Description

Technical Field

[0001] The invention relates to a breathing training device for infants. Background Art

[0002] Inhalation is an active process. Active contraction expands the chest cavity and reduces the pressure in the lungs. When the pressure in the lungs is lower than atmospheric pressure, air is inhaled into the lungs. Normal inhalation is handled by the diaphragm and the external intercostal muscles. When the diaphragm and the external intercostal muscles contract, the diaphragm is positioned downward and the chest cavity moves outward and upward at the same time, increasing the volume of the chest cavity. The mechanism of exhalation is that the pressure in the lungs is greater than the atmospheric pressure. Normal exhalation does not involve muscle contraction. When the diaphragm and the external intercostal muscles relax, the chest cavity becomes smaller, the pressure in the lungs increases, and air is exhaled from the body. However, when external air flow is obstructed, or for some patients who have had or have chronic lung diseases, exhalation is not entirely a relaxing process, but requires the participation of the expiratory muscles.

[0003] When you exhale forcefully, the internal intercostal muscles and abdominal muscles responsible for exhalation begin to contract; the contraction of the internal intercostal muscles causes the ribs to move downward, while the contraction of the abdominal muscles also causes the ribs to move downward, compressing the abdominal viscera and forcing the diaphragm to bulge upward, thereby reducing the volume of the chest cavity to a minimum and increasing the pressure within the lungs to a maximum, so that a large amount of carbon dioxide in the body can be exhaled.

[0004] Because some patients with chronic obstructive pulmonary disease or lung surgery have weak inspiratory and expiratory muscles due to physical abnormalities of the chest wall, relying on some breathing trainers to provide appropriate impedance for inhalation and exhalation training is beneficial to the recovery of these specific patients.

[0005] Because young children are not fully developed, the impedance required for their breathing training is much smaller than that of adult patients. The expiratory and inspiratory muscles of young children with lung diseases are weaker. Current breathing trainers are generally not suitable for young children, and the impedance required for different ages and developmental conditions also varies greatly. Summary of the Invention

[0006] The purpose of the present invention is to provide a breathing trainer suitable for use by younger children. Children of different age groups and developmental states have greatly different lung capacities. Therefore, in order to meet the needs of different children, the present invention provides a breathing trainer that can be suitable for different children.

[0007] The present invention provides a breathing trainer for infants, comprising a pipe, one end of which is connected to an air inlet and the other end of which is provided with an air hole. A sphere is provided inside the pipe, and the outer diameter of the sphere is equivalent to the inner diameter of the pipe. The sphere can roll in the pipe after being subjected to a certain gas pressure, and the gas pressure required to cause the sphere to roll is adjustable.

[0008] When a child exhales or inhales into the breathing trainer, the air pressure at the exhalation or inhalation end changes. This pressure difference multiplied by the area of ​​the tube determines the pressure applied to the ball. When the pressure applied to the ball exceeds the rolling friction between the ball and the tube, the ball overcomes the resistance and rolls along the tube. The present invention achieves its adaptability to different children by varying the force required to cause the ball to roll. This primarily involves changing the weight of the ball or the slope of the tube, thereby varying the force required to cause the ball to roll.

[0009] The first solution of the above-mentioned children's breathing trainer is to include a group of balls of different weights, and different balls are replaced according to different children. The implementation methods of balls of different weights include balls of different materials and densities, or hollow balls of different degrees, or other existing technologies, all of which can change the weight of the balls.

[0010] Furthermore, the sphere is a hollow sphere, which can be opened and closed, and a substance with a certain weight can be added therein, thereby changing the mass of the sphere.

[0011] Furthermore, the hollow sphere is composed of at least two layers with the same center. The hollow sphere is composed of two hemispherical hollow spheres. The outer diameters of the small spheres in two adjacent layers of the hollow sphere are equivalent to the inner diameter of the large sphere.

