Description

Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a training device for respiratory and critical care medicine. Background Technology

[0002] Patients undergoing cardiac surgery and critical care often require respiratory training during the recovery phase. The main purpose is to expand the lungs, prevent postoperative atelectasis, increase lung ventilation, increase tidal volume, reduce postoperative wound pain caused by breathing problems, and promote oxygen supply and systemic diffusion, thus facilitating rapid lung recovery. The inventors have observed that while some adults can follow medical staff's instructions for respiratory training after surgery, some children, due to postoperative wound pain, are unwilling to follow instructions. Even if they can follow instructions, the repetitive nature of the training often leads children to abandon it after one or two sessions, hindering subsequent recovery. Therefore, this invention addresses these issues by proposing a respiratory and critical care medical training device. Summary of the Invention

[0003] The purpose of this invention is to provide a training device for respiratory and critical care medicine to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] As an alternative embodiment of the respiratory and critical care medicine training device described in this invention, the respiratory and critical care medicine training device includes a saliva treatment module.

[0006] One side of the saliva treatment module is spirally connected to an entertainment module for children's breathing training. The other end of the entertainment module is connected to a first hose. The other end of the first hose is connected to an airflow detection module for detecting exhaust quality during children's breathing training. The other end of the airflow detection module is connected to a second hose. The other end of the second hose is connected to a disinfection module for gas disinfection.

[0007] The entertainment module includes a hollow tube with a hollow structure. One end of the hollow tube is spirally connected to the saliva treatment module, and the other end of the hollow tube is connected to the first flexible tube. A transparent tube made of transparent glass plate is also installed inside the hollow tube.

[0008] An annular groove is provided on the outer side of the hollow tube, and an embedded first magnetic ring is installed in the annular groove. The hollow tube is slidably connected to a rotating ring through the annular groove, and three sets of evenly distributed second magnetic rings are installed inside the rotating ring.

[0009] The outer side of the rotating ring is connected to a first hollow sleeve, a second hollow sleeve, and a third hollow sleeve. A connecting rope is fixedly connected to the inner wall of the first hollow sleeve, and a floating ball is fixedly connected to the other end of the connecting rope. A balloon is installed at the other end of the second hollow sleeve, and a moving ball is set inside the third hollow sleeve.

[0010] As an alternative embodiment of the respiratory and critical care medicine training device described in this invention, the third hollow sleeve is made of transparent acrylic sheet, and an exhaust hole is provided at one end of the third hollow sleeve.

[0011] Patients undergoing critical cardiac surgery often require breathing exercises during the recovery phase. The main purpose is to expand the lungs, prevent postoperative atelectasis, increase lung ventilation, increase tidal volume, reduce postoperative wound pain caused by breathing difficulties, and promote oxygen supply and systemic diffusion, thus facilitating rapid lung recovery. The inventors have observed that while some adults can follow medical staff's instructions for breathing exercises after surgery, some children, due to postoperative wound pain, are unable to follow instructions at all. Even those who can follow instructions often find the breathing exercises too simple. First, children often become unwilling to continue breathing exercises after completing one or two sessions, which is detrimental to subsequent rehabilitation. When conducting breathing exercises for pediatric patients, the second magnetic ring on the inner side of the rotating ring works in conjunction with the first magnetic ring for connection. By rotating the outer rotating ring, the second magnetic ring in different positions can be switched to work with it. The arrangement of the first, second, and third hollow sleeves allows different entertainment tools to be placed on top. When the child blows on the saliva treatment module, the entertainment toys on top of the entertainment module are activated, which helps to attract children to perform multiple breathing exercises, effectively exercising the lungs and facilitating subsequent rehabilitation.

[0012] As an optional embodiment of the respiratory and critical care medical training device described in this invention, the saliva treatment module includes a connecting pipe that is spirally connected to the entertainment module on one side, and an air nozzle is fixedly connected to the other end of the connecting pipe. Two sets of filter screens are installed inside the air nozzle, and a collection frame for collecting saliva is also installed at the bottom of the air nozzle.

