Description

Technical Field

[0001] The invention relates to the technical field of medical devices, and in particular to a carbon dioxide storage mask. Background Art

[0002] The cause of respiratory alkalosis is that the rate of carbon dioxide discharge exceeds the rate of production, leading to hyperventilation, a decrease in carbon dioxide, and a decrease in arterial oxygen partial pressure. The overall cause is divided into central hyperventilation and peripheral hyperventilation, which are mainly manifested as hyperventilation and rapid breathing. Alkalosis can stimulate nerves and muscles, increasing their excitability. Acute mild cases may manifest as numbness and tingling in the lips and limbs, muscle tremors, and severe cases may have dizziness, syncope, blurred vision, convulsions, and some may be accompanied by chest tightness, chest pain, dry mouth, abdominal distension, etc. The common feature of respiratory alkalosis caused by various reasons is hyperventilation.

[0003] For patients with respiratory alkalosis, increasing the amount of carbon dioxide inhaled is used clinically to maintain the carbon dioxide balance in the patient's body. In view of this treatment method, the prior art has designed an oxygen mask with the function of storing part of the carbon dioxide.

[0004] For example, a carbon dioxide storage oxygen mask with publication number CN203139325U includes a mask body made of medical plastic, which is a plate-shaped triangular three-dimensional structure. The mask body is provided with an oxygen inlet and a carbon dioxide discharge hole, the carbon dioxide discharge hole is located in the middle of the mask body and a carbon dioxide discharge pipe is installed on the carbon dioxide discharge hole. The length and thickness of the carbon dioxide discharge pipe are adjusted according to the actual situation, and finally the storage time of the exhaled gas is adjusted to adapt to different patient conditions. The oxygen inlet is located on any side of the mask body, and an oxygen access pipe is installed on the oxygen inlet;

[0005] When used, the patent application can improve the symptoms of respiratory alkalosis by storing the exhausted carbon dioxide in the mask body so that the patient can inhale it again. However, after the patient inhales part of the carbon dioxide for treatment, the amount of carbon dioxide exhaled will change, and because of changes in the condition, the amount of carbon dioxide required to be inhaled varies from patient to patient. Therefore, the carbon dioxide discharge tube in the patent application is designed as a fixed structure, and when used, it is impossible to change the storage amount of carbon dioxide of the entire oxygen mask in real time according to the change in the amount of carbon dioxide exhaled by the patient, which results in that the patient with respiratory alkalosis does not receive effective treatment when using the carbon dioxide storage oxygen mask.

[0017] Furthermore, the outer wall of the exhaust plate is provided with a circle of silicone coating.

[0018] At least one of the above technical solutions adopted in the embodiments of the present invention can achieve the following beneficial effects:

[0019] Firstly, since patients with respiratory alkalosis need to increase the amount of carbon dioxide inhaled to maintain the carbon dioxide balance in the patient's body in clinical practice, the lower gas storage tube can be displaced on the upper gas storage tube according to the partial pressure of carbon dioxide at the end of exhalation of the patient, so as to change the storage tube's capacity for carbon dioxide.

[0020] Secondly, in the present invention, the storage tube is configured to be composed of two components, an upper gas storage tube and a lower gas storage tube, so that the storage capacity of carbon dioxide in the storage tube can be changed. At the same time, according to the detection and analysis of the patient's exhaled gas by the end-tidal carbon dioxide analyzer, when a patient with low end-tidal carbon dioxide partial pressure receives initial treatment, the patient's end-tidal carbon dioxide partial pressure is low, and the end-tidal carbon dioxide analyzer will transmit the partial pressure value to the control unit, and the control unit will issue an operating instruction to the micro-electric cylinder, so that the output end of the micro-electric cylinder extends outward to drive the push block and the lower gas storage tube to move synchronously, so that the upper gas storage tube and the lower gas storage tube can accommodate more carbon dioxide, and allow the patient to inhale more carbon dioxide when inhaling next time, and combine with oxygen for a period of treatment.

