Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to an infusion consumable, an infusion device and a method for detecting an infusion consumable model. Background Art

[0002] Liquid can be input into the patient through the nutrition pump to meet the needs of the patient. For example, the liquid can be a nutrition solution.

[0003] Usually, a nutrition pump can use multiple models of infusion consumables. After the infusion consumables are installed on the nutrition pump, the nutrition pump can automatically identify the specific model of the infusion consumables, and the infusion mode can be determined according to the model of the infusion consumables. In the related art, infusion consumables are divided into two categories, of which the first category includes two models of infusion consumables, namely, infusion consumables with identification parts and without identification parts. Nutrition pumps that match the first category of infusion consumables usually only need to set up one sensor to identify the above-mentioned identification parts. The second category includes multiple models of infusion consumables, and the types of identification parts set on each model of infusion consumables are different. Nutrition pumps that match the second category of infusion consumables usually need to set up multiple sensors, each sensor can identify one identification part, so this nutrition pump can identify multiple types of infusion consumables, and the identification type is related to the number of sensors.

[0004] However, there are fewer models of the first type of infusion consumables, which results in a smaller application range of nutrition pumps that match such infusion consumables. The second type of infusion consumables requires the nutrition pumps that match them to be equipped with multiple sensors, which results in a complex structure of the nutrition pumps and a higher cost. Summary of the invention

[0005] The purpose of the present invention is to provide an infusion consumable, an infusion device and a method for detecting an infusion consumable model. The infusion consumable has a simple structure and is easy to identify, which can solve the problem in the related art that the infusion device that cooperates with the infusion consumable has a complex structure and high cost due to the large number of sensors.

[0006] In a first aspect, the present application provides an infusion consumable for use in an infusion device, the infusion consumable comprising a mounting portion, the mounting portion being provided with a mounting hole, and an identification member being provided in the mounting hole, wherein the depth of the mounting hole is greater than or equal to the thickness of the identification member.

[0007] The infusion consumables in the embodiments of the present application can be provided with an identification piece so that the infusion device used in conjunction with the infusion consumable can identify the model of the infusion consumable, so as to select the infusion mode corresponding to the infusion consumable later. By providing a mounting hole on the mounting portion, a mounting position can be provided for the identification piece. In addition, the processing technology of the hole-shaped structure is relatively simple, which can reduce the processing cost of the infusion consumable. Among them, by setting the depth of the mounting hole to be greater than the thickness of the identification piece, different types of infusion consumables can be distinguished according to the depth of the identification piece in the mounting hole, thereby achieving the effect of using one identification piece to identify multiple types of infusion consumables. In this way, the structure of the infusion device corresponding to the infusion consumable can be simplified, thereby reducing the cost of the infusion device.

[0008] In a possible implementation manner, the identification element includes a magnetic element.

[0009] The infusion consumables in the embodiment of the present application can reduce the cost of the infusion consumables by providing the identification member with a structure including a magnetic member, because the cost of the magnetic member is relatively low. In addition, the magnetic member is magnetic and has polarity, so different identification parameters can be provided for distinguishing different infusion consumables, thereby providing the possibility of increasing the models of infusion consumables. In addition, identification parameters can also be provided for the identification of the infusion device, so that the infusion device can identify different infusion consumables.

[0010] In a possible implementation manner, the identification member is disposed at the bottom of the mounting hole.

[0011] By setting the identification piece at the bottom of the mounting hole, when the depth of the mounting hole is different, the distance from the top of the identification piece to the opening of the mounting hole can be different. This provides identification parameters for distinguishing different types of infusion consumables, such as the height information from the identification piece to the opening of the mounting hole or the magnetic flux information of the identification piece, so that the infusion device can identify infusion consumables with different signals.

[0012] In a possible implementation, a ratio of the depth of the mounting hole to the thickness of the identification element is greater than or equal to 2.

[0013] By setting the ratio of the depth of the mounting hole and the thickness of the identification piece to be greater than or equal to 2, the number of installation positions in the mounting hole of the identification piece can be increased. When the models of infusion consumables are distinguished by different installation positions, this makes it possible to increase the models of infusion consumables.

[0014] In a possible implementation, a limiting structure is provided in the mounting hole, and the limiting structure is used to limit the identification member to different heights in the mounting hole.

[0015] The infusion consumables in the embodiments of the present application can limit the identification piece to different heights of the mounting hole by setting a limiting structure in the mounting hole, and provide support for the identification piece to prevent the identification piece from shifting in the mounting hole, thereby ensuring that the infusion consumables can be used normally and extending the service life of the infusion consumables.

