Specifically, an infusion pump or the like is attached to a tube or the like of an infusion set, and the flow rate or the like of a chemical solution flowing through the tube is to be accurately controlled.

  Thus, the drip set, the syringe, the infusion pump, the syringe pump, and the like are intended to provide the patient with the drug solution at a desired flow rate by cooperating with each other. However, an infusion set or the like is disposable (disposal) every time, whereas an infusion pump or the like is not disposable. For this reason, it is difficult to always handle the infusion pump and the drip set as the same set product.

On the other hand, if a combination of various types of infusion pumps and the like, as well as various types of infusion sets, are used in any combination, there is a risk that the drug solution cannot be appropriately administered to the patient or the like due to a difference in the specifications.
Therefore, conventionally, an infusion pump or the like has been provided with an identification symbol or the like for specifying an infusion set or the like that can be used or recommended for use with the infusion pump, and the identification symbol or the like is stored in the infusion pump or the like. ing.

Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings.
The embodiments described below are preferred specific examples of the present invention, and thus various technically preferable limitations are given. However, the scope of the present invention is particularly limited in the following description. Unless otherwise stated, the present invention is not limited to these embodiments.

(First embodiment)
FIG. 1 is a schematic diagram showing the appearance of, for example, an infusion pump 1 that is a medical device having a medical device inspection mode, and FIG. 2 is a single-use (disposal) for each infusion mounted on the infusion pump 1 of FIG. It is the schematic which shows the tube set 100 for infusion pumps which is a medical device which is).
As shown in FIG. 2, the “infusion pump tube set 100” includes, for example, a “liquid feeding tube 120 for feeding a liquid medicine in the liquid infusion container 110 to a patient from a“ liquid container 110 ”that stores the liquid medicine. "have.

The liquid feeding tube 120 includes a hollow needle 121, a drip tube 122, a clamp 123 and the like directly connected to the infusion container 110.
And this liquid feeding tube 120 is mounted | worn with the inside of the infusion pump 1 as shown with the broken line of FIG.
FIG. 3 is a schematic view showing a finger part 30 for feeding a chemical solution in a flexible liquid feeding tube 120 mounted in the infusion pump 1, a cam shaft part 31 for operating the finger part 30, and the like. .

As shown in FIG. 3, the finger portion 30 has six fingers 30 a to 30 f, and these fingers 30 a to 30 f are sequentially closed or separated from the liquid feeding tube 120 according to the operation of the cam shaft portion 31. Operate.
Thus, the liquid feeding tube 120 is deformed so as to be sequentially closed and opened by the fingers 30a to 30f, and the chemical solution in the liquid feeding tube is fed. In addition, this liquid feeding can be controlled so that a predetermined flow rate is supplied at a predetermined time.

As shown in FIG. 1, an infusion pump side display (infusion pump side display unit) 3 is arranged on the surface side of the infusion pump 1 to display various information, and an infusion pump side operation including a start key 21 is performed. Part 2 is included. The user can input various information by operating the infusion pump side operation unit 2.
The infusion pump side operation unit 2 includes, in addition to the start key (start switch) 21, a power ON / OFF switch, a stop mute switch for forcibly stopping the infusion, an up / down switch as setting / input means, and the like. .
The power ON / OFF switch is used to turn on / off the main power. When the power ON / OFF switch is kept pressed for a predetermined time (approximately 2 seconds or longer), the power is turned on, and the power is turned on again for a predetermined second (approximately 3 seconds or longer). The power is controlled so as to be turned off, and care is taken so that the power cannot be turned on and off carelessly.
When the stop / mute switch is in an alarm state during infusion, a built-in buzzer sounds when pressed for a predetermined time, for example, about 2 seconds, and the infusion operation is forcibly stopped. This stop / mute switch can be muted by pressing it while the alarm is sounding, and if it is pressed for a predetermined time (about 2 seconds or more) from the state where the infusion is ready and can be started, the so-called “standby mode” Since the alarm state that forgets to start is released, for example, when waiting in the operating room with the needle to the patient completed, do not generate an alarm during the time until the infusion starts I can do it.
The infusion pump-side display (infusion pump-side display unit) 3 displays an LED display of the set injection rate (flow rate mL / h), an LED display of the scheduled injection amount (mL), and the remaining amount of the built-in battery in use. Various indications such as LED display at the step level, occlusion abnormality display that prompts treatment by blinking the letter “occlusion” when the occlusion abnormality of the liquid feeding tube 120 is detected and normal infusion cannot be performed are performed.

  FIG. 4 is a schematic view showing a state in which the door 4 of the infusion pump 1 of FIG. 1 is opened.

As shown in FIG. 4, a door 4 is formed on the surface side of the infusion pump 1 (the side on which the infusion pump-side display 3 and the like are disposed). When the door 4 is opened, a delivery tube placement groove 5 for placing the delivery tube 120 is formed on the infusion pump main body 6 side along the longitudinal direction of the infusion pump 1.
In addition, the above-mentioned finger part 30 is arrange | positioned so that contact | abutting with the liquid feeding tube 120 arrange | positioned in this liquid feeding tube arrangement | positioning groove | channel 5 is possible.

  In FIG. 4, the upper side is the infusion container 110 side of FIG. 2, and the lower side is the patient side. Therefore, the chemical | medical solution in the liquid feeding tube 120 of the "tube set 100 for infusion pumps" arrange | positioned as shown with a broken line etc. in FIG. 4 becomes a structure sent from the upper side to the lower side.

Further, as shown in FIG. 4, the upper side of the infusion pump body 6 of the infusion pump 1 (the infusion container 110 side) is an ultra-detector that detects the presence or absence of liquid such as a chemical solution in the liquid feeding tube 120 (the presence or absence of bubbles). A sound wave sensor 7 is arranged.
For this reason, when the liquid such as the chemical solution flowing from the infusion container 110 reaches the portion of the liquid feeding tube 120 where the ultrasonic sensor 7 is disposed, the presence or absence thereof can be detected.

Specifically, the ultrasonic sensor 7 is arranged to determine whether or not “bubbles” are present in the liquid such as the chemical solution from the infusion container 110 that flows into the liquid feeding tube 120.
That is, when the drug solution in the infusion container 110 is administered using the infusion pump 1, if bubbles are mixed in the drug solution, the bubbles may cause adverse effects on the patient. This is detected by the ultrasonic sensor 7, and a warning to that effect is displayed on the infusion pump side display 3 of FIG.

Further, as shown in FIG. 4, whether or not the liquid such as the chemical solution in the liquid feeding tube 120 does not flow to the upper side of the infusion pump main body 6 and below the ultrasonic sensor 7 and is in a closed state. An upstream blockage sensor 8 that detects this is disposed.
The upstream closing sensor 8 has a plunger P. FIGS. 5A, 5 </ b> B, and 5 </ b> C are schematic explanatory diagrams for explaining the operation of the plunger P. FIG.

