Problems solved by technology
This is expensive and inconvenient; moreover, the blood pressure monitor can be dropped or damaged during shipment back from the calibration company, making the blood pressure monitor again inaccurate
[0006] Because of these problems, although all consumer blood pressure monitors are calibrated during production, many are never recalibrated
This of course negatively affects the quality of diagnosis and treatment for the millions of blood pressure monitor users

Embodiment Construction
[0041] now refer to figure 1, a sphygmomanometer or blood pressure monitor 10 is typically used with an inflatable cuff 30 attached to the monitor 10 by a flexible tube 20 . Tube 20 is connected to monitor 10 through attachment valve 12 which leads to passage 11 which allows fluid communication between tube 20 and pump 22 and pressure sensor 24 . The output of the pressure sensor is fed to an analog-to-digital converter 26 and the resulting digital signal is sent to a processor (CPU) 28 . The CPU 28 controls the display 29 . CPU 28 also controls the operation of pump 22 . In use, the inflatable armband is attached to the patient's arm 1 and the user starts monitoring using an input 32 which may be part of the display 29, such as a keyboard or a touch sensitive display. The pump provides compressed air which increases the pressure in the tube 20 and cuff 30 while the pressure sensor 24 monitors the pressure. The cuff is typically inflated to a pressure sufficient to stop ar...

A blood pressure monitor, particularly of the type having an inflatable cuff communicating with a pressure sensor and suitable for home use, may be calibrated by applying a sealed canister containing gas at a known pressure to a port so as to apply the known pressure to the pressure sensor, and comparing a pressure signal from the pressure sensor with the known pressure so as to determine a calibration error of the sensor and / or adjust the calibration of the sensor, e.g. by electronically adjusting the sensor. Several canisters may be used to calibrate the sensor across a range of pressures, each canister having a different known pressure.; Each canister is preferably ruptured when attached to the port and is not re-usable, and may comprise an identifier such as an electronically readable identifier which is stored in a memory in association with the value of the known pressure within the canister. Temperature sensing means may be provided whereby the pressure reading is adjusted to compensate for temperature, e.g. of the gas released from the canister. The monitor may comprise means for sensing mechanical shock and alerting a user or remote monitoring personnel to provide an indication that recalibration is required.
Description
[0001] This application is a divisional application of the application with the application number 201180034332.6, the application date is July 25, 2011, and the invention title is "Blood Pressure Monitor Calibration". technical field [0002] The present invention relates to calibration of blood pressure monitors, particularly calibration of blood pressure monitors using known pressures. Background technique [0003] Cardiovascular disease (CVD) is the cause of one third of global deaths and is a major and increasing cause of the global burden of disease. Hypertension is already an extremely prevalent risk factor for CVD throughout the industrial world and is becoming an increasingly common health problem in many developing countries, especially in urban societies. [0004] Accurate measurement of blood pressure is essential for the successful management of hypertension. Blood pressure is usually measured with a sphygmomanometer or blood pressure monitor. One of the main ...
