First, it is stated that the term "and/or" appearing herein is merely one type of associative relationship that describes an associated object, meaning that three types of relationships may exist, e.g., a and/or B may mean: a exists alone, A and B exist simultaneously, and B exists alone. In addition, the character "/" herein generally indicates that the former and latter related objects are in an "or" relationship.

It should be noted that the terms "first," "second," and the like in the description and claims of the present invention and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or otherwise described herein.

The infusion control system provided by the embodiment of the invention can be arranged in a ward and used for controlling the infusion process of a patient, and of course, can also be arranged in other places with infusion requirements, such as an operating room or an ambulance.

Referring to fig. 1, an infusion control system according to an embodiment of the present invention includes: a main control device 100, a bubble monitoring device 200 and an infusion regulating device 300. Wherein, the bubble monitoring device 200 is electrically connected with the main control device; the infusion adjusting device is electrically connected with the main control device.

Specifically, the bubble monitoring device 200 is configured to monitor whether a bubble is present in the infusion tube, and feed back an alarm signal to the main control device 100 when the bubble is detected. The main control device 100 is used for sending a blocking instruction to the infusion regulating device 300 when receiving the alarm signal; the main control device 100 is further configured to send a flow rate adjustment instruction to the infusion regulating device 300 when receiving a user operation signal.

For the bubble monitoring device 200, in a specific implementation process, the bubble monitoring device 200 may be a capacitive bubble detector or a photoelectric bubble detector, and certainly, in order to achieve a better bubble monitoring effect, the bubble monitoring device 200 may also be an ultrasonic bubble detector.

With respect to the infusion regulating device 300, specifically, referring to fig. 2, the infusion regulating device 300 includes a first pressing plate 301, a second pressing plate 302 and a pressing roller 303. The first pressing plate 301 is rotatably connected relative to the second pressing plate 302, and a structure for clamping the infusion tube is formed by matching the first pressing plate 301 and the second pressing plate 302; the pressing roller 303 is slidably provided on the second pressing plate 302.

In one aspect, when the infusion regulating device 300 clamps the infusion tube, the infusion regulating device 300 is configured to reduce an included angle between the first pressing plate 301 and the second pressing plate 302 to block air bubbles in the infusion tube when receiving a blocking command.

With continued reference to fig. 2, the first pressing plate 301 is provided with a first driving assembly 3011 and a rotating shaft 3012; the second pressing plate 302 is provided with a rotary shaft catching groove 3021 and a first rack 3022.

In a specific implementation process, the first pressing plate 301 of the infusion adjusting device 300 may be detached, an infusion tube to be controlled is placed between the first pressing plate 301 and the second pressing plate 302, the rotating shaft 3012 of the first pressing plate 301 is matched with the rotating shaft clamping groove 3021 of the second pressing plate 302, and the first driving assembly 3011 is engaged with the first rack 3022, so as to complete the setting of the infusion adjusting device 300.

Of course, before the infusion needle is not pricked into the skin of the patient, the infusion tube can pass through the structure of clamping the infusion tube between the first pressing plate 301 and the second pressing plate 302, and after the infusion adjusting device 300 is arranged, the infusion needle is pricked into the skin of the patient, so that the infusion adjusting device 300 does not need to be disassembled, and the time for disassembling and assembling the infusion adjusting device 300 is saved.

Based on the above arrangement of the infusion adjusting device 300, when the infusion adjusting device 300 receives a blocking instruction, the first driving assembly 3011 is controlled to move on the first rack 3022, so that the included angle between the first pressing plate 301 and the second pressing plate 302 is reduced to block air bubbles in the infusion tube.

In order to increase the torque output by the first drive assembly 3011 so that the included angle between the first pressing plate 301 and the second pressing plate 302 is as small as possible to better block air bubbles in the infusion tube, the first drive assembly 3011 includes: a first driving motor 3011a and a first worm 3011b, wherein the first worm 3011b is engaged with a first rack 3022. The first drive motor 3011a is configured to: executing corresponding driving action when responding to the blocking instruction; the first worm 3011b is configured to rotate by a driving operation of the first driving motor 3011a, and to move the first worm 3011b relative to the first rack 3022.

In a specific implementation, the driving action includes forward rotation or reverse rotation, and the first driving motor 3011a performs the forward rotation or the reverse rotation in response to the blocking instruction, which is determined by the meshing direction of the first worm 3011b and the first rack 3022. Since the worm drive itself can increase the output torque, the first worm 3011b can be directly provided on the rotation shaft of the first drive motor 3011 a. Of course, the torque output by the first drive assembly 3011 may be further increased by any one or more of:

the first method is as follows: the first drive motor 3011a is engaged with the first worm 3011b via a reduction gear (not shown).

