Description

Technical Field

[0001] The invention belongs to the technical field of medical equipment, in particular to an improved oxygen mask for a high-flow respiratory humidification therapeutic apparatus. Background Art

[0002] High-flow respiratory humidification therapy is a treatment method that continuously provides patients with high-flow inhaled gas with adjustable and relatively constant oxygen concentration, temperature and humidity through high-flow nasal plugs or other patient interfaces. It mainly consists of an air-oxygen mixing device, a heated humidification device, a high-flow nasal plug or other patient interface, and a connected breathing circuit. This treatment method is often used in clinical practice for patients with mild to moderate hypoxemia, such as hypoxic respiratory failure, ARDS, pneumonia, pulmonary fibrosis, cardiogenic pulmonary edema, etc. It has multiple physiological effects such as improving blood oxygen, flushing physiological anatomical dead space, generating a certain amount of positive end-expiratory pressure, reducing upper airway resistance and breathing work.

[0003] Traditional high-flow respiratory humidification therapy devices are often used in conjunction with high-flow nasal plugs. For patients with rhinitis, nasal congestion, or those who have undergone nasal access surgery, as well as patients who habitually breathe with their mouths open, the treatment effect is poor or cannot be used. In addition, nasal plugs placed in the nasal cavity for a long time may also cause physical damage to the inner wall of the nasal cavity. After a period of development, oxygen masks have been widely used as breathing interfaces for high-flow respiratory humidification therapy devices, but existing oxygen masks still have some problems. The oxygen masks commonly used in high-flow oxygen therapy are similar to ordinary oxygen masks and are only fixed behind the head through an elastic band through the patient's ear edge. The fixation effect is poor and it is easy to cause local pain and pressure sores. In addition, patients are generally in a supine position. When they adjust their posture on the bed, the elastic band is easily displaced, which in turn pulls and affects the position of the oxygen mask, causing the oxygen mask to fall off or shift, resulting in insufficient oxygen supply and affecting the patient's life safety.

[0004] To this end, it is necessary to propose an improved high-flow respiratory humidification therapy device oxygen mask that can adaptively adjust the tightness of the strap, reinforce the oxygen mask when the oxygen mask is pulled, reduce the discomfort of wearing the oxygen mask, and improve the flexibility of the oxygen mask in cooperating with the patient's physiological needs, thereby enhancing the patient's comfort experience and reducing safety risks. Summary of the invention

[0005] In order to solve the above problems, the purpose of the present invention is to provide an improved high-flow respiratory humidification therapy device oxygen mask, which connects the side piston and the top piston to provide a buffer when the strap on one side is pulled, thereby reducing the pulling force while causing other pistons to displace, thereby strengthening the fixation of the oxygen mask, avoiding the displacement and falling off of the oxygen mask, improving the patient's wearing experience, and enhancing the safety of the oxygen mask.

[0006] In order to achieve the above-mentioned purpose, the technical scheme of the present invention is as follows: an improved high-flow respiratory humidification therapy device oxygen mask, comprising an oxygen mask, the outer walls on both sides of the oxygen mask are fixedly connected to side piston cylinders, the side piston cylinders are slidably matched with side pistons, the side pistons are fixedly connected to the side of the oxygen mask away from the side of the side connecting rods, the side connecting rods pass through the outer wall of the side piston cylinder and slide with the outer wall of the side piston cylinder, the ends of the side connecting rods away from the side pistons are fixedly connected to side straps, the top outer wall of the oxygen mask is fixedly connected to a support assembly, the support assembly is used to adjust the longitudinal angle of the oxygen mask, and the top of the support assembly is fixed A top piston cylinder is fixedly connected, a top piston is slidably fitted in the top piston cylinder, a top connecting rod is fixedly connected to the side of the top piston away from the oxygen mask, the top connecting rod passes through the outer wall of the top piston cylinder and slidably fits with the outer wall of the top piston cylinder, one end of the top connecting rod away from the top piston is fixedly connected to a top strap, the other end of the top strap is detachably connected to a connecting net, the connecting net and the side straps are both detachably connected, and length adjusters are provided on the side straps and the top strap; an annular trachea is laid on the side of the outer edge of the oxygen mask close to the patient's skin, the annular trachea extends into the supporting assembly, and the side piston cylinder and the top piston cylinder are both connected to the annular trachea.

