Abstract
The present invention relates to a medical method and special equipment, particularly to a monitoring method for anesthesia planes and a monitoring instrument. The method is formed by that the monitoring instrument is arranged at patients' anesthesia points, anesthesia plane range is judged by skin temperature difference of patients' anesthesia points, and the skin temperature difference is displayed by the monitoring instrument. The monitoring instrument is formed by orderly connecting a skin temperature probe, an amplifying circuit, an A/D converter, a single chip computer, a display screen and a key circuit. The present invention has the advantages of reasonable structure, safety, fast performance and exact monitoring data, and is suitable for monitoring anesthesia in any conditions.
Description
One, technical field
The present invention relates to a kind of therapy and special equipment, relate in particular to a kind of monitoring method and monitoring instrument of monitoring level of anesthesia.
Two, background technology
At present clinically, the determination methods of level of anesthesia is confined to acupuncture substantially and surveys pain, promptly uses acupuncture skin.Which position illustrates anesthesia effectively not bitterly, and this method is easy to be reliable.But following situation can't be used.：
1, the patient of child's (expressing unclear) and psychentonia for the sense of touch and the pain sensation.2, deaf mute, mental patient.3, the patient of general anesthesia+hard fiber crops.Also there is the people to judge anaesthetic effect and instruct the anesthesia medication by the variation of monitoring skin temperature, but all being to use body temperature in the multi-functional electrocardiogram monitor to pop one's head in implements, and the body temperature of multi-functional electrocardiogram monitor probe is confined to two, can only whether onset be judged to anaesthetizing, and can not the planar scope of continued narcosis.Also just can't know the anesthesia scope and whether meet requirements of operation.To at present, still there be not the level of anesthesia monitoring method and the monitoring instrument of specialty.
Three, summary of the invention
It is a kind of rational in infrastructure that order of the present invention is to provide, and Monitoring Data is accurate, safe and efficient level of anesthesia monitoring method and monitoring instrument.
Technical scheme of the present invention is: monitoring instrument is popped one's head in by Pi Wen, amplifying circuit, the A/D interpreter, single-chip microcomputer, display screen, button are pressed the circuit order and are linked to each other, and the Pi Wen probe adopts high-sensitive thermosensitive circuit resistance to make, quantity is 2-16, place the patient to anaesthetize respectively skin temperature probe and do not exist together, the Pi Wen probe is changed by ambient temperature and resistance value takes place changes, after single-chip microcomputer is subjected to this signal, pass through date processing, the size conversion of resistance value is become the height of temperature, export display screen then to, video data comprises prenarcotic contrast skin temperature, postanesthetic actual measurement skin temperature and both temperature difference are judged anaesthetic effect and level of anesthesia scope by the temperature difference.
The invention has the advantages that: by special monitoring instrument monitoring, can not only judge in time that the patient anaesthetizes back anaesthetic effect and level of anesthesia scope, for operation provides reference data accurately, and be suitable for different situations, as the deaf mute, child, general anesthesia, hard fiber crops, mental patient and spirit special nervous patient use.
Four, description of drawings
Fig. 1 is a monitoring instrument structural representation of the present invention.
Five, the specific embodiment
The present invention is a kind of monitoring method and monitoring instrument of level of anesthesia, and its method places patient's anesthesia place with monitoring instrument, by patient's anesthesia place skin temperature difference that monitoring instrument shows, judges the level of anesthesia scope.Described monitoring instrument is by Pi Wen probe 1, and amplifying circuit 2, A/D converter 3, single-chip microcomputer 4, display screen 5, button 6 are pressed the circuit order and linked to each other, and the Pi Wen probe adopts high-sensitive critesistor to make, and quantity is 2-16.
Test volume principle of the present invention is as follows: the resistance value of Pi Wen probe varies with temperature, and has certain relation between its resistance and the temperature, if the resistance of measuring under its temperature promptly can be known the pairing temperature value of this resistance value.
During concrete the use, 2-16 skin temperature probe 1 placed the diverse location of patient's anesthesia place respectively, and during measurement, the voltage on every skin temperature probe 1 two sides amplifies through amplifying circuit 2 earlier, carry out analog digital conversion by A/D converter 3 again, magnitude of voltage becomes digital signal, and single-chip microcomputer 4 is handled this digital signal, calculates corresponding resistance value, calculate the temperature value of this resistance correspondence again, show by display screen,, can read the patient's temperature value and temperature difference everywhere by button.If the temperature difference greater than the one particular value, as greater than 0.5 ℃, show that then this skin temperature probe 1 residing patient anaesthetizes the zone and anaesthetized, otherwise then anesthesia does not put in place.By analysis-by-synthesis, just can find out what position the face of anaesthetizing not is on earth.Pass in time gradually by metabolism because of anesthetics simultaneously, level of anesthesia also changes thereupon, and continuous monitoring skin temperature just can in time be found the change situation of level of anesthesia, and in time appends anesthetics.
Claims (2)
1, a kind of monitoring method of level of anesthesia is characterized in that described method for monitoring instrument is placed patient's anesthesia place skin, by patient's anesthesia place skin temperature difference that monitoring instrument shows, judges level of anesthesia; Criterion is: the temperature difference is greater than 0.5 ℃ of effective index of conduct anesthesia; Described monitoring instrument is popped one's head in (1) by Pi Wen, amplifying circuit (2), and A/D converter (3), single-chip microcomputer (4), display screen (5), button (6) is linked in sequence by circuit; Probe contact skin, display screen shows the temperature difference, the temperature difference is as the basis for estimation of level of anesthesia.
2, a kind of level of anesthesia monitoring instrument according to claim 1 is characterized in that described skin temperature probe (1) quantity is 2-16, is made by critesistor.
