Abstract
The utility model relates to an instrument. The instrument is used for monitoring the respiration situation when people sleep, and carries out the test on a plurality of aspects of the mouth, the nose, the chest and abdomen, the snore and the oxygen saturation of blood. The monitor is composed of a test head, an amplifier, an analog-to-digital conversion, an interface circuit, a single-board computer, and an input and an output devices. The instrument provides the basis for the medical diagnosis.
Description
The medical diagnostic equipment of breathing when this utility model belongs to a kind of monitoring sleep.
Asphyxia during sleep is a kind of frequently-occurring disease of male more than 40 years old.This situation occurs and can make the patient body anoxia, directly influence the patient and work normally daytime, learn, what situation was serious also can make people's death by suffocation.
The purpose of this utility model provides a kind of monitoring and diagnostic device.This equipment is successive test port, nose, breast abdominal respiration and blood oxygen saturation simultaneously.The breath state of comprehensive monitoring people when sleep is for medical diagnosis provides foundation.
Structured flowchart of the present utility model as shown in Figure 1, comprising: mouth and nose measuring head (1), breast abdomen measuring head (2), snoring measuring head (3), blood oxygen measuring head and blood oxygen saturation instrument (4), amplifier (5) (6) (7) (8), electric voltage frequency (V/F) changer (9), (10), (11), (12), interface circuit (13), single board computer (14), printer (15), display (16), input keyboard (17).
Mouth and nose measuring head (1) as shown in Figure 2, constitute by a Y type four-way pipe (18),, be positioned at before the blow vent of oral cavity at tube interior, one critesistor (19) is arranged, and this resistance will become corresponding current changing signal by breathing the variations in temperature signal that produces by lead.The electric current of output is amplified by the amplifying circuit of back.
Breast abdomen measuring head (2) is as shown in Figure 3: (20) are a silicon rubber hose, (21) (22) are two electrodes with epoxy sealing, (23) (24) are respectively the hook of being with on the electrode (21) (22), (25) (26) are two conductive pins that link to each other with (21) (22) respectively, and (27) are for filling at the inner saturated solution of zinc sulfate of flexible pipe (20).(25) effect of (26) two conductive pins is, when having bubble to exist in the flexible pipe (20), and still can be between two electrodes (21) (22) normally by the mutual conducting of saturated solution of zinc sulfate.
The amplification of mouth, nose, breast abdominal respiration signal and snoring signal, mould/transformation of variables principle be as shown in Figure 4: S among the figure
1Be the measuring head input signal, test signal is amplified through operational amplifier A, through voltage/frequency (V/F) conversion, obtains numerical frequency signal S at circuit output end again
3This signal is received interface circuit (13).S among Fig. 4
2Be the Input Monitor Connector signal.
Oxygen saturation signal amplifies and mould/the transformation of variables schematic diagram as shown in Figure 5.Oxygen saturation signal S
4Take from the output of blood oxygen saturation instrument, the blood oxygen saturation instrument selects for use Japan to produce Ohmeda Biox 3700 Pulse Oxieter in the present embodiment.Test signal S
4Through amplifier A and voltage/frequency conversion (V/F), export digital signal S at last
6To interface circuit (13).S among Fig. 5
5Be the Input Monitor Connector signal.
The test signal of above-mentioned each measuring head through amplifying and mould/transformation of variables, is delivered to single board computer (14) by interface circuit (13) and is deposited, handles respectively.The duty of single board computer (14) is subjected to the various command control of keyboard (17) input, and all orders and test signal all can go up at display (16) and show, printer (15) is used for the printout test result.
The respiratory apnea monitor of realizing according to such scheme has following function: test and write down the asphyxia number of times of mouth, nose, breast abdomen, the start-stop moment and persistent period that each time-out takes place; Test and record snoring situation; Measure and write down blood oxygen saturation and be lower than 90% number of times, the minima of each the start-stop moment, time and blood oxygen saturation.
The measuring head that this monitor adopted is does not have the test of wound.This instrument utilizes single board computer, makes instrument performance stable, and easy to operate, the result is accurate, and can printout monitoring report.
Embodiment is shown in accompanying drawing 1,2,3,4,5, and the snoring measuring head (3) in the accompanying drawing 1 is stayed body by a utmost point and constituted, as shown in Figure 6.The model of the used single board computer of present embodiment is BCM-81.
Claims (4)
1, a kind of respiratory apnea monitor, it is characterized in that four measuring heads (1) (2) (3) (4) in this monitor, be connected in series successively with separately amplifier (5) (6) (7) (8) and voltage/frequency changer (9) (10) (11) (12) respectively, four road frequency signals after the voltage/frequency conversion, by interface circuit (13) input single board computer (14), as input-output equipment, this single board computer also is furnished with input keyboard (15), Output Display Unit (16) and output printer (17).
2, the monitor of mentioning in the claim 1 is characterized in that the measuring head of this monitor is respectively: mouth and nose measuring head (1), breast abdomen measuring head (2), snoring measuring head (3), blood oxygen measuring head and blood oxygen saturation instrument (4).
3, the monitor of mentioning in claim 1 and the claim 2, it is characterized in that: the core of mouth and nose measuring head (1) is a critesistor (19), this critesistor places the inside of a Y type four-way pipe (18), takes out the signal of telecommunication that the reflection thermistor temp changes by lead.
4, the monitor of mentioning in claim 1 and the claim 2, its mesothorax abdomen measuring head (2) is equipped with enclosed electrode (21) (22) by two ends, the silicone rubber tube (20) that saturated solution of zinc sulfate (27) are equipped with in inside constitutes, its electrode (21) (22) is characterised in that: in silicone rubber tube (20) inside, two electrodes respectively are connected to a conductive pin (25) (26).
