Description

The present invention relates to, for example, a medical pump system for delivering a drug solution or the like to a patient, a medical pump control method, a medical pump control program, and a medical pump.

2. Description of the Related Art Conventionally, for example, when a drug solution is administered to a patient, a medical pump such as an infusion pump or a syringe pump has been used in order to accurately control the dose and the administration speed.
Such a medical pump administers a drug solution containing a drug or the like to a patient via a tube.
However, the tube may be blocked by bending or twisting during administration of the drug solution.
If the medical pump continues to deliver the drug solution even during this blockage, the pressure in the tube increases, so that the drug solution may be rapidly delivered to the patient when the blockage is released.
Therefore, for example, in a syringe pump, when the occlusion sensor detects occlusion, it is proposed that the pump does not continuously deliver the liquid and the motor is reversely operated to alleviate the increase in pressure (for example, Patent Document 1). etc).

Japanese Patent Laid-Open No. 2002-113099

By the way, a medical solution may be administered to a patient using a plurality of medical pumps. In this case, the tubes containing the drug solution to be delivered by the medical pumps are not separately delivered to the patient via the needles or catheters, etc., but finally into a single tube via the mixed injection unit, Often, each chemical solution is delivered.
Further, since the plurality of medical pumps each have a separate occlusion sensor, the occlusion sensors cause differences in pressure detection accuracy and occlusion determination settings.

When such a medical pump administers a drug solution to a patient or the like through a mixed injection part in a single tube, if a blockage occurs in the tube, the timing of determining the blockage differs for each medical pump. There is a risk. That is, a certain medical pump detects a blockage and operates (operates) the motor in reverse, but another medical pump continues to perform the liquid feeding operation.
In this case, the following problems may occur in the “mixed injection part” to which the tubes containing the drug solutions sent by the medical pumps are connected.
That is, there is a problem that a "suction phenomenon" occurs in which the chemical solution of the medical pump that is continuously delivering liquid is sucked through the "mixing section" to the medical pump that is performing the reverse operation. There is.

Therefore, the present invention provides a medical pump system capable of accurately preventing the occurrence of a "suction phenomenon" in which a liquid such as a drug solution is sucked from one medical pump to another medical pump, and a medical pump control. A method, a control program for a medical pump, and a medical pump are provided.

Is configured such that the liquids stored in the respective merging portions merge at the merging portion, and the clogging determination portion that generates clogging information of the pipe portion is generated based on the inside state information of the pipe portion. The liquid moving unit is configured to be switchable between a liquid feeding mode for moving the liquid in the pipe portion in the liquid feeding direction and a liquid feeding mode for moving the liquid in the liquid feeding direction in the anti liquid feeding direction. After operating in the liquid delivery mode, the section is configured to change to the operation in the anti-liquid delivery mode based on the blockage information, and the blockage information is notified to the other medical pump. It is achieved by a medical pump system characterized in that

According to the above-mentioned configuration, the pipe parts respectively arranged in the plurality of medical pumps merge at the confluence part (for example, the “mixed injection part” or the like), and the liquids contained in the respective confluences merge. Has become.
That is, even if the liquid moving unit of one medical pump operates in the liquid sending mode and then changes to the operation in the anti-liquid sending mode based on the blockage information of the blockage determining unit, the other medical pump does not transfer liquid. If the operation of the mode is still executed, there is a possibility that a "suction phenomenon" occurs in which one medical pump sucks the liquid sent by another medical pump through the merging portion,
In this regard, in the above configuration, the liquid moving unit is configured to change to the operation in the anti-liquid transfer mode based on the blockage information of the blockage determination unit after operating in the liquid transfer mode. It is configured to be notified to.
Therefore, the other medical pump that has received the occlusion information can stop the liquid delivery mode, which allows the one medical pump to operate the liquid moving unit in the anti-liquid delivery mode operation. Also, it is possible to prevent the occurrence of the "suction phenomenon" of sucking the liquid on the side of the other medical pump.
Further, since the operation in the anti-liquid transfer mode is executed, it is possible to prevent the situation where the liquid is rapidly transferred from the pipe portion to the patient or the like when the closed state is resolved.

It is possible to more accurately prevent the liquid from being sent, and it is possible to appropriately manage the amount of the chemical liquid flowing out.

