Only when the previous operation meets the requirements can the next operation be performed, and finally the infusion can be started. The overall preparation time is relatively long. Especially when emergency treatment is required for patients, such a long preparation time may even affect the patient's treatment. Summary of the invention

The displacement sensor 106 can be inductive, capacitive, ultrasonic or Hall type.

[0046] The light assembly 168 may include a visual alarm element for indicating that the injection pump 10 is in an abnormal state. The light assembly 168 responds to the drive of the processor / controller 150 alone; the light assembly 168 may also cooperate with the speaker 154 to respond to the drive of the processor / controller 150, for example, the color or brightness of the light changes with the tone and frequency of the alarm sound. The light assembly 168 may include indicator lights of components such as the power supply and CPU, or an infusion fault status alarm light. The light assembly 168 may also include a visual lighting element for facilitating the observation of the structure or component status of the injection pump 10 when the ambient light is poor.

[0050] The communication module 172 facilitates communication with other devices via one or more external ports 122 , and it also includes various software components for processing data received by the RF circuitry 120 and / or the external ports 122 .

[0051] In one embodiment, the touch module 174 can selectively detect contact with the display screen 160 or other touch-sensitive devices (e.g., touch buttons, touch pads). For example, the touch module 174 detects contact with the display screen 160 together with the display controller 140. The touch module 174 includes various software components for performing various operations associated with the detection of contact with the display screen 160 (which can be performed by a finger or a touch pen, etc.), such as determining whether contact occurs (e.g., detecting the time when a finger is pressed), determining the strength of the contact (e.g., the force or pressure of the contact), determining whether the contact moves (e.g., detecting one or more finger drag events), or tracking the movement on the display screen and determining whether the contact stops (e.g., detecting the time when the finger is lifted or the contact is disconnected). The operation of determining the movement of the contact point can include determining the rate (amplitude), speed (amplitude and direction) and / or acceleration (including amplitude and / or direction) of the contact point. These operations can be applied to single-point contact or multi-point simultaneous contact. In one embodiment, the touch module 174 detects contact with other touch devices in conjunction with the display controller 140.

[0052] The touch module 174 can be used to detect gesture input by the user. Different gestures of the user on the touch-sensitive device have different contact patterns (for example, one or more combinations of the location, time or intensity of the contact are detected). For example, detecting a single-finger tap gesture includes detecting a finger press event, and then detecting a finger lift event at the same or similar position as the finger press event. For example, detecting a finger swipe gesture on the surface of the touch device includes detecting a finger press event, then monitoring one or more finger drag events, and then detecting a finger lift event. Similarly, taps, swipes, drags and other gestures of the touch pen are optionally detected by detecting a specific contact pattern of the touch pen.

[0053] The tactile feedback module 176 includes various software components for generating instructions to generate tactile outputs at one or more locations of the syringe pump 10 using one or more tactile output generators (not shown) in response to the user's interaction with the syringe pump 10.

Each graphic can be assigned a corresponding code. The graphics module 182 receives one or more codes for specifying graphics to be displayed from an application, etc., and also receives coordinate data and other graphics attribute data together when necessary, and then generates screen image data to output to the display controller 140.

The drug setting 194-4 may include an interface for providing a user to input different drug names, drug abbreviations, and / or drug colors, and the drug parameters are set before infusion by inputting the corresponding drug name / abbreviation / color, so as to facilitate automatic confirmation inside the syringe pump 10 or verification by medical staff during the infusion process. The volume setting 194-5 allows the user to adjust the volume of the alarm and / or other audio outputs as required. The brightness setting 194-6 allows the user to adjust the brightness of the screen, alarm light, lighting, etc. as required. The online setting 195-7 provides an input interface for the user to control whether the injection pump 10 and other devices are online, the online working mode, etc. as required.

When the syringe 60 is arranged in the syringe pump 10, the user can rotate the clamping handle mechanism 118 to the second state to press the syringe body 602 onto the pump body 110 of the syringe pump, and the flange 604 of the syringe 50 is received in the receiving groove 116 of the pump body 110, and the distance between the piston handle 606 and the push block 1140 is a preset distance d (shown in Figure 6 ).

