Description

Technical Field

[0001] The utility model relates to the technical field of medical treatment, and in particular to a lung function training device. Background Art

[0002] In modern traditional medicine, lung function-related exercise devices are used for the treatment and strengthening of the lungs. They are devices that help enhance and improve lung function. They are often used to treat and manage respiratory diseases such as asthma, chronic obstructive pulmonary disease, and in the rehabilitation process. A lung function exercise device is now designed.

[0003] According to Chinese patent: CN218106680U, a lung function exercise device includes: a cylinder, a handle is fixedly provided on the outer wall of one side of the cylinder, a suspension ball is provided in the cylinder, a fixed seat is provided at the bottom of the cylinder, an air intake pipe is connected in the middle of the bottom of the cylinder, the other end of the air intake pipe passes through the side wall of the fixed seat and is fixedly connected to a hose, a drying and purification box is fixedly connected to the top of the hose, a first drying layer, an adsorption layer and a second drying layer are arranged in sequence from top to bottom in the drying and purification box, and an air intake cover is detachably connected to the top of the drying and purification box. Based on the above-mentioned public patent and combined with the prior art, it is found that:

[0004] 1. At present, some lung function training devices have resistance adjustment function, which can adjust the resistance according to the current lung condition of the patient to achieve the effect of training and restoring lung function. However, some devices are relatively simple in adjusting the resistance and cannot intuitively reflect the specific value of the resistance, which makes it difficult to provide patients with quantitative training plans;

[0005] 2. The working principle of the device is that the patient blows air into the device with his mouth to increase the air pressure inside the device. During this period, the air pressure will form resistance to the lungs, which is helpful for lung treatment and exercise. When the patient blows air into the device, the pressure inside the device is greater than the external pressure, which will cause the internal gas to be pressurized to the outside. The air pressure formed may impact the patient's respiratory tract or lungs, causing a certain impact on the patient's lungs and causing lung tissue damage. Utility Model Content

The device can be set and operated by the control button 20 in combination with the display screen 2. An air intake pipe 4 is fixedly installed under the shell 1, and an air intake hood 3 is fixedly installed at the end of the shell 1. A person uses his mouth to blow into the air intake hood 3, and the gas is introduced into the device through the air intake pipe 4. A vacuum pump 5 is fixedly installed on the top of the shell 1, and a Hilintec D08 series micro vacuum pump is used. This type of pump has the characteristics of small size and low power consumption, and is particularly suitable for portable mobile devices.

[0046] like Figure 2 As shown, it includes: a micro respiratory flow meter 11, which is fixedly installed at the bottom of the inner side of the shell 1, and the air inlet pipe 4 is fixedly installed at its bottom. A sensor is installed in the micro respiratory flow meter 11. The gas entering the interior through the air inlet pipe 4 will pass through the micro respiratory flow meter 11, which is a device for measuring the respiratory airflow velocity. By blowing air into the pipeline of the flow meter, the sensor can measure the speed and flow of the airflow in real time, so as to evaluate the user's lung function and breathing status, and display the visual data on the display screen 2. A one-way valve 8 is fixedly installed above the micro respiratory flowmeter 11, and a movable plate 9 is movably arranged above the one-way valve 8. The gas pressurizes the space between the movable plate 9 and the micro respiratory flowmeter 11 through the one-way valve, so that the movable plate 9 moves upward. Just above the movable plate 9, a one-way valve 8 is also fixedly installed on the top of the inner side of the shell 1, and it is also fixedly installed below the vacuum pump 5. The vacuum pump 5 can pressurize the space above the movable plate 9. An air pressure sensor 10 is fixedly installed on the inner wall of the space above the movable plate 9, which can sense the pressure of the space above the movable plate 9 in real time and display it on the display screen 2. A No. 1 exhaust valve 6 is fixedly installed on the side of the shell 1, which can connect to the space above the movable plate 9 and discharge the gas inside it. The No. 2 exhaust valve 7 below the No. 1 exhaust valve 6 can connect to the space between the movable plate 9 and the micro respiratory flowmeter 11 and discharge the gas inside it.

[0047] like Figure 3-4 As shown, it includes: a vent pipe 12, which is the outermost metal structure of the one-way valve 8, an air outlet 13 and an air inlet 14 are respectively opened at both ends of the vent pipe 12, and a valve core 15 is arranged in the vent pipe 12, the valve core 15 is fixedly connected to the vent pipe 12 through a fixing ring 16, and a fixed pipe 17 is fixedly connected to one end of the fixing ring 16 through a connecting piece, the front half of the connecting rod 18 is slidably installed in the fixed pipe 17 and a return spring is arranged therein, and the end of the connecting rod 18 is fixedly connected to the valve 19, the two fixed pipes 17 are located on one side of the air inlet 14, so that the air can only flow from the air inlet 14 to the air outlet 13, the installation direction of the one-way valve below the movable plate 9: the air outlet 13 faces upward, and the installation direction of the one-way valve 8 above the movable plate 9: the air outlet 13 faces downward.

[0048] Working principle: The patient blows air into the air intake hood 3 through the mouth, and the gas enters the micro respiratory flowmeter 11 in the shell 1 through the air intake pipe 4. The gas enters the pipeline of the flowmeter, and the sensor can measure the speed and flow of the airflow in real time, so as to evaluate the user's lung function and breathing status, and display the visual data on the display screen 2. A one-way valve 8 is fixedly installed above the micro respiratory flowmeter 11. When the patient blows air into the device through the air intake hood 3 and the air intake pipe 4, the gas can only go out from the outlet 13. When the air pressure between the movable plate 9 and the micro respiratory flowmeter 11 increases and prevents subsequent gas from entering, the valve 19 will close to prevent gas backwashing and reduce the damage of gas backwashing to the patient's lungs. Probability, then open the No. 2 exhaust valve 7 to exhaust the gas, completing an exercise. When it is necessary to increase the exercise resistance, start the vacuum pump 5 to pressurize the space above the movable plate 9. At the same time, the air pressure sensor 10 can sense the pressure of the space above the movable plate 9 in real time and display it on the display screen 2, which more intuitively reflects the value of the resistance, and thus better provides patients with a quantitative exercise plan. A small speaker is installed on the side of the device, which can provide sound guidance in conjunction with the intelligent program to guide users to the correct breathing method and rhythm to achieve the best training effect. The device can also record, store and track the patient's training data, and can perform data analysis and personal progress reports through mobile phone applications or cloud platforms.
