Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of chronic obstructive pulmonary disease treatment, and particularly relates to a respiratory training and respiratory frequency feedback respirator for chronic obstructive pulmonary disease patients. BACKGROUND

[0002] Chronic obstructive pulmonary disease (COPD for short) is a common respiratory disease with the typical characteristic of persistent airflow limitation. It belongs to the category of preventable and treatable diseases, but the airflow limitation will develop in a progressive manner. The occurrence of this disease is closely related to the enhanced chronic inflammatory response of airways and lungs to toxic particles or gases.

[0003] In the treatment process of COPD, regular respiratory training is a very critical link. Through effective respiratory training, the lung capacity of a single breath of a patient can be enhanced, thereby reducing the frequency of COPD complications and improving the quality of life of the patient. In order to meet the needs of patients for daily respiratory training, professional respiratory training devices have emerged. With the rapid development of modern medical technology, the functions and structures of COPD patient respiratory training devices are constantly optimized and upgraded, aiming to provide patients with more efficient and more convenient use experience.

[0004] In view of the respiratory training needs of COPD patients, the patent with publication number CN120053942A proposes a nasal respiratory training device for COPD rehabilitation nursing. The working principle of the device is that when the patient breathes through the nasal cavity, the external airflow slowly enters the cavity inside through the opening of the respirator, driving the rotating ball to start rotating. In the rotating process of the rotating ball, the gap range between the arc-shaped notch and the corner of the triangular block will change constantly, showing the rule of changing from small to large and then from large to small. This change can provide variable weak resistance for the patient when breathing through the nasal cavity, ensuring that the amount of air inhaled by the patient is uniform and the breathing journey is persistent and slow in each breathing cycle, so as to achieve the effect of deep breathing, which is helpful for the rehabilitation training of the patient.

[0005] However, the above technical solution still has certain limitations when actually applied to the respiratory training of COPD patients. Although it can ensure the uniformity of the amount of air inhaled by the patient to a certain extent, the patient still needs to rely on his own strength to complete the inhalation and exhalation of air in order to maintain the uniformity of the amount of air. However, the severity of the disease of COPD patients varies, and some patients have more serious conditions. In the process of breathing, some patients may have difficulty breathing, or even cannot breathe autonomously in the middle. In this case, if there is no professional medical staff around the patient to assist him in inhaling oxygen in time, the patient may be suffocated due to lack of oxygen, which may cause irreparable serious consequences.

[0006] Furthermore, existing COPD ventilators have another deficiency in their functional design: the lack of a tangible feedback function for the effectiveness of breathing training. When using the ventilator for training, patients cannot intuitively understand their own recovery progress, making it difficult to judge whether the training is effective and to what extent. This may not only affect patients' motivation and adherence to training but also hinder doctors from adjusting the training plan in a timely manner based on the patient's actual situation.

[0007] In view of the problems existing in the prior art, this design proposes a respiratory training and respiratory rate feedback respirator for COPD patients, aiming to provide COPD patients with a safer and more effective respiratory training solution and help patients and doctors understand the effectiveness of respiratory training in a timely manner. Summary of the Invention

[0008] To address the aforementioned problems, this invention provides a respiratory training and respiratory rate feedback respirator for COPD patients, thereby resolving the issues raised in the background section.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a respiratory training and respiratory rate feedback ventilator for COPD patients, comprising a ventilator base and an air delivery canister, wherein an auxiliary air delivery mechanism, a disinfection component, and a respiratory feedback component are distributed on the inner and outer sides of the air delivery canister, respectively. The auxiliary gas delivery mechanism includes an air inlet hopper installed on one side of the top of the gas delivery tank. A first through slot is opened below the air inlet hopper on the top of the gas delivery tank. A first flow limiting plate is installed at one end of the inner wall of the gas delivery tank. A second flow limiting plate is installed on the inner wall of the first through slot. An air intake fan is installed on the inner wall of the air inlet hopper. A pressure sensor is installed at the other end of the inner wall of the gas delivery tank. A second through slot is opened on one side of the bottom of the gas delivery tank. Multiple connecting slots are equally spaced on one side of the first flow limiting plate and one side of the second flow limiting plate. A baffle plate is rotatably connected to one side of the inner wall of each connecting slot. A torsion spring is fixedly installed at both ends of each baffle plate, and one end of each torsion spring is fixedly connected to both sides of the inner wall of each connecting slot. Preferably, a dustproof plate is installed at the upper edge of the inner wall of the air intake hopper, a wire is inserted between one end of the air guide tank and one side of the air intake hopper, an air intake pipe is inserted between the other end of the air guide tank, and the air pressure sensor is electrically connected to the air intake fan through the wire.