[0061] 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 first position sensor disposed in the pump door 112, wherein the state of the pump door 112 includes an open state and a closed state. Figure 2 As shown, the processor 150 can determine that the pump door 112 is in an open state by setting a first position sensor. Figure 6 , which is a schematic diagram showing a state in which the pump door of the injection pump in one embodiment of the present application is closed. Figure 6 As shown, the processor 150 can determine that the pump door 112 is in the closed state through the first position sensor.

[0062] In this embodiment, a second position sensor is disposed in the clamping handle mechanism 118. When the syringe 60 disposed in the injection pump 10 is pressed onto the pump body 110 of the injection pump 10, the clamping handle mechanism 118 is in the second state, and at this time, the second position sensor can transmit a feedback signal. Therefore, the processor 150 can detect whether the syringe 60 is disposed in the injection pump 10 through the second position sensor. For example, when the syringe 60 is disposed in the injection pump 10, the clamping handle mechanism 118 fixes the syringe body 602 on the pump body 110, and the second position sensor can output a feedback signal. In this way, the processor 150 can confirm that the syringe body 602 of the syringe 60 is pressed onto the pump body 110 of the injection pump 10. In other embodiments, a pressure sensor can be disposed in the clamping handle mechanism 118, that is, when the syringe 60 is pressed onto the pump body 110 of the injection pump 10, the pressure sensor can 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 in the syringe pump 10 onto the pump body 110 of the syringe pump 10 according to the received feedback signal having pressure information.

[0063] In this embodiment, a third 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. At this time, the third position sensor can also output a feedback signal. Thus, when the processor 150 receives the feedback signal output by the third position sensor, the processor 150 can confirm that the flange 604 of the syringe 60 is received in the receiving groove 116.

[0064] Furthermore, the processor 150 can detect the state of the pump door 112 according to the first position sensor, and can also detect the setting state of the syringe 60 according to the second position sensor and the third position sensor. In this embodiment, when the second position sensor and the third position sensor both transmit feedback signals to the processor 150, the processor 150 can determine that the setting state of the syringe 60 is normal; when the processor 150 does not receive the feedback signal transmitted by any of the second position sensor and the third position sensor, the processor 150 can determine that the setting state of the syringe 60 is abnormal. For example, when the processor 150 receives the feedback signal transmitted by the second position sensor but does not receive the feedback signal transmitted by the third position sensor, it means that the flange 604 of the syringe 60 is received in the receiving groove 116, and then the setting state of the syringe 60 is detected to be abnormal; when the processor 150 receives the feedback signal transmitted by the third position sensor but does not receive the feedback signal transmitted by the second position sensor, it means that the user has not turned the clamping handle mechanism 118 to the second state, and the clamping handle mechanism 118 has not fixed the syringe body 602 on the pump body 110, and then the processor 150 can also detect that the setting state of the syringe 60 is abnormal. When the processor 150 determines that the setting state of the syringe 60 is abnormal, it controls the display screen 160 to output a prompt message that the setting state of the syringe 60 is abnormal. The processor 150 can also control the light assembly 168 to output a prompt message that the setting state of the syringe 60 is abnormal through the light controller 148.