Preferably, the pipe portion internal state information is pipe portion internal pressure value information that is a pressure value in the pipe portion, and when the pipe portion internal pressure value information corresponds to information indicating a closed state in the pipe portion, the blockage thereof. The anti-sending liquid mode stop information generation unit stores the expected staying liquid amount information corresponding to the in-pipe pressure value stored in the anti-sending device based on the expected staying liquid amount information. It is characterized in that the liquid mode stop information is generated.

According to the above configuration, the anti-liquid transfer mode stop information generation unit generates the anti-liquid transfer mode stop information based on the predicted liquid amount information (for example, the estimated chemical liquid amount, etc.), so that the anti-liquid transfer mode stop information stays in the pipe portion in the closed state. The anti-liquid transfer mode is executed only for the estimated accumulated liquid amount information.
Therefore, when the closed state is resolved, it is possible to extremely accurately prevent the drug solution or the like from being rapidly delivered to the patient from the tube portion, and it is possible to appropriately manage the amount of the drug solution flowing out or the like.

12 to 16 are schematic flowcharts showing main operation examples of the pump system 1 according to the present embodiment.
First, in step (hereinafter referred to as “ST”) 1 of FIG. 12, the management server 300 of FIG. 1 is provided with the management server 300 and the infusion pump 10 and the syringe pump 500 of FIG. A pump identification number (for example, "A-1" to "A-4" or "B-1" to "B-4" is stored in association with a "communication address").
Specifically, it is stored in the "server side pump information storage unit 311" of FIG.

As a result, the management server 300 can identify and manage the infusion pump 10 and the like in the hospital, the syringe pump 500 and the like, and can communicate with them.

In this state, for example, a nurse who is a medical worker uses the infusion pump 10 (A-1) and the syringe pump 500 (B-1) to administer two different drugs to the patient P. , Start preparation for administration.
Specifically, as shown in FIG. 5, the two drug solution containers 12a and 510, the pump side tubes 11a and 11b connected to these, and the mixed injection part 13 and the pipe part connected to the mixed injection part 13 are shown. For example, the infusion pump 10 (A-1) and the syringe pump 500 (B-1) are arranged in the "infusion line (infusion line identification number C-1)" including the patient side tube 14 and the like.

Then, it proceeds to ST2. In ST2, the "infusion line identification number (C-1)" is input to the infusion pump 10 (A-1) and the syringe pump 500 (B-1) by a nurse or the like. This infusion line identification number (C-1) is stored in the "pump side pump information storage unit 57" of the infusion pump 10 (A-1) (the same applies to the syringe pump 500 (B-1)) shown in FIG.

Then, it proceeds to ST3. In ST3, the “transfusion line identification number transmission processing unit (program) 58” in FIG. 9 operates, refers to the “pump side pump information storage unit 57”, and when the “transfusion line identification number” is stored, For example, “C-1” which is the “infusion line identification number” is transmitted to the management server 300 as the “infusion line identification number”, and at the same time, the “pump identification number (A-1, B-1, etc.) of its own”. Is also transmitted to the management server 300.

Then, it proceeds to ST4. In ST4, the management server 300 receives the “infusion line identification number (C-1)” and the “pump identification number (A-1, B) received from the infusion pump 10 (A-1) or the syringe pump 500 (B-1). Based on -1), the "transfusion line identification number (C-1)" is stored in the "transfusion line identification number" corresponding to the pump in the "server side pump information storage unit 311".

As described above, the “infusion line” shown in FIG. 5 is specified by the “infusion line identification number (C-1)” in the management server 300, and the infusion pump 10 and the syringe pump 500 included in the infusion line are also identified. It is specified and stored.
Therefore, the management server 300 can accurately grasp and manage which infusion pump 10 etc. is arranged in which infusion line.

With the above, the preparation for administration of the liquid medicine is completed, and hence the administration process of the liquid medicine will be described below with reference to FIG. 13 and the like.
In the present embodiment, as shown in FIG. 5, the same infusion line is formed using the infusion pump 10 and the syringe pump 500, and the patient P is administered with the drug solutions in the two drug bags 12a and 12b. The following description will be given based on an example in which the downstream blockage sensor 17 of the infusion pump 10 detects blockage of the pump side tube 11a before the blockage sensor 519 of the syringe pump.

First, as shown in FIG. 5, for example, different types of drug solutions to be administered to a patient P are contained in two drug solution containers 12a and 510, and pump-side tubes 11a and 11b are connected to the drug solution containers 12a and 510, respectively. These pump-side tubes 11a and 11b are connected to the mixed injection section 13.
As a result, the two pump-side tubes 11 a and 11 b are connected to the single patient-side tube 14 via the mixed portion 13.
The patient tube 14 is connected to the patient P via the indwelling needle 15.

