Description

Technical Field

[0001] The invention relates to the technical field of exercise physiology, in particular to an exercise physiology respiratory vital capacity measuring device. Background Art

[0002] Exercise physiology is the study of how the human body's physiological functions change during exercise or training, encompassing mechanisms such as energy metabolism, cardiovascular and respiratory systems, and muscle physiology. Its core goals are to optimize athletic performance, develop scientific training programs, and assess physiological responses in both healthy and diseased states.

[0003] Among them, the assessment of the respiratory system is generally divided into static vital capacity (VC) and forced vital capacity (FVC). Static vital capacity (VC) refers to the maximum amount of air that the test subject exhales slowly and evenly after a maximum inhalation, which reflects basic lung function, such as lung expansion capacity, chest mobility, diaphragm function, etc.; forced vital capacity (FVC) refers to the maximum amount of air that the test subject exhales quickly and forcefully after a maximum inhalation. Forced vital capacity also includes the expiratory volume in the first second (FEV1), which refers to the total amount of air exhaled in the first second when the test is tested using the spirometry method. The forced vital capacity test is used to evaluate the test subject's airway patency, lung elasticity, respiratory muscle endurance, and aerobic endurance performance. It is extremely suitable for evaluating the test subject's athletic ability in long-distance running, swimming, marathons, etc. The test subject's training intensity and training plan are determined based on the test subject's lung function assessment results, so as to achieve the purpose of scientific training.

[0004] Existing mechanical respiratory vital capacity measurement devices used in exercise physiology research generally consist of a measuring cylinder, a piston moving part, and an air blowpipe. Air is blown into the measuring cylinder through the air blowpipe, causing the piston moving part to rise. The distance the piston moves upward is then used to determine the subject's static vital capacity (VC). However, such vital capacity measurement devices have a limited scope of application and can only measure static vital capacity (VC) using the scale on the measuring cylinder. It is difficult to accurately measure the subject's forced expiratory volume (FVC) and forced expiratory volume in one second (FEV1) simultaneously during a single test, making it difficult to comprehensively assess the subject's lung function.

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

[0018] 1. The present invention adopts a split-structure measuring movable part, and controls the sliding of the movable plate, that is, the switching between two states of the movable plate, so that the first ring body and the second ring body can switch between a synchronous state and a separated state. In the synchronous state, the gas drives the telescopic sleeve, and the first ring body and the second ring body move synchronously; in the separated state, the first ring body is adsorbed on the inner wall of the measuring cylinder by the adsorption part, and the second ring body continues to move upward following the closed end of the telescopic sleeve.

[0019] 2. The adsorption part of the present invention adopts an electromagnet, and a metal strip is arranged on the wall of the measuring tube. The metal strip and the electromagnet in the energized state can be adsorbed, and the response speed of the adsorption action is faster and the adsorption stability is stronger. In addition, the present invention sets the power-on time of the electromagnet, and detects the instantaneous start of the electromagnet controller through the airflow sensor. The controller energizes the electromagnet after the set time, which can more accurately control the separation time point of the first ring body and the second ring body in the exhaled gas period, and accurately measure the tester's exhaled volume in the first second, thereby accurately evaluating the tester's airway patency, lung elasticity, respiratory muscle endurance and aerobic endurance.

[0020] 3. The connecting head of the present invention is provided with a spherical cavity, a spherical channel switching assembly and a rotating shaft. During the air blowing test, a one-way channel with a one-way opening sealing plate, a measuring tube and an air blowing assembly form a passage, and the gas breaks through the sealing plate and enters the measuring tube. After the air blowing is completed, the sealing plate loses the impact of the air flow, is covered due to gravity, and forms a sealing structure with the limiting ring to prevent gas from escaping, leaving time for recording data; when the measurement is completed and the data is recorded, the gas in the telescopic sleeve needs to be released. At this time, the rotating shaft is rotated to connect the two-way channel and the air inlet and the air outlet, so that the gas can be released from the air outlet through the two-way channel. By switching the channel of the connecting head, the measuring equipment can conveniently record the data during the air blowing measurement, and can be quickly reset after the measurement is completed, so that the measuring equipment can be suitable for the work task of multi-person measurement.

