Description

Technical Field

[0001] The utility model relates to the medical field, in particular to a multi-purpose three-way gastric tube. Background Art

[0002] In the existing medical environment, some patients are unable to eat independently due to external force or their own illness. In order to ensure that the patients can maintain the nutrition they need during treatment, people usually use gastric tubes to deliver nutrient solution to the patients. When fluid or gas accumulates in the patient's stomach, it can also be sucked out through the gastric tube. However, the existing gastric tubes usually have only one interface. In order to complete operations such as feeding or extracting accumulated fluid, the gastric tube needs to be constantly folded in half to ensure that the gastric tube will not be infected by external bacteria. Therefore, in order to ensure the sterile environment of the gastric tube while performing operations such as feeding or extracting the gastric tube, people usually connect a multi-purpose three-way valve to the interface of the gastric tube to achieve the effect of a multi-purpose three-way gastric tube.

[0003] Existing multi-purpose three-way gastric tubes are usually connected to a three-way pipe at the inlet end of the gastric tube. The operating pipe to be used is selected by adjusting the direction of the valve of the three-way pipe, and the pipe at the other end is closed. After feeding or extraction is completed, the valve is closed to ensure a sterile environment inside the gastric tube.

[0004] Although this multi-purpose three-way gastric tube can perform multiple operations on the gastric tube while ensuring that the internal environment of the gastric tube is sterile, once the gastric tube is blocked by food or fluid lumps during feeding or extracting accumulated fluid, due to its generally T-shaped right-angle structure, it is difficult for the clearing device for clearing the gastric tube to enter the gastric tube at a right angle from the entrance of the three-way pipe, thereby causing gastric tube blockage. Utility Model Content

[0005] The technical problem to be solved by the utility model is that when the existing multi-purpose three-way gastric tube is blocked, it is difficult to clear it due to its T-shaped structure.

[0006] In order to solve the above technical problems, the technical solution provided by the utility model is: a multi-purpose three-way gastric tube, including a gastric tube, a three-way pipe is provided on one side of the gastric tube, the three-way pipe is connected to the gastric tube by hot melt adhesive, the number of the three-way pipes is 2, the pipe openings of the two three-way pipes are connected by hot melt adhesive, and the two three-way pipes form a spliced ​​pipe, the pipe openings of the spliced ​​pipe include dredging ports and gastric tube interfaces at both ends of the main pipe, and a feeding port and a gastric acid suction port located at the branch pipe end of the spliced ​​pipe.

[0007] As an improvement, the three-way pipe includes an upper half pipe, a lower half pipe and a check valve ball located between the upper half pipe and the lower half pipe. A rotating rod for rotating the check valve ball is provided on one side of the check valve ball. The straight rod side of the rotating rod passes through the upper half pipe and the check valve ball. The interior of the check valve ball is provided with a T-shaped opening that is the same as the pipe opening of the three-way pipe.

[0008] As an improvement, the upper half of the pipe is sealed and connected to the lower half of the pipe by hot melt adhesive, and the rotating rod is connected to the on-off valve ball by body contact.

[0009] As an improvement, the rotating rod is connected to the upper half of the pipe via a sealing ring, and the sealing ring passes through the upper half of the pipe.

[0010] As an improvement, the gastric tube is connected to the gastric tube interface of the three-way pipe through hot melt glue.

[0011] As an improvement, the dredging port, the feeding port and the gastric acid suction port of the spliced ​​pipe are all provided with rubber plugs for sealing.

[0012] The advantages of the present invention over the prior art are that the multifunctional three-way pipe of the present device is a spliced ​​pipe composed of two three-way pipes, a dredging port is provided at the pipe openings at the opposite ends of the gastric tube interface, while the feeding port and the gastric acid suction port are still in a perpendicular state to the gastric tube interface, and the use of the port is adjusted by a check valve ball. When the gastric tube is blocked, the two check valve balls are rotated. When the check valve balls between the gastric tube interface and the dredging port are both in the open state, medical staff can use the dredging device to dredge the pipe, avoiding the problem of dredging difficulty caused by the right-angle structure of the traditional three-way pipe.

[0018] The present invention will be described in further detail below with reference to the accompanying drawings.

