Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a bidirectional vibration-resistant ventilation device that combines positive and negative pressure. Background Technology

[0002] The thoracic cavity (including but not limited to the lungs, bronchi, organs, and respiratory muscles) is a vital site for gas exchange between the internal and external systems of the human body and plays a crucial role in supporting normal physiological metabolism. Newborns, the elderly, and patients with respiratory, nervous, or endocrine disorders, those undergoing surgery or anesthesia, or those who are bedridden for extended periods are prone to decreased cardiopulmonary function, weakened respiratory muscles, weak cough, excessive sputum production, and difficulty expectorating. These conditions can easily lead to airway obstruction, obstructive pulmonary disease, aspiration pneumonia, respiratory failure, acute respiratory distress syndrome, and respiratory muscle weakness, increasing the medical burden on society and patients, and in severe cases, endangering life. Positive and negative pressure bidirectional vibration resistance ventilation devices are important medical instruments used for expelling secretions, providing positive and negative pressure ventilation, and training respiratory muscles.

[0003] In the prior art, such as Chinese invention patent CN213667333U entitled "A Respiratory Sputum Clearing Device," a respiratory sputum clearing device is disclosed. The device includes a body comprising a mouthpiece, a lower body, an upper body, and a top cover, all hollow and connected sequentially. A funnel-shaped mounting seat is engaged between the lower and upper bodies, and a vibrating ball rests within the mounting seat. The bottom end of the side wall of the top cover has an annular connecting groove arranged circumferentially along the side wall, which is threaded onto the top of the upper body. Several air outlets are evenly distributed at the top end of the top cover. A spring is fixedly connected to the inner side wall of the top of the top cover, with its bottom end extending above the vibrating ball. This invention has a reasonable structural design, allowing for adjustment of the blowing resistance to accommodate individual differences among users.

[0004] In the prior art, these conventionally used portable sputum expectorators generally include a main body, a mouthpiece located on one side for the user to bite and exhale, and a vibrating tool located inside the main body that vibrates as exhaled air flows in. When in use, the user bites the mouthpiece and exhales forcefully into the main body. As the exhaled air passes through the inside of the main body, it acts on the vibrating tool, causing the vibrating tool to vibrate. This, in turn, acts on the viscous material attached to the user's respiratory tract, loosening it and making it easier to expel.

[0005] Currently, sputum suction devices on the market have a simple structure and are only used for sputum removal. However, users of sputum suction devices often need to undergo breathing training while receiving sputum suction treatment. This means that users need to use sputum suction devices and breathing training devices separately to achieve the therapeutic effect and improve the recovery process, which not only leads to an excessively long treatment course but also makes them inconvenient to use. Summary of the Invention

[0006] This invention addresses the shortcomings of existing technologies by providing a bidirectional vibration-resistant ventilation device that combines positive and negative pressure. During exhalation and inhalation, vibration waves are generated. The vibration dislodges sputum while training the inspiratory muscles, especially the diaphragm, achieving the effects of airway clearance and respiratory muscle training.

[0007] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a bidirectional vibration-resistant ventilation device with both positive and negative pressure, comprising a housing with a working chamber inside, an air vent connected to the working chamber on the housing, a mouthpiece for the user to exhale and inhale connected to the air vent, two working ends of the housing respectively provided with gas flow structures that connect the working chamber to the outside, and an oscillation structure that can generate vibration during use is provided near the gas flow structure.

[0008] In the above technical solution, the working end includes an exhalation working end and an inhalation working end. The air inlet is located on the side of the housing and forms a three-way structure with the exhalation working end and the inhalation working end, which makes it more convenient to use and the layout is more scientific and reasonable.

[0009] In the above technical solution, the oscillation structure includes a positive pressure oscillation component disposed near the expiratory working end and a negative pressure oscillation component disposed near the inspiratory working end.

[0010] In the above technical solution, the positive pressure oscillation component includes a positive pressure oscillation base and a positive pressure oscillation bead disposed in the cavity of the positive pressure oscillation base. Under positive pressure, the positive pressure oscillation bead moves in the cavity and then oscillates the air. The oscillating air can resonate with the user's lungs, effectively loosening the phlegm that has fallen off the tracheal wall.

[0011] In the above technical solution, the bottom of the positive pressure oscillation base is provided with an exhalation hole that matches the arc surface of the positive pressure oscillation bead. In the initial state, the exhalation channel is closed by the arc surface of the oscillation bead.

[0012] In the above technical solution, the negative pressure oscillation component includes a negative pressure oscillation upper seat, a negative pressure oscillation lower seat, and a negative pressure oscillation bead disposed in an oscillation cavity formed by the negative pressure oscillation upper seat and the negative pressure oscillation lower seat. The negative pressure oscillation bead moves within the cavity and oscillates the air. The vibration generated by negative pressure inhalation can dislodge sputum in the airway while training the inspiratory muscles.