[0065] In one embodiment, if the pump door 112 is in a closed state and the syringe 60 is not provided in the syringe pump 10, the syringe pump 10 may be in a shutdown state or a standby state. If the user uses the syringe pump 10 to perform the 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 through the first position sensor, the processor 150 controls the syringe pump 10 to power on or perform a startup operation, so that the syringe pump 10 is in a startup state. During the period when the user sets the syringe 60 (i.e., the period from when the processor 150 detects that the pump door 112 is opened to when the pump door 112 is closed), the syringe pump 10 may perform a self-test operation to detect the device status of the syringe pump 10. Among them, the self-test operation of the syringe pump 10 includes but is not limited to sound self-test, processor self-test, external storage device self-test, alarm light self-test, power supply self-test, and sensor self-test. When performing a sound self-test, the processor 150 can control the speaker 154 to make a sound through the audio circuit 124, and can determine whether the sound self-test has passed through the recording device; if the processor receives the sound made by the speaker 154 through the recording device, it can be determined that the sound self-test has passed, otherwise, it indicates that the device state of the injection pump 10 is abnormal. When performing a processor self-test, the processor 150 can run the preset program in the memory 104, and determine whether the result obtained after running the preset program is the preset result; if the result obtained after treating the preset program is the preset result, it can be determined that the processor self-test has passed, otherwise, it indicates that the device state of the injection pump 10 is abnormal. In addition, the processor 150 can also detect the external storage device, the light component 168, the power system 106 and multiple sensors. When each self-test operation passes, it can be determined that the device state of the injection pump 10 is normal; when there is at least one self-test operation that fails, it is determined that the device state of the injection pump 10 is abnormal, and a prompt message of abnormal device state can be output through the display screen 160 or the light component 168.

[0066] Since the existing technical solution may perform a self-check operation before setting the syringe 60 in the syringe pump 10, that is, the pump door 112 is opened and the syringe 60 is set in the syringe pump 10 after the syringe pump 10 completes the self-check operation, thereby increasing the time of the infusion task preparation stage (or the infusion operation preparation stage) to a certain extent. In this embodiment, when the pump door 112 is opened, the syringe pump 10 is turned on, and the self-check operation is performed simultaneously during the process of setting the syringe 60 in the syringe pump 10, that is, the self-check operation of the syringe pump 10 and the setting of the syringe 60 are processed in parallel, which is conducive to reducing the time of the infusion task preparation stage.

[0067] In other embodiments, the syringe pump 10 may include a power button (including but not limited to a physical button or other types of buttons), and when the power button is triggered, the user can open the pump door 112 to place the syringe 60 in the syringe pump 10. Afterwards, the syringe pump 10 also performs a self-check operation while placing the syringe 60 in the syringe pump 10, which can also achieve the purpose of reducing the time of the infusion task.

[0068] Step 143, when it is detected that the pump door is closed and the setting state of the syringe in the injection pump is normal, control the display screen to display the infusion parameter setting interface.

[0069] In this embodiment, when the processor 150 detects that the pump door 112 is closed and the setting state of the syringe 60 in the syringe pump 10 is normal, the processor 150 can control the display screen 160 set 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, and the infusion parameter setting items are used to present one or more infusion parameter contents, including but not limited to infusion parameter contents such as infusion speed and infusion volume. When the pump door 112 is closed and the setting state of the syringe 60 in the syringe pump 10 is normal, there is a preset distance d between the push block 1140 of the push-pull mechanism 114 and the piston handle 606. Therefore, when the driving mechanism 133 controls the push-pull mechanism 114 to start the infusion operation, the driving mechanism 133 needs to move the push block 1140 toward the piston handle 606 by the preset distance d, so that the push block 1140 and the piston handle 606 are against (or in contact with) each other, and then the processor 150 performs the infusion action (or infusion operation) according to the set infusion parameter contents. Since the existing technical solution may control the display screen 160 to display the infusion parameter device interface 510 after the push block 1140 and the piston handle 606 are in contact, and it takes a certain amount of time for the push block 1140 to move a preset distance and contact the piston handle 606, this will also increase the time of the infusion preparation stage.

[0070] Please also read Figure 7 , which is a schematic diagram of the state in which the push-pull mechanism abuts against the piston handle in an embodiment of the present application. In this embodiment, when the setting state of the syringe 60 in the syringe pump 10 is normal, the processor 150 controls the display screen 160 to display the infusion parameter setting interface 510, and at the same time, the processor 150 drives the driving mechanism 133 to operate at the first motor speed, driving the propulsion mechanism 114 to move in the direction of the piston handle 606 of the syringe 60. After the driving mechanism 133 operates at the first motor speed for a preset time, the propulsion mechanism 114 abuts against the 606 piston handle. In this way, the user controls the action of the push-pull mechanism 114 while performing the infusion parameter setting through the infusion parameter device interface 510, which is also conducive to reducing the time of the infusion operation.

