Description

The sick bed call monitor arrangement

Technical field

This utility model relates to sick bed call monitoring management system, and particularly a kind of employing PLC (Programmable Logic Controller) technology satisfies the ward management of hospital and the sick bed call monitor arrangement that nursing requires.

Technical background

Patient is in the while in hospital, may ask doctor or nurse to diagnose at any time or nurse, the clinical calling of seeking help is the important means that transmits clinical information, sickbed calling system is patient sends urgent call to doctor on duty or nurse a instrument, can send patient's request to doctor on duty or nurse fast, and stay accurately complete record in the Surveillance center of nurse station, be one of indispensable equipment that improves hospital and ward nursing level.

At present, comparatively Xian Jin sick bed call management system mainly adopts singlechip technology, adopts monolithic processor controlled basic composition all to need the hardware and software of being correlated with.Hardware mainly comprises single-chip microcomputer, and a large amount of peripheral interface circuit.Single-chip microcomputer and relevant integrated chip running voltage are generally 5V, and low-voltage equipments such as external equipment such as call button, display device, alarm may be direct current or interchange.Therefore must carry out level conversion and power drive, with realize single-chip microcomputer and outsidely import, the communicating by letter of output signal.If adopt low-voltage power line also must solve the information attenuation problem as transmission medium, adopt the device of setting fire to increase the transmitting terminal amplifying power, receiving terminal will be considered the coupling, filtering of information etc.

Therefore, though singlechip technology comparative maturity, the peripheral circuit more complicated, development cost is than higher.Simultaneously on software design and in use also exist defectives such as the complicated and update routine difficulty of design process.

Call button uses double-button mostly at present, calls out another shutoff for one.Obviously, to the people who is lying mortally sick differentiate its not same-action be very inconvenient.

Summary of the invention

This utility model provides a kind of PLC of employing technology ward management of satisfying hospital and the sick bed call monitor arrangement of nursing requirement especially in order to overcome the deficiency that above-mentioned prior art exists.

Because PLC can have last km telecommunication ability, so the line between sick bed call source and the PLC is very simple.Each sick bed call source signal end is by the 24V DC voltage, and direct and PLC input terminal joins, and need not to consider problems such as signal attenuation, driving.

The technical scheme that this utility model is taked is: a kind of sick bed call monitor arrangement, it is characterized in that: it comprises a PLC, the input of PLC respectively with call button on one's sick bed is installed and be installed in the medical personnel of nurse station response button, SR is connected; The outfan of PLC respectively with the sick bed label display that is installed in nurse station and sick bed number of calls statistics display, be installed in the sick bed label display of ward passage, the display lamp that is installed in nurse station and alarm, installation sick bed label display lamp and call button display lamp on one's sick bed and be connected; The outfan of PLC also is connected with transmitter receiver.

Adopt the sick bed call monitor arrangement of PLC technology to have following characteristics:

1. do not need peripheral circuit, directly be connected, so development cost is low with input/output unit, easy to utilize.

2.PLC because the simple and special I/O port of programming, for the designer provides convenience.

3.PLC interface has good load capacity, therefore has to realize simply, reliable operation is easily revised, easily the advantage of expansion.

The specific embodiment

Call out for the ease of patient, sick bed call button of the present utility model adopts crawl handle type button.The sick bed label display that be installed in the sick bed label display of nurse station and sick bed number of calls statistics display, is installed in the ward passage all adopts seven-segment display to carry out numeral demonstration.

With reference to Fig. 2, the outfan of described PLC is connected with seven-segment display by current-limiting resistance R respectively.The PLC that this utility model adopts is an example with PANASONIC FP1 series, describes its connected mode below in detail:

PLC input terminal X0～Xn and sick bed call button SB ₀～SB _nBe connected; Xn+1, Xn+2 and medical personnel's response button, SR SB _N+1, SB _N+2Be connected; The lead-out terminal Y0 of PLC～Y6 is connected with a～g end of two seven-segment displaies respectively through current-limiting resistance R, constitutes sick bed label demonstration of nurse station and the sick bed label of ward passage and shows; The lead-out terminal Y7 of PLC～YD is connected with a～g end of seven-segment display respectively through current-limiting resistance R, constitutes sick bed number of calls statistics and shows; PLC lead-out terminal YE meets alarm BZ of nurse station and transmitter receiver B; YF～Yn connects disease bed label display lamp and sick bed call button display lamp HL respectively ₀～HL _nYn+1 connects the display lamp HL of nurse station _N+1The com termination DC24V negative pole of all seven-segment displaies among Fig. 2.With reference to above-mentioned connected mode, on other PLC type, all can realize.

With reference to Fig. 3, describe the flow process of this utility model monitoring programme in detail:

1, for making things convenient for patient to use, call button adopts hand-held button structure.When patient pressed the button for the first time, sick bed display lamp, handle button display lamp were lighted, and the prompting patient has sent call request.But do not make an immediate response monitoring system at this moment, postpone 6S after supervising device just start voluntarily.If patient's maloperation, but press the button call disestablishment for the second time at 6S in the time, turn-off sick bed display lamp, handle button display lamp simultaneously.Utilize memory function in the program, note the precedence that button is pressed, make that calling out and remove calling with the button startup becomes possibility.

If 2 have patient to call out, after call monitor arrangement started, the nurse station display lamp began flicker, and buzzer warning is opened transmitter receiver, and the sick bed label of nurse station and ward passage display show Calls indicates medical personnel to make an immediate response simultaneously.Carry out medical personnel and at first press response button the display lamp of flicker is become Chang Liang, cut off and report to the police, show and to eliminate, inform that medical personnel are to in-situ processing and just in in-situ processing but call out the disease bed label.Dispose until medical personnel, remove all signals by SR.Comprise transmitter receiver, sick bed display lamp, handle button display lamp, simultaneously with nurse station display and blanking of passage display or display digit 0.

3, for increasing processing capability in real time, allow a plurality of sick beds and send calling simultaneously, this timed unit will respond Priority Call, and note secondary call signal.When medical personnel respond Priority Call, when flashing lamp was transformed to normal bright lamp, time call signal was cut automatically at once, showed simultaneously time to call out sick bed label, and the nurse station display lamp glimmers once more.

4, for improving the scientific management of hospital, grasp the lesion patient care situation of having jurisdiction over, also be convenient to understand medical personnel's on duty working strength, this device increased in certain time period to be added up patient's number of calls.Can set timing statistics arbitrarily according to school's requirement, as 8 hours or 24 hours etc.In locking time, incite somebody to action show Calls number of times at any time, and the circulation of deadline automatically, go round and begin again.Calling adds 1 statistical signal takes from medical personnel and presses SR, to guarantee the accuracy of record.
