Description

Technical Field

[0001] The utility model belongs to the technical field of medical equipment, and in particular relates to a gastrojejunostomy nutrition tube. Background Art

[0002] For patients with head and neck and esophageal malignant tumors who have eating disorders and normal gastrointestinal function and require long-term tube feeding; patients with neurological diseases such as stroke, amyotrophic lateral sclerosis and brain trauma; patients with cancerous gastrointestinal obstruction; patients with pancreatitis or Crohn's disease who are intolerant to oral administration and require long-term tube feeding; patients with other diseases such as benign esophageal stenosis, tracheoesophageal fistula, gastric emptying disorder, short bowel syndrome and severe malnutrition, gastric and jejunal nutrition tubes need to be implanted to establish a long-term enteral nutrition support (EN) channel for nutritional support or drug treatment.

[0003] Gastrojejunostomy offers a relatively safe and effective minimally invasive surgical approach. It has good compliance and can reduce the incidence of reflux and aspiration pneumonia. Surgical jejunostomy can be achieved through open surgery, including tunnel jejunostomy (Witzel jejunostomy), Roux-en-Y jejunostomy, and needle-catheter jejunostomy (NCJ), as well as through open gastric jejunostomy and laparoscopic surgical jejunostomy. However, standardized technical guidelines and uniform, standard feeding tube materials are still lacking.

[0004] A gastrojejunostomy feeding tube is a medical device used for feeding and nutritional support, or to help patients eliminate gas and fluids from their stomach and intestines. This device is typically made of flexible, corrosion-resistant materials for safe use within the patient's body. One end of the feeding tube is inserted into the stomach or intestine, while the other end is connected to an external container for the injection of chyme or medication.

[0005] When in use, the base design of existing nutrition tubes often uses glue to fix to the patient's skin. This method is easily affected by factors such as skin type, humidity, and temperature, resulting in unstable bonding effects and even displacement or falling off. In addition, the existing glue-attachment method may cause inconvenience to patients when wearing protective equipment or performing daily activities. At the same time, the adhesive may cause irritation or allergic reactions to the skin.

[0006] Existing feeding tubes often have complex shapes and structures, with numerous redundant tubes outside the peritoneal cavity, making them difficult to use and maintain. The use of urinary catheters, fungiform tubes, and other alternatives to feeding tubes during fistula ostomy procedures is common. Therefore, a new type of feeding tube with reliable fixation, simple structure, and practicality is urgently needed. Utility Model Content

[0007] The purpose of the utility model is to provide a gastrojejunostomy nutrition tube, aiming to solve the problems in the prior art of nutrition tubes, such as complex structure, lengthy extracorporeal tubing, and difficulty in nursing and use; and the base design is often fixed to the patient's skin by gluing, which is easily affected by factors such as skin type, humidity, and temperature, resulting in unstable bonding effect and even displacement or falling off. In addition, the existing gluing method may cause inconvenience to patients when wearing protective equipment or performing daily activities. At the same time, the adhesive may cause irritation or allergic reaction to the skin.

The number and distribution of the nutrient holes 6 can be optimized according to the anatomical characteristics of the stomach and intestines and the specific conditions of the patient to improve nutritional efficiency. And in order to facilitate implantation and removal, the base 1 can be designed as a detachable structure so that it can be easily removed or re-fixed from the inner wall of the stomach and intestine. In addition, the base 1 can also be equipped with a guide device to help the nutrient tube correctly locate to a predetermined position during implantation.

[0038] For details, please refer to Figure 3 A one-way valve 11 is fixedly connected to the upper tube 2 , and the one-way valve 11 is built into the lower tube 5 .

[0039] In this embodiment, one-way valve 11 allows nutrient solution to flow from the upper tube into the stomach and intestines, but prevents reverse flow, thereby ensuring that the contents of the tube can only be injected and not expelled. One-way valve 11 is built-in, its structure aligning with the inner wall of upper tube 2 without adding any additional external connections, thereby reducing the risk of leakage and improving the stability of the overall structure.

[0040] For details, please refer to Figure 1 and Figure 2 The upper end of the base 1 is fixedly connected to the limit seat 10, and the limit seat 10 matches the rotating cover 8.

