Description

Multi-cavity visible gastrointestinal tube

Technical Field

The utility model belongs to the technical field of the gastrointestinal tube, specific visual gastrointestinal tube of multicavity that says so.

Background

The gastrointestinal tube is used for delivering nutrient substances into the esophagus, the stomach or the duodenum of a patient to provide nutrition, and the cost of the nutrient substances in the intestine or the stomach is greatly lower than that of the nutrient substances infused by intravenous injection, so that the economic burden of the patient can be reduced; the naso-gastric tube is used for providing nutrient solution to intestines, the naso-gastric tube generally comprises a head and a catheter communicated with the head, the catheter is provided with a spiral section connected with the head, the nutrient solution enters the head through the catheter and then flows out through the head and is released into the intestines, the naso-gastric tube is inserted into the stomach through a nasal cavity when in use, the spiral section of the catheter can be stretched under the action of gastrointestinal peristalsis, so that the head is pushed to generate self peristalsis and pass through pylorus automatically, finally, the spiral section stays in the duodenum and jejunum at a position corresponding to a troostite ligament, the nutrient solution is provided to the intestines, so as to reduce intestinal mucosa atrophy and intestinal bacteria translocation caused by insufficient nutrition in the intestines, maintain the intestinal function, in the traditional field, for patients who are in surgery, coma, can not eat in the stomach and the like, the nasal feeding is generally carried out by nasal-gastric tube feeding clinically, the catheter enters the stomach, duodenum or jejunum along the esophagus through the nasal cavity, the catheter is required to have certain hardness and elasticity and is not easy to break for smooth insertion, and lubricants such as liquid paraffin and the like need to be coated on the surface of the catheter, so that time is usually consumed for the insertion of the catheter by a doctor clinically, and the catheter is more difficult to penetrate through the pylorus particularly for a patient to be inserted into the duodenum; for patients who need nasal feeding for a long time, the frequent replacement of the catheter can bring pain to the patients and increase the workload of medical staff.

Currently, the nasal gastrointestinal tube used in clinic mainly has the following defects:

1. the success rate of direct insertion through pylorus is low, the pylorus is required to pass through by virtue of the self-peristalsis of the stomach and intestine or the action of gravity, the pylorus enters duodenum and jejunum, the nutrition part can be reached generally after a long time, and the success rate is low;

2. the existing single-cavity catheter segment has single function, can only carry out feeding or cleaning or perfusion or decompression independently, and can not carry out two operations simultaneously.

SUMMERY OF THE UTILITY MODEL

In order to compensate the not enough of prior art, solve current single chamber pipe section function singleness, only can feed alone or wash or fill or decompress, can not carry out the problem of two kinds of operations simultaneously, the utility model provides a visual gastrointestinal tract of multicavity.

The utility model provides a technical scheme that its technical problem adopted is: the utility model relates to a multi-cavity visible gastrointestinal tube, which comprises a hose; the flexible tube consists of an intestinal tube and a stomach tube, and the bottom end of the flexible tube is a contractive opening; the side walls of the end parts of the intestinal canal and the stomach canal are fixedly connected with small cover openings; a guide wire is arranged in the intestinal canal; and the top end of the guide wire is fixedly connected with a wire cap.

Preferably, the side wall of the gastric tube is provided with a valve hole; a valve clack structure is arranged in the valve hole; the valve clack structure comprises a valve and a valve plate; the valve is fixedly connected to the side wall of the valve hole; the valve plate rigid coupling is on the valve opening lateral wall relative with the valve, and valve plate mutual contact.

Preferably, the gastric tube side wall is provided with a developing line.

Preferably, the stomach tube is provided with a baffle plate at the inner side wall close to the bottom end of the valve clack structure; the intestinal tube is provided with a plurality of notches at the side wall near the bottom end thereof.

Preferably, the stomach tube is symmetrically provided with a first hole on the side wall close to the bottom end of the baffle; a one-way structure is arranged on the first hole.

Preferably, the one-way structure comprises a first sealing plate and a second sealing plate; the first sealing plate and the second sealing plate are symmetrically arranged on the inner side wall of the first hole.

The utility model has the advantages that:

the utility model provides a multi-cavity visible gastrointestinal tube, which realizes the simultaneous implementation of gastrointestinal nutrition delivery and gastrointestinal drainage decompression after arranging an intestinal tube and a gastric tube of independent cavities, thereby relieving the pain of patients in the medical treatment process; meanwhile, the gastric juice can only enter the gastrointestinal tract through the valve hole in one way through the valve clack structure and the first hole, so that the phenomenon that the gastric juice flows back through the valve hole is avoided; when the nutrient solution passes through the notch, because the number of notches is provided with a plurality of to effectively avoid the nutrient solution to produce the jam phenomenon in notch department.
