Description

A device for preventing blockage of nasointestinal tube

technical field

The utility model relates to the technical field of medical feeding tube instruments, in particular to an anti-blocking naso-intestinal tube placement device.

Background technique

Generally, patients who cannot eat by mouth often use enteral nutrition support. Enteral nutrition includes three methods: intragastric tube feeding, duodenal tube feeding and jejunal tube feeding, unless the patient has gastric emptying disorder or is not suitable for the stomach Intragastric tube feeding is generally preferred, and nasointestinal tube is generally preferred for tube feeding, but the lumen of the nasointestinal tube is narrow, and the nutrient solution is viscous and high in concentration, resulting in the gradual accumulation of drugs, food and nutrient solution on the wall, which is easy to block the tube In order to prevent the blockage of the nutrient tube, the existing technology is to give warm water to rinse and lubricate the lumen before each injection of nutrient solution, and then use it after use. Rinse the remaining nutrient solution in the lumen with warm water. When the lumen is blocked, generally use warm water to flush the blockage. However, it often happens that the lumen is sealed by the nutrient solution, and the warm water cannot dredge the situation. At this time, it is necessary to Re-insertion of the nasointestinal tube increases the pain of patients and increases the economic burden.

Utility model content

In view of the above situation, in order to overcome the defects of the prior art, the purpose of the present utility model is to provide an anti-blocking nasoenteric tube device, which effectively solves the problem that the existing nasointestinal tube cannot be dredged by warm water and increases the pain of the patient.

The technical solution is that the utility model includes a left and right axial indwelling tube, the right end of the indwelling tube is coaxially provided with a fixed tube, the left end of the indwelling tube is coaxially provided with a liquid discharge cylinder, and the left end of the liquid discharge cylinder is provided with a left and right through liquid outlet. The inner side wall of the indwelling tube is coaxially provided with a balloon, and the right end of the outer edge of the indwelling tube is provided with a connecting tube which is axially up and down and communicated with the inside of the balloon. The gas cylinder is coaxially provided with a T-shaped piston rod which can slide left and right.

Compared with the prior art, the beneficial effects of the present utility model are: filter the nutrient solution by setting a filter tube and then inject it into the indwelling tube to prevent coarse substances from entering the indwelling tube; The pressure to clear the blockage in the indwelling tube is convenient for medical staff to clear the indwelling tube, which helps to reduce the pain of the patient and enables the patient to recover normally.

Detailed ways

The specific embodiments of the present utility model will be further described in detail below with reference to the accompanying drawings.

1 to 4, including the left and right axial indwelling tube 1, the right end of the indwelling tube 1 is coaxially provided with a fixed tube 2, the left end of the indwelling tube 1 is coaxially provided with a liquid discharge cylinder 3, and the left end of the liquid discharge cylinder 3 is provided with a The left and right penetrating liquid outlet holes 4, the inner side wall of the indwelling tube 1 is coaxially provided with an airbag 5, the right end of the outer edge surface of the indwelling tube 1 is provided with a connecting tube 6 which is axially up and down and communicates with the interior of the airbag 5, and the connecting tube 6 is disassembled and connected inside There is a duct 7, the right end of the duct 7 is fixed with a left and right axial gas cylinder 8, and the gas cylinder 8 is coaxially provided with a T-shaped piston rod 9 that can slide left and right.

In order to control the sliding of the piston rod 9 in the gas cylinder 8, a blocking ring 10 is coaxially provided on the right side of the gas cylinder 8, the blocking ring 10 is protruded from the right end of the piston rod 9, and a connecting plate 11 is coaxially provided, and the front end of the connecting disk 11 is fixed There is an L-shaped sliding handle 12 , and the sliding handle 12 can slide left and right on the gas cylinder 8 .

In order to facilitate the piston rod 9 to slide left and right in the gas cylinder 8 , the piston rod 9 is sheathed with a spring 13 located between the blocking ring 10 and the connecting plate 11 .

In order to reduce coarse substances in the nutrient solution and reduce the risk of clogging the indwelling tube 1 , a filter tube 14 is threadedly connected to the right end of the fixed tube 2 , and a filter screen 15 is coaxially arranged in the filter tube 14 .

In order to prevent backflow of the nutrient solution from the indwelling tube 1 , the fixed tube 2 is provided with a one-way valve 16 whose opening faces the indwelling tube 1 .

In order to facilitate the disassembly of the conduit 7 and the connecting pipe 6 to close the connecting pipe 6 , the left end of the connecting pipe 6 is provided with an elastic band 17 , and the free end of the elastic band 17 is fixed with a rubber plug 18 that can be inserted into the connecting pipe 6 .

When the utility model is in use, its initial state is that the left end face of the blocking ring 10 is in contact with the right end face of the piston rod 9, the fixed tube 2 is not in contact with the filter tube 14, the nutrient solution is injected by a syringe, and the conduit 7 is not in contact with the connecting tube 6. The rubber plug 18 is located in the connecting pipe 6;

After the left end of the filter tube 14 is connected with the fixed tube 2, the syringe is connected with the right end of the filter tube 14, the nutrient solution is injected into the filter tube 14 through the syringe, and the filter screen 15 in the filter tube 14 filters the coarse material in the nutrient solution to prevent clogging Indwelling tube 1, the one-way valve 16 is opened, the filtered nutrient solution flows into the indwelling tube 1 through the fixed tube 2, the nutrient solution flows into the drainage tube 3 from the indwelling tube 1, and flows into the patient's gastrointestinal tract through the liquid outlet hole 4. When the nutrient solution flows back from the stomach, the one-way valve 16 in the fixed tube 2 is closed to prevent the nutrient solution from flowing back from the fixed tube 2;
