Description

Technical Field

[0001] This invention belongs to the field of clinical nursing technology, specifically relating to a lung capacity training device with dynamic data feedback. Background Technology

[0002] After thoracic or abdominal surgery, wound pain can cause patients to restrict chest movement and adopt a shallow, rapid breathing pattern, which further exacerbates pulmonary insufficiency. Specific breathing exercises (such as diaphragmatic breathing) can help relax muscles, manage pain more effectively, and increase lung capacity and oxygenation: through deep breathing exercises, the lungs can be expanded to the maximum extent, improving the ventilation / perfusion ratio, increasing the oxygen content in the blood, and providing sufficient oxygen for tissue repair and physical recovery.

[0003] For example, Chinese Patent Publication No. CN 220175985 U discloses an inhalation training device for respiratory rehabilitation with data recording and analysis functions. This device includes a training mechanism comprising a base plate, a training cylinder, a piston plate, an inhalation tube, a data analyzer, and a rangefinder. The training cylinder is fixedly connected to the top surface of the base plate, the piston plate is slidably connected to the top surface of the training cylinder, the inhalation tube is fixedly inserted into the side of the training cylinder, the data analyzer is located on the top surface of the base plate, and the rangefinder is located on the inner wall of the training cylinder. The rangefinder is electrically connected to the data analyzer. This device uses a motor to drive a transmission rod and a turntable assembly to rotate, thereby causing the hooks to sequentially separate from the tension spring assembly, thus reducing the resistance when the piston plate moves. Therefore, adjusting the training volume of the training cylinder is more convenient.

[0004] As described in the prior art of the aforementioned patent, although resistance can be adjusted, it is inconvenient to record the duration of each patient's exhalation and to compare the exhalation duration with the amount of exhaled air. Utility Model Content

[0005] The purpose of this invention is to provide a lung capacity training device with dynamic data feedback, which can monitor and sense the duration of a patient's exhalation, thereby determining the relationship between respiratory duration and lung capacity.

[0006] The specific technical solution adopted in this utility model is as follows: A lung capacity training device with dynamic data feedback includes an air collection cylinder. The lower end of the air collection cylinder is connected to an air inlet pipe and an air outlet pipe. The upper end of the air inlet pipe is connected to an air inlet cylinder one, and an air inlet cylinder two is located at the front end of the air inlet cylinder one. A plug is slidably disposed inside the air inlet cylinder one. A baffle is located at the front end of the plug, and a guide rod is connected to the rear end of the plug. The guide rod is slidably disposed at the rear end of the air inlet cylinder one, and a spring is sleeved on the guide rod. A laser emitter and a laser receiver are respectively disposed on both sides of the air inlet cylinder two. When no air is being blown into the air inlet cylinder two, the baffle is positioned between the laser emitter and the laser receiver, and the plug is positioned at the connection between the air inlet cylinder one and the air inlet cylinder two, maintaining a closed state. The laser emitter and the laser receiver are electrically connected to a control device.

[0007] In a preferred embodiment, the front end of the second air intake cylinder is snapped with an air intake nozzle.

[0008] In a preferred embodiment, a piston is slidably mounted inside the gas collecting cylinder, a connecting rod is connected to the upper end of the piston, a top plate is mounted on the top of the connecting rod, a rangefinder is mounted on the side of the top plate, a rangefinder receiver is mounted below the rangefinder, and the rangefinder receiver is fixedly mounted on the top of the gas collecting cylinder.

[0009] In a preferred embodiment, a control valve is installed on the exhaust pipe.

[0010] In a preferred embodiment, the inner diameter of the first air intake cylinder is larger than the inner diameter of the second air intake cylinder, the outer diameter of the plug is larger than the inner diameter of the second air intake cylinder, and the outer diameter of the plug is smaller than the inner diameter of the first air intake cylinder.

[0011] In a preferred embodiment, the control device is electrically connected to both the rangefinder and the rangefinder receiver.

[0012] The technical effects achieved by this utility model are as follows: In this application, when no air is blown into the second air inlet, the baffle is positioned between the laser transmitter and the laser receiver. When air is blown into the second air inlet, the gas pushes the blockage away from the second air inlet, simultaneously moving the baffle. This allows the signal emitted by the laser transmitter to be received by the laser receiver. When the laser transmitter and laser receiver establish a signal connection, the signal is transmitted to the control device for analysis and timing. This allows the recording of the patient's exhalation duration. Furthermore, the exhaled air is collected by the air collection cylinder, allowing for observation and measurement of the exhaled air volume, providing real-time feedback on the patient's lung tension status.

[0015] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0016] Many specific details are set forth in the following description in order to provide a full understanding of this utility model. However, this utility model may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0017] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of this utility model. The phrase "in a preferred embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments.