[0010] Preferably, the disinfection component includes a liquid inlet tube installed on one side of the top of the air delivery tank, a sealing valve installed on one side of the liquid inlet tube, and a third through groove opened on the top of the air delivery tank below the liquid inlet tube.

[0011] Preferably, a first conduit is inserted into the inner wall of the second through groove, and an air intake base is installed at the edge of the top side of the respirator base, with one end of the first conduit inserted into the inner wall of the air intake base.

[0012] Preferably, the respiratory feedback component includes three transparent support tubes that are equidistantly installed on the other side of the top of the respirator base, and the tops of the three transparent support tubes are respectively fixedly connected to the bottom of the air delivery canister, and an air delivery groove is provided in the middle of the inner wall of the respirator base.

[0013] Preferably, the top of the respirator base is provided with air inlets below the three transparent support tubes, the inner wall of each air inlet is connected to the inner wall of the air guide groove, floats are inserted into the inner walls of the three transparent support tubes, and vacuum grooves are provided on the inner wall of each float.

[0014] Preferably, a second conduit is inserted through the inner wall of the air intake pipe, one end of the second conduit is fixedly connected to a face mask, and the inner wall of one end of the second conduit communicates with the inner wall of the face mask, and a rubber strap is fitted on the outer edge of the face mask.

[0015] Preferably, a control panel is installed on one side of the respirator base, and the air intake fan and air pressure sensor are electrically connected to an external power supply through the control panel.

