Description

Technical Field

[0001] This application relates to the technical field related to respiratory assistance, and particularly to a respiratory mask structure with high comfort. Background Art

[0002] The respiratory mask used in emergency care is an important medical device, mainly used for artificial ventilation. In emergency situations, when the patient's spontaneous breathing ability is limited or lost, the respiratory mask can provide oxygen to maintain the patient's life. The respiratory mask is usually connected to an oxygen cylinder or a ventilator, and oxygen is delivered to the patient's respiratory tract through the mask.

[0003] In emergency care, as an important medical device, the respiratory mask is used very frequently. However, wearing the mask for a long time may cause pressure injuries to the patient's face, which is mainly caused by the continuous pressure generated by the fixation and straps of the mask and the friction between the mask and the skin. Therefore, in current emergency care, there is a need for a respiratory mask with high comfort. Utility Model Content

[0004] This application proposes a respiratory mask structure with high comfort, which has the advantage of being able to change the extrusion part in real time to solve the problem of continuous pressure generated between the mask and the face mentioned in the above background art.

[0005] To achieve the above object, this application adopts the following technical solution: A respiratory mask structure with high comfort, including: a mask body, with a sponge strip fixedly installed on the back to prevent direct contact between the mask body and the user's face; a mounting post, fixedly connected to the surface of the mask body, and a connecting rod is fixedly connected to the outside of the mounting post; an inner pressure ring, fixed at the end of the connecting rod, and a guide rail frame is movably installed on the outside of the inner pressure ring; a connecting sliding ring, coaxial with the inner pressure ring, fixedly connected to the outside of the guide rail frame; an outer pressure ring, coaxial with the inner pressure ring, movably installed on the outside of the connecting sliding ring; a buckle ring, arranged on the back of the mask body, and the buckle ring is connected to the outer pressure ring through a pull rope.

[0006] Further, the inner pressure ring is in a circular ring shape, and the inner diameter of the inner pressure ring is equal to the maximum length of the mask body.

[0007] Further, the guide rail frame makes a circular motion with the inner pressure ring as the path and the center of the inner pressure ring as the rotation point.

[0008] Further, an air delivery pipe is fixedly installed on the surface of the mounting post.

[0009] Furthermore, an air inlet box is fixedly installed on the surface of the outer pressure ring. A transmission shaft is movably installed inside the air inlet box. A transmission gear is fixedly installed at the bottom end of the transmission shaft. A tooth seat meshing with the external teeth of the transmission gear is arranged on the outer side of the connecting slip ring. A wind blade located in the inner cavity of the air inlet box is fixedly installed on the side of the transmission shaft. One end of the air delivery pipe is connected to one side of the air inlet box. An air inlet pipe is fixedly installed on the other side of the air inlet box, and the air inlet pipe is connected to the air tank.

[0010] Furthermore, the air inlet pipe supplies gas to the air delivery pipe through the inner cavity of the air inlet box, and the gas passing through the inner cavity of the air inlet box will drive the wind blade to rotate synchronously.

[0011] The utility model has the following beneficial effects:

[0012] A breathing mask structure with high comfort provided by this application aims to improve the wearing comfort of patients and reduce the skin pressure problems that may be brought about by long-term use. The structural characteristics of this mask lie in the setting of its inner pressure ring and outer pressure ring, as well as their innovative connection through the guide rail frame.

[0013] When a patient wears this mask, the guide rail frame can rotate flexibly around the inner pressure ring. This rotation not only makes the pressure exerted by the guide rail frame on the mask body show a circular change, but also further causes the force exerted by the mask body on the face to show a circular change. This design makes the pressure distribution of the mask on the face more uniform, avoiding the discomfort and potential skin problems caused by long-term continuous squeezing of the same part.

[0014] Compared with the traditional mask design, this mask structure is more in line with the ergonomic principle and can better adapt to patients with different facial shapes and sizes. In addition, its circularly changing pressure distribution not only improves the wearing comfort, but also helps to reduce the friction and irritation of the mask on the facial skin, thus significantly reducing the risk of pressure injury.

[0023] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0024] Embodiment 1

[0025] Please refer to Figure 1 and Figure 2 It can be seen that the overall shape of the mask body 1 is triangular, so that it can better fit on the user's face, thereby covering the user's nose and mouth. A whole circle of sponge strips 100 is fixedly installed on the back of the mask body 1, so that the sponge strips 100 are located between the face and the mask body 1, thereby buffering between the mask body 1 and the face and preventing the mask body 1 from directly contacting the user's face.

[0026] The surface of the mask body 1 is fixedly connected with outwardly protruding mounting posts 101, and the outer sides of the mounting posts 101 are fixedly connected with connecting rods 6. At the same time, the ends of the connecting rods 6 are fixedly installed with inner pressure rings 4. From Figure 1 it can be seen that the inner pressure ring 4 is circular in shape, and a guide rail frame 12 is movably installed on the outer side of the inner pressure ring 4. The guide rail frame 12 can perform circular motion with the outer side of the inner pressure ring 4 as the path and the center of the inner pressure ring 4 as the rotation point.

