Description
[technical field]
The utility model relates to technical field of medical instrument, in particular to a kind of modified artificial nose.
[background technique]
In intensive care unit, critical patient is often to implement trachea cannula or bronchotomu convenient for airway management,
To keep airway patency, alleviate airway obstruction, it is ensured that pulmonary ventilation function normally plays.When normal, nose, throat, respiratory tract pair
The gas of sucking has heating and humidifying effect, but after establishing artificial airway, can only absorb moisture from respiratory tract itself and cause
Respiratory mucosa is dry.
The common air flue humidification method of Hospitals at Present is using artificial nose, referred to as disposable wet heat exchanger (HME), packet
Include the gentle pipe adapter tube of artificial nose filter, wherein artificial nose filter housing is sealing, and inside is by water-absorbent material and parent
Hydrate constitute, it have efficient humidifying, heating and filtration, and tracheal cannula for connect human airway notch and
Artificial nose filter.
But in terms of usually there is following two when in use in the artificial nose of existing market: (1) patient's expectoration
Sputum directly enters artificial nose filter from tracheal cannula, causes to receive pollution inside artificial nose, and replacement frequently, increases medical care people
The workload of member and the medical expense of patient；(2) tracheal cannula is single channel, air inlet and a shared pipeline of exhaling, and is easy
Growth bacterium, cross-infection, therapeutic effect are poor.
Although in existing patented technology, also there is the research much improved to artificial nose, there is different ask
Topic.For example, although a kind of of Patent No. CN204395163U discloses with the artificial nose for holding phlegm chamber in air pipe connector
On set it is dismountable hold phlegm chamber, but air inlet and outlet still share a pipeline, are easy infection；Patent No.
One kind of CN204582198U, which can collect phlegm formula artificial nose and although also disclose, is arranged sputum collection bag on tracheal tube connector,
But the sputum collection bag is located at the top of the tracheal tube connector vertically, and entrance is equipped with one-way valve, on the one hand
Human body autogenous cutting mouth can be made to be oppressed, the sputum of another aspect patient's expectoration is likely to can not to wash open one-way valve and enters sputum receipts
Collect bag, can get lodged in tracheal tube instead；And although the artificial nose of Patent No. 100493644C discloses going out for corrugated hose
Gas, air inlet are respectively equipped with unidirectional outlet clack valve, one-way air inlet clack valve, but sputum a part of patient's expectoration can be with unidirectional
Outlet valve spray, unhygienic, a part can be accumulated in the corrugated hose, block corrugated hose, influence patient respiratory and
It is easy to cause infection.
[utility model content]
For overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of modified artificial nose, this changes
