## Abstract

Provided is a medical pump for achieving continuous administration of a medicine by performing sequential driving with another medical pump. The medical pump includes: a pump driving unit for administering the medicine in accordance with a setting; a communication unit for performing communication between the other medical pump; a control unit for controlling individual driving of the pump driving unit and the communication unit; and an operation unit connected to the control unit. In a single administration period, the control unit judges a timing of starting cooperative administration of simultaneously driving the pump driving unit together with a pump driving unit of the other medical pump on the basis of the setting and on the basis of an input from the operation unit.

## Claims

### Claim 1

A medical pump comprising:
a pump driving unit that administers a medicine in accordance with a setting associated with the medicine;
a communication unit that performs communication between the medical pump and a second medical pump;
a control unit that controls the pump driving unit and the communication unit; and
an operation unit in communication with the control unit, wherein the operation unit controls the administration of medicine by the medical pump and the second medical pump, and wherein, during the continuous administration of the medicine by the medical pump and then the second medical pump, the control unit determines when to start a cooperative administration period for administering the medicine with the first medical pump and the second medical pump by concurrently driving the pump driving unit and a second pump driving unit of the second medical pump based on the setting and a manual input received from the operation unit.

### Claim 2 (depends on 1)

The medical pump according to claim 1, further comprising a display unit configured to display start information for starting the cooperative administration period by the manual input received from the operation unit.

### Claim 3 (depends on 2)

The medical pump according to claim 2, further comprising a display unit configured to display a scheduled time, based on the setting, until the cooperative administration is started.

### Claim 4

A medical pump system comprising:
a first medical pump comprising:
a first pump driving unit that administers a medicine, associated with the first and a second medical pump, in accordance with a setting;
a first communication unit;
a first operation unit to receive a manual input;
a first control unit that:
judges, in a first time period, a first time to start a cooperative administration period for administering the medicine;
concurrently drives the first pump driving unit and a second pump driving unit of the second medical pump based on the setting and the manual input;
the second medical pump, that, with the first medical pump, continuously administers the medicine by sequential driving the first and second medical pumps, wherein the second medical pump comprises:
the second pump driving unit that administers the medicine associated with the second medical pump;
a second communication unit in communication with the first communication unit; and
a second control unit that concurrently drives the second pump driving unit based on a signal received from the first control unit through the first communication unit.

### Claim 5

A method for controlling a medical pump system, the method comprising:
receiving a setting at a first control unit of a first medical pump, wherein the first medical pump is in communication with a second medical pump;
receiving an input from an outside source at the first medical pump;
during a first administration period, a control unit of the first medical unit determining a start time for a cooperative administration period for administering a medicine, associated with both the first medical pump and the second medical pump, wherein the start time is determined based on the setting and the input;
after the start time occurs, the first control unit driving a first pump driving unit to administer the medicine; and
after the start time occurs and while the first control unit is driving the first pump driving unit to administer the medicine, a second control unit driving a second pump driving unit to administer concurrently the medicine with the second pump.

### Claim 6 (depends on 2)

The medical pump according to claim 2, wherein the control unit controls the concurrently driving of the first and second medical pumps based on a W method.

### Claim 7 (depends on 6)

The medical pump according to claim 6, wherein a first administration rate of the first medical pump is decreased in stages while a second administration rate of the second medical pump is concurrently increased in stages in the W method.

### Claim 8 (depends on 7)

The medical pump according to claim 7, wherein the start time begins the cooperative administration period when the first administration rate and the second administration rate are changed.

### Claim 9 (depends on 8)

The medical pump according to claim 8, wherein the display unit receives the manual input into an interface.

### Claim 10 (depends on 9)

The medical pump according to claim 9, wherein the control unit determines if cooperative administration is possible.

### Claim 11 (depends on 10)

The medical pump according to claim 10, wherein the control unit sends a cooperative administration start signal to the second medical pump to begin the cooperative administration period.

### Claim 12 (depends on 11)

The medical pump according to claim 11, at an end of the cooperative administration period, the second medical pump alone administers the medicine.

### Claim 13 (depends on 12)

The medical pump according to claim 12, wherein a second display unit on the second medical pump displays a warning of an end of the medicine administration.

### Claim 14 (depends on 13)

The medical pump according to claim 13, wherein the second medical pump receives a manual input to stop administration of the medicine.

### Claim 15 (depends on 5)

The method according to claim 5, wherein the control unit controls the concurrently driving of the first and second medical pumps based on a W method.

### Claim 16 (depends on 15)

The method according to claim 15, wherein a first administration rate of the first medical pump is decreased in stages while a second administration rate of the second medical pump is concurrently increased in stages in the W method, wherein the start time begins the cooperative administration period when the first administration rate and the second administration rate are changed.

### Claim 17 (depends on 5)

The method according to claim 5, wherein the control unit determines if cooperative administration is possible.

### Claim 18 (depends on 5)

The method according to claim 5, wherein a first display unit of the first medical pump receives the manual input into an interface.

### Claim 19 (depends on 5)

The method according to claim 5, wherein the control unit sends a cooperative administration start signal to the second medical pump to begin the cooperative administration period.

### Claim 20 (depends on 5)

The method according to claim 5, at an end of the cooperative administration period, the second medical pump alone administers the medicine.