[0016] In a possible implementation manner, a plurality of the limiting structures are arranged at intervals along a depth direction of the mounting hole.

[0017] The infusion consumables in the embodiment of the present application are provided with a plurality of limiting structures, and the plurality of limiting structures are spaced apart along the depth direction of the mounting hole, so as to achieve setting the identification member at different heights in the mounting hole.

[0018] In a possible implementation, the infusion consumable further includes a fixing member, wherein the fixing member is disposed between the identification member and the mounting hole, and is used to fix the identification member to the mounting hole.

[0019] The infusion consumables in the embodiments of the present application can improve the stability of the connection between the identification piece and the mounting hole and extend the service life of the infusion consumables by providing a fixing piece.

[0020] In a possible implementation manner, the fixing element is glue or a sticky material.

[0021] The infusion consumables in the embodiment of the present application can reduce the difficulty of setting the fixing part by setting the fixing part as glue or sticky material. In other words, the fixing part formed by glue or sticky material can change with the shape of the identification part and the mounting hole, and fit the surface of the identification part and the mounting hole, which is convenient for setting. In addition, the fixing part formed by glue or sticky material can be a thinner layer, occupying a smaller volume, thereby reducing the influence of the fixing part on the identification part, thereby improving the accuracy of being identified when it is matched with the infusion device later.

[0022] Of course, in some embodiments, it is also possible not to set a limiting structure or a fixing member. For example, the mounting hole can be set as a gradual hole that gradually increases in size from the bottom to the top, and the identification member can be stably connected at the interference fit between the size and the mounting hole. In this way, the installation height of the identification member in the mounting hole can be changed by changing the inner diameter of the mounting hole. Of course, the identification member can also be connected to the mounting hole in other ways. In the embodiments of the present application, no further limitation is given.

[0023] In a possible implementation, there are a plurality of mounting holes, wherein the plurality of mounting holes are arranged at intervals on the mounting portion, and each mounting hole is configured to be provided with one identification member.

[0024] The infusion consumables in the embodiment of the present application are provided with a plurality of mounting holes, and each mounting hole is configured to be provided with an identification element. This can further increase the identification parameters for distinguishing different infusion consumables, thereby providing the possibility of increasing the models of infusion consumables. In addition, more identification parameters can be provided for the identification of the infusion device, so that the infusion device can identify different infusion consumables.

[0025] In a possible implementation, the infusion consumable further includes an infusion pipeline; wherein the infusion pipeline is fixedly connected to the mounting portion, and the mounting portion is used to connect the infusion consumable to a nutrition pump.

[0026] The infusion consumable in the embodiment of the present application is provided with an infusion pipeline so that the infusion consumable can be infused to the user.

[0027] The second aspect of the present application provides an infusion device, comprising a consumables installation slot and a consumables detection device. The consumables installation slot is configured to install any of the above-mentioned infusion consumables. The consumables detection device is arranged opposite to the identification piece on the infusion consumable to identify the model of the infusion consumable.

[0028] The infusion device in the embodiment of the present application is provided with a consumable installation slot so that the infusion consumable can be installed on the infusion device to ensure that the infusion consumable can be stably connected to the infusion device during use. The consumable detection device is provided to further identify the model of the infusion consumable installed on the infusion device so that the infusion device can determine the appropriate infusion mode according to the model of the infusion consumable.

[0029] In a possible implementation, the identification element of the infusion consumable includes a magnetic element. The consumable detection device includes:

[0030] A consumables detection component configured to obtain the magnetic field strength and / or direction of the identification component on the preset infusion consumables;

[0031] The controller is configured to determine the model of the preset infusion consumable according to the magnetic field strength and / or direction of the identification element.

[0032] The infusion device in the embodiment of the present application determines the model of the preset infusion consumables by setting the identification member to a structure including a magnetic member, and judging the model of the preset infusion consumables according to the magnetic field strength and / or direction of the identification member. Since the acquisition method and judgment method of the magnetic field strength and / or direction are relatively simple, this can simplify the identification process. In addition, there are many types of devices that can identify the magnetic field strength and / or direction, so the selection range of consumable detection parts can be expanded, which is conducive to the large-scale production of infusion equipment and can also provide a possibility for reducing the cost of the infusion equipment.

[0033] A third aspect of the present invention provides a method for detecting the model of an infusion consumable, which is applied to an infusion device. The infusion device is provided with a consumable mounting slot and a consumable detection device. The consumable mounting slot is configured to install an infusion consumable. The infusion consumable includes a mounting portion, a mounting hole is provided on the mounting portion, an identification piece is provided in the mounting hole, a depth of the mounting hole is greater than or equal to a thickness of the identification piece, and the identification piece includes a magnetic piece.

