Description

Technical Field

[0001] This utility model relates to the field of respiratory detection equipment technology, specifically to a multifunctional respiratory detection device and airway connection structure. Background Technology

[0002] Breathing tests encompass various types in medical and health monitoring, such as lung diffusion rate testing, respiratory flow rate testing, airway resistance testing, and respiratory oxygenation efficiency testing. Lung diffusion rate testing measures the ability of gas exchange between the alveoli and blood in the alveolar capillaries across the alveolar blood-gas barrier. This is achieved by the subject inhaling a specific test gas and then exhaling it through a testing machine. Airway resistance testing measures the patency of breathing by observing the passage of exhaled air through a respiratory tract detector. Currently, the most common method for testing various respiratory functions is to use separate instruments for each function. In addition to the testing, the industry has also developed multi-functional respiratory testing machines that integrate multiple respiratory testing functions. By integrating multiple respiratory function tests into one unit, the overall structure can be simplified and it is easy to use. For multi-function respiratory testing devices, a gas path connector that can realize multiple airflow channels is mainly required. By controlling the airflow direction of the gas path connector, the corresponding respiratory testing function can be realized. Currently, the most common gas path connector in the industry is the ball valve structure for controlling the gas path. The gas path is opened or blocked by the expansion and contraction of the ball valve. However, the expansion or contraction of the ball valve takes a long time, resulting in low control accuracy.

Detailed Implementation

[0026] The specific embodiments of this application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit this application.

[0027] like Figure 1-5As shown, this utility model embodiment provides a multifunctional respiratory detection device, including a main unit 10 and a respiratory detection mechanism installed on one side of the main unit 10. The respiratory detection mechanism includes a breathing nozzle 20, an airway connector 30, and a respiratory flow detection module 40, a lung diffusion detection module 50, an airway resistance detection module 60, and a respiratory absorption rate detection module, which are respectively connected to the airway connector 30. The breathing nozzle 20 is detachably installed on the respiratory flow detection module 40. The airway connector 30 includes a valve body 31 and several airflow connectors connected to the valve body 31. The valve body 31 is provided with valves 32 that correspond to the several airflow connectors for switching the airflow direction. The lung diffusion detection module 50 includes an airflow supply (not shown) and a detection unit 51. The respiratory flow detection module 40, the airflow supply, the detection unit 51, the airway resistance detection module 60, and the respiratory absorption rate detection module are respectively connected to the airflow connectors on the valve body 31. The airway channels are switched through the valves 32 to realize the respiratory function detection of the corresponding detection modules.

[0028] The main unit 10 includes a base 11 and a mounting bracket mounted on the side of the base 11. A processor, keyboard, and display are mounted on the base 11. The respiratory flow detection module 40, the detection unit 51, the airway resistance detection module 60, and the respiratory absorption rate detection module are all electrically connected to the processor. The data detected by the detection modules is processed by the processor and displayed on the display. The mounting bracket includes a support rod and a rotating arm 12 rotatably connected to the top of the support rod. A fixed base structure 13 is mounted at the end of the rotating arm 12 for mounting the respiratory detection mechanism.

[0029] Please see Figure 6 , Figure 7 In this embodiment, there are four airflow connectors, which are respectively connected to the four directions of the outer peripheral surface of the valve body 31. They can be regarded as the first airflow connector 321, the second airflow connector 322, the third airflow connector 323, and the fourth airflow connector 324. The first airflow connector 321 is connected to the front end of the valve body 31 and is used to connect the breathing nozzle 20 or the breathing flow detection module 40. The second airflow connector 322 and the third airflow connector 323 are respectively connected to the two sides of the valve body 31. The second airflow connector 322 is used to connect to the airflow supply body. The third airflow connector 323 is connected to a diverter head 33. The diverter head 33 has two branch pipes 331, which are used to connect to the detector 51 and the breathing absorption rate detection module respectively. The fourth airflow connector 324 is connected to the rear end of the valve body 31 and is used to connect to the respiratory resistance detection module 60.