[0021] 4. The connecting head, the movable measuring member and the measuring cylinder of the present invention are all detachably connected, and can be easily disassembled and replaced. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] Example

[0042] like Figure 1 As shown, an exercise physiology respiratory vital capacity measuring device includes: a measuring tube 1, a blowing assembly, and a measuring movable member 3 slidably arranged in the measuring tube 1. The tester blows air into the blowing assembly, so that the gas enters the measuring tube 1 from the air inlet end of the measuring tube 1 and drives the measuring movable member 3 to move. Figure 5 As shown, the measuring movable member 3 of this embodiment adopts a split structure, including: a telescopic sleeve 33, a second ring body 32 and a first ring body 31. One end of the telescopic sleeve 33 is open and is connected to the air inlet end of the measuring cylinder 1 through a fixed ring body 34. The gas enters the telescopic sleeve 33 from the air inlet end of the measuring cylinder 1, and the other end of the telescopic sleeve 33 is closed. Figure 2 As shown, driven by gas, the other end moves along the height direction of the measuring cylinder 1 to complete the extension of the telescopic sleeve 33, and the second ring body 32 is connected to the other end of the telescopic sleeve 33; the first ring body 31 is sleeved on the outside of the second ring body 32, as shown in FIG. Figure 6 and Figure 10 As shown, a plurality of movable plates 35 are provided on the annular end surface of the first ring body 31 for sliding along its radial direction. An adsorption member is provided at one end of the movable plate 35 close to the inner wall of the measuring cylinder 1, and the movable plate 35 is configured in two states, such as Figure 6 and Figure 10As shown, one state is: the movable plate 35 is stationary, at this time one end of the movable plate 35 does not exceed the outer ring side of the first ring body 31, and the other end exceeds the inner ring side of the first ring body 31, and the second ring body 32 is restricted from moving upward by the portion exceeding the inner ring of the first ring body 31. The purpose of doing so is that in this state, the gas drives the telescopic sleeve 3 to ensure that the first ring body 31 and the second ring body 32 move synchronously; the other state is: Figure 10 In the state shown, the movable plate 35 slides toward the outer ring side of the first ring body 31, and one end of the movable plate 35 is adsorbed on the inner wall of the measuring cylinder 1 through the adsorption member, and the other end retreats to the inner ring side of the first ring body 31 to release the second ring body 32. At this time, the other end no longer restricts the upward movement of the second ring body 32. At this time, when the gas drives the telescopic sleeve 33 to extend, the first ring body 31 is adsorbed on the inner wall of the measuring cylinder 1 through the adsorption member, and the second ring body 32 continues to move upward following the closed end of the telescopic sleeve 33.

[0043] The first ring body 31 records the exhaled volume in the first second, and the second ring body 32 records the maximum volume of air exhaled quickly and forcefully.

[0044] like Figure 8 As shown, the telescopic sleeve 33 includes: multiple circular rings 331 and multiple membrane bodies 332. The circular rings 331 are hollow circular ring structures made of silicone material, which play a supporting role while reducing the mass. The diameter of each circular ring 331 is smaller than the diameter of the inner ring of the first ring body 31. Each membrane body 332 is a cylindrical structure. A membrane body 332 is connected between every two adjacent circular rings 331. The closed end of the telescopic sleeve 33 is sealed with a sealing membrane.

[0045] In some embodiments, as Figure 10 As shown, the adsorption member is an electromagnet 351, which is embedded in the end surface of the movable plate 35, and the outer side surface of the electromagnet 351 is flush with the end surface of the movable plate 35. The electromagnet 351 is connected to the controller for control. Figure 1 As shown, a metal strip 2 is provided on the wall of the measuring tube 1. The metal strip 2 corresponds to the position of the electromagnet 351, and the metal strip 2 is arranged along the height direction of the measuring tube 1. The controller of the electromagnet 351 can adopt a relay module with a control function. The time 1S is set by the relay, and the controller includes an airflow sensor. The airflow sensor is arranged in the air inlet end of the measuring tube 1 and is connected to the control unit of the relay module. When the airflow is detected, the signal is sent to the relay module. At this time, the relay module energizes the electromagnet 351 after 1S. After the electromagnet 351 is energized, it immediately adsorbs the metal strip 2 and drives the movable plate 35 to move, reaching the second state of the movable plate 35.