[0021] Thirdly, if the end-tidal carbon dioxide analyzer detects that the patient's end-tidal carbon dioxide partial pressure is elevated, the control unit may issue an operating instruction to the micro-electric cylinder, causing the output end of the micro-electric cylinder to operate, thereby reducing the carbon dioxide capacity of the upper and lower gas storage tubes. The carbon dioxide exhaled by the patient will be discharged into the oxygen mask body and the storage tube, while the carbon dioxide exceeding the capacity of the oxygen mask body and the storage tube will be discharged from the multiple air permeable grooves at the bottom of the lower gas storage tube. As the carbon dioxide capacity in the oxygen mask body and the storage tube decreases, the amount of carbon dioxide that the patient can inhale during inhalation will also decrease. This is suitable for patients with elevated end-tidal carbon dioxide partial pressure.

[0022] Fourthly, in the present invention, a cover is sleeved on the part near the bottom of the lower gas storage pipe, and the corresponding positions of the multiple air grooves on the cover and the multiple air grooves at the bottom of the lower gas storage pipe are changed by rotating the cover, thereby changing the gas discharge speed of the air grooves at the bottom of the lower gas storage pipe.

[0023] Fifthly, when the present invention is used clinically as an oxygen inhalation mask for storing carbon dioxide, the installation method of each one-way exhaust valve and the disassembly and assembly state of the storage tube can be changed, so that the entire mask can be used in more ways in addition to being used as an oxygen inhalation mask for storing carbon dioxide, so that patients with different stages of end-tidal carbon dioxide partial pressure can use it, so that the entire mask has a richer range of applications.

DETAILED DESCRIPTION

[0036] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] The technical solutions provided by various embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0038] The embodiment of the present invention provides a carbon dioxide storage mask, comprising an oxygen absorption mask body 1 and a storage tube 2;

[0039] Refer to the attached Figures 1 to 4 As shown, the oxygen mask body 1 can be worn on the patient's mouth and nose, and can cover the patient's mouth and nose 25. Both sides of the oxygen mask body 1 are connected with straps that can be tied to the patient's head. The oxygen mask body 1 is designed to be concave corresponding to the mouth and nose of the human body when worn, so that the interior of the oxygen mask body 1 is formed with a placement table 11 for the storage tube 2 to be connected in a vertical state. The placement table 11 is provided with a socket 12 that matches the outer diameter of the storage tube 2. The socket 12 is connected to the inner side of the oxygen mask body 1. The storage tube 2 is vertically arranged on the outer side of the oxygen mask body 1, and the top end of the storage tube 2 is inserted into the socket 12. An extension tube 3 that can be connected to the oxygen tube of the oxygen supply equipment is provided on the storage tube 2.

[0040] Preferably, see Attachment Figures 5 to 8As shown, the storage pipe 2 includes an upper gas storage pipe 21 and a lower gas storage pipe 22, and a through hole 23 is provided inside the upper gas storage pipe 21 and the lower gas storage pipe 22;

[0041] The through hole 23 inside the upper gas storage pipe 21 penetrates both ends of the upper gas storage pipe 21, so that the upper gas storage pipe 21 forms a tubular structure, and the through hole 23 inside the lower gas storage pipe 22 only penetrates the top portion of the lower gas storage pipe 22. The inner diameter of the through hole 23 inside the lower gas storage pipe 22 matches the outer diameter of the upper gas storage pipe 21. The through hole 23 of the lower gas storage pipe 22 is sleeved on the upper gas storage pipe 21, and the lower gas storage pipe 22 can move on the upper gas storage pipe 21. The bottom end of the lower gas storage pipe 22 is provided with a plurality of air-permeable grooves 24, and the plurality of air-permeable grooves 24 are all arc-shaped, and the plurality of air-permeable grooves 24 are equidistantly arranged around the center of the bottom end of the lower gas storage pipe 22.

[0042] The oxygen mask body 1 can be worn on the patient's mouth and nose to be used as an oxygen supply mask, and the storage tube 2 arranged on the outside of the oxygen mask body 1 can expand the space between the inner side of the oxygen mask body 1 and the patient's mouth and nose. When the patient exhales, the exhaled carbon dioxide will be collected in the oxygen mask body 1 and the storage tube 2, and the storage tube 2 composed of the upper gas storage tube 21 and the lower gas storage tube 22 can change the usable length of the storage tube 2 when adjusting, so that the space inside the storage tube 2 that can accommodate carbon dioxide changes. When the patient exhales, the carbon dioxide that exceeds the storage capacity of the oxygen mask body 1 and the storage tube 2 will be slowly discharged from the multiple air permeable grooves 24 at the bottom of the lower gas storage tube 2;

