Weighing system

A weighing system that facilitates keeping a nursing record for a subject, the subject being assigned an identification number that is stored by an identifier, said weighing system comprising:

• a reader configured to read the identifier to obtain the identification number of the subject;
• a weight scale configured to support an object, to measure weight of the object, and to output an entry of weight data indicating the weight of the object currently measured;
• a processor disposed in said weight scale, electrically connected to said reader and said weight scale, and configured to receive the identification number of the subject from said reader, to receive the entry of weight data from said weight scale, and to operate in one of an intake mode and an output mode;
• a mode switch disposed on said weight scale, electrically connected to said processor, and configured to be operated to enable said processor to operate in one of the intake mode and the output mode;
• a display disposed on said weight scale, electrically connected to said processor, and configured to be controlled by said processor to display the identification number of the subject;
• a memory device disposed in said weight scale, and electrically connected to said processor;
• an intake-type button set disposed on said weight scale, electrically connected to said processor, and including a plurality of intake-type buttons that respectively correspond to a plurality of intake-type visual symbols which are respectively related to a plurality of types of intake substances;
• and
• an output-type button set disposed on said weight scale, spaced apart from said intake-type button set, electrically connected to said processor, and including a plurality of output-type buttons that respectively correspond to a plurality of output-type visual symbols which are respectively related to a plurality of types of output substances,
• wherein said processor is further configured, when operating in the intake mode, to
• determine whether any one of said intake-type buttons and said output-type buttons is pressed,
• when it is determined that one of said intake-type buttons is pressed, control said display to display one of the intake-type visual symbols that corresponds to the one of said intake-type buttons, and then in response to receipt of the entry of weight data from said weight scale, obtain a first value of intake-related weight based on the entry of weight data, control said display to display the first value of intake-related weight, and store the first value of intake-related weight in said memory device, and
• when it is determined that one of said output-type buttons is pressed, not control said display to display any one of the output-type visual symbols,
• wherein said processor is further configured, when operating in the output mode, to
• determine whether any one of said intake-type buttons and said output-type buttons is pressed,
• when it is determined that one of said output-type buttons is pressed, control said display to display one of the output-type visual symbols that corresponds to the one of said output-type buttons, and then in response to receipt of the entry of weight data from said weight scale, obtain a first value of output-related weight based on the entry of weight data, control said display to display the first value of output-related weight, and store the first value of output-related weight in said memory device, and
• when it is determined that one of said intake-type buttons is pressed, not control said display to display any one of the intake-type visual symbols.
