Sputum accumulation can cause respiratory obstruction, pulmonary infection and other complications, which seriously affect the respiratory function and physical health of patients. At present, the main methods for assisting patients to discharge sputum in clinical practice are artificial assisted percussion and mechanical sputum discharge instrument. The artificial assisted percussion operation is more dependent on the experience of medical staff and consumes manpower.

DETAILED DESCRIPTION

[0024] In the following, the present application is further described in conjunction with the drawings and specific embodiments, and it should be noted that the following described embodiments or technical features can be combined in any manner to form new embodiments without conflict.

[0025] It should be noted that when an element is referred to as being "fixed" to another element, it can be directly on the other element or there can be an intervening element. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be an intervening element. The "vertical", "horizontal", "left", "right", and similar expressions used herein are for illustrative purposes only and are not intended to be the only implementation.

[0026] ​​​Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items.

[0027] Referring to Figures 1-4 A breathing valve according to a preferred embodiment of the present application comprises a breathing valve body 1, a filter 2 and a vibration assembly 3. The breathing valve body 1 has an air inlet 11, a valve cavity 12, an air outlet 13 and an exhaust port 14, all of which are in communication with the valve cavity 12. The air inlet 11 is used to connect an air inlet pipe 4, the air outlet 13 is connected with an air guide pipe 5 used to connect with the human body, and the exhaust port 14 is used for the gas in the valve cavity 12 to be discharged to the outside environment. The filter 2 is arranged in the valve cavity 12 and located on the gas conveying path between the air inlet 11 and the air outlet 13. The vibration assembly 3 is installed on the breathing valve body 1 and abuts against the air guide pipe 5, and is used to vibrate the air guide pipe 5.

[0028] In operation, gas flows from the air inlet pipe 4 into the valve cavity 12 of the breathing valve body 1 through the air inlet 11. The valve cavity 12 serves as the core space for gas flow and is connected with the air inlet 11, the air outlet 13 and the exhaust port 14. After entering the valve cavity 12, the gas passes through the filter 2 arranged on the gas conveying path between the air inlet 11 and the air outlet 13. The filter 2 is essential and can effectively intercept harmful substances such as impurities, particles and microorganisms in the gas, ensuring that the gas flowing into the human body is pure and safe, and avoiding adverse effects on the patient. The filtered gas continues to flow in the valve cavity 12 and eventually enters the air guide pipe 5 connected with the air outlet 13, and is guided into the human body through the air guide pipe 5, that is, the gas is filtered before being inhaled by the human body. During the process of exhaling gas by the human body, when the gas pressure in the valve cavity 12 is too high, the gas is discharged to the outside environment through the exhaust port 14, thereby maintaining the stable pressure in the valve cavity 12 and ensuring the normal function of the human body to exhale gas. The vibration assembly 3 is installed on the breathing valve body 1 and abuts against the air guide pipe 5. During the operation of the breathing valve, the vibration assembly 3 generates vibration through a power source (such as electromagnetic drive or motor drive) and transmits the vibration to the air guide pipe 5 abutting against it. This vibration can effectively prevent the problem of sputum clumping on the side of the air guide pipe 5 close to the respiratory tract of the human body, thereby assisting the patient to expectorate sputum.

[0029] Preferably, in the present embodiment, the breathing valve body 1 comprises an air inlet valve body 16 and an air outlet valve body 17, the air inlet 11 is arranged on the air inlet valve body 16, the air outlet 13 is arranged on the air outlet valve body 17, the air inlet valve body 16 is detachably connected with the air outlet valve body 17, and the filter 2 is arranged on the air inlet valve body 16 or the air outlet valve body 17. In this way, the air inlet valve body 16 and the air outlet valve body 17 are detachably connected, and when the filter 2 needs to be replaced or cleaned, the entire breathing valve does not need to be disassembled, and the filter 2 can be quickly replaced by only separating the air inlet valve body 16 and the air outlet valve body 17. In the medical use scenario, the filter 2 may adsorb a large amount of impurities or microorganisms due to long-term use, and this design allows medical staff to quickly complete the maintenance work of the filter 2 without interrupting the connection of the entire pipeline, greatly improving the operation efficiency. Compared with the traditional integrated breathing valve, the whole is avoided. Discarded, reducing the cost of consumables.

[0030] Preferably, in the present embodiment, the breathing valve body 1 further comprises a lifting plate 18, the lifting plate 18 is located in the valve cavity 12 and is slidably sleeved with the valve cavity 12, and the lifting plate 18 divides the valve cavity 12 into an oxygen containing cavity 121 and an exhalation passage cavity 122; the lifting plate 18 is provided with a gas permeable hole 182, both ends of the gas permeable hole 182 are connected with the oxygen containing cavity 121 and the exhalation passage cavity 122 respectively, and the oxygen containing cavity 121, the gas permeable hole 182, the exhalation passage cavity 122 and the exhaust port 14 are sequentially communicated; the exhaust port 14 is communicated with the exhalation passage cavity 122; the lifting plate 18 is provided with a shielding part 183, the shielding part 183 blocks the exhaust port 14 when it is close to the air outlet 13, and the shielding part 183 opens the exhaust port 14 when it is away from the air outlet 13. The gas permeable hole 182 is sequentially reduced along the gas flow direction, which can make the gas pressure of the exhalation passage cavity 122 smaller during the inhalation stage of the breathing valve, drive the lifting plate 18 to press down, and thus close the gas permeable hole 182. During the inhalation stage of the breathing valve body 1, the external oxygen flows into the oxygen containing cavity 121, the airflow pressure drives the lifting plate 18 to slide towards the air outlet 13, so that the oxygen passes through the gas permeable hole 182, the exhalation passage cavity 122, and finally enters the air guide pipe 5 for the patient to inhale. During this process, the movement of the lifting plate 18 ensures one-way oxygen delivery and prevents exhalation residual gas from backflowing. During the exhalation stage, the exhalation airflow drives the lifting plate 18 to slide in the opposite direction, the shielding part 183 opens the exhaust port 14, and the waste gas exhaled by the patient flows from the exhalation passage cavity 122 to the exhaust port 14, and then to the external environment. This way of physically separating the inhalation and exhalation paths avoids gas mixing and reduces the risk of cross contamination, ensuring patient safety in medical scenarios.

