Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a lung function monitoring device for lung injury. Background Technology

[0002] Pulmonary function tests are essential for the early detection of lung and airway lesions, assessment of disease severity and prognosis, evaluation of the efficacy of drugs or other treatments, identification of the cause of dyspnea, diagnosis of lesion location, assessment of lung function tolerance to surgery or labor intensity, and monitoring of critically ill patients.

[0003] A search revealed Chinese patent authorization announcement number CN105919598A, which discloses a portable lung function monitoring device based on Bluetooth transmission. The device includes a mouthpiece, a pressure detection device, and a main control unit. The mouthpiece is mounted on the front shell of a spring-loaded device. A ventilation hole is provided at the top of the front shell. The pressure detection device is installed inside the front shell. A main unit front shell and a main unit rear shell are mounted on one side of the pressure detection device. A spring-loaded rear shell retainer is provided on the main unit front shell. A conductive pin interface is provided below the spring-loaded rear shell retainer. A conductive pin is installed on the conductive pin interface. A display screen protective shell is installed on one side of the conductive pin. A button switch hole is provided above the display screen protective shell. A button switch shell is installed on the button switch hole. The advantages are: compact size, easy to carry, one-time payment for lifetime use, and simple operation. Users can perform measurements themselves, and the device can output measured values ​​and reference values, allowing users to understand their lung condition in a timely manner. Measurement results can be sent to a mobile phone for data analysis.

[0004] The purpose of requiring patients to pinch their noses during pulmonary function monitoring is to ensure the accuracy of the test. This prevents air leakage through the nose during exhalation, which would affect the measurement results. However, pinching the nose can lead to some patients not exhaling normally, and nasal leakage can reduce the amount of exhaled air, resulting in inaccurate measurements of parameters such as vital capacity and expiratory flow rate. On the other hand, not pinching the nose during testing may result in lower test results because some air will escape through the nose, reducing the amount of air entering the measurement system and also affecting the accuracy of the test results. Therefore, there is a need for a testing device that allows the patient's nose to be pinched during testing to improve the accuracy of the test. Utility Model Content

[0005] The purpose of this invention is to provide a pulmonary function monitoring device for lung injury, addressing the issues raised in the background section. The requirement for patients to pinch their noses during pulmonary function monitoring is primarily to ensure test accuracy, preventing air leakage through the nose during exhalation and thus affecting measurement results. However, pinching the nose can lead to some patients not exhaling normally, and nasal leakage reduces the amount of exhaled air, resulting in inaccurate measurements of vital capacity and expiratory flow rate. Conversely, not pinching the nose during testing may lead to lower test results because some air escapes through the nose, reducing the amount of air entering the measurement system and also affecting the accuracy of the test results.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to a lung function monitoring device for lung injury, comprising:

[0008] The monitoring component includes a detector body;

[0009] The nose clip assembly includes a limiting rod, a fixing plate, a threaded rod, a movable plate, a circular hole, a bearing, and a rubber block. The limiting rod is located on one side above the main body of the detector. The fixing plate is fixed to both ends of the outer surface of the limiting rod. The threaded rod is threaded through the middle of the fixing plate. The movable plate is connected to one side of the outer surface of the threaded rod. The circular hole is through one side of the outer surface of the movable plate and also through one side of the outer surface of the limiting rod. The bearing is installed on one side of the outer surface of the threaded rod. The rubber block is fixed to the inner side of one end of the movable plate.

[0010] Furthermore, the monitoring component also includes a display screen, a control button, and an air inlet. The display screen is fixed to one side of the outer surface of the detector body, the control button is fixed to the upper end of one side of the outer surface of the detector body, and the air inlet is fixed to the upper end of one side of the detector body.

[0011] Furthermore, a fixing frame is fixed on the upper surface of the detector body, a first rotating shaft passes through the inside of the fixing frame, and a first connecting rod passes through the outer surface of the first rotating shaft.

