[0021] The technical solutions in the embodiments of the present application will be clearly and completely described 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.

[0022] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0023] The infusion pump described herein is a general term for an infusion pump and an injection pump. The infusion pump includes an infusion pump host (e.g., an infusion pump host and / or an injection pump host), in which an infusion pump drive mechanism (e.g., an infusion pump drive mechanism / injection pump drive mechanism), an infusion set mounting mechanism (e.g., an infusion tube mounting groove / injection set mounting groove) and a processor are arranged, and the processor drives the infusion pump drive mechanism to squeeze the fluid in the infusion set mounted on the infusion set mounting mechanism, so that the fluid flows in a preset direction, for example, moving along the infusion / injection direction during infusion.

[0024] In some embodiments of the present invention, the infusion pump host referred to in the present invention has the same structure as other infusion pump hosts, and the stacking mechanisms of the infusion pump host and other infusion pump hosts are also the same in structure; in the case where the infusion pump host is different from other infusion pump hosts, the stacking mechanisms of the two are different, which will be clearly pointed out. Therefore, the structure of other infusion pump hosts can be known by describing the structure of the infusion pump host, and the stacking mechanisms of other infusion pump hosts can also be known by describing the stacking mechanisms of the infusion pump host.

[0025] An infusion pump provided in one of the embodiments of the present application is used in conjunction with a stacking mechanism to facilitate the movement of the infusion pump. When a plurality of infusion pumps are required to be used in combination, the infusion pump host is connected to other infusion pump hosts through the stacking mechanism, thereby greatly improving the user's convenience. In addition, a first shell card slot and a second shell card slot are provided on the bottom and / or back of the infusion pump host, so that the stacking mechanism is connected to the infusion pump host, which is beneficial to protecting the overall appearance of the infusion pump host and is convenient for cleaning. In addition, the stacking mechanism can also take into account the handle function to facilitate the movement of the infusion pump host.

[0026] In one embodiment, see Figure 1 , Figure 1The driving mechanism of the infusion pump 200 is shown. The infusion pump 200 is used in conjunction with the infusion tube 220 (collectively referred to as an infusion device together with the syringe). When performing infusion, the infusion tube 220 is set in the infusion tube groove 240; the processor 250 in the infusion pump 200 issues instructions such as speed or position, and drives the motor 260 to work according to the specified speed and direction. During the rotation process, the motor 260 drives the camshaft 231 connected thereto to rotate; during the rotation process of the camshaft 231, the pump plate group 232 on the camshaft 231 performs linear reciprocating motion, that is, the pump plates on the pump plate group 232 perform linear reciprocating motion in sequence. The pump plate group 232 cooperates with the extrusion plate 234 to reciprocate and release the outer wall of the infusion tube 220 in sequence, driving the liquid in the infusion tube 220 to continue to flow in a directional manner. A deceleration mechanism can also be provided between the motor 260 and the camshaft 231 to ensure that the speed of the pump plate group 232 is stable and uniform.

[0027] In one embodiment, see Figure 2 , Figure 2 The driving mechanism of the syringe pump 300 is shown. The syringe pump 300 is used in conjunction with a syringe 390 (collectively referred to as an infusion set together with an infusion tube). When performing an injection, the syringe pump 300 is set in a syringe slot (not shown). The push-pull box 360 is used to clamp the piston 370 of the syringe 390. The processor 310 of the syringe pump 300 sends instructions such as rotation speed or position to the motor 320, and the motor 320 drives the screw rod 330 and the nut 340 through the reduction mechanism to convert the rotational motion of the motor 320 into the linear motion of the nut 340. The nut 340 is connected to the push rod 350, and the push rod 350 is connected to the push-pull box 360. The push-pull box 360 can push the piston 370 of the matching syringe 390 for injection and infusion. By setting the rotation speed of the motor 320, the propulsion speed of the matching syringe 390 can be adjusted, thereby adjusting the given infusion dose and infusion speed.

[0028] First, the side where the display of the infusion pump host is located is determined as the front of the infusion pump host, and the side parallel to the front is determined as the back of the infusion pump host. When the user normally operates the infusion pump host, the lower surface of the infusion pump host is determined as the bottom surface of the infusion pump host.

[0029] Secondly, the combined use of infusion pumps includes combining multiple infusion pumps to start infusion in a preset order, or stacking multiple infusion pumps to save space.

[0030] In one embodiment, see Figure 3A , 3B and 3C, Figure 3A , Figure 3B and Figure 3COne of the connection modes of the infusion pump 10 and the stacking mechanism 20 is shown. The infusion pump host 10 includes a first housing card slot 101 disposed on the bottom surface of the infusion pump host 10, and a second housing card slot 102 disposed on the bottom surface of the infusion pump host 10. The stacking mechanism 20 includes a fixed end 201 and a stacking end 202. When the infusion pump host 10 is used alone, the first housing card slot 101 is connected to the fixed end 201, and the stacking end 202 is the fulcrum for the user to move the infusion pump host 10, that is, the user can move the infusion pump host 10 by holding the stacking end 202. When the infusion pump host 10 is used in combination with the infusion pump host 30, the structure of the infusion pump host 30 is the same as that of the infusion pump host 10, the first shell card slot 101 of the infusion pump host 10 is connected to the fixed end 201 of the stacking mechanism 20 used with it, the second shell card slot 102 of the infusion pump host 10 is connected to the stacking end 402 of the stacking mechanism 40 used with the infusion pump host 30, and the first shell card slot 301 of the infusion pump host 30 is connected to the fixed end 401 of the stacking mechanism 40 used with it, so that the infusion pump host 30 is connected to the infusion pump host 10 through the stacking mechanism 40. The connection between the infusion pump host 10 and the infusion pump host 30 can be quickly achieved without disassembling the stacking mechanism 20 / 40 of the infusion pump host 10 / 30; and the first shell card slot 101 / 301 in the infusion pump host 10 / 30 is arranged on the bottom surface, and the second shell card slot 102 / 302 is also arranged on the bottom surface, which will not cause the liquid that may leak in the infusion to remain on the surface (front or top surface) of the infusion pump host 10 / 30, and it is beautiful and easy to clean; in addition, this connection method can be connected more firmly. When multiple infusion pumps are used in combination, the center of gravity is in the middle of the infusion pump host, and the user is less labor-intensive when lifting.

