Abstract
The invention discloses a respiratory failure monitor which consists of a resistance wire and a control circuit. The resistance wire is bent into a certain shape and clamped between two pieces of fiber cloth to be integrated. When in monitoring, the monitor is fixed on the abdomen of a patient. When the patient breathes, change in length of the resistance wire results in the change of resistance value of the resistance wire, and after the differential amplification carried out by an operational amplifier, low level is output through that phase inversion is performed by a phase inverter. The low level triggers a time-delay circuit to output low level so as to block an audion and ensure that a buzzer does not give an alarm. At this moment, the time-delay circuit performs time delay. When no breath signal is detected within the set delay time, an output end of the time-delay circuit changes from low level to high level, the audion is conducted and the buzzer gives an alarm, i.e., that when breath signals can not be detected if the patient does not breathe or shallowly breathe, an alarm is given, but if respiratory signals are available within the set delay time, low level is always kept by the time-delay circuit, the audion is blocked and the buzzer does not give an alarm.
Description
Affiliated technical field
The present invention relates to a kind of respiration monitoring control instrument, specifically relate to a kind of monitor controller that is used for the respiratory failure patient.
Background technology
At present existing disclosed respiration monitoring control instrument all is to place a pick off at patient's place, nostril, by detecting the breath state that has or not or come monitor patients of patient expired air-flow by the temperature that air-flow produced, and the patient who suffers from respiratory failure is when morbidity, when promptly needing to monitor, all to connect oxygen, therefore when patients accepting oxygen inhalation, locate aerobic aspiration pipe placement sensor again, make existing respiration monitoring control instrument be restricted in the use because of the nostril.
Summary of the invention
For overcoming this deficiency that existing disclosed respiration monitoring control instrument is restricted in the use, the objective of the invention is, patient can use when oxygen uptake equally.
For achieving the above object, the technical solution adopted for the present invention to solve the technical problems is: form a respiratory failure monitoring device by a resistance wire and control circuit, described this root resistance wire bends to certain shape, be clipped in the centre of two fiber cloth, these two fiber cloth and resistance wire are bonded into one, and this resistance wire that is bonded into one is fixed on patient's abdominal part, the fluctuating that abdominal part causes because of breathing, can elongate the length of resistance wire, the resistance wire length variations can cause the variation of its resistance.Described this resistance wire and two resistance and an adjustable resistance are connected into resistance bridge, two inputs of resistance bridge connect power supply and ground connection respectively, its two outfans respectively with the positive of the difference channel of forming by an operational amplifier, inverting input connects, the voltage of its two outfans of described resistance bridge is transferred to equal when breathing no more, there is being when breathing can make the resistance bridge disequilibrium because of the resistance wire length variations can cause the variation of its resistance, the voltage of its two outfans is unequal, after this unequal voltage amplifies by the operational amplifier difference, make its outfan output voltage, output low level after a phase inverter is anti-phase, this low level triggers the delay circuit that is made of two phase inverters and makes its output low level, the base stage that is connected on the audion on the outfan of delay circuit is ended because of no-voltage, buzzer is not reported to the police because of audion ends, delay circuit is delayed time this moment, in the delay time of regulation, there is not triggering signal, its outfan uprises level by low level, the base stage of audion is because of there being the voltage conducting, buzzer is reported to the police because of the audion conducting, be that patient's apnea or shallow breathing get in the time of can not detecting, will report to the police, and when in time of time-delay of regulation, triggering signal being arranged, its outfan remains low level, the base stage of audion is ended because of no-voltage, buzzer is not reported to the police because of audion ends, and promptly patient respiration is not just often reported to the police.
No matter respiratory failure monitoring device beneficial effect of the present invention can both be implemented monitoring when being patient in general situation or in oxygen uptake.
Description of drawings
Fig. 1 is the structure chart that a resistance wire and fiber cloth are bonded into one.(another sheet does not draw)
Fig. 2 is the control circuit schematic diagram.
The specific embodiment
To specifically narrate the scheme of enforcement of the present invention with reference to accompanying drawing, in accompanying drawing 1, resistance wire 2 is lighted from a and is bent 27 times after staying one section straight line, after this get back to the b point bent 27 times to back bending again, a point b point stretches out a side of fiber cloth 1, resistance wire 2 is clipped in the centre of two fiber cloth 1, and (a slice is not drawn), and resistance wire 2 and fiber cloth 1 are bonded into one.In accompanying drawing 2, resistance wire 2 and resistance 5,6, variable resistance 4 is connected into resistance bridge, its input a point connects power supply 3, another input c point ground connection, its outfan b o'clock is connected with the normal phase input end of operational amplifier 11 through a resistance 9, another outfan d o'clock is connected with the inverting input of operational amplifier 11 through a resistance 7, be connected to a resistance 10 between the normal phase input end of operational amplifier 11 and the ground, be connected to a feedback resistance 8 between operational amplifier 11 inverting inputs and the outfan, operational amplifier 11 outfans link to each other with the input of phase inverter 12, the outfan of phase inverter 12 is connected through the input of electric capacity 13 with phase inverter 16, phase inverter 15, electric capacity 17 of serial connection between 16, connect a resistance 14 between the input of phase inverter 15 and the ground, its outfan respectively with resistance 18, an end of 19 connects, the input of another termination phase inverter 18 of resistance 18, the base stage of another termination audion 20 of resistance 19, the grounded emitter of audion 20 is connected to a buzzer 21 between audion 20 and the power supply 3.
The principle of respiratory failure monitoring device of the present invention is: the fluctuating that causes abdominal part when breathing is being arranged, the length of resistance wire 2 is changed, this variation changes the resistance of resistance wire 2, also make disequilibrium in the resistance bridge, outfan b in the resistance bridge, between the d point voltage difference is arranged, amplify again output low level after phase inverter 12 is anti-phase through operational amplifier 11 difference, this low level triggers by phase inverter 16,15 delay circuits that constitute, make phase inverter 15 output low levels, the base stage of audion 20 is ended because of no-voltage, and buzzer 20 is not reported to the police, this moment, the delay circuit time-delay, if any breathing, delay circuit triggers again in the time of time-delay, delay circuit is from the beginning time-delay again, therefore delay circuit output low level all the time, buzzer 21 is not reported to the police all the time, as breathing no more in the time of time-delay or during shallow breathing, delay circuit is the output high level after time-delay after a while, trigger triode 20 conductings, buzzer 21 can send chimes of doom because of audion 20 conductings.