In this state, in ST11 of FIG. 13, data of “planned liquid delivery amount information”, which is the planned liquid delivery amount of each drug solution to be administered to the patient P, is input to the infusion pump 10 and the syringe pump 500.
Hereinafter, in the present embodiment, the infusion pump 10 will be mainly described, but a similar software configuration is also installed in the syringe pump 500.
The data of the “planned liquid delivery amount information” is specifically stored in the “infusion pump side planned liquid delivery amount information storage unit 51” of the infusion pump 10 in FIG.

Next, in ST12, the infusion pump 10 and the syringe pump 500 are operated to start a liquid transfer mode, for example, liquid transfer, and the process proceeds to ST2. In ST2, the infusion pump 10 and the syringe pump 500 operate to start the delivery of the drug solution at a predetermined speed, and the “downstream occlusion sensor 17” of the infusion pump 10 and the occlusion sensor 519 of the syringe pump 500 are pump-side tubes. For example, the measurement of the "occlusion detection pressure", which is the internal state information of the pipe inside 11a or the like, is started.

Then, the process proceeds to ST13 and ST14. In ST13, the “integrated liquid delivery amount information calculation processing unit (program) 52” of FIG. 9 operates and refers to the “liquid delivery amount reference information storage unit 53” of FIG. The liquid feed amount reference information storage unit 53 stores “liquid feed amount reference information”, which is the relationship information between the rotation speed of the drive motor 18 and the liquid feed amount, that is, how many times the drive motor 18 rotates. Is stored.

Therefore, the integrated liquid delivery amount information calculation processing unit (program) 52 obtains the “integrated liquid delivery amount information” of the infusion pump 10 from the predetermined “liquid delivery amount reference information” and the “rotation amount” information of the drive motor 18. It is calculated and stored in the “accumulated liquid delivery amount information storage unit 54” in FIG. 9 (same for the syringe pump 500).
In this way, the cumulative liquid delivery amount information storage unit 54 stores information on the cumulative liquid delivery amount of the liquid medicine of the infusion pump 10 and the like.

On the other hand, in ST14, the infusion pump 10 stores the blockage detection value of the “downstream blockage sensor 17” in the “downstream blockage detection value storage unit 55” of FIG. 5 (in the syringe pump 500, “blockage detection of the blockage sensor 519”). Remember the value").
Then, it proceeds to ST15. In ST15, for example, the infusion pump blockage determination processing unit (program) 59, which is the blockage determination unit in FIG. 9, operates and refers to the “infusion pump blockage reference value information storage unit 56” in FIG.
At this time, different values may be stored in the infusion pump 10 and the syringe pump 500 in FIG. 1, and this case corresponds to this case in the present embodiment.

That is, for example, the syringe pump 500 sets “60 kPa” as the “blocking reference value” for determining the blockage, but the infusion pump 10 sets “30 kPa” as the “blocking reference value”.

Therefore, in the infusion pump 10, the "downstream side occlusion detection value" exceeds the occlusion reference value based on the "downstream side occlusion detection value storage unit 55" and the "infusion pump occlusion reference value information storage unit 56" in FIG. Determine whether or not.
That is, the infusion pump 10 determines whether or not the “downstream blockage detection value” has reached “30 kPa”.

On the other hand, the syringe pump 500 of FIG. 5 determines whether the detection value of the “occlusion sensor 519” has reached “60 kPa”.

Then, it progresses to ST16. In ST16, when the infusion pump 10 determines that the “downstream blockage detection value” has reached “30 kPa”, it determines that the “blocked state” has occurred, and proceeds to ST17.
In ST17, a "blocking flag" is attached in association with the corresponding detection value in the "downstream blockage detection value storage unit 55".

At this time, in the syringe pump 500 of FIG. 5, the detection value of the “occlusion sensor 519” has not reached “60 kPa”, so it is not yet determined to be occlusion and the “occlusion flag” is not added.

Then, it proceeds to ST18. In ST18, when the “pump side blockage alarm information transmission processing section (program) 61” of FIG. 10 operates and a “blockage flag” is added to the “downstream side blockage detection value storage section 55”, the blockage information is, for example, The "blockage warning information" is transmitted to the "management server 300" together with the "pump identification number (A-1)" in the "pump side pump information storage unit 57" of FIG.