[0007] The principle of the basic scheme is: the improved high-flow respiratory humidification therapy oxygen mask of the present invention realizes the stable fixation and comfortable wearing of the mask through the unique piston cylinder and connecting rod system design. When a side strap is pulled due to the patient's activity or position change, the side piston on this side will slide in the side piston cylinder, thereby absorbing and buffering the pulling force. Since the side piston cylinder and the top piston cylinder are both connected to the annular trachea, the piston movement on this side will produce airflow changes, which are transmitted to the top piston cylinder or other side piston cylinders through the internal annular trachea, causing the corresponding top piston or side piston to move and tighten other straps. This linkage mechanism can automatically adjust the overall fixed state of the mask to ensure that the mask fits firmly on the patient's face and avoids displacement or falling off. At the same time, the support assembly is not only used to adjust the longitudinal angle of the oxygen mask to adapt to the facial contours of different patients, but also serves as a fixed basis for the top piston cylinder to ensure the stable operation of the top piston cylinder. The design of the top strap and the connecting net further enhances the fixing effect of the mask while providing additional comfort. The setting of the length adjuster allows medical staff to flexibly adjust the tightness of the strap according to the actual situation of the patient to achieve the best fixation effect and wearing comfort.

[0008] The beneficial effects of the basic solution are: 1. The design of the piston cylinder and the connecting rod effectively buffers the direct pressure of the straps on the facial skin when they are pulled by external forces. This design not only reduces the discomfort caused by wearing the mask for a long time, but also avoids the displacement or falling off of the mask due to unstable fixation, thereby further improving the patient's wearing experience. In addition, the setting of the length adjuster allows medical staff to flexibly adjust the tightness of the straps according to the individual differences of the patients, ensuring that the mask can be firmly fixed without causing excessive pressure on the patient.

[0009] 2. Traditional oxygen masks are often prone to displacement or falling off due to a single fixing method or improper material selection. The mask of the present invention uses a piston-cylinder linkage mechanism to achieve automatic adjustment and firm fixation of the mask when subjected to external forces. When the strap on one side is pulled, the piston on that side will slide in the cylinder and transmit signals to other piston cylinders through the internal airway system, causing the corresponding piston to displace, thereby automatically adjusting the overall fixing state of the mask. This design not only improves the fixing stability of the mask, but also reduces the risk of treatment interruption or poor effect due to unstable fixation.

[0010] 3. Each patient's facial contour and breathing needs are unique. The mask of the present invention, through the design of the support assembly and the length adjuster, allows medical staff to flexibly adjust the longitudinal angle of the mask and the tightness of the straps according to the actual situation of the patient. This personalized adjustment method not only helps to ensure that the mask fits the patient's face perfectly, but also improves the pertinence and effectiveness of the treatment. At the same time, the detachable design of the connecting net and the side straps makes the mask more convenient and quick to clean, disinfect and replace, further improving the convenience and safety of treatment.

[0011] Furthermore, the support assembly includes a support bar, a support ring is fixedly connected to the top of the support bar, a support nut is rotatably connected to the support ring, a support bolt is threadedly engaged with the support nut, an end of the support bolt away from the support nut is fixedly connected to a support plate, a side of the support ring away from the support bar is fixedly connected to the top piston cylinder, and an annular air pipe extends into the support bar and the support ring.