[0013] Children often drool when blowing air. In this case, two sets of filters are installed inside the mouthpiece, and the two sets of filters are connected one above the other inside the mouthpiece. The airflow channel is set in a maze. At the same time, the filter uses a mesh plate to help capture saliva. The mouthpiece below the filter is funnel-shaped, which makes it easy for saliva to collect and concentrate in the collection box for convenient saliva treatment.

[0014] As an optional embodiment of the respiratory and critical care medicine training device described in this invention, the airflow detection module includes a detection sleeve connected to a first flexible tube. Multiple warning lights are installed on the outer side of the detection sleeve. The other end of the detection sleeve is connected to a second flexible tube. An installation ring is fixedly connected inside the detection sleeve. An adaptive connection mechanism is installed inside the installation ring. A guide cylinder is provided on one side of the adaptive connection mechanism. A contact switch is also installed inside the guide cylinder. A breathable mesh plate is fixedly connected to the outer side of the contact switch. The outer side of the breathable mesh plate is fixedly connected to the detection sleeve. A timer is also fixedly connected inside the detection sleeve.

[0015] As an optional embodiment of the training device for respiratory and critical care medicine described in this invention, the adaptive connection mechanism includes a mounting cylinder fixedly connected to a mounting ring, with evenly distributed ventilation holes on the outer side of the mounting cylinder, a sliding plate slidably connected inside the mounting cylinder, a connecting rod fixedly connected to the other end of the sliding plate, and a compression ball fixedly connected to the other end of the connecting rod.

[0016] As an alternative embodiment of the training device for respiratory and critical care medicine described in this invention, a spring is further provided on the outer side of the connecting rod, one end of the spring is fixedly connected to the sliding plate, and the other end of the spring is fixedly connected to the mounting cylinder.

[0017] When children are doing breathing exercises, the duration of their exhalation is also important. The gas continuously blows the adaptive connection mechanism, one side of which contacts the contact switch. After a certain period of time, the delay timer controls the warning light to light up. This can attract children and increase the fun, and it can also let them know whether the volume and quality of the exhaled air meet the standards.

[0018] As an optional embodiment of the training device for respiratory and critical care medicine described in this invention, the disinfection module includes a disinfection frame connected to a second flexible tube, a peristaltic pump installed inside the disinfection frame, an input tube connected to the input end of the peristaltic pump, one side of the input tube connected to the second flexible tube, and an output tube connected to the output end of the peristaltic pump.

[0019] The disinfection frame has a partition plate inside that divides it into two chambers. A disinfection heating net is fixedly connected to the outside of the partition plate, and the other end of the disinfection heating net is fixedly connected to the disinfection frame.

[0020] When children are doing breathing exercises, the gas enters the second tube. The peristaltic pump is activated to actively extract the gas, preventing the pressure inside the second tube from increasing and making it inconvenient for children to do breathing exercises. The gas passes through the disinfectant and disinfection heating net on one side of the partition plate, which can effectively disinfect the gas and ensure the quality of the exhaust air.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] When conducting breathing training for pediatric patients, the second magnetic ring on the inner side of the rotating ring cooperates with the first magnetic ring for connection. By rotating the outer rotating ring, the second magnetic ring in different positions can be switched to cooperate with it. The arrangement of the first hollow sleeve, the second hollow sleeve, and the third hollow sleeve allows different entertainment tools to be placed on top. When the child blows on the saliva treatment module, the entertainment toys on the top of the entertainment module are activated, which helps to attract the child to perform multiple breathing training sessions, helps to effectively exercise the lungs, and is beneficial to subsequent rehabilitation work.

[0023] Children often drool when blowing air. In this case, two sets of filters are installed inside the mouthpiece, and the two sets of filters are connected one above the other inside the mouthpiece. The airflow channel is set in a maze. The filter is made of mesh plate, which helps to capture saliva. The mouthpiece below the filter is funnel-shaped, which makes it easy for saliva to collect and concentrate in the collection box for easy centralized treatment.

