Now by only by the mode of embodiment and be not intended to the scope of claim and with reference to accompanying drawing The illustrative embodiment of the present invention is described, in the accompanying drawings:

Fig. 1 is schematically showing of blood pressure monitor；And

Fig. 2 is bearing calibration and the system of the blood pressure monitor including disposable tank and Fig. 1 Schematically show.

Detailed description of the invention

With reference now to Fig. 1, sphygomanometer or blood pressure monitor 10, generally it is used together with inflatable cuff 30, Inflatable cuff 30 is attached to monitor 10 by flexible pipe 20.Pipe 20 is connected to by attachment valve 12 Monitor 10, attachment valve 12 leads to passage 11, and passage 11 allows pipe 20 and pump 22 and pressure sensing Fluid communication between device 24.The output of pressure transducer is fed into analog-digital converter 26, and produces Raw digital signal is sent in processor (CPU) 28.CPU 28 controls display 29.CPU 28 operations also controlling pump 22.In use, inflatable cuff is attached to the arm 1 of patient, and makes User uses the input 32 of the part that can be display 29 to open monitoring, and input 32 is such as It is keyboard or touch-sensitive display.Pump provides the compressed air making the pressure in pipe 20 and arm straps 30 increase, Pressure transducer 24 monitors pressure simultaneously.Arm straps is generally inflated to be enough to make in the arm of patient The pressure that arterial flow stops, and then the pressure in arm straps discharged, when this section within a period of time During between, arterial flow is recovered, and the most unhinderedly flows.From arterial flow return to without hindrance Flowing, the pump action of heart causes little change in oscillation in cuff pressure.By passing via pressure Sensor 24 detects these the little vibrations above and below average pressure, and CPU can decide when to send out Raw pressure and the diastolic pressure of shrinking, and therefore, (that is, remove vibration to become by calculating potential average pressure Change) determine contraction pressure and diastolic pressure itself.

Calculate shrink pressure and the accuracy of diastolic pressure is depended on and is measured by pressure transducer 24 The accuracy of pressure.For calibrating (base measuring) pressure sensor, according to known technology, can apply exactly known Still air pressure so that the output of pressure transducer can be checked.This is generally sensitive need A series of value is repeated in the range of degree.If it is known that still air pressure and the reading of pressure transducer Between there is difference, then can regulate pressure transducer and/or processor or device other as required Parts, until monitor reflects the pressure of applying exactly.This can be such as by using CPU to come Become, to regulate pressure transducer electronically, such as, by regulating the internal amplifier of pressure transducer Gain or other parameter.

This is typically carried out during production process.But, the past in time, pressure transducer Accuracy decline.This can return and should be physical damage and collision, the environment of monitor or simply use. Therefore, over time, become, blood pressure monitor must be replaced or again correct.Generally, again Correction is carried out in the way of being similar to the initial calibration of production period.Blood pressure monitor must be attached (such as at lock valve 14) has a series of known quiescent state air pressures of high accuracy to producing The air compressor of power.It is then possible to compare reading and the expected value of pressure transducer, and if needed Want, then regulate pressure transducer.As it was previously stated, this is inconvenient, because the compression of such air Machine is expensive and is the special part of instrument, and typically requires and send instrument for measuring blood pressure back to factory with quilt Again correct.

With reference to Fig. 2, a kind of new bearing calibration again illustrates about blood pressure monitor 10.Comprise known The gas tank 16 of a certain amount of air under pressure is provided.Blood pressure monitor is placed in correction mode, Arm straps 30 and pipe 20 is made to disconnect and close the locking nut of attachment valve 12.Gas tank 16 is in locking It is attached to blood pressure monitor so that it is in fluid communication with pressure transducer at valve 14.Gas tank 16 and lock Tight valve preferably has cooperation screw thread, and lock valve includes piercing device so that gas tank can be screwed onto On lock valve, in order to realize fluid-tight seal, and simultaneously, the lid of gas tank is worn by piercing device Hole, and do not cause pressure to the loss of environment.

When gas tank 16 is perforated, the compressed air coming from gas tank is released in passage 11.Logical The volume in road 11 can be little for the volume of gas tank so that at pressure transducer 24 Pressure is extremely close to the gas pressure in gas tank.Selectively, the volume of passage can be in correction pressure Consider during force transducer, and subtract by the known of pressure caused in gas expansion to the volume of passage Make consideration less.

When at calibrating (base measuring) pressure sensor, consider that in addition to the volume of passage, instrument for measuring blood pressure can also wrap Include critesistor or other sensor for measuring temperature.Then the actual pressure varied with temperature can be made Calculate with this temperature reading read by CPU, and therefore, the correction of pressure transducer can be entered One step is improved.It should be noted that and the temperature sensor independent of bearing calibration is provided in blood pressure monitor, Making blood pressure readings can be adjusted to consider ambient temperature, this is also advantageous.

Gas from gas tank to passage in release can also cause the variations in temperature of gas, this will depend on The relative volume of pressure, tank and passage, thereby increases and it is possible to depend on the type of used gas.Although with The method of upper general introduction will allow sufficiently exact correction, but if it is required, then critesistor or other Sensor for measuring temperature 41 can be included in the channel, to compensate the pressure change owing to temperature, Or selectively, monitor can be allowed to reach and the hygral equilibrium in the room using it.

When in correction mode, the CPU of blood pressure monitor records the perseverance read by pressure transducer Constant-pressure, and this reading and the expecting pressure provided by gas tank are provided.This expecting pressure can be by using Person inputs, but is conveniently pre-programmed in CPU so that user only needs input to be printed on gas Identifier (ID) on tank, identifier can be the most digital or alphabetical, and it is also stored in In the memorizer 36 relevant to the force value of tank.Value and the identifier of storage can connect via USB Part 39 is downloaded from remote data base termly.The most advantageously, blood pressure monitor includes radio Frequency bin 25, and gas tank includes identifier, such as radio frequency identification (RFID) label 15.When gas tank is pressed close to fully (such as, when it is connected to monitor), radio frequency Receptor 25 detects and identifies gas tank, and sends it to CPU, and then CPU is at memorizer 36 The storage value of the calibrating (base measuring) pressure in middle lookup tank.

After using, gas tank is processed.Advantageously, tank is disposable to be intended for single use tank.By Not being recycling in it, therefore each tank provides the most predetermined storage calibrating (base measuring) pressure, makes Obtaining each correction example to carry out with new tank, this new tank is filled under the controlled environment of plant And seal.