The second method comprises the following steps: the first drive motor 3011a is a low-speed high-torque motor.

In addition, since the first worm 3011b can only be rotated by the first worm 3011b to move the first drive assembly 3011 relative to the first rack 3022 after the first worm 3011b is engaged with the first rack 3022, once the first worm 3011b stops rotating, the first drive assembly 3011 cannot move relative to the first rack 3022. Therefore, even if the first driving motor 3011a does not operate, the included angle between the first pressing plate 301 and the second pressing plate 302 does not change, so that the first driving assembly 3011 has an automatic locking function, and the situation that the included angle between the first pressing plate 301 and the second pressing plate 302 changes randomly when the first driving motor 3011a does not operate does not occur.

It should be noted that the included angle between the first pressing plate 301 and the second pressing plate 302 may be: the included angle between the upper surface of the first pressing plate 301 and the pressing roller 303; or the angle between the upper surface of the first pressing plate 301 and the upper surface of the second pressing plate 302.

The maximum included angle between the first pressing plate 301 and the second pressing plate 302 can be set according to the diameter of the infusion tube, the length of the first pressing plate 301, and the length of the second pressing plate 302, and the maximum included angle can be any angle between 0 ° and 90 °, for example, the maximum included angle can be 45 ° or 60 °. The minimum included angle between the first pressing plate 301 and the second pressing plate 302 can be set to 0 °, and the minimum distance between the first pressing plate 301 and the second pressing plate 302 can be set to twice the tube wall of the infusion tube.

On the other hand, when the infusion tube is held by the infusion adjustment device 300, the infusion adjustment device 300 may be configured to control the pressing roller 303 to roll with respect to the infusion tube to adjust the infusion flow rate when receiving the flow rate adjustment command.

As shown in fig. 2, the second pressing plate 302 is further provided with a pressing roller sliding groove 3023 and a second rack 3024; a second driving assembly 3031 is arranged on the compression roller 303, the compression roller 303 is arranged in the compression roller sliding groove 3023 in a penetrating manner, and the second driving assembly 3031 is meshed with the second rack 3024;

when the infusion adjustment device 300 receives a flow rate adjustment command after the infusion adjustment device 300 is set on the infusion tube, the second driving assembly 3031 is controlled to move on the second rack 3024, so that the pressure roller 303 can roll relative to the infusion tube to adjust the infusion flow rate.

In order to adjust the infusion flow, when the infusion adjusting device 300 receives a flow adjusting command, it is determined whether the included angle between the first pressing plate 301 and the second pressing plate 302 is 0 °.

Specifically, if the current included angle is 0 °, the first driving assembly 3011 is controlled to move on the first rack 3022 until the included angle between the first pressure plate 301 and the second pressure plate 302 increases to a preset angle, and then the second driving assembly 3031 is controlled to move on the second rack 3024, so that when the pressure roller 303 slides in the pressure roller sliding groove 3023, different degrees of pressure are generated on the infusion tube. The preset angle may be set according to the length of the pressing roller sliding groove 3023, for example, the preset angle may be 10 ° or 15 °, and for the sake of simplicity of the description, the preset angle is not illustrated in this embodiment.

If the current included angle is not 0 °, the second driving assembly 3031 is directly controlled to move on the second rack 3024, so that the pressure roller 303 generates different degrees of pressure on the infusion tube when sliding in the pressure roller sliding groove 3023.

In order to increase the torque output by the second drive assembly 3031, so that the pressure of the pressing roller 303 when pressing the infusion tube is as large as possible to achieve a wider range of infusion flow rate adjustment, as shown in fig. 5 to 6, the second drive assembly 3031 includes: a second drive motor 3031a and a second worm 3031b, wherein the second worm 3031b is engaged with the second rack 3024. The second drive motor 3031a is configured to: executing corresponding driving action when responding to the flow regulation instruction; the second worm 3031b is configured to rotate under the driving action of the second drive motor 3031a, so that the second worm 3031b moves relative to the second rack 3024.

In a specific implementation, the driving action includes forward rotation or reverse rotation, and the second driving motor 3031a performs the forward rotation or the reverse rotation in response to the flow rate adjustment command, which is determined by the meshing direction of the second worm 3031b and the second rack 3024. Since the worm drive itself can increase the output torque, the second worm 3031b can be directly provided on the rotation shaft of the second drive motor 3031 a. Of course, the torque output by the second drive assembly 3031 may be further increased by any one or more of the following:

the first method is as follows: the second drive motor 3031a is engaged with the second worm 3031b via a reduction gear (not shown).

