Abstract
The invention provides a sphygmomanometer capable of starting and stopping automatically, which comprises a cuff, a host and an induction unit. The induction unit consists of an induction component and an induction chip, the induction component is placed in the cuff, the induction chip is placed in the host, the host further comprises a power management unit, an MCU (microprogrammed control unit) and a pressure measuring unit, and the MCU further comprises an induction chip control subunit which is used for controlling automatic drift compensation of the induction chip; when inducing that a human body wears the cuff, the induction unit transmits a starting signal to the MCU, and the MCU outputs a signal for forbidding automatic drift compensation to the induction unit; and when inducing that the cuff is removed from the human body, the induction unit transmits a stopping signal to the MCU, and the MCU outputs a signal for recovering automatic drift compensation to the induction unit. The problem that the sphygmomanometer stops automatically due to the fact that the induction unit cannot induce that the human body still wears the cuff before the cuff is taken down after measurement is finished is avoided.
Description
Technical field
The present invention relates to a kind of sphygomanometer, design a kind of sphygomanometer of automatic switching especially.
Background technology
Along with the people in modern growth in the living standard, sphygomanometer becomes the indispensable instrument of people's daily life day by day.Existing sphygomanometer generally adopts key switch.
The application of induction chip at present more and more widely, the induction chip of convention has the automatic drift compensation function, promptly can guarantee the reliable use of inductive switch along with the sensing reference value is adjusted in the variation of environment automatically.
The user uses for ease, and the market demand adopts induction mode to realize the electric sphygmomanometer of start.And being applied to electric sphygmomanometer, induction chip has following technical problem:
After the sphygomanometer start; In the blood pressure measurement process, cuff airbag aeration deflation course reduces again after making air layer between inductive means and the human body increase; If this moment, the automatic drift compensation function of induction chip continued calibration sensing reference value; Then might occur measuring and take off before the cuff sensing unit after finishing and can not sense cuff and still be worn on the human body, then induction chip can make the sphygomanometer shutdown, thereby can not continue to measure.If the user will continue to measure, then need take off cuff, wear once more, thereby make the operation of the sphygomanometer very complicated that becomes, can not realize the measurement blood pressure of convenient intelligence.
Summary of the invention
In order to solve the problems of the technologies described above, realization can not shut down before adopting the sphygomanometer of noncontact induction technology automatic switching to take off cuff in measuring process or after the measurement end automatically, and the present invention provides a kind of sphygomanometer, comprising:
Cuff, main frame and sensing unit, said sensing unit is made up of inductive means and induction chip, and inductive means places cuff; Induction chip places main frame, and said main frame also further comprises PMU, MCU; Pressure measurement cell; Wherein, described MCU further comprises the induction chip control sub unit, is used for the automatic drift compensation of induction chip is controlled:
When sensing unit senses cuff when being worn on the human body, sensing unit is transferred to MCU with starting-up signal, and MCU forbids the automatic drift compensation signal to sensing unit output;
When sensing unit senses cuff when human body takes off, sensing unit is transferred to MCU with off signal, and MCU forbids the automatic drift compensation signal to sensing unit output cancellation.
The present invention can also take following technical scheme further to realize:
Aforesaid sphygomanometer, wherein, described sensing unit is capacitive induction unit, pyroelectricity formula sensing unit or infrared induction unit.
Aforesaid sphygomanometer wherein, also comprises a communication interface, is used for carrying out exchanges data with exterior terminal.
Aforesaid sphygomanometer, wherein, said communication interface is serial line interface, USB, bluetooth, ZigBee or WIFI interface.
Aforesaid sphygomanometer, wherein, described exterior terminal is mobile phone, PDA or PC.
Compared with prior art have following advantage at least through above structure the present invention:
Through increasing the induction chip control sub unit, the automatic drift compensation of induction chip is controlled, effectively avoided measuring and taken off before the cuff sensing unit after finishing and can not sense cuff and still be worn on the human body, thus the situation of shutdown automatically; Avoided user's troublesome operation, made blood pressure measurement convenient and swift, and simple in structure.
