The pusher fixing portion 13 can fix the pusher flange 56 to the slider 12 by sandwiching the pusher flange 56 of the mounted syringe 50. When the pusher flange 56 is fixed to the slider 12 by the pusher fixing portion 13, the pusher 55 moves integrally with the slider 12 as the slider 12 moves in the extending direction A. At this time, the outer cylinder 51 mounted on the mounting portion 11 is fixed to the medical pump 1 in the extending direction A because a part of the outer cylinder flange 53 is housed in the slit 15. .. Therefore, when the slider 12 moves to the tip side of the syringe 50, the pusher 55 moves to the tip side with respect to the outer cylinder 51, and the liquid contained in the hollow portion 52 is discharged from the outlet hole 54. Therefore, the liquid contained in the hollow portion 52 can be sent to the inside of the living body through the tube 60.

As shown in FIGS. 1 and 2, the medical pump 1 includes a syringe clamp 14 that fixes an outer cylinder 51 of the syringe 50 mounted on the mounting portion 11. In the present embodiment, the syringe clamp 14 is movable along the direction B orthogonal to the extending direction A, and the outer cylinder 51 of the syringe 50 mounted on the mounting unit 11 is replaced with the mounting unit 11. It is possible to fix it by sandwiching it between them. Further, fixing the outer cylinder 51 with the syringe clamp 14 makes it difficult for a part of the outer cylinder flange 53 to come off the slit 15, so that the outer cylinder 51 is firmly fixed to the medical pump 1.

As shown in FIGS. 1 and 2, the medical pump 1 includes a notched tube guide portion 16 at a position closer to the tip side than the syringe 50 when the syringe 50 is placed on the placing portion 11. I have it. The tube guide portion 16 is used for allowing the tube 60 attached to the tip of the syringe 50 to pass therethrough while positioning the syringe 50 placed on the placing portion 11.

The external power acquisition unit 40 acquires AC power from an external power source such as a commercial power grid. The external power acquisition unit 40 may acquire the AC power from a plug inserted into an outlet via a cable, for example. The external power acquisition unit 40 includes an AC/DC converter 41. The AC/DC converter 41 converts AC power acquired from an external power source into DC power. The external power acquisition unit 40 can supply the DC power output from the AC/DC converter 41 to each component including the alarm notification unit 33 of the medical pump 1. The medical pump 1 can operate with the power supplied from the external power acquisition unit 40 when the external power acquisition unit 40 is acquiring AC power from the external power source.

The external power acquisition unit 40 can charge the main battery 42 and the sub battery 43.

The main battery 42 is a battery capable of supplying electric power to each component of the medical pump 1. The main battery 42 can independently supply power to each component of the medical pump 1 in a state where the main battery 42 is not supplied with power from the external power acquisition unit 40.

The main battery 42 is a medical pump instead of the external power acquisition unit 40 when the external power acquisition unit 40 is not acquiring power from the external power source, for example, when the plug is not inserted into the outlet. Electric power can be supplied to each component including one alarm notification unit 33.

The main battery 42 may be a rechargeable secondary battery. The main battery 42 may be, for example, a lithium ion battery or a nickel hydrogen battery, but is not limited to these, and may be another secondary battery.

The main battery 42 can charge the sub battery 43.

The sub-battery 43 can supply power to at least the alarm notification unit 33 of the medical pump 1. The sub-battery 43 can independently supply power to the alarm notification unit 33 while it is not supplied with power from the external power acquisition unit 40 and the main battery 42. The sub-battery 43 may be set so that it can supply power only to the alarm notification unit 33 of the medical pump 1.

When both the external power acquisition unit 40 and the main battery 42 cannot supply power to the medical pump 1, the sub-battery 43 supplies power to the alarm notification unit 33 and issues an alarm to the alarm notification unit 33. It is possible to be notified. The sub-battery 43 supplies power to the alarm notification unit 33 for at least a first predetermined time when both the external power acquisition unit 40 and the main battery 42 cannot supply power to the medical pump 1. It is possible. The first predetermined time is, for example, 3 minutes.

The sub-battery 43 may be a capacitor. The sub-battery 43 may be, for example, an electric double layer capacitor (super capacitor), a lithium ion capacitor, an aluminum electrolytic capacitor, a ceramic capacitor, or the like, but is not limited to these, and may be another capacitor. When the sub-battery 43 is an electric double layer capacitor, the sub-battery 43 can be small and have a large capacity as compared with the case of being another capacitor.

The charging of the main battery 42 and the sub-battery 43 will be described with reference to FIGS. 4 and 5. FIG. 4 is a diagram showing a state of charging when the external power acquisition unit 40 is acquiring power from the external power source. FIG. 5: is a figure which shows the mode of charge when the external electric power acquisition part 40 has not acquired electric power from the external electric power source.

As shown in FIGS. 4 and 5, the external power acquisition unit 40 is connected to both the main battery 42 and the sub battery 43. Further, the main battery 42 is connected to the sub battery 43.

