Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a breathing simulation device. Background Technology

[0002] Monitoring physical and mental well-being during flight becomes particularly important. Currently, wearable physiological monitoring devices are widely used to monitor an individual's physical and mental state during flight; therefore, evaluating the monitoring quality of these devices is crucial.

[0003] Existing technologies typically utilize respiratory simulators to simulate respiratory movements in order to evaluate wearable physiological monitoring devices. However, these simulators primarily mimic breathing by driving the diaphragm, resulting in insignificant chest cavity contour fluctuations and failing to realistically simulate the expansion and contraction of the chest cavity during respiration. Consequently, wearable physiological monitoring devices often struggle to accurately receive respiratory movement signals, thus reducing the accuracy of the assessment. Utility Model Content

[0004] Based on the above analysis, the present invention aims to provide a breathing simulation device to solve the problem that existing breathing simulation devices are insufficient in simulating the contour of the chest cavity and are unable to realistically reproduce the expansion and contraction of the chest cavity during human breathing.

[0005] The objective of this utility model is mainly achieved through the following technical solutions:

[0006] A breathing simulation device, installed inside the chest cavity of a dummy, is used to simulate the expansion and contraction of the chest cavity during human respiration. It includes a base, a limiting guide assembly, a push plate, a push rod, an eccentric connector, and a motor. One end of the limiting guide assembly is fixedly connected to the base, and the other end is fixedly connected to the push plate. The limiting guide assembly guides and restricts the push plate to move only towards or away from the base. The push plate is fixedly connected to the ribcage of the dummy. One end of the push rod is connected to the eccentric connector, and the other end is connected to the push plate. The motor is mounted on the base, and the eccentric connector is connected to the output shaft of the motor. The motor controls the rotation of the eccentric connector, which in turn drives the push plate to reciprocate towards or away from the base via the push rod, thereby driving the contour of the dummy's chest cavity to rise and fall, thus simulating the expansion and contraction of the chest cavity during human respiration.

[0007] Furthermore, it also includes an adjuster, which includes a slider and a lead screw. The slider is mounted in a guide groove on the eccentric connector and can slide within the guide groove. The slider is hinged to a push rod and is sleeved on the lead screw. By rotating the lead screw, the slider can be driven to slide along the axis of the lead screw within the guide groove, thereby adjusting the distance between the slider and the output shaft of the motor.

[0008] Furthermore, the regulator also includes a worm gear and a worm. The worm gear is fixedly connected to one end of the lead screw. The worm is mounted on an eccentric connector and meshes with the worm gear. By rotating the worm, the worm gear can be driven to rotate, thereby driving the lead screw to rotate.

[0009] Furthermore, the limiting guide assembly includes a limiting sleeve and a guide post.

[0010] Furthermore, the guide post is installed inside the limiting sleeve and can slide along the axis of the limiting sleeve.

[0011] Furthermore, the limiting sleeve is provided with a limiting groove, which extends along the axis of the limiting sleeve.

[0012] Furthermore, the guide post is provided with a limiting guide rail, which extends along the axis of the guide post.

[0013] Furthermore, the limiting guide rail can slide within the limiting sleeve, and through the cooperation of the limiting groove and the limiting guide rail, the circumferential rotation of the guide post around its own axis can be restricted.

[0014] Furthermore, the eccentric connector is an eccentric wheel.

[0015] Furthermore, the motor is a stepper motor.

[0016] The technical solution of this utility model can achieve at least one of the following effects:

[0017] (1) This utility model provides a breathing simulation device, including a base, a limiting guide component, a push plate, a push rod, an eccentric connector, and a motor. One end of the limiting guide component is fixedly connected to the base, and the other end is fixedly connected to the push plate. The limiting guide component is used to guide and restrict the push plate to move only towards or away from the base. The push plate is fixedly connected to the chest ribs of the dummy. One end of the push rod is connected to the eccentric connector, and the other end is connected to the push plate. The motor is mounted on the base, and the eccentric connector is connected to the output shaft of the motor. The motor controls the rotation of the eccentric connector, thereby driving the push plate to reciprocate towards or away from the base through the push rod, thereby driving the dummy's chest cavity contour to rise and fall, and thus simulating the expansion and contraction of the chest cavity during human respiration. This directly simulates the rise and fall of the chest cavity contour, and the chest cavity contour rise and fall effect is significant, realistically reproducing the dynamic changes of the chest cavity during human respiration. This provides accurate respiratory motion signals for wearable physiological monitoring devices, thereby significantly improving the accuracy of wearable physiological monitoring device assessment.

[0018] (2) The breathing simulation device of this utility model also includes an adjuster, which includes a slider and a lead screw. The slider is installed in the guide groove on the eccentric connector and can slide in the guide groove. The slider is hinged to the push rod. The lead screw is mounted in the guide groove and can rotate. The slider is sleeved on the lead screw. By rotating the lead screw, the slider can be driven to slide along the axis of the lead screw in the guide groove, thereby adjusting the distance between the slider 71 and the output shaft of the motor 6, thereby controlling the amplitude of the push plate moving closer to or away from the base, thereby simulating the expansion and contraction amplitude of the chest cavity under different breathing conditions, and realizing the simulation of different breathing amplitudes.

