<p>The invention relates to a device for sensing the presence of the distal end of a source wire in a reference position within a guidance channel of an afterloading apparatus. <??>The invention aims to provide an afterloading apparatus provided with a sensing device which is capable of more accurately and reliable detecting the presence of the distal end and more in particularly the presence of the energy emitting source at its reference position, allowing a safer handling of the energy emitting source and thus avoiding hazardous and harmful situations. <??>According to the invention the sensing device is characterized in that a lever element is pivotally mounted near said guidance channel, which lever element is in a first position, when said distal end of said source wire is not present in its reference position and whereas said lever element is in a second positon, when said distal end is present in its reference position. <??>With this embodiment it is possible to sense the presence of the distal end and the energy emitting source at several important operational positions within the afterloading apparatus or patient, thus allowing a more exact positioning of the energy emitting source into the patient's body. <IMAGE></p> |