[0030] Preferably, the mouthpiece 20 is connected to the breathing flow detection module 40, which is connected to the first airflow connector 321. Thus, each breath passes through the breathing flow detection module 40. Turning on the breathing flow detection module 40 allows for real-time flow detection of each breath. When breathing flow detection is not required, the breathing flow detection module 40 can be turned off. During exhalation, airflow passes from the mouthpiece 20 through the flow detection module 40 into the valve body 31; during inhalation, airflow passes from the valve body 31 through the flow detection module 40 into the mouthpiece 20.

[0031] Understandably, the breathing nozzle 20 can also be directly connected to the first airflow connector 321.

[0032] In this embodiment, there are three valves 32, which are respectively installed in the valve body 31 at the connection points of the second airflow connector 322, the third airflow connector 323 and the fourth airflow connector 324 with the valve body 31. It can be understood that the first airflow connector 321 is connected to the breathing nozzle 20 and needs to be kept in a normally open state, so there is no need to set valves 32.

[0033] Furthermore, the pneumatic connection 30 includes a drive element 34, which is mounted on the valve body 31 and used to drive the corresponding valve 32 inside the valve body 31 to operate. In this embodiment, the drive element 34 includes a housing and three drive motors (not shown) mounted inside the housing. The housing is fixedly connected to the valve body 31, and the shafts of the three drive motors are respectively connected to the corresponding valves 32 to control the immediate opening and closing of the corresponding valves 32.

[0034] Furthermore, a sensing actuator (not shown) is installed within the drive unit 34 to issue real-time commands instructing the operation of the drive unit 34. A breathing state transmission tube 35, which can be a soft plastic tube, connects the mouthpiece 20 to the sensing actuator. The air pressure of inhalation or exhalation within the mouthpiece 20 is transmitted to the sensing actuator through the airflow pressure in the breathing state transmission tube 35. Thus, the sensing actuator can determine whether the airflow within the mouthpiece 20 is exhalation or inhalation and issue corresponding drive commands to the drive unit 34. Understandably, a breathing sensor can also be installed within the mouthpiece 20 and connected to the sensing actuator via a conductive line. For example, the breathing sensor can adopt a diaphragm structure, determining whether it is exhalation or inhalation based on the bulging or depression of the diaphragm.

[0035] Furthermore, the air supply body is connected to the second air supply connector 322 via the guide tube 53 and the guide body 54. Specifically, the guide body 54 is detachably connected to the second air supply connector 322. The air supply body is connected to the guide body 54 via the guide tube 53.

[0036] Furthermore, the fixed base structure 13 includes a fixed connecting block 131 and a fixed connecting rod 132. The fixed connecting block 131 is installed at the end of the rotating arm 12, and one end of the fixed connecting rod 132 is fixed to the fixed connecting block 131, while the other end is fixed to the housing of the drive component 34. Thus, the fixed connecting rod 132 can support the airflow conductor 30 and the respiratory flow detection module 40, lung diffusion detection module 50, airway resistance detection module 60, and respiratory absorption rate detection module connected to the airflow conductor 30 in the air, and move them in the air driven by the rotation of the rotating arm 12. Preferably, the fixed connecting rod 132 can be made of stainless steel.

[0037] Further, please refer to Figure 8 A locking structure is installed on the fixing rod 132, located below the first airflow connector 321, to prevent the respiratory flow detection module 40 from detaching from the first airflow connector 321 and to stably support the respiratory flow detection module 40. The locking structure includes a support block 14, one end of which is clamped onto the fixing rod 132. After being locked with screws, it is clamped and fixed on the fixing rod 132. After the screws are released, it can slide along the fixing rod 132. The support block 14 has a slot 141 for the lower end of the inhalation flow detection module 40 to be inserted into and held in place. This prevents the inhalation flow detection module 40 from detaching from the first airflow connector 321 during frequent use of the breathing nozzle 20, such as when it is replaced or frequently plugged and unplugged. The locking structure ensures that the inhalation flow detection module 40 is stably connected to the first airflow connector 321, and the support block 14 provides support for the inhalation flow detection module 40. When it is necessary to adjust the angle of the inhalation flow detection module 40 or replace it, the module simply needs to be moved out of the slot 141.