When a chemical solution or the like normally flows in the liquid supply tube 120 of FIG. 4, the plunger P hardly moves because the chemical solution or the like flows into the liquid supply tube 120 as shown in FIG.
On the other hand, when the chemical solution or the like does not flow in the liquid feeding tube 129, that is, in the closed state, as shown in FIG. 5 (b), the plunger P moves in the direction indicated by the arrow in FIG. In the direction of pushing 120).

  Therefore, the upstream blockage sensor 8 detects the movement of the plunger P shown in FIG. 5, so that the chemical solution or the like does not flow on the upstream side of the infusion pump 1 of the liquid feeding tube 120, that is, whether or not it is blocked. It is the structure which can detect.

  As described above, when the liquid feeding tube 120 is clogged in the infusion pump 1, this indicates that the medicinal solution is not properly administered to the patient. Therefore, the infusion pump 1 is displayed on the infusion pump side display 3. Display an occlusion alarm.

In addition, since it is extremely important at which part the clogging of the liquid feeding tube 120 occurs, the infusion pump 1 is not limited to the upstream clogging sensor 8 described above, but the downstream side of the infusion pump 1 as shown in FIG. Also on the side (patient side), a downstream occlusion sensor 9 having the same configuration as the upstream occlusion sensor 8 and performing a function is disposed.
In this case, when the drug solution or the like normally flows to the patient in the solution delivery tube 120 of FIG. 4, the plunger P hardly moves because the drug solution or the like flows into the solution delivery tube 120 as shown in FIG. .
On the other hand, when the chemical solution or the like does not flow into the liquid supply tube 129, that is, in the closed state, as shown in FIG. 5C, the plunger P is pushed by the liquid supply tube 120 whose outer diameter is expanded. Move in the return direction.
Therefore, the downstream blockage sensor 9 detects the movement of the plunger P shown in FIG. 5C, so that no chemical solution or the like flows on the downstream side of the infusion pump 1 of the liquid supply tube 120, that is, the blockage is blocked. It is the structure which can detect whether it exists.

  For this reason, the infusion pump 1 can detect in which part of the liquid feeding tube 120 disposed therein the blockage occurs, and the result is displayed on the infusion pump side display 3 of FIG. It is the structure which can do.

As described above, the infusion pump 1 according to the present embodiment is configured to promptly notify the state when there is an abnormality in the flow of the chemical liquid or the like.
In addition, the infusion pump 1 has a configuration capable of accurately controlling the dose of the drug solution in the infusion container 110 shown in FIG.

By the way, if the above-mentioned abnormality detection of the infusion pump 1 and the control of the dose of the drug solution are “the tube set 100 for an infusion pump” having a standard within the range assumed by the infusion pump 1, the abnormality is appropriately abnormal. Detection can be performed.
However, when the disposable “infusion pump tube set 100” is used arbitrarily for the infusion pump 1, the standard does not match, and the infusion pump 1 may not be able to detect abnormality properly. Can be assumed.

Therefore, the infusion pump 1 stores in advance an identification symbol or the like, which is identification information of the “infusion pump tube set 100” that matches the infusion pump 1.
Therefore, when the user uses the infusion pump 1, the infusion pump side display 3 displays an identification symbol of the usable “infusion pump tube set 100” to be used. It is recommended that it be enabled only if it contains the “100” identification symbol.

However, in this case, the “infusion pump tube set 100” having an identification symbol registered in advance in the infusion pump 1 can be used, and even though it is actually usable, it cannot be used because it is not registered. Occur.
In particular, when the infusion pump 1 is used, an inexpensive “infusion pump tube set 100” originally not applicable to the infusion pump 1 may be used, and these identification symbols are not registered. There is a possibility that it cannot be used in practice.

  Therefore, in the present embodiment, the “infusion pump tube set 100” having an identification symbol or the like not registered in the infusion pump 1 is inspected, and the “infusion pump tube set 100” is used in the infusion pump 1. If it can be used, the identification symbol or the like is stored in the infusion pump 1, and the medical device inspection to be used as the “infusion pump tube set 100” can be used thereafter. It has a mode.

  Further, the infusion pump 1 shown in FIG. 1 has a computer, and the computer has a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), etc., which are not shown. Connected through.

FIG. 6 is a schematic block diagram showing a main configuration of the infusion pump 1 shown in FIG.
As shown in FIG. 6, the infusion pump 1 has an infusion pump control unit 12 that controls and judges the operation of the entire infusion pump 1. The infusion pump control unit 12 controls the above-described infusion pump-side display 3, the operation unit 2 including the start key 21, the upstream blockage sensor 8, the downstream blockage sensor 9, and the ultrasonic sensor 7, and generates time information. The infusion pump side electric motor 11 and the like that drive the device 10 and the cam shaft portion 31 and the like are also controlled. The infusion pump control unit 12 is responsible for determining and controlling the overall operation of the infusion pump 1.
Further, an external communication unit 70 is provided, and information on the infusion pump tube set 100 obtained in the medical device inspection mode can be communicated to the host computer by wire (in-hospital LAN, etc.) or wirelessly (infrared, etc.). It can be stored in a storage unit (not shown).
In addition, information about the infusion pump tube set 100 obtained by the other infusion pump 1 and stored in the storage unit of the host computer can be downloaded from the host computer to the infusion pump first information storage unit 40 described later. ing.

  In addition, the infusion pump control unit 12 also controls a storage unit that stores various data related to the infusion pump 1 and various processing units (programs). In the present embodiment, these are illustrated for convenience of explanation. The “infusion pump first information storage unit 40” and the “infusion pump second information storage unit 60” 6 will be described with reference to FIGS.

  FIG. 7 is a schematic block diagram showing the main configuration of the infusion pump first information storage unit 40 of FIG. 6, and FIG. 8 is a schematic block diagram showing the main configuration of the infusion pump second information storage unit 60 of FIG. FIG. The specific contents of FIGS. 7 and 8 will be described later.

  FIG. 9 thru | or FIG. 13 is a schematic flowchart which shows the operation example of the infusion pump 1 which concerns on this Embodiment. In the following, according to the schematic flowchart of FIG. 9 and the like, the operation and the like will be described, and the configurations of FIGS.

  First, when a user such as a medical worker intends to use the “infusion pump tube set 100” shown in FIG. 2 which is disposable once for the infusion pump 1 of FIG. For example, the identification information and the drip amount information, for example, “20 drops / 1 mL” or “60 drops / 1 mL”, which are the identification information of the “infusion pump tube set 100”, are shown in step ST of FIG. 1) and input via the operation unit 2 of the infusion pump 1 or the like.

In ST1, the input identification code of the “infusion pump tube set 100” and the drip amount information thereof are stored in the infusion pump side input information storage unit 41 of FIG.
Next, the process proceeds to ST2. In ST2, it is determined whether or not “infusion pump tube set 100” having the drip amount identification symbol input in ST1 is already stored.
That is, it is determined whether or not the “infusion pump tube set 100” has already been stored as being compatible with the infusion pump 1.

