Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and particularly relates to a real-time respiratory assistance monitoring device for thoracic surgery nursing and a monitoring method thereof. Background Art

[0002] After thoracic surgery (such as lung cancer resection, esophageal surgery, etc.), the recovery of the patient's respiratory function is a key issue. Such surgeries may affect the patient's lung function and respiratory ability. To ensure that the patient can smoothly pass through the postoperative stage, it is necessary to monitor the patient's respiratory status in real time, timely adjust nursing measures to reduce the risk of complications, and improve the quality of postoperative recovery.

[0003] Most of the existing respiratory monitoring devices use airflow sensors (such as thermal or piezoelectric sensors) to measure gas flow, which can directly monitor respiratory data. However, their monitoring effect on the respiratory intensity and respiratory frequency of patients is poor, and the monitoring data is relatively single. At the same time, when the oxygen production of the existing respiratory monitoring device decreases and maintenance is required, the body needs to be disassembled to replace relevant components, and professional operation is required for replacement. For traditional medical staff, it is difficult in terms of maintenance. Summary of the Invention

[0015] In a preferred solution, the gas flow inside the secondary filter tank is bent.

[0016] In a preferred embodiment, the generating unit includes an installation cylinder, a docking seat, a fixing cover, a generating cylinder, a gas distribution valve, a ventilation valve, and a humidifying box.

[0026] The present invention adopts the design of a monitoring part. By setting the feedback ball in a hollow shape, the overall mass of the feedback ball can be effectively reduced, enabling the feedback ball to be easily carried by the air flow. At the same time, the gap between the feedback ball and the exhaust pipe can also enhance the acting force of the air flow on the feedback ball, further causing the movement of the feedback ball; the frequency and height of the up and down movement of the feedback ball can be effectively combined with the frequency and intensity during the patient's breathing. Therefore, the frequency and intensity data during the patient's breathing can be obtained in real time by monitoring the movement of the feedback ball. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] To make the above objects, features, and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention with reference to the accompanying drawings of the specification.

[0040] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0041] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present invention. The phrase "in a preferred implementation manner" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that excludes other embodiments.

[0042] Furthermore, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure will be enlarged locally out of the general proportion, and the schematic diagrams are only examples and should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0043] Please refer to Figures 1 to 10 As shown, the present invention provides a real-time monitoring device for respiratory assistance in thoracic surgery nursing, including an installation housing 1. Inside the installation housing 1, there is an extraction part 2, and the extraction part 2 can filter and extract air for pressurized delivery;

[0044] Inside the installation housing 1, there is also a generation part 3, and the generation part 3 can separate oxygen from the air to provide oxygen for the patient;

[0045] Outside the installation housing 1, there is a monitoring part 4. Through the monitoring part 4, the oxygen concentration inside the generation part 3 can be detected, and the generation chambers inside the generation part 3 can be switched for continuous oxygen supply, and the breathing frequency of the patient can also be monitored;

[0046] The monitoring unit 4 includes a monitoring panel 401, a face mask 402, an exhaust pipe 403, a feedback ball 404, a position sensor 405, and an oxygen sensor 406. The monitoring panel 401 is fixedly connected to the outside of the installation housing 1. The input end of the face mask 402 is communicated with the generating unit 3. The input end of the exhaust pipe 403 is communicated with the output end of the face mask 402. The feedback ball 404 is arranged inside the exhaust pipe 403, and the feedback ball 404 is matched with the input end of the exhaust pipe 403. The position sensor 405 is arranged inside the installation housing 1, and the monitoring surface of the position sensor 405 is matched with the inside of the exhaust pipe 403. The oxygen sensor 406 is arranged inside the face mask 402.

[0047] Specifically, by starting the compression pump 203, the air inside the secondary filter tank 202 and the primary filter cover 201 is extracted and pressurized.

[0048] Then the pressurized air enters the inside of the generating cylinder 304 through the air distribution valve 305. Inside the generating cylinder 304, the pressurized air preferentially adsorbs nitrogen and a small amount of other gases through the microporous structure of the zeolite molecular sieve. Oxygen and argon are not adsorbed because their molecules are larger or their polarity is weaker, and become a rich oxygen stream output. This is common knowledge and will not be described in detail.

[0049] When the rich oxygen stream discharges the high-concentration oxygen inside the generating cylinder 304 through the air exchange valve 306 inside the face mask 402, the oxygen sensor 406 inside the face mask 402 monitors the oxygen concentration inside the face mask 402, and then the face mask 402 is fixed at the patient's mouth and nose, enabling the patient to breathe higher-concentration oxygen.