Then, it progresses to ST19. In ST19, the management server 300 refers to the "server side pump information storage unit 311" in FIG. 7, and transmits the "blocking alarm information" to the "pump identification number", for example, "A-1" is the "blocking alarm information". Stores the existence information of.

Then, it progresses to ST20. In ST20, the pump identification number of the infusion pump 10 in which the "server side blockage alarm information transmission processing unit (program) 312" of FIG. 7 operates and the "blockage alarm" of the "server side pump information storage unit 311" is stored. The "A-1" infusion line identification number, for example, another pump associated with "C-1", for example, the "pump identification number" of the syringe pump 500 (B-1), is specified, and "blockage" is specified. It is stored in the alarm target pump storage unit 313”.

Then, it proceeds to ST21. In ST21, the management server 300 sets the "pump identification number (B-1)" in the "blockage warning target pump storage unit 313" and the corresponding "communication address" in the "server side pump information storage unit 311" in FIG. It acquires and transmits the "blocking alarm" to the syringe pump 500 (B-1), and notifies that effect.

Then, it progresses to ST22. In ST22, the syringe pump 500 (B-1) that has received the “blockage warning information” from the management server 300 stops the drive motor and stops the liquid feeding operation.

On the other hand, the infusion pump 10 in FIG. 5 proceeds to ST23. In ST23, when the “transfusion pump reverse operation processing unit (program) 62” of FIG. 10 operates and the “closed flag” is added to the “downstream blockage detection value storage unit 55”, the drive motor 18 of the infusion pump 10 Is a reverse liquid feeding mode, for example, reverse operation is performed.
This is a process for preventing the drug solution from suddenly flowing out from the patient side tube 14 to the patient P when the blockage of the pump side tube 11a or the like is eliminated.
In the present embodiment, even if this reverse operation is executed, the drive motor of the syringe pump 500 shown in FIG. 5 and the like is stopped in ST22 and the liquid supply is stopped.

Therefore, even if the infusion pump 10 (A-1) performs the reverse operation, the drug solution of the syringe pump 500 (B-1) arranged in the same infusion line (C-1) passes through the mixed injection unit 13. It is possible to reliably prevent the occurrence of the "suction phenomenon" of being sucked by the infusion pump 10 (A-1).
In particular, according to the present embodiment, since the management server 300, not the infusion pump 10, manages the transmission of the “blockage alarm information” and the like, the other syringe pump 500 belonging to the same infusion line (C-1). It is possible to reliably transmit the “blocking warning information” to the like.

As described above, in the present embodiment, the “suction phenomenon” in which the infusion pump 10 sucks the drug solution of the syringe pump 500 in the same infusion line can be prevented, but as described above, the pump side tube 11a or the like is blocked. When the problem is solved, it is necessary to prevent the drug solution from suddenly flowing out from the patient side tube 14 to the patient P, and to appropriately manage the amount of the drug solution flowing out and the like.
Therefore, in this embodiment, the following steps are executed.

First, ST24 and ST25 are executed. In ST24, the "reverse operation accumulated liquid delivery amount information calculation processing unit (program) 63" of FIG. 10 operates, and the "liquid delivery amount reference information" of the "liquid delivery amount reference information storage unit 53" of FIG. The "reverse operation accumulated liquid delivery amount information", which is the liquid delivery amount of the drug solution accumulated by the reverse rotation operation of the infusion pump 10 from 18 "rotation amount" and the like, is calculated, and the "reverse operation accumulated liquid delivery amount information storage of FIG. Section 64".

In ST25, the infusion pump 10 continues to store the occlusion detection value of the downstream occlusion sensor 17 in the “downstream occlusion detection value storage unit 55” in FIG.
Next, in ST26, the “transfusion pump blockage elimination determination processing unit (program) 65” in FIG. 10 operates, and based on the “downstream blockage detection value storage unit 55” and the “transfusion pump blockage mitigation reference value information storage unit 67”. Then, it is determined whether or not the “downstream blockage detection value” is less than or equal to the blockage mitigation reference value.
That is, it is determined whether or not the closed state generated in FIG. 5, for example, the state in which the pressure inside the pump side tube 11a or the like has increased due to the bending of the patient side tube 14 has been resolved.

Next, if it is determined in ST27 that the downstream blockage detection value is less than or equal to the blockage mitigation reference value, the process proceeds to ST28.
In ST28, a cancellation flag is attached in association with the corresponding detection value in the "downstream blockage detection value storage unit 55" in FIG.

