Embodiments of the present application are described in detail below.

Referring to fig. 1, a flowchart illustrating steps of a method for controlling an infusion pump according to an embodiment of the application is shown. The infusion pump control method comprises the following steps:

At step 100, a medication name setting event is detected.

In this embodiment, the infusion pump 100 (shown in fig. 5) is used with an infusion set, wherein the infusion pump 100 includes the syringe pump 10 (shown in fig. 2) and the infusion pump 20 (shown in fig. 3), the syringe pump 10 is used with the syringe 60 (shown in fig. 6), and the infusion pump 20 is used with the infusion tube 40 (shown in fig. 4).

Referring to fig. 2, a schematic diagram of a syringe pump according to an embodiment of the application is shown. The syringe pump 10 includes a pump main body 110, a pump door 112 rotatably provided to the pump main body 110, a grip mechanism 118 provided to the pump main body 110, a housing groove 116 provided at one side end of the pump main body 110, and a push-pull mechanism 114 provided at the side end where the housing groove 116 is provided and movable in a predetermined direction (infusion direction or infusion opposite direction) under the belt of a driving mechanism 133 (shown in fig. 9).

Referring to fig. 3, a schematic diagram of an infusion pump according to an embodiment of the application is shown. The infusion pump 20 includes a pump body 201, a display system 205, a peristaltic compression mechanism 200 (shown in fig. 4), and a pump door 207, with the pump door 207 being movably mounted to the pump body 201 to conceal the receiving chamber 216 for mounting the infusion tube 40, and sometimes the receiving chamber 216 for mounting the infusion tube 40 may be exposed when the user opens the pump door 207. The pump door 207 has a front face facing the user (exterior) and side faces that can be used to mate with the mounting bracket, as well as top and bottom faces that can be used opposite other infusion pumps in a stacked arrangement. The display system 205 is disposed on the pump door 207, and the display system 205 extends from the left side of the front center line of the pump door 207 to the right side of the front center line of the pump door, and the width of the display system 205 is greater than the height thereof, and the display system 205 is disposed on the pump door in an overall strip shape.

In some embodiments, the width of the display system 205 is greater than or equal to 70% of the width of the front face of the pump door 207, the height of the display system 205 is greater than or equal to 60% of the height of the front face of the pump door 207, or the area of the display system 205 is greater than or equal to 2/3 of the area of the front face of the pump door 207. When the pump door 207 exhibits a lateral dimension greater than a longitudinal dimension, i.e., a width greater than a height, the width of the display system 205 is greater than the height thereof, thereby allowing a larger display area and rendering the display system 205 rectangular in lateral length. Wherein the pump door 207 is further provided with physical input keys 203 arranged on one side of the display system, for example the physical input keys 203 may be partly or wholly on the right, upper, lower or left side of the display system. The user may input data or instructions through the physical input keys 203. When the display screen of the display system 205 is a touch screen, the user may also input data or instructions through the touch screen. Of course, the setting of the physical input key 203 can be used in emergency, and when the touch screen fails and infusion control cannot be performed, the user can perform infusion control through the physical input key 203, so as to ensure the use safety of the infusion pump. In one embodiment, the syringe pump 10 may also include a display system as in the infusion pump 20.

In some embodiments, the display system 205 includes more than two display screens, at least one of which is formed by stacking a touch layer and a display layer, and the other display screens may be formed by only the display layer. Of course, in order to achieve a better touch effect for the user, the display system 205 includes a display screen formed by laminating a touch layer and a display layer.

Referring to fig. 4, a schematic layout of the peristaltic squeezing mechanism and the infusion tube according to an embodiment of the application is shown. Peristaltic compression mechanism 200 includes a cam shaft 202, a pump stack 204, and a compression plate 206. The processor in the infusion pump 20 sends out instructions such as rotation speed or position, and the power driving circuit 130 (shown in fig. 5) drives the power equipment 208 (such as a motor) to work according to the designated rotation speed and rotation direction, and the power equipment (or driving mechanism) 208 drives the cam shaft 202 connected with the power equipment to rotate in the rotation process; during rotation of the cam shaft 202, the pump vane set 204 on the cam shaft 202 performs linear reciprocating motion, that is, the pump vanes on the pump vane set 204 sequentially perform linear reciprocating motion. The pump blade set 204 cooperates with the squeeze plate 206 to sequentially squeeze and release the outer wall of the infusion tube 40 in a reciprocating manner, thereby forcing the fluid in the infusion tube 40 to continue to flow in a directional manner. A speed reducing mechanism may be further disposed between the power device 208 and the cam shaft 202 to ensure that the rotational speed of the pump vane set 204 is stable and uniform.

In this embodiment, the infusion pump 100 may operate in an infusion preparation phase or a priming phase. For infusion pumps, preparation for an infusion operation includes positioning syringe 60 within syringe pump 10, upon detection of a confirmation event that syringe 60 is positioned within syringe pump 10, syringe pump 10 controls push-pull mechanism 114 to move toward plunger stem 606 of syringe 60, and upon contact of push-pull mechanism 114 with plunger stem 606 of syringe 60 (shown in fig. 6) and receipt of an infusion operation initiation command, syringe pump 10 enters an initiation infusion operation phase; during the priming phase of the infusion operation, the syringe pump 10 controls the movement of fluid within the syringe 60 in the infusion direction in accordance with the set infusion parameter (e.g., flow rate) setting. For a syringe pump, preparation for an infusion operation includes placing the infusion tube 40 within the receiving chamber 216 of the infusion pump 20, and upon detecting an in-place condition of the infusion tube 40 being placed within the infusion pump 20, a user may perform an input operation, such as sending an infusion operation initiation command, setting infusion parameters, within the display system 205. After the infusion operation start instruction, the infusion pump 20 enters a start infusion operation phase; during the priming phase of the infusion operation, the infusion pump 20 controls movement of the peristaltic compression mechanism 200 in accordance with a set infusion parameter (e.g., flow rate) to cause fluid within the infusion tube 40 to move in the infusion direction.

Some or all of the visual output may correspond to user interface objects, further details of which will be described herein.

The touch screen also accepts user input based on haptic sensation and/or contact. The touch screen forms a touch sensitive surface that receives user input. The touch screen and display controller 140 (along with any associated modules and/or sets of instructions in the memory 104) detects contact on the touch screen (and any movement or disruption of the touch) and converts the detected contact into interaction with user interface objects, such as one or more soft keys, displayed on the touch screen.

