Description
Technical field
The present invention relates generally to the human body physiological parameter measuring technique, particularly a kind of device that can utilize the biology sensor that is built in wireless mobile communication device the multinomial physiological parameter of human body to be measured and measurement result can be sent to the tele-medicine facility.
Background technology
For the adult, if systolic pressure is higher than 140mmHg or diastolic pressure is higher than 90mmHg, promptly to suffer from hypertension.Blood pressure when systolic pressure is heart contraction, and the blood pressure of diastolic pressure when being diastole.Hypertension has become big serious problems of public health.Most of hyperpietics do not have symptom at the initial stage.Therefore, if in the untimely treatment of ill initial stage, have in the future very big chance cause can be fatal heart disease.When the symptom performance was arranged, it is more serious that the patient's condition has become.People recognize day by day influence that hypertension is brought health promoted individual monitoring of blood pressure technology development.The introspection blood pressure can reduce the number of times of patient to the clinic.In the U.S., probably there are 50,000,000 people to suffer from hypertension, and, probably have 100,000,000 people to suffer from hypertension in China.Blood pressure measuring instrument can be divided into two big classes: damaged formula and do not have damaged formula.The instrument that does not have damaged formula is fit to introspection and use at home.In the middle of the instrument of no damaged formula, wherein a kind ofly be based on the pulse wave transmission time (Pulse TransitTime-PTT).In the pulse wave transmission time, when being meant heart contraction, arterial pulse wave passes to not tip artery position (for example: point) the needed time from sustainer.The reference point of representing the heart contraction time can be with the corresponding electrocardiosignal of each heartbeat in the summit of R type ripple.The time reference of representing the tip arterial pulse wave to arrive the tip position can be the summit with the corresponding smooth plethysmographic signal of each heartbeat.By the pulse wave transmission time that obtains, can at first will definitely arrive a tropic, and calculate relevant pressure value.This pressure value method for measuring is no damaged formula, need also can not carry out with each heartbeat form with any wrist strap air bag.
Global population just is being tending towards aging.In the year two thousand fifty, the age will be up to nearly 2,000,000,000 at threescore or above population, and the elderly's number will surpass children's number for the first time on human history.Because the elderly's disease majority is a chronic disease, so the patient monitoring system in the tele-medicine can provide required medical services to the elderly effectively.Mobile radio terminal instruments such as mobile phone and palm digital assistant mobile phone are being employed already in real time and in the tele-medicine of storage/forwarding.In 2002, whole world mobile phone user's number surpassed 1,000,000,000.This numeral is expected will reach 2,000,000,000 in the end of the year 2009, and promptly the popularity rate of mobile phone is about 31%.
Can see the expansion in mobile communication market and people needs from above data to the monitoring of blood pressure instrument.Therefore, this show have built-in sensors, can be used for introspection and distant apart from the monitoring physiological parameter (especially blood pressure) portable radio will be an instrument of great use.
In U.S. Patent No. 4,869,262 and U.S. Patent No. 5,316,008 in a kind of blood pressure measuring instrument based on the pulse wave transmission time is disclosed respectively.Though wherein said instrument is of portable form and is easy to use, they all are short of radio communication function, can not transmit the data that obtain toward other place.In U.S. Patent No. 6,396,416 disclose a kind of extra cell that can be connected on the ambulatory handheld instrument.This unit can be equipped with different transducers, does not measure the different parameters that comprises pressure value in order to there to be damaged formula ground.This unit by using volume is clamped down on the method for (Volume Clamp) and is measured pressure value, and its assembly that needs comprises: wrist strap air bag, air pump, air valve, infrared transmitter and infrared receiver.Though this invention has the function of blood pressure measurement and radio communication, this unit is an add-on module.In addition, the volume that this instrument uses is clamped down on method and is unwell to mobile purposes, because this method needs a plurality of mechanical parts and is subjected to the motion The noise easily.
