[0039] In the field of medical devices, nutritional infusion devices, such as enteral nutrition pumps, are used to provide liquid nutrition for patients who are unable to eat. An enteral nutrition pump system typically includes a nutritional infusion device and a replaceable nutritional infusion tube set, which is used to pump only a liquid nutrition formula or to pump a nutrition formula and water separately. In use, the nutritional infusion tube set needs to be installed on the nutritional infusion device. In the existing installation process, the nutritional infusion tube set needs to be stretched to a certain extent before being fixed. Since the nutritional infusion tube set has a resilience, the elastic resistance of the nutritional infusion tube set needs to be overcome during the stretching process of the nutritional infusion tube set, so the installation process is very laborious.

[0040] The present application provides a nutritional infusion device, a nutritional infusion tube set, and a nutritional infusion system. By providing a guide groove and a support structure in the nutritional infusion device and a guide rail in the nutritional infusion tube set, under the cooperation of the guide groove and the guide rail, the elastic resistance generated by stretching the nutritional infusion tube set is reduced to interfere with the assembly process, and the support structure enables the nutritional infusion tube set to be stably assembled to the nutritional infusion device, ensuring the normal operation of the nutritional infusion system having the above-mentioned nutritional infusion device and nutritional infusion tube set. The embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0041] Figure 1 FIG. 4 is a schematic structural diagram of a nutritional infusion device 1 provided by an embodiment of the present application. Figure 4 FIG. 5 is a schematic structural diagram of a nutritional infusion tube set 5 provided by an embodiment of the present application. Figure 8 FIG. 6 is a schematic structural diagram of a nutritional infusion system 10 provided by an embodiment of the present application. Figure 11 FIG. 7 is a schematic working system diagram of the roller in the embodiment of the present application. With reference to Figure 1 、 Figure 4 、 Figure 8 and Figure 11 shown, the nutritional infusion device 1 can be used in combination with the nutritional infusion tube set 5. The nutritional infusion device 1 may include a housing 2, a power supply and control component, a driving component, a roller 3, and a first fixing member 4; the driving component is connected to the power supply and control component, and both can be disposed inside the housing 2; the roller 3 can be connected to the driving component and exposed on the mounting panel 21 of the housing 2; the roller 3 can be used for the peristaltic tube 51 of the nutritional infusion tube set 5 to be sleeved therein, and driven by the driving component, drive a plurality of rotors 31 disposed in the roller 3 to sequentially squeeze the peristaltic tube 51, so that the liquid in the peristaltic tube 51 moves in a specific direction; wherein, a guide rail 22 may be provided on the mounting panel 21, and the guide rail 22 can be used to provide a guiding function for the movement of the nutritional infusion tube set 5 relative to the mounting panel 21 after the peristaltic tube 51 of the nutritional infusion tube set 5 is sleeved on the roller 3 and before it is fixed to the first fixing member 4, for example, the movement on the mounting panel 21.

[0042] By providing a guide rail 22 on the mounting panel 21 of the housing 2, after the peristaltic tube 51 of the nutritional infusion tube set 5 is sleeved on the roller 3, the influence of the resilience force received by the nutritional infusion tube set 5 can be limited in the extending direction of the guide rail 22 under the action of the guide rail 22, that is, the components of the resilience force in other directions can be offset by the guide rail 22, so that the nutritional infusion tube set 5 only needs to receive a force in the extending direction of the guide rail 22 to be smoothly installed on the nutritional infusion device 1.