  Specifically, the determination is made with reference to “infusion pump tube set information storage unit 42” in FIG. In this “infusion pump tube set information storage unit 42”, an identification symbol of “infusion pump tube set 100” usable for the infusion pump 1 is stored in association with “infusion amount information”.

  If it is determined in ST2 that it has already been stored, the process proceeds to ST3. In ST3, a confirmation screen as to whether or not there is an intention to change (overwrite) the registration of the “infusion pump tube set 100” for the drip amount is displayed on the infusion pump side display 3 of FIG.

  Next, it is determined whether or not there is an intention to change in ST4. Specifically, the user operates the operation unit 2 in FIG. 1 and inputs instruction information as to whether or not to overwrite the registration.

  In ST4, when the instruction information for overwriting the registration is input, or the identification code of “infusion pump tube set 100” input in ST2 is not registered in “infusion pump tube set information storage unit 42” In this case, the process proceeds to medical device inspection mode ST5.

In ST5 and below, an inspection mode for determining whether or not the “infusion pump tube set 100” is compatible with the infusion pump 1 is started.
Specifically, in ST5, a message “Please attach“ the tube set for the infusion pump that you want to register ”” is displayed on the infusion pump side display 3 of FIG.

The user who sees this display attaches the “infusion pump tube set 100” to the infusion pump 1. Specifically, as shown in FIG. 4, the door 11 of the infusion pump 1 is opened, and the “liquid feeding tube 120” of the “tube set 100 for infusion pump” in FIG. Placed in.
At this time, the “infusion container 110” of the “infusion pump tube set 100” is not attached to the infusion tube 120, or the container is empty.

<Inspection mode for compatibility of liquid feeding tube for bubble detection>
Next, the door 4 in FIG. 4 is closed, and the switch of the infusion pump 1 is turned on. Then, the operation of the ultrasonic sensor 7 shown in FIG. 4 is started, and the process proceeds to ST6.

In ST6, it is determined whether or not the numerical value of the ultrasonic sensor 7 is within a predetermined threshold range.
Specifically, the “bubble presence / absence determination processing unit (program) 61” in FIG. 8 operates and refers to the “waterless ultrasonic sensor threshold information storage unit 43” in FIG. The “waterless ultrasonic sensor threshold value information storage unit 43” stores in advance a numerical range when the ultrasonic sensor 7 determines that bubbles are present.
Therefore, the “bubble presence / absence determination processing unit (program) 61” compares the numerical value of the ultrasonic sensor 7 with the information in the “waterless ultrasonic sensor threshold information storage unit 43”, and the numerical value of the ultrasonic sensor 7 is It is determined whether it is within the threshold value, that is, whether there is a bubble.

In ST6, when it is not determined that there is a bubble, when the “infusion pump tube set 100” is attached to the infusion pump 1 and a drug solution is administered to a patient, even if bubbles are generated during the administration, It is determined that the presence cannot be detected.
Therefore, it is determined that the “infusion pump tube set 100” is not compatible with the infusion pump 1, and the process proceeds to ST7.

  In ST7, the fact that the “infusion pump tube set 100” cannot be stored in the “infusion pump tube set information storage unit 42” in FIG. 7 is displayed on the infusion pump side display 3, and the process ends.

  As described above, in this embodiment, even if a serious situation such as the occurrence of bubbles occurs, it is determined that the combination with the “tube set 100 for infusion pump” that cannot detect it is inappropriate, Since the registration of the “tube set 100” is rejected, safe use of the infusion pump 1 and the “infusion pump tube set 100” can be ensured.

  On the other hand, if it is determined in ST6 that bubbles are present, the “infusion pump tube set 100” is attached to the infusion pump 1, the drug solution is administered to the patient, and bubbles are generated during the administration. It is determined that the presence can be detected appropriately, and the process proceeds to the next inspection item.

  In ST8, the message “Please connect the infusion container 110 containing the liquid in the infusion pump tube set 100” is displayed on the infusion pump side display 3.

The user who sees this display connects the “infusion container 110” containing the liquid to the “liquid feeding tube 120” in FIG. Specifically, the “hollow needle 121” is inserted into the “infusion container 110”.
Then, the liquid in the “infusion container 110” flows through the liquid feeding tube 120 and flows toward the infusion pump 1 side.
Therefore, the process proceeds to ST9. In ST9, it is determined whether or not the numerical value of the ultrasonic sensor 7 is within a predetermined threshold range.

Specifically, the “bubble presence / absence determination processing unit (program) 61” in FIG. 8 operates, and the “water-containing ultrasonic sensor threshold information storage unit 44” in FIG. 7 is referred to.
In the “water-containing ultrasonic sensor threshold value information storage unit 44”, a numerical range when the ultrasonic sensor 7 determines that there is no bubble is stored in advance.
Therefore, the “bubble presence determination processing unit (program) 61” compares the numerical value of the ultrasonic sensor 7 with the information in the “water-containing ultrasonic sensor threshold information storage unit 44”, and the numerical value of the ultrasonic sensor 7 is It is determined whether it is within the threshold value, that is, whether there is no bubble.

In ST9, when it is not determined that there is no air bubble, when the “infusion pump tube set 100” is attached to the infusion pump 1 and the drug solution is administered to the patient, there is no error even if there is no air bubble during the administration. Therefore, it is judged that there is a high possibility of detecting that there is a bubble.
Therefore, it is determined that the “infusion pump tube set 100” is not compatible with the infusion pump 1, and the process proceeds to ST10.

  In ST10, the fact that the “infusion pump tube set 100” cannot be stored in the “infusion pump tube set information storage unit 42” in FIG. 7 is displayed on the infusion pump side display 3, and the process ends.

  As described above, in this embodiment, it is determined that the combination with the “tube set 100 for infusion pump” that erroneously detects the presence of air bubbles, even though no air bubbles are generated, is not appropriate. Therefore, the safe use of the infusion pump 1 and the “infusion pump tube set 100” can be ensured.

  As described above, in this embodiment, only the combination with the “infusion pump tube set 100” that can accurately determine the presence or absence of bubbles generated in the “liquid feeding tube 120” is selected. Judgment of gender is possible.

  On the other hand, if it is determined in ST9 that there is no air bubble, the “infusion pump tube set 100” is attached to the infusion pump 1, the medicinal solution is administered to the patient, and it is erroneously determined that air bubbles are present during the administration. It is determined that there is no such thing, and the process proceeds to the next inspection item.

