Abstract
The invention provides a double-cavity nasal gastric tube which comprises a tube body and an interlayer, wherein the interlayer is extended along with the length direction of the tube body to divide the tube body into double cavities, one cavity is a wire guide cavity, the other cavity is an infusion tube cavity, one end of the wire guide cavity is opened, the other end of the wire guide cavity is a blind end, the blind end is internally provided with a section of support body, an infusion cavity is provided with a plurality of side holes at the blind end, and the length of the support body is matched with the distributing lengths of the side holes. When the double-cavity nasal gastric tube is in use after entering into the human body, the double-cavity nasal gastric tube can not be folded since each side hole is provided with a section of the support body, so that the smoothness of a catheter can be effectively guaranteed.
Description
Technical field
The present invention relates to technical field of medical, particularly relate to a kind of two-chamber Nasal gastrointestinal tube.
Background technology
Traditional Nasal gastrointestinal tube body design is generally single chamber; Guiding wire is positioned at tube chamber; Because the guiding wire diameter is much littler than lumen diameter, make seal wire not be in perfect condition to the support of Nasal gastrointestinal tube, insert in the process of human body at Nasal gastrointestinal tube; Seal wire twists easily, is unfavorable for that body gets into human body smoothly; The Nasal gastrointestinal tube that has occurred a kind of two-chamber in recent years; A kind of nasogastric tube that has double lumen is disclosed in the patent of invention like Chinese patent 200910037178.2; Include transfusion lumen; In body, also be provided with the guidewire lumen that supplies guiding wire to insert, this guidewire lumen end is a cecum, and the diameter of described guidewire lumen is suitable with the guiding wire diameter.The advantage of this nasogastric tube is: 1. efficiently solve the problem that guiding wire directly contacts with juice, reduce the probability that infects; 2. make the diameter of guidewire lumen quite, can increase the intensity of nasogastric tube body greatly, make more smooth and easy and accurate positioning when inserting in the patient body, once insert, avoid repetitive operation, reduce patient's misery with regard to complete operation with the guiding wire diameter.But because the seal wire of this body does not extend into the end of body fully; In the process of inserting human body; When perhaps being detained human body, the phenomenon that gives a discount will appear in one section body that its front end has side opening, causes intubate smoothly; The serious circulation that may influence side opening, or block body.
Summary of the invention
To the objective of the invention is in order addressing the above problem, a kind of two-chamber Nasal gastrointestinal tube to be provided.
Technical scheme of the present invention is: a kind of two-chamber Nasal gastrointestinal tube, comprise body and interlayer, and this interlayer separates into two-chamber along the extension of body length direction with body; One is guidewire lumen in two chambeies, and another is a transfusion lumen, and an end of guidewire lumen is uncovered; The other end is a cecum; In cecum, be provided with one section supporter, transfusing chamber has several side openings at the cecum place, the length coupling that the length of supporter and side opening distribute.
Described body is cylindric body, and described guidewire lumen is cylindric body, the cylindric body inscribe of guidewire lumen and the cylindric body of body.
The shape of cross section of described interlayer is a circular arc.
The diameter of described guidewire lumen and the diameter of described supporter coupling.
One end of described supporter contacts the cecum of guidewire lumen, and the other end is fixed through the fixed block that is embedded in the guidewire lumen.
Beneficial effect of the present invention
1, the guidewire lumen that design one independently in the Nasal gastrointestinal tube body, lumen diameter is suitable with the seal wire diameter makes seal wire closely contact with tube chamber, when inserting, effectively strengthens the intensity of tube chamber, improves the success rate of an intubate, alleviates patient's misery; The back seal wire that puts in place is extracted, and conduit is soft, and reducing stimulates nasal mucosa.
2, after Nasal gastrointestinal tube gets into human body, in the process of using,, can not give a discount, can effectively guarantee the unobstructed of conduit because the side opening position is provided with one section supporter.

Fig. 2 is the A-A cross section structure sketch map of Fig. 1;
Fig. 3 is the B-B cross section structure sketch map of Fig. 1;
Axle when Fig. 4 uses for this two-chamber Nasal gastrointestinal tube cuts open structural representation.
The specific embodiment
1. bodys among the figure, 2. interlayer, 3. guidewire lumen, 4. transfusing chamber, 5. supporter, 6. fixed block, 7. side opening
Embodiment: referring to Fig. 1-Fig. 3, a kind of two-chamber Nasal gastrointestinal tube comprises body and interlayer; This interlayer separates into two-chamber along the extension of body length direction with body, and one is guidewire lumen in two chambeies, and another is a transfusion lumen; One end of guidewire lumen is uncovered, and the other end is a cecum, in cecum, is provided with one section supporter; Transfusing chamber has several side openings at the cecum place, the length coupling that the length of supporter and side opening distribute.
Described body is cylindric body, and described guidewire lumen is cylindric body, the cylindric body inscribe of guidewire lumen and the cylindric body of body.
The shape of cross section of described interlayer is a circular arc.
The diameter of described guidewire lumen and the diameter of described supporter coupling.
One end of described supporter contacts the cecum of guidewire lumen, and the other end is fixed through the fixed block that is embedded in the guidewire lumen.
During use, as shown in Figure 4, at the afterbody of this two-chamber Nasal gastrointestinal tube guide member is installed; Movable seal wire is penetrated in its guidewire lumen, just can this two-chamber Nasal gastrointestinal tube be penetrated in the human body, after waiting to penetrate; Movable seal wire is extracted out; Because the existence of the supporter of its front end, front end can not give a discount, and can not influence the entering of liquid.
