Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of medical auxiliary equipment, and particularly relates to a self-adjusting breathing training device. BACKGROUND

[0002] The breathing training device can effectively train the respiratory muscle group of the human body by increasing the impedance, increase the endurance and strength of the inspiratory muscle and expiratory muscle, improve the cardiopulmonary function of the human body, and improve the vital capacity, and therefore has a wide application in many fields.

[0003] Especially in the medical field and the sports field, the breathing training device can play a significant effect for patients with impaired lung function and athletes who need to strengthen the respiratory muscle group. Similarly, in daily life, the breathing training can enhance the physical fitness, enhance the immunity, and obtain a better physique.

[0004] At present, the breathing training devices on the market generally adopt a pure mechanical structure, and it is difficult to achieve the effect of self-control of the exhalation and inhalation training synchronization and precise control of the impedance size. In addition, the impedance size changes in the training process, the set training load is fuzzy and inaccurate, and it is difficult to achieve the post-training feedback and the modification of the training plan.

[0005] For example, the publication number "CN212214512U" discloses a "breathing training device for pneumology department", which comprises a breathing training inner cylinder, a breathing training outer cylinder is screw-connected to the top of the breathing training inner cylinder, a breathing training top-tightening assembly is slidably arranged in the breathing training inner cylinder and the breathing training outer cylinder, a breathing mask assembly is fixedly arranged on one side of the bottom cylinder of the breathing training outer cylinder through an air pipe, and the patient blows air into the breathing training inner cylinder through the breathing mask assembly and the air pipe to push the breathing training sealing disc upward. When the breathing training sealing disc passes the air release hole, the pressure in the breathing training inner cylinder decreases, and the breathing training sealing disc is automatically reset under the action of the top-tightening spring. In this way, the breathing training process of the patient is realized. The breathing training inner cylinder and the breathing training outer cylinder are screw-connected, the relative position between the breathing training inner cylinder and the breathing training outer cylinder is adjusted to adjust the tightening force of the top-tightening spring on the breathing training sealing disc, so as to realize the adjustment of the breathing training intensity. However, in actual application, the spring is repeatedly reset, the elastic force of the spring changes with the compression degree of the spring, which causes the change of the impedance received by the patient during the training process, and it is not easy to adjust according to the rehabilitation training intensity of the patient, and the inspiratory rehabilitation training cannot be met. SUMMARY

[0006] In view of the problems of the prior art mentioned in the background that the impedance size changes in the training process, the intensity is not easy to adjust, and the inhalation rehabilitation training cannot be met, the present application provides a self-adjusting breathing training device, which can accurately and quantitatively control the size of the impedance, so that the load of the patient in the training process is within a controllable range, facilitating the analysis and adjustment of the training plan for the patient in the later stage, and the air path channel can be adjusted and adapted according to the training intensity of the patient to obtain different impedances, and the inhalation muscle can be trained, and one breathing cycle can simultaneously train the exhalation muscle and the inhalation muscle.

[0007] The second application object of the present application is to enable the patient to individually increase the impedance of the exhalation or inhalation process without detaching from the breathing training device during one breathing process, to individually relieve the impedance of the relative breathing process, and to achieve the effect of unilateral training.

[0008] The third application object of the present application is to enable quick switching between the increase of the exhalation impedance and the increase of the inhalation impedance.

[0009] To achieve the above-mentioned object, the present application adopts the following technical solutions.

