Description

Technical Field

[0001] The invention relates to the technical field of lung capacity training for children in respiratory medicine, and in particular to a lung capacity training device for children in respiratory medicine. Background Art

[0002] Vital capacity refers to the total amount of gas exhaled after a full inhalation. Vital capacity = tidal volume + inspiratory reserve volume + expiratory reserve volume. Tidal volume refers to the amount of gas inhaled or exhaled during each breath. Inspiratory reserve volume is also called inspiratory reserve volume, which refers to the amount of gas that can be inhaled after a normal inhalation and a full inhalation. Expiratory reserve volume is also called expiratory reserve volume, which refers to the amount of gas that can be exhaled after a normal exhalation and a full exhalation.

[0003] Vital capacity is the maximum ventilation volume in one breath, which can reflect the potential capacity of respiratory function in a certain sense. After the introduction of the national student physical fitness standard, it has become a new worry for many parents. Some children are born with small vital capacity and barely reach or even fail to reach the passing standard of vital capacity. Some children cannot control their breathing and suffer from hypoxia and dizziness. Improving children's vital capacity is very important and necessary. Putting aside physical tests, it can enhance children's cardiopulmonary function and effectively avoid the incidence of bronchitis, asthma and pneumonia. Increasing vital capacity can also promote blood circulation and make children energetic.

[0054] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] Embodiment 1:

[0056] like Figures 1 to 11 As shown, this embodiment proposes a child respiratory medicine vital capacity training device, including an installation support plate 1, a liquid collecting mechanism 2, a pressure display cylinder 3, a magnetically controlled resistance adjustment component 4, a digital display component 5, a one-way valve mechanism 6, a connecting bottom plate 7, an air-blowing sealed shell 8 and a pneumatic fan 14 arranged inside the air-blowing sealed shell 8.

[0057] Among them, a blast enclosure 8 is installed at the middle position of the upper end of the mounting plate 1, and an air-driven fan 14 is arranged inside the blast enclosure 8. The inner side cross-section of the blast enclosure 8 is a circle, which can just accommodate the air-driven fan 14. The rotating shafts on both sides of the air-driven fan 14 are respectively connected to the two sides of the blast enclosure 8, and the connection of the rotating shafts is sealed. An air inlet pipe 12 and an air outlet pipe 13 are fixedly connected to the front and rear of the outside of the blast enclosure 8, and the air inlet pipe 12 and the air outlet pipe 13 are fixedly connected to the front and rear of the outside of the blast enclosure 8. 2 and the interior of the air outlet pipe 13 are connected to the interior of the air blast enclosure 8, the air inlet pipe 12 delivers gas to the interior of the air blast enclosure 8, the gas flows from front to back, and the interior of the air blast enclosure 8 is sealed, the pneumatic fan 14 is rotated to the lowest blade and the pneumatic fan 14 starts to rotate, a circular rotating iron block 401 is fixedly connected to one side of the connecting shaft of the pneumatic fan 14, and an auxiliary resistance magnet 402 is fixedly connected to both sides of the outer side of the rotating iron block 401, and the auxiliary resistance The magnet 402 is made of neodymium iron boron material. A fixed ring 403 is fixedly connected to one side of the inside of the air-blowing closed shell 8 near the rotating iron block 401. The fixed ring 403 covers the rotating iron block 401 on the outside, and an electromagnet 404 is fixedly connected to the upper and lower parts of the fixed ring 403. The electromagnet 404 can adjust the intensity of the magnetic field by adjusting the magnitude of the current, so as to adjust the rotation resistance of the pneumatic fan 14. A current control knob 405 is fixedly connected to one side of the upper front side of the mounting support plate 1 near the rotating iron block 401. The resistance of the pneumatic fan 14 is adjusted by rotating the current control knob 405. In order to visualize the speed of rotation of the pneumatic fan 14, a speed indicator light 21 is fixedly connected to one side of the upper end of the mounting support plate 1 away from the current control knob 405. The faster the pneumatic fan 14 rotates, the more speed indicator lights 21 light up from bottom to top. This adjustment of different gears can be used to stimulate the child's competitive spirit, so as to achieve the purpose of exercising lung capacity.

[0058] where F∝B 2 .v

[0059] F is the resistance, B is the magnetic field strength, and v is the rotation speed of the rotating iron block 401, which is equivalent to the rotation speed of the flywheel.