[0034] The method comprises:

[0035] Acquiring the magnetic field strength and / or direction of the identification element on the infusion consumable;

[0036] The model of the infusion consumable is determined according to the magnetic field strength and / or direction of the identification element.

[0037] The method for detecting the model of infusion consumables in the embodiment of the present application is to set the identification piece on the infusion consumable to a structure including a magnetic piece, and judge the model of the infusion consumable according to the magnetic field strength and / or direction of the identification piece. Since the method for obtaining and judging the magnetic field strength and direction are relatively simple, this can reduce the difficulty of recognition, simplify the recognition process, improve the recognition efficiency, and improve the recognition accuracy.

[0075] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0076] The terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0077] In addition, in the present application, directional terms such as "front" and "rear" are defined relative to the orientation of the components in the drawings. It should be understood that these directional terms are relative concepts. They are used for relative description and clarification, and they can change accordingly according to the changes in the orientation of the components in the drawings.

[0078] In the embodiments of the present application, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0079] Hereinafter, exemplary application scenarios of the embodiments of the present invention will be introduced with reference to the accompanying drawings.

[0080] The present invention provides an infusion consumable material, which is applied to an infusion device, and the infusion device includes but is not limited to a nutrition pump, an infusion pump, etc.

[0081] like Figure 1 As shown, the infusion consumable 100 may include a mounting portion 110 and an infusion pipeline 120, wherein the infusion pipeline 120 is fixedly connected to the mounting portion 110, and the mounting portion 110 is used to connect the infusion consumable 100 to a nutrition pump, so that the infusion consumable 100 can be infused to the user.

[0082] Exemplarily, the infusion pipeline 120 may include a liquid inlet 121 and a liquid outlet 122, and a silicone hose region 123 connected to the roller of the infusion device is provided at the liquid inlet 121 and the liquid outlet 122. When in use, liquid may enter from the liquid inlet 121 and flow out from the liquid outlet 122 through the silicone hose region 123. The liquid outlet 122 may be connected to a user.

[0083] It should be noted that the structure of the infusion pipeline 120 includes but is not limited to the structure shown in the figure, and the infusion pipeline 120 of different models of infusion equipment may be different. The infusion pipeline 120 in the embodiment of the present application will not be further described.

[0084] In some embodiments, Figure 2 As shown, a mounting hole 111 is provided on the mounting portion 110, and an identification member 130 is provided in the mounting hole 111. The depth of the mounting hole 111 is greater than the thickness of the identification member 130. The identification members 130 on different types of infusion consumables 100 have different installation depths in the mounting hole 111, and / or the identification members 130 on different types of infusion consumables 100 have different installation directions in the mounting hole 111.

[0085] Exemplarily, the different installation depths of the identification members 130 on different models of infusion consumables 100 in the mounting hole 111 refer to: the heights from the top of the identification member 130 to the opening of the mounting hole 111 are different, or the heights from the bottom of the identification member 130 to the bottom of the mounting hole 111 are different.

[0086] Exemplarily, the identification member 130 may include a first end 131 and a second end 132. The different installation directions of the identification members 130 on different types of infusion consumables 100 in the mounting hole 111 refer to: the first end 131 of the identification members 130 on different types of infusion consumables 100 have different orientations. For example, the first end 131 facing the bottom end of the mounting hole 111 is one direction, and the first end 131 facing the open end of the mounting hole 111 is another direction.

[0087] The infusion consumable 100 in the embodiment of the present application can be provided with the identification member 130, so that the infusion device used with the infusion consumable 100 can easily identify the model of the infusion consumable 100, so as to subsequently select the infusion mode corresponding to the infusion consumable 100. By providing the mounting hole 111 on the mounting portion 110, a mounting position can be provided for the identification member 130. In addition, the processing technology of the hole-shaped structure is relatively simple, which can reduce the processing cost of the infusion consumable 100.

[0088] Different types of infusion consumables 100 can be distinguished by the depth of the identification member 130 in the mounting hole 111, so that one identification member 130 can be used to identify multiple types of infusion consumables 100. In addition, the structure of the infusion device corresponding to the infusion consumable 100 can be simplified, thereby reducing the cost of the infusion device.

[0089] In addition, by setting the depth of the mounting hole 111 to be greater than the thickness of the identification piece 130 , the identification piece 130 can be set invisibly on the infusion consumable 100 , thereby preventing the identification piece 130 from being scratched during use and damaging the identification piece 130 .

