Detailed Description

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and therefore are only used as examples, and the protection scope of the present invention is not limited thereby.

Referring to fig. 1 to 4, the present invention provides an oxygen mask, which includes a mask body 100, a fixing band 200 and a cushion 300.

Specifically, the mask body 100 is a conventional respirator mask body 100 in the prior art. The number of the fixing bands 200 is two, and the two fixing bands 200 are symmetrically disposed at the left and right sides of the cover body 100. In use, the securing strap 200 may be selected to be a band with elasticity, which facilitates wearing and increases comfort.

There are two cushions 300, and the two cushions 300 are respectively connected to the two fixing belts 200. An arc notch 310 is formed on one side of the soft cushion 300. The cushion 300 can be worn over the ear through the arcuate notch 310. The arc-shaped gap 310 is used for using the shape of the auricle, two channels are oppositely formed in the soft cushion 300, and two ends of the two fixing straps 200 can respectively pass through the channels in a sliding manner and then are connected with the cover body 100.

When the oxygen mask is used, the mask body 100 is covered on the face, the two soft pads 300 are pulled, the two soft pads 300 are sleeved on the ears, and then the whole oxygen mask is worn. The oxygen mask is not worn on the head, so that pressure sores on the scalp are avoided; meanwhile, because the two fixing bands 200 are fixed on ears, head raising is not needed in the wearing process, the operation convenience is improved, the cushion 300 places the fixing bands 200 to press auricles, and the comfort level of a user is improved.

In particular, the soft pad 300 may be a silicone pad. The silica gel pad has good skin affinity, and further improves the comfort of patients.

In a preferred embodiment, the oxygen mask further comprises an adjustment assembly 400, wherein the adjustment assembly 400 is disposed on the fixing strap 200 for adjusting the length between the fixing strap 200 and the mask body 100.

Specifically, the adjustment assembly 400 includes a housing 410, an inner card 420, and a resilient member 430. The outer case 410 is a hollow case, and two through holes 411 are formed in the outer case 410 to extend from the top to the bottom thereof. The side wall of the outer shell 410 is provided with an operation hole communicated with the inner cavity thereof, the inner card 420 is arranged in the inner cavity of the outer shell 410 through the elastic member 430, and one end of the inner card 420 can slidably penetrate out of the operation hole under the natural state of the elastic member 430. In particular implementations, the resilient member 430 may preferably be a spring. Two through holes 421 are formed in the inner card 420, the two through holes 421 are used in one-to-one correspondence with the two through holes 411 and are partially staggered, the end portion of the inner card 420 is pressed from the outer side, the inner card 420 can slide along the operation hole until the two through holes 421 are aligned with the two through holes 411 respectively, and two ends of the fixing band 200 can slide through the two through holes 421 and then respectively penetrate through the two channels to be connected with the cover body 100.

In a normal state, under the action of the elastic member 430, the two through holes 421 are respectively used with the two through holes 411 one by one and partially staggered, so that the fixing band 200 can be clamped, and the fixing band 200 is prevented from arbitrarily sliding; when the length of fixed band 200 needs to be adjusted, press earlier and move interior card 420, interior card 420 slides along the handle hole, align with two perforation 411 respectively until two through-holes 421, fixed band 200 is in natural state this moment, then can pull the length between fixed band 200 adjustment fixed band 200 and the cover body 100, reach the length that needs after, loosen interior card 420, under the effect of elastic component 430, two through-holes 421 and two perforation 411 resume the looks staggered position, die fixed band 200, make cover body 100 and facial laminating better.

The specific use mode of the oxygen mask is as follows:

when the oxygen mask is used, the mask body 100 is covered on the face, then the two soft pads 300 are pulled, the two soft pads 300 are sleeved on the ears, and the whole oxygen mask is worn.

When finding the distance overlength or the time of short between fixed band 200 and the cover body 100, press earlier and move interior card 420, interior card 420 slides along the handle hole, align with two perforation 411 respectively until two through-holes 421, fixed band 200 is in natural state this moment, then can pull fixed band 200 and adjust the length between fixed band 200 and the cover body 100, after reaching required length, loosen interior card 420, under the effect of elastic component 430, two through-holes 421 and two perforation 411 resume the phase error position, establish the fixed band 200 card again and fix.

The oxygen mask is not worn on the head, so that pressure sores on the scalp are avoided; meanwhile, because the two fixing bands 200 are fixed on the ears, the head does not need to be raised in the wearing process, and the operation convenience is improved. Cushion 300 prevents securing strap 200 from compressing against the pinna, improving comfort to the user. The adjusting assembly 400 is disposed on the fixing band 200, and the adjusting assembly 400 is used for adjusting the length between the fixing band 200 and the mask body 100, so that the mask body 100 can be better attached to the face.

The above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that: the technical solutions described in the foregoing embodiments may still be modified, or some or all of the technical features may be equivalently replaced; such modifications and substitutions do not substantially depart from the scope of the embodiments of the present invention, and are intended to be covered by the claims and the specification.
