The nasal mask used in sleeping has the advantages that the nasal mask is novel in structure, the size of the mask is greatly decreased, comfortable sleeping is obtained while good mouth and nose breathing of a patient can be kept, and meanwhile the mask does not displace due to turning and the like during sleeping.
Description
Technical field
The present invention relates to a kind of medical apparatus and instruments, particularly a kind of sleep nose cup.
Background technology
OSA (obstructive sleep apnea) patient can occur during sleeping mouth, nasal airflow stop circulation reaching 10 seconds or
For more time, and with degradation symptom under blood oxygen saturation, generally, patient's attack times every night reaches more than 30 times, can draw
Play many serious complication, cause patient daytime drowsiness, often fall asleep unconsciously between talking, hypomnesis, note
Power can not be concentrated, work efficiency drop, also can be in a bad mood and the change of behavior.Restless, dreaminess, the enuresis, sexual impotence, morning play headache
Deng.Prior art, by using nose cup, face shield etc. to cover in face when patient falls asleep, supplies for its Continuous aeration in sleep procedure
Oxygen, thus in its sleep procedure, ensure the circulation of its mouthful, nasal airflow, it is to avoid asphyxia.But existing respiratory surface cover body
Long-pending relatively big, generally the mouth and nose of patient are all covered, although ensure that mouth, BITONG gas, it is to avoid asphyxia, but, face shield
Volume is relatively big, generally by elastic cord etc., face shield is fixed on head, it is difficult to ensure that face shield will not occur position in sleep procedure
Move, simultaneously because volume also can be made troubles for sleep relatively greatly, great discomfort may be brought.
Summary of the invention
The goal of the invention of the present invention is: for the problem of above-mentioned existence, it is provided that a kind of novel structure, greatly reduces face shield
Volume, while ensureing that patient can keep the ventilation of good mouth, nasal airflow, it is thus achieved that comfortable sleep, ensures face shield simultaneously
The sleep nose cup will not being subjected to displacement because of rolling in bed etc..
The technical solution used in the present invention is as follows:
A kind of sleep nose cup, including support, the two ends of described support have been respectively fixedly connected with rhinarium, and described rhinarium sets
Having breather, described breather surface to be covered with filter membrane, the thickness of described filter membrane is 0.7mm, and described filter membrane is by cohering and ventilation
Pipe is connected, and described breather is made up of elastomeric material, described rhinarium and internal stent hollow, described breather and rhinarium and support
Internal connection, described support is fabricated from a flexible material, and described internal stent is provided with sizing iron wire.
Owing to have employed technique scheme, breather is inserted in nasal meatus, then become to be suitable for the shape of nose by support-folding
Shape, is shaped by sizing iron wire, can be ensured that breather remains in nasal meatus during sleeping such that it is able to continued
Stable provides gas to circulate for patient, it is to avoid asphyxia, and the gas circulated in nose cup can be filtered by filter membrane, including
The gas of the gas sucked and exhalation is carried out filtration of evolving, it is to avoid exhaled gas is piled up dirt degree and is slowly increased, and affects incoming call
The oxygen content of gas；In use for some time, filter membrane is replaceable, thus extends the service life of nose cup.
A kind of sleep nose cup of the present invention, described filter membrane is by 22 parts of polyallyl acrylamide sodium of mass parts, 8 parts of activity
Charcoal, 3 parts of ethyl hydroxybenzoates and 23 parts of anhydrous calcium chloride compositions, the particle diameter of described anhydrous calcium chloride is less than 500 mesh, described polyallyl
The molecular formula of acrylamide sodium is
A kind of sleep nose cup of the present invention, described mid-stent is provided with connection through hole, and described connection through hole runs through support
Upper and lower surface.
Owing to have employed technique scheme, connect through hole and can facilitate the dismounting of appendix, convenient to support, rhinarium
It is timed cleaning with breather, thus ensures safety in utilization.
A kind of sleep nose cup of the present invention, described connection through hole is connected with appendix, and described appendix is located on support
Face side, described appendix front end, through connecting through hole, is connected with pad.
Owing to have employed technique scheme, pad can not only assist fixing breather, simultaneously can consolidating for support
Guarantee is provided surely, increases the frictional force of support and face, thus reduce the probability of support landing.
A kind of sleep nose cup of the present invention, described appendix upper surface is provided with gas sensor, described gas sensor
Connecting with appendix inside, gas circulation status in described gas sensor detection appendix, when gas sensor is in 10s
Detect that gas flows, then send warning.
Owing to have employed technique scheme, by detected gas circulation status, thus patient, asphyxia feelings occur
Lighter warning will be sent under condition, stimulate the nervus centralis of patient, auxiliary to arouse patient muscle and be at tensioned state, from
And assist and avoid the occurrence of long-time asphyxia.
A kind of sleep nose cup of the present invention, described appendix front end is evenly equipped with pore, and described pore is distributed ringwise, institute
State pore to connect with internal stent.
Owing to have employed technique scheme, pore ensure that stablizing of airflow between appendix and breather
Property, it is to avoid during eupnea, owing to respiration force causes the rapid instability of air-flow.
A kind of sleep nose cup of the present invention, described pad is fabricated from a flexible material, and described pad includes inhaling from top to bottom
