It is explicitly and implicitly understood by one skilled in the art that the embodiments described herein can be combined with other embodiments.

The following describes embodiments of the present application in detail.

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

at step 100, a drug name setting event is detected.

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

Referring to fig. 2, a schematic structural diagram of an injection pump according to an embodiment of the present application is shown. The syringe pump 10 includes a pump body 110, a pump door 112 rotatably provided on the pump body 110, a grip mechanism 118 provided on the pump body 110, a receiving groove 116 provided on one side end of the pump body 110, and a push-pull mechanism 114 provided on the side end of the receiving groove 116 and movable in a predetermined direction (infusion direction or reverse infusion direction) by a drive mechanism 133 (shown in fig. 9).

Please refer to fig. 3, which is a schematic structural diagram of an infusion pump according to an embodiment of the present application. The infusion pump 20 includes a pump body 201, a display system 205, a peristaltic squeezing mechanism 200 (shown in fig. 9) and a pump door 207, and the pump door 207 is movably installed on the pump body 201 to cover a receiving cavity 216 for receiving the infusion tube 40, and sometimes the receiving cavity 216 for receiving the infusion tube 40 is 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 to face 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 center line of the front surface of the pump door 207 to the right side of the center line of the front surface of the pump door, and the width of the display system 205 is greater than the height thereof, and the display system is disposed on the pump door in an elongated shape as a whole.

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 pump door 207 exhibits a lateral dimension that is greater than a longitudinal dimension, i.e., a width that is greater than a height, display system 205 has a width that is greater than its height, thereby allowing a larger area of display area to be obtained and allowing display system 205 to exhibit a rectangular shape with a lateral length. Wherein the pump door 207 is further provided with a physical input key 203 disposed on one side of the display system, for example, the physical input key 203 may be partially or entirely on the right side, upper side, lower side or left side of the display system. The user may enter data or instructions through 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 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 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 the display screens is formed by laminating a touch layer and a display layer, and the rest of the 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 screen included in the display system 205 is formed by laminating a touch layer and a display layer.

Referring to fig. 4, a schematic diagram of the peristaltic squeezing mechanism and the arrangement of the infusion tube according to an embodiment of the present application is shown. The peristaltic compression mechanism 200 includes a camshaft 202, a set of pump plates 204, and a compression plate 206. A processor in the infusion pump 20 sends a command such as a rotating speed or a position, and drives a power device 208 (such as a motor) to operate according to a specified rotating speed and a specified steering direction through a power driving circuit 130 (shown in fig. 5), and the power device (or a driving mechanism) 208 drives a camshaft 202 connected with the power device (or the driving mechanism) to rotate in the rotating process; during the rotation of the camshaft 202, the pump blade set 204 on the camshaft 202 performs a linear reciprocating motion, that is, the pump blades on the pump blade set 204 sequentially perform a linear reciprocating motion. The pump plate set 204 and the pressing plate 206 cooperate to sequentially and reciprocally press and release the outer wall of the infusion tube 40, so as to drive the liquid in the infusion tube 40 to continuously and directionally flow. A speed reducing mechanism may be further disposed between the power device 205 and the camshaft 204 to ensure that the rotation speed of the pump blade set 204 is stable and uniform.

In this embodiment, the infusion pump 100 may operate in a priming phase or a priming phase of an infusion operation. For the infusion pump, the preparation for infusion operation includes disposing the syringe 60 in the infusion pump 10, upon detecting a confirmation event that the syringe 60 is disposed in the infusion pump 10, the infusion pump 10 controls the push-pull mechanism 114 to move toward the piston handle 606 of the syringe 60, and if the push-pull mechanism 114 contacts with the piston handle 606 (shown in fig. 8) of the syringe 60 and receives an infusion operation start command, the infusion pump 10 enters an infusion operation start phase; during the initial infusion phase of operation, the syringe pump 10 controls the movement of the fluid in the syringe 60 in the infusion direction based on the set infusion parameter (e.g., flow rate) setting. In the case of a syringe pump, preparation for an infusion operation includes placing the infusion tube 40 in the receiving cavity 216 of the infusion pump 20, and upon detecting that the infusion tube 40 is placed in the infusion pump 20 in place, the user can perform an input operation in the display system 205, such as sending an infusion operation start command and setting infusion parameters. After the infusion operation start instruction, the injection pump 10 enters the infusion operation start phase; during the initial infusion phase, the infusion pump 20 controls the movement of the peristaltic squeezing mechanism 200 according to the set infusion parameters (e.g., flow rate) to move the fluid in the infusion tube 40 in the infusion direction.

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 stop clamp to open, so that the liquid stop clamp releases the infusion tube 40. Specifically, a front-end detection device is disposed within the infusion pump 20, wherein the front-end detection device may include one or two or more position sensors 164. For example, when a position sensor is disposed at a location of the receiving cavity 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 provided at a first target location of the receiving chamber 216 and a position sensor is provided at a second target location, such that both position sensors detect and transmit feedback information, then the infusion tube 40 is determined to be disposed within the infusion pump 20; the control platform 102 may actuate the clamp stop to open when the at least one position sensor 164 detects that the wall of the infusion tube 40 is not in contact with the receiving cavity 216. The receiving chamber 216 is defined within the infusion pump where the infusion set is mounted.

