Description

Novel stomach tube intubation structure

Technical Field

The invention relates to the field of medical instruments, in particular to a novel stomach tube intubation structure.

Background

Gastric tube intubation is widely used in modern medical activities, and the prior art gastric tube is a section of silicone hose or rubber hose. In application, the product is inserted from nasal cavity or oral cavity of patient, and delivered to stomach via pharynx and esophagus. Patients who cannot eat food autonomously or need gastrointestinal decompression need to be subjected to indwelling gastric tube intubation clinically. Through the indwelling stomach tube intubation, not only can liquid food or enteral nutrient solution be fed to the stomach of a patient who cannot eat food autonomously, necessary energy and nutrition are provided for the patient, but also gas and liquid accumulated in the gastrointestinal tract can be sucked out.

Because the gastric tube must pass through the pharynx and esophagus to enter the stomach, the gastric tube is bent. The food fed into the stomach of the patient is processed into pasty food, but the food is still easy to cause blockage at the bending part of the gastric intubation. At present, it is common practice to pour water or neutralize the liquid, thereby removing the food that has caused the blockage. However, the impulsive force of water is comparatively small, and the blockage of food is generally difficult to remove. The neutralizing liquid is in contact with only the end of the clogged food, so that it is difficult to remove the clogged food.

The designer deeply conceives the problems existing in the use of the gastric tube intubation and actively develops and tests to generate the scheme.

Detailed Description

As shown in fig. 1 to 3, the present invention discloses a novel gastric tube intubation structure, which includes an intubation body 10, wherein a first channel 11 and a second channel 12 which are isolated from each other are formed in the intubation body 10, and the first channel 11 penetrates through the intubation body 10 in the length direction of the intubation body 10; the intubation tube is characterized in that an air bag 20 is connected in the intubation tube body 10, the air bag 20 is located in the first channel 11 and is matched with the intubation tube body 10 to form an air bag chamber 21, the air bag chamber 21 is communicated with the second channel 12 and is isolated from the first channel 11, and the air bag 20 is attached to the inner side of the intubation tube body 10 in the state that the air bag chamber 21 is not inflated.

After the gastric tube intubation is inserted into the stomach from the nasal cavity or the oral cavity of a patient, no gas exists in the air bag chamber 21 under a normal state, and the air bag 20 is generally tightly attached to the inner side of the intubation body 10. The balloon chamber 21 will only be inflated if the patient is fed through the gastric tube cannula and a blockage occurs. Specifically, when the food jam occurs, the balloon chamber 21 is inflated through the second passage 12, and after the balloon chamber 21 is filled with air, the balloon 20 expands toward the inside of the cannula body 10, thereby squeezing the pasty food, which is spread toward both ends after being squeezed. Then, the air in the air bag chamber 21 is evacuated, the air bag 20 is attached to the cannula body 10, and a gap is formed between the food and the cannula body 10. At this time, the food naturally flows into the stomach of the patient. If the food is still clogged at this time, water or a neutralizing liquid may be poured in, and since there is a gap between the food and the cannula body 10, water may enter the gap, thereby bringing the food to the stomach of the patient. Also, since there is a gap between the food and the cannula body 10, the neutralizing liquid can permeate into the gap to react with the food, and since the contact area between the food and the neutralizing liquid is increased, the food can flow like the back of the patient after being processed, thereby solving the problem of food blockage. When food blockage occurs in the stomach tube intubation, the problem of food blockage can be quickly solved only by inflating the air bag cavity 21 through the second channel 12 and then deflating, the stomach tube intubation does not need to be pulled out, and the operation is simple and convenient.

In this embodiment, only one balloon 20 is disposed within the cannula body 10, forming a balloon chamber 21. In practical use, in order to further increase the flushing force of the water flow or increase the contact area between the neutralizing liquid and the food, a plurality of air bags 20 may be disposed in the cannula body 10 to form a plurality of air bag chambers 21, and the plurality of air bag chambers 21 are connected to the second channel 12. Each balloon 20 may be disposed along the length of the cannula body 10.

In order to solve the problem of food blockage more quickly, the second channel 12 is communicated with the balloon chamber 21 at the stomach tube end 14, wherein the stomach tube end 14 is the end opposite to the external end 13, and the external end 13 is the end of the cannula body 10 matched with the outside. The length of the airbag chamber 21 is equal to or less than the length of the first passage 11. In this embodiment, the airbag chamber 21 is of equal length to the first passage 11. Since the food blockage problem is likely to occur in other parts besides the bent part of the gastric tube insertion tube, the balloon chamber 21 is set to be as long as the first channel 11, so that the food blockage problem occurring in each part of the insertion tube body 10 can be effectively solved.

In order to inflate the airbag chamber 21, the second channel 12 is connected to an inflation/deflation tube 31, one end of the inflation/deflation tube 31 is connected to the second channel 12, and the other end is connected to a check valve 32. The one-way valve 32 can prevent the air bag chamber 21 from air leakage in the inflated state, and can prevent external air from entering the air bag chamber 21 in the uninflated state of the air bag chamber 21, so that the air bag 20 can be always attached to the inner side of the cannula body 10, and thus, the air bag 20 can not influence the food flow.

In summary, the key point of the present invention is that the balloon 20 is arranged in the cannula body 10 of the gastric tube cannula, and the balloon chamber 21 is formed between the balloon 20 and the cannula body 10. Under the normal state, the air bag 20 is tightly attached to the inner side of the intubation tube body 10, and the normal use of the gastric tube intubation is not influenced; under the condition that food is blocked, the air bag chamber 21 is inflated, the air bag 20 expands inwards to squeeze food, the food is squeezed to diffuse towards two ends, then the air in the air bag chamber 21 is pumped out, the air bag 20 is attached to the intubation tube body 10, and a gap is formed between the food and the intubation tube body 10. At the moment, food can naturally flow into the stomach of the patient, or the food is brought to the stomach of the patient under the action of water or neutralizing liquid, so that the problem of food blockage is quickly solved, and the operation is simple and convenient.

The above description is only exemplary of the present invention and is not intended to limit the technical scope of the present invention, so that any minor modifications, equivalent changes and modifications made to the above exemplary embodiments according to the technical spirit of the present invention are within the technical scope of the present invention.
