Disclosure of Invention
The utility model discloses the technical problem that will solve lies in: provides a novel double-cavity nasal catheter, which solves the problems that the double-cavity nasal catheter is easy to loosen and uncomfortable to wear when adopting a circular fixing method.
The utility model discloses the technical problem that will solve takes following technical scheme to realize:
the utility model provides a novel two-chamber nasal catheter, includes the oxygen hose, the one end of oxygen hose is cyclic annular setting, it detains to slide to cup joint the activity on the oxygen hose, fixed intercommunication has the nasal cavity pipe on the cyclic annular oxygen hose, fixed intercommunication has two pipes on the nasal cavity pipe, still is provided with the collection structure, it has cup jointed the sliding sleeve still to slide on the cyclic annular oxygen hose, fixedly connected with fixed band on the sliding sleeve.
As a preferable example, the collection structure includes a sealing plug and a soft membrane, the nasal cavity tube is provided with a port, the sealing plug is arranged in the port, and the soft membrane covers the connection part of the oxygen tube and the nasal cavity tube.
As a preferred example, the poking direction of the soft membrane is the air inlet direction of the oxygen pipe.
As a preferable example, one end of the fixing band, which is far away from the sliding sleeve, is provided with a magic tape.
As a preferable example, the nasal cavity tube is also provided with a nose support with a round contact surface.
The utility model has the advantages that: the utility model discloses aim at two nasal nostrils with the pipe, encircle to the top of the head behind the both sides ear, the activity is detained and is detained before the forehead or the top of the head, adjusts the position of fixed band on the oxygen hose, with this fixed band around can firmly fix the oxygen hose around the round behind the pillow to it is comfortable to wear, the oxygen hose before lieing in the ear can not extruded with the position of lying on the side simultaneously.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the structure of the present invention;
fig. 3 is a schematic view of the structure of the acquisition structure.
In the figure: the nasal cavity catheter comprises a movable buckle 1, an oxygen tube 2, a sliding sleeve 3, a fixing band 4, a catheter 5, a nasal cavity tube 6, a nose support 7, a sealing plug 8, a magic tape 9 and a soft membrane 10.
Detailed Description
In order to make the technical means, the creation features, the achievement purposes and the functions of the present invention easy to understand and understand, the present invention is further explained by combining the following specific drawings.
As shown in fig. 1-3, a novel double-chamber nasal catheter comprises an oxygen tube 2, wherein one end of the oxygen tube 2 is annularly arranged, a movable buckle 1 is sleeved on the oxygen tube 2 in a sliding manner, a nasal cavity tube 6 is fixedly communicated with the annular oxygen tube 2, two catheters 5 are fixedly communicated with the nasal cavity tube 6, an acquisition structure is further arranged, a sliding sleeve 3 is further sleeved on the annular oxygen tube 2 in a sliding manner, and a fixing band 4 is fixedly connected to the sliding sleeve 3.
The collecting structure comprises a sealing plug 8 and a soft membrane 10, a connector is arranged on the nasal tube 6, the sealing plug 8 is arranged in the connector, and the soft membrane 10 covers the connecting part of the oxygen tube 2 and the nasal tube 6.
Adopt above-mentioned scheme, current two-chamber nasal catheter only has the effect of oxygen uptake, can not compromise expired gas's collection function, if to carbon dioxide gas's collection, need use the pipe in addition to gather the work, it is more troublesome to use, can conveniently collect expired gas through set up the collection structure on nasal cavity pipe 6.
The poking direction of the soft membrane 10 is the air inlet direction of the oxygen tube 2, the soft membrane 10 can be easily poked when the oxygen tube 2 passes through, the oxygen inhalation cannot be blocked due to the soft and light-thin properties of the soft membrane 10, and when the airflow is reversed, the soft membrane 10 is blown by the airflow to be in contact with the inner wall of the nasal cavity tube 6, so that a connecting port of the nasal cavity tube 6 and the oxygen tube 2 is sealed.
One end of the fixing band 4 far away from the sliding sleeve 3 is provided with a magic tape 9, a hair surface is arranged on the fixing band 4, and the fixing band 4 is conveniently fixed and detached by the magic tape 4.
The nasal cavity tube 6 is also provided with a nose support 7 with a round contact surface, so that the problem of redness and injury caused by skin compression is greatly reduced.
The working principle is as follows: when in use, the catheter 5 is aligned with the double nasal nares and encircles to the top of the head through the ears at the two sides, the movable buckle 1 is buckled on the forehead or the top of the head, the position of the sliding sleeve 3 is adjusted on the oxygen tube 2, the fixing band 4 is wound around the back of the pillow for one circle, and is adhered on the fixing band 4 by using a magic tape 9, the oxygen tube 2 can be firmly fixed and is comfortable to wear, meanwhile, the oxygen tube 2 in front of the ear can not be extruded in the horizontal position and the lateral position, when the carbon dioxide gas is required to be collected, the sealing plug 8 is pulled out, the carbon dioxide collecting pipe is inserted into the interface, at this time, the oxygen supply is temporarily stopped, and since the soft membrane 10 can move only in the direction in which the oxygen flows toward the nasal cavity, so that carbon dioxide exhaled by the user's nares now enters the nasal cavity tube 6, the flexible membrane 10 seals off the oxygen tube 2 so that carbon dioxide is collected via the mouthpiece and the carbon dioxide collection tube.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and such changes and modifications fall within the scope of the claimed invention. The scope of the invention is defined by the appended claims and equivalents thereof.