The displacement sensor 166 may be responsive to a change in position of the object being measured relative to the reference position and convert the change in position to a detectable electrical signal and transmit the electrical signal 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 alerting the infusion pump 100 of an abnormal condition. The light assemblies 168 are individually responsive to actuation of the processor/controller 150; the light assembly 168 may also be correspondingly engaged with the speaker 154 in response to activation of the processor/controller 150, such as a light that changes color or intensity with the tone, frequency, or duration of the warning sound. The light assembly 168 may include an indicator light or a fluid delivery fault condition warning light for components such as a power source, CPU, etc. The light assembly 168 may also include visual illumination elements for facilitating viewing of the structure or assembly status of the infusion pump 100 in the event of poor ambient light.

In one embodiment, the touch module 174 may selectively detect contact with the display screen 160 or other touch sensitive device (e.g., touch buttons, touch pad). For example, the touch module 174 and the display controller 140 together detect contact with the display screen 160. 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 finger press time), determining the strength of contact (e.g., force or pressure of 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 ceased (e.g., detecting finger lift time or contact break). The operation in which the movement of the point of contact is determined may include determining a velocity (magnitude), a velocity (magnitude and direction), and/or an acceleration (including magnitude and/or direction) of the point of contact. These operations may be applied to single point contacts or multiple simultaneous 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 input by a user. Different gestures by the user on the touch-sensitive device have different contact patterns (e.g., one or more combinations of locations, times, or intensities at which contacts are detected). For example, detecting a single-finger tap 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 the surface of the touch device includes detecting a finger-down event, then monitoring for one or more finger-dragging events, and then detecting a finger-up 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 outputs 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, after detecting contact with the surface of the touch device, the color of the graphics or text of the touch device changes, or sound or vibration is generated.

Fig. 6 is a schematic view of a syringe installed in a syringe pump according to an embodiment of the present application. 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 axially slidably connected to the pump body 110, and the push-pull mechanism 114 is driven by the driving mechanism 133 to move axially along the connecting rod 1142. The clamp mechanism 118 is rotatably disposed on the pump body 112, and the clamp mechanism 118 is switchable between a first state and a second state by a rotational operation of a user. The clip handle mechanism 118 is located within a receiving cavity of the syringe pump 10, wherein the receiving cavity is for receiving the syringe 60. Before setting the syringe 60, the user may rotate the grip mechanism 118 from the first state to the second state and pull the push-pull mechanism 114 out a preset length in a direction away from the pump body 110 so that the syringe pump 10 has sufficient space to set the syringe 60.

In this embodiment, the injector 60 includes an injector body 602, a flange 604 disposed at one end of the injector body 602, and a piston stem 606, wherein the injector body 602 is hollow for receiving the piston stem 606, and the piston stem 606 can move in a radial direction of the injector body 602. When the syringe 60 is disposed in the syringe pump 10, the user can rotate the clamping mechanism 118 to the second state to press the syringe body 602 onto the pump main body 110 of the syringe pump, the flange 604 of the syringe 50 is received in the receiving groove 116 of the pump main body 110, and the distance between the piston rod 606 and the push block 1140 is the predetermined distance d (shown in fig. 7).

In this embodiment, a position sensor 164 may be disposed in the pump door 112, and the processor 150 determines the state of the pump door 112 through the position sensor disposed in the pump door 112, wherein the state of the pump door 112 includes an open state and a closed state. As shown in fig. 6, the processor 150 may determine that the pump door 112 is in the open state by providing a position sensor. Please refer to fig. 7, which is a schematic diagram illustrating a state where a pump door of the syringe pump is closed according to an embodiment of the present application. As shown in fig. 7, processor 150 may determine that pump door 112 is in the closed state via a position sensor.

In this embodiment, processor 150 obtains a confirmation event that syringe 60 is disposed within 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 disposed 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 may be disposed within the clamp mechanism 118, and the clamp mechanism 118 may be in a second state when the syringe 60 disposed within the syringe pump 10 is press-fitted onto the pump body 110 of the syringe pump 10, wherein the first position sensor may transmit a feedback signal. For example, when the syringe 60 is disposed within the syringe pump 10, the clamp handle 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, processor 150 may obtain the feedback signal transmitted by the first position sensor to determine that syringe body 602 of syringe 60 is pressed against pump body 110 of syringe pump 10. In other embodiments, a pressure sensor may be disposed within the clamp mechanism 118 or at a corresponding location on the pump body 110, i.e., the pressure sensor may contact the syringe 60 when the syringe 60 is press-fitted onto the pump body 110 of the syringe pump 10, thereby generating a feedback signal with pressure information. Processor 150 may also determine whether to press syringe 60 disposed within syringe pump 10 against pump body 110 of syringe pump 10 based on the received feedback signal with pressure information.

The second position sensor is disposed in the receiving groove 116. When the syringe 60 is disposed in the syringe pump 10, the flange 604 of the syringe 60 is received in the receiving groove 116, and the second position sensor may output a feedback signal. In this way, when the processor 150 receives the feedback signal output by the second position sensor, the processor 150 can confirm that the flange 604 of the injector 60 is received in the receiving slot 116.

