[0032] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 scope of protection of this application.

[0033] The terms "first," "second," and the like in the specification and claims of this application and the accompanying drawings are used to distinguish between different objects, not to describe a particular order. Furthermore, the terms "including," "having," and any variations thereof, are intended to cover non-exclusive inclusions. For example, a process, method, system, product, or apparatus comprising a series of steps or elements is not limited to the listed steps or elements but may optionally include steps or elements not listed, or may optionally include other steps or elements inherent to the process, method, product, or apparatus.

[0034] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] Please refer to Figure 1, which is a structural block diagram of a plethysmograph box provided in an embodiment of the present application. As shown in Figure 1, a controller 100, a detection module 102, and a disinfection device 103 are provided in the box body 101 of the plethysmograph box 10. In other embodiments, the controller 100 can also be provided outside the box body 101. The controller 100 is electrically connected to the detection module 102 and the disinfection device 103, respectively. The detection module 102 is configured to perform lung volume detection under the control of the controller 100. The controller 100 is configured to: obtain status information of the plethysmograph box 10; determine whether the status information of the plethysmograph box 10 meets a preset condition, and control the disinfection device 103 to perform disinfection. Among them, the box body 101 refers to the main part of the plethysmograph box 10, and the shape of the box body 101 can be a rectangular parallelepiped or a cylinder, etc., which is not limited here; the disinfection device 103 can specifically be an alcohol spray device or an ultraviolet disinfection lamp. The disinfection device 103 can be arranged on the top wall inside the plethysmograph box body, and the inside of the plethysmograph box can be disinfected by spraying alcohol or irradiating with an ultraviolet disinfection lamp.

[0036] As shown in Figure 2 , the detection module 102 includes a mouthpiece 201, a filter 202, a shutoff valve 203, a flow sensor 204, a first pressure sensor 205, and a second pressure sensor 206. The mouthpiece 201 is connected to one end of the filter 202 to collect and initially filter the patient's exhaled or inhaled air. Both the mouthpiece 201 and the filter 202 are disposable. The other end of the filter 202 is connected to the first pressure sensor 205 and the flow sensor 204, respectively. A shutoff valve 203 is provided between the filter 202 and the flow sensor 204. When the shutoff valve 203 is closed, the first pressure sensor 205 measures the patient's oral pressure (Pm). When the shutoff valve 203 is open, the flow sensor 204 measures the flow rate or airflow velocity of the patient's exhaled or inhaled air. The second pressure sensor 206 measures the pressure (Pbox) within the plethysmography chamber. The flow sensor 204 , the first pressure sensor 205 , and the second pressure sensor 206 are all electrically connected to the controller 100 to transmit data signals to the controller 100 .

[0037] It can be seen that the plethysmograph box in the embodiment of the present application can automatically obtain the status information of the plethysmograph box, and automatically disinfect it through the disinfection device when the status information of the plethysmograph box meets the preset conditions. There is no need for the pulmonary function department staff to manually control the mechanical switch regularly to perform disinfection, which solves the current box disinfection needs during clinical pulmonary function testing.

[0038] In one possible example, as shown in FIG3 , the plethysmograph box 10 further includes a box door 104, and the box door 104 includes a door detection device 105, and the door detection device 105 is configured to obtain status information of the box door 104, and the door detection device 105 is electrically connected to the controller 100; the status information of the box door 104 includes an open state and a closed state; the controller 100 is configured to: receive the status information of the box door 104 obtained by the door detection device 105; determine that the status information of the box door 104 is a closed state, and control the disinfection device 103 to perform disinfection.

[0039] Specifically, the door detection device 105 can be an electromagnetic induction device, which can include two parts, one part installed on the box door 104 and the other part installed on the door frame. When the door is closed, the two parts are aligned, and the electromagnetic induction device detects whether the box door 104 is closed by changing the magnetic field. Specifically, the magnetic field state of the box door 104 when it is closed can be preset. When the electromagnetic induction device detects that the box door 104 reaches the preset magnetic field state, it sends an electrical signal to the controller 100. The controller 100 determines that the state information of the box door 104 is closed, and then controls the disinfection device 103 to perform disinfection. Optionally, the door detection device 105 can also be a Hall effect sensor, a proximity switch, etc., which is not limited here.

[0040] As can be seen, in this example, the plethysmography chamber uses the door detection device to obtain the chamber door status information and transmit it to the controller. When the controller determines that the chamber door status information is closed, it controls the disinfection device to perform disinfection. In this way, the plethysmography chamber can be automatically disinfected, solving the current chamber disinfection requirements during clinical pulmonary function testing.