[0016] The technical effects and advantages of this invention are as follows: 1. This invention, through the provision of an auxiliary gas delivery mechanism, allows the patient to inhale during breathing. The airflow in front of the first flow-limiting plate inside the gas delivery canister is drawn away, reducing the air pressure in front of the first flow-limiting plate. Under the pressure of the air pressure on the other side of the first flow-limiting plate inside the gas delivery canister, the upper baffle plate is squeezed and rotated, thereby opening the connecting groove on the first flow-limiting plate. This allows airflow to be continuously drawn out from the other end of the gas delivery canister. When the patient's breathing is obstructed, the pressure change suddenly drops. When this sudden drop in pressure reaches a certain range, the pressure sensor in the gas delivery canister will detect it. The change is triggered by a signal transmitted to the upper intake fan via a wire, which then starts the intake fan. Once started, the intake fan blows the baffle on the second flow limiter, causing it to rotate and open the connecting slot on the second flow limiter, thus opening the passage of the first channel. This allows external air to be introduced into the air delivery canister through the intake hopper and the first channel, and then flow into the patient's airway to assist breathing. This helps to avoid the risk of suffocation and shock caused by COPD complications during daily breathing training, thereby improving the safety of COPD patients during breathing training. 2. This invention, by setting up a disinfection component, allows for convenient use by the next patient after respiratory training. The sterilization bottle or connecting tube for disinfection can be inserted into the infusion tube, and the sealing valve is opened to introduce the disinfectant solution into the air delivery canister. Most ordinary disinfection devices spray the disinfectant solution in a mist, which flows within the air delivery canister and is eventually discharged or evaporated, disinfecting the inside of the air delivery canister and facilitating continued use by the next patient. This solves the problem of inconvenient disinfection inside ordinary ventilators, which can easily lead to cross-infection. 3. This invention incorporates a respiratory feedback component. The inner wall of the air intake base is connected to the air guide groove via the inner wall of the respirator base. The patient's exhaled air is then guided into the air guide groove through the first catheter and the air intake base. The exhaled air flows within the air guide groove, sequentially entering each air intake hole and then the upper transparent support tube. The greater the air intake, the stronger the air pressure at the bottom of the transparent support tube, causing the float within to float within the tube. Based on the intensity of the respiratory vital capacity, the air sequentially enters the three transparent support tubes through the three air intake holes. By analyzing the number and height of the floats, the training effectiveness of the patient's respiratory vital capacity can be determined. This provides a direct feedback on the training results, facilitating understanding of the patient's recovery status for both the patient and medical staff.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] This invention provides, for example Figures 1-8 The present invention is a respiratory training and respiratory rate feedback ventilator for COPD patients, including a ventilator base 1 and an air delivery tank 2. An auxiliary air delivery mechanism 3, a disinfection component 4 and a respiratory feedback component 7 are distributed on the inner and outer sides of the air delivery tank 2, respectively. The auxiliary gas delivery mechanism 3 includes an air inlet hopper 301 installed on one side of the top of the gas delivery tank 2. A first through groove 302 is opened on the top of the gas delivery tank 2 below the air inlet hopper 301. A first flow limiting plate 303 is installed on one end of the inner wall of the gas delivery tank 2. A second flow limiting plate 304 is installed on the inner wall of the first through groove 302. An air intake fan 305 is installed on the inner wall of the air inlet hopper 301. A pressure sensor 306 is installed on the other end of the inner wall of the gas delivery tank 2. A second through groove 307 is opened on one side of the bottom of the gas delivery tank 2. Multiple connecting grooves 308 are equally spaced on one side of the first flow limiting plate 303 and one side of the second flow limiting plate 304. A baffle plate 309 is rotatably connected to one side of the inner wall of each connecting groove 308. A torsion spring 310 is fixedly installed at both ends of each baffle plate 309. One end of each torsion spring 310 is fixedly connected to both sides of the inner wall of each connecting groove 308. In use, COPD patients connect the breathing end to their airway using a disposable mask 9, a second catheter 8, and rubber straps 10. During exhalation, the patient's exhaled air enters the air delivery canister 2 through the inlet tube 313 and is then blown onto the first flow restrictor 303. This causes the shielding plate 309 at the upper end of the first flow restrictor 303 to be pressed against it, closing the connecting groove 308 at its upper end. The exhaled air then enters the respiratory feedback assembly 7 below through the second passage 307 for feedback. The location of the second passage 307 is as shown in the instruction manual. Figure 3 As shown, the air canister 2 is positioned in front of the first flow-limiting plate 303, causing the patient's exhaled air to be completely directed downwards by the first flow-limiting plate 303. During inhalation, the patient draws away the airflow inside the air canister 2 that is in front of the first flow-limiting plate 303, thereby reducing the air pressure in front of the first flow-limiting plate 303. Under the pressure of the air pressure inside the air canister 2 located on the other side of the first flow-limiting plate 303, the upper baffle 309 is squeezed and rotated, thereby opening the connecting groove 308 on the first flow-limiting plate 303, allowing the airflow at the other end of the air canister 2 to be continuously drawn out. When the patient's breathing is obstructed, the change in air pressure suddenly drops, and when the sudden drop in air pressure reaches a certain range, the air pressure sensor 306 in the air canister 2 will detect this change, and then adjust the pressure through the wire 312. The upper intake fan 305 transmits a signal to start it. After the intake fan 305 starts, it blows the baffle 309 on the second flow limiter 304 to make it rotate and open the connecting groove 308 on the second flow limiter 304. This opens the passage of the first through groove 302, allowing external air to be introduced into the air delivery tank 2 through the air intake hopper 301 and the first through groove 302. The air then flows into the patient's respiratory tract to assist the patient's breathing. This avoids the risk of suffocation and shock caused by COPD complications during the patient's daily breathing training, thus improving the safety of COPD patients during breathing training. After the training is completed, the baffle 309 can be rotated to close the connecting groove 308 under the action of the torsion spring 310 at the upper end of the first flow limiter 303 and the second flow limiter 304. Furthermore, a dustproof plate 311 is installed on the upper edge of the inner wall of the air intake hopper 301. A wire 312 is inserted between one end of the air delivery tank 2 and one side of the air intake hopper 301. An air intake pipe 313 is inserted between the other end of the air delivery tank 2. The air pressure sensor 306 is electrically connected to the air intake fan 305 through the wire 312. The trigger range of the air pressure sensor 306 can be set by the pressure range caused by the sudden change in pressure inside the air delivery tank 2 when the patient has difficulty breathing. This trigger range is likely caused by the patient's difficulty breathing, so that the patient can be given auxiliary air in time to avoid suffocation caused by difficulty breathing. Furthermore, the disinfection component 4 includes an inlet tube 401 installed on one side of the top of the air delivery canister 2. A sealing valve 402 is installed on one side of the inlet tube 401. A third through groove 403 is opened on the top of the air delivery canister 2 below the inlet tube 401. After the breathing training is completed, in order to facilitate the use of the next patient, a sterilization bottle or a connecting tube for disinfection can be inserted into the inlet tube 401. At the same time, the sealing valve 402 is opened to introduce the disinfectant into the air delivery canister 2. Most ordinary disinfection equipment sprays out the disinfectant in a spray form. The disinfectant water mist flows in the air delivery canister 2 and is eventually discharged or evaporated, which disinfects the inside of the air delivery canister 2, making it convenient for the next patient to continue using it. This solves the problem of ordinary ventilators not being disinfected inside, which can easily cause cross-infection. Furthermore, the inner wall of the second through-slot 307 is connected to the first conduit 5, and the air intake base 6 is installed at the edge of the top side of the respirator base 1. One end of the first conduit 5 is connected to the inner wall of the air intake base 6. When the patient is breathing, after air is taken in through the air intake tube 313, the exhaled air is blocked by the first flow restrictor 303 and enters the air intake base 6 through the first conduit 5, and then enters the respiratory feedback component 7 for feedback. Furthermore, the respiratory feedback component 7 includes three transparent support tubes 701 that are equidistantly installed on the other side of the top of the ventilator base 1, and the tops of the three transparent support tubes 701 are fixedly connected to the bottom of the air delivery canister 2. An air delivery groove 702 is provided in the middle of the inner wall of the ventilator base 1. The inner wall of the air intake base 6 is connected to the air delivery groove 702 through the inner wall of the ventilator base 1, so that the patient's exhaled gas is introduced into the air delivery groove 702 through the first tube 5 and the air intake base 6.