Processor 150 may detect the status of pump door 112 based on a sensor disposed within pump door 112 and may also detect the status of syringe 60 based on a first position sensor and/or a second position sensor. In one embodiment, 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 receipt of a confirmation event that syringe 60 is disposed within infusion pump 10.

In one embodiment, processor 150 may determine that syringe 60 is disposed in syringe pump 10 when both the first position sensor and the second position sensor transmit feedback signals to processor 150; when processor 150 does not receive a feedback signal transmitted by either of the first position sensor and the second position sensor, processor 150 may determine that the setting status of injector 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 accommodated in the accommodating groove 116, and thus detects that the installation state of the syringe 60 is abnormal; when the processor 150 receives the feedback signal transmitted by the second position sensor but does not receive the feedback signal transmitted by the first position sensor, it indicates that the user does not turn the clamping mechanism 118 to the second state, the clamping mechanism 118 does not fix the syringe body 602 to the pump main body 110, and the processor 150 can also detect that the setting state of the syringe 60 is abnormal. When determining that the setting state of the injector 60 is abnormal, the processor 150 controls the display screen or display system 160 to output a message indicating that the setting state of the injector 60 is abnormal, and the processor 150 may further control the light assembly 168 to output a message indicating that the setting state of the injector 60 is abnormal through the light controller 148.

In one embodiment, if pump door 112 is in a closed state and syringe 60 is not disposed within syringe pump 10, syringe pump 10 may be in a shut-down state or a standby state, and if a user uses syringe pump 10 to perform an infusion task with syringe 60, the user may need to open pump door 112 of 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 setup of injector 60 by a user (i.e., during the time period from when processor 150 detects that pump door 112 is open to when processor 150 detects that pump door 112 is closed), syringe pump 10 may perform a self-test operation to detect the device status of syringe pump 10. Self-test operation of syringe pump 10 includes, but is not limited to, voice self-test, processor self-test, external storage device self-test, alarm light self-test, power self-test, and sensor self-test; the infusion pump 20 may also perform a pressure self-check operation. In performing the sound self-test, the processor 150 may control the speaker 154 to emit a sound through the audio circuit 124, and may determine whether the sound self-test passes through the recording device; if the processor receives a sound from speaker 154 via the recording device, it may determine that the sound self-test has passed, otherwise, it indicates an abnormal device status for syringe pump 10. During the self-check of the processor, the processor 150 may run a preset program in the memory 104 and determine whether a result obtained after the running of the preset program is a preset result; if the result obtained after the preset program is the preset result, it may be determined that the processor self-check has passed, otherwise, it indicates that the device state of the syringe pump 10 is abnormal. In addition, the processor 150 can also detect the external storage device, the light assembly 168, the power system 106, and the plurality of sensors. When each self-check operation passes, it is determined that the apparatus state of the syringe pump 10 is normal; when there is at least one failure of the self-test, then an abnormal device status of the syringe pump 10 is determined and a prompt for the abnormal device status may be output via the display screen 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 squeezing mechanism 200 to move in the 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 liquid stopper clamp is disposed in the accommodating cavity 216 and is close to the user end, if the peristaltic squeezing 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 increase, and further, if the pressure value detected by the pressure sensor increases, it is determined that the infusion tube 40 is normal; if the pressure sensor detects that the pressure value is reduced or unchanged, the infusion tube 40 is determined to be abnormal, and if the infusion tube is broken, the infusion pump 20 can output a prompt message of the abnormal pressure of the infusion tube through the display 205.

Please refer to fig. 8, which is a schematic view illustrating a state of the push-pull mechanism abutting against the piston shaft according to an embodiment of the present application. When the pump door 112 is closed and the syringe 60 is disposed in the syringe pump 10, the push block 1140 of the push-pull mechanism 114 is spaced a predetermined distance d from the piston stem 606, so that the drive mechanism 133 needs to push the push block 1140 toward the piston stem 606 after the predetermined distance d before the drive mechanism 133 controls the push-pull mechanism 114 to start the infusion operation, so that the push block 1140 is abutted against (or in contact with) the piston stem 606.

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

In one embodiment, a rear-end detection device, such as a pressure sensor, may be disposed on the pushing block 1140, such 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 the processor 150 may determine that the pushing block 1140 is abutted against the piston stem 606 when determining that the feedback signal transmitted by the pressure sensor disposed on the pushing block 1140 is received. 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 first position sensor, and receives the feedback signal transmitted by the rear end detection device disposed on the pushing block 1140, the processor 150 may 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 a syringe pump in accordance with an embodiment of the present invention is shown for initiating an infusion operation. In this embodiment, the push-pull mechanism 114 is configured to hold the plunger shaft 606 of the syringe 60. The processor 150 in the syringe pump 10 sends out instructions such as rotation speed or position, and drives a power device (for example, the driving mechanism 133) through the power driving circuit 130, the driving mechanism 133 drives the screw rod 135 and the nut 137 through the speed reducing mechanism, so as to convert the rotational motion of the driving mechanism 133 into the linear motion of the nut 137, the 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 660 of the matched syringe 60 to perform injection and infusion, and the pushing speed of the matched syringe 60 can be adjusted through the rotation speed (for example, the rotation speed of the second motor) of the driving mechanism 133, so as to adjust the given infusion dose and the infusion speed.