[0041] In one possible example, as shown in FIG4 , a human body detection device 106 is further provided inside the box 101; the human body detection device 106 is configured to obtain human body detection information, and the human body detection device 106 is electrically connected to the controller 100; the human body detection information includes a human body in place state and a human body not in place state; the controller 100 is configured to: receive the human body detection information obtained by the human body detection device 106; determine that the human body detection information is a human body not in place state, and control the disinfection device 103 to perform disinfection.

[0042] Among them, the human body detection device 106 can specifically be a camera or infrared human body detector arranged inside the box 101, which directly identifies and detects the human body or other living things in the box; it can also be a pressure sensor arranged at the bottom of the box 101, which pre-collects and sets the pressure range when the human body is not in place through the pressure sensor. In actual use, when the pressure value is detected to increase, it is determined that the human body is in place, and an electrical signal is sent to the controller 100. The controller 100 determines that the human body detection information is that the human body is not in place, and then controls the disinfection device 103 to perform disinfection.

[0043] As can be seen, in this example, the plethysmography chamber uses a human body detection device to detect whether a person is inside the chamber and transmits the obtained human body detection information to the controller. If the controller determines that the human body detection information indicates that a person is not present, it controls the disinfection device to perform disinfection. In this way, the plethysmography chamber can be automatically disinfected, solving the current need for chamber disinfection during clinical pulmonary function testing.

[0044] In one possible example, the controller is configured to: obtain a disinfection start instruction, the status information of the box door, and the human body detection information; when it is determined that the status information of the box door is a closed state and the human body detection information is a human body not in place state, control the disinfection device to perform disinfection work according to the disinfection start instruction.

[0045] Specifically, please refer to Figure 5, which is a block diagram of a detection system provided by an embodiment of the present application. As shown in Figure 5, the detection system includes a controller 100 and a control terminal 20. The controller 100 is connected to the control terminal 20. The user performs a preset operation on the control terminal 20. The control terminal 20 generates a corresponding disinfection start instruction in response to the user's preset operation, and then sends the disinfection start instruction to the controller 100. When the controller 100 determines that the box door is closed and there is no one in the box, it controls the disinfection device 103 to perform disinfection according to the disinfection start instruction. Among them, the disinfection start instruction can specifically be an instruction for controlling the immediate start of the disinfection device 103, or it can be an instruction for controlling the start of the disinfection device 103 after a predetermined time is reached, which can be specifically determined by the user's operation on the control terminal 20. Among them, the control terminal 20 can be an intelligent device such as a mobile phone, a tablet computer, a personal computer, a remote control center, or a device such as a Bluetooth signal transmitter and an infrared signal transmitter.

[0046] As can be seen in this example, the user can use the control terminal to issue a disinfection start instruction to the plethysmograph box for immediate disinfection or scheduled disinfection. When the controller detects that the door is closed and no one is inside, it controls the disinfection device to perform disinfection according to the disinfection start instruction. The user can activate the disinfection function or scheduled disinfection function of the plethysmograph box on the control terminal, which increases the functional diversity and convenience of the plethysmograph box.

[0047] In a possible example, the plethysmograph box further includes a first timing module, which is electrically connected to the controller and configured to transmit the disinfection start instruction to the controller when a preset time point or a preset time interval is reached.

[0048] Specifically, as shown in Figure 6, the first timing module 107 is set on the box body 101. In other embodiments, the first timing module 107 can also be set on the box door 104, or integrated into the controller 100. The setting location is not limited to a single limit. One end of the first timing module 107 is connected to the control terminal 20, and the other end is connected to the controller 100. When the user performs a first preset operation on the control terminal 20, the control terminal 20 generates a disinfection start instruction corresponding to the first preset operation. The function corresponding to the first preset operation is to start the disinfection function of the plethysmography box at a preset time point or after a preset time interval. At this time, the control terminal 20 sends a disinfection start instruction to the first timing module 107. After reaching the preset time point or preset time interval, the first timing module 107 transmits the disinfection start instruction to the controller 100 to instruct the controller 100 to control the disinfection device 103 to perform the disinfection work. The first preset operation can, for example, be the operation of clicking the "Timed Disinfection" function button on the software interface of the control terminal 20. It should be noted that in actual application scenarios, since different pulmonary function departments have different disinfection requirements for the body scan box, each pulmonary function department can customize the disinfection start time based on their needs. Typically, regular disinfection is performed, that is, the above-mentioned preset time point is a fixed value, such as 5:00 p.m. every Tuesday, Thursday, and Saturday. Therefore, the first preset operation can also include manually setting the preset time point or preset time interval. Optionally, after the user sets the preset time point or preset time interval, the control terminal 20 will automatically save the user-set parameters. In this way, the next time the user executes the first preset operation, if there is no special need, the user can omit the manual setting of the preset time point or preset time interval, which is more convenient.