[0024] When children are doing breathing training, the duration of their exhalation is also important. The gas continuously blows the adaptive connection mechanism, one side of which contacts the contact switch. After a certain period of time, the delay timer controls the warning light to light up. This can attract children and increase the fun, and it can also let them know whether the volume and quality of the exhaled air are up to standard.

[0025] When children are doing breathing exercises, the gas enters the second tube. The peristaltic pump is activated to actively extract the gas, preventing the pressure inside the second tube from increasing and making it inconvenient for children to do breathing exercises. The gas passes through the disinfectant and disinfection heating net on one side of the partition plate, which can effectively disinfect the gas and ensure the quality of the exhaust air.

Detailed Implementation

[0035] Example 1: Please refer to Figure 1 , Figure 3 , Figure 4 and Figure 5 The present invention provides a technical solution:

[0036] A training device for respiratory and critical care medicine, including a saliva treatment module 1;

[0037] One side of the saliva treatment module 1 is spirally connected to an entertainment module 2 for children’s breathing training. The other end of the entertainment module 2 is connected to a first hose 3. The other end of the first hose 3 is connected to an airflow detection module 4 for children’s breathing training to detect exhaust quality. The other end of the airflow detection module 4 is connected to a second hose 5. The other end of the second hose 5 is connected to a disinfection module 6 for gas disinfection.

[0038] The entertainment module 2 includes a hollow tube 201, one end of which is spirally connected to the saliva treatment module 1, and the other end of which is connected to the first flexible tube 3. A transparent tube 202 made of transparent glass plate is also installed inside the hollow tube 201.

[0039] The hollow tube 201 has an annular groove on its outer side, and an embedded first magnetic ring 204 is installed in the annular groove. The hollow tube 201 is slidably connected to a rotating ring 203 through the annular groove. Three sets of evenly distributed second magnetic rings 205 are installed inside the rotating ring 203.

[0040] The outer side of the rotating ring 203 is connected to a first hollow sleeve 206, a second hollow sleeve 209 and a third hollow sleeve 211. A connecting rope 207 is fixedly connected to the inner wall of the first hollow sleeve 206. A floating ball 208 is fixedly connected to the other end of the connecting rope 207. A balloon 210 is installed at the other end of the second hollow sleeve 209. A moving ball 212 is set inside the third hollow sleeve 211.

[0041] The third hollow sleeve 211 is made of transparent acrylic sheet, and an exhaust hole is also provided at one end of the third hollow sleeve 211.

[0042] Patients undergoing critical cardiac surgery often require breathing exercises during the recovery phase. The main purpose is to expand the lungs, prevent postoperative atelectasis, increase lung ventilation, increase tidal volume, reduce postoperative wound pain caused by breathing difficulties, and promote oxygen supply and systemic diffusion, thus facilitating rapid lung recovery. The inventors have observed that while some adults can follow medical staff's instructions for breathing exercises after surgery, some children, due to postoperative wound pain, are completely unable to follow instructions. Even those who can follow instructions often struggle due to the repetitive nature of the exercises, frequently failing to complete even one or two sessions. After the initial training, the child becomes unwilling to continue breathing exercises, which is detrimental to subsequent rehabilitation. When conducting breathing exercises for pediatric patients, the second magnetic ring 205 on the inner side of the rotating ring 203 cooperates with the first magnetic ring 204 for connection. By rotating the outer rotating ring 203, the second magnetic ring 205 in different positions can be switched to cooperate with it. The arrangement of the first hollow sleeve 206, the second hollow sleeve 209, and the third hollow sleeve 211 allows different entertainment tools to be placed on top. When the child blows on the saliva treatment module 1, the entertainment toy on the entertainment module 2 is activated, which helps to attract the child to perform multiple breathing exercises, helps the lungs to be effectively exercised, and is beneficial to subsequent rehabilitation work.