[0013] In the above technical solution, the top of the cavity of the upper negative pressure oscillator and the bottom of the cavity of the lower negative pressure oscillator are respectively provided with air intake holes that match the arc surface of the negative pressure oscillating bead. In the initial state, the air intake channel is closed by the arc surface of the oscillating bead.

[0014] In the above technical solution, the gas flow structure includes an expiratory regulating component disposed on the expiratory working end and an inspiratory regulating component disposed on the inspiratory working end.

[0015] In the above technical solution, the expiratory regulation component includes an expiratory connector for connecting to the housing of the expiratory working end and an expiratory regulation cover disposed on the expiratory connector and capable of regulating the air volume, which can adjust the blowing resistance according to the individual differences of the user to meet personalized treatment needs.

[0016] In the above technical solution, the structure of the inspiratory adjustment component is consistent with that of the expiratory adjustment component, including an inspiratory connection seat for connecting to the housing of the inspiratory working end and an inspiratory adjustment cover disposed on the inspiratory connection seat and capable of adjusting the ventilation volume, which can adjust the inspiratory resistance according to the individual differences of the user to meet personalized treatment needs.

[0017] Compared with existing technologies, the present invention has the following beneficial effects: By using a positive pressure oscillation component located near the expiratory working end and a negative pressure oscillation component located near the inspiratory working end, vibration waves are generated during exhalation, causing sputum to fall off. Simultaneously, vibration is also generated during inhalation, which can dislodge sputum in the airway while training the inspiratory muscles, especially the diaphragm, achieving the effect of airway clearance. This integrates respiratory training and sputum clearance functions into one, breaking the limitation of traditional single-function devices. Users no longer need to use multiple devices to loosen sputum during respiratory training, greatly improving the efficiency of the device and the user experience, and accelerating the recovery process. Furthermore, by setting an expiratory adjustment component on the expiratory working end and an inspiratory adjustment component on the inspiratory working end, the resistance to blowing or inhaling can be adjusted according to individual user differences, meeting personalized treatment needs and improving the effectiveness of sputum clearance and respiratory training.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] The following description is intended to disclose the invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

[0026] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "left," "right," "front," "rear," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this invention.

[0027] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0028] See Figures 1 to 5 The device is a bidirectional vibration-resistant ventilation device with both positive and negative pressure. It includes a housing 1 and a working chamber 10 inside the housing 1. Preferably, the housing 1 is a cylindrical structure. Of course, it is not limited to this structure. The cylindrical structure is mainly convenient to carry and the processing technology is simpler, which helps to reduce manufacturing costs and improve market competitiveness. Therefore, the shape of the housing 1 can be adapted to meet actual usage needs.

[0029] A vent 11 is provided on the side wall of the housing 1, which allows the working chamber 10 to be connected to the outside. The upper working end and the lower working end of the housing 1 are both open, serving as the exhalation working end 12 and the inhalation working end 13, respectively. In this way, the vent 11, the exhalation working end 12, and the inhalation working end 13 form a three-way structure.

[0030] A mouthpiece 2 is connected to the air vent 11 for the user to exhale and inhale. Of course, the mouthpiece 2 has a channel that communicates with the air vent 11, allowing the user to exhale gas into the working chamber 10 or inhale gas from the working chamber 10.

[0031] The positive pressure oscillation component 3, located near the exhalation working end 12, is mainly used to oscillate the air when the user exhales. The oscillating airflow can resonate with the user's lungs, thereby loosening the phlegm that has fallen off the tracheal wall. The user can then expel the phlegm from the respiratory tract by coughing or other means.

[0032] The positive pressure oscillation assembly 3 includes a positive pressure oscillation base 31 and a positive pressure oscillation bead 32. The positive pressure oscillation base 31 is a conical funnel-shaped structure with two openings, one large and one small. The top opening is larger and the bottom opening is smaller, which matches the exhalation hole of the positive pressure oscillation bead 32. The diameter of the exhalation hole opening is smaller than the diameter of the oscillation bead 32 to prevent the oscillation bead 32 from falling out of the exhalation hole. This cavity forms an oscillation chamber. The positive pressure oscillation bead 32 is placed in the oscillation chamber. Under normal conditions, the bottom surface of the positive pressure oscillation bead 32 always remains engaged with the bottom exhalation hole, blocking the connection between the exhalation working end 12 and the working chamber 10.

[0033] Correspondingly, the negative pressure oscillation component 4, which is located near the inhalation working end 13, is mainly used to oscillate the air when the user performs inhalation. The oscillating airflow can dislodge phlegm in the airway and train the inspiratory muscles at the same time, thereby achieving the effect of breathing training.