[0031] In one embodiment, the stacking mechanism is only used to connect the infusion pump host to other infusion pump hosts. The stacking mechanism can be used to easily connect the infusion pump host to other infusion pump hosts. The infusion pump includes a second housing card slot 102 disposed on the bottom or back of the infusion pump host 10, and the other infusion pump includes a first housing card slot 301 disposed on the bottom or back of the other infusion pump host 30. Figure 3DThe infusion pump further comprises a hand-held part 210, the hand-held part 320 is connected to the infusion pump host 10, and the other infusion pumps 30 are used in conjunction with the stacking mechanism 40, and the parts where the stacking end 402 and the fixed end 401 are located are of a split structure with the hand-held part 210. When the infusion pump host 10 is used in combination with the other infusion pump host 30, the second shell card slot 102 of the infusion pump host 10 is connected to the stacking end 402 of the stacking mechanism, and the first shell card slot 301 of the other infusion pump host 30 is connected to the fixed end 401 of the stacking mechanism, so that the other infusion pump host 30 is connected to the infusion pump host 10 through the stacking mechanism 40; wherein, the infusion pump and the other infusion pumps can both be provided with the first shell card slot and the second shell card slot in the same position; or the infusion pump can only be provided with the second shell card slot, and the other infusion pumps can only be provided with the first shell card slot. When the infusion pump host 10 is used alone, the carrying part serves as a fulcrum for moving the infusion pump host 10; when the infusion pump host 10 is used in combination with other infusion pump hosts 30, the carrying part can serve as a fulcrum for the infusion pump combination.

[0032] In order to facilitate the user to move the infusion pump host assembly, the hand-held part 210 is connected to the infusion pump host 30. In an optional implementation, please refer to Figure 3D and Figure 3E The hand-held part 210 is connected to the third housing card slot 103 on the back of the infusion pump host 10. The hand-held part 210 serves as a fulcrum, so that the user can move the combination of the infusion pump host by holding the hand-held part 210. In another optional implementation, please refer to Figure 3F A hand-held component slot is provided at the top of the infusion pump host 30 (the side opposite to the bottom surface), and the hand-held component 210 is connected to the hand-held component slot. The hand-held component 210 serves as a fulcrum, allowing the user to move the combination of the infusion pump host by holding the hand-held component 210.

[0033] In one embodiment, see Figure 4A , Figure 4AAnother connection method of the infusion pump 10 / 30 and the stacking mechanism 20 / 40 is shown. A first housing card slot 101 and a second housing card slot 102 are provided on the back of the infusion pump host 10. When the infusion pump host 10 is used alone, the first housing card slot 101 is connected to the fixed end 201 of the stacking mechanism 20, and the stacking end 202 is the fulcrum for the user to move the infusion pump host 10, that is, the user can move the infusion pump host 10 by holding the stacking end 202. When the infusion pump host 10 is used in combination with the infusion pump host 30, the structure of the infusion pump host 30 is the same as that of the infusion pump host 10, the first housing card slot 101 of the infusion pump host 10 is connected to the fixed end 201 of the stacking mechanism 20 used with it, the second housing card slot 102 of the infusion pump host 10 is connected to the stacking end 402 of the stacking mechanism 40 used with the infusion pump host 30, and the first housing card slot 301 of the infusion pump host 30 is connected to the fixed end 401 of the stacking mechanism 40 used with it, so that The infusion pump host 30 is connected to the infusion pump host 10 through the stacking mechanism 40, so the connection between the infusion pump host 10 and the infusion pump host 30 can be quickly realized without disassembling the stacking mechanism 20 / 40 matched with the infusion pump host 10 / 30; and the first shell card slot 101 / 301 in the infusion pump host 10 / 30 is set on the back, and the second shell card slot 102 / 302 is also set on the back, which will not cause the liquid that may leak in the infusion to stay on the surface (front or top surface) of the infusion pump host 10 / 30, which is beautiful and easy to clean.

[0034] In one embodiment, see Figure 4B and Figure 4C , when the stacking mechanism further includes a handheld part 210 that is independent of the parts where the stacking end 202 and the fixed end 201 are located. When the infusion pump host 10 is used in combination with the infusion pump host 30, the second shell card slot 102 of the infusion pump host 10 is connected to the stacking end 402 of the stacking mechanism, and the first shell card slot 302 of the infusion pump host 30 is connected to the fixed end 402 of the stacking mechanism, so that the infusion pump host 30 is connected to the infusion pump host 10 through the stacking mechanism 20. The handheld part 210 is connected to the infusion pump host 10. In an optional implementation, as Figure 4C As shown, the hand-held part 210 is connected to the third housing slot 103 of the infusion pump host 10, and the hand-held part 210 serves as a fulcrum, so that the user can move the combination of the infusion pump host by holding the hand-held part 210. In another optional implementation, as Figure 4B As shown, a hand-held component slot is provided at the top of the infusion pump host 10 (the side opposite to the bottom surface), and a hand-held component 210 is connected to the hand-held component slot. The hand-held component 210 serves as a fulcrum, allowing the user to move the combination of the infusion pump host by holding the hand-held component 210.