Please refer to fig. 10, which is a schematic view of an infusion parameter setting interface according to an embodiment of the present application. 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 the feedback signals transmitted by the first position sensor and the second position sensor, the processor 150 may 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 infusion parameter setting items for presenting one or more infusion parameter contents, including but not limited to infusion parameter contents such as infusion speed, flow rate unit, preset amount, preset time, infusion mode, consumable, drug name, and the like. Wherein the transfusion parameter setting item can be edited based on the selection of the user to adjust the transfusion parameter content displayed by the user. In one embodiment, when the processor of the infusion pump 20 detects that the pump door 207 is closed and the setting state 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 205 disposed on the pump door 207 to display an infusion parameter setting interface 510, wherein the infusion parameter setting interface 510 includes infusion parameter setting items for presenting one or more infusion parameter contents.

In this embodiment, the user can set the contents of the infusion parameters on 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 operate at the first motor rotation speed to drive the pushing mechanism 114 to move in the direction toward the piston shaft 606 of the injector 60, and the driving mechanism 133 pushes the pushing mechanism 114 against the piston shaft 606 after operating at the first motor rotation speed for a preset time. In this manner, the user controls the actuation of the push-pull mechanism 114 while performing the infusion parameter device via the infusion parameter device interface 510, which also facilitates 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 (e.g., the area where the "drug name" is located in fig. 10) related to the drug name, and when the preset area 532 is triggered by a user (including but not limited to a triggering gesture or operation, which may be a single click, a double click, a sliding motion, etc.), a selection event is generated to indicate 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 medication name setting event is detected.

And 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 selection items, areas where different drug name selection items are located are mutually independent or partially overlapped, and the drug name selection items are used for presenting drug names infused by the infusion pump.

Please refer to fig. 11, which is a diagram illustrating a display of a drug name selection item according to an embodiment of the present application. Upon detecting a 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 has been received that the syringe 60 or 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 injector 60, after receiving the feedback signal transmitted by the first position sensor and/or the second position sensor, the processor 150 may control the driving mechanism 133 to operate at the first motor speed to drive the pushing mechanism 114 to move in the direction toward the piston shaft 606 of the injector 60, and the driving mechanism 133 may control the pushing mechanism 114 to push against the piston shaft 606 after operating at the first motor speed for a predetermined time, because the pushing block 1140 of the pushing and pulling mechanism 114 has a predetermined distance d from the piston shaft 606, while the user operates in the displayed medicine name setting interface 520. The user controls the action of the push-pull mechanism 114 while selecting the drug name through the drug name setting interface 520, which is also advantageous in reducing the preparation time for the 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 receives the feedback signal transmitted by the pressure sensor disposed on the pushing block 1140, the processor 150 determines that a confirmation event that the injector 60 or the infusion set 40 is disposed in the infusion pump 10 is received, and controls the display screen 160 to display the drug name setting interface 520.

In one embodiment, the processor 150 controls the display 160 to display the infusion parameter setting interface 510 when receiving the feedback signal transmitted by the first position sensor and/or the feedback signal transmitted by the second position sensor, and the processor 150 determines that a confirmation event that the syringe 60 is set in the infusion pump 10 is received 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, and controls the display 160 to display the drug name setting interface 520.

In one embodiment, the processor 150 controls the display 160 to display the infusion parameter setting interface 510 when 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, and the processor 150 determines that a confirmation event that the syringe 60 is disposed in the infusion pump 10 is received and controls the display 160 to display the drug name setting interface 520 when the infusion parameter setting interface 510 is operated by the user, for example, the preset area 532 related to the drug name in the infusion parameter setting interface 510 is triggered or selected.

In this embodiment, the drug name setting interface 520 includes one or more drug name selection items 530 and a function selection area 526, where an area where each drug name selection item is located includes a corresponding drug name, and the area where each drug name selection item is located has corresponding color information. The color information of the region where the drug name selection item is located may be related to the category corresponding to the corresponding drug name. The category of the drug may correspond to a function of the drug, e.g., for a sedation category 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 drugs in the muscle relaxation category, the corresponding color information is a third color. In this embodiment, the drug name and the corresponding color information corresponding to the drug name selection item 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 the drug name and the corresponding color information from the memory 104 when the drug name selection item of the drug name setting interface 520 is displayed, wherein the drug name and the corresponding color information corresponding to the drug name selection item may be stored in the memory 104 in a form of a data table. In one embodiment, the infusion pump 100 may be disposed at the docking station 70 (shown in fig. 20), and the processor 150 of the infusion pump 100 may obtain the drug name and corresponding color information corresponding to the drug name selection item stored in the network attached memory or the server through the docking station 70, or the drug name and corresponding color information corresponding to the drug name selection item stored in the network attached memory or the server accessed through the RF circuit 120 or the external port 122 and a communication network, such as the internet, one or more internal networks, a Local Area Network (LAN), a wide area network (WLAN), a Storage Area Network (SAN), etc.

