Description

Technical Field

[0001] The utility model relates to the technical field of measurement and control equipment, and specifically to a ventilator measurement and control equipment based on photoacoustic spectroscopy. Background Art

[0002] Photoacoustic spectroscopy ventilator measurement and control equipment is usually used to monitor and adjust the patient's breathing conditions to improve the therapeutic effect and safety of the ventilator. This device combines photoacoustic spectroscopy technology with sensors and control systems to achieve real-time monitoring and adjustment of the patient's respiratory parameters.

[0003] The ventilator measurement and control equipment of photoacoustic spectroscopy is generally connected to the ventilator through a detection pipeline, and the detection pipeline is connected to the outlet pipe of the ventilator. Using the data collected by the sensor in the detection pipeline, the control system can analyze and feedback to the ventilator in real time, adjust the airflow parameters, and ensure that the patient receives appropriate ventilation support.

[0004] When the detection pipeline on the traditional measurement and control equipment is connected to the exhaust pipeline of the ventilator, the detection pipeline is usually placed directly and randomly. This placement method is prone to causing the detection pipeline to shake due to factors such as impact from external objects during use. The resulting shaking can easily affect the detection results of the sensor in the detection pipeline, thereby causing the control data of the measurement and control equipment to send out erroneous signals, thereby reducing the patient's comfort.

On the measurement and control device 1, an extrusion component is fixedly connected to one side of the adjustment component close to the measurement and control tube 12. When the measurement and control tube 12 is installed and used, the measurement and control tube 12 is first inserted into the inner side of the extrusion component in sequence, and then the extrusion component is driven to move by the adjustment component to allow the extrusion component to squeeze and limit the measurement and control tube 12. The measurement and control tube 12 can be positioned and limited to avoid shaking caused by external impact or traction, thereby improving the detection stability of the sensor inside the measurement and control tube 12 and improving the comfort of the patient using the ventilator for treatment.

[0021] like Figure 1 As shown, a limiting component is provided on the outer side of the upper end of the measuring and control tube 12, and a connecting component is fixedly connected to one end of the limiting component close to the measuring and control tube 12, and the inner side of the connecting component is sleeved on the outer side of the measuring and control tube 12. When the measuring and control tube 12 and the air outlet pipe 13 are connected and installed, the air outlet pipe 13 is passed through the inside of the limiting component, and then the upper end of the measuring and control tube 12 is passed through the connecting component and then installed and connected with the air outlet pipe 13. When a foreign object hits, the limiting component and the connecting component are used to protect the connection between the measuring and control tube 12 and the air outlet pipe 13 to prevent the measuring and control tube 12 and the air outlet pipe 13 from loosening due to the impact.

[0022] like Figure 3 As shown, the adjustment component includes a connecting plate 2 arranged on the outer side of both ends of the measuring and controlling tube 12, and the side of the connecting plate 2 close to the measuring and controlling device 1 is fixedly connected to the measuring and controlling device 1, a screw plate 21 is arranged on the outer side of the end of the connecting plate 2 away from the measuring and controlling tube 12, and a transmission rod 22 is fixedly connected to the side of the screw plate 21 close to the connecting plate 2, the outer side of the middle end of the transmission rod 22 is inserted and rotatably connected in the connecting plate 2, and the side of the transmission rod 22 away from the screw plate 21 is fixedly connected to an external threaded rod 23, and the end of the external threaded rod 23 away from the transmission rod 22 is inserted and meshed with the inner A slider 25 is fixedly connected to the outside of the threaded rod 24 and one end of the internal threaded rod 24 close to the external threaded rod 23. The end of the slider 25 away from the internal threaded rod 24 is inserted and slid on the inner side of the connecting plate 2 to twist the screw plates 21 on both sides in turn. After the screw plates 21 rotate, the transmission rod 22 and the external threaded rod 23 are driven to rotate. After the external threaded rod 23 rotates, it engages with the thread of the internal threaded rod 24, so that the internal threaded rod 24 drives the extrusion assembly to move under the limit of the slider 25, so as to drive the extrusion assembly to move and limit the extrusion of the measurement and control tube 12.

[0023] like Figure 3 As shown, the extrusion assembly includes a positioning plate 3 fixedly connected to the side of the internal threaded rod 24 away from the external threaded rod 23, and the side of the positioning plate 3 away from the internal threaded rod 24 is fixedly connected to a rubber pad 31, and the side of the rubber pad 31 away from the positioning plate 3 is sleeved and fitted on the outside of the measurement and control tube 12. The internal threaded rod 24 drives the positioning plate 3 and the rubber pad 31 to move under the limit of the slider 25. After the rubber pad 31 moves, it squeezes and limits the outside of the measurement and control tube 12, so as to facilitate the use of the positioning plate 3 and the rubber pad 31 to squeeze and position the measurement and control tube 12.

[0026] Working principle: When installing and connecting the measurement and control tube 12 and the air outlet pipe 13 on the measurement and control equipment, first pass the measurement and control tube 12 through the rubber pad 31 in turn, and then screw the screw plates 21 on both sides in turn. After the screw plates 21 rotate, they drive the transmission rod 22 and the external threaded rod 23 to rotate. After the external threaded rod 23 rotates, it engages with the thread of the internal threaded rod 24, so that the internal threaded rod 24 drives the positioning plate 3 and the rubber pad 31 to move under the limit of the slider 25. After the rubber pad 31 moves, it squeezes and limits the outer side of the measurement and control tube 12. After the rubber pads 31 on both sides squeeze and limit the measurement and control tube 12, the upper end of the measurement and control tube 12 passes through the second sleeve 51, and the air outlet pipe 13 passes through the first sleeve 41, and then the measurement and control tube 12 is installed at the lower end of the air outlet pipe 13.
