Description

Technical Field

[0001] The utility model relates to the technical field of breathing trainers, in particular to a sputum removal breathing trainer. Background Art

[0002] At present, there are more and more patients with respiratory diseases, including chronic obstructive pulmonary disease, asthma, chronic bronchitis, emphysema, pneumonia, etc., which are very common diseases and seriously endanger human health. One of the reasons why patients' conditions often relapse is that they have combined respiratory muscle dysfunction and expectoration disorder. Effective breathing training can improve these patients' symptoms, quality of life, lung function and medical resource utilization, and may also prolong their survival. Existing breathing training devices either have relatively simple functions and only perform simple inspiratory muscle exercises on patients. The intensity of inspiratory muscle exercise is single and mismatched, and different breathing training devices are required to complete inspiratory muscle training and assist expectoration, or the price of breathing training devices is too expensive. Utility Model Content

[0003] The utility model aims to provide a sputum removal breathing trainer to solve the problem that patients with respiratory diseases cannot help to remove sputum while performing breathing training.

[0004] The above technical purpose of the utility model is achieved through the following technical scheme, including a gas cylinder, a piston, and a vibrating expectorant, the gas cylinder having an air hole at the upper end, the gas cylinder having a piston slidably connected inside the gas cylinder, the air hole at the upper end of the gas cylinder having a T-shaped airway fixedly connected thereto, the upper and lower ends of the T-shaped airway being provided with a one-way air permeable component, the upper end of the T-shaped airway being fixedly connected thereto, the right end of the T-shaped airway being threadedly connected to a hose, the hose being communicated with the T-shaped airway, one end of the hose being fixedly connected to an air nozzle, the bottom of the gas cylinder being hollow, and a base being provided at the bottom of the gas cylinder.

[0005] The principle and effect of the above technical solution: when the patient exhales, the gas passes through the air nozzle, hose, T-shaped airway, one-way air permeable component at the upper end of the T-shaped airway, and vibrating expectorant in turn, and the gas oscillates inside the vibrating expectorant, thereby driving the gas oscillation in the patient's airway. The gas oscillation impact in the airway reduces the viscosity of the sputum in the patient's airway, thereby loosening the sputum and making it easy to fall off. When the patient inhales, the air pressure in the enclosed space formed by the air nozzle, hose, T-shaped airway, one-way air permeable component at the lower end of the T-shaped airway, gas cylinder, and piston is reduced. The bottom of the gas cylinder is provided with an air hole connected to the atmosphere, and the bottom of the piston is affected by the atmospheric pressure. At this time, the atmospheric pressure at the bottom of the piston will push the piston upward. At this time, the pressure difference between the upper and lower parts of the piston gradually decreases. If the patient wants to continue to suck the piston upward, it is necessary to provide a greater suction force, so that the patient's respiratory muscle strength is exercised.

[0006] The utility model is further configured as follows: the gas cylinder is made of a transparent material, the upper and lower ends of the outer wall of the gas cylinder are commonly fixedly connected to a limiting column, a gap is provided between the limiting column and the gas cylinder, the limiting column is slidably connected to two clips, both of the two clips are fixedly connected to an indicator needle, and the outer wall of the gas cylinder is provided with scale lines.

[0007] By adopting the above technical solution, the gas cylinder is made of transparent material, and the surface of the gas cylinder is provided with scale lines, so that the height of the piston rise can be accurately observed. The indicator needle is fixed to different heights of the limit column by a clip, the lower indicator needle is clamped at the height position of the piston when the patient inhales normally, and the upper indicator needle is clamped at the exercise target height set by the doctor for the patient, so as to achieve the effect of identifying the patient's current lung condition and then setting a suitable training goal for him.

[0008] The utility model is further configured that the base is provided with an air inlet channel, the air inlet channel runs through two sides of the base and communicates with the bottom of the gas cylinder, and the base is threadedly connected to the gas cylinder.

[0009] By adopting the above technical solution, different pistons can be replaced through the threaded connection between the gas cylinder and the base, allowing patients to gradually adapt to different stages of training. In addition, the expectoration breathing trainer is placed stably on the desktop, solving the problem that the patient needs to hold the trainer all the time during training.

[0010] The utility model is further configured that a filter is fixedly connected to the upper end of the air intake passage.

[0011] By adopting the above technical solution, when the patient inhales, the filter screen provided at the end of the circular tube can filter out dust and other particulates in the air to prevent the dust and other particulates from being inhaled into the body by the patient.

[0012] The utility model is further configured as follows: the one-way air permeable component is composed of an annular flange, a rotating shaft, a baffle, and a compression spring; the annular flange and the T-shaped air duct are integrally formed on the inner wall of the T-shaped air duct; the baffle is rotatably connected to the upper side of the annular flange via the rotating shaft; the baffle covers the channel in the middle of the annular flange; a compression spring is fixedly connected to the upper side of the baffle away from one end of the rotating shaft; and the free end side of the compression spring is fixedly connected to the T-shaped air duct.