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

Please refer to fig. 12, which is a diagram illustrating a drug name selection item display according to another embodiment of the present application. The processor 150 controls the medication name selection items 530 to be displayed in a tiled display in which the areas of different medication name selection items are independent of each other (as shown in fig. 11) or partially overlap (as shown in fig. 12). The processor 150 may retrieve the number of medication names stored in the data table and control the size of the area in which the medication name selection item 530 is located based on the retrieved number of medication names, so that the user can quickly select a medication name for the fluid in the infusion set from the tiled medication 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. When the number of the drug name selection items is greater than the preset threshold, the processor 150 controls the display screen 160 to display each drug name selection item in a display manner of a plurality of drug name setting interfaces 520; when the number of the drug name selection items is not greater than the preset threshold, the processor 150 controls each drug name selection item to be displayed in 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 selection items 530 are located according to the number of the medication name selection items 530 included in the medication name setting interface 520, such that the size of the area in which each medication name selection item 530 is located in the medication name setting interface 520 is maximized. For example, if the drug name selection item 530 has a corresponding preset threshold of 10, it indicates that one drug name setting interface 520 displays 10 drug name selection items 530 at most. When the data table for calling the drug names includes 6 drug names, the processor 150 may control the drug name setting interface 520 to display the drug name selection item 530 in 2 rows and 3 columns; when 10 drug names are included in the data table for calling drug names, the processor 150 may control the drug name setting interface 520 to display the drug name selection item 530 in 2 rows and 5 columns; when 5 drug names are included in the data table for calling 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 medication names are included in the data table for calling medication names, the processor 150 may display two medication name setting interfaces 520, where the first medication name setting interface 520 displays the medication name selection item 530 in 2 rows and 5 columns, and the second medication name setting interface 520 displays the medication name selection item 530 in 2 rows and 3 columns. When there are multiple medication name selection items in the medication name setting interface 520 display data tables, the processor 150 may display a multi-screen icon 552 (shown in fig. 16) on the medication name setting interface 520, and the user may toggle through the multiple medication name setting interface 520 by a particular gesture operation on the display screen 160, wherein the particular gesture operation includes, but is not limited to, a left swipe, a right swipe, a down swipe, an up swipe, a single click, or a multi-finger click, etc.

On the premise that the size of the display screen 160 is fixed, when the number of the medicine name selection items included in the medicine name setting interface is different, the size of the area where each medicine name selection item is located is different. Thus, when the number of the drug name selection items included in the drug name setting interface reaches a certain value, the area of the drug name setting interface 520 in which each drug name selection item is located becomes small. If the medication name setting interface 520 displays the medication name selection item in 1 row and 5 columns or 2 rows and 5 columns, the size of the area where the medication name selection item displayed in 2 rows and 5 columns is located may be smaller than that displayed in 1 row and 5 columns. Therefore, the area where the medicine name selection item is located becomes small, when the user selects the medicine name selection item, a plurality of medicine name selection items can be selected at the same time, and further the possibility of wrong selection exists. To facilitate user selection from the plurality of medication name selections 530, the processor 150 controls the medication name selections 530 to be displayed in partially overlapping tiles to increase the area of the medication name selections 530, wherein when the medication name selections are displayed in the partially overlapping tiles, there is a partial overlap between the areas of the different medication name selections, and for example, when the medication name setting interface 520 including 10 medication name selections is displayed, the processor 150 may display the medication name selections in 1 row and a plurality of rows without displaying the medication name selections in 2 rows and 5 columns. The processor 150 may control the area where the drug name selection item 530 located at one side is completely displayed, and the areas where the other drug name selection items 530 are located are displayed to overlap with each other (as shown in fig. 14); alternatively, the processor 150 may control the areas where the medication name selection items 530 located on the non-two sides are completely displayed, and the areas where the other medication name selection items 530 are located are displayed to overlap with each other (as shown in fig. 12). For example, when 8 medication names are included in the data table of the called medication names, if the medication names are displayed in a tiled manner, the processor 150 controls the medication name setting interface 520 to display the medication 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 medication name selection item 530 in the size of the area in which the medication name selection item 530 is displayed in 1 row and 5 columns. The user may also select by gesture operation when selecting the corresponding medication name selection item 530.

Fig. 13 is a schematic view showing a change of switching display of a drug name selection item in a drug name setting interface according to an embodiment of the present application. When the drug name setting event is detected, the processor 150 acquires or calls the data table of the drug names, and then controls the drug name selection items 530 contained in the data table of the drug names to be displayed in the drug name setting interface 520 in a tiled manner with a single drug name selection item, for example, if one drug name selection item 530 is displayed, the other drug name selection items 530 may be hidden behind the displayed drug name selection item 530. If the user needs to check 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, and at this time, the processor 150 detects a display switching event of the drug name setting interface. The processor 150 responds to the switch display event and adjusts the tiles of the individual medication name selections to be independent tiles.