[0049] The user can also perform a second preset operation on the control terminal 20, which generates a disinfection start instruction corresponding to the second preset operation. The second preset operation immediately initiates disinfection of the plethysmography chamber. In this case, the control terminal 20 directly sends the disinfection start instruction to the controller 100, instructing the controller 100 to control the disinfection device 103 to perform disinfection. For example, the second preset operation can be clicking a "Disinfect Now" button on the software interface of the control terminal 20.

[0050] In other possible embodiments, the first timing module 107 is disposed on the surface of the plethysmograph box 10 and is only electrically connected to the controller 100. In this case, when a user performs an input operation on the first timing module 107, the first timing module 107 generates a disinfection start instruction after a preset time point or a preset time interval is reached, and sends the disinfection start instruction to the controller 100, instructing the controller 100 to control the disinfection device 103 to perform disinfection.

[0051] As can be seen in this example, when the user requests scheduled disinfection, the first timing module in the plethysmography box transmits a disinfection start instruction to the controller at a preset time point or time interval, instructing the controller to control the disinfection device to perform disinfection. This enriches the functional diversity of the plethysmography box and optimizes the user experience.

[0052] In one possible example, the status information of the plethysmograph box includes working status information, wherein the working status information includes a detection status and a stop detection status; the controller is further configured to: when determining that the working status information is a detection status, control the disinfection device to switch to a stop disinfection state.

[0053] Among them, when the working status information of the plethysmograph box is the detection state, it indicates that the plethysmograph box is performing work tasks such as lung volume detection. In order to avoid affecting the test results or avoiding affecting the object being tested, disinfection should not be performed at this time. That is, when the controller detects that the working status information of the plethysmograph box is the detection state, it controls the disinfection device to switch to the stop disinfection state.

[0054] It can be seen that in this example, when the controller detects that the working status information of the plethysmograph box is the detection state, it controls the disinfection device to switch to the stop disinfection state to avoid affecting the detection results or the object being measured, thereby improving the intelligence and safety of the plethysmograph box.

[0055] In one possible example, the plethysmograph box further includes a second timing module, which is configured to obtain the disinfection duration of the plethysmograph box. The second timing module is electrically connected to the controller, and the controller is configured to control the disinfection device to switch to a stop disinfection state when determining that the disinfection duration reaches a preset time threshold.

[0056] Specifically, as shown in Figure 7, the second timing module 108 is arranged on the box body 101. In other embodiments, the second timing module 108 can also be arranged on the box door 104, or integrated into the controller 100. The setting position is not uniquely limited. One end of the second timing module 108 is connected to the control terminal 20, and the other end is connected to the controller 100. When the user performs the third preset operation on the control terminal 20, the control terminal 20 generates a disinfection stop instruction corresponding to the third preset operation. The function corresponding to the third preset operation is: when the disinfection duration reaches the preset time threshold, stop disinfection. At this time, the control terminal 20 sends a disinfection stop instruction to the second timing module 108. The second timing module 108 continuously obtains the disinfection duration, and when it detects that the disinfection duration reaches the preset time threshold, transmits the disinfection stop instruction to the controller 100 to instruct the controller 100 to control the disinfection device 103 to switch to the disinfection stop state. The third preset operation can, for example, be the operation of clicking the "Timed Off" function button on the software interface of the control terminal 20. It should be noted that in actual application scenarios, since different pulmonary function departments have different disinfection requirements for the body scanner, each pulmonary function department can customize the above-mentioned preset time threshold, that is, the disinfection duration, based on their needs. Therefore, the third preset operation may also include manual setting of the preset time threshold. Optionally, after the user sets the preset time threshold, the control terminal 20 will automatically save the user-set parameters. In this way, the user can omit the manual setting of the preset time threshold the next time the third preset operation is performed unless there is a special requirement, which is more convenient.

[0057] In another possible example, the second timing module 108 is disposed on the surface of the plethysmography box 10 and is electrically connected only to the controller 100. In this case, the user performs an input operation on the second timing module 108 to instruct the plethysmography box to stop disinfection when the disinfection duration reaches a preset time threshold. The second timing module 108 obtains the disinfection duration of the plethysmography box and transmits the disinfection duration to the controller 100. When the controller 100 determines that the disinfection duration has reached the preset time threshold, it controls the disinfection device 103 to switch to a stopped disinfection state.

[0058] As can be seen, in this example, the user can customize the disinfection duration. When the disinfection duration reaches a preset threshold, the second timing module in the plethysmography box transmits a disinfection stop instruction to the controller, instructing the controller to switch the disinfection device to a stopped disinfection state. This allows for customizable disinfection duration settings, enriching the functionality of the plethysmography box and optimizing the user experience.

