Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to a ventilator mask. Background Art

[0002] With the increase in global respiratory diseases, the demand for ventilator devices and their accessories, especially ventilator masks, is continuously rising. The ventilator mask is a key interface between the patient and the ventilator, and its design quality directly affects the effective transmission of gas, the treatment effect, and the comfort of the wearer. The existing ventilator mask technologies cover from basic silicone masks to more advanced masks with filtration systems, and the design focus aims to optimize the sealing performance, comfort, and breathing resistance of the mask. However, despite the many improved designs on the market, the existing technologies still fail to fully meet the needs of different user groups, especially in the context of long-term wearing.

[0003] Although the existing ventilator masks can provide effective breathing support to a certain extent, they have obvious deficiencies in terms of user comfort, adaptability, and ease of use. For example, many masks only offer limited size options and cannot adapt to users with different face shapes, resulting in discomfort or gas leakage during wearing and affecting the treatment effect. In addition, long-term wearing may also cause facial indentations, skin irritation, or even injury.

[0004] For example, a ventilator mask with the patent application number CN202320072138.7 discloses that "it includes a mask body, an air inlet interface is arranged at the lower end of the mask body, an air inlet pipe is connected to the lower end of the air inlet interface, an air outlet pipe is arranged at the upper end of the air inlet interface, a one-way valve is arranged in the air outlet pipe, a three-pronged bracket is connected to the mask body through a pivot, a fixing belt perforation is arranged at the end of the three-pronged bracket, a mask fixing belt is inserted into the fixing belt perforation, a U-shaped cushion is sleeved on the lower edge of the mask body, the U-shaped cushion includes a silicone pad body, a U-shaped card slot is arranged on the silicone pad body, a chin lining part is arranged at the lower end of the silicone pad body, and cheek lining parts are arranged at the left and right ends of the silicone pad body. A detachable U-shaped cushion is arranged at the lower edge of the ventilator mask, which can be installed on the ventilator mask when used by elderly patients, so as to pad the ventilator mask and the patient's chin and cheek parts, avoid air leakage of the ventilator mask, improve the sealing performance, and also avoid the generation of pressure sores, which is worthy of promotion." Although the above structure can achieve the sealing effect on the human face, due to the different facial conditions of each person, the above technical solution cannot change the size of the mask or the height of the cushion at the part in contact with the face; therefore, for some patients with different facial sizes, when using it, it will cause strong extrusion of the cushion at the local part. Although the cushion has elasticity to meet the fit between the cushion and the face, long-term wearing will cause strong extrusion of the local face, resulting in more serious facial indentations and other problems.

[0005] To solve the above problems, we provide a ventilator mask that can adjust the distance between the sealing ring on the mask body and the mask body to avoid serious indentations on the face. Utility Model Content

[0006] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a ventilator mask.

[0007] The purpose of the utility model is achieved as follows: A ventilator mask includes a mask body, an air inlet end and an exhaust end are provided on the mask body, a sealing ring is connected to the inner edge of the mask body, a connecting rubber strip is connected below the sealing ring, a circular placement groove is provided at the inner edge of the mask body, and the connecting rubber strip is located in the placement groove and can move up and down.

[0008] Furthermore, a moving groove is provided in the mask body below the placement groove, a moving rubber strip that can move up and down is provided in the moving groove, and the moving rubber strip is fixedly connected to the connecting rubber strip.

[0009] Furthermore, a plurality of magnets are evenly arranged in the moving rubber strip, and multiple rows of magnetic strips are evenly arranged in the moving groove, and the magnets and the magnetic strips attract each other.

[0010] Furthermore, the sealing ring, the moving rubber strip, and the connecting rubber strip are all made of elastic and stretchable materials.

[0011] Furthermore, the exhaust end includes an exhaust pipe, and a one-way valve is provided in the exhaust pipe.

[0012] Furthermore, the one-way valve includes a sealing plate that moves back and forth in the exhaust pipe, and an exhaust port is provided on the side of the exhaust pipe.

