Abstract

The invention discloses a nasogastric tube with a double-tube cavity, which comprises a perfusion tube cavity, and the inside of the tube body is also provided with a guide wire tube cavity which allows a guide wire to insert in, wherein the tail end of the guide wire tube cavity is a blind end, and the diameter of the guide wire tube cavity is equivalent to that of the guide wire. The nasogastric tube has the advantages that: 1, the problem that the guide wire is directly contacted with exudates in vivo is effectively solved so as to reduce the infection probability; and 2, the diameter of the guide wire tube cavity is made to be equivalent to that of the guide wire so as to greatly increase the strength of the nasogastric tube body, and ensure that the nasogastric tube can be inserted into the body of a patient smoothly and positioned accurately, and the operation can be completed by once insertion so as to avoid repeated operation, and reduce the pain of the patient.

Description

A kind of nasogastric tube that has double lumen

Technical field:

The present invention refers in particular to a kind of nasogastric tube.

Background technology:

Only design in traditional nasogastric tube body a transfusion lumen is arranged, before inserting in the patient body, need inject guiding wire in the transfusion lumen earlier, inject in the process of transfusion lumen at guiding wire, must inject normal saline frequently and be lubricated, sterilize, in injecting the patient body after, because guiding wire places in the transfusion lumen, it directly contacts with the juice of intracorporeal organ, if sterilization is bad, causes bacterial infection easily; Simultaneously because the transfusion lumen diameter is more much bigger than guiding wire, guiding wire causes distortion easily in transfusion lumen, the body undercapacity that causes nasogastric tube, nasogastric tube injects in the intravital process of people, body is more easily distortion also, so that the insertion depth error ratio of nasogastric tube is bigger, is difficult to determine whether body arrives stomach, will not continue the preceding action of inserting if body arrives stomach on request, this just increases patient's misery.

Summary of the invention:

The objective of the invention is in order to overcome the shortcoming of above-mentioned prior art, provide that a kind of guiding wire does not directly contact with human body, the nasogastric tube of accurate positioning.

For achieving the above object, technical scheme provided by the invention is: a kind of nasogastric tube that has double lumen, include transfusion lumen, and in body, also be provided with the guidewire lumen that inserts for guiding wire, this guidewire lumen end is a cecum.

The diameter of described guidewire lumen is suitable with the guiding wire diameter.

The advantage of this nasogastric tube is:

By design in the nasogastric tube body one independently, terminal for cecum, offer the guidewire lumen that guiding wire inserts specially, efficiently solve the problem that guiding wire directly contact with juice, the probability of reduction infection;

2. the diameter of guidewire lumen is made quite, can be increased 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.

Description of drawings:

Fig. 1 is the cutaway view after nasogastric tube of the present invention inserts guiding wire;

Fig. 2 is the A-A cutaway view Amplified image of Fig. 1;

Fig. 3 is the structure chart of nasogastric tube of the present invention.

The specific embodiment:

Now 1～accompanying drawing 3 elaborates the present invention in conjunction with the accompanying drawings:

Have the guidewire lumen 3 that is provided with transfusion lumen 1 and inserts in the nasogastric tube body of double lumen for guiding wire 2, these two tube chambers are independent separately, different mutually, transfusion lumen 1 is responsible for the injection of nutritional solution and medicine, guidewire lumen 3 is responsible for holding guiding wire 2, these guidewire lumen 3 ends are cecum, this is just effectively avoided, and guiding wire 2 and patient body are interior directly to be contacted, and the diameter of guidewire lumen 3 is suitable with guiding wire 2 diameters, after guiding wire 2 inserted, the body intensity of nasogastric tube strengthened greatly.

Claims

1. a nasogastric tube that has double lumen includes transfusion lumen (1), it is characterized in that: also be provided with the guidewire lumen (3) that inserts for guiding wire (2), this guidewire lumen (3) end is a cecum.

2. a kind of nasogastric tube that has double lumen according to claim 1 is characterized in that: the diameter of described guidewire lumen (3) is suitable with guiding wire (2) diameter.
