Apparatus for receiving liquid treatment samples for disposal

A system for removing treated blood samples from a blood corpuscle concentration measuring device comprising:

• a container for holding blood samples for measurement;
• a closed vessel;
• a pressurization means for controlling pressure within the closed vessel;
• a pressure sensor for measuring pressure within the closed vessel and providing a signal;
• a means for controlling fluid communication between the container and the closed vessel based upon the signal provided by the pressure sensor, the means for controlling including a valve controlling circuit for controlling an opening and closing operation of a valve disposed within a conduit, the conduit providing fluid communication between the container and the closed vessel, the valve controlling circuit indicating the beginning of a waste solution collection cycle and opening the valve;
• and
• a warning circuit for indicating a lapse of a predetermined time limit from the beginning of the waste solution collecting cycle.

An apparatus for measuring corpuscle concentration within blood samples, comprising:

• a treating vessel for subjecting a sample to a measurement treatment;
• a closed liquid waste vessel, the closed vessel receiving the treated sample through a conduit communicating with treating vessel;
• a valve midway along the conduit, the valve opening and closing the conduit;
• a pressure reducing means for reducing a pressure within the closed vessel to a first preset pressure level;
• a pressure sensor for detecting the pressure within the vessel;
• a valve controlling means for opening the valve to allow sample communication along the conduit and for closing the valve when the pressure sensor detects the pressure within the closed vessel has risen above a second preset level, the second preset level corresponding to an emptying of the treatment vessel;
• and
• an alarm providing an alarm signal when the pressure level does not rise to the second preset level within a predetermined time period from the opening of the valve.
