Abstract

The utility model relates to an artificial nose belonging to the technical field of the medical appliance. A dry throat operated is in sleeve joint with a terminal port out of a tracheal cannula, which can reserve moisture and calorie in the exhaled air of patients, so as to make the air stored in a filter membrane and used repeatedly. Cold air can be blocked and dust and dirt can be filtered when the patients inhale. A moistening and a medicining rings are arranged into moisten or medicine to the air inhaled by the patients, so as to reach the purpose of protection or therapy. The utility model is composed of a case made of a porous circle front cover injected by polystyrol and a pedestal, a circular front grate, a filter membrane, a rear grate, a guard cover, and the moistening and the medicining rings arranged inside, and a rubber connector arranged outside. The utility model has performances of simple structure, air permeability, moistening, cold defense, insulation, and filtration which all reach the physiological function of the nasal cavity, with low cost and nonrecurring usage.

Description

Artificial nose

This utility model belongs to medical instruments field, relate to a kind of artificial nose that can replace human body nasal cavity physiological function, can in the throat postoperative be socketed on replace people's nasal cavity on the external port of slotting tracheal casing pipe, can when the patient exhales, keep moisture content in pulmonary's breath and heat its storage is reused, can stop when air-breathing that cold air prevents that dust and association's bacterium dirt from entering in the lung and can humidification or dosing in patient's inhaled air.

At present, the throat postoperative patient is breathed and is no longer passed through nasal cavity, throat the external port of slotting tracheal casing pipe directly be exposed in the air, when the patient breathes by it, moisture content and heat are constantly lost when exhaling in the lung, cause patient's dry cough discomfort, especially when spring, winter, dry and cold season was air-breathing cold dry air directly into lung, cause patient's chest pain, easily airborne dust, association's bacterium dirt are sucked in the lung again and cause postoperative infection.

The purpose of this utility model is: design provides a kind of artificial nose, can be socketed on the external port of tracheal casing pipe in throat postoperative tight fit, makes moisture content and heat in its reservation patient pulmonary breath, is stored in recycling in the filter membrane; Stop cold air when air-breathing, filtering dust and dirt, antibacterial, and can be to sucking the purpose that air wetting, dosing reach health care, treat.

Implementing measure structure of the present utility model is: use polystyrene injection moulding porous garden shape protecgulum and the base shell as artificial nose, preceding comb of installation garden shape, filter membrane, back comb, door, humidification add cyclome in it, compress after the engaging and with the clamping of rubber union joint to constitute.Protecgulum center projections partial design has center through hole, and convexconcave part design on every side has radial through hole, periphery to design the hole, garden again in order to ventilation breath, is injected with the ring muscle of comb usefulness before compressing in the protecgulum, and the design of protecgulum inward flange has bayonet socket to engage with base.The preceding comb, on combing, the back is injected with each one of card post and hole clipping, design has two through holes on the filter membrane, make preceding comb by two through holes, card post on combing in the back and hole clipping are pegged graft mutually and are compressed filter membrane, design and installation has support between back comb and base, humidification, add medicinal door, be set with humidification between door and base and add cyclome, the door trailing edge have square aperture in case humidification or dosing in respiration channel, the aperture that the chassis side design has the water filling injection to use, so that add water or dosing adds cyclome in humidification, before the base, on the deutostoma edge design have bayonet socket respectively with protecgulum and rubber union joint engagement connection.

Make specific description with accompanying drawing below:

Among the figure: artificial nose is added cyclome (14), base (15), rubber union joint (17) and is compressed clamping and constitute by comb (7), filter membrane (10), door (12), humidification of protecgulum (1), preceding comb, back.

Protecgulum (1) center projections partial design has center through hole (2), convexconcave part design on every side has radial through hole (3), the periphery design has circular hole (4) in order to ventilation breath, be injected with the ring muscle (6) that compresses preceding comb (7) usefulness in the protecgulum (1), protecgulum (1) design has bayonet socket (5) to engage with base (15), the preceding comb, be injected with each one of card post (9) and hole clipping (8) on the back comb (7), design has two through holes (11) on the filter membrane, make preceding comb by the two, the card post (9) of back comb (7) is pegged graft mutually with hole clipping (8) and is compressed filter membrane (10), between back comb (7) and base (15) support is installed, humidification, add medicinal door (12), the suit humidification adds cyclome (14) between door (12) and base (15), door (12) deutostoma edge has square aperture, (13) so as humidification or dosing in respiration channel, the aperture (18) that the side design of base (15) has water filling or injection to use is before it, on the deutostoma edge design have bayonet socket (5) and (16) respectively with protecgulum (1) and rubber union joint (17) engagement connection.

The utility model has the advantages that: aeration and aeration resistance meet the requirement of human respiratory tract's physiological, Humidification, the cold insulation of gear, filterability all reaches the physiological function of human body nasal cavity, can pass through aperture in addition (18) dosing adds cyclome in humidification and has therapeutic action, simple in structure, disposable use, with low cost.