[0019] As the instruction manual Figure 1 、 3 As shown in Figure 4, it includes a gastric tube 1, and a three-way pipe 2 is provided on one side of the gastric tube 1. The three-way pipe 2 includes an upper pipe 21, a lower pipe 22 and a check valve ball 23 located between the upper pipe 21 and the lower pipe 22. The upper pipe 21 is sealed with the lower pipe 22 by hot melt adhesive. Since the upper pipe 21 and the lower pipe 22 are sealed with hot melt adhesive, the position of the check valve ball 23 is easier to determine and fix it to avoid the situation where the through hole of the check valve ball 23 opened in the upper pipe 21 is not sealed tightly when the check valve ball 23 is placed.

[0020] A rotating rod 231 for rotating the check valve ball 23 is provided on one side of the check valve ball 23. The straight rod side of the rotating rod 231 passes through the upper pipe 21 and the check valve ball 23. The interior of the check valve ball 23 is provided with a T-shaped opening 232 which is the same as the pipe opening of the three-way pipe 2. The rotating rod 231 is connected to the check valve ball 23 through body contact. The rotating rod 231 is connected to the upper pipe 21 through a sealing ring 4. The sealing ring 4 passes through the upper pipe 21. The sealing of the sealing ring 4 avoids the existence of a gap between the upper pipe 21 and the rotating rod 231.

[0021] The three-way pipe 2 is connected to the gastric tube 1 by hot melt adhesive. By injecting the hot melt adhesive, there is no gap at the interface between the gastric tube 1 and the three-way pipe 2, thereby ensuring its sealing.

[0022] As the instruction manual Figure 1 、 2 As shown, the number of the three-way pipes 2 is two, and the pipe openings of the two three-way pipes 2 are connected by hot melt adhesive. The two three-way pipes 2 form a spliced ​​pipe 3 to ensure the sealing of the connection end of the spliced ​​pipe 3. The pipe openings of the spliced ​​pipe 3 include the dredging port 31 and the gastric tube interface 32 at both ends of the main pipe, as well as the feeding port 33 and the gastric acid suction port 34 located at the branch pipe end of the spliced ​​pipe 3. The dredging port 31, the feeding port 33 and the gastric acid suction port 34 of the spliced ​​pipe 3 are all provided with a rubber plug 5 for sealing. The rubber plug 5 avoids the purity of the inside of the spliced ​​pipe 3 when not in use.

[0023] During the specific implementation of the present invention, (the three-way pipe 2 is made of transparent plastic material), a sealing ring 4 is placed in the sealing ring 4 groove inside the shell of the upper half pipe 21, and the check valve ball 23 is placed inside the curved surface of the shell of the upper half pipe 21. The connecting groove of the rotating rod 231 of the check valve ball 23 is aligned with the through hole of the sealing ring 4. The straight rod end of the rotating rod 231 passes through the sealing ring 4 and is inserted into the connecting groove of the rotating rod 231 inside the check valve ball 23. The lower half pipe 22 is aligned with the upper half pipe 21 and sealed with hot melt adhesive. The connecting ends of the two three-way pipes 2 are aligned and the two are sealed with hot melt adhesive. The interface end of the gastric tube 1 is put on the gastric tube interface 32 end of the splicing pipe 3 and the two are sealed with hot melt adhesive.

[0024] During use, one end of the gastric tube 1 is inserted into the stomach from the patient's nostril. When sucking out the accumulated fluid, the check valve ball 23 is rotated to connect the T-shaped opening 232 to the gastric acid suction outlet 34 and the gastric tube interface 32. The rubber stopper 5 is removed and the accumulated fluid suction device is connected to the gastric acid suction outlet 34 for operation. After the extraction is completed, the pipeline is cleaned with clean water and the gastric acid suction outlet 34 is closed with the rubber stopper 5. The operating principle of the feeding port 33 is the same as that of the gastric acid suction outlet 34. When the gastric tube 1 is blocked during eating or sucking, the check valve ball 23 is rotated to form a straight path between the gastric tube interface 32 and the dredging port 31 to facilitate the cleaning of the dredging device.

[0025] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
