Abstract

A kind of medical emergency calling for help system is made up of central station and several distress machines.When the patient who wears distress machine needs first aid, only need touch the Help Point on the distress machine, call for help function and send the radio coding distress call automatically; After central station is received signal, send sound, visual alarm automatically; Simultaneously, find calling for help person's name, sex, age, better address and medical history automatically by computing machine.Central station can send recall signal to calling for help person, makes patient know that hospital received the calling for help requirement.

Description

A kind of medical emergency calling for help system

The design belongs to lifesaving equipment Int.Cl.A62B, signalling or calling device Int.Cl.G08B.

Introduce among patent Int.Cl.A62B of China and the Int.Cl.G08B and too much plant the acute disease distress machine, all can only report to the police on the spot, can not get in touch with hospital.

Along with improving constantly of China's health care level, the mean lifetime of population improves year by year, and increasing the elderly's life security needs to look after.Now, only remain patient's worn with age situation daytime in the family, not rare.The elderly suffers from a heart complaint, cerebrovascular more.The elderly's sudden onset takes place often, and action is obstructed, the situation of aphasia and be badly in need of rescuing.In the family that has phone is arranged, and often patient can not move to the phone place, maybe can not dial, even go into a coma.In addition, pregnant woman or disabled person meet accident, and the urgent situation of rescuing of similar need is also arranged.In the city, now formed and permitted great residential block, hospital or health station are arranged in the residential block.Therefore, need a kind of emergency calling for help system that satisfies above-mentioned requirements.

Native system designs at above requirement.

This medical emergency calling for help system (referring to Fig. 1) constitutes by radio coding signal [43] contact by being arranged on the distress machine [1] that hospital's central station [2] fixing or that move and several patients carry.

The contained patient's distress machine of native system has 256, also extendible if necessary quantity.When in very short time, having the different patients who is furnished with distress machine to call for help continuously, central station can receive the distress call of different distress machines continuously, latch one by one, find respectively rapidly calling for help person name, sex, year make, better address or present position and medical history etc., and send answer signal to each calling for help person.

Its detailed functions is when patient a. falls down, to call for help function and send sound, visual alarm; B. patient pins and called for help switch 2～3 seconds, calls for help function and sends sound, visual alarm, calls for help function simultaneously and sends radio distress signal automatically; C. after radio distress signal is received at the HC station, can send the first aid alarm automatically; D. the HC station can be found automatically by computing machine, data such as the building of this patient's name, sex, inhabitation number, level, unit number and medical history; E. central station can send recall signal to calling for help person, makes patient know that hospital received calling for help; F. central station can be accepted different patients' calling for help continuously, and finds each patient's name, sex sequentially respectively, data such as the building of inhabitation number, level, unit number and medical history; G. patient's distress machine not due to illness people's mistake bump and send unwanted calling for help; H. central station can write down calling for help person name, call for help date, time, disposition etc.; I. distress machine has power switch, close the distress machine power supply after, distress machine is no longer worked.

The structure of distress machine [1] and principle of work 2,3 are described as follows in conjunction with the accompanying drawings:

Distress machine is when dormant state, because fall sensor [17] does not move, Help Point [16] was not pressed yet, the internal power supply access failure, and distress machine is not worked.

If patient stupor is fallen down when stiff, the last contact chip [20] of fall sensor [17] and descend contact chip [21] to be connected by globule [23].Through distress machine power switch [15], power supply [14] begins power supply through t2 chronotron [13] at t2 after second.At this moment, guard relay [12] action keeps the power supply power supply.Power supply, sends loudspeaker [4] to pipe directly to signal source [8] power supply through fall sensor [17], distress call lamp [7] is glittering.Do not send radio alarm signal this moment.

When pinning Help Point [16] in the time of about 3～5 seconds, through distress machine power switch [15], energized [14]; Pass through t2 chronotron [13] again, begin power supply after second at t2.At this moment, guard relay [12] action after guaranteeing that Help Point [16] discharges, can not interrupted the power supply power supply yet.Power supply is powered to scrambler [10], transmitter [9] through t1 timer [11], and sends the radio coding distress call by antenna [6]; Meanwhile, power supply is through t1 timer [11], and the signal source in distress machine [8] power supply sends loudspeaker [4] to pipe, distress call lamp [7] is glittering; T1 power failure after second, the radio coding distress call is stopped paying out automatically, and loudspeaker [4] stops to pipe.Like this, only there is t1 second in the radio coding distress call of distress machine.

When central station sends recall signal, after receiver [5] is received this signal,, loudspeaker [4] is sent: the voice signal of " hospital has received calling for help, does not please move, and bears with " through wave detector [3] and speech generator [18].This signal continues about 30 seconds, and this is by the performance decision of speech generator [18].

Power switch [15] is dialled after off-position, and distress machine loses all functions.Dial when open position, distress machine is got back to dormant state again.

In the present invention, t1 is taken as 3 seconds; T2 is taken as 2 seconds.

The safty shield [19] of Help Point [16] surrounds Help Point [16], and it exceeds Help Point [16] certain altitude.Therefore, touch unintentionally, bump distress machine [1] is sent out a signal for help.

The structure of central station and principle 4 are described as follows in conjunction with the accompanying drawings:

When patient sends radio distress signal,, after antenna [25] is received machine [24] and receives, enter wave detector [26] and handle in central station [2].The signal one tunnel that detects removes code translator [34], forms patient's address code [36] in address generator [37].This address code enters Address Register [35], is latched at this, waits for computer access.Simultaneously, another road signal enters driver [28], drives acoustic alarm device [29], visual alarm [27], sends alerting signal.Computer interface circuits [33] is reference address buffer [35] constantly, after the address code that obtains patient, read in computing machine [32] through interface circuit [33], one special software [42] operation of computing machine, find calling for help person's name, sex, the building of living number, level, unit number and medical history etc. show on display [31].

Press and answer button [39],, send the radio recall signal to patient through recall signal source [40], transmitter [41], antenna [25]; Reset signal [38] is removed alerting signal by driver [28] simultaneously, stops to report to the police, and address generator [37] is resetted, and prepares to receive next time and calls for help.

Central station uninterrupted power source [30] is 24 hours internal power supplies of power supply continuously, when external civil power interrupts in 15 minutes, can keep power supply.

Accompanying drawing 5 is the process flow diagram of special software [42].