[0013] Furthermore, the outer end of the exhaust pipe is threadedly connected with an adjusting cover, a limiting cylinder is fixedly provided on the inner side of the adjusting cover, a guide rod that can move back and forth is provided in the limiting cylinder, a spring is provided between the guide rod and the limiting cylinder, and the rear end of the guide rod is fixedly connected to the sealing plate.

[0014] Furthermore, a retaining ring is provided in the exhaust pipe, and the sealing plate is located in front of the retaining ring.

[0015] When the utility model is in use, the device is fixed on the user's face through a strap. Since everyone's face is different, in order to avoid reducing the gap between the mask and the face during wearing, a seal ring that can move up and down is provided to reduce the gap between the face and the mask. When adjusting the seal ring, press the mask towards the face (or press the seal ring towards the mask body). During the pressing process, the seal ring at the pressing position moves towards the mask body, and the connecting rubber strip below the seal ring drives the moving rubber strip to move downward, so that the moving rubber strip moves towards the bottom of the moving groove. While the moving rubber strip moves downward, the corresponding magnet on the moving rubber strip at the pressing position adsorbs on the magnetic strip below, realizing the limit of the moving rubber strip and preventing the moving rubber strip from moving upward, thereby changing the position of the seal ring and making the seal ring fit the face as a whole.

[0016] The device adopts the structure of a seal ring that can move up and down, which can make the seal ring fit the face more closely and reduce the gap between the two. At the same time, since the seal ring is limited and fixed by the magnetic strip and the magnetic sticker after moving downward, (when not in use, the seal ring can also be pulled outwards to reset the seal ring, which is convenient for reuse or adjusting the wearing position of the face, and then adjusting the gap between the seal ring and the face again), so the pressed seal ring will not reset and cause strong extrusion to the face. The seal ring is made of elastic and telescopic material, which can make it more comfortable to wear. The adjustable seal ring can realize the size matching between the seal ring and the face, and avoid the occurrence of a situation where the local extrusion force is too large when the seal ring fits the face.

[0017] A one-way valve is provided. When exhaling outwards, the air pressure inside the mask is too high, driving the sealing plate to move outwards. At this time, the spring is compressed. When the sealing plate passes over the exhaust hole, the gas is discharged outwards through the exhaust hole. When the internal air pressure is equal to the external air pressure or when inhaling, the sealing plate is reset under the elastic force of the spring, and the sealing plate fits with the retaining ring to seal the exhaust end, preventing external gas from entering the mask interior. At the same time, the smoothness of the exhaust can be adjusted as needed, that is, rotate the adjusting cover, and the adjusting cover drives the spring to stretch and contract. When the adjusting cover moves outwards, the extrusion force of the spring on the sealing plate becomes smaller, and the exhaust is smoother. A smaller air pressure inside the mask can push out the sealing plate, and the gas is discharged through the exhaust hole.

[0018] Beneficial effects: This application can fix the mask body to the face, and at the same time, the gap between the face and the seal ring can be adjusted through the adjustment of the seal ring. And since the seal ring is limited and fixed by the magnetic strip and the magnetic sticker after moving downward, the pressed seal ring will not reset and cause strong extrusion to the face. The seal ring is made of elastic and telescopic material, which can make it more comfortable to wear. Description of the Drawings

[0027] Example 1, as Figure 1 —6 shows, the purpose of the present utility model is realized as follows: A ventilator mask includes a mask body 1, an air inlet end and an exhaust end 5 are arranged on the mask body 1, a sealing ring 2 is connected to the inner edge of the mask body 1, a connecting rubber strip 14 is connected below the sealing ring 2, a circular placement groove is formed at the inner edge of the mask body 1, and the connecting rubber strip 14 is located in the placement groove and can move up and down.

[0028] A moving groove 18 is formed in the mask body 1 below the placement groove, a moving rubber strip 16 is arranged in the moving groove 18 and can move up and down, and the moving rubber strip 16 is fixedly connected to the connecting rubber strip 14. A plurality of magnets 15 are uniformly arranged in the moving rubber strip 16, and multiple rows of magnetic strips 17 are uniformly arranged in the moving groove 18, and the magnets 15 and the magnetic strips 17 attract each other. The sealing ring 2, the moving rubber strip 16 and the connecting rubber strip 14 are all made of elastic and stretchable materials to cooperate with the overall technical solution to realize the up and down movement of the sealing ring 2.