[0043] When the oxygen supply device delivers oxygen to the storage tube 2 through the oxygen pipe, the oxygen will be discharged from the storage tube 2 into the oxygen mask body 1 for the patient to inhale. During the inhalation, the carbon dioxide retained in the oxygen mask body 1 will be inhaled by the patient together with the oxygen delivered by the oxygen supply device. Since the patient with respiratory alkalosis needs to increase the carbon dioxide inhalation amount to maintain the carbon dioxide balance in the patient's body in clinical practice, the storage tube 2 can cooperate with the oxygen mask body 1 to increase the storage of carbon dioxide, thereby increasing the carbon dioxide inhalation amount of the patient;

[0044] In actual application, the displacement of the lower gas storage tube 22 on the upper gas storage tube 21 can be adjusted according to the partial pressure of the patient's end-tidal carbon dioxide, so as to change the storage tube 2's accommodating space for carbon dioxide.

[0045] Preferably, see Attachment Figure 6 As shown, the upper gas storage tube 21 is provided with a micro electric cylinder 4 whose output end is a straight running track, and the micro electric cylinder 4 is fixedly sleeved on the outer wall of the upper gas storage tube 21 through a matching limiting bracket 41;

[0046] The output end of the micro-electric cylinder 4 is arranged toward the lower gas storage tube 22, and a push block 42 is fixedly arranged on the output end of the micro-electric cylinder 4. The push block 42 is fixedly connected to the outer wall of the lower gas storage tube 22. The operation of the output end of the micro-electric cylinder 4 can drive the push block 42 to drive the lower gas storage tube 22 to perform telescopic displacement in a sleeved state on the upper gas storage tube 21.

[0047] Refer to the attached Figures 1 to 3 As shown, it also includes an end-tidal carbon dioxide analyzer 5, and a trachea 51 is arranged on the placement platform 11 of the oxygen mask body 1, one end of the trachea 51 is connected to the interior of the oxygen mask body 1 and the other end is connected to the detection port of the end-tidal carbon dioxide analyzer 5, and the end-tidal carbon dioxide analyzer 5 and the micro-electric cylinder 4 are both controlled by the control unit;

[0048] In clinical practice, if the treatment of respiratory alkalosis is not timely, severe cases may experience impaired consciousness and convulsions. Such patients often show dyspnea, labored and rapid breathing, numbness or abnormal sensation in the extremities, face, lips, etc. Therefore, timely and effective intervention is crucial to the treatment of this disease. This is also the focus of clinical, especially emergency internal medicine medical staff. By giving oxygen inhalation containing a certain amount of carbon dioxide to increase the arterial oxygen partial pressure in the arterial blood and stimulate the respiratory center, etc.

[0049] However, in actual application, the patient's symptoms will not be relieved during the initial stage of inhaling oxygen containing a certain amount of carbon dioxide. However, as time goes by, the partial pressure of carbon dioxide at the end of the patient's exhalation will gradually increase from a low level. Therefore, the amount of carbon dioxide contained in the oxygen given to the patient should also be reduced to avoid discomfort symptoms such as dyspnea caused by inhaling excessive oxygen containing carbon dioxide after the partial pressure of carbon dioxide at the end of the patient's exhalation increases. However, it is difficult for medical staff to manually change the storage tube 2's capacity for carbon dioxide in real time according to the partial pressure of carbon dioxide at the end of the patient's exhalation.

[0050] The fixed structure of the carbon dioxide discharge pipe in the carbon dioxide storage oxygen inhalation mask of CN203139325U is obviously not enough for patients with high and low changes in the carbon dioxide partial pressure at the end of exhalation. The fixed structure of the carbon dioxide discharge pipe will limit the storage capacity of the patient's exhaled carbon dioxide by the mask body and the carbon dioxide discharge pipe.

