Description

Technical Field

[0001] This utility model belongs to the field of medical consumables technology, and in particular relates to a dual-purpose gastric tube. Background Technology

[0002] A nasogastric tube is used to deliver liquid or semi-solid food into the stomach through the mouth or nose. The use of a nasogastric tube is usually performed by a doctor or nurse to ensure correct placement and avoid complications. The doctor or nurse will slowly insert the tube into the patient's mouth until it reaches the stomach. To prevent accidental removal of the nasogastric tube, some patented technologies disclose placing a balloon at the cardia of the stomach. By inflating or filling the balloon with water, it inflates to lock the tube in place at the cardia, preventing the patient from pulling it out or it from falling out.

[0003] Dysphagia, the inability of food and water to safely and smoothly pass from the mouth and pharynx into the stomach, is one of the most common complications of cerebrovascular diseases. The cricopharyngeal muscle is located proximal to the esophagus. When not eating, the cricopharyngeal muscle closes to prevent reflux into the pharynx and air from entering the esophagus. During swallowing, the cricopharyngeal muscle relaxes, allowing the food bolus to enter the esophagus. If the swallowing action is not coordinated with the relaxation of the cricopharyngeal muscle, dysphagia occurs, a condition known as cricopharyngeal achalasia. Balloon dilation is a technique used in the rehabilitation treatment of dysphagia. An appropriately sized balloon catheter is inserted through the mouth into the esophagus. At the esophageal inlet, the balloon is inflated using graded water or air injection. This intermittent traction on the cricopharyngeal muscle activates the neural network regulation in the brainstem and cerebrum, restoring swallowing function. It is mainly used for patients with cricopharyngeal muscle dysfunction caused by neurological diseases.

[0004] In clinical treatment, gastric tubes and balloon catheters are often used together, but these two devices have limited functions and cannot perform both of the above functions at the same time. Utility Model Content

[0005] In view of the above problems, the purpose of this utility model is to provide a dual-purpose gastric tube, which aims to solve the above technical problems.

[0006] The present invention adopts the following technical solution:

[0007] The dual-purpose gastric tube includes a main tube, on which a first balloon and a second balloon are disposed, wherein the distance between the two balloons matches the distance between the cardia and the cricopharyngeal muscle, and a first channel tube and a second channel tube are disposed inside the main tube, wherein the first channel tube is connected to the first balloon and the second channel tube is connected to the second balloon.

[0008] Furthermore, the main tube is divided into two sections, namely an upper section and a lower section, with the first balloon disposed in the upper section and the second balloon disposed in the lower section.

[0009] Furthermore, the upper section of the pipe is integrally connected to an upper connector at its end, and the lower section of the pipe is integrally connected to a lower connector at its top. The upper connector and the lower connector are detachably connected.

[0010] Furthermore, the upper connector includes a socket and a connecting part, wherein the socket is connected to the upper section of the pipe, the socket has a circular notch, and a middle short pipe is provided inside the circular notch, the middle short pipe extending out of the connecting part; the lower connector includes a sleeve and an inner opening, the inner opening is connected to the lower section of the pipe, the sleeve is connected and fixed to the connecting part, and the inner opening also has a clearance hole to avoid the middle short pipe.

[0011] Furthermore, the connecting part has flat openings at the top and bottom, with locking blocks on the flat openings, and the sleeve part has a locking groove. After the connecting part is inserted into the sleeve part, the locking blocks are engaged in the locking groove.

[0012] The beneficial effects of this utility model are: the gastric tube of this utility model has two functions. On the basis of the conventional gastric tube function, a first balloon is set at a certain height away from the second balloon of the gastric tube. When the gastric tube is used normally, the first balloon is not inflated, and only the second balloon is inflated. When it can continue to be used as a catheter balloon, the first balloon can be inflated and deflated intermittently to achieve intermittent traction of the cricopharyngeal muscle and complete the synchronous treatment of swallowing dysfunction.

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0017] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0018] like Figure 1-3As shown, the dual-purpose gastric tube provided in this embodiment includes a main tube, on which a first balloon 3 and a second balloon 4 are provided. The distance between the two balloons matches the distance between the cardia and the cricopharyngeal muscle. A first channel tube 5 and a second channel tube 6 are provided inside the main tube, wherein the first channel tube 5 is connected to the first balloon 3 and the second channel tube 6 is connected to the second balloon 4.

[0019] In most adults, the cardia is located approximately 24 cm below the cricopharyngeal muscle. A standard gastric tube is a single catheter with an operating connector at the top. Some patented technologies also include a balloon around the lower part of the tube, which, when inflated, is used to secure it to the cardia and prevent accidental removal. Therefore, the inner wall of the gastric tube also contains a channel tube that connects to the balloon.

[0020] In the first structural design of this invention, a first channel tube is added to the inner wall of the gastric tube. A first balloon is placed at a certain distance above the first channel tube, and the first channel tube is connected to the first balloon. Therefore, when the catheter balloon is applied, the first balloon can be intermittently inflated and deflated to achieve intermittent traction on the cricopharyngeal muscle and complete the simultaneous treatment of swallowing dysfunction.

[0021] In the second structural design, although the distance between the cardia and cricopharyngeal muscle is approximately 24 cm, this distance may not be accurate for patients of different body types and heights. A significant deviation could result in a large discrepancy between the first balloon and the cricopharyngeal muscle, hindering the treatment effect. In this design, the main tube is divided into upper and lower sections, namely upper tube 1 and lower tube 2. The first balloon 3 is located in the upper tube 1, and the second balloon 4 is located in the lower tube 2. An upper connector 7 is integrally connected to the end of the upper tube 1, and a lower connector 8 is integrally connected to the top of the lower tube 2. The upper connector 7 and lower connector 8 are detachably connected. A second channel tube is provided in both the upper and lower tubes, and two connectors connect these two parts without affecting the inflation of the second balloon.

[0022] As a specific structure, the upper connector 7 includes a socket portion 71 and a connecting portion 72, wherein the socket portion 71 is connected to the upper section pipe 1, the socket portion 71 has a circular notch 73, and a middle short pipe 74 is provided in the circular notch 73, the middle short pipe 74 extends out of the connecting portion 72; the lower connector 8 includes a sleeve portion 81 and an inner opening portion 82, the inner opening portion 82 is connected to the lower section pipe 2, the sleeve portion 81 is connected and fixed to the connecting portion 72, and the inner opening portion 82 also has a clearance hole 83 to avoid the middle short pipe.

[0023] The two connectors are integrally connected to the two pipe sections using a heat fusion method, preventing them from detaching. One end of the middle short pipe of the upper connector is inserted into the second channel pipe inside the upper pipe section, and the other end is inserted into the second channel pipe inside the lower pipe section, ensuring no air leakage. The clearance hole at the inner opening of the lower connector also allows for clearance of the second channel pipe. The upper and lower connectors are directly connected. In the illustration, the connecting part 72 has flat openings 75 at the top and bottom, with locking blocks 76 on the flat openings 75. The pipe sleeve part 81 has a locking groove 84. After the connecting part is inserted into the pipe sleeve part, the locking blocks 76 engage with the locking grooves 84, ensuring that the two connectors will not detach completely.

[0024] This structural design allows for the selection of a lower segment of the catheter of appropriate length for different patients, broadening its application range. Furthermore, the upper segment can also be used directly as a balloon catheter, further enhancing its adaptability.

[0025] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