[0012] Furthermore, a mounting groove is provided at one end of the outer surface of the first connecting rod, a second rotating shaft passes through the outer surface of the mounting groove, and the second connecting rod rotatably passes through the outer surface of the second rotating shaft.

[0013] Furthermore, the outer surface of the second connecting rod extends through the limit rod, and one side of the outer surface of the bearing is fixed to the middle of the moving plate.

[0014] Furthermore, it also includes a fixing component, which includes a fixing block, a through hole, and a movable rod. The fixing block is fixed on both sides of the upper surface of the detector body, the through hole is opened in the middle of the upper part of the outer surface of the fixing block, and the movable rod passes through the inside of the through hole.

[0015] Furthermore, the fixing assembly also includes a baffle, a spring, and a locking block. The baffle is fixed to one side of the outer surface of the movable rod, the spring passes through the outer surface of the movable rod, and the locking block is fixed to the other side of the outer surface of the movable rod, with the spring located in the middle of the fixing block and the locking block.

[0016] Furthermore, a slanted groove is formed on one side of the outer surface of the card block, with one end of the slanted groove being lower than the other end.

[0017] Compared with existing technologies, the advantages of this utility model are:

[0018] I. This utility model, through its monitoring components and nose clip assembly, allows the patient to first place their mouth over the air inlet before lung function testing. Then, the first and second connecting rods are rotated, placing rubber blocks on either side of the patient's nose. Next, medical personnel rotate the threaded rod within the fixed plate, causing the moving plate to move within the limiting rod, thus moving the rubber blocks to the patient's nose. The rotation of the threaded rod clamps the rubber blocks tightly around the patient's nose. For some patients, such as children, the elderly, or those with weakened constitutions, manually pinching the nose can be difficult, thus this invention helps reduce the workload of medical personnel and improves the accuracy of the test.

[0019] II. Based on the first beneficial effect, by setting up a fixed component, when testing is not required, the operator can rotate the threaded rod in the opposite direction to open the rubber block from both sides of the patient's nose. Then, the first connecting rod is rotated to the other side to make the first connecting rod contact the locking block. Under the guidance of continuous rotation and the inclined groove, the movable rod moves outward in the through hole, compressing the spring and moving the locking block to both sides. When the first connecting rod moves to the underside of the locking block, the spring will quickly return to its original deformation, and the movable rod will move to the middle, so that the locking block fixes the first connecting rod. Through the automatic release and locking mechanism, the time and labor of manual operation can be saved, and the efficiency of equipment use can be improved. Attached Figure Description

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0033] Please see Figures 1 to 4 As shown, this embodiment is a lung function monitoring device for lung injury, comprising:

[0034] The monitoring component includes a detector body 11, a display screen 12, a control button 13, and an air outlet 14. The display screen 12 is fixed to one side of the outer surface of the detector body 11, the control button 13 is fixed to the upper end of one side of the outer surface of the detector body 11, and the air outlet 14 is fixed to the upper end of one side of the detector body 11.

[0035] The main body 11 of the detector is the basic structure of the entire monitoring component. All other components are fixed or mounted on it. The air inlet 14 is used for patients to perform exhalation tests and detect indicators such as lung function.

[0036] The nose clip assembly includes a limiting rod 231, a fixing plate 24, a threaded rod 25, a movable plate 26, a circular hole 27, a bearing 28, and a rubber block 29. The limiting rod 231 is located on the upper side of the detector body 11. The fixing plate 24 is fixed to both ends of the outer surface of the limiting rod 231. The threaded rod 25 is threaded through the middle of the fixing plate 24. The movable plate 26 is connected to one side of the outer surface of the threaded rod 25. The circular hole 27 is through one side of the outer surface of the movable plate 26 and also through one side of the outer surface of the limiting rod 231. The bearing 28 is installed on one side of the outer surface of the threaded rod 25. The rubber block 29 is fixed to the inner side of one end of the movable plate 26.

