Embodiment Construction

[0055] The heat therapy device is assigned the reference numeral 1 in its entirety.

[0056] according to figure 1 , the thermal therapy device 1 includes an inner space 9 in which the patient 8 is located. Patient 8 is especially a premature infant (newborn). In this case, the thermotherapy device 1 is a closed thermotherapy device 1 , ie the inner space 9 is closed from the environment.

[0057] The motor 2 is arranged on the wall 11 , wherein the motor 2 is arranged outside the interior 9 . In a first embodiment, the motor 2 has a motor type-dependent fixed target speed. In a further alternative embodiment, a setpoint value signal input 22 is provided on the motor 2 for actuation, via which the motor 2 receives a setpoint value for the setpoint rotational speed from the outside.

[0058] Furthermore, the motor 2 comprises a parameter signal output 23 via which parameters of the motor 2 can be output. In this case, the parameter is an operating parameter of the motor 2 ...

Abstract

The invention relates to a thermal therapy apparatus (1) having a motor (2) for releasable connection to a fan wheel (3), wherein the motor (2) has a parameter signal output (23), wherein according to the invention provided that the thermal therapy apparatus ( 1) an evaluation unit (4) (with a parameter-signal input terminal 45), wherein (the motor (2) via the parameter signal output 23) transmits a time dependent parameter signal to the parameter signal input (45) and the evaluation unit (4 ) comprises a default value module (41) and a comparator (42), said replacement value module (41) (from the (between the starting of the engine 2) and the attainment of a desired speed of the engine 2) determined time-dependent parameter signal a substitute value for the is motor (2) is accelerated moment of inertia and the comparator (42) for comparing the replacement value formed with a predetermined threshold value. Further, a corresponding method is the subject of the invention. With the invention, an apparatus and method are provided that can detect a missing fan with little effort quickly and reliably.

Description

technical field [0001] The invention provides a thermotherapy device with a motor for detachable connection to a fan impeller, wherein the motor has a parameter signal output. [0002] Patients requiring a constant ambient temperature are treated in a thermotherapy device. The ambient temperature is generally also heated. In this case, the thermotherapy device, which can be configured as an incubator, includes a fan impeller for air circulation in order to avoid thermal inhomogeneities in the thermotherapy device and the resulting health risks for the patient. The fan wheel is motorized and removable from the motor for easy cleaning. However, there is the risk that the ventilator is no longer attached to the motor after cleaning by mistake. Air circulation can no longer be generated afterwards. This can pose a health risk for the patient. Background technique [0003] In order to avoid this risk, it is known to place a sensor below the fan wheel, which sensor detects th...