Fig. 14 is a schematic view showing a variation of the switching display of the drug name selection item in the drug name setting interface according to another embodiment of the present application. In the medication name setting interface 520, the processor 150 may control the medication name selection item 530 to be tiled with a single medication name selection item. Compared with the embodiment corresponding to fig. 13, in this embodiment, when the processor 150 detects the display switching event of the medication name setting interface, the processor 150 adjusts the tile display mode of the single medication name selection item to a partially overlapping tile display mode.

Please refer to fig. 15, which is a diagram illustrating a drug name selection item display according to another embodiment of the present application. Each drug name in the data table of drug names stored in the memory 104 further has a corresponding category attribute, that is, each drug name has corresponding category information, wherein each category is classified according to that the drug infusion function satisfies a preset condition, and the category information includes, but is not limited to, a "common" category, a "sedation" category, a "analgesia" category, a "muscle relaxation" category, and "other" categories, so that the drug names satisfying the common function can be classified into the "common" category, the drug names satisfying the sedation function can be classified into the "sedation" category, the drug names satisfying the analgesia function can be classified into the "analgesia" category, the drug names satisfying the muscle relaxation function can be classified into the "muscle relaxation" category, and the drug names satisfying the other functions can be classified into the "other" categories. The processor 150 retrieves the drug names in the data table of drug names and displays the drug names according to the category information included in the data table of drug names. 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 a 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 screen 160 includes 5 drug name setting sub-interfaces 524, where the "commonly used" drug name setting sub-interface 524 corresponds to the "commonly used" 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 relaxant" drug name setting sub-interface 524 corresponds to the "muscle relaxant" category, and the "other" drug name setting sub-interface 524 corresponds to the "other" category.

In this embodiment, the processor 150 displays each medication name setting sub-interface 524 within the display screen 169 in the form of tab pages, where the tab name of each tab page is the corresponding category information. As such, the user may select the corresponding medication name settings sub-interface 524 based on the label name of the label page. The processor 150 may display the corresponding medicine name setting sub-interface 524 according to a switching event (e.g., a touch operation of selecting a corresponding tab page) for switching the medicine name setting interface. For example, if the currently displayed interface of the display screen 160 is the "commonly used" drug name setting sub-interface 524, if the processor 150 receives that the user clicks the "analgesia" tab, the processor 150 determines that a switching event is received, and at this time, the processor 150 responds to the switching event and controls the display screen 160 to display the "analgesia" drug name setting sub-interface 524. In one embodiment, the processor 150 defaults to displaying the "commonly used" medication name setting sub-interface 524 when detecting a medication name setting event, so that the user can quickly select a medication name of the "commonly used" category from the "commonly used" medication name setting 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" drug name setting sub-interface 524 is currently displayed, if an input operation of sliding left or other gesture input by the user is received, indicating that the user needs to view the next drug name setting sub-interface, at this time, the processor 150 controls the display screen 160 to display the "muscle relaxation" drug name setting sub-interface 524; if the user further enters a swipe left input operation or other gesture, the processor 150 may control the display screen 160 to display an "other" medication name setting sub-interface 524. If an input operation or other gesture of sliding 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-boundary of the current medication name setting sub-boundary, the processor 150 controls the display screen 160 to display the "muscle relaxation" 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 high-low manner or a random manner. The processor 150 may control the display of the selected medication name selection item 530 in the medication name setting sub-interface 524 based on the different display modes. The display modes include, but are not limited to, the aforementioned various tile display modes.

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

Please refer to fig. 15 and 16, wherein fig. 16 is a schematic diagram illustrating a drug name query operation according to an embodiment of the present application. Also included within the display screen 160 is a query trigger area 522, and the processor 150 may control the display screen 160 to display a separate query interface (or query area) 550 when the query trigger area 522 is triggered. 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 receiving 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 the drug name selection items 530 corresponding to the clicked query identifier exceeds a certain number, the processor 150 further controls the query interface 550 to display the multi-screen identifier 552, so that the user can switch through gesture operation. In this embodiment, since the query interface 550 is displayed as a separate interface, when the user wants to return to the medication name setting interface 520, the user may click the "return" button in the function selection area 526. If the user selects the determined medication name selection 530 at the query interface 550, the processor 150 may control the display screen 160 to display the infusion parameter setting interface 510 corresponding to the determined medication name selection 530. In an embodiment, the query identifier may correspond to the category information corresponding to the drug name, and thus, each query identifier may also have color information consistent with the corresponding category information, for example, the query identifier corresponding to the common "category has a first color, the query identifier corresponding to the" sedation "category has a second color, the query identifier corresponding to the" analgesia "category has a third color, the query identifier corresponding to the" muscle relaxation "category has a fourth color, and the query identifier corresponding to the other" category has a fifth color, so that when the user clicks the query identifier of the corresponding color, the user may query the drug name corresponding to the corresponding selected color.

Please refer to fig. 17, which is a schematic diagram illustrating a drug name query operation according to another embodiment of the present application. When the query trigger area is triggered, the processor 150 may control the drug name setting interface 520 in the display screen 160 to display the query area 554, where the query area 554 may also display a virtual keyboard, and the virtual keyboard may include a plurality of keys, and a first key corresponds to a query identifier. When the medication name setting interface 520 does not have a query trigger region, the user may also enter a specific gesture operation at the medication name setting interface 520 to bring up the query region 554 or the query interface 550. As shown in fig. 9, the user may input a three-finger down-slide gesture in the display screen 160, and when the processor 150 receives the gesture, the query area 554 shown in fig. 15 or the query interface 550 shown in fig. 14 may be called.

