Description

Technical Field

[0001] This invention relates to the field of respiratory training technology, and more specifically to a lung recruitment and breathing training device. Background Technology

[0002] Currently, patients in intensive care units who require long-term endotracheal intubation for respiratory support and those who have undergone thoracic lung surgery have a high incidence of postoperative atelectasis, prolonging hospital stays and increasing the burden on patients. Clinicians often administer oxygen or increase the oxygen concentration, but oxygen administration does not increase ventilation; in fact, the high oxygen content can decrease ventilation. Insufficient ventilation cannot prevent alveolar collapse, nor can it re-expand collapsed alveoli. Deep and slow abdominal breathing is the ideal breathing pattern after open-chest surgery; however, patient compliance with respiratory function exercises is poor in clinical practice. Only through active pulmonary function exercises can lung ventilation be increased, thus playing a role in preventing and treating pulmonary complications.

[0003] In existing technologies, active lung function training is generally conducted through breathing training devices. For example, patent CN213965033U discloses a simple respiratory function rehabilitation device, including a transparent bottle. The interior of the bottle is divided into a gas chamber and a liquid chamber by a partition. Both the gas and liquid chambers have upward-protruding connecting parts at their tops. Two connecting tubes are inserted into each connecting part, and the connecting tubes on different connecting parts are connected by short tubes. The lower end of the other connecting tube located on the liquid chamber extends downward into the liquid chamber. A long tube is fitted onto the other connecting tube located on the gas chamber. When using this device, patients can directly see the effectiveness of their inhalation, thus enabling them to better perform respiratory function training, promote lung re-expansion, and improve lung function.

[0004] However, when using this device for breathing training, patients cannot clearly see the goals of the training, which may lead to overtraining or undertraining. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is that when performing breathing training, patients cannot intuitively understand the goal of breathing training, which may lead to over-training or under-training.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a lung recruitment and breathing training device, comprising:

[0007] A transparent container, wherein the transparent container is provided with an air intake hole;

[0008] A water storage cavity is installed below the transparent tank.

[0009] A water inlet pipe, one end of which is installed inside a water storage cavity, and the other end of which is installed inside a transparent tank, wherein the water storage cavity is connected to the transparent tank via the water inlet pipe; and

[0010] A siphon tube is located inside a transparent tank. One end of the siphon tube is located at the bottom of the transparent tank, and the other end of the siphon tube is installed on and connected to the inlet pipe. The flow from the end of the siphon tube at the bottom of the transparent tank to the other end of the siphon tube is unidirectional. The height of the end of the siphon tube at the bottom of the transparent tank is less than the height of the other end of the siphon tube. Furthermore, the height of the end of the inlet pipe inside the transparent tank is greater than the height of the end of the siphon tube installed on the inlet pipe.

[0011] In this invention, the patient inhales through the inhalation port on the transparent container. Under negative pressure, water from the storage chamber enters the transparent container through the inlet pipe. The patient then exhales after separating their mouth from the inhalation port, thus exercising their respiratory function, promoting lung re-expansion, and improving lung function. Continuous inhalation ensures a continuous flow of water into the transparent container, allowing for sustained exercise. When the water in the transparent container reaches the highest point of the siphon tube, the water is drained into the storage chamber through the siphon tube. This completes the breathing training, allowing the patient to clearly understand the training goals and perform regular, quantitative breathing exercises daily, thereby improving the training effect.

[0012] Preferably, the height of the siphon tube installed on the inlet pipe is adjustable. This allows adjustment of the highest position of the siphon tube within the transparent container, thereby regulating the amount of breathing training the patient receives daily.

