Abstract

The utility model relates to the field of medical apparatuses, and discloses an artificial nose which comprises a first air-vent and a second air-vent, wherein a cavity is located between the first air-vent and the second air-vent, and is characterized in that the cavity is provided with a filtering device with humidification indication. The utility model can directly indicate the use state of the artificial nose, and prompts to change the artificial nose in proper time, thereby not only preventing disadvantage affects to the health of patients as the artificial nose is used overtime, but also preventing waste as the use time limit is insufficient.

Description

A kind of artificial nose

Technical field

This utility model relates to medical instruments field, particularly relates to the artificial nose that a kind of artificial airway of being used for replaces people's nasal cavity function.

Background technology

Artificial nose has another name called temperature-wet exchange filter, heat and moisture condensation device, is a kind of being positioned on tracheostoma or the tracheal intubation with the medical apparatus and instruments warm and gas that moist patient was breathed.Artificial nose is as the passive-type wet heat exchanger, bionical camel nose is manufactured and is formed, profile is a kind of adapter structure, its inside is the defecator of the fine-meshed screen knot structure made by several layers of absorbent material or hydrophilic compounds, have appropriate humidifying, effectively add gentle filtering function, heat in the expired gas and aqueous vapor can be collected and remained, with gas warm and that humidifying sucks.Gas is through artificial nose when air-breathing, and heat and moisture are brought in the air flue, can guarantee that air flue obtains effective, suitable humidifying.Simultaneously, it has certain filtration to pathogen such as antibacterials, can reduce pipeline by the danger of germ contamination.Therefore artificial nose can be passed through to keep stationary temperature and humidity in the respiratory tract, and keeps the normal physiological function of respiratory tract mucus-cilium system, is widely used in setting up artificial airway's patient at present.

The artificial nose volume is small and exquisite, and is very easy to use simple, and is expendable consumed product.Only need during use an end is connected with the artificial airway, the other end is connected with breathing circuit or direct communicating with ambient atmosphere gets final product.

Because different patients' respiratory tract humidity there are differences with temperature, the humidity and the temperature of different breathing circuit and ambient atmosphere are also inequality, thereby at present to effective pot life of artificial nose clear and definite regulation all, user more can't be determined.The artificial nose that surpasses the pot life, not only the filtering and wetting function reduces or forfeiture, airway resistance is obviously risen, thereby patient's respiratory function is had a negative impact.And change before the limit in use, certainly will cause unnecessary waste again.Existing artificial nose in use is difficult to judge when change.

The utility model content

The purpose of this utility model is at the deficiencies in the prior art, the artificial nose that provides a kind of in use easy judgement when to change.

The technical solution of the utility model is as follows:

A kind of artificial nose comprises first blow vent and second blow vent, is a cavity between first blow vent and second blow vent, it is characterized in that: the defecator that is provided with the indication of band humidifying in the cavity.

Influence filtering function and heat insulation function after the defecator humidifying in the artificial nose, and increase aeration resistance, therefore, the humidifying degree of defecator can be used as effectively accusing of of artificial nose pot life, defecator of the present utility model possesses the humidifying deictic function, the behaviour in service that can intuitively reflect artificial nose, thus prompting is in time changed.

This utility model can indicate the user mode of artificial nose intuitively, thus prompting in time changed, both can avoid artificial nose to use over time limit and caused adverse effect to patient health, the waste that can avoid the pot life deficiency to cause again.This utility model has been obtained good benefit when increasing few cost.

The specific embodiment

The utility model is further described below in conjunction with drawings and Examples.

Embodiment 1

As shown in Figure 2, artificial nose comprises that between first blow vent 1 and second blow vent, 2, the first blow vents 1 and second blow vent 2 be a circular cylindrical cavity, is provided with defecator 3 in the cavity, and the lateral wall of defecator 3 is provided with humidifying bar 4.The pore grenadine that defecator 3 is made by absorbent material and hydrophilic compounds for one deck, humidifying bar 4 can be humidifying indication reagent paper, perhaps directly the humidifying indicator are coated on the defecator 3 to form.

Artificial nose in use, humidifying bar 4 variable color gradually along with the continuous humidifying of defecator 3 when the whole variable color of humidifying bar 4, means defecator 3 complete humidifyings, promptly artificial nose should in time be changed to the pot life.

Embodiment 2

As different from Example 1, present embodiment replaces humidifying bar 4 with humidifying indication point 5.On function, several humidifying indication points 5 are formed one group and are equivalent to a humidifying bar 4.Humidifying indication point 5 can be humidifying indication reagent paper, perhaps directly the humidifying indicator is put on defecator 3 to form.

Embodiment 3

As different from Example 1, present embodiment perhaps wraps the lateral wall coating humidifying indicator of whole defecator 3 with the lateral wall of a bulk of humidifying indication reagent paper with defecator 3.

Embodiment 4

Defecator 3 differences as different from Example 1.

The defecator 3 of present embodiment comprises two filter layers, and wherein first filter course is the pore grenadine, perpendicular to the airflow direction of artificial nose; Second filter course is coiled to form by the fine-meshed screen sliver.The fine-meshed screen sliver preferably adopts gauffer shape fine-meshed screen sliver.

Embodiment 5

Defecator 3 differences as different from Example 1.

The defecator 3 of present embodiment comprises two filter layers, and wherein first filter course is the pore grenadine, perpendicular to the airflow direction of artificial nose; Second filter course is coiled to form after stacked by gauffer shape fine-meshed screen sliver and plate shaped fine-meshed screen sliver again.

The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
