DETAILED DESCRIPTION

[0022] The specific implementation of the present application is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present application, and is not used to limit the present application.

[0023] like Figure 1-5 As shown, an embodiment of the present invention provides a multifunctional breathing detection device, including a base 10, a processor and a display installed on the base 10, and a breathing detection mechanism installed on one side of the base 10, the breathing detection mechanism includes a breathing nozzle 20, an airflow conductor 30, and a breathing flow detection module 40, a lung diffusion detection module 50, a respiratory resistance detection module 60, and a respiratory absorption rate detection module respectively connected to the airflow conductor 30, the breathing nozzle 20 is detachably mounted on the breathing flow detection module 40, the airflow conductor 30 includes a valve body 31 and a plurality of airflow connectors connected to the valve body 31, and a valve 32 for switching the airflow direction corresponding to the plurality of airflow connectors is arranged in the valve body 31, the lung diffusion detection module 50 includes an airflow supply body (not shown) and a detection machine 51, the breathing flow detection module 40, the airflow supply body, the detection machine 51, the respiratory resistance detection module 60, and the respiratory absorption rate detection module are respectively connected to the airflow connector on the valve body 31, and the airway channel is switched by the valve 32 to realize the respiratory function detection of the corresponding detection module.

[0024] The base 10 includes a base body 11 and a mounting bracket mounted on the side of the base body 11. A processor, a keyboard and a display are mounted on the base body 11. The respiratory flow detection module 40, the detection machine 51, the respiratory resistance detection module 60 and the respiratory absorption rate detection module are all electrically connected to the processor. The data detected by the detection module 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 seat structure 13 is installed at the end of the rotating arm 12 for mounting the respiratory detection mechanism.

[0025] In this embodiment, there are four airflow connectors, which are respectively connected to the four sides of the valve body 31, which 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; wherein, 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 respiratory 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 the airflow supply body, the third airflow connector 323 is connected to a diverter 33, the diverter 33 has two branch pipes 331, which are used to be connected to the detection machine 51 and the respiratory absorption rate detection module respectively, and the fourth airflow connector 324 is connected to the rear end of the valve body 31, and is used to connect the respiratory resistance detection module 60.

[0026] Preferably, the breathing nozzle 20 is connected to the breathing flow detection module 40, and the breathing flow detection module 40 is connected to the first airflow connector 321. In this way, each breath will pass through the breathing flow detection module 40. When the breathing flow detection module 40 is turned on, the flow detection of each breath can be performed in real time. When the breathing flow detection is not needed, the breathing flow detection module 40 can be turned off. When exhaling, the airflow enters the valve body 31 from the breathing nozzle 20 through the flow detection module 40, and when inhaling, the airflow enters the breathing nozzle 20 from the valve body 31 through the flow detection module 40.

[0027] Correspondingly, in the present embodiment, there are three valves 31, which are respectively installed in the valve body 31 at the connection positions corresponding to the second airflow connector 322, the third airflow connector 323 and the fourth airflow connector 324 and 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, and there is no need to set the valve 31.

[0028] For further information, see Figure 6 , Figure 7The air flow conductor 30 includes a driving member 34, which is installed on the valve body 31 and is used to drive the corresponding valve 32 in the valve body 31 to move. In this embodiment, the driving member 34 includes a housing and three driving motors (not shown) installed in the housing. The housing is fixedly connected to the valve body 31, and the rotating shafts of the three driving motors are respectively connected to the corresponding valves 32 to control the corresponding valves 32 to open and close instantly.

[0029] Furthermore, a sensing actuator (not shown) is provided in the driving member 34 to issue real-time instructions to indicate the action of the driving member 34; the breathing nozzle 20 and the sensing actuator are connected to a breathing state transmission tube 35, which can be a hollow plastic tube. The air pressure of exhalation or inhalation in the breathing nozzle 20 is transmitted to the sensing actuator through the airflow pressure of the breathing state transmission tube 35, so that the sensing actuator can know whether the airflow in the breathing nozzle 20 is exhaled or inhaled, and issue a corresponding driving instruction to the driving member 34. It can be understood that a breathing sensor can also be provided in the breathing nozzle 20, and connected to the sensing actuator through a conductive line. For example, the breathing sensor can adopt a tympanic membrane structure to judge exhalation or inhalation according to the bulging or depression of the tympanic membrane.