[0090] In some embodiments, Figure 3 As shown, the identification member 130 may be a cylindrical structure. Of course, in other embodiments, the identification member 130 may also be a structure of other shapes, such as a triangular prism, a quadrangular prism, etc. The specific shape of the identification member 130 is not further limited in the embodiment of the present application.

[0091] By configuring the identification member 130 to be a cylindrical structure, the processing steps of the identification member 130 can be simplified, thereby reducing the production cost of the infusion consumable 100 .

[0092] like Figure 3 As shown, the identification member 130 includes two ends, namely a first end 131 and a second end 132. The first end 131 and the second end 132 have different features.

[0093] By setting the features of the two ends of the identification member 130 differently, the installation direction can be distinguished when installing the identification member 130. This can prevent installation errors. In addition, by changing the installation direction of the identification member 130, the models or types of infusion devices can be increased.

[0094] It is understandable that the two ends of the identification member 130 face different directions in the mounting hole 111, which means that the identification member 130 is installed in different directions in the mounting hole 111. For example, the first end 131 of the identification member 130 faces the bottom of the mounting hole 111, which is opposite to the second end 132 of the identification member 130 facing the bottom of the mounting hole 111.

[0095] In some embodiments, the identification member 130 may include a magnetic member. Exemplarily, the identification member 130 is a magnetic member. The magnetic member includes two polarities, a south pole and a north pole, and the two poles of the magnetic member are respectively located at the two ends of the magnetic member. Since the directions of the magnetic fields generated by the south pole and the north pole are different, the characteristics of the two ends of the identification member 130 including the magnetic member are different.

[0096] The infusion consumable 100 in the embodiment of the present application can reduce the cost of the infusion consumable 100 by setting the identification member 130 to include a magnetic member, because the cost of the magnetic member is relatively low. In addition, the magnetic member has magnetism and polarity, so different identification parameters can be provided for distinguishing different infusion consumables 100, thereby providing the possibility of increasing the models of the infusion consumable 100. In addition, identification parameters can also be provided for the identification of the infusion device, so that the infusion device can identify different infusion consumables 100.

[0097] Of course, in other embodiments, the identification member 130 may also be a cylindrical structure with a magnetic member disposed at one end. Of course, in other embodiments, the identification member 130 may also be a structure of other materials. In the embodiment of the present application, the specific structure of the identification member 130 is not further limited.

[0098] In some embodiments, the ratio of the depth of the mounting hole 111 to the thickness of the identification member 130 may be greater than or equal to 2. For example, the depth of the mounting hole 111 may be 2, 2.5, 3, 3.5, 4 or more times the thickness of the identification member 130 .

[0099] In the embodiment of the present application, the quantitative relationship between the depth of the mounting hole 111 and the thickness of the identification member 130 is not limited.

[0100] It is understandable that the proportional relationship between the thickness of the identification member 130 and the depth of the mounting hole 111 can determine the number of models of the infusion consumable 100. In other words, by changing the ratio of the depth of the mounting hole 111 and the thickness of the identification member 130, the number of installation positions in the mounting hole 111 of the identification member 130 can be changed, thereby changing the number of models of the infusion consumable. Specifically, the proportional relationship between the depth of the mounting hole 111 and the thickness of the identification member 130 can be set according to specific needs and actual conditions, and is not further limited in the embodiments of the present application.

[0101] like Figure 4A As shown, the mounting hole 111 may be a cylindrical hole-shaped structure.

[0102] It should be noted that the cylindrical hole structure is easy to process, which can simplify the processing technology of the mounting hole 111 and further reduce the production cost of the infusion consumable 100 .

[0103] Of course, in some other embodiments, the mounting hole 111 can also be set to a structure of other shapes, for example, a triangular prism-shaped or quadrangular prism-shaped hole structure, which can be specifically set according to the specific structure of the identification piece 130. In the embodiment of the present application, the specific structure of the mounting hole 111 is not further limited.

[0104] Continue to see Figure 4A As shown, the identification member 130 is located at the bottom of the mounting hole 111. The mounting holes 111 of different types of infusion consumables 100 have different depths.

[0105] For example, Figure 4A and Figure 4B As shown, the thickness of the identification member 130 of the two types of infusion consumables 100 is the same, and the depth of the mounting hole 111 is different. The identification member 130 of the two types of infusion consumables 100 is arranged at the bottom of the mounting hole 111, so that Figure 4A The distance h1 from the second end 132 of the identification member 130 of the infusion consumable 100 to the opening of the mounting hole 111, and Figure 4B The distance h2 from the second end 132 of the identification piece 130 of the infusion consumable 100 to the opening of the mounting hole 111 is different.