[0013] Preferably, the inlet pipe includes a connecting pipe, a sliding pipe, and an adjusting component; one end of the connecting pipe passes through the transparent tank and extends into the water storage cavity, and the connecting pipe is fixedly connected to the transparent tank; one end of the sliding pipe extends into the connecting pipe, and the other end of the sliding pipe is located in the transparent tank and communicates with the transparent tank, and the sliding pipe can slide along the length of the connecting pipe; the adjusting component can adjust the sliding distance of the sliding pipe; the end of the siphon tube away from the bottom of the transparent tank is installed on the sliding pipe, and the length of the siphon tube is adjustable. The adjusting component controls the sliding of the sliding pipe, and the sliding pipe drives the end of the siphon tube installed on the sliding pipe to move, causing the siphon tube to lengthen or shorten, thereby adjusting the highest position of the siphon tube in the transparent tank, and realizing the adjustment of the patient's daily breathing training volume.

[0014] Preferably, the adjusting component includes a threaded rod and a knob; the threaded rod passes through the transparent tank and is threadedly connected to it, the threaded rod is arranged along the sliding direction of the sliding tube, one end of the threaded rod is rotatably connected to the sliding tube, and the other end of the threaded rod is equipped with a knob. The knob drives the threaded rod to rotate, causing the threaded rod to move, thereby driving the sliding tube to move, thus adjusting the sliding distance of the sliding tube.

[0015] Preferably, the siphon tube includes a corrugated pipe, a connector, a fixing head, and a first one-way valve; one end of the corrugated pipe is connected to a sliding pipe through the connector, and the other end of the corrugated pipe is connected to the bottom of the transparent tank through the fixing head, and the fixing head is fixedly connected to the transparent tank; the first one-way valve is installed on the connector. The length of the siphon tube is adjustable through the telescopic function of the corrugated pipe; the first one-way valve enables unidirectional flow from the end of the siphon tube located at the bottom of the transparent tank to the other end of the siphon tube.

[0016] Preferably, the connecting tube is equipped with an adjusting valve, which can adjust the cross-sectional area of ​​the connecting tube. By adjusting the cross-sectional area of ​​the connecting tube with the adjusting valve, the force of the patient's inhalation can be controlled.

[0017] Preferably, it also includes an air suction tube, one end of which is connected to the transparent canister through an air suction hole. The air suction tube makes air intake more convenient.

[0018] Preferably, the suction pipe is provided with an exhaust port; the suction pipe is also provided with a second one-way valve, which restricts air intake into the transparent tank through the suction pipe, and is located between the exhaust port and the suction port. The second one-way valve ensures that the suction pipe can only draw air outwards and cannot blow air into the transparent tank, thus effectively preventing the pressure inside the transparent tank from increasing after air is blown in, which would cause the water inside the transparent tank to drain into the storage chamber through the siphon pipe.

[0019] Preferably, a rubber tip is installed at the end of the inhalation tube furthest from the inhalation port. This allows for a closer fit between the tube and the patient's mouth during breathing exercises, effectively preventing air leakage due to gaps between the patient's mouth and the inhalation tube.

[0020] Preferably, the water storage cavity is provided with an air inlet to balance the pressure inside the water storage cavity.

[0021] Compared with the prior art, the present invention has at least the following advantages:

[0022] 1. Patients can clearly and intuitively understand the goals of breathing training. In this invention, patients inhale through the inhalation port on the transparent container. Under negative pressure, water in the storage chamber enters the transparent container through the inlet pipe. Then, the patient exhales after separating their mouth from the inhalation port, thus exercising respiratory function, promoting lung re-expansion, and improving lung function. Through continuous inhalation, water continuously enters the transparent container from the storage chamber, achieving continuous training for the patient. When the water in the transparent container submerges the highest point of the siphon tube, the water in the transparent container is drained into the storage chamber through the siphon tube. This completes the breathing training, allowing patients to clearly and intuitively understand the goals of breathing training, enabling them to perform breathing training regularly and quantitatively each day, thereby improving the training effect.

