Description

TECHNICAL FIELD

[0001] The application belongs to the field of clinical internal medicine, in particular to a respiratory exercise testing device for clinical internal medicine. BACKGROUND

[0002] Internal medicine is a specialty of clinical medicine, and is the basis of almost all other clinical medicine, and is also known as the mother of medicine. The content of internal medicine includes the definition, cause, pathogenesis, epidemiology, natural history, symptoms, signs, experimental diagnosis, imaging examination, differential diagnosis, diagnosis, treatment and prognosis of diseases. When a person inhales normally, the diaphragm contracts and the external intercostal muscles contract. When inhaling with force, the inspiratory auxiliary muscles such as the trapezius and the oblique muscles are also needed. The contraction of these muscles results in the elevation of the chest and the expansion of the chest cavity to the limit, so the inspiratory muscles need to be exercised.

[0003] For example, in the Chinese patent with publication number CN114452619B, a respiratory exercise testing device for clinical internal medicine is mentioned, which includes a shell, a breathing tube, and a pair of holding grips. The breathing tube is connected to one side of the shell, and a pair of holding grips are welded to one side of the shell. A piston-type respiratory exercise testing structure is arranged in the shell. A breathing filter mechanism is arranged on one side of the shell and is in communication with the respiratory exercise testing structure. A digital display structure is arranged on the other side of the respiratory exercise testing structure. The beneficial effects of the present application are that the respiratory exercise testing device for clinical internal medicine integrates a pressure sensing detection system and a piston-type reciprocating structure, which enriches the functions of the respiratory exercise testing device. At the same time, it is equipped with a filter system to effectively filter out bacteria and moisture in exhaled air, avoid pollution of the equipment, and cooperate with the digital display structure to make the exercise data visualized, which can greatly help doctors to judge the exercise effect and improve the diagnosis and treatment efficiency.

A wire is provided at the end of the pressure sensor away from the compression spring.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. This invention connects the indwelling tube to its inlet and secures it with a buckle on the inlet surface. Then, a second clamp is pressed according to the tube's diameter, causing the second clamp to compress a second spring, which in turn generates a reaction force, thus securing the indwelling tube and preventing displacement. Simultaneously, the indwelling tube is connected to its outlet and secured with a buckle on the outlet surface. Conversely, a first clamp is pressed according to the tube's diameter, causing the first clamp to compress a first spring, which in turn generates a reaction force, securing the indwelling tube. This invention allows the device to meet the needs of patients with indwelling tubes, enhancing its practicality.

[0019] 2. This invention connects the oxygen outlet of the oxygen concentrator to an oxygen pipeline, enabling the device to meet oxygen supply needs. The patient's exhaled waste gas is filtered through the breathing plate and filter screen, preventing insufficient oxygen supply during breathing exercises. When breathing exercises are needed, the oxygen inlet is cut off, and the pull plate is pulled down, causing the plate to move the placement plate, which in turn moves the fixing plate and the breathing tube, stretching the corrugated tube. The patient then bites down on the breathing tube and exhales. The exhaled gas passes through the filter screen, filter element, and absorbent cotton in the filtration assembly, filtering out the water exhaled by the patient. The system filters the steam and exhaust gas. The exhaled gas compresses the piston plate, causing the slider on the side of the piston plate to slide inside the groove. This, in turn, moves the piston plate and the pressure rod, which in turn moves the pressure plate to compress the compression spring. The pressure is detected by a pressure sensor at the bottom of the compression spring, and the detected data can be transmitted via wires. When the first trigger switch of the piston plate contacts either the active or driven moving block's second trigger switch, the solenoid valve inside the exhaust pipe opens, allowing exhaust to proceed. When the first and second trigger switches disengage, the solenoid valve inside the exhaust pipe closes, at which point the patient can begin inhalation training.