[0034] The negative pressure oscillation assembly 4 includes a negative pressure oscillation upper seat 41, a negative pressure oscillation lower seat 42, and a negative pressure oscillation bead 43. Similarly, the structure of the negative pressure oscillation upper seat 41 and the negative pressure oscillation lower seat 42 is the same as that of the positive pressure oscillation base 31, both being conical funnel-shaped structures. The conical funnel-shaped structure has two opening ends, one large and one small. The large opening end of the negative pressure oscillation upper seat 41 fits into the large opening end of the negative pressure oscillation lower seat 42. The negative pressure oscillation bead 43 is set in the negative pressure oscillation cavity formed by the cooperation of the negative pressure oscillation upper seat 41 and the negative pressure oscillation lower seat 42. Of course, when the sputum suction device is always placed in a vertical position, the negative pressure oscillation upper seat 41 can be omitted. However, in use, people usually store it horizontally. In order to prevent the negative pressure oscillation bead 43 from rolling out of the negative pressure oscillation cavity, the negative pressure oscillation upper seat 41 is provided. The small opening at the top of the cavity of the negative pressure oscillation upper seat 41 is used for the airflow of inhalation. It is worth mentioning that, under normal conditions, the negative pressure oscillating bead 43 always keeps its bottom surface fitted with the small opening, i.e., the air intake hole, of the negative pressure oscillating lower seat 42, thus blocking the connection between the air intake working end 13 and the working chamber 10.

[0035] In order to adjust the blowing or inhalation resistance according to individual user differences, meet personalized treatment needs, and improve the effectiveness of sputum expectoration and breathing training, the exhalation working end of the housing 1 is provided with an exhalation adjustment component 5, and the inhalation working end of the housing 1 is provided with an inhalation adjustment component 6.

[0036] The exhalation adjustment assembly 5 includes an exhalation connector 51 and an exhalation adjustment cover 52. The exhalation connector 51 is provided with a connecting structure for connecting to the housing of the exhalation working end 12. The exhalation adjustment cover 52 is movably disposed on the upper working end of the exhalation connector 51 and can rotate coaxially with respect to the upper working end of the exhalation connector 51. Of course, both the exhalation connector 51 and the exhalation adjustment cover 52 are provided with an exhalation hole 511 and an exhalation adjustment hole 521. In order to facilitate users to adjust the exhalation resistance more intuitively, an exhalation resistance mark 512 is provided on the exhalation connector 51.

[0037] The structure of the inhalation adjustment component 6 is the same as that of the exhalation adjustment component 5, including an inhalation connection seat 61 and an inhalation adjustment cover 62. The inhalation connection seat 61 is also provided with a connection structure that connects to the housing of the inhalation working end 13. The inhalation adjustment cover 62 is rotatably mounted on the inhalation connection seat 61. The inhalation resistance is adjusted by adjusting the opening of the inhalation hole and the inhalation adjustment hole. It is simpler and more convenient than the traditional structure. Of course, the inhalation resistance mark 611 is also provided on the inhalation connection seat 61.

[0038] When using this invention, the user holds the expectorant with the expiratory working end 12 facing upwards and the inhalation working end 13 facing downwards, as shown below. Figure 4As shown, at this time, the positive pressure oscillating bead 32 keeps its bottom surface fitted with the bottom exhalation hole, blocking the connection between the exhalation working end 12 and the working chamber 10, and the negative pressure oscillating bead 43 keeps its bottom surface fitted with the small opening, i.e. the inhalation hole, of the negative pressure oscillating lower seat 42, blocking the connection between the inhalation working end 13 and the working chamber 10.

[0039] The user holds the mouthpiece 2 in their mouth and blows air into the working chamber 10 through the mouthpiece 2 channel. The positive pressure oscillating bead 32 generates an upward thrust, rising and disengaging from the exhalation port. After blowing is completed, the positive pressure oscillating bead 32 falls back down under its own weight. The positive pressure oscillating bead 32 vibrates as it rises and falls continuously. The oscillating airflow can resonate with the user's lungs, thereby loosening the phlegm that has fallen off the tracheal wall. The user can then expel the phlegm from the respiratory tract by coughing or other means. In this state, the negative pressure oscillating bead 43 always keeps its bottom surface engaged with the small opening, i.e., the inhalation port, of the negative pressure oscillating lower seat 42, blocking the connection between the inhalation working end 13 and the working chamber 10.

[0040] During breathing training, the user holds mouthpiece 2 in their mouth and inhales through mouthpiece 2. Under negative pressure, negative pressure oscillating beads 43 detach from the inhalation port. After inhalation, negative pressure oscillating beads 43 fall downwards under their own weight. The negative pressure oscillating beads 43 also vibrate as they rise and fall continuously, allowing the user to train their inspiratory muscles, especially the diaphragm, while simultaneously treating sputum expectoration.

[0041] When users need to adjust the blowing or inhalation resistance according to individual differences, they only need to refer to the blowing resistance mark 512 and the inhalation resistance mark 611, rotate the exhalation adjustment cover 52 or the inhalation adjustment cover 62, and adjust the opening between the exhalation port 511 and the exhalation adjustment port 521 or the opening between the inhalation port and the inhalation adjustment port to adjust the inhalation resistance.

[0042] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments, and any modifications or variations of the embodiments of the present invention may be made without departing from the stated principles.
