Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a fixing piece for the end of a nasogastric tube. Background Art

[0002] Most of the existing connections between syringes for injecting nutrient solutions or nutritional fluids and food nasogastric tubes adopt an interference fit connection method to make the two closely connected and avoid disengagement and liquid leakage during the injection process. However, this tight connection method also causes another problem, that is, during the disengagement process of the two, manual pulling is required, which easily causes violent shaking during the insertion and removal of the cap of the gastrointestinal tube adapter, and the tube located in the nasogastric part slides, making the use of the nasogastric tube unsafe.

[0003] At the same time, during the actual use of the nasogastric tube, usually the tube between the nasogastric tube adapter and the nose is too long, which is prone to pulling or under the action of the gravity of the tube itself, the nasogastric tube body located in the esophagus is pulled, causing the position of the tube body to change. And the existing nasogastric tube needs to be fixed on the human skin through adhesives such as adhesive tapes. After a long time of sticking, skin problems are likely to occur. Content of the Utility Model

[0004] The purpose of the utility model is to provide a fixing piece for the end of a nasogastric tube to solve the technical problems in the prior art that, due to the excessive length of the part of the nasogastric tube exposed outside the body, it is easy to cause pulling, resulting in the change of the position of the nasogastric tube and causing repeated intubation, and it can avoid using adhesives such as adhesive tapes to stick and fix the nasogastric tube body on the human skin.

[0005] To solve the above technical problems, the utility model specifically provides the following technical solutions:

[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 and Figure 2 As shown, the utility model provides a nasogastric feeding tube end fixing part, including a bending frame 1 and a joint cover 2, both ends of the bending frame 1 are connected with joints 3, a pipe connection seat 4 is connected to the bending frame 1 between the two joints 3, and the pipe connection seat 4 is connected to the two joints 3;

[0023] A nose pad 5 is provided at both ends of the bending frame 1 near the bottom of the joint 3. The two nose pads 5 are mirror-symmetrical and perpendicular to the plane where the bending frame 1 is located. The two nose pads 5 are used to fit on both sides of the nose respectively.

[0024] The joint cover 2 is connected to the bending frame 1 through an outwardly convex arc-shaped member 7. A cylindrical slot 6 is provided on the joint cover 2, and the cylindrical slot 6 is used for matching and connecting with the nasogastric feeding tube body.

[0025] When this embodiment is used, the bending frame 1 is placed on the bridge of the nose, the two nose support members 5 naturally fit and clamp the sides of the nose, the tube body of the nasogastric feeding tube connected to the connecting pipe seat 4 is inserted from the nose end, and the connecting pipe seat 4 and the cavities inside the two joints 3 are smoothly transitioned.

[0026] Considering the support, with the plane where the bending frame 1 and the two joints 3 are located as a reference, there is an angle between the connection between the tube holder 4 and the bending frame 1, and the tube body of the nasogastric tube connected to the tube holder 4 is inserted into the nasal cavity so that it naturally bends upward, but the tube body of the nasogastric tube does not fold.

[0027] That is, the nasogastric tube end fixing member in this embodiment is combined with the nose bridge of the human body, so that the tube body of the nasogastric tube is exposed to the outside of the human body only from the bending frame 1 to the pen tip, thereby reducing the problem of excessive exposure of the tube body of the nasogastric tube to the outside of the human body. At the same time, the nose bridge is used to form two joints 3 and the support point of the bending frame 1, which can avoid skin problems caused by excessive adhesion of the skin with adhesive tape.

[0028] At the same time, the tube body from the tube socket 4 to the nose tip is in an outwardly convex curved shape, and its structure can transfer force to the bending frame 1 when subjected to force, and the part located in the nose where the nostrils are inserted plays a supporting role and applies force to the tube body.

[0029] At the same time, in the present embodiment, the structure of the nose pad 5 utilizes the bionic shape of the side of the human nose to make the nose pad 5 fit the side of the nose more closely. Of course, it can have a certain initial clamping force under the structural limitation of the bending frame 1, that is, the distance between the two nose pads 5 is smaller than the average distance between the two sides of the bridge of the nose. Therefore, when the bending frame 1 is placed on the bridge of the nose, the two nose pads 5 can fit the side of the nose.

[0030] Furthermore, the outwardly convex arc-shaped member 7 in the present embodiment specifically adopts the structure of a cylindrical memory metal strip coated with PET material, and its purpose is to provide a supporting force to the bending frame 1, which has the same effect on the outwardly convex curved shape of the tube body from the connecting seat 4 to the nose tip part mentioned above.

[0031] During specific use, the tube body of the nostril insertion part can be inserted into the cylindrical slot 6, so that the joint cover 2 is equivalent to a nasal plug structure inserted into the nostril to support the nostril, and the convex arc-shaped part 7 obtains the supporting force of the supporting bending frame 1.

[0032] At the same time, it can also prevent the tube inserted into the nasal cavity from being pulled.

[0033] The nasogastric feeding in this embodiment can avoid the use of gluing to fix the nasogastric feeding tube on a part of the human body, thereby avoiding the contact between auxiliary materials or tape and the skin, and can reduce the length of the tube body exposed to the outside of the nasogastric feeding tube, thereby avoiding the shaking of the nasogastric feeding tube body causing the position of the nasogastric feeding tube in the human body to change, resulting in secondary intubation.

[0034] In order to more clearly illustrate the function of the above-mentioned joint cover 2, this embodiment provides an embodiment of the joint cover 2, including a cylindrical member 21 and a conical member 22 connected to one end of the cylindrical member 21, a cylindrical groove 6 is arranged on the side wall of the cylindrical member 21, and the cylindrical groove 6 extends to the conical member 22 along the axial direction of the cylindrical member 21, and an open mouth 23 is formed on the surface of the cylindrical member 21, and the tube body of the nasogastric feeding tube enters the cylindrical groove 6 on the cylindrical member 21 from the connecting pipe seat 4, and enters the nasal cavity after passing through the square buckle 23.

[0035] Of course, when the connector cover 2 is not used as a nasal support structure, it is inserted into the opening of the connector 2 to close the connector cover 2.

[0036] The conical member 22 cooperates with the end opening of the joint 3 , and when the conical member 22 enters the end opening of the joint 3 , the open mouth 23 is squeezed and closed.

[0037] One end of the outwardly convex arc-shaped member 7 is connected to the connection between the joint 3 and the bending frame 1 , and the other end is connected to the columnar member 21 .

[0038] In this embodiment, a plurality of through holes 8 are uniformly arranged on the nose pad member 5. The through holes 8 communicate with the two side surfaces of the nose pad member 5. The opening diameter of the through hole 8 on the inner surface is larger than that on the outer surface. The purpose is that when the nose pad member 5 contacts the side skin of the nose, due to the acting force exerted on the side of the nose by its structure, part of the nose skin can enter the through hole 8, and then a contact effect between the nose pad member 5 and the side of the nose can be generated based on this, avoiding the slippage of the nose pad member 5.

[0039] The above embodiments are only exemplary embodiments of the present application and are not used to limit the present application. The protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements within the essence and protection scope of the present application, and such modifications or equivalent replacements should also be regarded as falling within the protection scope of the present application.