[0041] In this embodiment: the limit seat 10 is matched with the rotating cover 8. This design allows the rotating cover 8 to be fastened to the base 1 by rotation, forming a firm connection to prevent the nutrition tube from moving or falling off in the stomach and intestines. The shape and size of the limit seat 10 can be designed to be compatible with the thread of the rotating cover 8 to ensure that the rotating cover 8 can be stably rotated and fastened on the base 1. This threaded connection method can provide medical staff with a simple and effective tool for adjusting the flux of the nutrition tube and monitoring the nutritional status. In this embodiment, the design of the limit seat 10 can include a cuttable structure to match the interface of external equipment such as a ventilator, nutrition pump or nutrition bag. This design allows the limit seat 10 to be cut according to the thread size of the external equipment to ensure the precise connection of the nutrition tube to the external equipment.

[0043] In this embodiment, the graduated lines 7 can be positioned according to the specific patient needs. This design allows medical staff to adjust the position of the feeding tube during or after surgery based on the patient's specific condition to ensure maximum nutritional benefits. The graduated lines 7 can be marked at specific locations on the feeding tube, for example, corresponding to specific gastrointestinal locations such as the fundus, the beginning of the small intestine, or the end of the large intestine. This allows medical staff to accurately determine the position of the feeding tube within the stomach, allowing for better nutritional control.

[0044] For details, please refer to Figure 1 and Figure 2 An arc-shaped opening 3 is provided at the upper end of the base 1 and arranged in an array along the circumference of the base 1. The arc-shaped opening 3 enables the base 1 to adhere flexibly to the skin.

[0045] In this embodiment: an arc-shaped opening 3 is provided at the upper end of the base 1. The design of this arc-shaped opening 3 can provide multiple advantages to improve the functionality of the nutrition tube and the comfort of the patient. The shape and size of the arc-shaped opening 3 can be carefully designed to make it easier for medical staff to operate when inserting or removing the nutrition tube. For example, the arc-shaped opening 3 can be designed into an ergonomic curve so that the medical staff's fingers can be placed and operated more naturally. The arc-shaped opening 3 can also reduce the inconvenience of patients when wearing protective equipment. Due to the presence of the arc-shaped opening 3, medical staff can access the nutrition tube without completely removing the protective equipment, thereby improving the convenience and safety of operation.

[0046] For details, please refer to Figure 1 and Figure 2 The upper end of the rotating cover 8 is fixedly connected with an anti-slip sleeve 12, and the anti-slip sleeve 12 is sleeved on the upper tube 2.

[0047] In this embodiment, a non-slip sleeve 12 is fixedly attached to the upper end of the rotating cover 8. This design offers multiple advantages, enhancing the functionality of the feeding tube and patient comfort. The non-slip sleeve 12 can be made of a material with good friction, such as silicone or rubber, providing sufficient grip and ensuring greater stability and reliability for medical personnel when operating the rotating cover 8.

[0048] The working principle and usage process of the present invention are as follows: First, during the operation, the doctor will implant the nutrition tube into the patient's body according to the patient's specific situation, so that the base 1 is in close contact with the skin. The arc-shaped opening 3 on the base 1 is designed so that the base 1 can better fit the skin and improve the patient's comfort. The doctor will operate the rotating cover 8 through the anti-slip sleeve 12 on the rotating cover 8 to facilitate the management or adjustment of the nutrition tube. If it is necessary to suture the base 1 and the skin, the doctor will use sutures to suture through the suture hole 4 opened on the base 1. The design of the suture hole 4 makes the suturing process more convenient and also ensures the stability of the suture. After the operation is completed, the patient can live and move normally, and the nutrition tube will continue to work to monitor and nourish the substances in the gastrointestinal tract. Medical staff will regularly check the nutrition tube, observe the nutritional status, and take appropriate measures as needed.

[0049] The above examples illustrate the use of this solution and the function of suture holes 4. The design of suture holes 4 allows for effective suture of the base 1 to the skin, ensuring the stability of the feeding tube and patient comfort. Furthermore, the design of the arcuate opening 3 allows the base 1 to better conform to the skin, improving patient comfort.