[0035] In one embodiment, see Figure 5 , Figure 5 Another connection method of the infusion pump 10 / 30 and the stacking mechanism 20 / 40 is shown. A first housing card slot 101 is provided on the back of the infusion pump host 10, and a second housing card slot 102 is provided on the bottom surface of the infusion pump host 10. When the infusion pump host 10 is used alone, the first housing card slot 101 is connected to the fixed end 201 of the stacking mechanism 20, and the stacking end 202 is the fulcrum for the user to move the infusion pump host 10, that is, the user can move the infusion pump host 10 by holding the stacking end 202. When the infusion pump host 10 is used in combination with the infusion pump host 30, the structure of the infusion pump host 30 is the same as that of the infusion pump host 10, the first shell card slot 101 of the infusion pump host 10 is connected to the fixed end 201 of the stacking mechanism 20 used with it, the second shell card slot 102 of the infusion pump host 10 is connected to the stacking end 402 of the stacking mechanism 40 used with the infusion pump host 30, and the first shell card slot 301 of the infusion pump host 30 is connected to the fixed end 401 of the stacking mechanism 40 used with it , so that the infusion pump host 30 is connected to the infusion pump host 10 through the stacking mechanism 40, and the connection between the infusion pump host 10 and the infusion pump host 30 can be quickly realized without disassembling the stacking mechanism 20 / 40 matched with the infusion pump host 10 / 30; and the first shell card slot 101 / 301 in the infusion pump host 10 / 30 is set on the back, and the second shell card slot 102 is set on the bottom, which will not cause the liquid that may leak in the infusion to stay on the surface (front or top surface) of the infusion pump host, which is beautiful and easy to clean.

[0036] In one embodiment, if Figures 3A-3C As shown, the stacking mechanism 20 further includes a height extension end 203, the stacking end 202 is parallel or nearly parallel to the fixed end 201, and is arranged between the stacking end 202 and the fixed end 201 through the height extension end 203, and there is a bending angle between the height extension end 203 and the stacking end 202, the bending angle can be 90°, or other reasonable angles less than 180° (approximately vertical), such as 100° or 80°, etc.; and there is a bending angle between the height extension end 203 and the fixed end 201, the bending angle can be 90°, or other reasonable angles less than 180° (approximately vertical), such as 100° or 80°, etc. The stacking mechanism 40 has the same structure as the stacking mechanism 20. The height extension end 403 of the stacking mechanism 40 can provide an accommodating space so that when the infusion pump host 10 and the infusion pump host 30 are stacked up and down, both can be stacked flatly and the two will not be in close contact, which is convenient for heat dissipation and / or wiring between the infusion pump host 10 / 30. Figure 3AAs shown, when the infusion pump host 10 is used in combination with the infusion pump host 30, the height extension end 403 is arranged on the back of the infusion pump host 30; in another optional implementation, ( Figure 3A (Not shown) When the infusion pump host 10 is used in combination with the infusion pump host 30, the height extension end 403 can also be located on the side of the infusion pump host 30.

[0037] In one embodiment, if Figure 5 As shown, since the first shell card slot 101 is set on the back of the infusion pump host 10, and the second shell card slot 102 is set on the bottom surface of the infusion pump host 10, the fixed end 201 and the stacking end 202 in the stacking mechanism 20 used in conjunction with the infusion pump host 10 are correspondingly set to be vertical or approximately vertical, so that when multiple infusion pump hosts are connected through the stacking mechanism 20, the multiple infusion pump hosts can be placed horizontally.

[0038] In one embodiment, if Figure 4A As described above, since the first shell card slot 101 is set on the back of the infusion pump host 10, and the second shell card slot 102 is set on the back of the infusion pump host 10, the fixed end 201 and the stacking end 202 in the stacking mechanism 20 used in conjunction with the infusion pump host 10 are correspondingly set to be horizontal or approximately horizontal, so that when multiple infusion pump hosts are connected through the stacking mechanism 20, the multiple infusion pump hosts can be placed horizontally.

[0039] In some embodiments, the first housing card slot and the second housing card slot of the infusion pump host can both be implemented by card slots protruding from the housing of the infusion pump host, or can both be implemented by grooves recessed in the housing of the infusion pump host, or can also be implemented by one card slot protruding from the housing of the infusion pump host and the other recessed in the housing of the infusion pump host according to the situation. For example: Figures 3A-3CAs shown, in order to avoid the overall thickness of the infusion pump host 10 and the stacking mechanism 20 being too thick after installation, and not to occupy too much internal space of the infusion pump host 10; the second housing card slot 102 of the infusion pump host 10 protrudes from the shell of the infusion pump host 10, and the second housing card slot 102 is used to connect with the stacking end 402 of the stacking mechanism 40 used in conjunction with other infusion pump hosts 30, and the stacking end 402 of the stacking mechanism 40 used in conjunction with the infusion pump host 30 is arranged outside the shell of the infusion pump host 10. The first housing card slot 101 of the infusion pump host 10 is recessed in the shell of the infusion pump host 10, and the first housing card slot 101 is used to connect with the fixed end 201 of the stacking mechanism 20 used in conjunction with the infusion pump host 10, and the fixed end 201 is arranged in the shell of the infusion pump host 10. In order to avoid occupying too much internal space of the infusion pump host 10, when the fixed end 201 is installed in the first host card slot 101, it can be flush with the bottom surface of the infusion pump host 10 (or nearly flush, and nearly flush can be understood as slightly protruding and close to flush; or slightly concave and close to flush) or protrude from the bottom surface; when the internal space of the infusion pump host is full, the fixed end can also be recessed in the bottom surface of the infusion pump host.

[0040] In some embodiments, such as Figures 3A-3C As shown, since the first shell slot 101 and the second shell slot 102 of the infusion pump host 10 are both arranged on the bottom surface of the infusion pump host 10, in order to avoid occupying too much space on the bottom surface of the infusion pump, the first shell slot 101 can also be arranged within the installation range of the second shell slot 102. For example, the first shell slot 101 can be arranged in the middle of the second shell slot 102. In this way, the fixed end 201 after installation can overlap with the stacking end 402 of other stacking mechanisms 40 after installation, and will not occupy too much space on the bottom surface of the infusion pump host 10; and the fixed end 201 is on the top and the stacking end 402 is on the bottom, and the installation order between the two will not affect each other. The stacking end 402 can be installed first, or the fixed end 201 can be installed first.