Next, the process proceeds to ST11. In ST11, the “infusion pump electric motor 11” is driven to rotate the cam shaft portion 31 in FIG. 3. This rotation is stored in the “cam shaft portion rotation information storage portion 45” in FIG. This is executed based on the information on the “rotation amount of the cam shaft” and the “rotation time”.
This is, for example, “the amount of rotation of the cam shaft” and “the rotation time” assuming that the flow rate of the liquid flowing in the liquid feeding tube 120 is “120 mL / h” and flows for “30 minutes”.

  The cam is operated by the rotation of the cam shaft portion 31, and the fingers 30a to 30f in FIG. That is, the fingers 30a to 30f sequentially close and release the liquid feeding tube 120 as described above (repeat this operation) to control the liquid to flow a predetermined amount per predetermined time.

  Specifically, the “camshaft rotation processing unit (program) 62 in FIG. 8 executes with reference to the“ camshaft rotation information storage unit 45 ”in FIG.

Then, the liquid sent by the infusion pump 1 flows along the liquid feeding tube 120 from the upper part to the lower part of the infusion pump 1 in FIG. 4 and is discharged from the lower side of the liquid feeding tube 120.
The discharged liquid is stored in a measuring cylinder 13 or the like shown in FIG. 14 by the user, and the amount of liquid fed is measured.
FIG. 14 is a schematic view showing the graduated cylinder 13.

<Inspection mode for compatibility of liquid feeding tube with respect to liquid feeding volume>
In ST12, a message “Please input the amount (mL) of liquid delivery” is displayed on the infusion pump side display 3.
The user who sees this message inputs the liquid feeding amount measured by the measuring cylinder 13 to the infusion pump 1.
In ST13, it is determined whether or not there is an input of the liquid supply amount (mL) supplied by the finger unit 30, and if there is an input, the process proceeds to ST14.

In ST14, the information on “Liquid delivery amount (mL)” input in ST13 is stored in the “infusion pump side liquid delivery information storage unit 46” in FIG.
Next, the process proceeds to ST15. In ST15, the “liquid amount information” in the “liquid amount information storage unit 46 on the infusion pump side”, the “rotation amount information” in the “cam portion rotation information storage unit 45”, and the “discharge amount / number of rotations” in FIG. Based on the arithmetic expression stored in the “arithmetic expression information storage unit 47”, the “discharge amount / rotation speed (mL / rot)”, which is the liquid discharge amount per camshaft rotation speed, is calculated to be 0.00001 mL / This is stored in the “discharge amount / rotation number information storage unit 48” in FIG. 7 in units of rot.

  Specifically, the “discharge amount / rotation number information calculation processing unit (program) 63” of FIG. 8 processes, but the calculation formula stored in the “discharge amount / rotation number calculation formula information storage unit 47” is For example, “discharge amount / rotation number (mL / rot) = liquid feeding amount (mL) ÷ cam shaft rotation amount (rot)”.

  Therefore, in ST15, the liquid feeding amount (mL) information can be acquired in relation to the rotation amount (rot) of the cam shaft portion 31.

  Next, the process proceeds to ST16. In ST16, the “discharge amount / rotation number information” stored in the “discharge amount / rotation number information storage unit 48” is replaced with the “discharge amount / rotation number information storage unit 49” in FIG. It is determined whether it is within the range of “number threshold information”.

This “discharge amount / rotation speed threshold information” is determined as follows, for example.
In order to reach this liquid supply amount (60 mL) when the cam shaft portion 30 is rotated by assuming that a liquid supply amount of 30 minutes at a flow rate of 120 mL / h, that is, 60 mL of liquid supply is assumed by the operation of the finger unit 30. The rotation amount of the cam shaft portion 30 is predetermined.
Then, “discharge amount / rotation speed threshold information”, which is a relationship between the predetermined liquid feeding amount and the rotation amount of the cam shaft portion 30, is stored in the “discharge amount / rotation speed threshold information storage unit 49”.

When it is determined in ST16 that “discharge amount / rotation number information” is not within the range of “discharge amount / rotation number threshold information”, the infusion pump 1 removes the liquid in the “infusion pump tube set 100”. If it is determined that the control cannot be performed with high accuracy, the process proceeds to ST17.
This determination is performed by the “discharge amount / rotation number determination processing unit (program) 64” in FIG.
In ST17, the fact that the “infusion pump tube set 100” cannot be stored in the “infusion pump tube set information storage unit 42” in FIG. 7 is displayed on the infusion pump side display 3, and the process ends.

  On the other hand, if it is determined in ST16 that “discharge amount / rotation speed information” is within the range of “discharge amount / rotation speed threshold information”, the liquid in the “infusion pump tube set 100” is used as the infusion liquid. It is determined that the pump 1 can be accurately controlled, and the process proceeds to the next inspection item and proceeds to ST18.

  In ST18, “close the specified position upstream of the infusion pump (for example, 50 cm upstream from the infusion pump 1) on the infusion pump side display 3, and press the“ start key 21 ”. Is displayed.

  The user who sees this message closes a portion 50 cm from the upper end of the infusion pump 1 of the infusion tube 120 protruding from the upper side of the infusion pump 1 of FIG. Press the “Start key 21”.

<Inspection mode for compatibility of liquid feeding tube for blockage detection>
Next, in ST19, the infusion pump 1 determines whether or not the “start key 21” has been pressed. If the “start key 21” has been pressed, the process proceeds to ST20.
In ST20, the “delivery amount (mL)” of the infusion pump 1 stored in ST14 is acquired from the “infusion pump-side infusion amount information storage unit 46”, and the cam shaft portion 31 corresponding to the flow rate of 25 mL / h is rotated. The number (rot) is calculated, and the cam shaft portion 31 is rotated for one minute.
This operation is executed by the “upstream closing cam shaft rotation processing section (program) 65” of FIG.

Next, the process proceeds to ST21. In ST21, the value of the “upstream blockage sensor 8” (see FIG. 4) when the “start key 21” pressed in ST19 is pressed is stored in the “upstream blockage information storage unit 50” in FIG. "
Next, the process proceeds to ST22. In ST22, the infusion pump 1 refers to the timing device 10 to determine whether or not a predetermined time, for example, 30 seconds has elapsed since the “start key 21” was pressed, and when 30 seconds have elapsed, ST23 Proceed to

In ST23, the value of “upstream blockage sensor 8” (that is, the movement amount of plunger P in FIG. 5B) 30 seconds after the start key 21 is pressed is stored in “30 seconds after upstream blockage information storage unit 51”. Stored as “30-second information after upstream blocking”.
Next, the process proceeds to ST24. In ST24, difference information between “upstream closing information” in “upstream closing information storage unit 50” and “30 seconds information after upstream blocking” in “upstream closing 30 second information storage unit 51” is obtained, and this difference It is determined whether the information is within the range of “upstream closing threshold information” in the “upstream closing threshold information storage unit 52” of FIG.

