Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a breathing training device. Background Art
[0002] Pursed lip breathing is a rehabilitation training method that is often used in lung function rehabilitation training. Pursed lip breathing is to inhale deeply through the nose to transport air to the lungs when inhaling, and to purse the lips slightly and then slowly exhale the air in the lungs when exhaling. This exercise method can not only exercise the strength of the respiratory muscles and improve the patient's lung function; at the same time, it can counteract the positive end-expiratory pressure and avoid the collapse of the small airways at the end of exhalation, which helps to increase the tidal volume of exhalation, thereby improving the patient's type II respiratory failure.
[0003] At present, when patients perform pursed lip breathing for the first time, the existing pursed lip breathing only relies on the patients' self-control and switching between the nose and mouth for inhalation and exhalation. Patients with slow reaction and poor memory (such as elderly patients) are prone to forgetting to exhale through the mouth after inhaling through the nose and continue to exhale through the nose; or they are prone to forgetting to inhale through the nose after exhaling through the mouth and continue to inhale through the mouth, thereby failing to achieve the purpose of training lung function through pursed lip breathing.

In addition, the terms "first", "second", "third", etc. are only used for descriptive distinction and cannot be understood as indicating or implying relative importance.
[0023] The following will be combined with Figures 1 to 2 to describe this utility model in detail.
[0024] Embodiment:
[0025] A breathing training device, in some embodiments, such as Figures 1 to 2 As shown, it includes a first shell, an exhalation channel is provided inside the first shell, and a one-way exhalation mechanism is provided inside the exhalation channel; a second shell is provided on the top of the first shell, an inhalation channel is provided inside the second shell, and a one-way inhalation mechanism with a ventilation direction opposite to that of the one-way exhalation mechanism is provided in the inhalation channel; an exhalation connection mechanism matching the patient's mouth is provided on one side of the first shell; an inhalation connection mechanism matching the patient's nasal cavity is provided on the side of the second shell close to the exhalation connection mechanism, and the inhalation connection mechanism is connected to the inhalation channel.
[0026] When in use, the patient lifts the first shell and holds it on the patient's face, places the exhalation connection mechanism on the patient's mouth, and connects the inhalation connection mechanism to the patient's nasal cavity. When performing lip-pursed breathing training, the one-way inhalation mechanism allows the patient to let the external air enter the human body through the nasal cavity through the inhalation channel, but cannot exhale the gas through the nasal cavity. The one-way exhalation mechanism allows the patient to exhale the gas in the lungs from the human body through the exhalation channel through the mouth, but cannot inhale the gas through the mouth, thereby effectively solving the technical problem that patients with slow reaction and poor memory are prone to forget to exhale through the mouth after inhaling through the nose, but continue to exhale through the nose; or are prone to forget to inhale through the nose after exhaling through the mouth, but continue to inhale through the mouth.
[0027] In some embodiments, Figures 1 to 2 As shown, the one-way exhalation mechanism includes a first accommodating groove symmetrically arranged inside the exhalation channel; the first accommodating groove is hinged with a first elastic valve at a position close to the exhalation connection mechanism; the first elastic valve is connected to one end of a first spring on a side away from the exhalation connection mechanism; the other end of the first spring is connected to the first accommodating groove; a first blocking plate is also fixedly connected to the inside of the exhalation channel, and the first blocking plate cooperates with the first elastic valve.
[0028] When the patient exhales, gas is exhaled from the patient's mouth into the exhalation channel, and then pushes the first elastic valve to rotate, so that the end of the first elastic valve is separated from the first blocking plate, thereby opening the exhalation channel to allow the gas to be exhaled; when the patient inhales through the nasal cavity or attempts to inhale with the mouth, the first elastic valve recovers under the action of the first spring, so that the first elastic valve re-matches with the first blocking plate, thereby forming a closed channel.
[0029] In some embodiments, Figures 1 to 2As shown, the end of the first elastic valve is bent, and the bending direction is towards the direction close to the exhalation connection mechanism; on the side away from the exhalation connection mechanism, the first baffle is provided with a first elastic groove matching the end of the first elastic valve.
