Description

Technical Field

[0001] This utility model relates to the field of medical devices, specifically to a device for inserting a nasogastric tube traction nasojejunal feeding tube. Background Technology

[0002] Nasojejunal feeding tubes are primarily made of silicone. Inserted through the nasal cavity, they pass through the pharynx, esophagus, and stomach, eventually reaching the duodenum or jejunum. This tube is used for enteral nutrition, ensuring patients receive sufficient energy, protein, and other nutrients to meet their nutritional and therapeutic needs and promote recovery. Nasogastric tubes, primarily made of polyurethane, rubber, or silicone, are inserted directly into the stomach through the nasal cavity and are mainly used for gastrointestinal decompression or short-term nutritional support.

[0003] The Fulekai nasoenteric tube is made of polyurethane, a flexible and easily bendable material with a spiral design at the end that automatically fixes itself in the jejunum, reducing displacement and possessing a memory function. The tube's tip has a 2.5-turn ring to aid in positioning within the stomach. However, its flexible material and spiral design result in a low success rate for Fulekai nasoenteric tube placement. A search revealed Chinese patent CN213527055U, which discloses an integrated spiral nasoenteric tube and gastric tube device. Several connecting tubes are attached to the nasoenteric tube and gastric tube bodies. These connecting tubes are made of a water-soluble material and have a cylindrical structure, seamlessly integrated with the nasoenteric tube and gastric tube bodies.

[0004] The existing technology has the following problems: the two openings of the nasojejunal feeding tube and the nasogastric tube are side by side, resulting in a large size, which leads to a low success rate of tube insertion when inserted into the nostril. At the same time, the separation of the two tubes depends on the water-soluble material of the connecting tube and cannot be separated at any time as needed. Utility Model Content

[0005] To address the aforementioned problems, this utility model aims to provide a nasogastric tube traction nasojejunal feeding tube insertion device. It has a small size when inserted into the nasal cavity, improving the success rate of tube insertion, and allows for the separation of the nasojejunal feeding tube and the nasogastric tube at any time.

[0006] The main idea of ​​the technical solution adopted in this utility model is to embed the nasojejunal feeding tube into the nasogastric tube, so that there is only one tube opening when entering the nasal cavity, which improves the success rate of tube placement. At the same time, the nasojejunal feeding tube and the nasogastric tube can be separated at any time.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A nasogastric tube traction nasojejunal feeding tube placement device includes a nasojejunal feeding tube and a nasogastric tube, wherein the nasojejunal feeding tube is embedded in the nasogastric tube, characterized in that an elastic limiting ring is sleeved on the tube wall near the tail end of the nasojejunal feeding tube.

[0009] Furthermore, according to the above scheme, the cross-section of the elastic limiting ring is an isosceles triangle.

[0010] Furthermore, according to the above scheme, the elastic limiting ring with an isosceles triangle cross-section includes a first frustum and a second frustum with the same structure as the first frustum, and the first frustum and the second frustum are symmetrically arranged about the largest circular surface.

[0011] Furthermore, according to the above scheme, the cross-section of the elastic limiting ring can also be semi-circular.

[0012] The beneficial effects of this utility model are:

[0013] 1. By inserting the nasojejunal feeding tube into the feeding port of the nasogastric tube, only one tube opening is needed when passing through the anterior nasal passage, which improves the success rate of tube placement and reduces the pain of repeated tube placement for patients.

[0014] 2. The elastic limiting ring has an isosceles triangle or semicircular cross-section, which facilitates the insertion of the nasojejunal feeding tube into the feeding mouth at the end of the nasogastric tube. At the same time, the elastic limiting ring prevents the nasojejunal feeding tube from slipping out of the feeding mouth. When the nasogastric tube is moved while the nasojejunal feeding tube is fixed, the elastic limiting ring can pull out the nasojejunal feeding tube, so that the nasojejunal feeding tube and the nasogastric tube can be separated at any time.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0026] In practice, the inventors discovered that the two openings of the nasoenteric tube and the gastric tube are side by side, resulting in a large size and a low success rate of tube insertion when inserted into the nostril. The separation of the two tubes depends on the water-soluble material of the connecting tube and cannot be separated at any time as needed.

