Abstract

The utility model relates to a multifunctional automatic monitoring prealarm for hearts, which is composed of a transmitter and a receiver. Heart rate signals are picked up by the frequency modulating transmitter and received by the receiver and then processed by a magnifying and frequency multiplier to be sent to a central controller to carry out counting, code translation and multidigit driving to display the heart rate number of per minute. When the heart rate number is over 100 times/m and below 50 times/m, the alarm is carried out; the receiver is provided with a jack connected with an interior circuit; a temperature probe can be matched to measure body temperature; any timing within 0.01 second to 9999 seconds can be carried out. The utility model has the advantages of high accuracy, small volume, low voltage and low consumption, and heart changes can be monitored continuously for a long time.

Description

Multifunctional automatic monitoring prealarm for heart

This utility model is to be used for the heart patient can award the monitoring warning before state of an illness outbreak, belongs to medical instruments field.

The traditional monitoring instrument belonged to substantially that volume is big, supply voltage is high, price is high too, complicated operation in the past, with regard to the also non-people of its weight can and, general people also is difficult to grasp the long-term monitoring that can't finish patient." pocket heart monitor (CN2042344) and the portable heart report to the police automatically first aid device (CN209114) " that China's utility model patent communique was once announced, though these two patented technologies have obtained progress to a certain extent, but exist following different separately shortcoming: one, be no any cardiac function data show on the machine, patient and doctor can not ocular and clear heart rate situations, need row test again, affect adversely and take medicine and rescue time; Two, be that this circuit adopts that the loss of signal of A/D conversion regime is many, precision is low, error is big; Three, be that the testing time is long, needed just can give the alarm in one minute approximately, and heart attack generally should be taken measures before the half at one minute; Four, be difficult use of patient at night, " pocket cardiac monitor " is with the received signal of body own, can't wear night at body, do not have the warning effect, " portable heart report to the police automatically rescuring device " it is upright or sit up straight posture and just can use the patient, and the patient tilts to a certain degree and just reports to the police, and has a rest or can't start shooting in bed evening in case patient wants to lie down, and cardiac's sickness rate at night is very high, so do not have practical function; Five, be that volume is big, complex circuit, power consumption be quite big.

The purpose of this utility model just is to have avoided equipment and defective of the prior art in the past, can make heavy many cardiacs guard the state of an illness for a long time continuously, especially solving night is heart attack and dead high-incidence season during Buddhist is known, because of people ignore the serious consequence that the observation to patient takes place, the appearance of this instrument provides reliable assurance to heart patient's life security.

This utility model is to realize with following technical proposal: this multifunctional heart automatic monitoring early-warning apparatus is by transmitter, receiver two parts are formed, wherein transmitter is connected and composed by sampling detector (3-1), signal amplifier (3-2) and frequency-modulated transmitter (3-3), described receiver comprises reception amplifier (5-1), shaping circuit (5-2), double-frequency oscillation device (5-3), and the count pulse of double-frequency oscillation device (5-3) output is sent into master controller (5-5) counting behind shaping circuit (5-4); Described master controller (5-5) is by a large scale integrated circuit 6IC3(DNL9203) constitute, this chip 6IC3 include time counter (UDCT), digital comparator (COMP), latch (REG), decoder (MXBLD), agitator (CLK), frequency divider (FD) and the time base output and circuits for triggering (R/S), reach the standard grade coding circuit (5-6) and the coding circuit that rolls off the production line (5-7) inserts numeral respectively, and 6IC3(DNL9203) the internal trigger circuit directly inserts and drives alarm Q and report to the police.

Advantage of the present utility model:

1, midget receiver has the digital display screen curtain, can show wearer's heart rate situation, offers precise data to patient and doctor.

2, no matter wrist-watch shape transmitter works by day, night sleep only need can guarantee the reliability of early warning with going up " wrist-watch ", and receiver can be placed near the head of a bed, daytime as beeper wear on one's body, all can receive the signal that sends in two meters.

3, short, circuit simple (being that core devices is formed mainly) of testing time by large scale integrated circuit, the few precision height of the loss of signal.

4, with the measurement of bldy temperature meter, still be the thought-read rate by dialling position switch control thermometric, the connection jack that existing temperature transducer directly inserts receiver just can use.

5, adopt ternary own coding switch, the user can set up the fixed time call time on their own, takes medicine on time to remind patient.

6, receive that casing is outer can attach project cards such as patient's name, age, address, phone, blood group, medical history, also have indispensable medicine simultaneously, help accurately and give first aid in case meet accident in time to provide.
