Abstract
The invention relates to a disposable oxygen delivery nasal tube (plug). The disposable oxygen delivery nasal tube (plug) is communicated by a connecting piece, a delivery tube and a nasal cavity contact piece, and is formed by sleeving an oxygen enrichment membrane cover on the delivery tube; a nasal cavity or an oral and nasal cavity is covered and closed by arranging the oxygen enrichment membrane cover; oxygen which overflows from the nasal cavity is reserved in the oxygen enrichment membrane cover by utilizing a high oxygen retention function of an oxygen enrichment membrane, so that patients can be inhaled again to avoid waste; and carbon dioxide which is exhaled is discharged from the oxygen enrichment membrane cover by utilizing the high diffusivity of the carbon dioxide in the oxygen enrichment membrane to prevent the exhaled carbon dioxide from being inhaled again.
Description
Technical field
The invention belongs to a kind of medical apparatus and instruments, the disposable delivering oxygen nasal tube (plug) that especially when oxygen therapy, uses.
Background technology
Disposable delivering oxygen nasal tube (plug) uses when being via intranasal application input medical oxygen; Present disposable delivering oxygen nasal tube (plug); Mouth and nose chamber locking device is not set; The mouth and nose chamber is not sealed during use, and oxygen is wasted easily when exhaling so cause, and has report oxygen to be wasted and reaches 30%-70%.
Summary of the invention
In order to overcome present disposable use delivering oxygen nasal tube (plug) when the oxygen therapy, mouth and nose chamber locking device is not set, the mouth and nose chamber is not sealed during use, causes the defective that oxygen is wasted easily when exhaling.
The disposable use delivering oxygen of the present invention nasal tube (plug) is to be connected by connector, carrier pipe, nasal cavity contact to connect, and forms at the sheathed oxygen permeable membrane cover of carrier pipe; It is through the oxygen permeable membrane cover being set, coming to cover sealing to nasal cavity or mouth and nose chamber, the high function of being detained of the oxygen that utilizes oxygen permeable membrane to have; Be retained in the oxygen that overflows nasal cavity in the oxygen permeable membrane cover; Supply the patient to suck once more, avoid waste, and utilize the carbon dioxide high diffusibility of oxygen permeable membrane; Make the carbon dioxide of breathing out when exhaling can discharge the oxygen permeable membrane cover, the carbon dioxide of having avoided breathing out is reverted to take drugs.The beneficial effect of the disposable use delivering oxygen of the present invention nasal tube (plug) is, oxygen is wasted in the time of both can avoiding exhaling, and the carbon dioxide that can avoid again breathing out is reverted to take drugs.
Description of drawings
Below in conjunction with accompanying drawing and embodiment, further specify the disposable use delivering oxygen of the present invention nasal tube (plug)
Fig. 1 is the disposable use delivering oxygen of the present invention nasal tube (plug) structural representation
--connector (2)--carrier pipe among Fig. 1 (1)
(3)--nasal cavity contact (4)--oxygen permeable membrane cover
The specific embodiment
Like Fig. 1, the disposable use delivering oxygen of the present invention nasal tube (plug) is to be connected by connector (1), carrier pipe (2), nasal cavity contact (3) to connect, and sheathed at carrier pipe (2), and oxygen permeable membrane cover (4) is formed, and it is characterized in that: be provided with oxygen permeable membrane cover (4).During use, after nasal cavity places nasal cavity contact (3), with oxygen permeable membrane cover (4), cover sealing to nasal cavity or mouth and nose chamber, reuse connector (1) is communicated with oxygen supply, just can carry out oxygen therapy.The high function of being detained of the oxygen that utilizes the oxygen permeable membrane of oxygen permeable membrane cover (4) to have; Be retained in the oxygen that overflows nasal cavity in the oxygen permeable membrane cover (4); Supply the patient to suck once more, avoid waste, and utilize the carbon dioxide high diffusibility of oxygen permeable membrane; Make the carbon dioxide of breathing out when exhaling can discharge oxygen permeable membrane cover (4), the carbon dioxide of having avoided breathing out is reverted to take drugs.
Claims (1)
1. disposable use delivering oxygen nasal tube (plug) is to be connected by connector, carrier pipe, nasal cavity contact to connect, and sheathed at carrier pipe, and the oxygen permeable membrane cover is formed, and it is characterized in that: be provided with the oxygen permeable membrane cover.
