Peritoneal dialysis machine having a torque limiting device

A peritoneal dialysis machine comprising:

• a machine housing and having a weighing pan for receiving one or more solution bags, the weighing pan being connected to a weighing cell for weight measurement;
• at least one torque limiting device which prevents an occurrence of a torque or of a torque exceeding a limit value in the weighing cell, with the torque limiting device being configured such that, with a torque acting on the weighing pan, it moves the weighing pan such that it comes into contact with the machine housing or with an element connected to the machine housing such that the torque is led off into the machine housing or into the element;
• said torque limiting device having a first element and a second element, said first element being formed by a body which has a recess of which at least one surface extends at an inclination with respect to the horizontal and with respect to the vertical, said second element being received in the recess, with the first element being rotatable relative to the second element;
• and
• said torque limiting device including a torsion spring that has a first section which is connected to the weighing pan or to a body arranged at the weighing pan and is subjected to torsion on a tilt movement of the weighing pan.
