[0057] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0058] Nutrition pumps are one of the more commonly used medical devices, mainly used to pump nutrient solution into the patient's intestinal system, thereby improving the patient's nutritional status. Specifically, the nutrition pump mainly drives the nutrient solution in the infusion pipeline assembly to flow in a directional manner, thereby pumping the nutrient solution in the infusion pipeline assembly into the patient's intestinal system. In the related art, different types of nutrition pumps can only work with corresponding infusion pipeline assemblies, resulting in poor versatility of nutrition pumps.

[0059] Based on this, please refer to Figure 1 and Figure 2 , Figure 1 A schematic diagram of the structure of a nutrition pump provided in an embodiment of the present application, Figure 2 for Figure 1A schematic structural diagram of the first fixing component of the nutrition pump is shown. An embodiment of the present application provides a nutrition pump, comprising a housing 100, an extrusion component 200 and a first fixing component 300. The extrusion component 200 is disposed on the housing 100, and the extrusion component 200 is used to extrude the infusion pipeline assembly so that the liquid in the infusion pipeline assembly flows along a preset direction. The first fixing component 300 and the extrusion component 200 are disposed on the same housing side wall of the housing 100. The first fixing component 300 is provided with a first through hole 31, one end of the first through hole 31 faces the extrusion component 200, and the inner wall of the first through hole 31 includes a support surface 32, a first side wall 33 and a second side wall 34. The support surface 32 is used to support the clamping portion of the infusion pipeline assembly to limit the clamping portion from moving in a direction close to the extrusion component 200. The end of the first side wall 33 facing away from the extrusion component 200 is connected to the support surface 32. One end of the second side wall 34 facing the extrusion component 200 is connected to the support surface 32, or it can be simply understood that the adjacent ends of the first side wall 33 and the second side wall 34 form a limiting step through the support surface 32. The second side wall 34 includes a first portion 341 and a second portion 342, which are arranged along the circumference of the first through hole 31, and the curvature and / or shape of the first portion 341 is different from the curvature and / or shape of the second portion 342, so that the space formed between the second side wall 34 and the support surface 32 can accommodate at least two different specifications of the clamping parts of the infusion pipeline assembly.

[0060] Then, when the nutrition pump is actually working, the support surface 32 is used for limiting, so that the accurate position of the infusion line assembly in the length direction can be ensured to be placed on the first fixing component 300, thereby ensuring that the extrusion component 200 can squeeze the accurate position of the infusion line assembly, and finally ensuring the infusion accuracy of the nutrition pump. At the same time, different types of infusion line assemblies can also be placed through the first part 341 and the second part 342 of the second side wall 34, so that the nutrition pump can adapt to more infusion line assemblies of different specifications. It can be seen that the nutrition pump of the embodiment of the present application has the advantage of good general performance on the basis of meeting the actual demand for infusion accuracy.

[0061] It is understandable that the second side wall 34 may also include at least three, such as three, four, five or six different parts, and the different parts are respectively used to adapt to the clamping parts of the infusion pipeline assembly of different specifications. Then, any two of the parts can be respectively regarded as the first part 341 and the second part 342 mentioned above, so that the nutrition pump can adapt to more types of infusion pipeline assemblies, which is not limited in the embodiment of the present application.

[0062] In some embodiments, the first part 341 and the second part 342 may differ in only one of shape and curvature, or may differ in both shape and curvature, which is not limited in the present embodiment. Thus, at least two different parts are formed on the second side wall 34, so that different specifications of the clamping parts can be selectively placed on the first part 341 or the second part 342 according to the specific specifications of the infusion pipeline assembly.

[0063] In some embodiments, the side of the first portion 341 away from the extruded component 200 may have a first contour line, and the side of the second portion 342 away from the extruded component 200 may have a second contour line, and the curvature and / or shape of the first contour line is different from the curvature and / or shape of the second contour line.

[0064] For example, the first fixing component 300 has an upper surface facing away from the extruding component 200, and the contour line of the first portion 341 at the upper surface, namely the first contour line, and the contour line of the second portion at the upper surface, namely the second contour line, have different curvatures and / or shapes.

[0065] In some embodiments, along a direction approaching the extrusion member 200 , at least one of the first portion 341 and the second portion 342 may be inclined toward a direction approaching an axial center line of the first through hole 31 .

[0066] Please continue to refer to Figure 3 , Figure 3 for Figure 1 The schematic diagram of the nutrition pump installed with the first specification of the infusion pipeline assembly is shown. Below, the structure of the infusion pipeline assembly 700 and the infusion principle are explained as a whole. The infusion pipeline assembly 700 may include a first pipeline 71, a pipeline connector 72 and a second pipeline 73 that are connected in sequence. During use, the inlet end of the first pipeline 71 is used to communicate with a liquid container such as an infusion bag. The outlet end of the second pipeline 73 is used to inject nutrient solution into the patient's body, and the material of the second channel can be a silicone tube and a PVC tube in turn. For example, the middle part of the second pipeline 73 is installed to the extrusion component 200 of the nutrition pump, and the extrusion component 200 squeezes the second pipeline 73 so that the liquid in the second pipeline 73 moves forward to be injected into the patient's body, thereby realizing the function of driving the liquid in the infusion pipeline assembly 700 to flow in a preset direction.

[0067] Generally, different specifications of the infusion pipeline assembly 700 will connect one or more first pipelines 71 to the second pipeline 73 through different types of pipeline connectors 72. Then, in the embodiment of the present application, the pipeline connectors 72 of the infusion pipeline assembly 700 of different specifications can be used as the clamping part, or the first part 341 and the second part 342 are respectively used to place different types of pipeline connectors 72 in the infusion pipeline assembly 700, so that the space formed between the second side wall 34 and the support surface 32 can place at least two different specifications of the clamping parts of the infusion pipeline assembly 700.

[0068] Exemplarily, the clamping portion may include a drip pot 72 a , and the space enclosed by the first portion 341 and the supporting surface 32 is used to place the drip pot 72 a .

[0069] Specifically, the drip pot 72a is also called an intravenous drip pot or a drip bucket, which has the function of discharging the gas in the lumen before infusion and monitoring the dripping speed of the infusion, and can also be used to add drugs, etc. Therefore, by clamping and fixing the drip pot 72a through the first part 341, the gas in the infusion pipeline assembly 700 can be discharged more stably, and it is convenient to detect the dripping speed of the infusion.

[0070] In addition, in the infusion pipeline assembly 700, the first pipe 71 and the second pipe 73 are usually deformable to a certain extent. Therefore, if a certain part of the first pipe 71 is used as the clamping part, during the process of squeezing the second pipe 73 by the squeezing component 200, the first pipe 71 and the second pipe 73 are easily deformed, thereby affecting the infusion accuracy of the squeezing component 200. In contrast, the drip pot 72a is usually hard, so by clamping and fixing the drip pot 72a, the influence of the deformation of the first pipe 71 on the injection accuracy of the squeezing component 200 can be further avoided.

[0071] Please continue to refer to Figure 4 , Figure 4 for Figure 2 The first portion 341 may include a plurality of first sub-portions 3411. The plurality of first sub-portions 3411 are arranged along the circumference of the first through hole 31, and the plurality of first sub-portions 3411 are coaxially arranged.

[0072] Furthermore, the plurality of first sub-portions 3411 are arranged to form a space for clamping the drip pot 72a. Thus, the plurality of first sub-portions 3411 can block the drip pot 72a from different positions on the outer peripheral side of the drip pot 72a to limit the radial movement of the drip pot 72a along the first through hole 31. At the same time, the extrusion component 200 pulls the second pipe 73, and the support surface 32 limits the movement of the drip pot 72a in the direction close to the extrusion component 200, so that the drip pot 72a can be fixed in multiple dimensions.

[0073] Exemplarily, a first notch 35 is provided on the inner wall of the first through hole 31 on the side facing away from the shell 100, so that the infusion tube assembly 700 can enter or leave the first through hole 31 from the first notch 35, thereby facilitating the user to directly hang the infusion tube assembly 700 into the first through hole 31 for clamping.

[0074] Correspondingly, a first sub-portion 3411 may be provided at both opening ends of the first notch 35; at least one first sub-portion 3411 is located on the side of the second side wall 34 facing the first notch 35. Thus, the three first sub-portions 3411 respectively support the drip pot 72a from three positions on the circumference of the drip pot 72a to completely restrict the radial movement of the drip pot 72a along the first through hole 31.

[0075] Please continue to refer to Figure 4 and Figure 5 , Figure 5 for Figure 1 The schematic diagram of the nutrition pump being installed with the infusion pipeline assembly of the second specification is shown. In some embodiments, the clamping portion includes a three-way connector 72b, and the space enclosed by the second portion 342 and the support surface 32 is used to place the three-way connector 72b.