[0037] The limiting rod 231 is fixed in position, limiting the movement range of the moving plate 26. The fixed plate 24 serves as a basic support, fixing the limiting rod 231. The threaded rod 25 rotates and is connected to the fixed plate 24 through the thread, driving the moving plate 26 to move. The moving plate 26 cooperates with the limiting rod 231 through the circular hole 27 on it to achieve position adjustment. The rubber block 29 clamps the patient's nose to prevent air leakage from the nose during blowing.

[0038] A fixing frame 21 is fixed on the upper surface of the detector body 11. A first rotating shaft 211 passes through the inside of the fixing frame 21. A first connecting rod 22 passes through the outer surface of the first rotating shaft 211. A mounting groove 221 is opened at one end of the outer surface of the first connecting rod 22. A second rotating shaft 222 passes through the outer surface of the mounting groove 221. A second connecting rod 23 passes through the outer surface of the second rotating shaft 222. A limit rod 231 passes through the outer surface of the second connecting rod 23. One side of the outer surface of the bearing 28 is fixed to the middle of the moving plate 26.

[0039] The fixed frame 21 is used to fix the first rotating shaft 211. The first connecting rod 22 cooperates with the second rotating shaft 222 through the mounting groove 221 on it to transmit rotational motion. The second connecting rod 23 cooperates with the nose clip assembly through the limiting rod 231 on it to realize the overall movement and positioning.

[0040] Working principle:

[0041] Before testing lung function, the patient first puts their mouth over the mouth opening 14, then rotates the first connecting rod 22 and the second connecting rod 23, and places the rubber block 29 on both sides of the patient's nose. Then, the medical staff rotates the threaded rod 25, which rotates within the fixed plate 24, causing the moving plate 26 to move within the limiting rod 231, moving the rubber block 29 to the patient's nose. Under the rotation of the threaded rod 25, the rubber block 29 clamps the patient's nose.

[0042] This step, which can be difficult for some patients such as children, the elderly, or those who are physically weak, helps reduce the workload of healthcare workers and improve the accuracy of testing.

[0043] Please see Figures 1 to 4 As shown; this embodiment, based on embodiment 1 above, further includes:

[0044] The fixing assembly includes a fixing block 31, a through hole 32, and a movable rod 33. The fixing block 31 is fixed on both sides of the upper surface of the detector body 11. The through hole 32 is opened in the middle of the upper part of the outer surface of the fixing block 31. The movable rod 33 passes through the inside of the through hole 32. The fixing assembly also includes a baffle 331, a spring 34, and a locking block 35. The baffle 331 is fixed on one side of the outer surface of the movable rod 33. The spring 34 passes through the outer surface of the movable rod 33. The locking block 35 is fixed on the other side of the outer surface of the movable rod 33. The spring 34 is located in the middle of the fixing block 31 and the locking block 35. A groove 36 is opened on one side of the outer surface of the locking block 35. One end of the groove 36 is lower than the other end.

[0045] The fixing block 31 is the basic structure of the entire fixing assembly, used to provide stable support and mounting points. The baffle 331 is used to limit the range of movement of the movable rod. The spring 34 provides elastic force when released, so that the locking block 35 can quickly return to its original position. The locking block 35 is the key component to realize the locking function. When the movable rod 33 moves, the locking block 35 will move accordingly, thereby realizing the locking or releasing of the first connecting rod 22.

[0046] Working principle:

[0047] When no testing is required, the operator rotates the threaded rod 25 in the opposite direction to open the rubber block 29 from both sides of the patient's nose. Then, the first connecting rod 22 is rotated to the other side to make the first connecting rod 22 contact the locking block 35. Under the guidance of continuous rotation and the inclined groove, the movable rod 33 moves outward in the through hole 32, compressing the spring 34 and moving the locking block 35 to both sides. When the first connecting rod 22 moves to the underside of the locking block 35, the spring 34 will quickly return to its original shape, and the movable rod 33 will move towards the middle, so that the locking block 35 fixes the first connecting rod 22.

[0048] This step, through an automatic release and locking mechanism, can save time and labor from manual operation and improve the efficiency of equipment use.