[0050] During the patient's breathing, the airflow inside the face mask 402 changes, causing the air pressure inside the face mask 402 to increase when the patient exhales. During the process of discharging the high-pressure gas inside the exhaust pipe 403, the high-pressure airflow can push the feedback ball 404 upward.

[0051] When the patient inhales, the feedback ball 404 inside the exhaust pipe 403 moves downward under the influence of gravity and the inhalation airflow.

[0052] The position sensor 405 monitors the frequency and distance of the up and down movement of the feedback ball 404 through the inside of the exhaust pipe 403, and sends the monitored data to the inside of the monitoring panel 401 for analysis and processing, so as to judge the patient's breathing intensity in real time.

[0053] Please refer to Figures 1 to 3As shown, the monitoring panel 401 is connected to the mains power supply. The monitoring panel 401 is electrically connected to the position sensor 405, the oxygen sensor 406, the compression pump 203, the gas distribution valve 305, and the ventilation valve 306. A microcomputer is integrated inside the monitoring panel 401. The position data of the feedback ball 404 inside the exhaust pipe 403 is monitored in real time by the position sensor 405 and sent to the inside of the monitoring panel 401 to analyze the patient's breathing intensity and frequency.

[0054] The oxygen content data inside the mask 402 is monitored by the oxygen sensor 406 and sent to the inside of the monitoring panel 401 for processing. The monitoring panel 401 adjusts the size of the output end of the ventilation valve 306 according to the concentration of the oxygen sensor 406 to adjust the oxygen content inside the mask 402.

[0055] At the same time, when it is necessary to switch the reaction chamber inside the reaction cylinder 304, the monitoring panel 401 switches the reaction chambers connected by the corresponding gas distribution valve 305 and ventilation valve 306 to achieve the switching of different reaction chambers and ensure the continuous supply of oxygen inside the reaction cylinder 304.

[0056] Please refer to Figure 2 、 Figure 4 and Figure 5 As shown, the output end of the exhaust pipe 403 is set to be bent. The bent shape enables the output end of the exhaust pipe 403 to output downward during exhaust, thereby preventing dust in the external gas from falling into the inside of the exhaust pipe 403.

[0057] Please refer to Figure 6 As shown, the inside of the feedback ball 404 is set to be hollow, and there is a gap between the diameter of the feedback ball 404 and the inner diameter of the exhaust pipe 403. The hollow setting of the feedback ball 404 can effectively reduce the overall mass of the feedback ball 404, enabling the feedback ball 404 to be easily carried by the airflow. At the same time, the gap between the feedback ball 404 and the exhaust pipe 403 can also enhance the acting force of the airflow on the feedback ball 404, further causing the movement of the feedback ball 404.

[0058] The frequency and height of the up and down movement of the feedback ball 404 can be effectively combined with the frequency and intensity during the patient's breathing. Therefore, the frequency and intensity data during the patient's breathing can be obtained in real time by monitoring the movement of the feedback ball 404.

[0059] Please refer to Figure 7As shown in the figure, the extraction unit 2 includes a primary filter cover 201, a secondary filter tank 202, a compression pump 203, a bearing platform 204, an elastic support member 205, and a sound insulation cover 206. The primary filter cover 201 is fixedly connected to the inside of the installation housing 1, the secondary filter tank 202 is fixedly connected to the inside of the installation housing 1, the input end of the secondary filter tank 202 is communicated with the inside of the primary filter cover 201, the input end of the compression pump 203 is connected to the output end of the secondary filter tank 202, the upper end of the bearing platform 204 is fixedly connected to the lower end of the compression pump 203, the upper end of the elastic support member 205 is fixedly connected to the lower end of the bearing platform 204, the lower end of the elastic support member 205 is fixedly connected to the inside of the installation housing 1, the sound insulation cover 206 is arranged inside the installation housing 1, and the inside of the sound insulation cover 206 cooperates with the compression pump 203;

[0060] Start the compression pump 203 to extract the air inside the secondary filter tank 202 and the primary filter cover 201, so that the external air first passes through the first filtration of the primary filter cover 201 to remove large particulate matter in the air, and then the air passes through the inside of the secondary filter tank 202 for secondary filtration to further remove particulate matter in the air, and the air purity inside the compression pump 203 is ensured through two-stage filtration;

[0061] During the operation of the compression pump 203, the vibration generated during the operation of the compression pump 203 is absorbed by the elastic support member 205. The elastic support member 205 deforms when subjected to the acting force during the operation of the compression pump 203 by using its elastic characteristics to absorb and buffer the mechanical vibration of the compression pump 203, thereby reducing the vibration transmitted to the installation housing 1, effectively reducing the impact of vibration on the equipment, and improving the stability and reliability of the equipment.

