Description

Technical Field

[0001] The present application belongs to the technical field of medical supplies, and in particular relates to a gastrointestinal nutrition tube. Background Art

[0002] As an important means of enteral nutrition support, nasogastric feeding tube technology has been widely used in clinical practice. This technology uses endoscopy or manual methods to place a feeding tube into the patient's gastrointestinal tract to provide the patient with necessary nutritional support.

[0003] 1. Medical nutritional support

[0004] Patients who are unable to eat for a long time: For patients who are unable to eat on their own for a long time due to chronic diseases, serious illnesses (such as advanced cancer), postoperative recovery, or other reasons, nasogastric feeding tube technology provides an effective means of nutritional support. By delivering liquid diet or nutrient solution, it can meet the energy and nutrient needs of the patient's body and maintain their life activities.

[0005] Malnourished patients: During medical treatment, some patients may experience malnutrition, which can affect their recovery. Nasogastric feeding tube technology can directly provide patients with high-concentration nutrients, improving their nutritional status and accelerating recovery.

[0006] 2. Rehabilitation

[0007] Patients in recovery: During the recovery period, especially for those who need to stay in bed for a long time or have limited activities, nasogastric feeding tube technology can provide stable nutritional support, which helps the body recover and rebuild functions.

[0008] Special rehabilitation needs: For patients with special rehabilitation needs, such as those with swallowing dysfunction, nasogastric feeding tube technology can be used as an auxiliary means to help them maintain nutritional intake and promote recovery.

[0009] 3. Temporary Diet Replacement

[0010] Fasting before surgery: In some cases where fasting is required before surgery, nasogastric feeding tube technology can ensure that patients continue to obtain necessary nutrients before surgery and avoid malnutrition caused by fasting.

[0011] Emergency situations: In special circumstances such as natural disasters and emergency rescue, when regular diet cannot be guaranteed, nasogastric feeding tube technology can temporarily replace regular oral diet to provide necessary nutritional support for trapped or injured people.

[0012] 4. Intragastric Administration: Nasogastric feeding tubes can also be used to deliver medications to the stomach. This method is suitable for patients who cannot take medication orally or require prolonged medication administration, such as those with dysphagia and gastrointestinal diseases. Administration through a nasogastric tube ensures that medications reach the affected area accurately and promptly, improving treatment efficacy.

[0013] 5. Special examinations and treatments

[0014] Intestinal preparation: Before undergoing certain special examinations (such as gastroscopy, colonoscopy, etc.) or treatments (such as intestinal surgery), a nasogastric feeding tube can be used for intestinal preparation. By infusing special liquids (such as detergents) to clean the intestines, the accuracy and safety of the examination or treatment can be improved.

[0015] Jejunal nutrition: For some special cases (such as pancreatic disease, small intestinal obstruction, etc.), the nasogastric feeding tube can be further extended to the jejunum for nutritional support to bypass the damaged intestinal area and ensure the absorption and utilization of nutrients.

[0016] Existing nasogastric feeding tubes often face problems such as nutrient solution reflux, aspiration, and inconvenient tube fixation during use, affecting patient comfort and safety. At the same time, problems such as non-adjustable tube length, poor filtration effect, and inconvenient drug administration also need to be urgently addressed. Tube fixation is also a significant issue. Existing fixation methods simply use adhesive tape to stick the exposed tube to the face, which can make it difficult to remove or uncomfortable to wear for a long time.

[0017] The present invention aims to provide a tailorable and fixed nasogastric feeding tube system with double filtering air bags, reasonable design, simple operation, safety and reliability, and anti-reflux and anti-aspiration, so as to solve the deficiencies in the prior art.

The ear band is hung on the ear and the restraint band is tightened at the same time, forcing the sleeve to retract and firmly wrap the nasogastric tube therein, thereby achieving reliable fixation of the nasogastric tube.

[0019] In order to solve the technical problem of the inconvenience of using adhesive tape to fix nasogastric feeding tubes in the prior art, the present application provides a gastrointestinal nutrition tube, which includes a fixing cover and a nasogastric feeding tube; the fixing cover includes an elastic cloth belt, a restraining belt and two ear straps, the two ear straps are respectively installed at the two ends of the elastic cloth belt, the elastic cloth belt has a hollow interlayer, a through-opening is opened in the center of the elastic cloth belt, the restraining belt is built into the hollow interlayer, the two ends of the restraining belt are respectively connected to the two ear straps, the middle section of the restraining belt is led out to the outside of the elastic cloth belt through the through-opening to form a sleeve; the nasogastric feeding tube is inserted into the sleeve.

[0020] Furthermore, the present application provides a gastrointestinal nutrition tube, wherein the ear strap includes a drawstring strap and a fixing strap; the inner end of the drawstring strap is connected to the restraining strap, and a plurality of stop balls are arranged at intervals on the outer end; the inner end of the fixing strap is connected to the elastic cloth strap, and a ball sleeve is arranged on the outer end, and the size of the ear strap can be adjusted by adjusting the fit between each stop ball and the ball sleeve.

[0021] Furthermore, the present application provides a gastrointestinal nutrition tube, wherein a sponge block is glued to the outer surface of the elastic cloth belt, and a slot is obliquely provided on the surface of the sponge block.

[0022] Furthermore, the present application provides a gastrointestinal nutrition tube, wherein the nasogastric feeding tube includes a three-way tube and a main tube; the three-way tube includes a nutrient solution injection port, a drug injection port and a quick-connect tube-through port, the outer end of the main tube is inserted into the quick-connect tube-through port, and several through holes are opened on the inner end side wall; the main tube is sequentially provided with an anti-aspiration airbag and an anti-reflux airbag from the outside to the inside, and also includes two tracheas, the two tracheas are integrally formed with the outer side wall of the main tube, and the inner ends of the two tracheas are respectively connected to the anti-aspiration airbag and the anti-reflux airbag.

[0023] Furthermore, the present application provides a gastrointestinal nutrition tube, wherein the outer section of the main tube is engraved with a plurality of cutting marks at intervals, and each of the cutting marks is marked with a distance from the inner end of the main tube.

[0024] Furthermore, the present application provides a gastrointestinal nutrition tube, which also includes a filter membrane. The filter membrane covers the outer tube opening of the main tube and is inserted into the quick-connect tube opening along with the main tube.

[0025] Compared with the existing technology, the present application has the following advantages: 1. Reliable fixation: the original ear-band fixing structure hangs the ear band on the ear while tightening the restraint band, forcing the sleeve to retract and firmly wrap the nasogastric tube therein, thereby achieving reliable fixation of the nasogastric tube; 2. High safety: the double airbag design effectively prevents reflux and aspiration, improving patient safety; 3. Good comfort: the cuttable pipeline design reduces patient discomfort; 4.