[0043] The specific steps are as follows:

[0044] During postoperative breathing training in children, children do not follow the instructions of medical staff as adults. Therefore, an entertainment module 2 is installed at one end of the saliva treatment module 1. By rotating the rotating ring 203, three entertainment modes can be adjusted:

[0045] Mode 1: The second magnetic ring 205 inside the first hollow sleeve 206 rotates to the outside of the first magnetic ring 204. The opposite end faces of the first magnetic ring 204 and the second magnetic ring 205 are set with opposite poles for mutual attraction. The first hollow sleeve 206 is connected to the inside of the hollow tube 201. When a child blows air into the saliva treatment module 1, the air blows the floating ball 208 above the first hollow sleeve 206, making it float upwards to attract children, increase fun, and prevent it from falling off under the action of the connecting rope 207.

[0046] Mode 2: Continue to rotate the rotating ring 203. The second magnetic ring 205 inside the second hollow sleeve 209 comes into contact with and is attracted to the first magnetic ring 204. At this time, gas enters the balloon 210 through the second hollow sleeve 209, making it inflated to attract children and increase fun.

[0047] Mode 3: Continue to rotate the rotating ring 203. The second magnetic ring 205 inside the third hollow sleeve 211 comes into contact with and is attracted to the first magnetic ring 204. Gas enters the interior of the third hollow sleeve 211, causing the moving ball 212 inside to move, which is used to attract children and increase the fun.

[0048] The third hollow sleeve 211 is made of transparent acrylic sheet, which makes it easy for children to observe the moving ball 212 inside. The vent hole on one side of the third hollow sleeve 211 facilitates the slow discharge of gas, which is used to ensure that the moving ball 212 moves smoothly. The inner side of the moving ball 212 is tightly attached to the inner wall of the third hollow sleeve 211.

[0049] The transparent tube 202 allows observation of the internal water condition and helps determine if saliva has flowed into it, enabling timely disassembly and cleaning.

[0050] Example 2: This example is an improvement upon Example 1. Please refer to [link / reference]. Figure 2 Specifically, the saliva treatment module 1 includes a connecting pipe 101 that is spirally connected to the entertainment module 2 on one side. The other end of the connecting pipe 101 is fixedly connected to an air nozzle 102. Two sets of filter screens 103 are installed inside the air nozzle 102. A collection frame 104 for collecting saliva is also installed at the bottom of the air nozzle 102.

[0051] Children often drool when blowing air. In this case, two sets of filters 103 are installed inside the air mouthpiece 102, and the two sets of filters 103 are connected vertically inside the air mouthpiece 102. The airflow channel is set in a maze. The maze-shaped exhaust channel can ensure smooth airflow. At the same time, the filter 103 is set with a mesh plate, which helps to capture saliva. The air mouthpiece 102 below the filter 103 is funnel-shaped, which makes it easy for saliva to collect and concentrate in the collection frame 104 for convenient centralized treatment of saliva.

[0052] Example 3: This example is an improvement on Example 2. Please refer to [link / reference]. Figure 6 and Figure 7 Specifically, the airflow detection module 4 includes a detection sleeve 401 connected to the first hose 3. Multiple warning lights 402 are installed on the outside of the detection sleeve 401. The other end of the detection sleeve 401 is connected to the second hose 5. An installation ring 403 is fixedly connected inside the detection sleeve 401. An adaptive connection mechanism is installed inside the installation ring 403. A guide cylinder 410 is provided on one side of the adaptive connection mechanism. A contact switch 411 is also installed inside the guide cylinder 410. A breathable mesh plate 412 is fixedly connected to the outside of the contact switch 411. The outside of the breathable mesh plate 412 is fixedly connected to the detection sleeve 401. A delay device 413 is also fixedly connected inside the detection sleeve 401.