[0010] A self-adjusting breathing trainer includes an air control valve sleeve, the air control valve sleeve having an oblique sidewall, the air control valve sleeve having a breathing interface and an atmospheric interface, a movable valve plug being disposed between the breathing interface and the atmospheric interface, and an air passage being formed between the edge of the movable valve plug and the oblique sidewall. The respiratory impedance setting in this invention is achieved through an airway channel. A movable valve plug abuts against the inclined side. The two ends of the control valve sleeve are the breathing interface and the atmospheric interface, respectively. When the movable valve plug moves, a gap is created between it and the inclined side; this gap forms the airway channel. At this time, the airway channel connects the breathing interface and the atmospheric interface. The breathing interface connects to the patient's airway, and the atmospheric interface connects to the outside air. Because the airway channel is created through the gap between the movable valve plug and the air valve sleeve, the tubing area of ​​the airway channel is much smaller than that of the breathing interface and the atmospheric interface. Therefore, due to the throttling effect of the orifice, if the gas flow rate through the airway channel remains constant, when the flow area of ​​the airway channel decreases, the pressure difference between the atmospheric interface and the breathing interface will increase; conversely, when the flow area increases, the pressure difference between the atmospheric interface and the breathing interface will decrease. Impedance is generated whether gas is transported from the breathing interface to the atmospheric interface or vice versa. Therefore, expiratory and inspiratory muscles can be trained during the same breathing process. The movable valve can be manually controlled, for example, by connecting a control motor or adjusting its movement through the sliding and fixing of a slider. Thus, the size of the airway remains constant during training. The patient is affected by the impedance at the beginning of the breathing process, and the magnitude of the impedance is the same as the ideal set value. This allows the ideal load to be applied throughout the entire contraction and relaxation process of the muscles, unlike spring impedance, where the resistance force generated in the early stage of spring compression is small, resulting in some time when the training is not up to standard. The solution of this invention makes the patient's training plan formulation and feedback more intuitive and convenient.

The flaps are hinged at the edge of the movable valve plug, and the other end of the flaps can abut against the inclined side wall under the action of the airflow. The gaps are left between the adjacent flaps, and the area of the gaps gradually increases with the increase of the unfolding degree of the flaps. With the forward and backward movement of the movable valve plug, the air passage between the movable valve plug and the inclined side wall is changed. The size of the air passage is the unfoldable range of the flaps. When the air passage becomes larger, the unfolding degree of the flaps under the influence of the airflow becomes larger, so that the area of the gaps between the flaps becomes larger, thereby controlling the size of the resistance. When the airflow in the opposite direction is generated, the flaps retract, the air passage is not hindered, and the resistance decreases. In this scheme, the actual size of the air passage is controlled by the gaps between the flaps. Therefore, it is necessary to control the area of the original air passage to always maintain a larger area, so that the resistance is smaller when the reverse flow passes. Further, when reversing is needed, the driving motor drives the movable valve plug to retreat to a position where the flaps can be fully unfolded. At this time, the flaps can freely swing without abutting against the inclined side wall. The flaps are limited on the same side of the movable valve plug by inhaling or exhaling. After the driving motor returns, the flaps complete the reversing. The reversing process of this scheme is simple and fast, and the air passage is divided by the flaps. The airflow flows out from the gaps between the separated flaps, and the resistance effect is better.

[0022] (2) By the small hole throttling principle, the exhalation and inhalation can both generate resistance, and the adjustment can be made for different patients, and the application range is wider.

[0023] (3) The driving motor is controlled by the control panel, the size of the air passage is adjusted according to the exhalation frequency of the patient, the resistance during exhalation or inhalation can be increased alone, and targeted rehabilitation training is generated.

[0057] Embodiment 4:

