fixed plate 10 under the drive of the stator. The connecting plate 35 and the clamping plate 36 are both rotatably connected to the end of the lead screw 32 away from the hollow shaft servo motor 31.

[0067] The controller is used to adjust the speed, direction, and rotation time of the hollow shaft servo motor 31 within its rated power according to the required breathing simulation state. For example, when simulating a state of rapid and shallow breathing, the controller controls the hollow shaft servo motor 31 to rotate forward at a first speed in a first sub-time interval and reverse at a first speed in a second sub-time interval, wherein the first time interval includes the first sub-time interval and the second sub-time interval, and the first sub-time interval and the second sub-time interval are equal; when simulating a normal breathing state, the controller controls the hollow shaft servo motor 31 to rotate forward at a second speed in a third sub-time interval and reverse at a second speed in a fourth sub-time interval, wherein the second time interval includes the third sub-time interval and the fourth sub-time interval, and the third sub-time interval and the fourth sub-time interval are equal, and the first speed is less than or equal to the second speed.

[0068] In another embodiment of this application, such as Figure 7 As shown, the drive mechanism 30 includes a cylinder body 33 and a telescopic rod 34.

[0069] Specifically, the fixed part of the drive mechanism 30 is a cylinder body 33, which is connected to the side of the fixed plate 10 facing the rear side wall. The cylinder body 33 is connected to the air pump, and the air pump is electrically connected to the controller.

[0070] The telescopic part of the fixed part is a telescopic rod 34, which is slidably connected to the cylinder body 33 and reciprocates relative to the cylinder body 33 in a direction perpendicular to the fixed plate 10. The connecting plate 35 and the clamping plate 36 are connected to the end of the telescopic rod 34 away from the cylinder body 33.

[0071] The control mechanism adjusts the flow rate of gas injected into the cylinder body 33 by the air pump, causing the cylinder body 33 to drive the telescopic rod 34 to reciprocate within the cylinder body 33. For example, when simulating a state of rapid and shallow breathing, the controller controls the cylinder body 33 to extend the telescopic rod 34 by a first stroke distance in a first sub-time interval and retract it by a first stroke distance in a second sub-time interval. The first time interval includes the first sub-time interval and the second sub-time interval, and the first sub-time interval and the second sub-time interval are equal. When simulating a normal breathing state, the controller controls the cylinder body 33 to extend the telescopic rod 34 by a second stroke distance in a third sub-time interval and retract it by a second stroke distance in a fourth sub-time interval. The second time interval includes the third sub-time interval and the fourth sub-time interval, and the third sub-time interval and the fourth sub-time interval are equal. The first stroke distance is less than the second stroke distance.

[0072] In this application, the autonomous breathing simulation device also includes a first limiting member 37 and a second limiting member 38.

[0073] The connecting plate 35 and the clamping plate 36 are located between the first limiting member 37 and the second limiting member 38; the first limiting member 37 is located on the side of the connecting plate 35 away from the clamping plate 36, and the second limiting member 38 is located on the side of the clamping plate 36 away from the connecting plate 35.

[0074] Specifically, both the first limiting member 37 and the second limiting member 38 are retaining springs. The lead screw 32 or the telescopic rod 34 is provided with a first retaining groove and a second retaining groove. The first limiting member 37 is engaged in the first retaining groove, and the second limiting member 38 is engaged in the second retaining groove.

[0075] The above are merely preferred embodiments of this application and are not intended to limit this application.