[0053] The adaptive connection mechanism includes a mounting cylinder 404 fixedly connected to the mounting ring 403. The outer side of the mounting cylinder 404 is provided with evenly distributed vent holes 405. A sliding plate 406 is slidably connected inside the mounting cylinder 404. A connecting rod 407 is fixedly connected to the other end of the sliding plate 406. A compression ball 408 is fixedly connected to the other end of the connecting rod 407.

[0054] A spring 409 is also provided on the outside of the connecting rod 407. One end of the spring 409 is fixedly connected to the sliding plate 406, and the other end of the spring 409 is fixedly connected to the mounting cylinder 404.

[0055] When children are doing breathing training, the duration of their exhalation is also important. The gas continuously blows the adaptive connection mechanism, one side of which contacts the contact switch 411. After a certain period of time, the delay timer 413 controls the warning light 402 to light up. This can attract children and increase the fun, and it can also let them know whether the volume and quality of the exhaled air meet the standards.

[0056] The specific steps are as follows:

[0057] When a child breathes, gas enters the detection sleeve 401 through the first tubing 3. The detection sleeve 401 then enters the mounting cylinder 404 and compresses the sliding plate 406. The sliding plate 406 slides to one side of the vent 405, and the gas is discharged through the vent 405. The sliding plate 406 also compresses the spring 409, causing the compression ball 408 on one side of the connecting rod 407 to move into the guide cylinder 410. The compression ball 408 contacts the contact switch 411, at which point the delay timer 413 is activated. After a 3-second delay, the warning light 402 is illuminated by the external controller, indicating that the breathing training has been completed. However, if the compression ball 408 separates from the contact switch 411 within 3 seconds, the warning light 402 will not illuminate, indicating that the breathing training has not been completed and further improvements are needed.

[0058] The vent mesh 412 ensures that gas can be smoothly discharged into the second hose 5.

[0059] Example 4: This example is an improvement on Example 3. Please refer to [link / reference]. Figure 8 Specifically, the disinfection module 6 includes a disinfection frame 601 connected to the second hose 5. A peristaltic pump 602 is installed inside the disinfection frame 601. An input pipe 604 is connected to the input end of the peristaltic pump 602. One side of the input pipe 604 is connected to the second hose 5. An output pipe 605 is connected to the output end of the peristaltic pump 602.

[0060] The disinfection frame 601 is equipped with a partition plate 603 that divides the disinfection frame 601 into two chambers. A disinfection heating net 606 is fixedly connected to the outside of the partition plate 603. The other end of the disinfection heating net 606 is fixedly connected to the disinfection frame 601.

[0061] When children are doing breathing training, gas enters the second tubing 5. The peristaltic pump 602 is activated to actively extract the gas, preventing the gas pressure inside the second tubing 5 from increasing and making it inconvenient for children to do breathing training. The gas passes through the disinfectant and the disinfection heating net 606 on one side of the partition plate 603 to effectively disinfect the gas and ensure the quality of the exhaust air.

[0062] The specific steps are as follows:

[0063] When the gas is discharged into the disinfection frame 601, it compresses the disinfectant, creating exhaust pressure. By activating the peristaltic pump 602, the exhaust speed of the peristaltic pump 602 is matched with the child's blowing speed. The airflow detection sensor 7 is used to detect the child's blowing rate, so that the external controller controls the pumping speed of the peristaltic pump 602 to be consistent, ensuring that the gas is smoothly discharged into the disinfectant through the output pipe 605. The air comes into contact with the disinfectant to achieve the disinfection purpose. The appropriate disinfectant can be prepared according to the child's condition. After treatment, the gas moves to the top and then undergoes secondary disinfection through the disinfection heating grid 606 to ensure the quality of the discharged air.

[0064] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only for the purpose of helping to understand the method and core ideas of the present invention. The above descriptions are only preferred embodiments of the present invention. It should be noted that due to the limitations of textual expression, while there are objectively infinite specific structures, those skilled in the art can make several improvements, modifications, or changes without departing from the principles of the present invention, and can also combine the above technical features in an appropriate manner.