In some embodiments, the control platform 102 may sense whether the infusion tube 40 is mounted on the receiving chamber 216 via the position sensor 164. If the position sensor 164 detects that the tube wall of the infusion tube 40 is not in contact with the accommodating cavity 216 within the detection range of the position sensor 164, the control platform 102 drives the liquid stopping clamp to open, so that the liquid stopping clamp releases the infusion tube 40. Specifically, a front end detection device is disposed in the infusion pump 20, where the front end detection device may include one or two or more position sensors 164. For example, when a position sensor is provided at a location of the receiving chamber 216 of the infusion pump 20, the processor of the infusion pump 20 determines that the infusion tube 40 is disposed within the infusion pump 20 if it detects that the position sensor at the location transmits a feedback signal; when a position sensor is disposed at the first target location of the receiving chamber 216 and a position sensor is disposed at the second target location, such that both position sensors detect and transmit feedback information, it is determined that the infusion tube 40 is disposed within the infusion pump 20; when at least one position sensor 164 detects that the wall of the infusion tube 40 is not in contact with the receiving chamber 216, the control platform 102 may then actuate the stopper clamp open. The receiving chamber 216 is defined within the infusion pump where the infusion set is mounted.

The displacement sensor 166 may respond to changes in the position of the object under test relative to a reference position and convert the changes in position into an electrical signal that can be detected and sent to the control platform 102 via the I/O system 108. The displacement sensor 106 may be inductive, capacitive, ultrasonic, or hall.

The light assembly 168 may include a visual alarm element for indicating that the infusion pump 100 is in an abnormal condition. The light assembly 168 is solely responsive to actuation of the processor/controller 150; the light assembly 168 may also be correspondingly coupled to the speaker 154 in response to actuation of the processor/controller 150, such as a color or brightness change of the light with the tone, frequency of the alarm sound. The light assembly 168 may include an indicator light for a power source, CPU, etc., or an infusion fault condition alarm light. The light assembly 168 may also include a visual illumination element for facilitating viewing of the structure or assembly status of the infusion pump 100 in the event of poor ambient light.

The infusion pump 100 also includes a power supply system 106 for powering the various components.

In one embodiment, the touch module 174 may selectively detect contact with the display 160 or other touch sensitive device (e.g., touch buttons, touch pad). For example, the touch module 174 detects contact with the display screen 160 along with the display controller 140. The touch module 174 includes various software components for performing various operations associated with detection of contact (which may be by a finger or stylus, etc.) with the display screen 160, such as determining whether contact has occurred (e.g., detecting a finger press time), determining the strength of the contact (e.g., the force or pressure of the contact), determining whether the contact has moved (e.g., detecting one or more finger drag events), or tracking movement on the display screen and determining whether the contact has stopped (e.g., detecting a finger lift time or contact disconnection). Wherein determining movement of the point of contact may include determining a velocity (amplitude), a speed (amplitude and direction), and/or an acceleration (including amplitude and/or direction) of the point of contact. These operations may be applied to single point contacts or simultaneous multiple point contacts. In one embodiment, the touch module 174, in conjunction with the display controller 140, detects contact by other touch devices.

The touch module 174 may be used to detect gesture inputs of a user. Different gestures of the user on the touch-sensitive device have different contact patterns (e.g., one or more combinations of location, time, or intensity of detected contacts). For example, detecting a single-finger flick gesture includes detecting a finger-down event and then detecting a finger-up event at the same or a similar location as the finger-down event. For example, detecting a finger swipe gesture on a surface of a touch device includes detecting a finger press event, then monitoring for one or more finger drag events, and then detecting a finger lift event. Similarly, taps, swipes, drags, and other gestures of the stylus are optionally detected by detecting a particular contact pattern of the stylus.

Haptic feedback module 176 includes various software components for generating instructions to generate haptic output at one or more locations of syringe pump 10 using one or more haptic output generators (not shown) in response to user interaction with syringe pump 10. For example, upon detection of contact with the surface of the touch device, the color of the graphics or text of the touch device changes, or sounds or vibrations are produced.

Referring to fig. 6, a schematic diagram of a syringe disposed in a syringe pump according to an embodiment of the application is shown. The push-pull mechanism 114 includes a connecting rod 1142 and a pushing block 1140, the pushing block 1140 is fixed at one end of the connecting rod 1142, the connecting rod 1142 is connected to the pump body 110 in an axial sliding manner, and the push-pull mechanism 114 is driven by the driving mechanism 133 to move along the axial direction of the connecting rod 1142. The grip mechanism 118 is rotatably disposed on the pump body 112, and the grip mechanism 118 is switchable between a first state and a second state under a rotational operation of a user. The grip mechanism 118 is located within a receiving cavity of the syringe pump 10 for receiving the syringe 60. Prior to setting syringe 60, the user may rotate grip mechanism 118 from the first state to the second state and pull push-pull mechanism 114 a preset length away from pump body 110 so that syringe pump 10 has sufficient space to set syringe 60.

In this embodiment, the syringe 60 includes a syringe body 602, a flange 604 disposed at one end of the syringe body 602, and a piston stem 606, wherein the syringe body 602 is hollow and is configured to accommodate the piston stem 606, and the piston stem 606 is movable in a radial direction of the syringe body 602. When the syringe 60 is disposed in the syringe pump 10, the user can rotate the grip mechanism 118 to the second state to press-fit the syringe body 602 onto the pump body 110 of the syringe pump, the flange 604 of the syringe 60 is received in the receiving groove 116 of the pump body 110, and the distance between the piston handle 606 and the pushing block 1140 is a predetermined distance d (shown in fig. 7).

In this embodiment, the pump door 112 may have a position sensor 164 disposed therein, and the processor 150 determines the status of the pump door 112 through the position sensor disposed in the pump door 112, wherein the status of the pump door 112 includes an open status and a closed status. As shown in fig. 6, the processor 150 may determine that the pump door 112 is in an open state by being provided to a position sensor. Referring to fig. 7, a schematic diagram of a pump door of a syringe pump in a closed state according to an embodiment of the application is shown. As shown in fig. 7, the processor 150 may determine that the pump door 112 is in a closed state via a position sensor.

In this embodiment, the processor 150 obtains a confirmation event that the syringe 60 is disposed within the infusion pump 10 and determines that the medication name setting event is detected based on the confirmation event. For example, processor 150 may obtain a detection signal transmitted by a front end detection device provided on pump body 110 to determine that syringe 60 is disposed within syringe pump 10 and determine the confirmation event based on the detection signal. The front end detection device comprises a first position sensor and a second position sensor.