[0106] In the embodiment of the present application, there is no limitation on the depth of the mounting hole 111 and the size of the identification member 130. For example, the depth of the mounting hole 111 can be 2 mm, 3 mm, 4 mm, 5 mm, 6 mm, etc., and the thickness of the identification member 130 can be 1 mm, 2 mm, 3 mm, etc.

[0107] By arranging the identification member 130 at the bottom of the mounting hole 111 and setting the mounting holes 111 of different types of infusion consumables 100 to have different depths, the distances from the top of the identification member 130 to the opening of the mounting hole 111 of different types of infusion consumables 100 can be different. This can provide identification parameters for the identification of the infusion device, such as height information or magnetic flux information, so that the infusion device can identify different infusion consumables.

[0108] Of course, in some other embodiments, the depths of the mounting holes 111 of different types of infusion consumables 100 can be set to be the same, and the thicknesses of the identification members 130 can also be set to be the same. By changing the structure of the mounting holes 111, the identification members 130 can be fixed at different depths of the mounting holes 111.

[0109] For example, Figure 4C As shown, a limiting structure 140 may be provided in the mounting hole 111 , wherein the limiting structure 140 is used to limit the identification member 130 to different heights in the mounting hole 111 .

[0110] The infusion consumable 100 in the embodiment of the present application can limit the identification member 130 to different heights of the mounting hole 111 by setting a limiting structure 140 in the mounting hole 111, and provide support for the identification member 130 to prevent the identification member 130 from shifting in the mounting hole 111, thereby ensuring that the infusion consumable 100 can be used normally and extending the service life of the infusion consumable 100.

[0111] Exemplarily, the limiting structure 140 can be an annular plate-like structure disposed in the mounting hole 111, wherein the outer ring of the annular plate-like structure is connected to the inner wall of the mounting hole 111, and the inner ring of the annular plate-like structure extends in a direction close to the central axis of the mounting hole 111. The diameter of the inner ring of the annular plate-like structure is greater than the outer diameter of the identification member 130. So that the limiting structure 140 can play a supporting role for the identification member 130. Of course, in some other embodiments, the limiting structure 140 can also be a plate-like structure disposed in the mounting hole 111, wherein the outer wall of the plate-like structure is fixedly connected to the inner wall of the mounting hole 111.

[0112] In other embodiments, Figure 5 As shown, the limiting structure 140 can also be set as a screw structure. For example, the limiting structure 140 passes through the side wall of the mounting hole 111 in the vertical direction of the central axis of the mounting hole 111 and is movably connected to the mounting hole 111. The length of the limiting structure 140 is greater than the wall thickness of the mounting hole 111. The limiting structure 140 can be rotated in different directions to move toward or away from the inner side of the mounting hole 111.

[0113] Figure 6The figure shows a state where the limiting structure 140 is a screw rod and the limiting structure 140 is turned until a part of the structure is located in the mounting hole 111. Figure 6 As shown, when the limiting structure 140 is rotated until a part of the structure is located in the mounting hole 111 , it can limit the identification member 130 .

[0114] It should be noted that in the embodiment of the present application, the number of the limiting structures 140 located at the same height is not limited. For example, there may be multiple limiting structures 140 located at the same height, and the multiple limiting structures 140 may be arranged at intervals around the mounting hole 111.

[0115] Alternatively, there may be only one limiting structure 140 at the same height, which is disposed outside the mounting hole 111 , and the limiting structure 140 may be relatively large in size. For example, the limiting structure 140 may be larger in size than the radius of the mounting hole 111 .

[0116] In the embodiment of the present application, the specific structure of the limiting structure 140 and the number of limiting structures 140 at the same height are not further limited. As long as the limiting structure 140 can achieve its function, it belongs to the protection scope of the embodiment of the present application.

[0117] In one possible implementation, Figure 7 As shown, a plurality of limiting structures 140 are arranged at intervals along the depth direction of the mounting hole 111 .

[0118] The infusion consumable 100 in the embodiment of the present application is configured with a plurality of limiting structures 140 , and the plurality of limiting structures 140 are spaced apart along the depth direction of the mounting hole 111 , so as to realize setting the identification member 130 at different heights in the mounting hole 111 .

[0119] In one possible implementation, Figure 8 As shown, the infusion consumable 100 may further include a fixing member 150. The fixing member 150 is disposed between the identification member 130 and the mounting hole 111, and the fixing member 150 is used to fix the identification member 130 to the mounting hole 111. Exemplarily, the fixing member 150 may be glue or a viscous material.

