Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically, to disposable nasogastric tubes. Background Technology

[0002] In clinical medical practice, disposable nasogastric tubes are widely used as important medical devices in key aspects such as the treatment of gastrointestinal diseases, gastrointestinal decompression, and enteral nutritional support. They safely and effectively enter the gastrointestinal tract through the nasal cavity, not only effectively draining accumulated gas, fluids, and food residue, relieving abdominal distension, and optimizing gastrointestinal function, but also providing essential nutritional support for patients unable to eat orally. This has immeasurable value in improving patients' quality of life and treatment outcomes.

[0003] However, in practice, existing disposable nasogastric tube technology still faces several challenges, urgently requiring technological innovation and optimization. The primary issue lies in the precision control of the insertion process. To improve the success rate of intubation, traditional methods involve pre-positioning a visual fiber guidewire inside the nasogastric tube to assist in positioning. While this method enhances the intuitiveness of the procedure to some extent, once the guidewire enters the stomach, stomach contents (such as food residue and gastric juice) often obstruct the view of the visual guidewire, leading to positioning difficulties and even misleading the insertion direction, increasing the risk of intubation failure and patient discomfort.

[0004] Secondly, the comfort level during intubation is also a significant concern. Nasogastric tubes require considerable force to overcome physiological curvature, which can easily lead to scraping of the nasal mucosa or the inner wall of the gastrointestinal tract, causing pain and discomfort, and potentially even tissue damage, affecting subsequent treatment and the patient's recovery process.

[0005] Given the aforementioned technical bottlenecks, it is particularly urgent to develop a disposable nasogastric tube that can ensure rapid and accurate intubation while minimizing patient discomfort. Utility Model Content

[0006] In view of the problems existing in the prior art, this utility model provides a disposable nasogastric tube to solve the technical problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a disposable nasogastric tube, comprising a flexible tube and a connecting end, wherein one end of the flexible tube has an arc-shaped edge, and the other end is sleeved outside the connecting end. The connecting end includes a connecting tube for connecting to the flexible tube, a main port for feeding or drainage, and a flushing port for air or water flushing. Both the main port and the flushing port are connected to the flexible tube through the connecting tube.

[0008] The present invention is further configured to include a first cap, the first cap including a first main body portion and a first sealing plug for inserting into the main port and sealing the main port.

[0009] The present invention is further configured to include a second cap, the second cap comprising a second main body portion and a second sealing plug for inserting into the flushing port and sealing the flushing port.

[0010] The present invention is further provided that a first anti-loss rope is fixedly provided between the connecting tube and the first cap.

[0011] The present invention is further provided that a second anti-loss rope is fixedly provided between the rinsing port and the second cap.

[0012] The present invention is further configured such that the first sealing plug and the second sealing plug are both hollow frustum-shaped structures, and the diameter of the first sealing plug near the first cap is greater than the diameter of the other end of the first sealing plug, and the diameter of the second sealing plug near the second cap is greater than the diameter of the other end of the second sealing plug.

[0013] The present invention is further configured such that the first cap and the second cap are respectively provided with a first extension piece and a second extension piece.

[0014] The present invention is further configured to include a clamp, which is installed on the outside of the hose sleeved on the connecting end, for fastening the connection between the hose and the connecting end.

[0015] Compared with the prior art, the present invention provides a disposable nasogastric tube, which has the following beneficial effects:

[0016] 1. This utility model has a rounded edge fixed at one end of the flexible tube to improve the smoothness of the tube end face, so as to avoid damage to the nasal cavity or gastrointestinal wall of the patient during insertion and reduce the patient's discomfort and pain.

[0017] 2. When this utility model is used with a visual fiber guidewire for insertion, gas or water can be introduced into the flushing port to clear the obstruction in the direction of the visual fiber guidewire's advance, so as to prevent contents (such as food residue, gastric juice, etc.) from affecting the visual fiber guidewire's field of vision, thereby improving the accuracy of cannulation.

Example

[0025] Please see Figure 1-3 A disposable nasogastric tube includes a flexible tube 1 and a connecting end 2. One end of the flexible tube 1 has an arc-shaped edge 101, and the other end is sleeved on the connecting end 2. The connecting end 2 includes a connecting tube 201 for connecting with the flexible tube 1, a main port 202 for feeding or drainage, and a flushing port 203 for air flushing or water flushing. The main port 202 and the flushing port 203 are both connected to the flexible tube 1 through the connecting tube 201.

[0026] During insertion, the visual fiber guidewire is first pre-placed inside the flexible tube 1 through the main port 202. The flexible tube 1 is then inserted into the patient's nasal cavity. The rounded edge 101 reduces discomfort and pain when the flexible tube 1 contacts the patient's nasal cavity. The position of the flexible tube 1 port is determined by the visual fiber guidewire. When the visual fiber guidewire's view is obstructed by contents (such as food residue, gastric juice, etc.), water or air can be introduced through the flushing port 203 to remove obstructions and improve insertion accuracy. Once the flexible tube 1 is in place, the visual fiber guidewire is pulled out from the main port 202. In actual use, the main port 202 can be connected to external equipment to introduce nutrient solution into the flexible tube 1 through the main port 202 to ensure the patient's nutritional needs, or to drain accumulated gas, liquid, and food residue from the gastrointestinal tract to relieve the patient's abdominal distension symptoms. Example

[0027] The disposable nasogastric tube also includes a first cap 3 and a second cap 4. The first cap 3 includes a first main body 301 and a first sealing plug 302 for inserting into the main port 202 and sealing the main port 202. The second cap 4 includes a second main body 401 and a second sealing plug 402 for inserting into the flushing port 203 and sealing the flushing port 203. A first anti-loss rope 5 is fixedly provided between the connecting tube 201 and the first cap 3. A second anti-loss rope 6 is fixedly provided between the flushing port 203 and the second cap 4. The first sealing plug 302 and the second sealing plug 402 are both hollow frustum-shaped structures. The diameter of the first sealing plug 302 near the first cap 3 is larger than the diameter of the other end of the first sealing plug 302, and the diameter of the second sealing plug 402 near the second cap 4 is larger than the diameter of the other end of the second sealing plug 402. The first cap 3 and the second cap 4 are respectively provided with a first extension piece 303 and a second extension piece 403.

[0028] After the visible fiber guidewire is pulled out, there is no need to use the flushing port 203 anymore. The second sealing plug 402 of the second cap 4 can be inserted into the flushing port 203 to seal it and prevent external dust and impurities from entering the hose 1 from the flushing port 203. Moreover, when the main port 202 is not connected to external equipment for nutrient delivery or drainage, the first sealing plug 302 on the first cap 3 can also be inserted into the main port 202 to seal it. Example

[0029] The disposable nasogastric tube also includes a clamp 7, which is installed on the outside of the flexible tube 1 fitted on the connecting end 2, and is used to fasten the connection between the flexible tube 1 and the connecting end 2.

[0030] The hose 1 is fitted over the connecting end 2 and secured with clamp 7.
