Problems solved by technology

But because the guide wire of this tube body does not fully extend into the end of the tube body, in the process of inserting into the human body, or when staying in the human body, a section of tube body with a side hole at the front end will be folded, resulting in failure. Smooth intubation, serious may affect the flow of the side hole, or block the tube body

Embodiment

[0017] Example: see Figure 1-Figure 3 , a double-lumen nasogastric tube, including a tube body and a barrier, the barrier extends along the length of the tube body to separate the tube body into double lumens, one of the two lumens is a guide wire lumen, and the other is an infusion tube One end of the guide wire cavity is open, and the other end is a blind end. A section of support body is arranged in the blind end. The infusion chamber has several side holes at the blind end. The length of the support body is the same as the length of the distribution of the side holes. match.

[0018] The tube body is a cylindrical tube body, the guide wire lumen is a cylindrical tube body, and the cylindrical tube body of the guide wire lumen is cut into the cylindrical tube body of the tube body.

[0019] The cross-sectional shape of the interlayer is arc-shaped.

[0020] The diameter of the guide wire lumen matches the diameter of the support body.

[0021] One end of the supporting ...

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 [0001] The invention relates to the technical field of medical devices, in particular to a double-chamber nasogastric tube. Background technique [0002] The traditional design of the nasogastric tube body is generally single lumen, and the guide wire is located in the lumen. Since the diameter of the guide wire is much smaller than the inner diameter of the lumen, the support of the guide wire to the nasogastric tube is not in an optimal state. In the process of inserting the nasogastric tube into the human body, the guide wire is easily twisted, which is not conducive to the smooth entry of the tube into the human body; in recent years, a double-lumen nasogastric tube has emerged, such as the invention patent of Chinese patent 200910037178.2, which discloses a A kind of nasogastric tube with double lumens, including an infusion lumen, and a guide wire lumen for inserting a guide wire is also arranged in the tube body, the end of the guide wire lumen is ...