[0076] Specifically, the three-way joint 72b is a joint including two liquid inlets and one liquid outlet. The liquid outlet of the three-way joint 72b is connected to the inlet of the second pipeline 73. The two liquid inlets of the three-way joint 72b are respectively connected to different first pipelines 71, so that different first pipelines 71 can be connected to different liquid containers, so that the three-way connection can inject two target liquids into the second pipeline 73, and the extrusion component 200 injects the target liquid in the second pipeline 73 into the patient's body.

[0077] It is understandable that in the infusion pipeline assembly 700, the first pipe 71 and the second pipe 73 are usually deformable to a certain extent. Therefore, if a certain part of the first pipe 71 is used as the clamping part, during the process of the extrusion component 200 squeezing the second pipe 73, the first pipe 71 and the second pipe 73 are easily deformed, thereby affecting the infusion accuracy of the extrusion component 200. In contrast, the three-way connector 72b is usually hard, so by clamping and fixing the three-way connector 72b, it can further avoid the influence of the deformation of the first pipe 71 on the injection accuracy of the extrusion component 200.

[0078] In some embodiments, the second portion 342 may include two second sub-portions 3421 . The two second sub-portions 3421 are symmetrically arranged about the axis of the first through hole 31 .

[0079] Exemplarily, the second portion 342 may include two second sub-portions 3421. The two second sub-portions 3421 are arranged opposite to each other, and both of the two second sub-portions 3421 are arc-shaped and the axis lines of the two second sub-portions 3421 do not overlap, so that the space formed by the two second sub-portions 3421 can be clamped with the three-way connector 72b of the infusion pipeline assembly 700.

[0080] Of course, the second part 342 may include two second subparts 3421. The two second subparts 3421 are arranged opposite to each other, and both of the two second subparts 3421 are rectangular, so that the space formed by the two second subparts 3421 can be clamped with the three-way connector 72b of the infusion pipeline assembly 700.

[0081] It is understandable that, depending on the shape of the three-way connector 72b, the specific structure of the second sub-portion 3421 can be diverse, and the embodiment of the present application does not limit this.

[0082] In some embodiments, the housing sidewall provided with the first fixing member 300 includes a first surface 11. The two second sub-portions 3421 are respectively located on different sides of the first through hole 31 along the first direction H1. The first direction H1 is parallel to the first surface 11, and the first direction H1 is perpendicular to the direction of the first through hole 31 toward the extrusion member 200. The two inlets of the three-way joint 72b are arranged along the width direction of the three-way joint 72b, and each second sub-portion 3421 is used to clamp one end of the three-way joint 72b along the width direction.

[0083] Then, after the three-way connector 72b is snapped into the first through hole 31, the corresponding two first pipes 71 can be arranged in a direction parallel to the surface of the shell 100, so that the two first pipes 71 can be routed along the surface of the shell 100, thereby facilitating the subsequent snap-on fixation of the two first pipes 71 and saving space on one side of the first surface 11 of the shell 100.

[0084] It can also be understood that, in the first fixed component 300, the space formed by the first part 341 and the supporting surface 32 may be used to place the dripping pot 72a, and the space formed by the second part 342 and the supporting surface 32 may not be used to place the three-way joint 72b; or the space formed by the first part 341 and the supporting surface 32 may not be used to place the dripping pot 72a, and the space formed by the second part 342 and the supporting surface 32 may be used to place the three-way joint 72b; or the space formed by the first part 341 and the supporting surface 32 may be used to place the dripping pot 72a, and the space formed by the second part 342 and the supporting surface 32 may be used to place the three-way joint 72b. The embodiment of the present application does not limit this.

[0085] In some embodiments, the support surface 32 may be a flat plane, or a curved surface, or may be formed by splicing two, three or even four surfaces, which is not limited in the embodiments of the present application.

[0086] For example, please continue to refer to Figure 6 , Figure 6 for Figure 2 A schematic diagram of another supporting surface of the first fixing component is shown. The supporting surface 32 may include a first supporting surface 321 and a second supporting surface 322. The first supporting surface 321 is connected to the first portion 341 and the first side wall 33, respectively. The second supporting surface 322 is connected to the second portion 342 and the first side wall 33, respectively. The first supporting surface 321 and the second supporting surface 322 are mutually offset in the axial direction of the first through hole 31.

[0087] In some embodiments, the first fixing member 300 may be disposed on the housing 100 .

[0088] For example, the first fixing component 300 may be integrally formed with the housing 100 .

[0089] Optionally, the first fixing component 300 may also be detachably mounted on the housing 100. For example, the first fixing component 300 is connected to the housing 100 by snapping, screwing, or magnetic attraction, etc., which is not limited in the embodiment of the present application.

[0090] The above is an illustrative description of some aspects of the first fixing component 300 in the embodiment of the present application. The following will further illustrate the technical solution of the embodiment of the present application in combination with some other optional structures of the nutrition pump.

[0091] Please continue to refer to Figure 7 and Figure 8 , Figure 7 for Figure 1 The schematic diagram of the structure of the nutrition pump after the pipeline control components are set. Figure 8 for Figure 7 The schematic diagram of the installation position of the pipeline control component is shown. In some embodiments, the nutrition pump may further include a pipeline control component 400. The pipeline control component 400 is used to control the opening and closing of different pipelines in the infusion pipeline assembly 700.

[0092] In some embodiments, the pipeline control component 400, the extrusion component 200, and the first fixing component 300 are disposed on the same housing side wall of the housing 100, and the pipeline control component 400 is located on the side of the first through hole 31 away from the extrusion component 200. There is no overlap between the support surface 32 and the orthographic projection of the pipeline control component 400 on the bottom surface of the nutrition pump.

[0093] For example, the nutrition pump may include a front surface, a side surface, and a bottom surface. The front surface is located on the side of the nutrition pump for accepting user operations. For example, the front surface may be provided with at least one of a touch screen, a touch pad, a button, and a knob for the user to perform human-computer interaction operations. The side surface is located on the side where the first fixing component of the nutrition pump is provided. The bottom surface, the side surface, and the front surface are perpendicular to each other. For example, the front surface is the front side of the nutrition pump, the side surface is the left side of the nutrition pump, and the bottom surface is the bottom side of the nutrition pump.

[0094] Please continue to combine Fig. 9 , Fig. 9 for Figure 7 Schematic diagram of the pipeline control component cooperating with another specification of the infusion pipeline assembly. Then, taking one of the first part 341 and the second part 342 for placing the drip pot 72a and the other for placing the three-way connector 72b as an example, the embodiment of the present application can avoid the pipeline control component 400 from interfering with the end of the drip pot 72a away from the extrusion component 200, and finally, on the basis of the nutrient pump being provided with the pipeline control component 400, the first fixing component 300 can also be compatible with the infusion pipeline assembly 700 with the drip pot 72a.

[0095] On the other hand, when the three-way connector 72b is connected to the first fixing component 300, the two first pipes 71 can be switched on and off by the pipeline control component 400. For example, the first first pipe 71 is used to transport nutrient solution, and the second pipe is used to transport cleaning solution. The first pipe and the second pipe can be controlled to infuse solution in different time periods by the control component, so that the nutrient pump has two functions: cleaning and infusing nutrient solution.

[0096] In some embodiments, the pipeline control component 400 includes a cam, which is used to rotate to squeeze different pipelines connected to the three-way connector 72b, thereby controlling the opening and closing of different pipelines connected to the three-way connector 72b.

[0097] In some embodiments, the nutrition pump may further include a first motor which is in transmission connection with the pipeline control component 400 and drives the pipeline control component 400 to move to squeeze different pipelines in the infusion pipeline assembly 700, thereby limiting the flow of liquid inside the corresponding pipelines.

[0098] For example, the first motor can drive the pipeline control component 400 to move to the first position to squeeze the first first pipeline 71 and separate it from the second first pipeline 71, so that only the liquid in the second first pipeline 71 can be delivered to the three-way joint 72b; and the first motor can drive the pipeline control component 400 to move to the second position to squeeze the second first pipeline 71 and separate it from the first first pipeline 71, so that only the liquid in one first pipeline 71 can be delivered to the three-way joint 72b. In addition, the on-off of different pipelines can be controlled by a simple structure, and the liquid in different pipelines will not be contacted to avoid contamination of the liquid in different pipelines.

[0099] The first motor may drive the pipeline control component 400 to perform linear motion, may drive the pipeline control component 400 to perform curved motion, or may drive the pipeline control component 400 to rotate, which is not limited in the embodiments of the present application.