[0043] Figure 2 FIG. Figure 1 FIG. 8 is a partial enlarged structural diagram of the A position in FIG. 7. With reference to Figure 2 、Figure 1 and Figure 4 As shown in Figure 1 and Figure 4 , in a possible implementation, the mounting panel 21 is provided with a groove 211. At least part of the wall of the groove 211 can be used to abut at least partially against the substrate 6 after the substrate 6 of the nutrient infusion tube set 5 is fixed to the first fixing member 4. Schematically, the guide groove 63 provided on the substrate 6 can abut against at least part of the wall of the groove 211, or other parts of the substrate 6 except the guide groove 63 can abut against at least part of the wall of the groove 211. By providing the groove 211 on the mounting panel 21, after the nutrient infusion tube set 5 is installed on the nutrient infusion device 1, at least part of the wall of the groove 211 can provide a supporting force for the substrate 6 of the nutrient infusion tube set 5. Schematically, the direction of the supporting force can be from the roller 3 to the first fixing member 4. At the same time, the clamping groove 41 in the first fixing member 4 can generate an abutting force on the corresponding structure of the nutrient infusion tube set 5, such as the buckle 71. The direction of the abutting force can be parallel or intersect with the plane where the mounting panel 21 is located. Under the combined action of the supporting force and the abutting force, that is, the combined action of the groove 211 and the first fixing member 4, the nutrient infusion tube set 5 can be prevented from falling off the nutrient infusion device 1 during operation.

[0044] Combined with Figure 1 , Figure 2 and Figure 4 As shown in Figure 1 , Figure 2 and Figure 4 , in a possible implementation, the first fixing member 4 can include a clamping groove 41, and the second fixing member 7 can include a buckle 71. During the process of the substrate 6 moving along the guide rail 22, while the substrate 6 generates a displacement in the direction towards the inside of the housing 2, the top of the buckle 71 can be deformed by the extrusion of the clamping groove 41 and rebound when reaching the opening of the clamping groove 41, so that the clamping groove 41 and the buckle 71 can be fixed to each other. Schematically, when the guide groove 63 moves along the guide rail 22 provided in the area of the mounting panel 21 without the groove 211, there can be a dislocation between the buckle 71 and the clamping groove 41 in the direction from the roller 3 towards the first fixing member 4. When the guide groove moves along the guide rail 22 provided in the groove 211, the buckle 71 and the clamping groove 41 can be aligned in the direction from the roller 3 towards the first fixing member 4. When at least part of the substrate 6 abuts against at least part of the wall of the groove 211, the buckle 71 of the nutrient infusion tube set 5 can be snap-connected to the clamping groove 41. Under the combined action of the supporting force provided by the groove 211 and the abutting force generated between the buckle 71 and the clamping groove 41, the stability of the matching structure between the nutrient infusion tube set 5 and the nutrient infusion device 1 can be improved.

[0045] Combined with Figure 1 , Figure 2 and Figure 4As shown, in a possible implementation, the guide rail 22 may include a first guide rail 221 and a second guide rail 222. The first guide rail 221 may be closer to the roller 3 than the second guide rail 222. The direction in which the roller 3 faces the first fixing member 4 is defined as the first direction. Both the first guide rail 221 and the second guide rail 222 may extend parallel to each other along the first direction and be staggered. Schematically, a columnar connecting member may be provided between the first guide rail 221 and the second guide rail 222. The direction of the connecting member connecting one end of the first guide rail 221 and the other end of the second guide rail 222 may face the groove 211. The connecting member may cause the first guide rail 221 and the second guide rail 222, both extending along the first direction, to be misaligned with each other. Alternatively, the first guide rail 221 and the second guide rail 222 may be continuously arranged along the first direction, that is, the first guide rail 221 and the second guide rail 222 may be connected end to end. The first guide rail 221 and the second guide rail 222 may have different slopes respectively. From the end of the second guide rail 222 connecting the first guide rail 221 to the end of the second guide rail 222 away from the first guide rail 221, the second guide rail 222 may face the groove 211. The above structure is beneficial for the nutrition infusion tube set 5 to smoothly move along the first guide rail 221 and transition to the second guide rail 222 after being sleeved on the roller 3. After the nutrition infusion tube set 5 moves along the second guide rail 222 and is installed and fixed to the first fixing member 4, it can be supported by at least part of the wall of the groove 211 to prevent the part of the nutrition infusion tube set 5 fixed to the nutrition infusion device 1 from falling off during operation.

