Furthermore, the terms "first," "second," "third," and the like are used merely to distinguish between descriptions and should not be construed as indicating or implying relative importance.
The present utility model is described in detail below with reference to fig. 1 to 2.
Examples:
In some embodiments, as shown in fig. 1-2, the respiratory training device comprises a first shell, wherein an exhalation channel is arranged in the first shell in a penetrating manner, a one-way exhalation mechanism is arranged in the exhalation channel, a second shell is arranged at the top of the first shell, an inhalation channel is arranged in the second shell in a penetrating manner, a one-way inhalation mechanism opposite to the one-way exhalation mechanism in ventilation direction is arranged in the inhalation channel, an exhalation connecting mechanism matched with a mouth of a patient is arranged on one side of the first shell, an inhalation connecting mechanism matched with a nasal cavity of the patient is arranged on one side of the second shell, close to the exhalation connecting mechanism, of the second shell, and the inhalation connecting mechanism is communicated with the inhalation channel.
In particular use, the patient holds the first housing in position on the patient's face during use and places the exhalation connecting mechanism in the patient's mouth and connects the inhalation connecting mechanism with the patient's nasal cavity. When the lip-contracting respiratory training is carried out, the patient can only enter external air into a human body through the nasal cavity through the respiratory channel and can not exhale air through the nasal cavity, and the patient can only exhale air from the human body through the respiratory channel through the oral cavity and can not inhale air through the oral cavity through the unidirectional respiratory mechanism, so that the technical problems that the patient with relatively low reaction force and relatively poor memory can forget to use the mouth to exhale air after inhaling through the nose and continue to use the nose to exhale air or can forget to use the nose to inhale after exhaling through the mouth and continue to inhale through the mouth are effectively solved.
In some embodiments, as shown in fig. 1-2, the unidirectional exhalation mechanism includes a first accommodation groove symmetrically disposed inside the exhalation channel, the first accommodation groove is hinged with a first elastic valve at a position close to the exhalation connection mechanism, the first elastic valve is connected with one end of a first spring at one side far away from the exhalation connection mechanism, the other end of the first spring is connected with the first accommodation groove, a first blocking plate is fixedly connected inside the exhalation channel, and the first blocking plate is matched with the first elastic valve.
When the patient breathes out, the air breathes out from the oral cavity of the patient and enters the exhaling channel, then the first elastic valve is pushed to rotate, the end part of the first elastic valve is separated from the first blocking plate, the exhaling channel is opened, the air exhaling channel is further opened, when the patient breathes in through the nasal cavity or breathes out with the mouth, the first elastic valve returns under the action of the first spring, and the first elastic valve is matched with the first blocking plate again, so that the channel is closed.
In some embodiments, as shown in fig. 1-2, the end portion of the first elastic valve is bent, the bending direction of the end portion faces to the direction close to the expiration connecting mechanism, and the first blocking plate is provided with a first elastic groove matched with the end portion of the first elastic valve on one side away from the expiration connecting mechanism.
The first elastic valve end is bent, and when the expiration channel is closed, the bent first elastic valve end can be sunk into the first elastic groove, so that the sealing effect of channel closure is improved.
In some embodiments, as shown in fig. 1-2, the unidirectional exhalation mechanism includes a horn mouth fixedly connected with the first housing and extending outward.
The loudspeaker mouth can be completely matched with the outer side of the mouth of a patient, so that the patient is more comfortable when using the loudspeaker mouth.
In some embodiments, as shown in fig. 1-2, an elastic pad is disposed at an outer edge of the horn mouth.
The comfort of the patient is increased through the elastic pad, and the sealing performance of the horn mouth is improved.
In some embodiments, as shown in fig. 1-2, the inner wall of the exhalation passageway extends gradually and tightens along the direction away from the exhalation connection mechanism, so that the caliber of the air outlet of the first housing is smaller than the caliber of the horn mouth.
When the patient exhales, the exhaled channel can simulate the exhaled form of the contracted lip to assist the patient to carry out the contracted lip breathing training.
In some embodiments, as shown in fig. 1-2, the unidirectional air suction mechanism comprises a second accommodating groove symmetrically arranged in the air suction channel, a second elastic valve is hinged to the second accommodating groove at a position far away from the air suction connecting mechanism, the second elastic valve is connected with one end of a second spring at one side close to the air suction connecting mechanism, the other end of the second spring is connected with the second accommodating groove, a second blocking plate is fixedly connected in the air suction channel, and the second blocking plate is matched with the second elastic valve.
When the patient exhales through the oral cavity or the delusions and exhales through the nasal cavity, the second elastic valve returns under the action of the second spring, so that the second elastic valve is matched with the second blocking plate again, and the channel is closed.
In some embodiments, as shown in fig. 1-2, the end portion of the second elastic valve is bent, the bending direction of the second elastic valve faces away from the air suction connection mechanism, and a second elastic groove matched with the end portion of the second elastic valve is formed in one side, close to the air suction connection mechanism, of the second blocking plate.
The end part of the second elastic valve is bent, and when the air suction channel is closed, the bent end part of the second elastic valve can be sunk into the second elastic groove, so that the sealing effect of channel closure is improved.
In some embodiments, as shown in fig. 1-2, the inhalation connection mechanism includes two ventilation hoses which are communicated with the inhalation channel and fixedly connected with the second shell, and sealing plugs matched with nasal cavities of patients are sleeved at outer ends of the ventilation hoses.
When the nasal cavity-sealing device is particularly used, the sealing plug is plugged into the nasal cavity, and air is inhaled into the lung through the ventilation hose.
In other embodiments, unlike the above embodiments, as shown in fig. 1-2, the air outlet and the air inlet of the air suction channel are both provided with filter screens, so that dust is prevented from entering the device, and the subsequent cleaning operation is convenient.
The working principle of the device is as follows:
By arranging the unidirectional ventilation mechanism (unidirectional inhalation mechanism and unidirectional exhalation mechanism), when a patient performs lip-contracting breathing training, external air can only enter the human body from the outside to the inhalation channel, the inhalation connecting mechanism, the nasal cavity and the lung, and when the patient exhales, air can only be discharged from the human body from the lung to the oral cavity, the exhalation connecting mechanism, the exhalation channel and the outside in the order, so that the patient is effectively prevented from exhaling air by the nose, or the patient can be prevented from inhaling by the mouth, so that the purpose of training the lung function by lip-contracting breathing can be avoided.

It should be noted that it is possible for a person skilled in the art to make several variants and modifications without departing from the technical idea of the application, which fall within the scope of protection of the application.