[0029] The exhaust end 5 includes an exhaust pipe 6, and a one-way valve is arranged in the exhaust pipe 6. The one-way valve includes a sealing plate 11, the sealing plate 11 moves back and forth in the exhaust pipe 6, and an exhaust port 7 is formed on the side of the exhaust pipe 6.

[0030] The outer end of the exhaust pipe 6 is threadedly connected with an adjusting cover 4. A limiting cylinder 8 is fixedly arranged on the inner side surface of the adjusting cover 4. A guide rod 12 is arranged in the limiting cylinder 8 so as to be movable back and forth. A spring 9 is arranged between the guide rod 12 and the limiting cylinder 8. The rear end of the guide rod 12 is fixedly connected with a sealing plate 11. A retaining ring 10 is arranged in the exhaust pipe 6. The sealing plate 11 is located on the front side of the retaining ring 10. A rotating plate 13 is arranged in the limiting cylinder 8 so as to be rotatable. The rotating plate 13 is fixedly connected with the spring 9, and the other end of the spring 9 is fixedly connected with the guide rod 12.

[0031] A gas filter screen is arranged at the exhaust port 7. The gas filter screen can be set as required to filter some harmful gases and the like in the discharged gas.

[0032] When the utility model is in use, the device is fixed on the user's face through the strap 3. Since everyone's face is different, in order to avoid reducing the gap between the mask and the face during wearing, a movable sealing ring 2 is provided to reduce the gap between the face and the mask. When adjusting the sealing ring 2, press the mask towards the face (or press the sealing ring 2 towards the mask body 1). During the pressing process, the sealing ring 2 at the pressing part moves towards the mask body 1, and the connecting rubber strip 14 below the sealing ring 2 drives the movable rubber strip 16 to move downwards, so that the movable rubber strip 16 moves towards the bottom of the moving groove 18. While the movable rubber strip 16 moves downwards, the corresponding magnet 15 on the movable rubber strip 16 at the pressing part adsorbs on the lower magnetic strip 17 to realize the limitation of the movable rubber strip 16 and prevent the movable rubber strip 16 from moving upwards, thereby changing the position of the sealing ring 2 and making the sealing ring 2 fit the face as a whole.

[0033] The device adopts the structure of the movable sealing ring 2, which can make the sealing ring 2 fit the face more closely and reduce the gap between the two. At the same time, since the sealing ring 2 is limited and fixed by the magnetic strip 17 and the magnetic sticker after moving downwards (when not in use, the sealing ring 2 can also be pulled outwards to reset the sealing ring 2, which is convenient for reuse or adjusting the wearing position of the face, and then adjusting the gap between the sealing ring 2 and the face again), the pressed sealing ring 2 will not reset to cause strong extrusion to the face. The sealing ring 2 is made of elastic and telescopic material, which can make the wearing more comfortable.

[0034] A one-way valve is provided. When exhaling outwards, if the air pressure inside the mask is too high, it drives the sealing plate 11 to move outwards. At this time, the spring 9 is compressed. When the sealing plate 11 passes over the exhaust hole, the gas is discharged outwards through the exhaust hole. When the internal air pressure is equal to the external air pressure or when inhaling, the sealing plate 11 is reset under the elastic force of the spring 9, and the sealing plate 11 fits with the retaining ring 10 to seal the exhaust end 5, preventing external gas from entering the inside of the mask. At the same time, the smoothness of the exhaust can be adjusted as needed, that is, by rotating the adjusting cover 4. The adjusting cover 4 drives the spring 9 to expand and contract. When the adjusting cover 4 moves outwards, the extrusion force of the spring 9 on the sealing plate 11 becomes smaller, and the exhaust is smoother. A relatively small air pressure inside the mask can push out the sealing plate 11, and the gas is discharged through the exhaust hole.
