Description

Technical Field

[0001] The utility model relates to a nasogastric tube, in particular to a novel improved structure of a nasogastric tube. Background Art

[0002] The existing gastric tube interface has only one plug, and there is no anti-disconnection fixer for connecting the nasogastric tube (bag). There is also no air bag to prevent gastric contents from reflux. The defects of the above nasogastric tube are:

[0003] 1. The gastric tube interface connected to the nasogastric feeding tube (bag) has no protective fixator, which is easily disconnected during turning over, and the cost of clinical external fixators is relatively high.

[0004] 2. Patients with indwelling gastric tubes are very prone to retrograde reflux of gastric contents, which may cause the reflux to enter the trachea and cause lung infection.

[0005] In summary, the utility model designs a novel improved structure of a nasogastric tube. Summary of the invention

[0006] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a new improved structure of nasogastric tube, which has a reasonable structural design, is easy and reliable to use, and can prevent retrograde reflux of gastric contents that causes reflux to enter the trachea by mistake and cause lung infection.

[0007] In order to achieve the above-mentioned purpose, the utility model is realized through the following technical scheme: a new improved structure of nasogastric tube, including a nasogastric tube body, a positive pressure joint and a reflux air bag, the tail end of the main channel of the nasogastric tube body is provided with a positive pressure joint, the front end of the nasogastric tube body is provided with a reflux air bag, and the reflux air bag is connected to the air bag inflation port.

[0008] Preferably, the positive pressure connector comprises a positive pressure connector body, a fixing buckle, a fixing rope and a nasogastric tube bag interface, one end of the positive pressure connector body is connected to the tail end of the nasogastric tube body, the other end of the positive pressure connector body is connected to the nasogastric tube bag interface, the nasogastric tube bag interface is externally connected to the nasogastric tube bag, the fixing buckle is connected to the positive pressure connector body by a fixing rope, and the fixing buckle is clamped and fixed to clothes.

[0009] The utility model has the following beneficial effects:

[0010] 1. The positive pressure connector facilitates the injection of nasogastric feeding fluid, is less likely to cause damage to gastric contents, and is easier to clean.

[0011] 2. Leave a fastener to fix the interface and prevent it from coming off when using the nasogastric feeding bag. After nasogastric feeding, fix the buckle on the clothes to prevent the tail end of the gastric tube from swinging at will.

[0012] 3. An air bag is set at the front end (with an appropriate amount of gas, and the volume of the air bag is slightly larger than the cardia) to reduce gastric peristalsis and the reflux of gastric juice and food in the stomach. It is more conducive to preventing the retrograde reflux of gastric contents, which causes the reflux to enter the trachea by mistake and cause lung infection. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods;

[0014] Figure 1 It is a schematic diagram of the structure of the utility model;

[0015] Figure 2 It is a structural schematic diagram of the positive pressure joint of the utility model. Implementation

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0017] Reference Figure 1-2 The present specific implementation adopts the following technical scheme: a novel improved structure of a nasogastric tube, comprising a nasogastric tube body 1, a positive pressure connector 2 and a reflux airbag 3. The tail end of the main channel of the nasogastric tube body 1 is provided with a positive pressure connector 2, and the front end of the nasogastric tube body 1 is provided with a reflux airbag 3, which is connected to the airbag inflation port 4.

[0018] It is worth noting that the positive pressure connector 2 includes a positive pressure connector body 21, a fixing buckle 22, a fixing rope 23 and a nasogastric tube bag interface 24. One end of the positive pressure connector body 21 is connected to the tail end of the nasogastric tube body 1, and the other end of the positive pressure connector body 21 is connected to the nasogastric tube bag interface 24. The nasogastric tube bag interface 24 is externally connected to the nasogastric tube bag. The fixing buckle 22 is connected to the positive pressure connector body 21 through the fixing rope 23, and the fixing buckle 22 is clamped and fixed to the clothes.

[0019] This specific implementation adds a positive pressure connector to facilitate the injection of nasogastric feeding liquid, and is not likely to cause gastric contents to be damaged, and is easier to clean. A fixer is also added to prevent the interface from being disengaged when using the nasogastric feeding bag. After the nasogastric feeding is completed, the buckle is fixed on the clothes to prevent the tail end of the gastric tube from swinging at will. An air bag is placed at the front end (with an appropriate amount of gas, and the volume of the air bag is slightly larger than the cardia) to reduce gastric peristalsis and the reflux of gastric juice and food in the stomach. It is more conducive to preventing retrograde reflux of gastric contents, causing the reflux to enter the trachea by mistake and cause lung infection.

[0020] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model.