[0051] To this end, the storage tube 2 is configured in the present invention to consist of an upper gas storage tube 21 and a lower gas storage tube 22, so that the storage amount of carbon dioxide in the storage tube 2 can be changed. At the same time, a micro-electric cylinder 4 is provided on the upper gas storage tube 21. In actual application, the control command of the control unit can be set so that the micro-electric cylinder 4 can detect and analyze the patient's exhaled gas according to the end-tidal carbon dioxide analyzer 5. When a patient with a low end-tidal carbon dioxide partial pressure receives initial treatment, the carbon dioxide exhaled by the patient will be collected in the oxygen mask body 1 and the storage tube 2, and then oxygen containing part of the carbon dioxide will be inhaled during inhalation. When the patient exhales for the second time, the end-tidal carbon dioxide partial pressure will be collected in the storage tube 2. The carbon dioxide analyzer 5 will combine and analyze the amount of carbon dioxide in the oxygen mask body 1 and the storage tube 2 and the amount of carbon dioxide exhaled by the patient. If the patient's end-tidal carbon dioxide partial pressure is low, the end-tidal carbon dioxide analyzer 5 will transmit the partial pressure value to the control unit, and the control unit will issue an operation instruction to the micro-electric cylinder 4, so that the output end of the micro-electric cylinder 4 extends outward to drive the push block 42 and the lower gas storage tube 22 to move synchronously, so that the upper gas storage tube 21 and the lower gas storage tube 22 can accommodate more carbon dioxide, and the patient can inhale more carbon dioxide when inhaling next time, and combine with oxygen for a period of treatment;

[0052] During this period, if the end-tidal carbon dioxide analyzer 5 detects that the patient's end-tidal carbon dioxide partial pressure increases, the control unit will send an operation command to the micro-electric cylinder 4, so that the output end of the micro-electric cylinder 4 retracts a certain distance, so as to drive the push block 42 and the lower gas storage tube 22 to move in the opposite direction for a certain distance, so that the upper gas storage tube 21 and the lower gas storage tube 22 can reduce the capacity of carbon dioxide. When the patient exhales, the exhaled carbon dioxide will be discharged into the oxygen mask body 1 and the storage tube 2, and the carbon dioxide exceeding the capacity of the oxygen mask body 1 and the storage tube 2 will be discharged from the multiple air permeable grooves 24 at the bottom end of the lower gas storage tube 22. As the carbon dioxide capacity in the oxygen mask body 1 and the storage tube 2 decreases, the amount of carbon dioxide that the patient can inhale during inhalation will also decrease. This can be suitable for patients with increased end-tidal carbon dioxide partial pressure.

[0053] Secondly, since the conditions of each patient are different, the end-tidal carbon dioxide partial pressure will also vary, and there will not be a gradual increase in the partial pressure. Therefore, the control unit in the present invention can combine the end-tidal carbon dioxide partial pressure of the patient with the end-tidal carbon dioxide analyzer 5 to issue different operating instructions to the micro-cylinder 4, so that the micro-cylinder 4 can control the displacement distance of the lower gas storage tube 22 according to the actual situation of the patient, thereby changing the real-time change of the carbon dioxide capacity of the storage tube 2, so that the entire mask can be used in clinical medicine, providing better treatment conditions for patients with respiratory alkalosis.

[0054] Preferably, see Attachment Figure 7 and 8 As shown, a cover 25 is sleeved on the lower gas storage pipe 22 near the bottom end, and the cover 25 can be rotated in a sleeved state on the outer wall of the lower gas storage pipe 22. The bottom end of the cover 25 is provided with a plurality of air permeable grooves 24, and the number and position of the plurality of air permeable grooves 24 at the bottom end of the cover 25 and the bottom end of the lower gas storage pipe 22 are the same, and the outer wall of the cover 25 is provided with anti-slip grooves;

[0055] In actual application, the corresponding positions of the multiple air grooves 24 on the cover 25 and the multiple air grooves 24 at the bottom of the lower gas storage tube 22 can be changed by rotating the cover 25, so as to change the gas discharge speed of the air grooves 24 at the bottom of the lower gas storage tube 22. The outer wall of the cover 25 is provided with anti-slip grooves, which can increase the friction when the medical staff manually manipulates the outer wall of the cover 25, so as to facilitate more stable micro-rotation adjustment of the cover 25. During operation, if the multiple air grooves 24 at the bottom of the cover 25 completely correspond to the multiple air grooves 24 at the bottom of the lower gas storage tube 22, the multiple air grooves 24 at the bottom of the lower gas storage tube 22 are in the maximum open state. When the patient exhales, the excess carbon dioxide in the oxygen mask body 1 and the storage tube 2 can be discharged from the multiple air grooves 24 at the bottom of the lower gas storage tube 22 at the maximum discharge speed;

[0056] If the multiple air grooves 24 at the bottom end of the cover 25 are misaligned with the multiple air grooves 24 at the bottom end of the lower air storage tube 22, the portion of the bottom end of the cover 25 where no air grooves 24 are provided will block and cover the air grooves 24 at the bottom end of the lower air storage tube 22 to a certain extent, thereby reducing the discharge space for carbon dioxide from the multiple air grooves 24 at the bottom end of the lower air storage tube 22, thereby reducing the discharge rate of carbon dioxide, so that the entire mask can be adjusted according to the patient's condition for a more detailed treatment plan, allowing patients with too low end-tidal carbon dioxide partial pressure to inhale more carbon dioxide.