[0120] The infusion consumable 100 in the embodiment of the present application can improve the connection stability between the identification member 130 and the mounting hole 111 and extend the service life of the infusion consumable 100 by providing the fixing member 150 .

[0121] The infusion consumable 100 in the embodiment of the present application can reduce the difficulty of setting the fixing member 150 by setting the fixing member 150 as glue or viscous material. In other words, the fixing member 150 formed by glue or viscous material can change with the shape of the identification member 130 and the mounting hole 111, and fit the surface of the identification member 130 and the mounting hole 111, which is convenient for setting. In addition, the fixing member 150 formed by glue or viscous material can be a thinner layer, occupying a smaller volume, thereby reducing the influence of the fixing member 150 on the identification member 130, thereby improving the accuracy of being identified when it is later matched with the infusion device.

[0122] Of course, in other embodiments, the fixing member 150 may also be a fixing member 150 in other forms, for example, a rubber ring, etc. In the embodiment of the present application, the specific structure of the fixing member 150 is not further limited.

[0123] It should be noted that the infusion consumable 100 in the embodiment of the present application can distinguish the model of the infusion consumable 100 by setting the identification member 130 at different depths of the installation hole 111 and / or the installation direction of the identification member 130.

[0124] That is, the heights from the bottom of the identification piece 130 on different types of infusion consumables 100 to the bottom of the mounting hole 111 are different, and / or the installation directions of the identification piece 130 on different types of infusion consumables 100 in the mounting hole 111 are different.

[0125] In other words, different types of infusion consumables 100 can be distinguished by the depth of the identification member 130 in the mounting hole 111. Alternatively, different types of infusion consumables 100 can be distinguished by the installation direction of the identification member 130 in the mounting hole 111. Alternatively, different types of infusion consumables 100 can be distinguished by the depth of the identification member 130 in the mounting hole 111 and the installation direction of the identification member 130 in the mounting hole 111.

[0126] For example, Figure 8 As shown, the height from the bottom end of the identification member 130 to the bottom end of the mounting hole 111 is a first height H1 , and the first end 131 of the identification member 130 faces the bottom end of the mounting hole 111 .

[0127] like Fig. 9 As shown, the height from the bottom end of the identification member 130 to the bottom end of the mounting hole 111 is a second height H2 , and the first end 131 of the identification member 130 faces the bottom end of the mounting hole 111 .

[0128] Figure 8 and Fig. 9Shown in the figure are mounting holes 111 and identification members 130 provided on two types of infusion consumables 100 , wherein the identification members 130 on the two types of infusion consumables 100 have the same mounting direction and different heights in the mounting holes 111 .

[0129] like Fig.10 As shown, the height from the bottom end of the identification member 130 to the bottom end of the mounting hole 111 is a first height H1 , and the second end 132 of the identification member 130 faces the bottom end of the mounting hole 111 .

[0130] Figure 8 and Fig.10 Shown in the figure are the mounting holes 111 and identification members 130 provided on two types of infusion consumables 100 , wherein the identification members 130 on the two types of infusion consumables 100 have different mounting directions and the same height in the mounting holes 111 .

[0131] Fig. 9 and Fig.10 Shown in the figure are the mounting holes 111 and identification members 130 provided on two types of infusion consumables 100 , wherein the identification members 130 on the two types of infusion consumables 100 have different mounting directions and different heights in the mounting holes 111 .

[0132] In this way, by changing the installation position and direction of the identification piece 130 on the infusion consumable 100 , different models of the infusion consumable 100 can be marked, thereby providing the possibility of increasing the models of the infusion consumable 100 , thereby increasing the scope of application of the infusion consumable 100 .

[0133] In one embodiment, if Figure 8 , Fig. 9 and Fig.10 As shown, single-channel infusion consumables and dual-channel infusion consumables can be distinguished by the installation direction. Different models of infusion consumables with the same channel can be distinguished by the installation depth. Among them, the dual-channel infusion consumable is provided with an additional liquid filling tube compared to the single-channel infusion consumable, and the liquid filling tube is located at the liquid inlet end of the infusion consumable.

[0134] Exemplarily, the infusion consumable with the first end 131 of the identification member 130 facing the bottom of the mounting hole 111 is used as a single-channel infusion consumable. When the first end 131 of the identification member 130 faces the bottom of the mounting hole 111 and the depth of the identification member 130 in the mounting hole 111 is different, it can be indicated that the models of the two single-channel infusion consumables are different.

