Description

Technical Field

[0001] This utility model relates to the field of respiratory detection equipment technology, specifically to a lung diffusion detection mechanism. Background Technology

[0002] Breathing tests encompass various types in medical and health monitoring, such as lung diffusion rate (LDR) testing, respiratory flow rate testing, airway resistance testing, and respiratory oxygenation efficiency testing. LDR testing, in particular, measures the ability of gas exchange between the alveoli and blood within the alveolar capillaries through the alveolar-blood-gas barrier. This is achieved by the user inhaling the corresponding test gas and then exhaling it to the testing machine. The LDR device includes an airflow conductor, a test gas supply connected to the airflow conductor, and a testing machine. A breathing nozzle is installed on the airflow conductor, guiding the airflow into the user's mouth for inhalation and then exhaling it to the testing machine. During inhalation, the valve at the connection between the test gas supply and the airflow conductor must open, while the valve at the connection between the testing machine and the airflow conductor must close. Exhalation reverses this process, requiring a rapid valve response. Currently, a common industry practice is to use a telescopic ball valve structure. This involves a telescopic ball at the valve; the ball inflates when the valve is closed and contracts when it is opened. However, this method results in a slow response time, hindering the efficiency and accuracy of LDR testing. Utility Model Content

Detailed Implementation

[0022] 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.

[0023] like Figure 1-5 As shown, this utility model embodiment provides a multifunctional respiratory detection device, including a base 10, a processor and a display mounted on the base 10, and a respiratory detection mechanism mounted on one side of the base 10. The respiratory detection mechanism includes a breathing nozzle 20, an airflow conductor 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 airflow conductor 30. The breathing nozzle 20 is detachably mounted on the respiratory flow detection module 40. The airflow conductor 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 is switched through the valves 32 to realize the respiratory function detection of the corresponding detection modules.

[0024] The base 10 includes a base body 11 and a mounting bracket mounted on the side of the base body 11. A processor, keyboard, and display are mounted on the base body 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.

[0025] Please see Figure 6 , Figure 7In this embodiment, there are four airflow connectors, which are respectively connected around the valve body 31 and 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 splitter head 33. The splitter 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.

[0026] 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.

[0027] Correspondingly, in this embodiment, there are three valves 31, 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 31.

[0028] Furthermore, the airflow conductor 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.

[0029] Furthermore, a sensing actuator (not shown) is installed within the drive unit 34 to issue real-time commands to instruct the operation of the drive unit 34. A breathing state transmission tube 35, which can be a hollow 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 a corresponding drive command 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 employ a tympanic membrane structure, determining whether it is exhalation or inhalation based on the bulging or concavity of the tympanic membrane.

[0030] Furthermore, the air supply unit is connected to the second airflow connector 322 via the guide tube 53 and the guide body 54. Specifically, the guide body 54 is detachably connected to the second airflow connector 322. The air supply unit communicates with the guide body 54 via the guide tube 53.

[0031] 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.

[0032] Further, please refer to Figure 8A 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.

[0033] The respiratory absorption rate detection module includes an oxygen supply cylinder and an oxygen concentration analyzer. The oxygen supply cylinder is filled with oxygen at a preset concentration for respiratory absorption rate detection. The oxygen concentration analyzer analyzes 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 tubing that flows through the oxygen concentration analyzer. During respiratory absorption rate detection, the valves corresponding to the second airflow connector 322 and the fourth airflow connector 324 are kept closed, as are the valves on the detection machine 51; the valve corresponding to the third airflow connector 323 is kept open. Furthermore, the user's inhaled and exhaled gases both pass through the first airflow connector 321, meaning the user's breathing is not interconnected with the outside environment. Thus, the user's inhaled gas is supplied from the oxygen cylinder, and the exhaled gas re-enters the oxygen cylinder, while the oxygen concentration analyzer analyzes the oxygen concentration in real time based on the oxygen in the tubing. Therefore, after a preset breathing cycle, the user's oxygen absorption rate can be analyzed based on the change in oxygen concentration.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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.

[0038] This utility model of a multifunctional respiratory detection device integrates multiple respiratory detection functions. By connecting multiple respiratory detection modules to the same airflow conductor, the structure is simple. The breathing airway is switched by a drive motor driven by a valve inside the airflow conductor. A sensor actuator is set in the drive unit, and a respiratory status transmission tube is connected between the breathing mouth and the sensor actuator. The sensor actuator senses the breathing status of the breathing mouth and accordingly instructs the drive motor of the drive unit to operate. It can perform real-time and precise control of the opening and closing of the valve, which helps to improve the efficiency and accuracy of respiratory function detection.

[0039] Understandably, the lung diffusion detection module 50 can also be separated from the multifunctional respiratory detection device, with the following specific structure:

[0040] A lung diffusion detection mechanism includes an airflow conductor 30, a detection gas supply, a detection unit 51, and a breathing nozzle 20. The airflow conductor 30 includes a valve body 31 and an air inlet connector (i.e., a second airflow connector 322), an air outlet connector (i.e., a third airflow connector 323), and a breathing connector (i.e., a first airflow connector 321) connected to the valve body 31. The valve body 31 is provided with valves 32 that correspond to and cooperate with the air inlet connector and the air outlet connector. The detection gas supply is connected to the air inlet connector, the detection unit 51 is connected to the air outlet connector, and the breathing nozzle 20 is connected to the breathing nozzle. The airflow conductor 30 includes a drive unit 34, which includes a housing and a plurality of drive motors installed in the housing. The housing is fixedly connected to the valve body 31. The shafts of the plurality of drive motors are respectively connected to the corresponding valves 32 to control the corresponding valves 32 to open and close in real time. A sensor actuator is provided in the drive unit 34. The breathing nozzle 20 is connected to the sensor actuator by a breathing state transmission tube 35. The sensor actuator instructs the drive motors of the drive unit 34 to operate accordingly by sensing the breathing state of the breathing nozzle.

[0041] Furthermore, the breathing connector is detachably grounded and connected to a breathing flow detector (i.e., breathing flow detection module 40), and the breathing connector is pluggably grounded and connected to the breathing flow detector.

[0042] Furthermore, the breathing state transmission tube 35 is an air delivery hose.

[0043] Furthermore, a breathing sensor is provided inside the breathing nozzle 20 and is connected to the sensing actuator via a conductive line.

[0044] Furthermore, the breathing sensor employs a tympanic membrane structure.

[0045] 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.
