Description

Technical Field

[0001] The utility model relates to the technical field of nasointestinal tube connectors, in particular to an integrated anti-backflow nasointestinal tube connector. Background Art

[0002] Nasoenteric tubes are used to provide water and food to patients who cannot swallow independently, to maintain metabolism, weight and nutrition. One end of the nasoenteric tube is placed into the gastrointestinal tract through the esophagus, and water and food are injected through a syringe or other device connected to the connector of the nasoenteric tube.

[0003] The existing nasogastric tube connector seals and protects the injection end of the nasogastric tube, and is opened to connect the tube during injection. The user is required to fold the tube back and inject nutrient solution at the same time to avoid air inflow into the active mouth or gastrointestinal reflux, and the operation requires both hands, which is inconvenient.

[0004] In the actual operation process, the nutrient solution usually needs to be injected in batches with a certain amount. The user needs to pay attention to the angle of the pipe during repeated injections and intervals to avoid backflow. In addition, it is difficult for family members to maintain the folded state during the intervals between nutrient solution injections, which makes it easy to make operating errors and it is not easy to free both hands. The family members have high operating requirements and maintaining the folded state for a long time can easily cause fatigue. Utility Model Content

[0005] The utility model aims to provide an integrated anti-reflux nasointestinal tube connector to solve the technical problem in the prior art that air easily flows into the active interface of the nasointestinal tube, causing gastrointestinal reflux.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1 As shown, the utility model provides an integrated anti-backflow nasointestinal tube connector, including a two-way connector 10 with a storage bin 11, a spring sheet group 20 is movably installed on the two-way connector 10 near the storage bin 11, the spring sheet group 20 elastically rotates and closes around the connection with the storage bin 11 to form a group partition structure, and a sealing cover 30 is movably provided on the two-way connector 10 near the feed end, and the sealing cover 30 is threadedly connected to the two-way connector 10 and movably abuts against the spring sheet group 20 to form a double closed structure.

[0023] The utility model adopts an active connection to form an integrated anti-backflow structure, and achieves the purpose of segmented separation through the double closure of the spring sheet and the sealing cover. The elastic closure at both ends is conducive to timely closure after the injection is completed. When in use, the two ends are further connected to achieve mutual penetration. After the injection, it automatically closes to prevent backflow, which can minimize the gastrointestinal reflux caused by improper operation of the user and has low operation requirements for the user.

[0024] The sealing effect on the two-way joint 10 is increased by the spring sheet group 20. When the push-in end is connected, the spring sheet group 20 is driven to open to form a through state for push-in, and when the push-in end is taken out, it automatically closes to form a closed state, which is beneficial to prevent backflow and free the operator's hands from being in a folded state, which is beneficial to reduce operator fatigue.

[0025] like Figure 1 and Figure 2 As shown, the longitudinal section of the storage bin 11 is a trapezoidal structure, and the diameter of the storage bin 11 is larger than the diameter of the port of the bidirectional connector 10 .

[0026] The storage bin 11 reserves space for the folding of the shrapnel group 20, so that when the nasogastric tube and the injection tube push the shrapnel group 20 to open, they can be connected to the middle of the two-way connector 10 to complete the connection, thereby injecting the nutrient solution into the nasogastric tube through the injection tube.

[0027] like Figure 1 and Figure 2As shown, the spring sheet group 20 is symmetrically arranged in two groups with respect to the vertical center line of the bidirectional joint 10. Each group of the spring sheet group 20 is symmetrically composed of two semicircular spring sheets 21 and matches the bidirectional joint 10 to form a circular structure. The straight edges of the two spring sheets 21 are movably abutted to form a closed structure.

[0028] By providing the spring sheet group 20 at both ends of the bidirectional joint 10, a double insurance effect can be achieved. When the nasogastric tube end is connected, the connection depth can be adjusted according to the use requirements. When there is no need to push the nutrient solution temporarily, the nasogastric tube is connected to one side of the spring sheet group 20, which is conducive to enhancing the sealing effect.

[0029] When the nutrient solution is injected, the nasogastric tube is pushed further in to drive the spring piece to open and complete the deep insertion. At this time, the output end of the two-way connector 10 is in a fully open state.

[0030] The output access state and the input access state of the bidirectional connector 10 are controlled in sections. When injection is required, the syringe needs to push the spring 21 to deeply insert and complete the connection with the nasogastric tube, and then the nutrient solution can be injected.

[0031] During the interval between push injections, the shrapnel 21 rebounds and closes when the syringe is pulled out, and no other operation is required. When the next push injection is connected, it is opened to complete the push injection of the nutrient solution. This can avoid the backflow caused by the operator's careless operation errors as much as possible, play a double insurance role, and facilitate family members to complete the operation.

[0032] like Figure 1 and Figure 2 As shown, the combined diameter of the two groups of spring plates 20 is smaller than the length of the storage bin 11 , and the two ends of the two groups of spring plates 21 are respectively movably abutted against the nasogastric tube and the feeding tube and folded into the storage bin 11 to form an interconnected structure.

[0033] The nasogastric tube and the feeding tube are connected to push the spring group 20 to open, so that the two groups of spring groups 20 are completely folded into the storage bin 11, and one end of the nasogastric tube and one end of the feeding tube are deeply connected in the middle of the storage bin 11. At this time, the two-way joint 10 is fully opened to push the nutrient solution, which is conducive to achieving the purpose of two-way closure and enhancing the closure effect and anti-backflow effect of the two-way joint 10.

[0034] like Figure 1 and Figure 3 As shown, the inner wall of the sealing cover 30 is provided with a plug 31 matching the port of the two-way joint 10, the diameter of the plug 31 is smaller than the diameter of the shrapnel group 20, and the length of the plug 31 is smaller than the distance from the shrapnel group 20 to the port of the two-way joint 10.

[0035] The sealing cover 30 is connected to the two-way joint 10 by rotating, and the plug 31 is driven to seal and fix the injection end of the two-way joint 10. When the plug 31 is sealed, there is a certain distance between it and the spring group 20, so that the plug 31 will not cause the spring group 20 to open. A double-closed structure is formed by the plug 31 and the spring group 20, and the backflow prevention effect is achieved when the plug 31 is opened alone.

[0036] The above embodiments are only exemplary embodiments of the present application and are not intended to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art may make various modifications or equivalent substitutions to the present application within the essence and protection scope of the present application, and such modifications or equivalent substitutions shall also be deemed to fall within the protection scope of the present application.