[0060] In order to allow the child to blow air into the interior of the air-sealed shell 8, a support column 9 is fixedly connected to the middle part of the upper front end of the mounting support plate 1, and a connecting elbow 11 is fixedly connected to the upper end of the support column 9. The upper end of the connecting elbow 11 is bent forward, and the other end of the air intake pipe 12 connected to the air-sealed shell 8 passes forward from the bent rear end of the connecting elbow 11 to the front end of the connecting elbow 11, and a replaceable and disassembled blowing nozzle for children to blow is plugged into the front end. The blowing nozzle is used to blow air into the interior of the air intake pipe 12, and the pneumatic fan 14 is allowed to rotate inside the air-sealed shell 8. An air pressure monitoring sensor 501 is connected to the air intake pipe 12, and the air pressure monitoring sensor 501 is used to digitally display the gas blown out from the inside of the air intake pipe 12. A digital display screen 502 is fixedly connected to the side of the upper end of the mounting support plate 1 away from the speed indicator light 21, and the digital display screen is used to display the air pressure of the air intake pipe 12. 502 is the reading displayed by the air pressure monitoring sensor 501 for recording the vital capacity value. In order to facilitate the installation of the supporting plate 1 for lifting and lowering adjustment for children of different heights, a connecting base plate 7 is arranged below the supporting plate 1. A synchronous lifting cylinder 17 is fixedly connected to the front and rear ends of the upper ends of the connecting base plate 7. The upper telescopic parts of the two synchronous lifting cylinders 17 are respectively fixedly connected to the front and rear ends of the lower ends of the supporting plate 1. A control switch 18 for controlling the extension and retraction of the synchronous lifting cylinder 17 is arranged on one side of the current control knob 405 fixedly connected to the upper end of the supporting plate 1 to control the lifting and lowering of the supporting plate 1. At the same time, an L-shaped handle 10 is fixedly connected on both sides of the support column 9 to facilitate children to hold the handle 10 when performing vital capacity training, to facilitate force and maintain stability, and the L-shaped handle 10 can be used for both vertical and horizontal parts.

[0061] In order to prevent saliva from being blown into the interior of the air-sealed shell 8 when the child blows, a liquid separation chamber 201 is opened along the inside of the support column 9 and the connecting elbow 11. When the child blows air into the air inlet pipe 12 inserted into the connecting pipe 11, it flows downward to a certain distance and then flows downward at the position where the liquid separation chamber 201 connects to the air inlet pipe 12. A detachable liquid collecting bottle 202 is threadedly connected to the front end of the lower side of the mounting plate 1. The liquid collecting bottle 202 is connected through the interior of the liquid separation chamber 201 and the interior of the air inlet pipe 12, and the connection between the liquid collecting bottle 202, the liquid separation chamber 201 and the air inlet pipe 12 is sealed, so that saliva flows downward by gravity after reaching the position of the liquid separation chamber 201 and is collected by the liquid collecting bottle 202 for easy handling and cleaning.

