Description

MEDICAL PUMP SYSTEM, MEDICAL PUMP CONTROL METHOD, MEDICAL PUMP CONTROL PROGRAM, AND MEDICAL PUMP

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

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, administration rate, and the like.
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 when the tube is bent or twisted during the administration of the drug solution.
If the medical pump continues to feed the drug solution even during the occlusion, the pressure increases in the tube, and therefore, the drug solution may be rapidly sent to the patient when the occlusion is released.
Therefore, for example, in a syringe pump, when the blockage sensor detects blockage, a proposal has been made to alleviate the pressure increase by causing the motor to reversely rotate without continuously feeding liquid (for example, Patent Document 1). etc).

JP 2002-113099 A

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 chemicals sent by each medical pump are not sent separately to the patient via needles, catheters, etc., and finally through the co-infusion unit, into one tube, In many cases, each chemical is sent.
In addition, since each of the plurality of medical pumps has a separate occlusion sensor, a difference in pressure detection accuracy, a difference in occlusion determination setting, and the like are generated by each occlusion sensor.

When such a medical pump administers a drug solution to a patient or the like with a single tube via a co-infusion unit, when the tube is clogged, the timing for determining the clogging for each medical pump is different. There is a fear. That is, a certain medical pump detects a blockage and reversely operates (operates) the motor, while another medical pump continues to execute a liquid feeding operation.
In this case, there is a possibility that the following problems may occur in the “mixed injection portion” to which each tube that stores the chemical solution sent by each medical pump is connected.
In other words, there is a problem that a “suction phenomenon” occurs in which the chemical liquid or the like of the medical pump that is continuously performing liquid feeding is sucked through the “mixed part” to the medical pump that is performing the reverse rotation 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 chemical solution is sucked from one medical pump to another medical pump, and the control of the medical pump It is an object to provide a method, a control program for a medical pump, and a medical pump.

In the present invention, the above object is provided with a plurality of medical pumps that control the liquid to be provided to the subject, and the medical pump moves at least the liquid in the pipe portion that stores the liquid. And a liquid moving part capable of detecting the in-pipe state information that is state information in the pipe part, and the pipe parts respectively disposed in the plurality of medical pumps. Is configured so that the liquids that are merged at the merging unit and the liquids contained therein are merged, and a blockage determination unit that generates blockage information of the tube unit based on the state information in the tube unit And the liquid moving part is configured to be switchable between a liquid feeding mode for moving the liquid in the pipe part in the liquid feeding direction and a counter liquid feeding mode for moving in the counter liquid feeding direction. The liquid delivery module It is configured to change to the operation of the reaction liquid feeding mode based on the blockage information, and the blockage information is configured to be notified to the other medical pumps. This is achieved by the medical pump system that is characterized.

According to the said structure, the pipe part each arrange | positioned at several medical pumps merges by a merge part (for example, "mixed injection part" etc.), and the liquid accommodated in each inside merges It has become.
That is, even if the liquid moving part of one medical pump operates in the liquid feeding mode and then changes to the operation in the counter liquid feeding mode based on the blockage information of the blockage determination part, the other medical pumps do not feed liquid. If the operation of the mode is still executed, there may be a “suction phenomenon” in which one medical pump sucks the liquid sent by another medical pump through the junction.
In this regard, in the above configuration, after the liquid moving unit operates in the liquid feeding mode, the liquid moving unit is configured to change to the operation in the counter liquid feeding mode based on the blockage information of the blockage determination unit. It is the structure notified to.
Therefore, the other medical pumps that have received the occlusion information can stop the liquid feeding mode, so that one medical pump causes the liquid moving unit to execute in the operation of the counter liquid feeding mode. However, it is possible to prevent the occurrence of a “suction phenomenon” that sucks the liquid on the other side of the medical pump.
Further, since the operation in the liquid feeding mode is executed, it is possible to prevent the occurrence of a situation in which the liquid is suddenly fed from the tube portion to the patient or the like when the blocked state is resolved.

Preferably, the liquid moving unit is configured to change to the operation in the counterfeed mode after the blockage information is notified to the other medical pump.

According to the above configuration, the liquid moving unit is configured to change to the operation in the counter-feeding mode after the blockage information is notified to the other medical pumps. Even if the moving unit is executed in the operation of the liquid feeding mode, it is possible to more reliably prevent the occurrence of the “suction phenomenon” in which the liquid on the other medical pump side is sucked.

Preferably, a management device capable of communicating with the medical pump is provided, and the blockage information is notified from the management device to another medical pump.