[0012] The second solution of the above-mentioned infant breathing trainer is that it includes a cylinder, the cylinder includes a pipe, the length direction of the cross-section of the cylinder is greater than the diameter of the pipe, the center of one end of the pipe deviates from the center of one end of the cylinder, and the center of the other end of the pipe coincides with the center of the cylinder or deviates in the opposite direction.

[0013] The third solution of the above-mentioned infant breathing trainer is that the cylinder is a hollow cylinder, the center of one end of the pipe with a cover coincides with the center of one end of the cylinder and is movably connected, the outer wall of the other end of the pipe is provided with a tooth pattern, and the inside of the cylinder is provided with a rack that matches the tooth pattern, the pipe air inlet pipe is exposed, and the air inlet pipe is sleeved with a wing, the cylinder has a baffle that cooperates with the wing, and the wing can move along the length direction of the air inlet pipe, and the wing has a first state supported by the baffle and a second state not in contact with the baffle.

[0014] The structure of the wing and baffle of the above-mentioned infant breathing trainer can be replaced by a card slot and a slide groove. The above-mentioned cylinder has a slide groove that matches the air inlet pipe. The slide groove is connected to several card slots. The slide groove is arranged along the height direction of the cylinder. The air inlet pipe can slide in the slide groove and can be stuck in any of the card slots.

[0015] The technical effects of the present invention are:

[0016] The present invention is different from adult respiratory trainers. Generally, respiratory trainers use a longitudinal pipe setting and achieve the training purpose by setting a larger impedance. However, the expiratory and inspiratory muscles of young children are not as developed as those of adults. When using vertical pipes, some young children cannot push the ball up by inhaling or exhaling. Therefore, in order to solve the problem of excessive impedance, the present invention uses a horizontal pipe setting and achieves the purpose of adapting to different children by adjusting the impedance. The present invention also measures the length of the ball pushed by the child by setting a scale. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Reference Figure 1As shown, a child breathing trainer of embodiment 1 includes a main pipe 1, a first end of the main pipe 1 is connected to the air inlet 2, and a second end is detachably connected to a cover 3 with an air hole, which can be connected by a threaded connection or by a snap fastener or other existing technology. The air inlet 2 can be connected to the breathing mouthpiece, and a sphere 4 is provided inside the main pipe 1. The outer diameter of the sphere 4 is equivalent to the inner diameter of the main pipe 1. The sphere 4 can roll in the main pipe 1 after being subjected to a certain pressure of gas. The gas pressure value required to cause the sphere 4 to roll is adjustable. In this embodiment, a child breathing trainer can be equipped with an array of spheres 4 of different weights. Spheres of different weights can be selected according to different age groups or developmental conditions. The structure of the cover 3 can refer to Figure 2 As shown, the air holes of the cover can make the air pressure at the second end of the main pipe the same as the atmospheric pressure. The cover and the main pipe are detachably connected, which makes it convenient to place the ball into the main pipe. The above-mentioned cover can also be replaced by the end face of the main pipe with air holes. The end face can also be without air holes, but the air holes can be set on the side wall of the main pipe away from the air inlet. The main pipe can also be provided with a scale to measure the length of the ball rolling. The end of the cover 3 connected to the main pipe 1 can also be provided with a spring or an elastomer. When the ball hits the spring or elastomer, it can be reset under the action of the elastic force.

[0028] In the above embodiment, the sphere 4 in the main pipe 1 is hollow. The sphere 4 can be composed of two hollow hemispheres, or it can have a window that can be opened and closed. A substance with a certain weight can be added to the sphere 4 through the window or hemisphere to change the weight of the sphere 4, thereby changing the friction between the sphere 4 and the main pipe 1, changing the impedance of the trainer, and thus changing the air pressure value required to push the sphere 4, thereby achieving the purpose of adjusting to adapt to different children's breathing training.