[0059] In one possible example, the plethysmograph box further includes a third timing module and an alarm module, the controller is electrically connected to the third timing module and the alarm module, the third timing module is configured to transmit a disinfection reminder instruction to the controller when a preset time point or a preset time interval is reached, and the controller is configured to control the alarm module to alarm according to the disinfection reminder instruction.

[0060] Specifically, as shown in Figure 8, the third timing module 109 and the alarm module 110 are both provided on the housing 101. In other embodiments, the third timing module 109 and the alarm module 110 can also be provided on the door 104. The third timing module 109 can also be integrated into the controller 100, and the location of the arrangement is not limited to a single one. One end of the third timing module 109 is connected to the control terminal 20, and the other end is connected to the controller 100. The alarm module 110 is connected to the controller 100. When the user performs the fourth preset operation on the control terminal 20, the control terminal 20 generates a disinfection reminder instruction corresponding to the fourth preset operation. The function implemented by the fourth preset operation is: reminding disinfection when a preset time point or a preset time interval is reached. At this time, the control terminal 20 sends a disinfection reminder instruction to the third timing module 109. When the preset time point or the preset time interval is reached, the third timing module 109 sends a disinfection reminder instruction to the controller 100 to instruct the controller 100 to control the alarm module 110 to alarm according to the disinfection reminder instruction. Optionally, the alarm module 110 may be a display screen embedded in the door, with the alarm mode being to control the display interface of the display screen to issue a pop-up alarm; it may also be a buzzer, with the alarm mode being to control the output of a preset sound; or it may be an alarm light, with the alarm mode being to control the flashing of the alarm light, the fourth preset operation may be, for example, clicking a "scheduled reminder" function button on the software interface of the control terminal 20.

[0061] In other possible examples, the third timing module 109 is disposed on the surface of the plethysmograph box 10 and is only electrically connected to the controller 100. In this case, the user performs an input operation on the third timing module 109 to instruct the plethysmograph box to remind disinfection at a preset time point or a preset time interval. When the preset time point or the preset time interval is reached, the third timing module 109 sends a disinfection reminder instruction to the controller 100, instructing the controller 100 to control the alarm module 110 to sound an alarm according to the disinfection reminder instruction.

[0062] It can be seen that in this example, the user can customize the reminder time point for disinfection of the plethysmograph box, so that the plethysmograph box can remind the user when disinfection is required, thereby enhancing interactivity, enriching the functional diversity of the plethysmograph box, and optimizing the user experience.

[0063] In one possible example, the plethysmograph box further includes an input module configured to receive a trigger instruction input by a user, the input module is electrically connected to the controller, and the controller is configured to change the working state of the disinfection device according to the trigger instruction input by the user.

[0064] Specifically, as shown in FIG9 , the input module 111 is disposed on the housing 101. In other embodiments, the input module 111 may also be disposed on the door 104. The location of the arrangement is not limited thereto. The input module 111 is connected to the controller 100. The input module 111 may be a touch screen embedded in the door or a mechanical switch. When a user performs a relevant operation on the touch screen or the mechanical switch, the touch screen receives a trigger instruction corresponding to the relevant operation performed by the user and transmits the trigger instruction to the controller 100 to instruct the controller 100 to change the working state of the disinfection device 103.

[0065] As can be seen, in this example, the plethysmography box also includes an input module that allows for direct human-computer interaction. Even when the control terminal is powered off, the user can directly change the disinfection device's operating state by performing operations on this input module. This improves scenario adaptability and operational convenience, enriches the plethysmography box's functionality, and optimizes the user experience.

[0066] It is understandable that in the above embodiments, when the disinfection device is performing disinfection work, the door is placed in a state where it cannot be opened to ensure the safety of personnel.

[0067] The following describes a plethysmography box according to an embodiment of the present application through an example diagram.

[0068] Please refer to Figure 10, which is an example diagram of a plethysmograph box provided in an embodiment of the present application. As shown in Figure 10, the box body of the plethysmograph box is provided with an electromagnetic door sensor, an ultraviolet disinfection lamp, a human body sensing device, an ultraviolet lamp mechanical switch, a filter, a mouthpiece, a shut-off valve (Shutter), a flow sensor, a pressure sensor for measuring the pressure inside the box (Pbox), and a pressure sensor for measuring the oral pressure (Pm). The functional descriptions of the above-mentioned devices / structures are detailed in the above-mentioned embodiments and will not be repeated here. The plethysmograph box is capable of two-way communication with a personal computer (PC) so that the user can automatically control the disinfection of the plethysmograph box through the PC.