[0100] For example, the pipeline control component 400 may include a cam or an eccentric member, and the first motor drives the cam or the eccentric member to rotate, so that the pipeline control component 400 can move to squeeze different pipelines in the infusion pipeline assembly 700.

[0101] In some embodiments, the pipeline control component 400 further includes a first sensor. The first sensor is used to detect the position information of the pipeline control component 400. Thus, the position of the pipeline control component 400 can be detected by the first sensor to determine the on-off status of different pipelines.

[0102] The first sensor may be at least one of a photoelectric sensor, a rotary potentiometer, an infrared ranging sensor, a Hall sensor, and a micro switch, which is not limited in the embodiments of the present application.

[0103] In some embodiments, the first motor is also in transmission connection with the extrusion component 200 to drive the extrusion component 200. Thus, the extrusion component 200 and the pipeline control component 400 can be driven by one power source to simplify the structure of the nutrition pump and facilitate miniaturization and thinness of the nutrition pump.

[0104] In some embodiments, the first motor may be configured to drive the pressing component 200 and the pipeline control component 400 in a time-sharing manner.

[0105] For example, the output shaft of the first motor may be provided with two one-way bearings, so that the first motor can drive the two one-way bearings to rotate in opposite directions. One one-way bearing is transmission-connected to the extrusion component 200, and the other one-way bearing is transmission-connected to the pipeline control component 400. Therefore, when the output shaft of the first motor rotates forward, it can drive the extrusion component 200 to move without driving the pipeline control component 400 to move, and when the output shaft of the first motor rotates reversely, it can drive the pipeline control component 400 to move without driving the extrusion component 200 to move.

[0106] Optionally, the nutrient pump further includes a second motor, which is transmission-connected to the extrusion component 200 to drive the extrusion component 200 , so that the extrusion component 200 and the pipeline control component 400 can be independently controlled.

[0107] Of course, in some other embodiments, the pipeline control component 400 can also be movably installed on the shell 100 and manually operated by the user, so that the pipeline control component 400 can move to squeeze different pipelines in the infusion pipeline assembly 700, thereby limiting the flow of liquid inside the corresponding pipeline. The embodiment of the present application is not limited to this.

[0108] In some embodiments, the side wall of the shell provided with the pipeline control component 400 is also provided with an avoidance groove 12, and the pipeline control component 400 is at least partially arranged in the avoidance groove 12, so that there is no overlap between the support surface 32 and the orthographic projection of the pipeline control component 400 on the bottom surface of the nutrition pump. Then, it can also be understood that the outer surface of the shell 100 is partially recessed inward to form the avoidance groove 12 for installing the pipeline control component 400. It can also be understood that compared with the pipeline control component 400 protruding from one side of the first surface 11 and the first through hole 31 protruding more from the side of the first surface 11 relative to the pipeline component, the embodiment of the present application can make the overall structure of the nutrition pump smaller.

[0109] In some embodiments, the housing side wall provided with the pipeline control component 400 includes a first surface 11. The first fixing component 300 and the extrusion component 200 are provided on the first surface 11. The notch of the avoidance groove 12 is at least partially located on the first surface 11.

[0110] The housing top wall of the housing 100 is also provided with at least two clamping structures 13, at least two clamping structures 13 are connected with the avoidance groove 12, at least two clamping structures 13 are arranged opposite to each other on both sides of the pipeline control component 400, and the clamping structures 13 are used to clamp different pipelines of the infusion pipeline assembly 700. The top wall of the housing is the shell wall on the side opposite to the bottom surface of the housing, and the clamping structure on the top wall can tilt the pipeline of the pipeline assembly before the clamping part relative to the first surface, wherein each pipeline is tilted toward the inner side close to the nutrition pump as it approaches the top wall, so that the pipeline can contact the pipeline control component arranged in the avoidance groove.

[0111] For example, at least one clamping structure 13 is provided on each side of the pipeline control component 400 along the first direction H1, the first direction H1 is perpendicular to the axis of the first through hole 31 and parallel to the first surface 11, and the clamping structure 13 is used to clamp the pipeline of the infusion pipeline assembly 700.

[0112] Furthermore, after the three-way connector 72b is snapped into the first through hole 31, the two first pipes 71 connected to the three-way connector 72b can be arranged in a direction parallel to the surface of the shell 100, so that the two first pipes 71 can be routed along the surface of the shell 100, and then snapped into the two sides of the pipeline control component 400, thereby facilitating the movement of the pipeline control component 400 to squeeze different first pipes 71.

[0113] The above are some examples of the pipeline control component 400 in the embodiment of the present application. The following will continue to illustrate the technical solution of the embodiment of the present application in combination with some other optional structures of the nutrition pump.

[0114] Please continue to refer to Fig.10 , Fig.10 for Figure 1 The schematic diagram of the structure of the nutrition pump after the second fixing component is provided. In some embodiments, the nutrition pump further includes a second fixing component 600. The second fixing component 600 is located on the side of the first through hole 31 away from the extrusion component 200. The second fixing component 600 is provided with a second through hole 61. The hole wall of the second through hole 61 is provided with a first card groove 62, so that the second fixing component 600 can be placed with at least two different specifications of infusion pipeline components 700, so that the nutrition pump can be adapted to more different specifications of infusion pipeline components 700, so as to improve the versatility of the nutrition pump.

[0115] Exemplarily, the second through hole 61 is coaxially arranged with the first through hole 31, so that the first through hole 31 and the second through hole 61 can be clamped at different positions along the length direction of the drip pot 72a of the infusion pipeline assembly 700. Furthermore, by clamping multiple portions along the length direction of the drip pot 72a, the stability of the drip pot 72a during installation can be further improved.

[0116] Exemplarily, the number of the first slots 62 is at least two, and each first slot 62 is used to clamp the hose of the infusion pipeline assembly 700. For example, when the three-way connector 72b is clamped in the first through hole 31, the two first pipes 71 connected to the three-way connector 72b can be respectively clamped in one first slot 62, so that the infusion pipeline assembly 700 can be better fixed.

[0117] The hole wall of the second through hole 61 is further provided with a second slot 63 , the slot opening of the second slot 63 extends from the hole wall of the second through hole 61 to the slot wall of the first slot 62 , and the second slot 63 is used for installing a flow sensor.

[0118] Then, since the second card slot 63 is connected to the first card slot 62 and the second through hole 61 respectively, the flow sensor can be reused to detect the flow of the first pipe 71 connected to the second card slot 63 and the flow of the drip pot 72a connected to the second through hole 61. It can be seen that the nutrition pump of the embodiment of the present application can monitor the flow of multiple infusion pipeline assemblies 600, and the overall structure is simpler.

[0119] In some embodiments, the side wall of the housing provided with the second fixing member 600 includes a first surface 11. Along a direction parallel to the first surface 11, at least one first clamping groove 62 is provided on each side of the inner wall of the second through hole 61. Then, after the three-way connector 72b is clamped to the first through hole 31, the corresponding two first pipes 71 can be arranged along a direction parallel to the surface of the housing 100, so that the two first pipes 71 can be routed close to the surface of the housing 100, so as to avoid one of the pipes being too far away from the housing 100 and the corresponding clamping structure 13 needing to protrude to a position far from the first surface 11.

[0120] In some embodiments, a second notch 64 is provided on the inner wall of the second through hole 61 on the side facing away from the shell 100, so that the infusion tube assembly 700 can enter or leave the second through hole 61 from the second notch 64, thereby facilitating the user to directly hang the infusion tube assembly 700 into the second through hole 61 or the second slot 63 for clamping.

[0121] In some embodiments, the second fixing member 600 may be integrally formed with the housing 100 .

[0122] Optionally, the second fixing component 600 may also be detachably mounted on the housing 100; for example, the second fixing component 600 is snap-connected, screw-connected, or magnetically connected to the housing 100, which is not limited in the embodiment of the present application.

[0123] In some embodiments, the second fixing member 600 may be integrally formed with the first fixing member 300 .

[0124] Optionally, the second fixing component 600 may also be detachably mounted on the first fixing component 300; for example, the second fixing component 600 is snap-connected, screwed, or magnetically connected to the first fixing component 300, which is not limited in the embodiment of the present application.

[0125] In some embodiments, the squeezing component 200 may include a first roller and a plurality of squeezing members. The first roller is rotatably mounted on the housing 100 and is perpendicular to the first surface 11. The plurality of squeezing members are arranged along the first roller and are arranged at intervals along the peripheral edge of the first roller. Thus, the second pipe 73 of the infusion pipeline assembly 700 can be arranged around the outer peripheral side of the first roller, and when the first roller rotates, the squeezing component 200 can rotate synchronously to squeeze the liquid in the second pipe 73 to move forward.