According to the said structure, it has the counter liquid feeding mode stop information generation part which produces | generates the counter liquid feeding mode stop information which is the stop information of counter liquid feeding mode based on the pipe state state information.
Therefore, since the liquid feeding mode stop information is generated based on the in-pipe state information, the reverse liquid feeding mode can be stopped at an appropriate timing. It is possible to prevent the liquid from being fed with higher accuracy and to appropriately manage the amount of the chemical liquid flowing out.

Preferably, the state information in the pipe part is pressure value information in the pipe part which is a pressure value in the pipe part, and when the pressure value information in the pipe part corresponds to information indicating a block state in the pipe part, And the expected liquid amount information corresponding to the pressure value in the pipe portion that stores the information on the expected staying liquid amount that is retained by the reaction liquid supply mode stop information generation unit based on the expected staying liquid amount information. The liquid mode stop information is generated.

According to the above-described configuration, the reaction liquid supply mode stop information generation unit generates the reaction liquid supply mode stop information based on the expected liquid amount information (for example, the assumed chemical liquid amount). The counter liquid feeding mode is executed only for the amount of information on the expected staying liquid amount.
Accordingly, when the occlusion state is resolved, it is possible to prevent the drug solution or the like from being rapidly sent from the pipe part to the patient, and to appropriately manage the amount of the drug solution flowing out.

Control method Then, after the liquid moving unit operates in the liquid feeding mode, the liquid moving unit is changed to the operation in the counter liquid feeding mode based on the blockage information, and the blockage information is notified to the other medical pumps. This is achieved by a method for controlling a medical pump system, characterized in that

Pump identification numbers (for example, “A-1” to “A-4” and “B-1” to “B-4” are stored in association with “communication addresses”.
Specifically, it is stored in the “server-side pump information storage unit 311” in FIG.

Thereby, the management server 300 can identify and manage the infusion pump 10 and the syringe pump 500 in the hospital and can communicate with each other.

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

Next, proceed 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) shown in FIG. 9 (the same applies to the syringe pump 500 (B-1)).

Next, proceed to ST3. In ST3, the “infusion line identification number transmission processing unit (program) 58” of FIG. 9 operates and refers to the “pump-side pump information storage unit 57”, and when the “infusion line identification number” is stored, The “infusion line identification number”, for example, “C-1” is transmitted as the “infusion line identification number” to the management server 300 and the own “pump identification number (A-1, B-1, etc.)” Are also transmitted to the management server 300.

Next, proceed to ST4. In ST4, the management server 300 receives the “infusion line identification number (C-1)” and “pump identification numbers (A-1, B) received from the infusion pump 10 (A-1) and the syringe pump 500 (B-1). -1), the “infusion line identification number (C-1)” is stored in the “infusion 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 included. Identified and stored.
Therefore, the management server 300 can accurately grasp and manage which infusion pump 10 or the like is located in which infusion line.

The preparation for administration of the drug solution is thus completed, and the drug solution administration process and the like will be described below with reference to FIG.
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 drug solution of the two drug bags 12 a and 12 b is administered to the patient P. The following description is based on an example in which the downstream blockage sensor 17 of the infusion pump 10 detects the 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 chemical liquids to be administered to a patient P are accommodated in two chemical liquid containers 12 a and 510, and pump side tubes 11 a and 11 b are connected to the respective chemical liquid containers 12 a and 510. These pump side tubes 11 a and 11 b are connected to the mixed injection part 13.
As a result, the two pump- side tubes 11 a and 11 b are connected to one patient-side tube 14 via the mixed portion 13.
Further, the patient tube 14 is connected to the patient P through the indwelling needle 15.

In this state, in ST11 of FIG. 13, data of “scheduled liquid feeding amount information” that is a scheduled liquid feeding 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, although the infusion pump 10 will be mainly described in the present embodiment, the same software configuration is also mounted on the syringe pump 500.
Specifically, the data of the “scheduled delivery amount information” is stored in the “infusion pump side scheduled delivery amount information storage unit 51” of the infusion pump 10 of FIG.

Next, in ST12, the infusion pump 10 and the syringe pump 500 operate to start the liquid feeding mode, for example, liquid feeding, and proceed to ST2. In ST2, the infusion pump 10 and the syringe pump 500 are operated to start feeding the liquid medicine 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, measurement of “occlusion detection pressure” that is state information in the pipe portion in 11a and the like is started.