[0029] In the above embodiment, referring to Figure 3 As shown, the preferred solution is that at least two layers of concentric hollow balls with a certain weight are provided inside the main pipe 1. The hollow balls are composed of two hollow hemispheres. The outer diameters of the two adjacent layers of small balls are equivalent to the inner diameter of the large ball. This embodiment can keep the center of gravity of the ball 4 at the center of the ball 4, thereby improving stability.

[0030] Unlike the first embodiment, which changes the impedance of the breathing trainer by increasing or decreasing the mass of the sphere 4, the second embodiment changes the impedance of the trainer by adjusting the slope of the main pipe 1, thereby achieving the purpose of adjusting the breathing training for different children. Figure 4As shown, the barrel 5 includes a main pipe 1. The cross-sectional length of the barrel 5 is greater than the diameter of the main pipe 1. The center of one end of the main pipe 1 deviates from the center of the barrel 5, and the center of the other end of the main pipe 1 coincides with or deviates in the opposite direction from the center of the barrel 5. In this embodiment, the method for adjusting the impedance of the respiratory trainer is to rotate the barrel 5. When the barrel is rotated until the centers of the two ends of the main pipe are in a horizontal position, the respiratory trainer does not increase or decrease the impedance. When the barrel is rotated until the center of one end of the main pipe's air inlet is lower than the center of the other end of the main pipe, the main pipe is tilted upward, and the child needs to provide additional air pressure to resist the impedance caused by the change in the slope of the main pipe. When the barrel is rotated until the center of one end of the main pipe's air inlet is higher than the center of the other end of the main pipe, the impedance is reduced, which is suitable for use by younger children.

[0031] In the above embodiments, the cylinder is generally circular. After rotating the cylinder, the slope of the main pipeline can only be visually observed, and a certain slope or impedance cannot be fixed each time it is used. Therefore, the present invention provides a cylinder with a flat side, referring to Figure 5 As shown, in this embodiment, the cross-section of the cylinder is rectangular or polygonal. Its function is that when the cylinder is rotated, when the side of the cylinder with the flat surface faces downward, the flat surface contacts the table surface. At this time, the slope of the main pipe can be determined and reproduced. When manufacturing the cylinder and the main pipe, the cylinder can have multiple flat surfaces corresponding to different slopes of the main pipe, so that the cylinder plane can determine different slopes of the main pipe during use and is suitable for different children.

[0032] In the above embodiment, referring to Figure 6 、 Figure 7 As shown, the cylinder 5 is a hollow cylinder, the center of one end of the main pipe 1 with a cover 3 coincides with the center of one end of the cylinder 5 and is movably connected, a tooth pattern 6 is provided on the outer wall of the other end of the main pipe 1, and a rack 7 matching the tooth pattern 6 is provided inside the cylinder 5, the main pipe air inlet 2 pipe is exposed, and the air inlet 2 pipe is sleeved with a wing 8, and a baffle 9 is provided on the end face of the cylinder 5 to cooperate with the wing 8, and the wing 8 can be movable along the length direction of the intake pipe, and the wing 8 has a first state supported by the baffle 9 and a second state not in contact with the baffle.

[0033] Example 3 of the present invention is basically the same as Example 2, with the only difference being the different way in which the air inlet pipe 2 and the cylinder 5 cooperate. In Example 3, the cylinder 5 is a hollow cylinder, and the center of one end of the main pipe 1 with a cover 3 coincides with the center of one end of the cylinder 5 and is movably connected. The air inlet 2 pipes of the main pipe 1 are exposed, and the cylinder 5 has a slide groove 10 that cooperates with the air inlet pipe. The slide groove 10 is connected to several card slots 11. The slide groove 10 is arranged along the height direction of the cylinder 5, and the air inlet pipe can slide in the slide groove 10 and can be snapped into any of the card slots 11.

[0034] The above is only a preferred embodiment of the present invention. The scope of protection of the present invention is not limited to the above embodiments. For ordinary technicians in this technical field, several improvements and modifications without departing from the principles of the present invention should also be regarded as the scope of protection of the present invention.