[0030] Furthermore, the airflow supply body is connected to the second airflow connector 322 through the conducting tube 53 and the conducting body 54 . Specifically, the conducting body 54 is detachably connected to the second airflow connector 322 . The airflow supply body is communicated with the conducting body 54 through the conducting tube 53 .

[0031] When performing lung diffusion detection, the valve corresponding to the fourth airflow connector 324 is always kept closed, and the branch pipe 331 of the respiratory absorption rate detection module is closed; when the user inhales, the valve corresponding to the second airflow connector 322 is opened, and the third airflow connector 323 is closed at the same time, and a special detection gas is supplied through the airflow supply body, and the gas passes through the second airflow connector 322 and then passes through the first airflow connector 321 to be inhaled into the user's lungs. When exhaling, the valve corresponding to the third airflow connector 323 is opened, and the valve corresponding to the second airflow connector 322 is closed, so that the exhaled gas passes through the third airflow connector 323 and enters the detection machine 51, and the gas is detected by the detection machine 51 and discharged to the outside, and the detection machine 51 detects the exhaled gas. In this way, after multiple breaths, the driving member 34 immediately switches the valves of the second airflow connector 322 and the third airflow connector 323, so that each inhaled gas passes through the detection machine 51 after exhalation, thereby realizing lung diffusion detection of the user.

[0032] When performing respiratory resistance detection, the valve corresponding to the fourth airflow connector 324 is kept open, and the valves corresponding to the second airflow connector 322 and the third airflow connector 323 are closed. In this way, each time the gas exhaled by the user passes through the fourth airflow connector 324 and is discharged through the respiratory resistance detection module 60, thus realizing the respiratory resistance detection of the user.

[0033] The respiratory absorption rate detection module includes an oxygen supply bottle and an oxygen concentration analyzer. The oxygen supply bottle is filled with oxygen of a preset concentration for respiratory absorption rate detection. The oxygen concentration analyzer is used to analyze the concentration of oxygen and is electrically connected to the processor. The oxygen supply bottle is connected to the branch pipe 331 of the shunt head 33 through the trachea and flows through the oxygen concentration analyzer. When performing the respiratory absorption rate detection, the valves corresponding to the second air flow connector 322 and the fourth air flow connector 324 are always closed, and the detection machine 51 is closed; the valve corresponding to the third air flow connector 323 is always opened, and the inhaled and exhaled gases of the user are all through the first air flow connector 321, that is, the user's breathing is not intercommunication with the outside world. In this way, the gas inhaled by the user is supplied from the oxygen bottle, and the exhaled gas enters the oxygen bottle again, and the oxygen concentration analyzer can analyze the concentration of oxygen in real time according to the oxygen in the pipeline. Therefore, after the preset time of such a respiratory cycle, the absorption rate of the user's oxygen can be analyzed according to the change of oxygen concentration.

[0034] The specific structure of the multifunctional breathing detection device is further explained below.

[0035] Furthermore, the fixed seat structure 13 includes a fixed connection block 131 and a fixed rod 132. The fixed connection block 131 is installed at the end of the rotating arm 12. One end of the fixed rod 132 is fixed to the fixed connection block 131, and the other end is fixed to the housing of the driving member 34. In this way, the fixed rod 132 can support the airflow conductor 30 and the respiratory flow detection module 40, lung diffusion detection module 50, respiratory resistance detection module 60, and respiratory absorption rate detection module connected to the airflow conductor 30 in the air, and move in the air through the rotation of the rotating arm 12. Preferably, the fixed rod 132 can be a stainless steel rod.