[0126] In some embodiments, the extruder may include a second roller rotatably mounted on the first roller, wherein the axis of the first roller and the axis of the second roller are parallel to each other.

[0127] Of course, the extrusion component 200 can also be any structure in the prior art that drives the liquid in the pipeline to move forward through the pipeline, and the embodiment of the present application is not limited here.

[0128] Please continue to refer to Fig.11 and Fig.12 , Fig.11 This is a schematic structural diagram of another first fixing component of the nutrition pump provided in an embodiment of the present application. Fig.12 for Fig.11A top view of the first fixing component is shown. The embodiment of the present application also provides a nutrition pump, which includes a housing 100, an extrusion component 200 and a first fixing component 300. The extrusion component 200 is arranged on the housing 100, and is used to extrude the infusion pipeline assembly 700 so that the liquid in the infusion pipeline assembly 700 flows along a preset direction. The first fixing component 300 is provided with a first through hole 31 and an upper surface facing away from the extrusion component 200, one end of the first through hole 31 faces the extrusion component 200, and the inner wall of the first through hole 31 includes a first part 341 and a second part 342, and the first part 341 and the second part 342 are arranged along the circumference of the first through hole 31. The side of the first part 341 close to the upper surface has a first contour line, or the side of the first part 341 away from the extrusion component 200 has a first contour line, and the side of the second part 342 close to the upper surface has a second contour line, or the side wall of the second part away from the extrusion component 200 has a second contour line, and at least one of the curvature and shape of the first contour line and the second contour line is different. Along the direction close to the extrusion component 200, the first part 341 and the second part 342 are inclined toward the direction close to the axis of the first through hole 31, and the first part 341 and the second part 342 are respectively used to abut against the clamping parts of the infusion pipeline assembly 700 of different specifications, so that the space enclosed by the first part 341 and the second part 342 can clamp at least two infusion pipeline assemblies 700 of different specifications.

[0129] Then, when the nutrition pump is actually working, the extrusion component 200 can apply a force to the infusion line assembly 700 to pull the clamping part toward the direction close to the extrusion component 200. At this time, the inclined first part 341 or the second part 342 can limit the clamping part to move toward the direction close to the extrusion component 200, and can limit the radial movement of the clamping part along the first through hole 31, so that the accurate position of the infusion line assembly 700 in the length direction can be ensured to be clamped on the first fixed component 300, thereby ensuring that the extrusion component 200 can squeeze the accurate position of the infusion line assembly 700, and finally ensure the infusion accuracy of the nutrition pump. Further, the nutrition pump can also clamp different types of infusion line assemblies 700 through the first part 341 and the second part 342, so that the nutrition pump can adapt to more infusion line assemblies 700 of different specifications. It can be seen that the nutrition pump of the embodiment of the present application has the advantage of good general performance on the basis of meeting the actual demand for infusion accuracy.

[0130] It can also be understood that the inner wall of the first through hole 31 can also include at least three, such as three, four, five or six different parts, and the different parts are respectively used to abut against the clamping parts of the infusion pipeline assembly 700 of different specifications. Then, any two of the parts can be respectively regarded as the first part 341 and the second part 342 mentioned above, so that the nutrition pump can be adapted to more types of infusion pipeline assemblies 700, and the embodiment of the present application is not limited to this.

[0131] In some embodiments, the first contour line and the second contour line may differ in only one of shape and curvature, or the first portion 341 and the second portion 342 may differ in both shape and curvature, which is not limited in the present embodiment. Thus, at least two different portions are formed on the second side wall 34, so that the side wall of the clamping portion of different specifications can be selectively abutted against the first portion 341 or the second portion 342 according to the specific specifications of the infusion pipeline assembly 700.

[0132] Below, the structure of the infusion pipeline assembly 700 and the infusion principle are explained as a whole. The infusion pipeline assembly 700 may include a first pipeline 71, a pipeline connector 72, and a second pipeline 73 that are connected in sequence. During use, the inlet end of the first pipeline 71 is used to communicate with a liquid container such as an infusion bag. The outlet end of the second pipeline 73 is used to inject nutrient solution into the patient's body. For example, the middle part of the second pipeline 73 is installed to the extrusion component 200 of the nutrient pump, and the extrusion component 200 squeezes the second pipeline 73 so that the liquid in the second pipeline 73 moves forward to be injected into the patient's body, thereby realizing the function of driving the liquid in the infusion pipeline assembly 700 to flow in a preset direction.

[0133] Generally, different specifications of the infusion pipeline assembly 700 will connect one or more first pipelines 71 with the second pipeline 73 through different types of pipeline connectors 72. Then, in the embodiment of the present application, the pipeline connectors 72 of the infusion pipeline assembly 700 of different specifications can be used as the clamping part, or the first part 341 and the second part 342 are respectively used to abut against different types of pipeline connectors 72 in the infusion pipeline assembly 700, so that the space formed between the second side wall 34 and the support surface 32 can clamp at least two different specifications of the infusion pipeline assembly 700.

[0134] Exemplarily, the engaging portion may include a drip pot 72a, and the first portion 341 is used for engaging the drip pot 72a.

[0135] Specifically, the drip pot 72a is also called the intravenous drip pot 72a, which has the function of discharging the gas in the lumen before infusion and monitoring the dripping speed of the infusion, and can also be used to add drugs, etc. Therefore, by clamping and fixing the drip pot 72a with the first part 341, the gas in the infusion pipeline assembly 700 can be discharged more stably, and it is convenient to detect the dripping speed of the infusion.

[0136] In addition, in the infusion pipeline assembly 700, the first pipe 71 and the second pipe 73 are usually deformable to a certain extent. Therefore, if a certain part of the first pipe 71 is used as the clamping part, when the extrusion component 200 squeezes the second pipe 73, the first pipe 71 and the second pipe 73 are easily deformed, thereby affecting the infusion accuracy of the extrusion component 200. In contrast, the drip pot 72a is usually hard, so by clamping and fixing the drip pot 72a, the influence of the deformation of the first pipe 71 on the injection accuracy of the extrusion component 200 can be further avoided.

[0137] The first portion 341 may include a plurality of first sub-portions 3411. The plurality of first sub-portions 3411 are disposed along the circumference of the first through hole 31, and the plurality of first sub-portions 3411 are coaxially disposed.

[0138] Furthermore, a plurality of first sub-portions 3411 may be arranged to form a space for receiving the drip pot 72a.

[0139] Thus, multiple first sub-portions 3411 can press against the dripping pot 72a from different positions on the outer peripheral side of the dripping pot 72a to limit the radial movement of the dripping pot 72a along the first through hole 31; at the same time, the extrusion component 200 is cooperated to pull the second pipe 73, and the support surface 32 limits the movement of the dripping pot 72a in the direction close to the extrusion component 200, so as to achieve multi-dimensional fixation of the dripping pot 72a.

[0140] Exemplarily, a first notch 35 is provided on the inner wall of the first through hole 31 on the side facing away from the shell 100, so that the infusion tube assembly 700 can enter or leave the first through hole 31 from the first notch 35, thereby facilitating the user to directly hang the infusion tube assembly 700 into the first through hole 31 for clamping.

[0141] Correspondingly, a first sub-portion 3411 may be provided at both opening ends of the first notch 35; at least one first sub-portion 3411 is located on the side of the second side wall 34 facing the first notch 35. Thus, the three first sub-portions 3411 respectively support the drip pot 72a from three positions on the circumference of the drip pot 72a to completely restrict the radial movement of the drip pot 72a along the first through hole 31.

[0142] In some embodiments, the clamping portion may further include a three-way connector 72b, and the second portion 342 is used to clamp the three-way connector 72b.

[0143] Specifically, the three-way joint 72b is a joint including two liquid inlets and one liquid outlet. The liquid outlet of the three-way joint 72b is connected to the inlet of the second pipeline 73. The two liquid inlets of the three-way joint 72b are respectively connected to different first pipelines 71, so that different first pipelines 71 can be connected to different liquid containers, so that the three-way connection can inject two target liquids into the second pipeline 73, and the extrusion component 200 injects the target liquid in the second pipeline 73 into the patient's body.

[0144] It is understandable that in the infusion pipeline assembly 700, the first pipe 71 and the second pipe 73 are usually deformable to a certain extent. Then, if a certain part of the first pipe 71 is used as the clamping part, in the process of squeezing the second pipe 73 by the squeezing component 200, the first pipe 71 and the second pipe 73 are easily deformed, thereby affecting the infusion accuracy of the squeezing component 200. In contrast, the drip pot 72a is usually hard, so by clamping and fixing the drip pot 72a, it can further avoid the influence of the deformation of the first pipe 71 on the injection accuracy of the squeezing component 200.