[0057] Preferably, see Attachment Figure 5 As shown, the inner wall of the plug hole 12 on the placement platform 11 is provided with a thread 26 groove, and the outer wall of the top end of the upper gas storage pipe 21 that can be inserted into the plug hole 12 is provided with a thread 26 that matches the thread 26 groove;

[0058] When installing the storage tube 2, the top end of the upper gas storage tube 21 in the storage tube 2 can be inserted along the insertion hole 12 on the placement platform 11 and rotated, so that the thread 26 at the top end of the upper gas storage tube 21 and the insertion hole 12 form a thread 26 match, thereby completing the installation connection between the storage tube 2 and the oxygen mask body 1, so that the oxygen mask body 1 and the storage tube 2 are a detachable structure, so as to facilitate disinfection and cleaning before and after use;

[0059] At the same time, the length and diameter of the upper gas storage tube 21 and the lower gas storage tube 22 in the storage tube 2 can be prepared in various specifications in the present invention, so as to be suitable for patients with greater changes in the end-tidal carbon dioxide partial pressure in clinical practice, thereby facilitating the installation and storage of the gas on the oxygen mask body 1 for the patient without having to remove the oxygen mask and the oxygen-deprived state, thereby avoiding discomfort symptoms caused by the patient being in the oxygen-deprived state.

[0060] Preferably, see Attachment Figures 1 to 3 As shown, the oxygen mask body 1 is provided with a plurality of placement holes corresponding to the patient's nose, and each placement hole is provided with a one-way exhaust valve 6;

[0061] Refer to the attached Fig. 9 As shown, each of the one-way exhaust valves 6 includes an exhaust plate 61 and a baffle 62. The exhaust plate 61 is arranged at the placement hole on the oxygen mask body 1. The exhaust plate 61 and the baffle 62 are the same size as the placement hole. The exhaust plate 61 is provided with a plurality of exhaust holes 63 around its central portion. The baffle 62 is made of a thin and flexible silicone material. The baffle 62 is arranged on the exhaust plate 61 and faces the inner side of the oxygen mask body 1. A support rod 64 is arranged at the center of the exhaust plate 61. One end of the support rod 64 is fixedly connected to the exhaust plate 61 and the other end passes through the center of the baffle 62. A baffle 65 larger than the outer diameter of the support rod 64 is fixedly arranged on one end of the support rod 64 that passes through the baffle 62, so that the baffle 62 will not fall off the support rod 64.

[0062] When the present invention is used clinically as an oxygen mask for storing carbon dioxide, each placement hole needs to be blocked, and each one-way exhaust valve 6 can be disassembled and installed at the corresponding placement hole on the oxygen mask body 1, so that the entire mask can be used as an oxygen mask for storing carbon dioxide and can also provide more usage methods:

[0063] When the patient's end-tidal carbon dioxide partial pressure is close to the normal value of 30-45 mmHg, the present invention can be used for such patients. The operation method is as follows: all the exhaust plates 61 are installed on the installation holes of the oxygen mask body 1, and the exhaust plates 61 are facing the inner side of the oxygen mask body 1, and the baffle 62 is located on the outer side of the oxygen mask body 1, and then the lower gas storage tube 22 is adjusted to the position closest to the top end of the upper gas storage tube 21, so that the storage tube 2 has the minimum storage capacity of carbon dioxide, and the cover 25 is rotated so that the position where the air permeable grooves 24 are set on the cover 25 is in a fully shielded state with the shape of the multiple air permeable grooves 24 at the bottom end of the lower gas storage tube 22. When in use, the oxygen supply equipment supplies oxygen normally, and the patient inhales Oxygen can be inhaled when the patient breathes in, and when the patient exhales, the exhaled carbon dioxide will be discharged into the oxygen mask body 1, and the excess carbon dioxide will flow along with the patient's exhaled airflow through the multiple exhaust holes 63 on the exhaust plate 61 to impact the baffle 62. Since the baffle 62 is made of a thin and flexible silicone material, the airflow will impact the baffle 62 covering the exhaust holes 63 on the exhaust plate 61, causing the baffle 62 to deform toward the outside of the oxygen mask body 1, and the block 65 on the support rod 64 can block the baffle 62 to prevent the baffle 62 from falling off the exhaust plate 61, thereby exposing the multiple exhaust holes 63 on the exhaust plate 61 and allowing the carbon dioxide to be discharged from the oxygen mask body 1.