The second method comprises the following steps: the second drive motor 3031a is a low-speed high-torque motor.

In addition, since the second drive assembly 3031 and the second rack 3024 can only be moved relatively by the rotation of the second worm 3031b after the second worm 3031b is engaged with the second rack 3024, once the second worm 3031b stops rotating, the second drive assembly 3031 cannot be moved relatively with the second rack 3024. Therefore, even if the second drive motor 3031a does not work, the compression roller 303 cannot slide freely in the compression roller sliding groove 3023 due to the resilience of the infusion tube, so that the second drive assembly 3031 has the function of automatic locking, and the situation that the compression roller 303 does not extrude the infusion tube when the second drive motor 3031a is not operated is avoided.

It will be appreciated that, because second drive assembly 3031 moves linearly and compression roller 303 moves rotationally relative to second drive assembly 3031, second drive assembly 3031 may be coupled to compression roller 303 via bearings (not shown) in order to achieve the above-described functionality of second drive assembly 3031.

In order to linearly move the second drive assembly 3031, a limit stop (not shown) may be provided on the second pressure plate 302 to linearly move the second drive assembly 3031 between the limit stop and the second rack 3024. Referring to fig. 2, a guide pin 3013 may be disposed on the first pressure plate 301, and correspondingly, a guide slot 3025 may be disposed on the second pressure plate 302, so that the first pressure plate 301 is more stable when rotating relative to the second pressure plate 302 by the cooperation of the guide pin 3013 and the guide slot 3025.

In order to prevent the first pressing plate 301 from being abnormally separated from the second pressing plate 302 during the normal operation of the infusion regulating device 300, a disengagement preventing pin may be provided in the rotating shaft catching groove 3021. Because the anti-slip pin can limit the radial movement of the rotating shaft 3012 after the rotating shaft 3012 is in clamping connection with the rotating shaft clamping groove 3021, the rotating shaft 3012 is prevented from slipping from the rotating shaft clamping groove 3021, and the normal operation of the infusion adjusting device 300 is ensured.

Although the air bubbles are blocked when the included angle between the first pressing plate 301 and the second pressing plate 302 is minimum, the infusion liquid is blocked, so that the infusion process is also interrupted, and the air bubbles in the infusion tube need to be removed to restore normal infusion.

Referring to fig. 7 to 8, when receiving the alarm signal, the main control device 100 may further determine whether the current included angle between the first pressing plate 301 and the second pressing plate 302 is 0 °, and if the current included angle is not 0 °, control the infusion adjusting device 300 to sequentially execute the following actions to eliminate the bubbles in the infusion tube:

the first action is as follows: by controlling the second drive assembly 3031, the platen roller 303 is moved to a position closest to the rotation axis 3012.

And the second action: by controlling the first driving assembly 3011, the included angle between the first pressing plate 301 and the second pressing plate 302 is 0 °.

And action three: by controlling the second drive assembly 3031, the platen roller 303 is moved to a position farthest from the rotary shaft 3012.

If the bubble monitoring device 200 detects a bubble during the first, second, and third actions, the bubble may be considered as a bubble removed by the infusion regulating device 300, and the bubble may flow back to the position of the bubble monitoring device 200, so that the bubble monitoring device 200 generates an erroneous alarm signal, and the main control device 100 may perform a masking process on the alarm signal to avoid sending an erroneous blocking instruction.

After the third action is executed, the following steps a1 to a2 are executed in a loop until the master control device 100 receives an error alarm signal:

step A1: by controlling the first driving assembly 3011, the included angle between the first pressing plate 301 and the second pressing plate 302 is increased.

Step A2: after the included angle is increased, the infusion regulating device 300 is controlled to sequentially execute the first action, the second action and the third action to remove the air bubbles in the infusion tube.

After the master control device 100 receives the error alarm signal, the first driving assembly 3011 is controlled to increase the included angle between the first pressing plate 301 and the second pressing plate 302 to resume the infusion.

Because the bubbles move to the upstream of the infusion tube under the action of self buoyancy and the extrusion force of the compression roller 303, the bubbles in the infusion tube cannot flow through the infusion adjusting device 300 and cannot enter the body of a patient, and the safety in the infusion process is ensured; after the main control device 100 receives an error alarm signal, the first driving assembly 3011 is controlled to increase the included angle between the first pressing plate 301 and the second pressing plate 302 to resume infusion, so that normal infusion is ensured, and bubbles are prevented from entering the body of the patient.

