Abstract
A blood pressure measuring apparatus which comprises: a memory which stores the pressure value of a cuff when the cuff is to be pressurized again after the cuff has been pressurized; a comparator which, after the cuff is pressurized again, compares the pressure value of the cuff with the stored pressure value; a controller which produces an additional driving signal when the former in not greater than the latter; and a pump which pressurizes again the cuff in response to the additional driving signal.
Claims3
In a blood pressure measuring apparatus, comprising a pressure applying means, a measuring means which measures the pressure of said pressure applying means, a control means which produces a driving signal, and a pressure means which pressurizes said pressure applying means in response to said driving signal,
- said apparatus further comprises:
- a memory means which stores the pressure value of said pressure applying means when said pressure applying means is to be pressurized again after said pressure applying means has been pressurized;
- and
- a comparing means which, after said pressure applying means is pressurized again, compares the pressure value of said pressure applying means with said stored pressure value,
- said control means produces an additional driving signal when the former is not greater than the latter, and
- said pressure means pressurizes again said pressure applying means in response to said additional driving signal,
- wherein said additional driving signal comprises one short pulse at its beginning.
In a blood pressure measuring apparatus, comprising a pressure applying means, a measuring means which measures the pressure of said pressure applying means, a control means which produces a driving signal, and a pressure means which pressurizes said pressure applying means in response to said driving signal,
- said apparatus further comprises:
- a memory means which stores the pressure value of said pressure applying means when said pressure applying means is to be pressurized again after said pressure applying means has been pressurized;
- and
- a comparing means which, after said pressure applying means is pressurized again, compares the pressure value of said pressure applying means with said stored pressure value,
- said control means produces an additional driving signal when the former is not greater than the latter, and
- said pressure means pressurizes again said pressure applying means in response to said additional driving signal,
- wherein said control means repeatedly produces said additional driving signal until the pressure of said pressure applying means reaches a predetermined value.