Next, the process proceeds to ST13 and ST14. In ST13, the “integrated liquid feeding amount information calculation processing unit (program) 52” in FIG. 9 operates and refers to the “liquid feeding amount reference information storage unit 53” in FIG. In the liquid supply amount reference information storage unit 53, “liquid supply amount reference information” that is the relationship information between the rotational speed of the drive motor 18 and the liquid supply amount, that is, how many times the drive motor 18 rotates. Information about whether the amount of liquid to be fed is stored.

Therefore, the integrated liquid supply amount information calculation processing unit (program) 52 obtains the “integrated liquid supply amount information” of the infusion pump 10 from the predetermined “liquid supply amount reference information” and the “rotation amount” information of the drive motor 18. The calculated value is stored in the “integrated liquid feeding amount information storage unit 54” in FIG. 9 (the same applies to the syringe pump 500).
As described above, the cumulative liquid supply amount information storage unit 54 stores information on the cumulative liquid supply amount of the chemical solution such as the infusion pump 10.

On the other hand, in ST14, the infusion pump 10 stores the occlusion detection value of the “downstream occlusion sensor 17” in the “downstream occlusion detection value storage unit 55” in FIG. 5 (in the syringe pump 500, the “occlusion detection of the occlusion sensor 519”. Value ").
Next, the process 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 the “infusion pump blockage reference value information storage unit 56” in FIG. 9 is referred to.
At this time, different numerical values may be stored in the infusion pump 10 and the syringe pump 500 in FIG. 1, and this case corresponds to this case.

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

Therefore, the infusion pump 10 determines that the “downstream side occlusion detection value” exceeds the occlusion reference value based on the “downstream 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 blocking detection value” reaches “30 kPa”.

On the other hand, the syringe pump 500 in FIG. 5 determines whether or not the detection value of the “occlusion sensor 519” has reached “60 kPa”.

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

At this time, since the detection value of the “occlusion sensor 519” has not reached “60 kPa”, the syringe pump 500 of FIG. 5 is not yet judged to be obstructed, and the “occlusion flag” is not attached.

Next, proceed to ST18. In ST18, when the “pump blockage alarm information transmission processing unit (program) 61” of FIG. 10 is operated and the “blockage flag” is added to the “downstream blockage detection value storage unit 55”, the blockage information is, for example, “Blockage alarm information” is transmitted to “Management server 300” together with “Pump identification number (A-1)” of “Pump-side pump information storage unit 57” in FIG.

Next, proceed to ST19. In ST19, the management server 300 refers to the “server-side pump information storage unit 311” in FIG. 7, and transmits “blocking alarm information” “pump identification number”, for example, “blocking alarm information” for “A-1”. The presence information is stored.

Next, proceed to ST20. In ST20, the “server side blockage alarm information transmission processing unit (program) 312” of FIG. 7 operates and the pump identification number of the infusion pump 10 in which the “blockage alarm” of the “server side pump information storage unit 311” is stored. Identify the infusion line identification number of “A-1”, eg “pump identification number” of another pump associated with “C-1”, eg, syringe pump 500 (B-1), The alarm target pump storage unit 313 is stored.

Next, proceed to ST21. In ST21, the management server 300 sets the “communication address” corresponding to the “pump identification number (B-1)” of the “blockage alarm target pump storage unit 313” and the “server side pump information storage unit 311” in FIG. Acquired and transmits a “blocking alarm” to the syringe pump 500 (B-1) to notify that fact.

Next, proceed to ST22. In ST22, the syringe pump 500 (B-1) that has received the “blocking alarm information” from the management server 300 stops the drive motor and stops the liquid feeding operation.

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

For this reason, even if the infusion pump 10 (A-1) performs the reverse rotation operation, the medicinal solution of the syringe pump 500 (B-1) arranged in the same infusion line (C-1) passes through the co-injection unit 13. Thus, it is possible to reliably prevent the “suction phenomenon” from being sucked by the infusion pump 10 (A-1).
In particular, according to the present embodiment, the management server 300, not the infusion pump 10, performs management such as transmission of “blocking alarm information” and the like, so that another syringe pump 500 belonging to the same infusion line (C-1). It is possible to reliably transmit “blocking alarm information” or the like.

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

First, ST24 and ST25 are executed. In ST24, the “reverse operation integrated liquid feed amount information calculation processing section (program) 63” in FIG. 10 operates, and “liquid feed amount reference information” in the “liquid feed amount reference information storage section 53” in FIG. The “reverse operation integrated liquid supply information” which is the amount of the chemical solution integrated by the reverse operation of the infusion pump 10 is calculated from the “rotation amount” of 18 and the like, and “reverse operation integrated liquid supply information storage” of FIG. Part 64 ".