[0145] In some embodiments, the second portion 342 may include two second sub-portions 3421 . The two second sub-portions 3421 are symmetrically arranged about the axis of the first through hole 31 .

[0146] Exemplarily, the second portion 342 may include two second sub-portions 3421. The two second sub-portions 3421 are arranged opposite to each other, and both of the two second sub-portions 3421 are arc-shaped and the axis lines of the two second sub-portions 3421 do not overlap, so that the space formed by the two second sub-portions 3421 can be clamped with the three-way connector 72b of the infusion pipeline assembly 700.

[0147] Of course, the second part 342 may include two second subparts 3421. The two second subparts 3421 are arranged opposite to each other, and both of the two second subparts 3421 are rectangular, so that the space formed by the two second subparts 3421 can be clamped with the three-way connector 72b of the infusion pipeline assembly 700.

[0148] It is understandable that, depending on the shape of the three-way connector 72b, the specific structure of the second portion 342 may be varied, and this embodiment of the present application does not limit this.

[0149] In some embodiments, the housing sidewall provided with the first fixing member 300 includes a first surface 11. The two second sub-portions 3421 are respectively located on different sides of the first through hole 31 along the first direction H1. The first direction H1 is parallel to the first surface 11, and the first direction H1 is perpendicular to the direction of the first through hole 31 toward the extrusion member 200. The two inlets of the three-way joint 72b are arranged along the width direction of the three-way joint 72b, and each second sub-portion 3421 is used to clamp one end of the three-way joint 72b along the width direction.

[0150] Then, after the three-way connector 72b is snapped into the first through hole 31, the corresponding two first pipes 71 can be arranged in a direction parallel to the surface of the shell 100, so that the two first pipes 71 can be routed along the surface of the shell 100, thereby facilitating the subsequent snap-on fixation of the two first pipes 71.

[0151] It can also be understood that, in the first fixing component 300, the space formed by the first portion 341 and the supporting surface 32 may be used to clamp the drip pot 72a, and the space formed by the second portion 342 and the supporting surface 32 may not be used to clamp the three-way joint 72b; or the space formed by the first portion 341 and the supporting surface 32 may not be used to clamp the drip pot 72a, and the space formed by the second portion 342 and the supporting surface 32 may be used to clamp the three-way joint 72b; or the space formed by the first portion 341 and the supporting surface 32 may be used to clamp the drip pot 72a, and the space formed by the second portion 342 and the supporting surface 32 may be used to clamp the three-way joint 72b. The embodiment of the present application does not limit this.

[0152] In some embodiments, the first fixing member 300 may be integrally formed with the housing 100 .

[0153] Optionally, the first fixing component 300 may also be detachably mounted on the housing 100; for example, the first fixing component 300 is snap-connected, screw-connected, or magnetically connected to the housing 100, which is not limited in the embodiment of the present application.

[0154] In some embodiments, the nutrient pump may also include at least one of a pipeline control component 400, a first motor, a second motor, a first sensor, a clip-on structure 13 and a second fixing component 600. The specific structures of the pipeline control component 400, the first motor, the first sensor, the clip-on structure 13 and the second fixing component 600 can be respectively referred to the installation structure of the above-mentioned pipeline control component 400, the first motor, the second motor, the first sensor, the clip-on structure 13 and the second fixing component 600 relative to the above-mentioned first fixing component 300, and the embodiments of the present application will not be repeated here.

[0155] In some embodiments, the specific structure of the extrusion component 200 can refer to the above-mentioned extrusion component 200, and the embodiments of the present application will not be described in detail here.

[0156] Please continue to refer to Figure 7 The embodiment of the present application also provides a nutrition pump, including a shell 100, an extrusion component 200, a first fixing component 300 and a pipeline control component 400. The extrusion component 200 is used to extrude the infusion pipeline assembly 700 so that the liquid in the infusion pipeline assembly 700 flows along a preset direction. The first fixing component 300 is arranged on the shell 100. The first fixing component 300 is provided with a first through hole 31, and the first through hole 31 can at least place the three-way connector 72b of the infusion pipeline assembly 700. The pipeline control component 400 is used to control the on-off of different pipelines connected to the three-way connector 72b. Among them, the extrusion component 200, the first fixing component 300 and the pipeline control component 400 are arranged on the same shell side wall of the shell 100, and the pipeline control component 400 is located on the side of the first through hole 31 away from the extrusion component 200, and there is no overlapping area between the pipeline control component 400 and the inner wall of the first through hole 31 in the orthographic projection on the bottom surface of the nutrition pump.

[0157] Therefore, after the clamping part of the infusion pipeline assembly 700 is clamped into the first through hole 31, the pipeline control component 400 can avoid the clamping part to prevent the pipeline control component 400 from affecting the disassembly and assembly of the clamping part.

[0158] In some embodiments, the inner wall of the first through hole 31 is used to place at least two different specifications of the clamping parts of the infusion pipeline assembly 700, and the two different specifications of the clamping parts of the infusion pipeline assembly 700 include a three-way connector 72b and a drip pot 72a.

[0159] In some implementations, the specific structure of the first fixing component 300 can refer to the first fixing component 300 described above, and the embodiments of the present application are not limited to this.

[0160] In some embodiments, the abutment portion of the inner wall of the first through hole 31 may include a first part 341 and / or a second part 342. The specific structures of the first part 341 and the second part 342 can refer to the above-mentioned first part 341 and the second part 342, respectively, and the embodiments of the present application are not limited here.

[0161] In some embodiments, the nutrient pump may also include at least one of a pipeline control component 400, a first motor, a second motor, a first sensor, a clip-on structure 13, and a second fixing component 600. The specific structures of the pipeline control component 400, the first motor, the first sensor, the clip-on structure 13, and the second fixing component 600 may refer to the above-mentioned pipeline control component 400, the first motor, the second motor, the first sensor, the clip-on structure 13, and the second fixing component 600, respectively, and the embodiments of the present application will not be described in detail herein.

[0162] In some embodiments, the specific structure of the extrusion component 200 can refer to the above-mentioned extrusion component 200, and the embodiments of the present application will not be described in detail here.

[0163] Please continue to refer to Figure 7 and Figure 8 The embodiment of the present application also provides a nutrition pump, including a shell 100, an extrusion component 200, a first fixing component 300 and a pipeline control component 400.

[0164] The extrusion component 200 is disposed on the housing 100, and the extrusion component 200 is used to drive the liquid in the infusion pipeline assembly 700 to flow along a preset direction. The first fixing component 300 is disposed on the housing 100. The first fixing component 300 is provided with a first through hole 31, and one end of the first through hole 31 faces the extrusion component 200. The inner wall of the first through hole 31 includes a support surface 32, a first side wall 33 and a second side wall 34. The support surface 32 is used to support the clamping part of the infusion pipeline assembly 700 to limit the clamping part from moving in a direction close to the extrusion component 200. The end of the first side wall 33 facing away from the extrusion component 200 is connected to the support surface 32, and the end of the second side wall 34 facing the extrusion component 200 is connected to the support surface 32. The first part 341 and the second part 342 are arranged along the circumference of the first through hole 31, and the shape and / or curvature of the first part 341 is different from the shape and / or curvature of the second part 342. The space formed between the second side wall 34 and the support surface 32 is capable of accommodating at least two different sizes of the clamping parts of the infusion pipeline assembly 700, and the clamping parts include a three-way connector 72b or a drip pot 72a. The pipeline control component 400 is used to control the on-off of different pipelines in the infusion pipeline assembly 700. The extrusion component 200, the first fixing component 300 and the pipeline control component 400 are arranged on the same shell side wall of the shell 100, and the pipeline control component 400 is located on the side of the first fixing component 300 away from the extrusion component 200. There is no overlap between the support surface 32 and the pipeline control component 400 in the bottom surface of the nutrition pump.

[0165] Then, when the nutrition pump is actually working, the support surface 32 is used for limiting, so that the accurate position of the infusion line assembly 700 in the length direction can be ensured to be clamped on the first fixing component 300, thereby ensuring that the extrusion component 200 can squeeze the accurate position of the infusion line assembly 700, and finally ensuring the infusion accuracy of the nutrition pump. At the same time, different types of infusion line assemblies 700 can be placed through the first part 341 and the second part 342 of the second side wall 34, so that the nutrition pump can adapt to more infusion line assemblies 700 of different specifications. It can be seen that the nutrition pump of the embodiment of the present application has the advantage of good general performance on the basis of meeting the actual demand for infusion accuracy.