[0135] The infusion consumable with the second end 132 of the identification member 130 facing the bottom of the mounting hole 111 is used as a dual-channel infusion consumable. When the second end 132 of the identification member 130 faces the bottom of the mounting hole 111 and the depth of the identification member 130 in the mounting hole 111 is different, it can be indicated that the models of the two dual-channel infusion consumables are different.

[0136] …It should be noted that the different depths of the identification member 130 in the mounting hole 111 can be achieved by changing the depth of the mounting hole 111, or by changing the location of the identification member 130 in the mounting hole 111. In the embodiment of the present application, the specific method of changing the depth of the identification member 130 in the mounting hole 111 is not further limited in the embodiment of the present application.

[0137] In one possible implementation, Fig.11 As shown, there are a plurality of mounting holes 111. The plurality of mounting holes 111 are arranged at intervals on the mounting portion 110, and each mounting hole 111 is configured to be provided with an identification member 130.

[0138] The infusion consumable 100 in the embodiment of the present application is provided with a plurality of mounting holes 111, and each mounting hole 111 is configured to be provided with an identification member 130. In this way, identification parameters for distinguishing different infusion consumables 100 can be further increased, thereby providing the possibility of increasing the models of the infusion consumable 100. In addition, more identification parameters can be provided for the identification of the infusion device, so that the infusion device can identify different infusion consumables 100.

[0139] It should be noted that in the embodiment of the present application, the number of mounting holes 111 is limited. For example, it can be 1, 2, 3, 4, 5 or more. The specific number can be set according to needs and is not further limited in the embodiment of the present application.

[0140] In addition, the plurality of mounting holes 111 may be arranged in an array on one side of the mounting portion 110 , or may be arranged irregularly. In the embodiment of the present application, the arrangement of the plurality of mounting holes 111 is not further limited.

[0141] It should be noted that different models of infusion consumables 100 (e.g., dual-channel infusion consumables 100 and single-channel consumables) can adapt to different application scenarios, thereby expanding the range of models of infusion consumables 100. By using the setting direction and setting height of the identification element 130 as a reference for differentiation, the difficulty of distinguishing the models of consumables can be reduced, and the cost can be reduced. In addition, the cost of the infusion device corresponding to the infusion consumable 100 can also be reduced.

[0142] The infusion device 200 provided in the embodiment of the present application is described below with reference to the accompanying drawings.

[0143] like Fig.12 As shown, the present application provides an infusion device 200, which may include a consumables installation slot 230 and a consumables detection device 240. Fig.13As shown, the consumable installation slot 230 is configured to install the above-mentioned infusion consumable 100. The consumable detection device 240 is arranged opposite to the identification member 130 of the infusion consumable 100 to identify the model of the infusion consumable 100.

[0144] The infusion device 200 in the embodiment of the present application is provided with a consumable installation slot 230 so that the infusion consumable 100 can be installed on the infusion device 200 to ensure that the infusion consumable 100 can be stably connected to the infusion device 200 during use. The consumable detection device 240 is provided to further identify the model of the infusion consumable 100 installed on the infusion device 200 so that the infusion device 200 can determine a suitable infusion mode according to the model of the infusion consumable 100.

[0145] It should be noted that, when the identification component 130 of the infusion consumable 100 is a magnetic component.

[0146] like Fig.14 As shown, the consumables detection device 240 may include:

[0147] The consumable detection component 210 is configured to obtain the magnetic field strength and / or direction of the identification component 130 on the preset infusion consumable 100 .

[0148] The controller 220 is configured to determine the model of the preset infusion consumable 100 according to the magnetic field strength and / or direction of the identification element 130 .

[0149] Exemplarily, the consumables detection element 210 is electrically connected to the controller 220. By connecting the controller 220 to the consumables detection element 210, the controller 220 can determine the model of the preset infusion consumables 100 according to the magnetic field strength and / or direction of the identification element 130.

[0150] The infusion device 200 in the embodiment of the present application, by setting the identification member 130 as a magnetic member, and judging the model of the preset infusion consumable 100 according to the magnetic field strength and / or direction of the identification member 130, can simplify the identification process because the acquisition method and judgment method of the magnetic field strength and / or direction are relatively simple. In addition, there are many types of devices that can identify the magnetic field strength and / or direction, so the selection range of consumable detection parts can be expanded, which is conducive to the large-scale production of the infusion device 200 and can also provide a possibility for reducing the cost of the infusion device 200.

[0151] Optionally, the controller 220 is further configured as:

[0152] Storing model information of multiple models of infusion consumables 100;

[0153] Compare the magnetic field strength and / or direction information obtained by the consumables detection component 210 with the model information;

[0154] According to the comparison result, the model of the preset infusion consumable 100 is determined.