[0013] By adopting the above technical solution, when the patient exhales, the compression spring at the lower end of the T-shaped airway tube pushes the baffle plate downward to move around the rotating axis, the annular flange blocks the baffle plate from moving downward, and the annular flange cooperates with the baffle plate to close the lower end channel of the T-shaped airway tube. The baffle plate at the upper end of the T-shaped airway tube moves upward around the rotating axis under the pressure of the patient's exhaled gas, thereby opening the upper end channel of the T-shaped airway tube. When the patient inhales, the compression spring at the upper end of the T-shaped airway tube pushes the baffle plate to move downward around the rotating axis, the annular flange blocks the baffle plate from moving downward and cooperates with the baffle plate to close the upper channel of the T-shaped airway tube. The air pressure in the T-shaped airway tube gradually decreases, and the gas pressure sealed by the annular flange at the lower end of the T-shaped airway tube, the baffle plate, the piston, and the gas cylinder is greater than the air pressure in the T-shaped airway tube, thereby pushing the baffle plate at the lower end of the T-shaped airway tube upward around the rotating axis.

[0014] The utility model is further configured as follows: the vibrating expectorant includes a V-shaped groove, a vibrating ball, a cover and an air flow channel, the bottom of the V-shaped groove is provided with a plurality of through holes, the through holes are smaller than the diameter of the vibrating ball, the vibrating ball is in the V-shaped groove, the V-shaped groove and the air flow channel are integrally formed, the V-shaped groove is threadedly connected to the cover, the cover is provided with a plurality of breathable through holes, and the air flow channel is connected to the T-shaped airway.

[0015] By adopting the above technical solution, when the patient exhales, the gas from the T-tube enters the airflow channel, and the vibrating ball rolls up and down in the V-shaped cone, rising and falling very quickly, causing airflow vibration, and the air in the respiratory airway will also oscillate, thereby shearing secretions in the respiratory airway, reducing the viscoelasticity of the device, and helping to expectorate. The lid is opened to add vibrating balls of other sizes inside to increase resistance. The required exhaled volume needs to be increased to achieve the vibration effect, thereby continuously strengthening the training effect.

[0016] The utility model is further configured that a rotor flowmeter is arranged on the right side of the T-shaped air guide pipe.

[0017] By adopting the above technical solution, when the patient breathes and the gas passes through the T-tube, the rotor flowmeter can display the breathing flow rate, which is convenient for the doctor to observe the patient's training status.

[0018] In summary, the utility model has the following beneficial effects: the patient repeatedly performs exhalation and inhalation cycle training, which can help expectoration when exhaling, and can exercise the strength of the lungs when inhaling, thereby improving the patient's chest contraction and expansion capabilities.

[0025] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0026] A sputum removal breathing training device, such as Figure 1-3As shown, it includes a gas cylinder 1, a piston 3, and a vibrating expectorant 5. The gas cylinder 1 is made of transparent materials such as PC and PP. The upper and lower ends of the outer wall of the gas cylinder 1 are fixedly connected to a limiting column 8. The upper and lower ends of the limiting column 8 are fixedly connected to the outer wall of the gas cylinder 1, and a gap is left between the limiting column 8 and the gas cylinder 1. Two clips 9 are slidably connected to the limiting column 8. The two clips 9 are fixedly connected to the side away from the gas cylinder 1. The two indicating needles 10 are arranged horizontally and parallel to each other. The outer wall of the gas cylinder 1 is provided with scale lines 11, which are arranged vertically and are located on the movement path of the indicating needle 10. The piston 3 is slidably connected to the inside of the gas cylinder 1. The diameter of the piston 3 is slightly smaller than the diameter of the gas cylinder. The upper end of the gas cylinder 1 is provided with an air hole 2. The lower end of the gas cylinder 1 is hollow, and the outer wall of the bottom of the gas cylinder 1 is provided with an external thread. The bottom of the gas cylinder 1 is connected to a base 13, and a groove is provided in the center of the base 13, and the groove is provided with an internal thread that matches the external thread of the outer wall of the bottom of the gas cylinder 1. The base 13 is provided with an air inlet passage 19, which passes through the base 13 and communicates with the lower end of the gas cylinder 1. The upper end of the gas cylinder 1 is fixedly connected with a T-shaped air guide tube 4 located at the air hole 2, and the lower end opening of the T-shaped air guide tube 4 is the same shape and size as the air hole 2 at the upper end of the gas cylinder 1. The upper and lower ends of the T-shaped airway 4 are provided with one-way air permeable components, a rotor flowmeter 12 is provided on the right side of the T-shaped guide tube, and the T-shaped airway 4 is fixedly connected with a vibrating expectorant 5 located on the upper side of the one-way air permeable component, and the vibrating expectorant 5 includes a V-shaped groove 21, a vibrating ball 20, a cover 22 and an air flow channel 23, the bottom of the V-shaped groove 21 is a through hole, the through hole is smaller than the diameter of the vibrating ball 20, the vibrating ball 20 is in the V-shaped groove 21, the V-shaped groove 21 and the air flow channel 23 are integrally formed, the V-shaped groove 21 is threadedly connected to the cover 22, the cover 21 has a number of air permeable through holes, and the air flow channel 23 is connected to the T-shaped airway 4. The right end of the T-shaped airway 4 is provided with an external thread, and the right end of the T-shaped airway 4 is threadedly connected with a hose 6, one end of the hose 6 is provided with an internal thread that matches the external thread on the right end of the T-shaped airway 4, and the other end of the hose 6 is fixedly connected with a gas nozzle 7.

