[0023] Embodiment 1

[0024] As Figures 1 to 2 shown, this embodiment provides a structure for simulating the human breathing frequency, including a simulated lung (not shown in the figure), a three-way connector 100, an inhalation power component 200, an exhalation power component 300, a first selection valve 400, and a second selection valve 500;

[0025] The three-way connector 100 includes a first connection port, a second connection port, and a third connection port. The first connection port is connected to the simulated lung, the second connection port is connected to the inhalation power component 200, and the third connection port is connected to the exhalation power component 300;

[0026] The first selection valve 400 is arranged between the second connection port and the inhalation power component 200, and the second selection valve 500 is arranged between the third connection port and the exhalation power component 300;

[0027] The first selection valve 400 and the second selection valve 500 are selectively conducted. And when the first selection valve 400 is conducted, the inhalation power component 200 works to blow air into the simulated lung, and when the second selection valve 500 is conducted, the exhalation power component 300 works to extract and discharge the gas in the simulated lung.

[0028] During implementation, the simulated lung refers to a device that can simulate the breathing function of the human lung organ. For example, during inhalation, the simulated lung is used to temporarily store the inhaled gas, and during exhalation, the simulated lung is used to discharge the temporarily stored gas, realizing the simulation of the breathing function of the human lung.

[0029] The three-way connector 100 has a first connection port, a second connection port, and a third connection port that are interconnected. Among them, the first connection port is used to connect to the simulated lung, the second connection port is connected to the inhalation power component 200 through the first selection valve 400, and the third connection port is connected to the exhalation power component 300 through the second selection valve 500.

[0030] During implementation, the inhalation power component 200 and the second connection port of the three-way connector 100, as well as the exhalation power component 300 and the third connection port of the three-way connector 100, are respectively connected through a silicone tube. The first selection valve 400 and the second selection valve 500 are respectively arranged in the two silicone tubes. Among them, the inhalation power component 200 is used to transport gas in the direction of the three-way connector 100, the exhalation power component 300 is used to extract the gas discharged in the direction of the three-way connector 100, and one of the first selection valve 400 and the second selection valve 500 is turned on and the other is turned off. In other words, when the first selection valve 400 is turned on, the second selection valve 500 is turned off, and when the first selection valve 400 is turned off, the second selection valve 500 is turned on.

[0031] In some embodiments, the inhalation power component 200 and the exhalation power component 300 can adopt a turbine assembly or a fan assembly, as long as they can be used for gas transportation or extraction, and there is no limitation.

[0032] In other embodiments, the inhalation power component 200, the exhalation power component 300, the first selection valve 400, and the second selection valve 500 are all connected to a processor (not shown in the figure) to cooperate under the control of the processor to realize the function of simulating human lung breathing.

[0033] By setting information such as the frequency of simulated breathing, the human breathing function of a specific case can be simulated. Exemplarily, taking the inhalation-exhalation ratio of 1:1 as an example, that is, the inhalation cycle is X seconds, and the exhalation cycle is also X seconds. The value of X ranges from 1 to 4 seconds, such as 2 seconds or 3 seconds, etc., and there is no limitation.

[0034] Exemplarily, in some embodiments, taking X = 3.5 seconds as an example, the structural simulation breathing principle of the simulated human breathing frequency provided by the present application is as follows:

[0035] Inhalation cycle: Control the inhalation power component 200 to work, and control the first selection valve 400 to be turned on and the second selection valve 500 to be turned off for 3.5 seconds to transport gas to the simulated lung and simulate the inhalation function of the human lung.

[0036] Exhalation cycle: Control the exhalation power component 300 to work, and control the first selection valve 400 to be turned off and the second selection valve 500 to be turned on for 3.5 seconds to extract the gas in the simulated lung and discharge it, simulating the exhalation function of the human lung and completing a complete breathing cycle.

[0037] In some possible embodiments, taking X = 4.5 seconds as an example, the structure for simulating the human breathing frequency provided by the present application simulates the breathing principle as follows:

[0038] Inspiratory cycle: Control the inspiratory power component 200 to work, and control the first selector valve 400 to conduct while the second selector valve 500 is closed for 4.5 seconds to deliver gas to the simulated lung, simulating the inspiratory function of the human lung.

[0039] Expiratory cycle: Control the expiratory power component 300 to work, and control the first selector valve 400 to close while the second selector valve 500 is conducting for 4.5 seconds to extract and discharge the gas in the simulated lung, simulating the expiratory function of the human lung, completing a complete breathing cycle, capable of accurately simulating the human breathing function with high control precision. Moreover, the structure of the present application is simple and the implementation difficulty is low, effectively controlling the cost of the ventilator test tooling.

[0040] The structure for simulating the human breathing frequency provided by the present application includes a simulated lung, a three-way connector 100, an inspiratory power component 200, an expiratory power component 300, a first selector valve 400, and a second selector valve 500. The three-way connector 100 includes a first connection port, a second connection port, and a third connection port. Among them, the first connection port is connected to the simulated lung, the inspiratory power component 200 is connected to the second connection port through the first selector valve 400, and the expiratory power component 300 is connected to the third connection port through the second selector valve 500. When the first selector valve 400 is opened and the second selector valve 500 is closed, the inspiratory power component 200 works to blow air into the simulated lung, simulating the inspiratory state of the human body; when the first selector valve 400 is closed and the second selector valve 500 is opened, the expiratory power component 300 works to extract and discharge the gas in the simulated lung, simulating the expiratory state of the human body, completing a complete breathing cycle. The structure is simple and reliable, capable of providing accurate simulated human breathing monitoring parameter data for the ventilator, meeting the requirements of special case test cases for the ventilator.

