A kind of sphygomanometer with wireless transmission function
Technical field
This utility model belongs to the armarium technical field, is specifically related to a kind of sphygomanometer with wireless transmission function.
Background technology
Measuring blood pressure is an important instrument of medical diagnosis on disease on the clinical medicine (cardiovascular disease).Traditional blood pressure measuring method is to use sphygomanometer to measure blood pressure, namely uses sphygomanometer to cooperate an inflatable blood pressure cuff to measure on the arm of human body or thigh.The trachea of cuff is connected on the compression pump (controlled air pump), inflates to cuff with compression pump, make the pressure that reaches certain in the cuff after, cuff can push the arteries on the arm, limit blood flowing in aorta.At this moment, medical personnel open air valve slowly exits cuff, listen attentively to the sound that blood flows with stethoscope in blood vessel simultaneously, and observing sphygomanometer upward pressure value, medical personnel can diagnose patient's pressure value (systolic pressure and diastolic pressure) according to the variation of blood Ke Shi sound in the whole process like this.Above-mentioned this auscultation measurement blood pressure need be used device and comprise: mercurial sphygmomanometer, non-invasive blood pressure cuff and stethoscope.The personnel that the blood pressure measurement of this mode needs the doctor or accepted professional training utilize stethoscope to judge and systolic pressure and the diastolic pressure of record patient in measuring process.Though what this blood pressure measurement mode was general is accepted as standard clinically, because the hydrargyrum of filling in the mercurial sphygmomanometer is poisonous heavy metal, in case reveal the safety that will jeopardize the patient; In addition, when reading the sphygomanometer reading, its reading of different medical personnel is different, has certain deviation, and therefore in this rugged environment of clinical particularly first aid, this blood pressure measurement mode is difficult to adapt to the measurement needs.
At present, existing relevant full-automatic electronic digital sphygmomanometer on the market, it need not pinching ball inflation pressurization, only needs the Push switch key, just can finish measurement automatically; But existing full-automatic electronic sphygomanometer is not owing to self arrange wireless module, during use, people often need the scene to see and listen measured data, can not with computer and the Internet, measurement data only rests on this board, can't realize remote diagnosis medical treatment and the function of monitoring; Also can't satisfy remote monitoring patient blood pressure, the demand of long-range understanding relatives blood pressure.