That is, the value of the “upstream blockage sensor 8” at the time of blockage is a value indicating the state in which liquid remains in the liquid feeding tube 120, but after 30 seconds, no liquid remains and “upstream” The value of the “occlusion sensor 8” should be a value indicating that there is no liquid (or the flow rate is reduced) in the liquid feeding tube 120.
That is, the difference information between the “upstream closing information” and the “30 seconds after upstream closing information” should be a value having a certain width, and the width information of this value becomes the “upstream closing threshold information”. .
In ST24, if the “difference information” is within the range of the “upstream closing threshold information” (the difference is large), it is determined that the “upstream closing sensor 8” has detected the blocking of the “liquid feeding tube 120”. To do.

Conversely, if the “difference information” is outside the range of the “upstream closing threshold information” and the difference is small, it is determined that the “upstream closing sensor 8” has not detected the blocking of the “liquid feeding tube 120”.
This determination is executed by the “upstream blocking value information determination processing unit (program) 66” in FIG.

If it is determined in ST24 that the “difference information” is outside the range of “upstream closing threshold information”, the process proceeds to ST25.
In ST25, the fact that the “infusion pump tube set 100” cannot be stored in the “infusion pump tube set information storage unit 42” in FIG. 7 is displayed on the infusion pump side display 3, and the process ends.

  On the other hand, if it is determined in ST24 that the “difference information” is within the range of “upstream closing threshold information”, the process proceeds to ST26.

  In ST26, “Close the specified position downstream of the infusion pump (for example, 50 cm downstream from the infusion pump 1) on the infusion pump side display 3, and press the“ start key 21 ”. Is displayed.

  The user who sees this message closes a portion 50 cm from the lower end of the infusion pump 1 of the infusion tube 120 protruding from the lower side of the infusion pump 1 of FIG. Press the “start key 21”.

Next, in ST27, the infusion pump 1 determines whether or not the “start key 21” has been pressed. If the “start key 21” has been pressed, the process proceeds to ST28.
In ST28, the “delivery amount (mL)” of the infusion pump 1 stored in ST14 is acquired from the “infusion pump-side infusion amount information storage unit 46”, and the cam shaft portion 31 corresponding to the flow rate of 25 mL / h is rotated. The number (rot) is calculated, and the cam shaft portion 31 is rotated for 2 minutes.
This operation is executed by the “downstream closing cam shaft rotation processing section (program) 67” in FIG.

Next, the process proceeds to ST29. In ST29, the value of the “downstream blocking sensor 9” (see FIG. 4) when the “start key 21” pressed in ST27 is pressed (that is, the amount of movement of the plunger P in FIG. 5C) is shown in FIG. Is stored as “downstream blocking information” in the “downstream blocking information storage unit 53”.
Next, the process proceeds to ST30. In ST30, the infusion pump 1 refers to the timing device 10 to determine whether or not 30 seconds have elapsed since the “start key 21” was pressed, and when 30 seconds have elapsed, the process proceeds to ST31.

  In ST31, the value of “downstream blocking sensor 9” 30 seconds after the start key 21 is pressed is stored as “30 seconds information after downstream blocking” in the “30 seconds information storage section 54 after downstream blocking”.

  Next, the process proceeds to ST32. In ST32, difference information between “downstream blocking information storage unit 53” “downstream blocking information” and “downstream blocking 30 seconds information storage unit 54” “downstream blocking 30 seconds information” is obtained, and this difference is calculated. It is determined whether the information is within the range of “downstream closing threshold information” in the “downstream closing threshold information storage unit 55” of FIG.

That is, the value of the “downstream blockage sensor 9” at the time of blockage is a value indicating the state in which the liquid remains in the liquid feeding tube 120, but after 30 seconds, the liquid further increases and the “downstream blockage sensor 9” The value of “sensor 9” should be larger.
That is, the difference information between the “downstream blocking information” and the “30 seconds after downstream blocking information” should be a value having a certain width or more, and the width information of this value is “upstream closing threshold information”. Become.

In ST32, if the “difference information” is within the range of the “downstream closing threshold information” (the difference is large), it is determined that the “upstream closing sensor 9” has detected the blocking of the “liquid feeding tube 120”.
Conversely, if the “difference information” is outside the range of the “upstream closing threshold information” and the difference is small, it is determined that the “downstream blocking sensor 9” has not detected the blocking of the “liquid feeding tube 120”.
This determination is performed by the “downstream blocking value information determination processing unit (program) 68” in FIG.

If it is determined in ST32 that the “difference information” is outside the range of “downstream closing threshold information”, the process proceeds to ST33.
In ST33, the fact that the “infusion pump tube set 100” cannot be stored in the “infusion pump tube set information storage unit 42” in FIG. 7 is displayed on the infusion pump side display 3, and the process ends.

  Thus, in the present embodiment, the “upstream blockage sensor 8” and the “downstream blockage sensor 9” of the infusion pump 1 function normally with respect to the “infusion pump tube set 100” and detect the blockage. It is the structure which test | inspects beforehand whether or not.

On the other hand, if it is determined in ST32 that the above-described “difference information” is within the range of “upstream closing threshold information”, the process proceeds to ST33.
In ST32, the process of inspecting the compatibility between the infusion pump 1 and the “infusion pump tube set 100” is completed once.

That is, in ST34, “1” is added to the “infusion pump-side measurement count storage unit 56” in FIG. Specifically, the “infusion pump-side measurement frequency determination processing unit (program) 69 of FIG. 8 executes.
In the present embodiment, the above-described bubble detection inspection (ST6 to ST10), discharge amount inspection (ST11 to ST17), and blockage detection inspection (ST18 to STST33), which are particularly important when using the infusion pump 1, are performed. Thus, the safety is ensured.

  In the present embodiment, the above-described inspections (ST6 to ST33) are performed three times in total using the “tube set 100 for infusion pumps” having the same identification symbol, and “registration is not possible” in all three times. It is determined whether or not in ST35. In addition, using the “tube set 100 for infusion pumps” with the same identification symbol, for the amount of fluid to be pumped and blockage detection, an additional test is performed once, and the average value of the previous three measurement results is within ± 30. Inspected for no.

  If it is determined in ST35 that three inspections and one additional inspection have been performed, the process proceeds to ST36. In ST 36, the “infusion pump tube set information storage unit 42” is obtained by associating the identification symbol of the “infusion pump tube set 100” having the identification symbol with average value information such as drip amount information and discharge amount / rotation number information. Is remembered.

  Next, in ST37, it is displayed on the infusion pump side display 3 that the registration of the “infusion pump tube set 100” has been completed.

As a result of this registration, the identification symbol of the “infusion pump tube set 100” is newly registered in the infusion pump 1, and thereafter, the “infusion pump tube set 100” is adapted to the infusion pump 1. .
Therefore, after that, the user can use the “infusion pump tube set 100” in the infusion pump 1 with confidence.

