Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
104 words
A bio-medical device for monitoring body liquid output comprising: container means having a single receptacle for receiving a critical volume of body liquid and for discharging the liquid upon being filled with the critical volume; means pivotally supporting said receptacle within said container for an oscillatory motion between a liquid filling normal position and a liquid discharge position; counting means responsive to each discharge, for monitoring the total volume of liquid flow via said container means; a liquid collection bag connected with said container means; and, separation means in said container for accumulating the sediment in the liquid passing to the liquid collection bag.
Claim 2
Dependent Claim
104 words
A bio-medical device for monitoring body liquid output comprising: container means having a single receptacle for receiving a critical volume of body liquid and for discharging the liquid upon being filled with the critical volume; means pivotally supporting said receptacle within said container for an oscillatory motion between a liquid filling normal position and a liquid discharge position; counting means responsive to each discharge, for monitoring the total volume of liquid flow via said container means; a liquid collection bag connected with said container means; and, separation means in said container for accumulating the sediment in the liquid passing to the liquid collection bag.
Claim 3
Dependent Claim
14 words
A bio-medical device according to claim 1 wherein said separation means includes a standpipe.
Claim 4
Dependent Claim
124 words
A bio-medical device for monitoring body liquid output comprising: container means having a single receptacle for receiving a critical volume of body liquid and for discharging the liquid upon being filled with the critical volume; means pivotally supporting said receptacle within said container for an oscillatory motion between a liquid filling normal position and a liquid discharge position; counting means responsive to each discharge, for monitoring the total volume of liquid flow via said container means; frame support means for removable receiving said container adapting the container for disposable purposes; said counting means including sensor means mounted on said frame support means for generating an electrical output signal with each receptacle discharge; and means for pivotally suspending said support means about a pivotal connection.
Claim 5
Dependent Claim
124 words
A bio-medical device for monitoring body liquid output comprising: container means having a single receptacle for receiving a critical volume of body liquid and for discharging the liquid upon being filled with the critical volume; means pivotally supporting said receptacle within said container for an oscillatory motion between a liquid filling normal position and a liquid discharge position; counting means responsive to each discharge, for monitoring the total volume of liquid flow via said container means; frame support means for removable receiving said container adapting the container for disposable purposes; said counting means including sensor means mounted on said frame support means for generating an electrical output signal with each receptacle discharge; and means for pivotally suspending said support means about a pivotal connection.
Claim 6
Dependent Claim
81 words
A bio-medical device for monitoring body liquid output comprising: disposable container means including a pivotal receptacle means for receiving a specific volume of body liquid and for dumping the liquid upon being filled with the specific volume; assembly means adapted for pivotal suspension and for removably receiving said disposable container means; and counting means including sensor means mounted on said assembly means and responsive to each receptacle means dump, for monitoring the total volume of liquid flow via said receptacle means.
Claim 7
Dependent Claim
81 words
A bio-medical device for monitoring body liquid output comprising: disposable container means including a pivotal receptacle means for receiving a specific volume of body liquid and for dumping the liquid upon being filled with the specific volume; assembly means adapted for pivotal suspension and for removably receiving said disposable container means; and counting means including sensor means mounted on said assembly means and responsive to each receptacle means dump, for monitoring the total volume of liquid flow via said receptacle means.
Claim 8
Dependent Claim
38 words
A bio-medical device according to claim 4 whereby said receptacle is provided with a configuration to cause a shift in the receptacle center of gravity when filled, to be impelled from the normal position to the discharge position.
