The connection mode of tube body and the second tube body is different.In the present embodiment, the first tube body and the second tube body form concealed connection.
Fig. 4 is the structure diagram according to another stomach tube for being preferably implemented and exemplifying.As shown in figure 4, stomach tube includes bottom
Closing and base wall are equipped with the first tube body 1, the first tube body positioning seat 2 and the second tube body 3 of multiple circular holes.
Second tube body 3 is placed on 1 inside of the first tube body and 3 connecting pin end of the second tube body connects with 1 inner wall sealing of the first tube body
It connects.The periphery of second tube body, 3 connecting pin is equipped with elastic component 5, and elastic component 5 is abutted with the inner wall of the first tube body 1；First tube body 1
At least one through hole 6 is provided on the wall at top, the aperture of through hole is more than the outer diameter of the elastic component.Second tube body 3 is in the first pipe
It is moved in body 1, and when being moved to the first 1 top of tube body, the through hole 6 of elastic component 5 into setting at the top of the first tube body is interior and will
Second tube body 3 is fixed.
First tube body positioning seat 2 includes pedestal 21 and the locating piece being arranged on pedestal 21.The both sides of pedestal 21 connect respectively
Elastic webbing 23 is connected to, the other end of every elastic webbing 23 sets ear muff 24.Locating piece include upper clip and lower clip, upper clip with
Lower clip is opposed to form a hole shape holding section, and the first tube body positioning seat 2 is selectively fixed on the first pipe by hole shape holding section
Any position of 1 middle and upper part of body.
As the one of which preferred embodiment in each embodiment, the lower clip of locating piece is equipped with card convex, and upper clip is
Flexible-belt, upper clip are equipped with by multiple mounting holes arranged in a straight line, and different mounting holes, which are fixed in card convex, can be achieved holding section
The adjusting in aperture.
As another preferred embodiment in each embodiment, an end of the lower clip of locating piece can set U-shaped card
Circle, the shaft for connecting retainer ring both ends, the clamp spring being arranged in shaft and the shifting block for being arranged at shaft wherein one end.Shifting block band
When turn axis rotates, clamp spring is rotated with shaft.Upper clip is flexible-belt, that face opposite with lower clip is equipped with by more in upper clip
The raised band that a protrusion linearly rearranges, when upper clip penetrates U-shaped card circle and protrusion band is located at clamp spring top, clamp spring insertion
Upper clip is fixed in groove between two adjacent protrusions.In shifting block rotating shaft, clamp spring turns to raised band with shaft
In the groove of different position, to realize the adjusting in holding section aperture.
It should be noted that the structure of locating piece is only exemplary in the application, it is every first tube body to be carried out
It fixes and can realize that the structure of holding section aperture adjustment each falls within protection scope of the present invention.
The application method of the stomach tube in the embodiment is specifically addressed below.
The length range of the first tube body is used for the supply of food and nutrition generally at 0.7~1 meter in the present embodiment.
Stomach tube is for when subsisting with nutrition, the second tube body 3 to be hidden in the first tubular body.When the stomach of the first tube body insertion patient
And after length adjustment is appropriate, the first tube body positioning seat 2 is adjusted in the first pipe by adjusting the aperture of locating piece pass holding section
The position of body middle and upper part until after the first tube body positioning seat 2 is fixed on the position below patient nostril, locks locating piece pass
The aperture of holding section is so that the first tube body positioning seat 2 is fixed on the first tube body.By two ear muffs on the first tube body positioning seat 2
24 are respectively sleeved on the ears of patient, so as to which the first tube body be fixed.
When needing to carry out gastric juice suction to patient, by the second tube body by being extracted out in the first tube body, when the second tube body connects
After the elastic component at end is embedded in the through hole set at the top of the first tube body, the second tube body is fixed, and the length of stomach tube extends to 1.5 meters at this time
Left and right.That end opposite with connecting pin can be connected by the second connector with pumping equipment in second tube body.Wherein, the second connection
The connector identical with the first connecting-piece structure can be selected in part.When suction operation need not be carried out, promote on the second tube body
The direction of elastic component to the first body central axis is mobile and presses the second tube body, and the second tube body is contracted to the first tube body at this time
It is interior.
From above technical scheme, tube body is split as be detachably connected two sections of pipes by the stomach tube in above-described embodiment
Body, when in use, length will not form winding to the first tube body, and the first tube body is fixed by ear muff, and adhesive tape sticking is avoided to make
Into the itch of patient skin.Meanwhile the exchange use of two sections of tube bodies can meet offer food and gastric juice aspirates two kinds of functions, therefore
It is that cocoa takes into account offer food and gastric juice suction that stomach tube in the present embodiment, which has, can also avoid part pipeline that from must winding and glue
The advantages of being affixed on patient face.
Further, in order to ensure the health of the second tube body and the first tube body lower part food, with being connected in the second tube body
That opposite end is held to be equipped with for blocking the 3rd sealing-plug 8 of the second tube body.
In general, the bore of the interface for the second tube body being connected with pumping equipment is larger.In general, injection food or the note of nutrition
The injection port diameter of emitter is often below the bore at the top of flexible rubber hose, in order to ensure injecting the health of food, avoids other impurities
Through the gap between the second tube body and injection port into the first tube body, further, the stomach tube in the present embodiment is close the 3rd
Second injection orifice identical with syringe injection port diameter is provided on blocking, the 3rd sealing-plug is equipped with to block the second injection
The 4th sealing-plug (not shown) in hole.
It should be noted that the first tube body is only exemplary with the concealed structure that the second tube body is formed in the application,
It is every that the first tube body and the second tube body can be made to be in the structure of the first length such as 0.7-1 meters and the second length such as 1.5 meters
Each fall within protection scope of the present invention.
From above technical scheme, the stomach tube in the present invention can be at only using the first tube body and using the first tube body and
Second two kinds of tube body use state.When only using the first tube body, the length of stomach tube will not form winding, and the first tube body passes through ear
Set is fixed, and adhesive tape sticking is avoided to cause patient facial region's skin injury, allergy itch.It, can during using the first tube body and the second tube body
It is connected with pumping equipment and carries out pumping operation.It follows that the stomach tube in the present invention, which has, can take into account offer enteral nutrition
Liquid, intake drug and other spoon meats and gastric juice suction, the multi-functional of gastrointestinal decompression, can also avoid part pipeline that from must twining
Around and the advantages of be pasted on patient facial region, reduce the risk of unexpectedly drawn tubes.
It should be appreciated that the invention is not limited in the precision architecture for being described above and being shown in the drawings, and
And various modifications and changes may be made without departing from the scope thereof.The scope of the present invention is only limited by appended claim.