[0071] Step 145: driving the driving mechanism to move according to at least one of the infusion parameter contents, so that the liquid in the syringe moves in the infusion direction.

[0072] In this embodiment, when the propulsion mechanism 114 presses against the piston handle 606, the injection pump 10 can enter the stage of starting the infusion operation, and the processor 150 can drive the driving mechanism 133 to move at a second motor speed according to at least one infusion parameter content, and control the piston handle 606 of the syringe 60 and the syringe body 602 to move relative to each other, so that the liquid in the syringe 60 moves in the infusion direction.

[0073] In this embodiment, the pump door 112 may be provided with a plurality of display screens 160, for example, a first display screen and a second display screen, wherein the first display screen is used to display an infusion parameter setting interface 510, and the second display screen is used to display a function operation interface 512. Figure 7 As shown, the functional 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, it indicates that the injection pump 10 is performing an infusion operation. At this time, the processor 150 can control the progress bar display area 518 to have a first color information (such as green); when the infusion operation is completed, the processor 150 can control the progress bar display area 518 to have a second color information (such as red); when the injection pump 10 is not performing an infusion operation and the syringe 60 is not provided in the injection pump 10, the processor 150 can control the progress bar display area 518 to have a third color information (such as gray).

[0074] The user can set or operate the content in the infusion parameter device interface 510 by triggering the menu button area 514, and can determine whether to start the infusion operation. For example, when the user sets the infusion parameter device interface 510, the processor 150 is used to detect the trigger event of the user on the infusion parameter setting interface 510, and adjust the infusion parameter content based on the trigger event. When the driving mechanism 133 drives the push-pull mechanism 114 to move a preset distance d at the first motor speed and contacts the piston handle 606, if the user is still adjusting the infusion parameter content, at this time, the driving mechanism 133 can pause driving the push-pull mechanism 114, and after the user completes the setting and starts the infusion instruction, the processor 150 drives the driving mechanism 133 to move according to the infusion parameter content to start the infusion operation. In this embodiment, the infusion instruction is generated when the user triggers the start button after setting the infusion parameter content, or the start infusion instruction can be sent by the Dock. For example, multiple injection pumps may be connected to the Dock, and the multiple injection pumps can be used to perform injection operations of multiple drugs in sequence. The dock can send a start infusion instruction to the corresponding syringe pump according to the order of the infusion operation of the multiple syringe pumps. When it is detected that the infusion operation of the syringe pump at the first position is completed or about to be completed, the dock can send a start infusion instruction to the syringe pump at the second position after the first position in the order of the infusion operation, so that the syringe pump at the second position performs the start infusion operation after receiving the start infusion instruction sent by the dock. The user can complete the start, shutdown or standby action of the syringe pump 10 by triggering the switch button area 516. In one embodiment, a pressure sensor can be provided on the push block 1140, so that when the push block 1140 blocks the piston handle 606, the pressure sensor provided on the push block 1140 can output a feedback signal with pressure information to the processor 150, so that when the processor 150 determines that the feedback signal transmitted by the pressure sensor provided on the push block 1140 is received, it can determine that the push block 1140 is against the piston handle 606. In this way, when the processor 150 receives the feedback signals output by the second position sensor, the third position sensor and the pressure sensor arranged on the push block 1140, and when the processor 150 receives the start infusion instruction after the user sets the infusion parameter content, the processor 150 can control the speed of the second motor of the driving mechanism 133 according to the set infusion parameter content to continue the infusion operation.