[0041] In some alternative embodiments, an inspiratory flow sensor 600 is further provided on the pipeline between the first selector valve 400 and the second connection port, and an expiratory flow sensor 700 is further provided on the pipeline between the second selector valve 500 and the third connection port.

[0042] The flow sensor needs to be connected to the rear end of the selector valve for detecting the gas flow. During implementation, the implementation principle of the structure for simulating the human breathing frequency provided by the present application is as Figure 2 described. A complete breathing cycle includes an inspiratory cycle and an expiratory cycle.

[0043] In the inspiratory cycle: The inspiratory power component 200 (such as Figure 2 the inspiratory turbine shown) works. At this time, the first selector valve 400 (such as Figure 2 the selector valve 1 shown) is opened, and the second selector valve 500 (such asFigure 2 The shown gate valve 2) is closed, so that air can be blown towards the direction of the simulated lung. The gas flows through the inhalation flow sensor 600 and enters the simulated lung, thereby simulating the inhalation state of the patient.

[0044] During the exhalation cycle: The exhalation power component 300 (such as Figure 2 the shown exhalation turbine) works to extract the gas in the simulated lung and discharge it into the atmosphere. At this time, the second gate valve 500 is opened and the first gate valve 400 is closed. The gas in the simulated lung enters the exhalation flow sensor 700 from the three-way connector 100 and is discharged by the exhalation power component 300, thereby simulating the exhalation state of the patient.

[0045] By setting information such as the frequency and gas flow rate of the simulated respiration, the human respiration function of a specific case can be simulated. Exemplarily, taking the set inhalation flow rate of 5 L / min, the inhalation cycle of 1 second, and the exhalation cycle of 1 second as an example, the principle of the simulated respiration is as follows:

[0046] Inhalation cycle: Control the inhalation power component 200 to work at the set rotational speed, output a gas flow rate of 5 L / min, and control the first gate valve 400 to conduct for 1 second and then close; Exhalation cycle: Control the exhalation power component 300 to work at the set rotational speed, and control the second gate valve 500 to conduct for 1 second and then close to complete a complete respiration cycle.

[0047] In some embodiments, the structure for simulating the human respiration frequency provided by the present application further includes a bottom plate 810 and several side panels that enclose a receiving space with the bottom plate 810. The three-way connector 100, the inhalation power component 200, the exhalation power component 300, the first gate valve 400, and the second gate valve 500 are installed in the receiving space.

[0048] During implementation, the bottom plate 810 and several side panels are cooperatively installed to form the outer shell of the structure for simulating the human respiration frequency. The outer shell has a receiving space to accommodate the above-mentioned three-way connector 100, the inhalation power component 200, the exhalation power component 300, the first gate valve 400, and the second gate valve 500.

[0049] In some embodiments, the side panel includes at least one piece. For example, the side panel can be 2 pieces, 3 pieces / 4 pieces, or 5 pieces, etc. The number of side panels can be determined according to the shape of the bottom plate 810. For example, when the bottom plate 810 is circular, the side panel is a cylindrical plate. Similarly, when the bottom plate 810 is semi-circular, the side panel includes a square plate and a circular arc plate. Similarly, when the bottom plate 810 is triangular, the side panel includes three square plates.

[0050] In some alternative embodiments, taking the bottom plate 810 as a square plate as an example, the side panel includes four square plates, such as Figure 1As shown, the four square plates are the front plate 820, the rear plate 830, the left side plate 840, and the right side plate 850 respectively. Further, the structure for simulating the human breathing frequency provided in the present application further includes a top plate 860 that cooperates with several side panels and is used to cover the accommodation space. The housing is composed of a bottom plate 810, a front plate 820, a rear plate 830, a left side plate 840, a right side plate 850, and a top plate 860, and can protect the three-way connector 100, the inhalation power component 200, the exhalation power component 300, the first selection valve 400, and the second selection valve 500 installed in the accommodation space.

[0051] In some embodiments, the bottom plate 810 is provided with an inhalation hole (not shown in the figure), and the inhalation power component 200 is installed at the position of the inhalation hole. One of the side panels is provided with an exhalation hole 870, and the exhalation power component 300 is installed at the position of the exhalation hole 870. The side panel is also provided with an air outlet hole. The first connection port of the three-way connector 100 is connected to an air outlet pipe 900, and the air outlet pipe 900 passes through the air outlet hole and is connected to the simulated lung.

[0052] During use, in the inhalation cycle: the inhalation power component 200 operates. At this time, the first selection valve 400 is opened, and the second selection valve 500 is closed. Thus, air can be blown towards the simulated lung. The gas flows through the inhalation flow sensor 600, the three-way connector 100, and the air outlet pipe and enters the simulated lung, thereby simulating the inhalation state of the patient.

[0053] In the exhalation cycle: the exhalation power component 300 operates. At this time, the second selection valve 500 is opened, and the first selection valve 400 is closed. The gas in the simulated lung is extracted through the three-way connector 100 and the exhalation flow sensor 700 and discharged into the atmosphere, thereby simulating the exhalation state of the patient.