[0046] Figure 3 is a schematic diagram of the cooperation structure between the guide rail 22 and the mounting panel 21 in the embodiment of the present application, in combination with Figure 2 and Figure 3 As shown, in a possible implementation, one end of the first guide rail 221 away from the second guide rail 222 may be the first end 2213, and one end of the first guide rail 221 connecting the second guide rail 222 may be the second end 2214. From the first end 2213 to the second end 2214, along the direction perpendicular to the mounting panel 21, the length of the first guide rail 221 may show a decreasing trend. Schematically, the first guide rail 221 may be in a semi-trapezoidal shape. This can make the height of the first guide rail 221 gradually decrease along the direction towards the first fixing member 4, which is beneficial for the guide groove to transition from the first guide rail 221 to the second guide rail 222 when installing the nutrition infusion tube set.

[0047] Figure 5 is Figure 4 a partial enlarged structural diagram at B in Figure 5 , Figure 1 , Figure 2 and Figure 4As shown, in a possible implementation, the first guide rail 221 and the second guide rail 222 can be arranged in a stepped manner on the mounting panel 21. When there is a groove 211 on the mounting panel 21, in order to enable the guide groove 63 to obtain support on both the part of the mounting panel 21 without the groove 211 and the inner wall of the groove 211 when the guide groove 63 moves along the guide rail 22, it is necessary to match the corresponding depth of the guide groove 63 with the maximum height of the guide rail 22, that is, the distance between the outermost side of the second guide rail 222 and the bottom wall of the groove 211. However, by arranging the first guide rail 221 and the second guide rail 222 in a stepped manner on the mounting panel 21, while ensuring that at least part of the wall of the groove 211 can provide a supporting force for the nutrition infusion tube set 5, the maximum height of the guide rail 22 can be reduced, and further the corresponding depth of the guide groove 63 of the nutrition infusion tube set 5 can be reduced, which can make the matching structure of the nutrition infusion tube set 5 and the nutrition infusion device 1 more compact.

[0048] Combined with Figure 3 、 Figure 4 and Figure 5 As shown, in a possible implementation, the first carrier plate 23 and the second carrier plate 24 can be respectively arranged on the opposite sides of the first guide rail 221. The bearing surfaces of the first carrier plate 23 and the second carrier plate 24, that is, the surfaces in contact with the guide groove 63, can both face away from the mounting panel 21, and the extending directions of the first carrier plate 23 and the second carrier plate 24 can be the same as the first direction. Schematically, the first guide rail 221 can have a first surface 2211 and a second surface 2212 facing in opposite directions. The first surface 2211 and the second surface 2212 can be respectively arranged on the opposite sides of the first guide rail 221, and the first carrier plate 23 and the second carrier plate 24 can be respectively arranged on the first surface 2211 and the second surface 2212. By respectively arranging the first carrier plate 23 and the second carrier plate 24 on the opposite sides of the first guide rail 221, when the guide groove 63 moves along the guide rail 22, it can contact the bearing surfaces of the first carrier plate 23 and the second carrier plate 24, so that the first carrier plate 23 and the second carrier plate 24 can provide support for the guide groove 63, which is beneficial to the smooth assembly of the nutrition infusion tube set 5 along the guide rail 22 on the nutrition infusion device 1.

[0049] Combined with Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, in a possible implementation, on opposite sides of one end of the first guide rail 221 away from the second guide rail 222, a first baffle 25 and a second baffle 26 can be provided. The blocking surfaces of the first baffle 25 and the second baffle 26 can both face the first fixing member 4. Schematically, the first baffle 25 and the second baffle 26 can be respectively arranged on opposite sides of the first end 2213 along the direction parallel to the mounting panel 21. When the peristaltic tube 51 of the nutrient infusion tube set 5 is sleeved on the roller 3, the guide groove 63 of the nutrient infusion tube set 5 can be preliminarily sleeved with the first guide rail 221 under the support of the first baffle 25 and the second baffle 26, so as to avoid the interference of the elastic restoring force of the nutrient infusion tube set 5 during the preliminary sleeving stage of the guide groove 63 and the guide rail 22, which is beneficial to the subsequent assembly of the nutrient infusion tube set 5 along the guide rail 22 onto the nutrient infusion device 1.