[0020] 3. This invention uses a rotating block to drive a threaded rod to rotate. Since the threaded rod is threadedly connected to the threaded groove and rotatably connected to the active moving block, the threaded rod drives the active moving block to move. The movement of the active moving block drives the connecting rod to move, which in turn drives the fixed ring to move, thereby causing the driven moving block to move. This changes the positions of the active and driven moving blocks, thereby changing the position of the second trigger switch and thus changing the distance between the first and second trigger switches, thereby adjusting the intensity of the patient's breathing training.

[0021] 4. This invention allows the clamping tube, fixing plate, and breathing tube to be flexibly disassembled and replaced by clamping the clamping tube to the bottom of the corrugated tube. Both ends of the installation tube are provided with second connecting plates, which can be connected to the first connecting plate and the third connecting plate respectively, so that the installation tube can be flexibly replaced. Similarly, the exercise tube can also be flexibly disassembled and replaced, improving the flexibility of the device. Attached Figure Description

[0033] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0034] As attached Figure 1 To be continued Figure 9 As shown:

Each side plate 12 has a placement plate 14 on its opposite side and a pull plate 13 on its far side. A fixing plate 18 is provided between the two placement plates 14. A locking tube 19 is provided at the top of the fixing plate 18 and is locked to the bottom of the corrugated tube 55. A breathing tube 110 is provided at the bottom of the fixing plate 18. The fixing plate 18 has a hole inside, through which the breathing tube 110 communicates with the locking tube 19 and the corrugated tube 55. A locking rod 15 is provided at the top of the placement plate 14 and is locked to the fixing plate 18.

[0037] The filter assembly 7 includes an installation tube 71, with a second connecting plate 72 at both ends of the installation tube 71. The second connecting plate 72 at one end of the installation tube 71 is flange-connected to the first connecting plate 54. Filter screens 73 are provided at both ends inside the installation tube 71. Several filter elements 74 are provided between the two filter screens 73. The filter elements 74 are wrapped with absorbent cotton 75.

[0038] The exercise assembly 8 includes an exercise tube 81. A third connecting plate 82 is located at one end of the exercise tube 81 near the filter assembly 7. The third connecting plate 82 is flange-connected to the second connecting plate 72 of the mounting tube 71. Four sliding grooves 84 are formed on the inner wall of the exercise tube 81. A piston plate 86 is installed inside the exercise tube 81. A slider is located on the side of the piston plate 86, and the piston plate 86 is slidably connected to the sliding grooves 84 via the slider. A pressure rod 88 is located on the side of the piston plate 86 away from the second connecting plate 72, passing through the exercise tube 81. A first trigger switch 87 is located on the side of the slider near the pressure rod 88. An exhaust pipe 85 is located at the bottom of the exercise tube 81, communicating with the interior of the exercise tube 81. A solenoid valve is installed inside the exhaust pipe 85. A fixing ring 89 is provided inside the tube 81. The fixing ring 89 is sleeved on the surface of the pressure rod 88 and is slidably connected to the pressure rod 88. Four connecting rods 813 are provided on the side of the fixing ring 89. One of the connecting rods 813 has an active moving block 810 at its top, and the other three connecting rods 813 have driven moving blocks 811 at their tops. A second trigger switch 812 is provided on the side of the active moving block 810 and the driven moving block 811 near the piston plate 86. Both the active moving block 810 and the driven moving block 811 are slidably connected to the slide groove 84. A threaded rod 814 is rotatably connected to the side of the active moving block 810 away from the second trigger switch 812. A threaded groove 815 is opened on the upper part of the side of the exercise tube 81 away from the third connecting plate 82. A threaded rod 814 passes through a threaded groove 815 and is threadedly connected to it. A rotating block 817 is located at the end of the threaded rod 814 furthest from the active moving block 810. The rotating block 817 is fixedly connected to the threaded rod 814. By rotating the rotating block 817, the threaded rod 814 rotates. Since the threaded rod 814 is threadedly connected to the threaded groove 815 and rotatably connected to the active moving block 810, the threaded rod 814 drives the active moving block 810 to move. The movement of the active moving block 810 drives the connecting rod 813 to move, which in turn drives the fixed ring 89 to move, thereby causing the driven moving block 811 to move. Changing the positions of the active moving block 810 and the driven moving block 811 changes the position of the second trigger switch 812, thereby changing the distance between the first trigger switch 87 and the second trigger switch 812, thus adjusting the intensity of the patient's breathing training. A detection tube 83 is provided on the side of the exercise tube 81 away from the third connecting plate 82. A pressure plate 816 is provided inside the detection tube 83. The pressure plate 816 is fixedly connected to the pressure rod 88 passing through the exercise tube 81. A compression spring 818 is provided inside the detection tube 83. A pressure sensor 819 is fixedly connected to the end of the compression spring 818 away from the pressure plate 816. The compression spring 818 is in contact with the pressure plate 816. A wire 820 is provided on the end of the pressure sensor 819 away from the compression spring 818.