[0041] In some of the embodiments, the first shell slot and the second shell slot of the infusion pump host can be set on the bottom surface of the infusion pump host, or can be set at different positions on the bottom surface of the infusion pump host 10 (not shown).

[0042] In some embodiments, the second shell slot protrudes from the shell of the infusion pump host. When the second shell slot is used to connect with the stacking end of the stacking mechanism used with other infusion pump hosts, the stacking end of the stacking mechanism used with the infusion pump host is arranged on the outside of the shell of the infusion pump host. The first shell slot of the infusion pump host also protrudes from the shell of the infusion pump host. When the first shell slot is used to connect with the fixed end of the stacking mechanism used with the infusion pump host, the fixed end is arranged on the outside of the shell of the infusion pump host. The first shell slot and the second shell slot can be arranged overlappingly, for example, the first shell slot is arranged in the middle of the second shell slot; or Figure 4A and Figure 5 As shown, the first shell card slot 101 and the second shell card slot 102 are arranged separately, which will not cause the back of the infusion pump host to extend too deep, and can also help to stabilize the center of gravity and facilitate lifting.

[0043] In some embodiments, in order to ensure the firmness of the connection between the first housing slot 101 and the fixed end 201, some fasteners may be added between the first housing slot 101 and the fixed end 201 for fastening. The structure of one of the fasteners can be found in Figure 3A and Figure 6 As shown, the stacking mechanism 20 further includes a fixed end screw 204 and a first handle mounting hole 2041, wherein the first handle mounting hole 2041 is arranged on the fixed end 201; the infusion pump host 10 further includes a first host mounting hole 104, wherein the first host mounting hole 104 is arranged on the first housing card slot 101; the first handle mounting hole 2033 is connected with the first host mounting hole 104 by the fixed end screw 203 to reinforce the connection between the fixed end 201 and the first housing card slot 101 of the infusion pump host 10. The first handle mounting hole 2041 is connected with the first host mounting hole 104 on the first housing card slot 101 by the fixed end screw 204, so that the connection between the stacking mechanism 20 and the infusion pump host 10 is more stable. The fixed end screw 204 can be a hand screw, so that the user can connect the infusion pump host 10 with the stacking mechanism 20 without tools. In order to facilitate tightening of the fixed end screw 203 , the fixed end screw 204 includes an operating cap 2042 and a screw body 2043 , and the operating cap 2042 is a fulcrum for the user to tighten the screw body 2043 .

[0044] In some of the embodiments, in order to prevent the operating cap 2042 of the fixed end screw 204 from protruding too much when the infusion pump host 10 is used in combination with other infusion pump hosts 30, resulting in the inability to install the stacking end 402, an opening area 406 can also be set at the stacking end 402 of the stacking mechanism 40, so that when the infusion pump host 10 is combined with other infusion pump hosts 30, the first shell slot 101 is connected to the fixed end 201, and the second shell slot 102 is connected to the stacking end 402 in the stacking mechanism 40 provided with the infusion pump host 30, and the operating cap 2042 is located in the opening area 406.

[0045] In some embodiments, in order to ensure the firmness of the connection between the second housing card slot 102 and the stacking end 402, some fasteners may be added between the second housing card slot 102 and the stacking end 402 for fastening; Figure 3B , 3C and Figure 6 One of the fastening structures is shown. Figure 6 The stacking machine mechanism 20 and Figure 3B and Figure 3C The stacking mechanism 40 has the same structure, and the aforementioned fastening method can be understood by referring to the hand buckle 205 of the stacking mechanism 20 and the hand buckle 405 of the stacking mechanism 40. The stacking mechanism 20 also includes a hand buckle 205, wherein the hand buckle 205 specifically includes: a buckle protrusion 2051, a buckle fixing end 2052, a buckle operating end 2053 and a buckle deformation end 2054. The buckle fixing end 2052, the buckle deforming end 2054 and the buckle operating end 2053 are connected in sequence, the buckle protrusion 2051 is set on the buckle deforming end 2054, the buckle fixing end 2052 is fixed to the inner side surface of the stacking end 202 (the side facing the infusion pump host), and the buckle operating end 2053 is set outside the stacking end 202. When the buckle operating end 2053 is subjected to force alone, the buckle deforming end 2054 is deformed and drives the buckle protrusion 2051 away from the through hole 2021 of the stacking end 202; when the buckle operating end 2053 is not subjected to force, the buckle protrusion 2051 is set in the through hole 2021 of the stacking end 202. The portable buckle is simple and easy to use. At the same time, a first recess 105 is also provided on the surface where the second shell slot 102 of the infusion pump host 10 is located. When the second shell slot 102 of the infusion pump host 10 is connected to the stacking end 402 of the stacking mechanism 40, the buckle protrusion 4051 passes through the through hole 4021 of the stacking mechanism 40 and then snaps into the first recess 105, thereby realizing reinforcement between the infusion pump host 10 and the stacking end 402.

[0046] In some embodiments, such as Figure 6As shown, two mounting holes are provided on the buckle fixing end 2052, and two mounting holes are also provided near the first recess on the inner side of the stacking mechanism 20. The mounting holes of the buckle fixing end 2052 are connected to the mounting holes near the first recess 105 on the inner side of the stacking mechanism 20 by screws 2055, so that the buckle fixing end 2052 of the hand buckle 205 remains unchanged when the user operates the buckle operating end 2053.

[0047] In some embodiments, such as Figure 6 As shown, a notch 2022 is further provided in the stacking mechanism 20 to facilitate the pressing operation of the buckle operating end 2053, and also to limit the buckle operating end 2053 to ensure that the buckle deformation end 2054 will not be damaged by excessive pressing.