[0030] The end of the first elastic valve is bent. When the exhalation channel is closed, the bent end of the first elastic valve can fall into the first elastic groove, increasing the sealing effect of the channel closure.
[0031] In some embodiments, as Figures 1 to 2 shown, the one-way exhalation mechanism includes a flared nozzle fixedly connected to the first housing and extending outward.
[0032] Through the flared nozzle, it can completely fit the outer side of the patient's mouth, making the patient more comfortable during use.
[0033] In some embodiments, as Figures 1 to 2 shown, the outer edge of the flared nozzle is provided with an elastic pad.
[0034] The elastic pad increases the comfort of the patient during use and also increases the sealing performance of the flared nozzle.
[0035] In some embodiments, as Figures 1 to 2 shown, the inner wall of the exhalation channel gradually extends and tightens in the direction away from the exhalation connection mechanism, so that the diameter of the air outlet of the first housing is smaller than the diameter of the flared nozzle.
[0036] When the patient exhales, the exhalation channel can simulate the exhalation form of puckering the lips, assisting the patient in performing lip-puckering breathing training.
[0037] In some embodiments, as Figures 1 to 2 shown, the one-way inhalation mechanism includes second accommodation grooves symmetrically arranged inside the inhalation channel; a second elastic valve is hinged at a position away from the inhalation connection mechanism in the second accommodation groove; one end of the second elastic valve is connected to one end of a second spring; the other end of the second spring is connected to the second accommodation groove; a second baffle is also fixedly connected inside the inhalation channel, and the second baffle cooperates with the second elastic valve.
[0038] When the patient inhales, the gas enters the inhalation channel from the outside, then pushes the second elastic valve to rotate, so that the end of the second elastic valve disengages from the second baffle, and then the inhalation channel is opened to inhale the gas; when the patient exhales through the mouth or attempts to exhale through the nasal cavity, the second elastic valve returns under the action of the second spring, so that the second elastic valve re-cooperates with the second baffle, thereby forming a channel closure.
[0039] In some embodiments, as Figures 1 to 2 shown, the end of the second elastic valve is bent, and the bending direction is away from the suction connection mechanism; on the side close to the suction connection mechanism, the second baffle is provided with a second elastic groove matching the end of the second elastic valve.
[0040] The end of the second elastic valve is bent so that when the suction channel is closed, the bent end of the second elastic valve can be inserted into the second elastic groove, increasing the sealing effect of the channel closure.
[0041] In some embodiments, as Figures 1 to 2 shown, the suction connection mechanism includes two ventilation hoses communicating with the suction channel and fixedly connected to the second housing, and the outer ends of the ventilation hoses are sleeved with sealing plugs matching the patient's nasal cavity.
[0042] During specific use, the sealing plug is inserted into the nasal cavity, and gas is inhaled into the lungs through the ventilation hoses.
[0043] In some other embodiments, different from the above embodiments, as Figures 1 to 2 shown, filter meshes are provided in both the air outlet and the intake port of the suction channel to prevent dust from entering the device and facilitate subsequent cleaning work.
[0044] The working principle of this device:
[0045] By setting up a one-way ventilation mechanism (one-way suction mechanism and one-way exhalation mechanism), when the patient performs pursed-lip breathing training, external air can only be inhaled in the following order: the outside world - the suction channel - the suction connection mechanism - the nasal cavity - the lungs into the human body, and when exhaling, the gas can only be discharged from the human body in the following order: the lungs - the oral cavity - the exhalation connection mechanism - the exhalation channel - the outside world, thus effectively preventing the patient from exhaling gas through the nose; or inhaling through the mouth, thereby avoiding the inability to achieve the purpose of training lung function through pursed-lip breathing.
[0046] The above-described embodiments only represent the specific implementation manners of the present application, and the description is relatively specific and detailed, but it should not be construed as a limitation on the protection scope of the present application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the technical solution of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application.