[0012] The beneficial effects of the basic solution are: 1. The support strip, support ring, support nut and support bolt in the support assembly together form a highly adjustable support structure. This design allows medical staff to flexibly adjust the position and angle of the oxygen mask through the support sheet according to the patient's facial contour and breathing needs, thereby ensuring that the mask can fit the patient's face closely, reducing air leakage and improving treatment effects.

[0013] 2. The modular design of the support assembly makes it more convenient and quicker to clean and maintain. Medical staff can easily disassemble and assemble the various parts of the support assembly for thorough cleaning and disinfection. This design not only helps reduce the risk of cross infection, but also extends the service life of the mask and reduces medical costs.

[0014] 3. Through the sophisticated design of the support assembly, the present invention further improves the wearing comfort and satisfaction of the patient. The height and angle adjustability of the support assembly enable the mask to better adapt to the patient's facial contour and reduce the pressure on the facial skin. At the same time, the stability of the support assembly also ensures the stability of the mask during wearing, reducing the patient's discomfort caused by the shaking or displacement of the mask.

[0015] Furthermore, the oxygen mask can cover the patient's mouth and nose, and the oxygen mask is provided with a through hole corresponding to the patient's mouth, and a mouth elbow is rotatably connected in the through hole, and a rubber plug is plugged at one end of the mouth elbow away from the oxygen mask, and an inner fixing ring and an outer fixing ring are fixedly connected to the rubber plug, the inner fixing ring is used to plug the mouth elbow to fix the rubber plug, and the outer fixing ring is used to wrap around the outer side of the bottom end of the mouth elbow to receive dirt.

[0016] The beneficial effects of the basic solution are: 1. The oxygen mask can fully cover the patient's mouth and nose, ensuring efficient oxygen delivery. At the same time, the opening opened in the mask corresponding to the patient's mouth and equipped with a rotatable mouth elbow provide patients with a more comfortable breathing experience. The design of the mouth elbow allows patients to reduce direct impact on the inside of the mask when breathing, reducing pressure fluctuations inside the mask, thereby improving patient comfort.

[0017] 2. The rotating connection design between the mouth elbow and the through port ensures a tight connection between the mouth elbow and the mask, effectively preventing oxygen leakage. This design not only improves the sealing of the mask, but also ensures the efficient use of oxygen, avoiding insufficient treatment due to leakage.

[0018] 3. The design of the rubber plug, inner fixing ring and outer fixing ring makes the mouth elbow more convenient and quick to clean and maintain. Medical staff can easily remove and replace the rubber plug to thoroughly clean and disinfect the mouth elbow. This design not only helps reduce the risk of cross infection, but also extends the service life of the mask and mouth elbow, reducing medical costs.

[0019] 4. The design of the external fixing ring is not only used to fix the rubber plug, but also plays a role in receiving dirt. When the patient produces saliva or other dirt during breathing, the dirt can be effectively received by the external fixing ring and removed by disassembling the rubber plug, preventing the dirt from directly flowing into the mask or onto the patient, thereby improving the hygiene of the treatment and the comfort of the patient.

[0020] 5. The design of the mouth elbow makes the mask flexible during wearing. Medical staff can adjust the angle and position of the mouth elbow according to the patient's actual situation and breathing needs to ensure that the mask can better adapt to the patient's facial contour and breathing habits. This design not only improves the personalization of the mask, but also enhances its applicability among different patients.

[0021] Furthermore, the oxygen mask is provided with a vent corresponding to the position of the patient's nose, and a nasal elbow is rotatably connected in the vent, and the nasal elbow is connected to the output end of the high-flow respiratory humidification therapy device.

[0022] The beneficial effects of the basic solution are: 1. The design of the vent and the nasal elbow allows oxygen to be directly and efficiently delivered to the patient's nasal cavity. Compared with the traditional mask design, this design reduces the diffusion and waste of oxygen inside the mask and improves the utilization rate of oxygen.