On the other hand, since the user can quickly grasp the fact of the “infusion pump tube set 100” that does not conform, it is safe to continue using the non-conforming “infusion pump tube set 100”. Sex is secured.
In addition, as described above, this compatibility inspection is performed with items that are particularly important for safety (bubble detection inspection (ST6 to ST10), liquid supply amount inspection (ST11 to ST17), blockage detection inspection (ST18 to STST33). )), The result is an extremely reliable test.

Further, when the inexpensive “infusion pump tube set 100” to be attached is used in the infusion pump 1, the “infusion pump tube set 100” to be attached is stored in the “infusion pump tube set information storage”. In many cases, it is not registered in the “part 42”, and its use is often hesitant.
However, in this embodiment, even if it is such an unregistered “tube set for infusion pump 100”, it is determined whether or not it can be used later by simply and accurately inspecting, and the result is obtained. Since it is registered, the infusion pump 1 is easy to use for the user.

(Second Embodiment)
FIG. 15 is a schematic diagram showing an external appearance of, for example, a syringe pump 200 that is a medical device provided with a medical device inspection apparatus, and FIG. 16 is a single-use disposable (disposal) attached to the syringe pump 200 of FIG. It is the schematic which shows the syringe 300 which is a medical device which is.

As shown in FIG. 16, the syringe 300 includes, for example, a syringe body 310 that stores a drug solution, and includes a pusher 320 for feeding the drug solution in the syringe body 310 to a patient.
The syringe body 310 has a distal end opening 311 at the distal end thereof, and a flange 312 is formed on the proximal end side (the opposite side of the distal end opening 311).
Then, by moving the pusher 320 in FIG. 16 so as to be pushed into the syringe main body 310, the tip opening 311 is discharged from the liquid such as the chemical liquid stored in the syringe main body 310.

A syringe pump 200 shown in FIG. 15 has a syringe pump side display 201 for displaying various types of information, and also has a syringe pump side input device 202 for inputting various types of instruction information and the like.
In addition to the start key (start switch), the syringe pump side input device 202 includes a power ON / OFF switch, a stop mute switch for forcibly stopping the infusion, a jog dial that is a setting, a confirmation switch, and the like.
The power ON / OFF switch is used to turn on / off the main power. When the power ON / OFF switch is kept pressed for a predetermined time (approximately 2 seconds or longer), the power is turned on, and the power is turned on again for a predetermined second (approximately 3 seconds or longer). The power is controlled so as to be turned off, and care is taken so that the power cannot be turned on and off carelessly.
When the stop / mute switch is in an alarm state during infusion, a built-in buzzer sounds when pressed for a predetermined time, for example, about 2 seconds, and the infusion operation is forcibly stopped. This stop / mute switch can be muted by pressing it while the alarm is sounding, and if it is pressed for a predetermined time (about 2 seconds or more) from the state where the infusion is ready and can be started, the so-called “standby mode” Since the alarm state that forgets to start is released, for example, when waiting in the operating room with the needle to the patient completed, do not generate an alarm during the time until the infusion starts I can do it.
The infusion pump-side display (infusion pump-side display unit) 3 displays an LED display of the set injection rate (flow rate mL / h), an LED display of the scheduled injection amount (mL), and the remaining amount of the built-in battery in use. Various indications such as LED display at the step level, occlusion abnormality display that prompts treatment by blinking the letter “occlusion” when the occlusion abnormality of the liquid feeding tube 120 is detected and normal infusion cannot be performed are performed.
Moreover, as shown in FIG. 15, the syringe pump 200 has a configuration in which the syringe 300 shown in FIG. 16 can be attached.

Specifically, a slit 203 that can receive the flange 312 of the syringe 300 is formed in a portion where the syringe 300 of the syringe pump 200 is disposed.
For this reason, the syringe 300 shown in FIG. 16 is arranged so that the flange 312 is inserted into the slit 203 of the syringe pump 200, whereby the syringe 300 can be positioned with respect to the syringe pump 200.

The syringe pump 200 has a slider 204 that can move in the direction of arrow X in FIG. Then, as shown in FIG. 15, the slider 204 can be moved into the syringe main body 310 by the slider 204 by arranging the slider 204 so as to contact the pusher 320 of the syringe 300.
That is, the syringe pump 200 is configured to be able to control the movement of the pusher 320 by moving the slider 204.

Therefore, a user such as a medical worker puts the chemical solution in the syringe body 310, and the syringe 300 together with the pusher 320 is arranged in the syringe pump 200 in FIG. 15, and the liquid supply tube 330 (see FIG. 15), and arrange | position so that the liquid delivery tube 330 may be connected with a patient side, and by controlling the movement of the slider 204 of the syringe pump 200 in this state, a desired quantity of chemical | medical solution is made at a desired speed. It can be administered to a patient.
That is, the syringe pump 200 is configured such that a chemical solution stored in the syringe 300 can be accurately administered to a patient or the like using the disposable syringe 300 every time.

By the way, if the syringe 300 which has the specification in the range which the syringe pump 200 assumes control of the dosage of the chemical | medical solution of the syringe pump 200, abnormality detection etc. can be performed appropriately.
However, when the disposable syringe 300 for each use is arbitrarily used for the syringe pump 200, it may be assumed that the standard is not met and the syringe pump 300 cannot properly feed liquid.

Therefore, an identification symbol or the like that is identification information of the syringe 300 that matches the syringe pump 200 is stored in the syringe pump 200 in advance.
Therefore, when the user uses the syringe pump 200, when the syringe pump-side display 201 displays the identification symbol of the syringe 300 that can be used, and the identification symbol of the syringe 300 to be used is included. It is recommended that it be usable as long as possible.

However, in this case, a syringe 300 having an identification symbol registered in advance in the syringe pump 200 can be used, and there is a problem that even though it can actually be used, it cannot be used because it is not registered.
In particular, an inexpensive syringe 300 is used for the syringe pump 200, but these identification symbols and the like are often not registered and may not be used in practice.

  Therefore, in the present embodiment, the syringe 300 having an identification symbol or the like that is not registered in the syringe pump 200 is inspected, and whether or not the syringe 300 is compatible with the syringe pump 200 is matched. In such a case, the identification symbol or the like is stored in the syringe pump 200, and thereafter, the syringe 300 is intended to be usable.

  Further, the syringe pump 200 shown in FIG. 15 has a computer, which includes a CPU (Central Processing Unit), a RAM (Random Access Memory), a ROM (Read Only Memory), etc., which are not shown. Connected through.