[0027] Combined with Figure 2 and Figure 3 it can be clearly seen that the outer side of the guide rail frame 12 is fixedly connected with a connecting slip ring 11 coaxial with the inner pressure ring 4, and an outer pressure ring 5 coaxial with the inner pressure ring 4 is movably installed on the outer side of the connecting slip ring 11. Thus, the guide rail frame 12 can perform circular motion with the outer side of the inner pressure ring 4 and the inner side of the outer pressure ring 5 as the path.

[0028] Regarding the fixation of the outer pressure ring 5, thusFigure 2 It can be clearly seen that a buckle 3 is provided on one side of the back of the mask body 1, and the buckle 3 is connected to the outer pressure ring 5 through a drawstring 2. Thus, during the wearing process of the mask body 1, the buckle 3 is buckled on the back of the head of the user, and the mask body 1 is closely attached to the mouth and nose of the user.

[0029] From Figure 1 it can be seen that an air delivery pipe 10 is fixedly installed on the surface of the mounting post 101, and thus air flow is input into the interior of the mask body 1 through the air delivery pipe 10 to facilitate the breathing of the user.

[0030] In the actual application process, when the user wears the mask body 1, since the main force for the mask body 1 to adhere to the face of the patient is the extrusion of the face by the guide rail frame 12, this force relies on the drawstring 2 to pull the outer pressure ring 5 to further move the guide rail frame 12 towards the face. From Figure 1 it can be seen that the inner diameter of the inner pressure ring 4 is approximately the same as the maximum length of the mask body 1, so that the guide rail frame 12 is always located outside the mask body 1. By changing the position of the guide rail frame 12, the position where the guide rail frame 12 presses on the outer pressure ring 5 changes. That is, the pressing force is relatively large at the part closer to the guide rail frame 12, and relatively small at the position far from the guide rail frame 12. Combining the above, the guide rail frame 12 can rotate. Thus, during application, by manually changing the position of the guide rail frame 12, the pressing focus of the mask body 1 on the face can be adjusted adaptively to avoid local extrusion of the face by the mask body 1 for a long time.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, for further improvement, please refer to Figure 1 、 Figures 3 - 5 it can be seen that an air inlet box 7 is fixedly installed on the surface of the outer pressure ring 5. A transmission shaft 9 is movably installed inside the air inlet box 7. A transmission gear 13 is fixedly installed at the bottom end of the transmission shaft 9. A tooth seat meshing with the external teeth of the transmission gear 13 is arranged on the outer side of the connecting slip ring 11. The tooth seat is circular. Thus, when the transmission gear 13 rotates, the connecting slip ring 11 can be driven to rotate synchronously.

[0033] A wind blade 14 located inside the air inlet box 7 is fixedly installed on the side of the transmission shaft 9. From Figure 5 it can be clearly seen that one end of the air delivery pipe 10 is connected to one side of the air inlet box 7, and an air inlet pipe 8 is fixedly installed on the other side of the air inlet box 7. According to the connection between the air inlet pipe 8 and the gas tank, gas is supplied into the air delivery pipe 10 through the inner cavity of the air inlet box 7 via the air inlet pipe 8. During the flow of the gas through the inner cavity of the air inlet box 7, the wind blade 14 will be driven to rotate synchronously, so that the transmission shaft 9 drives the transmission gear 13 to rotate.

[0034] In the actual application process, when the user wears the mask body 1, gas is conveyed to the air delivery pipe 10 through the air inlet pipe 8, and the gas is transmitted to the inside of the mask body 1 through the air delivery pipe 10, so as to supply the gas for the patient to breathe.

[0035] When the air flow passes through the inner cavity of the air inlet box 7, it will synchronously drive the wind blade 14 to rotate, so that the wind blade 14 drives the transmission gear 13 to rotate synchronously through the transmission shaft 9. The transmission gear 13 will make the connected slip ring 11 meshed with it rotate synchronously. The rotation of the connected slip ring 11 will also cause the guide rail frame 12 to perform a circular periodic rotation with the outer side of the inner pressure ring 4 as the path. Therefore, it can be known that when the guide rail frame 12 performs a periodic circular motion, the pressing force of the guide rail frame 12 on the inner pressure ring 4 will also be periodically changed, which will also cause the pressing force of the inner pressure ring 4 on the mask body 1 to be periodically changed, resulting in the mask body 1 pressing on the face in a circular manner. Since the key point of the pressing force is constantly changing, it avoids the phenomenon of pressure injury caused by the mask body 1 continuously pressing on the user's face locally.
