Abstract
Description
Technical Field
[0001] This invention relates to the field of ventilator mask technology, specifically to a non-invasive ventilator mask auxiliary fixation device. Background Technology
[0002] In clinical practice, patients who need to receive oxygen via face mask are usually in emergency situations or other situations requiring a high concentration of oxygen. Common oxygen masks are mainly used for patients with symptoms of difficulty breathing, such as severe hypoxemia, altitude sickness, respiratory failure, chronic obstructive pulmonary disease, and acute respiratory distress syndrome. High concentrations of oxygen help to rapidly increase the patient's blood oxygen saturation, thereby improving tissue hypoxia and circulatory function.
[0003] In respiratory therapy, medical devices used to implement continuous positive airway pressure ventilation typically consist of a pressure pump, a smart gas supply chip, and a mask assembly that connects to the patient. Currently used masks are mostly made of silicone, which has good sealing and comfort, but need to be replaced regularly to ensure their performance and hygiene.
[0004] In actual use, the mask is prone to displacement due to insecure fixation, which can lead to air leakage. Air leakage not only reduces the treatment effect but may also increase the patient's breathing resistance, affecting their normal breathing and thus adversely affecting the overall treatment effect. Therefore, we propose a non-invasive ventilator mask auxiliary fixation device. Summary of the Invention
[0005] The purpose of this invention is to provide a non-invasive ventilator mask auxiliary fixation device to solve the problem that the mask is prone to displacement due to insecure fixation, resulting in air leakage. Air leakage not only reduces the treatment effect, but may also increase the patient's breathing resistance, affecting their normal breathing, and thus adversely affecting the overall treatment effect.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a non-invasive ventilator mask auxiliary fixing device, comprising: a body, an air supply tube and a mask, one end of the air supply tube is connected to the body and is used to deliver oxygen, the mask is connected to the other end of the air supply tube and is worn on the patient's face to form a closed airway space, and a fixing rope is connected to the mask for fixing the mask.
[0007] Also includes:
[0008] The judgment component is connected to the mask. During patient treatment, the judgment component is used to monitor whether the mask is sealed and to determine whether the gas delivery tube is blocked.
[0009] An adjustment component is attached to the mask and connected to a fixing rope. The adjustment component is used to adjust the tension of the fixing rope.
[0010] The alarm component is connected to the machine body and the gas supply tube. When the gas supply tube is blocked, the alarm component is used to remind medical staff to replace the gas supply tube.
[0011] The judgment component includes a compression bladder, which is connected to the mask and fits in close contact with the patient's face. A connecting tube is connected to the compression bladder, and a detection device is connected to the connecting tube. The detection device is used to monitor whether the mask is leaking.
[0012] The testing component includes a gas storage box, which is connected to the other end of the connecting pipe, and a sliding plate is provided inside the gas storage box.
[0013] The sliding plate is connected to a pressure plate, and the gas storage box is connected to a trigger switch.
[0014] The gas storage box has through holes.
[0015] The adjustment component includes a protective frame mounted on the face mask and connected to a fixing rope. An adjustment element is connected to the protective frame to adjust the length of the fixing rope.
[0016] The adjusting component includes a motor, which is connected to the protective cover. A rotating shaft is connected to the output shaft of the motor, and the rotating shaft is connected to a fixed rope. A snap-fit component is connected to the protective frame.
[0017] The snap-fit component includes snap-fit posts, and the face mask is connected to fixing holes, with the snap-fit posts corresponding to the fixing holes.
[0018] The snap-fit posts are made of silicone.

[0020] The present invention has at least the following beneficial effects: by setting a judgment component, an adjustment component and an alarm component, the judgment component is connected to the mask. When the patient is treated, the judgment component is used to monitor whether the mask is sealed and to determine whether the air supply tube is blocked. During use, the mask sealing status can be monitored in real time to prevent oxygen leakage and prevent the mask from leaking air, which would reduce the treatment effect and increase the patient's breathing resistance.
[0021] The adjustment component is connected to the mask and to the fixing rope. The adjustment component is used to adjust the tension of the fixing rope. When it is determined that there is a leak in the mask, the adjustment component is activated to adjust the tension of the fixing rope so that the mask fits the patient's face.
[0022] The alarm component is connected to the body and the air supply tube. When the air supply tube is blocked, the alarm component is used to remind medical staff to replace the air supply tube. When the adjustment component has adjusted the mask to fit the patient, the alarm component still monitors the damping force inside the mask. When the damping force exceeds the threshold, the alarm component is activated. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0034] Example 1
[0035] Please see Figures 1 to 9 The present invention provides a technical solution: a non-invasive ventilator mask auxiliary fixing device, comprising: a body 1, an air supply tube 2 and a mask 3. One end of the air supply tube 2 is connected to the body 1 and is used to deliver oxygen. The mask 3 is connected to the other end of the air supply tube 2 and is used to deliver oxygen from the body 1 to the patient. The mask 3 is worn on the patient's face to form a closed airway space, thereby ensuring that oxygen can be effectively delivered to the patient's body. A fixing rope 4 is connected to the mask 3 and is used to fix the mask 3 securely to the patient's face to prevent it from falling off or leaking during use.