[0023] 2. By adjusting the cross-sectional area of ​​the connecting tube through the regulating valve, the strength of the patient's inhalation can be controlled. Attached Figure Description

Detailed Implementation

[0028] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0029] In this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0030] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0031] See Figures 1-2 The present invention provides an embodiment of a lung recruitment breathing trainer, comprising: a transparent tank 1, a water storage chamber 2, a water inlet pipe 3, and a siphon tube; the transparent tank 1 is provided with an air inlet 11; specifically, the transparent tank 1 can be made of glass; the water storage chamber 2 is installed below the transparent tank 1; further, the water storage chamber 2 is provided with an air inlet 21 to balance the pressure inside the water storage chamber 2; one end of the water inlet pipe 3 is installed inside the water storage chamber 2, and the other end of the water inlet pipe 3 is installed inside the transparent tank 1, and the water storage chamber 2 is connected to the transparent tank 1 through the water inlet pipe 3; the siphon tube is located inside the transparent tank 1, one end of the siphon tube is located at the bottom of the transparent tank 1, and the other end of the siphon tube is installed on and connected to the water inlet pipe 3, and the siphon tube is located inside the transparent tank 1. The transparent tank 1 has a one-way flow from one end at the bottom to the other end of the siphon tube. This prevents water in the inlet pipe 3 from entering the transparent tank 1 through the siphon tube during air intake, causing the siphon tube to fill with water. When air intake stops and the water in the transparent tank 1 exceeds the highest point of the siphon tube, the water in the siphon tube forms a negative pressure under gravity, draining the water from the transparent tank 1 into the storage chamber 2 through the siphon tube. The height of the siphon tube at the bottom of the transparent tank 1 is less than the height of the other end of the siphon tube. This ensures that water can remain in the transparent tank 1 when the water level in the transparent tank 1 has not reached the highest point of the siphon tube during air intake. Furthermore, the height of the inlet pipe 3 inside the transparent tank 1 is greater than the height of the siphon tube installed on the inlet pipe 3. This prevents water in the transparent tank 1 from being discharged from the end of the inlet pipe 3 inside the transparent tank 1 when the water level in the transparent tank 1 has not reached the highest point of the siphon tube.

[0032] In practice, the water storage chamber 2 contains water. The patient inhales through the inhalation port 11 on the transparent container 1. Under negative pressure, the water in the water storage chamber 2 enters the transparent container 1 through the inlet pipe 3. Then, the patient exhales after separating their mouth from the inhalation port 11, thus exercising their respiratory function, promoting lung re-expansion, and improving lung function. Through continuous inhalation, water continuously enters the transparent container 1 from the water storage chamber 2, enabling continuous exercise for the patient. When the water in the transparent container 1 submerges the highest point of the siphon tube, the water in the transparent container 1 is drained into the water storage chamber 2 through the siphon tube. This completes the breathing training, allowing the patient to clearly understand the goal of the breathing training and enabling them to perform breathing training regularly and quantitatively each day, thereby improving the training effect.

[0033] See Figures 1-2 In other embodiments, the height of one end of the siphon tube mounted on the inlet pipe 3 is adjustable. This allows adjustment of the highest position of the siphon tube within the transparent container 1, thereby enabling adjustment of the amount of breathing training the patient receives daily.

[0034] See Figures 1-2 In other embodiments, the inlet pipe 3 includes a connecting pipe 31, a sliding pipe 32, and an adjusting component. One end of the connecting pipe 31 passes through the transparent tank 1 and extends into the water storage cavity 2, and the connecting pipe 31 is fixedly connected to the transparent tank 1. One end of the sliding pipe 32 extends into the connecting pipe 31, and the other end of the sliding pipe 32 is located inside the transparent tank 1 and communicates with the transparent tank 1. The sliding pipe 32 can slide along the length of the connecting pipe 31. The adjusting component can adjust the sliding distance of the sliding pipe 32. The end of the siphon tube away from the bottom of the transparent tank 1 is installed on the sliding pipe 32, and the length of the siphon tube is adjustable. In specific implementation, the adjusting component is controlled to slide the sliding pipe 32. The sliding pipe 32 drives the end of the siphon tube installed on the sliding pipe 32 to move, so that the siphon tube is lengthened or shortened, thereby adjusting the highest position of the siphon tube inside the transparent tank 1, and realizing the adjustment of the amount of daily breathing training for the patient.