[0023] The top of the respirator base 1 has air inlets 703 located below three transparent support tubes 701. The inner wall of each air inlet 703 is connected to the inner wall of the air guide groove 702. Floats 704 are inserted into the inner walls of each of the three transparent support tubes 701. Each float 704 has a vacuum groove 705 on its inner wall. Exhaled air flows in the air guide groove 702, sequentially entering each air inlet 703, and then into the upper transparent support tube 701. The greater the air intake, the stronger the air pressure at the bottom of the transparent support tube 701, causing the floats 704 to float within the transparent support tube 701. Based on the intensity of respiratory vital capacity, air sequentially enters the three transparent support tubes 701 through the three air inlets 703. By analyzing the number and height of the floats 704 that float, the training effectiveness of the patient's respiratory vital capacity can be determined. This provides a direct feedback on the training effectiveness, facilitating understanding of the patient's recovery status for both the patient and medical staff. (See the attached instruction manual.) Figure 7 As shown, each float 704 has a vacuum groove 705 inside, which greatly reduces its weight and makes it easier to blow it up when breathing; Furthermore, as per the instruction manual...Figure 8 As shown, a second tube 8 is inserted and connected to the inner wall of the air inlet tube 313. A mask 9 is fixedly connected to one end of the second tube 8, and the inner wall of one end of the second tube 8 is connected to the inner wall of the mask 9. A rubber strap 10 is fitted on the outer edge of the mask 9. The second tube 8, the mask 9, and the rubber strap 10 are all disposable items. They can be replaced when different patients use the ventilator to reduce the risk of cross-infection. At the same time, the mask 9 can be inserted and removed from the second tube 8. Patients with different usage habits can wear the mask 9 or blow directly into the second tube 8 for training.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