[0027] Based on the above findings, this application proposes a nasogastric tube traction nasojejunal feeding tube placement device, which reduces the size when entering the nasal cavity, improves the success rate of tube placement, and allows for the separation of the nasojejunal feeding tube and the nasogastric tube at any time. Example 1

[0028] See Figures 1-3 This application discloses a nasogastric tube traction nasojejunal feeding tube placement device, including a nasojejunal feeding tube 1 and a nasogastric tube 2. The nasojejunal feeding tube 1 is inserted into the nasogastric tube 2, so that the device has only one opening when passing through the anterior nasal passage, which improves the success rate of tube placement and reduces the pain of repeated tube placement for patients.

[0029] The nasogastric tube 2 is a standard silicone No. 16 nasogastric tube. One end of the nasogastric tube 2 has an external opening 201, and a tube cap 202 is fixedly connected to the side of the external opening 201. The other end of the nasogastric tube 2 has multiple feeding ports 203 evenly distributed (only one is shown in the figure). The feeding ports 203 prevent the nasogastric tube 2 from becoming blocked and can also be used for gastrointestinal decompression to help relieve abdominal distension and pain caused by gastrointestinal diseases (such as acute pancreatitis, intestinal obstruction, etc.). The nasogastric tube 2, the external opening 201, the tube cap 202, and the feeding ports 203 are integrated into one structure.

[0030] The nasojejunal feeding tube 1 is a Fulkai type nasojejunal feeding tube. A nasojejunal tube opening 101 is located on one side of the nasojejunal feeding tube 1. A nasojejunal tube cap 102 is fixedly connected to the side of the nasojejunal tube opening 101, which helps maintain cleanliness. The outer wall of the nasojejunal feeding tube 1 has numerical graduations (not shown in the figure) to effectively indicate the length of the product used in the body. The tube wall uses a radiodetectable material, providing imaging and positioning functions. The nasojejunal feeding tube 1, the nasojejunal tube opening 101, and the nasojejunal tube cap 102 are integrally structured. A nasojejunal tube guidewire 103 is slidably connected inside the nasojejunal feeding tube 1. One end of the nasojejunal tube guidewire 103 is connected to a nasojejunal tube cap 104. The nasojejunal tube guidewire 103 is made of metal, specifically steel wire, which helps maintain the stability of the tube when passing through the esophagus and stomach. The nasojejunal tube guidewire 103 is typically inserted to a length of approximately 25-50 cm.

[0031] It is worth noting that an elastic limiting ring 3 is fixedly fitted onto the wall of the nasojejunal feeding tube 1 0.5 cm from its tail end. The cross-section of the elastic limiting ring 3 is an isosceles triangle, including a first frustum 301 and a second frustum 302 with the same structure as the first frustum. The first frustum 301 and the second frustum 302 are symmetrically arranged about the largest circular surface. The elastic limiting ring prevents the nasojejunal feeding tube from slipping out of the feeding port. When the nasogastric tube is moved while the nasogastric tube is fixed, the elastic limiting ring can guide the nasojejunal feeding tube out, realizing the function of separating the two tubes at any time. The advantage of this device is that the nasogastric tube 2 and the nasojejunal feeding tube 1 are connected by the elastic limiting ring 3, and can be inserted into the patient's body simultaneously. Subsequently, due to the introduction and export functions of the elastic limiting ring 3, the two tubes are easily separated. Example 2

[0032] See Figure 4 Unlike Embodiment 1, the elastic limiting ring 3 has a semi-circular cross-section. Due to the unique structure of the semi-circular elastic limiting ring 3, the two tubes can be easily separated at any time, and the nasojejunal feeding tube 1 is prevented from slipping out of the feeding port 203.

[0033] One procedure for using this device is as follows: When in use, the spiral part of the nasojejunal feeding tube 1 with the elastic limiting ring 3 is inserted into the nasogastric tube 2. The nasojejunal feeding tube 1 and the nasogastric tube 2, after being combined, are simultaneously inserted into the patient's stomach through the anterior nasal passage. The two tubes are separated by rotating and pulling the nasojejunal feeding tube. The nasojejunal feeding tube 1 is fixed with one hand, and the nasogastric tube 2 is pulled out. The patient is placed in a right lateral decubitus position with the head of the bed raised 35-40cm. 200ml of air is injected into the stomach. While inserting the nasojejunal feeding tube 1, the patient can feel the peristalsis of the stomach. The tube advances 0.5cm with each inhalation of the patient. Finally, the nasojejunal feeding tube 1 is placed in the appropriate position.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