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

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

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

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

Fig. 18 is a schematic view of a parameter option interface corresponding to a name of a target drug in an embodiment of the present application. Upon detection of a triggering event based on the drug name selection item, it indicates that the user has determined the drug of the fluid in the infusion set. The user also needs to set or determine the related infusion parameter content during the infusion operation. In this embodiment, the processor 150 displays a corresponding preference interface 570 according to the name of the target drug, wherein the preference interface 570 includes information related to the flow rate, infusion mode, preset volume, and expected time when the infusion operation is initiated. Since the content of the infusion parameter corresponding to each drug name may be different, in order to facilitate the user to save the time of the infusion preparation process, the content of the infusion parameter corresponding to each drug name may be pre-stored in the memory 104. In one embodiment, the preset infusion parameter content may be set based on the infusion parameter content used by the corresponding medication name during the historical infusion operation. In this manner, the processor 150 may retrieve the contents of the infusion parameters preset in the memory 104 corresponding to the target medication target from the memory 104 and display the contents in the parameter option 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 infusion parameter content set in the infusion parameter setting interface 510 at the corresponding location 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 for 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 for the flow rate in the preference interface 570 to A. In one embodiment, the user may also modify the infusion parameter content of the flow rate at the parameter options interface 570.

And 108, driving the driving mechanism to move according to the content of the infusion parameters so as to enable the liquid in the injector to move according to the infusion direction.

In this embodiment, the user determines that the relevant infusion parameter content in parameter options interface 570 is correct, and the user may trigger the "start" button in function selection field 526. The processor 150 may receive an instruction to initiate an infusion. In other embodiments, the processor 150 may receive an instruction to initiate an infusion sent by the Dock processor (Dock). For example, multiple syringe pumps and/or infusion pumps may be connected in Dock and may be used to sequentially perform infusion/injection operations for respective set medications in a predetermined order. Dock may send an initiate infusion instruction to a corresponding syringe pump according to a sequence of infusion operations of the plurality of syringe pumps. For patient safety considerations, infusion operation of an infusion pump/syringe pump arranged in the first position requires confirmation by the healthcare worker and a priming operation on the pump; upon detecting that an infusion operation of an infusion pump/syringe at a first location is complete or is about to complete, the Dock processor may send a start infusion instruction to an infusion pump/syringe at a second location subsequent to the first location in the order of the infusion operation, thereby causing the infusion pump/syringe at the second location to perform the start infusion operation upon receiving the start infusion instruction sent by the Dock.

Referring to fig. 7, in the present embodiment, a plurality of display screens 160 may be disposed on the pump door 112 of the syringe pump 10, for example, a first display screen and a second display screen are disposed, wherein the first display screen is used 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 the second display screen is used 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 button area 514, and a switch button 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 518 to have a first color information (e.g., green); upon completion of the infusion operation, the processor 150 may control the progress bar display 518 to have a second color information (e.g., red); when the syringe 60 is not disposed in the syringe pump 10 and the syringe 10 is not operating for an infusion, the processor 150 may control the progress bar display 518 to have a third color information (e.g., gray).

Referring to FIG. 19, a schematic view 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 and a second display screen, wherein the first display screen is used 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 the second display screen is used 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 button area 515, and a switch button area 517. During an infusion operation by the peristaltic squeezing mechanism 200, 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 (e.g., green); upon completion of the infusion operation, the processor 150 may control the progress bar display 519 to have information in a second color (e.g., red); when the infusion pump 20 is not performing an infusion operation and the syringe 60 is not disposed in the infusion pump 20, the processor 150 may control the progress bar display 519 to have a third color information (e.g., gray).

In one embodiment, the processor 150 may display a tubing guidance interface on the display screen, including but not limited to the set direction of the infusion set, the attention required for setting, etc., when the infusion pump 100 is turned on or during the infusion set replacement or before the infusion set is in place, so as to facilitate the user to accurately set the infusion set. In other embodiments, the processor 150 may control the first display screen to display the tubing guide interface when or before detecting that the set state of the infusion set in the infusion pump 100 is detected as normal.

In one embodiment, a display screen 160 is provided on the pump door 112, such that the infusion parameter setting interface 510 and the function operation interface 512 can be provided in different sections of the display screen 160.