FIG. 17 is a schematic block diagram showing the main configuration of the syringe pump 200 shown in FIG.
As shown in FIG. 17, the syringe pump 200 has a syringe pump control unit 205 that controls and judges the operation of the entire syringe pump 200.
The syringe pump control unit 205 controls the syringe pump side display 201 and the syringe pump side input device 202 described above, and measures the outer diameter of the syringe 300 in FIG. 16 and the slider 204 in FIG. 15 is controlled by a slider moving motor 207 that moves the slider in the arrow X direction and a pusher moving amount measuring device 208 that measures the distance moved by the slider 204 of the pusher 320 of the syringe 300 in FIG. The syringe pump control unit 205 governs determination and control of the overall operation of the syringe pump 200.
In addition, an external communication unit 214 is provided, and information on the syringe 300 obtained in the medical device examination mode can be communicated to the host computer by wire (in-hospital LAN, etc.) or wirelessly (infrared, etc.). It can be stored in the figure.
Moreover, the information of the syringe 300 obtained by the other syringe pump 200 and stored in the storage unit of the host computer can be downloaded from the host computer to the syringe pump various information storage unit 220 described later.

  The syringe pump control unit 205 also controls a pressure sensor 209 that measures the pressure in the syringe body 310 when the pusher 320 is inserted into the syringe body 310. With this pressure sensor 209, the closing pressure in the syringe body 310 when the pusher 320 is inserted can be measured, and information on the sliding resistance of the pusher 320 can be acquired from this closing pressure.

In addition, the syringe pump control unit 205 also controls a syringe pump various information storage unit 220 that stores various data related to the syringe pump 200 and various processing units (programs), which will be described later.
FIG. 18 is a schematic block diagram showing a main configuration of the syringe pump various information storage unit 220 of FIG.

  FIG. 19 thru | or FIG. 21 is a schematic flowchart which shows the operation example of the syringe pump 200 which concerns on this Embodiment. In the following, according to the schematic flowchart of FIG. 19 and the like, the operation and the like will be described, and the configurations of FIGS.

  First, when a user such as a medical worker intends to use the syringe 300 shown in FIG. 16 that is disposable once for the syringe pump 200 shown in FIG. 15, first, the syringe 300 to be used is identified. Information, for example, an identification symbol and its size information, for example, “2.5 mL, 5 mL, 10 mL, 20 mL, 30 mL, 50 mL” are input via the syringe pump side input device 202 of the syringe pump 200 in ST100 of FIG. To do.

In ST100, the input identification symbol of the syringe 300 and its size information are stored in the “syringe pump side input information storage unit 221” of FIG.
Next, the process proceeds to ST101. In ST101, it is determined whether or not the syringe 300 having the identification symbol of the size input in ST100 is already stored.
That is, it is determined whether or not the syringe 300 is already stored as being compatible with the syringe pump 200.

  Specifically, the determination is made with reference to the “syringe information storage unit 222” in FIG. In the “syringe information storage unit 222”, identification symbol information of the syringe 300 that can be used for the syringe pump 200 is stored in association with the “size information”.

  If it is determined in ST101 that it has already been stored, the process proceeds to ST102. In ST102, a confirmation screen as to whether or not there is an intention to change (overwrite) the registration of the syringe 300 of the size is displayed on the syringe pump side display 201 of FIG.

  Next, in ST103, it is determined whether or not there is an intention to change. Specifically, the user operates the syringe pump side input device 202 of FIG. 15 and inputs instruction information as to whether or not to overwrite the registration.

In ST103, when the instruction information for overwriting the registration is input, or when the identification symbol of the syringe 300 input in ST101 is not registered in the “syringe information storage unit 222”, the process proceeds to the medical device inspection mode ST104. .
In ST104 and the subsequent steps, an inspection process for determining whether or not the syringe 300 is compatible with the syringe pump 200 is started.

  Specifically, in ST104, the message “Please attach the“ syringe ”that you want to register” is displayed on the syringe pump side display 201 of FIG.

A user who sees this display attaches the syringe 300 to the syringe pump 200. Specifically, as shown in FIG. 15, the syringe 300 is placed on the syringe pump 200 so that the flange 312 of the syringe body 310 of the syringe 300 of FIG. 16 is inserted into the slit 203 of the syringe pump 300, and thereafter As shown in FIG. 15, the slider 204 of the syringe pump 200 is brought into contact with the pusher 320 of the syringe 300.
At this time, a liquid corresponding to the size (2.5 mL, etc.) of the syringe 300 is accommodated in the syringe body 310 of the syringe 300.

  Next, the process proceeds to ST104. In ST104, the switch of the syringe pump 200 is turned on, the outer diameter of the “syringe 300” attached to the syringe pump 200 is measured by the syringe outer diameter measuring device 206 in FIG. 7, and “syringe outer diameter information storage” in FIG. Part 223 ".

  Next, the process proceeds to ST106. In ST106, the "slider moving motor 207" is driven based on "motor rotating speed information" and "driving time information" in the "slider moving motor rotation speed and driving time information storage unit 224" in FIG.

Here, in the “slider moving motor rotation speed and driving time information storage unit 224”, for example, “motor rotation speed information” and “driving time information” that differ depending on the size of the syringe 300 are set in advance.
For example, when the size of the syringe 300 is “2.5 mL”, “motor rotation speed information” that stores a flow rate of “4 mL / h” is stored and the “drive time” is “30 minutes”. It is remembered that

  Therefore, the slider moving motor 207 is driven based on such information, and by this driving, the slider 204 in FIG. 15 moves toward the syringe body 310, and the movement of the slider 204 causes the pusher 320 of the syringe 300 to move. And move in the direction of insertion into the syringe body 310.

That is, the pusher 320 moves so that the liquid in the syringe main body 310 of FIG.
The operation of the slider drive motor 207 is executed by the “slider movement motor drive processing unit (program) 210” in FIG.

<Syringe compatibility inspection mode for sliding resistance (blockage detection)>
The movement of the pusher 320 increases the pressure (blocking pressure) in the syringe body 310, and a sliding resistance is applied to the pusher 320.
Therefore, in the present embodiment, the pressure sensor 209 measures the occlusion pressure and acquires the sliding resistance value.
The operation of obtaining the sliding resistance value from the occlusion pressure of the pressure sensor 209 is executed by the “sliding resistance determination processing unit (program) 211” in FIG.

It is determined whether or not the obtained sliding resistance value is within the range of “sliding resistance value threshold information” in “sliding resistance value threshold information storage unit 225” in FIG.
That is, the “sliding resistance value” is a resistance value applied to the pusher 320 that moves in the syringe body 310. If the sliding resistance value is high, the pusher 320 is difficult to move, that is, the syringe 300 is in a closed state. It turns out that it is.

Therefore, in the present embodiment, as “sliding resistance value threshold information”, a range of sliding resistance values that are not closed is stored in advance as “sliding resistance value threshold information”.
Therefore, in ST107, by comparing the “sliding resistance value” when the pusher 320 is moved by the slider 204 with “sliding resistance value threshold information”, it is determined whether or not the syringe 300 is in the closed state. Can do.

If it is determined in ST107 that the sliding resistance value information is not within the range of “sliding resistance threshold information”, that is, it is determined to be in the closed state, the process proceeds to ST108.
In ST108, the fact that the syringe 300 cannot be stored in the “syringe information storage unit 222” in FIG. 18 is displayed on the syringe pump side display 201, and the process ends.