[0166] Furthermore, taking the example that one of the first part 341 and the second part 342 is used to place the drip pot 72a and the other is used to place the three-way connector 72b, it can avoid the pipeline control component 400 from interfering with the end of the drip pot 72a that is away from the extrusion component 200. Finally, on the basis of setting the pipeline control component 400 for the nutrition pump, the first fixing component 300 can also be compatible with the infusion pipeline assembly 700 with the drip pot 72a.

[0167] On the other hand, when the three-way connector 72b is connected to the first fixing component 300, the two first pipes 71 can be switched on and off by the pipeline control component 400. For example, the first first pipe 71 is used to transport nutrient solution, and the second pipe is used to transport cleaning solution. The first pipe and the second pipe can be controlled to infuse solution in different time periods by the control component, so that the nutrient pump has two functions: cleaning and infusing nutrient solution.

[0168] In some embodiments, the specific structures of the extrusion component 200, the first fixing component 300 and the pipeline control component 400 can refer to the above-mentioned extrusion component 200, the first fixing component 300 and the pipeline control component 400 respectively, and the embodiments of the present application are not repeated here.

[0169] In some embodiments, the nutrient pump may further include a first motor, a second motor, a first sensor, a snap-on structure 13, and a second fixing component 600, etc. The specific structures of the first motor, the first sensor, the snap-on structure 13, and the second fixing component 600 may refer to the above-mentioned first motor, the second motor, the first sensor, the snap-on structure 13, and the second fixing component 600, respectively, and the embodiments of the present application will not be described in detail herein.

[0170] Please continue to refer to Figure 1The embodiment of the present application also provides a medical infusion pump, including a housing 100 and a first fixing component 300. The first fixing component 300 is disposed on the housing 100. The first fixing component 300 is provided with a first through hole 31, and the first through hole 31 can be used to place at least two different types of pipe connectors 72 of the infusion pipeline assembly 700, and the pipe connector 72 that can be placed in the first through hole 31 includes at least a drip pot 72a. Thus, the medical infusion pump can be adapted to more types of infusion pipeline assemblies 700 to improve the versatility of the medical infusion pump.

[0171] In some embodiments, the pipe connector 72 in which the first through hole 31 can be placed further includes a three-way connector 72b.

[0172] In some implementations, the specific structure of the first fixing component 300 may refer to the first fixing component 300 of the nutrition pump described above, and the embodiments of the present application do not limit this.

[0173] In some embodiments, the medical infusion pump may also include a pipeline control component 400, a first motor, a second motor, a first sensor, a clip-on structure 13, and a second fixing component 600, etc. The specific structures of the pipeline control component 400, the first motor, the first sensor, the clip-on structure 13, and the second fixing component 600 can be respectively referred to the pipeline control component 400, the first motor, the second motor, the first sensor, the clip-on structure 13, and the second fixing component 600 of the above-mentioned nutrition pump, and the embodiments of the present application will not be repeated here.

[0174] Please continue to refer to Figure 1 The embodiment of the present application also provides a fixing component of an infusion line assembly, which is applied to a nutrition pump. The fixing component of the infusion line assembly is provided with a first through hole 31, and the inner wall of the first through hole 31 includes a support surface 32, a first side wall 33 and a second side wall 34. The support surface 32 is used to support the clamping part of the infusion line assembly 700 to limit the clamping part from moving toward the first side in the axial direction of the first through hole 31. The end of the first side wall 33 away from the first side is connected to the support surface 32. The end of the second side wall 34 close to the first side is connected to the support surface 32. The second side wall 34 includes a first part 341 and a second part 342, and the first part 341 and the second part are both connected to the support surface 32. And the curvature and / or shape of the first part 341 is different from the curvature and / or shape of the second part 342, so that the space formed between the second side wall 34 and the support surface 32 can accommodate at least two different specifications of the clamping parts of the infusion line assembly 700.

[0175] Then, after the infusion line assembly fixing component is installed to the nutrition pump, the first through hole 31 can be facing the extrusion component 200 of the nutrition pump, and the support surface 32 is located on the side of the first side wall 33 away from the extrusion component 200. Therefore, when the nutrition pump is actually working, the support surface 32 is limited to ensure that the accurate position of the infusion line assembly 700 in the length direction is fixed on the first fixing component 300, thereby ensuring that the extrusion component 200 can squeeze the accurate position of the infusion line assembly 700, and finally ensure the infusion accuracy of the nutrition pump. At the same time, different types of infusion line assemblies 700 can also be clamped by the first part 341 and the second part 342 of the second side wall 34, so that the nutrition pump can adapt to more different specifications of infusion line assemblies 700. It can be seen that the nutrition pump of the embodiment of the present application has the advantage of good general performance on the basis of meeting the actual demand of infusion accuracy.

[0176] It can also be understood that the second side wall 34 can also include at least three, such as three, four, five or six different parts, and the different parts are respectively used to adapt to the clamping parts of the infusion pipeline assembly 700 of different specifications. Then, any two of the parts can be respectively regarded as the first part 341 and the second part 342 mentioned above, so that the nutrition pump can adapt to more types of infusion pipeline assemblies 700, which is not limited in the embodiment of the present application.

[0177] In some embodiments, at least one of the shape and curvature of the first part 341 and the second part 342 is different. The first part 341 and the second part 342 may be different in only one of the shape and curvature, or the first part 341 and the second part 342 may be different in both shape and curvature, which is not limited in the present embodiment. Thus, at least two different parts are formed on the second side wall 34, so that the side wall of the clamping part of different specifications can be selectively abutted against the first part 341 or the second part 342 according to the specific specifications of the infusion pipeline assembly 700.

[0178] In some embodiments, the side of the first portion 341 away from the first side may have a first contour line, and the side of the second portion 342 away from the first side may have a second contour line, and the curvature and / or shape of the first contour line is different from the curvature and / or shape of the second contour line.

[0179] For example, the first fixing component 300 has an upper surface facing away from the first side, and the contour line of the first portion 341 at the upper surface, ie, the first contour line, and the contour line of the second portion at the upper surface, ie, the second contour line, have different curvatures and / or shapes.

[0180] Below, the structure of the infusion pipeline assembly 700 and the infusion principle are explained as a whole. The infusion pipeline assembly 700 may include a first pipeline 71, a pipeline connector 72, and a second pipeline 73 that are connected in sequence. During use, the inlet end of the first pipeline 71 is used to communicate with a liquid container such as an infusion bag. The outlet section of the second pipeline 73 is used to inject nutrient solution into the patient's body. For example, the second pipeline 73 is installed to the extrusion component 200 of the nutrient pump, and the extrusion component 200 squeezes the second pipeline 73 so that the liquid in the second pipeline 73 moves forward to be injected into the patient's body, thereby realizing the function of driving the liquid in the infusion pipeline assembly 700 to flow in a preset direction.

[0181] Generally, different specifications of the infusion pipeline assembly 700 will connect one or more first pipelines 71 with the second pipeline 73 through different types of pipeline connectors 72. Then, in the embodiment of the present application, the pipeline connectors 72 of the infusion pipeline assembly 700 of different specifications can be used as the clamping part, or the first part 341 and the second part 342 are respectively used to abut against different types of pipeline connectors 72 in the infusion pipeline assembly 700, so that the space formed between the second side wall 34 and the support surface 32 can accommodate at least two different specifications of the clamping parts of the infusion pipeline assembly 700.

[0182] Exemplarily, the clamping portion may include a drip pot 72 a , and the space enclosed by the first portion 341 and the supporting surface 32 is used to place the drip pot 72 a .

[0183] Specifically, the drip pot 72a is also called the intravenous drip pot 72a, which has the function of discharging the gas in the lumen before infusion and monitoring the dripping speed of the infusion, and can also be used to add drugs, etc. Therefore, by clamping and fixing the drip pot 72a with the first part 341, the gas in the infusion pipeline assembly 700 can be discharged more stably, and it is convenient to detect the dripping speed of the infusion.

[0184] In addition, in the infusion pipeline assembly 700, the first pipe 71 and the second pipe 73 are usually deformable to a certain extent. Therefore, if a certain part of the first pipe 71 is used as the clamping part, when the extrusion component 200 extrudes the second pipe 73, the first pipe 71 and the second pipe 73 are easily deformed, thereby affecting the infusion accuracy of the extrusion component 200. In contrast, the drip pot 72a is usually hard, so fixing the drip pot 72a can further avoid the influence of the deformation of the first pipe 71 on the injection accuracy of the extrusion component 200.

[0185] The first portion 341 may include a plurality of first sub-portions 3411. The plurality of first sub-portions 3411 are disposed along the circumference of the first through hole 31, and the plurality of first sub-portions 3411 are coaxially disposed.