[0039] As can be seen from the above, by connecting the oxygen outlet of the oxygen machine to the oxygen pipeline 53, the device can meet the oxygen supply demand. The patient's exhaled waste gas can be filtered through the breathing plate 9 and the filter screen 4, avoiding insufficient oxygen supply for patients who need oxygen during breathing exercises. When breathing exercises are needed, the oxygen inlet is cut off, and the pull plate 13 is pulled down, causing the pull plate 13 to move the placement plate 14, which in turn moves the fixing plate 18 and the breathing tube 110, and stretches the corrugated tube 55, making the corrugated tube 55 longer. At this time, the patient bites on the breathing tube 110 and exhales. The exhaled gas is filtered through the filter screen 73, filter element 74, and absorbent cotton 75 in the filter assembly 7 to remove water vapor and waste gas exhaled by the patient. The gas expelled compresses the piston plate 86, causing the slider on the side of the piston plate 86 to slide inside the slide groove 84. This causes the piston plate 86 to move the pressure rod 88, which in turn moves the pressure plate 816 to compress the compression spring 818. The pressure is detected by the pressure sensor 819 at the bottom of the compression spring 818, and the detected data can be transmitted through the wire 820. When the first trigger switch 87 of the piston plate 86 contacts either the second trigger switch 812 on the surface of the active moving block 810 or the driven moving block 811, the solenoid valve inside the exhaust pipe 85 opens to exhaust gas. When the first trigger switch 87 is disconnected from the second trigger switch 812, the solenoid valve inside the exhaust pipe 85 closes, and the patient can then perform inhalation training.

[0040] Example 2: This example is basically the same as the previous example, except that a connecting component 3 is provided on the side of the mask body 11. The connecting component 3 includes a connecting pipe 31 and a mounting plate 32. The connecting pipe 31 is located on the side of the mask body 11 and penetrates through the mask body 11. The mounting plate 32 is located inside the connecting pipe 31 and evenly divides the connecting pipe 31 into two parts. A hole is provided in the middle of the mounting plate 32. The connecting component 3 also includes a retention tube inlet 34. The retention tube inlet 34 is located on the side of the mounting plate 32 near the outside of the mask body 11. The retention tube inlet 34 is hollow. The outer surface of 4 is provided with a buckle 39. The connecting component 3 also includes a retention tube outlet 33. The retention tube outlet 33 is located on the side of the mounting plate 32 near the inside of the mask body 11. The retention tube outlet 33 is hollow. The outer surface of the retention tube outlet 33 is provided with a buckle 39. Several second clamps 37 are provided on the side of the retention tube outlet 33 away from the mounting plate 32. A second spring 38 is provided between each second clamp 37 and the inner wall of the connecting tube 31. Several first clamps 35 are provided on the side of the retention tube inlet 34 away from the mounting plate 32. A first spring 36 is provided between each first clamp 35 and the inner wall of the connecting tube 31.

