Description

Inpatient pulse wireless monitoring system

technical field

The utility model relates to a wireless monitoring system, in particular to a pulse wireless monitoring system for hospitalized patients.

Background technique

The pulse is the pulsation of the artery. With the rhythmic contraction and relaxation of the heart, when the heart contracts, the arterial beating caused by the impact of the output blood causes the arterial wall to expand and retract accordingly, and the pulsation can be felt on the superficial artery. Because the heart contracts and relaxes, the arterial pressure rises and falls; and because the arterial wall is rich in elastic fibers, the rise and fall of the arterial pressure can start from the aorta in the form of pulse waves and move rapidly along the wall. Spread to each branch artery until the end of the arteriole. The pulse frequency is the pulse rate. The pulse and heartbeat of normal people are consistent. The pulse rate is 60 to 100 beats per minute. The elderly are slower at 55 to 60 beats per minute. The pulse rate is regular and equal in strength and pulse will not appear. The phenomenon of varying intervals and alternation of strength and weakness. . The pulse frequency is affected by age and gender. Infants are 120-140 beats per minute, young children are 90-100 beats per minute, and school-age children are 80-90 beats per minute. In addition, exercise and emotional agitation can make the pulse faster, while rest and sleep make the pulse slow down. Adults with a pulse rate of more than 100 beats per minute are called tachycardia; those with a pulse rate lower than 60 beats per minute are called bradycardia. There are many clinical diseases, especially heart disease, which can make the pulse change. Therefore, measuring the pulse is an indispensable inspection item for the patient. Traditional Chinese medicine regards pulse cutting as the main method of diagnosis and treatment of diseases. In a critical condition, especially before death, the number and pulse rate of the pulse will change significantly. The change of the pulse is also one of the basis for the doctor to diagnose the patient. The pulse is an important vital sign of the human body, and the presence or absence of the pulse is also an important sign of whether life is alive. At present, the pulse detection of patients is mainly monitored by detectors, but the equipment can only be used alone, and the distance is limited. The observation of hospitalized patients basically adopts the method of inspection and palpation. Since visual inspection is completely manual, the efficiency is low. Especially at night, due to the lack of nurse manpower resources, nurses may not be able to find out some unexpected sudden condition changes immediately.