For example, a first position sensor is provided in the grip mechanism 118, and when the syringe 60 provided in the syringe pump 10 is press-fitted to the pump body 110 of the syringe pump 10, the grip mechanism 118 is in the second state, and at this time, the first position sensor can transmit a feedback signal. For example, when the syringe 60 is disposed within the syringe pump 10, the grip mechanism 118 secures the syringe body 602 to the pump body 110, and the first position sensor may output a feedback signal. In this manner, the processor 150 may obtain the feedback signal transmitted by the first position sensor to determine that the syringe body 602 of the syringe 60 is press-fit onto the pump body 110 of the syringe pump 10. In other embodiments, pressure sensors may be provided within the grip mechanism 118 or at corresponding locations on the pump body 110, i.e., when the syringe 60 is press-fit onto the pump body 110 of the syringe pump 10, the pressure sensors may contact the syringe 60, thereby generating a feedback signal with pressure information. The processor 150 may also determine whether to press fit the syringe 60 disposed within the syringe pump 10 onto the pump body 110 of the syringe pump 10 based on the received feedback signal having pressure information.

A second position sensor is disposed in the receiving groove 116. When the syringe 60 is set in the syringe pump 10, the flange 604 of the syringe 60 is received in the receiving groove 116, and at this time, the second position sensor may output a feedback signal. Thus, when the processor 150 receives the feedback signal from the second position sensor, the processor 150 can determine that the flange 604 of the syringe 60 is received in the receiving slot 116.

The processor 150 may detect the status of the pump door 112 based on sensors disposed within the pump door 112, and may also detect the disposed status of the syringe 60 based on the first and/or second position sensors. In one embodiment, the processor 150 receives at least one of the feedback signal transmitted by the first position sensor or the feedback signal transmitted by the second position sensor, and determines that a confirmation event is received that the syringe 60 is disposed within the infusion pump 10.

In one embodiment, when the first and second position sensors both transmit feedback signals to the processor 150, the processor 150 may determine that the syringe 60 is disposed in the syringe pump 10; when the processor 150 does not receive the feedback signal transmitted by either of the first position sensor and the second position sensor, the processor 150 may determine that the setting state of the syringe 60 is abnormal. For example, when the processor 150 receives the feedback signal transmitted by the first position sensor but does not receive the feedback signal transmitted by the second position sensor, it indicates that the flange 604 of the syringe 60 is not received in the receiving groove 116, and thus an abnormality in the installation state of the syringe 60 is detected; when the processor 150 receives the feedback signal transmitted by the second position sensor but not the feedback signal transmitted by the first position sensor, it indicates that the user has not turned to the grip mechanism 118 to the second state, and the grip mechanism 118 does not fix the syringe body 602 to the pump main body 110, so that the processor 150 can also detect that the setting state of the syringe 60 is abnormal. When the processor 150 determines that the setting status of the injector 60 is abnormal, the display screen or the display system 160 is controlled to output a prompt message of the abnormality of the setting status of the injector 60, and the processor 150 can also control the lamp light assembly 168 to output a prompt message of the abnormality of the setting status of the injector 60 through the lamp light controller 148.

In one embodiment, if the pump door 112 is in a closed state and the syringe 60 is not disposed in the syringe pump 10, the syringe pump 10 may be in a power-off state or a standby state, and if the user uses the syringe pump 10 to perform an infusion task of the syringe 60, the user needs to open the pump door 112 of the syringe pump 10. When the processor 150 detects that the pump door 112 is opened, the processor 150 controls the syringe pump 10 to be powered on or to perform a power-on operation, so that the syringe pump 10 is in a power-on state. During user set-up of syringe 60 (i.e., during the period of time processor 150 detects that pump door 112 is open to detect that pump door 112 is closed), syringe pump 10 may perform a self-test operation to detect the device status of syringe pump 10. Among other things, self-test operation of syringe pump 10 includes, but is not limited to, acoustic self-test, processor self-test, external storage device self-test, alarm lamp self-test, power supply self-test, and sensor self-test; the infusion pump 20 may also perform a pressure self-test operation. In performing the self-test of sound, the processor 150 may control the speaker 154 to make a sound through the audio circuit 124, and may determine whether the self-test of sound passes through the recording device; if the processor receives the sound from the speaker 154 via the audio recording device, it can determine that the self-test has passed, otherwise, it indicates that the device status of the syringe pump 10 is abnormal. When the processor self-checking is performed, the processor 150 may run a preset program in the memory 104, and determine whether a result obtained after running the preset program is a preset result; if the result obtained after the program to be preset is the preset result, the processor self-checking is determined to pass, otherwise, the device state of the injection pump 10 is abnormal. In addition, the processor 150 may also detect external storage devices, the light assembly 168, the power system 106, and a plurality of sensors. When each self-test operation is passed, it can be determined that the device state of the syringe pump 10 is normal; if at least one self-test operation fails, an abnormality in the device status of the syringe pump 10 is determined and a notification of the abnormality in the device status may be output via the display 160 or the light assembly 168. When the pressure self-checking operation is performed, the liquid stopping clamp can clamp the infusion tube 40 arranged in the accommodating cavity 216, control the peristaltic extrusion mechanism 200 to move in a preset direction, and determine whether the infusion tube 40 is normal according to the pressure value transmitted by the pressure sensor. For example, when the stopper is disposed in the accommodating chamber 216 and is close to the user end, if the peristaltic pressing mechanism 200 is controlled to move in the infusion direction, if the infusion tube 40 is normal, the pressure in the infusion tube 40 will be increased, and further, when the pressure value detected by the pressure sensor is increased, it is determined that the infusion tube 40 is normal; if the pressure sensor detects that the pressure value is reduced or unchanged, it is determined that the infusion tube 40 is abnormal, if there is an abnormality of breakage of the infusion tube, at this time, the infusion pump 20 can output a prompt message of the abnormality of the pressure of the infusion tube through the display screen 205.

Fig. 8 is a schematic diagram showing a state that the push-pull mechanism abuts against the piston handle according to an embodiment of the application. When the pump door 112 is closed and the syringe 60 is disposed within the syringe pump 10, the push block 1140 of the push-pull mechanism 114 has a predetermined distance d from the plunger stem 606, so the drive mechanism 133 needs to push the push block 1140 against (or in contact with) the plunger stem 606 after the predetermined distance d before the drive mechanism 133 controls the push-pull mechanism 114 to start the infusion operation.

The syringe pump 10 may include a power-on button 163 (including but not limited to a physical button or other type of button) that, when activated, a user may open the pump door 112 to place the syringe 60 in the syringe pump 10. Then, the syringe pump 10 also performs the self-checking operation during the process of setting the syringe 60 in the syringe pump 10, so as to achieve the purpose of reducing the time of the infusion task.

In an embodiment, a back end detection device, such as a pressure sensor, may be disposed on the pushing block 1140, so that when the pushing block 1140 blocks the piston stem 606, the pressure sensor disposed on the pushing block 1140 may output a feedback signal with pressure information to the processor 150, and further, when the processor 150 determines that the feedback signal transmitted by the pressure sensor disposed on the pushing block 1140 is received, the pushing block 1140 may be determined to abut against the piston stem 606. When the processor 150 receives the feedback signal transmitted by the first position sensor and/or the feedback signal transmitted by the front end detection device such as the second position sensor, and receives the feedback signal transmitted by the rear end detection device disposed on the pushing block 1140, the processor 150 can determine that the setting state of the syringe 60 disposed on the infusion pump 10 is normal.