[0062] In order to avoid some children who are too young or do not have the ability to distinguish the size of numbers, so that they can easily understand the size of their lung capacity, a cylindrical pressure-indicating cylinder 3 is fixedly connected to the rear end of the upper side of the mounting plate 1. The pressure-indicating cylinder 3 is made of transparent plastic material. A circular air pressure buoy 15 is arranged inside the pressure-indicating cylinder 3. The outer edge of the air pressure buoy 15 is fitted with the inner wall of the pressure-indicating cylinder 3. The air pressure buoy 15 divides the pressure-indicating cylinder 3 into two separate and unconnected spaces. Since the largest plane distance inside the pressure-indicating cylinder 3 is the inner diameter, the outer diameter of the air pressure buoy 15 and the inner wall of the pressure-indicating cylinder 3 are the same. The inner diameters of the pressure-indicating cylinder 3 are the same. If the air buoy 15 is to be tilted, the longest horizontal distance of the air buoy 15 will be longer than the inner diameter of the pressure-indicating cylinder 3. Therefore, the air buoy 15 can only move up and down in a straight line and cannot be tilted. In order to balance the pressure changes in the upper half of the space inside the pressure-indicating cylinder 3 separated by the air buoy 15 due to the up and down movement of the air buoy 15, which affects the up and down movement of the air buoy 15, an air pressure balance connecting pipe 19 is fixedly connected to the rear side of the upper end of the outer side of the pressure-indicating cylinder 3, so that the upper half of the space of the air buoy 15 is at a standard atmospheric pressure. When a child passes through the air intake When air is blown through the tube 12, the air flow enters from the inside of the air inlet pipe 12. Since the inside of the liquid separation chamber 201 is blocked by the liquid collecting bottle 202 at the lower end, the blown gas cannot enter and move downward from the liquid separation chamber 201, and can only pass through the inside of the air pressure sensing monitoring sensor 501 from the air inlet pipe 12. After being sensed by the air pressure sensing monitoring sensor 501, the value is fed back to the digital display screen 502. Next, the air flow passing through the air pressure sensing monitoring sensor 501 enters from the inside of the air-blowing closed shell 8 to drive the pneumatic fan 14, thereby driving the pneumatic fan 14 to rotate. The rotation of the pneumatic fan 14 utilizes electromagnetic induction to enter The magnetic lines of force are cut to generate electricity, and the generated current flows to the speed indicator light 21, making the speed indicator light 21 light up. Then the gas flows backward and blows into the interior of the pressure indicating cylinder 3, so that the air pressure buoy 15 moves up, and finally stops to compare the scale of the pressure indicating cylinder 3 to compare the high and low. In order to allow the air flow to enter the interior of the pressure indicating cylinder 3, the air pressure buoy 15 must be blown upward. A positioning ring 20 is provided inside the pressure indicating cylinder 3. The positioning ring 20 is hollow in the middle, and the bottom plane of the positioning ring 20 is above the connection between the air outlet pipe 13 and the pressure indicating cylinder 3, to ensure that the gas enters from below to lift the air pressure buoy 15.

[0063] In order to allow the air pressure buoy 15 to remain at its original height after being lifted up and the blowing stops, a one-way valve mechanism 6 is provided on the air outlet pipe 13, which is connected to the air outlet pipe 13 by a connecting sleeve 601. The interior of the connecting sleeve 601 is sealed and connected to the interior of the air outlet pipe 13. An embedded sealing tube 602 is provided inside the connecting sleeve 601. The outer wall of the embedded sealing tube 602 is tightly connected to the inner wall of the connecting sleeve 601. A hollow movable ball 603 is provided inside the embedded sealing tube 602. The outer wall of the embedded sealing tube 602 is tightly connected to the inner wall of the connecting sleeve 601. A small blocking hole 604 is opened at the front and back of the part, and the hollow movable ball 603 can just block the blocking hole 604 when it moves back and forth. In order to allow the airflow to flow only from front to back and prevent the airflow from moving from back to front, a circle of evenly distributed connecting holes 605 is opened on the outer rear side of the embedded sealing tube 602. When the child stops blowing, the air pressure buoy 15 will tend to fall under the influence of gravity, and the internal gas will tend to be compressed to squeeze the hollow movable ball 603 forward, blocking the blocking hole 604 on the front side, and sealing the inside of the air outlet pipe 13.

[0064] In order to facilitate the restoration of the air pressure buoy 15 that has been blown up downward after the air is blown, a sleeve shell 1601 that is connected to the inside of the pressure indicating cylinder 3 is fixedly connected to the upper side of the positioning ring 20 at the rear end of the lower side of the mounting plate 1 and aligned with the position of the pressure indicating cylinder 3. A control rod 1602 with a smaller inner diameter is inserted into the opening at the lower end of the sleeve shell 1601, and a limiting air-permeable sleeve ring 1604 is arranged inside the sleeve shell 1601. The limiting air-permeable sleeve ring 1604 has a circular ring in the middle and is connected to the inner wall of the sleeve shell 1601 through a plurality of support rods on the outside to limit the control rod 1602 and ensure that the control rod 1602 goes straight up and down. A sealing baffle 1602, when the sealing baffle 1602 moves to the lower end, it blocks the air outlet at the lower end of the sleeve shell 1601 to perform sealing. When the sealing baffle 1602 is pushed upward to the inside of the sleeve shell 1601 by the lower end of the control rod 1602, the air outlet position at the lower end of the outer side of the sleeve shell 1601 is not blocked and exhaust can be performed. In order to ensure that the sealing baffle 1602 seals the sleeve shell 1601, an extrusion spring 1605 is mounted on the control rod 1602. The extrusion spring 1605 is between the sealing baffle 1602 and the limiting breathable ring 1604 to squeeze the sealing baffle 1602 downward to block the air outlet at the lower end of the sleeve shell 1601.