[0027] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0028] Example 1

[0029] A specific embodiment of this utility model discloses a breathing simulation device, installed inside the chest cavity of a dummy, used to simulate the expansion and contraction of the chest cavity during human respiration, such as... Figure 1 As shown, the device includes a base 1, a limiting guide assembly 2, a push plate 3, a push rod 4, an eccentric connector 5, and a motor 6. The base 1 is installed inside the dummy's chest cavity. One end of the limiting guide assembly 2 is fixedly connected to the base 1, and the other end is fixedly connected to the push plate 3. The limiting guide assembly 2 guides and restricts the push plate 3 to move only towards or away from the base 1. The push plate 3 is fixedly connected to the dummy's chest ribs. One end of the push rod 4 is connected to the eccentric connector 5, and the other end is connected to the push plate 3. The motor 6 is mounted on the base 1, and the eccentric connector 5 is connected to the motor 6. The output shaft is connected, and the eccentric connector 5 is rotated by the motor 6, which in turn drives the push plate 3 to reciprocate towards or away from the base 1 via the push rod 4, thereby driving the dummy's chest cavity contour to rise and fall, and thus simulating the expansion and contraction of the chest cavity during human respiration. Compared with the prior art, this embodiment directly simulates the rise and fall of the chest cavity contour, and the chest cavity contour rise and fall effect is significant, realistically reproducing the dynamic changes of the chest cavity during human respiration. This provides accurate respiratory motion signals for wearable physiological monitoring devices, thereby significantly improving the accuracy of wearable physiological monitoring device assessment.

[0030] Preferably, the limiting guide assembly 2 includes a limiting sleeve 21 and a guide post 22. The guide post 22 is installed inside the limiting sleeve 21 and can slide along the axis of the limiting sleeve 21.

[0031] Preferably, such as Figure 2 As shown, the limiting sleeve 21 is provided with a limiting groove 211, which extends along the axis of the limiting sleeve 21; the guide post 22 is provided with a limiting guide rail 221, which extends along the axis of the guide post 22 and can slide on the limiting sleeve 21; through the cooperation of the limiting groove 211 and the limiting guide rail 221, the circumferential rotation of the guide post 22 around its own axis can be effectively restricted, ensuring the stability and accuracy of the entire mechanism's movement.

[0032] Preferably, the eccentric connector 5 is an eccentric wheel.

[0033] Example 2

[0034] Example 2 is a further improvement based on Example 1, such as... Figure 3 As shown, the breathing simulation device also includes an regulator 7, which is mounted on the eccentric connector 5 and connected to the push rod 4. The regulator 7 is used to control the distance between the connection point of the push rod 4 and the eccentric connector 5 and the output shaft of the motor 6, thereby controlling the amplitude of the push plate 3 moving closer to or further away from the base 1, thus simulating the expansion and contraction amplitude of the chest cavity under different breathing conditions and realizing the simulation of different breathing amplitudes.

[0035] Preferably, such as Figure 4 As shown, the eccentric connector 5 is provided with a guide groove 51; the adjuster 7 includes a slider 71 and a lead screw 72. The slider 71 is installed in the guide groove 51 and can slide in the guide groove 51; the slider 71 is hinged to the push rod 4; the lead screw 72 is mounted in the guide groove 51 and can rotate; the slider 71 is sleeved on the lead screw 72. By rotating the lead screw 72, the slider 71 can be driven to slide along the axis of the lead screw 72 in the guide groove 51, thereby adjusting the distance between the slider and the output shaft of the motor 6, and thus controlling the amplitude of the adjustment push plate 3 moving closer to or further away from the base 1, thereby simulating the expansion and contraction amplitude of the chest cavity under different breathing conditions.

[0036] The adjuster 7 also includes a worm gear 73 and a worm 74. The worm gear 73 is fixedly connected to one end of the lead screw 72. The worm 74 is mounted on the eccentric connector 5 and meshes with the worm gear 73. By rotating the worm 74, the worm gear 73 can be driven to rotate more easily, thereby driving the slider 71 to slide along the axis of the lead screw 72 in the guide groove 51, thereby adjusting the distance between the slider 71 and the output shaft of the motor 6, and realizing the control of the adjustment push plate 3 moving closer to or further away from the base 1. In addition, the worm gear 73 and the worm 74 form a worm gear mechanism. Through the self-locking function of the worm gear mechanism, the adjusted slider 71 can be locked to ensure that the distance between the adjusted slider 71 and the output shaft of the motor 6 remains unchanged.

[0037] Example 3

[0038] Example 3 is a further improvement based on Example 1 or Example 2. The motor 6 is a stepper motor. By controlling the rotation speed of the motor 6, the expansion and contraction frequency of the dummy's chest can be controlled, thereby simulating different breathing frequencies of a human.

[0039] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