Because the screen of the existing infusion pump is small, the name of the drug can be selected only after the selection of the name of the drug needs to be performed through a plurality of steps of up-and-down selection OR entering a sub-menu and the like through keys, and for the case that the emergency treatment needs to be performed on the patient (such as departments such as an ICU (intensive care unit), an OR (OR operation OR department) and the like), when the number of operation steps is large when the name of the drug is selected, a long waiting time is caused, so that the time before the infusion is started is longer, and even the treatment of the patient can be influenced. According to the infusion pump control method, the medicine name setting interface is displayed after the medicine name setting event is detected, the medicine name setting interface comprises the medicine name selection items obtained from the infusion pump local machine or from a plurality of channels such as a network and the like, and the medicine name selection items are displayed in a tiled display mode, so that a user can conveniently and quickly select the medicine name in the displayed medicine name setting interface. The method and the device reduce the defect that the name of the drug can be possibly carried out after a user needs to go through a plurality of operation steps in the prior art, and are also beneficial to reducing the preparation time of the infusion operation. In addition, aiming at the condition of the injection pump, the injection pump controls the display screen to display the infusion parameter setting interface or the medicine name setting interface when detecting that the pump door is closed and the injector is arranged in the injection pump, so that the defect of waste of infusion time caused by pushing the piston handle after waiting for the push-pull mechanism to run for the preset time and then displaying the infusion parameter setting interface can be reduced. The infusion pump control method detects and can input and/or confirm infusion parameters through the infusion parameter device interface and simultaneously control the action of the push-pull mechanism, so that the infusion pump control method is also beneficial to reducing the time of infusion preparation operation.

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 (tubing/syringe), and the functions and component composition associated with the infusion pump 100 can be seen in the foregoing embodiments. The docking station 70 includes a docking station processor, a network interface, a peripheral interface, etc., 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 drug name options transmitted from the server through the network interface. The docking processor may parse the received order information to obtain a plurality of medication name selections. The docking processor also transmits the obtained plurality of medication name selections to each infusion pump 100.

When receiving the plurality of drug name selection items transmitted by the docking station processor, each infusion pump 100 displays a drug name setting interface on the corresponding display screen, where the drug name setting interface includes the plurality of drug name selection items, and areas where different drug name selection items are located are independent of each other or partially overlapped, and the drug name selection items are used for presenting drug names included in the order information.

For example, the order information received by the docking station 70 contains 6 drug name options, respectively "sufentanil", "epinephrine", "octreotide", "sodium nitroprusside", "cediland", and "dopamine". If the first infusion pump, the second infusion pump and the third infusion pump are connected to the docking station 70, when the first infusion pump, the second infusion pump and the third infusion pump receive the names of the drugs transmitted by the docking station 70, the first infusion pump, the second infusion pump and the third infusion pump all display a drug name setting interface including the 6 drug name selection items 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 contained in the order information transmitted by the server to the dock 70 may be the same as the number of infusion pumps 100 connected to the dock 70.

The user may input a trigger event of a drug name selection item in a drug name setting interface of one of the 3 infusion pumps (e.g., a first infusion pump), and the processor of the first infusion pump may determine a target drug name corresponding to the selected drug name selection item and determine corresponding infusion parameter content according to the target drug name. For example, when the user selects the "sufentanil" drug name selection item 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. Then, when the user clicks a 'start' button in the parameter selection interface, the processor of the first infusion pump receives a user instruction, and the processor of the first infusion pump drives the driving mechanism of the first infusion pump (or triggers the infusion pump) to move according to the corresponding infusion parameter content, so that the liquid in the syringe of the first infusion pump moves 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 name information of the target medication to the processor of the docking station 70. Since the medication name selection item in the order information is selected, it is indicated that the other infusion pumps may not need to use the selected medication name selection item. The docking station 70 may adjust the medication name setting interfaces in the other infusion pumps to remove the medication name selection item corresponding to the selected target medication name from the medication name setting interfaces in the other infusion pumps. For example, the docking station 70 may control the second and third infusion pumps to remove the "sufentanil" drug name option from the respective drug name setting interfaces, which now include only the remaining 5 drug name options.

In this embodiment, during the infusion operation of the first infusion pump, the user may select the corresponding drug name selection item on the drug name setting interfaces of the second infusion pump and the third infusion pump. For example, the user may select the drug name selection item for "epinephrine" at the second infusion pump, at which point the docking station 70 may control the third infusion pump to remove the drug name selection item for "epinephrine" from its own drug 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 the second infusion pump which initiates an infusion operation upon receiving the infusion initiation command. Likewise, 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, which initiates an infusion operation upon receiving the infusion initiation command.

In one embodiment, the patient may need to enter the same medication via multiple infusion pumps, and as such, the order information includes two or more of the same medication names. When the same medication name is selected by the user in the display screen of one infusion pump, the docking station 70 controls the medication name setting interfaces of the other infusion pumps to reduce the number corresponding to the same medication name by one or remove one, and the user can select another one or more of the same medication names in the display screens of the other infusion pumps.

The infusion pump system displays the drug name setting interface after detecting the drug name setting event, so that a user can conveniently and quickly select the drug name in the displayed drug name setting interface, and the infusion pump system is favorable for reducing the time of infusion operation preparation. In addition, the infusion pump system can control the starting infusion operation of a plurality of infusion pumps through the connecting dock, can set other infusion pumps during the infusion period of one infusion pump, and can reduce the preparation time of the infusion operation.

In the foregoing embodiments, the descriptions of the respective embodiments have respective emphasis, and for parts that are not described in detail in a certain embodiment, reference may be made to related descriptions of other embodiments.

In the embodiments provided in the present application, it should be understood that the disclosed apparatus may be implemented in other manners.