[0186] Furthermore, the plurality of first sub-portions 3411 can be arranged to form a space for clamping the drip pot 72a. Thus, the plurality of first sub-portions 3411 can press against the drip pot 72a from different positions on the outer circumference of the drip pot 72a to limit the radial movement of the drip pot 72a along the first through hole 31; at the same time, the extrusion component 200 pulls the second pipe 73, and the support surface 32 limits the movement of the drip pot 72a in the direction close to the extrusion component 200, so that the drip pot 72a can be fixed in multiple dimensions.

[0187] Illustratively, a first notch 35 is provided on one side of the inner wall of the first through hole 31 so that the infusion line assembly 700 can enter or leave the first through hole 31 from the first notch 35, thereby facilitating the user to directly hang the infusion line assembly 700 into the first through hole 31 for clamping.

[0188] In some embodiments, the side of the infusion tube assembly fixing component facing away from the first notch 35 is used to connect with the housing 100 of the nutrition pump, so as to facilitate the removal and placement of the infusion tube assembly 700.

[0189] Correspondingly, a first sub-portion 3411 may be provided at both sides of the opening edge of the first notch 35; at least one first sub-portion 3411 is located on the side of the second side wall 34 facing the first notch 35. Thus, the three first sub-portions 3411 respectively block the drip pot 72a from three positions in the circumferential direction of the drip pot 72a to completely restrict the radial movement of the drip pot 72a along the first through hole 31.

[0190] In some embodiments, the clamping portion includes a three-way connector 72 b , and a space enclosed by the second portion 342 and the supporting surface 32 is used to place the three-way connector 72 b .

[0191] Specifically, the three-way joint 72b is a joint including two liquid inlets and one liquid outlet. The liquid outlet of the three-way joint 72b is connected to the inlet of the second pipeline 73. The two liquid inlets of the three-way joint 72b are respectively connected to different first pipelines 71, so that different first pipelines 71 can be connected to different liquid containers, so that the three-way connection can inject two target liquids into the second pipeline 73, and the extrusion component 200 injects the target liquid in the second pipeline 73 into the patient's body.

[0192] It is understandable that in the infusion pipeline assembly 700, the first pipe 71 and the second pipe 73 are usually deformable to a certain extent. Then, if a certain part of the first pipe 71 is used as the clamping part, in the process of squeezing the second pipe 73 by the squeezing component 200, the first pipe 71 and the second pipe 73 are easily deformed, thereby affecting the infusion accuracy of the squeezing component 200. In contrast, the drip pot 72a is usually hard, so fixing the drip pot 72a can further avoid the influence of the deformation of the first pipe 71 on the injection accuracy of the squeezing component 200.

[0193] In some embodiments, the second portion 342 may include two second sub-portions 3421 . The two second sub-portions 3421 are symmetrically arranged about the axis of the first through hole 31 .

[0194] Exemplarily, the second portion 342 may include two second sub-portions 3421. The two second sub-portions 3421 are arranged opposite to each other, and both of the two second sub-portions 3421 are arc-shaped and the axis lines of the two second sub-portions 3421 do not overlap, so that the space formed by the two second sub-portions 3421 can be clamped with the three-way connector 72b of the infusion pipeline assembly 700.

[0195] Of course, the second part 342 may include two second subparts 3421. The two second subparts 3421 are arranged opposite to each other, and both of the two second subparts 3421 are rectangular, so that the space formed by the two second subparts 3421 can be clamped with the three-way connector 72b of the infusion pipeline assembly 700.

[0196] It is understandable that, depending on the shape of the three-way connector 72b, the specific structure of the second portion 342 may be varied, and this embodiment of the present application does not limit this.

[0197] In some embodiments, the two second sub-portions 3421 are respectively located on different sides of the first notch 35. The two inlets of the three-way connector 72b are arranged along the width direction of the three-way connector 72b, and each second sub-portion 3421 is used to clamp one end of the three-way connector 72b along the width direction.

[0198] Then, in combination with the above-mentioned infusion pipeline assembly fixing component, the side away from the first notch 35 is used to connect with the shell 100 of the nutrition pump. After the three-way connector 72b is snapped into the first through hole 31, the corresponding two first pipes 71 can be arranged in a direction parallel to the surface of the shell 100, so that the two first pipes 71 can be routed along the surface of the shell 100, thereby facilitating the subsequent snap-on fixation of the two first pipes 71.

[0199] It can also be understood that the space formed by the first part 341 and the supporting surface 32 can be used to place the dripping pot 72a, and the space formed by the second part 342 and the supporting surface 32 can not be used to place the three-way joint 72b; or the space formed by the first part 341 and the supporting surface 32 can not be used to place the dripping pot 72a, and the space formed by the second part 342 and the supporting surface 32 can be used to place the three-way joint 72b; or the space formed by the first part 341 and the supporting surface 32 can be used to place the dripping pot 72a, and the space formed by the second part 342 and the supporting surface 32 can be used to place the three-way joint 72b. The embodiment of the present application does not limit this.

[0200] In some embodiments, the support surface 32 may be a flat plane, or a curved surface, or may be formed by splicing two, three or even four surfaces, which is not limited in the embodiments of the present application.

[0201] For example, the support surface 32 may include a first support surface 321 and a second support surface 322. The first support surface 321 is connected to the first portion 341 and the first side wall 33, respectively. The second support surface 322 is connected to the second portion 342 and the first side wall 33, respectively. The first support surface 321 and the second support surface 322 are offset from each other in the axial direction of the first through hole 31.

[0202] Please continue to refer to Fig.11 The embodiment of the present application also provides a fixing component of an infusion line assembly, which is applied to a nutrition pump. The fixing component of the infusion line assembly includes an upper surface and a first through hole 31 with one end opening located on the upper surface. The inner wall of the first through hole 31 includes a first part 341 and a second part 342. The first part 341 and the second part 342 are arranged along the circumference of the first through hole 31, and the contour line of the first part 341 at the upper surface and the contour line of the second part 342 at the upper surface have different curvatures and / or shapes. Along the same direction of the axis of the first through hole 31, the first part 341 and the second part 342 are inclined toward the axis direction close to the first through hole 31, and the first part 341 and the second part 342 are respectively used to abut against the clamping parts of the infusion line assemblies 700 of different specifications, so that the space enclosed by the first part 341 and the second part 342 can clamp the clamping parts of at least two different specifications of the infusion line assemblies 700.

[0203] Then, after the infusion line assembly fixing component is installed on the nutrition pump, the first through hole 31 can face the extrusion component 200 of the nutrition pump, and the end of the first part 341 with a smaller inner diameter is relatively close to the extrusion component 200. Therefore, when the nutrition pump is working, the extrusion component 200 can exert a force on the infusion line assembly 700 to pull the clamping part toward the extrusion component 200. At this time, the inclined first part 341 or the second part 342 can limit the movement of the clamping part toward the extrusion component 200, and can also limit the radial movement of the clamping part along the first through hole 31, so as to ensure that the accurate position of the infusion line assembly 700 in the length direction is clamped on the infusion line assembly fixing component, thereby ensuring that the extrusion component 200 can squeeze the accurate position of the infusion line assembly 700, and finally ensure the infusion accuracy of the nutrition pump. Furthermore, the nutrition pump can also be connected to different types of infusion line assemblies 700 through the first part 341 and the second part 342, so that the nutrition pump can be adapted to more different specifications of infusion line assemblies 700. It can be seen that the nutrition pump of the embodiment of the present application has the advantage of good universal performance on the basis of meeting the actual requirements of infusion accuracy.

[0204] It can also be understood that the inner wall of the first through hole 31 can also include at least three, such as three, four, five or six different parts, and the different parts are respectively used to abut against the clamping parts of the infusion pipeline assembly 700 of different specifications. Then, any two of the parts can be respectively regarded as the first part 341 and the second part 342 mentioned above, so that the nutrition pump can be adapted to more types of infusion pipeline assemblies 700, and the embodiment of the present application is not limited to this.

[0205] In some embodiments, the contour line of the first part 341 on the upper surface is different from the contour line of the second part 342 on the upper surface in curvature and / or shape. The contour line of the first part 341 on the upper surface is different from the contour line of the second part 342 on the upper surface in only one of the curvature and shape, or the contour line of the first part 341 on the upper surface is different from the contour line of the second part 342 on the upper surface in both curvature and shape. The embodiment of the present application does not limit this. Thus, at least two different parts are formed on the second side wall 34, so that according to the specific specifications of the infusion pipeline assembly 700, the side wall of the clamping part of different specifications can be selectively abutted to the first part 341 or the second part 342.