[0048] In some embodiments, such as Figure 7A-7B As shown, a gripping ridge 207 is provided at the upper edge of the stacking end 202, and the user can use the gripping ridge 207 to facilitate the user to hold and exert force when lifting the infusion pump host or multiple infusion pump hosts. Specifically, it can be semicircular, which provides a good hand holding experience; of course, it can also be other shapes.

[0049] In some embodiments, such as Fig. 12B As shown, the infusion pump is also used in conjunction with a fastening clip 50, and the infusion pump host 10 can be fixed on an external mounting platform (e.g., a column of a pendant) by means of the fastening clip 50. Therefore, the outer side of the stacking mechanism 20 also includes a handle slot 209, for example, the handle slot 209 can be set in the height extension end 203, or can be set on the outer side of the fixed end 201 or the stacking end 202. The fastening clip 50 is clamped in the handle slot 209 to achieve the connection between the fastening clip 50 and the infusion pump host 10, and the infusion pump host 10 can be fixed to the external mounting platform by means of the fastening clip 50. The handle slot 209 is used to limit the relative position of the fastening clip 50 and the stacking mechanism 20.

[0050] In some embodiments, the infusion pump is used in conjunction with the fastening clip 30, and a third housing card slot 103 is provided on the infusion pump host. Fig.11A As shown, for example, the third shell slot 103 can be set on the back of the infusion pump host 10; of course, the third shell slot can also be set on the side of the infusion pump host, and the third shell slot can also be set on the back and side of the infusion pump host at the same time; the fastening clip 50 is connected to the third shell slot 103, so as to realize the connection between the infusion pump host 10 and the fastening clip 50, and through the fastening clip 50, the infusion pump host 10 can be fixed to the external mounting platform 70 (for example, the column of the pendant).

[0051] In some embodiments, the infusion pump is used in conjunction with a fastening clip and a fixing plate. The infusion pump host can be connected to the fixing plate and then connected to the fastening clip through the fixing plate. One side of the fixing plate 60 can be engaged with the first housing card slot 101 or the second housing card slot 102 on the infusion pump host 10, and the other side of the fixing plate 60 can be engaged with the fastening clip 50 ( Fig.11A Of course, one side of the fixing plate can be connected to the second housing slot on the infusion pump host, and the other side of the fixing plate can be connected to the fastening clip. In the case where the infusion pump host is provided with a third housing slot, one side of the fixing plate can be connected to the third housing slot on the infusion pump alone, and the other side of the fixing plate can be connected to the fastening clip. It can also be, as Fig.11A As shown, one side of the fixing plate 60 can be engaged with the first housing slot 101 on the infusion pump host 10, and the other side of the fixing plate 60 can be engaged with the third housing slot 103 and the fastening clip 50. Alternatively, one side of the fixing plate can be engaged with the second housing slot 102 on the infusion pump, and the other side of the fixing plate can be engaged with the third housing slot 103 and the fastening clip 50. By setting the fixing plate, the fastening clip can be flexibly connected to the infusion pump host, enriching the connection method between the fastening clip and the infusion pump host, and can be applied to various scenarios.

[0052] In some embodiments, when a stacking mechanism is connected to the infusion pump host, one side of the fixing plate can be engaged with the handle slot, and the other side of the fixing plate can be engaged with the fastening clip. By setting the fixing plate, the fastening clip can be flexibly connected to the infusion pump host, enriching the connection methods of the fastening clip and the infusion pump host, and can be applied to various scenarios.

[0053] In some of these examples, see Figures 10A-10DThe fastening clamp 50 includes a clamp block 503, a base 501 and a screw 502, wherein the base 501 includes a first fastening surface 5011, a second fastening surface 5012 and a mounting surface 5013; the screw 502 includes a screw handle 5021, a screw body 5022 and a clamp block 5023 connected in sequence; the clamp block 503 is arranged on the mounting surface 5013, a screw through hole is opened on the first fastening surface 5011, and the screw handle 5021 is arranged on the mounting surface 5013. On the outside of the first fastening surface 5011, the fastening block 5023 is arranged between the first fastening surface 5011 and the second fastening surface 5012. Under the action of external force, the screw handle 5021, the screw body 5022 passes through the screw through hole 5015, and drives the fastening block 5023 to move in the direction of the second fastening surface 5012, or drives the fastening block 5023 to move in the opposite direction of the second fastening surface 5012, so as to adapt to the clamping and loosening of the fastening clamp 50. When the infusion pump host 10 is provided with a third shell slot 103, the clamping rib block 503 can be clamped with the third shell slot 103; when the infusion pump host 10 is provided with a stacking mechanism 20, it can also be clamped with the handle clamping slot 209 in the stacking mechanism 20; when a fixing plate 60 is provided, it can also be clamped with one side of the fixing plate 60, and then through the other side of the fixing plate 60 with the first shell slot 101, the second shell slot 102 or the third shell slot 103 in the infusion pump host 10, and of course, it can also be clamped with the handle clamping slot 209 of the stacking mechanism 20 through the other side of the fixing plate 60.

[0054] In some of these examples, see Figures 10A-10D The second fastening surface 5012 may be provided with a groove 5014 that matches the external mounting platform to enhance the installation stability of the fastening clip 50 and the external mounting platform without causing rotation.

[0055] In some of these examples, see Figures 10A-10D In order to adapt to the shape of the external mounting platform, the fastening clamp 50 may be provided with a screw hole platform 5031 at the center of the clamp block 503, and the mounting surface 5013 may be provided with a screw hole 5016 accordingly. The screw hole platform 5031 and the screw hole 5016 may be connected by screws 506, thereby realizing the connection between the clamp block 503 and the base 501. Among them, the screw hole 5016 of the mounting surface 5013 may be set to a "cross shape", and the screw hole platform 5031 of the clamp block 503 is a "one" shape. The screw hole platform 5031 may be fixed to the screw hole 5016 by screws in a vertical direction or in a horizontal direction, so as to facilitate the installation environment of various external mounting platforms.