[0041] As can be seen from the above, by connecting the indwelling tube to the indwelling tube inlet 34 and fixing the indwelling tube with the buckle 39 on the surface of the indwelling tube inlet 34, and then pressing the second clamp 37 according to the thickness of the indwelling tube, the second clamp 37 presses the second spring 38, causing the second spring 38 to generate a reaction force, thereby fixing the indwelling tube with the second clamp 37 and preventing the indwelling tube from shifting. At the same time, the indwelling tube is connected to the indwelling tube outlet 33 and fixed with the indwelling tube outlet 33 with the buckle 39 on the surface of the indwelling tube outlet 33. Simultaneously, the first clamp 35 is pressed according to the thickness of the indwelling tube, causing the first clamp 35 to press the first spring 36, causing the first spring 36 to generate a reaction force, thereby fixing the indwelling tube with the first clamp 35. This allows the device to meet the needs of patients with indwelling tubes and improves the practicality of the device.

[0042] Working principle: By snapping the connecting tube 19 to the bottom of the corrugated tube 55, the connecting tube 19, the fixing plate 18, and the breathing tube 110 can be flexibly disassembled and replaced. Both ends of the installation tube 71 are equipped with second connecting plates 72, which can be connected to the first connecting plate 54 and the third connecting plate 82 respectively, allowing the installation tube 71 to be flexibly replaced. Similarly, the exercise tube 81 can also be flexibly disassembled and replaced. Then, by rotating the rotating block 817, the threaded rod 814 is driven to rotate. Since the threaded rod 814 is threadedly connected to the threaded groove 815, and the threaded rod 814 is connected to the active moving block 810... Rotating the connection causes the threaded rod 814 to move the active moving block 810. The movement of the active moving block 810 moves the connecting rod 813, which in turn moves the fixed ring 89, causing the driven moving block 811 to move. This changes the positions of the active and driven moving blocks 810 and 811, thus changing the position of the second trigger switch 812. This, in turn, changes the distance between the first and second trigger switches 87, adjusting the intensity of the patient's breathing training. After adjustment, connecting the oxygen outlet of the oxygen concentrator to the oxygen pipeline 53 allows the device to meet oxygen supply needs, and the patient's exhaled waste gas can be exhaled through the oxygen concentrator. The suction plate 9 and the filter screen 4 filter the air to prevent insufficient oxygen supply to patients who need oxygen during breathing exercises. When breathing exercises are needed, the oxygen inlet is cut off, and the pull plate 13 is pulled down, causing the pull plate 13 to move the placement plate 14, which in turn moves the fixing plate 18 and the breathing tube 110, stretching the corrugated tube 55. At this time, the patient bites on the breathing tube 110 and exhales. The exhaled air passes through the filter screen 73, filter element 74, and absorbent cotton 75 in the filter assembly 7 to filter the water vapor and waste gas exhaled by the patient. The exhaled air compresses the piston plate 86, causing the slider on the side of the piston plate 86 to slide. The piston plate 86 slides inside the groove 84, which in turn causes the piston plate 86 to move the pressure rod 88. The pressure rod 88 then causes the pressure plate 816 to compress the compression spring 818. The pressure is detected by the pressure sensor 819 at the bottom of the compression spring 818. The detected data can be transmitted through the wire 820. When the first trigger switch 87 of the piston plate 86 contacts either the second trigger switch 812 on the surface of the active moving block 810 or the driven moving block 811, the solenoid valve inside the exhaust pipe 85 opens to exhaust air. When the first trigger switch 87 is disconnected from the second trigger switch 812, the solenoid valve inside the exhaust pipe 85 closes. At this time, the patient can perform inhalation training.

[0043] Alternatively, the indwelling tube can be connected to the indwelling tube inlet 34 and fixed using the buckle 39 on the surface of the indwelling tube inlet 34. Then, the second clamp 37 is pressed according to the thickness of the indwelling tube, causing the second clamp 37 to press the second spring 38, which in turn generates a reaction force, thereby fixing the indwelling tube with the second clamp 37 and preventing displacement of the indwelling tube. At the same time, the indwelling tube is connected to the indwelling tube outlet 33 and fixed using the buckle 39 on the surface of the indwelling tube outlet 33. Simultaneously, the first clamp 35 is pressed according to the thickness of the indwelling tube, causing the first clamp 35 to press the first spring 36, which in turn generates a reaction force, thereby fixing the indwelling tube with the first clamp 35. This allows the device to meet the needs of patients with indwelling tubes.