[0036] Also includes:
[0037] The judgment component 6 is connected to the mask 3. When the patient is being treated, the judgment component 6 is used to monitor whether the mask 3 is sealed and to determine whether the air supply tube 2 is blocked. During use, it can realize real-time monitoring of the sealing status of the mask 3 to prevent oxygen leakage and prevent the mask 3 from leaking air, which would reduce the treatment effect and increase the patient's breathing resistance.
[0038] Adjustment component 7 is connected to mask 3 and is also connected to fixing rope 4. Adjustment component 7 is used to adjust the tension of fixing rope 4. When judgment component 6 determines that mask 3 is leaking, it activates adjustment component 7 to adjust the tension of fixing rope 4 so that mask 3 fits the patient's face.
[0039] Alarm component 5 is connected to the body 1 and the air supply tube 2. When the air supply tube 2 is blocked, the alarm component 5 is used to remind medical staff to replace the air supply tube 2. When the adjustment component 7 has adjusted the mask 3 to fit the patient, the alarm component 5 still monitors the damping force inside the mask 3 and activates when it exceeds the threshold.
[0040] The judgment component 6 includes a squeezing bladder 9, which is connected to the mask 3 and fits in close contact with the patient's face. A connecting tube 15 is connected to the squeezing bladder 9, and a detection element 18 is connected to the connecting tube 15. The detection element 18 is used to monitor whether the mask 3 is leaking. The squeezing bladder 9 is located in the area where the mask 3 fits in close contact with the patient's face, and is made of flexible medical silicone, which has good elasticity and fit.
[0041] The detection component 18 includes an air storage box 61, which is connected to the other end of the connecting pipe 15. A sliding plate 17 is provided inside the air storage box 61. The air storage box 61 is used to receive the air pressure changes caused by the compression bag 9 due to the patient's facial movements. When the compression bag 9 is in a sealed state with the patient's face, the sliding plate 17 slides inside the air storage box 61.
[0042] A pressure plate 19 is connected inside the sliding plate 17, and a trigger switch 20 is connected inside the gas storage box 61. When the patient wears the mask 3, the compression bag 9 is in close contact with the face. When the patient breathes or moves their face, the compression bag 9 will be squeezed or released, causing the gas inside to enter the gas storage box 61 through the connecting pipe 15, thereby pushing the sliding plate 17 to move. If the mask 3 is well sealed, the displacement of the sliding plate 17 is within the normal range, and the trigger switch 20 will not be triggered. If the mask 3 leaks, the air pressure inside the compression bag 9 changes abnormally, and the displacement of the sliding plate 17 exceeds the set threshold, the trigger switch 20 will be triggered, and the system will determine that the mask 3 is not well sealed. This allows for real-time monitoring of the sealing status of the mask 3, preventing oxygen leakage, avoiding insufficient oxygen supply due to poor sealing, and improving the treatment effect. A through hole 16 is provided on the gas storage box 61 to balance the air pressure and prevent accidental triggering.
[0043] The adjustment component 7 includes a protective frame 10, which is mounted on the face mask 3. The protective frame 10 is used to support the adjustment component and is connected to the fixing rope 4. The adjustment component is connected to the protective frame 10 and is used to adjust the length of the fixing rope 4.
[0044] The adjustment component includes a motor 12 connected to the protective cover. A rotating shaft 13 is connected to the output shaft of the motor 12, and the rotating shaft 13 is connected to the fixing rope 4. A snap-fit component 11 is connected to the protective frame 10. When the judgment component 6 detects a leak in the mask 3, the trigger switch 20 starts the motor 12. The motor 12 drives the rotating shaft 13 to rotate forward, which in turn tightens the fixing rope 4, thereby adjusting the fit between the mask 3 and the patient's face to compress the compression bladder 9. When the mask 3 is sealed again, the pressure plate 19 disengages from the trigger switch 20, thereby turning off the motor 12. The adjustment process achieves automatic closed-loop control to ensure that the mask 3 is always in the best sealing state.
[0045] The snap-fit component 11 includes a snap-fit post 14. The face mask 3 has a fixing hole, and the snap-fit post 14 corresponds to the fixing hole. The protective frame 10 can be disassembled and installed by setting the snap-fit post 14. When it is necessary to disassemble or replace the fixing rope 4, the disassembly and assembly are simple and quick, without the need for tools. Simply pull the snap-fit post 14 out of the fixing hole to complete the disassembly. Then the fixing rope 4 can be disassembled and installed, which is convenient for disinfecting the fixing rope 4. The fixing rope 4 can be reused, saving costs. The snap-fit post 14 is made of silicone material, which has good elasticity, is easy to insert and remove, and is not easy to break. It still maintains good connection performance after multiple insertions and removals. It is suitable for medical environments, avoids irritation to the patient's skin, improves connection stability, and prevents it from falling off during use.
[0046] Example 2
[0047] The alarm component 5 includes a flow monitor 51, which is connected to the gas supply pipe 2. The flow monitor 51 is used to monitor the gas flow rate. An alarm 8 is connected to the body 1. If the flow monitor 51 still detects an abnormal flow rate after the fixing rope 4 is adjusted and the mask 3 is in a sealed state, the alarm 8 will be activated to remind medical staff to treat the patient in a timely manner.
