[0038] like Figures 1 to 5As shown, according to an embodiment of the present invention, a fixing device 100 for a nasofeeding tube 200 is proposed, which includes a main body 10, a clamping member 20 and a retaining structure 30. The main body 10 is used to be arranged in the patient's nostrils, and the main body 10 includes a penetration channel 12 for the nasofeeding tube 200 to pass through. The clamping member 20 includes a first part 21 and a second part 22 connected to each other. The second part 22 is connected to the main body 10 and is used to abut against the inner surface of the patient's nostrils. The first part 21 is used to abut against the outer surface of the patient's nose. The retaining structure 30 is arranged in the penetration channel 12. The retaining structure 30 cooperates with the main body 10 and the nasofeeding tube 200 respectively to limit the relative displacement of the nasofeeding tube 200 and the main body 10.
[0039] It should be understood that when the fixing device 100 is in use, the first part 21 and the second part 22 respectively rest against the outer surface of the patient's nose and the inner surface of the nostril, that is, the first part 21 and the second part 22 form a clamping structure, which is clamped at the position of the patient's nose, thereby fixing the main body 10 with the nasogastric tube 200, and then using the main body 10 to fix the nasogastric tube 200.
[0040] In addition, when the nasogastric tube 200 is inserted into the insertion channel 12 of the main body 10, external force can drive the nasogastric tube 200 to overcome the resistance generated by the retaining structure 30 to the nasogastric tube 200. When the external force is released, the retaining structure 30 generates resistance (such as friction, etc.) to the nasogastric tube, thereby maintaining the position of the nasogastric tube 200 and further fixing the nasogastric tube 200.
[0041] According to the fixing device 100 for a nasogastric tube 200 of the present application, when fixing the nasogastric tube 200, the nasogastric tube 200 is inserted into the insertion channel 12, one end of the nasogastric tube 200 is inserted through the patient's nostril, and the other end is retained outside the patient's body. The main body 10 is placed in the patient's nostril, and the first portion 21 and the second portion 22 respectively abut against the outer surface of the patient's nose and the inner surface of the nostril, thereby fixing the fixing device 100 to the patient's nose. The nasogastric tube 200 and the main body 10 are relatively fixed by the retaining structure 30, thereby achieving the fixation of the nasogastric tube 200. When fixing the nasogastric tube 200, the fixing device 100 reduces the use of medical tape, thereby improving the fixing strength of the nasogastric tube 200 and reducing the discomfort caused by the medical tape to the patient, thereby improving the patient's comfort.
[0042] In some embodiments of the present invention, Figures 3 to 5As shown, there are multiple retaining structures 30, and the multiple retaining structures 30 are arranged around the nasogastric tube 200. By providing multiple retaining structures 30, the matching positions between the main body 10 and the nasogastric tube 200 can be increased, thereby increasing the fixing strength of the nasogastric tube 200, so that the stability of the nasogastric tube 200 is effectively improved.
[0043] It should be understood that the plurality of retaining structures 30 may be arranged at equal intervals or at unequal intervals around the circumference of the nasogastric tube 200 .
[0044] It should be noted that the number of the retaining structures 30 can be two, three, four, five, six, seven, eight, etc.
[0045] In some embodiments of the present invention, Figures 3 to 5 As shown, the retaining structure 30 includes an elastic arm 31 , one end of which is connected to the inner wall of the penetration channel 12 , and the elastic arm 31 rests on the outer surface of the nasogastric tube 200 in an elastically deformed state.
[0046] Specifically, one end of the elastic arm 31 is connected to the inner wall of the passage 12 of the main body 10. In the absence of external force, the elastic arm 31 extends radially along the passage 12. When the nasogastric tube 200 is inserted into the passage 12, the tube 200 causes the elastic arm 31 to elastically deform, and the deformed elastic arm 31 rests against the outer surface of the tube 200. After the position of the tube 200 is adjusted, the external force driving the tube 200 is released, and the deformed elastic arm 31 rests against the tube 200, applying positive pressure to the tube 200, thereby maintaining the position of the tube 200.