As shown in FIG. 4, when the external power acquisition unit 40 is acquiring power from the external power source, the external power acquisition unit 40 can charge the main battery 42 via the charging path P1. Further, when the external power acquisition unit 40 is acquiring power from the external power source, the external power acquisition unit 40 can charge the sub-battery 43 through the charging path P2.

As shown in FIG. 5, when the external power acquisition unit 40 is not acquiring power from the external power source, the main battery 42 can charge the sub battery 43 through the charging path P3.

In this way, when the external power acquisition unit 40 is not acquiring power from the external power source, the main battery 42 can charge the sub-battery 43 so that the main battery 42 can be used independently for medical use. It is possible to prevent the charge amount of the sub-battery 43 from decreasing due to self-discharge while the pump 1 is operating.

Further, since the main battery 42 can charge the sub-battery 43 when the external power acquisition unit 40 is not acquiring power from the external power source, the sub-battery 43 can be self-discharged like a capacitor. It is possible to adopt a large device. For example, if a nickel-hydrogen battery with a small self-discharge is adopted as the sub-battery 43, the nickel-hydrogen battery needs to be replaced regularly every two to three years. However, if a capacitor is used as the sub-battery 43, it is not necessary to replace it regularly. Therefore, if a capacitor is used as the sub-battery 43, the sub-battery 43 can be mounted on the substrate inside the medical pump 1. Further, since the capacitor is cheaper than the nickel-hydrogen battery, if the capacitor is used as the sub-battery 43, the cost of the medical pump 1 can be reduced.

With reference to FIG. 3 again, the external power monitoring unit 70, the main battery monitoring unit 72, and the sub battery monitoring unit 73 will be described.

The external power monitoring unit 70 monitors whether or not the external power acquisition unit 40 can supply power to the medical pump 1. The external power monitoring unit 70 transmits to the control unit 23 a signal indicating whether or not the external power acquisition unit 40 can supply power to the medical pump 1.

The external power monitoring unit 70 detects the voltage on the output side of the AC/DC converter 41, for example, and when a predetermined voltage is detected, the external power acquisition unit 40 can supply power to the medical pump 1. If the predetermined voltage is not detected, it is determined that the external power acquisition unit 40 is not in a state in which power can be supplied to the medical pump 1. Alternatively, the external power monitoring unit 70 detects, for example, the voltage on the input side of the AC/DC converter 41 and determines whether the external power acquisition unit 40 is in a state in which power can be supplied to the medical pump 1. You may.

For example, when the external power acquisition unit 40 does not acquire power from the external power source, the voltage on the input side and the output side of the AC/DC converter 41 is not a predetermined voltage, so the external power monitoring unit 70 sets the external power The acquisition unit 40 determines that power cannot be supplied to the medical pump 1.

The main battery monitoring unit 72 monitors whether or not the main battery 42 can supply electric power to the medical pump 1. The main battery monitoring unit 72 sends to the control unit 23 a signal indicating whether or not the main battery 42 is in a state capable of supplying electric power to the medical pump 1.

For example, the main battery monitoring unit 72 detects the charge amount of the main battery 42, and when the charge amount is equal to or more than a predetermined threshold value, determines that the main battery 42 is in a state capable of supplying electric power to the medical pump 1. Then, when the charge amount is less than the predetermined threshold value, it is determined that the main battery 42 is not in a state capable of supplying electric power to the medical pump 1. Alternatively, the main battery monitoring unit 72 detects the output voltage of the main battery 42, and the main battery 42 supplies electric power to the medical pump 1 based on whether the output voltage is equal to or higher than a predetermined threshold value. You may judge whether it is a possible state.

The sub-battery monitoring unit 73 monitors whether or not the sub-battery 43 can supply power to the alarm notification unit 33 of the medical pump 1. The sub-battery monitoring unit 73 transmits to the control unit 23 a signal indicating whether or not the sub-battery 43 can supply power to the alarm notification unit 33.

For example, the sub-battery monitoring unit 73 detects the charge amount of the sub-battery 43, and when the charge amount is equal to or more than a predetermined threshold value, determines that the sub-battery 43 is in a state in which power can be supplied to the alarm notification unit 33. Then, if the charge amount is less than the predetermined threshold value, it is determined that the sub-battery 43 is not in a state in which power can be supplied to the alarm notification unit 33. The sub-battery monitoring unit 73 may determine the charge amount of the sub-battery 43 based on the output voltage of the sub-battery 43, for example.

The control unit 23 receives from the external power monitoring unit 70 a signal indicating whether or not the external power acquisition unit 40 is in a state capable of supplying power to the medical pump 1. The control unit 23 receives from the main battery monitoring unit 72 a signal indicating whether or not the main battery 42 is in a state capable of supplying electric power to the medical pump 1. The control unit 23 receives from the sub-battery monitoring unit 73 a signal indicating whether or not the sub-battery 43 is in a state in which power can be supplied to the alarm notification unit 33.

