Description

Technical Field

[0002] A respiratory gas monitor, also known as a respiratory gas monitoring device, is a device used to monitor a patient's respiratory gases. It can monitor indicators such as respiratory rate, end-expiratory carbon dioxide concentration (EtCO2), and end-expiratory oxygen concentration (EtO2) in real time, providing doctors with important respiratory function information. In addition, it can also monitor the concentration of anesthetic gases used by the patient. Because anesthetic gases require highly precise concentrations for patients with different physical conditions, the system response time needs to be tested before using a respiratory gas monitor to ensure that the device's response time to various gases is within the required range. However, existing devices can only test each respiratory gas monitor individually, significantly reducing testing efficiency. Utility Model Content

[0054] The present invention will be further described below with reference to specific embodiments and accompanying drawings. More details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention can obviously be implemented in many other ways different from those described herein. Those skilled in the art can make similar extensions and derivations based on actual application situations without departing from the spirit of the present invention. Therefore, the scope of protection of the present invention should not be limited by the content of this specific embodiment.

[0055] In related technologies, total response time testing devices can only test respiratory gas monitors individually, which greatly reduces testing efficiency. Therefore, to solve this problem, the technical solution of this application was developed, and the following is a combination of... Figures 1-12 To elaborate.

[0056] Example 1

[0057] Figure 1 This is a structural diagram of an embodiment of the testing device of this utility model. As shown in the figure, this application discloses a total response time testing device for a respiratory gas monitor, including: a base 100, a timer 200 and a monitor 300.

[0058] The base 100 is the installation base of the device of this application. The base 100 includes a first base block 101 and a second base block 102. The height of the first base block 101 is greater than that of the second base block 102. Two placement slots are provided in the first base block 101, and test gas cylinders 10 are placed in the placement slots. The monitor 300 and timer 200 are located in the second base block 102.

[0059] The second base block 102 has a placement area for the respiratory gas monitors 20 along one side of the width direction Y of the testing device. Multiple respiratory gas monitors 20 are located in this placement area and are arranged sequentially along the length direction X of the testing device. A portion of the first base block 101 and the second base block 102 are arranged sequentially along the length direction X of the testing device. Another portion of the first base block 101 is offset from the second base block 102 along the length direction X and corresponds to the placement area of ​​the respiratory gas monitors 20 along the length direction X. This structure is more compact and allows for the limiting of the respiratory gas monitors 20. The base 100 is provided with a medium pipeline for connecting the test gas cylinder 10 and the gas delivery tubes 21 of the multiple respiratory gas monitors 20.

[0060] The monitor 300, timer 200 and multiple respiratory gas monitors 20 are arranged sequentially along the width direction Y, so that the monitoring area of ​​the monitor 300 will cover the timer 200 and each respiratory gas monitor 20.

[0061] During the test, test gas cylinder 10 is supplied with test gas to each respiratory gas monitor 20 through a medium pipeline. Monitor 300 monitors the parameters displayed on the screens of each respiratory gas monitor 20 and obtains the response time of each monitor 20 based on the timer 200. Specifically:

[0062] Each respiratory gas monitor 20 is numbered, for example, #1 to #4. Taking #1 as an example, the monitor 300 captures and stores images of the parameters displayed on the screen of #1 to obtain image information. Then, the stored video footage is analyzed frame by frame. When the gas concentration at the sampling point changes stepwise to 90% of the final gas reading displayed on the monitor, the system is required to respond. The corresponding response time of #1 is then obtained based on the counting time of the timer 200. Similarly, the monitor 300 captures and stores images of the screen of #2 to obtain image information. The stored video footage is then analyzed frame by frame, and the corresponding response time of #2 is obtained based on the counting time of the timer 200. The response times of #1 to #4 can be obtained in the same way.

[0063] In summary, in the first aspect, the testing device of this application can realize batch testing of multiple respiratory gas monitors 20, thereby improving testing efficiency; in the second aspect, the response time of multiple respiratory gas monitors 20 can be tested using only one timer 200 during the testing process, saving material costs.

[0064] Optionally, such as Figure 1 , Figure 2 and Figure 6 As shown, the medium pipeline includes multiple branch pipelines 110, each branch pipeline 110 is equipped with a branch valve body 410, and both the branch pipelines 110 and the branch valve body 410 can be embedded in the base 100. The branch valve body 410 can be a solenoid valve, and one end of the branch pipeline 110 protrudes outside the base 100 to serve as a pipe connector 111.

[0065] The device in this application also includes an opening and closing control component, which includes a proximity switch 510. The opening and closing control component is electrically connected to a branch valve body 410. During testing, the threaded connection between the air inlet tube 21 of the breathing gas monitor 20 and the corresponding pipe joint 111 is activated, triggering the proximity switch 510. When the proximity switch 510 of the opening and closing control component is activated, the branch valve body 410 will open, thereby enabling communication between the test gas cylinder 10 and the breathing gas monitor 20. If the air inlet tube 21 is not connected to the pipe joint 111, the opening and closing control component is not activated, the branch valve body 410 is closed, and the gas in the test gas cylinder 10 will not be output from the pipe joint 111 that is not connected to the air inlet tube 21.