[0050] Combined with Figure 1 、 Figure 4 and Figure 8 As shown, in a possible implementation, the nutrient infusion device 1 can further include a fastener 27 and a stopper 28. The fastener 27 can be located between the guide rail 22 and the roller 3. The fastener 27 can be in contact with the surfaces of the first baffle 25 and the second baffle 26 facing away from the first fixing member 4. The fastener 27 can have a tube groove 271. The stopper 28 can partially cover the opening of the tube groove 271. Schematically, the opening can include a first opening 2711 along the length direction of the tube groove 271 and two second openings 2712 at the upper and lower ends of the tube groove 271. Thus, the stopper 28 can partially cover the first opening 2711 or partially cover the second opening 2712.

[0051] By providing the fastener 27 and the stopper 28 in the nutrient infusion device 1, where the fastener 27 can be located between the guide rail 22 and the roller 3 and can have a tube groove 271, after the nutrient infusion tube set 5 is installed on the nutrient infusion device 1, the infusion tube 52 can be partially nested in the tube groove 271, which is beneficial to the installation stability of the nutrient infusion tube set 5; by making the fastener 27 in contact with the surfaces of the first baffle 25 and the second baffle 26 facing away from the first fixing member 4, the gap between the fastener 27 and the first baffle 25 and the second baffle 26 can be eliminated, which is beneficial to improving the structural compactness of the nutrient infusion device 1 and avoiding the situation of cleaning the remaining nutrient solution drops flowing into the gap; by making the stopper 28 partially cover the opening of the tube groove 271, after a part of the infusion tube 52 is nested in the tube groove 271, the stopper 28 can prevent the infusion tube 52 in the tube groove 271 from coming out, which is beneficial to the stability of the cooperation structure between the nutrient infusion tube set 5 and the nutrient infusion device 1.

[0052] Combined with Figure 2 、 Figure 4 and Figure 5As shown, in a possible implementation, the guide rail 22 may further include a third guide rail 223. The third guide rail 223 may connect the first guide rail 221 and the second guide rail 222, and the extending direction of the third guide rail 223 may be towards the mounting panel 21. By providing the third guide rail 223 in the guide rail 22, where the third guide rail 223 connects the first guide rail 221 and the second guide rail 222, the guide groove 63 of the nutrition infusion tube set 5 can smoothly transition from the first guide rail 221 to the second guide rail 222 through the third guide rail 223. By making the extending direction of the third guide rail 223 towards the mounting panel 21, after the nutrition infusion tube set 5 is assembled to the nutrition infusion device 1 along the second guide rail 222, the third guide rail 223 can provide certain support for the substrate 6 provided with the guide groove 63, which is beneficial to the stability of the cooperation structure between the nutrition infusion tube set 5 and the nutrition infusion device 1.

[0053] Combined with Figure 2 、 Figure 3 and Figure 5As shown, in a possible implementation, the mounting panel 21 may include a mounting surface 212 and a groove 211. The mounting surface 212 can be used to provide a bearing space for the substrate 6 of the nutrition infusion tube set 5 to enter the guide rail 22, and the groove 211 can be used to provide a bearing space after the substrate 6 of the nutrition infusion tube set 5 is fixed to the first fixing member 4. The guide rail 22 can be arranged in the middle of the mounting surface 212 and the groove 211, dividing the mounting surface 212 into a first mounting surface 2121 and a second mounting surface 2122, and dividing the groove 211 into a first groove 2111 and a second groove 2112, which is more conducive to maintaining balance during the process of moving the nutrition infusion tube set 5. It should be noted that the guide rail 22 can not only be arranged in the middle of the mounting surface 212 and the groove 211, that is, the guide rail 22 divides the mounting panel 21 into two parts with equal areas, but also can be arranged at the 1 / 4 position of the mounting panel 21, that is, dividing the mounting panel 21 into two parts with an area ratio of 1:3, etc. According to actual needs, the guide rail 22 can be arranged at any position on the mounting panel 21 as long as the guide rail 22 can enable the left and right sides of the nutrition infusion tube set 5 to be assembled to the nutrition infusion device 1 smoothly and evenly. By providing the mounting surface 212 in the mounting panel 21, during the initial fitting stage of the guide groove 63 of the nutrition infusion tube set 5 and the guide rail 22 of the nutrition infusion device 1, the guide groove 63 can partially contact the mounting surface 212 to obtain the supporting force of the mounting surface 212, which is conducive to the realization of the initial fitting of the guide groove 63 and the guide rail 22. By providing the groove 211 in the mounting panel 21, after the nutrition infusion tube set 5 is assembled and connected to the nutrition infusion device 1, at least part of the wall of the groove 211 can provide support for the substrate 6 provided with the guide groove 63, which is conducive to the stability of the cooperation structure between the nutrition infusion tube set 5 and the nutrition infusion device 1. By arranging the guide rail 22 in the middle of the mounting surface 212 and the groove 211, the elastic resistance received by the nutrition infusion tube set 5 can be symmetrically distributed, thereby reducing the thrust required for the nutrition infusion tube set 5 to move along the guide rail 22, which is conducive to the nutrition infusion tube set 5 being smoothly assembled to the nutrition infusion device 1 along the guide rail 22.