  Thus, in this Embodiment, the syringe 300 which a blockage state generate | occur | produces becomes a structure which makes it unusable by refusing registration, and ensures safe use.

On the other hand, if the sliding resistance value information is within the range of “sliding resistance threshold value information” in ST107, it is determined that a closed state does not occur, and the process proceeds to ST109.
In ST109, “sliding resistance value information” is stored in “sliding resistance value information storage unit 226” in FIG.

<Syringe compatibility inspection mode for liquid delivery amount>
As described above, when the pusher 320 is pushed into the syringe body 310 in a state where the liquid is contained in the syringe body 310, the liquid is discharged from the distal end opening 311 of the syringe 300 to the outside through the liquid feeding tube 330. Discharged.
Here, the user accumulates the discharged liquid in a graduated cylinder 13 or the like shown in FIG. 14 and measures the liquid feeding amount.

In ST110, a message “Please input the amount (mL) of liquid delivery” is displayed on the syringe pump side display 201.
The user who sees this message inputs the liquid feeding amount measured by the graduated cylinder 13 into the syringe pump 20.

  In ST111, it is determined whether or not a liquid feeding amount (mL) has been input. If there is an input, the process proceeds to ST112.

  In ST112, the information of “Liquid delivery amount (mL)” input in ST111 is stored in “Syringe side liquid delivery amount information storage unit 227” in FIG.

  Next, the process proceeds to ST113. In ST113, "Syringe motor rotation speed and drive time information storage unit 224" "Motor rotation speed" in FIG. 18 and "Syringe side liquid supply amount information storage unit 227" "Liquid supply amount information" to "Syringe" “Cross-sectional area information” is calculated and stored in the “syringe cross-sectional area information storage unit 228”.

Specifically, “motor movement amount (mm) = motor movement amount (mm) × motor rotation speed (rot)”, “syringe cross-sectional area (mm ² ) = liquid feeding amount (mL) ÷ motor Since “moving amount (mm)”, since the discharge amount of the syringe (the amount of liquid (mL) corresponding to the moving amount of the motor (mm) is known from the “syringe cross-sectional area (mm ² )”, in this embodiment, the discharge amount Whether or not the amount is appropriate is determined based on the “syringe cross-sectional area”.

  Note that the operation of ST113 is executed by the “syringe cross-sectional area information generation processing unit (program) 212 in FIG.

Next, in ST114, it is determined whether the syringe cross-sectional area information is within the range of the syringe cross-sectional area threshold information.
That is, the “syringe cross-sectional area threshold information storage unit 229” of FIG. 18 stores threshold information of “syringe cross-sectional area” corresponding to an appropriate discharge amount of the syringe 300.
Therefore, in ST114, it is determined whether or not the liquid discharge amount of the syringe 300 is appropriate by determining whether or not the “syringe sectional area information” calculated in ST113 is within the range of the “syringe sectional area threshold information”. Will do.

  In ST114, when the “syringe cross-sectional area information” is not within the range of the “syringe cross-sectional area threshold information”, it is determined that even if the syringe 300 is attached to the syringe pump 200, the discharge amount of the chemical cannot be accurately controlled. The process proceeds to ST115.

  In ST115, the fact that the syringe 300 cannot be stored in the “syringe information storage unit 222” of FIG. 18 is displayed on the syringe pump side display 201, and the process ends.

  On the other hand, when it is determined in ST114 that “syringe cross-sectional area information” is within the range of “syringe cross-sectional area threshold information”, it is determined that the liquid in the syringe 300 can be accurately controlled by the syringe pump 200. , Go to ST116.

  In ST116, “Please set the syringe scale to“ 0 ”and set the syringe again” is displayed on the syringe pump side display 201.

  The user who sees this display once removes the syringe 300 of FIG. 15 from the syringe pump 200, returns the pusher 320 to the original position, sets the scale to “0”, and attaches the syringe 300 to the syringe pump 200 again. To do.

In ST117, the syringe pump 200 determines whether or not the syringe 300 is attached. If it is determined that the syringe 300 is attached, the process proceeds to ST118.
In ST118, the “slider moving motor 207” causes the “pushing element 320” to move to the “syringe body 310” in the insertion direction and to the push-off position. Then, the push-off position information is measured by the “push-button movement amount measuring device 208” in FIG. 17 and stored in the “push-button push-off position information storage unit 230”.

In ST118, the process of checking the compatibility between the syringe pump 200 and the syringe 300 is completed once.
That is, in ST119, “1” is added to the “syringe pump side measurement count storage unit 231” in FIG. Specifically, the “syringe pump side measurement number determination processing unit (program) 213 of FIG. 17 executes.

  As described above, in the present embodiment, the above-described occlusion detection (sliding resistance value) (ST106 to ST109) and discharge amount inspection (syringe cross-sectional area) (ST110 to ST115) are particularly important when using the syringe pump 200. ) To ensure its safety.

  Also, in the present embodiment, the above-described inspections (ST105 to ST118) are performed a predetermined number of times, for example, three times using different syringes 300 having the same identification symbol, and whether or not “registration is not possible” has been made all three times. Is determined in ST120. Furthermore, using a different “syringe 300” with the same identification symbol, the sliding resistance (clogging detection) and the amount of liquid to be fed are further checked once, within the average value of ± 30 of the previous three measurement results. Is inspected.

  If it is determined in ST120 that three inspections and one additional inspection have been performed, the process proceeds to ST121. In ST121, the identification symbol of the syringe 300 having the identification symbol is stored in the “syringe information storage unit 222” in association with average value information such as “drip amount information and discharge amount / rotation number information”.

  Next, in ST122, it is displayed on the syringe pump side display 201 that the registration of the syringe 300 is completed.

By this registration, the identification symbol of the syringe 300 is newly registered in the infusion pump 1, and thereafter, the syringe 300 is adapted to the syringe pump 200.
Therefore, after that, the user can use the syringe 200 with confidence in the infusion pump 1.

On the other hand, since the user can quickly grasp the fact of the syringe 300 that has not been adapted, safety is ensured without continuing to use the non-conforming syringe 300.
In addition, as described above, this compatibility inspection includes items that are particularly important for safety (blockage detection (sliding resistance value) (ST106 to ST109)), liquid feeding amount inspection (syringe cross-sectional area) (ST110 to ST110). Since the test is conducted for ST115)), the reliability of the result is an extremely high inspection.

Further, when the syringe pump 200 is used in a foreign country, the “syringe 300” to be mounted is often unregistered in the “syringe information storage unit 222” in FIG. 18, and its use is often discouraged. .
However, in this embodiment, even if it is such an unregistered “syringe 300”, it is determined whether it can be used afterwards by simply and accurately inspecting, and the result is registered. The syringe pump 200 is easy to use for the user.