[0066] Optionally, the opening and closing control component can be a contact-type triggering device. However, to improve control accuracy, this application may also set the opening and closing control component as a non-contact triggering device, as detailed below:

[0067] like Figures 2-4 As shown, the opening and closing control assembly includes a proximity switch 510, an elastic element 520, and a limit recognition ring 530. The elastic element 520 can be a spring, and the limit recognition ring 530 is a metal detector. The proximity switch 510 is located on the base 100 and electrically connected to the branch valve body 410. The elastic element 520 and the limit recognition ring 530 are sequentially movably sleeved on the pipe connector 111 in a direction away from the proximity switch 510. When the pipe connector 111 is threadedly connected to the air guide pipe 21, the air guide pipe 21 will abut against the limit recognition ring 530. The limit recognition ring 530 will overcome the resistance of the elastic element 520 and approach the proximity switch 510. When the limit recognition ring 530 enters the detection area of ​​the proximity switch 510, the proximity switch 510 can be triggered, and then the proximity switch 510 sends an electrical command to open the branch valve body 410. When the air duct 21 is removed from the pipe joint 111, the elastic element 520 returns to its original deformation to drive the limit recognition ring 530 away from the proximity switch 510 and outside the detection area of ​​the proximity switch 510. At this time, the proximity switch 510 is not triggered and the branch valve body 410 is closed.

[0068] Optionally, such as Figure 1 and Figure 6 As shown, the media pipeline includes a main pipeline 120, one side of which extends beyond the base 100 for connection to the test gas cylinder 10. The other side of the main pipeline 120 is connected to multiple branch pipelines 110. A main valve body 420 is mounted on the main pipeline 120, and a main switch 600 electrically connects the main valve body 420 and the timer 200 to the base 100. When the main switch 600 is opened, the main valve body 420 opens, allowing test gas to flow from the test gas cylinder 10 to the breathalyzer 20. Simultaneously, the timer 200 starts timing to ensure accuracy.

[0069] Optionally, such as Figure 1 and Figure 2 As shown, the air tube 21 supporting the respiratory gas monitor 20 is relatively long and made of a soft material. To prevent the air tube 21 from bending or collapsing during testing, the device of this application also includes a tube support assembly 700 disposed on the base 100. The tube support assembly 700 is used to support the air tube 21, thereby preventing the air tube 21 from bending or collapsing, and thus ensuring that the test gas is effectively input into the respiratory gas monitor 20.

[0070] Optionally, the catheter support assembly 700 includes a support body 710 and a catheter fixation member 720. The support body 710 is disposed on the base 100, and the catheter fixation member 720 is disposed directly or indirectly on the support body 710. The catheter fixation member 720 is used to support the air tube 21.

[0071] Furthermore, the catheter fixation component 720 can be directly or indirectly disposed on the support body 710. For example, the catheter support assembly 700 also includes an adjustment component 730 movably connected to the support body 710, and the catheter fixation component 720 is disposed on the adjustment component 730, thereby allowing the position of the catheter fixation component 720 to be adjusted via the adjustment component 730. This facilitates the installation of the airway 21 and the catheter fixation component 720, and also allows the position of the airway 21 to be adjusted via the adjustment component 730, preventing obstruction of the respiratory monitor 20 screen.

[0072] Optionally, the support body 710 includes a first frame 711 disposed on the base 100 and a second frame 712 connected to the first frame 711. The first frame 711 and the second frame 712 extend in different directions. For example, the first frame 711 extends along the height direction Z of the device, and the second frame 712 extends along the length direction X, which is the direction in which multiple respiratory gas monitors 20 are arranged sequentially. The adjusting member 730 is a movable sleeve that is movably fitted onto the second frame 712. The movable sleeve can move along the extension direction of the second frame 712, thereby realizing the horizontal position adjustment of the air tube 21 along with the tube fixing member 720.

[0073] Furthermore, such as Figure 6 and Figure 7 As shown, in order to lock the adjusting member 730 of the movable sleeve structure on the second frame 712, a set screw 740 is threaded onto the adjusting member 730. Tightening the set screw 740 can fix the adjusting member 730 on the second frame 712, and loosening the set screw 740 can allow the adjusting member 730 to move on the second frame 712.