[0023] 2. The nasal elbow is connected to the output end of the high-flow respiratory humidification therapy device and can rotate in the vent. This design allows the mask to have a certain degree of flexibility during wearing. Since the patient is in a supine position most of the time, the rotation of the nasal elbow can prevent the output end of the lateral high-flow respiratory humidification therapy device from being bent and affecting the gas delivery efficiency, thereby avoiding insufficient or interrupted treatment due to insufficient or unstable oxygen delivery.

[0024] 3. The combination of the vent and the nasal elbow allows the patient to feel a smoother airflow when breathing. Compared with the traditional mask design, this design reduces the feeling of suffocation caused by poor airflow inside the mask and improves the patient's breathing experience.

[0025] Furthermore, a plurality of exhaust holes are provided on the outer side of the curved portion of the mouth elbow.

[0026] The beneficial effects of the basic scheme are: 1. Through the upper vent and the exhaust holes on the lower mouth elbow, the humidified oxygen introduced from the upper side can drive the waste gas exhaled from the nasal cavity to move downward after flowing through the front of the nose and be discharged from the exhaust holes, forming a top-down oxygen flow in line with human bionics in the oxygen mask, thereby ensuring that the patient can always inhale freshly supplied humidified oxygen instead of inhaling exhaled waste gas.

[0027] 2. The design of the exhaust hole helps to balance the pressure inside the oral elbow and reduce the pressure fluctuation caused by breathing, so that the patient can breathe more smoothly. When the patient exhales, part of the waste gas can be discharged through the exhaust hole, avoiding the accumulation of waste gas in the oral elbow and reducing the patient's discomfort. In high-flow respiratory humidification therapy, humidified oxygen will produce a certain amount of mist. The setting of the exhaust hole helps to reduce the accumulation of mist in the oral elbow, avoiding excessive mist affecting the patient's vision or causing other discomfort.

[0028] Furthermore, the top strap and the side straps are detachably connected to the connecting net via Velcro.

[0029] The benefits of the basic solution are: 1. The Velcro design allows the top strap and side strap to be easily connected or separated from the connection net, greatly simplifying the wearing and removal process of the mask. Medical staff or patients can quickly adjust the tightness of the straps as needed to ensure that the mask fits the patient's face tightly while avoiding discomfort caused by overtightening. In addition, this design also makes it easier for patients to take a short break or move around without interrupting treatment, improving the flexibility and convenience of treatment.

[0030] 2. The detachable connection between the Velcro and the connection net allows the straps to be adjusted according to the patient's facial contour and comfort needs. By adjusting the length and position of the straps, patients can find the most suitable wearing method for themselves, thereby reducing the pressure on the facial skin and improving the wearing comfort. In addition, the Velcro design also makes the straps less likely to slip or loosen when worn for a long time, further enhancing the stability and comfort of the patient.

[0031] 3. The detachable connection between the Velcro and the connection net also facilitates the cleaning and maintenance of the mask. Medical staff can easily remove the straps to thoroughly clean and disinfect the mask and straps. This design not only helps reduce the risk of cross infection, but also extends the service life of the mask and straps, reducing medical costs.

[0032] Furthermore, a flexible layer is laid on the side of the top strap and the side strap close to the patient.

[0033] The beneficial effects of the basic solution are: 1. The laying of the flexible layer makes the top strap and the side strap softer and more comfortable when in contact with the patient's skin, reducing the pressure and friction on the facial skin. This design is especially suitable for patients who wear masks for a long time, and can effectively reduce the skin redness, pain or discomfort caused by long-term pressure, and improve the patient's overall wearing experience.

[0034] 2. The flexible layer not only increases the comfort of the straps, but also improves the stability of the mask to a certain extent. Since the flexible layer has a certain degree of elasticity and fit, it can better fit the patient's facial contour and reduce the loosening or slipping of the mask during wearing. This helps to ensure that the mask fits tightly during treatment, thereby improving the efficiency of oxygen delivery and the treatment effect.