When the control unit 23 receives a signal indicating that power cannot be supplied from any two of the external power monitoring unit 70, the main battery monitoring unit 72, and the sub-battery monitoring unit 73, the control unit 23 waits for the first predetermined time. In the meantime, the alarm notification unit 33 is caused to notify the alarm. For example, when the control unit 23 receives a signal indicating that the power cannot be supplied from the external power monitoring unit 70 and the main battery monitoring unit 72, the control unit 23 issues an alarm to the alarm notification unit 33 based on the power supplied by the sub battery 43. Let me know. Further, for example, when the control unit 23 receives a signal indicating that the power cannot be supplied from the external power monitoring unit 70 and the sub-battery monitoring unit 73, the alarm notification unit 33 is based on the power supplied by the main battery 42. To alert you. In addition, for example, when the control unit 23 receives a signal indicating that power cannot be supplied from the main battery monitoring unit 72 and the sub battery monitoring unit 73, based on the power supplied by the external power acquisition unit 40, the control unit 23 issues an alarm notification. The unit 33 is informed of the alarm. In these cases, the control unit 23 may stop the operation of the pump driving unit 34 and the like to stop the function of the medical pump 1 as a pump.

Thus, when any two of the external power acquisition unit 40, the main battery 42, and the sub battery 43 cannot supply power, the control unit 23 causes the external power acquisition unit 40, the main battery 42, and the sub battery By causing the alarm notification unit 33 to issue an alarm based on the remaining one of the batteries 43 that can supply electric power, the alarm is not issued even though the medical pump 1 cannot operate. Can be prevented.

The control unit 23 is in a state in which any two of the external power acquisition unit 40, the main battery 42, and the sub-battery 43 cannot supply power during the second predetermined time after the medical pump 1 is activated. Alternatively, the alarm notification unit 33 may be set not to notify the alarm. By doing so, for example, when the medical pump 1 is started in a state where the insertion plug of the medical pump 1 is not inserted into the outlet and the charge amount of the sub-battery 43 is less than the predetermined threshold value, an alarm is issued. It is possible to prevent the notification unit 33 from immediately issuing an alarm. In this case, if the main battery 42 charges the sub-battery 43 to a predetermined threshold value or more during the second predetermined time, the alarm notification unit 33 does not need to notify the alarm, and the user uses the medical pump 1. Can start.

Even if any two of the external power acquisition unit 40, the main battery 42, and the sub-battery 43 cannot supply power during the second predetermined time after the medical pump 1 is activated, The operation of the medical pump 1 when the alarm notification unit 33 is set not to notify an alarm will be described with reference to the flowchart shown in FIG.

When the medical pump 1 is activated, the control unit 23 acquires information from the external power monitoring unit 70 whether the external power acquisition unit 40 can supply power, and the main battery monitoring unit 72 can supply power to the main battery 42. Information is acquired, and information whether the sub battery 43 can supply power is acquired from the sub battery monitoring unit 73 (step S101).

The control unit 23 determines whether or not any two of the external power acquisition unit 40, the main battery 42, and the sub-battery 43 cannot supply power (step S102).

If any two of the external power acquisition unit 40, the main battery 42, and the sub-battery 43 are not in a state in which power cannot be supplied, that is, two or more of the external power acquisition unit 40, the main battery 42, and the sub-battery 43 are When the power can be supplied (No in step S102), the control unit 23 returns to the process of step S101.

When any two of the external power acquisition unit 40, the main battery 42, and the sub-battery 43 cannot supply power (Yes in step S102), the control unit 23 starts the medical pump 1 for a second predetermined time. It is determined whether or not it is within (step S103).

If it is within the second predetermined time from the activation of the medical pump 1 (Yes in step S103), the control unit 23 returns to the process of step S101.

When the second predetermined time has elapsed from the activation of the medical pump 1 (No in step S103), the control unit 23 causes the alarm notification unit 33 to notify the alarm (step S104).

As described above, the medical pump 1 according to the present embodiment includes the main battery 42 and the sub-battery 43 that can supply electric power when the electric power is not supplied from the external electric power acquisition unit 40. The sub battery 42 can charge the sub battery 43. As a result, the main battery 42 charges the sub-battery 43 when the main battery 42 operates the medical pump 1 independently while the external power acquisition unit 40 is not acquiring power from the external power source. It becomes possible to do. Therefore, when the main battery 42 is operating the medical pump 1 while the external power acquisition unit 40 is not acquiring power from the external power source, the charge amount of the sub-battery 43 is reduced by self-discharge. Can be suppressed. Thereby, the medical pump 1 of the present embodiment can improve the convenience of the configuration including the main battery 42 and the sub battery 43.

The present invention is not limited to the configurations specified in the above-described embodiments, and various modifications can be made without departing from the scope of the invention described in the claims. For example, the functions included in each component, each step, etc. can be rearranged so as not to logically contradict, and a plurality of components, steps, etc. can be combined into one or divided. Is.

Further, in the medical pump 1 of the present embodiment, the sub-battery 43 is described as a capacitor, but the sub-battery 43 may be a secondary battery such as a lithium ion battery or a nickel hydride battery.

Further, in the medical pump 1 of the present embodiment, the control unit 23 causes the external power acquisition unit 40, the main battery 42, and the sub-battery 43 to supply electric power when the medical pump 1 is activated. When it is in a state in which the alarm cannot be performed, the alarm notification unit 33 may be set to notify the alarm without the second predetermined time.