Referring also to fig. 9, a schematic diagram of an infusion pump according to an embodiment of the application is shown, wherein the push-pull mechanism 114 is used to clamp the plunger stem 606 of the syringe 60. The processor 150 in the syringe pump 10 sends out instructions such as rotating speed or position, and the like, the power driving circuit 130 drives the power equipment (for example, the driving mechanism 133), the driving mechanism 133 drives the screw rod 135 and the screw nut 137 through the speed reducing mechanism, the rotating motion of the driving mechanism 133 is converted into the linear motion of the screw nut 137, the screw nut 137 is connected with the connecting rod 1142 of the syringe pump 10, the connecting rod 1142 is connected with the pushing block 1140, the pushing block 1140 can push the piston handle 606 of the matched syringe 60 to perform injection and transfusion, and the pushing speed of the matched syringe 60 can be adjusted through the rotating speed (such as the rotating speed of the second motor) of the driving mechanism 133, so that the given transfusion dosage and transfusion speed are adjusted.

Referring to fig. 10, a schematic diagram of an infusion parameter setting interface according to an embodiment of the application is shown. In this embodiment, when the processor 150 detects that the pump door 112 is closed and the injector 60 is disposed in the syringe pump 10, and receives feedback signals transmitted by the first position sensor and the second position sensor, the processor 150 can control the display screen 160 disposed on the pump door 112 to display the infusion parameter setting interface 510, wherein the infusion parameter setting interface 510 includes an infusion parameter setting item for presenting one or more infusion parameter contents including, but not limited to, infusion speed, flow rate unit, preset amount, preset time, infusion mode, consumable, medicine name, and the like. Wherein the infusion parameter settings may be edited based on user selections to adjust the infusion parameter content that they display. In one embodiment, when the processor of the infusion pump 20 detects that the pump door 207 is closed and the setting of the infusion set 40 disposed in the accommodating chamber 216 is normal, the processor of the infusion pump 20 may also control the display screen 205 disposed on the pump door 207 to display the infusion parameter setting interface 510, wherein the infusion parameter setting interface 510 includes an infusion parameter setting item for presenting one or more infusion parameter contents.

In this embodiment, the user may set the infusion parameter content at the infusion parameter setting interface 510. While the processor 150 controls the display screen 160 to display the infusion parameter setting interface 510, the processor 150 drives the driving mechanism 133 to act at the first motor rotation speed, drives the push-pull mechanism 114 to move in a direction towards the piston handle 606 of the syringe 60, and the driving mechanism 133 pushes the push-pull mechanism 114 against the piston handle 606 after acting at the first motor rotation speed for a preset time. Thus, the user controls the motion of the push-pull mechanism 114 while performing the infusion parameter set through the infusion parameter set interface 510, which is also beneficial to reducing the preparation time for the infusion operation. In one embodiment, the processor 150 may control the display screen 160 to display the infusion parameter setting interface 510 after receiving the feedback signal transmitted by the first position sensor and/or the feedback signal transmitted by the second position sensor, and receiving the feedback signal transmitted by the pressure sensor disposed on the pushing block 1140.

In this embodiment, the infusion parameter setting interface 510 includes a preset area 532 (such as the area where the "drug name" in fig. 10) related to the drug name, and when the preset area 532 is triggered (including but not limited to a gesture or operation triggered, which may be a single click, a double click, a sliding, etc.), the user generates a selection event, which indicates that the user sets the drug name of the infusion apparatus disposed in the infusion pump 100. As such, the processor 150, upon receiving the selection event, may determine that a drug name setting event is detected.

Step 102, controlling the display screen to display a drug name setting interface, wherein the drug name setting interface comprises a plurality of drug name options, the areas where different drug name options are located are mutually independent or partially overlapped, and the drug name options are used for presenting the drug names infused by the infusion pump.

Referring to fig. 11, a schematic diagram of a drug name selection item according to an embodiment of the application is shown. Upon detection of the medication name setting event, the processor 150 may control the display screen 160 to display a medication name setting interface 520. For example, upon receiving the feedback signal transmitted by the first position sensor and/or the feedback signal transmitted by the second position sensor, the processor 150 determines that a confirmation event is received that the syringe 60 or the infusion set 40 is disposed within the infusion pump 10 and controls the display screen 160 to display the medication name setting interface 520. For the syringe 60, after receiving the feedback signal transmitted by the first position sensor and/or the second position sensor, the processor 150 has a preset distance d between the pushing block 1140 of the push-pull mechanism 114 and the piston handle 606, so when the user operates in the displayed medicine name setting interface 520, the processor 150 can control the driving mechanism 133 to act at the first motor rotation speed, so as to drive the push-pull mechanism 114 to move towards the piston handle 606 of the syringe 60, and the driving mechanism 133 pushes the push-pull mechanism 114 against the piston handle 606 after acting at the first motor rotation speed for a preset time. The user controls the motion of the push-pull mechanism 114 while selecting a drug name through the drug name setting interface 520, thereby also facilitating a reduction in the preparation time for an infusion operation.

In one embodiment, when the processor 150 receives the feedback signal transmitted by the first position sensor and/or the feedback signal transmitted by the second position sensor and the feedback signal transmitted by the pressure sensor disposed on the pushing block 1140, the processor 150 determines that a confirmation event is received that the syringe 60 or the infusion set 40 is disposed in the infusion pump 10 and controls the display screen 160 to display the drug name setting interface 520.

In one embodiment, the processor 150, upon receiving the feedback signal transmitted by the first position sensor and/or the feedback signal transmitted by the second position sensor, controls the display screen 160 to display the infusion parameter setting interface 510, and when the user operates the infusion parameter setting interface 510, such as the preset area 532 associated with the drug name in the infusion parameter setting interface 510 is triggered or selected, the processor 150 determines that a confirmation event is received that the injector 60 is disposed in the infusion pump 10, and controls the display screen 160 to display the drug name setting interface 520.

In one embodiment, when the processor 150 receives the feedback signal transmitted by the first position sensor and/or the feedback signal transmitted by the second position sensor and receives the feedback signal transmitted by the pressure sensor disposed on the pushing block 1140, the processor 150 controls the display screen 160 to display the infusion parameter setting interface 510, and when the user operates the infusion parameter setting interface 510, for example, the preset area 532 related to the drug name in the infusion parameter setting interface 510 is triggered or selected, the processor 150 determines that a confirmation event is received that the injector 60 is disposed in the infusion pump 10, and controls the display screen 160 to display the drug name setting interface 520.