[0036] For further information, see Figure 8The fixing rod 132 is provided with a blocking structure, which is located below the first airflow connector 321, to prevent the respiratory flow detection module 40 from being disengaged from the first airflow connector 321 and to stably support the respiratory flow detection module 40. The blocking structure includes a support block 14, one end of which can be tightly sleeved on the fixing rod 132, and can be tightly fixed on the fixing rod 132 after being screwed, and can slide along the fixing rod 132 after the screw is released. The support block 14 is formed with a notch 141 for the lower end of the suction flow detection module 40 to be swung into the notch 141 for clamping. In this way, the frequent use of the breathing nozzle 20, such as replacement of the breathing nozzle 20, and frequent plugging and unplugging of the breathing nozzle 20 and the breathing flow detection module 40, can prevent the breathing flow detection module 40 from being disengaged from the first airflow connector 321. By setting a clamping structure, it can be ensured that the suction flow detection module 40 is stably connected to the first airflow connector 321, and the support block 14 has a certain supporting effect on the breathing flow detection module 40. When it is necessary to adjust the angle of the breathing flow detection module 40 or replace the breathing flow detection module 40, it is only necessary to swing the breathing flow detection module 40 out of the notch 141.

[0037] Preferably, the oxygen concentration analyzer is installed in the detection machine 51, and a lung diffusion detection air inlet connector 511 and an absorbance detection air inlet connector 512 are provided on the outer peripheral wall of the detection machine 51, corresponding to the two branch pipes 331 connected to the diverter head 33, wherein the lung diffusion detection air inlet connector 511 is connected to the lung diffusion detection pipeline in the detection machine 51, and the absorbance detection air inlet connector 512 is connected to the oxygen concentration analyzer in the detection machine 51, and the oxygen concentration analyzer is connected to the oxygen supply cylinder.

[0038] Furthermore, a hanging structure is provided at the bottom of the detector 51 for hanging the oxygen supply cylinder. An air guide hole 513 is provided at the bottom of the detector 51, and the air guide hole 513 is connected to the oxygen concentration analyzer, and the air guide hole 513 is used to connect the oxygen supply cylinder.

[0039] See also Fig. 9 , Fig.10The hanging structure includes a hanging member 521, a pressing plate 522 and a lock 523. The hanging member 521 includes a drawer plate 5211 and a sealing body 5212 integrally connected to the bottom surface of the drawer plate 5211. The drawer plate 5211 can be translated against the bottom surface of the detection machine 51, and a handle hole is provided at one end thereof for holding and pulling out the drawer plate 5211. The sealing body 5212 is used to seal the mouth of the oxygen supply bottle, and the oxygen supply bottle can be suspended on the bottom surface of the drawer plate 5211. It can be understood that the sealing body 5212 is provided with an air guide channel, and the air guide hole runs through the top surface of the drawer plate 5211. The pressing plate 522 is used to press the drawer plate 5211 against the bottom surface of the detection machine 51. A U-shaped slot 5221 is provided on the pressing plate 522 for the sealing body 5212 to be mounted thereon, and for the sealing body 5212 to slide in or out laterally. A through hole 5222 is provided on the pressing plate 522 for the rod end of the lock buckle 523 to pass through and connect to the bottom surface of the detection machine 51. The lock buckle 523 adopts a common elastic buckle on the market, and those skilled in the art can directly purchase it from the market according to the shape of the attached figure. The specific structure is not described in this application. The rod end of the lock buckle 523 passes upward and is connected to the bottom surface of the detection machine 51. By swinging the lock buckle handle, the pressing plate 522 can be pressed against the withdrawal plate 5211, or the pressing plate 522 can be released from the pressure, so that the withdrawal plate 5211 can be withdrawn for replacement of the oxygen supply cylinder. It can be understood that when the pressing plate 522 presses the drawer plate 5211 to the bottom surface of the detection machine 51 , the air guide channel provided in the sealing body 5212 is aligned with the air guide hole 513 correspondingly opened on the bottom surface of the detection machine 51 .