[0155] Optionally, the controller 220 is further configured to: if the magnetic field strength and / or direction information obtained by the consumables detection component 210 is the same as one of the model information, determine that the model corresponding to the model information is the model of the preset consumables.

[0156] It should be noted that the model information is the magnetic field strength and / or direction information corresponding to the infusion consumable 100 , and one model of infusion consumable 100 corresponds to one model information, and different models of infusion consumables 100 correspond to different model information.

[0157] Optionally, the consumable material detection component 210 may be a sensor, for example, a magnetic induction sensor, a linear Hall sensor or a magnetoresistive sensor, etc. In the embodiment of the present application, the specific structure of the consumable material detection component 210 is not further limited.

[0158] Of course, in some embodiments, the consumable detection member 210 may also be configured to obtain the installation direction and installation depth of the identification member 130 on the preset infusion consumable 100 in the installation hole 111. The controller 220 is configured to determine the model of the preset infusion consumable 100 according to the installation direction and installation depth of the identification member 130. Exemplarily, the consumable detection member 210 may be set as a distance sensor, etc. In the embodiment of the present application, the information obtained by the consumable detection member 210 is not further limited.

[0159] It should be noted that the infusion device 200 is also provided with other structures such as a shell and a display screen. In the embodiment of the present application, no further limitation is made to the other structures of the infusion device 200.

[0160] An embodiment of the present application also provides a method for detecting the model of an infusion consumable, which is applied to an infusion device. The infusion device is provided with a consumable mounting slot and a consumable detection device. The consumable mounting slot is configured to install an infusion consumable. The infusion consumable includes a mounting portion, a mounting hole is provided on the mounting portion, an identification piece is provided in the mounting hole, the depth of the mounting hole is greater than the thickness of the identification piece, and the identification piece is a magnetic piece.

[0161] Fig.15 A flow chart of a method for detecting an infusion consumable model provided in one embodiment of the present application.

[0162] The method is executed by part or all of the infusion device, and the so-called part of the infusion device is the processor of the infusion device. The following describes the method for detecting the model of the infusion consumables with the infusion device as the execution subject.

[0163] like Fig.15 As shown, the method comprises the following steps:

[0164] S301: Acquire the magnetic field strength and / or direction of the identification element on the infusion consumable.

[0165] The following is a detailed description of S301:

[0166] Since there are many types of infusion consumables, and the identification parts of different types of infusion consumables are set in different directions and / or different positions, the acquired magnetic field strength and direction may be affected. Since the acquisition and judgment methods of the magnetic field strength and direction are relatively simple, this can reduce the difficulty of identification, simplify the identification process, improve the identification efficiency, and improve the identification accuracy.

[0167] Optionally, before obtaining the magnetic field strength and / or direction of the identification element on the infusion consumable, it also includes installing the preset infusion consumable on the consumable mounting slot of the preset infusion device, and the consumable mounting slot is used to fix the preset infusion consumable, which can improve the accuracy of the detection result.

[0168] S302: Determine the model of the infusion consumable according to the magnetic field strength and / or direction of the identification element.

[0169] The following is a detailed description of S302:

[0170] like Fig.16 As shown, optionally, judging the model of the infusion consumable according to the magnetic field strength and / or direction of the identification element specifically includes:

[0171] S3021: Storing model information of multiple models of infusion consumables in a preset storage module;

[0172] S3022: Compare the acquired magnetic field strength and / or direction information with the model information in the preset storage module;

[0173] S3023: Determine the model of the preset infusion consumables according to the comparison result of the comparison module.

[0174] Optionally, the model of the preset infusion consumable is determined according to the comparison result of the comparison module, including: if the acquired magnetic field strength and / or direction information is the same as one of the model information, then determining that the model corresponding to the model information is the model of the preset consumable.

[0175] It should be noted that in some solutions where the identification element does not include a magnetic element, this method can also be used to check the model of the infusion consumable. For example, the installation direction and / or installation depth of the identification element on the infusion consumable in the installation hole can be directly obtained; then the model of the infusion consumable is determined based on the installation direction and / or installation depth of the identification element. As long as different models of infusion consumables can be distinguished by installation depth and installation direction, it will be fine.

[0176] The method for detecting the model of infusion consumables in the embodiment of the present application is to set the identification component of the infusion consumable to a structure including a magnetic component, and judge the model of the infusion consumable according to the magnetic field strength and / or direction of the identification component. Since the method for obtaining and judging the magnetic field strength and direction are relatively simple, this can reduce the difficulty of identification, simplify the identification process, improve the identification efficiency, and improve the identification accuracy.