[0046] In some embodiments, as Figure 10 and Figure 12As shown, a reset slide 36 is provided between the movable plate 35 and the end surface of the first ring body 31. The reset slide 36 includes: a slide rail 321, a slider 361 and two reset springs 362. The slide rail 321 is opened on the annular end surface of the first ring body 31 along the radial direction of the first ring body 31; the slider 361 slides on the slide rail 321; the two reset springs 362 are respectively provided at both ends of the slider 361, one end is connected to the slider 361, and the other end is connected to the end surface of the slide rail 321. Through the cooperation of the slider 361 and the slide rail 321, the movable plate 35 moves in the set radial direction. After the plate 35 is in the second state and the position data of the second ring body 32 and the first ring body 31 have been recorded, the second ring body 32 compresses the telescopic sleeve 33 by gravity, passes through the first ring body 31, and is located below the first ring body 31. At this time, the circuit of the electromagnet 351 is disconnected, and the movable plate 35 is reset to the first state by the reset spring 362, and the first ring body 31 slides down by gravity. In order to reduce the friction between the inner wall of the measuring cylinder 1 and the second ring body 32 and the first ring body 31, the inner wall of the measuring cylinder 1 and the outer ring surface of the second ring body 32 and the outer ring surface of the first ring body 31 are all smoothed.

[0047] In some embodiments, as Figure 6 As shown, the movable plate 35 is an arc-shaped plate, so that the outer end surface of the movable plate 35 is more closely fitted to the inner wall of the measuring cylinder 1 .

[0048] In some embodiments, as Figure 7 As shown, at least two auxiliary plates 38 are provided on the outer ring surface of the second ring body 32, and one end of the auxiliary plate 38 is slidably connected to the inner wall of the measuring cylinder 1. The auxiliary plate 38 can ensure the sliding stability of the second ring body 32 when it continues to rise, and the outer end surface of the auxiliary plate 38 is also smoothed.

[0049] In some embodiments, as Figure 6 and Figure 7 As shown, a receiving groove 37 is provided on the annular end surface of the first ring body 31. The opening position of the receiving groove 37 corresponds to the position of the auxiliary plate 38 and is used to accommodate the auxiliary plate 38. The end of the receiving groove 37 close to the inner wall of the measuring cylinder 1 is opened so that one end of the auxiliary plate 38 extends out from the opening. Figure 5 As shown, such a design can ensure that the annular end surfaces of the first ring body 31 and the second ring body 32 are flush, so that the movable plate 35 can clamp the second ring body 32 inside the first ring body 31 .