[0054] In a possible implementation, the second guide rail 222 can be located within the groove 211. The second guide rail 222 can have a third surface 2221 facing the first groove 2111 and a fourth surface 2222 facing the second groove 2112. The third surface 2221 can be connected to both the inner wall and the bottom wall of the first groove 2111, and the fourth surface 2222 can be connected to both the inner wall and the bottom wall of the second groove 2112.

[0055] See Figure 1, in a possible implementation, the mounting panel 21 can be integrally formed with the guide rail 22. By integrally forming the guide rail 22 with the mounting panel 21, the gap between the guide rail 22 and the mounting panel 21 can be eliminated to prevent nutrient solution from flowing into the gap and causing contamination, which can reduce the cleaning difficulty of the nutritional infusion device 1.

[0056] The structure of the nutritional infusion device 1 is introduced in detail above. Next, the detailed structure of the nutritional infusion tube set 5 will be introduced.

[0057] Combined with Figure 1 、 Figure 4 and Figure 5 shown, the nutritional infusion tube set 5 can include a peristaltic tube 51, an infusion tube 52, an input tube connector 53, an output tube connector 54, a substrate 6, and a second fixing member 7. The infusion tube 52 can include an input tube 521 and an output tube 522. The input tube connector 53 can be connected to one end of the input tube 521 and the peristaltic tube 51, and the output tube connector 54 can be connected to one end of the output tube 522 and the peristaltic tube 51. The substrate 6 can be provided with a first mounting groove 61, a second mounting groove 62, and a guide groove 63. The first mounting groove 61 can be used to receive the input tube connector 53, the second mounting groove 62 can be used to receive the output tube connector 54, and the guide groove 63 can be arranged between the first mounting groove 61 and the second mounting groove 62 for cooperating with the guide rail 22 of the nutritional infusion device 1 to provide a guiding effect during the movement of the substrate 6. The second fixing member 7 can be fixedly connected to the side of the substrate 6 facing away from the peristaltic tube 51.

[0058] By providing the peristaltic tube 51, the input tube 521, the output tube 522, the input tube connector 53, the output tube connector 54, the substrate 6, and the second fixing member 7 in the nutritional infusion tube set 5, wherein the substrate 6 can be provided with the first mounting groove 61 and the second mounting groove 62, so that the input tube connector 53 connecting one end of the input tube 521 and the peristaltic tube 51 can be received by the first mounting groove 61, and the output tube connector 54 connecting one end of the output tube 522 and the peristaltic tube 51 can be received by the second mounting groove 62. Furthermore, the infusion tube 52 including the input tube 521 and the output tube 522 can be stably arranged on the substrate 6. By providing the guide groove 63 on the substrate 6, after the peristaltic tube 51 is sleeved on the roller 3 of the nutritional infusion device 1, the nutritional infusion tube set 5 can be limited in the extending direction of the guide rail 22 under the cooperation of the guide groove 63 and the guide rail 22 due to the influence of the resilience force, that is, the components of the resilience force in other directions can be offset by the cooperation of the guide groove 63 and the guide rail 22. Furthermore, the nutritional infusion tube set 5 only needs to be subjected to the force in the extending direction of the guide rail 22 to be smoothly installed on the nutritional infusion device 1.