In this embodiment, the drug name setting interface 520 includes one or more drug name options 530 and a function selection area 526, where each drug name option is located, including a corresponding drug name, and each drug name option is located in an area having corresponding color information. The color information of the area where the drug name selection item is located may be related to a category corresponding to the corresponding drug name. The class of drugs may correspond to the function of the drug, e.g., for a sedative class of drugs, the corresponding color information is a first color; for the analgesic class of drugs, the corresponding color information is a second color; for the muscle-relaxing drugs, the corresponding color information is a third color. In this embodiment, the drug names and corresponding color information corresponding to the drug name selections displayed in the drug name setting interface 520 may be stored in the memory 104 of the infusion pump 100, so that the processor 150 may retrieve from the memory 104 when displaying the drug name selections of the drug name setting interface 520, where the drug names and corresponding color information corresponding to the drug name selections may be stored in the memory 104 in the form of a data table. In an embodiment, the infusion pump 100 may be disposed in the connection dock 70 (shown in fig. 20), and the processor 150 of the infusion pump 100 may obtain the drug name and the corresponding color information corresponding to the drug name option stored in the network additional memory or server through the connection dock 70, or may obtain the drug name and the corresponding color information corresponding to the drug name option stored in the network additional memory or server accessed through the RF circuit 120 or the external port 122 and the communication network, wherein the communication network may be the internet, one or more internal networks, a Local Area Network (LAN), a wide area network (WLAN), a Storage Area Network (SAN), or the like.

In this embodiment, after retrieving the data table of drug names from the memory 104, the processor 150 may display the drug name selections based on the display mode of the drug name setting interface 520, including but not limited to a tiled display mode or an overlapping display mode.

Referring to fig. 12, a schematic diagram of a drug name selection item according to another embodiment of the application is shown. The processor 150 controls the medication name selections 530 to be displayed in a tiled display, wherein the areas where different medication name selections reside are independent of each other (as shown in fig. 11) or partially overlap (as shown in fig. 12) when displayed in a tiled display. The processor 150 may obtain the number of drug names stored in the data table and control the size of the area in which the drug name selection item 530 is located based on the obtained number of drug names, so that the user quickly selects a drug name for the fluid in the infusion set from among the tiled drug name selection items 530.

Referring to fig. 11, if the drug name selection item 530 displayed in the drug name setting interface 520 has a corresponding preset threshold value. When the number of the medicine name choices is greater than the preset threshold, the processor 150 controls the display screen 160 to display each medicine name choice in a display manner of the plurality of medicine name setting interfaces 520; when the number of drug name selections is not greater than the preset threshold, the processor 150 controls each drug name selection to be displayed within the same drug name setting interface 520. Within the medication name setting interface 520, the processor 150 also sets the size of the area in which the medication name selections 530 are located according to the number of medication name selections 530 included in the medication name setting interface 520, such that the size of the area in which each medication name selection 530 is located in the medication name setting interface 520 is maximized. For example, if the drug name options 530 have a corresponding preset threshold of 10, it means that one drug name setting interface 520 displays at most 10 drug name options 530. When 6 drug names are included in the data table for retrieving drug names, the processor 150 may control the drug name setting interface 520 to display the drug name selection item 530 in the form of 2 rows and 3 columns; when 10 drug names are included in the data table for retrieving drug names, the processor 150 may control the drug name setting interface 520 to display the drug name selection item 530 in the form of 2 rows and 5 columns; when 5 drug names are included in the data table for retrieving drug names, the processor 150 may control the drug name setting interface 520 to display the drug name selection item 530 in the form of 1 row and 5 columns; when 16 drug names are included in the data table of the retrieved drug names, the processor 150 may display two drug name setting interfaces 520, wherein the first drug name setting interface 520 displays the drug name selections 530 in 2 rows and 5 columns and the second drug name setting interface 520 displays the drug name selections 530 in 2 rows and 3 columns. When there are multiple drug name setting interfaces 520 displaying drug name selections in the data sheet, the processor 150 may display a multi-screen logo 552 (shown in fig. 16) on the drug name setting interface 520, and the user may switch among the multiple drug name setting interfaces 520 by a particular gesture operation on the display screen 160, including, but not limited to, sliding left, sliding right, sliding down, sliding up, clicking one or more fingers, etc.

On the premise that the size of the display screen 160 is fixed, when the number of the drug name options included in the drug name setting interface is different, the size of the area where each drug name option is located is different. In this way, when the number of the medicine name choices included in the medicine name setting interface reaches a certain value, the area where each medicine name choice of the medicine name setting interface 520 is located becomes smaller. If the drug name setting interface 520 displays the drug name selections in 1 row and 5 column or in 2 rows and 5 columns, the area where the drug name selections displayed in 2 rows and 5 columns are located will be smaller than the area displayed in 1 row and 5 columns. Therefore, the area where the drug name options are located is reduced, and when the user selects the drug name options, a plurality of drug name options may be selected at the same time, so that the possibility of incorrect selection exists. To facilitate the user to select from the plurality of drug name selections 530, the processor 150 controls the drug name selections 530 to be displayed in a partially overlapping tile to increase the area in which the drug name selections 530 are located, wherein when displayed in a partially overlapping tile, there is a partial overlap in the area in which different drug name selections are located, such as in displaying the drug name setup interface 520 that includes 10 drug name selections, the processor 150 may also display in 1 row and multiple rows without displaying in 2 rows and 5 columns. The processor 150 may control the region of the drug name selection item 530 located at one side to be displayed completely, and the regions of the other drug name selection items 530 located at the other side to be displayed overlapping each other (as shown in fig. 14); alternatively, the processor 150 may control the display of the areas where the drug name selections 530 are located on the non-two sides to be displayed entirely, and the areas where the other drug name selections 530 are located are displayed overlapping each other (as shown in fig. 12). For example, when 8 drug names are included in the data table of the retrieved drug names, if displayed in a tiled manner, the processor 150 controls the drug name setting interface 520 to display the drug name selection item 530 in the form of 2 rows and 4 columns. If displayed in an overlapping manner, the processor 150 may display each of the medication name selections 530 in the form of the size of the area in which the medication name selections 530 were displayed in 1 row and 5 column. The user may also select by gesture operations when selecting the corresponding medication name selection 530.

Referring to fig. 13, a change diagram of a display of a drug name selection item in a drug name setting interface according to an embodiment of the application is shown. Upon detection of a drug name setting event, the processor 150 obtains or retrieves the drug name data table, and then controls the drug name selections 530 contained in the drug name data table to be displayed in the drug name setting interface 520 in a tile of individual drug name selections, e.g., one drug name selection 530 is displayed, and the other drug name selections 530 may be hidden behind the displayed drug name selections 530. If the user needs to view each drug name in the drug name data table, the user may click or touch the area where the displayed drug name selection item 530 is located, at which time the processor 150 detects a switch display event of the drug name setting interface. Processor 150 responds to the switch display event and adjusts the tiling of individual medication name selections to independent tiling.