[0056] In some embodiments, the clamp block and the mounting surface can be set to rotate and assemble, and the mounting surface can be placed horizontally or vertically relative to the clamp block, and can also be adapted to different mounting platforms; for example, the clamp block is inserted into the screw hole of the mounting surface, or it can be rotated 90 degrees clockwise and inserted into the mounting surface, and then fixed by screws. In another case, the clamp block and the mounting surface are still fixedly connected, but the clamp block can be connected to the handle slot in the horizontal direction or in the vertical direction, and the fastening clamp can also be adapted to different mounting platforms.

[0057] In some embodiments, such as Figures 10A-10D As shown, the screw hole platform 5031 is in the shape of a boss and is arranged on the clamping rib block 503. Through the combination of the boss and the screw hole in the mounting surface 5013, the connection between the clamping rib block 503 and the base 501 is made more stable.

[0058] In some embodiments, such as Figures 10A-10D As shown, the fastening clip 50 further includes a ball plunger 504, which is disposed in the clamp block 503 and can move relative to the clamp block 503 under the action of an external force. In the absence of an external force, the ball plunger 504 protrudes a certain distance from the outer surface of the clamp block 503. Correspondingly, the first housing clamping slot 101, the second housing clamping slot 102 or the third housing clamping slot 103 is provided with a second recess 106, and a corresponding recess may also be provided in the fixing plate 60 or the handle clamping slot 209. Therefore, when the clamp block 503 is engaged with one of the first shell slot, the second shell slot, the third shell slot, the fixed plate or the handle slot, the ball plunger 504 moves toward the mounting surface 5013 under the action of the extrusion external force, so that the clamp block 503 is smoothly engaged into the first shell slot, the second shell slot, the third shell slot, the fixed plate or the handle slot; when the clamp block 503 is engaged, the ball plunger 504 is acted upon by its built-in spring and moves outward, so that the ball plunger 504 is engaged in the second recess 106 or the groove at the corresponding position on the fixed plate or the groove at the corresponding position of the stacking mechanism, so as to ensure the connection between the fastening clamp 50 and the infusion pump host 10.

[0059] In some embodiments, in order to make the fastening clip 50 more firmly connected to one of the first shell card slot, the second shell card slot, the third shell card slot, the fixing plate or the handle card slot, a fastening clip buckle 208 is provided at one of the first shell card slot, the second shell card slot, the third shell card slot, the fixing plate or the handle card slot, wherein Figure 6The fastening clip buckle 208 is provided at the side of the handle slot. The fastening clip buckle 208 includes a buckle hook 2082 and a buckle handle 2084; the clamp block 503 on the fastening clip 50 is further provided with a clamp notch 5032. One end of the buckle handle 2084 is connected to the buckle hook 2082, and the other end of the buckle hook 2082 is connected to the clamp notch 5032. Under the action of external force, the buckle handle 2084 drives the buckle hook 2082 to move, so that the buckle hook 2082 is connected to or separated from the clamp notch 5032.

[0060] In some embodiments, the fastening clip buckle 208 further includes an elastic member 2083, one end of the elastic member 2083 can be connected to the stacking mechanism 20 or the fixing plate 60, and the other end of the elastic member 2083 abuts against the buckle handle 2084. Figure 6 As shown, one end of the elastic member 2083 can also abut against the shell 2081 of the fastening clip buckle 208, and the shell 2081 of the fastening clip buckle 208 is connected to the first shell slot, the second shell slot, the third shell slot, the fixing plate or the stacking mechanism by screws, or the shell 2081 can be fixedly connected or integrally formed with the first shell slot, the second shell slot, the third shell slot, the fixing plate or the outer shell of the stacking mechanism itself, wherein a protrusion is provided in the fastening clip buckle shell 2081 to fix one end of the elastic member 2083, and the fastening clip buckle shell 2081 also limits the buckle handle 2084, so that the buckle handle 2084 can only move in one direction, for example Figure 6 When the buckle handle 2084 is acted upon by an external force, the buckle handle 2084 drives the buckle hook 2082 away from the rib notch 5032 and compresses the elastic member 2083; when the buckle handle 2084 is not acted upon by an external force, the elastic member 2083 pushes the buckle handle 2084 to move toward the rib notch 5032 so that the buckle hook 2082 abuts against the rib notch 5032, which utilizes the restoring force of the elastic member 2083 to keep the buckle hook 2082 in the fastening clip buckle 208 tightly connected with the rib notch 5032 on the fastening clip 50.

[0061] In some embodiments, such as Figures 10A-10D As shown, the clamp block 503 is square, and each side of the clamp block 503 is provided with a clamp notch 5032. The shape of the clamp notch 5032 is coupled with the shape of the buckle hook 2082 in the stacking mechanism 20. When the fastening clip 50 is connected and fixed to the infusion pump host 10 in various directions, the fastening clip buckle 208 can be used to reinforce the fastening clip 50 in each direction, and the adaptability is stronger.

