Abstract
A nasal oxygen cannula comprises a cannula body. The cannula body is provided with a nasal tube communicated with the cannula body, and a non-return valve which can ensure that the oxygen can flow towards the nasal tube only from the cannula body is arranged in the position where the cannula body is communicated with the nasal tube. Because the non-return valve is arranged, and the non-return valve is open during the inspiration, the oxygen can enter the nasal cavity smoothly. The non-return valve is closed automatically during the expiration, thereby preventing the waste of the oxygen.
Description
(1) technical field
The present invention relates to a kind of nasal oxygen tube.
(2) background technology
Nasal oxygen tube is a kind of medical apparatus and instruments commonly used, and nasal oxygen tube comprises body, and body has the nose conduit with nasal oxygen tube UNICOM, and the nose conduit is filled in patients breathing in the nostril during use.Its shortcoming that also exists is: no matter be in expiration or when air-breathing, oxygen all can be from the turnover of nose conduit, and does not need oxygen when in fact exhaling, and therefore can cause the waste of oxygen.
(3) summary of the invention
In order to overcome the above-mentioned deficiency of existing nasal oxygen tube, this utility model provides a kind of nasal oxygen tube of conserve oxygen.
The technical scheme in the invention for solving the technical problem is: a kind of nasal oxygen tube, comprise body, and described body has the nose conduit with this body UNICOM, and the connection position of described body and nose conduit is provided with and makes oxygen flow to check valve in the nose conduit from body.
Concrete, described check valve is flexible valve block, and described flexible valve block is positioned at the connection position of described nose conduit and described body, and an end of this flexibility valve block is connected with described body or nose conduit, and the other end is a free end.
Beneficial effect of the present invention is: owing to be provided with check valve, one-way valve opens when air-breathing, oxygen can enter into nasal cavity swimmingly.Check valve is closed automatically during expiration, thereby stops the waste of oxygen.
(4) description of drawings
Fig. 1 is the structural representation of the nasal oxygen tube of embodiment one.
Fig. 2 is the structural representation of the nasal oxygen tube of embodiment two.
(5) specific embodiment
Below in conjunction with the drawings and specific embodiments the present invention is described in further detail.
Embodiment one
With reference to Fig. 1, a kind of nasal oxygen tube, comprise body 1, described body 1 has a nose conduit 2 with described body UNICOM, and the connection position of described body 1 and nose conduit 2 is provided with and makes oxygen flow to check valve in the nose conduit from body, in the present embodiment, described check valve is flexible valve block 3, described flexible valve block 3 is positioned at the connection position of described nose conduit 2 and described body 1, and an end of this flexibility valve block 3 is connected with described nose conduit 2, and the other end is a free end.
Owing to be provided with check valve, the free end of flexible valve block 3 (shown in the dotted line) is opened when air-breathing, and oxygen can enter into nasal cavity swimmingly.Have flexible valve block 3 (shown in the solid line) during expiration and under the effect of the gas of its elasticity and exhalation, UNICOM's mouth of body and nose conduit is closed, thus the waste of prevention oxygen.
Certainly the form of check valve is not limited thereto, and can also be other forms of check valve.
Embodiment two
With reference to Fig. 2, a kind of nasal oxygen tube, comprise body 1, described body 1 has two nose conduits 2 with described body UNICOM, and the connection position of described body 1 and nose conduit 2 is provided with and makes oxygen flow to check valve in the nose conduit from body, in the present embodiment, described check valve is flexible valve block 3, described flexible valve block 3 is positioned at the connection position of described nose conduit 2 and described body 1, and an end of this flexibility valve block 3 is connected with described nose conduit 2, and the other end is a free end.
Owing to be provided with check valve, the free end of flexible valve block 3 (shown in the dotted line) is opened when air-breathing, and oxygen can enter into nasal cavity swimmingly.Have flexible valve block 3 (shown in the solid line) during expiration and under the effect of the gas of its elasticity and exhalation, UNICOM's mouth of body and nose conduit is closed, thus the waste of prevention oxygen.
Certainly the form of check valve is not limited thereto, and can also be other forms of check valve.
Claims (2)
1. a nasal oxygen tube comprises body, and described body has the nose conduit with this body UNICOM, it is characterized in that: the connection position of described body and nose conduit is provided with and makes oxygen flow to check valve in the nose conduit from body.
2. nasal oxygen tube as claimed in claim 1, it is characterized in that: described check valve is flexible valve block, described flexible valve block is positioned at the connection position of described nose conduit and described body, and an end of this flexibility valve block is connected with described body or nose conduit, and the other end is a free end.