[0050] like Figure 1 As shown, the air inlet end of the measuring cylinder 1 and the air blowing assembly are connected through a connecting head 4, and the air blowing assembly includes a connecting hose and an air blowing cover. This is the prior art and will not be described in detail. Figure 13 、 Figure 14 and Figure 15As shown, the connecting head 4 includes: a spherical cavity 41, a spherical channel switching component 6 and a rotating shaft 5. The spherical cavity 41 is opened inside the connecting head 4, and a rubber layer is laid on the cavity wall of the spherical cavity 41. The rubber layer has a certain elasticity. Through the elasticity of the rubber layer, it is squeezed to the channel opening to play the role of sealing the channel, as shown in FIG. Figure 13 As shown, the spherical cavity 41 is provided with an air inlet 43 and an air outlet 42, and the connecting head 4 is provided with a rotating shaft limiting groove 44, and the rotating shaft limiting groove 44 is connected to the spherical cavity 41; Figure 14 and Figure 15 As shown, the spherical channel switching assembly 6 is a spherical structure, which is rotatably arranged in the spherical cavity 41. Two channels are opened on the spherical channel switching assembly 6, namely the one-way channel 61 and the two-way channel 62; the rotating shaft 5 is rotatably sleeved in the rotating shaft limiting groove 44, and one end is connected to the spherical channel switching assembly 6, which is used to rotate the spherical channel switching assembly 6 so that the air inlet end of the measuring cylinder 1 switches between the one-way channel 61 and the two-way channel 62. The one-way channel 61 is a tubular channel, and a sealing plate 611 and a limiting ring body 612 are provided inside. The limiting ring body 612 is sleeved in the one-way channel 61, and the sealing plate 611 is a circular sealing plate. The sealing plate 611 is located on one side of the limiting ring body 612, and its diameter is larger than the diameter of the inner ring of the limiting ring body 612. One end of the sealing plate 611 is hinged to the channel wall of the one-way channel 61. When the one-way channel 61 is connected to the air inlet end of the measuring tube 1, it is used for air blowing test. The one-way channel 61 has a one-way opening sealing plate 611. The gas entering the measuring tube 1 from the blowing assembly rushes open the sealing plate 611. When the blowing is completed, the sealing plate 611 loses the impact of the airflow and is covered by gravity, and forms a sealing structure with the limiting ring body 612. In order to make the sealing plate 611 close quickly, a torsion spring structure can also be used to achieve rapid reset, but the torsion force of the torsion spring should not be too large to prevent the airflow from rushing open the sealing plate 611. When the measurement is completed and the data is recorded, the gas in the telescopic sleeve 33 needs to be released. At this time, the rotating shaft 5 is rotated to connect the two-way channel 61 and the air inlet 42 and the air outlet 43, so that the gas can be released from the air outlet 43 through the two-way channel 61.

[0051] In some implementations, such as Figure 9 and Figure 11 As shown, in order to facilitate the disassembly of the connecting head 4 when it is damaged or to check the air tightness, the connecting head 4 and the air inlet end of the measuring cylinder 1 are connected by threads, and in order to replace and maintain the measuring moving part 3, the measuring moving part 3 is conveniently disassembled, as shown in FIG. Figure 9 As shown, a clamping hole 12 is provided on the inner wall of the measuring cylinder 1 near the bottom. Figure 11As shown, a frustum is provided at the bottom of the fixed ring body 34, and the frustum and the fixed ring body 34 are arranged concentrically, and the diameter of the frustum is smaller than the diameter of the fixed ring body 34. A fixing pin assembly 39 is provided on the outer circumference of the frustum, and the fixing pin assembly 39 corresponds to the position of the clamping hole 12, including: a screw 391 and a threaded sleeve 392, one end of the screw 391 is connected to the frustum; the threaded sleeve 392 is sleeved on the outside of the screw 391 and is threadedly connected to the screw 391, and the diameter of the threaded sleeve 392 is smaller than the diameter of the clamping hole 12.

[0052] During a forced vital capacity test, Figure 1 As shown, the blowing assembly, the connecting head 4 and the measuring cylinder 1 are assembled, and the measuring movable part 3 is in the retracted state. At this time, the tester tries to inhale as much as possible and blows the gas into the measuring cylinder 1 with force and speed. At this time, the air flow sensor detects the air flow and transmits the signal to the relay module. The relay module will energize the electromagnet 351 after one second. Figure 2 As shown, the gas driven telescopic sleeve 33 begins to extend, as shown in FIG. Figure 3 As shown, after one second, the electromagnet 351 is energized to adsorb and fix the movable plate 35 on the inner wall of the measuring tube 1. At this time, the position of the first ring body 31 at the scale line 11 on the measuring tube 1 is recorded, which is the tester's exhaled volume in the first second; the gas continues to drive the telescopic sleeve 33 to extend, so that the second ring body 32 continues to rise, and the highest position to which the second ring body 32 slides is recorded, which is the maximum amount of air exhaled by the tester with force and speed.

[0053] The measuring device of this embodiment can also measure static vital capacity. It only needs to disconnect the circuit of the electromagnet 351 at all times and measure it using a conventional static vital capacity measurement method.

[0054] The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the scope of protection of the present invention.
