[0033] Please see Figure 6 , Figure 7 , Figure 8 and Figure 9The detection device 2 includes a rotating part 22 and an adjusting part 23. The rotating part 22 is mounted on the adjusting part 23. The adjusting part 23 includes a limiting ring 24, a limiting groove 25, an arc-shaped connecting plate 26, a U-shaped fixing frame 27, a second drive gear 28, and a second motor 29. The limiting groove 25 is formed through the limiting ring 24. The arc-shaped connecting plate 26 is fixedly connected to the outside of the limiting ring 24. The U-shaped fixing frame 27 is evenly fixedly installed at the bottom end of the limiting ring 24. The second motor 29 is fixedly installed on the limiting ring 24. The second drive gear 28 is rotatably installed on the limiting ring 24, and the drive end of the second motor 29 is fixedly connected to the second drive gear 28. The running second motor 29 can drive the second drive gear 28 to rotate. The rotating second drive gear 28 can drive the rotating ring 30 to move inside the limiting groove 25 towards the pointer via the second rotating adjusting gear ring 31. The rotating part 22 can be rotated in a fixed direction and at a specified angle, allowing the orientation and position of the display screen 33 to be easily adjusted. This enables medical personnel to remotely and automatically control the position of the display screen 33 from various locations, facilitating the observation of the detected values. The rotating part 22 includes a rotating ring 30, a second rotating adjustment gear ring 31, a carbon dioxide infrared sensor 32, a display screen 33, and a fixed frame 34. The second rotating adjustment gear ring 31 is fixedly installed at the bottom of the rotating ring 30, and the fixed frame 34 is fixedly connected to the rotating ring 30. The carbon dioxide infrared sensor 32 is fixedly connected to the fixed frame 34 by bolts, and the display screen 33 is fixedly connected to the carbon dioxide infrared sensor 32. The display screen 33 is electrically connected to the carbon dioxide infrared sensor 32 through wires. The values and information detected by the carbon dioxide infrared sensor 32 can be displayed accurately and in real time on the display screen 33, facilitating the observation of the test results.
[0034] The rotating ring 30 is rotatably engaged inside the limiting slot 25. The second drive gear 28 is meshed with the second rotating adjusting gear ring 31. The arc-shaped connecting plate 26 is fixedly connected to the upper end of the first electric push rod 7. The arc-shaped connecting plate 26 can be raised and lowered by the first electric push rod 7.
[0035] The limiting lifting column 18 is slidably engaged in the middle of the limiting plate 9, the second electric push rod 21 is fixedly installed on the support platform 5, and the delivery hose 3 is connected to the carbon dioxide infrared sensor 32, so that the exhaled carbon dioxide can be delivered to the carbon dioxide infrared sensor 32.
[0036] The carbon dioxide infrared sensor 32 is wirelessly connected to the controller 10. The controller 10 is connected to the voice controller 12, the voice alarm 13, the flashing alarm 14, the second electric push rod 21, and the first electric push rod 7 via wires, which can realize automatic control.
[0037] The working principle of Example 1 is as follows: During use, the delivery hose 3 is connected to the carbon dioxide infrared sensor 32, so that when the breathing mask 4 is placed over the patient's nose and mouth, the carbon dioxide exhaled can be delivered to the interior of the carbon dioxide infrared sensor 32 through the breathing mask 4 and the delivery hose 3. The concentration of CO2 is calculated by measuring the absorption intensity of CO2 in the sample. The carbon dioxide infrared sensor 32 emits a beam of infrared light, which passes through the sample and is received by the receiver. If the exhaled gas contains CO2, when the infrared light passes through the sample containing CO2, some photons will be absorbed by the CO2 molecules, and the rest will be received by the receiver. The concentration of CO2 in the sample can be calculated based on the ratio of the number of photons absorbed by the CO2 molecules to the total number of incident photons. Furthermore, the values and information detected by the carbon dioxide infrared sensor 32 can be displayed accurately in real time on the display screen 33, which facilitates the observation of the detection results.
[0038] When the values and indicators detected by the carbon dioxide infrared sensor 32 are outside the normal range, the information detected by the carbon dioxide infrared sensor 32 is transmitted to the controller 10. Then, the controller 10 controls the second electric push rod 21 and the first motor 16 to run. The second electric push rod 21 drives the limit lifting column 18 to slide upward along the limit plate 9. At this time, the lifting platform 15 is raised, and the first motor 16 drives the first drive gear 17 to rotate forward and backward. The forward and reverse rotation of the first drive gear 17 can drive the support connecting column 20 and the lifting platform 15 to rotate forward and backward through the first rotation adjustment gear ring 19. At this time, the voice alarm 13 and the flashing alarm 14 will run and rotate. The voice alarm 13 and the flashing alarm 14 can realize dual alarm prompts of voice and light, and swing during the prompt.
[0039] When it is necessary to observe the values displayed on the display screen 33, a voice command can be issued. Upon receiving the command, the voice controller 12 transmits the information to the controller 10. The controller 10 then controls the second motor 29 to run. The running second motor 29 can drive the second drive gear 28 to rotate. The rotating second drive gear 28, through the second rotation adjustment gear ring 31, can drive the rotating ring 30 to rotate in a specified direction and angle within the limit slot 25. This allows the orientation and position of the display screen 33 to be easily adjusted, enabling medical personnel to remotely and automatically control the position of the display screen 33 from various locations for convenient observation of the detected values. Furthermore, the first electric push rod 7 can control the lifting and lowering of the detection device 2, thereby controlling the height of the display screen 33.
[0040] Example 2
[0041] Based on Example 1, such as Figure 10As shown, a support ring platform 37 is fixedly installed on the outside of the limiting plate 9. A protective cover 36 is placed on the upper part of the support ring platform 37. A lifting handle 35 is fixedly installed in the middle of the upper end of the protective cover 36. The prompting device 1 and the detection device 2 are located inside the protective cover 36.
[0042] In implementing this embodiment, the protective cover 36 can be lifted and removed by pulling the handle 35. After the protective cover 36 is placed on the support ring platform 37, it can protect the entire indicator device 1 and the detection device 2, so that dust will not fall into the indicator device 1 and the detection device 2. This prevents dust from entering the device during placement and greatly extends its service life.