Then, it proceeds to ST29. In ST29, when the “infusion pump reverse rotation stop processing unit (program) 66” in FIG. 10 operates and the “downstream-side blockage detection value storage unit 55” in FIG. The reverse rotation operation of the motor 18 is stopped.
Therefore, the reverse rotation of the drive motor 18 is stopped when the blockage is cleared, and when the blockage state of the pump-side tube 11a or the like is resolved, the drug solution is prevented from being rapidly sent from the patient-side tube 14 to the patient P. In addition to being able to do so, it is possible to make the amount of the chemical solution flowing out appropriate.

However, if it is determined in ST27 that the state where the pressure inside the pump side tube 11a or the like has increased has not been resolved, the process proceeds to ST30. In ST30, the “planned liquid delivery amount arrival determination processing unit (program) 71” in FIG. 11 operates, the “reverse operation cumulative liquid delivery amount information storage unit 63” in FIG. 10 and the “infusion pump-side planned liquid delivery in FIG. 9”. With reference to the "amount information storage unit 51", it is determined whether or not the "reverse operation cumulative liquid delivery amount" has reached the "infusion pump-side planned liquid delivery amount".

That is, when the movement of the liquid medicine in the direction opposite to the liquid feeding direction exceeds the planned liquid feeding amount of the infusion pump 10, it is not necessary to continue the reverse rotation operation, and therefore it is determined whether or not such a situation occurs.

Therefore, if it is determined in ST31 that the "reverse operation accumulated liquid delivery amount" has reached the "infusion pump-side planned liquid delivery amount", the process proceeds to ST32 and the reverse rotation operation of the drive motor 18 of the infusion pump 10 is stopped. ..
This can prevent the drug solution from being rapidly sent from the patient-side tube 14 to the patient P when the closed state is resolved, and can appropriately set the amount of the drug solution flowing out.

On the other hand, in ST31, when the “reverse operation accumulated liquid delivery amount” does not reach the “infusion pump side expected liquid delivery amount”, the process proceeds to ST33

In ST33, the “estimated discharged chemical liquid amount information generation processing unit (program) 72” in FIG. 11 operates to acquire the blockage detection value in the “downstream blockage detection value storage unit 55”. Then, the "liquid amount information storage unit 73 corresponding to the detected occlusion value" in FIG. 11 is referred to.
In the occlusion detection value-corresponding chemical liquid amount information storage unit 73, the assumed chemical liquid amount excessively accumulated in the pump side tube 11a or the like assumed by the occlusion detection value, that is, the occlusion state is released at the occlusion detection value. Information on the estimated amount of the chemical solution discharged from the pump side tube 11a or the like is stored in advance for each occlusion detection value.

Specifically, it is information on the estimated amount of chemical liquid measured in advance by an experiment or the like. The estimated amount of chemical liquid is an example of the estimated amount of staying liquid information. In addition, the blockage detection value corresponding chemical liquid amount information stored in the blockage detection value corresponding chemical liquid amount information storage unit 73 is an example of the pipe internal pressure value corresponding predicted liquid amount information.

Therefore, in ST33, the estimated drug solution amount corresponding to the detected occlusion value is acquired from the "occluded drug value corresponding drug amount information storage unit 73" and stored in the "estimated drug amount information storage unit 74" of FIG.

Then, it proceeds to ST34. In ST34, for example, the “supposed chemical liquid amount determination processing unit (program) 75” which is the anti-liquid transfer mode stop information generation unit of FIG. 11 operates, and the “reverse operation cumulative liquid transfer amount information storage unit 64” of FIG. It is determined whether or not the “reverse operation accumulated liquid delivery amount” has reached the “estimated liquid amount” of the “estimated liquid amount information storage unit 74” in FIG. 11.

That is, in the blockage detection value, the drive motor 18 is operated in the reverse direction by the amount of the drug solution that actually accumulates in the pump side tube 11a or the like, so that it effectively stays in the pump side tube 11a or the like. The drug solution can be returned to the drug solution container 12a side.
Further, it is also possible to prevent the drug solution from being rapidly delivered from the patient side tube 14 to the patient P when the closed state is resolved.

Therefore, when it is determined in ST35 that the “reverse operation cumulative liquid delivery amount” has reached the “estimated amount of liquid medicine”, the process proceeds to ST36, and the reverse operation of the drive motor 18 of the infusion pump 10 is stopped.