[0038] Understandably, the locking structure can also be mounted on the housing of the drive component 34.

[0039] The respiratory absorption rate detection module includes an oxygen supply cylinder and an oxygen concentration analyzer. The oxygen supply cylinder is filled with oxygen of a preset concentration for respiratory absorption rate detection. The oxygen concentration analyzer is used to analyze the oxygen concentration and is electrically connected to the processor. The oxygen supply cylinder is connected to the branch pipe 331 of the splitter head 33 via a gas tube and the oxygen concentration analyzer.

[0040] Preferably, the oxygen concentration analyzer is installed inside the detector 51. The outer peripheral wall of the detector 51 is provided with a lung diffusion detection inlet connector 511 and an absorption rate detection inlet connector 512, which are connected to the two branch pipes 331 of the shunt head 33. The lung diffusion detection inlet connector 511 is connected to the lung diffusion detection pipeline inside the detector 51, and the absorption rate detection inlet connector 512 is connected to the oxygen concentration analyzer inside the detector 51. The oxygen concentration analyzer is connected to the oxygen supply cylinder.

[0041] Furthermore, the bottom of the testing machine 51 is equipped with a suspension structure for suspending the oxygen supply cylinder. The bottom surface of the testing machine 51 has a gas guide hole 513, which is connected to the oxygen concentration analyzer and is used to guide the oxygen supply cylinder.

[0042] During lung diffusion detection, the valve corresponding to the fourth airflow connector 324 is kept closed, as is the branch pipe 331 connecting to the respiratory absorption rate detection module. When the user inhales, the valve corresponding to the second airflow connector 322 opens, while the third airflow connector 323 closes. Dedicated detection gas is supplied through the airflow supply unit. The gas passes through the second airflow connector 322 and then through the first airflow connector 321, where it is inhaled into the user's lungs. When exhaling, the valve corresponding to the third airflow connector 323 opens, and the valve corresponding to the second airflow connector 322 closes, allowing the exhaled gas to enter the detector 51 through the third airflow connector 323. The gas is detected by the detector 51 and discharged to the outside. The detector 51 detects the exhaled gas. After multiple breaths, the drive unit 34 immediately switches the valves of the second airflow connector 322 and the third airflow connector 323, ensuring that each inhaled gas passes through the detector 51 after exhalation, thus enabling lung diffusion detection of the user.

[0043] When performing airway resistance detection, the valve corresponding to the fourth airflow connector 324 is kept open, while the valves corresponding to the second airflow connector 322 and the third airflow connector 323 are closed. In this way, the air exhaled by the user passes through the fourth airflow connector 324 and is discharged through the airway resistance detection module 60, thus realizing the detection of airway resistance for the user.

[0044] During respiratory absorption rate testing, the valves corresponding to the second airflow connector 322 and the fourth airflow connector 324 are kept closed, as are the valves connected to the testing machine 51; the valve corresponding to the third airflow connector 323 is kept open, and the user's inhaled and exhaled air both pass through the first airflow connector 321, meaning the user's breathing is not interconnected with the outside environment. In this way, the user's inhaled air is supplied from the oxygen cylinder, and the exhaled air re-enters the oxygen cylinder, while the oxygen concentration analyzer can analyze the oxygen concentration in real time based on the oxygen in the pipeline. Therefore, after a preset breathing cycle, the user's oxygen absorption rate can be analyzed based on the change in oxygen concentration.

[0045] This utility model multifunctional respiratory detection device integrates multiple respiratory detection functions. By connecting multiple respiratory detection modules to the same airway connector, the structure is simple. A valve is set at the connection between the airflow connector and the valve body. The valve is controlled to close by a corresponding drive motor. The drive motor has a fast response speed. The respiratory airway is switched by driving the valve with the drive motor. Furthermore, the valve switching is driven in real time by electrical sensing, which realizes fast and highly accurate control of the switching of the respiratory airway.

[0046] The embodiments described above merely illustrate the implementation of this utility model, and should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