[0035] Furthermore, the outer periphery of the annular trachea is wrapped with a first skin-friendly layer.

[0036] The beneficial effects of the basic solution are: 1. The wrapping of the first skin-friendly layer makes the annular trachea softer and more comfortable when in contact with the patient's facial skin. This soft material can effectively reduce the pressure and friction on the facial skin, and reduce the skin redness, pain or discomfort caused by wearing the mask for a long time. As the key part connecting the mask body and the patient's face, the material and comfort of the annular trachea are directly related to the patient's treatment experience and skin protection effect. The use of the first skin-friendly layer not only improves the softness and comfort of the airway, but also can reduce skin damage caused by friction or pressure to a certain extent.

[0037] 2. The first skin-friendly layer usually has a certain degree of elasticity and fit, which can better fit the patient's facial contour. This fit not only helps to improve the sealing of the mask and prevent oxygen leakage, but also ensures the stability of the mask during wearing. Stable mask wearing helps to ensure the continuity and stability of oxygen delivery, thereby improving the treatment effect.

[0038] Furthermore, a second skin-friendly friction layer is laid on the bottom of the supporting sheet.

[0039] The beneficial effects of the basic solution are: 1. The laying of the second skin-friendly friction layer makes the support sheet softer and more skin-friendly when in contact with the patient's face, reducing irritation and friction to the facial skin. This soft and skin-friendly material can significantly improve the patient's comfort when wearing the mask, and reduce skin redness, pain or discomfort caused by long-term wearing. This design is particularly important for patients with sensitive or easily damaged skin.

[0040] 2. The second skin-friendly friction layer not only improves comfort, but also enhances the stability of the mask to a certain extent. Because this layer has a certain degree of friction, it can better fit the patient's forehead contour and prevent the support sheet from slipping or shifting during wearing. This stability is crucial to ensure the continuity and stability of oxygen delivery, which helps to improve the treatment effect.

[0041] 3. The design of the second skin-friendly friction layer also facilitates the cleaning and maintenance of the mask. Since this layer usually has a certain waterproof performance, it can be easily wiped with a damp cloth or washed with water to remove dirt and bacteria on the surface. This helps reduce the risk of cross infection and extend the service life of the mask.

[0042] Further, the oxygen mask is made of a transparent material.

[0043] The beneficial effects of the basic solution are: 1. The mask made of transparent material allows medical staff to clearly observe the patient's facial expressions, lip color, breathing status and other important vital signs. This is crucial for timely detection and treatment of potential respiratory problems, and helps to improve the safety and effectiveness of treatment. Especially in emergency situations, medical staff can quickly make judgments and take corresponding measures to protect the patient's life safety.

[0044] 2. Transparent materials usually have better visibility and are easy to clean. This makes the mask more convenient in terms of cleaning and maintenance. Medical staff can easily wipe the surface of the mask with a damp cloth or wash it with water to remove dirt and bacteria, thereby reducing the risk of cross infection.

DETAILED DESCRIPTION

[0049] The following is further described in detail through specific implementation methods:

