Abstract

The utility model relates to an artificial nose, which is composed of an air hole, an inner filtering tube, an outer cannula, a sealing ring and an air connection opening. One end of the outer cannula adopts a whole-opening form, and the other end adopts a closed form. A circular air hole is arranged at the closed end of the outer cannula. The inner filtering tube which is penetrated from top to bottom is arranged in the center of the outer cannula, the inner filtering tube is a circular pipe on the body of which a breathing hole is arranged, the air connection opening is arranged at the tail end of the inner filtering tube, and the sealing ring which can not generate the air leakage phenomenon from the outer cannula and the inner filtering tube is arranged in the intercalated layer at the tail end of the filtering tube and the outer cannula. The medical gauze used for filtering is arranged between both the intercalated layers of the outer cannula and the inner filtering tube in the sealing ring. When being used, the moistening treatment is required to be performed to the medical gauze used for filtering. When the artificial nose of the utility model is used, the air absorbed is filtered through the moistened cotton yarn, the bacteria dust with big granule can be blocked, and the humidity of the absorbed air can be increased. The manufacturing process of the artificial nose is simple, the use is convenient, and during the using process, the humiture is feasible.

Description

Artificial nose

Technical field:

This utility model relates to the medical and health use device, relates in particular to artificial nose.

Background technology:

The patient of tracheal intubation, tracheotomy, since upper respiratory tract to suck the heating of gas, moistening and filter cleaning physiological function disappears, and suck exsiccant gas for a long time alveolar surfactant is damaged, the epithelial ciliary movement of bronchial mucosa weakens or disappears, can make that secretions is sticky, form a scab, sputum is difficult to discharge, and can increase the chance of pulmonary infection and the difficulty of air flue nursing.

The utility model content:

The purpose of this utility model is, overcomes the deficiencies in the prior art part, and a kind of artificial nose is provided, and is easy to use, and filterable air does not contain particulate matter, and relative temperature is near human body temperature, and can manual adjustment keep enough humidity.

Artificial nose described in the utility model, include pore, interior chimney filter, trocar sheath, sealing ring and connect QI KOU and form, said trocar sheath is a main component of the present utility model, is cylinder empty in a section on the whole, one end is a standard-sized sheet degree of lip-rounding formula, and the other end is a closing form.Telescopic outside blind end is provided with circular pore.Telescopic outside center, be provided with the interior chimney filter of up/down perforation, chimney filter is the pipe that a pipe shaft is provided with passage in said, be provided with at the end of interior chimney filter and connect QI KOU, in the interlayer of interior chimney filter end and trocar sheath end, being provided with can not be from the sealing ring that leaks gas between trocar sheath and the interior chimney filter.Between the trocar sheath in sealing ring and the interlayer of interior chimney filter, be provided with to filter and use hospital gauze.

Use artificial nose described in the utility model, the gas of suction filters through moistening cotton yarn, can stop bulky grain bacterium dirt, and has increased the humidity that sucks air; Moisture of taking out of during breath and temperature can partly be retained in the artificial nose, the gas of incoming call are had the effect of heating, humidification.In the use, artificial nose is connected with the artificial airway closely, and the patient stands up, difficult drop-off when coughing, and reduced the difficulty to the pollution and the nursing of environment.Employed gauze pollutes the replaceable cleaning in back, and the sterilization back is reusable, has alleviated patient's burden.This utility model processing technology is simple, and is easy to use, and the humiture in the use is suitable.

Description of drawings:

Accompanying drawing is the structural representation of artificial nose described in the utility model.The outer chimney filter 4-sealing ring 5-of chimney filter 3-connects QI KOU in the 1-pore 2-

The specific embodiment:

Referring now to accompanying drawing 1, be described as follows in conjunction with the embodiments: artificial nose described in the utility model, include pore 1, interior chimney filter 2, trocar sheath 3, sealing ring 4 and connect QI KOU 5 and form, said trocar sheath 3 is main components of the present utility model, be cylinder empty in a section on the whole, one end is a standard-sized sheet degree of lip-rounding formula, and the other end is a closing form.At the blind end of trocar sheath 3, be provided with circular pore 1.Center at trocar sheath 3, be provided with the interior chimney filter 2 of up/down perforation, chimney filter 2 is pipes that a pipe shaft is provided with passage in said, be provided with at the end of interior chimney filter 2 and connect QI KOU 5, in the interlayer of interior chimney filter 2 ends and trocar sheath 3 ends, being provided with can not be from the sealing ring 4 of gas leakage between trocar sheath 3 and the interior chimney filter 2.Between the trocar sheath 3 in sealing ring 4 and the interlayer of interior chimney filter 2, be provided with to filter and use hospital gauze.Need do to add wet process to filtering during use with hospital gauze.Use artificial nose described in the utility model, the gas of suction filters through moistening cotton yarn, can stop bulky grain bacterium dirt, and has increased the humidity that sucks air; Moisture of taking out of during breath and temperature can partly be retained in the artificial nose, the gas of incoming call are had the effect of heating, humidification.In the use, artificial nose is connected with the artificial airway closely, and the patient stands up, difficult drop-off when coughing, and reduced the difficulty to the pollution and the nursing of environment.Employed gauze pollutes the replaceable cleaning in back, and the sterilization back is reusable, has alleviated patient's burden.This utility model processing technology is simple, and is easy to use, and the humiture in the use is suitable.
