1. A medical pump drive comprising:
a pump housing;
a pump motor arranged in the pump housing, the pump housing comprising:
a distal end comprising a base section for positioning the pump drive onto a base surface; and
a proximal end comprising a connecting section for connecting the pump drive to a pump section;
an induction charging coil situated in the distal end of the pump housing;
a rechargeable voltage source for storing electrical energy, or a rechargeable battery, for a power supply of the pump motor;
a magnetic section for magnetically coupling or magnetically driving components of a magnetically driven pump rotor; and
an electronic controller comprising or connected to a motion sensor, the motion sensor configured to detect movement of the pump drive, the movement comprising a rotation of the entire pump drive, wherein the electronic controller is configured to determine an orientation of the pump drive,
wherein the electronic controller is configured to activate the magnetic section of the pump drive to transfer the pump drive from a first state to a second state in response to determining that the pump drive is in a first orientation, wherein the magnetic section is configured to magnetically couple or magnetically drive the components of the magnetically driven pump rotor when the magnetic section is activated in the second state, and wherein the electronic controller is configured to deactivate the magnetic section of the pump drive to transfer the pump drive from the second state to the first state in response to determining that the pump drive is in a second orientation, wherein the magnetic section is configured to stop magnetically coupling or magnetically driving the components of the magnetically driven pump rotor when the magnetic section is deactivated in the first state.