[0050] Example 1

[0051] Basically as attached Figure 1 , Figure 2 and Figure 3 As shown: an improved high-flow respiratory humidification therapy device oxygen mask, including an oxygen mask 1, the oxygen mask 1 is made of a transparent material, the outer walls of both sides of the oxygen mask 1 are integrally formed with side piston cylinders 2, the side piston cylinders 2 are slidably fitted with side pistons 22, the side pistons 22 are integrally formed with side connecting rods 3 on the side away from the oxygen mask 1, the side connecting rods 3 pass through the outer wall of the side piston cylinder 2 and are slidably fitted with the outer wall of the side piston cylinder 2, the end of the side connecting rod 3 away from the side piston 22 is bonded with a side strap 4, the top outer wall of the oxygen mask 1 is integrally formed with a support component, the support component is used to adjust the longitudinal angle of the oxygen mask 1, the top of the support component is integrally formed with a top piston cylinder 10, the top piston is slidably fitted in the top piston cylinder 10, and the side of the top piston away from the oxygen mask 1 is integrally formed with a top connecting rod 11, the top connecting rod 11 passes through the outer wall of the top piston cylinder 10 and slides with the outer wall of the top piston cylinder 10, the top connecting rod 11 is bonded with a top strap 23 at one end away from the top piston, and the other end of the top strap 23 is detachably connected to a connecting net 6, the connecting net 6 and the side strap 4 are both detachably connected, and length adjusters 17 are installed on the side straps 4 and the top strap 23, the top strap 23 and the side strap 4 are detachably connected to the connecting net 6 through Velcro 5, a flexible layer is laid on the side of the top strap 23 and the side strap 4 close to the patient, an annular trachea 21 is laid on the outer edge of the oxygen mask 1 close to the patient's skin, the annular trachea 21 extends into the support assembly, the side piston cylinder 2 and the top piston cylinder 10 are connected to the annular trachea 21, and the outer periphery of the annular trachea 21 is wrapped with a first skin-friendly layer 7.

[0052] The oxygen supply mask 1 can cover the patient's mouth and nose. The oxygen supply mask 1 is provided with a through hole 26 corresponding to the patient's mouth. A mouth elbow 16 is rotatably connected in the through hole 26. A rubber plug 19 is plugged at one end of the mouth elbow 16 away from the oxygen supply mask 1. An inner fixing ring and an outer fixing ring 18 are integrally formed on the rubber plug 19. The inner fixing ring is used to plug the mouth elbow 16 to fix the rubber plug 19. The outer fixing ring 18 is used to wrap around the outer side of the bottom end of the mouth elbow 16 to receive dirt. A plurality of exhaust holes 15 are provided on the outer side of the bent portion of the mouth elbow 16.

[0053] The oxygen mask 1 is provided with a vent 25 corresponding to the position of the patient's nose, and a nose elbow 14 is rotatably connected in the vent 25, and the nose elbow 14 is connected to the output end of the high-flow respiratory humidification therapy device.

[0054] The specific implementation process is as follows: before the high-flow respiratory humidification therapy device is used for oxygen therapy, the patient is firstly put on the oxygen mask 1 by pasting the side straps 4 and the top strap 23 with the connecting net 6 through the Velcro 5, and the Velcro 5 pasting method makes the oxygen mask 1 flexible to wear, such as connecting the side straps 4 and the connecting net 6 to cover the patient's head and then connecting the top strap 23 and the connecting net 6, or first connecting the top strap 23 and the side strap 4 and then wearing the oxygen mask 1 from the side, and after wearing, the length of the strap is adjusted by the length adjuster 17 to appropriately fix the oxygen mask 1 firmly on the patient's mouth and nose, and the flexible layer on the inner side of the strap can reduce the friction and irritation of the strap to the patient's skin, reduce the sense of binding and make it more comfortable to wear for a long time. At the same time, the first skin-friendly layer 7 wrapped around the periphery of the annular trachea 21 can be closely contacted with the patient's facial skin in accordance with the shape of the oxygen mask 1, on the one hand, reducing the irritation and friction to the skin, and on the other hand, improving the sealing of the oxygen mask 1, preventing oxygen leakage or external air from entering the oxygen mask 1, and ensuring the effect of oxygen therapy.