[0035] See Figures 1-2 In other embodiments, the adjusting component includes a threaded rod 33 and a knob 34. The threaded rod 33 passes through and is threadedly connected to the transparent tank 1. The threaded rod 33 is arranged along the sliding direction of the sliding tube 32, and one end of the threaded rod 33 is rotatably connected to the sliding tube 32. The other end of the threaded rod 33 is equipped with a knob 34. In specific implementation, rotating the knob 34 causes the threaded rod 33 to rotate, thereby moving the threaded rod 33 and causing the sliding tube 32 to move, thus adjusting the sliding distance of the sliding tube 32.

[0036] See Figures 1-2 In other embodiments, the siphon tube includes a bellows 41, a connector 42, a fixing head 43, and a first one-way valve 44. One end of the bellows 41 is connected to the sliding tube 32 via the connector 42, and the other end of the bellows 41 is connected to the bottom of the transparent tank 1 via the fixing head 43, with the fixing head 43 fixedly connected to the transparent tank 1. The first one-way valve 44 is mounted on the connector 42. The length of the siphon tube is adjustable through the telescopic function of the bellows 41; the first one-way valve 44 enables one-way flow from the end of the siphon tube located at the bottom of the transparent tank 1 to the other end of the siphon tube.

[0037] See Figures 1-2 In other embodiments, a regulating valve 35 is installed on the connecting pipe 31, which can adjust the cross-sectional area of ​​the connecting pipe 31. By adjusting the cross-sectional area of ​​the connecting pipe 31 through the regulating valve 35, the force of the patient's inhalation can be controlled. Specifically, the regulating valve 35 is a manual ball valve, and for easy adjustment, the rotating end of the manual ball valve extends to the outside of the water storage cavity 2.

[0038] See Figures 1-2 In another embodiment, an inhalation tube 5 is also included, one end of which is connected to the transparent container 1 via an inhalation hole 11. The inhalation tube 5 facilitates easier inhalation. Furthermore, the inhalation tube 5 is provided with an exhaust hole 51; a second one-way valve 52 is also provided on the inhalation tube 5, restricting airflow from the inhalation tube 5 into the transparent container 1, and the second one-way valve 52 is located between the exhaust hole 51 and the inhalation hole 11. The second one-way valve 52 ensures that the inhalation tube 5 can only inhale outwards, preventing air from being blown into the transparent container 1. This effectively avoids increasing the pressure inside the transparent container 1 after air is blown in, thus preventing water in the transparent container 1 from being drained into the water storage chamber 2 through a siphon tube. Simultaneously, when the patient exhales, the gas enters the inhalation tube 5 and is discharged through the exhaust hole 51, without entering the transparent container 1; and when inhaling, the patient only needs to block the exhaust hole 51 with their finger. Furthermore, a rubber head 53 is installed at the end of the inhalation tube 5 away from the inhalation port 11. This allows for a closer fit between the tube and the patient's mouth during breathing exercises, effectively preventing air leakage due to gaps between the patient's mouth and the inhalation tube 5.

[0039] See Figures 1-2In another embodiment, pressure sensors are respectively installed at the exhaust port 51 and the air inlet 21. The pressure sensors collect the air pressure values ​​at the exhaust port 51 and the air inlet 21, thereby enabling the measurement and analysis of the patient's maximum expiratory pressure and maximum inspiratory pressure. This facilitates the analysis of the patient's baseline condition and treatment progress, accurately measures the patient's respiratory capacity level, and prevents the patient's breathing training from exceeding the patient's baseline condition. Therefore, the patient's maximum expiratory pressure and maximum inspiratory pressure are measured and analyzed to accurately assess the patient's baseline respiratory capacity level.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. 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 or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