[0062] Please refer to Figure 5 As shown in the figure, sound-absorbing cotton is arranged inside the sound insulation cover 206. Through the arrangement of the sound insulation cover 206 and the sound-absorbing cotton, the sound waves generated during the operation of the compression pump 203 can be absorbed, and the reflection and propagation of the sound waves can be reduced, thereby effectively reducing the noise level inside and outside the sound insulation cover 206. This ensures that the noise generated during the operation of the equipment will not have too much impact on the surrounding environment;

[0063] At the same time, the sound-absorbing cotton can effectively reduce the sound waves brought by these resonances through its soft material, make the noise more stable, and further reduce the impact of the noise on the operator and the surrounding environment, thereby improving safety and comfort.

[0064] Please refer to Figure 8 As shown in the figure, the internal gas flow of the secondary filter tank 202 is in a bent shape. The bent air flow path can increase the contact time between the air and the secondary filter tank 202, so that the microparticles and pollutants in the air have a longer time to collide and adhere to the filter material inside the secondary filter tank 202, thereby improving the filtration efficiency.

[0065] Please refer to Figure 7 As shown, the generating part 3 includes an installation cylinder 301, a docking seat 302, a fixing cover 303, a generating cylinder 304, a gas distribution valve 305, a ventilation valve 306 and a humidifying box 307. The installation cylinder 301 is fixedly connected to the inside of the installation housing 1. The docking seat 302 is fixedly arranged at the lower end inside the installation cylinder 301. The fixing cover 303 is assembled at the upper end of the installation cylinder 301. The generating cylinder 304 is arranged inside the installation cylinder 301. An adsorption material is arranged inside the generating cylinder 304. The adsorption material inside the generating cylinder 304 is zeolite molecular sieve. The input end of the gas distribution valve 305 is matched with the output end of the compression pump 203. The output end of the gas distribution valve 305 is communicated with the inside of the generating cylinder 304 through the inside of the fixing cover 303. The input end of the ventilation valve 306 is communicated with the inside of the docking seat 302. The ventilation valve 306 is provided with two output ends. One of the output ends of the ventilation valve 306 is connected to the external air. The humidifying box 307 is assembled inside the installation housing 1. The other output end of the ventilation valve 306 is communicated with the inside of the humidifying box 307. The inside of the humidifying box 307 is communicated with the input end of the face mask 402;

[0066] When the generating cylinder 304 needs to be maintained and replaced, only need to unscrew the fixing bolt at the fixing cover 303, then pull up the fixing cover 303 and turn it to open the fixing cover 303. Then the generating cylinder 304 can be pulled out from the inside of the installation cylinder 301. Then insert the new generating cylinder 304 into the inside of the installation cylinder 301, so that the lower end of the generating cylinder 304 is inserted into the inside of the docking seat 302 to realize the docking of the generating cylinder 304 and the docking seat 302. After replacing the new generating cylinder 304, turn the fixing cover 303 to close it and insert it into the upper end of the generating cylinder 304. Then apply an extrusion force to the fixing cover 303 in the direction of the generating cylinder 304 by tightening the bolt to fix the fixing cover 303 at the upper end of the generating cylinder 304. Thus, the convenient replacement of the generating cylinder 304 is realized;

[0067] After the generating cylinder 304 is installed between the fixing cover 303 and the docking seat 302, during the process of oxygen generation, the high-pressure air of the compression pump 203 is controlled by the gas distribution valve 305 to be input into the inside of the generating cylinder 304. After the high-pressure air enters the inside of the generating cylinder 304, nitrogen and a small amount of other gases are preferentially adsorbed through the microporous structure of the zeolite molecular sieve. However, oxygen and argon are not adsorbed because their molecules are larger or their polarity is weaker, and become a rich oxygen stream output. This is common knowledge and will not be specifically described;

[0068] After the oxygen content inside the reaction cylinder 304 increases, the air with a high oxygen content is first discharged into the interior of the humidifying box 307 by opening the ventilation valve 306. The interior of the humidifying box 307 is filled with a humidifying liquid. The air with a high oxygen content increases its moisture content after passing through the humidifying liquid, preventing the highly oxygenated air from being overly dry, alleviating the irritation caused by the manufactured oxygen to the patient's respiratory tract, and avoiding symptoms such as discomfort, coughing, or throat discomfort. Humidification can help keep the patient's respiratory tract moist, reduce discomfort. At the same time, the appropriate humidity in the oxygen can help maintain the normal functions of the patient's lungs and airways, promote the normal movement of the mucosa, facilitate the discharge of secretions, and reduce the risk of infection and inflammation.