[0075] Please also read Figure 8, which is a schematic diagram of the syringe pump in one embodiment of the present application when starting the infusion operation. In this embodiment, the push-pull mechanism 114 is used to clamp the piston handle 606 of the syringe 60. The processor 150 in the syringe pump 10 issues instructions such as rotation speed or position, and drives the power device (such as the drive mechanism 133) through the power drive circuit 130. The drive mechanism 133 drives the screw rod 135 and the nut 137 through the reduction mechanism, and converts the rotational motion of the drive mechanism 133 into the linear motion of the nut 137. The nut 137 is connected to the connecting rod 1142 of the syringe pump 10, and the connecting rod 1142 is connected to the push block 1140. The push block 1140 can push the piston handle 660 of the matching syringe 60 for injection and infusion. The driving mechanism 133 can adjust its propulsion speed for the matching syringe 60 through the rotation speed (such as the second motor speed), thereby adjusting the given infusion dose and infusion speed.

[0076] In one embodiment, when the syringe pump 10 is turned on or when the syringe 60 is replaced, the processor 150 may display a tube installation guide interface on the first display screen, including but not limited to the setting direction of the syringe 60, matters needing attention during setting, etc., so as to facilitate the user to accurately set the syringe 60. In other embodiments, the processor 150 may control the first display screen to display the tube installation guide interface when or before the setting state of the syringe 60 in the syringe pump 10 is detected to be normal.

[0077] In one embodiment, a display screen 160 is disposed on the pump door 112 , and thus, the infusion parameter setting interface 510 and the function operation interface 512 can be disposed in different partitions of the display screen 160 .

[0078] In one embodiment, after detecting the state of the pump door 112 and the setting state of the syringe 60 in the syringe pump 10, the processor 150 may determine the preset amount information of the liquid in the syringe 10. For example, the processor 150 determines the preset amount information of the liquid in the syringe 10 during the period from when the pump door 112 is detected to when the pump door 112 is detected to when the pump door 112 is closed. The processor 150 may detect the outer diameter information of the syringe 60 and the length information of the liquid in the syringe 60 in the length direction of the piston handle 606 of the syringe 60 through a sensor, and then determine the preset amount information of the liquid in the syringe 60 based on the outer diameter information and the length information. In other embodiments, the user may also set the preset amount information in the infusion parameter setting interface 510.

[0079] During the infusion operation, the liquid in the syringe 60 gradually decreases, and the processor 150 can also determine the volume information of the infused liquid and the remaining volume information of the liquid in the syringe 60 according to the action of the driving mechanism 133. The processor 150 can also determine the infusion progress information according to the remaining liquid volume information and the infusion parameter content, such as determining the remaining infusion time. The processor 150 also controls the display screen 160 to display the infusion progress information.

[0080] At present, the syringe pump adopts a serial design in the preparation workflow before starting the infusion. After starting the machine, it will perform a self-test, and only after the self-test is successful will it start to identify the syringe status; when the user opens the pump door to install the syringe, the push-pull mechanism will be pulled open, and the infusion parameter setting interface will be set on the screen for the user to edit or confirm after the syringe is successfully set in the syringe pump and the push-pull mechanism is successfully clamped with the piston handle. In the middle, the time for the push-pull mechanism to clamp with the piston handle from the farthest point can take tens of seconds. This process is very long, and the user can only wait, which is very unreasonable.

[0081] The above-mentioned syringe pump control method is conducive to reducing the time spent on the infusion task by processing the self-check operation of the syringe pump and the setting of the syringe in parallel. In addition, when the syringe pump detects that the pump door is closed and the setting state of the syringe in the syringe pump is normal, the control display screen displays the infusion parameter setting interface, which can also reduce the waste of infusion time caused by waiting for the push-pull mechanism to run for a preset time and then displaying the infusion parameter setting interface after the piston handle is pressed. The above-mentioned syringe pump control method detects and can control the action of the push-pull mechanism while the infusion parameters are input and / or confirmed through the infusion parameter device interface, which is also conducive to reducing the time of the infusion operation. In order to ensure the safety of the use of the syringe pump, the user can only start the infusion after the push-pull mechanism and the piston handle are clamped correctly and the infusion parameters of the syringe pump are set. This effectively shortens the user's waiting time and does not damage the safety of the use of the syringe pump.