[0027] like Figure 4 As shown, the one-way air permeable component is composed of an annular flange 15, a rotating shaft 16, a baffle 17, and a compression spring 18. The annular flange 15 is integrally formed with the T-shaped airway 4, and the annular flange 15 is located on the inner side of the T-shaped airway 4. The side wall of the T-shaped airway 4 is rotatably connected to the rotating shaft 16, and the rotating shaft 16 is located on the upper side of the annular flange 15. The rotating shaft 16 is fixedly connected to the baffle 17, and the baffle 17 is a circular sheet. The diameter of the baffle 17 is smaller than the inner diameter of the T-shaped airway 4, and the diameter of the baffle 17 is larger than the inner diameter of the annular flange 15. The end of the baffle 17 away from the rotating shaft 16 is fixedly connected to the compression spring 18. The other end of the compression spring 18 is fixedly connected to the T-shaped airway 4, and the end of the compression spring 18 fixedly connected to the T-shaped airway 4 is located on the upper side of the rotating shaft 16.

[0028] Working principle: When the patient exhales, the compression spring 18 at the lower end of the T-shaped airway tube 4 presses the baffle 17 downward to move downward around the rotating shaft 16, and the annular flange 15 prevents the baffle 17 from moving downward. The annular flange 15 cooperates with the baffle 17 to close the lower end channel of the T-shaped airway tube 4. The baffle 17 at the upper end of the T-shaped airway tube 4 moves upward around the rotating shaft 16 under the pressure of the patient's exhaled gas, thereby opening the channel at the upper end of the T-shaped airway tube 4. The exhaled gas passes through the air nozzle 7, the hose 6, the T-shaped airway tube 4, the one-way air permeable component at the upper end of the T-shaped airway tube 4, and the vibrating expectorant 5 in sequence. After the gas enters the vibrating expectorant 5, the gas inside the vibrating expectorant 5 oscillates, driving the gas oscillation on the entire channel, thereby driving the gas oscillation in the patient's airway. The gas oscillation in the airway impacts the sputum adhering to the airway, reducing the viscosity of the sputum in the patient's airway so that the sputum is loose and easy to fall off. When the patient wants to increase the exhaled volume, the cover 22 is opened to add an appropriate amount of vibration balls 20, or a heavier vibration ball 20 is replaced. The patient needs to exhale more force to make the vibration ball 20 vibrate, so that the patient's respiratory muscle strength is exercised. When the patient inhales, the compression spring 18 at the upper end of the T-shaped airway 4 pushes the baffle 17 to move downward around the rotating shaft 16, and the annular flange 15 prevents the baffle 17 from moving downward and cooperates with the baffle 17 to close the upper channel of the T-shaped airway 4. During the patient's inhalation, the air pressure in the T-shaped airway tube 4 gradually decreases, and the air pressure in the enclosed space surrounded by the baffle 17, piston 3, and gas cylinder 1 located at the lower side is greater than the air pressure in the T-shaped airway tube 4, thereby pushing the baffle 17 upward around the rotating shaft 16; at this time, the air pressure in the enclosed space surrounded by the air nozzle 7, hose 6, T-shaped airway tube 4, gas cylinder 1, and piston 3 decreases, causing the piston 3 to move upward under the action of atmospheric pressure. At this time, the pressure difference between the upper and lower parts of the piston 3 gradually decreases. If the patient wants to continue to suck the piston upward, a greater suction force needs to be provided. When the patient sucks the piston 3 to the maximum scale line 11 or cannot suck it up, the base 13 is removed from the gas cylinder and replaced with a piston 3 of suitable quality, thereby exercising the patient's respiratory muscle strength.

[0029] When the doctor needs to customize different training goals for different patients, the height to which the piston 3 rises can be accurately observed through the transparent gas cylinder 1 and the scale line 11. The indicator needle 10 is fixed to different heights of the limit column 8 by the clip 9. The lower indicator needle 10 is clamped at the height position of the piston 3 when the patient inhales normally, and the upper indicator needle 10 is clamped at the exercise target height set by the doctor for the patient. In addition, the rotor flowmeter 12 can be used to observe the breathing flow rate, so as to identify the patient's current lung condition and then set a suitable training goal for him. The filter 14 arranged at the upper end of the ventilation duct can filter dust and other particulate matter in the air to prevent inhalation into the patient's body. The base 13 is provided with an air inlet channel 19 so that the pressure of the space formed by the lower part of the piston 3 and the bottom of the gas cylinder 1 is equal to the atmospheric pressure.

After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
