DETAILED DESCRIPTION

[0016] The following is a clear and complete description of the technical solutions in the embodiments of the present invention in conjunction with the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the protection scope of the present invention.

[0017] At the same time, in order to clearly explain the technical solution of this application, the following is also defined: Figure 1 Shown are upper, lower, front, back, left and right sides.

[0018] like Figures 1 to 3 As shown, the present application provides a respiratory function detection device with better sampling effect, which includes: a shell 11, an air intake component 12, a collection component 13, a control component 14, an air flow pipeline 15 and an oscillation component 16.

[0019] Specifically, the housing 11 is a hollow structure, and is used to accommodate other equipment of the respiratory function detection device.

[0020] The air intake assembly 12 is arranged at the front end of the shell 11, and includes a first air intake pipe 121, a second air intake pipe 122, an isolation net 123 and an air blowing nozzle 124. The first air intake pipe 121 is arranged at the front side of the second air intake pipe 122, connected to the second air intake pipe 122, and forms a gas flow channel inside. The first air intake pipe 121 is at least partially arranged outside the shell 11, and the second air intake pipe 122 is at least partially arranged inside the shell 11. The isolation net 123 is arranged between the first air intake pipe 121 and the second air intake pipe 122, and the gas flow channel is divided into a front part and a rear part. The rear end of the air blowing nozzle 124 is sleeved on the first air intake pipe 121. The bottom of the rear end of the first air intake pipe 121 is provided with a first air outlet 125 along the front-to-back direction, and the first air outlet 125 is connected to the front part of the gas flow channel. The bottom of the front end of the second air intake pipe 122 is provided with a second air outlet 126 along the front-to-back direction, and the second air outlet 126 is connected to the rear part of the gas flow channel.

[0021] The air flow pipeline 15 is disposed in the housing 11 and connected to the second air inlet pipe 122 for transmitting gas.

[0022] The oscillation component 16 is arranged on the upper side of the airflow pipeline 15, connected to the airflow pipeline 15, and includes an oscillation generating component 161 and a connecting pipe 162. The connecting pipe 162 is connected to the airflow pipeline 15. The oscillation generating component 161 is installed on the top of the connecting pipe 162, and is used to make the passing airflow oscillate, thereby providing an external stress, so that when the user blows into the blowing nozzle 124, only normal breathing is required to achieve the airflow required for the test, thereby realizing the lung function test.

[0023] The collection component 13 includes a first collection tube 131 and a second collection tube 132, wherein the first collection tube 131 is connected to the first air outlet 125. The second collection tube 132 is connected to the second air outlet 126. The control component 14 is disposed at the bottom of the housing 11 and is connected to the collection component 13 and the oscillation component 16. The collection component 13 is used to collect gas at the front and rear of the gas flow channel, and the control component 14 is used to perform pressure detection on the collected gas, thereby calculating the airflow volume and airflow change of the person to be tested during breathing, and providing parameters for the lung function test results.

[0024] Through the above settings, the respiratory function detection device can apply stress during the measurement process, reducing the amount of airflow required for measurement. Users only need to breathe steadily to achieve effective measurement of lung function, solving the problem of measurement deviation caused by the inability to generate sufficient airflow in children, the elderly and patients with weak lung function in the prior art. This design not only improves the accuracy of the measurement, but also enhances the applicability of the device to a wider population, further meeting the needs of clinical lung function assessment and disease screening.

[0025] like Figure 3 and Figure 4 As shown, a first annular air guide groove 1211 is provided at the rear side of the first air inlet pipe 121, and the first air guide groove 1211 is gap-matched with the isolation net 123 to form a first air guide pipeline. A plurality of first openings 1212 are provided on the first air guide groove 1211, and the first air guide pipeline is connected to the front part of the gas flow channel through the first openings 1212. The first air outlet 125 is connected to the first air guide pipeline.

[0026] Furthermore, a second annular air guide groove 1221 is provided on the front side of the second air inlet pipe 122, and the second air guide groove 1221 is gap-matched with the isolation net 123 to form a second air guide pipeline. A plurality of second openings are provided on the second air guide groove 1221. The second air guide pipeline is connected to the rear part of the gas flow channel through the second opening. The second air outlet 126 is connected to the second air guide pipeline. Through the above arrangement, two independent collection passages are respectively connected to the front and rear parts of the gas flow channel, which effectively improves the collection sealing and detection accuracy, and avoids the problem of inaccurate collection caused by the displacement or looseness of the air nozzle. At the same time, through the design of the double-layer air guide groove, effective separation and steady flow of the intake air are achieved, the interference of gas turbulence on the collection results is reduced, and the detection accuracy and reliability of the respiratory function detection device are improved.

[0027] An annular first seal 1213 is provided on the outer side of the first air guide groove 1211; an annular second seal 1222 is provided on the outer side of the second air guide groove 1221. The first seal 1213 and the second seal 1222 are respectively interference fit with the isolation net 123. By adding the first seal 1213 and the second seal 1222, the sealing performance of the device is improved, and gas leakage is effectively prevented, thereby further improving the stability and accuracy of pulmonary function testing. In addition, the setting of the seal reduces airflow turbulence and improves the stability of the airflow. Furthermore, the first seal 1213 and the second seal 1222 can be made of silicone material to improve the sealing performance. In addition, the size and shape of the seal can be adjusted according to the specific needs of the device to further optimize the sealing effect and airflow stability.