[0055] After wearing the oxygen mask 1, the medical staff connects the output end of the high-flow respiratory humidification therapy device with the nasal elbow 14 to continuously supply oxygen into the oxygen mask 1. Since the patient is in a supine position most of the time, the rotatability of the nasal elbow 14 means that the oxygen output end does not need to be bent in any direction, avoiding affecting the oxygen supply efficiency. Oxygen enters the oxygen mask 1 from above the patient's nose. After the patient breathes, the waste gas is exhaled downward from the nose, descends to the oral elbow 16 and is discharged from the oxygen mask 1 from the exhaust hole 15, forming an oxygen flow from top to bottom, avoiding the patient from inhaling waste gas and ensuring the treatment effect. The oral elbow 16 can also be rotated, which is convenient for medical staff to adjust the oxygen mask 1, thereby avoiding cleaning dead corners and protecting the life and health of patients. The rubber plug 19 at the end of the oral elbow 16 is convenient for medical staff to remove for some intubation or inspection operations, which enhances the flexibility of the oxygen mask 1 when in use, and the outer fixing ring 18 of the rubber plug 19 can form a cup-shaped structure, which plays a role in carrying the dirt in the oral elbow 16. When the patient has difficulty in moving or has limb inconvenience but needs to cough up or spit out secretions, the patient can conveniently spit on the rubber plug 19 through the oral elbow 16 without having to endure the pain of oxygen mask contamination or the risk of suffocation. The rubber plug 19 has the function of temporarily containing dirt. After that, the medical staff or the patient can easily remove the rubber plug 19 to dump the dirt to avoid contamination of the internal environment of the oxygen mask 1.

[0056] like Figure 1When the patient wears the oxygen mask 1 for a long time, a certain strap may be pulled due to unconscious posture adjustment. At this time, the connecting net 6 is first spread out and laid on the back of the patient's head, forming a tight and firm fit. Some hair passing through the connecting net 6 can increase the fixing strength of the connecting net 6. When one of the straps is pulled, it pulls the connecting rod and piston connected to it to move in the piston cylinder. The air between the piston and the outer wall of the piston cylinder is compressed but does not escape due to the airtightness between the connecting rod and the piston cylinder, forming a pneumatic buffer for the current strap pulling. When the piston moves outward, the gas density between the piston and the annular air pipe 21 decreases, and the atmospheric pressure transmits the thrust to the other two piston cylinder positions through the annular air pipe 21, which is manifested as the pistons in the other two piston cylinders moving toward the oxygen mask 1, thereby tightening the other two straps, improving the fixation of the oxygen mask 1, reducing the possibility of displacement of the oxygen mask 1 caused by the pulling of the straps, and enhancing the safety and airtightness of long-term wearing.

[0057] Example 2

[0058] The difference from the above embodiment is that, as shown in the attached Figure 1 , Figure 2 and Figure 3 As shown: the support assembly includes a support bar 8, a support ring 20 is integrally formed on the top of the support bar 8, a support nut 9 is connected to the ring sleeve on the support ring 20, a support bolt 12 is threadedly matched in the support nut 9, a support sheet 13 is integrally formed on the end of the support bolt 12 away from the support nut 9, a second skin-friendly friction layer 24 is laid on the bottom of the support sheet 13, the side of the support ring 20 away from the support bar 8 is integrally formed with the top piston cylinder 10, and the annular air pipe 21 extends into the support bar 8 and the support ring 20.

[0059] The specific implementation process is as follows: the piston cylinders 2 on both sides and the top piston cylinder 10 can be connected through the support strip 8 and the annular air pipe 21 inside the support ring 20, which plays a role in driving the piston to tighten the strap to fix the oxygen mask 1. When wearing the oxygen mask 1, the support sheet 13 is attached to the forehead, and the second skin-friendly friction layer 24 on the support sheet 13 provides a fixing effect for the support bolt 12 and the oxygen mask 1 at the same time, reducing the possibility of displacement. By rotating the support nut 9, the support ring 20 is lifted and lowered on the support nut 9, and the support strip 8 drives the adjustment of the longitudinal angle of the oxygen mask 1, so that the bottom of the oxygen mask 1 fits the patient's chin better, and the top reduces the pressure on the bridge of the nose, thereby improving the patient's wearing comfort and the air tightness of the oxygen mask 1, and enhancing the therapeutic effect of oxygen ventilation.