Referring to fig. 14, a change diagram of a display of a drug name selection item in a drug name setting interface according to another embodiment of the application is shown. In the medication name setting interface 520, the processor 150 may control the medication name selection 530 to be tiled with individual medication name selections. In contrast to the embodiment corresponding to fig. 13, in this embodiment, when the processor 150 detects the switching display event of the drug name setting interface, the processor 150 adjusts the tiling manner of the single drug name option to the partially overlapping tiling manner.

Referring to fig. 15, a schematic diagram of a drug name selection item according to another embodiment of the application is shown. Each of the drug names in the data table of drug names stored in the memory 104 also has a corresponding category attribute, that is, each drug name has corresponding category information, where each category is classified by the drug infusion function satisfying a preset condition, the category information includes, but is not limited to, a "usual" category, a "sedative" category, a "analgesic" category, a "myotonic" category, and a "other" category, so that the drug name satisfying the usual function may be classified as a "usual" category, the drug name satisfying the sedative function may be classified as a "sedative" category, the drug name satisfying the analgesic function may be classified as an "analgesic" category, the drug name satisfying the myotonic function may be classified as a "myotonic" category, and the drug name of other functions may be classified as a "other" category. After retrieving each drug name in the drug name data table, the processor 150 displays the drug name data table according to the category information included in the drug name data table. For example, the processor 150 may control the display screen 160 to display a plurality of medication name setting sub-interfaces 524, each medication name setting sub-interface 524 may correspond to a category in the data table of medication names. Each medication name setting sub-interface 524 contains at least one medication name setting selection 530. As shown in fig. 15, the display 160 includes 5 drug name setting sub-interfaces 524, where the "usual" drug name setting sub-interface 524 corresponds to the "usual" category, the "sedative" drug name setting sub-interface 524 corresponds to the "sedative" category, the "analgesic" drug name setting sub-interface 524 corresponds to the "analgesic" category, the "muscle loose" drug name setting sub-interface 524 corresponds to the "muscle loose" category, and the "other" drug name setting sub-interface 524 corresponds to the "other" category.

In this embodiment, the processor 150 displays each drug name setting sub-interface 524 in the form of a tab page on the display screen 169, where the tab name of each tab page is corresponding category information. As such, the user may select the corresponding medication name setting sub-interface 524 based on the tag name of the tag page. The processor 150 may display the corresponding medication name setting sub-interface 524 according to a switching event (e.g., a touch operation to select the corresponding tab page) to switch the medication name setting interface. For example, if the interface currently displayed on the display screen 160 is the "usual" medication name setting sub-interface 524, if the processor 150 receives a user click on the "analgesic" tab page, the processor 150 determines that a switching event is received, at which point the processor 150 responds to the switching event and controls the display screen 160 to display the "analgesic" medication name setting sub-interface 524. In one embodiment, the processor 150 defaults to displaying the "commonly used" medication name settings sub-interface 524 upon detection of a medication name setting event, such that a user may quickly select a "commonly used" category of medication name from the "commonly used" medication name settings sub-interface 524. In an embodiment, the processor 150 may display the drug name setting sub-interface 524 under the corresponding category based on an input operation by the user. For example, if the "analgesic" medication name setting sub-interface 524 is currently displayed, if an input operation of sliding left or other gestures input by the user is received, the user is indicated to need to view the next medication name setting sub-interface, at this time, the processor 150 controls the display screen 160 to display the "muscular-relaxation" medication name setting sub-interface 524; if the user again enters a left swipe input operation or other gesture, processor 150 may control display screen 160 to display "other" medication name settings sub-interface 524. If an input operation or other gesture to slide to the right is received while the "other" medication name setting sub-interface 524 is displayed, indicating that the user needs to view the last medication name setting sub-interface of the current medication name setting sub-interface, at this point, the processor 150 controls the display screen 160 to display the "muscle loose" medication name setting sub-interface 524.

The drug name selection item 530 in each drug name setting sub-interface 524 is used to present drug names whose frequency of use satisfies a first preset condition. For example, the processor 150 may display the selected drug name selection item 530 having a frequency of use greater than a first preset frequency within the drug name setting sub-interface 524, and the selected drug name selection item 530 may be displayed in a frequency of use manner or in a random manner. The processor 150 may control the display of the selected medication name selection 530 in the medication name setting sub-interface 524 based on different display manners. The display modes include, but are not limited to, the various tiling modes described above.

In one embodiment, since infusion pump 100 may be used by a particular department (ICU, OR operating room, etc.) OR user (ICU nurse, OR nurse), there is a variance in the frequency of medications used by each department OR user. Thus, the processor 150 may present the medication name selection 530 contained in the medication name setting sub-interface 524 according to the current user or current department. For example, the processor 150 may select a target medicine name whose frequency of use of the current user or the current department satisfies the second preset condition from the medicine name selection items 530 included in the medicine name setting sub-interface 524, and display the medicine name selection item 530 corresponding to the target medicine name in the medicine name setting sub-interface 524. Thus, the user can quickly select the drug name with high frequency from the drug name setting sub-interface 524 or the department to which the user belongs, which is beneficial to reducing the time for selecting the drug name.

Referring to fig. 15 and 16, fig. 16 is a schematic diagram illustrating a medicine name query operation according to an embodiment of the application. Also included within the display screen 160 is a query trigger area 522, which when triggered, the processor 150 may control the display screen 160 to display a separate query interface (or query area) 550. The query interface 550 includes a display area for query identification and a function selection area 526. The query identifier comprises one or more letters and upon receipt of a user click on the corresponding query identifier, the processor 150 controls the display of one or more medication name selections 530 corresponding to the clicked query identifier within the query interface 550. When the number of medication name selections 530 corresponding to the clicked query identifier exceeds a certain number, the processor 150 also controls the query interface 550 to display the multi-screen identifier 552 so that the user can switch by gesture operations. In this embodiment, since the query interface 550 is displayed as a separate interface, the user may click on the "back" button in the function selection area 526 when the user wants to return to the medication name setting interface 520. If the user selects the determined medication name option 530 at the query interface 550, the processor 150 may control the display 160 to display the infusion parameter setting interface 510 corresponding to the determined medication name option 530. In an embodiment, the query identifiers may correspond to the drug names with corresponding category information, so that each query identifier may also have color information consistent with the corresponding category information, such as the query identifier corresponding to the general "category having a first color, the query identifier corresponding to the" sedative "category having a second color, the query identifier corresponding to the" analgesic "category having a third color, the query identifier corresponding to the" myotonic "category having a fourth color, and the query identifiers corresponding to the" other "categories having a fifth color, so that when the user clicks the query identifier of the corresponding color, the drug name selection corresponding to the corresponding selected color may be queried.

