Description
Technical field
This utility model belongs to the technical field of medical apparatus and instruments, in particular to a kind of nasal cavity dilator.
Background technology
The cause of disease causing breathing to have some setbacks by nasal obstruction is a lot, but mostly reason is that in intranarial nasal polyp enlargement or nose, diaphragm bends, cause intranarial upper airway stricture, total blockage even, air mass flow is reduced, cause the situation of snoring and pulmonary's anoxia to occur, affect greatly to the body and mind of patient and healthy generation.
Existing nasal dilator, device is too simple, and without the moulding function of the wing of nose, easily deviates from during use, and turnover is slided, damage nasal cavity and nasal meatus, is unfavorable for that nose is healthy.
Summary of the invention
In order to overcome the deficiencies in the prior art, this utility model provide a kind of rational in infrastructure, easy and simple to handle, to have nasal vestibule moulding, improves the nasal cavity dilator of Nasal airway simultaneously.
The technical solution of the utility model: a kind of nasal cavity dilator, the outer tube comprise the interior pipe of inner hollow, coaxially arranging with described interior pipe, is fixed on the expansion capsule on outer tube and expands the administration chamber of capsule periphery; Described expansion capsule is having edge in snowflake sheet shape with outer axial tube on vertical cross section, and described edge is round and smooth and on same circumference, after expansion capsule is full, form multiple passage; The outer wall in described administration chamber is can by the semipermeable membrane of compression swelling; Closed at both ends between described outer tube and interior pipe forms blind end, described blind end is provided with self-closing gas injection port, is radially formed with filling channel between described outer tube and interior pipe, and the tube wall of described outer tube is evenly provided with air-vent; The end in described administration chamber is provided with self-closing liquid injection port.
Further, preferably, the outer surface of described semipermeable membrane is irregular is distributed with salient point, and described salient point is biological coating or medication coat.
Further, preferably, described edge is 3 to 5 lobes.
Further, preferably, the inwall of described interior pipe is connected with drainage screen.
Compared with prior art, the advantage of nasal cavity dilator of the present utility model is:
This utility model structure is simple, reasonable in design, general general sacculus dredging the planning function can not only be had, more because expansion capsule edge is 3 to 5 lobes, after expansion capsule is full, forms multiple passage, make the expansion capsule after expansion can not block nasal cavity completely, make the air-flow in nasal cavity still be in maintenance circulation status, anti-extrusion performance improves.
By the administration chamber that expansion capsule periphery is arranged, the outer wall in administration chamber is by the semipermeable membrane of compression swelling, to administration intracavity input water or therapeutic medicament, can stop pressure ulcer, reduce to stimulate, effectively alleviate the wound of nasal mucosa.
The outer surface of edge protuberance is irregular is distributed with several for biological or medication coat salient point, increases friction, can be degradable, reduces inflammation, plays good slow releasing function.
Drainage screen on the inwall of interior pipe, noxious bacteria and the allergin that also can completely cut off external very big part enter in body, can be the air that user provides more clean.

Detailed description of the invention
Referring to accompanying drawing, provide detailed description of the invention of the present utility model, be used for being further described formation of the present utility model.
As a kind of nasal cavity dilator in Fig. 1,2,3, comprise the interior pipe 10 of inner hollow, with interior pipe 10 coaxial arrange outer tube 20, be fixed on the expansion capsule 30 on outer tube 20 and expand the administration chamber 40 of capsule 30 periphery; Expansion capsule 30 has the edge 31 in snowflake sheet shape on the cross section axially vertical with outer tube 20, and edge 31 is round and smooth and on same circumference, after expansion capsule 30 is full, form multiple passage 32; The outer wall in administration chamber 40 is can by the semipermeable membrane 41 of compression swelling; Closed at both ends between outer tube 20 and interior pipe 10 forms blind end 50, blind end 50 is provided with self-closing gas injection port 51, is radially formed with filling channel 52 between outer tube 20 and interior pipe 10, and the tube wall of outer tube 20 is evenly provided with air-vent 21; The end in administration chamber 40 is provided with self-closing liquid injection port 42.
Further, preferably, the outer surface of semipermeable membrane 41 is irregular is distributed with salient point 43, and salient point 43 is biological coating or medication coat.
Further, preferably, edge 31 is 3 to 5 lobes.
Further, preferably, the inwall of interior pipe 10 is connected with drainage screen 60.
During use, nasal cavity dilator is inserted nasal vestibule, by self-closing gas injection port 51 to injecting gas in expansion capsule 30, in administration chamber 40, medicament or water is injected by self-closing liquid injection port 42, make the wing of nose keep extending out the state of stretching, extension, be beneficial to and improve nasal vestibule deformity, improve BITONG airway dysfunction simultaneously.
Compared with prior art, the advantage of nasal cavity dilator of the present utility model is:
This utility model structure is simple, reasonable in design, general general sacculus dredging the planning function can not only be had, more because expansion capsule edge is 3 to 5 lobes, after expansion capsule is full, forms multiple passage, make the expansion capsule after expansion can not block nasal cavity completely, make the air-flow in nasal cavity still be in maintenance circulation status, anti-extrusion performance improves.
By the administration chamber that expansion capsule periphery is arranged, the outer wall in administration chamber is by the semipermeable membrane of compression swelling, to administration intracavity input water or therapeutic medicament, can stop pressure ulcer, reduce to stimulate, effectively alleviate the wound of nasal mucosa.
The outer surface of edge protuberance is irregular is distributed with several for biological or medication coat salient point, increases friction, can be degradable, reduces inflammation, plays good slow releasing function.
Drainage screen on the inwall of interior pipe, noxious bacteria and the allergin that also can completely cut off external very big part enter in body, can be the air that user provides more clean.
Embodiment is only be described the preferred embodiment of the present invention above, not limits the spirit and scope of the present invention.Under the prerequisite not departing from design concept of the present invention; the various modification that this area ordinary person makes technical scheme of the present invention and improvement; all should drop into protection scope of the present invention, the technology contents of request protection of the present invention, all records in detail in the claims.