The operation speeds of the first drive assembly 3011 and the second drive assembly 3031 are set according to the infusion flow rate, and the operation speeds of the first drive assembly 3011 and the second drive assembly 3031 are both faster than the infusion flow rate. The faster the infusion flow rate, the faster the first drive assembly 3011 and the second drive assembly 3031 operate, to ensure that the infusion regulating device 300 can block air bubbles in a timely manner.

Specifically, the main control device 100 includes an operation button (not shown), a display interface (not shown), and a main board (not shown), wherein the operation button and the display interface are electrically connected to the main board, and the main board is electrically connected to the infusion regulating device 300. The operation button is used for generating a user operation signal according to user operation; the display interface is used for displaying information in the infusion process; the main board is used for processing the user operation signal to generate a flow regulation instruction and sending the flow regulation instruction to the infusion regulation device 300; and is also configured to process the alarm signal and send the blocking instructions to the infusion regulating device 300.

In the specific implementation process, the user can control the infusion speed by operating the buttons according to the actual infusion requirement. For example, if the patient feels good during the infusion process and wants to increase the infusion speed, the infusion speed can be appropriately increased by operating an increase button of the buttons.

It is understood that the user can set the volume of the infusion liquid by operating the buttons, so that the main control device 100 calculates the time required for the whole infusion process and the remaining infusion time according to the set volume of the infusion liquid and the current infusion speed. In addition, the main control device 100 controls the infusion regulating device 300 to make the current infusion speed not higher than the dangerous infusion speed, wherein the dangerous infusion speed can be set to any value of 40-80 drops per minute.

In a specific implementation process, the display interface may display the infusion information in a full-screen display manner, or may display the infusion information one by one in a round-screen display manner, where the infusion information may include a current infusion speed and a remaining infusion time.

When a patient needs to input various medicines, the infusion tube is often divided into a plurality of infusion bottles due to different input sequences of different infusion medicines, the infusion is carried out in a segmented infusion mode, and the corresponding infusion tube can be provided with a plurality of liquid inlet branch tubes; in addition, when the dosage of the medicine which needs to be input by the patient is large, the infusion is also carried out in a segmented infusion mode, and the corresponding infusion tube is also provided with a plurality of liquid inlet branch tubes.

Therefore, to control multiple infusion bottles, as an alternative embodiment, the infusion control system of the present invention may comprise a master control device 100 and multiple sets of infusion monitoring devices, wherein each set of infusion monitoring devices comprises a bubble monitoring device 200 and an infusion regulating device 300.

For the infusion tube with a plurality of liquid inlet branch tubes, the bubble monitoring device 200 in each group of liquid delivery control devices is used for monitoring whether bubbles exist in the corresponding liquid inlet branch tubes; the infusion regulating device 300 in each set of infusion control devices is used for regulating the infusion flow and/or blocking air bubbles in the liquid inlet branch pipe when the liquid inlet branch pipe is clamped.

Specifically, when the present invention is applied to an infusion tube having a plurality of inlet branch tubes, a set of infusion monitoring devices may be placed on each inlet branch tube, and the bubble monitoring devices 200 in each set of infusion monitoring devices correspond to the infusion regulating devices 300 one to one.

In the specific implementation process, the medical staff can select the number of the infusion monitoring devices to be connected to the main control device 100 according to the number of the infusion bottles, and after the infusion monitoring devices are arranged on the liquid inlet branch pipes of the infusion tube, a plurality of infusion bottles are connected to the infusion tube. Then, the infusion sequence of each set of infusion adjusting devices 300 is set according to the preset infusion sequence, so as to realize the infusion control of a plurality of bottle infusion bottles.

For example, if the patient needs to input the drugs in the infusion bottle a and the infusion bottle B in sequence, the medical staff can select two sets of infusion monitoring devices, and set one set of infusion monitoring devices on the liquid inlet branch pipe connected to the infusion bottle a and the other set of infusion monitoring devices on the liquid inlet branch pipe connected to the infusion bottle B, control the two sets of infusion monitoring devices to block the infusion flow, and then connect the infusion bottle a and the infusion bottle B with the corresponding liquid inlet branch pipes.

After the infusion bottle a and the infusion bottle B are connected, the main control device 100 controls the infusion monitoring device corresponding to the infusion bottle a to operate according to the infusion sequence set by the medical staff, and controls the infusion monitoring device corresponding to the infusion bottle B to be in a standby state. When the main control device 100 detects that the liquid in the infusion bottle a is exhausted, the infusion monitoring device corresponding to the infusion bottle B is controlled to work, and until the liquid in the infusion bottle B is exhausted, the corresponding infusion adjusting device 300 is controlled to block the infusion flow and generate an infusion completion signal, so that the sequential infusion control of the infusion bottle a and the infusion bottle B is realized, and the workload of medical staff is effectively reduced.