[0069] Please refer to Figure 9 and Figure 10 As shown, at least two reaction chambers are provided inside the reaction cylinder 304. Each reaction chamber is provided with a corresponding gas distribution valve 305 and a ventilation valve 306. During the operation of one of the reaction chambers inside the reaction cylinder 304, the gas distribution valve 305 is opened to introduce the high-pressure air from the compression pump 203 into the interior of the reaction chamber for nitrogen adsorption. When the zeolite molecular sieve is approaching saturation, the gas distribution valve 305 of one of the reaction chambers reduces the input of high-pressure air, and the ventilation valve 306 closes the pipeline connected to the face mask 402 and opens the output end communicating with the outside, so that the interior of the reaction chamber is connected to the external environment and returns to the normal pressure state, enabling the zeolite molecular sieve inside the reaction chamber to gradually release the adsorbed nitrogen, allowing the high-concentration nitrogen to be discharged into the external environment along with the air flow until the zeolite molecular sieve returns to the state before adsorption. At this time, the ventilation valve 306 closes the channel connecting the reaction chamber to the outside, and the corresponding reaction chamber is in a closed state until the zeolite molecular sieve of another reaction chamber is saturated and needs to be switched to this reaction chamber. The gas distribution valve 305 injects high-pressure air into the interior of this reaction chamber to generate an oxygen-rich air flow using the zeolite molecular sieve, and the ventilation valve 306 opens the channel communicating with the face mask 402, so that the oxygen-rich air flow is discharged into the face mask 402 for oxygen supply;

[0070] Through the coordination between the gas distribution valves 305 and the ventilation valves 306 of multiple reaction chambers, the adsorption and desorption of nitrogen by the zeolite molecular sieve inside different reaction chambers can be carried out separately, realizing the continuous supply of oxygen by the device.

[0071] A real-time monitoring method for respiratory assistance in thoracic surgery nursing, applied to a real-time monitoring device for respiratory assistance in thoracic surgery nursing, includes the following steps:

[0072] Step 1: Start the compression pump 203 to extract the air inside the secondary filter tank 202 and the primary filter cover 201 and pressurize the air;

[0073] Step 2: The pressurized air enters the interior of the generating cylinder 304 through the air distribution valve 305. The interior of the generating cylinder 304 adsorbs nitrogen in the pressurized air, increasing the oxygen concentration in the air.

[0074] Step 3: Fix the mask 402 at the patient's mouth and nose, and discharge the high-concentration oxygen inside the generating cylinder 304 through the air exchange valve 306 for the patient to breathe at the mask 402.

[0075] Step 4: The gas inside the mask 402 is discharged through the interior of the exhaust pipe 403. When the patient breathes, the airflow inside the mask 402 changes. When the patient exhales, the feedback ball 404 inside the exhaust pipe 403 moves upward along with the airflow when the gas is discharged. When the patient inhales, the feedback ball 404 inside the exhaust pipe 403 moves downward along with the airflow when the gas is recycled.

[0076] The working principle of the present invention is: By starting the compression pump 203, the air inside the secondary filter tank 202 and the primary filter cover 201 is extracted and pressurized.

[0077] Then the pressurized air enters the interior of the generating cylinder 304 through the air distribution valve 305. Inside the generating cylinder 304, the pressurized air preferentially adsorbs nitrogen and a small amount of other gases through the microporous structure of the zeolite molecular sieve, while oxygen and argon are not adsorbed because their molecules are larger or their polarity is weaker, and become a rich oxygen stream output.

[0078] When the rich oxygen stream discharges the high-concentration oxygen inside the generating cylinder 304 into the interior of the mask 402 through the air exchange valve 306, the oxygen sensor 406 inside the mask 402 monitors the oxygen concentration inside the mask 402, and then fixes the mask 402 at the patient's mouth and nose so that the patient can breathe higher-concentration oxygen.

[0079] When the patient breathes, the airflow inside the mask 402 changes, causing the air pressure inside the mask 402 to increase when the patient exhales. During the process of discharging the high-pressure gas inside the exhaust pipe 403, the high-pressure airflow can push the feedback ball 404 upward.

[0080] When the patient inhales, the feedback ball 404 inside the exhaust pipe 403 moves downward under the influence of gravity and the inhalation airflow.

[0081] The position sensor 405 monitors the frequency and distance of the up and down movement of the feedback ball 404 through the interior of the exhaust pipe 403, and sends the monitored data to the interior of the monitoring panel 401 for analysis and processing, so as to judge the patient's breathing intensity in real time.

[0082] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention. The structures, devices, and operation methods not specifically described and explained in the present invention are implemented by conventional means in the art without special description and limitation.
