Abstract

A separable nasogastrointestinal tube, comprising a gastric tube (1) and an intestinal tube (2), an arc-shaped groove (11) accommodating the intestinal tube (2) extending along the length of the outer wall of the gastric tube (1), the intestinal tube (2) being embedded within said groove (11). When used, as the intestinal tube (2) of the present separable nasogastrointestinal tube is embedded within the arc-shaped groove (11) of the gastric tube (1), the gastric tube (1) and the intestinal tube (2) can be inserted simultaneously into the human body, and the gastric tube (1) can be retracted separately, thereby mitigating patient discomfort.

Description

Separable nasal gastrointestinal tube

Technical field

The present invention relates to a medical device, and in particular to a nasal gastrointestinal tube.

Background technique

Nasal stomach and intestine are devices for injecting nutrients into the gastrointestinal tract through the nasal cavity or oral cannula. The existing intestines and stomach tubes are single-lumen or single-lumen gastric tubes. The patient usually needs to insert a single cavity before surgery or when feeding nutrition. Intestinal tube and single-lumen stomach tube were used for enteral nutrition and gastric decompression, respectively. The intestine and stomach tube were inserted twice to bring great pain to the patient.

Summary of the invention

SUMMARY OF THE INVENTION It is an object of the present invention to provide a separable nasal gastrointestinal catheter which is easy to use and which relieves the suffering of the patient during intubation.

In order to achieve the above object, the technical solution of the present invention is: a separable nasal gastrointestinal tube comprising a stomach tube and an intestine tube, wherein the outer wall of the stomach tube is provided with an arcuate groove extending in the longitudinal direction for accommodating the intestine tube, and the intestine tube is stuck Inside the curved groove.

The invention can separate the nasal gastrointestinal tube, wherein the stomach tube is provided with a plurality of balloons in the longitudinal direction, each of the balloons is made of an elastic material, the balloon is sleeved on the stomach tube and the balloon is removed The corresponding portions of the curved groove are closely adhered to the outer wall of the stomach tube, and the tightly fitting portion forms a sealing layer, and an expansion cavity is formed between each balloon and the outer wall of the curved groove, and the length along the side wall of the stomach tube is provided In the direction of extending the inflation chamber, the inflation chamber is connected with an inflation tube joint, the inflation tube joint is located outside the stomach tube, and the sealing layer is provided with a plurality of ventilation holes for respectively connecting the inflation chamber and each expansion chamber.

After adopting the above scheme, the invention can separate the nasal gastrointestinal tube. Since the intestinal tube is stuck in the curved groove of the gastric tube, the stomach tube and the intestinal tube can be simultaneously put into the human body at the same time, which is convenient to use and relieves the suffering of the patient.

In addition, since the balloon is provided on the stomach tube, the balloon can be extruded into the arc groove after inflation, so that the gastric tube can be taken out after the gastric decompression is completed, because the stomach tube is thick, the stomach tube can be greatly removed. Relieve the pain of patient intubation.

detailed description

As shown in Fig. 1, the separable nasal gastrointestinal tube of the present invention comprises a gastric tube 1 and an intestinal tube 2, as shown in Fig. 2 and Fig. 2a, the gastric tube 1 The outer wall is provided with an arcuate groove 11 extending in the longitudinal direction for accommodating the intestinal tube 2. The stomach tube 1 is sequentially provided with a plurality of balloons 3 in the longitudinal direction, the balloon 3 is made of an elastic material, and the balloon 3 is placed on the stomach. On the tube 1, the portion of the balloon 3 except the portion corresponding to the curved groove 11 is welded or bonded to the outer wall of the stomach tube 1, and the welded or bonded portion forms the sealing layer 5, the balloon 3 and the curved groove 11 An inflation chamber 31 is formed between the outer walls. The side wall of the stomach tube 1 is provided with an inflation chamber 4 extending in the longitudinal direction. The inflation chamber 4 is connected with an inflation tube joint 41. The inflation tube joint 41 is located at the stomach tube 1 and the sealing layer 5 A plurality of vent holes 12 are provided for communicating the inflation chamber 4 with the respective expansion chambers 31, and the intestines 2 are caught in the arcuate grooves 11.

When in use, the intestine 2 is first caught in the arcuate groove on the stomach tube 1, as shown in Fig. 1, the separable nasal gastrointestinal tube is placed in the human body, and when the gastric decompression is completed, the inflatable tube joint 41 is passed. Inflating into the inflation chamber 4, the charged gas enters the expansion chamber 31 of each balloon 3 through the vent hole 12, so that the balloons bulge as shown in Figs. 3 and 4, and the intestinal tube 2 is extruded into the arc groove 11 Bu, stop inflating, after the balloon 3 is contracted, the stomach tube 1 is pulled out from the human body, leaving only the intestine 2 to provide nutrition.

The above described embodiments are merely illustrative of the preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Modifications and improvements are intended to fall within the scope of the invention as defined by the appended claims.