Specifically, whether the time length of the alarm signal sent by the corresponding bubble monitoring device 200 is longer than a preset time length or not can be judged, and if the time length is longer than the preset time length, the liquid in the infusion bottle can be judged to be exhausted; otherwise, it is determined as a bubble. The preset time is set according to the infusion flow rate, and the faster the infusion flow rate is, the shorter the preset time is.

In order to improve the efficiency of the setup process performed on the master control device 100, reduce the probability of errors in manual setup, and reduce the workload of medical personnel, the infusion control system may further include a scanning gun (not shown). The scanning gun is electrically connected with the main control device 100 and is used for scanning the target two-dimensional code to obtain infusion process data and feeding the infusion process data back to the main control device 100; the master control device 100 processes the infusion process data and controls at least one infusion regulating device 300 to perform corresponding actions.

In the specific implementation process, the target two-dimensional code can be a medical wrist strap on the hand of the patient or a two-dimensional code on an infusion bottle. Infusion process data may include: the infusion sequence of the infusion bottle, the volume of the infusion bottle, the infusion speed and the like.

As an optional implementation, the infusion control system may further include an alarm bracelet. The alarm bracelet is in communication connection with the main control device 100 and is used for executing an alarm action when receiving an alarm signal sent by the main control device 100.

In a specific implementation process, the alarm bracelet may be worn on a hand of a patient or a hand of a family member of the patient, and once the alarm signal sent by the master control device 100 is received, the alarm bracelet may perform one or more alarm actions of light flashing, vibration and alarm ringing.

In addition, when acquiring the infusion completion signal generated by the main control device 100, the alarm bracelet may execute an infusion completion prompt action different from the alarm action, so that the medical staff can know that the infusion is completed, and then perform the next operation.

In order to prevent one or more of the master control device 100, the bubble monitoring device 200 and the infusion regulating device 300 from being out of order and being unable to control the infusion process, and further improve the safety during the infusion process, the master control device 100 may be further connected to an alarm device of a nurse station through a network, so as to send an alarm signal, an infusion completion signal or a failure signal to the alarm device of the nurse station in time.

The technical scheme in the embodiment of the invention at least has the following technical effects or advantages:

1. in the infusion control system disclosed by the embodiment of the invention, the bubble monitoring device 200 is electrically connected with the main control device 100, so that whether bubbles exist in the infusion tube can be monitored, and an alarm signal is fed back to the main control device 100 when the bubbles exist. The main control device 100 is used for sending a blocking instruction to the infusion regulating device 300 when receiving the alarm signal; and is also used for sending a flow rate adjustment instruction to the infusion regulating device 300 when receiving a user operation signal. Because the infusion regulating device 300 is electrically connected with the main control device 100, when the infusion regulating device 300 clamps an infusion tube, the infusion regulating device 300 can control the pressing roller 303 to roll relative to the infusion tube when receiving a flow regulating instruction so as to regulate the infusion flow; the included angle between the first pressing plate 301 and the second pressing plate 302 can be reduced when the blocking instruction is received so as to block air bubbles in the infusion tube. When bubbles in the infusion tube are removed, the bubbles in the infusion tube are extruded by the compression roller 303 in a rolling manner, so that the bubbles can be prevented from entering the body of a patient, and the safety of the patient in the infusion process is improved. Meanwhile, the operation of medical personnel is reduced because the air exhaust is carried out without taking down the needle head of the infusion tube, thereby improving the efficiency of removing air bubbles in the infusion tube.

2. The infusion tube can adjust the infusion flow without directly contacting the liquid in the infusion tube, so that on one hand, the pollution to the infusion liquid is avoided, the risk of accidental infection of a patient is prevented, and the safety in the use process is improved; on the other hand, the infusion tube clamp device works in a mode of clamping the infusion tube, and the existing infusion tube is not required to be improved, so that the infusion tube clamp device can be applied to different types of infusion tubes, and the compatibility of different infusion tubes is improved.

3. The infusion control system disclosed by the embodiment of the invention can comprise a main control device 100 and a plurality of groups of infusion monitoring devices, wherein each group of infusion monitoring device comprises a bubble monitoring device 200 and an infusion regulating device 300. The number of the main control device 100 connected with the infusion monitoring devices can be determined according to the number of infusion bottles, and after the infusion monitoring devices are arranged on the liquid inlet branch pipes of the infusion tubes, the infusion sequence of each group of infusion adjusting devices 300 is controlled according to the preset infusion sequence, so that the infusion control of a plurality of bottle infusion bottles is realized, and the workload of medical staff is effectively reduced.