[0064] When the patient's end-tidal carbon dioxide partial pressure is a normal value of 30 to 45 mmHg, the present invention can be used as a conventional oxygen mask. The operation method is as follows: remove the entire storage tube 2, and seal the jack 12 on the oxygen mask body, install all the exhaust plates 61 on the placement holes of the oxygen mask body 1, and make the exhaust plates 61 face the inner side of the oxygen mask body 1, while the baffle 62 is on the outer side of the oxygen mask body 1. When in use, since there is no storage tube 2 on the oxygen mask body 1, the oxygen mask body 1 has a normal capacity for accommodating the carbon dioxide exhaled by the patient.

[0065] When the patient's end-tidal carbon dioxide partial pressure is close to the normal value of 30-45 mmHg, but the patient needs to undergo breathing exercises, the present invention can be used as an exercise mask. The operation method is: without removing the storage tube 2, the cover 25 is rotated so that the cover 25 forms a full shielding state for the multiple air permeable grooves 24 at the bottom end of the lower air storage tube 22;

[0066] In the present invention, taking the total number of one-way exhaust valves 6 as two as an example, one of the exhaust plates 61 is installed on the installation hole of the oxygen mask body 1, and the exhaust plate 61 is directed toward the outside of the oxygen mask body 1, and the baffle 62 is located on the inside of the oxygen mask body 1; the other exhaust plate 61 is installed on another corresponding installation hole of the oxygen mask body 1 in a state facing the inside of the oxygen mask body 1, and the baffle 62 is located on the outside of the oxygen mask body 1, that is, the installation directions of the two one-way exhaust valves 6 on the oxygen mask body 1 are opposite, and the oxygen supply equipment is switched to the shutdown state, that is, the oxygen supply equipment does not supply oxygen. When in use, during the patient's inhalation process, external air will enter the interior of the oxygen mask body 1 from the multiple exhaust holes 63 on the exhaust plate 61 directed toward the outside of the oxygen mask body 1. Since the baffle 62 is located on the inside of the oxygen mask body, when the patient inhales, the negative The compressed air flow will cause the baffle 62 to deform inward and allow external air to enter the interior of the oxygen mask body for the patient to inhale. When exhaling, the exhaled carbon dioxide will be discharged from the oxygen mask body 1 through the multiple exhaust holes 63 on the exhaust plate 61 facing the inside of the oxygen mask body 1. Since the baffle 62 is located on the outside of the oxygen mask body, when the patient inhales, the external air will enter the interior of the oxygen mask body 1 through the multiple exhaust holes 63 on the exhaust plate 61 facing the outside of the oxygen mask body 1 and the baffle 62, so that the entire mask can allow the patient to practice autonomous breathing when worn. In order to prevent the patient from having difficulty breathing during the exercise, the oxygen mask body 1 must always be worn on the patient's mouth and nose when in use, so that medical staff can turn on the oxygen supply equipment at any time to supply oxygen to the inside of the oxygen mask body 1, so as to prevent the patient from having unexpected situations due to poor autonomous breathing.

[0067] Preferably, the outer wall of the exhaust plate 61 is provided with a circle of silicone coating;

[0068] When the exhaust plate 61 is installed from the inside or outside of the oxygen mask body 1 into the installation hole, the silicone coating on the outer wall of the exhaust plate 61 can increase the friction between the outer wall of the exhaust plate 61 and the inner wall of the installation hole of the oxygen mask body 1, so that the exhaust plate 61 can be installed in the installation hole on the oxygen mask body 1, and the exhaust plate 61 will not fall off from the installation hole due to the influence of the patient's breathing airflow.