[0062] In some of these examples, see Figures 11A-11CThe fixing plate 60 includes a fixing plate clamping end 601, a fixing plate clamping slot 602 and a fixing plate screw 603. The fixing plate is clamped to the first housing clamping slot or the second housing clamping slot through the fixing plate clamping end; of course, in the case where a third housing clamping slot or a handle clamping slot is provided, the fixing plate can also be clamped to the third housing clamping slot or the handle clamping slot if necessary, so that the fixing plate is connected to the infusion pump host. Figures 11A-11C It is shown that: the user can operate the fixing plate screw 603, pass through the mounting hole set on the fixing plate clamping end 601, and connect with the first host mounting hole 104 in the first shell clamping slot 101 of the infusion pump host 10, so that the fixing plate 60 clamped in the first shell clamping slot 101 is connected to the infusion pump host 10; when the fixing plate clamping end 601 is clamped with the first shell clamping slot 101, the fixing plate clamping slot 602 of the fixing plate 60 can be located in the third shell clamping slot 103 of the infusion pump host 10, that is, the shape of the third shell clamping slot 103 is coupled with the shape of the fixing plate clamping slot 402, and the fixing plate 60 is connected to the clamping rib block 503 in the fastening clamp 50 through the fixing plate clamping slot 602. A through hole matching the ball plunger 504 can also be provided in the fixing plate slot 602, so that when the rib block 503 is engaged with the fixing plate slot 602, the ball plunger 504 can pass through the through hole to connect with the second recess 106 in the infusion pump host 10, so as to realize the connection stability between the fixing plate 60 and the infusion pump host 10. In the case where the rib block is engaged with the handle slot, a through hole can also be provided in the handle slot so that the ball plunger can be engaged with the second recess through the through hole. In the case where the rib block is directly engaged with the third housing slot of the infusion pump host, the ball plunger is directly engaged with the second recess. Among them, the plane where the fixing plate engaging end 601 is located can be perpendicular to the plane where the fixing plate slot 602 is located, so as to realize fixed connection with the infusion pump host on two sides, which is more firm; when there is an installation requirement, the fastening clip can be installed on the bottom surface or back surface of the infusion pump host through the conversion of the fixing plate, which has high adaptability.

[0063] In some embodiments, such as Figures 12A-12BThe infusion pump system shown can be directly lifted by the stacking mechanism. The infusion pump system includes a first infusion pump host (infusion pump host 10) and a second infusion pump host (infusion pump host 30), and also includes a first stacking mechanism 20 corresponding to the first infusion pump host, and a second stacking mechanism 40 corresponding to the second infusion pump host, wherein the fixed end 201 of the first stacking mechanism 20 is connected to the first shell card slot 101 of the first infusion pump host 10, the stacking end 402 of the second stacking mechanism 40 is connected to the second shell card slot 102 of the first infusion pump host 10, and the fixed end 401 of the second stacking mechanism 40 is connected to the first shell card slot 301 of the second infusion pump host 30, so that the first infusion pump host 10 and the second infusion pump host 30 are connected to each other through the cooperation of the first stacking mechanism 20 and the second stacking mechanism 40, and the stacking end 202 of the first stacking mechanism 20 can directly apply force to lift the entire infusion pump system. Of course, the infusion pump system can also include other infusion pump hosts with the same structure as the infusion pump host 10 / 30, and their matching stacking mechanisms 20 / 40 according to the needs of infusion. The infusion pump system can also be used in conjunction with at least one fastening clip 50, which can be engaged with the third shell slot located in the infusion pump host to achieve a fixed connection between the entire infusion pump system and the external mounting platform 70. The infusion pump system can also be used in conjunction with at least one fastening clip 50 and at least one fixing plate 60, which can be fixed to the handle slot 209 of the stacking mechanism in the infusion pump host, or the first shell slot or the second shell slot through the fixing plate 60, which is flexible and changeable. In summary, the above-mentioned infusion pump system is used in conjunction with the stacking mechanism to achieve connection between the infusion pump hosts, and is convenient for moving multiple infusion pump hosts as a whole. In addition, the entire process is easy to install, which improves the user's convenience. By providing a first shell card slot and a second shell card slot on the bottom and / or back of the infusion pump host, the stacking mechanism is also connected to the infusion pump host, which is beneficial to protecting the overall appearance of the infusion pump host and is convenient for cleaning.

[0064] In some embodiments, such as Figures 12A-12B It may further include a third infusion pump host 70 and a third stacking mechanism 80 used in conjunction with it. The matching relationship between them is the same as the matching relationship between the first and second infusion pump hosts and the first and second stacking mechanisms, and can refer to the above embodiment.

[0065] In some embodiments, stacking is performed only by a stacking mechanism, and the lifting function is realized by another portable part. The infusion pump system specifically includes a first infusion pump host (infusion pump host 10), a second infusion pump host (infusion pump host 30) and a third infusion pump host (infusion pump host 70), and also includes a stacking mechanism 40 / 80 and a portable part 210, wherein the stacking mechanism and the portable part are independent of each other. The stacking mechanism 40 / 80 is connected with the infusion pump host 10, 30 and 70, so that the stacking mechanism 40 / 80 and the infusion pump host 10, 30 and 70 form an infusion pump system, and the user can move the infusion pump system by holding the portable part 210. The portable part can be set on the top surface, side surface, bottom surface and back surface of one of the infusion pump hosts, preferably the bottom surface and back surface, which is conducive to cleaning. The portable part can be set in a convenient position for lifting according to the center of gravity distribution to avoid tilting of the infusion pump system. In this embodiment, the infusion pump host 10 and the infusion pump host 30 may have the same structure; or they may be different, for example, the infusion pump host 10 is only provided with the second shell card slot, and the infusion pump host 30 is only provided with the first shell card slot.

[0066] In some of these examples, see Fig. 12C The infusion pump system specifically includes a first infusion pump host (infusion pump host 10), a second infusion pump host (infusion pump host 30) and a third infusion pump host (infusion pump host 70), and also includes a stacking mechanism 40 / 80 and a handheld part 210. The stacking mechanism 40 / 80 includes a stacking end 402 / 802 and a fixed end 401 / 801, wherein the handheld part 201 and the stacking mechanism are independent of each other. The fixed end 401 in the stacking mechanism 40 is connected to the first housing card slot 301 of the infusion pump host 30, and the stacking end 402 is connected to the second housing card slot 102 of the infusion pump host 10; the fixed end 801 is connected to the first housing card slot 701 of the infusion pump host 70, and the stacking end 802 is connected to the second housing card slot 302 of the infusion pump host 30; the handheld part 210 is connected to the third housing card slot 103 of the infusion pump host 10 or to the handheld part card slot of the infusion pump host 30. The stacking mechanism 40 / 70 and the infusion pump host 10, 30 and 70 form an infusion pump system, and the user can move the infusion pump system by holding the hand-held part 210. In an optional implementation, the connection relationship between the stacking mechanism 40 / 70 and the infusion pump host 10, 30 and 70 is as follows: Fig.12D As shown. On the premise of ensuring that there is sufficient space at the handle part for the user to hold and grasp, the effect of reducing the interval between the infusion pump host and the hand-held part is achieved when the infusion pump host is connected.