[0058] As Figure 8As shown, unlike example 1, in this embodiment, a movable rod 3 is arranged inside the driving rod 211, the movable rod 3 is connected with the inside of the driving rod 211 through a reset spring 33, the movable rod 3 is provided with a conversion groove 31 at the end, a spring plunger 32 is arranged on the connecting center 121, the spring plunger 32 can be movable into the conversion groove 31 under no external force, the spring plunger 32 is not clamped with the conversion groove 31 in the initial state, the elastic force of the reset spring 33 is far greater than that of the spring plunger 32, at this time, the spring plunger 32 is extruded away from the circle center protrusion by the movable rod 3, the inner segment 122 can abut on one side thereof, when exhale-inhale conversion is needed, the driving motor drives the driving rod 211 to retreat, so that the end of the movable rod 3 is abutted with the first connecting barrel, the driving motor continues to move, the reset spring 33 is stretched, at this time, the movable rod 3 is stationary, the movable valve plug 12 is always retreated until clamped with the conversion groove 31 on the movable rod 3, the spring plunger 32 is retracted, the inner segment 122 loses the abutment point and can swing freely on both sides of the movable valve plug 12, at this time, inhale or exhale through the breathing interface 112, so that the inner segment 122 is all limited on the required side, the reset driving motor is reset, the movable rod 3 is retracted under the driving of the reset spring 33, the spring plunger 32 is separated from the conversion groove 31, and the protrusion is re-established, at this time, the inner segment 122 completes the conversion and can abut on the other side of the spring plunger 32, in order to make the inner segment 122 easy to change the orientation when exhale or inhale, the movable range of the hinge is arranged between 15°-165° and there is an included angle between the center axis, this scheme can realize quick internal valve switching according to the user demand, to adapt to different training needs.

[0059] Example 5:

[0060] As Figure 9 , 10As shown, unlike Embodiment 1, in this embodiment, a plurality of outwardly extending pieces 123 are hinged at the edge of the movable valve plug 12, and the end of the outwardly extending piece 123 away from the movable valve plug 12 can abut against the inclined side wall 111. An outwardly extending piece 123 is hinged to the edge of the movable valve plug 12. The other end of the outwardly extending piece 123 can abut against the inclined sidewall 111 under the action of airflow. A gap exists between adjacent outwardly extending pieces 123. As the degree of extension of the outwardly extending piece 123 increases, the area of ​​the gap also gradually increases. With the back-and-forth movement of the movable valve plug 12, the air passage 13 between the movable valve plug 12 and the inclined sidewall 111 changes. The size of the air passage 13 is the deployable range of the outwardly extending piece 123. When the air passage 13 becomes larger, the degree of extension of the outwardly extending piece 123 under the influence of airflow increases, thereby increasing the area of ​​the gap between the outwardly extending pieces 123, thus controlling the resistance. When a reverse airflow is generated, the outwardly extending piece 123 retracts, the air passage 13 is unobstructed, and the resistance decreases. In this design, the actual airflow width is controlled by the gap between the outward-spreading plates 123. Therefore, it is necessary to maintain a relatively large area of ​​the original airflow channel 13 to minimize resistance during reverse flow. Furthermore, when reversal is required, the drive motor moves the movable valve plug 12 back to a position where the outward-spreading plates 123 can be fully extended. At this point, the outward-spreading plates 123 can swing freely without contacting the inclined sidewall 111. By inhaling or exhaling, the outward-spreading plates 123 are confined to the same side of the movable valve plug 12. After the drive motor returns to its original position, the outward-spreading plates 123 complete the reversal. This design offers a simple and quick reversal process, and the airflow channel 13 is divided by the outward-spreading plates 123, allowing airflow to exit through the gaps between the multiple separated outward-spreading plates 123, resulting in a better applied resistance effect.

[0061] Example 6:

[0062] like Figure 11 As shown, unlike Embodiment 1, in this embodiment, a spring 19 is sleeved on the first guide cylinder 161. One end of the spring 19 abuts against the first connecting seat 16, and the other end abuts against the movable valve plug 12. When the drive source 212 stops working, the drive rod 211 loses its power restriction. At this time, the restoring force of the spring 19 becomes the new drive source 212 for the movable valve plug 12, driving the movable valve plug 12 to abut against the inclined side wall 111 for sealing and isolation. This facilitates better fixation of the position of the movable valve plug 12 when the drive source 212 is restarted. A baffle 2112 is provided at the end of the drive rod 211 near the movable valve plug 12. One end of the spring 19 abuts against the baffle 2112 instead of the movable valve plug 12, avoiding the elastic force abutting against the movable valve plug 12 and causing it to detach from the drive rod 211.