[0018] Secondly, this utility model is described in detail with reference to the schematic diagrams. When detailing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0019] Please see the appendix Figures 1 to 4As shown, this utility model provides a lung capacity training device with dynamic data feedback, including an air collection cylinder 1. The lower end of the air collection cylinder 1 is connected to an air inlet pipe 2 and an air outlet pipe 3. The upper end of the air inlet pipe 2 is connected to an air inlet cylinder 21, and an air inlet cylinder 22 is provided at the front end of the air inlet cylinder 21. A plug 24 is slidably disposed inside the air inlet cylinder 21. A baffle 241 is provided at the front end of the plug 24, and a guide rod 242 is connected to the rear end of the plug 24. The guide rod 242 is slidably disposed at the rear end of the air inlet cylinder 21, and a spring 243 is sleeved on the guide rod 242. Laser emitter 5 and laser receiver 6 are respectively installed on both sides of the second air inlet 22. When no air is blown into the second air inlet 22, the baffle 241 is exactly between the laser emitter 5 and the laser receiver 6, and the plug 24 is blocked at the connection between the first air inlet 21 and the second air inlet 22, keeping it in a closed state. The laser emitter 5 and the laser receiver 6 are electrically connected to the control device 4 respectively. The inner diameter of the first air inlet 21 is larger than the inner diameter of the second air inlet 22, and the outer diameter of the plug 24 is larger than the inner diameter of the second air inlet 22, while the outer diameter of the plug 24 is smaller than the inner diameter of the first air inlet 21. During lung capacity training, due to the elastic force of spring 243 (a constant force spring can be used to improve the service life of spring 243 and match the resistance when the blockage 24 moves), when no air is blown into the second air inlet 22, the blockage 24 is located at the connection between the first air inlet 21 and the second air inlet 22, in a closed state. Furthermore, the baffle 241 connected to the front end of the blockage 24 is positioned between the laser transmitter 5 and the laser receiver 6, thus disconnecting their signals. When the patient blows air into the second air inlet 22, the air pushes the blockage 244... 4. The air flows along the second air intake 22 to the first air intake 21, and then along the air intake pipe 2 into the collecting cylinder 1 where it is collected. When the blockage 24 is pushed, it will also move the baffle 241, so that the baffle 241 will no longer block the laser emitter 5 and the laser receiver 6. The laser signal emitted by the laser emitter 5 is received by the laser receiver 6, so that the two are connected. Then the signal is transmitted to the control device 4. After analysis and timing by the control device 4, the duration of the patient's exhalation can be calculated, and the patient's breathing can be fed back in real time.

[0020] The front end of the second air inlet cylinder 22 is connected to the air inlet nozzle 23. In this application, the air inlet nozzle 23 is snapped into the second air inlet cylinder 22, so that the air inlet nozzle 23 and the second air inlet cylinder 22 can be disassembled, making it convenient for one patient to replace one air inlet nozzle 23 and avoiding cross-infection.

[0021] Please see Figure 3As shown, a piston 11 is slidably mounted inside the air collecting cylinder 1. A connecting rod 12 is connected to the upper end of the piston 11. A top plate 13 is installed at the top of the connecting rod 12. A rangefinder 14 is installed on the side of the top plate 13. A rangefinder receiver 15 is installed below the rangefinder 14. The rangefinder receiver 15 is fixedly installed at the top of the air collecting cylinder 1. The control device 4 is electrically connected to both the rangefinder 14 and the rangefinder receiver 15. In this embodiment, the air inlet pipe 2 and the exhaust pipe 3 are respectively connected to the lower end of the air collection cylinder 1. When the patient is training to exhale, the piston 11 is first pushed to the bottom of the air collection cylinder 1. When the exhaled air enters the air collection cylinder 1 through the air inlet pipe 2, it will push the piston 11 upward. When the piston 11 moves upward, it will drive the connecting rod 12 to extend upward, and then the top plate 13 and the rangefinder 14 will move upward, so that the distance between the rangefinder 14 and the rangefinder receiver 15 changes. Knowing the inner diameter of the air collection cylinder 1, the distance that the piston 11 moves from the bottom to the top can be calculated by measuring the distance of the piston 11 from the bottom through the rangefinder 14 and the rangefinder receiver 15. The volume of air exhaled by the patient in one breath can be calculated, and then the patient's vital capacity can be determined. In this application, when the piston 11 is at the bottom of the air collecting cylinder 1, the distance between the rangefinder 14 and the range receiver 15 is set to zero, and the distance measurement signals between the rangefinder 14 and the range receiver 15 are transmitted to the control device 4 for analysis and display.

[0022] A control valve 31 is installed on the exhaust pipe 3. In this application, when the patient is performing breathing training, the control valve 31 is in a closed state. After one breathing training session, the control valve 31 is opened, and the piston 11 and the distance receiver 15 are pushed down by pressing the top plate 13, so that the exhaled gas is discharged through the exhaust pipe 3, which facilitates the next breathing training session.

[0023] In this embodiment, the control device 4 is electrically connected to the laser emitter 5, the laser receiver 6, the rangefinder 14, and the range receiver 15. The control methods are all existing technologies and will not be described in detail here.

[0024] The working principle of this utility model is as follows: When performing lung capacity training on a patient, due to the elastic force of the spring 243, when no air is blown into the second air inlet 22, the block 24 is blocked at the connection between the first air inlet 21 and the second air inlet 22, and is in a closed state. Furthermore, the baffle 241 connected to the front end of the block 24 is positioned between the laser emitter 5 and the laser receiver 6, thus disconnecting the signals between the two. When the patient blows air into the second air inlet 22, the air pushes the blockage 24, travels along the second air inlet 22 to the first air inlet 21, and then enters the collecting cylinder 1 through the air inlet pipe 2 to be collected. When the blockage 24 is pushed, it also moves the baffle 241, causing the baffle 241 to no longer block the laser emitter 5 and the laser receiver 6. The laser signal emitted by the laser emitter 5 is received by the laser receiver 6, making the two connected. The signal is then transmitted to the control device 4, which analyzes and times the signal to calculate the duration of the patient's exhalation and provide real-time feedback on the patient's breathing.

[0025] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the art.