[0067] In some embodiments, such as Figures 9A-9DThe infusion pump shown in the figure is used only with the fastening clip to fix the infusion pump host to the external mounting platform. Fig.9A The third housing slot 103 is provided on the side (not shown), and the third housing slot 103 is connected to the fastening clip 50. The infusion pump host is fixedly connected to the external mounting platform 70 through the fastening clip 50. When the external mounting platform 70 is a vertical rod, such as Fig. 11C As shown, the clamp block 503 in the fastening clamp 50 can be connected to the infusion pump host 10 by clamping the third housing clamping slot 103 of the infusion pump host 10. When the clamp block 503 is completely clamped into the third housing clamping slot 103, the infusion pump host 10 and the fastening clamp 50 are connected. Figures 9A-9D , Figures 9A-9D Schematic diagram of the connection between an infusion pump host 10 and a fastening clamp 50 provided in an embodiment of the present application. When the external mounting platform 70 is a crossbar: Figure 9C-9D As shown, when the external mounting platform 70 is a vertical pole: Figures 9A-9B As shown. The clamp block 503 of the fastening clip 50 can be connected to the infusion pump host 10 by clamping the third housing clamping slot 103 of the infusion pump host 10. When the clamp block 503 is completely clamped into the third housing clamping slot 103, the infusion pump host 10 is connected to the fastening clip 50. As for the specific structure and installation and use of the fastening clip, reference can be made to the description in the above other embodiments.

[0068] The fastening clamp in at least some of the above embodiments can fix the infusion pump host to the external mounting platform at various angles (such as horizontally or vertically) to adapt to the requirements of the external mounting platform.

[0069] At least some of the above embodiments further provide a fixing plate 60 to realize the conversion requirements between the infusion pump host 10 and the fastening clamp 50. One end of the fixing plate 60 can be connected to the first shell slot or the second shell slot at the bottom of the infusion pump host, and the other end can be connected to the fastening clamp 50, thereby meeting the connection requirements of the infusion pump host and the fastening clamp, and having wider adaptability.

[0070] In at least some of the above embodiments, the connection between the fastening clip 50 and the infusion pump host 10 can also be achieved by providing a handle slot in the stacking mechanism 20, so that the fastening clip 50 is connected to the infusion pump host 10 by snapping into the handle slot 209.

[0071] In short, in the first case, the stacking mechanism takes into account the hand-held function. The infusion pump can be used in conjunction with the stacking mechanism. It only needs to insert the stacking mechanism from the back of the infusion pump host to complete the assembly of the infusion pump host and the stacking mechanism. It is simple and quick. It can be convenient to lift the infusion pump host. When multiple infusion pump hosts are needed for combined use, there is no need to disassemble the stacking mechanism. Through the cooperation of the card slot structure of multiple stacking mechanisms and multiple infusion pump hosts, the combination can be quickly realized, and the lifting problem after combined use is also realized simultaneously. Specifically, the infusion pump host can be assembled with its matching stacking mechanism, and then the infusion pump host assembled with the stacking mechanism can be inserted from the bottom with other infusion pump hosts assembled with the stacking mechanism to complete the stacking of multiple infusion pump hosts. It is simple and quick. Especially for patients in critically ill wards, this method does not need to set a fixed handle in the infusion pump, thereby saving space; at the same time, the stacking mechanism is also easy to plug and unplug with the infusion pump host, so that the infusion pump host can be placed in the dock after the stacking mechanism is removed. In addition, it is also considered that the infusion pump host is used alone or in combination. After being moved, it may need to be fixed on a set external mounting platform. There is no need to disassemble or adjust the assembled portable structure. The fastening clip can be directly connected to the stacking mechanism or connected to the stacking mechanism through a fixed plate. The connection between the fastening clip and the infusion pump host is convenient and quick, which is convenient for users to use. When critically ill patients are monitored or treated by equipment to maintain life, a medical cart will be parked next to the patient. Monitors or other equipment are generally placed on the cart, and the infusion pump can be fixed to the vertical pole of the cart by a fastening clip. The fastening clip design of this solution can make the fastening clip and the infusion pump host easy to disassemble, so that the infusion pump can be removed and placed in the dock. The use requirements of the infusion pump in multiple usage scenarios can be very flexibly met. It is easy to install, disassemble, and fix.

[0072] In the second case, when the stacking mechanism is only used to connect the infusion pump host with other infusion pump hosts, it can be easily disassembled and assembled, and the card slots are all set on the bottom or back of the infusion pump host, so that the overall appearance of the infusion pump host is not damaged and is easy to clean or disinfect; when it is necessary to lift it, the external carrying parts can be easily installed to realize the mobile function, which is convenient and easy to use.

[0073] When the infusion pump is used alone with the fastening clamp, the fastening clamp can be connected and reinforced to the infusion pump host by simple methods such as snap-on and ball plunger, without the need for tools, which is convenient and quick; if the card slot setting of the infusion pump does not meet the installation requirements, it can also be converted with the help of a fixing plate, which is highly flexible.

[0074] For the infusion pump host only, the multiple card slots at the bottom and / or side can meet the user's mobility needs, as well as the fastening needs, and can also be applied to various transformation scenarios. And the reinforcement form considered is compact and easy to use.