Referring to fig. 17, a schematic diagram of a drug name query operation according to another embodiment of the application is shown. When the query triggering area is triggered, the processor 150 may control the medicine name setting interface 520 of the display 160 to display the query area 554, wherein the query area 554 may also display a virtual keyboard, and the virtual keyboard may include a plurality of keys, and the first key corresponds to a query identifier. When the drug name setting interface 520 does not have a query trigger area, the user may also input a specific gesture operation on the drug name setting interface 520 to call out the query area 554 or the query interface 550. As shown in FIG. 9, a user may enter a three-way swipe down gesture within display screen 160, which, when received by processor 150, may bring up a query area 554 as shown in FIG. 15 or a query interface 550 as shown in FIG. 14.

After the user clicks a key in the query area 554, the processor 150 controls the medication name area in the medication name setting interface 520 to display a corresponding medication name selection 530 according to the query identifier corresponding to the clicked key. In this embodiment, the query area 554 is displayed on the left side of the drug name setting interface 520, and in other embodiments, the query area 554 may be displayed on the right side of the drug name setting interface 520 or at other positions on the display screen 160.

Step 104, detecting a trigger event based on the drug name selection item, and determining the target drug name corresponding to the selected drug name selection item.

The user may gesture or otherwise manipulate (including but not limited to, clicking, double clicking, sliding, etc.) the corresponding medication name selection 530 within the medication name setting interface 520 or the medication name setting sub-interface 524, at which point the processor 150 detects a trigger event based on the medication name selection and determines the target medication name to which the selected medication name selection corresponds. As shown in fig. 11, when the user clicks on the drug name selection item of "sufentanil" in the drug name setting interface 520, the processor 150 may take "sufentanil" as the target drug name.

And 106, determining the corresponding transfusion parameter content according to the target medicine name.

Referring to fig. 18, a schematic diagram of a parameter option interface corresponding to a target drug name according to an embodiment of the application is shown. Upon detection of a trigger event based on the medication name selection, it is indicative that the user has determined the medication of the fluid within the infusion set. The user also needs to set or determine the content of the infusion parameters associated with the infusion operation. In this embodiment, the processor 150 displays a corresponding parameter option interface 570 according to the name of the target drug, wherein the parameter option interface 570 includes the flow rate, infusion mode, preset amount, predicted time, and the like associated with the start of the infusion operation. Since the infusion parameter content corresponding to each drug name may be different, in order to facilitate the user to save the time of the preparation process of the infusion operation, the memory 104 may be preset to store the infusion parameter content corresponding to each drug name. In one embodiment, the preset infusion parameter content may be set based on the infusion parameter content used by the corresponding medication name in the historical infusion operation. As such, the processor 150 may retrieve from the memory 104 the infusion parameter content preset in the memory 104 corresponding to the target medication objective and display in the parameter options interface 570.

In one embodiment, if the user has set the related infusion parameter content in the infusion parameter setting interface 510, the processor 150 may read and display the set infusion parameter content in the infusion parameter setting interface 510 at the corresponding position of the parameter option interface 570, so that the user does not need to set the infusion parameter content again in the parameter option interface 570. For example, the user may have set the infusion parameter content of the flow rate (e.g., set to A) in the infusion parameter setting interface 510, and the processor 150 may set the infusion parameter content of the flow rate in the parameter options interface 570 to A. In one embodiment, the user may also perform operations such as changing the infusion parameter content of the flow rate at the parameter options interface 570.

And step 108, driving the driving mechanism to move according to the transfusion parameter content so as to enable the liquid in the syringe to move according to the transfusion direction.

In this embodiment, the user determines that the associated infusion parameters within the parameter options interface 570 are correct, and the user may activate the "start" button in the function selection area 526. The processor 150 may receive an initiate infusion instruction. In other embodiments, the processor 150 may receive an initiate infusion instruction sent by the Dock processor (docking station). For example, a plurality of infusion pumps and/or infusion pumps may be connected in Dock, which may be used to sequentially perform infusion/injection operations with respective set medications in a preset order. Dock may send an initiate infusion command to a corresponding syringe pump according to the order of infusion operations of the plurality of syringe pumps. For patient safety, the infusion operation of the infusion pump/syringe pump arranged in the first position needs to be confirmed by the medical staff and an activation operation performed on the pump; when the infusion operation of the infusion pump/syringe pump at the first position is detected to be completed or is about to be completed, the Dock processor can send an infusion starting instruction to the infusion pump/syringe pump at the second position, which is positioned behind the first position in sequence, so that the infusion pump/syringe pump at the second position can execute the infusion starting operation after receiving the infusion starting instruction sent by the Dock.

Referring to fig. 7 again, in the present embodiment, the pump door 112 of the syringe pump 10 may be provided with a plurality of display screens 160, for example, a first display screen for displaying the infusion parameter setting interface 510, the drug name setting interface 520, the drug name setting sub-interface 524 or the parameter option interface 570, and a second display screen for displaying the function operation interface 512. As shown in fig. 7, the function operation interface 512 includes a progress bar display area 518, a menu key area 514, and a switch key area 516. When the driving mechanism 133 drives the push-pull mechanism 114 to perform an infusion operation, indicating that the syringe pump 10 is performing an infusion operation, the processor 150 may control the progress bar display area 518 to have first color information (e.g., green); upon completion of the infusion operation, processor 150 may control progress bar display area 518 to have second color information (e.g., red); when the syringe pump 10 is not performing an infusion operation and the syringe 60 is not disposed in the syringe pump 10, the processor 150 may control the progress bar display area 518 to have third color information (e.g., gray).

Referring to fig. 19, a schematic diagram of an infusion pump according to another embodiment of the present application is shown. In this embodiment, the pump door 207 of the infusion pump 20 may be provided with a plurality of display screens 205, for example, a first display screen for displaying the infusion parameter setting interface 510, the drug name setting interface 520, the drug name setting sub-interface 524, or the parameter option interface 570, and a second display screen for displaying the function operation interface 513. As shown in fig. 19, the function operation interface 513 may also include a progress bar display area 519, a menu key area 515, and a switch key area 517. When the peristaltic compression mechanism 200 is performing an infusion operation, indicating that the infusion pump 20 is performing an infusion operation, the processor 150 may control the progress bar display 519 to have a first color information (e.g., green); upon completion of the infusion operation, the processor 150 may control the progress bar display 519 to have second color information (e.g., red); when the infusion pump 20 is not performing an infusion operation and the syringe 60 is not provided in the infusion pump 20, the processor 150 may control the progress bar display area 519 to have third color information (e.g., gray).

