Effect, can effectively fix sputum aspirator tube；The external sputum aspirator of sputum aspirator tube, so that the secretion of patients with respiratory tract be inhaled
Out.
Embodiment 6
A kind of oropharynx air-breather, unlike the first embodiment: the teeth pad 4 prolongs along the length direction of the mask 2
It stretches, and the length of the teeth pad 4 is less than the length of the mask 2.Mask can protect part face in the present invention,
Teeth pad needs the occlusion of patient teeth, and therefore, the length of teeth pad needs to be less than the length of mask, and the length of teeth pad needs
It is less than the half length of tooth, patient teeth needs to sting respectively on the upper and lower end face of teeth pad, to fixing pipe, human body
Soft tissue and face carry out multiple protective, increase the comfort of patient, mitigate the pain of patient.
As shown in fig. 6, mask 2 described in the present embodiment includes pedestal 201, two fixed parts 202 and two adjustment portions 203, institute
It states pedestal 201 to be sheathed on outside the fixing pipe 1, two fixed parts 202 are respectively arranged on the two sides of the pedestal 201, and along institute
The diameter of axle direction for stating fixing pipe 1 is symmetrical arranged, and is equipped on an each side end face of the fixed part 202 far from the pedestal 201
First sliding groove 204, each adjustment portion 203 are equipped with and the first sliding groove 204 on a side end face of the fixing pipe 1
First sliding block 205 of corresponding matching connection.
Each teeth pad 4 includes fixed block 401 and adjusting block 402 in the present embodiment, and each fixed block 401 is distinguished
It is connected on two fixed parts 202 of the mask 2, and on the side end face on each fixed block 401 far from the fixing pipe 1
It is equipped with second sliding slot 403, is equipped on a side end face of the fixing pipe 1 on each adjusting block 402 and described the
Second sliding block 404 of two sliding slots, 403 corresponding matching connection.
Since the age of patient is different, the size of the teeth pad and mask that need is not also identical, and therefore, teeth pad is divided into
Pedestal, fixed part and adjustment portion, teeth pad are divided into fixed block and adjusting block, can according to need adjustment portion being connected to fixed part
On, adjusting block is connected on fixed block, to adjust the size of mask and teeth pad, is not only simple in structure, it is easy to use, also
The diversity for increasing function, has saved manufacturing cost；And it is possible to which setting the identical part of two sizes for pedestal passes through spiral shell
It tethers and connects, similar to the structure of clip, adjusted according to the size of fixing pipe, fixing pipe can be detachably connected with mask, root
Fixing pipe is replaced according to needing, and stretching structure can be set into fixing pipe, to carry out adjustment length.
Embodiment described above is only that the preferred embodiment of the present invention is described, not to the scope of the present invention into
Row limits, and without departing from the spirit of the design of the present invention, those of ordinary skill in the art make technical solution of the present invention
Various changes and improvements out, should fall within the scope of protection determined by the claims of the present invention.
