SUMMARY

[0003] To solve the technical problems in the prior art, the utility model provides a breathing mask with oxygen connection and pressure measurement function.

[0004] To achieve the above objectives, this utility model proposes a breathing mask capable of receiving oxygen and measuring pressure, comprising: a sealing pad assembly, a frame assembly, and a curved tube assembly, wherein the sealing pad assembly, frame assembly, and curved tube assembly are detachably connected in sequence; the curved tube assembly includes a curved tube and a cap, the curved tube having a groove, and multiple ventilation slots formed along the outer periphery of the inner side of the groove, a hollow cylinder at the center of the groove, an annular silencer within the groove, and the cap fastened to the groove, the cap having multiple exhaust holes, through which exhaled waste gas is discharged sequentially via the ventilation slots, the annular silencer, and the exhaust holes. By providing multiple ventilation slots on the curved tube and placing the annular silencer within the groove, the waste gas generated by the patient's breathing can be discharged sequentially via the ventilation slots, the annular silencer, and the exhaust holes on the cap, thereby reducing exhaled waste gas noise; simultaneously, the hollow cylinder on the curved tube is used for receiving oxygen and measuring pressure, and the small holes on the hollow cylinder can be opened when necessary to increase exhaust flow and reduce re-inhalation of carbon dioxide. The annular silencer is placed between the recessed part and the cover to guide its installation and limit its position after installation. The annular silencer effectively reduces airflow vibration at the exhaust port on the cover, lowering turbulent noise and making the breathing mask quieter during use.

[0005] As an optional implementation, in the oxygen-connecting and pressure-measuring respirator provided by this utility model, the curved tube assembly further includes a sealing cap, which is fastened onto the snap-on cap, and the cap plug of the sealing cap engages with the hollow cylinder. Normally, the hollow cylinder is covered by the cap plug of the sealing cap. When oxygen connection or pressure measurement is required, the cap plug is opened, and a matching hose can be connected. Alternatively, the cap plug can be opened when necessary to increase exhaust flow and reduce re-inhalation of carbon dioxide.

[0006] As an optional implementation, in the oxygen-connecting and pressure-measuring breathing mask provided by this utility model, the bent tube assembly further includes a bent tube connector. The bent tube connector has an annular boss inside, and the bent tube has an annular concave surface that mates with the annular boss. One end of the bent tube connector is connected to the bent tube, and the other end is used to connect to a breathing support device to deliver breathing gas. By providing the annular boss and the annular concave surface that mates with the annular boss, the bent tube connector can be fixed and installation can be facilitated.

[0007] As an optional implementation, in the oxygen-connecting and pressure-measuring respirator provided by this utility model, the sealing pad assembly includes a sealing pad and a support. The sealing pad is fastened to the support, and the support has a first ventilation hole. The sealing pad can be a flexible component, used to contact the wearer's face and form a seal, having a side that fits in contact with the human face, thus enhancing the user experience.

[0008] As an optional implementation, in the oxygen-connecting and pressure-measuring breathing mask provided by this utility model, the frame assembly includes a frame and a hook. The frame has a raised rib, which engages with a slot on the support for installation. The frame has a second ventilation hole, which connects with the first ventilation hole. The hook fastens onto the frame. The raised rib and matching slot facilitate installation, and the hook facilitates wearing, serving to secure and connect the headband.

[0009] As an optional implementation, in the oxygen-connecting and pressure-measuring breathing mask provided by this utility model, the annular sound-absorbing component is a filter cotton or a noise-reducing mesh, and the thickness of the annular sound-absorbing component is approximately 1-5 mm. Both the filter cotton and the noise-reducing mesh have good air permeability. The thickness of the annular sound-absorbing component should not be too thick, firstly because excessive thickness will reduce gas permeability, thus failing to achieve the exhaust effect, and secondly because excessive thickness will affect the overall weight of the mask.

[0010] As an optional implementation, in the oxygen-connecting and pressure-measuring breathing mask provided by this utility model, the diameter of the exhaust port is 0.6mm to 0.9mm, and the diameter of the exhaust port gradually increases from the inside to the outside along the exhaust direction, which is perpendicular to the wearer's face and outwards. The gradually increasing diameter of the exhaust port along the exhaust direction, in a divergent pattern, facilitates patient ventilation. The exhaust direction, set perpendicular to the wearer's face, ensures that the exhaled air enters the gas chamber and is promptly discharged through the exhaust ports on the frame during use. Furthermore, the divergent exhaust direction helps reduce noise and prevents the air from blowing onto the bedside partner.

[0011] As an optional implementation, in the oxygen-connecting and pressure-measuring breathing mask provided by this utility model, the aperture of the hollow cylinder is 2.0 to 3.0 mm.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In the oxygen-connecting and pressure-measuring breathing mask provided by the present invention, a sealing gasket assembly, a frame assembly, and a bent tube assembly are provided, and the sealing gasket assembly, the frame assembly, and the bent tube assembly are detachably connected in sequence; the bent tube assembly includes a bent tube and a cover, the bent tube is provided with a groove, the inner side of the groove is provided with multiple ventilation slots along the outer periphery, a hollow cylinder is provided at the center of the groove, an annular silencer is provided in the groove, the cover is fastened to the groove, and the cover is provided with multiple exhaust holes, and the exhaled exhaust gas is discharged sequentially through the ventilation slots, the annular silencer, and the exhaust holes. By incorporating multiple ventilation slots on the curved tube and placing an annular silencer within the recessed section, the waste gas generated by the patient's breathing can be expelled sequentially through the ventilation slots, the annular silencer, and the exhaust port on the cover, thereby reducing exhaled noise. Simultaneously, a hollow cylinder is provided on the curved tube for connecting oxygen and measuring pressure. If necessary, the small holes on the hollow cylinder can be opened to increase exhaust flow and reduce re-inhalation of carbon dioxide. This oxygen-connecting and pressure-measuring breathing mask not only effectively improves the problem of exhaust gas blowing on the bedside and reducing noise, thus facilitating patient treatment and improving the comfort of both the patient and their bedside, but also adds oxygen connection and pressure measurement functions to meet more usage needs.

[0013] In addition, the existing breathing mask can be improved by using an annular silencer in the groove. The annular silencer covers the exhaust structure and the multiple air channels contained in the annular silencer can disperse the airflow, making the stream of air disperse into smaller airflows with less turbulence, thereby slowing down the exhaust airflow and greatly reducing the sound when the gas is discharged to the outside environment through the annular silencer, thus reducing noise and preventing the exhaust flow from blowing onto the bed partner.