[0031] Preferably, in the present embodiment, the breathing valve body 1 is provided with a limiting structure 7, which is arranged between the lifting plate 18 and the air outlet 13, and is used to block the lifting plate 18 from moving close to the air outlet 13. In this way, the limiting structure 7 can effectively prevent the lifting plate 18 from moving too close to the air outlet 13. During the operation of the breathing valve, whether the airflow pushes the lifting plate 18 to slide towards the air outlet 13 during inhalation, or in abnormal situations (such as sudden changes in airflow pressure), the limiting structure 7 can timely play a role to limit the displacement of the lifting plate 18. This avoids the lifting plate 18 from moving out of the normal working range due to excessive sliding, ensures that the key components such as the air permeable hole 182 and the shielding part 183 are in the correct position, thereby maintaining a stable gas flow path, and ensures that the breathing valve can continuously and stably operate under various working conditions, and will not cause abnormal gas supply due to out-of-control position of the lifting plate 18.

[0032] Preferably, in the present embodiment, the limiting structure 7 is provided with a plugging column 71, which corresponds to the air permeable hole 182 and is used to plug the air permeable hole 182. In this way, the corresponding arrangement of the plugging column 71 and the air permeable hole 182 realizes fine regulation during the breathing stage. During the inhalation stage, when the lifting plate 18 slides towards the air inlet 11, the plugging column 71 can timely and accurately insert into the air permeable hole 182, thereby blocking the passage between the oxygen containing cavity 121 and the exhalation passing cavity 122. At this time, the exhalation stage is entered, and the exhaled gas can only be discharged through the air outlet 14, which avoids the backflow of gas to the oxygen containing cavity 121 during the exhalation process, prevents the exhaled waste gas from polluting the pure oxygen source, ensures that the patient inhales fresh and uncontaminated oxygen during the next inhalation, and greatly improves the accuracy and purity of the gas flow direction during the breathing process.

[0033] Preferably, in the embodiment, one end of the tension spring 72 away from the limiting structure 7 is connected with the lifting plate 18, and the tension spring 72 is used to drive the lifting plate 18 to approach the air outlet 13. In this way, the elastic driving force of the tension spring 72 can assist the lifting plate 18 to quickly reset to block the air outlet 14, so that the patient can normally inhale oxygen from the oxygen containing cavity 121 and the exhalation passage cavity 122. After the end of the inhalation stage, the patient enters the exhalation stage, and based on the fact that the lifting plate 18 has blocked the air hole 182 at this time, the air pressure in the exhalation passage cavity 122 is increased, thereby pushing the lifting plate 18 to rise, and the lifting plate 18 drives the shielding part 183 to move to unblock the air outlet 14, so that the patient's exhaled airflow flows from the exhalation passage cavity 122 to the air outlet 14. The patient's exhalation causes the tension spring 72 to pull the lifting plate 18 to move the shielding part 183, so that the shielding part 183 blocks the air outlet 14, thereby allowing the next round of inhalation to be opened, and the cycle is repeated. Compared with relying only on the airflow to push the lifting plate 18 to reset, the assistance of the tension spring 72 greatly shortens the reset time, improves the gas delivery efficiency of the breathing valve, ensures that the patient can obtain sufficient oxygen supply at the moment of inhalation, and is especially suitable for patients with faster breathing frequency, and guarantees the continuity of the breathing process.

[0034] Preferably, in the embodiment, the breathing valve body 1 is provided with a guide rail 15, and the lifting plate 18 is provided with a guide block 181 which is slidably matched with the guide rail 15. In this way, the sliding match of the guide rail 15 and the guide block 181 provides the lifting plate 18 with a precise movement track. During the working process of the breathing valve, whether the airflow pushes the lifting plate 18 to move during inhalation or the tension spring 72 assists the lifting plate 18 to reset during exhalation, the guide block 181 always slides along the guide rail 15, avoiding the lifting plate 18 from deviating, shaking or being stuck. Even in the case of large airflow pressure fluctuation or uneven patient breathing strength, this structure can ensure that the lifting plate 18 stably moves in the intended direction, maintains the key components such as the air hole 182 and the shielding part 183 in the correct position, and guarantees the continuity and stability of the gas delivery of the breathing valve, and does not cause abnormal gas supply due to the out-of-control position of the lifting plate 18.

[0035] Preferably, in the present embodiment, the filter 2 is arranged between the exhalation passage cavity 122 and the gas outlet 13. In this way, the filter 2 can perform the final and accurate filtration on the gas about to enter the human body. After the gas flows from the oxygen containing cavity 121 into the exhalation passage cavity 122 through the gas permeable hole 182, the filter 2 is the last barrier for the gas output, which can effectively intercept the impurities such as residual micro-particles, microorganisms, odor molecules, etc. Compared with arranging the filter 2 at the gas inlet 11 or other positions, the filtration at this position is closer to the patient's inhalation end, which can ensure that the gas inhaled by the patient finally reaches the highest purity standard. For example, in a medical environment, even if the upstream filtration link fails partially, the filter 2 at this position can still ensure the safety of the patient's breathing and prevent harmful substances from entering the human body, thereby improving the protection performance of the breathing valve.
