Description

TECHNICAL FIELD

[0001] The utility model relates to medical instrument equipment field, especially a breathing mask. BACKGROUND

[0002] The breathing mask is an important medical equipment, which is connected with the ventilation pipeline of the breathing machine, can help the human body to maintain normal breathing, increase the lung ventilation volume and improve the respiratory function.

[0003] The exhaust holes of the breathing mask are an important part in design, which ensure that the carbon dioxide in the mask can be smoothly discharged, and avoid the patient inhaling the carbon dioxide he exhales, which is very important for preventing carbon dioxide retention, therefore, the exhaust holes need to be cleaned regularly to ensure that they are unobstructed.

[0004] The existing breathing mask is basically integrated with the mask body, that is, the exhaust holes are integrally formed on the support frame of the mask body, when the exhaust holes need to be cleaned, the whole support frame part of the mask body needs to be disassembled, which is relatively cumbersome, and the exhaust holes cannot be disassembled and cleaned independently, which brings great inconvenience to the user.

[0005] Therefore, it is necessary to provide a breathing mask which can disassemble and clean the exhaust holes independently. SUMMARY

[0006] The utility model aims at overcoming the above-mentioned prior art, and provides a breathing mask.

[0007] According to one aspect of the utility model, a breathing mask is provided, which comprises:

[0008] The mask body is provided with a support frame and an elbow pipe for connecting the ventilation pipeline of the breathing machine, one end of the elbow pipe is inserted and fixed in the support frame, and a protruding buckle is arranged on the outer wall of the elbow pipe; and

[0009] The exhaust ring is provided with exhaust holes, and the inner wall of the exhaust ring is provided with a notch, the exhaust ring is sleeved on the elbow pipe, the protruding buckle is clamped in the notch, and the outer wall of the exhaust ring and the inner wall of the support frame are between the elbow pipe.

[0010] The breathing mask of the utility model, the bend pipe is connected with the ventilation pipeline of the breathing machine, the breathing machine can provide breathing support to the patient through the bend pipe, the exhaust hole is independently arranged on the exhaust ring, the exhaust ring is installed between the outer wall of the bend pipe and the inner wall of the support frame of the mask body, when the exhaust hole needs to be cleaned, the exhaust ring is pulled out from the inner wall of the support frame, then the exhaust ring is pulled outwards from the bend pipe, the protruding buckle on the bend pipe is withdrawn from the gap on the exhaust ring, at this time, the exhaust ring can be detached from the bend pipe for independent cleaning, after cleaning, the exhaust ring is sleeved on the bend pipe, and it is ensured that the gap on the exhaust ring is aligned with the protruding buckle on the bend pipe, then the exhaust ring is pressed and combined between the outer wall of the bend pipe and the inner wall of the support frame, the exhaust ring is very convenient to assemble and disassemble, so that the exhaust hole on the exhaust ring can be independently and quickly cleaned, and great convenience is brought to the user.

[0011] Further, the exhaust ring comprises an inner ring wall, an outer ring wall and an inclined wall, the end of the inner ring wall is connected with the end of the outer ring wall through the inclined wall, the exhaust hole is arranged on the inclined wall, the gap is arranged on the inner ring wall, the inner ring wall is sleeved on the bend pipe, and the outer ring wall abuts against the inner wall of the support frame.