[0074] Optionally, regarding the specific structure of the catheter fixation member 720, the catheter fixation member 720 can be set as any structure that can fix the position of the air tube 21, such as a fixing seat or a tube clamp. In this application, the following setting is adopted:

[0075] like Figure 5 As shown, the catheter fixing member 720 is an elastic sleeve with an opening. The area enclosed by the elastic sleeve is used for the air tube 21 to pass through. The size of the area enclosed by the catheter fixing member 720 varies with the size of the opening. During installation, the elastic deformation of the elastic sleeve can be used to insert the air tube 21 into the catheter fixing member 720 through the opening. The catheter fixing member 720 will then close and cover the outer circumference of the air tube 21, so that the catheter fixing member 720 can clamp, fix, and guide the air tube 21 during installation. During disassembly, the elastic deformation of the elastic sleeve can also be used to remove the air tube 21 from the opening of the catheter fixing member 720, so as to separate the air tube 21 from the catheter fixing member 720 for easy disassembly and assembly.

[0076] Optionally, such as Figure 8 As shown, the device of this application also includes a monitor carrier 800 for carrying the respiratory gas monitor 20. The monitor carrier 800 is detachably connected to the base 100. The monitor carrier 800 can be configured as a tray structure. Multiple respiratory gas monitors 20 can be installed on the base 100 as a whole with the monitor carrier 800, or can be completely removed from the base 100, thereby improving the ease of installation and removal.

[0077] Optionally, such as Figures 8-10 As shown, the device of this application also includes a support member 900, through which the monitor carrier 800 is detachably connected to the base 100. For example, the support member 900 is fixed to the base 100 and detachably connected to the monitor carrier 800; or the support member 900 is fixed to the monitor carrier 800 and detachably connected to the base 100; or the support member 900 is detachably connected to both the monitor carrier 800 and the base 100. This facilitates the assembly and disassembly of the base 100 and the monitor carrier 800.

[0078] Furthermore, the support member 900 can be configured as a retractable electric actuator, and the bottom surface of the base 100 is provided with a pull-out groove, in which the support member 900 is fixedly installed. The bottom surface of the monitor carrier 800 is provided with a slot 801. When installing the monitor carrier 800, the support member 900 can extend out of the base 100 to engage with the slot 801; when disassembling the monitor carrier 800, the support member 900 is separated from the slot 801, and then the support member 900 is retracted into the pull-out groove of the base 100 for storage.

[0079] Furthermore, the base 100 has a pull-out groove, a support 900, and a slot 801 that correspond one-to-one, and multiple slots are provided for each to improve the support stability of the monitor support 800.

[0080] Optionally, the device of this application also includes a monitor fixing member 810 disposed on the monitor carrier 800. The monitor fixing member 810 is used to fix the respiratory gas monitor 20, for example, the monitor fixing member 810 is configured as a clamp, strap or other structure.

[0081] Taking the monitor fixing component 810 as a strap as an example, multiple monitor fixing components 810 can be set. During installation, the two ends of the monitor fixing component 810 are connected to the monitor carrier component 800. Then, the respiratory gas monitors 20 pass through the area enclosed by the monitor fixing component 810 and the monitor carrier component 800 one by one. Subsequently, the monitor fixing component 810 binds and fixes the respiratory gas monitors 20 to the monitor carrier component 800 to prevent abnormal separation between the monitor carrier component 800 and the respiratory gas monitors 20. During disassembly, the monitor fixing component 810 can be separated from the monitor carrier component 800 first, thereby unbinding the respiratory gas monitors 20, and then the respiratory gas monitors 20 can be taken out from the monitor carrier component 800.

[0082] Optionally, the surface of the monitor carrier 800 is provided with friction protrusions 802, which are used to contact the respiratory gas monitor 20 to increase the friction between the monitor carrier 800 and the respiratory gas monitor 20 and prevent abnormal movement of the respiratory gas monitor 20.

[0083] Example 2

[0084] Figure 11 This is a structural diagram of another embodiment of the testing device of this utility model; Figure 12 This is the testing device of this utility model. Figure 11 The top view is shown in the figure. The difference between this embodiment and embodiment 1 is that:

[0085] Each timer 200 corresponds one-to-one with a respiratory gas monitor 20. Each timer 200 records the response time of each respiratory gas monitor 20, as detailed below:

[0086] Each respiratory gas monitor 20 is numbered, for example, #1 respiratory gas monitor to #4 respiratory gas monitor. At the same time, the timers 200 are numbered, for example, #1 timer to #4 timer.

[0087] Taking the #1 respiratory gas monitor as an example, the monitor 300 captures and stores images of the parameters displayed on the screen of the #1 respiratory gas monitor to obtain image information. Then, it analyzes the stored video frame by frame. When the step change of the gas concentration at the sampling point reaches 90% of the final gas reading measured by the respiratory gas monitor, it determines that the system should respond. Then, it obtains the corresponding response time of the #1 respiratory gas monitor based on the counting time of the #1 timer at this time. Similarly, the monitor 300 captures and stores images of the screen displayed on the #2 respiratory gas monitor to obtain image information. Then, it analyzes the stored video frame by frame and obtains the corresponding response time of the #2 respiratory gas monitor based on the counting time of the #2 timer at this time. The response times of the #1 to #4 respiratory gas monitors can be obtained in the same way.

Any person skilled in the art can make possible variations and modifications without departing from the spirit and scope of the present invention.