[0047] The elastic arm 31 has a simple structure, which can effectively reduce the manufacturing cost of the fixing device 100. At the same time, the elastic arm 31 has a better effect of maintaining the position of the nasogastric tube 200.
[0048] In some embodiments of the present invention, Figures 3 to 5 As shown, the retaining structure 30 further includes a first elastic protrusion 32 , which is provided on the elastic arm 31 and abuts against the nasogastric tube 200 .
[0049] Specifically, by providing the first elastic protrusion 32 on the elastic arm 31, the friction force on the nasofeeding tube 200 can be increased, thereby further improving the position holding strength of the nasofeeding tube 200, so that the stability of the nasofeeding tube 200 can be further improved.
[0050] In some embodiments of the present invention, there are multiple first elastic protrusions 32, and the multiple first elastic protrusions 32 are dispersedly arranged on the elastic arm 31. By providing multiple first protrusions, the friction force on the nasogastric tube 200 is further increased, thereby further improving the position retention strength of the nasogastric tube 200, so that the stability of the nasogastric tube 200 can be further improved.
[0051] It should be understood that the plurality of first elastic protrusions 32 may be evenly distributed on the elastic arm 31 or unevenly distributed.
[0052] In the present application, the retaining structure 30 can be an integral structure with the main body 10, or a split structure. When the retaining structure 30 and the main body are an integral structure, they can be processed by one-piece molding. When the retaining structure 30 and the main body are split structures, the two are independently processed and then connected and fixed by welding or bonding.
[0053] In some embodiments of the present invention, the retaining structure 30 and the main body 10 are integrated into one structure. By providing the retaining structure 30 and the main body 10 as an integrated structure, the processing steps can be shortened, so that the processing efficiency can be improved.
[0054] In some embodiments of the present invention, the retaining structure 30 is a silicone member. The retaining structure 30 and the main body 10 are both configured as silicone members, and the two are integrally formed. The silicone member has good skin affinity, can reduce harm to the patient, and can further improve the patient's comfort during use.
[0055] In addition, if Figures 2 to 5 As shown, at least one elastic convex ring 11 is provided on the outer peripheral surface of the main body. By providing the elastic convex ring 11, the stability of the fixation of the main body 10 to the patient's nostrils can be increased, and the fixing effect of the nasogastric tube 200 is further improved.
[0056] In some embodiments of the present invention, Figures 2 to 5 As shown, the first portion 21 and the second portion 22 are connected in a foldable manner. The first portion 21 and the second portion 22 are arranged in a foldable structure so that they can be unfolded when in use and folded and stored when not in use.
[0057] Specifically, the first portion 21 and the second portion 22 may be connected via a connecting portion 23 , and the connecting portion 23 may be a rotating shaft or a pin.
[0058] It should be understood that the connecting portion 23 connects the first part 21 and the second part 22, the folding action can be achieved by rotation, and a certain damping force is set at the connection position between the connecting portion 23 and the first part 21 and the second part 22, so that the first part 21 and the second part 22 can maintain their positions after folding and unfolding.
[0059] In some embodiments of the present invention, Figures 2 to 5 As shown, the first portion 21 is provided with a plurality of second elastic protrusions 211, which are spaced apart on the first portion 21 and are configured to abut against the outer surface of the patient's nose. The provision of the plurality of second elastic protrusions 211 further increases the frictional force on the outer surface of the patient's nose, thereby further improving the stability of the fixing device 100 and thus further enhancing the stability of the nasogastric feeding tube 200.
[0060] It should be understood that the plurality of second elastic protrusions 211 may be evenly distributed or unevenly distributed on the first portion 21 .
[0061] In some embodiments of the present invention, Figures 2 to 5 As shown, the second portion 22 is provided with a plurality of third elastic protrusions 221, which are spaced apart on the second portion 22 and are configured to abut against the inner surface of the patient's nostrils. The provision of the plurality of third protrusions further increases the frictional force on the inner surface of the patient's nostrils, thereby further improving the stability of the fixing device 100 and further enhancing the stability of the nasogastric feeding tube 200.
[0062] It should be understood that the plurality of third protrusions may be evenly distributed or unevenly distributed on the second portion 22 .
[0063] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