[0040] Furthermore, the multifunctional breathing detection device also includes an atomization absorption device 90, so that the user can inhale volatile drugs. Figure 1-Figure 2 and Fig.11 The atomization absorption device 90 includes an air intake box 91, a dosing tube 92, and a diffusion box 93. An air outlet pipe 911 is provided at one end of the air intake box 91, and an air inlet pipe is provided at the other end. The air outlet pipe 911 is used to connect an air intake nozzle 20 for inhalation; the dosing tube 92 and the diffusion box 93 are fixedly connected to both sides of the air intake box 91, and the diffusion box 93 is connected to the cavity of the air intake box 91. The diffusion box 93 is connected to the dosing tube 92 through an air guide tube. In this way, when volatile tablets are placed in the dosing tube 92, the medicine will evaporate through the air guide tube and enter the diffusion box 93. A fan is provided in the diffusion box 93 to diffuse the medicine and fan it into the air intake box 91. The user inhales air into the air intake box 91 through the air intake nozzle 20 connected to the air outlet pipe 91, so that the medicinal gas can be inhaled smoothly. It can be understood that the air inlet pipe at the other end of the air inlet box 91 can assist in the intake of air. At the same time, a filter or a one-way valve is provided in the air inlet pipe to filter the outside air into the air inlet box 91 and then into the air outlet pipe 911, and can more completely prevent the medicinal gas from flowing out of the air inlet pipe.

[0041] Furthermore, the atomizing absorption device 90 includes a connecting rod 94, one end of which is connected to the rotating arm 12, and the other end is connected to the diffusion box 93, which can form a support for the entire suction device formed by the diffusion box 93, the suction box 91 and the dosing tube 92, and the rotating arm 12 swings to drive the entire suction device to move.

[0042] The multifunctional respiratory detection equipment can be used for respiratory flow detection, lung diffusion detection, respiratory tract resistance detection, respiratory absorption rate detection and atomization absorption, and integrates multiple respiratory detection or usage functions. Among them, respiratory flow detection, lung diffusion detection, respiratory tract resistance detection, and respiratory absorption rate detection share an airflow conductor 30. The valve body 31 in the airflow conductor 30 is combined with the drive member to control the airflow path, which can greatly simplify the structure. In particular, by arranging a respiratory state transmission tube 35 between the respiratory nozzle 20 and the sensing actuator of the drive member 34, the respiratory state can be transmitted to the sensing actuator in real time, thereby instantly indicating the action of the drive member 34. For example, when performing lung diffusion detection, the valve corresponding to the fourth airflow connector 324 is always closed. When inhaling special detection gas, the respiratory state transmission tube 35 transmits the inhalation signal, the valve corresponding to the second airflow connector 322 opens, and the valve corresponding to the third airflow connector 323 closes; when exhaling after inhalation, the respiratory state transmission tube 35 transmits the exhalation signal, the sensing actuator instructs the driving member 34 to move, the valve corresponding to the second airflow connector 322 closes, and the valve corresponding to the third airflow connector 323 opens. In this way, the exhaled airflow enters the detection machine 51. Through the above-mentioned structural design, the signal control is fast and accurate.

[0043] The oxygen concentration analyzer of the respiratory absorption rate detection module in the present invention is installed in the detection machine 51, and a pluggable hanging structure is set on the bottom surface of the detection machine 51 to hang the oxygen supply bottle, and a lung diffusion detection air inlet connector 511 and an absorption rate detection air inlet connector 512 are set on the detection machine 51, and are respectively connected to the two branch pipes 331 of the diverter head 33 connected to the third airflow connector 323, which simplifies the overall structure and is easy to use.

[0044] In summary, the multifunctional breathing detection equipment of the present invention integrates multiple breathing detection functions. It has a simple structure by connecting multiple breathing detection modules to the same airflow conductor, and the breathing air circuit is switched by the valve in the airflow conductor. The electrical sensing is used to instantly drive the valve switching, and the switching of the breathing air circuit is achieved. Rapid and high-precision control is achieved, and the breathing absorption rate detection module is installed on the detection machine of the lung diffusion detection module, and the same airflow connector is used together, which further optimizes the overall structural layout of the multifunctional breathing detection equipment. The entire equipment only needs to use one breathing nozzle to perform multiple function detections, and is easy to use.

[0045] The above-described embodiments only express the implementation methods of the present invention, but they cannot be understood as limiting the scope of the patent of the present invention. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