[0059] Figure 6 is Figure 4An exploded view of the nutrition infusion tube set 5 in Figure 7 is Figure 4 another exploded view of the nutrition infusion tube set 5 in Figure 5 , Figure 6 and Figure 7 As shown, in a possible implementation, the nutrition infusion tube set 5 may further include a first mounting member 55 and a second mounting member 56. The first mounting member 55 may be fixedly connected to the input tube connector 53. A first locking member 64 may be provided on the inner wall of the first mounting groove 61, and a detachable connection may be formed between the first mounting member 55 and the first locking member 64. The second mounting member 56 may be fixedly connected to the output tube connector 54. A second locking member 65 may be provided on the inner wall of the second mounting groove 62, and a detachable connection may be formed between the second mounting member 56 and the second locking member 65. Schematically, both the first locking member 64 and the second locking member 65 may have locking surfaces. After the first mounting member 55 and the second mounting member 56 enter the first mounting groove 61 and the second mounting groove 62 respectively, the locking surfaces may form a locking relationship with the first mounting member 55 and the second mounting member 56, which can enhance the connection strength of the input tube connector 53 connected to the first mounting groove 61 and the connection strength of the output tube connector 54 connected to the second mounting groove 62, so as to prevent the input tube 521 and the output tube 522 from falling off the first mounting groove 61 and the second mounting groove 62 respectively, and ultimately contribute to the stability of the cooperation structure between the infusion tube 52 and the substrate 6.

[0060] The above introduced a nutrition infusion tube set 5 with a three-groove structure having a first mounting groove 61, a second mounting groove 62 and a guide groove 63. Next, the cooperation structure formed after the nutrition infusion tube set 5 is assembled to the nutrition infusion device 1 will be described.

[0061] Figure 8 is a schematic structural diagram of a nutrition infusion system 10 provided by an embodiment of the present application, Figure 9 is a schematic diagram of the cooperation structure between the roller 3 and the peristaltic tube 51 of an embodiment of the present application, Figure 10 is an exploded view of the cooperation structure between the guide rail 22 and the guide groove 63 of an embodiment of the present application. As shown in combination with Figure 8 , Figure 9 and Figure 10 , the nutrition infusion system 10 may include a nutrition infusion device 1 and a nutrition infusion tube set 5. The mounting panel 21 may face the substrate 6. The peristaltic tube 51 may be sleeved on the rotor 31 of the roller 3. The guide rail 22 may be in contact with the inner wall of the guide groove 63. The first fixing member 4 may form a detachable connection with the second fixing member 7.

[0062] By arranging the nutrition infusion device 1 and the nutrition infusion tube set 5 proposed in this application in the nutrition infusion system 10, wherein the mounting panel 21 can face the substrate 6, the peristaltic tube 51 can be sleeved on the rotor 31 of the roller 3, and the guide rail 22 can be in contact with the inner wall of the guide groove 63. During the process of stretching the nutrition infusion tube set 5 to further assemble it on the nutrition infusion device 1, the cooperation between the guide groove 63 and the guide rail 22 can reduce the interference degree of the elastic resistance on the assembly process, so that the nutrition infusion tube set 5 only needs to be subjected to the force along the extension direction of the guide rail 22 to smoothly reach the final assembly position on the nutrition infusion device 1. Then, the first fixing member 4 and the second fixing member 7 are detachably connected. Illustratively, after the nutrition infusion tube set 5 slides along the guide rail 22, the buckle 71 of the second fixing member 7 can enter the card slot 41 of the first fixing member 4, and then can form a snap connection with the card slot 41. In addition, at least part of the wall of the groove 211 of the nutrition infusion device 1 can provide a supporting effect for at least part of the guide groove 63, which can realize a reliable cooperative working structure between the nutrition infusion tube set 5 and the nutrition infusion device 1, that is, the nutrition infusion system 10, and ensure the normal operation of the nutrition infusion system 10.

Any person skilled in the art within the technical scope disclosed in this application can easily think of changes or substitutions, which should all be covered within the protection scope of this application. Therefore, the protection scope of this application should be subject to the protection scope of the claims.