[0206] Below, the structure of the infusion pipeline assembly 700 and the infusion principle are explained as a whole. The infusion pipeline assembly 700 may include a first pipeline 71, a pipeline connector 72, and a second pipeline 73 that are connected in sequence. During use, the inlet end of the first pipeline 71 is used to communicate with a liquid container such as an infusion bag. The outlet section of the second pipeline 73 is used to inject nutrient solution into the patient's body. For example, the second pipeline 73 is installed to the extrusion component 200 of the nutrient pump, and the extrusion component 200 squeezes the second pipeline 73 so that the liquid in the second pipeline 73 moves forward to be injected into the patient's body, thereby realizing the function of driving the liquid in the infusion pipeline assembly 700 to flow in a preset direction.

[0207] Generally, different specifications of the infusion pipeline assembly 700 will connect one or more first pipelines 71 with the second pipeline 73 through different types of pipeline connectors 72. Then, in the embodiment of the present application, the pipeline connectors 72 of the infusion pipeline assembly 700 of different specifications can be used as the clamping part, or the first part 341 and the second part 342 are respectively used to abut against different types of pipeline connectors 72 in the infusion pipeline assembly 700, so that the space formed between the second side wall 34 and the support surface 32 can clamp at least two different specifications of the infusion pipeline assembly 700.

[0208] Exemplarily, the engaging portion may include a drip pot 72a, and the first portion 341 is used for engaging the drip pot 72a.

[0209] Specifically, the drip pot 72a is also called the intravenous drip pot 72a, which has the function of discharging the gas in the lumen before infusion and monitoring the dripping speed of the infusion, and can also be used to add drugs, etc. Therefore, by fixing the drip pot 72a by the first part 341, the gas in the infusion pipeline assembly 700 can be discharged more stably, and it is convenient to detect the dripping speed of the infusion.

[0210] In addition, in the infusion pipeline assembly 700, the first pipe 71 and the second pipe 73 are usually deformable to a certain extent. Therefore, if a certain part of the first pipe 71 is used as the clamping part, during the process of squeezing the second pipe 73 by the squeezing component 200, the first pipe 71 and the second pipe 73 are easily deformed, thereby affecting the infusion accuracy of the squeezing component 200. In contrast, the drip pot 72a is usually hard, so by clamping and fixing the drip pot 72a, the influence of the deformation of the first pipe 71 on the injection accuracy of the squeezing component 200 can be further avoided.

[0211] The first portion 341 may include a plurality of first sub-portions 3411. The plurality of first sub-portions 3411 are disposed along the circumference of the first through hole 31, and the plurality of first sub-portions 3411 are coaxially disposed.

[0212] Furthermore, a plurality of first sub-portions 3411 may be arranged to form a space for receiving the drip pot 72a.

[0213] Thus, multiple first sub-portions 3411 can press against the dripping pot 72a from different positions on the outer peripheral side of the dripping pot 72a to limit the radial movement of the dripping pot 72a along the first through hole 31; at the same time, the extrusion component 200 is cooperated to pull the second pipe 73, and the support surface 32 limits the movement of the dripping pot 72a in the direction close to the extrusion component 200, so as to achieve multi-dimensional fixation of the dripping pot 72a.

[0214] Illustratively, a first notch 35 is provided on one side of the inner wall of the first through hole 31 so that the infusion line assembly 700 can enter or leave the first through hole 31 from the first notch 35, thereby facilitating the user to directly hang the infusion line assembly 700 into the first through hole 31 for clamping.

[0215] In some embodiments, the side of the infusion tube assembly fixing component facing away from the first notch 35 is used to connect with the housing 100 of the nutrition pump, so as to facilitate the removal and placement of the infusion tube assembly 700.

[0216] Correspondingly, a first sub-portion 3411 may be provided at both opening ends of the first notch 35; at least one first sub-portion 3411 is located on the side of the second side wall 34 facing the first notch 35. Thus, the three first sub-portions 3411 respectively support the drip pot 72a from three positions on the circumference of the drip pot 72a to completely restrict the radial movement of the drip pot 72a along the first through hole 31.

[0217] In some embodiments, the clamping portion includes a three-way connector 72 b , and a space enclosed by the second portion 342 and the support surface 32 is used for clamping the three-way connector 72 b .

[0218] In some embodiments, the clamping portion includes a three-way connector 72 b , and a space enclosed by the second portion 342 and the support surface 32 is used for clamping the three-way connector 72 b .

[0219] Specifically, the three-way joint 72b is a joint including two liquid inlets and one liquid outlet. The liquid outlet of the three-way joint 72b is connected to the inlet of the second pipeline 73. The two liquid inlets of the three-way joint 72b are respectively connected to different first pipelines 71, so that different first pipelines 71 can be connected to different liquid containers, so that the three-way connection can inject two target liquids into the second pipeline 73, and the extrusion component 200 injects the target liquid in the second pipeline 73 into the patient's body.

[0220] It is understandable that in the infusion pipeline assembly 700, the first pipe 71 and the second pipe 73 are usually deformable to a certain extent. Then, if a certain part of the first pipe 71 is used as the clamping part, in the process of squeezing the second pipe 73 by the squeezing component 200, the first pipe 71 and the second pipe 73 are easily deformed, thereby affecting the infusion accuracy of the squeezing component 200. In contrast, the drip pot 72a is usually hard, so by clamping and fixing the drip pot 72a, it can further avoid the influence of the deformation of the first pipe 71 on the injection accuracy of the squeezing component 200.

[0221] In some embodiments, the second portion 342 may include two second sub-portions 3421. The two second sub-portions 3421 are symmetrically arranged about the axis of the first through hole 31 to be used for clamping different ends of the three-way connector 72b in the width direction.

[0222] Exemplarily, the second portion 342 may include two second sub-portions 3421. The two second sub-portions 3421 are arranged opposite to each other, and both of the two second sub-portions 3421 are arc-shaped and the axis lines of the two second sub-portions 3421 do not overlap, so that the space formed by the two second sub-portions 3421 can be clamped with the three-way connector 72b of the infusion pipeline assembly 700.

[0223] Of course, the second part 342 may include two second subparts 3421. The two second subparts 3421 are arranged opposite to each other, and both of the two second subparts 3421 are rectangular, so that the space formed by the two second subparts 3421 can be clamped with the three-way connector 72b of the infusion pipeline assembly 700.

[0224] It is understandable that, depending on the shape of the three-way connector 72b, the specific structure of the second portion 342 may be varied, and this embodiment of the present application does not limit this.

[0225] In some embodiments, the two second sub-portions 3421 are respectively located on different sides of the first notch 35. The two inlets of the three-way connector 72b are arranged along the width direction of the three-way connector 72b, and each second sub-portion 3421 is used to clamp one end of the three-way connector 72b along the width direction.

[0226] Then, in combination with the above-mentioned infusion pipeline assembly fixing component, the side away from the first notch 35 is used to connect with the shell 100 of the nutrition pump. After the three-way connector 72b is snapped into the first through hole 31, the corresponding two first pipes 71 can be arranged in a direction parallel to the surface of the shell 100, so that the two first pipes 71 can be routed along the surface of the shell 100, thereby facilitating the subsequent snap-on fixation of the two first pipes 71.

[0227] It can also be understood that the space formed by the first part 341 and the supporting surface 32 can be used to clamp the drip pot 72a, and the space formed by the second part 342 and the supporting surface 32 can be not used to clamp the three-way joint 72b; or the space formed by the first part 341 and the supporting surface 32 can be not used to clamp the drip pot 72a, and the space formed by the second part 342 and the supporting surface 32 can be used to clamp the three-way joint 72b; or the space formed by the first part 341 and the supporting surface 32 can be used to clamp the drip pot 72a, and the space formed by the second part 342 and the supporting surface 32 can be used to clamp the three-way joint 72b. The embodiment of the present application does not limit this.

[0228] In some embodiments, the support surface 32 may be a flat plane, or a curved surface, or may be formed by splicing two, three or even four surfaces, which is not limited in the embodiments of the present application.

[0229] For example, the support surface 32 may include a first support surface 321 and a second support surface 322. The first support surface 321 is connected to the first portion 341 and the first side wall 33, respectively. The second support surface 322 is connected to the second portion 342 and the first side wall 33, respectively. The first support surface 321 and the second support surface 322 are offset from each other in the axial direction of the first through hole 31.

[0230] Please continue to refer to Figure 1 The embodiment of the present application also provides an infusion line assembly fixing component, which is applied to a medical infusion pump. The infusion line assembly fixing component is provided with a first through hole 31. The first through hole 31 can be used to place at least two different types of pipe connectors 72 of the infusion line assembly 700, and the pipe connector 72 that can be placed in the first through hole 31 includes a drip pot 72a.

[0231] In some embodiments, the pipe connector 72 in which the first through hole 31 can be placed further includes a three-way connector 72b.
