breathing mask

Abstract

A breathing mask comprises a support unit, a mask unit, an adjusting unit, a connecting unit and a headband unit. The support unit comprises a forehead fixing support and an extending frame. The mask unit comprises a cover frame and a mask pad; the adjusting unit comprises an adjusting sheet arranged at the upper end of the cover frame and an inserting pin arranged on the extending frame; the connecting unit comprises pivoting portions located below left and right sides of the extending frame, pivoting rods located below the left and right sides of the cover frame and buckle seats located below the left and right sides of the extending frame; the headband unit comprises a band and a pair of bucklers. The connecting unit is capable of achieving the double purposes of pivoting the support unit and the mask unit and connecting the headband unit and the support unit, the proper tightness of the headband unit can be maintained through the position of the connecting unit, and the effects of facilitated usage and simple appearance can be achieved.

Description

technical field [0001] The invention relates to a medical device, in particular to a breathing mask. Background technique [0002] The breathing mask is used for treating sleep apnea, and at least one mask body is designed to fit over a patient's nose, or to fit over a patient's nose and mouth. Air or other breathable gas can be supplied to the mask body through a duct through a compressor. [0003] The breathing mask includes a rigid frame, and a relatively soft mask body located on the frame. The mask body can be comfortably attached to the patient's nose or around the nose and mouth. [0004] The breathing mask needs to be worn on the patient's nose or nose and mouth through a headband. Usually, some connectors are used to connect the headband to the frame so that the breathing mask can be fixed on the patient's head. Such as figure 1 (US6374826 figure 1 ), produced by the Australian company Resmed Limited Series of breathing masks. The headband 100 used in this pr...

Problems solved by technology

[0007] like image 3 , 4 , is a technology that a mask unit 310 can pivot relative to a bracket unit 320 to better conform to the shape of the patient's face, thereby improving comfort. In the aforementioned patent, a headband 330 is fixed on the bracket unit 320. When the mask When the unit 310 pivots relative to the bracket unit 320, it is mainly to adjust the height position of the patient's nose bridge, that is to say, the position close to the patient's body is less likely to change and can remain compliant, which makes the mask unit 310 relative to the patient. After the bracket unit 320 is adjusted, it is not necessary to adjust the tightness of the headband 330. However, another disadvantage of the previously disclosed patent is that the structure 340 pivotally connecting the mask unit 310 and the bracket unit 320 is relatively large, and needs to increase the volume downward, so that the overall The volume of the breathing mask cannot be reduced, which does not conform to the trend of lightness, thinness and shortness, and the disadvantage of the previously disclosed patent is that the combination of the headband 330 and the bracket unit 320 is time-consuming, and the headband 330 needs to be passed around the hole of the bracket unit 320 and fixed Fixed, not suitable for busy hospital ecology

[0008] Looking at the above two cases, each has its advantages and disadvantages. However, due to the large structural differences between the two cases of the previously disclosed patent, it is impossible to obtain the best of both worlds by simply improving one of the cases. Therefore, in order to improve the deficiencies in the previously disclosed patent , retaining and enhancing new advantages requires overall re-improvement and detailed design, and this goal is the research and development focus of related industries