[0028] like Figure 3 As shown, the rear end of the housing 11 is provided with an air outlet pipe 17, which is connected to the air flow pipeline 15 and the connecting pipe 162. The air outlet pipe 17 is used to balance the air pressure in the air flow pipeline 15, stabilize the gas flow, reduce the occurrence of turbulence, and thus improve the detection accuracy of the equipment. A first filter 171 is provided in the air outlet pipe 17, and the first filter 171 can further stabilize the gas flow and improve the accuracy of the detection.

[0029] A heating element 18 is provided at the bottom of the airflow pipeline 15 near one end of the second air inlet pipe 122. The heating element 18 is connected to the control component 14 and is used to heat the temperature of the gas flow channel and the isolation net 123 to a preset temperature. The preset temperature is 37°C. Through the above arrangement, condensation of water vapor in the air inlet component 12 and the airflow pipeline 15 can be avoided, the dryness of the test gas is ensured, and the service life of the equipment is improved. In addition, the temperature control design of the heating element 18 ensures the adaptability of the respiratory function detection device in different environments.

[0030] The sum of the lengths of the first air outlet 125 and the first collecting tube 131 is substantially the same as the sum of the lengths of the second air outlet 126 and the second collecting tube 132 , so as to reduce the detection error caused by the difference in the length of the airflow path and ensure the accuracy of the detection data.

[0031] A second filter screen 1241 is disposed in the air blowing nozzle 124, and the second filter screen 1241 is used to stabilize the airflow entering the first air inlet pipe 121. The second filter screen 1241 is made of metal material to improve durability and convenience of cleaning.

[0032] A third filter 163 is provided between the oscillation generating element 161 and the connecting tube 162. The third filter 163 is used to stabilize the oscillating airflow transmitted to the connecting tube 162 to prevent the airflow oscillation amplitude from being too large, thereby forming turbulence in the airflow pipeline 15 and affecting the detection results of the respiratory function detection device.

[0033] The oscillation generating element 161 can be configured as a speaker, an oscillation membrane or other structures, with a front end fixedly connected to the front inner wall of the shell 11 and a rear end fixedly connected to the rear inner wall of the shell 11 to improve the stability of the structure.

[0034] like Figure 3 and Figure 5 As shown, the bottom of the rear end of the first air inlet pipe 121 and the bottom of the front end of the second air inlet pipe 122 are provided with a mutually connected clamping portion 127. The front end surface of the housing 11 is provided with a clamping groove 111 corresponding to the clamping portion 127, and the clamping portion 127 is arranged in the clamping groove 111. The cooperation between the clamping portion 127 and the clamping groove 111 can ensure the stability of the connection between the air inlet assembly 12 and the housing 11. The first air outlet 125 and the second air outlet 126 are respectively extended in the clamping portion 127, so that the overall structure of the device is compact and easy to assemble.

[0035] like Figure 6 and Figure 7 As shown, the respiratory function detection device also includes a connecting component 19. The connecting component 19 includes a first connecting member 191 and a second connecting member 192 that are symmetrically arranged on the left and right. The first connecting member 191 is arc-shaped and has a semi-enclosed structure, which is sleeved on the left end of the connection between the first air inlet pipe 121 and the second air inlet pipe 122. The second connecting member 192 is arc-shaped and has a semi-enclosed structure, which is sleeved on the right end of the connection between the first air inlet pipe 121 and the second air inlet pipe 122. Through the above arrangement, the first connecting member 191 and the second connecting member 192 respectively surround the connection between the first air inlet pipe 121 and the second air inlet pipe 122, forming a stable mechanical connection structure, thereby enhancing the overall structural stability of the device. At the same time, the airflow leakage at the connection is effectively reduced, ensuring the detection accuracy.

[0036] Furthermore, first protrusions 1911 are provided on both the front and rear sides of the top of the first connecting member 191. Second protrusions 1921 are provided on both the front and rear sides of the top of the second connecting member 192. A connecting portion 128 is provided on the top of the connection between the first air intake pipe 121 and the second air intake pipe 122. A first groove 1281 corresponding to the first protrusion 191 is provided on the left side of the connecting portion 128, and a second groove 1282 corresponding to the second protrusion 1921 is provided on the right side. The first protrusion 1911 is snap-fitted with the first groove 1281; the second protrusion 1921 is snap-fitted with the second groove 1282, so as to prevent the air intake assembly 12 from shaking, and further enhance the structural stability of the air intake assembly 12.

[0037] Furthermore, the first connecting member 191 has first gripping portions 1912 at both sides of the front and rear of the bottom. The second connecting member 192 has first gripping portions 1922 at both sides of the front and rear of the bottom, so that the user can disassemble and replace the first connecting member 191 and the second connecting member 192 .

[0038] like Figure 1 and Figure 7 As shown, the respiratory function detection device also includes a cover 112, which is annular. The housing 11 surrounding the air intake assembly 12 is provided with a plurality of guide grooves 113 that are rotationally symmetrical about the axis of the air intake assembly 12. The cover 112 is provided with a plurality of guide blocks that can cooperate with the guide grooves 113, so that the cover 112 can be rotated and tightened onto the housing 11. The cover 112 can limit the movement of the air intake assembly 12 in the front-to-back direction, prevent the air intake assembly 12 from loosening and sliding out of the housing 11, and improve the stability of the device structure.