In ST25, the infusion pump 10 continues to store the blockage detection value of the downstream blockage sensor 17 in the “downstream blockage detection value storage unit 55” of FIG.
Next, in ST26, the “infusion pump blockage elimination determination processing unit (program) 65” of FIG. 10 operates and is based on the “downstream side blockage detection value storage unit 55” and the “infusion pump blockage relaxation reference value information storage unit 67”. Then, it is determined whether or not the “downstream blockage detection value” is equal to or less than the blockage relaxation 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 in the pump side tube 11a or the like due to the bending of the patient side tube 14 has increased is eliminated.

Next, when it is determined in ST27 that the downstream blockage detection value is equal to or less than the blockage relaxation 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.

Next, the process proceeds to ST29. In ST29, when the “infusion pump reverse rotation operation stop processing unit (program) 66” in FIG. 10 operates and the “downstream blockage detection value storage unit 55” in FIG. 9 is flagged, the infusion pump 10 is driven. The reverse rotation operation of the motor 18 is stopped.
Accordingly, when the reverse operation of the drive motor 18 is stopped together with the removal of the blockage, and the blockage state of the pump side tube 11a and the like is resolved, the liquid medicine is prevented from being rapidly sent from the patient side tube 14 to the patient P. In addition, the amount of the chemical liquid flowing out can be made appropriate.

However, if it is determined in ST27 that the pressure in the pump side tube 11a or the like has not increased, the process proceeds to ST30. In ST30, the “scheduled liquid delivery amount arrival determination processing unit (program) 71” in FIG. 11 operates to operate the “reverse operation integrated liquid feed amount information storage unit 63” in FIG. 10 and “infusion pump side scheduled liquid feed in FIG. With reference to the “volume information storage unit 51”, it is determined whether or not the “reverse operation integrated liquid supply amount” has reached the “infusion pump side planned liquid supply amount”.

That is, when the movement of the chemical liquid 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, so it is determined whether or not this situation occurs.

Therefore, when it is determined in ST31 that the “reverse operation integrated liquid supply amount” has reached the “infusion pump side planned liquid supply amount”, the process proceeds to ST32 and the reverse operation of the drive motor 18 of the infusion pump 10 is stopped. .
Thereby, when the obstruction | occlusion state is eliminated, it is possible to prevent the drug solution from being rapidly sent from the patient-side tube 14 to the patient P, and to make the amount of the drug solution flowing out appropriate.

On the other hand, if the “reverse operation integrated liquid supply amount” does not reach the “infusion pump side planned liquid supply amount” in ST31, the process proceeds to ST33.

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

Specifically, it is information on the estimated amount of the chemical solution measured in advance through experiments or the like. In addition, this estimated chemical | medical solution amount is an example of anticipated staying liquid amount information. Further, the occlusion detection value corresponding chemical liquid amount information stored in the occlusion detection value corresponding chemical liquid amount information storage unit 73 is an example of the expected liquid amount information corresponding to the in-pipe pressure value.

Therefore, in ST33, the assumed chemical liquid amount corresponding to the detected occlusion value is acquired from the “occluded detection value corresponding chemical liquid amount information storage unit 73” and stored in the “assumed chemical liquid amount information storage unit 74” of FIG.

Next, proceed to ST34. In ST34, for example, the “anticipated liquid amount determination processing unit (program) 75” which is the counter liquid supply mode stop information generation unit of FIG. 11 operates, and the “reverse operation integrated liquid supply amount information storage unit 64” of FIG. It is determined whether or not the “reverse operation integrated liquid supply amount” has reached the “assumed chemical liquid amount” in the “assumed chemical liquid amount information storage unit 74” of FIG.

That is, in the blockage detection value, the drive motor 18 is reversely operated by the amount of the chemical liquid actually retained in the pump side tube 11a or the like, so that it is effectively retained in the pump side tube 11a or the like. The chemical solution can be returned to the chemical solution container 12a side.
In addition, when the occluded state is resolved, it is possible to prevent the drug solution from being rapidly sent from the patient side tube 14 to the patient P.

Therefore, when it is determined in ST35 that the “reverse operation integrated liquid supply amount” has reached the “assumed drug solution amount”, the process proceeds to ST36 and the reverse operation of the drive motor 18 of the infusion pump 10 is stopped.

The present invention is not limited to the above-described embodiment and the like.

It also includes the case where the role of That is, the “management apparatus” in the present invention includes not only the management server 300 but also a rack.
In addition, the present invention may be configured such that a plurality of infusion pumps 10 and the like, the syringe pump 500 and the like communicate directly without using the management server 300 or a rack.