In one embodiment, the infusion pump 100 may display a tubing guide interface on a display screen at power-on or during or prior to changing the infusion set, including but not limited to, the orientation of the infusion set, considerations during set-up, etc., to facilitate accurate set-up of the infusion set by the user. In other embodiments, the processor 150 may control the first display screen to display the tubing guide interface upon or before detecting that the infusion set is in a set state disposed in the infusion pump 100 as normal.

In one embodiment, the pump door 112 is provided with a display 160, so that the infusion parameter setting interface 510 and the function operation interface 512 can be disposed in different areas of the display 160.

Because the existing infusion pump has a smaller screen, the drug name can be selected only after a plurality of steps such as up-and-down selection OR sub-menu entering are performed through keys, and when the operation steps are more in the case of needing emergency treatment (such as ICU, OR operating room and other departments), the longer waiting time is caused, so that the time before infusion is started is longer, and even the treatment of the patient is possibly influenced. According to the infusion pump control method, the drug name setting interface is displayed after the drug name setting event is detected, the drug name setting interface comprises the drug name options obtained from the infusion pump or from a plurality of channels such as a network, and the drug name options are displayed in a tiled display mode, so that a user can conveniently and quickly select the drug name in the displayed drug name setting interface. The defect that the prior user can possibly carry out the medicament name after a plurality of operation steps is overcome, and the preparation time of the infusion operation is reduced. In addition, aiming at the condition of the injection pump, when the injection pump detects that the pump door is closed and the injector is arranged in the injection pump, the control display screen displays the infusion parameter setting interface or the medicine name setting interface, so that the defect of waste of infusion time caused by displaying the infusion parameter setting interface after the push-pull mechanism is propped against the piston handle after waiting for the preset time of operation can be reduced. The infusion pump control method detects and can control the action of the push-pull mechanism while inputting and/or confirming infusion parameters through the infusion parameter equipment interface, so that the time for preparing the infusion is also reduced.

Referring to fig. 20, a schematic diagram of an infusion pump system in accordance with an embodiment of the present application is shown. In this embodiment, the infusion pump system 90 includes a docking station (Dock) 70 and a plurality of infusion pumps 20/syringe pumps 10 each connected to the docking station 70. Each infusion pump 20/syringe pump 10 is adapted for use with an infusion set (infusion tube/syringe), and the functions and components associated with the infusion pump 100 are as described in the previous embodiments. The docking station 70 includes a docking station processor, a network interface, a peripheral interface, and the like, wherein the docking station 70 is connected to the server through the network interface, and the docking station processor receives the order information including the plurality of medication name options transmitted from the server through the network interface. The docking station processor may parse the received order information to obtain a plurality of medication name selections. The docking station processor also transmits the obtained plurality of medication name selections to each infusion pump 100.

Each infusion pump 100 displays a drug name setting interface on a corresponding display screen when receiving a plurality of drug name options transmitted by the docking station processor, wherein the drug name setting interface comprises the plurality of drug name options, the areas where different drug name options are located are independent or partially overlapped, and the drug name options are used for presenting drug names included in the doctor's advice information.

For example, the order information received by the docking station 70 contains 6 drug name choices, "sufentanil," epinephrine, "" octreotide, "" sodium nitroprusside, "" sitagland "dopamine," respectively. If the first, second and third infusion pumps are connected to the connection dock 70, when the first, second and third infusion pumps receive the drug names transmitted by the connection dock 70, the first, second and third infusion pumps each display a drug name setting interface including the 6 drug name options on their own display screens, such as the drug name setting interface 520 shown in fig. 9. In other embodiments, the number of medication name selections included in the order information transmitted by the server to the docking station 70 may be the same number of infusion pumps 100 connected to the docking station 70.

The user may enter a trigger event for a medication name selection in a medication name setting interface of one of the 3 infusion pumps (e.g., the first infusion pump), and the processor of the first infusion pump may determine a target medication name corresponding to the selected medication name selection and determine corresponding infusion parameter content based on the target medication name. For example, when the user selects the "sufentanil" drug name option of the drug name setting interface of the first infusion pump, the first infusion pump may display a parameter selection interface within its display screen as shown in fig. 16. And then, when a user clicks a start button in the parameter selection interface, the processor of the first infusion pump receives a user instruction, and drives a driving mechanism of the first infusion pump (or triggers the infusion pump) to move according to the corresponding infusion parameter content so as to enable liquid in the injector of the first infusion pump to move towards the infusion direction.

In this embodiment, after the user clicks the "start" button in the trigger infusion pump, the trigger infusion pump sends the user selected target drug name information to the processor of the docking station 70. Since the medication name options in the order information are selected, it means that other infusion pumps may not need to use the selected medication name options any more. The docking station 70 may adjust the medication name setting interface in other infusion pumps to remove the medication name selection corresponding to the selected target medication name from the medication name setting interface in other such infusion pumps. For example, the connection 70 may control the second and third infusion pumps to remove "sufentanil" drug name choices from their respective drug name setting interfaces, where the drug name setting interfaces of the second and third infusion pumps only include the remaining 5 drug name choices.

In this embodiment, during the infusion operation of the first infusion pump, the user may select the corresponding drug name option in the drug name setting interface of the second infusion pump and the third infusion pump. For example, the user may select the "adrenergic" medication name option at the second infusion pump, at which point the docking station 70 may control the third infusion pump to remove the "adrenergic" medication name option from its own medication name setting interface.

When the first infusion pump infusion is complete, the first infusion pump may transmit an infusion complete signal to the docking station 70. The docking station 70 may transmit an infusion initiation command to a second infusion pump that initiates an infusion operation upon receiving the infusion initiation command. Similarly, when the second infusion pump infusion is complete, the second infusion pump may transmit an infusion complete signal to the docking station 70. The docking station 70 may transmit an infusion initiation command to a third infusion pump that initiates an infusion operation upon receiving the infusion initiation command.

In an embodiment, the patient may need to infuse the same medication through multiple infusion pumps, and as such, there are two or more identical medication names contained in the order information. When the same medication name is selected by the user in the display of one infusion pump, the docking station 70 controls the medication name setting interface of the other infusion pump to decrease or remove one or more of the number of medication names corresponding to the same medication name, and the user may select another one or more of the same medication names in the display of the other infusion pump.

According to the infusion pump system, the drug name setting interface is displayed after the drug name setting event is detected, so that a user can conveniently and quickly select the drug name in the displayed drug name setting interface, and the time for preparing an infusion operation is reduced. In addition, the infusion pump system can control the starting infusion operation of a plurality of infusion pumps through the connecting dock, and can set other infusion pumps during the infusion of one infusion pump, and can also reduce the preparation time of the infusion operation.
